    Worldwide trends in body-mass index, underweight, overweight, and obesity from 1975 to 2016: a pooled analysis of 2416 population-based measurement studies in 128·9 million children, adolescents, and adults.2017In: The Lancet, ISSN 0140-6736, E-ISSN 1474-547X, Vol. 390, no 10113, p. 2627-2642Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults.

    METHODS: We pooled 2416 population-based studies with measurements of height and weight on 128·9 million participants aged 5 years and older, including 31·5 million aged 5-19 years. We used a Bayesian hierarchical model to estimate trends from 1975 to 2016 in 200 countries for mean BMI and for prevalence of BMI in the following categories for children and adolescents aged 5-19 years: more than 2 SD below the median of the WHO growth reference for children and adolescents (referred to as moderate and severe underweight hereafter), 2 SD to more than 1 SD below the median (mild underweight), 1 SD below the median to 1 SD above the median (healthy weight), more than 1 SD to 2 SD above the median (overweight but not obese), and more than 2 SD above the median (obesity).

    FINDINGS: Regional change in age-standardised mean BMI in girls from 1975 to 2016 ranged from virtually no change (-0·01 kg/m2 per decade; 95% credible interval -0·42 to 0·39, posterior probability [PP] of the observed decrease being a true decrease=0·5098) in eastern Europe to an increase of 1·00 kg/m2 per decade (0·69-1·35, PP>0·9999) in central Latin America and an increase of 0·95 kg/m2 per decade (0·64-1·25, PP>0·9999) in Polynesia and Micronesia. The range for boys was from a non-significant increase of 0·09 kg/m2 per decade (-0·33 to 0·49, PP=0·6926) in eastern Europe to an increase of 0·77 kg/m2 per decade (0·50-1·06, PP>0·9999) in Polynesia and Micronesia. Trends in mean BMI have recently flattened in northwestern Europe and the high-income English-speaking and Asia-Pacific regions for both sexes, southwestern Europe for boys, and central and Andean Latin America for girls. By contrast, the rise in BMI has accelerated in east and south Asia for both sexes, and southeast Asia for boys. Global age-standardised prevalence of obesity increased from 0·7% (0·4-1·2) in 1975 to 5·6% (4·8-6·5) in 2016 in girls, and from 0·9% (0·5-1·3) in 1975 to 7·8% (6·7-9·1) in 2016 in boys; the prevalence of moderate and severe underweight decreased from 9·2% (6·0-12·9) in 1975 to 8·4% (6·8-10·1) in 2016 in girls and from 14·8% (10·4-19·5) in 1975 to 12·4% (10·3-14·5) in 2016 in boys. Prevalence of moderate and severe underweight was highest in India, at 22·7% (16·7-29·6) among girls and 30·7% (23·5-38·0) among boys. Prevalence of obesity was more than 30% in girls in Nauru, the Cook Islands, and Palau; and boys in the Cook Islands, Nauru, Palau, Niue, and American Samoa in 2016. Prevalence of obesity was about 20% or more in several countries in Polynesia and Micronesia, the Middle East and north Africa, the Caribbean, and the USA. In 2016, 75 (44-117) million girls and 117 (70-178) million boys worldwide were moderately or severely underweight. In the same year, 50 (24-89) million girls and 74 (39-125) million boys worldwide were obese.

    INTERPRETATION: The rising trends in children's and adolescents' BMI have plateaued in many high-income countries, albeit at high levels, but have accelerated in parts of Asia, with trends no longer correlated with those of adults.

    Dental beliefs: factor structure of the revised dental beliefs survey in a group of regular dental patients2009In: European Journal of Oral Sciences, ISSN 0909-8836, E-ISSN 1600-0722, Vol. 117, no 6, p. 720-727Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to investigate the factor structure of the revised dental beliefs survey (DBS-R) in a group of regular dental patients. The study group consisted of 278 patients (mean age 54 yr), 61% of whom were women. The DBS-R item mean value was 1.6. Principal component analysis (PCA) and confirmatory factor analysis (CFA) were performed. The initial PCA among the 28 DBS-R items showed four factors with eigenvalues of > 1 explaining 67% of the total variance. Five different CFA models were tested. The final model revealed a four-factor solution with one second-order factor (i.e. a hierarchical CFA). Thus, the latent second-order variable, 'dental beliefs', explains the variance from all DBS-R items through the four first-order factors labeled 'ethics', 'belittlement', 'communication and empathy', and 'control and anxiety'. The results suggest a somewhat different factor structure of DBS-R than previously reported for dental-fear patients. Hence, the underlying factor structure of the DBS-R may differ between different patient groups. The results point towards the use of the original 28-item DBS-R and interpreting the scale as measuring an overall construct of 'dental beliefs' and thus patients' attitudes and feelings related to dentists and dentistry.

    Health effects of overweight and obesity in 195 countries over 25 years2017In: New England Journal of Medicine, ISSN 0028-4793, E-ISSN 1533-4406, Vol. 377, no 1, p. 13-27Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Although the rising pandemic of obesity has received major attention in many countries, the effects of this attention on trends and the disease burden of obesity remain uncertain.

    METHODS: We analyzed data from 68.5 million persons to assess the trends in the prevalence of overweight and obesity among children and adults between 1980 and 2015. Using the Global Burden of Disease study data and methods, we also quantified the burden of disease related to high body-mass index (BMI), according to age, sex, cause, and BMI in 195 countries between 1990 and 2015.

    RESULTS: In 2015, a total of 107.7 million children and 603.7 million adults were obese. Since 1980, the prevalence of obesity has doubled in more than 70 countries and has continuously increased in most other countries. Although the prevalence of obesity among children has been lower than that among adults, the rate of increase in childhood obesity in many countries has been greater than the rate of increase in adult obesity. High BMI accounted for 4.0 million deaths globally, nearly 40% of which occurred in persons who were not obese. More than two thirds of deaths related to high BMI were due to cardiovascular disease. The disease burden related to high BMI has increased since 1990; however, the rate of this increase has been attenuated owing to decreases in underlying rates of death from cardiovascular disease.

    CONCLUSIONS: The rapid increase in the prevalence and disease burden of elevated BMI highlights the need for continued focus on surveillance of BMI and identification, implementation, and evaluation of evidence-based interventions to address this problem.

    Suicidal drowning deaths in northern Sweden 1992-2009: The role of mental disorder and intoxication2015In: Journal of Forensic and Legal Medicine, ISSN 1752-928X, E-ISSN 1878-7487, Vol. 34, p. 168-172Article in journal (Refereed)
    Abstract [en]

    Suicides by drowning have received limited attention by researchers. A recent finding that almost one-third of all drowning deaths in Sweden were classified as suicide instigated this study. We identified 129 cases of suicide by drowning in Northern Sweden and analyzed the circumstances and the psychiatric history prior to the suicide. Information was obtained from autopsy, police and medical records, as well as from the National Inpatient Register. One-third of the suicide victims had previously attempted suicide and half of the victims had been hospitalized due to mental health problems. One-third of these had left the hospital less than one week before the suicide. Alcohol and psychoactive drugs were present in 16% and 62% of the cases, respectively. A history of mental disorder and previous suicide attempt (s), especially by drowning, is an ominous combination necessitating efficient clinical identification, treatment and follow-up if a complete suicide is to be prevented.

    Component that make a midwife grow personally and professionally: A qualitative meta-synthesis2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background:

    Midwifery care is an essential component of providing quality maternal and child health care. Mother and new born health outcomes depends on the quality of education, license to practice, the scope of practice, sufficient resources, referral mechanisms and effective teamwork. The aim of this meta-synthesis was to describe components building midwifery professionalism for delivery of quality care. Method: This study was a meta-synthesis focusing to describe the components needed for building midwifery professionalism for delivery of quality care in high, low and middle-income countries. After assessing for relevance and quality in peer-reviewed journals, 30 qualitative studies were included from 2009 to 2018, written in English. This involved an electronic search using the following databases: PubMed, CINAHL, web of Science, Google Scholar, Summon and manually search. Result: After analysis and synthesis, the major findings can be summarized in two components; Clinical experiences make the midwives’ grow personally and professionally and an enabling environment enhances the midwives’ personal and professional development. Subcategories were; Collaboration with other health professionals and with colleges/ colleagues at the workplace, Extensive hands on clinical experience, Professional management of the workplace, Quality pre-service education and quality of the midwifery educators, In-service training, Policies and guidelines regulate the midwifery workforce, Being a member of a midwifery association. Conclusion: To ensure mothers quality midwifery care; midwives play a critical role in strengthening the midwifery workforce in high and low-middle income countries. This study highlights the benefits of building capacity for strengthening midwives and the midwifery profession. Clinical implications: There is a need to improving the educational status, improving policy and practice of health care program and facilitate the necessary resources. There is need for further research to identify how much improvements the newly deployed midwifery cadre service will bring in the field of quality midwifery care personally and professionally especially in rural setting.

    Supportive components of care during cesarean section birth: A qualitative meta-synthesis2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background

    : Caesarean section is the most common surgery worldwide today. The midwives support is therefore of uttermost important for women undergoing caesarean section. Aim: The aim of the meta-synthesis was to explore the experience related to planned and unplanned cesarean sections among primipara and multipara women in hospital settings worldwide. Method: This study is a meta-synthesis with meta-ethnographic analysis on women’s experiences of caesarean section birth. This is a qualitative research based on scientific literature. The inclusion criterion was peer-review qualitative articles from different original articles about women's experiences. Results: Five categories emerged: Caring attitude and behaviour, pre-existing imagination, relational influence, the need for caring and information. The findings suggest that nurse-midwife enhance their support and increase the women’s knowledge on caesarean section birth in order to improve the experience and also for women to make good choices. Women are influenced by people near to them when choosing to have a cesarean section or not. The mothers face challenges for postoperative recovery and quality of care. Midwives have a duty to assist these mothers. Conclusion: The findings emphasize the importance of person-centered communication skills and relationships in supporting a woman during caesarian section. Organizational systems and services that facilitate continuity of care giver for example, continuity of midwifery care or peer support models, are more likely to facilitate supportive care and a trust-building relationship. Clinical implication: The findings from this study can be used for educational purposes, and to create awareness about the role of midwifery care in relation to CS.

