Oral health status of prisoners in India: A systematic review and meta-analysis.

AIMS: Given the high prevalence of oral health problems among prisoners, the goal of this systematic review is to provide a better knowledge of the scope of this problem. METHODS: Electronic searches of PubMed/MEDLINE, Embase, Scopus, and Google Scholar were performed. Studies that investigated inmates aged 18 or older with oral health problems were eligible. Variables reported in four or less studies were described narratively. Conversely, for variables reported in more than four studies, a meta-analysis was performed using random effect model. Furthermore, meta-regression and sensitivity analysis is also performed to evaluate moderator effect on outcome. Doi and LFT index is applied to assess publication bias. RESULTS: Out of 494 results, 12 studies were included. The pooled prevalence of caries among prisoners is 78.42% (59.48%-92.58%). On meta-regression, the prevalence of caries appears to be lower in studies with a higher male percentage; however, non-significant (p = .079) due to small sample size. Community periodontal index (CPI) scores revealed periodontal disease, with scores of 3 and 4. Moreover, a significant need for oral hygiene instruction, prosthesis, extraction, and tooth ache, periodontal disease, oral mucosal lesions, leucoplakia, attrition, abrasion, bruxism, and smoking behaviors were also reported. CONCLUSION: Poor oral health status in the incarcerated population highlights the urgent need for comprehensive oral health intervention in prisons.

Diagnostic Accuracy of Screening of Lip and Oral Cavity Cancers or Potentially Malignant Disorders (PMD) by Frontline Workers: A Systematic Review and Meta-Analysis.

BACKGROUND: Oral cancer screening strategies help reduce associated mortality and could be performed by a trained frontline health worker (FHW). The present review aims to assess the diagnostic accuracy of commonly used screening modalities for oral cancer performed by FHW in apparently healthy individuals. METHODS: Electronic databases PubMed, Scopus, Embase, Cochrane Library, and Google Scholar, were searched. The review included studies conducted where apparently healthy adult individuals were screened by the FHW for cancer or PMD of the lip and oral cavity by any of the four commonly used techniques - Conventional Oral Examination (COE), toluidine blue staining (TBS), Oral Cytology (OC), and Chemiluminescent Illumination (CLI). FINDINGS: A total of 2,413 potentially relevant articles were retrieved from the search, among which five studies for COE were included in the review. Four out of those five studies were done before the year 2000. None of the studies fitted the inclusion criteria for TBS, OC, and CLI. Pooled sensitivity of oral screening by COE performed by an FHW (n=5) was 88.8% (95% CI: 71.6-96.1), whereas pooled specificity was 91.9% (95% CI: 78.3-97.3). On subgroup analysis, the pooled sensitivity and specificity of studies where the prevalence of disease was <50% (n=4) was 84.5% (95% CI: 62.6 - 94.7) and 94.1% (95% CI: 82.2 - 98.2), respectively. INTERPRETATION: COE by trained FHW had high pooled sensitivity and specificity for screening of oral cancer and PMDs. The screening techniques TBS, OC, and CLI, were not studied for mass screening by trained FHW. COE by trained FHW could be utilized for oral screening in limited-resource settings. However, the FHW should be sufficiently trained to get the desired benefits of early detection. FUNDING: Department of Health Research, Ministry of Health & Family Welfare, Government of India.

Hyperglycemia and steroid use increase the risk of rhino-orbito-cerebral mucormycosis regardless of COVID-19 hospitalization: Case-control study, India.

