An epidemiological overview of child sexual abuse.

Mannat M Singh; Shradha S Parsekar; Sreekumaran Nair

Child sexual abuse (CSA) is a universal problem with grave life-long outcomes. The estimates vary widely depending on the country under study, the definitions used, the type of CSA studied, the extent of coverage, and quality of data. This study intended to assess the magnitude and the issues related to CSA. We searched databases such as PubMed, Google scholar, web (newspaper reports), and government websites. The relevant data was extracted from these sources for gathering evidence on CSA and secondary data analysis was done. The prevalence of CSA was found to be high in India as well as throughout the world. CSA is an extensive problem and even the lowest prevalence includes a huge number of victims. It also has various adverse effects on the psychological, physical, behavioral, and interpersonal well-being of the victim. Hence, stringent measures should be taken for the prevention and control of this hidden public health issue.

The practice of Ayurveda, the traditional medicine of India, is based on the concept of three major constitutional types (Vata, Pitta and Kapha) defined as “Prakriti”. To the best of our knowledge, no study has convincingly correlated genomic variations with the classification of Prakriti. In the present study, we performed genome-wide SNP (single nucleotide polymorphism) analysis (Affymetrix, 6.0) of 262 well-classified male individuals (after screening 3416 subjects) belonging to three Prakritis. We found 52 SNPs (p ≤ 1 × 10−5) were significantly different between Prakritis, without any confounding effect of stratification, after 106 permutations. Principal component analysis (PCA) of these SNPs classified 262 individuals into their respective groups (Vata, Pitta and Kapha) irrespective of their ancestry, which represent its power in categorization. We further validated our finding with 297 Indian population samples with known ancestry. Subsequently, we found that PGM1 correlates with phenotype of Pitta as described in the ancient text of Caraka Samhita, suggesting that the phenotypic classification of India’s traditional medicine has a genetic basis; and its Prakriti-based practice in vogue for many centuries resonates with personalized medicine.

BackgroundDNA methylation and its perturbations are an established attribute to a wide spectrum of phenotypic variations and disease conditions. Indian traditional system practices personalized medicine through indigenous concept of distinctly descriptive physiological, psychological and anatomical features known as prakriti. Here we attempted to establish DNA methylation differences in these three prakriti phenotypes.MethodsFollowing structured and objective measurement of 3416 subjects, whole blood DNA of 147 healthy male individuals belonging to defined prakriti (Vata, Pitta and Kapha) between the age group of 20-30years were subjected to methylated DNA immunoprecipitation (MeDIP) and microarray analysis. After data analysis, prakriti specific signatures were validated through bisulfite DNA sequencing.ResultsDifferentially methylated regions in CpG islands and shores were significantly enriched in promoters/UTRs and gene body regions. Phenotypes characterized by higher metabolism (Pitta prakriti) in individuals showed distinct promoter (34) and gene body methylation (204), followed by Vata prakriti which correlates to motion showed DNA methylation in 52 promoters and 139 CpG islands and finally individuals with structural attributes (Kapha prakriti) with 23 and 19 promoters and CpG islands respectively. Bisulfite DNA sequencing of prakriti specific multiple CpG sites in promoters and 5′-UTR such as; LHX1 (Vata prakriti), SOX11 (Pitta prakriti) and CDH22 (Kapha prakriti) were validated. Kapha prakriti specific CDH22 5′-UTR CpG methylation was also found to be associated with higher body mass index (BMI).ConclusionDifferential DNA methylation signatures in three distinct prakriti phenotypes demonstrate the epigenetic basis of Indian traditional human classification which may have relevance to personalized medicine.

BACKGROUND Paddy farming is one of the main occupations in coastal South India. Dermatological problems in paddy field workers have not received much attention. AIM The purpose of this study was to study the dermatoses of the exposed parts of the body, viz. face, hands, and feet, in paddy field workers. METHODS Three hundred and forty-one workers were questioned and clinical findings noted. Scrapings for bacterial and fungal examination were taken by random selection. RESULTS Seventy-three per cent had work-related itching. Melasma was the commonest facial lesion (41.1%). The main problems on the hands were hyperkeratosis (26.4%), nail dystrophy (15.2%) and paronychia (8.8%). Common feet dermatoses included nail dystrophy (57.1%), pitted keratolysis (42.5%) and fissuring (23.5%). Common aerobic and anaerobic bacteria isolated from pitted keratolysis and intertrigo were Klebsiella and Clostridium species. Aspergillus species were the commonest fungus grown from intertrigo. CONCLUSIONS Occupational dermatoses are common in paddy field workers.

