Health and Economic Benefits of Air Pollution Reductions in Vietnam During 2020-2021.

This paper explores the potential reduction in the number of deaths and the corresponding economic benefits in Vietnam that could have arisen from the decreased in concentrations of particulate matter with a diameter of 2.5 μm or less (PM) and nitrogen dioxide (NO). Using Global Exposure Mortality Models, we estimated the potential health and economic benefits on people aged 25 and above across Vietnam's 63 provinces.

Mortality benefits of reduction fine particulate matter in Vietnam, 2019.

Introduction And Objectives: Studies assessing the health benefits of air pollution reduction in Vietnam are scarce. This study quantified the annual mortality burden due to PM pollution in Vietnam above the World Health Organization recommendation for community health (AQG: 5 μg/m) and the proposed National Technical Regulation on Ambient Air Quality ( 15 μg/m).

Methodology: This study applied a health impact assessment methodology with the hazard risk function for non-communicable diseases (NCDs) and lower respiratory infections (LRIs) in the Global Exposure Mortality Model (GEMM) to calculate attributable deaths, Years of Life lost, and Loss of Life expectancy at birth due to air pollution in the Vietnamese population above 25 years of age in 11 provinces.

Mortality Burden due to Exposure to Outdoor Fine Particulate Matter in Hanoi, Vietnam: Health Impact Assessment.

This study reports the mortality burden due to PM exposure among adults (age >25) living in Hanoi in 2017. We applied a health impact assessment methodology with the global exposure mortality model and a PM map with 3 × 3 km resolution derived from multiple data sources. The annual average PM concentration for each grid ranged from 22.

Exposure to air pollution and risk of hospitalization for cardiovascular diseases amongst Vietnamese adults: Case-crossover study.

Background: Associations between hospital admissions and ambient air pollutants in the Vietnamese population have been reported in previous studies. However, most studies were conducted in Hanoi or Hochiminh city. We used hospital records of seven hospitals in Northern Vietnam to investigate short-term associations between ambient air pollutants and hospital admissions due to cardiovascular conditions.

Two polymorphisms, rs2046210 and rs3803662, are associated with breast cancer risk in a Vietnamese case-control cohort.

Breast cancer is the most common cancer in women worldwide. Breast tumorigenesis encompasses both extrinsic and intrinsic factors. Among intrinsic aspects, the appearance of DNA variation can cause genetic instability, which may lead to carcinogenesis.

Copper(i)-catalysed asymmetric allylic reductions with hydrosilanes.

A copper(i)-catalysed asymmetric allylic reduction enables a regio- and stereoselective transfer of a hydride nucleophile in an S2'-fashion onto allylic bromides. This transformation represents a conceptually orthogonal approach to allylic substitution reactions with carbon nucleophiles. A copper(i) complex based upon a chiral N-heterocyclic carbene (NHC) ligand allows for stereoselectivity reaching 99% ee.

Copper(I)-Catalyzed Allylic Substitutions with a Hydride Nucleophile.

An easily accessible copper(I)/N-heterocyclic carbene (NHC) complex enables a regioselective hydride transfer to allylic bromides, an allylic reduction. The resulting aryl- and alkyl-substituted branched α-olefins, which are valuable building blocks for synthesis, are obtained in good yields and regioselectivity. A commercially available silane, (TMSO)2Si(Me)H, is employed as hydride source.
