- Perturbation in the expression and signaling pathways of vascular endothelial growth factor (VEGF) has been linked to pathogenesis of hematologic malignancies. We investigated the expression and clinical importance of VEGF and two of its receptors, VEGFR-1 and VEGFR-2, in childhood precursor B-cell acute lymphoblastic leukemia (pre-B ALL) by using immunohistochemistry. These angiogenic proteins were expressed in the majority of leukemic bone marrow samples. Notably, pre-B ALL patients had significantly increased expression of VEGFR-1 compared with no expression in the nonmalignant group, indicating a link between VEGFR-1 protein expression and pre-B ALL. These novel findings suggest that VEGFR-1 may have clinical importance in childhood pre-B ALL.

- OBJECTIVE: The primary aim of this study was to systematically compare perceived sleep quality, sleeplessness behavior, sense of mastery, self-esteem, depression, subjective health, and effects of sleep loss in men and women with stable coronary artery disease (CAD). Further aims were to determine possible predictors of poor sleep quality and sense of mastery, as well as the consequences of too little sleep. METHODS: Comparative-correlation and predictive design were used. Patients with a history of stable angina pectoris scheduled to undergo coronary angiography at Linköping University Hospital in Sweden were included. There were 47 women and 88 men (mean age 62.4 years) with CAD. Structured interviews using validated questionnaires covered sleep quality and sleep habits, effects of sleep loss, psychologic resources, and depression. RESULTS: Multiple stepwise regression analysis showed that sleeplessness behavior, depressed mood, female gender, and pharmacologic treatments with inflammation inhibitors significantly (P < .0001) accounted for the variance of poorer sleep quality. The analysis also showed that the following factors in descending order significantly accounted (P < .0001) for the outcome of sleep quality: inability to feel refreshed by sleep, difficulty in maintaining sleep, gastrointestinal problems, too little sleep, final morning awakening time, sleep onset latency, lying down because of daytime tiredness, and daytime physical tiredness. CONCLUSIONS: Compared with men, women with stable CAD may be especially at risk of experiencing poor sleep quality, even when sleeplessness behavior and pharmacologic treatments with inflammation inhibitors are controlled. It is also possible that they may be more at risk of depressed mood. Copyright © 2006 by Mosby, Inc.

- Aim: Research focusing on hyperarousability in association with general sensitivity to stress has increased. This study aimed to: (i) describe values for self-reported hyperarousal behaviour traits, depression, sleeplessness behaviour and health-related quality of life [The Short Form 36 Health Survey Questionnaire (SF-36)] in a gender-stratified random sample from the Swedish population, and (ii) test the validity and reliability of the Swedish version of the Hyperarousal Behavioural Trait Scale (H-scale). Methods: In this study, 402 women and 391 men from Sweden were included. A test-retest study was performed on 297 subjects. Results: The total mean score on the H-scale was 29.5 (SD 10.0, 95% CI 28.8-30.2). Compared to men, women scored higher on the H-scale (total score, sub-scales and many items), whereas no evidence of an age trend was seen. The H-scale has proven to be a valid and reliable scale. Pearson's correlation coefficient showed similar magnitude and direction between the H-scale and the Zung's Self-rating Depression Scale, as between the H-scale and the Vicious Cycle of Sleeplessness Behaviour Scale, Vitality, Mental Health and the Mental Component Summary index on the SF-36 respectively. The Cronbach's alpha for the H-scale was 0.84 and estimated stability test-retest point of time varies between 0.73 and 0.80. Conclusions: This study indicates gender differences in response style in association with altered health-related quality of life. The H-scale is a valid and reliable self-reported scale for measuring hyperarousal behavioural trait research outcome in clinical practice. © 2006 Nordic College of Caring Science.