    Parent’s perceptions experiences and attitudes about kangaroo mother care in neonatal wards: A qualitative meta-synthesis2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background:

    The knowledge of facility-based kangaroo mother care (KMC) in Bangladesh is comparatively recent; few facilities have been taking steps towards KMC service. Each year more than a million babies die due to the complication of prematurity. To eliminate the deaths due to prematurity, it is very important to share knowledge about the implementation, experiences, challenges and barriers for KMC practice to promote KMC intervention in the developing countries. Aim: To examine parents’ perceptions, experiences and attitude towards KMC in neonatal wards. Method: This study was a meta-synthesis focusing on parents’ perceptions and experiences of KMC. The included studies used several different qualitative methodologies compiled using Meta ethnography. Result: The results comprised of three categories were identified in this study. The First category was the Barriers towards KMC. This category comprised four preliminary patterns of parent’s perceptions of barriers to have KMC: Separating due to prematurity, Fear of harming, Pain prevented closeness, and Fear prevented closeness. The second category was facilitating factors for KMC, which covered parents’ experiences of the consult support expressed in four preliminary patterns: Own wish for closeness, Having positive experience and Support from the staff. The third category Benefits for KMC included three preliminary patterns of positive perceptions of KMC made by parents: Calming, warming and bonding, connecting with the premature baby and Being able to act as a parent. Conclusion: In this meta-synthesis, the main findings were realized into three categories of KMC- Barriers towards KMC, facilitating factors of KMC, Benefits of KMC. This is a low-cost and effectiveness method of reducing infant mortality. Clinical implications: Health care professionals have opportunities to implement Kangaroo Mother Care in low resource settings. First health care professionals have to be encouraged in all postnatal wards. Secondly, parents need to be aware about KMC so that they can promote their baby’s health and eventually save their baby’s life.

    Skeletal muscle morphology and risk of cardiovascular disease in elderly men2015In: European Journal of Preventive Cardiology, ISSN 2047-4873, E-ISSN 2047-4881, Vol. 22, no 2, p. 231-239Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: While it is well known that physical inactivity is a major risk factor for cardiovascular disease, there is still a search for the mechanisms by which exercise exerts its positive effect. Skeletal muscle fibre type can be affected to some extent by exercise, and different fibre types possess different anti-inflammatory and glucometabolic properties that may influence cardiovascular disease risk.

    DESIGN: Population-based cohort study.

    METHODS: We investigated relations of skeletal muscle morphology to risk of cardiovascular events in a sample of 466 71-year-old men without cardiovascular disease, of which 295 were physically active (strenuous physical activity at least 3 h/week).

    RESULTS: During a median of 13.1 years of follow up, 173 major cardiovascular events occurred. Among physically active men, 10% higher proportion of type-I (slow-twitch oxidative) fibres was associated with a hazard ratio (HR) of 0.84 (95% confidence interval 0.74-0.95) for cardiovascular events, and 10% higher proportion of type-IIx (fast-twitch glycolytic) fibres was associated with a HR of 1.24 (1.06-1.45), adjusting for age. Similar results were observed in several sets of multivariable-adjusted models. No association of muscle fibre type with risk of cardiovascular events was observed among physically inactive men.

    CONCLUSIONS: Higher skeletal muscle proportion of type-I fibres was associated with lower risk of cardiovascular events and a higher proportion of type-IIx fibres was associated with higher risk of cardiovascular events. These relations were only observed in physically active men. Skeletal muscle fibre composition may be a mediator of the protective effects of exercise against cardiovascular disease.

    Genetic association study of QT interval highlights role for calcium signaling pathways in myocardial repolarization2014In: Nature Genetics, ISSN 1061-4036, E-ISSN 1546-1718, Vol. 46, no 8, p. 826-836Article in journal (Refereed)
    Abstract [en]

    The QT interval, an electrocardiographic measure reflecting myocardial repolarization, is a heritable trait. QT prolongation is a risk factor for ventricular arrhythmias and sudden cardiac death (SCD) and could indicate the presence of the potentially lethal mendelian long-QT syndrome (LQTS). Using a genome-wide association and replication study in up to 100,000 individuals, we identified 35 common variant loci associated with QT interval that collectively explain similar to 8-10% of QT-interval variation and highlight the importance of calcium regulation in myocardial repolarization. Rare variant analysis of 6 new QT interval-associated loci in 298 unrelated probands with LQTS identified coding variants not found in controls but of uncertain causality and therefore requiring validation. Several newly identified loci encode proteins that physically interact with other recognized repolarization proteins. Our integration of common variant association, expression and orthogonal protein-protein interaction screens provides new insights into cardiac electrophysiology and identifies new candidate genes for ventricular arrhythmias, LQTS and SCD.

    A new hamstring test to complement the common clinical examination before return to sport after injury2010In: Knee Surgery, Sports Traumatology, Arthroscopy, ISSN 0942-2056, E-ISSN 1433-7347, Vol. 18, no 12, p. 1788-1803Article in journal (Refereed)
    Abstract [en]

    PURPOSE: The aim was to introduce and evaluate the reliability and validity of an active hamstring flexibility test as a complement to common clinical examination when determining safe return to sport after hamstring injury.

    METHODS: Eleven healthy subjects (28 years) were tested on repeated occasions, and 11 athletes (21 years) with MRI-verified acute hamstring strain were tested when common clinical examination revealed no signs of remaining injury, i.e. there was no differences between the legs in palpation pain, manual strength tests, and passive straight leg raise. Flexibility, i.e. highest range of motion of three consecutive trials, was calculated from electrogoniometer data during active ballistic hip flexions and conventional passive slow hip-flexions in a supine position. A VAS-scale (0-100) was used to estimate experience of insecurity during active tests.

    RESULTS: No significant test-retest differences were observed. Intra-class correlation coefficients ranged 0.94-0.99 and coefficients of variation 1.52-4.53%. Active flexibility was greater (23%) than passive flexibility. In the athletes, the injured leg showed smaller (8%) active, but not passive, flexibility than the uninjured leg. Average insecurity estimation was 52 (range 28-98) for the injured and 0 for the uninjured leg, respectively.

    CONCLUSION: The new test showed high reliability and construct validity; furthermore, it seems to be sensitive enough to detect differences both in active flexibility and in insecurity after acute hamstring strains at a point in time when the commonly used clinical examination fails to reveal injury signs. Thus, the test could be a complement to the common clinical examination before the final decision to return to sport is made.

    Hyperkalemia after initiating renin-angiotensin system blockade: The Stockholm creatinine measurements (SCREAM) project2017In: Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, ISSN 2047-9980, E-ISSN 2047-9980, Vol. 6, no 7, article id e005428Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Concerns about hyperkalemia limit the use of angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin receptor blockers (ARBs), but guidelines conflict regarding potassium-monitoring protocols. We quantified hyperkalemia monitoring and risks after ACE-I/ARB initiation and developed and validated a hyperkalemia susceptibility score.

    METHODS AND RESULTS: We evaluated 69 426 new users of ACE-I/ARB therapy in the Stockholm Creatinine Measurements (SCREAM) project with medication initiation from January 1, 2007 to December 31, 2010, and follow-up for 1 year thereafter. Three fourths (76%) of SCREAM patients had potassium checked within the first year. Potassium >5 and >5.5 mmol/L occurred in 5.6% and 1.7%, respectively. As a comparison, we propensity-matched new ACE-I/ARB users to 20 186 new β-blocker users in SCREAM: 64% had potassium checked. The occurrence of elevated potassium levels was similar between new β-blocker and ACE-I/ARB users without kidney disease; only at estimated glomerular filtration rate <60 mL/min per 1.73 m(2) were risks higher among ACE-I/ARB users. We developed a hyperkalemia susceptibility score that incorporated estimated glomerular filtration rate, baseline potassium level, sex, diabetes mellitus, heart failure, and the concomitant use of potassium-sparing diuretics in new ACE-I/ARB users; this score accurately predicted 1-year hyperkalemia risk in the SCREAM cohort (area under the curve, 0.845, 95% CI: 0.840-0.869) and in a validation cohort from the US-based Geisinger Health System (N=19 524; area under the curve, 0.818, 95% CI: 0.794-0.841), with good calibration.

    CONCLUSIONS: Hyperkalemia within the first year of ACE-I/ARB therapy was relatively uncommon among people with estimated glomerular filtration rate >60 mL/min per 1.73 m(2), but rates were much higher with lower estimated glomerular filtration rate. Use of the hyperkalemia susceptibility score may help guide laboratory monitoring and prescribing strategies.

    "There Are Remaining Challenges in Bangladesh" A National Assessment Strategy Supports Reaching International Midwifery Standards Education: A focus group inquiry among midwifery faculty in Bangladesh2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Delivery by unskilled birth attendant is causing many maternal and neonatal deaths. Midwives can reduce maternal and neonatal deaths by providing skilled delivery care. To prepare skilled midwives a National Assessment Strategy for Midwifery Education Standards has been introduced.

    Aim: To describe midwifery faculty members’ perceptions of how to affirm quality midwifery education in Bangladesh using a national assessment strategy.

    Methods: A qualitative research design was chosen using a context-specific accreditation assessment tool, guided by the Global Standards for Midwifery Education. The participants were 33 midwifery teachers, and data were analyzed with content analysis.

    Results: The findings indicate that Bangladesh should be prepared to implement the Global Standards for Midwifery Education Accreditation Programmes. The assessment strategy has prepared the faculty for accreditation and paved the way through the development of standards in the tool, overcoming barriers, and using the possible facilitators.

    Conclusion: There are remaining challenges in Bangladesh regarding "moving midwifery". Midwifery teachers demand for separate faculty from nursing. Promotion system for careers development can be initiated. Updating teachers knowledge, having adequate number of teachers with competencies, and maintained collaboration between teaching and clinical practice organizations are important for "moving midwifery" in Bangladesh.

