RESUMEN
Background: Study of first episode psychosis (FEP), an episode of psychotic nature, which manifests for the first time in an individual in the longitudinal continuum of his/her illness, has been a matter of research interest in recent years, as this may give more insight to the overall phenomenology and course of psychotic illnesses. Methods: A study was undertaken to evaluate course and outcome of first episode psychosis. A total of 100 consecutive inpatients were selected for the study. Informed consent was obtained. Structured Proforma was used for recording psychosocial profiles and relevant medical history. Brief Psychiatric Rating Scale (BPRS) was given to assess the severity of psychopathology; Positive and Negative Symptom Scale (PANSS) to assess the severity of psychosis; Becks Suicidal Ideation Scale (BSI) to assess the extent of suicidality and Global Assessment of Functioning (GAF) to assess global functioning of the individual. The assessment was done at baseline, at six months, and at one year. Results: First episode psychosis constituted around a tenth of the caseload. It commonly affected people in the third decade of life. There was an improvement in 92% of the cases over a year of study. Schizophrenia constituted the majority of first episode psychosis. The history of smoking was relatively higher in acute and transient psychotic disorders. Age inversely correlated with the severity of psychopathology. There was no difference in improvement in psychopathology over time in patients of schizophrenia and related disorder vis--vis other psychotic disorders. Conclusion: Our study did not find any significantly varied sociodemographic factors in the course and outcome of the illness. It also refuted the schism between various types of psychosis based on the current classificatory system. It draws our attention toward the unitary concept of psychosis and is a call to re-think our strategies in the management of psychosis.
RESUMEN
Background: The Indian Armed Forces, on entry, vaccinates all cadets and recruits with varicella vaccine for the prevention of varicella. This health technology assessment (HTA) report puts forth evidence for HTA of varicella vaccination in the Armed Forces in various domains namely clinical, societal, ethical, economic, and legal. Methods: The policy question under each domain has been developed according to best-practice methods for HTA. The costs included were hospitalization cost due to varicella infection; training lost cost; the varicella vaccine cost; cost of the side effects of vaccine; and the outbreak investigation cost. The incremental cost-effectiveness ratio (ICER) for varicella cases averted and man-days saved, and quality-adjusted life years (QALYs) gained due to varicella vaccination strategy were calculated. Results: Evidence suggests a reduction of 81% in hospitalization rates with 19392 man-days saved per 1 lakh population due to varicella vaccination strategy. The ICER for varicella cases averted is estimated to be Rs 56732/- per case averted and Rs 5687/- per man-day saved. QALYs gained due to two-dose varicella vaccination strategy is estimated to be 1152 per 1 lakh population with cost per QALY gained Rs 95735/-. Conclusion: The study showed a large reduction in hospitalizations and consequently man-days lost after the introduction of the vaccination strategy. The QALYs was another aspect of importance brought out by this study. Thus, a two-dose vaccination strategy for varicella-zoster virus (VZV) for the Armed Forces trainees is a cost-effective policy.
RESUMEN
BACKGROUND: The tobacco epidemic is one of the biggest public health threats the world has ever faced. World Health Organization has estimated that tobacco use (smoking and smokeless) is currently responsible for the death of about 7 million people across the world each year. The objective of the study was not only to find the effect of group intervention on tobacco cessation but also to describe certain epidemiological factors associated with tobacco cessation and make suitable recommendations to tackle this epidemic. METHODS: A randomized controlled trial was carried out among male employees who were tobacco users in health-care setting in Western Maharashtra. In the study, 60 subjects each in intervention and control arm were taken. Pretested validated questionnaires were used for the study. The intervention comprised of two sessions delivered 5 weeks apart. Control arm received self-help material (Booklet) immediately after baseline data collection. The outcomes were measured using structured interview schedule. The data were analyzed using SPSS, version 20. RESULTS: Overall, 13.3% of the study subjects had quit tobacco use post intervention. In the intervention group 21.7% of the participants had quit tobacco since past one month and 5% in the control group (relative risk (RR) = 4.33). Low to moderate nicotine dependence (p = 0.023, RR = 6.46) and stage of contemplation (p = 0.018) were found to be important predictors of abstinence. CONCLUSION: Community-based group intervention for tobacco cessation is the way forward to tackle the tobacco epidemic.
