- AIMS: To evaluate the association of cardiovascular health (CVH), measured by Life's Essential 8 score, with the risk of premature mortality and to determine the patterns of CVH-related differences in life expectancy among people with and without type 2 diabetes (T2D).MATERIALS AND METHODS: This prospective study included 309,789 participants (age 56.6 ± 8.1 years; 46% men) enroled in the UK Biobank. The Life's Essential 8 composite measure consists of four health behaviours (diet, physical activity, nicotine exposure, and sleep) and four health factors (BMI, non-HDL cholesterol, blood glucose, and blood pressure), and the maximum CVH score was 100 points. CVH was categorised into low, moderate, and high groups. Premature death was defined as death before the age of 75. Cox proportional hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated, and life expectancy was estimated.RESULTS: During a median follow-up of 12.7 years, 13,683 cases of premature death were documented. Compared to participants with low CVH, the multivariable HRs (95% CIs) of premature death were 0.59 (0.56-0.62) and 0.42 (0.39-0.45) for the moderate and high CVH groups, respectively. This association was stronger in participants with T2D compared with those without T2D. At the age of 50 years, compared to low CVH groups, high CVH was associated with a gain of 9.79 (9.70-9.87) and 5.58 (5.48-5.67) additional life years for men with and without T2D, respectively. The corresponding life gain for women with and without T2D was 24.21 (24.13-24.27) and 10.18 (10.10-10.27), respectively.CONCLUSIONS: Maintaining an ideal Life's Essential 8 score may provide more benefits for people with T2D than for those without T2D, including a lower risk of premature death and an increased lifespan.

- Background and aims:To investigate the associations of ideal cardiovascular health metrics (ICVHMs) with all-cause mortality among former and current smokers compared with never smokers.Methods and results:A total of 378,147 participants [mean age (SD) years: 56.3 (8.1); 47.2 % men] were included from the UK Biobank cohort. The ICVHMs were combined Life's simple 7 from the American Heart Association and sleep duration time. The association was explored using COX regression models. During a median follow-up of 13.3 years, we documented 24,594 deaths. Compared with never smokers, among former smokers, the multivariable-adjusted hazard ratio (HR) for all-cause mortality was 1.82 (95%CI 1.71-1.92) for participants who had <= 2 ICVHMs and 1.03 (0.97-1.10) for participants who had >= 6 ICVHMs; among current smokers, the HRs for mortality were 2.74 (2.60-2.89) and 2.18 (1.78-2.67). The phenomenon was more pronounced among participants younger than 60 years [HR (95%CI), 1.82 (1.71-1.95) for <= 2 ICVHMs vs 1.04 (0.96-1.12) for >= 6 ICVHMs with age >= 60 years and 1.83 (1.62-2.06) vs 0.98 (0.88-1.11) with age <60 years among former smokers; 2.66 (2.49-2.85) vs 2.44 (1.84-3.24) with age >= 60 years and 2.85 (2.62-3.10) vs 1.96 (1.47-2.61) with age <60 years among current smokers]. In addition, the HR for mortality of each 1-number increment in ICVHMs was 0.87 (0.86-0.89) among former smokers and 0.91 (0.89-0.94) among current smokers.Conclusion:Our findings indicated the importance of adherence to have more ICVHMs in the mortality risk among former smokers, and priority of smoking cessation in current smokers.

- BACKGROUND: An association between sweetened beverages and several cardiometabolic diseases has been reported, but their association with atrial fibrillation (AF) is unclear. We aimed to investigate the associations between consumption of sugar-sweetened beverages (SSB), artificially sweetened beverages (ASB), and pure fruit juice (PJ) and risk of consumption with AF risk and further evaluate whether genetic susceptibility modifies these associations.METHODS:A total of 201 856 participants who were free of baseline AF, had genetic data available, and completed a 24-hour diet questionnaire were included. Cox proportional hazard models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs).RESULTS: During a median follow-up of 9.9 years, 9362 incident AF cases were documented. Compared with nonconsumers, individuals who consumed >2 L/wk of SSB or ASB had an increased risk of AF (HR, 1.10 [95% CI, 1.01-1.20] and HR, 1.20 [95% CI, 1.10-1.31]) in the multivariable-adjusted model. A negative association was observed between the consumption of ≤ 1 L/wk of PJ and the risk of AF (HR, 0.92 [95% CI, 0.87-0.97]). The highest HRs (95% CIs) of AF were observed for participants at high genetic risk who consumed >2 L/wk of ASB (HR, 3.51 [95% CI, 2.94-4.19]), and the lowest HR were observed for those at low genetic risk who consumed ≤ 1 L/wk of PJ (HR, 0.77 [95% CI, 0.65-0.92]). No significant interactions were observed between the consumption of SSB, ASB, or PJ and genetic predisposition to AF.CONCLUSIONS: Consumption of SSB and ASB at >2 L/wk was associated with an increased risk for AF. PJ consumption ≤ 1 L/wk was associated with a modestly lower risk for AF. The association between sweetened beverages and AF risk persisted after adjustment for genetic susceptibility to AF. This study does not demonstrate that consumption of SSB and ASB alters AF risk but rather that the consumption of SSB and ASB may predict AF risk beyond traditional risk factors.

