    The Indian subcontinent is seismically one of the most active regions in the world, having experienced four earthquakes of magnitude greater than 8.0 during the last century. This has necessitated detailed Seismic Microzonation approaches for assessment of seismic hazard and risk potential of several highly populated Indian mega-cities that face the wrath of future earthquakes. A multi-disciplinary and multi-Institutional pilot study was launched in the Jabalpur urban area in Central India for a realistic assessment of seismic hazard and the associated risk to the region. Ground amplification at local sites in the frequency range of 0.1 - 10 Hz was obtained at more than 100 sites in and around Jabalpur using the conventional Nakamura technique to estimate the predominant frequencies and the site amplification at those frequencies for each site. A strong correlation is seen between the predominant frequencies and the ground conditions, like the local geology, the composition of the top soil cover, its thickness and impedance contrast with respect to the basement, etc. To validate these results, Multichannel Analysis of Surface Waves (MASW) technique was adopted, coupled with refraction measurements over short profiles (~100m). This has resulted in detailed shear velocity images of the shallow subsurface, which are crucial for estimation of the amplification of seismic signals propagating through the medium. Based on these results synthetic seismograms were generated using a hybrid method comprising normal mode summation for the regional 1D structure and the Finite difference approach for site specific 2D structure of the medium. Local site amplifications expressed as the Response Spectral Ratios (RSR) - the ratio of 2D to 1D ground acceleration response - were estimated. In general, the RSR values correlated well with the composition and thickness of the upper soil cover. The alluvial filled region in the northwestern part of Jabalpur having soil thickness up to 30

    Background To investigate the prevalence of depression, suicidal ideations, alcohol and nicotine consumption in adults in an agrarian society mostly unchanged by the effects of urbanization. Methods The Central India Eye and Medical Study is a population-based study in rural Central India close to the tribal belt and included 4711 subjects (aged 30+ years). Depression was assessed by the Center for Epidemiologic Studies Depression Scale (CESD), suicidal ideation by six standardized questions, nicotine use by the Fagerstroem Nicotine Tolerance Questionnaire (FTNQ), and alcohol consumption by the Alcohol Use Disorders Identification Test (AUDIT). Results Mild to moderate depression (CESD sum score: 15–21) was detected in 1862 (39.6%) individuals (33.5% of men, 44.8 of women), and major depression (CESD sum score >21) in 613 (13.0%) individuals (8.1 of men, 17.3% of women). Suicide attempt was reported by 199 (4.2%) participants and suicidal thoughts during the last 6 months by 238 (5.1%) individuals. There were 887 (18.9%) smokers and smokeless tobacco was consumed by 1968 (41.8%) subjects. Alcohol consumption was reported by 1081 (23.0%) participants; 283 (6.0%) subjects had an AUDIT score ≥8 (hazardous drinking), and 108 (4.63%) subjects a score ≥13 (women) or ≥15 (men) (alcohol dependence). Conclusions In rural Central India, prevalence of major depression was comparable to figures reported from other developing countries. Prevalence of smoking and hazardous alcohol consumption was higher than as reported from urban regions. Measures should be taken to address the relatively high prevalence of suicide attempts and thoughts on suicide in rural Central India. PMID:25409441

    In this preliminary study the partitioning of rain-water into various components of the hydrological cycle in three high-altitude forests of contrasting tree physiognomies (namely, Aesculus indica, Quercus semecarpifolia and Abies pindrow) were studied in the Nandadevi Biosphere Reserve, Central Himalaya, India. The results are compared with the hydrological characteristics of low-altitude forests of this region. The study has indicated a significant role of tree physiognomy with regard to rainfall partitioning into the various components of the hydrological cycle. It is suggested that A. pindrow (an evergreen tree) should be considered superior to A. indica (a deciduous tree) with regard to soil and water conservation in this region. This work is of relevance to land management programmes pertaining to afforestation, logging and regeneration.

    Visual acuity is a major parameter for quality of vision and quality of life. Information on visual acuity and its associated factors in rural societies almost untouched by any industrialization is mostly non-available. It was, therefore, the purpose of our study to determine the distribution of visual acuity and its associated factors in a rural population not marked influenced by modern lifestyle. The population-based Central India Eye and Medical Study included 4711 subjects (aged 30+ years), who underwent a detailed ophthalmologic examination including visual acuity measurement. Visual acuity measurements were available for 4706 subjects with a mean age of 49.5±13.4 years (range: 30-100 years). BCVA decreased significantly (P<0.001) from the moderately hyperopic group (0.08±0.15 logMAR) to the emmetropic group (0.16±0.52 logMAR), the moderately myopic group (0.28±0.33 logMAR), the highly hyperopic group (0.66±0.62 logMAR) and finally the highly myopic group (1.32±0.92 logMAR). In multivariate analysis, BCVA was significantly associated with the systemic parameters of lower age (P<0.001), higher level of education (P<0.001), higher body stature (P<0.001) and higher body mass index (P<0.001), and with the ophthalmic parameters of more hyperopic refractive error (spherical equivalent) (P<0.001), shorter axial length (P<0.001), lower degree of nuclear cataract (P<0.001), and lower intraocular pressure (P = 0.006). The results suggest that in the rural population of Central India, major determinants of visual acuity were socioeconomic background, body stature and body mass index, age, refractive error, cataract and intraocular pressure.

    Morphometric analysis is significant for investigation and management of the watershed. This study depicts the morphometric analysis of Miniwada Watershed in Nagpur district, Maharashtra, Central India using Geographic Information System (GIS) techniques, which has been carried out through measurement of various aspects like linear, aerial and relief aspects of watershed. The drainage network of the watershed was generated from Cartosat-I DEM (10 m) using ESRI Software ArcGIS (ver.10.2). The analysis reveals that drainage pattern is dendritic and the stream order in the watershed varies from 1 to 4. The total number of stream segments of all orders counted as 37, out of which the majority of orders (70.27 %) was covered by 1st order streams and 4th order stream segments covers only 2.70 %. The bifurcation ratio reflects the geological and tectonic characteristics of the watershed and estimated as 3.08. The drainage density of the watershed is 3.63 km/sq km and it indicates the closeness of spacing of channels. The systematic analysis of various parameters in GIS helps in better understanding the soil resources distribution, watersheds prioritization, planning and management.

    The Deccan basalts in central western India are believed to occupy large onshore-offshore area. Using geophysical and geological observations, onshore sub-surface structural information has been widely reported. On the contrary, information about offshore structural variations has been inadequate due to scarcity of marine geophysical data and lack of onshore-offshore lithological correlations. Till date, merely a few geophysical studies are reported that gauge about the offshore extent of Deccan Traps and the Mesozoic sediments (pre-Deccan). To fill this gap in knowledge, in this article, we present new geophysical evidences to demonstrate offshore continuation of the Deccan volcanics and the Mesozoic sediments. The offshore multi-channel seismic and onshore-offshore lithological correlations presented here confirm that the Mesozoic sedimentary column in this region is overlain by 0.2-1.2-km-thick basaltic cover. Two separate phases of Mesozoic sedimentation, having very distinctive physical and lithological characteristics, are observed between overlying basaltic rocks and underlying Precambrian basement. Using onshore-offshore seismic and borehole data this study provides new insight into the extent of the Deccan basalts and the sub-basalt structures. This study brings out a much clearer picture than that was hitherto available about the offshore continuation of the Deccan Traps and the Mesozoic sediments of Kachchh. Further, its implications in identifying long-term storage of anthropogenic CO{sub 2} within sub-basalt targets are discussed. The carbon sequestration potential has been explored through the geological assessment in terms of the thickness of the strata as well as lithology.

    The Pithampur Industrial sectors I, II, and III, located approximately, 45 km from Indore in Central India have emerged as one of the largest industrial clusters in the region. Various types of industries ranging from automobiles to chemicals and pharmaceuticals have been set up in the region since 1990. Most of the industries have effluent treatment plants (ETP) for treating wastewater before its disposal on land and/or in water body. The present study is an attempt to assess the groundwater quality in the watersheds surrounding these industrial sectors to develop the baseline groundwater quality in order to enable the policy makers to facilitate decisions on the development of industries in this region. The industries are located in two sub-watersheds, namely, Gambhir river sub-watershed and Chambal river sub-watershed. Geologically, the study area is located in the Deccan traps of Cretaceous to Paleocene age. The different basaltic flow units underlie clayey soils varying in thickness from 2-3 m. The aquifer is mostly of unconfined nature. Samples have been collected from a network of observation wells set up in the watersheds. The water quality analysis of the groundwater samples has been carried out six times during three hydrological cycles of 2004, 2005, and 2006. The results indicate that a few observation wells in the vicinity of the industrial clusters have very high TDS concentration and exceed the Bureau of Indian Standards (BIS) guideline for TDS concentration. The contamination of groundwater has been more severe in the Gambhir watershed as compared to the Chambal watershed. The presence of the impermeable clay layers has resulted in a slow migration of contaminants from the sources. The findings reveal that there is no significant groundwater contamination in the Pithampur industrial sectors except in the vicinity of the industrial clusters, which indicates that there is good environmental space available for the expansion of industrial units in

    Seismic waveform data from 816 aftershocks of 2001 Bhuj Mw 7.7 earthquake, recorded by CERI/STAR aftershock deployment, including eight K2 6-channel dataloggers with 3-component episensor accelerometers and 3-component L-28 geophones, were used to develop a local magnitude scale for Kachchh basin of western India. Results show that the distance correction curve can be expressed as -logA0=1.8286*(r/100.0)-0.0052*(r-100.0)+3.0, displaying weak distance attenuation. This result is much like that of the local magnitude scale for the Central U.S. Both scales show weak distance attenuation, compared with the local magnitude scales for southern California or Tanzania, East Africa, and display a negative K parameter, implying similar patterns of seismic wave spreading in these two regions. These results for local magnitude scales give support to the assertion that the Kachchh basin and New Madrid Seismic Zone are geological analogs inasmuch that ground motion and other seismological results from one area can shed light on similar problems in the other area.

    Introduction: Hypomagnesemia has been common, but mostly underdiagnosed electrolyte abnormality. Studies regarding this is lacking in India especially in rural setting. Here, we have correlated serum magnesium (Mg) level with outcome in patients of medicine Intensive Care Unit (ICU) with respect to length of ICU stay, need for mechanical ventilatory support and its duration and ultimate outcome (discharge/death). Materials and Methods: This is a prospective observational study carried out over a period of 1-year enrolling 601 patients of Medical ICU (MICU). The Chi-square test is applied to correlate hypomagnesemia with the outcome. Result and Observation: About 25% patients had admission hypomagnesemia. When compared with the normal Mg group, there was significant association of hypomagnesemia with outcome in terms of duration of MICU stay 5.46 (5.75) versus 3.93 (3.88), need for mechanical ventilation (56.86% vs. 24.33%), discharge/cured from ICU (61.43% vs. 85.26%), and death (38.56% vs. 14.73%). However, no significant difference was found in the duration of ventilation between the two groups. Conclusion: Hypomagnesemia is associated with a higher mortality rate in critically ill patients. The need for ventilatory support, but not its duration is significantly higher in hypomagnesemic patients. Hypomagnesemia is commonly associated with sepsis and diabetes mellitus. The duration of MICU stay is significantly higher in patients with low serum Mg. PMID:26180429

    2013-01-01

    Background Artesunate + sulphadoxine-pyrimethamine (AS + SP) is recommended throughout India as the first-line treatment for uncomplicated falciparum malaria. Due to the presence of several eco-epidemiological zones of malaria and variable drug pressure, it is necessary to evaluate the efficacy of this combination in different regions of India. The objective of this study was to use clinical and molecular methods to monitor the efficacy of AS + SP in three diverse sites. Methods The study was undertaken in three high endemic sites of central and eastern India. Patients with uncomplicated falciparum malaria were enrolled and followed for 28 days. Molecular genotyping was conducted for merozoite surface protein (msp1 and msp2) to differentiate between re-infection and recrudescence and for the dhfr and dhps genes to monitor antifolate drug resistance. Results In all, 149 patients were enrolled at the three sites. The crude cure rates were 95.9%, 100%, and 100% in Ranchi, Keonjhar, and West Garo Hills respectively. PCR-corrected cure rates were 100% at all sites. In dhfr, 27% of isolates had triple mutations, while 46% isolates were double-mutants. The most prevalent mutation was S108N followed by C59R. 164 L mutation was observed in 43/126 (34%) isolates. In dhps, most (76%) of the isolates were wild-type. Only 2.5% (2/80) isolates showed double mutation. dhfr-dhps two locus mutation were observed in 16% (13/80) isolates. Parasite clearance time was not related with antifolate mutations. Conclusions AS + SP combination therapy remained effective against falciparum malaria despite common mutations promoting resistance to antifolate drugs. Although the prevalence of double and triple mutations in dhfr was high, the prevalence of dhfr-dhps two locus mutations were low. Even isolates with dhfr triple and dhfr-dhps two locus mutations achieved adequate clinical and parasitological response. PMID:23866298

    The regular onset of warm ocean temperatures off Peru during the calendar months of December and January has long been known as El Nino. Years with abnormally warm ocean surface temperatures along the Peruvian coast are associated with abnormally warm ocean surface temperatures up and down the Pacific coast. The changes in the equatorial Pacific ocean surface temperatures influence the distribution of precipitation and give rise to a pattern of abnormal surface pressures that spans the tropics, the Southern Oscillation. These two phenomena, i.e., El Nino and Southern oscillation combined are known as ENSO which emphasize the importance of the interaction between the oceans and atmosphere. It has been found that ENSO has a great influence on Indian summer monsoons. However, there are several studies to examine the influence of ENSO and sea surface temperatures (SST) on the quantum and distribution of monsoonal rainfall. It was observed that during the El Nino years the monsoonal rainfall gets reduced and causes drought conditions in some parts of India.

    Objective To explore and document the information regarding usage of ethnoveterinary medicinal plants utilized by rural farmers and traditional herbal healers for livestock healthcare in Tikamgarh District of Bundelkhnad, Central India. Methods The remote villages of Tikamgarh district were regularly visited from July 2011 to June 2012. Following the methods of Jain and Goel (1995) information regarding the usage of ethnoveterinary medicinal plants was collected. Results A total of 41 plant species in 39 genera and 25 families were used traditionally with various plant parts and their combinations for the treatment of more than 36 diseases in the studied area. Trees (17 species) were found to be the most used Ethnoveterinary medicinal plants followed by herbs (15 species), shrubs (6 species) and grasses (3) in descending order. The most common diseases cough, diarrhoea and fever were treated by 04 ethnoveterinary medicinal plant species. Conclusions The present study recommended that the crop and medicinal plant genetic resources cannot be conserved and protected without conserving/managing of the agro-ecosystem or natural habitat of medicinal plants and the socio-cultural organization of the local people. The same may be applied to protect indigenous knowledge, related to the use of medicinal and other wild plants. Introduction of medicinal plants in degraded government and common lands could be another option for promoting the rural economy together with environmental conservation, but has not received attention in the land rehabilitation programs in this region.

    Context: Lack of literature on psychological aspects of survivors of farmers' suicides is hurdle in devising effective helping strategies for rising number of survivors across the country. Aims and Objectives: To assess the psychological distress and its correlates in survivors of farmers' suicides. Settings and Design: Case–control study design was used in Wardha District of Vidarbha region in the central India. Materials and Methods: A predesigned and pretested semistructured questionnaire was used to assess sociodemographic variables. Self-Reporting Questionnaire-20 was used to evaluate psychological distress in 98 survivors of farmers' suicides and 98 age, sex, and occupation-matched controls. Statistical Analysis: Significance of differences between case and control groups were assessed using Chi-square test or Fisher's two-tailed exact test for class variables. For continuous variables, Student's t-test was used P < 0.05 was considered significant. Results: Significantly higher proportion of survivors had psychological distress than controls. Female survivors, spouse and parents of suicide victims had a high risk of distress. Psychological distress was commonly expressed by depressive and somatic symptoms. Conclusions: Survivors of farmers' suicides are suffering from significant psychological distress. PMID:27385846

    Mapping of subtrappean Mesozoic sediments is a complex geophysical problem faced by the oil industry world over which is of greater interest. Sediments underlying the traps are of varying thickness and causing considerable uncertainty in the interpretation of geophysical data. Deep Resistivity Sounding (DRS) technique is an effective non invasive electrical geophysical tool for delineation of the sub-trappean sediments up to a large depth (~ 3-4 km), due to marked resistivity contrast exist between the trap, sediment and basement. As a part of an integrated geophysical study, eighty-one deep resistivity soundings were conducted in the eastern part of Deccan flood basalt region, central India. The region is situated in the western part of the Indian subcontinent, which is covered by the Deccan traps, mostly exposed, except for a few places where thin Tertiary sediments are present. DRS data were acquired with Schlumberger electrode configuration up to a maximum current electrode separation of 10 km using high power deep resistivity equipment. The transmitter is capable of sending maximum current in the order of 20 A, and the receiver can measure signals in micro volts. Layer parameters i.e., resistivities and thicknesses of various layers have been determined from 1D modeling of all the eighty-one DRS stations. In order to explain the layered earth structure, geo-electric sections were prepared along few profiles and the results from two profiles showing maximum sediments are discussed in the present paper.

    Objective 1) To assess the adverse drug reactions (ADRs) of second-line anti-tubercular drugs used to treat Multi-drug resistant Tuberculosis (MDR-TB) in central India on the basis of causality, severity and avoidability scales. 2) To investigate the relationship of MDR-TB (primary or secondary) and the presence of diabetes mellitus (DM) with mean smear conversion time. Material and Methods: A prospective, observational study was carried out on diagnosed multidrug-resistant tuberculosis patients enrolled for DOTS-Plus regimen at TB and Chest Disease Department from January 2012 to December 2012 with a follow-up of nine months. Encountered ADRs were noted along with the time of sputum conversion. Results Total 64 ADRs were reported in 55 patients out of total 110 patients (n=110). As per the Naranjo causality assessment of ADRs, seven patients had definite, 45 had probable, and 3 had possible causal relation with drugs of DOTS-Plus regimen. As per the Hartwig’s severity assessment scale, there were total 7 ADRs in Level 1, 6 in Level 2, 33 in Level 3 and 9 in Level 4. Hallas avoidability assessment scale divided the ADRs as 3 being definitely avoidable, 26 possibly avoidable, 23 not avoidable and three not evaluable. Mean sputum smear conversion time was significantly higher in patients with a secondary type than that of primary type of MDR TB and in patients with DM than those without DM. Conclusion ADRs were common in patients of MDR-TB on DOTs-Plus drug regimen. It was due to lack of availability of safer and equally potent drugs in DOTs-Plus drug regimen compared to DOTS regimen in non-resistant TB. The frequency and severity of ADRs can be reduced by strict vigilance about known and unknown ADRs, monitoring their laboratory and clinical parameters and instituting appropriate measures.

    The present study included three groups: (A) age and gender matched control (n=24) with no previous signs of M. tuberculosis complex (MTBC) infection, (B) patients (n=28) diagnosed with gastro-intestinal TB (GITB), (C) patients (n=50) with clinical and histo-pathological signs of GITB, but were culture and AFB negative. Real time assay performed using fluorescence resonance energy transfer hybridization probes showed a positivity index of 36 % in group C, i.e. 18 were found reactive from the total 50 cases studied. In addition, immune characterization of these 18 cases showed depleted CD(4) (+) count and increased levels of IFN-γ and TNF-α cytokines. No positive case was found in group A, while in group B, out of total 28 cases studied 27 were found positive. A combinatorial diagnostic approach for rapid detection and characterization of GITB might provide specific therapeutic strategies for prevention and treatment of the infection in future.

    Background: Iron is the world's most commonly used metal and can usually be found with other elements in the form of steel. In this era of machines, it is the inevitable part in production of various materials like eyeglass frames, jet aircraft, the space shuttle, automobiles, and surgical instruments. Occupational factors make an important contribution to the global burden of disease, but the reliable data on occupational disease are much more difficult to obtain. Hence, the current study was carried out to find out the morbidity pattern among iron and steel workers Materials and Methods: A cross-sectional study. was carried out after obtaining permission from Institutional Ethics Committee in an iron and steel factory. Worker's detailed information regarding profile was taken in pretested questionnaire format after obtaining the informed written consent and explaining the purpose of study. Workers were also interviewed regarding their years of job, job satisfaction, usage of protective devices, and history of injuries during work. Worker's detailed general and systemic examination was conducted. Results: The overall prevalence of morbidities among the workers was 60%. It was observed that commonest morbidity in the workers was lumbago (musculoskeletal pain), that is, 33.25%which was more in Group B (49.73%) than Group A (18.78%), followed by occupational dermatitis (27%) which more common in Group A (33.33%) than Group B (19.79%). It was seen that occupation-related morbidities were more prevalent in Group A, i.e. Exposed group (P < 0.001). Conclusion: It was observed that occupation-related morbidities were more common in exposed group (EG) than that of nonexposed group (NEG) and the difference was found to be statistically significant (P < 0.001).

    To record the demographics, and correlate histological findings in central giant cell granulomas (CGCGs) of the jaws with their clinical behaviour, 30 paraffin-embedded samples of CGCG were retrieved from the archives of the Department of Oral Pathology and Microbiology, Subharti Dental College, Meerut, India. The diagnosis in each case was made on the basis of clinical, radiographic, and histological findings. Data about age, sex, anatomical site, presentation, radiological features, and laboratory investigations were analysed. Histomorphometric analyses were made in each case with respect to the number of giant cells, mean number of nuclei and giant cells, fractional surface area occupied by giant cells, index of relative size, and mitotic activity. The peak incidence of CGCG was during the second decade of life with a slight female predilection, and the mandible was the most common site. Of the 30 samples considered, 20 tumours were classified clinically as non-aggressive, and 10 as aggressive, based on their clinical behaviour. Histomorphometric analysis showed significant changes between the two groups with respect to the number of giant cells, the fractional surface area, and the mitotic activity. The data obtained showed clinical and histomorphometric features that may be reliable indicators for the differentiation between aggressive and non-aggressive CGCG. These data should be taken into consideration to improve planning of individual treatment and follow-up. PMID:22196146

    Grassland ecosystem is critical for survival of herbivores and plays an important role in conservation and management of wildlife. These habitats are widely studied for various issues, including biodiversity, biomass assessment, carrying capacity, etc. Woody species ingression in grasslands is one such important aspect that needs critical attention in protected area as this leads to shrinking of grasslands habitat. This study presents a case of Ronda grassland in Kanha National Park - a well-known protected area in India, known for its herbivore diversity and hard-ground Barasingha (Rucervus duvaceli branderi), in particular. Long-term satellite observation for five decades was carried out to understand spatio-temporal changes. Declassified Corona satellite data, aerial photographs along with satellite datasets in the subsequent period were utilised for this study. The study revealed that 88 ha (16% of Ronda and surrounding) have been ingressed during 1962-2011, in and around Ronda grassland of Kanha National Park. Rates of ingression on linear transects were found to be 60-120 m per decade. Field studies and NDVI analysis along the edge of grassland pixels as well as inside region using 1972 as baseline data, indicated woody vegetation replacing area of grassland. It was noted that Butea monosperma is invading more than other species in Ronda grassland, particularly along the stream where moisture availability is higher. Grassland habitats in Kanha are thus shrinking and thus leading to reduction in the area available for herbivore population which has increased in recent years. This can lead to severe impact on carrying capacity of these grasslands.

    Background & objectives: There is a paucity of data available on genetic biodiversity of Mycobacterium tuberculosis isolates from central India. The present study was carried out on isolates of M. tuberculosis cultured from diagnostic clinical samples of patients from Bhopal, central India, using spoligotyping as a method of molecular typing. Methods: DNA was extracted from 340 isolates of M. tuberculosis from culture, confirmed as M. tuberculosis by molecular and biochemical methods and subjected to spoligotyping. The results were compared with the international SITVIT2 database. Results: Sixty five different spoligo international type (SIT) patterns were observed. A total of 239 (70.3%) isolates could be clustered into 25 SITs. The Central Asian (CAS) and East African Indian (EAI) families were found to be the two major circulating families in this region. SIT26/CAS1_DEL was identified as the most predominant type, followed by SIT11/EAI3_IND and SIT288/CAS2. Forty (11.8%) unique (non-clustered) and 61 (17.9%) orphan isolates were identified in the study. There was no significant association of clustering with clinical and demographic characteristics of patients. Interpretation & conclusions: Well established SITs were found to be predominant in our study. SIT26/CAS1_DEL was the most predominant type. However, the occurrence of a substantial number of orphan isolates may indicate the presence of active spatial and temporal evolutionary dynamics within the isolates of M. tuberculosis.

    Objective: The aim of this study was to investigate the root and canal morphology of maxillary third molars in Central India population using cone-beam computed tomography (CBCT) analysis. Materials and Methods: CBCT images of 116 maxillary third molars were observed, and data regarding the number of roots, the number of canals, and Vertucci's Classification in each root was statistically evaluated. Results: Majority of Maxillary third molars had three roots (55.2%) and three canals (37.9%). Most MB root (43.8%), DB root (87.5%), and palatal root (100%) of maxillary third molars had Vertucci Type I. Mesiobuccal root of three-rooted maxillary third molars had Vertucci Type I (43.8%) and Type IV (40.6%) configuration. Overall prevalence of C-shaped canals in maxillary third molars was 3.4%. Conclusion: There was a high prevalence of three-rooted maxillary molars with three canals. PMID:27011747

    Background Tuberculosis (TB) and under-nutrition are widespread in many low and middle-income countries. Momentum to prioritize under-nutrition has been growing at an international level, as demonstrated by the "Scaling Up Nutrition" movement. Low body mass index is an important risk factor for developing TB disease. The objective of this study was to project future trends in TB related outcomes under different scenarios for reducing under-nutrition in the adult population in the Central Eastern states of India. Methods A compartmental TB transmission model stratified by body mass index was parameterized using national and regional data from India. We compared TB related mortality and incidence under several scenarios that represented a range of policies and programs designed to reduce the prevalence of under-nutrition, based on the experience and observed trends in similar countries. Results The modeled nutrition intervention scenarios brought about reductions in TB incidence and TB related mortality in the Central Eastern Indian states ranging from 43% to 71% and 40% to 68% respectively, relative to the scenario of no nutritional intervention. Modest reductions in under-nutrition averted 4.8 (95% UR 0.5, 17.1) million TB cases and 1.6 (95% UR 0.5, 5.2) million TB related deaths over a period of 20 years of intervention, relative to the scenario of no nutritional intervention. Complete elimination of under-nutrition in the Central Eastern states averted 9.4 (95% UR 1.5, 30.6) million TB cases and 3.2 (95% UR 0.7-, 10.1) million TB related deaths, relative to the scenario of no nutritional intervention. Conclusion Our study suggests that intervening on under-nutrition could have a substantial impact on TB incidence and mortality in areas with high prevalence of under-nutrition, even if only small gains in under-nutrition can be achieved. Focusing on under-nutrition may be an effective way to reduce both rates of TB and other diseases associated with under

    Background: Vitiligo is one of the common stigmatizing dermatosis in the Indian society and the vitiligo patients have to face significant psychological hurt and social neglect. The severity of the stigma is related to the society's attitude and knowledge about it. Aims and Objectives: To document the prevalent knowledge and attitude in general public towards vitiligo patients, and to identify the determinants of good/poor knowledge and attitude. Materials and Methods: A systematic random sampling technique was adopted to enroll 700 adult participants visiting an urban tertiary healthcare facility of central India. We developed a questionnaire to collect information on knowledge and attitude of the participants. A composite score was developed for good knowledge and attitude and performance of the participants was compared with the selected determinants. Data analysis was conducted by Stata software version 11. Results: The overall knowledge score was good for 66.3% (95% confidence interval [CI]: 62.8%, 69.8%) of the participants. However, the score for attitude was comparatively poor i.e., only 16.9% (95% CI: 13.9%, 19.5%). None of the studied parameters could be significantly correlated with the knowledge score. Being married and being engaged in a health care related occupation were significant predictors of good attitude levels with P = 0.042 and 0.034 respectively, whereas female gender was the significant predictor for poor attitude with an odds ratio of 0.54 (95% CI: 0.33, 0.9) and P = 0.018. Conclusions: There were widespread myths prevalent about vitiligo in the studied population. The knowledge scores were better than attitude scores. PMID:27003965

    CONTEXT: CD14 functions as a multifunctional receptor for bacterial cell wall components including endotoxin and lipopolysaccharide and is likely to influence the cytokine profile and subsequent immunoglobulin E production in response to antigen/allergen contact in allergic phenotypes. AIMS: The present study was to investigate genetic polymorphism in CD14 gene - 159C/T, which may be one of the risk factor for increased prevalence of Chronic Lung Diseases in the Central India. SETTINGS AND DESIGN: Survivors of Methyl isocyanates toxicity in Bhopal still suffering from various respiratory ailments were examined. MATERIALS AND METHODS: Polymerase chain reaction-restriction fragment length polymorphism was performed to determine the polymorphism of C-159T. RESULTS: The genotype and allelic frequencies were in Hardy-Weinberg’s equilibrium. Prevalence of CC, CT, and TT were 5.5%, 22.2% and 9.25% respectively in asthmatics; 16.6%, 20.3% and 5.5% respectively in chronic obstructive pulmonary disease (COPD) patients and 5.5%, 14.8% and 1.85 respectively among interstitial lung disorder (ILD) patients; whereas the control cohort with no methyl isocyanate exposure displayed (CC, CT, and TT) cytosine, thymine as 2%, 1.6% and 2% respectively. Increased risk of Asthma among those carrying TT genotype and T allele (odds ratio [OR] =2.61 and 2.02 respectively). CONCLUSION: COPD risk significantly found among those with CC genotype and C allele (OR = 2.81 and 1.50 respectively), whereas ILD risk found significantly among CT genotype and C allele (OR = 1.75 and 1.40 respectively). Therefore, single nucleotide polymorphism (SNP) C-159T polymorphism in CD14 gene might be a risk factor for development of CLD in this population. PMID:24019621

    Objective To study the prevalence of primary monosymptopomatic nocturnal enuresis (PMNE) in children aged 5–10 year and to find its association with sleep disordered breathing (SDB) by using a 22 item pediatric sleep related breathing disorder (SRBD) scale. Methods This was a school based cross sectional epidemiological study from July 2015 to November 2015. A questionnaire seeking information on socio-demographic variables, nocturnal enuresis (NE) frequency, school performance and a validated 22 item pediatric sleep related breathing disorder scale (SRBDs) was distributed to 1820 pupils in three primary schools. Results A total of 1528(83.95%) questionnaires were retrieved. Out of 1528 forms, 182(11.9%) forms were incomplete for requested information and hence 1346 (73.9%) questionnaires were finally analyzed. The prevalence of NE was found to be 12.7% (95% CI; 11–14.6), whereas prevalence of primary nocturnal enuresis (PMNE) was 8.2% (95% CI; 7.1–10.1). SRBD scale score >0.33 (adjusted OR: 2.87; 95%CI: 1.67–4.92), paternal history of enuresis in childhood (adjusted OR:4.96; 95% CI: 2.36–10.45), and inappropriate toilet training (adjusted OR: 1.64; 95% CI: 1.01–2.66) were independently associated with PMNE. Conclusion Sleep disordered breathing, inappropriate toilet training and a history of childhood NE in father were found to be significant risk factors for PMNE in the present study. Thus, these findings suggest that it is imperative to rule out SDB in PMNE patients as they may require different therapeutic interventions. PMID:27191620

    The use of processed arecanut is on the increase. In the impending danger of increased occurrence of oral submucous fibrosis and subsequent oral cancer following this habit is colossal. So an attempt is made to clinically evaluate the condition and to evaluate the effect of triamcinolone on this condition. Using the clinical data collected from the patients presenting in the ENT OPD of NSCB Medical College Hospital, Jabalpur, a cross sectional study was done and the effect of intralesional triamcinolone on this condition is noted by biweekly submucosal injections of 40 mg triamcinolone for 12 weeks and followed up for 1 year. The effect of therapy was evaluated subjectively by improvement in symptoms and objectively by increase in mouth opening. The age of occurrence and sex predilection also showed a significant change with more young males being affected by the condition. There was no significant correlation between effect of triamcinolone therapy and duration of addiction but a significant correlation (P < 0.0001) was noted with the frequency of addiction per day. A significant improvement in mouth opening is observed following local triamcinolone therapy. The results imply that the exposure and the frequency of chewing habits, and not mere the duration that is significant in producing the condition and affecting the treatment outcome. Local triamcinolone therapy has good effect in the initial stages of the disease. The fact that more youngsters are being affected needs serious consideration. PMID:23998027

    Two enhanced temperature-index (T-index) models are proposed by incorporating meteorological parameters viz. relative humidity, wind speed and net radiation. The models are an attempt to explore different climatic variables other than temperature affecting glacier surface melting. Weather data were recorded at Chorabari Glacier using an automatic weather station during the summers of 2010 (July 10 to September 10) and 2012 (June 10 to October 25). The modelled surface melt is validated against the measured point surface melting at the snout. Performance of the developed models is evaluated by comparing with basic temperature-index model and is quantified through different efficiency criteria. The results suggest that proposed models yield considerable improvement in surface melt simulation. Consequently, the study reveals that glacier surface melt depends not only on temperature but also on weather parameters viz. relative humidity, wind speed and net radiation play a significant role in glacier surface melting. This approach provides a major improvement on basic temperature-index method and offers an alternative to energy balance model.

    In the fall of 2002, GeoHazards International (GHI), a California-based nonprofit organization, launched two 3-year projects, each funded by the U.S. Agency for International Development, to improve the earthquake risk management of 23 cities in Central Asia and India. The objectives of these projects are to: * Assess the earthquake risk of each city, * Identify the most effective risk mitigation options for each city, * Raise awareness of that risk and those mitigation options, and * Initiate mitigation activities in some of these cities. A critical characteristic of these projects is that leaders of each local community will be deeply involved in realizing all four objectives. GHI will work with, in addition to local authorities, national government, academic and non-governmental organizations. In India, GHI’s partners are the Disaster Management Planning Hyogo Office, United Nations Centre for Regional Development (UNCRD) of Kobe, Japan, and the Sustainable Environment and Ecological Development Society (SEEDS), of Delhi, India. In India, we will work in 20 cities that were chosen, in a February 1, 2002 workshop (sponsored by Munich Reinsurance Company) in Delhi; the cities were selected by Indian earthquake professionals on the basis of the cities’ population, hazard, and economic, cultural and political significance. In Central Asia, we will focus on Tashkent, Uzbekistan; Dushanbe, Tadzhikistan; and Almaty, Kazakstan. GHI and its partners are looking for other organizations that would like to collaborate on these projects.

    Introduction: Burn injuries are a serious public health problem. In our study we have identified different epidemiological factors based on 10 years of our experience at a burn unit in central India and recommend some strategies to prevent burn injuries. Materials and Methods: This is a retrospective analysis (2001-2010) of database from burn unit of S.S. Medical College, Rewa, India. Results: 2499 patients with burn injury were analysed. 66.8% and 38.2% patients were females and males respectively, with a median age of 25 years. Flame (80.1%) was most common cause, home (96%) was most common place, traditional Indian stove (28.8%), kerosene lamp (26.7%), hot liquid (12.2%) and kerosene stove (10.4%) were common causes. Median Total Body Surface Area (TBSA) burn was 40.0%; females had significantly greater (P < 0.001) burn than males (median 50% vs 26.0%). High mortality (40.3%) seen; female sex (OR 3.22, 95% CI 2.65-3.92); young age (15-29 year) (OR 3.48, 95% CI 2.45-4.94); flame burn (OR 12.9, 95% CI 1.69-98.32); suicidal burn OR 6.82 95%CI 4.44-10.48) and TBSA > 76% (OR 3099, 95%CI 1302-7380) were significant risk factors for death. Median hospital stays was 8 days; shorter hospital stays seen among TBSA burn > 76% (2 days), suicidal intent (4 days), and those who expired (4 days). Septicemia (45.8%) and burn shock (41%) were the major cause for death. Conclusions: Cooking and lighting equipments are major cause of burn injury among females and young age group. Equipment modification to improve safety features and public awareness programs are necessary to reduce burn incidents. PMID:24678209

    Runoff water is an important transporting medium for various pollutants from land to surface water. Several mobiles and stationary sources such as vehicles, steel cement and thermal power plants, cooking, street, construction debris, etc. are emitting effluents in the environment of the central India. The rain runoff water washes out the air as well as land pollutants and flushes out into water bodies. Therefore, rain runoff water pollution in most urbanized and industrialized city of central India, i.e., Raipur during rainy season (May-September 2012) is analyzed statistically using cluster and principal component analysis to assess sources. The cluster analysis grouped runoff water samples into two clusters based on the similarity of runoff water quality characteristics of the total variance. The factor analysis differentiated the diffused sources of runoff water contaminants. The enrichment factors and runoff fluxes of the contaminants are discussed.

    The Malanjkhand granodiorite (MG) hosting economic copper mineralization and the hitherto barren Dongargarh granitoids (DG) have subtle differences in their petrographic and bulk geochemical features. The two plutons are contiguous and occur in the northern part of the Bhandara Craton in Central India with intervening volcanosedimentary sequence of the Dongargarh Supergroup amidst older gneisses. The Dongargarh granitoids studied in two smaller units have higher bulk magnetic susceptibility than the Cu-bearing MG; the majority of samples studied from the latter being ilmenite-series rocks. DG crystallized at higher pressures compared to MG. Plagioclase composition ranges from albite to high bytownite in MG, whereas its compositional range is restricted to high andesine in DG. However, both intrusions give identical temperature ranges estimated by binary feldspar thermometry. Biotite in MG shows higher Fe/Mg ratios, as well as a greater range of compositional variation, than that in DG. MG has a moderately fractionated rare earth element distribution pattern without any significant Eu anomaly, showing depletion in mid-range rare earth elements (REE) and no depletion in heavy REE. DG is characterized by a prominent negative Eu anomaly. Geochemical features indicate subtle differences in the nature of source rocks and/or melting processes responsible for the generation of the two granitoids. MG displays more consistent bulk chemical features and is possibly a result of crystallization from a homogeneous granodioritic melt. DG displays a greater diversity and possibly incorporated a significant felsic crustal component that contributed to the parent melt. A fluid inclusion study of quartz grains from the granitoids and barren quartz veins occurring in MG indicates identical low-temperature nature of the fluid in both cases. They differ from the fluid in the mineralized zone in MG in the absence of a high-temperature component and CO2 in the fluid. Late-stage fluids in

    Purpose: To test the hypothesis that taking translamina pressure difference into consideration changes associations between ocular perfusion pressure and glaucomatous optic neuropathy. Methods: The population-based Central India Eye and Medical Study included 4711 subjects. Ocular perfusion pressure was calculated as follows: ⅔ [diastolic blood pressure + ⅓ × (systolic blood pressure – diastolic blood pressure)] – IOP. Cerebrospinal fluid pressure (mm Hg) was estimated as follows: 0.44 body mass index (kg/m2) + 0.16 diastolic blood pressure (mm Hg) − 0.18 × age (years) − 1.91. Translamina pressure difference was IOP minus cerebrospinal fluid pressure. Results: In multivariate analysis, higher open-angle glaucoma prevalence was associaed with higher IOP (P<.001; odds ratio [OR], 1.19; 95% CI, 1.15, 1.24) or with higher translamina pressure difference (P<.001; OR, 1.15; 95% CI, 1.10, 1.19), but not with ocular perfusion pressure (P<.37). A smaller neuroretinal rim area was correlated with higher IOP (P<.001; standardized coefficient beta −0.09) or larger translamina pressure difference (P<.001; β −0.10), but not with ocular perfusion pressure (P=.26). Greater prevalence of angle-closure glaucoma was associated with higher IOP (P<.001; OR, 1.22; 95% CI, 1.15, 1.28) or higher translamina pressure difference (P<.001; OR, 1.19; 95% CI, 1.13, 1.25) or lower ocular perfusion pressure (P<.04; OR, 0.95; 95% CI, 0.90, 0.996). Correlation coefficients were highest for the association with IOP and lowest for ocular perfusion pressure. A smaller rim area was correlated with higher IOP (P<.001; beta −0.08) and higher translamina pressure difference (P<.001; beta −0.08); rim area and ocular perfusion pressure were not significantly associated (P=.25). Conclusions: The present study provides information on the relationship of translamina pressure difference to the development of optic nerve damage in what is presently called glaucoma. It does not provide

    Analysis of three years of data from a malaria clinic operated by the Indian Council of Medical Research (ICMR) in the Government Medical College Hospital in Jabalpur, central India, showed a high malaria prevalence among pregnant women, which was statistically highly significant (P < 0.0001) compared with the situation among nonpregnant women. Cerebral malaria was a common complication of severe Plasmodium falciparum infection, with a high mortality during pregnancy, requiring immediate attention. The study also showed that malaria infection was more frequent in primigravidae, falling progressively with increasing parity. Mean parasite densities were significantly higher in pregnant women compared with nonpregnant women for both P. falciparum (P < 0.001; df = 137) and P. vivax (P < 0.05; df = 72) infection. Pregnant women with falciparum or vivax malaria were significantly more anaemic than noninfected pregnant women or infected nonpregnant women. The average weight of 155 neonates from infected mothers was 350 g less than that of 175 neonates from noninfected mothers. This difference in birth weight was statistically significant for both P. falciparum (P < 0.0001; df = 278) and P. vivax (P < 0.0001; df = 223) infection. Congenital malaria was not recorded. We conclude that pregnant women from this geographical area require systematic intervention owing to their high susceptibility to malaria during pregnancy and the puerperium. PMID:10444880

    A study was carried out in Madhya Pradesh (Central India) to collect data on injury-causing agricultural incidents during the period 1995-1999. The overall incidence rate was 1.25/1000 workers/year. About 9.2% of the incidents were fatal, and most of the fatal incidents were due to tractors and snakebites (42.9% each). About 77.6% of all incidents were due to farm machinery, 11.8% were due to hand tools, and the remaining 10.6% were due to other sources like snakes, wells, etc. Data on 1,911 incidents reported in 10 leading newspapers published during the five-year period (1995-1999) from different regions of the state were also collected and analyzed, which indicated that only major or roadside agricultural incidents were reported in newspapers. Based on the survey data, it was estimated that in the year 2000 there would have been about 17,480 agricultural incidents in Madhya Pradesh, causing death to about 2,050 workers and injuries to about 16,770 workers, including amputations of limbs, burns, cuts, etc. Total monetary loss due to agricultural injuries in the state of Madhya Pradesh has been estimated as US $27 million/year.

    Variation of soil moisture during active and weak phases of summer monsoon JJAS (June, July, August, and September) is very important for sustenance of the crop and subsequent crop yield. As in situ observations of soil moisture are few or not available, researchers use data derived from remote sensing satellites or global reanalysis. This study documents the intercomparison of soil moisture from remotely sensed and reanalyses during dry spells within monsoon seasons in central India and central Myanmar. Soil moisture data from the European Space Agency (ESA)—Climate Change Initiative (CCI) has been treated as observed data and was compared against soil moisture data from the ECMWF reanalysis-Interim (ERA-I) and the climate forecast system reanalysis (CFSR) for the period of 2002-2011. The ESA soil moisture correlates rather well with observed gridded rainfall. The ESA data indicates that soil moisture increases over India from west to east and from north to south during monsoon season. The ERA-I overestimates the soil moisture over India, while the CFSR soil moisture agrees well with the remotely sensed observation (ESA). Over Myanmar, both the reanalysis overestimate soil moisture values and the ERA-I soil moisture does not show much variability from year to year. Day-to-day variations of soil moisture in central India and central Myanmar during weak monsoon conditions indicate that, because of the rainfall deficiency, the observed (ESA) and the CFSR soil moisture values are reduced up to 0.1 m3/m3 compared to climatological values of more than 0.35 m3/m3. This reduction is not seen in the ERA-I data. Therefore, soil moisture from the CFSR is closer to the ESA observed soil moisture than that from the ERA-I during weak phases of monsoon in the study region.

    Background: Anopheles culicifacies is an important vector of malaria in Southeast Asia, contributing to almost 70% of malaria cases in India. It exists as a complex of five morphologically indistinguishable species A, B, C, D and E with varied geographical distribution patterns. In India, 8% of the total population of Madhya Pradesh (Central India) contributes about 30% of total malaria cases, 60% of total falciparum cases and 50% of malaria deaths. An. culicifacies is the major malaria vector in this state. Vector control mainly relies on the proper identification and distribution of vector species exists in a particular area. The present study was carried out to identify the distribution of An. culicifacies sibling species in certain endemic district of Central India, Madhya Pradesh. Methods: The An. culicifacies mosquitoes collected from the study districts were identified morphologically. The genomic DNA was isolated from the mosquitoes and subjected to Allele specific PCR targeting D3 domain of 28S ribosomal DNA. Results: The mean prevalence of An. culicifacies during the study period was in the range of 8–120 per man per hour (PMH). From the study areas species B was identified from Jabalpur, Chindwara and Hoshangabad, Species C from Hoshangabad only, Species D from Narsinghpur and Khandwa and sibling species E from Mandla, Chindwara and Hoshangabad respectively. Conclusion: This is the first report to detect species E from Madhya Pradesh region which necessitate for reconsideration of species distribution of each An. culicifacies sibling species that would enable to develop required vector control strategies.

    Deccan intertrappean sediments in central India are generally considered as terrestrial deposits of Maastrichtian age, but the Cretaceous-Tertiary (K-T) position is still unknown. Here we report the discovery of the K-T transition, a marine incursion and environmental changes preserved within the intertrappean sediments at Jhilmili, Chhindwara District, Madhya Pradesh. Integrative biostratigraphic, sedimentologic, mineralogic and chemostratigraphic analyses reveal the basal Danian in the intertrappean sediments between lower and upper trap basalts that regionally correspond to C29r and the C29R/C29N transition, respectively. Intertrappean deposition occurred in predominantly terrestrial semi-humid to arid environments. But a short aquatic interval of fresh water ponds and lakes followed by shallow coastal marine conditions with brackish marine ostracods and early Danian zone P1a planktic foraminifera mark this interval very close to the K-T boundary. This marine incursion marks the existence of a nearby seaway, probably extending inland from the west through the Narmada and Tapti rift valleys. The Jhilmili results thus identify the K-T boundary near the end of the main phase of Deccan eruptions and indicate that a major seaway extended at least 800 km across 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

    Aeromonads are ubiquitous foodborne pathogens with a global distribution. Animal-origin foods and contaminated animals are the main sources of Aeromonas infection to humans. So far little is known about the occurrence of Aeromonas spp. in food-producing animals in India. The present study was conducted to determine the prevalence and seroprevalence of Aeromonas species from 50 each of meat, blood, and sera samples collected from cattle, buffaloes, goats, and pigs slaughtered in and around Nagpur, Central India. Alkaline peptone water and ampicillin dextrin agar were used to isolate Aeromonas spp. An indirect enzyme-linked immunosorbent assay (ELISA) was standardized by use of whole-cell antigen (WC) and outer membrane protein (OMP) of Aeromonas hydrophila (MTCC 646). Aeromonads were isolated from 44 (22%) of the meat samples, and 1 (0.5%) from the blood samples. Seroprevalence by indirect ELISA-based WC antigen was estimated as 68% in cattle, 44% in buffaloes, 60% in goats, and 30% in pigs. OMP-based ELISA yielded a seroprevalence of 56%, 48%, 52%, and 22% in cattle, buffaloes, goats, and pigs, respectively. The results revealed that OMP-based ELISA and WC-based ELISA were in agreement with one another. Isolation along with high seropositivity demonstrates the presence of foodborne Aeromonas spp. in the Nagpur city of Central India. PMID:25946095

    Introduction: Although diarrheal diseases with known etiologies are under regular surveillance by the integrated disease surveillance project in India, only limited food-borne outbreaks were subjected to systematic epidemiological investigation. We examined one incidence of a food-borne outbreak among medical students in Bhopal, India, to identifying the source and mode of transmission, and to implement appropriate preventive measures. Materials and Methods: We constituted two teams. We did the line listing, filled the structured questionnaire and collected the biological samples. We did in-depth interviews of the case patients. We interviewed food handlers in mess. We randomly collected food and water samples. Results: The study results identified 30 hosteller case patients for a total of 239 students (overall attack rate [AR]: 12.6%). In female students, the AR was 18.1% and in the male students it was 6.7%. The AR was highest in female hostel no. One compared to other female and male hostel (19.8% vs. 14.3%, 6.7%). We identified four different risk factors for the illness. Discussion: As AR s are high compared to the general population. As the AR was high among the girls, the probable source of infection resides in the female hostel. PMID:26604614

    Objective Obesity is a growing problem in India, dietary determinants of which have been studied using an ‘individual food/nutrient’ approach. Examining dietary patterns may provide more coherent findings, but few studies in developing countries have adopted this approach. This study aimed to identify dietary patterns in an Indian population and assess their relationship with anthropometric risk factors. Design Food Frequency Questionnaire data from the cross-sectional sib-pair Indian Migration Study (IMS) (n=7067), was used to identify dietary patterns using principal component analysis. Mixed-effects logistic regression was used to examine associations with obesity and central obesity. Setting IMS was conducted at four factory locations across India: Lucknow, Nagpur, Hyderabad, Bangalore. Subjects The participants were rural-to-urban migrant and urban non-migrant factory workers, their rural and urban resident siblings, and their co-resident spouses. Results Three dietary patterns were identified, ‘cereals-savoury foods’ (cooked grains, rice/rice-based dishes, snacks, condiments, soups, nuts), ‘fruit-veg-sweets-snacks’ (western cereals, vegetables, fruit, fruit juices, cooked milk products, snacks, sugars, sweets), and ‘animal-food’ (red meat, poultry, fish/seafood, eggs). In adjusted analysis, positive graded associations were found between the ‘animal-food’ pattern and both anthropometric risk factors. Moderate intake of the ‘cereals-savoury foods’ pattern was associated with reduced odds of obesity and central obesity. Conclusion Distinct dietary patterns were identified in a large Indian sample, which were different from those identified in previous literature. A clear ‘plant-based/animal food-based pattern’ dichotomy emerged, with the latter being associated with higher odds of anthropometric risk factors. Longitudinal studies are needed to further clarify this relationship in India. PMID:25697609

    India is known for its historic diamonds from alluvial gravels. The source rocks for these diamonds are thought to be among the so far nearly 100 identified kimberlitic/lamproitic pipes and dikes which occur mostly in the Dharwar craton (Andhra Pradesh) and the Bundelkhand craton (Madhya Pradesh), and which all have Mesoproterozoic ages with a peak at 1.1 Ga. However, diamondiferous kimberlite pipes in the recently discovered Mainpur kimberlite field in central India have surprisingly young 40Ar/39Ar whole-rock ages of 66.5 ±2.0 and 62.4 ±2.9 million years (2σ), confirmed by more precise laser ablation ICP-MS 206Pb/238U perovskite data of 65.1 ±0.8 and 62.3 ±0.8 Ma (2 σ). These ages overlap with the main phase of the Deccan flood basalt magmatism at 65 million years, and suggest a common tectonomagmatic control for both flood basalts (including carbonatite-alkaline rock variants) and kimberlites. The kimberlites were studied in drill core and have textural, bulk and mineral chemical composition typical of orangeite (African kimberlite Group 2), confirmed by Sr and Nd isotope data. The Mainpur kimberlite field is in the Archean Bastar craton with felsic rocks as old as 3.6 Ga. The presence of macrodiamonds in the pipes implies that Central India had a cool and thick lithospheric mantle root at the Cretaceous/Tertiary boundary, significantly different from the modern Indian lithosphere of about 80-100 km thickness only. The loss of India's cratonic roots must have taken place in the Tertiary, i.e. after much of the superfast northward motion of the Indian plate from Gondwana break-up at about 130 million years until the collision with Eurasia at about 50 million years ago. India's unique plate-tectonic behaviour in the Cretaceous cannot be related to a plume-eroded lithosphere. About one third of the Indian lithosphere was lost during or after the Deccan flood basalt event.

    Aim: To understand the dental health among prison inmates, we assessed the dental caries status of central prison inmates in Chennai, India. Materials and Methods: A total of 1060 inmates from three divisions of the central prison in Chennai were assessed by a single investigator for dental caries status based on World Health Organization specifications. Results: Among the inmates, 58.2% of males and 54.2% of females had decayed teeth. About 4.1% of males and 2.9% of females had filled teeth. The mean decayed, missing, filled teeth index was 5.1 and 3.9 for female and male prisoners, respectively. The prevalence of dental caries was highest among inmates younger than 24 years age. Conclusion: Our study suggests that a high proportion of prison inmates was affected by dental caries, which necessitates the need for initiating oral health promotion activities among prison inmates.

    Weakening of the rocks is pronounced during the formation of shear zone. Crustal scale shear zones at the plate boundary develop due to grain size reduction, either by mechanical breakdown of minerals or by the development of new minerals due to change in pressure (P) - temperature (T) conditions. In either of the mechanisms for grain size reduction, the Gibb's free energy of the system should be minimum in value to stabilize the mineral.In this contribution, we have studied the deformation mechanism and P-T conditions from acrustal scale shear zone, in the North Central Part of Archaean Bundelkhand Craton. In the Archaean Buldelkhand craton, tens of kilometre wide E-W trending shear zone developed in the sodic-potassic granite. The undeformed rock (protolith) is characterized by euhedral to subhedral sodic feldspar (XAb =0.80) and subordinate quartz, whereas the deformed rock is characterized by the development of extremely deformed feldspar and quartz associated with chlorite. The onset of the strain localization and shear zone formation in the proto-mylonite has been accompanied by developing brittle fractures in the euhedral feldspar grains. In contrast to the brittle deformation in feldspar, quartz grains are characterized by development of small bulges around the grain boundary. Chlorite develops at the fractures in the feldspar that are indicative of fluid infiltration in the proto-mylonite.In the extremely deformed samples (ultramylonite) grain size reduction occurs by bulging recrystallization in quartz. Flow stress obtained from grain size analysis of quartz indicates that the palaeo-stress varies from ~44-46 MPa in proto-mylonite to ~ 61-63 MPa in Ultra-mylonite. Mineral chemical analysis of undeformed feldspar grains in the protolith and mylonite indicate significant changes in the chemical composition that leads to minimum Gibbs energy. Also the presence of chlorite indicates hydration reaction, which has reduced the chemical energy of the system

    Background Sickle cell disease (SCD) is a major health burden in India. The objective of the study was to establish a neonatal screening program and to understand the clinical course of children with SCD in central India. Methods and Findings Pregnant mothers were screened for sickle hemoglobin using the solubility test. Babies were screened by high performance liquid chromatography if the mother was positive for sickle hemoglobin. The diagnosis was confirmed by molecular analysis. They received early prophylactic treatment and vaccination. Of 2134 newborns screened, 104 were sickle homozygous (SS), seven had sickle β-thalassemia (S-β thal) and 978 were sickle heterozygous (AS). The other hemoglobin abnormalities detected included HbS -δβ thalassemia-1, HbSD disease-2, HbE traits-5, β-thalassemia traits-4, alpha chain variants-3 and HbH disease-1.These babies were followed up regularly for hematological and clinical evaluation. Pain, severe anemia requiring blood transfusions and acute febrile illness were the major complications with 59.7, 45.1 and 42.6 cases per 100 person years. Fetal hemoglobin (HbF) levels were inversely associated with vaso-oclussive crisis (VOC) and severe anemia while presence of alpha thalassemia increased the rate of painful events and sepsis. Six early deaths occurred among the SS babies. Conclusion A systematic follow up of this first newborn SCD cohort in central India showed that 47% of babies presented within 1 year of age. In spite of the presence of the Arab-Indian haplotype many babies had severe manifestations. PMID:26785407

  13. Comparison of large central and small decentralized power generation in India

    SciTech Connect

    1997-05-01

    This reports evaluates two options for providing reliable power to rural areas in India. The benefits and costs are compared for biomass based distributed generation (DG) systems versus a 1200-MW central grid coal-fired power plant. The biomass based DG systems are examined both as alternatives to grid extension and as supplements to central grid power. The benefits are divided into three categories: those associated with providing reliable power from any source, those associated specifically with biomass based DG technology, and benefits of a central grid coal plant. The report compares the estimated delivered costs of electricity from the DG systems to those of the central plant. The analysis includes estimates for a central grid coal plant and four potential DG system technologies: Stirling engines, direct-fired combustion turbines, fuel cells, and biomass integrated gasification combined cycles. The report also discusses issues affecting India`s rural electricity demand, including economic development, power reliability, and environmental concerns. The results of the costs of electricity comparison between the biomass DG systems and the coal-fired central grid station demonstrated that the DG technologies may be able to produce very competitively priced electricity by the start of the next century. The use of DG technology may provide a practical means of addressing many rural electricity issues that India will face in the future. Biomass DG technologies in particular offer unique advantages for the environment and for economic development that will make them especially attractive. 58 refs., 31 figs.

