Background: Both smoked and smokeless tobaccos play crucial roles in forming potentially malignant oral disorders. Studies are scant in India, particularly among vulnerable tribal populations. Odisha, with the highest number of tribes in India, stands at the top in smokeless tobacco use among major states. The present study explores tobacco use status among Indian tribes by evaluating the OPMD risks.. Methods: A cross-sectional study was carried out among the tribal populations in Odisha. Data was collected pertaining to sociodemographic profile, tobacco use and prevalence of oral potentially malignant disorders (OPMD). The Fagerstrom Test for Nicotine Dependence (FTND) scale was used to evaluate tobacco dependency.. Results: The findings revealed that 75.2% of people are tobacco consumers. Half of the studied population consumes Dukuta and Khaini. Maximum people, including 54.2% of youth, fall in the high nicotine dependence category. Additionally, 45.2% of the participants reported mouth lesions, and 27.1% with potentially malignant disorders (PMD). The incidence of tobacco pouches in the studied population is 22.9%, followed by 12.4% leukoplakia lesions. Conclusion: A health policy for community-level intervention toward tobacco cessation and early diagnosis of previously undiagnosed OML (oral malignant lesion) and OPMD would be a positive strategy.

India has targeted elimination of lymphatic filariasis (LF) through mass drug administration (MDA) by 2027. Mapping of LF endemic areas is a priority for implementation of MDA. Current national LF remapping tool for unsurveyed/uncertain districts, have many limitations. The WHO has recommended a sensitive and rapid remapping protocol (Mini-TAS), that needs validation in Indian setting. Hence, in the present study a comparative assessment of these two protocols (national protocol vs Mini-TAS) was undertaken in two non-MDA districts of Odisha, with unknown filarial endemicity but reporting chronic cases. Purposive sampling was done in five top sites based on filarial case count as per the national protocol. Random 30 cluster survey was done by conducting school based Mini-TAS, Microfilariae (Mf) survey among adults (>10 years) in villages/wards with schools and Molecular Xenomonitoring (MX) of infection in vectors. Costing by activity and items of the surveys was acomplished using itemized cost menu. In Kalahandi, one of the five purposive sampling sites showed Mf prevalence above threshold (> 1%). But except Mini-TAS neither MX nor house-hold Mf survey among adults could detect the infection above the threshold. While in Balangir, Mf prevalence in all purposive sampling sites,Mini-TAS, Mf prevalence among adult and MX were above the respective thresholds confirming endemicity of LF in the district. The per sample cost of purposive sampling for Mf was the lowest INR 41, followed by adult Mf sampling INR 93. Mini-TAS and MX were expensive with INR 659 and 812 respectively. The study demonstrates that though all the sampling methods could detect filarial infection above the threshold in high-risk areas, Mini-TAS could only detect infection in low-risk areas. Therefore, in the national programme Mini-TAS can be used as a decision-making tool to determine whether to exclude/ include a district having uncertain endemicity for MDA. [ABSTRACT FROM AUTHOR]

India, a persistently significant contributor to the global malaria burden, rolled out several anti-malaria interventions at the national and state level to control and recently, to eliminate the disease. Odisha, the eastern Indian state with the highest malaria burden experienced substantial gains shown by various anti-malaria initiatives implemented under the National Vector-borne Disease Control Programme (NVBDCP). However, recalcitrant high-transmission "pockets" of malaria persist in hard-to-reach stretches of the state, characterised by limited access to routine malaria surveillance and the forested hilly topography favouring unbridled vector breeding. The prevalence of asymptomatic malaria in such pockets serves as perpetual malaria reservoir, thus hindering its elimination. Therefore, a project with the acronym DAMaN was initiated since 2017 by state NVBDCP, targeting locally identified high endemic 'pockets' in 23 districts. DAMaN comprised biennial mass screening and treatment, provisioning of long-lasting insecticidal net (LLIN) and behavioural change communication. Subsequently, to inform policy, assessment of DAMaN was conceived that aims to estimate the coverage of the various components of the project; the prevalence of malaria, even at sub-patent level especially among pregnant/lactating women and children; and its impact on malaria incidence. A survey of DAMaN beneficiaries will measure coverage; and knowledge and practices related to LLIN; along with collection of blood specimens from a probability sample. A multi-stage stratified clustered sample of 2228 households (~33% having pregnant/lactating women) will be selected from 6 DAMaN districts. Routine DAMaN project data (2017–2018) and NVBDCP data (2013–2018) will be extracted. Rapid Diagnostic Test, Polymerase Chain Reaction and blood smear microscopy will be conducted to detect malarial parasitemia. In addition to measuring DAMaN's coverage and malarial prevalence in DAMaN pockets, its impact will be estimated using pre-post differences and Interrupted Time Series analysis using 2017 as the "inflection" point. The assessment may help to validate the unique strategies employed by DAMaN. [ABSTRACT FROM AUTHOR]

