Diabetes is associated with increased liver cancer incidence and mortality in adults: A report from Asia Cohort Consortium.

There has been growing evidence suggesting that diabetes may be associated with increased liver cancer risk. However, studies conducted in Asian countries are limited. This project considered data of 968,738 adults pooled from 20 cohort studies of Asia Cohort Consortium to examine the association between baseline diabetes and liver cancer incidence and mortality. Cox proportional hazard model and competing risk approach was used for pooled data. Two-stage meta-analysis across studies was also done. There were 839,194 subjects with valid data regarding liver cancer incidence (5654 liver cancer cases [48.29/100,000 person-years]), follow-up time and baseline diabetes (44,781 with diabetes [5.3%]). There were 747,198 subjects with valid data regarding liver cancer mortality (5020 liver cancer deaths [44.03/100,000 person-years]), follow-up time and baseline diabetes (43,243 with diabetes [5.8%]). Hazard ratio (HR) (95% confidence interval [95%CI]) of liver cancer diagnosis in those with vs. without baseline diabetes was 1.97 (1.79, 2.16) (p < .0001) after adjusting for baseline age, gender, body mass index, tobacco smoking, alcohol use, and heterogeneity across studies (n = 586,072; events = 4620). Baseline diabetes was associated with increased cumulative incidence of death due to liver cancer (adjusted HR (95%CI) = 1.97 (1.79, 2.18); p < .0001) (n = 595,193; events = 4110). A two-stage meta-analytic approach showed similar results. This paper adds important population-based evidence to current literature regarding the increased incidence and mortality of liver cancer in adults with diabetes. The analysis of data pooled from 20 studies of different Asian countries and the meta-analysis across studies with large number of subjects makes the results robust.

Post COVID-19 vaccination medium vessel vasculitis: a systematic review of case reports.

PURPOSE: Vaccinations are essential in minimizing the effects of global health crises including COVID-19 pandemic. This study investigates the potential association between COVID-19 vaccination and the occurrence of medium vessel vasculitis. METHODS: Several databases were utilized to conduct a comprehensive literature review. The studies were carefully evaluated to ensure their quality and eliminate any potential bias. RESULTS: After reviewing 935 search results and removing duplicates, we selected 10 case reports. We discovered that medium vessel vasculitis may occur after COVID-19 vaccination, typically appearing around 16.2 days after vaccination. The patients in the study had a median age of 43.5 years and were predominantly males (80%). Additionally, half of the cases were reported after the second dose of vaccination. CONCLUSIONS: Vaccination-associated vasculitis is a rare yet possible complication of COVID-19 vaccination and lacks a clear treatment protocol.

Microbiology proficiency testing in fish and fishery products: detection of Listeria monocytogenes and Salmonella spp.

This paper presents the results of two proficiency testing (PT) rounds conducted by the Export Inspection Agency (EIA) Chennai laboratory in 2021 for food testing laboratories in India. The PT program was designed in accordance with ISO/TS 22117, a standard for proficiency testing in food microbiology, and targeted Listeria monocytogenes and Salmonella spp as the organisms of focus. The samples were found to be stable and recoverable during the analysis, and all PT sample packages were delivered to participant laboratories in good condition. The participant laboratories reported high sensitivity rates of 100% for PT round 061021 M and 96.49% for PT round 050721 M. The accuracy rate in PT round 061021 M was 91.89% and 92.10% in case of PT round 050721 M. However, there were some false positive and false negative results reported by some participant laboratories in both PT rounds, which may have been caused by operational errors or inconsistencies in analysis. During the PT round 061021 M, out of a total of 38 participant laboratories, five laboratories reported false positive results and one laboratory reported a false negative result. Similarly, during the PT round 050721 M, six laboratories reported false positive results which resulted in their results being deemed unsatisfactory.

Evaluation of the effectiveness of the Indian government's policies to strengthen health warning labels on smokeless tobacco products: findings from the 2010-2019 Tobacco Control Project India Surveys.

