    Lepcha is the oldest and the first tribe reported from Sikkim, India; majority of its population inhabiting in Dzongu valley, an officially demarcated reserve for Lepcha community, bordering Khangchendzonga Biosphere Reserve, in north district. Lepchas of Dzongu are known for their retention of rich cultural heritage. In view of the on-going cultural and economic changes brought in by the process of globalization, the immediate need was felt to document in details the under-explored ethnomedicinal practices of Lepchas of Dzongu valley. This paper reports 118 species, belonging to 71 families and 108 genera, under ethnomedicinal utility by the Lepchas for curing approximately 66 ailments, which could be grouped under 14 broad categories. Zingiberaceae appeared as the most used family (8 species and 5 genera). As per use pattern, maximum of 30.50% species are to cure stomach related disorders/ailments, followed by 19.49% for curing cut, wounds, inflammation, sprains and joint pains. Administration of medicine orally is recorded in 75% cases. Root and rhizome harvesting targeted 30 species. The changing scenario over time both at socio-cultural front and passing traditional knowledge interests from older to younger generation and rich ethnomicinal wealth of the oldest tribe of Sikkim are discussed in the light of conservation strategies and techniques to adopt.

    Background & objectives: Occurrence of chronic physical pain is increasingly identified among youth, and medically unsupervised analgesic use is a possible risk factor for opioid dependence and other mental diseases in later life. Therefore, the present study was carried out in young student population in Sikkim, India, to explore predictors (including current chronic pain and current analgesic use) of low QoL in youth to identify a subset of population vulnerable to substance use and mental diseases in later life. Methods: The study was conducted in a health university setting in Sikkim, North East India. In this cross-sectional study, 156 participants were enrolled with almost equal number of males and females. Generic instruments for demographics and current analgesic use and SF - 36, for assessment of quality of life (QoL), were used. QoL was measured in general, physical and emotional domains. Presence of chronic physical pain during past four weeks was captured using SF - 36. Results: Almost two-third participants reported presence of current physical pain (69%, n=108); and (14%, n=22) reported current analgesic use for pain. In logistic regression model controlled for age, ethnicity, gender and residence, higher body mass index (BMI) (β=-0.16, P=0.02) and current analgesic use (β=1.6, P=0.006) predicted low QoL in emotional domain (less accomplishment due to emotional problem). Current analgesic use also predicted low QoL in another measure of emotional domain (depressed β=2.0, P=0.001). Interpretation & conclusions: This study identified a subset of participants in their youth with low QoL in emotional domain predicted by current analgesic use and possible overweight problem. Low QoL in more than one emotional domain also identifies possibility of later psychiatric impairment. However, chronic pain did not emerge as a significant predictor of low QoL in emotional domain.

    Glacial lake outburst floods (GLOFs) occur when glacier melt water dammed by a moraine is released in short time. Such floods may lead to disastrous events posing, therefore, a huge threat to human lives and infrastructure. A devastating GLOF in Uttarakhand, India, on 17 July 2013 has led to the loss of all villages in a stretch of 18 km downstream the lake and the loss of more than 5000 lives. The present study evaluates all 16 glacial lakes (with an area >0.1 km²) in the Thangu valley, northern Sikkim (India), eastern Himalaya, with respect to potential threats for the downstream areas. The hazard criteria for the study include slope, aspect and distance of the respective parent glacier, change in the lake area, dam characteristics and lake depth. For the most hazardous lakes, the socio-economic conditions in the downstream areas (settlements and infrastructure) are analysed regarding the impact of potential GLOFs. For the vulnerability analysis, we used various satellite products including LANDSAT, RESOUCESAT-1 and 2, RISAT-1 imageries and ASTER GDEM covering the period from 1977 to 2014. For lake mapping, we applied the Normalized Difference Vegetation Index (NDVI) and the Normalized Difference Snow Index (NDSI). A Land Use Land Cover (LULC) map of the study area showing in-situ observations is serving as driving factor for the vulnerability analysis. The results of the study show that almost all evaluated glacial lakes were expanding during the study period (1977-2014). Combining the hazard criteria for the lakes, 5 of the 16 studied glacial lakes are identified as highly hazardous. In the downstream area, there are two villages with 200 inhabitants and an army camp within the zone of highest vulnerability. The identified vulnerability zones may be used by the local authorities to take caution of the threatened villages and infrastructure and for risk analysis for planned future hydropower plants.

    Sikkim is emerging as an important area for prescription opioid abuse with frequent news of seizures and arrests due to possession of prescription opioids. However, till date there is a little information on descriptive epidemiology and high risk behavior of prescription opioid abusers from Sikkim. The aim was to describe demographic (age, sex, religion, marital status, community, occupation, etc.); socioeconomic (income, education, family information etc.); and high risk behavior (e.g., injection sharing, visit to commercial sex workers [CSWs], homosexuality etc.) among treatment-seeking prescription opioid abusers in Sikkim. Epidemiological data were collected by administering predevised questionnaires from n = 223 prescription opioid abusers (main problem prescription opioids) reporting for treatment at five different drug abuse treatment centers across Sikkim. The mean age of prescription opioid abusers in Sikkim was 27 years; all were male, of Nepalese ethnicity and single/never married, school dropout and/or illiterate, earning < Rs. 10,000/month with most spending almost Rs. 5000 a month on prescription opioids. Most (57.4%) prescription opioid abusers belonged to the urban community. Commonly abused prescription opioids were dextropropoxyphene and codeine. Injection sharing was more in urban areas whereas syringe exchange was observed equally among rural and urban prescription opioid abusers. Among urban injectors visits to CSWs, and multiple sex partners were also common in spite of knowledge about AIDS. Limited condom use was observed among rural respondents. Incidences of arrests, public intoxication, and violence under the influence of prescription opioids were also reported. Both the rural and urban areas of Sikkim show increasing rates of prescription opioid abuse among males. It is more prevalent among school dropouts and unemployed youth. Trends of injection drug use, unsafe injection, high risk behavior have also been observed.

    Sikkim, a tiny Himalayan state situated in the north-eastern region of India, records limited research on the climate change. Understanding the changes in climate based on the perceptions of local communities can provide important insights for the preparedness against the unprecedented consequences of climate change. A total of 228 households in 12 different villages of Sikkim, India, were interviewed using eight climate change indicators. The results from the public opinions showed a significant increase in temperature compared to a decade earlier, winters are getting warmer, water springs are drying up, change in concept of spring-water recharge (locally known as Mul Phutnu), changes in spring season, low crop yields, incidences of mosquitoes during winter, and decrease in rainfall in last 10 years. In addition, study also showed significant positive correlations of increase in temperature with other climate change indicators viz. spring-water recharge concept (R (2) = 0.893), warmer winter (R (2) = 0.839), drying up of water springs (R (2) = 0.76), changes in spring season (R (2) = 0.68), low crop yields (R (2) = 0.68), decrease in rainfall (R (2) = 0.63), and incidences of mosquitoes in winter (R (2) = 0.50). The air temperature for two meteorological stations of Sikkim indicated statistically significant increasing trend in mean minimum temperature and mean minimum winter temperature (DJF). The observed climate change is consistent with the people perceptions. This information can help in planning specific adaptation strategies to cope with the impacts of climate change by framing village-level action plan.

    A third of the world rabies burden is in India. The Sikkim Anti-Rabies and Animal Health (SARAH) program is the first state-wide rabies program in India and demonstrates a successful One Health model of dog-mediated rabies elimination. The SARAH program was created in 2006 as a collaboration between the Government of Sikkim and international non-government organizations—Vets Beyond Borders and Fondation Brigitte Bardot. Activities are directed to canine rabies vaccination, humane dog population control, community education, and treatment of sick and injured animals. In 2005, there were 0.74 human rabies deaths per 100,000 (4 deaths) within Sikkim, and from 2006 to 2015, there were no human rabies deaths. In 2016, two human rabies deaths were reported near the West Bengal border region. From 2005 to 2010, the incidence of animal rabies is unknown; from 2010 to 2016, eight cases of animal rabies were reported. Major challenges for the program are continued commitment to rabies control in the face of 0 to low human rabies incidence and the risk of rabies incursions. Effective intersectoral communication between Health, Veterinary, Forestry, and Police officers is essential to enable rapid response to animal bite incidents and possible rabies incursions. An integrated One Health approach needs to be maintained with enhanced active rabies surveillance. Other states must establish similar programs if India is ever to achieve a goal of eliminating dog-mediated human rabies. PMID:28361056

    The Khangchendzonga National Park is a part of the eastern Himalaya global biodiversity hotspot and is located in the Sikkim state of India. Increasing livestock populations coupled with the government policy to ban grazing and its selective implementation resulted in conflict. Hence we undertook this multidisciplinary study involving consultations with traditional resource users, field surveys, and remote sensing. We found that in the greater Himalayan part, over the past 6 decades sheep have been increasingly replaced by yaks (and their crossbreeds), who descend only up to the multilayered temperate and subalpine forests during winter. These forests have been extensively manipulated by the yak herders to increase the fodder availability. In terms of economics and equity in benefit sharing, we found that a few yak herders earn high incomes by maintaining large herds while the sheep and pack animal herders earn subsistence level incomes from small herds. We propose a reduction in yak (and their female crossbreed) numbers with adequate alternative livelihood support for the herders.

    Background: Psychological stress following natural disaster is common. Despite several earthquakes in India, data on evaluation of acute stress among the child victims in the early postdisaster period is scarce. Immediately following a devastating earthquake (6.9 Richter) at Sikkim on September, 18 2011, many children attended North Bengal Medical College, the nearest government tertiary care institution, with unusual stress symptoms. Objective: Evaluation of acute stress symptoms in children in the immediate postearthquake period. Materials and Methods: This was a cross-sectional study done over 4 weeks and includes all the children from 1 to 12 years presenting with unusual physical or behavioral symptoms. Those with major injuries requiring admission were excluded. They were divided into two age groups. For older children (8-12 years) the 8-item Children Impact of Event Scale (CIES) was used for screening of stress. Unusual symptoms were recorded in younger children (1-8 years) as CIES is not validated < 8 years. Result: A total of 84 children (2.66%) out of 3154 had stress symptoms. Maximum attendance was noted in first 3 days (65.47%) and declined gradually. In children ≥ 8 years, 48.78% had psychological stress, which was statistically significant on CIES scores without any gender predilection. Static posturing (41.86%), sleeplessness (32.55%), anorexia (9.30%), recurrent vomiting (13.95%), excessive crying (13.95%), or night-awakenings (4.65%) were found in younger children (n = 43) and three required admission. Conclusion: This study represent the first Indian data showing statistically significant psychological impact in older children (8-12 years) and various forms of physical stress symptoms in young children (1-8 years) following earthquake.

    2015-09-01

    This paper presents a macro-level seismic landslide hazard assessment for the entire state of Sikkim, India, based on the Newmark's methodology. The slope map of Sikkim was derived from ASTER Global Digital Elevation Model (GDEM). Seismic shaking in terms of peak horizontal acceleration (PHA) at bedrock level was estimated from deterministic seismic hazard analysis (DSHA), considering point source model. Peak horizontal acceleration at the surface level for the study area was estimated based on nonlinear site amplification technique, considering B-type NEHRP site class. The PHA at surface was considered to induce driving forces on slopes, thus causing landslides. Knowing the surface level PHA and slope angle, the seismic landslide hazard assessment for each grid point was carried out using Newmark's analysis. The critical static factor of safety required to resist landslide for the PHA (obtained from deterministic analysis) was evaluated and its spatial variation throughout the study area is presented. For any slope in the study area, if the in-situ (available) static factor of safety is greater than the static factor of safety required to resist landslide as predicted in the present study, that slope is considered to be safe.

    The Tista River, a major tributary of the Brahmaputra drainage system (Eastern Himalaya) has built a fluvial deposit which extents over 16500 km2. The Tista megafan stands out because of (1) its disproportionate size compared to that of the upstream Tista River catchment (8000 km2), and (2) it has been incised about 50m by the river at the topographic front of the mountain range. Neither the timing of deposition/incision of the megafan sediments, and their potential tectonic or climatic controls have yet been investigated. We use both IRSL and 10Be cosmogenic data to respectively constrain the date of deposition and abandonment of the different lobes of the megafan. We suggest that two distal lobes developed successively downstream from a common proximal lobe. Deposition took place since ~50 ka and incision began at 4.0 +0.6/-0.4 ka at an average rate of 10.5 +0.6/-1.8 mm yr-1. In addition, petrology, isotope geochemistry (ɛNd, 87Sr/86Sr) and chemical composition performed on modern river sands and late-Quaternary megafan sediments allows characterizing (1) provenance variations through time of megafan deposits and their implication for drainage development (2) the weathering history of Sikkim recorded by the megafan deposits. Results show that the Tista fan deposits are mainly sourced from the High Himalayan Crystalline domain and the Tethyan Sedimentary Series, (consistent with high erosion rates identified in north Sikkim at millennial timescale). Variations in provenance and weathering through time recorded by the Tista megafan deposits can be linked to climatic variations with strong monsoonal precipitations penetrating further northward into the southern Tibetan plateau. Tectonic processes seem to play a minor role. Otherwise, we propose as a first hypothesis that the Kosi River has recently (at ~4 ka) captured the upper part of the Tista catchment. That could explain the particular isotopic signature of the Tista megafan deposits, its recent incision, its

    The Darjeeling-Sikkim Himalaya lies in the eastern part of the Himalayan fold-thrust belt (FTB) in a zone of high arc-perpendicular convergence between the Indian and Eurasian plates. In this region two distinct faults form the Main Central thrust (MCT), the structurally higher MCT1 and the lower MCT2; both these faults have translated the Greater Himalayan hanging wall rocks farther towards the foreland than in the western Himalaya. The width of the sub-MCT Lesser Himalayan rocks progressively decreases from the western Himalaya to this part of the eastern Himalaya, and as a result, the width of the FTB is narrower in this region compared to the western Himalaya. Our structural analysis shows that in the Darjeeling-Sikkim Himalaya the sub-MCT Lesser Himalayan duplex is composed of two duplex systems and has a more complex geometry than in the rest of the Himalayan fold-thrust belt. The structurally higher Dating duplex is a hinterland-dipping duplex; the structurally lower Rangit duplex varies in geometry from a hinterland-dipping duplex in the north to an antiformal stack in the middle and a foreland-dipping duplex in the south. The MCT2 is the roof thrust of the Daling duplex and the Ramgarh thrust is the roof thrust of the Rangit duplex. In this region, the Ramgarh thrust has a complex structural history with continued reactivation during footwall imbrication. The foreland-dipping component of the Rangit duplex, along with the large displacement associated with the reactivation of the Ramgarh thrust accounts for the large translation of the MCT sheets in the Darjeeling-Sikkim Himalaya. The growth of the Lesser Himalayan duplex modified the final geometry of the overlying MCT sheets, resulting in a plunge culmination that manifests itself as a broad N-S trending "anticline" in the Darjeeling-Sikkim Himalaya. This is not a "river anticline" as its trace lies west of the Teesta river. A transport parallel balanced cross section across this region has accommodated

    The present study investigates the prevalence of reproductive health morbidities, treatment-seeking behavior, and its association with sociodemographic correlates among unmarried and married adolescent girls of Sikkim. The study sample includes 1250 adolescent girls randomly selected from both urban and rural blocks of the State. Information on socioeconomic and demographic characteristics, prevalence of reproductive health morbidities, and treatment-seeking behavior was collected using standard pretested questionnaires. of the study indicate that the prevalence of reproductive health morbidities among both married and unmarried girls is quite high. Age, media exposure, and economic status emerged as significant correlates of treatment-seeking practices among both married and unmarried girls. High prevalence of reproductive health morbidity in this vulnerable group, particularly in rural settings, requires urgent intervention of health planners. This study reinforces an indirect and mediatory role of socioeconomic and demographic factors in the prevalence of reproductive health morbidities and associated treatment-seeking behaviors.

    Understanding the relative strengths of tectonic and climatic forcing on erosion at different spatial and temporal scales is important to understand the evolution of orogenic topography. To address this question, we quantified exhumation rates at geological timescales and erosion rates at millennial timescales in modern river sands from 10 sub-catchments of the Tista River drainage basin in the Sikkim Himalaya (northeast India) using detrital apatite fission-track thermochronology and cosmogenic 10Be analyses, respectively. We compare these rates to several potential geomorphic or climatic forcing parameters. Our results show that millennial erosion rates are generally higher and spatially more variable than long-term exhumation rates in Sikkim. They also show strongly contrasting spatial patterns, suggesting that the processes controlling these rates are decoupled. At geological timescales, exhumation rates decrease from south to north, with rates up to 1.2 ± 0.6 mm/yr recorded in southwest Sikkim and as low as 0.5 ± 0.2 mm/yr in the northernmost catchment. Long-term exhumation rates do not correlate with any geomorphic or climatic parameter. We suggest they are tectonically controlled: high rates in southwest Sikkim may be linked to the building of the Lesser Himalaya Rangit Duplex, whereas low rates in north Sikkim are consistent with cessation of extensional exhumation along the South Tibetan Detachment after 13 Ma. The highest apparent erosion rates recorded by cosmogenic nuclides (∼5 mm/yr) occur in catchments spanning the Main Central Thrust Zone, but these appear to be strongly influenced by recent landsliding. High millennial erosion rates (1-2 mm/yr) also occur in north Sikkim and may be climatically driven through strong glacial inheritance of the landscape, as attested by high channel-steepness values close to the maximum extent of glaciers during the Last Glacial Maximum. In contrast, variations in rainfall rate do not seem to strongly influence

    Objective To assess the knowledge, attitude and practice of contraception among the college students. Materials and Methods A cross sectional study was conducted in the Government College, Gangtok, Sikkim, during the month of April 2009 to evaluate the knowledge, attitude and practice of contraception among 156 students enrolled in the first year bachelor course. Descriptive statistics was used for data analysis. Results 98% (153/156) of the students had knowledge about family planning and 86% (134/156) of them had heard about contraceptives. Most of them knew about condoms (85%) and contraceptive pills (40%) but knowledge about permanent methods and Cu-T was poor (average 12%). Most students thought contraceptives were to be used to prevent unwanted pregnancy (35%) and for birth spacing (30%). 11% of students had used some form of contraceptive in the past and 7% were currently users. The most commonly used contraceptives were condoms, followed by combined use of OCP and condom. Conclusion The study highlights the need to motivate the youth for effective and appropriate use of contraceptives when required and arrest the trend towards unwanted pregnancy. PMID:24591903

    2005-07-01

    In the Sikkim Himalaya, an enormous variety of wild growing plants are exploited at large scale for collection of their edible parts, of which six most prominently utilized fruit species (viz., Baccaurea sapida, Diploknema butyracea, Elaeagnus latifolia, Eriolobus indica, Machilus edulis and Spondias axillaris) were investigated. The growth of nursery raised seedlings was measured at 3 month intervals until two years old in terms of absolute growth rate (AGR), relative growth rate (RGR), net assimilation rate (NAR), leaf area ratio (LAR), leaf weight ratio (LWR), stem weight ratio (SWR), root weight ratio (RWR) and root-shoot ratio (RSR). Spondias axillaris and Machilus edulis had the maximum AGR, RGR, LAR and SWR among all species. LWR was highest for B. sapida. RGR, LAR and LWR declined with the age of seedlings. RGR was negatively correlated with NAR, SWR, RWR and RSR, though it showed a positive relationship with LAR. For all species, seedlings attained significant sizes after one year of age, and showed reasonable survival after transplantation into the farmers' fields. It is expected that information on the growth behaviour of these species would be useful while they are adopted into agroforestry systems. It is suggested that these species should be multiplied at large scale and distributed to the local inhabitants to reduce pressure on them in natural stands as well as provide economic benefit to the subsistence farmers.

    Objective: The present study had been undertaken to investigate the sociodemographic profile of individuals who had committed suicide in Sikkim which may throw light on the vulnerable groups. Materials and Methods: Ten-year suicide data (2006–2015) obtained from Police Headquarters, Crime Branch, Gangtok, have been statistically evaluated to study the sociodemographic profile. Results: The results showed that out of 1604 suicide cases recorded for the past 10 years, 1051 were males (65.5%) and 553 (34.5%) were females. Suicide was found to be common among the age group of 21–30 years (24.4%), Rai community (15.8%), population of rural areas (82.6%), and among the population of eastern districts (50.6%). Hanging (94.8%) was found to be the most common method adopted for suicide. Conclusion: The study provides preliminary information about the vulnerable groups for suicide in the state which may be vital for taking necessary steps for its prevention shortly. PMID:28197004

    The Main Central Thrust (MCT) is a prominent continental-scale fault within the Himalaya. Its definition has been the topic of some debate in the literature. After a brief consideration of the state of discussion to clarify the definition we use in this work, we report features from the field- to the microstructural- scale of a particularly well-exposed section in Sikkim, NE India. The nature of the protoliths as well as the overlying and underlying rocks is characterized in terms of ε-Nd. The dates of motion on the fault are constrained using U-Pb geochronology of zircon and monazite from pegmatitic dikes that cross-cut the deformation fabric. It is found that the mechanism of deformation recorded in the fault zone rocks is different compared to that found in the overlying Greater Himalayan (GH) or the underlying Lesser Himalayan (LH) rocks. The GH and LH have different protolith characteristics as well. Combined with existing data on P-T history, dates of metamorphism, and cooling- and exhumation-rates of the GH and the LH, our measurements show that major motion on this fault occurred before 20 Ma at 450-700 °C but after peak metamorphism of rocks (750-800 °C) in this zone. Isolated events occurred in this zone as late as 11 Ma, possibly in the brittle domain. This underscores the pulsed nature of movement over an extended period on such major faults, and the related difficulties in dating fault movement, determination of the rates of movement, and designating a fault plane as in- or out-of-sequence within a propagating deformation front.

  20. Diverse Diurnal and Seasonal Sapflux Responses in Three Co-occurring Species from East Himalayan Wet Temperate Forests in Sikkim Himalaya, India

    In a first attempt from Eastern Himalaya, we investigate diurnal and seasonal variability in transpiration by three dominant co-occurring species, Symplocos sps (SYP), Eurya sps (EU) & Castanopsis sps (CNP) from a regenerating East-Himalyan wet temperate forest stand located at 2150 amsl in the Fambonglho Wildlife Sanctuary in Sikkim, India. We installed 13 trees (5 SYP, 5 EU & 3 CNP) with Granier's thermal dissipation method (TDM)-based sapflow sensors (different depths of sapwood in one tree of each species for radial sapflow profile and at 2ndcm depth for remaining trees) for the dry season from November 2013 - May 2014. Environmental variables like temperature, relative humidity, soil water potential, rainfall and streamflow were measured using dataloggers-based sensors. Radially, SYP and EU showed higher sapflux density (SFD) in the outer xylem, whereas CNP had highest SFD near the inner xylem. Diurnally, both SYP and EU exhibited bi-modal peaks (early-morning and late-afternoon) during the moist months, and unimodal peaks (noon) in the relatively drier months; indicating probable controls of soil moisture on transpiration. CNP showed only unimodal peak (noon). Higher SFD was observed at the sensor placed on the north-facing side, across all species, indicating circumferential variability. As the dry season progressed, SYP and EU exhibited decreasing transpiration, whereas Castnopsis showed consistently high rates (probably due to deeper rooting depths). Discrete weighted-mean method was used calculating whole-tree sapflow in the trees with depth sensors. Results suggest that SYP and EU exhibit similar transpiration characteristics possibly due their similar eco-physiological traits (secondary species); in contrast to CNP (canopy species). CNP showed relatively higher sapflow than reported from Central Himalaya, indicative of evolution under a relatively wetter climate. Vapour pressure deficit and solar radiation act as drivers of transpiration, which seems to

    The High Himalayan Crystallines (HHCs) provide an excellent natural laboratory to study processes related to crustal melting, crustal differentiation, and the tectonic evolution of mountain belts because partial melting in these rocks occurred under well-defined tectonic boundary conditions (N-S collision of the Indian and the Eurasian plates) and the rocks have not been modified by subsequent metamorphic overprinting. We have used petrogenetic grids, kinetically constrained individual thermobarometry, pseudosection calculations, and reaction histories constrained by textural evidence to determine that the migmatites in the HHC of Sikkim attained peak P-T conditions of 750-800 °C, 9-12 kbar, followed by steep isothermal decompression to 3-5 kbar, and then isobaric cooling to ~600 °C. There may be a trend where rocks to the north [closer to the South Tibetan detachment system (STDS)] attained somewhat higher maximum pressures. The decompression may have been triggered by a reduction in density due to the production of melt (~20 vol%); minor amounts of additional melt may have been produced in individual packages of rock during decompression itself, depending on the exact geometry of the P-T path and the bulk composition of the rock. The stalling of rapid, isothermal exhumation at depths of 10-18 km (3-5 kbar) is related to metamorphic reactions that occur in these rocks. Geospeedometry indicates that at least a two-stage cooling history is required to describe the compositional zoning in all garnets. Both of these stages are rapid (several 100's °C/my between 800 and 600 °C, followed by several 10's °C/my between 600 and 500 °C), but there appears to be a spatial discontinuity in cooling history: Rocks to the south (closer to main central thrust) cooled more slowly than rocks to the north (closer to STDS). The boundary between these domains coincides with the discontinuity in age found in the same area by Rubatto et al. (Contrib Mineral Petrol 165

    For the foreseeable future, the search for evidence of past life in rocks acquired from other planets will be constrained by the amount of sample available and by the fidelity of preservation of any fossils present. What amount of rock is needed to establish the existence of past life? To address this question, we studied a minute amount of rock collected from cherty dolomites of the Proterozoic Buxa Formation in the metamorphically altered tectonically active northeastern Himalaya. In particular, we investigated 2 small petrographic thin sections-one from each of 2 bedded chert horizons exposed in the Ranjit River stratigraphic section northwest of Rishi, Sikkim, India-that together comprise an area of approximately 5 cm(2) (about the size of a US postage stamp) and have a total rock weight of approximately 0.1 g. Optical microscopy, confocal laser scanning microscopy, and Raman spectroscopy and imagery demonstrate that each of the thin sections contains a rich assemblage of 3-dimensionally permineralized organic-walled microfossils. This study, the first report of Proterozoic microfossils in units of the Ranjit tectonic window, demonstrates that firm evidence of early life can be adduced from even a minuscule amount of fossil-bearing ancient rock.

    Autochthonous strains of Saccharomyces cerevisiae from traditional starters used for the production of rice-based ethnic fermented beverage in North East India were examined for their genetic polymorphism using mitochondrial DNA-RFLP and electrophoretic karyotyping. Mitochondrial DNA-RFLP analysis of S. cerevisiae strains with similar technological origins from hamei starter of Manipur and marcha starter of Sikkim revealed widely separated clusters based on their geographical origin. Electrophoretic karyotyping showed high polymorphism amongst the hamei strains within similar mitochondrial DNA-RFLP cluster and one unique karyotype of marcha strain was widely distributed in the Sikkim-Himalayan region. We conceptualized the possibility of separate domestication events for hamei strains in Manipur (located in the Indo-Burma biodiversity hotspot) and marcha strains in Sikkim (located in Himalayan biodiversity hotspot), as a consequence of less homogeneity in the genomic structure between these two groups, their clear separation being based on geographical origin, but not on technological origin and low strain level diversity within each group. The molecular markers developed based on HinfI-mtDNA-RFLP profile and the chromosomal doublets in chromosome VIII position of Sikkim-Himalayan strains could be effectively used as geographical markers for authenticating the above starter strains and differentiating them from other commercial strains.

    Natural and human causes of change in land use and soil properties were studied in the Sikkim Himalayas piedmont over the last 150 years, with a special emphasis on the period 1930-2010. Analysis of historical reports, combined with the visual interpretation of topographic maps and satellite images, indicates that the land reforms related to the location of tea gardens caused rapid deforestation of the higher elevated terraces in the late 19th century. Continuous population growth between 1930 and 2010 caused a shift in the major land use changes from the terraces to the floodplains. As a consequence, a gradual extension of tea plantation and forestry development helped in stabilizing the land use of the terraces, while the parallel deforestation of mountain catchments and floodplains for rice cultivation intensified fluvial activity. The enlargement of river-channel area by about 42% between 1930 and 2010 excluded a large part of the floodplains from cultivation and increased risk of soil degradation. The replacement of natural forest by monocultural tea and rice cultivation influenced the physical and chemical properties of the soil. Statistically significant changes were observed only in some chemical properties of the topsoil. Tea cultivation reduced the total carbon content by 26% and total nitrogen content by 33% in the surface soil horizon. The influence of rice tillage on the soil properties is masked by the fluvial activity. The combined effect of flooding and rice cultivation is reflected in the lower content of total carbon and nitrogen in the surface of the soil, namely, 76% and 77% respectively. Taking into account the long-term nature of the plantation, the soil still has the capability to support tea production. The productivity of rice depends partly on fertilization levels and partly on the natural deposition of fresh sediment eroded from mountains.

    The North-eastern (NE) India, comprising of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura, possess diverse array of locally adapted non-Basmati aromatic germplasm. The germplasm collections from this region could serve as valuable resources in breeding for abiotic stress tolerance, grain yield and cooking/eating quality. To utilize such collections, however, breeders need information about the extent and distribution of genetic diversity present within collections. In this study, we report the result of population genetic analysis of 107 aromatic and quality rice accessions collected from different parts of NE India, as well as classified these accessions in the context of a set of structured global rice cultivars. A total of 322 alleles were amplified by 40 simple sequence repeat (SSR) markers with an average of 8.03 alleles per locus. Average gene diversity was 0.67. Population structure analysis revealed that NE Indian aromatic rice can be subdivided into three genetically distinct population clusters: P1, joha rice accessions from Assam, tai rices from Mizoram and those from Sikkim; P2, aromatic rice accessions from Nagaland; and P3, chakhao rice germplasm from Manipur [corrected]. Pair-wise FST between three groups varied from 0.223 (P1 vs P2) to 0.453 (P2 vs P3). With reference to the global classification of rice cultivars, two major groups (Indica and Japonica) were identified in NE Indian germplasm. The aromatic accessions from Assam, Manipur and Sikkim were assigned to the Indica group, while the accessions from Nagaland exhibited close association with Japonica. The tai accessions of Mizoram along with few chakhao accessions collected from the hill districts of Manipur were identified as admixed. The results highlight the importance of regional genetic studies for understanding diversification of aromatic rice in India. The data also suggest that there is scope for exploiting the genetic diversity of aromatic and

    Culicoides orientalis was first recorded from Sikkim, in the year 1963, but no evidence based disease outbreak were available. In the last 50 years, 260 Bluetongue disease outbreaks caused by Culicoides species have been evidenced from India. Moreover, in recent years with increase of average temperature worldwide and increase in longevity of arthropod vectors like Culicoides along with a geographical range shift to new suitable warmer regions has increased the potentiality of vector borne disease outbreak throughout the world. The Himalayan range of Sikkim in India is a biodiversity hotspot and is extremely sensitive to such global climate changes. An attempt has been made to evaluate the altitude, climate and environmental data on selected study sites of Sikkim for a period of two years (2014-2015) for discerning potential distribution of C.orientalis in this region. The altitude, temperature, precipitation and potential distribution range maps of C. orientalis showed the areas of highest species abundance within the altitudinal range of 550-1830m, with some species extending its range up to 3750m, with average precipitation of 2010-2590mm and mean temperature of 11-18°C. The Maximum Entropy Modelling (MaxEnt) and the Jackknife test of the MaxEnt model further revealed that the major contributing factors governing C. orientalis distribution are annual precipitation (78.8%), followed by precipitation of driest quarter (8.3%) and mean temperature of the warmest quarter (3.3%). Accuracy of the study was evaluated by the area under the curve (AUC=0.860). The Biplot on F1-F2 axes (N=16, α=0.05) in the PCA showed the linear depiction of all the variables considered in our study, major contributors were annual precipitation, precipitation of driest quarter and mean temperature of warmest quarter being the primary factors governing species distribution, as analogous to results of the MaxEnt model.

    Background Due to the difficult geographic terrain with lack of roads and transport, the Sikkim State in India finds difficulties in contending the respiratory diseases especially during the rainy seasons. Findings A case–control study was conducted for two months at the Central Referral Hospital of East Sikkim involving 110 individuals in the age group of 10 years and above. Due to feasibility constraints, 55 cases and 55 controls were selected by applying the non-probability sampling method with age and sex matching. The collected data were tabulated and analyzed by using the SPSS (Statistical Package for Social Sciences) version 10.0 for windows. Findings were expressed in terms of proportion, Chi Square Test and Multiple Logistic Regression Analysis. Here, p-value <0.05 was considered as statistically significant. This study revealed that the presence of overcrowding, chronic exposure to allergens, smoking habits, chronic respiratory illnesses within last 5 years, family history of chronic respiratory illnesses and mental illnesses were independently associated with respiratory diseases. Conclusion This study should be replicated in other parts of Sikkim to obtain more confirmatory evidence on determinants of respiratory diseases. PMID:24010571

    Cordyceps sinensis has been described as a medicine in old Chinese medical books and Tibetan medicine. It is a rare combination of a caterpillar and a fungus and found at altitudes above 4500m in Sikkim. Traditional healers and local people of North Sikkim recommend the mushroom, i.e., Yarsa gumba, Keera jhar (C. sinensis) for all diseases either as a single drug or combined with other herbs. The present study was undertaken to collect information regarding the traditional uses of cordyceps in Sikkim. It was found that most local folk healers/traditional healers use cordyceps for the treatment of 21 ailments. A modern literature search was carried out to assess whether the curative effects are valid or just blind faith of local people. Chemical constituents of cordyceps are given and pharmacological and biological studies reviewed. More mechanism-based and disease-oriented clinical studies are recommended. PMID:21731381

    One of the enduring debates in the study of the Himalayan orogen (and continental collision zones in general) is whether the salient observed features are explained (a) by localized deformation along discrete, narrow fault zones/ductile shear zones separating individual blocks or slices (e.g. critical taper or wedge tectonic models), or (b) by distributed deformation dominated by wide zones of visco-plastic flow in the solid or a partially molten state (e.g. channel flow models). A balanced cross-section from Sikkim in the eastern Himalaya that is based on structural data and is drawn to satisfy petrological and geophysical constraints as well, is used in combination with information from petrology, geochronology, geospeedometry and microstructural data to address this question. We discuss that any tectonic model needs to be thermally, rheologically, geometrically and temporally viable in order to qualify as a suitable description of a system; models such as channel flow and critical taper are considered in this context. It is shown that channel flow models may operate with or without an erosional porthole (channel with tunnel and funnel mode vs. channels with only the tunnel mode) and that the predicted features differ significantly between the two. Subsequently, we consider a large body of data from Sikkim to show that a channel flow type model (in the tunneling without funneling mode), such as the ones of Faccenda et al. (2008), describes features formed at high temperatures very well, while features formed at lower temperatures are more consistent with the operation of localized, fault-bounded, slice tectonics, (LFBST, be it in the form of critical taper, wedge tectonics, or something else). Thus, the two modes are not competing, but collaborating, processes and both affect a given rock unit at different points of time during burial, metamorphism and exhumation. A transitional stage separates the two end-member styles of tectonic evolution. The proposed models

    On September 18, 2011 an earthquake of 6.8 magnitude on the Richter scale struck Sikkim at 18.11 hours IST. The epicenter of the quake was latidude 27.7o North and longitude 88.2o East about 64 km North-West of Gangtok along the junction point of Teesta lineament and Kanchenjunga fault in the North District of Sikkim. The high intensity tremor triggered various types of natural calamities in the form of landslides, road blocks, falling boulders, lake bursts, flash floods, falling of trees, etc. and caused severe damage to life and property of the people in Sikkim. As the earthquake occurred during the monsoon season, heavy rain and landslides rendered rescue operations extremely difficult. Almost all road connectivity and communication network were disrupted. Sikkim experiences landslides year after year, especially during the monsoons and periods of intense rain. This hazard affects the economy of the State very badly. But due to the earthquake, many new and a few reactivated landslides have occurred in the Sikkim Himalaya.

    Ancient medical systems are still prevalent in Sikkim, popularly nurtured by Buddhist groups using the traditional Tibetan pharmacopoeia overlapping with Ayurvedic medicine. Traditional medical practices and their associated cultural values are based round Sikkim’s three major communities, Lepcha, Bhutia and Nepalis. In this study, a semi-structured questionnaire was prepared for folk healers covering age and sex, educational qualification, source of knowledge, types of practices, experience and generation of practice, and transformation of knowledge. These were administered to forty-eight folk healers identified in different parts of Sikkim. 490 medicinal plants find their habitats in Sikkim because of its large variations in altitude and climate. For 31 commonly used by these folk healers, we present botanical name, family, local name, distribution, and parts used, together with their therapeutic uses, mostly Rheumatoid arthritis, Gout, Gonorrhea, Fever, Viral flu, asthma, Cough and Cold, indigestion, Jaundice etc. A case treated by a folk healer is also recounted. This study indicates that, in the studied area, Sikkim’s health traditions and folk practices are declining due to shifts in socio-economic patterns, and unwillingness of the younger generation to adopt folk healing as a profession.

    Educational initiatives targeting at-risk populations have long been recognized as a mainstay of ongoing rabies control efforts. Cluster-based studies are often utilized to assess levels of knowledge, attitudes and practices of a population in response to education campaigns. The design of cluster-based studies requires estimates of intra-cluster correlation coefficients obtained from previous studies. This study estimates the school-level intra-cluster correlation coefficient (ICC) for rabies knowledge change following an educational intervention program. A cross-sectional survey was conducted with 226 students from 7 schools in Sikkim, India, using cluster sampling. In order to assess knowledge uptake, rabies education sessions with pre- and post-session questionnaires were administered. Paired differences of proportions were estimated for questions answered correctly. A mixed effects logistic regression model was developed to estimate school-level and student-level ICCs and to test for associations between gender, age, school location and educational level. The school- and student-level ICCs for rabies knowledge and awareness were 0.04 (95% CI: 0.01, 0.19) and 0.05 (95% CI: 0.2, 0.09), respectively. These ICCs suggest design effect multipliers of 5.45 schools and 1.05 students per school, will be required when estimating sample sizes and designing future cluster randomized trials. There was a good baseline level of rabies knowledge (mean pre-session score 71%), however, key knowledge gaps were identified in understanding appropriate behavior around scared dogs, potential sources of rabies and how to correctly order post rabies exposure precaution steps. After adjusting for the effect of gender, age, school location and education level, school and individual post-session test scores improved by 19%, with similar performance amongst boys and girls attending schools in urban and rural regions. The proportion of participants that were able to correctly order post

    The Ganga Plain of North India provides an archaeological and skeletal record of semi-nomadic Holocene foragers in association with an aceramic Mesolithic culture. Prior estimates of stature for Mesolithic Lake Cultures (MLC) used inappropriate equations from an American White reference group and need revision. Attention is given to intralimb body proportions and geo-climatic provenance of MLC series in considering the most suitable reference population. Regression equations from ancient Egyptians are used in reconstructing stature for MLC skeletal series from Damdama (DDM), Mahadaha (MDH), and Sarai Nahar Rai (SNR). Mean stature is estimated at between 174 (MDH) and 178 cm (DDM and SNR) for males, and between 163 cm (MDH) and 179 cm (SNR) for females. Stature estimates based on ancient Egyptian equations are significantly shorter (from 3.5 to 7.1 cm shorter in males; from 3.2 to 7.5 cm shorter in females) than estimates using the American White reference group. Revised stature estimates from tibia length and from femur + tibia more accurately estimate MLC stature for two reasons: a) these elements are highly correlated with stature and have lower standard estimates of error, and b) uncertainty regarding methods of measuring tibia length is avoided. When compared with Holocene samples of native Americans and Mesolithic Europeans, MLC series from North India are tall. This aspect of their biological variation confirms earlier assessments and results from the synergistic influence of balanced nutrition from broad-spectrum foraging, body-proportions adapted to a seasonally hot and arid climate, and the functional demands of a mobile, semi-nomadic life-style.

    Edible salt iodization and iodized oil injections are the two most commonly used vehicles for iodine supplementation. In year 1989, the state government of Sikkim was planning to implement Iodine Deficiency Disorder control program in state and had following two options to choose from, based on existing knowledge; a) a salt iodization program, b) an iodized oil injection program. No information was available at that point of time on comparative advantages of the above stated two approaches. To identify the most cost-effective alternative for IDD elimination in Sikkim, amongst the following 3 alternatives: a) Iodized salt program (ISP), b) Iodized oil injection program (IOP) to high risk group, c) no preventive program. Study population was the general population of state of Sikkim, India in year 1990. Cost- effective analysis was undertaken comparing 3 alternative programs, targeted towards IDD elimination in state of Sikkim. Identification, measurement and valuation of the costs of ISP and IOP and identification and measurement of the consequences of IDD were done to carry out the cost-effective analysis. Visible goiter person years (VGPY), endemic cretinism, IDD attributable death were used to assess the health consequences/disease burden of IDD. The cost per VGPY, endemic cretinism and IDD attributable death were Rs 76.67, Rs 24,469 and Rs 9,720, respectively for ISP. The cost per VGPY, endemic cretinism and IDD attributable death were Rs 75.82, Rs 19,106 and Rs 7,709, respectively for IOP. The results of the analysis showed that iodized oil program is more cost-effective for prevention of irreversible IDDs than the iodated salt program in state of Sikkim, India.

    This article reports the results of 100% household injury surveillance project conducted over a 1-year period in nine contiguous villages with a total population of 22,883 persons in north India. Fourteen trained field workers did the health and injury survey by visiting 16-20 households every day. In this article, we document the epidemiology of injuries among children in rural households. A person was considered injured if the injury prevented the victim from continuing a normal daily routine as understood by the family and the victim. A total of 2029 injury cases were recorded. Children in the age group 0-14 years accounted for 611 (30%) of all injury cases of which 42% were injured at home (28% for >14 years), 35% on roads (30% for >14 years), 8% on farms (31% for >14 years) and 6% on playgrounds. The maximum number of injuries was due to falls (35%). Eighty per cent of the injuries were minor (Abbreviated Injury Scale (AIS) 1), 18% were moderate or serious (AIS 2-3); none were severe (AIS 4) and one child had a critical injury (AIS 5). The injury rates per 100,000 children in different age groups were 5354, 6962 and 8060 for 0-4, 5-9 and 10-14 years per year.

    We use data from local earthquakes (mb ≥ 3.0) recorded by the Sikkim broadband seismograph network to study the frequency dependent attenuation of the crust and uppermost mantle. These events have been relocated using body wave phase data from local and regional seismograms. The decay of coda amplitudes at a range of central frequencies (1 to 12 Hz) have been measured for 74 earthquake-receiver pairs. These measurements are combined to estimate the frequency dependent coda Q of the form Q(f) = Q0fη. The estimated Q0 values range from 80-200, with an average of 123±29; and η ranges from 0.92-1.04, with an average of 0.98±0.04. To study the lateral variation of Q0 and η, we regionalized the measured Q values by combining all the earthquake-receiver path measurements through a back projection algorithm. We consider a single back-scatter model for the coda waves with elliptical sampling and parameterize the sampled area using 0.2° square grids. A nine-point spatial smoothening (similar to spatial Gaussian filter) is applied to stabilize the inversion. This is done at every frequency to observe the spatial variation of Q(f) and subsequently combined to obtain η variations. Results of our study reveal that the Sikkim Himalaya is characterized by low Q0 (80-100) compared to the foreland basin to its south (150-200) and the Nepal Himalaya to its west (140-160). The low Q and high η in Sikkim Himalaya is attributed to extrinsic scattering attenuation from structural heterogeneity and active faults within the crust, and intrinsic attenuation due to anelasticity in the hotter lithosphere beneath the actively deforming mountain belt. Similar low Q and high η values had also been observed in North-West and Garhwal-Kumaun Himalaya.

    Sikkim Himalaya are characterised by high altitudinal gradients and greatly varying precipitation patterns, both across space and time, which further influences vegetation distribution and their hydrologic functioning. However, in the absence of long-term and spatially-distributed precipitation data, very little is known about the inherent climatic variability of the region, its impact on the ecosystem complexities and services; and their response to climate change. Recently, satellite rainfall estimates (SREs) have emerged as useful substitute in hydrological studies from Himalayas but require careful validation based on ground observations. In the study, we assess the performance of three gridded SREs TRMM_3B42v7 (TRMM), TRMM_3B42RT v7 (TRMM_RT) & GPM_3IMERGHH v03 (GPM) using ground observations of rainfall and streamflow at Khangchendzonga Bioshpere Reserve in Sikkim, India. TRMM and TRMM_RT were available at 3-hourly temporal resolution and 0.50 spatial resolution, GPM at half-hourly and 0.10; and rainfall from two closely placed tipping bucket raingauges (TBRG) at 1 minute. All datasets were aggregated at 3-hourly, daily and monthly for validation against TBRG. Statistical performance metrics like bias, correlation coefficient, false alarm ration, accuracy etc. were calculated. In a novel approach, hydrograph-based performance assessment (HPA) was carried out by plotting flow data from two nearby streams was as hydrographs using the SREs and TBRG at 3-hourly resolution. Independent categorical assessment of each rainfall source in explaining individual storm events in the streams was done. Statistically, all SREs performed below-par at sub-daily scales (accuracy <0.3) and improved at daily and monthly (accuracy >0.6). Among SREs, TRMM performed the best overall, whereas GPM was better at detecting high-intensity rainfall but poorest at low-intensity rainfall. Both, TRMM and TRMM_RT significantly underestimated rainfall. The performance of SREs based on HPA was

    Hamei and Marcha are mixed dough inocula used as starters for preparation of various indigenous alcoholic beverages in Manipur and Sikkim in India, respectively. These starters are traditionally prepared from rice with wild herbs and spices. Samples of Hamei and Marcha, collected from Manipur and Sikkim, respectively, were analysed for lactic acid bacterial composition. The population of lactic acid bacteria (LAB) was 6.9 and 7.1 Log cfu/g in Hamei and Marcha, respectively. On the basis of phenotypic and genotypic characters, LAB strains isolated from Hamei and Marcha were identified as Pediococcus pentosaceus, Lactobacillus plantarum and Lactobacillus brevis. Technological properties of LAB such as antimicrobial properties, effect on acidification, ability to produce biogenic amines and ethanol, degree of hydrophobicity and enzymatic activities were also performed. Pediococcus pentosaceus HS: B1, isolated from Hamei, was found to produce bacteriocin. None of the strains produced biogenic amines. LAB strains showed a strong acidifying ability and they also produced a wide spectrum of enzymes.

    Collision between the Indian and Eurasian plates since the Eocene (50 Ma) caused the closure of the Neo-Tethys and the underthrusting of India beneath the Tibetan Plateau, generating the 2500 km extended Himalayan belt. The Main Central Thrust (MCT) marks the boundary of the underlying Midland Lower Himalaya metasediments zone (LH) in the south from the overlying high grade metamorphic Higher Himalaya (HH) in the north. Several models considering petrochronology, geothermobarometry and structural geology have been discussed to explain the inverted metamorphic gradient in the LH metasediments without reaching a common agreement. This study investigates the tectonic setting and the timescale of inverted isograds related to crustal-scale thrusting at the MCT in the Sikkim region, northeast India. The aim is to contribute to the understanding of the link between mechanical and thermal evolution of major thrust zones and to clarify the nature and the origin of orogenic heat applying garnet geospeedometry. Garnets provide a sensitive record of metamorphic conditions and are potential chronometer. Their compositional zoning is used as a gauge for rate estimates of element diffusion within the mineral and allows estimating the absolute time of the thermal evolution. Inverse-fitting numerical model considering FRactIonation and Diffusion in GarnEt (FRIDGE) calculates garnet composition profiles by introducing P-T-t paths and bulk-rock composition of a specific sample. P-T conditions were estimated by convectional geothermobarometry supported by phase equilibria modelling and measured garnet chemical compositions. Simulation were compared with measured garnet profiles. Simple step function and FRIDGE preliminary results of Fe-Mg - Ca - Mn garnet fractionation-diffusion modelling indicate very short timescale (between 3 and 6 Ma) for peak metamorphic conditions in the northeast Himalayan collisional system. This duration does not allow thermal re-equilibration. It is an

    The Tista River, a major tributary of the Brahmaputra drainage system (Eastern Himalaya -Sikkim) has recently incised its megafan at the topographic front of the mountain range by 30 meters. Neither the timing of deposition/incision of the megafan sediments, nor the erosion rates of the source areas have yet been investigated in detail. To constrain erosion rates in the hinterland at different temporal scales, we report cosmogenic nuclide (10Be) and thermochronological (apatite fission-track) data on modern river sands and map the results to evidence spatial variations of erosion/exhumation rates in Sikkim. Millennial erosion rates are significantly higher than geological exhumation rates, display stronger spatial variability and a contrasting pattern, suggesting that the processes controlling these rates are decoupled. Strong exhumation rates at geological timescales in southwest Sikkim (1.2 mm.yr-1) may be structurally controlled by uplift of the Lesser Himalayan duplex, while strong erosion rates at millennial scales in north Sikkim (5-6 mm.yr-1) suggest a climatic control. Cosmogenic nuclides were also used to date the onset of incision of the megafan. In addition, isotope geochemistry (ɛNd, 87Sr/86Sr) on modern river sands and late-Quaternary megafan sediments allows characterizing the isotopic signature of the different source areas and constraining variations in provenance of the Tista megafan deposits through time. Results show that the Tista fan deposits are mainly sourced from the High Himalayan Crystalline domain with excursions more influenced by the Lesser Himalaya domain. These results are consistent with the higher erosion rates identified in north Sikkim at millennial timescale. These data provide a new comprehensive view on modern erosion and long-term exhumation of the Sikkim Himalaya. This study will help our knowledge and understanding of erosional processes and sediment fluxes in mountainous environments as a function of climate and tectonics.

    Sikkim, a state in Northeast India with a population of more than 500,000 and inhabited by indigenous population of Lepchas, Bhutias and Nepalis, lies in the foothills of the Himalayas sharing borders with Tibet, Nepal and Bhutan. Northeast India is a major source of injection drug users (IDUs) and associated HIV/AIDS. Alcohol use is traditionally prevalent in Sikkim and recently, IDU behaviour has also been reported, although systematic information on epidemiology and treatment availability of substance abuse in Sikkim is not available. To study the sociodemographic and drug use profile of substance abusers using the emergency services in a tertiary care hospital. A retrospective chart review was used. Patients with history of current drug use seeking emergency services for any medical or surgical consequence incident to substance abuse from July 2000 to June 2005 (60 months) were included in the study. Data were generated from emergency case register, hospital records and case sheets. SPSS 10.0 was used for data analysis. Out of 54 patients seeking emergency services with substance abuse (1.16% of all psychiatric consultations), alcohol abusers were 77.8% and other opioid abusers 14.8%. Prevalence of IDU was 16.66%. Common opioids abused were dextrpropoxyphene and pentazocine, both analgesics. A significant number of patients (46.3%) had a history of >20 days/month frequency of abuse. Median of duration of abuse with all drugs was 12 years, while that with IDU population was 3 years. Alcohol withdrawal was the commonest cause (57.4%) of reporting to the emergency. Psychiatric comorbidity was found among 7.4%. Commonest medications used were chlordiazepoxide and clonidine, for withdrawal and naltrexone, for substitution. No standardized treatment protocol for substitution treatment was available. This is an initial attempt to study the sociodemographic and drug use profile of substance abusers in Sikkim.

    This study examines the relationships between consanguineous marriages and marriage payment, using data from two Muslim qaums living in urban and rural areas in Aligarh District, Uttar Pradesh, North India. Qaum and locality were found to have no significant association with the dowry system. Marriage payment is less common in consanguineous than in non-consanguineous marriages. However, the association between marriage payment and the type of marriage is significant at p < 0.001. The dowry system is more prevalent among the higher socioeconomic groups, while the bride-wealth system is more common among the lower socioeconomic groups.

    Community inquiry on maternal mortality was conducted in a rural area of North India. Maternal deaths were identified by multiple informants and investigated by doctors. Amongst 257 deaths registered in women in the 15-44 year age group, 55(21.4%) were maternal deaths. Maternal mortality ratio was 230 per 100,000 live births. Major causes were antepartum and postpartum hemorrhage (18.2%), puerperal sepsis (16.4%), severe anemia (16.4%), abortion (9.1%) and obstructed labor (7.3%). This rapid, simple and low cost method is recommended for application in areas where vital registration system is unsatisfactory.

    Background: The North Eastern Region in India is endemic for canine heartworm disease but in clinics accurate diagnosis is some times difficult. The aim of the present study was to determine the prevalence of occult infections for heartworm disease in canine in two geographical regions of North Eastern India. Methods: A total of 782 numbers of three categories of dogs namely, working dogs of military and paramilitary forces, pet dogs and stray dogs were screened for the presence of heartworm infection from August 2011 to July, 2012 in Guwahati (Assam) and Aizawl (Mizoram). Conventional, immunological and molecular techniques were followed for this epidemiological study. The criteria to determine the occult heartworm cases were based on the differences between heartworm positive cases in PCR test and antigen ELISA test. Results: The findings revealed an overall 22.69 percent occult case. The working dogs had highest prevalence (60%) followed by pet (29.16%) and stray dogs (17.75%). Conclusion: The highest percentage of occult heartworm infection was present in working dogs maintained under military or paramilitary forces. PMID:27047976

    Rubella virus outbreaks usually occur when a large numbers of susceptible individuals accumulate. The disease presents clinically with fever and maculopapular rash. The present study reports the investigation of rubella outbreak in a modern and well-planned village near Chandigarh, North India. The blood samples were collected from 39 cases with febrile rash and from 15 age and sex matched healthy controls residing in the same locality and subjected for the detection of Rubella IgM and IgG antibodies by Enzyme linked immunosorbent assay. The throat swabs, urine and blood samples from acute cases were also collected and subjected to RT-PCR using the primers targeting the E1 region. The genetic characterization of the rubella virus was carried out to identify the circulating genotypes. In the present outbreak, 13 laboratory confirmed cases were reported. Rubella IgM antibodies were detected in 12/39 (30.7%) patients. Rubella RNA could be detected in 83.3% (5/6) of urine, 22.2% (2/9) of throat swabs, and 8.3% (1/12) of blood samples. The rubella genotype responsible for the present outbreak was identified as genotype 1a. This outbreak highlights the need for the introduction of rubella vaccine in the National Immunization Programme of India to prevent outbreaks and to aim towards the eradication of this disease. This study reports the presence of genotype 1a in North India for the first time and stresses the need for further molecular work to identify the circulating strains of the virus.

    Snake bite envenomations are common in rural areas and the incidence peaks during monsoons in India. Prominent venomous species have been traditionally labeled as the 'big four' that includes Cobra, Krait, Russel's viper and Saw scaled viper. Systematic attempts for identification and classification of prevalent snakes in various states of India are missing till now and there is no concrete data on this aspect. The published literature however shows that some species of snakes are more prevalent in a particular region than the other parts of India e.g. Saw scaled vipers in Rajasthan. We reviewed the published literature from various parts of India and found that there is a North-South divide in the snake bite profile from India. Neurotoxic envenomations are significantly higher in North India compared to South India where Hematotoxic envenomations are prevalent. Russel's viper causes local necrosis, gangrene and compartment syndrome. These manifestations have never been reported in North Indian snake bite profile in the published literature. Early morning neuroparalysis caused by Krait is a common problem in North India leading to high mortality after snake bite. This review presents supporting evidence for the North-South divide and proposes a way forward in formulation and revision of guidelines for snake bite in India.

  14. Writing sex and sexuality: archives of colonial North India.

    2011-01-01

    This article focuses on disparate sites and subjects to reflect on and problematize the relationship between sexuality and the archives in colonial north India. I dwell on how ‘recalcitrant’ and hidden histories of sexuality can be gleaned by not only expanding our arenas of archives, but also by decentering and recasting colonial archives. I do so by specifically investigating some of the “indigenous” writings in Hindi, through texts concerning homosexuality, sex manuals, the writings of a woman ayurvedic practitioner, didactic literature and its relationship to Dalit (outcaste) sexuality, and current popular Dalit literature and its representations of the past. The debate for me here is not about the flaws of archival uses but rather of playing one archive against another, of appropriating many parallel, alternative, official, and popular archives simultaneously to shape a more nuanced and layered understanding of sexuality.

    The climatology, amplitude error, phase error, and mean square skill score (MSSS) of temperature predictions from five different state-of-the-art general circulation models (GCMs) have been examined for the winter (December-January-February) seasons over North India. In this region, temperature variability affects the phenological development processes of wheat crops and the grain yield. The GCM forecasts of temperature for a whole season issued in November from various organizations are compared with observed gridded temperature data obtained from the India Meteorological Department (IMD) for the period 1982-2009. The MSSS indicates that the models have skills of varying degrees. Predictions of maximum and minimum temperature obtained from the National Centers for Environmental Prediction (NCEP) climate forecast system model (NCEP_CFSv2) are compared with station level observations from the Snow and Avalanche Study Establishment (SASE). It has been found that when the model temperatures are corrected to account the bias in the model and actual orography, the predictions are able to delineate the observed trend compared to the trend without orography correction.

    Tuberculosis (TB) is a major public-health problem in India, having the highest number of incident and multidrug-resistant (MDR) TB cases. The study was carried out to appraise the prevalence of first-line anti-TB drug resistance in Mycobacterium tuberculosis (MTB) and its patterns among different types of TB patients from different settings in a province of North India. Of 3,704 clinical specimens, 345 (9.3%) were culture-positive, and drug-susceptibility testing was carried out for 301 MTB strains. A high level of primary and acquired drug resistance of MTB was observed in the region studied, with weighted mean of 10.5% and 28.08%, 12.81% and 29.72%, 17.12% and 29.94%, 11.97% and 27.84%, and 10.74% and 23.54% for rifampicin, isoniazid, streptomycin, ethambutol-resistant and MDR cases respectively. Drug resistance was significantly higher in pulmonary (p=0.014) and acquired drug-resistant TB cases (p<0.001). Any drug resistance (p=0.002) and MDR TB were significantly (p=0.009) associated with HIV-seropositive cases. An urgent plan is needed to continuously monitor the transmission trends of drug-resistant strains, especially MDR-TB strains, in the region. PMID:22283032

    The present study was conducted to know the smallholder pig production system in tribal areas of Sikkim State, India. Two hundred tribal farmers were selected randomly from the North and East District of the state. Information on socio-economic characteristics of farmers (gender, occupation, educational status, and farming experience), management practices, disease prevalence, and economics in pig production was collected. The study recorded the mean land holding as 1.2 ± 0.8 ha, and the number of pigs per farm was 5.0 ± 0.28. Pigs were mainly kept as a source of income, and 70 % of farmers reared crossbreed pigs. Ninety percent (90 %) of respondents practiced the intensive system of management whereby kitchen wastes along with cooked mixture comprising maize bhusa, mustard oil cake, pseudostem of banana, tuber, stem, and plant leaves were used to feed their animals. About 40.5 % of farmers procured their breeding stock from government farms that had good records and utilized veterinary services like timely vaccination and deworming. The diseases prevalent in the study area were swine fever, diarrhea, helminthoses, sarcoptic mange, pneumonia, etc. The litter sizes at birth (local, 4.3 ± 0.45; crossbreed, 7.2 ± 0.33), at weaning (local, 2.79 ± 0.24; crossbreed, 6.1 ± 0.21), and age at first farrowing (local, 365.39 ± 7.96 days; crossbreed, 337.24 ± 8.79 days) were recorded. Production costs of meat extracted from local and crossbred pigs were 1.08 $/kg and 0.86 $/kg, respectively.

