Assessment of knowledge, attitudes, and practices regarding air pollution among traffic polices in Dhaka city, Bangladesh: a cross-sectional study.
BMC Public Health
December 2024
Department of Public Health and Informatics, Jahangirnagar University, Savar, Dhaka, 1342, Bangladesh.
Background: The increasing number of motor vehicles in Dhaka city is contributing to a rise in air pollution. Prolonged exposure to vehicle emissions has led to various health issues for everyone, but traffic policies might be particularly affected. This study aims to evaluate their knowledge, attitudes, and practices regarding air pollution, with the goal of raising awareness and promoting healthier practices to mitigate the adverse effects of pollution.

To explore the internal factors related to the strong growth and competitive ability of weedy rice during the seedling period, we collected two biotypes of Japonica weedy rice from Northeast China, four biotypes of Indica weedy rice from Eastern China and Southern China, and two biotypes of cultivated rice, Zhendao-8 (ZD-8) and Shanyou-63 (SY-63), which were used as controls in a pot experiment. Under homogeneous garden planting conditions, we measured the vascular bundle size (VBS), vascular bundle number (VBN), leaf thickness (LT), air cavity size (ACS), stomatal size (SS), stomatal density (SD), net photosynthetic rate (Pn) and stomatal conductance (Gs) of the weedy and cultivated rice biotypes. A comprehensive analysis was performed to explore the correlation between the seedling leaf structure and the photosynthetic indices of the biotypes.

Black carbon or elemental carbon (EC) in the atmosphere plays an ambiguous role in acute respiratory toxic effects. Here, we evaluate the contribution of EC to the short-term toxicity (including cytotoxicity and oxidative stress potency) of fine particulate matter (PM) on the human respiratory tract using in vitro airway organoids and cell lines. The toxic potency of EC per unit mass, including char and soot, is more than 2 orders of magnitude lower than that of polycyclic aromatic hydrocarbons (PAHs), which are coemitted from incomplete combustion.

J Neurol Neurosurg Psychiatry

Department of Neurology, National Taiwan University Hospital, Taipei, Taiwan
Background: Recent evidence suggests brain-first Parkinson's disease (PD) may start from the olfactory system, indicating potential inhalational exposure to causal agents. We investigated the impact of long-term exposure to various air pollutants on PD incidence using both single- and multi-pollutant models to account for interactions between pollutants.
Methods: This retrospective population study used data from Taiwan's National Health Insurance Research Database (2006 and 2018) and included individuals aged 40-65 without PD.
Vascular air embolism in neonates: a literature review.
Am J Perinatol
December 2024
Mount Sinai Hospital Pediatrics, TORONTO, Canada.
Background Neonatal vascular air embolism is a rare but often fatal condition. The literature comprises mostly case reports and a few dated systematic reviews. Our objective was to review all case reports of neonatal vascular air embolism to date, and provide up-to-date information about patient characteristics, clinical presentations, outcomes, pathogenesis, diagnosis, prevention, treatment and prognosis.
