Abstract
ABSTRACT The developmental anomaly of the middle cerebral artery (MCA) is a rare occurrence. Rete MCA, also known as "unfused," "twig-like," and aplastic MCA, is an even rarer anomaly. These immature rete vessels are prone to flow-related aneurysms which rupture themselves presenting with intraparenchymal hematoma. We here with present a case of rete MCA with a ruptured aneurysm and discuss its pathophysiology and management.

Abstract
BACKGROUND Women's health is usually looked upon in terms of their reproductive health. However, cardio-vascular diseases are one of the leading causes of death and disability among women, globally as well as in India. Risk factors of today can be disease of tomorrow. Gradience in level of epidemiological transition is observed across different states. The study aims to estimate the national and regional prevalence, and sociodemographic determinants of biological and behavioural risk factors for cardiovascular diseases. MATERIALS AND METHODS The present study was conducted among women in the age group of 15 to 49 years using nationally representative sample from fifth round National Family Health Survey in India. The data analysis in the current study included 7,24,115 women in the age group of 15 to 49 years. SPSS version 20 was used for the purpose of analysis. Weighted prevalence was computed for the studied behavioral and biological (dependent variable) risk factors using women specific weights as provided in the dataset. Binary logistic regression model was employed to calculate the adjusted odds ratio (OR) with the corresponding 95% confidence interval (CI) to study the sociodemographic determinants (independent variables) of these risk factors. RESULTS Highest prevalent risk factor for cardiovascular diseases was reported to be central obesity (78.2%), followed by overweight/obesity (23.9%), oral contraceptive use (13.4%), raised blood pressure (11.8%), raised blood sugar (8.6%), tobacco use (4.0%), and alcohol use (0.7%). Higher odds of all the studied risk factors were reported with increasing age. All of the studied risk factors, except for alcohol consumption [OR (95%CI): 0.9 (0.8-0.96)], had higher odds in rural areas compared to urban areas. Compared to other castes, the odds of tobacco [OR (95% CI): 2.01 (1.91-2.08)] and alcohol consumption [OR (95% CI): 5.76 (5.12-6.28)], and raised blood pressure [OR (95% CI): 1.07(1.04-1.11)] was significantly higher among the people belonging to schedule tribe. CONCLUSION AND RECOMMENDATION The present study highlights the state-wise disparities in the burden and predictors of risk factors for cardio-vascular diseases among women of reproductive age. The study provides insights to these disparities, and focuses on the need of tailoring the disease prevention and control measures suiting to the local needs.

Abstract
Background India, as a nation is witnessing epidemiological transition, which is taking place across all the states at different level, over past couple of decades. Owing to the long natural history of non-communicable diseases (NCDs), early identification of these risk factors can aid in understanding the distribution and future development of cardiovascular diseases (CVDs). Also, studying the trend of these risk factors over time can help in prediction of burden of various CVDs in future. Thus, the present study aims at understanding the trend of various risk factors for CVDs across rural and urban India, and states. Methods The present study was conducted using secondary data from the third, fourth and fifth round of the National Family Health Survey (NFHS) conducted in India. The surveys collected data for estimation of burden of the common modifiable risk factors of CVDs including tobacco and alcohol consumption overweight/obesity, raised blood pressure, and raised blood sugar. The analysis for the present study was done among interviewed males and females between 15 and 49 years. The weighted prevalence of these risk factors was computed and binary logistic regression was done to study the predictors for the same. Results A declining trend of tobacco (29.2% in NFHS 3; 8.1%in NFHS 5) and alcohol consumption (14.2% in NFHS 3; 3.2%in NFHS 5) was observed from 2005 -06 to 2019-21. A rising trend of overall raised blood pressure (11.4% in NFHS 4; 12.2%in NFHS 5), raised blood sugar (6.2% in NFHS 4; 8.5%in NFHS 5), and overweight and obesity (11.4% in NFHS 3; 23.6%in NFHS 5) was observed from the three rounds of the survey. The odds of all the studied risk factors were significantly higher among older age across all the rounds of the survey. Except overweight/obesity, the odds of rest all studied risk factors was found to be higher among males compared to females. Also, higher odds of alcohol consumption, overweight/obesity, raised blood pressure, and raised blood sugar were found among the participants living in urban areas compared to rural areas, across all the rounds of the survey. Conclusion The present highlights the rising burden of CVD risk factors, including overweight and obesity, raised blood pressure and raised blood sugar, and a declining trend of tobacco and alcohol consumption across the country. The study also highlights the need for in-depth assessment of predictors of these risk factors using longitudinal study designs.