- BackgroundSodium-glucose cotransporter 2 (SGLT2) inhibitors have shown promise in reducing the risk of atrial fibrillation (AF). However, the results are controversial and the underlying metabolic mechanism remains unclear. Emerging evidence implied that SGLT2 inhibitors have extra beneficial metabolic effects on circulating metabolites beyond glucose control, which might play a role in reducing the risk of AF. Hence, our study aimed to investigate the effect of circulating metabolites mediating SGLT2 inhibition in AF by Mendelian randomization (MR).MethodsA two-sample and two-step MR study was conducted to evaluate the association of SGLT2 inhibition with AF and the mediation effects of circulating metabolites linking SGLT2 inhibition with AF. Genetic instruments for SGLT2 inhibition were identified as genetic variants, which were both associated with the expression of SLC5A2 gene and glycated hemoglobin level (HbA1c). Positive control analysis on type 2 diabetes mellitus (T2DM) was conducted to validate the selection of genetic instruments.ResultsGenetically predicted SGLT2 inhibition (per 1 SD decrement in HbA1c) was associated with reduced risk of T2DM (odds ratio [OR] = 0.63 [95% CI 0.45, 0.88], P = 0.006) and AF (0.51 [0.27, 0.97], P = 0.039). Among 168 circulating metabolites, two metabolites were both associated with SGLT2 inhibition and AF. The effect of SGLT2 inhibition on AF through the total concentration of lipoprotein particles (0.88 [0.81, 0.96], P = 0.004) and the concentration of HDL particles (0.89 [0.82, 0.97], P = 0.005), with a mediated proportion of 8.03% (95% CI [1.20%, 14.34%], P = 0.010) and 7.59% ([1.09%, 13.34%], P = 0.011) of the total effect, respectively.ConclusionsThis study supported the association of SGLT2 inhibition with a reduced risk of AF. The total concentration of lipoprotein particles and particularly the concentration of HDL particles might mediate this association. Further mechanistic and clinical studies research are needed to understand the mediation effects of circulating metabolites especially blood lipids in the association between SGLT2 inhibition and AF.

- AIMS: Recent studies have demonstrated the associations of the consumption of different beverages with cardiometabolic diseases, whereas no studies have investigated such associations in heart failure (HF). Thus, this study aimed to explore the associations of the consumption of sugar-sweetened beverages (SSBs), artificially sweetened beverages (ASBs), and pure fruit/vegetable juices (PJs) with the risk of incident HF.METHODS AND RESULTS: This prospective cohort study included 209 829 participants in the UK Biobank who completed at least one 24-h diet questionnaire and who were free of baseline HF. Cox proportional hazard models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs). During a median follow-up of 9.9 years, 4328 incident HF cases were recorded. Compared to corresponding non-consumers, individuals who consumed >2 L/week SSBs or ASBs had an increased risk of HF (HR: 1.22, 95% CI: 1.08-1.38 and HR: 1.30, 95% CI: 1.16-1.47, respectively) in the multivariate adjusted model. An inverse association was observed between the consumption of >0-1 L/week PJs and the risk of HF (HR, 0.90; 95% CI, 0.83-0.98). Additionally, a significant interaction was observed between PJ consumption and sleep duration on HF risk (P for interaction = 0.030).CONCLUSIONS: Increased consumption of SSBs or ASBs may be an independent risk factor for HF, whereas moderate intake of PJs may have a protective effect on HF.

- ObjectiveWe aimed to test the associations of sugar-sweetened beverages (SSB), artificially sweetened beverages (ASB), and pure fruit juice (PJ) consumption with the risk of nonalcoholic fatty liver disease (NAFLD).MethodsData for 136 277 UK Biobank participants who completed the dietary questionnaire and did not have a history of liver disease were included. Logistic regression was used for the cross-sectional setting where NAFLD was defined by a fatty liver index (FLI) ≥60. Cox proportional hazard regression was used for the longitudinal setting where hospitalized NAFLD was defined as hospital admission with Internationl Classification of Diseases-10 codes K76.0 and K75.8.ResultsCompared with 0 L/wk for corresponding beverages, multivariate-adjusted odds ratios (95% confidence intervals) for NAFLD in consumption ≤1, 1 to 2, and >2 L/wk were 1.06 (1.02-1.10), 1.24 (1.19-1.29), and 1.42 (1.35-1.49) for SSB; 1.43 (1.37-1.50), 1.73 (1.65-1.82), and 2.37 (2.25-2.50) for ASB, and 0.87 (0.84-0.89), 0.91 (0.88-0.94), and 1.07 (1.02-1.13) for PJ, respectively. Consumption of SSB and ASB were both positively correlated with FLI (P for line < .001). During a median follow-up of 10.2 years, 1043 cases of hospitalized NAFLD were recorded. ASB consumption of 1 to 2 and >2 L/wk was associated with a 22% (0.99-1.50) and 35% (1.11-1.65) increased risk of hospitalized NAFLD, respectively (P for trend = .002). However, the associations of SSB and PJ with the risk of hospitalized NAFLD were not significant.ConclusionsConsumption of SSB, ASB, and PJ were all related to the risk of NAFLD. Excessive consumption of ASBs was associated with an increased risk of incident hospitalized NAFLD.

