    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

    Finishing the euchromatic sequence of the human genome

    The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

    Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

    In an analysis of 31,717 cancer cases and 26,136 cancer-free controls from 13 genome-wide association studies, we observed large chromosomal abnormalities in a subset of clones in DNA obtained from blood or buccal samples. We observed mosaic abnormalities, either aneuploidy or copy-neutral loss of heterozygosity, of >2 Mb in size in autosomes of 517 individuals (0.89%), with abnormal cell proportions of between 7% and 95%. In cancer-free individuals, frequency increased with age, from 0.23% under 50 years to 1.91% between 75 and 79 years (P = 4.8 × 10(-8)). Mosaic abnormalities were more frequent in individuals with solid tumors (0.97% versus 0.74% in cancer-free individuals; odds ratio (OR) = 1.25; P = 0.016), with stronger association with cases who had DNA collected before diagnosis or treatment (OR = 1.45; P = 0.0005). Detectable mosaicism was also more common in individuals for whom DNA was collected at least 1 year before diagnosis with leukemia compared to cancer-free individuals (OR = 35.4; P = 3.8 × 10(-11)). These findings underscore the time-dependent nature of somatic events in the etiology of cancer and potentially other late-onset diseases

    Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

    What is the effect of VPOR not being regulated in the Plan and Building Act and what challenges do this entrail?

    I 2007 brukte Oslo kommune for første gang verktøyet «Veiledende plan for offentlig rom (VPOR)», som en del av «Oslomodellen». VPOR er ikke forankret juridisk i plan- og bygningsloven, men legger likevel føringer for arealbruk tidlig i planprosessen. Denne masteroppgaven tar for seg noen utfordringer ved at Plan- og bygningsetaten i Oslo benytter seg av strategiske planer som VPOR. Ved å studere deler av prosessen for arealplanlegging i Oslo kommune skal dette belyses ved å stille opp en problemstilling. For å danne et bilde av den betydning det har å bruke strategiske planer som VPOR har det blitt hentet inn informasjon, foretatt intervjuer og dokumentanalyser. Denne informasjonen er deretter vurdert opp mot relevant teori og rettspraksis. Graden av fleksibilitet som ligger i arealplanleggingen er blitt utfordret i Oslo de seneste årene. En årsak er den raske byutviklingen (de Vibe, 2015). Denne analysen ser på hvordan Plan- og bygningsetaten har utviklet VPOR som et virkemiddel med større fleksibilitet for å håndtere den sterke byutviklingen på prosess-siden. Gjennom analysen og drøftingen har flere temaer vært oppe for diskusjon. Noen av disse temaene er saksbehandlingsregler, kostnadsberegning og forhåndsbinding. Gjennom hele oppgaven vurderes spørsmålet om mangel på virkemiddel burde vært løftet opp som et lovgiver-spørsmål. Likevel ser vi nytten av at Plan- og bygningsetaten utfordrer dette rommet, ved å ha løst det på prosess-siden. I tillegg drøfter oppgaven positive og negative sider ved eventuell lovfesting av VPOR i plan- og bygningsloven. Legitimitet, fleksibilitet, effektivitet og demokrati er hensyn og prinsipper som kan stå imot hverandre og som vurderes i oppgaven. Om VPOR bør bli lovfestet eller ikke, avhenger av hvordan den implementeres i Plan- og bygningsloven. Oppgaven gir eksempler på hvordan dette kan gjøres.In 2007, the municipality of Oslo introduced for the first time its «Veiledende plan for offentlige rom (VPOR)» as part of the so-called «Oslo model». VPOR is not legally connected to the Planning and Building Act, but still applies requirements for land use early in the planning process. This master thesis addresses some challenges in connection with the Oslo Planning and Building Agency’s use of strategic plans such as VPOR. By studying parts of the area planning process in Oslo municipality, the issue is highlighted. In order to form a picture of the importance of using strategic plans such as VPOR, information has been gathered, interviews made and documents have been analysed. Our findings have been assessed against relevant theory and case law. In recent years, the degree of flexibility in area planning in Oslo has been challenged. An important reason is the rapid urban development. The analysis looks at how the Planning and Building Agency has developed VPOR as a tool with greater flexibility to handle the process of strong urban development. The Planning and Building Agency has solved the challenge of lack of tools on the process side. Through our analysis and discussion, it is considered if the lack of remedies should be a question for the legislator. Nevertheless, we see the benefit that the Planning and Building Agency challenges this space by solving it on the process side. Through the analysis and discussion, several topics have been discussed. Some of these are case processing rules, cost calculation and pre-binding. Throughout the study, the question is considered whether a lack of instrument should have been lifted as a legislator's question (at legislator level). Nevertheless, we see the benefit in the Planning and Building Agency challenging this shortcoming by solving it on the process stage. In addition, the document discusses positive and negative aspects of possible statutory rights of VPOR in the National Planning and Building Act. Legitimacy, flexibility, efficiency and democracy are considerations and principles that can stand against each other and are therefore discussed. Whether VPOR should be statutory or not, depends on how it may be implemented in the Planning and Building Act. Our study gives examples of how this could be done.M-EUT