Abstract
Aerosols are one of the significant external sources of soluble reactive nitrogen to the surface ocean and their deposition affects the primary productivity. Owing to rapid industrialization over South and Southeast Asia, an increasing trend in atmospheric pollutants was observed over the northern Indian Ocean (NIO). To assess the contribution of the aeolian supply of inorganic nitrogen to the NIO, the available compositional data of marine aerosols collected over this basin between 2001 and 2020 were compiled. Based on the observed relationship of mass load, and particulate nitrate and ammonium concentrations with the corresponding satellite-derived anthropogenic aerosol optical depth (AAOD), the temporal, spatial, and long-term variabilities were derived for the past two decades. In particular, high aerosol mass load, nitrate and ammonium levels were observed in the coastal aerosols of peninsular India during fall and winter and they were low in summer. The atmospheric input of inorganic nitrogen to the Arabian Sea is higher (AS; 1.7 TgN per year) compared to that of the Bay of Bengal (BoB; 0.9 TgN per year) and accounts for ∼30% of the total external sources of nitrogen to the NIO. The new production, supported by external sources of nitrogen, contributes to ∼23 and 53% of export production to the oxygen minimum zone (OMZ) in the AS and BoB respectively. A significant rate of increase in the aerosol mass load (0.05-1.67 μg per m3 per year), and nitrate (0.003-0.04 μg per m3 per year) and ammonium (0.006-0.11 μg per m3 per year) concentrations was observed between 2001 and 2020, likely because of the increased emission of anthropogenic pollutants over South and Southeast Asia and their subsequent long-range atmospheric transport to the NIO. Overall, these results suggest that an enhanced contribution of atmospheric nitrogen may potentially increase (1) the N/P ratio of the surface ocean that impacts phytoplankton composition, (2) export production to the OMZ leads to intensification, and (3) sequestration of atmospheric CO2. A decrease in primary production due to global warming is reported due to a decrease in vertical nutrient supply; however, the increase in atmospheric deposition of nutrients may compensate for this. Therefore, ocean models must be coupled with atmospheric models to better constrain the oceanic response to climate change in the NIO.

Abstract
Background Adherence to medications is one of the key determinants of therapeutic control of high blood pressure and is seen as a bottleneck in our fight against hypertension control. We have little scientific evidence from India that highlights the determinants of treatment adherence. Aim The purpose of this study was to identify the predictor adherence to the currently prescribed antihypertensive medications. Material and Methods We did a secondary data analysis of the National Family Health Survey, 2015-2016 datasets. As there were no direct variables to measure adherence, this was derived from the responses to the survey question: "currently taking a prescribed hypertensive medication to lower Blood Pressure" among those already diagnosed as hypertensives by the physician. The other sociodemographic and household-level variables were used as independent variables for analysis. Results The level of awareness about their hypertensive status among the 15-49-year-olds who were subjected to blood pressure measurement was 9.34% (70,267/80,3081). Of these, 70,267 participants, 65878 with valid hypertensive individual data were included in the final analysis. Among them, 26.78% are currently adhering to antihypertensive medication. Female gender (adj OR; 95% CI: 1.17 [1.09-1.24]) and non-reserved caste ([OR] 1.24; 95% [CI]: 1.18-1.32) depicted better adherence to the current treatment. The hypertensives who preferred taking treatment from shops or at home or some other place in comparison to health facilities had a significant association with adherence (adj OR: 1.64; 95% CI: [1.43-1.88]). Conclusion The current study reported low adherence to the current antihypertensive medication. Gender, higher age group, obesity, and place of taking the treatment were strongly associated with adherence to treatment.