- Introduction: Previous studies have examined the relationship between initiation sleep difficulties and quality of life. However, when reviewing the literature in this area we found no reports of a relationship between evening physical activity and health related quality of life in patients with coronary disease. This study was designed to investigate assumed sleep, circadian rhythm, evening physical activity and health related quality of life.Methods: Twenty-six men and 21 women, mean age 64.0 (SD 8.9) years and 63 (SD 9.3) years, respectively, with stable angina pectoris were included. For assessment of health related quality of life the patients completed the SF36 questionnaire. The data were compared with those for men and women in the general Swedish population. Physical activity was continuously recorded at home, using actigraphy with an integral light recorder (Model AW-L, Cambridge Neurotechnology Ltd, UK) in 1-minute epochs during one week. The data were downloaded by Actiwatch Reader and imported to the Actiwatch software for Windows 98.Results: Average time of going to bed was 22.37, sleep latency 27 minutes, assumed sleep duration 7.59 hr, time in bed 8.56 hr and sleep efficiency 79.2%. No differences were found during the seven nights. Nonparametric analysis of the circadian rhythm showed that 39 of 47 patients had the lowest 5-hour count activity onset at 00.00 p.m. and 41of 47 patients had the maximal 10 hr count onset 08.00 a.m. or later. Sleep analysis indicated reduced activity in the evening (p.m. 06.00-09.00). Some actigraphic parameters of the evening activity associated significantly with circadian rhythm parameters. Compared to the general Swedish population, the patients ́ health related quality of life waspoor. Linear stepwise regression analysis showed that reduced activity 3 evenings/week significantly explained health related quality of life in32.3% of role function outcome, due to physical causes (p=0.0001) and in 24.7% (p<0.01) of social function, whereas reduced activity 2 evenings/week explained 20% (p<0.01) of body pain.Conclusions: These data indicate that sleep-activity profile is associated with health related quality of life in patients with stable angina pectoris.

Tidskriftsartikel (refereegranskat)abstract
- Nutrient loading and climate change affect coastal ecosystems worldwide. Unravelling the combined effects of these pressures on benthic macrofauna is essential for understanding the future functioning of coastal ecosystems, as it is an important component linking the benthic and pelagic realms. In this study, we extended an existing model of benthic macrofauna coupled with a physical-biogeochemical model of the Baltic Sea to study the combined effects of changing nutrient loads and climate on biomass and metabolism of benthic macrofauna historically and in scenarios for the future. Based on a statistical comparison with a large validation dataset of measured biomasses, the model showed good or reasonable performance across the different basins and depth strata in the model area. In scenarios with decreasing nutrient loads according to the Baltic Sea Action Plan but also with continued recent loads (mean loads 2012-2014), overall macrofaunal biomass and carbon processing were projected to decrease significantly by the end of the century despite improved oxygen conditions at the seafloor. Climate change led to intensified pelagic recycling of primary production and reduced export of particulate organic carbon to the seafloor with negative effects on macrofaunal biomass. In the high nutrient load scenario, representing the highest recorded historical loads, climate change counteracted the effects of increased productivity leading to a hyperbolic response: biomass and carbon processing increased up to mid-21st century but then decreased, giving almost no net change by the end of the 21st century compared to present. The study shows that benthic responses to environmental change are nonlinear and partly decoupled from pelagic responses and indicates that benthic-pelagic coupling might be weaker in a warmer and less eutrophic sea.

- PTEN and SHP1 are tumor suppressor genes involved in the regulation of cell cycle control and apoptosis. The authors investigated the protein expression of PTEN and SHP1, by immunohistochemistry in tissue microarrays from bone marrow samples in children, diagnosed with acute lymphoblastic leukaemia and nonmalignant controls. PTEN was overexpressed in diagnostic ALL samples, while SHP1 showed a low expression. Both proteins showed a significant difference in expression compared to nonmalignant controls. The roles of PTEN and SHP1 are not well investigated in pediatric leukemia and could in the future play a role as prognostic factors.

Identifying Patterns of Emotional and Behavioural Problems in Preschool children : Facilitating Early Detection
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Mental health problems often debut in early childhood and may last throughout adulthood, thereby making early detection and intervention especially important. The overarching aim of the present thesis was to identify patterns of emotional and behavioural problems indicating mental health problems in preschool children. To facilitate the detection of such problems early on, one available screening instrument Strengths and Difficulties Questionnaire (SDQ), was validated. The development and interaction of externalising problems in preschool children were studied over time. Functioning and behaviour and their relations to protective and risk indicators in both environmental and personal characteristics were explored. The long-term goal was to increase knowledge about early identification of emotional and behavioural problems in preschool children in order to facilitate early intervention.In Study I (n=690), the subscales Hyperactivity and Conduct Problems were shown to be valid for children in the age group 1–3 years. A reasonable level of validity was found for the age group 4–5 years when using the original SDQ four-factor solution. The preschool teachers considered most of the SDQ items relevant and possible to rate. Based on the results of Study II (n=815), a score of ≥12 on the SDQ Total Problems Scale is recommended as a cut-off for Swedish preschool children. There were significant differences between boys and girls on all subscales except for the Emotional subscale. The Swedish norms for SDQ are to a large extent similar to findings from other European countries. Study III (n=195) showed that preschool children’s conduct problems decrease over time. Children exhibiting more initial hyperactivity (at year 1) have less reduction in conduct problems over time, i.e. the more hyperactivity early in life, the more conduct problems at year 3. In Study IV (n=197), children high in engagement and social interaction function well over time, even in the presence of hyperactivity, while children with low engagement and interaction alone or in combination with hyperactivity and conduct problems continue to have problems. Stability was related to the existence of a larger number of protective or risk indicators respectively.Taken together, this thesis has shown that the SDQ can be used to identify preschool children at risk of developing mental health problems later in life.