Some form of gambling can be observed in nearly every society, as the gratification felt upon winning in uncertain conditions is universal. A culturally distinct form of gambling, associated with a traditional sporting event of archery known as "teer," is innate to the province of Meghalaya, India. The objective of this study was to find genetic variants underlying this unique form of behavioral addiction. To better understand game-based gambling, we studied genetic variants related to dopaminergic pathways and other genes previously linked to various psychological disorders. This study was carried out on a sample of 196 Indo-Aryan adults from Shillong, Meghalaya. Genotyping of glial cell line-derived neurotrophic factor (GDNF) polymorphisms was carried out using real-time PCR. We further investigated 32 single nucleotide polymorphisms located in the 3′ UTR of additional genes of interest using an OpenArray® real-time PCR platform. Case–control analysis revealed a significant association between GDNF variant rs2973033 (p =.00864, χ2 = 13.132, df = 2) and contactin-associated protein-like 2 (CNTNAP2) variant rs2530311 (p =.0448, χ2 = 13.132, df = 2) with gambling. Association of the GDNF gene with gambling could be attributed to its involvement in the development and survival of dopaminergic neurons. Our result is in good agreement with previous data indicating the role of GDNF in certain substance addictions. Several rare variants in the CNTNAP2 gene were also implicated in alcohol addiction in a previous study. This pilot study provides further support for the role of GDNF and CNTNAP2 in addiction behaviors. [ABSTRACT FROM AUTHOR]

Background & objectives: Assessing healthcare seeking behaviour (HSB), healthcare utilization and related out-of-pocket expenditures of Particularly Vulnerable Tribal Groups (PVTGs) of India through a prism of the health system may help to achieve equitable health outcomes. Therefore, this comprehensive study was envisaged to examine these issues among PVTGs of Odisha, India. However, there exists no validated questionnaire to measure these variables among PVTGs. Therefore, a study questionnaire was developed for this purpose and validated. Methods: Questionnaire was constructed in four phases: questionnaire development, validity assessment, pilot testing and reliability assessment. Nine domain experts face validated questionnaire in two rounds, followed by a single round of quantitative content validity. Next, the questionnaire was pretested in three rounds using cognitive interviews and pilot-tested among 335 and 100 eligible individuals for the two sections healthcare seeking behaviour (HSB-Q) and maternal and child healthcare service utilization (MCHSU-Q). Internal consistency reliability was assessed for de novo HSB-Q. Results: On two rounds of expert-driven face validity, 55 items were eliminated from 200 items. Questionnaire showed moderate to high content validity (item-level content validity index range: 0.78 to 1, scale-level content validity index/universal agreement: 0.73; scale-level content validity index/average: 0.96 and multirater kappa statistics range: 0.6 to 1). During the pre-test, items were altered until saturation was achieved. Pilot testing helped to refine interview modalities. The Cronbach alpha and McDonald’s omega assessing internal consistency of HSB-Q were 0.8 and 0.85, respectively. Interpretation & conclusions: The questionnaire was found to be valid and reliable to explore healthcare seeking behaviour, maternal and child healthcare utilization and related out-of-pocket expenditure incurred by PVTGs of Odisha, India.
