Work Related Low Back Pain in Sedentary Railway Officials of the Age Group 30 to 60 Years at Chhatrapati Shivaji Maharaj Terminus Mumbai- A Survey Study
A significant prevalence of work-related low back pain (LBP) was identified among sedentary railway officials aged 30 to 60 years at Chhatrapati Shivaji Maharaj Terminus, Mumbai. The study found that 61% of the 100 participants reported LBP, with a notable gender disparity—44 males and 17 females—highlighting higher incidence in male officials. Prolonged sitting and desk work were primary contributors to discomfort. The research employed a cross-sectional survey using the Modified Oswestry Low Back Pain Disability Questionnaire to assess disability levels associated with LBP. While the study provides insights into ergonomic challenges faced by railway officials, its limitations include a gender imbalance, focus on a single station, and lack of detailed work load or doctor consultation data.
Assessment of Biofilm Inhabitants of Deteriorated Surfaces of Heritage Sites
A comparative analysis of bacterial biofilm inhabitants on deteriorated surfaces of two UNESCO World Heritage Sites—Chhatrapati Shivaji Maharaj Terminus (CSMT) and Ajanta Caves (AJC)—reveals distinct microbial communities and functional profiles. While both sites host common environmental bacteria like Pseudomonas and Bacillus, AJC exhibits significantly higher bacterial diversity than CSMT, which is better maintained. Metagenomic sequencing identified abundant sulfate reducers (15.4% in CSMT vs. 29.8% in AJC) and nitrate reducers (36.3% in CSMT vs. 25.1% in AJC), suggesting their role in surface deterioration. Biofilm-associated genes (alg1 and pelA) were detected, indicating the presence of biofilm-forming bacteria on heritage surfaces. This integrated approach offers a framework for tracking biofilm bacteria to assess risks and guide conservation strategies.
