Hypertension care cascade in an urban resettlement colony and slum in Delhi, India: a cross-sectional survey.

BACKGROUND: Hypertension care cascade in resource-limited settings is compromised with a majority of patients with hypertension remaining undiagnosed, untreated, non-adherent, and poorly controlled at every stage. However, there is paucity of information on care and management of hypertensive patients in community-based settings of low-income urban neighbourhoods in India. METHODS: This was a community-based cross-sectional study conducted in an urban resettlement colony and slum area in the Northeast District of Delhi. The adult population was screened for hypertension using standardized methods, and adherence to medications was assessed using the Morisky Green Levine scale. Binary logistic regression analysis was conducted to ascertain the sociodemographic predictors of the outcome (presence of hypertension, adherence to antihypertensive medication, blood pressure control). A p-value < 0.05 was considered statistically significant. RESULTS: We included 8850 adult participants including 5295 females and 3555 males in this study. Nearly 29% of the participants were hypertensive, of which 61.77% were newly diagnosed cases. Furthermore, nearly 81% of the previously diagnosed cases had been initiated on antihypertensive medication, of which 57.54% were adherent to their medications while 36.12% attained controlled blood pressure levels. The odds of having hypertension were significantly higher among males (AOR = 1.87, 95% CI: 1.63 to 2.15), age ≥ 60 years (AOR = 9.15, 95% CI: 7.82 to 10.70), high waist circumference (AOR = 2.24, 95% CI: 1.86 to 2.70) and Body Mass Index of ≥ 25.00 (AOR = 2.55, 95% CI: 2.00 to 3.26). Furthermore, on adjusted analysis, patients of hypertension having diabetes (DM) comorbidity had significantly higher odds of being adherent to anti-hypertensive medications (AOR = 1.81, 95% CI: 1.31 to 2.51) compared to those without DM comorbidity, while tobacco users had significantly lower odds of being adherent to antihypertensive medication (AOR = 0.50, 95% CI: 0.31 to 0.82). CONCLUSIONS: Hypertension care cascade in urban slum-resettlement colony setting revealed a high burden of undiagnosed hypertension, low rates of medication adherence, and poor blood pressure control. Strengthening community screening and primary care continuum of care is necessary to improve the hypertension care cascade from early diagnosis to effective management with optimal health outcomes to reduce patient complications and increase longevity.

Clinical presentation and mortality risk factors for COVID-19 among diabetic patients in a tertiary care center in South India.

BACKGROUND: Non-communicable diseases (NCD) like hypertension, diabetes, cardiovascular and cerebrovascular diseases are the most common comorbidities among COVID-19 patients. The clinical presentation and mortality pattern of COVID-19 are different for patients with comorbidities and without comorbidities. OBJECTIVE: To determine the clinical presentation of COVID-19 and risk factors for COVID-19 mortality among diabetic patients in a tertiary care hospital in South India. METHODS: A record-based cross-sectional study was conducted by reviewing the case records of COVID-19 patients admitted for treatment from June 2020 to September 2020 in a tertiary care centre in South India. Potential risk factors for COVID-19 mortality were analysed using univariate binomial logistic regression, generalized linear models (GLM) with the Poisson distribution. Survival curves were made using the Kaplan-Meier method. RESULTS: Out of 200 COVID-19 patients with diabetes with a mean (SD) age of 56.1 (11.8) years, 61% were men. The median survival time was slightly lesser in male COVID-19 patients (15 days) as compared to female patients (16 days). The risk of mortality among COVID-19 patients with diabetes is increased for patients who presented with breathlessness (aRR = 4.5 (95% CI: 2.3-8.8)), had positive history of smoking (aRR = 1.9 (95% CI: 1.1-3.8)), who had CKD (aRR = 1.8 (95% CI: 1.1-2.8)) and who had cardiac illness (aRR = 1.6 (95% CI: 0.9-2.7)). CONCLUSION: Diabetes patients with COVID-19 need to be given additional care and monitoring especially if they present with breathlessness, positive history of smoking, cardiac illness and, CKD. Public health campaigns and health education activities to control smoking is needed to reduce the COVID-19 mortality in diabetes patients.

Perceptions of Good Health and Impact of COVID-19 Among Adolescents in a Low-Income Urban Agglomerate in Delhi, India: A Qualitative Study.