BACKGROUND: Smokeless tobacco (SLT) packaging in India had a single symbolic (a scorpion) health warning label (HWL) in 2009 covering 40% of the front surface. In 2011, it was replaced with four pictorial images. In 2016, HWLs were enlarged to 85% on the front and back. This study aimed to assess the effectiveness of the old (symbolic and smaller images) and larger HWLs. METHODS: Data were from the Tobacco Control Project India Survey and included respondents who used SLT in Wave 1 (2010-2011, n=5911), Wave 2 (2012-2013, n=5613) and Wave 3 (2018-2019, n=5636). Using a repeated-measures design, weighted logistic regression models assessed whether there were changes in seven HWL effectiveness measures within the domains of awareness, salience, cognitive and behavioural responses. A cohort design was employed to test whether HWL effectiveness in Waves 1 and 2 was associated with quitting SLT in Waves 2 and 3, respectively. RESULTS: The 2011 HWL revision did not result in any significant changes in HWL effectiveness. There was no significant change in HWL awareness and salience after larger HWLs were introduced in 2016, but respondents were more likely to consider SLT health risks (Wave 2=17.9%, Wave 3=33.6%, p<0.001) and quitting SLT (Wave 2=18.9%, Wave 3=36.5, p<0.001). There was no change in HWLs stopping SLT use (Wave 2=36.6%, Wave 3=35.2%, p=0.829); however, respondents were more likely to avoid looking at HWLs (Wave 2=10.1%, Wave 3=40.2%, p<0.001). Effectiveness of older, symbolic and smaller pictorial HWLs was not associated with quitting SLT. DISCUSSION: There was no significant change in HWL effectiveness following the revision from a symbolic to a pictorial image, but enlarging pictorial images resulted in some improved cognitive and behavioural effects. Results suggested wear-out of HWL salience and that the effectiveness of warnings depends on both their design and time since implementation.

Obesity is associated with biliary tract cancer mortality and incidence: A pooled analysis of 21 cohort studies in the Asia Cohort Consortium.

Body fatness is considered a probable risk factor for biliary tract cancer (BTC), whereas cholelithiasis is an established factor. Nevertheless, although obesity is an established risk factor for cholelithiasis, previous studies of the association of body mass index (BMI) and BTC did not take the effect of cholelithiasis fully into account. To better understand the effect of BMI on BTC, we conducted a pooled analysis using population-based cohort studies in Asians. In total, 905 530 subjects from 21 cohort studies participating in the Asia Cohort Consortium were included. BMI was categorized into four groups: underweight (<18.5 kg/m2 ); normal (18.5-22.9 kg/m2 ); overweight (23-24.9 kg/m2 ); and obese (25+ kg/m2 ). The association between BMI and BTC incidence and mortality was assessed using hazard ratios (HR) and 95% confidence intervals (CIs) by Cox regression models with shared frailty. Mediation analysis was used to decompose the association into a direct and an indirect (mediated) effect. Compared to normal BMI, high BMI was associated with BTC mortality (HR 1.19 [CI 1.02-1.38] for males, HR 1.30 [1.14-1.49] for females). Cholelithiasis had significant interaction with BMI on BTC risk. BMI was associated with BTC risk directly and through cholelithiasis in females, whereas the association was unclear in males. When cholelithiasis was present, BMI was not associated with BTC death in either males or females. BMI was associated with BTC death among females without cholelithiasis. This study suggests BMI is associated with BTC mortality in Asians. Cholelithiasis appears to contribute to the association; and moreover, obesity appears to increase BTC risk without cholelithiasis.

Anteromedial Petrous (Gardner's) Triangle: Surgical Anatomy and Relevance for Endoscopic Endonasal Approach to the Petrous Apex and Petroclival Region.

