Influence of ultra-processed food in the diet of South Indian young adults: an explanatory mixed method study.

PURPOSE: To determine the contribution of ultra-processed foods (UPFs) to overall macronutrient intake and their association with anthropometric measurements, and to explore the perceptions regarding UPF consumption among young adults in Puducherry, India. METHODS: This study included 630 participants from three colleges selected using multistage cluster sampling. Following the demonstration of portion estimation, dietary data from previous day were collected using a Google Form-based tool. The participant's anthropometric measures were taken. Food items were classified into NOVA groups and intake analysis was performed using DietSoft software. The participants with low and high consumption were identified and focus group discussions were conducted in each group using criterion sampling. RESULTS: Of all the participants, 178 (28.3%) were overweight or obese. UPF contributed 9.3% of total energy intake and 2.8% protein, 9.9% fat, and 9.9% carbohydrates. The most consumed UPFs were biscuits, wafers (25%), and potato chips(16.2%). No significant association was found between anthropometric measures and UPF consumption. Qualitative findings revealed four major themes, further explained using the socio-ecological framework. CONCLUSION: UPF consumption in the region was lower than that reported in other global and Indian studies. While our study did not find a significant association between UPF consumption and anthropometric measures, there is a concerning shift from traditional diets to increased UPF reliance, driven by convenience and commercial factors. Addressing this is crucial for healthier choices and combating non-communicable diseases during this pivotal life stage.

Prevalence and the factors associated with microalbuminuria among patients with type 2 diabetes mellitus and/or hypertension in the urban areas of Puducherry district: a cross-sectional study.

BACKGROUND: Microalbuminuria is an early indicator for renal and cardiovascular diseases, especially among patients with diabetes mellitus (DM) and hypertension (HTN). We determined the prevalence and the factors associated with microalbuminuria among patients with type 2 DM and/or HTN in the urban areas of the Puducherry district in India. METHODS: We included 225 patients aged 40-69 years with DM and/or HTN from a non-communicable diseases (NCDs) survey conducted during 2019-2020 in the urban areas of Puducherry district. The prevalence of microalbuminuria and various biological risk factors of NCDs were assessed as per the WHO STEPS methodology. The prevalence of microalbuminuria was presented as proportions (95% CI), and the adjusted prevalence ratio (aPR) was estimated using weighted forward stepwise generalized linear modelling. P-value ≤0.05 was considered statistically significant. RESULTS: The mean (SD) age of the patients was 54 (11) years. Over one-third (38.2%) (95% CI: 31.6-44.4) of patients with DM and/or HTN had microalbuminuria. The prevalence was highest among those having both DM and HTN 48% (95% CI: 37-59), followed by those having only DM 40.6% (95% CI: 29-52.2) and only HTN 27.7% (95% CI: 18.1-38.6). The prevalence of microalbuminuria was twice (aPR = 2.1, 95% CI: 1.1-3.9) higher among women and 2.4 times (95% CI: 1.12-5.1) higher among those having both DM and HTN as compared to those with only HTN. CONCLUSION: The prevalence of microalbuminuria among patients with DM and/or HTN is concerningly high. Population-based screening for microalbuminuria, especially among women and those having both DM and HTN, needs to be undertaken in the urban areas of Puducherry district.

Microalbuminuria serves as an early indicator for kidney and cardiovascular diseases, especially among patients with diabetes mellitus (DM) and hypertension (HTN). Our study focussed on determining the prevalence of microalbuminuria among individuals with type 2 DM and/or HTN in the urban areas of the Puducherry district in India. We included 225 patients aged 40­69 years with DM and/or HTN who participated in a non-communicable diseases (NCDs) survey conducted during 2019­2020 in urban Puducherry. We found that over one-third (38.2%) of patients with DM and/or HTN had microalbuminuria. The prevalence was highest among those having both DM and HTN (48%), followed by those having only DM (40.6%) and only HTN (27.7%). The prevalence of microalbuminuria was 2.1 times higher among women than men and 2.4 times higher among individuals with both DM and HTN compared to those with only HTN. These findings highlight the concerningly high prevalence of microalbuminuria among patients with DM and/or HTN in the urban areas of Puducherry district. To address this issue, it is crucial that the public health authorities of Puducherry district implement population-based screening initiatives for microalbuminuria, particularly targeting women and individuals with both DM and HTN in the urban areas of the Puducherry district.