Tidskriftsartikel (refereegranskat)abstract
- Cardiovascular disease is a common cause of morbidity and premature mortality. Cardiovascular disease can be prevented when risk factors are identified early. Calcified carotid artery atheromas (CCAAs), detected in panoramic radiographs, and periodontitis have both been associated with increased risk of cardiovascular disease. This case-control study aimed to 1) investigate associations between periodontitis and CCAA detected in panoramic radiographs and 2) determine the risk of future myocardial infarctions due to CCAA combined with periodontitis. We evaluated 1,482 participants (738 cases and 744 controls) with periodontitis and CCAAs recruited from the PAROKRANK study (Periodontitis and Its Relation to Coronary Artery Disease). Participants were examined with panoramic radiographs, including the carotid regions. Associations between myocardial infarction and periodontitis combined with CCAA were evaluated in 696 cases and 696 age-, sex-, and residential area-matched controls. Periodontitis was evaluated radiographically (as degree of bone loss) and with a clinical periodontal disease index score (from clinical and radiographic assessments). We found associations between CCAA and clinical periodontal disease index score among cases (odds ratio [OR], 1.51; 95% CI, 1.09 to 2.10; P = 0.02) and controls (OR, 1.70; 95% CI, 1.22 to 2.38; P < 0.01), although not between CCAA and the degree of bone loss. In a multivariable model, myocardial infarction was associated with CCAA combined with periodontitis, as assessed by degree of bone loss (OR, 1.75; 95% CI, 1.11 to 2.74; P = 0.01). When the cohort was stratified by sex, only men showed a significant association between myocardial infarction and CCAA combined with periodontitis. Participants with clinically diagnosed periodontitis exhibited CCAA in panoramic radiographs more often than those without periodontitis, irrespective of the presence of a recent myocardial infarction. Participants with combined periodontitis and CCAA had a higher risk of having had myocardial infarction as compared with participants with either condition alone. These findings implied that patients in dental care might benefit from dentists assessing panoramic radiographs for CCAA-particularly, patients with periodontitis who have not received any preventive measures for cardiovascular disease.

Läkaren, döden och brottet : Studier i den svenska rättsmedicinens etablering
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This dissertation investigates the long historical process leading up to the establishment of Swedish forensic medicine in the middle of the 19th century. Both the development of the practice of investigating suspicious deaths, primarily through autopsies, and the scientific development, leading up to the founding of forensic medicine as a medical discipline and a distinct field of knowledge are dealt with. The focus of the study is primarily on the historical process itself, its phases, continuities and discontinuities. The theoretical framework is based on three analytical concepts: medicalization, professionalization and institutionalization. Special attention is also paid to the characteristics of forensic medicine, its position between the law and the medicine, and the consequences this had on its scientific development. The first analytical chapter of the dissertation investigates the oldest medico-legal activities on Swedish ground, with emphasis on the 17th and 18th centuries. In the following chapters the main focus is on the transition period between the older medico-legal activities and the 19th century forensic medicine, an analytical distinction used throughout the dissertation, and the institutionalization of forensic medicine as a teaching subject. The dissertation also includes an historical reconstruction of different aspects of the autopsy practice. Autopsies are viewed as physical operations and a special kind of sign reading, situated between the old semiotic model and the new diagnostic method of the 19th century. In the last chapter the process leading up to the foundation of a distinct forensic field of knowledge in Sweden is studied.

