Objectives: This study aims to assess the oral health-related quality of life (OHRQoL) among the Irula tribes and to know the factors influencing quality of life among the elderly irula tribes of Tamil Nadu., Methods: This cross-sectional study was conducted in the Northern district of Tamil Nadu, including 486 Irula individuals aged 65 and above. Participants were selected using a multistage sampling method. Data were collected through a structured questionnaire, including the Geriatric Oral Health Assessment Index (GOHAI) to evaluate OHRQoL. The study tool covered demographics, medical history, and oral health issues. Data analysis was performed using SPSS version 23, with logistic regression applied to account for confounders., Results: The sample primarily consisted of individuals aged 65-69 years (55.6%), with a predominance of females (76.3%). The majority were Hindu (94.9%) and lived in nuclear families (88.3%). Educational levels were low, with 66.5% being illiterate. Most participants were agricultural laborers (64.6%) and had low monthly incomes. GOHAI results revealed that many respondents faced significant oral health challenges, including difficulties with eating, speaking, and discomfort. Multivariate analysis showed that educational level significantly affected OHRQoL, with higher education correlating with better quality of life. Arthritis was associated with poorer OHRQoL, while other health conditions did not show significant impacts., Conclusion: The study highlights severe oral health issues among the Irula community, with significant physical and psychological impacts. Educational attainment plays a crucial role in OHRQoL, while arthritis notably affects quality of life. The findings emphasize the need for targeted oral health interventions and increased awareness in tribal communities to improve overall health outcomes. Further research in larger populations is necessary to comprehensively understand and address geriatric oral health needs., (© 2024 The Author(s).

In the present study, resveratrol, a polyphenolic SIRT1 activator was evaluated for its SIRT1 activation in an in vitro fluorescent based assay (EC(50) : 7 μM). The efficacy of resveratrol was also evaluated in ob/ob mice for its antidiabetic and associated metabolic effects. Mice aged 5-8 weeks were included in four groups; control and resveratrol at 5, 15, 50 mg/kg, b.i.d. and were dosed orally. After 4 weeks of drug treatment, body weights were noted and random blood glucose and insulin was estimated for the antidiabetic effect. Animals were also subjected to the oral glucose tolerance test to observe any improvement in the glucose excursion. Triglycerides, total cholesterol, adiponectin and free fatty acid levels were also estimated. The results showed that resveratrol exhibited significant antihyperglycemic activity with an improvement in the insulin levels compared with the control mice. There was also a significant improvement observed in the glucose excursion in the oral glucose tolerance test performed for 120 min; although an insignificant improvement in the triglycerides, total cholesterol, adiponectin and free fatty acid levels was observed at different doses of resveratrol tested. The present findings suggest that resveratrol is an antihyperglycemic agent and drugs similar to resveratrol can be considered as an effective therapeutic adjuvant for the current treatment of diabetes mellitus., (Copyright © 2010 John Wiley & Sons, Ltd.)