    Primary infection with a varicella-zoster virus (VZV) leads to chickenpox. Though the incidence of the disease has decreased in many developed countries due to the introduction of the varicella vaccine, outbreaks continue to occur in developing countries. The present study reports an outbreak of varicella in an urbanised village in the vicinity of Chandigarh City in North India in November 2013. The outbreak was confirmed by the detection of VZV IgM antibodies in serum samples of clinically suspected patients. Vesicular fluid samples were collected from 8 patients with active lesions and tested for VZV DNA by polymerase chain reaction. Blood samples were also collected from 17 healthy controls residing in the same locality and tested for the presence of VZV IgM and IgG antibodies. A total of 18 cases occurred, and the majority of them (67%) were <15 years of age. Of 17 samples collected from patients with the clinically suspected disease, 13 (76.5%) showed the presence of VZV IgM antibodies. Of the healthy controls, 6 were VZV IgM positive and 4 of them developed symptomatic disease on follow-up. VZV DNA was positive in 5/8 (62.5%) of the patients. In one patient, VZV DNA was detected in the absence of an IgM antibody response. The introduction of varicella vaccine in the universal immunisation programme of India may help to prevent these outbreaks; however, the cost-benefit analysis needs to be carried out before making such policies.

    Ornamental fishes are traded with multiple names from various parts around the world, including North East India. Most are collected from the wild, due to lack of species-specific culture or breeding, and therefore, such unmanaged collection of the wild and endemic species could lead to severe threats to biodiversity. Despite many regulatory policies, trade of threatened species, including the IUCN listed species have been largely uncontrolled, due to species identification problems arising from the utilization of multiple trade names. So, the development of species-specific DNA marker is indispensable where DNA Barcoding is proved to be helpful in species identification. Here, we investigated, through DNA Barcoding and morphological assessment, the identification of 128 ornamental fish specimens exported from NE India from different exporters. The generated sequences were subjected to similarity match in BOLD-IDS as well as BLASTN, and analysed using MEGA5.2 for species identification through Neighbour-Joining (NJ) clustering, and K2P distance based approach. The analysis revealed straightforward identification of 84 specimens into 35 species, while 44 specimens were difficult to distinguish based on CO1 barcode alone. However, these cases were resolved through morphology, NJ and distanced based method and found to be belonging to 16 species. Among the 51 identified species, 14 species represented multiple trade names; 17 species belonged to threatened category. Species-level identification through DNA Barcoding along with traditional morphotaxonomy reflects its efficacy in regulating ornamental fish trade and therefore, appeals for their conservation in nature. The use of trade names rather than the zoological name created the passage for trafficking of the threatened species and demands immediate attention for sustaining wildlife conservation.

    Rural households in India rely extensively on informal biomedical providers, who lack valid medical qualifications. Their numbers far exceed those of formal providers. Our study reports on the education, knowledge, practices and relationships of informal providers (IPs) in two very different districts: Tehri Garhwal in Uttarakhand (north) and Guntur in Andhra Pradesh (south). We mapped and interviewed IPs in all nine blocks of Tehri and in nine out of 57 blocks in Guntur, and then interviewed a smaller sample in depth (90 IPs in Tehri, 100 in Guntur) about market practices, relationships with the formal sector, and their knowledge of protocol-based management of fever, diarrhoea and respiratory conditions. We evaluated IPs’ performance by observing their interactions with three patients per condition; nine patients per provider. IPs in the two districts had very different educational backgrounds—more years of schooling followed by various informal diplomas in Tehri and more apprenticeships in Guntur, yet their knowledge of management of the three conditions was similar and reasonably high (71% Tehri and 73% Guntur). IPs in Tehri were mostly clinic-based and dispensed a blend of allopathic and indigenous drugs. IPs in Guntur mostly provided door-to-door services and prescribed and dispensed mainly allopathic drugs. In Guntur, formal private doctors were important referral providers (with commissions) and source of new knowledge for IPs. At both sites, IPs prescribed inappropriate drugs, but the use of injections and antibiotics was higher in Guntur. Guntur IPs were well organized in state and block level associations that had successfully lobbied for a state government registration and training for themselves. We find that IPs are firmly established in rural India but their role has grown and evolved differently in different market settings. Interventions need to be tailored differently keeping in view these unique features. PMID:25012795

    Background & objectives: Trichinellosis is a parasitic infection caused by Trichinella nematodes, acquired from consumption of raw meat. However, data from Indian subcontinent are limited. The aim of this study was to investigate the clinical and biochemical profile of a suspected trichinellosis outbreak in a village in Tehri Garhwal district of Uttarakhand state in north India. Methods: Three index cases presenting as acute febrile myalgia syndrome with eosinophilia, after consumption of uncooked pork in a common feast, were confirmed as trichinellosis on muscle biopsy. A detailed epidemiological survey was carried out in the affected community and all the people who participated in the feast were investigated for clinical and biochemical profile. Results: A total of 54 patients were evaluated in the study. The type of pork consumed included uncooked in 24 per cent (n=13), open fire roasted in 39 per cent (n=21) and fried in 37 per cent (n=20). Clinical symptoms were found in those who consumed pork in uncooked or open fire roasted form (n=34). These included fever with chills and myalgia (100%), periorbital oedema (67%), dyspnoea (9%), and dysphagia (3%). Laboratory parameters studied in both symptomatic and asymptomatic patients showed eosinophilia in 90 per cent (n=41), raised ESR in 98 per cent (n=45), and an elevated creatinine phosphokinase (CPK) level in 85 per cent (n=39). All symptomatic patients were treated with a short course of oral steroids and albendazole therapy. Conclusions: Trichinella infection is not uncommon in India, and should be suspected in case of acute febrile myalgia especially in areas, where habits of consumption of raw meat is more prevalent.

    Background Cancer is a leading cause of death worldwide. A large proportion of cancer deaths are preventable through early detection but there are a range of social, emotional, cultural and financial dimensions that hinder the effectiveness of cancer prevention and treatment efforts. Cancer stigma is one such barrier and is increasingly recognized as an important factor influencing health awareness and promotion, and hence, disease prevention and control. The impact and extent of stigma on the cancer early detection and care continuum is poorly understood in India. Objectives To evaluate cancer awareness and stigma from multiple stakeholder perspectives in North India, including men and women from the general population, health care professions and educators, and cancer survivors. Materials and Methods A qualitative study was conducted with in-depth interviews (IDIs) and focus group discussions (FGDs) among 39 individuals over a period of 3 months in 2014. Three groups of participants were chosen purposively - 1) men and women who attended cancer-screening camps held by the Indian Cancer Society, Delhi; 2) health care providers and 3) cancer survivors. Results Most participants were unaware of what cancers are in general, their causes and ways of prevention. Attitudes of families towards cancer patients were observed to be positive and caring. Nevertheless, stigma and its impact emerged as a cross cutting theme across all groups. Cost of treatment followed by lack of awareness, beliefs in alternate medicines were identified as some of the major barriers to seeking care. Conclusions This study suggests a need for spreading awareness, knowledge about cancers and assessing associated impact among the people. Also future research is recommended to help eradicate stigma from the society and reduce cancer-related stigma in the Indian context. PMID:26320509

    Cancer is a leading cause of death worldwide. A large proportion of cancer deaths are preventable through early detection but there are a range of social, emotional, cultural and financial dimensions that hinder the effectiveness of cancer prevention and treatment efforts. Cancer stigma is one such barrier and is increasingly recognized as an important factor influencing health awareness and promotion, and hence, disease prevention and control. The impact and extent of stigma on the cancer early detection and care continuum is poorly understood in India. To evaluate cancer awareness and stigma from multiple stakeholder perspectives in North India, including men and women from the general population, health care professionals and educators, and cancer survivors. A qualitative study was conducted with in-depth interviews (IDIs) and focus group discussions (FGDs) among 39 individuals over a period of 3 months in 2014. Three groups of participants were chosen purposively - 1) men and women who attended cancer screening camps held by the Indian Cancer Society, Delhi; 2) health care providers and 3) cancer survivors. Most participants were unaware of what cancers are in general, their causes and ways of prevention. Attitudes of families towards cancer patients were observed to be positive and caring. Nevertheless, stigma and its impact emerged as a cross cutting theme across all groups. Cost of treatment, lack of awarenes and beliefs in alternate medicines were identified as some of the major barriers to seeking care. This study suggests a need for spreading awareness, knowledge about cancers and assessing associated impact among the people. Also Future research is recommended to help eradicate stigma from the society and reduce cancer-related stigma in the Indian context.

    The objective of this study is to examine the factors that influence the occurrence of childhood anaemia in North-East India by exploring dataset of the Reproductive and Child Health-II Survey (RCH-II). The study population consisted of 10,137 children in the age-group of 0-6 year(s) from North-East India to explore the predictors of childhood anaemia by means of different background characteristics, such as place of residence, religion, household standard of living, literacy of mother, total children ever born to a mother, age of mother at marriage. Prevalence of anaemia among children was taken as a polytomous variable. The predicted probabilities of anaemia were established via multinomial logistic regression model. These probabilities provided the degree of assessment of the contribution of predictors in the prevalence of childhood anaemia. The mean haemoglobin concentration in children aged 0-6 year(s) was found to be 11.85 g/dL, with a standard deviation of 5.61 g/dL. The multiple logistic regression analysis showed that rural children were at greater risk of severe (OR = 2.035; p = 0.003) and moderate (OR = 1.23; p = 0.003) anaemia. All types of anaemia (severe, moderate, and mild) were more prevalent among Hindu children (OR = 2.971; p = 0.000), (OR = 1.195; p = 0.010), and (OR = 1.201; p = 0.011) than among children of other religions whereas moderate (OR = 1.406; p = 0.001) and mild (OR = 1.857; p=0.000) anaemia were more prevalent among Muslim children. The fecundity of the mother was found to have significant effect on anaemia. Women with multiple children were prone to greater risk of anaemia. The multiple logistic regression analysis also confirmed that children of literate mothers were comparatively at lesser risk of severe anaemia. Mother's age at marriage had a significant effect on anaemia of their children as well.

    Introduction: Ulcerative colitis occurs worldwide. It is considered common in most of Europe and North America and uncommon in most of the developing Asian countries. The incidence/prevalence of ulcerative colitis varies not only according to geographical region but also with race and ethnicity. There are no reported data from India on the incidence of the disease and its prevalence. Material and methods: A house to house survey was conducted by questionnaire, formulated to enquire about symptoms that are suggestive of ulcerative colitis. Those with prolonged diarrhoea with or without rectal bleeding were considered as suspected cases. These suspected cases were subjected to video sigmoidoscopy/colonoscopy and rectal biopsy. In addition, patients already diagnosed and receiving treatment for ulcerative colitis, encountered during the survey, were reviewed. Resurvey of the same areas was conducted after a one year interval to detect new cases. Using direct methods, standardised rates were calculated using world standard population weights 22, 18, 16, 12, 12, 9, 7, 3, and 1 for each 10 year age group. Standardised rates were also obtained separately for males, females, and combined populations, using the Punjab state 1991 population census data. Rates were also estimated according to UK 2000 population data. Ninety five per cent confidence intervals (95% CI) of prevalence and incidence rates of ulcerative colitis were estimated under the assumption that the distribution of cases followed a Poisson probability model. Results: A total population of 51 910 were screened from January to March 1999. We identified 147 suspected cases and of these 23 were finally established as ulcerative colitis cases, giving a crude prevalence rate of 44.3 per 100 000 inhabitants (95% CI 29.4–66.6). A second visit to the same areas after one year identified 10 suspected cases in a population of 49 834. Of these, three were confirmed as “definite” ulcerative colitis giving a crude

    This study investigates spatial patterns in glacier characteristics and area changes at decadal scales in the eastern Himalaya - Nepal (Arun and Tamor basins), India (Teesta basin in Sikkim) and parts of China and Bhutan - based on various satellite imagery: Corona KH4 imagery, Landsat 7 Enhanced Thematic Mapper Plus (ETM+) and Advanced Spaceborne Thermal Emission Radiometer (ASTER), QuickBird (QB) and WorldView-2 (WV2). We compare and contrast glacier surface area changes over the period of 1962-2000/2006 and their dependency on glacier topography (elevation, slope, aspect, percent debris cover) and climate (solar radiation, precipitation) on the eastern side of the topographic barrier (Sikkim) versus the western side (Nepal). Glacier mapping from 2000 Landsat ASTER yielded 1463 ± 88 km2 total glacierized area, of which 569 ± 34 km2 was located in Sikkim and 488 ± 29 km2 in eastern Nepal. Supraglacial debris covered 11% of the total glacierized area, and supraglacial lakes covered about 5.8% of the debris-covered glacier area alone. Glacier area loss (1962 to 2000) was 0.50 ± 0.2% yr-1, with little difference between Nepal (0.53 ± 0.2% yr-1) and Sikkim (0.44 ± 0.2% yr-1. Glacier area change was controlled mostly by glacier area, elevation, altitudinal range and, to a smaller extent, slope and aspect. In the Kanchenjunga-Sikkim area, we estimated a glacier area loss of 0.23 ± 0.08% yr-1 from 1962 to 2006 based on high-resolution imagery. On a glacier-by-glacier basis, clean glaciers exhibit more area loss on average from 1962 to 2006 (34%) compared to debris-covered glaciers (22%). Glaciers in this region of the Himalaya are shrinking at similar rates to those reported for the last decades in other parts of the Himalaya, but individual glacier rates of change vary across the study area with respect to local topography, percent debris cover or glacier elevations.

    Iodine deficiency disorders (IDDs) are the most common cause of preventable brain damage globally. The strategy of prevention and control of iodine deficiency is based on iodine supplementation. Edible salt iodization and iodized oil injections are the two most commonly used vehicles for iodine supplementation. The objective of the study was to conduct a cost-benefit analysis of the two programs of iodine supplementation, i.e., iodized salt program (ISP) and iodized oil program (IOP) against no preventive program (NPP) option. The study was conducted in 1990 in the state of Sikkim in India. The costs were calculated on the assumption of universal coverage of ISP and coverage of IOP among all children aged 0-14 years and women in the age group of 15-44 years. Direct and indirect cost of ISP and direct cost of IOP was computed based on the costs of year 1991. The discount rate taken was 10% and all the costs were converted to the year 2010 using wholesale price index (WPI) data. Consequences in terms of health effects, Social/emotional effects, and resource use were included. The discounted cost of ISP and IOP was Rs. 59,225,964 and Rs. 46,145,491, respectively. In ISP, 64.1% of the total cost was required for salt iodization, 17.6% for monitoring, and 18.3% for communication. In IOP, 50.9% of the costs were required for iodized oil; rest was for syringes and needles, manpower expenses, travel, and communication. Total resource saving was Rs. 95,566,220 for ISP and Rs. 92,177,548 for IOP. Incremental benefit for ISP was Rs. 36,340,256 and Rs. 46,032,057 for IOP. The cost-benefit ratio for ISP was 1.61 and 2.00 for IOP. IOP has a higher cost-benefit ratio for prevention of IDDs than ISP in the state of Sikkim, India.

    In this discussion of India attention is directed to the following: the people; geography; history; government; political conditions; the economy; foreign relations (Pakistan and Bangladesh, China, and the Soviet Union); defense; and the relations between the US and India. In 1983 India's population was estimated at 746 million with an annual growth rate of 2.24%. The infant mortality rate was estimated at 116/1000 in 1984 with a life expectancy of 54.9 years. Although India occupies only 2.4% of the world's land area, it supports nearly 15% of the world's population. 2 major ethnic strains predominate in India: the Aryan in the north and the Dravidian in the south, although the lines between them are blurred. India dominates the South Asian subcontinent geographically. The people of India have had a continuous civilization since about 2500 B.C., when the inhabitants of the Indus River Valley developed an urban culture based on commerce, trade, and, to a lesser degree, agriculture. This civilization declined about 1500 B.C. and Aryan tribes originating in central Asia absorbed parts of its culture as they spread out over the South Asian subcontinent. During the next few centuries, India flourished under several successive empires. The 1st British outpost in South Asia was established in 1619 at Surat on the northwestern coast of India. The British gradually expanded their influence until, by the 1850s, they controlled almost the entire area of present-day India. Independence was attained on August 15, 1947, and India became a dominion within the Commonwealth of Nations with Jawaharlal Nehru as prime minister. According to its constitution, India is a "sovereign socialist secular democratic republic." Like the US, India has a federal form of government, but the central government in India has greater power in relation to its states, and government is patterned after the British parliamentary system. The Congress Party has ruled India since independence with the

    Background: Worldwide, the stigma and discrimination impede HIV-AIDS programs across the continuum of prevention to care. We studied stigma and related issues in HIV-positive subjects. Materials and Methods: At a tertiary care hospital in North India, we studied 100 HIV-positive outpatients not receiving antiretroviral therapy. The subjects self-administered ‘Tanzania Stigma Indicator and Community Endline-Individual Questionnaire’. Psychiatric morbidity was screened with General Health Questionnaire (GHQ-I2 Hindi) and diagnosed with Structured Clinical Interview for DSM-IV (SCID). Results: A typical subject was middle aged (25-44 years, 77%), school non-completer (63%), village dweller (61%), and male (59%). Only 35 subjects could differentiate between HIV and AIDS, and only 24 were aware of antiretroviral therapy. Unprotected sex, sharing injections, and blood transfusions were reported spontaneously as possible sources of transmission by 56-79% subjects each. About 80% of subjects reported no fear in touching HIV-positive subjects or their objects. Avoiding injections, being faithful to uninfected partner, avoiding blood transfusions, using condoms, and avoiding sharing razors/blades were reported spontaneously as HIV preventive measures by 40 to 26 subjects each. Half of the subjects blamed self for contracting HIV. Only 38 subjects reported others behaving differently with HIV-positive subjects. HIV status disclosure was reported by 98 subjects (73 to family or relatives). Urban subjects reported higher primary stigma and shame or blame. Psychiatric disorders, present in 45 subjects, showed no association with stigma items. Conclusions: The subjects had a limited knowledge, especially of treatment aspects. Stigma showed no association with psychiatric disorders. The study reflects a strong need for public health measures to enhance awareness and knowledge about HIV/AIDS. PMID:23723539

    The Tista River is a major tributary of the Brahmaputra drainage system (Eastern Himalaya). Its headwaters are located in the glaciated northernmost parts of the Sikkim and its catchment area amounts to more than 12,000 km2 including a depositional megafan (extending mostly in Bangladesh and West Bengal-India). The Tista has recently incised its megafan at the topographic front of the mountain range by about 30 meters. Neither the timing of deposition/incision of the megafan sediments, nor the erosion rates of the source areas as well as their potential relationships, have been investigated in detail. Comparing these data is essential to distinguish between a climatic and/or tectonic control of the evolution of the Sikkim Himalaya and piedmont. To constrain erosion rates in the hinterland at different temporal scales (respectively millenial and geological timescales), we report cosmogenic nuclide (10Be) and thermochronological (apatite fission-tracks) data on modern river sands. Results were mapped to evidence spatial variations of erosion/exhumation rates in the Tista catchment. Cosmogenic nuclides were also used to date the onset of incision of the megafan and relate it to potential changes in hinterland erosion. In addition, isotope geochemistry (ɛNd and 87Sr/86Sr) performed on modern river sands and Late-Quaternary megafan sediments allows characterizing the isotopic signature of the different source areas and constraining variations in provenance of the Tista megafan deposits through time in response to changing climatic conditions. Results show that the Tista fan deposits are mainly sourced from the High Himalayan Crystalline domain with excursions more influenced by the Lesser Himalaya domain. These data provide a new comprehensive view on modern erosion and long-term exhumation of the Sikkim Himalaya. This study of a "closed system" will help our knowledge and understanding of erosional processes and sediment fluxes in mountainous environments as a

    Gallstones (GS) in south India (SI) are predominantly pure pigment or mixed, while in North India (NI), these are either pure cholesterol or mixed. While cholesterol rich gallbladder (GB) bile predicts cholesterol GS, constituent of bile in primary pigment GS is not known. We compared the composition of GB bile from healthy liver donors and patients with GS from north and south India. Gallbladder bile from healthy liver donors from north (10) and south India (8) served as controls. Cases were patients from north (21) and south India (17) who underwent cholecystectomy for GS disease. Gallbladder bile from both cases and controls was analyzed for cholesterol, lecithin (phospholipid), and bile salts. Gallstones were classified as cholesterol, mixed, and pigment based on morphology and biochemical analysis. The median cholesterol concentration in control bile from north was significantly high compared to south (p<0.001) with no difference in lecithin and bile salts (p NS). Except for one sample each from north and south, the cholesterol solubility of controls was within the critical micellar zone. Mixed GS were most frequent in north India (61.9 %) while pigment GS dominated in south (61.9 %). The median cholesterol concentration in bile samples of cholecystectomy patients from north India was significantly high GS (p < 0.00001) with significant lowering of bile salts and lecithin (p < 0.00001). In south India, patients with mixed GS had high cholesterol content in bile compared to controls and patients with pigment GS; bile in latter had significantly higher concentration of bile salt compared to controls and mixed GS. The ternary plot confirmed the composition of GB bile from north and south India. Gallbladder bile in controls and patients with GS from north India had significantly high cholesterol concentration. In south India, patients with mixed GS had cholesterol rich bile while pigment GS had higher concentrations of bile salts.

    One of the criteria for recommending cholecystectomy for silent gall stones, is gall stones in regions with high incidence of gall bladder cancer. Both gall stones and gall bladder cancer are common in North India. All tertiary care centres in India report high rates of gall bladder cancer (GBC) incidence and poor treatment outcomes in the majority of cases due to advanced stage of presentation. Csendes of Chile has reported very high incidence of gallbladder cancer in Chile and Bolivia and advocated prophylactic cholecystectomy in asymptomatic patients. Incidence rate of gall bladder cancer in Indian males is equal to that of Chile, whereas in females, the rates are almost double the rates of Chile. Indians have also been found to have high concentrations of heavy metals in gall bladder wall, and antibodies to tumor suppressor genes. In India, gall bladder cancer is the commonest GI cancer in women and fourth commonest cancer overall in the female population. In view of the epidemiology and clinical scenario of gall bladder cancer and proven safety of laparoscopic cholecystectomy, there is a need to act before it is too late in the current rates of gall bladder cancer. This study looks at the evidence correlating gall stones and gall bladder cancer, in relation to India. There is pressing evidence today to justify a strategy of prophylactic cholecystectomy in silent gall stones in North India. Data for this study was selected through an internet based search for literature concerning gall stones and gall bladder cancer in India, and for prophylactic cholecystectomy.

    The recent earthquake of Mw 6.9 occurred on September 18, 2011 in Sikkim-Nepal border region. The hypocenter parameters determined by the Indian Meteorological Department shows that the epicentre is at 27.7°N, 88.2°E and focal depth of 58Km, located closed to the north-western terminus of Tista lineament. The reported aftershocks are linearly distributed in between Tista and Golapara lineament. The microscopic and geomorphologic studies infer a dextral strike-slip faulting, possibly along a NW-SE oriented fault. Landslides caused by this earthquake are distributed along Tista lineament . On the basis of the aftershock distribution, Kumar et al. (2012), have suggested possible NW orientation of the causative fault plane. The epicentral region of Sikkim bordered by Nepal, Bhutan and Tibet, comprises a segment of relatively lower level seismicity in the 2500km stretch of the active Himalayan Belt. The north Sikkim earthquake was felt in most parts of Sikkim and eastern Nepal; it killed more than 100 people and caused damage to buildings, roads and communication infrastructure. Through this study we focus on the earthquake source parameters and the kinematic rupture process of this particular event. We used tele-seismic body waveformsto determine the rupture pattern of earthquake. The seismic-rupture pattern are generally complex, and the result could be interpreted in terms of a distribution of asperities and barriers on the particular fault plane (Kikuchi and Kanamori, 1991).The methodology we adopted is based on the teleseismic body wave inversion methodology by Kikuchi and Kanamori (1982, 1986 and 1991). We used tele-seismic P-wave records observed at teleseismic distances between 50° and 90° with a good signal to noise ratio. Teleseismic distances in the range between 50° and 90° were used, in order to avoid upper mantle and core triplications and to limit the path length within the crust. Synthetic waveforms were generated gives a better fit with triangular

    Marcha or murcha is a traditional amylolytic starter used to produce sweet-sour alcoholic drinks, commonly called jaanr in the Himalayan regions of India, Nepal, Bhutan, and Tibet (China). The aim of this study was to examine the microflora of marcha collected from Sikkim in India, focusing on yeast flora and their roles. Twenty yeast strains were isolated from six samples of marcha and identified by genetic and phenotypic methods. They were first classified into four groups (Group I, II, III, and IV) based on physiological features using an API test. Phylogenetic, morphological, and physiological characterization identified the isolates as Saccharomyces bayanus (Group I); Candida glabrata (Group II); Pichia anomala (Group III); and Saccharomycopsis fibuligera, Saccharomycopsis capsularis, and Pichia burtonii (Group IV). Among them, the Group I, II, and III strains produced ethanol. The isolates of Group IV had high amylolytic activity. Because all marcha samples tested contained both starch degraders and ethanol producers, it was hypothesized that all four groups of yeast (Group I, II, III, and IV) contribute to starch-based alcohol fermentation.

    Taenia solium is the major cause of taeniasis and cysticercosis/neurocysticercosis (NCC) in the developing countries including India, but the existence of other Taenia species and genetic variation have not been studied in India. So, we studied the existence of different Taenia species, and sequence variation in Taenia isolates from human (proglottids and cysticerci) and swine (cysticerci) in North India. Amplification of cytochrome c oxidase subunit 1 gene (cox1) was done by polymerase chain reaction (PCR) followed by sequencing and phylogenetic analysis. We identified two species of Taenia i.e. T. solium and Taenia asiatica in our isolates. T. solium isolates showed similarity with Asian genotype and nucleotide variations from 0.25 to 1.01 %, whereas T. asiatica displayed nucleotide variations ranged from 0.25 to 0.5 %. These findings displayed the minimal genetic variations in North Indian isolates of T. solium and T. asiatica.

    This study demonstrates the variability in Western Disturbance during the sudden stratospheric warming (SSW) period and its eventual influence on the north Indian weather pattern. The modulations in the north Indian winter under the two phases of the Quasi-biennial oscillation (QBO) during SSW periods are also examined. The analysis has been carried out by using the ERA interim reanalysis dataset for different pressure levels in the stratosphere and upper troposphere during the time period of 1980-2010. The daily minimum surface temperature data published by India Meteorological Department from 1969 to 2013 has been used for the analysis of temperature anomaly over north India during SSW. The period of intense stratospheric warming witnesses a downward propagation and intensification of kinetic energy from stratosphere to upper troposphere over the Mediterranean and Caspian Sea. When QBO is in easterly phase, the cooling over north India is much larger when compared to the westerly phase during instances of SSW. SSW coincident with the easterly phase of QBO causes an intensified subtropical jet over the mid-latitude regions. The modulation in circulation pattern in stratosphere and upper troposphere when ENSO occurs during SSW period is also analysed separately. This study provides the link among SSW, Western Disturbances and the north Indian cooling during winter season.

These events have been relocated using body wave phase data from local and regional seismograms. The decay of coda amplitudes at a range of central frequencies (1 to 12 Hz) has been measured for 74 earthquake-receiver pairs. These measurements are combined to estimate the frequency-dependent coda Q of the form Q( f) = Q0 f η. The estimated Q0 values range from 80 to 200, with an average of 123 ± 29; and η ranges from 0.92 to 1.04, with an average of 0.98 ± 0.04. To study the lateral variation of Q0 and η, we regionalized the measured Q values by combining all the earthquake-receiver path measurements through a back projection algorithm. We consider a single back-scatter model for the coda waves with elliptical sampling and parametrize the sampled area using 0.2° square grids. A nine-point spatial smoothening (similar to spatial Gaussian filter) is applied to stabilize the inversion. This is done at every frequency to observe the spatial variation of Q( f) and subsequently combined to obtain η variations. Results of our study reveal that the Sikkim Himalaya is characterized by low Q0 (80-100) compared to the foreland basin to its south (150-200) and the Nepal Himalaya to its west (140-160). The low Q and high η in Sikkim Himalaya is attributed to extrinsic scattering attenuation from structural heterogeneity and active faults within the crust, and intrinsic attenuation due to anelasticity in the hotter lithosphere beneath the actively deforming mountain belt. Similar low Q and high η values had also been observed in northwest and Garhwal-Kumaun Himalaya.

  9. Genetic population structure of the malaria vector Anopheles baimaii in north-east India using mitochondrial DNA

    Background Anopheles baimaii is a primary vector of human malaria in the forest settings of Southeast Asia including the north-eastern region of India. Here, the genetic population structure and the basic population genetic parameters of An. baimaii in north-east India were estimated using DNA sequences of the mitochondrial cytochrome oxidase sub unit II (COII) gene. Methods Anopheles baimaii were collected from 26 geo-referenced locations across the seven north-east Indian states and the COII gene was sequenced from 176 individuals across these sites. Fifty-seven COII sequences of An. baimaii from six locations in Bangladesh, Myanmar and Thailand from a previous study were added to this dataset. Altogether, 233 sequences were grouped into eight population groups, to facilitate analyses of genetic diversity, population structure and population history. Results A star-shaped median joining haplotype network, unimodal mismatch distribution and significantly negative neutrality tests indicated population expansion in An. baimaii with the start of expansion estimated to be ~0.243 million years before present (MYBP) in north-east India. The populations of An. baimaii from north-east India had the highest haplotype and nucleotide diversity with all other populations having a subset of this diversity, likely as the result of range expansion from north-east India. The north-east Indian populations were genetically distinct from those in Bangladesh, Myanmar and Thailand, indicating that mountains, such as the Arakan mountain range between north-east India and Myanmar, are a significant barrier to gene flow. Within north-east India, there was no genetic differentiation among populations with the exception of the Central 2 population in the Barail hills area that was significantly differentiated from other populations. Conclusions The high genetic distinctiveness of the Central 2 population in the Barail hills area of the north-east India should be confirmed and its

    The north-eastern region of India is endowed with a great wealth of plant genetic resources. Out of the vast floral diversity of the region, a large number of indigenous plant species and their wild forms constitute the routine vegetables of the inhabitants, which provide sufficient nutrients and medicinal values for the people. They seem to be quite healthy on average, even though the ethnic tribes are ignorant about the concept of balanced diet and healthcare. This paper describes the mineral (calcium, magnesium, iron, potassium and phosphorus) contents and chemical composition in percentages such as carbohydrate, protein, fat, and so forth, found in 15 traditional vegetable species collected from different parts of North-east India. The results of this study contribute to the knowledge on vitamin contents in these vegetables. The amounts of ascorbic acid found in some species were much higher than the amount present in many conventional vegetables.

    Leptospirosis has been recognised as an emerging global public health problem. The aim of our study was to explore the epidemiological and clinical pattern of disease occurrence in suspected cases and to search for any existing co-infections. Ours was a retrospective study in patients with acute febrile illness in north India over a period of three years (April 2011 to June 2014). Serological diagnosis of leptospirosis was made using the PanBio IgM ELISA kit. Using modified Faine's criteria, presumptive and possible diagnosis was made in 57% and 34% cases, respectively. Most of the affected population was resident in north and central India. Nineteen patients showed co-infection with other common pathogens prevailing locally. There is a need to increase awareness and understand the local sero-epidemiological pattern of leptospirosis so that timely preventive and curative action may be taken by healthcare authorities.

    Fifteen species of freshwater Nematomorpha have been described from India, five of which belong to the genus Chordodes. This paper describes one new species of horsehair worms (Nematomorpha): Chordodes lasuboni and a new record, C. moutoni from North-East India, which raises the total number of described species from India to 17. Chordodes lasuboni is characterized by a novel cuticular pattern in the head region and by the presence of slender, hooked thorn areoles on the body cuticle. Compared to the large size and ecological diversity of India, the nematomorph fauna is regarded as under-sampled and several new species are to be expected.

    Taenia solium taeniasis/cysticercosis is a major public health problem in developing countries. This study reports genotypic analysis of T. solium cysticerci collected from two different endemic areas of North (Chandigarh) and North East India (Dibrugarh) by the sequencing of mitochondrial cytochrome c oxidase subunit 1 (cox1) gene. The variation in cox1 sequences of samples collected from these two different geographical regions located at a distance of 2585 km was minimal. Alignment of the nucleotide sequences with different species of Taenia showed the similarity with Asian genotype of T. solium. Among 50 isolates, 6 variant nucleotide positions (0.37% of total length) were detected. These results suggest that population in these geographical areas are homogenous.

    Introduction: In North India snake bite deaths are predominantly seen with neurotoxic envenomations (NEs) whereas in South India the hemotoxic envenomation (HE) is more common. Krait is responsible for most deaths in North India. It bites people sleeping on the floors, mostly at night. We describe the profile of venomous snake bites over 1 year in 2013. Materials and Methods: The study was conducted in a rural tertiary care hospital in North India. Demographics, circumstances of bite, envenomation, first aid, delay, consultation, treatment, anti-venom, and outcomes were recorded for all victims of snake bite. We included all consecutive adult (>18 years) venomous snake bite victims admitted from January to December 2013. Results: A total of 91 patients with venomous snake bites were included in the study. Pure NEs were 41 (45.1%), pure HE in 31 (34.1%), 7 (7.7%) had mixed NE + HE, and 12 (13.2%) had only local swelling. Forty patients (44%) were bitten during sleep presenting as NE (92.5%), NE + HE (5%), and HE (2.5%). Findings in the 51 patients (56%) bitten during activity were HE (58.8%), local swelling (23.5%), NE + HE (9.8%), and NE (7.8%) (P < 0.0001). First aid was sought by 24 NE patients out of which 23 (96%) went to alternate practitioners or religious healers. Conclusion: Almost all (97.5%) bites during sleep resulted in NE in our study. About 96% of NE sought first aid from alternate practitioners or religious healers in hope of some magical treatment. Thus, a deadly combination of krait bite during sleep and wrong health seeking behavior is responsible for high mortality krait bites in this region. Mass public awareness regarding krait bites can prevent mortality in many such cases. PMID:27722112

    Successive outbreaks of acute watery diarrhoea occurred in Talikoti and Harnal, located in Bijapur District of the southern Indian s0 tate of Karnataka, in July and August 2012, respectively. These outbreaks were investigated to identify the aetiology and epidemiology. Information was collected from the local population and health centres. Stool and water samples were collected from the admitted patients and their drinking water sources. Standard microbiological and PCR techniques were employed for isolation and characterization of the pathogen. While 101 people (0.38%) were affected in Talikoti, 200 (20.94%) were affected in Harnal which is a small remote village. All age groups were affected but no death occurred. While the outbreak was smaller, longer and apparently spread by person to person contact in Talikoti, it occurred as a single source flash outbreak at Harnal. A single clone of toxigenic Vibrio cholerae O1 Ogawa biotype El Tor was isolated from the two stool samples obtained from Talikoti and subsequently from three of five stool samples obtained from Harnal indicating village to village spread of the aetiological agent. Striking similarity in antibiotic resistance profiles of these isolates with a particular strain isolated from the city of Belgaum, 250 km away, in 2010, prompted tracking the lineage of the V. cholerae isolates by DNA fingerprinting. Random amplified polymorphic DNA (RAPD) fingerprinting assay helped confirm the origin of the incriminating strain to Belgaum. Our study reported the first twin outbreak of cholera in two remote areas of Bijapur district, Karnataka, south India. It also indicated the need for immediate preparedness to deal with such emergencies.

    There are minimal data on the use of electroconvulsive therapy (ECT) in adolescents from India. The present study aimed to evaluate the clinical profile and effectiveness of ECT in adolescents (aged 13-18 years). A retrospective chart review was carried out to identify adolescents (aged 13-18 years) who had received ECT during the period 1999-2011. During the study period, 39 such patients received ECT; complete records of 25 patients were available. Details regarding their sociodemographic, clinical, and treatment data were extracted from these records for the present study. During the study period, 658 patients received ECT, of which 39 were aged 18 or younger (5.9%). Schizophrenia (n = 14; 56%) was the commonest diagnosis for which ECT was used in adolescents, followed by depression (n = 3; 12%). Catatonic symptoms (n = 17; 68%) were the most common symptoms among these subjects. Electroconvulsive therapy was considered as a treatment of choice taking the clinical picture account in about three fourths of the patients (n = 19; 76%). The mean (SD) numbers of ECTs administered per patient were 10.1 (4.87) (range, 2-21). The mean (SD) response rate to ECT was 76% (23.3%) (range, 31%-100%). Response rates according to diagnosis were the following: 76.3% for schizophrenia, 87.2% for depression, 81.8% for psychosis (not otherwise specified), and 77.7% for acute and transient psychosis. Response rate in patients with catatonia was 91.6%. Prolonged seizures, nausea and vomiting, and headache were reported in 2 cases each. Electroconvulsive therapy is used less frequently in children and adolescents compared to the older patients. This study shows that ECT is effective in the treatment of severe psychiatric disorders in adolescents and is associated with the same frequency of adverse effects as the adults.

    The paleoposition of South China during the Ediacaran-Silurian is important for understanding the assembly of Gondwana. We report here the tectonostratigraphic evolution of the Ediacaran-Silurian Nanhua foreland basin in South China, and discuss South China's connection with Gondwana and potential tectonic triggers for both the Wuyi-Yunkai orogeny in South China and the Bhimphedian orogeny in north India. The Nanhua basin was involved in a three-stage evolution, which are: Stage 1 (the Ediacaran-Cambrian) recording the start of tectonic subsidence with turbiditic marine clastic deposition, fed by exotic orogens outboard South China; Stage 2 (the Ordovician to earliest-Silurian) featured by migrating depocentres with dominant shallow marine to deltaic clastic deposition, fed by the local Wuyi-Yunkai orogen; and Stage 3 (the Silurian) showing the arrival of depocentre in the Yangtze Block during the waning stage of the Wuyi-Yunkai orogeny with deltaic deposition in the remanent foreland basin. Detrital zircon analyses of the Ediacaran-Silurian sandstones across the Nanhua basin reveal a prominent age population of 1100-900 Ma (with a peak age at ~980 Ma) and moderate populations of Archean-Paleozoic ages, grossly matching that of crystalline and sedimentary rocks in northern India. Zircon isotopes of the Stage 1 samples suggest three Precambrian episodes of juvenile crustal growth at 3.0 Ga, 2.5 Ga and 1.0 Ga, and a major crustal reworking at 580-500 Ma for the source areas, which are constraint to be northwestern India and its surrounding orogens. Together with other evidence, we propose that South China likely collided with northwestern India during the Gondwana assembly, generated the Bhimphedian orogeny in north India and formed two foreland basins on both the north India and South China sides. Far-field stress of the collision triggered the Ordovician-Silurian Wuyi-Yunkai orogeny in South China. The Stage 2-3 samples in the Nanhua basin of South China were shed

    This study investigated the distribution and determinants of HIV risks among married couples in North India. Gender inequality emerged as a potential driver of HIV risks in this region. Data collection took place in 2003 in a probability survey of 3385 couples living in India's most populous state - Uttar Pradesh - and Uttaranchal. Couples' analyses utilizing generalized estimating equations showed that compared with husbands, wives were less knowledgeable about HIV (OR = 0.31, 95% CI = 0.27-0.36), more likely to consider themselves at risk for infection (OR = 6.86, 95% CI = 4.65-10.13), and less likely to feel that a wife had the right to refuse sex with her husband (OR = 0.50, 95% CI = 0.44-0.58). The proportion of husbands reporting non-marital sex in the past year was 7.1% and transactional sex in the past year, 2.2%. Among their wives, 73.4% were unaware of their husbands' non-marital sexual behaviors and only 28.9% of husbands reported condom use during their last non-marital sexual encounter. Logistic regression analyses showed that husbands' alcohol use, husbands' mobility, and urban residence were positively associated with husbands' non-marital sexual behaviors adjusting for other covariates. The data demonstrate that HIV prevention programs among couples in North India should consider both sexual risks and gender inequalities which potentially fuel HIV spread in this region.

  2. Farmer's response to changing climate in North East India

    Diversification of land use in the cultivation of various crops provides an alternative way to moderate the climate risk. By choosing alternative crops that are resilient to various weather parameters, farmers can reduce the crop damage and achieve optimum output from their limited land resources. Apart from other adaptation measures, crop diversity can reflect farmers' response towards changing climate uncertainty. This paper tries to examine the changing climatic condition through spatio-temporal variation of two important weather variables (precipitation and temperature) in the largest North-East Indian state, Assam, since 1950. It is examined by the variation in crop diversification index. We have used (1) Herfindahl Index for measuring degree of diversification and (2) locational quotient for measuring the changes in the regional crop concentration. The results show that, in almost all the districts, crop specialization has been taking place slowly and that happened mostly in the last phase of our study. The hilly and backward districts recorded more diversification but towards lower value crops. It goes against the normal feature of crop diversification where farmers diversify in favour of high value crops. Employing ordinary least squares method and/or Fixed Effect model, irrigation is found to have significant impact on crop diversification; while the flood plain zones and hill zones are found to have better progress in this regard, which has been due to the survival necessity of poor farmers living the zone. Thus crop diversity does not reflect very significant response from the farmers' side towards changing weather factors (except rainfall) though they have significant impact on the productivity of various crops, and thus profitability. The study thus suggests the necessity for rapid and suitable diversification as alternative climate change mitigation in the long run.

    North Indian Muslim populations have historical, linguistic, and socioreligious significance to the Indian subcontinent. Although sociocultural and political dimensions of their demography are well documented, no detailed genetic structure of the populations is available. We have undertaken a survey of the gene frequencies of the ABO, Rh, PTC taste ability, sickling, and G6PD systems for different endogamous groups: Sheikh, Syed, Pathan, Ansari, Saifi, and Hindu Bania. All the groups at most loci showed statistically nonsignificant differences, except for ABO and PTC traits, for which interpopulational differences were seen. Heterozygosity ranged from 0.048 to 0.617 among the Sheikh, 0.149 to 0.599 among the Pathan, 0.105 to 0.585 among the Ansari, 0.25 to 0.869 among the Syed, 0.107 to 0.565 among the Saifi, and 0.100 to 0.492 among the Hindu Bania. The average D(ST) and G(ST) values for the five marker loci were 0.0625 +/- 0.098 and 0.1072 +/- 0.041, respectively. A dendrogram was constructed using the UPGMA clustering method. Our results revealed that the Pathan and the Sheikh form one cluster, the Syed and the Hindu Bania form another cluster, and the two clusters join together (the so-called higher caste); also, the Saifi and the Ansari form a separate cluster (lower caste). The results of the genetic distance analysis are useful for understanding the pattern of genetic relationships between different endogamous groups of Muslims.

    Mycetoma is chronic granulomatous infection of skin and subcutaneous tissue caused by both bacteria and fungi. We report a case of mycetoma caused by Scedosporium apiospermum in the right foot of a 45-year-old farmer in north India. The patient had a history of trauma in the sole of the right foot followed by discharge of white granules along with proximal progression. Scedosporium apiospermum was identified based on colony characteristics and microscopic features on slide culture. Mycetoma is a progressive disease. Foot is commonly affected in persons who walk barefoot, especially in south India. Untreated mycetoma progress and involve the underlying fasciae and tissues along with bones often resulting in loss of limb. By prompt and reliable diagnosis with corresponding antimicrobial administration, we can prevent further progression and limb disability.

    Using molecular genetic data on Aggarwals (Vaish/Vysya), an endogamous population group of north India, we provide evidence of its homogeneous unstratified population structure. We found the mean average heterozygosity value of 0.33 for 14 single nucleotide polymorphisms belonging to four genes (TCF7L2-, HHEX-, KCNJ11-, and ADIPOQ-) in the Aggarwal population (sample of 184 individuals) and tried to evaluate the genomic efficiency of endogamy in this population with the help of clan-based stratified analysis. We concluded that the sociocultural identity of the endogamous population groups could act as a robust proxy maker for inferring their homogeneity and population structure in India, which is ideal also for population selection for future genome-wide association studies in the country.

    The lack of epidemiologic data on invasive Streptococcus pyogenes infections in many developing countries is concerning, as S. pyogenes infections are commonly endemic in these areas. Here we present the results of the first prospective surveillance study of invasive Streptococcus pyogenes infections in India. Fifty-four patients with invasive S. pyogenes infections were prospectively enrolled at two study sites, one in the north and one in the south of India. Sterile-site isolates were collected, and clinical information was documented using a standardized questionnaire. Available acute-phase sera were tested for their ability to inhibit superantigens produced by the patient's own isolate using a cell-based neutralizing assay. The most common clinical presentations were bacteremia without focus (30%), pneumonia (28%), and cellulitis (17%). Only two cases of streptococcal toxic shock syndrome and no cases of necrotizing fasciitis were identified. Characterization of the isolates revealed great heterogeneity, with 32 different emm subtypes and 29 different superantigen gene profiles being represented among the 49 sterile-site isolates. Analyses of acute-phase sera showed that only 20% of the cases in the north cohort had superantigen-neutralizing activity in their sera, whereas 50% of the cases from the south site had neutralizing activity. The results demonstrate that there are important differences in both clinical presentation and strain characteristics between invasive S. pyogenes infections in India and invasive S. pyogenes infections in Western countries. The findings underscore the importance of epidemiologic studies on streptococcal infections in India and have direct implications for current vaccine developments. PMID:22357508

    Helicobacter pylori-related gastroduodenal diseases are very common in India. Antibiotic resistance to commonly used antibiotics against H. pylori is increasing very rapidly. The aim of this study was to determine the antimicrobial susceptibility patterns of H. pylori strains from India against commonly used antibiotics in H. pylori treatment. Helicobacter pylori were cultured from 68 patients suffering from various gastroduodenal diseases in North India. Minimum inhibitory concentrations (MICs) to different antibiotics were determined by agar dilution. The clinical diagnosis of the 68 patients who were H. pylori culture-positive were gastro-oesophageal reflux disease (GERD) (n=23), non-erosive reflux disease (NERD) (n=22), non-ulcer dyspepsia (NUD) (n=13), antral gastritis (n=3), duodenal ulcer (n=2) and others (n=5). Of the 68 H. pylori isolates, 20 (29.4%) showed no resistance. The prevalence of drug resistance was 70.6%, including resistance to metronidazole (48.5%), furazolidone (22.1%), amoxicillin (17.6%), tetracycline (16.2%) and clarithromycin (11.8%). Dual and multiple drug resistance were found in 26.5% and 8.8% of cases, respectively. In conclusion, more than two-thirds of the isolated H. pylori strains showed resistance to at least one of the antibiotics for H. pylori treatment. Metronidazole resistance was most prevalent amongst the isolates tested. Emergence of dual and multidrug resistance is of great concern and there is an urgent need for regular antibiotic resistance surveillance studies. Amoxicillin- and clarithromycin-based anti-H. pylori regimens commonly prescribed for triple therapy in India show least resistance and hence are appropriate for anti-H. pylori management in India.

    Coccidiosis, caused by apicomplexan parasites of the genus Eimeria, inflicts severe economic losses to the poultry industry around the globe. In the present study, ITS-1 based species specific nested PCR revealed prevalence of E. acervulina, E. brunetti, E. maxima, E. mitis, E. praecox, E. necatrix and E. tenella in 79.2%, 12.5%, 64.6%, 89.6%, 60.4%, 64.6% and 97.9% poultry farms of north India, respectively. The ITS-1 sequences of different Eimeria spp. from north India were generated and analyzed to establish their phylogenetic relationship. The sequence identity with available sequences ranged from 80 to 100% in E. tenella, 95 to 100% in E. acervulina, 64 to 97% in E. necatrix, 96 to 99% in E. brunetti and 97 to 98% in E. mitis. Only long ITS-1 sequences of E. maxima could be generated in the present study and it had 80-100% identity with published sequences. Two out of the four ITS-1 sequences of E. maxima had mismatches in the published nested primer sequences from Australia, while one sequence of E. necatrix had a mismatch near 3' end of both forward and reverse published nested primer sequences, warranting for the need of designing new set of degenerate primers for these two species of Eimeria. In the phylogenetic tree, all isolates of E. acervulina, E. brunetti, E. mitis, E. tenella and E. necatrix clustered in separate clades with high bootstrap value. E. maxima sequences of north Indian isolates grouped in a long form of E. maxima clade. Complete ITS-1 sequences of E. necatrix and E. mitis are reported for the first time from India. Further studies are required with more number of isolates to verify whether these differences are unique to geographical locations.

    Antigen Dd, a polymorphic antigen found in extracts of certain human dandruff specimens, was investigated in five caste groups of north India. The incidence of antigen Dd-positive type varied from 21.21 per cent in Brahmins to 29.08 per cent in the Jat Sikhs of Punjab. However, a high frequency (45%) was observed in the Sunni Muslims of Kashmir, which differed significantly, when compared with different caste groups of Punjab. Family studies on 44 families indicated its inherited nature, the mode of inheritance being autosomal dominant.

    Childhood cancers are relatively uncommon in comparison to adult cancers. There is no literature available to shed light on clinic-pathological types and patterns of care for childhood cancers in our population in North-East India. In this analysis we therefore tried to determine the common childhood cancers diagnosed in our institute, clinical profile of the patients, types of treatment and compliance, and median survival estimates. Leukemia was most common, followed by retinoblastoma, central nervous system tumours and lymphomas. Ascertaining the clinic-pathological profile of childhood cancers in our population is essential for allocation and management of resources for this small but important group of patients.

  12. Tension Among Women in North India: An Idiom of Distress and a Cultural Syndrome.

    PubMed

    Weaver, Lesley Jo

    2017-03-01

    The existing literature on Indian ethnopsychology has long asserted that somatization is a key aspect of experiences of distress. The study of idioms of distress arose out of work done in India (Nichter in Cult Med Psychiatry 5(4):379-408, 1981), but ironically, little subsequent work has systematically explored idioms of distress in this part of the world. This ethnographic study focused on the term tension (tenśan) and its relation to a cultural syndrome among women in urban North India. This syndrome appears to involve rapid-onset anger, irritation, rumination, and sleeplessness as key symptoms. It is often linked to specific circumstances such as domestic conflict and is associated with the stresses of modern urban life. People who report more symptoms of tension had consistently higher scores on the Hopkins Symptoms Checklist-25 for depression and anxiety. In this cultural context where psychiatric care is highly stigmatized, the language of tension can aid providers of mental healthcare (many of whom, in India, are not psychiatrists or psychologists) to identify and communicate effectively with potential patients whose mental healthcare needs might otherwise go unaddressed.

    Moyamoya disease is a chronic progressive cerebrovascular disorder, characterized by stenosis or occlusion of bilateral internal carotid arteries (ICAs), anterior cerebral arteries (ACAs) and middle cerebral arteries (MCAs), accompanied by a collateral network of vessels formed at the base of the brain. Ischemia and intracranial hemorrhage are the common typical manifestations. However moyamoya disease has been associated with atypical presentations like headache, seizures and involuntary movements. Although frequently reported from Asian countries like Japan, China and Korea, only few studies reported on clinical manifestations of moyamoya disease from India. To study the varied presentations of moyamoya disease in a tertiary care hospital of north-east India. Relevant investigations were done to rule out other causes of moyamoya syndrome. We report 6 cases of moyamoya disease with varied presentations from a tertiary care referral government hospital. Case 1, 2 and 6 presented with alternating hemiparesis. Case 3 had amaurosis fugax. Case 4 had history suggestive of ischemic stroke and presented with hemichorea. Case 4 had focal seizure as the only manifestation. Cases 4 and 5 notably had stenosis of posterior cerebral artery (PCA) in addition to stenosis of bilateral ICAs, ACAs and MCAs. Owing to its low incidence in India, moyamoya disease is easily overlooked as a possible diagnosis. However, because of its progressive nature, it is imperative to diagnose this disease early and offer surgical treatment to the patients.

    Selection potential based on differential fertility and mortality has been computed for six tribal groups inhabiting different geo-climatic conditions, namely: Sahariya, Mina and Bhil of the State of Rajasthan, north-western India, and Munda, Santal and Lodha of the State of West Bengal, eastern India. Irrespective of the methodology, the total index of selection was found to be highest among Lodhas (0.668), followed by Sahariyas (0.524), Santals (0.462), Bhils (0.386), Mundas (0.353) and Minas (0.334). Incidentally, Lodha and Sahariya are two of the seventy-four notified primitive tribal groups of India, and these two study populations show the highest index of total selection, mainly because of a higher embryonic and postnatal mortality. The relative contribution of the fertility component to the index of total selection is higher than the corresponding mortality component in all tribal groups. The analysis of postnatal mortality components indicates that childhood mortality constitutes the bulk of postnatal mortality, suggesting that children under 5 years need better health care in these tribal groups.

    Wolfram syndrome, also known as DIDMOAD, is a relatively rare inherited neurodegenerative disorder, first evident in childhood as an association of juvenile-onset diabetes mellitus and optic atrophy, followed by diabetes insipidus and deafness. The aim of the study was to examine the clinical profile of patients with DIDMOAD syndrome presenting to a tertiary care hospital in north India. Clinical presentation of juvenile-onset diabetes mellitus fulfilling the diagnosis of Wolfram syndrome was studied using a prepared standardized form. Subjects with juvenile-onset non-autoimmune diabetes mellitus attending the diabetic clinic at a tertiary care centre in north India were followed for 10 years and a diagnosis of fully developed Wolfram syndrome was confirmed in seven individuals. The series consisted of five male and two female patients with a mean age of 17.5 ±7.34 years. Two subjects had consanguinity and none had any other family member affected. Optic atrophy was present in all, sensorineural hearing loss in 4/7, central diabetes insipidus in 4/7 and nephrogenic diabetes insipidus in 2/7 subjects. The new associations found were: spastic myoclonus, short stature with pancreatic malabsorption, nephrogenic diabetes insipidus, cyanotic heart disease and choledocholithiasis with cholangitis. Genetic analysis revealed mutation in exon 8 of the WFS1 gene in all the cases studied. The present clinical series of Wolfram syndrome reveals a varied clinical presentation of the syndrome and some new associations. © 2011 The Authors. Diabetic Medicine © 2011 Diabetes UK.

    Gastrointestinal parasitic infection is highly prevalent in the North Eastern States (NEH) of India and accounted for significant economic losses across various livestock species. Productivity of cattle in terms of milk yield was estimated to be considerably higher (3,715, 3,590, and 3,154 L) due to strategic anthelmintic treatment as compare to control group (2,928 L). Based on the probability of occurrence of parasitic infection as well as increase in value of milk production, the possible economic gain at state level has been estimated to be Rs. 46 million, Rs. 35 million, and Rs. 14 million, depending upon the different strategic treatment. The government may take up the program to educate the cattle farmers on strategic management against parasitic infection and simultaneously making available various anthelmintic medicines. This public responsibility of the government to minimize the risk and economic loss due to gastrointestinal parasite infection may reduce the private cost and thereby would increase the social benefits in North Eastern states of India.

    Context Gender inequality is a long-recognized driver of the HIV epidemic. However, few studies have investigated the association between gender-based power and HIV risk in India, which has the world's third largest HIV epidemic. Methods Population-based data collected in 2003 from 3,385 couples residing in Uttar Pradesh and Uttarakhand, North India, were used to examine associations between gender-based power (wife's autonomy and husband's inequitable gender attitudes) and indicators of couples' HIV risk (whether the husband had had premarital sex with someone other than his eventual spouse, extramarital sex in the past year or STI symptoms in the past year). Structural equation modeling was used to create composite variables for the gender-based power measures and test their associations with HIV risk measures. Results Twenty-four percent of husbands had had premarital sex, 7% had had extramarital sex in the past year and 6% had had STI symptoms in the past year. Structural equation models indicated that wives who reported higher levels of autonomy were less likely than other wives to have husbands who had had extramarital sex in the past year (direct association) and STI symptoms in the past year (indirect association). Moreover, husbands who endorsed more inequitable gender attitudes were more likely than others to report having had premarital sex with someone other than their spouse, which in turn was associated with having had extramarital sex and STI symptoms in the past year. Conclusions If the associations identified in this study reflect a causal relationship between gender-based power and HIV risk behavior, then HIV prevention programs that successfully address inequitable gender roles may reduce HIV risks in North India.

