Effectiveness of Adjunctive High-Dose Infliximab Therapy to Improve Disability-Free Survival Among Patients With Severe Central Nervous System Tuberculosis: A Matched Retrospective Cohort Study.

BACKGROUND: Few treatment options exist for patients with severe central nervous system (CNS) tuberculosis (TB) worsening due to inflammatory lesions, despite optimal antitubercular therapy (ATT) and steroids. Data regarding the efficacy and safety of infliximab in these patients are sparse. METHODS: We performed a matched retrospective cohort study based on Medical Research Council (MRC) grading system and modified Rankin Scale (mRS) scores comparing 2 groups of adults with CNS TB. Cohort A received at least 1 dose of infliximab after optimal ATT and steroids between March 2019 and July 2022. Cohort B received only ATT and steroids. Disability-free survival (mRS score ≤2) at 6 months was the primary outcome. RESULTS: Baseline MRC grades and mRS scores were similar between the cohorts. Median duration before initiation of infliximab therapy from start of ATT and steroids was 6 (IQR: 3.7-13) months and for neurological deficits was 4 (IQR: 2-6.2) months. Indications for infliximab were symptomatic tuberculomas (20/30; 66.7%), spinal cord involvement with paraparesis (8/30; 26.7%), and optochiasmatic arachnoiditis (3/30; 10%), worsening despite adequate ATT and steroids. Severe disability (5/30 [16.7%] and 21/60 [35%]) and all-cause mortality (2/30 [6.7%] and 13/60 [21.7%]) at 6 months were lower in cohort A versus cohort B, respectively. In the combined study population, only exposure to infliximab was positively associated (aRR: 6.2; 95% CI: 2.18-17.83; P = .001) with disability-free survival at 6 months. There were no clear infliximab-related side effects noted. CONCLUSIONS: Infliximab may be an effective and safe adjunctive strategy among severely disabled patients with CNS TB not improving despite optimal ATT and steroids. Adequately powered phase 3 clinical trials are required to confirm these early findings.

High susceptibility to varicella among urban and rural pregnant women in South India: a brief report.

Varicella infection during pregnancy has serious and/or difficult implications and in some cases lethal outcome. Though epidemiological studies in developing countries reveal that a significant proportion of patients may remain susceptible during pregnancy, such an estimate of susceptible women is not known in India. We designed this study to study the prevalence and factors associated with susceptibility to varicella among rural and urban pregnant women in South India. We prospectively recruited 430 pregnant women and analysed their serum varicella IgG antibodies as surrogates for protection. We estimated seroprevalence, the validity of self-reported history of chickenpox and factors associated with varicella susceptibility. We found 23 (95% CI 19.1-27.3) of women were susceptible. Nearly a quarter (22.2%) of the susceptible women had a history of exposure to chickenpox anytime in the past or during the current pregnancy. Self-reported history of varicella had a positive predictive value of 82.4%. Negative history of chickenpox (adjusted prevalence ratio (PR) 1.85, 95% CI 1.15-3.0) and receiving antenatal care from a rural secondary hospital (adjusted PR 4.08, 95% CI 2.1-7.65) were significantly associated with susceptibility. We conclude that high varicella susceptibility rates during pregnancy were noted and self-reported history of varicella may not be a reliable surrogate for protection.

High seroprevalence of COVID-19 infection in a large slum in South India; what does it tell us about managing a pandemic and beyond?

People living in urban slums or informal settlements are among the most vulnerable communities, highly susceptible to coronavirus disease 2019 (COVID-19) infection and vulnerable to the consequences of the measures taken to control the spread of the virus. Fear and stigma related to infection, mistrust between officials and the population, the often-asymptomatic nature of the disease is likely to lead to under-reporting. We conducted a cross-sectional study to determine the seroprevalence of COVID-19 infection in a large slum in South India 3 months after the index case and recruited 499 adults (age >18 years). The majority (74.3%) were females and about one-third of the population reported comorbidities. The overall seroprevalence of IgG antibody for COVID-19 was 57.9% (95% CI 53.4-62.3). Age, education, occupation and the presence of reported comorbidities were not associated with seroprevalence (P-value >0.05). Case-to-undetected-infections ratio was 1:195 and infection fatality rate was calculated as 2.94 per 10 000 infections. We estimated seroprevalence of COVID-19 was very high in our study population. The focus in this slum should shift from infection prevention to managing the indirect consequences of the pandemic. We recommend seroprevalence studies in such settings before vaccination to identify the vulnerability of COVID-19 infection to optimise the use of insufficient resources. It is a wake-up call to societies and nations, to dedicate paramount attention to slums into recovery and beyond - to build, restore and maintain health equity for the 'Health and wellbeing of all'.

