RESUMO
BACKGROUND & AIMS: Putative anion transporter-1 (PAT1, SLC26A6) plays a key role in intestinal oxalate and bicarbonate secretion. PAT1 knockout (PKO) mice exhibit hyperoxaluria and nephrolithiasis. Notably, diseases such as inflammatory bowel disease are also associated with higher risk of hyperoxaluria and nephrolithiasis. However, the potential role of PAT1 deficiency in gut-barrier integrity and susceptibility to colitis is currently elusive. METHODS: Age-matched PKO and wild-type littermates were administered 3.5% dextran sulfate sodium in drinking water for 6 days. Ileum and colon of control and treated mice were harvested. Messenger RNA and protein expression of tight junction proteins were determined by reverse transcription polymerase chain reaction and western blotting. Severity of inflammation was assessed by measuring diarrheal phenotype, cytokine expression, and hematoxylin and eosin staining. Gut microbiome and associated metabolome were analyzed by 16S ribosomal RNA sequencing and mass spectrometry, respectively. RESULTS: PKO mice exhibited significantly higher loss of body weight, gut permeability, colonic inflammation, and diarrhea in response to dextran sulfate sodium treatment. In addition, PKO mice showed microbial dysbiosis and significantly reduced levels of butyrate and butyrate-producing microbes compared with controls. Co-housing wild-type and PKO mice for 4 weeks resulted in PKO-like signatures on the expression of tight junction proteins in the colons of wild-type mice. CONCLUSIONS: Our data demonstrate that loss of PAT1 disrupts gut microbiome and related metabolites, decreases gut-barrier integrity, and increases host susceptibility to intestinal inflammation. These findings, thus, highlight a novel role of the oxalate transporter PAT1 in promoting gut-barrier integrity, and its deficiency appears to contribute to the pathogenesis of inflammatory bowel diseases.

INTRODUCTION: Burnout is an occupational phenomenon resulting from chronic workplace stress. We conducted this review to estimate the pooled global prevalence of burnout among the public health workforce. METHODS: We conducted this review as per the PRISMA 2020 guidelines. We included only cross-sectional studies reporting outcome estimates among the study population. We included articles published before December 2023. We used a search strategy to systematically select the articles from PubMed, Embase, and Google Scholar. We assessed the quality of the studies using an adapted version of NIH's study tool assessment for cross-sectional and observational cohort studies. We estimated the pooled proportion using the random-effects model. RESULTS: We included eight studies in our review, covering a sample size of 215,787. The pooled proportion of burnout was 39% (95% CI: 25-53%; p-value: < 0.001). We also identified high heterogeneity among the included studies in our review (I2: 99.67%; p-value: < 0.001). Seven out of the eight studies were of good quality. The pooled proportion of the studies conducted during the COVID-19 pandemic was 42% (95% CI: 17-66%), whereas for the studies conducted during the non-pandemic period, it was 35% (95% CI: 10-60%). CONCLUSION: In our review, more than one-third of public health workers suffer from burnout, which adversely affects individuals' mental and physical health. Burnout among the public health workforce requires attention to improve the well-being of this group. Multisite studies using standardized definitions are needed for appropriate comparisons and a better understanding of variations in burnout in various subgroups based on sociodemographic characteristics and type of work responsibilities. We must design and implement workplace interventions to cope with burnout and increase well-being. LIMITATIONS: Due to the limited research on burnout among public health workers, we could not perform a subgroup analysis on various factors that could have contributed to burnout.

INTRODUCTION: The India Hypertension Control Initiative (IHCI) emphasizes decentralized patient-centric care to boost hypertension control in public healthcare facilities. We documented the decentralization process, enrolment pattern by facility type, and treatment outcomes in nine districts of Punjab and Maharashtra states, India, from 2018-2022. METHODS: We detailed the shift in hypertension care from higher facilities to Health and Wellness Centres (HWCs) using the World Health Organization (WHO) health system pillar framework. We reviewed hypertension treatment records in 4,045 public facilities from nine districts in the two states, focusing on indicators including registration numbers, the proportion of controlled, uncontrolled blood pressure (BP), and missed visits among those under care. RESULTS: The decentralization process involved training, treatment protocol provision, supervision, and monitoring. Among 394,038 individuals registered with hypertension from 2018-2021, 69% were under care in 2022. Nearly half of those under care (129,720/273,355) received treatment from HWCs in 2022. Care of hypertensive individuals from district hospitals (14%), community health centres (20%), and primary health centres (24%) were decentralized to HWCs. Overall BP control rose from 20% (4,004/20,347) in 2019 to 58% (157,595/273,355) in 2022, while missed visits decreased from 61% (12,394/20,347) in 2019 to 26% (70,894/273,355) in 2022. This trend was consistent in both states. HWCs exhibited the highest BP control and the lowest missed visits throughout the study period compared to other facility types. CONCLUSION: We documented an increase in decentralized access to hypertension treatment and improved treatment outcomes over four years. We recommend operationalizing hypertension care at HWCs to other districts in India to improve BP control.

