Background & objectives Frailty is a geriatric syndrome with clinical and public health implications. It represents the state of increased vulnerability. This study aimed to estimate the prevalence of frailty and pre-frailty by demographic characteristics and geographical regions in India. ⋯ A sharp age-related increase in prevalence highlights the need for preventive measures. Furthermore, the high prevalence of frailty among women, illiterate and rural residents indicates the target population for receiving preventive interventions. Lastly, a heterogeneity in frailty prevalence across different States indicates the scope for region-specific programmes.

Background & objectives Given the importance of the role of hypoxia induced pathway in different cancers including head-and-neck squamous cell carcinoma (HNSCC), this study delved into elucidating the molecular mechanism of hypoxia-inducible factor-1α (HIF1α) activation in HNSCC. Additionally, it analyzes the alterations of its regulatory genes [von Hippel-Lindau (VHL) and LIM domain containing 1 (LIMD1)] and target gene vascular endothelial growth factor (VEGF) in head-and-neck lesions at different clinical stages in relation with human papillomavirus (HPV) infection. Methods Global mRNA expression profiles of HIF1α, VHL, LIMD1 and VEGF were evaluated from public datasets of HNSCC, followed by validation of their expression (mRNA/protein) in an independent set of HPV+ve/-ve HNSCC samples of different clinical stages. ⋯ The methylation pattern of VHL and LIMD1 promoters in the basal/parabasal layers of normal epithelium correlated with their expression, exhibiting a gradual increase with the progression of HNSCC. The H/M expression of HIF1α/VEGF proteins and reduced VHL expression was associated with poor clinical outcomes. Interpretation & conclusions The results of this study showed differential regulation of the LIMD1-VHL-HIF1α pathway in HPV positive and negative HNSCC samples, illustrating the molecular distinctiveness of these two groups.

Background & objectives Cardiovascular diseases (CVDs) are a leading cause of mortality worldwide. The aim of this investigation was to study the role of biological markers in predicting the risk of carotid and coronary artery atherosclerosis. Methods A total of 161 males in the age group of 30-65 yr were included in this study. ⋯ In the present investigation, we demonstrated the clear increase in the inflammatory markers (IL-8) in individuals with subclinical atherosclerosis. This fact can be explained by the oxygen stress activation. In individuals with coronary artery stenosis (50% and more), the increase in IL-10 levels demonstrates, to our opinion, the activation of antioxidant protection activation.

Background & objectives Cardiovascular diseases (CVDs) are extremely prevalent in India, making early detection of people at high risk for CVDs and prevention crucial. This study aimed to estimate CVD risk distribution in older adults (40-69 yr) in India using WHO's non-laboratory risk chart and identify factors associated with elevated CVD risk (10%). Methods The current study used a nationally representative sample of 40-69 yr adults in India. ⋯ The estimated 10-year CVD risk was higher for people with unemployed [Adjusted Odds Ratio (AOR): 5.12; 95% Confidence Interval (CI): 3.63, 7.24], followed by raised blood glucose (AOR: 1.81; 95%CI: 1.39, 2.34). Interpretation & conclusions The non-laboratory-based chart proves valuable in low-resource settings, especially at the primary healthcare level, facilitating efficient CVD risk assessment and resource allocation. Further research is needed to explore the association of second-hand smoke with CVD risk in the Indian population.

Background & objectives Medication-related harm is known to be the cause for about 1/10th of hospitalizations. Some estimates from India show that about 90 per cent of medicines consumed are inessential or irrational and contribute towards high out-of-pocket expenditure on health. In this context, the Indian Council of Medical Research in 2022 constituted a National Task Force (NTF) to explore possible solutions that could improve safe and rational use of medicines (SRUMs). ⋯ Patient engagement, which underlines many of the top scoring ideas found in this study, is also inclined with the top research priorities reported by the WHO priority exercise on research into the safe use of medicines. However, to the best of our knowledge, this is the first such work from a low- and middle- income country on medication safety and rational use of medicines. The findings of this research priority-setting exercise can help to guide research for the development of policy-relevant and novel interventions to improve SRUM in India.