    Clinical application: The present study results can be useful for midwifery education and clinical practice improvement.

    Cytokine-mediated inflammation is independently associated with insulin sensitivity measured by the euglycemic insulin clamp in a community-based cohort of elderly men2011In: International Journal of Clinical and Experimental Medicine, ISSN 1940-5901, E-ISSN 1940-5901, Vol. 4, no 2, p. 164-168Article in journal (Refereed)
    Abstract [en]

    Both clinical and experimental studies suggest a close relation between an inflammatory state and insulin resistance. We investigated the association between cytokine-mediated inflammation (high sensitivity C reactive protein [hsCRP] and interleukin [IL] 6) and insulin sensitivity (insulin-mediated glucose disposal rate, assessed by the euglycemic insulin clamp) in a community-based cohort, with subgroup analyses of normal weight individuals without diabetes mellitus and metabolic syndrome (NCEP). hsCRP and IL- 6 were inversely associated with insulin sensitivity (multivariable-adjusted regression coefficient for 1-SD increase of hsCRP -0.12 (-0.21-(-0.03), p=0.01) and of IL-6 - 0.11 (-0.21-(-0.02), p=0.01) in models adjusting for age and components of the metabolic syndrome (systolic and diastolic blood pressure, antihypertensive drugs, HDL-cholesterol, triglycerides, fasting plasma glucose, waist circumference). The multivariable-adjusted association between hsCRP, IL-6 and insulin sensitivity were of a similar magnitude in normal weight individuals without diabetes and without the metabolic syndrome. Our data show that cytokine -mediated subclinical inflammation is independently associated with decreased insulin sensitivity also in apparently metabolically healthy normal weight individuals, indicating that the interplay between inflammatory processes and insulin resistance is present already in the early stages of the development of glucometabolic disease.

    Women’s and health care provider perceptions and experiences of bottlenecks in midwifery care: A qualitative meta-synthesis2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background:

    Women die from preventable causes during pregnancy and childbirth and often in relation to delays in midwifery care. Professional hierarchies might hamper the rights and desires of midwives in provision of normal birth in terms of the provision of quality care to all women and newborns. In health systems where decision making in normal births are influence by doctors this is particularly relevant, with women themselves subordinate to all health care professionals. Aim: The aim of this meta-synthesis was to examine women’s and health care provider’s perceptions and experiences of bottlenecks in midwifery care related to availability, accessibility, acceptability and quality of midwifery care. Method: This study was a qualitative meta-synthesis with a deductive approach, 15 article were selected for this qualitative meta-synthesis. A framework for the evaluation of quality of care and coverage of health services was used for the deductive approach. Results: Four categories emerged based on availability, accessibility, acceptability and quality of care. The delays were due to less awareness of danger signs of severe complications in the community, and delays in decision making by male family members and less empowerment of women, and lack of collaboration between health care professionals. We also identified how to overcome this situation. Conclusion: Midwifes may provide quality maternal care to all women and children and earn trust from community people to promote normal pregnancy and birth and prevent delays when complications arise. Clinical implications: Midwives can provide continuity care and through collaboration with other health care professionals advocate for women empowerment.

    Parents’ and health care providers’ perceptions and experiences of supportive care in neonatal wards: A qualitative metasynthesis2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background:

    Four million infants die with in the first month of life and 27% of these deaths are directly related to low birth weight (LBW) or preterm birth. The main causes of infant death in premature and LBW infants is neonatal infections. It is thus crucial that the infant is taken care of in an appropriate way regarding caring and feeding and that care is provided to improve the child’s chances of survival and to lay the foundation for a healthy life. Aim: The aim of this meta-synthesiswas to examine parent`s and health care providers perceptions and experiences of supportive care in neonatal wards. Method: A qualitative meta-synthesis based on peer-reviewed scientific literature, and meta-ethnographic analysis method. In this meta-synthesis 16 articles were included. Result: The results comprised of two categories, Parents’ perspective of supportive strategies with eight corresponding preliminary patterns and Health care providers’ perspective of supportive strategies with six corresponding preliminary patterns. In the result section, each categories are presented with its corresponding preliminary patterns. The mothers experienced that the baby was unstable and therefore they wanted to be close to the baby at all times if something happened. Important was closeness to the infant is important, parental support according to needs, adequate communication and information with parents, genuine caring and continuous support to get close to the child. It also meant less light and less noise and privacy for the infant and the parent in the NICU ward.

    Conclusion

    Parents wanted to be able to be with his infant as rapidly after birth be reunited in case something happened. The importance of receiving information about their infant’s condition underpinned all communications that the parents undertook with NICU staff both in co-care when together with the child and part-care, when separated. Information for the parents was an important requirement of accepting their situation and immediately affected their anxiety. Clinical implications: The organizers of care must take in account that parents and infants will not be befitted by being cared for apart from each other. When planning for co-care enabling infants to be close to the parents, the mother-baby dyad should be prioritized. Context specific interview studies are suggested on co-care and part-care, parents and care providers perspectives.

    Perceived occupational gaps one year after stroke: An explorative study2011In: Journal of Rehabilitation Medicine, ISSN 1651-2081, Vol. 44, no 1, p. 36-42Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To explore and describe factors associated with occupational gaps and to identify factors at 3 months that predict occupational gaps one year post-stroke. A gap, a restriction in participation, is considered to be present when there is a discrepancy between what the individual wants to do and what they actually do in everyday life. DESIGN: Prospective longitudinal study. SUBJECTS: Two hundred persons with stroke. METHODS: Data from the Occupational Gaps Questionnaire, one year post-stroke, was used as the dependent variable in 3- and 12-month regression analyses. Domains of the Stroke Impact Scale, global life satisfaction, demographic and medical factors were used as independent variables. RESULTS: At 3 months, activities of daily living abilities, social participation and not being born in Sweden predicted occupational gaps at 12 months. Stroke severity and not being born in Sweden and 3 factors at 12 months: social participation, self-rated recovery, and global life satisfaction were associated with occupational gaps. CONCLUSION: Activities of daily living ability at 3 months predicted occupational gaps after stroke. Thus, it is possible to identify early on, and provide interventions for, those that risk participation restrictions. Not being born in the country might be an indicator of a risk for participation restrictions.

    Förlossningsrädsla: En begreppsanalys ur barnmorskans perspektiv2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Fear of childbirth affects about one-fifth of all pregnant women and midwives face these in their work.

    Aim: The aim was to analys the concept fear of childbirth from a midwife perspective.

    Methods: A concept analysis with a hybrid model. First a theoretical phase with a search for literature, thereafter a fieldwork phase where five midwifes where interviewed followed by a final analytic phase.

    Results: Fear of childbirth is something that can affect women before, during or after pregnancy and childbirth. Fear of childbirth for primiparous women can be a lack of confidence in her ability to give birth, and for multiparous women have had a previous traumatic birth experience. The midwives described that fear of childbirth was a complex concept. Women did not usually use the word fear of childbirth, but the midwives interpreted what they noticed or saw in the woman as manifestations of fear of childbirth.

    Conclusion: Midwives use the concept in different ways and call for a clearer definition and way of working with fear of childbirth. The fear of childbirth is a great suffering for the pregnant woman and therefore the authors of this thesis consider that preventive work is important and that the midwife has a central and important role.

    Clinical Applicability: Midwives can use this study to develop their knowledge of fear of childbirth and see how other midwives view on the concept fear of childbirth.

    Benefits of resistance exercise in lean women with fibromyalgia: involvement of IGF-1 and leptin2017In: BMC Musculoskeletal Disorders, ISSN 1471-2474, E-ISSN 1471-2474, Vol. 18, no 1, article id 106Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Chronic pain and fatigue improves by exercise in fibromyalgia (FM) but underlying mechanisms are not known. Obesity is increased among FM patients and associates with higher levels of pain. Symptom improvement after aerobic exercise is affected by body mass index (BMI) in FM. Metabolic factors such as insulin-like growth factor 1 (IGF-1) and leptin may be involved. In this study, the aim was to evaluate the role of metabolic factors in lean, overweight and obese women during resistance exercise, in relation to symptom severity and muscle strength in women with FM.

    METHODS: Forty-three women participated in supervised progressive resistance exercise, twice weekly for 15-weeks. Serum free and total IGF-1, IGF-binding protein 3 (IGFBP3), adiponectin, leptin and resistin were determined at baseline and after 15-weeks. Level of current pain was rated on a visual analogue scale (0-100 mm). Level of fatigue was rated by multidimensional fatigue inventory (MFI-20) subscale general fatigue (MFIGF). Knee extension force, elbow flexion force and handgrip force were assessed by dynamometers.

    RESULTS: Free IGF-1 (p = 0.047), IGFBP3 (p = 0.025) and leptin (p = 0.008) were significantly decreased in lean women (n = 18), but not in the overweight (n = 17) and the obese (n = 8). Lean women with FM benefited from resistance exercise with improvements in current pain (p= 0.039, n = 18), general fatigue (MFIGF, p = 0.022, n = 18) and improved elbow-flexion force (p = 0.017, n = 18). In overweight and obese women with FM there was no significant improvement in pain or fatigue but an improvement in elbow flexion (p = 0.049; p = 0.012) after 15 weeks of resistance exercise.

    CONCLUSION: The clearest clinical response to resistance exercise was found in lean patients with FM. In these individuals, individualized resistance exercise was followed by changes in IGF-1 and leptin, reduced pain, fatigue and improved muscular strength. In overweight and obese women FM markers of metabolic signaling and clinical symptoms were unchanged, but strength was improved in the upper limb. Resistance exercise combined with dietary interventions might benefit patients with FM and overweight.

    TRIAL REGISTRATION: The trial was registered 21 of October 2010 with ClinicalTrials.gov identification number: NCT01226784 .