Adolescents constitute 16% of the global population and are susceptible to adverse health and illness from substance abuse, unhealthy diet, physical inactivity, and high-risk sexual behaviors. We conducted this study to assess the perceptions of good health, health-seeking behavior, and health service utilization among adolescents living in a low-income urban neighborhood after the second wave of the COVID-19 pandemic. A total of 23 adolescents, including 12 males and 11 females, were interviewed. Adolescents' perceived body image and size considerations apart from functioning at an optimum physical capacity as the principal attributes of good health, which was possible through the intake of a healthy diet and exercise. Adolescents were likely to be aware of the addiction potential and risk of cancer from using tobacco and alcohol, but attitudes towards eschewing their use were ambivalent. Adolescents perceived themselves as lacking access to reliable, adequate, and validated sources of sexual and reproductive health information. Knowledge and utilization of adolescent health services in this area were negligible, suggestive of the need to strengthen these services and improve the program outreach.

Predictors of Retinal Nerve Fiber Layer Parameters Following Scleral Buckling Surgery in Primary Rhegmatogenous Retinal Detachment.

OBJECTIVE: This study aimed to examine predictors of retinal nerve fiber layer (RNFL) parameters following scleral buckling (SB) surgery for primary rhegmatogenous retinal detachment (RRD) and to determine the influence of the magnitude of change in qualitative and quantitative parameters on RNFL. METHODS:  In an observational prospective study, 40 subjects who underwent successful retinal reattachment with SB surgery done within one month of RRD were evaluated for the parameters of best-corrected visual acuity (BCVA), refractive error, intraocular pressure (IOP), axial length (AL), anterior chamber depth (ACD), angle opening distance (AOD 500 and AOD 750), trabecular iris surface area (TISA 500 and TISA 750), visual fields, and ganglion cell count (GCC) and RNFL before and three months after SB. We additionally noted qualitative factors like extent, location, and type of buckle; phakic status; and grade of proliferative vitreoretinopathy in the affected eye. The change in value of quantitative parameters was found. The influence of baseline values and magnitude of change of quantitative and qualitative parameters on average RNFL thickness and magnitude of change of RNFL thickness after SB was found. RESULTS:  Post-SB, average RNFL thickness reduced from 108.58±20.38 microns to 103.73±17.98 microns (p =0.042). The baseline temporal upper (TU), temporal lower (TL), and nasal lower (NL) RNFL thickness (p=0.01, p=0.02, p=0.01, respectively) and total deviation (TD) values of visual fields (p=0.01) correlated positively while baseline GCC gross loss of volume (p=0.01) correlated negatively with post-operative RNFL thickness. The TU, TL, and NL RNFL thickness (p=0.04, p=0.01, p=0.01, respectively) and average GCC (p=0.04) correlated negatively with the magnitude of change in RNFL. The magnitude of change in baseline parameters after surgery was correlated with the magnitude of change in average RNFL thickness. It was noticed that change in AL (p<0.01), TISA 500 (p=0.02), TISA 750 (p<0.01), GCC focal loss of volume (p=0.02), and temporal RNFL thickness (p<0.01) correlated positively while the change in refractive error correlated negatively (p=0.04). Except for the grade of proliferative vitreoretinopathy (PVR) (p=0.04), none of the qualitative parameters, including extent, type, and location of the buckle; and phakic status, had a significant association with post-operative average RNFL thickness or magnitude of its change. CONCLUSIONS:  The predictors of average RNFL thickness following SB include AL; myopic shift; TISA; visual fields TD; average, TU, TL, and NL RNFL thickness; average GCC, gross and focal loss of volume; and grade of PVR. So an early surgery to prevent preoperative ganglion cell and RNFL loss and progression of PVR is recommended.

The Coenzyme A Level Modulator Hopantenate (HoPan) Inhibits Phosphopantotenoylcysteine Synthetase Activity.