INTRODUCTION: Analysis of the coronavirus disease 2019 (COVID-19) surveillance system in the first wave indicated that the data-driven approach helped in resource allocation and public health interventions. OBJECTIVES: We described the epidemiology of COVID-19 cases in Chennai, Tamil Nadu, India, from February 2021 to February 2022. MATERIALS AND METHODS: We analyzed the COVID-19 surveillance data from Chennai City, Tamil Nadu, India's Greater Chennai Corporation. We described the deidentified line list of COVID-19 cases and deaths by months, zones, age, and gender. We estimated the incidence of COVID-19 cases per million population, test positivity rate (TPR), and case fatality ratio (CFR). RESULTS: Of the 434,040 cases reported in Chennai from February 1, 2021, to February 28, 2022, 53% were male. The incidence per million peaked in May 2021 (19,210) and January 2022 (15,881). Age groups more than 60 years reported maximum incidence. Southern region zones reported higher incidence. Overall TPR was 5.8%, peaked in May 2021 (17.5%) and January 2022 (15.1%). Over half of the 4929 reported deaths were in May 2021 (56%). Almost half of the deaths were 61-80 years (52%), followed by 41-60 years (26%). Overall CFR was 1%, which peaked in June 2021 (4%). CONCLUSION: We conclude that Chennai city experienced a surge in COVID-19 due to delta and omicron variants. Understanding descriptive epidemiology is vital for planning the public health response, resource allocation, vaccination policies, and risk communication to the community.

INTRODUCTION: India is facing a shortage of staff nurses; thus, a better understanding of nurses' workloads is essential for improving and implementing noncommunicable disease (NCD) control strategies. We estimated the proportion of time spent by staff nurses on hypertension and other NCD activities in primary care facilities in 2 states in India. METHODS: We conducted a cross-sectional study in 6 purposively selected primary care facilities in Punjab and Madhya Pradesh during July through September 2021. We used a standardized stopwatch to collect data for time spent on direct hypertension activities (measuring blood pressure, counseling, recording blood pressure measurement, and other NCD-related activities), indirect hypertension activities (data management, patient follow-up calls), and non-NCD activities. We used the Mann-Whitney U test to compare the median time spent on activities between facilities using paper-based records and the Simple mobile device-based app (open-source software). RESULTS: Six staff nurses were observed for 213 person-hours. Nurses spent 111 person-hours (52%; 95% CI, 45%-59%) on direct hypertension activities and 30 person-hours (14%; 95% CI, 10%-19%) on indirect hypertension activities. The time spent on blood pressure measurement (34 minutes) and documentation (35 minutes) was the maximum time on any given day. Facilities that used paper records spent more median time (39 [IQR, 26-62] minutes) for indirect hypertension activities than those using the Simple app (15 [IQR, 11-19] minutes; P < .001). CONCLUSION: Our study found that hypertension activities required more than half of nurses' time in India's primary care facilities. Digital systems can help to reduce the time spent on indirect hypertension activities.

