RESUMO
OBJECTIVE: To investigate the associations of tea, coffee, and red wine intakes with health risks among individuals with hypertension. METHODS: This prospective cohort study included participants with hypertension from the UK Biobank cohort. Study exposures included self-reported intakes of coffee, tea, and red wine. The primary outcome was all-cause mortality, and the secondary outcomes were cardiovascular mortality and cardiovascular disease. The associations of beverage intake with outcomes were analyzed using Cox regression models. The hazard ratios and 95% confidence intervals were estimated. RESULTS: A total of 187 708 participants with hypertension were included. The median follow-up period was 13.8 years. In individuals with hypertension, drinking one to two cups/day of coffee or three to four cups/day of tea was significantly associated with the lowest risk of all-cause mortality compared with less than one cup/day [hazard ratio for coffee, 0.943 (95% confidence interval, 0.908-0.979); hazard ratio for tea, 0.882 (95% confidence interval, 0.841-0.924)]. Red wine intake was inversely associated with all-cause mortality risk. Dose-response analysis revealed that high coffee intake (approximately greater than or equal to six cups/day) was significantly associated with increased risks of cardiovascular mortality and cardiovascular disease, but high tea and red wine intakes were not. Furthermore, replacing plain water with tea, but not coffee, significantly reduced the risks of all-cause mortality and cardiovascular disease. Replacing other alcoholic beverages with red wine also significantly reduced the risks of all three outcomes. CONCLUSIONS: These findings suggest that tea and red wine, but not coffee, can be part of a healthy diet for the hypertensive population.

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) were developed as antidiabetic agents, but accumulating evidence has shown their beneficial effects on the cardiovascular system. Analyses of the EMPA-REG OUTCOME trial (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) suggested that these benefits are independent of glycemic control. Several large-scale outcome trials of SGLT2i also showed cardiovascular benefits in nondiabetic patients, strengthening this perspective. Extensive animal and clinical studies have likewise shown that mechanisms other than the antihyperglycemic effect underlie the cardiovascular benefits. Recent clinical guidelines recommend the use of SGLT2i in patients with type 2 diabetes mellitus and cardiovascular diseases because of the proven cardiovascular protective effects. Since the cardiovascular benefits are independent of glycemic control, the therapeutic spectrum of SGLT2i will likely be extended to nondiabetic patients.

Highly sensitive infrared photodetectors are needed in numerous sensing and imaging applications. In this paper, we report on extended short-wave infrared (e-SWIR) avalanche photodiodes (APDs) capable of operating at room temperature (RT). To extend the detection wavelength, the e-SWIR APD utilizes a higher indium (In) composition, specifically In0.3Ga0.7As0.25Sb0.75/GaSb heterostructures. The detection cut-off wavelength is successfully extended to 2.6 µm at RT, as verified by the Fourier Transform Infrared Spectrometer (FTIR) detection spectrum measurement at RT. The In0.3Ga0.7As0.25Sb0.75/GaSb heterostructures are lattice-matched to GaSb substrates, ensuring high material quality. The noise current at RT is analyzed and found to be the shot noise-limited at RT. The e-SWIR APD achieves a high multiplication gain of M~190 at a low bias of Vbias=- 2.5 V under illumination of a distributed feedback laser (DFB) with an emission wavelength of 2.3 µm. A high photoresponsivity of R>140 A/W is also achieved at the low bias of Vbias=-2.5 V. This type of highly sensitive e-SWIR APD, with a high internal gain capable of RT operation, provides enabling technology for e-SWIR sensing and imaging while significantly reducing size, weight, and power consumption (SWaP).
RESUMO
BACKGROUND: There is insufficient evidence to show that the guidelines' recommendations of physical activity (PA) are associated with long-term benefits in individuals with hypertension. METHODS: This prospective cohort study included UK Biobank participants with hypertension. Time spent on vigorous-intensity PA (VPA), moderate-intensity PA (MPA), and light-intensity PA (LPA) measured by wrist-worn accelerometer were extracted. The primary outcomes were major adverse cardiovascular events (including cardiovascular death, stroke, and myocardial infarction) and all-cause mortality. The secondary outcomes were cardiovascular death, myocardial infarction, and stroke, respectively. The relationships of PA with outcomes were analyzed using Cox regression models. RESULTS: This study included 49 060 eligible participants with a median follow-up of 7.0 years. MPA was inversely associated with risks of major adverse cardiovascular events and all-cause mortality. Modest amounts of LPA or VPA were likely to be more beneficial than higher amounts of either in all-cause death or cardiovascular outcomes. Compared with the least active group, 150 to 300 min/wk of MPA or more was significantly associated with decreased risk of all-cause death (by 34%-54%) and major adverse cardiovascular events (by 23%-41%), but 75 to 150 min/wk of VPA or more was associated with few further benefits, even weakening the cardiovascular benefits. CONCLUSIONS: MPA had an inverse dose-response association with the risk of all-cause mortality and cardiovascular outcomes in individuals with hypertension. Modest amounts of LPA or VPA are also beneficial, but higher amounts may be not. MPA may be the optimal PA intensity for individuals with hypertension. Further researches are required to determine whether high levels of VPA should be recommended.