The pantothenate analogue hopantenate (HoPan) is widely used as a modulator of coenzyme A (CoA) levels in cell biology and disease models─especially for pantothenate kinase associated neurodegeneration (PKAN), a genetic disease rooted in impaired CoA metabolism. This use of HoPan was based on reports that it inhibits pantothenate kinase (PanK), the first enzyme of CoA biosynthesis. Using a combination of in vitro enzyme kinetic studies, crystal structure analysis, and experiments in a typical PKAN cell biology model, we demonstrate that instead of inhibiting PanK, HoPan relies on it for metabolic activation. Once phosphorylated, HoPan inhibits the next enzyme in the CoA pathway─phosphopantothenoylcysteine synthetase (PPCS)─through formation of a nonproductive substrate complex. Moreover, the obtained structure of the human PPCS in complex with the inhibitor and activating nucleotide analogue provides new insights into the catalytic mechanism of PPCS enzymes─including the elusive binding mode for cysteine─and reveals the functional implications of mutations in the human PPCS that have been linked to severe dilated cardiomyopathy. Taken together, this study demonstrates that the molecular mechanism of action of HoPan is more complex than previously thought, suggesting that the results of studies in which it is used as a tool compound must be interpreted with care. Moreover, our findings provide a clear framework for evaluating the various factors that contribute to the potency of CoA-directed inhibitors, one that will prove useful in the future rational development of potential therapies of both human genetic and infectious diseases.

Tuberculosis (TB) intervention model targeting mobile population of truckers in Delhi, India.

Collaborative TB and HIV prevention and management activities are essential for reducing the burden of TB disease and achieving favorable outcomes by ensuring early initiation of antiretroviral therapy in the comorbid patients. The Mobile population of truckers and helpers is at higher risk of HIV and also TB infection. OBJECTIVE: The present study assessed the feasibility and opportunities for integrating TB screening and anti-tubercular drug dispensation services to truckers as an additional service utilizing the existing infrastructure and human resources of a targeted intervention (TI) based STI (Khushi) clinic and an integrated counseling and testing center (ICTC) operating at a transport hub and transshipment site in Delhi, India. METHODS: This exploratory operational research study was conducted at the Sanjay Gandhi Transport Nagar (SGTN), off the GT-Karnal highway, in North-west district of Delhi, the Indian capital city during May-Nov' 2016. The proposed methodology for integration of comprehensive TB services within the existing STI/HIV services for the trucker population included a prevention and awareness component using interpersonal sessions, transporter meeting, one-on-one group session and IEC/BCC sessions utilizing a surround and engage technique. TB diagnostic testing and treatment services were provided through the collaboration with the TI/Khushi clinic and ICTC center staff aided by the field assistants. RESULTS: Overall, a total of 833 activity sessions were conducted during the study period among the truckers at the SGTN. During these sessions, 14644 truckers and 1444 other individuals were covered. A total of 297 truckers and 30 other people were referred for testing out of which 283 truckers and 33 others were tested for TB. Of these, ten truckers and four other individuals were found positive for TB. DISCUSSION: The present study provides the first patient (truckers) level evidence from India that routine, provider-initiated voluntary TB testing of truckers coming to avail services at STI and ICTC clinics for prevention and screening of HIV-AIDS is possible. The current practice of referral of HIV patients from the ICTC center to the chest clinic is inefficient since the opportunity costs and financial implications involved may deter patients from testing while the HIV negative but presumptive TB patients are likely to be missed. However, for this collaborative partnership to be successful, further investment regarding human and financial resources is necessary. Existing staff needs sensitization, training and proper incentives for conducting TB related IEC/BCC activities along with that for HIV-AIDS. Furthermore, the deployment of additional personnel is preferable for sputum collection and TB testing with the availability of early reporting at site.

Diabetes self-care in primary health facilities in India - challenges and the way forward.

India has approximately 73 million people living with diabetes and another 37 million with prediabetes while nearly 47% of the diabetes cases are undiagnosed. The high burden of poor glycemic control and early onset of complications with associated economic costs indicates a high prevalence of poor self-management practices. It is well-established that achieving patient-centered primary care consistent with a chronic care model ensures optimum diabetes self-management support and improves long-term clinical and health outcomes in diabetes patients. The public sector primary care system in India provides services free of cost to beneficiaries but lacks patient-centered care that undermines diabetes self-management education and support. Furthermore, factors like poor patient knowledge of diabetes, suboptimal medication adherence, persistent clinical inertia, lack of data for monitoring and evaluation through clinical audit worsens the standards of diabetes care in primary care settings of India. There is a need for government initiatives to be directed towards the provision of comprehensive outpatient care that is inclusive of uninterrupted supply of drugs, provision of essential laboratory investigators, training and availability of qualified diabetes educators and availability of specialist support when required. Furthermore, the integration of depression screening and smoking cessation services at the primary care level is warranted.

