RESUMEN

Background: West Bengal, situated in eastern India, comprising 19 districts as of 2016 and consisting of 9.13 crore population, had been one of the participating states in the National Mental Health Survey, 2015-16. Aim: To estimate the prevalence and pattern of mental disorders in a representative population in West Bengal. Materials and Methods: Based upon a multi-stage stratified random cluster sampling with probability proportionate to each stage, 2646 eligible individuals were interviewed. Standard validated instruments in Bengali like socio-demographic profiles and Mini International Neuropsychiatric Interview (MINI) version 6 were used by trained data collectors with quality monitoring as per a standardized protocol. Results: The current prevalence of mental illness in the state of West Bengal is 13.07% (12.9-13.24 95% CI), which is more than the current national average of 10.56% (10.51-10.61 95% CI). The prevalence of severe mental illness of 2.32% and suicide risk of 1.75% (1.68-1.81 95% CI) is higher than the national average. The common mental illness prevalence is 11.29 (11.13-11.45 95% CI), which is similar to the national weighted average. In West Bengal, severe mental illness is more concentrated in the rural areas in contrast to the national trend. Also, the prevalence of alcohol use disorder is 3.04 (2.96-3.13 95% CI) and epilepsy is 0.03 (0.27-0.29 95% CI), which is less than the national average. Conclusion: The prevalence of mental disorders in the state of West Bengal is higher than the national average, and for severe mental illness, the prevalence is the highest as compared to the national average.

RESUMEN

INTRODUCTION: Ayushman Bharat Pradhan Mantri Jan Aarogya Yojana (AB PM-JAY) has enabled the Government of India to become a strategic purchaser of health care services from private providers. To generate base cost evidence for evidence-based policymaking the Costing of Health Services in India (CHSI) study was commissioned in 2018 for the price setting of health benefit packages. This paper reports the findings of a process evaluation of the cost data collection in the private hospitals. METHODS: The process evaluation of health system costing in private hospitals was an exploratory survey with mixed methods (quantitative and qualitative). We used three approaches-an online survey using a semi-structured questionnaire, in-depth interviews, and a review of monitoring data. The process of data collection was assessed in terms of time taken for different aspects, resources used, level and nature of difficulty encountered, challenges and solutions. RESULTS: The mean time taken for data collection in a private hospital was 9.31 (± 1.0) person months including time for obtaining permissions, actual data collection and entry, and addressing queries for data completeness and quality. The longest time was taken to collect data on human resources (30%), while it took the least time for collecting information on building and space (5%). On a scale of 1 (lowest) to 10 (highest) difficulty levels, the data on human resources was the most difficult to collect. This included data on salaries (8), time allocation (5.5) and leaves (5). DISCUSSION: Cost data from private hospitals is crucial for mixed health systems. Developing formal mechanisms of cost accounting data and data sharing as pre-requisites for empanelment under a national insurance scheme can significantly ease the process of cost data collection.

RESUMEN

BACKGROUND: In low- and middle-income countries (LMICs), provisioning for surgical care is a public health priority. Ayushman Bharat Pradhan Mantri-Jan Aarogya Yojana (AB PM-JAY) is India's largest national insurance scheme providing free surgical and medical care. In this paper, we present the costs of surgical health benefit packages (HBPs) for secondary care in public district hospitals. METHODS: The costs were estimated using mixed (top-down and bottom-up) micro-costing methods. In phase II of the Costing of Health Services in India (CHSI) study, data were collected from a sample of 27 district hospitals from nine states of India. The district hospitals were selected using stratified random sampling based on the district's composite development score. We estimated unit costs for individual services-outpatient (OP) visit, per bed-day in inpatient (IP) and intensive care unit (ICU) stays, and surgical procedures. Together, this was used to estimate the cost of 250 AB PM-JAY HBPs. RESULTS: At the current level of utilization, the mean cost per OP consultation varied from US$4.10 to US$2.60 among different surgical specialities. The mean unit cost per IP bed-day ranged from US$13.40 to US$35.60. For the ICU, the mean unit cost per bed-day was US$74. Further, the unit cost of HBPs varied from US$564 for bone tumour excision to US$49 for lid tear repair. CONCLUSIONS: Data on the cost of delivering surgical care at the level of district hospitals is of critical value for evidence-based policymaking, price-setting for surgical care and planning to strengthen the availability of high quality and cost-effective surgical care in district hospitals.

