- Background: Heart failure (HF) may complicate acute coronary syndrome (ACS) and is associ-ated with a high burden of short-and long-term morbidity and mortality. Only limited data regarding future ischemic events and rehospitalization are available for patients who suffer HF before or during ACS.Methods: A secondary analysis of 4 large ACS trials (PLATO, APPRAISE-2, TRACER, and TRIL-OGY ACS) using Cox proportional hazards models was performed to investigate the associa-tion of HF status (no HF, chronic HF, de novo HF) at presentation for ACS with all-cause and cardiovascular death, major adverse cardiovascular event (MACE ), myocardial infarction, stroke, and hospitalization for heart failure (HHF) by 1 year. Cumulative incidence plots are presented at 30 days and 1 year.Results: A total of 11.1% of the 47,474 patients presenting with ACS presented with evidence of acute HF, 55.0% of whom presented with de novo HF. Patients with chronic HF presented with evidence of acute HF at a higher rate than those with no previous HF (40.3% vs 6.9%). Compared to those without HF, those with chronic and de novo HF had higher rates of all-cause mortality (adjusted hazard ratio [aHR] 2.01, 95% confidence interval [CI] 1.72-2.34 and aHR 1.47, 95% CI1.15-1.88, respectively), MACE (aHR 1.47, 95% CI1.31-1-.66 and aHR 1.38, 95% CI1.12-1.69), and HHF (aHR 2.29, 95% CI2.02-2.61 and aHR 1.48, 95% CI 1.20-1.82) at 1 year.Conclusion: In this large cohort of patients with ACS, both prior and de novo HF complicating ACS were associated with significantly higher risk-adjusted rates of death, ischemic events and HHF at 30 days and 1 year. Further studies examining the association between HF and out-comes in this high-risk population are warranted, especially given the advent of more contem-porary HF therapies.

- A trend toward greater body size in dizygotic (DZ) than in monozygotic (MZ) twins has been suggested by some but not all studies, and this difference may also vary by age. We analyzed zygosity differences in mean values and variances of height and body mass index (BMI) among male and female twins from infancy to old age. Data were derived from an international database of 54 twin cohorts participating in the COllaborative project of Development of Anthropometrical measures in Twins (CODATwins), and included 842,951 height and BMI measurements from twins aged 1 to 102 years. The results showed that DZ twins were consistently taller than MZ twins, with differences of up to 2.0 cm in childhood and adolescence and up to 0.9 cm in adulthood. Similarly, a greater mean BMI of up to 0.3 kg/m(2) in childhood and adolescence and up to 0.2 kg/m(2) in adulthood was observed in DZ twins, although the pattern was less consistent. DZ twins presented up to 1.7% greater height and 1.9% greater BMI than MZ twins; these percentage differences were largest in middle and late childhood and decreased with age in both sexes. The variance of height was similar in MZ and DZ twins at most ages. In contrast, the variance of BMI was significantly higher in DZ than in MZ twins, particularly in childhood. In conclusion, DZ twins were generally taller and had greater BMI than MZ twins, but the differences decreased with age in both sexes.

Tidskriftsartikel (refereegranskat)abstract
- This commentary highlights two cross-cultural issues identified from our global mental health (GMH) research, RECOLLECT (Recovery Colleges Characterisation and Testing) 2: self-enhancement and ingroup biases. Self-enhancement is a tendency to maintain and express unrealistically positive self-views. Ingroup biases are differences in one’s evaluation of others belonging to the same social group. These biases are discussed in the context of GMH research using self-report measures across cultures. GMH, a field evolving since its Lancet series introduction in 2007, aims to advance mental health equity and human rights. Despite a 16.5-fold increase in annual GMH studies from 2007 to 2016, cross-cultural understanding remains underdeveloped. We discuss the impact of individualism versus collectivism on self-enhancement and ingroup biases. GMH research using concepts, outcomes, and methods aligned with individualism may give advantages to people and services oriented to individualism. GMH research needs to address these biases arising from cross-cultural differences to achieve its aim.