Temporal changes in plasma profile of pregnancy-associated glycoprotein, progesterone and estrone sulfate associated with fetal number during early- and mid-pregnancy in goats.

This study was designed to investigate plasma profile of pregnancy-associated glycoprotein (PAG), progesterone (P4) and estrone sulfate (E1S) during early- and mid-pregnancy. The goal was to explore the relationships with values for reproductive variables, to detect the most reliable predictor variable, and to identify the most desirable time point for blood collection for determining fetal number in goats. After ultrasonographic examination at d35-40 post-mating, blood sampling of 15 pregnant goats (total 18) was continued until d114. The PAG profile was characterized by gradual increase during early pregnancy from d26 to d51 and thereafter concentrations were relatively constant until d114 of gestation. The effect of fetal number on plasma PAG, P4 and E1S was first evident on d28, d51 and d26, respectively. During mid-pregnancy, does with twins had a greater (P < 0.05) PAG (S-N = 2.54 ± 0.12 compared with 1.59 ± 0.11), P4 (18.91 ± 0.67 compared with 14.51 ± 0.47 ng/mL) and E1S (16.34 ± 0.76 compared with 11.32 ± 0.44 ng/dL) as compared with does with a singleton fetus. Plasma PAG but not P4 and E1S was positively correlated with fetal number and birth weight of kids during early pregnancy. Multivariate linear regression and discriminant function analyzes allowed for identification of plasma PAG as the most reliable predictor for fetal number and birth weight of kids. Furthermore, d58 was the most suitable single time point for prediction of fetal number using PAG as a biomarker. In conclusion, plasma profile of PAG, P4 and E1S was affected by fetal count. Plasma PAG was identified as the most reliable predictor variable of fetal number and birth weight of kids as compared to plasma P4 and E1S.

Facile synthesis of vanillin-based novel bischalcones identifies one that induces apoptosis and displays synergy with Artemisinin in killing chloroquine resistant Plasmodium falciparum.

The inherent affinity of natural compounds for biological receptors has been comprehensively exploited with great success for the development of many drugs, including antimalarials. Here the natural flavoring compound vanillin has been used as an economical precursor for the synthesis of a series of novel bischalcones whose in vitro antiplasmodial activities have been evaluated against erythrocytic stages of Plasmodium falciparum. Bischalcones 9, 11 and 13 showed promising antiplasmodial activity {Chloroquine (CQ) sensitive Pf3D7 IC50 (µM): 2.0, 1.5 and 2.5 respectively}but only 13 displayed potent activities also against CQ resistant PfDd2 and PfIndo strains exhibiting resistance indices of 1.4 and 1.5 respectively. IC90 (8 µM) of 13 showed killing activity against ring, trophozoite and schizont stages. Further, 13 initiated the cascade of reactions that culminates in programmed cell death of parasites including translocation of phosphatidylserine from inner to outer membrane leaflet, loss of mitochondrial membrane potential, activation of caspase like enzyme, DNA fragmentation and chromatin condensation. The combinations of 13 + Artemisinin (ART) exhibited strong synergy (ΣFIC50:0.46 to 0.58) while 13 + CQ exhibited mild synergy (ΣFIC50: 0.7 to 0.98) to mild antagonism (ΣFIC50: 1.08 to 1.23) against PfIndo. In contrast, both combinations showed marked antagonism against Pf3D7(ΣFIC50: 1.33 to 3.34). These features of apoptosis and strong synergy with Artemisinin suggest that bischalcones possess promising antimalarial drug-like properties and may also act as a good partner drugs for artemisinin based combination therapies (ACTs) against Chloroquine resistant P. falciparum.

Awareness About Anti-Smoking Related Laws and Legislation Among General Population in Slums of Delhi, India.