    Aluminum (Al) is the third most abundant metal in earth crust, whose chemical form is mainly dependent on soil pH. The most toxic form of Al with respect to plants is Al3+, which exists in soil pH <5. Acidic soil significantly limits crop production mainly due to Al3+ toxicity worldwide, impacting approximately 50% of the world's arable land (in North-Eastern India 80% soil are acidic). Al3+ toxicity in plants ensues root growth inhibition leading to less nutrient and water uptake impacting crop productivity as a whole. Rice is one of the chief grains which constitutes the staple food of two-third of the world population including India and is not untouched by Al3+ toxicity. Al contamination is a critical constraint to plant production in agricultural soils of North East India. 24 indigenous Indica rice varieties (including Badshahbhog as tolerant check and Mashuri as sensitive check) were screened for Al stress tolerance in hydroponic plant growth system. Results show marked difference in growth parameters (relative growth rate, Root tolerance index, fresh and dry weight of root) of rice seedlings due to Al (100 μM) toxicity. Al3+ uptake and lipid peroxidation level also increased concomitantly under Al treatment. Histochemical assay were also performed to elucidate uptake of aluminum, loss of membrane integrity and lipid peroxidation, which were found to be more in sensitive genotypes at higher Al concentration. This study revealed that aluminum toxicity is a serious harmful problem for rice crop productivity in acid soil. Based on various parameters studied it's concluded that Disang is a comparatively tolerant variety whereas Joymati a sensitive variety. Western blot hybridization further strengthened the claim, as it demonstrated more accumulation of Glutathione reductase (GR) protein in Disang rice variety than Joymati under stressed condition. This study also observed that the emergence of lethal toxic symptoms occurs only after 48h irrespective of the dose

  1. Indo-Asian collision in the Sikkim-Bhutan Himalaya

    Compared to the central Himalaya, the seismogenic potential of Bhutan has been enigmatic due to its lower than average background seismicity, the absence of a reliable historical record, and its unusual location near the Shillong plateau, where a Mw=8.1 earthquake in 1897 resulted in ≈10 m of N/S shortening of the Indian plate to its south. The GPS velocity field measured thrice between 2003 and 2012 provides new insights that permit us to constrain details of loading and collisional geometry. We find that a 90±10 km wide décollement below Sikkim and Bhutan is being loaded at rates of 20±2 mm/year. The locking line lies at approximately 20 km depth and, as in the Himalaya to the west, approximately follows the smoothed 3.5 km contour. Convergence across the Shillong plateau is less than 7 mm/yr. The GPS data suggest that the Brahmaputra valley is rotating clockwise at 0.02±0.1 rad/yr, which is inferred to have the effect of reducing the stressing rate in the Aranuchal Himal. Although a small circle closely defines the Himalayan arc west of 87°E, the Sikkim-Bhutan Himalaya can be approximated by a 500 km linear east-west segment between 87°E and 92°E, terminated by a 10°± change in strike near the 1934 rupture in the west, and by a 20° change in strike at the start of the 400-km-long Arunachal Pradesh segment to the east. Paleoseismic studies to the east and west of Bhutan suggest that a great earthquake may have ruptured this 500 km segment of the arc with 18 m of slip c.1100 AD (Kumar et al., 2011) suggesting that the current slip deficit may be close to that which prevailed before the 1100 earthquake. Thus if no intervening great earthquake has occurred in the Bhutan Himalaya since 1100, the 500 km x100 km area Sikkim/Bhutan segment could slip 18 m at present in a 8.6

    The Siyom Valley section in eastern Arunachal Pradesh exposes an inverted metamorphic succession (Nandini & Thakur, 2011), metapelitic assemblages increasing in grade northwards from chlorite, through biotite, garnet-staurolite and kyanite-bearing schist to kyanite-sillimanite migmatite. Grade changes are mostly controlled by shallowly north, and northwest-dipping fault structures. Two textural stages of garnet growth can be identified in the ilmenite-bearing amphibolite facies rocks, staurolite having formed late in, or after, deformation responsible for the main penetrative foliation (S2). Kyanite and rutile inclusions in garnet indicate that their growth in migmatite preceded that of matrix sillimanite, ilmenite and cordierite, though unrecrystallized kyanite is also common in the feldspathic matrix. Preliminary data indicate the pronounced tectonic thinning of metasedimentary protoliths during exhumation, and the probability of a pronounced step in grade in the middle part of the river section. Similarities with sections in the Sikkim (Dasgupta et al., 2004) and western Arunachal Pradesh (Goswami et al., 2009) Himalaya reflect the lateral continuity of the south-vergent thrusts that controlled the exhumation of the high-grade rocks, with debate concerning the location and significance of the Main Central Thrust zone begging protolith and metamorphic age data.

    To understand the genetic diversity of Mycobacterium avium subspecies paratuberculosis (MAP) isolates recovered from domestic and wild ruminants, commercial milk, and human beings in North India. Genotyping of MAP isolates (N=117) recovered from animals, commercial milk, and human beings in different regions of North India between 1998 and 2007 was carried out using IS1311 PCR-restriction enzyme analysis (REA) and short sequence repeat (SSR) typing (G and GGT repeat loci). Of the 117 MAP isolates recovered from North India, bison-type was the predominant (83.8%) genotype followed by cattle-type (16.2%). Bison-type was the exclusive genotype recovered from goats, sheep, buffaloes, and blue bulls. However, both bison-type and cattle-type genotypes were recovered from cattle, humans, and commercial bovine milk samples. The relative distribution of the two genotypes was different in the different regions. Bison-type was the major genotype at the Central Institute for Research on Goats (CIRG), Akos, Ajmer, and Mathura, whereas, cattle-type was the major genotype from New Delhi and Agra. SSR typing of these isolates revealed that all MAP bison-type isolates had an identical profile (7g4ggt) with respect to G and GGT repeat SSR loci. In this study the sheep-type genotype was not found in North India. This study is the first from India to report the presence of two kinds of MAP genotypes (cattle-type and bison-type). However, non-reporting of the sheep-type genotype may not mean that it is absent in North India; the use of multiple culture media to recover MAP from clinical samples for future investigations is advised.

    The geology of the Kangchenjunga-Darjeeling profile in west Sikkim and north Bengal is consistent with the interpretation of the High Himalaya metamorphic sequence as a ductile channel approximately 15-20 km thick, extruding southwards, bounded by major ductile shear zones above (South Tibetan Detachment) and below (Main Central Thrust zone). In the Yoksam to Kangchenjunga section the entire slab is composed of migmatites or leucogranite sheets. Massive sills, or sub-horizontal to gently north-dipping sheets, of leucogranite make up the entire Kangchenjunga massif and extend west at least as far as Jannu. Shear sense indicators show both pure shear flattening fabrics and non-coaxial south-directed simple shear fabrics. The carapace of the melt-filled channel is seen around the southern margin of the Singallila ridge and the Darjeeling klippe, where inverted metamorphic isograds from sillimanite+K-feldspar grade down through kyanite and staurolite to garnet-biotite grade have been well documented. We present an interpretation of the crustal structure of the Sikkim Himalaya, based on field structural observations and utilizing the INDEPTH seismic profile to constrain sub-surface structure to the north. We suggest that widespread melting within sillimanite grade gneisses, triggered sudden and rapid ductile extrusion during the Miocene, by critically affecting the rheology of the middle crust under south Tibet. Leucogranite melts lubricated shear zones, facilitating rapid transport of heat towards the surface. When the leucogranite melts began to cool, ductile extrusion ended, as thrusting propagated down-section into the Lesser Himalaya. Since leucogranite expulsion was largely horizontal, rather than vertical, and since the STD normal sense shear zone is very low-angle, dipping to the north, decompression melting cannot be invoked as an origin for the leucogranites. The heat source for such widespread melting at such shallow levels in the crust can only be explained

    Physical features and somatometric characters of the wide spread Gujjar population in North-Western India are fascinating. It is all the more interesting to study their morphological and regional variations in the body dimensions. In this paper, anthropometric characters of 200 adult subjects each belonging to Hindu Gujjars in the Ropar District of Punjab and Muslim Gujjars in the Chamba District of Himachal Pradesh in the North-Western part of India were compared. They differ significantly from each other for many physiognomic measurements, suggesting the biological diversity between the two population groups. Further, the comparison of anthropometric measurements between the different localities of the Gujjars showed morphological variations and regional diversity of the isolates in North-Western India. These findings may be attributed to the founder effect, genetic drift, and breeding and geographical isolation of the populations under study and not to secular trends. The findings have also been compared and discussed with the available results of other local populations in North-Western India.

    This study aims to assess the adequacy level of radiological protection systems available in the diagnostic radiology facilities located in three capital cities of North East (NE) India. It further attempts to understand, using a multi-disciplinary approach, how the safety codes/standards in diagnostic radiology framed by the Atomic Energy Regulatory Board (AERB) and the International Atomic Energy Agency (IAEA) to achieve adequate radiological protection in facilities, have been perceived, conceptualized, and applied accordingly in these facilities. About 30 diagnostic radiology facilities were randomly selected from three capitals of states in NE India; namely Imphal (Manipur), Shillong (Meghalaya) and Guwahati (Assam). A semi-structured questionnaire developed based on a multi-disciplinary approach was used for this study. It was observed that radiological practices undertaken in these facilities were not exactly in line with safety codes/standards in diagnostic radiology of the AERB and the IAEA. About 50% of the facilities had registered/licensed x-ray equipment with the AERB. More than 80% of the workers did not use radiation protective devices, although these devices were available in the facilities. About 85% of facilities had no institutional risk management system. About 70% of the facilities did not carry out periodic quality assurance testing of their x-ray equipment or surveys of radiation leakage around the x-ray room, and did not display radiation safety indicators in the x-ray rooms. Workers in these facilities exhibited low risk perception about the risks associated with these practices. The majority of diagnostic radiology facilities in NE India did not comply with the radiological safety codes/standards framed by the AERB and IAEA. The study found inadequate levels of radiological protection systems in the majority of facilities. This study suggests a need to establish firm measures that comply with the radiological safety codes/standards of the

    We present the results of a broadband magnetotelluric survey along a 200-km-long profile across the Sikkim Himalaya. The data were acquired at average station spacing of 5-6 km and transfer functions of 31 sites in 0.01-1000 s period range have been used for 2-D joint inversion of TE and TM modes. The composite model incorporating the effect of transverse strike reveals several features that correlate with the available seismic and kinematic models of the region. A major result of the present study is that the Main Himalayan Thrust forms the base of several resistive blocks within the wedge and that a ramp structure is present south of the Main Central Thrust Zone (MCTZ). Another significant result is that the crust and mantle lithosphere beneath the MCTZ and the Higher Himalayan Crystallines (HHC) seem to be compositionally/geologically different from the lithosphere south of the MCTZ. A steep crustal-scale fault with the Moho offset of 14 km is inferred to be separating these two blocks. The deep crustal seismicity could be related to this fault whereas shallow seismicity can be linked to the deformation within the wedge. The results also reveal the presence of some more conductors. We relate the conductor within the HHC to the sedimentary rocks of the Tethyan sequence exposed in a window about 40 km west of the profile and north of the South Tibetan Detachment System (STDS). The conductor at 90 km profile location is linked to the Gondwana rocks exposed in the Rangit Window. A 4-6 km thick sedimentary layer overlies the basement in the Gangetic foreland basin. We also delineate a sub-crustal conductor at 50-60 km depth beneath the foreland basin at the southern end of the profile, the cause of which is not apparent and needs to be explored.

    Entamoeba histolytica is an intestinal parasite causing significant morbidity and mortality in the developing world. More tools are needed to understand the epidemiology and molecular pathogenesis of amebiasis. Virulence pattern of E. histolytica could be linked with the genotype of a strain. Several loci showing insertion polymorphism of retrotransposable short interspersed nuclear elements EhSINE1 and EhSINE2 have been reported among laboratory strains of E. histolytica. The present study was undertaken to validate this observation in clinical isolates from north India. Our results indicate that the Indian samples show a different propensity of SINE retention or loss at two of the polymorphic loci compared with non-Indian samples. Statistical analysis of different loci revealed Locus 17 of EhSINE1as a potential geographical marker for distinguishing Indian isolates from non Indian isolates. Copyright © 2017 Elsevier Inc.

    Abstract Ten Citrus (Linnaeus, 1753) species of North-East India have been karyo-morphologically analysed. All studied species had 2n=18 chromosomes without any evidence of numerical variation. All the chromosomes were found to be of metacentric and sub-metacentric in all the species; the morphology of the chromosomes showing size difference only. Symmetrical karyotype which does not have much difference in the ratio of longest to shortest chromosome in all the species was observed. Three species, Citrus grandis (Osbeck, 1757), Citrus reticulata (Blanco, 1837) and Citrus medica (Linnaeus, 1753) are identified as true basic species from asymmetry studies of karyotypes as they reflect on the primitive nature of their genomes. Citrus indica (Tanaka, 1937)occupies a special taxonomic position within the genus Citrus as a progenitor for other cultivated species. PMID:24260635

    Engineering seismoscope data collected at distances less than 300 km for the M 7.7 Bhuj, India, mainshock are compatible with ground-motion attenuation in eastern North America (ENA). The mainshock ground-motion data have been corrected to a common geological site condition using the factors of Joyner and Boore (2000) and a classification scheme of Quaternary or Tertiary sediments or rock. We then compare these data to ENA ground-motion attenuation relations. Despite uncertainties in recording method, geological site corrections, common tectonic setting, and the amount of regional seismic attenuation, the corrected Bhuj dataset agrees with the collective predictions by ENA ground-motion attenuation relations within a factor of 2. This level of agreement is within the dataset uncertainties and the normal variance for recorded earthquake ground motions.

  15. Comparison of Archean and Phanerozoic granulites: Southern India and North American Appalachians

    Archean granulites at the southern end of the Dharwar craton of India and Phanerozoic granulites in the southern Appalachians of North America share an important characteristic: both show continuous transitions from amphibolite facies rocks to higher grade. This property is highly unusual for granulite terranes, which commonly are bounded by major shears or thrusts. These two terranes thus offer an ideal opportunity to compare petrogenetic models for deep crustal rocks formed in different time periods, which conventional wisdom suggests may have had different thermal profiles. The salient features of the Archean amphibolite-to-granulite transition in southern India have been recently summarized. The observed metamorphic progression reflects increasing temperature and pressure. Conditions for the Phanerozoic amphibolite-to-granulite transition in the southern Appalachians were documented. The following sequence of prograde reactions was observed: kyanite = sillimanite, muscovite = sillimanite + K-feldspar, partial melting of pelites, and hornblende = orthopyroxene + clinopyroxene + garnet. The mineral compositions of low-variance assemblages in mafic and intermediate rocks are almost identical for the two granulite facies assemblages. In light of their different fluid regimes and possible mechanisms for heat flow augmentation, it seems surprising that these Archean and Phanerozoic granulite terranes were apparently metamorphosed under such similar conditions of pressure and temperature. Comparison with other terrains containing continuous amphibolite-to-granulite facies transitions will be necessary before this problem can be addressed.

    A tertiary care hospital in North India. To determine the prevalence of different genotypes and examine their association with drug resistance among clinical isolates of Mycobacterium tuberculosis from the northern region of India. We analysed 100 clinical isolates of M. tuberculosis using mycobacterial interspersed repetitive units genotyping and TbD1 analysis. The analysis revealed that 34% of strains belonged to the Delhi/CAS (TbD1-) lineage, 32% had unknown patterns (27 TbD1-, 5 TbD1+), 18% were of Beijing genotype (TbD1-) and 11% were of EAI lineages (TbD1+). Twenty-one strains were multidrug-resistant tuberculosis (MDR-TB), 9 of which belonged to the Delhi/CAS lineage, 4 were of Beijing lineage, 6 were of unknown pattern and one was of EAI lineage. Our meta-analysis showed the overall proportion of CAS lineage to be 42.96% (95%CI 33-52); the CAS lineage had no association with MDR-TB (OR 0.89, 95%CI 0.66-1.20). The study highlights the high proportion of CAS lineage strains and absence of association with MDR-TB. The distribution and identification of different genotypes of M. tuberculosis could help in better understanding the factors that influence disease transmission and drug resistance.

    The purpose of this work was to study the explanatory models of patients with first episode depression presenting to a tertiary care hospital located in North-western India. One hundred sixty four consecutive patients with diagnosis of first episode depression (except severe depression with psychotic symptoms) according to the International Classification of Diseases-10th Revision (ICD-10) and ≥18 years of age were evaluated for their explanatory models using the causal models section of Explanatory Model Interview Catalogue (EMIC). The most common explanations given were categorized into Karma-deed-heredity category (77.4%), followed by psychological explanations (62.2%), weakness (50%) and social causes (40.2%). Among the various specific causes the commonly reported explanations by at least one-fourth of the sample in decreasing order were: will of god (51.2%), fate/chance (40.9%), weakness of nerves (37.8%), general weakness (34.7%), bad deeds (26.2%), evil eye (24.4%) and family problems (21.9%). There was some influence of sociodemographic features on the explanations given by the patients. From the study, it can be concluded that patients with first episode depression have multiple explanatory models for their symptoms of depression which are slightly different than those reported in previous studies done from other parts of India. Understanding the multiple explanatory models for their symptoms of depression can have important treatment implications. Copyright © 2012 Elsevier B.V. All rights reserved.

    Malaria is endemic and a major public health problem in north east (NE) region of India and contributes about 8-12 % of India's malaria positives cases. Historical morbidity pattern of malaria in terms of API (Annual Parasite Incidence) in the state of Assam has been used for delineating the malaria incidence hotspots at health sub centre (HSC) level. Strong spatial autocorrelation (p < 0.01) among the HSCs have been observed in terms of API (Annual Parasite Incidence). Malaria incidence hot spots in the state could be identified based on General G statistics and tested for statistical significance. Spatial correlation of malaria incidence hotspots with physiographic and climatic parameters across 6 agro-climatic zones of the state reveals the types of land cover pattern and the range of elevation contributing to the malaria outbreaks. Analysis shows that villages under malaria hotspots are having more agricultural land, evergreen/semi-evergreen forests with abundant waterbodies. Statistical and spatial analyses of malaria incidence showed a significant positive correlation with malaria incidence hotspots and the elevation (p < 0.05) with villages under malaria hotspots are having average elevation ranging between 17 to 240 MSL. This conforms to the characteristics of two dominant mosquito species in the state Anopheles minimus and An. baimai that prefers the habitat of slow flowing streams in the foot hills and in forest ecosystems respectively.

    Aim: We evaluated the distribution HBV genotypes among non-remunerated healthy blood donors in eastern North India. Materials and Methods: During screening of donated blood, 176 consecutive HBsAg positive, samples comprised the study. HBV-DNA was quantitative detected in 150 samples by PCR. HBV genotype was determined by identifying genotype-specific DNA band using nested PCR. Results: Majorities were of age group 31-40 yrs (65.3%). Males (92.7%) outnumbered females (7.3%) and were HbeAg-negative HBsAg carriers. Over all, genotype-A was the most prevalent (54%) followed by D (21.3%). We did not find genotype-G and H. Districts under study, divided into four zones: Zone–I genotype-A was most common (62.3%) followed by D (18.8%); Zone–II genotype–C (41.2%) was more frequent followed by D (20.6% and A (17.7%). Zone–III in adjoining Bihar state close to Zone–I, A was more prevalent (81.8%) followed by B and C (9.1%). In Zone-IV adjoining Zone- II had genotype-A (100%) only. Genotype–D had more sporadic distribution. Genotype-E and F were prevalent in Zone I and II (3/150, 2%). Conclusions: Among blood donors HBV genotype-A followed by D was the most prevalent in eastern North India. Genotype–A had pattern of distribution signifying common focus, while D was more sporadic and C had single large pocket (Zone-II) probably common focus but restricting to particular area. Evidences are suggestive of association of HBV genotype in liver dysfunction. An effective treatment and preventive strategies based of genotypes will reduce the disease burden and increase the blood safety. PMID:21897593

    Aim: Health professionals especially the dental professional are the frequent targets of musculoskeletal disorders (MSD). Complementary and alternative medicine (CAM) can be of some help in managing these MSD especially in. The purpose of this study was to determine the prevalence of CAM therapies as a treatment modality for MSD management among dental professionals of north India. Materials and Methods: Registered dentist of North Indian origin, India (n = 3598) were included in the study. The questionnaire was sent to all the dentists which consisted of the demographic profile, MSD in the past year, CAM therapies utilization and opinion about CAM therapies. Data analysis was done using SPSS version 21 and data were presented in tabular and graphic form. Test of significance was done using chi-square statistics with P < 0.05 considered as significant. Results: A response rate of 80% (n = 2879) was obtained, and all complained of MDS in some or the other part of their life. The use of CAM was reported among 70% (n = 2015) of the dentist who suffered from MSD. Other dentists either used conventional treatment or did not use anything. Conclusion: As the name implies, alternative medical systems is a category that extends beyond a single modality and refers to an entire system of theory and practice that developed separately from conventional medicine. CAM should be subject to rigorous scientific inquiry so that interventions that work are systematically distinguished from those that do not. In addition, the use of CAM treatments should be based on evidence of effectiveness and safety as demonstrated in randomized clinical trials. PMID:26692749

    The state of Punjab in the North-West part of India has acted as the main passage for all the major human invasions into the Indian subcontinent. It has resulted in the mixing of foreign gene pool into the local populations, which led to an extensive range of genetic diversity and has influenced the genetic structure of populations in Punjab, North-West India. The present study was conducted to examine the genetic structure, relationships, and extent of genetic differentiation in five Indo-European speaking ethnic groups of Punjab. A total of 1021 unrelated samples belonging to Banias, Brahmins, Jat Sikhs, Khatris, and Scheduled castes were analyzed for four human-specific Ins/Del polymorphic loci (ACE, APO, PLAT, and D1) and three restriction fragment length polymorphisms ESR (PvuII), LPL (PvuII), and T2 (MspI) using Polymerase chain reaction (PCR). All the loci were found to be polymorphic among the studied populations. The frequency of the Alu insertion at APO locus was observed to exhibit the highest value (82.6-96.3 %), whereas D1 exhibited the lowest (26.5-45.6 %) among all the ethnic groups. The average heterozygosity among the studied populations ranged from 0.3816 in Banias to 0.4163 in Khatris. The FST values ranged from 0.0418 to 0.0033 for the PLAT and LPL loci, respectively, with an average value being 0.0166. Phylogenetic analysis revealed that Banias and Khatris are genetically closest to each other. The Jat Sikhs are genetically close to Brahmins and are distant from the Banias. The Jat Sikhs, Banias, Brahmins, and Khatris are genetically very distant from the Scheduled castes. Overall, Uniform allele frequency distribution patterns, high average heterozygosity values, and a small degree of genetic differentiation in this study suggest a genetic proximity among the selected populations. A low level of genetic differentiation was observed in the studied population groups indicating that genetic drift might have been small or negligible in shaping

    Background The north-east Indian states of Manipur and Nagaland are two of the six high HIV prevalence states in the country, and the main route of HIV transmission is injecting drug use. Understanding the pathways to injecting drug use can facilitate early intervention with HIV prevention programs. While several studies of initiation into injecting drug use have been conducted in developed countries, little is known about the situation in developing country settings. The aim of this study was to increase understanding of the contextual factors associated with initiation into injecting drug use in north-east India, and the influence of these factors on subsequent initiation of others. Method In mid 2006 a cross-sectional survey among 200 injecting drug users (IDUs) was undertaken in partnership with local NGOs that provide HIV prevention and care services and advocacy for IDUs in Imphal, Manipur and Dimapur, Nagaland. The questionnaire elicited detailed information about the circumstances of the first injection and the contexts of participants' lives. Demographic information, self-reported HIV status, and details about initiation of others were also recorded. Results Initiation into injecting drug use occurred at 20 years of age. The drugs most commonly injected were Spasmo-proxyvon (65.5%) and heroin (30.5%). In 53.5% cases, a needle belonging to someone else was used. Two-thirds (66.7%) had used the drug previously, and 91.0% had known other IDUs prior to initiation (mean = 7.5 others). The first injection was usually administered by another person (94.5%), mostly a friend (84.1%). Initiation is a social event; 98% had others present (mean = 2.7 others). Almost 70% of participants had initiated at least one other (mean = 5 others). Initiation of others was independently associated with being male and unemployed; having IDU friends and using alcohol around the time of initiation; and having been taught to inject and not paid for the drug at the time of initiation

    Valeriana jatamansi, a medicinally important species of the family Valerianaceae, has been cytologically studied in different geographical areas of North-Western Himalayan region of India. The tetraploid cytotype with chromosome numbers 2n=32 is in conformity with the earlier reports of the species from different parts of the world. An octoploid cytotype (2n=64) makes a new addition for the species on a worldwide basis, whereas the diploid cytotype (2n=16) is new to India have been reported for the first time in India. These cytotypes (2n=16, 32, 64) show significant variations with respect to morphology as well as geographical distribution in the Western Indian Himalayas. Further, anomalous populations have been marked with meiotic abnormalities in the form of cytomixis, chromosomal stickiness, unoriented bivalents, formation of laggards and bridges resulting in abnormal microsporogenesis, and production of heterogeneous-sized fertile pollen grains along with reduced pollen fertility.

    Abstract The northeast region of India is one of the world’s most significant biodiversity hotspots. One of the richest bird areas in India, it is an important route for migratory birds and home to many endemic bird species. This paper describes a literature-based dataset of species occurrences of birds of northeast India. The occurrence records documented in the dataset are distributed across eleven states of India, viz.: Arunachal Pradesh, Assam, Bihar, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, Uttar Pradesh and West Bengal. The geospatial scope of the dataset represents 24 to 29 degree North latitude and 78 to 94 degree East longitude, and it comprises over 2400 occurrence records. These records have been collated from scholarly literature published between1915 and 2008, especially from the Journal of the Bombay Natural History Society (JBNHS). The temporal scale of the dataset represents bird observations recorded between 1909 and 2007. The dataset has been developed by employing MS Excel. The key elements in the database are scientific name, taxonomic classification, temporal and geospatial details including geo-coordinate precision, data collector, basis of record and primary source of the data record. The temporal and geospatial quality of more than 50% of the data records has been enhanced retrospectively. Where possible, data records are annotated with geospatial coordinate precision to the nearest minute. This dataset is being constantly updated with the addition of new data records, and quality enhancement of documented occurrences. The dataset can be used in species distribution and niche modeling studies. It is planned to expand the scope of the dataset to collate bird species occurrences across the Indian peninsula.

    Objectives Preventable neonatal mortality due to tetanus infection remains common. We aimed to examine antenatal vaccination impact in a context of continuing high neonatal mortality in rural northern India. Methods and Findings Using the third round of the Indian National Family Health Survey (NFHS) 2005–06, mortality of most recent singleton births was analysed in discrete-time logistic model with maternal tetanus vaccination, together with antenatal care utilisation and supplementation with iron and folic acid. 59% of mothers reported receiving antenatal care, 48% reported receiving iron and folic acid supplementation and 68% reported receiving two or more doses of tetanus toxoid (TT) vaccination. The odds of all-cause neonatal death were reduced following one or more antenatal dose of TT with odds ratios (OR) of 0.46 (95% CI 0.26 to 0.78) after one dose and 0.45 (95% CI 0.31 to 0.66) after two or more doses. Reported utilisation of antenatal care and iron-folic acid supplementation did not influence neonatal mortality. In the statistical model, 16% (95% CI 5% to 27%) of neonatal deaths could be attributed to a lack of at least two doses of TT vaccination during pregnancy, representing an estimated 78,632 neonatal deaths in absolute terms. Conclusions Substantial gains in newborn survival could be achieved in rural North India through increased coverage of antenatal TT vaccination. The apparent substantial protective effect of a single antenatal dose of TT requires further study. It may reflect greater population vaccination coverage and indicates that health programming should prioritise universal antenatal coverage with at least one dose. PMID:23152814

    Background: Some medical doctors in India have publicly expressed opposition to making emergency contraceptive pills (ECPs) easily accessible, even though ECPs are included in the method mix of the Ministry of Health and Family Welfare program and as an over-the-counter (OTC) product. Such opposition affects access to ECPs by influencing policy, procurement, and distribution, besides stigmatizing the ECP user. This study was conducted to assess ECP knowledge, attitudes, and practices of doctors in North India. Methods: A cross-sectional survey of 83 doctors who provide ECPs, randomly selected from 3 cities in the state of Uttar Pradesh, was conducted in 2011. The quantitative data were complemented by 19 in-depth interviews with purposively selected senior gynecologists and other opinion leaders. Results: All surveyed physicians cited the correct dose and regimen for ECPs. However, the large majority of those surveyed believed that ECPs work by preventing implantation. (The best evidence currently indicates that ECPs do not work by preventing implantation.) Most doctors also believed incorrectly that ECPs have several contraindications and side effects. They also had strong reservations against OTC provision of ECPs by pharmacists and community health workers (CHWs) and negative attitudes toward ECP users, which serve as serious medical barriers to mainstreaming use of ECPs. Conclusion: Physicians and their professional associations exert a strong influence on the operationalization of national contraceptive policies. Evidence-based advocacy and educational campaigns targeting doctors are needed to address and resolve their reservations about ECPs, particularly about its provision as an OTC product and its distribution by CHWs. Partnerships with medical associations can help reduce doctors' negative attitudes and create a conducive environment for influencing clinical practices. Such changes are needed to increase the availability and use of ECPs as part of a

    Primary infection with Varicella Zoster virus (VZV) leads to Varicella or chickenpox. The epidemiology of Varicella has changed dramatically since the introduction of the Varicella vaccine in 1995. The routine childhood immunization in a few countries in the western world like Germany and the United States has reduced the incidence of the disease, associated complications, hospital admissions and deaths related to its complications. However, chickenpox outbreaks are common in naive unvaccinated communities in India. We report an outbreak of chickenpox that occurred in a village situated on the outskirts of Chandigarh city in North India in the winter of 2007. The outbreak was confirmed by the detection of VZV IgM by enzyme-linked immunosorbent assay (ELISA) on serum samples from the patients. In patients showing active lesions, Giemsa and indirect immunofluorescence was carried out on scrapings from vesicular lesions. A total of 162 cases occurred in the present outbreak. The serum samples were collected from 20 patients, and all of them showed positive serology for VZV IgM antibodies while 19 showed a positive VZV IgG result by ELISA. The scrapings were collected from two patients showing active lesions, and both were positive by the Tzanck smear examination, and VZV antigen could be demonstrated by immunofluorescence. There is an urgent need to identify naive communities and unvaccinated individuals at risk. Also, there is a need for regular training programmes of health workers posted in peripheral centers so that highly contagious communicable diseases can be picked up in time and such outbreaks can be prevented.

    Background & objectives: Income inequality is associated with poor health. Inequities exist in service utilization and financing for health care. Health care costs push high number of households into poverty in India. We undertook this study to ascertain inequities in health status, service utilization and out-of-pocket (OOP) health expenditures in two States in north India namely, Haryana and Punjab, and Union Territory of Chandigarh. Methods: Data from National Sample Survey 60th Round on Morbidity and Health Care were analyzed by mean consumption expenditure quintiles. Indicators were devised to document inequities in the dimensions of horizontal and vertical inequity; and redistribution of public subsidy. Concentration index (CI), and equity ratio in conjunction with concentration curve were computed to measure inequity. Results: Reporting of morbidity and hospitalization rate had a pro-rich distribution in all three States indicating poor utilization of health services by low income households. Nearly 57 and 60 per cent households from poorest income quintile in Haryana and Punjab, respectively faced catastrophic OOP hospitalization expenditure at 10 per cent threshold. Lower prevalence of catastrophic expenditure was recorded in higher income groups. Public sector also incurred high costs for hospitalization in selected three States. Medicines constituted 19 to 47 per cent of hospitalization expenditure and 59 to 86 per cent OPD expenditure borne OOP by households in public sector. Public sector hospitalizations had a pro-poor distribution in Haryana, Punjab and Chandigarh. Interpretation & conclusions: Our analysis indicates that public sector health service utilization needs to be improved. OOP health care expenditures at public sector institutions should to be curtailed to improve utilization of poorer segments of population. Greater availability of medicines in public sector and regulation of their prices provide a unique opportunity to reduce public

    Background: Nearly 14% of children worldwide do not reach their developmental potential in early childhood. The early identification of delays in achieving milestones is critical. The World Health Organization (WHO) has developed normal age ranges for the achievement of motor milestones by healthy children. This study aimed to assess the gross motor developmental achievements and associated factors among children in rural India. Materials and Methods: A cross-sectional study was conducted with rural children in North India. A pretested questionnaire was used to collect the data. The median age at the time of the highest observed milestone was calculated and compared with the WHO windows of achievement. Results: Overall, 221 children aged 4–18 months were included in the study. The median age of motor development exhibited a 0.1–2.1-month delay compared to the WHO median age of motor milestone achievement. The prevalence of the gross motor milestone achievements for each of the six milestones ranged from 91.6% to 98.4%. Developmental delay was observed in 6.3% of the children. After adjusting for different variables, children with birth order of second or more were found to be significantly associated with the timely achievement of gross motor milestones. Conclusion: The apparently healthy children of the rural area of Haryana achieved gross motor milestones with some delay with respect to the WHO windows of achievement. Although the median value of this delay was low, awareness campaigns should be implemented to promote timely identification of children with development delays. PMID:27843845

    Background & objectives: There is paucity of studies on the quality of anticoagulation in neurological patients from India. This study evaluates the quality of oral anticoagulation therapy in neurology patients. Methods: Consecutive patients attending a tertiary care neurology service in north India who were prescribed oral anticoagulant (OAC), were included. Their international normalized ratio (INR) values were prospectively monitored and the earlier INR values of the patients who were already on OAC were retrospectively analyzed. The patients with multi-organ dysfunction, pregnancy and those below 18 yr of age were excluded. The therapeutic INR range was defined as per standard recommendations. The level of anticoagulation, factors interfering with OAC and complications were noted. Results: The results were based on 77 patients with median age 40 yr. Fifty one patients received OAC for secondary stroke prevention, 23 for cerebral venous sinus thrombosis (CVST) and three for deep vein thrombosis (DVT). A total 167.9 person-years of follow up was done with a median of 1.2 (0.3-9.3) years. Of the 1287 INR reports, 505 (39.3%) reports were in the therapeutic range, 496 (38.5%) were below and 282 (21.91%) were above the therapeutic level. Stable INR was obtained in 33 (42.86%) patients only. INR level was improved by dose adjustment in 20 (26%), drug modification in two (2.6%), and dietary adjustment in six (7.8%) patients. Three patients were sensitive and five were resistant to OAC. Complications were noted in 28 instances; thromboembolic in 16 and haemorrhagic stroke in 12. The overall complication rate was 16.7 per 100 person-years. Interpretation & conclusions: It may be concluded that stable therapeutic INR is difficult to maintain in neurological patients. Optimal modification of diet, drug and dose of oral anticoagulant may help in stabilization of INR. PMID:27377498

    Background: Because of the widespread prevalence of the various cutaneous mycoses in a tropical country like India, it is important to know their patterns of etiology and clinical presentations. Aim: The present study was conducted in order to identify the clinical pattern of various cutaneous mycoses and the common etiological agents affecting the study populations admitted in SMS Hospital, Jaipur, in North India. Materials and Methods: Skin scrapings and hair and nail samples of 160 patients with clinical suspicion of dermatophytosis were collected and subjected to direct microscopy and were cultured in Sabouraud's dextrose agar. Fungal species were identified by macroscopic and microscopic examination. Data were presented as simple descriptive statistics (SPSS, Version 17.0 (Chicago Il, USA). Epi Info Version 3.5.1 (CDC, Atlanta, Georgia, USA). Results: Among the 160 clinically suspected patients of cutaneous mycoses, 60 (37.5%) were confirmed by culture. Dermatophytes and non-dermatophytes (NDM) were isolated from 66.6% (40/60) and 33.3% (20/60) of the positive cultures, respectively. Tinea capitis (50%) 30/60 was the most frequent clinical pattern and genus Trichophyton violaceum 32.5% (13/40) was the most common isolate in dermatophytosis-positive samples. Among the patients positive for NDM by culture, Tinea unguium 35% (7/20) was the most common clinical presentation and Aspergillus species 40% (8/20) were the most common etiological agents isolated. Conclusion: Although dermatophtes have been isolated from the cases of cutaneous mycoses all over the world with various frequencies, the role of NDM in the different cutaneous infections other than those of nail infections need to be evaluated.

    Anti-glomerular basement (anti-GBM) disease is an uncommon disorder with a bimodal age of presentation. Patients presenting with dialysis-dependent renal failure have poor renal outcomes. There is limited data regarding the clinical presentation and outcomes of anti-GBM disease from India. We conducted this prospective study to analyze the clinical presentation and outcomes of anti-GBM disease at a large tertiary care hospital in North India over 1½ years. Subjects with a biopsy proven anti-GBM disease (light microscopic examination showing crescents and immunofluorescence examination showing linear deposition of IgG) with or without positive anti-GBM antibodies in serum were included in the study and followed-up for at least 12 months. All the patients were treated with steroids, cyclophosphamide, and plasma exchange. A total of 17 patients (nine males) were included. The mean age at presentation was 39.11 ± 16.58 (range 11-72) years. Twelve patients (70%) presented with rapidly progressive glomerulonephritis (RPGN), 4 (23.5%) presented with Goodpasture syndrome, while 1 (5.8%) had nephritic syndrome, 7 (41%) were hypertensive, and 14 (82.3%) required dialysis at the time of presentation. Four patients (23.5%) had associated anti-neutrophil cytoplasmic antibody positivity (anti-myeloperoxidase antibodies in all). Fourteen (87.5%) patients had crescentic glomerulonephritis, while 5 (31.25%) showed necrotizing (n = 4) or granulomatous (n = 1) in the vasculitis. Of 16 patients who received treatment, four (23.25%) achieved complete remission. In this single-center study, the majority of anti-GBM disease patients presented with RPGN and had crescentic glomerulonephritis on biopsy with poor treatment outcome.

    Hepatitis viral infection is a leading cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). Over one million people are estimated to be persistently infected with hepatitis C virus (HCV) worldwide. As capsid core protein is the key element in spreading HCV; hence, it is considered to be the superlative target of antiviral compounds. Novel drug inhibitors of HCV are in need to complement or replace the current treatments such as pegylated interferon’s and ribavirin as they are partially booming and beset with various side effects. Our study was conducted to predict 3D structure of capsid core protein of HCV from northern part of India. Core, the capsid protein of HCV, handles the assembly and packaging of HCV RNA genome and is the least variable of all the ten HCV proteins among the six HCV genotypes. Therefore, we screened four phytochemicals inhibitors that are known to disrupt the interactions of core and other HCV proteins such as (a) epigallocatechin gallate (EGCG), (b) ladanein, (c) naringenin, and (d) silybin extracted from medicinal plants; targeted against active site of residues of HCV-genotype 3 (G3) (Q68867) and its subtypes 3b (Q68861) and 3g (Q68865) from north India. To study the inhibitory activity of the recruited flavonoids, we conducted a quantitative structure–activity relationship (QSAR). Furthermore, docking interaction suggests that EGCG showed a maximum number of hydrogen bond (H-bond) interactions with all the three modeled capsid proteins with high interaction energy followed by naringenin and silybin. Thus, our results strongly correlate the inhibitory activity of the selected bioflavonoid. Finally, the dynamic predicted capsid protein molecule of HCV virion provides a general avenue to target structure-based antiviral compounds that support the hypothesis that the screened inhibitors for viral capsid might constitute new class of potent agents but further confirmation is necessary using in vitro and in vivo

    Migrant workers are designated a bridge population in the spread of HIV and therefore if infected, should be diagnosed and treated early. This study examined pathways to HIV diagnosis and access to care for rural-to-urban circular migrant workers and partners of migrants in northern India, identifying structural, social and individual level factors that shaped their journeys into care. We conducted a qualitative study using in-depth interviews with HIV-positive men (n = 20) and women (n = 13) with a history of circular migration, recruited from an antiretroviral therapy centre in one district of Uttar Pradesh, north India. Migrants and partners of migrants faced a complex series of obstacles to accessing HIV testing and care. Employment insecurity, lack of entitlement to sick pay or subsidised healthcare at destination and the household's economic reliance on their migration-based livelihood led many men to continue working until they became incapacitated by HIV-related morbidity. During periods of deteriorating health they often exhausted their savings on private treatments focused on symptom management, and sought HIV testing and treatment at a public hospital only following a medical or financial emergency. Wives of migrants had generally been diagnosed following their husbands' diagnosis or death, with access to testing and treatment mediated via family members. For some, a delay in disclosure of husband's HIV status led to delays in their own testing. Diagnosing and treating HIV infection early is important in slowing down the spread of the epidemic and targeting those at greatest risk should be a priority. However, despite targeted campaigns, circumstances associated with migration may prevent migrant workers and their partners from accessing testing and treatment until they become sick. The insecurity of migrant work, the dominance of private healthcare and gender differences in health-seeking behaviour delay early diagnosis and treatment initiation.

    The nervous system is among the most frequent and serious targets of human immunodeficiency virus (HIV) infection. The infection usually occurs in patients with profound immunosuppression. In 10 - 20% of the patients, the presence of a neurological disease is the first manifestation of symptomatic HIV infection. Despite the wide prevalence of neurological manifestations in HIV, there is no study examining the clinical manifestations of this disease in the resource- limited communities from north-eastern parts of India. To characterize the neurological involvement in patients with HIV infection at a tertiary care institute in northeast India, we studied various neurological presentations of HIV. This was a retrospective observational study done at a tertiary care institute in northeast India over a period of 6 years from August 2008 to September 2014. A total of 91 HIV seropositive patients of both genders, aged >18 years, showing clinical evidence of central nervous system (CNS) involvement, and admitted in a tertiary care institute were included. Their clinical manifestations, laboratory investigations, and imaging were studied. Tuberculous meningitis was the most common presentation as secondary CNS illness (43.9%), followed by cryptococcal meningitis (14.2%) and cerebrovascular accidents (5.49%). Furthermore, 6.59% had neurosyphilis, 6.59% had acquired immune deficiency syndrome (AIDS) - associated dementia, and peripheral neuropathy occurred in 16.4% of the patients. Headache was the most common neurological symptom seen in 25% of the patients. Seizures were noted in 25% of the pateints. CD4 was significantly low in most of the patients with progressive multifocal leukoencephalopathy, HIV associated encephalopathy (HAD) and cryptococcal meningitis compared with other neurological manifestations. CD4 counts in tuberculous meningitis and HAD were 110.3/μl and 95/μl, respectively. CNS tuberculosis was the most common secondary infection seen in HIV patients

    Over the last half century, the green revolution has transformed India from a famine-prone, drought-susceptible country, into the world's third largest grain producer and one of the most intensely irrigated regions on the planet. This is in no small part due to the country's vast water resources along with an increase in tubewells and more advanced abstraction methods. While agricultural intensification has had undeniable benefits, it has, and continues to have a significant impact on water resources. Unless solutions which take into consideration the ever evolving socio-economic, hydrological and climatic conditions are found, India's agricultural future looks bleak.This research examines the irrigation behaviour of farmers, using data collected during field work in the State of Uttar Pradesh within the Ganges Basin of North India. Significant differences in farmer behaviour and irrigation practices are highlighted, not only between State districts but between individual farmers. This includes the volume of irrigation water applied and the price paid, as well as differences in the yields of crops produced. Analyses of results suggest that this is due to a number of factors, particularly the source of irrigation water. Study areas which had access to cheaper, but crucially less reliable, canal water were found to invest in more efficient water saving technologies in order to reduce the overall cost of irrigation during periods where less expensive canal water is not available. As a result, overall water use and irrigation cost is lower and yields are higher despite very similar climatic conditions. While cheap canal water is not an option for all farmers, the results show that the introduction of more efficient water saving technologies, despite the significant capital expenditure is a viable option for many farmers and costs can be recovered in a relatively short space of time. In addition, the reduction of declining water levels mean that water is abstracted from

    The present study is an attempt to examine possible associations between ABO blood groups and the risk of osteoporosis among postmenopausal women of North India. This cross-sectional study involved 250 postmenopausal women from North India, ranging in age from 45 to 80 years. Four anthropometric measurements (height, weight, waist circumference and hip circumference), blood sample (ABO status and haemoglobin concentration) and grip strength (dominant as well as non-dominant hand) of all the participants were taken. Bone mineral density (BMD) was evaluated by using dual energy X-ray absorptiometry (DXA) at lumbar spine (L1-L4) and proximal femur. Analysis of data revealed that at lumbar spine (L1-L4) osteoporosis was more prevalent among individuals with blood group A (31.58%), followed by those with blood group B (29.67%), AB (28.57%) and then blood group O (15%), whereas for proximal femur individuals with blood group AB (21.43%) showed the highest prevalence of osteoporosis followed by a decreasing trend from blood group A (17.54%) to B (12.08%) and then O (5%). Total prevalence of osteoporosis was 26.4% in lumbar spine and 13.2% in proximal femur, indicating that lumbar spine had an elevated risk for osteoporosis among postmenopausal women. All the anthropometric variables, haemoglobin concentration as well as grip strength of individuals with blood group O demonstrated non-significant differences with non-O blood group except for weight and body mass index, where differences were statistically significant. Women with blood group O exhibited significantly higher bone mineral density for lumbar spine (0.90 g/cm(2) vs. 0.85 g/cm(2), p<0.05) and proximal femur (0.87 g/cm(2) vs. 0.79 g/cm(2), p<0.05) as compared to those with non-O blood group, thereby suggesting an increasing risk of osteoporosis among individuals with non-O blood group.

    Background: Due to wider access to and free antiretroviral therapy (ART) program, the number of children dying due to acquired immune deficiency syndrome (AIDS)-related causes has declined and the nature and duration of human immunodeficiency virus (HIV)/AIDS caregiving has also dramatically altered. The care of children living with HIV/AIDS (CLHA) places a significant additional burden on the caregivers. Aims: This study was conducted to assess the perceived burden among caregivers of children living with HIV in North India. Materials and Methods: A hospital-based cross-sectional study among 156 CLHA-caregiver dyads in North India was conducted from June 2010 to May 2011. Data were collected by using a pretested structured interview schedule. The caregiver burden was measured with a 36-item scale adapted from Burden Assessment Schedule of Schizophrenia Research Foundation (BASS). Child characteristics, caregiver characteristics, caregiving burden, the knowledge of caregivers, and issues related to health care, nutrition, education, and psychological aspects were studied. Results: Caregivers had a mean age of 35.9 ± 10.2 years. Women accounted for over three-fourth (76.9%) of the caregivers. Nearly two-third of them (65.4%) reported as living with HIV. The mean caregiver burden score was 68.7 ± 2.9. A majority of the caregivers reported either low or moderate burden. Standardized percentage score was high in the domains of physical and mental health, external support, patients’ behavior, and caregivers’ strategy and seemed to be comparatively less in the other domains such as support of the patient and taking responsibility. Conclusions: Caring of children is a universal practice but there is a need of special care for children living with HIV. The majority of caregivers who were usually the mothers perceived the burden and need to be assisted in caring for the child. Stigma and discrimination with HIV infection further increased the burden as caregivers did

    This study analysed buffaloes from north-east India and compared their nuclear and mitochondrial DNA variations with buffaloes of mainland India, China, Mediterranean and South-East Asia. Microsatellite genotypes of 338 buffaloes including 210 from six north-east Indian buffalo populations and three mainland Indian breeds were analysed to evaluate their genetic structure and evolutionary relationships. Phylogenetic analysis and multidimensional scaling plot of pairwise FST revealed the clustering of all swamp-type buffaloes of north-east India with Lower Assamese (significantly hybrid type) buffaloes in one plane and all the mainland river buffaloes in another plane while the upper Assamese buffaloes being distinct from both these clusters. Analysis of mtDNA D-loop region of 530-bp length was performed on 345 sequences belonging to 23 buffalo populations from various geographical regions to establish the phylogeography of Indian water buffalo. The swamp buffaloes of north-east India clustered with both the lineages of Chinese swamp buffalo. Multidimensional scaling display of pairwise FST derived from mitochondrial DNA data showed clustering of upper Assamese, Chilika and Mediterranean buffaloes distinctly from all the other Indian buffalo populations. Median-joining network analysis further confirmed the distinctness and ancestral nature of these buffaloes. The study revealed north-east region of India forming part of the wider hybrid zone of water buffalo that may probably extend from north-east India to South-East Asia. © 2015 Blackwell Verlag GmbH.

    The great 1934 Himalayan earthquake of moment magnitude (Mw) 8.1 generated a large zone of ground failure and liquefaction in north Bihar, India, in addition to the earthquakes of 1833 (Mw ~7.7) and 1988 (Mw 6.7) that have also impacted this region. Here, we present the results of paleoliquefaction investigations from four sites in the plains of north Bihar and one in eastern Uttar Pradesh. The liquefaction features generated by successive earthquakes were dated at AD 829-971, 886-1090, 907-1181, 1130-1376, 1112-1572, 1492-1672, 1733-1839, and 1814-1854. One of the liquefaction events dated at AD 829-971, 886-1090, and 907-1181 may correlate with the great earthquake of AD ~1100, recognized in an earlier study from the sections across the frontal thrust in central eastern Nepal. Two late medieval liquefaction episodes of AD 1130-1376 and 1492-1672 were also exposed in our sites. The sedimentary sections also revealed sandblows that can be attributed to the 1833 earthquake, a lesser magnitude event compared to the 1934. Liquefactions triggered by the 1934 and 1988 earthquakes were evident within the topmost level in some sections. The available data lead us to conjecture that a series of temporally close spaced earthquakes of both strong and large types, not including the infrequent great earthquakes like the 1934, have affected the Bihar Plains during the last 1500 years with a combined recurrence interval of 124 ± 63 years.

    There is a rapid emergence of cardiovascular disease in India with economic development, leading to an increase in mortality due to these diseases. The exact causes of death in India, however, are not known. We studied randomly selected death records from 2222 (1385 men and 837 women) victims, aged 25-64 years, out of 3034 death records during 1999-2001 at the Municipal Corporation, Moradabad. All the families of these victims could be contacted individually to find out the causes of death, by scientists/doctors-administered pre-tested verbal autopsy questionnaires, completed with the help of spouses and local treating doctors practising in the concerned lane. Social classes were assessed by a questionnaire based on attributes of per capita income, occupation, education, housing and ownership of consumer luxury items in the household. Causes of mortality included infectious diseases (41.1%, n = 915) such as tuberculosis, pneumonia, chronic obstructive pulmonary disease, diarrhea/dysentery, hepatitis B, and inflammatory brain infections as the commonest causes of death in the urban population of North India. The second most common causes of death were circulatory diseases (29.1%, n = 646), including heart attacks (10.0%), strokes (7.8%), valvular heart disease (7.2%, n = 160), sudden cardiac death, and inflammatory cardiac disease (each 2.0%, n = 44). Malignant neoplasm (5.8%, n = 131), injury (14.0%, n = 313), including accidents, fire and falls, and poisonings were also quite common causes of death. Miscellaneous causes of death were noted in 9.1% (n = 202) death records, including diabetes mellitus (2.2%, n = 49), suicides (1.8%, n = 41), congenital anomalies (1.0, n = 37), dental caries infections (1.9, n = 42), and burns (1.3%, n = 33). Pregnancy and perinatal causes (0.72%, n = 15) were not commonly recorded in our study. Circulatory diseases as the cause of mortality were statistically significantly more common among higher social classes (1-3) than in lower

    Human hair is frequently used as a bioindicator of mercury exposure. Mercury (Hg) has for centuries been a useful metal in a variety of applications. Unfortunately, this usefulness is counterbalanced by its neurotoxicological health impact. The US Environmental Protection Agency recommends keeping the hair Hg level <1.0 µg/g. Therefore, an investigation has been performed in order to ascertain the hair Hg levels among the people living at the terai belt of North India. Hair samples were collected from 111 individuals and were placed in an identified plastic bag, stapled to prevent the shift of the hair strand. Samples were analyzed by combustion, gold amalgamation, atomic absorption spectrometry (C-GA-AAS). The mean Hg level in hair was 0.28 µg/g for the whole group ranging from 0.0012 to 1.9091 µg/g. The mean hair Hg levels were 0.16 µg/g for men and 0.12 µg/g for women, indicating that men had higher hair Hg levels than women. Total hair Hg was found to be significantly associated with age, gender and fish consumption frequency. 98 % of the total sample had hair Hg concentrations less than 1.0 µg/g, i.e, within safe dose, whereas only 2 % had Hg concentrations greater than 1.0 µg/g, thereby exceeding the safe dose.

  11. Only when the boat has started sinking: a maternal death in rural north India.

    This paper uses a close reading of villagers' responses to the death in childbirth of a Muslim woman to raise questions about India's current policy emphasis on institutional delivery as a means of reducing maternal mortality. After introducing the context and methods of our research, we describe recent policy interventions related to maternal health, including the National Rural Health Mission established in 2005. We then outline villagers' commentaries on the specific maternal death, focusing on the costs to women's health (and sometimes life) of high fertility; the lack of care available from rural government facilities and staff and the preference for delivering at home with the aid of local practitioners; the financial constraints that make people hesitate to seek medical treatment; and the high costs of private treatment and the poor treatment experienced in government facilities. Our core argument is that government health care provision in rural Uttar Pradesh is embedded in a moral universe characterised by widespread and long-term mistrust of state services and that encouraging institutional deliveries without addressing the perceptions of potential service users is a seriously flawed approach to reducing maternal mortality. The paper draws primarily on ethnographic research funded by the Wellcome Trust during 2002-2005, in a Muslim village in rural Bijnor district (in north-western Uttar Pradesh).

    Indigenous strains of Trichoderma species isolated from rhizosphere soils of Tea gardens of Assam, north eastern state of India were assessed for in vitro antagonism against two important tea fungal pathogens namely Pestalotia theae and Fusarium solani. A potent antagonist against both tea pathogenic fungi, designated as SDRLIN1, was selected and identified as Trichoderma viride. The strain also showed substantial antifungal activity against five standard phytopathogenic fungi. Culture filtrate collected from stationary growth phase of the antagonist demonstrated a significantly higher degree of inhibitory activity against all the test fungi, demonstrating the presence of an optimal blend of extracellular antifungal metabolites. Moreover, quantitative enzyme assay of exponential and stationary culture filtrates revealed that the activity of cellulase, β-1,3-glucanase, pectinase, and amylase was highest in the exponential phase, whereas the activity of proteases and chitinase was noted highest in the stationary phase. Morphological changes such as hyphal swelling and distortion were also observed in the fungal pathogen grown on potato dextrose agar containing stationary phase culture filtrate. Moreover, the antifungal activity of the filtrate was significantly reduced but not entirely after heat or proteinase K treatment, demonstrating substantial role of certain unknown thermostable antifungal compound(s) in the inhibitory activity.

    This study was performed to provide information on the frequencies of Rh antigens, alleles, phenotypes, and haplotypes from our region in India and to compare them with those from other races. This observational study was conducted on blood donors from March 2009 to August 2011 using a fully automated system for Rh typing of blood cells. The data were collected and calculations done to determine the antigen, phenotypes, allele and haplotype frequencies. The chi square test was used for comparisons between the results of our study and those of other studies. A total of 51,857 donors were included in this study. The most common Rh antigen found was "e". DCCee was the most prevalent phenotype in our study with the phenotype distribution being significantly different between our study and other studies from different regions of the world. We have determined the prevalence of Rh antigens and Rh phenotypes in the North Indian blood donor population and derived the allele and haplotype frequencies in the same population. The Rh blood group distribution in this population was different from that in other populations.

    Background. The pattern of skin morbidity in an area depends on climate, geography, socioeconomic status, nutrition, genetics, and habits of the community. Objective. The objective of the present study was to describe the morbidity profile of patients attending dermatology outpatient department in a tertiary care centre of Garhwal hills, North India. Methodology. This is a record based study carried out using the morbidity registers. Patient details, diagnosis, and treatment provided by physicians were documented in the morbidity register. ICD coding was done to categorize the patients. Results. The total number of new episodes of illnesses treated in the skin outpatient department during 2009–2014 was 47465. Adults (>18 years) constituted about 80.9%. Among adults, about 59.9% were males. Overall the infections of the skin and subcutaneous tissue were the most common (32.6%) followed by the disorders of skin appendages (19.8%), and dermatitis and eczema (18.8%). Of the total patients 16.9% were affected by dermatitis and 16.7% by acne. Psoriasis, urticaria, melasma, and vitiligo were present in 3.4%, 3.4%, 3.6%, and 3.3% patients, respectively. Conclusion. This knowledge will help in planning appropriate range services to meet the patients' needs and help in training of health staff to meet these needs. PMID:27738425

    Sushina nepheline syenite gneisses of Early Proterozoic North Singhbhum Mobile Belt (NSMB), eastern India suffered regional metamorphism under greenschist-amphibolite transitional facies condition. The Agpaitic Sushina nepheline syenite gneisses consist of albite, K-feldspar, nepheline (close to Morozewicz-Buerger composition), aegirine, biotite, epidote, piemontite, sodalite, cancrinite, natrolite and local alkali amphibole. Accessory phases include zircon, hematite, magnetite, rare pyrochlore and occasional eudialyte and manganoan calcic zirconosilicates. Mineral chemistry of albite, K-feldspar, nepheline, aegirine, alkali amphibole, natrolite and zirconium silicate minerals are described. The detailed textural features together with chemical data of some minerals indicate metamorphic overprint of these rocks. A new reaction is given for the genesis of metamorphic epidote. Metamorphic piemontite suggests greenschist facies metamorphism under high fO2 (Hematite-Magnetite buffer). Up to 15.34 mol% of jadeite component in aegirine suggests that the metamorphic grade of the nepheline syenite gneiss reached at least to greenschist-amphibolite transitional facies or higher. Nepheline geothermometry suggests temperature of metamorphism <500 °C, which is consistent with greenschist facies metamorphism of surrounding chlorite-biotite-garnet phyllite country rock.

    An efficient in vitro regeneration protocol has been developed from shoot tips of Drosera burmannii Vahl., a carnivorous plant of north-east India. Various plant growth regulators were used to study their efficacy in the induction of multiple shoots and roots. Of the various treatments, the maximum number of shoots (28.8 ± 1.5) and roots (9.7 ± 0.6) was observed in one-fourth strength standard medium (MS with 50 mg/l citric acid and 10 mg/l ascorbic acid) supplemented with 4 mg/l 6-benzylaminopurine (BAP) and 4 mg/l α-naphthalene acetic acid (NAA) followed by 26.8 ± 1.4 shoots in one-fourth strength SM fortified with 4 mg/l kinetin (KN) and 4 mg/l NAA. The well-developed plantlets with shoots and roots were potted in small plastic glasses filled with a mixture of sand and farmyard manure (3:1); these plantlets when transferred to a glasshouse for hardening and acclimatization showed 90% survival.

