    Full Text Available Background: Tamil Nadu is one of the 18 states affected by fluorosis in India. The maximum tolerance limit of fluoride in drinking water specified by the World Health Organization (WHO, 1984 is 1.5 mg/l while it is proved to be above in many areas of Salem. Aims and Objectives: The aim of the following study is to identify the prevalence of dental fluorosis among children in the district of Salem. To compare the prevalence of dental fluorosis between different sexes and age groups. Materials and Methods: A pilot study was conducted in a private school where oral examination was done using mouth mirror and probe under sunlight in 965 students, for the presence or absence of dental fluorosis. As it was a pilot study, the fluorosis indexes were not taken into consideration. Results: In our study, 965 students were examined for dental fluorosis out of which, 624 were boys and 341 were girls. Dental fluorosis was present in 31.1% of boys, and 30.3% of girls 297 students out of 965 (30.8% showed the presence of dental fluorosis. Conclusion: The present study showed that Salem is one of the districts affected by dental fluorosis in Tamil Nadu. An extensive study including the grades of fluorosis and estimation of water fluoride levels in different areas is required for better evaluation of the situation. Government should take actions to prevent fluorosis. Awareness should be given to the population to drink only the water supplied by the government.

    This paper uses empirical material from health activists in Tamil Nadu to show that the health discourses that enjoy the greatest continuity and reach in India are also those that presume a radical connection between the health of the individual body and mobilising for a more just social order. The forging of this tradition is traced back to early anti-colonial forms of mobilisation. The transmission of this tradition is then ethnographically traced through various organisations that relay a characteristic set of orientations of thought and action to new generations and groups. The freshness of the synthesis of the tradition effected by each activist is emphasised. Arguing along phenomenological lines, these capacities to synthesise and renew a tradition are located in the capacities of the body. By attending to the unique place of the body in human experience, we may be in a better position to also understand the way in which health discourses that are embedded within wider experiences of injustice are able to circulate with renewed affective force.

    Carbonatites of Tamil Nadu (Samalpatti, Sevattur, Hogenakkal and Pakkanadu-Mulakkadu area), tectonically emplaced along faults/fractures of Neoproterozoic Koratti Fault Zone are predominantly calcio-carbonatite to ferro-carbonatite. Their magmatic origin is indicated by intrusive nature, association with alkaline-peralkaline complexes, degree and extent of fenitization and presence of diagnostic accessory mineral phases. The stable isotopic ratios (δ 13 C and δ 18 O) reported in the present work provide conclusive evidence of their magmatic origin. Enrichment of 18 O in some of the ferrocarbonatites appears to be a post-magmatic phenomenon and can be attributed to low temperature hydrothermal alteration. (author)

    Full Text Available An attempt was made to identify the extent of pollution in the aquifer matrix of Tirupur, a highly industrialized zone of Tamilnadu state, South India. Electrical imaging techniques were adopted with a Syscal Pro-96 system, for measuring apparent resistivity values using different electrodes separation. The first profile conducted atValipalayam recorded a resistivity range of <10 Ùmat a depth of 8m, which indicates contamination of top soil due to discharge of effluents. An increase in resistivity >45.5 Ùmwas observed at a depth of 27 to 47 mindicating the possibility of contamination. The second profile conducted at Pethichettipuram indicates source of contaminationat left end corner with a drop in resistivity <46.5 Ù m at a depth of 7.91 m. A drop in resistivity <21.6 Ù m was also observed at a depth of 11.5 m indicating a contaminated zone in deeper regolith. The thirdsurvey conducted in Palayakadu indicates contamination of regolith at a depth of 0 to 20 mwith a resistivity less than 40 Ùm. The fourth survey at Chellapuram indicates contamination of overburden with resistivity >11.5 Ùm, to a depth of about 10 m. Five imaging surveys conducted across the contaminated sites reveals that shallower regoliths are highly contaminated and deeper aquifers are free from contamination except a few locations.

    South India is characterized by a wide variety of landscapes, soils and climatic zones. It is comprised of tropical, semi-arid, humid-moist, and high-altitude environments, which support a diversity of agricultural systems. Our study focused on the state of Tamil Nadu, which is characterized by a generally tropical climate, and receive rainfall during both the southwest monsoon season (SWM, June to September) and the northeast monsoon (NEM, September to December). Agriculture continues to be an important sector in the state economy, as more than 56 of the people depend on agriculture and allied sectors for their livelihood. Analysis of land-use patterns in Tamil Nadu reveals that in the past decade there has been a reduction in net sown area and current fallow, while the share of cultivable wastelands has increased. The area under cereals, pulses, and oilseeds had marginally declined, although area under commercial crops like turmeric, sugar-cane, banana, fruits, and vegetables has shown an increasing trend. The production performance of major crops like cereals, pulses, and oilseeds has not shown any significant increase. Demand and supply gap of important crops in Tamil Nadu for the year 2010 indicates that the state is lagging far behind in the production of various crops.

    We analysed the genetic structure of ≈ 1000 samples representing 27 ethnic groups settled in Tamil Nadu, south India, derived from two linguistic families (Dravidians and Indo-Europeans) representing four religious groups (Hinduism, Islam, Christianity and Jainism) using 11 mtDNA markers. Out of 27 ethnic groups, four are in situ populations (Anglo-Indian, Labbai Muslim, Nadar Christian and south Indian Jain) and two are migrants (Gypsy and north Indian Jain) from north India to Tamil Nadu, and 21 are native ethnic groups. Six of the markers we used were monomorphic (HaeIII663, HpaI3592, AluI5176, AluI7025, AluI13262, 9-bp deletion) and five markers were polymorphic (DdeI10394, AluI10397, HinfI12308, HincII13259 and HaeIII16517). Haplogroup frequencies, genetic affinities and admixture analysis are based on the genotype data of polymorphic markers observed in these populations. Haplogroup frequencies indicate that various ethnic groups entered Tamil Nadu during different time periods. Genetic affinities and admixture estimates revealed that the ethnic groups possessing advanced knowledge of farming cluster in a branch (C), and could be the late arrived settlers as agriculture, was introduced to this region at about 5 to 3 thousand years ago. In situ ethnic groups appear to have arisen at various times as a result of the prevailing dominant socio-cultural forces. Hierarchical Hindu caste system created many ethnic groups in the history of its existence; some of them became isolated for considerable period of time. Over all, among Tamil ethnic groups, in spite of caste systems' rigidity, built in flexibility in the system in the form of hypergamy and hypogamy had allowed maternal gene flow between them.

    Full Text Available Objective: To obtain information on caries prevalence and treatment needs of children aged 5-10 years to plan appropriate dental care services in rural areas. Materials and Methods: Children studying in all the primary schools (six schools in the field practice area of the Rural Health Centre of the Faculty of Medicine, Annamalai University, Chidambaram, were surveyed. Each child was clinically examined in the schools by calibrated examiners. Dental caries was assessed using diagnostic criteria recommended by WHO (1997. The chi-square test and two-way analysis of variance were used for statistical analysis. Results: Five hundred and eight 5-10 year-old school children (247 boys and 261 girls were surveyed. Caries prevalence was 71.7 and 26.5% in primary and permanent dentition, respectively. The mean dmft and decayed missing filled tooth (DMFT scores were 3.00 and 0.42 respectively. The mean dmft decreased with age ( P < 0.01 whereas the mean DMFT increased with age ( P < 0.001. Although the mean dmft scores were not statistically significant different for the two sexes, the mean DMFT score was found to be higher among girls than among boys ( P < 0.02. The entire dmft/DMFT value represented the ′decay′ component only. There was a strong need for single surface restorations (60.6%. In the WHO index age (5-6 years, the caries prevalence was 70.2% (29.8% caries-free with a mean dmft value of 3.54 ± 3.71. Conclusion: Dental caries is a significant public health problem in this population. An extensive system to provide primary oral health care has to be developed in the rural areas of India.

    Information on disability is essential for the government to formulate policies, allocate adequate resources and implement appropriate programmes. We aimed to estimate the prevalence of disability and describe the types of disability by gender, age and geographical regions in Tamil Nadu, India. We analysed the 2011 Census cross-sectional survey data of Tamil Nadu. Age-adjusted disability rates and disability rates per 100 000 population were calculated. There were 1 179 963 disabled individuals in Tamil Nadu in 2011, a disability rate of 1635 per 100 000 population. Disability in movement, hearing and sight individually accounted for 24%, 19% and 11% of the total disability, respectively. Sixteen districts had disability rates above the state average. As age advanced, disability rates increased; the highest disability rate of 2533 per 100 000 was among people aged 60 years and above. The disability rates were higher in males compared to females (1819 v. 1451 per 100 000). Rural areas had higher disability areas compared to urban (1670 v. 1599 per 100 000). Currently married, working populations and literate populations had lower disability rates. Disability rate in the Scheduled Castes was higher at 1763 per 100 000 compared to the Scheduled Tribes and other social groups. Multiple disability was high in the age groups 0-19 years and 60 years and above. Physical or mental disability was observed in 1.6% of the population of Tamil Nadu. Research is warranted to identify underlying causes and interventions to reduce the burden of disability in the state.

    Context: Non-communicable diseases, no longer a disease of the rich, impose a great threat in the developing nations due to demographic and epidemiological transition. This increasing burden of non-communicable diseases and their risk factors is worrisome. Adherence to hypertension (HT) medication is very important for improving the quality of life and preventing complications of HT. Aim: To study the factors determining adherence to HT medication. Settings and Design: A community-based cross-sectional study was conducted in a rural area of Kancheepuram district, Tamil Nadu, with a total population of around 16,005. Materials and Methods: This study was carried out over a period of 6 months (February-July) using a pre-structured and validated questionnaire. All eligible participants were selected by house-to-house survey and individuals not available on three consecutive visits were excluded from the study. The questionnaire included information on demographic characteristics, lifestyle habits, adherence to HT medication, blood pressure, and body mass index (BMI). Caste was classified based on Tamil Nadu Public Service commission. Statistical Analysis: Data were entered in MS Excel and analyzed in SPSS version 16. P value <0.05 was considered statistically significant. Ethical Consideration: Informed verbal consent was obtained prior to data collection. The patient's adherence to HT medication was assessed using the Morisky 4-Item Self-Report Measure of Medication-taking Behavior [MMAS-4]. Results: We studied 473 hypertensive patients of which 226 were males and 247 were females. The prevalence of adherence was 24.1% (n = 114) in the study population. Respondents with regular physical activity, non-smokers and non-alcoholics were more adherent to HT medication as compared with respondents with sedentary lifestyle, smoking and alcohol intake (P < 0.005). Based on health belief model, the respondents who perceived high susceptibility, severity, benefit had better

    Global contraceptive usage was 63.3 % in 2010 which was 9 % more than that in 1990. NFHS-III 2005-2006 revealed that the contraceptive prevalence rate was 56 % while in the past decade it was 48 %. In India, female sterilization is the most commonly preferred method of contraception accounting for 76 %, while in Tamil Nadu it was 90 %. Thus, this study aims at measuring the prevalence of unmet needs of family planning and its determinants in a rural area of Kancheepuram district, Tamil Nadu. The study was carried out as a community-based cross-sectional study in Chunambed panchayat, a rural area in Kanchipuram District, Tamil Nadu, India, among 505 women of age group 15-49 years. Cluster random sampling was done to select the households to include in the study. In every household, all the available and eligible women were explained about the study and recruited after obtaining informed consent. Chi-square test was applied for finding the difference in proportion, and p value family planning in our study population was nearly 31 %; it was even more for younger age groups and for the women whose family size was less. 51.7 % of the participants were currently using a contraceptive measure and very few of their partners used contraception. Government health facilities were the major source of contraceptive service and majority of our participants were well aware about the various contraceptive methods. Unmet needs of family planning were high in our study population, and the knowledge about the contraceptive use and family planning was found to be fairly adequate.

    Traditional medicine remained as the most affordable and easily accessible source of treatment for many ailments. The Malayali tribes living in the Kolli hills region of Eastern Ghats of Tamil Nadu has long history of ethnomedicinal knowledge has been remained unexplored hither to. Hence, this study was initiated with an aim to record the ethnomedicinal plants of Malayali tribes and to document and analyse the local knowledge on phytotherapy before environmental and cultural changes deplete the resources. In order to document the phytotherapical knowledge, a field study was carried out between August 2012 and February 2014. The ethnomedicinal knowledge was recorded through interviews among the Malayali tribes, and traditional healers. In addition a semi structure questionnaire was used to collect information on the local name of the plant, plant part used for curing, method of preparation in phytoremedies and any other plants/agents used as ingredients. Factor of informant consensus (Fic), use value (UV), fidelity level (FL), relative importance (RI) and novelty index were employed in data analysis. Current research work reports total of 86 medicinal plant species belonging to 76 genera of 46 different families. Herbs constituted the largest growth habit (48 species, 56%) followed by trees (13 species, 15%) and shrubs (9 species, 11%) etc. Leaf 43 (46%) is the plant part widely used followed by whole plant 9 (10%), seeds and fruits 9 (10%) and root 7 (8%). Paste was the most common preparation method use in herbal recipes. These plants were used to treat various human diseases and ailments grouped under 19 disease categories with the highest number of species (31) being used for dermatological infections/diseases followed by gastro-intestinal ailments (28) and general health (15). Asystasia chelonoides (UV of 2.76) and Piper nigrum (UV of 2.12) are the most frequently and popularly used medicinal plant species in the study area. The result of the study revealed

    The feasibility of a potential bioindicator based on functional groups of microzooplankton tintinnids for bioassessments of water quality status was studied during southwest monsoon (June to September) along the coastal waters of Kalpakkam, India during 2012-2015. The work highlights the following features (1) tintinnid community composed of 28 species belonging to 11 genera and 9 families, revealed significant differences among the four study sites (2) maximum numerical abundance (2224±90ind. l -1 ) and species diversity (H'=2.66) of tintinnid were recorded towards Bay of Bengal whereas minimum abundance (720±35ind. l -1 ) and diversity (H'=1.74) were encountered in the backwater sites, (3) multivariate analyses [RELATE, Biota-environment (BIOENV) and canonical analysis of principal coordinates (CAP)] reveal that chl a, nitrate and phosphate were the potential causative factors for tintinnid distribution. Based on the results, we suggest that tintinnids may be used as a potential bioindicator of water quality status in marine ecosystem. Copyright © 2016 Elsevier Ltd. All rights reserved.

    In situ radiometric survey carried out in 81 revenue villages of Kanyakumari District, Tamil Nadu, India, using a portable radiation dosemeter/detector, revealed the existence of radiation hotspots along the coastal belt. A close observation of the coastal villages specifically revealed high background radioactivity in 14 coastal villages. A very high intrinsic anomalous radioactivity of 41.03 μSv h(-1) was observed, in a famous tourist spot in the coastal belt of Kanyakumari District. This is the highest level of radiation registered in South India, which is extremely higher than the permissible world average and is suggestive of causing severe clinical problems on continuous and prolonged exposure.

    Mangrove and halophytic plants occur along the coastal areas of Tamil Nadu, south India and these plants have been used in traditional medicine for centuries. Heavy metals are known to pose a potential threat to terrestrial and aquatic biota. However, little is known on the toxic levels of heavy metals found in mangrove and halophytic plants that are used in traditional medicine in India. To understand heavy metal toxicity, we investigated the bioconcentration factors (BCF) of heavy metals in leaves collected from eight mangroves and five halophytes in the protected Pichavaram mangrove forest reserve in Tamil Nadu State, south India. Data presented in this paper describe the impact of essential (Cu, Fe, Mg, Mn and Zn) and non-essential/environmentally toxic trace metals (Hg, Pb and Sn) in mangrove and halophytic medicinal plants. The concentrations of Pb among 13 plant species were higher than the normal range of contamination reported for plants. The average concentration of Hg in the halophytic plants (0.43 {+-} 0.37 {mu}g/g) was seven times higher than mangrove plants (0.06 {+-} 0.03 {mu}g/g) and it indicated pollutants from industrial sources affecting halophytes more than mangroves. - Metal effects occur in India's mangrove ecosystem.

    To isolate novel actinomycetes and to evaluate their antibacterial activity. Three soil samples were collected from Vengodu (village) in Kanchipuram district, Tamil Nadu, India. Actinomycetes were isolated using serial dilution and plating method on actinomycetes isolation agar. Totally 35 isolates were obtained on the basis of colony characteristics on actinomycetes isolation agar. All the isolates were screened for antibacterial activity by cross streak method. Medium and optimization of day were done for the potent strains using Nathan's agar well diffusion method. Isolation of bioactive compounds from significant active isolates was done by using different media. The most active isolate VAS 10 was identified as Actinobacterium Loyola PBT VAS 10 (accession No. JF501398) using 16s rRNA sequence method. The hexane, ethyl acetate, dichloromethane and butanol extracts of VAS 10 were tested against bacteria. The maximum antibacterial activity was observed in dichloromethane and ethyl acetate; maximum zones of inhibition were observed against Enterococcus durans. The rRNA secondary structure and the restriction sites of Actinobacterium Loyola VAS 10 were predicted using Genebee and NEBCutter online tools respectively. The present study showed that among the isolated actinomycetes, Actinobacterium Loyola PBT VAS 10 (accession No. JF501398) showed good antibacterial activity against the tested bacteria.

    The primary deciduous forests in the Eastern Ghats (EG) of Tamil Nadu (TN) India have undergone many changes owing to various need-based forest managements, such as timber extraction for industry, railway sleepers, charcoal, and forest clearance for hydroelectric projects and agriculture, during preindependence and postindependence periods (i.e., from 1800 to 1980). The enactment of a forest conservation act during the 1980s changed the perception of forest managers from utilization to conservation. This study was taken up to assess the forests dynamics in the EG of TN spatially between 1990 and 2003 and nonspatially between 1900 and the 1980s. Landsat Thematic Mapper (TM) and Indian Remote Sensing satellite (IRS) 1D Linear Imaging and Self Scanning (LISS III) data were used to assess forests during 1990 and 2003, respectively. Field floristic survey and secondary data (such as published literature, floras, books, and forest working plans) were used to assess the forest dynamics in terms of forest type and species composition among the preindependence period, the postindependence period, and the present (i.e., before and after 1980). The satellite data analysis revealed a considerable amount of changes in all forest types during the 13 years. The comparison of species composition and forest types between the past and present revealed that need-based forest management along with anthropogenic activity have altered the primary deciduous forest in to secondary and postextraction secondary forests such as southern thorn and southern thorn scrub forests in the middle [400-900 m above mean sea level (MSL)] and lower slopes (900 m MSL) and plateau seemed not to be much affected by the forest management. The changes estimated by the satellite data processing in the major forest types such as evergreen, deciduous, southern thorn, and southern thorn scrub are really alarming because these changes have occurred after the implementation of a forest conservation act.

    Sakthivel Vaiyapuri

    Full Text Available BACKGROUND: Snakebite represents a significant health issue worldwide, affecting several million people each year with as many as 95,000 deaths. India is considered to be the country most affected, but much remains unknown about snakebite incidence in this country, its socio-economic impact and how snakebite management could be improved. METHODS/PRINCIPAL FINDINGS: We conducted a study within rural villages in Tamil Nadu, India, which combines a household survey (28,494 people of snakebite incidence with a more detailed survey of victims in order to understand the health and socio-economic effects of the bite, the treatments obtained and their views about future improvements. Our survey suggests that snakebite incidence is higher than previously reported. 3.9% of those surveyed had suffered from snakebite and the number of deaths corresponds to 0.45% of the population. The socio-economic impact of this is very considerable in terms of the treatment costs and the long-term effects on the health and ability of survivors to work. To reduce this, the victims recommended improvements to the accessibility and affordability of antivenom treatment. CONCLUSIONS: Snakebite has a considerable and disproportionate impact on rural populations, particularly in South Asia. This study provides an incentive for researchers and the public to work together to reduce the incidence and improve the outcomes for snake bite victims and their families.

    Full text: Radioactive minerals such as uranium ( 238 U), thorium ( 232 Th) and potassium ( 40 K) are considered to be Primordial radionuclides which are widely distributed in the earth's crust. Gamma-radiation from these radionuclides represents the main external source of irradiation for the human body. Human beings are exposed outdoors to the natural terrestrial radiation that originates predominantly from the upper 30 cm of the soil. A pilot project was therefore initiated aiming at systematically measuring the terrestrial gamma radiation in Tiruchirappalli city, Tamil Nadu, South India and to establish baseline data on the terrestrial background radiation level determining its contribution to the annual effective dose equivalent to the human population. The natural radioactivity concentrations were studied in soil samples collected from 50 locations in Tiruchirappalli city. The concentration varies significantly over different soil types and the highest radioactivity was measured over soil types of granite origin followed by red soil and alluvial loam. The mean activity concentrations of 232 Th, 238 U and 40 K in soil samples are found to be 81.78 Bq.kg -1 , 32.62 Bq.kg -1 , and 551.35 Bq.kg -1 respectively. The calculated gamma dose from the soil is in the range between 38.86nGy.h -1 and 240.59 nGy.h -1 with a mean value of 89.76 nGy.h -1 . The mean annual effective dose to the population from outdoor terrestrial gamma radiation was estimated to be 0.11mSv.y -1 which is low as compared with the maximum permissible effective dose equivalent of 1mSv.y -1 (ICRP,1991). In the present study it is observed that the major sources of gamma radiation in soils are mainly derived from rocky area with granite basement. (author)

    To investigate the poorly understood relationship between the process of urbanization and noncommunicable diseases (NCDs) through the application of a quantitative measure of urbanicity. We constructed a measure of the urban environment for seven areas using a seven-item scale based on data from the Census of India 2001 to develop an "urbanicity" scale. The scale was used in conjunction with data collected from 3705 participants in the World Health Organization's 2003 STEPwise risk factor surveillance survey in Tamil Nadu, India, to analyse the relationship between the urban environment and major NCD risk factors. Linear and logistic regression models were constructed examining the relationship between urbanicity and chronic disease risk. Among men, urbanicity was positively associated with smoking (odds ratio: 3.54; 95% confidence interval, CI: 2.4-5.1), body mass index (OR: 7.32; 95% CI: 4.0-13.6), blood pressure (OR: 1.92; 95% CI: 1.4-2.7) and low physical activity (OR: 3.26; 95% CI: 2.5-4.3). Among women, urbanicity was positively associated with low physical activity (OR: 4.13; 95% CI: 3.0-5.7) and high body mass index (OR: 6.48; 95% CI: 4.6-9.2). In both sexes urbanicity was positively associated with the mean number of servings of fruit and vegetables consumed per day (P Urbanicity is associated with the prevalence of several NCD risk factors in Tamil Nadu, India.

    Researchers, policy makers and civil society organizations have been discussing the potential of biofuels as partial substitutes for fossil fuels and thereby as a simultaneous solution for climate change and rural poverty. Research has highlighted the ambiguity of these claims across various dimensions and scales, focusing on ethanol-producing or oilseed crops in agricultural lands or Jatropha-type crops on common lands. We studied the agronomic and economic viability and livelihood impacts of Jatropha curcas plantations on private farms in Tamil Nadu, India. We found that Jatropha yields are much lower than expected and its cultivation is currently unviable, and even its potential viability is strongly determined by water access. On the whole, the crop impoverishes farmers, particularly the poorer and socially backward farmers. Jatropha cultivation therefore not only fails to alleviate poverty, but its aggressive and misguided promotion will generate conflict between the state and the farmers, between different socio-economic classes and even within households. The water demands of the crop can potentially exacerbate the conflicts and competition over water access in Tamil Nadu villages. (author)

    Groundwater quality assessment study was carried out around Manimuktha river basin, Tamil Nadu, India. Twenty six bore well samples were analyzed for geochemical variations and quality of groundwater. Four major hydrochemical facies (Ca-HCO(3), Na-Cl, Mixed CaNaHCO(3), and mixed CaMgCl) were identified using a Piper trilinear diagram. Comparison of geochemical results with World Health Organization, United States Environmental Protection Agency, and Indian Standard Institution drinking water standards shows that all groundwater samples except few are suitable for drinking and irrigation purposes. The major groundwater pollutions are nitrate and phosphate ions due to sewage effluents and fertilizer applications. The study reveals that the groundwater quality changed due to anthropogenic and natural influence such as agricultural, natural weathering process.

    In this paper, an energy planning optimisation procedure of a selected territory is illustrated and applied using an energy flow optimisation model. The developed approach takes into account various electricity generating options to meet the energy needs of various demand sectors. Energy saving techniques and hybrid technologies are considered and various scenarios are developed by assessing the contribution of renewable energy technologies over the planning period. The procedure aims to reduce the total actualised cost of energy generation over selected time horizon and predicts the additional installations required along with the existing facilities to meet the energy demand. At the same time the role of renewable energy technologies and of energy saving measures is evaluated by imposing suitable constraints on CO 2 emissions and primary energy sources exploitation. The procedure is applied to the territory of Tamil Nadu state (India) by considering different energy planning scenarios

    Full Text Available Objective: To evaluate the presence of heavy metal cadmium in six species of shellfish at Pulicat Lake, Tamil Nadu, India. Methods: Six species of shellfish, Fenneropenaeus indicus, Fenneropenaeus monodon, Fenneropenaeus semisulcatus, Scylla serrata, Clibanarius longitarsus and Meretrix casta (M. casta in Pulicat lake, Tamil Nadu, India were analysed for the presence of cadmium in the gills and muscles from January 2011 to December 2012. Results: The results showed seasonal variations in the uptake of cadmium. Very high accumulation of cadmium was found in the gills and muscles of M. casta during post monsoon, summer, premonsoon and monsoon. The corresponding values of cadmium present in the gills of M. casta were 1.59, 1.56, 1.48 and 1.46 µg/g in 2011 and 1.16, 1.25, 1.15 and 1.14 µg/g in 2012. Whereas for muscles, they were 1.14, 0.11, 0.96 and 0.80 µg/g in 2011 and 0.49, 0.34, 1.05 and 1.20 µg/g in 2012. Conclusion: The results of the present study has shown that the accumulation of cadmium found in the gills and muscles were high in M. casta when compared to other species of shellfish. Thus, the consumption of the shellfish is safe, but does not exclude bioaccumulation risk in their meat. This present study has highlighted the need for estuarine biomonitoring to avoid possible contamination of shellfish and its consumers. The overall scenario of the shellfish accumulating high levels of cadmium indicates that the Pulicat lake is polluted with undesirable elements and the risk of consuming the meat of shellfish by man and other carnivores may lead to their toxicity. Stringent control measures are necessary to control the pollution of this precious lake to reduce the bioaccumulation of toxic metals in organisms.

    India's dependence on a climate sensitive sector like agriculture makes it highly vulnerable to its impacts. However, agriculture is highly heterogeneous across the country owing to regional disparities in exposure, sensitivity, and adaptive capacity. It is essential to know and quantify the possible impacts of changes in climate on crop yield for successful agricultural management and planning at a local scale. The Hadley Centre Global Environment Model version 2-Earth System (HadGEM-ES) was employed to generate regional climate projections for the study area using the Regional Climate Model (RCM) RegCM4.4. The dynamics in potential impacts at the sub-district level were evaluated using the Representative Concentration Pathway 4.5 (RCPs). The aim of this study was to simulate the crop yield under a plausible change in climate for the coastal areas of South India through the end of this century. The crop simulation model, the Decision Support System for Agrotechnology Transfer (DSSAT) 4.5, was used to understand the plausible impacts on the major crop yields of rice, groundnuts, and sugarcane under the RCP 4.5 trajectory. The findings reveal that under the RCP 4.5 scenario there will be decreases in the major C3 and C4 crop yields in the study area. This would affect not only the local food security, but the livelihood security as well. This necessitates timely planning to achieve sustainable crop productivity and livelihood security. On the other hand, this situation warrants appropriate adaptations and policy intervention at the sub-district level for achieving sustainable crop productivity in the future.

    Cardiovascular diseases are one of the leading causes of death in India. There is high prevalence of cardiovascular risk factors in urban Tamil Nadu. There are limited data on the prevalence of behavioral risk factors and overweight in rural Tamil Nadu. We estimated prevalence of behavioral risk factors, overweight and central obesity in a rural population in Tamil Nadu, India. We conducted a cross-sectional survey in 11 villages in Kancheepuram/Thiruvallur districts, Tamil Nadu. Study population included 10,500 subjects aged 25-64 years. We collected data on behavioral risk factors and anthropometric measurements. Body mass index (BMI) was categorized using the classification recommended for Asians. Central obesity was defined as waist circumference ≥90 cm for men and ≥80 cm for women. We computed proportions for all risk factors and used trend chi-square to examine trend. Among the 10,500 subjects, 4927 (47%) were males. Among males, 1852 (37.6%) were current smokers and 3073 (62.4%) were current alcohol users. Among females, 840 (15.1%) were smokeless tobacco users. BMI was ≥23.0 kg/m 2 for 1618 (32.8%) males and 2126 (38.2%) females. 867 (17.6%) males and 1323 (23.7%) females were centrally obese. Most commonly used edible oil was palm oil followed by sunflower oil and groundnut oil. We observed high prevalence of tobacco use, alcohol use and central obesity in the rural population in Tamil Nadu. There is need for health promotion programs to encourage adoption of healthy lifestyle and policy interventions to create enabling environment.

In addition, model sensitivity has also been evaluated with six Planetary Boundary Layer (PBL) and two Land Surface Model (LSM) schemes. Model forecast was carried out using nested domain and the impact of model horizontal grid resolutions were assessed at 9 km, 6 km and 3 km. Analysis of the synoptic features using National Center for Environmental Prediction Global Forecast System (NCEP-GFS) analysis data revealed strong upper-level divergence and high moisture content at lower level were favorable for the occurrence of heavy rainfall event over the northeast coast of Tamil Nadu. The study signified that forecasted rainfall was more sensitive to the microphysics and PBL schemes compared to the LSM schemes. The model provided better forecast of the heavy rainfall event using the logical combination of Goddard microphysics, YSU PBL and Noah LSM schemes, and it was mostly attributed to timely initiation and development of the convective system. The forecast with different horizontal resolutions using cumulus parameterization indicated that the rainfall prediction was not well represented at 9 km and 6 km. The forecast with 3 km horizontal resolution provided better prediction in terms of timely initiation and development of the event. The study highlights that forecast of heavy rainfall events using a high-resolution mesoscale model with suitable representations of physical parameterization schemes are useful for disaster management and planning to minimize the potential loss of life and property.

    Full Text Available Bacteriological analyses were carried out on Ananthanar channel water of Kanyakumari district, Tamil Nadu, India. The Ananthanar channel was selected in this study because this channel runs about nearly 28 km and supplies water for many villages for drinking and bathing purposes. Fecal and total coliform counts were performed using the standard membrane filtration technique and multiple tube technique. The results obtained were compared with reports of All India Institute of Medical Sciences Standards for Drinking and Recreational Water. Faecal coliform counts varied from 12 to 180 MPN/100 ml while Escherichia coli counts ranged from 6 to 161 MPN/100 ml for all the sampled sites. Among the total coliform Pseudomonas aeruginosa, Shewanella putrefaciens, Klebsiella pneumoniae, Citrobacter freundii and Proteus mirabilis are reported. The Faecal coliform and the E. coli counts exceeding acceptable limits are indicative of pollution from domestic wastes from several informal settlements located along the riverbank. Water uses in the area were determined and were found to be mainly domestic and recreational. The gross pollution of the river exposes the local people who depend on it for their primary water source to serious health risk.

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

    Water quality of Tiruvallur Taluk of Tiruvallur district, Tamil Nadu, India has been analysed to assess its suitability in relation to domestic and agricultural uses. Thirty water samples, including 8 surface water (S), 22 groundwater samples [15 shallow ground waters (SW) and 7 deep ground waters (DW)], were collected to assess the various physico-chemical parameters such as Temperature, pH, Electrical conductivity (EC), Total dissolved solids (TDS), cations (Ca, Mg, Na, K), anions (CO3, HCO3, Cl, SO4, NO3, PO4) and trace elements (Fe, Mn, Zn). Various irrigation water quality diagrams and parameters such as United states salinity laboratory (USSL), Wilcox, sodium absorption ratio (SAR), sodium percentage (Na %), Residual sodium carbonate (RSC), Residual Sodium Bicarbonate (RSBC) and Kelley's ratio revealed that most of the water samples are suitable for irrigation. Langelier Saturation Index (LSI) values suggest that the water is slightly corrosive and non-scale forming in nature. Gibbs plot suggests that the study area is dominated by evaporation and rock-water dominance process. Piper plot indicates the chemical composition of water, chiefly controlled by dissolution and mixing of irrigation return flow.

  16. Registration and monitoring of pregnant women in Tamil Nadu, India: a critique.

    Gaitonde, Rakhal

    2012-06-01

    In 2008 a pregnancy registration system was introduced in rural Tamil Nadu, India, which is now being scaled up. It will collect data on antenatal, delivery and post-partum care in pregnant women and infant health. This is seen as an important public health intervention, justified for its potential to ensure efficiency in provision and use of maternity services. However, from another perspective, it can be seen as a form of control over women, reducing the experience of safe pregnancy and delivery to a few measurable variables. The burden of implementing this task falls on Village Health Nurses, who are also women, reducing their time for interacting with and educating people and visiting communities, which is their primary task and the basis on which they are evaluated. In addition, they face logistical constraints in rural settings that may affect the quality of data. In a health system with rigid internal hierarchies and power differentials, this system may become more of a supervisory and monitoring tool than a tool for a learning health system. It may also lead to a victim-blaming approach ("you missed two antenatal visits") rather than health system learning to improve maternal and infant health. The paper concludes by recommending ways to use the system and the data to tackle the broader social determinants of health, with women, health workers and communities as partners in the process.

    This article highlights the efforts of the Community Health and Development (CHAD) Programme of Christian Medical College to address the issues of gender discrimination and improve the status of women in the Kaniyambadi Block, Vellore, Tamil Nadu, India. The many schemes that are specifically for women and general projects for the community from which women can also benefit represent a multi-pronged approach whose aim is the improvement of women's health, education and employment in the context of community development. However, despite five decades of work with a clear bias in favour of women, the improvement in health and the empowerment of women has lagged behind that achieved by men. We believe this is because the community, with its strong male bias, utilises the health facilities and education and employment programmes more for the benefit of men and boys than women and girls. The article argues for a change of approach, in which gender and women's issues are openly discussed and debated with the community. It would appear that nothing short of social change will bring about an improvement in the health of women and a semblance of gender equality in the region.

    Full Text Available Keeping in view the importance of efficiency in resource utilization in healthcare sector, we focus on efficiency of health care system at sub-state level (i.e., district level in India using Tamil Nadu state and its district level data for 2012-13. It being an economically advanced state, in terms of Infant Mortality Rate (IMR the state ranks second lowest among the Indian states. We explore the reasons for relative performance of different districts with Data Envelopment Analysis. We used IMR as output variables. Using Principal component analysis we tried a sub-set of variables which had low correlations. Thus three components with an Eigen value greater than one were used. These related to Total beds in ESI (Employees state Insurance scheme hospitals, Population per doctor of PHPM (Public Health and Preventive Medicine and Full Vaccination. The factor scores for these components were used for Data Envelopment Analysis (DEA. We have focused on CCR scores (or constant returns to scale technical efficiency, CRST score and efficiency rankings based on these are discussed. Thus our results pertaining to district level health system efficiency for Tamil Nadu state indicate that some of the districts have low efficiency in utilization of inputs like doctors and beds. There are also other districts which need more of these inputs which may enhance their output and efficiency. Thus it suggests that that the lowest performance of Kancheepuram district, for instance, is mainly owing to low availability of these health inputs as well as partly due to less efficient utilisation of inputs. It is also inferred that higher efficiency of Chennai is due to better availability of hospital beds and doctors per population. Among the factors external to health system, the statistical significance of an improved source of drinking water indicates that supportive input of better potable water supply helps to improve in general health status and thus reduce inter

    Full Text Available Livestock keepers comprise 2/3rds of the 2.8 billion households living on less than two dollars per day. However, as a group they tend to be marginalised and excluded from formal service provision, particularly in relation to animal health. Therefore, the following paper describes the development of the Livestock Guru, a multi-media learning programme created to meet the knowledge needs of poor livestock keepers in Tamil Nadu, India. The findings from the study illustrate the importance of both appropriate visuals, voice-overs but also the need for addressing issues in the environment in which learning will take place.

    Forty-two Bacillus sphaericus strains were isolated from soil around Tamil Nadu, India. The phylogenetic relationship among the B. sphaericus isolates was analysed by REP-PCR and multiplex PCR was performed for the detection of mosquito larvicidal genes binA, binB, mtx1, mtx2 and mtx3 in B. sphaericus isolates. According to the REP-PCR band pattern, B. sphaericus isolates were divided into group A comprising I-XI clusters and group B comprising cluster XII. Three of the isolates BSTN01, 23 and 24 were gathered under cluster XII showed a high level of larvicidal activity against Culex quinquefasciatus and Anopheles stephensi, the other 39 isolates grouped under I-XI clusters were non-toxic or weak or moderately toxic to mosquito larvae. Even though BSTN23 and 24 were isolated from the same location and both contained all the five mosquito larvicidal genes, their intraspecies difference was clearly elucidated by REP-PCR analysis. Among high toxic isolates, BSTN23 and 24 were observed to contain all the five toxin genes and BSTN01 showed the presence of binary toxin and Mtx1 toxin genes. The isolates BSTN02, 03, 07, 14, 16, 19, 20, 21, 25, 31, 36 and 39 were found to contain mtx1 gene with combination of mtx2 and/or mtx3 showed moderate or low toxicity against mosquito larvae. binA, binB and mtx1 genes were not present in non-toxic isolates. The present study revealed the genetic heterogeneity between both toxic and non-toxic isolates and indicates that there is a good correlation between the presence of toxin genes and toxicity of the strains. These techniques could be developed in screening of novel highly toxic B. sphaericus strains from environment without bioassay on mosquito larvae. Copyright © 2013 Elsevier B.V. All rights reserved.

  5. Why seawater intrusion has not yet occurred in the Kaluvelli-Pondicherry basin, Tamil Nadu, India

    2017-09-01

    Worldwide, coastal aquifers are threatened by seawater intrusion. The threat is greatest when aquifers are overexploited or when recharge is low due to a semi-arid or arid climate. The Kaluvelli-Pondicherry sedimentary basin in Tamil Nadu (India) presents both these characteristics. Groundwater levels in the Vanur aquifer can reach 50 m below sea level at less than 20 km inland. This groundwater depletion is due to an exponential increase in extraction for irrigation over 35 years. No seawater intrusion has yet been detected, but a sulphate-rich mineralization is observed, the result of upward vertical leakage from the underlying Ramanathapuram aquifer. To characterize the mechanisms involved, and to facilitate effective water management, hydrogeological numerical modelling of this multi-layered system has been conducted. Existing and acquired geological and hydrodynamic data have been applied to a quasi-3D hydrogeological model, NEWSAM. Recharge had been previously quantified through the inter-comparison of hydrological models, based on climatological and surface-flow field measurements. Sensitivity tests on parameters and boundary conditions associated with the sea were performed. The resulting water balances for each aquifer led to hypotheses of (1) an offshore fresh groundwater stock, and (2) a reversal and increase of the upward leakage from the Ramanathapuram aquifer, thus corroborating the hypothesis proposed to explain geochemical results of the previous study, and denying a seawater intrusion. Palaeo-climate review supports the existence of favourable hydro-climatological conditions to replenish an offshore groundwater stock of the Vanur aquifer in the past. The extent of this fresh groundwater stock was calculated using the Kooi and Groen method.

    Full Text Available Introduction: Neonatal sepsis is a leading cause of neonatal mortality and morbidity in the world. The objective of the current study was to detect the common causative microorganisms of neonatal sepsis and their antimicrobial resistance patterns in a rural secondary hospital in Tamil Nadu, India. Materials and Methods: Neonates (0–28 days admitted to this newborn care unit from October 2013 to September 2015, with a diagnosis of probable sepsis were studied. All the enrolled babies had blood cultures taken and were followed up till final outcome, which was discharge or death, irrespective of culture result. Univariate analysis was performed for factors associated with culture positivity, generating odds ratios, and confidence intervals. Results: Among the 107 babies with a diagnosis of probable sepsis, 28 (26.2% had shown bacteria in culture. The majority (94.4% were of early-onset sepsis. The predominant organisms were Staphylococcus aureus (10/28 and Klebsiella (6/28. 100% of Gram-negative bacilli and 90% of Staphylococcus were resistant to Ampicillin. Gentamicin resistance among Gram-negative bacilli and Staphylococcus was 52.9% and 20%, respectively, while third-generation cephalosporin resistance was 31.2% and 20%, respectively. Among the neonates diagnosed as probable sepsis, idiopathic prematurity (P = 0.007 was found to have a statistically significant association with culture-positive sepsis. Conclusion: The culture positivity rate among the neonates with probable sepsis in the current study was 26%. An alarmingly high degree of antibiotic resistance observed calls for robust infection control practices and an urgent evaluation and development of individual and national antibiotic policies for neonatal sepsis.

    This study examined the post-sterilization autonomy of women in south India in the context of early sterilization and low fertility. Quantitative data were taken from the third round of the National Family Health Survey (NFHS-3) carried out in 2005-06, and qualitative data from one village each in Kerala and Tamil Nadu during 2010-11. The incident rate ratios and thematic analysis showed that among currently married women under the age of 30 years, those who had been sterilized had significantly higher autonomy in household decision-making and freedom of mobility compared with women who had never used any modern family planning method. Early age at sterilization and low fertility enables women to achieve the social status that is generally attained at later stages in the life-cycle. Policies to capitalize on women's autonomy and free time resulting from early sterilization and low fertility should be adopted in south India.

    Snakebites cause death, disability and economic devastation to their victims, people who live almost exclusively in rural areas. Annually an estimated two million venomous bites cause as many as 100,000 deaths worldwide as well as hundreds of thousands of deformities and amputations. Recent studies suggest that India has the highest incidence of snakebite and associated deaths worldwide. In this study, we interviewed 25 hospital-based clinicians who regularly treat snakebites in Tamil Nadu, India, in order to gauge their opinions and views on the diagnostic tools and treatment methods available at that time, the difficulties encountered in treating snakebites and improvements to snakebite management protocols they deem necessary. Clinicians identified the improvement of community education, training of medical personnel, development of standard treatment protocols and improved medication as priorities for the immediate future.

    The aim of the present study was to document the knowledge of traditional Siddha medical practitioners from Radhapuram taluk of Tirunelveli district in Tamil Nadu, India, and to quantitatively analyze the data to identify some useful leads for further studies. Successive free listing was the method adopted for the interview. In this study, 84 traditional Siddha medical practitioners were included and their knowledge on medicinal plants was gathered. The data were assessed with the help of two indices viz., Informant Consensus Factor (F(ic)) and Informant Agreement on Remedies (IAR). The present survey is in accordance with some of the aspects of our previous surveys. Regarding the demography of the informants, it exhibited unevenness in male-female ratio and majority of the informants were poorly educated. Practicing this system of medicine as part time job by majority of the informants might indicate the reduced social status of this medicinal system. The present study had recorded the usage of 217 species which were used to prepare 448 formulations, which in turn yielded 812 use reports. Conversion of use reports had yielded a total of 625 claims and 84.16% of the claims were 'singletons'. The illness category 'adjuvants' holds a high F(ic) value. Among the other illness categories, kapha ailments and dermatological ailments have a high percentage of use-reports. Ailments of blood, jaundice and fever were the other illness categories with high F(ic) values. Some of the claims viz., Mukia madarasepatana (kapha ailments), Mollugo nudicaulis (febrifuge), Indigofera asphalathoides (dermatological ailments), Aerva lanata (urinary ailments), Abutilon indicum (hemorrhoids) and Hybanthus enneaspermus (aphrodisiac), which have relatively high consensus can be taken up for further biomedical studies, since no substantial studies have been conducted on them. One of the major aims of National Rural Health Mission is to implement traditional Indian system of medicines into

    Marriage in Indian society is a religious duty. Consanguineous marriage is common, where individuals prefer to marry within their clan (a unilateral kin group based on either matrilineal or patrilineal descent). Keeping in mind that this form of marriage has certain disadvantages for social and biological as well as demographic aspects of individuals and families, the present study examines the influence of mate selection (i.e., close relatives, distant relatives, not related) on female age at marriage, pregnancy wastages, and survival status of the first child. The study was designed based on the information collected on a sample size of 3,948 married women aged 13-49 in Tamil Nadu, India, by the National Family Health Survey (NFHS), 1992. Results suggest that 48 per cent of women in Tamil Nadu marry their relatives. This practice of marrying relatives is high in rural areas, among Hindus, Scheduled Castes/tribes, and illiterate women as compared to urban areas, among non-Hindus, non-SC/ST, and educated women, respectively. The bivariate analysis reveals that women marrying their close relatives had low age at marriage and experienced a higher per cent of pregnancy wastage and child loss (first child) as compared to those women marrying their distant relatives or nonrelatives. The result is found to be consistent even after controlling for selected background variables through multivariate techniques (applied separately for age at marriage, pregnancy wastages, and the survival status of first child). Hence, this study suggests that steps should be taken to inform people about the problems of marrying close relatives through appropriate IEC programs in Tamil Nadu.