Introduction: Almost 40% of Delhi's population lives in slums and is vulnerable to tobacco use. It is therefore important to assess their opinion and ensure compliance to antismoking legislation. The present study was undertaken to assess the awareness of the general public residing in slums in Delhi regarding the smoke-free initiative of 2009, 3 years after intensive implementation. Methods: It was a cross-sectional study conducted among participants selected by cluster sampling from the slums in six districts of Delhi using a pretested semistructured questionnaire. A total of 708 slum dwellers were interviewed. Results: Out of the total, only 16.1% (n = 114) of the participants had heard of The Cigarettes and Other Tobacco Products (Prohibition of Advertisement and Regulation of Trade and Commerce, Production, Supply and Distribution) Act, 2003 (COTPA), though, they were aware about some of the provisions of the COTPA. Majority (n = 529; 74.7%) perceived the smoke-free zones as the places where smoking forms of tobacco are banned. Regarding the awareness about the places designated as smoke-free zones, 82.1% (n = 581) of the respondents named educational institutions. About 61% of the people interviewed reported to have seen people smoking at public places on the day of interview while only 21.5% reported to have seen any one getting punished for smoking. Conclusions: Awareness about COTPA was low. The study respondents perceived that no action was being taken against persons acting in violation of the law. Thus, there is a need for stricter implementation of COTPA and increased spreading of awareness among the general public. Implications: While awareness about antismoking legislation among general population (particularly slums) has been studied world over, this has not been the case in India. The study depicts opinion of one of the susceptible populations regarding tobacco control legislation, which has hitherto not been studied in the Indian context. This study has an important implication as it highlights the need for stringent enforcement of antismoking legislation for tobacco control.

Meso level multi-disciplinary approach for reduction of pre-treatment loss to follow-up in Revised National Tuberculosis Control Program, Delhi, India.

BACKGROUND: Universal access to tuberculosis (TB) care services emphasizes early detection and initiation of treatment for all pulmonary TB patients. Pre-treatment loss to follow-up patients needs to be actively tracked and treated to break the chain of transmission in the community. OBJECTIVES: MATERIALS AND METHODS: A questionnaire based cross sectional study of a sample of 340 patients who were pre-treatment loss to follow-up was conducted from November 2011 to March 2012 in Delhi. Qualitative study involved focused group discussions with paramedical providers using a topic outline guide, patients were interviewed using semi-structured questionnaire and brainstorming of program managers to elicit reasons, suggestions and health seeking behavior among those who were pre-treatment loss to follow-up. RESULTS: Preference for private practitioners (64.4%), lack of trust in government health system (26.7%), inconvenient time of Directly Observed Treatment (DOT) centre (18.5%) and wrong patient address (14%) were the main reasons for pre-treatment loss to follow-up. Paramedical provider's opinion elicited in focused group discussion was that there is an increased tendency of pre-treatment loss to follow-up in drug addicts and home-less patients. Brainstorming with program managers revealed that a lack of trust in allopathic system of medicine and human resource constraints were the leading causes of pre-treatment loss to follow-up. A Meso level multi disciplinary model with community participation through Resident Welfare Associations (RWAs) has been designed based on the above findings. The model suggests mutual collaboration between government and non government agencies for promotion of International Standards of TB care in private clinics, de addiction services and social welfare schemes through RWAs. CONCLUSION: There is a need for Advocacy Communication and Social Mobilization on a large scale. Collaboration with Resident Welfare Associations (RWAs) and with practitioners from alternate systems of medicine should be encouraged.

Decadal impact of Directly Observed Treatment Short course program on age and gender among New Infectious Tuberculosis cases in Delhi.

BACKGROUND: Burden of tuberculosis in India remains enormous. The Revised National Tuberculosis Control Programme (RNTCP), based on the Directly Observed Treatment Short course (DOTS) strategy, was launched in 1997 in India. The question of what DOTS has or has not accomplished over the past 15 years is a central technical question. OBJECTIVES: To assess the decadal impact of DOTS strategy on some epidemiological factors such as age and gender of new sputum positive (NSP) TB patients in Delhi. MATERIAL AND METHODS: Secondary Data for Delhi was obtained from the state wise performance of RNTCP (Annual Summary) for the year 2001 and year 2012. Data was analyzed in Microsoft Excel 2007. RESULTS: The population of Delhi covered under DOTS has considerably increased over the decade. The case detection rate has also shown a considerable increase from 196/100,000 population in 2001 to 306/100,000 population at the end of Quarter 3 of 2011. The number of NSP male and female patients have increased in all age groups from 2001 to 2011 except in 25-34 years age group. NSP male patients on DOTS aged 15-44 years showed a left ward shift in increase, a significant right ward shift was noted in increase in female NSP patients of similar age group. CONCLUSIONS: The decadal assessment of DOTS in Delhi on TB epidemiology has pointed towards beginning of epidemiological transition in TB control in India.