    Purpose: To evaluate the epidemiological characteristics and outcomes of ocular injuries resulting from the use of firecrackers during the Diwali festival in all age groups. Materials and Methods: A single-center, retrospective, hospital-based case series presenting with ocular trauma consequent to fireworks usage in a tertiary eye care center in North India during the 5 days of Diwali festival from 2011 to 2015 was conducted. Results: A total of 53 eyes of 45 patients were included in the study, out of which the vast majority (39/87%) were males. The mean age was 20.55 years. Almost an equal number of bystanders (25/55.5%) were affected as compared to people handling the fireworks (20/44.44%). Five (9.43%) eyes had open-globe injury, whereas 48 (90.56%) eyes had closed-globe injury. Eighteen (33.96%) eyes underwent surgical intervention. Thirty-three (62.26%) eyes had final vision >20/200 with eight (15.09%) eyes being vision <3/60 in the affected eye. Conclusion: Firework-related ocular trauma can lead to serious visual impairment. Mandatory legislative laws pertaining to the manufacture, sale, and use of fireworks and creating public awareness can reduce the incidence of this preventable cause of blindness in the society. Initiating new policies for retailers involved in sale of these firecrackers can also bring in decrease of such morbidities. PMID:28345570

    ALK gene rearrangement in the lung adenocarcinomas is the second most common (1.6-11.7% of NSCLC) targetable genomic change after EGFR mutations. However, the prevalence and clinicopathological features of ALK-rearranged lung adenocarcinomas from North India are lacking. A total of 240 cases of lung adenocarcinoma were screened for EGFR mutations and for ALK expression. Smoking status, TNM stage, and treatment response were recorded in all cases. Out of 240 cases screened, 37 cases were positive for EGFR mutations and 17 cases (7.08%) showed ALK positivity with immunohistochemistry and break-apart FISH. On excluding 37 EGFR mutation-positive cases, the incidence of ALK-positive adenocarcinoma appears to be higher (17/203 cases, 8.03%). Eight were men and nine were women with mean age of 51.7 years. Majority (62.5%) were non-smokers and had unresectable disease (70.6% stage IV, 17.6% IIIB). The morphological patterns noted were solid (12 cases), papillary (four cases), and micropapillary (one case). Signet ring (two cases) and clear cell change (one cases) were noted. Out of five patients who received crizotinib, three had partial response and two had stable disease. ALK-rearranged lung adenocarcinomas account for a minor proportion of NSCLC with prevalence similar to that reported in literature. However, as contrast to published data in our series, patients were in older age group and had solid and papillary pattern on morphology with an aggressive course.

    Background. Classically, each kidney is supplied by a single renal artery originating from abdominal aorta. The present study aimed at its variations and their embryological and clinical correlation. Material and Methods. The formalin-fixed thirty-seven cadavers from north India constituted the material for the study. During routine abdominal dissection conducted for medical undergraduates at the department of anatomy, the kidneys along with their arteries were explored and the morphological variations of renal arteries were noted. Results. We observed supernumerary renal arteries in 23/37 (62.2%) cases (48.6% of aortic origin and 13.5% of renal origin) on the right side and 21/37 (56.8%) cases (45.9% of aortic origin and 10.8% of renal origin) on the left side. Supernumerary renal arteries entered the kidney through hilum, superior pole, and inferior pole. Conclusion. Awareness of variations of renal artery is necessary for surgical management during renal transplantation, repair of abdominal aorta aneurysm, and urological procedures and for angiographic interventions.

  20. A tangled weave: Tracing outcomes of education in rural women's lives in North India

    This paper is based on the findings of a research study which traced 56 rural women learners 15 years after they had participated in an empowerment and education programme in North India. It attempts to understand, from the perspectives of women from marginalised communities, the ways in which participating in the programme had been empowering for them, or not. While most of the women were indeed able to transform several areas in their lives, this study illustrates that empowering outcomes cannot be assumed or articulated in categorical terms and that bringing about change requires the negotiation of power at various levels. The women's narratives stand in contrast to the prevalent discourses around women's literacy and empowerment, which highlight the importance of literacy only in terms of its positive impact on attaining development goals. Despite the vigorously discussed de-politicisation of the concept of empowerment, the authors show in this paper that empowerment, when informed by a critical feminist understanding, continues to provide a useful framework to analyse women's experiences related to education, as a process enabling women to understand and negotiate structures of power - which are neither static nor wholly dominating - and to find spaces to exercise agency. There are few longitudinal studies which trace the long-term impact of educational programmes on adult women, and most studies are in the nature of impact assessments of programmes. Through this paper the authors argue for the need to analyse the complexities around the relationship between women's education and empowerment.

    Background: There are significant gaps in the scientific literature concerning female sexual behavior and attitudes surrounding sexuality, which have definitive implications on public health and clinical work. Aim: To study the sexual behavior of young married Indian women. Materials and Methods: The study group comprised 100 consecutive women attending the Department of Pediatrics for the care of noncritical children in a multispecialty, tertiary care teaching hospital setting in North India. Current levels of sexual functioning and satisfaction were assessed by using the Brief Index of Sexual Functioning for Women (BISF-W). All participants were also administered a translated and culturally adapted instrument called Sex Knowledge and Attitude Questionnaire-II (SKAQ-II). Results: Peno-vaginal sex continues to be considered the most desired and actually performed sexual activity for arousal and orgasm, followed by kissing and foreplay. Difficulties while performing sexual activity, in the form of physical problems, were faced by 17% of the participants. The participants displayed adequate sexual knowledge and favorable attitude towards sexuality as measured by SKAQ-II. Conclusion: The present study is a preliminary effort to understand the contemporary female sexual behavior, knowledge and attitude by employing standard instruments. Still further studies are required in this area. PMID:19876477

    In 1988, India's population stood at 817 million, 25% of which was concentrated in urban areas. The annual rate of population growth is 2.01%. Life expectancy is currently 56 years, and infant mortality is 90/1000 live births. Education is compulsory to the age of 14 years, but the adult literacy rate is only 36%. Of the work force of 300 million, 70% are engaged in agriculture, 19% are in industry and commerce, 8% work in the services and government sector, and 3% are employed in transport and communications. India's gross national product currently stands at US$246 billion, with a real growth rate of 1.8% and a per capita income of $313. Although India is a federal republic, its central government has greater power in relation to its states than is the case in the US and there is a parliamentary system. Nonetheless, some states have been revitalizing traditional village councils and introducing grassroots democracy at the village level. A relatively sophisticated industrial base and pool of skilled labor have emerged since India achieved independence, although agriculture remains the crucial economic sector. There was a surge in agricultural production in the late 1960s and early 1970s as a result of the "green revolution" that made India largely self-sufficient in grain production through the use of hybrid seeds, irrigation, and fertilizer. However, failed monsoons and severe drought conditions have created fluctuations in the output of the agricultural sector in recent years. Gradual deregulation of industry and trade is providing increased incentives for foreign trade, and the Indian Government is encouraging collaborations that involve the transfer of high technology.

    Background & objectives: Inhalants are substances whose chemical vapors are inhaled to produce euphoric, disinhibiting, and exciting effects. Data on inhalant abuse in India are relatively scarce. We report the demographic and clinical profile of inhalant users among the treatment seekers at a Drug De-addiction and Treatment Centre in north India. Methods: The records of treatment seekers at the Drug De-addiction and Treatment Centre, over 10 years (2002-2011) were scanned to identify 92 cases reporting inhalant use. Of these 92 cases, the complete record files were available for 87 (94.6%) cases. These case files were reviewed and the relevant data were collected and analyzed. Results: Over the study period of 10 years, the number of cases with inhalant abuse per year rose steadily to peak at 20 cases (4.08% of new cases) in 2006 and then stabilized at 1-3 per cent of new cases annually. Of the 87 cases studied, all were males with a mean age of 18.9±4.12 yr, mean education of 9.8±3.42 yr and mean family income of 7676±7343.15 (median: 5000). Majority of subjects were unmarried (89.7%), urban resident (79.3%), and from a nuclear family (78.2%). About half of the subjects were students (50.6%). The most common inhalant used was typewriter correction fluid (73.6%) followed by typewriter diluent fluid (19.5%) and glue (6.9%). The most common reason for initiation was curiosity. The mean age of onset of inhalant use was 16.3±4.22 yr. Most subjects fulfilled the criteria for inhalant dependence (85.1%). Psychiatric co-morbidity and the family history of substance dependence were present in 26.4 and 32.9 per cent subjects, respectively. Majority of the subjects reported drug related problems, occupation and finance being the worst affected. Interpretations & conclusions: Our results showed that the inhalant users were mostly urban youth belonging to middle socio-economic class families.

    Recent studies have documented that a certain type of organic carbon (predominantly water soluble) significantly absorb light at near-UV (300-400) and visible regions, and termed as "Brown Carbon (BrC)". Recent global models estimate that light absorption by BrC in different regions of the world may be 30-70% of that due to black carbon (BC). To assess the role of BrC on regional and global level, it is important to understand their sources and characteristics on temporal and spatial scale, which is severely lacking in literature. The major focus of present study is to fill this gap over India. The study site, Kanpur (26.5°N, 80.3°E, 142 m amsl) located in North India, receives emissions majorly from industries, vehicles, biofuel and biomass burning. Semi-continuous measurements of water soluble organic carbon (WSOC), BrC, BC and chemical composition of organic and inorganic aerosols were performed during winter season (December, 2015-Dec to February, 2016) using state-of-the-art instruments. Diurnal variability in the absorption coefficient of BrC at 365 nm (babs_365) showed higher values during late evening through early morning and attributed to primary emissions from biomass burning (BB) and fossil fuel burning (FFB). The babs_365 reduces as day progresses, which is ascribed to photo bleaching/dissociation of BrC. Primary BrC, assessed based on H:C ratios from HR-ToF-AMS, dominates the total BrC abundance with higher babs_365. Secondary BrC, assessed based on O:C ratios, was abundant in the morning and afternoon with lower babs_365. Further, diurnal variability in ratios of babs_365 with babs_405 and babs_420 suggests that BrC composition is not uniform throughout the day. Using BC370/BC880 ratio as an indicator of BB vis-à-vis FFB derived component, BB derived BrC was found to be more absorbing than that derived from FFB. Fog processing of BrC was also found to be affecting babs_365 positively. Detailed results will be presented.

    This cross-sectional survey was conducted in two randomly selected villages in Moradabad in North India to demonstrate the association of magnesium status with hypertension in relation to socioeconomic status (SES) in a rural population. There were 1769 subjects (894 males, 875 females) between 25 and 64 years of age, randomly selected and divided into social classes 1-4 depending upon various sociological attributes. The survey methods were a validated questionnaire, blood pressure measurements by mercury manometer, and blood analysis for serum magnesium. Social class 1 and 2 were associated with a greater prevalence of hypertension. The overall prevalence of hypertension diagnosed by JNC-V criteria (> 140/90 mm Hg) was 17.7 per cent (n = 313) and the prevalence was comparable in both sexes and increased with age. Among social class 1 and 2 subjects, there was a higher prevalence of obesity and sedentary lifestyle, a lower intake of dietary magnesium, and a lower serum magnesium compared to social class 3. Logistic regression analysis with adjustment for age showed that SES has a positive relation with hypertension (odds ratio 1.08 men, 1.07 women, P < 0.05), body mass index (odds ratio 1.14 men, 1.13 women, P < 0.01), and sedentary lifestyle (odds ratio 1.38 men, 1.32 women, P < 0.05) in both sexes, and with salt intake in women (odds ratio 1.28, P < 0.05). The odds ratio indicated that a higher intake of magnesium (odds ratio 1.14 men, 1.17 women, P < 0.05) and a higher serum magnesium (odds ratio 1.12 men, 1.15 women, P < 0.05) were associated with a lower risk of hypertension. The findings suggest that social class 1 and 2 subjects in some rural populations of India have a higher prevalence of hypertension and dietary intake of magnesium, and serum magnesium levels were inversely associated with the risk of hypertension.

    Social exclusion is both cause and consequence of mental disorders. People with mental disorders (PWMD) are among the most socially excluded in all societies yet little is known about their experiences in North India. This qualitative study aims to describe experiences of exclusion and inclusion of PWMD in two rural communities in Uttar Pradesh, India. In-depth interviews with 20 PWMD and eight caregivers were carried out in May 2013. Interviews probed experiences of help-seeking, stigma, discrimination, exclusion, participation, agency and inclusion in their households and communities. Qualitative content analysis was used to generate codes, categories and finally 12 key themes. A continuum of exclusion was the dominant experience for participants, ranging from nuanced distancing, negative judgements and social isolation, and self-stigma to overt acts of exclusion such as ridicule, disinheritance and physical violence. Mixed in with this however, some participants described a sense of belonging, opportunity for participation and support from both family and community members. These findings underline the urgent need for initiatives that increase mental health literacy, access to services and social inclusion of PWMD in North India, and highlight the possibilities of using human rights frameworks in situations of physical and economic violence. The findings also highlight the urgent need to reduce stigma and take actions in policy and at all levels in society to increase inclusion of people with mental distress and disorders.

  9. Crop Burning in the North and Northwestern Parts in India and Its Impact on Air Quality and Aerosol Parameters

    2015-12-01

    Crop burning in the North and Northwestern parts of India started sometime in 1986 when the farmers started using mechanized forming. During October-November and April-May crop residues are burnt which is a serious health threat to people living in the areas and also it impacts climate of the northern parts of India including Himalayan region. Detailed analysis of satellite data, MODIS, AIRS and OMI AURA have been carried out to study aerosol and meteorological parameters near the source of biomass burning and also at far region. During crop burning period, pronounced changes in the aerosol and meteorological parameters are observed at different pressure levels. The emissions from the crop burning are spread in the Indo-Gangetic plains from west-east, over the Himalayan region and over the central parts of India depending upon the wind direction and wind speed. The air quality changes anomalously affecting the visibility and aerosol parameters. The emissions from crop burning mixes with the local emissions (vehicular and industrial sources) affecting the trace gas concentrations and aerosol optical parameters as a result dense haze fog and smog are observed during burning period. Long range transport of emissions from crop burning over India and its various climatic and health consequences will be presented.

    The present work is aimed at the geochronological investigations of the minerals of some granitic rocks and estimation of uranium contents in minerals, rocks and water of some parts of the North-East India with the help of fission track (FT) technique. The study includes FT dating of minerals from granites of four different plutons and from pegmatites of two different regions of Meghalaya, annealing studies of the minerals including the correction of the observed mineral ages and calculation of the cooling and uplift rates of the rocks. Precision on the errors of the mineral ages has also been studied in detail in the present work. The experiment was carried out at the Research laboratories of the Physics and the Geology Departments, Gauhati University, Assam, India during 1981-1984. Experimental results show four different age groups of the minerals which would reflect meaningful geological events in the history of these rocks. Sphenes of the Nartiang and Dawki granites record the highest FT ages ~ 1120 m.y. which may be linked with a major plutonic event. Muscovites of the Nartiang and Jowai pegmatites measure ages ~ 690 m.y. which may correspond to the time of emplacements of these pegmatites. Apatites of the Nartiang granites show FT ages ~ 470 m.y. which falls within the period of Indian Ocean cycle event. But, apatites of the Jowai, Pynursla and Dawki granites record the youngest ages ~ 90 m.y. which lies within the period of extrusion of cretaceous lavas (Sylhet traps). Apatite age of the Nartiang granite and muscovite ages of the Nartiang and Jowai pegmatites were corrected to ~ 510 m.y., ~ 743 m.y. and ~ 741 m.y. respectively by applying the plateau method of age correction. However, insignificant corrections were found in the sphene ages of the Nartiang and Dawki granites and apatite ages of the Jowai and Dawki granites. An interesting finding of the present work is the wide discrepancy between the apatite ages ~ 90 m.y. (Cretaceous) of Jowai, Pynursla

    Objectives This study sought to use a population-based cross-sectional survey to describe depression prevalence, healthcare seeking and associations with socioeconomic determinants in a district in North India. Setting This study was conducted in Sahaspur and Raipur, administrative blocks of Dehradun district, Uttarakhand, in July 2014. Participants A population-based sample of 960 people over the age of 18 years was selected in 30 randomised clusters after being stratified by rural:urban census ratios. Primary outcome measures The survey used a validated screening tool, Patient Health Questionnaire, to identify people with depression, and collected information regarding socioeconomic variables and help-seeking behaviours. Depression prevalence and health seeking behaviours were calculated, and multivariable logistic regression was used to assess associations between risk factors and depression. Results Prevalence of depression was 6% (58/960), with a further 3.9% (37/960) describing a depressive episode of over 2 weeks in the past 12 months. Statistically significant adjusted OR for depression of more than 2 were found for people who were illiterate, classified as Scheduled Caste/Tribe or Other Backward Castes, living in temporary material housing and who had recently taken a loan. While over three quarters of people with depression (79%) had attended a private or government general medical practitioner in the past 3 months, none had received talking therapy (100% treatment gap) and two people (3.3%) had been prescribed antidepressants. Conclusions There are clear associations between social, educational and economic disadvantage and depression in this population. Strategies that address the social determinants of depression, such as education, social exclusion, financial protection and affordable housing for all are indicated. To address the large treatment gap in Uttarakhand, we must ensure access to primary and secondary mental health providers who can

    The incidence/prevalence of tuberculosis (TB) is reported to be high in the Sahariya tribe of North Central India. The outbreaks of different drug-resistant isolates of Mycobacterium tuberculosis emphasized the need for continuous monitoring of resistance to anti-tuberculosis drugs. This study aimed to assess the profile of multidrug resistant TB among the Sahariya tribe and their non-tribal neighbors for first line drugs through field-based investigations. A total of 274 sputum positive pulmonary TB individuals were enrolled and studied for their drug susceptibility profile by the proportion method. A total of 21 cases from Sahariya and 6 from non-tribes were identified with MDR-TB. Thus Sahariya tribe showed a 1.95-fold increased risk of developing drug resistance than non-tribes. Significant differences were observed for developing drug sensitivity between Sahariya males and females when analyzed for resistance developed to any drug and overall drug resistance vs. sensitive isolates, respectively. A 4.46-fold risk was found for MDR-TB among the smokers of Sahariya tribe, whereas, the non-tribes did not show any significant association. The drug susceptibility profile developed in the present study indicates that drug-resistant tuberculosis is emerging as a serious public health concern in Sahariya tribe. Urgent and effective control measures and better management policies are needed for the prevention of MDR-TB in the tribe. Copyright © 2015 King Saud Bin Abdulaziz University for Health Sciences.

    Introduction Aesthetic and functional problems in the dentofacial complex among children are often attributed to the disturbances in the dentofacial growth and development. This can be recognized during routine dental visits. This study pursued to assess the occlusion of the primary dentition in three to five-year-old children. Aim To study the occlusal traits of the primary dentition in a group of three to five-year-old North Gujarat children of Mehsana district and the variation in their occlusion relative to age and gender in the same group. Materials and Methods The study was a cross-sectional survey based on clinical examination and photographic evaluation of the primary dentition, 383 preschool children aged three to five years who were randomly selected from preschools in Mehsana district, Gujarat, India, using a multistage sampling technique. The study group was evaluated for the several occlusal parameters that include primary molar relation based on Baume classification and canine relation, overjet, overbite were assessed using Foster and Hamilton criteria. Chi-square test was performed to carry out statistical analysis. The p-value<0.05 was taken as statistically significant. Results Out of 383 participants, 55.35% had flush terminal plane; 43.34% mesial step molar relationship and 1.31% distal step molar relationship, 63.2% had straight profile, 95.8% had Class I canine relationship, 71.3% primate spaces, 56.7% physiologic spaces. Flush terminal plane was common at three years while, mesial step at four to five years, and Class I canine relationship was prevalent in both age groups. Flush terminal plane was more common in female participants than the males. Amongst other occlusal characteristics, increased overbite and open bite were prevalent. Conclusion It was found that the flush terminal plane molar relationship, straight profile, Class I canine relationship, primate spacing, increased overbite and open bite predominated. PMID:28274054

    Vertical profiles of aerosol backscatter coefficient and depolarization ratio, obtained from the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite, were studied in the upper troposphere and lower stratosphere (UTLS) region over North India (21-30° N and 72-90° E), covering the highly polluted Indo-Gangetic Plain (IGP) for one-year period from December 2011 to November 2012. An enhanced aerosol layer was observed between 15 and 18 km altitude, in the vicinity of tropopause, with a broad layer depth of about 2 km. The aerosol layer showed strong seasonal, monthly as well as day and night time variability, with a peak value of backscatter coefficient during monsoon season (˜5.54 × 10-3 sr-1 in September). The corresponding depolarization ratio indicates anisotropic (non-spherical) nature of particles. The aerosol layer was found to be highly linked with the variability in tropopause height, showing a positive correlation between tropopause height and the height of maximum backscatter coefficient (correlation coefficient of 0.8). However, it was found to be negatively correlated with the integrated backscatter coefficient (IBC), with a correlation coefficient of 0.3. We further analyzed outgoing long-wave radiation (OLR) data during the study period to investigate the link between the observed enhanced aerosol layer in the UTLS region and prevailing deep convective activities over the study region. Low values of OLR during monsoon (about 214 W m-2) indicate the occurrence of deep convection over this region, which may cause a large-scale circulation-driven vertical transport of boundary-layer pollution into the atmosphere of UTLS region. Results may have potential implications for better understanding and assessing the chemical and radiative impacts of these aerosols in the tropical UTLS region.

    To document the effect of season and environmental pollution on UVB irradiance; and to estimate cutaneous vitamin D synthesis in village women in different seasons. Radiant UVB energy was measured by a spectroradiometer in different seasons and, in April and May, on successive days in open areas at the city outskirts, at a crowded inner-city area and the villages of our participants. Clothing, outdoor activity pattern and serum 25-hydroxycholecalciferol (25(OH)D) levels were documented. Rural north India, latitude 26·8°N. Pregnant women (n 139, aged 20-40 years). UVB irradiance ranged from 56 µW/cm2 in January to 470 µW/cm2 in June. Proportion of skin exposed was 18·5 % in summer and 9·5 % in winter. Mean (sd) daily duration of sun exposure was 3·2 (0·2) h during winter and 2·1 (0·4) h during summer. Cutaneous vitamin D synthesis was estimated to be 19·25 µg (770 IU) during winter and 37·25 µg (1490 IU) during summer. Mean (sd) serum 25(OH)D was 28 (15) nmol/l during winter (92 % of participants with 50 nmol/l). Mean (sd) UVB irradiance at peak summer was significantly higher at the open areas and in the villages than at the inner-city location (340 (45) and 310 (60) v. 250 (50) µW/cm2, P=0·03). In our population, at latitude 26·8°N, poor skin exposure is a limiting factor in all seasons. During winter, low UVB radiation energy also contributes. Particulate pollution limits UVB irradiance. Vitamin D supplementation during winter may be necessary.

    Columnar aerosol properties retrieved from Multi-Wavelength solar Radiometer (MWR) measurements during the period 2001-2010 over Dibrugarh (27.3°N, 94.6°E, 111 m amsl), North-Eastern India are analyzed to identify the types of aerosols in the atmospheric column. Highest Aerosol optical depth (AOD) characterizes the pre-monsoon (March-May), while lowest AOD has been observed during the post-monsoon (Oct-Nov) season. The Ångström exponent (α) indicates predominance of fine aerosols during post-monsoon and winter (Dec-Feb) and dominance of coarse mode in pre-monsoon and monsoon (June-Sept). NOAA HYSPLIT back trajectory analysis suggests that the seasonal heterogeneity in aerosol characteristics can be attributed to the varying contribution from different source regions. Using the relationship between AOD 500 and α, the aerosols can be classified into five main types viz. continental average (CA), marine continental average (MCA), urban/industrial and biomass burning (UB) and desert dust (DD) while the remaining cases are considered as unidentified or mixed type (MT). These aerosol types exhibit seasonal heterogeneity in their contribution depending upon variability in sources. In winter, local production contributes to observed appreciable CA aerosol type, while highest percentage of UB type is attributed to both local and transported aerosols. On the other hand, transported UB and DD types play a significant role in the pre-monsoon season. Post-monsoon season is indicative of background continental average aerosol condition with a significant contribution from CA and MCA aerosols. Monsoon aerosols couldn't be distinguished properly due to different particle growth processes like humidification, hygroscopic growth etc. and hence MT aerosol type is predominant in this season. This is the first ever attempt to classify aerosols over this environment.

    North Central Western Ghats in India comprises rich bio-cultural diversity and is also home to varied ethnomedicinal practices. The study was taken up for documentation and analysis of traditional knowledge regarding the practice and use of plants in the treatment of bone fracture. This is an effort to preserve the vanishing wealth of traditional knowledge. Key informants identified in a preliminary survey and collection of information was through semi structured, open ended interviews. The details on age, place of practice, experience of key informants and learning of practice, disease they treat and mode of diagnosis, storage and usage of plants were collected. The identity of plants and their information was confirmed through repeated guided transect walks in different seasons with the informants and focus group discussions. Identified plants were deposited at the herbaria of Regional Medical Research Centre, Belgaum. Forty four key informants providing treatment for bone fracture in this region were identified. Thirty eight plant species belonging to 24 families have been documented in the present study. Highest number of species representation is found in families Euphorbiaceae and Fabaceae. The habit of the species showed that 45% of the herbal drugs were obtained from trees, followed by herbs, shrubs and climbers and majority of plants used were collected from wild (76%). The stem or stem bark (33%) was most commonly used plant part to prepare medicine. Twenty six formulations of 30 plant species were directly used in treating bone fracture, where Cissus quadrangularis has the highest use-value (0.14). Eleven plants were found to be administered for bone strengthening, pain relieving, inflammation reduction and speedy recovery and Gmelina arborea has the highest use value (0.27). The results indicated the importance of traditional herbal practices in community for their health needs. Both conservational strategies and further validation studies are the need

    This is a retrospective study of the experience with extremity vascular trauma at a tertiary level referral centre in North India where the majority of the population lives in villages and the incidence of high-speed automobile accidents and civilian violence is low. The aim was to study the aetiology, pattern of injuries and the mortality and morbidity rates due to vascular trauma in our population. Data relating to 148 patients presenting with vascular trauma requiring surgical intervention other than amputation between January 1996 and December 2002 were collected retrospectively. There were 132 males and 16 females with a mean age of 39 years presenting to the casualty with a median delay of 9.3 h after injury. Blunt trauma accounted for 84% of the injuries with extremities involved in 88%. The brachial artery was the most common artery injured with the femoral next most common. Repair without graft interposition was done in 74% and autogenous vein grafts were used in 23% of cases. Comparison of our results with those that would have been obtained, had the recommendations of Mangled Extremity Severity Score (MESS) been followed, showed that this scoring system had low sensitivity and specificity for prediction of salvageability of limbs. Eight percent patients died due to associated visceral organ injuries. Complications occurred in 32% patients and amputation was required in 6% of patients after an initial surgical repair mainly due to inadequate functional recovery. Eighty-eight percent of the survivors with salvaged limbs were able to achieve full functional recovery. Judicious selection and appropriate intervention can result in satisfactory limb salvage with good functional outcomes even with delayed presentations.

    Introduction Elevated oxidative stress plays an important role in the pathogenesis of health disorders, like arthritis. Traditionally, Vespa affinis L., a common edible insect among many tribes in North-East India, is believed to have a beneficial role in extenuating health disorders, such as arthritis. The present study investigated the molecular mechanism underlying medicinal benefit of the Aqueous Extract of Vespa affinis L. (AEVA) against oxidative stress pathophysiology. Methods The free radical scavenging activities of AEVA were examined against DPPH, hydroxyl, and superoxide radicals and the effect on the activities of antioxidant enzyme (GST and CAT) was determined using both recombinant proteins and human plasma. The antioxidant potential of AEVA was again investigated using THP-1 monocytes. Results AEVA possesses a significant free radical scavenging activity as evident from the DPPH, superoxide, and hydroxyl radical scavenging assay. Incubation of AEVA (2.5, 5, 7.5, and 10 μg/μL) with the recombinant antioxidant enzymes, rGST and rCAT significantly increased the enzyme activities compared to those observed in corresponding enzyme alone or AEVA itself. AEVA supplementation (5, 7.5, and 10 μg/μL) also stimulates the activities of GST and CAT when incubated with human plasma. A cell culture study also confirmed the beneficial role of AEVA (0.8 and 1.2 μg/μL) which enhances the activities of GST and CAT, and also reduces the intercellular ROS production in monocytes treated with or without H2O2 and the effects are at par with what is observed in N-acetyl cysteine-treated cells. Conclusion The antioxidant potential of the aqueous extract of Vespa affinis L. may mediate its therapeutic activities in oxidative stress-associated health disorders. PMID:27195807

    We evaluated the frequency of antiphospholipid antibody syndrome (APS) in patients presenting with thrombosis of various vascular beds from North India and report the antibody profiles encountered. A retrospective analysis was performed on the laboratory results of aCL (anticardiolipin), aβ2 Gp1 (anti-βeta-2 glycoprotein 1) antibody and LAC (lupus anticoagulant) of 1222 consecutive patients referred to the coagulation laboratory work-up for a hypercoagulable/thrombophilic state over a period of 4 years between 2009 and 2013. LAC was screened with dRVVT (diluted Russel Viper Venom Test) and KCT (Kaolin clotting time), and aCL and aβ2 Gp1 antibodies with commercial enzyme-linked immunosorbent assy kits. The current APS criteria was satisfied in 3.85% of all patients and 4.2% of pediatric patients with thrombosis. The venous circulation was more frequently affected (59.6%). Cerebral arterial and intra-abdominal vein involvement was common. Transient antibody positivity was seen in 44 (3.6%) cases. aβ2 Gp1, aCL and LAC were positive in 95%, 54.5% and 23% of patients with APS, respectively, during the initial visit and 93.6%, 23% and 17%, respectively, during the follow-up visit. Persistent triple positivity was seen in only three cases. At initial testing, positivity for both aCL and aβ2 Gp1 was the most frequent pattern (38% of cases). aβ2 Gp1 antibody was the commonest antibody that was persistently positive in patients with thrombosis. Triple positivity for all antibodies had the highest specificity and positive predictive value to diagnose APS in the first visit, whereas aβ2 Gp1 antibody had the highest sensitivity and negative predictive value. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    Few accounts exist of programmes in low- and middle-income countries seeking to strengthen community knowledge and skills in mental health. This case study uses a realist lens to explore how a mental health project in a context with few mental health services, strengthened community mental health competence by increasing community knowledge, creating safer social spaces and engaging partnerships for action. We used predominantly qualitative methods to explore relationships between context, interventions, mechanisms and outcomes in the "natural setting" of a community-based mental health project in Dehradun district, Uttarakhand, North India. Qualitative data came from focus group discussions, participant observation and document reviews of community teams' monthly reports on changes in behaviour, attitudes and relationships among stakeholder groups. Data analysis initially involved thematic analysis of three domains: knowledge, safe social spaces and partnerships for action. By exploring patterns within the identified themes for each domain, we were able to infer the mechanisms and contextual elements contributing to observed outcomes. Community knowledge was effectively increased by allowing communities to absorb new understanding into pre-existing social and cultural constructs. Non-hierarchical informal community conversations allowed "organic" integration of unfamiliar biomedical knowledge into local explanatory frameworks. People with psycho-social disability and caregivers found increased social support and inclusion by participating in groups. Building skills in respectful communication through role plays and reflexive discussion increased the receptivity of social environments to people with psycho-social disabilities participation, thereby creating safe social spaces. Facilitating social networks through groups increases women's capacity for collective action to promote mental health. In summary, locally appropriate methods contribute most to learning

    Autoimmune thyroid diseases (AITD) encompass a number of conditions that have in common cellular and humoral responses targeting the thyroid gland. Interactions between susceptibility genes and environmental triggers are thought to initiate an autoimmune response to thyroid antigens leading to disease manifestation. Commencement of the disease in childhood leads to the presumption that genetics may have an important role in the causation of the disease. The present study was aimed at evaluating the human leucocyte antigen (HLA) encoded susceptibility to develop juvenile autoimmune thyroiditis (JAT) in patients from North India. We studied 48 consecutive patients of JAT along with 176 first-degree relatives for their thyroid function (FT4, TSH) and anti-thyroid peroxidase antibody status (AbTPO). HLA studies were carried out using serology for HLA-class I antigens and DNA analysis of HLA-class II alleles. The data were compared with a cohort of 308 ethnically matched healthy individuals. We observed overt hypothyroidism in 50% and AbTPO positivity in 70.8% of the index cases. Among the first-degree relatives, goitre was observed in 51.7%, thyroid dysfunction in 28.4% and AbTPO in 29.5% of individuals. Of the 37 relatives who underwent fine-needle aspiration cytology (FNAC), 60% had evidence of chronic lymphocytic thyroiditis (CLT). A strong positive association of HLA-DRB1*1404 was observed with the JAT (35.4%vs. 10.4%, chi2 = 19.8, Pc = 0.0001). We also observed a higher (72%, P = 0.03) paternal transmission of HLA-DRB1*1404 to affected offspring in comparison to unaffected offspring. HLA-DRB1*03 was also increased among JAT patients but did not reach statistical significance. These studies point towards an important role of immune modifying genes, such as HLA, in influencing susceptibility to juvenile-onset AITD.

    There is a paucity of data for DEL phenotype in the Indian population. Ours is a tertiary care Regional Blood Transfusion Centre in north India collecting more than 50,000 blood units out of which 8-9% are RhD negative donors. To determine the frequency of DEL phenotype in RhD negative blood donor population at our centre. A total of 200 RhD-negative blood donor samples were included in this study which was conducted over a period of 4 months (October 2013 to January 2014). All these blood samples were tested for extended Rh typing including C, E, c and e antigens and also for adsorption elution testing. The heat elution method at 56 °C in water bath for 10 minutes was utilized. The eluate and the last wash supernatant were used for indirect antiglobulin test against O RhD positive and O RhD negative cells by gel technique using the LISS Coombs' AHG gel cards (Biorad, Morat, Switzerland). Those donor samples which were found positive on adsorption elution testing were also further investigated by gel technique for Direct Antiglobulin test (DAT), Weak D testing and Auto Control test. Out of the total 200 Rh D negative donor samples tested, 3 (1.5%) samples were found to give positive result and, thus, were the DEL phenotypes. It was found that 20 (10%) donor samples were positive for C antigen, 5 (2.5%) for E antigen, 200 (100%) for c antigen and 200 (100%) for e antigen. Among the DEL negative (= 197), 193 (98%) were E antigen negative and only 4 (2%) were E antigen positive, whereas among the DEL positive samples (= 3), 2 (66.6%) were E antigen negative and 1 (33.3%) was E antigen positive. The C antigen positivity was only in 2 (66.6%) individuals in the DEL positive group and 178 (90.3%) in the DEL negative samples. All the three samples which were found to be positive as DEL phenotype also gave negative result for DAT, Weak D testing and Auto Control. The frequency of DEL phenotype in north Indian RhD negative donor population is 1.5%. Copyright

    Single-grain optically stimulated luminescence dating was applied to Late Quaternary sediments at two sites in the Middle Son Valley, Madhya Pradesh, India. Designated Bamburi 1 and Patpara, these sites contain Late Acheulean stone tool assemblages, which we associate with non-modern hominins. Age determinations of 140-120 ka place the formation of these sites at around the Marine Oxygen Isotope Stage 6-5 transition, placing them among the youngest Acheulean sites in the world. We present here the geochronology and sedimentological setting of these sites, and consider potential implications of Late Pleistocene archaic habitation in north-central India for the initial dispersal of modern humans across South Asia.

    Weather forecasting is an important issue in the field of meteorology all over the world. The pattern and amount of rainfall are the essential factors that affect agricultural systems. India experiences the precious Southwest monsoon season for four months from June to September. The present paper describes an empirical study for modeling and forecasting the time series of Southwest monsoon rainfall patterns in the North-East India. The Box-Jenkins Seasonal Autoregressive Integrated Moving Average (SARIMA) methodology has been adopted for model identification, diagnostic checking and forecasting for this region. The study has shown that the SARIMA (0, 1, 1) (1, 0, 1)4 model is appropriate for analyzing and forecasting the future rainfall patterns. The Analysis of Means (ANOM) is a useful alternative to the analysis of variance (ANOVA) for comparing the group of treatments to study the variations and critical comparisons of rainfall patterns in different months of the season.

    North-eastern region of India continue to suffer from limited resources, added upon by Mongoloid racial similarity and poor cataract surgery rate has contributed to the increase incidence of advanced cataract like phacomorphic glaucoma. To evaluate the visual prognosis and related complications of phacomorphic glaucoma cases by manual small incision cataract surgeries in North-eastern region of India. This retrospective case series study includes 65 phacomorphic glaucoma cases diagnosed between June 2009 to December 2011 in Jawaharlal Nehru Institute of Medical Sciences, Manipur. Preoperative routine evaluation includes slit-lamp biomicroscopy, measurement of IOP, gonioscopy of fellow eye, axial length measurement, AC depth and lens thickness by A-scan. Manual small incision cataract surgery with intraocular lens implantation was performed in all the 65 eyes. Complete ophthalmic examination was done at each follow-up visit. The mean preoperative IOP was 35.14 (±6.35) mm Hg and IOP at the 3rd month follow-up was 18.65 (±1.3) mm Hg with a statistically significant lowering of IOP (p < 0.0001) at the last follow-up. Intraoperative complications were minimal. Corneal edema, fibrinous exudates in AC was seen in few cases. Postoperative best corrected visual acuity was 6/6-6/12 in 46 eyes, 6/18-6/36 in 12 eyes, 6/60-3/60 in 4 eyes and less than 3/60 in three eyes.

    the CALIPSO algorithm, probably misclassifying marine aerosol as polluted dust. The origin of much of the polluted dust, the most prominent aerosol species in the region, is the mixing of dust and smoke from Africa. Low-level southerly winds south of 10°N transport smoke northward while northerly winds north of 10°N transport dust southward and upward due to orographic lifting. At their area of convergence, zonal wind transports the now elevated polluted dust eastward toward the Indian subcontinent. Subsidence and monsoon circulation reversal during boreal winter and fall limit vertical and horizontal aerosol transport from the India, particularly in the highly populated and always polluted Indo¬-Gangetic Plain. Polluted dust, polluted continental (non-elevated smoke), and smoke aerosols are confined near the surface and located over high population density areas and known biomass burning locations. Himalayan topography is an obvious barrier for the northward extent of aerosol. However, it also acts to create a meridional circulation limiting the southward extent of aerosol. Although transport pathways and the spatial structure of aerosol are well documented in the 2D sense, understanding the mechanisms controlling the vertical structure in concert with observation of the structure will be a valuable tool in reducing the uncertainty of aerosol effects in model simulations.

    Four years (2010-2014) of spectral aerosol optical depth (AOD) data from 4 Indian Space Research Organisation's ARFINET (Aerosol Radiative Forcing over India) stations (Shillong, Agartala, Imphal and Dibrugarh) in the North-Eastern Region (NER) of India (lying between 22-30°N and 89-98°E) are synthesized to evolve a regional aerosol representation, for the first time. Results show that the columnar AOD (an indicator of the column abundance of aerosols) is highest at Agartala (0.80 ± 0.24) in the west and lowest at Imphal (0.59 ± 0.23) in the east in the pre-monsoon season due to intense anthropogenic bio-mass burning in this region aided by long-range transport from the high aerosol laden regions of the Indo-Gangetic Plains (IGP), polluted Bangladesh and Bay of Bengal. In addition to local biogenic aerosols and pollutants emitted from brick kilns, oil/gas fields, household bio-fuel/fossil-fuel, vehicles, industries. Aerosol distribution and climatic impacts show a west to east gradient within the NER. For example, the climatological mean AODs are 0.67 ± 0.26, 0.52 ± 0.14, 0.40 ± 0.17 and 0.41 ± 0.23 respectively in Agartala, Shillong, Imphal and Dibrugarh which are geographically located from west to east within the NER. The average aerosol burden in NER ranks second highest with climatological mean AOD 0.49 ± 0.2 next to the Indo-Gangetic Plains where the climatological mean AOD is 0.64 ± 0.2 followed by the South and South-East Asia region. Elevated aerosol layers are observed over the eastern most stations Dibrugarh and Imphal, while at the western stations the concentrations are high near the surface. The climate implications of aerosols are evaluated in terms of aerosol radiative forcing (ARF) and consequent heating of the atmosphere in the region which follows AOD and exhibit high values in pre-monsoon season at all the locations except in Agartala. The highest ARF in the atmosphere occurs in the pre-monsoon season ranging from 48.6 Wm-2 in Agartala

    Background: Tattooing has become increasingly popular, particularly among young people. However, little is known about the tattoo practices in North-East India. Objectives: The primary objective of this study was to know the reasons and motivations of tattoo application and tattoo removal in individuals asking for tattoo removal. The secondary objective was to identify the demography, methods and safety of tattoo practices in these tattooed individuals. Materials and Methods: A hospital-based cross-sectional study was carried out in 212 consecutive individuals seeking tattoo removal. Chi-square and Fisher's exact tests were performed for intergroup comparisons. Results: There were 178 (84%) males and 34 (16%) females. The mean ± standard deviation (SD) age of individuals seeking tattoo removal was 21.8 ± 4 years. The mean ± SD age of doing tattoo was 15.8 ± 3 years. Most individuals possessed an amateur tattoo (94.3%), 4.2% a professional one and 1.4% had a combination. Sewing needle was the most common instrument used for making tattoos in 51.4%. The individuals made their tattoos in an unsterile manner in 49.1%. The most common reason for doing tattoo was for fashion in 87.7%. The participants wanted tattoo removal to qualify for jobs, especially in armed forces in 49.5% and due to regret in 21.7%. Black was the most preferred colour in 37.3% followed by green in 28.3%. The fabric ink was the choice of ink in maximum number of individuals, i.e. 93.9%. Limitations: It was a hospital-based study done only on individuals seeking tattoo removal. It needs caution to generalise the findings in population. In addition, there may be recall bias in the participants. Conclusion: The tattoo was done mostly below 18 years of age in a crude unsterile way. The individuals had poor risk perceptions about various infections and complications of tattooing. There is an urgent need to caution and educate the youngsters and school-going children about safe tattooing and

    Improving hydrological forecasting systems on different time scales is interesting and challenging with regards to humanitarian as well as scientific aspects. In meteorological research, short-, medium-, and long-term forecasts are now being merged to form a system of seamless weather and climate predictions. Coupling of these meteorological forecasts with a hydrological model leads to seamless predictions of streamflow, ranging from one day to a season. While there are big efforts made to analyse the uncertainties of probabilistic streamflow forecasts, knowledge of the single uncertainty contributions from meteorological and hydrological modeling is still limited. The overarching goal of this project is to gain knowledge in this subject by decomposing and quantifying the overall predictive uncertainty into its single factors for the entire seamless forecast horizon. Our study area is the Mahanadi River Basin in North-East India, which is prone to severe floods and droughts. Improved streamflow forecasts on different time scales would contribute to early flood warning as well as better water management operations in the agricultural sector. Because of strong inter-annual monsoon variations in this region, which are, unlike the mid-latitudes, partly predictable from long-term atmospheric-oceanic oscillations, the Mahanadi catchment represents an ideal study site. Regionalized precipitation forecasts are obtained by applying the method of expanded downscaling to the ensemble prediction systems of ECMWF and NCEP. The semi-distributed hydrological model HYPSO-RR, which was developed in the Eco-Hydrological Simulation Environment ECHSE, is set up for several sub-catchments of the Mahanadi River Basin. The model is calibrated automatically using the Dynamically Dimensioned Search algorithm, with a modified Nash-Sutcliff efficiency as objective function. Meteorological uncertainty is estimated from the existing ensemble simulations, while the hydrological uncertainty is

    Globally, measles is the fifth killer disease among children under five years of age. Despite high immunization coverage in Himachal, outbreaks are occurring. Upon two outbreaks in a hilly district in North India, a case control study was conducted to identify factors contributing to outbreaks and to recommend remedial measures to prevent further outbreaks. FACTORS WERE REVIEWED UNDER THREE HEADS: program related, health care providers, and beneficiaries related. Cold chain maintenance was determined and responses were compared between workers from study Shahpur and control Nagrota Bagwan blocks. All 69 mothers of age and sex matched children with measles were enrolled. A pre-designed pre-tested data collection instrument was used. For statistical analysis, the odds ratio (OR) and adjusted odds ratio with 95% confidence interval (C.I.) among women of children exposed and unexposed to selected characteristics were calculated. Poor cold chain maintenance and gaps in knowledge of health workers supplemented with beneficiary-related issues precipitated outbreaks in case area. Univariate analysis yielded strong statistical significance to 17 variables.

    Vegetative and reproductive phenology of Barringtonia acutangula, a floodplain tree species was studied at Chatla floodplain, Assam North East India with the aim to investigate vegetative and reproductive phenology under stressful environment of seasonal submergence and to assess the impact of environmental variables (temperature and precipitation) on tree phenophases. Quantitative assessment was made at 15 day interval for all the phenophases (leaf initiation, leaf-fall, flowering and fruiting) by tagging 40 (forty) trees over aperiod of two years (2012-14).To test seasonal influence on the phenology of Barringtonia acutangula different phenophases were correlated with environmental variables and statistical spearman's rank correlation coefficient was employed. Aridity index was computed that delineate influence of rainfall and temperature together on any phenophases. Leaf initiation showed positively significant correlation with temperature (r(s) = 0.601, p = < .05) during the year 2012-2013 whereas it was significantly correlated with rainfall (r(s) = 0.583, p = < .05) and aridity index (r(s) = 0.583, p = < .05) during the year 2013-2014. Leaf-fall was significant negatively correlated with temperature (r(s) = -0.623, p = < .05), rainfall (r(s) = -0.730, p = < .01) and aridity index (r(s) = -0.730, p = < .01) for both the studied years. Flowering was significantly influenced by temperature (r(s) = 0.639, p = < .05), rainfall (r(s) = 0.890, p = < .01) and aridity index (r(s) = 0.890, p = < .01) while in one month lag flowering was significantly correlated with rainfall (r(s) = 0.678, p = < .01) in 2012-13. Fruiting was also positively significant with temperature (r(s) = 0.795, P < .05), rainfall (r(s) = 0.835, P < .01) and aridity index (r(s) = 0.835, P < .01) for both the years. During one month lag period fruiting was positively correlated with temperature, rainfall and aridity index in both the years. Temperature, rainfall and aridity index were major

    Obesity is an increasingly important health problem worldwide as well as in developing countries like India. Recent genetic studies suggest that obesity associated FTO and IRX3 are functionally linked and many effects due to genetic variants in FTO gene act through IRX3. To evaluate the association of FTO and IRX3 genetic variants towards obesity risk. North Indian individuals categorised as non-obese (BMI < 30 kg/m(2)) and obese (BMI ≥ 30 kg/m(2)) were selected. FTO rs8050136, rs1421085, rs9939609, rs17817449 and IRX3 rs3751723 were genotyped by means of validated Taqman® allelic discrimination to evaluate their association with obesity by means of single locus logistic regression by SPSS ver. 19 and multi-locus linkage and haplotype analysis by SNPStats and gene-gene interaction with Generalised Multifactor Dimensionality Reduction (GMDR) ver.6. In single locus analysis, FTO rs8050136 CA (p = 0.0001; OR (95% CI) = 2.4 (1.7-3.4) and AA (p = 0.0001; OR (95% CI) = 3.1 (1.9-5.2); FTO rs1421085 TA (p = 0.0001; OR (95% CI) = 2.1 (1.4-3.0) and AA (p = 0.0001; OR (95% CI) = 3.0 (1.8-5.0); FTO rs9939609 TC (p = 0.0001; OR (95% CI) = 2.1 (1.5-3.1) and CC (p = 0.0001; OR (95% CI) = 4.2 (2.5-7.3) along with TG (p = 0.001; OR (95% CI) = 2.1 (1.3-3.2) and GG (p = 0.021; OR (95% CI) = 3.8 (1.2-11.8) genotypes of FTO rs17817449 with GT (p = 0.0001; OR (95% CI) = 2.1 (1.5-3.1) and TT (p = 0.012; OR (95% CI) = 3.3 (1.8-3.6) genotypes of IRX3 rs3751723 were significantly associated with obesity. In multi-locus analysis, SNPs of FTO and IRX3 were in strong linkage disequilibrium and in haplotype and GMDR analysis the SNPs were significantly associated with obesity risk (p < 0.05). This is the first study to reveal that genetic variants of both FTO and IRX3 genes are in high linkage disequilibrium (LD) and are associated with obesity risk in North Indians.

    The population of Sikkim is a unique blend of multi-tribal and metropolitan culture. However, till date, no data regarding prevalence of sexually transmitted diseases (henceforth abbreviated as STDs) among this population is available and hence requires attention. Hence the objective is to determine the prevalence of STDs in Sikkim and to describe associated risk factors. A cross-sectional study involving 'Questionnaire-based anonymous feedback system' was followed to collect data from 2,000 individuals across the society. The four most common STDs, gonorrhea, syphilis, chlamydia and HIV, were considered for the study. Total 69 (3.6%) cases of STDs were found in 1,918 individuals was affected by at least one of the STDs, out of which 43 were males and 26 were females. Cases of gonorrhea, syphilis, chlamydiasis and HIV were 25, 22, 4 and 18 respectively. Out of total 69 cases of STDs, 20 individuals were also suffering from some kind of hepatitis. Addictions like alcoholism, smoking and drugs were also found in significant number, with 1,019 (>50%) individuals with at least one of these addictions. Relative risk analysis indicates that gender-wise females are more vulnerable to STDs than males. The number of partners, addictions, especially alcohol and drug abuse, also contribute to STD cases. STDs act as a significant risk factor in transmitting some of the types of hepatitis. In such cases, females are more vulnerable than males. The results suggest that new community health programs are essential for both, HIV and non-HIV STDs in Sikkim.

Stemflow leachates formed the main source of ammonium-N and nitrate-N for uptake by these orchids. Phosphorus concentration in the tissues of these orchids was high. Phosphate-P from stemflow does not seem to be a regular source of phosphorus for these orchids. Absorption/desorption results indicate that organic-N from stemflow leachates is not utilized by these orchids. PMID:21247907

    Peste-des-petits- ruminants (PPR) is a highly contagious and devastating disease of goats and sheep. Although India is endemic for PPR, Tripura, a state in North East India has never been reported confirmed PPR outbreaks. Recently, an outbreak of PPR occurred in non-descript goats at the Sabroom town of Tripura state in North-East India in June, 2013. The causative agent, PPR virus (PPRV) was confirmed by sandwich ELISA, virus isolation and N gene based RT-PCR and sequencing. The sequence and phylogenetic analysis confirmed the involvement of lineage IV PPR virus in the outbreak. The outbreak viruses from Tripura state were clustered mainly with circulating viruses from Bangladesh, India, China, Pakistan, Tajikistan, Dubai and Kurdistan. However, the nucleotide sequence homology ranged from 99.2 to 99.6% with the PPR strains circulating in Bangladesh during 2011 and 2012 whereas 95.5-98% homology has been observed with the viruses from India and other countries. These findings suggest the transboundary circulation of PPR virus between India and Bangladesh border, which warrant immediate vaccination across the international border to create an immune belt.

    There is an extreme paucity of studies examining cost of burn care in the developing world when over 85% of burns take place in low and middle income countries. Modern burn care is perceived as an expensive, resource intensive endeavour, requiring specialized equipment, personnel and facilities to provide optimum care. If 'burn burden' of low and middle income countries (LMICs) is to be tackled deftly then besides prevention and education we need to have burn centres where 'reasonable' burn care can be delivered in face of resource constraints. This manuscript calculates the cost of providing inpatient burn management at a large, high volume, tertiary burn care facility of North India by estimating all cost drivers. In this one year study (1st February to 31st January 2012), in a 50 bedded burn unit, demographic parameters like age, gender, burn aetiology, % TBSA burns, duration of hospital stay and mortality were recorded for all patients. Cost drivers included in estimation were all medications and consumables, dressing material, investigations, blood products, dietary costs, and salaries of all personnel. Capital costs, utility costs and maintenance expenditure were excluded. The burn unit is constrained to provide conservative management, by and large, and is serviced by a large team of doctors and nurses. Entire treatment cost is borne by the hospital for all patients. 797 patients (208 <12 years old) with acute burn were admitted with a mean age of 23.04 years (range 18 days to 83 years). The mean BSA burn was 42.26% (ranging from 2% to 100%). 378/797 patients (47.43%) sustained up to 30% BSA burns, 216 patients (27.1%) had between 31 and 60% BSA and 203 patients (25.47%) had >60% BSA burns. 258/797 patients died (32.37%). Of these deaths 16, 68 and 174 patients were from 0 to 30%, 31 to 60% and >60% BSA groups, respectively. The mean length of hospitalization for all admissions was 7.86 days (ranging from 1 to 62 days) and for survivors it was 8.9 days

    Esophageal cancer is one of the most common cancers in North East India. The molecular mechanisms of esophageal cancer susceptibility in North East India have not been fully understood. There is a need for identification of biomarkers to identify people at risk of esophageal cancer. p16 is an essential G1 cell cycle regulatory gene whose loss of function is associated with carcinogenesis. Therefore, we conducted this study to determine the prevalence of p16 gene methylation in patients with esophageal cancer to assess the feasibility of using gene methylation as a biomarker. A total of 100 newly diagnosed esophageal cancer cases along with equal number of age, sex, and ethnicity-matched controls were included in this study. Methylation-specific PCR was used to determine the p16 methylation status. Aberrant promoter methylation of the p16 gene was detected in 81 of 100 (81%) esophageal cancer cases. Hypermethylation of p16 gene was found to be influenced by lifestyle factors. Betel quid and tobacco chewing habit synergistically with p16 methylation elevated the risk for esophageal cancer development (adjusted odds ratio (OR) = 6.88, 95% confidence interval (CI) = 1.64-28.81, p = 0.003 for betel quid chewing and adjusted OR = 7.02, 95% CI = 1.87-26.38, p = 0.001 for tobacco chewing). Further, intake of green leafy vegetables and fruits lowered the risk of esophageal cancer (adjusted OR = 0.16, 95 % CI = 0.04-0.58, p = 0.05 for green leafy vegetables and adjusted OR = 0.15, 95% CI = 0.04-0.64, p = 0.01 for fruits). Thus, p16 hypermethylation may aid as a biomarker in identifying habitués at greater risk for esophageal cancer susceptibility in high incidence region of North East India.

    The World Health Organization (WHO) has in 2013 changed the diagnostic criteria for gestational diabetes mellitus (GDM) to acknowledge the putative effect of mildly elevated fasting plasma glucose (FPG) levels on pregnancy outcomes. We aimed to determine the prevalence and risk factors of GDM comparing the previous WHO 1999 criteria to the WHO 2013 criteria in North India. In a population-based screening programme, 5100 randomly selected North Indian women were studied using a cross-sectional design with a questionnaire, venous FPG and 2-h capillary plasma glucose (PG) after a 75 g oral glucose tolerance test performed between 24 and 28 weeks of pregnancy. The prevalence of GDM was 35% using WHO 2013 criteria vs 9% using WHO 1999 criteria. FPG measurements identified 94% of WHO 2013 GDM cases as opposed to 11% of WHO 1999 GDM cases. In contrast, 2-h PG measurements identified only 13% of WHO 2013 GDM cases compared with 96% of the WHO 1999 GDM cases. Using logistic regression with backward elimination, urban habitat, illiteracy, non-vegetarianism, increased BMI, Hindu religion and low adult height were all independent risk factors of GDM using the 1999 criteria, whereas only urban habitat, low adult height and increased age were independent risk factors of GDM using the 2013 criteria. Intervention studies are needed to justify the WHO 2013 GDM criteria increasing the prevalence four fold to include more than one third of North Indian pregnant women. © 2015 European Society of Endocrinology.

    Manipur State, with a population of 2.29 million, is one of the seven North-Eastern Hill states in India, and is severely affected by groundwater arsenic contamination. Manipur has nine districts out of which four are in Manipur Valley where 59% of the people live on 10% of the land. These four districts are all arsenic contaminated. We analysed water samples from 628 tubewells for arsenic out of an expected total 2,014 tubewells in the Manipur Valley. Analyzed samples, 63.3%, contained >10 μg/l of arsenic, 23.2% between 10 and 50 μg/l, and 40% >50 μg/l. The percentages of contaminated wells above 10 and 50 μg/l are higher than in other arsenic affected states and countries of the Ganga-Meghna-Brahmaputra (GMB) Plain. Unlike on the GMB plains, in Manipur there is no systematic relation between arsenic concentration and the depth of tubewells. The source of arsenic in GMB Plain is sediments derived from the Himalaya and surrounding mountains. North-Eastern Hill states were formed at late phase of Himalaya orogeny, and so it will be found in the future that groundwater arsenic contamination in the valleys of other North-Eastern Hill states. Arsenic contaminated aquifers in Manipur Valley are mainly located within the Newer Alluvium. In Manipur, the high rainfall and abundant surface water resources can be exploited to avoid repeating the mass arsenic poisoning that has occurred on the GMB plains.

    Long-term impacts of drinking chlorinated water on the incidence of cancers and other adverse health outcomes were assessed in a population-based cross-sectional study. The study was conducted by comparing a group exposed to chlorinated drinking water for more than thirty years with control groups with less or no exposure to chlorine. A house-to-house survey was completed to gather information on residential history, age, education, income, source and extent of treatment of water and health characteristics. All residents below thirty years of age were excluded from the database used for analyses to ensure that the groups were comparable. Fourteen cancer cases were found in the long-term exposed groups of 1085 persons and 9 cancer cases in the two control populations of 725 persons. The odds ratio for cancers (OR) was 1.05 (95% CI = 0.43-2.65) and is not statistically significant. Reciprocal or inverse odds [corrected] ratios for gastrointestinal disorders, kidney problems and skin infections were statistically significant ranging from 2.06 (95% CI = 1.01-4.17) to 2.2 (95% CI = 1.45-3.33). These OR values indicate that there is no significant association between the incidence of cancer and exposure to chlorinated water while chlorinating drinking water significantly reduced the incidence of non-carcinogenic adverse health effects like gastrointestinal diseases, skin infections, and kidney diseases.