RESUMEN
BACKGROUND: Evidence-based policy decision-making is introduction of newer technology that it is 'not inferior' to existing technology. Multiple randomised clinical trials (RCTs) on tuberculosis (TB) treatment have shown mixture of favourable, unfavourable and non-significant changes in outcomes with the use of fixed-dose combination (FDC) regimens. The aim of this study was to assess clinical effectiveness of FDC regimen as compared to the use of separate drugs in anti-TB treatment. METHODS: Systematic literature search was carried out. RCTs with newly diagnosed smear-positive pulmonary TB cases were included. Defined outcomes were smear conversion, relapse, adverse reactions and patient compliance. RESULTS: Initial search revealed 457 articles, out of which 7 were included for meta-analysis. Pooled risk ratio for smear conversion rate at the end of intensive phase was 1.01 (95% confidence interval [CI], 0.99-1.03; p = 0.40). Similarly, smear conversion rate at the end of treatment showed no significant difference (relative risk (RR) = 1.01; 95% CI, 0.99-1.02; p = 0.45). Pooled risk ratio for combined smear conversion rates was 1.01 (95% CI, 0.99-1.02). However, relapse rates showed marginally higher trend with FDC regimens (RR, 1.56; 95% CI, 0.95-2.56; p = 0.49). Pooled analysis for adverse events showed no significant difference (RR = 0.98; 95% CI, 0.86-1.11; p = 0.70). Analysis of patient compliance showed marginal increase among FDC group (RR = 1.02; 95% CI, 0.96-1.09; p = 0.47)). CONCLUSION: Fixed-dose combination (FDC) formulations are not inferior in treatment outcomes. It may also ease programme managers and patients by improving compliance. However, increase in relapse rates needs further evaluation through large multicentric studies before implementing policy change in the national programme.
RESUMEN
BACKGROUND: The World Health Organization on 11 March 2020, declared COVID-19 as a pandemic. India initiated social distancing measures to combat the epidemic of COVID-19. The course of the epidemic of COVID-19 for India was predicted using stochastic probability-based mathematical modeling. METHODS: Data synthesis for the top few countries affected was studied for various factors affecting the epidemic. For projections of infected cases for India, the modified susceptible-exposed-infectious-removed/recovered framework modified for the effect of social distancing (Rho) was used. Simulation was carried out for 10,000 runs using Python. Projections for infected cases and hospitalization requirement were estimated. RESULTS: The epidemic curve will peak in the third week of June in India with 17,525,869 and 2,153,200 infected people with reproduction number of 1.8 and Rho of 0.7 and 0.6, respectively. Compared with the baseline scenario of no social distancing, for transmissibility with R0 = 1.8, the reduction in infections due to social distancing measure is 78% (Rho = 0.7) and 97% (Rho = 0.6). Similarly for R0 = 2.2 and 2.4, the reduction in infected numbers slightly lowers to 62% and 66% with Rho = 0.7 and 92% and 75% with Rho = 0.6, respectively. With R0 = 1.8 and Rho = 0.6, the Intensive Care Unit (ICU) bed requirement is 107,660, whereas if transmissibility is high, the ICU bed requirement would increase to 1,994,682. CONCLUSIONS: The social distancing measures seem to have been working for India in absence of treatment in sight for COVID-19. Although with the government's response strategy of social distancing, the peak of the epidemic is extended giving more months for preparedness to the country; however, the sustainability of these measures is uncertain.