Protein kinase C Beta in the tumor microenvironment promotes mammary tumorigenesis.

Protein kinase C beta (PKCß) expression in breast cancer is associated with a more aggressive tumor phenotype, yet the mechanism for how PKCß is pro-tumorigenic in this disease is still unclear. Interestingly, while it is known that PKCß mediates angiogenesis, immunity, fibroblast function and adipogenesis, all components of the mammary tumor microenvironment (TME), no study to date has investigated whether stromal PKCß is functionally relevant in breast cancer. Herein, we evaluate mouse mammary tumor virus-polyoma middle T-antigen (MMTV-PyMT) induced mammary tumorigenesis in the presence and absence of PKCß. We utilize two model systems: one where PKCß is deleted in both the epithelial and stromal compartments to test the global requirement for PKCß on tumor formation, and second, where PKCß is deleted only in the stromal compartment to test its role in the TME. MMTV-PyMT mice globally lacking PKCß live longer and develop smaller tumors with decreased proliferation and decreased macrophage infiltration. Similarly, when PKCß is null exclusively in the stroma, PyMT-driven B6 cells form smaller tumors with diminished collagen deposition. These experiments reveal for the first time a tumor promoting role for stromal PKCß in MMTV-PyMT tumorigenesis. In corroboration with these results, PKCß mRNA (Prkcb) is increased in fibroblasts isolated from MMTV-PyMT tumors. These data were confirmed in a breast cancer patient cohort. Combined these data suggest the continued investigation of PKCß in the mammary TME is necessary to elucidate how to effectively target this signaling pathway in breast cancer.

Resurrecting social infrastructure as a determinant of urban tuberculosis control in Delhi, India.

BACKGROUND: The key to universal coverage in tuberculosis (TB) management lies in community participation and empowerment of the population. Social infrastructure development generates social capital and addresses the crucial social determinants of TB, thereby improving program performance. Recently, there has been renewed interest in the concept of social infrastructure development for TB control in developing countries. This study aims to revive this concept and highlight the fact that documentation on ways to operationalize urban TB control is required from a holistic development perspective. Further, it explains how development of social infrastructure impacts health and development outcomes, especially with respect to TB in urban settings. METHODS: A wide range of published Government records pertaining to social development parameters and TB program surveillance, between 2001 and 2011 in Delhi, were studied. Social infrastructure development parameters like human development index along with other indicators reflecting patient profile and habitation in urban settings were selected as social determinants of TB. These include adult literacy rates, per capita income, net migration rates, percentage growth in slum population, and percentage of urban population living in one-room dwelling units. The impact of the Revised National Tuberculosis Control Program on TB incidence was assessed as an annual decline in new TB cases notified under the program. Univariate linear regression was employed to examine the interrelationship between social development parameters and TB program outcomes. RESULTS: The decade saw a significant growth in most of the social development parameters in the State. TB program performance showed 46% increment in lives saved among all types of TB cases per 100,000 population. The 7% reduction in new TB case notifications from the year 2001 to 2011, translates to a logarithmic decline of 5.4 new TB cases per 100,000 population. Except per capita income, literacy, and net migration rates, other social determinants showed significant correlation with decline in new TB cases per 100,000 population. CONCLUSIONS: Social infrastructure development leads to social capital generation which engenders positive growth in TB program outcomes. Strategies which promote social infrastructure development should find adequate weightage in the overall policy framework for urban TB control in developing countries.

Should there be mandatory testing for HIV prior to marriage in India?

The National AIDS Prevention and Control Policy of the government of India states that testing for HIV infection should be voluntary in nature. But from time to time various state governments and the central government have announced their intent of introducing mandatory premarital testing. Though this intent has not yet been translated into action, we present our case against the adoption of such a policy by discussing various social and medical issues. These include the limited population that such a policy would target given the early age of marriage in India; issues related to its implementation considering the low marriage registration rates in India; potential of stigma and discrimination associated with it; issues with defining boundaries and the role of the state; limitations related to the HIV test itself in context of the policy, including the window period and the positive predictive value of the test; its limited impact in population groups at a high risk for HIV infection; its limited role in changing unsafe behaviours; its limited potential to enhance the empowerment of women; its conflict with existing human rights; and the adverse experience of other countries with a similar policy.

