Introduction: In 2012, 8% of the 2.3 million work-related deaths globally were from chronic respiratory diseases (CRDs). This study was undertaken to estimate the prevalence of respiratory morbidity among the drivers and conductors of the public road transport network in Kochi.
Methodology: A cross-sectional study was carried out in the public bus stand (South), Kochi between September 2015 and 2017 among bus drivers and conductors. The interview was conducted among 300 bus drivers and conductors using a locally adapted version of ATS-DLD-78-A questionnaire. Lung function assessment was done using a Mini Wright peak flow meter and a portable spirometer. Data were tabulated using MS Excel and analyzed using SPSS v20.
Results: The prevalence of CRD among bus drivers and conductors was found to be 9.97% (95% CI 7.34-14.66) and chronic respiratory symptoms were found to be 19.2% (95% CI 14.58-23.82). On logistic regression, the independent predictors for the CRD were found to be working for more than 15 h/day (OR 2.815, 95% CI 1.26-6.28) and working for more than 4 days/week (OR 2.462, 95% CI 1.12-5.39).
Conclusion: CRD exists as a public health problem affecting approximately one in ten bus drivers and conductors in Kochi city. Applying the logical principles of ergonomics by modifying duty hours may be considered.

The pathophysiology of multiple sclerosis (MS) remains poorly understood despite decades of tremendous research efforts. Advances in neuroradiography coupled with availability of unbiased approaches including spatial transcriptomics, proteomics, metabolomics, and lipidomics that are compatible with brain and fluid specimens from patients raise hope that discovery of novel disease drivers is on the horizon. Once thought to be little more than salty bathwater, our modern understanding of cerebrospinal fluid (CSF) suggests the CSF as a compelling, critical regulator of brain function in health and disease.

Bus drivers and conductors are facing various health hazards due to stressful working conditions. They are exposed to various occupational hazards which lead to deterioration of their health over a period of time. Therefore, it is of interest to evaluate the prevalence of diabetes and hypertension among bus drivers and conductors and to determine the factors associated with diabetes and hypertension.

Na superionic conductor (NASICON) materials hold promise as solid-state electrolytes due to their wide electrochemical stability and chemical durability. However, their limited ionic conductivity hinders their integration into sodium-ion batteries. The conventional approach to electrolyte design struggles with comprehending the intricate interactions of factors impacting conductivity, encompassing synthesis parameters, structural characteristics, and electronic descriptors.

Background Health hazards faced by bus drivers and conductors due to their stressful working conditions can vary greatly depending on the country and specific circumstances. In some regions, stringent regulations mitigate the risks, while in others, lack of enforcement exacerbates the situation. The common mental health issues faced by bus drivers and conductors are anxiety and depression.

Molecularly rigid polymers with internal charges (positive charges induced by amine methylation) allow electroosmotic water flow to be tuned by adjusting the charge density (the degree of methylation). Here, a microporous polyamine (PIM-EA-TB) is methylated to give a molecularly rigid anion conductor. The electroosmotic drag coefficient (the number of water molecules transported per anion) is shown to increase with a lower degree of methylation.