Abstract
The sudden upsurge in the newly emerging COVID-19 variants acted as a catalyst for India to scale up the viral Genomic surveillance in order to understand the nature and trends of the newer variants of concern and strengthen public health interventions across the country. The Government of India has proposed the Indian SARS-CoV-2 Genomics Consortium to expand the whole-genome sequencing (WGS) of this virus. However, in a vast country like India introduction and implementation of any new strategies amidst the already existing barriers due to COVID-19 will be a herculean task. This paper talks about how the primary care physicians can play a vital role in successful implementation of the above strategy in addition to the surveillance systems in India.

Abstract
Perennial increase in atmospheric pollution over the Bay of Bengal (BoB) and South China Sea is reported due to increase in human population and industrial activity in South and Southeast Asia. Based on total aerosol optical depth (AOD) derived from MODIS (moderate resolution imaging resolution imaging spectroradiometer), natural and anthropogenic fractions were derived. The seasonality and spatial variability in rate of increase in total, natural, and anthropogenic AOD fractions were examined over the BoB using data collected between 2001 and 2019. Both total and anthropogenic AOD displayed statistically significant rate of increase in the northwest BoB (NWB) and western coastal BoB (WCB) regions during 2001 to 2019 whereas the long-term changes are insignificant in the other regions of BoB. Significant increase in AOD in the NWB and WCB regions is mainly contributed by dominant outflow of anthropogenic emissions from Indo-Gangetic Plain (IGP) area of Indian subcontinent. The magnitude of AOD decreased by half from northern BoB to equatorial region due to increase in distance from the source region. The contribution of anthropogenic AOD was >70% to total AOD with higher contribution during winter and lower during summer. The rate of increase in both total and anthropogenic AOD was close to 0.104 and 0.099 per decade in the NWB and 0.069 and 0.059 per decade in the WCB region between 2001 and 2019. The rate of increase in total and anthropogenic AOD decreased from 2001-2009 (0.164 and 0.115 per decade respectively) to 2010-2019 (0.068 and 0.076 per decade respectively) in the NWB region. Significant increase in anthropogenic AOD by 50 and 30% was observed during El Niño and La Niña periods respectively than normal year in both northwest BoB (NWB) and western coastal (WCB) regions due to change in strength and direction of winds. Although some fraction of anthropogenic AOD is found over the entire BoB, significant rate of increase in anthropogenic AOD is found only about 23% of the area of BoB than hitherto reported as entire BoB. The impact of atmospheric deposition of anthropogenic aerosols on biogeochemical processes, such as primary production and ocean acidification, needs further evaluation.

Abstract
Background: Public health emergencies during pandemics of communicable diseases, may cause fear leading to social isolation and stigma. Cases have been reported of healthcare professionals (HCPs), facing discrimination on account of heightened fear and misinformation. However, there is dearth of literature with regards to the nature and magnitude of this stigma. Hence, this study was conducted to assess perceived and experienced stigma related to the Coronavirus disease 2019 (COVID-19) among HCPs and also assess their apprehensions about testing, quarantine/isolation and consuming Hydroxy-chloroquine as prophylaxis (HCQ).Methods: A cross-sectional study was undertaken among the HCPs working in Delhi during the period May to July 2020. The study was conducted using a semi-structured online questionnaire which was circulated on official contact numbers and email IDs of HCPs in the Google.doc format.Result: Seventy percent of the participants in the current study perceived some kind of stigma, 50% of study participants perceived some form of stigma in their residential colony, 46% observed change in behaviour of their neighbours. Around 20% of participants experienced stigma, most commonly being rude behaviour or harassment from neighbour/landlord. A statistically significant association was observed between marital status (p=0.038), designation (p=0.021) and place of stay (p=0.013) of the study participants and perceived stigma among them. The level of awareness regarding HCQ was high (94.3%), but more than 60% didn’t consume it due to apprehension about side effects.Conclusion: In view of the substantial stigma faced by the HCP, necessary measures to curb the fear and dispel misinformation related to COVID-19 must be undertaken. the rural population.