High prevalence of abdominal obesities and metabolically unhealthy individuals in a highly urbanized district of India: findings of a cross-sectional survey in Puducherry.

BACKGROUND: Abdominal obesities are better markers for predicting cardiovascular abnormalities than risk stratification based only on body mass index (BMI). We aimed to estimate the prevalence of abdominal adiposities using predictive equations for Asian Indian adults and to determine the prevalence of metabolically healthy subjects among those overweight/obese and with normal BMI. METHODS: A community-based survey was conducted among those aged 18-69 years in the district of Puducherry between February 2019 and February 2020. We surveyed 2,560 individuals selected through multi-stage cluster random sampling from urban and rural areas (50 wards and 50 villages, respectively) of the district. Anthropometric measurements, such as height, weight, waist circumference, and blood pressure were recorded from each participant. Fasting blood sample was collected from each alternate participant to estimate metabolic risk factors. RESULTS: Over four-fifths (85.6%; 95% CI: 84.2-86.9) and two-thirds (69.7%; 95% CI: 67.9-71.6) of the population in the district had high levels of intra-abdominal adipose tissue (IAAT) and total abdominal fat (TAF), respectively. Both the risk factors were significantly higher among women and urban population. About 43% (95% CI: 41-44.9) of the population had high abdominal subcutaneous adipose tissue (SCAT) with a significantly higher prevalence among the urban population. Among those overweight/obese (n = 773), almost all 99.4% (95% CI: 98.7-99.9) were metabolically unhealthy. Among subjects with normal BMI (n = 314), only about 2.9% (95% CI: 1.3-4.8) were metabolically healthy. CONCLUSION: We highlight the substantially high prevalence of IAAT, TAF, and SCAT in the district of Puducherry. Almost all the study population was metabolically unhealthy irrespective of their BMI levels.

The distribution of abdominal fat is a better predictor of cardiovascular abnormalities in an individual than the risk assessment based only on body mass index (BMI). We conducted a community-based cross-sectional survey to estimate the prevalence of abdominal adiposities using predictive equations for Asian Indian adults and determine the prevalence of metabolically healthy subjects among those overweight/obese and with normal BMI. We surveyed 2,560 adults aged 18­69 years in the district of Puducherry between February 2019 and February 2020. We recorded each participant's anthropometric measurements, such as height, weight, waist circumference, and blood pressure and collected a fasting blood sample to assess their metabolic health status. Over four-fifths (85.6%) and two-thirds (69.7%) of the population in the district had high levels of intra-abdominal adipose tissue (IAAT) and total abdominal fat (TAF), respectively. Nearly half (43%) of the population had high abdominal subcutaneous adipose tissue (SCAT). Both the risk factors were substantially higher among women and the urban population. Among those overweight/obese, almost all (99.4%) were metabolically unhealthy; among those with normal BMI, only about 2.9% were metabolically healthy. From this study, we highlight the immediate need for population-based health promotion interventions, especially among women and urban residents of Puducherry district.

Development of prognostic scoring system for predicting 1-year mortality among pulmonary tuberculosis patients in South India.

BACKGROUND: Development of a prediction model using baseline characteristics of tuberculosis (TB) patients at the time of diagnosis will aid us in early identification of the high-risk groups and devise pertinent strategies accordingly. Hence, we did this study to develop a prognostic-scoring model for predicting the death among newly diagnosed drug sensitive pulmonary TB patients in South India. METHODS: We undertook a longitudinal analysis of cohort data under the Regional Prospective Observational Research for Tuberculosis India consortium. Multivariable cox regression using the stepwise backward elimination procedure was used to select variables for the model building and the nomogram-scoring system was developed with the final selected model. RESULTS: In total, 54 (4.6%) out of the 1181 patients had died during the 1-year follow-up period. The TB mortality rate was 0.20 per 1000 person-days. Eight variables (age, gender, functional limitation, anemia, leukopenia, thrombocytopenia, diabetes, neutrophil-lymphocyte ratio) were selected and a nomogram was built using these variables. The discriminatory power was 0.81 (95% confidence interval: 0.75-0.86) and this model was well-calibrated. Decision curve analysis showed that the model is beneficial at a threshold probability ~15-65%. CONCLUSIONS: This scoring system could help the clinicians and policy makers to devise targeted interventions and in turn reduce the TB mortality in India.