RESUMEN

Cyberbullying is a newer phenomenon which is becoming more prevalent among adolescent students with the use of information technology. The objective of the study was to determine the prevalence of being cyberbullied among late adolescent and to study the behavior and the attitude on cyberbullying. It was a cross-sectional study conducted on 254 school students (15-19 years). Data were collected by self-administered questionnaire, and results were analyzed using SPSS version 20. About 210 (82.7%) students were using any form of social networking site and out of which 22 (10.5%) students were cyberbullied. Among those who were cyberbullied, the majority (16 [72.7%]) had no opinion and more than half (15 [68.2%]) sought their friends' help. Cyberbullying is emerging as a newer social problem in our country, where students' lack of awareness and understanding of it results in underreporting of cyberbullying incidents.

RESUMEN

Understanding the burden and pattern of mental disorders as well as mapping the existing resources for delivery of mental health services in India, has been a felt need over decades. Recognizing this necessity, the Ministry of Health and Family Welfare, Government of India, commissioned the National Mental Health Survey (NMHS) in the year 2014-15. The NMHS aimed to estimate the prevalence and burden of mental health disorders in India and identify current treatment gaps, existing patterns of health-care seeking, service utilization patterns, along with an understanding of the impact and disability due to these disorders. This paper describes the design, steps and the methodology adopted for phase 1 of the NMHS conducted in India. The NMHS phase 1 covered a representative population of 39,532 from 12 states across 6 regions of India, namely, the states of Punjab and Uttar Pradesh (North); Tamil Nadu and Kerala (South); Jharkhand and West Bengal (East); Rajasthan and Gujarat (West); Madhya Pradesh and Chhattisgarh (Central) and Assam and Manipur (North East). The NMHS of India (2015-16) is a unique representative survey which adopted a uniform and standardized methodology which sought to overcome limitations of previous surveys. It employed a multi-stage, stratified, random cluster sampling technique, with random selection of clusters based on Probability Proportionate to Size. It was expected that the findings from the NMHS 2015-16 would reveal the burden of mental disorders, the magnitude of the treatment gap, existing challenges and prevailing barriers in the mental-health delivery systems in the country at a single point in time. It is hoped that the results of NMHS will provide the evidence to strengthen and implement mental health policies and programs in the near future and provide the rationale to enhance investment in mental health care in India. It is also hoped that the NMHS will provide a framework for conducting similar population based surveys on mental health and other public health problems in low and middle-income countries.

RESUMEN

OBJECTIVE: To assess the quality of life among thalassemic children and to find out association of quality of life (QOL) with the socio-demographic factors, and clinico-therapeutic profile. METHODS: This cross sectional descriptive epidemiological study was conducted from July 2011 through June 2012 on 365 admitted thalassemic patients of 5 to 12 y of age in the Burdwan Medical College and Hospital. Parents of the children were interviewed using Paediatric Quality of Life Inventory 4.0 Generic Core Scale. Statistically significant variables in bivariate analysis were considered for correlation matrix where independent variables were found inter related. So, partial correlation was done and statistically significant variables in partial correlation were considered for linear regression. RESULTS: The mean age of 365 thalassemic children was 8.3 ± 2.4 y. Multiple linear regressions predicted that only 70.5 % variation of total summary score depended on duration since splenectomy (31.2 % variation), last pre transfusion Hb level (20.7 %), family history of thalassemia (17.3 %) and frequency of blood transfusions (1.3 %). After splenectomy, thalassemic children could lead a better quality of life upto 5 y only. The betterment of the quality of life needs maintaining pre transfusion Hb level above 7 g/dl. Previous experience of the disease among the family members enriches the awareness among them and helps them to take correct decisions timely about the child and that leads to better QOL. CONCLUSIONS: More awareness regarding the maintenance of pre transfusion Hb level should be built up among parents and families where such disease has occurred for the first time.