Abstract
PURPOSE Prostate specific antigen has limited performance in detecting prostate cancer. The transcription factor GATA2 is expressed in aggressive prostate cancer. We analyzed the predictive value of urine extracellular vesicle GATA2 mRNA alone and in combination with a multigene panel to improve detection of prostate cancer and high risk disease. MATERIALS AND METHODS GATA2 mRNA was analyzed in matched extracellular vesicles isolated from urines before and after prostatectomy (16) and paired urine and tissue prostatectomy samples (19). Extracellular vesicle GATA2 mRNA performance to distinguish prostate cancer and high grade disease was tested in training (52) and validation (165) cohorts. The predictive value of a multigene score including GATA2, PCA3 and TMPRSS2-ERG (GAPT-E) was tested in both cohorts. RESULTS Confirming its prostate origin, urine extracellular vesicle GATA2 mRNA levels decreased significantly after prostatectomy and correlated with prostate cancer tissue GATA2 mRNA levels. In the training and validation cohort GATA2 discriminated prostate cancer (AUC 0.74 and 0.66) and high grade disease (AUC 0.78 and 0.65), respectively. Notably, the GAPT-E score improved discrimination of prostate cancer (AUC 0.84 and 0.72) and high grade cancer (AUC 0.85 and 0.71) in both cohorts when compared with each biomarker alone and PT-E (PCA3 and TMPRSS2-ERG). A GAPT-E score for high grade prostate cancer would avoid 92.1% of unnecessary prostate biopsies, compared to 61.9% when a PT-E score is used. CONCLUSIONS Urine extracellular vesicle GATA2 mRNA analysis improves the detection of high risk prostate cancer and may reduce the number of unnecessary biopsies.

Abstract
Knowledge on the variability in quantity and compositions of various size groups of aerosols is important to understand their sources and their role in biogeochemical and climate processes. Here, we studied total suspended particles (TSP), PM10 and PM2.5 for their quantitative and water soluble compositional (F-, Cl-, SO42-, NO3-, NH4+, Na+, K+, Ca2+, and Mg2+) distributions, and to understand their nature and potential sources at Goa and Visakhapatnam on the west and east coasts, respectively, of India. While the mean concentrations of TSP were found to be 117 ± 44 and 85 ± 51 μg/m3 its maximal levels occurred in spring intermonsoon (SIM; 141 ± 52) and winter monsoon (WM; 155 ± 145 μg/m3) seasons at Goa and Visakhapatnam, respectively. PM10 and PM2.5 exhibited higher ranges at Visakhapatnam than Goa. The increase in PM2.5 abundance from WM to SIM at Visakhapatnam seems to occur in coincidence with decrease in TSP favored by topography and ambient meteorological conditions. Locally released and seasonally transported (from land and sea) constituents contributed to the observed variability in aerosol compositions. Sulphate dominated the aerosol composition at both Goa (57-64%) and Visakhapatnam (43-55%) followed by NO3- (5-16% and 6-18%, respectively) where the former component was higher in PM10 and PM2.5. The NO3- was more in TSP. Relations between SO42- and NH4+ suggested possible presence of NH4HSO4. Examination of ionic ratios and balance suggested near neutrality in PM10 and PM2.5 while TSP was acidic at the both locations. Notable relations between Ca2+ and NO3-, particularly in PM10 at Goa, indicated their release from mining related activities.