BACKGROUND AND OBJECTIVES: Triangular corridors have been used as reliable surgical entry points for open transcranial approaches to the petrous apex (PA) and petroclival region (PCR). The endoscopic endonasal approaches have grown rapidly in the last decade, and the indications have advanced. The knowledge of accurate and reliable anatomic landmarks through endoscopic endonasal route is essential and remain to be established. The purpose of this study was to describe the feasibility and surgical exposure of the anteromedial petrous (Gardner's) triangle as a novel corridor to the PA and PCR. METHODS: Five anatomic specimens were dissected. The PA and PCR were accessed through endoscopic endonasal approaches and contralateral transmaxillary approach. The limits of the anteromedial petrous (Gardner's) triangle were identified and dissected and associated measurements performed. RESULTS: The dissection was divided into 6 steps. The limits of the anteromedial petrous (Gardner's) triangle were identified and defined by the paraclival internal carotid artery anterolaterally, the abducens nerve posteromedially, and the petroclival synchondrosis inferiorly. Three lines were established following the limits of the triangle. The mean distance of the anterolateral limit was 10.03 mm (SD = 0.94), of the posteromedial limit was 20.06 mm (SD = 2.90), and of the inferior limit was 17.99 mm (SD = 2.99). The mean area was 87.56 mm 2 (SD = 20.06). The 3 anatomic landmarks with a critical role to safely define the triangle were the pterygosphenoidal fissure, the petrosal process of the sphenoid bone, and the petroclival synchondrosis. CONCLUSION: The anteromedial (Gardner's) triangle is a well-defined bone corridor which provides access to the entire petrous bone and petroclival junction through endoscopic endonasal route. Regardless of the anatomic variations or tumor location, the landmarks of the abducens nerve, paraclival internal carotid artery, and petroclival synchondrosis are key for understanding lateral access to tumors extending from the clivus.

The Burden and Correlates of Waterpipe (Hookah) Smoking among Adolescents and Youth: A Systematic Review.

BACKGROUND: This systematic review evaluated the available medical literature on the prevalence and trends of waterpipe tobacco smoking among adolescents and youth in jurisdictionally representative populations. METHODS: PubMed, Embase, and Scopus were searched for relevant studies from inception until 31 December 2022 that reported the burden of waterpipe smoking among adolescents and youth (10-24 years of age). We extracted qualitative data on the demographic characteristics, burden, and correlates of waterpipe smoking (PROSPERO ID: CRD42022310982). RESULTS: A total of 2,197 articles were screened and 62 were included in the analysis. The majority (29) of the studies was from the United States of America and there were no studies from the south-east Asian region. The prevalence of ever waterpipe smoking among the 10-24 years age group was noted to be 18.16% (95% CI, 18.03-18.29). The prevalence of current (30-day) waterpipe smoking was 6.43% (95% CI, 6.34-6.50). The age of initiation of waterpipe smoking was variable. The prevalence of waterpipe smoking was higher among males, among those who belong to the high- and middle-income groups, and among university students. The common risk factors of waterpipe smoking included cigarette smoking, alcohol, and substance use. Waterpipe smoking resulted in increased susceptibility to the use of conventional forms of tobacco (e.g. smoking) among those who were never smokers. CONCLUSION: Waterpipe smoking usage was significantly high among adolescents and young adults. Developing regulatory guidelines for water-pipe smoking, surveillance of its use, intervention, and specific policy frameworks may be considered a public health priority.

Unveiling the relationship between gut microbiota and heart failure: Recent understandings and insights.

Gut microbiota, which comprises a broad range of bacteria inhabiting the human intestines, plays a crucial role in establishing a mutually beneficial relationship with the host body. Dysbiosis refers to the perturbations in the composition or functioning of the microbial community, which can result in a shift from a balanced microbiota to an impaired state. This alteration has the potential to contribute to the development of chronic systemic inflammation. Heart failure (HF) is a largely prevalent clinical condition that has been demonstrated to have variations in the gut microbiome, indicating a potential active involvement in the pathogenesis and advancement of the disease. The exploration of the complex interplay between the gut microbiome and HF presents a potential avenue for the discovery of innovative biomarkers, preventive measures, and therapeutic targets. This review aims to investigate the impact of gut bacteria on HF.

