Land development without thoughtful water supply planning can lead to unsustainability. In practice, management of our lands and waters is often unintegrated. We present new land-use, ecological stream health, water quality, and streamflow data from nine perennial watersheds in the Kathmandu Valley, Nepal, in the 2016 monsoon (i.e., August and September) and 2017 pre-monsoon (i.e., April and May) periods. Our goal was to improve understanding of the longitudinal linkages between land-use and water. At a total of 38 locations, the Rapid Stream Assessment (RSA) protocol was used to characterize stream ecology, basic water quality parameters were collected with a handheld WTW multi-parameter meter, and stream flow was measured with a SonTek FlowTracker Acoustic Doppler Velocimeter. A pixel-based supervised classification method was used to create a 30-m gridded land use coverage from a Landsat 8 image scene captured in the fall of 2015. Our results indicated that land-use had a statistically significant impact on water quality, with built land-uses (high and low) having the greatest influence. Upstream locations of six of the nine watersheds investigated had near natural status (i.e., river quality class (RQC) 1) and water could be used for all purposes (after standard treatments as required). However, downstream RSA measurements for all nine watersheds had RQC 5 (i.e., most highly impaired). Generally, water quality deteriorated from monsoon 2016 to pre-monsoon 2017. Our findings reinforce the importance of integrated land and water management and highlight the urgency of addressing waste management issues in the Kathmandu Valley.

Immunization is one of the most effective health interventions averting an estimated 2-3 million deaths every year. In Nepal, as in most low-income countries, infants are immunized with standard WHO recommended vaccines. However, 16.4 % of children did not receive complete immunization by 12 months of age in Nepal in 2011. Studies from different parts of the world showed that incomplete immunization is even higher in slums. The objective of this study was to identify the predictors of incompletion of immunization among children aged 12-23 months living in the slums of Kathmandu Valley, Nepal. The unmatched case-control study was conducted in 22 randomly selected slums of Kathmandu Valley. The sampling frame was first identified by complete enumeration of entire households of the study area from which 59 incompletely immunized children as cases and 177 completely immunized children as controls were chosen randomly in 1:3 ratio. Data were collected from the primary caretakers of the children. Backward logistic regression with 95 % confidence interval and adjusted odds ratio (AOR) were applied to assess the factors independently associated with incomplete immunization. Twenty-six percent of the children were incompletely vaccinated. The coverage of BCG vaccine was 95.0 % while it was 80.5 % for measles vaccine. The significant predictors of incomplete immunization were the home delivery of a child, the family residing on rent, a primary caretaker with poor knowledge about the schedule of vaccination and negative perception towards vaccinating a sick child, conflicting priorities, and development of abscess following immunization. Reduction of abscess formation rate can be a potential way to improve immunization rates. Community health volunteers should increase their follow-up on children born at home and those living in rent. Health institutions and volunteers should be influential in creating awareness about immunization, its schedule, and post-vaccination side

Female Sex Workers (FSWs) are main drivers of the HIV epidemic in Nepal. The work environment of sex work in Nepal is differentiated into establishment based (e.g. massage parlors, dance restaurants, hotels and lodges) and street based (e.g. streets, parks and markets). The study compares HIV, syphilis and risk behaviours among establishment-based FSWs and street-based FSWs in Kathmandu Valley of Nepal. Cross-sectional bio-behavioral surveys in 2006, 2008, 2011 and 2015 aimed to sample 2093 FSWs using two stage cluster sampling in the Kathmandu valley. Statistical analysis used chi-squared tests and logistic regression models to assess differences of HIV, syphilis and risk behaviors among street-based FSWs and establishment-based FSWs. The study included 39.7% street-based FSWs and 60.3% establishment-based FSWs. The street-based FSWs had lower education levels, older age groups, separated, longer duration of sex work and inconsistent condom used with clients than establishment-based FSWs (p<0.05). Establishment-based FSWs were lower exposure to HIV intervention programs and pervasive alcohol consumption and use of drugs (p<0.05). The multivariate analysis showed that street-based FSWs were more likely of HIV test (aOR=1.25, 95%CI=1.04, 1.49), HIV (aOR=4.72, 95%CI=2.19, 10.15) and syphilis (aOR=7.96, 95%CI=3.49, 18.15) than establishment-based FSWs. Street-based FSWs possessed higher risk behaviour and have higher HIV and syphilis prevalence. HIV prevention interventions targeting FSWs should consider risks and vulnerability of street-based FSWs. .

Groundwater quality is a critical problem in Kathmandu Valley, Nepal. The population of the city increased 6 times in the last six decades and more than half of water demand depends on groundwater resource. Nevertheless, few data of microorganism presence have been reported qualitatively in the central area of the valley. We investigated distribution of faecal indicator bacteria (Total coliforms and Escherichia coli) detected in wells and analyzed the variations of the concentrations. Groundwater samples were collected from 12 deep tube wells (170-300m depths) and 36 shallow tube wells and dug wells (3-20m depths) in Aug 2008, Jan 2009, Aug 2009 and Aug 2010. River waters were also collected for analyzing effect on groundwater quality. E. coli was detected from most of all wells; the concentrations were within 1 log cfu/100mL in deep tube wells and shallow tube wells while those in dug wells ranged from 1 to 3 log cfu/100mL. E. coli was detected at extremely high level in river water, from 5 to 7 log cfu/100mL, however, no clear relation was observed between E. coli concentrations in any types of groundwaters and distance of wells from adjacent rivers. These results indicate that both types of tube wells were rather protected and dug wells were most vulnerable for faecal contamination at very local scale. Genetic analysis of bacterial communities for deep well samples showed the existence of Enterobacter, Acinetobacter as well as Methane-metabolizing groups which provide information of possible indicators other than total coliforms or E. coli for groundwater management in the valley.