    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.

    The problem of environmental contamination by persistent chlorinated pesticides still evokes major concern due to the presence of their residues in the environment and in human tissues. In developing countries like India organochlorine insecticides, especially DDT are extensively being used in agriculture and vector control programs. Few data are available on their levels of concentration from the seas around India. Persistent pesticides residues can be expected to accumulate in marine sediments. However, very little data on this are available along the Indian coast. An attempt has been made in the present communication to identify and quantify some of the chlorinated pesticides residues in the marine sediments collected from different region along the central west coast of India. This is a part of our ongoing project to monitor and map pollutants within the exclusive economic zone of India.

This work is also an attempt to present a list of animals' use for medicinal purposes by different communities of India. Data were gathered from 15 published research papers of various authors on zootherapeutic studies in India from 2000 to 2007. Approximately 109 animals and their 270 uses are reported in traditional medicine in different parts of India. Of these, the highest numbers of animal species (42, 38.5%) with 50 (18.5%) uses have been reported for the treatment of Respiratory system related problems. Rheumatic and other pains are treated with 32 species (29.4%) in 34 (12.9%) uses. Gastric problems are reported to be treated with 22 (20.2%) species in 26 (9.9%) uses. The mammals constitute the highest number of animals used for medicinal purposes. 44 (40%) mammals, 24 (22%) invertebrates, 18 (17%) birds, 12 (11%) reptiles, nine (8%) fishes and two (2%) amphibians have been reported for medicinal purposes. Of the total 109 animal species reported, 76(70%) are included in IUCN red data list and 36 (33%) animal species are listed in CITES appendix I, II, and III. This work will be helpful in biodiversity conservation in India and also give a clue to investigate bio-active compound in these animal raw materials. PMID:18634551

    Sickle cell disease is an inherited disorder of the blood, and characterized by vasoocclusive crises (VOC), risks for pneumococcal infections and organ toxicities, is associated with morbidity and premature mortality. India, with a population of 1.2 billion individuals, is estimated to be home to over 50.0% of the world's patients with sickle cell disease. The β(S) gene [β6(A3)Glu→Val; HBB: c.20A>T] has the highest prevalence in three socio-economically disadvantaged ethnic categories: the Scheduled Castes (SC), the Scheduled Tribes (ST), and Other Backward Class (OBC) groups in India. The tradition of endogamy practiced by the ethnic groups in India provides the rationale for the screening of individual populations to better understand the distribution of the β(S) gene, guide counseling and awareness programs and aid development of public policy. We undertook a study to describe the prevalence of the β(S) gene in these ethnic groups in the district of Nagpur, Maharashtra in Central India. Through community screening and subsequent targeted screening of high risk individuals, 35,636 individuals were screened, of whom 5466 were found to have sickle cell trait and 1010 were identified with sickle cell disease. Community screening revealed a sickle cell trait prevalence of 13.0% in the SC, 12.0% in the ST and 3.4% in the OBC population. This study describes the prevalence of the β(S) gene within these groups in Central India determined by large scale community screening. This program has uncovered previously undiagnosed cases, provided detailed information to guide population-based disease counseling, prevention and comprehensive care programs. PMID:25023085

    Understanding the patterns of gene flow of an endangered species metapopulation occupying a fragmented habitat is crucial for landscape-level conservation planning and devising effective conservation strategies. Tigers (Panthera tigris) are globally endangered and their populations are highly fragmented and exist in a few isolated metapopulations across their range. We used multi-locus genotypic data from 273 individual tigers (Panthera tigris tigris) from four tiger populations of the Satpura–Maikal landscape of central India to determine whether the corridors in this landscape are functional. This 45 000 km2 landscape contains 17% of India's tiger population and 12% of its tiger habitat. We applied Bayesian and coalescent-based analyses to estimate contemporary and historical gene flow among these populations and to infer their evolutionary history. We found that the tiger metapopulation in central India has high rates of historical and contemporary gene flow. The tests for population history reveal that tigers populated central India about 10 000 years ago. Their population subdivision began about 1000 years ago and accelerated about 200 years ago owing to habitat fragmentation, leading to four spatially separated populations. These four populations have been in migration–drift equilibrium maintained by high gene flow. We found the highest rates of contemporary gene flow in populations that are connected by forest corridors. This information is highly relevant to conservation practitioners and policy makers, because deforestation, road widening and mining are imminent threats to these corridors. PMID:23902910

    Background Acute encephalitis syndrome (AES) is a constellation of symptoms that includes fever and altered mental status. Most cases are attributed to viral encephalitis (VE), occurring either in outbreaks or sporadically. We conducted hospital-based surveillance for sporadic adult-AES in rural Central India in order to describe its incidence, spatial and temporal distribution, clinical profile, etiology and predictors of mortality. Methods All consecutive hospital admissions during the study period were screened to identify adult-AES cases and were followed until 30-days of hospitalization. We estimated incidence by administrative sub-division of residence and described the temporal distribution of cases. We performed viral diagnostic studies on cerebrospinal fluid (CSF) samples to determine the etiology of AES. The diagnostic tests included RT-PCR (for enteroviruses, HSV 1 and 2), conventional PCR (for flaviviruses), CSF IgM capture ELISA (for Japanese encephalitis virus, dengue, West Nile virus, Varicella zoster virus, measles, and mumps). We compared demographic and clinical variables across etiologic subtypes and estimated predictors of 30-day mortality. Results A total of 183 AES cases were identified between January and October 2007, representing 2.38% of all admissions. The incidence of adult AES in the administrative subdivisions closest to the hospital was 16 per 100,000. Of the 183 cases, a non-viral etiology was confirmed in 31 (16.9%) and the remaining 152 were considered as VE suspects. Of the VE suspects, we could confirm a viral etiology in 31 cases: 17 (11.2%) enterovirus; 8 (5.2%) flavivirus; 3 (1.9%) Varicella zoster; 1 (0.6%) herpesvirus; and 2 (1.3%) mixed etiology); the etiology remained unknown in remaining 121 (79.6%) cases. 53 (36%) of the AES patients died; the case fatality proportion was similar in patients with a confirmed and unknown viral etiology (45.1 and 33.6% respectively).

    Background A prospective study on severe and complicated malaria was undertaken in the tribal dominated area of Bastar division, Chhattisgarh (CG), Central India, with an objective to understand the clinical epidemiology of complicated malaria in patients attending at a referral hospital. Methods Blood smears, collected from the general medicine and pediatric wards of a government tertiary health care facility located in Jagdalpur, CG, were microscopically examined for malaria parasite from July 2010 to December 2013. The Plasmodium falciparum positive malaria cases who met enrollment criteria and provided written informed consent were enrolled under different malaria categories following WHO guidelines. PCR was performed to reconfirm the presence of P.falciparum mono infection among enrolled cases. Univariate and multivariate logistic regression analysis was done to identify different risk factors using STATA 11.0. Results A total of 40,924 cases were screened for malaria. The prevalence of malaria and P.falciparum associated complicated malaria (severe and cerebral both) in the hospital was 6% and 0.81%, respectively. P.falciparum malaria prevalence, severity and associated mortality in this region peaked at the age of>4–5 years and declined with increasing age. P.falciparum malaria was significantly more prevalent in children than adults (P<0.00001). Among adults, males had significantly more P.falciparum malaria than females (P<0.00001). Case fatality rate due to cerebral malaria and severe malaria was, respectively, 32% and 9% among PCR confirmed mono P.falciparum cases. Coma was the only independent predictor of mortality in multivariate regression analysis. Mortality was significantly associated with multi-organ complication score (P = 0.0003). Conclusion This study has revealed that the pattern of morbidity and mortality in this part of India is very different from earlier reported studies from India. We find that the peak morbidity and mortality in

    Tribals are the most marginalised social category in the country and there is little and scattered information on the actual burden and pattern of illnesses they suffer from. This study provides information on burden and pattern of diseases among tribals, and whether these can be linked to their nutritional status, especially in particularly vulnerable tribal groups (PVTG) seen at a community health programme being run in the tribal areas of Chhattisgarh and Madhya Pradesh States of India. This community based programme, known as Jan Swasthya Sahyog (JSS) has been serving people in over 2500 villages in rural central India. It was found that the tribals had significantly higher proportion of all tuberculosis, sputum positive tuberculosis, severe hypertension, illnesses that require major surgery as a primary therapeutic intervention and cancers than non tribals. The proportions of people with rheumatic heart disease, sickle cell disease and epilepsy were not significantly different between different social groups. Nutritional levels of tribals were poor. Tribals in central India suffer a disproportionate burden of both communicable and non communicable diseases amidst worrisome levels of undernutrition. There is a need for universal health coverage with preferential care for the tribals, especially those belonging to the PVTG. Further, the high level of undernutrition demands a more augmented and universal Public Distribution System. PMID:26139787

    2012-01-01

    Background Malaria continues to be a significant health problem in India. Several of the intended Plasmodium falciparum vaccine candidate antigens are highly polymorphic. The genetic diversity of P. falciparum merozoite surface protein-1 (MSP-1) has been extensively studied from various parts of the world. However, limited data are available from India. The aim of the present study was a molecular characterization of block 2 region of MSP-1 gene from the tribal-dominated, forested region of Madhya Pradesh. Methods DNA sequencing analysis was carried out in 71 field isolates collected between July 2005 to November 2005 and in 98 field isolates collected from July 2009 to December 2009. Alleles identified by DNA sequencing were aligned with the strain 3D7 and polymorphism analysis was done by using Edit Sequence tool (DNASTAR). Results The malaria positivity was 26% in 2005, which rose to 29% in 2009 and P. falciparum prevalence was also increased from 72% in 2005 to 81% in 2009. The overall allelic prevalence was higher in K1 (51%) followed by MAD20 (28%) and RO33 (21%) in 2005 while in 2009, RO33 was highest (40%) followed by K1 (36%) and MAD20 (24%). Conclusions The present study reports extensive genetic variations and dynamic evolution of block 2 region of MSP-1 in central India. Characterization of antigenic diversity in vaccine candidate antigens are valuable for future vaccine trials as well as understanding the population dynamics of P. falciparum parasites in this area.

    Since the 80's, numerous authors have established the connection between Deccan volcanism in India and the KT events. Chenet et al (2008) showed that Deccan Traps erupted in three main phases with 6% total Deccan volume in phase-1 (base C30n), 80% in phase-2 (C29r) and 14% in phase-3 (C29n). Recent works indicate that the main phase-2 (80%) occurred over a relatively short time interval in magnetic polarity C29r, which coincides with the KTB events (Blair et al., in press, Keller et al, 2012). The biotic evolution is well understood in marine environments, but only few data are available concerning the terrestrial environmental changes. In central India, sedimentary beds associated with the Deccan Traps are represented by infratrappean (Lameta Formation) and intertrappean sediments, which were deposited during periods of volcanic quiescence. These deposits are located at different stratigraphic levels within the basaltic pile and are therefore crucial to evaluate the changes on land induced by the onset of the volcanism. The sedimentary beds exposed in the central part of India in the Jabalpur-Mandla-Chhindwara sector (Madyha Pradesh) and in the Nand-Dongargaon basin (Maharashtra) were studied using a sedimentological, geophysical, geochemical and mineralogical approach. Our results indicate that the intertrappean sediments deposited during the Deccan volcanism do not reflect the same characteristics than the infratrappean sediments preceding the volcanic eruptions. Indeed, palynological studies of the Lameta Formation indicate a dominance of angiosperms and a rich canopy of gymnosperms (Conifers and Podocarpaceae) and an understory of palms and herbs. Moreover, sedimentological and mineralogical observations indicate alluvial-limnic environment under arid climate. The eruption of Deccan volcanic flows severely affected the environmental conditions. Intertrappean sediments associated with the three Deccan phases were deposited in terrestrial to lacustrine

    In this study, downscaling models were developed for the projections of monthly maximum and minimum air temperature for three stations, namely, Allahabad, Satna, and Rewa in Tons River basin, which is a sub-basin of the Ganges River in Central India. The three downscaling techniques, namely, multiple linear regression (MLR), artificial neural network (ANN), and least square support vector machine (LS-SVM), were used for the development of models, and best identified model was used for simulations of future predictand (temperature) using third-generation Canadian Coupled Global Climate Model (CGCM3) simulation of A2 emission scenario for the period 2001-2100. The performance of the models was evaluated based on four statistical performance indicators. To reduce the bias in monthly projected temperature series, bias correction technique was employed. The results show that all the models are able to simulate temperature; however, LS-SVM models perform slightly better than ANN and MLR. The best identified LS-SVM models are then employed to project future temperature. The results of future projections show the increasing trends in maximum and minimum temperature for A2 scenario. Further, it is observed that minimum temperature will increase at greater rate than maximum temperature.

    Objective. To detect genes encoding carbapenem resistance among Enterobacter species in a tertiary care hospital in central India. Methods. Bacterial identification of Enterobacter spp. isolates from various clinical specimens in patients admitted to intensive care units was performed by routine conventional microbial culture and biochemical tests using standard recommended techniques. Antibiotic sensitivity test was performed by standard Kirby Bauer disc diffusion technique. PCR amplification and automated sequencing was carried out. Transfer of resistance genes was determined by conjugation. Results. A total of 70/130 (53.84%) isolates of Enterobacter spp. were found to exhibit reduced susceptibility to imipenem (diameter of zones of inhibition ≤13 mm) by disc diffusion method. Among 70 isolates tested, 48 (68.57%) isolates showed MIC values for imipenem and meropenem ranging from 32 to 64 mg/L as per CLSI breakpoints. All of these 70 isolates were found susceptible to colistin in vitro as per MIC breakpoints (<0.5 mg/L). PCR carried out on these 48 MBL (IP/IPI) E-test positive isolates (12 Enterobacter aerogenes, 31 Enterobacter cloacae, and 05 Enterobacter cloacae complex) was validated by sequencing for beta-lactam resistance genes and result was interpreted accordingly. Conclusion. The study showed MBL production as an important mechanism in carbapenem resistance in Enterobacter spp. and interspecies transfer of these genes through plasmids suggesting early detection by molecular methods.

    A cross sectional study was conducted to determine the prevalence of intestinal parasitic infections and its epidemiological correlates among rural Indian school going children and to find out the effect of hygiene education on personal hygiene of school children at village Karanji (Kaji) in Wardha district of central India. Out of 172, 87 (50.6%) boys and 85 (49.4%) girls were examined. The mean age of the school children was 10.37 +/- 2.71. The prevalence of intestinal parasite infection was 7.56%. The prevalence was significantly high among barefoot children (OR = 8.99; 95% CI: 2.14 - 43.49) followed by those having poor hand washing practices (OR = 4.90; 95% CI: 1.30 - 20.01), not using sanitary latrine (OR = 2.49; 95% CI: 0.6 - 11.91)) and dirty untrimmed nails (OR = 1.98; 95% CI: 0.56 - 7.04). One month after hygiene education, there was significant improvement in the key personal hygiene behavior (p < 0.05). The proportion of children having practice of hand washing with soap after defecation significantly improved. Health education on personal hygiene to the school children was effective for behavior change. A multisectoral control approach and hygiene education will help health authorities in strategy of control programs for intestinal parasites among school going children. PMID:22471198

    Tropical dry-deciduous forests comprise more than 45% of the tiger (Panthera tigris) habitat in India. However, in the absence of rigorously derived estimates of ecological densities of tigers in dry forests, critical baseline data for managing tiger populations are lacking. In this study tiger densities were estimated using photographic capture?recapture sampling in the dry forests of Panna Tiger Reserve in Central India. Over a 45-day survey period, 60 camera trap sites were sampled in a well-protected part of the 542-km2 reserve during 2002. A total sampling effort of 914 camera-trap-days yielded photo-captures of 11 individual tigers over 15 sampling occasions that effectively covered a 418-km2 area. The closed capture?recapture model Mh, which incorporates individual heterogeneity in capture probabilities, fitted these photographic capture history data well. The estimated capture probability/sample, 0.04, resulted in an estimated tiger population size and standard error of 29 (9.65), and a density of 6.94 (3.23) tigers/100 km2. The estimated tiger density matched predictions based on prey abundance. Our results suggest that, if managed appropriately, the available dry forest habitat in India has the potential to support a population size of about 9000 wild tigers.

    Organic aerosols are important atmospheric components, and their formation and sources represent important aspects of urban air quality and health effects. Asia, including India, is the largest global source of aerosol particles due to regional natural advection (e.g. desert and soil dust) and anthropogenic activities (e.g. emissions from traffic, industry and burning of coal, biomass and agricultural waste) that generate vast amounts of particulate matter (PM) significantly contributing to climate change. This article reports on the distributions, concentrations, and sources of organic compounds (i.e., alkanes, carboxylic acids, carbonyl compounds, alcohols, plasticizers, PAHs, biomarkers) of PM in the ambient atmosphere of an extensively industrialized area of central India (Raipur, Chhattisgarh, a coal mega-burning region). The dominant components are emissions from fossil fuel utilization, burning of biomass and plastics, and fugitive sources. Speciation and variations of potential new tracer compounds identified are also described.

    Introduction Infectious diseases are one of the major causes of child mortality in India. Pediatric patients are commonly prescribed antibiotics for non-bacterial infections. Monitoring of local antibiotic prescribing with respect to the diagnosis is necessary to improve the prescribing practices. The aim of the study was to describe antibiotic prescribing for potential infections among patients admitted in pediatric departments in two private sector hospitals; one teaching (TH) and one non-teaching (NTH) in Central India. Methods Data from all patients admitted at the pediatric departments of both study hospitals was collected manually, for 3 years (2008–2011) using a customized form. Data from inpatients aged 0–18 years, diagnosed with; acute gastroenteritis (AGE), respiratory tract infections, enteric fever, viral fever or unspecified fever were focused for analysis. Antibiotic prescriptions were analysed using the WHO Anatomical Therapeutic Chemical (ATC) classification system and defined daily doses (DDDs). Adherence to the Indian Academy of Pediatrics list of essential medicines (IAP-LEM) was investigated. P-values <0.05 were considered significant. Results Oftotal6, 825 inpatients admitted at two pediatric departments, 510 patients from the TH and 2,479from the NTH were selected based on the assigned potential infectious diagnoses. Of these, 224 patients (44%) at the TH and 2,088 (84%) at the NTH were prescribed at least one antibiotic during hospital stay (odds ratio-0.69, 95%confidence interval-0.52 to 0.93; p<0.001). Patients with AGE, viral- and enteric fever were frequently prescribed antibiotics at both hospitals, yet higher proportion were prescribed antibiotics at the NTH compared to the TH. Broad-spectrum antibiotics were the most commonly prescribed antibiotic class in both hospitals, namely third generation cephalosporins, J01DD (69%) at the TH, and new fixed dose combinations of antibiotics J01R (FDCs, 42%) at the NTH. At the TH, 37% of the

    In a first of its kind study over the Indian region, concurrent and extensive measurements of black carbon (BC) concentration and atmospheric boundary layer parameters are used to quantify the role of atmospheric boundary layer in producing temporal changes in BC. During this study, 18 months (2011-12) data of continuous measurements of BC aerosols, made over a semi-urban location, Nagpur, in Central India are used along with concurrent measurements of vertical profiles of atmospheric thermodynamics, made using weekly ascents of GPS aided Radiosonde for a period of 1 year. From the balloon data, mixed layer heights and ventilation coefficients are estimated, and the monthly and seasonal changes in BC mass concentration are examined in the light of the boundary layer changes. Seasonally, the BC mass concentration was highest (~ 4573 ± 1293 ng m- 3) in winter (December-February), and lowest (~ 1588 ± 897 ng m- 3) in monsoon (June-September), while remained moderate (~ 3137 ± 1446 ng m- 3) in pre-monsoon (March-May), and post-monsoon (~ 3634 ± 813 ng m- 3) (October-November) seasons. During the dry seasons, when the rainfall is scanty or insignificantly small, the seasonal variations in BC concentrations have a strong inverse relationship with mixed layer height and ventilation coefficient. However, the lowest BC concentrations do not occur during the season when the mixed layer height (MLH) is highest or the ventilation coefficient is the highest; rather it occurs when the rainfall is strong (during summer monsoon season) and airmass changes to primarily of marine origin.

    The evaluation of meteorological and hydrological drought characteristics including the dry spell analysis for planning of supplemental irrigation has been carried out for Bearma basin in Bundelkhand region of Central India. The Bundelkhand region has been under a spell of recurrent droughts. In the last decade, widespread droughts were felt during 2002-2003 and 2007-2008. The drought frequency varies between 1 in 3 years in Rehli and Deori and 1 in 5 years in Hatta. Rehli and Deori blocks falling in Sagar district have been identified to be drought prone. The meteorological drought characteristics evaluated by standardized precipitation index (SPI) indicated that drought severity has increased greatly with the drought intensity varying between -1.22 in Deori and -0.97 in Rehli. The streamflow drought characteristics have been evaluated using streamflow drought index (SDI), whereas the groundwater drought characteristics evaluated by groundwater drought index (GDI). The maximum groundwater drought intensity is observed in Rehli (-0.44). Two critical dry spells (CDS) of 14-18 days invariably occur during the principal rainy months of July and August, for which provision of life-saving supplementary irrigation is essential for the rain-fed agriculture. A drought management plan (DMP) has been developed, based on basin relevant drought indicators and drought triggers, designed and fined tuned to actual drought conditions in the basin. Based on the supply and demand scenario during droughts, an appropriate drought response plan linked to prevailing drought levels has been developed, to effectively manage the scarce water resources during persistent drought scenario. Results of the study are quite promising and the concept of DMP can be replicated to other basins in the region taking into account the basin relevant indicators as necessary.

    Central Himalayan region of India encompasses varied ecological habitats ranging from near tropics to the mid-elevation forests dominated by cool-temperate taxa. In past, we have reported several new records and novel species from Uttarakhand state of India. Here, we assessed genetic variations in three mitochondrial genes, namely, 16S rRNA, cytochrome c oxidase subunit I and cytochrome c oxidase subunit II (COI and COII) in 26 drosophilid species collected along altitudinal transect from 550 to 2700 m above mean sea level. In the present study, overall 543 sequences were generated, 82 for 16S rRNA, 238 for COI, 223 for COII with 21, 47 and 45 mitochondrial haplotypes for 16S rRNA, COI and COII genes, respectively. Almost all species were represented by 2-3 unique mitochondrial haplotypes, depicting a significant impact of environmental heterogeneity along altitudinal gradient on genetic diversity. Also for the first time, molecular data of some rare species like Drosophila mukteshwarensis, Liodrosophila nitida, Lordiphosa parantillaria, Lordiphosa ayarpathaensis, Scaptomyza himalayana, Scaptomyza tistai, Zaprionus grandis and Stegana minuta are provided to public domains through this study.

    Statistical tools for managing the Ambikapur aquifer in central India for sustainable hydrological development of the region Despite India's tremendous progress on all fronts after independence in 1947, the fact remains that it is one of the poorest nation in the world in terms of per capita income and energy consumption which is considered to be the gauge of the economic situation of any country. In case of India, it is nearly one tenth of the developed nations. If economic condition of its people is to be raised, then country has to boost its agriculture production which is largely monsoon dependent and to exploit its conventional and unconventional energy sources at a very rapid growth rate. Although, worldwide, 70% of the water that is withdrawn for human use is used for agriculture, 22% for industry and 8% is used for domestic services. But in India which is a low income country, 82% is used for agriculture, 10% for industry and 8% for domestic services. Therefore, India needs new sources of water to reduce the risk of dependency on the monsoon for the Sustainable Development of the country. It is in this connection that the Ambikapur Basin in the Central India has been studied for sustainable water withdrawal. At present, the crops in the Ambikapur region are totally monsoon dependent. However, with the initiatives of the State Government, 25 boreholes in an area of about 25 square kilometers have been drilled up to a depth of 500m and completed in the Gondwana sandstone. The water quality and the discharge rates have been established to sustain the crops of the area which is the only livelihood of the local people , in case the monsoon fails. The hydraulic properties of the aquifer like Transmissivity (T) and the Coefficient of Storage (S) were determined following the graphic method of Jacob and Theis. The rate of discharge (Q) of the pumped well was estimated at 4.05 x 10 to the power 3 cubic meters per second and the values of other parameters like T at

    To understand the workings of medicine, healing, placebo, belief, and rationality, medical anthropologists need to pay attention to the complex relations of various forms of revelation, contemplation, and rejoining revelation that attach to illness and healing. In this article two performances of a healing technique located in the agricultural plain of Chhattisgarh, central India, are compared: one representing scientific rationality; the other 'blind' superstition. In both performances the practitioner's aim is to reveal: the local healer reveals witchcraft objects from the afflicted body; the local rationalist society reveals the healer's technique as a fraudulent trick. Each performance shares 'an aesthetics of revelation'-they rely on seeing or revealing to obtain their social effect. The interplay between forms of revelation, a reliance on aesthetics for the revelation, and the ways of seeing can indicate how distinctions are made (or not) between doctor and quack, expertise and gimmickry, and truth and falsehood.

    The impact of biomass burning in atmospheric aerosols load is poorly known. We investigated the impact of biomass burning through molecular markers on the concentration of PM2.5 aerosol samples collected from a rural site in eastern central India during three episodic periods from October to November 2011. The collected PM2.5 samples were chemically quantified for potassium as well as sugars and dicarboxylic acids using ion chromatography. Levoglucosan and glucose were found as the most abundant sugar compounds and sugar-alcohols showed the predominance of mannitol whereas oxalic acid was the most abundant diacid followed by maleic acid in PM2.5 aerosols. Substantially enhanced concentrations of K+ as well as levoglucosan and glucose were observed in eastern central India. Analysis of the source specific molecular markers and ratios of sugars and diacids infer that combustion of biomass was the major emission sources of organic compounds associated with PM2.5 aerosols over eastern central India. We applied Spearman correlation analysis and principal component analysis to further investigate the sources of measured sugars and diacids. The concentrations of K+ and levoglucosan were significantly correlated with sugars and diacids that verifying their common sources from biomass burning emission. This study demonstrates that biomass burning for domestic heating and cooking purposes and agricultural activities significantly influence the air quality of eastern central India during the investigation period. The obtained data in this research is helpful for the global scientific community to assessments and remedial of air quality parameters in rural areas of developing countries under similar atmospheric circumstances.

    Malaria is a major public health problem in India and one which contributes significantly to the overall malaria burden in Southeast Asia. The National Vector Borne Disease Control Program of India reported ~1.6 million cases and ~1100 malaria deaths in 2009. Some experts argue that this is a serious underestimation and that the actual number of malaria cases per year is likely between 9 and 50 times greater, with an approximate 13-fold underestimation of malaria-related mortality. The difficulty in making these estimations is further exacerbated by (i) highly variable malaria eco-epidemiological profiles, (ii) the transmission and overlap of multiple Plasmodium species and Anopheles vectors, (iii) increasing antimalarial drug resistance and insecticide resistance, and (iv) the impact of climate change on each of these variables. Simply stated, the burden of malaria in India is complex. Here we describe plans for a Center for the Study of Complex Malaria in India (CSCMi), one of ten International Centers of Excellence in Malaria Research (ICEMRs) located in malarious regions of the world recently funded by the National Institute of Allergy and Infectious Diseases, National Institutes of Health. The CSCMi is a close partnership between Indian and United States scientists, and aims to address major gaps in our understanding of the complexity of malaria in India, including changing patterns of epidemiology, vector biology and control, drug resistance, and parasite genomics. We hope that such a multidisciplinary approach that integrates clinical and field studies with laboratory, molecular, and genomic methods will provide a powerful combination for malaria control and prevention in India.

    Introduction: Dermatophytic infections are commonly encountered a problem and constitute more than 50% of cases in dermatology outpatient departments. Diagnosis of these infections requires the proper use of laboratory methods. Objectives: This study was conducted to know the etiology of dermatophytosis in patients attending Tertiary Care Level Hospital in South India and to compare the efficacy of Sabouraud's dextrose agar (SDA) with actidione and dermatophyte test medium (DTM) in isolating and identifying dermatophytes. Materials and Methods: A total of 110 samples which included 101 skin samples and 9 hair samples from clinically suspected dermatophytosis were collected. Direct microscopy by KOH and culture on SDA with actidione and DTM were done. Results: Of 110 samples collected, 58.18% were KOH positive for fungal filaments and 56.36% were culture positive for dermatophytes. More number of cases were observed between age groups of 21–40 years. Males were more affected compared to females. Tinea corporis was the common clinical presentation observed (40%). Trichophyton rubrum (58.06%) was the predominant isolate recovered in all clinical presentations but Trichophyton violaceum was the most common isolate in tinea capitis. All culture positives were grown on both SDA with actidione and DTM. Appearance of growth was earlier on DTM that is, within 10 days compared to SDA with actidione where growth started appearing only after 10 days. This is statistically significant P < 0.0001 (χ2 = 71.6). Species level identification on primary isolation was possible when grown on SDA with actidione and it was not possible with the growth on DTM on primary isolation. Conclusion: DTM is a good screening medium in laboratory diagnosis of dermatophytosis when compared to SDA with actidione. But DTM is inferior to SDA with actidione in identification of dermatophyte species. PMID:26417157

    Malaria control in Madhya Pradesh is complex because of vast tracts of forest with tribal settlement. Fifty four million individuals of various ethnic origins, accounting for 8% of the total population of India, contributed 30% of total malaria cases, 60% of total falciparum cases and 50% of malaria deaths in the country. Ambitious goals to control tribal malaria by launching "Enhanced Malaria Control Project" (EMCP) by the National Vector Borne Disease Control Programme (NVBDCP), with the World Bank assistance, became effective in September 1997 in eight north Indian states. Under EMCP, the programme used a broader mix of new interventions, i.e. insecticide-treated bed nets, spraying houses with effective residual insecticides, use of larvivorous fishes, rapid diagnostic tests for prompt diagnosis, treatment of the sick with effective radical treatment and increased public awareness and IEC. However, the challenge is to scale up these services.A retrospective analysis of data on malaria morbidity and associated mortality reported under the existing surveillance system of the Madhya Pradesh (Central India) for the years 1996-2007 was carried out to determine the impact of EMCP on malaria morbidity and associated mortality. Analysis revealed that despite the availability of effective intervention tools for the prevention and control of malaria, falciparum malaria remains uncontrolled and deaths due to malaria have increased. Precisely, the aim of this epidemiological analysis is to draw lessons applicable to all international aid efforts, bureaucracy, policy makers and programme managers in assessing its project performance as a new Global Malaria Action Plan is launched with ambitious goal of reducing malaria and its elimination by scaling up the use of existing tools.

    Summer monsoonal rainfall has played an important role in the development and sustenance of the largely agro-based economy in the Indian subcontinent in the recent past. A better understanding of past variations in monsoonal rainfall can therefore lead to an assessment of its potential impact on early human societies. However, our knowledge of spatiotemporal patterns of past monsoon strength, as inferred from proxy records, is limited due to the lack of high-resolution paleo-hydrological records from continental archives. Here, we reconstruct centennial-scale hydrological variability associated with changes in the intensity of the Indian Summer Monsoon based on a record of lipid biomarker abundances and compound-specific stable isotopic composition of a 10-m-long sediment core from saline-alkaline Lonar Lake, situated in the core 'monsoon zone' of south-central India. We identified three periods of distinct hydrology over the Holocene in south-central India. The period between 10.4 and 6.5 ka BP was characterized by a relatively high abundance of land-plant biomarkers, such as long-chain n-alkanes. The composition of these leaf-wax n-alkanes (weighted average of concentration of different chain-length n-alkanes, expressed as the ACL index) and their negative δ13C (-30‰ to -33 ‰) indicate the dominance of woody C3 vegetation in the catchment, and negative δD (-170‰ to -175‰) values argue for a wet period due to an intensified monsoon. Rapid fluctuations in abundance of both terrestrial and aquatic biomarkers between 6.5 and 4 ka BP indicate an unstable lake ecosystem, culminating in a transition to arid conditions. Higher ACL values and a pronounced shift to more positive δ13C values (up to -22‰) of leaf-wax n-alkanes over this period indicate a change of dominant vegetation to C4 grasses. Along with a 40‰ increase in leaf wax n-alkane δD values, which likely resulted from less rainfall and/or higher plant evapotranspiration, we interpret this period

    Background & objectives: Health literacy on tuberculosis (TB) is an understanding about TB to perform activities with regard to prevention, diagnosis and treatment. We undertook a study to assess the health literacy on TB among one of the vulnerable tribal groups (Saharia) in central India. Methods: In this cross-sectional study, 2721 individuals aged >15 yr from two districts of Madhya Pradesh State of India were interviewed at their residence during December 2012-July 2013. By using a short-form questionnaire, health literacy on cause, symptoms, mode of transmission, diagnosis, treatment and prevention of TB was assessed. Results: Of the 2721 (Gwalior 1381; Shivpuri 1340) individuals interviewed; 76 per cent were aged <45 yr. Living condition was very poor (62% living in huts/katcha houses, 84 per cent with single room, 89 per cent no separate kitchen, 97 per cent used wood/crop as a fuel). Overall literacy rate was 19 per cent, and 22 per cent had >7 members in a house. Of the 2721 respondents participated, 52 per cent had never heard of TB; among them 8 per cent mentioned cough as a symptom, 64 per cent mentioned coughing up blood, and 91 per cent knew that TB diagnosis, and treatment facilities were available in both government and private hospitals. Health literacy score among participants who had heard of TB was <40 per cent among 36 per cent of respondents, 41-60 per cent among 54 per cent and >60 per cent among 8 per cent of respondents. Interpretation & conclusions: The finding that nearly half of the respondents had not heard of TB indicated an important gap in education regarding TB in this vulnerable population. There is an urgent need to implement targeted interventions to educate this group for better TB control. PMID:26139783

    The study objective was to determine the role of indigenous medicine practitioners in providing medical care to the people and to identify factors influencing continuity of their practice. 64 registered indigenous medicine practitioners were practicing in a Community Development Block in North India with a total population of 18,000. Only 9 or them were fully institutionally qualified, i.e., they possessed an ayurvedic degree like GAMS or BIMS. Of the remainder, only 10 were partially institutionally qualified, i.e., they had either a diploma or a certificate in ayurvedic or Unani medicine and the remaining 45 were all noninstitutionally qualified (RIMPS). The 45 had no formal training in indigenous medicine, but they all had served apprenticeships to established practitioners in different areas. The duration of apprenticeship had generally been 4-5 years. 44 of them were practicing both allopathic and ayurvedic systems of medicine. The value of the stock of drugs maintained by them ranged from Rs. 500-2500. Except for 3, all were engaged in full time practice. As most of the RIMPs had their clinics on the main roads, they were easily accessible to their clients. Nearly 3/4 of them had nonresidential clinics, and the rest practiced in their own homes. Most of them had only 1 room clinics. Furnishings usually included a wooden table and chair and a couple of benches for waiting clients. The following were among the study findings: cosmopolitan medicine was still favored by a majority of the rural people; the traditional healers were approached more for the treatment of chronic nonincapacitating dysfunctions rather than critical incapacitating dysfunctions; some traditional healers made claims of curing barrenness, impotency, veneral disease, and certain chronic diseases; the traditional healers moved from 1 place to another in the course of their training and practice; most of them stayed in touch with doctors practicing in towns to acquire knowledge of new remedies

    In the last couple of decades constructed wetlands (CWs) have drawn considerable interest in Central India. CWs offer an effective means of integrating wastewater treatment and resource enhancement, often at competitive cost in comparison to conventional wastewater treatments, with additional benefits of Green Urban Landscaping and wildlife habitat. This paper describes treatment performances and the design of some Sub Surface Flow CWs (SSFCW) and Artificial Floating Islands (AFIs) in Central India. Central Indian CWs show significant pollution reduction load for total suspended solids (TSS) (62-82%), biochemical oxygen demand (BOD) (40-75%), NH(4)-N (67-78%) and total Kjeldahl nitrogen (TKN) (59-78%). Field scale SSFCWs installed so far in Central India are rectangular, earthen, single/multiple celled having similar depths of 0.60-0.90 m, hydraulic retention capacity 18-221 m(3) with effective size 41.8-1,050 m(2). The major components of CWs incorporate puddled bottom/side walls, sealed with impermeable low-density polyethylene, a bed of locally available river gravel planted with Phragmites karka, and an inlet distribution and outlet collection system. A new variant on CWs are AFIs working under hydroponics. The field scale experimental AFIs installed in-situ in a slowly flowing local river were composed of hollow bamboo, a bed of coconut coir, floating arrangements and Phragmites karka as nutrient stripping plant species. The AFIs polish the aquatic system by reducing 46.6% of TSS, 45-55% of NH(4)-N, 33-45% of NO(3)-N, 45-50% of TKN and 40-50% of BOD. The study established that there is a need for further research and sufficient data to assist the development of CWs by instilling confidence in policymakers, planners and in the public.

    Long-term (8 years), simultaneous data on aerosol optical properties from MODIS and OMI satellite sensors are analyzed to study their temporal characteristics and to infer on the major aerosol types present over the study location, Bangalore situated in south central peninsular India. Investigations are carried out on Aerosol Optical Depths (AODs), Angstrom exponent (α) and Aerosol Index (AI) for the purpose. Aerosol parameters exhibited significant seasonal variations: AODs peaking during monsoon, α during post-monsoon and AI during summer. Seasonal air mass back trajectories are computed to infer on the transport component over the study region. By assigning proper thresholds (depending on the nature of the location and transport pathways) on AOD and α values, aerosols are discriminated into their major types viz., marine influenced, desert dust, urban/industrialized and mixed types. Further sub-categorization of the aerosols has been done on an annual scale taking into account of their absorptance information in terms of the OMI-AI values. Mixed type aerosols contributed the most during all the seasons. Next to mixed type aerosols, marine influenced aerosols dominated during winter, desert dust during monsoon and summer, urban/industrialized aerosols during post-monsoon. Considering the urban nature of the study location, urban/industrialized/carbonaceous type aerosols have been significantly underestimated in these methodologies. Finally, discussion has been made on the consistency of the results obtained from the methodologies (i) based on AODs and α; (ii) based on AODs, α and AI. PMID:24095970

    Data from early in the twentieth century up to the present day indicate that Rattus rattus among rodents and Xenopsylla cheopis among fleas are the two most important elements in urban human plague infection in India, R. norvegicus playing a more minor role. The relative numbers of both these species have decreased in recent years in Bombay and Calcutta, while those of Bandicota bengalensis, which is less heavily parasitized by X. cheopis, have risen. This reduction in the numbers of the epidemiologically more important rodents and their fleas has been accompanied by a reduction in the number of human plague cases. PMID:20604076

    Investigations on surface sediments and a sediment core from Lake Lonar in central India were carried out within the framework of the HIMPAC (Himalaya: Modern and Past Climate) programme. The aim was to understand recent productivity, sedimentation, and degradation processes and to reconstruct variations in Holocene lake conditions on the basis of biogeochemical analysis on a 10 m long sediment core retrieved from the centre of Lake Lonar. Located in India's core monsoon zone, Lake Lonar offers valuable information about the climate development of the whole region. The lake is situated at the floor of a meteorite impact structure on the Deccan plateau basalt. The modern lake is characterised by brackish water, high alkalinity, severe eutrophication, and bottom water anoxia. The lake is about 6 m deep and fed by rainfall during the SW monsoon season and three perennial streams. Since no out-flowing stream is present and no seepage loss occurs, the lake level is highly sensitive to the balance of precipitation and evaporation. Here we present C/N, carbon and nitrogen isotope, and amino acid data of bulk organic matter from modern lake and Holocene core sediments. Modern conditions are mainly related to human activity which started to have persistent influence on the biological and chemical lake properties at ~1200 cal a BP. The distribution of δ13C in the modern sediments is driven by the ratio between terrestrial and aquatic organic matter, while δ15N seems to be influenced by redox conditions at the sediment-water-interface with elevated values at shallow oxic stations. Differences in the amino acid assemblages of oxic and anoxic surface sediment samples were used to calculate an Ox/Anox ratio indicating the redox conditions during organic matter degradation. The onset of the monsoon reconstructed from the sediment core occurred at ca. 11450 cal a BP. The early Holocene core sediments are characterised by low sedimentation rate, low aquatic productivity, and

  14. Nuclear fuel cycle assessment of India: A technical study for U.S.-India cooperation

    NASA Astrophysics Data System (ADS)

    Krishna, Taraknath Woddi Venkat

    The recent civil nuclear cooperation proposed by the Bush Administration and the Government of India has heightened the necessity of assessing India's nuclear fuel cycle inclusive of nuclear materials and facilities. This agreement proposes to change the long-standing U.S. policy of preventing the spread of nuclear weapons by denying nuclear technology transfer to non-NPT signatory states. The nuclear tests in 1998 have convinced the world community that India would never relinquish its nuclear arsenal. This has driven the desire to engage India through civilian nuclear cooperation. The cornerstone of any civilian nuclear technological support necessitates the separation of military and civilian facilities. A complete nuclear fuel cycle assessment of India emphasizes the entwinment of the military and civilian facilities and would aid in moving forward with the separation plan. To estimate the existing uranium reserves in India, a complete historical assessment of ore production, conversion, and processing capabilities was performed using open source information and compared to independent reports. Nuclear energy and plutonium production (reactor- and weapons-grade) was simulated using declared capacity factors and modern simulation tools. The three-stage nuclear power program entities and all the components of civilian and military significance were assembled into a flowsheet to allow for a macroscopic vision of the Indian fuel cycle. A detailed view of the nuclear fuel cycle opens avenues for technological collaboration. The fuel cycle that grows from this study exploits domestic thorium reserves with advanced international technology and optimized for the existing system. To utilize any appreciable fraction of the world's supply of thorium, nuclear breeding is necessary. The two known possibilities for production of more fissionable material in the reactor than is consumed as fuel are fast breeders or thermal breeders. This dissertation analyzes a thermal

    2014-02-01

    The aim of the present research was to investigate the seasonal impact on nearshore beach dynamics and the status of heavy mineral distribution along central Tamil Nadu coast, India. Beach profile measurements were made in 10 profiling sites between Thirukadaiyur and Velankanni on monthly and seasonal basis from January 2011 to July 2012. Using beach profile data, variation in beach width, slope and volumetric changes have been calculated. Beach slope and nearshore wave parameters were used to quantify the longshore sediment transport rate. Beaches between Thirukadaiyur and Karaikkal attained predominant transport rate in northern direction whereas, the rest of the beaches are in southern direction. The seasonal action of wind and wave currents create nearshore bar during northeast (NE) monsoon and frequent berms at tidal zone during southwest (SW) monsoon. Surface sediment samples were collected in each location for quantifying the heavy mineral weight percentage during the period of pre- and post-Thane cyclone. Sediments were also studied by X-ray diffraction (XRD) to evaluate the changes and occurrence of heavy minerals in beach sands. The XRD results show that sediments in the study area have enriched heavy mineral distribution even after strong cyclonic event. It confirms the redistribution of heavy mineral deposits present in the coast. The results suggested that monsoonal action has influenced the seasonal changes in beach morphology and it does not affect the heavy mineral distribution.

    Tawa River is the biggest left bank tributary of the Narmada, the largest west-flowing river of the Indian peninsula. Central India enjoys a tropical climate, is highly urbanized, and the river flow is mostly controlled by monsoon; a large part of the population depend on rivers for their livelihood. Spatial and temporal variations in the hydrochemistry of the Tawa River were studied based on seasonal sampling along the course of the river and its tributaries. The study is important because not much data exist on small size rivers and the river processes spell out correctly in smaller basins. The monsoon season accounts for more than 70% of river water flow. The basin is characterized by silicate lithology; however, water chemistry is controlled by carbonate-rich soils and other weathering products of the silicate rocks, as indicated by the high (Ca + Mg)/(Na + K) ratios (>3.8). The values of the Na-normalized ratios of Ca(2+), Mg(2+), and HCO₃(-) suggest that both the carbonate and silicate lithology contribute to the hydrochemistry. On average, 42% of HCO₃(-) in the Tawa River water is contributed by silicate weathering and 58% from carbonate lithology. The water remains undersaturated with respect to calcite during the monsoon and post-monsoon seasons and supersaturated during the pre-monsoon season. A significant influence of mining in the basin and other industrial units is observed in water chemical composition. PMID:23761165

    2015-01-01

    Background Skilled birth attendance and institutional delivery have been advocated for reducing maternal, perinatal and neonatal mortality (PMR and NMR). India has successfully implemented various strategies to promote skilled attendance and incentivize institutional deliveries in the last 5 years. Objectives The study evaluates the trends in institutional delivery, PMR, NMR, and their risk factors in two Eunice Kennedy Shriver NICHD Global Network for Women’s and Children’s Health Research sites, in Belgaum and Nagpur, India, between January 2010 and December 2013. Design/methods Descriptive data stratified by level of delivery care and key risk factors were analyzed for 36 geographic clusters providing 48 months of data from a prospective, population-based surveillance system that registers all pregnant permanent residents in the study area, and their pregnancy outcomes irrespective of where they deliver. Log binomial models with generalized estimating equations to control for correlation of clustered observations were used to test the trends significance Results 64,803 deliveries were recorded in Belgaum and 39,081 in Nagpur. Institutional deliveries increased from 92.6% to 96.1% in Belgaum and from 89.5% to 98.6% in Nagpur (both p<0.0001); hospital rates increased from 63.4% to 71.0% (p=0.002) and from 63.1% to 72.0% (p<0.0001), respectively. PMR declined from 41.3 to 34.6 (p=0.008) deaths per 1,000 births in Belgaum and from 47.4 to 40.8 (p=0.09) in Nagpur. Stillbirths also declined, from 22.5 to 16.3 per 1,000 births in Belgaum and from 29.3 to 21.1 in Nagpur (both p=0.002). NMR remained unchanged. Conclusions Significant increases in institutional deliveries, particularly in hospitals, were accompanied by reductions in stillbirths and PMR, but not by NMR. PMID:26063586

    Background: Conventional microscopy underestimates the burden of malarial infection when compared with molecular diagnosis using polymerase chain reaction (PCR)-based methods. Lower density parasitemias serve as a reservoir for infection. We evaluated the prevalence of submicroscopic infections in an area of unstable malarial transmission in India and determined whether these infections negatively impacted maternal or fetal outcomes. Methods: This cross-sectional study (2007–2008) was undertaken in two districts of Chhattisgarh, recruiting women from both antenatal clinics (ANCs) and delivery units (DUs). For ANC/DU subjects, peripheral/placental blood, respectively, was obtained for conventional microscopy and collected onto filter paper for PCR analysis. Results: There were 3425 pregnant women, including 2477 ANC subjects and 948 DU subjects who had both microscopic and PCR samples available. Polymerase chain reaction detected significantly more Plasmodium infections than traditional light microscopy both from peripheral (3.4 vs 1.2%; OR 2.9, 95% confidence intervals (CIs) 1.9–4.5) and placental (4.2 vs 1.7%; OR 2.5, 95% CIs 1.4–4.8) blood samples. Submicroscopic infections were not associated with anemia or severe maternal anemia among ANC or DU participants and were not associated with low birth weight (LBW) among DU participants. In contrast, microscopically detected infections were associated with severe anemia and LBW. Conclusions: In this area of unstable malarial transmission from India, submicroscopic infections did not identify a set of pregnant women at increased risk for anemia or LBW. Until PCR techniques become much less expensive and available as a point of care test for the field setting, its use will be limited for malarial detection. PMID:25627878

    Arsenic contamination in the environment (i.e. surface, well and tube-well water, soil, sediment and rice samples) of central India (i.e. Ambagarh Chauki, Chhattisgarh) is reported. The concentration of the total arsenic in the samples i.e. water (n = 64), soil (n = 30), sediment (n = 27) and rice grain (n = 10) were ranged from 15 to 825 microg L(-1), 9 to 390 mg kg(-1), 19 to 489 mg kg(-1) and 0.018 to 0.446 mg kg(-1), respectively. In all type of waters, the arsenic levels exceeded the permissible limit, 10 microg L(-1). The most toxic and mobile inorganic species i.e. As(III) and As(V) are predominantly present in water of this region. The soils have relatively higher contents of arsenic and other elements i.e. Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Ga, Zr, Sn, Sb, Pb and U. The mean arsenic contents in soil of this region are much higher than in arsenic soil of West Bengal and Bangladesh. The lowest level of arsenic in the soil of this region is 3.7 mg kg(-1) with median value of 9.5 mg kg(-1). The arsenic contents in the sediments are at least 2-folds higher than in the soil. The sources of arsenic contamination in the soil of this region are expected from the rock weathering as well as the atmospheric deposition. The environmental samples i.e. water, soil dust, food, etc. are expected the major exposure for the arsenic contamination. The most of people living in this region are suffering with arsenic borne diseases (i.e. melanosis, keratosis, skin cancer, etc.). PMID:16003581

    Background Dental health care providers may be exposed to a variety of microorganisms via blood, oral or respiratory secretions. Though the risk of transmission of Human Immunodeficiency Virus (HIV) in dental settings is low, the consequences of being infected are life threatening. Therefore, high standards in infection control and waste management are required in controlling occupational contagion and cross infection. Aim To obtain comprehensive information about the HIV related information, its impact on the health care provider’s attitude towards treating patients living with HIV/AIDS (PLWHA), infection control & waste disposal practices among dental professionals of Malwa region of Madhya Pradesh; situated in Central India. Materials and Methods A cross-sectional survey was conducted among 320 private dental practitioners. Data was collected using a pretested, self administered 40 item questionnaire and statistically analysed. Results The response rate was 81.25%. Over all 50.76% dentists were graded as having good knowledge of HIV. Unfortunately, their willingness to treat these patients remained low. In all 39.23% dentist were willing to render care to PLWHA. Junior dentists expressed less hesitation with regard to acceptance of risk patients than other dentists. Over 65% of the respondents reported adherence to universal precautions. The most alarming observation was that dentists were not following safe waste management practices. Conclusion Dental professionals continue to indicate a reluctance to treat patients with HIV/AIDS or those in high- risk groups. The results suggest need to have a comprehensive motivational program and implementing ways to ensure access and availability of safe dental care for PLWHA. The desire to get training on how to handle PLWHA illustrates that receptiveness to change exists. PMID:26393211

    The paper reports the measurements of biophysical parameters using field and satellite data over a tropical deciduous forest Kanha National Park (KNP), central India. Field measurement (GBH, LAI, litter, soil moisture) was carried out over ten quadrates of 0.1ha in KNP for characterization of biophysical parameters with specified measurement protocol and sampling. Satellite based remote sensing analysis (LAI, Phenology, and NPP) was carried out using multi date observations of IRS-LISS-III, IMS-1MX, SPOT-VEGETATION and EOS-MODIS instruments. Rank correlation analysis using field data collected in the selected quadrates at KNP showed Sal (Shorea robusta) is dominant forest species followed by Lendia, Jamun (Syzygium cumini), Saja, Harra and Dhawda etc. Field measurement of Sal showed GBH range from 20 cm to 170 cm. Different forest classes such as Sal; Sal mixed with Jamun, Bamboo (Dendrocalamus strictus) etc, including grasslands/scrubland were classified with overall accuracy of 85.56 percent using March, May and October multi spectral data. Sal has distinct growth characteristics (low vegetation growth/ leaf fall in March instead of May) as compared to other vegetation species. As per the Leaf Area Index (LAI) measurement using hemispherical photographs, Sal showed the highest LAI (6.95 m2/m2) during September and lowest LAI (2.63 m2/m2) during March. Overall good agreement (r= 0.79) was found between the LAI generated from LISS-III and MODIS data product. It was observed from SPOT-VEGETATION analysis that NPP varied from 8.4 tC/ha/year (dry deciduous forest) to 14.25 tC/ha/year (Moist deciduous forest) in KNP.

    On the basis of relative abundance, frequency and biovolume, the important value index ranks were assigned to individual cyanobacteria in phytoplankton samples collected from fourteen water resources of Central India. The mcyABDE genes were detected in all the blooms with Microcystis (-aeruginosa, -viridis, -panniformis, -botrys) as being the major constituent morphospecies. On the other hand, blooms composed of primarily Oscillatoria (-limosa,-agardhii, -laetevirens) along with Anabaena, Nostoc, Phormidium and Spirulina as sub-dominant forms exhibited quite a patchy distribution of one or the other mcy genes. Fifty percent of Microcystis- but none of the Oscillatoria dominant blooms produced microcystins-RR and desmethyl-RR at 0.03-0.41mgg(-1) bloom dry mass. Traces of dissolved microcystin was detected in lake water, which is well below the WHO guideline. Irrespective of cyanobacterial composition and microcystin production ability, during the study period 43-64% of the cyanobacterial bloom samples exhibited association of viable but nonculturable forms of Vibrio cholerae O1 and O139, as evident from amplification of the antigen genes. We believe that spread of endemic cholera is the major threat associated with harmful algal blooms. PMID:25682583

    A unique feature observed in the tropical and subtropical coastal area is the diurnal sea-breeze/land-breeze cycle. We examined the nearshore waves at 5 and 15 m water depth during the active sea/land breeze period (January-April) in the year 2015 based on the data measured using the waverider buoys moored in the eastern Arabian sea off Vengurla, central west coast of India. Temporal variability of diurnal wave response is examined. Numerical model Delft3D is used to study the nearshore wave transformation. The wave height increased due to the sea breeze and reached its peak at ˜ 13:00 UTC at 15 m water depth, whereas the peak significant wave height is at 12:00 UTC at 5 m water depth. Due to the influence of the land/sea breeze system, the range of the peak wave period in 1 day varied up to 8 s. Reduction in the wave height of wind-sea is around 20 % and that of the swell is around 10 % from 15 to 5 m water depth.

    The central Bundelkhand greenstone complex in Bundelkhand craton, northern India is one of the well exposed Archaean supracrustal amphibolite, banded iron formation (BIF) and felsic volcanic rocks (FV) and associated with grey and pink porphyritic granite, tonalite-trondhjemite-granodiorite (TTG). Here we present high precision zircon U-Pb geochronological data for the pinkish porphyritic granites and TTG. The zircons from the grey-pinkish porphyritic granite show three different concordia ages of 2531 ± 21 Ma, 2516 ± 38 Ma, and 2514 ± 13 Ma, which are interpreted as the best estimate of the magmatic crystallization age for the studied granites. We also report the concordia age of 2669 ± 7.4 Ma for a trondhjemite gneiss sample, which is so far the youngest U-Pb geochronological data for a TTG rock suite in the Bundelkhand craton. This TTG formation at 2669 Ma is also more similar to Precambrian basement TTG gneisses of the Aravalli Craton of north western India and suggests that crust formation in the Bundelkhand Craton occurred in a similar time-frame to that recorded from the Aravalli craton of the North-western India.

    Background: A previous hospital based study from Delhi revealed a high prevalence of hypothyroidism in pregnant women. Several other studies with small sample size also indicate a rising trend of prevalence of hypothyroidism during pregnancy in India. Objective: To assess prevalence of hypothyroidism in pregnant women from various states/cities across India. Materials and Methods: This was a cross-sectional multicenter study conducted at Allahabad (Uttar Pradesh), Bengaluru (Karnataka), Chennai (Tamil Nadu), Kolkata (West Bengal), Hyderabad (Telangana), Nasik (Maharashtra), Rohtak (Haryana), Pune (Maharashtra), New Delhi (Delhi), Srinagar (Kashmir), and Vizag (Andhra Pradesh) enrolling 2599 pregnant women. Estimation of thyroid stimulating hormone (TSH), free T4, and antithyroid peroxidase (TPO) antibodies was carried out using Roche modular kit using ECLIA technology in a central laboratory. Results: We found in our study population that 13.13% of pregnant women have hypothyroidism (n = 388), using a cutoff TSH level of 4.5 μIU/ml. This prevalence was much higher using the American Thyroid Association criteria. Anti-TPO antibodies were positive in 20.74% of all pregnant women (n = 613), whereas 40% (n = 155) of hypothyroid pregnant women were positive for anti-TPO antibodies. Conclusion: This study concludes that there is a high prevalence of hypothyroidism (13.13%), majority being subclinical in pregnant women during the first trimester from India and universal screening of hypothyroidism may be desirable in our country.

