RESUMO
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.

BACKGROUND: Different combinations of lifestyle interventions have been studied with varying results on hypertension control. Hence, this review was done to compare multiple combined lifestyle intervention in reducing blood pressure (BP) among patients with prehypertension or hypertension. METHODS: We conducted systematic search in the following databases: MEDLINE, PubMed Central, CENTRAL, ScienceDirect, Google Scholar from 1964 until November 2020. Estimates of comparative intervention effect from network meta-analyses (random-effects model) were represented as mean difference (MD) with 95% confidence interval. RESULTS: In total, 14 studies with 2451 participants were included. Almost all the studies had high risk of bias. Healthy diet (HD) and physical activity (PA) combination showed highest mean reduction in systolic BP (-9.88 mmHg) and diastolic BP (-6.28 mmHg) followed by HD + PA + smoking cessation + alcohol restriction combination (systolic BP = -6.58 mmHg, diastolic BP = -4.09 mmHg) compared with usual care. HD and PA combination had the highest probability of being the best intervention (82.8% for SBP and 81.7% for DBP). CONCLUSION: We found that HD and PA are the most important combination of lifestyle modifications for prehypertensive and hypertensive patients. Hence, a coordinated approach is required from the clinicians by integrating beneficial effect of these modifications through education, counselling and support.

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

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.

AIMS: The impact of behavioural risk factors on the metabolic syndrome has not been well understood by the researchers. This information is important to the policymakers for developing effective strategies and implement relevant policies or programs. Hence, we undertook this meta-analysis to estimate the effect of behavioural risk factors on the burden of metabolic syndrome. DATA SYNTHESIS: We conducted a search in the databases, such as PubMed Central, EMBASE, MEDLINE, and Cochrane library, and search engines, such as ScienceDirect and Google Scholar, from inception until March 2021. We used the Newcastle-Ottawa Scale (NOS) to assess the quality of published studies. We carried out a meta-analysis with random-effects model and reported pooled odds ratio (OR) with 95% confidence interval (CI). In total, we analysed 30 studies with 41,090 participants. The majority of the studies had good to satisfactory quality as per NOS. Physical activity had a statistically significant association with the prevalence of metabolic syndrome (pooled OR = 1.57; 95%CI: 1.28 to 1.93, I2 = 91%). However, smoking (pooled OR = 0.96; 95%CI: 0.75 to 1.23, I2 = 90.5%) and alcohol (pooled OR = 1.00; 95%CI: 0.75 to 1.33, I2 = 90.8%) did not reveal a statistically significant association with the burden of metabolic syndrome. CONCLUSION: Physical inactivity was found to be a significant risk factor for metabolic syndrome. Given the evidence, it is important that the clinicians and policymakers are alike to recommend regular physical activity among the patients and general population.

INTRODUCTION: Several studies have explored the effect of anthropometric risk factors on metabolic syndrome. However, no systematic effort has explored the effect of overweight and obesity on the prevalence of metabolic syndrome in India. Thus, we undertook a meta-analysis to estimate the effect of anthropometric risk factors on the prevalence of metabolic syndrome. METHODS: We searched databases PubMed Central, EMBASE, MEDLINE, and Cochrane library and search engines ScienceDirect and Google Scholar, from January 1964 through March 2021. We used the Newcastle-Ottawa scale to assess the quality of published studies, conducted a meta-analysis with a random-effects model, and reported pooled odds ratios (OR) with 95% CIs. RESULTS: We analyzed 26 studies with a total of 37,965 participants. Most studies had good to satisfactory quality on the Newcastle-Ottawa scale. Participants who were overweight (pooled OR, 5.47; 95% CI, 3.70-8.09) or obese (pooled OR, 5.00; 95% CI, 3.61-6.93) had higher odds of having metabolic syndrome than those of normal or low body weight. Sensitivity analysis showed no significant variation in the magnitude or direction of outcome, indicating the lack of influence of a single study on the overall pooled estimate. CONCLUSION: Overweight and obesity are significantly associated with metabolic syndrome. On the basis of evidence, clinicians and policy makers should implement weight reduction strategies among patients and the general population.