    Sex and maturity status affected the validity of a submaximal cycle test in adolescents2018In: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 107, no 1, p. 126-133Article in journal (Refereed)
    Abstract [en]

    AIM: This study assessed the validity and reliability of the Ekblom-Bak (EB) submaximal cycle test in adolescents and identified any sex- or maturity-related factors for prediction errors.

    METHODS: We recruited 50 healthy subjects through a public announcement in Stockholm, Sweden, in 2016. The 27 boys and 23 girls were aged 10-15 years and in Tanner stages I-IV. They performed an EB test and incremental treadmill running test for direct measurement of maximal oxygen uptake (VO2 max).

    RESULTS: The estimation error of VO2 max was 0.09 L/min. The correlation (r) was 0.86, and the standard error of the estimate (SEE) was 0.29 L/min. The largest overestimation was seen in prepubertal boys (0.49 L/min). The best precision of the EB test was achieved when boys in Tanner stages I and II were re-calculated using the prediction equation developed for adult women. This yielded a mean difference of -0.05 L/min, r = 0.92 and SEE 0.23 L/min, in the entire sample. The prediction error was lowered in boys, but not girls, with increasing pubertal maturity.

    CONCLUSION: The EB test was reasonably valid in adolescents, seemed to be related to sex and maturity status, and our findings support its use.

    Assay for screening for six antimalarial drugs and one metabolite using dried blood spot sampling, sequential extraction and ion-trap detection2010In: Bioanalysis, ISSN 1757-6180, E-ISSN 1757-6199, Vol. 2, no 11, p. 1839-1847Article in journal (Refereed)
    Abstract [en]

    Background: More parasites are becoming resistant to antimalarial drugs, and in many areas a change in first-line drug treatment is necessary. The aim of the developed assay is to help determine drug use in these areas and also to be a complement to interviewing patients, which will increase reliability of surveys.

    Results: This assay detects quinine, mefloquine, sulfadoxine, pyrimethamine, lumefantrine, chloroquine and its metabolite desethylchloroquine in a 100-mu l dried blood spot. Most of the drugs also have long half-lives that make them detectable at least 7 days after administration. The drugs are extracted from the dried blood spot with sequential extraction (due to the big differences in physicochemical properties), solid-phase extraction is used as sample clean-up and separation is performed with gradient-LC with MS ion-trap detection.

    Conclusion: Detection limits (S/N > 5:1) at 50 ng/ml or better were achieved for all drugs except lumefantrine (200 ng/ml), and thus can be used to determine patient compliance. A major advantage of using the ion-trap MS it that it will be possible to go back into the data and look for other drugs as needed.

    No evidence for xenotropic murine leukemia-related virus infection in Sweden using internally controlled multiepitope suspension array serology2012In: Clinical and Vaccine Immunology, ISSN 1556-6811, E-ISSN 1556-679X, Vol. 19, no 9, p. 1399-1410Article in journal (Refereed)
    Abstract [en]

    Many syndromes have a large number of differential diagnoses, a situation which calls for multiplex diagnostic systems. Myalgic encephalomyelitis (ME), also named chronic fatigue syndrome (CFS), is a common disease of unknown etiology. A mouse retrovirus, xenotropic murine leukemia-related virus (XMRV), was found in ME/CFS patients and blood donors, but this was not corroborated. However, the paucity of serological investigations on XMRV in humans prompted us to develop a serological assay which cover many aspects of XMRV antigenicity. It is a novel suspension array method, using a multiplex IgG assay with nine recombinant proteins from the env and gag genes of XMRV and 38 peptides based on known epitopes of vertebrate gamma-retroviruses. IgG antibodies were sought in 520 blood donors and 85 ME/CFS patients and in positive-and negative-control sera from animals. We found no differences in seroreactivity between blood donors and ME/CFS patients for any of the antigens. This did not support an association between ME/CFS and XMRV infection. The multiplex serological system had several advantages: (i) biotinylated protein G allowed us to run both human and animal sera, which is essential because of a lack of XMRV-positive humans; (ii) a novel quality control was a pan-peptide positive-control rabbit serum; and (iii) synthetic XMRV Gag peptides with degenerate positions covering most of the variation of murine leukemia-like viruses did not give higher background than nondegenerate analogs. The principle may be used for creation of variant tolerant peptide serologies. Thus, our system allows rational large-scale serological assays with built-in quality control.

    The influence of self-reported leisure time physical activity and the body mass index on recovery from persistent back pain among men and women: a population-based cohort study.2013In: BMC Public Health, ISSN 1471-2458, E-ISSN 1471-2458, Vol. 13, article id 385Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: There is limited knowledge about leisure time physical activity and the body mass index (BMI) as prognostic factors for recovery from persistent back pain. The aim of this study was to assess the influence of leisure time physical activity and BMI on recovery from persistent back pain among men and women in a general population.

    METHODS: The study population (n=1836) in this longitudinal cohort study consisted of participants reporting persistent back pain in the baseline questionnaire in 2002-2003. Data on leisure time physical activity, BMI and potential confounders were also collected at baseline. Information on recovery from persistent back pain (no back pain periods ≥ 7 days during the last 5 years) was obtained from the follow-up questionnaire in 2007. Log-binomial models were applied to calculate Risk Ratios with 95 percent Confidence Intervals (CI) comparing physically active and normal weight groups versus sedentary and overweight groups.

    RESULTS: Compared to a sedentary leisure time, all measured levels of leisure time physical activity were associated with a greater chance of recovery from persistent back pain among women. The adjusted Risk Ratios was 1.46 (95% CI: 1.06, 2.01) for low leisure time physical activity, 1.51 (95% CI: 1.02, 2.23) for moderate leisure time physical activity, and 1.67 (95% CI: 1.08, 2.58) for high leisure time physical activity. There were no indications that leisure time physical activity influenced recovery among men, or that BMI was associated with recovery from persistent back pain either among men or among women.

    CONCLUSIONS: Regular leisure time physical activity seems to improve recovery from persistent back pain among women.

    Does a healthy lifestyle behaviour influence the prognosis of low back pain among men and women in a general population? A population-based cohort study2014In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 4, no 12, article id e005713Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: To study the influence of healthy lifestyle behaviour on the prognosis of occasional low back pain among men and women in a general population.

    DESIGN: Cohort study with a 4-year follow-up.

    SETTINGS: General population in Stockholm County, Sweden.

    PARTICIPANTS: The study sample comprised 3938 men and 5056 women aged 18-84 from the Stockholm Public Health Cohort reporting occasional low back pain in the baseline questionnaire 2006.

    MEASURES: Lifestyle factors and potential confounders were assessed at baseline. The lifestyle factors smoking habits, alcohol consumption, leisure physical activity and consumption of fruit and vegetables were dichotomised using recommendations for a health-enhancing lifestyle and combined to form the exposure variable 'healthy lifestyle behaviour'. The exposure was categorised into five levels according to the number of healthy lifestyle factors met. The follow-up questionnaire in 2010 gave information about the outcome, long duration troublesome low back pain. Crude and adjusted binomial regression models were applied to estimate the association between the exposure and the outcome analysing men and women separately.

    RESULTS: The risk of developing long duration troublesome low back pain among women with occasional low back pain decreased with increasing healthy lifestyle behaviour (trend test: p=0.006). 21% (28/131) among women with no healthy lifestyle factor (reference) experienced the outcome compared to 9% (36/420) among women with all four factors. Compared to the reference group, the risk was reduced by 35% (RR 0.65, 95% CI 0.44 to 0.96) for women with one healthy lifestyle factor and 52% (RR 0.48, 95% CI 0.31 to 0.77) for women with all four healthy lifestyle factors. There were no clear associations found among men.

    CONCLUSIONS: Healthy lifestyle behaviour seems to decrease the risk of developing long duration troublesome low back pain among women with occasional low back pain and may be recommended to improve the prognosis.

    Predictive models for short-term and long-term improvement in women under physiotherapy for chronic disabling neck pain: a longitudinal cohort study.2019In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 9, no 4, article id e024557Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: To develop predictive models for short-term and long-term clinically important improvement in women with non-specific chronic disabling neck pain during the clinical course of physiotherapy.

    DESIGN: Longitudinal cohort study based on data from a randomised controlled trial evaluating short-term and long-term effects on sensorimotor function over 11 weeks of physiotherapy.

    PARTICIPANTS AND SETTINGS: Eighty-nine women aged 31-65 years with non-specific chronic disabling neck pain from Gävle, Sweden.

    MEASURES: The outcome, clinically important improvement, was measured with the Patient Global Impression of Change Scale (PGICS) and the Neck Disability Index (NDI), assessed by self-administered questionnaires at 3, 9 and 15 months from the start of the interventions (baseline). Twelve baseline prognostic factors were considered in the analyses. The predictive models were built using random-effects logistic regression. The predictive ability of the models was measured by the area under the receiver operating characteristic curve (AUC). Internal validity was assessed with cross-validation using the bootstrap resampling technique.

    RESULTS: Factors included in the final PGICS model were neck disability and age, and in the NDI model, neck disability, depression and catastrophising. In both models, the odds for short-term and long-term improvement increased with higher baseline neck disability, while the odds decreased with increasing age (PGICS model), and with increasing level of depression (NDI model). In the NDI model, higher baseline levels of catastrophising indicated increased odds for short-term improvement and decreased odds for long-term improvement. Both models showed acceptable predictive validity with an AUC of 0.64 (95% CI 0.55 to 0.73) and 0.67 (95% CI 0.59 to 0.75), respectively.

    CONCLUSION: Age, neck disability and psychological factors seem to be important predictors of improvement, and may inform clinical decisions about physiotherapy in women with chronic neck pain. Before using the developed predictive models in clinical practice, however, they should be validated in other populations and tested in clinical settings.

    Prognosis of patients with whiplash-associated disorders consulting physiotherapy: development of a predictive model for recovery2012In: BMC Musculoskeletal Disorders, ISSN 1471-2474, E-ISSN 1471-2474, Vol. 13, article id 264Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Patients with whiplash-associated disorders (WAD) have a generally favourable prognosis, yet some develop longstanding pain and disability. Predicting who will recover from WAD shortly after a traffic collision is very challenging for health care providers such as physical therapists. Therefore, we aimed to develop a prediction model for the recovery of WAD in a cohort of patients who consulted physical therapists within six weeks after the injury.