Fuktsäkra byggnader : en nulägesbeskrivning
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Boverket ser ett behov av en kunskapssammanställning kring nuläget om fuktsäkra byggnader i Sverige för att ha en så bred och korrekt förståelse som möjligt för vem branschen är, vilka regler som tillämpas, var det finns kunskapscentra och vilka utvecklingsbehov som behöver stödjas för att branschen ska kunna ta större ansvar. De utmaningar som noteras är: Byggsektorn beredskap och förmåga att möta de nya förändrade byggregler som planeras av Boverket.Den stora andelen fuktrelaterade fel och skador som rapporteras i olika utredningar. Kraven kopplat till fuktrelaterade innemiljöproblem är otydliga och ofta svåra att följa upp. Detta kan leda till fuktrelaterade innemiljöproblem som orsakar lidande för de individer som drabbas.Miljö och klimatfrågan ställer krav både på resurseffektivitet och minskad klimatpåverkan samt resiliens och klimatanpassning. Förändrade boendevanor och brukarvanor som ändrar på förutsättningarna i en byggnad. Fragmentering och specialisering med många aktörer med ansvar för sin del endast. Några utvecklingsområden har noterats. Områden där det behövs både forskning och utveckling av teknik, processer och samarbeten: Kvalitetssäkring av nya material, konstruktioner och produktionsmetoderKompetensutveckling och kompetensspridning.Framtagning och tillgängliggörande av kunskap, teknikutveckling. Samsyn behöver utvecklas när det gäller bl.a. uttorkning i betong och i vilken omfattning byggnader behöver skyddas mot fukt under byggproduktionen. Undersökning av utvecklingsmöjligheter behövs för att ta vara på digitaliseringens möjligheter med sensorer, digitala tvillingar, AI m.m. i samband med fuktsäkerhet. Kartläggningen skulle förstärkas med en bredare internationell utblick. Det tycks finnas en del skillnader både i arbetssätt och erfarenheter kring fuktsäkra byggnader.Förhoppningen är att kartläggning av fuktsäkra byggnader ska bidra till kunskapsspridning om bransch, aktörer, teknik, system, konstruktion, kontroller, drift och underhåll samt forskning och fortsatt utvecklingsarbete.

- A framework is needed for identifying internal and external factors essential for the nursing management of psychological supportive health care and education for patients' self-care in sleep. In order to generate more knowledge from the patient's perspective, the aim of this study was to describe how patients with coronary artery disease (CAD) perceive that their sleep is influenced by rest, activity and health in outpatient care. Qualitative interviews were performed with 33 outpatients. The data were analysed using a phenomenographic method. Three descriptive categories of the phenomenon were described: my lifestyle is reflected in my sleep behaviour, handling the practices around tiredness and sleep, and feelings of negative and positive efficacy. Feelings of tiredness, fatigue and sleepiness were different pre-sleep stages, but were also related to the patient's adaptation and recovery. Creating one's own personal time and feelings of efficacy gave an inner sense of strength which is indicated as being particularly important in managing stress and the demands of everyday life in a satisfactory manner. From a contextual, holistic perspective on health, it is important to identify the patient's needs, symptoms and intentional or unintentional self-care management strategies regarding sleep and lifestyle. To promote a positive health outcome it is essential to identify sleeplessness behaviour and perceived self-efficacy for self-care in sleep. © 2007 Nordic College of Caring Science.

- Aim. To evaluate whether there are gender differences in insomnia, sleep quality, sleep efficiency (%), general arousal, disease-specific and health-related quality of life in patients with coronary artery disease, compared with an age- and gender-matched randomly selected group from the general population. Background. There are gender difference effects of sleep disturbances in the general population, but this perspective among patients with coronary artery disease has been poorly analysed. Design. In this prospective study, comparative, descriptive and model testing designs were used. Method. The patients with coronary artery disease, 556 men and 324 women aged 25–86, were compared with a matched population-based group. Data were collected by validated and reliability-tested questionnaires. Results. The prevalence of severe insomnia varied between 17–44% in all four groups. The severe insomniac coronary artery disease patients displayed a two- or threefold higher presleep arousal, had two hours shorter nocturnal sleep duration/night and were more limited in their physical exercise level than the population-based group. Gender differences in sleep quality, sleep efficiency (%) and general arousal disappeared with increased insomnia severity. Conclusions. Independent of gender, age and comorbidity, physical exercise, general arousal behaviour and delayed poststress recovery after mental stress were found to have a negative impact on the coronary artery disease patients’ sleep quality and sleep efficiency (%), interfering with their health-related quality of life. The variables significantly explained 41% of the sleep quality outcome and 29% of the sleep efficiency (%). Relevance to clinical practice. Insomnia because of hyperarousal behaviour can be an important factor in the development of an individual self-care management programme supported by a healthcare team.

Guidelines for the use and interpretation of assays for monitoring autophagy

Forskningsöversikt (refereegranskat)abstract
- In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.