    Biomass burning causes intense perturbations to regional atmospheric chemistry and air quality and is a significant global source of reactive pollutants to the atmosphere (Andreae and Merlet, 2001). In November 2012, large areas in North India including New Delhi experienced several weeks of aggravated smog and poor air quality due to the impact of crop residue burning, which is a biannual post harvest activity that occurs during Oct-Nov and April-May every year in the agricultural belts of North western India. In-situ high temporal resolution (1 measurement every minute) measurements of a suite of volatile organic compounds measured using proton transfer reaction mass spectrometry (PTR-MS) such as acetonitrile (biomass burning tracer) and aromatic hydrocarbons were performed simultaneously with carbon monoxide, nitrogen oxides, ozone and aerosol mass concentrations (PM 2.5 and PM 10) at a suburban site (30.667°N, 76.729°E and 310 m asl), impacted by air masses that had passed over the burning fields less than 72 hours ago. By using data from the same season but before the post harvest crop residue burning activity had commenced, we were able to quantify enhancements in ambient levels of the measured species due to the crop residue burning activity. When air masses influenced by the fire emissions reached the measurement site, peak values of about 8 ppbV acetonitrile, 4 ppmV CO, 100 ppbV NOx , 30 ppbV toluene and 15 ppbV benzene were observed which represented a factor of 2-5 increase over their ambient levels in the non-fire influenced period. Emission ratios of aromatic hydrocarbons/CO also showed a marked increase. Non fire event (N.F. E.) influenced and fire event (F.E.) influenced air masses had the following emission ratio enhancements: benzene/CO (N.F.E = 3; F.E. = 5), toluene/CO (N.F.E = 4; F.E. = 8.7) and sum of C8 aromatics/CO (N.F.E = 4; F.E. = 7.3) and sum of C9 aromatics/CO (N.F.E = 2.6; F.E. = 3.4).

    North-East (NE) India, the probable origin of rice has diverse genetic resources. Many rice landraces of NE India were not yet characterized for blast resistance. A set of 232 landraces of NE India, were screened for field resistance at two different hotspots of rice blast, viz., IIRR-UBN, Hyderabad and ICAR-NEH, Manipur in two consecutive seasons. The phenotypic evaluation as well as gene profiling for 12 major blast resistance genes (Pitp, Pi33, Pi54, Pib, Pi20, Pi38, Pita2, Pi1, Piz, Pi9, Pizt, and Pi40) with linked as well as gene-specific markers, identified 84 resistant landraces possessing different gene(s) either in singly or in combinations and also identified seven resistant landraces which do not have the tested genes, indicating the valuable genetic resources for blast resistance. To understand the molecular diversity existing in the population, distance and model based analysis were performed using 120 SSR markers. Results of both analyses are highly correlated by forming two distinct subgroups and the existence of high diversity (24.9% among the subgroups; 75.1% among individuals of each subgroup) was observed. To practically utilize the diversity in the breeding program, a robust core set having an efficiency index of 0.82 which consists of 33 landraces were identified through data of molecular, blast phenotyping, and important agro-morphological traits. The association of eight novel SSR markers for important agronomic traits which includes leaf and neck blast resistance was determined using genome-wide association analysis. The current study focuses on identifying novel resources having field resistance to blast as well as markers which can be explored in rice improvement programs. It also entails the development of a core set which can aid in representing the entire diversity for efficiently harnessing its properties to broaden the gene pool of rice.

    The North West region of India is extremely important to understand the peopling of India, as it acted as a corridor to the foreign invaders from Eurasia and Central Asia. A series of these invasions along with multiple migrations led to intermixture of variable populations, strongly contributing to genetic variations. The present investigation was designed to explore the genetic diversities and affinities among the five major ethnic groups from North West India; Brahmin, Jat Sikh, Bania, Rajput and Gujjar. A total of 327 individuals of the abovementioned ethnic groups were analyzed for 4 Alu insertion marker loci (ACE, PV92, APO and D1) and a Single Nucleotide Polymorphism (SNP) rs2234693 in the intronic region of the ESR1 gene. Statistical analysis was performed to interpret the genetic structure and diversity of the population groups. Genotypes for ACE, APO, ESR1 and PV92 loci were found to be in Hardy-Weinberg equilibrium in all the ethnic groups, while significant departures were observed at the D1 locus in every investigated population after Bonferroni's correction. The average heterozygosity for all the loci in these ethnic groups was fairly substantial ranging from 0.3927 ± 0.1877 to 0.4333 ± 0.1416. Inbreeding coefficient indicated an overall 10% decrease in heterozygosity in these North West Indian populations. The gene differentiation among the populations was observed to be of the order of 0.013. Genetic distance estimates revealed that Gujjars were close to Banias and Jat Sikhs were close to Rajputs. Overall the study favored the recent division of the populations of North West India into largely endogamous groups. It was observed that the populations of North West India represent a more or less homogenous genetic entity, owing to their common ancestral history as well as geographical proximity.

    In this study, source parameters of the September 18, 2011 M w 6.9, Sikkim earthquake were determined using acceleration records. These parameters were then used to generate strong motion at a number of sites using the stochastic finite fault modeling technique to constrain the causative fault plane for this earthquake. The average values of corner frequency, seismic moment, stress drop and source radius were 0.12 Hz, 3.07 × 1026 dyne-cm, 115 bars and 9.68 km, respectively. The fault plane solution showed strike-slip movement with two nodal planes oriented along two prominent lineaments in the region, the NE-oriented Kanchendzonga and NW-oriented Tista lineaments. The ground motions were estimated considering both the nodal planes as causative faults and the results in terms of the peak ground accelerations (PGA) and Fourier spectra were then compared with the actual recordings. We found that the NW-SE striking nodal plane along the Tista lineament may have been the causative fault for the Sikkim earthquake, as PGA estimates are comparable with the observed recordings. We also observed that the Fourier spectrum is not a good parameter in deciding the causative fault plane.

    Asian pika species are morphologically ∼similar and have overlapping ranges. This leads to uncertainty and species misidentification in the field. Phylogenetic analyses of such misidentified samples leads to taxonomic ambiguity. The ecology of many pika species remains understudied, particularly in the Himalaya, where sympatric species could be separated by elevation and/or substrate. We sampled, measured, and acquired genetic data from pikas in the Sikkim Himalaya. Our analyses revealed a cryptic lineage, Ochotona sikimaria, previously reported as a subspecies of O. thibetana. The results support the elevation of this lineage to the species level, as it is genetically divergent from O. thibetana, as well as sister species, O. cansus (endemic to central China) and O. curzoniae (endemic to the Tibetan plateau). The Sikkim lineage diverged from its sister species' about 1.7-0.8myrago, coincident with uplift events in the Himalaya. Our results add to the recent spate of cryptic diversity identified from the eastern Himalaya and highlight the need for further study within the Ochotonidae. Copyright © 2016 Elsevier Inc.

    During a survey of edible Crustacea for recovery of infective stages (metacercariae) of potential helminthozoonoses of trematode origin in north-east India, the crab species Barytelphusa lugubris mansoniana, collected from suspected foci of lungfluke infection in Meghalaya and Assam, was found to harbour metacercarial cysts that were different from the earlier reported infection, in which the lungfluke Paragonimus was confirmed to be implicated. Using morphological criteria, this metacercaria was identified as Microphallus indicus Mukherjee & Ghosh, 1967 of the trematode family Microphallidae. The present study extends the previous work by providing molecular characterization of this parasite using ribosomal internal transcribed spacer regions (rDNA ITS1 and ITS2) and the partial large ribosomal subunit DNA, lsr. These target regions were amplified by polymerase chain reaction (PCR) using trematode universal primers and sequenced. In BLAST analysis the query sequences were found close to members of Microphallidae and closest to the genus Microphallus.

    Antioxidant activities of the n-hexane, ethyl acetate and methanol extracts of three indigenous leafy vegetables of north east India viz., Polygonum microcephallum, Oxalis corniculata and Portulaca oleraceae were measured by spectroscopic methods using the 1, 1-diphenyl-2-picrylhydrazyl (DPPH*) radical assay and xanthine/xanthine oxidase assay. The total phenolic and total flavonoid contents of each extract were also measured to assess their effect on the antioxidant activity. It was observed that the methanol extracts of all the species showed the highest antioxidant activities and high values for total phenolic and flavonoid contents. A strong correlation between the antioxidant activities and the total phenolic content was observed for the three vegetables. It indicates that phenolics are one of the main components responsible for the antioxidant behavior of vegetables. HPLC analysis showed the presence of a number of identified phenolic compounds.

    In this study, mineral magnetic properties and petroleum hydrocarbons were statistically analysed in four sediment cores (C1, A1, T1 and K1) from the north east coast of Tamilnadu, India to examine the feasibility of PHC concentrations assessment using magnetic susceptibility. The C1 and A1 cores reveal a clear horizon of increase in PHC above 35 and 50 cm respectively suggesting the excess anthropogenic loading occurred in the recent past. Magnetic properties which were enhanced in the upper part of the sediment cores were the result of ferrimagnetic minerals from anthropogenic sources. Factor analysis confirmed that the input of magnetic minerals and petroleum hydrocarbons in Chennai coastal sediments are derived from the same sources. The present study shows that instead of expensive and destructive PHC chemical methods, magnetic susceptibility is found to be a suitable, cheap and rapid method for detailed study of petroleum hydrocarbon contamination in marine sediments.

    In the hilly tropics, although shifting cultivation is a widespread practice, government policies have attempted to replace it with other land uses. However, several factors determine whether farming communities can make the shift. We tried understanding the factors that facilitate or impede the shift to settled cultivation through interviews with the Adi tribe in north-east India. Although settled cultivation was initiated in the 60s, about 90 % of the families still practise shifting cultivation, observing 13 festivals associated with the annual agricultural calendar. Our results indicate that the economic status of a household determined whether a family undertook settled cultivation, while labour availability was important for shifting cultivation. Often, these nuances are ignored in the Government policies. We conclude that future policies should be mindful of cultural and socio-economic factors that affect the community and of the social-ecological resilience of the landscapes and not use a one-size-fits-all strategy.

    Lymphoma of the uterine cervix is very rare. We report a case of diffuse large B cell lymphoma (DLBCL) involving the uterine cervix treated at a newly commissioned semiurban cancer centre in north India in 2015. Data for this study was obtained from the hospital electronic medical records and the patient's case file. We also reviewed published case reports of uterine and cervical lymphoma involving forty-one patients. We treated a case of stage IV DLBCL cervix with six cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) and intrathecal methotrexate followed by consolidation with radiotherapy. The patient showed complete response to chemotherapy. We conclude that, in advanced stage lymphoma involving uterus and cervix, combination of chemotherapy and radiotherapy is effective in short term. PMID:27597906

    The accumulation of heavy metals such as lead (Pb), iron (Fe), zinc (Zn), cadmium (Cd), and chromium (Cr) was examined in crab (Scylla serrata) and shrimps (Penaeus semisulcatus, Penaeus indicus, and Penaeus monodon) collected from Pulicat lake that receives effluents from industries located in north Chennai, southeast coast of India. The results showed limited difference between crab and prawns as well as significant variations between the organs. Pb is the highly accumulated metal in both crab and shrimps, except P. monodon. The highest metal concentration was mostly found in the liver followed by other organs. The concentration of metals in edible parts (muscle) was within the permissible level and safe for consumption. However, the results of the study clearly indicate the biomagnification of metals in Pulicat lake.

    A cross-sectional survey was conducted in the Integrated Child Development Scheme (ICDS) to assess the sexual behavior patterns and knowledge of sexually transmitted diseases (STDs) among 15-21 year old boys with a goal of developing a community-based reproductive educational health program in India. About 221 boys from 35 Anganwadi centers were interviewed twice; on the first interview the educational, socioeconomic and marital status was determined, while questions about their health, substance abuse, sexual activity, condom use, number of sexual partners, and STD symptoms were asked during the second interview. Findings revealed that premarital sex was practiced by 7.9% and 7.6% of boys aged 18 or younger and over 18, respectively, living in the urban slum areas of Lucknow, North India. The boys engaged in high-risk sexual behavior and had a poor knowledge of STD symptoms and prevention. Furthermore, substance use has been associated with irregular condom use and also with STDs. These findings reveal that there is an urgent need for initiating reproductive health counseling programs targeted at these high-risk adolescents.

    Neonatal septicaemia is a clinical entity that is characterised by systemic signs and symptoms of infection and accompanied by bacteraemia in first 4 weeks of life and is one of the four leading causes of neonatal mortality and morbidity in India. To determine the bacterial spectrum and antimicrobial susceptibility pattern of neonatal septicaemia in a tertiary care hospital of North India. In this prospective observational study, 850 blood samples were collected and processed from clinically suspected neonates according to standard laboratory protocol. Antimicrobial susceptibility of the isolates was done by Kirby Bauer disc diffusion method according to Clinical and Laboratory Standard Institution (CLSI) recommendations. Blood culture reports were positive in 322 (37.8%) cases. Early onset sepsis (EOS) was present in 61.41% and late onset sepsis (LOS) in 38.59% of cases. Gram-negative septicaemia (60.67%) was encountered more than Gram-positive (32.01%). Coagulase negative Staphylococci (17.43%) was the predominant isolate followed by, Klebsiella spp in 16.11% cases. Best overall sensitivity among Gram-negative isolates was to Colistin (89.94%), Imipenem (86.43%) and Meropenam (77.88%). Gram-positive isolates had good (97.15%) sensitivity to linezolid, (95.23%) vancomycin and (88.57%) Teicoplanin. Gram-negative organisms are the leading cause of neonatal septicaemia with Klebsiella spp being commonest. Coagulase negative Staphylococci is the predominant isolate among Gram-positive organisms. Most of the isolates are resistant to common antibiotics.

    The present study aimed to examine the association of PPARγ (p.Pro12Ala) polymorphism with type 2 diabetic retinopathy (DR) in patients from north India. In this case-control association study a total of 1325 subjects (717 DR patients and 608 individuals with confirmed type 2 diabetes mellitus (T2DM) without retinopathy taken as controls (CDR)), were recruited. Genotyping for PPARγ (p.Pro12Ala) polymorphism was performed by Taqman SNP Genotyping Assays using Real time PCR. Statistically significant differences were observed between the two analyzed groups in the duration of diabetes and random blood glucose levels (p = 0.000 and p = 0.011, respectively). However, genotype and allele frequency distribution of PPARγ (p.Pro12Ala) polymorphism did not differ significantly between DR and CDR groups (p = 0.507 and 0.625, respectively). These findings suggest no significant association of p.Pro12Ala polymorphism with retinopathy in tested type 2 diabetic retinopathy patients as compared to T2DM individuals take as controls. To our knowledge, this is the first report of association analysis of p.Pro12Ala polymorphism in PPARγ in DR patients from India.

    We present crustal anisotropy estimates constrained by shear wave splitting (SWS) analysis using local earthquakes in the Shillong plateau and Assam valley area, North East India (NE India) region. Splitting parameters are determined using an automated cross-correlation (CC) method. We located 330 earthquakes recorded by 17 broadband seismic stations during 2001-2014 in the study area. Out of these 330 events, seismograms of 163 events are selected for the SWS analysis. Relatively small average delay times (0.039-0.084 s) indicate existence of moderate crack density in the crust below the study area. It is found that fast polarization directions vary from station to station depending on the regional stress system as well as geological conditions. The spatial pattern of crustal anisotropy in the area is controlled mostly by tectonic movement of the Indian plate towards NE. Presence of several E-W and N-S trending active faults in the area also play an important role on the observed pattern of crustal anisotropy.

    Diversity of culturable bacterial populations within the Arsenic (As) contaminated groundwater of North Eastern state (Assam) of India is studied. From nine As contaminated samples 89 bacterial strains are isolated. 16S rRNA gene sequence analysis reveals predominance of Brevundimonas (35%) and Acidovorax (23%) along with Acinetobacter (10%), Pseudomonas (9%) and relatively less abundant (<5%) Undibacterium, Herbaspirillum, Rhodococcus, Staphylococcus, Bosea, Bacillus, Ralstonia, Caulobacter and Rhizobiales members. High As(III) resistance (MTC 10-50 mM) is observed for the isolates obtained from As(III) enrichment, particularly for 3 isolates of genus Brevundimonas (MTC 50 mM). In contrast, high resistance to As(V) (MTC as high as 550 mM) is present as a ubiquitous property, irrespective of isolates' enrichment condition. Bacterial genera affiliated to other groups showed relatively lower degree of As resistance [MTCs of 15-20 mM As(III) and 250-350 mM As(V)]. As(V) reductase activity is detected in strains with high As(V) as well as As(III) resistance. A strong correlation could be established among isolates capable of reductase activity and siderophore production as well as As(III) tolerance. A large number of isolates (nearly 50%) is capable of anaerobic respiration using alternate inorganic electron acceptors [As(V), Se(VI), Fe(III), [NO(3)(2), SO(4)(2), S(2)O(3)(2). Ability to utilize different carbon sources ranging from C2-C6 compounds along with some complex sugars is also observed. Particularly, a number of strains is found to possess ability to grow chemolithotrophically using As(III) as the electron donor. The study reports for the first time the identity and metabolic abilities of bacteria in As contaminated ground water of North East India, useful to elucidate the microbial role in influencing mobilization of As in the region.

    There is not much published literature on neonatal septicemia available for the Sub-Himalayan region of North India. Hence, we undertook this study to find out the bacteriological profile and antibiotic sensitivity pattern of neonatal septicemia in the neonatal Intensive Care Unit. Blood cultures were performed for all clinically suspected neonatal septicemia cases for 1-year. Identification of all pathogenic isolates was followed by antibiotic sensitivity testing. We did blood cultures for 450 neonates and 42% were culture positive. Early onset sepsis were 92 (49%) and 96 (51%) were late onset sepsis. Gram-positive isolates were 60% and 40% were Gram-negative. Staphylococcus aureus (40%), coagulase negative Staphylococcus species (16%), non-fermenter group of organisms (NFGOs) (15%), and Klebsiella pneumoniae (10%) were the main isolates. Nasal cannula 101 (54%), birth asphyxia 91 (48%), and prematurity 73 (38%) were the prominent risk factors associated with septicemia. Gram-positive organisms were highly resistant to penicillin (87%) whereas Gram-negative isolates showed high resistance to third generation cephalosporins (53-89%) and aminoglycosides (50-67%). The S. aureus isolates were methicillin-resistant in 41% whereas extended spectrum beta lactamase production was seen in 48% Gram-negative isolates. Our study highlights the recent emergence of Gram-positive organisms as predominant cause of neonatal septicemia in this part of Sub-Himalayan region, along with the review of literature which shows similar results from North India and rest of the world too. Though Gram-negative bacteria still remain the main cause of mortality in neonatal septicemia, we want to dispel the common notion among practitioners that they are the predominant isolates in neonatal septicemia.

    Hepatitis A virus usually causes acute viral hepatitis (AVH) in the paediatric age group with a recent shift in age distribution and disease manifestations like acute liver failure (ALF). This has been attributed to mutations in 5'non-translated region (5'NTR) which affects the viral multiplication. The present study was aimed to carry out the molecular detection and phylogenetic analysis of hepatitis A virus strains circulating in north western India. Serum samples from in patients and those attending out patient department of Pediatric Gastroenterology in a tertiary care hospital in north India during 2007-2011 with clinically suspected AVH were tested for anti-hepatitis A virus (HAV) IgM antibodies. Acute phase serum samples were subjected to nested PCR targeting the 5'NTR region followed by sequencing of the representative strains. A total of 1334 samples were tested, 290 (21.7%) were positive for anti-HAV IgM antibody. Of these, 78 serum samples (< 7 days old) were subjected to PCR and 47.4% (37/78) samples showed the presence of HAV RNA. Children < 15 yr of age accounted for majority (94%) of cases with highest seropositivity during rainy season. Sequencing of 15 representative strains was carried out and the circulating genotype was found to be III A. The nucleotide sequences showed high homology among the strains with a variation ranging from 0.1-1 per cent over the years. An important substitution of G to A at 324 position was shown by both AVH and ALF strains. The cumulative substitution in AVH strains Vs ALF strains as compared to GBM, Indian and prototype strain in the 200-500 region of 5' NTR was comparable. Our results showed hepatitis A still a disease of children with III A as a circulating genotype in this region. The mutations at 5'NTR region warrant further analysis as these affect the structure of internal ribosomal entry site which is important for viral replication.

    Background: The metabolic syndrome (MS) (syndrome X, insulin resistance syndrome) is a constellation of metabolic abnormalities and a complex predisease state that predicts future development of type 2 diabetes mellitus and cardiovascular disease. Menopausal transition and postmenopausal state are considered as a vulnerable period for developing MS, and this increased risk has been attributed to decreasing estrogen levels with an increasing risk of insulin resistance following menopause. Aims and Objectives: This study aimed to determine the prevalence of MS and its components in pre- and post-menopausal women from North India. Methodology: This is a cross-sectional study of 350 women in the age group of 45–55 years attending gynecology clinic in a tertiary center of North India. Details of sociodemographic data, menopausal history, reproductive, and medical profile were obtained. Then, waist circumference, body mass index (BMI), and blood pressure were recorded. A venous blood sample was collected for fasting blood glucose, triglycerides, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. MS was defined according to the modified National Cholesterol Education Program Adult Treatment Panel III criteria. Results: The mean age was 49.09 ± 2.2 years in premenopausal and 49.54 ± 2.8 years in postmenopausal women. The prevalence of MS in the study group was 62.6%. Occurrence of MS was higher in older and obese women. Abnormal waist circumference was the most prevalent component (87%) of MS and in terms of odd ratio, correlation was highest for BMI followed by total cholesterol and waist-hip ratio. Conclusion: We should target obesity and deranged lipid profile by bringing out changes in lifestyle and dietary habits to decrease the higher prevalence of MS and the risk of cardiovascular diseases.

    To demonstrate the association of socio-economic status with prevalence of coronary artery disease and coronary risk factors. Cross-sectional survey in two randomly selected villages in the Moradabad district in North India. One thousand seven hundred and sixty-seven subjects (894 males and 875 females; 25-64 years of age) were randomly selected from two villages. They were divided into social classes 1 to 4, according to education, occupation, housing conditions, ownership of land, ownership of consumer durables and per capita income. The survey was based on questionnaires administered by dietitians and physicians, physical examination and electrocardiography. Social classes 1 and 2 were mainly high and middle socio-economic groups and 3 and 4 low income groups. The prevalence of coronary artery disease was significantly higher among classes 1 and 2 in both sexes, and there was a higher prevalence of hypercholesterolaemia, hypertension, and sedentary lifestyle. This population also showed a significant association with higher serum cholesterol, body mass index, triglycerides and blood pressures. Logistic regression analysis with adjustment for age showed that social class positively related to coronary disease (odds ratio: men 0.83, women 0.61), hypercholesterolaemia (men 0.85, women 0.87), hypertension (men 0.89, women 0.87), body mass index (men 0.91, women 0.93) and smoking in men (0.68). Smoking and sedentary lifestyle were not associated with social class in women. The association between coronary artery disease and social class abated after adjustment for smoking, sedentary lifestyle, body mass index and blood pressure (odds ratio: men 0.96, women 0.81). Subjects in social classes 1 and 2 in rural North India have a higher prevalence of coronary artery disease and of the coronary risk factors hypercholesterolaemia, hypertension, higher body mass index and sedentary lifestyle. The overall prevalence of coronary artery disease was 3.3%.

    The compositional zoning of a garnet population contained within a garnet-grade metapelitic schist from the Lesser Himalayan Sequence of Sikkim (India) provides insight into the rates and kinetic controls of metamorphism, and the extent of chemical equilibration during porphyroblast crystallisation in the sample. Compositional profiles across centrally sectioned garnet crystals representative of the observed crystal size distribution indicate a strong correlation between garnet crystal size and core composition with respect to major end-member components. Systematic steepening of compositional gradients observed from large to small grains is interpreted to reflect a progressive decrease in the growth rate of relatively late-nucleated garnet as a result of an increase in interfacial energies during progressive crystallisation. Numerical simulation of garnet nucleation and growth using an equilibrium approach accounting for chemical fractionation associated with garnet crystallisation reproduces both the observed crystal size distribution and the chemical zoning of the entire garnet population. Simulation of multicomponent intracrystalline diffusion within the population indicates rapid heating along the pressure-temperature path, in excess of 100°C Myr^{-1}. Radial garnet growth is correspondingly rapid, with minimum rates of 1.4 mm Myr^{-1}. As a consequence of such rapid crystallisation, the sample analysed in this study provides a close to primary record of the integrated history of garnet nucleation and growth. Our model suggests that nucleation of garnet occurred continuously between incipient garnet crystallisation at ˜520°C, 4.5 kbar and peak metamorphic conditions at ˜565°C, 5.6 kbar. The good fit between the observed and predicted garnet growth zoning suggests that the departure from equilibrium associated with garnet nucleation and growth was negligible, despite the particularly fast rates of metamorphic heating. Consequently, rates of major element

    The biological affinities of semi-nomadic, early to mid-Holocene foragers of the mid-Ganga Plain, North India are undetermined, yet understanding their place in the population history of South Asia is important. Non-metric tooth trait frequencies are reported for three broadly contemporary, bio-culturally similar, and geographically proximate samples, collectively known as Mesolithic Lake Culture (MLC). The Arizona State University - Dental Anthropology System was used to score 43 tooth-trait combinations (23 maxillary; 21 mandibular). Non-metric trait frequencies are used to determine biological affinities of MLC to a global sample of living populations and to prehistoric and living groups of South Asia. The MLC dental pattern includes lightly sculpted upper incisors in which labial curvature, lingual shoveling, and tuberculum dentale exhibit low grades of expression and low-moderate frequencies. First molars have full-sized hypocones with slight reduction in M2 and M3. Accessory cusps are infrequent and small. Mandibular teeth are morphologically simple and retain conservative attributes. Incisors and canines exhibit weak shoveling. Molar accessory cusps are infrequent, though C-6 attains moderate grades in M3. The molar series (M1:M2:M3) has an Y:X:X groove pattern and 5:4:4 cusp number. Upper M3 agenesis (5%) is less common than lower M3 agenesis (10.0%). Smith's Mean Measure of Divergence (MMD) and Ward's minimum variance cluster methods are used to assess inter-group bio-distance in global and regional South Asian settings. In the global comparison, multi-dimensionally scaled MMD values reveal three groups: African, Asian, and a third group composed of MLC, prehistoric South Asians, and European samples. Within South Asia, MMD and cluster analysis find MLC's closest affinities to the Chenchu, a living tribal group of Andhra Pradesh. This result contradicts earlier assertions based on osteological assessment that descendants of Mesolithic foragers of North

    Background With the commitment of the national government to provide universal healthcare at cheap and affordable prices in India, public healthcare services are being strengthened in India. However, there is dearth of cost data for provision of health services through public system like primary & community health centres. In this study, we aim to bridge this gap in evidence by assessing the total annual and per capita cost of delivering the package of health services at PHC and CHC level. Secondly, we determined the per capita cost of delivering specific health services like cost per antenatal care visit, per institutional delivery, per outpatient consultation, per bed-day hospitalization etc. Methods We undertook economic costing of fourteen public health facilities (seven PHCs and CHCs each) in three North-Indian states viz., Haryana, Himachal Pradesh and Punjab. Bottom-up costing method was adopted for collection of data on all resources spent on delivery of health services in selected health facilities. Analysis was undertaken using a health system perspective. The joint costs like human resource, capital, and equipment were apportioned as per the time value spent on a particular service. Capital costs were discounted and annualized over the estimated life of the item. Mean annual costs and unit costs were estimated along with their 95% confidence intervals using bootstrap methodology. Results The overall annual cost of delivering services through public sector primary and community health facilities in three states of north India were INR 8.8 million (95% CI: 7,365,630–10,294,065) and INR 26.9 million (95% CI: 22,225,159.3–32,290,099.6), respectively. Human resources accounted for more than 50% of the overall costs at both the level of PHCs and CHCs. Per capita per year costs for provision of complete package of preventive, curative and promotive services at PHC and CHC were INR 170.8 (95% CI: 131.6–208.3) and INR162.1 (95% CI: 112–219

    In this article, I describe a study that generates a substantive theory of healing from the conflict experienced by second-generation emigrants from India living in North America. Qualitative methodology, specifically, the Grounded Theory method of data analysis and theory building, was used. Literature elucidating the differences between North American and Indian cultural values was used as a basis for exploration. Results suggest that cultural conflict stems from areas such as education and success, pressure from parents to maintain traditional cultural values, family bonds and lack of boundaries, parental control and abuse, and dating and marriage. The results of the conflict are discussed by participants in terms of loneliness and pain, lying, rebellion, or acceptance of cultural values. The factors that mediate the conflict and that determine the degree to which participants rebel or accept the cultural values seem to be linked to the approval and acceptance individuals received from their family or community and their level of self-esteem. Finally, I discuss how individuals can heal from the conflict. Methods of healing include communication with and education for parents, therapy in the areas of anger, resentment, and self-esteem, and developing an alternative support system, which may include other second-generation individuals.

    A sediment core from Lonar Lake in central India covers the complete Holocene and was used to reconstruct the monsoon history of the core SW-monsoon region. We compare C/N ratios, stable carbon and nitrogen isotopes, grain size, as well as amino acid derived degradation proxies with climatically sensitive proxies of other records from South Asia and the North Atlantic region. The comparison reveals some more or less contemporaneous climate shifts. At Lonar Lake, a general long term climate transition from wet conditions during the early Holocene to drier conditions during the late Holocene, delineating the insolation curve, can be reconstructed. Several phases of shorter term climate alteration that superimpose the general climate trend correlate with cold phases in the North Atlantic region. The most pronounced climate deteriorations indicated by our data occurred between 6.2 - 5.2, 4.65 - 3.9, and 2.05 - 0.55 cal ka BP. The strong dry phase between 4.65 - 3.9 cal ka BP at Lonar Lake corroborates the hypothesis that severe climate deterioration contributed to the decline of the Indus Civilisation about 3.9 ka BP.

    We aimed to identify the role of vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein (MCP-1) as a serum biomarker of symptomatic carotid atherosclerotic plaque in North Indian population. Individuals with symptomatic carotid atherosclerotic plaque have high risk of ischemic stroke. Previous studies from western countries have shown an association between VEGF and MCP-1 levels and the incidence of ischemic stroke. In this study, venous blood from 110 human subjects was collected, 57 blood samples of which were obtained from patients with carotid plaques, 38 neurological controls without carotid plaques, and another 15 healthy controls who had no history of serious illness. Serum VEGF and MCP-1 levels were measured using commercially available enzyme-linked immunosorbent assay. We also correlated the data clinically and carried out risk factor analysis based on the detailed questionnaire obtained from each patient. For risk factor analysis, a total of 70 symptomatic carotid plaque cases and equal number of age and sex matched healthy controls were analyzed. We found that serum VEGF levels in carotid plaque patients did not show any significant change when compared to either of the controls. Similarly, there was no significant upregulation of MCP-1 in the serum of these patients. The risk factor analysis revealed that hypertension, diabetes, and physical inactivity were the main correlates of carotid atherosclerosis (p < 0.05). Prevalence of patients was higher residing in urban areas as compared to rural region. We also found that patients coming from mountain region were relatively less vulnerable to cerebral atherosclerosis as compared to the ones residing at non mountain region. On the contrary, smoking, obesity, dyslipidemia, alcohol consumption, and tobacco chewing were not observed as the determinants of carotid atherosclerosis risk in North India (p > 0.05). We conclude that the pathogenesis of carotid plaques may progress

    Rotavirus G1 strains are the predominant cause of diarrhoea in children. Universally common rotavirus vaccines (Rotarix and RotaTeq) include G1 as the immunological component. India has recently introduced rotavirus vaccine in Universal Immunization Programme. Therefore, in the present study, VP7 gene of rotavirus G1 strains circulating in Himachal Pradesh, India is analysed to study their phylogenetic characteristics, and further comparative analysis was performed for assessment of their divergence from the vaccine strains. The rotavirus strains (JU-SOL-5, JU-SOL-58, JU-SOL-77, JU-SOL-173 and JU-SHI-14) analysed in the study were isolated from the faeces of diarrhoeic children during active surveillance for rotaviruses. The Himachal strains clustered together in G1-Lineage 1 in the phylogenetic analysis. All five isolates showed 96.4-98.8 % similarity with the other G1-Lineage 1 strains at amino acid level. However, none of them clustered in the pre-defined sublineages within lineage 1. Interestingly, all the strains were distantly related to the vaccine strains having 93.9-94.5 and 91.9-92.6 % similarities at amino acid level with Rotarix and RotaTeq strains, respectively. The comparative sequence and structural analysis of the Himachal strains with vaccine strains revealed differences in amino acids in epitope region of the protein especially at the antibody neutralization sites. The study highlights variations between the G1 strains from Himachal Pradesh, India and Rotarix and RotaTeq vaccine strains. These differences might have an impact on the neutralization efficiency of vaccine and subsequently on vaccine efficacy. This underscores further investigation to study intragenotype antigenic variability and also impact of viral evolution on vaccine effectiveness.

    Abstract Chordodes mizoramensis, a new species of freshwater gordiid horsehair worm, is described from Mizoram, NE India on the basis of scanning electron microscopic and morphometric studies. The new species can be distinguished from its congeners in that the apical filaments of the crowned areoles are branched several times, a pattern that has not been observed in other species. An additional distinguishing character is that it has more bulging areoles, which are distributed among simple areoles alone or in groups, do not form clear patterns. PMID:21594136

    Aim: To identify the suitable roofing pattern for dairy cattle in North East Zone of Tamil Nadu, India, based on micro climatic conditions. Materials and Methods: Initially, survey was conducted to identify and categorize the major housing patterns existing in the region for further detailed investigation. In total, 30 farmers/farms consisting of five housing types with six replicates were selected. Temperature and temperature humidity index (THI) were recorded using the maximum-minimum thermometer and digital thermo-hygrometers. The study was conducted for 1 year covering four seasons namely South West monsoon (June-August), North East monsoon (September-November), cold season (December-February), and summer season (April-May). The data were statistically analyzed using statistical package SPSS 17. Results: Animal shelters with cement sheets recorded the highest temperature (26.71±1.13°C) and THI (77.23±1.76) at 8.00 am, whereas the lowest temperature (24.83±1.17°C) and THI (74.54±1.72) were recorded in the thatched shed. There was significant difference (p<0.01) in temperature and THI at 8.00 am during South West monsoon and North East monsoon seasons between the housing types. During cold and summer seasons, there was no significant difference (p≥0.05) in the environmental variables among various shelter systems. Conclusion: Thatched housing is found to be the suitable one with respect to the climatic variables, followed by tile roof and metal roof. The cement sheet roofed housing is found to be the most unsuitable one in the region for dairy cattle. PMID:28246440

    The aim of the study was to assess the prevalence of dental fluorosis, dental caries, and associated risk factors in the school children of district Fatehgarh Sahib, Punjab, India, using a cross-sectional study design. Oral health status of children aged between 8 and 15 years was assessed using World Health Organization (WHO) 2013 criteria. Dental fluorosis was assessed using Dean's index, and dental caries were recorded using decayed, missing, filled/decayed, extracted, filled (DMF/def) indices. Four hundred school children were examined, of which 207 were in the 8-11-year-old group and 193 were in the 12-15-year-old group. The overall prevalence of dental fluorosis was 4.1%, which might be linked to a high concentration of fluoride in drinking water at certain locations of rural Punjab. The prevalence of dental caries was 36.5% with a mean DMF score of 0.3 and def score of 0.6. Risk factors for dental caries include oral hygiene behavior and sugar consumption patterns. The study highlights the need to increase awareness about the oral health and hygiene among the school children in India.

    The issues of providing quality blood products and maintaining donor safety are primary aims of blood transfusion services. A comprehensive quality system should be in place to fulfill these aims, which can be attained through strict adherence to the established standard operating procedures (SOPs). The Drugs and Cosmetics Act of India, which controls the licensing of blood transfusion services, does not provide clear guidelines regarding plateletpheresis procedure. We, therefore, established our own SOP and operational flow chart for plateletpheresis that can be easily followed by other centers in India. A total of 100 plateletpheresis procedures performed using two cell separators (CS3000 Baxter Healthcare, Round Lake, IL; MCS3p, Haemonetics Corporation, Braintree, MA) were evaluated following our established SOP. The mean platelet yield in CS3000 was 2.9 +/- 0.84 x 10(11) and in MCS3p it was 2.88 +/- 0.75 x 10(11)per unit. However, only 4-7% of SDPs showed WBC levels <5 x 10(6) due to lack of appropriate methods to quantitate residual WBC counts. Six of 100 donors complained of hypocalcemic symptoms. The operational flow chart designed in this study was found to be simple and easy to adapt by blood transfusion services in this country.

    Background & objectives: Elevated blood pressure (BP) in the young predicts serious cardiovascular events in the adults. High prevalence of adult hypertension reported from Assam, North East (NE) India may be linked with elevated blood pressure in the childhood. The present study was an attempt to describe the distribution of BP and correlates of hypertension in children aged 5-14 yr. Methods: A total of 10,003 school children from 99 schools of Dibrugarh district, Assam, NE India, were surveyed by stratified random cluster method. Blood pressure, demographic and anthropometric information were recorded. Blood pressure was categorized in to normal, prehypertension, stage I and stage II hypertension. Results: Girls had significantly higher (104.2 ± 12.0 vs. 103.2 ± 11.6 mm Hg, P<0.001) mean systolic blood pressure (SBP) than boys. Both SBP and diastolic blood pressure (DBP) revealed significant correlation with age, height, weight and BMI in overall and in gender specific analysis. Hypertension was found in 7.6 per cent school children (Boys: 7.3%, Girls: 7.8%). In multivariable analysis older age (OR 3.3, 95% CI: 2.82-3.91), children from tea garden community (OR 1.3, 95% CI: 1.08-1.55) and other community (OR 1.4, 95% CI: 1.18-1.73) and overweight (OR 1.5, 95% CI: 1.1-2.1) were independently associated with hypertension. Interpretation & conclusions: Mean blood pressure in the young school children of 5-14 yr was high. A programme comprising screening, early detection and health promotion through school health programmes may help prevent future complications of hypertension. PMID:26458345

Methods: Retrospective review of case records of HIV-TB co-infected patients attending the antiretroviral therapy (ART) clinic in a tertiary care centre in north India was done. Results: Of the 1754 patients included in the study, 583 (33.2%) were diagnosed with active TB and 466 (79.9%) of them had CD4 count less than 200/μl at diagnosis. Extrapulmonary TB was diagnosed in 372 (63.8%) patients [76 (20.4%) had disseminated TB], and pulmonary TB in 211 (36.2%) patients. Favourable outcome (cure and completed treatment) was observed in 332 (77%) patients. Unfavourable outcome included default (8.1%), treatment failure (1.6%), and death (13.2%). At 1-year post-treatment follow up, 12 (3.6%) patients had disease relapse. CD4 count of less than 200/μl at diagnosis [OR-2.32, CI (1.06-5.09)], and retreatment cases [OR-2.91, CI (1.22-6.89)] were independent predictors of unfavourable outcome. Interpretation & conclusions: There is an urgent need to strengthen the information, education, communication activities and expand the ART services to meet the requirement of early testing and treatment initiation in patients co-infected with HIV-TB. The findings highlight the need for performing drug susceptibility testing (DST) for patients starting retreatment regimen to improve treatment outcome. PMID:24604050

    The assessment of Citrus tristeza virus incidence in mandarin of Sikkim, involving sampling techniques, was estimated by DAS-ELISA. Mandarin orchards had high CTV incidence (46.32%), however, differential prevalence with regard to age of plant and location was observed. The CTV prevalence was relatively high in older orchards (51.01%) than that of younger ones (40.80%). Under all the plant age groups, south district had the highest CTV incidence (52.50%) and east district had the lowest (37.71%). The spatial distribution of CTV in plants indicates high concentration in twig followed by leaf tissue, however, stem had relatively less concentration. High aphid infestation was observed in all mandarin growing groves with the maximum in south district and minimum in east district. Taxoptera citricida was the predominating aphid species followed by T. aurantii, however, Aphis spp population was significantly less. Aphid infestation and CTV prevalence were positively and significantly correlated.

    Climatic changes alter the climate system, leading to a decrease of glacier mass volumes and swelling glacial lakes. This study provides a new inventory of glacial and high-altitude lakes for Sikkim, Eastern Himalaya, and evaluates the susceptibility of lakes to Glacial Lake Outburst Flood (GLOF). By using satellite data of high spatial resolution (5 m), we obtain 1104 glacial and high-altitude lakes with total area 30.498 km2, of which 472 have an area > 0.01 km2. Applying pre-defined GLOF susceptibility criteria on these 472 lakes yields 21 lakes susceptible to GLOF, which all increased in area from 1972-2015. Using Analytic Hierarchy Processes (AHP), the pairwise comparison matrix further reveals that 5 of these glacial lakes have low, 14 have medium and 2 have high GLOF susceptibility. Especially these 16 glacial lakes with high and medium GLOF susceptibility may threaten downstream communities and infrastructure and need further attention.

    Dermatoglyphic print comparisons can be utilized to establish personal identification in forensic cases. The northern part of the state of West Bengal, India, is the home to many ethnic populations. Two such populations are the Rajbanshi and the Mech. Palm prints were collected from 192 adult Rajbanshi (105 men and 87 women) and 100 adult Mech (50 men and 50 women) individuals for print comparison using the standard ink and roll print method. The dermatoglyphic variables studied were mainline formulae, termination of mainline, positional variation of axial triradii, and true pattern of hypothenar and thenar configuration area. There were differences between the Rajbanshi and Mech individuals with respect to these dermatoglyphic variables. The uses of these variables appear to be limited only to ethnic identification, not personal identification. The present investigation further highlights the racial affinity, sex, and bilateral differences among Rajbanshi individuals using dermatoglyphic palmar variables.

    Background: Rural areas pose challenges for motivating villagers to donate blood. We organized a blood donation camp in a rural setting by engaging multiple stakeholders. We examined the factors that influenced blood donation. Methods: Local level stakeholders were involved in planning of the camp. Mobilization of donors was attempted through intensive awareness generation activities utilizing multiple channels. A list of willing blood donors was prepared. Results: Out of 152 willing donors, 88 reported to donation camp, and after screening, 67 donated the blood. Most of the willing donors were males (89.8%), and the mean standard deviation age was 31.9 (9.4) years. Deferral rate was 23.8%. Involvement of local stakeholders can result in creating a pool of donors in rural area which can mitigate the existing gap between demand and supply of blood in India. PMID:28217590

    In India, Janani Shishu Suraksha Karyakaram (JSSK) was launched in the year 2011 to assure cashless institutional delivery to pregnant women, including free transport and diet. To assess the impact of JSSK on institutional delivery. A record review was done at the primary health care facility in Faridabad district of Haryana from August 2010 to March 2013. Focus group discussion/ informal interviews were carried out to get an insight about various factors determining use / non-use of health facilities for delivery. Institutional delivery increased by almost 2.7 times (197 Vs 537) after launch of JSSK (p < 0.001). For institutional deliveries, the most important facilitator as well as barrier was identified as ambulance service under JSSK and pressure by elders in the family respectively. JSSK scheme had a positive impact on institutional deliveries. It should be supported with targeted intervention designed to facilitate appropriate decision-making at family level in order to address barriers to institutional delivery.

    Since a very long time, a significant number of patients have been seeking treatment at Complementary and Alternative Medicine health facilities, but the disease burden at these facilities has never been assessed and documented. Present cross-sectional study was carried out at Ayurvedic tertiary care hospital to document and to assess the rationale of disease reporting at Ayurvedic institutions of the northern state of India from January 2011 to October 2011. Almost half of the patients’ morbidities were not classified at all into any of the disease categories. The common reported morbidities at study hospital were: Respiratory (10.5%), neuromuscular (9.5%), digestive (9.2%) and circulatory (9.1%) disorders. As the majority of diseases were unclassified, so mainstreaming of the effective disease surveillance would be required to understand the morbidity pattern and successful treatment practices at health facilities.

    Falls have been identified as a leading cause of injury-related morbidity and mortality in India. However, very little is known about the context and characteristics of such falls. The aim of this study was to describe the context and characteristics of fall related injuries in patients admitted to hospital for fall injury. Medical records of patients presenting at the Emergency Department of the Nehru Hospital, Chandigarh, India between March 2008 and February 2009, were reviewed by trained investigators. All injury cases were identified and fall related injury cases were assigned an ICD 10, Chapter XX, External causes of morbidity and mortality code. A review of medical records was conducted to determine the context, nature and site of injury associated with a fall event. Ten percent (7049) of hospital emergency presentations were due to injuries, and falls were the second leading cause (20%, 1407). Seventy-six percent of the fall related presentations were in males. More than one third (36%) of the fall related presentations occurred in those aged 0-14 years old. Falls from building or structures (35%, 499) were the leading cause for all ages except for those older than 60 years, where same level falls due to slipping, tripping and stumbling (40%, 57) were predominant. Half of all the falls resulted in head injury. Nearly 10% of patients presenting for fall related injury died. Fall related injuries are an important contributor to hospital emergency presentations, particularly falls from buildings in children, and slips and trips in older people. Given the high proportion of falls that resulted in head injury and death, there is a significant need to develop appropriate interventions to prevent such falls. Copyright © 2011 Elsevier Ltd.

    India has one of the most extensive health infrastructures- a three-tier hierarchical referral system- for the provision of effective and efficient health services to the majority of its population. In this study we have tried to evaluate the utilization of such a wide health infrastructure and the various factors affecting it. We have also tried to find the factors that motivated the patients to visit the present health facility and the key persons who motivated them to do so. Time bound cross-sectional study. Three types of referral health facilities in Lucknow District. A total of 1265 patients were interviewed during the four months of the period of survey from these three types of referral health facilities. The present study revealed that majority of the patients coming to all the three referral centres were the new patients (89%), about two-thirds of whom had come there directly. Overall, only one tenth of the patients attending the secondary and tertiary level public health facilities were referred by someone. Most of the indirect patients had self referred themselves. About eight and nine percent of the indirect and referred patients could reach the present site of treatment only after more than two years of rummaging and about 13% and 11% had spent more than ten thousand rupees respectively, which in some cases even amounted to lakh rupees. The utilization of the referral system of the health care delivery in India needs to be augmented. Before planning future reforms such as decentralization, incorporation of the Indian system of Medicine, and other steps we need to develop mechanisms to see that the plans are materialized.

    Helminthozoonoses are being considered as a research priority in India and many other tropical and subtropical countries. Taenia solium and Trichinella spiralis are emerging public health and food safety issues in the country and the developing world. The asymptomatic Ta. solium carriers act as important risk for neurocysticercosis, leading to adult onset epilepsy in the country. Human toxocariasis is another common zoonosis which occurs due to larvae of Toxocara canis or T. cati. The current study was planned to obtain baseline seropositivity data for Ta. solium, To. canis and Tr. spiralis antibodies among selected populations in Punjab province of northern India. In the present study, 122 human subjects belonging to selected occupations viz. farmers and veterinary practitioners were screened using the RIDASCREEN(®) Ta. solium IgG, RIDASCREEN(®) Toxocara IgG and RIDASCREEN(®) Trichinella IgG enzyme immunoassays for the qualitative determination of IgG antibodies against Ta. solium, Tr. spiralis and To. canis, respectively in human serum. The seropositivity of To. canis, Tr. spiralis and Ta. solium infections were found to be 22.13, 5.73 and 11.47 %, respectively in human serum samples. The relative risk of being infected for To. canis, Tr. spiralis and Ta. solium infections was found to be 1.91 (95 % CI 0.786-4.669), 2.61 (95 % CI 0.3258-20.94) and 1.596 (95 % CI 0.427-5.3893) times high respectively in farmers when compared to veterinary practitioners. The present study indicates that exposure to To. canis and Ta. solium is not uncommon among farmers and veterinary practitioners in this part of the country. These results provided evidence of Tr. spiralis among selected human populations in the country and demand more research related to trichinellosis in their respective animal and human hosts.

    Rodents affect the post-dispersal fate of seeds by acting either as on-site seed predators or as secondary dispersers when they scatter-hoard seeds. The tropical forests of north-east India harbour a high diversity of little-studied terrestrial murid and hystricid rodents. We examined the role played by these rodents in determining the seed fates of tropical evergreen tree species in a forest site in north-east India. We selected ten tree species (3 mammal-dispersed and 7 bird-dispersed) that varied in seed size and followed the fates of 10,777 tagged seeds. We used camera traps to determine the identity of rodent visitors, visitation rates and their seed-handling behavior. Seeds of all tree species were handled by at least one rodent taxon. Overall rates of seed removal (44.5%) were much higher than direct on-site seed predation (9.9%), but seed-handling behavior differed between the terrestrial rodent groups: two species of murid rodents removed and cached seeds, and two species of porcupines were on-site seed predators. In addition, a true cricket, Brachytrupes sp., cached seeds of three species underground. We found 309 caches formed by the rodents and the cricket; most were single-seeded (79%) and seeds were moved up to 19 m. Over 40% of seeds were re-cached from primary cache locations, while about 12% germinated in the primary caches. Seed removal rates varied widely amongst tree species, from 3% in Beilschmiedia assamica to 97% in Actinodaphne obovata. Seed predation was observed in nine species. Chisocheton cumingianus (57%) and Prunus ceylanica (25%) had moderate levels of seed predation while the remaining species had less than 10% seed predation. We hypothesized that seed traits that provide information on resource quantity would influence rodent choice of a seed, while traits that determine resource accessibility would influence whether seeds are removed or eaten. Removal rates significantly decreased (p < 0.001) while predation rates increased (p = 0

    The aim of this study is to report the regional distribution of Cryptococcus. gattii and Cryptococcus. neoformans in decayed wood inside trunk hollows of Syzygium cumini trees (Java plum, Indian black berry) investigated in Amritsar (Panjab), Meerut Cantt. and Bulandshahr (Uttar Pradesh) and Delhi, in north-western India. Two hundred and seventeen wood samples collected from 74 S. cumini trees were investigated. This includes 7 known positive S. cumini trees in Delhi subjected to a mycological surveillance for perennial colonization by C. gattii and C. neoformans. Cryptococcus gattii showed the highest prevalence (89%) in S. cumini trees in Delhi, followed by 27%, 12.5% and 9% prevalence in Bulandshahr, Amritsar City and Meerut Cantt., respectively. In contrast, C. neoformans had the highest prevalence (54%) in Amritsar, followed by 44% in Delhi, 9% in Bulandshahr and 0% in Meerut Cantt. Furthermore, 44% of the S. cumini trees in Delhi, 9% in Bulandshahr and 8% in Amritsar were concomitantly colonized by both C. gattii and C. neoformans. A mycological surveillance over 4.8-5.2 years of 7 selected S. cumini trees in Delhi revealed perennial colonization by both the Cryptococcus species. In addition, air samples taken close to the decayed trunk hollows of 4 of the perennially colonized S. cumini trees contained strains of the C. neoformans species complex. Of a random sample of 48 isolates serotyped, 26 (54%) were C. neoformans, serotype A, and 22 (46%) C. gattii, serotype B. Determination of mating type alleles was done in 44 of the isolates, comprising 31 of C. neoformans, serotype A and 13 of C.gattii, serotype B. All of them proved to be mating type alpha (MATalpha). The data on high prevalence, fungal population density, perennial colonization and aerial isolations indicate that decayed wood in trunk hollows of S. cumini trees is to-date the main well documented primary environmental niche of C. gattii and C. neoformans in north-western India.

    Background & objectives: Hepatitis A virus usually causes acute viral hepatitis (AVH) in the paediatric age group with a recent shift in age distribution and disease manifestations like acute liver failure (ALF). This has been attributed to mutations in 5’non-translated region (5’NTR) which affects the viral multiplication. The present study was aimed to carry out the molecular detection and phylogenetic analysis of hepatitis A virus strains circulating in north western India. Methods: Serum samples from in patients and those attending out patient department of Pediatric Gastroenterology in a tertiary care hospital in north India during 2007-2011 with clinically suspected AVH were tested for anti-hepatitis A virus (HAV) IgM antibodies. Acute phase serum samples were subjected to nested PCR targeting the 5’NTR region followed by sequencing of the representative strains. Results: A total of 1334 samples were tested, 290 (21.7%) were positive for anti-HAV IgM antibody. Of these, 78 serum samples (< 7 days old) were subjected to PCR and 47.4% (37/78) samples showed the presence of HAV RNA. Children < 15 yr of age accounted for majority (94%) of cases with highest seropositivity during rainy season. Sequencing of 15 representative strains was carried out and the circulating genotype was found to be III A. The nucleotide sequences showed high homology among the strains with a variation ranging from 0.1-1 per cent over the years. An important substitution of G to A at 324 position was shown by both AVH and ALF strains. The cumulative substitution in AVH strains Vs ALF strains as compared to GBM, Indian and prototype strain in the 200-500 region of 5’ NTR was comparable. Interpretation & conclusion: Our results showed hepatitis A still a disease of children with III A as a circulating genotype in this region. The mutations at 5’NTR region warrant further analysis as these affect the structure of internal ribosomal entry site which is important for viral

    2009-01-01

    Background This paper studies the determinants of utilization of health care services, especially for treatment of febrile illness in the malaria endemic area of north-east India. Methods An area served by two districts of Upper Assam representing people living in malaria endemic area was selected for household survey. A sample of 1,989 households, in which at least one member of household suffered from febrile illness during last three months and received treatment from health service providers, were selected randomly and interviewed by using the structured questionnaire. The individual characteristics of patients including social indicators, area of residence and distance of health service centers has been used to discriminate or group the patients with respect to their initial and final choice of service providers. Results Of 1,989 surveyed households, initial choice of treatment-seeking for febrile illness was self-medication (17.8%), traditional healer (Vaidya)(39.2%), government (29.3%) and private (13.7%) health services. Multinomial logistic regression (MLR) analysis exhibits the influence of occupation, area of residence and ethnicity on choice of health service providers. The traditional system of medicine was commonly used by the people living in remote areas compared with towns. As all the febrile cases finally received treatment either from government or private health service providers, the odds (Multivariate Rate Ratio) was almost three-times higher in favour of government services for lower households income people compared to private. Conclusion The study indicates the popular use of self-medication and traditional system especially in remote areas, which may be the main cause of delay in diagnosis of malaria. The malaria training given to the paramedical staff to assist the health care delivery needs to be intensified and expanded in north-east India. The people who are economically poor and living in remote areas mainly visit the government

    Hill rices (Oryza sativa L.) are direct seeded rices grown on hill slopes of different gradients. These landraces have evolved under rainfed and harsh environmental conditions and may possess genes governing adaptation traits such as tolerance to cold and moisture stress. In this study, 64 hill rice landraces were collected from the state of Arunachal Pradesh of North-Eastern region of India, and assessed by agro-morphological variability and microsatellite markers polymorphism. Our aim was to use phenotypic and genetic diversity data to understand the basis of farmers' classification of hill rice landraces into two groups: umte and tening. Another goal was to understand the genetic differentiation of hill rices into Indica or japonica subspecies. According to farmers' classification, hill rices were categorized into two groups: umte (large-grained, late maturing) and tening (small-grained, early maturing). We did not find significant difference in days to 50 % flowering between the groups. Principal component analysis revealed that two groups can be distinguished on the basis of kernel length-to-width ration (KLW), kernel length (KL), grain length (GrL), grain length-to-width ration (GrLW) and plant height (Ht). Stepwise canonical discriminant analysis identified KL and Ht as the main discriminatory characters between the cultivar groups. Genetic diversity analysis with 35 SSR markers revealed considerable genetic diversity in the hill rice germplasm (gene diversity: 0.66; polymorphism information content: 0.62). Pair-wise allelic difference between umte and tening groups was not statistically significant. The model-based population structure analysis showed that the hill rices were clustered into two broad groups corresponding to Indica and Japonica. The geographic distribution and cultivars grouping of hill rices were not congruent in genetic clusters. Both distance- and model-based approaches indicated that the hill rices were predominantly japonica or

    In the Hazara arc region of northern Pakistan, some of the active basements structures buried below a thick, detached sedimentary layer are inferred from the distribution of lineaments and the drainage patterns, as viewed in Landsat satellite imagery and from river profiles. A prominent set of NW-trending lineaments seen on satellite imagery, coincides approximately with the southwest or updip side of the Indus—Kohistan seismic zone (IKSZ) —the most active basement structure of the region, even though this structure is buried beneath and decoupled from a 12 km thick sedimentary layer. The IKSZ has been interpreted as an extension of the Himalayan Basement Thrust, and is also associated with a prominent topographic "step". Knickpoints on major rivers in the region lie on or north of the IKSZ. All Indus River tributaries, examined north of the IKSZ, show prominent knickpoints, while two tributaries draining south of the IKSZ have no knickpoints. These results suggest ongoing uplift above and north of the IKSZ, and are consistent with the tectonic model obtained from the seismic data. Another prominent lineament set is detected along the north—south section of the Indus River. This set is probably related to the Indus River horst—anticline and associated reentrant. One of the two highest lineament concentrations occurs at the intersection between the NW-trending IKSZ lineament and the N-trending Indus River lineament. The other is along the west bank of the Indus Valley, 25 km north of Tarbela Dam. A topographic ridge (Swabi—Nowshera ridge) appears to be forming along the west side of the Indus River, in the Peshawar Basin. The rising ridge is ponding the Kabul River upstream of Nowshera, where the drainage is braided.

    Injuries are a serious cause of mortality and morbidity worldwide, with trauma being the leading cause of death in the first four decades of life. By contrast with the declining rates of injury seen in high-income countries, low-income and middle-income countries (LMICs) are experiencing an increase in injury rates, largely due to increased motorisation in these countries. In this study, we report the out-of-pocket expenditure and financial risk protection from trauma care in a tertiary care hospital of India. Patients who were admitted for at least one night in a tertiary care hospital of Chandigarh during a 1 month period from April 15, 2013, and May 15, 2013, were recruited. Data were collected for the type of injury, out-of-pocket expenditure, and mechanisms undertaken to cope up with the expenditure. Cases were followed up at 1 month, 2 months, and 12 months after discharge to collect information about out-of-pocket expenditure. Prevalence of catastrophic expenditure-ie, if it exceeded 30% of the patient's annual household income-and distress financing-ie, if borrowing (with or without interest) or selling of assets was used to cope with high out-of-pocket expenditure, were assessed among patients recruited. Assuming prevalence of catastrophic expenditure to be 22%, with a precision of 5·5% and 5% alpha error, the sample size was estimated to be 218. 227 patients were recruited, of whom 155 (68%) were followed up until 12 months. No significant differences were noted based on sociodemographic, injury, and hospitalisation characteristics between the patients who were followed up and those who were lost to follow-up. Average out-of-pocket expenditure per admission to hospital was US$388 (95% CI 332-441) and at 12 months after injury was US$1046 (871-1221). Mean out-of-pocket expenditure for road traffic injury cases at the time of hospitalisation was US$400 (95% CI 344-456) and for non-road traffic injury cases was US$369 (313-425). The prevalence of

    Present study was aimed to find out dimension and socio-demographic correlates of domestic violence in Assam, Sikkim and Meghalaya, Northeast India. Two districts from each state were selected at random and women aged 18-35 years from rural and urban localities were interviewed to obtain relevant information. The study included a total of 2249 participants (Rural = 1577 and Urban = 672) from Assam (650), Sikkim (1148) and Meghalaya (451). Domestic violence was recorded in 26.4% of study participants and highest in Meghalaya. Of all types, psychological violence was predominant. A number of socio-demographic factors have been identified as independent predictors for domestic violence in pooled and state specific analysis. Findings of our study may help in formulating strategies to prevent domestic violence.