OBJECTIVE: We aimed to determine the prevalence and find the risk factors associated with latent tuberculosis infection (LTBI) among the household contacts (HHC) of pulmonary TB patients. METHODS: This cohort study was conducted from 2014 to 2019. Pretested standardised questionnaires and tools were used for data collection. The prevalence of LTBI among HHCs of TB patients was summarised as proportion with 95% confidence interval (CI). Mixed-effects generalised linear modelling function (meglm) in STATA with family Poisson and log link was performed to find the factors associated with LTBI. RESULTS: In total, 1523 HHC of pulmonary TB patients were included in the study. Almost all HHC shared their residence with the index case (IC) for more than a year; 25% shared the same bed with the IC. The prevalence of LTBI among the HHC of TB patients was 52.6% (95% CI: 50.1-55.1%). In an adjusted model, we found that among HHC belonging to the age group of 19-64 years (aIRR = 1.2; 95% CI: 1.1-1.3; p-value: 0.02), to the age group >65 years (aIRR = 1.4, 95% CI: 1.1-1.9, p-value: 0.02) and sharing the same bed with the IC (aIRR = 1.2, 95% CI: 1.1-1.3, p value: 0.04) were independent determinants of LTBI among the HHC. CONCLUSION: One in two household contacts of TB patients have latent tuberculosis infection. This underscores the need of targeted contact screening strategies, effective contact tracing and testing using standardised methods in high TB burden settings.

Background: Cardiovascular diseases (CVDs) account for over three-quarters of all deaths taking place in developing nations. Objective: The present study aims to stratify noncommunicable disease (NCD) patients using the Globorisk chart for predicting their 10-year risk of a major (fatal or nonfatal) CVD event and to estimate the level of agreement between this country-specific chart and the existing World Health Organization (WHO)/International Society of Hypertension (ISH) risk strata. Methods: A record-based cross-sectional analytical study was conducted in 2018 among adults attending the NCD clinic of one rural and one urban primary health center in Puducherry. Laboratory and office risk calculators of the Globorisk chart were used to calculate the risk. Results: The median age (interquartile range (IQR)) of the 760 study participants was 58 (50-65) years. When calculated using the Globorisk prediction chart, 22.1% (n = 168) of the participants had a <10% risk for any CVD event in the next 10 years, whereas the same risk was found in 71.1% (n = 540) by using the WHO/ISH risk chart. There was no agreement found between the two risk charts (k = 0.0174; P-value = 0.26). Conclusion: The Globorisk chart was found to identify more patients as belonging to the higher risk category as compared to WHO/ISH charts.
RESUMO
OBJECTIVES: The objective was to study the effect of serial night shifts on the cognitive, psychomotor, and moral performance of emergency medicine residents of an academic Emergency Medicine Department. METHODS: This prospective case-crossover study compared emergency medicine residents' sleep time, subjective sleepiness, cognitive function, moral judgment, and psychomotor skills after 5 consecutive days versus night shifts using sleep diaries, activity monitors, and multiple performance tests. Paired t-tests and Wilcoxon signed-rank tests were used to analyze data based on normality. Correlation analysis was done using Spearman's correlation test. Subgroup analysis was also performed to find any difference based on gender and year of residency. RESULTS: Twenty-seven emergency medicine residents participated (13 males, 48.1%). The distribution across residency years was as follows: 44.4% in their first year, 25.9% in their second year, and 29.6% in their third year. Following five consecutive night shifts, total sleep duration decreased significantly from 338.1 ± 67.8 to 307.4 ± 71.0 min (p < 0.001), while subjective sleepiness scores increased from 9.6 ± 3.3 to 13.6 ± 4.6. Psychomotor performance and reaction times did not significantly differ between night and day shifts. However, working memory declined, assessed by self-paced three-back test scores (median [IQR] 517.1 [471.9-546.7] vs. 457.6 [334.4-508.8]; p = 0.034) and interference test scores (445.5 ± 59.9 vs. 407.2 ± 56.8; p < 0.001), along with moral judgment (median [IQR] 19 [18-28] vs. 15 [11-21]; p = 0.010) after serial night shifts. No correlations existed between performance measures nor differences based on gender or residency year. CONCLUSIONS: Residents sleep less following night versus day shifts, reporting the highest sleepiness levels after 5 consecutive nights. Despite this, psychomotor performance and reaction times did not significantly differ. However, considerable reductions occurred in moral judgment, working memory, and interference test performance after serial night shifts.
RESUMO
We conducted a pre-post intervention study to determine knowledge, attitude, and practice toward dietary salt intake before, immediately, and 1-month after nurse-led one-on-one counseling. We purposively selected three public health facilities in Agra, India, and enrolled all eligible hypertensive patients aged 18-60 under treatment for ≥6 months. Of the 153 patients at the 1-month follow-up, counseling improved knowledge (4% vs. 42%, p < .001), a greater prioritization of a low salt diet (34% vs. 52%, p < .001), and practice of adding less salt to the dough (48% to 41%, p < .001). The counseling intervention improved knowledge, attitude, and practice toward dietary salt intake.