BACKGROUND: In the ongoing COVID-19 pandemic, an increased incidence of ROCM was noted in India among those infected with COVID. We determined risk factors for rhino-orbito-cerebral mucormycosis (ROCM) post Coronavirus disease 2019 (COVID-19) among those never and ever hospitalized for COVID-19 separately through a multicentric, hospital-based, unmatched case-control study across India. METHODS: We defined cases and controls as those with and without post-COVID ROCM, respectively. We compared their socio-demographics, co-morbidities, steroid use, glycaemic status, and practices. We calculated crude and adjusted odds ratio (AOR) with 95% confidence intervals (CI) through logistic regression. The covariates with a p-value for crude OR of less than 0·20 were considered for the regression model. RESULTS: Among hospitalised, we recruited 267 cases and 256 controls and 116 cases and 231 controls among never hospitalised. Risk factors (AOR; 95% CI) for post-COVID ROCM among the hospitalised were age 45-59 years (2·1; 1·4 to 3·1), having diabetes mellitus (4·9; 3·4 to 7·1), elevated plasma glucose (6·4; 2·4 to 17·2), steroid use (3·2; 2 to 5·2) and frequent nasal washing (4·8; 1·4 to 17). Among those never hospitalised, age ≥ 60 years (6·6; 3·3 to 13·3), having diabetes mellitus (6·7; 3·8 to 11·6), elevated plasma glucose (13·7; 2·2 to 84), steroid use (9·8; 5·8 to 16·6), and cloth facemask use (2·6; 1·5 to 4·5) were associated with increased risk of post-COVID ROCM. CONCLUSIONS: Hyperglycemia, irrespective of having diabetes mellitus and steroid use, was associated with an increased risk of ROCM independent of COVID-19 hospitalisation. Rational steroid usage and glucose monitoring may reduce the risk of post-COVID.

Dental caries prevalence among 5- to 15-year-old children from SEAR countries of WHO: A systematic review and meta-analysis.

OBJECTIVES: The aim of this review was to estimate the prevalence of dental caries in children 5-15 years of age in the countries of the South-East Asia Region (SEAR) of World Health Organization (WHO) and to describe the different caries indices used in these population-based studies. MATERIALS AND METHODS: A systematic search was carried out in two databases from 1st January 2005 to 31st May 2015. Studies were included if they met the predetermined eligibility criteria. Quality assessment was done with eight-item checklist. Meta-analysis was done for 5, 12, 15, and 6-15 years age group using software STATA version 12. RESULTS: The search strategy yielded 265 unique articles of which 36 met the inclusion criteria included for the review. Data were available for only three SEAR countries. The quality of the majority of the studies ranged from moderate to high. Heterogeneity between the studies was high (I2 > 98%). Variation in dental caries prevalence was found among different ages and among different SEAR countries. The most commonly used index for measuring dental caries was the dentition status of the 1997 WHO criteria. CONCLUSION: Dental caries continues to be a prominent oral health problem among children in the SEAR countries with huge variation in the prevalence across ages and countries. This review results can be used to update the "WHO Oral Health Country/Area Profile Program" for dental caries among children for SEAR.

Efficacy of green tea-based mouthwashes on dental plaque and gingival inflammation: A systematic review and meta-analysis.

OBJECTIVES: The purpose of this study was to conduct a systematic review and if appropriate a meta-analysis of the efficacy of daily rinsing with green tea-based mouthwashes in terms of plaque index (PI) and/or gingival index (GI) as compared to other mouthwashes in plaque-induced gingivitis patients. MATERIALS AND METHODS: MEDLINE, Cochrane Central Register of Controlled Trials, IndMed, Google Scholar, and major journals were searched for studies up to December 2016. A comprehensive search strategy was designed, and the eligible articles were independently screened for eligibility by two reviewers. Randomized controlled trials in which individuals were intervened with oral mouthwashes of interest were included. Where appropriate, a meta-analysis was performed and standardized mean differences (SMDs) for GI and PI were calculated. RESULTS: A total of 9 articles out of the 311 titles met the eligibility criteria. A meta-analysis was performed for five studies that compared green tea-based mouthwashes with chlorhexidine (CHX). The SMD for PI was -0.14 (95% CI: -1.70, 1.43; P = 0.86 and I2 = 94%), while that for GI was 0.43 ((95% CI: -0.63, 1.49; P = 0.43, I2 = 89%). Both these estimates suffered from significant heterogeneity. For both PI and GI, two studies were in favor of green tea while three studies were in favor of CHX. CONCLUSIONS: Green tea-based mouthwashes can be considered an alternative to CHX mouthwashes in sustaining oral hygiene, especially because of the added advantages provided by such herbal preparations.