    2009-11-01

    Full Text Available There is evidence that a specific type of allergic conjunctive-uveal granuloma reported from South India could be due to infection by a trematode parasite. In these patients, the histopathological examination of the eye reveals a zonal granulomatous inflammation with purulent material including structures displaying evidence of trematode infection. To investigate this further, medical records describing such cases in the Pudukkottai district, Tamil Nadu State, India, covering the period 2001-2005, were collected. Since trematodes require a snail intermediate host for completing the life cycle, ponds frequently used for bathing in the area were inspected to identify a possible culprit. The hypothesis that ponds with snail habitats could be the source of infection was supported by the finding of a positive correlation between the geographical distribution of patients’ residencies and the location of such ponds. Geographic information systems (GIS were used to study the spatial distribution of ponds and patients, while satellite-based remote sensing (RS was applied to attempt finding a parameter characteristic for ponds with snail habitats that could facilitate risk-identification over larger areas. It was found that ponds carrying risk could be differentiated from others through analysis of their spectral surface properties. This pond classification approach, confirmed by field visits, could thus become a useful tool for the location of snail habitats constituting risk as predicted.

    Full Text Available Background & objectives: Scrub typhus is a major public health threat in South and Southeastern Asian countries including India. Understanding local patterns of disease and factors that place individuals at risk is pivotal to future preventive measures against scrub typhus. The primary aim of this study was to identify specific epidemiological and geographical factors associated with an increased risk of developing scrub typhus in this region. Methods: We mapped 709 patients from Tamil Nadu, Andhra Pradesh and Telangana who were admitted to the Christian Medical College (CMC Hospital, Vellore, Tamil Nadu, India, for the period 2006-2011, assessed seasonality using monthly counts of scrub typhus cases, and conducted a case-control study among a subset of patients residing in Vellore. Results: The geographic distribution of cases at CMC Hospital clusters around the Tamil Nadu-Andhra Pradesh border. However, distinct hotspots clearly exist distal to this area, near Madurai and the coast in Tamil Nadu, and in the Northeast of Andhra Pradesh. Seasonally, the highest numbers of cases were observed in the cooler months of the year, i.e. September to January. In the case-control analysis, cases were more likely to be agricultural laborers (OR 1.79, 95% CI 1.01 - 3.15, not wear a shirt at home (OR 4.23, 95% CI 1.12 - 16.3, live in houses adjacent to bushes or shrubs (OR 1.95, 95% CI 1.08 - 3.53, and live in a single room home (OR 1.75, 95% CI 1.02 - 3.01. On binary logistic regression, the first three of these variables were statistically significant. Interpretation & conclusions: With the growing number of cases detected in India, scrub typhus is fast emerging as a public health threat and further research to protect the population from this deadly infection is essential. Health education campaigns focusing on the agricultural workers of Southern India, especially during the cooler months of the year, can serve as an important public health measure to

    This study examined salinization and desalinization in an agricultural area of Nagapatttinam district, Tamil Nadu state, India due to the December 2004 tsunami. To examine the damage and recovery of agricultural environment from the tsunami, we observed and collected soil, groundwater and vegetation data. Soil electrical conductivity steeply increased after the tsunami and soil pH slightly increased, but returned to pre-tsunami levels in the following year. Groundwater salinity might return to pre-tsunami levels by 2006. MODIS EVI values measured before and after the tsunami showed that vegetation damaged by the tsunami recovered to its pre-tsunami state by the next rice cropping season, called samba, which continues from August to February. These rapid rates of recovery were due to leaching salt from the highly permeable soils in the area by the monsoon rainfall. From these results, we conclude that agricultural environment of the district has mostly recovered one year after the tsunami.

    Full Text Available The study aimed to determine costs to the state government of implementing different interventions for controlling rabies among the entire human and animal populations of Tamil Nadu. This built upon an earlier assessment of Tamil Nadu's efforts to control rabies. Anti-rabies vaccines were made available at all health facilities. Costs were estimated for five different combinations of animal and human interventions using an activity-based costing approach from the provider perspective. Disease and population data were sourced from the state surveillance data, human census and livestock census. Program costs were extrapolated from official documents. All capital costs were depreciated to estimate annualized costs. All costs were inflated to 2012 Rupees. Sensitivity analysis was conducted across all major cost centres to assess their relative impact on program costs. It was found that the annual costs of providing Anti-rabies vaccine alone and in combination with Immunoglobulins was $0.7 million (Rs 36 million and $2.2 million (Rs 119 million, respectively. For animal sector interventions, the annualised costs of rolling out surgical sterilisation-immunization, injectable immunization and oral immunizations were estimated to be $ 44 million (Rs 2,350 million, $23 million (Rs 1,230 million and $ 11 million (Rs 590 million, respectively. Dog bite incidence, health systems coverage and cost of rabies biologicals were found to be important drivers of costs for human interventions. For the animal sector interventions, the size of dog catching team, dog population and vaccine costs were found to be driving the costs. Rabies control in Tamil Nadu seems a costly proposition the way it is currently structured. Policy makers in Tamil Nadu and other similar settings should consider the long-term financial sustainability before embarking upon a state or nation-wide rabies control programme.

    In this paper we discuss the limitation of radiocarbon dates on the pedogenic calcic nodules formed in situ within the vertisols in the upland region of Coimbatore, Tamil Nadu. The radiocarbon ages were obtained using low level scintillation counters and the ages range from ∼24 Ka to ∼31 Ka. The ages correlate well with the marine isotope stage of Late MIS3. Since the calcic nodules are pedogenised and formed in a terrestrial open system we express caution in the interpretation of the radiocarbon ages obtained on pedogenic carbonate nodules. The radiocarbon dates represent maximum ages and hence the ages measured should only be considered as age estimates and not absolute geologic ages. Multiple sub-mm size subsamples could provide more reliable estimates of soil chronology. (author)

    Toxicity due to excess fluoride concentration in drinking water is of great concern in people who rely only on the ground water as their water source in many region of the world. We collected samples and examined the toxicity of fluoride in a population residing at Salem, Dharmapuri and Krishnagiri districts of Tamil Nadu, India and measured HDL bound enzyme (PON1), erythrocyte membrane bound enzymes (acetylcholinesterase, AChE) and adenosine 5' triphosphatase (ATPases), plasma enzyme (butyrylcholinesterase, BChE) and rate limiting enzyme in heme biosynthesis (delta aminolevulinic acid dehydratase, δ-ALAD) activities. In fluorosis patients, formation of lipid peroxidation product was more in erythrocytes than in plasma. The observation further revealed that there was 50% reduction in the activity of HDL bound anti atherogenic enzyme-paraoxonase (PON1). The activities of membrane bound and signaling enzymes (acetylcholinesterase - AChE and adenosine 5' triphosphatase - ATPase) of erythrocyte were also diminished. These results suggested that there was defectiveness in the signaling and energy metabolism in fluorosis patients. Altered isoenzyme pattern of lactate dehydrogenase (LDH) in fluorosis samples was observed. Furthermore, the result suggested that both the heart (LDH 1) and liver (LDH 5) were most affected by fluoride toxicity. The study also provided reference values for tests which are used to predict the severity of fluoride toxicity. The toxic effect of fluoride was due to the collective effects on vital protective system rather than single factor. Copyright © 2017 Elsevier B.V. All rights reserved.

    Natural radioactivity content and heavy metal concentration in the intertidal zone sand samples from the southern region of Tamil Nadu coast, India, have been analyzed using gamma ray spectrometer and ICP-OES, respectively. From gamma spectral analysis, the average radioactivity contents of 238 U, 232 Th, and 40 K in the intertidal zone sand samples are 12.13±4.21, 59.03±4.26, and 197.03±26.24Bq/kg, respectively. The average radioactivity content of 232 Th alone is higher than the world average value. From the heavy metal analysis, the average Cd, Cr, Cu, Ni, Pb, and Zn concentrations are 3.1, 80.24, 82.84, 23.66, 91.67, and 137.07ppm, respectively. The average Cr and Ni concentrations are lower, whereas other four metal (Cd, Cu, Pb, and Zn) concentrations are higher than world surface rock average values. From pollution assessment parameter values, the pollution level is "uncontaminated to moderately contaminated" in the study area. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The natural level of radioactivity in building materials is one of the major causes of external exposure to γ-rays. The primordial radionuclides in building materials are one of the sources of radiation hazard in dwellings made of these materials. By the determination of the radioactivity level in building materials, the indoor radiological hazard to human health can be assessed. This is an important precautionary measure whenever the dose rate is found to be above the recommended limits. The aim of this work was to measure the specific activity concentration of (226)Ra, (232)Th and (40)K in commonly used building materials from Namakkal, Tamil Nadu, India, using gamma-ray spectrometer. The radiation hazard due to the total natural radioactivity in the studied building materials was estimated by different approaches. The concentrations of the natural radionuclides and the radium equivalent activity in studied samples were compared with the corresponding results of different countries. From the analysis, it is found that these materials may be safely used as construction materials and do not pose significant radiation hazards. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Studies have shown that social capital is positively associated with health, and the association is context-based. Indigenous populations with poor access to health care largely depend on social capital for their health care needs. This study was conducted to explore the dimensions and types of social capital and its utilization by families with thalassemia for their health and well-being in an indigenous population in Tamil Nadu, India. The participants in the study were parents who had children with thalassemia, belonged to an indigenous community in Tamil Nadu, were poor and marginalized, and had poor access to health care. Different dimensions and types of social capital were examined with the help of qualitative in-depth interviews using a phenomenological approach. A total of 8 in-depth interviews were conducted and transcribed. Thematic analysis of the data was performed. The social capital identified through the in-depth interviews consisted of various levels of family support, financial support from relatives and neighbors, the provision of information from formal and informal networks, and trust in the physician. Indigenous communities are close-knit due to their geographical remoteness and limited accessibility. Family ties were a form of social capital that encouraged bonding, and provided support and care to the children affected by thalassemia. The bonding also helped to meet the regular requirement of blood donation for the children. Relatives and neighbors were an asset that served as a bridge for the families affected, helping them in times of immediate and urgent financial need, making it easier to sustain long-term treatment and providing emotional support. There were informal networks that bridged parents belonging to indigenous and non-indigenous communities, with the latter providing the former with information to help them choose better health care at an affordable cost. The other formal links were the ties between the parents and

    Full Text Available Background and Aim: In Tamil Nadu, a southern state of India, rice is readily available at a low cost, hence, is cooked (cooking akin to human consumption and fed irrationally to cross-bred dairy cattle with poor productivity. Hence, a study was carried out with the objective to examine the prevalence of acidosis sequelae to rice-based feeding regimen and assess its magnitude. Materials and Methods: A survey was conducted in all the 32 districts of Tamil Nadu, by randomly selecting two blocks per districts and from each block five villages were randomly selected. From each of the selected village, 10 dairy farmers belonging to the unorganized sector, owning one or two cross-bred dairy cows in early and mid-lactation were randomly selected so that a sample size of 100 farmers per district was maintained. The feeding regimen, milk yield was recorded, and occurrence of acidosis and incidence of laminitis were ascertained by the veterinarian with the confirmative test to determine the impact of feeding cooked rice to cows. Results: It is observed that 71.5% of farmers in unorganized sector feed cooked rice to their cattle. The incidence of acidosis progressively increased significantly (p<0.05 from 29.00% in cows fed with 0.5 kg of cooked rice to 69.23% in cows fed with more than 2.5 kg of cooked rice. However, the incidence of acidosis remained significantly (p<0.05 as low as 9.9% in cows fed feeding regimen without cooked rice which is suggestive of a correlation between excessive feeding cooked rice and onset of acidosis. Further, the noticeable difference in the incidence of acidosis observed between feeding cooked rice and those fed without rice and limited intake of oil cake indicates that there is a mismatch between energy and protein supply to these cattle. Among cooked rice-based diet, the incidence of laminitis increased progressively (p<0.05 from 9.2% to 37.9% with the increase in the quantum of cooked rice in the diet. Conclusion: The

    Full Text Available The sediments of the beaches along the central coast of Tamil Nadu from Pondicherry to Vedaranyam were studied for their textural variation. 108 sediment samples collected from the low-, mid-, and high-tidal zones, as well as the berms and dunes of different beach morpho-units were analysed. The study area was divided into three sectors (northern, central and southern on the basis of prevailing energy conditions and oceanographic parameters. The poorly sorted, negatively skewed, coarser sediments of the northern sector are indicative of denudational processes taking place there. Medium-to-fine, moderately-to-well sorted, positive-symmetrically skewed sediments dominate the central sector, probably as a result of the influence of palaeo-sediments deposited by rivers from inland as well as by waves and currents from offshore. Fine, poorly sorted, positive-symmetrically skewed sediments dominate the southern sector, highlighting depositional processes. Linear Discriminant Function Analysis (LDF of the samples indicates a shallow marine environment origin for all the three sectors. These results show that reworked sediments, submerged during the Holocene marine transgression, are being deposited on present-day beaches by waves, currents and rivers in the study area.

    A three-month sabbatical allowed a superficial overview of Indian medical history and practice. As in Western nations, cost is a major determinant of health care delivery in India; poverty and fiscal shortages, however, deny care to many. The education of Indian physicians is similar to that in Western nations and a high level of clinical competence is seen. However, physician compensation is woefully low by Western standards. India possesses its own indigenous medical systems, purported to be the oldest in the world and predating Hippocrates by several millenia. Most Indians are cared for by native practitioners whose medical techniques are intricately related to the Hindu and Islamic religions. Many of their herbal medicines have been assimilated into contemporary Western practice. Diseases unknown to us except by textbooks are commonly seen and effectively treated. On the other hand, Western diseases such as coronary arteriosclerosis are not uncommon in a land of massive overpopulation and malnutrition. The humbling aspect of this experience is the realization that medical practice dating back several millenia can be made more modern and carried out competently by contemporary physicians. A Western physician working in India finds an unparalleled variety of disease in a totally different medical-religious environment allowing him to reorganize his priorities and to rediscover himself in the world within which he lives.

    The water quality study of Salem district, Tamil Nadu has been carried out to assess the water quality for domestic and irrigation purposes. For this purpose, 59 groundwater samples were collected and analyzed for pH, electrical conductivity (EC), total dissolved solids (TDS), major anions (HCO3 -, CO3 -, F-, Cl-, NO2 - + NO3 -, and SO4 2-), major cations (Ca2+ Mg2+, Na+, and K+), alkalinity (ALK), and hardness (HAR). To assess the water quality, the following chemical parameters were calculated based on the analytical results, such as Piper plot, water quality index (WQI), sodium adsorption ratio (SAR), magnesium hazard (MH), Kelly index (KI), and residual sodium carbonate (RSC). Wilcox diagram represents that 23% of the samples are excellent to good, 40% of the samples are good to permissible, 10% of the samples are permissible to doubtful, 24% of the samples are doubtful unsuitable, and only 3% of the samples are unsuitable for irrigation. SAR values shows that 52% of the samples indicate high-to-very high and low-to-medium alkali water. KI values indicate good quality (30%) and not suitable (70%) for irrigation purposes. RSC values indicate that 89% of samples are suitable for irrigation purposes. MH reveals that 17% suitable and 83% samples are not suitable for irrigation purposes and for domestic purposes the excellent (8%), good (48%), and poor (44%). The agricultural waste, fertilizer used, soil leaching, urban runoff, livestock waste, and sewages are the sources of poor water quality. Some samples are not suitable for irrigation purposes due to high salinity, hardness, and magnesium concentration. In general, the groundwater of the Salem district was polluted by agricultural activities, anthropogenic activities, ion exchange, and weathering.

    To determine the prevalence and risk factors of scrub typhus in Tamil Nadu, South India. We performed a clustered seroprevalence study of the areas around Vellore. All participants completed a risk factor survey, with seropositive and seronegative participants acting as cases and controls, respectively, in a risk factor analysis. After univariate analysis, variables found to be significant underwent multivariate analysis. Of 721 people participating in this study, 31.8% tested seropositive. By univariate analysis, after accounting for clustering, having a house that was clustered with other houses, having a fewer rooms in a house, having fewer people living in a household, defecating outside, female sex, age >60 years, shorter height, lower weight, smaller body mass index and smaller mid-upper arm circumference were found to be significantly associated with seropositivity. After multivariate regression modelling, living in a house clustered with other houses, female sex and age >60 years were significantly associated with scrub typhus exposure. Overall, scrub typhus is much more common than previously thought. Previously described individual environmental and habitual risk factors seem to have less importance in South India, perhaps because of the overall scrub typhus-conducive nature of the environment in this region. © 2017 John Wiley & Sons Ltd.

    Full Text Available India is experiencing energy crisis and a widening gap between energy supply and demand. The country is, however, endowed with considerable, commercially and technically available renewable resources, from which surplus agro-biomass is of great importance and a relatively untapped resource. In the policy making process, knowledge of existing biomass use, degree of social reliance, and degree of biomass availability for energy production is unequivocal and pre-conditional. Field observations, documentation, and fill-in sheet tools were used to investigate the potential of biomass resources and the existing domestic, commercial, and industrial uses of biomass in selected Indian states. To do so, a team of field observers/supervisors visited three Indian states namely: Maharashtra (MH, Madhya Pradesh (MP, and Tamil Nadu (TN. Two districts from each state were selected to collect data regarding the use of biomass and the extent of biomass availability for energy production. In total, 471 farmers were interviewed, and approximately 75 farmers with various land holdings have been interviewed in each district. The existing uses of biomass have been documented in this survey study and the results show that the majority of biomass is used as fodder for domestic livestock followed by in-site ploughing, leaving trivial surplus quantities for other productive uses. Biomass for cooking appeared to be insignificant due to the availability and access to Liquefied Petroleum Gas (LPG cylinders in the surveyed districts. Opportunities exist to utilize roadside-dumped biomass, in-site burnt biomass, and a share of biomass used for ploughing. The GIS-based maps show that biomass availability varies considerably across the Taluks of the surveyed districts, and is highly dependent on a number of enviromental and socio-cultural factors. Developing competitive bioenergy market and enhancing and promoting access to more LPG fuel connections seem an appropriate socio

    Fluorosis is one of the common but major emerging areas of research in the tropics. It is considered endemic in 17 states of India. However, the Cuddalore district of Tamil Nadu is categorised as a fluorosis non-endemic area. But clinical cases of dental fluorosis were reported in the field practice area of Department of Community Medicine, Rajah Muthiah Medical College, Annamalai University, Chidambaram. Since dental fluorosis has been described as a biomarker of exposure to fluoride, we assessed the prevalence and severity of dental fluorosis among primary school children in the service area. Children studying in six primary schools of six villages in the field practice area of Rural Health Centre of Faculty of Medicine, Annamalai University, Chidambaram, were surveyed. Every child was clinically examined at the school by calibrated examiners with Dean's fluorosis index recommended by WHO (1997). Chi-square test, Chi-square trend test and Spearman's rank correlation coefficient test were used for statistical analysis. Five hundred and twenty-five 5- to 12-year-old school children (255 boys and 270 girls) were surveyed. The overall dental fluorosis prevalence was found to be 31.4% in our study sample. Dental fluorosis increased with age P dental fluorosis was found in 2.1% of the sample. Villages Senjicherry, Keezhaperambai and Kanagarapattu revealed a community fluorosis index (CFI) score of 0.43, 0.54 and 0.54 with 5.6%, 4.8% and 1.4% of objectionable dental fluorosis, respectively. Correlation between water fluoride content and CFI values in four villages was noted to be positively significant. Three out of six villages studied were in 'borderline' public health significance (CFI score 0.4-0.6). A well-designed epidemiological investigation can be undertaken to evaluate the risk factors associated with the condition in the study region.

    Full Text Available Seasonal population trends of butterflies inhabiting the campus of Department of Atomic Energy (DAE at Kalpakkam were recorded by setting a permanent line transect of 300m and recording all species of butterflies observed within a 5m distance. The survey yielded 2177 individuals of 56 butterfly species, belonging to the families Nymphalidae, Pieridae, Lycaenidae, Papilionidae and Hesperiidae. Nymphalidae were found to be the dominant family during all seasons. Species richness and abundance were highest during the northeast monsoon and winter periods, indicating that in the southern plains of India butterflies prefer cool seasons for breeding and emergence. The taxonomic structure of the butterflies sampled resembles that of the Western Ghats and other regions of India in two ways: (a dominance of nymphalids and (b peak abundance during wet seasons. A detailed study of ecologically important local butterfly fauna and their host plants is in progress, to construct a butterfly garden in Kalpakkam to attract and support butterflies.

    Full Text Available The transportation system in Kanyakumari District has met the grim situation over the years due to numerous parameters like increasing population, increasing economic activity, increasing vehicular population, negligence from the administrative officials, unethical practices of the locals, etc.; led it to a pathetic condition, especially on National Highway-47. However, to simplify the situation, the National Highway Authority of India (NHAI, Government of India is taking up the effort for developing the new bypass road to the existing NH-47 by diverting form selected few junctions. Unfortunately, this partial solution for the existing NH-47 will give birth to numerous other physical, socio-economic, and ecological problems. The objectives of this study is to identify the possible causes of the inadequacies in prevailing transportation network of Kanyakumari District and put forward logical, scientific and economical conceptual level solutions for the betterment of road users and people of the district. In order to revamp the present dreadful condition, the authors have worked out some simple remedial measures as a solution by conducting exhaustive observation survey, analytical work, discussions with experts and the locals, etc. It includes assessing the prevailing conditions of transportation system in the district, proposing planning design options for rectifying the short comings of the transportation network of the district, conceptualization of the standard flyover design for the NH-47 and ring roads for selected towns of high importance. Further, the paper concludes with plausible and executable recommendations. It is recommended that, in the light of these findings of opportunities and possibilities, the administrative authorities and officials of Kanyakumari district might look into rejuvenating the road transportation scenario of the district.

    Full Text Available Background: Fluorosis is one of the common but major emerging areas of research in the tropics. It is considered endemic in 17 states of India. However, the Cuddalore district of Tamil Nadu is categorised as a fluorosis non-endemic area. But clinical cases of dental fluorosis were reported in the field practice area of Department of Community Medicine, Rajah Muthiah Medical College, Annamalai University, Chidambaram. Since dental fluorosis has been described as a biomarker of exposure to fluoride, we assessed the prevalence and severity of dental fluorosis among primary school children in the service area. Materials and Methods: Children studying in six primary schools of six villages in the field practice area of Rural Health Centre of Faculty of Medicine, Annamalai University, Chidambaram, were surveyed. Every child was clinically examined at the school by calibrated examiners with Dean′s fluorosis index recommended by WHO (1997. Chi-square test, Chi-square trend test and Spearman′s rank correlation coefficient test were used for statistical analysis. Results: Five hundred and twenty-five 5- to 12-year-old school children (255 boys and 270 girls were surveyed. The overall dental fluorosis prevalence was found to be 31.4% in our study sample. Dental fluorosis increased with age P < 0.001, whereas gender difference was not statistically significant. Aesthetically objectionable dental fluorosis was found in 2.1% of the sample. Villages Senjicherry, Keezhaperambai and Kanagarapattu revealed a community fluorosis index (CFI score of 0.43, 0.54 and 0.54 with 5.6%, 4.8% and 1.4% of objectionable dental fluorosis, respectively. Correlation between water fluoride content and CFI values in four villages was noted to be positively significant. Conclusion: Three out of six villages studied were in ′borderline′ public health significance (CFI score 0.4-0.6. A well-designed epidemiological investigation can be undertaken to evaluate the risk factors

    Full Text Available Abstract Background The burden of disease of hearing disorders among adults is high, but a significant part goes undetected. Screening programs in combination with the delivery of hearing aids can alleviate this situation, but the economic attractiveness of such programs is unknown. This study aims to evaluate the population-level costs, effects and cost-effectiveness of alternative delivering hearing aids models in Tamil Nadu, India Methods In an observational study design, we estimated total costs and effects of two active screening programs in the community in combination with the provision of hearing aids at secondary care level, and the costs and effects of the provision of hearing aids at tertiary care level. Screening and hearing aid delivery costs were estimated on the basis of program records and an empirical assessment of health personnel time input. Household costs for seeking and undergoing hearing health care were collected with a questionnaire (see Additional file 2. Health effects were estimated on the basis of compliance with the hearing aid, and associated changes in disability, and were expressed in disability-adjusted life years (DALYs averted. Results Active screening and provision of hearing aids at the secondary care level costs around Rs.7,000 (US$152 per patient, whereas provision of hearing aids at the tertiary care level costs Rs 5,693 (US$122 per patient. The cost per DALY averted was around RS 42,200 (US$900 at secondary care level and Rs 33,900 (US$720 at tertiary care level. The majority of people did consult other providers before being screened in the community. Costs of food and transport ranged between Rs. 2 (US$0,04 and Rs. 39 (US$0,83. Conclusion Active screening and provision of hearing aids at the secondary care level is slightly more costly than passive screening and fitting of hearing aids at the tertiary care level, but seems also able to reach a higher coverage of hearing aids services.

    Full Text Available The monitoring and evaluation of lymphatic filariasis (LF has largely relied on the detection of antigenemia and antibodies in human populations. Molecular xenomonitoring (MX, the detection of parasite DNA/RNA in mosquitoes, may be an effective complementary method, particularly for detecting signals in low-level prevalence areas where Culex is the primary mosquito vector. This paper investigated the application of a household-based sampling method for MX in Tamil Nadu, India.MX surveys were conducted in 2010 in two evaluation units (EUs: 1 a hotspot area, defined as sites with community microfilaria prevalence ≥1%, and 2 a larger area that also encompassed the hotspots. Households were systematically selected using a sampling interval proportional to the number of households in the EU. Mosquito pools were collected and analyzed by real-time polymerase chain reaction (qPCR. Two independent samples were taken in each EU to assess reproducibility of results. Follow-up surveys were conducted in 2012.In 2010, the proportion of positive pools in the hotspot EU was 49.3% compared to 23.4% in the overall EU. In 2012, pool positivity was significantly reduced to 24.3% and 6.5%, respectively (p<0.0001. Pool positivity based on independent samples taken from each EU in 2010 and 2012 were not significantly different except for the hotspot EU in 2012 (p = 0.009. The estimated prevalence of infection in mosquitoes, measured by PoolScreen, declined from 2.2-2.7% in 2010 to 0.6-1.2% in 2012 in the hotspot area and from 0.9-1.1% to 0.2-0.3% in the larger area.The household-based sampling strategy for MX led to mostly reproducible results and supported the observed LF infection trends found in humans. MX has the potential to be a cost-effective, non-invasive monitoring and evaluation tool with sensitive detection of infection signals in low prevalence settings. Further investigation and application of this sampling strategy for MX are recommended to support

    This study proposes to introduce the remote sensing and geographic information system (GIS) techniques in mapping the groundwater potential zones. Remote sensing and GIS techniques have been used to map the groundwater potential zones in Salem Chalk Hills, Tamil Nadu, India. Charnockites and fissile hornblende biotite gneiss are the major rock types in this region. Dunites and peridodites are the ultramafic rocks which cut across the foliation planes of the gneisses and are highly weathered. It comprises magnesite and chromite deposits which are excavated by five mining companies by adopting bench mining. The thickness of weathered and fracture zone varies from 2.2 to 50 m in gneissic formation and 5.8 to 55 m in charnockite. At the contacts of gneiss and charnockite, the thickness ranges from 9.0 to 90.8 m favoring good groundwater potential. The mine lease area is underlined by fractured and sheared hornblende biotite gneiss where groundwater potential is good. Water catchment tanks in this area of 5 km radius are small to moderate in size and are only seasonal. They remain dry during summer seasons. As perennial water resources are remote, the domestic and agricultural activities in this region depend mainly upon the groundwater resources. The mines are located in gently slope area, and accumulation of water is not observed except in mine pits even during the monsoon period. Therefore, it is essential to map the groundwater potential zones for proper management of the aquifer system. Satellite imageries were also used to extract lineaments, hydrogeomorphic landforms, drainage patterns, and land use, which are the major controlling factors for the occurrence of groundwater. Various thematic layers pertaining to groundwater existence such as geology, geomorphology, land use/land cover, lineament, lineament density, drainage, drainage density, slope, and soil were generated using GIS tools. By integrating all the above thematic layers based on the ranks and

    Full Text Available Ambur, a town located on the banks of Palar River, is considered one of the most polluted areas in India and occupied by hundreds of tanneries and leather product units. The present study was designed to evaluate the toxic effect of discharged tannery effluent (TE on model agricultural crops, ecofriendly microorganisms, and human blood cells. The phytotoxic effects of TE tested on Allium cepa and Lemna minor revealed inhibition of root growth and significant reduction in number of fronds, protein, and chlorophyll content. Moreover, TE induced chlorosis and tissue necrosis in Nostoc muscorum at low concentration (10%. TE has also negative impact on ecofriendly microorganisms, Bacillus thuringiensis, Rhizobium etli, and Aspergillus terreus which play an important role in the nutrition of plant growth. The genotoxicity of TE was investigated in human leukocytes which showed interference with normal mitotic division with subsequent cell lysis. It also intervened with the normal replication process and induced micronucleus formation in the healthy leukocyte. 5% concentration of TE has been revealed to be toxic to erythrocytes. From this study TE found in the Palar River of Ambur has adverse effects on all the three levels of organisms in ecosystem even at lower concentrations.

    Submarine groundwater discharge (SGD) is described as submarine inflow of fresh and brackish groundwater from land into the sea. The release of sewages from point and non-point source pollutants from industries, agricultural and domestic activities gets discharged through groundwater to ocean creating natural disparity like decreasing flora fauna and phytoplankton blooms. Hence, to quantify fluxes of SGD in coastal regions is important. Quantification of SGD was attempted in Coleroon estuary, India, using three dissimilar methods like water budget, Darcy law and manual seepage meter. Three seepage meters were installed at two prominent litho units (alluvium and fluvio marine) at a distance of (0-14.7 km) away from Bay of Bengal. The water budget and Darcy law-quantified submarine seepage at a rate of 6.9 × 106 and 3.2 × 103 to 308.3 × 103 m3 year-1, respectively, and the seepage meter quantified seepage rate of 0.7024 m h-1 at an average. Larger seepage variations were isolated from three different techniques and the seepage rates were found to be influenced by hydrogeological characteristics of the litho units and distance from the coast.

    The present hydrogeochemical study was confined to the Thoothukudi District in Tamilnadu, India. A total of 100 representative water samples were collected during pre-monsoon and post-monsoon and analyzed for the major cations (sodium, calcium, magnesium and potassium) and anions (chloride, sulfate, bicarbonate, fluoride and nitrate) along with various physical and chemical parameters (pH, total dissolved salts and electrical conductivity). Water quality index rating was calculated to quantify the overall water quality for human consumption. The PRM samples exhibit poor quality in greater percentage when compared with POM due to dilution of ions and agricultural impact. The overlay of WQI with chloride and EC corresponds to the same locations indicating the poor quality of groundwater in the study area. Sodium (Na %), sodium absorption ratio (SAR), residual sodium carbonate (RSC), residual sodium bicarbonate, permeability index (PI), magnesium hazards (MH), Kelly's ratio (KR), potential salinity (PS) and Puri's salt index (PSI) and domestic quality parameters such as total hardness (TH), temporary, permanent hardness and corrosivity ratio (CR) were calculated. The majority of the samples were not suitable for drinking, irrigation and domestic purposes in the study area. In this study, the analysis of salinization/freshening processes was carried out through binary diagrams such as of mole ratios of {SO}_{ 4}^{ 2- } /Cl- and Cl-/EC that clearly classify the sources of seawater intrusion and saltpan contamination. Spatial diagram BEX was used to find whether the aquifer was in the salinization region or in the freshening encroachment region.

    Basic chemicals and their related products like petrochemicals, fertilisers, paints, varnishes, glass, perfumes, toiletries, pharmaceuticals, etc. form a very significant part of the Indian economy and account for about 3% of India's GDP. Among the most diversified industrial sectors, it covers an array of more than 70,000 commercial products. The chemicals sector accounts for about 14% in overall index of industrial production, 11% of total exports and about 7.2% of total imports. The total Foreign Direct Investment in Chemicals (excluding fertilizers) was US 7252 million from April 2011 to March 2012. For inclusive growth and sustainable development most of the Chemical manufacturers should adopt the Cluster Development Approach. The objective is to Study the Occupational Hazards in Cashew Nut Shell Liquid (CNSL) Oil Processing Industries in Panruti Block of Cuddalore District. The methodology adopted is collection of primary processing data during November 2012 from 14 CNSL Processing Industries in Panruti Block of Cuddalore District. Majority of Industries has not processed the CNSL oil as per standards and there is much scope for occupational hazards. In two processes the CNSL oil is let out in the tank constructed equal to ground height where there is possibility of workers getting trapped inside the high temperature CNSL oil. The electric motor is also placed in the ground so that there is possibility of current passing in the ground which leads to occupational hazards for the workers. To conclude, Cashew Shell Oil Processing Industries in Panruti Block of Cuddalore District needs is re-engineering in design and operation starting from Cashew Shell storage, extraction of shell oil from expeller, processing and packaging of CNSL in barrels for better safety from occupational hazards and Cyclones. Moreover for sustainable development, they should adopt cluster development approach, so that infrastructure interrelationships, technology interrelationships

    Full Text Available Abstract Local knowledge systems are not considered in the conservation of fragile seagrass marine ecosystems. In fact, little is known about the utility of seagrasses in local coastal communities. This is intriguing given that some local communities rely on seagrasses to sustain their livelihoods and have relocated their villages to areas with a rich diversity and abundance of seagrasses. The purpose of this study is to assist in conservation efforts regarding seagrasses through identifying Traditional Ecological Knowledge (TEK from local knowledge systems of seagrasses from 40 coastal communities along the eastern coast of India. We explore the assemblage of scientific and local traditional knowledge concerning the 1. classification of seagrasses (comparing scientific and traditional classification systems, 2. utility of seagrasses, 3. Traditional Ecological Knowledge (TEK of seagrasses, and 4. current conservation efforts for seagrass ecosystems. Our results indicate that local knowledge systems consist of a complex classification of seagrass diversity that considers the role of seagrasses in the marine ecosystem. This fine-scaled ethno-classification gives rise to five times the number of taxa (10 species = 50 local ethnotaxa, each with a unique role in the ecosystem and utility within coastal communities, including the use of seagrasses for medicine (e.g., treatment of heart conditions, seasickness, etc., food (nutritious seeds, fertilizer (nutrient rich biomass and livestock feed (goats and sheep. Local communities are concerned about the loss of seagrass diversity and have considerable local knowledge that is valuable for conservation and restoration plans. This study serves as a case study example of the depth and breadth of local knowledge systems for a particular ecosystem that is in peril. Key words: local health and nutrition, traditional ecological knowledge (TEK, conservation and natural resources management, consensus

    Rapid debris flows, a mixture of unconsolidated sediments and water travelling at speeds > 10 m/s are the most destructive water related mass movements that affect hill and mountain regions. The predisposing factors setting the stage for the event are the availability of materials, type of materials, stream power, slope gradient, aspect and curvature, lithology, land use and land cover, lineament density, and drainage. Rainfall is the most common triggering factor that causes debris flow in the Palar subwatershed and seismicity is not considered as it is a stable continental region and moderate seismic zone. Also, there are no records of major seismic activities in the past. In this study, one of the less explored heuristic methods known as the analytical network process (ANP) is used to map the spatial propensity of debris flow. This method is based on top-down decision model and is a multi-criteria, decision-making tool that translates subjective assessment of relative importance to weights or scores and is implemented in the Palar subwatershed which is part of the Western Ghats in southern India. The results suggest that the factors influencing debris flow susceptibility in this region are the availability of material on the slope, peak flow, gradient of the slope, land use and land cover, and proximity to streams. Among all, peak discharge is identified as the chief factor causing debris flow. The use of micro-scale watersheds demonstrated in this study to develop the susceptibility map can be very effective for local level planning and land management.

The objective of the study was to assess the association of dental caries with family background, dental service availability, transportation and knowledge on preventive dental measures among these three groups. Cross-sectional study. A total of 1028 school children in the age range of 9-12 years from various government schools located in Palamalai and Kolli Hills (tribal), Tiruchengode (suburban) and Erode (urban), Tamil Nadu, were included in the study. Decayed, filled, and missing teeth (DMFT), decayed and filled teeth (dft) and Significant Caries Index were recorded. A specially prepared questionnaire was used to record all the data regarding oral hygiene practices, socioeconomic background, dental treatment availability, parent's education level were used for the study. ANOVA t-test and post hoc test were used for comparing quantitative variables between the 3 subgroups. The tribal school children had 89.3% caries prevalence, where as it was 77% in suburban and 55% in urban school children. The mean DMFT score among tribal, suburban and urban school children were statistically significant different (P=0.001) between the three groups. There was a highly significant difference (P=0.001) in the mean DMFT score based on brushing frequency. There was a statistically significant difference (P=0.018) in the mean DMFT scores in the urban group based on the mothers education status. There were no statistically significant differences in the mean DMFT scores based on the presence or absence of television in their house and the parents' income. Oral hygiene practices, dietary habits and access to dental care services played an important role in prevalence of dental caries. It was observed that the socioeconomic status, parents' educational status and mass media influenced the oral health of these children but

    Samples were collected in hard rock region central parts of Tamilnadu, South India to assess the U and 222 Rn levels in groundwater belonging to various lithologies and evaluate their correlations with other water quality parameters. The order of dominance of U in groundwater is; Granite> Charnockite> Fissile Hornblende biotite gneiss> Flood Plain Alluvium> Quartzite, while that of 222 Rn is: Granite> Quartzite> Charnockite > Fissile Hornblende biotite gneiss> Flood Plain Alluvium. Both U and 222 Rn concentrations were compared with drinking water standards and a few samples show levels above the permissible limits. High degree of weathering of granitic rocks and long contact time of groundwater with the aquifer matrix could be the reason for enhanced U and 222 Rn levels in groundwater. (author)

    Full Text Available Background. The study was planned to assess the prevalence of dental caries among tribal, suburban and urban children of Tiruchengode and Erode of Tamil Nadu state, India. The objective of the study was to assess the association of dental caries with family background, dental service availability, transportation and knowledge on preventive dental measures among these three groups. Design and methods. Cross-sectional study. A total of 1028 school children in the age range of 9-12 years from various government schools located in Palamalai and Kolli Hills (tribal, Tiruchengode (suburban and Erode (urban, Tamil Nadu, were included in the study. Decayed, filled, and missing teeth (DMFT, decayed and filled teeth (dft and Significant Caries Index were recorded. A specially prepared questionnaire was used to record all the data regarding oral hygiene practices, socioeconomic background, dental treatment availability, parent’s education level were used for the study. ANOVA t-test and post hoc test were used for comparing quantitative variables between the 3 subgroups. Results. The tribal school children had 89.3% caries prevalence, where as it was 77% in suburban and 55% in urban school children. The mean DMFT score among tribal, suburban and urban school children were statistically significant different (P=0.001 between the three groups. There was a highly significant difference (P=0.001 in the mean DMFT score based on brushing frequency. There was a statistically significant difference (P=0.018 in the mean DMFT scores in the urban group based on the mothers education status. There were no statistically significant differences in the mean DMFT scores based on the presence or absence of television in their house and the parents’ income. Conclusions. Oral hygiene practices, dietary habits and access to dental care services played an important role in prevalence of dental caries. It was observed that the socioeconomic status, parents’ educational

    The present study attempts to understand the form and geomorphic/hydrologic processes of the 20 watersheds of the Pachamalai hills and its adjoinings located in Tamil Nadu State of southern India from the analysis of its drainage morphometric characteristics. Survey of India's topographic sheets of 1:50,000 is the data source from which stream networks and watersheds of the study area were demarcated followed by the analysis of their morphometric characteristics using ArcGIS software. The results of the analysis formed the basis for deducing the form and processes of the watersheds of the study area. The form of the watersheds inferred from the analysis includes shape, length, slope steepness and length, degree of branching of streams, dissection and elongation of watersheds. The geomorphic/hydrologic processes inferred include denudation rate, potential energy, intensity of erosion, mean annual run off, mean discharge, discharge rate, rock resistivity and infiltration potential, amount of sediment transported, mean annual rainfall, rainfall intensity, lagtime, flash flood potential, flood discharge per unit area, sediment yield and speed of the water flow in the streams. The understanding of variations of form and processes mentioned can be used towards prioritizing the watersheds for development, management and conservation planning.

    Women's control over their own bodies and reproduction is a fundamental prerequisite to the achievement of sexual and reproductive health and rights. A woman's ability to terminate an unwanted pregnancy has been seen as the exercise of her reproductive rights. This study reports on interviews with 15 women in rural South India who had a medical abortion. It examines the circumstances under which they chose to have an abortion and their perspectives on medical abortion. Women in this study decided to have an abortion when multiple factors like lack of spousal support for child care or contraception, hostile in-laws, economic hardship, poor health of the woman herself, spousal violence, lack of access to suitable contraceptive methods, and societal norms regarding reproduction and sexuality converged to oppress them. The availability of an easy and affordable method like medical abortion pills helped the women get out of a difficult situation, albeit temporarily. Medical abortion also fulfilled their special needs by ensuring confidentiality, causing least disruption of their domestic schedule, and dispensing with the need for rest or a caregiver. The study concludes that medical abortion can help women in oppressive situations. However, this will not deliver gender equality or women's empowerment; social conditions need to change for that.

    Radiation exposure and effective dose received through two routes of exposure, viz. external and internal, via inhalation, by residents of 10 villages belonging to Natural High Background Radiation Areas (NHBRA) of coastal regions of Kanyakumari District and Tamil Nadu in India were studied. While the indoor gamma radiation levels were monitored using Thermo Luminescent Dosimeters (TLDs), the indoor radon and thoron gas concentrations were measured using twin chamber dosimeters employing Solid State Nuclear Track Detectors (SSNTDs, LR-115-II). The average total annual effective dose was estimated and found to be varying from 2.59 to 8.76 mSv. -- Highlights: {yields} The effective dose received by the villages of Natural High Background Area (NHBRA) such as Enayam, Midalam and Mel Midalam is high when compared with other study areas. {yields} The high dose indicates higher concentration of radioactive nuclides like Thorium and Uranium in the soil. {yields} As radiation is harmful to human life, the external and internal doses can be reduced by removing the monazite content present in the soil by mineral separation. {yields} Contribution from vegetables, fruits, fish and other non vegetarian items are also being examined. {yields} These results along with other socio-economic factors can throw considerable light on the epidemiological impacts due to low levels of chronic exposure.

  20. Impact of leachate on groundwater pollution due to non-engineered municipal solid waste landfill sites of erode city, Tamil Nadu, India

    Full Text Available Abstract Leachate and groundwater samples were collected from Vendipalayam, Semur and Vairapalayam landfill sites in Erode city, Tamil Nadu, India, to study the possible impact of leachate percolation on groundwater quality. Concentrations of various physicochemical parameters including heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, Fe and Zn were determined in leachate samples and are reported. The concentrations of Cl-, NO3-, SO42-, NH4+ were found to be in considerable levels in the groundwater samples particularly near to the landfill sites, likely indicating that groundwater quality is being significantly affected by leachate percolation. Further they were proved to be the tracers for groundwater contamination near Semur and Vendipalayam dumpyards. The presence of contaminants in groundwater particularly near the landfill sites warns its quality and thus renders the associated aquifer unreliable for domestic water supply and other uses. Although some remedial measures are suggested to reduce further groundwater contamination via leachate percolation, the present study demands for the proper management of waste in Erode city.

    The objectives of this study are to determine the prevalence of domestic accidents, describe the factors associated with domestic accidents and assess the medical and economical consequences of domestic accidents. Community-based cross-sectional study was conducted in a semi-urban area of Tamil Nadu during February 2013. A total of 3947 study participants were interviewed using a structured questionnaire. Study variables included were socio-demography, housing conditions, epidemiological factors, medical and economical consequences of domestic accidents. Means and proportions were calculated. The prevalence of domestic accidents was 12.7%. Out of 500 domestic accidents, falls (54.4%) was the most common type of domestic accident. Females and the respondents in age group of 21-40 years were more commonly affected. About 60% of victims received treatment. Mean duration of hospital stay, mean amount of money spent for treatment and mean number of days away from routine work for falls category were 16 days, US$25 and 8 days, respectively, which are higher than other types of accidents. The burden and impact of domestic accidents was high. Therefore, in order to prevent and control domestic accidents, promotion of house safety measures and creation of awareness among the community using IEC programmes have to be undertaken.