Tidskriftsartikel (refereegranskat)abstract
- Background: The duration of colonization with methicillin-resistant Staphylococcus aureus (MRSA) is not well known and there is debate as to whether a patient colonized with MRSA ever can be defined as 'MRSA-negative'. Methods: Since 2003 all notified MRSA cases have been systematically followed in Skane County, southern Sweden. Cultures are taken from the nares, throat, perineum and possible skin lesions. Contact tracing is conducted. The screening program continues as long as cultures are positive and then until 1 y of consecutive negative cultures for MRSA is completed. Results: Of the 578 MRSA cases during 2003-2006, 535 were included in this retrospective study. The median duration of colonization with MRSA was 5.9 months. Having household contacts with MRSA, young age, spa-type t002 and colonization in 2 or more locations, were significantly associated with a longer duration of colonization. Having a clinical infection treated with antibiotics (compared to clinical infection with no antibiotic treatment or asymptomatic carriage) was significantly associated with a shorter carriage time. Eradication treatment was associated with a shorter carriage time. Conclusion: These results may have implications for the management of patients with MRSA carriage. The study indicates that MRSA carriage can be defined as 'negative' in a follow-up program and shows the importance of performing contact tracing among household members.

Tidskriftsartikel (refereegranskat)abstract
- Eradication of methicillin-resistant Staphylococcus aureus (MRSA) colonisation may prevent transmission of strains between patients and reduces the risk of clinical infection. Colonisation of the throat is associated with prolonged carriage and is more difficult to eradicate. An open randomised study was conducted to evaluate two eradication protocols. Patients with pharyngeal carriage of MRSA were enrolled at six Swedish centres during 4 years. One treatment group received oral rifampicin and either clindamycin or trimethoprim/sulfamethoxazole (SXT) for 7 days in combination with nasal mupirocin. Patients in the other group were treated with nasal mupirocin only. Patients in the same household were randomised together. Both groups followed a hygiene protocol including chlorhexidine washing. Cultures from the nares, perineum and throat were taken at baseline and then at 2 weeks, 2 months and 6 months after the end of treatment. A total of 28 patients received rifampicin-based systemic antibiotics and 24 subjects received mupirocin only. At follow-up 6 months after the end of treatment, 61% of patients and 50% of households in the systemic antibiotics group had culture results negative for MRSA. Significantly less patients (12%) and households (10%) became decolonised in the group receiving topical treatment only. A combination of rifampicin and either clindamycin or SXT was more effective in eliminating pharyngeal MRSA carriage compared with topical treatment with mupirocin only.

- Obesity is heritable and predisposes to many diseases. To understand the genetic basis of obesity better, here we conduct a genome-wide association study and Metabochip meta-analysis of body mass index (BMI), a measure commonly used to define obesity and assess adiposity, in up to 339,224 individuals. This analysis identifies 97 BMI-associated loci (P < 5 × 10(-8)), 56 of which are novel. Five loci demonstrate clear evidence of several independent association signals, and many loci have significant effects on other metabolic phenotypes. The 97 loci account for ∼2.7% of BMI variation, and genome-wide estimates suggest that common variation accounts for >20% of BMI variation. Pathway analyses provide strong support for a role of the central nervous system in obesity susceptibility and implicate new genes and pathways, including those related to synaptic function, glutamate signalling, insulin secretion/action, energy metabolism, lipid biology and adipogenesis.

- Background: Cancer patients often show no or only modest benefit from a given therapy. This major problem in oncology is generally attributed to the lack of specific predictive biomarkers, yet a global measure of cancer cell activity may support a comprehensive mechanistic understanding of therapy efficacy. We reasoned that network analysis of omic data could help to achieve this goal. Methods: A measure of "cancer network activity" (CNA) was implemented based on a previously defined network feature of communicability. The network nodes and edges corresponded to human proteins and experimentally identified interactions, respectively. The edges were weighted proportionally to the expression of the genes encoding for the corresponding proteins and relative to the number of direct interactors. The gene expression data corresponded to the basal conditions of 595 human cancer cell lines. Therapeutic responses corresponded to the impairment of cell viability measured by the half maximal inhibitory concentration (IC50) of 130 drugs approved or under clinical development. Gene ontology, signaling pathway, and transcription factor-binding annotations were taken from public repositories. Predicted synergies were assessed by determining the viability of four breast cancer cell lines and by applying two different analytical methods. Results: The effects of drug classes were associated with CNAs formed by different cell lines. CNAs also differentiate target families and effector pathways. Proteins that occupy a central position in the network largely contribute to CNA. Known key cancer-associated biological processes, signaling pathways, and master regulators also contribute to CNA. Moreover, the major cancer drivers frequently mediate CNA and therapeutic differences. Cell-based assays centered on these differences and using uncorrelated drug effects reveals novel synergistic combinations for the treatment of breast cancer dependent on PI3K-mTOR signaling. Conclusions: Cancer therapeutic responses can be predicted on the basis of a systems-level analysis of molecular interactions and gene expression. Fundamental cancer processes, pathways, and drivers contribute to this feature, which can also be exploited to predict precise synergistic drug combinations.

- Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms.