Pre-treatment factor structures of the Montgomery and Åsberg Depression Rating scale as predictors of response to escitalopram in Indian patients with non-psychotic major depressive disorder.

BACKGROUND: Major Depressive Disorder (MDD) is a broad heterogeneous construct resolving into several symptom-clusters by factor analysis. The aim was to find the factor structures of MDD as per Montgomery and Asberg Depression Rating Scale (MADRS) and whether they predict escitalopram response. METHODS: In a longitudinal study at a tertiary institute in north India, 116 adult out-patients with non-psychotic unipolar MDD were assessed with MADRS before and after treatment with escitalopram (10-20mg) over 6-8 weeks for drug response. RESULTS: For total 116 patients pre-treatment four factor structures of MADRS extracted by principal component analysis with varimax rotation altogether explained a variance of 57%: first factor 'detachment' (concentration difficulty, lassitude, inability to feel); second factor 'psychic anxiety' (suicidal thoughts and inner tension); third 'mood-pessimism' (apparent sadness, reported sadness, pessimistic thoughts) and fourth 'vegetative' (decreased sleep, appetite). Eighty patients (68.9%) who completed the study had mean age 35.37±10.9 yrs, majority were male (57.5%), with mean pre-treatment MADRS score 28.77±5.18 and majority (65%) having moderate severity (MADRS <30). Among them 56 (70%) responded to escitalopram. At the end of the treatment there were significant changes in all the 4 factor structures (p<0.01). Vegetative function was an important predictor of response (p<0.01, odd's ratio: 1.3 [1.1-1.6] 95% CI). Melancholia significantly predicted non-response (p=0.04). CONCLUSIONS: Non-psychotic unipolar major depression having moderate severity in north Indian patients as per MADRS resolved into four factor-structures all significantly improved with adequate escitalopram treatment. Understanding the factor structure is important as they can be important predictor of escitalopram response.

Sensitivity and Specificity of Pulse Oximetry and Ankle-Brachial Index for Screening Asymptomatic Peripheral Vascular Diseases in Type 2 Diabetes Mellitus.

OBJECTIVES: To compare pulse oximetry and Ankle-Brachial Index (ABI) with duplex ultrasonography as reference standard to determine the diagnostic accuracy for screening asymptomatic PVD in type 2 diabetes mellitus. METHODS: This cross-sectional study was conducted in 2012 at tertiary hospital in Madurai among diabetic patients attending the medicine outpatient department (OPD). Type 2 Diabetes Mellitus patients, asymptomatic with regards to symptoms and signs of PVD, aged above 40 years were included. Pulse Oximetry was performed using a pulse oximeter and ABI using sphygmomanometer cuffs and duplex ultrasonography of femoral, popliteal, tibial, posterior tibial and dorsalis pedis arteries. A diagnosis of PVD was based on: monophasic waveforms in any artery by duplex ultrasonography, toe saturation being less than finger saturation by >2% or if foot saturation decreased by >2% in an elevated position and an ABI <0.9. RESULTS: Among 120 patients included in the study, prevalence of PVD was 22.5% (95% CI: 15.9, 30.8). The PVD group had a higher proportion of elderly, males, current smokers, long-standing diabetics and comorbidities. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of pulse oximetry were 74.1% (95% CI: 55.3, 86.8), 95.7% (89.4, 98.3), 83.3% (64.1, 93.3) and 92.7% (85.7, 96.4) respectively, while those of ABI were 70.3% (51.5, 84.2), 87.1 (78.8, 92.5), 61.3% (43.8, 76.3) and 91.0% (83.3, 95.4) respectively. Parallel testing had net sensitivity increased to 92.3% and net specificity decreased to 83.3%. Performances did not differ across the subgroups. CONCLUSIONS: Pulse oximetry was atleast as good as ABI for the screening for asymptomatic PVD among diabetics.

Trends of Smokeless Tobacco use among Adults (Aged 15-49 Years) in Bangladesh, India and Nepal.