Background: Constitutional type of an individual or prakriti is the basic clinical denominator in Ayurveda, which defines physical, physiological, and psychological traits of an individual and is the template for individualized diet, lifestyle counseling, and treatment. The large number of phenotype description by prakriti determination is based on the knowledge and experience of the assessor, and hence subject to inherent variations and interpretations. Objective: In this study we have attempted to relate dominant prakriti attribute to body mass index (BMI) of individuals by assessing an acceptable tool to provide the quantitative measure to the currently qualitative ayurvedic prakriti determination. Materials and Methods: The study is cross sectional, multicentered, and prakriti assessment of a total of 3416 subjects was undertaken. Healthy male, nonsmoking, nonalcoholic volunteers between the age group of 20-30 were screened for their prakriti after obtaining written consent to participate in the study. The prakriti was determined on the phenotype description of ayurvedic texts and simultaneously by the use of a computer-aided prakriti assessment tool. Kappa statistical analysis was employed to validate the prakriti assessment and Chi-square, Cramer′s V test to determine the relatedness in the dominant prakriti to various attributes. Results: We found 80% concordance between ayurvedic physician and software in predicting the prakriti of an individual. The kappa value of 0.77 showed moderate agreement in prakriti assessment. We observed a significant correlations of dominant prakriti to place of birth and BMI with Chi-square, P < 0.01 (Cramer′s V-value of 0.156 and 0.368, respectively). Conclusion: The present study attempts to integrate knowledge of traditional ayurvedic concepts with the contemporary science. We have demonstrated analysis of prakriti classification and its association with BMI and place of birth with the implications to one of the ways for human classification.

Body mass index (BMI) is a non-invasive measurement of obesity. It is commonly used for assessing adiposity and obesity-related risk prediction. Genetic differences between ethnic groups are important factors, which contribute to the variation in phenotypic effects. India inhabited by the first out-of-Africa human population and the contemporary Indian populations are admixture of two ancestral populations; ancestral north Indians (ANI) and ancestral south Indians (ASI). Although ANI are related to Europeans, ASI are not related to any group outside Indian-subcontinent. Hence, we expect novel genetic loci associated with BMI. In association analysis, we found eight genic SNPs in extreme of distribution (P⩽3.75 × 10−5), of which WWOX has already been reported to be associated with obesity-related traits hence excluded from further study. Interestingly, we observed rs1526538, an intronic SNP of THSD7A; a novel gene significantly associated with obesity (P=2.88 × 10−5, 8.922 × 10−6 and 2.504 × 10−9 in discovery, replication and combined stages, respectively). THSD7A is neural N-glycoprotein, which promotes angiogenesis and it is well known that angiogenesis modulates obesity, adipose metabolism and insulin sensitivity, hence our result find a correlation. This information can be used for drug target, early diagnosis of obesity and treatment.

Attibele Palaksha Manjunath; Nidhika Chhabra; Shivarudraiah Girija; Sreekumaran Nair

OBJECTIVE The intraperitoneal route of analgesia has been studied over the years for effective perioperative pain relief during minimally invasive surgery, but there were conflicting reports of the use of intraperitoneal analgesic administration and moreover there was no consensus regarding the dose and type of drugs used. We report a randomized trial to assess the safety and effectiveness of intraperitoneal lignocaine as an intraoperative and postoperative analgesic in laparoscopic tubal ligation. STUDY DESIGN This is a double masked, randomized parallel group placebo-controlled trial of women seeking laparoscopic sterilization under local anaesthesia at a university hospital. The intervention group and placebo group received 20 ml of 0.5% lignocaine and 20 ml of isotonic saline intraperitoneally respectively. Allocation concealment was done by fixed block randomization. The participating women, the surgeon, anaesthetist, technician and the doctor who assessed the pain score were masked to the type of intervention. Intraoperative and postoperative pain was assessed by visual analogue pain scale and the scores are expressed as mean difference (95% confidence interval) between groups. Our trial is registered with the Clinical Trials Registry, India (http://www.ctri.nic.in/, CTRI/2009/091/000072). RESULTS Out of 200 women recruited, 196 were available for final analysis with 98 women in each arm. The mean difference in the intraoperative pain score at the time of tubal ligation was 3.5 cm (95% CI 2.91-4.09). The mean difference in the postoperative pain scores at half an hour was 2.9 (95% CI 2.50-3.44), 1h was 2.5 (95% CI 2.08-3.00) and 3h was 1.2 (95% CI 0.75-1.76). There was no case of adverse reaction to lignocaine. CONCLUSION Our findings show that intraperitoneal instillation of lignocaine is a safe and effective method for perioperative pain relief during laparoscopic tubal occlusion performed under conscious sedation.