Correlation between Quality of Life and Burden in Caregivers of Advanced Stage Cancer Patients on Best Supportive Care.

Objectives: Patients with advanced cancer with incurable diseases are generally cared for by their families in India. There is a lack of data on the perceived caregiver burden, quality of life (QOL) of patients and caregivers in India, especially among cancer patients not on any oncologic management. Material and Methods: We conducted a cross-sectional study among 220 patients of advanced cancer on best supportive care and their respective 220 family caregivers. Our primary objective was to identify a correlation between caregiver burden and QOL. After taking informed consent from both patients and caregivers, we assessed the QOL of the patient using the European Organization for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 15 Palliative Care (QLQ C15PAL) questionnaire from the patient, assessing the Caregiver Burden using Zarit Burden Interview, assessing the QOL of the caregiver using the WHO QOL BREF Questionnaire, in a single session during their routine follow-up in the Palliative Care Clinic of our institution. Results: We noticed a statistically significant negative (Spearman) correlation between the Caregiver Burden as assessed by Zarit Burden Interview (ZBI) and the psychological (r = -0.302, P < 0.01), social (r= -0.498, P < 0.01) and environmental (r = -0.396, P < 0.01) domains of the WHO QOL BREF Questionnaire. Caregiving Burden as assessed ZBI total score was noted to have a statistically significant negative correlation with physical functioning (r = -0.37, P < 0.01), emotional functioning (r = -0.435, P < 0.01) and global QOL scores (r = -0.499, P < 0.01) assessed from the patient using the EORTC QLQ C15 PAL questionnaire. It also had a statistically significant small positive correlation with EORTC QLQ C15 PAL symptom scores, such as dyspnoea, insomnia, constipation, nausea, fatigue and pain. The median caregiver burden score was 39, showing higher burden as compared to previous studies. Caregivers who were spouses of the patient, illiterate, homemakers, with low-income families reported higher burden. Conclusion: A high perceived caregiving burden is associated with impaired QOL in family caregivers of advanced cancer patients on best supportive care. Multiple patient related factors and demographic factors tend to affect burden of the caregiver.

Nutritional Supplementation Would Be Cost-Effective for Reducing Tuberculosis Incidence and Mortality in India: The Ration Optimization to Impede Tuberculosis (ROTI-TB) Model.

BACKGROUND: Undernutrition is the leading cause of tuberculosis (TB) in India and is associated with increased TB mortality. Undernutrition also decreases quality of life and economic productivity. METHODS: We assessed the cost-effectiveness of providing augmented rations to undernourished Indians through the government's Targeted Public Distribution System (TPDS). We used Markov state transition models to simulate disease progression and mortality among undernourished individuals in 3 groups: general population, household contacts (HHCs) of people living with TB, and persons living with human immunodeficiency virus (HIV). The models calculate costs and outcomes (TB cases, TB deaths, and disability-adjusted life years [DALYs]) associated with a 2600 kcal/day diet for adults with body mass index (BMI) of 16-18.4 kg/m2 until they attain a BMI of 20 kg/m2 compared to a status quo scenario wherein TPDS rations are unchanged. We employed deterministic and probabilistic sensitivity analyses to test result robustness. RESULTS: Over 5 years, augmented rations could avert 81% of TB cases and 88% of TB deaths among currently undernourished Indians. Correspondingly, this intervention could forestall 78% and 48% of TB cases and prevent 88% and 70% of deaths among undernourished HHCs and persons with HIV, respectively. Augmented rations resulted in 10-fold higher resolution of undernutrition and were highly cost-effective with (incremental cost-effectiveness ratio [ICER] of $470/DALY averted). ICER was lower for HHCs ($360/DALY averted) and the HIV population ($250/DALY averted). CONCLUSIONS: A robust nutritional intervention would be highly cost-effective in reducing TB incidence and mortality while reducing chronic undernutrition in India.