    METHODS: Our cohort included 680 adult patients with WAD who were injured in Saskatchewan, Canada, between 1997 and 1999. All patients had consulted a physical therapist as a result of the injury. Baseline prognostic factors were collected from an injury questionnaire administered by Saskatchewan Government Insurance. The outcome, global self-perceived recovery, was assessed by telephone interviews six weeks, three and six months later. Twenty-five possible baseline prognostic factors were considered in the analyses. A prediction model was built using Cox regression. The predictive ability of the model was estimated with concordance statistics (c-index). Internal validity was checked using bootstrapping.

    RESULTS: Our final prediction model included: age, number of days to reporting the collision, neck pain intensity, low back pain intensity, pain other than neck and back pain, headache before collision and recovery expectations. The model had an acceptable level of predictive ability with a c-index of 0.68 (95% CI: 0.65, 0.71). Internal validation showed that our model was robust and had a good fit.

    CONCLUSIONS: We developed a model predicting recovery from WAD, in a cohort of patients who consulted physical therapists. Our model has adequate predictive ability. However, to be fully incorporated in clinical practice the model needs to be validated in other populations and tested in clinical settings.

    Concurrent validity of an isokinetic lift test used for admission to the Swedish Armed Forces2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 11, article id e0207054Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to assess the concurrent validity of the IsoKai isokinetic lift test peak force (IsoKaiPeak) in comparison to a submaximal 5-10RM deadlift test (5-10RMDL), and to develop an equation for converting the IsoKaiPeak in Newton (N) to an estimated 1RM (1RMest) deadlift load in kilograms (kg). The participants included 28 males and 16 female employees in the Swedish Armed Forces (20-59 years). Each participant conducted the IsoKai lift test, followed by the 5-10RMDL test at one occasion. The Pearson's correlation coefficient, with a 95% confidence interval was calculated to evaluate the validity between the IsoKaiPeak and the 1RMest deadlift load derived from the 5-10RMDL test. Univariate and multivariable linear regressions were used to derive the equation for calculating the 1RMest deadlift load based on the IsoKaiPeak. The IsoKaiPeak showed good- to-excellent correlation with the 1RMest deadlift weight with a correlation coefficient of 0.84 (0.72-0.91) for the total sample, and 0.65 (0.37-0.83) and 0.81 (0.53-0.93) in males and females, respectively. The final equation, 1RMest deadlift weight (kg) = -51.63 + (0.08 x IsoKaiPeak) + (2.28 x BMI), explained 72% (adjusted R2 = 0.72) of the total variance in the 1RMest, and had a standard error of the estimate (SEE) of 16.57 kg. In conclusion, the IsoKai isokinetic lift test could be considered a highly valid measure of maximal dynamic muscular strength in comparison to the 5-10RMDL. The equation can be used to convert the IsoKai lift test (N) results to an 1RMest deadlift load (kg), but with consideration of the relative large SEE.

    Reliability and agreement of the IsoKai isokinetic lift test - a test used for admission to the Swedish Armed Forces2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 12, article id e0209419Article in journal (Refereed)
    Abstract [en]

    This study was performed to evaluate the reliability and agreement of the IsoKai isokinetic lift test as it is currently administered in admission to the Swedish Armed Forces. The study included an intrarater (n = 534) and interrater reliability sample (n = 137), of Swedish male conscripts who performed the test on two test occasions about two hours apart. Two-to-four lifts were performed at each occasion, and the highest mean (IsoKaiMF) and peak force (IsoKaiPF) produced (N) were used for evaluation. All intraclass coefficients showed excellent reliability. The interrater analyses resulted in intraclass coefficients of 0.942 (95% CI; 0.920-0.959) and 0.858 (95% CI; 0.806-0.896) for the IsoKaiMF and IsoKaiPF, respectively, while the corresponding coefficients for the intrarater analyses were 0.935 (95% CI; 0.923-0.946) and 0.865 (95% CI; 0.842-0.886). Agreement, the capability of a test to detect changes, was assessed by the standard error of measurement (SEM/SEM%) and the smallest real difference (SRD/SRD%). These estimate indicated that it is possible to achieve measurements relevant to use in real practice with the IsoKai isokinetic lift test. Bland and Altman analyses revealed no systematic errors in either sample. Based on these findings, the IsoKai isokinetic lift test is suggested to be a highly reliable test for maximal dynamic muscular strength. The test could be of use in selection procedures in order to accurately evaluate maximal dynamic muscular strength, and for evaluating longitudinal changes in strength.

    Patient-reported outcome and experience measures for diabetes: development of scale models, differences between patient groups and relationships with cardiovascular and diabetes complication risk factors, in a combined registry and survey study in Sweden2018In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 9, no 1, article id e025033Article in journal (Refereed)
    Abstract [en]

    Purpose The Swedish National Diabetes Register (NDR) has developed a diabetes-specific questionnaire to collect information on individuals' management of their diabetes, collaboration with healthcare providers and the disease’s impact on daily life. Our main objective was to develop measures of well-being, abilities to manage diabetes and judgements of diabetes care, and to detect and quantify differences using the NDR questionnaire.

    Design, setting and participants The questionnaire was analysed with using responses from 3689 participants with type 1 and 2 diabetes, randomly sampled from the NDR population, combined with register data on patient characteristics and cardiovascular and diabetes complication risk factors.

    Methods We used item response theory to develop scales for measuring well-being, abilities to manage diabetes and judgements of diabetes care (scores). Test–retest reliability on the scale level was analysed with intraclass correlation. Associations between scores and risk factor levels were investigated with subgroup analyses and correlations.

    Results We obtained scales with satisfactory measurement properties, covering patient reported outcome measures such as general well-being and being free of worries, and patient reported experience measure, for example, access and continuity in diabetes care. All scales had acceptable test–retest reliability and could detect differences between diabetes types, age, gender and treatment subgroups. In several aspects, for example, freedom of worries, type 1 patients report lower than type 2, and younger patients lower than older. Associations were found between some scores and glycated haemoglobin, but none with systolic blood pressure or low-density lipoprotein cholesterol. Clinicians report positive experience of using scores, visually presented, in the patient dialogue.

    Conclusions The questionnaire measures and detects differences in patient well-being, abilities and judgements of diabetes care, and identifies areas for improvement. To further improve diabetes care, we conclude that patient-reported measures are important supplements to cardiovascular and diabetes complication risk factors, reflecting patient experiences of living with diabetes and diabetes care.

    Kvinnors upplevelse av sexuell hälsa efter barnafödande: En kvalitativ metasyntes2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Sexuell hälsa definieras som ett tillstånd av fysiskt, psykiskt, emotionellt och socialt välbefinnande i relation till sexualitet. Att uppnå god sexuell hälsa är viktigt för kvinnors livskvalitet. Barnafödandet innebär en stor omställning i kvinnan och hennes parters liv. Det finns önskemål från kvinnor att samtala mer om den sexuella hälsan med sin barnmorska. Syfte: Syftet med denna studie var att beskriva kvinnors upplevelse av sexuell hälsa efter en förlossning, oavsett förlossningssätt. Metod: Kvalitativ metasyntes med metaetnografisk ansats. Datainsamling utfördes i databaserna CINAHL, PubMed och Web of Science. 15 artiklar kvalitetsgranskades och ingick i metasyntesens resultat. Resultat: Fyra huvudkategorier: Påverkad kroppsuppfattning, Sexuellt umgänge efter förlossning, Barnet i fokus samt Stöd och information. Till dessa följde sex underkategorier: Förändrad självbild, Bröstens tudelade syfte, Tidpunkt för återupptagande, Problem som uppstår, Från barnmorska och annan vårdpersonal och Från närstående. Slutsats: Kvinnors sexuella hälsa påverkas efter barnafödande. Kvinnors fysiska och psykiska mående påverkas, men även relationen till partnern. Kvinnor upplever brist på stöd och information från barnmorskor och annan vårdpersonal. Klinisk tillämpbarhet: Resultatet kan användas för att skapa en ökad förståelse och kunskap hos barnmorskor om vikten av kvinnors sexuella hälsa efter barnafödande.

    Methodology used in studies reporting chronic kidney disease prevalence: a systematic literature review2015In: Nephrology, Dialysis and Transplantation, ISSN 0931-0509, E-ISSN 1460-2385, Vol. 30, no Supp. 4, p. iv6-iv16Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Many publications report the prevalence of chronic kidney disease (CKD) in the general population. Comparisons across studies are hampered as CKD prevalence estimations are influenced by study population characteristics and laboratory methods.

    METHODS: For this systematic review, two researchers independently searched PubMed, MEDLINE and EMBASE to identify all original research articles that were published between 1 January 2003 and 1 November 2014 reporting the prevalence of CKD in the European adult general population. Data on study methodology and reporting of CKD prevalence results were independently extracted by two researchers.

    RESULTS: We identified 82 eligible publications and included 48 publications of individual studies for the data extraction. There was considerable variation in population sample selection. The majority of studies did not report the sampling frame used, and the response ranged from 10 to 87%. With regard to the assessment of kidney function, 67% used a Jaffe assay, whereas 13% used the enzymatic assay for creatinine determination. Isotope dilution mass spectrometry calibration was used in 29%. The CKD-EPI (52%) and MDRD (75%) equations were most often used to estimate glomerular filtration rate (GFR). CKD was defined as estimated GFR (eGFR) <60 mL/min/1.73 m(2) in 92% of studies. Urinary markers of CKD were assessed in 60% of the studies. CKD prevalence was reported by sex and age strata in 54 and 50% of the studies, respectively. In publications with a primary objective of reporting CKD prevalence, 39% reported a 95% confidence interval.

    CONCLUSIONS: The findings from this systematic review showed considerable variation in methods for sampling the general population and assessment of kidney function across studies reporting CKD prevalence. These results are utilized to provide recommendations to help optimize both the design and the reporting of future CKD prevalence studies, which will enhance comparability of study results.