Microwave-assisted efficient extraction of different parts of Hippophae rhamnoides for the comparative evaluation of antioxidant activity and quantification of its phenolic constituents by reverse-phase high-performance liquid chromatography (RP-HPLC).

The outcome of different extraction procedures (microwave, ultrasound, Soxhlet, and maceration) on the antioxidant activity of seeds, leaves, pulp, and fruits of Hippophae rhamnoides (sea buckthorn or SBT) was investigated by two different bioassays: 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) and 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays. The SBT extracts were found to possess strong antioxidant activity measured in terms of TEAC (2.03-182.13 and 6.97-282.75 mg/g) with ABTS and DPPH assays, respectively. In general, the antioxidant capacity of microwave-assisted extracts was found to be significantly higher than those obtained by ultrasound-assisted extraction (UAE) and maceration while being slightly higher than Soxhlet extracts. Further, microwave extracts of seeds were found to possess maximum antioxidant capacity followed by leaves, fruits, and pulp. Also, the chemical composition of extracts, studied in terms of the total phenolic content, was found to be in the range of 1.9-23.5 mg/g Gallic acid equivalent (GAE), which indicates a strong correlation between antioxidant activity and phenolic content present in the SBT. In addition, some of its bioactive phenolic constituents, such as rutin ( 1), quercetin-3- O-galactoside ( 2), quercetin ( 3), myricetin ( 4), kaempferol ( 5), and isorhamnetin ( 6), were also quantified in different extracts by reverse-phase high-performance liquid chromatography (RP-HPLC).

Changing profile of disease contributing to mortality in a resettlement colony of Delhi.

BACKGROUND: The past decade has seen a decline in the disability-adjusted life years (DALYs) contributed by communicable diseases while lifestyle changes and rapid urbanization have led to an increase in DALYs contributed by non-communicable diseases. We studied the causes of death in a low socioeconomic area over 11 years to help identify changes in the pattern of disease. METHODS: We did this study in Gokulpuri, a resettlement colony in East Delhi. All deaths occurring from 1994 to 2004 were analysed using a verbal autopsy questionnaire completed by trained health workers during their home visits in the area. RESULTS: A total of 515 deaths occurred during the period; 340 in men (66%) and 175 in women (34%). The six commonest causes of death were tuberculosis (24.8%), chronic obstructive pulmonary disease (11.6%), pneumonia (8.7%), accidents and poisoning (8.6 %), coronary heart disease (8.2%) and cancer (4.6%). The age-specific mortality rate was highest among people > 45 years of age. The cause-specific mortality rate due to communicable diseases showed a decline while that due to non-communicable diseases showed a rising trend in all age groups. CONCLUSION: Our study shows the coexistence of communicable and non-communicable diseases in a low socioeconomic area with a rising trend in non-communicable diseases. Surveillance for risk factors of non-communicable diseases should be done even in predominantly low socioeconomic areas. The coexistence of communicable and non-communicable diseases and the increase in non-communicable diseases among the economically deprived sections of our society suggest the need to re-prioritize components of healthcare among these sections.

Drug use among juveniles in conflict with the law.

OBJECTIVE: To study the pattern of drug use, reasons for initiation and the perception about the effects of using drugs, among juveniles in conflict with law. METHODS: A qualitative study was conducted at Prayas Observation Home for boys, New Delhi. Eight key informant interviews were conducted to find the prevalence of prior drug use among boys. Five focus group discussions were conducted with 34 children using a topic outline guide. RESULTS: The study showed that drug use was related to other criminal activities. Peer group and media were the most important influences for initiation of drug use. All kinds of drugs could easily be procured by children and there was a gradual progression from non-use to tobacco and alcohol use, to marijuana and ultimately to other drugs. Knowledge about medical and social mal-effects of consuming drugs did not seem to effect either the consumption of drugs or the desire to leave this habit. CONCLUSION: Results of the study demonstrate an urgent need for taking stringent measures in order to curb drug use among adolescents.