Abstract
OBJECTIVES A randomized controlled study was conducted with 422 homeless, stimulant-using gay/bisexual (G/B) men and 29 transgender women (n = 451) to assess two community-based interventions to reduce substance abuse and improve health: (a) a nurse case-managed program combined with contingency management (NCM + CM) versus (b) standard education plus contingency management (SE + CM). STUDY DESIGN Hypotheses tested included: a) completion of hepatitis A/B vaccination series; b) reduction in stimulant use; and c) reduction in number of sexual partners. METHODS A deconstructive cost analysis approach was utilized to capture direct costs associated with the delivery of both interventions. Based on an analysis of activity logs and staff interviews, specific activities and the time required to complete each were analyzed as follows: a) NCM + CM only; b) SE + CM only; c) time to administer/record vaccines; and d) time to receive and record CM visits. Cost comparison of the interventions included only staffing costs and direct cash expenditures. RESULTS The study outcomes showed significant over time reductions in all measures of drug use and multiple sex partners, compared to baseline, although no significant between-group differences were detected. Cost analysis favored the simpler SE + CM intervention over the more labor-intensive NCM + CM approach. Because of the high levels of staffing required for the NCM relative to SE, costs associated with it were significantly higher. CONCLUSIONS Findings suggest that while both intervention strategies were equally effective in achieving desired health outcomes, the brief SE + CM appeared less expensive to deliver.

Abstract
A 16-year-old white man was involved in a motor vehicle collision and suffered head, chest, and abdominal trauma. Despite initial resuscitative efforts, he progressed to brain death and was designated to be an organ donor by his family. He had no earlier medical or surgical history and no high-risk behaviors. Blood work revealed normal creatinine, liver function tests, lipase, and amylase. Viral serologies were negative except for cytomegalovirus IgG and Epstein-Barr virus nucleic acid. Imaging revealed a right kidney contusion, a manubrial fracture, and fractures of right first rib and bilateral scapulae. No other abdominal trauma was identified, specifically to the pancreas, duodenum, or spleen. Our transplant center accepted the pancreas from this donor. During back-table inspection of the pancreas, a 1.5 × 1.5 cm dark purple rubbery mass was identified within the parenchyma of the pancreas in the tail. An incisional biopsy of the lesion was sent for frozen section, which yielded a mixed inflammatory infiltrate consisting of neutrophils and lymphocytes and an overlying fibrous capsule. The diagnosis of lymphoma or another neoplasm could not be definitely ruled out. Owing to uncertainty in diagnosis, the entire lesion was excised along with the distal pancreas with the use of a linear stapler. The staple line was oversewn with running 4-0 polypropylene suture, and the pancreas was transplanted. After surgery, the pancreas allograft functioned well with a small pancreatic leak, which had resolved by the first postoperative outpatient visit.

Abstract
AIMS Our comprehensive review highlights the drug development and pharmacogenomics leading to the recent approval of PCSK9 inhibitors. We also review the anticipated future advances into the uses of PCSK9 inhibition. BACKGROUND Despite the present advances in pharmacotherapy, atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of mortality worldwide. Low density lipoprotein-cholesterol (LDL-C) lowering is the primary target for ASCVD risk reduction, showing demonstrable benefits in mortality. However, 70% of events occur even in the presence of statins. This residual risk may be approached with additional LDL-C reduction. Statin intolerance is a common clinical concern affecting adherence and the benefit with statins. There is also significant variation of individual lipid-lowering. Following rapid development, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors have progressed from genetic observations, to mechanistic studies, to closer realization of the goal of CVD risk reduction. This review discusses the science behind PCSK9 inhibition, evidence of trials involving efficacy and safety, and reflections of its present and future role in clinical care, especially in high-risk patients with ASCVD, persons with suboptimal responses to statins and familial hyperlipidemia. Monoclonal antibodies have demonstrated LDL-C lowering of up to 57% as monotherapy and up to 73% when added to statins. Statins have limited efficacy in reduction of LDL-C due to an increased number of LDL-receptors. Elevated lipoprotein (a) levels may also be significantly lowered by PCSK9i. The journey from discovery to PSCK9 target validation took less than five years, and development and approval of therapeutic modalities for PCSK9 inhibitors happened over the next seven. This review highlights the drug development and pharmacogenomics leading to the recent approval of two agents, alirocumab and evolocumab, with a third bococizumab, and other novel approaches to the pathway pending. DATA SYNTHESIS We searched MEDLINE database via Pubmed for reviews, research publications and relevant trials available on PCSK9 inhibition. CONCLUSION Despite decades of medical advances, ASCVD remains one of the major causes of morbidity and mortality worldwide. Statin use has multiplied since the validation of LDL hypothesis, however, it is undeniable a more effective and well-tolerated agent is needed in significant number or patients. With the arrival of the era of unprecedented CV protection with PCSK9 inhibition, this exciting new therapy holds a pivotal promise as the future of lipid management. The data available already indicate safety, tolerability and superb efficacy of these agents, which are already changing contemporary cholesterol management. The rapid translation of innovative basic science research into drug development may lead to CV outcomes reduction and confirm that this pathway will become prominently utilized.