    Fluoride concentration in groundwater sources used as major drinking water source in rural area of block Nawa (Nagaur District), Rajasthan was examined and the toxic effects by intake of excess fluoride on rural habitants were studied. In block 13, habitations (30%) were found to have fluoride concentration more than 1.5 mg/l (viz. maximum desirable limit of Indian drinking water standards IS 10500, 1999). In five habitations (11%), fluoride concentration in groundwater is at toxic level (viz. above 3.0 mg/l). The maximum fluoride concentration in the block is 5.91 mg/l from Sirsi village. As per the desirable and maximum permissible limit for fluoride in drinking water, determined by World Health Organization or by Bureau of Indian Standards, the groundwater of about 13 habitations of the studied sites is unfit for drinking purposes. Due to the higher fluoride level in drinking water, several cases of dental and skeletal fluorosis have appeared at alarming rate in this region. There is an instant need to take ameliorative steps in this region to prevent the population from fluorosis. Groundwater sources of block Nawa can be used for drinking after an effective treatment in absence of other safe source. The evaluation of various defluoridation methods on the basis of social and economical structure of India reveals that the clay pot chip, activated alumina adsorption, and Nalgonda techniques are the most promising.

    The DFG funded HIMPAC (Himalaya: Modern and Past Climates) programme aims to reconstruct Holocene Indian Monsoon climate using a multi-proxy and multi-archive approach. First investigations made on sediments from a ca. 10 m long core covering the whole Holocene taken from the lake Lonar in central India's state Maharashtra, Buldhana District, serve to identify changes in sedimentation, lake chemistry, local vegetation and regional to supra-regional climate patterns. Lake Lonar occupies the floor of an impact crater that formed on the ~ 65 Ma old basalt flows of the Deccan Traps. It covers an area of ca. 1 km2 and is situated in India's core monsoon area. The modern lake has a maximum depth of about 5 m, is highly alkaline, and hyposaline, grouped in the Na-Cl-CO3 subtype of saline lakes. No out-flowing stream is present and only three small streams feed the lake, resulting in a lake level highly sensitive to precipitation and evaporation. The lake is eutrophic and stratified throughout most of the year with sub- to anoxic waters below 2 m depth. In this study the core sediments were analysed for their total amino acid (AA) and amino sugar (AS) content, the amino acid bound C and N percentage of organic C and total N in the sediment and the distribution of individual amino acids. The results roughly show three zones within the core separated by distinct changes in their AA content and distribution. (i) The bottom part of the core from ca. 12000 cal a BP to 11400 cal a BP with very low AA and AS percentage indicating high lithogenic contribution, most probably related to dry conditions. (ii) From 11400 cal a BP to 1200 cal a BP the sediments show moderate AA and AS percentages and low values for the ratios of proteinogenic AAs to their non-proteinogenic degradation products (e.g. ASP/β-ALA; GLU/γ-ABA). (iii) The top part of the core (< 1200 cal a BP) is characterised by an intense increase in total AA and AS, AA-C/Corg and AA-N/Ntotas well as in the ratio of

    Coastal and estuarine environments, world over are facing immense impact due to both natural and anthropogenic processes. The natural processes include climatic changes, rise in sea level, cyclone, flood, tsunamis, coastal erosion, salinity ingress and siltation. Likewise, anthropogenic pressures include population expansion, ocean traffic, dredging, resource exploitation, pollution, unplanned urbanization and intensive industrialization. Due to these impacts the fragile coastal ecosystem and its entities, like sub ecosystems, resources, morphological units are undergoing unprecedented degradation, rendering these coastal regions vulnerable, impinging risk to human population, livestock, properties, as also, devastation of resourceful lands. This accelerates economic fatalities and irreversible obliteration to the ecosystems. Evidences on the global concern towards this issue have been well established. The countries world over, including India, pledged consensus towards the protection of the fragile coastal ecosystems through UNCED, Agenda-21. India, on 19th February 1991, has designated specified corridors along the landward side of the coastline as "Coastal Regulatory Zones" (CRZ), through appropriate policy and law. In context with the CRZ notification, scientific database at local and site-specific areas, developed. Synergy of ecosystems, landscape and resources with demographic, tourism data, vis-à-vis, economic corridors/sectors aided the paradigms and criterion for local and site specific prescriptions for Goa Coast. The Goa coast is a part of central west coast of India and is characterized by pocket beaches flanked by rocky cliffs, estuaries, bays, and at some places mangroves. Beaches in southern Goa are long and linear in nature with sand dunes. The Mandovi and Zuari estuarine system in Goa is the largest in this part of the coast. Mud flats, swampy marshes and wetlands are found mainly along estuaries and creeks. The beaches of Goa are stable beaches

    Pharmacovigilance is useful in assuring the safety of medicines and protecting the consumers from their harmful effects. A number of single drugs as well as fixed dose combinations have been banned from manufacturing, marketing and distribution in India. An important issue about the availability of banned drugs over the counter in India is that sufficient adverse drug reactions data about these drugs have not been reported. The most common categories of drugs withdrawn in the last decade were nonsteroidal antiinflammatory drugs (28%), antidiabetics (14.28%), antiobesity (14.28%), antihistamines (14.28%), gastroprokinetic drugs (7.14%), breast cancer and infertility drugs (7.14%), irritable bowel syndrome and constipation drugs (7.14%) and antibiotics (7.14%). Drug withdrawals from market were made mainly due to safety issues involving cardiovascular events (57.14%) and liver damage (14.28%). Majority of drugs have been banned since 3-5 years in other countries but are still available for sale in India. The present study compares the drug safety monitoring systems in the developed countries such as the USA and UK and provides implications for developing a system that can ensure the safety and efficacy of drugs in India. Absence of a gold standard for a drug safety surveillance system, variations in culture and clinical practice across countries makes it difficult for India to completely adopt another country's practices. There should be a multidisciplinary approach towards drug safety that should be implemented throughout the entire duration spanning from drug discovery to usage by consumers. PMID:25425751

    The current understanding of the Himalayan lithosphere stems mostly from cross-sections through the range at the longitude of the Kathmandu Basin. In this paper we laterally extend the analyses of structures and rheology along the Nepal Himalayas between the Pokhara valley and the Arun river. We take advantage of available information and a new data set including gravity measurements and a receiver function profile. It appears that the geometry of the Moho inferred from seismological profiles and long-wavelength gravity anomalies does not exhibit major East-West variations within the 350-km-wide study area. Using thermomechanical modelling, we show that the northward deepening of the Moho observed along profiles perpendicular to the main thrust faults can be interpreted simply as the bending of a strong India Plate. This result suggests a gradual mechanical decoupling between the crust and the mantle, leading to a northward decrease of the effective elastic thickness of the Indian lithosphere from ˜75 km to ˜25 km beneath the Ganga Basin and the Tibetan Plateau, respectively. Our results also confirm (partially) eclogitized lower Indian crust beneath southern Tibet. At shorter wavelengths, the observed gravity profiles exhibit some small lateral variations that can be interpreted in terms of east-west variations of the thickness of subsurface geological structures such as the Ganga Basin and the Tethyan Sedimentary Sequence.

    The object of this study was to compare components of quality of care provided to female outpatients by practitioners working in the private and public sectors in Karnataka State, India. Consultations conducted by 18 private practitioners and 25 public-sector practitioners were observed for 5 days using a structured protocol. Private practitioners were selected from members of the Indian Medical Association in a predominantly rural sub-district of Kolar District. Government doctors were selected from a random sample of hospitals and health centres in three sub-districts of Mysore District. A total of 451 private-sector and 650 public-sector consultations were observed; in each sector about half involved a female practitioner. The mean length of consultation was 2.81 minutes in the public sector and 6.68 minutes in the private sector. Compared with public-sector practitioners, private practitioners were significantly more likely to undertake a physical examination and to explain their diagnosis and prognosis to the patient. Privacy was much better in the private sector. One-third of public-sector patients received an injection compared with two-thirds of private patients. The mean cost of drugs dispensed or prescribed were Rupees 37 and 74 in public and private sectors, respectively. Both in terms of thoroughness of diagnosis and doctor-patient communication, the quality of care appears to be much higher in the private than in the public sector. However, over-prescription of drugs by private practitioners may be occurring. PMID:15459165

    A field-scale 4-celled, horizontal subsurface constructed wetland (CW) was installed to evaluate removal efficiencies of wastewater constituents in an industrial distillery effluent. Total and dissolved solids, NH4-N, TKN, P and COD were measured. This CW design provides four serial cells with synthetic liners and a river gravel base. The first two unplanted cells provide preliminary treatment. Specific gravel depths and ensuing biofilm growth provides anaerobic treatment in Cell 1 and anaerobic treatment in Cell 2. Cell 3 was planted with Typha latifolia with an inserted layer of brick rubble (for phosphorus removal). Locally grown reed, Phragmites karka was planted in Cell 4. COD was reduced from 8420 mg/l 3000 from Cell 1 to the outlet of Cell 4. Likewise other parameters: total and dissolved solids, ammonium and total nitrogen, and total P, indicated declining trends at the 4-celled CW effluent. This study reveals how high strength distillery wastewater strongly impacts morphology, aeration anatomy in the chiseled plant tissues, reed growth; and composition of the biofilm in the specialized substratum. The reliability of a CW for organic and nutrients reduction, in association with a poorly performing conventional system is discussed. There is an immense potential for appropriately designed constructed wetlands to improve high strength wastewaters in India. PMID:11804132

    Background & objectives: Malaria is a major public health problem in many States of the country, particularly, in Madhya Pradesh where both Plasmodium vivax and P. falciparum are endemic. Although many studies have been conducted to investigate risk factors for malaria, but only a few have examined household and socio-economic risk factors. The present study was, therefore, undertaken to explore the relationship of different socio-demographic, socio-economic and behavioural risk factors with malaria prevalence in tribal areas of Madhya Pradesh, India. Methods: This study was undertaken in all 62 villages of Bargi Primary Health Centre from May 2005 to June 2008. These villages comprised 7117 households with an average family size of five members. Fortnightly fever surveys were conducted in all villages to assess prevalence of malaria infection in the community. The distinct univariate and multivariate logistic regression models were fitted on the data set. Results: The important socio-demographic risk factors like age of household head, social group, occupation and family size; socio-economic factors like type of walls of house, place of drinking water source, irrigated land, cash crop; and behavioural variables like place of sleeping, use of bed nets, etc. were found significantly associated with malaria in univariate analyses. In multivariate analyses only social groups, family size, type of walls of house, and place of sleeping had strong significant association with prevalence of malaria. Interpretation & conclusions: The study shows that in tribal areas where people are living in poor quality of houses with no proper use of preventive measures, malaria is firmly established. We conclude that community based interventions which bring improvement in standard of living, access to healthcare facilities and health awareness, will have a significant impact on malaria prevention in these areas.

    Chronic kidney disease (CKD) has attained epidemic proportions in India due to increased incidence of diabetes and hypertension (HTN). It was surmised that identification of only high-risk groups (HRGs) through a questionnaire would be sufficient to identify cases of kidney damage (KD). The study attempted to device a questionnaire to classify the subjects in to HRG and low-risk group (LRG) and assess the extent of early KD. The central government employees were classified into HRG and LRG based on "SCreening for Occult REnal Disease (SCORED)" and "EXTENDED" questionnaire formulated after addition of 10 more parameters apart from diabetes and HTN. Urine examination by dipstick, quantitative microalbumin, serum creatinine, and estimated glomerular filtration rate were assessed to determine KD. The data were analyzed for risk-group classification. Sensitivity was calculated based on the number of KD cases in the HRG. Of the 1104 employees screened, 58% and 42% were classified in HRG and LRG, respectively. There were 306 KD cases of whom, 65% were in the HRG. The sensitivity of the EXTENDED questionnaire to detect CKD was much higher (60%) compared to the SCORED questionnaire (25%). The prevalence of KD according to stage was: stage-1, 13.4%; stage-2, 9.9%; and late stages (3, 4, and 5), 4.5%. Microalbuminuria and dipstick-positive proteinuria showed statistically higher proportion in the HRG (25% and 4.1%) than in the LRG (19% and 1%, respectively) (P <0.05). Although the EXTENDED questionnaire was more sensitive in detecting KD, only screening the high-risk population will leave behind 35% of KD cases. There is, therefore, a need for mass screening at regular intervals. PMID:26997392

    Objective Smoke from burning of biomass fuels has been linked with adverse pregnancy outcomes and with hypertension among nonpregnant subjects; association with hypertension during pregnancy has not been well studied. We sought to evaluate whether use of wood cooking fuel increases the risk of maternal hypertension at delivery compared to gas which burns with less smoke. Methods Information on fuel use and blood pressure was available for analysis from a cross-sectional survey of 1369 pregnant women recruited at delivery in India. Results Compared to gas users, women using wood as fuel had on average lower mean arterial pressure (adjusted effect size −2.0 mmHg; 95% CI −3.77, −0.31) and diastolic blood pressure (adjusted effect size −1.96 mmHg; 95% CI −3.60, −0.30) at delivery. Risk of hypertension (systolic > 139 mmHg or diastolic > 89 mmHg) was 14.6% for women cooking with wood compared to 19.6% for those cooking with gas although this did not reach significance after adjustment, using propensity score techniques, for factors that make wood and gas users distinct (adjusted prevalence ratio 0.76; 95% CI 0.49, 1.17). Conclusions Combustion products from the burning of biomass fuels are similar to those released with tobacco smoking which has been linked with a reduced risk for preeclampsia. The direction of our findings suggests the possibility of a similar effect for biomass cook smoke. Whether clean cook cooking interventions being promoted by international advocacy organizations will impact hypertension in pregnancy warrants further analysis as hypertension remains a leading cause of maternal death worldwide and cooking with biomass fuels is widespread.

    Background Despite the avoidable nature of maternal mortality, unacceptably high numbers of maternal deaths occur in developing countries. Considering its preventability, maternal mortality is being increasingly recognised as a human rights issue. Integration of a human rights perspective in maternal health programmes could contribute positively in eliminating avertable maternal deaths. This study was conducted to explore socio-cultural and service delivery–related dimensions of maternal deaths in rural central India using a human rights lens. Design Social autopsies were conducted for 22 maternal deaths during 2011 in Khargone district in central India. The data were analysed using thematic analysis. The factors associated with maternal deaths were classified by using the ‘three delays’ framework and were examined by using a human rights lens. Results All 22 women tried to access medical assistance, but various factors delayed their access to appropriate care. The underestimation of the severity of complications by family members, gender inequity, and perceptions of low-quality delivery services delayed decisions to seek care. Transportation problems and care seeking at multiple facilities delayed reaching appropriate health facilities. Negligence by health staff and unavailability of blood and emergency obstetric care services delayed receiving adequate care after reaching a health facility. Conclusions The study highlighted various socio-cultural and service delivery–related factors which are violating women's human rights and resulting in maternal deaths in rural central India. This study highlights that, despite the health system's conscious effort to improve maternal health, normative elements of a human rights approach to maternal health (i.e. availability, accessibility, acceptability, and quality of maternal health services) were not upheld. The data and analysis suggest that the deceased women and their relatives were unable to claim their

    A combined study of the geophysical survey and hydro-geochemistry in the Quaternary alluvial aquifers of Bhagalpur district from Bihar state in central Gangetic plain of India was carried out with the objective of identifying the geochemical processes and their relation with lithological profile. Results of resistivity survey validated with borehole lithology gave us a clear picture of the geological signature of the aquifers, which support the reducing nature of the aquifer where concentration of arsenic was high. Reducing nature of the aquifer environment was shown by water samples having relatively negative Eh value. From XRD study of the soil samples, it was found that goethite, dolomite, calcite, quartz and feldspar are the major minerals for most of the samples. Output of this work concludes that resistivity survey is an economically feasible tool which can be successfully used to target arsenic-safe aquifers on wide scale.

    Extreme rainfall events in the central Indian region are often related to the passage of synoptic scale monsoon low-pressure systems (LPS). This study uses the surrogate climate change method on ten monsoon LPS cases connected to observed extreme rainfall events, to investigate how sensitive the precipitation and runoff are to an idealized warmer and moister atmosphere. The ten cases are simulated with three different initial and lateral boundary conditions: the unperturbed control run, and two sets of perturbed runs where the atmospheric temperature is increased uniformly throughout the atmosphere, the specific humidity increased according to Clausius Clapeyron's relation, but the large-scale flow is unchanged. The difference between the control and perturbed simulations are mainly due to the imposed warming and feedback influencing the synoptic flow. The mean precipitation change with warming in the central Indian region is 18-20 %/K, with largest changes at the end of the LPS tracks. The LPS in the warmer runs are bringing more moisture further inland that is released as precipitation. In the perturbed runs the precipitation rate is increasing at all percentiles, and there is more frequent rainfall with very heavy intensities. This leads to a shift in which category that contributes most to the total precipitation: more of the precipitation is coming from the category with very heavy intensities. The runoff changes are similar to the precipitation changes, except the response in intensity of very heavy runoff, which is around twice the change in intensity of very heavy precipitation.

    SummaryA high concentration of Arsenic (As) contamination in ground water has been reported in the village of Kaudikasa in Rajnandgaon district, wherein around 10% of the population is suffering from As-borne diseases. The region does not share any demographic or geological similarity with the sedimentary aquifers of the Bengal Delta Plain in Eastern India, but represents an igneous terrain with elevated As concentrations in groundwater. There is limited information about the source of As in groundwater and its mobility constraints. In this area, almost all the wells are located in the granitic terrain with pegmatitic intrusions. Most of these wells are characterized by As concentration above the World Health Organization ( WHO, 1999) and the BIS (Bureau of Indian Standards) standards, with the highest being found in a well with more than 250 μg/L of As. Here we report petrographic studies of the granitic host rock and X-ray diffraction results that indicate that altered realgar (α-As 4S 4), para realgar (AsS), and/or tennantite (Cu 12As 4S 13), are the main mineral that contain As. This element is leached during the weathering and water-rock interactions. Microprobe analysis of the altered realgar grains of in pegmatitic intrusions of the host granite indicate 23-27 wt.% As. Remote sensing is useful to delineate the source of this contaminant, which appears to lie at the intersection of a mineralized NW-SE and N-S lineaments associated with the Kotri rift zone. These lineaments are structurally controlled as rifting followed by thrusting and other types of faulting caused left-lateral displacement of N-S Kotri lineament along a NW-SE fault plane showing sinistral shearing. This process caused water drainage in the areas to flow along these highly mineralized weak zones. Thus, the water becomes highly contaminated due to leaching of minerals at the intersection of these lineaments, clearly visible at two areas of high contamination that lie very near to this

    Objectives. To examine gender disparities in cognitive functioning in India and the extent to which education explains this disparity in later life. Methods. This study uses baseline interviews of a prospective cohort study of 1,451 community-residing adults 45 years of age or older in four geographically diverse states of India (Karnataka, Kerala, Punjab, Rajasthan). Data collected during home visits includes cognitive performance tests, and rich sociodemographic, health, and psychosocial variables. The cognitive performance tests include episodic memory, numeracy, and a modified version of the Mini-Mental State Examination. Results. We find gender disparity in cognitive function in India, and this disparity is greater in the north than the south. We also find that gender disparities in educational attainment, health, and social and economic activity explain the female cognitive disadvantage in later life. Discussion. We report significant gender disparities in cognitive functioning among older Indian adults, which differ from gender disparities in cognition encountered in developed countries. Our models controlling for education, health status, and social and economic activity explain the disparity in southern India but not the region-specific disparity in the northern India. North Indian women may face additional sources of stress associated with discrimination against women that contribute to persistent disadvantages in cognitive functioning at older ages.

    The changing epidemiology of malaria since 1975 was studied in a tribal forested belt of central India, Chhattisgarh state, which is the second most highly malarious state in India. Chhattisgarh, which accounts for 2% of the total population of the country, contributed >16% of the total malaria cases, 23% of Plasmodium falciparum, and 7% of deaths due to malaria in the country. Retrospective analysis further revealed that, in 1975--76, P. vivax was the predominant species (58%); however, since 1979, P. falciparum showed a steady upward trend (50%), and in 2002. P. vivax reduced to 28%. Between 1986 and 2000, P. falciparum cases reported by the National Anti Malaria Programme have increased 500%, and the number of deaths also showed a similar alarming increase. From 2000 to 2002, though the number of malaria infections and number of deaths declined sharply as a result of intensive intervention measures (30% and 95%, respectively), which included new drugs like Sulfadoxine Pyrimethamine and Arteether under Enhanced Malaria Control Programme, the proportion of P. falciparum has held steady without any decline. Moreover, along with Anopheles fluviatilis, the traditional vector in the forest, An. culicifacies has also established itself in the forest. The comeback of malaria and establishment of new vectors was largely due to the deterioration of health services along with emergence of resistance in P. falciparum to Chloroquine and in An. culicifacies to DDT. Therefore, a more diversified malaria control program might be needed for sustainable malaria control. PMID:15631069

    The depth to the bottom of the magnetic sources (DBMS) has been estimated from the aeromagnetic data of Central India. The conventional centroid method of DBMS estimation assumes random uniform uncorrelated distribution of sources and to overcome this limitation a modified centroid method based on scaling distribution has been proposed. Shallower values of the DBMS are found for the south western region. The DBMS values are found as low as 22 km in the south west Deccan trap covered regions and as deep as 43 km in the Chhattisgarh Basin. In most of the places DBMS are much shallower than the Moho depth, earlier found from the seismic study and may be representing the thermal/compositional/petrological boundaries. The large variation in the DBMS indicates the complex nature of the Indian crust.

    Tree-ring-width index chronologies of teak ( Tectona grandis L.F.) from three sites in central India have been studied for their dendroclimatic potential. The existence of good correlation among the three site chronologies indicates the influence of common forcing factor to the tree growth of the region. Tree growth and climate relationship based on correlation analysis revealed the important contribution of moisture index and rainfall rather than the direct influence of the temperature on tree growth during different seasons. Significant positive relationship of moisture index and rainfall during the monsoon months as well as on the annual scale with tree-ring width variations over the region indicates the important role of moisture availability at the root zone. The results suggest that the teak tree-ring chronologies can be used as high resolution proxy for past precipitation and moisture level in the environment.

    Better constraining the geological evolution of the India-Asia suture zone is vital to our comprehension of the Himalayan-Tibetan orogen. This study presents new mapping, igneous U-Pb geochronology, and detrital zircon geochronology from suture zone rocks exposed in the Lopu Kangri Range. Located ~50 km NW of Saga in south-central Tibet, this range exposes a >1.5 km thick panel of suture zone architecture that was exhumed by late Cenozoic orogen-parallel extension across two N-S, moderate-angle normal faults. The Lopu Kangri Range and its surroundings expose all of the major suture-zone assemblages. In the north, Cretaceous--Eocene Gangdese arc granitoids are unconformably overlain by nonmarine, conglomerate-bearing strata of the Eocene (?)--Miocene Kailas Fm. Metaconglomerate exposed in the same structural position within the Range contains garnet porphyroblasts. Gangdese arc and metaconglomerate rocks are confined to the footwall of the north-directed Great Counter Thrust system, which carried Cretaceous-Early Eocene Xigaze forearc, suture zone mélange, and Indian passive margin (Tethyan) strata northwards across three major NE-SW fault strands during the Miocene. Tethyan strata in the Range consist of locally garnet- and sillimanite-bearing calc-gneiss and schist that display N-S stretching lineations and top-N s-c fabrics. These rocks are exposed in the southern half of the range beneath suture zone mélange in the footwall of a moderately N-dipping, normal-sense shear zone. Six detrital zircon samples from the Xigaze forearc, metaconglomerate and meta-Tethyan strata were analyzed to confirm our lithologic correlations and provenance interpretations made in the field. 12 igneous U-Pb samples were analyzed to characterize granitoids that intrude the Range. They reveal a suite of 50-40 Ma granitoids that display a general younging trend from north to south across the suture. Five samples of 35-10 Ma leucogranites contain inherited zircon cores whose age spectra

    Groundwater forms a major source of drinking water in most parts of the world. Due to the lack of piped drinking water supply, the population in rural areas depend on the groundwater resources for domestic purposes. Hence, the quality of groundwater in such regions needs to be monitored regularly. Presence of high concentration of nitrate in groundwater used for drinking is a major problem in many countries as it causes health related problems. Most often infants are affected by the intake of high nitrate in drinking water and food. The present study was carried out with the objective of assessing the nitrate concentration in groundwater and determining the causes for nitrate in groundwater in parts of Nalgonda district in India which is located at a distance of about 135 km towards ESE direction from Hyderabad. Nitrate concentration in groundwater of this area was analysed by collecting groundwater samples from forty six representative wells. Samples were collected once in two months from March 2008 to March 2009. A total of 244 groundwater samples were collected during the study. Soil samples were collected from fifteen locations during May 2009 and the denitrifying bacteria were isolated from the soil using spread plate method. The nitrate concentration in groundwater samples were analysed in the laboratory using Metrohm 861 advanced compact ion chromatograph using appropriate standards. The highest concentration of nitrate recorded during the sampling period was 879.65mg/l and the lowest concentration was below detection limit. The maximum permissible limit of nitrate for drinking water as per Bureau of Indian Standards is 45mg/l. About 13% of the groundwater samples collected from this study area possessed nitrate concentration beyond this limit. The nitrate concentration was high in the southeastern part of the study area. This implies that the nitrate concentration in groundwater tends to increase along the flow direction. Application of fertilizers is one

    Inhalant use by children leads to poor performance in school and has been observed to precede substance use later in life. There is paucity of data on inhalant use among school children in India, particularly in the Northeast region of the country. We determined the prevalence and documented inhalant use characteristics among schoolchildren in the Northeast region of India. This cross sectional study was conducted in six states in the Northeast region of India. Schoolchildren between eighth and eleventh standards from the capital areas of the states were included in the study. Data were collected using a questionnaire. Analysis was done using descriptive statistics and Chi-square test. Of the 4074 enrolled students, data from 3943 students who responded to the inhalant use question were analyzed. Mean age was 14.8 ± 1.2 years and 51.2% of participants were male. The proportion of students who had ever used inhalants (ever user) was 18.8% and adhesive/glue was the inhalant misused by most of the students. A higher proportion of males than females were ever users (P ≤ 0.001) and the most common place of use was at home (33.1%). Being in the presence of an older person using an inhalant or tobacco was found to be associated with use of inhalants among students. Nearly one-fifth of the students had used inhalants and nearly half used inhalants in the past month. Sensitization of the parents and school authorities to the problem, as well as preventive and curative services, should be considered. PMID:24250225

    Determining the frequency, magnitude and causes of large floods over long periods in the flood-prone Himalaya is important for estimating the likelihood of future floods. A thousand year record (with some information from 2600 years ago) of the frequency and some estimates of velocities and discharges of large floods has been reconstructed in the Upper Ganga catchment, India, using written reports, litho-stratigraphy and sedimentology, and dated by optical and radiocarbon methods. In the Upper Ganga catchment rainfall triggers large landslides that dam rivers and release large amounts of water when they burst, thereby amplifying the effects of rainfall. The large floods in the catchment may be the result of landslide dam bursts rather than glacial lake bursts, and these are likely to continue and possibly worsen as the monsoon intensifies over the next century. However preliminary information suggests that the recent devastating flood of June 2013 was the result of heavy rainfall not landslide dam bursts. The frequency record is non-random and shows a high frequency between AD 1000 and AD 1300 (omitting uncertainties), then a low frequency until a cluster of floods occurred about 200 years ago, then increased frequency. This temporal pattern is like but not identical with that in Peninsular India, and both appear to be the result of variations in the monsoon.

    The size distributions of aerosols can provide evidences for their sources and formation processes in the atmosphere. Size-segregated aerosols (9-sizes) were collected in urban site (Raipur: 21.2°N and 82.3°E) in central India during winter of 2012-2013. The samples were analyzed for dicarboxylic acids (C2-C12), ω-oxocarboxylic acids (ωC2-ωC9), pyruvic acid and α-dicarbonyls (C2-C3) as well as elemental carbon (EC), organic carbon (OC), water-soluble OC (WSOC) and inorganic ions. Diacids showed a predominance of oxalic acid (C2) followed by succinic and azelaic acid whereas ω-oxoacids exhibited a predominance of glyoxylic acid and glyoxal was more abundant than methylglyoxal in all the sizes. Diacids, ω-oxoacids and α-dicarbonyls showed bimodal size distribution with peaks in fine and coarse modes. High correlations of fine mode diacids and related compounds with potassium and levoglucosan suggest that they were presumably due to a substantial contribution of primary emission from biomass burning and secondary production from biomass burning derived precursors. High correlations of C2 with higher carbon number diacids (C3-C9) suggest that they have similar sources and C2 may be produced via the decay of its higher homologous diacids in fine mode. Considerable portions of diacids and related compounds in coarse mode suggest that they were associated with mineral dust particles by their adsorption and photooxidation of anthropogenic and biogenic precursors via heterogeneous reaction on dust surface. This study demonstrates that biomass burning and dust particles are two major factors to control the size distribution of diacids and related compounds in the urban aerosols from central India.

    Singing performance is based on the efficiency of the respiratory system. The present study was aimed to evaluate the results of pulmonary function tests (PFTs) in female singers of Kolkata, India and to compare the data with their sedentary counterparts from India and abroad. The study was also aimed to propose prediction norms for PFTs in both the groups. Fifty-six female singers and fifty-two female non-singers (control group) with similar socioeconomic backgrounds were randomly sampled from the Rabindrabharati University, Kolkata. Pulmonary function tests were conducted by an Expirograph and the peak expiratory flow rate (PEFR) was measured by Wright's peak flow meter. PFTs were significantly higher in singers than in their control group. The correlation matrix depicted a significant relationship of physical parameters (age, body height and body weight) with vital capacity (VC), forced vital capacity (FVC), forced expiratoty volume in 1 second (FEV1) and PEFR in both groups. Regression equations were computed to predict PFTs from physical parameters and duration of invovlement in singing training. The results indicated that female singers of Kolkata had higher lung capacity than their non-singer counterparts probably because of their regular practice and training of singing that required imperative effort of the respiratory system.

    Since the beginning of the Safe Motherhood Initiative, India has accounted for at least a quarter of maternal deaths reported globally. India's goal is to lower maternal mortality to less than 100 per 100,000 livebirths but that is still far away despite its programmatic efforts and rapid economic progress over the past two decades. Geographical vastness and sociocultural diversity mean that maternal mortality varies across the states, and uniform implementation of health-sector reforms is not possible. The case study analyzes the trends in maternal mortality nationally, the maternal healthcare-delivery system at different levels, and the implementation of national maternal health programmes, including recent innovative strategies. It identifies the causes for limited success in improving maternal health and suggests measures to rectify them. It recommends better reporting of maternal deaths and implementation of evidence-based, focused strategies along with effective monitoring for rapid progress. It also stresses the need for regulation of the private sector and encourages further public-private partnerships and policies, along with a strong political will and improved management capacity for improving maternal health.

    Sausar Fold Belt (SFB) in central India forms the southern part of the Central Indian Tectonic Zone (CITZ) - a crustal scale Proterozoic mobile belt dissecting the Indian craton, whose tectonothermal history and age is important for understanding the Proterozoic crustal history of the Indian craton. SFB comprises a gneissic basement (TBG: Tirodi Biotite Gneiss) overlain by a supracrustal sequence of quartzite-pelite-carbonate (SSG: Sausar Group). SSG and TBG are deformed and metamorphosed in greenschist to amphibolite facies. Two phases of granite intrusion are observed in the SSG - a syntectonic foliated granite and a post-tectonic massive granite, with clear structural relationship with the host rocks. Monazite chemical dating (U-Th-total Pb) of the foliated and massive granites yield Neoproterozoic (ca. 945-928 Ma) ages that contradict many earlier geochronological interpretations. Foliated granites and the immediately adjacent TBG show monazite grains with ca. 945 Ma mean age, interpreted as the timing of D2 deformation and amphibolite facies metamorphism of SSG. The post tectonic granites intruded these rocks around 928 Ma, and were largely undeformed. A terminal thermal overprint is found in some monazite grain rims at ca. 785 Ma age. The younger Sausar tectonothermal events have overprinted the adjacent high-grade granulites of Ramakona-Katangi Granulite (RKG) belt, and should not be considered as parts of the same tectonothermal event representing different depth sections only.

    Peste-des-petits-ruminants (PPR), bluetongue (BT) and goatpox (GP) have been well recognized as causes of significant economic losses in the small ruminant population of Asia and Africa. We describe here the occurrence of these three in an outbreak noticed in non-descript goats from a subtropical region of central India. An investigation was carried out to confirm the aetiology of the heavy mortality in goats (74.6%, 112/150), with testing of samples from 12 surviving animals exhibiting mixed clinical signs indicative of PPR, BT and GP. Sandwich ELISA was used to detect PPR virus antigen and competition ELISA to detect PPR virus and BT virus antibodies. GP was confirmed on the basis of nodular lesions and an immunodiffusion assay. Eight of the 12 affected animals (66.7%) were positive for PPR virus and BT virus antibodies, and two goats (16.7%, 2/12) exhibiting clinical lesions of pox were also found positive for PPR virus/antibodies and BT virus antibodies, respectively. Although BT virus could not be identified in any sample, detection of BT virus antibodies indicated previous or possibly concurrent infection with BT virus in these goats. The N-gene-based RT-PCR was used to confirm the PPR infection in these goats, and one of the amplicons was sequenced. The sequence and phylogenetic analysis revealed close proximity to PPR virus isolates from Tibet and China, with sequence homology of up to 96.9%. The sequence homology was relatively low with the majority of other Indian isolates (72.7-93.5%). The detection of this new PPR virus sequence indicates the circulation of cross-border strains in this region of India. It is presumed that the heavy mortality observed in goats is possibly attributable to the occurrence of mixed infection of PPR and GP, or PPR, BT and GP. PMID:21235732

    Aim: The aim of the current cross-sectional study was to assess oral mucosal lesions among psychiatric jail patients residing in central jail, Bhopal, Madhya Pradesh, India. Materials and Methods: The study subjects consisted of prediagnosed psychiatric patients residing in central jail, Bhopal. A matched control consisting of cross section of the population, that is, jail inmates residing in the same central jail locality was also examined to compare the psychiatric subjects. The WHO oral health assessment proforma, 1997 along with 18-item questionnaire was used for the oral health examination. Results: A total number of subjects examined were 244, which comprised of 122 psychiatric inmates and 122 nonpsychiatric inmates. Among all psychiatric inmates, about 57.4% of inmates had a diagnosis of depression, 14.8% had psychotic disorders (like schizophrenia), and 12.3% had anxiety disorder. A total of 77% study inmates, which comprised of 87.7% psychiatrics and 66.4% nonpsychiatrics had a habit of tobacco consumption (smokeless or smoking). Overall prevalence of oral mucosal lesions among the inmates was 85 (34.8%), which comprised of 39.3% psychiatric inmates and 30.3% nonpsychiatric inmates. Conclusion: The information presented in this study adds to our understanding of the common oral mucosal lesions occurring in a psychiatric inmate population. Leukoplakia and oral submucous fibrosis were the most common types of oral mucosal lesions found. Efforts to increase patient awareness of the oral effects of tobacco use and to eliminate the habit are needed to improve oral and general health of the prison population. PMID:25316937

    The depth to the bottom of the magnetic sources (DBMS) may be used as an estimate of the Curie - point depth. The DBMSs can also be interpreted in term of thermal structure of the crust. The thermal structure of the crust is a sensitive parameter and depends on the many properties of crust e.g. modes of deformation, depths of brittle and ductile deformation zones, regional heat flow variations, seismicity, subsidence/uplift patterns and maturity of organic matter in sedimentary basins. The conventional centroid method of DBMS estimation assumes random uniform uncorrelated distribution of sources and to overcome this limitation a modified centroid method based on fractal distribution has been proposed. We applied this modified centroid method to the aeromagnetic data of the central Indian region and selected 29 half overlapping blocks of dimension 200 km x 200 km covering different parts of the central India. Shallower values of the DBMS are found for the western and southern portion of Indian shield. The DBMSs values are found as low as close to middle crust in the south west Deccan trap and probably deeper than Moho in the Chhatisgarh basin. In few places DBMS are close to the Moho depth found from the seismic study and others places shallower than the Moho. The DBMS indicate complex nature of the Indian crust.

This shallowing-upward sequence was interpreted to be deposited close to the crest of the forebulge when it passed through the area of Tingri. 4) The change in sedimentation between the Zhepure Shanpo and Zhepure Shanbei formations could represent the transition from Indian passive margin to onset of Himalayan foreland basin deposition. Our data indicated that onset of Himalayan foreland basin and India-Asia initial collision in central Himalaya could be happed as early as at latest Campanian (~72 Ma).

    This paper examines the extent of pollution in Hudiara drain water due to untreated industrial and sewage waste of India and Pakistan. Ninety-nine surface water samples from the Pakistani side of the Hudiara drain were collected during September 1997, and April and June 1998. The analytical results of the Hudiara drain samples point out the industrial and sewage inputs from India and Pakistan. Higher values of biochemical oxygen demand (BOD), chemical oxygen demand(COD), total organic carbon(TOC), and trace metals in drain samples from the Indo-Pak border clearly indicate the Indian industrial and sewage pollution. Large variations in the levels of various measured parameters (COD, BOD, TOC, pH, total soluble substances, and trace metals) were observed along the Hudiara drain in the Pakistani vicinity. These variations were due to different types of industrial effluents and small village drains. The study showed that suspended solids(SS), COD, and fecal coliform (FC) were the major pollutants. Accordingly, the most feasible alternative is to convert the drainage network to a sedimentation and temporary storage reservoir. If disinfected, the runoff water can be used for restricted irrigation. Groundwater samples taken from the drain's surrounding area have also been analyzed. Thirty percent of the samples are not fit for drinking purposes due to NO3-N, Se and FC counts as prescribed by World Health Organization (WHO) guidelines. A trilinear diagram clearly indicates the influence of surface water of the Hudiara drain on ground water; moreover, higher values of nitrate and FC clearly indicate the seepage from the Hudiara drain.

    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.

    Crustal deformation models of the Tibetan plateau are assessed by investigating the nature of Neogene deformation along the India-Asia suture zone through geologic mapping in south-central Tibet (84°30'E). Our mapping shows that the suture zone is dominated by a system of 3 to 4 ENE-striking, south-dipping thrust faults, rather than strike-slip faults as predicted by models calling upon eastward extrusion of the Tibetan plateau. Faults along the suture zone are not active, as they are cut by a system of NNW-striking oblique slip normal faults, referred to herein as the Lopukangri fault system. Fault-slip data from the Lopukangri fault system shows that the mean slip direction of its hanging wall is N36W. We estimate the net slip on the Lopukangri fault by restoring components of the thrust system. We estimate that the fault has accommodated ˜ 7 km of right-slip and ˜ 8 km of normal dip-slip, yielding a net slip of ˜ 10.5 km, and 6 km of horizontal east-west extension. The Lopukangri fault system is active and geomorphic offsets indicate right separations and westside-down dip-separation. The mapview curviplanar geometry and geomorphic expression of the Lopukangri fault system is similar to faults and rift basins to its east and west. These extensional faults are en echelon in map view and encompass a region that is 200 km long (east-west) and 95 km wide (north-south). Assuming our results for the Lopukangri fault are applicable to the entire system, we estimate a maximum of 18% extension across the zone. All active faults in the system terminate southward adjacent to the India-Asia suture zone. Because the individual rift geometries are similar and suggest a common kinematic relationship, we propose that the extensional system formed as a trailing extensional imbricate fan at the southern termination of the central Tibet conjugate fault zone. Alternatively, the extensional system may terminate to the north and represent a group of isolated crustal tears. Both

    The northern part of Central India Tectonic Zone (CITZ) is delineated by an arc-shaped supracrustal belt commonly referred to as Mahakoshal Belt, which is considered as a product of intense rifting of sialic crust that occurred at ca 2400-2600 Ma. Several granitoid plutons intrude the Parsoi Formation of Mahakoshal Belt. Among these, an elliptical small stock-like granitoid body trending E-W is exposed in and around Jhirgadandi region of Mahakoshal Belt, referred herein as Jhirgadandi Pluton. It is composed of minor amount of mafic rocks (diorite) and predominant granitoids. Country-rock pelitic xenoliths and microgranular enclaves (ME) are commonly hosted in granitoids but are absent in diorite. The ME exhibit typical magmatic texture with a Bt(±Cpx ± Hbl)-Pl-Kf-Qtz-Mag-Ap assemblage, similar to that in host granitoids but with contrasting mineral proportions. Whole-rock molar Al2O3/(CaO + Na2O + K2O) (A/CNK) ratios of diorite (0.63-0.72), ME (0.69-1.21) and granitoids (0.83-1.05) suggest their nature largely metaluminous (I-type) to rarely peraluminous (S-type) granitoids. On most binary plots involving silica, two distinct compositional paths can be recognized; one formed by an array of differentiating diorite and ME, and another by fractionating granitoids gradually depleting in compatible elements. It is most likely that ME were generated by progressive and concurrent mixing of coeval pristine mafic (diorite) and granitoid magmas and fractionation processes. However, coherent and identical trace elements (except for Sr, Th, Y and Ni) and REE patterns for ME-granitoid pairs most likely suggest partial to near-complete chemical equilibration through varying degrees of diffusion process across the ME - partly crystalline host granitoid boundary. High-precision U-Pb SHRIMP zircon 206Pb/238U ages for ME (1758 ± 19 Ma) and host granitoid (1753 ± 9.1 Ma) from Jhirgadandi Pluton further support the notion that they were coeval. The obtained age (˜1750 Ma) of

    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.

    Using an organism living in situ for monitoring is referred as passive monitoring. Lepraria lobificans Nyl., a leprose lichen growing naturally on monuments and buildings in the city Mandav in central India is used for passive monitoring of atmospheric metals. Seven metals (Cd, Cr, Ni, Al, Fe, Cu, and Zn) were analyzed. Samples collected from road site exhibit the maximum concentration of Fe, Cd, Cr, Ni, and Zn. Iron exhibit maximum accumulation both in lichen thallus and the substratum with mean values of 2,195.63 microg g(-1) dry weight. As compared with other growth form of lichens, L. lobificans exhibits the higher accumulation of Fe than foliose and fruticose lichens. On the basis of these results, it can be hypothesized that L. lobificans is an excellent accumulator of different metals. The statistical analysis applied to the element concentration between the metals as well as between the sites by analysis of variance found the difference to be significant at 1% and 5%, respectively. Student-Newman-Keuls test also shows significant difference for iron between the different metals. PMID:19496009

    A fossil assemblage of soft-bodied megascopic metazoans possessing faunistic, ecological and taphonomic affinities to known classical Ediacaran assemblages has been discovered from the Proterozoic Vindhyan Basin of India. The assemblage is represented by nine coelenterate genera ( Tribachidium, Eoporita, Kaisalia, Cyclomedusa, Ediacaria, Nimbia, Paliella, Medusinites and Hiemalora), one arthropod genus Spriggina and a few unnamed possible new forms belonging to sponge and coelenterate. These fossils show facies-controlled temporal distribution forming two fossil zones: F 1 and F 2 located, respectively, in the Lakheri and Sirbu Formations (Bhander Group). A majority of them is common to the Ediacara assemblages of several continents, thereby suggesting their global biogeographic distribution. F 1 and F 2 in the local stratigraphy are separated by a thick stromatolitic carbonate facies devoid of metazoan remains. The Vindhyan Ediacara and host rock sequences reveal energetic (wave-tide-storm induced), shallow marine and near-shore environments of deposition of siliciclastic terrigenous facies. The carbonate facies parting suggests interruption of typical Ediacara environments by a broad spell of lime-rich quieter water settings favoring selective growth of metaphytes. The Vindhyan fossils show both Nemiana (higher relief forms without finer features in sandstones, e.g. Cyclomedusa and Ediacaria) and Beltanelliformis (lower relief forms with finer features in shales, e.g. Kaisalia and Hiemalora) types of preservation. Wide biogeography and ecological uniformity qualify the Vindhyan fossils as biostratigraphically significant group that fixes the age of the Lakheri-Sirbu segment at latest Neoproterozoic, helps in intercontinental correlation of the Bhander Group and focuses supra-Sirbu sequence as potential bearer of early Cambrian organic signatures.

    A series of false color composite images covering the volcanic cordillera was written. Each image is 45 km (1536 x 1536 pixels) and was constructed using bands 7, 4, and 2 of the Thematic Mapper (TM) data. Approximately 100 images were prepared to date. A set of LANDSAT Multispectral Scanner (MSS) images was used in conjunction with the TM hardcopy to compile a computer data base of all volcanic structure in the Central Andean province. Over 500 individual structures were identified. About 75 major volcanoes were identified as active, or potentially active. A pilot study was begun combining Shuttle Imaging Radar (SIR) data with TM for a test area in north Chile and Bolivia.

    Leaf growth patterns were investigated in 11 evergreen (with leaf life-spans of just more than 1 year) and 15 deciduous species, occurring along an elevational gradient of 600-2200 m elevation in the Central Himalaya. Records were made of the leaf initiation period, leaf population dynamics, leaf expansion, leaf mass changes, leaf longevity and related parameters. Species of both groups produced leaves at similar rates during March to April, the driest period of the year. Species of both groups had approximately fully developed foliage during the warm, wet period (mid-June to mid-September) of the monsoon. However, significant differences were found at group level in other characters: shoot length (19.5 cm per shoot for deciduous and 11.7 cm for evergreen species); leaf population per 10 cm shoot length (4.7 vs 15.0); leaf area (107.9 vs 41.4 cm2/ leaf); specific leaf mass (106.9 vs 191.3 g/m2); and leaf mass loss after the monsoon period, being rapid and higher (31.6%) in deciduous species and slow and limited in the evergreens (26.2%). However, species of the two groups showed considerable overlaps in the values of above characters. The evergreen species of the Central Himalaya resembled the deciduous species of the region more than the multi-year leaves of clearly evergreen species. The evergreens bear leaves throughout the year, but like deciduous species bear the cost of annual replacement of old leaves by new leaves. They seem to outcompete deciduous species by producing annually a greater mass of leaves of low-carbon cost (per unit leaf mass), which is capable of conducting photosynthesis all year round. A situation of less marked contrast between favourable and nonfavourable periods, with respect to temperature, seems to favour the leaf characters of the evergreens.

    India was affected by a major outbreak of chikungunya fever caused by Chikungunya virus (CHIKV) during 2006-2007. Kerala was the worst affected state during 2007 with a contribution of 55.8% suspected cases in the country. However, except for clinically reported case records, no systematic information is available on infection status of CHIKV in the region. Hence, we carried out a post-epidemic survey to estimate seroprevalence status [immunoglobulin G (IgG)] in the community using commercially available indirect immunofluorescence test. This methodology had been reported to be highly specific and sensitive for CHIKV infection. The study area selected was the worst affected mid-highlands region of Kerala which harbour vast area of rubber plantations. The study evidenced 68% of the population to be seropositive for CHIKV IgG. Males were found more affected than females (χ2 = 9.86; p = 0.002). Among males, prevalence was significantly higher in the age classes 21-30 (χ2 = 5.46; p = 0.019) and 31-40 (χ2 = 5.84; p = 0.016) years. This may be due to high occupational risk of the male population engaged in plantation activities exposed to infective bites of Aedes albopictus. The current study provides an insight into the magnitude of CHIKV outbreak in Kerala. PMID:22241110

    Aims and Objectives: To describe clinicopathological features of surgically resected vascular malformations (VMs) of central nervous system (CNS). Materials and Methods: Histologically diagnosed cases of VMs of CNS during April 2010–April 2014 were included. Demographic data, clinical and radiological features were obtained. Hematoxylin and eosin slides were reviewed along with Verhoeff-Van Gieson (VVG), Masson's trichrome, periodic acid-Schiff, and Perls' stains. Morphologically, cavernomas and arteriovenous malformations (AVMs) were distinguished on the basis of vessel wall features on VVG and intervening glial parenchyma. Results: Fifty cases were diagnosed as VMs of CNS with an age range of 14–62 years. These included 36 cavernomas, 12 AVMs, 2 mixed capillary-cavernous angiomas. Most of the cavernoma patients (15/36) presented with seizures, whereas AVM patients (8/12) had a headache as the dominant symptom. Twenty-nine patients were reliably diagnosed on radiological features. Microscopic evidence of hemorrhage was seen in 24/36 cavernomas and 6/12 AVMs, as opposed to radiologic evidence of 10 and 4, respectively. Reactive gliosis was seen in 16 cavernomas. Conclusions: Histological features are important for classifying the VMs of CNS as there are no specific clinical and radiological features. Type of VM has a bearing on management, prognosis, and risk of hemorrhage. PMID:27114659

    Today, most wild tigers live in small, isolated Protected Areas within human dominated landscapes in the Indian subcontinent. Future survival of tigers depends on increasing local population size, as well as maintaining connectivity between populations. While significant conservation effort has been invested in increasing tiger population size, few initiatives have focused on landscape-level connectivity and on understanding the effect different landscape elements have on maintaining connectivity. We combined individual-based genetic and landscape ecology approaches to address this issue in six protected areas with varying tiger densities and separation in the Central Indian tiger landscape. We non-invasively sampled 55 tigers from different protected areas within this landscape. Maximum-likelihood and Bayesian genetic assignment tests indicate long-range tiger dispersal (on the order of 650 km) between protected areas. Further geo-spatial analyses revealed that tiger connectivity was affected by landscape elements such as human settlements, road density and host-population tiger density, but not by distance between populations. Our results elucidate the importance of landscape and habitat viability outside and between protected areas and provide a quantitative approach to test functionality of tiger corridors. We suggest future management strategies aim to minimize urban expansion between protected areas to maximize tiger connectivity. Achieving this goal in the context of ongoing urbanization and need to sustain current economic growth exerts enormous pressure on the remaining tiger habitats and emerges as a big challenge to conserve wild tigers in the Indian subcontinent.

    Black carbon (BC) particles play a unique and important role in earth's climate system. BC was measured (in-situ) in the central part of the Indo-Gangetic Plains (IGP) at Varanasi, which is a highly populated and polluted region due to its topography and extensive emission sources. The annual mean BC mass concentration was 8.92 ± 7.0 µg m -3, with 34% of samples exceeding the average value. Seasonally, BC was highest during the post-monsoon and winter periods (approximately 18 µg m -3) and lower in the premonsoon/ monsoon seasons (approximately 6 µg m -3). The highest frequency (approximately 46%) observed for BC mass was in the interval from 5 to 10 µg m -3. However, during the post-monsoon season, the most common values (approximately 23%) were between 20 and 25 µg m -3. The nighttime concentrations of BC were approximately twice as much as the daytime values because of lower boundary layer heights at nighttime. The Ångström exponent was significantly positively correlated (0.55) with ground-level BC concentrations, indicating the impact of BC on the columnar aerosol properties. The estimated mean absorption Ångström exponent was 1.02 ± 0.08 µg m -3, indicating that the major source of BC was from fossil fuel combustion. Significant negative correlations between BC mass and meteorological parameters indicate a pronounced effect of atmospheric dynamics on the BC mass in this region. The highest mean BC mass concentration (18.1 ± 6.9 µg m -3) as a function of wind speed was under calm wind conditions (38% of the time).

    Gujarat state of India has come a long way in improving the health indicators since independence, but progress in reducing maternal mortality has been slow and largely unmeasured or documented. This case study identified several challenges for reducing the maternal mortality ratio, including lack of the managerial capacity, shortage of skilled human resources, non-availability of blood in rural areas, and infrastructural and supply bottlenecks. The Gujarat Government has taken several initiatives to improve maternal health services, such as partnership with private obstetricians to provide delivery care to poor women, a relatively-short training of medical officers and nurses to provide emergency obstetric care (EmOC), and an improved emergency transport system. However, several challenges still remain. Recommendations are made for expanding the management capacity for maternal health, operationalization of health facilities, and ensuring EmOC on 24/7 (24 hours a day, seven days a week) basis by posting nurse-midwives and trained medical officers for skilled care, ensuring availability of blood, and improving the registration and auditing of all maternal deaths. However, all these interventions can only take place if there are substantially-increased political will and social awareness. PMID:19489418

    Thunderstorm, resulting from vigorous convective activity, is one of the most spectacular weather phenomena in the atmosphere which is associated with thunder, squall lines and lightening. On 13 April 2010, a severe storm struck parts of Bangladesh and eastern India which lasted about 90 minutes, with the most intense portion spanning 30-40 minutes. The severe Thunderstorm on 13th April 2010 spawned a large tornado, which lasted about 20 minutes and was the first tornado recorded in Bihar history. In the year 2015, Bihar experienced a similar storm on 21 April during which multiple microbursts were observed. Various meteorological parameters have been analyzed to study the factors affecting the development of the thunderstorm. Satellite images from KALPANA and Meteosat has been analyzed to capture the temporal and spatial evolution of these storms. The satellite images show the development of a convective clouds system in the early afternoon hours which developed further into the severe storms by late evening. The analysis carried out further using K-index, lifted index, CAPE etc also shows the development of multiple cells of convection. Further analysis of these storms is presented in the paper.

The circulating CHIKV strains were of Indian Ocean Lineage (IOL) group within the East, Central, and South African (ECSA) genotype. However few amino acid changes were observed in E1 polypeptide with reference to African strain S-27 (AF369024). Further studies are needed to know the implications of these changes in vector-pathogen compatibility and host-pathogen interactivity. As a whole, this study highlighted the proportion of CHIKV cases, lineage of causative strain and evolutionary pattern of circulating strain in terms of amino acid changes in the structural protein.

    The Mesozoic Gondwanan Satpura Basin of central India, comprising an approximately 1300 m thick sequence of the Pachmarhi, Denwa and Bagra Formations, was subjected to at least three major tectonic events. These events are manifested by tectonic dislocation, marginal uplifts, basin subsidence and deformation, as well as by stratigraphical disposition, lithofacies assemblage, and palaeoslope and pal˦ocurrent patterns. The first tectonic event is manifested by the onset of Early Triassic Pachmarhi sedimentation, which is marked in the basal part by a sudden increase of conglomeratic, pebbly, gritty to coarsegrained cross-bedded sandstone. This contrasts with the underlying fine elastics of the Late Permian Bijori Formation. The stratigraphical relationship and lithofacies, together with pal˦ocurrent and petrographic data, reflect tectonic uplift in the source area to the southeast of the Satpura Basin during or prior to the deposition of Pachmarhi Formation. The pebbly coarse sandy facies of the Pachmarhi Formation represents a braided river assemblage, overlain by a meandering river facies of the Denwa Formation, with river systems flowing dominantly from southeast to northwest. The progressive change in lithofacies and grain size upward from Pachmarhi to Denwa implies that the source area became peneplained and that the basin stabilised. During the prolonged gap of non-deposition, following the Mid-Triassic break in sedimentation after deposition of the Denwa Formation, a second tectonic event resulted in the widespread faulting and uplift of Permo-Triassic Gondwana sediments and basement rocks, respectively, to the south and north of the Narmada-Son Lineament Zone of Peninsular India. A third tectonic event is manifested by Late Jurassic-Early Cretaceous Bagra conglomerate and sandstone-shale facies in the northern part of the Satpura Basin. This formation, which unconformably overlies the Precambrian, and Permian and Triassic Gondwana formations or abuts

    Background: Dental anxiety is a major barrier for dental care utilization. Hence, identifying anxious individuals and their appropriate management becomes crucial in clinical practice. Aim: The study aims to assess dental anxiety, factors influencing dental anxiety, and anxiety towards tooth extraction procedure among patients attending a dental hospital in India. Materials and Methods: The study sample consisted of 1,148 consecutive patients aged 18-70 years. The assessment tools consisted of a consent form, history form, a questionnaire form containing the Modified Dental Anxiety Scale (MDAS) which was used to assess the level of dental anxiety, and an additional question on anxiety towards dental extraction procedure. Results: Among the study group, 63.7% were men and 36.3% were women. Based on the MDAS score, 45.2% of the participants were identified to be less anxious, 51.8% were moderately or extremely anxious, and 3% were suffering from dental phobia. Mean MDAS total score was 10.4 (standard deviation (SD) = 3.91). Female participants and younger subjects were more anxious (P < 0.001). Subjects who were anxious had postponed their dental visit (P < 0.001). Participants who had negative dental experience were more anxious (P < 0.05). Notably, 82.6% reported anxiety towards extraction procedure. Significant association was seen between anxiety towards extraction procedure and the respondents gender (P < 0.05), age (P < 0.001), education level (P < 0.05), employment status (P < 0.001), income (P < 0.001), self-perceived oral health status (P < 0.05), and their history of visit to dentist (P < 0.05). Conclusion: Significant percentage of population was suffering from dental anxiety in this study population. A plethora of factors like age, gender, education level, occupation, financial stability, and previous bad dental experience influences dental anxiety to various levels.