RESUMEN
BACKGROUND: Increased pulmonary ventilation helps lowlanders and natives to maintain arterial oxygenation at high altitudes. Natives of Ladakh have been shown to have similar ventilatory parameters as Tibetans at 3300 m. But there is limited literature comparing these parameters in Ladakhi natives with acclimatized lowland sojourners. METHODS: End-tidal carbon dioxide partial pressure (EtCO2), blood oxygen saturation (SpO2) and hemoglobin concentration (Hb) were measured in 276 participants, 126 native highlanders (NHL - 40 females, 86 males) and 150 acclimatized lowlanders (ALL - 60 females, 90 males). RESULTS: EtCO2 was greater in the NHL compared to the ALL, (33.8 ± 3.3 vs 31 ± 2.5 mmHg) although SpO2 was lower (90.9 ± 2.4 vs 91.7 ± 2.3%). When grouped by sex, NHL males had significantly greater EtCO2 than NHL females, ALL males and ALL females. Hb and calculated arterial oxygen content was similar in Ladakhis and acclimatized lowlanders, although greater in males compared to females. Systemic blood pressure, heart rate and the proportion of hypertensives was significantly greater in the ALL. CONCLUSION: Native Ladakhis, have a significantly greater resting EtCO2 (especially in males) and lower SpO2 than acclimatized lowlanders. Blood Hb concentration and oxygen content is, however, similar in natives and acclimatized lowlanders of the same sex.
RESUMEN
BACKGROUND: The World Health Organization (WHO) in 2013 has revised its guidelines on antiretroviral therapy (ART) treatment for human immunodeficiency virus (HIV)-positive adults and further updated it in 2016. Based on the WHO recommendations, in May 2017, National AIDS Control Organisation, India recommended initiation of ART treatment for all people living with HIV, regardless of CD4 count, clinical stage, age, or population. This systematic review aims to assess the clinical effectiveness and cost implication of the new guidelines for India. METHODS: A systematic and comprehensive literature search on PubMed, OvidSP, Cochrane Library, and Google Scholar was carried out. Studies reporting either acquired immunodeficiency syndrome (AIDS) or mortality or both as outcome variables were selected. A meta-analysis of the available studies was carried out. The risk ratio was calculated to assess the reduction in AIDS or mortality or both. Cost-effectiveness analysis using health technology principles evaluating the lives saved in terms of incremental cost-effectiveness ratio and cost per quality-adjusted life years gained was carried out. RESULTS: Nine eligible studies were included for the meta-analysis. For India, the pooled relative risk of AIDS or mortality or both being 0.84 (95% confidence interval [CI], 0.76-0.92) and 0.78 (95% CI, 0.68-0.89) for ART initiation at CD4 count of ≤350 vs CD4 count of ≤500 and at CD4 count of ≤500 vs CD4 count > 500 cells/mm3, respectively. The incremental cost for per additional life saved is US$ 2592 and US$ 2357 for ART initiation at ≤500 and > 500 CD4 count, respectively. CONCLUSION: The adoption of the new WHO guidelines is beneficial with substantial reduction in AIDS or mortality or both. This study suggests that adopting new WHO guidelines is cost-effective for India.
RESUMEN
BACKGROUND: Competency based medical education (CBME) is outcome based teaching methodology where a student learns a set of measurable competencies for early clinical exposure. Inspite of ample resources on CBME, there are limited studies on its implementation. This study will try to demonstrate improvement in the performance of students using CBME as a teaching tool over the traditional structured method (TS). METHODS: Forty student volunteers were chosen and divided into two groups. The crossover design exposed the group of students to CBME and TS spread over two periods with a wash out period in between. The intervention group was exposed to selected list of competencies in living Anatomy with feedbacks and formative assessments. The summative assessments were held at the end of each period. RESULTS: The mean scores of CBME and TS in group 1 is 130.625 and 113.65 while in group 2 is 139.425 and 112.075 respectively. The treatment and period effect is significant. Estimate of treatment effect is 22.1625. The average improvement in treatment scores is by 11%. Two tailed paired sample T test reveals significant improvement in the scores post intervention. CONCLUSION: CBME method produces better performance of the students in the competencies of living anatomy.