Benefit or Harm? A Study on Impact of Collusion on the Quality of Life among Palliative Care Patients.

BACKGROUND: In India, roughly one-half of patients undergoing cancer treatment are unaware of their diagnosis or treatment. The intention of this study is to determine the prevalence of collusion and its influence on quality of life (QOL) among patients in palliative care settings. METHODOLOGY: A cross-sectional study was conducted among 100 palliative care patients to assess the extent of knowledge about their diagnosis and prognosis. The caretakers and the treating doctors were interviewed using a semi-structured questionnaire to assess if diagnosis was revealed to a patient. QOL of the patients was assessed using the European Organisation for Research and Treatment of Cancer QOL Questionnaire-C30 questionnaire. RESULTS: The prevalence of collusion was 37%, i.e., in more than one-third of the palliative care patients; caregivers restrained doctors from disclosing the diagnosis. The prevalence of collusion was less among patients with higher educational qualification (P = 0.027) and professionals (P = 0.025). Collusion was not associated with gender, type of family, place of residence, and socioeconomic status (SES). In multivariate regression, collusion (odds ratio = 10.53) was independently associated with poor QOL when adjusted for age, gender, place of residence, religion, educational status, family type, and SES. CONCLUSION: Collusion is fairly prevalent and it worsens the QOL among cancer patients. Since the main driver for collusion is the strong desire among caregivers to protect the physical and psychological well-being, the findings of the study could motivate the caregiver for a more open and honest communication.

Perception of unintentional childhood injuries among mothers in rural South India.

Parental perception of safe and risk-free environment is critical in the prevention of unintentional childhood injury. In this cross-sectional study, hundred mothers from 13 clusters were interviewed to assess the perception of mothers regarding the risks and hazards leading to unintentional childhood injuries from March to April 2013. A tool developed by Glik et al. was used. Mothers' perception of likelihood of injury from hazards such as household door and drawers, small toys, plastic bags, and cribs was poor. Mothers had a poor perception of injury by entrapment in refrigerators, choking, and strangulation by a rope. Age, education, and literacy (P < 0.05) were found to be significant predictors of perception of risk and hazard. Very few mothers (9%) believed injuries can be completely prevented and illiteracy (P < 0.05) was associated with poor perception on prevention. Health education should focus on improving maternal perception which may bring positive impact on prevention.

Comparative evaluation of intensified short course regimen and standard regimen for adults TB meningitis: a protocol for an open label, multi-center, parallel arms, randomized controlled superiority trial (INSHORT trial).

BACKGROUND: Despite several incremental improvements in the management of tuberculous meningitis (TBM), the mortality rates remain high. In spite of national and international guidelines, variation in the choice, dose, and duration of drugs exist between countries and clinicians. We propose to evaluate a shorter and more effective regimen containing agents with augmented intracerebral drug exposure and anti-inflammatory approaches to improve disability-free survival among patients with TBM. Our strategy incorporates the various developments in the field of TBM over the last two decades and only few trials have evaluated a composite of these strategies in the overall outcomes of TBM. METHODS: An open label, parallel arms, randomized controlled superiority trial will be conducted among 372 participants across 6 sites in India. Eligible participants will be randomly allocated in 1:1:1 ratio into one of the three arms. The intervention arm consists of 2 months of high-dose rifampicin (25 mg/kg), moxifloxacin (400 mg), pyrazinamide, isoniazid, aspirin (150 mg), and steroids followed by rifampicin, isoniazid, and pyrazinamide for 4 months. The second intervention arm includes all the drugs as per the first arm except aspirin and the patients in the control arm will receive treatment according to the National TB Elimination Program guidelines. All participants will be followed up for 1 year after the treatment.  DISCUSSION: Current WHO regimens have agents with poor central nervous system drug exposure and is too long. It does not reflect the accumulating evidence in the field. We propose a comprehensive clinical trial incorporating the emerging evidence accrued over the last two decades to shorten the duration and improve the treatment outcomes. This multi-centric trial may generate crucial evidence with policy and practice implications in the treatment of TBM. TRIAL REGISTRATION: Clinical Trial Registry India CTRI/2023/05/053314.