    Lack of consistent water availability for irrigated agriculture is recognized as one of the primary constraints to meeting the UN Millennium Development Goals to alleviate hunger, and in semi-arid landscapes such as those of southern India, which are characterized by high intra-annual variability in rainfall, provision of capabilities for seasonal storage is recognized to be one of the key strategies towards alleviating water scarcity problems and ensuring food security. Although the issue of increased storage can be addressed by centralized infrastructure projects such as large-scale irrigation systems and dams, an alternative is the "soft path" approach, in which existing large-scale projects are complemented by small-scale, decentralized solutions. Such a decentralized approach has been utilized in southern India for thousands of years in the form of village rainwater harvesting tanks or ponds, providing a local and inherently sustainable approach to providing sufficient water for rice cultivation. Over the last century, however, large-scale canal projects and groundwater pumping have replaced rainwater harvesting as the primary source of irrigation water. But with groundwater withdrawals now exceeding recharge in many areas and water tables continuing to drop, many NGOs and government agencies are advocating for a revival of the older rainwater harvesting systems. Questions remain, however, regarding the limits to which rainwater harvesting can provide a solution to decades of water overexploitation. In the present work, we have utilized secondary data sources to analyze the linkages between the tank irrigation systems and the village communities that depend on them within the Gundar Basin of southern Tamil Nadu. Combining socioeconomic data with information regarding climate, land use, groundwater depletion, and tank density, we have developed indicators of sustainability for these systems. Using these indicators, we have attempted to unravel the close

    Full Text Available In Tamil Nadu, one of the most populated states in the South of India, the relationship between cinema, television and politics can explain the success of some of its political leaders. Leaders who started their public activity as directors, actors or script writers, activities which they were successfully able to combine with their roles as public servants. The ethnical and religious diversity of this region, along with the unswayable support of their groups of fans, gave birth to the creation of nationalist political parties which do not hesitate to defend their cultural idiosyncrasy as a sign of social identity. The political game in Tamil Nadu highlights the importance that media, and especially cinema, has had since the forties and fifties of the twentieth century in shaping the political scene. This article, with a historical perspective, has as an objective to determine the turning points of this complex relationship between audiovisual and politics, correlation characteristic of Tamil Nadu but also of India as a whole.

    India has the highest absolute number of maternal deaths, preterm birth cases, and under-5 mortality in the world, as well as high domestic violence (DV) rates. We sought to examine the impact of DV and its psychosocial correlates on pregnancy and birth outcomes. Women seeking antenatal care in Tamil Nadu, South India (N = 150) were assessed during pregnancy, and birth outcomes were abstracted from medical records after the babies were born. We found that psychological abuse (OR 3.9; 95% CI 1.19-12.82) and mild or greater depressive symptoms (OR 3.3; 95% CI 0.99-11.17) were significantly associated with increased risk of preterm birth. Physical abuse was also associated with increased risk of preterm birth, but this was not statistically significant (OR 1.9; 95% CI 0.59-6.19). In each of the above adjusted models, low maternal education was associated with increased risk of preterm birth, in the analysis with depressive symptoms OR 0.18, CI 0.04-0.86 and in the analyses with psychological abuse OR 0.19, CI 0.04-0.91. These findings suggest that future research should focus on understanding the psychosocial antecedents to preterm birth, to better target interventions and improve maternal child health in limited resource settings.

    In India, the significant increase in the generation of municipal solid waste (MSW) during the last few decades is due to the rapid population and economic development. Though the appropriate attempts are made through the 3-'R' principles, waste management still needs to be envisaged seriously by everybody for a cleaner and greener environment. Rag-pickers, who contribute to solid waste management to some extent, are the people who rummage through garbage bins to pick out 'rags' for their livelihood. These rag-pickers usually collect the materials that have good re-sale value as these materials are mostly recycled or reused. In the present study, the collection and the management of solid waste and the level of microbial pollution generated through air, soil and solid waste were studied. A questionnaire survey based on age, sex, educational status, socio-economic status, habits and health effects was conducted from 65 randomly selected rag-pickers from various places of Tiruchirappalli city The results revealed that they can be properly educated and trained to protect themselves from unhygienic practices and addiction. Either the Government or non-governmental organizations (NGOs) should devise a suitable proposal to monitor and make use of these unorganized rag-pickers who are indispensable to the society.

    Full Text Available Background: Sexually transmitted infections (STIs are now recognized as a serious global threat to the health of population. Objectives: To assess the prevalence of sexually transmitted infections among young married scheduled castes women in Thiruvarur district of Tamilnadu state in India. Methods: A community based cross-sectional study was conducted in 28 villages selected using multistage sampling technique for selecting 605 women in the age group of 15-24 years during July 2010-April 2011. Data analysis was by use of SPSS version-17, with statistical significance set at p-value of 0.05. Results: Around 8.8% of women experienced sexually transmitted infections among the study population. The proportion of women who experienced STIs was seven times higher among illiterates (46.9% than women who completed secondary education (6%. The women in households in the high standard of living index (SLI were less likely to experience STIs (1.7% than women in low SLI (15.6%. The agricultural laborers were 1.145 times more likely to experience STIs than non-agricultural workers (OR=0.251. Conclusions: The main causes for sexual health problems were found to be the less education and lowest SLI among women. It is recommended that policy makers should be introduce community intervention programs to increase the awareness regarding sexual health issues among rural population.

    Close-Range Photogrammetry is an accurate, cost effective technique of collecting measurements of real world objects and conditions, directly from photographs. Photogrammetry utilizes digital images to obtain accurate measurements and geometric data of the object or area of interest, in order to provide spatial information for Engineering design, spatial surveys or 3D modeling. The benefits of close-range Photogrammetry over other field procedures are purported to be: Increased accuracy; complete as-built information; reduced costs; reduced on-site time; and effective for small and large projects. The same basic principle of traditional Aerial Photogrammetry can be applied to stereoscopic pictures taken from lower altitudes or from the ground. Terrestrial, ground-based, and close-range are all descriptive terms that refer to photos taken with an object-to-camera distance less than 300m (1000 feet). (Matthews, N.A, 2008). Close range Photogrammetry is a technique for obtaining the geometric information (e.g. position, distance, size and shape) of any object in 3D space that was imaged on the two dimensional (2D) photos, (Wolf, P.R, et.al, 2000) DEM Generation requires many processing and computation, such as camera calibration, stereo matching, editing, and interpolation. All the mentioned steps contribute to the quality of DEM. Image on close range Photogrammetry can be captured using three kind of camera: metric camera, semi-metric camera, and non-metric camera (Hanke, K., et.al, 2002). In this paper DEM quality assessed at Kadavur area, Karur district, Tamil Naudu, India using Close Range Photogrammetry technique, Commercial Digital Camera and Leica Photogrammetry Suite.

    Groundwater is the most important natural resource which cannot be optimally used and sustained unless its quality is properly assessed. In the present study, the spatial and temporal variations in physicochemical quality parameters of groundwater of Araniar River Basin, India were analyzed to determine its suitability for drinking purpose through development of drinking water quality index (DWQI) maps of the post- and pre-monsoon periods. The suitability for drinking purpose was evaluated by comparing the physicochemical parameters of groundwater in the study area with drinking water standards prescribed by the World Health Organization (WHO) and Bureau of Indian Standards (BIS). Interpretation of physicochemical data revealed that groundwater in the basin was slightly alkaline. The cations such as sodium (Na(+)) and potassium (K(+)) and anions such as bicarbonate (HCO3 (-)) and chloride (Cl(-)) exceeded the permissible limits of drinking water standards (WHO and BIS) in certain pockets in the northeastern part of the basin during the pre-monsoon period. The higher total dissolved solids (TDS) concentration was observed in the northeastern part of the basin, and the parameters such as calcium (Ca(2+)), magnesium (Mg(2+)), sulfate (SO4 (2-)), nitrate (NO3 (-)), and fluoride (F(-)) were within the limits in both the seasons. The hydrogeochemical evaluation of groundwater of the basin demonstrated with the Piper trilinear diagram indicated that the groundwater samples of the area were of Ca(2+)-Mg(2+)-Cl(-)-SO4 (2-), Ca(2+)-Mg(2+)-HCO3 (-) and Na(+)-K(+)-Cl(-)-SO4 (2-) types during the post-monsoon period and Ca(2+)-Mg(2+)-Cl(-)-SO4 (2-), Na(+)-K(+)-Cl(-)-SO4 (2-) and Ca(2+)-Mg(2+)-HCO3 (-) types during the pre-monsoon period. The DWQI maps for the basin revealed that 90.24 and 73.46% of the basin area possess good quality drinking water during the post- and pre-monsoon seasons, respectively.

    Full Text Available This article reports on a Public Private Partnership (PPP program in South India that provided information and communication technology (ICT to rural elementary schools. The article examined the current status of rural, government-run elementary schools in India by reviewing reports like the Annual Status of Education Report (ASER in India. Challenges like teacher absences, student drop-outs, lack of electricity, lack of separate toilets for genders, and a lack of teaching resources is discussed. To meet these challenges, the article describes the rise in popularity of India’s PPPs. Then the article reports on a case study of a PPP, called the SSA Foundation, which implemented a “one laptop per school” program in rural areas in the Indian States of Karnataka and Tamil Nadu. Using ethnographic data from field research, the case study includes a description of how the students in a rural Karnataka elementary school use their school’s laptop. The school was situated in a small village where most travel was non-motorized. Walking, usually without shoes, was the main form of transportation. A bicycle was considered a luxury. Most villagers worked in the surrounding ragi and millet fields; laboring, often with only simple tool blades. Wood fires were the main source of fuel for cooking. In this village, the school’s laptop became a prized possession. The case study offers a “thick description” (Geertz, 1973 of how the village school’s students used the laptop for learning basic computing skills and for learning English.

    Full Text Available One hundred and seven species of alkalotolerant fungi were isolated from different layers of litter of the Guindy Reserve Forest, Chennai, South India during a 2-year period. They comprised Zygomycota (7 species, Ascomycetes (4 species, hyphomycetes (86 species and coelomycetes (10 species. The F1 litter layer, just beneath the recently fallen leaves, had the richest composition of fungi and the fungi were most abundant during the North East monsoons (September to November. Shannon's diversity index and Simpson diversity index λ indicate F1 layer to have the maximum species. The species distribution fell into the log series model and Fishers alpha was also highest for the F1 layer. Species richness indices computed also indicated that none of the species was more predominant. Values of species evenness computed hovered around 0.6 indicating a tilt towards even distribution of the species. The fungal community is a heterogenous assembly of species derived from a homogenous habitat with a log normal pattern of distribution formed due to the interplay of many independent factors governing the relative abundance of the species. Principal component ordination analysis reveals that the greatest variation in the species composition was due to the South West monsoon. Also, detrended correspondence data put the species abundance data for the four seasons in a linear arrangement.

    Full Text Available The Pachamalai Hills are a part of the Eastern Ghats and are situated in the central region of Tamil Nadu. The vegetated area is distributed into 35 reserved forests of Pachamalai Hills. The plant Decalepis hamiltonii Wight & Arn. is one of the threatened plant found in the study area. This indicates that the Pachamalai Hills can harbour good vegetation which are the vestiges of a luxuriant vegetation cover of the past era, hence, need to be protected. The hills are most significant socio-culturally because of the diversified forest patches found there. These hills have been studied earlier mainly for floristic analysis. Before this, D. hamiltonii has not been collected from Pachamalai.

    Cervical cancer is the second common type of cancer among women worldwide, with the human papillomavirus (HPV) recognized as the major causative agent. The HPV 16/18 prevalance in cervical cancer patients from the Trichy and Coimbatore districts of Tamil Nadu state, India, was evaluated in addition to an assessment of oxidative stress and antioxidant status. MDA, GSH, GPx, GST, SOD, vitamin C and vitamin E were estimated in the plasma and erythrocytes of the twenty patients and an equal number of age matched normal subjects as controls. 119 paraffin embedded tissue samples were collected to perform DNA extraction and genotyping of HPV 16/18 using specific primers. Plasma and erythrocyte TBARS level was significantly elevated in the cervical cancer patients compared to normal. It was observed that SOD, GPx, GSH levels in the erythrocyte and plasma was significantly lower in cervical cancer patients, as well as GST and Vitamins E and C levels in the plasma and catalase enzyme levels in the erythrocytes. Genotyping showed 57% positive for HPV16 and 18% for HPV18, indicating that vaccination against these two will effectively reduce the burden associated with the disease. These findings suggest possible use of antioxidant supplementation as prophylactic agents for prevention and treatment of cervical cancer.

    Fuel energy demand is of great concern in recent times due to the depletion of fossil fuel resources. Biomass serves as widely available primary renewable energy source. Hence, a study was performed to assess the above-ground biomass yielding capability of fuel wood tree Prosopis juliflora in three varied ecosystems viz., coastal, fallow land and riparian ecosystems in southern districts of Tamil Nadu. The results showed that the biomass production potential and above-ground net primary productivity of P. juliflora depend on the age of the tree stands and the nature of ecosystem. A higher biomass yield was observed for P. juliflora trees with 5 to 10 years old when compared to less than 5 years of their age. Among the three ecosystems, the maximum biomass production was recorded in riparian ecosystem. The stands with less than 5-year-old P. juliflora trees gave 1.40 t/ha, and 5- to 10-year-old tree stands produced 27.69 t/ha in riparian ecosystem. Above-ground net primary productivity of both the age groups was high in fallow land ecosystem. In riparian ecosystem, the wood showed high density and low sulphur content than the other two ecosystems. Hence, P. juliflora biomass can serve as an environmentally and economically feasible fuel as well as their utilization proffers an effective means to control its invasiveness.

    Full Text Available Maintenance of wild animals in captivity is fraught with numerous challenges, including the control of disease. This study evaluates the effect of season, host demography (age-sex, and differing management systems on the prevalence of intestinal parasites among elephants managed in three captive systems: temple, private, and forest department, in Tamil Nadu. In addition, the study also assessed the availability of veterinary care for elephants in these systems. The parasitic prevalence was evaluated by direct microscopic identification of helminth eggs in faecal samples (n = 115 collected from different age/sex classes of elephants. Of the 115 elephants examined, 37% showed positive results, being infected only with Strongyles sp. The prevalence rate varied significantly across seasons, with the highest rate during summer (49% followed by monsoon (41% and the lowest rate during winter (15%. While males had a significantly lower parasite prevalence compared to females (29% vs. 40%, age classes showed no significant difference. Despite the fact that the proportion of animals receiving veterinary care was higher under the forest department system (100% compared to the private system (26%, parasite prevalence was significantly higher under the former (48% than the latter (31% system. The difference in the proportion of animals with parasitic prevalence among the three systems could be due to differing management practices (i.e. in solitary versus groups and the details are discussed.

    Komendantova, Nadejda; Patt, Anthony

    2013-04-01

    In December 2004, a multiple hazards event devastated the Tamil Nadu province of India. The Sumatra -Andaman earthquake with a magnitude of Mw=9.1-9.3 caused the Indian Ocean tsunami with wave heights up to 30 m, and flooding that reached up to two kilometers inland in some locations. More than 7,790 persons were killed in the province of Tamil Nadu, with 206 in its capital Chennai. The time lag between the earthquake and the tsunami's arrival in India was over an hour, therefore, if a suitable early warning system existed, a proper means of communicating the warning and shelters existing for people would exist, than while this would not have prevented the destruction of infrastructure, several thousands of human lives would have been saved. India has over forty years of experience in the construction of cyclone shelters. With additional efforts and investment, these shelters could be adapted to other types of hazards such as tsunamis and flooding, as well as the construction of new multi-hazard cyclone shelters (MPCS). It would therefore be possible to mitigate one hazard such as cyclones by the construction of a network of shelters while at the same time adapting these shelters to also deal with, for example, tsunamis, with some additional investment. In this historical case, the failure to consider multiple hazards caused significant human losses. The current paper investigates the patterns of the national decision-making process with regards to multiple hazards mitigation measures and how the presence of behavioral and cognitive biases influenced the perceptions of the probabilities of multiple hazards and the choices made for their mitigation by the national decision-makers. Our methodology was based on the analysis of existing reports from national and international organizations as well as available scientific literature on behavioral economics and natural hazards. The results identified several biases in the national decision-making process when the

    Full Text Available Context: Globally, about 17 million people die of cardiovascular diseases (CVDs every year and a substantial number of these deaths are attributed to four major risk factors namely unhealthy diet, physical inactivity, tobacco consumption, and alcohol consumption. Doctors and nurses often have a sedentary lifestyle. Aims: This study aimed at assessing the lifestyle-associated risk for CVDs among doctors and nurses in a medical college hospital. Setting and Design: Cross-sectional study among 250 doctors and nurses, selected using a stratified random sampling, working at a medical college hospital in Tamil Nadu. Subjects and Methods: After consenting, each participant answered a questionnaire comprising questions pertaining to the sociodemographic characteristics as well as lifestyle-related risk factors. Risk was categorized into low, moderate, and high based on general risk factors, physical activity risk factors, and dietary risk factors separately. Statistical Analysis: Descriptive statistics and Chi-square analysis were used to analyze the data. Results: It was found that 31.2% of all study subjects and 49.2% of doctors were at high general risk for CVDs; 30.4% of all study subjects and 42.1% of doctors were at high physical activity-related risk for CVDs; 14.4% of all study subjects and 19.8% of all doctors were at high dietary pattern-related risk for CVDs. Advancing age is a statistically significant risk factor across all risk groups. Conclusions: Doctors are at a higher risk for CVDs as compared to nurses as well as the general population.

    Radiation safety in computed tomography (CT) scanners is of concern due its widespread use in the field of radiological imaging. This study intends to evaluate radiation doses imparted to patients undergoing thorax, abdomen and pelvic CT examinations and formulate regional diagnostic reference levels (DRL) in Tamil Nadu, South India. In-site CT dose measurement was performed in 127 CT scanners in Tamil Nadu for a period of 2 years as a part of the Atomic Energy Regulatory Board (AERB)-funded project. Out of the 127 CT scanners,13 were conventional; 53 single-slice helical scanners (SSHS); 44 multislice CT (MSCT) scanners; and 17 refurbished scanners. CT dose index (CTDI) was measured using a 32-cm polymethyl methacrylate (PMMA)-body phantom in each CT scanner. Dose length product (DLP) for different anatomical regions was generated using CTDI values. The regional DRLs for thorax, abdomen and pelvis examinations were 557, 521 and 294 mGy cm, respectively. The mean effective dose was estimated using the DLP values and was found to be 8.04, 6.69 and 4.79 mSv for thorax, abdomen and pelvic CT examinations, respectively. The establishment of DRLs in this study is the first step towards optimization of CT doses in the Indian context.

    In light of the increased incidence of contact lens associated Acanthamoeba keratitis in recent years, this study analyzed longitudinal trends of its incidence among predominantly non-contact lens wearers in a high-volume referral center in South India. A retrospective analysis of microbiology laboratory records at the Aravind Eye Hospital from 1988-2009 was performed. The Maximum Excess Events Test (MEET) was used to identify epidemics of Acanthamoeba keratitis. There were a total of 38,529 unique cases of infectious keratitis evaluated over this time period, of which 372 were culture-positive for Acanthamoeba. Only three cases (0.9%) of Acanthamoeba keratitis occurred among contact lens wearers. MEET identified unique Acanthamoeba keratitis epidemics in 1993 and 2002. Discrete epidemics of Acanthamoeba keratitis occurred among a rural, non-contact lens wearing, population in South India in 1993 and 2002.

    In Tiruppur, 729 textile dyeing units are under operation and these units generate 96.1 MLD of wastewater. The untreated effluent was discharged into the Noyyal River till 1997. After the issuance of directions by Tamil Nadu Pollution Control Board (TNPCB) in 1997, these units have installed 8 common effluent treatment plants (CETP) consisting of physical, chemical and biological treatment units. Some of the units have installed individual ETP (IETP). The treated effluent was finally discharged into the river. The dyeing units use sodium chloride in the dyeing process for efficient fixing of dye in the fabric efficiently. This contributes high total dissolved solids (TDS) and chlorides in the effluent. CETPs and IETPs failed to meet discharge standards of TDS and chlorides and thereby significantly affected the river water quality. TDS level in the river water was in the range of 900 - 6600 mg/L, and chloride was in the range of 230 - 2700 mg/L. Orathupalayam dam is located across Noyyal river at 32 km down stream of Tiruppur. The pollutants carried by the river were accumulated in the dam. TDS in the dam water was in the range of 4250 - 7900 mg/L and chloride was in the range of 1600 - 2700 mg/L. The dam sediments contain heavy metals of chromium, copper, zinc and lead. In 2006, the High Court has directed the dyeing units to install zero liquid discharge (ZLD) plant and to stop discharging of effluent into the river. Accordingly, the industries have installed and commissioned the ZLD plant consisting of RO plant and reject management system in 2010. The effluent after secondary treatment from the CETP is further treated in RO plant. The RO permeate is reused by the member units. The RO reject is concentrated in multiple effect evaporator (MEE)/ mechanical vacuum re-compressor (MVR). The concentrate is crystallized and centrifuged to recover salt. The salt recovered is reused. The liquid separated from the centrifuge is sent to solar evaporation pan. The salt

    To screen the antimicrobial potential of three ethnomedicinal plants Chassalia curviflora Thw. (C. curviflora), Cyclea peltata Hook. F. & Thomson (C. peltata) and Euphorbia hirta L (E. hirta) used in folk medicines in Aarukani hills Kani tribe, Tamil Nadu, India against human bacterial pathogens. Antibacterial efficacy was performed by disc diffusion method against the pathogens viz., Escherichia coli (E. coli) (ATCC 35218), Staphylococcus aureus (S. aureus) (ATCC 6538), Salmonella typhi (S. typhi) (MTCC 733), Proteus vulgaris (P. vulgaris), Proteus mirabilis (P. mirabilis) and Streptococcus pyogenes (S. pyogenes) and incubated for 24 h at 37 °C. The maximum degree of antibacterial activity was observed in C. peltata followed by C. curviflora. While E. hirta showed comparatively low degree of antibacterial activity. The methanolic extract of C. peltata showed the antibacterial activity against three pathogens viz., S. pyogenes, P. vulgaris and E. coli with the inhibition zones 12 mm, 10 mm and 9 mm, respectively. hexane extracts of C. peltata also showed the antibacterial activity against two selected pathogens viz., P. vulgaris and P. mirabilis with 15 mm and 12 mm of inhibition zones. All the three different concentrations (0.25, 0.50 & 0.75 mg/mL) of methanolic extract of C. peltata show the inhibitory effect on the three susceptible bacteria S. pyogenes, P. vulgaris and E. coli with the maximum inhibition in the highest concentration (0.75 mg/mL). The methanolic and hexane extracts of C. curviflora exhibited the antibacterial activity against only one bacterium each i.e. P. vulgaris and S. typhi with the maximum zone of inhibition 13 and 11 mm respectively. The methanolic and hexane extracts of E. hirta exhibited the antibacterial activity against only one bacterium i.e. S. pyogenes with the maximum zone of inhibition 13 and 11 mm respectively. The present investigation revealed that the C. curviflora, C. peltata and E. hirta are potentially good source of

    The rate of influenza vaccination is low for children in India. The purpose of this study is to assess parental attitudes towards influenza vaccination in South India. Participants were parents who brought their children to the Well Baby Clinic of Christian Medical College Hospital, Vellore, India for routine immunization. Participants answered questions by written survey while waiting for their children's vaccination. A total of 456 surveys were completed (403 parents did not opt for trivalent influenza vaccination and 53 opted for influenza vaccination). The majority (53.60%) of those parents who did not accept influenza vaccination identified the lack of a doctor's recommendation as the main reason. When asked separately, many non-acceptors (44.91%) indicated that they did not believe or were not sure that the influenza vaccine was effective. Nearly all non-acceptors (92.56%) stated that they would opt for influenza vaccination if a doctor recommended it. The most common reason that parents not opting for influenza vaccination for their children was the lack of recommendation by a doctor. The results of this study suggest that recommendation by a doctor is a more important factor than belief in efficacy, cost, or convenience in parental decision-making regarding childhood influenza vaccination in India, unlike the United States where parents are less likely to follow recommendations.

    Full Text Available The aim of this study was to determine hematological profile of sickle cell disease (SCD from Surat, South Gujarat, India. This prospective cross-sectional study was conducted in the Department of Pediatrics and Sickle Cell Anemia Laboratory, Faculty of Pathology, Government Medical College, Surat, India, between July 2009 and December 2010. Patients included in this study were in their steady state for a long period of time without any symptoms related to SCD or other diseases which could affect the hematological parameters. Venous blood of all patients was collected in ethylenediaminetetraacetic acid and hematological indices were measured. Thirty-three subjects homozygous in all were studied for their hematological parameters for sickle cell anemia. Moderate to severe anemia, low mean cell volume and high foetal hemoglobin dominate the hematological profile of SCD children.

    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

    The south west coast of Kanyakumari district in Tamil Nadu, India, is significantly affected by seawater intrusion and diffusion of pollutants into the aquifers due to unregulated beach placer mining and other anthropogenic activities. The present study investigates the vulnerability of the coastal aquifers using Geographic Information System (GIS)-based DRASTIC model. The seven DRASTIC parameters have been analyzed using the statistical equation of this model to demarcate the vulnerable zones for aquifer contamination. The vulnerability index map is prepared from the weighted spatial parameters, and an accounting of total index value ranged from 85 to 213. Based on the categorization of vulnerability classes, the high vulnerable zones are found near the beach placer mining areas between Manavalakurichi and Kodimanal coastal stretches. The aquifers associated with settlements and agricultural lands in the middle-eastern part have experienced high vulnerability due to contaminated water bodies. Similarly, the coastal areas of Thengapattinam and Manakudi estuary and around the South Tamaraikulam have also been falling under high vulnerability condition due to backwater and saltpan. In general, the nearshore region except the placer mining zone and the backwater has a moderately vulnerable condition, and the vulnerability index values range from 149 to180. Significantly, the northern and northeastern uplands and some parts of deposition zones in the middle-south coast have been identified as low to no vulnerable conditions. They are structurally controlled by various geological features such as charnockite, garnet biotite gneiss and granites, and sand dunes, respectively. The aquifer vulnerability assessment has been cross-verified by geochemical indicators such as total dissolved solids (TDS), Cl(-), HCO₃(-), and Cl(-)/HCO₃(-) ratio. The high ranges of TDS (1,842--3,736 mg/l) and Cl(-) (1,412--2,112 mg/l) values are well correlated with the observed high

    Full Text Available Background: Pemphigus is a common autoimmune blistering disorder in India. However, there are no population based surveys from India available to study the prevalence of this disease. Aims: To estimate the incidence of pemphigus in Thrissur district, Kerala, South India. Methods: Questionnaire based survey was conducted among the practicing dermatologists of Trichur district between 1 st January 2001 and 1 st January 2002 to determine the incidence of pemphigus in the district. Results: Ten cases of pemphigus vulgaris, one case of pemphigus erythematosus, and two cases of pemphigus foliacious were diagnosed during the study period in a population of 2.9 million in Thrissur district. The average age of pemphigus vulgaris patients was 58years in males [42 to 82 years] and 37 in females [25 to 57 years]. The average age of the two male pemphigus foliacious patients was 46 years [52 and 40 years] and the only pemphigus erythematosus patient was a 45 year-old female.Five cases of pemphigus vulgaris were investigated clinically histopathologically and by using direct immunofluorescence, while two were investigated clinically and histopathologically, two cases clinically, and one case clinically and with Tzanck smear. Two cases ofpemphigus foliacious were diagnosed with the aid of direct immunofluorescence and the only case of pemphigus erythematosus was diagnosed with the aid of direct immunofluorescence. Pemphigus vulgaris was common among females. The incidence of pemphigus in Thrissur district is 4.4 per million. Conclusions: This study indicates that the incidence of pemphigus in Thrissur district is high in comparison to the available studies from Germany, France, and the North African country Tunisia.

    2005-10-01

    The article notes some problems with the prepositional discourse of research ethics that is dominant in the West, and joins the call for an ethics-in-context approach in the human sciences. Using detailed examples from my fieldwork in South India to develop a narrative about ethical conflicts, I explore the problematics of informed consent, confidentiality and other concepts central to research ethics in the USA. The article underscores the inherent and practical risks associated with ethical universalism - applying 'universal' moral principles that have been constructed (that is, derived) in one cultural context and exporting them, without modifications, to another. The personal narrative includes my emotions in the field; they do moral work. The article draws theoretically from Bakhtin, Rabinow and feminist scholars of the Indian diaspora.

    Sometime this summer, an Indian spacecraft orbiting over the moon's far side will release a lander. The craft will ease to a soft landing just after lunar sunrise on an ancient, table-flat plain about 600 kilometers from the south pole. There, it will unleash a rover into territory never before explored at the surface. That's the ambitious vision for India's second voyage to the moon in a decade, due to launch in the coming weeks. If Chandrayaan-2 is successful, it will pave the way for even more ambitious Indian missions, such as landings on Mars and an asteroid, as well as a Venus probe. Lunar scientists have much at stake, too. Chandrayaan-2 will collect data on the moon's thin envelope of plasma, as well as isotopes such as helium-3, a potential fuel for future fusion energy reactors. And it will follow up on a stunning discovery by India's first lunar foray, which found water molecules on the moon in 2009.

    2001-04-01

    We have analyzed the pollen content of 51 surface soil samples collected in tropical evergreen and deciduous forests from the Western Ghats of South India sampled along a west to east gradient of decreasing rainfall (between 11 degrees 30-13 degrees 20'N and 75 degrees 30-76 degrees 30'E). Values of mean annual precipitation (Pann, mm/yr) have been calculated at each of the 51 sampling sites from a great number of meteorological stations in South India, using a method of data interpolation based on artificial neural network. Interpolated values at the pollen sites of Pann range from 1200 to 5555mm/yr, while mean temperature of the coldest month (MTCO) remains >15 degrees C and humidity factor (AET/PET, the actual evapotranspiration to potential evapotranspiration ratio) remains also included between 65 and 72%.Results are presented in the form of percentage pollen diagrams where samples are arranged according to increasing values of annual precipitation. They indicate that the climatic signal of rainfall is clearly evidenced by distinct pollen associations. Numerical analyses show that annual precipitation is an important parameter explaining the modern distribution of pollen taxa in this region. Pollen taxa markers of high rainfall (Pann >2500mm/yr) are Mallotus type, Elaeocarpus, Syzygium type, Olea dioica, Gnetum ula, and Hopea type, associated with Ixora type and Caryota. Pollen taxa markers of low rainfall (Pann <2500mm/yr) are Melastomataceae/Combretaceae, Maytenus type, Lagerstroemia and Grewia. The proportions of evergreen taxa and of arboreal taxa vary according to rainfall values. Indeed, when rainfall is <2500mm/yr, percentage of arboreal pollen (AP) is <50% and proportion of evergreen taxa is <20%. When rainfall exceeds 2500mm/yr, AP values average 70%, and proportion of evergreen taxa increases from 60 to 90%. Moreover, a good correlation between precipitation and proportion of evergreen taxa (0.85) presumes that precipitation can be estimated from

    To estimate the costs of treating corneal ulcers at a tertiary eye care center in south India from a patient perspective. A prospective cohort study design at a tertiary eye care center in south India. Each subject presenting with corneal ulcers to the center had a detailed clinical and laboratory workup including slit-lamp biomicroscopy, direct smear examination with appropriate stains, and cultures. Data on direct costs including costs of consultation, studies to confirm diagnosis, and treatment were collected at baseline and follow-up visits. We also collected indirect costs including travel, accommodation, food, and loss of wages of both the subject and accompanying persons. We recruited 498 consecutive cases for the study. The mean duration of onset of symptoms before presentation at the cornea service was 13.1 +/- 19.9 days. The mean follow-up duration was 34.8 +/- 28.2 days. The total overall cost for accessing and receiving care was 85.8 US dollars +/- 4.6 (95% confidence interval: 76.4 US dollars, 94.6). The mean total cost to diagnose and appropriately treat 1 case of keratitis such that the patient had vision better than 6/18 at final follow-up was 56.2 US dollars +/- 3.6 (95% confidence interval: 49.0 US dollars, 63.3). : The costs to the patient to receive appropriate care for corneal ulcers in this population are much higher than the average monthly wage for this population. There is an urgent need to devise strategies that may help reduce costs of care for corneal ulcers in this population.

    South Gujarat coast (India) is experiencing increased coastal inundation and erosion caused by sea-level rise affecting the population, infrastructure, and environment. The area falls under low elevation coastal zone (LEZ) and its topography of the area is also making coast highly susceptible to flooding, especially at high tides and during the rainy season. As part of studies on shoreline changes field trip carried on the coastal taluka's of South Gujarat coast i.e. Surat, Navsari and Valsad shows various temporal changes is taking place at coastal belt. There are ample of studies on coastal dynamics and impacts. The study focus on spatial temporal analysis shows the vulnerable zones covering various physical elements at risk. These coastal areas are attractive in nature for all kind of economic development and growth because of availability of the water & fertile land for house hold use, fishing and transportation. On the contrary, South Gujarat coast being tectonically active; makes this region high vulnerable for any kind of infrastructure development. The region had also witnessed loss of life and property, disruptions to transport & power and incidences of epidemics during the floods of 2006 in Surat. Coastal flooding would, under these scenarios, threaten region that are home of 370,000 approx (Census, 2011) people in seven coastal taluka's of Surat, Navsari and Valsad district. Among the people residing in the region, the most vulnerable communities are fishermen, farmer and industrial labours. The wide range of infrastructure such as roads, hospitals, schools, power plants, industries and port will also be at risk. Shoreline changes are inevitably changing the characteristics of south Gujarat coast; practices and policies should be put in place to mitigate the potentially adverse impacts on environment and human settlements. Key words: sea level rise, LEZ, vulnerable, erosion, inundation, spatial temporal analysis, landuse changes.

    Marginalization and stigmatization heighten the vulnerability of sexual minorities to inequitable mental health outcomes. There is a dearth of information regarding stigma and mental health among men who have sex with men (MSM) in India. We adapted Meyer's minority stress model to explore associations between stigma and depression among MSM in South India. The study objective was to examine the influence of sexual stigma, gender non-conformity stigma (GNS) and HIV-related stigma (HIV-S) on depression among MSM in South India. A cross-sectional survey was administered to MSM in urban (Chennai) (n=100) and semi-urban (Kumbakonam) (n=100) locations in Tamil Nadu. The majority of participants reported moderate/severe depression scores. Participants in Chennai reported significantly higher levels of GNS, social support and resilient coping, and lower levels of HIV-S and depression, than participants in Kumbakonam. Hierarchical block regression analyses were conducted to measure associations between independent (GNS, HIV-S), moderator (social support, resilient coping) and dependent (depression) variables. Sexual stigma was not included in regression analyses due to multicollinearity with GNS. The first regression analyses assessed associations between depression and stigma subtypes. In Chennai, perceived GNS was associated with depression; in Kumbakonam enacted/perceived GNS and vicarious HIV-S were associated with depression. In the moderation analyses, overall GNS and HIV-S scores (subtypes combined) accounted for a significant amount of variability in depression in both locations, although HIV-S was only a significant predictor in Kumbakonam. Social support and resilient coping were associated with lower depression but did not moderate the influence of HIV-S or GNS on depression. Differences in stigma, coping, social support and depression between locations highlight the salience of considering geographical context in stigma analyses. Associations between HIV-S and

    Banana bunchy top disease (BBTD) caused by Banana bunchy top virus (BBTV) is one of the most devastating diseases of banana and poses a serious threat for cultivars like Hill Banana (Syn: Virupakshi) and Grand Naine in India. In this study, we have cloned and sequenced the complete genome comprised of six DNA components of BBTV infecting Hill Banana grown in lower Pulney hills, Tamil Nadu State, India. The complete genome sequence of this hill banana isolate showed high degree of similarity with the corresponding sequences of BBTV isolates originating from Lucknow, Uttar Pradesh State, India, and from Fiji, Egypt, Pakistan, and Australia. In addition, sixteen coat protein (CP) and thirteen replicase genes (Rep) sequences of BBTV isolates collected from different banana growing states of India were cloned and sequenced. The replicase sequences of 13 isolates showed high degree of similarity with that of South Pacific group of BBTV isolates. However, the CP gene of BBTV isolates from Shervroy and Kodaikanal hills of Tamil Nadu showed higher amino acid sequence variability compared to other isolates. Another hill banana isolate from Meghalaya state had 23 nucleotide substitutions in the CP gene but the amino acid sequence was conserved. This is the first report of the characterization of a complete genome of BBTV occurring in the high altitudes of India. Our study revealed that the Indian BBTV isolates with distinct geographical origins belongs to the South Pacific group, except Shervroy and Kodaikanal hill isolates which neither belong to the South Pacific nor the Asian group.

    The relevance of the gut microbiota to human health is increasingly appreciated. The objective of this study was to compare the gut microbiota of a group of adult tribals with that of healthy adult villagers in Tamil Nadu, India. Faeces were collected from 10 healthy tribal adults (TAs) in the Jawadhi hills and from 10 healthy villagers [rural adults (RAs)] in Vellore district, Tamil Nadu. DNA was extracted, and 456 bp segments comprising hypervariable regions 3 and 4 of the 16S rRNA gene were amplified, barcoded and 454 sequenced. Totally 227,710 good-quality reads were analyzed. TAs consumed a millets-based diet, ate pork every day, and did not consume milk or milk products. RAs consumed a rice-based diet with meat intake once a week. In both groups, Firmicutes was the most abundant phylum, followed by Proteobacteria, Bacteroidetes and Actinobacteria. The median Firmicutes-to-Bacteroidetes ratio was 34.0 in TA and 92.9 in RA groups. Actinobacteria were significantly low in TA, possibly due to non-consumption of milk. Clostridium constituted the most abundant genus in both groups, but was significantly more abundant in TAs than RAs, while Streptococcus was significantly more abundant in RA (P<0.05). Analyses of genetic distance revealed that the microbiota were distinctly different between TA and RA, and principal component analysis using 550 distinct taxonomically identifiable sequences revealed a clear separation of microbiota composition in the two groups. Phylogenetic analysis of major microbiota indicated clustering of microbial groups at different major branch points for TAs and RAs. Phylum Firmicutes and genus Clostridium constituted the bulk of the faecal microbiota, while significant differences in composition between the groups were probably due to differences in diet and lifestyle.

  14. The North-South divide in snake bite envenomation in India

    2016-01-01

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

    2012-09-01

    To understand how rural and other groups of marginalized women define safe abortion; their perspectives and concerns regarding medical abortion (MA); and what factors affect their access to safe abortion. Focus group discussions were held with various groups of rural and marginalized women in Tamil Nadu to understand their perspectives and concerns on abortion, especially MA. Nearly a decade after mifepristone was approved for abortion in India, most study participants had never heard of MA. When they learned of the method, most preferred it over other methods of abortion. The women also had questions and concerns about the method and recommendations on how services should be provided. Their definition of a "safe abortion" included criteria beyond medical safety. They placed a high priority on "social safety," including confidentiality and privacy. In their view, factors affecting access to safe abortion and choice of provider included cost, assurance of secrecy, promptness of service provision, and absence of provider gatekeeping and provider-imposed conditions for receiving services. Women's preference for MA shows the potential of this technology to address the problem of unsafe abortion in India. Women need better access to information and services to realize this potential, however. Women's preferences regarding information dissemination and service provision need to be taken into account if policies and programs are to be truly responsive to the needs of marginalized women.

    Full Text Available Abstract Background Enterococci tend to be one of the leading causes of nosocomial infections, with E. faecalis and E. faecium accounting up to 90% of the clinical isolates. Nevertheless, the incidence of other species of enterococci from clinical sources shows an alarming increase with the properties of intrinsic resistance to several antibiotics including beta-lactams and glycopeptides. Thus proper identification of enterococci to species level is quintessential for management and prevention of these bacteria in any healthcare facility. Hence this work was undertaken to study the prevalence of unusual species of enterococci causing human infections, in a tertiary care hospital in South India. Methods The study was conducted in a tertiary care hospital in South India from July 2001 to June 2003. Isolates of enterococci were collected from various clinical specimens and speciated using extensive phenotypic and physiological tests. Antimicrobial susceptibility testing were performed and interpreted as per NCCLS guidelines. Whole cell protein (WCP fingerprinting of enterococci were done for species validation by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE and analyzed computationally. Results Our study showed the prevalence of unusual (non-faecalis and non-faecium enterococci and atypical (biochemical variant species of enterococci as 19% (46 isolates and 5% (12 isolates respectively. The 7 unusual species (46 isolates isolated and confirmed by phenotypic characterization includes: 15 E. gallinarum (6.2%, 10 E. avium (4.1%, 6 E. raffinosus (2.5%, 6 E. hirae (2.5%, 4 E. mundtii (1.7%, 3 E. casseliflavus-including the two atypical isolates (1.2% and 2 E. durans (0.8%. The 12 atypical enterococcal species (5% that showed aberrant sugar reactions in conventional phenotyping were confirmed as E. faecalis, E. faecium and E. casseliflavus respectively by WCP fingerprinting. The antimicrobial susceptibility testing depicted the

    The geriatric health problems are related to chronic disease as a result of increasing life expectancy. This study was undertaken to assess the health problems of the elderly in Puducherry. This cross-sectional study was carried out on 214 elderly persons from the age group of 60 years and above using a pre-designed and pre-tested questionnaire that addressed the disease magnitude in comparison with the socioeconomic variables. Overall, 43% of the participants were diabetic, 47.7% hypertensive, 86% anemic and 68.2% visually impaired. All the morbidities were noted to be higher in the 70-79 years age group. Diabetes was significantly higher in participants from urban areas, with family history and increasing waist-hip ratio, but significantly lower in the below poverty line areas. Hypertension risk was significantly higher among females, among those leading sedentary life, those eating vegetarian food, those addicted to tobacco and with abdominal obesity. Anemia was significantly lower among urban vegetarians. Overweight and obese were noted in 31% of the participants, and were higher in females (87.5%). Rural residence, female sex, living in joint family, literacy, sedentary life style, decreasing per capita income and decreasing body mass index (BMI) were significantly associated with visual impairment. This study highlights the burden of health problems of elderly individuals in South India.

    The Raman lidar PollyXT has participated in two long-term aerosol experimental campaigns, one close to New Delhi in India (March 2008 - March 2009) and one at Elandsfontein about 150 km from Johannesburg in South Africa (December 2009 - January 2011). Since November 2012, the lidar has performed measurement at Kuopio, Finland. PollyXT is operated automated and continuous for 24/7 observations of clouds and aerosols. The observations are processed in near-real time without manual intervention, and are presented online at http://polly.tropos.de. The three measurement sites cover a wide range of pure aerosol types (biomass burning, volcanic ash, urban, desert dust, rural aerosols); as well as a mixture of these aerosol types. We retrieve the vertical profiles of the aerosol optical properties, i.e. extinction and backscatter coefficients, Ångström exponents, lidar ratio and depolarization ratio. We also study the seasonal variability of the intensive and extensive aerosol properties. Our results reveal typical and extraordinary aerosol conditions as well as seasonal differences at the three observational sites.

    Several studies have suggested a beneficial effect of infant breastfeeding on childhood cognitive function. The main objective was to examine whether duration of breastfeeding and age at introduction of complementary foods are related to cognitive performance in 9- to 10-year-old school-aged children in South India. The authors examined 514 children from the Mysore Parthenon birth cohort for whom breastfeeding duration (six categories from or = 18 months) and age at introduction of complementary foods (four categories from or = 6 months) were collected at the first-, second- and third-year annual follow-up visits. Their cognitive function was assessed at a mean age of 9.7 years using three core tests from the Kaufman Assessment Battery for children and additional tests measuring long-term retrieval/storage, attention and concentration, visuo-spatial and verbal abilities. All the children were initially breastfed. The mode for duration of breastfeeding was 12-17 months (45.7%) and for age at introduction of complementary foods 4 months (37.1%). There were no associations between longer duration of breastfeeding, or age of introduction of complementary foods, and cognitive function at 9-10 years, either unadjusted or after adjustment for age, sex, gestation, birth size, maternal age, parity, socio-economic status, parents' attained schooling and rural/urban residence. Within this cohort, in which prolonged breastfeeding was the norm (90% breastfed > or = 6 months and 65% breastfed for > or = 12 months), there was no evidence suggesting a beneficial effect of longer duration of breastfeeding on later cognitive ability.

    Full Text Available The present study reviews geomorphic changes and sediment characteristics in the Vellar river and the M.G.R. island in the Cuddalore District, of Tamilnadu, India, caused by the 26th December, 2004 Indian Ocean Tsunami. The island has an area of about 12,000 m2 and it is separated from the mainland by a channel. It is bounded to the east by the Vellar River and to the north and south by the Muzhukkuthurai lagoon. A vegetated coastal dune with a length of about 1.5 km protected the island. Tsunami waves ranging in height from 4 to 6 meters breached the dunes, caused erosion and carried debris of destroyed coastal buildings westward to more than 50 m inland. The tsunami run up was up to 1.3 m. Very fine sand with a thickness of one meter filled the Muzhukkuthurai lagoon in the west. Heavy erosion resulted in a steep beach gradient. Sediments transported from the SE and the SSE direction resulted in greater accretion along the intertidal region. The sediment layer exhibited trampled and load structures, indicating deposition by the flooding and receding motion of the water, moving at high velocity. The sediments ranged from fine to medium in size and were well sorted.

