Nature-based solutions for securing contributions of water, food, and energy in an urban environment.

There is growing awareness that nature-based solutions (NBS) prevent negative effects and secure ecosystem services. However, the potential of NBS to provide intended benefits has not been rigorously assessed. Water, food, and energy (WFE) are essential for human well-being. This study highlights the importance of NBS in terms of water, food, and energy. A set of on-site NBS that includes permeable pavements, plant microbial fuel cells, bio-filtration basins, and rain gardens is used to determine the contribution of NBS to the environmental and economic development of urban environments. The results of this study show that NBSs benefit an urban environment in terms of water treatment, stormwater retention, food production and energy generation, carbon sequestration, pollination, sedimentation retention, and cultural services dimension. This research highlights an urgent need for the integration of water, food, and energy plans to ensure that NBSs contribute to the environment and for the conservation of ecosystem services.

Non-Vitamin K Antagonist Oral Anticoagulants in Secondary Stroke Prevention in Atrial Fibrillation Patients: An Updated Analysis by Adding Observational Studies.

BACKGROUND: This meta-analysis aimed to evaluate the efficacy and safety of non-vitamin K antagonist oral anticoagulants (NOACs) versus vitamin K antagonists (VKAs) in secondary stroke prevention in atrial fibrillation (AF) patients. METHODS: PubMed and Embase electronic databases were systematically searched from January 2009 to July 2019 for relevant randomized clinical trials and observational studies. A random-effects model was applied in the pooled analysis. RESULTS: A total of 14 studies (4 randomized clinical trials and 10 observational studies) were included. Based on the randomized clinical trials, compared with VKA use, the use of NOACs was associated with decreased risk of stroke and systemic embolism, major bleeding, and intracranial bleeding. Based on the observational studies, compared with VKAs, the subgroup analysis showed that dabigatran and rivaroxaban were associated with a reduced risk of stroke or systemic embolism, whereas dabigatran and apixaban were associated with a decreased risk of major bleeding. CONCLUSION: Based on current data, the use of NOACs is at least non-inferior to the use of VKAs in AF patients for secondary stroke prevention irrespective of NOAC type.

Implications of Necroptosis for Cardiovascular Diseases.

Necroptosis is a non-apoptotic programmed cell death pathway, which causes necrosis-like morphologic changes and triggers inflammation in the surrounding tissues. Accumulating evidence has demonstrated that necroptosis is involved in a number of pathological processes that lead to cardiovascular diseases. However, the exact molecular pathways linking them remain unknown. Herein, this review summarizes the necroptosis-related pathways involved in the development of various cardiovascular diseases, including atherosclerosis, cardiac ischemia-reperfusion injury, cardiac hypertrophy, dilated cardiomyopathy and myocardial infarction, and may shed light on the diagnosis and treatment of these diseases.

Plasma Homocysteine Levels Are Associated With Circadian Blood Pressure Variation in Chinese Hypertensive Adults.

BACKGROUND: Homocysteine-lowering intervention with folate was recently shown to be able to increase day-night difference of blood pressure (BP) in humans indicating a potential relationship between homocysteine and circadian BP variation. We thus sought to investigate the association between plasma total homocysteine level (tHcy) and circadian BP variation in hypertensive adults. METHODS: We enrolled 244 eligible dipping and 249 nondipping BP status adults from 560 adults who were randomly sampled from 5,233 Chinese hypertensive adults who received ambulatory BP monitoring (ABPM). We further enrolled 390 adults with CC/CT genotypes of the methylenetetrahydrofolate reductase (MTHFR) and 79 TT genotype who received ABPM at the same time from 1858 hypertensive adults with MTHFR polymorphisms detection. RESULTS: Plasma tHcy in nondippers was significantly higher than dippers (P < 0.001). Simple linear analysis revealed that tHcy significantly correlated with nocturnal systolic BP fall (r = -0.145, P = 0.001) and diastolic BP fall (r = -0.141, P = 0.002). Multivariate logistic regression analysis further identified tHcy as an independent factor correlated with the presence of nondipping BP status in hypertensive adults (odds ratio: 1.873, 95% confidence interval: 1.171-2.996, P = 0.009). The percentage of dipping BP status was 19.49% or 8.86% and the percentage of nondipping BP status was 80.51% or 91.14% in CC/CT or TT genotypes, respectively. The above different between CC/CT and TT genotypes was significant (P = 0.024). CONCLUSIONS: These results indicated that high homocysteine levels associate with disturbed circadian BP variation in Chinese hypertensive adults.