    The rate and intensity of land use land cover (LULC) change has increased considerably during the past couple of decades. Mining brings significant alterations in LULC specifically due to its impact on forests. Parts of Central India are well endowed with both forests and minerals. Here, the conflict between human interests and nature has intensified over time. Monitoring and assessment of such conflicts are important for land management and policy making. Remote sensing and Geographical Information System have the potential to serve as accurate tools for environmental monitoring. Understanding the importance of landscape metrics in land use planning is challenging but important. These metrics calculated at landscape, class, and patch level provide an insight into changing spatiotemporal distribution of LULC and ecological connectedness. In the present study, geospatial tools in conjunction with landscape metrics have been used to assess the impact of coal mining on habitat diversity. LULC maps, change detection analysis, and landscape metrics have been computed for the four time periods (1972, 1992, 2001, and 2006). There has been a significant decline in forest cover especially of the Sal-mixed forests, both in area as well as quality, due to flouted mining regulations. Reclamation of mined lands has also been observed in some of the areas since 2001. PMID:19908153

    We have carried out radioelemental (232Th, 238U, 40K), petrological and geochemical analyses on granitoids and gneisses covering major rock formations of the Bundelkhand craton, central India. Our data reveal that above characteristics are distinct among granitoids (i.e. pink, biotite and grey granitoids) and gneisses (i.e. potassic and sodic types). Pink granitoid is K-feldspar-rich and meta-aluminous to per-aluminous in character. Biotite granitoid is meta-aluminous in character. Grey granitoid is rich in Na-feldspar and mafic minerals, granodiorite to diorite in composition and meta-aluminous in character. Among these granitoids, radioelements (Th, U, K) are highest in pink granitoid (45.0 ± 21.7 ppm, 7.2 ± 3.4 ppm, 4.2 ± 0.4 %), intermediate in biotite granitoid (44.5 ± 28.2 ppm, 5.4 ± 2.8 ppm, 3.4 ± 0.7 %) and lowest in grey granitoid (17.7 ± 4.3 ppm, 4.4 ± 0.6 ppm, 3.0 ± 0.4 %). Among gneisses, potassic-type gneisses have higher radioelements (11.8 ± 5.3 ppm, 3.1 ± 1.2 ppm, 2.0 ± 0.5 %) than the sodic-type gneisses (5.6 ± 2.8 ppm, 1.3 ± 0.5 ppm, 1.4 ± 0.7 %). Moreover, the pink granitoid and the biotite granitoid have higher Th/U (6 and 8, respectively) compared to the grey granitoid (Th/U: 4), implying enrichment of Th in pink and biotite granitoids relative to grey granitoid. K/U among pink, biotite and grey granitoids shows little variation (0.6 × 104, 0.6 × 104, 0.7 × 104, respectively), indicating relatively similar increase in K and U. Therefore, mineralogical and petrological data along with radioelemental ratios suggest that radioelemental variations in these lithounits are mainly related to abundances of the radioactive minerals that have formed by the fractionation of LILE from different magma sources. Based on present data, the craton can be divided into three distinct zones that can be correlated with its evolution in time and space. The central part, where gneisses are associated with metavolcanics of greenstone belt, is

    WARPE, BM; SHRIKHANDE, AV; POFLEE, SV

    2016-01-01

    Background: Until now, trimodal distribution of HbS has been seen by six different studies in the world when associated with alpha-thalassemia with confirmation by corresponding alpha-genotyping studies. The RBC indices reduce as alpha-globin genes reduce in sickle cell trait (SCT) patients, which decreases the extent of intra-vascular sickling and thus betters the clinical course of the patients. This is a pioneer study conducted on Central Indian poor population to use the already proven six studies to screen associated alpha-thalassemia in SCT patients thus, circumventing the much costlier alpha-genotyping studies. Moreover, it aimed to study the haematological parameters in such cases. Methods: The study was performed at RHDMC, IGGMC, Nagpur, India from 2003 to 2012. The sample population was suspected cases of haemolytic anaemia. CBC and RBC indices were obtained by a cell analyzer. The sickle solubility test positively screened cases were confirmed by agar-gel haemoglobin electrophoresis at pH 8.6. Finally, quantitative assessment of haemoglobin variants was performed by HPLC. Results: Out of total 5819 cases over ten years, 933 cases were sickle heterozygotes. Overall, 180/933 subjects were predicted to be homozygous alpha-thalassemia and 338/933 were heterozygous alpha-thalassemia, based on trimodal distribution of HbS. Conclusion: Genotyping is costlier for majority of the poor non-affording patients in Indian government set-ups, so this study is suitable to screen for associated alpha-thalassemia in SCT patients.

    Kolkata is one of the four major metropolitan cities in India and the capital city of the state of West Bengal. With an area of 187.33 km2 and a population of about 10 million (including a floating population of about 6 million), the city generates about 3500 Metric Ton (MT) of solid waste per day. Currently, Kolkata Municipal Corporation (KMC) disposes its waste at Dhapa (21.47 ha), where the disposal rate exceeds 3000 MT/day, and at Garden Reach (3.52 ha), where the disposal rate is 100 MT/day. Considering the exhaustion of Dhapa land space, city planners are urgently searching for an alternate disposal ground. National Environmental Engineering Research Institute (NEERI), under the sponsorship of Central Pollution Control Board (CPCB), has brought out literature developing the site selection criteria for municipal solid waste disposal ground to suit Indian conditions. The developed criteria encompass environmental conditions, accessibility, geological and hydrogeological conditions, and ecological and societal effects. This paper attempts to locate the most suitable site for disposal of KMC area solid waste using the multicriterion decision analysis as stipulated in CPCB 2003 guidelines and the overlay analysis of geographic information system (GIS). Implications: The paper is based on landfill site selection for dumping of solid waste generated within Kolkata Municipal Corporation (KMC) area. The methodology uses GIS/remote sensing, Site Sensitivity Index (an offshoot of pairwise comparison technique developed in CPCB 2003 guidelines, Government of India), and the Delphi technique. Dhapa landfill site, where solid waste of KMC area is currently being disposed, is exhausted; the authors of this article thus found it relevant to carry out a research on the selection of an alternative landfill site. The study undertaken was comprehensive, yet presented in a lucid way so that policymakers will find easy to comprehend. PMID:25122958

    The beaches are by far the most widely distributed of any of the coastal sedimentary environments. A great many factors are involved in providing sediment for accumulation and development of the beach. The sediment at most places is locally derived, however it can travel and could have traveled long distances shaping the beaches over different season/annual cycles. The granulometric analysis of sediments has long been oriented towards finding environment diagnostic descriptors of grain size distributions (McLaren, 1981) using either the Friedman's (1961, 1967 and 1979) moment method or more commonly the Folk and Ward's (1957) graphic method. It is understood that, the grain size analysis is one of the important tools to delineate littoral drift. The assessment or understanding of this littoral drift and the littoral drift data help to assist in many developmental schemes such as- the harbor development, recreation, tourism development, location of sand traps, growth of coastal bars/spits beach starvation and associated erosion, coastal protection, navigation and so on. In the present study, the sedimnt dynamics of Vengurla-Aravli stretch of beach has been undertaken using the four seasons (Premonsoon, Monsoon & Postmonsoon 2003; and Premonsoon 2004), grain size data alongwith the supporting data on longshore currents and wave parameters collected at 14 study sites. The sediment samples were collected across the beach at every 10 m interval. The study highlights textural variation, sediment movement across and along the beach, energy condition and overall depositional environment of the study area.

    The presence of antisperm antibodies in serum may impair sperm function leading to immunological infertility. The aim of study was to determine the presence of antisperm antibodies in the circulating blood of infertile couples. This cross sectional study included 109 couples suffering from infertility for more than one-year duration. Serum antisperm antibodies were determined by Varelisa Sperm Antibodies Enzyme Immunoassay kit. The percentage incidence of antisperm antibodies in infertile men was 30.27% was statistically not significant from the 33.03% incidence in infertile women (P Value > 0.05). In the nineteen (15.59%) couples both the husband as well as wife was positive for sperm antibodies. The presence of antisperm antibodies may impair fertilizing ability therefore its assessment should be consideredas an essential part of infertility management. PMID:23734441

    Background and objectives: Tribal men's reluctance in sharing responsibilities as supportive partners in reproductive and sexual health matters debar women from their sexual rights coupled with their negligence in health care and lesser utilization of reproductive health facilities. As a matter of fact a large proportion of ill health particularly related to sexually transmitted infections (STIs) suffered not only by men but also by their spouses. The present study was planned among one of the primitive tribes of Madhya Pradesh to understand the knowledge of males about reproductive tract infection (RTI)/STI/HIV/AIDS, RTI symptoms suffered, perception on sexual health, utilization of health services and to improve the knowledge by intervention of need based IEC (information, education, communication) strategy. Method: The study was conducted among 400 currently married men in the age group of 15-40 yr in one of the primitive tribes, Baigas of Dindori district of Madhya Pradesh. Eighteen villages were explored in the study. The IEC intervention was made by using quasi-experimental before and after with control design. Result: The baseline data generated indicated that Baigas male were poorly informed about RTI (18%), STI (21.5%) and HIV/AIDS (10%). Further, men also projected misconception on different aspects of sexuality. Women's views recorded also suggested a disturbing trend regarding male involvement in reproductive health particularly related to STIs. Interpretation & conclusions: After intervention of IEC targeting male population in age group 15 - 40 yr by adopting a before and after with controls design the awareness was improved significantly. The utilization of the health services was also improved significantly. The study recommends replication of the IEC strategy designed in other Baiga villages for improving the reproductive health of the tribe. PMID:23760379

    This preliminary field study was designed chiefly to test the efficiency of the light-trap as a tool for sampling malaria vectors, in tribal villages located in different ecological settings in comparison with indoor resting collections as an alternative method. Anopheles culicifacies, a known malaria vector, was the most prevalent species in the study villages and more than 80% of trap catches were obtained before midnight with peak activity during dusk. Reproductive status of trapped specimens revealed proportional representations of unfed, freshly fed, and gravid females. Another vector, An. fluviatilis was found in small numbers by both the methods. Thus the trap could give a reliable and unbiased sample of vector population. Seven species were abundant in the light-trap catches while only four in the indoor resting collections indicates the usefulness of the light-trap for sampling exophilic species. The study revealed that light-traps did not have any bias in favor of any particular species. The method may be useful for assessing the night time densities of different species or the fluctuation of a species at different dates and village to village variations. Light-traps could be used for sampling both endophilic and exophilic anophelines. PMID:9322305

    The uranium concentration in groundwater has attained greater importance considering the health effects in mankind. Groundwater being the major source of uranium; sampling and analysis of groundwater for the major cations and anions along with uranium has been carried out in hard rock aquifers of Madurai district. The sampling has been carried out in varied aquifers like, Charnockites, Hornblende Biotite Gneiss, Granites, Quartzites, Laterites and sandstone. The cation and anions showed the following order of dominance Na+>Ca2+>Mg2+>K+ and that of anions are HCO3 ->Cl->SO4 2-> NO3 ->PO4 3-. Higher concentration of uranium was found along the granitic aquifers and it varied along the groundwater table condition. Further it was identified that the mineral weathering was the predominant source of U in groundwater. Tritium studies also reveal the fact that the younger waters are more enriched in uranium than the older groundwater with longer residence time.

    We investigated the associations of mouthguard awareness and use with the rate and type of orofacial trauma during sports activities among professional athletes. In this cross-sectional study of athletes aged 12 to 22 years who trained for participation in national and international competitions, data were collected by using a questionnaire and a clinical examination that included an index of dental injury. There were significant differences in mouthguard awareness and use and injury rates, i.e., athletes who did not wear mouthguards had more injuries. Traumatic injuries to teeth were significantly more frequent among contact athletes (15; 9%) than among noncontact athletes (4; 2.5%). Limited mouthguard awareness could be due to lack of information and education on dental injuries and their prevention. PMID:25500920

    Economic analysis plays a pivotal role in the management of medical store. The main objectives of this study were to consider always better control-vital, essential and desirable (ABC-VED) analysis with economic order quantity (EOQ), comparison of indexed cost and the actual cost, and to assess the expenditure for the forthcoming years. Based on cost and criticality, a matrix of nine groups by combining ABC and VED analysis was formulated. Drug categories were narrowed down for prioritization to direct supervisory monitoring. The subgroups AE and AV of the categories category I and II should be ordered based on EOQ. The difference between the actual annual drug expenditure (ADE) and the derived indexed cost using the cost inflation index (CII) was calculated. Linear regression was used to assess the expenditure for the forth coming years. The total ADE for the financial year of 2010-2011 was Rs. 1,91,44,253 which was only 7.68% of annual hospital expenditure. Using the inflation index, the indexed cost of acquisition of ADE for year 2010-2011 was Rs. 1,95,10,387. The difference between the two was estimated to be 2.11%. Thus, the CII justifies the demand of increased budget for next year and prompts us for cautious use of drugs. By taking into consideration the ADE of last 10 years, we have forecasted the budget for forthcoming years which will help significantly for making policies according to the available budget.

    A systematic study on the seasonal variation of major cations and anions was carried out to understand the source of dissolved ions as well as the geochemical weathering processes controlling the meltwater chemistry of Gangotri glacier. Calcium and magnesium are the major cations while sulphate is the dominant anion followed by bicarbonate. The high ratios of (Ca + Mg)/(Na + K), Ca/Na, Mg/Na, HCO3/Na and low ratio of (Na + K)/TZ+ for pre-monsoon, monsoon and post-monsoon seasons indicate the dominance of carbonate weathering, which is a major source of the dissolved ions in the meltwater of Gangotri glacier followed by silicate weathering. High equivalent ratios of Na/Cl and K/Cl as compared to sea water indicate relatively lesser contribution from atmospheric input to the chemical composition of meltwater. Correlation matrix and factor analysis were used to identify various factors controlling the major ion chemistry. Marked seasonal and diurnal variations were observed in the dissolved ions and suspended sediment concentration. Daily mean suspended sediment concentration for pre-monsoon, monsoon and post-monsoon was observed as 1719, 3281 and 445 mgl-1, respectively. Highest suspended sediment load was observed in monsoon season followed by pre-monsoon and post-monsoon seasons. The cation denudation rates of Gangotri glacier meltwater were calculated to be 42.2, 46.5 and 15.9 t km-2 y-1 for pre-monsoon (June only), monsoon and post-monsoon respectively. These values are higher than that of other Himalayan glaciers. Whereas physical weathering rate of the Gangotri glacier catchment was observed to be 7056, 15,344 and 588 t km-2 y-1 for pre-monsoon (June only), monsoon and post-monsoon respectively, much higher than the Indian and world averages of river.

    Context: There is a lack of evidence on the subjective aspects of the provider perspective regarding diabetes and its complications in India. Objectives: The study was undertaken to understand the providers' perspective on the delivery of health services for diabetes and its complications, specifically the eye complications in India. Settings and Design: Hospitals providing diabetic services in government and private sectors were selected in 11 of the largest cities in India, based on geographical distribution and size. Methods: Fifty-nine semi-structured interviews conducted with physicians providing diabetes care were analyzed all interviews were recorded, transcribed, and translated. Nvivo 10 software was used to code the transcripts. Thematic analysis was conducted to analyze the data. Results: The results are presented as key themes: “Challenges in managing diabetes patients,” “Current patient management practices,” and “Strengthening diabetic retinopathy (DR) services at the health systems level.” Diabetes affects people early across the social classes. Self-management was identified as an important prerequisite in controlling diabetes and its complications. Awareness level of hospital staff on DR was low. Advances in medical technology have an important role in effective management of DR. A team approach is required to provide comprehensive diabetic care. Conclusions: Sight-threatening DR is an impending public health challenge that needs a concerted effort to tackle it. A streamlined, multi-dimensional approach where all the stakeholders cooperate is important to strengthening services dealing with DR in the existing health care setup. PMID:27144138

    The components and quantities of atmospheric dust fallout have been reported to be the pollution indicator of large urban areas. The multiplicity and complexity of sources of atmospheric dusts in urban regions has put forward the need of source apportionment of these sources indicating their contribution to specific environmental receptor. The study presented here is focused on investigation of source contribution estimates of Arsenic in urban dust fallout in an urban-industrial area, Raipur, India. Source-receptor based representative sampling plan using longitudinal study design has been adopted. Six sampling sites have been identified on the basis of land use for development plan of anthropogenic activities and factors related to the transportation and dispersion pattern of atmospheric dusts. Source apportionment has been done using Chemical Mass Balance (CMB 8). Good fit parameters and relative source contribution has been analyzed and documented. Dominance of coal fired industries sources on arsenic levels measured at selected ambient residential receptors compared to line sources has been observed. Road-traffic has shown highest contribution of dust at indoor houses and out door-street automobile exhaust has shows highest contribution for arsenic. The results of CMB output and regression data of source-receptor dust matrices have shown comparable pattern.

However, neurological complications, in general, are unusual but have been observed more frequently in the recent past, and some studies highlighted varied neurological complications during the course of illness. Although dengue is classically considered a nonneurotropic virus, there is increasing evidence for dengue viral neurotropism. In this study, we have evaluated clinico-radiological profile and outcome of nine serologically confirmed dengue patients having varied manifestations of central nervous system (CNS) involvement. Materials and Methods: All the consecutive patients presented with neurological complications with positive serology for dengue infection (IgM positivity) in Department of Medicine, in a tertiary care hospital in Eastern India from August 2013 to October 2014 were included in the study. These patients were subjected to a detailed clinical evaluation, laboratory assessment including complete hemogram, coagulation profile, liver function test, serum electrolytes, and routine CSF (Cerebrospinal Fluid) study with the exclusion of other common neuroinvasive pathogens. Results: Out of 9 patients with neurological complications associated with confirmed dengue infection, 2 (22%) patients had dengue encephalopathy, 5 (56%) patients have dengue encephalitis, 1 (11%) patient had dengue meningitis, and 1 (11%) patient had postdengue immune-mediated CNS involvement. Conclusion: This case series reaffirms the occurrence of varied CNS manifestations in dengue virus infection and underlines the importance of inclusion of dengue in the differential diagnosis of acute encephalitis syndrome.

    Background: There is a lack of information on the practice patterns and available human resources and services for screening for eye complications among persons with diabetes in India. Objectives: The study was undertaken to document existing health care infrastructure and practice patterns for managing diabetes and screening for eye complications. Methods: This cross-sectional, hospital-based survey was conducted in 11 cities where public and private diabetic care providers were identified. Both multispecialty and standalone diabetic care facilities were included. A semi-structured questionnaire was administered to senior representative(s) of each institution to evaluate parameters using the World Health Organization health systems framework. Results: We interviewed physicians in 73 hospitals (61.6% multispecialty hospitals; 38.4% standalone clinics). Less than a third reported having skilled personnel for direct ophthalmoscopy. About 74% had provision for glycated hemoglobin testing. Only a third had adequate vision charts. Printed protocols on management of diabetes were available only in 31.5% of the facilities. Only one in four facilities had a system for tracking diabetics. Half the facilities reported having access to records from the treating ophthalmologists. Direct observation of the services provided showed that reported figures in relation to availability of patient support services were overestimated by around 10%. Three fourths of the information sheets and half the glycemia monitoring cards contained information on the eye complications and the need for a regular eye examination. Conclusions: The study highlighted existing gaps in service provision at diabetic care centers in India. PMID:27144131

    Abstract: Background: The Department of Oral and Maxillofacial Surgery, D.A.V [C] Dental College and Hospital, Yamuna Nagar, Haryana, India conducted a study on patients with maxillofacial fractures in a time span of seven years (2003-2010). The purpose of this study was to evaluate their aetiology, incidence, patterns and different modalities employed for management. Methods: In this study, 740 patients with 1054 fractures were evaluated clinically and radiographically, based on which closed reduction and open reduction was undertaken. Review of patient records included: Age, sex, time, mechanism and etiology of injury, history of bleeding, unconsciousness and prior first aid, type of vehicle and use of preventive measures, type of fracture and treatment modalities. Results: Road traffic accidents accounted for highest number of fractures predominantly occurring in the age group of 21-30 years (38.3%)1,2. Males incurred more fractures with a male female ratio of 4.2: 1.Mandible was the most commonly fractured bone with parasymphysis being the commonest affected site.76.66% patients had associated head injury and 15.68 % had history of unconsciousness. Open reduction and internal fixation was the preferred modality for mandible whereas the mid face fractures were treated more often by closed methods. Conclusions: Injuries occurred more commonly in 20 – 40 age range with road traffic accident being the major etiological factor. Majority of the patients were driving two wheelers and most were under the effect of alcohol. Most of the injuries occurred during night and road traffic accidents (71.89%) were found to be the major etiological factor. Out of 532 road traffic accidents, 490 patients (66.2%) were on two wheelers, among whom 49(10%) were wearing helmet. In the mandible, fractures occurred most commonly in the parasymphyseal region (224, 30.2%), and out of the 314 fractures of the middle third showed, 155 (49.4%) ZMC. OPG was the most commonly advised X

    Delhi, the capital of India, is an important metropolitan hub for major financial and sociocultural exchanges, offering challenging threats to current public health infrastructure. In recent past, an upsurge of dengue cases in Delhi posed a significant menace to the existing dengue control policies. To reform the control strategies and take timely intervention to prevent future epidemics, an epidemiological study on the proportion of both asymptomatic and symptomatic dengue infections in selected population was conducted. The aim of the study was to investigate and assess the epidemiology of dengue infection and to estimate the proportion of asymptomatic and symptomatic dengue infections in Delhi. In this study, around 50 confirmed dengue cases, a total of 2125 individuals as household and neighbourhood contacts, with or without dengue febrile illness, were finger pricked and serologically detected as dengue positive or negative using SD Duo Bioline Rapid Diagnostic Test (SD Inc, Korea) with NS1, IgM & IgG combo test, which detected dengue virus antigen and antibodies to dengue virus in human blood. Out of 2125 individuals, 768 (36.1%) individuals showed positive dengue test with past (25.5%), primary (1.88%) or secondary (8.8%) dengue infections. Higher percentage of IgG was found in age groups 15-24 years and 25-50 years (36% each). Infants (<1 year) presented higher incidence of new infections (22% of NS1+IgM positives) as compared to adults. Further analysis revealed that out of the 226 newly infected cases (including NS1 and IgM positives), 142 (63%) were asymptomatic and 84 (37%) were symptomatic, as per WHO guidelines. Our findings also suggest that out of the total population screened, 10.6% dengue infection was either primary or secondary. On the basis of these results, it may be hypothesized that there are large number of asymptomatic dengue infections in the community as compared to reported symptomatic cases in Delhi.

    Central exclusive production of a system X in a collision between two hadrons h is defined as hh {yields} h + X + h with no other activity apart from the decay products of X. This thesis presents predictions for the production cross section of a CP violating supersymmetric Higgs boson and the radion of the Randall-Sundrum model. The ExHuME Monte Carlo generator was written to simulate central exclusive processes and is described and explored. A comparison to di-jet observations made by the D0 detector at the Tevatron, Fermilab between January and June 2004 is made and the distributions found support the predictions of ExHuME.

  16. New Insights into the Structure of the Northern Margin of the India-Asia Collision from Magnetotelluric Data across the Central Altyn Tagh Fault

    The Altyn Tagh Fault (ATF) is a left-lateral, strike-slip fault that forms the northern margin of the Tibetan Plateau and plays a significant role in accommodating the convergence between the colliding Indian and Eurasian plates. As a part of the fourth phase of the INDEPTH project, magnetotelluric (MT) data were collected across the central segment of the ATF to determine the lithospheric-scale structure of the fault system. Dimensionality analyses demonstrated that the MT data can be interpreted using two-dimensional approaches, but some localized 3-D effects are seen. Consequently, both 2-D and 3-D inversions were carried out, and a joint interpretation was made on the basis of these two types of models. Inversion models revealed two major conductors beneath the Qaidam Basin (QB) and Altyn Tagh Range (ATR), respectively. The conductive region beneath the QB was interpreted as a ductile layer in the lower crust to upper mantle that might represent flow beneath the western margin of the QB, whereas the large scale south-dipping conductor beneath the ATR is interpreted as a region with high fluid content formed by metamorphism associated with the oblique underthrusting of the Tarim Block beneath the northern Tibetan Plateau. These fluids migrate upward through the fault system and have formed serpentinized zones in the crust. Combining these interpretations, a structural model compatible with diverse geophysical observations is proposed, in which we suggest the competing end-member rigid block model and continuum model are reconcilable with the continuum model locally dominant for the study region, as evidenced by a thickened crust. * This work was funded by National Natural Science Foundation of China (41404060, 40974058, 40904025) and Fundamental Research Funds for the Central Universities (2652014016).

    Understanding the relationship between women's political participation and health has eluded researchers and cannot be adequately studied using traditional epidemiological or social scientific methodologies. We employed a health capability framework to understand dimensions of health agency to illuminate how local political economies affect health. Exploiting a cluster-randomized controlled trial of a community-based behavior change management intervention in northern India, we conducted a qualitative study with semistructured, in-depth focus groups in both intervention and nonintervention villages. We presented scenarios to each group regarding the limitations and motivations involved in women's political participation and health. Thematic analysis focused on four domains of health agency -- participation, autonomy, self-efficacy, and health systems -- relevant for understanding the relationship between political participation and health. Elder women demonstrated the greatest sense of self-efficacy and as a group cited the largest number of successful health advocacy efforts. Participation in an associated community-based neonatal intervention had varying effects, showing some differences in self-efficacy, but only rare improvements in participation, autonomy, or health system functioning. Better understanding of cultural norms surrounding autonomy, the local infrastructure and health system, and male and female perceptions of political participation and self-efficacy are needed to improve women's health agency. For a community-based participatory health intervention to improve health capability effectively, explicit strategies focused on health agency should be as central as health indicators.

    Methicillin resistant staphylococci (MRS) commonly found in clinical samples or associated environment pose a major health challenge globally. The carriage rate of MRS in human population is high, especially in India but research on airborne distribution of MRS is scanty. The present study aimed to evaluate the prevalence of MRS in indoor and outdoor environment of residential houses. Air samples were collected using impactor air sampler. The total counts of viable bacteria, staphylococci, and MRS along with the particles of various sizes were determined from indoor and outdoor environment of 14 residential houses. MRS bacteria were identified as methicillin resistant S. aureus (MRSA) or coagulase negative staphylococci (CNS) employing biochemical and PCR assays. The average concentration of MRS inside and outside of the houses was 5.9% and 4.6% of the total bacteria, respectively. The maximum correlation of total indoor and outdoor bacteria with particulate matter was 10 μm (r = 0.74) and 5 μm (r = 0.84), respectively. Statistically, significant positive correlation of staphylococci and MRS was found with particles of 10–25 μm inside the houses. Molecular surveillance, antibiotic stewardship programme, and infection control policies can help to manage increasing MRS burden in developing countries. PMID:26925268

    Premise of research A large number of fossil coryphoid palm wood and fruits have been reported from the Deccan Intertrappean beds of India. We document the oldest well-preserved and very rare costapalmate palm leaves and inflorescence like structures from the same horizon. Methodology A number of specimens were collected from Maastrichtian–Danian sediments of the Deccan Intertrappean beds, Ghughua, near Umaria, Dindori District, Madhya Pradesh, India. The specimens are compared with modern and fossil taxa of the family Arecaceae. Pivotal results Sabalites dindoriensis sp. nov. is described based on fossil leaf specimens including basal to apical parts. These are the oldest coryphoid fossil palm leaves from India as well as, at the time of deposition, from the Gondwana- derived continents. Conclusions The fossil record of coryphoid palm leaves presented here and reported from the Eurasian localities suggests that this is the oldest record of coryphoid palm leaves from India and also from the Gondwana- derived continents suggesting that the coryphoid palms were well established and wide spread on both northern and southern hemispheres by the Maastrichtian–Danian. The coryphoid palms probably dispersed into India from Europe via Africa during the latest Cretaceous long before the Indian Plate collided with the Eurasian Plate. PMID:25394208

    The characteristics of internal tides (ITs) and near-inertial waves (NIWs) on the continental shelf and slope off Jaigarh (17∘N), central west coast of India were studied. Eight-month (March-October) long Acoustic Doppler Current Profiler (ADCP) measurements made in the year 2008 were used in the present study. Analysis of sea surface heights from satellite altimeter data, where the tracks of the satellites are oriented nearly in the direction of the semimajor axis of barotropic tides, reveals the presence of diurnal and semidiurnal internal tides with surface amplitudes of about 2 cm. Baroclinic current spectra of horizontal velocities show peaks in IT frequencies of M2, S2, K1 and O1 and in inertial frequency (f). The observed current spectra show higher energies than those in Garrett-Munk reference spectra by about 2-3 times. Based on the estimates of "critical topography" (where the topographic slope is equal to the slope of IT) and computed barotropic body force (Baines, 1982), the shelf-edge, mid-slope and deep part of the slope region are found to be the possible generation sites of internal tides in the region. Over the period of observation, the IT on the slope is found to be energetic, with a strong IT during March to mid-April (pre-monsoon period). Whereas, on the shelf, IT is weak during the pre-monsoon and found to be strong in the southwest monsoon. The available hydrographic data and model simulated hydrography suggest that this difference is linked with the stratification changes on the shelf and slope during these seasons, where the stratification is found to be weak on the shelf and strong on the slope during pre-monsoon. Strong low-mode NIW is observed on the shelf associated with the storm events while the NIW is found to be less energetic on the slope.

    Cloud characteristics over the rain-shadow region of the north central peninsular India has been studied using C-band radar data for the period 21 September-30 October 2011. The period covers withdrawal and post-withdrawal periods of monsoon 2011. Though the study has been carried out for one season, it has been shown that it is representative of climatic feature over the region. The cloud characteristics have been discussed in the context of large scale dynamical and thermodynamical conditions over the region using NCEP wind data and radiosonde data, respectively. The large scale dynamic and thermodynamical conditions were found favorable for occurrence of widespread and deep convection. The cloud top heights show tri-modal distribution with peaks at 2-3, 4-6 and 8-12 km which are associated with cumulus, congestus and cumulonimbus clouds, respectively. The tops of these three types of the clouds are found to be associated with the stable layers in the atmosphere. The frequency of congestus clouds was the highest. The cloud characteristics over the region differ from other tropical land and oceanic regions in respect of maximum height, mean duration and cumulative frequency distribution. Distribution of cloud top height and duration show deviation from lognormality in the lower ends. It indicates that the cloud growth mechanism is different than that observed over other tropical land and oceanic regions and also due to the large wind shear prevailed over the region. During the period, a large number of suitable clouds were found available for hygroscopic and glaciogenic cloud seeding.

    Context: To explore genotoxicity in bidi rollers occupationally exposed to bidi tobacco dust. Aims: To assess the extent of genotoxicity of tobacco dust to bidi rollers of Jabalpur, Madhya Pradesh, India and cytotoxicity of bidi tobacco extract. Settings and Design: Blood samples from 31 bidi rollers and 30 controls taken after written informed consent were analyzed for chromosome aberrations (CA) and comet assay. Materials and Methods: Genotoxicity was studied by CA in cultured peripheral blood lymphocytes of bidi rollers and the deoxyribonucleic acid (DNA) damage studies were done by comet assay of their blood. The toxicity of bidi tobacco extract to normal human lymphocytes was studied by MMT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay as drop in viability. Statistical Analysis Used: Student's t-test and DMRT. Results: There is a general trend of increase in CA% of both in exposed and control groups with age, but in every group the bidi rollers have a significantly higher CA% than the controls. The CA % is also directly related to exposure. The comet assay findings reveal that the mean comet length and tail length increases with exposure time. The toxicity of bidi tobacco extract (TE) to normal human lymphocytes was tested in vitro by 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay at 2 h of incubation. The trend of drop in viability with increasing concentrations of TE was clearly evident from the data from four donors in spite of their individual differences in viability. Conclusions: The results obtained in this investigation indicate that bidi rollers seem to be facing the occupational hazard of genotoxicity due to handling bidi tobacco and inhalation of tobacco dust. They should be advised to work under well-ventilated conditions. PMID:24748730

    Introduction “The art of medicine is intricately tied to the art of communication.” In traditional medical curriculum, communication is not taught formally and this leads to a gap in reliability and consistency of the teaching. Few studies have shown that much litigation against doctors is due to lack of communication and not because of lack of clinical expertise. Considering the importance of training in communication skills, it was included in the curriculum of students of DMIMS (DU), which has got probably the first communication skills lab in a medical college in India. Aim To study the perception of medical students about usefulness of communication skills lab. Materials and Methods This observational study was carried out at Communication Skills Lab (CSL) of Jawaharlal Nehru Medical College, Sawangi (M), Wardha, Maharasthra. Feedback was obtained with the help of a prevalidated questionnaire from 65 final MBBS students about their perception about utility of the module taught in the CSL including factors which helped and which hindered in learning. Descriptive statistics was used for the quantitative data and categorization for qualitative data. Results A total of 78.46% students were of the idea that CSL posting is must for all medical undergraduates. A 93.83% perceive that the module taught was very relevant and useful and were satisfied with the duration of posting (81.47%). A 78.46% students experienced improvement in their communication skills. They opined that more emphasis should be given on communication between doctor and patient (61.53%). Conclusion The students found communication skills lab very useful. They desired more emphasis on communication between doctor and patient and sought more interactivity, video demonstrations to be part of the module. PMID:26816918

    When central governments decentralize natural resource management (NRM), they often retain an interest in the local efforts and provide funding for them. Such outside investments can serve an important role in moving community-based efforts forward. At the same time, they can represent risks to the community if government resources are not stable over time. Our focus in this article is on the effects of withdrawal of government resources from community-based NRM. A critical question is how to build institutional capacity to carry on when the government funding runs out. This study compares institutional survival and coping strategies used by community-based project organizations in two different contexts, India and the United States. Despite higher links to livelihoods, community participation, and private benefits, efforts in the Indian cases exhibited lower survival rates than did those in the U.S. cases. Successful coping strategies in the U.S. context often involved tapping into existing institutions and resources. In the Indian context, successful coping strategies often involved building broad community support for the projects and creatively finding additional funding sources. On the other hand, the lack of local community interest, due to the top-down development approach and sometimes narrow benefit distribution, often challenged organizational survival and project maintenance.

    Background: While western studies have focused on the importance of psychiatric illnesses in the complex pathways leading to suicides, several Indian studies have highlighted the important contributions by economic, social, and cultural factors. Hence, we tested the hypothesis that annual national suicide rates and suicide rates of the different states in India were associated with macroeconomic indices. Materials and Methods: Data from the National crime records bureau, Ministry of finance, labour bureau, Government of India, population commission, and planning commission official portals, World Bank and the United Nations were accessed. We assessed the correlations of annual national and state-wise suicide rates with macroeconomic, health, and other indices using ecological study design for India, and for its different states and union territories. Results: We documented statistically significant associations between the suicide rates and per capita gross domestic product, consumer price index, foreign exchange, trade balance, total health expenditure as well as literacy rates. Conclusions: As recent economic growth in India is associated with increasing suicide rates, macroeconomic policies emphasizing equitable distribution of resources may help curtailing the population suicide rates in India.

    The experiences of sexual minority women (i.e., women who do not identify as 'heterosexual') in India have largely been absent in scientific literature. In partnership with India's oldest and largest sexual and gender minority-advocacy organisation, the Humsafar Trust, our study used community-based participatory research principles to explore the lived experiences and health concerns of sexual minority women in Mumbai. Study methodologies included interviews with key informants, a focus group comprised of six women, and an additional 12 in-person interviews with sexual minority women to identify important physical, mental, social and other health priorities from these women's perspectives. Thematic data are organised within the framework offered by the social ecological model, including individual, interpersonal, micro and macro levels. Findings from this study are important in providing the groundwork for future research and intervention involving sexual minority women in India, a dramatically underserved population. PMID:26873141

    India is in the middle of the epidemiological transition, with the burden of disease shifting towards chronic conditions, of which cardiovascular diseases (CVDs) form a major part. Findings from the Framingham Heart Study (FHS) have tremendous potential to circumvent the projected increase in CVD burden in India, as they highlight the importance of measuring risk in individuals and populations, and preventing future onset of disease. The findings of the FHS have stimulated several cross-sectional studies in India documenting a high and increasing burden of CVD risk factors. These have led to policy level changes in the country, in the form of Framework Convention on Tobacco Control ratification, and the National Program on Diabetes, CVD, and Stroke. There is now need for an Indian cohort study on the lines of the FHS, which can more closely evaluate the use of the FHS risk score among Indians and translate FHS findings into the Indian context.

    As per the United Nations 2013 report, India's population is expected to reach 1.2 billion by 2015. Thus, there is a need for professionals trained in demography and population studies to carry out research regarding population aspects and project population growth/trends. This study landscapes the academic courses being offered in demography and population studies in India (in regular and distance learning modes). It outlines the details of these courses with respect to available courses, fee structure, number of seats, eligibility criteria, duration, nature of the program, etc. The details of the institutes offering demography and population studies courses were collected and compiled. A systematic and predefined approach including Internet search, search in the leading newspapers and discussions with students, academicians, and faculties were used to collect information for different courses provided by institutes all over India. There are around 22 institutions currently offering certificate, diploma, Masters, Master of Philosophy (M.Phil), and doctoral courses in demography and population studies in India (through regular and distance learning modes). Based on the annual intake capacity of these academic institutions, around 1,052 qualified professionals are available to work in the field of demography and population studies in India. This work has helped us to identify and track various academic courses being offered in demography and population studies in India. However, the courses that are being offered are relatively small in number when compared with the number of demographers/population scientists required. A need was also felt to include demography at the Bachelor's degree level. PMID:26354393

    This paper reports the occurrence of Tsumoite (a bismuth telluride) in the Heti Cu-Ni-PGM prospect, Gondpipri mafic-ultramafic complex, Central India. The Gondpipri complex consists of several tectonically dismembered gabbronorite-gabbro-anorthositic gabbro — olivine gabbro -websterite disposed in ˜10 km long tonalite-trondhjemitegranodiorite (TTG) and charnockite-enderbite suite of rocks. The mineralization occurs in the sulphide zone hosted by gabbro variants. The host rocks have been deformed and metamorphosed to granulite grade and subjected to various degrees of hydrothermal alteration. The mineralization comprises chalcopyrite, pentlandite, pyrrhotite, cubanite, millerite, and pyrite. In addition to these, occur (1) tsumoite (2) PGM in the form of moncheite, merenskyite, Pd-mellonite, and Pt-Pd-Te-Bi-Fe-S alloy. The present study indicates that the mineralization occurs in two stages related to: (i) magmatic and (ii) hydrothermal remobilization and transport of Cu-rich sulphides, tsumoite and PGM, and their re-deposition in hydrosilicate alteration zones. It is possible that the mineralization at Heti formed at different stages of bismuth activity under variable fS2, T, and fTe2 conditions due to change in total concentration of Te and S and /or cooling. Since the role of S is limited, Te and cooling are important factor influencing mineralogy and composition of tsumoite and associated mineralization. Mineralization occurs in two different modes of occurrences. The early mineralisation occur as blebs, specks and dissemination of sulphides, viz. pyrrhotite, chalcopyrite, pentlandite and minor pyrite ± PGM, whereas later mineralisation occur as stringers, minor veins of sulphides viz. pyrite, millerite, cubanite, sijenite, tsumoite and ± PGM. Mineral assemblages and textural relationships at Heti has indicated precipitation of tsumoite and associated PGM along fractures and secondary silicates, which confirms their hydrothermal origin.

  13. Stable and radioactive carbon in forest soils of Chhattisgarh, Central India: Implications for tropical soil carbon dynamics and stable carbon isotope evolution

    Soils from two sites viz. Kotumsar and Tirathgarh, located ∼5 km apart in a tropical reserve forest (18°52‧N, 81°56‧E) in central India, have been explored for soil organic carbon (SOC) content, its mean residence time (MRT) and the evolution of stable carbon isotopic composition (δ13C). SOC stocks in the upper 30 cm of soil layers are ∼5.3 kg/m2 and ∼3.0 kg/m2; in the upper 110 m are ∼10.7 kg/m2 and ∼7.8 kg/m2 at Kotumsar and Tirathgarh, respectively. SOC decreases with increasing depth. Bomb carbon signature is observed in the upper ∼10 cm. Organic matters in the top soil layers (0-10 cm) have MRTs of the order of a century which increases gradually with depths, reaching 3500-5000 yrs at ∼100 cm. δ13C values of SOC increase with depth, the carbon isotopic fractionation is obtained to be -1.2‰ and -3‰ for soils at Kotumsar and Tirathgarh, respectively, confirmed using Rayleigh isotopic fractionation model. The evolution of δ13C in soils was also studied using a modified Rayleigh fractionation model incorporating a continuous input into the reservoir: the depth profiles of δ13C for SOC show that the input organic matter from surface into the deeper soil layers is either insignificant or highly labile and decomposes quite fast in the top layers, thus making little contribution to the residual biomasses of the deeper layers. This is an attempt to understand the distillation processes that take place in SOC, assess the extent of decomposition by microbes and effect of percolation of fresh organic matter into dipper soil layers which are important for stable isotope based paleoclimate and paleovegetation reconstruction and understanding the dynamics of organic carbon in soils.

    Supervised field trials were conducted at four different agro-climatic locations of India to evaluate the dissipation pattern and risk assessment of spiromesifen on tomato. Spiromesifen 240 SC was sprayed on tomato at 150 and 300 g a.i. ha(-1). Samples of tomato fruits were drawn at 0, 1, 3, 5, 7, 10 and 15 days after treatment and soil at 15 days after treatment. Quantification of residues was done on gas chromatograph-mass spectrophotometer in selective ion monitoring mode in the mass range of 271-274 (m/z). The limit of quantification of the method was found to be 0.05 mg kg(-1), while the limit of determination was 0.015 mg kg(-1). Residues were found below the LOQ of 0.05 mg kg(-1) in 10 days at both the doses of application at all the locations. Spiromesifen dissipated with a half-life of 0.93-1.38 days at the recommended rate of application and 1.04-1.34 days at the double the rate of application. Residues of spiromesifen in soil were detectable level (<0.05 mg kg(-1)) after 15 days of treatment. A preharvest interval (PHI) of 1 day has been recommended on tomato on the basis of data generated under All India Network Project on Pesticide Residues. Spiromesifen 240 SC has been registered for its use on tomato by Central Insecticide Board and Registration Committee, Ministry of Agriculture, Government of India. The maximum residue limit (MRL) of spiromesifen on tomato has been fixed by Food Safety Standard Authority of India, Ministry of Health and Family Welfare, Government of India as 0.3 μg/g after its risk assessment.

    Subduction of buoyant continental lithosphere is one of the least understood plate-tectonic processes. Yet under the Pamir-Hindu Kush, at the northwestern margin of the India-Asia collision zone, unusual deep earthquakes and seismic velocity anomalies suggest subduction of Asian and Indian lithosphere. Here, we report new precise earthquake hypocenters, detailed tomographic images and earthquake source mechanisms, which allow distinguishing a narrow sliver of Indian lithosphere beneath the deepest Hindu Kush earthquakes and a broad, arcuate slab of Asian lithosphere beneath the Pamir. We suggest that this double subduction zone arises by contrasting modes of convergence under the Pamir and Hindu Kush, imposed by the different mechanical properties of the three types of lithosphere involved. While the buoyant northwestern salient of Cratonic India bulldozes into Cratonic Asia, forcing delamination and rollback of its lithosphere, India's thinned western continental margin separates from Cratonic India and subducts beneath Asia. This torn-off narrow plate sliver forms a prominent high-velocity anomaly down to the mantle transition zone. Our images show that its uppermost section is thinned or already severed and that intermediate depth earthquakes cluster at the neck connecting it to the deeper slab, providing a rare glimpse at the ephemeral process of slab break-off.

    Garnet enables constraints on all parameters relevant to lithosphere studies: pressure, temperature, strain, and time. This aspect, in combination with its widespread occurrence in metamorphic rocks, make the mineral a prime target in research into the dynamics of mountain belts. Our ability to obtain and interpret precise age constraints from garnet Lu-Hf and Sm-Nd data has greatly improved over the years. This contribution highlights recent enhancements in garnet geochronology and demonstrates the versatility of this method in two case studies set in the India-Asia collision zone. To enable a more effective use of garnet geochronology, we investigated the retentiveness of Lu-Hf and Sm-Nd isotope signatures in naturally metamorphosed garnet. A grain-size dependent Lu-Hf and Sm-Nd analysis of garnet was done on a sample of a slowly cooled Archean granulite from the Pikwitonei Granulite Domain, Canada. Comparison of the apparent ages to the known thermal history of this rock allowed constraints on chronometer systematics at high temperature. Diffusive re-equilibration is shown to occur to a small (Sm-Nd) to minor, if not insignificant (Lu-Hf), extent during high temperature metamorphism, thus firmly establishing the Lu-Hf and Sm-Nd chronometers as reliable, well-characterized dating tools. Garnet Lu-Hf chronology was done to show that mid-crustal flow and 'Barrovian-type' metamorphism of rocks now exposed in the North Himalayan Gneiss Domes in Central Tibet commenced in the early Eocene. This result is the first to confirm that crustal thickening and contraction in the Tibetan Himalaya was broadly synchronous with the collision between Greater India and Eurasia. Garnet dating and thermometry, and rutile U-Pb thermochronology on granulites from the Pamir (an exposed segment of deep Asia) revealed a history of heating to 750-830 °C, commencing at 37 Ma in the South Pamir and occurring progressively later northward. The data advocate a causal link between Indian slab

    Background: There is a paucity of information on the availability of services for diagnosis and management of diabetic retinopathy (DR) in India. Objectives: The study was undertaken to document existing healthcare infrastructure and practice patterns for managing DR. Methods: This cross-sectional study was conducted in 11 cities and included public and private eye care providers. Both multispecialty and stand-alone eye care facilities were included. Information was collected on the processes used in all steps of the program, from how diabetics were identified for screening through to policies about follow-up after treatment by administering a semistructured questionnaire and by using observational checklists. Results: A total of 86 eye units were included (31.4% multispecialty hospitals; 68.6% stand-alone clinics). The availability of a dedicated retina unit was reported by 68.6% (59) facilities. The mean number of outpatient consultations per year was 45,909 per responding facility, with nearly half being new registrations. A mean of 631 persons with sight-threatening-DR (ST-DR) were registered per year per facility. The commonest treatment for ST-DR was laser photocoagulation. Only 58% of the facilities reported having a full-time retina specialist on their rolls. More than half the eye care facilities (47; 54.6%) reported that their ophthalmologists would like further training in retina. Half (51.6%) of the facilities stated that they needed laser or surgical equipment. About 46.5% of the hospitals had a system to track patients needing treatment or for follow-up. Conclusions: The study highlighted existing gaps in service provision at eye care facilities in India. PMID:27144134

    Rao, Sheldon; Ramesh, Naveen

    2015-01-01

    Background: Mental health disorders affect around 500 million people worldwide. In India, around 10–12% of people are affected by a mental disorder either due to stress, depression, anxiety, or any other cause. Mental health of workers affects the productivity of the workplace, with estimates putting these losses to be over 100 million dollars annually. Aims: The study aims to measure depression, anxiety, and stress levels of workers in an industry and to investigate if it has any effect on productivity of the firm. Materials and Methods: The study utilized a cross-sectional design and was conducted among workmen of the firm. A sociodemographic based questionnaire and a mental health screening tool -Depression Anxiety Stress Scale (DASS)-21 were used for the same. A total of 90 completed questionnaires were analyzed for the study. The data was analyzed for central tendencies as well as for any associations and correlations. Results: The study showed that none of the workers had a positive score for depression. It also showed that around 36% of the workers had a positive score for anxiety and 18% of the workers had a positive score for stress on DASS-21 scale. The odds ratio between stress and number of leaves taken by a worker in the last 3 months suggested a dose–response relationship, but was statistically insignificant. Conclusion: The study found a prevalence rate of around 18–36% for anxiety and stress amongst the workers at the factory. Large-scale studies will help understand the effect mental health status has on the Indian workplace. PMID:26257479

    Men who have sex with men are a hidden population in India. This study explores the psychological violence such men are exposed to in Puducherry, India. Eleven in-depth interviews probe experiences of blackmail, discrimination, and rejection. Some informants modified their behaviors or appearances to avoid harassment and safeguard their families' reputations. Others told how Indian men accepted their behaviors, but rejected their identities. Social pressure to marry was also a recurring theme. Understanding the factors behind these violent experiences may facilitate their amelioration. PMID:24147588

    Soil moisture is the source of water for evapotranspiration over the continents and it participates in both energy and water balance of the earth. Soil moisture participates in the energy cycle by managing the partitioning of the energy budget into latent and sensible heat, there by influencing the hydrological cycle. But to better understand the influence of soil moisture on the hydrological cycle, large scale monitoring is required. The objective of this study is to qualitatively analyze the active-passive merged soil moisture distribution, prepared under the ESA_CCI programme, against two AMSR-E soil moisture distributions, AMSR-E/NSIDC (National Snow and Ice Data Center) and AMSR-E/VUA(Virje Universiet Amstradam) and GLDAS_NOAH model simulations. The ESA_CCI soil moisture distribution is also compared with the GPCC monthly precipitation distribution to observe the representativeness of the precipitation seasonality in the satellite retrieved soil moisture. India has been selected as the study area, esp. the Central Indian region, as it has shown to be a soil moisture hot-spot for land-surface atmosphere interaction. The preliminary study show that both ESA_CCI and AMSR-E/VUA soil moisture distributions capture similar seasonal patterns in addition to processes like rainfall events and inter-annual variations. In addition to this it was also observed that the soil moisture distribution of ESA_CCI and AMSR-E/VUA are linearly related to each other for more than 50% of the land points. In case of ESA_CCI and AMSR-E/NSIDC, the soil moisture distributions are able to capture similar seasonal patterns but not the random events and they also do not show a strong linear relationship. We also analyze the effect of topography and vegetation distribution on the error charactristics of the satellite retrieved soil moisture distributions.

    A better understanding of the past variations of the Indian Monsoon system, which has a deep societal impact on the subcontinent, is essential to determine its behavior under a changing global climate. We aim to reconstruct the variability of the Indian Monsoon, which has both spatially as well as temporally variable nature, during the last 10,000 years using lipid biomarker abundances and stable isotopes from continuous, high-resolution lake sediments in a climatically sensitive region of Central India. Previous sedimentological and geochemical studies on bulk material from a well dated long lake sediment core covering the last 11,000 years have already shown evidence of rapid changes in lithology, sedimentation rate, paleo lake productivity and supply of terrestrial organic matter. Changes in the abundance of source-specific organic compounds - lipid biomarkers - can be useful for the interpretation of past changes in hydrology and ecosystem of the lake and its catchment area as well as their relation to climatic factors. We have identified a number of suitable biomarker compounds for paleohydrological and environmental reconstruction from surface sediments and short cores. Identified biomarker compounds include both aquatic and terrestrial biomarkers. Among the aquatic biomarkers short chain n-alkanes and phytane, most probably derived from cyanobacteria and microbial biomarkers like moretene, diploptene and other hopenes were present. Additionally long chain n-alkanes from vascular land plants from the lake catchment area were identified. Interestingly, the triterpene lipid tetrahymanol and tetrahymanone was found to be the biomarker of highest concentration in all analyzed surface sediments, with concentrations higher than the ubiquitous short-chain fatty acids. Tetrahymanol is often attributed to certain protozoa and frequently found in hypersaline lakes. However, studies have shown that this lipid can also be found in sizable amounts in phototrophic bacteria

    Background This study was undertaken in two Primary Health Centers (PHCs) of malaria endemic district Jabalpur in Madhya Pradesh (Central India). Methods In this study we had investigated the relative frequencies of the different anopheline species collected within the study areas by using indoor resting catches, CDC light trap and human landing methods. Sibling species of malaria vectors were identified by cytogenetic and molecular techniques. The role of each vector and its sibling species in the transmission of the different Plasmodium species was ascertained by using sporozoite ELISA. Results A total of 52,857 specimens comprising of 17 anopheline species were collected by three different methods (39,964 by indoor resting collections, 1059 by human landing and 11,834 by CDC light trap). Anopheles culicifacies was most predominant species in all collections (55, 71 and 32% in indoor resting, human landing and light trap collections respectively) followed by An. subpictus and An. annularis. All five sibling species of An. culicifacies viz. species A, B, C, D and E were found while only species T and S of An. fluviatilis were collected. The overall sporozoite rate in An. culicifacies and An. fluviatilis were 0.42% (0.25% for P. falciparum and 0.17% for P. vivax) and 0.90% (0.45% for P. falciparum and 0.45% for P. vivax) respectively. An. culicifacies and An. fluviatilis were found harbouring both P. vivax variants VK-210 and VK-247, and P. falciparum. An. culicifacies sibling species C and D were incriminated as vectors during most part of the year while sibling species T of An. fluviatilis was identified as potential vector in monsoon and post monsoon season. Conclusions An. culicifacies species C (59%) was the most abundant species followed by An. culicifacies D (24%), B (8.7%), E (6.7%) and A (1.5%). Among An. fluviatilis sibling species, species T was common (99%) and only few specimens of S were found. Our study provides crucial information on the prevalence

    As the population of older adults in India grows, research is needed to plan a sustainable future for India's older adults. This article reports results from a Global Positioning System (GPS)-based pilot study that examined the mobility of middle-class, older adults living in Ahmedabad, Gujarat, India. Using mobility as a lens through which to examine the lives of older adults, we map potential research and identify policy areas of interest considering older adults in urban India. The study explores the role of life stage in mobility as well as the effects of gender and urban environment on mobility. Using this distinctive perspective on day-to-day life, we propose themes through which, using policy and planning tools, the living environments of older adults in Indian cities can be improved. These policy measures include focusing on walkability and pedestrian safety in residential areas and building on existing mixed land use to create high accessibility to goods and services in urban environments.

    Abstract Background In this edge, medical tourism is not a new idea. Medical treatment is one of the essential demands of human beings and it requires high quality and intensive care. Beside western world, few developing countries are playing key roles as medical tourism destinations. India is one of the leading names among these countries. The purpose of the paper is to find the factors influencing the attractiveness of India as a health tourism destination. Methods The study has found the major contributing factors and their relative importance in the attractiveness of the health tourism destination that is India from consumers’ perspectives by conducting survey with an application of structural equation modelling approach. Results In Indian context, medical tourists consider service quality and cost mostly to select any medical destination. In addition they also give value to the destination competitiveness but tourist attitude is less important in comparison with other factors affecting their destination choice. Since the study has used structural equation modelling approach to test the hypothesis and figure out the relative importance of the factors, the fundamental indices such as Normed Chi square(less than 3), RMSEA (less than 0.08) and CFI (more than 0.90) values show the overall model fit of the proposed model. Conclusion In order to transform a country such as India as an attractive and competitive medical tourist destination in this time of globalization, a step should be taken to control cost ensuring the quality of services.