Importance: In recent years, significant progress has been made in the pharmacologic treatment of heart failure (HF) with reduced ejection fraction (HFrEF), but there is still insufficient evidence for drug therapy for HF with preserved ejection fraction (HFpEF) and mildly reduced ejection fraction (HFmrEF). Objective: To compare the outcomes associated with different drug combinations for the treatment of HFpEF and HFmrEF. Data Sources: A search of the PubMed, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases was conducted for studies published from inception to October 9, 2021. Study Selection: Randomized clinical trials on the use of angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), angiotensin receptor-neprilysin inhibitors (ARNIs), mineralocorticoid receptor antagonists (MRAs), ß-blockers, and sodium-glucose cotransporter 2 (SGLT2) inhibitors for patients with HFpEF or HFmrEF. Data Extraction and Synthesis: Data extraction and bias assessment were independently performed by 2 reviewers following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. All data for 3 outcomes were pooled with a fixed-effect model. Main Outcomes and Measures: The main outcomes were first hospitalization for HF, all-cause mortality, and cardiovascular mortality. Hazard ratios (HRs) and 95% credible intervals (CrIs) were evaluated using a bayesian network meta-analysis model. Results: In this analysis, 19 randomized clinical trials, including 20â¯633 patients with HF and an ejection fraction of 40% or more, without a remarkable risk of bias were included. Compared with placebo, no treatments were associated with a significant reduction in the risk of all-cause death or cardiovascular death. SGLT2 inhibitors, ARNIs, and MRAs were associated with a significant decrease in the risk of HF hospitalization compared with placebo (SGLT2 inhibitors: HR, 0.71 [95% CrI, 0.60-0.83]; ARNIs: HR, 0.76 [95% CrI, 0.61-0.95]; MRAs: HR, 0.83 [95% CrI, 0.69-0.99]), and SGLT2 inhibitors were the optimal drug class in terms of reducing the risk for HF admission. Sensitivity analysis results demonstrated a progressive decrease in the risk of HF admission and an advance in mean rank associated with the increasing use of drug classes. Conclusions and Relevance: The findings of this study suggest that SGLT2 inhibitors were the optimal drug class for HFpEF and HFmrEF, consistent with the most recent guideline recommendation. The incremental use of combinations of SGLT2 inhibitors, ACE inhibitors or ARBs, and ß-blockers may be associated with accumulative benefits in HF hospitalization rather than all-cause death among patients with HFpEF and HFmrEF.

Background: The medical treatments of chronic heart failure have made remarkable progress in recent years. It is crucial to determine the optimal drug combination based on current evidence. Methods: A search of PubMed, EMBASE, and Cochrane CENTRAL databases was conducted for studies on angiotensin receptor-neprilysin inhibitors (ARNIs), sodium-glucose cotransporter 2 inhibitors (SGLT2is), angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), beta-blockers (BBs), mineralocorticoid receptor antagonists (MRAs), and ivabradine (IVA) between 1987 and 2021. The network meta-analysis was performed to compare the efficacy of drug therapies in heart failure with reduced ejection fraction (HFrEF). Results: Forty-eight randomized controlled trials (RCTs), which overall included 68,074 patients with HF and left ventricular ejection fraction (LVEF) ≤ 40%, were identified and included in the network meta-analysis. The efficacies of 13 intervention classes, including monotherapies or combinations of ACEI, ARB, ARNI, BB, MRA, SGLT2i, IVA, and placebo, on hospitalization for HF, cardiovascular mortality, and all-cause mortality were compared. Among the 13 included interventions, ARNI+BB+MRA, SGLT2i+ACEI+BB+MRA, and IVA+ACEI+BB+MRA were found to be best in terms of all three outcomes. Compared with placebo, these three drug combinations were associated with significant reductions in the risk of all-cause death, cardiovascular mortality and hospitalization for HF. Conclusions: ARNI+BB+MRA, SGLT2i+ACEI+BB+MRA, and IVA+ACEI+BB+MRA were the top three therapies for patients with HFrEF. The increasing use of combinations of conventional and novel drugs contributed to progressive reductions in hospitalization and mortality in patients with HFrEF.