    CKD prevalence varies across the European general population2016In: Journal of the American Society of Nephrology, ISSN 1046-6673, E-ISSN 1533-3450, Vol. 27, no 7, p. 2135-2147Article in journal (Refereed)
    Abstract [en]

    CKD prevalence estimation is central to CKD management and prevention planning at the population level. This study estimated CKD prevalence in the European adult general population and investigated international variation in CKD prevalence by age, sex, and presence of diabetes, hypertension, and obesity. We collected data from 19 general-population studies from 13 European countries. CKD stages 1-5 was defined as eGFR<60 ml/min per 1.73 m(2), as calculated by the CKD-Epidemiology Collaboration equation, or albuminuria >30 mg/g, and CKD stages 3-5 was defined as eGFR<60 ml/min per 1.73 m(2). CKD prevalence was age- and sex-standardized to the population of the 27 Member States of the European Union (EU27). We found considerable differences in both CKD stages 1-5 and CKD stages 3-5 prevalence across European study populations. The adjusted CKD stages 1-5 prevalence varied between 3.31% (95% confidence interval [95% CI], 3.30% to 3.33%) in Norway and 17.3% (95% CI, 16.5% to 18.1%) in northeast Germany. The adjusted CKD stages 3-5 prevalence varied between 1.0% (95% CI, 0.7% to 1.3%) in central Italy and 5.9% (95% CI, 5.2% to 6.6%) in northeast Germany. The variation in CKD prevalence stratified by diabetes, hypertension, and obesity status followed the same pattern as the overall prevalence. In conclusion, this large-scale attempt to carefully characterize CKD prevalence in Europe identified substantial variation in CKD prevalence that appears to be due to factors other than the prevalence of diabetes, hypertension, and obesity.

    Confirmed hypertension and plasma 25(OH)D concentrations amongst elderly men2011In: Journal of Internal Medicine, ISSN 0954-6820, E-ISSN 1365-2796, Vol. 269, no 2, p. 211-218Article in journal (Refereed)
    Abstract [en]

    Objectives. The results of experimental studies suggest that vitamin D deficiency activates the renin-angiotensin system and predisposes to hypertension. Results of previous epidemiological studies investigating the association between 25-hydroxyvitamin D [25(OH)D] status and hypertension have not been consistent, perhaps because of their sole reliance on office blood pressure (BP) measurements leading to some misclassification of hypertension status. No previous studies have examined the association between 25(OH)D status and confirmed hypertension assessed with both office and 24-h BP measurements.

    Design. In this cross-sectional study, we investigated 833 Caucasian men, aged 71 +/- 0.6 years, to determine the association between plasma 25(OH)D concentrations, measured with high-pressure liquid chromatography mass spectrometry, and the prevalence of hypertension. We used both supine office and 24-h BP measurements for classifying participants as normotensive or confirmed hypertensive; participants with inconsistent classifications were excluded.

    Results. In a multivariable adjusted logistic regression model, men with 25(OH)D concentrations < 37.5 nmol L-1 had a 3-fold higher prevalence of confirmed hypertension compared to those with >= 37.5 nmol L-1 25(OH)D (odds ratio = 3.3, 95% CI: 1.0-11.0).

    Conclusions. Our results show that low plasma 25(OH)D concentration is associated with a higher prevalence of confirmed hypertension.

    CUBN is a gene locus for albuminuria2011In: Journal of the American Society of Nephrology, ISSN 1046-6673, E-ISSN 1533-3450, Vol. 22, no 3, p. 555-70Article in journal (Refereed)
    Abstract [en]

    Identification of genetic risk factors for albuminuria may alter strategies for early prevention of CKD progression, particularly among patients with diabetes. Little is known about the influence of common genetic variants on albuminuria in both general and diabetic populations. We performed a meta-analysis of data from 63,153 individuals of European ancestry with genotype information from genome-wide association studies (CKDGen Consortium) and from a large candidate gene study (CARe Consortium) to identify susceptibility loci for the quantitative trait urinary albumin-to-creatinine ratio (UACR) and the clinical diagnosis microalbuminuria. We identified an association between a missense variant (I2984V) in the CUBN gene, which encodes cubilin, and both UACR (P = 1.1 × 10−11) and microalbuminuria (P = 0.001). We observed similar associations among 6981 African Americans in the CARe Consortium. The associations between this variant and both UACR and microalbuminuria were significant in individuals of European ancestry regardless of diabetes status. Finally, this variant associated with a 41% increased risk for the development of persistent microalbuminuria during 20 years of follow-up among 1304 participants with type 1 diabetes in the prospective DCCT/EDIC Study. In summary, we identified a missense CUBN variant that associates with levels of albuminuria in both the general population and in individuals with diabetes

    Official International Association for Therapeutic Drug Monitoring and Toxicology guideline: Development and Validation of Dried Blood Spot-based Methods for Therapeutic Drug Monitoring2019In: Therapeutic Drug Monitoring, ISSN 0163-4356, E-ISSN 1536-3694, Vol. 41, no 4, p. 409-430Article in journal (Refereed)
    Abstract [en]

    Dried blood spot (DBS) analysis has been introduced more and more into clinical practice to facilitate Therapeutic Drug Monitoring (TDM). To assure the quality of bioanalytical methods, the design, development and validation needs to fit the intended use. Current validation requirements, described in guidelines for traditional matrices (blood, plasma, serum), do not cover all necessary aspects of method development, analytical- and clinical validation of DBS assays for TDM. Therefore, this guideline provides parameters required for the validation of quantitative determination of small molecule drugs in DBS using chromatographic methods, and to provide advice on how these can be assessed. In addition, guidance is given on the application of validated methods in a routine context. First, considerations for the method development stage are described covering sample collection procedure, type of filter paper and punch size, sample volume, drying and storage, internal standard incorporation, type of blood used, sample preparation and prevalidation. Second, common parameters regarding analytical validation are described in context of DBS analysis with the addition of DBS-specific parameters, such as volume-, volcano-and hematocrit effects. Third, clinical validation studies are described, including number of clinical samples and patients, comparison of DBS with venous blood, statistical methods and interpretation, spot quality, sampling procedure, duplicates, outliers, automated analysis methods and quality control programs. Lastly, cross-validation is discussed, covering changes made to existing sampling- and analysis methods. This guideline of the International Association of Therapeutic Drug Monitoring and Clinical Toxicology on the development, validation and evaluation of DBS-based methods for the purpose of TDM aims to contribute to high-quality micro sampling methods used in clinical practice.

    Novel and established anthropometric measures and the prediction of incident cardiovascular disease: a cohort study2013In: International Journal of Obesity, ISSN 0307-0565, E-ISSN 1476-5497, Vol. 37, no 12, p. 1579-1585Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: The aim of this study was to compare novel and established anthropometrical measures in their ability to predict cardiovascular disease (CVD), and to determine whether they improve risk prediction beyond classical risk factors in a cohort study of 60-year-old men and women. We also stratified the results according to gender to identify possible differences between men and women. Furthermore, we aimed to replicate our findings in a large independent cohort (The Malmo Diet and Cancer study-cardiovascular cohort).

    METHODS: This was a population-based study of 1751 men and 1990 women, aged 60 years and without CVD at baseline, with 375 incident cases of CVD during 11 years of follow-up. Weight, height, waist circumference (WC), hip circumference and sagittal abdominal diameter (SAD) were measured at baseline. Body mass index (BMI), waist-hip ratio (WHR), waist-hip-height ratio (WHHR), WC-to-height ratio (WCHR) and SAD-to-height ratio (SADHR) were calculated.

    RESULTS: All anthropometric measures predicted CVD in unadjusted Cox regression models per s.d. increment (hazard ratios, 95% confidence interval), while significant associations after adjustments for established risk CVD factors were noted for WHHR 1.20 (1.08-1.33), WHR 1.14 (1.02-1.28), SAD 1.13 (1.02-1.25) and SADHR 1.17 (1.06-1.28). WHHR had higher increases in C-statistics, and model improvements (likelihood ratio tests (P<0.001)). In the replication study (MDC-CC, n = 5180), WHHR was the only measure that improved Cox regression models in men (P = 0.01).

    CONCLUSION: WHHR, a new measure reflecting body fat distribution, showed the highest risk estimates after adjustments for established CVD risk factors. These findings were verified in men but not women in an independent cohort.

    Prediction of cardiovascular disease by abdominal obesity measures is dependent on body weight and sex: results from two community based cohort studies2014In: NMCD. Nutrition Metabolism and Cardiovascular Diseases, ISSN 0939-4753, E-ISSN 1590-3729, Vol. 24, no 8, p. 891-899Article in journal (Refereed)
    Abstract [en]

    AIM: To study waist-hip ratio (WHR), waist circumference (WC), sagittal abdominal diameter (SAD), and waist-hip-height ratio (WHHR) as predictors of CVD, in men and women stratified by BMI (cut-off ≥25).

    METHODS AND RESULTS: A cohort of n = 3741 (53% women) 60-year old individuals without CVD was followed for 11-years (375 CVD cases). To replicate the results, we also assessed another large independent cohort; The Malmö Diet and Cancer study - cardiovascular cohort (MDCC, (n = 5180, 60% women, 602 CVD cases during 16-years). After adjustment for established risk factors in normal-weight women, the hazard ratio (HR) per one standard deviation (SD) were; WHR; 1.91 (95% confidence interval (CI) 1.35-2.70), WC; 1.81 (95% CI 1.02-3.20), SAD; 1.25 (95% CI 0.74-2.11), and WHHR; 1.97 (95% CI 1.40-2.78). In men the association with WHR, WHHR and WC were not significant, whereas SAD was the only measure that significantly predicted CVD in men (HR 1.19 (95% CI 1.04-1.35). After adjustments for established risk factors in overweight/obese women, none of the measures were significantly associated with CVD risk. In men, however, all measures were significant predictors; WHR; 1.24 (955 CI 1.04-1.47), WC 1.19 (95% CI 1.00-1.42), SAD 1.21 (95% CI 1.00-1.46), and WHHR; 1.23 (95% CI 1.05-1.44). Only the findings in men with BMI ≥ 25 were verified in MDCC.