    Prediction of Indian summer (June-September) rainfall on regional scales remains an open issue. The operational predictions of West Central Indian summer rainfall (WCI-R) and Peninsular Indian summer rainfall (PI-R) made by the Indian Meteorological Department (IMD) had no skills during 2004-2012. This motivates the present study aiming at better understanding the predictability sources and physical processes governing summer rainfall variability over these two regions. Analysis of 133 year data reveal that although the lower boundary forcing that associated with enhanced WCI-R and PI-R featured a similar developing La-Nina and "east high west low" sea-level pressure (SLP) dipole pattern across the Indo-Pacific, the anomalous high sea surface temperature (SST) over the northern Indian Ocean and weak low pressure over northern Asia tended to enhance PI-R but reduce WCI-R. Based on our understanding of physical linkages with the predictands, we selected four and two causative predictors for predictions of the WCI-R and PI-R, respectively. The intensified summer WCI-R is preceded by (a) Indian Ocean zonal dipole-like SST tendency (west-warming and east-cooling), (b) tropical Pacific zonal dipole SST tendency (west-warming and east-cooling), (c) central Pacific meridional dipole SST tendency (north-cooling and south-warming), and (d) decreasing SLP tendency over northern Asia in the previous season. The enhanced PI-R was lead by the central-eastern Pacific cooling and 2-m temperature cooling tendency east of Lake Balkhash in the previous seasons. These causative processes linking the predictors and WCI-R and PI-R are supported by ensemble numerical experiments using a coupled climate model. For the period of 1871-2012, the physics-based empirical (P-E) prediction models built on these predictors result in cross-validated forecast temporal correlation coefficient skills of 0.55 and 0.47 for WCI-R and PI-R, respectively. The independent forecast skill is significantly

    PM2.5 mass and its optical properties were measured over an ecologically sensitive zone in Central India between January and December, 2012. Meteorological parameters including temperature, relative humidity, wind speed, wind direction, and barometric pressure were also monitored. During the study period, the PM2.5 (fine PM) concentration ranged between 3.2μgm(-3) and 193.9μgm(-3) with a median concentration of 31.4μgm(-3). The attenuation coefficients, βATN at 370nm, 550nm, and 880nm had median values of 104.5Mm(-1), 79.2Mm(-1), and 59.8Mm(-1), respectively. Further, the dry scattering coefficient, βSCAT at 550nm had a median value of 17.1Mm(-1) while the absorption coefficient βABS at 550nm had a median value of 61.2Mm(-1). The relationship between fine PM mass and attenuation coefficients showed pronounced seasonality. Scattering, absorption, and attenuation coefficient at different wavelengths were all well correlated with fine PM mass only during the post-monsoon season (October, November, and December). The highest correlation (r(2)=0.81) was between fine PM mass and βSCAT at 550nm during post-monsoon season. During this season, the mass scattering efficiency (σSCAT) was 1.44m(2)g(-1). Thus, monitoring optical properties all year round, as a surrogate for fine PM mass was found unsuitable for the study location. In order to assess the relationships between fine PM mass and its optical properties and meteorological parameters, multiple linear regression (MLR) models were fitted for each season, with fine PM mass as the dependent variable. Such a model fitted for the post-monsoon season explained over 88% of the variability in fine PM mass. However, the MLR models were able to explain only 31 and 32% of the variability in fine PM during pre-monsoon (March, April, and May) and monsoon (June, July, August, and September) seasons, respectively. During the winter (January and February) season, the MLR model explained 54% of the PM2.5 variability. PMID

    Central America is the second-most consistently active volcanic zone on Earth, after Indonesia. Centuries of volcanic activity have produced a spectacular landscape of collapsed calderas, debris flows, and thick blankets of pyroclastic materials. Volcanic activity dominates the history, culture, and daily life of Central American countries.January 2002 marked the third consecutive year in which a diverse group of volcanologists and geophysicists conducted focused field studies in Central America. This type of multi-institutional collaboration reflects the growing involvement of a number of U.S. and non-U.S. universities, and of other organizations, in Guatemala and El Salvador (Table 1).

    In India, “non-notified” slums are not officially recognized by city governments; they suffer from insecure tenure and poorer access to basic services than “notified” (government-recognized) slums. We conducted a study in a non-notified slum of about 12,000 people in Mumbai to determine the prevalence of individuals at high risk for having a common mental disorder (i.e., depression and anxiety), to ascertain the impact of mental health on the burden of functional impairment, and to assess the influence of the slum environment on mental health. We gathered qualitative data (six focus group discussions and 40 individual interviews in July-November 2011), with purposively sampled participants, and quantitative data (521 structured surveys in February 2012), with respondents selected using community-level random sampling. For the surveys, we administered the General Health Questionnaire-12 (GHQ) to screen for common mental disorders (CMDs), the WHO Disability Assessment Schedule 2.0 (WHO DAS) to screen for functional impairment, and a slum adversity questionnaire, which we used to create a composite Slum Adversity Index (SAI) score. Twenty-three percent of individuals have a GHQ score ≥5, suggesting they are at high risk for having a CMD. Psychological distress is a major contributor to the slum’s overall burden of functional impairment. In a multivariable logistic regression model, household income, poverty-related factors, and the SAI score all have strong independent associations with CMD risk. The qualitative findings suggest that non-notified status plays a central role in creating psychological distress—by creating and exacerbating deprivations that serve as sources of stress, by placing slum residents in an inherently antagonistic relationship with the government through the criminalization of basic needs, and by shaping a community identity built on a feeling of social exclusion from the rest of the city.

    Background and Aim: Animal chlamydiosis, caused by different chlamydial species, is characterized by clinical or subclinical disease manifestations in cattle, buffalo, ovine, caprine and wild animal species. Animal chlamydiosis often remains underdiagnosed or undiagnosed, and its status in many parts of India is still unknown. Hence, the present study was conducted to determine the seroprevalence of animal chlamydiosis amongst ruminant livestock species of five states of India. Materials and Methods: Totally, 2127 randomly selected serum samples collected from ruminant livestock species viz. cattle (n=430), buffaloes (n=429), sheep (906) and goats (n=362), were tested by agar gel precipitation test for chlamydiosis between 2002 and 2011. Precipitating antigen was prepared from locally isolated strain of Chlamydia psittaci after treatment with sodium deoxycholate. Results: The chlamydial seroprevalence detected amongst ruminants in five states of India was: Himachal Pradesh: Cattle-10.90%, sheep-10.60% and goats- 22.46%; Punjab: Cattle-1.45%; Andhra Pradesh: Cattle-2.80%, buffaloes-0.93%, sheep-8.90% and goats-9.46%; Maharashtra: goats-8.33%; Jammu and Kashmir: sheep-12.50%. The mean seroprevalence values of each animal species are: Cattle-4.65%, buffaloes-0.93%, sheep-9.82% and goats-19.33%. Conclusion: The results indicate the endemic nature of animal chlamydiosis across five states in India. Hence, it requires further extensive studies in other parts of India also using chlamydial species-specific diagnostics to ascertain overall countrywide prevalence of the disease. The zoonotic nature of the chlamydiae of ruminant origin further adds significance to such prevalence studies. PMID:27047000

    2013-01-01

    Background People who originate from the Indian subcontinent (South Asians) suffer among the highest rates of type 2 diabetes in the world. Prior evidence suggests that metabolic risk factors develop early in life and are influenced by maternal and paternal behaviors, the intrauterine environment, and genetic factors. The South Asian Birth Cohort Study (START) will investigate the environmental and genetic basis of adiposity among 750 South Asian offspring recruited from highly divergent environments, namely, rural and urban India and urban Canada. Methods Detailed information on health behaviors including diet and physical activity, and blood samples for metabolic parameters and DNA are collected from pregnant women of South Asian ancestry who are free of significant chronic disease. They also undergo a provocative test to diagnose impaired glucose tolerance and gestational diabetes. At delivery, cord blood and newborn anthropometric indices (i.e. birth weight, length, head circumference and skin fold thickness) are collected. The mother and growing offspring are followed prospectively and information on the growth trajectory, adiposity and health behaviors will be collected annually up to age 3 years. Our aim is to recruit a minimum of 750 mother-infant pairs equally divided between three divergent environments: rural India, urban India, and Canada. Summary The START cohort will increase our understanding of the environmental and genetic determinants of adiposity and related metabolic abnormalities among South Asians living in India and Canada.

    Silicosis from secondary exposure is not often reported. This is the first such report of a child with possible silicosis attributable to secondary exposure to sandstone mining in India. Silicosis from secondary exposure has been reported in the gem polishing and slate pencil manufacturing industries in India; however, the stone-mining industry is severely under-researched. No preventive measures have been instituted in the stone-mining industry and children are exposed to respirable silica dust when their mothers take them to their work places. Poverty and lack of accessibility to modern medical facilities promote malnutrition and tuberculosis, two known co-morbid conditions. Stone mining, an export-oriented industry, produces billions of dollars of foreign currency every year. Although there is legislation to protect workers from exploitation, employers disregard the law and the state turns a blind eye by not implementing proper enforcement mechanisms. Silicosis from environmental exposure affects the entire community that lives in stone-mining areas. PMID:26106174

    Aim: The aim of this study is to ascertain the prevalence of diabetic retinopathy (DR) in diabetic patients across the nation and attempt to establish history-based risk factors. Materials and Methods: A cross-sectional study of diabetic patients was conducted as an initiative of the All India Ophthalmological Society from 14th November to 21st November 2014. Known diabetics were evaluated voluntarily by members of the society at 194 centers using a structured protocol provided by the society for examination. The results were evaluated to ascertain the prevalence of DR in the population studied and to establish relation with gender, age, and history-based risk factors such as duration of diabetes, insulin use, and other end-organ disease using the Chi-square test. Results: A total of 6218 known diabetics were screened. Totally, 5130 data entry forms were considered suitable for further evaluation. About 61.2% were males, 88.6% were between 40 and 80 years of age, almost two-thirds of the patients were from the west and south zones, and over half had diabetes more than 5 years. The data set was predominantly urban 84.7% and 46.1% had no family history. DR prevalence in the entire data set was 21.7%. Prevalence was more in males (P = 0.007), diabetics more than 5 years (P = 0.001), those above 40 years (P = 0.01), insulin users (P = 0.001), and history of vascular accidents (P = 0.0014). Significantly 22.18% of patients detected with DR had a vision of 6/18 or better in the worse eye. Conclusion: The study reiterated the findings of earlier regional studies on a pan Indian scale and put data in perspective. PMID:26953022

    Ages of some key stratigraphic sequences in central Indian Proterozoic basins are based predominantly on lithostratigraphic relationships that have been constrained by only a few radioisotopic dates. To help improve age constraints, single grains of glauconitic minerals taken from sandstone and limestone in two Proterozoic sequences in the Pranhita-Godavari Valley and the Chattisgarh basin were analyzed by the 40Ar/39Ar incremental heating method. Analysis of the age spectra distinguishes between ages that are interpreted to reflect the time of glauconite formation, and anomalous ages that result from inherited argon or postcrystallization heating. The analyses indicate an age of 1686 ± 6 Ma for the Pandikunta Limestone and 1566 ± 6 Ma for the Ramgundam Sandstone, two units in the western belt of Proterozoic sequences in Pranhita-Godavari Valley. Glauconite from the Chanda Limestone, in the upper part of this sequence, contains inherited 40Ar but is interpreted to reflect an age of ca. 1200 Ma. Glauconite from the Somanpalli Group in the eastern belt of the Pranhita-Godavari Valley gives an age of 1620 ± 6 Ma. In the Chattisgarh basin, glauconite from two units gives disturbed ages that suggest a period of regional heating in the Chattisgarh basin at ca. 960–1000 Ma. These new ages indicate that these sequences are 200–400 m.y. older than previously recognized, which has important implications for geochemical studies of Mesoproterozoic ocean redox conditions in addition to providing important constraints on regional tectonics and lithostratigraphy.

    Background Importance of parasites in ecological and evolutionary interactions is being increasingly recognized. However, ecological data on parasites of important host species is still scanty. We analyze the patterns seen in the faecal parasites of tigers in the Tadoba National Park, India, and speculate on the factors and processes shaping the parasite community and the possible implications for tiger ecology. Results The prevalence and intensities were high and the parasite community was dominated by indirect life cycle parasites. Across all genera of parasites variance scaled with the square of the mean and there was a significant positive correlation between prevalence and abundance. There was no significant association between different types of parasites. Conclusions The 70 samples analyzed formed 14 distinct clusters. If we assume each of the clusters to represent individual tigers that were sampled repeatedly and that resident tigers are more likely to be sampled repeatedly, the presumed transient tigers had significantly greater parasite loads than the presumed resident ones.

    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.

    In the present work, the potential of synthetic aperture radar (SAR) interferometric coherence in land cover classification is studied over forested areas of Bilaspur, Chattisgarh, India using Environmental Satellite--Advanced Synthetic Aperture Radar (ENVISAT-ASAR) C-band data. Single look complex (SLC) interferometric pair ASAR data of 24th September 2006 (SLC-1) and 29th October 2006 (SLC-2) covering the study area were acquired and processed to generate backscatter and interferometric coherence images. A false colored composite of coherence, backscatter difference, and mean backscatter was generated and subjected to maximum likelihood classification to delineate major land cover classes of the study area viz., water, barren, agriculture, moist deciduous forest, and sal mixed forests. Accuracy assessment of the classified map is carried out using kappa statistics. Results of the study suggested potential use of ENVISAT-ASAR C-band data in land cover classification of the study area with an overall classification accuracy of 82.5%, average producer's accuracy of 83.69%, and average user's accuracy of 81%. The present study gives a unique scope of SAR data application in land cover classification over the tropical deciduous forest systems of India, which is still waiting for its indigenous SAR system.

    The Institute of Astronomy and Geophysics Research at King Abdulaziz City for Science and Technology installed nine earthquake portable stations in central part of Saudi Arabia around Riyadh city to record micro- seismicty that is caused by local faults. Riyadh city and central part of Saudi Arabia are located in the Arabian Plate, which is known as a relatively stable platform. However, we have been able to determine some events that was caused by local faults. Most of these events are not felt. We are using digital recorders (RefTek 72A) for data acquisition and SAISAN software for analyses. The velocity model that I have used in this study is IASPEI model. Currently I am developing a map that shows some micro-earthquake events for that region. In addition, it includes some regional events. The objective of this study is to define the active faults in central part of Saudi Arabia.

    The India-Asia collision zone in the Transhimalayan Indus and Shyok Tectonic Belts (STB) of Ladakh, NW India is characterized by two major granitic batholiths. The northern, Karakoram Granitic batholith and the southern, Ladakh Granitic batholith are separated by thrust-bound belts of ophiolite, flysch and calc-alkaline volcanics of Mesozoic to Tertiary age. The KGC can be divided into three zones: a northern zone of metaluminous to mildly peraluminous granodiorite, diorite and tonalite with normative corundum, a southern zone of peraluminous two-mica and garnet bearing granites with normative corundum 1.8-3.3%, K/Rb=200-310, Rb/Sr > 0.3 and initial /sup 87/Sr/ /sup 86/Sr > 0.7113, and a central zone with variable K/Rb, Rb/Sr and initial /sup 87/Sr//sup 86/Sr ratios showing characteristics of both the northern and the southern zones. Field and characteristics of both the northern and the southern zones. Field and geochemical data indicate that: 1) the northern granites of the KGC represent an older magmatic arc derived largely from igneous sources with a small admixture of evolved crustal components and 2) the southern granites of the KGC are derived by partial melting of mature crustal material. Preliminary work in the LGC indicate varying source contamination reflected in variable initial /sup 87/Sr//sup 86/Sr ratios (.7041-.7072) and in correlated /sup 87/Sr//sup 86/Sr vs. delta /sup 18/O plot. The authors data suggest: 1) multiple accretion of Gondwanic fragments in the Mesozoic and Tertiary along the southern margin of Asia, 2) absence of extensive crustal anatexis in the source region of the Ladakh batholith, and 3) remobilization of old sutures and crustal anatexis as a result of India-Asia collision.

    The aim of the study was to explore the effects of domestic employment on the well-being of child domestic workers (CDWs) in India and the Philippines. A questionnaire was administered to 700 CDWs and 700 school-attending controls in the two countries. In India, 36% of CDWs started work before age 12, 48% worked because of poverty or to repay loans, 46% worked >10 h per day, and 31% were physically punished by employers. Filipino CDWs were mainly migrants from rural areas, 47% were working to continue their studies and 87% were attending school, compared with 35% of Indians. In India, 67% of CDWs and 25% of controls scored in the lowest tertile (p<0.001) compared with 36% and 30%, respectively, in the Philippines (p=02). Key significant correlates of low psychosocial scores were non-attendance at school, long working hours, physical punishment, limited support networks and poor health. This study shows that it is not domestic work that is intrinsically harmful, but rather the circumstances and conditions of work, which could be improved through pragmatic regulatory measures.

    In India, Astronomy research institutions are few and far spaced as compared to the population density. Further, the public outreach activities of research institutes cannot cover most of the academic institutes in their area as they way out-number public outreach resource potential of any institute. The organisations of amateur astronomy enthusiasts do come handy in this scenario. We here present a case study of "Khagol Mandal", an a voluntary organisation primarily based in Mumbai, India's economic capital. In 20 years since its inception in 1985-86, Khagol Mandal has given more than 1000 public outreach programmes in various schools, undergraduate colleges, famous city hangouts, apart from their regular overnight programmes in Vangani, a sleepy village on the outskirts of the city. Study tours on special occasions like TSE'95 and TSE'99 as well as regular study tours to meteor crater at Lonar, Maharashtra facilitate their volunteers with glimpses of real research work in astronomy. These have inspired a number of students to take professional astronomy careers. With a volunteer force, probably largest in India or even South Asia, Khagol Mandal is well poised to take advantage of the newest tools like the Virtual Observatory and make the use of existing goodwill to take these tools to the layman. With little guidance from senior researchers, organisations like these can provide a solution to ever increasing need of man power for secondary data analysis.

    Background: The antenatal health-care given to pregnant women has great influence on the rates of perinatal death and morbidity. Amongst the different causes of perinatal mortality, low birth weight (LBW) is the single most significant factor therefore placenta from all the LBW babies (LBWB) should be examined routinely to find out the likely cause. Aims: The aims of this study were to assess the pathological changes in the placenta in association with LBWB. Materials and Methods: This is a Case control study performed at Medical College Allahabad,(MLN) India. In this study, 90 placentae were included. 30 placentae from full-term vaginally delivered babies, weighing more than 2500 g were included as the control group. 60 placentae belonged to babies whose birth weight was less than 2500 g (LBW). Weight of the baby was taken within the 1st h of birth and Apgar score was noted. Gross and microscopic examination of placentae was done. Statistical correlation of was carried out between them by using SPSS 18 version. Chi-square test with or without yate's correction was used as and when required. P < 0.05 was taken as critical level of significance. Results: Placenta was circum-marginal in both groups. Attachment of cord was mainly central in the control group 90% (27/30), whereas eccentric attachment was prominent in patient group 66.67% (40/60). The difference was statistically significant (P < 0.001). Calcification and sub-chorionic fibrin deposition was seen in significantly higher numbers of placentae from patients than controls (P < 0.01) infarction and meconium staining were seen in placentae from patients only. Histologically placental ischemia, infarction and calcification were seen in significantly higher number of patients (P < 0.001, P < 0.001 and < 0.01 respectively). Fibrinoid necrosis, stromal fibrosis, placental dysmaturity and obstructive vasculopathy were seen in placentae from patients only. Conclusion: Placental pathology among LBW infants was high

    Introduction: Diabetes is one of the major health diseases in the world today. The efficacy of Yoga in the management of type 2 diabetes is well-established. The aim of this study was to assess the prevalence of type 2 diabetes among Yoga practitioners in two districts of India (one each in West and South of India). Methodology: In this cross-sectional field study, 155 Yoga practitioners from Pune and 192 from Ernakulam districts were assessed using the diabetes risk test and fasting blood sugar. The data collected were entered in a statistics software package and analyzed using the Pearson's correlation analysis, t-test, univariate ANOVA, and linear regression to understand the predictors of risk for diabetes. Results: The overall prevalence of diabetes among Yoga practitioners in Central Pune was 3.6% (95% confidence interval [CI]: [0.01–0.04]). 18.9% of participants (95% CI: [0.16–0.19]) were diagnosed to be “at risk” for diabetes. In Ernakulam, the overall prevalence of diabetes among practitioners was 26% (95% CI: [0.05-0.06]) with 12% of practitioners (95% CI: [0.05-0.06]) diagnosed to be “at risk” for diabetes (prediabetic). Higher age and lesser duration of Yoga practice were significant predictors of diabetes. Conclusion: It is essential for every person above the age of 40 to undergo regular health check-ups and screening for diabetes and involve oneself in lifestyle modification programs such as Yoga for significantly long duration of time on a daily basis, to better manage diabetes.

    The largest river-valley development to be proposed in India is that in the Narmada valley. The building of the Bargi dam, a multi-purpose irrigation and hydro-electric project, in Jabalpur, in central India, formed part of the first phase of the development of this valley (1974-1988). Many villages and several hectares of land in three districts were submerged as the waters rose behind the dam, the worst affected area being the catchment area of the primary health centre (PHC) at Narayanganj, in Mandla district. Until recently, cases of malaria were relatively rare in Narayanganj. However, an epidemic of malaria in late 1996 claimed hundreds of lives in the area and the outbreak spread, during 1997, to new villages in the region. A review of the records collected by the National Malaria Eradication Programme (NMEP) not only indicated that the slide positivity rate (SPR) for Narayanganj increased > 7.45-fold between 1979 and 1997 but also that the slide falciparum rate (SFR) increased > 32-fold over the same period. The NMEP data available for Mandla district as a whole indicated a doubling in mean SPR and SFR between 1979 and 1997. There is no evidence that a new species of vector has established since 1979. In fact, indoor-resting densities of anophelines and of the most established vector, Anopheles culicifacies, have fallen since the dam was built, but densities of another vector, An. fluviatilis, have increased.

    A charophyte gyrogonite assemblage consisting of Platychara cf. sahnii, Nemegtichara grambastii and Microchara sp. is reported herein from two localities (Bara Simla Hill and Chui Hill sections) of the Lameta Formation at Jabalpur. he Lameta Formation locally underlying the Deccan traps has been shown to be pedogenically modified alluvial plain deposits containing one of the most extensive dinosaur nesting sites in the world. They are associated with dinosaur bones and freshwater ostracod assemblages that suggest a Late Cretaceous (Maastrichtian) age. This is the first detailed systematic account of charophyte gyrogonites from the Lameta Formation. This charophyte assemblage is compatible with the biostratigraphic attribution provided by the ostracods. From a biogeographic viewpoint, it exhibits considerable similarity to other infratrappean assemblages of the Nand, Dongargaon, and Dhamni-Pavna sections (Maharashtra), and some intertrappean assemblages of Kora in Gujarat, Rangapur in Andhra Pradesh and Gurmatkal in South India. Globally, the genus Microchara is well distributed throughout Eurasia, whereas the genus Platychara occurs richly in the Upper Cretaceous deposits of Europe, Asia, America and Africa. However, at the specific level, Platychara cf. sahnii shows close affinities with charophytes from the Maastrichtian of Iran whilst Nemegtichara grambastii shows distinct affinities with two species of Early Palaeogene deposits of China and Mongolia. The presence of charophyte gyrogonites in the Lameta sediments is attributed to local lacustrine and palustrine conditions within a flood plain environment.

    Introduction and Objectives: The central odontogenic fibroma (COF) is a benign odontogenic tumour derived from the dental mesenchymal tissues. It is a rare tumour and only 70 cases of it have been published. Bearing in mind the rareness of the tumour, 8 new cases of central odontogenic fibroma have been found by analyzing the clinical, radiological and histopathological characteristics of COF. Patients and Method: A retrospective study was carried out on 3011 biopsies in the Service of Oral and Maxillofacial Surgery of the Dental Clinic of Barcelona University between January 1995 and March 2008. 85 odontogenic tumours were diagnosed of which 8 were central odontogenic fibroma. The radiological study was based on orthopantomographs, periapical and occlusal radiographies and computerised tomographics. The variables collected were: sex, age, clinical characteristics of the lesion, treatment received and possible reappearances of the tumour. Results: The central odontogenic fibroma represents 9.4% of all odontogenic tumours. Of the 8 cases, 5 were diagnosed in men and 3 in women. The average age was 19.9 years with an age range of 11 to 38 years. The most common location of the tumour was in the mandible. All cases were associated with unerupted teeth. Of the 8 tumours, 3 provoked rhizolysis of the adjacent teeth and 4 cases caused cortical bone expansion. 50% of the patients complained of pain associated to the lesion. No case of recurrence was recorded up to 2 years after the treatment. Conclusions: Central odontogenic fibromas usually evolve asymptomatically although they can manifest very aggressively provoking dental displacement and rhizolysis. Radiologically, COF manifest as a uni or multilocular radiotransparent image although they can be indistinguishable from other radiotransparent lesions making diagnosis more difficult. COF treatment involves conservative surgery as well as follow-up patient checks. Key words: Odontogenic tumour, central odontogenic

    Central Godavari Delta is located in the East coast of Andhra Pradesh along Bay of Bengal. Ample surface water is made available for irrigation and aqua culture through well distributed canals drawn from Godavari River since last 150 years. Groundwater in the area is highly saline though the groundwater levels are very shallow ranging from 1 to 3 m below ground level. Integrated Electrical Resistivity Tomograms (ERT), hydrochemical (pH, TDS, Ca2+, Mg2+, K+, F-, Cl-, SO42-, NO3-, HCO3- and CO3-), isotopic (Br- and δ18O ) and density dependant solute tranport (SEAWAT) modelling studies have been carried out for four years (2006, 2007, 2014 and 2015) to identify the salinity sources and to understand the possible extent of seawater intrusion. The integration of all these data sets revealed that coarse grained sands exhibits resistivity of 4-20 Ωm forming the surface layer, clay layer exhibits < 1 Ωm mostly present as the second layer at many locations. However, similar resistivity values are also associated with soils saturated with sea water. Clay with fine sand occurs as the third layer with a resistivity of 1- 4 Ωm. The different mixing models ((TDS vs. (Na2++ K+) and (Ca2++Mg2+), (Na+-Cl- ) vs. Ca2++Mg2+-HCO3--SO42-)) and ionic ratios ( Na2+/Cl-, SO42-/Cl-, Mg2+/Ca2+, Mg2+/Cl- and Cl-/Br) and δ18O does not reflect any modern seawater signatures. These models indicated that salinity in the shallow wells is due to dissolution of evaporitic minerals and ion exchange processes. In the pumping wells the salinity is due to upconing of entrapped sea water that belongs to Palaeo origin and wells located near the coast and mudflats is due to physical mixing of marine water. The estimated regional groundwater balance using SEAWAT model indicate significant amount of submarine groundwater discharge as outfall to the Bay of Bengal. Assuming observed hydrological conditions, no considerable advance in seawater intrusion would be expected into the delta region.

    Background In 2012, an Indian parliamentary committee reported that manufacturing licenses for large numbers of fixed dose combination (FDC) drugs had been issued by state authorities without prior approval of the Central Drugs Standard Control Organization (CDSCO) in violation of rules, and considered that some ambiguity until 1 May 2002 about states’ powers might have contributed. To our knowledge, no systematic enquiry has been undertaken to determine if evidence existed to support these findings. We investigated CDSCO approvals for and availability of oral FDC drugs in four therapeutic areas: analgesia (non-steroidal anti-inflammatory drugs [NSAIDs]), diabetes (metformin), depression/anxiety (anti-depressants/benzodiazepines), and psychosis (anti-psychotics). Methods and Findings This was an ecologic study with a time-trend analysis of FDC sales volumes (2007–2012) and a cross-sectional examination of 2011–2012 data to establish the numbers of formulations on the market with and without a record of CDSCO approval (“approved” and “unapproved”), their branded products, and sales volumes. Data from the CDSCO on approved FDC formulations were compared with sales data from PharmaTrac, a database of national drug sales. We determined the proportions of FDC sales volumes (2011–2012) arising from centrally approved and unapproved formulations and from formulations including drugs banned/restricted internationally. We also determined the proportions of centrally approved and unapproved formulations marketed before and after 1 May 2002, when amendments were made to the drug rules. FDC approvals in India, the United Kingdom (UK), and United States of America (US) were compared. For NSAID FDCs, 124 formulations were marketed, of which 34 (27%) were centrally approved and 90 (73%) were unapproved; metformin: 25 formulations, 20 (80%) approved, five (20%) unapproved; anti-depressants/benzodiazepines: 16 formulations, three (19%) approved, 13 (81%) unapproved

    We analyse nine years of GPS measurements of crustal deformation from the Koyna-Warna region within the stable India plate. The Koyna-Warna region experienced a strong earthquake on 10 December 1967 (M 6.3) that is considered to have been induced by the impoundment of the Koyna reservoir and the continuing earthquake activity in the region is considered to be associated with the Koyna and Warna reservoirs. The earthquakes occur in a very small region of 30 × 10 km2 in two well defined seismic zones, the NNE-SSW trending Koyna Seismic zone, and the NNW-SSE trending Warna Seismic Zone. These zones are characterised by predominantly left-lateral strike slip motion and normal motion, respectively. In 2003, we initiated campaign-mode GPS measurements in the region. Analysis of the GPS data collected over nine years indicate low to moderate deformation rate (<2 ± 0.5 mm/year) at a few sites within and close to the fault zones and no resolvable deformation elsewhere. This has been seen in many intra-plate seismic regions of the world with varying causative mechanism for the deformation. In the Koyna Warna region, the observed surface displacement rates of up to 2 mm/year near the fault zones are consistent with a fault slip rate of about 7 mm/year, and with the inferred sense of motion on the faults. The inferred fault slip rate is consistent with the total moment release during earthquakes of past six years in the Koyna Warna region which may imply that the ongoing earthquake activity causes the deformation in the region.

    Mercury release by coal combustion has been significantly increased in India. Mercury content in coal has been analyzed to 0.272 ppm by Central Pollution Control Board. Toxicological effects of elemental Hg (Hg0) exposure include respiratory and renal failures, cardiac arrest, and cerebral oedema, while subclinical exposure may induce kidney, behavioral, and cognitive dysfunctions. The present work is focused on dispersion pattern and inter-phase exchange phenomena of ambient mercury between air-particulate matter evaluations of alongwith dominance of various major routes of human exposure-dose response using regression analysis around an integrated steel plant in central India. Source-downwind type stratified random sampling plan using longitudinal study design has been adopted for ambient monitoring of total mercury, while representative sampling plant has been adopted for persona exposure-dose response study In space-time framework. Control sites and subjects have been chosen from uncontaminated area (100 km away from any industrial activities). 06 ambient air monitoring stations and 17 subjects from workers, non-workers but local residents' categories and from controlled sites have been chosen for the study. Samples of mercury biomarkers (blood, breast milk and urine) have also been collected from same subjects in each month during sampling period. The sampling period was March 2005 to February 2006 . Samples of 30% acidified KMnO4 for air-Hg absorption, PM10, RPM and biological samples were analyzed for total mercury by ICP-AES using standard methods. Local soils and ground water were also monitored for total mercury content during the sampling period. Results have shown that mercury concentration is very high compared to prescribed limits in all receptors. Results of exchange phenomenon have shown the higher transfer of mercury from air to particulate during combustion in steel plant environment due to presence of huge amount of iron particles, in contrast to

    Detrital mode, composition of feldspars and heavy minerals, and major element chemistry of sandstones from the Permo-Triassic succession in the intracratonic Satpura Gondwana basin, central India have been used to investigate provenance. The Talchir Formation, the lowermost unit of the succession, comprises glacio-marine and glacio-fluvial deposits. The rest of the succession (base to top) comprising the Barakar, Motur, Bijori, Pachmarhi and Denwa formations, largely represent variety of fluvial depositional systems with minor fluvio-deltaic and fluvio-lacustrine sedimentation under a variety of climatic conditions including cold, warm, arid, sub-humid and semi-arid. QFL compositions of the sandstones indicate a predominantly continental block provenance and stable cratonic to fault-bounded basement uplift tectonic setting. Compositional maturity of sandstones gradually increases upwards from the Early Permian Talchir to the Middle Triassic Denwa but is punctuated by a sharp peak of increased maturity in the Barakar sandstones. This temporal change in maturity was primarily controlled by temporal variation in fault-induced basement uplift in the craton and was also influenced by climatic factors. Plots of different quartz types suggest plutonic source rocks for the Talchir sandstones and medium-to high-rank metamorphic plus plutonic source rocks for the younger sandstones. Composition of alkali feldspars in the Permo-Triassic sandstones and in different Precambrian rocks suggests sediment derivation from felsic igneous and metasedimentary rocks. Compositions of plagioclase in the Talchir and Bijori sandstones are comparable with those of granite, acid volcanic and metasedimentary rocks of the Precambrian basement suggesting the latter as possible source. Rare presence of high-K plagioclase in the Talchir sandstones, however, indicates minor contribution from volcanic source rock.

    We present 40Ar/ 39Ar whole-rock ages of 63.7 ± 2.7 Ma (2σ, 92% Ar release) and 66.6 ± 2.2 Ma (2σ, 96% Ar release) for two samples of sub-surface mafic dykes intrusive into the sedimentary rocks of the Mesoproterozoic Chhattisgarh basin, Bastar craton, Central India. The obtained ages are synchronous with those of the Deccan Traps whose nearest exposures are at a distance of ~ 200 km to the west, and the recently dated diamondiferous orangeites (Group-II kimberlites) of the Mainpur area (located ~ 100 km SE within the Bastar craton). The chemical composition of the Chhattisgarh mafic dykes is indistinguishable from the chemostratigraphic horizons of the upper Deccan lavas of the Wai Subgroup (Ambenali and Poladpur Formations) and confirms them to be a part of the Deccan Large Igneous Province (LIP). The geological setting of the Deccan-age mafic dykes in the Chhattisgarh basin is analogous to that observed in other LIPs of the world such as (i) Pasco Basin of NW U.S.A, (ii) Ellisras sub-basin of southern Africa, (iii) Rift basins of New England in the NE U.S.A and (iv) the West Siberian Basin of Russia where LIP-related basalts and sills have been emplaced in distant domains from the main province. The Deccan-age of the Chhattisgarh dykes and the Mainpur orangeites permits a substantial increase of at least 8.5 × 10 4 km 2 in the spatial extent of the Deccan LIP. The temporal link at ~ 65 Ma between the Deccan Traps and (i) sub-surface mafic dykes within the Chhattisgarh basin and orangeites in the Bastar craton, (ii) Ambadongar carbonatite in western India, (iii) Salma mafic dyke in the Eastern Indian craton, (iv) Rajahmundry Traps off the eastern coast of southern India and (v) tholeiitic dykes and basalts from the Seychelles, suggests a common tectonomagmatic control, via a vast mantle plume-head of the order of 2000-2500 km. Our study has relevance to the (i) origin (plume vs non-plume) of the Deccan LIP, (ii) plumbing system for Deccan dykes and lavas in

    The major objective of this project was to assess chemical and morphological modifications occurring in muscle receptors and the central nervous system of animals subjected to altered gravity (2 x Earth gravity produced by centrifugation and simulated micro gravity produced by hindlimb suspension). The underlying hypothesis for the studies was that afferent (sensory) information sent to the central nervous system by muscle receptors would be changed in conditions of altered gravity and that these changes, in turn, would instigate a process of adaptation involving altered chemical activity of neurons and glial cells of the projection areas of the cerebral cortex that are related to inputs from those muscle receptors (e.g., cells in the limb projection areas). The central objective of this research was to expand understanding of how chronic exposure to altered gravity, through effects on the vestibular system, influences neuromuscular systems that control posture and gait. The project used an approach in which molecular changes in the neuromuscular system were related to the development of effective motor control by characterizing neurochemical changes in sensory and motor systems and relating those changes to motor behavior as animals adapted to altered gravity. Thus, the objective was to identify changes in central and peripheral neuromuscular mechanisms that are associated with the re-establishment of motor control which is disrupted by chronic exposure to altered gravity.

    Sloth bears (Melursus ursinus) are endemic to the Indian subcontinent. As a result of continued habitat loss and degradation over the past century, sloth bear populations have been in steady decline and now exist only in isolated or fragmented habitat across the entire range. We investigated the genetic connectivity of the sloth bear meta-population in five tiger reserves in the Satpura-Maikal landscape of central India. We used noninvasively collected fecal and hair samples to obtain genotypic information using a panel of seven polymorphic loci. Out of 194 field collected samples, we identified 55 individuals in this meta-population. We found that this meta-population has moderate genetic variation, and is subdivided into two genetic clusters. Further, we identified five first-generation migrants and signatures of contemporary gene flow. We found evidence of sloth bears in the corridor between the Kanha and Pench Tiger Reserves, and our results suggest that habitat connectivity and corridors play an important role in maintaining gene flow in this meta-population. These corridors face several anthropogenic and infrastructure development threats that have the potential to sever ongoing gene flow, if policies to protect them are not put into action immediately.

    Crop raiding by wild herbivores close to an area of protected wildlife is a serious problem that can potentially undermine conservation efforts. Since there is orders of magnitude difference between farmers’ perception of damage and the compensation given by the government, an objective and realistic estimate of damage was found essential. We employed four different approaches to estimate the extent of and patterns in crop damage by wild herbivores along the western boundary of Tadoba-Andhari Tiger Reserve in the state of Maharashtra, central India. These approaches highlight different aspects of the problem but converge on an estimated damage of over 50% for the fields adjacent to the forest, gradually reducing in intensity with distance. We found that the visual damage assessment method currently employed by the government for paying compensation to farmers was uncorrelated to and grossly underestimated actual damage. The findings necessitate a radical rethinking of policies to assess, mitigate as well as compensate for crop damage caused by protected wildlife species. PMID:27093293

    The Austroasiatic linguistic family disputes its origin between two geographically distant regions of Asia, India, and Southeast Asia, respectively. As genetic studies based on classical and gender-specific genetic markers provided contradictory results to this debate thus far, we investigated the HLA diversity (HLA-A, -B, and -DRB1 loci) of an Austroasiatic Munda population from Northeast India and its relationships with other populations from India and Southeast Asia. Because molecular methods currently used to test HLA markers often provide ambiguous results due to the high complexity of this polymorphism, we applied two different techniques (reverse PCR-SSO typing on microbeads arrays based on Luminex technology, and PCR-SSP typing) to type the samples. After validating the resulting frequency distributions through the original statistical method described in our companion article ( Nunes et al. 2011 ), we compared the HLA genetic profile of the sampled Munda to those of other Asiatic populations, among which Dravidian and Indo-European-speakers from India and populations from East and Southeast Asia speaking languages belonging to different linguistic families. We showed that the Munda from Northeast India exhibit a peculiar genetic profile with a reduced level of HLA diversity compared to surrounding Indian populations. They also exhibit less diversity than Southeast Asian populations except at locus DRB1. Several analyses using genetic distances indicate that the Munda are much more closely related to populations from the Indian subcontinent than to Southeast Asian populations speaking languages of the same Austroasiatic linguistic family. On the other hand, they do not share a closer relationship with Dravidians compared with Indo-Europeans, thus arguing against the idea that the Munda share a common and ancient Indian origin with Dravidians. Our results do not favor either a scenario where the Munda would be representative of an ancestral Austroasiatic

    Firearm (FA) injuries pose great health burden and presents enormous challenge for health and national economies. This study was undertaken to analyze the characteristics of fatal gunshot injuries, their pattern, associated factors, and postmortem findings in central India, to provide data for such fatalities in this region, which has not been reported earlier. This is a descriptive, retrospective cross-sectional study carried out on the victims of FA injuries referred to the mortuary. Of the autopsies conducted during study, 2.09% were firearm-related deaths. Of the cases, males (92.42%) notably outnumbered females in a ratio of 12.2:1. Homicidal attacks were maximum, and unlicensed, illegal country-made weapons were the preferred choice. Suicides were least. Result signifies that illegal country-made weapons should be strictly limited to save the precious lives. A holistic approach encompassing public awareness, behavioral modification, and stringent management of law and order is the need of the hour. PMID:25381843

    This study assesses the level of natural radioactivity due to radionuclides, ²³⁸U, ²³²Th and ⁴⁰K, in 50 soil samples collected from South Konkan, Maharashtra, India. The mean activity concentrations of ²³⁸U, ²³²Th and ⁴⁰K are 44.97 ± 1.22 Bq kg⁻¹, 59.70 ± 2.17 Bq kg⁻¹ and 217.51 ± 8.75 Bq kg⁻¹, respectively, measured from all the soil samples studied. The good correlation between activity concentration of U-238 and Th-232; U-238 and K-40 as well as between activity concentration of Th-232 and K-40 was observed. The average calculated absorbed dose rate in air (68.08 nGy h⁻¹) was found to be higher than the world average of 57 nGy h⁻¹ (UNSCEAR 2000). Radium equivalent activity for all the villages was found to be lower than the worldwide value. The values of external hazard index and internal hazard index determined from all the soil samples were found to be within recommended limit. The calculated average annual effective dose was found to be 0.42 mSv y⁻¹, and it is lower than the worldwide value of 0.46 mSv y⁻¹.The annual effective dose values calculated from present study were comparable with previous studies carried out in other countries and in India. The data established from the study can be useful as baseline information on natural radioactivity in South Konkan, Maharashtra, India. PMID:23704360

    A five-year epidemiologic study of patients attending a malaria clinic in Delhi was conducted to find the relapse rate of infections with Plasmodium vivax, its seasonal correlation between the primary infection and subsequent relapses, the duration of the incubation period, and the patterns of relapse. By our definition, the relapse rate ranged from 23% to 44% depending on the duration of follow-up. The relapse pattern observed in the study clearly suggests the existence of both tropical and temperate zone types of P. vivax in the population characterized by distinct incubation periods and the possible existence of P. vivax subpopulations characterized by primary long incubation periods. The implication of different incubating forms of P. vivax on the epidemiology and control of malaria is also discussed. PMID:9684649

    Present study aimed to compare the incidence of menopausal problems and concomitants between tribe and caste population. This cross section study was conducted in five villages of West Bengal, a state in the eastern part of India. This study was conducted between two different ethnic groups—one of the “Particularly Vulnerable Tribal Groups (PTG)” of India named as “Lodha” and the other was a Bengali speaking caste population. A total number of 313 participants were finally recruited for this study. Study participants were married, had at least one child, had no major gynaecological problems, and had stopped menstrual bleeding spontaneously for at least 1 year. Additionally, data on sociodemographic status and menstrual and reproductive history were collected using a pretested questionnaire/schedule. Bivariate analyses (chi square test) revealed that significantly more number of caste participants suffered from urinary problems than their tribe counterpart. The reverse trend has been noticed for the frequency of vaginal problems. Multivariate analyses (binary logistic regression) show that sociodemographic variables and menstrual and reproductive history of the present study participants seem to be the concomitants of menopausal symptoms. Tribe and caste study population significantly differed with respect to the estrogen deficient menopausal problems and the concomitants to these problems. PMID:26294906

    The ENE-WSW trending Gavilgarh Fault Zone (GFZ) is an important tectonic lineament within the Central Indian shield. Geomorphological mapping and spatial analyses of rivers were carried out to elucidate the imprints of active tectonics on the fluvial systems of this region. The sinuosity index, width-depth ratio of river valleys, longitudinal profile, S-L index and hypsometric index of the rivers flowing from north to south across the GFZ lineament suggest that the northern side of GFZ was tectonically uplifted. Luminescence dating of sediments from river terraces and calculation of knickpoint migration rates in the rivers indicate occurrence of multiple neotectonic events in GFZ at ca. 65-80 ka, ca. 50 ka, ca. 30-40 ka, and ca. 14 ka. Evidences of neotectonic activity, presence of active geothermal springs, and occurrence of recent earthquakes along GFZ suggest that this lineament is tectonically active and there is a need for proper seismic monitoring of this fault zone.

    The Bundelkhand Gneissic Complex (BnGC) in the central part of the Bundelkhand massif preserves a supracrustal unit which includes pelitic (garnet-cordierite-sillimanite gneiss, garnet-sillimanite gneiss, biotite gneiss and garnet-biotite gneiss) and mafic (hornblende-biotite gneiss and garnetiferous amphibolite) rocks. Granulite facies metamorphism of the complex initiated with breaking down of biotite to produce garnet and cordierite in the pelitic gneisses. Geothermobarometric calculations indicate metamorphic conditions of 720°C/6.2 kbar, followed by a retrograde (687°C/4.9 kbar) to very late retrograde stages of metamorphism (579°C/4.4 kbar) which is supported by the formation of late cordierite around garnet. The P-T conditions and textural relations of the garnet-cordierite-bearing gneiss suggest a retrograde cooling path of metamorphism.

    Background Although male circumcision (MC) is recommended as an HIV prevention option, the religious, cultural and biomedical dimensions of its feasibility, acceptability and practice in India have not been explored till date. This study explores beliefs, experiences and understanding of the community and healthcare providers (HCPs) about adult MC as an HIV prevention option in India. Methods This qualitative study covered 134 in-depth interviews from Belgaum, Kolkata, Meerut and Mumbai cities of India. Of these, 62 respondents were the members of circumcising (CC)/non-circumcising communities (NCC); including medically and traditionally circumcised men, parents of circumcised children, spouses of circumcised men, and religious clerics. Additionally, 58 registered healthcare providers (RHCPs) such as general and pediatric surgeons, pediatricians, skin and venereal disease specialists, general practitioners, and operation theatre nurses were interviewed. Fourteen traditional circumcisers were also interviewed. The data were coded and analyzed in QSR NUD*IST ver. 6.0. The study has not explored the participants' views about neonatal versus adult circumcision. Results Members of CC/NCC, traditional circumcisers and RCHPs expressed sharp religious sensitivities around the issue of MC. Six themes emerged: Male circumcision as the religious rite; Multiple meanings of MC: MC for ‘religious identity/privilege/sacrifice’ or ‘hygiene’; MC inflicts pain and cost; Medical indications outweigh faith; Hesitation exists in accepting ‘foreign’ evidence supporting MC; and communication is the key for acceptance of MCs. Medical indications could make members of NCC accept MC following appropriate counseling. Majority of the RHCPs demanded local in-country evidence. Conclusion HCPs must educate high-risk groups regarding the preventive and therapeutic role of MC. Communities need to discuss and create new social norms about male circumcision for better societal acceptance

    2004-02-01

    The pollution of aquatic ecosystem by heavy metals has assumed serious proportions due to their toxicity and accumulative behavior. The toxicity and fate of the water borne metal is dependent on its chemical form and therefore quantification of the different forms of metal is more meaningful than the estimation of its total metal concentrations. In this study fractionation of metal ions on bed sediments of River Yamuna has been studied to determine the eco-toxic potential of metal ions. The investigations suggest that copper have a tendency to remain associated with residual, reducible and carbonate fractions. The Risk Assessment Code reveal that about 30-50% of lead at most of the sites exist in exchangeable fraction while 30-50% of cadmium at almost all the sites is either exchangeable or carbonate bound and therefore comes under the high risk category and can easily enter the food chain. Most of the copper is in immobile fraction at Delhi while at other sites, a sizable portion (10-30%) is found in carbonate fraction thus posing medium risk for the aquatic environment. Fractionation pattern of zinc shows low to medium risk to aquatic environment. PMID:14723925

    Epidemiological and medicolegal, including forensic pathological, aspects of 456 cases of unnatural deaths of females aged 16 to 30 years were studied in Lucknow during the period of 1 year (May 2, 2011 to May 1, 2012). These constituted 62.5% of the total unnatural deaths autopsied from all ages in females. Most of the victims were young Hindu housewives killed or who died within 7 years of marriage. The most common cause was vehicular accidents followed by poisons and burns. The homicidal, suicidal, and accidental deaths were 87, 129, and 240, respectively. The common motives and circumstances were mental stress due to various reasons, family quarrel, maladjustment in married life, and cruelty by the in-laws. Level of education, joint family structure, unemployment, dependence of the woman on the in-laws, infidelity, large families, and failure in love in unmarried girls were other contributing factors affecting the incidence. The study suggests different measures to check unnatural female deaths to improve the situation. PMID:24141355

    Suicide is one of the ten leading causes of death in the world, accounting for more than a million deaths annually. The purpose of the study was to identify the risk groups. In the four-year period from January 2000 to December 2003, 588 suicide victims were autopsied. Information was obtained by interviewing the acquaintances of the victim, perusal of hospital records and the autopsy findings. All the cases were analyzed as to sex, age, and methods of suicide, seasonal variation, diurnal variation and other sociological aspects. The present study depicts a suicidal rate of 11.76 per 100,000 population. Males and females were almost equally the sufferers. The largest number of victims were found in the age group of 21-30 years. Hanging and poisoning constituted the two major modes of suicides (63%). Majority of the victims were mentally sound, married and were from rural background. Victims were mostly drawn from low socioeconomic status (48%). Less educated or illiterates were usually the victims. Suicidal note was detected in 5% of cases. Suicidal tendency and alcohol intake could not be encountered in most of the cases. Indoor incidence was almost double of the outdoor incidence, mostly seen in rainy season (43%) and occurred almost equally during day and night. Financial burden (37%) and marital disharmony (35%) were the principal reasons for the suicide. PMID:16914358

    west of Australia, in particular the Wallaby-Zenith Plateau Ridge and the Wallaby-Zenith Fracture Zone. We suggest that the Indian continent probably extended no more than 950 km in the central portion of the Main Boundary Thrust, up to the Wallaby-Zenith Fracture Zone. At the Western Syntaxis, the extension was about 600 km. These estimates are broadly compatible with some of the geophysically-derived models depicting subducted Indian lithosphere beneath Tibet, as well as estimates of Himalayan shortening. Models requiring sub-continent extensions > 9° ahead of the craton are probably wrong. We also suggest that northern India did not have a thinned rifted passive margin due to the earlier rifting of blocks away from it when it formed part of Gondwana. Instead, the boundary developed as a transform fault and probably had a very narrow ocean-continent transition zone (5-10 km wide), similar to the Romanche Fracture Zone offshore of Ghana, West Africa.

    This study assessed the use of spectacles and its demographic associations in a sample representative of the population of the Indian state of Andhra Pradesh. A total of 11,786 subjects of all ages were sampled from 94 clusters in one urban and three rural study areas of Andhra Pradesh using stratified, random, cluster, systematic sampling. The eligible subjects underwent detailed interview and eye examination including dilated examination of the posterior segment. The data on the use of spectacles were analysed for subjects > 15 years of age. A total of 7,432 subjects > 15 years of age participated in the study of whom 1,030 (13.8%) had a refractive error of spherical equivalent +/- 3.00 Diopter or worse. The prevalence of current use of spectacles in those with spherical equivalent +/- 3.00 Diopter or worse, who were likely to be visually impaired without refractive correction, was 34.2% (95% confidence interval 30.3-38%) and of previous use of spectacles was 12.3% (95% confidence interval 10.3-14.3%). The odds of using spectacles currently were significantly higher for those with any level of education, those living in the urban area, and for those with aphakia or psuedophakia as compared with natural refractive error. Among those who had used spectacles previously, 43.8% had discontinued because they felt that either the prescription was incorrect or that the spectacles were uncomfortable, suggesting poor quality of refractive services, and another 19.6% had lost the pair and could not afford to buy another pair. These data suggest that the use of spectacles in this population by those with refractive error was not optimal. Two-thirds of those with spherical equivalent +/- 3.00 Diopter or worse were not using spectacles. Of those who had discontinued the use of spectacles, a significant proportion did so for reasons related to poor quality of refractive services. Strategies such as vision screening programmes and eye health promotion need to be implemented, the

    Salem is one of the industrial, agricultural and mineral deposit based district in Tamil Nadu. In this paper, an attempt is made to assess the quality of groundwater in this district, during the month of May 2007 (pre-monsoon). The government of Tamil Nadu has divided the district into twenty blocks. Sixty six samples were collected covering all the blocks of the district except Yercaud which is a structural hill. The collected samples were tested for the following parameters: electrical conductivity, turbidity, pH, total hardness, iron, chlorides, total dissolved solids, calcium, magnesium, potassium, manganese, sulphate, nitrate, nitrite and total alkalinity. The test results were interpreted using IS 10500-1991, statistical methods, SAR, USSL classification and Piper's trilinear diagram. Based on the interpretation it is concluded that the study area is mostly influenced by the presence of electrical conductivity, total dissolved solids, total hardness, chloride and total alkalinity whereas the other minerals and salts play a minor role.

    On-line shopping is a recent phenomenon in the field of E-Business and is definitely going to be the future of shopping in the world. Most of the companies are running their on-line portals to sell their products/services. Though online shopping is very common outside India, its growth in Indian Market, which is a large and strategic consumer market, is still not in line with the global market. The potential growth of on-line shopping has triggered the idea of conducting a study on on-line shopping in India. The present research paper has used exploratory study to depict and highlight the various categories of factors and variables impacting the behavior of consumers towards on-line shopping in India. The data was collected through in-depth interviews on a sample of 41 respondents from Delhi, Mumbai, Chennai and Bangalore. The results of the study show that on-line shopping in India is basically impacted by five categories of factors like demographics factor, Psychographics factor, Online shopping feature and policies, Technological factor, Security factor. The results of the study are used to present a comprehensive model of on-line shopping which could be further used by the researchers and practitioners for conducting future studies in the similar area. A brief operational definition of all the factors and variables impacting on-line shopping in India is also described. And finally practical implications of the study are also elucidated.

    Ceppi, Sofia; Gatti, Nicola

    The deregulation of electricity markets produced significant economic benefits, reducing prices to customers and opening several opportunities for new actors, e.g., new generators and distributors. A prominent scientific and technological challenge is the automation of such markets. In particular, we focus our attention on wholesale electricity markets based on a central auction. In these markets, generators sell electricity by means of a central auction to a public authority. Instead, the distribution of electricity to customers takes part in retail markets. The main works presented in the literature model wholesale markets as oligopolies, neglecting thus the specific auction mechanism. In this paper, we enrich these models by introducing an auction mechanism shaped on that used in the Italian wholesale electricity market, we solve the winner determination problem, and we preliminarily study the problem of searching for equilibria.

    Little is known of the local astronomies of central Africa, and because of decades of horrific civil strife, this is particularly true of the Democratic Republic of the Congo (DRC). The present case study combines archival consideration of unpublished letters by earliest European visitors with ethnographic research in the mid-1970s among Tabwa and related peoples living along the western shores of and inland from Lake Tanganyika. Early data are very sparse, and in more recent days local astronomy is little-developed; but hypotheses are nonetheless possible about how people understood the regularities of the heavens as well as astonishing events like the apparition of Sungrazer Comets of the 1880s. A mnemonic logic shared by Tabwa, Luba, and other regional groups that was sometimes given material form or realized through performance arts may have informed how central African skies were "read" in earlier times.

    This thesis analyses the feasibility of various sources of energy for the development of agriculture on the Indian subcontinent. There is a large potential for futher use of groundwater for irrigation in the northeast Indian plains and this study examines the trade-off between the benefits to agriculture of irrigation and the costs of the energy and equipment required for pumping. A linear programming model has been developed to predict the general equilibrium state of the economy of Pulkahi, a typical poor village in the Indian State of Bihar. This model has been used to predict the effects on agricultural production of various technological endowments. Four different methods of pumping water were considered in detail. These were: diesel engines fueled with diesel oil, diesel engines with biogas plants fueled with dung, diesel engines with gasifiers fueled with residues or wood, and animal powered pumps. Gasifiers convert wood or residues to a combustible gas (primarily hydrogen and carbon monoxide) through a process of partial combustion. Biogas plants use anaerobic decomposition to produce methane. Only small size pumps suitable for use by individual farmers, or small cooperatives were considered. As most biomass is already used for some purpose (e.g. fertilizer, fuel) special attention was given to the balance of nitrogen within the village system.