RESUMEN
BACKGROUND: As HIV steps into the third decade, there are more number of patients living on lifelong (antiretroviral therapy) ART and facing the threat of drug resistance with subsequent treatment failure. The aim of this study was to determine predictors of first-line ART failure with the objectives to estimate the burden of 2nd line ART. METHODS: A retrospective 5-year cohort of HIV patients who were initiated on first line ART in 2008-09 was studied. Patients were followed from the time of ART initiation. Kaplan-Meier methods and Cox proportional hazards regression models were used to estimate probabilities and predictors of first line ART failure. RESULTS: Of the total of 195 patients initiated on first line ART, 15 patients were switched to second line ART yielding 7.69% failure rate. During the 7178 person-years of follow-up, the incidence of first line ART failure was 2.09 per 1000 person-years. The Kaplan-Meier survival analysis gave a mean survival time of 55.6 months. BMI, CD4 count at ART initiation and presence of opportunistic infections were significant predictors of first line ART failure. The burden of second line ART patients by the end of 5 years of first line ART is expected to be 151 patients. CONCLUSION: Though the first line ART failure is quite low in this study, we still need to be vigilant for lower BMI, low baseline CD4 count and occurrence of opportunistic infections to efficiently manage failures on first line ART.
RESUMEN
BACKGROUND: Resistance to antimicrobial agents is emerging in wide variety of nosocomial and community acquired pathogens. Widespread and often inappropriate use of broad spectrum antimicrobial agents is recognized as a significant contributing factor to the development and spread of bacterial resistance. This study was conducted to gain insight into the prevalent antimicrobial prescribing practices, and antimicrobial resistance pattern in nosocomial pathogens at a tertiary care hospital in Pune, India. METHODS: Series of one day cross sectional point prevalence surveys were carried out on four days between March and August 2014. All eligible in patients were included in the study. A structured data entry form was used to collect the data for each patient. Relevant samples were collected for microbiological examination from all the clinically identified hospital acquired infection cases. RESULTS: 41.73% of the eligible patients (95% CI: 39.52-43.97) had been prescribed at least one antimicrobial during their stay in the hospital. Beta-lactams (38%) were the most prescribed antimicrobials, followed by Protein synthesis inhibitors (24%). Majority of the organisms isolated from Hospital acquired infection (HAI cases) were found to be resistant to the commonly used antimicrobials viz: Cefotaxime, Ceftriaxone, Amikacin, Gentamicin and Monobactams. CONCLUSION: There is need to have regular antimicrobial susceptibility surveillance and dissemination of this information to the clinicians. In addition, emphasis on the rational use of antimicrobials, antimicrobial rotation and strict adherence to the standard treatment guidelines is very essential.
RESUMEN
BACKGROUND: Use of contraception is influenced by many processes most by the women's empowerment. Women's decision making power and their autonomy within the household is the most important factor affecting contraceptive use. This paper aims to analyze the relationship between these two indicators of women's empowerment and the use of contraception. METHODS: This cross sectional study was conducted by personally interviewing 385 currently married women selected by systematic sampling on a pretested and validated questionnaire. Two indices, women's decision-making power index and women's autonomy index, were constructed and association with contraception use analyzed. RESULTS & CONCLUSION: The study gives the evidence that decision making power is low in the respondents with 48.2% (95% CI 43.34, 53.31) of them having low level of power, while 27.6% (95% CI 23.24, 32.16) have medium level and 3.6% (95% CI 2.08, 5.88) having high level of power. 22.4% (95% CI 18.39, 26.70) of women do not have any autonomy as against 43.9% (95% CI 38.99, 48.89) with low level, 25% (95% CI 20.80, 29.44) with medium autonomy and 8.7% (95% CI 6.29, 11.98) scoring above 7 (high level of autonomy). In the study population it was found that 273 (70.7%, 95% CI 66.2, 75.28) of the respondents were using contraceptives. Women's autonomy, years of marriage and number of children were significant variables.