Abstract
A panel of 129 Giemsa-stained thick blood spots (TBS) confirmed for Plasmodium falciparum infection having different levels of parasite density were collected from a malaria endemic area. DNA was extracted and nested polymerase chain reaction (PCR) assay was performed to amplify P. falciparum DNA. Nested PCR assay successfully amplified P. falciparum DNA at a very low parasitaemia of ~10 parasites/μl of blood. Current PCR assay is very simple and can be used retrospectively to monitor the invasion and prevalence of different Plasmodium species in endemic areas.

Abstract
Systemic lupus erythematosus (SLE) is characterized by over production of autoantibodies. C-reactive protein (CRP) is a phylogenetically highly conserved plasma protein that participates in the systemic response to inflammation. Anti-CRP antibodies might have biological functions of pathogenetic interest in SLE. We evaluated anti-CRP antibodies in Indian SLE patients and their association with anti-dsDNA antibodies and complement levels (C3 and C4). One hundred SLE patients diagnosed according to the American College of Rheumatology criteria were included. Disease activity was assessed using SLE disease activity index (SLEDAI). Anti-CRP autoantibodies were detected by enzyme linked immunosorbent assay. Anti-dsDNA antibodies were detected by indirect immunofluroscence test (Euroimmun Lubeck, Germany). High sensitivity CRP and complement levels (C3, C4) were detected using a Nephelometer. (BN ProSpec, Dade Behring, Germany). Anti-CRP antibodies were detected in 26% of SLE patients. Mean age of disease onset among anti-CRP positives was 22.4 ± 7.5, and 26.6 ± 9.3 years among anti-CRP negatives (P > 0.05). Anti-dsDNA positivity was significantly higher among anti-CRP positives (32.7%) as compared to anti-CRP negatives (16%) (P = 0.00519). No statistically significant difference was observed in SLEDAI scores of anti-CRP positive group and anti-CRP negative group (P > 0.05). We observed a positive correlation between anti-CRP antibodies and anti-dsDNA antibodies.

Abstract
OBJECTIVE To identify the malaria hot spots at health subcentre level in an endemic district using a geographical information system (GIS). The results will be useful for rapid retrieval of malaria information, and to prioritize malaria control efforts in identified hot spots. STUDY DESIGN Extraction, analysis and synthesis of relevant data. METHODS Malaria epidemiological data from 2006 to 2009 were analysed to determine the annual parasitic index, slide positivity rate, annual blood examination rate and Plasmodium falciparum percentage for each health subcentre in the district. Maps were produced using GIS, and integrated to identify the malaria hotspots. RESULTS Out of 288 health subcentres, GIS identified 10 hot spots at extremely high risk of malaria and 14 hot spots at high risk of malaria. Malaria may flare up in these hot spots whenever favourable transmission conditions arise. Health authorities have been advised to establish control measures in these selected hot spots for timely prevention. CONCLUSION There is a need for adequate monitoring and allocation of available resources for better interventions in the malaria hotspots. The GIS model used in this study can be used, even at village or cluster level, to pin point the malaria hot spots, and information can be updated and retrieved easily.