BACKGROUND AND AIMS: Acute-on-chronic liver failure (ACLF) is associated with high short-term mortality in those with hepatic encephalopathy (HE). Polyethylene glycol (PEG) 3350 electrolyte solution can ensure rapid gut catharsis, which may resolve HE more effectively than lactulose. In this open-label-randomized trial, we compared PEG+lactulose versus lactulose alone in ACLF with HE grade ≥2 for efficacy and outcome. PATIENTS AND METHODS: Patients were randomized to receive PEG (2 L q12 h) followed by lactulose (30 mL q8 h) or standard medical treatment [SMT, lactulose (titrated 30 mL q8 h)]. Endpoints were HE grade improvement at 24 hours, 48 hours, and 7 days using hepatic encephalopathy scoring algorithm (HESA), ammonia reduction, HE resolution, and survival benefit. RESULTS: Of 60 patients, 29 were randomized to PEG+lactulose arm and 31 to SMT. In the PEG arm, early reduction in HESA score was noted in more persons [18 (62.1%) vs. 10 (32.2%); P=0.021] with a shorter median time to HE resolution [4.5 (3 to 9) d vs. 9 (8 to 11) d; P=0.023]. On multivariate analysis, age [hazard ratio (HR),1.06 (1.00 to 1.13); P=0.03], HESA score [HR, 6.01 (1.27 to 28.5); P=0.024], and model for end-stage liver disease [HR, 1.26 (1.01 to 1.53); P=0.022] were predictors of mortality at 28 days. Ammonia level or reduction did not correlate with HE grades. Adverse events included excessive diarrhea (20.6% vs. 9.6%) in the PEG and SMT arms, albeit without dyselectrolytemia or worsened renal function. In the PEG versus SMT arm, survival at 28 days were 93.1% versus 67.7% (P=0.010) and at 90 days was 68.9% versus 48.3% (P=0.940), respectively, with fewer persons relapsing with HE in the PEG arm. CONCLUSIONS: PEG resulted in early and sustained HE resolution with improved short-term survival making, it a suitable and safe drug in patients with acute HE in ACLF.

Background & objectives: Non-communicable diseases (NCDs) are the leading cause of death in India. Although studies have reported a high prevalence of NCD in tribal populations, there are limited data pertaining mortality due to NCDs. Therefore, in this study we estimated the proportion of deaths due to NCDs among 15 yr and older age group in tribal districts in India. Methods: We conducted a community-based survey in 12 districts (one per State) with more than 50 per cent tribal population. Data were collected using a verbal autopsy tool from the family member of the deceased. The estimated sample size was 452 deaths per district. We obtained the list of deaths for the reference period of one year and updated it during the survey. The cause of death was assigned using the International Classification of Diseases-10 classification and analyzed the proportions of causes of death. The age-standardized death rate (ASRD) was also estimated. Results: We surveyed 5292 deaths among those above 15 years of age. Overall, NCDs accounted for 66 per cent of the deaths, followed by infectious diseases (15%) and injuries (11%). Cardiovascular diseases were the leading cause of death in 10 of the 12 sites. In East Garo Hills (18%) and Lunglei (26%), neoplasms were the leading cause of death. ASRD due to NCD ranged from 426 in Kinnaur to 756 per 100,000 in East Garo Hills. Interpretation & conclusions: The findings of this community-based survey suggested that NCDs were the leading cause of death among the tribal populations in India. It is hence suggested that control of NCDs should be one of the public health priorities for tribal districts in India.

Background and objectives: Non-communicable diseases (NCDs) are highly prevalent in the tribal populations; however, there are limited data regarding health system preparedness to tackle NCDs among these populations. We estimated the availability of human resources, equipment, drugs, services and knowledge of doctors for NCD management in the selected tribal districts in India. Methods: A cross-sectional survey was conducted in 12 districts (one from each State) with at least 50 per cent tribal population in Andaman and Nicobar Islands, Himachal Pradesh, Madhya Pradesh, Odisha and eight northeastern States. Primary health centres (PHCs), community health centres (CHCs) and district/sub-district hospitals (DHs) were surveyed and data on screening and treatment services, human resources, equipment, drugs and information systems indicators were collected and analysed. The data were presented as proportions. Results: In the present study 177 facilities were surveyed, including 156 PHCs/CHCs and 21 DHs. DHs and the majority (82-96%) of the PHCs/CHCs provided outpatient treatment for diabetes and hypertension. Overall, 97 per cent of PHCs/CHCs had doctors, and 78 per cent had staff nurses. The availability of digital blood pressure monitors ranged from 35 to 43 per cent, and drugs were either not available or inadequate. Among 213 doctors, three-fourths knew the correct criteria for hypertension diagnosis, and a few correctly reported diabetes diagnosis criteria. Interpretation & conclusions: The results of this study suggest that the health system of the studied tribal districts was not adequately prepared to manage NCDs. The key challenges included inadequately trained workforce and a lack of equipment and drugs. It is suggested that capacity building and, procurement and distribution of equipment, drugs and information systems to track NCD patients should be the key focus areas of national programmes.