Performance of WHO updated cardiovascular disease risk prediction charts in a low-resource setting - Findings from a community-based survey in Puducherry, India.

BACKGROUND AND AIM: The World Health Organization has revised the cardiovascular disease (CVD) risk prediction charts in 2019 for each of the 21 Global Burden of Disease regions. These charts (non-lab and lab versions) estimate the total CVD risk in an individual, of which the non-lab is for low-resource settings. We aimed to estimate the burden of ten-year risk of fatal or non-fatal CVD event in the district of Puducherry in India using 'non-lab' and 'lab' versions of WHO CVD risk prediction charts, and to evaluate the agreement between them. METHODS AND RESULTS: We included 710 individuals aged 40-69 years who participated in a district wide non-communicable diseases survey conducted in Puducherry, India, during 2019-20. Both charts use information on age, gender, systolic blood pressure and smoking status. Additionally, lab-chart requires individual's status on diabetes mellitus and total cholesterol while non-lab requires body mass index. Population in different CVD risk levels was presented using proportions (95% confidence intervals). Agreement between lab and non-lab charts was evaluated using Cohen's Kappa (k). The lab and non-lab charts estimated 3% (95% CI: 1.7-4.2) and none of the population respectively, to have high risk (≥20%) for fatal or non-fatal CVD event over the next ten years. Both the charts showed 89.4% (95% CI:87.2%-91.7%) concordance in CVD risk prediction indicating a good level of agreement (k = 0.653). CONCLUSION: WHO updated CVD risk prediction charts are feasible to apply when data is available and there is good agreement between non-lab and lab based charts.

Outcomes of teleconsultation services and patient satisfaction among pregnant women delivering at a tertiary care center in South India during coronavirus disease 2019 pandemic.

Coronavirus disease 2019 pandemic has disrupted the antenatal care in low- and middle-income countries such as India. Telemedicine was introduced for the first time in India for continuing antenatal care. Hence, a questionnaire-based descriptive cross-sectional study is done to assess the outcomes of teleconsultation services, factors influencing it, and patient's perceived satisfaction. Three hundred and fifty-five women who delivered the following teleconsultation from July 2020 to October 2020 were included in the study. Thirty-two percent were high-risk pregnancies and 15% of the babies required neonatal intensive care unit admission. Ninety-eight percent could convey their health concerns, 18% had a referral to other departments, and 25% had visited casualty. Sixty-three percent procured medicine through e-prescription. Seventy-six percent were happy with teleconsultation overcrowded clinic, 82% were happy about saving travel expenditure, whereas overall satisfaction was 50%. Fourteen percent did not have access to smartphone and 9% did not receive the call at scheduled time. Telemedicine has a vital role in managing pregnancy concerns during this pandemic.

Tuberculosis-Learning the Impact of Nutrition (TB LION): protocol for an interventional study to decrease TB risk in household contacts.

BACKGROUND: Comorbidities such as undernutrition and parasitic infections are widespread in India and other tuberculosis (TB)-endemic countries. This study examines how these conditions as well as food supplementation and parasite treatment might alter immune responses to Mycobacterium tuberculosis (Mtb) infection and risk of progression to TB disease. METHODS: This is a 5-year prospective clinical trial at Jawaharlal Institute of Post Graduate Medical Education and Research in Puducherry, Tamil Nadu, India. We aim to enroll 760 household contacts (HHC) of adults with active TB in order to identify 120 who are followed prospectively for 2 years: Thirty QuantiFERON-TB Gold Plus (QFT-Plus) positive HHCs ≥ 18 years of age in four proposed groups: (1) undernourished (body mass index [BMI] < 18.5 kg/m2); (2) participants with a BMI ≥ 18.5 kg/m2 who have a parasitic infection (3) undernourished participants with a parasitic infection and (4) controls-participants with BMI ≥ 18.5 kg/m2 and without parasitic infection. We assess immune response at baseline and after food supplementation (for participants with BMI < 18.5 kg/m2) and parasite treatment (for participants with parasites). Detailed nutritional assessments, anthropometry, and parasite testing through polymerase chain reaction (PCR) and microscopy are performed. In addition, at serial time points, these samples will be further analyzed using flow cytometry and whole blood transcriptomics to elucidate the immune mechanisms involved in disease progression. CONCLUSIONS: This study will help determine whether undernutrition and parasite infection are associated with gene signatures that predict risk of TB and whether providing nutritional supplementation and/or treating parasitic infections improves immune response towards this infection. This study transcends individual level care and presents the opportunity to benefit the population at large by analyzing factors that affect disease progression potentially reducing the overall burden of people who progress to TB disease. Trial registration ClinicalTrials.gov; NCT03598842; Registered on July 26, 2018; https://clinicaltrials.gov/ct2/show/NCT03598842.