    The north eastern part of Anantapur district is in the state of Andhra Pradesh, India, is significant as it is covered by varied geological formations and has different land use and irrigation practices. Though ground water is the major drinking water source, deterioration in its quality is going unchecked. In such agro-economy based rural areas, the nitrate contamination is rampant and much attention has not been drawn towards this anthropogenic pollution. In the study area ground water samples from different hydrogeological set-up have been collected during the pre and post monsoon seasons and analysed for the major ions such as Ca, Mg, Na, K, CO(3), HCO(3), Cl, SO(4), NO(3) and F. The study revealed that 65% of the samples were found to be unsuitable for drinking purposes in the pre monsoon season and 45% in the post monsoon due to excess nitrate (>45 mg/l) content in the ground water. Among the different seasons and environs, nitrate was in highest concentration in the granitic terrain and canal command areas during pre monsoon season. The nitrate was found to decrease with depth in all the hydrogeological set-ups in both the seasons. Intense agriculture practices, improper sewerage and organic waste disposal methods were observed to contribute nitrate to the shallow and moderately deep aquifers.

    This study aimed to understand how adolescents with disabilities can assume greater control over their rehabilitation and participation within a community-based rehabilitation programme in the urban slums of North India. A critical ethnographical approach using multiple qualitative and participatory data collection methods was adopted. Fieldwork was conducted from January to May 2005 and October 2006 to March 2007 with 21 adolescents with and 11 adolescents without disabilities (aged 12 to 18 years), and 10 community-based rehabilitation staff members. A conceptual framework called the 'Adolescent Group Empowerment Pyramid' was developed. Four themes informed the framework: group participation, group demonstration, group recognition and the socio-cultural environment's interaction with disability. Group empowerment, achieved through group-centred occupations, encourages adolescents to work together to address their rehabilitation challenges and agendas. Three external support factors and 10 areas for nurturing the group empowerment process also emerged. A limitation of this study is the lack of data on how the familial and local political and economic environment impact adolescents' ability to make decisions about their rehabilitation. Further research might explore group occupations and occupational recognition, and what this means for social change and the personal and collective growth of adolescents in underserviced communities.

    Secondary education among lower caste adolescent girls living in rural Karnataka, South India, is characterized by high rates of school drop-out and absenteeism. A cross-sectional baseline survey (N=2275) was conducted in 2014 as part of a cluster-randomized control trial among adolescent girls (13-14 year) and their families from marginalized communities in two districts of north Karnataka. Bivariate and multivariate logistic regression models were used. Overall, 8.7% girls reported secondary school dropout and 8.1% reported frequent absenteeism (past month). In adjusted analyses, economic factors (household poverty; girls' work-related migration), social norms and practices (child marriage; value of girls' education), and school-related factors (poor learning environment and bullying/harassment at school) were associated with an increased odds of school dropout and absenteeism. Interventions aiming to increase secondary school retention among marginalized girls may require a multi-level approach, with synergistic components that address social, structural and economic determinants of school absenteeism and dropout.

    The present study analyses the potential role of MTHFR gene polymorphism, folate supplementation and dietary pattern among the mothers of NTD neonates and controls in heterogeneous populations of North India, with the special focus on their ethnic labels. Results indicated significant increased risk for neural tube defects with respect to low folic acid supplementation and vegetarian diet in univariate and multivariate analyses. There was no significant difference in the genotypic or allelic distribution of MTHFR C677T polymorphism, however, high frequency of CT genotype, as observed, among controls suggests heterozygous advantage probably due to supplementary folate. Among the two communities, Muslim NTD mothers had higher TT genotype showing increased risk for neural tube defects (adjusted OR: 12.9; 95% CI: 1.21-136.8) and lower folic acid supplementation (adjusted OR: 3.5; 95% CI: 1.18-10.22). Whereas, marginal increased risk for NTDs with vegetarian diet was observed among Hindus. Cultural and ethnic variation in the risk factors for neural tube defects is highlighted in the study.

    The present study aims to understand the existing genetic diversity and structure of six native cattle breeds (Rathi, Tharparkar, Nagori, Mewati, Gir, and Kankrej) adapted to the north-western arid and semi-arid region of India based on microsatellite loci. Various diversity estimates, mean number of alleles (12.84); effective number of alleles (5.02); gene diversity (0.769), and observed heterozygosity (0.667) reflected the existence of substantial within-breed diversity in all the investigated cattle breeds. Mean estimates of F-statistics: F(IT) = 0.144 ± 0.023, F(IS) = 0.071 ± 0.021, and F(ST) = 0.078 ± 0.014 were significantly different from zero (P < 0.05). The interbreed relationships indicated moderate level of breed differentiation between the six cattle breeds with least differentiation between Kankrej-Mewati pair. The phylogeny structuring further supported close grouping of Kankrej and Mewati breeds. Correspondence analysis plotted Rathi, Tharparkar, and Gir individuals into three separate areas of multivariate space; whereas, Kankrej, Mewati, and Nagori cattle showed low breed specific clustering. This reflected the existence of discrete genetic structure for Tharparkar, Rathi, and Gir, the prominent dairy breeds of the region; whereas, admixture was observed for Kankrej, Mewati, and Nagori individuals.

    Context: Emergency contraception (EC) is use of drug or device to prevent pregnancy after unprotected sexual intercourse. Unlike other regular methods of contraception which are taken prior to the sexual act, EC is used after the unprotected sex. Aim: To assess the knowledge and attitude toward use of emergency contraceptives among medical students. Setting and Design: A cross-sectional questionnaire based study was conducted among all the medical students in the Government Medical College in North-West India. Subjects and Methods: A questionnaire seeking information on knowledge and attitude of undergraduate medical students was administered over a period of 4 weeks in the month of February and March 2014. Statistical Analysis: The data were entered in MS excel and expressed using percentages. Chi-square test was used as a test of statistical significance. Results: About 61.6% (247/401) of the participants were aware about the timing of use of EC. Audio visual media (76.6%; 307/401) was the most common source of information for of these medical students. Conclusions: The lack of appropriate in-depth knowledge of EC among future health care professional should alarm the medical teaching system as EC is the only method that can be used to prevent pregnancy after unprotected sex or contraceptive accident.

    Introduction: Early diagnosis and management of depression is important for better therapeutic outcome. Strategies for distinguishing between unipolar and bipolar depression are yet to be defined, resulting improper management. This study aims at comparing the socio-demographic and other variables between patients with unipolar and bipolar depression, along with assessment of severity of depression. Materials and Methods: This cross sectional study was conducted in a tertiary care psychiatry hospital in North-East India. The study included total of 330 subjects selected through purposive sampling technique from outpatient department after obtaining due informed consent. Mini-International Neuropsychiatric Interview (M.I.N.I.) version 6.0 and Beck Depression Inventory (BDI) were applied. Statistical Package for Social Sciences (SPSS) version 16.0 was applied for analysis. Results: Bipolar group had onset of illness at significantly younger age with more chronicity (32.85 ± 11.084). Mean BDI score was significantly higher in the unipolar depressive group. Conclusion: Careful approach in eliciting symptom severity and associated socio demographic profiles in depressed patients may be helpful in early diagnosis of bipolar depression. PMID:28250558

    Hairy cell leukaemia (HCL) is a B cell neoplasm which constitutes around 2 per cent of all the lymphoid leukaemias. It has a characteristic morphology and immunophenotypic profile. It is important to distinguish HCL from other B cell lymphoproliferative disorders due to availability of different chemotherapeutic agents. This study presents clinical, haematological and immunophenotypic profile of patients with HCL seen over a period of four years in a tertiary care hospital in north India. Twenty one cases of hairy cell leukaemia were analyzed for their clinical details, haemogram, bone marrow examination and immunophenotypic findings. Age of the patients ranged from 28-76 yr with male predominance. Weakness and fever were commonest presentations. Splenomegaly, hepatomegaly, lymphadenopathy were seen in decreasing order of frequency. Anaemia was noted in all 21 patients, leukopenia in 15 and thrombocytopenia in 19 cases. Fourteen patients were pancytopenic. Bone marrow examination showed typical hairy cells in all cases. Immunophenotyping showed expression of CD19, CD20, CD103, CD25 and CD11c in all cases, while positivity was seen for CD79b in 93.7 per cent, kappa light chain restriction in 60 per cent and lambda in 40 per cent cases. Notably, 20 per cent showed CD10 and 12 per cent showed CD23 expression. This study reveals some unusual findings in otherwise classical disease entity, like absence of palpable spleen, presence of lymphadenopathy, normal or elevated leukocyte counts, expression of CD10, which at times could be diagnostically challenging.

    There is a lack of information on the disease burden due to Taenia solium taeniasis and its associated risk factors in pig farming communities throughout the world. The present study was conducted in a rural pig farming community of north India to estimate the prevalence of T. solium taeniasis and associated factors. Demographic, clinical and epidemiological data were collected from 1181 subjects in 210 households in 30 villages. Stool specimens from 924 subjects were examined for eggs of Taenia and other parasites. Identification of T. solium was confirmed by morphological features of segments and species-specific DNA detection from segments and stool. The prevalence of T. solium taeniasis was 18.6% (172/924); factors associated with taeniasis on multivariate analysis were age above 15 years, history of passage of Taenia segments in stool, undercooked pork consumption and poor hand hygiene (hand-washing with clay/water after defecation). Seventy-eight subjects (6.6%) with epilepsy were identified. The study showed alarmingly high rates of epilepsy and T. solium taeniasis in the study community; it highlights the need for large-scale imaging-based surveys to identify the factors associated with epilepsy including neurocysticercosis. Health education, mass anthelminthic therapy and other preventive measures are required to control the menace of the disease.

    Outbreaks of enteric fever are a major health concern not only due to significant human morbidity and mortality but also fear of spread of multidrug resistant strains. We report an outbreak of enteric fever caused by Salmonella enterica serotype Typhi in a suburban area, in city Chandigarh of North India. Twenty-seven strains of S. typhi were isolated from blood cultures over a period of two weeks with 18 of these 27 patients residing in the same area. Maximum cases were in the age group 5-14 years (10 patients, 55.5%) while 4 (22.2%) cases were children under 5 years. All the strains showed similar resistogram being resistant to ampicillin and nalidixic acid, intermediate to ciprofloxacin and sensitive to chloramphenicol, ceftriaxone, cefotaxime, cotrimoxazole and azithromycin on disc diffusion testing. Minimum inhibitory concentration of ciprofloxacin was determined by agar dilution method and was found to be raised (≥ 2 μ g/mL). This nalidixic acid resistant S. typhi outbreak report warrants the necessity of implementing stringent sanitation practices in public health interest.

    Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is characterized by acute- or subacute-onset encephalopathy with extrapyramidal, psychiatric, and epileptic manifestations. Diagnosis is confirmed by positive antibodies to NMDA receptor in cerebrospinal fluid and serum. Eleven pediatric cases presented over a 2-year period at a tertiary care teaching hospital in North India. The average age at presentation was 9 years (range: 2.5 to 18 years, median: 10 years) with a slight female predominance (1.2:1). The common modes of presentation were progressive extrapyramidal syndrome with global neuroregression in 45% (5 of 11), epileptiform encephalopathy in 27% (3 of 11), and an overlap between the 2 in 27% (3 of 11). Fifty-eight percent showed significant response to steroids and intravenous immunoglobulin. This entity should be considered in an acute- or subacute-onset encephalopathy if common infectious etiologies are ruled out and there are specific clinical pointers. Early diagnosis and treatment significantly improves the outcome.

    Background Proper management of Biomedical waste (BMW) generated in a healthcare facility is one of the most important functions of a healthcare worker (HCW) as its improper management not only poses risk to human beings and environment, but may also invite legal action against HCW as well as hospital administration. This study was carried out to evaluate quality of BMW management in 1100-bedded hospital attached to a tertiary care public institute in North India. Methods A checklist, including 29 parameters related to various functions to be carried out at source of generation by a HCW for BMW management was prepared by researcher and used after validation to record observations in all the 70 areas of hospital. A total of 6 visits were made to each area and mean percentage score was calculated for each area and each category of waste management. Results It was found that summated mean percentage score of ‘Treatment Room of Wards’, which were used exclusively by resident doctors, was significantly lower than Operation Theatres (p value: 0.033) and ‘Central Waste Collection Points of Wards’ (p value: 0.018) for the function of ‘mutilation of recyclable waste’ and it was significantly lower than all other areas (p value: 0.006 to 0.017) for the function of ‘disinfection of waste’. Conclusion It is concluded that more emphasis needs to be laid on ‘mutilation of recyclable waste’ and disinfection of waste’ by HCWs especially resident doctors. PMID:24742274

    This study describes biochemical and biological properties of Naja kaouthia (Indian monocled cobra) venom of North-East India. The LD50 of the crude venom was found to be 0.148mg/kg and neurotoxicitic symptoms like paralysis of lower limbs and heavy difficulty in breathing at sub-lethal dose in mice was observed. The venom exhibited PLA2, indirect hemolytic and myotoxic activities but showed weak proteolytic and low direct hemolytic activities. It did not exhibit any hemorrhage when injected intradermally to mice. Anticoagulant activity was prominent when recalcification, prothrombin and activated partial thrombinplastin time were tested on platelet poor plasma. Rotem analysis of whole citrated blood in presence of venom showed delay in coagulation time and clot formation time. Fibrinogen of whole citrated blood was depleted by venom when analyzed in Sonoclot. Crude venom at 10µg and after 16hr of incubation was found to degrade α chain of fibrinogen. Neutralization study showed that Indian polyvalent antivenom could neutralize some of the biochemical and biological activities as well as its fibrinogenolytic activity. PMID:24349704

    The continuous soil gas radon monitoring is carried out at Palampur and the daily monitoring of radon concentration in water is carried out at Dharamshala region of Kangra valley of North West Himalayas, India, a seismic zone V, to study the correlation of radon anomalies in relation to seismic activities. In this study, radon monitoring in soil was carried out by using barasol probe manufactured by Algade France, whereas the radon content in water was recorded using RAD 7 radon monitoring system of Durridge Company USA. The effect of meteorological parameters viz. temperature, pressure, wind velocity, rainfall, and humidity on radon emission has been studied. The seasonal average value and standard deviation of radon in soil and water is calculated to find the radon anomaly to minimize the effect of meteorological parameters on radon emission. The radon anomalies observed in the region have been correlated with the seismic events of M>or=2 reported by Wadia Institute of Himalayas Geology Dehradoon and Indian Meteorological Department, New Delhi in NW Himalayas within 250km distance from the monitoring stations.

    We examined the effect of physical violence during pregnancy on perinatal and early-childhood mortality. We estimated the prevalence of domestic violence during pregnancy among a population-based sample of 2199 women in Uttar Pradesh, India. We used a survival regression model to examine the risks for perinatal, neonatal, postneonatal, and early-childhood (aged 1-3 years) mortality by mother's exposure to domestic violence, after we controlled for other sociodemographic and maternal health behavior risk factors. Eighteen percent of the women in our study experienced domestic violence during their last pregnancy. After we adjusted for other risk factors, births among mothers who had experienced domestic violence had risks for perinatal and neonatal mortality that were 2.59 (95% confidence interval [CI]=1.35, 4.95) and 2.37 (95% CI=1.21, 4.62) times higher, respectively, than births among mothers who had not experienced violence. We found no significant associations between domestic violence and either postneonatal or early-childhood mortality. Domestic violence is a significant risk factor for perinatal and neonatal mortality.

    The family Pentatomidae is one of the largest families of the sub-order Heteroptera, comprising 4722 species belonging to 896 genera. In the present paper, we analysed a partial ∼600 bp COI sequence of 14 species of family Pentatomidae, collected from northern part of India. For seven species viz., Tolumnia antennata Distant, 1902, Cahara jugatoria (Lethierry, 1891), Bagrada hilaris (Burmeister, 1835), Plautia viridicollis (Westwood, 1837), Priassus exemptus (Walker, 1868), Dalpada neoclavata (Rider, 1998) and Dalpada affinis (Dallas, 1851), this is the first ever molecular study which has generated distinct barcodes for each. The COI sequences of these seven species have been added to the existing database at GenBank NCBI which can be used for their identification. The database analysis shows mean K2P divergence of 2.5% at intraspecific level, 11.9% at interspecific level and 16.37% at intergeneric level, thereby indicating a hierarchical increase in K2P mean divergence across different taxonomic levels.

    Congenital cataract has the potential for inhibiting early visual development. Intrauterine infections with Rubella virus, Herpes simplex virus (HSV) and Toxoplasma gondii plays an important role in the development of congenital cataract. The study included 120 children under the age of 6 years presenting with congenital cataract and diagnosed using serology and polymerase chain reaction (PCR). The IgM positivity for rubella, HSV, T. gondii was found to be 5.8%, 1.6% and 8.3% respectively. The overall PCR positivity was found to be 40(33.3%), 25 (20.8%) and 39 (32.5%) for rubella, HSV and T. gondii with mean copy number of 1599 copies/μL; 1716 copies/μL and 1503 copies/μL respectively. Infective etiology significantly contributes to the causation of congenital cataract particularly for rubella virus which is a potentially eradicable disease. This study provides an epidemiological data for rubella, HSV and T. gondii in children with congenital cataract and highlights the need to introduce rubella vaccine in the National Immunization Programme of India.

    Introduction. HBV genotypes and subtypes are useful clinical and epidemiological markers. In this study prevalent HBV genotypes were assessed in relation to serological profile and clinical status. Material & Methods. 107 cases of HBV were genotyped. Detailed clinical history was elicited from them. HBsAg, HBeAg, anti-HBs, anti-HBe, and anti-HBc-IgM were assessed. HBV genotyping was performed using Kirschberg's type specific primers (TSP-PCR), heminested PCR, and Naito's monoplex PCR. Nucleotide sequencing was performed. Results. A total of 97 (91%) were genotyped following the methods of Kirschberg et al./Naito et al. Genotype D was by far the most prevalent genotype 91 (85.04%) in this region. A surprising finding was the detection of genotype F in 5 (4.67%) of our patients. Genotype A strangely was observed only in one case. In 85.7% genotype D was associated with moderate to severe liver disease, 43.9% HBeAg, and 18.7% anti-HBc-IgM positivity. Majority of genotype F (80%) was seen in mild to moderate liver disease. It was strongly associated with HBeAg 60% and 20% anti-HBc-IgM positivity. Conclusion. Emergence of genotype F in India merits further study regarding its clinical implications and treatment modalities. Knowledge about HBV genotypes can direct a clinician towards more informed management of HBV patients. PMID:24381592

    We report the seismogenic liquefaction signatures observed in the Kopili Fault Zone of the Brahmaputra plains, NE India. This seismically active zone has previously been identified as the "Assam seismic gap" and thus necessitates understanding its past seismicity and implied seismic hazard. With this objective, paleo-seismic studies using seismogenic liquefaction features have been carried out in this region largely covered with the flood plain deposits of Kopili and Kalang rivers. The trenches excavated at two locations revealed extensive liquefaction features with more than 20 sub parallel sand dykes having major orientation in NE-SW direction. A total of 29 samples from marker horizons have been processed to constrain chronology of the liquefaction features using optically stimulated luminescence (OSL) and 14C (AMS) dating techniques. The age constraints in terms of respective lower and upper bound age brackets for individual dykes suggest three time intervals of their formations i.e. (i) 250 ± 25 yr. BP, (ii) between 400 to 770 yr. BP and (iii) 900 ± 50 yr. BP. These new ages of liquefaction features correspond to the occurrence timings of causative seismic events which are in addition to the known historical earthquakes and thus enhance our understanding of the paleoseismic history of this region during past ~ 1000 years.

    Correct estimation of soil loss at catchment level helps the land and water resources planners to identify priority areas for soil conservation measures. Soil erosion is one of the major hazards affected by the climate change, particularly the increasing intensity of rainfall resulted in increasing erosion, apart from other factors like landuse change. Changes in climate have an adverse effect with increasing rainfall. It has caused increasing concern for modeling the future rainfall and projecting future soil erosion. In the present study, future rainfall has been generated with the downscaling of GCM (Global Circulation Model) data of Mandakini river basin, a hilly catchment in the state of Uttarakhand, India, to obtain future impact on soil erosion within the basin. The USLE is an erosion prediction model designed to predict the long-term average annual soil loss from specific field slopes in specified landuse and management systems (i.e., crops, rangeland, and recreational areas) using remote sensing and GIS technologies. Future soil erosion has shown increasing trend due to increasing rainfall which has been generated from the statistical-based downscaling method.

    Correct estimation of soil loss at catchment level helps the land and water resources planners to identify priority areas for soil conservation measures. Soil erosion is one of the major hazards affected by the climate change, particularly the increasing intensity of rainfall resulted in increasing erosion, apart from other factors like landuse change. Changes in climate have an adverse effect with increasing rainfall. It has caused increasing concern for modeling the future rainfall and projecting future soil erosion. In the present study, future rainfall has been generated with the downscaling of GCM (Global Circulation Model) data of Mandakini river basin, a hilly catchment in the state of Uttarakhand, India, to obtain future impact on soil erosion within the basin.

    Dengue, an acute viral disease transmitted by Aedes mosquitoes, is highly endemic in many tropical and subtropical areas of the world. Neurological complications of dengue infection have been observed more frequently in the recent past and some studies highlighted varied neurological complications arising in the course of dengue illness. In this retrospective study, we report various neurological complications observed during the last 2 years in patients of dengue fever. The patients presenting with neurological complications with positive serology (IgM antibody) for dengue infection were consecutively recruited from the Department of Neurology/Medicine from a tertiary center of Lucknow, India. These patients were subjected to a detailed clinical evaluation, laboratory assessment including blood count, hematocrit, coagulation parameters, biochemical assays, serology for dengue fever, enzyme-linked immunosorbent assay for human immunodeficiency virus and other relevant investigations. Twenty-six patients with neurological complications associated with confirmed dengue infection were observed during the last 2 years. Eighteen of these patients were male. Of the 26 patients, 10 patients were suffering from brachial neuritis, four patients had encephalopathy, three patients were consistent with the diagnosis of Guillain Barre syndrome, three patients had hypokalemic paralysis associated with dengue fever and two patients had acute viral myositis. Opsoclonus-myoclonus syndrome was diagnosed in two patients, myelitis in one patient and acute disseminated encephalo-myelitis also in one patient. Dengue fever was associated with widespread neurological complications. Brachial neuritis and opsoclonus-myoclonus syndrome were observed for the first time in this study.

    There is little documentation of the potential catastrophic effects of injuries on families due to out of pocket (OOP) expenditure for medical care. Patients who were admitted for at least one night in a tertiary care hospital of Chandigarh city due to injury were recruited and were followed-up at 1, 2 and 12 months after discharge to collect information on OOP expenditure. Out of the total 227 patients, 60% (137/227) had sustained road traffic injuries (RTI). The average OOP expenditure per hospitalisation and up to 12 months post discharge was USD 388 (95% CI: 332–441) and USD 1046 (95% CI: 871–1221) respectively. Mean OOP expenditure for RTI and non-RTI cases during hospitalisation was USD 400 (95% CI: 344–456) and USD 369 (95% CI: 313–425) respectively. The prevalence of catastrophic expenditure was 30%, and was significantly higher among those belonging to the lowest income quartile (OR-26.50, 95% CI: 6.70–105.07, p-value: <0.01) and with an inpatient stay greater than 7 days (OR-10.60, 95% CI: 4.21–26.64, p-value: <0.01). High OOP expenditure for treatment of injury puts a significant economic burden on families. Measures aimed at increasing public health spending for prevention of injury and providing financial risk protection are urgently required in India. PMID:27384572

    Background: Mucocutaneous diseases are among the first-recognized clinical manifestations of acquired immune deficiency syndrome. They function as visual markers in assessing the progression of human immunodeficiency virus (HIV) infection. Given the relative ease of examination of skin, its evaluation remains an important tool in the diagnosis of HIV infection. Objective: To determine the pattern of mucocutaneous manifestations in HIV-positive patients and to correlate their presence with CD4 counts. Materials and Methods: This cross-sectional study included 352 HIV-infected patients seen at PGIMER, Chandigarh, India, over a period of 1 year. The patients were screened for mucocutaneous disorders by an experienced dermatologist. The patients were classified into different stages according to the World Health Organization clinical and immunological staging system. Results: The most prevalent infection was candidiasis, seen in 57 patients (16.2%). Prevalence of candidiasis, dermatophytosis, herpes simplex, herpes zoster, molluscum contagiosum (MC), seborrheic dermatitis, adverse drug reaction, nail pigmentation, xerosis and diffuse hair loss differed statistically according to the clinical stages of HIV infection. There was a statistically significant association between immunological stages of HIV infection and dermatophytosis. Conclusion: Results of our study suggest that mucocutaneous findings occur throughout the course of HIV infection. Dermatoses like MC and dermatophytosis show an inverse relation with CD4 cell count, and these dermatoses can be used as a proxy indicator of advanced immunosuppression to start highly active anti-retroviral therapy in the absence of facilities to carry out CD4 cell count.

    The present paper is based on the Research Project entitled "Impact of Technological and Economic Development Programme on Bio-Cultural Heritage of Gaddis and Pangwalas Population Groups of Himachal Pradesh". The project was framed after UNESCO/MAB Project Nos. 6 and 12 under UNESCO Programme on Man Biosphere (MAB) and supported by the Department of Science and Technology, Government of India. The population groups under investigation are: 1. Transhumant Gaddis of Bharmour Sub-Tehsil, Chamba District; 2. Settled Gaddis of Kangra District; and 3. Pangwalas of Pangi Tehsil, Chamba District, Himachal Pradesh. The carrying capacity has been calculated for Pangi and Bharmour Sub-Tehsil and it has been observed that in both the places the size of population is beyond the capacity of the land. The pattern of body growth and respiratory functions among Transhumant Gaddis of Bharmour Sub-Tehsil, Chamba District and Settled Gaddis of Kangra District have been studied. Statistically non-significant differences in most of the biological variables have been observed among these groups.

    Although there is increasing recognition of the global scope of domestic violence and the potential reproductive health consequences of violence, little is known about the relationship between physical and sexual domestic violence and gynecologic morbidity in developing country settings. A sample of 3,642 couples from northern India was created by matching husbands and wives who responded to the men's and women's surveys of the 1995-1996 PERFORM System of Indicators Survey. The association between men's reports of physical and sexual violence they had perpetrated against their wives and wives' reports of gynecologic symptoms was analyzed in bivariate and multivariate analyses. Overall, 37% of men said they had committed one or more acts of physical or sexual violence against their wives in the past 12 months, with 12% reporting physical violence only, 17% sexual violence only and 9% both physical and sexual violence. Thirty-four percent of women reported at least one symptom of gynecologic morbidity. Compared with women whose husbands reported no violence, those who had experienced both physical and sexual violence and those who had experienced sexual violence only had elevated odds of reporting gynecologic symptoms (odds ratios, 1.7 and 1.4, respectively). Plausible mechanisms through which domestic violence may influence gynecologic morbidity include physical trauma, psychological stress or transmission of STIs. Reproductive health care that incorporates domestic violence support services is needed to meet the special needs of abused women.

    One of the principal problems facing palaeodemography is age estimation in adult skeletons and the centrist tendency that affects many age estimation methods by artificially increasing the proportion of individuals in the 30-45-year age category. Several recent publications have indicated that cementum annulations are significantly correlated with known age of extraction or death. This study addresses the question of how demographic dynamics are altered for an archaeological sample when cementum-based age estimates are used as opposed to those obtained via conventional macroscopic methods. Age pyramids were constructed and demographic profiles were compared for the early Holocene skeletal population from Damdama (India). The results demonstrate that the use of cementum annulations for age estimation in only a subset of the skeletal sample has a significant impact on the demographic profile with regard to specific parameters such as mean age at death and life expectancy at birth. This confirms the importance of using cementum annulations to refine age estimates in archaeological samples, which, when combined with a fertility-centred approach to demography, can provide new insights into population dynamics in the past.

    Psychiatric disorders in India are often attributed to influence of supernatural phenomena, and many patients are subjected to various kinds of 'magico-religious' treatments. We studied 40 cases of schizophrenia and ascertained magico-religious beliefs held by their key relatives. The effects of such magico-religious beliefs on psychopathology and treatment-seeking behaviour were explored. The sample were schizophrenia patients diagnosed according to ICD-10 of the World Health Organisation. Psychopathology was assessed on the 9th version of the Present State Examination (PSE-9). Supernatural Attitude Questionnaire was administered to the key relatives of the patients to ascertain their beliefs about various supernatural phenomena and magico-religious treatments. It was observed that the majority of the patients had undergone magico-religious treatment (n = 23). Nearly 74% of the patients who had symptoms coloured by cultural influences such as delusional explanation in terms of paranormal phenomena had undergone magico-religious treatment. It was also seen that though many relatives denied personal conviction in such magico-religious beliefs, yet they sought some kind of magico-religious treatment for the patients. The prevalence of culturally influenced delusions as defined by the PSE-9 was very low. Belief in supernatural influences is common in patients' relatives from urban background and with adequate education, and treatment based upon such beliefs is sought to a considerable extent in such cases. Local and community belief in such phenomena appeared to be a factor in influencing the decision to seek magico-religious treatment.

    The behaviour of so called traditional patients has been the topic of anthropological research for the last thirty years. Myths have been and constructed and rejected, one being that patients with chronic and less incapacitating illness see rather traditional healers than allopathic medical treatment. The case study with which we are concerned in this paper is the illness of a young girl who is the age in which she is expected to accept a marriage contract. Since she is obviously not willing to do she adopts an illness behaviour which enables her to postpone all role expectations of her age group. She performs a behaviour which is socially accepted and guarantees all the support from her family which she needs and requires. The paper investigates the causes, reason and development of her spirit possession and relates it to the cultural grammar of the patient's group of reference. The data of this case study were obtained at a Muslim shrine in Gujarat, India. PMID:22557510

    Background: Preeclampsia in pregnancy has been shown to be associated with low serum calcium level. Though the evidence is abundant, it is equivocal. Objectives: The study aimed to estimate the dietary calcium intake and serum calcium status among pregnant women, and to document the association of the dietary calcium intake and serum calcium status with incidence of preeclampsia in the 3rd trimester of pregnancy. Materials and Methods: A community-based cross-sectional study was conducted in the Health and Demographic Surveillance System (HDSS) site, Ballabgarh, Haryana, India. All pregnant women between 28 weeks and 36 weeks of gestation were interviewed. A semi-structured interview schedule and a 24-h dietary recall questionnaire were administered to assess the dietary calcium intake. AutoAnalyser (Biolis 24i) was used for measuring serum calcium. Results: We enrolled 217 pregnant women. The mean [standard deviation (SD)] dietary calcium intake was 858 (377) mg/day. The mean (SD) serum calcium level was 9.6 mg/dL (0.56). Incidence of preeclampsia was 13.4%. Preeclampsia was not associated with hypocalcemia [odds ratio (OR) = 1.2 95% confidence interval (CI); 0.27-3.98]. Conclusion: The majority of pregnant women had inadequate dietary calcium intake. The prevalence of hypocalcemia was low. Low serum calcium level was not associated with preeclampsia. Calcium supplementation may not reduce preeclampsia in this population. PMID:27385877

    The current study area is coastal zone of Visakhapatnam, district of Andhra Pradesh along the coast of India. This area is mostly vulnerable to many disasters such as storms, cyclone, flood, tsunami and erosion. This area is considered as cyclone prone area because of frequently occurrence of the cyclones in this area. Recently the two tropical cyclones that formed in the Bay of Bengal are Hudhud (October 13, 2014) and Phylin (October 11, 2013), has caused devastating impacts on the eastern coast and shows that the country has lack of preparedness to cyclone, storm surge and related natural hazards. The multi-hazard vulnerability maps prepared here are a blended and combined overlay of multiple hazards those affecting the coastal zone. The present study aims to develop a methodology for coastal multi-hazard vulnerability assessment. This study carried out using parameters like probability of coastal slope, tsunami arrival height, future sea level rise, coastal erosion and tidal range. The multi-hazard vulnerability maps prepared by overlaying of multi hazards those affecting the coastal zone. Multi-hazard vulnerability maps further reproduced as risk maps with the land use information. The decision making tools presented here can provide a useful information during the disaster for the evacuation process and to evolve a management strategy.

    Bloodstream infections are associated with significant patient morbidity and mortality worldwide. In this study, we examined antimicrobial susceptibility patterns by reviewing the data on 5,704 blood samples that were collected from patients with fever/sepsis admitted to Government Medical College and Hospital, Chandigarh, India, over a period of 1 year from August 2003 to July 2004. Among the 567 qualifying samples, Pseudomonas aeruginosa (19.75%), Escherichia coli (15.17%), Klebsiella pneumoniae (14.99%), and Salmonella enterica serovar Typhi (12.87%) were the most frequently isolated Gram-negative bacteria other than Citrobacter, Acinetobacter, Proteus, and Enterobacter spp. collectively accounting for 80.96% of the isolates. Staphylococus aureus (13.86%) and Enterococcus feacalis (2.35%) were most frequently isolated Gram-positive bacteria other than other Streptococcus and Staphylococcus spp. collectively accounting for 18% of the isolates. Among the antibiotics used for susceptibility testing of Gram-negative isolates, amikacin showed higher activity (76.61%) against Enterobacteriaceae and ciprofloxacin (65.17%) against non-fermenters. However, cefoperazone + sulbactum showed the highest activity (82.66%) among all Gram-negative isolates. For Gram-positive isolates, vancomycin (100%), ciprofloxacin (89.74%) showed the highest activity against Staphylococcus spp. Combinations of antibiotics are often prescribed as emperic therapy for bacteremia, especially for Gram-negative pathogens. Hence the antibiotic susceptibility patterns of blood isolates reported here may be a useful guide for physicians initiating emperic therapy with antibiotics.

    Background: Noncommunicable diseases have become a public heath problem in India concomitant with economic development, leading to increases in tobacco consumption, obesity, and changes in diet and lifestyle. Although observation suggests that tobacco consumption is a major risk factor for deaths due to circulatory, pulmonary, and malignant diseases, such studies are not available from most populations in developing countries. Subjects and methods: For the period 1999–2001, we studied the randomly selected records of death of 2222 (1385 men and 837 women) decedents, aged 25–64 years, out of 3034 death records overall from the records at Municipal Corporation, Moradabad. All the families of these deceased could be contacted individually to find out the causes of death, by scientist/doctor administered, informed consented, verbal autopsy questionnaire, completed with the help of the spouse and local treating doctor practicing in the appropriate healthcare region. Social classes and tobacco intakes were assessed by a questionnaire. Results: The prevalence of tobacco consumption, including chewing + smoking, were 45% (n = 623) among men and 15% (n = 125) among women decedents. However, smoking was observed in 20% and tobacco chewing in 30% of male decedents, while only 6% of female decedents smoked and 10% chewed tobacco. Social class had no impact on tobacco consumption in men but did influence one subgroup >55 years among women, ie, among those who had the highest tobacco consumption. Tobacco intakes were significantly more common among decedents dying due to circulatory, malignant, and pulmonary diseases, compared with other causes (men 61.1%, 76.6%, pulmonary 77.3% vs 31%, P < 0.001; women 27.5%, 75.9%, pulmonary 24.6% vs 0.42%, P < 0.001) of mortality, respectively. Pulmonary causes included chronic bronchitis and asthma. Circulatory diseases (29.1%, n = 646) including heart attacks (10.0%), stroke (7.8%), valvular heart disease (7.2%, n = 160), sudden cardiac

    The supply of good quality food is main necessity for economic and social health of urban and rural population throughout the globe. This study comes to know the severity of As in the west Bengal and north-eastern states of the India. Over the 75% large population of India lives in villages and associated with farming and its related work. West Bengal is the densest populated area of India, fish and rice is the staple food as well as in north-eastern states. For the fulfil demand of fish large population the area are used fisheries as the business. Arsenic contamination in ground water is major growing threat to worldwide drinking water resources. High As contamination in water have been reported in many parts of the world Chandrasekharam et al., 2001; Smedley and Kinniburgh, 2002; Farooq et al., 2010). In context to West Bengal and north-east states of India arsenic is main problem in the food chain. These areas are very rich in arsenic many fold higher concentrations of Arsenic than their respective WHO permissible limits have been reported in the water. Over the 36 million people in Bengal delta are at risk due to drinking of As contaminated water (Nordstrom, 2002). The highest concentration of arsenic (535 μg/L Chandrashekhar et al. 2012) was registered from Ngangkha Lawai Mamang Leikai area of Bishnupur district which is fifty fold of the WHO limit for arsenic and tenfold of Indian permissible limit. With the continuous traditional practicing (As rich water pond) and untreated arsenic rich water in fish industries leads to health hazards. A sustainable development in aquaculture should comprise of various fields including environmental, social, cultural and economic aspects. A scientific study has to be needed for the overcome on this problem and rain harvested water may be used for reduce the arsenic problems in fisheries.

    Uttarakhand, Northern India is facing challenges in the issues concerning public health. Hence, researches identifying the stressors and nutri-tional factors influencing health are encouraged. This study attempts to assess the stress levels and nutritional status. Gender differences are also measured in the same. Stress and nutritional status related information was gathered (Nov, 2012-June, 2013) from 118 individuals residing in Uttarakhand state. Stress level was assessed using Personal Stress Score Inventory. Anthropo-metric details and dietary intake (3 day food recall method) were collected. Nutrient intake were calculated and compared with recommended dietary allowance (RDA) for Indi-ans. T-test and Chi-square (χ²) were performed to measure the gender difference in studied variables. 66.6% of females and 85.4% of males reported moderate stress (31-79). Males were seen to be more stressed then females, though no sig-nificant differ-ence was seen. A significant difference in BMI (Body mass Index) was seen be-tween males (24.1 kg/m(2)) and females (21.5 kg/m(2)). The study sample was found to be deficient in iron and zinc when compared with RDA. Females suf-fering from various level of stress had significantly lower levels of energy, pro-tein, zinc than males. Majority of subjects were suffering from moderate level of stress. The anthropometric status of subjects was good, though females showed signifi-cantly lower intake of nutrients compared to men. Poor intake of iron and zinc points towards a possibility of hidden hunger. Hence, psy-chological and nutri-tional counseling may be required.

    Tropospheric pollutants including surface ozone (O3), nitrogen dioxide (NO2), carbon monoxide (CO) and meteorological parameters were measured at a traffic junction (78°2' E and 27°11' N) in Agra, India from January 2012 to December 2012. Temporal analysis of pollutants suggests that annual average mixing ratios of tropospheric pollutants were: O3 - 22.97±23.36ppbV, NO2 - 19.84±16.71ppbV and CO - 0.91±0.86ppmV, with seasonal variations of O3 having maximum mixing ratio during summer season (32.41±19.31ppbV), whereas lowest was found in post-monsoon season (8.74±3.8ppbV). O3 precursors: NO2 and CO, showed inverse relationship with O3. Seasonal variation and high O3 episodes during summer are associated with meteorological parameters such as high solar radiation, atmospheric temperature and transboundary transport. The interdependence of these variables showed a link between the daytime mixing ratios of O3 with the nighttime level of NO2. The mixing ratios of CO and NO2 showed tight correlations, which confirms the influence of vehicular emissions combined with other anthropogenic activities due to office/working hours, shallowing, and widening of boundary layer. FLEXTRA backward trajectories for the O3 episode days clearly indicate the transport from the NW and W to S/SE and SW direction at Agra in different seasons. Copyright © 2017.

    Pseudotachylitic breccia (PTB) occurs in a drill core from the crater floor of the 11 km diameter, Proterozoic Dhala impact structure, India. PTBs were intersected in late Archean granitoids between 348.15 m and 502.55 m depth in the MCB-10 drill core from the center of the Dhala structure. The breccias comprise both cataclastic-matrix as well as melt breccias. The presence of microlites and vesicles in the groundmass and a widely observed flow fabric in the PTB support the presence of melt in the groundmass of some samples. Clasts in PTB are derived from the Archean granitoid basement. PTB matrix, the matrix of impact melt breccia also occurring between 256.50 m and 502.55 m depth, and the target granitoids vary in terms of silica, total alkali, magnesium and iron oxide contents. Chondrite-normalized REE patterns of PTB and target granitoids are similar, but the elemental abundances in the PTB are lower. The restricted size of PTB as veins and pods of up to 2.5 cm width, their occurrence at varied depths over a core length of 150 m, the clast population, and the chemical relationships between PTB and their host rocks all suggest the derivation of these breccias locally from the fractured basement granitoids involving in-situ melting. We favor that this took place due to rapid decompression during the collapse and modification stage of impact cratering, with, locally, additional energy input from frictional heating. Locally, amphibolite and dioritic mylonite occur in the host granitoids and their admixture could have contributed to the comparatively more mafic composition of PTB. Alteration of these crater floor rocks could have involved preferential reduction of silica and alkali element abundances, possibly due to impact-induced hydrothermal activity at crater floor level. This process, too, could have resulted in more mafic compositions.

    Background: Urinary tract infections (UTIs) remain a major problem both in hospitalized and outdoor patients. Multidrug-resistant enterococci are emerging as a major nosocomial pathogen with increasing frequency. However, the incidence of community-acquired enterococcal infections and species prevalent in India is not thoroughly investigated. Objectives: This study aims to estimate the burden of community-acquired UTIs seen at a tertiary care hospital and to identify the Enterococcus species isolated from these patients. The study also aims to determine the antibiotic susceptibility pattern with reference to high-level aminoglycosides and vancomycin. Materials and Methods: Semi-quantitative cultures from a total of 22,810 urine samples obtained from patients seen at various Outpatient Departments were analyzed. From them 115 nonduplicate isolates of enterococci were obtained as significant pure growth (>105 cfu/ml) and speciated. Antibiotic susceptibility was performed by Kirby–Bauer disc diffusion method. Vancomycin resistance screening was performed by the vancomycin screen agar method recommended by Clinical and Laboratory Standards Institute and confirmed by determination of minimum inhibitory concentration by agar dilution method. Results: Of 115 enterococcal isolates, 61 were identified as Enterococcus faecalis, 42 as Enterococcus faecium, 3 each as Enterococcus dispar, and Enterococcus pseudoavium. High-level gentamicin resistance (HLGR) was higher in E. faecium (47.6%) than E. faecalis (32.7%) and HLSR also showed the same pattern with 47.6% and 27.9% resistance, respectively. Vancomycin resistant enterococci accounted for 11.3% of the isolates, and out of them 53.8% were E. faecium by agar dilution method. Conclusion: High rate of resistance to antibiotics of penicillin group and aminoglycosides was observed in our tertiary care hospital even in community acquired UTIs. Hence, there is an urgent need for more rational and restricted use of antimicrobials

    Background Data on eye diseases among school children is not readily available. Considering the fact that one-third of India's blind lose their eyesight before the age of 20 years and many of them are under five when they become blind, early detection and treatment of ocular morbidity among children is important. Aim To estimate the prevalence of ocular morbidity among school children of age 6-16 years. Settings Government and private coeducational schools in urban area of Shimla. Design Cross-sectional Materials and Methods Government and private coeducational schools selected by stratified random sampling. About 1561 school children, studying in elementary through secondary class in these schools were examined from August 2001 to January 2002 in Shimla. A doctor did visual acuity and detailed ophthalmic examination. Statistical analysis The Chi-square test was used to test differences in proportions. Differences were considered to be statistically significant at the 5% level. Results Prevalence of ocular morbidity was 31.6% (CI=29.9-32.1%), refractive errors 22% (CI=21.1-22.8%), squint 2.5% (CI=2.4-2.6%), color blindness 2.3% (CI=2.2-2.4%), vitamin A deficiency 1.8 % (CI=1.7-1.9%), conjunctivitis 0.8% (CI=0.79-0.81%). Overall prevalence of ocular morbidity in government and private schools did not show any statistical significant difference. Prevalence of conjunctivitis was significantly (P<0.5) more in government schools. Conclusion A high prevalence of ocular morbidity among high-school children was observed. Refractive errors were the most common ocular disorders. PMID:19237787

    Opportunity for natural selection among five population groups of Manipur in comparison with other North East Indian population has been studied. Crow's index as well as Johnston and Kensinger's index for natural selection were calculated based on differential fertility and mortality. The mortality component was found to be lower compared to fertility component in all the populations which may attribute to comparatively improved and easily accessible health care facilities. However, different selection pressures, artificial and natural, seem to be influencing the selection intensity through induced abortion and spontaneous abortion among the two non-tribal migrant groups: Bamon and Muslims, respectively. This study highlights the probable interaction of artificial and natural selection in determining the evolutionary fate of any population group.

    Over the last fifty years, changes in agriculture brought about by the Green Revolution have transformed India from a famine-prone, drought-susceptible country into the worlds' third largest grain producer and one of the most intensively irrigated parts of the globe. Regionally, cheap energy, subsidised seeds and fertilisers, and in some areas Government purchase guarantees for grain promote the intensification of farming. While this allows farmers to survive, it also aggravates the drain agriculture is having on resources, particularly energy and water. Analysis at a regional scale, however, masks the considerable spatial variability that exists on a more localised level and must be taken into consideration to understand correctly aggregate system response to policy, hydrologic, and climatic change. In this study we present and analyse the results from over 100 farmer interviews conducted in the data-scarce districts of Jalaun and Sitapur on the Gangetic Plains of Uttar Pradesh during the post monsoon period of 2013. Variables such as the volumes and timing of irrigation water applied, sources of water, methods of abstraction and irrigation, and costs incurred are mapped, using qualitative data analysis and GIS. Large differences between the districts emerge, for instance in the region of Jalaun where cheaper canal water is available in addition to groundwater. This has enabled farmers to afford more water efficient technologies such as sprinklers, a practice not found in Sitapur which depends almost exclusively on more expensive diesel pumps. Results are used to delineate the spatial variability in water use practices, along with farmer behaviour and decision making. The primary data are compared with socio-economic information taken from regionally produced statistical abstracts. The combined data are used to identify the main drivers that influence farmer decision-making, which is in turn leading to groundwater overdraught in many parts of North India. Finally

    Background Establishing personal identity is one of the main concerns in forensic investigations. Estimation of stature forms a basic domain of the investigation process in unknown and co-mingled human remains in forensic anthropology case work. The objective of the present study was to set up standards for estimation of stature from the foot and its segments in a sub-adult female population. Methods The sample for the study constituted 149 young females from the Northern part of India. The participants were aged between 13 and 18 years. Besides stature, seven anthropometric measurements that included length of the foot from each toe (T1, T2, T3, T4, and T5 respectively), foot breadth at ball (BBAL) and foot breadth at heel (BHEL) were measured on both feet in each participant using standard methods and techniques. Results The results indicated that statistically significant differences (p < 0.05) between left and right feet occur in both the foot breadth measurements (BBAL and BHEL). Foot length measurements (T1 to T5 lengths) did not show any statistically significant bilateral asymmetry. The correlation between stature and all the foot measurements was found to be positive and statistically significant (p-value < 0.001). Linear regression models and multiple regression models were derived for estimation of stature from the measurements of the foot. The present study indicates that anthropometric measurements of foot and its segments are valuable in the estimation of stature. Foot length measurements estimate stature with greater accuracy when compared to foot breadth measurements. Conclusions The present study concluded that foot measurements have a strong relationship with stature in the sub-adult female population of North India. Hence, the stature of an individual can be successfully estimated from the foot and its segments using different regression models derived in the study. The regression models derived in the study may be applied successfully for the

    North East India, nestled between the southeastern Tibetan Plateau on the north, the Indo Myanmar range of hills to the east, plains of Bangladesh to the south and the Indo-Gangetic plains (IGP) to the west has a unique topography and population inhabitation pattern. In recent decades, along with other parts of south Asia NE India has undergone rapid industrial and economic development. Lifestyle changes have increasingly added to the anthropogenic burden on the atmosphere in the plains while biomass burning due to shifting cultivation in the hills is a major source of particulate and gaseous pollution. Studies have suggested that during the Asian summer monsoon, boundary layer pollution from India, Southeast Asia and south China are lifted to the upper tropospheric region by convection followed by westward transport over the Middle East and the Mediterranean. The spatio-temporal variation of aerosol optical (viz. AOD, AAI, AAOD, AE, FMF, columnar mass concentration (CMC)) and radiative properties are studied using data from multiple satellite sensors: MODIS, OMI, TOMS, CERES at various locations within the NE India (22-30°N, 86-98°E) for the period 2000-2012. Significant spatio-temporal variation of aerosol optical and radiative properties is observed within the region. For example, Guwahati, the metropolitan city, shows maximum value of AOD, followed by Dhubri the location situated at the western corridor of north-east India. Minimum AOD is observed at the high altitude locations Thimphu and Tawang. Temporally AOD is overriding in March, April, May (MAM) at almost all the observation locations. The minimum AOD over the region in October-November (ON) is associated with the topography and local meteorology. AAI >0.5 at all the locations indicates presence of significant amount of absorbing aerosols. The peak AAI and AAOD in MAM at all the location is associated with the peak biomass burning activity and long range transportation from other locations of India and

    Phlebotomus argentipes is considered to be one of the major control measure targets in eradicating visceral leishmaniasis (VL). This study demonstrates the spatial association of P. argentipes abundance in relation to agricultural environment in the endemic area of north Bihar. Vector data were collected from the 95 villages of the study area using a handheld aspiration technique. Space technology and ground observationwere made to estimate the environmental characteristics. A total of 1,663 P. argentipes were collected between April and November 2011. Results showed negative and significant association between P. argentipes density and proximity to the agricultural land in both the dry (r = -0.39) and wet seasons (r = -0.55), respectively. A strong and positive association was observed between relative humidity and P. argentipes abundance (r = 0.55). Results illustrated a very strong positive association between soil moisture and P. argentipes abundance (r = 0.58). The agricultural land class density and the spatial abundance of P. argentipes showed a very strong and positive association (r = 0.46). This study will help in understanding the advantage of agricultural land use practices to delineate of P. argentipes habitat suitability, which may strengthen existing control strategies in this endemic area.

    Infection due to Mycobacterium bovis typically occurs in cattle and animals transmit infection to each other. The choice of appropriate clinical specimen is very important for isolation of M. bovis and M. tuberculosis from cattle. The present study reports the isolation of M. tuberculosis and M. bovis from different types of specimens from cattle suspected to be suffering from tuberculosis in certain organized cattle farms in north India. A total of 768 specimens (heparinized or EDTA containing blood (162), fine needle aspirates from prescapular lymph gland (PSLG,160), milk (154), pharyngeal swab (PhS, 98), rectal pinch (RP, 97) and faecal sample (97) from 161 cattle of organized cattle farms in north India suspected to be suffering from tuberculosis were analyzed. After decontamination by modified Petroff's method isolation of M.tuberculosis complex was done on Lowenstein-Jensen medium (with and without pyruvate). The culture isolates were identified as M. tuberculosis and M. bovis on the basis of biochemical tests. A total of 54 M. tuberculosis complex isolates were obtained, of them 40 were identified as M.bovis and 14 as M. tuberculosis. M.bovis were isolated from 12 of 38 animals in group A (Tuberculin +ve with signs of tuberculosis), 7 of 37 animals in group B (Tuberculin +ve and apparently healthy), 9 of 21 group C animals in (Tuberculin -ve with clinical signs of tuberculosis), 4 of 26 animals in group D (Tuberculin -ve and apparently healthy), 4 of 27 group E animals (having non-mycobacterial infection) and 4 of 12 animals in group F (having clinical signs such as debilitated condition, cough, decreasing milk production, etc). Maximum number of M. bovis (19/40, 47.5%) and M. tuberculosis (5/14, 35.7%) isolates were grown from prescapular lymph gland biopsy (PSLG) followed by blood from which 9/40 (22.5%) M. bovis and 4/14 (28.5%) M. tuberculosis were isolated. M. bovis [6/40(15%)] and M. tuberculosis [4/14(28.5%)] were also isolated from milk. Only 3/40 (7

    Fluoroquinolone resistance in both Gram-positive and Gram-negative bacteria has increased with the widespread use of fluoroquinolones. Fluoroquinolone resistance in Gram-negative bacilli has been widely studied, though staphylococci and enterococci are also notably resistant. Enterococci being the second most common cause of healthcare-associated urinary tract infections (UTIs) fluoroquinolones are often the drug of choice. This study was undertaken to assess the risk factors associated with fluoroquinolone-resistant enterococcal UTI in a tertiary level health facility in north India. A total of 365 patients with UTI caused by enterococci were studied over a period of two years. Patients with ciprofloxacin-resistant and susceptible UTI were considered as cases and controls, respectively. Resistance profile of the isolates against common antibiotics was studied by minimum inhibitory concentration (MIC) determination. Mechanisms for fluoroquinolone resistance was studied by efflux pump inhibitor activity and multiplex PCR targeting the qnr genes. A total of 204 (55.89%) cases and 161 (44.1%) controls were identified. The fluoroquinolone-resistant isolates were significantly resistant to ampicillin, high strength aminoglycosides and vancomycin. The majority (78%) of the resistant isolates showed efflux pump activity. Treatment in indoor locations, presence of urinary catheters and pregnancy along with recent exposure to antibiotics especially fluoroquinolones, third generation cephalosporins and piperacillin-tazobactam were identified as independent risk factors. Our results showed that fluoroquinolone resistance in enterococcal UTI was largely associated with indoor usage of antibiotics and use of indwelling devices. Knowledge of risk factors is important to curb this emergence of resistance.

    Introduction: Occupational hazards such as accidental exposure to sharp, cuts, and splashes are common among health-care workers (HCWs). Aims and Objectives: To determine the occurrence of self-reported occupational exposures to these hazards and to know the prevalent practices following the exposure. The second aim was to know the baseline antibody levels against hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) immediately after these accidents. Methods: An observational prospective study was done in the HCWs of a tertiary care academic health organization of North India from January 2011 to December 2013. At the time of self-reporting of injury, a questionnaire was administered. Blood sample of HCWs and of the source, if identified, was collected for baseline HBV, HCV, and HIV serum markers. The exposed HCWs were followed up and repeat testing was done after 3–4 weeks for seroconversion up to 6 months. Results: A total of 476 injuries were reported. Needlestick injury of fingers was the most common. Doctors were found to have the highest exposure rate (73.7%) distantly followed by nurses (19.1%). A significant number of the HCWs (125, 26.3%) vaccinated in past had hepatitis B surface antibody (anti-HBs) titers <10 mIU/mL (protection defined as anti-HBs level ≥10 mIU/ml). Only 44 sources were found to be seropositive (11 for HIV, 9 for HCV, and 24 for HBV). No seroconversion was seen in any of the exposed HCWs after 6 months. Conclusions: The incidence of needlestick and sharp injuries is most often encountered in emergency wards. Anti-HBs titers were suboptimal in many of the HCWs requiring a booster dose of HBV vaccination. PMID:28042212

    Clay mineral assemblages of a soil chrono-association comprising five fluvial surface members (QGH1 to QGH5) of the Indo-Gangetic Plains between the Ramganga and Rapti rivers, north-central India, demonstrate that pedogenic interstratified smectite-kaolin (Sm/K) can be considered as a potential indicator for paleoclimatic changes during the Holocene from arid to humid climates. On the basis of available radiocarbon dates, thermoluminescence dates, and historical evidence, tentative ages assigned to QGH1 to QGH5 are <500 yr B.P., >500 yr B.P., >2500 yr B.P., 8000 TL yr B.P., and 13,500 TL yr B.P., respectively. During pedogenesis two major regional climatic cycles are recorded: relatively arid climates between 10,000-6500 yr B.P. and 3800-? yr B.P. were punctuated by a warm and humid climate. Biotite weathered to trioctahedral vermiculite and smectite in the soils during arid conditions, and smectite was unstable and transformed to Sm/K during the warm and humid climatic phase (7400-4150 cal yr B.P.). When the humid climate terminated, vermiculite, smectite, and Sm/K were preserved to the present day. The study suggests that during the development of soils in the Holocene in alluvium of the Indo-Gangetic Plains, climatic fluctuations appear to be more important than realized hitherto. The soils older than 2500 yr B.P. are relict paleosols, but they are polygenetic because of their subsequent alterations.

    Harm reduction packages for people who inject illicit drugs, including those infected with human immunodeficiency virus (HIV), are cost-effective but have not been scaled up globally. In the north-eastern Indian states of Manipur and Nagaland, the epidemic of HIV infection is driven by the injection of illicit drugs, especially opioids. These states needed to scale up harm reduction programmes but faced difficulty doing so. In 2004, the Bill & Melinda Gates Foundation funded Project ORCHID to scale up a harm reduction programme in Manipur and Nagaland. In 2003, an estimated 10 000 and 16 000 people were injecting drugs in Manipur and Nagaland, respectively. The prevalence of HIV infection among people injecting drugs was 24.5% in Manipur and 8.4% in Nagaland. By 2012, the harm reduction programme had been scaled up to an average of 9011 monthly contacts outside clinics (80% of target); an average of 1709 monthly clinic visits (15% of target, well above the 5% monthly goal) and an average monthly distribution of needles and syringes of 16 each per programme participant. Opioid agonist maintenance treatment coverage was 13.7% and retention 6 months after enrolment was 63%. Antiretroviral treatment coverage for HIV-positive participants was 81%. A harm reduction model consisting of community-owned, locally relevant innovations and business approaches can result in good harm reduction programme scale-up and influence harm reduction policy. Project ORCHID has influenced national harm reduction policy in India and contributed to the development of harm reduction guidelines.