Immunogenicity of SARS-CoV-2 vaccines BBV152 (COVAXIN®) and ChAdOx1 nCoV-19 (COVISHIELD™) in seronegative and seropositive individuals in India: a multicentre, nonrandomised observational study.

Background: There are limited global data on head-to-head comparisons of vaccine platforms assessing both humoral and cellular immune responses, stratified by pre-vaccination serostatus. The COVID-19 vaccination drive for the Indian population in the age group 18-45 years began in April 2021 when seropositivity rates in the general population were rising due to the delta wave of COVID-19 pandemic during April-May 2021. Methods: Between June 30, 2021, and Jan 28, 2022, we enrolled 691 participants in the age group 18-45 years across four clinical sites in India. In this non-randomised and laboratory blinded study, participants received either two doses of Covaxin® (4 weeks apart) or two doses of Covishield™ (12 weeks apart) as per the national vaccination policy. The primary outcome was the seroconversion rate and the geometric mean titre (GMT) of antibodies against the SARS-CoV-2 spike and nucleocapsid proteins post two doses. The secondary outcome was the frequency of cellular immune responses pre- and post-vaccination. Findings: When compared to pre-vaccination baseline, both vaccines elicited statistically significant seroconversion and binding antibody levels in both seronegative and seropositive individuals. In the per-protocol cohort, Covishield™ elicited higher antibody responses than Covaxin® as measured by seroconversion rate (98.3% vs 74.4%, p < 0.0001 in seronegative individuals; 91.7% vs 66.9%, p < 0.0001 in seropositive individuals) as well as by anti-spike antibody levels against the ancestral strain (GMT 1272.1 vs 75.4 binding antibody units/ml [BAU/ml], p < 0.0001 in seronegative individuals; 2089.07 vs 585.7 BAU/ml, p < 0.0001 in seropositive individuals). As participants at all clinical sites were not recruited at the same time, site-specific immunogenicity was impacted by the timing of vaccination relative to the delta and omicron waves. Surrogate neutralising antibody responses against variants-of-concern including delta and omicron was higher in Covishield™ recipients than in Covaxin® recipients; and in seropositive than in seronegative individuals after both vaccination and asymptomatic infection (omicron variant). T cell responses are reported from only one of the four site cohorts where the vaccination schedule preceded the omicron wave. In seronegative individuals, Covishield™ elicited both CD4+ and CD8+ spike-specific cytokine-producing T cells whereas Covaxin® elicited mainly CD4+ spike-specific T cells. Neither vaccine showed significant post-vaccination expansion of spike-specific T cells in seropositive individuals. Interpretation: Covishield™ elicited immune responses of higher magnitude and breadth than Covaxin® in both seronegative individuals and seropositive individuals, across cohorts representing the pre-vaccination immune history of most of the vaccinated Indian population.

Effectiveness and safety of Levofloxacin containing regimen in the treatment of Isoniazid mono-resistant pulmonary Tuberculosis: a systematic review.

Background: We aimed to determine the effectiveness and safety of the Levofloxacin-containing regimen that the World Health Organization is currently recommending for the treatment of Isoniazid mono-resistant pulmonary Tuberculosis. Methods: Our eligible criteria for the studies to be included were; randomized controlled trials or cohort studies that focused on adults with Isoniazid mono-resistant tuberculosis (HrTB) and treated with a Levofloxacin-containing regimen along with first-line anti-tubercular drugs; they should have had a control group treated with first-line without Levofloxacin; should have reported treatment success rate, mortality, recurrence, progression to multidrug-resistant Tuberculosis. We performed the search in MEDLINE, EMBASE, Epistemonikos, Google Scholar, and Clinical trials registry. Two authors independently screened the titles/abstracts and full texts that were retained after the initial screening, and a third author resolved disagreements. Results: Our search found 4,813 records after excluding duplicates. We excluded 4,768 records after screening the titles and abstracts, retaining 44 records. Subsequently, 36 articles were excluded after the full-text screening, and eight appeared to have partially fulfilled the inclusion criteria. We contacted the respective authors, and none responded positively. Hence, no articles were included in the meta-analysis. Conclusion: We found no "quality" evidence currently on the effectiveness and safety of Levofloxacin in treating HrTB.