    Periodontal diseases are among the most prevalent oral diseases in the world. Apart from repercussions in the oral cavity, there is evidence that periodontitis contributes to systemic damage in chronic diseases such as cardiovascular disease, diabetes, and preterm low birth weight. The aims of this study were to estimate the prevalence of chronic periodontitis in a sample urban population (<18 years) in Tamil Nadu and to estimate the inflammatory burden posed by chronic periodontitis by calculating the periodontal inflammatory surface area. This was a population-based study and cross-sectional design. A total of 1000 individuals (<18 years) were selected and screened for their periodontal status, oral hygiene status (OHI), and the periodontal inflamed surface area (PISA) in an outreach center located in Chennai, India. The proportion of individuals with different periodontal states (health, gingivitis, and periodontitis) was determined. A multivariate logistic regression analysis was performed to assess the influence of the individual risk factors such as habits (tobacco use), systemic conditions (diabetes), and oral hygiene maintenance on periodontitis prevalence in the sample population. A high prevalence of periodontal disease was observed in the study population (42.3%). Among the urban participants, age, cigarette smoking, pan chewing, decayed, missing, and filled teeth scores, OHI scores, and PISA scores were found to be significantly associated with periodontitis (P < 0.05). Periodontitis prevalence appears to be high even in areas with adequate access to oral health care and an inflammatory burden risk exists in a definitive manner.

    The study examined relationships among meteorological parameters, water quality and diarrheal disease counts in two urban and three rural sites in Tamil Nadu, India. Disease surveillance was conducted between August 2010 and March 2012; concurrently water samples from street-level taps in piped distribution systems and from household storage containers were tested for pH, nitrate, total dissolved solids, and total and fecal coliforms. Methodological advances in data collection (concurrent prospective disease surveillance and environmental monitoring) and analysis (preserving temporality within the data through time series analysis) were used to quantify independent effects of meteorological conditions and water quality on diarrheal risk. The utility of a local calendar in communicating seasonality is also presented. Piped distribution systems in the study area showed high seasonal fluctuations in water quality. Higher ambient temperature decreased and higher rainfall increased diarrheal risk with temperature being the predominant factor in urban and rainfall in rural sites. Associations with microbial contamination were inconsistent; however, disease risk in the urban sites increased with higher median household total coliform concentrations. Understanding seasonal patterns in health outcomes and their temporal links to environmental exposures may lead to improvements in prospective environmental and disease surveillance tailored to addressing public health problems.

    This article scrutinizes the boiling of water in Tamil Nadu and Puducherry, India. Boiling, as it is commonly practiced, improves water quality, but its full potential is not being realized. Thus, the objective is to refine the method in practice, promote acceptability, and foster the scalability of boiling and household water treatment (HWT) writ large. The study is based on bacteriological samples from 300 households and 80 public standposts, 14 focus group discussions (FGDs), and 74 household interviews. Collectively, the data fashion both an empirical and ethnographic understanding of boiling. The rate and efficacy of boiling, barriers to and caveats of its adoption, and recommendations for augmenting its practice are detailed. While boiling is scientifically proven to eliminate bacteria, data demonstrate that pragmatics inhibit their total destruction. Furthermore, data and the literature indicate that a range of cultural, economic, and ancillary health factors challenge the uptake of boiling. Fieldwork and resultant knowledge arrive at strategies for overcoming these impediments. The article concludes with recommendations for selecting, introducing, and scaling up HWT mechanisms. A place-based approach that can be sustained over the long-term is espoused, and prolonged exposure by the interveners coupled with meaningful participation of the target population is essential.

    Full Text Available Abstract 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.

    This paper describes the introduction and development of intelligence testing in British India. Between 1919 and 1940 experimenters such as C. Herbert Rice, Prasanta Chandra Mahalanobis, and Venkatrao Vithal Kamat imported a number of intelligence tests, adapting them to suit a variety of South Asian languages and contexts. Charting South Asian psychometry's gradual move from American missionary efforts toward the state, this paper argues that political reforms in the 1920s and 1930s affected how psychometry was "indigenized" in South Asia. Describing how approaches to race and caste shifted across instruments and over time, this paper charts the gradual recession, within South Asian psychometry, of a "race" theory of caste. Describing some of the ways in which this "late colonial" period affected the postcolonial landscape, the paper concludes by suggesting potential lines for further inquiry into the later career of intelligence testing in India and Pakistan. © 2014 Wiley Periodicals, Inc.

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

One hundred and eighty farmers who had adopted crop insurance schemes were selected through random sampling procedure. The respondents were interviewed using a pre-tested questionnaire for identifying factors influencing and constraints in adoption of crop insurance schemes. The study revealed that lack of scope for crop diversification and definite crop loss due to adverse climatic condition were the major factors influencing the adoption of crop insurance schemes. The study inferred that lack of compensation from the crop insurance scheme, delayed payment of indemnity, lack of awareness about the scheme and lengthy procedure to avail crop insurance were the major constraints.

    Groundwater recharge and available groundwater resources in Chithar River basin, Tamil Nadu, India spread over an area of 1,722 km(2) have been estimated by considering various hydrological, geological, and hydrogeological parameters, such as rainfall infiltration, drainage, geomorphic units, land use, rock types, depth of weathered and fractured zones, nature of soil, water level fluctuation, saturated thickness of aquifer, and groundwater abstraction. The digital ground elevation models indicate that the regional slope of the basin is towards east. The Proterozoic (Post-Archaean) basement of the study area consists of quartzite, calc-granulite, crystalline limestone, charnockite, and biotite gneiss with or without garnet. Three major soil types were identified namely, black cotton, deep red, and red sandy soils. The rainfall intensity gradually decreases from west to east. Groundwater occurs under water table conditions in the weathered zone and fluctuates between 0 and 25 m. The water table gains maximum during January after northeast monsoon and attains low during October. Groundwater abstraction for domestic/stock and irrigational needs in Chithar River basin has been estimated as 148.84 MCM (million m(3)). Groundwater recharge due to monsoon rainfall infiltration has been estimated as 170.05 MCM based on the water level rise during monsoon period. It is also estimated as 173.9 MCM using rainfall infiltration factor. An amount of 53.8 MCM of water is contributed to groundwater from surface water bodies. Recharge of groundwater due to return flow from irrigation has been computed as 147.6 MCM. The static groundwater reserve in Chithar River basin is estimated as 466.66 MCM and the dynamic reserve is about 187.7 MCM. In the present scenario, the aquifer is under safe condition for extraction of groundwater for domestic and irrigation purposes. If the existing water bodies are maintained properly, the extraction rate can be increased in future about 10% to 15%.

Aims: The aims of this study were to estimate the prevalence of chronic periodontitis in a sample urban population (<18 years in Tamil Nadu and to estimate the inflammatory burden posed by chronic periodontitis by calculating the periodontal inflammatory surface area. Settings and Design: This was a population-based study and cross-sectional design. Subjects and Methods: A total of 1000 individuals (<18 years were selected and screened for their periodontal status, oral hygiene status (OHI, and the periodontal inflamed surface area (PISA in an outreach center located in Chennai, India. Statistical Analysis Used: The proportion of individuals with different periodontal states (health, gingivitis, and periodontitis was determined. A multivariate logistic regression analysis was performed to assess the influence of the individual risk factors such as habits (tobacco use, systemic conditions (diabetes, and oral hygiene maintenance on periodontitis prevalence in the sample population. Results: A high prevalence of periodontal disease was observed in the study population (42.3%. Among the urban participants, age, cigarette smoking, pan chewing, decayed, missing, and filled teeth scores, OHI scores, and PISA scores were found to be significantly associated with periodontitis (P < 0.05. Conclusions: Periodontitis prevalence appears to be high even in areas with adequate access to oral health care and an inflammatory burden risk exists in a definitive manner.

    South and Southeast Asia endure high vegetable production losses due to begomovirus diseases mainly transmitted by the insect vector, whitefly (Bemisia tabaci). Control over the spread of virus infection can be achieved through a better understanding of genetic diversity among B. tabaci. A total of 64 populations of B. tabaci collected from Tamil Nadu (India), Vietnam, Thailand, and Indonesia were investigated based on mitochondrial cytochrome c oxidase I (coxI) sequences. Populations from Tamil Nadu are distributed into three clades (Asia I, Asia II 7, and Asia II 8), whereas Indonesian populations settle along with Asia I population of India in the phylogenetic tree. Vietnam populations align with the Middle East-Asia Minor 1 (MEAM1) clade, and interestingly MEAM1 invades northern Vietnam quite recently. Samples from Thailand made a unique clade between the outgroup and the remaining B. tabaci, representing the possibility of a new subspecies. AMOVA analysis among populations from various districts in Tamil Nadu exhibits significant differences, which represent each district's individuality. This study proves that the use of coxI as a marker for molecular identification of B. tabaci can provide a better estimate of diversity. We provide important clues for developing insight into the genetic structure of B. tabaci, and suggest strategies for control.

    The outbreak of chikungunya fever that surfaced in India during late 2005 has affected more than 1.56 million people, spread to more than 17 states/union territories, and is still ongoing. Many of these areas are dengue- and leptospirosis-endemic settings. We carried out a cross-sectional survey in one such chikungunya-affected location in Dakshina Kannada District of Karnataka State to estimate the magnitude of the epidemic and the proportion of chikungunya virus (CHIKV) infections that remained clinically inapparent. The seropositivity for CHIKV infection was 62.2%, and the attack rate of confirmed CHIK fever was 58.3%. The proportion of inapparent CHIKV infection was 6.3%. The increasing trend in the seropositivity and attack rate of CHIKV infection with age group was statistically significant. The present study is an indicator of the magnitude of the ongoing outbreak of CHIKV infection in India that started during 2005-2006.

    Heavy metals and microbiological contamination were investigated in groundwater in the industrial and coastal city of Thoothukudi. The main sources of drinking water in this area are water bores which are dug up to the depth of 10-50 m in almost every house. A number of chemical and pharmaceutical industries have been established since past three decades. Effluents from these industries are reportedly being directly discharged onto surrounding land, irrigation fields and surface water bodies forming point and non-point sources of contamination for groundwater in the study area. The study consists of the determination of physico-chemical properties, trace metals, heavy metals and microbiological quality of drinking water. Heavy metals were analysed using Inductively Coupled Plasma Mass Spectrometry and compared with the (WHO in Guidelines for drinking water quality, 2004) standards. The organic contamination was detected in terms of most probable number (MPN) test in order to find out faecal coliforms that were identified through biochemical tests. A comparison of the results of groundwater samples with WHO guidelines reveals that most of the groundwater samples are heavily contaminated with heavy metals like arsenic, selenium, lead, boron, aluminium, iron and vanadium. The selenium level was higher than 0.01 mg/l in 82 % of the study area and the arsenic concentration exceeded 0.01 mg/l in 42 % of the area. The results reveal that heavy metal contamination in the area is mainly due to the discharge of effluents from copper industries, alkali chemical industry, fertiliser industry, thermal power plant and sea food industries. The results showed that there are pollutions for the groundwater, and the total Coliform means values ranged from 0.6-145 MPN ml-1, faecal Coliform ranged from 2.2-143 MPN ml-1, Escherichia coli ranged from 0.9 to 40 MPN ml-1 and faecal streptococci ranged from 10-9.20 × 102 CFU ml-1. The coastal regions are highly contaminated with total coliform bacteria, faecal coliform bacteria and E. coli. This might be due to the mixing of sewage from Thoothukudi town through the Buckle channel and fishing activity.

  6. Determinants of condom uptake among HIV voluntary counselling and testing clients: experiences from a hospital-based study in south India

    Science.gov (United States)

    2012-01-01

    Background HIV voluntary counselling and testing was a key HIV prevention strategy brought to scale by India's National AIDS Control Organization. Condom uptake is an essential metric of intervention impact given the expansion of the epidemic into an increasingly diverse population. With only 20% of first-time counselling and testing clients at the largest HIV treatment hospital in south India reporting previous condom use, the question of intervention impact on condom use deserves investigation. In this study, we track intervention impact across various demographic groups and identify the added value of more thorough counselling. Methods Data were collected from 8,865 individuals who attended counselling multiple times at the Tamil Nadu Government Hospital of Thoracic Medicine over the years 2004-2009. Counsellors recorded client demographic characteristics, HIV risk behaviours reported, and counselling services provided after each counselling session. Matching and regression methods were used to determine the probability of condom uptake by serostatus, gender, and receipt of personalized risk reduction counselling while controlling for other characteristics. Results HIV counselling and testing was associated with condom uptake among 29.2% of HIV positive women (CI 24.5-34.4%), 31.7% of HIV positive men (CI 27.8-35.4%), 15.5% of HIV negative women (CI 11.2-20.8%), and only 3.6% of HIV negative men (CI 1.9-5.9%) who had previously never used condoms. Personalized risk reduction counselling increased impact in some groups; for example an additional 18% of HIV negative women (CI 11.3-24.4%) and 17% of HIV positive men (CI 10.9-23.4%) started using condoms. The number of sexual partners was not associated with the impact of counselling completeness. Conclusions Because the components of testing and counselling impact the condom use habits of men and women differently, understanding the dynamics of condom use negotiation between partners is essential to optimizing

  7. India's Approach to Climate Negotiations. From the South to the North?

    2015-09-01

    India's approach to climate negotiations results from the interplay of two distinct logics, an external one and an internal one. While the external logic is derived from quantitative attributes at the aggregate level, such as the overall size of India's economy, the internal logic is derived from qualitative attributes at the individual level such as per person incomes and productivity. For three decades, from the early 1970's to the early 2000's, India's internal and external logics overlapped. India saw the global environmental issue as a struggle of the poor against the rich with itself at the forefront, and it strongly opposed any binding mitigation commitment. The endurance of this position rested on the fact that it was consistent with India's traditional bargaining positioning as leader of the developing world in north-south negotiations, which reflected a mixture of domestic pressure and a preference for a certain world order that favoured the poor. This changed as the size of India's economy grew to match that of large powerful countries. Indeed, by the early 2000's, there was widespread belief that India was on its way to become a 'rising power' and the Indian leadership sought to re-frame its climate position to suit the new label. From then on, India sought to have a more constructive approach and began a shift toward some form of mitigation commitment. In other words, the signals from India on climate policy positions tended to betray a tilt in favour of its foreign policy positions or its 'external logic'. This however led to a growing contradiction with the internal logic, and hence, to a persistent dilemma in India's negotiating posture. But of the two conflicting logics, the internal one is likely to overcome the external one. Immediate concerns such as poverty alleviation, development and the need for economic growth are seen to be more important than the contribution to global

    Full Text Available Purpose: To study the clinical presentation and treatment outcome of patients with ocular cysticercosis in southern India. Methods: This study included 10 patients who were diagnosed to have ocular or adnexal cysticercosis over a period of one year in Pondicherry, India. The clinical presentation, results of investigation and treatment outcome of the cases were analysed retrospectively. Results: Age of these patients ranged from 12 to 55 years. Four presented with loss of vision, two with a swelling in the eyelid, one with proptosis, one with diplopia and two with conjunctival involvement. ELISA for cysticercus antibodies in serum was positive in all cases. Albendazole and prednisolone were given for the treatment of these cases. Two patients responded well to treatment and were completely cured of the disease. There was partial improvement in 6 cases. Surgery in the form of excision was performed in two cases following a course of medical therapy. There was no significant change in visual acuity in eyes with intraocular cysticercosis following treatment. Conclusion: Ultrasonography B scan and ELISA for anticysticercal antibodies help to establish the diagnosis of ocular cysticercosis. A combination of oral albendazole and corticosteroids is found to be effective in confirmed cases. Intraocular cysticercosis is associated with a poor prognosis for vision.

    To report trends in antibiotic resistance in cases of bacterial keratitis from a large eye hospital in South India. In this retrospective cross-sectional study, the microbiology laboratory records of patients with infectious keratitis diagnosed at an eye hospital in South India from 2002 to 2013 were reviewed to determine the proportion with antibiotic non-susceptibility. 3685 bacterial isolates had susceptibility testing performed over the 12-year period. The two most common organisms with resistance were Streptococcus pneumoniae (n=1204) and Pseudomonas aeruginosa (n=894). Antibiotic non-susceptibility was generally uncommon for these two organisms and no significant trends were detected over the course of the study. In contrast, Staphylococcus aureus (N=211) isolates demonstrated a significant increase in fluoroquinolone non-susceptibility over the 12-year study period. This coincided with a significant increase in methicillin-resistant S. aureus (MRSA) during the study period, though the increase in fluoroquinolone resistance was likewise seen in methicillin-sensitive S. aureus (MSSA). For example, ofloxacin resistance in MSSA increased from 11.1% in 2002 to 66.7% in 2013 (p=0.002). No trends were apparent for the aminoglycosides, cefazolin or vancomycin, for which in vitro non-susceptibility generally appeared to be low. Resistance to antibiotics was generally stable for infectious keratitis isolates from a large eye hospital in South India, except for S. aureus, which experienced a significant increase in fluoroquinolone resistance from 2002 to 2013. Fluoroquinolone antibiotics currently have poor in vitro activity against both MRSA and MSSA in South India and are therefore not the ideal therapy for Staphylococcal corneal ulcers.

  18. Work and empowerment: women and agriculture in South India.

    Science.gov (United States)

    Rao, Smriti

    2011-01-01

    This article explores the implications of women's work in agriculture in Telangana, a region in the state of Andhra Pradesh, India. I suggest that higher capital costs for cultivators' post-liberalisation increased the pressure to contain wage costs in a region where women form the majority of the agricultural wage labour force. Under such conditions, when women perform both own-cultivation as well as agricultural wage work in the fields of others, they face pressure to restrict bargaining for higher wages, contributing to a widening gender wage gap. To the extent that wages shape intra-household bargaining power, the empowering effect of workforce participation for such women would thus be blunted. From available NSS data I provide some preliminary evidence in support of this argument.

    Full Text Available Background: Awareness of occupational hazards and its safety precautions among welders is an important health issue, especially in developing countries. Objective: To assess the awareness of occupational hazards and utilization of safety measures among welders in coastal South India. Methods: A cross-sectional study was conducted among 209 welders in Puducherry, South India. Baseline characteristics, awareness of health hazards, safety measures and their availability to and utilization by the participants were assessed using a pre-tested structured questionnaire. Results: The majority of studied welders aged between 20 and 40 years (n=160, 76.6% and had 1-10 years of education (n=181, 86.6%. They were more aware of hazards (n=174, 83.3% than safety measures (n=134, 64.1%. The majority of studied welders utilized at least one protective measure in the preceding week (n=200, 95.7%. Many of them had more than 5 years of experience (n=175, 83.7%, however, only 20% of them had institutional training (n=40, 19.1%. Age group, education level, and utilization of safety measures were significantly associated with awareness of hazards in univariate analysis (p<0.05. Conclusion: Awareness of occupational hazards and utilization of safety measures is low among welders in coastal South India, which highlights the importance of strengthening safety regulatory services towards this group of workers.

    Birth weight centile curves are commonly used as a screening tool and to assess the position of a newborn on a given reference distribution. Birth weight of twins are known to be less than those of comparable singletons and twin-specific birth weight centile curves are recommended for use. In this study, we aim to construct gestational age specific birth weight centile curves for twins born in south India. The study was conducted at the Christian Medical College, Vellore, south India. The birth records of all consecutive pregnancies resulting in twin births between 1991 and 2005 were reviewed. Only live twin births between 24 and 42 weeks of gestation were included. Birth weight centiles for gestational age were obtained using the methodology of generalized additive models for location, scale and shape (GAMLSS). Centiles curves were obtained separately for monochorionic and dichorionic twins. Of 1530 twin pregnancies delivered during the study period (1991-2005), 1304 were included in the analysis. The median gestational age at birth was 36 weeks (1st quartile 34, 3rd quartile 38 weeks). Smoothed percentile curves for birth weight by gestational age increased progressively till 38 weeks and levels off thereafter. Compared with dichorionic twins, monochorionic twins had lower birth weight for gestational age from after 27 weeks. We provide centile values of birth weight at 24 to 42 completed weeks of gestation for twins born in south India. These charts could be used both in routine clinical assessments and epidemiological studies.

    Evidence shows that women with disability have adverse pregnancy outcomes compared to those without a disability. There is a lack of published data on reproductive health of women with disability in India till date. The objective of the South India Disability Evidence (SIDE) Study was to compare reproductive health parameters including pregnancy experience, health access during pregnancy and type of delivery among women with disability compared to women with no disability. The study was conducted in one district each in two States (Andhra Pradesh and Karnataka) in 2012. A case-control design was used to identify appropriate age and sex-matched controls for women with disability identified through a population-based survey. Trained key informants first listed women with disabilities who were then examined by a medical team to confirm the diagnosis. Trained research investigators administered questionnaire schedules to both groups of women to collect information on reproductive health and outcomes of any pregnancy experienced in the past two years. A total of 247 women with disability and 324 age-matched controls aged 15-45 years were recruited for the study. 87% of the women with disability had a physical disability. The mean age of women with disability was 29.86 against 29.71 years among women without a disability. A significantly lower proportion of women with disability experienced pregnancy (36.8%) compared to women without a disability (X (2) -16.02 P India for the first time ever. The findings will help in formulating policy and to develop specific interventions to improve pregnancy outcomes for women with disability in India.

    Full Text Available The cost of pharmaceuticals, as a percentage of total healthcare spending, has been rising worldwide. This has resulted in strained national budgets and a high proportion of people without access to essential medications. Though India has become a global hub of generic drug manufacturing, the expected benefits of cheaper drugs are not translating into savings for ordinary people. This is in part due to the rise of branded generics, which are marketed at a price point close to the innovator brands. Unbranded generic medicines are not finding their way into prescriptions due to issues of confidence and perception, though they are proven to be much cheaper and comparable in efficacy to branded medicines. The drug inventory of unbranded generic manufacturers fares reasonably when reviewed using the World Health Organization-Health Action International (WHO-HAI tool for analysing drug availability. Also, unbranded generic medicines are much cheaper when compared to the most selling brands and they can bring down the treatment costs in primary care and family practice. We share our experience in running a community pharmacy for an urban health center in the Pathanamthitta district of Kerala State, which is run solely on generic medicines. The drug availability at the community pharmacy was 73.3% when analyzed using WHO-HAI tool and the savings for the final consumers were up to 93.1%, when compared with most-selling brand of the same formulation.

    2012-10-01

    Mercury is an element of growing global concern. The United Nations Environment Programme plans to finalise a new global legally binding instrument on mercury by 2013, to coordinate actions to reduce emissions of mercury. It has been well established that Asia represents not only the region contributing to greatest current mercury emissions but also the region with the fastest growth rate. Despite this, emissions from human activities in most countries in this region are not well characterised. This report summarises the limited data available on mercury emissions from India, Cambodia, Indonesia, Malaysia, the Philippines, Thailand and Vietnam. These countries were specifically selected as they are areas of potentially significant growth in energy use in the near future. Information is given on the major sources of mercury in these countries, concentrating mostly on coal combustion and the non-ferrous metal industry. Although it is beyond the scope of this report to make new estimates for emissions, information is provided on current fossil fuel use and industrial activity as well as projections for these sectors to 2020 to give an indication of the general scale of these sources and the potential for increased emissions in the future. Some countries have established regulations or action plans on emissions and these are summarised where possible. Recommendations are then made for potential actions which could be taken in each country to encourage action and achieve economic reduction in mercury emissions.

The frequency of herpes zoster amongst skin OPD cases was found to be 0.34 per cent. The male to female ratio was 1.74:1. The most common prodromal symptom seen was paresthesia in 25 (23.36% cases followed by itching in 21 (19.62% cases.Most common presenting complaint was pain in 97 (90.65% cases. Ninety nine cases had classical herpes zoster followed by necrotic / ulcerated herpes zoster in 5 cases and hemorrhagic herpes zoster in 3 cases. Thoracic dermatome was the most common dermatome involved in 64 (59.8% cases followed by cervical in 17 (15.8% cases. Unidermatomal involvement was seen in 81 (75.7% cases, followed by multidermatomal in 18 (16.8% cases and disseminated in 8 (7.4% cases. Forty six cases were screened for HIV, out of them; six cases (4 males, 2 females were seropositive for HIV. Classical herpes zoster was a feature in four cases; however, one case each also had necrotic and hemorrhagic form of herpes zoster. To conclude, herpes zoster commonly occurs in young adults in India with presenting symptoms such as pain, itching and fever.

    Of India's population, 76.6 million (7.2%) are aged above 60 years. Increasing age is associated with increasing disability and functional impairments such as low vision, loss of mobility and hearing impairment. Hence, the purpose of this paper is to study the prevalence of hearing and visual impairment among a rural elderly population in South India and its association with selected variables. This was a cross-sectional study of elderly persons in two villages of Bangalore District, Karnataka, South India. Elderly persons identified were administered a questionnaire for assessment of demographic details, health and function related information. Visual acuity was checked using Snellen's E chart for distant vision. Hearing was assessed using pure tone audiometry. Two hundred and fifty-seven (12.2%) of the population were elderly in these two villages. Seventy-two (32.4%) of the elderly persons were facing problems completely or partially in at least one of the activities and 10 (4.5%) elderly persons had cognitive impairment. Sixty-two (35.4%) of the elderly had low vision and 22 (12.6%) were blind. On assessment with pure tone audiometry, 117 (66.9%) of the elderly persons had some degree of hearing impairment. Forty-three (24.6%) of the elderly had disabling hearing impairment. Forty-seven (26.9%) of the elderly had combined low vision associated with hearing impairment and 18 (10.2%) had combined blindness along with hearing impairment. As age advanced there was a significant increase in visual, hearing and combined impairments. Visual and hearing impairment are important health problems among elderly persons in rural areas of South India. © 2011 Japan Geriatrics Society.

    After rifting from Gondwana in the Late Jurassic - Early Cretaceous, and subsequent opening of the Indian Ocean basin, the continental margins of India developed into typical passive margins. Extensional tectonic forces and thermal subsidence gave rise to the formation of both on-shore and off-shore basins along the southeastern passive margin of the Indian continent, along the Tamil Nadu coast. There, basins such as the Cauvery and Krishna-Godavari basin, accumulated Meso- and Cenozoic (Early Cretaceous to recent) detrital sediments coming off the rifted blocks and the Tamil Nadu hinterland. In places, deep rift basins have accumulated up to over 3000 m of sediments. The continental basement of Tamil Nadu is chiefly composed of metamorphic rocks of the Archean to Palaeoproterozoic Eastern Dharwar Craton and the coeval Southern Granulite Terrane (e.g. Peucat et al., 2013). Several crustal scale shear zones crosscut this assemblage and at least some are considered to represent Gondwanan sutures (Santosh et al., 2012). Smaller, younger granitoid plutons intrude the basement at several locations and most of these are of Late Neoproterozoic age (Glorie et al., 2014). In this work metamorphic basements rocks and the younger granitoids were sampled for a apatite fission-track (AFT) thermochronometric study. A North-South profile from Chennai to Thanjavur mainly transects the Salem block of the Southern Granulite Terrane, and crosscuts several crustal scale shear zones, such as the Cauvery, Salem-Attur and Gangavalli shear zones. Apatites from over 30 samples were used in this study. AFT ages all range between about 190 and 120 Ma (Jurassic - Early Cretaceous). These mainly represent the slow, shallow exhumation of the basement during the rift and early drift phase of the Indian plate from Gondwana. AFT mean track lengths vary between 11 and 13 µm and are typical of slowly exhumed basement. Thermal history modelling (using the QTQt software by Gallagher, 2012) confirms

    Full Text Available Among healthcare workers in developing countries, nurses spend a large amount of time in direct contact with tuberculosis (TB patients, and are at high risk for acquisition of TB infection and disease. To better understand the epidemiology of nosocomial TB among nurses, we recruited a cohort of young nursing trainees at Christian Medical College, a large, tertiary medical school hospital in Southern India.Among 535 nursing students enrolled in 2007, 468 gave consent to participate, and 436 underwent two-step tuberculin skin testing (TST. A majority (95% were females, and almost 80% were under 22 years of age. Detailed TB exposure information was obtained using interviews and clinical log books. Prevalence of latent TB infection (LTBI was estimated using Bayesian latent class analyses (LCA. Logistic regression analyses were done to determine the association between LTBI prevalence and TB exposure and risk factors. 219 of 436 students (50.2%, 95% CI: 45.4-55.0 were TST positive using the 10 mm or greater cut-off. Based on the LCA, the prevalence of LTBI was 47.8% (95% credible interval 17.8% to 65.6%. In the multivariate analysis, TST positivity was strongly associated with time spent in health care, after adjusting for age at entry into healthcare.Our study showed a high prevalence of LTBI even in young nursing trainees. With the recent TB infection control (TBIC policy guidance from the World Health Organization as the reference, Indian healthcare providers and the Indian Revised National TB Control Programme will need to implement TBIC interventions, and enhance capacity for TBIC at the country level. Young trainees and nurses, in particular, will need to be targeted for TBIC interventions.

    To investigate the demographic and obstetric profile of women seeking medical termination of pregnancy (MTP) in South India in accordance with the MTP Act of India. A registry-based retrospective study was carried out at a tertiary care teaching hospital in South India. The hospital records of all pregnant women seeking MTP over a 2-year period between January 2011 and December 2012 were reviewed. A total of 244 women underwent MTP during the study period. More than one-third (37.8%) were aged between 26 and 30 years. The majority of women underwent MTP during the first trimester (79.5%). Medical reasons were cited as the most common reason for undergoing MTP (39.3%), followed by unplanned pregnancy (34.8%). The majority of women were seeking MTP for the first time (84.8%). More than half of the women (52.9%) opted for post-MTP contraception. MTP for unplanned pregnancy can be prevented if people are well informed about methods of contraception. MTP is an opportunity for healthcare professionals to discuss fertility needs and need for contraception with women seeking MTP so that appropriate decisions can be taken for suitable family planning.

    Pulp and paper mills generate varieties of pollutants depending upon type of the pulping process being used. This paper presents the characteristics of wastewater from South India Paper Mill, Karnataka, India which is using recycled waste paper as a raw material. The raw wastewater consists of 80-90 mg L( - 1) suspended solid and 1,010-1,015 mg L( - 1) dissolved solid. However, pH varied from 5.5-6.8. The biochemical oxygen demand and chemical oxygen demand ranged from 200-210 and 1,120-1,160 mg L( - 1), respectively. Aerobic treatment of raw effluent attribute to significant reduction in suspended solid (range between 25 to 30 mg L( - 1)) and total dissolved solid (range between 360 to 390 mg L( - 1)). However, pH, temperature, and electrical conductivity were found superior after treatment. Copper, cadmium, iron, lead, nickel, and zinc were found in less quantity in raw effluent and were almost completely removed after treatment. The dendrogram of the effluent quality parameters clearly indicate that South India Paper Mill does not meet Minimal National Standard set by central Pollution Control Board to discharge in agricultural field.

    To report the prevalence and causes of unilateral visual impairment (UVI) in rural population of all ages in rural Andhra Pradesh, India. A population-based cross sectional study using a multi-stage cluster sampling methodology was carried out in West Godavari, Adilabad and Mahbubnagar districts in south India. A comprehensive eye examination that included presenting and best corrected visual acuity and dilated fundus examination was conducted by trained professionals. UVI is defined as presenting visual acuity visual impairment. The mean age of the participants was 27.4y (standard deviation: 17.9y), 51.9% were women and 49.1% were educated. The prevalence of UVI was 7.8% (95% CI: 7.2%-8.5%). Uncorrected refractive error (60.8%), cataract (17.4%) and retinal causes (6.6%) were the leading causes of UVI. On multiple logistic regression analyses, older age, not having education, living in well-off district had significantly higher odds of being associated with UVI. UVI was not associated with gender. UVI is common in rural south India. Most of it is due to cataract and refractive errors, both of which can be addressed at primary and secondary levels of eye care. Burden of UVI should also be considered in planning eye care services.

    The rising importance of the BASIC countries in a changing world Over the last decade the emerging economies have become increasingly important for the development of the global economy. This trend was reinforced by the global financial crisis which hit the developed economies the hardest, and after which the emerging economies emerged as crucial growth centres in the global economy. We are entering into a new era in global politics, and a broad process is currently taking place of restructuring global institutions and political processes to increasingly take into account the interests of the emerging economies. A global environmental crisis constitutes the backdrop for this change in global politics, as the current volume of production and consumption of the planets renewable resources (including the capacity to absorb greenhouse gas emissions) is beyond the planets regenerative capacity. The breakdown of the Doha Development Round in World Trade, the creation of the BRIC group and the G20, the emergence of the BASIC group of key emerging economies and the following developments under the UN Framework Convention on Climate Change, all testify to the fact that China, India, South Africa and Brazil (BASIC) today have a decisive and increasing influence in world politics. With regards to the environment, this means that BASIC countries increasingly will set environmental standards in global markets as their economies to a greater extent come to represent global buying power, increasingly will influence to what extent environmental concerns are mainstreamed into international agreements (such as WTO) in general, and also will decide the scope and level of ambition and scope of international environmental agreements (as we see in UNFCCC). Among the emerging economies China, India, South Africa, and Brazil stand out as particularly important. China and India alone represent more than 35 per cent of the global population and are the most rapidly growing economies in the

    This article presents the results of an assessment of gynecological morbidity among 385 women with young children residing in a district of Karnataka State, South India. All three main modes of assessment (clinical examination, laboratory tests, and self-reports) reveal a high burden of reproductive tract infections. The two most common conditions, identified by laboratory tests, were bacterial vaginosis and mucopurulent cervicitis. Approximately one-fourth of the women had clinical evidence of pelvic inflammatory disease, cervical ectopy, and fistula. The contribution of sexually transmitted diseases to overall gynecological morbidity appears to be relatively modest; 10 percent were so diagnosed. Associated conditions of anemia and chronic energy deficiency were common. Severe anemia was found in 17 percent of cases and severe chronic energy deficiency in 12 percent. These results indicate that radical improvements in women's health in India will require far more than the diagnosis and treatment of reproductive tract infections.

    Carbapenem resistance is disseminating worldwide among Gram-negative bacteria. The aim of this study was to identify carbapenem-resistance level and to determine the mechanism of carbapenem resistance among clinical isolates from two centres in Tamil Nadu. In the present study, a total of 93 Gram-negative isolates, which is found to be resistant to carbapenem by disk diffusion test in two centres, were included. All isolates are identified at species level by 16S rRNA sequencing. Minimal inhibitory concentrations (MICs) of isolates for Meropenem were tested by agar dilution method. Presence of blaOXA, blaNDM, blaVIM, blaIMP and blaKPC genes was tested by PCR in all isolates. Amplicons were sequenced for confirmation of the genes. Among 93 isolates, 48 (%52) were Escherichia coli, 10 (%11) Klebsiella pneumoniae, nine (%10) Pseudomonas aeruginosa. Minimal inhibitory concentration results showed that of 93 suspected carbapenem-resistant isolates, 27 had meropenem MICs ≥ 2 μg/ml. The MIC range, MIC50 and MIC90 were 128 μg/ml, 0.12 and 16 μg/ml, respectively. Fig. 1 . Among meropenem-resistant isolates, E. coli were the most common (9/48, 22%), followed by K. pneumoniae (7/9, 77%), P. aeruginosa (6/10, 60%), Acinetobacter baumannii (2/2, 100%), Enterobacter hormaechei (2/3, 67%) and one Providencia rettgeri (1/1, 100%). PCR results showed that 16 of 93 carried blaNDM, three oxa181, and one imp4. Among blaNDM carriers, nine were E. coli, four Klebsiella pneumoniae, two E. hormaechei and one P. rettgeri. Three K. pneumoniae were OXA-181 carriers. The only imp4 carrier was P. aeruginosa. A total of seven carbapenem-resistant isolates were negatives by PCR for the genes studied. All carbapenem-resistance gene-positive isolates had meropenem MICs >2 μg/ml. Our results confirm the dissemination of NDM and emergence of OXA-181 beta-lactamase among Gram-negative bacteria in South India. This study showed the emergence of NDM producer in clinical isolates of E

    Full Text Available Neurofibromatosis type 1 (NF-1 is the most common form of neurofibromatosis. Since the significance of various cutaneous manifestations of NF-1 has not been known in Indian population, hence, the present study was undertaken. A total of 40 patients with NF-1 were identified between August 1998 to June 2000 with a prevalence rate of 20.4 per 10,000 individuals attending our clinic. Male to female ratio was 2.3: 1. The age of the patients ranged from 15 to 70 years with a mean age of 29.57 years. Most patients (18 cases belonged to age group of 21-30 years followed by 11-20 years age group (11 cases. Twenty four cases had onset of disease between 11-20 years of age and ten cases in 21-30 years age group. Thirty one of 40 cases presented with asymptomatic nodules, three sought medical opinion for cosmetic reasons and another three for hyper pigmented patch. Analysis of cutaneous manifestations showed, 39 of 40 cases (97.5% had neurofibromas. Palmar melanotic macules were noted in 36 (90% cases whereas café â€" au-lait macules were seen in 33(82.5% cases. Subsequent, less common findings were intertriginous freckles in 31(77.5% cases, plantar melanotic macules in 18(45% cases and generalized freckles in 4(10% cases. Statistical analysis of cases and controls revealed significant association of NF-1 with neurofibromas, palmar melanotic macules, café-au-lait macules, intertriginous freckles and plantar melanotic macules(p<0.001. This study brings into focus some of the cutaneous manifestations noted in South Indian patients especially palmar and plantar melanotic macules, not highlighted in the western literature.

    Full Text Available Abstract Background Tuberculosis (TB incidence data in vaccine target populations, particularly adolescents, are important for designing and powering vaccine clinical trials. Little is known about the incidence of tuberculosis among adolescents in India. The objective of current study is to estimate the incidence of pulmonary tuberculosis (PTB disease among adolescents attending school in South India using two different surveillance methods (active and passive and to compare the incidence between the two groups. Methods The study was a prospective cohort study with a 2-year follow-up period. The study was conducted in Palamaner, Chittoor District of Andhra Pradesh, South India from February 2007 to July 2010. A random sampling procedure was used to select a subset of schools to enable approximately 8000 subjects to be available for randomization in the study. A stratified randomization procedure was used to assign the selected schools to either active or passive surveillance. Participants who met the criteria for being exposed to TB were referred to the diagnostic ward for pulmonary tuberculosis confirmation. A total number of 3441 males and 3202 females between the ages 11 and less than 18 years were enrolled into the study. Results Of the 3102 participants in the active surveillance group, four subjects were diagnosed with definite tuberculosis, four subjects with probable tuberculosis, and 71 subjects had non-tuberculous Mycobacteria (NTM isolated from their sputum. Of the 3541 participants in the passive surveillance group, four subjects were diagnosed with definite tuberculosis, two subjects with probable tuberculosis, and 48 subjects had non-tuberculosis Mycobacteria isolated from their sputum. The incidence of definite + probable TB was 147.60 / 100,000 person years in the active surveillance group and 87 / 100,000 person years in the passive surveillance group.

    Historical records indicate that the Portuguese brought the African Siddis to Goa, India, as slaves about 500 years ago. Subsequently, the Siddis moved into the interior regions of the state of Karnataka, India, and have remained there ever since. Over time the Siddis have experienced considerable cultural changes because of their proximity to neighboring population groups. To understand the biological consequences of these changes, we studied the Siddis to determine the extent of genetic variation and the contributions from the African, European, and Indian ancestral populations. In the present study we typed the Siddis for 20 polymorphic serological, red cell, and Alu insertion-deletion loci. The overall pattern of phenotype (and genotype) distribution is in accordance with Hardy-Weinberg expectations. Considering the ethnohistorical records and the availability of secondary-source genetic data, we used two data sets in the analysis: one comprising eight serological and red cell enzyme markers with eight population groups and another comprising six Alu insertion-deletion markers with seven tribal groups of South India. The dendrograms generated from these two data sets on the basis of genetic distance analysis between the selected populations of African, European, and Indian descent reveals that the Siddis are closer to the Africans than they are to the South Indian populations. Genetic admixture analysis using a dihybrid model (19 loci) and a trihybrid model (10 loci and 8 loci) shows that the predominant influence comes from the Africans, a lesser contribution from the South Indians, and a slight contribution from the Portuguese. Thus the original composition of the African genes among the Siddis has been diluted to some extent by the contribution from southern Indian population groups. There is no nonrandom association of alleles among a set of 10 genetic marker systems considered in the present study. The demonstration of genetic homogeneity of the Siddis

    Introduction In rapidly developing countries such as India, the ubiquity of air pollution sources in urban and rural communities often results in ambient and household exposures significantly in excess of health-based air quality guidelines. Few efforts, however, have been directed at establishing quantitative exposure–response relationships in such settings. We describe study protocols for The Tamil Nadu Air Pollution and Health Effects (TAPHE) study, which aims to examine the association between fine particulate matter (PM2.5) exposures and select maternal, child and adult health outcomes in integrated rural–urban cohorts. Methods and analyses The TAPHE study is organised into five component studies with participants drawn from a pregnant mother–child cohort and an adult cohort (n=1200 participants in each cohort). Exposures are assessed through serial measurements of 24–48 h PM2.5 area concentrations in household microenvironments together with ambient measurements and time-activity recalls, allowing exposure reconstructions. Generalised additive models will be developed to examine the association between PM2.5 exposures, maternal (birth weight), child (acute respiratory infections) and adult (chronic respiratory symptoms and lung function) health outcomes while adjusting for multiple covariates. In addition, exposure models are being developed to predict PM2.5 exposures in relation to household and community level variables as well as to explore inter-relationships between household concentrations of PM2.5 and air toxics. Finally, a bio-repository of peripheral and cord blood samples is being created to explore the role of gene–environment interactions in follow-up studies. Ethics and dissemination The study protocols have been approved by the Institutional Ethics Committee of Sri Ramachandra University, the host institution for the investigators in this study. Study results will be widely disseminated through peer-reviewed publications and

    With a high prevalence of diabetes in India, there is a need to study the impact of this disease on the quality of life (QoL) of the patients. This facility-based cross-sectional study assessed the QoL of patients attending the diabetic clinic using the World Health Organization (WHO) QoL BREF instrument in Tamil Nadu. The QoL was analyzed domain-wise and various socio-demographic factors affecting the QoL were studied. The mean total score of the QoL scale was 58.05 (95% CI, 22.18-93.88). Domain-wise, 63% had good physical, 69% had good psychological, 27% had good social and 85% had good environmental QoL scores. Males, currently married and those with BMI more than 25 had a statistically significantly better QoL compared to their counterparts. Diabetes does impair the QoL of patients but not to a great extent. There is a need to specifically target and improve the QoL of women, widowed and separated, and non-obese diabetics who are at risk of a poor QoL. QoL assessment should be routinely practiced in diabetic clinics.

Eighty-nine groundwater samples were collected during pre-monsoon (May) 2011 and were analyzed for major cations and anions. The irrigational parameters like; EC, Kelley's ratio, sodium absorption ratio (SAR) values, Mg(2+) hazards, HCO3 (-) and residual sodium carbonate (RSC) have been worked out to know the suitability of the groundwater for irrigational purpose. Wilcox diagram indicates that out of 89 samples, 39 samples belong to good permissible category and Doneen diagram revealed that 98.88 % of the groundwater samples fall in Class I. The plotting of SAR values in USSL diagram indicates that all the samples have low SAR value. Out of 89 samples, 44 samples were in C3-S1 field. This implies that no alkali hazard is anticipated to the crops. In 44 locations (49.44 %), samples fall within C3-S1 category. This category is suitable for irrigation purpose. However, the concentration of bicarbonate was in significant amount showing 82 % of sites under "increasing problem" and the 4 % sites under "Severe Problem" zones. Finally, the above-said results are taken into a Geographic Information System (GIS) platform. To understand the spatial distribution of unsuitable zones, ArcGIS was employed. The present work reveals that groundwater in the Omalur Taluk is of good quality and is suitable for all uses including interbrain water transfer in the region.

    Highlights: • Investigation on economic feasibility of PV/diesel system in various climatic zones. • HOMER is used to solve economic feasibility analysis. • By the sensitivity analysis, the net present cost is reduced. • Optimum climatic zone in Tamil Nadu, India is recommended. - Abstract: With the increasing threat to environment and the fast depleting fossil fuel resources, hybrid power systems consisting of two or more renewable energy sources such as solar PV, wind, biomass, ocean thermal-with or without the back up of diesel generator have come to the forefront. These hybrid systems are normally integrated with battery banks for total reliability; such systems have brought about better quality of life in remote areas of developing economics. The remote areas in the state of Tamil Nadu in India possess excellent renewable energy sources. These areas fall under different climatic zones, are sparsely populated and are in the process of development. Though these areas are connected to the grid, Tamil Nadu grid is not stable; it is currently experiencing 40% short fall in generation. Thus grid power is available to these remote areas only for 10 h a day and even when available, there are voltage frequency problems. This paper analyses the economic feasibility of installing and operating hybrid systems in these areas. The areas are divided into different climatic zones and the hybrid system economy is analyzed for each climatic zone on the basis of NPC (net present cost), consumption of diesel and renewable fraction for all climate zones. The analysis indicates that the interior climatic zone – the area would be the optimum climatic zone to install HPS PV/diesel. The sensitivity analysis proves that the NPC of such a system can be reduced. It is suggested that due to high initial cost, government subsidy is necessary to adopt the system on a large scale. Such a profit will encourage development of renewable energy utilization and bring about rapid

In addition to climate, the importance of the thickness and nature of the blanket of loose and transportable weathered material, namely regolith, which overlies the intact bedrocks, was also recently invoked, especially in tropical environment. We have conducted an integrated approach of the Critical Zone in two pristine forested small watersheds located in Cameroon and India. Both watersheds have developed on granito-gneissic bedrocks of stable Precambrian shields. Our approach is directed at (i) understanding the bio-geochemical, hydro-geological and hydrological processes and (ii) assessing the long-term and contemporary chemical weathering rates. The Nsimi watershed, South Cameroon, has been the first to be monitored since 1994. It belongs to the Nyong River basin and has a humid tropical climate. It is

    With the promotion of community-based rehabilitation (CBR) as a solution to health-related issues across the global South, leprosy colonies have long been out of vogue for nongovernmental organizations and State institutions alike. Such colonies, however, have endured. As is being increasingly recognized by those working in the leprosy field, such places have played a particular role not only in the provision of leprosy-related care but also in forging new and collective identities for people affected by leprosy that might otherwise not have been possible. In this article, I draw on ethnographic fieldwork in one such colony in coastal Andhra Pradesh, South India, and explore the values invested in it as a particular kind of place; its geographical location on the peripheries; and its architecture and layout (inspired in part by colonial sanatoriums), which have particular implications for how leprosy and its ramifications are constituted and managed.