Comparing tuberculosis gene signatures in malnourished individuals using the TBSignatureProfiler.

BACKGROUND: Gene expression signatures have been used as biomarkers of tuberculosis (TB) risk and outcomes. Platforms are needed to simplify access to these signatures and determine their validity in the setting of comorbidities. We developed a computational profiling platform of TB signature gene sets and characterized the diagnostic ability of existing signature gene sets to differentiate active TB from LTBI in the setting of malnutrition. METHODS: We curated 45 existing TB-related signature gene sets and developed our TBSignatureProfiler software toolkit that estimates gene set activity using multiple enrichment methods and allows visualization of single- and multi-pathway results. The TBSignatureProfiler software is available through Bioconductor and on GitHub. For evaluation in malnutrition, we used whole blood gene expression profiling from 23 severely malnourished Indian individuals with TB and 15 severely malnourished household contacts with latent TB infection (LTBI). Severe malnutrition was defined as body mass index (BMI) < 16 kg/m2 in adults and based on weight-for-height Z scores in children < 18 years. Gene expression was measured using RNA-sequencing. RESULTS: The comparison and visualization functions from the TBSignatureProfiler showed that TB gene sets performed well in malnourished individuals; 40 gene sets had statistically significant discriminative power for differentiating TB from LTBI, with area under the curve ranging from 0.662-0.989. Three gene sets were not significantly predictive. CONCLUSION: Our TBSignatureProfiler is a highly effective and user-friendly platform for applying and comparing published TB signature gene sets. Using this platform, we found that existing gene sets for TB function effectively in the setting of malnutrition, although differences in gene set applicability exist. RNA-sequencing gene sets should consider comorbidities and potential effects on diagnostic performance.

Medical students' perception of the educational environment in a tertiary care teaching hospital in India.

Background: The educational environment perceived by students has an impact on satisfaction with the course of study and academic achievement. We aimed to analyse the perceptions of medical students about their learning environment and to provide feedback to stakeholders involved in curriculum planning and execution. Methods: We did a cross-sectional descriptive study at Jawaharlal Institute of Postgraduate Medical Education and Research, Puducherry using the Dundee Ready Educational Environment Measure (DREEM) questionnaire. The DREEM inventory was administered to the undergraduate students of all semesters (n = 452). Students' perceptions of learning, perception about teachers, academic self-perceptions, perceptions of atmosphere and their social self-perceptions were measured. The scores obtained were expressed as mean (standard deviation) and analysed using t-test and 1-way ANOVA (with post-hoc comparison using Tukey test). The difference between semesters and gender was also analysed. Results: The mean (SD) global score was 122.06 (22.27), out of a maximum possible score of 200. Our students opined that teachers were knowledgeable, with this component scoring the maximum of 3.32 and, at the same time, they felt that teaching overemphasizes factual learning (1.41). Only 6 items scored <2. 'Students' perception of atmosphere' scored high among other domains (30 of 48, 62.5%). The mean global score of preclinical students (125.35 [20.43]) was better than clinical students (119.13 [23.44]; p = 0.003). Conclusion: Although the global score is more positive, we identified a few areas of concern such as overemphasis on factual learning, authoritarian teachers, the not-so-helpful existing learning strategies, vast curriculum (inability to memorize all), lack of supporting system for stressed out students and the boredom they felt in the course. These vital areas should be addressed by the stakeholders for the betterment of learning in the institute.