Leukotriene A4 hydrolase (LTA4H rs17525495) gene polymorphisms and paradoxical reactions in extrapulmonary tuberculosis.

Paradoxical reactions (PRs) are poorly studied complex immunological phenomena, among patients with tuberculosis (TB). When PRs involves critical structures like the central nervous system (CNS), immunomodulatory therapy is often required. Predictors for PRs in TB to pre-empt appropriate treatment strategies in high-risk groups are lacking. TT genotype of Leukotriene A4 hydrolase (LTA4H) promoter region rs17525495 polymorphisms are associated with exaggerated immune responses in Tuberculous meningitis (TBM), the most severe form of extrapulmonary tuberculosis (EPTB). The association of these polymorphisms with PRs is not known. We evaluated this plausibility among 113 patients with EPTB, at high risk of PRs. Majority [81 (71.7%)] had disseminated tuberculosis with prominent CNS [54 (47.8%)] and lymph node involvement [47 (41.6%)]. Human immunodeficiency Virus (HIV) co-infection was seen among 23 (20.3%) patients. PRs were noted in 38.9% patients, at a median duration of 3 months (IQR 2-4). LTA4H rs17525495 single nucleotide polymorphism (SNP) analysis showed 52 (46%) patients had CC, 43 (38.1%) had CT and 18 (15.9%) had TT genotypes. There was no statistically significant difference in occurrence [CC 38.5% vs CT 39.5% vs TT 38.7%] and time of onset [median (IQR)] of PRs across the genotypes [CC 3 (1-4.7), CT 3 (2-5), TT 2 (2-3)]. PRs was shown to be significantly linked with HIV co-infection (RR 0.6, 95% CI 0.29-1.28), culture positivity (RR 0.5, 95% CI 0.28-1.14), TB Lymphadenitis (RR 0.7, 95% CI 0.44-1.19) and CNS involvement RR 2.1, 95% CI 1.27-3.49) in the univariate analysis (p < 0.2). On multivariate analysis, CNS involvement alone was associated with PRs (aRR 3.8 (1.38-10.92); p < 0.01). PRs were associated with CNS involvement but not with LTA4H rs17525495 polymorphisms.

Are hospitals epicentres of COVID19 transmission? Findings of serial serosurveys among healthcare workers from a tertiary hospital in South India.

We conducted a serial cross-sectional study and used blood bank donors serosurvey and the ICMR serosurvey reports for comparison. Seroprevalence was 0% among HCWs (n-211) and blood bank donors (n-210) during the first phase while ICMR serosurvey reported 0.5% among general population in the district at the same time. In phase 2, we estimated a seroprevalence of 9.2% as compared to 18.8% among general population. Seroprevalence among HCWs was comparable to that of the general population during both phases. We postulate that good infection control policies and practice can provide safe working environment without additional risk to HCWs.

Is self-reported adherence a valid measure of glycaemic control among people living with diabetes in rural India? A cross-sectional analysis.

BACKGROUND: Visual analogue scale (VAS) is one of the simplest to measure medication adherence. It has neither been widely used for Non communicable diseases (NCD) nor validated for in the Indian setting. We examined the validity of self-reported medication adherence measures in relation to HbA1C in a rural population with diabetes mellitus (DM). METHODS: Participants with DM was administered VAS, Diabetes Self-Management Questionnaire (DMSQ) and assessed for missed pills. Descriptive statistics and logistic regression analysis were done. RESULTS: We recruited 1347 participants and 84% of them reported being 100% adherent as per VAS and 83.8% stated that they did not miss any pills. However, 58.2% of participants who reported having 100% adherence had poor glycaemic control, as did 58.1% of those who did not miss any pills. None of the diabetic self-care measures was significantly associated with glycaemic control. CONCLUSION: We found a lack of association between self-reported adherence measures and glycaemic control in participants with DM suggesting that self-reported adherence scales may not be valid in this population.

Seroprevalence of SARS CoV-2 among children after the second surge (June 2021) in a rural district of South India: Findings and lessons from a population-based survey.