    Local groundwater levels in South India are falling alarmingly. In the semi-arid crystalline Deccan plateau area, agricultural production relies on groundwater resources. Downscaled Global Climate Model (GCM) data are used to force a spatially distributed agro-hydrological model in order to evaluate Climate Change (CC) effects on local groundwater extraction (GWE). The slight increase of precipitation may alleviate current groundwater depletion on average, despite the increased evaporation due to warming. Nevertheless, projected climatic extremes create worse GWE shortages than for present climate. Local conditions may lead to opposing impacts on GWE, from increases to decreases (+/-20 mm/year), for a given spatially homogeneous CC forcing. Areas vulnerable to CC in terms of irrigation apportionment are thus identified. Our results emphasize the importance of accounting for local characteristics (water harvesting systems and maximal aquifer capacity versus GWE) in developing measures to cope with CC impacts in the South Indian region.

    This paper examines the social structures, culture, gendered roles, and their implications for suicidal behavior in South India. Exploring the cultural process within the structures of family and society to understand suicide and attempted suicide from the perspectives of survivors, mental health professionals, and traditional healers has not been achieved in the existing suicide-related research studies conducted in India to date. This study aimed to explore the cultural implications of attempted suicide by examining the survivors' life stories, their perceptions, and service providers' interpretations of problem situation. A qualitative design was used drawing on constant comparison method and thematic analysis. The analysis was underpinned by the theoretical concepts of Bourdieu's work. In-depth interviews were conducted with 15 survivors of attempted suicide, eight mental health professionals, and eight traditional healers from Southern India. The study found interactions among visible and invisible fields such as faith, power, control, culture, family, religion, and social systems to have strengthened the disparities in gender and role structures within families and societies and to have impacted survivors' dispositions to situations. The role of culture in causing suicide and attempted suicide is explained by unraveling the negative impact of interacting cultural and structural mechanisms.

  5. Thinking beyond Secularism: The Catholic Church and Political Practice in Rural South India

    2012-04-01

    Full Text Available This article re-opens the debate on secularism in India by looking at a religion and a region that has historically been marginal to this discourse, focusing on the way in which the Catholic Church has historically mediated the relationship between individuals and the state, among the fishing communities of South India. The Catholic Church’s dominant position among the fishing communities, its minority status within India, as well as theological and other shifts that have taken place within the global Church, lead it to articulate a secular, even radical politics as its primary mode of religious engagement. Radical clergy, many from fishing backgrounds, act as both organic and traditional intellectuals in the Gramscian sense, linking the traditional religious concerns of the Church to the secular interests of their parishioners. Likewise, villagers participate in Church-generated associations spaces to secure wider political goals. The paper concludes that certain forms of religious organisation in the public sphere might indeed be compatible with democracy, citizenship, and even secularism.

    Soil testing and analysis has become essential before commencement of any activity or process on soil i.e. residential construction, road construction etc. It is the most important work particularly in coastal area as these areas are more vulnerable to the natural disastrous like tsunami and cyclone. In India, there is lack of facility to collect and analyse the soil from the field. Hence, to study the various characteristics of the coastal region sub soil, Old Mahabalipuram area, which is the South East region of India has been chosen in this study. The aim of this study is to collect and analyse the soil sample from various localities of the Old Mahabalipuram area. The analysed soil data will be helpful for the people who are working in the field of Geotechnical in coastal region of India to make decision. The soil sample collected from different boreholes have undergone various field and laboratory tests like Pressuremeter Test, Field Permeability Test, Electrical Resistivity Test, Standard Penetration Test, Shear Test, Atterberg Limits etc. are performed including rock tests to know the geotechnical properties of the soil samples for each and every stratum

    While exploring experiences of psychological distress among psychiatric outpatients in Southern India, we set out to further understand interpersonal and socio-cultural factors that are associated with depressive symptoms. Using a grounded theory framework, we thematically coded narrative accounts of the women who sought treatment at the psychiatric clinic. In addition, we included author notes from participant observation and field work experiences in the South Indian psychiatric clinic. Of the 32 women who participated in the study, 75 % qualified for a diagnosis of a current major depressive episode. Depressive symptoms were associated with experiences of domestic violence and, in Farmer's terms, structural violence. Although only a partial response to gender-based suffering, allopathic psychiatric treatment seemed the best available means of coping with their circumstances. The paper moves beyond a medicalized model of disease and behavior to explore social and contextual factors that enabled these women to brave additional stigmas surrounding psychiatric treatment and seek a better outcome for themselves. It concludes by discussing the need for a multi-layered approach to addressing the suffering that women in South India experience.

    Full Text Available The spatial variation in the dinoflagellate cyst assemblage from the south-eastcoast of India is presented along with a comparison of the cyst abundance from other regions of the world. Samples from 8 stations revealed the presence of 24 species from the genera Protoperidinium, Zygabikodinium, Gonyaulax, Lingulodinium and Gyrodinium. Cyst abundance was comparatively high at northern stations and was well correlated with the fine-grained (silt-clay dominated sediments. In contrast, low cyst abundance was recorded in sandy sediments at southern stations. Fourteen cyst-forming dinoflagellate species previously unrecorded in planktonic samples were detected in the sediments. Thecyst abundance recorded here is low (29-331 cysts g-1 dry sediment as compared to sub-tropical and temperate regions, but it is on a par with tropical regions, including the west coast of India. Comparison of the cyst assemblage along the Indian coast revealed a smaller number of potentially harmful and red-tide-forming dinoflagellate species on the south-east coast (6 species than on the west coast (10 species. Furthermore, calcareous cysts of the genus Scrippsiella reported from the west coast were not observed in this study although their planktonic cells have been reported

    1995-01-01

    Though located in the tropics, India is endowed with substantial wind resources because of its unique geographical location which gets fully exposed to both the south-west and north-east monsoon winds. The westerly winds of the south-west monsoons provide bulk of the wind potential. Areas with mean annual wind speed exceeding 18 k mph and areas with mean annual power density greater than 140 W/m 2 have been identified using the wind data collected by the wind monitoring project funded by the Ministry of Non-conventional Energy Sources (MNES). Seasonal variations in wind speed at selected locations are discussed as also the frequency distribution of hourly wind speed. Annual capacity factors for 250 kW wind electric generators have been calculated for several typical locations. A good linear correlation has been found between mean annual wind speed and mean annual capacity factor. A method is described for assessing wind potential over an extended region where adequate data is available. It is shown that the combined wind energy potential over five selected areas of limited extent in Gujarat, Andhra Pradesh and Tamil Nadu alone amounts to 22,000 MW under the assumption of 20 per cent land availability for installing wind farms. For a higher percentage of land availability, the potential will be correspondingly higher. (author). 12 refs., 6 figs., 3 tabs

    The purpose of this study was to understand perceived benefits, facilitators, disadvantages, and barriers for physical activity among South Asian adolescents in India and Canada. Thirteen focus group discussions with South Asian (origin) adolescent boys and girls of different nutritional status and socioeconomic status in rural and urban India and urban Canada. Across the groups, fitness and 'energy' were perceived to be major benefits of physical activity. In India, better academic performance was highlighted, while health benefits were well detailed in Canadian groups. In all settings, friends, family, and teachers were perceived as facilitators of as well as barriers to physical activity. Lack of a safe space to play was a major concern for urban adolescents, while academic pressures and preference for other sedentary recreational activities were common barriers across all groups. Girls were less likely than boys to be interested in physical activity, with girls' participation in India further limited by societal restrictions. The study suggests key areas for promotion of physical activity among South Asian adolescents: balance between academic pressure and opportunities for physical activity, especially in India; urban planning for a built environment conducive to physical activity; and gender-sensitive programming to promote girls' activity which also addresses culture-specific barriers.

    Full Text Available Background and Aim: A community-based rehabilitation programme, Sri Ramachandra University-Transforming Faces project, was initiated to provide comprehensive management of communication disorders in individuals with CLP in two districts in Tamil Nadu, India. This community-based programme aims to integrate hospital-based services with the community-based initiatives and to enable long-term care. The programme was initiated in Thiruvannamalai (2005 district and extended to Cuddalore (2011. The aim of this study was to identify needs related to speech among children with CLP, enroled in the above community-based programme in two districts in Tamil Nadu, India. Design: This was a cross–sectional study. Participants and Setting: Ten camps were conducted specifically for speech assessments in two districts over a 12-month period. Two hundred and seventeen individuals (116 males and 101 females> 3 years of age reported to the camps. Methods: Investigator (SLP collected data using the speech protocol of the cleft and craniofacial centre. Descriptive analysis and profiling of speech samples were carried out and reported using universal protocol for reporting speech outcomes. Fleiss' Kappa test was used to estimate inter-rater reliability. Results: In this study, inter-rater reliability between three evaluators revealed good agreement for the parameters: resonance, articulatory errors and voice disorder. About 83.8% (n = 151/180 of the participants demonstrated errors in articulation and 69% (n = 124/180 exhibited abnormal resonance. Velopharyngeal port functioning assessment was completed for 55/124 participants. Conclusion: This study allows us to capture a “snapshot” of children with CLP, living in a specific geographical location, and assist in planning intervention programmes.

    Interest has grown recently in the issues of third tier or emerging nuclear suppliers. These are states that could export nuclear equipment, services, or technology but are outside the export control framework of the London Nuclear Supplier Group (NSG). The concern is that they may conduct nuclear trade without adequate safeguards, thus weakening the nonproliferation regime or even contributing to nuclear proliferation. The volume of nuclear sales by emerging suppliers is still minuscule, and it is unclear how far their export practices will diverge from the NSG framework. This case study of Indian nuclear supplier capability and practice is an effort to discern the type of path India is likely to adopt. This paper examines four aspects of India's nuclear activity for clues to India's potential role as an emerging nuclear supplier: foreign transactions; nuclear decision making; policy norms; and nuclear industrial capabilities

    Nearly 300,000 women die from pregnancy-related complications each year. One-fifth of these deaths occur in India. Maternal survival rose on India's national policy agenda in the mid-2000s, but responsibility for health policy and implementation in the federal system is largely devolved to the state level where priority for the issue and maternal health outcomes vary. This study investigates sources of variation in maternal health policy and implementation sub-nationally in India. The study is guided by four analytical categories drawn from policy process literature: constitutional, governing and social structures; political contexts; actors and ideas. The experiences of two south Indian states-Tamil Nadu a leader and Karnataka a relatively slow mover-are examined. Process-tracing, a case study methodology that helps to identify roles of complex historical events in causal processes, was employed to investigate the research question in each state. The study is informed by interviews with public health policy experts and service delivery professionals, observation of implementation sites and archival document analysis. Historical legacies-Tamil Nadu's non-Brahmin social movement and Karnataka's developmental disparities combined with decentralization-shape the states' political contexts, affecting variation in maternal health policy and implementation. Competition to advance consistent political priorities across regimes in Tamil Nadu offers fertile ground for policy entrepreneurship and strong public health system administration facilitates progress. Inconsistent political priorities and relatively weak public health system administration frustrate progress in Karnataka. These variations offer insights to the ways in which sub-national political and administrative contexts shape health policy and implementation. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Adolescence is a period of life that is a bridge between childhood and adulthood. India has the world's largest adolescent girl's population, and adolescent girls are an important vulnerable group of population. Perceived health is a predictor of morbidity and mortality in adults and has been an important marker of the health status in population health studies for decades. The aim of the study was to describe adolescent's perception of health and association between some factors such as nutrition status, socioeconomic status (SES), and health status. As their perception of health discomfort affects their health behavior and self-care, therefore, their health status is an important matter to discuss. A cross-sectional study was conducted in urban areas from a major city in South India. Six hundred and fifty adolescent female students aged 10-19 years formed the study population. Standardized self-reporting questionnaires were used to obtain relevant data regarding demographic features, SES, and health status. BMI calculated for each individual. The data were analyzed using SPSS version 16. About 83.3% of participants ranked their health status as good to excellent. A majority of the girls had one or more problems related to their menstrual cycles. The most common occurring problem was headache (45.3%). 47.8% of participants exhibited symptoms of mild insomnia. Strong significant association between nutritional status and SES was found. Higher percentage of undernourished adolescents belonged to low SES. Adolescents are expected to enjoy good health, but this does not seem to be the case in the developing countries like India, where poverty, malnutrition, and repeated infection are rampant. Majority of the problems such as healthy nutrition and self-care can be solved by community-based programs, health education, and food fortification.

    Full Text Available In India, entrepreneurship has traditionally been considered a male prerogative. However, in tandem with a changing socio-cultural environment and an increase in educational opportunities, women have started recognising their inherent talents and business skills. With the help of various governmental and non-governmental agencies, growing numbers of women are joining the ranks of entrepreneurs. However, in the existing familial and societal setup, entrepreneurial women are overburdened and find it increasingly difficult to balance their work and life roles. Therefore, the major objective of the present study was to develop and validate an appropriate tool to illustrate the work-life balance (WLB issues faced by women entrepreneurs of South India. We also sought to understand the important factors influencing the WLB of these women entrepreneurs. To achieve this end, data were collected by area sampling (cluster- random paired with semi-structured interviews and a questionnaire. The generated data were subjected to standard statistical procedures, such as factor analysis, regression analysis, analysis of variance (ANOVA and student's t-test. The five-point psychometric tool developed consisted of 39 statements related to five factors. Each of the statements possessed adequate reliability and validity. This study revealed that role overload, dependent care issues, quality of health, problems in time management and lack of proper social support are the major factors influencing the WLB of women entrepreneurs in India. Furthermore, even though the vast majority of the entrepreneurs examined in this study suffers from WLB issues, there are significant differences in the level of WLB issues faced by the various categories of women entrepreneurs. The present study provides recommendations for human resource professionals, management consultants, academicians and women entrepreneurs themselves to deal with the major WLB issues faced by Indian women

    Full Text Available INTRODUCTION: Osteosarcoma is the most common primary malignant bone tumor in children and adolescents, accounting for 4% of all childhood cancers worldwide. In India, the incidence varies from 4.7% to 11.6%, where this malignancy is associated with significant morbidity and mortality. There is paucity of demographic and clinical data for osteosarcoma in India. Objective: To retrospectively assess the demographic and clinical profile of pediatric osteosarcoma presenting at a tertiary cancer care centre of South India. Materials and Methods: From January 2010 to December 2013, all children under the age of 15 years diagnosed with osteosarcoma on histopathology were retrospectively analyzed for age, gender, rural or urban location, history, location of tumour, investigations, stage and histopathological subtype. The findings were formulated to chart the demographic and clinical profile. Results: A total of 37 cases of pediatric osteosarcoma were analyzed. The median age was 13 years with only three patients under the age of 10 years. There was a slight female preponderance with male: female ratio of 1:1.3. Most common mode of presentation was with pain and swelling of local site. Three patients had presented with a pathological fracture. The most common site involved was the distal femur. Over 90% of the cases were conventional osteosarcoma. Around 32% of patients had stage IV disease at presentation. Around 37% of patients from rural areas and 20% of patients from urban areas presented with metastatic disease. Conclusions: The aim of the study was the demographic and clinical description of osteosarcoma in the pediatric age group. A slight female preponderance was noted. The most common sites were consistent with western data except for an increased incidence in the fibula. There was an increased incidence of metastatic disease as compared to western population and a larger proportion of these patients seemed to come from rural areas.

    Full Text Available Creutzfeldt-Jakob disease (CJD is a rare, fatal neurodegenerative disease caused by an infectious protein called prion and is characterized by spongiform changes, neuronal loss, reactive astrocytic proliferation, and accumulation of pathologic cellular protein. Clinical presentation of CJD is characterized by rapidly progressive dementia, neurologic symptoms and visual impairment, and the development of akinetic mutism, which can mimic many neurological conditions. The diagnosis is based on clinical presentation, electroencephalogram, and typical cerebrospinal fluid and magnetic resonance imaging (MRI findings. Literature on the incidence and prevalence of CJD is lacking in South India. We report the case of a 57-year-old woman with progressive dementia and typical neurologic symptoms, myoclonic jerks, and MRI findings of CJD. This case highlights the need for a high index of suspicion to diagnose CJD.

    Full Text Available The land-sea breeze systems, the most interesting phenomena observed at coastal regions, have significant impact on the costal wave characteristics. Present study also focuses the diurnal variations of winds and its impact on wave parameters like significant wave height and mean wave period off Ennore port located in the south east coast of India The impact of the diurnal variation of winds on complex wave patterns in the coastal regions of Indian Ocean have been addressed earlier also. In the present study an attempt has been made to explore the impact of diurnal variation of winds on coastal waves using numerical model forced with European Centre for Medium Range Weather Forecasts (ECMWF and National Centre for Environmental Prediction (NCEP blended wind fields. It has been observed that most of the time, the ECMWF blended wind field reproduces the diurnal variation.

    A 10-year study of Giardia intestinalis infections in adults was conducted in the Dakshina Kannada District of Karnataka State, South India. Coproparasitological investigations were made on 10,000 stool specimens collected from selected patients. The infection rate was 37.1% with a male disease rate of 91.4%. The highest incidence rate was recorded in the age group 15-26 years. A possible reason for this preponderance of giardiasis in these males, is discussed. The optimum time for transmission appeared to be during the warmer months of the year (May to October) which coincided with the greatest amount of rainfall. The most common symptoms were abdominal discomfort, flatulence, diarrhoea, weight loss and anorexia. The predominating symptoms in our series varied with socio-economic level. There appeared to be some correlation between the clinical manifestations and the immune status of the individual.

    Concentrations of five rare earth elements (REE) were measured in clay samples of a deep bore hole comprising major aquifers of Pondicherry region, south India in order to investigate the geochemical variations among various litho-units. Clay samples from Cretaceous formation show distinct gray to black color whereas Tertiary deposits have clays with color varying from pale yellow to brown to gray. All measured REEs exhibit lower concentrations than Upper Continental Crust (UCC) average values. Large variations in REEs contents were observed in different sedimentary formations (Tertiary and Cretaceous). Chondrite normalized ratio of La/Lu and Eu/Eu* indicate that the clays are derived from weathering of felsic rock and possibly under humid climate. All the samples showed positive Eu anomaly in North American Shale Composite (NASC) normalized plot which shows plagioclase feldspar as the major contributor to these clays. Positive Eu anomaly is also an indication of reduced condition of the formation. (author)

    Whether perceived or enacted, HIV-related stigma is widespread in India, and has had a crippling effect on People Living with HIV/AIDS (PLHA). Research has shown that a positive attitude towards the illness sets a proactive framework for the individual to cope with his or her infection; therefore, healthy coping mechanisms are essential to combat HIV-related stigma. This qualitative study involving in-depth interviews and focus group discussions with PLHA affiliated with HIV support groups in South India explored positive coping strategies employed by PLHA to deal with HIV-related stigma. Interviews and focus group discussions were translated, transcribed, and analyzed for consistent themes. Taboos surrounding modes of transmission, perceiving sex workers as responsible for the spread of HIV, and avoiding associating with PLHA provided the context of HIV-related stigma. Despite these challenges, PLHA used several positive strategies, classified as Clear Knowledge and Understanding of HIV, Social Support and Family Well-Being, Selective Disclosure, Employment Building Confidence, and Participation in Positive Networks. Poor understanding of HIV and fears of being labeled immoral undermined healthy coping behavior, while improved understanding, affiliation with support groups, family support, presence of children, and financial independence enhanced PLHA confidence. Such positive coping behaviours could inform culturally relevant interventions.

    Alcohol consumption in India is disproportionately higher among poorer and socially marginalised groups, notably Scheduled Tribes (STs). We lack an understanding of STs own views with regard to alcohol, which is important for implementing appropriate interventions. This study was undertaken with the Paniyas (a previously enslaved ST) in a rural community in Kerala, South India. The study, nested in a participatory poverty and health assessment (PPHA). PPHA aims to enable marginalized groups to define, describe, analyze, and express their own perceptions through a combination of qualitative methods and participatory approaches (e.g. participatory mapping and ranking exercises). We worked with 5 Paniya colonies between January and June 2008. Alcohol is viewed as a problem among the Paniyas who reported that consumption is increasing, notably among younger men. Alcohol is easily available in licensed shops and is produced illicitly in some colonies. There is evidence that local employers are using alcohol to attract Paniyas for work. Male alcohol consumption is associated with a range of social and economic consequences that are rooted in historical oppression and social discrimination. Future research should examine the views of alcohol use among a variety of marginalised groups in developing countries and the different policy options available for these populations. In addition, there is a need for studies that untangle the potential linkages between both historical and current exploitation of marginalized populations and alcohol use.

    The residue levels of persistent organochlorines, such as HCH (BHC: 1,2,3,4,5,6-hexachlorocyclohexane) isomers, DDT [1,1,1-trichloro-2,2-bis (p-chlorophenyl) ethane] compounds, PCBs (polychlorobiphenyls) and HCB (hexachlorobenzene), were measured in wildlife. The wildlife were sampled from terrestrial and aquatic habitats in and around the agricultural watershed of Parangipettai, South India. On the basis of overall concentrations sigma HCH ranked first followed by sigma DDT, sigma PCB and HCB, reflecting the increasing usage of HCH in recent years in India. The residue levels of organochlorines in birds varied according to their feeding habits and showed the following pattern: inland piscivores and scavengers greater than coastal piscivores greater than insectivores greater than omnivores greater than granivores. High levels of HCH and DDT residues were recorded in Pond heron and Cattle egret which feed in the agricultural fields. Comparison of HCH concentrations in fish and birds in the study area to other locations was made to further understand the dynamics of contaminant accumulation in tropical wildlife. Regarding birds, a wide variation in residue levels could be seen among various countries, with tropical regions registering high levels. In contrast, the variation is not prominent in the case of fish. The residue levels in fish measured in the present study were generally comparable to values reported from other locations. This suggests that the bioavailability of contaminants to the aquatic fauna is less due to the smaller flux and shorter residence time of these chemicals in the tropics.

    Cultural and religious beliefs influence perceptions about health and illness. Data, from India, on perceptions about intellectual disability are scant. This study explored people's cultural beliefs and attitudes about intellectual disability, perceived needs and burden associated with care in Vellore, south India. A qualitative methodology using focus groups was employed. Eight focus groups were conducted in three settings and included the mothers of children and adolescents with intellectual disability (four groups, n = 29), community health workers (two groups, n = 17) and schoolteachers (two groups, n = 16). Our results suggest that cultural and religious beliefs perpetuated negative attitudes towards disability. This meant that caregivers bore a high burden of care with little support from family or society. The study confirmed the presence of diverse, multiple and contradictory models of disability drawing from biomedical and local religious, social and cultural constructs. Public awareness, education and community-level interventions for reducing the misconceptions and stigma related to intellectual disability are needed in addition to culturally sensitive treatment methods to improve the attitude towards and management of intellectual disability.

    Background: In the modern era, the major cause of gastric outlet obstruction (GOO) is known to be a malignancy, especially in the developed world. Many books and articles do suggest that the benign causes continue to be the major cause of GOO in the developing world however, there is growing evidence proving the contrary. Males were (more commonly) affected females and individuals in their fifth and sixth decade have been the predominant age group in the majority of studies. There is a minimal data of GOO from South India. Aims: A retrospective analysis of the endoscopic findings of patients presenting with features of GOO to determine the demographic and etiological patterns. Materials and Methods: A retrospective study of the endoscopic findings of patients with GOO from January 2005 to January 2014 was done. The diagnosis of GOO was based on clinical presentation, and an inability during the upper endoscopy to enter the second portion of the duodenum as documented in the endoscopy registers. Patients who have already been diagnosed with malignancy prior to the endoscopy were excluded from the study; so were the patients with gastroparesis. Results: A total of 342 patients with GOO underwent the endoscopy during the study period. The causes for benign obstruction were predominantly peptic ulcer disease. The major cause for malignant obstruction was carcinoma of stomach involving the distal stomach. The male to female ratio was 3.2:1. The patients with malignancy were older than patients with benign disorders. Most of the patients were in the sixth and seventh decade. The risk of malignancy was higher with increasing age, especially in women. A fourth of all carcinoma stomach presented with GOO. Conclusion: The study demonstrates that the cause for GOO in Kerala, South India is predominantly malignancy. The etiological and demographic patterns were similar to the studies conducted in the developed nations. PMID:26605204

    Full Text Available Objectives: Malocclusion plays an important role in the overall oral health of an individual because it is associated with periodontal disease, temporomandibular disorders and may be complicated by an individual′s disparity. Careful attention to malocclusion in children with special needs leads to a considerable improvement in the quality-of-life. The objective of the present study was to analyze the prevalence of malocclusion and its association with determinant factors in individuals with special needs in South India. Materials and Methods: A cross-sectional study was carried out that included 844 individuals with special needs and their mothers at eleven institutions in South India. Data were collected based on the questionnaire given to the mothers and dental examination carried out on the children. The nutritive and non-nutritive oral habits were obtained from the reports of the mothers. Clinical examination recorded the following: Class I, Class II, Class III, anterior crowding, anterior spacing, deep bite, open bite, and anterior cross bite. Statistical analyses of data were performed using Chi-square test. Results: Results at the end of the study revealed anterior crowding in 27.37% of the total sample size, deep bite in 20.5%, Class I in 14.34%, anterior spacing in 12.9%, Class II in 9.95%, Class III in 5.33%, anterior cross bite in 4.98% and open bite in 4.62%. Conclusion: The prevalence of malocclusion in individuals with special needs is associated with the type of disability and it is more in males than females. Mentally disabled individuals had higher frequencies of all types the malocclusion. Prevalence of anterior crowding was higher compared to other types of malocclusion followed by deep bite.

    Full Text Available Introduction and Objectives: In recent times, audio-video (A-V recording of consent process for all the study subjects entering a clinical trial has been made mandatory. A-V recording of informed consent process is a big challenge due to confidentiality and the sociocultural environment in India. It is important to find out the acceptability for A-V recording of the consent process and reasons for refusal, if any to address this new challenge. Materials and Methods: A descriptive survey was done among 150 residents of a rural community of South India. Acceptability for A-V recording of consent process was assessed among those who had given the informed written consent for participation in the study. An attempt to find the factors determining the refusal was also made. Results: More than one-third (34% of the study subjects refused to give consent for A-V recording of consent process. Not interested in recording or don′t like to be recorded (39% were the most common reasons to refuse for A-V recording of consent process. The refusal was higher among female and younger age-group adult subjects. Socioeconomic status was not found to be significantly associated with refusal to consent for A-V recording. Conclusion: Refusal for A-V recording of consent process is high in the South Indian rural population. Before any major clinical trial, particularly a field trial, an assessment of consent for A-V recording would be helpful in recruitment of study subjects.

    Full Text Available Purpose: To understand the reasons why people in rural south India with visual impairment arising from various ocular diseases do not seek eye care. Materials and Methods: A total of 5,573 persons above the age of 15 were interviewed and examined in the South Indian state of Andhra Pradesh covering the districts of Adilabad, West Godavari and Mahaboobnagar. A pre-tested structured questionnaire on barriers to eye care was administered by trained field investigators. Results: Of the eligible subjects, 1234 (22.1%, N=5573 presented with distant visual acuity < 20/60 or equivalent visual field loss in the better eye. Of these, 898 (72.7%, N=1234 subjects had not sought treatment despite noticing a decrease in vision citing personal, economic and social reasons. The analysis also showed that the odds of seeking treatment was significantly higher for literates [odds ratio (OR 1.91, 95% confidence interval (CI 1.38 to 2.65], for those who would be defined as blind by visual acuity category (OR 1.35, 95% CI 0.96 to 1.90 and for those with cataract and other causes of visual impairment (OR 1.50, 95% CI 1.11 to 2.03. Barriers to seeking treatment among those who had not sought treatment despite noticing a decrease in vision over the past five years were personal in 52% of the respondents, economic in 37% and social in 21%. Conclusion: Routine planning for eye care services in rural areas of India must address the barriers to eye care perceived by communities to increase the utilization of services.

    We present new shear wave splitting and splitting intensity measurements from SK(K)S phases recorded at seismic stations of the Malaysian National Seismic Network. These results, in conjunction with results from Tibet and Yunnan provide a basis for testing the degree to which Indochina and South China Sea upper mantle fabrics are responses to India-Eurasia collision. Upper mantle fabrics derived from shear wave splitting measurements in Yunnan and eastern Tibet parallel geodetic surface motions north of 26°N, requiring transmission of tractions from upper mantle depths to surface, or consistent deformation boundary conditions throughout the upper 200 km of crust and mantle. Shear wave splitting fast trends and surface velocities diverge in eastern Yunnan and south of 26°N, indicating development of an asthenospheric layer that decouples crust and upper mantle, or corner flow above the subducted Indo-Burma slab. E-W fast shear wave splitting trends southwest of 26°N/104°E indicate strong gradients in any asthenospheric infiltration. Possible upper mantle flow regimes beneath Indochina include development of olivine b-axis anisotropic symmetry due to high strain and hydrous conditions in the syntaxis/Indo-Burma mantle wedge (i.e., southward flow), development of strong upper mantle corner flow in the Indo-Burma wedge with olivine a-axis anisotropic symmetry (i.e., westward flow), and simple asthenospheric flow due to eastward motion of Sundaland shearing underlying asthenosphere. Further south, shear-wave splitting delay times at Malaysian stations vary from 0.5 seconds on the Malay Peninsula to over 2 seconds at stations on Borneo. Splitting fast trends at Borneo stations and Singapore trend NE-SW, but in northern Peninsular Malaysia, the splitting fast polarization direction is NW-SE, parallel to the trend of the Peninsula. Thus, there is a sharp transition from low delay time and NW-SE fast polarization to high delay times and fast polarization directions that

    Indian data have been largely missing from genome-wide databases that provide information on genetic variations in different populations. This hinders association studies for complex disorders in India. This study was aimed to determine whether the complex genetic structure and endogamy among Indians could potentially influence the design of case-control studies for autoimmune disorders in the south Indian population. A total of 12 single nucleotide variations (SNVs) related to genes associated with autoimmune disorders were genotyped in 370 healthy individuals belonging to six different caste groups in southern India. Allele frequencies were estimated; genetic divergence and phylogenetic relationship within the various caste groups and other HapMap populations were ascertained. Allele frequencies for all genotyped SNVs did not vary significantly among the different groups studied. Wright's FSTwas 0.001 per cent among study population and 0.38 per cent when compared with Gujarati in Houston (GIH) population on HapMap data. The analysis of molecular variance results showed a 97 per cent variation attributable to differences within the study population and <1 per cent variation due to differences between castes. Phylogenetic analysis showed a separation of Dravidian population from other HapMap populations and particularly from GIH population. Despite the complex genetic origins of the Indian population, our study indicated a low level of genetic differentiation among Dravidian language-speaking people of south India. Case-control studies of association among Dravidians of south India may not require stratification based on language and caste.

    Lower tropospheric (surface to 600 hPa) ozone over India poses serious risks to both human health and crops, and potentially affects global ozone distribution through frequent deep convection in tropical regions. Our current understanding of the processes controlling seasonal and long-term variations in lower tropospheric ozone over this region is rather limited due to spatially and temporally sparse observations. Here we present an integrated process analysis of the seasonal cycle, interannual variability, and long-term trends of lower tropospheric ozone over India and its linkage to the South Asian monsoon using the Ozone Monitoring Instrument (OMI) satellite observations for years 2006-2014 interpreted with a global chemical transport model (GEOS-Chem) simulation for 1990-2010. OMI observed lower tropospheric ozone over India averaged for 2006-2010, showing the highest concentrations (54.1 ppbv) in the pre-summer monsoon season (May) and the lowest concentrations (40.5 ppbv) in the summer monsoon season (August). Process analyses in GEOS-Chem show that hot and dry meteorological conditions and active biomass burning together contribute to 5.8 Tg more ozone being produced in the lower troposphere in India in May than January. The onset of the summer monsoon brings ozone-unfavorable meteorological conditions and strong upward transport, which all lead to large decreases in the lower tropospheric ozone burden. Interannually, we find that both OMI and GEOS-Chem indicate strong positive correlations (r = 0.55-0.58) between ozone and surface temperature in pre-summer monsoon seasons, with larger correlations found in high NOx emission regions reflecting NOx-limited production conditions. Summer monsoon seasonal mean ozone levels are strongly controlled by monsoon strengths. Lower ozone concentrations are found in stronger monsoon seasons mainly due to less ozone net chemical production. Furthermore, model simulations over 1990-2010 estimate a mean annual trend of 0

    Full Text Available Background: Four out of five adults with diabetes live in low- and middle-income countries (LMIC. India has the second highest number of diabetes patients in the world. Despite a huge burden, diabetes care remains suboptimal. While patients (and families play an important role in managing chronic conditions, there is a dearth of studies in LMIC and virtually none in India capturing perspectives and experiences of patients in regard to diabetes care. Objective: The objective of this study was to better understand constraints faced by patients from urban slums in managing care for type 2 diabetes in India. Design: We conducted in-depth interviews, using a phenomenological approach, with 16 type 2- diabetes patients from a poor urban neighbourhood in South India. These patients were selected with the help of four community health workers (CHWs and were interviewed by two trained researchers exploring patients’ experiences of living with and seeking care for diabetes. The sampling followed the principle of saturation. Data were initially coded using the NVivo software. Emerging themes were periodically discussed among the researchers and were refined over time through an iterative process using a mind-mapping tool. Results: Despite an abundance of healthcare facilities in the vicinity, diabetes patients faced several constraints in accessing healthcare such as financial hardship, negative attitudes and inadequate communication by healthcare providers and a fragmented healthcare service system offering inadequate care. Strongly defined gender-based family roles disadvantaged women by restricting their mobility and autonomy to access healthcare. The prevailing nuclear family structure and inter-generational conflicts limited support and care for elderly adults. Conclusions: There is a need to strengthen primary care services with a special focus on improving the availability and integration of health services for diabetes at the community level

    The coastal zone is one of the nation's greatest environmental and economic assets. The present research aims at studying the shoreline changes along Vedaranyam coast using conventional and modern techniques including field sampling, remote sensing, and geographical information system (GIS). The study area was divided into three zones. Dynamic Land/Sea polygon analysis was performed to obtain the shore line changes at different time periods between 1930 and 2005. From the multidate shoreline maps, the rate of shoreline change was computed using linear regression rate and end point rate. Further, the shoreline was classified into eroding, accreting, and stable regions through GIS analysis. The eroding, accreting, and stable coastal stretch along Vedaranyam is observed as 18 %, 80.5 %, and 1.5 %, respectively. Net shoreline movement is seaward, i.e., the coast is progressive with an average rate of 5 m/year. A maximum shoreline displacement of 1.3 km towards the sea is observed near Point Calimere. During the Asian Tsunami 2004, the eastern part of the study area showed high erosion. Sediment transport paths derived from the grain size analysis of beach sediments collected during different seasons help to identify the major sediment source and sinks. Point Calimere acts as the major sink for sediments whereas Agastiyampalli and Kodiakkarai are found to be the major sources for the sediment supply along the Vedaranyam coast. Shoreline change study from field and satellite data using GIS analysis confirms that Vedaranyam coast is accreting in nature.

    Hyperspectral Remote sensing is a tool to identify the minerals along with field investigation. Tamil Nadu has abundant minerals like 30% titanium, 52% molybdenum, 59% garnet, 69% dunite, 75% vermiculite and 81% lignite. To enhance the user and industry requirements, mineral extraction is required. To identify the minerals properly, sophisticated tools are required. Hyperspectral remote sensing provides continuous extraction of earth surface information in an accurate manner. Nontronite is an iron-rich mineral mainly available in Nilgiri hills, Tamil Nadu, India. Due to the large number of bands, hyperspectral data require various preprocessing steps such as bad bands removal, destriping, radiance conversion and atmospheric correction. The atmospheric correction is performed using FLAASH method. The spectral data reduction is carried out with minimum noise fraction (MNF) method. The spatial information is reduced using pixel purity index (PPI) with 10000 iterations. The selected end members are compared with spectral libraries like USGS, JPL, and JHU. In the Nontronite mineral gives the probability of 0.85. Finally the classification is accomplished using spectral angle mapper (SAM) method.

    The purpose was to study the retinopathy status in diabetic patients with a risk of diabetic foot (DF) syndrome visiting a tertiary care hospital in South India. In this cross sectional study all patients with diabetes mellitus (DM) with a risk of DF syndrome, visiting a tertiary care hospital during the study period, underwent an ophthalmological evaluation for documentation of their retinopathy status. One hundred and eighty-two patients diagnosed to have a risk profile for DF syndrome were included in the study. Their mean age was 59.28 years and 75.27% were males. The mean duration of Type 1 and Type 2 variants of DM was 14.9 years and 10.9 years, respectively. Of the 182 patients, 67.58% had retinopathy changes. Proliferative diabetic retinopathy (DR) constituted 17.88% of the total patients with retinopathy. An increased presence of retinopathy in patients with an increased risk grade of DF was found significant by the Chi-square test (P < 0.001). Our study found an increased presence of DR in a South Indian cohort with DF syndrome. The severity of retinopathy was greater in patients with higher grades of risk for DF. The establishment of an association between DR and DF syndrome will help in developing an integrated management strategy for these two debilitating consequences of diabetes.

    Full Text Available Fortnightly survey in control and fire-impacted regions of scrub jungle of south-west coast of India during south-west monsoon (50 m2 quadrats up to 10 weeks yielded 34 and 25 species of macrofungi, respectively. The species as well as sporocarp richness were the highest during the fourth week, while the diversity attained the highest during the second week in control region. In fire-impacted region, the species and sporocarp richness and diversity peaked at sixth week. Seven species common to both regions were Chlorophyllum molybdites, Lepiota sp., Leucocoprinus birnbaumii, Marasmius sp. 3, Polyporus sp., Schizophyllum commune and Tetrapyrgos nigripes. The overall sporocarp richness was higher in fire-impacted than in control region. The Jaccard’s similarity between regions was 13.5%, while fortnights of regions ranged from 0% (10th week to 11.7% (eighth week. Control region showed single-species dominance by Xylaria hypoxylon, while multispecies dominance by Cyathus striatus and Lentinus squarrosulus in fire-impacted region. Except for air temperature, nine abiotic factors significantly differed between control and fire-impacted regions. The Pearson correlation was positive between species richness and phosphorus content in fire-impacted region (r = 0.696, while sporocarp richness was negatively correlated with pH in control region (r = −0.640. Economically viable species were 12 and 10 without overlap in control and fire-impacted regions, respectively.

    The aim of this study was to phylogenetically analyze Fasciola gigantica (F. gigantica) from mainland India and to reveal the expansion history of F. gigantica in the Indian subcontinent. We analyzed 40 Fasciola flukes that were collected from Delhi, in the Indian mainland, and identified them as F. gigantica by using nucleotide analyses of the nuclear phosphoenolpyruvate carboxykinase (pepck) and DNA polymerase delta (pold) genes. Based on the nucleotide sequence of mitochondrial NADH dehydrogenase subunit 1 (nad1) gene, the flukes had 18 haplotypes. The haplotypes were classified under haplogroup A, which is predominant in the F. gigantica of South Asia. The population genetics of haplogroup A revealed that Delhi population showed higher π value than eastern India population. These results suggest that F. gigantica of haplogroup A might have spread from the west to the east in India along with the artificial migration of the domestic Zebu cattle, Bos indicus.

    To develop and evaluate a Nutrition Transition-FFQ (NT-FFQ) to measure nutrition transition among adolescents in South India. We developed an interviewer-administered NT-FFQ comprising a 125-item semi-quantitative FFQ and a twenty-seven-item eating behaviour survey. The reproducibility and validity of the NT-FFQ were assessed using Spearman correlations, intra-class correlation coefficients (ICC), and levels of agreement using Bland-Altman and cross-classification over 2 months (NT-FFQ1 and NT-FFQ2). Validity of foods was evaluated against three 24-h dietary recalls (24-HR). Face validity of eating behaviours was evaluated through semi-structured cognitive interviews. The reproducibility of eating behaviours was assessed using weighted kappa (κ w) and cross-classification analyses. Vijayapura, India. A representative sample of 198 adolescents aged 14-18 years. Reproducibility of NT-FFQ: Spearman correlations ranged from 0·33 (pulses) to 0·80 (red meat) and ICC from 0·05 (fruits) to 1·00 (tea). On average, concordance (agreement) was 60 % and discordance was 7 % for food groups. For eating behaviours, κ w ranged from 0·24 (eating snacks while watching television) to 0·67 (eating lunch at home) with a mean of 0·40. Validity of NT-FFQ: Spearman correlations ranged from 0·11 (fried traditional foods) to 0·70 (tea) and ICC ranged from 0·02 (healthy global foods) to 1·00 (grains). The concordance and discordance were 48 % and 8 %, respectively. Bland-Altman plots showed acceptable agreement between NT-FFQ2 and 24-HR. The eating behaviours had acceptable face validity. The NT-FFQ has good reproducibility and acceptable validity for food intake and eating behaviours. The NT-FFQ can quantify the nutrition transition among Indian adolescents.

    Full Text Available Background: There is a need to generate data from India on relative frequencies of specific opportunistic infections (OIs in different regions and their relation to the choice of commonly used generic highly active anti-retroviral therapy (HAART regimens. Objectives: To document the prevailing prevalence pattern of OIs both before and after HAART, to look for reduction in OIs following HAART, to assess the risk of developing new OIs within 6 months of HAART initiation and to see if there is any difference in the risk of developing a new OI within 6 months of HAART initiation, for those on Efavirenz (EFV-based regimens and Nevirapine (NVP-based regimens. Materials and Methods: In a prospective observational cohort study conducted in South India involving 108 ART-naive AIDS patients, different pathogens were isolated and identified using standard laboratory techniques. Data analysis was done using SPSS software (version 16.0. Risk of developing an OI after HAART initiation was assessed using the likelihood ratio test from Cox regression models. Results: Tuberculosis (53.4%, oral Candidiasis (27.2% and Herpes Zoster (14.7% were the common infections seen. There was a drastic reduction of 96.59% in OI events after 6 months of HAART. The risk of developing an OI within 6 months of HAART initiation was 5.56%. Time to development of an OI in the first 6 months of HAART was shorter for the NVP-based regimens than with EFV-based regimens, but this difference was not statistically significant (HR=0.891, 95% CI: 0.179-4.429; P=0.888. Conclusion: Tuberculosis is the most important OI before initiation of HAART. Both EFV and NVP-based regimens are equally efficacious in controlling OIs.

    Full Text Available PURPOSE: To assess the prevalence and causes of visual impairment in weaving communities in Prakasam district in South India state of Andhra Pradesh. METHODS: Using Rapid Assessment of Visual Impairment (RAVI methodology, a population based cross-sectional study was conducted. A two-stage sampling strategy was used to select 3000 participants aged ≥40 years. Visual Acuity (VA was assessed using a tumbling E chart and ocular examinations were performed by trained Para medical ophthalmic personnel. A questionnaire was used to collect personal and demographic information. Blindness and moderate Visual Impairment (VI was defined as presenting VA <6/60 and <6/18 to 6/60 respectively. VI included blindness and moderate VI. RESULTS: 2848 of 3000 enumerated subjects (94.0% participated. 39% were in 40-49 years age group and 11.8% were aged ≥70 years, 55% were women and nearly half of them had no formal education. 400 (14%; 95% CI: 12.8-15.3 subjects had VI, including blindness in 131 (4.6%; 95% CI: 3.8-5.4 and moderate VI in 269 (9.4%; 95% CI: 8.3-10.5 individuals. On applying multiple logistic regression, VI was significantly associated with older age and no formal education. Though the odds of having VI were higher in females, it was of borderline statistical significance (p = 0.06. Refractive error was the leading cause of all VI followed by cataract (56%. However, refractive errors were the leading cause of moderate VI (73.2% and cataract was the leading cause of blindness (62.6%. 'Cannot afford the cost of services' was the leading barrier for utilization of eye care services (47%. CONCLUSIONS: There is a significant burden of VI in weaving communities in Andhra Pradesh, India most of which is avoidable. With this information as baseline, services need to be streamlined to address this burden.