BACKGROUND: Mosquito coil smoke, along with biomass fuel smoke, are sources of indoor air pollution. Biomass fuel smoke has been studied as a risk factor for poor respiratory outcomes. However, in an Indian context, few studies examine the effect of mosquito coil exposure on poor respiratory outcomes at the community level. OBJECTIVES: To estimate the prevalence of the biomass fuel and mosquito coil use and to determine the association between the use of bio-mass fuel and mosquito coil and poor respiratory health. METHODS: A cross-sectional survey of 4662 individuals (above the age of 30 years) was conducted using a pre-tested questionnaire. Trained interviewers collected data on current and past use of biomass fuels and mosquito coils, usage practices and respiratory health. We computed proportions for exposure variables namely biomass fuel, mosquito coil use and other covariates. We conducted univariate analysis, followed by multivariate logistic regression. RESULTS: The prevalence of ever use of biomass fuels was high (wood: 97.9%; cow dung cake: 76.0% and crop residue: 54.4%). Current use of wood, cow dung cake and crop residue was prevalent among 75.7, 24.3 and 30.9% respondents, respectively. Almost 70% of respondents had ever used mosquito coils, whereas 54% were current users. Overall, 5.5% respondents had poor respiratory health either due to chronic bronchitis or asthma. In multivariate analysis, use of combination of all three biomass fuel types (adjusted odds ratio [AOR] 1.69, 95% confidence interval [CI]: 1.13-2.54) and use of mosquito coil more than or equal to 5 days per week (AOR 1.43, 95% CI: 1.04-1.99) were associated with poor respiratory health after adjusting for covariates age, gender, smoking, kitchen type and for each other. CONCLUSIONS: Use of biomass fuels and mosquito coils was high in the study population and was associated with poor respiratory health. Therefore, mosquito coil smoke should also be considered an important source of indoor air pollution, similar to biomass fuel exposure. Community education about these sources of indoor air pollution and increased coverage of cleaner fuels and alternative mosquito control methods should be the way forward in the rural areas.

Efforts are being made to scale up human papillomavirus (HPV) vaccination for adolescent girls in India. Bivalent and quadrivalent HPV vaccines were licensed in the country in 2008, and a nonavalent vaccine was licensed in 2018. Demonstration projects initiated in Andhra Pradesh and Gujarat in 2009 introduced HPV vaccination in public health services in India. Following a few deaths in these projects, although subsequently deemed unrelated to vaccination, HPV vaccination in research projects was suspended. This suspension by default resulted in some participants in a trial evaluating two versus three doses receiving only one dose. Since 2016, the successful introduction of HPV vaccination in immunisation programmes in Punjab and Sikkim (with high coverage and safety), government-sponsored opportunistic vaccination in Delhi, prospects of a single dose providing protection, and future availability of an affordable Indian vaccine shows promise for future widespread implementation and evaluation of HPV vaccination in India.

Background: Non-communicable diseases (NCDs) are the leading cause of mortality in India. The northeastern part of India has a high burden of NCDs. However, data on the prevalence of risk factors for NCDs in the rural tribal population of Nagaland are limited. We estimated the prevalence and awareness level of risk factors for NCDs in the rural population of Mokokchung district, Nagaland. Methods: In a cross-sectional survey, we selected 472 subjects aged 25-64 years, stratified by age and sex, in 20 villages, using a cluster sampling technique. The WHO STEPS tools were used to collect data on behavioural risk factors, and anthropometric, blood pressure and capillary glucose measurements. The proportion of subjects with each NCD risk factor was determined overall and in various age and sex subgroups. Results: The 472 subjects had a median age of 44.5 years, 92 (19.5%) reported current smoking and 75 (15.9%) reported current alcohol use. Among 236 males, 90 (38.1 %) were current smokers and 65 (27.5%) were current alcohol users, whereas of the 236 females, only 2 (0.8%) and 10 (4.2%) were current smokers and current alcohol users, respectively. The use of smokeless tobacco was common among both males (139/236; 58.9%) and females (117/ 236; 49.6%). Inadequate intake of fruits and vegetables was reported by 189 (80.1%) males and 221 (93.6%) females. Insufficient physical activity was observed only among 16 (3.4%) participants. Prevalence of hypertension and a body mass index of 23.0-27.49 kg/m2 was 43.2% and 32.4%, respectively. Conclusions: We observed a high prevalence of behavioural risk factors for NCDs and of hypertension in rural tribal people in Nagaland. The primary healthcare system needs to be strengthened in this area to improve detection and management of hypertension. Mass and print media campaigns and provision of cessation services may also be helpful.