Objective: To determine the seroprevalence of SARS COV 2 among children in the Bangalore Rural district. Methods: We conducted a cross-sectional study after the second surge of COVID-19 from 14 June to 13 July 2021 and recruited 412 children through house to house visits from four villages in a rural district. We administered a questionnaire to collect demographics and details of COVID-19 infection and used the ABCHEK Antibody Card test (NuLifecare,India) which is an ICMR approved test for detecting antibodies (IgG & IgM) by immunochromatography using the finger prick method. We used Statistical Package for the Social Sciences version 20.0 for analysis. Results: Our participants had an age group ranging from 11 months to 18 years. There was an almost equal distribution of boys (48.3%) and girls (51.7%). We estimated seroprevalence of 45.9% (95% CI: 41-50.8) among children. Seroprevalence was significantly associated with a history of symptoms suggestive of COVID-19 in the past, the seropositive status of the parents, and any other family members being tested positive. Age and gender of the child, education and occupation of the parents were not associated with the seropositivity status of the child. Conclusion: Seroprevalence of COVID-19 among children corresponds to adult seroprevalence during the same time interval. This knowledge can be of practical application where adult prevalence is documented. Unvaccinated children in low-resource settings need special attention with respect to monitoring for new mutations as well as managing endemic needs.

Seroprevalence of COVID-19 infection among vaccine naïve population after the second surge (June 2020) in a rural district of South India: A community-based cross-sectional study.

OBJECTIVE: To determine the seroprevalence of the SARS Cov 2 infection among vaccine naive population in a rural district of South India post-second surge. METHODOLOGY: We conducted a cross-sectional study in the five villages of a randomly chosen sub-district in the Bangalore rural district. We did house to house surveys and recruited 831 vaccine naive adults in July 2021. We tested samples for the presence of antibodies (including IgG & IgM) to SARS CoV-2 using the Roche Elecsys SARS-CoV-2 -S assay that quantifies antibodies against the receptor-binding domain (RBD) of the spike (S) protein. RESULTS: We estimated an overall prevalence of 62.7% (95% CI: 59.3-66.0) and an age-and gender-adjusted seroprevalence of 44.9% (95% CI: 42.5-47.4). When adjusted for test performance, the seroprevalence was 74.64% (95% CI: 70.66-78.47). The case-to-undetected-infected ratio (CIR) was 1: 8.65 (95% CI 1:8.1-1:9.1), and the Infection Fatality Rate (IFR) was 16.27 per 100,00 infections as of 13 July 2021. A history of at least one symptom suggestive of COVID-19 or a positive COVID-19 test of self or a family member in the past were significantly associated with seropositivity. CONCLUSION: We report a high seroprevalence of COVID-19 infection despite the advantages of low population density and well-ventilated landscapes in rural areas. CIR and IFR were higher than the previous serosurvey conducted in the same population during the first surge. The thought of achieving herd immunity comes with relief. However, it's vital to put efforts into building population health and rural health infrastructure to avert future health catastrophes.

COVID-19 symptoms are reduced by targeted hydration of the nose, larynx and trachea.

Dehydration of the upper airways increases risks of respiratory diseases from COVID-19 to asthma and COPD. We find in human volunteer studies involving 464 human subjects in Germany, the US, and India that respiratory droplet generation increases by up to 4 orders of magnitude in dehydration-associated states of advanced age (n = 357), elevated BMI-age (n = 148), strenuous exercise (n = 20) and SARS-CoV-2 infection (n = 87), and falls with hydration of the nose, larynx and trachea by calcium-rich hypertonic salts. We also find in a protocol of exercise-induced airway dehydration that hydration of the airways by calcium-rich salts increases oxygenation relative to a non-treatment control (P < 0.05). In a random control study of COVID-19 positive subjects (n = 40), thrice-a-day delivery of the calcium-rich hypertonic salts (active) suppressed respiratory droplet generation by 51% ± 11% and increased oxygen saturation over three days of treatment by 48.08% ± 9.61% (P < 0.001), while no changes were observed in the nasal-saline control group. Self-reported symptoms significantly declined in the active group and did not decline in the control group. Hydration of the upper airways appears promising as a non-drug approach for reducing risks of respiratory diseases such as COVID-19.

Seroprevalence of COVID-19 infection in a rural district of South India: A population-based seroepidemiological study.