A huge prevalence of type 1 diabetes among young patients is documented in literature; India is one of the countries with the highest number of new cases per year (10,900, of which 3–4 million face poverty along with diabetes. Objective: The aim of this study was to explore the perceptions of determinants of the disease burden among young patients with type 1 diabetes and their parents. Methods: In June 2014, perceptions were collected from eleven young patients and five available parents using the critical incident technique. Results: Disease burdens associated with the management of type 1 diabetes can vary significantly according to the different social and economic determinants facing each household. Determinants associated with good practices in the management of childhood type 1 diabetes included socioeconomic status, unawareness of health complications, and beliefs about nutrition. Coping strategies applied via lifestyle changes included monitoring glycemia and regular checkups by diabetologists. A general lack of awareness about type 1 diabetes in Indian society, stigmatization, and limited access and systematic barriers to the delivery of optimal health care were all perceived to be factors hindering the successful management of chronic type 1 diabetes by young patients and their parents. Conclusion: Stigmatization, a lack of therapeutic adherence, and the financial strains placed on families, particularly on poor ones, are critical. More emphasis must be put on the prevention of acute and long-term complications and education. Keywords: adolescents, adherence, critical incidence technique, India

    Full Text Available BACKGROUND: Adherence is central to the success of antiretroviral therapy. Supporting adherence has gained importance in HIV care in many national treatment programs. The ubiquity of mobile phones, even in resource-constrained settings, has provided an opportunity to utilize an inexpensive, contextually feasible technology for adherence support in HIV in these settings. We aimed to assess the influence of mobile phone reminders on adherence to antiretroviral therapy in South India. Participant experiences with the intervention were also studied. This is the first report of such an intervention for antiretroviral adherence from India, a country with over 800 million mobile connections. METHODS: STUDY DESIGN: Quasi-experimental cohort study involving 150 HIV-infected individuals from Bangalore, India, who were on antiretroviral therapy between April and July 2010. The intervention: All participants received two types of adherence reminders on their mobile phones, (i an automated interactive voice response (IVR call and (ii A non-interactive neutral picture short messaging service (SMS, once a week for 6 months. Adherence measured by pill count, was assessed at study recruitment and at months one, three, six, nine and twelve. Participant experiences were assessed at the end of the intervention period. RESULTS: The mean age of the participants was 38 years, 27% were female and 90% urban. Overall, 3,895 IVRs and 3,073 SMSs were sent to the participants over 6 months. Complete case analysis revealed that the proportion of participants with optimal adherence increased from 85% to 91% patients during the intervention period, an effect that was maintained 6 months after the intervention was discontinued (p = 0.016. Both, IVR calls and SMS reminders were considered non-intrusive and not a threat to privacy. A significantly higher proportion agreed that the IVR was helpful compared to the SMS (p<0.001. CONCLUSION: Mobile phone reminders may improve

    There is a slow but steady rise in the case detection rates of melioidosis from various parts of the Indian sub-continent in the past two decades. However, the epidemiology of the disease in India and the surrounding South Asian countries remains far from well elucidated. Multi-locus sequence typing (MLST) is a useful epidemiological tool to study the genetic relatedness of bacterial isolates both with-in and across the countries. With this background, we studied the molecular epidemiology of 32 Burkholderia pseudomallei isolates (31 clinical and 1 soil isolate) obtained during 2006-2015 from various parts of south India using multi-locus sequencing typing and analysis. Of the 32 isolates included in the analysis, 30 (93.7%) had novel allelic profiles that were not reported previously. Sequence type (ST) 1368 (n = 15, 46.8%) with allelic profile (1, 4, 6, 4, 1, 1, 3) was the most common genotype observed. We did not observe a genotypic association of STs with geographical location, type of infection and year of isolation in the present study. Measure of genetic differentiation (FST) between Indian and the rest of world isolates was 0.14413. Occurrence of the same ST across three adjacent states of south India suggest the dispersion of B.pseudomallei across the south western coastal part of India with limited geographical clustering. However, majority of the STs reported from the present study remained as "outliers" on the eBURST "Population snapshot", suggesting the genetic diversity of Indian isolates from the Australasian and Southeast Asian isolates.

    Brazil, Russia, India, China, and South Africa-the BRICS-show high overall economic growth rates by international standards. Even during the recent economic crisis, most BRICS countries still recorded above-average growth. This development has benefited German foreign trade in particular. This applies especially to automotive and mechanical engineering. However, this geographical reorientation of German export trade in favor of the BRICS countries could soon reach its limits.

  2. The collision of South China with NW India to join Gondwanaland in the Cambrian: Provenance constraints from foreland basins

    2013-12-01

    The paleogeographic position of the South China Block (SCB) during the early Paleozoic is important for understanding its affinity with Gondwanaland and addressing potential tectonic trigger for both the early Paleozoic Wuyi-Yunkai orogeny in South China and similar-aged orogenic events along Gondwanan margins. Detrital zircon U-Pb ages of Cambrian sandstones/metasandstones from the southwestern SCB reveal a predominant population at 1100¬-950 Ma, and zircon Hf-O isotopic results suggest three Precambrian episodes of juvenile crustal growth for the source provenance (ca. 3.0 Ga, ca. 2.5 Ga and ca. 1.0 Ga), with major crustal reworking at 0.58-0.50 Ga. This provenance record is distinctly different from the known tectonomagmatic record of the SCB, but matches well with the provenance record of Cambrian sandstones and Cambro-Ordovician tectonomagmatic events in the NW Indian Himalaya. Such a provenance linkage between the two continents appears to have started from the Ediacaran. We thus propose that the SCB likely collided with NW India during the assembling of Gondwanaland between the Ediacaran and the Cambrian. The collisional event propagated to eastern Himalaya during Cambro-Ordovician time as South China rotated relative to India to close the remnant ocean, causing the Cambro-Ordovician North India orogeny (also known as the Kurgiakh orogeny) along the Himalaya, as well as the intraplate Wuyi-Yunkai orogeny (>460-415 Ma) in South China. This collisional event also generated two peripheral foreland basins on both the Indian Gondwanaland and the South China sides. The foreland basin on the South China side (the Nanhua foreland basin), started as a failed Neoproterozoic continental rift, and appears to have experienced two stage of development. During the first stage between the Ediacaran and the Cambrian, the basin likely shared the same detrital sources as the foreland basin in NW India, with sediments predominantly derived from the East Africa orogen and the

    Full Text Available Abstract Background In the context of AVAHAN, the India AIDS Initiative of the Bill & Melinda Gates Foundation, general population surveys (GPS were carried out between 2006 and 2008 in Belgaum (northern, Bellary (mid-state and Mysore (southern districts of Karnataka state, south India. Data from these three surveys were analysed to understand heterogeneity in HIV risk. Methods Outcome variables were the prevalence of HIV and sexually transmitted infections (STIs. Independent variables included age, district, place of residence, along with socio-demographic, medical and behavioural characteristics. Multivariate logistic regression was undertaken to identify characteristics associated with HIV and differences between districts, incorporating survey statistics to consider weights and cluster effects. Results The participation rate was 79.0% for the interview and 72.5% for providing a blood or urine sample that was tested for HIV. Belgaum had the highest overall HIV (1.43% and Herpes simplex type-2 (HSV-2 (16.93% prevalence, and the lowest prevalence of curable STIs. In Belgaum, the HIV epidemic is predominantly rural, and among women. In Bellary, the epidemic is predominantly in urban areas and among men, and HIV prevalence was 1.18%. Mysore had the lowest prevalence of HIV (0.80% and HSV-2 (10.89% and the highest prevalence of curable STIs. Higher HIV prevalence among men was associated with increasing age (p25-29years=11.22,95%CI:1.42-88.74, AOR30-34years=13.13,95%CI:1.67-103.19 and AOR35-39years=11.33,95%CI:1.32-96.83, having more than one lifetime sexual partner (AOR=4.61,95%CI:1.26-16.91 and having ever used a condom (AOR=3.32,95%CI:1.38-7.99. Having a dissolved marriage (being widowed/divorced/separated was the strongest predictor (AOR=10.98,95%CI: 5.35-22.57 of HIV among women. Being a muslim woman was associated with lower HIV prevalence (AOR=0.27,95%CI:0.08-0.87. Conclusion The HIV epidemic in Karnataka shows considerable heterogeneity

    Full Text Available This article compares the intelligence systems of Brazil, Russia, India, China, and South Africa. Three questions drive the research: How are the national intelligence systems organized? How is power distributed among organizations in each country? What are the organizational risks? By employing Network Analysis to publicly-available data on intelligence agencies, collegiate bodies, and supervising organizations, authority relations and information flows were mapped. Regarding organizational configuration, similarities were found between India and Russia, as well as between China and South Africa. Brazil differs from the four countries. As for the power distribution, in Russia, Brazil, and India intelligence is subordinated to the government, and shows more centrality in the cases of China and South Africa. Finally, Russia runs the highest risk of having an intelligence system less able to adapt to strategic circumstances, at the same time being the most resilient among the five countries. Likewise, China has the highest risk of a single actor being able to retain information, acting as a gatekeeper. Network Analysis has proved to be a useful approach to promote a comparative research program in the Intelligence Studies field.

  6. India.

    1982-10-01

    This discussion of India focuses on the following: the history of the country's demographic situation; the government's overall approach to population problems; population data systems and development planning; institutional arrangements for the integration of population with development planning; the government's view of the importance of population policy in achieving development objectives; population size, growth and natural increase; morbidity and mortality; fertility; international migration; and spatial distribution. India's government views the population problem in the country as extremely serious particularly in relation to the alleviation of poverty. It was the 1st country to introduce a family planning program at the national level. Development plans have consistently treated the population situation as a priority issue. A relatively comprehensive system of data collection for demographic purposes has existed in India for a long time. The 1st census was conducted in 1872. The government has continually worked to maintain the integration of population concerns within overall development planning. The government regards population growth as an impediment to development and views the slow growth in per capita income as being due largely to the rapid population increase which continues to outpace the increases in the gross national product. The government perceives the current rate of population growth as unsatisfactory because it is too high. Mortality levels have dropped considerably, but the government still considers the situation with regard to mortality as unacceptable. In 1980 the UN estimated the infant mortality rate was 128.9 infant deaths/1000 live births for the 1975-80 period. The total fertility rate, as estimated by the UN, is reported to have dropped from 6.3 births per woman in 1960 to 6.0 in 1970 and 5.0 in 1980. The government has continuously indicated concern with fertility levels, perceiving the situation as unsatisfactory because its

    Full Text Available Background: Dyshormonogenetic goiter is one of the most common causes of hypothyroidism in children and adolescents in iodine nonendemic areas. The exact genotype-phenotypic correlations (GPCs and risk categorization of hypothyroid phenotypes of dyshormonogenetic mutations are largely speculative. The genetic studies in pediatric dyshormonogenesis are very sparse from Indian sub-continent. In this context, we analyzed the implications of TPO, NIS, and DUOX2 gene mutations in hypothyroid children with dyshormonogenetic hypothyroidism (DH from South India. Materials and Methods: This is interdisciplinary prospective study, we employed eight sets of primers and screened for 142 known single nucleotide polymorphisms in TPO, NIS, and DUOX2 genes. The subjects were children and adolescents with hypothyroidism due to dyshormonogenetic goiter. Congenital hypothyroidism, iodine deficiency, and Hashimoto's thyroiditis cases were excluded. Results: We detected nine mutations in 8/22 (36% children. All the mutations were observed in the intronic regions of NIS gene and none in TPO or DUOX2 genes. Except for bi-allelic, synonymous polymorphism of TPO gene in child number 14, all other mutations were heterozygous in nature. GPCs show that our mutations significantly expressed the phenotypic traits such as overt hypothyroidism, goiter, and existence of family history. Other phenotypic characters such as sex predilection, the age of onset and transitory nature of hypothyroidism were not significantly affected by these mutations. Conclusion: NIS gene mutations alone appears to be most prevalent mutations in DH among South Indian children and these mutations significantly influenced phenotypic expressions such as severity of hypothyroidism, goiter rates, and familial clustering.

    This article discusses the nature, magnitude, causes, and consequences of female child prostitution in India and offers measures for control and prevention of girl prostitution. Data are obtained from the 6-city study of prostitution and the author's own research. An estimated 85% of all prostitutes in Calcutta and Delhi entered the work at an early age. The numbers are rising. The promotion of tourism is linked with prostitution. Girl prostitutes are primarily located in low-middle income areas and business districts and are known by officials. Brothel keepers regularly recruit young girls. An estimated 33% of prostitutes are young girls. In Bangalore, Calcutta, Delhi, and Hyderabad, there are an estimated 10,000 girl prostitutes. UNICEF estimates about 300,000 child prostitutes. Girl prostitutes are grouped as common prostitutes, singers and dancers, call girls, religious prostitutes or devdasi, and caged brothel prostitutes. Religious prostitutes are mainly found in the South. Caged ones are found in Bombay. A little over 50% of prostitutes come from other countries, such as Nepal and Bangladesh. The girls tend to come from urban slums and poor rural areas. High prostitute supply regions include Andhra Pradesh, Karnataka, Maharashtra, Uttar Pradesh, Tamil Nadu, and West Bengel states. About 85% are Hindus, and about 66% are from scheduled castes and tribes. Bangalore and Bombay have a higher proportion of girl prostitutes. The causes of prostitution include ill treatment by parents, bad company, family prostitutes, social customs, inability to arrange marriage, lack of sex education, media, prior incest and rape, early marriage and desertion, lack of recreational facilities, ignorance, and acceptance of prostitution. Economic causes include poverty and economic distress. Psychological causes include desire for physical pleasure, greed, and dejection. Most enter involuntarily. A brief profile is given of the life of a prostitute.

    1997-10-01

    Coronary heart disease (CHD) is common in India and, recently, an increase in the incidence of CHD was reported from the South Indian state of Kerala. The traditional Indian diet is low in fat content. The high incidence of CHD in Indians is, therefore, in contrast to western studies that have correlated high fat, saturated fat and cholesterol intake to CHD. Consumption of coconut and coconut oil that contain high amounts of saturated fat and are thought to be strongly atherogenic, are believed to be one of the main reasons for the high incidence of CHD in Kerala. To explore this presumed link, we studied 32 CHD patients and 16 age and sex matched healthy controls. Consumption of coconut and coconut oil was found to be similar in both groups. The groups did not differ in the fat, saturated fat and cholesterol consumption. The results imply no specific role for coconut or coconut oil in the causation of CHD in the present set of Indian patients from Kerala. The exact reason for the high and increasing incidence of CHD among Indians is still unknown.

    To estimate the prevalence and severity of attachment loss in an urban population of South India and to determine related risk indicators. This population based cross sectional study used a subset of data from a large survey representative of urban population from Chennai city. The sample consisted of 900 subjects in the age range of 17 years to 87 years. Participants were interviewed using a structured proforma and subjected to a full mouth clinical examination of six sites per tooth. The prevalence of clinical attachment level (CAL) and association with various risk indicators was assessed. Out of the 900 subjects examined, 868 (96.4%) had CAL <5 mm and 32 (3.6%) had CAL ≥ 5 mm. Age, smoking, poor oral hygiene were found to be independent risk indicators for CAL (p<0.05). Smoking (pack years) was found to exhibit a dose response effect with CAL (Kendall's Tau coefficient = 0.098) (p<0.05). In this urban population, a low prevalence of CAL ≥ 5 mm was observed. Amongst the risk indicators evaluated, age, smoking and poor oral hygiene contribute significantly to attachment loss.

    The objective of this work is to elucidate various essential drugs in the Brazil, Russia, India, China and South Africa (BRICS) countries. It discusses the opportunities and challenges of the existing biotech infrastructure and the production of drugs and vaccines in member states of the BRICS. This research is based on a systematic literature review between the years 2000 and 2014 of documents retrieved from the databases Embase, PubMed/Medline, Global Health, and Google Scholar, and the websites of relevant international organizations, research institutions and philanthropic organizations. Findings vary from one member state to another. These include useful comparison between the BRICS countries in terms of pharmaceuticals expenditure versus total health expenditure, local manufacturing of drugs/vaccines using technology and know-how transferred from developed countries, and biotech entrepreneurial collaborations under the umbrella of the BRICS region. This study concludes by providing recommendations to support more of inter collaborations among the BRICS countries as well as between BRICS and many developing countries to shrink drug production costs. In addition, this collaboration would also culminate in reaching out to poor countries that are not able to provide their communities and patients with cost-effective essential medicines.

    Introduction Mucosal malignant melanoma of the anorectum is a rare and aggressive disease, in which early diagnosis is difficult. The prognosis remains extremely poor, irrespective of the treatment. We share our experience in treating this malignancy at our centre in South India. Methods This study describes a retrospective analysis of 31 cases of anorectal melanoma presented to our centre between January 2001 and December 2013. Results Twenty-two patients (71%) presented with metastasis and had a median overall survival of nine months. None of the 22 patients survived for two years. Nine patients (29%) had curative surgery, in the form of abdominoperineal resection (six patients), abdominoperineal resection with bilateral inguinal node dissection (one patient), abdominoperineal resection with liver resection (one patient) and posterior exenteration (one patient). In patients who underwent curative surgery, the median overall survival was 15 months and disease-free survival was nine months, with a two-year overall survival of 22%. Conclusions Anorectal melanoma is an aggressive disease with a poor prognosis. The majority of patients present with distant metastases. Prognosis depends on stage at presentation. Early diagnosis and surgical resection may improve the overall outcome. Newer modalities such as immunotherapy and targeted therapies such as anti-CTLA4 monoclonal antibody and anti-programmed cell death protein 1 monoclonal antibodies have radically changed the management of mucosal melanoma and may, in the future, improve the overall prognosis of anorectal melanoma.

    2018-02-01

    Main objective of the present paper is to examine the role of various parameterization schemes in simulating the evolution of mesoscale convective system (MCS) occurred over south-east India. Using the Weather Research and Forecasting (WRF) model, numerical experiments are conducted by considering various planetary boundary layer, microphysics, and cumulus parameterization schemes. Performances of different schemes are evaluated by examining boundary layer, reflectivity, and precipitation features of MCS using ground-based and satellite observations. Among various physical parameterization schemes, Mellor-Yamada-Janjic (MYJ) boundary layer scheme is able to produce deep boundary layer height by simulating warm temperatures necessary for storm initiation; Thompson (THM) microphysics scheme is capable to simulate the reflectivity by reasonable distribution of different hydrometeors during various stages of system; Betts-Miller-Janjic (BMJ) cumulus scheme is able to capture the precipitation by proper representation of convective instability associated with MCS. Present analysis suggests that MYJ, a local turbulent kinetic energy boundary layer scheme, which accounts strong vertical mixing; THM, a six-class hybrid moment microphysics scheme, which considers number concentration along with mixing ratio of rain hydrometeors; and BMJ, a closure cumulus scheme, which adjusts thermodynamic profiles based on climatological profiles might have contributed for better performance of respective model simulations. Numerical simulation carried out using the above combination of schemes is able to capture storm initiation, propagation, surface variations, thermodynamic structure, and precipitation features reasonably well. This study clearly demonstrates that the simulation of MCS characteristics is highly sensitive to the choice of parameterization schemes.

  14. Capacity, Debility and Differential Inclusion: The Politics of Microfinance in South India

    Vandana Chaudhry

    2018-02-01

    Full Text Available This article uses a critical disability lens to map how differential inclusion shatters the promise of democratizing capital in microfinance. Based on an ethnographic study of disability microfinance projects of the World Bank in India, it traces the dynamics of inclusion through the exclusion of debilitated bodies that cannot be capacitated within the neoliberal logic of entrepreneurship. A disability perspective brings into relief the pernicious ways that microfinance operates through webs of ableism, capitalism, and other axes of power and domination. It builds upon and contributes to the ongoing debates on microfinance as a form of neoliberal populism by showing what disability has to say about political futures amidst globalizing desires for inclusion, social mobility, and democratizing access to capital. Examining disability as a culturally-specific configuration of precarity and marginalization that is deepened by microfinance programs allows us to challenge the inclusionist claims of finance capital, and re-envision ethically and socially responsible frameworks. Generating culturally grounded knowledge on disability in the global south, this article also makes an important contribution to the field of disability studies, which scholars have argued remains implicated within the hegemony of 'scholarly colonialism' (Meekosha, 2011.

    Biopharmaceutical innovation has had a profound health and economic impact globally. Developed countries have traditionally been the source of most innovations as well as the destination for the resulting economic and health benefits. As a result, most prior research on this sector has focused on developed countries. This paper seeks to fill the gap in research on emerging markets by analyzing factors that influence innovative activity in the indigenous biopharmaceutical sectors of China, India, Brazil, and South Africa. Using qualitative research methodologies, this paper a) shows how biopharmaceutical innovation is taking place within the entrepreneurial sectors of these emerging markets, b) identifies common challenges that indigenous entrepreneurs face, c) highlights the key role played by the state, and d) reveals that the transition to innovation by companies in the emerging markets is characterized by increased global integration. It suggests that biopharmaceutical innovators in emerging markets are capitalizing on opportunities to participate in the drug development value chain and thus developing capabilities and relationships for competing globally both with and against established companies headquartered in developed countries.

    2009-12-01

    This paper offers an ethnography of the medicalization of matted locks of hair (jade) worn by female ecstatics in a South Indian devi (goddess) cult. These jade are taken by devotees of the devi Yellamma to be a manifestation of her presence in the bodies of women who enter possession states and give oracles. At her temples across the central Deccan Plateau, Yellamma women can be seen wearing heavy locks of matted hair anointed with turmeric, the color and healing properties of which are identified with this devi. Under a recent government-sponsored campaign, reformers cut jade and hand out packets of shampoo as a means of reforming the extended and illicit sexuality of these women. Associations between sexuality and hair practices have long preoccupied anthropologists interested in the relationship between the body and culture. In this paper, I draw on this literature and more than 2 years of field research to consider the encounter between biomedical and Shakta epistemologies of the body dramatized in these jade cutting campaigns. This effort to remake the body as a fit site and sign of modernity elaborates the postcolonial politics of sexuality, gender and religiosity in India.

    Full Text Available Self-medication is a common practice worldwide and the irrational use of drugs is a cause of concern. This study assessed the prevalence of self-medication among the medical students in South India. The data was analysed using SPSS version 11.5. A total of 440 students were included in the study. The prevalence of self-medication was 78.6%. A larger number of females were self-medicating (81.2% than males (75.3%. The majority of the students self-medicated because of the illness being too trivial for consultation (70.5%. Antipyretics were most commonly self-medicated by the participants (74.8%. Only 47% of the participants opined that self-medication was a part of self-care and it needs to be encouraged. 39.3% of the participants perceived that the supply of medicine without prescription by the pharmacist can prevent the growing trend of self-medication. Easy availability and accessibility to health care facilities remains the cornerstone for reducing the practice of self-medication.

    Adequate antenatal counseling combined with postnatal lactation support is likely to improve exclusive breastfeeding rates. To assess the impact of a postnatal video based health education program in promoting exclusive breastfeeding among primiparous mothers. This interventional study was done in a tertiary care teaching hospital, south India. Primiparous mothers in one postnatal ward (group A) received routine lactation counseling. A similar group of primiparous mothers in another postnatal ward (group B) were administered a video based health education program on exclusive breastfeeding in the local language Tamil in addition to the routine lactation counseling. The exclusive breastfeeding rates of these two groups of mothers were compared. Their knowledge and perceptions after intervention were also compared using a pretested questionnaire. Among 878 primiparous mothers, 94% fed colostrum and 43% initiated breastfeeding within one hour of delivery. Correct attachment was noted with 96% and 13% had lactation issues. Group B had marginally better exclusive breastfeeding rate at six months but not statistically significant. Mothers in group B had a statistically significant better knowledge score post-intervention compared to those in Group A. Use of gripe water was more in group A compared to group B. The video based health education program when combined with routine lactation counseling improved the knowledge regarding exclusive breastfeeding among postnatal primiparous mothers better than with routine lactation counseling alone. However, both interventions had similar effect on exclusive breastfeeding rate at six months.

    Elephant endotheliotropic herpesviruses (EEHVs) can cause fatal hemorrhagic disease in Asian (Elephas maximus) and African (Loxodonta africana) elephants. Of the seven known EEHV species, EEHV1 is recognized as the most common cause of hemorrhagic disease among Asian elephants in human care worldwide. Recent data collected from ex situ Asian elephants located in multiple North American and European institutions suggest that subclinical EEHV1 infection is common in this population of elephants. Although fatal EEHV1-associated hemorrhagic disease has been reported in range countries, data are lacking regarding the prevalence of subclinical EEHV infections among in situ Asian elephants. We used previously validated EEHV-specific quantitative real-time PCR assays to detect subclinical EEHV infection in three regionally distinct Asian elephant cohorts, totaling 46 in situ elephants in South India, during October and November 2011. Using DNA prepared from trunk washes, we detected EEHV1, EEHV3/4, and EEHV5 at frequencies of 7, 9, and 20% respectively. None of the trunk washes was positive for EEHV2 or 6. At least one EEHV species was detectable in 35% (16/46) of the samples that were screened. These data suggest that subclinical EEHV infection among in situ Asian elephants occurs and that Asian elephants may be natural hosts for EEHV1, EEHV3 or 4, and EEHV5, but not EEHV2 and EEHV6. The methodology described in this study provides a foundation for further studies to determine prevalences of EEHV infection in Asian elephants throughout the world.

    2010-12-01

    The state of Kerala, south India, has particularly high prevalence rates for cardiovascular disease (20%, Sugathan, Soman and Sankaranarayanan 2008) and Type II diabetes (16.3%, Kutty, Joseph, and Soman 1999). Although so-called 'lifestyle' diseases can be prevented and symptoms controlled by diet, exercise, and medicines, heart disease and diabetes have become the most common causes of suffering, disability and death. This article explores the social dynamics transforming consumer lifestyles as increased food consumption, reduced physical activity and social stress contribute to the burden of cardiovascular disease (CVD). It examines the centrality of food to ideas of the 'good life', to nurture social relationships and strengthen weak modern bodies, as the principle source of embodied pleasure and health. It explores the micro and macro politics of eating and feasting, limiting the extent to which 'individuals' (can) control food habits. Thus, despite widespread recognition of the relationship between diet, exercise and heart disease, the flow of food, the immediacy of pleasure, and associations between appetite and health override latent concerns about the negative impacts of dietary excesses on long-term health and chronic illness. Findings are discussed to highlight the inherent limitations of public health interventions focusing on education and individual choice.

    Drainage morphometry provides quantitative description of the drainage system which is an important aspect of the characterisation of watersheds. Chalakudi River is one of the important rivers of the South India which has attracted attention of many environmental scientists recently because of the proposed Athirapally Hydel Project across the river. SRTM (Shuttle Radar Topographic Mission) data were used for preparing DEM (Digital Elevation Model), Aspect Map and Slope Map. Geographical Information System (GIS) was used for the evaluation of linear, areal and relief aspects of morphometric parameters. The study reveals that the terrain exhibits dentritic and trellis pattern of drainage. The Chalakudi River Basin has a total area of 1,448.73 km2 and is designated as seventh-order basin. The drainage density of the basin is estimated as 2.54 and the lower-order streams mostly dominate the basin. The high basin relief indicates high runoff and sediment transport. The elongation ratio of the Chalakudi Basin is estimated as 0.48 and indicates that the shape of the basin is elongated. The development of stream segments in the basin area is more or less effected by rainfall. Relief ratio indicates that the discharge capability of watershed is very high and the groundwater potential is meagre. The low value of drainage density in spite of mountainous relief indicates that the area is covered by dense vegetation and resistant rocks permeated by fractures and joints. These studies are helpful in watershed development planning and wise utilization of natural resources.

    Full Text Available Background: There was a recent epidemic of chikungunya (CKG in Calicut and other northern districts of Kerala, South India, affecting thousands of people. Aims: To study the cutaneous manifestations of CKG and to have a serological and histopathological correlation. Methods: A total of 162 patients (63 males and 99 females with cutaneous manifestations of CKG were enrolled in the study and serological confirmation was done with capture IgM ELISA for CKG. Skin biopsy was done in all representative cases. Results: Cutaneous manifestations were found more in females. There were 23 children, the youngest being 39 days old. Generalized erythematous macular rash was the most common finding. Vesicles and bullae were also common especially in infants. Localized erythema of the nose and pinnae, erythema and swelling of the pre existing scars and striae and toxic epidermal necrolysis-like lesions sparing mucosae were the other interesting findings. Different types of pigmentation were observed with a striking nose pigmentation in a large number of patients, by looking at which even a retrospective diagnosis of CKG could be made. Hence we suggest this peculiar pigmentation may be called "chik sign". There was flare up of existing dermatoses like psoriasis, lichen planus and unmasking of Hansen′s disease with type 1 reaction. Serological tests were positive in 97%. Some hitherto unreported histopathologic findings like melanophages in the erythematous rashes were observed. Conclusion: A spectrum of cutaneous manifestations of CKG with a wide variety of unusual presentations with confirmed serological and histopathological evidence was encountered.

    An urban population in a township in south India was screened for diabetes with an oral glucose tolerance test, every fifth person aged 20 and over registered at the local iron ore company's hospital being screened. Of 678 people (346 men and 332 women) who were tested, 34 (5%; 20 men and 14 women) had diabetes and 14 (2%; 8 men and 7 women) had impaired glucose tolerance. Thirteen subjects were already known to be diabetic. Diabetes was present in 21% (37/179) of people aged over 40. The peak prevalence (41%; 7/17) was in the group aged 55-64. A family history of diabetes was present in 16 of the 34 subjects with diabetes and nine of the 15 with impaired glucose tolerance. Diabetes was significantly related to obesity in women but not in men (57% (8/14) v 5% (1/20)). The plasma glucose concentration two hours after glucose loading was correlated to body mass index, age, and income in both sexes. The prevalence of diabetes was significantly higher in subjects whose income was above the mean. When the overall prevalence of diabetes was adjusted to the age distribution of the Indians living in Southall, London, and in Fiji it increased to 10% and 9%, respectively. The prevalence of diabetes is high among urban Indians and is comparable with the high prevalence seen in migrant Indian populations. PMID:3139221

    This article explores quality-of-life aspects among gay, lesbian, bisexual, and straight male and female students in Havana (Cuba), Tromsø (Norway), Hisar (India), and Cape Town (South Africa). In the period 2004-2005, a questionnaire survey on sexuality, happiness, and life satisfaction was undertaken among 339 students from the University of Havana, 144 students from the University of Tromsø, 200 students from Guru Jambheswar University, and 189 students from the University of the Western Cape. The majority of the participants were straight and, in Hisar and Cape Town, few of those who regarded themselves as gay/lesbian/bisexual had engaged in sex with a person of the same gender. In all cities, straight men and women scored higher than gay, lesbian, and bisexual persons on the quality-of-life measures. Quality of life among gay/bisexual men and lesbian/bisexual women was higher in cultures with accepting attitudes toward homosexuality than in cultures with restrictive attitudes.

    To find out the prevalence and causes of hearing impairment among children of school-entry age, in rural areas of coastal south India. The study adopted the World Health Organization (WHO) guidelines viz., "The Prevalence of Ear and Hearing Disorders Protocol". A total of 855 children studying in the first year of school were examined using a Portable Pure Tone Audiometer and an Otoscope. Children with hearing impairment were re-examined to find out the type of hearing impairment. Mothers of all children were interviewed in their homes, in order to obtain details of socio-economic status, family history and history of consanguinity. Hearing impairment was detected in 102 children (11.9%) and impacted wax was found to be the most common cause of hearing impairment (86.3%). On re-testing, it was predominantly conductive hearing impairment (81.6%) observed among 74 of these children. The prevalence of hearing impairment was significantly lower among children belonging to high socio-economic status (P=0.0036). Hearing impairment and preventable ear diseases were found to be important health problems among children of school-entry age group in this region. Regular screening of children of school-entry age will ensure that children begin their school-life without this disability.

    Full Text Available Abstract Biopharmaceutical innovation has had a profound health and economic impact globally. Developed countries have traditionally been the source of most innovations as well as the destination for the resulting economic and health benefits. As a result, most prior research on this sector has focused on developed countries. This paper seeks to fill the gap in research on emerging markets by analyzing factors that influence innovative activity in the indigenous biopharmaceutical sectors of China, India, Brazil, and South Africa. Using qualitative research methodologies, this paper a shows how biopharmaceutical innovation is taking place within the entrepreneurial sectors of these emerging markets, b identifies common challenges that indigenous entrepreneurs face, c highlights the key role played by the state, and d reveals that the transition to innovation by companies in the emerging markets is characterized by increased global integration. It suggests that biopharmaceutical innovators in emerging markets are capitalizing on opportunities to participate in the drug development value chain and thus developing capabilities and relationships for competing globally both with and against established companies headquartered in developed countries.

    This report examines the use of coal for power generation and major industrial applications in the growing dynamic economies of China, India and South Africa, each of which relies heavily on coal for energy production. There are some similarities in the uses and technologies deployed in these three countries, but there are also differences. The use of some technologies is widespread, whereas others have developed to meet more specific local requirements, hence their geographical application is more limited. These similarities and differences are examined and compared with world best practice. In all three countries, as in many others, there are coal-consuming plants where performance and efficiency is on a par with the best in the world. However, such application is not necessarily universal and there are often big differences between the best and worst performers. These differences are generally greater than in OECD nations. Through existing collaborations with OECD industry, modern technologies are already being introduced into these three countries. However, in order to improve effectiveness of a particular sector as a whole, in some cases, greater replacement of the existing infrastructure is required, and there are parts that would benefit from greater penetration of world best practice. 90 refs., 22 figs., 16 tabs.

    Full Text Available PURPOSE: To identify the specific microbial pathogens responsible for corneal ulceration in South India and compare these profiles with other series. METHODS: All patients with infectious keratitis who presented between 20th September 1999 and 31st March 2001 were evaluated. They were examined by slit-lamp biomicroscopy and corneal scrapings were performed for cultures and smears by using standard protocols. RESULTS: In the 18 months period, 1618 patients with corneal ulcerations were evaluated. Corneal cultures were found to be positive in 1126(69.59% patients. Of the 1618 patients, 566(34.98% had bacterial growth, 522(32.26% had fungal growth, 30(1.85% had mixed bacterial and fungal growth, 8(0.49% had Acanthamoeba species growth and the remaining 492(30.41% were found to be culture negative. The predominant bacterial pathogen isolated was Streptococcus pneumoniae representing 41.85%, followed by Pseudomonas aeruginosa 21.25%. The predominant fungal pathogens isolated were Fusarium species (45.85% followed by Aspergillus species (24.37%. CONCLUSIONS: Bacterial and fungal infections occurred almost with equal frequency, the predominant bacterial and fungal species isolated being Streptococcus pneumoniae and Fusarium species respectively. The findings of our study show that there is a region wise variation in the predominance of corneal pathogens. This has an important public health implication for the initiation of therapy.

    China, India, Brazil and South Africa contain 40% of the global population and are key emerging economies. All these countries have a policy commitment to universal health coverage with an emphasis on primary health care. The primary care doctor is a key part of the health workforce, and this article, which is based on two workshops at the 2014 Towards Unity For Health Conference in Fortaleza, Brazil, compares and reflects on the roles and training of primary care doctors in these four countries. Key themes to emerge were the need for the primary care doctor to function in support of a primary care team that provides community-orientated and first-contact care. This necessitates task-shifting and an openness to adapt one's role in line with the needs of the team and community. Beyond clinical competence, the primary care doctor may need to be a change agent, critical thinker, capability builder, collaborator and community advocate. Postgraduate training is important as well as up-skilling the existing workforce. There is a tension between training doctors to be community-orientated versus filling the procedural skills gaps at the facility level. In training, there is a need to plan postgraduate education at scale and reform the system to provide suitable incentives for doctors to choose this as a career path. Exposure should start at the undergraduate level. Learning outcomes should be socially accountable to the needs of the country and local communities, and graduates should be person-centred comprehensive generalists.

    The objective of this work is to elucidate various essential drugs in the Brazil, Russia, India, China and South Africa (BRICS) countries. It discusses the opportunities and challenges of the existing biotech infrastructure and the production of drugs and vaccines in member states of the BRICS. This research is based on a systematic literature review between the years 2000 and 2014 of documents retrieved from the databases Embase, PubMed/Medline, Global Health, and Google Scholar, and the websites of relevant international organizations, research institutions and philanthropic organizations. Findings vary from one member state to another. These include useful comparison between the BRICS countries in terms of pharmaceuticals expenditure versus total health expenditure, local manufacturing of drugs/vaccines using technology and know-how transferred from developed countries, and biotech entrepreneurial collaborations under the umbrella of the BRICS region. This study concludes by providing recommendations to support more of inter collaborations among the BRICS countries as well as between BRICS and many developing countries to shrink drug production costs. In addition, this collaboration would also culminate in reaching out to poor countries that are not able to provide their communities and patients with cost-effective essential medicines.

    Self-medication is a common practice worldwide and the irrational use of drugs is a cause of concern. This study assessed the prevalence of self-medication among the medical students in South India. The data was analysed using SPSS version 11.5. A total of 440 students were included in the study. The prevalence of self-medication was 78.6%. A larger number of females were self-medicating (81.2%) than males (75.3%). The majority of the students self-medicated because of the illness being too trivial for consultation (70.5%). Antipyretics were most commonly self-medicated by the participants (74.8%). Only 47% of the participants opined that self-medication was a part of self-care and it needs to be encouraged. 39.3% of the participants perceived that the supply of medicine without prescription by the pharmacist can prevent the growing trend of self-medication. Easy availability and accessibility to health care facilities remains the cornerstone for reducing the practice of self-medication.

    Post-partum depression, although heterogeneous, is often considered a medical disease when viewed from the biomedical perspective. However, recent reports from the Indian subcontinent have documented psychosocial causal factors. This study employed qualitative methodology in a representative sample of women in rural South India. Women in the post-partum period were assessed using the Tamil versions of the Short Explanatory Model Interview, the Edinburgh Postnatal Depression Scale and a semi-structured interview to diagnose ICD 10 depression. Socio-demographic and clinical details were also recorded. Some 137 women were recruited and assessed, of these, 26.3% were diagnosed to have post-partum depression. The following factors were associated with post-partum depression after adjusting for age and education: age less than 20 or over 30 years, schooling less than five years, thoughts of aborting current pregnancy, unhappy marriage, physical abuse during current pregnancy and after childbirth, husband's use of alcohol, girl child delivered in the absence of living boys and a preference for a boy, low birth weight, and a family history of depression. Post-partum depression was also associated with an increased number of causal models of illness, a number of non-medical models, treatment models and non-medical treatment models. Many social and cultural factors have a major impact on post-partum depression. Post-partum depression, when viewed from a biomedical framework, fails to acknowledge the role of context in the production of emotional distress in the post-partum period.

    Malaria caused by the protozoan parasite Plasmodium falciparum, is a major health problem of the developing world. In the present study medicinal plants from Eastern Ghats of South India have been extracted with ethyl acetate and assayed for growth inhibition of asexual erythrocytic stages of chloroquine (CQ)-sensitive (3D7) and (CQ)-resistant (INDO) strains of P. falciparum in culture using the fluorescence-based SYBR Green I assay. Studied extracts showed a spectrum of antiplasmodial activities ranging from (a) very good (IC(50)10-15 μg/mL: Ficus religiosa and Murraya koenigii); (c) moderate (IC(50)>15-25 μg/mL: Ficus benghalensis); (d) poor activity (IC(50)>25-60 μg/mL) and (e) inactive (IC(50)>60 μg/mL). Resistance indices ranging from 0.78 to 1.28 suggest that some of these extracts had equal promise against the CQ resistant INDO strain of P. falciparum. Cytotoxicity assessment of the extracts against HeLa cell line using MTT assay revealed that the selectivity indices in the range of 3-15 suggesting a good margin of safety.

    The levels of 17 organochlorine pesticides residues (OCPs) in surface water and sediments from Tamiraparani river basin, South India were investigated to evaluate their potential pollution and risk impacts. A total of 96 surface water and sediment samples at 12 sampling stations were collected along the river in four seasons during 2008-2009. The ΣOCP concentrations in surface water and sediments were in the range of 0.1 to 79.9 ng l(-1) and 0.12 to 3,938.7 ng g(-1) dry weight (dw), respectively. Among the OCPs, the levels of dichlorodiphenyltrichloroethanes (DDTs), aldrin, dieldrin, cis-chlordane, trans-chlordane, and mirex were dominant in the sediments. The dominant OCPs in water samples are heptachlor, o,p'-DDE, dieldrin, o,p'-DDD, and mirex, which show different source of contamination pattern among sampling seasons. The distribution pattern of DDTs, hexachlorocyclohexane, and other OCPs in the present study shows heterogenic nature of nonpoint source of pollution. Notable contamination of water and sediment sample that was observed in upstream (S2) 58 ng l(-1) and downstream (S11) 1,693 ng g(-1) dw explains agricultural and municipal outfalls, whereas frequent damming effect reduces the concentration level in the midstream. The overall spatial-temporal distribution pattern of ΣOCP residues are illustrated by GIS package.

    Full Text Available Human behaviour normally depends on the environment of the incident and the time of its occurrence. The behaviour of people depends on many factors and these behaviour traits are an important aspect in the Library and Information Science (LIS field. Hence in this paper an attempt has been made to examine the behaviour traits of LIS students in South India. Out of 400 questionnaires distributed 367 have responded and the response rate is 91.75%. In this survey three aspects comprising student behaviour have been analysed such as Work Environment, Natural Environment, and Social Environment. In the case of Work Environment the respondents were grouped as Workaholic, Impatience, Achievement oriented, Rash nature, and Punctuality. Further, in respect to Natural environment, the respondents are grouped as Complacent, Patience, Easygoing, and Relaxed. Last, the respondents were grouped in the Social Environment as Balancing nature, Magnanimity, Naturalistic, Assertive nature, Dependency, Lucrative, Lonely nature, and Time Based personality. Finally the authors conclude that LIS students need to possess these qualities and behaviours to work in different environments.

    Objectives To provide susceptibility data for community-acquired respiratory tract isolates of Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae and Moraxella catarrhalis collected in 2012–14 from four Asian countries. Methods MICs were determined using Etest® for all antibiotics except erythromycin, which was evaluated by disc diffusion. Susceptibility was assessed using CLSI, EUCAST and pharmacokinetic/pharmacodynamic (PK/PD) breakpoints. For macrolide/clindamycin interpretation, breakpoints were adjusted for incubation in CO2 where available. Results Susceptibility of S. pneumoniae was generally lower in South Korea than in other countries. Penicillin susceptibility assessed using CLSI oral or EUCAST breakpoints ranged from 21.2% in South Korea to 63.8% in Singapore. In contrast, susceptibility using CLSI intravenous breakpoints was much higher, at 79% in South Korea and ∼95% or higher elsewhere. Macrolide susceptibility was ∼20% in South Korea and ∼50%–60% elsewhere. Among S. pyogenes isolates (India only), erythromycin susceptibility (∼20%) was lowest of the antibiotics tested. In H. influenzae antibiotic susceptibility was high except for ampicillin, where susceptibility ranged from 16.7% in South Korea to 91.1% in India. South Korea also had a high percentage (18.1%) of β-lactamase-negative ampicillin-resistant isolates. Amoxicillin/clavulanic acid susceptibility for each pathogen (PK/PD high dose) was between 93% and 100% in all countries except for H. influenzae in South Korea (62.5%). Conclusions Use of EUCAST versus CLSI breakpoints had profound differences for cefaclor, cefuroxime and ofloxacin, with EUCAST showing lower susceptibility. There was considerable variability in susceptibility among countries in the same region. Thus, continued surveillance is necessary to track future changes in antibiotic resistance. PMID:27048580

    Full Text Available Introduction: Reproductive tract infections including sexually transmitted infections (RTI/STIs are problems of public health priority compromising the reproductive health of women especially in developing countries. The problem is compounded by the poor health care seeking behaviour among women due to lack of awareness and sociocultural factors. Objectives: This study is an attempt to assess the health care seeking behaviour of women reporting RTI symptoms in a rural area of Tamil Nadu state of India and to examine the association of background sociodemographic characteristics with Health care seeking behaviour. Methodology: This was a cross sectional, descriptive study conducted between March to November 2011, among married women aged 18-45 years in a rural area of Kancheepuram district, Tamil Nadu in India. The required sample size was chosen by simple random sampling. The participants were administered a standardized, semi-structured schedule. Results: 520 women participated in the study. 173 women (33.3% of women reported experiencing symptoms of RTI/STI in the past 12 months. Only 51.45% of those who had RTI/STI symptoms sought health care. Private health care facility was preferred by nearly two-thirds. The health care seeking behaviour showed significant association with age group of women, religion, occupational status, type of family and socioeconomic status. Conclusion: There is a need for increasing awareness among women regarding RTI/STIs and their sequelae. Targeted health education programmes should be necessary to improve health care seeking among women.

This cross-sectional study was done to describe the occurrence of metabolic syndrome, diabetes mellitus, and insulin resistance in HIV-positive patients in a tertiary referral center in South India. A total of 60 patients who had HIV infection for 12 months or more were enrolled in the study. Of these, 30 patients were antiretroviral therapy (ART-naïve, and 30 were treated with ART. Biochemical estimations (fasting blood glucose, 75 g oral glucose tolerance test, lipid profile, and fasting insulin and anthropometric measurements (height, weight, and waist circumference were performed for each patient. Metabolic syndrome was diagnosed using National Cholesterol Education Program–Adult Treatment Plan III criteria, and insulin resistance was calculated applying the homeostasis model assessment method. Diabetes mellitus, impaired fasting glycemia, and impaired glucose tolerance were diagnosed based on American Diabetes Association criteria. A high prevalence of metabolic syndrome was observed in patients with HIV (16/60, and was more prevalent in the ART-treated group (13/30; P = 0.028. Similarly, insulin resistance was also noted to be high (24/60, and of these patients, 15 were on ART. Seventy-five percent of patients with metabolic syndrome had insulin resistance. Diabetes was diagnosed in one patient who was ART-naïve and in six patients who were on ART.