BACKGROUND: Smokeless tobacco (SLT) has long been realized as an important component of the fight for global tobacco control. It still remains a major problem in countries like India, Bangladesh and Nepal. The objective of this study was to estimate the trends of SLT use in three countries of the SEARO WHO office. MATERIALS AND METHODS: We used data from national surveys in three countries (Bangladesh, India and Nepal) to estimate trends in prevalence of current SLT use. All available nationally representative data sources were used. Estimates were weighted, age standardized and given along with 95% confidence intervals. Significance of linear trend in prevalence over time was tested using the Cochrane-Armitage test for trend. A p value of less than 0.05 was considered statistically significant. RESULTS: We identified three surveys for Bangladesh, three for India and four for Nepal that met the selection criteria (such as Demographic and Health Surveys, WHO-STEPwise approach to Surveillance and Global Adult Tobacco Surveys). A significantly increasing trend was noticed in the prevalence of current SLT use among Bangladeshi men (20.2% to 23%, p=0.03). In India, a similar significantly increasing trend was seen among men (27.1% to 33.4%, p<0.001) and women (10.1% to 15.7%, p<0.001). In Nepal, there was a no significant trend among both men (39.1% to 31.6%, p=0.11) and women (5.6% to 4.7%, p=0.49). CONCLUSIONS: In the study countries SLT use has remained at alarmingly high levels. Usage trends do not show any signs of decline in spite of control efforts. Tobacco control measures should focus more on controlling SLT use.

Pre-treatment practices among patients attending an Animal Bite Management clinic at a primary health centre in Haryana, North India.

A cross-sectional study was carried out at the Animal Bite Management (ABM) clinic in a primary health centre in the Faridabad district of Haryana. Information about socio-demographic characteristics, animal bite exposure and pre-treatment practices was obtained. Clinical examination determined the severity of the bite. All 619 patients who reported to the ABM clinic during January 2011 to December 2012 were included. Out of the total, 38% had applied chilli-oil paste, and 4% antiseptics to the wound as pre-treatment; only 30.6% had washed the wound with water. There was a direct association between traditional pre-treatment practices and delay in seeking treatment for animal bites which was statistically significant (P = 0.01). Health education of the general population with culturally appropriate Information, Education and Communication material is therefore a necessary strategy to reduce delay in seeking appropriate treatment.

Prevalence and sociodemographic determinants of tobacco use in four countries of the World Health Organization: South-East Asia region: findings from the Global Adult Tobacco Survey.

INTRODUCTION: Tobacco use is a leading cause of deaths and Disability Adjusted Life Years lost worldwide, particularly in South-East Asia. Health risks associated with exclusive use of one form of tobacco alone has a different health risk profile when compared to dual use. In order to tease out specific profiles of mutually exclusive categories of tobacco use, we carried out this analysis. METHODS: The Global Adult Tobacco Survey (GATS) data was used to describe the profiles of three mutually exclusive tobacco use categories ("Current smoking only," "Current smokeless tobacco [SLT] use only," and "Dual use") in four World Health Organization South-East Asia Region countries, namely Bangladesh, India, Indonesia and Thailand. GATS was a nationally representative household-based survey that used a stratified multistage cluster sampling design proportional to population size. Prevalence of different forms of usage were described as proportions. Logistics regression analyses was performed to calculate odds ratios (OR) with 95% confidence intervals. All analyses were weighted, accounted for the complex sampling design and conducted using SPSS version 18. RESULTS: The prevalence of different forms of tobacco use varied across countries. Current tobacco use ranged from 27.2% in Thailand to 43.3% in Bangladesh. Exclusively smoking was more common in Indonesia (34.0%) and Thailand (23.4%) and less common in Bangladesh (16.1%) and India (8.7%). Exclusively using SLT was more common in Bangladesh (20.3%) and India (20.6%) and less common on Indonesia (0.9%) and Thailand (3.5%). Dual use of smoking and SLT was found in Bangladesh (6.8%) and India (5.3%), but was negligible in Indonesia (0.8) and Thailand (0.4%). Gender, age, education and wealth had significant effects on the OR for most forms of tobacco use across all four countries with the exceptions of SLT use in Indonesia and dual use in both Indonesia and Thailand. In general, the different forms of tobacco use increased among males and with increasing age; and decreased with higher education and wealth. The results for urban versus rural residence were mixed and frequently not significant once controlling for the other demographic factors. CONCLUSION: This study addressed the socioeconomic disparities, which underlie health inequities due to tobacco use. Tobacco control activities in these countries should take in account local cultural, social and demographic factors for successful implementation.