RESUMEN
BACKGROUND: The progressive decline in the CD4 count in HIV patients leads to a more general decline in immune functioning. The study has been carried out to determine the decline in CD4 count in HIV patients. METHODS: The study was conducted in a medical college hospital at Maharashtra. The information on baseline CD4 count was gathered from positive patient records registered in the central disease registry. The baseline CD4 count was the first count of CD4 obtained when the patient is diagnosed as HIV positive and further two subsequent readings. The time from baseline (t1) till the last CD4 count (t2) was divided into the different quartiles and the median decline in CD4 count in each quartile was determined. As the time between the two CD4 count measurements was not uniform the rate of change in CD4 was measured with respect to time as [X (t2) - X (t1)/(t2 - t1)]. Correlation was assessed using correlation coefficient. RESULTS: As the CD4 counts were following skewed distribution, the normality was achieved by cuberoot transformation. The overall rate of decline in CD4 count was estimated to be 35 cells/µL per year with 95% confidence interval (CI) as (17.01, 85.04). The correlation coefficient between decline in CD4 and the initial CD4 count in the four time quartiles was (r = -0.51; p = 0.001, r = -0.79; p = 0.000, r = -0.48; p = 0.015 and r = -0.80; p = 0.000) respectively. The median decline in the CD4 count in 0-6 months was 3 cells/µL, in (6-11) months was approximately 26 cells/µL, in (11-21.5) months was 30 cells/µL and in more than 21.5 months the median decline was 52 cells/µL. CONCLUSIONS: There was a progressive decline in the CD4 count following HIV infection. An understanding of the influence of decline in CD4 count in HIV patients not on ART is important for clinical management of HIV disease.
RESUMEN
BACKGROUND: Adolescence is a period when the individual is vulnerable and exposure to sexually implicit/explicit programs on television and internet can influence their sexual behaviour and make them more permissive towards premarital sex, which is known to influence their academic performance. This can be modified by parental discussion on these matters with their children. There have been only few studies from India that have explored such issues therefore this study aimed to explore the impact of television, internet and parental discussion on sexual activity and academic performance. METHODS: This study was conducted in two co-education schools using a self reporting questionnaire administered to students of class IX-XII. This study evaluated the relation of academic performance, exposure to media such as television & internet to sexual activity & academic performance of the students and the role of parental discussion on these. RESULTS: The study sample size was 586. There is no significant association between the number of hours of watching television per day and academic performance as measured by marks in examinations. Significant positive association was found among boys between sexual contact and average score in academics & unsupervised use of internet. In both genders a significant positive association was found between those watching English serials, movies and increased chances of indulging in sexual activity while a negative relation with those watching Cartoons. There is no significant difference in occurrence of sexual contact in those who discussed sexual matters with parents and those who did not. CONCLUSION: This being first of it's kind of study from India and a cross sectional study, further prospective and detailed studies are warranted to delineate the interaction of media, parental discussion, academic performance and sexual activity.
RESUMEN
BACKGROUND: High blood pressure in childhood is a major risk factor for heart disease and stroke in adulthood. There is enough evidence to suggest that the roots of essential hypertension in adults extend into childhood. There is a paucity of literature on the blood pressure measurements amongst children. This study was done to study blood pressure profile of school children in rural area of Maharashtra. AIM & OBJECTIVES: This cross sectional study was carried out to determine the prevalence of hypertension in children 6-15 years and to study the association between selected variables and blood pressure. MATERIAL & METHODS: This study was done using a predesigned questionnaire and making measurements of height, BMI and Blood pressure using standardized physical instruments following standard guidelines. The data was collected and analyzed using appropriate statistical tests. RESULTS: The prevalence of hypertension in the study was found to be 4.4% with 3.5% in females and 5.1% in males. CONCLUSION: In the study, hypertension in students was found to be significantly associated with higher BMI and with family history of hypertension. Age, height and BMI were found to correlate positively with Blood pressure levels in this study.