- Retinal angiogenesis is tightly regulated to meet oxygenation and nutritional requirements. In diseases such as proliferative diabetic retinopathy and neovascular age-related macular degeneration, uncontrolled angiogenesis can lead to blindness. Our goal is to better understand the molecular processes controlling retinal angiogenesis and discover novel drugs that inhibit retinal neovascularisation. Phenotype-based chemical screens were performed using the ChemBridge Diverset™ library and inhibition of hyaloid vessel angiogenesis in Tg(fli1:EGFP) zebrafish. 2-[(E)-2-(Quinolin-2-yl)vinyl]phenol (quininib) robustly inhibits developmental angiogenesis at 4-10 µM in zebrafish and significantly inhibits angiogenic tubule formation in HMEC-1 cells, angiogenic sprouting in aortic ring explants and retinal revascularisation in OIR mice. Quininib is well tolerated in zebrafish, human cell lines and murine eyes. Profiling screens of 153 angiogenic and inflammatory targets revealed quininib does not directly target VEGF receptors but antagonises cysteinyl leukotriene receptor 1 and 2 (CysLT1-2) at micromolar IC50 values. In summary, quininib is a novel anti-angiogenic small molecule CysLT receptor antagonist. Quininib inhibits angiogenesis in a range of cell and tissue systems, revealing novel physiological roles for CysLT signalling. Quininib has potential as a novel therapeutic to treat ocular neovascular pathologies and may complement current anti-VEGF biologicals.

- Whether monozygotic (MZ) and dizygotic (DZ) twins differ from each other in a variety of phenotypes is important for genetic twin modeling and for inferences made from twin studies in general. We analyzed whether there were differences in individual, maternal and paternal education between MZ and DZ twins in a large pooled dataset. Information was gathered on individual education for 218,362 adult twins from 27 twin cohorts (53% females; 39% MZ twins), and on maternal and paternal education for 147,315 and 143,056 twins respectively, from 28 twin cohorts (52% females; 38% MZ twins). Together, we had information on individual or parental education from 42 twin cohorts representing 19 countries. The original education classifications were transformed to education years and analyzed using linear regression models. Overall, MZ males had 0.26 (95% CI [0.21, 0.31]) years and MZ females 0.17 (95% CI [0.12, 0.21]) years longer education than DZ twins. The zygosity difference became smaller in more recent birth cohorts for both males and females. Parental education was somewhat longer for fathers of DZ twins in cohorts born in 1990-1999 (0.16 years, 95% CI [0.08, 0.25]) and 2000 or later (0.11 years, 95% CI [0.00, 0.22]), compared with fathers of MZ twins. The results show that the years of both individual and parental education are largely similar in MZ and DZ twins. We suggest that the socio-economic differences between MZ and DZ twins are so small that inferences based upon genetic modeling of twin data are not affected.

- For over 100 years, the genetics of human anthropometric traits has attracted scientific interest. In particular, height and body mass index (BMI, calculated as kg/m2) have been under intensive genetic research. However, it is still largely unknown whether and how heritability estimates vary between human populations. Opportunities to address this question have increased recently because of the establishment of many new twin cohorts and the increasing accumulation of data in established twin cohorts. We started a new research project to analyze systematically (1) the variation of heritability estimates of height, BMI and their trajectories over the life course between birth cohorts, ethnicities and countries, and (2) to study the effects of birth-related factors, education and smoking on these anthropometric traits and whether these effects vary between twin cohorts. We identified 67 twin projects, including both monozygotic (MZ) and dizygotic (DZ) twins, using various sources. We asked for individual level data on height and weight including repeated measurements, birth related traits, background variables, education and smoking. By the end of 2014, 48 projects participated. Together, we have 893,458 height and weight measures (52% females) from 434,723 twin individuals, including 201,192 complete twin pairs (40% monozygotic, 40% same-sex dizygotic and 20% opposite-sex dizygotic) representing 22 countries. This project demonstrates that large-scale international twin studies are feasible and can promote the use of existing data for novel research purposes.

- To identify circulating proteins influencing Coronavirus Disease 2019 (COVID-19) susceptibility and severity, we undertook a two-sample Mendelian randomization (MR) study, rapidly scanning hundreds of circulating proteins while reducing bias due to reverse causation and confounding. In up to 14,134 cases and 1.2 million controls, we found that an s.d. increase in OAS1 levels was associated with reduced COVID-19 death or ventilation (odds ratio (OR) = 0.54, P = 7 × 10−8), hospitalization (OR = 0.61, P = 8 × 10−8) and susceptibility (OR = 0.78, P = 8 × 10−6). Measuring OAS1 levels in 504 individuals, we found that higher plasma OAS1 levels in a non-infectious state were associated with reduced COVID-19 susceptibility and severity. Further analyses suggested that a Neanderthal isoform of OAS1 in individuals of European ancestry affords this protection. Thus, evidence from MR and a case–control study support a protective role for OAS1 in COVID-19 adverse outcomes. Available pharmacological agents that increase OAS1 levels could be prioritized for drug development.