Predictors of delayed care seeking for tuberculosis in southern India: an observational study.

BACKGROUND: Reducing delay to accessing care is necessary to reduce the Tuberculosis (TB) burden in high incidence countries such as India. This study aimed to identify factors associated with delays in seeking care for TB in Southern India. METHODS: We analyzed data from newly diagnosed, smear-positive, culture-confirmed, pulmonary TB patients in the Regional Prospective Observational Research for TB (RePORT) cohort in Puducherry and Tamil Nadu, India. Data were collected on demographic characteristics, symptom duration, and TB knowledge, among other factors. Delay was defined as cough ≥4 weeks before treatment initiation. Risky alcohol use was defined by the AUDIT-C score which incorporates information about regular alcohol use and binge drinking. TB knowledge was assessed by knowing transmission mode or potential curability. RESULTS: Of 501 TB patients, 369 (73.7%) subjects delayed seeking care. In multivariable analysis, risky alcohol use was significantly associated with delay (aOR 2.20, 95% CI: 1.31, 3.68). Delay was less likely in lower versus higher income groups (<3000 versus >10,000 rupees/month, aOR 0.31, 95% CI: 0.12, 0.78). TB knowledge was not significantly associated with delay. CONCLUSIONS: Local TB programs should consider that risky alcohol users may delay seeking care for TB. Further studies will be needed to determine why patients with higher income delay in seeking care.

Brachial artery flow-mediated dilatation and carotid intima medial thickness in pediatric nephrotic syndrome: a cross-sectional case-control study.

BACKGROUND: Children with nephrotic syndrome (NS) have hyperlipidemia, which may lead to endothelial dysfunction. This study evaluated endothelial function and structural atherosclerosis in NS children with disease duration more than 2 years, by assessment of brachial artery flow-mediated dilatation (FMD) and carotid intima medial thickness (CIMT). METHODS: This is a cross-sectional case-control study recruiting 32 subjects aged 1-13 years with NS and 32 matched controls. Clinical details, FMD and CIMT were recorded. Lipid profile and oxidative stress were also analyzed in the subjects. RESULTS: The proportionate change in FMD was significantly lower in cases (5.65 ± 6.08 %) compared to controls (15.21 ± 9.41 %) (p < 0.01). No significant differences in CIMT were observed (p = 0.383). Blood malondialdehyde was significantly higher (p = 0.006) in the cases. Overall, 25 NS children (78 %) were in remission for more than 6 months, and in them, 9 (36 %) had deranged lipid profile. On stepwise linear regression, age of the patient was found to be a determinant of FMD (model R (2) = 18.9 %, p value = 0.048). CONCLUSION: The significantly low proportionate change in FMD in NS children suggests an ongoing process of endothelial dysfunction. Further studies are needed to confirm these findings. A long-term follow-up of children with NS may be required for identification of CIMT derangements.

Comparison of efficacy and safety of sublingual misoprostol with intracervical dinoprostone gel for cervical ripening in prelabour rupture of membranes after 34 weeks of gestation.

PURPOSE: To compare the efficacy and safety of sublingual misoprostol with intracervical dinoprostone gel for cervical ripening in prelabour rupture of membrane after 34 weeks of gestation. METHODS: One eighty-eight women having >34 weeks of gestation with PROM, singleton viable fetus and no prior caesarean section were randomized to sublingual misoprostol (50 µg every 4 h and maximum of 3 doses) and intracervical dinoprostone (0.5 mg every 2 h and maximum of 2 doses). Oxytocin augmentation was commenced in those with a satisfactory Bishop score, inadequate contractions and who did not go into spontaneous active labour. Primary outcome measures were induction-delivery interval and the number of women that went into spontaneous labour without oxytocin augmentation. RESULTS: There was a significant reduction in induction to delivery interval in sublingual misoprostol group compared to intracervical dinoprostone (8.3 ± 3.6 h vs 12.2 ± 6.6 h; p = 0.000). There was a significant reduction in duration of rupture of membrane to delivery interval (p = 0.015), 1st stage of labour (p = 0.000) in sublingual misoprostol group as compared to the intravaginal dinoprostone group. There was no difference observed in spontaneous vaginal delivery between the groups (0.919). Oxytocin requirement was significantly higher in the dinoprostone group p = 0.006). There were more maternal adverse effects of sublingual misoprostol (p = 0.026). However, maternal and neonatal safety profiles were comparable. CONCLUSIONS: Sublingual misoprostol and intracervical dinoprostone at the dose studied are equally efficacious in achieving spontaneous vaginal delivery, reduction in induction-delivery interval and in reducing the need for oxytocin, in women after 34 weeks gestation with rupture of membranes.