Upscaling a behavioural intervention program for tobacco use cessation - A randomised controlled study.

A randomised control trial was conducted among school teachers in Bihar, India for upscaling a tested, evidence-based tobacco intervention using train-the-trainer model. Six blocks in three districts were selected and randomised into intervention and control blocks. Cluster coordinators in intervention blocks were given training in the details of intervention. Cluster coordinators routinely train headmasters and they were asked to include intervention training in their routine. Except for the training material, no additional resources were provided to cluster coordinators and headmasters. Headmasters implemented the intervention along with the teachers in the school. Post-intervention random sample of 70 schools out of 219 schools from intervention blocks and 70 schools out of 224 schools in control blocks were surveyed. The survey was self-administered among 429 school teachers in intervention schools and 331 among control schools. For all 140 headmasters, the survey was interviewer administered. Almost all headmasters in intervention schools had attended the training and had involved teachers in the intervention program. Odds ratios for carrying out the recommended activities in intervention schools compared to control schools were very high and significant. In addition, intervention schools also conducted activities such as including intervention messages in classroom teaching and conveying them to parents, activities that were not directly recommended in intervention program. Thus, this train-the-trainer model demonstrated that it is possible to upscale the intervention programs successfully with the resources within the system.

Lung Cancer Risk Prediction Models for Asian Ever-Smokers.

INTRODUCTION: Although lung cancer prediction models are widely used to support risk-based screening, their performance outside Western populations remains uncertain. This study aims to evaluate the performance of 11 existing risk prediction models in multiple Asian populations and to refit prediction models for Asians. METHODS: In a pooled analysis of 186,458 Asian ever-smokers from 19 prospective cohorts, we assessed calibration (expected-to-observed ratio) and discrimination (area under the receiver operating characteristic curve [AUC]) for each model. In addition, we developed the "Shanghai models" to better refine risk models for Asians on the basis of two well-characterized population-based prospective cohorts and externally validated them in other Asian cohorts. RESULTS: Among the 11 models, the Lung Cancer Death Risk Assessment Tool yielded the highest AUC (AUC [95% confidence interval (CI)] = 0.71 [0.67-0.74] for lung cancer death and 0.69 [0.67-0.72] for lung cancer incidence) and the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial Model had good calibration overall (expected-to-observed ratio [95% CI] = 1.06 [0.90-1.25]). Nevertheless, these models substantially underestimated lung cancer risk among Asians who reported less than 10 smoking pack-years or stopped smoking more than or equal to 20 years ago. The Shanghai models were found to have marginal improvement overall in discrimination (AUC [95% CI] = 0.72 [0.69-0.74] for lung cancer death and 0.70 [0.67-0.72] for lung cancer incidence) but consistently outperformed the selected Western models among low-intensity smokers and long-term quitters. CONCLUSIONS: The Shanghai models had comparable performance overall to the best existing models, but they improved much in predicting the lung cancer risk of low-intensity smokers and long-term quitters in Asia.

Tuberculosis manifesting with significant peripheral eosinophilia: A case report and review of literature.

Key Clinical Message: Peripheral eosinophilia is a rare but potential sign of TB infection. Physicians should assess patients for TB, especially if they display related symptoms or risk factors, and consider TB as a differential diagnosis, especially in idiopathic cases. Abstract: Millions of new tuberculosis (TB) cases are reported annually. Peripheral eosinophilia is rare in tuberculosis. We describe a rare case of tuberculosis with a high peripheral eosinophil count. A 9-year-old male presented with fever, cough, and respiratory discomfort for a month. The patient's cough did not respond to treatment, along with weight loss and a loss of appetite. A physical examination revealed cervical lymphadenopathy and bilateral lung crepitations. A hematological investigation showed a high eosinophil count of 25,920 cells per cubic millimeter and medical imaging abnormalities consistent with TB. Some malignancies, allergies, and parasitic infections produce peripheral eosinophilia. However, medical literature rarely discusses TB-induced eosinophilia. Several studies attribute it to mycobacterium antigen hyperreactivity. Eosinophilic release of cytotoxic chemicals may cause tissue damage, and TB patients' eosinophil levels may fluctuate. This case report emphasizes the need to investigate TB in peripheral eosinophilia patients after ruling out other explanations. Our patient benefited from early detection and anti-TB medication. More studies are required to investigate the causes of TB eosinophilia and its consequences. A detailed medical history and physical examination are essential to diagnose and treat atypical presentations of TB.