RESUMEN
Introduction: Demographic indices known as the age-heaping indexes were used to explore the patterns of age misreporting in a multicentric survey. Methods: The data of 3252 individuals were analyzed, and measurement of errors in age for the sampled data has been evaluated by Whipple's Index (WI), Myer's Blended Index, and United Nations Age-Sex Accuracy Score which comprises Sex Ratio Score, Male Age Ratio Score (ARS), and Female ARS. Results: Out of total 3252 participants, 828 (25.5%) were female. The mean statistical division age of our population was 34 (8.5) years and ranged from 15 to 65 years. The percentage of female ages ending with digits 0 or 5 is 23.55% and percentage of male ages ending with digits 0 or 5 is 23.28%. The calculated WI was 117.75 and 116.34 for males and females, respectively. The calculated Myer's Index for females and males is 10.53 and 25, respectively. Conclusion: The study provides evidence that probably age-heaping bias is less of problem in the conducted study.
RESUMEN
BACKGROUND: The limitations of the conventional methods for diagnosing tuberculosis (TB) have spurred multi-faceted research activities throughout the world. This study aims to explore the levels of adenosine deaminase (ADA) and interleukins in pleural effusion of tuberculous, malignant, and miscellaneous origin for differential diagnosis of tubercular and non-tubercular effusion. METHOD: Adenosine deaminase was estimated by kinetic method employing xanthine oxidase while interleukins were measured using commercially available ELISA kits in pleural fluids of tubercular and non-tubercular origin. RESULTS: Pleural fluids INF-γ, sIL-2R, TNF-α and ADA were significantly higher in TB group (n = 48) as compared to the non-TB group (n = 33) (mean ± SD: INF-γ; 1,958.7 ± 896.5 pg/mL vs 356.9 ± 733.6 pg/mL, sIL-2R; 6,101 ± 1,753.8 pg/mL vs 3,166 ± 2,611.1 ± pg/mL, TNF-α; 195.5 ± 292.1 pg/mL vs 59.7 ± 128.9 pg/mL, ADA; 123.6 ± 81.8 IU/L vs 48 ± 48.5 IU/L, P < 0.01). CONCLUSION: INF-(is more sensitive and specific than ADA for the diagnosis of TB and should be added to the armamentarium of the diagnostic workup of pleural fluids for timely and accurate diagnosis of TB and differentiation of tubercular pleural effusion from non-tubercular effusion.
RESUMEN
BACKGROUND: There are few epidemiological studies on prevalence of hypertension and its determinants in rural population. This cross sectional study was done to determine the same in a rural community. METHODS: A random sample of 406 people (218 men and 188 women) of 30 years and above was selected from a rural area. The pre tested proforma was used to collect the data by trained doctors. RESULT: Prevalence of smoking and tobacco use was 16%, alcohol intake 9.4 %, daily salt intake (≥ 5 gram) 34.2%, daily saturated fat intake (≥ 10 % of daily energy intake) 47 .0 % and physical inactivity (work and leisure) as 18.5%. Body Mass Index (BMI) was ≥ 25 in 18 % and ≥ 30 in 3.2% men and women. Prevalence of truncal obesity (Waist Hip Ratio: men ≥ 0.9; women ≥ 0.8) was 8.5% with higher incidence in men. Prevalence of abdominal obesity (men ≥ 102 cms; women ≥ 88 cms) was found in 15.7 % with higher incidence in men. Differences in prevalence of risk factors between men and women were statistically significant in case of smoking, alcohol consumption and abdominal obesity. 18.5% men and women were suffering from systolic hypertension (≥ 140 mg Hg) and 15 % from diastolic hypertension (≥ 90 mg Hg). Prevalence of risk factors for hypertension was significantly more among subjects suffering from systolic and diastolic hypertension than normotensive subjects. CONCLUSION: Prevalence of systolic hypertension in rural community was 18.5 % and of diastolic hypertension 15% with higher prevalence in the age group of 60 years and above, in case of men and women. There was a significant linear trend in prevalence of systolic hypertension with respect to age group in men whereas it was not significant in case of women.