RESUMEN

OBJECTIVES: The aim of this study was to examine different domains of quality of life (QOL) and their relationship to sociodemographic characteristics among older people in an urban slum in India. MATERIALS AND METHODS: A cross-sectional study was conducted (n = 120). Selected individuals were interviewed, and their QOL was assessed by the World Health Organization Quality of Life-BREF questionnaire. Statistical analysis was then performed. RESULTS: Of those included in the study population, 61.7% were men, all were Hindus, 46.7% were members of the general caste, 19.2% were illiterate, 35% were unemployed, and 72.5% lived with their joint family (i.e. extended family). Mean scores in each domain studied did not significantly differ between the sexes, age groups, castes, and family types. Subjects with more education, who were married, and with greater income had significantly better QOL scores. Mean scores were also better in certain domains among persons who had their own income and who resided with their children. CONCLUSION: Having low education, being single, lacking personal income, and not living with their children significantly reduced QOL in the elderly subjects. Attention should be given to these factors to help elderly individuals age in a healthy manner.

RESUMEN

BACKGROUND: Periodontal diseases, dental caries, malocclusion, and oral cancer are the most prevalent dental diseases affecting people in the Indian community. OBJECTIVE: The study was conducted to assess the awareness and practices on oral hygiene and its association with the sociodemographic factors among patients attending the general Outpatient Department (OPD). MATERIALS AND METHODS: A cross-sectional study was conducted among 224 patients attending the general OPD of the SSKM Hospital, Kolkata, India, from 1 April to 30 April, 2013. The study tool was a pre-designed and pre-tested semi-structured schedule. RESULTS: About 69.20% of the participants used a toothbrush with toothpaste as a method of cleaning their teeth; 35.71% brushed twice in a day; 33.03% brushed both in the morning and at bedtime; and 8.93% used mouthwash. About 40.62% visited the dentist during the last six months; among them 61.18% attended because of pain. Almost three-fourth of the participants knew that tooth decay and bad breath were the effects of not cleaning the teeth. It was known to 71.42, 63.39, 70.53, and 73.21% of the respondents, respectively, that excess sweet, cold drink, alcohol, and smoking/pan chewing were bad for dental health. Television was the source of knowledge to 57.14% of the participants and 35.71% acquired their knowledge from a dentist. Females, literates, urban residents, users of mouthwash, and regular visitors to the dentist had good oral hygiene practices. CONCLUSION: Oral health awareness and practices among the study population are poor and need to improve.

RESUMEN

BACKGROUND: Depression is a major public health threat that can affect anyone including health professionals and nursing students. OBJECTIVES AND METHODS: This analytical, cross-sectional study was conducted among 180 students of a nursing college to find out the burden of depression on them and possible contributing factors using the Beck Depression Inventory. RESULTS: 63.9% of the students were found to be depressed, the majority being mild in grade. First-year students were found to be significantly more affected (P=0.008). Binary logistic regression showed that familial disharmony, disinterest in the course and insecurity about future placement were statistically significant factors behind the development of depression. CONCLUSION: It is imperative that the psychological condition of nursing students be viewed as an important aspect to be considered, particularly within the Indian population and others in which there is a paucity of data.