Erasmus syndrome: A rare case report of silicosis and systemic sclerosis.

People with silicosis may develop Erasmus syndrome, a condition characterized by the emergence of systemic sclerosis (SSc) after silica exposure. This case study emphasizes the significance of understanding the connection between occupational silica exposure, silicosis, and SSc. A 24-year-old male stonecutter got silicosis and a form of SSc following 8 years on his job as a stonecutter. The signs and symptoms the patient experienced were Raynaud's phenomenon, cutaneous fibrosis, arthralgia, digital pitting, and respiratory distress. High-resolution computed tomography (HRCT) revealed interstitial lung disease and calcified mediastinal lymph nodes. This case study demonstrates the clinical importance of the relationship between occupational silica exposure, silicosis, SSc, and Erasmus syndrome. Healthcare providers need to be aware of the possible difficulties and issues that may result from silica exposure. They should prioritize quick detection and efficient treatment plans for those who have been exposed to silica while on the job.

Awareness and Use of e-cigarettes among Adolescents and Their Adult Caregivers in Two Cities of India.

INTRODUCTION/OBJECTIVE: E-cigarette use poses an additional risk for individuals who are not cigarette smokers, especially adolescents. The marketing tactics of the industry have substantially increased the prevalence of e-cigarettes, use among adolescents. India banned e-cigarette in September 2019 that has been criticized by interested groups.  We investigated that among adults and adolescents, who are more aware and using e-cigarette more? METHODS: The data were taken from a population-based representative household survey conducted in Mumbai and Kolkata in the year 2019-2020.  A household was enrolled if it had a 12-14 year old adolescent living in it and both adolescent and adult caregivers agreed to participate in the survey. The data from 944 adolescents out of 15,436 enumerated in Mumbai and 1038 out of 24,284 enumerated in Kolkata and their caregivers were analyzed for awareness and ever use of e-cigarettes.  Result: The awareness of e-cigarettes among 12-14 year olds in Mumbai was 15.5%, almost identical among boys and girls whereas is in Kolkata it was 11.2%. In contrast, among the adolescents' adult caregivers in Mumbai, the awareness was low, 3.9% and in Kolkata, 4.6%. Overall awareness was significantly higher among adolescents than among caregivers, especially among adolescent girls than among female caregivers in both cities. CONCLUSION: The awareness and the use of e-cigarette were very little and the messages from the e-cigarette industry seem to be targeted more towards adolescents than adults.  The ban on an e-cigarette in India has helped in prevented the marketing of ENDS to adolescents.

Stars from the bones-An uncommon presentation of fat embolism syndrome.

Trauma or surgery to the lower limbs can cause fat from the marrow within the leg bones to enter the bloodstream and form an embolus. However, if there is cerebral involvement without any pulmonary or dermatological manifestations at diagnosis, it could delay identifying cerebral fat embolism (CFE).

Implementation of an evidence-based tobacco control intervention for school teachers in India: Evaluating the effects of a capacity-building strategy.

