Linking meta-omics to the kinetics of denitrification intermediates unveils pH-dependent factors behind N2O emissions and also nitrite build up in earth.
While the growth in altruistic and compliant prosocial behaviors was stagnant, there was an increase in anonymous prosocial behaviors and a decrease in public and dire prosocial behaviors. Emotional behaviors did not linearly change, though slightly tapered off by the final time points. Parallel process latent growth curve model results indicated positive correlations between the slopes of cultural integration and most forms of prosocial behaviors. These findings highlight the positive role of cultural integration as an acculturative process for U.S. Latinx youth and the multidimensionality of prosocial behaviors.Aims Physical activity has consistently been shown to improve cardiovascular health and high-density lipoprotein-cholesterol levels. However, only small and heterogeneous studies have investigated the effect of exercise on high-density lipoprotein functions. Our aim is to evaluate, in the largest observational study to date, the association between leisure time physical activity and a range of high-density lipoprotein functional traits. Methods The study sample consisted of 296 Spanish adults at high cardiovascular risk. Usual leisure time physical activity and eight measures of high-density lipoprotein functionality were averaged over two measurements, one year apart. Gefitinib datasheet Multivariable linear regression models were used to explore the association between leisure time physical activity (exposure) and each high-density lipoprotein functional trait (outcome), adjusted for cardiovascular risk factors. Results Higher levels of leisure time physical activity were positively and linearly associated with average levels ein functionality, namely cholesterol efflux capacity, the capacity of high-density lipoprotein to esterify cholesterol and paraoxonase-1 antioxidant activity in individuals free of diabetes and lower cholesteryl ester transfer protein activity in individuals with type 2 diabetes.Background Environmental pollution and weather changes unfavorably impact on cardiovascular disease. However, limited research has focused on ST-elevation myocardial infarction (STEMI), the most severe yet distinctive form of acute coronary syndrome. Methods and results We appraised the impact of environmental and weather changes on the incidence of STEMI, analysing the bivariate and multivariable association between several environmental and atmospheric parameters and the daily incidence of STEMI in two large Italian urban areas. Specifically, we appraised carbon monoxide (CO), nitrogen dioxide (NO2), nitric oxide (NOX), ozone, particulate matter smaller than 10 μm (PM10) and than 2.5 μm (PM2.5), temperature, atmospheric pressure, humidity and rainfall. A total of 4285 days at risk were appraised, with 3473 cases of STEMI. Specifically, no STEMI occurred in 1920 (44.8%) days, whereas one or more occurred in the remaining 2365 (55.2%) days. Multilevel modelling identified several pollution and weather predictors of STEMI. In particular, concentrations of CO (p=0.024), NOX (p=0.039), ozone (p=0.003), PM10 (p=0.033) and PM2.5 (p=0.042) predicted STEMI as early as three days before the event, as well as subsequently, and NO predicted STEMI one day before (p = 0.010), as well as on the same day. A similar predictive role was evident for temperature and atmospheric pressure (all p less then 0.05). Conclusions The risk of STEMI is strongly associated with pollution and weather features. While causation cannot yet be proven, environmental and weather changes could be exploited to predict STEMI risk in the following days.Aims Obesity is related to better prognosis in heart failure with either reduced (HFrEF; left ventricular ejection fraction (LVEF) less then 40%) or preserved LVEF (HFpEF; LVEF ≥50%). Whether the obesity paradox exists in patients with heart failure and mid-range LVEF (HFmrEF; LVEF 40-49%) and whether it is independent of heart failure aetiology is unknown. Therefore, we aimed to test the prognostic value of body mass index (BMI) in ischaemic and non-ischaemic heart failure patients across the whole spectrum of LVEF. Methods Consecutive ambulatory heart failure patients were enrolled in two tertiary centres in Italy and Spain and classified as HFrEF, HFmrEF or HFpEF, of either ischaemic or non-ischaemic aetiology. Patients were stratified into underweight (BMI less then 18.5 kg/m2), normal-weight (BMI 18.5-24.9 kg/m2), overweight (BMI 25-29.9 kg/m2), mild-obese (BMI 30-34.9 kg/m2), moderate-obese (BMI 35-39.9 kg/m2) and severe-obese (BMI ≥40 kg/m2) and followed up for the end-point of five-year all-cause mortality. Results We enrolled 5155 patients (age 70 years (60-77); 71% males; LVEF 35% (27-45); 63% HFrEF, 18% HFmrEF, 19% HFpEF). At multivariable analysis, mild obesity was independently associated with a lower risk of all-cause mortality in HFrEF (hazard ratio, 0.78 (95% confidence interval (CI) 0.64-0.95), p = 0.020), HFmrEF (hazard ratio 0.63 (95% CI 0.41-0.96), p = 0.029), and HFpEF (hazard ratio 0.60 (95% CI 0.42-0.88), p = 0.008). Both overweight and mild-to-moderate obesity were associated with better outcome in non-ischaemic heart failure, but not in ischaemic heart failure. Conclusions Mild obesity is independently associated with better survival in heart failure across the whole spectrum of LVEF. Prognostic benefit of obesity is maintained only in non-ischaemic heart failure.Aims Ischaemic heart disease is classically associated with coronary artery disease. Recent evidences showed the correlation between coronary microvascular dysfunction and ischaemic heart disease, even independently of coronary artery disease. Ion channels represent the final effectors of blood flow regulation mechanisms and their genetic variants, in particular of Kir6.2 subunit of the ATP-sensitive potassium channel (KATP), are reported to be involved in ischaemic heart disease susceptibility. The aim of the present study is to evaluate the role of KATP channel and its genetic variants in patients with ischaemic heart disease and evaluate whether differences exist between coronary artery disease and coronary microvascular dysfunction. Methods A total of 603 consecutive patients with indication for coronary angiography due to suspected myocardial ischaemia were enrolled. Patients were divided into three groups coronary artery disease (G1), coronary microvascular dysfunction (G2) and normal coronary arteries (G3).