    CONCLUSION: In normal weight individuals, WHHR and WHR were the best predictors in women, whereas SAD was the only independent predictor in men. Among overweight/obese individuals all measures failed to predict CVD in women, whereas WHHR was the strongest predictor after adjustments for CVD risk factors in men.

    Physical activity, obesity and risk of cardiovascular disease in middle-aged men during a median of 30 years of follow-up2016In: European Journal of Preventive Cardiology, ISSN 2047-4873, E-ISSN 2047-4881, Vol. 23, no 4, p. 359-365Article in journal (Refereed)
    Abstract [en]

    Background: We aimed to investigate associations between combinations of body mass index (BMI)-categories, levels of physical activity and long-term risk of cardiovascular disease.

    Method and results: At age 50 years, cardiovascular risk factors were assessed in 2196 participating men of the ULSAM-study. This investigation was repeated at age 60, 70, 77 and 82 years. Being physically active (PA) was defined as three hours of recreational or hard physical training per week. The men were categorized according to BMI/PA-status, as PA/normal weight (n = 593 at baseline), non-PA/normal weight (BMI &lt; 25 kg/m2, n = 580), PA/overweight (n = 418), non-PA/overweight (BMI 25-30 kg/m2, n = 462), PA/obese (n = 62), non-PA/obese (BMI &gt;30 kg/m2, n = 81). We used updated data on BMI and physical activity obtained at all examinations. During follow-up (median 30 years) 850 individuals suffered a cardiovascular disease (myocardial infarction, stroke or heart failure). Using updated data on BMI/PA categories, an increased risk for cardiovascular disease was seen with increasing BMI, but a high physical activity was associated with a lower risk of cardiovascular disease within each BMI category: non-PA/normal weight (hazard ratio (HR) 1.31, 95% confidence interval (CI) 1.04-1.66), PA/overweight (HR 1.52, 95% CI 1.20-1.94), non-PA/overweight (HR 1.65, 95% CI 1.31-2.07) PA/obese (HR 2.05, 95% CI 1.44-2.92) and non-PA/obese (HR 2.39, 95% CI 1.74-3.29), using PA/normal weight men as referent.

    Conclusions: Although physical activity was beneficial at all levels of BMI regarding the risk of future cardiovascular disease, there was still a substantial increased risk associated with being overweight or obese during 30 years of follow-up.

    The association between endostatin and kidney disease and mortality in patients with type 2 diabetes2016In: Diabetes & Metabolism, ISSN 1262-3636, E-ISSN 1878-1780, Vol. 42, no 5, p. 351-357Article in journal (Refereed)
    Abstract [en]

    AIM: Circulating endostatin, a biologically active derivate of collagen XVIII, is considered to be a marker of kidney disease and a risk factor for its related mortality. However, less is known of the role of endostatin in diabetes and the development of diabetic nephropathy. For this reason, our study investigated the associations between circulating endostatin and the prevalence and progression of kidney disease, and its mortality risk in patients with type 2 diabetes (T2D).

    METHODS: This was a cohort study of 607 patients with T2D (mean age: 61 years, 44% women). Estimated glomerular filtration rate (eGFR), calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation, was used to assess the patients' kidney function decline and mortality.

    RESULTS: Of the total study cohort, 20 patients declined by ≥20% in eGFR over 4 years, and 44 died during the follow-up (mean duration: 6.7 years). At baseline, participants with diabetic nephropathy (defined as eGFR<60mL/min/1.73m(2)) and/or microalbuminuria [defined as a urinary albumin-to-creatinine ratio (ACR)>3g/mol] had higher median levels of endostatin than those without nephropathy (62.7μg/L vs 57.4μg/L, respectively; P=0.031). In longitudinal analyses adjusted for age, gender, baseline eGFR and ACR, higher endostatin levels were associated with a higher risk of decline (≥20% in eGFR, OR per 1 SD increase: 1.73, 95% CI: 1.13-2.65) and a higher risk of mortality (HR per 1 SD increase: 1.57, 95% CI: 1.19-2.07).

    CONCLUSION: In patients with T2D, circulating endostatin levels can predict the progression of kidney disease and mortality independently of established kidney disease markers. The clinical usefulness of endostatin as a risk marker in such patients merits further studies.

    Kidney injury molecule (KIM)-1 is associated with insulin resistance: results from two community-based studies of elderly individuals2014In: Diabetes Research and Clinical Practice, ISSN 0168-8227, E-ISSN 1872-8227, Vol. 103, no 3, p. 516-21Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND OBJECTIVES: Insulin resistance has been shown to be closely associated with glomerular filtration rate and urinary albumin/creatinine ratio, even prior to the development of diabetes. Urinary kidney injury molecule 1 (KIM-1) is a novel, highly specific marker of kidney tubular damage. The role of insulin resistance in the development of kidney tubular damage is not previously reported. Thus, we aimed to investigate the associations between insulin sensitivity (assessed by HOMA) and urinary KIM-1.

    DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: Two community-based cohorts of elderly individuals were investigated: Prospective Investigation of the vasculature in Uppsala seniors (PIVUS, n=701; mean age 75 years, 52% women); and Uppsala Longitudinal Study of adult men (ULSAM, n=533; mean age 78 years).

    RESULTS: Lower insulin sensitivity was associated with higher urinary KIM-1 in both cohorts after adjustments for age, BMI, blood pressure, antihypertensive treatment, glomerular filtration rate, and urinary albumin-creatinine ratio (PIVUS: regression coefficient for 1-SD higher HOMA-IR 0.11, 95% CI 0.03-0.20, p=0.009, and ULSAM: 0.13, 95% CI 0.04-0.22, p=0.007). Results were similar in individuals without diabetes, with normal kidney function and normo-albuminuria.

    CONCLUSIONS: Our findings in elderly individuals support the notion that the interplay between an impaired glucose metabolism and renal tubular damage is evident even prior to the development of diabetes and overt kidney disease.

    Endostatin, cathepsin S, and cathepsin L, and their association with inflammatory markers and mortality in patients undergoing hemodialysis2015In: Blood Purification, ISSN 0253-5068, E-ISSN 1421-9735, Vol. 39, no 4, p. 259-265Article in journal (Refereed)
    Abstract [en]

    Background/Aims: Although both endostatin and cathepsins S have been associated with higher mortality, data in patients with end-stage renal disease (ESRD) are scarce.

    Methods: A longitudinal cohort study of 207 prevalent patients undergoing hemodialysis.

    Results: Cathepsins S and L were associated with soluble receptors for tumor necrosis factor (sTNFR1 and sTNFR2, rho between 0.28 and 0.43, p < 0.001 for all). Weaker or absent associations between endostatin, cathepsins S and L were seen with other inflammatory biomarkers, that is, CRP, interleukin 6, pentraxin 3, and TNF. In Cox and Laplace regression models adjusted for age, sex, dialysis vintage, and diabetes: standard deviation increments of endostatin was associated with a lower mortality (hazard ratio 0.75, 95% confidence interval (CI) 0.57-0.98), and with 6.8 months longer median survival.

    Conclusions: The high levels of endostatin, cathepsins S and L, and their associations with sTNFR1 and sTNFR2 warrant further studies exploring mortality, and the angiogenic and inflammatory pathways in ESRD. (C) 2015 S. Karger AG, Basel

    High levels of soluble tumor necrosis factor receptors 1 and 2 and their association with mortality in patients undergoing hemodialysis2015In: CardioRenal Medicine, ISSN 1664-3828, Vol. 5, no 2, p. 89-95Article in journal (Refereed)
    Abstract [en]

    Objective: Circulating soluble tumor necrosis factor receptors 1 and 2 (sTNFR1 and 5TNFR2) are associated with chronic kidney disease (CKD) progression in patients with CKD or diabetes, and with higher mortality. However, data in patients with end-stage renal disease are scarce. Therefore, we analyzed serum levels of sTNFR1 and sTNFR2 and investigated their association with inflammatory markers and mortality in dialysis patients. Research Design and Methods: This was a longitudinal cohort study of 207 prevalent patients (median age 66 years, 56% men) undergoing hemodialysis in Stockholm, Sweden. Demographics, clinical characteristics, including comorbidities and laboratory data, were obtained at baseline, together with prospective follow-up for mortality.

    Results: The median sTNFR1 and sTNFR2 levels were 17,680 ng/l [95% confidence interval (CI) 17,023-18,337] and 24,450 ng/l (95% CI 23,721-25,179), respectively. During a follow-up of 31 months (interquartile range, 21-38), 77 patients died. There was no association between the levels of sTNFRs and mortality in Cox regression models, and no consistent trend towards higher or lower mortality was seen in Laplace regression models. sTNFR1 and sTNFR2 levels were highly associated with other inflammatory markers including interleukin-6, pentraxin 3 and TNF-alpha. Conclusions:Prevalent hemodialysis patients have several-fold higher levels of sTNFRs compared to previous studies in CKD stage 4 patients. As no consistent association between TNFR and mortality was observed, clinical implications of measuring these receptors to predict outcome end-stage renal disease patients provide limited results.

    Use of proteomics to investigate kidney function decline over 5 years2017In: American Society of Nephrology. Clinical Journal, ISSN 1555-9041, E-ISSN 1555-905X, Vol. 12, no 8, p. 1226-1235Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND OBJECTIVES: Using a discovery/replication approach, we investigated associations between a multiplex panel of 80 circulating proteins associated with cardiovascular pathology or inflammation, and eGFR decline per year and CKD incidence.

    DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We used two cohorts, the Prospective Investigation of the Vasculature in Uppsala Seniors Study (PIVUS; n=687, mean age of 70 years, 51% women) and the Uppsala Longitudinal Study of Adult Men (ULSAM; n=360 men, mean age of 78 years), with 5-year follow-up data on eGFR. There were 231 and 206 incident cases of CKD during follow-up in the PIVUS and ULSAM studies, respectively. Proteomic profiling of 80 proteins was assessed by a multiplex assay (proximity extension assay). The assay uses two antibodies for each protein and a PCR step to achieve a high-specific binding and the possibility to measure multiple proteins in parallel, but gives no absolute concentrations.

    RESULTS: In the discovery cohort from the PIVUS Study, 28 plasma proteins were significantly associated with eGFR decline per year, taking into account the multiple testing. Twenty of these proteins were significantly associated with eGFR decline per year in the replication cohort from the ULSAM Study after adjustment for age, sex, cardiovascular risk factors, medications, and urinary albumin-to-creatinine ratio (in order of significance: TNF-related apoptosis-inducing ligand receptor 2*, CD40L receptor, TNF receptor 1*, placenta growth factor*, thrombomodulin*, urokinase plasminogen activator surface receptor*, growth/differentiation factor 15*, macrophage colony-stimulating factor 1, fatty acid-binding protein*, cathepsin D, resistin, kallikrein 11*, C-C motif chemokine 3, proteinase-activated receptor 1*, cathepsin L, chitinase 3-like protein 1, TNF receptor 2*, fibroblast growth factor 23*, monocyte chemotactic protein 1, and kallikrein 6). Moreover, 11 of the proteins predicted CKD incidence (marked with * above). No protein consistently predicted eGFR decline per year independently of baseline eGFR in both cohorts.

    CONCLUSIONS: Several circulating proteins involved in phosphate homeostasis, inflammation, apoptosis, extracellular matrix remodeling, angiogenesis, and endothelial dysfunction were associated with worsening kidney function. Multiplex proteomics appears to be a promising way of discovering novel aspects of kidney disease pathology.

    Levels of soluble tumor necrosis factor receptor 1 and 2, gender, and risk of myocardial infarction in Northern Sweden2018In: Atherosclerosis, ISSN 0021-9150, E-ISSN 1879-1484, Vol. 272, p. 41-46Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND AIMS: Soluble receptors for tumor necrosis factor alpha (sTNFR1 and sTNFR2) have been associated with cardiovascular diseases, and some evidence points towards a difference in associated risk between men and women. We aimed to study the association between sTNFR1 and sTNFR2 and incident myocardial infarctions (MI) and to explore the influence of established cardiovascular risk factors in men and women.

    METHODS: We conducted a nested case control study in three large Swedish cohorts, including 533 myocardial infarction cases, and 1003 age-, sex- and cohort-matched controls. Odds ratios (OR) with 95% confidence intervals (CI) were calculated.

    RESULTS: An association between circulating sTNFR1 and sTNFR2 and an increased risk for MI was found when comparing cases and controls. The odds ratios were significant after adjustment for established cardiovascular risk factors and C-reactive protein in women (OR 1.44, 95% CI 1.08-1.93 for TNFR1, and 1.61, 95% CI 1.11-2.34 for TNFR2), but was abolished in men. Women with a combination of elevated CRP and values in the upper quartile of TNFR1 or TNFR2 had a 5-fold higher risk of myocardial infarction versus those with normal CRP and values in the lower three quartiles of TNFR1 or TNFR2.

    CONCLUSIONS: As the risk estimates for TNFR1 and TNFR2 were higher and remained significant after adjustments for established cardiovascular risk factors in women but not in men, a potential role for TNFR1 and TNFR2 in identifying women with a higher MI risk is possible. The future clinical role of TNFR1 and TNFR2 in combination with CRP to identify high risk patients for coronary heart disease has yet to be determined.

    Soluble tumor necrosis factor receptor 1 (sTNFR1) is associated with increased total mortality due to cancer and cardiovascular causes: findings from two community based cohorts of elderly2014In: Atherosclerosis, ISSN 0021-9150, E-ISSN 1879-1484, Vol. 237, no 1, p. 236-242Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Experimental evidence support soluble receptors for tumor necrosis factor alpha as important mediators of the underlying pathology leading to cardiovascular disease and cancer. However, prospective data concerning the relation between circulating soluble tumor necrosis factor receptor-1 (sTNFR1) and mortality in humans are lacking. We aimed to explore and validate the association between sTNFR1 and mortality, and to explore the influence of other established risk factors for mortality, including other inflammatory markers.

    METHODS: The association between serum sTNFR1and the risk for mortality was investigated in two community-based cohorts of elderly: the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS; women 50%, n = 1005, mean age 70 years, median follow-up 7.9 years) and the Uppsala Longitudinal Study of Adult Men (ULSAM, n = 775, mean age 77 years, median follow-up 8.1 years).

    RESULTS: In total, 101 participants in PIVUS and 274 in ULSAM died during follow-up. In multivariable Cox regression models adjusted for inflammation, lifestyle and established cardiovascular risk factors, one standard deviation (SD) higher sTNFR1 was associated with a hazard ratio (HR) for mortality of 1.37, 95% confidence interval (CI) 1.17-1.60, in PIVUS and HR 1.22, 95% CI 1.10-1.37 in ULSAM. Moreover, circulatingsTNFR1 was associated with cardiovascular mortality (HR per SD of sTNFR1, 1.24, 95% CI 1.07-1.44) and cancer mortality (HR per SD of sTNFR1, 1.32, 95% CI 1.11-1.57) in the ULSAM cohort. High levels of sTNFR1 identified individuals with increased risk of mortality among those with high as well as low levels of systemic inflammation.

    CONCLUSIONS: An association between circulating sTNFR1 and an increased risk for mortality was found and validated in two independent community-based cohorts. The future clinical role of sTNFR1 to identify high risk patients for adverse outcomes and mortality has yet to be determined.

    Urinary kidney injury molecule-1 and the risk of cardiovascular mortality in elderly men2014In: American Society of Nephrology. Clinical Journal, ISSN 1555-9041, E-ISSN 1555-905X, Vol. 9, no 8, p. 1393-1401Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND OBJECTIVES: Kidney injury molecule-1 (KIM-1) has been suggested as a clinically relevant highly specific biomarker of acute kidney tubular damage. However, community-based data on the association between urinary levels of KIM-1 and the risk for cardiovascular mortality are lacking. This study aimed to investigate the association between urinary KIM-1 and cardiovascular mortality.DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This was a prospective study, using the community-based Uppsala Longitudinal Study of Adult Men (N=590; mean age 77 years; baseline period, 1997-2001; median follow-up 8.1 years; end of follow-up, 2008).RESULTS: During follow-up, 89 participants died of cardiovascular causes (incidence rate, 2.07 per 100 person-years at risk). Models were adjusted for cardiovascular risk factors (age, systolic BP, diabetes, smoking, body mass index, total cholesterol, HDL cholesterol, antihypertensive treatment, lipid-lowering treatment, aspirin treatment, and history of cardiovascular disease) and for markers of kidney dysfunction and damage (cystatin C-based eGFR and urinary albumin/creatinine ratio). Higher urinary KIM-1/creatinine (from 24-hour urine collections) was associated with a higher risk for cardiovascular mortality (hazard ratio per SD increase, 1.27; 95% confidence interval [95% CI], 1.05 to 1.54; P=0.01). Participants with a combination of high KIM-1/creatinine (upper quintile, ≥175 ng/mmol), low eGFR (≤60 ml/min per 1.73 m(2)), and microalbuminuria/macroalbuminuria (albumin/creatinine ratio≥3 g/mol) had a >8-fold increased risk compared with participants with low KIM-1/creatinine (<175 ng/mmol), normal eGFR (>60 ml/min per 1.73 m(2)), and normoalbuminuria (albumin/creatinine ratio<3 g/mol) (hazard ratio, 8.56; 95% CI, 4.17 to 17.56; P<0.001).CONCLUSIONS: These findings suggest that higher urinary KIM-1 may predispose to a higher risk of cardiovascular mortality independently of established cardiovascular risk factors, eGFR, and albuminuria. Additional studies are needed to further assess the utility of measuring KIM-1 in the clinical setting.

    Urinary kidney injury molecule 1 and incidence of heart failure in elderly men2013In: European Journal of Heart Failure, ISSN 1388-9842, E-ISSN 1879-0844, Vol. 15, no 4, p. 447-446Article in journal (Refereed)
    Abstract [en]

    AIMS: There is growing recognition of the clinical importance of cardiorenal syndrome-the bidirectional interplay between kidney and cardiac dysfunction. Yet, the role of kidney tubular damage in the development of heart failure is less studied. The objective of this study was to investigate whether urinary kidney injury molecule (KIM)-1, a specific marker of tubular damage, predisposes to an increased heart failure risk.

    METHODS AND RESULTS: This was a community-based cohort study [Uppsala Longitudinal study of Adult Men (ULSAM)] of 565, 77-year-old men free from heart failure at baseline. Heart failure hospitalizations were used as outcome. During follow-up (median 8.0 years), 73 participants were hospitalized for heart failure. In models adjusted for cardiovascular risk factors (age, systolic blood pressure, diabetes, smoking, body mass index, LDL/HDL ratio, antihypertensive treatment, lipid-lowering treatment, aspirin treatment, LV hypertrophy, and prevalent cardiovascular disease) and markers of kidney dysfunction and damage [cystatin C-based glomerular filtration rate (GFR) and urinary albumin/creatinine ratio], a higher urinary KIM-1/creatinine ratio was associated with higher risk for heart failure (hazard ratio upper vs. lower tertile, 1.81; 95% confidence interval 1.01-3.29; P < 0.05). Participants with a combination of low GFR (<60 mL/min/1.72 m(2)) and high KIM-1/creatinine (>128 ng/mmol) had a 3-fold increase in heart failure risk compared with participants with normal GFR and KIM-1 (P < 0.001).

    CONCLUSION: Our findings suggest that kidney tubular damage predisposes to an increased risk for heart failure in the community. Further studies are needed to clarify the causal role of KIM-1 in the development of heart failure, and to evaluate the clinical utility of urinary KIM-1 measurements.