    Acute Encephalitis Syndrome (AES) and Japanese Encephalitis (JE) stay as poorly understood phenomena in India. Multiple linkages to determinants such as poverty, socio-economic status, gender, environment, and population distribution, make it a greater developmental issue than just a zoonotic disease. A qualitative study was conducted to map knowledge, perceptions and practices of community and health systems level stakeholders. Seventeen interviews with utilizers of AES care, care givers from human and veterinary sectors, Non-governmental Organizations (NGOs), and pig owners and 4 Focused Group Discussions (FGDs) with farmers, community leaders, and students were conducted in an endemic north Indian district-Kushinagar. Core themes that emerged were: JE/AES been perceived as a deadly disease, but not a major health problem; filthy conditions, filthy water and mosquitoes seen to be associated with JE/AES; pigs not seen as a source of infection; minimal role of government health workers in the first-contact care of acute Illness; no social or cultural resistance to JE vaccination or mosquito control; no gender-based discrimination in the care of acute Illness; and non-utilization of funds available with local self govt. Serious challenges and systematic failures in delivery of care during acute illness, which can critically inform the health systems, were also identified. There is an urgent need for promotive interventions to address lack of awareness about the drivers of JE/AES. Delivery of care during acute illness suffers with formidable challenges and systematic failures. A large portion of mortality can be prevented by early institution of rational management at primary and secondary level, and by avoiding wastage of time and resources for investigations and medications that are not actually required.

    Aim: This study was conducted to determine the incidence of major reproductive problems of dairy cattle reared under a semi-intensive system by small and marginal farmers in Meghalaya province of North-Eastern India. Materials and Methods: In a 3 years study, a total of 576 crossbred dairy cattle (212 Holstein Friesian cross and 364 Jersey cross) from all districts (n=11) of Meghalaya were assessed with the survey, clinical examination, and personal observations. Results: Out of the total animal assessed, 33.85% (n=195) were found to be affected with one or more of the clinical reproductive problems. Repeat breeding (RB), anestrus, retention of fetal membrane, and abortion were found to be the major clinical reproductive problems. Out of the total animal affected with reproductive disorders, the incidence of anestrus, RB, retention of fetal membrane, and abortion was found to be 31.79% (n=62), 24.61% (n=48), 14.35% (n=28), and 11.25% (n=22), respectively. In addition, dystocia (5.12%), prolapse (1.53%), endometritis (4.61%), and pyometra (6.66%) were minor clinical reproductive problems. There was a significant difference in the incidence of reproductive disorders with respect to breed, age, and parity. Conclusion: It was revealed from this study that RB, anestrus, retention of fetal membrane, and dystocia are the major clinical reproductive problems in Meghalaya. Results indicated unsatisfactory feeding, housing, and health management practices are the main cause of low fertility of dairy cows. Lack of scientific knowledge, low access to breeding, and health services further contributed to low productivity and fertility. PMID:27284229

    Central nervous system (CNS) involvement is a known complication of scrub typhus which range from mild meningitis to frank meninigoencephalitis. Aims and objectives: To study the clinical feature, laboratory parameters and response to treatment of scrub typhus meningitis/meningoencephalitis. Methods and Materials: This is a hospital based prospective observational study from North Eastern India. Diagnosis was based on clinical features and positive serological test (Weil's Felix test and IgM antibody card test). Results: 13 patients of scrub typhus with features of meningitis/meningoencephalitis were included. The mean duration of fever before presentation was 5.61±3.08 days and 4 (30.76 %) patients had eschar. Altered sensorium, headache, seizure and meningeal sign were present in 13 (100%), 13 (100%), 6 (46.15%) and 10 (76.92%) patients respectively. Mean CSF protein, glucose and Adenosine deaminase was 152.16±16.88mg/dl, 55.23±21.7mg/dl, and 16.98±7.37U/L respectively. Mean total count of CSF leukocyte and lymphocyte percentage was 46.07±131 cell/cumm and 98.66±3.09% respectively. Tablet doxycycline with or without injection azithromycin was used and that shows good response 15.38% of patients died and all of them had multi organ dysfunction. Conclusion: Meningoencephalitis is a common manifestation of scrub typhus and diagnosis requires high degree of clinical suspicion which if diagnosed early and specific treatment started, patients usually recover completely with few complications.

    Intra-seasonal and inter-annual variability of Bowen Ratio (BR) have been studied over the rain-shadow region of north peninsular India during summer monsoon season. Daily grid point data of latent heat flux (LHF), sensible heat flux (SHF) from NCEP/NCAR Reanalysis for the period 1970-2014 have been used to compute daily area-mean BR. Daily grid point rainfall data at a resolution of 0.25° × 0.25° from APHRODITE's Water Resources for the available period 1970-2007 have been used to study the association between rainfall and BR. The study revealed that BR rapidly decreases from 4.1 to 0.29 in the month of June and then remains nearly constant at the same value (≤0.1) in the rest of the season. High values of BR in the first half of June are indicative of intense thermals and convective clouds with higher bases. Low values of BR from July to September period are indicative of weak thermals and convective clouds with lower bases. Intra-seasonal and inter-annual variability of BR is found to be inversely related to precipitation over the region. BR analysis indicates that the land surface characteristics of the study region during July-September are similar to that over oceanic regions as far as intensity of thermals and associated cloud microphysical properties are concerned. Similar variation of BR is found in El Nino and La Nina years. During June, an increasing trend is observed in SHF and BR and decreasing trend in LHF from 1976 to 2014. Increasing trend in the SHF is statistically significant.

    Trend analysis of hydro-climatic variables such as streamflow, rainfall, and temperature provides useful information for effective water resources planning, designing, and management. Trends in observed streamflow at four gauging stations in the Gomti River basin of North India were assessed using the Mann-Kendall and Sen's slope for the 1982 to 2012 period. The relationships between trends in streamflow and rainfall were studied by correlation analyses. There was a gradual decreasing trend of annual, monsoonal, and winter seasonal streamflow ( p < 0.05) from the midstream to the downstream of the river and also a decreasing trend of annual streamflow for the 5-year moving averaged standardized anomalies of streamflow for the entire basin. The declining trend in the streamflow was attributed partly to the increased water withdrawal, to increased air temperature, to higher population, and partly to significant reducing trend of post monsoon rainfall especially at downstream. Upstream gauging station showed a significant increasing trend of streamflow (1.6 m3/s/year) at annual scale, and this trend was attributed to the significant increasing trend of catchment rainfall (9.54 mm/year). It was further evident in the significant coefficient of positive correlation ( ρ = 0.8) between streamflow and catchment rainfall. The decreasing trend in streamflow and post-monsoon rainfall especially towards downstream area with concurrent increasing trend of temperature indicates a drying tendency of the Gomti River basin over the study period. The results of this study may help stakeholders to design streamflow restoration strategies for sustainable water management planning of the Gomti River basin.

Interpretation & conclusions: Our results showed that fluoroquinolone resistance in enterococcal UTI was largely associated with indoor usage of antibiotics and use of indwelling devices. Knowledge of risk factors is important to curb this emergence of resistance. PMID:28256471

    Dust storms mark a major natural event in north India which loads the atmosphere with enormousamount of aerosols. Thus, this study aimed at tracking the key features of aerosol composition,particularly on the days of major dust storms, along the trajectory of dust storms in the Indianregion. Dustfall was monitored at five sites, with important geological locations, in the northwesternregion from April to June, 2015. The dustfall flux was the highest at western most sites of Jaipur(JP) (1206 mg/m2/day) and Bikaner (BK) (516.3 mg/m2/day). These sites not only mark the entrypoint of dust storms from middle east and African regions but also are surrounded by the IndianThar desert, as seen in the NOAA HYSPLIT model trajectories during dust storm period.Interestingly, Ca fluxes varied in accordance with the dustfall fluxes which were also found to bethe highest at JP (87.9 mg/m2/day) followed by BK (59.1 mg/m2/day). The variation of Ca fluxfurther matched well with the pattern of SO42- flux, where again JP (11.9mg/m2/day) recorded thehighest value followed by BK (9.5mg/m2/day). This is indicative of the scavenging of the SO42- byCa present in the resuspended dust.The following eastward sites of Hisar (HS), the capital city ofDelhi (DL) and Agra (AG) represent a shift of geology and also the source of aerosols as are urbancentres. These urban centres, on the other hand recorded the fluxes of NO3- ( DL - 0.9 mg/m2/day)and F- (HS - .1 mg/ m2/day). These findings shed light on the nature of chemical composition ofaerosols from dust, along the trajectory of dust storms in the northwestern region of Indian.

    Summary Background To diagnose and characterize the perianal fistulous disease using Magnetic resonance imaging (MRI) in a hilly and rural area of North India. Material/Methods This prospective hospital based study was conducted for a period of one year from April 2014 to April 2015 in the departments of Radiodiagnosis and Surgery of our institute. A total of 50 consecutive patients presenting with perianal fistulous disease fulfilling the inclusion and exclusion criteria were included in the study and taken up for MRI. The perianal fistulae were classified according to St James University hospital classification and tracks were assessed with regard to anatomical plane, length, ramifications, abscess formation, enteric communication, external cutaneous opening, enhancement and suprasphincteric extension. Surgical correlation was done in 31 patients who opted for surgical treatment. Rest of the 19 patients preferred alternative medicine for treatment or chose to postpone their surgery. Results The disease was much more prevalent in males in comparison to females with male to female ratio of 24:1. Grade 4 was the most common type of fistula (34%) while Grade 5 was the least common type (4%).MRI showed a high sensitivity of 93.7% and positive predictive value (PPV) of 96.7% when correlated with surgical findings. A substantial number of patients (38%) preferred alternative medicine or non surgical form of treatment. Conclusions MRI is a very sensitive modality for the evaluation of perianal fistula. In our study group, the disease predominantly affected middle aged men. Ramifications and abscesses were commonly seen, affecting nearly half of the patients and majority of the patients had active fistulous tracks with posteriorly located enteric opening. Overall, transsphincteric fistulae were most common. Significant number of patients avoided surgery or showed preference for non surgical treatment. PMID:28096904

    As part of national program, laboratory supported vaccine preventable diseases surveillance was initiated in Kerala in 2015. Mechanisms have been strengthened for case investigation, reporting, and data management. Specimens collected and sent to state and reference laboratories for confirmation and molecular surveillance. The major objective of this study is to understand the epidemiological information generated through surveillance system and its utilization for action. Surveillance data captured from reporting register, case investigation forms, and laboratory reports was analyzed. Cases were allotted unique ID and no personal identifying information was used for analysis. Throat swabs were collected from investigated cases as part of surveillance system. All Corynebacterium diphtheriae isolates were confirmed with standard biochemical tests, ELEK's test, and real-time PCR. Isolates were characterized using whole genome-based multi locus sequence typing method. Case investigation forms and laboratory results were recorded electronically. Public health response by government was also reviewed. A total of 533 cases were identified in 11 districts of Kerala in 2016, of which 92% occurred in 3 districts of north Kerala; Malappuram, Kozhikode, and Kannur. Almost 79% cases occurred in >10 years age group. In <18 years age group, 62% were male while in ≥18 years, 69% were females. In <10 years age group, 31% children had received three doses of diphtheria vaccine, whereas in ≥10 years, 3% cases had received all doses. Fifteen toxigenic C. diphtheriae isolates represented 6 novel sequence types (STs) (ST-405, ST-408, ST-466, ST-468, ST-469, and ST-470). Other STs observed are ST-50, ST-295, and ST-377. Diphtheria being an emerging pathogen, establishing quality surveillance for providing real-time information on disease occurrence and mortality is imperative. The epidemiological data thus generated was used for targeted interventions and to formulate

    Forest fires are a major environmental problem in North East Region (NER) with large tracts of forest areas being affected in every season. Forest fires have become a major threat to the forest ecosystems in the region, leading to loss of timber, biodiversity, wildlife habitat and loss to other natural resources. Studies on forest fire have reported that about 50% of forest fire in the country takes place in NE region. The forest fire in NER is anthropogenic in nature. The forest fire hazard map generated based on appropriate weightage given to the factors affecting fire behavior like topography, fuel characteristic and proximity to roads, settlements and also historical fire locations helped to demarcate the fire prone zones. Whereas, during fire season the weather pattern also governs the fire spread in the given area. Therefore, various data on fuel characteristics (land use/land cover, forest type map, forest density map), topography (DEM, slope, aspect) proximity to settlement, road, waterbodies, meteorological data from AWS on wind speed, wind direction, dew point have been used for each fire point to rank its possible hazard level. Near real time fire location data obtained from MODIS/FIRMSwere used to generate the fire alerts. This work demonstrates dissemination of information in the form of maps and tables containing information of latitude and longitude of fire location, fire occurrence date, state and district name, LULC, road connectivity, slope and aspect, settlements/water bodies and meteorological data and the corresponding rating of possibility of fire spread to the respective fire control authorities during fire season.

    BACKGROUND Breast cancer is one of the most common malignancies in women and is associated with a variety of risk factors. The functional single-nucleotide polymorphism (SNP) C677T in the gene encoding 5,10-methylenetetrahydrofolate reductase (MTHFR) may lead to decreased enzyme activity and affect the chemosensitivity of tumor cells. This study was designed to investigate the association of MTHFR gene polymorphism (SNP) in the pathogenesis of breast cancer among the North Indian women population. MATERIALS AND METHODS Genotyping was performed by polymerase chain reaction (PCR) using genomic DNA, extracted from the peripheral blood of subjects with (275 cases) or without (275 controls) breast cancer. Restriction fragment length polymorphism was used to study C677T polymorphism in the study groups. RESULTS The distribution of MTHFR (C677T) genotype frequencies, ie, CC, TT, and CT, among the patients was 64.7%, 2.18%, and 33.09%, respectively. In the healthy control group, the CC, TT, and CT frequencies were 78.91%, 1.09%, and 20.1%, respectively. The frequencies of C and T alleles were 81.2% and 18.7%, respectively, in the patient subjects, while they were 88.9% and 11.09%, respectively, among the healthy control group. Frequencies of the CT genotype and the T allele were significantly different (P = 0.007 and P = 0.005, respectively) between the control and the case subjects. CONCLUSION This study shows an association of the CT genotype and the T allele of the MTHFR (C667T) gene with increased genetic risk for breast cancer among Indian women. PMID:27721657

  8. Generation of buckle folds in Naga fold thrust belt, north-east India

    2009-04-01

    Naga fold thrust belt (NFTB), India, formed as a result of northward migration of the Indian plate initiated in Eocene and its subsequent collision with the Burmese plate during Oligocene. The NW-SE oriented compression generated a spectrum of structures; among them, we intend to focus on the folds- varying from gentle to tight asymmetric in geometry. Large recumbent folds are often associated with thrusting. Buckle folds forming under shallow crustal conditions are frequently reported from NFTB. Buckle folding occurs mainly within sandstones with intercalated shale layers which are in the study area typical for the Barail, Surma and Tipam Groups. We have tried to explain the controlling factors behind the variation of the buckle fold shapes and their varying wavelengths throughout the fold thrust belt with the aid of analogue (sand box) modelling. It is undoubted that competence contrast along with the layer parallel compressive stress are the major influencing factors in generation of buckle folds. Schmalholz and Podladchikov (1999) and Jeng et al. (2002) have shown that when low strain rate and low temperature are applicable, not only the viscosity contrast, but also the elasticity contrast govern the geometry of the developing buckle folds. Rocks deforming under high temperature and high pressure deform in pure viscous manner, whereas, rocks undergoing less confining stress and less temperature, are subjected to pure elastic deformation. However, they are the end members, and most of the deformations are a combination of these two end members, i.e. of viscoelastic nature. Our models are made up of sieved sand (0.5 mm grain size) and mica layers (1-5 mm) This interlayering imparts a mechanical anisotropy in the model. Mica is not a pure viscous material, rather it displays more elastic behaviour. The mica layers in the model produce bedding parallel slip during shortening through internal reorganization of the individual mica crystals leading to the thickening

    Natural and human causes of change in land use on soil carbon were studied at the outlet of the Tista River from the Sikkim Himalayas over the last 150 years. Analysis of topographic maps and satellite images indicates that the land reforms related to location of tea gardens in the piedmont caused rapid deforestation of terraces in the late 19th century. Continuous population growth after 1930 initiated the replacement of floodplain forest by rice cultivation. Both processes changed soil carbon content and intensified fluvial activity expressed through terrace erosion. The replacement of natural forest by tea cultivation reduced the soil carbon content within terraces from 1.95 kg to 1.77 kg (in 1 m of topsoil) respectively. The replacement of natural forest by rice reduced the soil carbon content within floodplains from 0.42 kg to 0.23 kg (in 1 m topsoil) respectively. Much more dangerous, was terrace erosion leading to permanent removal of sediment including soil. The total loss of soil carbon in a 1 m thick soil layer due to conversion of 5 km2 forest to tea cultivation was about 900 t between 1930 and 2010. While the total soil carbon removed due to 1.8 km2 terrace erosion reached 3510 t in the same period. Result is the outcome of research project 2012/05/B/ST10/00309 of the National Science Centre (Poland).

    The Daling Thrust (DT) delineates a zone of intense shear localization in the Lesser Himalayan Sequence (LHS) of the Darjeeling-Sikkim Himalaya. From microstructural studies of deformed quartzite samples, we show a transition in the dynamic recrystallization mechanism with increasing distance from the DT, dominated by grain boundary bulging (BLG) recrystallization closest to the DT, and progressively replaced by sub-grain rotation (SGR) recrystallization away from the thrust. The transition is marked by a characteristic variation in the fractal dimension (D) of grain boundaries, estimated from the area-perimeter method. For the BLG regime, D ≈ 1.046, which decreases significantly to a value as low as 1.025 for the SGR regime. Using the available thermal data for BLG and SGR recrystallization, we infer increasing deformation temperatures away from the DT in the hanging wall. Based on the quartz piezometer our estimates reveal strong variations in the flow stress (59.00 MPa to 16.00 MPa) over a distance of ~ 1.2 km from the DT. Deformation mechanism maps constructed for different temperatures indicate that the strain rates (10- 12 S- 1 to 10- 14 S- 1) comply with the geologically possible range. Finally, we present a mechanical model to provide a possible explanation for the cause of stress intensification along the DT.

    This observational study during the 29-year period from 1979 to 2007 evaluates the potential role of Eurasian snow in modulating the North East-Indian Summer Monsoon Rainfall with a lead time of almost 6 months. This link is manifested by the changes in high-latitude atmospheric winter snow variability over Eurasia associated with Arctic Oscillation (AO). Excessive wintertime Eurasian snow leads to an anomalous cooling of the overlying atmosphere and is associated with the negative mode of AO, inducing a meridional wave-train descending over the tropical north Atlantic and is associated with cooling of this region. Once the cold anomalies are established over the tropical Atlantic, it persists up to the following summer leading to an anomalous zonal wave-train further inducing a descending branch over NE-India resulting in weak summer monsoon rainfall.

    Background & objectives: The indiscriminate use of third generation cephalosporin has contributed to the emergence and widespread dissemination of extended spectrum β lactamases (ESBL) genes in Klebsiella pneumoniae. This study was undertaken to elaborate the genetic behaviour of ESBL - producing K. pneumoniae isolates in the neonatal intensive care unit (NICU) of a tertiary care hospital in north India causing successive outbreaks in context with empirical third generation cephalosporin use. Methods: Isolates of K. pneumoniae (43 from blood, 3 from pus and endotracheal tube, 4 from environment) causing successive outbreaks in the NICU of a tertiary care university hospital were studied for two years. Antimicrobial susceptibility testing was done by disc diffusion and minimum inhibitory concentration (MIC) determination by agar dilution methods. ESBL production was determined by phenotypic and genotypic methods. Clonal relatedness among the isolates was studied by enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR). Genetic environment of these isolates was assessed by the presence of integrons and gene cassettes. Transformation experiments were done, and plasmids of these isolates were characterized by stability testing and incompatibility testing. Subsequently, a change in the ongoing antibiotic policy was adopted, and corresponding changes in the behaviour of these isolates studied. Results: During the period from August 2011 to January 2013, 46 isolates of monoclonal ESBL K. pneumoniae were obtained from different neonates and four similar environmental isolates were studied. Multidrug-resistant ESBL isolates harboured both blaCTXM-15 and blaSHV-5. The dfr and aac-6’ resistant genes were found in gene cassettes. A 50 kb plasmid belonging to IncFIIA group was detected in all the isolates which was transferable and stable. The emergence and regression of the outbreaks coincided with antibiotic usage in the NICU, with widespread

    Background: Research into substance use disorders (SUD) has been unable to unequivocally demonstrate effectiveness of treatment modalities. Aims: The aim of the study was to study the long-term outcome after in-patient treatment in a cohort of patients admitted for SUD in a deaddiction unit of a hospital in North India. Materials and Methods: The case notes of all in-patients with a primary diagnosis of alcohol and/or opioid dependence syndrome (F10.24 and F11.24) in the calendar year 2006 were examined. All patients without any physical or mental comorbidity other than comorbid SUD were included in the study. They were contacted telephonically or their case notes examined in September, 2007. Status regarding abstinence or relapse was determined and data was analyzed. Independent samples t-test and chi-square test were used for determining significance of difference between continuous and categorical variables respectively. Kaplan-Meier analysis was applied to find the survival times of different groups with the duration to relapse as variable of interest. Log rank test was applied to find the significance of differences in various groups. Cox's Regression analysis was applied to find the hazard ratio. Results and Conclusions: Data for 59.22% of patients included in the study were available for analysis. Mean survival time was 36.35 weeks (28.74-43.95, 95% CI) for patients across different groups, 36.71 weeks (26.24-47.18, 95% CI) for the alcohol group, 34.00 weeks (8.37-59.36, 95% CI) for natural opioids group, 37.53 weeks (26.33-48.73, 95% CI) for semi/synthetic opioids group and 17.00 weeks (3.39-30.60, 95% CI) for the mixed group. Kaplan-Meier analysis revealed that those who were following-up at time of evaluation had significantly longer durations to relapse. Deaddiction services should stress on keeping patients on follow-up as a means to better outcomes. PMID:19823613

    Recent advances in genetic screening have ushered in a new era in diagnosis and management of medullary thyroid cancer (MTC). However, the same is not true for a resource-poor country, where clinicians are still struggling to diagnose and adequately manage this relatively uncommon thyroid malignancy. We hereby present our experience of managing MTC at a tertiary care referral center in North India. This was a retrospective study conducted between January 1990 and July 2009. Demographics, clinical profiles, details of surgical procedures, and follow-up records were reviewed. A total of 71 patients with MTC were identified. Mean age of this group was 39.9±14.1 years, and men outnumbered women 1.7:1. Some 84.5% of patients had seemingly sporadic MTC, and 15.5% had familial MTC (MEN2a=14.1%, MEN 2b=1.4%). All patients had a thyroid nodule at the time of presentation. Mean tumor diameter was 4.9 cm. Cervical lymphadenopathy, mediastinal lymphadenopathy, extrathyroidal invasion, and distant metastases were present in 59%, 7.2%, 10%, and 4.2% of patients, respectively. Staging showed that 4.8% of patients were stage I, 17.5% stage II, 14.3% stage III, and 63.6% stage IV. Treatment was as follows: 92.6% of patients had total thyroidectomy (primary or secondary); 67.6% central compartment lymph node dissection, 62.3% lateral cervical lymph node dissection, and 7.2% trans-sternal mediastinal lymph node dissection performed. Some 66.7% of patients suffered from persistent hypercalcitoninemia, and 11.4% of those underwent reoperation. The 5-year and 10-year overall survival (OS) was 74.6% and 58%, respectively. The majority of the patients with MTC presented at stage IVa, contributing to the high rate of persistent hypercalcitoninemia. Despite a policy of observation and intervening only in overtly symptomatic patients with persistent hypercalcitoninemia, overall survival (OS) in our study was comparable to other series, reinforcing the belief that persistent

    Limitation over region specific data on dust morphology (particle shape, size) and mineralogy gives rise to uncertainty in estimation of optical and radiative properties of mineral dust (Mishra and Tripathi, 2008; Mishra et al., 2008). To address this issue over Indian arid zone (local source of mineral dust), a short field campaign was organized in Jodhpur, located in Rajasthan, a north western state of India, over seven sites (four in city and three far from city) with varying altitudes in June 2013. Jodhpur lies in vicinity of the Thar Desert of Rajasthan. Particles were collected on pure Tin substrates for individual particle morphological and elemental composition analysis using Scanning Electron Microscope (SEM) equipped with Energy Dispersive Spectrometer (EDS). The morphological parameters (e.g. Aspect ratio; AR, Circulatory parameter; CIR.) were retrieved following Okada et al. (2001) using Image J software. Columnar spectral aerosol optical thickness has been measured by Microtops-II sun photometer for a set of five wavelengths (380 to 1020 nm) over all the sites in tandem with regional aerosol collection. SEM analysis reveals that the particles close to spherical shape (AR range 1.0-1.2) were found to be ~ 18% whereas particles with AR range 1.2-1.4 were found to be abundant (25%) followed with that of AR range 1.4-1.6 and 1.6-1.8 (each ~ 17%) and 1.8-2.0 (~ 14%) while the particles with AR >2 (highly non-spherical) were found to be ~ 8%. Here, it is noteworthy to mention that AR=1 for spherical particle while increasing AR (>1) exhibit increasing non-sphericity of particles. The EDS analysis reveals that 43% particles were observed with low hematite (H ≤ 1%; volume percentage), 24% (H 1-2 %), 14% (H 2-3%), 5% (H 3-4%) and 14% (H >4%). The aforementioned proportions will be extremely useful for simulating the optical and radiative properties of regional aerosols. From the Microtops-II observations, Ångström exponent for spectral interval of 380 to

    Pseudomonas aeruginosa is one of the leading opportunistic pathogen and its ability to acquire resistance against series of antimicrobial agents confine treatment option for nosocomial infections. Increasing resistance to fluroquinolone (FQ) agents has further worsened the scenario. The major mechanism of resistance to FQs includes mutation in FQs target genes in bacteria (DNA gyrase and/or topoisomerases) and overexpression of antibiotic efflux pumps. We have investigated the role of efflux pump mediated FQ resistance in nosocomial isolates of P. aeruginosa from a tertiary referral hospital in north eastern part of India. A total of 234 non-duplicate, consecutive clinical isolates of P. aeruginosa were obtained from a tertiary referral hospital of north-east India. An efflux pump inhibitor (EPI), carbonyl cyanide m-chlorophenylhydrazone (CCCP) based method was used for determination of efflux pump activity and multiplex polymerase chain reaction (PCR) was performed for molecular characterisation of efflux pump. Minimum inhibitory concentration (MIC) reduction assay was also performed for all the isolates. A total number of 56 (23%) have shown efflux mediated FQ resistance. MexAB-OprM efflux system was predominant type. This is the first report of efflux pump mediated FQ resistance from this part of the world and the continued emergence of these mutants with such high MIC range from this part of the world demands serious awareness, diagnostic intervention, and proper therapeutic option.

    Identifying with a group can contribute to a sense of well-being. The mechanisms involved are diverse: social identification with a group can impact individuals' beliefs about issues such as their connections with others, the availability of social support, the meaningfulness of existence, and the continuity of their identity. Yet, there seems to be a common theme to these mechanisms: identification with a group encourages the belief that one can cope with the stressors one faces (which is associated with better well-being). Our research investigated the relationship between identification, beliefs about coping, and well-being in a survey (N = 792) administered in rural North India. Using structural equation modelling, we found that social identification as a Hindu had positive and indirect associations with three measures of well-being through the belief that one can cope with everyday stressors. We also found residual associations between participants' social identification as a Hindu and two measures of well-being in which higher identification was associated with poorer well-being. We discuss these findings and their implication for understanding the relationship between social identification (especially with large-scale group memberships) and well-being. We also discuss the application of social psychological theory developed in the urban West to rural north India. © 2014 The Authors.

    In present pilot study aimed to estimate, presence of Mycobacterium avium subspecies paratuberculosis (MAP) antibodies in the human serum samples originating from North India using "Indigenous absorbed ELISA kit" (ELISA kit). The phase I, "ELISA kit" was optimized using protoplasmic antigen from native isolate of MAP "Indian Bison type" recovered from the biopsies of Crohn's disease patients. The phase II, sensitivity and specificity of the kit were estimated as 40.0 and 83.3%, respectively, when evaluated in 40 human serum samples (5 Crohn's disease and 22 ulcerative colitis patients and 13 healthy human subjects) with defined MAP status with respect to stool culture. Seroprevalence of MAP antibodies was higher in CD patients (80.0%) as compared to ulcerative colitis patients (4.5%) and normal human subjects (15.3%). The phase III, seroprevalence of MAP antibodies was estimated as 23.4%, on the basis of the screening of 452 human serum samples (without history) from different geographical regions of North India. Region-wise, 34.0, 33.3, 32.8, 25.0, 23.0, 17.7, and 12.5% samples were positive from the states of Punjab, Uttarakhand, New Delhi, Himachal Pradesh, Haryana, Uttar Pradesh and Jammu and Kashmir, respectively. Study reported moderately higher presence of MAP antibodies in human population, which necessitates programs to reduce the bioburden of MAP in the environment and in animal population.

    Compliance survey of smoke-free law is an effective means of measuring progress towards a smoke-free society. They also help policy makers to take action where strengthening measures are required. India has a comprehensive tobacco control law known as Cigarettes and Other Tobacco Products Act (COTPA 2003) which prohibits smoking in public places and requires display of 'No smoking' signages with proper specifications at conspicuous points. However, its implementation and enforcement are still a matter of concern. To ascertain the level of compliance with smoke-free law in public places of a district of North India. A cross sectional study was conducted in the months of November-December 2011 in district SAS Nagar Mohali of North India. The public places including hotels/restaurants/bars/shopping malls, government offices, educational institutions, healthcare facilities and transit stations were surveyed. The study tool was adapted from the guide on 'Assessing compliance with smoke-free law' developed jointly by the Campaign for Tobacco Free Kids, Johns Hopkins Bloomberg School of Public Health and International Union against Tuberculosis and Lung Disease. The overall compliance rate towards section 4 of COTPA was 92.3%. No active smoking was observed in 94.2% of the public places. In 90% of the public places 'No Smoking' signage were displayed as per COTPA. Health and educational institutions had maximum compliance with the smoke-free law while transit sites showed the least compliance. Compliance to the smoke-free law was high in the study.

    Neural tube defects (NTDs) are one of the commonest birth defects. There was paucity of community-based data on occurrence of NTDs in India, especially from rural parts of the country. Against this background, the current study was carried out with main objectives to determine the prevalence of NTDs and its specific types (anencephaly, spina bifida and encephalocele) in a rural community setting over the time period 2001 to 2014. This was a community-based cross-sectional study carried out in 28 villages of Ballabgarh Tehsil of Faridabad district in north India (population ∼ 96,000). A household survey was undertaken by trained multi-purpose workers who enquired ever-married women about history of conception with outcome as NTD during the study period. The probable case of NTD was determined using a colored pictorial card with photographs of different types of NTDs. These cases were confirmed by doctors. A total of 26,946 live births occurred during the years 2001 to 2014. A total of 140 confirmed cases of NTDs were identified. The live birth prevalence of NTDs was 24.1 per 10,000 live births (95% confidence interval, 18.8-30.6). The birth prevalence of NTDs for the years 2008 to 2014 was 50.8 (95% confidence interval, 39.9-63.8) per 10,000 live and stillbirths. The most common type of NTD was found to be spina bifida followed by anencephaly and encephalocele. We found high prevalence of NTDs in rural community settings from north India for years 2001 to 2014.Birth Defects Research 109:203-210, 2017.© 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    The hereditary hemoglobin (Hb) disorders are the most commonly encountered single gene disorders in India. Data pertaining to the pattern of hemoglobinopathies and thalassemias is scarce in North East India, and hence it was considered worthwhile to study these disorders using a large series of patients referred to a clinical diagnostic laboratory. A total of 9000 patients referred for Hb variant analysis were studied to identify hemoglobinopathies and thalassemias in Upper Assam region of North East India. This study was performed by high performance liquid chromatography (HPLC) using BIORAD variant Hb typing system. Out of 9000 patients studied, abnormal Hb fractions were seen in 5320 patients. The HbE gene was detected in 4315 patients of which HbE trait was seen in 2294 followed by HbE disease in 1892. There were 114 HbE beta thalassemia patients and 15 double heterozygotes of HbE with HbS or HbD. Beta thalassemia trait was seen in 313 patients and beta thalassemia homozygous in 32. HbS gene was detected in 460 patients comprising of HbS trait in 189, HbS disease in 203, S beta thalassemia in 53 and double heterozygotes of SD and ES in 15. The rest comprised of HbD trait in 6, delta beta thalassemia in 33, hereditary persistence of fetal hemoglobin trait in 5 and J chain hemoglobinopathy in 8 patients. Evidence of alpha thalassemia though suspected, could not be confirmed. A high incidence of hemoglobinopathies and thalassemias and their combinations is unique for this part of the country.

    Introduction: Nasopharyngeal carcinoma (NPC) is a common cancer in the North-East region of India. Though the role of environmental contributors of NPC in the North-Eastern part of India is firmly established, EBV as an etiological agent in the region remains unexplored. Material and Methods: Fifty-one patients, who presented at the department of ENT, NEIGRIHMS and were confirmed as NPC upon histopathological examination, were included in the study. Chromogenic in-situ hybridization (CISH) was used for the evaluation of EBER (Epstein Barr Virus Encoded RNA). Presence of nuclear signals was taken as positive for EBER expression. EBER status was correlated with various clinicopathological parameters like age, sex, dietary habits, histological types of NPC, and ethnicity of the patients. Results: The age range of the study group was 25 to 70 years with a mean age of 44.64 years and a male:female ratio of 3:2. Non-keratinizing undifferentiated type of NPC was the most common histological type. EBV was positive in 59% (30/51) of our cases. It showed a statistically significant correlation with the Naga community (P=0.01), with consumption of smoked food (P=0.02), and cigarette smoking (P=0.02). There was no correlation of EBV with age, sex, lymph node metastasis, stage, and histology. Conclusion: Our result indicates that EBV may be an additional risk factor in the pathogenesis of NPC in this region of India. So apart from lifestyle modification, a future study for a screening test for EBV viral load even in asymptomatic patients may be considered, for determination of disease susceptibility, early diagnosis, and proper management.

    Background: Contamination of water, food, and environment with antibiotic-resistant bacteria poses a serious public health issue. Objective: The objective was to study the bacterial pollution of the natural sources of water in east Sikkim and to determine the antimicrobial profile of the bacterial isolates. Materials and Methods: A total of 225 samples, 75 each during winter, summer, and monsoon season were collected from the same source in every season for bacteriological analysis by membrane filtration method. Antibiotic susceptibility test was performed using standard disc diffusion method. Results: A total of 19 bacterial species of the genera Escherichia, Klebsiella, Proteus, Salmonella, Shigella, Enterobacter, Citrobacter, Morganella, Pseudomonas, Acinetobacter, Flavobacterium, and Serratia were isolated and their antimicrobial sensitivity tested. Generally, most bacterial isolates except Salmonella and Shigella species were found resistant to commonly used antibiotics such as ampicillin (57.5%), trimethoprim/sulfamethoxaole (39.1%), amoxicillin/clavulanic acid (37.4%), cefixime (34.5%), tetracycline (29.1%), ceftazidime (26.3%), ofloxacin (25.9%), amikacin (8.7%), and gentamicin (2.7%) but sensitive to imipenem and piperacillin/tazobactam. Conclusion: Natural sources of water in east Sikkim are grossly contaminated with bacteria including enteropathogens. The consumption of untreated water from these sources might pose health risk to consumers. PMID:25136156

    Dopamine D2 receptor (DRD2) is one of the essential neurotransmitters in the brain studied extensively in the field of psychiatric disorders, alcoholic behaviors and Pharmacology. It is also a promising gene for studying the evolutionary and genetic variation among populations. The present study was an attempt to understand the extent of genetic variation among five different ethnic groups (Bania, Brahmin, Jat Sikh, Khatri and Scheduled caste) of Punjab (North West India). A total of 1012 individuals belonging to the above mentioned groups were analyzed for three TaqI Polymorphic loci of DRD2 and ankyrin repeat and kinase domain containing 1 (ANKKI) using the allele frequencies and haplotype frequency distribution pattern. All the three loci were found to be polymorphic among the studied populations. The average heterozygosity for all loci in these ethnic groups was fairly substantial ranging from 0.3936 to 0.4986. The genetic differentiation among the population was observed to be in order of 0.0053.Among of the eight studied haplotypes, only six were shared by all the ethnic groups. TaqID and TaqIB loci were reported to be in significantly higher linkage disequilibrium (LD) in Scheduled Caste only, whereas TaqIA and TaqID showed modest LD in Brahmin, Jat Sikh and Khatri. Multidimensional scaling analysis revealed that the studied ethnic groups formed a close cluster, suggesting similar genetic structure of these populations which are in close proximity with other Indo European speaking North Indian and western Indian population groups. Overall this study highlights the genomic uniformity among the ethnic groups of Punjab (North-West India) owing to their common ancestral history and geographical closeness. Copyright © 2016.

    The transformation of palaeo-continents involve breakup, dispersal and reassembly of cratonic blocks by collisional suturing that develop a network of orogenic (mobile) belts around the periphery of the stable cratons. The nature of deformation in the orogenic belt depends on the complex interaction of fracturing, plastic deformation and diffusive mass transfer. Additionally, the degree and amount of melting during regional deformation is critical as the presence of melt facilitates the rate of diffusive mass transfer and weakens the rock by reducing the effective viscosity of the deformed zone. The nature of strain localization and formation of ductile shear zones surrounding the cratonic blocks have been correlated with Proterozoic-Palaeozoic supercontinent assembly (Columbia, Rodinia and Gondwana reconstruction). Although, a pre-Columbia supercontinent termed as Kenorland has been postulated, there is no evidence that supports the notion due to lack of the presence of shear zones within the Archaean cratonic blocks. In this contribution, we present the detailed structural analysis of ductile shear zones within the Bundelkhand craton. The ductlile shear zone is termed as Bundelkhand Tectonic Zone (BTZ) that extends east-west for nearly 300 km throughout the craton with a width of two-three kilometer . In the north-central India, the Bundelkhand craton is exposed over an area of 26,000 sq. The craton is bounded by Central Indian Tectonic zone in the south, the Great Boundary fault in the west and by the rocks of Lesser Himalaya in the north. A series of tonalite-trondjhemite-granodiorite gneiss are the oldest rocks of the Bundelkhand craton that also contains a succession of metamorphosed supracrustal rocks comprising of banded iron formation, quartzite, calc-silicate and ultramafic rocks. K-feldspar bearing granites intrude the tonalite-trondjhemite-granodiorite and the supracrustal rocks during the time span of 2.1 to 2.5 Ga. The TTGs near Babina, in central

    Background Statistics show an increasing proportion of alcohol and drug use in drivers in more recent times throughout the world. It has been found that among the various human factors, alcohol consumption, using drugs and subsequent driving on the roads are major risk factors. Traffic regulations in India penalises drivers who drive beyond permissible alcohol limit of 30 mg%. Consumption of psychoactive drugs such as opioid, cannabis and benzodiazepines has been reported mainly among youngsters. Hardly any data is available in Indian context particularly from North-West Zone of India. Study objective To study the pattern of alcohol, opioid, cannabis and benzodiazepines use in injured drivers presenting to a designated trauma centre in Chandigarh zone of North-West India. Materials and Methods Consenting injured drivers who presented to the trauma centre in Chandigarh from September 2013 to January 2014 were included. Urine samples collected from the subjects were screened for abusive drug exposure (opioid, cannabis and benzodiazepines) and alcohol using commercial bedside urine immunoassay kits. In urine alcohol positive cases blood samples were collected and analysed for alcohol concentration using standard gas chromatography. Retrograde extrapolation method was used to assess BAC at the time of accident. Results A total of 200 injured drivers were included in this study. We found substance consumption in 54.5% of drivers and alcohol (40.5%) was the most prevalent substance consumed followed by opiates (13%), cannabis (7%) and benzodiazepines (7%). More than one substance was shown in urine of 11.5% of drivers. Among 81 alcohol positive screening cases, the quantitative analysis was successfully done for 76 cases. Except one, all cases showed BAC value more than 30 mg% which is the legal limit for driving any vehicle in India. The values of alcohol concentration in blood at the time of accident were in the range of 20 to 391 mg%. Conclusion This study has shown

    Background/Aims HBV has been classified into ten genotypes (A–J) and multiple subgenotypes, some of which strongly influence disease outcome and their distribution also correlate with human migration. HBV infection is highly prevalent in India and its diverse population provides an excellent opportunity to study the distinctiveness of HBV, its evolution and disease biology in variegated ethnic groups. The North-East India, having international frontiers on three sides, is one of the most ethnically and linguistically diverse region of the country. Given the paucity of information on molecular epidemiology of HBV in this region, the study aimed to carry out an in-depth genetic characterization of HBV prevailing in North-East state of Tripura. Methods From sera of chronically HBV infected patients biochemical/serological tests, HBV DNA quantification, PCR-amplification, sequencing of PreS/S or full-length HBV genomes were done. HBV genotype/subgenotype determination and sequence variability were assessed by MEGA5-software. The evolutionary divergence times of different HBV subgenotypes were estimated by DNAMLK/PHYLIP program while jpHMM method was used to detect any recombination event in HBV genomes. Results HBV genotypes D (89.5%), C (6.6%) and A (3.9%) were detected among chronic carriers. While all HBV/A and HBV/C isolates belonged to subgenotype-A1 and C1 respectively, five subgenotypes of HBV/D (D1–D5) were identified including the first detection of rare D4. These non-recombinant Indian D4 (IndD4) formed a distinct phylogenetic clade, had 2.7% nucleotide divergence and recent evolutionary radiation than other global D4. Ten unique amino acids and 9 novel nucleotide substitutions were identified as IndD4 signatures. All IndD4 carried T120 and R129 in ORF-S that may cause immune/vaccine/diagnostic escape and N128 in ORF-P, implicated as compensatory Lamivudine resistance mutation. Conclusions IndD4 has potential to undermine vaccination programs or anti

    Uranium (U) tolerant aerobic heterotrophs were isolated from the subsurface soils of one of the pre-mined U-rich deposits at Domiasiat located in the north-eastern part of India. On screening of genomic DNA from 62 isolates exhibiting superior U and heavy metal tolerance, 32 isolates were found to be positive for P(IB)-type ATPase genes. Phylogenetic incongruence and anomalous DNA base compositions revealed the acquisition of P(IB)-type ATPase genes by six isolates through horizontal gene transfer (HGT). Three of these instances of HGT appeared to have occurred at inter-phylum level and the other three instances indicated to have taken place at intra-phylum level. This study provides an insight into one of the possible survival strategies that bacteria might employ to adapt to environments rich in uranium and heavy metals.

    Background: Emergency Department (ED) of tertiary health care institute in India is mostly overcrowded, over utilized and inappropriately staffed. The challenges of overcrowded EDs and ill-managed patient flow and admission processes result in excessively long waits for patients. Aim: The objective of the present study was to analyze the patient flow system by assessing the arrival and waiting time distribution of patients in an Emergency out Patient Department (EOPD). Materials and Methods: This short cross-sectional descriptive study was conducted in the EOPD of a Tertiary level health care Institution in North India in the month of May, 2011. The data was obtained from 591 patients, who were present in the EOPD during the month of May, 2011. The waiting time, inter arrival time between two consecutive patients were calculated in addition to the daily census data (discharge rate, admission rate and transfer out rates etc.) of the emergency. Results: Arrival time pattern of patients in the EOPD was highly stochastic with the peak arrival hours to be 9.00-12.00 h in which around 26.3% patients arrived in the EOPD. The primary waiting areas of patients included patients under observation (29.6%); waiting for routine diagnostic tests (16.4%) and waiting for discharge (14.6%). Around 71% patients were waiting due to reasons within emergency complex. Conclusion: The patient flow of the ED could only be addressed by multifaceted, multidisciplinary and hospital wide approach.

    Population aging is a global phenomenon. In India, the size of the elderly population is growing fast. Many older adults have multiple medical conditions. Understanding elderly health problems and health-seeking behavior is prerequisite for proving comprehensive geriatric care to them. To assess the morbidity pattern and study the health-seeking behavior of the elderly people of Shimla district in Himachal Pradesh. A total of 400 elderly people aged 60 years and above were selected from urban and rural areas of Shimla hills in North India by simple random sampling. Statistical software Epi info software version 3.2 was used for analyzing data. Descriptive statistics were used to describe sociodemographic and morbidity variables. The most common morbidity identified among them were musculoskeletal problems (55.0%) followed by hypertension (40.5%). Two third were seeking treatment for their health problems. Among older persons not seeking treatment for their medical condition, most considered these morbidities as an age-related phenomenon. Many perceived that the health services were too far. The high morbidity load among elderly in the present study stresses for efforts to provide better health care to them and thus ensure that they remain active members of our society. Residence emerged out to be most significant determinant of healthcare-seeking behavior. Policy makers must focus on rural elderly and their beliefs which prevent them from seeking healthcare.

    Context: Oral squamous cell carcinoma (OSCC) is the most common malignancy in India and tobacco and betel nut chewing are well established risk factors. Despite successful campaigns to help people shun this habit in developing countries the incidence has rather gone up and HPV and sexual practices are now definitely implicated for this. Aim: An attempt was made to generate Indian data on role of HPV and sexual practices in relation to OSCC. Settings and Design: A prospective observational study was conducted on 50 patients with oral squamous cell carcinoma. Materials and Methods: Tissue biopsies from fifty patients of oral squamous cell carcinoma (OSCC) were subjected to PCR analysis to look for presence of HPV 16 and 18. Fifty patients with benign lesions were taken as control. Statistical Methods Used: The data was statistically analysed using SPSS version 22 and chi square test. Results: 42% of OSCC patients were found to harbour HPV 16 and 18 whereas only 8% of patients with benign lesions had HPV 16 and 18. A significant number of HPV positive patients i.e. 9 out of 21 gave history of multiple sexual partners and oral sex. Conclusions: This high percentage of HPV in OSCC in an Indian population from a tertiary care centre in north India and its association with prevailing sexual practices is quite significant.

    Bemisia tabaci is the major vector pest of agricultural crops all over the world. In this study we report the different bacterial endosymbionts associated with B. tabaci sampled from 14 different locations in North India. Using 16S rDNA clone library sequences we were able to identify Portiera, the primary endosymbiont of B. tabaci, and other secondary endosymbionts like Cardinium, Wolbachia, Rickettsia and Arsenophonus. Along with these we also detected Bacillus, Enterobacter, Paracoccus and Acinetobacter. These secondary endosymbionts were not uniformly distributed in all the locations. Phylogenetic analysis of 16S rDNA sequences of Cardinium, Wolbachia, Rickettsia and Arsenophonus showed that each of these bacteria form a separate cluster when compared to their respective counterparts from other parts of the world. MtCO1 gene based phylogenetic analysis showed the presence of Asia I and Asia II genetic groups of B. tabaci in N. India. The multiple correspondence analyses showed no correlation between the host genetic group and the endosymbiont diversity. These results suggest that the bacterial endosymbiont diversity of B. tabaci is much larger and complex than previously perceived and probably N. Indian strains of the bacterial symbionts could have evolved from some other ancestor.

    ABSTRACT An adequate food intake, in terms of quantity and quality, is a key to healthy life. Malnutrition is the most serious consequence of food insecurity and has a multitude of health and economic implications. India has the world's largest population living in slums, and these have largely been underserved areas. The State of Food Insecurity in the World (2012) estimates that India is home to more than 217 million undernourished people. Various studies have been conducted to assess food insecurity at the global level; however, the literature is limited as far as India is concerned. The present study was conducted with the objective of documenting the prevalence of food insecurity at the household level and the factors determining its existence in an urban slum population of northern India. This cross-sectional study was conducted in an urban resettlement colony of South Delhi, India. A pre-designed, pre-tested, semi-structured questionnaire was used for collecting socioeconomic details and information regarding dietary practices. Food insecurity was assessed using Household Food Insecurity Access Scale (HFIAS). Logistic regression analysis was performed to determine the factors associated with food insecurity. A total of 250 women were interviewed through house-to-house survey. Majority of the households were having a nuclear family (61.6%), with mean family-size being 5.5 (SD±2.5) and the mean monthly household income being INR 9,784 (SD±631). Nearly half (53.3%) of the mean monthly household income was spent on food. The study found that a total of 77.2% households were food-insecure, with 49.2% households being mildly food-insecure, 18.8% of the households being moderately food-insecure, and 9.2% of the households being severely food-insecure. Higher education of the women handling food (OR 0.37, 95% CI 0.15-0.92; p≤0.03) and number of earning members in the household (OR 0.68, 95% CI 0.48-0.98; p≤0.04) were associated with lesser chance/odds of being

    Children with autism (CWA) is a segment of population in North East India who are marginalized due to lack of resources like skilled manpower and perceived stress. In comparison to other states and countries whether these children are unique in terms of care and rehabilitation from adult caregivers was the focus of our study. The study assessed level of parental stress, social support, coping mechanisms used by family and resilience in meeting the challenges as caregivers. Parents were selected by simple random sampling from a multi-specialty center dedicated to CWA. They were assessed with the help of structured tools like the Parental Stress Scale, the social support appraisals scale, the coping self-efficacy scale, and the Family Resilience Assessment Scale. Results were analyzed with descriptive statistics and findings suggest definite stress among the parents of CWA. Personal time constraint was noticed in majority of parents, which had adversely affected their professional lives. Despite wide array of stress factors, family members had satisfactory coping skills to work in harmony in adverse circumstances. Regarding secondary social support in terms of family, friends, and neighbors, responses were mixed; religious and spirituality were often resorted avenues. Social desirability, fatigue and the sample being restricted to only one center were though the limitations but, this study throws light on pertinent issues related to families with CWA from a region where specialty centers are a rarity. The future implication could focus on CWA's future, rehabilitation, care and parental concerns which are grossly neglected in North East India. Copyright © 2017 Elsevier B.V. All rights reserved.

    Background: Oral and dental injuries contribute to a major part of sports related injuries in children. Trauma occurring in developing years disrupts normal social functioning and brings about a major impact on quality of life due to their cumulative effect. Objectives: To assess the prevalence and causes of various sports related traumatic orodental injuries among 8 to 16 year school students along with identifying the associated risk factors in North India. Patients and Methods: A cross sectional study consisting of high school students of different organized sports teams aged 8-16 years was carried out in geographical area of north India. The students were selected by multistage cluster sampling methodology. 1105 students from 19 school teams (sports teams) and sports academies participated in study through structured interview and clinical examination in different sports situations. Results: 30.3% (n = 335) of students suffered from orodental injuries. A higher number of girls had injury (32%) than boys (29%), though the difference was not significant. Most of the students suffered from soft tissue injuries (48%) followed by tooth fractures (43%). Maximum numbers of injuries were reported in high velocity (44.1%) and medium intensity sports (46.6%) (P < 0.001) Maximum injuries occurred in basketball (50%) and lowest in the field of badminton (6.1%) (P < 0.05). Amateurs (52%) suffered the most from injuries as per level of coaching. Only 6% of boys and 2% of girls used mouthguards. Conclusions: The result of the present study confirmed that students participating in different organized sports at high school level are at a very high risk of getting orodental injury.

    The guidelines for management of dyslipidemia released by the US National Cholesterol Education Program (NCEP) have been questioned for their relevance in the South Asian Indian populations because these populations are reported to have significantly different lipoprotein parameters and atherogenic risk factors than Western populations. The aim of this study was to determine current prescribing patterns for lipid-lowering drugs (LLDs) adopted by physicians in North India. This prospective, noninterventional, uncontrolled, open-chart, pharmacoepidemiologic study was conducted from June 2000 to August 2000 at a tertiary care hospital in North India and included 200 dyslipidemic patients. The pattern of prescribing LLDs was recorded, along with the serum levels of lipid parameters-total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and lipoprotein(a) (Lp[a])-at the time of initiating LLD therapy and compared with the 1993 NCEP-II therapeutic guidelines for dyslipidemia management. The mean (SD) levels of lipid parameters in the study population were as follows: TC, 223.2 (21.5) mg/dL; TG, 258.4 (61.3) mg/dL; LDL-C, 131.6 (26.5) mg/dL; HDL-C, 39.8 (8.9) mg/dL; and Lp(a), 44.8 (26.8) mg/dL. The LLDs prescribed were fibrates (53.5%) and statins (46.5%). Forty percent of patients prescribed LLDs did not meet the NCEP-II criteria for initiation of LLD therapy. Considerable differences in prescribing patterns of LLDs were observed compared with the then-prevalent NCEP-II guidelines. However, due to the abnormally high serum Lp(a) levels present in the average dyslipidemia profile in South Asian Indian populations, this pattern was in accordance with the specific recommendations made for these populations, as well as with the 2001 NCEP-III guidelines.

    Oral and dental injuries contribute to a major part of sports related injuries in children. Trauma occurring in developing years disrupts normal social functioning and brings about a major impact on quality of life due to their cumulative effect. To assess the prevalence and causes of various sports related traumatic orodental injuries among 8 to 16 year school students along with identifying the associated risk factors in North India. A cross sectional study consisting of high school students of different organized sports teams aged 8-16 years was carried out in geographical area of north India. The students were selected by multistage cluster sampling methodology. 1105 students from 19 school teams (sports teams) and sports academies participated in study through structured interview and clinical examination in different sports situations. 30.3% (n = 335) of students suffered from orodental injuries. A higher number of girls had injury (32%) than boys (29%), though the difference was not significant. Most of the students suffered from soft tissue injuries (48%) followed by tooth fractures (43%). Maximum numbers of injuries were reported in high velocity (44.1%) and medium intensity sports (46.6%) (P < 0.001) Maximum injuries occurred in basketball (50%) and lowest in the field of badminton (6.1%) (P < 0.05).

    Muscodor albus MOW12, an endophytic fungus isolated from Piper nigrum in Mawlong, Meghalaya, India, resembles some cultural and hyphal characteristics of previous isolates of Muscodor sp. In addition, it possesses about 99 % similarity in its ITS rDNA with other M. albus isolates and thus is nicely centered within the genetic tree to other Muscodor spp. This xylariaceae fungus effectively inhibits and kills certain plant pathogenic fungi by virtue of a mixture of volatile compounds that it produces. The majority of these compounds were identified by gas chromatography/mass spectrometry as small molecular weight esters, alcohols, and acids. The main ester components of this isolate of M. albus in its volatile mixture are acetic acid, ethyl ester; propanoic acid, 2-methyl-, methyl ester and acetic acid, 2-methylpropyl ester. This appears to be the first report of any M. albus strain from India.

    Agro-climatic conditions of North-East India are very complex and rice cultivars present in the region have been adapted to grow under harsh environmental conditions. Germplasm present in the region is considered to possess several important and unique traits that are of importance in rice improvement programs. Genetic engineering is a powerful tool to introduce new traits into crop plants. However, not much information is available on the methods to introduce foreign genes into North-East rice cultivars. Therefore, the main objective of this study is to develop transformation procedures for fast recovery of transgenic plants from North-East rice cultivars. To achieve this objective, a systematic study was carried out to identify media components and culture conditions for efficient embryogenic callus induction from the mature seeds and differentiation of callus into plantlets from two North-East deep water rice cultivars, Taothabi and Khongan. Also, role of preculture of callus on Agrobacterium-mediated transformation was studied. Co-cultivation of Agrobacterium with 1-5 days precultured callus was found to result in high frequency of transformation. Detailed characterization of transgenic lines confirmed stable integration of transgenes and expression of reporter gfp gene. The whole process starting from callus induction to regenerating of transgenic rice plants that can be established in the soil was achieved in about 35-45 days. The procedures developed were found to be applicable to a popular variety IR 64. Therefore, methods developed in this study should be useful not only to introduce new traits quickly but also to validate the function(s) of several candidate gene(s) identified under the functional genomics of rice.

    Forests in the mountains are a treasure trove; harbour a large biodiversity; and provide fodder, firewood, timber and non-timber forest products; all of these are essential for human survival in the highest mountains on earth. The present paper attempts a spatiotemporal assessment of forest fragmentation and changes in land use land cover (LULC) pattern using multitemporal satellite data over a time span of around a decade (2000-2009), within the third highest protected area (PA) in the world. The fragmentation analysis using Landscape Fragmentation Tool (LFT) depicts a decrease in large core, edge and patches areas by 5.93, 3.64 and 0.66 %, respectively, while an increase in non-forest and perforated areas by 6.59 and 4.01 %, respectively. The land cover dynamics shows a decrease in open forest, alpine scrub, alpine meadows, snow and hill shadow areas by 2.81, 0.39, 8.18, 3.46 and 0.60 %, respectively, and there is an increase in dense forest and glacier area by 4.79 and 10.65 %, respectively. The change analysis shows a major transformation in areas from open forest to dense forest and from alpine meadows to alpine scrub. In order to quantify changes induced by forest fragmentation and to characterize composition and configuration of LULC mosaics, fragmentation indices were computed using Fragstats at class level, showing the signs of accelerated fragmentation. The outcome of the analysis revealed the effectiveness of geospatial tools coupled with landscape ecology in characterization and quantification of forest fragmentation and land cover changes. The present study provides a baseline database for sustainable conservation planning that will benefit the subsistence livelihoods in the region. Recommendations made based on the present analysis will help to recover forest and halt the pessimistic effects of fragmentation and land cover changes on biodiversity and ecosystem services in the region.

    People who inject drugs (PWID) in India are at high risk for HIV, with women being at elevated risk. Using a socio-ecological framework, this study assessed whether factors associated with HIV transmission risk behaviors differed across men and women PWID. Data for this cross-sectional study were collected from 6449 PWID in 7 cities in Northeast India. Men (n = 5653) and women (n = 796) PWID were recruited using respondent-driven sampling (RDS). We assessed sex differences in two recent HIV transmission risk behaviors: multiple sex partners and needle/syringe sharing. We used multi-level logistic regression models, which incorporated sampling weights and random intercepts for city, to assess factors associated with these HIV risks, separately among men and women. The prevalence of HIV was significantly higher among women than men (53% vs 18.4%, p<0.01). Nearly 13% of men and 8% of women (p = .30) had multiple partners. Employment in men and relationship status and stigma in women were significantly associated with multiple partners. Approximately 25% of men and 19% of women engaged in needle sharing (p = .16). Younger age in women and depression symptoms in men were significantly associated with increased risk for sharing needles. We found that sexual and drug related risk behaviors were common among PWID in Northeast India, and there were differences between men and women in the socio-ecologic correlates of these behaviors. Contextually-integrated and gender-specific HIV prevention and intervention efforts are needed that consider factors at individual, interpersonal- and community-levels that uniquely impact HIV risks among PWID.