OBJECTIVES: We aimed to estimate the seroprevalence of COVID-19 in a rural district of South India, six months after the index case. METHODOLOGY: We conducted a cross-sectional study of 509 adults aged more than 18 years. From all the four subdistricts, two grampanchayats (administrative cluster of 5-8 villages) were randomly selected followed by one village through convenience. The participants were invited for the study to the community-based study kiosk set up in all the eight villages through village health committees. We collected socio-demographic characteristics and symptoms using a mobile application-based questionnaire, and we tested samples for the presence of IgG antibodies for SARS CoV-2 using an electro chemiluminescent immunoassay. We calculated age-gender adjusted and test performance adjusted seroprevalence. RESULTS: The age-and gender-adjusted seroprevalence was 8.5% (95% CI 6.9%- 10.8%). The unadjusted seroprevalence among participants with hypertension and diabetes was 16.3% (95% CI:9.2-25.8) and 10.7% (95% CI: 5.5-18.3) respectively. When we adjusted for the test performance, the seroprevalence was 6.1% (95% CI 4.02-8.17). The study estimated 7 (95% CI 1:4.5-1:9) undetected infected individuals for every RT-PCR confirmed case. Infection Fatality Rate (IFR) was calculated as 12.38 per 10000 infections as on 22 October 2020. History of self-reported symptoms and education were significantly associated with positive status (p < 0.05). CONCLUSION: A significant proportion of the rural population in a district of south India remains susceptible to COVID-19. A higher proportion of susceptible, relatively higher IFR and a poor tertiary healthcare network stress the importance of sustaining the public health measures and promoting early access to the vaccine are crucial to preserving the health of this population. Low population density, good housing, adequate ventilation, limited urbanisation combined with public, private and local health leadership are critical components of curbing future respiratory pandemics.

Prevalence, risk factors and quality of life of Lower Urinary Tract Symptoms (LUTS) among men attending Primary Care slum clinics in Bangalore: A cross-sectional study.

BACKGROUND: Men, more than 50 years of age, have a higher incidence of lower urinary tract symptoms (LUTS), and this increases with the advancing age. The prevalence of LUTS varies in different geographical areas across the world, and studies have reported that LUTS in men may significantly affect the quality of life (QoL) and influence their health-seeking behavior. Early detection of LUTS is essential as it is related to several complications. This study aimed to estimate the prevalence of LUTS and factors associated with LUTS and health-seeking behavior. METHODS: We interviewed 201 men (>50 years) attending two urban primary care clinics in Bangalore using the IPSS questionnaire and calculated the prevalence of LUTS. Factors associated with LUTS and health seeking-behavior were tested using the Chi-square test. A P-value less than 0.05 was considered as significant. RESULTS: The prevalence of LUTS was 85%. LUTS was significantly associated with those having diabetes and those consuming more than two cups of tea per day. The most common symptom was nocturia (85.4%) and a weak stream (35.0%). Moderate and severe LUTS were significantly associated with poor QoL score (P < 0.0001). Only 9.3% of the men sought medical help in spite of their symptoms, and the most common reason for seeking health care was the disturbance they had due to the urinary symptoms (81.3%). CONCLUSIONS: Family physicians should be aware that a significant proportion of the men in the age group of 50 years suffer from LUTS, and eliciting the same is essential during the process of consultation.

A community-based cross-sectional study on knowledge, attitude, and perceptions about asthma among healthy adults in rural South India.

BACKGROUND: Evidence suggests that proper knowledge and perceptions about asthma result in a positive correlation with compliance with medications and regular medical follow-up. Assessing the level of knowledge, attitude, and perception (KAP) in the community is essential for planning public health interventions. There is a lacuna on community-based KAP study on asthma in rural India, as most of the existing evidence is from hospital-based studies in an urban setting. METHODS: We interviewed 280 healthy adults from 14 villages in South India using the Chicago community asthma survey-32 (CCAS-32) questionnaire. We noted the frequency distribution of responses to the questions and scored KAP on symptoms, triggers, and treatment, and performed bivariate and multivariate analyses. RESULTS: The mean age was 37.7 years ranging from 18 to 62 years. Almost half of them (47%) had primary or middle school education. 40.7% and 57.9% believed severe headache and tightness of chest were symptoms of asthma, respectively. Similarly, 38.2% and 48.4% thought asthma was a hereditary and contagious disease, respectively, whereas 41.8% of perceived asthma medications could be addictive. Having witnessed "patients with asthma" was associated with KAP on symptoms and triggers while younger age and having a relative with asthma were associated with KAP on treatment independently. Participants who had relatives with asthma were three times [(OR 3.04; 95% (1.5-6.1)] more likely to have good KAP compared to their counterparts. CONCLUSION: Asthma knowledge and perceptions are sparse in rural India. Adequate investments in public awareness are the need of the hour.