Evaluation of state-run STI/RTI clinics in the state of Haryana, India through a supportive supervision approach.

INTRODUCTION: Sexually transmitted infections (STIs) are an important public health problem because of their adverse effects on reproductive health of men and women. About 5% of adult population in India suffers from STIs. To tackle this issue the government has set up reproductive tract infection (RTI) clinics across the country. AIMS: To assess the effect of supportive supervision on the quality of services provided in STI/RTI clinics in the state of Haryana, India. SETTINGS AND DESIGN: Selected state-run STI/RTI clinics, facility-based pre- and post evaluation study. MATERIAL AND METHODS: Sixteen STI/RTI clinics were selected for the study, including six from government facilities and 10 from targeted intervention sites across five districts of Haryana. From each of the selected sites one physician in-charge was interviewed twice with an interval of 2-3 months using pretested formats. Scores were given in selected domains of STI/RTI management for each visit and the improvement was assessed. STATISTICAL ANALYSIS: Wilcoxon signed rank test. RESULTS: A total of 16 physicians one from each site were interviewed. Improvement in mean score of the physicians for knowledge about STI/RTI was 3.6 points. Similarly for skills score, which measured the physicians' skill in various domains of running STI/RTI clinics, the mean improvement was 3.1 points. Both the improvements were statistically significant (P < 0.001). CONCLUSIONS: Supportive supervision proved to be a useful tool for monitoring and improving the quality of services provided by the STI/RTI clinics.

Correlates of Intention to Use Condom among Male Migrant Factory Workers in Northern India.

OBJECTIVE: Consistent condom use among high-risk groups, which in turn are dependant on favourable condom use intention is important for the success of HIV/AIDS prevention programmes. We aimed to determine intention to use condom and delineate their correlates in a sample of male migrant workers in northern India. MATERIALS AND METHODS: This was a cross-sectional facility based survey conducted in 2011. Inclusion criteria were: male migrant workers aged ≥18 years, who were born outside Haryana, who had moved to current location after 15 years of age, who had worked in the current factory for at least one year and who were able to give valid consent. Face-to-face interviews were conducted with semi-structured questionnaire. Since this analysis was a secondary objective of a larger migrant study, sample size was not calculated separately. Intention to use condom was measured on a five point Likert scale and expressed as a linear score (higher the score more unfavourable the intention). A linear regression analysis was performed to identify factors independently associated with unfavourable intention. RESULTS: Mean (SD) score for intention to use condom was 10.4 (3.4). Unfavourable intention was associated with men who had migrated to greater number of places, who had lesser HIV/AIDS knowledge, who had never used condom and who had not used condom at last non-spousal sex. The model had an adjusted R-square value of 0.63 and was statistically significant (F = 41.9, p < 0.001). CONCLUSION: Male migrant workers had unfavourable intention to use condom. This intention could be favourably modified by behaviour change communication through already existing targeted intervention platforms, focussing attention on groups with higher mobility, lower education, lower HIV/AIDS knowledge and inconsistent condom use.

Temporal dimension in reference standard misclassification - a concept note.

In situations of diagnostic tests studies where the gold standard (GS) test is not absolutely perfect, validity measures of index tests vary in subgroups with varying disease prevalence. This is called reference standard misclassification. Although this is widely known, little is explained about the variations in the performance of index tests when the validity of the GS test itself varies with the time duration of illness. This article attempts to expand the concept of reference standard misclassification specifically on the effect of time dependence of diagnostic tests. A brief literature review is also presented which documents the existent knowledge among researchers about the concept and the methods they usually employ to adjust. A list of solutions which can address the issue has also been discussed to enable researchers to design and analyse diagnostic test studies in better ways.