Abstract
Tor tor is an important game and food fish of India with a distribution throughout Asia from the trans-Himalayan region to the Mekong River basin to Malaysia, Pakistan, Bangladesh and Indonesia. A new cell line named TTCF was developed from the caudal fin of T. tor for the first time. The cell line was optimally maintained at 28°C in Leibovitz-15 (L-15) medium supplemented with 20% fetal bovine serum (FBS). The propagation of TTCF cells showed a high plating efficiency of 63.00%. The cytogenetic analysis revealed a diploid count of 100 chromosomes at passage 15, 30, 45 and 60 passages. The viability of the TTCF cell line was found to be 72% after 6 months of cryopreservation in liquid nitrogen (-196°C). The origin of the cell lines was confirmed by the amplification of 578- and 655-bp sequences of 16S rRNA and cytochrome oxidase subunit I (COI) genes of mitochondrial DNA (mtDNA) respectively. TTCF cells were successfully transfected with green fluorescent protein (GFP) reporter plasmids. Further, immunocytochemistry studies confirm its fibroblastic morphology of cells. Genotoxicity assessment of H₂O₂ in TTCF cell line revealed the utility of TTCF cell line as in vitro model for aquatic toxicological studies.

Abstract
Malaria remains a complex problem during the pregnancy, which threatens > 35 millions pregnant women every year. Malaria pathogenesis in pregnancy results in accumulation of infected RBCs in the intervillous spaces causing severe alterations leading to the reduced materno-foetal exchanges. In this article we have revisited the current evidences of clinical implications and overall burden of malaria in pregnancy. Many adverse aftermaths including, low birth weight, intrauterine growth retardation, preterm delivery, stillbirth and anemia were found associated with malaria in pregnant women. Despite of worldwide comprehensive control programmes for malaria in pregnancy, the disease control has been a daunting task everywhere. Socio cultural, economical, lack of awareness and various logistic problems compound the disease in developing countries. Thorough evidence based information and estimates, education and awareness and strengthening of prevention programmes are needed urgently to achieve success in malaria control in pregnancy.

Abstract
BACKGROUND Increased scrutiny and the need to institute a truly patient centered approach to surgical care has motivated the growing interest in measuring the quality of surgical care through comparative surgical audit. This study aimed to assess the validity of the POSSUM (Physiological and Operative Severity Score for enumeration of Mortality and Morbidity) and P-POSSUM (Portsmouth-POSSUM) score in predicting the risk of morbidity and mortality respectively in general surgical patients presenting with conditions of various operative severities at a tertiary care centre in Haryana, a northern state of India. METHOD A prospective study was performed in 100 general surgical patients including an equal number of patients in each of the four groups of operative severity i.e. minor, moderate, major, major plus. The risks of mortality and morbidity were calculated by using the POSSUM equation for morbidity and the P-POSSUM equation for mortality in each patient. The predicted risks were compared with the observed risks of mortality and morbidity and statistically analysed. RESULTS The difference in p value of predicted risk of morbidity by POSSUM equation and observed morbidity; calculated by chi square test was 0.756 which was not statistically significant. The difference in p value of predicted mortality by P-POSSUM equation and observed mortality; calculated by chi square test was 0.472 which was also not statistically significant. CONCLUSION POSSUM and P-POSSUM appear to be good and valid indices for use in the risk prediction of morbidity and mortality in the north Indian population.

Abstract
Measles is a childhood disease that causes great morbidity and mortality in India and worldwide. Because measles surveillance in India is in its infancy, there is a paucity of countrywide data on circulating Measles virus genotypes. This study was conducted in 21 of 28 States and 2 of 7 Union Territories of India by MeaslesNetIndia, a national network of 27 centers and sentinel practitioners. MeaslesNetIndia investigated 52 measles outbreaks in geographically representative areas from 2005 through June 2010. All outbreaks were serologically confirmed by detection of antimeasles virus immunoglobulin M (IgM) antibodies in serum or oral fluid samples. Molecular studies, using World Health Organization (WHO)-recommended protocols obtained 203 N-gene, 40 H-gene, and 4 M-gene sequences during this period. Measles genotypes D4, D7, and D8 were found to be circulating in various parts of India during the study period. Further phylogenetic analysis revealed 4 lineages of Indian D8 genotypes: D8a, D8b, D8c, and D8d. This study generated a large, countrywide sequence database that can form the baseline for future molecular studies on measles virus transmission pathways in India. This study has created support and capabilities for countrywide measles molecular surveillance that must be carried forward.