Gut Microbial Profile Is Associated With Residential Settings and Not Nutritional Status in Adults in Karnataka, India.

Undernutrition is a leading contributor to disease and disability in people of all ages. Several studies have reported significant association between nutritional status and gut microbiome composition but other factors such as demographic settings may also influence the adult microbiome. The relationship between undernourishment and gut microbiome in adults has not been described to date. In this study, we compared the gut microbiome in fecal samples of 48 individuals, from two demographic settings (rural and urban slum) in Karnataka, India using 16S rRNA sequencing. Nutritional status was assessed based on BMI, with a BMI of < 18.5 kg/m2 classified as undernourished, and a BMI in the range 18.5-25 kg/m2 as nourished. We analyzed 25 individuals from rural settings (12 undernourished and 13 nourished) and 23 individuals from urban slum settings (11 undernourished and 12 nourished). We found no significant difference in overall gut microbial diversity (Shannon and Unweighted UniFrac) between undernourished and nourished individuals in either geographical settings, however, microbial taxa at the phylum level (i.e., Firmicutes and Proteobacteria) and beta diversity (unweighted UniFrac) differed significantly between the rural and urban slum settings. By predicting microbial function from 16S data profiling we found significant differences in metabolic pathways present in the gut microbiota from people residing in different settings; specifically, those related to carbohydrate and lipid metabolism. The weighted sum of the KEGG Orthologs associated with carbohydrate metabolism (Spearman's correlation coefficient, ρ = -0.707, p < 0.001), lipid metabolism (Spearman's correlation coefficient, ρ = -0.330, p < 0.022) and biosynthesis of secondary metabolites (Spearman's correlation coefficient, ρ = -0.507, p < 0.001) were decreased in the urban slum group compared to the rural group. In conclusion, we report that the geographical location of residence is associated with differences in gut microbiome composition in adults. We found no significant differences in microbiome composition between nourished and undernourished adults from urban slum or rural settings in India.

Extent of awareness and attitudes on plagiarism among post-graduate resident doctors and junior medical faculty in India: a cross-sectional, multicentric study.

OBJECTIVES: Though dissertation is mandatory for postgraduates (PG), it is unknown if adequate knowledge on plagiarism exists at that level. Thus, we intended to study the knowledge and attitude towards plagiarism among junior doctors in India. DESIGN: Cross-sectional study SETTING: PG medical residents and Junior faculty from various teaching institutions across south India. PARTICIPANTS: A total of N=786 doctors filled the questionnaires of which approximately 42.7% were from government medical colleges (GMCs) and the rest from private institutions. METHODS: Participants were given a pretested semistructured questionnaire which contained: (1) demographic details; (2) a quiz developed by Indiana University, USA to assess knowledge and (3) Attitudes towards Plagiarism Questionnaire (ATPQ). OUTCOME MEASURES: The Primary outcome measure was knowledge about plagiarism. The secondary outcome measure was ATPQ scores. RESULTS: A total of N=786 resident doctors and junior faculty from across 11 institutions participated in this study. Of this, 42.7% were from GMCs and 60.6% were women. The mean (SD) knowledge score was 4.43 (1.99) out of 10. The factors (adjusted OR; 95% CI; p value) that emerged as significant predictors of knowledge were number of years in profession (-0.181; -0.299 to -0.062; 0.003), no previous publication (0.298; 0.099 to 0.498; 0.003) and working in a GMC (0.400; 0.106 to 0.694; 0.008). The overall mean (SD) scores of the three attitude components were: Permissive attitudes-37.33 (5.33), critical attitudes -20.32 (4.82) and subjective norms-31.05 (4.58), all of which corresponded to the moderate category. CONCLUSION: Participants lacked adequate knowledge on how to avoid plagiarism suggesting a need for a revamp in medical education curriculum in India by incorporating research and publication ethics.