Mental health literacy among late adolescents in South India: What they know and what attitudes drive them

Judith Miti Ogorchukwu; Varalakshmi Chandra Sekaran; Sreekumaran Nair; Lena Ashok

Background: Early recognition of mental health problems gives an individual the opportunity for better long-term outcomes if intervention is initiated early. Mental health literacy is a related concept which is increasingly seen as an important measure of the awareness and knowledge of mental health disorders. Aim and Objectives: This study aimed at assessing the mental health literacy, help-seeking behavior and beliefs and attitudes related to mental illnesses among adolescents attending preuniversity colleges. Materials and Methods: A cross-sectional study was conducted among randomly selected preuniversity college students (n = 916). Data were collected through self-administered questionnaires. Data were computed using STATA. Analysis and interpretation were carried out using descriptives and Chi-square test. Results: Of the 916 respondents, 54.15% were male while 45.85% were female. The majority (78.60%) of the respondents ascribed to the Hindu religion, hailed largely from rural areas (57.21%) and were mostly studying in the 11th standard (72.49%). The percentage of mental health literacy among the respondents was very low, i.e., depression was identified by 29.04% and schizophrenia/psychosis was recognized by 1.31%. The study findings indicate that adolescents preferred reaching out more to informal sources including family members such as mothers than formal sources for self than for others indicating deeply prevalent stigmatizing attitudes toward mental health conditions. Conclusions: There is a need for immediate improvement in the knowledge of adolescents on mental health literacy which suggests that programs need to be developed such that adolescents can seek help from valid resources if the need were to arise and have appropriate knowledge on whom to approach for help.

A systematic review of community-based health insurance programs in South Asia

Reshmi Bhageerathy; Sreekumaran Nair; Unnikrishnan Bhaskaran

BACKGROUND Community-based health insurance (CBHI) has been evolving as an effective means of healthcare financing in many countries of South Asia. A systematic review in this context would give a comprehensive report of the performance of these schemes in terms of improving the health-seeking behaviour of the beneficiaries enrolled for the schemes. METHODS Important databases like PubMed, Elsevier, SocINDEX (EBSCO), Cochrane Reviews, Medline and Scopus were reviewed along with relevant portals-Google Scholar, www.who.int/, www.worldbank.org and www.cochrane.org-and specific journals and discussion series with published literature in the areas of community health insurance and health microfinance. RESULTS The review finally chronicles 20 CBHI schemes from published and unpublished literature from the countries comprising South Asia. These schemes have been reviewed in terms of their enrolment process, entry point and the extent to which they have contributed to the healthcare-seeking behaviour. CONCLUSION The CBHI schemes can also serve as an alternative healthcare financing mechanism where fee-for-service and user fees have not made any impact. There have been very few studies that have tried to carry out an impact evaluation of the CBHI schemes on the target population, and more and more such studies can be a scope for further research.

Sreekumaran Nair; Leslie Lewis; Myron Anthony Godinho; Shruti Murthy; Theophilus Lakiang; Bhumika T Venkatesh

Introduction India accounts for more neonatal deaths than any other country. There is a lack of consolidated evidence from India regarding the determining factors of pneumonia in neonates. This systematic review is aimed to consolidate and appraise the evidence on risk factors and determinants of pneumonia among neonates in India. Methods and analysis This protocol is part of a project consisting of three reviews (two systematic reviews and one scoping review) and a qualitative study on neonatal pneumonia in India. English language observational studies which report risk factors and determinants of neonatal pneumonia in India will be eligible for inclusion. Electronic searching of nine databases, and hand searching will be done. Two authors will independently conduct screening (title, abstract and full-text stages), extract data and assess risk of bias. A meta-analysis is planned to be performed with random-effects model. A narrative synthesis will be used to summarise the characteristics and findings of the review, if a meta-analysis cannot be performed. If there are more than 10 studies, publication bias will be assessed. Sensitivity and subgroup analysis will performed based on data availability. The quality of our review will be assessed by using ‘Assessing the Methodological quality of Systematic Reviews’ and ‘Grades of Recommendation, Assessment, Development and Evaluation’. Ethics and dissemination The protocol of the entire project has been approved by the host institution’s ethics body (Institutional Ethics Committee, Manipal University, Manipal, India), and the ‘Health Ministry Screening Committee’ under the Ministry of Health and Family Welfare, Government of India. The study findings will be disseminated among relevant stakeholders using knowledge dissemination workshops, policy briefs, publications, etc. PROSPERO registration number CRD42016044019.