Abstract
Time resolved fluorescence spectroscopy (TRFS) of Eu(III) (an analogue of trivalent actinides) complexation with humic acid (HA) and its model compounds, namely phthalic acid (PA), mandelic acid (MA) and succinic acid (SA) has been carried out at varying concentration ratios of ligand to metal ion. The emission spectra were recorded in the range of 550-650nm by exciting at an appropriate wavelength. The intensity of the 616nm peak of Eu(III) was found to be sensitive to complexation. The ratio of the intensities of 616 and 592nm peaks was used to determine the stability constants of Eu-phthalate, Eu-mandelate and Eu-succinate complexes. In the case of model compounds, the life-time was found to increase with increasing ligand to metal ratio (L/M) indicating the decrease in quenching of the fluorescence by coordinated water molecules with increasing complexation. On the other hand in the case of HA, the life-time was found to be constant at least up to L/M of 5, indicating the formation of outer sphere complex. Beyond L/M=5 the life-time value was found to increase which can be attributed to the binding of the metal ion to the higher affinity sites in the HA macromolecule.

Abstract
Rapid urbanization and accompanying lifestyle changes in India lead to transition in non-communicable disease risk factors. A survey was done in urban, urban slum and rural population of Haryana, India, in a sample of 4129 men and 3852 women using WHO STEPS questionnaire. A very high proportion of all the three populations reported inadequate intake of fruits and vegetables. Rural men reported five times physical activity as compared with urban and urban slum men and rural women reported seven times physical activity as compared with women in the other two settings. Mean body mass index (BMI) was highest among urban men (22.8 kg m(-2)) followed by urban slum (21.0 kg m(-2)) and rural men (20.6 kg m(-2)) (P-value < 0.01). Similar trend was seen for women but at a higher level than men. Prevalence of obesity (BMI >/= 30 kg m(-2)) was highest for urban population (male = 5.5%, female = 12.6%) followed by urban slum (male = 1.9%, female = 7.2%) and rural populations (male = 1.6%, female = 3.8%). Urbanization increases the prevalence of the studied non-communicable disease risk factors, with women showing a greater increase as compared with men. Non-communicable disease control strategy needs to address urbanization and warrants gender sensitive strategies specifically targeting women.

Abstract
Activity-dependent synapse reduction is a major determinant of neuromuscular innervation. Previous research has shown that nanomolar concentrations of hirudin, a specific thrombin antagonist, significantly attenuates this reduction, and protease nexin 1 (PN1), an endogenous thrombin inhibitor closely localized to the neuromuscular synapse, can inhibit synapse reduction at similar concentrations. Protease inhibitors which do not inhibit thrombin, including cystatin and aprotinin, had no effect on synapse reduction. We present a series of experiments examining whether prothrombin and/or PN1 gene expression, as well as thrombin activity, are regulated in muscle cultures by acetylcholine (ACh) receptor activation. We also studied the effect of exogenous thrombin on synapse elimination in co-cultures of muscle and cholinergic neurons. Cultured muscle cells were electrically blocked with tetrodotoxin (TTX), or co-treated with ACh in order to isolate ACh receptor activation. Electrical blockade resulted in a decrease in thrombin release to about two-thirds of control values. The application of ACh to electrically blocked muscle cultures resulted in a 2.5-fold increase in thrombin activity released into the medium and a 2-fold increase in prothrombin gene expression. In contrast, ACh treatment in the presence of TTX had no effect on PN1 gene expression compared to treatment with TTX alone. In addition, exogenous thrombin significantly increased synapse elimination in unstimulated muscle/cholinergic neuron co-cultures. These results suggest that thrombin or a thrombin-like molecule released from muscle is required for activity-dependent synapse elimination and is regulated by neuromuscular activity.

Abstract
An infant with intussusception who developed an unusual complication of transanal and intraperitoneal prolapse is reported. Complete venous occlusion of the intussusceptum for a prolonged period in a patient with congenital anomalous vascular supply of the colon is suggested as a mechanism responsible for rupture of the intussuscepiens.