Socioepidemiologic profile and treatment-seeking behaviour of HIV/AIDS patients in a tertiary-care hospital in south India.

India has the third largest number of people living with HIV/AIDS. Provision of free antiretroviral therapy (ART) for eligible persons living with HIV (PLHA) has been scaled up significantly both in terms of facilities for treatment and number of beneficiaries. This study aimed at describing the profile of HIV/AIDS patients on ART from a tertiary-care hospital and to explore the factors associated with treatment-seeking behaviour, family support, and perceptions regarding HIV and ART. This is a descriptive study conducted at the ART centre in a tertiary-care hospital in Puducherry. Study population consisted of 130 HIV-positive patients aged more than 18 years on free firstline ART for at least 6 months. Data on sociodemographic details, clinical details, treatment-seeking behaviour, family support, and perceptions regarding HIV and ART were collected using a pretested questionnaire. Data are presented as percentages. In total, 130 patients on ART for at least 6 months were included in the study--61% were males (n=79), 39% were females (n=51); half of them belonged to the age-group of 36-50 years. Half of the participants were diagnosed to have HIV/AIDS between 1 and 3 year(s); two-thirds had one or more co-infection(s). The majority were aware of the side-effects of ART. After advice to start ART, there was a delay in starting treatment in one-fifth of the subjects due to depression, fear of stigma, disclosure to family, and side-effects. More than two-thirds of the patients travelled more than 30 km distance. Families of HIV-positive subjects were supportive in accompanying to the ART centre, collecting drugs, reminders to take medication, and motivation to complete the treatment. Alcohol (50%) and tobacco consumption (39%) was common among the subjects. Half of the respondents stated stigma, death, and pain as the main fears, and all of them stated high levels of trust and rapport with their doctors. This study reveals several positive aspects among ART beneficiaries. However, issues, like tobacco and alcohol consumption, travelling long distance for drug collection, fear of stigma and death, and concerns regarding the future, need to be addressed.

Traffic Noise Assessment in Urban Puducherry, South India.

Background Noise pollution is an emerging global problem that can affect people's well-being and mental and physical health. In India, six percent of people suffer hearing loss, and prolonged exposure leads to irreversible noise-induced hearing loss. Objective To assess the noise levels at selected residential, commercial, industrial, silence zones, traffic junctions, and related noise indices in urban Puducherry and compare them with Central Pollution Control Board (CPCB) standards. Methods The study was conducted using a cross-sectional noise survey based on the 2015 study sites in urban Puducherry using a sound level meter, analyzed the results with limits set by the CPCB standards, and calculated the various noise indices. Results In urban Puducherry, the noise level showing silence zones is more hazardous than industrial, residential, commercial, and traffic junctions. Out of the 36 sites surveyed, 33 locations are above the prescribed daytime limit by CPCB. Conclusions The noise assessment at selected sites in urban Puducherry shows that around 92% of study sites are well above the daytime standards of CPCB, highlighting an urgent need to curb noise levels. The findings revealed that increased noise at study sites could be due to the increased number of vehicles and transportation systems.

Prevalence of clustering of non-communicable disease risk factors in a highly urbanized district of India: findings of a cross-sectional survey in Puducherry.