Influence of alcohol on condom use pattern during non-spousal sexual encounter in male migrant workers in north India.

CONTEXT: Migrant workers constitute an important risk group for Human Immunodeficiency Virus/Acquired Immuno-Deficiency Syndrome transmission in India. Alcohol consumption before sexual intercourse has been postulated to influence condom use practices. This study aimed to assess this association with regard to non-spousal sexual encounters among male migrant workers in northern India. MATERIALS AND METHODS: A cross-sectional facility-based survey was conducted in 2011. Male migrant workers aged ≥18 years, who were born outside Haryana, who had moved to the current location after 15 years of age,had worked in the current factory for at least 1 year, who were willing to participate and were able to give written, informed consent were included in the study. A consecutive sampling was performed. Descriptive, bivariate and multiple logistic regression analyses were carried out. RESULTS: A total of 162 participants reported having experienced non-spousal sexual encounters in the last 1 year. The proportion of men who reported not having used a condom at their last non-spousal sexual encounter was 59.3%, and 78.4% of the men reported having consumed alcohol in the last 1 year. About 48.1% of men reported having consumed alcohol before their last non-spousal sexual encounter. Men who consumed alcohol were three times more likely to not use a condom at their last non-spousal sexual encounter (OR = 3.1, 95% CI: 1.5-6.4). This association persisted even after adjusting for relevant confounders. CONCLUSION: Alcohol consumption had a negative influence on condom use during non-spousal sexual encounter among male migrant workers. An integrated approach to promote condom use and reduce alcohol consumption among migrant men needs to be undertaken through targeted intervention strategies.

Prevalence of hypertension in Indian tribes: a systematic review and meta-analysis of observational studies.

INTRODUCTION: In India there is an increasing trend in hypertension prevalence among the general population. Studies have shown that tribal populations in India are also experiencing this burden. OBJECTIVE: The aim was to estimate the pooled prevalence of primary hypertension among adult tribal populations of India. METHODS: A systematic search was conducted in MEDLINE, IndMed, Web of Science, Google Scholar and major journals for studies published between 1981 and 2011. Two authors independently reviewed the studies, did quality assessment and extracted data in pre-coded spread-sheets. Pooled estimates of prevalence of hypertension were calculated using DerSimonian-Laird random effects model. Subgroup and sensitivity analyses and meta-regression were performed. RESULTS: Twenty studies or 53 subpopulations with 64 674 subjects were included in final review. The pooled estimate of hypertension prevalence was 16.1% (95% CI: 13.5, 19.2). There was significant heterogeneity among the studies (I2 = 99% and Q = 4624.0, df  = 53, p<0.001). Subgroup analyses showed that year of study, acculturation status, special features, and BP measurement techniques significantly influenced prevalence, but after meta-regression analyses, 'decade of study' remained the only covariate that significantly and independently influenced prevalence (R2 = 0.57, Q = 119.2, df  = 49, p value <0.001). CONCLUSION: An increasing trend was found in the prevalence of hypertension in adult tribal populations across three decades. Although acculturation was probably the underlying agent that caused this increase, other unmeasured factors that need further research were also important. Concerned policy makers should focus on the changing health needs of tribal communities.

High neonatal mortality rates in rural India: what options to explore?

The neonatal mortality rate in India is amongst the highest in the world and skewed towards rural areas. Nonavailability of trained manpower along with poor healthcare infrastructure is one of the major hurdles in ensuring quality neonatal care. We reviewed case studies and relevant literature from low and middle income countries and documented alternative strategies that have proved to be favourable in improving neonatal health. The authors reiterate the fact that recruiting and retaining trained manpower in rural areas by all means is essential to improve the quality of neonatal care services. Besides this, other strategies such as training of local rural healthcare providers and traditional midwives, promoting home-based newborn care, and creating community awareness and mobilization also hold enough potential to influence the neonatal health positively and efforts should be made to implement them on a larger scale. More research is demanded for innovations such as "m-health" and public-private partnerships as they have been shown to offer potential in terms of improving the standards of care. The above proposed strategy is likely to reduce morbidity among neonatal survivors as well.