    GPS data reveal that the Brahmaputra Valley has broken from the Indian Plate and rotates clockwise relative to India about a point a few hundred kilometers west of the Shillong Plateau. The GPS velocity vectors define two distinct blocks separated by the Kopili fault upon which 2-3 mm/yr of dextral slip is observed: the Shillong block between longitudes 89 and 93°E rotating clockwise at 1.15°/Myr and the Assam block from 93.5°E to 97°E rotating at ≈1.13°/Myr. These two blocks are more than 120 km wide in a north-south sense, but they extend locally a similar distance beneath the Himalaya and Tibet. A result of these rotations is that convergence across the Himalaya east of Sikkim decreases in velocity eastward from 18 to ≈12 mm/yr and convergence between the Shillong Plateau and Bangladesh across the Dauki fault increases from 3 mm/yr in the west to >8 mm/yr in the east. This fast convergence rate is inconsistent with inferred geological uplift rates on the plateau (if a 45°N dip is assumed for the Dauki fault) unless clockwise rotation of the Shillong block has increased substantially in the past 4-8 Myr. Such acceleration is consistent with the reported recent slowing in the convergence rate across the Bhutan Himalaya. The current slip potential near Bhutan, based on present-day convergence rates and assuming no great earthquake since 1713 A.D., is now ~5.4 m, similar to the slip reported from alluvial terraces that offsets across the Main Himalayan Thrust and sufficient to sustain a Mw ≥ 8.0 earthquake in this area.

    Northern regions of India experience severe fog conditions during the winter period (December-January) each year. In the present study, concurrent measurements of black carbon aerosols (BC), Carbon monoxide (CO), Surface Ozone (O 3) and oxides of Nitrgen (NO x) have been carried out in Allahabad, located in northern India in order to understand the impact on pollutant concentrations during fog periods. The results of the present study show higher concentrations of BC, NO x and CO during morning and late night hours in the study area. Diurnal variations of ozone concentrations varied from 14 ppbv to 35 ppbv and were observed to increase gradually after sunrise attaining a maximum value by evening time and to decrease gradually thereafter. Concentrations of BC, NO x, O 3 and CO were found to be very low during fog periods over the study area. BC showed a positive correlation with CO and a negative correlation with surface ozone concentrations. The slope between black carbon aerosols and ground level ozone suggests that every 1 μg m - 3 increase in black carbon aerosol mass concentration causes a reduction of 0.7 μg m - 3 surface ozone.

    The present study was undertaken for a period of two years from December 2010 to May 2012.Studying the benthos of Gulf of Kutch near shore waters is also useful in understanding changes in biological diversity of Gujarat coast. The use of benthos in aquatic ecological research is especially effective in assessing long term changes and detecting input from diffuse sources. The benthos reflects the effects organic enrichment by responding through detectable changes in population dynamics on a time scale of months to years. This is in contrast to plankton which shows a more immediate change to point sources with no long term consequences to the populations (Gray et al 1992). Benthoses were collected from 6 stations on regular basis and were identified. Altogether 60 species belonging to 39 families were identified and placed taxonomically during the course of investigation with sediment samples. Benthic environmental relationship species were observed and recorded. Our studies of monthly comparisons have become an interesting and popular approach in ecology and environmental relationships in the past a number of studies have been conducted on the ecology of macro benthic populations of Gulf of Kutch near shore. My research helps in Gulf of Kutch of the west coast of India has become an important economic asset of the country serving commercial navigation and the fishing sector with environmental relation of benthos in the Gulf of Kutch Gujarat.

    A new species of lygosomatine scincid lizard is described from the sacred forests of Mawphlang, in Meghalaya, northeastern India. Sphenomorphus apalpebratus sp. nov. possesses a spectacle or brille, an unusual feature within the Scincidae, and a first for the paraphyletic genus Sphenomorphus. The new species is compared with other members of the genus to which it is here assigned, as well as to members of the lygosomatine genera Lipinia and Scincella from mainland India, the Andaman and Nicobar Islands, and southeast Asia, to which it also bears resemblance. The new taxon is diagnosable in exhibiting the following combination of characters: small body size (SVL to 42.0 mm); moveable eyelids absent; auricular opening scaleless, situated in a shallow depression; dorsal scales show a line of demarcation along posterior edge of ventral pes; midbody scale rows 27-28; longitudinal scale rows between parietals and base of tail 62-64; lamellae under toe IV 8-9; supraoculars five; supralabials 5-6; infralabials 4-5; subcaudals 92; and dorsum golden brown, except at dorsal margin of lateral line, which is lighter, with four faintly spotted lines, two along each side of vertebral row of scales, that extend to tail base. The new species differs from its congeners in the lack of moveable eyelids, a character shared with several distantly related scincid genera.

    Intestinal infection causing diarrheal disease is a dominant contributor to high morbidity and mortality in developing countries. This intervention study aimed to assess the response of specific anti-microbial and anti-retroviral therapy (ART) on enteropathogens identified in HIV/AIDS adult subjects from northern India. Seventy five ART naive (group 1) and seventy five ART adherent (group 2) HIV/AIDS adult subjects with diarrhea were enrolled. Stool samples from all subjects were examined for enteropathogens by wet mount, staining methods, culture and ELISA. Subjects with enteropathogens were started on specific therapy as per National AIDS Control Organisation, Government of India's guidelines. Follow-up stool samples were examined after 2-4 weeks of completion of therapy for persistence/clearing of enteropathogens. CD4+ T lymphocyte count was done for all subjects. At enrollment, group 1 had 26.13% bacterial, 57.66% parasitic & 16.22% fungal pathogens while group 2 had 11.9%, 69.05% & 19.05% pathogens, respectively. Parasitic diarrhea was more common than bacterial diarrhea. The coccidian parasites (Cryptosporidium spp. & Isospora belli) were the common parasites identified. Clearance of enteric pathogens was significant after specific anti-microbial therapy (p = 0.0001). Persistence of enteropathogens was seen primarily for coccidian parasites. Clearance of enteropathogens after specific therapy and the diagnostic yield of stool specimens were influenced by the CD4+ counts. Immune competence coupled with specific anti-microbial therapy displays the best response against enteric pathogens.

    To describe women who attended two delivery huts in rural Haryana, India. The present observational study assessed routinely collected service provision data from two delivery huts located at primary health centers in the district of Faridabad. Data on sociodemographic characteristics, prenatal care, use of free transport services, and maternal and neonatal indicators at delivery were assessed for all pregnant women who used the delivery hut services from January 2012 to June 2014. During the study period, 1796 deliveries occurred at the delivery huts. The mean age of the mothers was 23.3 ± 3.3 years (95% confidence interval 23.1-23.5). Of 1648 mothers for whom data were available, 1039 (63.0%) had travelled less than 5 km to the delivery hut. The proportion of mothers who belonged to a lower caste increased from 31.0% (193/622) in 2012 to 41.1% (162/394) in 2014. The proportion of mothers who were illiterate also increased, from 8.1% (53/651) in 2012 to 26.4% (104/394) in 2014. Belonging to a disadvantaged social group (in terms of caste or education) was not an obstacle to use of delivery hut services. The delivery huts might have satisfied some unmet needs of community members in rural India. Copyright © 2016 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.

    North-east India, being a corridor to South-east Asia, is believed to play an important role in transmitting drug resistant Plasmodium falciparum malaria to India and South Asia. North-east India was the first place in India to record the emergence of drug resistance to chloroquine as well as sulphadoxine/pyrimethamine. Presently chloroquine resistance is widespread all over the North-east India and resistance to other anti-malarials is increasing. In this study both in vivo therapeutic efficacy and molecular assays were used to screen the spectrum of drug resistance to chloroquine and sulphadoxine/pyrimethamine in the circulating P. falciparum strains. A total of 220 P. falciparum positives subjects were enrolled in the study for therapeutic assessment of chloroquine and sulphadoxine/pyrimethamine and assessment of point mutations conferring resistances to these drugs were carried out by genotyping the isolates following standard methods. Overall clinical failures in sulphadoxine/pyrimethamine and chloroquine were found 12.6 and 69.5% respectively, while overall treatment failures recorded were 13.7 and 81.5% in the two arms. Nearly all (99.0%) the isolates had mutant pfcrt genotype (76T), while 68% had mutant pfmdr-1 genotype (86Y). Mutation in dhps 437 codon was the most prevalent one while dhfr codon 108 showed 100% mutation. A total of 23 unique haplotypes at the dhps locus and 7 at dhfr locus were found while dhps-dhfr combined loci revealed 49 unique haplotypes. Prevalence of double, triple and quadruple mutations were common while 1 haplotype was found with all five mutated codons (F/AGEGS/T) at dhps locus. Detection of quadruple mutants (51I/59R/108N/164L) in the present study, earlier recorded from Car Nicobar Island, India only, indicates the presence of high levels of resistance to sulphadoxine/pyrimethamine in north-east India.

The final goal of the intervention is to reduce maternal and child health inequalities across geographical areas, socioeconomic status groups, and sex of the child. Extensive, in-depth research is necessary to assess the effectiveness of NRHM, on multiple outcome dimensions. This paper presents the design of a new study, able to overcome the shortcomings of previous research. To propose a comprehensive, methodologically sound protocol to assess the extent of implementation and the effectiveness of NRHM measures to improve maternal and child health outcomes and reduce maternal and child health inequalities. A mixed-methods approach (quantitative and qualitative) is proposed for this study in Haryana, a state in North India. NRHM's health sector plans included health system strengthening, specific maternal and child healthcare strategies, and communitization. Mission documents and reports on progress, financial monitoring, and common and joint review will be reviewed in-depth to assess the extent of the implementation of plans. Data on maternal and child health indicators will be obtained from demographic health surveys held before, during, and after the implementation of the first phase of the NRHM (2005-2012) and compared over time. Differences in maternal and child health indicators will be used to measure maternal and child health inequalities; these will be compared pre- and post-NRHM. Focus group discussions (FGDs) with service providers and in-depth interviews with program managers, community representatives, and mothers will be conducted until data saturation is achieved, in two districts of Haryana. Using Nvivo software, an inductive qualitative content analysis will be performed to search for the broader themes across the

    Background A multiple-strategy community intervention, known as National Rural Health Mission (NRHM), launched in India to improve the availability of and access to better-quality healthcare, especially for rural, poor mothers and children. The final goal of the intervention is to reduce maternal and child health inequalities across geographical areas, socioeconomic status groups, and sex of the child. Extensive, in-depth research is necessary to assess the effectiveness of NRHM, on multiple outcome dimensions.

    Background: Migration has been linked to the spread of HIV epidemic from the urban areas of western India to the rural areas of north India. Objectives: This is the first population-based study among the wives of migrant workers of Muzaffarpur district in Bihar with objectives to describe their sexual behavior within marriage, estimate the prevalence of HIV, and to know their awareness regarding HIV/AIDS. Methods: A two-stage cluster survey was conducted by randomly selecting 25 eligible wives from each of the 34 selected villages. A total of 850 wives were interviewed and the blood samples were collected for HIV testing. To determine the factors associated with HIV/AIDS-awareness, we calculated adjusted odds ratios and 95% confidence intervals (CI) using multiple logistic regression analysis. Results: 34 (3%) of 850 wives reported condom use with their husband. HIV prevalence was 0.59% (95% CI: 0.19-1.37%) among the wives of migrant workers. Out of 850 wives, 132 (15.5%) had heard about HIV. Condoms use (OR = 3.21, 95% CI: 1.22-7.90) and premarital sex (OR=7.44, 95% CI: 1.6-33.67) were found significantly positively associated with HIV knowledge of wives. HIV awareness of the wives was significantly associated with age-group 15-24 years, literacy status, and possession of television and husbands’ literacy status. The knowledge about HIV among wives had significant positive impact on condoms use and premarital sex. HIV prevalence among the wives of migrant workers was higher than the prevalence among women in the general population. Education was found to be positively associated with awareness about HIV. Conclusions: Effective interventions are needed for increasing awareness of HIV among wives of migrant workers in Bihar. PMID:28331250

    Giardia duodenalis, Cryptosporidium spp., and Entamoeba spp. are intestinal protozoa capable of infecting a range of host species, and are important causes of human morbidity and mortality. Understanding their epidemiology is important, both for public health and for the health of the animals they infect. This study investigated the occurrence of these protozoans in rhesus macaques (Macaca mulatta) in India, with the aim of providing preliminary information on the potential for transmission of these pathogens between macaques and humans. Faecal samples (n = 170) were collected from rhesus macaques from four districts of North-West India. Samples were analysed for Giardia/Cryptosporidium using a commercially available direct immunofluorescent antibody test after purification via immunomagnetic separation. Positive samples were characterised by sequencing of PCR products. Occurrence of Entamoeba was investigated first by using a genus-specific PCR, and positive samples further investigated via species-specific PCRs for Entamoeba coli, Entamoeba histolytica, Entamoeba dispar and Entamoeba moshkovskii. Giardia cysts were found in 31% of macaque samples, with all isolates belonging to Assemblage B. Cryptosporidium oocysts were found in 1 sample, however this sample did not result in amplification by PCR. Entamoeba spp. were found in 79% of samples, 49% of which were positive for E. coli. Multiplex PCR for E. histolytica, E. dispar and E. moshkovskii, did not result in amplification in any of the samples. Thus in 51% of the samples positive at the genus specific PCR, the Entamoeba species was not identified. This study provides baseline information on the potential for transmission of these zoonotic parasites at the wildlife-human interface.

    To assess the effectiveness of a multi-component school based intervention in improving knowledge and behavioral practices regarding diet, physical activity and tobacco use in middle schoolchildren of rural-Ballabgarh, North-India. A total of 40 middle schools were grouped into two, based on geographic proximity and randomly assigned to the intervention or control group in a cluster randomized controlled trial. The target population consisted of 2,348 children studying in 6th and 7th grades in these schools. The intervention consisted of a school component (policies), a classroom component (activities) and a family component [Information Education & Communication (IEC) material]. The main outcome measures were knowledge and behavioral changes in physical activity, diet and tobacco which were self- reported. Post-intervention, a significant number of intervention schools adopted the tobacco policy (16/19), physical activity policy (6/19) and healthy food policy (14/19) as compared to the control schools (n = 21). Knowledge about physical activity, diet and tobacco improved significantly in the intervention group as compared to the control group. Proportion of students attending Physical Training (PT) classes for five or more days in a week in the intervention group compared to the control group increased significantly (17.8%; p < 0.01). Proportion of students consuming fruits increased in the intervention group compared to the control group (10%; p < 0.01). Pre-post decrease in the prevalence of current smoking was significantly more in the intervention group as compared to the control group (7.7%; p < 0.01). Healthy settings approach for schools is feasible and effective in improving knowledge and behavioral practices of non-communicable diseases (NCD) risk factors in adolescents in rural India.

    Background Like many other low- and middle-income countries, India faces challenges of recruiting and retaining health workers in rural areas. Efforts have been made to address this through contractual appointment of health workers in rural areas. While this has helped to temporarily bridge the gaps in human resources, the overall impact on the experience of rural services across cadres has yet to be understood. This study sought to identify motivations for, and the challenges of, rural recruitment and retention of nurses, doctors and specialists across types of contract in rural and remote areas in India's largely rural north-eastern states of Meghalaya and Nagaland. Methods A qualitative study was undertaken, in which 71 semi-structured interviews were carried out with doctors (n = 32), nurses (n = 28) and specialists (n = 11). In addition, unstructured key informant interviews (n = 11) were undertaken, along with observations at health facilities and review of state policies. Data were analysed using Ritchie and Spencer's framework method and the World Health Organization's 2010 framework of factors affecting decisions to relocate to, stay in or leave rural areas. Results It was found that rural background and community attachment were strongly associated with health workers' decision to join rural service, regardless of cadre or contract. However, this aspiration was challenged by health-systems factors of poor working and living conditions; low salary and incentives; and lack of professional growth and recognition. Contractual health workers faced unique challenges (lack of pay parity, job insecurity), as did those with permanent positions (irrational postings and political interference). Conclusion This study establishes that the crisis in recruiting and retaining health workers in rural areas will persist until and unless health systems address the core basic requirements of health workers in rural areas, which are related to health-sector policies

    Aerial Bay is one of the harbor towns of Andaman and Nicobar Islands, the union territory of India. Nevertheless, it is least studied marine environment, particularly for physico-chemical assessment. Therefore, to evaluate the annual spatiotemporal variations of physico-chemical parameters, seawater samples collected from 20 sampling stations covering three seasons were analyzed. Multivariate statistics is applied to the investigated data in an attempt to understand the causes of variation in physico-chemical parameters. Cluster analysis distinguished mangrove and open sea stations from other areas by considering distinctive physico-chemical characteristics. Factor analysis revealed 79.5% of total variance in physico-chemical parameters. Strong loading included transparency, TSS, DO, BOD, salinity, nitrate, nitrite, inorganic phosphate, total phosphorus and silicate. In addition, box-whisker plots and Geographical Information System based land use data further facilitated and supported multivariate results. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The prevalence of overweight/obesity is increasing worldwide. Although countries like India are typically thought of as having a high prevalence of undernutrition, significant proportions of overweight/obese now co-exist with the undernourished. This study aims to find the prevalence of overweight/obesity, and its association with socioeconomic change, among Tangkhul women in India. The cross-sectional study was carried out among 346 Tangkhul women aged 20-70 years, who were divided into five 10-year age groups. Mean BMI was found to be lowest among the youngest age group, and it increased with age until the age of 59 and then declined. The prevalence of overweight and obesity was found to be 27.1%, as assessed from the Asian cut-off point. Although the prevalence of obesity (2.0%) was low when compared with Indian non-tribal female populations, the prevalence of overweight (25.1%) was not far behind. Overweight and obesity were found to be associated with age, marital status, physical activity level, lifestyle and improvement in socioeconomic status, especially occupation and income. When compared with urban non-tribal Indian females, who have a higher socioeconomic status, the prevalence of overweight/obesity among Tangkhul females is lower, indicating its association with socioeconomic status. Tangkhul Naga is a population where the majority are believed to be thin traditionally owing to the difficult hilly terrain and their physically active lifestyle. With urbanization and economic development, nutritional transition, improved socioeconomic status and an increasingly sedentary lifestyle have been observed, which have contributed to the increasing prevalence of overweight/obesity among Tangkhul Naga women.

    North Eastern Region (NER) of India comprising of eight states considered to be most unique and one of the most challenging regions to govern due to its unique physiographic condition, rich biodiversity, disaster prone and diverse socio-economic characteristics. Operational Remote Sensing services increased manifolds in the region with the establishment of North Eastern Space Applications Centre (NESAC) in the year 2000. Since inception, NESAC has been providing remote sensing services in generating inventory, planning and developmental activities, and management of natural resources, disasters and dissemination of information and services through geo-web services for NER. The operational remote sensing services provided by NESAC can be broadly divided into three categories viz. natural resource planning and developmental services, disaster risk reduction and early warning services and information dissemination through geo-portal services. As a apart of natural resources planning and developmental services NESAC supports the state forest departments in preparing the forest working plans by providing geospatial inputs covering entire NER, identifying the suitable culturable wastelands for cultivation of silkworm food plants, mapping of natural resources such as land use/land cover, wastelands, land degradation etc. on temporal basis. In the area of disaster risk reduction, NESAC has initiated operational services for early warning and post disaster assessment inputs for flood early warning system (FLEWS) using satellite remote sensing, numerical weather prediction, hydrological modeling etc.; forest fire alert system with actionable attribute information; Japanese Encephalitis Early Warning System (JEWS) based on mosquito vector abundance, pig population and historical disease intensity and agriculture drought monitoring for the region. The large volumes of geo-spatial databases generated as part of operational services are made available to the administrators and

    The North-Eastern region (NER) of India, comprising of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland and Tripura, is a hot spot for genetic diversity and the most probable origin of rice. North-east rice collections are known to possess various agronomically important traits like biotic and abiotic stress tolerance, unique grain and cooking quality. The genetic diversity and associated population structure of 6,984 rice accessions, originating from NER, were assessed using 36 genome wide unlinked single nucleotide polymorphism (SNP) markers distributed across the 12 rice chromosomes. All of the 36 SNP loci were polymorphic and bi-allelic, contained five types of base substitutions and together produced nine types of alleles. The polymorphic information content (PIC) ranged from 0.004 for Tripura to 0.375 for Manipur and major allele frequency ranged from 0.50 for Assam to 0.99 for Tripura. Heterozygosity ranged from 0.002 in Nagaland to 0.42 in Mizoram and gene diversity ranged from 0.006 in Arunachal Pradesh to 0.50 in Manipur. The genetic relatedness among the rice accessions was evaluated using an unrooted phylogenetic tree analysis, which grouped all accessions into three major clusters. For determining population structure, populations K = 1 to K = 20 were tested and population K = 3 was present in all the states, with the exception of Meghalaya and Manipur where, K = 5 and K = 4 populations were present, respectively. Principal Coordinate Analysis (PCoA) showed that accessions were distributed according to their population structure. AMOVA analysis showed that, maximum diversity was partitioned at the individual accession level (73% for Nagaland, 58% for Arunachal Pradesh and 57% for Tripura). Using POWERCORE software, a core set of 701 accessions was obtained, which accounted for approximately 10% of the total NE India collections, representing 99.9% of the allelic diversity. The rice core set developed will be a

    The North Almora Thrust zone (NATZ) marks the boundary of the Almora Crystalline Complex (ACC) against the Lesser Himalayan Sedimentary sequence (LHS) in the north. Its southern counterpart, the South Almora Thrust (SAT), is a sharply marked contact between the ACC and the LHS in the south. Published studies argue various contradictory emplacement modes of the North Almora Thrust. Recent studies have implied splays of smaller back thrusts in the NATZ. The present study investigates meso- and microstructures, and strain distribution in the NATZ and compares it with strain distribution across the SAT. In the NATZ, field evidence reveals repeated sequence of 10-500 m thick slices of proto- to ultra-mylonite, thrust over the Lesser Himalayan Rautgara quartzite. In accordance with the field evidence, the strain analysis reveals effects of splays of smaller thrust in the NATZ. The study therefore, argues that contrary to popular nomenclature the northern contact of the ACC with the LHS is not a single thrust plane, but a thrust zone marked by numerous thrust splays.

    The spectro-temporal variation of aerosol optical depth (AOD) and associated physico-optical properties are studied for the period October 2001-November 2010 over a continental location, Dibrugarh (27.3°N, 94.6°E, 111 m amsl) located in the upper Brahmaputra basin of north-east India. The emphasis is on the climatological diurnal asymmetry of AOD and its association with meteorological parameters. AOD is found to be higher during forenoon (FN) hours compared to those in the afternoon (AN) hours in almost all seasons. The mean difference between FN and AN AOD averaged for the period 2001-2010 is 0.18. This variability is found primarily to be driven by the prevailing meteorological conditions including columnar water vapour content. It may also be attributed to the change in the ray path in the forenoon through the polluted industrialised areas located in the east and north-east of Dibrugarh to the cleaner mountain region and river Brahmaputra in the afternoon hours. The estimated CSDs are mostly bimodal in the FN hours while in the AN power law and unimodal character prevails. This indicates dominance of coarse mode aerosols in the forenoon as compared to that in the afternoon. The differences in aerosol modes between FN and AN hours result in the diurnal asymmetry of the modified Ångström coefficients. AOD retrieved from MODIS satellites is also higher in the FN by 0.08 as compared to that in the AN The climatological mean difference between MODIS Terra and Aqua AOD is however, less than the mean difference observed between AOD measured from ground.

    The purpose of this study was to compare the efficacy of tinidazole- versus clarithromycin-based triple regimens for eradication of Helicobacter pylori in North Indian patients of peptic ulcer disease, and to correlate the outcome with in vitro antibiotic susceptibility. One hundred and forty-six H. pylori-infected patients with active ulcer were included in the prospective, randomized study. A total of 70 patients received lansoprazole 30 mg b.d., amoxycillin 1000 mg b.d. and tinidazole 500 mg b.d. (LAT), and 76 patients received lansoprazole 30 mg b.d., amoxycillin 1000 mg b.d. and clarithromycin 500 mg b.d. (LAC) for 14 days. The H. pylori status was assessed by urea breath test, rapid urease test, and histology and antibiotic sensitivity pattern by Epsilometer test. In per-protocol analysis of 112 patients the H. pylori eradication rate was 42.3% (95% confidence interval (CI): 0.29-0.56) in LAT, and 64.8% (95%CI: 0.52-0.78) in LAC (95%CI of difference of proportions: 0.13-0.33, P = 0.01). Ulcer healed in 69.2% in the LAT group (95%CI: 0.57-0.82) and 81.7% in the LAC group (95%CI: 0.72-0.92; P = 0.02). Antibiotic susceptibility testing was done in 31 patients. Metronidazole resistance was present in 41.9% isolates but was unrelated to the outcome of the LAT regimen. Imidazole-based eradication regimens should be abandoned in North India regardless of in vitro susceptibility results.

    A rapid survey was carried out in Shaheed Bhagat Singh Nagar District of Punjab state in India to ascertain health seeking behavior and out-of-pocket health expenditures. Using multistage cluster sampling design, 1,008 households (28 clusters x 36 households in each cluster) were selected proportionately from urban and rural areas. Households were selected through a house-to-house survey during April and May 2014 whose members had (a) experienced illness in the past 30 days, (b) had illness lasting longer than 30 days, (c) were hospitalized in the past 365 days, or (d) had women who were currently pregnant or experienced childbirth in the past two years. In these selected households, trained investigators, using a tablet computer-based structured questionnaire, enquired about the socio-demographics, nature of illness, source of healthcare, and healthcare and household expenditure. The data was transmitted daily to a central server using wireless communication network. Mean healthcare expenditures were computed for various health conditions. Catastrophic healthcare expenditure was defined as more than 10% of the total annual household expenditure on healthcare. Chi square test for trend was used to compare catastrophic expenditures on hospitalization between households classified into expenditure quartiles. The mean monthly household expenditure was 15,029 Indian Rupees (USD 188.2). Nearly 14.2% of the household expenditure was on healthcare. Fever, respiratory tract diseases, gastrointestinal diseases were the common acute illnesses, while heart disease, diabetes mellitus, and respiratory diseases were the more common chronic diseases. Hospitalizations were mainly due to cardiovascular diseases, gastrointestinal problems, and accidents. Only 17%, 18%, 20% and 31% of the healthcare for acute illnesses, chronic illnesses, hospitalizations and childbirth was sought in the government health facilities. Average expenditure in government health facilities was 16.6% less

    Arsenic is a rare crystal element that naturally occurs in all environmental media. A combination of regional and site-specific biogeochemical and hydrological factors governs its dispersion in the environment. It has far reaching consequences on human health. Exposure to arsenic in drinking water has been associated with a decline in intellectual function in children. The aim of this study is to assess the relationship between exposure to arsenic by drinking water and children's intelligence in Karnataka state, India. Twenty school children of age 10-14 years from Sandur, Bellary, Karnataka, and from Hutti, Raichur, Karnataka, were categorized as control and study group, respectively. Water samples were collected from both the villages for the analysis of arsenic and fluoride levels. Hair and nail samples were collected from the participants, and the arsenic levels were determined. Intelligence quotient (IQ) assessment was done using the Raven's Standard Progressive Matrices. Chi-square test, Mann-Whitney U-test, and Fisher's exact test. P < 0.05 was considered statistically significant. There was a significant increase in the arsenic content in the hair and nail samples of children in the study group. The mean IQ tests score in the control group and study group was 30.55 and 17.95, respectively, and this difference was statistically significant. Chronic arsenic exposure could be a possible cause for the reduced IQ scores seen in children residing in Hutti, Raichur District, North Karnataka.

    Melocanna baccifera (Roxb.) Kurz is an economically important bamboo of North-East India experiencing population depletion in its natural habitats. Genetic variation studies were conducted in 7 populations sampled from 5 districts of Manipur using ISSR molecular markers. The investigation was carried out as a primary step towards developing effective conservation strategies for the protection of bamboo germplasm. ISSR marker analysis showed significant level of genetic variation within the populations as revealed by moderately high average values of Nei's genetic diversity (H 0.1639), Shannon's diversity index (I 0.2563), percentage of polymorphic bands (PPB 59.18), total genetic variation (Ht 0.1961), and genetic diversity within population (Hs 0.1639). The study also divulged a high genetic variation at species level with Shannon's diversity index (I), Nei's genetic diversity (H), and percentage of polymorphic band (PPB%) recorded at 0.3218, 0.1939, and 88.37, respectively. Genetic differentiation among the populations (Gst) was merely 19.42% leaving 80.58% of genetic variation exhibited within the populations. The low genetic diversity between populations was consistent with AMOVA. The low genetic differentiation among populations coupled with existence of significantly high genetic diversity at species level indicated the urgent necessity of preserving and protecting all the existing natural bamboo populations in the region.

The study also divulged a high genetic variation at species level with Shannon's diversity index (I), Nei's genetic diversity (H), and percentage of polymorphic band (PPB%) recorded at 0.3218, 0.1939, and 88.37, respectively. Genetic differentiation among the populations (Gst) was merely 19.42% leaving 80.58% of genetic variation exhibited within the populations. The low genetic diversity between populations was consistent with AMOVA. The low genetic differentiation among populations coupled with existence of significantly high genetic diversity at species level indicated the urgent necessity of preserving and protecting all the existing natural bamboo populations in the region.

    Rhipicephalus (Boophilus) microplus is the most common tick species in India infesting cattle and buffaloes and causing significant economic losses to dairy and leather industries by adversely affecting the milk production and quality of hides. A study to evaluate the acaricide resistance status of Rhipicephalus (Boophilus) microplus to deltamethrin, flumethrin, and fipronil was conducted on the samples collected from organized and unorganized farms of North Gujarat state, where treatment failures were reported frequently. Adult Immersion Test (AIT) and Larval Packet Test (LPT) were conducted using field strain for determination of 50 and 95% lethal concentration of deltamethrin, flumethrin, and fipronil. Results obtained by the Adult Immersion Test showed low grade resistance (level I, RF > 5) has been developed against both deltamethrin and fipronil. However, deltamethrin by performing Larval Packet Test showed moderate grade resistance (level II, RF > 25). Larval packet performed by flumethrin also revealed low grade resistance, level I. The data on field status of acaricide resistance from the area with diversified animal genetic resources will be helpful to adopt suitable strategy to overcome the process of development of resistance in ticks.

    Intramuscular injections can provoke muscular paralysis especially, if the child has had exposure to polio virus. The purpose of the study was to determine the association with known risk factors for motor disabilities in two remote villages of North Karnataka (India), where an increased number of disabled people among select communities had been reported. A community based survey was conducted. The selection of study subjects was done through screening, history related with occurrence of musculoskeletal disability, screening and general examination of the affected joints and muscles. Data analysis was done by estimation of percentages. Among the physical disabilities identified, the most common was post-polio residual paralysis. 35.65% (n = 41) subjects had developed paralysis following the administration of an intramuscular injection when they had acute viremia in childhood, indicating that (probably) muscle paralysis would have been provoked by intramuscular injections, resulting in provocative poliomyelitis. Unnecessary injection must be avoided in children during acute viremia state and use of oral polio vaccine should be encouraged.

    A viable option for increasing nitrogen (N) use efficiency and mitigation of negative impacts of N on the environment is to capitalize on multi-element interactions through implementation of nutrient management programs that provide balanced nutrition. Numerous studies have demonstrated the immediate efficacy of this approach in the developing regions like China and India as well as developed countries in North America. Based on 241 site-years of experiments in these countries, the first-year N recovery efficiency (RE) for the conventional or check treatments averaged 21% while the balanced treatments averaged 54% RE, for an average increase of 33% in RE due to balanced nutrition. Effective policies to promote adoption are most likely those that enable site-specific approaches to nutrient management decisions rather than sweeping, nation-wide incentives supporting one nutrient over another. Local farmers, advisers and officials need to be empowered with tools and information to help them define necessary changes in practices to create more balanced nutrient management.

    Uranium (U)-tolerant aerobic chemo-heterotrophic bacteria were isolated from the sub-surface soils of U-rich deposits in Domiasiat, North East India. The bacterial community explored at molecular level by amplified ribosomal DNA restriction analysis (ARDRA) resulted in 51 distinct phylotypes. Bacterial community assemblages at the U mining site with the concentration of U ranging from 20 to 100 ppm, were found to be most diverse. Representative bacteria analysed by 16S rRNA gene sequencing were affiliated to Firmicutes (51%), Gammaproteobacteria (26%), Actinobacteria (11%), Bacteroidetes (10%) and Betaproteobacteria (2%). Representative strains removed more than 90% and 53% of U from 100 μM and 2 mM uranyl nitrate solutions, respectively, at pH 3.5 within 10 min of exposure and the activity was retained until 24 h. Overall, 76% of characterized isolates possessed phosphatase enzyme and 53% had PIB-type ATPase genes. This study generated baseline information on the diverse indigenous U-tolerant bacteria which could serve as an indicator to estimate the environmental impact expected to be caused by mining in the future. Also, these natural isolates efficient in uranium binding and harbouring phosphatase enzyme and metal-transporting genes could possibly play a vital role in the bioremediation of metal-/radionuclide-contaminated environments.

    The study described here is based on the measurements of soil gas radon-thoron concentrations performed at Dharamsala region of north-west (NW) Himalayas, India. The study area is tectonically and environmentally significant and shows the features of ductile shear zone due to the presence of distinct thrust planes. Solid state nuclear track detectors (LR-115 films) have been used for the soil gas radon-thoron monitoring. Twenty five radon-thoron discriminators with LR-115 films were installed in the borehole of about 50 cm in the study areas. The recorded radon concentration varies from 1593 to 13570 Bq/m3 with an average value of 5292 Bq/m3. The recorded thoron concentration varies from 223 to 2920 Bq/m3 with an average value of 901 Bq/m3. The anomalous value of radon-thoron has been observed near to the faults like main boundary thrust (MBT and MBT2) as well as neotectonic lineaments in the region.

    Background. Hypertension is a leading cause of morbidity and mortality worldwide. We aimed to evaluate the prevalence of hypertension in a population of male bus drivers in North Kerala, India. Methods. The study population included male bus drivers of Corporation Bus stand Kozhikode, Kerala. Blood pressure, height, and weight of subjects were measured, and relevance was obtained using a structured questionnaire. Results. Age varied from 21 to 60 years (mean 36.5 ± 8.4). Among 179 bus drivers studied, 16.8% (30/179) had normal BP, 41.9% (75/179) had prehypertension, and 41.3% (74/179) had hypertension. Isolated systolic HTN was seen in 6.70% (12/179) individuals. Out of 74 hypertensives, 9 (12.1%) were aware of their hypertension, while 3 (4.0%) were medicated and only 1 (1.3%) had BP adequately controlled. Age > 35 years (P = 0.015), BMI ≥ 23 kg/m(2) (P = 0.007), supporting more than four family members (P = 0.011), and taking main meals from restaurants on most working days (P = 0.017) were independently associated with HTN in binary logistic regression. Conclusion. Prevalence of hypertension was high among bus drivers. Age > 35 years, elevated BMI, supporting a large family, and dietary habits associated with the job showed significant association with hypertension. Primary and secondary prevention strategies need to be emphasized in this occupational group.

    Genotoxicity is one of the important endpoints for risk assessment of various lifestyle factors. The study is the first report on the genotoxic effect associated with sadagura, a unique smokeless tobacco prepared in southern Assam province of North-East India. Sadagura is consumed with or without betel quid and/or smoking. In the present cytogenetic monitoring study, analysis of micronuceus (MN), nuclear bud, binucleated, karyorrhectic, karyolytic and pyknotic cells tests were performed in the exfoliated buccal cells of 75 habituates and compared to controls matched for gender, age, and habit. Significant increase in the frequency of MN was found in sadagura chewers (0.48%, P < 0.001), smokers (0.46%, P < 0.01), betel quid with sadagura chewers (0.91%, P < 0.001) and smokers chewing betel quid with sadagura (0.53%, P < 0.001) as compared to the unexposed control group (0.07%). Betel quid chewers showed significant increase (1.65%, P < 0.05) in the frequency of binucleated cells as compared to the control group (0.16%). Results of this study demonstrated that sadagura consumed as a single agent or in combination with betel quid, leads to a significant induction of cytogenetic damage in the buccal epithelial cells of habituates. We suggest that analysis of other degenerative nuclear changes in addition to MN can provide valuable information while evaluating potential genotoxic agents.

    A total of 333 blood samples were collected from cattle suspected for haemoprotozoan infections from three states of north-eastern part of India. All the samples were examined for diagnosis of Babesia bigemina infection using PCR for detection of specific DNA. Out of these, 12 (3.60%) samples were found positive for B. bigemina DNA on PCR using the organism-specific primers derived from 18S ribosomal RNA (rRNA) gene of B. bigemina. An expected size of 1124-bp PCR product was visualized on agarose gel electrophoresis with all the 12 samples, and four of the products was further cloned and sequenced. Basic Local Alignment Search Tool (BLAST) analysis of B. bigemina sequences generated in the present study share 99.2 to 99.7% identity at 18S rRNA gene nucleotide sequence level. These Indian B. bigemina sequences were found to be closely related with the cognate gene nucleotide sequences of B. bigemina from Argentina and Kenya where 99.1 to 99.9% and 99.0 to 99.7% nucleotide identities were observed, respectively. Distant relationship of these Indian organisms was observed with few cognate gene sequences from China where more than 7% divergence was observed in the distance matrix.

    Soil (222)Rn concentration, CO2 and CH4 flux measurements were conducted around the Jwalamukhi area of North-West Himalayas, India. During this study, around 37 soil gas points and flux measurements were taken with the aim to assure the suitability of this method in the study of fault zones. For this purpose, RAD 7 (Durridge, USA) was used to monitor radon concentrations, whereas portable diffuse flux meter (West Systems, Italy) was used for the CO2 and CH4 flux measurements. The recorded radon concentration varies from 6.1 to 34.5 kBq m(-3) with an average value of 16.5 kBq m(-3) The anomalous value of radon concentrations was recorded between Jwalamukhi thrust and Barsar thrust. The recorded average of CO2 and CH4 flux were 11.8 and 2.7 g m(-2) day(-1), respectively. The good correlation between anomalous CO2 flux and radon concentrations has been observed along the fault zone in the study area, suggesting that radon migration is dependent on CO2. © The Author 2016.

    The purpose of this study was to determine the prevalence of various Candida species and study some of their virulence factors among thevulvovaginal candidiasis(VVC)patients. The study was conducted in a Tertiary Care University Hospital in North India. This study was carried out prospectively for a period of 1 year. High vaginal swabs (HVSs) were collected from women in childbearing age group attending the gynecology and obstetrics out-patient departments with the complaints suggestive of vulvovaginitis. Samples were plated on Sabouraud's dextrose agar slope. Candida spp. isolated was further speciated based on microscopy, biochemical tests and culture characteristics on special media. Virulence factors of these strains were determined by biofilm formation and phospholipase activity. A total of 464 HVS from 232 patients with the complaints of vulvovaginitis were included in this study. Following laboratory workup, 71 specimens were positive for genus Candida (30.6%). Further speciation showed 32.4% as Candida albicans, 45.07% Candida parapsilosis and 22.53% of Candida glabrata. Biofilm production was shown by 50 candidal strains (70.4%) and phospholipase activity was given by 41 candidal strains (57.74%). Our study suggests increasing prevalence of non-albicans Candida among the VVC cases along with their virulence factors. Therefore, we recommend that microbiological investigation upto species level should be mandatory to determine the emergence of non-albicans Candida as a major cause of VVC.

    Background: Oral cancer is one of the most common life-threatening diseases all over the world. Developing countries face several challenges to identify and remove potential risk factors. Chewing tobacco/pan masala is considered to be the most potent risk factor for oral precancerous lesions and oral cancer. Objectives: To investigate the relative occurrence of different oral pre-cancerous lesions and oral cancer in North India and to identify the associated risk factors. Materials and Methods: A hospital-based study was conducted and 471 subjects were recruited in the study. The subjects comprised patients with squamous cell carcinoma (n = 85), oral submucous fibrosis (n = 240), leukoplakia (n = 32), lichen planus (n = 15), and controls (n = 99). Statistical analysis of the data was done using Chi-square and regression analysis. Results: A strong correlation was observed between the presence of the chewing habit in all the oral precancerous lesions and oral cancer. Duration of the habit and intensity of habit ware also strongly correlated with the risk of oral precancerous lesions and oral cancer. Other factors such as alcohol and smoking were found to be less important in concern with oral cancer and precancerous lesions. PMID:25937723

    To assess the knowledge about hepatitis B among the medical, dental and nursing students of first year in Subharti University, a private medical university of North India. A cross sectional institutional study was conducted among the first year students of medical, dental and nursing colleges of Subharti University. The total subjects studied were 250. Data was collected when the student came up for hepatitis B vaccination in the Department of Community Medicine. Data was entered in MS Excel and analyzed using Epi Info for Windows. Bivariate analysis using Chi-square test was applied. Overall, 83.32% of the study subjects had heard of hepatitis B. Only 42% knew that virus is a cause of hepatitis B. Awareness of mother to child transmission of hepatitis B was present in only 12% of the study subjects. Unsafe blood transfusion as a risk factor of hepatitis B was known by 35.2%, whereas, prevalence of knowledge regarding reused needles and unsafe sex as risk factors was lesser. Forty-four percent of the study subjects were not aware of vaccination against hepatitis B. There was a significant difference in the proportion of students of the different faculties about the correct knowledge about hepatitis B. The knowledge about hepatitis B was very low among the students entering in the medical, dental and nursing profession. This highlights the importance of informed and evidence based education programmes among the students of these healthcare professions.

    The northernmost exposures of sub-Himalayan Cenozoic strata in the Hazara-Kashmir syntaxial region of north Pakistan comprises the Paleocene-Eocene marine strata in the lower part and Oligocene-Miocene nonmarine strata in the upper part. This study provides the detrital zircon U-Pb geochronology of the Cenozoic strata in this area. The strong resemblance of U-Pb age spectra of Paleocene Hangu, Lockhart and Patala formations with those of Himalayan strata indicate an Indian plate provenance. The first appearance of <100 Ma detrital zircon U-Pb ages within the lower most part of the Early Eocene Margalla Hill Limestone indicates a shift from an Indian to Asian provenance. Geologic mapping shows the existence of a disconformity between the lower and upper most part of the Patala Formation, which is interpreted to have been formed by the migration of a flexural forebulge through this region. We consider the upper most part of the Patala Formation to have been deposited within the distal foredeep of the foreland basin. The Indian to Asian provenance shift and the presence of a possible foreland basin forebulge provide strong evidence that India-Asia collision was underway in northern Pakistan at ca. 56-55 Ma.

    A modified DRASTIC model in a geographic information system (GIS) environment coupled with an information-analytic technique called `rough sets' is used to understand the aquifer vulnerability characteristics of a segment of the lower Kali watershed in western Uttar Pradesh, India. Since the region is a flat plain, topography (T) is removed as a potential control. Other parameters are the same as in DRASTIC, hence the new model is termed as DRASIC. The rough set technique is employed to provide insight into the relative vulnerabilities of different administrative units (blocks) within the study area. Using rough sets, three important factors are computed: strength, certainty and coverage. Strength indicates how the vulnerability characteristics vary in the entire area, certainty gives the relative fractions of low, medium and high vulnerability regions within a particular block, and coverage computes the percentage of a particular vulnerability state in each block. The purpose of the work is to demonstrate the utility of this integrated approach in classifying different administrative blocks in the study area according to their aquifer vulnerability characteristics. This approach is particularly useful for block-level planning and decision making for sustainable management of groundwater resources.

    The study of ethnobotany relating to any tribe is in itself a very intricate or convoluted process. This paper documents the traditional knowledge of medicinal plants that are in use by the indigenous Jaintia tribes residing in few isolated pockets of northeast India. The present study was done through structured questionnaires in consultations with the tribal practitioners and has resulted in the documentation of 39 medicinal plant species belonging to 27 families and 35 genera. For curing diverse form of ailments, the use of aboveground plant parts was higher (76.59%) than the underground plant parts (23.41%). Of the aboveground plant parts, leaf was used in the majority of cases (23 species), followed by fruit (4). Different underground plant forms such as root, tuber, rhizome, bulb and pseudo-bulb were also found to be in use by the Jaintia tribe as a medicine. Altogether, 30 types of ailments have been reported to be cured by using these 39 medicinal plant species. The study thus underlines the potentials of the ethnobotanical research and the need for the documentation of traditional ecological knowledge pertaining to the medicinal plant utilization for the greater benefit of mankind.

    In the global climate change scenario, application of biochar in soil has become one of the important management practices for carbon sequestration, soil health improvement and climate change mitigation. In this study, an attempt was made to see the effect of biochar prepared from weed biomass on soil properties in subtropical northeast India. Biochar were prepared from seven locally available weed biomass viz. Ageratum conyzoides, Lantana camera, Gynura sp., Setaria sp., Avena fatua, Maize stalk, Pine needles and were characterised. Apot experiment was conducted with maize, where biochar was applied alone and in combination with fertilizers. Results revealed that biochar had significant impact on soil pH, SOC, and available nutrients like N, P and K. It also had significant impact on maize biomass yield. All biochar contained more than 50% stable carbon. Increase in soil pH was in the range of 0.26 to 0.3 and that of SOC from 1.62% in control to 1.74% in biochar added treatments. Biochars alone improved the available nitrogen ranging from 4.5 to 21.3 mg kg(-1), available P from 3.32 to 3.68 mg kg(-1) and increased K content by 20% above control. Weed biomass can be potential alternative to enhance soil and crop productivity through conversion into biochar.

    Numerous studies show that exposure to entertainment-education-based mass media campaigns is associated with reduction in risk behaviors. Concurrently, there is a growing interest in comparing the cost-effectiveness of HIV prevention interventions taking into account infrastructural and programmatic costs. In such analyses, though few in number, mass media campaigns have fared well. Using data from a mass media communication campaign in the low HIV prevalence states of Uttar Pradesh, Rajasthan, and Delhi in Northern India, in this article we examine the following: (1) factors that mediate behavior change in different components of the campaign, comprising a TV drama, reality show for youth audiences, and TV spots; (2) the relative impact of campaign components on the behavioral outcome: condom use; and (3) the cost-effectiveness calculations arising from this analysis. Results suggest that recall of the TV spots and the TV drama influences behavior change and is strongly associated with interpersonal communication and positive gender attitudes. The TV drama, in spite of being the costliest, emerges as the most cost-effective component when considering the behavioral outcome of interest. The analysis of the comparative cost-effectiveness of individual campaign components provides insights into the planning of resources for communication interventions globally.

    Introduction Oral squamous cell carcinoma (OSCC) ranks 12th most common cancer in the world. Objective The aim of this study was to retrospectively evaluate the OSCC. Methods A retrospective study of 611 OSCC patients from January 2010 to December 2013 was carried out in Department of Surgical Oncology, King George's Medical University, Lucknow, India. Details of patient's sex, age, tobacco habit and site of cancer were noted. Data were analyzed by Student's t test and chi-squire (χ2) test. Results The prevalence of OSCC was significantly (p < 0.001) higher in males (75.9%) than females (24.1%). The mean age of female patients was higher than males (p < 0.001). In both the genders, the buccal mucosa and gingivobuccal sulcus were found to be the most affected sites. Moreover, the smokeless form of tobacco was found to be significantly associated with OSCC, especially in females. Conclusion The study concluded that OSCC is more common in men as compared to women, probably due to habit of tobacco consumption. Smokeless tobacco use is an important risk factor, especially in females. PMID:26937366

    The effect of the glass industry on urban soil metal characterization was assessed in the area of Firozabad, India. A comprehensive profile of metal contamination was obtained in five zones each containing five specific sites. Zn, Cd, and As showed a greater accumulation, whereas accumulation of Ni and Cu was high in limited samples. Positive correlation was found for the metal pairs Cu-Zn, Cu-Co, and Cu-Cr at P < 0.01. Moderate positive correlation was also observed between Zn-Co, Mn-Cd, Mn-As, Pb-As, and Ni-Cu at P < 0.05. Integrated contamination indices indicate that 60% of the sites were heavily contaminated while 28% were moderately contaminated. Phytoremedial potential of native flora (twenty herbs, three shrubs, and two grasses) was also assessed by analyzing their metal uptake. Individual elements displayed remarkably different patterns of accumulation in soils as well as in plants. Mn, Zn, Cu, and As were predominantly partitioned in shoots, Co and Cd in roots while Pb, Cr, and Ni almost equally between shoots and roots. Most plants exhibited capabilities in mobilizing Co, Pb, Cr, and Ni in the root zone. Potential phytoextractors include Datura stramonium and Chenopodium murale while phytostabilizers include Calotropis procera and Gnaphalium luteo-album. Poa annua showed potential in both categories. None of the species showed phytoremedial potential for Co and Ni.

    Background: Delhi, the capital of India, has suffered many outbreaks of dengue in recent past and despite the obvious magnitude of problem, very scarce evidence exists that documents the knowledge, awareness and practices of the people regarding dengue. Aim: To assess the knowledge and practices related to control of dengue fever and to assess the differences in knowledge and practices based on sex and literacy. Materials and Methods: A cross-sectional study was conducted among persons visiting a tertiary care hospital in New Delhi. A systematic sampling procedure was adopted and a pretested questionnaire was used. Results: A total of 215 individuals were interviewed. Majority of the respondents (96.3%) had heard about dengue. The important sources of information were television (54.9%) and newspaper/magazines (51.7%). Around 89% of the study participants considered dengue as “serious problem”. Nearly 86% participants were aware of the spread of dengue by mosquitoes while 73% were aware of one of the correct breeding sites of Aedes mosquito. Mosquito mats/liquidators were used by 61% of respondents, coils by 56% and repellant creams by 22%. Conclusion: The awareness regarding dengue and mosquito control measures was satisfactory to an extent. Programs should focus that this knowledge gets translated into practice. PMID:22754880

    This work focuses on minimising inaccuracies in distributional assumptions of speed data on two-lane roads with heterogeneous traffic to improve accuracy in capacity and level of service analysis. Accordingly, field study was conducted on a two-lane highway in India that exhibits heterogeneity in its traffic composition. Two distribution functions, namely, normal and logistic were examined for the observed speed data. The appropriate function was chosen using a methodology based on K-S test and field validation. Logistic distribution function was found to exhibit its aptness in describing speed under such traffic and was, thereby, considered in estimating the limiting speed of slower vehicles that tends to obstruct the flow of traffic. Vehicles that move at or below this speed cause delay to the faster ones resulting in formation of platoons at moderate and heavy flow when passing is restricted. Since the percent time-spent-following, a performance measure to assess level-of-service of two-lane highways, considers proportion of vehicles that are trapped inside platoons, it is imperative to estimate the limiting speed of slower vehicles correctly to approximate the delayed vehicles.

    Iron deficiency anemia is the most frequent micronutrient deficiency in the developing countries like India especially affecting pregnant women and young children. Iron is an essential element involved in myelin formation, neurotransmitter synthesis and neuro-metabolism. Several behavioural disturbances have been reported in iron deficient children. In the present study, we determined the prevalence of iron deficiency anemia in children with behavioural disorders and assessed the improvement in terms of symptoms (by child behaviour check list), haematological parameters and iron status after treatment with oral iron. In this prospective study, 44 children in the age group of 3-12 years who were diagnosed with behavioural disorders were evaluated. Complete blood counts using automated hematology analyzer and iron parameters (serum iron, total iron binding capacity, % transferrin saturation and serum ferritin) were measured in all the patients to assess the prevalence of iron deficiency in these children. Thirty age matched controls were also studied. Iron deficiency was found in 32 (73%) children, as assessed by transferrin saturation <16% and/or serum ferritin <16 μg/l. Following treatment with iron for 100 ± 10 days, there was a statistically (P ≤ 0.05) significant improvement in the clinical features, haematological profile and iron status. The presence of iron deficiency in children with behavioural disorders and subsequent improvement in clinical features, haematological profile and iron status suggests a possible causal relationship between iron deficiency and behavioural disorders.

    Blood pressure readings were collected from 1042 adult females of rural and urban Jat Sikh community of Punjab, a north Indian State. Anthropometric measurements like height, weight and skinfold thickness were also collected. The difference between rural and urban females in systolic, diastolic and mean arterial blood pressure was found to be statistically significant. All anthropometric variables and age have a significant positive association with blood pressure. The effects of anthropometric variables on blood pressure were assessed simultaneously through stepwise multiple regression analysis. All 'F' ratios have been found highly significant (p < 0.001) among both rural and urban female population.

    Obesity is a very common disorder resulting from an imbalance between food intake and energy expenditure, and it has a substantial impact on the development of chronic diseases. The aim of this study was to examine the association of INSIG2 (rs7566605) gene polymorphism with obesity and obesity associated phenotypes in North Indian subjects. The variants were investigated for association in 642 obese and non-obese individuals. The genotyping of INSIG2 (rs7566605) single nucleotide polymorphism was analyzed by the TaqMan allelic discrimination protocol. A significant association was observed for INSIG2 (rs7566605) single nucleotide polymorphism with obesity and obesity-related phenotypes. Furthermore, a significant relationship was found between the rs7566605 and insulin, homeostasis model of assessment-insulin resistance, the percentage of body fat, fat mass, leptin, and adiponectin. The present study observed significant association between INSIG2 (rs7566605) single nucleotide polymorphism and obesity, as well as obesity-associated phenotypes in North Indian population.

    We examine the conditions and processes of growth and preservation of multiaged monazite in micaceous matrix and in garnet porphyroblasts in staurolite-kyanite mica schists hosted in a hitherto-undiscovered shear zone that limits the northern extent of the Western Dharwar Craton (WDC), India. Garnet in the footwall schists grew during mid-crustal (600 ± 40 °C, 7.3 ± 1.2 kbar) loading and cooling as a consequence of the northward transport of the WDC lithologies. U-Th-Pb (total) ages in monazites in the matrix and in post-tectonic garnets yield well-defined peaks at 2.5, 2.2 and 1.9 Ga. In garnet, 2.5 and 2.2 Ga monazite grains, and 2.2 Ga monazites with 2.5 Ga cores are commonly occluded, but monazites with 1.9 Ga mantles around older cores are rare. By contrast, in the matrix, 1.9 Ga monazite grains and monazite with 1.9 Ga mantles around older cores are prominent, but the peak age frequencies of the two older populations are significantly lower than for monazites hosted as inclusions in garnet. Both in the matrix and garnet, the low-Th, high-Y domains in monazites yield the two older peak ages, while the 1.9 Ga ages correspond to the high-Th, low-Y domains. The preponderance of older ages in monazite hosted as inclusions in garnet relative to matrix monazites is because garnets formed between 2.2 and 1.9 Ga shielded the older monazites from dissolution-precipitation at 1.9 Ga. A few 1.9 Ga monazites hosted as inclusions in the garnet rims suggest renewed garnet growth at post-1.9 Ga. Multiple Pb-Pb age populations (2.5, 2.25, 2.1 and 1.8 Ga) in detrital zircon in the Sahanataha Group north of the Paleoarchean Antongil-Masora block (NE Madagascar) are identical to the multiple monazites ages north of the WDC, inferred to share a similar history and to be contiguous with the Antongil-Masora block in pre-Jurassic reconstructions of the Gondwanaland. We suggest the newly discovered Paleoproterozoic tectonic zone continued westward into Madagascar north of the

    HIV exposed children are vulnerable to developmental delay irrespective of their HIV status due to combined effect of risk factors like poverty, prenatal drug exposure, stress and chronic illness in family and malnutrition. This cohort study assessed the development of 50 HIV exposed children aged 6-18 months at a Pediatric Centre of Excellence in HIV care in India. The development was assessed using Development Assessment Scale for Indian Infants (DASII) at enrolment, 3 and 6 months later. The development quotient (DQ) scores and proportion of children with developmental delay (DQ ≤ 70) were compared among two sub-groups, HIV infected (HI) and HIV exposed uninfected (HEU) children. The various social and clinical factors affecting development were studied by univariate and multivariate analysis. Prevalence of developmental delay was 2.4% in the HEU (n = 41), and 33.3% in HI (n = 9). The DQ of HI was significantly lower than that of HEU at all three assessments. The DQ of HI were also significantly lower compared to the HEU at ages 12.1-18 months (83.37 ± 20.73 vs 94.68 ± 5.13, p = 0.005) and 18.1-24 months (84.55 ± 15.35 vs 94.63 ± 5.86, p = 0.006) respectively. The development of HEU was adversely affected by lower socioeconomic status and presence of wasting. In addition, development of HI was also adversely influenced by presence of stunting and opportunistic infections, advanced disease stage and shorter ART duration. We conclude that with optimum care, HEU can have a normal development, while a considerable proportion of HI may continue to have delayed development.

    Chikungunya fever is an emerging mosquito-borne disease caused by the infection with chikungunya virus (CHIKV). The CHIKV has been rarely detected in mosquito vectors from Northern India, since vector surveillance is an effective strategy in controlling and preventing CHIKV transmission. Thus, virological investigation for CHIKV among mosquitoes of Aedes (A.) species was carried out in the Lucknow district during March 2010 to October 2011. We collected adult mosquitoes from areas with CHIKV positive patients. The adult Aedes mosquito samples were pooled, homogenized, clarified and tested for CHIKV by nonstructural protein 1 (nsP1) gene based polymerase chain reaction (PCR). A total 91 mosquito pools comprising of adult A. aegypti and A. albopictus were tested for CHIKV. The partial envelope protein (E1) gene sequences of mosquito-borne CHIKV strains were analyzed for genotyping. Of 91 pools, 6 pools of A. aegypti; and 2 pools of A. albopictus mosquitoes were identified positive for CHIKV by PCR. The phylogenetic analysis revealed clustering of CHIKV strains in two sub-lineages within the monophyletic East-Central South African (ECSA) genotype. Novel amino acid changes at the positions 294 (P294L) and 295 (S295F) were observed during analysis of amino acid sequence of the partial E1 gene. This study demonstrates the genetic diversity of circulating CHIKV strains and reports the first detection of CHIKV strains in Aedes vector species from the state of Uttar Pradesh. These findings have implication for vector control strategies to mitigate vector population to prevent the likelihood of CHIKV epidemic in the near future.

    The Indo Gangetic Plain (IGP) has been identified from back-trajectory analyses, as one of the most potential region affecting the species transport to the Northeastern region of India (NER). The continental export efficiency (εε) of BC, NOx and SO2 within the boundary layer is estimated in order to examine how efficiently these chemical species are transported towards the NER. For this the measurements carried out at Dibrugarh, a wet tropical location in NER during 2012-2013 have been used as the references in the estimation of the species enhancements above their background. CO is used as a passive tracer of transport due to its longer lifetime in the atmosphere. The emission estimat