Background: Wearing a mask is one of the simplest ways to reduce the spread of COVID-19. Studies reported poor mask compliance in Greater Chennai Corporation, India. Hence, we described the knowledge, attitude, and practice regarding mask use among adults (≥18 years) in Greater Chennai Corporation, Tamil Nadu, India. Methods: We conducted a cross-sectional survey among residents of Greater Chennai Corporation in March 2021. We estimated the sample size to be 203 per strata (slum and non-slum). We used a simple random sampling technique to select 20 locations using a digital map in the slum and non-slum areas. After reaching the location chosen, we selected 10 consecutive households and one adult (≥18 years of age) from each household. We used a validated, semi-structured questionnaire for collecting data regarding knowledge, attitudes, and practices for mask use. We estimated proportions and 95% CI for key variables and compared the variables between slums and non-slums. Results: Of 430 participants included in the study, 51.4% were males. The mean (S.D.) age of the participants is 41.1 (14.6) years. The majority (86.7%) of the participants felt that wearing a mask helped in reducing the spread of coronavirus and the knowledge differed (p-value < 0.05) between the slum (81.4%) and non-slum (92.3%). Nearly half (46.5%) of the participants did not like being forced to wear the mask. About 63.9% of the participants reported the practice of mask use while going out which was similar across slums and non-slums. Conclusion: Although the knowledge regarding mask use was good among the public, the attitude was unfavorable. We suggest continuous reinforcement by spreading awareness and educating the community on the appropriate use of the mask.

We estimated the effectiveness of two doses of the ChAdOx1 nCoV-19 (Covishield) vaccine against any COVID-19 infection among individuals ≥45 years in Chennai, Tamil Nadu, India. A community-based cohort study was conducted from May to September 2021 in a selected geographic area in Chennai. The estimated sample size was 10,232. We enrolled 69,435 individuals, of which 21,793 were above 45 years. Two-dose coverage of Covishield in the 18+ and 45+ age group was 18% and 31%, respectively. Genomic analysis of 74 out of the 90 aliquots collected from the 303 COVID-19-positive individuals in the 45+ age group showed delta variants and their sub-lineages. The vaccine's effectiveness against COVID-19 disease in the ≥45 age group was 61.3% (95% CI: 43.6-73.4) at least 2 weeks after receiving the second dose of Covishield. We demonstrated the effectiveness of two doses of the ChAdOx1 vaccine against the delta variant in the general population of Chennai. We recommend similar future studies considering emerging variants and newer vaccines. Two-dose vaccine coverage could be ensured to protect against COVID-19 infection.
RESUMO
INTRODUCTION: The rising cost of cancer diagnosis and treatment has imposed a huge financial burden on the affected households. Understanding the nature of this burden will help us to formulate plans to avoid financial distress among the same. OBJECTIVE: The study aims to estimate the Out of Pocket Expenditure (OOPE) for the management of selected solid cancers among the Out-Patient Department (OPD) of Regional Cancer Centre in South India and to determine the proportion of families experiencing Catastrophic Health Expenditure (CHE) due to the same. METHODS: A hospital based cross sectional analytical study was undertaken in the authors' institute in South India. 474 solid cancer patients were interviewed in OPD of Radiation Oncology by a trained data collector. Sociodemographic variables, costs incurred under various headings and expenditure details of participants were obtained. Direct Medical and Direct Non-Medical costs were calculated, and its total was used as the OOPE. Costs were presented as mean with its standard error. Incidence of CHE was calculated using the 40% threshold on the Capacity to pay and was expressed as proportions with 95% confidence interval. Appropriate statistical tests were used to look for statistically significant differences in the study groups. RESULTS: The average OOP expenditure incurred by a cancer patient was INR 35,817 (USD 523.6) for male and INR 20,496 (USD 299.6) for female. Males had a significantly higher OOPE than females. The prevalence of catastrophic health expenditure (CHE) was 61.6% at the 40% CTP threshold. Patients who used insurance schemes had higher prevalence of CHE than those who did not use insurance schemes (65.5% vs 60.7%, p value 0.351). CONCLUSION: Cancer care provided through public institutions had a low direct medical cost, but the indirect cost seemed to be extremely high. Public based financial assistance is the need of the hour to help the cancer affected families.