BACKGROUND: India has a high burden of diabetic retinopathy ranging from 12.2% to 20.4% among patients with type 2 diabetes mellitus (T2DM). A T2DM management programme was initiated in the public sector in Tamil Nadu. We estimated the prevalence of diabetic retinopathy and its associated risk factors. METHODS: We did a cross-sectional survey among patients with T2DM attending two primary health centres for treatment and follow-up in Kancheepuram, Tamil Nadu in January- March 2013. We did a questionnaire-based survey, and measured blood pressure and biochemical parameters (serum creatinine, plasma glucose, etc.) of the patients. We examined their eyes by direct and indirect ophthalmoscopy and defined diabetic retinopathy using a modified classification by Klein et al. We calculated the proportion and 95% CI for the prevalence and adjusted odds ratio (AOR) for risk factors associated with diabetic retinopathy. RESULTS: Among the 270 patients, the mean (SD) age was 54.5 (10) years. The median duration of T2DM was 48 months. The prevalence of diabetic retinopathy was 29.6%. Overall, 65.9% of patients had hypertension, 14.4% had nephropathy (eGFR <60 mg/dl) and 67.4% had neuropathy. Among patients with comorbid conditions, 60%, 48%, 32%, and 3% were already diagnosed to have hypertension, neuropathy, retinopathy, and nephropathy, respectively. The risk factors for diabetic retinopathy were hypertension (AOR 3.2, 95% CI 1.7-6.3), duration of T2DM >5 years (AOR 6.5, 95% CI 3.6-11.7), poor glycaemic control (AOR 2.4, 95% CI 1.4-4.4), and nephropathy (AOR 2.3, 95% CI 1.1-4.6). CONCLUSIONS: There was a high burden of undetected retinopathy and other comorbid conditions among patients with T2DM. Early detection of comorbid conditions and glycaemic control can be improved by training care-providers and educating patients.

Hypertension is a public health problem with low detection and treatment rates in India. We resurveyed 1284 patients with hypertension already identified in baseline survey of the cohort in Thiruvallur district, Tamil Nadu, India. The objective was to estimate the proportion of patients with drug treatment, hypertension control and lifestyle modification at follow-up (median follow-up 27 months). Overall, only 19.9% of the patients took drugs and 45.3% had blood pressure under control. Among 256 patients on drugs, 179 (69.9%) were on a single drug, 71 (27.7%) on two drugs, and six (2.3%) on three drugs. Commonly prescribed drugs based on the prescription review were beta blockers (50.4%), calcium channel blockers (36.7%), angiotensin-converting-enzyme inhibitor (18.4%), and diuretics (11.7%). Salt reduction was reported by 49.7% of the patients. There is a need for strengthening the health systems for effective management of hypertension and patient education to ensure active involvement in the long-term care.

Public health research has several stakeholders that should be involved in identifying public health research agenda. A survey was conducted prior to a national consultation organized by the Department of Health Research with the objective to identify the key public health research priorities as perceived by the State health officials and public health researchers. A cross-sectional survey was done for the State health officials involved in public health programmes and public health researchers in various States of India. A self-administered semi-structured questionnaire was used for data collection. Overall, 35 State officials from 15 States and 17 public health researchers participated in the study. Five leading public health research priorities identified in the open ended query were maternal and child health (24%), non-communicable diseases (22%), vector borne diseases (6%), tuberculosis (6%) and HIV/AIDS/STI (5%). Maternal and child health research was the leading priority; however, researchers also gave emphasis on the need for research in the emerging public health challenges such as non-communicable diseases. Structured initiatives are needed to promote interactions between policymakers and researchers at all stages of research starting from defining problems to the use of research to achieve the health goals as envisaged in the 12th Plan over next five years.