    THE BIOLOGICAL BEHAVIOR OF ENDOMETRIAL CARCINOMA DIFFERS IN EPIDEMIOLOGY, PRESENTATION, AND PROGNOSIS, SUGGESTING THAT THERE ARE TWO FUNDAMENTALLY DIFFERENT PATHOGENIC TYPES OF DISEASE: type I (estrogen related, endometrioid type) and type II (non-estrogen related, non-endometrioid type). Untreated hyperplasia can develop into an endometrioid type of adenocarcinoma, hence, it is important to recognize the former type. In contrast to cervical cancers, there are limited studies with respect to the biology of hyperplastic lesions documented from India. This was a 16-year retrospective study, carried out to determine the nature and outcome of proliferative lesions of the endometrium in a referral center from south India. A histopathological diagnosis of the endometrial hyperplasia, polyp, and carcinoma, on endometrial biopsy and hysterectomy specimens, over a 16 year period (1983 to 1999), were recorded in a computer and the case slides were reviewed. Using the computer software Foxpro, the patients who had come more than once for a subsequent or previous biopsy were identified. An attempt was made to look for progression, regression or a static nature of the lesion in the follow-up cases. A total of 1778 cases were studied, and only 74 patients with endometrial hyperplasia and five cases of benign endometrial polyp had follow-up endometrial histopathology. Hyperplasia cases included 59 cases of simple hyperplasia, 10 cases of complex hyperplasia without atypia, and five cases with atypia. The predominant age for patients with all types of hyperplasias was 41 - 50 years. Progression to a higher grade was seen in 8.10%, regression to a lower grade was seen in 9.45%, lesions reverted to a normal pattern in 10.81% cases, and lesions persisted in 70.27% of the cases. A mixed pattern was seen in 54 cases, with predominant coexistent lesion being simple and complex hyperplasia without atypia. The fate of the hyperplastic lesion of the endometrium showed a varied pattern

    While community mobilization has been widely endorsed as an important component of HIV prevention among vulnerable populations such as female sex workers (FSWs), there is uncertainty as to the mechanism through which it impacts upon HIV risk. We explored the hypothesis that individual and collective empowerment of FSW is an outcome of community mobilization, and we examined the means through which HIV risk and vulnerability reduction as well as personal and social transformation are achieved. This study was conducted in five districts in south India, where community mobilization programs are implemented as part of the Avahan program (India AIDS Initiative) of the Bill & Melinda Gates Foundation. We used a theoretically derived "integrated empowerment framework" to conduct a secondary analysis of a representative behavioural tracking survey conducted among 1,750 FSWs. We explored the associations between involvement with community mobilization programs, self-reported empowerment (defined as three domains including power within to represent self-esteem and confidence, power with as a measure of collective identity and solidarity, and power over as access to social entitlements, which were created using Principal Components analysis), and outcomes of HIV risk reduction and social transformation. In multivariate analysis, we found that engagement with HIV programs and community mobilization activities was associated with the domains of empowerment. Power within and power with were positively associated with more program contact (p personal transformation" in terms of self-efficacy for condom and health service use (p Collective empowerment (power with others) was most strongly associated with "social transformation" variables including higher autonomy and reduced violence and coercion, particularly in districts with programs of longer duration (p power with others (p power within was associated with more condom use with regular partners (p collectively.

    Protein-energy malnutrition is a major health problem contributing to the burden of disease in developing countries. The aim of this study was to assess the incidence of, and risk factors for, malnutrition among school-going children in south India. A total of 2496 children aged 5-7 years from rural and urban areas of south India were recruited in 1982 and followed up for malnutrition over a period of 9 years. Their body heights and weights were measured every six months and socio-demographic factors such as mother's education and father's education and relevant household characteristics and hygiene practices collected. Body mass index and height-for-age z-scores were used to determine children's levels of underweight and stunting, respectively, classified as normal, mild/moderate or severe. Risk factor analysis was done for pre-pubertal ages only using Generalized Estimating Equations with cumulative odds assumption. There was a significant difference between male and female children in the incidence of severe underweight and stunting (6.4% and 4.2% respectively). Children in households with no separate kitchen had 1.3 (1.0-1.6) times higher odds of being severely underweight (p=0.044) compared with those with a kitchen. Children without a toilet facility had significantly higher odds of severe underweight compared with those who did. Children with illiterate parents had higher odds of severe stunting than those with literate parents. In conclusion, the prevalence of malnutrition among these south Indian children has not changed over the years, and the incidence of severe malnutrition was highest in children when they were at pubertal age. The risk factors for stunting were mostly poverty-related, and those for underweight were mostly hygiene-related. Adolescent children in south India should be screened periodically at school for malnutrition and provided with nutritional intervention if necessary.

    Human leukocyte antigen (HLA) genes have been implicated in cervical cancer in several populations. To study the predispositions of HLA alleles/haplotypes with cervical cancer. Clinically diagnosed and PAP smear confirmed cervical cancer patients (n 48) and age matched controls (n 47) were genotyped for HLA-A,-B,-DRB1* and DQB1* alleles by PCR-SSP methods. The frequencies of alleles DRB1*04 (OR=2.57), DRB1*15 (OR=2.04), DQB1*0301 (OR=4.91), DQB1*0601 (OR=2.21), B*15 (OR=13.03) and B*07 (OR=6.23) were higher in cervical cancer patients than in the controls. The frequencies of alleles DRB1*10 (OR=0.22) and B*35 (OR=0.19) were decreased. Strong disease associations were observed for haplotypes DRB1*15-DQB1*0601 (OR=6.56; HLA-C* typing of 8 patients who possessed a unique three locus haplotype 'A*11-B*07-DRB1*04' (8/48; 16.66%; OR=6.51; cancer. Strong susceptible associations were documented for HLA alleles B*15, B*07, DRB1*04, DRB1*15, DQB1*0301, DQB1*0601 and haplotypes DRB1*15-DQB1*0601 and DRB1*14-DQB1*0501. Further, protective associations were evidenced for alleles B*35 and DRB1*10 and haplotypes A*11-B*35 and DRB1*10-DQB1*0501 with cervical cancer in South India.

    Full Text Available Stunting or reduced linear growth is very prevalent in low-income countries. Recent studies have demonstrated a causal relationship between alterations in the gut microbiome and moderate or severe acute malnutrition in children in these countries. However, there have been no primary longitudinal studies comparing the intestinal microbiota of persistently stunted children to that of non-stunted children in the same community. In this pilot study, we characterized gut microbial community composition and diversity of the fecal microbiota of 10 children with low birth weight and persistent stunting (cases and 10 children with normal birth weight and no stunting (controls from a birth cohort every 3 months up to 2 years of age in a slum community in south India. There was an increase in diversity indices (P <0.0001 with increasing age in all children. However, there were no differences in diversity indices or in the rates of their increase with increasing age between cases and controls. The percent relative abundance of the Bacteroidetes phylum was higher in stunted compared to control children at 12 months of age (P = 0.043. There was an increase in the relative abundance of this phylum with increasing age in all children (P = 0.0380 with no difference in the rate of increase between cases and controls. There was a decrease in the relative abundance of Proteobacteria (P = 0.0004 and Actinobacteria (P = 0.0489 with increasing age in cases. The microbiota of control children was enriched in probiotic species Bifidobacterium longum and Lactobacillus mucosae, whereas that of stunted children was enriched in inflammogenic taxa including those in the Desulfovibrio genus and Campylobacterales order. Larger, longitudinal studies on the compositional and functional maturation of the microbiome in children are needed.

    The human population residing in the monazite bearing high level natural background radiation (HLNBR) areas of Kerala, along the South-West coast of India provides unique opportunities of assessing directly in man, the health effects of chronic low-level radiation exposure. The per capita dose received by this population is nearly four times the normal background radiation level. While this is the average dose, the radiation levels prevailing in these HLNBR areas are in the range of 1 to over 35 mGy per year. Chromosomal aberration studies in the lymphocytes of newborns and adults from these areas have been in progress for two decades. So far, 4156 newborn babies from HLNBR and 7321 from normal background radiation (NBR) areas have been screened for the incidence of chromosomal aberrations (dicentrics and rings). The mean frequency of dicentrics and rings did not show any significant difference between the newborns in the control and the HLNBRA population. Assessment of the frequency of micronuclei in cytochalasin-B blocked binucleated lymphocytes of 49 newborns from control areas and 131 newborns from radioactive areas also showed similar values. While an age-dependent increase in chromosome aberration frequency was observed in the adult samples from control and the study areas, the regression analysis of the data indicated a marginally higher slope for the samples from HLNBRA. Karyotype anomalies recorded so far among the newborns have not revealed any significant difference in the incidence of numerical (including Down syndrome) and structural alterations between the control and the exposed populations. A noteworthy observation, herein reported for the first time from any HLNBR area is that there is no discernible increase in the incidence of micronuclei and chromosomal aberrations in the peripheral lymphocytes of newborn babies hailing from HLNBR areas, where their ancestral generations have lived for several hundreds of years.

    Fishing is an occupation associated with uneven diet, strain, drunkenness, tobacco use, and deleterious habits. The physical state of laborers on a large scale will also be influenced by conditions at their work site. Oral mucosal lesions can occur as a result of infections, local shock or infuriation, systemic diseases, and uncontrolled usage of tobacco, betel quid, and alcohol. The aim of the present study is to assess the prevalence of deleterious oral habits and oral mucosal lesions among fishermen population of Mahe, South India. The study population consists of 362 fishermen aged between 15 and 54. The questionnaire consisted of questions on personal data, and information related to the subjects' oral habits were collected by the interview. The World Health Organization (WHO) Oral Health Assessment Form was designed for the assessment of oral mucosal lesions. Among the 362 fishermen, 266 (73.48%) were males and 96 (26.52%) were females. The overall prevalence of smoking, alcohol consumption, and gutka chewing was found to be 24.3, 48.85, and 32.4% respectively. Smokeless tobacco (32.4%) was the most prevalent habit followed by smoking tobacco (24.3%). The prevalence of oral mucosal lesions was 14.9%. There is a statistically significant association between age groups and habits considered. Findings of the present study suggest that oral health condition of the fisherfolk community was relatively poor, with high habit prevalence and oral mucosal lesions. This epi-demiological study has provided baseline data to plan further research in this area. Low socioeconomic status, strenuous working hours, inadequate diet and nutrition intake, stress, and use of tobacco and alcohol act as contributing factors for ill health and oral diseases. It is a challenging population to the clinician to identify and treat them.

    Childhood obesity and overweight is a global epidemics and has been increasing in the developing countries. Childhood obesity is linked with increased mortality and morbidity independent of adult obesity. Declining physical activity, access to junk food and parenting style are the major determinants of overweight in children. Thus, there is a need for increasing the physical activity of children, educating the parents as well as the children on lifestyle modification. This can be achieved through implementation of multicomponent intervention. To evaluate the effectiveness of multicomponent intervention on improving the lifestyle practices, reducing the body fat and improving the self esteem of obese children from selected schools of Udupi District, South India. A sample of 120 obese children were enrolled for multicomponent intervention. The components of multicomponent intervention were: education provided to the obese children on lifestyle modification, education of the parents and increasing the physical education activity of these children in the form of aerobics under the supervision of physical education teacher. There was an attrition of 25% in the intervention group. Thus the final sample in the intervention group was 90. Total sample of 131 overweight/ obese children enrolled as controls. There was an attrition of 20.61% in the control group. Thus, the final sample in the control group was 104. Intervention group received the multicomponent intervention for six month. Mixed Method Repeated measures Ananlysis of Variance (ANOVA) was applied for analysis of data. Results indicated that the intervention was effective in reducing the Body Mass Index (BMI), triceps, biceps, subscapular skin fold thickness of obese children. The intervention was also effective in improving the lifestyle practices and self-esteem of obese children. Overweight/obese children need to control diet and perform vigorous exercise at least for 20 minutes a day to reduce the excess fat

    Full Text Available BACKGROUND: Weak health systems in low- and middle-income countries are recognized as the major constraint in responding to the rising burden of chronic conditions. Despite recognition by global actors for the need for research on health systems, little attention has been given to the role played by local health systems. We aim to analyze a mixed local health system to identify the main challenges in delivering quality care for diabetes mellitus type 2. METHODS: We used the health system dynamics framework to analyze a health system in KG Halli, a poor urban neighborhood in South India. We conducted semi-structured interviews with healthcare providers located in and around the neighborhood who provide care to diabetes patients: three specialist and 13 non-specialist doctors, two pharmacists, and one laboratory technician. Observations at the health facilities were recorded in a field diary. Data were analyzed through thematic analysis. RESULT: There is a lack of functional referral systems and a considerable overlap in provision of outpatient care for diabetes across the different levels of healthcare services in KG Halli. Inadequate use of patients' medical records and lack of standard treatment protocols affect clinical decision-making. The poor regulation of the private sector, poor systemic coordination across healthcare providers and healthcare delivery platforms, widespread practice of bribery and absence of formal grievance redress platforms affect effective leadership and governance. There appears to be a trust deficit among patients and healthcare providers. The private sector, with a majority of healthcare providers lacking adequate training, operates to maximize profit, and healthcare for the poor is at best seen as charity. CONCLUSIONS: Systemic impediments in local health systems hinder the delivery of quality diabetes care to the urban poor. There is an urgent need to address these weaknesses in order to improve care for diabetes

    Full Text Available PURPOSE: To study the epidemiological characteristics of bacterial keratitis seen at a tertiary eye care referral centre in south India. METHODS: A retrospective review of medical records of all culture-positive bacterial keratitis which were seen over a 3 years period, from September 1999 through August 2002 was performed. After clinical evaluation corneal scrapings were collected and subjected to culture and microscopy using standard protocols in all patients. RESULTS: Out of 3183 corneal ulcers evaluated, 1043(32.77% were found to be of bacterial aetiology. A total of 1109 bacterial pathogens were isolated from 1046 eyes with keratitis. The predominant bacterial species isolated was Streptococcus pneumoniae (37.5%. Males were 592(56.76% and 451(43.24% were females. There were 564(54.07% rural residents and 479(45.93% urban residents; this difference was statistically significant (p< 0.0001. Patients with age more than 50 years (60.2% were affected significantly more than patients aged less than 50 years (30.8%. While 57.62% of patients were non-agricultural workers, 42.38% were farmers; this difference was statistically significant (p<0.0001. Co-existing ocular diseases predisposing to corneal ulceration were identified in 703(67.4% patients, compared to other predisposing risk factors in 340(32.6% patients. One hundred and seventy seven (16.97% had corneal injury with soil and/or sand, compared to 115(11.03% patients who had injury due to other materials and the difference was statistically significant. There was lower incidence of bacterial keratitis from June to September. CONCLUSIONS: The epidemiological characteristics of bacterial keratitis vary geographically. This study describing the features of bacterial keratitis would greatly help the practising ophthalmologist and other medical practitioners in the management of their patients.

    Probabilistic seismic hazard analysis (PSHA) is carried out for the archaeological site of Vijayapura in south India in order to obtain hazard consistent seismic input ground-motions for seismic risk assessment and design of seismic protection measures for monuments, where warranted. For this purpose the standard Cornell-McGuire approach, based on seismogenic zones with uniformly distributed seismicity is employed. The main features of this study are the usage of an updated and unified seismic catalogue based on moment magnitude, new seismogenic source models and recent ground motion prediction equations (GMPEs) in logic tree framework. Seismic hazard at the site is evaluated for level and rock site condition with 10% and 2% probabilities of exceedance in 50 years, and the corresponding peak ground accelerations (PGAs) are 0.074 and 0.142 g, respectively. In addition, the uniform hazard spectra (UHS) of the site are compared to the Indian code-defined spectrum. Comparisons are also made with results from National Disaster Management Authority (NDMA 2010), in terms of PGA and pseudo spectral accelerations (PSAs) at T = 0.2, 0.5, 1.0 and 1.25 s for 475- and 2475-yr return periods. Results of the present study are in good agreement with the PGA calculated from isoseismal map of the Killari earthquake, {M}w = 6.4 (1993). Disaggregation of PSHA results for the PGA and spectral acceleration ({S}a) at 0.5 s, displays the controlling scenario earthquake for the study region as low to moderate magnitude with the source being at a short distance from the study site. Deterministic seismic hazard (DSHA) is also carried out by taking into account three scenario earthquakes. The UHS corresponding to 475-yr return period (RP) is used to define the target spectrum and accordingly, the spectrum-compatible natural accelerograms are selected from the suite of recorded accelerograms.

    There are limited data on the use of artificial intelligence methods for the diagnosis of dementia in epidemiological studies in low- and middle-income country (LMIC) settings. A culture and education fair battery of cognitive tests was developed and validated for population based studies in low- and middle-income countries including India by the 10/66 Dementia Research Group. We explored the machine learning methods based on the 10/66 battery of cognitive tests for the diagnosis of dementia based in a birth cohort study in South India. The data sets for 466 men and women for this study were obtained from the on-going Mysore Studies of Natal effect of Health and Ageing (MYNAH), in south India. The data sets included: demographics, performance on the 10/66 cognitive function tests, the 10/66 diagnosis of mental disorders and population based normative data for the 10/66 battery of cognitive function tests. Diagnosis of dementia from the rule based approach was compared against the 10/66 diagnosis of dementia. We have applied machine learning techniques to identify minimal number of the 10/66 cognitive function tests required for diagnosing dementia and derived an algorithm to improve the accuracy of dementia diagnosis. Of 466 subjects, 27 had 10/66 diagnosis of dementia, 19 of whom were correctly identified as having dementia by Jrip classification with 100% accuracy. This pilot exploratory study indicates that machine learning methods can help identify community dwelling older adults with 10/66 criterion diagnosis of dementia with good accuracy in a LMIC setting such as India. This should reduce the duration of the diagnostic assessment and make the process easier and quicker for clinicians, patients and will be useful for 'case' ascertainment in population based epidemiological studies.

    Almost half of all children in South Asia are stunted. Although agriculture has the potential to be a strong driver of undernutrition reduction and serves as the main source of livelihood for over half of South Asia's population, its potential to reduce undernutrition is currently not being realized. The Leveraging Agriculture for Nutrition in South Asia (LANSA) research consortium seeks to understand how agriculture and agrifood systems can be better designed to improve nutrition in South Asia. In 2013 and 2014, LANSA carried out interviews with stakeholders influential in, and/or knowledgeable of, agriculture-nutrition policy in India, Pakistan, and Bangladesh, to gain a better understanding of the institutional and political factors surrounding the nutrition sensitivity of agriculture in the region. Semistructured interviews were carried out in India, Bangladesh, and Pakistan with a total of 56 stakeholders representing international organizations, research, government, civil society, donors, and the private sector. The findings point to mixed perspectives on countries' policy sensitivity toward nutrition. There was consensus among stakeholders on the importance of political commitment to nutrition, improving nutrition literacy, strengthening capacities, and improving the use of financial resources. Although there are different ways in which South Asian agriculture can improve its impact on nutrition, sensitizing key influencers to the importance of nutrition for the health of a country's population appears as a critical issue. This should in turn serve as the premise for political commitment, intersectoral coordination to implement nutrition-relevant policies, adequately resourced nutrition-specific and nutrition-sensitive programs, and sufficient capacities at all levels. © The Author(s) 2015.

    The transfer factors of trace elements from soil to medicinal plants were determined in the region of Hassan district of south India. The trace element concentration was determined using the Energy Dispersive X-ray Fluorescence (ED-XRF) spectrometer. The transfer factors were found in the order Rb > Sr > Ca > K > Zn > Cu > Mn. The transfer factors were found to be high, for most of the plants. The concentration of Rb and Sr was found to be high in medicinal plants, which can be attributed to the mineralogy of the region and plant morphology.

The time to normalisation of whole blood clotting time, mortality and complications were not different between the groups. The average dose of ASV required in the low and high dose groups were 106 mL and 246 mL, respectively. Consequently, patients who received low dose ASV incurred approximately 50% less expense. Urticarial rashes were also significantly fewer in the low dose group.

    Antenatal depression is a highly prevalent disorder with serious implications on maternal and child outcomes. There are few studies examining this in low-middle-income community settings. To determine the prevalence of antenatal depression in women from a coastal rural background in Kerala and Tamil Nadu and to determine its associated factors. In this cross-sectional community-based study, in 202 antenatal women, standard interview and diagnostic criteria (Clinical Interview Schedule-Revised (CIS-R)) were employed for identifying depression and examining a wide range of putative clinical and sociocultural risk factors including domestic violence. There was a 16.3% prevalence of depression among the 202 women sampled. The possible risk factors after stepwise backward regression were pressure to have a male child, 11.48 (2.36-55.78); financial difficulties, 8.23 (2.49-27.22); non-arranged marriage, 6.05 (1.72-21.23); history of miscarriage-still birth, 5.77 (1.55-21.43) and marital conflict, 9.55 (2.34-38.98). There is a need to develop strategies for recognition and appropriate intervention for antenatal depression, in the context of locally relevant risk factors, so as to improve both maternal and child outcomes. © The Author(s) 2015.

    Fluoride contamination is one of the most alarming issues for those countries that depend on groundwater drinking water supply. A careful examination of the hydrogeochemical conditions and routine monitoring of fluoride level are therefore quintessential. Estimation of natural background level (NBL) of fluoride becomes significant information for assessing the current and future contamination episodes. Vellore District in Tamil Nadu is a hard rock terrain known for its F-rich groundwater. In this study, we attempted to form a benchmark for fluoride using hydrochemical pre-selection (based on TDS and NO 3 ) and cumulative probability plots (CPP). Principle components analysis is (PCA) applied to evaluate the corresponding factor grouping of the total of 68 samples, which is later mapped using geostatistical tool in ArcGIS. From the CPP, we derived the NBL of F as 0.75 mg/L. This value is compared with the observed concentration in each sample and they were spatially plotted based on the NBL. Resultant plot suggests that W-NW part of the study area has exceeded and E-EW regions are below the NBL of F. Spatial variation of the factor scores also supported this observation. Grounding an NBL and extending it to other parts of the potential contaminated aquifers are highly recommended for better understanding and management of the water supply systems.

    Background The heterogeneity of A and B alleles results in weak variants of these antigens. Subgroups of A differ from each other quantitatively and qualitatively. The expected frequencies of A1 and A2 subtypes will be in Hardy-Weinberg equilibrium for the Mendelian inheritance of the allelic A1 and A2 genes. The frequency of A subgroups in the population from south India is not known. The aim of our study was to study the frequency of A subtypes and the prevalence of anti-A1 antibody among this population. Methods Over a period of 3 years, patients’ blood group was typed using a standard tube technique. Anti-A1 lectin studies were done for all patients with groups A and AB. Based on serological reactivity the samples were classified into A1/A1B, A2/A2B and weak A subgroups. The prevalence of A subgroups was determined. The significance of differences in proportions was analysed using the chi-square test. Results A total of 40,113 patients’ samples were typed for ABO, Rh group and A subgroups in our blood bank attached to a tertiary care hospital. Among 10,325 group A samples, 98.14% classified as A1, 1.07% as A2, and 0.01% as weak A; the remaining group A samples were from neonates and reacted poorly with anti A1-lectin. The majority of AB samples (n=2,667) were of A1B type (89.28%). However, the proportion of A2B (8.99%) among AB samples was significantly higher than that of A2 in group A samples (p A1 antibodies among A2 and A2B samples was 1.8% and 3.75%, respectively, and none of them showed reactivity at 37°C. Conclusion The results of our study show a significantly higher proportion of A2B subtypes than A2 subgroups. A similar imbalance is seen in blacks and Japanese. The incidence of anti-A1 antibodies is also higher among A2B patients. PMID:20967168

    Sleep-related disorders (SRDs) though frequent, are under-reported and their implications are often neglected. To estimate SRDs in an apparently healthy South Indian population. Data was collected by administering a questionnaire including Sleep Disorders Proforma, Epworth Sleepiness Scale, and Pittsburgh Sleep Quality Index (PSQI) to 1050 apparently healthy attendants/relatives of patients attending a tertiary healthcare institution. The mean age of the respondents was 35.1±8.7 years with even gender distribution (male: female; 29:21), work hours were 7.8±1.33 h and had regional representation from the southern Indian states. The majority of the respondents did not report any significant medical/psychiatric co-morbidities, hypertension was noted in 42.6%, in one-fourth, the body mass index (BMI) was >25, and in 7.7% the neck size was >40 cm. Daily tea (70.3%) and coffee (17.9%) consumption was common and 22.2% used tobacco. Average time-to-fall-asleep was 22 min (range: 5-90 min), average duration-of-actual-sleep was 7 h (range: 3.5-9.1 h) with the majority (93.8%) reporting good-quality sleep (global PSQI ≤5). The reported rates of SRDs varied between 20.0% and 34.2% depending on the instrument used in the questionnaire. Insomnia, sleep-related breathing disorders (SRBD), narcolepsy, and restless legs syndrome (RLS) were reported by 18.6%, 18.4%, 1.04% and 2.9%, respectively. Obesity was not strongly associated with SRBD. in 51.8% of subjects with SRBD BMI was sleep, 18% in maintaining sleep and 7.9% had early morning awakening. Respondents attributed insomnia to depression (11.7%) or anxiety (2.5%). Insomnia was marginally high in females when compared to males (10.3% vs. 8.3%) and depression was the major reason. RLS, which was maximal at night, was responsible for delayed sleep onset (74.2%). Other SRDs included night terrors (0.6%), nightmares (1.5%), somnambulism (0.6%), and sleep-talking (2.6%). Family history of SRDs was present in 31.4% respondents

    2018-03-01

    Full Text Available Drawing from the scholarship on women’s history, social movements in the wake of ‘globalisation’, and critical debates in feminism, this paper locates the historically-embedded networks of feminist politics that persistently shape contemporary feminism(s in India/South Asia. This is an attempt to review the spatial dimensions of connections among the local, national, and global contexts, where gender becomes a foundational category for defining the relations of power. The critical debates on gender, space, and time have contributed to re-thinking the idea of region cutting across geo-political borders and bring the questions of memory within the study of territorial boundedness. How a territorial unit becomes an institutionalised entity of social, cultural, political practices and consciousness can provide an apt conceptual framework for unpacking structures of inequalities that feminist politics addresses. The historical memories have shaped not only the postcolonial nationalist discourses but also became critical for territorialised identities within and across national borders. With a focus on the manners in which discourses of gender violence travel and how unexpected connections among historical events construct different meanings for local and global and the local-global interface, this paper tries to situate the ‘politics of space/time’ in the region of India/South Asia.

The original Child-OIDP was obtained from the author, cross-culturally adapted to the Kannada language then the translation's content, face criterion and construct validity and internal and external reliability were evaluated. Children recorded their oral health problems and rated their oral health in a cross sectional study of 505, 11-12 year olds selected from a list of Karnataka schools by using simple random sampling (89.7% participation rate). The child OIDP revealed good validity and reliability. In relation to construct validity; an exploratory factor analysis provided two factors with eigenvalues greater than 1, which represented the physical and psychosocial health components. Cronbach's alpha was 0.60 and test-retest reliability, 0.85 (intra-class correlation coefficient). The Kannada Child-OIDP is a valid and reliable interviewer-administered instrument to measure the impact of the oral conditions on quality of life in children in Karnataka, South India.

    Shigella species are an important cause of acute diarrheal disease worldwide. This study describes the prevalence of Shigella spp. serotypes and their resistance profile in Vellore, South India from 2014 to 2015. From 2014 to 2015, 338 Shigella strains were isolated from stool samples at Christian Medical College, Vellore, India. Identification and serotyping was carried out using standard protocols. Antimicrobial susceptibility testing was done against commonly used antibiotics. Multidrug resistance was detected in 157 isolates. A subset of 73 isolates was randomly characterized further for acquired antimicrobial resistance genes in this study. The resistance profile of the study isolates varied by species and year. S. sonnei isolates were 100% resistant to all tested antibiotics in 2014, whereas in 2015, resistance was found for AMP-NAL-TAX-SXT-FIX. The resistance phenotypes among S. flexneri isolates for the year 2014 and 2015 were AMP-SXT-NAL-NOR-FIX-TAX and AMP-NAL-SXT-TAX-NOR-FIX respectively. Screening for antimicrobial resistance genes in S. flexneri found dhfr1A , sulII , bla OXA , bla TEM , bla CTX-M-1, qnr B, qnr S and AmpC genes while S. sonnei were found to have only dhfr1A , sulII, bla CTX-M-1 and qnr S genes respectively. Antimicrobial resistance genes were predominantly seen in AMP-SXT-NAL and AMP-SXT-NAL-NOR resistance phenotypes. Shigella prevalence of 4.8% to 4.6% was documented between the years 2014 to 2015 in this study. We show evidence that resistance to commonly used antibiotics continues to increase among Shigella spp. in South India. The presence of qnr S and bla CTX-M-15 in the study isolates further indicates the threat of spreading resistance to quinolones and third-generation cephalosporins.

    Most of the annual rainfall over India occurs during the Southwest (June-September) and Northeast (October-December) monsoon periods. In March 2008, however, Southern peninsular India and Sri Lanka received the largest rainfall anomaly on record since 1979, with amplitude comparable to summer-monsoon interannual anomalies. This anomalous rainfall appeared to be modulated at intraseasonal timescale by the Madden Julian Oscillation, and was synchronous with a decaying La Nina event in the Pacific Ocean. Was this a coincidence or indicative of a teleconnection pattern? In this paper, we explore factors controlling rainfall over southern India and Sri Lanka between January and April, i.e. outside of the southwest and northeast monsoons. This period accounts for 20% of annual precipitation over Sri Lanka and 10% over the southern Indian states of Kerala and Tamil Nadu. Interannual variability is strong (about 40% of the January-April climatology). Intraseasonal rainfall anomalies over southern India and Sri Lanka are significantly associated with equatorial eastward propagation, characteristic of the Madden Julian Oscillation. At the interannual timescale, we find a clear connection with El Nino-Southern Oscillation (ENSO); with El Ninos being associated with decreased rainfall (correlation of -0.46 significant at the 98% level). There is also a significant link with local SST anomalies over the Indian Ocean, and in particular with the inter-hemispheric sea surface temperature (SST) gradient over the Indian Ocean (with colder SST south of the equator being conducive to more rainfall, correlation of 0.55 significant at the 99% level). La Ninas/cold SSTs south of the equator tend to have a larger impact than El Ninos. We discuss two possible mechanisms that could explain these statistical relationships: (1) subsidence over southern India remotely forced by Pacific SST anomalies; (2) impact of ENSO-forced regional Indian Ocean SST anomalies on convection. However, the

    Full Text Available Holocene sequences in the humid tropical region of Kerala, South-western (SW India have preserved abundance of organic-rich sediments in the form of peat and its rapid development in a narrow time frame towards Middle Holocene has been found to be significant. The sub-coastal areas and flood plains of the Greater Pamba Basin have provided palaeorecords of peat indicating that the deposits are essentially formed within freshwater. The combination of factors like stabilized sea level and its subsequent fall since the Middle Holocene, topographic relief and climatic conditions led to rapid peat accumulation across the coastal lowlands. The high rainfall and massive floods coupled with a rising sea level must have inundated > 75% of the coastal plain land converting it into a veritable lagoon-lake system that eventually led to abrupt termination of the forest ecosystem and also converted the floodplains into peatland where accumulation of peat almost to 2.0-3.0 m thickness in coastal lowlands and river basins during the shorter interval in the Middle Holocene. Vast areas of the coastal plains of Kerala have been converted into carbon rich peatland during the Middle Holocene and transforming the entire coastal stretch and associated landforms as one of the relatively youngest peatlands in the extreme southern tip of India. Unlike the uninterrupted formation of peatlands of considerable extent during the Holocene in Southeast Asia, the south Peninsular Indian region has restricted and short intervals of peatlands in the floodplains and coastal lowlands. Such a scenario is attributed to the topographic relief of the terrain and the prevailing hydrological regimes and environmental conditions as a consequence of monsoon variability since Middle Holocene in SW India. Considering the tropical coastal lowlands and associated peatlands are excellent repositories of carbon, they are very important for regional carbon cycling and habitat diversity. The

    The genetic profile based on autosomal markers, four microsatellite DNA markers (D8S315, FES, D8S592, and D2S1328) and two minisatellite DNA markers (TPMT and PDGFA), were analyzed in six endogamous populations to examine the effect of geographic and linguistic affiliation on the genetic affinities among the groups. The six populations are from three different states of India and are linguistically different. Marathas from western India speak Marathi, an Indo-European language. Arayas, Muslims, Ezhavas, and Nairs from Kerala state of South India speak Malayalam, and Iyers from Tamil Nadu state speak Tamil. Genomic DNA was extracted from peripheral blood samples of random, normal, healthy individuals. Locus-specific PCR amplification was carried out, followed by electrophoresis of the amplicons and genotyping. All the loci were highly polymorphic and followed Hardy-Weinberg equilibrium, except for loci D8S315 and PDGFA in Iyers and Marathas, respectively. All six loci had high heterozygosity (average heterozygosity ranged from 0.73 to 0.76) and high polymorphism information content (0.57-0.90). The extent of gene differentiation among the six populations (G(ST) = 0.030) was greater than that for four Kerala populations (G(ST) = 0.011), suggesting proximity between the four Kerala populations. This result conforms with the cultural and linguistic background of the populations. The extent of diversity found among the populations probably resulted from the strict endogamous practices that they follow.

Based on the stress process model, we assessed the association of type and number of impairments of older persons (∼primary stressors) with caregiver burden among their family caregivers in rural South India. All impaired older persons (aged ≥60, with impairment in activities of daily living (ADL) or cognition or vision or hearing) residing in 8 villages in Bangalore district, Karnataka, India, and their primary informal caregivers were interviewed. Caregiver burden was measured using the Zarit Burden Interview (ZBI; higher score indicating greater perceived burden). Linear regression models, adjusting for background characteristics of older persons and caregivers, assessed the association of type of impairment (physical [Yes/No], cognitive [Yes/No], vision [Yes/No] and hearing [Yes/No]) and number (1 or 2 or 3 or 4) of older person impairments with caregiver burden. A total of 140 caregivers, caring for 149 older persons, were interviewed. The mean (standard deviation) ZBI score was 21.2 (12.9). Of the various older person impairments, ZBI score was associated only with physical impairment (β=6.6; 95% CI: 2.1-11.1). Relative to caregivers of older person with one impairment, those caring for an older person with all 4 impairments had significantly higher ZBI score (β=13.9; CI: 2.5-25.4). Caregivers of older persons with multiple impairments, especially physical impairment, are vulnerable. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Abstract Background India has 2.0 million estimated tuberculosis (TB cases per annum with an estimated 280,000 TB-related deaths per year. Understanding when in the course of TB treatment patients die is important for determining the type of intervention to be offered and crucially when this intervention should be given. The objectives of the current study were to determine in a large cohort of TB patients in India:- i treatment outcomes including the number who died while on treatment, ii the month of death and iii characteristics associated with "early" death, occurring in the initial 8 weeks of treatment. Methods This was a retrospective study in 16 selected Designated Microscopy Centres (DMCs in Hyderabad, Krishna and Adilabad districts of Andhra Pradesh, South India. A review was performed of treatment cards and medical records of all TB patients (adults and children registered and placed on standardized anti-tuberculosis treatment from January 2005 to September 2009. Results There were 8,240 TB patients (5183 males of whom 492 (6% were known to have died during treatment. Case-fatality was higher in those previously treated (12% and lower in those with extra-pulmonary TB (2%. There was an even distribution of deaths during anti-tuberculosis treatment, with 28% of all patients dying in the first 8 weeks of treatment. Increasing age and new as compared to recurrent TB disease were significantly associated with "early death". Conclusion In this large cohort of TB patients, deaths occurred with an even frequency throughout anti-TB treatment. Reasons may relate to i the treatment of the disease itself, raising concerns about drug adherence, quality of anti-tuberculosis drugs or the presence of undetected drug resistance and ii co-morbidities, such as HIV/AIDS and diabetes mellitus, which are known to influence mortality. More research in this area from prospective and retrospective studies is needed.

    Vishnudas, Subha; Savenije, Hubert H. G.; Zaag, Pieter Van der

    Attappady is a rural area in Kerala, South India, that has suffered from severe land degradation and which is inhabited by a poor and predominantly tribal population. The combination of severe land degradation, poverty and a tribal population make Attappady hydrologically and socially unique. Ecological degradation and deforestation followed the gradual building up of land pressure resulting from immigration by more wealthy outsiders. The hills of Attappady were once the forest land of Kerala. Recently it was on the verge of complete degradation. This paper explains how an ecorestoration project involving soil and water conservation interventions, the introduction of agro-forestry, nutritional diversification, income generation activities and training was implemented in a participatory manner. The project had positive impacts on both the environment and the livelihoods of the people living in the watershed, but it also suffered from drawbacks. This paper reports on the successes as well as the lessons learned from this unique ecorestoration project.

    Trace element concentration in the beach placer mining areas of Kanyakumari coast, South India was assessed. Sewage and contaminated sediments from mining sites has contaminated the surface sediments. Enrichment factor indicates moderately severe enrichment for Pb, minor enrichment for Mn, Zn, Ni, Fe and no enrichment for Cr and Cu. The Igeo values show higher concentration of Pb ranging in the scale of 3-4, which shows strong contamination due to high anthropogenic activity such as mining and terrestrial influences into the coastal regions. Correlation coefficient shows that most of the elements are associated with each other except Ni and Pb. Factor analysis reveals that Mn, Zn, Fe, Cr, Pb and Cu are having a significant loading and it indicates that these elements are mainly derived from similar origin. The cluster analysis clearly indicated that the mining areas are grouped under cluster 2 and non-mining areas are clustered under group 1. Copyright © 2017 Elsevier Ltd. All rights reserved.

    In the purview of global warming, the present study attempts to project changes in climate and quantify the changes in aridity of two coastal districts in south India under the RCP 4.5 trajectory. Projected climate change output generated by RegCM 4.4 model, pertaining to 14 grid points located within the study area, was analyzed and processed for this purpose. The meteorological parameters temperature and precipitations were used to create De Martonne Aridity Index, to assess the spatial distribution of aridity. The original index values ranged from 13.7 to 16.4 mm/°C, characterizing this area as a semidry climate. The outcome from the changed scenario analysis under RCP 4.5 showed that, during the end of the 21st century, the aridity may be increased more as the index values tend to reduce. The increasing trend in the drying phenomenon may be attributed to the rising of mean annual temperatures.

    An essential issue in future climate negotiations is how to bring developing countries on board. This paper proposes and applies the two-level interest-based model to analyze the factors that affect the likely stances of the 'Plus Five' countries (Brazil, China, India, Mexico, and South Africa) on international climate negotiations. This study finds mitigation capability to be a crucial factor which consists of at least such sub-factors as per capita income, energy endowment, and economic structure, while ecological vulnerability does not seem to play an important role which includes reductions in agricultural outputs, sea-level rise, climate-related natural disasters, and others. The paper proposes six options in an ascending order of stringency that the Plus Five are likely to adopt. The paper suggests that the 'Basic Four' (the Plus Five excluding Mexico), particularly China and India, are less likely to adopt a voluntary commitment to an emissions cap on the national economy in the near future than Mexico, which has the highest mitigation capability among all five. The Basic Four are likely to adopt more stringent climate polices with increasing mitigation capabilities, suggesting the importance of effective international financial and technology transfer mechanisms and further tighten emission reduction targets from developed countries.

    Violence against women is an emerging problem worldwide and more so in India. Considering its adverse effects on women's health, assessing the burden of violence in the community will help in planning services for the victims. To determine the prevalence of domestic violence and to identify factors associated with domestic violence among married women in reproductive age group in rural Puducherry. A community-based cross-sectional study was carried out in a rural area of Puducherry, South India. Married women in reproductive age group were interviewed using structured pretested questionnaire. Domestic violence was assessed using 12 questions that were used in National Family Health Survey-3. Adjusted odds ratios (AORs) were calculated using multivariate logistic regression to identify factors associated with violence. Of 310 study participants, 56.7% of them reported some form of domestic violence, 51.3% reported psychological violence, 40% reported physical violence, and 13.5% reported sexual violence. A statistically significant association was found between illiteracy of women and domestic violence (AOR: 4.3, 95% confidence interval: 1.1-15.7 P: 0.03). The other factors such as love marriage and nonregistration of marriage were significantly associated with violence. The prevalence of domestic violence was found to be high in this rural setting. Multisectoral response such as improving literacy, creating awareness regarding legal aid and screening the victims of violence at primary health centers, should be initiated to mitigate this public health issue.

    The article presents the results for enrichment of total trace metals (TTMs) from Pallikaranai salt marsh in South Chennai, a metropolis on the southeast coast of India. TTMs Fe, Mn, Cr, Cu, Ni, Co, Pb, Zn, Cd, Sr, V, and Hg along with sediment texture, OC, and CaCO3 were analyzed in 36 surface sediments collected during August 2008 to recognize and observe the input of TTMs in the marsh from various sources in the city limits. In view of the rapid urbanization and industrialization in Chennai City, especially on the southern side, uncontrolled input of sewage, garbage, and industrial effluents into the Pallikaranai marsh land, the elevated concentrations are not surprising. The level of enrichment of TTMs has also increased by 20% to 60% for most of the elements when compared with all other ecosystems in the world as well as the nearby area. The results also indicate that the marshy region is more heavily contaminated with Cd, Hg, Cr, Cu, Ni, Pb, and Zn than other regions on the southeast coast of India. The Enrichment Factor, Contamination Factor, and I (geo) indexes are calculated, and these values are useful to assess the degree of pollution in sediments. The spatial distributions of TTMs are also controlled by other factors like geochemical, precipitation, and flocculation of particulate substances in the marsh. The results of the present study suggest the need for a regular monitoring and management program which will help to improve the quality of Pallikaranai pristine marsh land.

    Full Text Available In resource-constrained settings and in the context of HIV-infected patients requiring intensive care, value-laden decisions by critical care specialists are often made in the absence of explicit policies and guidelines. These are often based on individual practitioners’ knowledge and experience, which may be subject to bias. We reviewed published information on legislation and practices related to intensive care unit (ICU admission in India, Brazil and South Africa, to assess access to critical care services in the context of HIV. Each of these countries has legal instruments in place to provide their citizens with health services, but they differ in their provision of ICU care for HIV-infected persons. In Brazil, some ICUs have no admission criteria, and this decision vests solely on the ‘availability, and the knowledge and the experience’ of the most experienced ICU specialist at the institution. India has few regulatory mechanisms to ensure ICU care for critically ill patients including HIV-infected persons. SA has made concerted efforts towards non-discriminatory criteria for ICU admissions and, despite the shortage of ICU beds, HIV-infected patients have relatively greater access to this level of care than in other developing countries in Africa, such as Botswana. Policymakers and clinicians should devise explicit policy frameworks to govern ICU admissions in the context of HIV status. S Afr J HIV Med 2013;14(1:15-16. DOI:10.7196/SAJHIVMED.887

    The Dravidian communities are considered to be the original inhabitants of India, now restricted to South India. The southern most state, Kerala, is socio-culturally stratified into Hindus, Muslims and Christians on the basis of religion. The origin of these religious communities in Kerala is considered to be unique in comparison with that in other parts of the country. These communities were later influenced by the hierarchical caste structure established by the Hindu Brahmins. In the present study, we compared six nontribal (Namboothiri, Nair, Ezhava, Pulaya, Malabar Muslim and Syrian Christian) communities belonging to the major religious groups in Kerala (Hindu, Muslim and Christian) based on the human leukocyte antigen (HLA)-A, -B and -C diversity. Our aim was to understand the genomic substructuring associated with the changing social scenario in various caste and religious groups and compare it with the Dravidian tribal and other world populations. The present study reveals that the HLA diversity of the Dravidian communities is very distinct from that in the other world populations. It is obvious that the nontribal communities of Kerala display a greater Dravidian influence, but traces of genetic admixture with the Mediterranean, western European, central Asian and East Asian populations can be observed. This characterizes the crypto-Dravidian features of the nontribal communities of Kerala. Demic diffusion of the local progressive communities with the migrant communities may have given rise to crypto-Dravidian features among the nontribal communities of Kerala.