    Glacial lake outburst flood (GLOF) is one of the major unexpected hazards in the high mountain regions susceptible to climate change. The Tawang river basin in Arunachal Pradesh is an unexplored region in the Eastern Himalayas, which is impending to produce several upcoming hydro-electric projects (HEP). The main source of the river system is the snow melt in the Eastern Himalayas, which is composed of several lakes located at the snout of the glacier dammed by the lateral or end moraine. These lakes might prove as potential threat to the future scenario as they have a tendency to produce flash flood with large quantity of sediment load during outbursts. This study provides a methodology to detect the potential lakes as a danger to the HEP sites in the basin, followed by quantification of volume of discharge from the potential lake and prediction of hydrograph at the lake site. The remote location of present lakes induced the use of remote sensing data, which was fulfilled by Landsat-8 satellite imagery with least cloud coverage. Suitable reflectance bands on the basis of spectral responses were used to produce informational layers (NDWI, Potential snow cover map, supervised classification map) in GIS environment for discriminating different land features. The product obtained from vector overlay operation of these layers; representing possible water area, was further utilized in combination with Google earth to identify the lakes within the watershed. Finally those identified lakes were detected as potentially dangerous lakes based on the criteria of elevation, area, proximity from streamline, slope and volume of water held. HEC-RAS simulation model was used with cross sections from Google Earth and field survey as input to simulate dam break like situation; hydrodynamic channel routing of the outburst hydrograph along river reach was carried out to get the GLOF hydrograph at the project sites. It was concluded from the results that, the assessed GLOF would be a

    Population growth and industrialization is progressing at an unprecedented rate on a global scale. One region undergoing a particularly fast transition is India. These changes are accompanied, among others, by a substantial increase in aerosol emission. To learn more about associated consequences for the climate system we have carried out a comparatively large set of transient sensitivity studies with the global atmosphere only climate model ECHAM5-HAM, using aerosol emission data from NIES (National Institute of Environmental Studies, Japan) and prescribed, observation based sea surface temperatures (SSTs) from the Hadley Center. The sensitivity studies cover the period from 1870 to 2005 and comprise ensembles of simulations (up to 13 members per ensemble), which allow to address the role of different aerosol species, greenhouse gases, and prescribed sea surface temperatures. We present and analysis of these simulation data with particular focus on surface solar radiation (SSR) and precipitation in India, and discuss potential physical mechanisms involved. Modeled annual mean SSR is found to decrease over the Indian subcontinent (land between 67E / 90E / 10N / 25N) at a rate of about -3 to -4 W/m2 per decade. This dimming is roughly in line with observation based estimates. The decrease is comparable under all sky conditions. Regional and seasonal differences are substantial, with the Ganges plane showing the strongest dimming. Aerosols are transported far out over the Indian ocean, leading to a substantial decrease in SSR also there. Modeled precipitation captures well the annual monsoon cycle. The observed, recent decrease in precipitation is, however, overestimated by the model. More precisely, the model captures the observed precipitation reduction in northern India in July / August, but not the observed increase in precipitation in May / June. Our sensitivity studies suggest that the atmosphere only response to increasing aerosol emissions is a reduction of

    The goal of sustainable agricultural and watershed management is to enhance agricultural productivity while protecting and preserving our environment and natural resources. The vast majority of information on sustainable watershed management practices is primarily derived from studies in developed nations with very few inputs from developing nations. Through a USDA-funded project, the University of Delaware (UD) initiated a collaboration with the International Crop Research Institute for the Semi-Arid Tropics (ICRISAT) located in Hyderabad, India to study sustainable agricultural management practices in developing countries and their impacts on the environment, crop productivity, and socioeconomic conditions of the watershed community. As a part of this project, ICRISAT provided us with a vast amount of data on sustainable agricultural practices and their impacts on runoff, soil and water quality, crop yields, nutrient management and socioeconomic conditions. Conservation practices that were implemented included check dams, groundwater recharge wells, intercropping, nutrient management, integrated pest management and a suite of other practices. Using this information, students and faculty at UD developed teaching modules that were used for education and enrichment of existing UD courses and are also being used for the development of a stand-alone online course. The students and faculty visited India in July 2010 to get a first-hand experience of the conditions in the agricultural watersheds and the impacts of sustainable management practices. The project was a tremendous learning experience for US students and faculty and highlighted the challenges people face in developing countries and how that affects every aspect of their lives. Such challenges include environmental, agricultural, technological, economic, and transportation. Although we experience many of the same challenges, developing countries do not have the technology or economic infrastructure in place to

Water samples from different sampling locations were collected and processed for physico-chemical analysis. The physico-chemical analysis revealed that the reservoir is favourable for fish culture as the phosphate content in water is moderate in amount. This reservoir can produce a good yield of fishes. Though the reservoir is presently exploited and is under pisciculture, a better treatment of the reservoir such as prevention of entry of organic matter, reduction of phosphate ion concentration to certain extent is necessary to obtain a maximum fish yield.

    Formative data on the sexual behaviors of HIV-infected individuals in regions disproportionately affected by the epidemic can help generate hypotheses about sexual risk taking in HIV-infected individuals and shape interventions to prevent further transmission. India is home to the highest number of HIV-infected individuals in the world, and very little information is available about the sexual behaviors of HIV-infected Indians. The present qualitative study presents themes from individual in-depth interviews with 30 HIV-infected individuals in South India. The sample included individuals from demographic groups that may experience different risk factors (five individuals each: from men who have sex with men, sex workers, married men, married women, injection drug users, and truck drivers ormen who travel for work). Across the groups, the three most frequently discussed themes involved (a) sexual behavior change (sexual risk reduction after HIV diagnosis, sexual behavior remaining safe after initiation of ART treatment), (b) motivations to reduce risk (motivation to protect one's self against further infection, to protect others from infection), and (c) barriers to reduce risk (complexity and stigma associated with condom negotiation, perception of HIV-infected peers being less concerned about protecting others, condom use as linked to gender and sexual roles, condom use as inconvenient or unappealing). This qualitative data can be used to generate hypotheses about sexual risk taking in HIV-infected individuals in South India, to inform models of risky behaviors of HIV-infected individuals for quantitative studies, and to lay the groundwork for secondary prevention intervention efforts that enhance facilitators and reduce barriers of safer sex articulated by the interviewees.

    Connection of air quality with human health is well established in the literature. However the associated health risks due to fine particulate matter (PM2.5) concentration is not well known in India, while the assigned mean threshold values are 60 μg/m3 for 24-hour period and 40 μg/m3 for annual period. Both are considered safe concentration limits regarding human health effects. However, the daily and annually concentrations of PM2.5 were observed more than three times of NAAQS in the present study for a year. This study relates the incessant exposure to significant levels of PM2.5 to deleterious health effects, such as heart and lung diseases. The relation between environmental air quality and human health has been studied through different parameters e.g., hazard quotient (HQ), lifetime incremental cancer risk (LICR), and individual risk for different groups of ages in Delhi, the capital city of India. These analysis lead to additional insights into health disparities and may suggest that more rigorous strategies. This may be application to other urban areas across the nation. In this study, we propose to quantify such impacts through estimation of different health risk factors.

    The U.S. Geological Survey (USGS) and the Geological Survey of India (GSI) are concluding a cooperative study of the coking coal deposits in the Sohagpur coal field in central India. Because of the importance of coal in India's economy, the Coal Wing of the Geological Survey of India has studied the area intensely since the early 1980's. This report summarizes the overall stratigraphic, tectonic, and sedimentologic framework of the Sohagpur coal field area, and the interpretations of the geologic and climatic environments required for the accumulation of the thick Gondwana coal deposits, both coking and non-coking.

    Aim: This systematic literature review was conducted to identify, evaluate, and characterize the variety, quality, and intent of the health economics and outcomes research studies being conducted in India. Materials and Methods: Studies published in English language between 1999 and 2012 were retrieved from Embase and PubMed databases using relevant search strategies. Two researchers independently reviewed the studies as per Cochrane methodology; information on the type of research and the outcomes were extracted. Quality of reporting was assessed for model-based health economic studies using a published 100-point Quality of Health Economic Studies (QHES) instrument. Results: Of 546 studies screened, 132 were included in the review. The broad study categories were cost-effectiveness analyses [(CEA) 54 studies], cost analyses (19 studies), and burden of illness [(BOI) 18 studies]. The outcomes evaluated were direct and indirect costs, and incremental cost-effectiveness ratio (ICER), quality-adjusted life years (QALYs), and disability-adjusted life years (DALYs). Direct medical costs assessed cost of medicines, monitoring costs, consultation and hospital charges, along with direct non-medical costs (travel and food for patients and care givers). Loss of productivity and loss of income of patients and care givers were identified as the components of indirect cost. Overall, 33 studies assessed the quality of life (QoL), and the WHO Quality of Life-BREF (WHOQOL-BREF) was the most commonly used instrument. Quality assessment for modeling studies showed that most studies were of high quality [mean (range) QHES score to be 75.5 (34-93)]. Conclusions: This review identified various patterns of pharmacoeconomic studies and good-quality CEA studies. However, there is a need for better assessment of utilization of healthcare resources in India. PMID:25657899

    A number of ENE-WSW trending Paleoproterozoic dykes and plugs of mafic, ultramafic, alkaline and carbonatite rocks intrude Mahakoshal supracrustal belt (MSB), which is a part of the Central Indian Tectonic Zone (CITZ). Best exposures of these intrusions are found in the eastern parts of the MSB, particularly in and around Chitrangi area. Many of these intrusions have greenschist facies mineral composition and show sharp contact with supracrustal rocks. However, igneous textures, such as porphyritic/glomeroporphyritic, are still preserved in the form of partly pseudomorphed olivines, phlogopites and pyroxenes. Striking feature observed in some ultramafic samples is the presence of melanite garnet and rounded or elliptical carbonate ocelli. The petrographic characteristics suggest occurrence of carbonate-rich ultramafic lamprophyres; close to aillikite composition. Coarse-grained carbonatites show hypidiomorphic texture and mostly composed of calcite with appreciable amount of silicate minerals like clinopyroxene, phlogopite and olivine (often pseudomorphed by calcite, amphibole and chlorite). It is difficult to establish any direct genetic relationship between carbonatite and ultramafic lamprophyre samples on the basis of their chemistry; they were likely derived from distinct parental melts. High Mg# (up to ~78), and high Ni and Cr contents (up to ~1700 and ~1100, respectively) and low HREE concentration in few ultramafic lamprophyre samples apparently suggest their derivation from a near-primary mantle-derived melts originated at great depths. Geochemistry and presence of carbonate ocellae in ultramafic lamprophyre samples suggest genesis of these silicate rocks and associated carbonatites through liquid immiscibility, however possibility of their derivation through vein-plus-wall-rock melting model cannot be ignored. A multi-stage veined mantle melting model is suitable in the latter case. It is suggested that early stages of rifting in the Mahakoshal region due

    Background Bypassing available facilities for childbirth has important implications for maternal health service delivery and human resources within a health system. The results are the additional expenses imposed on the woman and her family, as well as the inefficient use of health system resources. Bypassing often indicates a lack of confidence in the care provided by the facility nearest to the mother, which implies a level of dysfunctionality that the health system needs to address. Over the past decade, India has experienced a steep rise in the proportion of facility births. The initiation of programs promoting facility births resulted in a rise from 39% in 2005 to 85% in 2014. There have been no reports on bypassing facilities for childbirth from India. In the context of steeply rising facility births, it is important to quantify the occurrence of and study the relative contributions of maternal characteristics and facility functionality to bypassing. Objectives 1) To determine the extent of bypassing health facilities for childbirth among rural mothers in three districts of Gujarat, India, 2) to identify associations between the functionality of an obstetric care (OC) facility and it being bypassed, and 3) to assess the relative contribution of maternal and facility characteristics to bypassing. Design A cross-sectional survey of 166 public and private OC facilities reporting ≥30 births in the 3 months before the survey was conducted in three purposively selected districts (Dahod, Sabarkantha, and Surendranagar) in the state of Gujarat, India. Besides information on each facility, data from 946 women giving birth at these facilities were also gathered. Data were analyzed using a multilevel mixed-effects logistic regression model. Results Off all mothers, 37.7% bypassed their nearest facility for childbirth. After adjusting for maternal characteristics, for every one-unit increase in the facility's emergency obstetric care (EmOC) signal functions, the odds

    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. PMID:22981054

    India has reasons to be concerned about climate change. Over 650 million people depend on climate-sensitive sectors, such as rain-fed agriculture and forestry, for livelihood and over 973 million people are exposed to vector borne malarial parasites. Projection of climatic factors indicates a wider exposure to malaria for the Indian population in the future. If precautionary measures are not taken and development processes are not managed properly some developmental activities, such as hydro-electric dams and irrigation canal systems, may also exacerbate breeding grounds for malaria. This article integrates climate change and developmental variables in articulating a framework for integrated impact assessment and adaptation responses, with malaria incidence in India as a case study. The climate change variables include temperature, rainfall, humidity, extreme events, and other secondary variables. Development variables are income levels, institutional mechanisms to implement preventive measures, infrastructure development that could promote malarial breeding grounds, and other policies. The case study indicates that sustainable development variables may sometimes reduce the adverse impacts on the system due to climate change alone, while it may sometimes also exacerbate these impacts if the development variables are not managed well and therefore they produce a negative impact on the system. The study concludes that well crafted and well managed developmental policies could result in enhanced resilience of communities and systems, and lower health impacts due to climate change.

    Indian agriculture depends heavily on groundwater pumping. These water withdrawals are not all consumed directly by the crops they irrigate; estimated irrigation inefficiencies indicate that two thirds of irrigation water withdrawals in India are 'lost'. Withdrawals lost through leaky canals and flood irrigation systems become runoff and re-enter the surface water system. This mechanism causes irrigation inefficiencies to re-distribute water across basins, and can significantly alter the amount of surface water available both locally and downstream. In this study we used a gridded water balance model to track the path of groundwater from its pumping location, through irrigation systems, and to its downstream consumption or discharge from river mouths. We find that nearly half of all groundwater pumped at rates higher than recharge are re-used downstream. Furthermore, increasing the efficiency of irrigation systems has the potential to decrease surface water levels downstream. We used the water balance model to simulate scenarios of increased irrigation efficiency and find that doubling efficiency does not reduce India's dependence on pumping deep groundwater by half as would be expected from standard measures of irrigation efficiency, but rather by only 38%. Increasing irrigation efficiency to 100% (i.e., no irrigation water losses) causes a decrease in modeled river discharge in both the Indus and the Ganges. The water balance model can also simulate scenarios in which groundwater pumping is limited to recharge rates. In this case, increasing irrigation efficiency to 100% results in a decrease in available surface water across large regions of eastern India, revealing the region's dependence on surface water that was originally sourced from deep groundwater pumping upstream. These results have two important implications. First, they raise questions about the strategy of increasing irrigation efficiency as a strategy for reducing water stress. Second, they show

    Clinical documentation and health information portability pose unique challenges in urban and rural areas of India. This article presents findings of a pilot study conducted in a primary health center in rural India. In this article, we focus on primary care in rural India and how a portable health record system could facilitate the availability of medical information at the point of care. We followed a geriatric cohort and a maternal cohort of 308 participants over a nine-month period. Physician encounters were entered into a web-based electronic health record. This information was made available to all study participants through a short messaging service (SMS). Additionally, 135 randomly selected participants from the cohort were issued a USB-based memory card that contained their detailed health records and could be viewed on most computers. The dual portability model implemented in the pilot study demonstrates the utility of the concept. PMID:25214819

    Cryptococcus neoformans var. grubii and C. gattii were repeatedly isolated from decaying wood of trunk hollows in living trees growing in Jabalpur City in Central India. The isolation of C. gattii has been reported from decayed wood inside trunk hollow of Tamarindus indica (15.6%), Mangifera indica (2.2%), Pithecolobium dulce (12.5%), Syzygium cumini (14%), and one from bark of S. cumini. C. n. var. grubii was isolated from decaying wood debris of T. indica (4.4%), M. indica (13.3%), Terminalia arjuna (25%), S. cumini (2%), Cassia fistula (4.5%), and two from bark of S. cumini. The two species [corrected] never co-occurred in the same hollow. C. gattii [corrected] isolates belonged to serotype B. [corrected] The data strongly supported the colonization of the pathogen in decaying wood hollow of all six-tree species. Evidence of this was found by repeated isolation up to 820 days. P. dulce is being reported for the first time as natural habitat of C. gattii and T. arjuna and C. fistula as natural habitat for C. n. var. grubii. M. indica is being reported for the second time as the natural habitat of both species [corrected] (C. n. var. grubii and C. gattii). The population density of these pathogens from decaying wood debris of various tree species ranged between 0.5 x 10(3) cells/g and 6 x 10(5) cells/g. The seasonal variation has been seen in isolation of these pathogens. [corrected] Our result further reinforce the recently emerging evidence that the natural habitat of C. n. var. grubii and C. gattii is more generalized. PMID:17661160

    Emission inventory of CO 2, CH 4, N 2O and SO 2 has been prepared for Nagpur city in Central India for the year 2004. Data on fossil fuel (coal, light diesel oil, high speed diesel, petrol/gasoline, low sulphur heavy stock, furnace oil and kerosene) consumption in thermal power, industrial, transport and domestic sectors were collected. Thermal power sector had the maximum coal consumption followed by the industrial and domestic sectors, whereas kerosene, liquefied petroleum gas (LPG), diesel and gasoline were used only in any single sector. Total annual CO 2, CH 4, N 2O and SO 2 emissions from these fuels in Nagpur city for the year 2004 was found to be 14792418 MT (14.8 Tg), 4649 (4.6 Tg), 1529 (1.5 Tg) and 69093 (6.9 Tg), respectively, in which thermal power and domestic sector had the maximum share. Coal was found to be the major contributor to Green House Gas (GHG) and SO 2 emissions in all the sectors barring transport and domestic sectors. Carbon dioxide was the predominant GHG emitted by the selected sectors in terms of absolute emissions and also global warming contribution (GWC), though the share in the latter was lesser in magnitude due to higher global warming potential (GWP) of CH 4 and N 2O than CO 2. Thermal power sector had a share of 51% in total CO 2 emissions from all the sectors, followed by domestic, industrial and transport sectors having 27, 12 and 10% contributions, respectively. Share of thermal power sector in total SO 2 emissions was 61%, followed by 24% from industrial, 10% from domestic and 5% from transport sector.

    Using high luminance point-of-light stimuli, Vernier judgments can be made in the presence of markedly degraded retinal imagery. Without coaching, observers perform center-of-gravity assessments of relative locations of degraded point images. We seek to defined, presurgery, individuals who will derive the most benefit from advanced cataract removal (a form of triage), and to determine which of two cataractous eyes has the better postsurgical visual prognosis. There are incredible and growing backlogs of patients with severe cataracts (and other dense media opacities) in the developing world, and generally, limited resources are available for provision of health care. Postcataract surgical failure rates for good visual function are often high, and only one eye is operated on in over 95% of indigent patients treated. Prior to initiating advanced studies in the developing world, at Berkeley we conducted preliminary research on Vernier acuity test techniques on normal adult subjects. We sought to determine the number of repeat trials necessary; to compare a two-point and a three-point Vernier display; to determine the shape of the measured response function at large gap separations between test points (required when testing advanced cataract patients); to assess the effect(s) of a broad range of uncorrected refractive errors on outcomes; and to consider means to minimize refraction-based errors. From these and prior data and analyses, we defined a protocol for use in the developing world. Using a newly designed and rugged precision instrument, these tests were repeated on an advanced cataract population at Aravind Eye Hospital in Madurai, India. Although we had much prior experience in India, the initial protocol required major revision on site. Necessary changes in test methods and analytical approaches were made, and next stages in this program were planned. And a new and simple gap `visual acuity' (gap `VA') test was added to the protocol, which greatly facilitated

    Breast cancer is the leading cause of cancer death among women worldwide especially in a developing country like India. It also occupies the highest place with relative proportion 17.5% in the Hospital Based Cancer Registry in progress in the Dr. B. Borooah Cancer Research Institute. Dr. B. Borooah Cancer Research Institute is the Regional Cancer Care Center for entire North East region of India. With this background a matched case control study of 100 cases of breast cancer and 100 controls was carried out to investigate the role of different Socio economic, Female Reproductive and Life style related factors and to understand the etiology of breast cancer in Assam. Controls are matched to the cases by age at diagnosis (±5 years), family income and place of residence with matching ratio 1:1. Data were collected using questionnaire and then conditional logistic regression analysis is used to estimate the odd ratios for several factors. Study revealed that breast cancer occurrence has statistical association with the factors chewing habits (p=0.003), number of children (p=0.080), age at marriage (p=0.014), age at first child birth (p=0.007), age at menarche (p=0.010).

    Context: Damages and loss of life sustained during an earthquake results from falling structures and flying glass and objects. To address these and other problems, new information technology and systems as a means can improve crisis management and crisis response. The most important factor for managing the crisis depends on our readiness before disasters by useful data. Aims: This study aimed to determine the Earthquake Information Management System (EIMS) in India, Afghanistan and Iran, and describe how we can reduce destruction by EIMS in crisis management. Materials and Methods: This study was an analytical comparison in which data were collected by questionnaire, observation and checklist. The population was EIMS in selected countries. Sources of information were staff in related organizations, scientific documentations and Internet. For data analysis, Criteria Rating Technique, Delphi Technique and descriptive methods were used. Results: Findings showed that EIMS in India (Disaster Information Management System), Afghanistan (Management Information for Natural Disasters) and Iran are decentralized. The Indian state has organized an expert group to inspect issues about disaster decreasing strategy. In Iran, there was no useful and efficient EIMS to evaluate earthquake information. Conclusions: According to outcomes, it is clear that an information system can only influence decisions if it is relevant, reliable and available for the decision-makers in a timely fashion. Therefore, it is necessary to reform and design a model. The model contains responsible organizations and their functions. PMID:23555130

    Of the more than 1.4 million blind children worldwide, 75% live in developing countries. To reduce the prevalence of childhood blindness and associated diseases, attention is given to understanding the perceptions and level of awareness held by caregivers. This understanding can enable tailored health programs to reduce the global prevalence of blindness with increased efficiency. This study, which took place in Ghana, Honduras, and India, found that 95% of caregivers believed in the importance of eye exams for children, yet 66% of caregivers said that none of their children had ever received an eye exam. Participants' major reasons for not bringing their children included the belief that their child had no eye problems along with similar and unique socio-economic barriers. Further information was gained through the use of a five-question test on basic child eye care symptoms, which showed that out of the three country locations, the studied population in India had the least understanding about pediatric eye symptoms. Further analysis revealed significant gaps in understanding of general eye health while detected knowledge barriers provide evidence that fundamental misconceptions appear to be inhibiting caregivers' competence in facilitating their children's eye health.

    In India, most of the diarrhoeal deaths among children (<5 years) are attributed to food and water contamination. Mothers are usually the final line of defence against food borne illnesses. Thus, the role of mothers in ensuring food safety at homes is well accepted. There are hardly any studies in India to understand their knowledge, attitudes and practices on food safety. The present study was an attempt in this direction. A total of 32 Focus Group Discussions were carried out with mothers of children <5 years in 16 districts from all the four South Indian states. The findings reveal that food safety awareness and practices are good among mothers perhaps due to the Indian food ethos passed on to them through generations. Home cooked foods are considered to be safer than prepared foods bought from outside. Many mothers were aware of the common food adulterants but do not bother to complain or take action. There is a need to create enabling environment with improved access to potable water, sanitation and cooking fuel. Spreading awareness about checking food labels and reporting to the health authorities in case of food poisoning or adulteration is also the need of the hour. The Anganwadi Centres can be the focal points for imparting food safety education to the mothers. PMID:17448570

    Background Drowsiness compromises driving ability by reducing alertness and attentiveness, and delayed reaction times. Sleep-related car crashes account for a considerable proportion of accident at the wheel. Narcolepsy type 1 (NT1), narcolepsy type 2 (NT2) and idiopathic hypersomnia (IH) are rare central disorders of hypersomnolence, the most severe causes of sleepiness thus being potential dangerous conditions for both personal and public safety with increasing scientific, social, and political attention. Our main objective was to assess the frequency of recent car crashes in a large cohort of patients affected with well-defined central disorders of hypersomnolence versus subjects from the general population. Methods We performed a cross-sectional study in French reference centres for rare hypersomnia diseases and included 527 patients and 781 healthy subjects. All participants included needed to have a driving license, information available on potential accident events during the last 5 years, and on potential confounders; thus analyses were performed on 282 cases (71 IH, 82 NT2, 129 NT1) and 470 healthy subjects. Results Patients reported more frequently than healthy subjects the occurrence of recent car crashes (in the previous five years), a risk that was confirmed in both treated and untreated subjects at study inclusion (Untreated, OR = 2.21 95%CI = [1.30–3.76], Treated OR = 2.04 95%CI = [1.26–3.30]), as well as in all disease categories, and was modulated by subjective sleepiness level (Epworth scale and naps). Conversely, the risk of car accidents of patients treated for at least 5 years was not different to healthy subjects (OR = 1.23 95%CI = [0.56–2.69]). Main risk factors were analogous in patients and healthy subjects. Conclusion Patients affected with central disorders of hypersomnolence had increased risk of recent car crashes compared to subjects from the general population, a finding potentially reversed by long-term treatment.

    Hemoglobin Eβ thalassemia is a major public health problem in India, especially in the state of West Bengal. Various thromboembolic events are common, especially in splenectomized patients. Platelet hyperactivity most likely plays a pathogenetic role. To investigate the role of platelets in hypercoagulability, platelet aggregation tests were undertaken in the present study. Platelet-rich plasma from 30 patients with Eβ thalassemia (15 splenectomized and 15 nonsplenectomized) were studied and compared with 15 healthy participants. The 4 agonists used were adenosine 5-diphosphate, adrenaline (epinephrine), collagen, and ristocetin. The current study shows both splenectomized and nonsplenectomized patients had abnormal aggregation compared to normal healthy controls. Splenectomized patients had higher platelet aggregation than nonsplenectomized patients for all 4 agonists; but statistically significant difference among 2 groups was found only for collagen. The present study confirms a role of splenic absence in platelet hyperaggregation. PMID:25701765

    Recent remote sensing studies have documented a greening trend in the semi-arid Sahel and Sudan zones of West Africa since the early 1980s, which challenges the mainstream paradigm of irreversible land degradation in this region. What the greening trend means on the ground, however, has not yet been explored. This research focuses on a region in central Senegal to examine changes in woody vegetation abundance and composition in selected sites by means of a botanical inventory of woody vegetation species, repeat photography, and perceptions of local land users. Despite the greening, an impoverishment of the woody vegetation cover was observed in the studied sites, indicated by an overall reduction in woody species richness, a loss of large trees, an increasing dominance of shrubs, and a shift towards more arid-tolerant, Sahelian species since 1983. Thus, interpretation of the satellite-derived greening trend as an improvement or recovery is not always justified. The case of central Senegal represents only one of several possible pathways of greening throughout the region, all of which result in similar satellite-derived greening signals.

    An attempt was made to assess the impact of climate change on the crop productivity of sorghum [Sorghum bicolor (L.) Moench] in India. Climate change scenarios were projected for three sorghum growing areas in India using three global climate models (GCMs) namely; Goddard Institute of Space Studies (GISS), Geophysical Fluid Dynamics Laboratory (GFDL), and United Kingdom Meteorology Office (UKMO). The three diverse sorghum growing areas selected were Hyderabad, Akola, and Solapur. In the first two regions sorghum is grown in the rainy season, whereas in the third region it is grown in the post rainy season. Crop growth was simulated using the CERES-sorghum simulation model with climate change scenarios generated by the GCMs. The simulations were run with and without the direct effects of doubled atmospheric CO{sub 2} levels, under dryland, low N conditions, and under nonlimiting water and nutrient conditions. The simulated results indicated a decrease in yield and biomass of rainy season sorghum at Hyderabad and Akola under all climate change scenarios. Post rainy season sorghum grown at Solapur on stored soil water showed a marginal increase in yield. The positive effects of increased CO{sub 2}, if any, were masked by the adverse effects of predicted increase in temperature resulting in shortened crop growing seasons.

    Large number of epidemiological studies to know the effect of air pollution on the general mortality and morbidity, and the cardiopulmonary morbidity and mortality are concentrated in USA and Europe. Regional differences in air pollution necessitate regional level health effects studies. Present study is a cross sectional pilot study from India, an Asian country. A sample of population from an industrial town ‘Mandi Gobindgarh’ and a non-industrial town ‘Morinda’ were selected. A cross-sectional household survey was done in both the towns. One hundred subjects were selected from each of the towns. Ambient air quality data was collected for both towns over a period of 10-months to assess seasonal variations. In the present study the average PM10 (particulate matter with ≤ 10μm aerodynamic diameter) levels in Morinda were 99.54 μg/m3 and in Mandi Gobindgarh 161.20 μg/m3. As per NAAQS the permitted levels of PM10 is 50 μg/m3 taken as annual average (arithmetic mean). Elemental analysis of the aerosol samples found the concentration levels to be higher in Mandi- Gobindgarh than Morinda. The population in Gobindgarh shows a higher prevalence of symptoms of angina and cardiovascular disease considered in the study as compared to Morinda. When the same data is viewed in terms of male and female population, the female population is found to show these symptoms marginally higher than their counterparts. Considering the results of present study it can be stated that the increased levels of different pollutants and the higher prevalence of cardiovascular symptoms in Mandi-Gobindgarh (Industrial town) than the Morinda (Non-Industrial town) is because of the association of PM pollution with cardiovascular diseases. Keeping in view the current status of literature, further studies in this direction are needed in a country like India. Such data will also be globally relevant. PMID:18180537

    Estuarine sediments are major reservoirs for the metals. Distribution and mobility of metals within estuaries depends strongly on their specific chemical form. In the present study, surface sediments from Zuari estuary, Goa were analysed by a sequential procedure for Fe, Mn, Cu, Zn, Cr and Co to determine their distribution in five geochemical phases (Exchangeable, carbonate, Fe-Mn oxide (reducible) organic bound (oxidisable) and residual). The total metal content, sand, silt, clay and organic carbon were also determined of the surface sediments. The total metal contents were found to be greater than the background concentrations of average shale values as well as to that of earlier studies indicating enrichment probably due to the anthropogenic origin of metals. The results obtained from sequential procedure showed that among the studied elements, Mn and Co are potentially available in the bioavailable fractions (exchangeable, carbonate and Fe-Mn oxide bound fractions) indicating their importance in toxicity whereas rest of the metals viz. Fe, Cu, Zn and to some extent Cr are largely available in residual phase although they are available in other fractions. The main source of metals to the estuary is mining and its associated activities in the study area. Chemical speciation by sequential extraction procedure has helped in assessing the mobility, bioavailability, diagenesis and toxicity of metals and hence giving a better insight into the ultimate fate of pollutants, which are introduced into the estuarine environment. To understand the risk of the metals to the sediment dwelling organisms the data were compared with the Sediment Quality Values (SQV) using SQUIRT. Also, correlation and Factor analysis were carried out to understand the associations of metals in the different fractions with sand, silt, clay, organic carbon and with other metals. PMID:18946719

    The present study was performed to identify and validate monogenean species from different piscine hosts using molecular tools. Nine species of freshwater monogeneans were collected from gills and skin of freshwater fishes at Hastinapur, Meerut, India. After microscopic examination, molecular analysis was performed utilizing 28S gene marker. Phylogenetic analysis indicated the validation and systematic position of these nine different monogeneans belongs to the Dactylogyridae and Gyrodactylidae families. The findings also confirm that the 28S rDNA sequence is highly conserved and may prove to be useful in taxonomic studies of parasitic platyhelminthes. Besides this, the study is also supplemented by molecular morphometrics that is based on 28S secondary structure homologies of nine monogenean species. The data indicate that 28S motifs i.e., ≤ 50bp in size can also be considered a promising tool for monogenean species identification and their validation. PMID:23144541

    Although some studies suggested specific foods/beverages as risk factors for travellers' diarrhoea (TD), details of transmission remain unclear. We assessed the influence of travel style (luxury/middle-class versus backpacking) on TD risk. TD attack rates were compared in a prospective study among travellers to India at the University of Zurich's Travel Clinic. Information on consumption of foods/beverages was collected. Seventy-one luxury/middle-class travellers and 21 backpackers completed the study; overall 37% suffered from TD (62% backpackers, 30% luxury/middle-class travellers, OR 4.43, p 0.022). Travel style rather than the consumption of specific foods/beverages appears to be a risk factor for TD development. PMID:25882361

    This paper compares the desired fertility of rural Indian women in 1987 with their actual fertility in 2007. Seventy-one respondents who stated definite fertility intentions and had fewer children than desired in 1987 were re-interviewed 20 years later, as part of a larger study. The results indicated that these women had fewer children than intended and stopped childbearing once they reached, or approximated, their desired number of sons. The majority had been sterilized, indicating broad acceptance of lower fertility among rural women and the success of India's family planning efforts, although the practice of sex determination seems also to have played a role. These findings echo those of an earlier longitudinal study of reproductive intentions and outcomes in the same community, demonstrating the persistence of son preference in determining reproductive behaviour, even in the context of low overall fertility. The paper concludes with a discussion of the policy and programme implications of the study's findings. PMID:22047888

    In mountainous region with heterogeneous topography, the geostatistical modeling of the rainfall using global data set may not confirm to the intrinsic hypothesis of stationarity. This study was focused on improving the precision of the interpolated rainfall maps by spatial stratification in complex terrain. Predictions of the normal annual rainfall data were carried out by ordinary kriging, universal kriging, and co-kriging, using 80-point observations in the Indian Himalayas extending over an area of 53,484 km2. A two-step spatial clustering approach is proposed. In the first step, the study area was delineated into two regions namely lowland and upland based on the elevation derived from the digital elevation model. The delineation was based on the natural break classification method. In the next step, the rainfall data was clustered into two groups based on its spatial location in lowland or upland. The terrain ruggedness index (TRI) was incorporated as a co-variable in co-kriging interpolation algorithm. The precision of the kriged and co-kriged maps was assessed by two accuracy measures, root mean square error and Chatfield's percent better. It was observed that the stratification of rainfall data resulted in 5-20 % of increase in the performance efficiency of interpolation methods. Co-kriging outperformed the kriging models at annual and seasonal scale. The result illustrates that the stratification of the study area improves the stationarity characteristic of the point data, thus enhancing the precision of the interpolated rainfall maps derived using geostatistical methods.

    The evidence from studies of central nervous system serotonin (5-HT) receptors is reviewed and the role of these in the pathogenesis of mood disorders is discussed. Clinical evidence indicates that 5-HT function is abnormal in mood disorders. 5-HT precursors and selective inhibitors of 5-HT uptake are effective antidepressives and inhibition of 5-HT synthesis can block the action of antidepressives. Studies of 5-HT in experimental animals after chronic administration of antidepressive treatments suggest that intact 5-HT neurons are necessary for the action of these treatments. Multiple 5-HT receptor subtypes have recently been identified and the effects of chronic antidepressive treatment on some receptor subtypes function in experimental animals have been established. The increasing availability of powerful new in vivo imaging techniques like single photon emission tomography (SPET), and positron emission tomography (PET) may make possible a more direct examination of 5-HT receptor function in patients suffering from mood disorders.

    The sedimentary beds associated with Deccan Continental Flood Basalt (DCFB) sequences exposed in the volcanic subprovinces of Jabalpur-Mandla-Chhindwara (JMC) regions of Madhya Pradesh and Nand-Dongargaon (N-D) basin and the adjoining areas to the west in Yeotmal-Nanded in Maharashtra were studied for their palynofloral analysis. The sediments were characterized palynologically and changes in the palynoflora are observed at different stratigraphic levels in a number of sections including several new intertrappean localities recorded in recent years. For the purpose of effective correlation of different subprovinces, palynofloras of some of the previously studied intertrappeans are also reviewed. Our studies suggest that before the start of the Deccan volcanic activity, the palynoflora found in the Lameta sediments, was dominated by gymnosperms-angiosperm association. The plant canopy consisted mainly of gymnosperms (Conifers and Podocarpaceae) whereas, the understory members were mostly of palms and herbs (Poaceae and Asteraceae). The eruption of Deccan volcanic flows severely affected the existing floral association and proved fatal for the well established plant community. The immediately overlying sediments associated with the earliest volcanic flows are dominated by pteridophytes and angiosperm taxa (Azolla cretacea, Aquilapollenites bengalensis, Ariadnaesporites sp., Gabonisporis vigourouxii and Triporoletes reticulatus). Higher up in the stratigraphic sequence, similar forms continued with simultaneous appearance of new taxa including Scabrastephanocolpites spp. At still higher stratigraphic levels, abundance of fungi especially the mycorrhizal fungi, concurrent with sharp decline in pollen/spore recovery was observed. In the culminating phase (i.e. Palaeocene) of Deccan volcanic history a new palynofloral assemblage of typical Palaeocene taxa (Dandotiaspora dilata, D. pseudoauriculata, D. plicata, Spinizonocolpites echinatus, Matanomadhiasulcites sp., and

    Pollination and reproductive biology of a dioecious tree Canarium strictum Roxb. (Burseraceae) was extensively studied within the Agumbe forest range of Western Ghats, Karnataka to identify primary pollen vectors and to enumerate interrelationship with the pollinators. The study also investigated phenology, floral biology, pollen production, pollen viability, stigma receptivity and nectar production. Trees produced functionally unisexual flowers with white petals, organized densely on inflorescences. Staminate flowers produced high percentage of viable pollen and relatively abundant nectar (15.75 μl) as a reward to the pollinators, while pistillate flowers produced only nectar (12 μl). Successful fruit set with wind pollination was facilitated by synchronization of flowering male and female trees, long term receptivity of stigma in female flowers and extended lifespan of flowers. The highest mean percent of fruit set with hand cross-pollination (μ = 91.06) suggests the influence of local male tree density, as well as, frequency and abundance of pollinator community on fruit set by open pollination.

    Superficial lesion with central depression obtained by endoscopic resection (23 carcinomas limited in the mucosa and 40 adenomas) were studied morphologically and histologically. These lesions were calculated concerning the height from the muscularis mucosa, depth of depressed central portions and the height of circumferential mucosa. Then, using the image analyzer, followings were determined with two-dimensional analysis: (1) the size of neoplasms and also (2) the size of whole mucosal lesions which was calculated by drawing a perpendicular from the border of the neoplasms; and thus, the ratio of each area was calculated. Little difference was found between the adenomas and carcinomas. The sizes of carcinomas were found to be of 8.8 ± 4.7 mm and the adenomas of 5.1 ± 2.3 mm (p < 0.01). As for the depth of depression, it was found to be of 352 ± 147 μm in the carcinomas and 277 ± 93 μm in the adenomas (p < 0.05). Concerning the ratio of carcinomatous area in the mucosa, it was found to be 78 ± 10% in the carcinomas, while in the adenomas, it was found to be 70 ± 10% (p < 0.05). Accordingly, it was found that compared with the adenomas, carcinomas showed significantly larger in size, deeper depression in configuration and the ratio of their size in the mucosa is rather high.

    Aerosol plays an important role in modulating solar radiation, which are of great concern in perspective of regional climate change. The study analysed the physical and optical properties of aerosols over an urban area and estimated radiative effect using three years in-situ data from sunphotometer, aethalometer and nephelometer as input to radiative transfer model. Aerosols properties indicate the dominance of fine mode aerosols over the study area. However presence of coarse mode aerosols is also found during pre-monsoon [March-April-May]. Daily mean aerosol optical depth showed a minimum during winter [Dec-Jan-Feb] (0.45-0.52) and a maximum during pre-monsoon (0.6-0.7), while single scattering albedo (ω) attains its maximum (0.78 ± 0.05) in winter and minimum (0.67 ± 0.06) during pre-monsoon and asymmetry factor varied in the range between 0.48 ± 0.02 to 0.53 ± 0.04. Episodic events of dust storm and biomass burning are identified by analyzing intrinsic aerosol optical properties like scattering Ångström exponent (SAE) and absorption Ångström exponent (AAE) during the study periods and it has been observed that during dust storm events ω is lower (∼0.77) than that of during biomass burning (∼0.81). The aerosol direct radiative effect at top of the atmosphere during winter is -11.72 ± 3.5 Wm-2, while during pre-monsoon; it is -5.5 ± 2.5 Wm-2, which can be due to observed lower values of ω during pre-monsoon. A large positive enhancement of atmospheric effect of ∼50.53 Wm-2 is observed during pre-monsoon compared to winter. Due to high aerosol loading in pre-monsoon, a twofold negative surface forcing is also observed in comparison to winter.

    This bottom-up modeling study, supported by emission inventories and crop production, simulates ozone on local to regional scales. It quantifies, for the first time, potential impact of ozone on district-wise cotton, soybeans, rice, and wheat crops in India for the first decade of the 21st century. Wheat is the most impacted crop with losses of 3.5 ± 0.8 million tons (Mt), followed by rice at 2.1 ± 0.8 Mt, with the losses concentrated in central and north India. On the national scale, this loss is about 9.2% of the cereals required every year (61.2 Mt) under the provision of the recently implemented National Food Security Bill (in 2013) by the Government of India. The nationally aggregated yield loss is sufficient to feed about 94 million people living below poverty line in India.

    Background The incidence of gastric cancer varies in different parts of the world and among various ethnic groups. It remains the fifth most common cancer among males and seventh most common cancer among females in India. Materials and methods We conducted a retrospective study using the data base of 158 patients of primary gastric cancer diagnosed in the Department of Surgery at Regional Cancer Centre, RIMS, Manipur, India from July 2009 to June 2013. Results Our study revealed a male to female ratio of 2.16:1, distribution of age varied from 28 to 91 years. Majority of the men were in the age group of more than 60 years (45.37%) and majority of females were of 51-60 years (44%). Nearly 7.6% patients had a positive family history. Dietary history of intake salted, fermented fish was present in 67.7% of patients, whereas history of consumption of smoked meat was found in 77.8% of patients. Only 27.8% of patients in our study had history of regular consumption of fresh fruits. About 35.4% of the patients had poor drinking water source. Nearly, 67.6% of males and 44% of females had smoking history. Combined consumption of alcohol and smoking was present in 33.5% of patients. Vague abdominal discomfort was the most common presenting symptom in 61.4% of patients. The most common site of gastric cancer in our study was antrum (50.6%) followed by cardia (17.1%). The most common histological type was adenocarcinoma (95.6%). Most of our patients presented in locally advanced stage (62.7%). Conclusions Our analysis suggests that poor dietary habits such as smoked mead, dried fish and excessive use of tobacco are associated with high occurrence of gastric cancer in this part of the India. Increasing the awareness regarding the aetiology and varied clinical presentation among general population and health providers is needed for prevention and early detection. PMID:24772342

    . The ubiquitous transformation of land into the high-intensity agro-industrial production system has now reached marginal land formerly unsuitable for agriculture: Badland areas and wasteland dissected by gully erosion are being levelled with heavy machinery. However, these measures are often contra-productive. Levelled sites show a clear amplification of soil erosion processes, and temporarily infilled gullies tend to be re-activated very fast, eroding this freshly provided soil material. As a first step in a comparative investigation of the sustainability of land reclamation measures in erosive landscapes with contrasting situations, data derived from remote sensing (satellite and unmanned aerial vehicle images) as well as socio-economic surveys were used for establishing an inventory on the two regions in South Morocco and Central India. The long-term aim is the development of a framework for further research into the positive and negative influences of land-levelling as a gully-erosion control measure.

    Palynology, texture, mineralogy, geochemistry, and magnetic susceptibility analysis of a 2 m deep sediment core from Padauna Swamp, southeastern Madhya Pradesh infers that between 8600 and 7500 cal yr BP a warm and relatively less-humid climate prevailed with open tree-savannahs dominated by grasses followed by sedges, Artemisia and members of Chenopodiaceae/Amaranthaceae with scanty trees viz., Schrebera, Aegle marmelos and Sterculia urens. This is well supported by lower organic to carbonate carbon ratio, coarser texture having relatively low CIA and magnetic susceptibility values and presence of some primary minerals. Between 7500 and 6250 cal yr BP the tree-savannahs were succeeded by open mixed deciduous forests with the invasion of a few more trees viz., Madhuca indica, Holoptelea, Emblica officinalis, Mitragyna parvifolia and members of Anacardiaceae in response to onset of a warm and humid climate. A considerable rise in organic carbon generated from the degradation of plentiful biomass along with increase in clay content with signs of kaolinite and increase in immobile over mobile elements with slightly higher CIA and magnetic susceptibility values also suggest climatic amelioration. The presence of ruderal plants such as Artemisia, Cannabis sativa and Cheno/Am further infers initiation of human activities in the region. Between 6250 and 2800 cal yr BP, the mixed deciduous forests became more diverse and dense, subduing grasses and other herbaceous elements. Sporadic incursion of Shorea robusta (Sal) in forest floristic was recorded around 5000 cal yr BP. The overall change in the vegetation mosaic reflects that a warm and more-humid climate prevailed in the region, probably on account of invigoration of southwest monsoon. This observation is further corroborated by other proxy data showing a spurt in organic/inorganic carbon ratio, increase in clay content with matured mineralogy, significantly higher CIA and magnetic susceptibility values. Since 2800 cal yr BP onwards, the modern Sal dominated deciduous forests were established indicating continuation of warm and more-humid climate including timely arrival of SW monsoon coinciding with the shedding of Sal seeds as they are viable for a very short period.

    Objectives Atrial fibrillation (AF) is the most common sustained arrhythmia encountered in clinical practice with major public health impact mainly due to the increased risk of stroke. The recent Global Burden of Disease Study reported a lack of prevalence data from India. Our goal was to conduct a pilot study to evaluate the feasibility of assessing AF prevalence and stroke prophylaxis in an urban Indian community. Methods A screening camp was conducted in Nagpur, India, that evaluated adults aged ≥18 years. We collected demographics, recorded blood pressure, height, weight and the 12-lead electrocardiogram (ECG). The presence of diabetes and hypertension was recorded by self-reported history. Patients diagnosed with AF were evaluated further to assess aetiology and management. Results Of the total 4077 randomly selected, community-dwelling adults studied, 0.196% (eight patients) were found to have AF. Mean age of the population was 43.9±14.8, and 44.5% were female. The mean age of the patients with AF was 60.5±15.8 years (five females). Rheumatic heart disease was found in five patients with AF. Three patients had history of stroke (37.5%) and one had peripheral arterial thrombosis. Three patients were on warfarin, but without routine international normalised ratio (INR) monitoring. One patient was on aspirin. Five patients were on β-blockers and one on both β-blocker and digoxin. Conclusions The prevalence of AF was low compared with other regions of the world and stroke prophylaxis was underused. A larger study is needed to confirm these findings. This study demonstrates that larger evaluations would be feasible using the community-based techniques employed here. PMID:27326234

    Objective Clinical studies demonstrate the efficacy of interventions to reduce neonatal deaths, but there are fewer studies of their real-life effectiveness. In India, women often seek facility delivery after complications arise, rather than to avoid complications. Our objective was to quantify the association of facility delivery and postnatal checkups with neonatal mortality while examining the “reverse causality” in which the mothers deliver at a health facility due to adverse perinatal events. Methods We conducted nationally representative case-control studies of about 300,000 live births and 4,000 neonatal deaths to examine the effect of, place of delivery and postnatal checkup on neonatal mortality. We compared neonatal deaths to all live births and to a subset of live births reporting excessive bleeding or obstructed labour that were more comparable to cases in seeking care. Findings In the larger study of 2004–8 births, facility delivery without postnatal checkup was associated with an increased odds of neonatal death (Odds ratio = 2.5; 99% CI 2.2–2.9), especially for early versus late neonatal deaths. However, use of more comparable controls showed marked attenuation (Odds ratio = 0.5; 0.4–0.5). Facility delivery with postnatal checkup was associated with reduced odds of neonatal death. Excess risks were attenuated in the earlier study of 2001–4 births. Conclusion The combined effect of facility deliveries with postnatal checks ups is substantially higher than just facility delivery alone. Evaluation of the real-life effectiveness of interventions to reduce child and maternal deaths need to consider reverse causality. If these associations are causal, facility delivery with postnatal check up could avoid about 1/3 of all neonatal deaths in India (~100,000/year). PMID:26479476

    Introduction Headache is one of the most common presenting complaints in day to day medical practice however the secondary causes of headache are uncommon. Thus, appropriate selection of headache patient (Pt) is important to determine those that require neuroimaging due to likely secondary cause. Red flags and Clinical warning criterion (CWC) act as a screening tool to help in identifying those who may get benefit from neuroimaging. Aim To evaluate the findings of computed tomography (CT) and Magnetic Resonance Imaging (MRI) among patients presented with the chief complaint of headache and to compare the findings between two groups of patients. Materials and Methods This retrospective observational study was carried out in 500 selected patients, who underwent CT or MRI scan of head in Peoples College of Medical Sciences and Research centre, Bhopal, MP during the period of 2 year in between Jan 2013 to Dec 2014. Siemens Somatom sensation 40 slice MDCT and Siemens magnetom 1.5T MRI scanner were used for imaging. Five hundred patients of 10 to 70 year age were selected for the study based on our criterions of selection. Results All 500 patients were divided in to two groups A and B based on presence or absence of red flag signs and CWC signs. Group A consists of 48 patients having one or more red flag or CWC signs and group B consists of 452 patients those don’t have any above signs. 29 cases (60.4%) out of total 48 cases of group A is suffering from chronic headache as compared to 97 cases (21.5%) out of total 452 patients of group B is having positive findings (p-value<0.05). Out of 500 patients, only 29 cases (5.8%) revealed some form of brain parenchymal pathology whereas other associated findings were seen in 97 cases e.g. sinusitis in 58 (11.6%), bone related pathology in 26 (5.2%) and chronic suppurative otitis media (CSOM) in 13 (2.6%) patients. Conclusion CT/MRI in patients without red flag or CWC sign yields very low percentage of clinically significant

    Background: The use of central venous catheters (CVCs) has greatly improved the quality-of-care in cancer patients, yet these catheters may cause serious infectious and thrombotic complications. The aim of this retrospective study was to study the various types of CVCs and their complications. Materials and Methods: We studied retrospectively 213 cases of CVCs in our institute with their indications, type and complications from August 2010 to July 2011. Results: A total of 213 CVCs were inserted in patients with hematological (62%) and solid organ malignancies (38%). Ninety-eight patients (46%) had peripheral inserted central catheter (PICC), 90 (42%) patients had Hickman catheters and 25 (12%) had a port. The median duration of retention of Hickman catheters was 104 days (3-365 days), for the peripherally inserted central catheters was 59 days (3-100 days) and for the port it was 280 days (45-365 days). Non-infective complications were more than infective (12% vs. 7%). The most common complication was non-infective occlusion and thrombophlebitis. In one patient with PICC thrombosis occurred in the cephalic, radial and ulnar vein and in one patient with port thrombosis occurred in the superior vena cava. Organisms were isolated in 60% (12 out of 20) of cultures. Common organisms isolated were Pseudomonas aeruginosa in 5 (42%), Staphylococcus aureus in 2 (16%), Escherichia coli in 2 (16%) and Aspergillus in 3 (25%) patients. 7 out of 12 infected patients had negative blood cultures within 7 days of antibiotic treatment, 5 patients remained positive for more than 7 days with antibiotics. In 155 patients (73%), the desired treatment protocol was completed and at present there are still 28 patients (13%) with catheters. 5 patients (2.3%) died of febrile neutropenia and septicemia with multi-organ failure. In 5 patients (2.3%), the catheters (1 Port, 1 Hickman and 3 PICC) were prematurely removed because of thrombosis. Conclusion: CVCs are better options to facilitate

    Athletes anticipatorily set and continuously adjust pacing strategies before and during events to produce optimal performance. Self-regulation ensures maximal effort is exerted in correspondence with the end point of exercise, while preventing physiological changes that are detrimental and disruptive to homeostatic control. The integration of feedforward and feedback information, together with the proposed brain's performance modifiers is said to be fundamental to this anticipatory and continuous regulation of exercise. The manipulation of central, regulatory internal and external stimuli has been a key focus within deception research, attempting to influence the self-regulation of exercise and induce improvements in performance. Methods of manipulating performance modifiers such as unknown task end point, deceived duration or intensity feedback, self-belief, or previous experience create a challenge within research, as although they contextualize theoretical propositions, there are few ecological and practical approaches which integrate theory with practice. In addition, the different methods and measures demonstrated in manipulation studies have produced inconsistent results. This review examines and critically evaluates the current methods of how specific centrally controlled performance modifiers have been manipulated, within previous deception studies. From the 31 studies reviewed, 10 reported positive effects on performance, encouraging future investigations to explore the mechanisms responsible for influencing pacing and consequently how deceptive approaches can further facilitate performance. The review acts to discuss the use of expectation manipulation not only to examine which methods of deception are successful in facilitating performance but also to understand further the key components used in the regulation of exercise and performance.

    The aim of the study is to understand the wind pattern over the Peninsular India with the modification of Orography over the region using Regional climate model. The model used in this study is the recent version (Version III) of the National Centre for Atmospheric Research (NCAR) Regional Climate Model RegCM3. The model integration is done on a horizontal resolution of 60 km. . The planetary boundary layer scheme used is that of Holtslag, cumulus parameterization scheme Emanuel of MIT, SUBEX large scale precipitation scheme and BATS ocean flux parameterization scheme. The model is run from 1st May to 30th September. The first month is taken for the spin up. The next four months are taken to study the monsoon. The simulation has been carried out for the 100%, 90%, 60% and 30% Orography (hereafter 100%o,90%o, 60%o, and 30%o) cases with RegCM3. The Zonal wind pattern for the 100%o and 90%o are similar, whereas the pattern changed for the 60% and 30%o. For the 60% and 30%o cases, the Zonal wind strengthened over the south peninsular India gradually increasing towards north. The Meridional component of the wind has a maximum over the Western Ghats between the latitudes 10o N and 15o N for the 100%o. Similar pattern has been observed for the 90%o also. For the 60%o and 30%o, the core has shifted to the northeast of India. The magnitude has decreased for the 30%o and the magnitude of meridional component is zero over the region south of 10o N. Keywords: Orography, Zonal and Meridional wind. References: Giorgi F, Mon. Wea Rev. 121: 2794 (1993) Giorgi F, Marinucci M R and Bates G T , Mon. Wea Rev. 121: 2794 (1993) K. C.

    Background and Aims: This study was undertaken, to assess the clinical parameters in patients of poisonous snakebite, complications which occurred in them, their outcome and to evaluate various clinical predictors of mortality Materials and Methods: Four hundred and thirty-two patients of snake bite were admitted, of which 172 did not show any signs of envenomation and excluded. Two hundred and sixty patients had signs of local or systemic envenomation and included. Complete clinical examination, blood counts, kidney function tests, serum electrolytes, coagulation profile was done in all patients. All received tetanus toxoid and anti-snake venom (ASV). Appropriate supportive treatment was given. Clinical and laboratory parameters were compared between patients who were discharged (Group A) and those who expired (Group B). All data analysis was performed by using stata software version 10 [StataCorp LP, Texas, USA] and SPSS version 11 [SPSS Inc, Chicago, USA]. Results: Out of 260 patients, 58 died and 202 survived. Mean age was 34.97 ± 14.07 years. One hundred and eighty-six (71.5%) patients were from rural areas and 74 (28.5%) from urban. 63.4% of bites occurred during rainy season. One hundred and ninety-seven (75.8%) had bite on lower limb and 62 (23.8%) on upper limbs. All 260 patients (100%) had pain at site of bite, local swelling in 252 (96.9%) and blackening of skin, blebs in 18 (6.9%). Seventy-seven (29.6%) had bleeding tendencies. Ptosis was present in all the 65 patients with signs of neuroparalysis. Eighty (30.8%) patients had acute renal failure. The mean duration of stay in survivors was 7.50 + 4.13 days and in non-survivors it was 3.45 + 3.02 days. Out of 58 who died 18 (31%) patients, succumbed within 24 hrs. On multivariate analysis, significant predictors o mortality were bleeding tendency (P = 0.013), mean PTTK (sec) (P = 0.047), respiratory failure (P = 0.045), shock (P = 0.013), mean ASV dose (cc) (P < 0.001).

    Background: Infectious diarrhea causes a major health problem in developing countries with significant morbidity and mortality. Very often, rehydration therapy alone does not suffice, mandating the use of antimicrobial agents. However, rapidly decreasing antimicrobial susceptibility is complicating the matters. Materials and Methods: The study aimed to determine the prevalent bacterial and parasitic agents of diarrhea in India. A cross-sectional study was done at Maulana Azad Medical College and associated Lok Nayak Hospital, New Delhi, during 2012-14. Stool samples were received from patients of all age groups and processed for bacteriological and parasitological identification by microscopy, bacterial culture, biochemical identification, serotyping and antimicrobial susceptibility tests. The study also aimed to identify the recent papers (after year 2000) reporting aetiology of infectious diarrhea in India involving the general population as a whole and compare them with present findings. Results: Out of 6527 samples, 581 (8.90%) were positive for bacterial pathogens. A total of 280 samples (of 3823 under-five year children) were positive for diarrheagenic Escherichia coli. Other organisms like Vibrio cholera were found in 159 (2.44%) cases, Shigella spp. in 126 (1.93%), Salmonella Typhi in 7 (0.11%), Salmonella Typhimurium in 6 (0.10%), Aeromonas hydrophila in 3 (0.05%) cases. Levels of resistance to nalidixic acid, amoxicillin and ciprofloxacin were alarmingly high. Third generation cephalosporins were seen to be moderately active except against E. coli. Parasites were identified in 312 (4.78%) cases. Giardia intestinalis, Ascaris lumbricoides and Entamoeba histolytica were identified in 2.27%, 1.15% and 0.64% cases respectively. Conclusion: Analysis of recent nationwide studies revealed V. cholerae was the most common bacterial/parasitic agent of diarrhea across all populations, being followed by diarrheagenic E. coli and Giardia intestinalis.