BACKGROUND: Smoking tobacco affects the health of smokers as well as non-smokers who are exposed to secondhand smoke. The Government of India enacted the Cigarettes and Other Tobacco Products Act in 2003, which included a ban on smoking in public places and on sale of tobacco around educational institutions. We assessed the extent of compliance with these laws in restaurants and educational institutions in Chennai, Tamil Nadu, India. METHODS: We conducted a cross-sectional survey using an observation checklist in restaurants and educational institutions in Chennai. We used cluster sampling for restaurants and random sampling for schools and colleges. We collected data regarding the signage displaying prohibition of smoking as per the law and sale of tobacco products around educational institutions. We estimated the proportions for various indicators. RESULTS: Among the 400 restaurants surveyed, 371 (92.8%) did not have any signage displaying prohibition of smoking and of the 29 restaurants with signage, only 4 were as per the specifications. There were 62 (15.5%) smoking events in restaurants at the time of visit for survey. Among the 287 schools surveyed, only 8 (2.8%) had the signage displaying prohibition of smoking and 2 (0.7%) had the signage for ban on sale of tobacco products. Of the 54 colleges surveyed, 8 (14.8%) had the signage displaying prohibition of smoking and 7 (13%) had the signage for ban on sale of tobacco products. CONCLUSION: There was low compliance of smoke-free laws in restaurants and educational institutions in Chennai. We recommend a robust monitoring mechanism to ensure the enforcement of smoke-free laws in public places.

Globally, 1 billion people live in slums. There are few reports of high prevalence of noncommunicable disease (NCD) risk factors among the urban poor. The prevalence of NCD risk factors in the slums in North 24 Parganas, West Bengal, India was estimated. Cross-sectional survey in 24 slums selected using cluster sampling method was conducted. Questionnaire for behavioral risk factors was used and anthropometric and blood pressure measurements were done. The study population included 1052 participants aged 25-64 years, 528 (50%) were males. Among males, 206 (39%) were current smokers and 154 (29%) were current alcohol users. Central obesity was prevalent among 32.8% males and 56.1% females and 115 (10.9%) had body mass index ≥27.5 kg/m 2 . Hypertension was prevalent among 35% males and 33% females. We observed high prevalence of NCD risk factors among urban slum dwellers that need to be addressed with health promotion programs and strengthening of primary health care system.

Diagnosis of TB at early stages of HIV infection may lead to timely intervention for improving patient outcome. Antibodies to Mycobacterium tuberculosis recombinant RpfB protein and two immunodominant peptides of Rpf B protein were evaluated in the sera of HIV +TB+, HIV+ and HIV- pulmonary TB patients by ELISA. Serum antibodies from 90 % and 65 % of HIV+TB+ patients reacted to recombinant RpfB protein and synthetic peptide RpfP1 respectively. Overall, this study shows that resuscitation promoting factor B elicits humoral antibody response in HIV+TB+ co-infected individuals and be proposed as a potential biomarker for diagnosis of HIV+TB+ patients, however further longitudinal follow up studies are warranted.

The nucleic acid amplification tests (NAATs) such as Xpert MTB/RIF have transformed the TB diagnostic field by significantly increasing the case detection. However, newer improved diagnostic assays are still needed to meet the WHO targets to end TB. Present study is based on a novel approach of utilizing the in-vivo expressed specific mycobacterial transcriptomic biomarkers for the diagnosis of pulmonary tuberculosis (PTB). Total 61 subjects were recruited including smear positive (smear+; n = 15), smear negative (smear-; n = 30) PTB patients and disease controls (n = 16). Transcripts of three mycobacterial genes Rv0986, Rv0971c and Rv3121 were analyzed using real time PCR (qRT-PCR) in sputum samples. qRT-PCR with Rv0986, Rv0971c and Rv3121 identified smear + PTB patients with 100 %, 78.6 % and 86.7 % sensitivity respectively. In smear- PTB patients, both Rv0986 and Rv0971c based qRT-PCR resulted in 63 %, sensitivity whereas Rv3121 identified these patients with â¼40 % sensitivity only. The sensitivity of the assay for smear-patients increased to 85 % when combinatorial analysis of qRT-PCR data for all the three genes was used. Thus, in-vivo expressed mycobacterial transcripts have promising potential as biomarkers for PTB diagnosis.