    Medication errors are common but most often preventable events in any health care setup. Studies on medication errors involving chemotherapeutic drugs are limited. We studied three aspects of medication errors - prescription, transcription and administration errors in 500 cancer patients who received ambulatory cancer chemotherapy at a resource limited setting government hospital attached cancer centre in South India. The frequency of medication errors, their types and the possible reasons for their occurrence were analysed. Cross-sectional study using direct observation and chart review in anmbulatory day care unit of a Regional Cancer Centre in South India. Prescription charts of 500 patients during a three month time period were studied and errors analysed. Transcription errors were estimated from the nurses records for these 500 patients who were prescribed anticancer medications or premedication to be administered in the day care centre, direct observations were made during drug administration and administration errors analysed. Medical oncologists prescribing anticancer medications and nurses administering medications also participated. A total of 500 patient observations were made and 41.6% medication errors were detected. Among the total observed errors, 114 (54.8%) were prescription errors, 51(24.5%) were transcribing errors and 43 (20.7%) were administration errors. The majority of the prescription errors were due to missing information (45.5%) and administration errors were mainly due to errors in drug reconstitution (55.8%). There were no life threatening events during the observation period since most of the errors were either intercepted before reaching the patient or were trivial. A high rate of potentially harmful medication errors were intercepted at the ambulatory day care unit of our regional cancer centre. Suggestions have been made to reduce errors in the future by adoption of computerised prescriptions and periodic sensitisation of the

    Full Text Available Context: There is a shortage of voluntary blood donors in developing countries which are, therefore, more dependent on replacement donors. Aim: To study the knowledge, attitude, and practices regarding voluntary blood donation in a rural block in Vellore, South India. Settings and Designs: A cross-sectional survey in randomly selected villages of a rural block in Vellore, South India. Materials and Methods: Knowledge, attitude, and practices were assessed using a pilot-tested, semi-structured, interviewer-administered questionnaire on randomly chosen rural adults aged between 18 and 60 years. Results: Of the 104 individuals interviewed, 90% were aware of voluntary blood donation, the main source of this awareness being television. Nearly, two-thirds of the participants felt they would fall sick by donating blood and that women and manual laborers were not capable of blood donation. Among the interviewed, 70.3% were of the opinion that blood can purchased with money. Only 44% were willing to donate blood on a voluntary basis. Perceived weakness and a misconception on the apparent lack of blood were the major reasons for unwillingness to donate blood. There was a significant association between willingness to donate blood and educational status as well as occupation, with the less educated and manual laborers unwilling to donate blood on a voluntary basis (odds ratio [OR] = 3.758, confidence interval [CI] = 1.54–9.156; OR = 5.333, CI = 1.429–19.90, respectively. Conclusions: The study found that although awareness on voluntary blood donation among individuals in the rural community was widespread, hesitancy to donate blood in real life situation was high. Since voluntary unpaid donors are the best candidates for blood donation, community being the best available source, education, and motivation of the community should play a greater role in increasing voluntary blood donation.

    Full Text Available Aim: A demographic study was conducted to understand the social status of the urban and rural patients attending a palliative care unit in South India. Methods: Fifty rural and 50 urban patients attending the palliative care outpatient clinic of the Christian Medical College and Hospital, South India were prospectively surveyed using a structured interview and home visits. Parameters studied included age, gender, marital status, education, occupation, religion, caste, housing, economic status, diagnosis, distance to the nearest health resource personnel and hospitals. Results: Occupation, religion, caste, housing, electricity, toilet and accessibility to health care were found to be significantly different between urban and rural patients. Seventy percent of the patients were below 60 years of age. The majority were unskilled laborers or housewives. One-third had never been to school and only 3% had been educated beyond high school. Half the patients slept on the floor, 50% of the dwellings had only one or two rooms and did not have toilets or running water. Ninety-five percent had electricity. The economic status of the patients correlated significantly with age, occupation and facilities in the house such as number of rooms, availability of beds, toilets and water supply. Women and older patients were significantly less likely to have completed school education. Women were less likely to be the main decision-makers and more likely to be the main caregivers. Conclusion: Economic status was a strong predictor of the various facilities available to the patient. A significant proportion of this population lived in deprived circumstances. A knowledge and understanding of the social conditions of the palliative care patients helps provide better-tailored care.

    Full Text Available Background: The promotional activities by medical representatives (MRs of the pharmaceutical companies can impact the prescribing pattern of doctors. Hence, the interaction between doctors and the pharmaceutical industry is coming under increasing scrutiny. Objective: The primary objective was to assess the attitude of the doctors toward the interaction with the MRs of the pharmaceutical company. The secondary objective was to assess the awareness of the doctors about regulations governing their interaction with the pharmaceutical company. Materials and Methods: This was a cross-sectional study. This study was carried out using a pretested questionnaire containing 10 questions between June and September 2014. The doctors working in the Dhanalakshmi Srinivasan Medical College and Hospital, Perambalur (Tamil Nadu during the study period was included. Results: A total of 100 pretested questionnaires were distributed, and 81 doctors responded (response rate 81%. 37% doctors responded that they interacted with MR once a week whereas 25.9% told that they interact with MRs twice a month. About 69.1% doctors think that MR exaggerate the benefits of medicines and downplays the risks and contraindications of medicine(P = 0.000. 61.7% doctors think that MR has an impact on their prescribing (P = 0.000. 63% doctors stated that they had received promotional tools such as stationery items, drug sample, textbooks or journal reprints from MR in last 12 months (P = 0.0012. Unfortunately, 70.4% doctors have not read the guidelines about interacting with the pharmaceutical industry or its representative (P = 0.000. Conclusion: Rather than forbidding any connection between doctors and industry, it is better to establish ethical guidelines. The Medical Council of India code is a step in the right direction, but the majority of doctors in this study have not read the guidelines about interacting with the pharmaceutical industry or its representative.

    A total of 31 Vibrio cholerae O1 (4- Inaba and 27- Ogawa serotype) isolates collected during a three-year period (2006-2009) from acute diarrheal cases in Tamil Nadu, India were analyzed for antibiotic resistance profiling, virulence-associated factors, genetic profiling by enterobacterial repetitive intergenic consensus sequence polymerase chain reaction (ERIC PCR), and biofilm-forming ability. Antibiotic resistance profile revealed that most of the strains have become multidrug-resistant strains. All the isolates are resistant to ampicillin and polymyxin B, 97% of the isolates are resistant to nalidixic acid, 90% to co-trimoxazole, 32.3% to norfloxacin and ciprofloxacin, 29% to doxycycline, 10% to gentamicin, whereas only 3% to chloramphenicol. Molecular characterization of virulence-associated genes by multiplex PCR revealed the presence of ace, ctxA, tcpA, toxR, and ompU as 93.5%, followed by ompW with 33.3%. The presence of zot was restricted to only one isolate and hlyA was not encountered in any of the strains. ERIC PCR produced more than 10 bands for each isolate and the dendrogram generated based on the cluster analysis showed the presence of 29 electrophoretic types among the 31 isolates. Isolates from different area or year of isolation are intermingled in all the clusters. With respect to biofilm formation, 24 isolates were found to be biofilm formers and eight of them produced strong biofilm. This study demonstrates the presence of critical virulence factors and antibiotic resistance in the diarrhea isolates, which signifies the importance of routine monitoring and proper treatment to prevent cholera outbreaks.

    Full Text Available Background: Indoor air pollution is still considered as one of the leading causes of morbidity and mortality worldwide and especially in developing countries, including India. This study aims to assess social, housing, and indoor environmental factors associated with respiratory health among mothers and children. Methods: The study was conducted in the city of Tirupur, South India. We quantitatively assessed the indoor exposure to fine particulate matter (PM2.5 and carbon monoxide in relation to respiratory health among women and children. Information on health status, household characteristics and socioeconomic factors was collected using a modified standardised questionnaire. Results: This study demonstrates the significant health impact of housing and socioeconomic characteristics on the burden of respiratory illness among women and children in urban South India. Increased respiratory symptoms were recorded among women and children from low income households, and those who allowed smoking inside. The mean PM2.5 concentration measured in this study was 3.8 mg/m3 which exceeded the World Health Organization (WHO 24 h guideline value of 0.025 mg/m3. Conclusions: This study is the first to our knowledge carried out in urban South India and the findings can be used for future intervention studies.

This study was undertaken to ascertain both employee and employer perceptions on barriers existing among Information Technology (IT) and IT-enabled sectors to employ persons with disabilities. Two hundred participants from six IT/IT-enabled sector organizations were included in the study; study was conducted at Hyderabad, India. A semi-structured questionnaire was administered to the participants. Physical access to and within the worksite was highlighted as a concern by 95% of respondents. Majority perceived that communication, attitude of people, discrimination, harassment at work place, and information were critical barriers. Only 3.8% of employers were aware that their company had a written policy on employing persons with disabilities. Employers stated that commitment and perseverance were important facilitators among persons with disabilities. Evidence from this study will help in planning need-based employment for persons with disabilities.

    Injuries now rank among the leading causes of morbidity and mortality the world over. Injuries are steadily increasing in developing countries like India. Systematic and scientific efforts in injury prevention and control are yet to begin in India. Data on injuries are very essential to plan preventive and control measures. The objective of this study is to know the profile of the injury cases admitted to M S Ramaiah hospital, Bangalore, India, using a cross-sectional study design for six months, i.e. from Oct 2008 to April 2009. The mean age of the study population was 35.3 years (SD = 15.38), 69.1% were injured in road traffic accidents (RTA), 28.7% due to falls and 2.2% due to burns. Nearly 14.4% were under the influence of alcohol. Nearly 73.6% of RTA cases were two-wheeler users, 48.5% had not followed sign boards and 56.5% had not obeyed the one-way rules, 63.5% of the two-wheeler users did not use helmets. Also, 38% of two wheelers had two pillion riders, whereas 57% of four-wheeler users had not used a seat belt. Among falls, 58% occurred at home, 49% occurred due to slippery surface. Road traffic accidents were the most common cause for injuries, in which two wheelers were most commonly involved. Strict enforcement of traffic rules and education on road safety are very essential to prevent injuries.

    This paper analyses how the 1950-61 conflict between Portugal and India over the territories that constituted Portuguese India (Goa, Daman and Diu) informed Portugal's relations with the World Health Organization's Regional Office for South East Asia (SEARO). The 'Goa question' determined the way international health policies were actually put into place locally and the meaning with which they were invested. This case study thus reveals the political production of SEARO as a dynamic space for disputes and negotiations between nation-states in decolonising Asia. In this context, health often came second in the face of contrasting nationalistic projects, both colonial and post-colonial.

    Full Text Available The Random Amplified Polymorphic DNA (RAPD technique was used to study the genetic diversity of four Elops machnata populations in South India. Elops machnata is considered as a least concern species (LC, categorized by the International Union for Conservation and Nature (IUCN. The population trends are currently stable in Indian Ocean, Eastern Africa, but are unknown throughout the rest of its expansive range, especially in Indian estuaries. Among the ten RAPD primers tested, eight primers got amplified and gave scorable bands. In total, 119 scorable bands were observed in all populations. The overall observed and effective number of alleles was found to be 2.000 ± 0.000 and 1.5307 ± 0.2503 respectively for the entire population. The overall polymorphic loci were 61.00% and the overall gene flow among the four populations was predicted to 0.1032. The genetic distance and geographic distance between the four populations showed a positive correlation. The highest genetic similarity (0.6824 was found between Parangipettai and Muthupettai population, which reflected the geographical relationship between them. Tow main clusters were obtained based on UPGMA dendrogram. This study proves that RAPD analysis has the ability to discriminate E. machnata populations in South Indian coastal waters.

    Full Text Available Recurrent heat waves, already a concern in rapidly growing and urbanizing South Asia, will very likely worsen in a warming world. Coordinated adaptation efforts can reduce heat’s adverse health impacts, however. To address this concern in Ahmedabad (Gujarat, India, a coalition has been formed to develop an evidence-based heat preparedness plan and early warning system. This paper describes the group and initial steps in the plan’s development and implementation. Evidence accumulation included extensive literature review, analysis of local temperature and mortality data, surveys with heat-vulnerable populations, focus groups with health care professionals, and expert consultation. The findings and recommendations were encapsulated in policy briefs for key government agencies, health care professionals, outdoor workers, and slum communities, and synthesized in the heat preparedness plan. A 7-day probabilistic weather forecast was also developed and is used to trigger the plan in advance of dangerous heat waves. The pilot plan was implemented in 2013, and public outreach was done through training workshops, hoardings/billboards, pamphlets, and print advertisements. Evaluation activities and continuous improvement efforts are ongoing, along with plans to explore the program’s scalability to other Indian cities, as Ahmedabad is the first South Asian city to address heat-health threats comprehensively.

    2014-12-01

    Interdependency between water and energy is generally transacted in trade-off mode; where either of the resource gets affected because of the other. Generally this trade-off is commonly known as water-energy nexus. Many studies have been undertaken in various parts of the world using various approaches to tease out the intricate nexus. This research has adopted a different approach to quantify the inter-dependency. The adopted approach made an attempt to tease out the nexus from demand side for both the resources. For water demand assessment PODIUM Sim model was used and for other parameters available secondary data was used. Using this approach percentage share of water for energy and energy for water was estimated. For an informed decision making and sustainable development, assessment was carried out at state level as most of the policies are made specifically for the state. The research was done for the southernmost state of India, Tamil Nadu which is a rapidly growing industrial hub. Tamil Nadu is energy and water intensive state and the analysis shows that the share of water demand from energy sector compared to water demand from other major sectors is miniscule. While, the energy demand in water sector for various processes in different sectors compared to energy demand as total has a comparable share of range 15-25%. This analysis indicated the relative risk sectors face in competition for the resource. It point outs that water sector faces fierce competition with other sectors for energy. Moreover, the results of the study has assessed that state has negative water balance, which may make access to water more energy intensive with time. But, a projection into future scenario with an assumption based on the ongoing policy program of improving irrigation efficiency was made. It provided a solution of a potential positive equilibrium which conserves both water and energy. This scenario gave promising results which indicated less of water demand from

    This article examined the prevalence of physical and sexual violence among 1,974 married women from 40 low-income communities in Chennai, India. The authors found a 99% and 75% lifetime prevalence of physical abuse and forced sex, respectively, whereas 65% of women experienced more than five episodes of physical abuse in the 3 months preceding the survey. Factors associated with violence after multivariate adjustment included elementary/middle school education and variables suggesting economic insecurity. These domestic violence rates exceed those in prior Indian reports, suggesting women in slums may be at increased risk for HIV and other sexually transmitted infections.

    Full Text Available The economic value of tank irrigation water was determined through Contingency Valuation Method by analyzing farmers’ willingness to pay for irrigation water under improved water supply conditions during wet and dry seasons of paddy cultivation. Quadratic production function was also used to determine the value of irrigation water. The comparison of the economic value of water estimated using different methods strongly suggests that the present water use pattern will not lead to sustainable use of the resource in the tank command areas. Policy options for sustainable use of irrigation water and management of tanks in India were suggested.

    Full Text Available The aetiology of fungal sinusitis is diverse and changing. Aspergillus species has been the most common cause for fungal sinusitis, especially in dry and hot regions like India. Trichosporon species as a cause for fungal sinusitis has been very rarely reported the world over. Here, we report a rare case of allergic fungal sinusitis caused by Trichosporon inkin in a 28-year-old immunocompetent woman. Bilateral nasal obstruction, nasal discharge and loss of smell were her presenting complaints. Diagnostic nasal endoscopy showed bilateral multiple polyps. Functional endoscopic sinus surgery was performed and many polyps were removed. Based on mycological and histopathological studies, the pathogen was identified as T. inkin.

    In recent times, several new species of amphibians have been described from India. Many of these discoveries are from biodiversity hotspots or from within protected areas. We undertook amphibian surveys in human dominated landscapes outside of protected areas in south western region of India between years 2013–2015. We encountered a new species of Microhyla which is described here as Microhyla laterite sp. nov. It was delimited using molecular, morphometric and bioacoustics comparisons. Microhyla laterite sp. nov. appears to be restricted to areas of the West coast of India dominated by laterite rock formations. The laterite rock formations date as far back as the Cretaceous-Tertiary boundary and are considered to be wastelands in-spite of their intriguing geological history. We identify knowledge gaps in our understanding of the genus Microhyla from the Indian subcontinent and suggest ways to bridge them. PMID:26960208

    In most parts of India, and particularly in South India, groundwater levels are hazardously declining, while agricultural groundwater use is increasing. The current issue is to address the probable evolution of water table levels in relation with climate and agricultural changes. The aim of the SHIVA-ANR project (http://www.shiva-anr.org) is to provide some indicators of the water availability at the village scale to evaluate the vulnerability of farmers facing global changes. This study focuses on a particularly water stressed semi-arid area of South India characterized by hard rock geology with naturally low recharge capacity and limited surface water availability. The study catchment is located in the agricultural area of the Kudaliar river watershed (980km^2) located 50 km north of Hyderabad, India. It is composed of about 120 villages. Socio economic surveys have been carried out at the village scale to evaluate the present socio-economic situation of farmers. It also provides more details on various cultural and irrigation practices at this scale. The landuse has been evaluated by remote sensing with two satellite images, one after monsoon (October 2009), and the other during dry season (March 2010). Groundwater-irrigated rice paddies represent about 10% of the area, whereas rainfed crop (corn and cotton) represent about 45%. Numerous small tanks (reservoir) situated on the river network define a water harvesting system of 2% of the catchment area which captures surface runoff during monsoon. No discharges data are available at the outlet, as the river is dry most of the year. A hydro-geological survey has been carried out to provide a map of aquifer thickness and the general state of the groundwater level before and after monsoon. The Soil Water Assessment Tool model (SWAT) has been calibrated to assess the water budget of the agricultural catchment under present conditions. Soil parameters calibration is made first on seasonal groundwater recharge for

    Full Text Available BACKGROUND The burning of firecrackers during Diwali festival produces an adverse respiratory outcome. However, there are no published articles on the impact of fireworks on hospital admission due to acute respiratory issues, hospital stay, and respiratory mortality during Diwali in India. MATERIALS AND METHODS This was a prospective, open label, observational study. It was conducted in patients admitted to the pulmonary emergency unit with respiratory symptoms 15 days before and after Diwali. It was conducted after the approval of ethics committee and written informed consent. RESULTS The number of admissions post-Diwali were significantly more compared to pre-Diwali from both rural and urban locations (p<0.001. The mean duration of hospital stay was significantly less pre-Diwali (7.59±0.74 days compared to post-Diwali (9.46±0.44 days. Also, significantly increased number of patients required ventilator support post Diwali. CONCLUSION The findings from the present study validate the deterioration of respiratory health during Diwali festival in India. There should be more awareness campaigns about the harmful effects of fire-crackers. Patients suffering from respiratory problems should be advised to avoid heavy exposure to fireworks

    Introduction: Amebiasis is the third leading cause of death after malaria and schistosomiasis. Diagnosis is based on microscopy, culture, isoenzyme analysis, and serology-based techniques. In resource-limited nation such as India where polymerase chain reaction cannot be employed, serology is considered to be the reliable diagnostic tool. To find the seroprevalence of Entamoeba histolytica IgG antibody by enzyme-linked immunosorbent assay (ELISA) among the liver abscess cases and healthy controls. Materials and Methods: Commercially available RIDASCREEN Entamoeba IgG ELISA kit was used to evaluate the samples as per manufacturer's instruction. Results: A total of 322 samples were evaluated by ELISA. 94/157 (59.87%) were positive for amebic liver abscess cases, 2/13 (15.38%) were positive in suspected amebiasis group, 5/15 (33.3%) were positive in nonamoebic hepatic disorder group, 5/39 (12.8%) were positive in other parasitic disorders, and 2/98 (2.04%) were positive in presumed healthy controls. The sensitivity and specificity of the assay were found to be 56% and 92%, respectively. Conclusion: In an endemic nation such as India and other developing countries, ELISA can be used as a routine surveillance test in a clinical setup to detect amoebiasis if the cases are judicially evaluated along with the other routine tests.

    Among the manifold uses of mobile phones, mobile-health (mHealth) has been an important one, which is the practice of public health initiatives by awareness raising and communication campaigns. Optimum utilization of mHealth is possible only through adequate awareness. Hence, we aimed to study the perceptions and knowledge about mHealth among college going students in Mangalore, India. A cross-sectional study was conducted in March 2014 among 627 students in selected engineering (302 students) and medical colleges (325 students) in Mangalore, India. Colleges were selected using convenience sampling (nonrandom) method. Data were collected using semi-structured self-administered questionnaire and analyzed. Overall, 48.9% were males, 61.4% belonged to 18-20 years age group. The awareness about mobile phone health utilities among medical and engineering students was found to be similar. Among those who were aware of the concept of mHealth (74 [11.2%]), 40 (54.1%) were medical students. Marginally higher proportion of medical students felt mHealth could be helpful in protecting the patients' confidentiality and would help in better communication with the patients. There was high level of general awareness about mHealth among the subjects. However, many specific areas had limited knowledge among both the streams of students, hence highlighting the need for increasing awareness and sensitization.

    There is a huge need for the availability of transplantable donor corneas worldwide to reduce the burden of corneal blindness due to corneal opacity. Voluntary eye donation depends on the awareness levels of various stakeholders in the community. This study aimed to assess the awareness level regarding eye donation among various stakeholders in Srikakulam district in the state of Andhra Pradesh, India. 355 subjects were selected from the district using multi stage random sampling. A pre tested semi structured questionnaire was used to collect information regarding each individual's awareness, knowledge, and perception regarding eye donation. Each response was scored individually and a total score was calculated. Univariate and multivariate regression analysis was used to determine the factors associated with willingness towards eye donation and increased awareness levels. Of the 355 subjects interviewed, 192 (54%) were male and 163 (46%) were female. The mean age of the stakeholders was 35.9 years (SD ±16.1) and all the study subjects were literate.

    Full Text Available Background: Violence against women is an emerging problem worldwide and more so in India. Considering its adverse effects on women′s health, assessing the burden of violence in the community will help in planning services for the victims. Objectives: To determine the prevalence of domestic violence and to identify factors associated with domestic violence among married women in reproductive age group in rural Puducherry. Materials and Methods: A community-based cross-sectional study was carried out in a rural area of Puducherry, South India. Married women in reproductive age group were interviewed using structured pretested questionnaire. Domestic violence was assessed using 12 questions that were used in National Family Health Survey-3. Adjusted odds ratios (AORs were calculated using multivariate logistic regression to identify factors associated with violence. Results: Of 310 study participants, 56.7% of them reported some form of domestic violence, 51.3% reported psychological violence, 40% reported physical violence, and 13.5% reported sexual violence. A statistically significant association was found between illiteracy of women and domestic violence (AOR: 4.3, 95% confidence interval: 1.1-15.7  P: 0.03. The other factors such as love marriage and nonregistration of marriage were significantly associated with violence. Conclusion: The prevalence of domestic violence was found to be high in this rural setting. Multisectoral response such as improving literacy, creating awareness regarding legal aid and screening the victims of violence at primary health centers, should be initiated to mitigate this public health issue.

    Brazil, Russia, India, China, and South Africa (BRICS) represent almost half the world's population, and all five national governments recently committed to work nationally, regionally, and globally to ensure that universal health coverage (UHC) is achieved. This analysis reviews national efforts to achieve UHC. With a broad range of health indicators, life expectancy (ranging from 53 years to 73 years), and mortality rate in children younger than 5 years (ranging from 10·3 to 44·6 deaths per 1000 livebirths), a review of progress in each of the BRICS countries shows that each has some way to go before achieving UHC. The BRICS countries show substantial, and often similar, challenges in moving towards UHC. On the basis of a review of each country, the most pressing problems are: raising insufficient public spending; stewarding mixed private and public health systems; ensuring equity; meeting the demands for more human resources; managing changing demographics and disease burdens; and addressing the social determinants of health. Increases in public funding can be used to show how BRICS health ministries could accelerate progress to achieve UHC. Although all the BRICS countries have devoted increased resources to health, the biggest increase has been in China, which was probably facilitated by China's rapid economic growth. However, the BRICS country with the second highest economic growth, India, has had the least improvement in public funding for health. Future research to understand such different levels of prioritisation of the health sector in these countries could be useful. Similarly, the role of strategic purchasing in working with powerful private sectors, the effect of federal structures, and the implications of investment in primary health care as a foundation for UHC could be explored. These issues could serve as the basis on which BRICS countries focus their efforts to share ideas and strategies. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The composite fore-arc/syncollisional Xigaze basin in south Tibet preserves a key record of India-Asia collision. New apatite fission track and zircon (U-Th)/He data from an N-S transect across the preserved fore-arc basin sequence near Xigaze show a consistent northward Late Cretaceous to middle Miocene younging trend, while coexisting apatite (U-Th-Sm)/He ages are all Miocene. Corresponding detrital zircon U-Pb data are also reported for constraining the Cretaceous depositional ages of the Xigaze basin sequence in the region. Thermal history modeling indicates that the basin experienced northward propagating episodic exhumation, along with a northward migration of the depocenter and a pre-existing Cenozoic syncollisional basin sequence which had been removed. In the southern part, fore-arc exhumation commenced in the Late Cretaceous ( 89 ± 2 Ma). Following transition to a syncollisional basin in the Paleocene, sedimentation in the central and northern Xigaze basin continued until the latest Eocene ( 34 ± 4 Ma). Ongoing folding and thrusting (e.g., Great Counter Thrusts) caused by progressive plate convergence during late Oligocene-early Miocene time resulted in regional uplift and considerable basin denudation, which fed two fluvial basins along its northern and southern flanks and exposed the basement ophiolite. Subsequent incision of the Yarlung River resulted in Miocene cooling in the region. Different episodes in the exhumation history of the Xigaze basin, caused by thrusting of an accretionary wedge and ophiolitic basement, can be linked to changes in India-Asia convergence rates and the changing subduction pattern of the Indian and Neo-Tethyan slabs.

    Kerala Registry of Epilepsy and Pregnancy had been prospectively evaluating the reproductive issues of women with epilepsy since April 1998. This analysis aimed to estimate the relative risk of major congenital malformations (MCM) to the registrants. All pregnancies with known outcome in this register until December 2013 were included. Malformation status was evaluated by antenatal ultrasonography, physical examination at birth, echocardiography, and abdomen ultrasonography at 3 months of age and a final review at 1 year of age. There were 1,688 fetuses (singlets 1,643, twins 21, and triplet 1) resulting in 1,622 live births. All were born to women of Asian origin living in South India. The MCM rate for all live births was 6.84% (95% confidence interval [CI] 5.71-8.18) and for all pregnancy outcomes including fetal loss was 7.11% (95% CI 5.98-8.44). The MCM rates (mean with 95% CI) for exposed group were 6.4% (5.03-8.03) for monotherapy and 9.9% (7.37-13.13) for polytherapy; internal control group (women with epilepsy [WWE] not on antiepileptic drugs [AEDs] in first trimester) 5.6% (3.34-9.11), external control group (women without epilepsy or AED exposure in first trimester) 3.45% (1.94-6.07). Valproate monotherapy group had a dose-dependent relative risk for MCM of 2.6 (95% CI 1.30-5.20) compared to the external control group. The preliminary data on MCM rate for the nine total clobazam monotherapy (22.2%; 95% CI 6.2-54.7) signals increased risk that needs further validation on larger sample size. There was no association between MCM rate and maternal socioeconomic status, epilepsy syndrome, or use of folic acid in first trimester. This dataset from South India confirms the increased risk of MCM with exposure to AEDs, particularly polytherapy. A dose-dependent increased risk was observed with valproate. The increased risk associated with clobazam monotherapy is an important signal that needs to be confirmed in a larger sample. Wiley Periodicals, Inc. © 2017

    Full Text Available Background: Acute undifferentiated febrile illness (AUFI may have similar clinical presentation, and the etiology is varied and region specific. Materials and Methods: This prospective observational study was conducted in a tertiary hospital in South India. All adult patients presenting with AUFI of 3-14 days duration were evaluated for etiology, and the differences in presentation and outcome were analyzed. Results: The study cohort included 1258 patients. A microbiological cause was identified in 82.5% of our patients. Scrub typhus was the most common cause of AUFI (35.9% followed by dengue (30.6%, malaria (10.4%, enteric fever (3.7%, and leptospirosis (0.6%. Both scrub typhus and dengue fever peaked during the monsoon season and the cooler months, whereas no seasonality was observed with enteric fever and malaria. The mean time to presentation was longer in enteric fever (9.9 [4.7] days and scrub typhus (8.2 [3.2] days. Bleeding manifestations were seen in 7.7% of patients, mostly associated with dengue (14%, scrub typhus (4.2%, and malaria (4.6%. The requirement of supplemental oxygen, invasive ventilation, and inotropes was higher in scrub typhus, leptospirosis, and malaria. The overall mortality rate was 3.3% and was highest with scrub typhus (4.6% followed by dengue fever (2.3%. Significant clinical predictors of scrub typhus were breathlessness (odds ratio [OR]: 4.96; 95% confidence interval [CI]: 3.38-7.3, total whole blood cell count >10,000 cells/mm 3 (OR: 2.31; 95% CI: 1.64-3.24, serum albumin <3.5 g % (OR: 2.32; 95% CI: 1.68-3.2. Overt bleeding manifestations (OR: 2.98; 95% CI: 1.84-4.84, and a platelet count of <150,000 cells/mm 3 (OR: 2.09; 95% CI: 1.47-2.98 were independent predictors of dengue fever. Conclusion: The similarity in clinical presentation and diversity of etiological agents demonstrates the complexity of diagnosis and treatment of AUFI in South India. The etiological profile will be of use in the development of

    Full Text Available Objective: To assess the nutritional status of adolescents of Indian origin living in India and the United Arab Emirates to see how variable the prevalence is of stunting and wasting among adolescents of the same ethnic background living in different socio-economic and demographic environments. Materials and Methods : A cross-sectional survey. Setting: Schools in South India and the United Arab Emirates. Participants: A total of 2459 adolescent boys and girls between the ages of 10 and 16 years old. Results and Discussion: Anthropometric measurements from 2459 adolescents between the ages of 10-16 years old, 1200 from India and 1259 from UAE, were collected. The subjects were divided into six age groups with 1-year intervals. Adolescents falling below the age and gender-specific 5 th percentile and 3 rd percentile of the WHO recommended standards were defined as having thinness and stunting accordingly. Regardless of gender, the rate of stunting was higher in Indian adolescents from India (25.5-51% when compared with Indian adolescents in UAE (3.1-21%. Thinness was also more in those in India (42-75.4%. When compared with adolescents living in the UAE (4.5-14.4%. The study was done in two groups having a common ethnicity but living in different socio-economic environments. With the results of this study, we can say that improved economic conditions favor better expression of genetic potential for physical growth.

    Full Text Available Context: Hand, foot, and mouth disease (HFMD remains a common problem in India, yet its etiology is largely unknown as diagnosis is based on clinical characteristics. There are very few laboratory-based molecular studies on HFMD outbreaks. Aim: The aim of this study was to characterize HFMD-related isolates by molecular techniques. Settings and Design: Between 2005 and 2008, during two documented HFMD outbreaks, 30 suspected HFMD cases presented at the Outpatient Unit of the Department of Dermatology, Christian Medical College (CMC, Vellore. Seventy-eight clinical specimens (swabs from throat, mouth, rectum, anus, buttocks, tongue, forearm, sole, and foot were received from these patients at the Department of Clinical Virology, CMC, for routine diagnosis of hand, foot, and mouth disease. Materials and Methods: Samples from these patients were cultured in Vero and rhabdomyosarcoma (RD cell lines. Isolates producing enterovirus-like cytopathogenic effect (CPE in cell culture were identified by a nested reverse transcription-based polymerase chain reaction (RT-PCR and sequenced. The nucleotide sequences were analyzed using the BioEdit sequence program. Homology searches were performed using the Basic Local Alignment Search Tool (BLAST algorithm. Statistical Analysis used: The statistical analysis was performed using Epi Info version 6.04b and Microsoft Excel 2002 (Microsoft Office XP. Results: Of the 30 suspected HFMD cases, only 17 (57% were laboratory confirmed and Coxsackievirus A16 (CVA16 was identified as the etiological agent in all these cases. Conclusions: Coxsackievirus A16 (CVA16 was identified as the virus that caused the HFMD outbreaks in Vellore between 2005 and 2008. Early confirmation of HFMD helps to initiate control measures to interrupt virus transmission. In the laboratory, classical diagnostic methods, culture and serological tests are being replaced by molecular techniques. Routine surveillance systems will help understand the

    Malaria is a serious disease which has repeatedly threatened Andaman, an island territory of India. Uncharted dense vegetation and inaccessibility are the salient features of the area and the major areas are covered by remotely sensed data to identify the malaria vector's natural habitat. The present investigation appraises the role of geospatial technologies in identifying the natural habitat of malarial vectors. The base map was prepared from Survey of India's toposheets, the landuse map was prepared from indices techniques like normalised difference vegetation index (NDVI), normalised difference water index (NDWI), modified normalised difference water index (MNDWI), normalised difference pond index (NDPI), and normalized difference turbidity index (NDTI) in conjugation with visual interpretation. The soil moisture content map was reproduced from the soil atlas of Andaman and Nicobar Islands followed by generation of an aspect profile from ASTER-GDEM satellite data. Both the landuse map and aspect profile were validated for accuracy in the field. A weighted overlay analysis of the classes like landuse, soil moisture and aspect profile of the study area resulted in identification of the potential natural habitat map of malaria vector surrounding the areas of Tushnabad, Garacharma, Manglutan, Chouldari, Ferrargunj and Wimberlygunj hamlets. The natural habitat of malaria vector indicated that Tushnabad, Garacharma, Manglutan, Chouldari, Ferrargunj and Wimberlygunj hamlets are within the proximity of 2.5 km from the prime habitat location with more number of malaria positive cases. Also these hamlets are surrounded by dense evergreen forest and the land surface is draped by clay loam and clay soil texture exhibiting high soil moisture content warranting high rates of survival and proliferation of the vector ensuring resurgence of malaria every year. It is thus concluded that application of geospatial technologies plays an important role in identifying the natural

    2014-07-01

    Full Text Available The territories – cities and landscapes – of South Asia are under incredible transformation due to man-made and natural conditions. Globalisation is spatially leaving its imprint as cities and landscapes are progressively being built by an ever-more fragmented, piecemeal and ad-hoc project modus – funded by established and new-found fortunes of national and international developers and lenders, development aid projects and (often corrupt governments. At the same time, ‘natural’ disasters are increasing in severity and frequency – due to climate change and the flagrant disregard of the environment in the relentless dive to impose imported terms of reference for modernisation and urbanisation. The challenges and strategic importance of realising urban design in South Asia’s contemporary context of borrowed visions, abstract land-use planning and a diminishing political will are, obviously, innumerable. How to qualitatively intervene as an urbanist in such a context? This paper will argue that an understanding of contexts, based on fieldwork, is necessary in order to project feasible urban visions and strategic urban design projects that can make more evident particular sites’ inherent qualities and creatively marry ecological, infrastructural, and urbanisation issues by solutions that cut across multiple scales and sectoral divisions. Interpretative mapping is a first step to transform a territory. An understanding of the context and the reading of sites are necessary in order to create modifications that have logic and relate to the particularities of places and situations. Three scales of mapping (territorial, urban, and tissue will be presented. The territories/cities investigated are the southwest (Galle-Matara coast of Sri Lanka, Mumbai, the economic engine of India, and Khulna, the third largest city in Bangladesh.

    The Lower Ponnaiyar River Basin forms an important groundwater province in South India constituted by Tertiary formations dominated by sandstones and overlain by alluvium. The region enjoyed artesian conditions 50 years back but at present frequent failure of monsoon and over exploitation is threatening the aquifer. Further, extensive agricultural and industrial activities and urbanization has resulted in the increase in demand and contamination of the aquifer. To identify the sources and quality of groundwater, water samples from 47 bore wells were collected in an area of 154 km2 and were analysed for major ions and trace metals. The results reveal that the groundwater in many places is contaminated by higher concentrations of NO3, Cl, PO4 and Fe. Four major hydrochemical facies Ca-Mg-Cl, Na-Cl, Ca-HCO3 and Na-HCO3 were identified using Piper trilinear diagram. Salinity, sodium adsorption ratio, and sodium percentage indicate that most of the groundwater samples are not suitable for irrigation as well as for domestic purposes and far from drinking water standards. The most serious pollution threat to groundwater is from nitrate ions, which are associated with sewage and fertilizers application. The present state of the quality of the lower part of Ponnaiyar River Basin is of great concern and the higher concentration of toxic metals (Fe and Ni) may entail various health hazards.

    Full Text Available BRICS connotes five main emerging national economies: Brazil, Russia, India, China and South Africa are particularly distinguished as nations experiencing expanded market opportunities and countries discovered to be at stages of newly advanced economic development. This paper assesses the stock market development and economic growth in these BRICS nations. In doing this, quarterly time series data from 1994 to 2014 was sourced from World Bank Indicators. The Panel Generalized method based on the fixed effect estimation was employed to determine how stock market development affects the economic growth of BRICS. Diagnostic tests were conducted to ascertain the robustness and stability of the regression results after carrying out the unit root calculations. The findings reveal that stock market development exerts significant impact on the economic growth. The study further reveals that there was a positive correlation between stock market development indicators and BRICS’s economic growth. It is therefore proposed that the weaknesses of each of the BRICS member countries should be taken as policy focus and strategies necessary to strengthen them should be swiftly applied by their respective governments.

    To investigate the prevalence of malnutrition using anthropometric measures in a cohort of tribal students attending a school in rural south India. Children attending the school were offered three meals a day during attendance. Analysis of anthropometric data obtained aimed to determine the nutritional effect of the food provided. The nutritional status of 409 students were assessed by comparing anthropometric measurements to reference values according to WHO/NCHS guidelines. Height for age evaluation of the meals provided by the organisation. Four hundred and nine students were included for analysis in the study. The prevalence of thinness was 39.4 %. 59.5 % of 'new' and 52.9 % of 'old' students at the school demonstrated thinness. 59.4 % of students were classified as stunted. 73.8 % of 'new' students and 52.9 % of 'old' students demonstrated stunting (p 0.091). Significantly (p 0.010) more 'new' female students had stunted growth. Acute and chronic measures of malnutrition were high amongst adolescent students attending the school. Comparison of 'new' and 'old' adolescent pupils at the school hints that the 'old' students were less malnourished than their 'new' counterparts. This study demonstrates the importance for NGOs to develop their nutritional programmes with a special focus on adolescents.

    The lower blood lipid levels and lower incidence of coronary heart disease in fish eating populations has been attributed to the unusual n-3 fatty acids present in their fish diet. In order to test this hypothesis, a cross-sectional study was proposed to evaluate the lipid profile in free-living men and women of fish eating and non-fish eating populations aged between 20 to 70 years in coastal villages of the district of Nellore, in south India. The mean concentrations of total serum cholesterol and triacylglycerols were found to be lower in fish eating than in non-fish eating populations. Significant differences were observed between populations for certain age groups. The serum phospholipid content was lower in fish-eating than non-fish eating populations and the difference was found to be significant only for women. The mean total cholesterol and triacylglycerol levels were found elevated consistently as the age advanced in both sexes and populations. There were significant differences for blood lipids between men and women in some age groups. The percentile cut-off values for cholesterol and triacylglycerol were lower in fish eating as compared to non-fish eating group. Prevalence of hypercholesterolemia and hypertriglyceridemia (> or = 200 mg/dl) was significantly lower in fish eating people indicating less proneness to cardiovascular risk. The data indicate that eating of fish may have a role in ameliorating the risk of coronary heart disease. Copyright 2000 Harcourt Publishers Ltd.

    Deficiency of vitamin D has been associated with various health conditions. However, vitamin D deficiency (VDD) and factors associated with VDD are not well studied, especially among the urban elderly population of India. To assess the prevalence of VDD and its associated factors among the urban free-living elderly population in Hyderabad. A community-based cross-sectional study was conducted among 298 urban elderly (≥60 years) by adapting a random sampling procedure. Demographic particulars were collected. Blood pressure and anthropometric measurements were recorded using standard equipment. Fasting glucose, lipid profile and 25-hydroxy vitamin D [25(OH) D] were estimated in plasma samples. The mean ± SE plasma vitamin D and the prevalence of VDD among the urban elderly population were 19.3 ± 0.54 (ng/ml) and 56.3%, respectively. The prevalence of VDD was significantly associated with education, high body mass index (BMI), hypertension (HT) and metabolic syndrome (MS). Multiple logistic regression analysis revealed HT as a significant predictor of vitamin D deficiency and the risk of VDD was double among the elderly with hypertension. The prevalence of VDD was high among the urban elderly population in the south Indian city of Hyderabad. High BMI, MS, HT and education are significant associated factors of VDD.

    Autism spectrum disorder (ASD) affects about 1.4% of the population in South Asia but very few have access to any form of health care service. The objective of this study was to explore the beliefs and practices related to the care of children with ASD to inform strategies for intervention. In Pakistan, primary data were collected through in-depth interviews of parents (N = 15), while in India a narrative review of existing studies was conducted. The results show that the burden of care is almost entirely on the mother, leading to high levels of stress. Poor awareness of the condition in both family members and front-line health-providers leads to delay in recognition and appropriate management. There is considerable stigma and discrimination affecting children with autism and their families. Specialist services are rare, concentrated in urban areas, and inaccessible to the majority. Strategies for intervention should include building community and family support networks to provide respite to the main carer. In the absence of specialists, community members such as community health workers, traditional practitioners and even motivated family members could be trained in recognizing and providing evidence-based interventions. Such task-shifting strategies should be accompanied by campaigns to raise awareness so greater inclusivity can be achieved.

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

Cross sectional study. Dental outreach centre in Udupi District, Karnataka. 312 adults aged 35-44 years attending the centre. Face-to-face interview followed by oral health examination. The questionnaire in Kannada version of OIDP, perceived general and oral health and satisfaction with dental appearance were used. Reliability and Validity of OIDP instrument, Prevalence of oral impacts in study population. Majority of the participants (71.2%) reported oral health problems affecting at least one daily performance in the 6 months preceding the survey. The performance most affected was 'eating' (52.2%) followed by 'cleaning teeth' (32.4%). Cronbach's alpha for the OIDP frequency items was 0.70. Construct validity was proved by significant association of OIDP scores and self-rated oral, general health status and perceived satisfaction with appearance of teeth; with those more satisfied having fewer oral impacts (p Kannada version of OIDP had excellent psychometric properties for applicability among the adults in Karnataka. Thus, the study highlighted the limits of focusing exclusively on normative needs and suggested the incorporation of oral quality of life measures into the oral healthcare services.

    Technologies like mobile phones may not always work positively but they may have unforeseen adverse effects. This study was conducted to find the proportion of students who experienced ringxiety (phantom ringing) and other perceived effects, as well as the pattern of the mobile phone usage among college students. A cross-sectional study was carried out at Kasturba Medical College, Mangalore, south India, among 336 medical students by using a pre-tested, semi-structured questionnaire. Among the total number of students, 335 students possessed mobile phones. Mostly, the persons whom they talked to on their phones were parents for 220 (51%) of the students. 48% (150) talked for less than half hour in a day and 41% (137) were high volume message users. "Ringxiety" was experienced by 34.5% (116) of the students and they were more likely to use their phones at restricted places like classrooms (99%) and libraries (60.3%). A significantly larger proportion of ringxiety sufferers also complained of hampered studies. The pattern of mobile phone use among the medical students appeared to be problematic, as a fairly large proportion suffered from ringxiety, they reported getting very upset and they used their phones at restricted times and places. This problem needs to be recognized, all stakeholders must be made aware of the symptoms and measures must be taken to reduce it.

    Full Text Available Introduction: Globally, billions of people do not have access to improved sanitation and many defecate in the open air. Poor hand washing practices and limited access to sanitation facilities perpetuate the transmission of disease-causing germs. The objectives of the study were to find out the level of knowledge, attitudes, and practices (KAPs on sanitary latrine, footwear, and hand washing among rural people and to assess the improvement in KAP after health education intervention. Materials and Methods: A health education intervention study was conducted from November 2012 to January 2014 in a rural area of Kuppam, Andhra Pradesh, South India among the people aged 15 years and above. The individuals were selected by multistage random sampling and interviewed using a structured questionnaire. After a baseline KAP assessment, intervention activities were conducted twice. The intervention activities were group level talks and discussions, free soap distribution, and display of posters at anganwadi centers. Post-KAP was assessed twice, and the significance of difference was found by using McNemar′s test. Results: After the intervention, there was a significant improvement in the overall KAPs among the subjects in post test-1 and post test-2 (P1 < 0.0001, P2 < 0.0001, respectively. Conclusions: Health education as an intervention has significantly increased KAP more than 30%. Hence, it is imperative that education interventions are needed to bring or sustain positive change.

    Full Text Available Background: Panton Valentine Leukocidin (PVL toxin, responsible for increased virulence and more severe infections can be found in both Methicillin-sensitive and Methicillin-resistant strains of Staphylococcus aureus (MSSA and MRSA. Aims & Objectives: To generate baseline data on the extent of MRSA infections and to estimate the frequency of PVL-positive S.aureus in Belgaum, South India. Material & Methods: 70 clinical isolates of S.aureus were obtained from various laboratories in Belgaum city. Theseisolates were identified, phenotypically characterized as MRSA/MSSA by disc diffusion method using oxacillin discs (1 µg and genetically by multiplex PCR for mecA and fem B genes. PCR was subsequently carried out on all isolates to detect LukS-PV and LukF-PV genes, the markers for potential producers of PVL toxin. Results: 27 out of 70 isolates (38.6% were confirmed as MRSA by PCR formecA. The prevalence of PVL gene was 85.1% and 48.8% in MRSA and MSSA respectively. The overall prevalence of PVL positive S.aureuswas 62.85%. Conclusion: Our study showed high percentage of PVL positive MRSA and MSSA, higher than the most reports worldwide. In the backdrop of bacterial strains gaining multiple drug resistance, our study warrants further epidemiological studies in hospitals and community levels in the region.