- Although significant improvements have been achieved for organic photovoltaic cells (OPVs), the top-performing devices still show power conversion efficiencies far behind those of commercialized solar cells. One of the main reasons is the large driving force required for separating electron-hole pairs. Here, we demonstrate an efficiency of 14.7% in the single-junction OPV by using a new polymer donor PTO2 and a nonfullerene acceptor IT-4F. The device possesses an efficient charge generation at a low driving force. Ultrafast transient absorption measurements probe the formation of loosely bound charge pairs with extended lifetime that impedes the recombination of charge carriers in the blend. The theoretical studies reveal that the molecular electrostatic potential (ESP) between PTO2 and IT-4F is large, and the induced intermolecular electric field may assist the charge generation. The results suggest OPVs have the potential for further improvement by judicious modulation of ESP.

- Revealing the charge generation is a crucial step to understand the organic photovoltaics. Recent development in non-fullerene organic solar cells (OSCs) indicates efficient charge separation even with negligible energetic offset between the donor and acceptor materials. These new findings trigger a critical question concerning the charge separation mechanism in OSCs, traditionally believed to result from sufficient energetic offset between the polymer donor and fullerene acceptor. We propose a new mechanism, which involves the molecular electrostatic potential, to explain efficient charge separation in non-fullerene OSCs. Together with the new mechanism, we demonstrate a record efficiency of similar to 12% for systems with negligible energetic offset between donor and acceptor materials. Our analysis also rationalizes different requirement of the energetic offset between fullerene-based and non-fullerene OSCs, and paves the way for further design of OSC materials with both high photocurrent and high photovoltage at the same time.

- BackgroundLimited studies have explored the association between visceral adipose tissue (VAT) mass and fat-to-muscle mass ratio (FMR) and mortality. We aimed to evaluate the sex-specific association of VAT and FMR with all-cause and cause-specific mortality by age. MethodsA total of 438 896 participants (49.8% men, mean age +/- standard deviation: 57 +/- 8 years for men; 56 +/- 8 years for women) were included from the UK Biobank cohort. The nature of VAT was predictive, as obtained by sex-stratified, non-linear prediction models. Fat and muscle mass were estimated using a bioelectrical impedance assessment device. FMR was calculated as the fat mass divided by the muscle mass in the whole body. VAT and FMRs were divided into quintiles in ascending order, and the 3rd quintile was used as the reference. Cox regression analyses were used to estimate the associations between VAT, FMR and mortality. ResultsDuring a median of 12.4 years of follow-up, we documented 29 903 deaths. After adjusting for various covariates, the individuals in the highest quintiles of VAT and FMR had the highest hazard ratios (HRs) of all-cause mortality [1.24 (95% confidence interval: 1.17-1.33) for VAT and 1.24 (1.17-1.31) for FMR in men; and 1.11 (1.03-1.21) for VAT in women], except that the 1st quintile of FMR in women had the greatest HR [1.18 (1.09-1.27)]. Significant interactions were observed in both sexes according to age category (P for interaction < 0.05). Among men <50 years, participants in the 1st and 5th quintiles of VAT and FMR had significantly higher risks of mortality [1.30 (1.02-1.66) and 1.67 (1.27-2.19) in VAT; 1.25 (0.99-1.56) and 1.41 (1.11-1.79) in FMR, respectively]; in women, this phenomenon was observed in the >= 60 age group [1.16 (1.06-1.27) and 1.19 (1.08-1.31) in VAT; 1.18 (1.08-1.29) and 1.11 (1.01-1.22) in FMR, respectively]. VAT showed a linear positive association with mortality in women <60 years and a J-shaped association from respiratory disease in both sexes >= 60 years. FMR showed a linear positive association with mortality from cancer in men <60 years and a J-shaped association with mortality from cause-specific mortality in both sexes >= 60 years, except for mortality from cardiovascular disease in men. ConclusionsMost associations of VAT and FMR with all-cause mortality were J-shaped and were significantly modified by age status (<50, 50-59 and >= 60 years). The clinical implication is that regarding body composition and VAT mass, different health strategies may be adopted for people of different sexes and ages.