    Urban areas being economically diversified attract large streams of migrants making for a burgeoning population. This is more prevalent in the developing countries. The concomitants of this are high density, heavy traffic movement and increased pollution levels. To reduce the stressful life of city dwellers it is important to have open spaces, where one can pursue leisure time activities a few removes from clutter. A public space is a space that is generally open and accessible to people. Roads, public parks, libraries etc, are typically considered public space. The term ‘public space’ is also often misconstrued to mean other things such as ‘gathering place’, which is an element of the larger concept of social space. Hyderabad, the historical city is the capital of Telangana, India and extends from longitude 78o23’ to 78o33’E and latitude of 17o17’ to 17o31’N. It is the second largest city in terms of area and fifth largest in terms of population. It is one of the fastest growing cities in India. There is a huge influx of people from other states in search of better opportunities. The main objectives of the study are; to study the sprawl and changing demographic structure of the city of Hyderabad, to study the accessibility of parks, to study the need for the emergence of a local public sphere. The data base will be mainly on secondary data collected from various government sources. A primary survey will be conducted based on a structured questionnaire. GIS and other mapping techniques will be applied to analyse the data.

    Background: The production of silk is a multidimensional and multistep process involving exposure of workers to allergens at work place. The silk allergen has been implicated in the development of bronchial asthma. Objectives: To identify the prevalence of occupational asthma (OA) and to identify sensitization to silk allergen and among workers in silk filature units. Materials and Methods: A community-based cross-sectional study was conducted in silk filature units of Ramanagara (Silk City) in Karnataka, South India, for a period of 6 months. One hundred and twenty workers of silk filature units who met the inclusion and exclusion criteria were recruited into the study group. For comparison, a control group comprising of 120 individuals not working in silk filature units was constituted. All the subjects were interviewed using the standardized International Union against Tuberculosis and Lung Diseases (IUATLD) Questionnaire and subjected to the skin prick test, which used the extracts of silk allergen. Results: The study group comprised of 35 males and 85 females, whereas the control group comprised of 58 males and 62 females. The prevalence of occupational asthma among workers in silk filatures was 20.83%. It was observed that 35.83% of those in the study group and 20.83% of those in the control group were found to be sensitive to silk allergen. This difference was statistically significant (χ2= 6.64; P < 0.05). Conclusion: There is a high burden of sensitization to silk allergen and occupational asthma among silk filature workers in South India. PMID:25568600

    High resolution δ18O and δ13C data from absolutely dated stalagmites have been useful for reconstructing the Asian monsoon variability (e.g., Yadava et al., 2004; Laskar et al., 2013; Allu et al., 2014; Lone et al., 2014; Sinha et al., 2015). However, many studies lack high resolution spatial and temporal records leaving significant gaps which need to be filled for a vivid understanding of monsoonal variability. We report here the first high resolution stalagmite δ18O isotope results during the last deglacial obtained from the Kailash cave located from the core monsoon region. The length of stalagmite was 480 mm, with an average diameter of 120 mm. The sample was cut for continuous micro milling at 400μm intervals along the growth axis (using new wave research micro-mill-101288) for the analyses of stable oxygen and carbon isotopes using a Delta V plus IRMS at the Physical Research Laboratory, Ahmedabad. The physical appearance of the sample section reveals very fine, straight and clear laminations from the top to 310 mm from below, which have thick laminae. U-Th dates obtained from a Thermo Fisher NEPTUNE multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS) at High-Precision Mass Spectrometry and Environment Change Laboratory (HISPEC), National Taiwan University, Taiwan (Shen et al., 2012) showed the record spanned ~2400 years from ~14.6 ka to ~12.2 ka. Linear Age-Depth model constructed from dates suggests that the sample grew for ~2.400 years from ~14.6 ka to ~12.2 ka with varying resolutions from ~6 months to ~8 years. Hendy's test from 8 distinct layers shows poor correlation between δ18O and δ13C suggesting the isotopic equilibrium conditions at the time of crystallization. δ18O and δ13C results appear to be cyclic in nature varying in the range from +0.37‰ to -6.07‰ and -1.59‰ to -10.59‰ respectively. Enriched δ18O in top portion represents poor monsoon during the onset of Younger Drayas. Later, the δ18O signals

    Deformational, metamorphic, monazite age and fabric data from Rengali Province, eastern India converge towards a multi-scale transpressional deformational episode at ca. 498-521 Ma which is linked with the latest phase of tectonic processes operative at proto-India-Antarctica join. Detailed sector wise study on mutual overprinting relationships of macro-to microstructural elements suggest that deformation was regionally partitioned into fold-thrust dominated shortening zones alternating with zones of dominant transcurrent deformation bounded between the thrust sense Barkot Shear Zone in the north and the dextral Kerajang Fault Zone in the south. The strain partitioned zones are further restricted between two regional transverse shear zones, the sinistral Riamol Shear Zone in the west and the dextral Akul Fault Zone in the east which are interpreted as synthetic R and antithetic R' Riedel shear plane, respectively. The overall structural disposition has been interpreted as a positive flower structure bounded between the longitudinal and transverse faults with vertical extrusion and symmetric juxtaposition of mid-crustal amphibolite grade basement gneisses over low-grade upper crustal rocks emanating from the central axis of the transpressional belt.

    Whether afferent feedback contributes to the generation of cortico-muscular coherence (CMCoh) remains an open question. In the present study, a multivariate autoregressive (MVAR) model and partial directed coherence (PDC) were applied to investigate the causal influences between the central rhythm and electromyographic (EMG) signals in the process of CMCoh. The system modeling included activities from the contralateral and ipsilateral primary sensorimotor cortex (M1/S1), supplementary motor area (SMA) and the time series from extensor carpi radialis (ECR) muscles. The results showed that afferent sensory feedback could also play an important role for the generation of CMCoh. Meanwhile, significant coherence between the EMG signals and the activities in the SMA was found in two subjects out of five. Connectivity analysis revealed a significant descending information flow which possibly reflected direct recruitment on the motoneurons from the SMA to facilitate motor control. PMID:18756033

    The COmmon Muon and Proton Apparatus for Structure and Spectroscopy is a fixed target experiment at the CERN SPS accelerator. In the years 2008 and 2009 the collaboration focused on hadron spectroscopy: data with hadronic beams at a momentum of 190 GeV/c impinging on hydrogen, lead, nickel and tungsten targets were taken. In the preparation for this run-time, the apparatus was adapted to measure the formation of resonances by both diffractive scattering and central production. In the latter case, the study of charged pionic channels is well-suited to search for members of the f{sub 0} particle family, including some of the glueball candidates. The analysis of the newly taken data has started, these proceedings are meant to give a status and overview of the current activities.

    The areas of focus of the Santa Barbara and Riverside groups in conducting water demand studies are the central and southern California regional test sites, respectively. Within each test site, sub-areas have been selected for use in the making of detailed investigations. Within each of these sub-areas an in-depth evaluation is being made as to the capability of remote sensing systems to provide pertinent data relative to water demand phenomena. These more limited sub-areas are: (1) Kern County and the San Joaquin Basin; (2) Chino-Riverside Basin; and (3) the Imperial Valley. Rational for the selection of these subareas included the following: Much of the previous remote sensing research had been conducted in these areas and therefore a great deal of remote sensing imagery and pertinent ground truth for the areas was already available.

    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

    Context: Autism is a serious behavioral disorder among young children that now occurs at epidemic rates in developing countries like India. We have used tract-based spatial statistics (TBSS) of diffusion tensor imaging (DTI) measures to investigate the microstructure of primary neurocircuitry involved in autistic spectral disorders as compared to the typically developed children. Objective: To evaluate the various white matter tracts in Indian autistic children as compared to the controls using TBSS. Materials and Methods: Prospective, case-control, voxel-based, whole-brain DTI analysis using TBSS was performed. The study included 19 autistic children (mean age 8.7 years ± 3.84, 16 males and 3 females) and 34 controls (mean age 12.38 ± 3.76, all males). Fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD), and axial diffusivity (AD) values were used as outcome variables. Results: Compared to the control group, TBSS demonstrated multiple areas of markedly reduced FA involving multiple long white matter tracts, entire corpus callosum, bilateral posterior thalami, and bilateral optic tracts (OTs). Notably, there were no voxels where FA was significantly increased in the autism group. Increased RD was also noted in these regions, suggesting underlying myelination defect. The MD was elevated in many of the projections and association fibers and notably in the OTs. There were no significant changes in the AD in these regions, indicating no significant axonal injury. There was no significant correlation between the FA values and Childhood Autism Rating Scale. Conclusion: This is a first of a kind study evaluating DTI findings in autistic children in India. In our study, DTI has shown a significant fault with the underlying intricate brain wiring system in autism. OT abnormality is a novel finding and needs further research. PMID:26600581

    Wastewater constitutes an alternative water source for the irrigation sector. To fully benefit from it, and reduce possible adverse effects on public health and the environment, we need to look at the regulation of the practice. A prerequisite for this is an institutional analysis, and the points to consider are the institutional mandates. We used the city of Hyderabad, India, as a case study. There, irrigation with wastewater is not supported or recognized, but it happens in practice. It takes place in an indirect and unplanned way. Institutions fail at enforcing regulations, and little attention is given to formalization of the practice. With this article, we aim to untangle the institutional setup, and by doing so, identify the constraints surrounding development of a formal practice. Ultimately, we aim at contributing to the discussion on the agricultural use of wastewater. PMID:26177416

    2013-01-01

    Disaster recovery after the Indian Ocean tsunami in 2004 led to a number of challenges and raised issues concerning land rights and housing reconstruction in the affected countries. This paper discusses the resistance to relocation of fishing communities in Chennai, India. Qualitative research methods were used to describe complexities in the debate between the state and the community regarding relocation, and the paper draws attention to the dimensions of the state–community interface in the recovery process. The results of this study highlight the effects of differences in the values held by each of the stakeholders regarding relocation, the lack of community participation, and thereby the interfaces that emerge between the state and the community regarding relocation. The failure to establish a nexus between disaster recovery and the importance of a sustainable livelihood for fishing communities severely delayed housing reconstruction. PMID:23591625

    A qualitative study was conducted to obtain a detailed understanding of two key determinants of condom breakage - 'rough sex' and poor condom fit - identified in a recent telephone survey of female sex workers, in Bangalore, India. Transcripts from six focus-group discussions involving 35 female sex workers who reported condom breakage during the telephone survey were analysed. Rough sex in different forms, from over-exuberance to violence, was often described by sex workers as a result of clients' inebriation and use of sexual stimulants, which, they report, cause tumescence, excessive thrusting and sex that lasts longer than usual, thereby increasing the risk of condom breakage. Condom breakage in this setting is the result of a complex set of social situations involving client behaviours and power dynamics that has the potential to put the health and personal lives of sex workers at risk. These findings and their implications for programme development are discussed. PMID:24588078

    As maternal health specialists accelerate efforts towards Millennium Development Goal Five, attention is focusing on how to best improve service accountability to target communities as a strategy for more effective policy implementation. We present a case study of efforts to improve accountability in Orissa, India, focusing on the role of local women, intermediary groups, health providers and elected politicians. We highlight three drivers of success: (1) the generation of demand for rights and better services, (2) the leverage of intermediaries to legitimise the demands of poor and marginalised women and (3) the sensitisation of leaders and health providers to women's needs. We use the concepts of critical consciousness, social capital and 'receptive social spaces' to outline a social-psychological account of the pathways between accountability and service effectiveness.

    This paper presents the results of a case study of urban air quality over a densely populated city Ludhiana situated in Punjab, India, in the form of monthly and annual average concentrations of Suspended Particulate Matter (SPM), NO2 and SO2 for the periods 1988-1989, 1994-1999 and 2001-2005 which is generally found to be increasing with time and thus requires immediate corrective measures lest the situation becomes totally uncontrollable. The present situation is as bad as in other metropolitan Indian cities, although it seems to have somewhat improved as indicated by the latest 2001-2005 data in comparison with the past 1988-1989 and 1994-1999 data, but much more still needs to be done. In addition to the industrial and vehicular pollution, the agricultural pollution due to the burning of wheat and rice straws by the farmers should also be checked because it also creates tremendous pollution in the atmosphere.

    Background: Diabetic retinopathy (DR) is a leading cause of visual impairment in India. Available evidence shows that there are more than 60 million persons with diabetes in India and that the number will increase to more than a 100 million by 2030. There is a paucity of data on the perceptions and practices of persons with diabetes and the available infrastructure and uptake of services for DR in India. Objectives: Assess perception of care and challenges faced in availing eye care services among persons with diabetics and generate evidence on available human resources, infrastructure, and service utilization for DR in India. Methods: The cross-sectional, hospital-based survey was conducted in eleven cities across 9 States in India. In each city, public and private providers of eye-care were identified. Both multispecialty and standalone facilities were included. Specially designed semi-open ended questionnaires were administered to the clients. Semi-structured interviews were administered to the service providers (both diabetic care physicians and eye care teams) and observational checklists were used to record findings of the assessment of facilities conducted by a dedicated team of research staff. Results: A total of 859 units were included in this study. This included 86 eye care and 73 diabetic care facilities, 376 persons with diabetes interviewed in the eye clinics and 288 persons with diabetes interviewed in the diabetic care facilities. Conclusions: The findings will have significant implications for the organization of services for persons with diabetes in India. PMID:27144132

    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.

    Since 1998 there have been significant changes in the global distribution of bluetongue virus (BTV). Ten previously exotic BTV serotypes have been detected in Europe, causing severe disease outbreaks in naïve ruminant populations. Previously exotic BTV serotypes were also identified in the USA, Israel, Australia and India. BTV is transmitted by biting midges (Culicoides spp.) and changes in the distribution of vector species, climate change, increased international travel and trade are thought to have contributed to these events. Thirteen BTV serotypes have been isolated in India since first reports of the disease in the country during 1964. Efficient methods for preparation of viral dsRNA and cDNA synthesis, have facilitated full-genome sequencing of BTV strains from the region. These studies introduce a new approach for BTV characterization, based on full-genome sequencing and phylogenetic analyses, facilitating the identification of BTV serotype, topotype and reassortant strains. Phylogenetic analyses show that most of the equivalent genome-segments of Indian BTV strains are closely related, clustering within a major eastern BTV ‘topotype’. However, genome-segment 5 (Seg-5) encoding NS1, from multiple post 1982 Indian isolates, originated from a western BTV topotype. All ten genome-segments of BTV-2 isolates (IND2003/01, IND2003/02 and IND2003/03) are closely related (>99% identity) to a South African BTV-2 vaccine-strain (western topotype). Similarly BTV-10 isolates (IND2003/06; IND2005/04) show >99% identity in all genome segments, to the prototype BTV-10 (CA-8) strain from the USA. These data suggest repeated introductions of western BTV field and/or vaccine-strains into India, potentially linked to animal or vector-insect movements, or unauthorised use of ‘live’ South African or American BTV-vaccines in the country. The data presented will help improve nucleic acid based diagnostics for Indian serotypes/topotypes, as part of control strategies. PMID

  8. Role of deep convective in modulating tropospheric column ozone over Northern region of India: Case study of 2002

    The present study is an attempt to examine some of the probable causes for the unusually low tropospheric column ozone observed over the Eastern India during the exceptional drought event in July 2002. The analysis presented here aimed to characterize the possible link of the convective transport and tropospheric ozone distribution over the highly polluted northern plain of India. We examined horizontal wind and omega (vertical velocity) anomalies over the Indian region to understand the large scale dynamical processes prevailed during July 2002. It was found that, instead of normal large scale ascent over the Indian region, the air was descending in the middle and lower troposphere over vast part of India. This configuration was apparently responsible for less convective upwelling of precursors and likely caused less photochemical ozone formation in the free troposphere over the Eastern Indian during July 2002. The deep convection during Indian summer monsoon may thus have a significant role in regulating the chemical cycles associated with the change in tropospheric ozone over the Indian region. This study has shown that anomalous low TOR values in July 2002 over the eastern Indian region can be linked to the reduced transport of the precursors in the free troposphere than in normal years. To examine this effect the study of climatology of ozone over the period 2000-2009 has been done using vertical profiles data from ozonosonde dataset over three stations in India.

    This study was carried out to ascertain the allelic frequency of α(+)-thalassemia (α(+)-thal) in Scheduled caste and scheduled tribe populations of the Damoh district of Madhya Pradesh, India. Random blood samples of Scheduled tribe (267) and Scheduled caste (168), considering the family as a sampling unit, were analyzed for the presence of the -α(3.7) (rightward) (NG_000006.1: g.34164_37967del3804) and -α(4.2) (leftward) (AF221717) deletions. α(+)-Thal was significantly higher in the Scheduled tribals (77.9%) as compared to the scheduled caste population (9.0%). About 58.0% scheduled tribals carried at least one chromosome with the -α(3.7) deletion and 20.0% scheduled tribals carried the -α(4.2) deletion. Frequency for the -α(3.7) allele was 0.487 in the scheduled tribal populations in comparison to 0.021 in scheduled castes. Allelic frequency for -α(4.2) was 0.103 and 0.024, respectively, in the above communities. No Hardy-Weinberg equilibrium for α-thal gene (p < 0.05) was detected in the tribal population, indicating the presence of selection pressures in favor of α-thal mutation and adaptation.

    This study was carried out in three different cities of western Madhya Pradesh (India) to investigate the effects of long-term irrigation with industrial waste water (IWW), contaminated groundwater (CGW), and untreated municipal sewage water (USW) on soil fertility as well as on wheat crop yield. Irrigation with these three types of polluted water increased organic matter content as well as contents of available P (with IWW and USW only), available K, available S, available Zn, available Cu (IWW only), and available Mn (IWW and CGW only). The magnitude of improvement in soil fertility status was the highest in the case of USW, followed by IWW and finally, by CGW. Concentrations of Na in wheat leaf tissue increased by 198 and 58% whereas concentrations of Ca decreased significantly by 16 and 13% due to the use of IWW and CGW, respectively, resulting in poor Ca nutrition to the crop. Although wheat grain yield increased considerably due to USW, the same recorded significant decreases with IWW and CGW. In spite of the enhancement in the available nutrient status, decrease in wheat grain yield with the use of IWW and CGW could be due to the build-up of salts in the soil and an imbalance in the Na/Ca ratio in wheat crops irrigated with IWW and CGW. The adverse effect on wheat productivity was more pronounced with IWW as compared to CGW. PMID:24271649

    Introduction: Inadequate, inequitable distribution of the medical workforce remains a challenge across the globe, and India is no exception. Odisha, a state in India faces a major shortage of doctors particularly in rural and remote areas. In order to address this challenge, it is essential to understand medical students’ career plans, specialization preferences, choices of job location and sector, and views on working in rural and remote areas. This study explored the immediate and long-term career plans of final year medical students, their intended practice locations and underlying reasons for the choices. Methodology: A cross-sectional survey was conducted in all the medical colleges (three government and three private) in the state of Odisha. Through the systematic sampling method, data were gathered from 390 final year students. A semi-structured questionnaire was administered to the students and data were analyzed using SPSS version 20. Results: Of the 390 students, 290 (74.35%) were from a government college. The most preferred immediate career goal was postgraduation studies (45.9% of students in government medical schools and 54% in private). About 17% of government students and 9% of private students showed willingness to work in rural areas, in the long run. Nearly 44.5% mentioned opportunities for career growth, followed by the possibilities for higher education (26.8%) as major the factors for preferring an urban posting. Similarly, higher pay scales, better working conditions were major factors for preferring the private sector. Most of the students maintained that good housing, better salaries, and adequate facilities at the workplace would attract more students toward rural service. Conclusion: Since public funded medical students are not motivated to serve in rural settings, increasing the number of places or establishing new medical institutions may not be an effective solution to the issue.

    Objective To assess the effect of experienced stigma on depth of multidimensional poverty of persons with severe mental illness (PSMI) in Delhi, India, controlling for gender, age and caste. Design Matching case (hospital)–control (population) study. Setting University Hospital (cases) and National Capital Region (controls), India. Participants A case–control study was conducted from November 2011 to June 2012. 647 cases diagnosed with schizophrenia or affective disorders were recruited and 647 individuals of same age, sex and location of residence were matched as controls at a ratio of 1:2:1. Individuals who refused consent or provided incomplete interview were excluded. Main outcome measures Higher risk of poverty due to stigma among PSMI. Results 38.5% of PSMI compared with 22.2% of controls were found poor on six dimensions or more. The difference in multidimensional poverty index was 69% between groups with employment and income of the main contributors. Multidimensional poverty was strongly associated with stigma (OR 2.60, 95% CI 1.27 to 5.31), scheduled castes/scheduled tribes/other backward castes (2.39, 1.39 to 4.08), mental illness (2.07, 1.25 to 3.41) and female gender (1.87, 1.36 to 2.58). A significant interaction between stigma, mental illness and gender or caste indicates female PSMI or PSMI from ‘lower castes’ were more likely to be poor due to stigma than male controls (p<0.001) or controls from other castes (p<0.001). Conclusions Public stigma and multidimensional poverty linked to SMI are pervasive and intertwined. In particular for low caste and women, it is a strong predictor of poverty. Exclusion from employment linked to negative attitudes and lack of income are the highest contributors to multidimensional poverty, increasing the burden for the family. Mental health professionals need to be aware of and address these issues. PMID:25712818

    ABSTRACT 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

  14. Case studies of innovative medical device companies from India: barriers and enablers to development

    PubMed Central

    2013-01-01

    Background Over 75% of the medical devices used in India are imported. Often, they are costly and maladapted to low-resource settings. We have prepared case studies of six firms in Bangalore that could contribute to solving this problem. They have developed (or are developing) innovative health care products and therefore are pioneers in the Indian health care sector, better known for its reverse engineering skills. We have sought to understand what enablers and barriers they encountered. Methods Information for the case studies was collected through semi-structured interviews. Initially, over 40 stakeholders of the diagnostics sector in India were interviewed to understand the sector. However the focus here is on the six featured companies. Further information was obtained from company material and other published resources. Results In all cases, product innovation has been enabled by close interaction with local medical practitioners, links to global science and technology and global regulatory requirements. The major challenges were the lack of guidance on product specifications from the national regulatory agency, paucity of institutionalized health care payers and lack of transparency and formalized Health Technology Assessment in coverage decision-making. The absence of national evidence-based guidelines and of compulsory continuous education for medical practitioners were key obstacles in accessing the poorly regulated and fragmented private market. Conclusions Innovative Indian companies would benefit from a strengthened capacity and interdisciplinary work culture of the national device regulatory body, institutionalized health care payers and medical councils and associations. Continuous medical education and national medical guidelines for medical practitioners would facilitate market access for innovative products. PMID:23721110

    Background Various Serosurveys and studies provide ample evidence of differing perspectives regarding epidemiology of HAV and HEV in India. This study was conducted to assess the seroprevalence of HAV and HEV and its associated factors with an aim to provide inputs to planners regarding requirement of HAV vaccine. Methods A multi-centric cross sectional survey amongst 4175 healthy trainees (young adults) was carried out in training centres, selected by multistage random sampling, giving equal representation to all regions of India. Sample size was calculated by taking prevalence of HAV seropositivity amongst adults as 60% and alpha 0.05. Results Seroprevalence for HAV and HEV was 92.68% (95% CI 91.82, 93.47) and 17.05% (15.90, 18.26), respectively. Logistic regression showed that hand washing without soap, regular close contact with domestic animals, consumption of unpasteurized milk and regular consumption of food outside home were risk factors for HAV (p < 0.05). For HEV, irregular hand washing, consumption of unpasteurized milk and irregular consumption of freshly prepared food were risk factors (p < 0.05). Conclusion High level of immunity against HAV among the healthy young adults clearly demonstrates that vaccination against HAV is not required at present in our country. The large proportion being susceptible to HEV points towards the requirement of preventive strategies in the form of safe drinking water supply, hygiene, sanitation, increasing awareness and behaviour change with respect to personal hygiene especially hand and food hygiene.

    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

    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

    Mexico City Metropolitan Area has been the object of several well know intensive campaigns. Since MARI (1991) , IMADA (1997), MCMA 2003 and MILAGRO (2006). The spatial scope of these studies have gone from urban to regional to continental, with the focus on MCMA as an emissions source. During MILAGRO, the influence on MCMA of wildfires and agricultural biomass burning around the megacity was considered. However, around Mexico City a crown of metropolis and middle size cities make a region known as the Central Mexico Regional Crow (CRCM for its acronym in Spanish language) or Central Mexico City Belt. It contains 32 million inhabitants and produces 40% of national gross product. The region undergoes an uncontrolled urban sprawl. Evidence is building-up on complex air pollution transport processes between the air basins within CRCM. However, only MCMA counts with reliable long-term records of criteria pollutants monitoring. Only few intensive campaigns have been done in the air basins surrounding MCMA. ECAIM project has several goals: a) To use ground and satellite observations to assess emissions inventories; b) To use ground and satellite observations to assess the performance of air quality models for the whole region; c) to produce critical levels exceedence maps; d) To produce a preliminary diagnostic of air quality for the CRCM; e) to produce a preliminary estimate of the cost of air pollution within the CRCM. In this work we show the method approach to use the best available information from local AQM networks, field campaigns, satellite observations and modeling to achieve those goals. We show some preliminary results.

  19. A numerical study of the upwelling circulation off Central Chile

    NASA Astrophysics Data System (ADS)

    Mesias, Jorge M.

    The summer upwelling circulation off Central Chile between 34°--40°S is studied using the Princeton Ocean Circulation numerical model, implemented with realistic atmospheric forcings and bottom topography. The simulations are made for summers of years 1992, 1993, and 1994. Sea surface temperature (SST) from the model results and satellite sensors (derived from NASA/NOAA Pathfinder Project datasets) are compared to determine regions where the numerical simulations more realistically represent the oceanic fields. The summer local winds are predominantly equatorward and fluctuate affected by the seasonal displacement of the Subtropical Anticyclone of the Southeast Pacific. The model ocean circulation shows the presence of a surface coastal equatorward jet flowing over a poleward undercurrent that spreads over the continental shelf and slope break. These currents resemble those historically observed off Central Chile, following a classical Ekman-geostrophy dynamics. The oceanic variability is strongly related to the variability of the local wind forcing, bottom relief, and coastline geometry. Strong wind fluctuations induce the formation of cyclonic/anticyclonic mesoscale eddies, favored by the separation of the equatorward jet from the coast, downstream of a prominent mid-domain cape. The flow variability between regions depends on the spatial variability of the wind forcing. The wind relaxation is larger in the southern regions, where the upwelling tends to disappear. In the northern areas, the separation of the jet and the formation of eddies induce a strong cross-shelf transport activity. Comparisons among SST fields for all years indicate that the model and satellite fields vary in similar patterns, especially in the northern coastal areas, and suggest that oceanic fields are largely affected by changes in local winds during El Nino events. During El Nino periods, the upwelling activity weakens due to a rapid decrease of the equatorward winds, and the passage of

    Introduction Testicular and para-testicular neoplasm are rare type of tumours affecting adolescents and young adults, reflected by the paucity of published data in India. Aim This study was undertaken to estimate the epidemiological characteristics and histological types and subtypes of testicular neoplasm according to the WHO classification in our patient group. Identification of histopathological pattern of testicular tumour is immensely important for improved management protocols. Materials and Methods This was a retrospective study done over a period of ten years from 2004 to 2014 in a tertiary care centre. All relevant clinical data including patient’s age, laterality, history of risk factors and serum tumour markers were collected from records. Histopathological slides were retrieved and reviewed for tumour and its subtype and classified according to WHO classification (2004). Results A total of 37 cases of testicular and paratesticular neoplasm were encountered in our study with a mean age of 38.1 years. Right testis was affected in 70.3% of cases. The most common clinical presentation was scrotal swelling with heaviness. Germ cell tumour was the most common type accounting for 77.1% followed by lymphomas (17.1%). Germ cell tumours were categorized into seminomatous (48.2%) and non-seminomatous tumours (51.8%). The most common subtype of non-seminomatous tumours was mixed germ cell tumour accounting for 85.8%. Conclusion The incidence of testicular neoplasm among general population in Asian countries is low, as reflected in the very few studies that have been performed and published in literature. Epidemiological and histomorphological spectrum of our study was comparable to most of the countries except for some African and Western countries.

  1. Technology policy and sustainability: An empirical study of renewable energy development in India

    NASA Astrophysics Data System (ADS)

    Iyer, Maithili

    In the debate over sustainability and development paradigms, energy assumes a unique position by virtue of its direct link with environmental sustainability and its role as an essential vehicle for development. Agenda 21 recognizes that coupling end-use energy efficiency with renewable sources of energy will help meet a large share of the world's energy needs while reducing the environmental impacts of energy use. Nevertheless, the extent and scope of diffusion of new and renewable energy technologies is contingent upon the capabilities of the countries concerned to realize firstly, a need, and subsequently, the resources for utilizing the technologies. India has one of the largest renewable energy programs (REPs) in the world, however, renewables continue to remain a marginal contributor to the total energy supply. The need to fundamentally change the program design of REPs has been suggested by many critics and experts in view of the implementation problems. However, mainstream thinking maintains that Poor financial conditions in the energy sector, not program design flaws, are at the heart of poor implementation results, leading to the premise that infusion of capital and efforts at market transformation through the involvement of the private sector could solve the problem. This dissertation uses case studies on solar photovoltaics, wind energy, and biogas in India to analyze the implementation of renewable energy technologies. Based on stakeholder interviews, documents, and site visits, this dissertation argues that the problems currently recognized are in reality symptomatic of a combination of three underlying problems: (1) An inadequate understanding of the needs of energy users and the complex interplay of existing policies and technological choices with user needs and behavior; (2) An institutional network, both at the local and the national level, that lacks the capacity to facilitate information exchange within and between institutions, thereby losing

    The stable isotopic compositions of all major daily rain fall samples (n = 113) collected from Kozhikode station in Kerala, India, for the year 2010 representing the pre-monsoon, southwest and northeast monsoon seasons are examined. The isotopic variations δ(18)O, δ(2)H and d-excess in daily rainfall ranged from δ(18)O: -4.4 to 2 ‰, δ(2)H: -25.3 to 13.8 ‰, and d-excess: -2.4 to 15.3 ‰; δ(18)O: -9.7 to -0.6 ‰, δ(2)H: -61.7 to 5.3 ‰, and d-excess 5.8 to 17.4 ‰; δ(18)O -11.3 to -1.4 ‰, δ(2)H: -75.3 to 0.9 ‰, and d-excess: 8.8 to 21.3 ‰ during the pre-, southwest and northeast monsoon periods, respectively. Thus, daily rainfall events during two monsoon periods had a distinct range of isotopic variations. The daily rain events within the two monsoon seasons also exhibited periodic variations. The isotopic composition of rain events during pre-monsoon and a few low-intensity events during the southwest monsoon period had imprints of secondary evaporation. This study analysing the stable isotopic characteristics of individual rain events in southern India, which is influenced by dual monsoon rainfall, will aid in a better understanding of its mechanism.

    India has high incidence of Gallbladder carcinoma with regional variation in incidence possibly due to environmental factors. Prospective study of all the gall bladder cancer in our hospital over 18 months analysing how the epidemiological factors are influencing the disease. Incidence-Four cases per 100,000 populations per year. The peak incidence was in 41 to 50 years group (49.20 %). Male to female ratio was 1:3.8. Majority (69.84 %) were in lower socio-economic group. 61 out of 63 patients (96.62 %) were non-vegetarians. 60.34 % and 19.04 % patients weighed between 50 and 55 kg and 55and 60 kg respectively (p = 0.003). Male smokers had significantly higher risk (p = 0.000 1). Gall stones were present in 45 out of 63 cases(71.42 %).45 out of 63 patients were typhoid carriers (p < 0.05). Pain abdomen was the commonest complaint (87.30 %), followed by pallor, lump in right upper quadrant, nausea & vomiting and jaundice in 71.42 %, 69.84 %, 66.66 %, 31.74 % patients respectively. This data highlights high prevalence of gall bladder carcinoma in Eastern India. Better hygiene and water supply to prevent typhoid carriers, prevention of malnutrition, early intervention for cholelithiasis, importance of balanced diet, increase in awareness about risk of tobacco and alcohol consumption-all are highlighted as significant modifiable factors.

    Various attempts have been made in India with respect to decentralization, most significantly the 73rd Amendment to the Constitution of India (1993) which provided the necessary legal framework for decentralization to take place. However, the outcome has been mixed: an evaluation of the impact of decentralization in the health sector found virtually no change in health system performance and access to health services in terms of availability of health personnel or improvement in various health indicators, such as Infant Mortality Rates or Maternal Mortality Ratio. Subsequently, there has been a conscious effort under the National Rural Health Mission (NRHM)-launched in 2005-to promote decentralization of funds, functions and functionaries to lower levels of government; and Karnataka had a head-start since devolution of all 29 functions prescribed by the 73rd Amendment had already taken place in the state by the late 1990s. This study presents the findings of an on-going research effort to build empirical evidence on decentralization in the health sector and its impact on system performance. The focus here is on analyzing the responses of health personnel at the district level and below on their perceived 'Decision Space'-the range of choice or autonomy they see themselves as having along a series of functional dimensions. Overall, the data indicate that there is a substantial gap between the spirit of the NRHM guidelines on decentralization and the actual implementation on the ground. There is a need for substantial capacity building at all levels of the health system to genuinely empower functionaries, particularly at the district level, in order to translate the benefits of decentralization into reality.

    The Kolong River of Nagaon district, Assam has been facing serious degradation leading to its current moribund condition due to a drastic human intervention in the form of an embankment put across it near its take-off point from the Brahmaputra River in the year 1964. The blockage of the river flow was adopted as a flood control measure to protect its riparian areas, especially the Nagaon town, from flood hazard. The river, once a blooming distributary of the mighty Brahmaputra, had high navigability and rich riparian biodiversity with a well established agriculturally productive watershed. However, the present status of Kolong River is highly wretched as a consequence of the post-dam effects thus leaving it as stagnant pools of polluted water with negligible socio-economic and ecological value. The Central Pollution Control Board, in one of its report has placed the Kolong River among 275 most polluted rivers of India. Thus, this study is conducted to analyze the seasonal water quality status of the Kolong River in terms of water quality index (WQI). The WQI scores shows very poor to unsuitable quality of water samples in almost all the seven sampling sites along the Kolong River. The water quality is found to be most deteriorated during monsoon season with an average WQI value of 122.47 as compared to pre-monsoon and post-monsoon season having average WQI value of 85.73 and 80.75, respectively. Out of the seven sampling sites, Hatimura site (S1) and Nagaon Town site (S4) are observed to be the most polluted sites.

    Background: Sickle cell disease is a major genetic and public health challenge in India. Adequate studies on clinico-hematological aspects of disorders are available, however there are few studies on the public health and reproductive outcomes among sickle cell carrier couples. Methods: A total of 383 couples including their offspring with at least one case of sickle cell disorder referred to a testing center from a tertiary hospital from March 2010 to February 2013 were consecutively studied as matched case controls. Results: Out of 383 couples, 200 were found normal and 183 had different sickle cell disorders. Carrier couples of sickle cell disease had significantly higher fertility (mean number of conceptions, i.e. 3.153 versus 1.480) and higher below 10 year mortality (11% versus 2.7%) and lower surviving offspring (877.4 versus 970.6) than of controls. Neonatal and infant mortality was doubled (34.3 versus 14.7) and three-fold higher (44.1 versus 14.7), respectively in carriers of disease per 1000 live-births compared to controls. Couples of AS/SS genotype showed high neonatal, infant, below 10 year mortality (214.3 each) and low surviving offspring (785.7 per 1000 live-births). Conclusions and Global Health Implications: Sickle cell carrier couples are increasing in both trait and disease offspring (surviving: 56.7% against 43.3% normals). This increased production of carrier and disease offspring leads to increased morbidity, neonatal/infant and childhood mortality, and adversely affects the survival fitness.

  7. Financial study of commercialization of solar central receiver power systems

    NASA Astrophysics Data System (ADS)

    1981-03-01

    Commercialization requires that central receiver (CR) systems meet the economic criteria used by industry to select systems for capital ventures. Quantitative estimates are given of the investment required by government, utilities, and the manufacturing sector to meet the energy displacement goals for central receiver technology. Initial solar repowering and stand-alone electric utility plants will not have economic comparability with competitive energy sources. A major factor for this is that initial (first of a kind) heliostat costs will be high. As heliostat costs are reduced due to automated manufacturing economies, learning, and high volume production, central receiver technology will become more competitive. Under this task, several scenarios (0.1, 0.5, and 1.0 quad/y) were evaluated to determine the effect on commercial attractiveness and to determine the cost to government to bring about commercialization of solar central receivers.

    Background: Pemphigus is a group of chronic autoimmune vesico-bullous disorders in which the epidermis and the basement membrane zone are the focus of attack resulting in cutaneous and mucosal blister formation. Direct immunofluorescence (DIF) test is a very sensitive test for the diagnosis Aim: To study the clinico histopathological patterns of pemphigus in eastern India. The study also aims to correlate DIF with clinical and histologic findings as well as severity of skin involvement [scoring systems]. Materials and Methods: Total 41 patients were studied over a period of 1 year in the Post-graduate centre of Dermatology in Eastern India. DIF, histopathology and clinical data were correlated. Results: In our study Pemphigus vulgaris (PV) was the predominant type with 32 cases followed by 8 cases of pemphigus foliaceus (PF) and a single case of IgA pemphigus. Mean age at presentation was late middle age. Majority of the patients, 26 (63.41%) initially had cutaneous involvement followed by mucosal involvement. In this study group 36 (87.80%) patients showed acantholytic cells on histopathological examination. Most patients of PV showed suprabasal blister 20 (62.50%) followed by intraspinous 5 (15.62%) and subcorneal 5 (15.62%) blister. In majority 28 (87.50%) of the PV patients IgG and C3 antibodies were deposited throughout the epidermis. The strength of antibody positivity was strong in most of the patients (71.87%). In cases of PF mostly IgG 6 (75%) antibodies were deposited in the upper epidermis. DIF intensity had poor correlation with disease activity/severity except in PF. Conclusion: Almost 85.36% cases of pemphigus were diagnosed clinicopathologically. But 6 cases couldn’t be diagnosed accurately on clinicopathological basis and in them DIF was confirmatory. Two cases of pure mucosal PV and 1 case of IgA pemphigus was confirmed by DIF. Two cases of bullous pemphigoid clinico-histologically mimicking PV were also excluded by DIF. So it appears from our

    Background Sericulture plays an eminent role in development of rural economy in India. Silk filature is a unit where silk is unwound from the cocoons and the strands are collected into skeins. During the process workers are exposed to the high molecular weight proteins like Sericin and Fibroin which are potent allergens leading to sensitization over a period of time and subsequently occupational related health disorders. Objective To identify and compare the magnitude of silk allergen sensitization in workers of silk filatures. Methods A community based comparative descriptive study was conducted for a period of 1 year at Ramanagara in south India. One hundred twenty subjects working in the silk filatures formed the study group. For comparison, 2 types of controls were selected viz.120 subjects who were not working in the silk filatures but resided in the same geographical area (control A) and 360 subjects who were not working in silk filatures as well not residing in the same geographical area (control B). Skin prick test was used to identify the silk allergen sensitization. Results Mean age was 34.14 ± 2.84 years in the study group. Mean age was 40.59 ± 14.40 years and 38.54 ± 12.20 years in control A and control B, respectively. There were 35 males (29.16%) and 85 females (70.84%) in the study group. There were 58 (48.34%) males and 62 (51.66%) females and 152 (42.2%) males and 208 females (57.8%) in control A and control B, respectively. Sensitization to silk allergen was 35.83% in the study group and 20.83% in the control group A and 11.11% in control group B. There was difference in the allergen sensitivity between the study group and control groups and it was statistically significant (chi-square = 38.08; p < 0.001). Conclusion There is high burden of silk allergen sensitization among silk filature workers. PMID:27141481

    An investigation was made into coccidiosis of 190 scavenging indigenous chickens between September 2000 and April 2001 in three selected agroclimatic zones, in central Ethiopia. This was done through clinical, postmortem and microscopic examinations. Data were processed by chi-square and Mantel-Haenzel test. The study indicated that 25.8% (49/190) of the chickens were infected with coccidiosis and found to harbour one to four different species of Eimeria. Of these infected chickens, 30 (15.8%) and 19 (10.0%) were positive for clinical and sub-clinical coccidiosis, respectively. There was a significant altitude difference (chi2 = 14.7, p <0.001) in coccidiosis prevalence: 42.2% in chickens from highland region followed by 21.5% in mid-altitude and 13.1% in low-altitude areas. When quantified, the prevalence of coccidiosis was 2.66 and 4.83 times higher in the high-altitude than in mid-altitude (odds ratio, OR = 2.66, p<0.05) and low-altitude (OR = 4.83, p<0.001) chickens. The pathogenic Eimeria species responsible for clinical coccidiosis were E. necatrix, E. acervulina, E. maxima and E. tenella. With increasing demand for poultry products in developing countries, knowledge of production constraints in traditional management practices could help devise control strategies for constraints on backyard poultry production systems.

    Former comparison of climate sensitive proxies from natural archives of the northern monsoon domain with proxy data from mid and high latitude archives have proven a correlation between the proxies of both regions. But still some ambiguities concerning the mechanisms that drive this correlation exist. During our investigation of a sediment core from Lonar Lake in central India, which covers the complete Holocene sedimentation history of the lake, we could identify several phases of centennial scale climate alteration on the basis of stable carbon and nitrogen isotope ratios, mineralogy, and amino acid derived degradation proxies. These phases correlate with climate sensitive proxies from the North Atlantic region as well as with 14C nuclide production rate, which indicates changes in solar output. The results from this first continuous, high resolution record of Holocene climate history from central India indicate sensitivity of monsoon climate to solar forcing. Additionally, a connection between North Atlantic climate and the climate of a region that is not affected by the Westerlies or shifts of the summer ITCZ to a position south of the investigation site could be identified.

    2014-12-01

    Scientists at the University of South Florida (USF) have been working in Central America for several decades. Efforts have focused on Physical Volcanology in Nicaragua, GPS in Costa Rica, and assessment of Geothermal projects in El Salvador, amongst others. Two years ago a Seismology Lab was established at USF. Personnel now include three Professors, a Post-Doc, and 4 graduate students. Seismic and GPS networks were installed at Telica Volcano, Nicaragua, in 2010 by Roman, LaFemina and colleagues. Data are recorded on site and recovered several times per year at this persistently restless volcano, which has rates of 5 to 1400 low frequency seismic events per day (Rodgers et al., submitted). Proposals have been submitted to install instruments on other Nicaraguan volcanoes, including seismometers, GPS, infrasound, and lightning sensors. This suite of instruments has proven to be very effective to study a range of volcanic processes. The proposals have not been successful to date (some are pending), and alternative funding sources are being explored. One interesting scientific issue is the presence of strong seasonal effects, specifically a pronounced rainy season and dry season and possible interaction between shallow volcanic processes and surface waters. We are also pursuing a variety of studies that are complementary to the instrumental efforts. One such study is examining volcanic earthquake swarms, with the focus to date on identifying diagnostics. One clear pattern is that peak rates often occur early in swarms, whereas the largest M event occurs late. Additional evidence suggests that the seismic source size grows systematically, especially for events with similar waveforms (families). Recognition of such patterns, linked to processes, may help to improve monitoring and better take advantage of instrumental data to reduce vulnerability from eruptions.

    India being a country with vast diversity is expected to have different dietary and life style patterns which in turn may lead to population-specific environmental risk factors. Further, the interaction of these risk factors with the genetic makeup of population makes it either susceptible or resistant to cardiovascular disease. One such candidate gene is angiotensin converting enzyme (ACE) for various cardiovascular mechanisms. ACE is the key enzyme of the renin angiotensin aldosterone system pathway which maintains homeostasis blood pressure in the body and any variation in the levels is reported to be associated with various complex diseases. The DD genotype is found to increase ACE levels, which is associated with cardiovascular diseases and decrease in ACE levels are associated with kidney diseases. The aim of this study was to understand the distribution of ACE I/D polymorphism and ACE levels among Brahmins of National Capital Region (NCR) north India, with respect to age and sex ratio distribution. In this study, 136 subjects of which 50 males and 86 females, who were unrelated up to first cousin, aged 25 to70 years were studied. ACE gene was found to be polymorphic with high frequency of heterozygote (ID) followed by II and DD genotypes. The studied population was found to be in Hardy-Weinberg equilibrium with respect to ACE I/D polymorphism (P = 0.55). I allele frequency was found to be higher (0.560) than the D allele (0.44). The median level of ACE was found to be 65.96 ng/mL (48.12-86.24) which is towards lower side of the normal range. ACE levels were found to be increased among individual having either of the homozygotes that is II or DD and higher frequency of heterozygote (ID) is indicative of advantage in the population by maintaining lower ACE levels. The limitation of the present study is low sample size, however, the merit is that the subjects belonged to a Mendalian population with a common gene pool. PMID:27350671

    Landslides - mass movements of rock, debris or earth down a slope - are worldwide phenomena which cause significant damage and an estimated 5000 fatalities each year. They are caused by the interplay of various natural and anthropogenic factors and occur under diverse geoenvironmental conditions. In India, landslides occur primarily in the Himalayas of North India and in the Western Ghats of South India. This paper reports the results of field investigations for six landslide sites in North, Northeast and South India. We provide explanations as to why several landslides occurred at each of the sites. Our goal is to gain a deeper insight into the causes and precursors of landslides, which will facilitate more accurate identification of landslide-prone locations and enable early detection of landslide events.

    Five types of long-lasting insecticidal nets (LNs), namely, Olyset, Netprotect, PermaNet, DuraNet, and Interceptor, were tested after 20 washes for efficacy in terms of mortality, deterrence effect, blood-feeding inhibition, and induced exophily of the malaria vector Anopheles fluviatilis in experimental huts in Malkangiri district of Odisha State, India. Efficacy of the three synthetic pyrethroids (SPs) used in the LNs was also analyzed. Use of LNs reduced the entry of An. fluviatilis into the huts by 73.3-83.2%, and the five LNs were comparable in terms of deterrence. The exit rate of An. fluviatilis from the huts with untreated net was 56.3%, and relative to this, Olyset followed by DuraNet induced significantly a higher exophily. In contrast, the exit rate was significantly lower with Interceptor. Among the three SPs, permethrin induced significantly greater exophily relative to the untreated control, and as a result of this, permethrin-treated Olyset produced a lower mortality. Blood-feeding rate of An. fluviatilis was significantly lower with all the five LNs than the control. Similarly, all the three SPs significantly inhibited blood feeding compared with the control. Interceptor and DuraNet, both alphacypermethrin-treated LNs, caused relatively a higher mortality of An. fluviatilis than the other LNs. The five brands of LNs and three SPs tested in the current study were equally effective in terms of deterrence and blood-feeding inhibition; only exiting and killing effect differed among them. Permethrin-treated LNs induced greater exophily, while, overall, alphacypermethrin-treated LNs killed more An. fluviatilis that entered the huts. Advantage of deterrence, excito-repellent, and killing effects of LNs and appropriate selection of SP for net treatment are discussed in this paper. PMID:25118410

    In order to enhance food production, India has adopted modern agriculture practices and achieved noteworthy success. This achievement was essentially the result of a paradigm shift in agriculture that included high inputs of agrochemicals, water, and widespread practice of monoculture, as well as bureaucratic changes that promoted these changes. There are very few comprehensive analyses of potential adverse health outcomes that may be related to these changes. The objective of this study is to identify health risks associated with modern agricultural practices in the southern Indian state of Karnataka. This study aims to compare high-input and low-input agricultural practices and the consequences for health of people in these communities. The fieldwork was conducted from May to August, 2009 and included a survey carried out in six villages. Data were collected by in-depth personal interviews among 240 households and key informants, field observations, laboratory analyses, and data from secondary sources. The study identified four major visible impacts: occupational hazards, vector borne diseases, changing nutritional status, and inequity in development. In the high-input area, mechanization has resulted in more occurrences of serious accidents and injuries. Ecological changes due to rice cultivation in this area have further augmented mosquito breeding, and there has been a surge in the incidence of Japanese encephalitis and malaria. The traditional coarse cereals (complex carbohydrates, high protein) have been replaced by mill-polished rice (simple carbohydrate, low protein). The prevalence of overweight (BMI>25) has emerged as a new public health challenge, and this is most evident in large-landholding households, especially in the high-input agriculture areas. In all agro-ecological areas, it was observed that women faced a greater risk of both extremes of under-nutrition and being overweight. Output-driven and market-oriented modern agricultural practices have

    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

    This paper examines cognition measures by age and gender from two types of studies in China and India. It finds that despite some notable differences in samples and measures, a general strong association of cognition in older ages with education emerges as a potential explanation for gender gaps and cohort differences. Female disadvantage in cognition is greater in India, both before and after controlling for education. The process of rural-urban migration draws more cognitively able women to cities in China but not in India. The advent of modern longitudinal studies of aging in these developing countries holds great promise for future work. PMID:25506546

    An attempt is made to study the planetary boundary layer (PBL) characteristics during the winter period at Anand (22.4°N, 72.6°E), a semi-arid region, which is located in the western part of India. A one-dimensional turbulent kinetic energy (TKE) closure model is used for the study. The structure of the PBL,which consists of profiles of zonal and meridional components of wind,potential temperature and specific humidity, is simulated. A one-dimensional soil heat and moisture transport parameterization scheme is incorporated for the accurate representation of the energy exchange processes at the soil-atmosphere interface. The diurnal variation of fluxes of sensible heat, latent heat, shortwave radiation, net radiation and soil flux, soil temperature at different depths, Richardson number and TKE at the height of the constant flux layer is studied. The model predictions are compared with the available observations obtained from a special Land Surface Processes (LSP) experiment.

    An attempt is made to understand uranium series disequilibrium in unconformity proximal related uranium mineralisation in Chenchu colony area, Guntur district, Andhra Pradesh, India. The uranium mineralization in Chenchu colony is the western continuity of the Koppunuru uranium deposit and predominantly hosted by gritty quartzite/conglomerate, which occasionally transgresses to underlying basement granite/basic rock. Disequilibrium studies are based on borehole core samples (35 boreholes, No. of samples=634) broadly divided in two groups of cover rocks of Banganapalle formation (above unconformity) and basement granites (below unconformity). Linear regression coefficient between uranium and radium is 0.95, which reflects excellent correlation and significant enrichment of parent uranium. Disequilibrium studies have indicated predominant disequilibrium in favour of parent uranium (35%), which is probably due to the weathering process causing migration of some of the radionuclides while dissolution of minerals due to groundwater action might have also played a significant role. Further, escape of radon might have accentuated the disequilibrium factor resulting in an increase in the grade of the mineralization. This is well corroborated by the presence of fractures and faults in the study area providing channels for radon migration/escape. PMID:26313623

    India's Unnao region is home to many leather-treatment facilities and related industries. Industrial and agricultural waste leads to heavy metal contamination that infiltrates groundwater and leads to human health hazards. This work measured the amount of heavy metal in groundwater at specific sites near the industrial facilities in Unnao and identified potential sources of contamination as anthropogenic or lithogenic. Groundwater samples were taken from 10 bore well sites chosen for depth and proximity to industry. Data obtained from sample sites was interpreted using a multivariate statistical analytical approach, i.e., principal component analysis, clustering analysis, and correlation analysis. The results of the multivariate analysis showed that cadmium, copper, manganese, nickel, lead, and zinc were correlated with anthropogenic sources, while iron and chromium were associated with lithogenic sources. These findings provide information on the possible sources of heavy metal contamination and could be a model for assessing and monitoring heavy metal pollution in groundwater in other locales. This study analyzed a selection of heavy metals chosen on the basis of industries located in the study area, which might not provide a complete range of information about the sources and availability of all heavy metals. Therefore, an extended investigation on heavy metal fractions will be developed in further studies. PMID:24488365

    Objective: To assess the birth prevalence and pattern of congenital heart disease (CHD) using echocardiography in babies born in a community hospital of North India. Methods: A cross-sectional observational study conducted over a period of 3 years. Newborns born over a specific 8-h period of the day were recruited in the study. They underwent routine clinical examination and pulse oximetry, followed by screening echocardiography for diagnosing a CHD. Results: A total of 20,307 newborns were screened, among which 874 had abnormal echocardiograms; 687 had insignificant CHDs, 164 had significant CHDs, and 24 had other abnormal cardiac findings. The birth prevalence of significant CHDs was 8.07 per 1000 live births; 131 newborns had an acyanotic CHD (79.9%) and 33 a cyanotic CHD (20.1%). Ventricular septal defect (VSD) was the most common acyanotic CHD, present in 116 newborns, giving a prevalence of 5.7/1000 live births. Among the cyanotic CHD, transposition of great arteries was most common (prevalence 0.34/1000 live births). Conclusion: The CHD birth prevalence in our study is similar to the reported worldwide birth prevalence. Acyanotic CHD (mostly VSD) is seen in about three-fourths of babies born with CHD. The more sinister cyanotic CHD is present in remaining 25%. PMID:27625516

    The Pan-African Hook batholith is emplaced N of the Mwembeshi dislocation, a regional scale structure at the contact between Zambezi Belt and Lufilian Arc in Central Zambia. Exposed over 12000 km2 the batholith is composed mainly of fine-grained and coarse-grained porphyritic granites and leucogranites affected by solid-state deformation along high-strain zones. Two main zones of deformation were investigated - the Itezhi-Tezhi Zone (ITZ) in the SW part of the batholith and the Nalusanga Zone (NZ) to the NE. The 2.5 km wide, N-S trending, subvertical ITZ is a medium-grade, pure shear dominated structure, reflecting probably regional scale E-W shortening. In the central part of the zone, augen-gneiss textures developed. Mineral lineations plunging ~40° S are recorded occasionally. The deformed feldspar porphyroclasts show symmetrical tails and rarely sinistral stair-stepping. In the SE part of the Hook batholith the continuation of the ITZ trends E-W. This orientation can be explained by rotation of the original ITZ trend by N-S shortening that also has been recorded in the siliciclastic metasediments S of the contact. S dipping, up to 15 cm wide thrust zones observed in the ITZ area were probably formed during this tectonic event. The 3 km wide NZ is a subvertical to steeply SSW dipping structure, parallel to the NE contact of the batholith, with well-developed foliation and mineral stretching lineations. Field and microstructural analyses defined the NZ as a medium-grade, non-coaxial, sinistral strike-slip shear zone. The transition from weak foliated granite to S-C mylonites and ultramylonites was observed. The sinistral shearing is consistent with E-W shortening in agreement with the tectonic framework of the ITZ. The low grade metasediments to the E of the granite are folded in N to NNW trending structures also implying E-W shortening. Temperature conditions during the deformation in ITZ and NZ inferred from microstructural analyses are about 500°-550°C. The

    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

    Objectives: The aim was to assess and compare the prevalence of orthodontic treatment need among various special health care needs (SHCN) schoolchildren and adolescents in Dharwad, India. Materials and Methods: This cross-sectional study was carried out among 492 subjects in age group of 12-19 years (mean age 14.02 ± 1.84 standard deviation [SD]) who were examined for occlusal anomalies using dental aesthetic index (DAI). They were classified into five groups as: Visual impairment, speech and hearing disability (SH), physical disability, mentally subnormal and multiple disabilities (MD). Chi-square test was used to compare the orthodontic treatment need among various SHCN groups. One-way ANOVA and ANCOVA were performed to test any significant differences in mean DAI scores among the SHCN groups. Results: None of the children were undergoing or had undergone orthodontic treatment for malocclusion. Mean DAI score was 28.81 ± 11.64 (SD). Orthodontic treatment was indicated in 50.2% of study population who had DAI scores of 26 and above. Mandatory orthodontic treatment (DAI >=36) was required in as high as 29% of MD individuals when compared to only 10% of SH individuals. Significant differences in DAI scores were found between the SHCN groups. Conclusions: The need for orthodontic treatment among SHCN individuals was found to be high. Yet, absence of any orthodontic treatment for any child points out to the fact that the dental services are highly needed in these individuals. PMID:26020038

    ABSTRACT The present study was conducted to determine the prevalence of Rhodococcus equi infection in equines of Jammu and Kashmir, India, and evaluate the zoonotic threat posed by this organism to equine owners and tourists. One hundred and forty-one samples (98 samples from adult animals ≥5 years old and 43 samples from foals less than 6 months old) were collected in duplicate from nasopharyngeal tract of equines for isolation and direct PCR. A total of 12 isolates of R. equi were recovered, of which 9 were from foals and 3 from adult animals. Therefore, the present study recorded prevalence rates of 20.93% and 3.06% among foals and adult equines respectively. The prevalence rates were found to be 25.58% and 4.08% by 16S rRNA species-specific PCR among foals and adult animals respectively. Thus, the PCR-based assay was found to be more sensitive and helped in quick detection of R. equi than the culture based method which is time consuming and laborious. However, the culture-based method is still preferred due to some limitations of PCR. The antibiogram of the isolates revealed that erythromycin and rifampicin were the most effective antimicrobials with 100% sensitivity, followed by amoxicillin (66.67%), lincomycin (58.3%) and kanamycin (58.3%). The results also revealed that resistance was highest for penicillin G (50%), followed by kanamycin (25%) and streptomycin (25%). PMID:25829867

    Recently a smallholder socio-hydrological modelling framework was proposed and deployed to understand the underlying dynamics of Agrarian Crisis in Maharashtra state of India. It was found that cotton and sugarcane smallholders whom lack irrigation and storage techniques are most susceptible to distress. This study further expands the application of the modelling framework to other crops that are abundant in the state of Maharashtra, such as Paddy, Jowar and Soyabean to assess whether the conclusions on the possible causes behind smallholder distress still hold. Further, a fieldwork will be undertaken in March 2016 in the district of Pune. During the fieldwork 50 smallholders will be interviewed in which socio-hydrological assumptions on hydrology and capital equations and corresponding closure relationships, incorporated the current model, will be put to test. Besides the assumptions, the questionnaires will be used to better understand the hydrological reality of the farm holders, in terms of water usage and storage capacity. In combination with historical records on the smallholders' socio-economic data acquired over the last thirty years available through several NGOs in the region, socio-hydrological realism of the modelling framework will be enhanced. The preliminary outcomes of a desktop study show the possibilities of a water-centric modelling framework in understanding the constraints on smallholder farming. The results and methods described can be a first step guiding following research on the modelling framework: a start in testing the framework in multiple rural locations around the globe.