The rising geriatric population and the increased susceptibility of this age group to tuberculosis (TB), the deadliest single infectious agent, is bothersome for India. This study tried to explore the demographic and treatment outcome differences between the elderly (aged 60 years and above) and non-elderly TB (<60 years) patients from South India. This study was part of a large ongoing cohort study under the RePORT India consortium. Newly diagnosed TB patients recruited into the cohort between 2014 and 2018 were included in this study. Pretested and standardized questionnaire and tools were used to collect data and were stored securely for the entire cohort. Required demographic, anthropometric and treatment related variables were extracted from this database and analyzed using Stata version 14.0. Prevalence of elderly TB was summarized as percentage with 95% confidence interval (CI). Generalized linear modelling was attempted to find the factors associated with elderly TB. A total of 1,259 eligible TB patients were included into this present study. Mean (SD) of the participants in the elderly and non-elderly group was 65.8 (6.2) and 40.2 (12.0) respectively. Prevalence of elderly TB was 15.6% (95%CI: 13.6%-17.6%) with nearly 71% belonging to 60-69 age category. Male sex, OBC caste, poor education, unemployment, marriage, alcohol consumption and unable to work as per Karnofsky score were found to be significantly associated with an increased prevalence of elderly TB. Unfavorable outcomes (12% vs 6.5%, p value: 0.018), including death (9.3% vs 3.4%, p value: 0.001) were significantly higher among the elderly group when compared to their non-elderly counterparts. The current TB programme should have strategies to maintain follow up with due attention to adverse effects, social support and outcomes. Additional research should focus on predictors for unfavorable outcomes among the elderly TB group and explore ways to handle the same. Rendering adequate social support from the health system side and family side would be a good start.

PURPOSE: Government of Tamil Nadu, India, mandated the face mask wearing in public places as one of the mitigation measures of COVID-19. We established a surveillance system for monitoring the face mask usage. This study aimed to estimate the proportion of the population who wear face masks appropriately (covering nose, mouth, and chin) in the slums and non-slums of Chennai at different time points. METHODS: We conducted cross-sectional surveys among the residents of Chennai at two-time points of October and December 2020. The sample size for outdoor mask compliance for the first and second rounds of the survey was 1800 and 1600, respectively, for each of the two subgroups-slums and non-slums. In the second round, we included 640 individuals each in the slums and non-slums indoor public places and 1650 individuals in eleven shopping malls. We calculated the proportions and 95% confidence interval (95%CI) for the mask compliance outdoors and indoors by age, gender, region, and setting (slum and non-slum). RESULTS: We observed 3600 and 3200 individuals in the first and second surveys, respectively, for outdoor mask compliance. In both rounds, the prevalence of appropriate mask use outdoors was significantly lower in the slums (28%-29%) than non-slum areas (36%-35%) of Chennai (p<0.01). Outdoor mask compliance was similar within slum and non-slum subgroups across the two surveys. Lack of mask use was higher in the non-slums in the second round (50%) than in the first round of the survey (43%) (p<0.05). In the indoor settings in the 2nd survey, 10%-11% among 1280 individuals wore masks appropriately. Of the 1650 observed in the malls, 947 (57%) wore masks appropriately. CONCLUSION: Nearly one-third of residents of Chennai, India, correctly wore masks in public places. We recommend periodic surveys, enforcement of mask compliance in public places, and mass media campaigns to promote appropriate mask use.