RESUMEN

INTRODUCTION: The introduction of highly active antiretroviral therapy (HAART) for the treatment of human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) has led to the reduction of mortality and the improvement of the quality of life of people living with HIV/AIDS (PLWHA). The present study was conducted to determine the pattern of adherence to HAART among PLWHA, and to assess the factor(s) affecting nonadherence, if any. METHODS: This study was a hospital-based analytical, cross-sectional epidemiological study conducted between July and October 2011. A total of 370 adult HIV-positive patients registered in the Antiretroviral Therapy Centre of Burdwan Medical College and Hospital, West Bengal, India, were included. Nonadherence was defined as missing at least a single dose of medicine within the last four days. Data was analysed using the Statistical Package for the Social Sciences version 19.0 (IBM Corp, Armonk, NY, USA). RESULTS: A total of 87.6% of patients were found to be adherent to HAART. Principal causes of nonadherence were forgetting to take medicine (70.2%), being away from home (65.2%), and busyness with other things (64.7%). Multivariate logistic regression analysis revealed that nonadherence was significantly associated with a positive family history of HIV/AIDS (odds ratio [OR] 16; 95% confidence interval [CI] 2.2-114.3; p = 0.01), occurrence of side effects with HAART (OR 9.81; 95% CI 1.9-51.7; p = 0.01) and employment (OR 5.93; 95% CI 1.5-23.2; p = 0.01). CONCLUSION: Although overall adherence was high, the factors that affect nonadherence can be addressed with proper counselling and motivation of patients and their family members. Adherence to HAART could delay the progression of this lethal disease and minimise the risk of developing drug resistance.

RESUMEN

India adopted WHO's strategy of repeated rounds of mass drug administration (MDA) with diethylcarbamazine to eliminate lymphatic filariasis. The present study attempted to assess the coverage and awareness of and compliance with MDA for elimination of lymphatic filariasis in Burdwan district of India, following MDA round in July 2010. A cross-sectional study was conducted among the four randomly-selected clusters in the district of Burdwan, West Bengal, India, covering 603 individuals from 154 households, using a predesigned pretested schedule. The drug distribution coverage, compliance, and effective coverage were 48.76%, 70.07%, and 34.16% respectively. Only 41.4% of the study population was aware of the MDA activity. This evaluation study noted that MDA is restricted to tablet distribution only. There is an urgent need to improve compliance with drug intake through strengthening of the awareness programme involving both government health workers and community volunteers.

RESUMEN

PURPOSE: To investigate age-related effects on human corneal γ-glutamyltranspeptidase (GGT) (ectoenzyme important to maintaining corneal hydration and antioxidant potential via glutathione recapture). METHODS: Age-related differences between total, endothelial, and epithelial GGT activity and endothelial cell density were determined for corneas from 29 donors (mean age, 53 ± 17 years; age range, 13-83 years). GGT activity was determined using a standard colorimetric assay based on the transpeptidation reaction. Corneal GGT localization and expression was determined by immunohistochemistry. RESULTS: Total corneal, endothelial, and epithelial GGT activities in the young (<50 years) donor corneas were 37% (P = 0.02), 44% (P = 0.001), and 36% (P = 0.06) higher, respectively, than in the senior (≥50 years) corneas. The age-related rates of decline for GGT activity were 1.0 unit per year for total cornea, 0.4 to 0.5 unit per year for endothelium, and 0.3 to 0.4 unit per year for epithelium. Notably, endothelial cell density in the young corneas was 14% (P = 0.001) higher than in the senior corneas declining about 100 cells per square millimeter per decade (0.3% per year). GGT activity per 10 endothelial cells decreased at about 0.2 units per year and GGT activity per 10 endothelial cells in the young corneas was 41% higher (P = 0.01) than in the senior corneas. Fewer immunoreactive GGT-positive epithelial cells were detected in senior cornea. CONCLUSION: The age-related loss of human corneal GGT activity was associated with reductions in endothelial and epithelial GGT activity, being because of reduced number of GGT-positive endothelial and epithelial cells and reduced GGT activity per endothelial cell.