    Mass media including television, internet, and newspapers influences public views about various issues by means of how it covers an issue. Newspapers have a wider reach and may affect the impact that a news story has on the reader by factors such as placement of the story within the different pages. We did a pilot study to see how two English newspapers from Mumbai, India were covering psychiatry related news stories. The study was done over a period of 3 months. We found a total of 870 psychiatry related news stories in the two newspapers over 3 months with the majority of them being covered in the main body of the newspapers. Sex-related crime stories and/or sexual dysfunction stories received the highest coverage among all the news while treatment and/or recovery related stories received very little coverage. It is crucial that the print media takes more efforts in improving reporting of psychiatry-related stories and help in de-stigmatizing psychiatry as a discipline. PMID:26816431

    The study, carried out at the Batch Annealing Furnace (BAF) shop of Cold Rolling Mill (CRM) at an integrated steel plant of India, concerns ergonomic evaluation and redesign of a manually-operated Electrical Overhead Travelling (EOT) crane cabin. The crane cabin is a complex worksystem consisting of the crane operator and twelve specific machine components embedded in a closed workspace. A crane operator has to perform various activities, such as loading and unloading of coils, setting and removal of convector plates, and routine maintenance work. Initially, an operator had to work in standing posture with bent back most of the time. Ergonomically poor design of the chair and the controls, awkward work postures, and insufficient vision angle resulting in musculoskeletal disorders (MSDs) are some of the critical problems observed.. The study, conceived as an industry-academia joint initiative, was undertaken by a design team, the members of which were drawn from both the company concerned and the institute. With the project executed successfully, a number of lessons, such as how to minimize the anthropometric mismatch, how to improve the layout of the components and controls within enclosed workspace, and how to improve work posture minimizing risk of MSDs have been learned.

    Alternative cook stoves that replace solid fuels with cleaner energy sources, such as biogas, are gaining popularity in low-income settings across Asia, Africa, and South America. Published research on these technologies focuses on their potential to reduce indoor air pollution and improve respiratory health. Effects on other cooking-related aspects, such as diets and women’s time management, are less understood. In this study, in southern India, we investigate if using biogas cook stoves alters household diets and women’s time management. We compare treatment households who are supplied with a biogas cook stove with comparison households who do not have access to these stoves, while controlling for several socio-economic factors. We find that diets of treatment households are more diverse than diets of comparison households. In addition, women from treatment households spend on average 40 min less cooking and 70 min less collecting firewood per day than women in comparison households. This study illustrates that alongside known benefits for respiratory health, using alternative cook stoves may benefit household diets and free up women’s time. To inform development investments and ensure these co-benefits, we argue that multiple dimensions of sustainability should be considered in evaluating the impact of alternative cook stoves.

    The mineral composition of a sedimentary rock is one of its most important attributes. The presence or absence of a given mineral may be a clue to the history of a rock. Beach rock is one of the types of sedimentary rock. Beach rock is a peculiar type of formation when compared to other types of rock formations. It is commonly found along the tropical and subtropical coasts. It needs intensive and extensive investigation on its formation. Beach rock samples were collected from a vast area extending from Rameswaram to Kanyakumari of South East coast of Tamilnadu, India and were subjected to i.r. studies. Qualitative analysis was carried out to determine the major and minor constituent minerals present in the samples, from the band positions or the locations of the different peaks. In addition to the band positions, the sharpness or diffuseness of bands is helpful in the identification of mineral components. The i.r. study on these beach rocks was found to be highly useful in identifying the various minerals in beach rocks.

    Nearly 95% of global burn deaths and disabilities are estimated to occur in low and middle income countries of the world. Burns are extremely common and are a major public health problem in a developing country like India. The purpose of this study was to record and evaluate the causes and the magnitude of the fatal burns retrospectively. An analysis of autopsy records revealed 2225 (10.7%) cases of burns among the total autopsies done over 5 years period (1st January 2008-27th November 2012) in the mortuary of Forensic Medicine & Toxicology, K.G.M.U., Lucknow. The majority of deaths (88.8%) occurred between 10 and 49 years of age group with a preponderance of females (87.5%). The flame burns were seen in 60.1% of the victims. The majority of burn incidents were suicidal (38.6%) in nature followed by accidental (37.3%) and homicidal (24.1%) deaths. The percentages of burns with a total body surface area (TBSA) over 50% were observed in most of the cases (82.5%). In most of the cases deaths occurred within a week (82%) and most of the victims died from septicaemia and pneumonia (43.7%) followed by neurogenic shock (28.5%). The results of this study provide the necessary information to implement programmes for health education relating to prevention of burns focusing on the domestic setting. PMID:23663899

    Sickle cell anemia, the homozygous genotype of sickle cell disease is one of the most common heritable diseases in the world. The Arab-Asian haplotype present in India is one of the least severe of all haplotypes. Many sickle cell anemia patients are now leading a symptom-free productive life due to hydroxyurea (HU) and better supportive care. Although pregnancy in sickle cell anemia patients is considered a high-risk category, it perinatal outcome is least studied, particularly among carriers of the Arab-Asian haplotype. Thus, the present prospective, randomized study was performed to assess the perinatal outcome in sickle cell anemia. Neonatal outcome such as low birth weight, perinatal mortality rate, special care newborn unit (SCNU) admission, intrauterine growth retardation (IUGR) and pre term births were significantly higher in sickle cell anemia mothers. Maternal outcome such as severe anemia, preeclampsia, vasoocclusive crisis (VOC), pulmonary complications, jaundice and blood transfusion requirements were significantly higher in sickle cell anemia mothers, which were successfully managed. Cesarian section rate was not significantly different from normal controls. Successful pregnancies were achieved in 84.44% of cases. However, we strongly recommend that pregnancies in these patients should be managed in an institutional setup. PMID:23952263

    A nation is recognized by a range of its significant historical, cultural and natural properties. These properties are generally preserved and maintained either by national administration or by private owners and charitable trusts due to higher value of their cultural inheritance and termed globally as heritage or historic sites. Heritage sites are a significant asset, a unique and irreplaceable resource which reflects a rich and diverse expression of past societies and forms an integral part of local, regional and national cultural identity. Today, heritage sites also play an important role in communication and knowledge exchange. Thus the rapidly increasing heritage tourism industry faces several challenges too. One of the challenges is that there is a segment of society who is not yet able to equally enjoy the visit to historic structures/sites and attractions, facilities and services. This paper aims to study the experience and develop understanding regarding the heritage structures/sites approached and interacted by diverse users. This study is an outcome of a hands on workshop conducted with diverse users at various historic sites in the city of Jaipur viz. at The City Palace Complex, Jaipur, Jaigarh Fort and the Haveli at Kanota near to Jaipur India.

    Objective To perform an initial qualitative comparison of the different procurement models in India to frame questions for future research in this area; to capture the finer differences between the state models through 53 process and price parameters to determine their functional efficiencies. Design Qualitative analysis is performed for the study. Five states: Tamil Nadu, Kerala, Odisha, Punjab and Maharashtra were chosen to ensure heterogeneity in a number of factors such as procurement type (centralised, decentralised or mixed); autonomy of the procurement organisation; state of public health infrastructure; geography and availability of data through Right to Information Act (RTI). Data on procurement processes were collected through key informant analysis by way of semistructured interviews with leadership teams of procuring organisations. These process data were validated through interviews with field staff (stakeholders of district hospitals, taluk hospitals, community health centres and primary health centres) in each state. A total of 30 actors were interviewed in all five states. The data collected are analysed against 52 process and price parameters to determine the functional efficiency of the model. Results The analysis indicated that autonomous procurement organisations were more efficient in relation to payments to suppliers, had relatively lower drug procurement prices and managed their inventory more scientifically. Conclusions The authors highlight critical success factors that significantly influence the outcome of any procurement model. In a way, this study raises more questions and seeks the need for further research in this arena to aid policy makers. PMID:23388196

    Mass media including television, internet, and newspapers influences public views about various issues by means of how it covers an issue. Newspapers have a wider reach and may affect the impact that a news story has on the reader by factors such as placement of the story within the different pages. We did a pilot study to see how two English newspapers from Mumbai, India were covering psychiatry related news stories. The study was done over a period of 3 months. We found a total of 870 psychiatry related news stories in the two newspapers over 3 months with the majority of them being covered in the main body of the newspapers. Sex-related crime stories and/or sexual dysfunction stories received the highest coverage among all the news while treatment and/or recovery related stories received very little coverage. It is crucial that the print media takes more efforts in improving reporting of psychiatry-related stories and help in de-stigmatizing psychiatry as a discipline. PMID:26816431

    used in this study to track flow regime and sedimentation characteristics. Data from topographical maps, cadastral or mouza maps, and satellite images has been consolidated. Significant stress has been given on extensive and intensive field survey in order to assess human perception, adaptability and resource management in the sandbars or char lands. The Damodar River is located in West Bengal, India but the findings on the controlled Lower Damodar are not exclusive to this river. These findings may help in managing water resources in other regulated rivers in India or outside India. The primary objectives of this paper have been to trace the impact of control measures on discharge, sedimentation characteristics and consequent changes in the perception and adjustment of the riverbed occupiers to life with floods and dams. In this age of heightened environmental awareness, we all know that the survival of our civilization depends on rational and constructive maintenance and use of our river resources. The major challenge in the coming decade is to develop a holistic and sustainable river management system that will be environmentally accountable, socially acceptable and economically feasible. The primary issue to be addressed, therefore, is not whether dams are needed but how a river system is cared for in the presence of floods, dams and islanders. River resources should be treated as economic assets since ongoing economic development depends on a riverine regime that is ecologically sound. These worthwhile goals, however, will remain out of reach unless we have effective government policy and the legal structure to support it.

    2012-12-01

    Magnetic and gravity investigations were undertaken in Mono Lake, California to study regional crustal structures and to aid understanding the geologic framework of Mono Lake, in particular regarding potential geothermal resources and volcanic hazards throughout Mono Basin. Recent geophysical surveys included over 600 line-kilometers of high-resolution ship-borne magnetometer data that augmented existing airborne data, 22 line-kilometers of ground magnetic data that were collected along six traverses across Paoha Island, 56 gravity stations that were collected on Paoha and Negit Islands, and 28 rock samples that were collected for physical property data. Magnetic highs in the study area occur to the east and west of Mono Lake, where pre-Tertiary basement is exposed. Magnetic data indicate that Mono Lake itself is dominated by three prominent magnetic anomalies that are from west to east: a magnetic high along the northwest part of the lake associated with the moderately magnetic basalt cinder cone at Black Point, a magnetic high associated with the young volcanic centers at Paoha and Negit Islands, and a broad magnetic high along the eastern margin of the lake probably associated with moderately magnetic granitic basement rocks at depth. Because volcanic rocks exposed at the surface of Paoha and Negit Islands are only weakly magnetic, magnetic data suggest that more mafic volcanic rocks probably occur at depth and are the source of the anomaly. The linear and steep magnetic gradient across the eastern part of the lake may reflect a fault. A fault may also be imaged in the northeastern part of the lake, where a possible laterally offset magnetic anomaly may be present. Within Mono Lake, gravity station control is poor because land-based gravity stations are limited to Paoha and Negit Islands. The gravity low in the basin reflects a moderately deep sedimentary basin filled with low density lacustrine and volcanic deposits. Isostatic gravity data indicate the central

    Objectives We sought to estimate the proportion of adults in Sehore District, India, who consumed alcohol, and the proportion who had behaviours consistent with alcohol use disorders (AUDs), using the Alcohol Use Disorders Identification Test (AUDIT). Among men who drank, we identified individual-level, household-level and community-level factors associated with AUDIT scores. Men with AUDs (AUDIT score ≥8) reported on whether and where they had sought treatment, and about alcohol-related internal stigma. Design Population-based cross-sectional study. Setting Rural villages and urban wards in Sehore District, Madhya Pradesh, India. Participants n=3220 adult (≥18 years of age) residents of Sehore District. Primary outcome measure Score on the AUDIT. Results Nearly one in four men (23.8%) had consumed alcohol in the past 12 months, while few (0.6%) women were consumers. Among drinkers, 33.2% (95% CI 28.6% to 38.1%) had AUDIT scores consistent with hazardous drinking, 3.3% (95% CI 2.1% to 5.1%) with harmful drinking and 5.5% (95% CI 3.8% to 8.0%) with dependent drinking. We observed that AUDIT scores varied widely by village (intraclass correlation=0.052). Among men who had recently consumed alcohol, AUDIT scores were positively associated with depression, having at least one child, high-quality housing, urban residence, tobacco use and disability. AUDIT scores were negatively associated with land ownership, out-of-pocket healthcare expenditure and participation in the national employment programme. While 49.2% of men with AUDs felt embarrassed by their problems with alcohol, only 2.8% had sought treatment in the past 12 months. Conclusions A need exists for effectively identifying and treating adults with AUDs. Health promotion services, informed by commonly-expressed stigmatised beliefs held among those affected by AUDs and which are targeted at the most affected communities, may be an effective step in closing the treatment gap.

    Background: Out of eight commonly agreed Millennium Development Goals (MDG), six are related to the attainment of Universal Health Coverage (UHC) throughout the globe. This universalization of health status suggests policies to narrow the gap in access and benefit sharing between different socially and economically underprivileged classes with that of the better placed ones and a consequent expansion of subsidized healthcare appears to be a common feature for most of the developing nations. The National Health Policy in India (2002) suggests expansion of market-based care for the affording class and subsidized care for the deserving class of the society. So, the benefit distribution of this limited public support in health sector is important to examine to study the welfare consequences of the policy. This paper examines the nature of utilization to inpatient care by different socio-economic groups across regions and gender in West Bengal (WB), India. The benefit incidence of public subsidies across these socio-economic groups has also been verified for different types of services like medicines, diagnostics and professional care etc. Methods: National Sample Survey Organization (NSSO) has collected information on all hospitalized cases (60th round, 2004) with a recall period of 365 days from the sampled households through stratified random sampling technique. The data has been used to assess utilization of healthcare services during hospitalization and the distribution of public subsidies among the patients of different socio-economic background; a Benefit Incidence Analysis (BIA) has also been carried out. Results: Analysis shows that though the rate of utilization of public hospitals is quite high, other complementary services like medicine, doctor and diagnostic tests are mostly purchased from private market. This leads to high Out-of-Pocket (OOP) expenditure. Moreover, BIA reveals that the public subsidies are mostly enjoyed by the relatively better placed

    The Government of India initiated a cash incentive scheme--Janani Suraksha Yojana (JSY)--to promote institutional deliveries with an aim to reduce maternal mortality ratio (MMR). An observational study was conducted in a tertiary-care hospital of Madhya Pradesh, India, before and after implementation of JSY, with a sample of women presenting for institutional delivery. The objectives of this study were to: (i) determine the total number of institutional deliveries before and after implementation of JSY, (ii) determine the MMR, and (iii) compare factors associated with maternal mortality and morbidity. The data were analyzed for two years before implementation of JSY (2003-2005) and compared with two years following implementation of JSY (2005-2007). Overall, institutional deliveries increased by 42.6% after implementation, including those among rural, illiterate and primary-literate persons of lower socioeconomic strata. The main causes of maternal mortality were eclampsia, pre-eclampsia and severe anaemia both before and after implementation of JSY. Anaemia was the most common morbidity factor observed in this study. Among those who had institutional deliveries, there were significant increases in cases of eclampsia, pre-eclampsia, polyhydramnios, oligohydramnios, antepartum haemorrhage (APH), postpartum haemorrhage (PPH), and malaria after implementation of JSY. The scheme appeared to increase institutional delivery by at-risk mothers, which has the potential to reduce maternal morbidity and mortality, improve child survival, and ensure equity in maternal healthcare in India. The lessons from this study and other available sources should be utilized to improve the performance and implementation of JSY scheme in India. PMID:23304913

    Evidence regarding the relationship between married women's autonomy and risk of marital violence remains mixed. Moreover, studies examining the contribution of specific aspects of women's autonomy in influencing the risk of marital violence using measures of autonomy that incorporate its dynamic nature are rare. We investigated the relationship between women's autonomy and their experience of marital violence in rural India using prospective data. We used data on 4,904 rural women drawn from two linked studies: the NFHS-2, conducted during 1998-1999 and a follow-up study for a subgroup of women carried out during 2002-2003. Three dimensions of autonomy were used: financial autonomy, freedom of movement, and household decision-making. Marital violence was measured as experience of physical violence in the year prior to the follow-up survey. Findings indicate the protective effects of financial autonomy and freedom of movement in reducing the risk of marital violence in the overall model. Furthermore, region-wise analysis revealed that in the more gender equitable settings of south India, financial autonomy exerted a protective influence on risk of marital violence. However, in the more gender-stratified settings of north India, none of the dimensions of autonomy were found to have any protective effect on women's risk of marital violence. Results argue for an increased focus on strategies aimed at improving women's financial status through livelihood skill-building opportunities, development of a strong savings orientation, and asset-building options.

    Natural radiation is the largest contributor to the collective radiation dose of the world population. It is widely distributed in different geological formations such as soil, rocks, air and groundwater. In the present investigation, (226)Ra, (232)Th and (40)K were measured in soil samples of the Ukhimath region of Garhwal Himalaya, India using NaI(Tl) gamma-ray spectrometry. The activity concentrations of naturally occurring radionuclides (226)Ra, (232)Th and (40)K were found to vary from 38.4 ± 6.1 to 141.7 ± 11.9 Bq kg(-1) with an average of 80.5 Bq kg(-1), 57.0 ± 7.5 to 155.9 ± 12.4 Bq kg(-1) with an average of 118.9 Bq kg(-1) and 9.0 ± 3.0 to 672.8 ± 25.9 Bq kg(-1) with an average of 341 Bq kg(-1), respectively. The total absorbed gamma dose rate varies from 70.4 to 169.1 nGy h(-1) with an average of 123.4 nGy h(-1). This study is important to generate a baseline data of radiation exposure in the area. Health hazard effects due to natural radiation exposure are discussed in details. PMID:22908360

    This study has been undertaken to examine the occurrence of climate change in Tamil Nadu, the southernmost state of India and its impact on rainfall pattern which is a primary constraint for agricultural production. Among the five sample stations examined across the state, the minimum temperature has increased significantly in Coimbatore while the same has decreased significantly in Vellore whereas both minimum and maximum temperatures have increased significantly in Madurai since 1969 with climate change occurring between late 1980s and early 1990s. As a result, the south-west monsoon has been disturbed with August rainfall increasing with more dispersion while September rainfall decreasing with less dispersion. Thus, September, the peak rainfall month of south-west monsoon before climate change, has become the monsoon receding month after climate change. Though there has been no change in the trend of the north-east monsoon, the quantity of October and November rainfall has considerably increased with increased dispersion after climate change. On the whole, south-west monsoon has decreased with decreased dispersion while north-east monsoon has increased with increased dispersion. Consequently, the season window for south-west monsoon crops has shortened while the north-east monsoon crops are left to fend against flood risk during their initial stages. Further, the incoherence in warming, climate change and rainfall impact seen across the state necessitates devising different indigenous and institutional adaptation strategies for different regions to overcome the adverse impacts of climate change on agriculture.

    Objective: To describe clinical, electrophysiological, and histopathological profile of vasculitic neuropathy in elderly subjects aged 65 years or more. Design: Retrospective chart review. Setting: Departments of Neurology and Neuropathology, National Institute of Mental Health and Neurosciences, Bengaluru, Karnataka, India. Patients and Methods: Elderly subjects, diagnosed vasculitic neuropathy by nerve biopsy over one decade, were studied. Results: The cohort consisted of 46 subjects. Symptom duration was 21.54 ± 33.53 months. Onset was chronic in majority (82.6%). Key features included paresthesias (89%), weakness (80%), sensory loss (70%), wasting (63%), and relapsing-remitting course (6.5%). Most Common clinico-electrophysiological patterns were distal symmetrical sensorimotor polyneuropathy - 19, mononeuritis multiplex - 9, and asymmetric sensorimotor neuropathy - 10. Diagnosis of vasculitis was not suspected before biopsy in 31 (67.3%). Nerve biopsy revealed definite vasculitis - 12, probable - 10, and possible - 24. Treatment included immunomodulatory agents (41), symptomatic medications only (9), and antiretroviral therapy (1). Twenty-four patients were followed up for mean period of 6.5 months. Outcome at last follow-up was improved (13), unchanged (8), and worsened (3). Conclusion: Vasculitis is an important, treatable cause of neuropathy in elderly. Nerve biopsy should be used judiciously for early diagnosis and appropriate treatment.

    Long term variations of middle atmospheric thermal structure in the upper stratosphere and lower mesosphere (20 km to 90 km) have been studied over Ahmedabad (23.1o N, 72.3o E, 55 m amsl), India using SABER (Sounding of the Atmosphere using Broadband Emission Radiometry) onboard TIMED (Thermosphere, Ionosphere, Mesosphere, Energetics and Dynamics)observations during year 2002 to year 2014. For the same period, three different atmospheric models show over-estimation of temperature (~10 K) in stratopause and in upper mesosphere, and a signature of under-estimation is seen above mesopause when compared against SABER measured temperature profile. Estimation of monthly temperature anomalies reveals a downward trend of lower temperature from mesosphere to stratosphere during January to December. Moreover, Lomb Scargle periodogram (LSP) and Wavelet transform techniques are employed to characterize the semi-annual, annual and quasi-biennial oscillations to diagnose the wave dynamics in the stratosphere-mesosphere system. Results suggested that semi-annual, annual and quasi-biennial oscillations are exist in stratosphere, whereas, semi-annual and annual oscillations are observed in mesosphere. In lower mesosphere, LSP analyses revealed conspicuous absence of annual oscillations in altitude range of ~55 to 65 km, and semi-annual oscillations are not exist in 35 to 45 km. Four monthly oscillations are also reported in the altitude range of about 45 to 65 km.The temporal localization of oscillations using wavelet analysis shows strong annual oscillation during year 2004-2006 and 2009-2011.

    {open_quotes}Rootfuel,{close_quotes} made by drying the fast-growing starchy-cellulosic taproots of certain members of the family Cucurbitaceae, has been under investigation by us since 1985. Rootfuel can be quickly dried to a much lower level of moisture content than seasoned wood, and also unlike wood, it contains a very small amount of lignin. If it is dry and burned with good draft, it can be burned more slowly than wood with very little smoke production. We studied rootfuel made from Cucurbita foetidissima roots in dry, deforested and well-populated rural lands of Mexico, Brazil, Zimbabwe and India under sponsorship of the Biomass Users Network, with funding from the Rockefeller Foundation. Our purpose was to evaluate rootfuel as a replacement for wood, dung and crop residues to improve indoor air quality for health reasons, and to take pressure off of the remaining trees. Acceptability has been uniformly high. Small test plots have been planted, and new rootfuel species have been identified and tested.

    Chemotherapy and emergence of drug resistance strains of Staphylococcus aureus is receiving serious threats, due to the origin and spread of hospital and community acquired MDR strains. The present study reports the prevalence of antibiotic resistance among Staphylococcus aureus isolated from clinical samples from different cities of India. Antibiotic sensitivity was performed by Kirby-Bauer disk diffusion method and minimum inhibitory concentrations were determined for vancomycin and methicillin according to CLSI (2014) guidelines. A total of 212 S. aureus were obtained from different samples such as pus, blood, urine. The antibiogram of these isolates indicated widespread resistance to various groups of antibiotics ranging from a minimum of 10.13% against Phenicols (Chloramphenicol) to a maximum of 97% against Penicillin and 44.8% isolates were MRSA and alarmingly 10.84% were VRSA. Most of the MRSA isolates showed inducible Clindamycin resistance. Widespread prevalence of MDR patterns, increasing incidence of MRSA and VRSA calls for exploration of alternative medicines and new approaches to combat Staphylococcal infections. PMID:27448836

    The healthcare service scenario in India is expected to evolve into a more developed stage. More emphasis has been given on patient satisfaction as this is an important consideration for the assessment of the hospital services. The concept of patient satisfaction is also rapidly changing and the hospitals are using variety of techniques to improve patient care and organizational efficiency. Patient satisfaction questionnaire is a validated instrument to assess the level of the satisfaction of adult patients. The questionnaire was administered on those patients who were admitted in hospital for at least three days. In our study 88% patients were satisfied with treatment and medical care they had received. About 86% patients found that the hospital services were excellent. However, it is felt that patient values and culture should be explored for further improving patient doctor communication. There is hence a scope for improvement in meeting patient's needs and preferences and rendering hospital services. This can be achieved by some feedback system which could be available to the patients and later worked upon by the management, to improve the patient care by bridging the gap between senior management and patients.

    Commuters' exposure to volatile organic compounds (VOCs) especially BTEX travelling in passenger cars in Kolkata, India were quantified in Phase I (2001-2002) and Phase II (2003-2004). Monitoring was made inside and in the immediate outside of passenger cars fitted with and without catalytic converters using different types of fuels, along two congested urban routes. During Phase I of the study, the benzene content in gasoline was 5% and the mean concentration of in-vehicle benzene in cars without catalytic converter was found to be as high as 721.2 microg/m3. In Phase II when the benzene content was reduced to <3% and with modified engine type, the mean in-vehicle benzene concentration was reduced to 112.4 microg/m3. The in-vehicle concentration varied with engine type and age of the vehicle. Roadside ambient mean concentration of benzene was 214.8 microg/m3 and 30.8 microg/m3 in Phase I and Phase II respectively. PMID:17113131

    The damage caused to underwater timber construction in Marine environment by Molluscan and Crustaceans borers is well known and is of great economic significance to all maritime countries having an expanding shipping and fishing industry. Biodeterioration of marine structure, fishing crafts and living in mangrove vegetation is quite severe along the Karwar coast. The destruction is caused by atleast 14 species and 1 variety of borers belonging to the moluscan and crustacean families of the Teredinidae, Pholadidae and Sphaeromatidae. The following species have been so far recorded: Dicyathifer manni, Lyrodus pedicellaatus, L.Massa, Bankia rochi, B. campanellata, Mausitora hedleyi,Martesia striata, M.NMairi,Sphaeroma terebrans, S.annandalei, S. annandalei travancorensis. These borers, particularly, the molluscs have prodigenous fecundity producing enormous number of young ones in one brood. They have unlimited appetite attacking any type woodly materials exposed in the sea. They attack in heavy intensity and, because of their fast rate of growth, destroy timber with in a short time of few months. All this together with their other highly specialized. Adaptations make marine wood borers man's number one enemy in the sea. Along Karwar costs borer damage to timber structure is heavy throughout the year, highest in September to November and lowest in June and July. Ecological and biological aspects of the borers are also discussed. Ref: L.N.Shantakumaran, Sawant S.G., Nair N.B., Anil Angre, Nagabhushanan R.

    The IPCC Fifth Assessment Report concluded, "More than half of the observed increase in global mean surface temperature (GMST) from 1951 to 2010 is very likely due to the observed anthropogenic increase in greenhouse gas (GHG) concentrations." Detecting and attributing the changes over regional scales can provide more relevant information to policymakers at the national level but the low signal-to-noise ratios at smaller spatial scales make this a harder problem. In this study, we analyze annual and seasonal mean changes in minimum (Tmin), maximum (Tmax), and mean (Tmean) temperatures over 7 homogeneous temperature zones of India using models from the CMIP5 database and multiple observational datasets (CRU-3.22, and IITM). We perform Detection and Attribution (D&A) analysis using fingerprint methods by defining a signal that concisely express both spatial and temporal changes found in the model runs with the CMIP5 individual forcing runs; greenhouse (historicalGHG), natural (historicalNat), anthropogenic (historicalAnthro), and anthropogenic aerosols (historicalAA). We use three different combinations of individual forcing patterns (2-pattern, 3-pattern and 5-pattern cases) in our analysis to quantify the contributions resulting from individual forcings. Results indicate warming attributable in most regions to anthropogenic forcings and Greenhouse gases with a negligible contribution from natural forcings using the 2- and 3-pattern analyses for the 1901-2005 and 1956-2005 time periods. The results are sensitive to observational data set used, as these tend to differ at the regional level.

    Geological lineaments or `geolineaments', irrespective of their hydrological nature, are generally treated as a single class, and density of geolineaments is considered as a key hydrogeological factor influencing infiltration and recharge. However, all natural linear features do not behave alike in different hydrological events such as recharge and discharge. Considering this, the described study examines the role and influence of different types of geolineaments on the groundwater regime in the semi-arid crystalline Aravalli terrain of western India. Geolineaments have been classified with the aid of published geological maps, satellite imagery and selected field verification. Graphical analysis and statistical tests have revealed significant differences in the nature, role and efficiency of various geolineaments in terms of recharge and productivity. With respect to water-level fluctuation representing recharge and well productivity depicting discharge, reversal in hydrological efficiency is noticed for drainage lines (straight versus curvilinear), fold axes (antiformal versus synformal) and faults (vertical-slip versus lateral-slip). Analysis and comparison has revealed that the associated geological structures and their geometry, and hydraulic properties of the aquifers (vadose zone and saturated zone), are the key factors for the different nature, roles and efficiency of various geolineaments.

    We evaluated the spectrum of hemoglobinopathies among the primitive tribal groups from 4 states in India. A total of 15,200 individuals from 14 primitive tribal groups were studied by automated high-performance liquid chromatography. The hemoglobin S (HbS) allele frequency varied from 0.011 to 0.120 and the β-thalassemia allele frequency from 0.005 to 0.024. It is interesting to note that a very high HbS allele frequency was observed among the Dravidian (0.060-0.120) and Indo-European (0.060-0.076) as compared with Austro-Asiatic (0.011-0.022) speaking tribal groups. Although statistical analysis of the data did not show any ethnic differences within the states, regional differences were observed between the states for both HbS and β-thalassemia traits. HbS was found to be the most common hemoglobinopathy followed by β-thalassemia. A health plan for identifying sickle-cell homozygotes in the neonatal period with proper medical intervention is desirable. PMID:23513007

    Studies have documented the substantial risk of human immunodeficiency virus (HIV) infection endured by sex-trafficked women, but it remains unclear how exposure to trafficking puts its victims at risk. We assessed whether the association between sex trafficking and HIV could be explained by self-reported forced prostitution or young age at entry into prostitution using cross-sectional data collected from 1,814 adult female sex workers in Karnataka, India, between August 2005 and August 2006. Marginal structural logistic regression was used to estimate adjusted odds ratios for HIV infection. Overall, 372 (21%) women met 1 or both criteria used to define sex trafficking: 278 (16%) began sex work before age 18 years, and 107 (5%) reported being forcibly prostituted. Thirteen (0.7%) met both criteria. Forcibly prostituted women were more likely to be HIV-infected than were women who joined the industry voluntarily, independent of age at entering prostitution (odds ratio = 2.30, 95% confidence interval: 1.08, 4.90). Conversely, after adjustment for forced prostitution and other confounders, no association between age at entry into prostitution and HIV was observed. The association between forced prostitution and HIV infection became stronger in the presence of sexual violence (odds ratio = 11.13, 95% confidence interval: 2.41, 51.40). These findings indicate that forced prostitution coupled with sexual violence probably explains the association between sex trafficking and HIV. PMID:23324332

    In Active Galactic Nuclei (AGN) the luminosity is so intense that the effect of radiation pressure on a particle may exceed the gravitational attraction. It was shown that when such luminosities are reached, relatively cold (not completely ionized) thermal matter clouds may form in the central engines of AGN, where most of the luminosity originates. We show that the spectrum of emission from cold clouds embedded in hot relativistic matter is similar to the observed spectrum. We also show that within the hot relativistic matter, cold matter moves faster than the speed of sound or the Alfven speed, and shocks form. The shocks provide a mechanism by which a localized perturbation can propagate throughout the central engine. The shocked matter can emit the observed luminosity, and can explain the flux and spectral variability. It may also provide an efficient mechanism for the outward transfer of angular momentum and provide the outward flow of winds. With observations from X-ray satellites, emission features from the cold and hot matter may be revealed. Our analysis of X-ray data from the Seyfert 1 galaxy MCG - 6-30-15 over five years using detectors on the Ginga and Rosat satellites, revealed some interesting variable features. A source with hot matter emits non-thermal radiation which is Compton reflected from cold matter and then absorbed by warm (partially ionized) absorbing matter in the first model, which can be fit to the data if both the cold and warm absorbers are near the central engine. An alternative model in which the emission from the hot matter is partially covered by very warm matter (in which all elements except Iron are mostly ionized) is also successful. In this model the cold and warm matter may be at distances of up to 100 times the size of the central engine, well within the region where broad optical lines are produced. The flux variability is more naturally explained by the second model. Our results support the existence of cold matter in, or

  1. Using Ecological Momentary Assessment to Study Tobacco Behavior in Urban India: There’s an App for That

    2015-01-01

    Background Ecological momentary assessment (EMA) uses real-time data collection to assess participants’ behaviors and environments. This paper explores the strengths and limitations of using EMA to examine social and environmental exposure to tobacco in urban India among older adolescents and adults. Objective Objectives of this study were (1) to describe the methods used in an EMA study of tobacco use in urban India using a mobile phone app for data collection, (2) to determine the feasibility of using EMA in the chosen setting by drawing on participant completion and compliance rates with the study protocol, and (3) to provide recommendations on implementing mobile phone EMA research in India and other low- and middle-income countries. Methods Via mobile phones and the Internet, this study used two EMA surveys: (1) a momentary survey, sent multiple times per day at random to participants, which asked about their real-time tobacco use (smoked and smokeless) and exposure to pro- and antitobacco messaging in their location, and 2) an end-of-day survey sent at the end of each study day. Trained participants, from Hyderabad and Kolkata, India, reported on their social and environmental exposure to tobacco over 10 consecutive days. This feasibility study examined participant compliance, exploring factors related to the successful completion of surveys and the validity of EMA data. Results The sample included 205 participants, the majority of whom were male (135/205, 65.9%). Almost half smoked less than daily (56/205, 27.3%) or daily (43/205, 21.0%), and 4.4% (9/205) used smokeless tobacco products. Participants completed and returned 46.87% and 73.02% of momentary and end-of-day surveys, respectively. Significant predictors of momentary survey completion included employment and completion of end-of-day surveys. End-of-day survey completion was only significantly predicted by momentary survey completion. Conclusions This first study of EMA in India offers promising

    Based on their interaction with solar radiations, aerosols may be categorized as absorbing or scattering in nature. The absorbing aerosols are coarser and influence precipitation mainly due to microphysical effect (participating in the formation of Cloud Condensation Nuclei) and radiative forcing (by absorbing electromagnetic radiations). The prominent absorbing aerosols found in India are Black Carbon, soil dust, sand and mineral dust. Their size, distribution, and characteristics vary spatially and temporally. This paper aims at showing the spatio-temporal variation of Absorbing Aerosol Index (AAI) and precipitation over the four most polluted zones of Indian sub-continent (Indo-Gangetic plains 1, Indo-Gangetic plains 2, Central and Southern India) for monsoon season (June, July, August, September) during the last decade (2005 to 2014). Zonal averages AAI have been found to be exhibiting an increasing trend, hence region-wise correlations have been computed between AAI and precipitation during monsoon. Daily Absorption Aerosol Index (AAI) obtained from Aura OMI Aerosol Global Gridded Data Product-OMAEROe (V003) and monthly precipitation from TRMM 3B42-V7 gridded data have been used.

    There is little qualitative research on depression in motherhood from non-Western societies. The objective of the study described in this paper was to use qualitative methods to investigate the cultural validity of the construct of post-natal depression (PND) and its social and cultural contexts. The study was nested in a cohort of mothers recruited to study the risk factors and outcome of PND in Goa, India. In-depth interviews were carried out with 39 mothers (19 of whom were found to be suffering from PND as defined by a cut-off score on the Edinburgh PND scale) and their husbands purposively recruited from the cohort. An illness narrative was conducted with mothers who were categorized as suffering from PND and their husbands to elicit their explanatory models. The two groups (PND and non-PND) of mothers were comparable in terms of socio-demographic characteristics. PND mothers had lower levels of practical help and emotional support. The symptoms reported by PND mothers were similar to those recorded in studies with women in other cultures suggesting a universal clinical presentation of PND. Causal attributions for the experience of depression focused on economic difficulties and poor marital relationship. All mothers expressed the need for more practical help and support during the period after childbirth; husbands in both groups were often disengaged from baby care or supporting the mother. The study provides validity for the construct of PND in an Indian setting, but also shows that the emotional distress is interpreted from the context of social adversity, poor marital relationships and cultural attitudes towards gender rather than a biomedical psychiatric category. Contrary to the assumption that socio-cultural contexts associated with childbirth in non-Western societies protect mothers from depression, factors unique to the culture such as gender preference and the low involvement of husbands in child-care are major causes of stress to mothers.

    The present work was aimed at the establishment of baseline radioactive data in the proposed Lambapur and Peddagattu uranium mining areas in the Andhra Pradesh state, India. The background concentrations of naturally occurring radioactivity in the near-surface soils of the study areas were estimated and the results were analysed. The (238)U concentration in the near-surface soil of the study area was found to vary from 100 to 176 Bq kg(-1), with a mean of 138±24 Bq kg(-1). (232)Th in the study area soils was found to vary between 64 and 116 Bq kg(-1), with a mean of 83±15 Bq kg(-1). The (40)K concentration was found to vary between 309 and 373 Bq kg(-1), with a mean of 343±20 Bq kg(-1). The mean natural background radiation levels were also measured with thermoluminescence (TL) dosimetry technique and with a µR-survey meter, in the villages of the study area. Dose rates measured by TL are found to vary from 1287 to 3363 μGy y(-1), with a mean of 2509 ± 424 μGy y(-1). The dose rates measured in the same villages with a μR-survey meter were found to be in the range of 1211-3255 μGy y(-1), with a mean of 2524 ± 395 μGy y(-1). The mean radiation levels in the study area are found to be relatively high when compared with (Indian) national and international averages. Correlations among radon, thoron and gamma dose rates were found to be poor. The pre-operational data produced in this work will be useful for comparison with future radiation levels during the proposed uranium mining operations. PMID:22319131

    Aims: To obtain information on organizational aspects, case mix and practices in Indian Intensive Care Units (ICUs). Patients and Methods: An observational, 4-day point prevalence study was performed between 2010 and 2011 in 4209 patients from 124 ICUs. ICU and patient characteristics, and interventions were recorded for 24 h of the study day, and outcomes till 30 days after the study day. Data were analyzed for 4038 adult patients from 120 ICUs. Results: On the study day, mean age, Acute Physiology and Chronic Health Evaluation (APACHE II) and sequential organ failure assessment (SOFA) scores were 54.1 ± 17.1 years, 17.4 ± 9.2 and 3.8 ± 3.6, respectively. About 46.4% patients had ≥1 organ failure. Nearly, 37% and 22.2% patients received mechanical ventilation (MV) and vasopressors or inotropes, respectively. Nearly, 12.2% patients developed an infection in the ICU. About 28.3% patients had severe sepsis or septic shock (SvSpSS) during their ICU stay. About 60.7% patients without infection received antibiotics. There were 546 deaths and 183 terminal discharges (TDs) from ICU (including left against medical advice or discharged on request), with ICU mortality 729/4038 (18.1%). In 1627 patients admitted within 24 h of the study day, the standardized mortality ratio was 0.67. The APACHE II and SOFA scores, public hospital ICUs, medical ICUs, inadequately equipped ICUs, medical admission, self-paying patient, presence of SvSpSS, acute respiratory failure or cancer, need for a fluid bolus, and MV were independent predictors of mortality. Conclusions: The high proportion of TDs and the association of public hospitals, self-paying patients, and inadequately equipped hospitals with mortality has important implications for critical care in India.

    Introduction Helicobacter pylori (H.pylori) are of major concern today because of its causal relationships with gastrointestinal diseases. It represents one of the most common and medically important infections worldwide. H.pylori plays a key role in the aetiology of chronic gastritis, duodenal ulcer, gastric carcinoma and MALT lymphoma. There is paucity of literature regarding the morphological changes in H.pylori associated gastritis. Aim We undertake this study to find out the association and prevalence of H.pylori associated gastritis by histopathological methods in North Maharashtra, India. Materials and Methods A total 310 patients with various upper gastrointestinal disorders were included in this study over the period of 19 months from July 2013 to January 2015. The detailed clinical history was taken and patients were subjected to video gastroscopy. Each biopsy was studied with Haematoxylin and Eosin/Giemsa method. Results The prevalence of H.pylori was high in third to fourth decades. Out of 310 patients of gastrocopy, 144 were H.pylori positive by Haematoxylin and Eosin/Giemsa method. Morphological changes specific for H.pylori was noted as atrophy and irregular gastric mucosa, lymphoid aggregates and reactive atypia. Male patient were outnumbered by female patients. Conclusion Histopathological evaluation is the gold standard for diagnosing H.pylori infection. Prevalence of H.pylori in the present study was 46.5% in patients undergoing videogastroscopic biopsies for gastritis and vague upper gastrointestinal symptoms. Furthermore and large scale studies are required to establish the diagnostic modalities for H.pylori associated gastritis to prevent morbidity and mortality. PMID:26266125

    Objective To evaluate the effects of an intervention comprising surveillance and an organisational change called Appreciative Inquiry on puerperal infections in hospitals in Gujarat state, India. Methods This longitudinal cohort study with a control group was conducted over 16 months between 2010 and 2012. Women who delivered in six hospitals were followed-up. After a five month pre-intervention period, the intervention was introduced in three hospitals. Monthly incidence of puerperal infection was recorded throughout the study in all six hospitals. A chi-square test and logistic regression were used to examine for associations, trends and interactions between the intervention and control groups. Findings Of the 8,124 women followed up, puerperal infections were reported in 319 women (3.9%) over the course of the study. Puerperal sepsis/genital tract infections and urinary tract infections were the two most common puerperal infections. At the end of the study, infection incidence in the control group halved from 7.4% to 3.5%. Levels in the intervention group reduced proportionately even more, from 4.3% to 1.7%. A chi-square test for trend confirmed the reduction of infection in the intervention and control groups (p<0.0001) but the trends were not statistically different from one another. There was an overall reduction of infection by month (OR = 0.94 95% CI 0.91–0.97). Risk factors like delivery type, complications or delivery attendant showed no association with infection. Conclusion Interruption of resource flows in the health system occurred during the intervention phase, which may have affected the findings. The incidence of infection fell in both control and intervention groups during the course of the study. It is not clear if appreciative inquiry contributed to the reductions observed. A number of practical and methodological limitations were faced. Trial Registration Controlled-Trials.com ISRCTN03513186 PMID:24498089

    Background Salt workers are exposed to occupational hazards like contact with salt crystals and brine, physical stress, sunlight and glare due to sunlight reflected by salt crystals. Very few studies have documented the morbidity among the salt workers. Aim To assess the morbidity pattern among salt workers in Marakkanam, Tamil Nadu, India. Materials and Methods A community based cross-sectional study was undertaken in 4 randomly selected salt worker villages. Three hundred thirty one salt workers were reached by a house-to-house survey during April 2010 to March 2011. Demographic data was collected; clinical examination was conducted using a predesigned and pretested questionnaire. A pilot study was conducted to estimate the prevalence of morbidity before initiating the study. The data was analyzed using SPSS Version 11.5. Chi-square test and odds ratios (OR) with 95% confidence intervals (CI) were calculated to determine the association of morbidity levels with various factors. Results Of the 331 salt workers in the study, 58% were females, mean age was 41.9 ± 10.8 y. Eighty seven percent salt workers had some or other morbidity. The observed morbidities include clinical pallor (44.4%), ocular morbidities including cataract, pterygium, conjunctivitis, pingecula and corneal ulcer (42%), caries teeth (41.7%), hypertension (23.3%), underweight (19.3%), goiter (19%), obesity (14.8%) and dermal conditions including dermatitis, thickening of palm and sole, tinea unguum, follicultitis (9.1%). The presence of morbidity did not show any significant association with increase in age, gender, duration of employment or the type of salt work involved with. However, the lower the education level, the higher is the morbidity level among salt workers (OR = 5.23, 95% CI= 2.07 to 13.21) Conclusion Morbidity among salt workers is high. Intervention programs are needed to alleviate the health problems in the salt workers. PMID:26023571

    The radiation dose received by man from indoor radon and its progeny is the largest at more than 50% of total dose received. The seasonal variation of indoor radon concentration in Kerala, India and Kuala Lumpur, Malaysia were studied. The Southwest coast of the Kerala state in India is known to have very high levels of natural background radiation owing to the rare earths rich monazite sand available in large amount. Kuala Lumpur, Malaysia used to be a famous tin mining area where it was done using open cast system. One-year measurements of radon concentration in houses were done for these two regions. It was found that there is considerable seasonal variation in the levels of radon in Kerala but the variation in Kuala Lumpur is only less than 10%.

    Twenty-one cases (12 males, 9 females) of Lafora's disease in 16 families were studied at the National Institute of Mental Health and Neuro Sciences (NIMHANS), Bangalore, India, from 1982 to 1990. Mean age of onset was 13.5 years (range 9.5-18 years). First symptom was generalized tonic-clonic seizure (17), myoclonus (3), or dementia (1). All patients eventually developed the classical triad, except 1 who has had only myoclonus. Seven had occipital seizures. Other signs included behavioral changes (9), brisk tendon reflexes (11), cerebellar signs (8), and visual impairment (4). Patients from 14 of the 16 families (85%) were products of consanguineous marriage. More than 1 sibling was affected in 6 families. Scalp EEGs showed diffuse background slowing with epileptiform discharges in all and progressive slowing as the disease progressed in 3. Photosensitivity occurred in 4 of the 17 cases studied (23.5%). EEG abnormalities were documented in the presymptomatic stage in 2 cases 6 months and 6 years before clinical symptom onset. Visual evoked responses were abnormal in 4 of the 6 cases studied. Giant somatosensory evoked potentials (SSEP) were observed in all 8 cases studied. Lafora bodies were demonstrated in axillary skin in 14 of 17 (82.4%), in liver in 4 of 10 (40%), and in both brain biopsy specimens. In 2 cases, liver biopsy was positive while axillary skin biopsy was negative. In the brain, inclusions were evident in glial and capillary endothelial cells in addition to neurons. Although our cases were similar to those described earlier, the relative rarity of visual phenomena is emphasized. The clinical pattern was consistent with autosomal recessive inheritance. The high frequency of consanguinity in the South Indian population may be responsible for the many cases observed at our center. PMID:8389290

    Context: Periodic systematic profiling of suicidal risk factors in developing countries is an established need. Aims: It was intended to study the risk factors associated with suicide attempts in Orissa, one of the most economically compromised states of India. Settings and Design: Cross-sectional study in a general hospital. Materials and Methods: Consecutive 149 suicide attempters were evaluated for psychosocial, situational, and clinical risk factors using the Risk Rescue Rating scale, Suicide Prevention Center scale, Lethality of Suicide Rating scale, and Presumptive Stressful Life Event scale. They were compared with healthy and psychiatric controls who had never attempted suicide. Statistical analysis: Chi-square for comparison of categorical variables, t-tests for comparison of means. Results: The male-to-female ratio was closer to one in adults and around 1:3 in adolescents. Younger age, lower-middle economic group, rural background, unemployed, school educated were more represented in this study. Compared to the controls, significantly more number of attempters had a family history of psychiatric illness and suicide, childhood trauma, medical consultation within one month, had experienced stressful life events and had expressed suicidal ideas. In a considerable proportion of attempts, risk was high and rescuability least; 59.1% had more than 50% chance of death. Suicide potential was high in almost half the cases. More than 80% of all attempters had psychiatric disorder; however, only 31.5% had had treatment. Factors like middle age, family history of psychiatric disorders, past psychiatric history, current psychiatric illness, communication of suicidal ideas, the use of physical methods, and high potential attempts, differentiated repeaters significantly from the first-timers. Major physical illness, family and marital conflicts, financial problems, and failure in examinations were more frequent life events. Childhood trauma, noted in around 40% of the

    Depression and cognitive impairment are frequent manifestations in Parkinson's disease (PD). Although a few longitudinal studies have reported on depression and dementia in PD, there is a yet a lack of such studies in India. This 7-year longitudinal study is a hospital-based prospective case (n = 250)-control (n = 280) study. In all, 36.8% had PD with no cognitive impairment (PD-Normal), 27.2% of the patients with PD were affected by dementia (PDD), and 36% of the remaining patients with PD had mild cognitive impairment (PD-MCI) at baseline. After 7 years of evaluation, 32 new patients, 12 patients from the PD-MCI group and 9 patients from the PD-Normal group, were diagnosed with dementia. The 7-year prevalence rate for dementia was estimated to be 49.28%. In the Indian population, an early onset of dementia is noted among patients with PD, with the age of onset being less than 55 years. Patients with early-onset PDD showed depression symptoms that differed significantly from the controls of the same age-group. There was a major difference in verbal fluency, word list recall, constructional praxis and recall, word list recognition, abridged Boston Naming Test, word list memory with repetition, and Mini-Mental State Examination between PD-MCI and PDD groups. Hallucinations before baseline (odds ratio [OR] = 4.427, 95% confidence interval [CI] = 2.122-9.373), akinetic/tremor dominancy (OR = 0.380, 95%CI = 0.149-0.953), and asymmetrical disease onset (OR = 0.3285, 95%CI = 0.1576-0.685) can be considered as risk factors for patients with dementia. Patients with early-onset PD might be more prone to complex depression and dementia. As the disease progresses, akinetic-dominant PD, early hallucinations, and asymmetrical disease onset are the potential risk factors for the development of dementia in patients with PD.

    Acute poisoning in children is a problem ubiquitous in distribution and is an important paediatric emergency. The present research was aimed to study the pattern and outcome of childhood poisoning under the age of 15 years at a tertiary care centre in South India to characterize the problem of acute paediatric poisoning among the children in different age group in the region. Medical records of all poisoning patients admitted during 2010 and 2011 were reviewed, and the information relating to the sociodemographic and clinical profile of the patients was recorded. Acute poisoning was reported in 81 children aged below 15 years during the study period. 50.6% were boys (n = 41) and 49.4% girls (n = 40). The mean age of the study sample was 6.8 years. Mean age was observed to be higher in females than males. The maximum number of cases were observed in the below 5 years age group (n = 45). A male predominance was evident in the below 5 years age group, while a female predominance in the age group between 10 and 15 years. Kerosene (n = 23, 28.4%) and organophosphate compounds (n = 16, 19.8%) were the most common agents responsible for poisoning in children. The majority of the poisoning cases were reported to the hospital within 12 h of the incident (n = 65, 83.3%). The mortality in paediatric poisoning was observed to be 7.4%. The majority of the children (n = 68, 84.0%) recovered, while seven patients had left the hospital against medical advice (8.6%). The study reports agrochemicals and hydrocarbons to be the most commonly implicated agents in paediatric poisoning. The cause of paediatric poisonings varies in different age groups and hence, preventive strategies should be planned accordingly. PMID:24931857

    The burden of social inequality falls disproportionately on child health and survival. This inequality raises the question of how wide this gap is, or what its relation is with the level of child mortality. Whether these disparities are increasing or declining with the development and how they differ from region to region or from state to state within the country needs to be looked into. As a measure of inequality and to compare the disparities between different states of India, concentration curves and indices are constructed from infant and under five mortality data classified under different quintiles of wealth index from the National Family Health Survey (NFHS-3) data of India. Inequality measures indicate that inequality in child mortality is more concentrated in the comparatively developed states than the poorer states in India. PMID:23435164

    Background Hypertension (HTN) is one of the major causes of cardiovascular morbidity and mortality. The objective of the study was to investigate the burden and predictors of HTN in India. Methods 6120 subjects participated in the Screening and Early Evaluation of Kidney disease (SEEK), a community-based screening program in 53 camps in 13 representative geographic locations in India. Of these, 5929 had recorded blood pressure (BP) measurements. Potential predictors of HTN were collected using a structured questionnaire for SEEK study. Results HTN was observed in 43.5% of our cohort. After adjusting for center variation (p < 0.0001), predictors of a higher prevalence of HTN were older age ≥40 years (p < 0.0001), BMI of ≥ 23 Kg/M2 (p < 0.0004), larger waist circumference (p < 0.0001), working in sedentary occupation (p < 0.0001), having diabetes mellitus (p < 0.0001), having proteinuria (p < 0.0016), and increased serum creatinine (p < 0.0001). High school/some college education (p = 0.0016), versus less than 9th grade education, was related with lower prevalence of HTN. Of note, proteinuria and CKD were observed in 19% and 23.5% of HTN subjects. About half (54%) of the hypertensive subjects were aware of their hypertension status. Conclusions HTN was common in this cohort from India. Older age, BMI ≥ 23 Kg/M2, waist circumference, sedentary occupation, education less, diabetes mellitus, presence of proteinuria, and raised serum creatinine were significant predictors of hypertension. Our data suggest that HTN is a major public health problem in India with low awareness, and requires aggressive community-based screening and education to improve health. PMID:24602391

  17. A qualitative study of factors affecting mental health amongst low-income working mothers in Bangalore, India

    Background Low-income urban working mothers face many challenges in their domestic, environmental, and working conditions that may affect their mental health. In India, a high prevalence of mental health disorders has been recorded in young women, but there has been little research to examine the factors that affect their mental health at home and work. Methods Through a primarily qualitative approach, we studied the relationship between work, caring for family, spousal support, stress relief strategies and mental health amongst forty eight low-income working mothers residing in urban slums across Bangalore, India. Participants were construction workers, domestic workers, factory workers and fruit and vegetable street vendors. Qualitative data analysis themes included state of mental health, factors that affected mental health positively or negatively, manifestations and consequences of stress and depression, and stress mitigators. Results Even in our small sample of women, we found evidence of extreme depression, including suicidal ideation and attempted suicide. Women who have an alcoholic and/or abusive husband, experience intimate partner violence, are raising children with special needs, and lack adequate support for child care appear to be more susceptible to severe and prolonged periods of depression and suicide attempts. Factors that pointed towards reduced anxiety and depression were social support from family, friends and colleagues and fulfilment from work. Conclusion This qualitative study raises concerns that low-income working mothers in urban areas in India are at high risk for depression, and identifies common factors that create and mitigate stress in this population group. We discuss implications of the findings for supporting the mental health of urban working women in the Indian context. The development of the national mental health policy in India and its subsequent implementation should draw on existing research documenting factors associated

    The escalation of Assisted Reproductive Technologies (ARTs) in India into a veritable fertility industry is the result of a multitude of reasons. This paper places the bio-genetic industry within the larger political economy framework of globalisation and privatisation, thus employing a framework that is often omitted from discussions on ARTs, but has direct and significant bearings on the ART industry in India. As markets for human organs, tissues and reproductive body parts experience unprecedented growth, the limits of what can or should be bought and sold continue to be pushed. As such, bodies have emerged as sale-worthy economic capital. Commercial flows of reproductive