Background: In an individual, the development and severity of Non-Communicable Diseases (NCDs) are determined by the presence or absence of clustering of NCD risk factors in them. We aimed to determine the prevalence and the factors associated with clustering of risk factors of NCDs in the district of Puducherry in India. Methodology: We conducted a community-based cross-sectional survey among the adult population (18-69 years) of Puducherry district (N = 1114) between February 2019 and February 2020. Ten risk factors of NCDs (behavioral, physical measurements and biochemical) were assessed. Individuals having ≥ 3 risk factors were regarded as having clustering of risk factors. Categorical variables are summarized using proportions (95% CI). Adjusted prevalence ratio was estimated using weighted forward stepwise generalized linear modelling. Results: Clustering of NCD risk factors was present in majority (95.2%, 95% CI: 93.8-96.3) of the population. The presence of clustering was significantly higher among women (97.1%, 95% CI: 95.9-98.3) and the urban population (97.2%, 95% CI: 96.1-98.3). The risk factors that primarily drove the high prevalence of clustering were raised salt intake and inadequate intake for fruits and vegetables in nine out of 10 people in the district. Nearly 1 in 10 (13.3%, 95% CI: 11.3-15.3), 1 in 5 (21.5%, 95% CI: 19.1-23.8) and 1 in 4 (26.8%, 95% CI: 24.1-29.4) participants had three, four and five risk factors, respectively. Conclusion: We highlight the urgent need for population-based health promotion interventions in the district of Puducherry targeting the highly prevalent NCD risk factors, especially among the women and urban populations.

Intestinal Parasitic Infections May Be Overlooked Drivers of the Tuberculosis Pandemic.

The burden of tuberculosis (TB) is disproportionate in tropical and subtropical regions, where parasitic coinfections are common. Given the significant geographical overlap between TB and intestinal parasitic infections, it is important to consider the implications of intestinal parasitic infections for the TB pandemic. Intestinal parasitic infections have been theorized to increase vulnerability to TB by altering the inflammatory milieu, inducing undernutrition that blunts the immune response, and affecting drug pharmacokinetics. In this perspective piece, we provide a background of the epidemiological and immunological evidence that links parasitic infections to increased risk of TB progression and worse treatment outcomes. We also identify gaps in our knowledge and call for increased research on TB-parasitic coinfections to ensure action on a potentially widespread TB comorbidity.

The hidden imbalance in neighbourhood nutrition environment: a perspective from lower-middle-income country setting.

Neighbourhood environment plays a pivotal role in determining the individual's nutrition through availability and accessibility of healthy food options. This community-based cross-sectional descriptive study examined neighbourhood spatial attributes using Geographical Information System (GIS) and describe perceived nutrition environment among adult residents in urban Puducherry, India. The density of grocery shops, fruits and vegetable shops, food outlets and restaurants were 64.4, 74.8 and 88.7 per km2, respectively. Out of 200 participants, 191 (95.5%) and 190 (95%) reported easy accessibility to fruits and vegetables shops and restaurants, respectively, while 192 (96%) agreed on availability of unhealthy food options in shops. Current study provides framework for assessment of objective and perceived neighbourhood nutrition environment in lower-middle-income countries with a user-friendly and easily administrable tool.

Deep learning classification of active tuberculosis lung zones wise manifestations using chest X-rays: a multi label approach.

Chest X-rays are the most economically viable diagnostic imaging test for active pulmonary tuberculosis screening despite the high sensitivity and low specificity when interpreted by clinicians or radiologists. Computer aided detection (CAD) algorithms, especially convolution based deep learning architecture, have been proposed to facilitate the automation of radiography imaging modalities. Deep learning algorithms have found success in classifying various abnormalities in lung using chest X-ray. We fine-tuned, validated and tested EfficientNetB4 architecture and utilized the transfer learning methodology for multilabel approach to detect lung zone wise and image wise manifestations of active pulmonary tuberculosis using chest X-ray. We used Area Under Receiver Operating Characteristic (AUC), sensitivity and specificity along with 95% confidence interval as model evaluation metrics. We also utilized the visualisation capabilities of convolutional neural networks (CNN), Gradient-weighted Class Activation Mapping (Grad-CAM) as post-hoc attention method to investigate the model and visualisation of Tuberculosis abnormalities and discuss them from radiological perspectives. EfficientNetB4 trained network achieved remarkable AUC, sensitivity and specificity of various pulmonary tuberculosis manifestations in intramural test set and external test set from different geographical region. The grad-CAM visualisations and their ability to localize the abnormalities can aid the clinicians at primary care settings for screening and triaging of tuberculosis where resources are constrained or overburdened.