Background: Tobacco-Free Teachers, Tobacco-Free Society (TFT-TFS) is an evidence-based intervention that promotes tobacco use cessation among teachers and tobacco control policies among schools in India. This study tested an implementation model to build Bihar Department of Education (DOE) capacity to support and deliver TFT-TFS within schools, leveraging DOE training infrastructure. Method: We used a training-of-trainers (TOT) "cascade" implementation strategy to embed the TFT-TFS program into the Bihar DOE infrastructure. We trained 46 Cluster Coordinators to train and support Headmasters to implement TFT-TFS in their schools over one academic year. We selected three school districts, representing approximately 46 clusters and 219 schools. We used the RE-AIM framework to assess program adoption (Headmaster participation in at least one of six TFT-TFS trainings), implementation (of four core program components), and reach (teachers' participation in three or more group discussions). Using a non-inferiority design, we hypothesized that program adoption, implementation, and reach would not be inferior to the high standards demonstrated when TFT-TFS was originally tested in the Bihar School Teachers Study. We used self-reported checklists to measure outcomes and SPSS Version 25 to analyze data. Results: For adoption, 94% of Headmasters attended the first training, although participation declined by the sixth training. Among the 112 schools out of 219 with complete Headmaster checklist data, all met our minimum criteria for implementing TFT-TFS. Over 99% of schools posted a school tobacco control policy and distributed quit booklets. However, only 69% of schools met our criteria for program reach. Conclusions: This study outlines the processes for taking a tobacco control intervention to scale and implementing it through the Bihar DOE infrastructure. These findings provide a foundation for other Indian states and low- and middle-income countries to implement tobacco control and other health programs for schoolteachers. Trial registration: NCT05346991. Plain Language Summary: Each year in India, more than 1.2 million people die from tobacco-related causes, and India has the world's highest oral cancer burden. The world needs more evidence on how to bring cost-effective tobacco control interventions to scale, especially in low- and middle-income countries (LMICs). To address this gap, from 2017 to 2021, we examined the process of scaling up Tobacco-Free Teachers, Tobacco-Free Society (TFT-TFS), an evidence-based intervention promoting tobacco use cessation among teachers and tobacco control policies in schools. Our study tested an implementation model aimed at building the Bihar State Department of Education (DOE) capacity to support and deliver TFT-TFS. We used a training-of-trainers model to embed TFT-TFS into Bihar DOE infrastructure, training 46 Cluster Coordinators to in turn train and support Headmasters to implement TFT-TFS over one academic year. We hypothesized that program adoption, implementation, and reach would not be inferior to the high standards demonstrated when we originally tested TFT-TFS through the Bihar School Teachers Study (2013-2017). For adoption, 94% of Headmasters attended the first training, although participation declined by the sixth training. Of 112 schools (out of 219 with complete Headmaster checklist data), all met our minimum criteria for implementing TFT-TFS. Over 99% of schools posted a school tobacco control policy and distributed quit booklets. However, only 69% of schools met our criteria for program reach. Study findings offer other Indian states and LMICs lessons to implement tobacco control and other health programs for schoolteachers within educational systems.

The Cultural Context of Plagiarism and Research Misconduct in the Asian Region.

Plagiarism is one of the most frequent forms of research misconduct in South and East Asian countries. This narrative review examines the factors contributing to research misconduct, emphasizing plagiarism, particularly in South, East and Southeast Asian countries. We conducted a PubMed and Scopus search using the terms plagiarism, Asia, South Asia, East Asia, Southeast Asia, research misconduct and retractions in January of 2022. Articles with missing abstracts, incomplete information about plagiarism, publication dates before 2010, and those unrelated to South, East, and Southeast Asian countries were excluded. The retraction watch database was searched for articles retracted between 9th January 2020 to 9th January 2022. A total of 159 articles were identified, of which 21 were included in the study using the database search criteria mentioned above. The review of articles identified a lack of training in scientific writing and research ethics, publication pressure, permissive attitudes, and inadequate regulatory measures as the primary reasons behind research misconduct in scientific publications. Plagiarism remains a common cause of unethical publications and retractions in regions of Asia (namely South, East and Southeast). Researchers lack training in scientific writing, and substantial gaps exist in understanding various forms of plagiarism, which heavily contribute to the problem. There is an urgent need to foster high research ethics standards and adhere to journal policies. Providing appropriate training in scientific writing among researchers may help improve the knowledge of different types of plagiarism and promote the use of antiplagiarism software, leading to a substantial reduction in the problem.