OBJECTIVES: We undertook this review to assess the impact of pricing strategies on brand choice, loyalty and quitting behaviour in Global South countries. METHODS: We systematically retrieved articles from Medline, CENTRAL, ScienceDirect, Google Scholar from inception up to January 2020. Studies which reported tobacco industry's pricing strategies were eligible. We summarized the data as themes and codes using the principles of inductive qualitative thematic analysis within structured rational constructivist framework. RESULTS: In total, 13 studies met inclusion criteria were included. Major strategies adopted by tobacco industries to tackle the pricing and taxation changes were increased tax absorption, differential taxation based on price, cigarette length/size which ensures modest increase in the net price of cigarettes. This in turn influences the tobacco users in terms of brand loyalty and switching as they prefer to stay with factory-made cigarettes or shift to a cheaper alternative or illegal product rather than decreasing/quitting tobacco use. CONCLUSIONS: Absorption of excise tax and differential taxation are the common pricing strategies adopted by tobacco industries in Global South. These strategies together with external determinants impact the price-related tobacco control interventions.

OBJECTIVE: This review was done to determine the prevalence of metabolic syndrome (MS) among adult general population in India. We also wanted to find the gender, setting, and region-wide distribution of MS in India. METHODS: We conducted systematic searches in various databases including Medline, ScienceDirect, Cochrane library and Google Scholar from inception until August 2019. We included studies conducted in India reporting the prevalence of MS among adults aged 18 years or more. We used the Newcastle Ottawa scale to assess the quality of included studies. We carried out a meta-analysis with random-effects model and reported pooled prevalence with 95% confidence intervals (CIs). We used the Funnel plot to assess publication biases. RESULTS: In total, we analysed 113 data from 111 studies with 133,926 participants. Majority of the included studies (76 out of 111) had low risk of bias. We found significant heterogeneity among the included studies (p<0.001). We also found a symmetrical funnel plot indicating an absence of publication bias. The prevalence of MS among adult population in India was 30% (95%CI: 28%-33%). There was a steady increase in the burden across the age groups from 13% (18-29 years group) to 50% (50-59 years). We also found that people living in urban areas (32%; 95%CI: 29%-36%) had higher prevalence when compared to tribal (28%; 95%CI: 21%-36%) or rural adults (22%; 95%CI: 20%-25%). Gender distribution of MS showed that the females had higher prevalence (35%; 95%CI: 31%-38%) when compared to males 26% (95%CI: 22%-29%). CONCLUSION: Almost one in three adults in India suffer from MS. Females, people living in urban areas and in northeast region had higher prevalence of MS. Development and implementation of policies and protocols for the screening of MS would enable us in early diagnosis and treatment with special focus towards the vulnerable and high-risk groups.

BACKGROUND: Trends in morbidity and mortality due to noncommunicable diseases (NCDs) are rising because of poor control status. Medication nonadherence is one of the most common and modifiable causes of inadequate control status. OBJECTIVES: To determine the prevalence of drug adherence among patients with NCD in rural Puducherry. METHODS: A facility-based cross-sectional study was done among 260 patients with NCD receiving treatment from rural primary health center in Puducherry during February and March 2018. Information regarding sociodemographic profile and household was collected using pretested semi-structured questionnaire. Morisky Medication Adherence Scale was done to assess the adherence. We calculated adjusted prevalence ratios (aPRs) to identify the factors associated with medication adherence. RESULTS: Among the 260 participants, 42.7% belonged to elderly age group; 66.2% were females; 44% did not have any formal education; 70% were unemployed. The majority were suffering from hypertension (71.2%) followed by diabetes (56.2%). This study found that almost one-third (32.7%) of the study participants were not properly adherent to medications. Elderly [aPR 2.51 95% confidence interval (CI): 1.70-3.70] and female participants (aPR 1.64 95% CI: 1.04-2.58) were found to have more chance being nonadherent to medications after adjusting for possible confounding variables. CONCLUSION: This study reported that almost one-third of the study participants were nonadherent to medications. Elderly age group and female gender were found to be the determinants of nonadherence. Corrective measures need to be started at patient level first by motivating and educating them regarding the importance of drug intake.