RESUMEN
BACKGROUND: Male Preference is well known phenomena world wide from ancient ages. A descriptive study was carried out to assess the attitude of women towards birth of son, use of contraception methods and sex determination methods in rural village Kasurdi in Pune district. METHODS: Univariate analysis was carried out by considering each factor determining sex preference separately as well as using a Logistic Regression Model. Adequacy of fit of the model has also been tested. RESULT AND CONCLUSION: Out of 110 respondents interviewed, 62.7% felt that male child is necessary in the family. Univariate analysis revealed that sex of first child, concern undergone for second pregnancy with regards to sex of the child, number of children in family and type of family were significant factors contributing to the son preference. The analysis under the logistic regression model revealed that sex of the first child and concern undergone in second pregnancy with respect to the sex of the second child are the most dominating and significant factors in the causation of son preference. The difference between family sizes when compared with the sex of first child was statistically significant signifying that if the first child is a male then it hardly matters whether the second child is male or female, but if the sex of first child is female then the families land up with bigger family size. On an average most of the respondents favour two children with an equal share of male and female children.
RESUMEN
A cross-sectional health examination survey was carried out among a random sample of 406 people of 30 years and above from a rural community to investigate the prevalence of coronary heart disease risk factors. Prevalence of smoking and tobacco use was 16%, alcohol intake 9.4 %, daily Salt intake (> or = 5 gram) 34.2%, daily saturated fat intake ( > or =10 % of daily energy intake) 47.0 % and physical inactivity 18.5 %. BMI was > or =25 Kg /m(2) in 18 percent and it was > or =30 Kg / m(2) in 3.2 percent population. Truncal obesity (WHR: men> 0.9; women > 0.8) was found 18.5 percent more in case of males (20.7). Abdominal obesity(men > or =102; women > or = 88)was found 15.7 percent more in case of males (20.6).18.5 percent population was found suffering from systolic hypertension> or =140 mm Hg )and 15 percent from diastolic hypertension(> or =90 mm Hg). Awareness of CHD risk factors was present in 30.0 percent population. Differences in prevalence of riskfactor in male and female were found statistically significant in case of smoking, alcohol consumption and abdominal obesity. The present study shows that prevalence of CHD risk factors increases significantly in men and women having BMI equal or more than 25 Kg /m(2) so this cutoff, should be used to determine obesity in Indian population.

BACKGROUND: This study presents data on the prevalence rate of infectious markers among voluntary and replacement donors in the blood transfusion service in Armed Forces from 2000 to 2004. METHODS: 39,646 units of blood were collected from donors during the period from 2000 to 2004. All the samples were screened for hepatitis B surface antigen (HBsAg), human immunodeficiency virus (HIV) 1&2, hepatitis C virus (HCV), and by venereal disease research laboratory test (VDRL). RESULTS: 24,527 (61.9%) were voluntary donations and 15,119 (38.1%) replacement donations. Prevalence of HBsAg had decreased, amongst voluntary donors from 1.67% to 0.77% but the positivity rate has not showed significant change. Seropositivity of HIV had decreased both in voluntary and replacement donors to 0.22% and 0.86% respectively. The seropositivity for anti-HCV showed steady decrease amongst voluntary donors from 0.46% to 0.20% in 2004, but in replacement donors, there was an increase in reactivity rate from 0.43% to 0.65%. CONCLUSION: The increased seropositivity for HCV, HIV and HBsAg could be decreased by introduction of nucleic acid amplification testing (NAT) in minipools for HCV and HIV and introduction of anti-HBcAg (IgM) for hepatitis B virus (HBV) infection. But this may not be possible in near future in developing countries due to financial constraints. At present implementation of strict donor criteria and with use of sensitive laboratory screening tests it is possible to reduce the incidence of transfusion transmitted infections (TTI) in Indian scenario.