RESUMEN

A case of sporadic Burkitt lymphoma (sBL) presenting with jaw and lid involvement in a diabetic adult African American female and a review of adult orbital Burkitt lymphoma cases are presented. Lid edema, visual loss, ophthalmoparesis, proptosis, and sinusitis progressed over 4 weeks despite antibiotic and steroid treatment. Upper lid biopsy histopathological evaluation and immunophenotyping revealed a homogenous mass of atypical CD10 and CD20-negative B-cells and tingible body macrophages yielding a "starry sky" appearance. Cytogenetic analysis detected a minor variant c-MYC translocation, but no Epstein-Barr virus RNA. Detection of multiple lesions prompted a diagnosis of stage IV disease that totally regressed following radiation and chemotherapy. Review results of the six adult orbital sBL cases support a poor prognosis and a heightened suspicion of variant CD10, CD20 and BCL6 positive sBL in adults presenting with jaw pain and rapidly progressive orbital symptoms, particularly in female, African American, and diabetic patients.

RESUMEN

An 85-year-old male experienced a painless swelling along the left lateral orbit for one year. A computed tomography scan demonstrated a cystic mass in the orbit adjacent to the lacrimal gland. There was a concern for malignancy considering the large size and the patient's age, so the tumour was excised. Histopathology of the tumour showed nests with basaloid patterns, but a definitive diagnosis was not rendered. The uncertainty of tissue diagnosis coupled with the basaloid pattern, which carries a grim prognosis in some salivary gland tumours, led us to refer this case to an authority on lacrimal gland pathology, who suggested that this tumour be called a basal cell cystadenoma. To the best of our knowledge, a basal cell cystadenoma of the lacrimal gland has not been reported in the literature. We present histopathological features that distinguish this tumour from malignant tumours with a basaloid pattern. We also discuss the management differences associated with basaloid patterns in lacrimal tumours.

RESUMEN

BACKGROUND: Majority of the health problems affecting school children are preventable by promotion of hygienic practices through proper health education by the teachers, who are the first contacts. OBJECTIVES: The study was undertaken to find out the status of nutrition and personal hygiene among primary school children and their association with their varied morbidity profiles. MATERIALS AND METHODS: A descriptive, observational, cross-sectional study was conducted in a primary school situated in the largest slum of Kolkata. RESULTS: The participants included 103 boys and 81 girls, with a mean age of 6.2 years. The mean personal hygiene score of the girls (4.15 ± 0.98) was significantly higher than that of boys (3.2 ± 1.4) [P<0.05]. Most of the boys (54.37%) and girls (74.07%) were normally nourished as per the CDC growth chart. Over 70% of the children were suffering from one or more morbidities, the most common morbidity in both the sexes being pallor, followed by worm infestation. Personal hygiene scores were significantly higher (P<0.05) among those children who were normally nourished as well as those who did not suffer from any morbidity in the last 15 days. CONCLUSIONS: Care should be taken to improve the pitiable state of personal hygiene and poor sanitary practices of these school children through coordinated and concerted health education measures by teachers as well as parents.

RESUMEN

PURPOSE: The viability and functions of the corneal epithelium are dependent in large measure on the active uptake of nutrients, growth factors, and amino acids from stroma and tear. The present study presents the cellular distribution(s) of glutamate, the Na(+)-dependent glutamate/aspartate transporters (excitatory amino acid transporters; EAAT1-5), Na(+)-independent glutamate/cystine exchanger (Xc(-) antiporter) subunits (xCT light chain and 4F2hc heavy chain), glutamine synthetase (GS), and gamma-glutamyltranspeptidase (GGT) in human corneal epithelium. METHODS: Glutamate, EAAT1-5, xCT/4F2hc, GS, and GGT immunoreactive proteins were detected by immunofluorescence microscopy. Human corneal GGT activity was quantified using a standard colorimetric assay. RESULTS: Glutamate, EAAT3>2>1, xCT/4F2hc, and GGT proteins were detected in the columnar and wing cells. Glutamate was reduced or absent in the EAAT negative, Xc(-) antiporter, and GS positive outer wing cell and flat superficial epithelial cell layers. All EAATs (EAAT3>4/5>1/2), xCT/4F2hc, GS, and GGT were detected in flat superficial epithelial cell layer. CONCLUSIONS: The localization of glutamate, multiple EAATs, Xc(-) antiporter proteins, and GGT to columnar and superficial epithelial cell layers suggests uptake of glutamate and cystine from the stroma and tear and supports their importance in regulation of glutamate/cystine and glutathione (GSH; a tripeptide of glutamate, cystine, and glycine) in the human cornea epithelium. In addition, the low glutamate levels in outer wing and flat superficial epithelial cells positive for Xc(-) antiporter and GS are consistent with exchange of glutamate by Xc(-) antiporter for extracellular cystine utilized in GSH synthesis and support coupling of ammonia detoxification with glutamate degradation by GS.