A Case of Pembrolizumab-Induced Diabetic Ketoacidosis and Hyperthyroidism in a Patient With Recurrent Esophageal Adenocarcinoma.

Immune checkpoint inhibitors (ICI) such as program cell death protein 1 (PD-1) inhibitors are widely used for the treatment of patients with recurrent, locally advanced or metastatic, gastric or gastroesophageal (GE) junction adenocarcinoma. Immune-related adverse events (irAE) such as endocrinopathies have been reported after patients received ICI. We report a case of pembrolizumab-induced hyperthyroidism and type 1 diabetes mellitus (DM1) presenting with diabetic ketoacidosis (DKA). A 53-year-old African American male with no history of diabetes or hyperthyroidism was treated with two cycles of pembrolizumab for recurrent GE junction adenocarcinoma after which he was admitted with hyperthyroidism (thyroid stimulating hormone [TSH] 0.070mIU/L, free thyroxine 1.85mIU/L) and DKA (pH 7.06, glucose 583 mg/dL, beta-hydroxybutyrate 8.63 mmol/L, anion gap 27 meq/L). The patient was treated with intravenous insulin and aggressively hydrated. Given the lack of other precipitating factors for the two endocrinopathies, it was determined that the most likely etiology was recent treatment with pembrolizumab (a PD-1 inhibitor). In our case, pembrolizumab monotherapy developed two irAE (hyperthyroidism and DKA), which is unique as most combined immunotherapy regimens are associated with the development of multiple endocrinopathies. Our case emphasizes the importance of baseline monitoring of thyroid function and blood glucose prior to the start of ICI to monitor and evaluate patients with immune-related adverse events, including endocrinopathies.

Common assumptions in tobacco control that may not hold true for South-East Asia.

Tobacco is a threat to public health in South-East Asia and its control should be a priority. However, many common assumptions about tobacco control may not hold true for the region and can misdirect policy. The substantial health risks associated with smokeless tobacco have been largely misunderstood and neglected. The syndemic association between tuberculosis and tobacco has also been overlooked. Similarly, less attention has been paid to address second-hand smoke exposure of pregnant women to indoor smoking (caused predominantly by men). On the other hand, our poor understanding of the diverse tobacco supply chain has been blocking progress in tobacco control. Finally, the rising popularity of electronic cigarettes has thrown new challenges; many governments, concerned for its youth, have banned such products. We argue for a nuanced approach to tobacco control in South-East Asia. We also encourage a wider debate in public health, where other established assumptions may be hampering progress.

Family functioning within the context of families with adolescent children in urban India.

Research on family functioning within given cultural contexts is needed. This study aims to describe salient dimensions of family functioning in two urban contexts in India and to examine differences in family functioning by sociodemographic groups. We measured differences in family functioning using cross-sectional survey questionnaire data collected from 13 to 15-year-old adolescents and one of their parents/primary caregivers in Mumbai (n = 843) and Kolkata (n = 913) during 2019-2020. We drew a multi-stage sample representative of neighborhoods and households in both cities. We assessed a multi-dimensional family functioning latent factor that included parent-reported measures (parent-adolescent communication, family cohesion, and parent monitoring of peers) and adolescent-reported measures (parent support, family cohesion, and parent supervision). Our results support an overall measure of family functioning manifested by multiple dimensions for parent- and adolescent-reported data. Families with male adolescents had worse adolescent-reported family functioning in Mumbai and parent-reported family functioning in Kolkata. Higher socioeconomic status was associated with better parent-reported family functioning in both cities and better adolescent-reported family functioning in Kolkata. Muslim religious identification in Kolkata and the Hindi native language in both cities were associated with better adolescent-reported family functioning. Our findings indicate heterogeneity in family functioning across demographic and social-cultural groups within the two urban contexts of India. This study may inform the development of culturally congruent prevention interventions for families with adolescents in India.