RESUMEN

A case of orbital metastasis of cervical keratinizing squamous cell carcinoma is presented. The patient, in remission from primary cervical and ovarian cancers, presented with complaints of left eye ptosis and pain. Examination revealed the presence of a moderately tender mass along the left supra-temporal orbital rim and downward displacement of the left globe. Computed tomography revealed a poorly circumscribed mass with superior lateral wall bone loss. Excised tissue contained invasive, poorly differentiated nests of pan keratin and epithelial membrane antigen-positive squamous cells with numerous pleomorphic multinucleated giant cells. Multiple treatment regimes were unsuccessful, and the patient expired due to disease complications after 3 months.

RESUMEN

The uveitogenic bacterial cell wall component muramyl dipeptide (MDP) is apoptogenic in rabbit kidney cells. The purpose of this investigation was to assess the cytotoxic activity of MDP and staurosporine (STSP; induces cultured corneal and lens cells apoptosis) in rabbit ciliary body tissue. Anterior uveitis was determined by clinical symptoms and increased aqueous humor (AH) protein. Ciliary body tissue was assessed for histological changes, caspase-3 activity, dye uptake, distribution of immunoreactive caspase-3 and DNA ladders at 4 and 6 hours postinjection. Increases in caspase-3 activity, APOPercentage dye uptake, and localization of immunoreactive caspase-3 in ciliary epithelial cells were associated with ciliary cysts of detached nonpigmented epithelial (NPE) cells, as well as apoptotic and necrotic DNA ladders in ciliary body tissues from eyes injected with MDP and/or STSP. The results suggest that intracameral injection of the bacterial components MDP and STSP can induce acute endophthalmic changes in uveal tissue including formation of ciliary body, NPE and pigmented epithelial (PE) cell apoptosis, and ciliary body tissue necrosis.

RESUMEN

Process indicators have been recommended for monitoring the availability and use of emergency obstetric care (EmOC) services. A health facility-based study was carried out in 2002 in four districts of West Bengal, India, to analyze these process indicators. Relevant records and registers for 2001 of all studied facilities in the districts were reviewed to collect data using a pre-designed schedule. The numbers of basic and comprehensive EmOC facilities were inadequate in all the four districts compared to the minimum acceptable level. Overall, 26.2% of estimated annual births took place in the EmOC facilities (ranged from 16.2% to 45.8% in 4 districts) against the required minimum of 15%. The rate of caesarean section calculated for all expected births in the population varied from 3.5% to 4.4% in the four districts with an overall rate of 4%, which is less than the minimum target of 5%. Only 29.9% of the estimated number of complications (which is 15% of all births) was managed in the EmOC facilities. The combined case-fatality rate in the basic/comprehensive EmOC facilities was 1.7%. Major obstetric complications contributed to 85.7% of maternal deaths, and pre-eclampsia/eclampsia was the most common cause. It can be concluded that all the process indicators, except proportion of deliveries in the EmOC facilities, were below the acceptable level. Certain priority measures, such as making facilities fully functional, effective referral and monitoring system, skill-based training, etc., are to be emphasized to improve the situation.