Anthropogenic emissions of carbon dioxide and methane - key greenhouse gases (GHGs) - are primary causes of global warming and resultant impacts. The atmospheric warming is more pronounced and likely to cause more serious damage in vulnerable areas such as the Hindukush-Karakorum-Himalayan region (HKH). The HKH region is a data gap region according to the 5th Assessment report of the intergovernmental panel on climate change (IPCC). In order to understand the mixing ratios and variability of the key GHGs in the foothills of the Central Himalaya, we carried out continuous measurements of CO2, CH4, CO, and water vapor at Bode (an urban site in the Kathmandu valley, Nepal) for a year (March 2013 - Feb 2014), and again at Bode and at Chanban (a background outside the Valley) for 3 months (July 15 - Oct 3, 2015), with two state-of-the-art cavity ring-down instruments (Picarro G2401). The measurements were carried out as a part of the international air pollution measurement campaign: SusKat- ABC (Sustainable atmosphere for the Kathmandu Valley - Atmospheric Brown Clouds). The annual average CO2 and CH4 concentrations at Bode were 419 ± 24 and 2.192 ± 0.224 ppm, respectively, which are notably higher than those observed at the background site at Mauna Loa Observatory in the same period. The CO2concentration at Bode was high during the pre-monsoon period and low during the monsoon, while CH4 was high in winter and lower during the pre-monsoon period. The monthly CO2concentration was highest in April. Forest fires and agro-waste burning in the region, and the local emissions in the Kathmandu valley were the main sources of the high CO2 in the pre-monsoon period. CH4 showed a maximum in September due to additional emissions from paddy fields. Seasonally, winter has the highest CH4 concentration which is due to brick production, which is a seasonal activity, and other local sources combined with the shallow mixing layer height in winter. The diurnal pattern of CO2 and CH4

Despite extensive distribution of free condoms and lubricants to prevent HIV transmission among men having sex with men (MSM) in Nepal, the prevalence of HIV and risky sexual behaviors remain high. The influence of individual-level, social-capital, and social-structural factors on HIV risk has been insufficiently explored in MSM. The authors assessed association of these factors with HIV risk among 150 MSM enrolled using snowball sampling in the Kathmandu Valley. HIV risk was calculated on the basis of number and type of sexual partners and condom use during anal sex. Multivariate analysis showed a high risk of HIV infection was significantly associated with being involved in sex work, having no knowledge of male sexually transmitted infection (STI) symptoms, and having a history of STI symptoms. HIV prevention could be made more effective by targeting MSM who are involved in sex work and by improving their knowledge of male STI symptoms and early diagnosis and treatment.

Depression is emerging as a highly prevalent psychiatric condition among people living with HIV/AIDS (PLWHA). Perceived family support (PFS) buffers depression among chronic disease patients. However, a similar relationship among PLWHA is unexplored. To examine the relationship between PFS and depression among PLWHA in the Kathmandu Valley, Nepal. In this cross-sectional study, depression was measured by Beck Depression Inventory Ia. Perceived family support was measured by Nepali Family Support and Difficulties Scale. The status of depression was compared between 208 PLWHA and 208 HIV-negative participants. The relationship between PFS and depression was examined only among PLWHA. Among each of the 208 participants, the number of depressed PLWHA (n = 61,29.3%) was higher than that of HIV-negative participants (n = 13,6.2%; P < .001). Perceived family support had a negative association with depression in PLWHA (adjusted odds ratio [AOR] = 0.20, 95% confidence interval [CI] = 0.08-0.53). In Nepal, PLWHA display a higher level of depression than HIV-negative people, and a lower level of PFS is associated with depression among PLWHA. Improved family support might be helpful in reducing depression among Nepalese PLWHA.

With growing urbanization, traffic has become one of the main sources of air pollution in Nepal. Understanding the impact of air pollution on health requires estimation of exposure. Land use regression (LUR) modeling is widely used to investigate intraurban variation in air pollution for Western cities, but LUR models are relatively scarce in developing countries. In this study, we developed LUR models to characterize intraurban variation of nitrogen dioxide (NO 2 ) in urban areas of Kathmandu Valley, Nepal, one of the fastest urbanizing areas in South Asia. Over the study area, 135 monitoring sites were selected using stratified random sampling based on building density and road density along with purposeful sampling. In 2014, four sampling campaigns were performed, one per season, for two weeks each. NO 2 was measured using duplicate Palmes tubes at 135 sites, with additional information on nitric oxide (NO), NO 2 , and nitrogen oxide (NOx) concentrations derived from Ogawa badges at 28 sites. Geographical variables (e.g., road network, land use, built area) were used as predictor variables in LUR modeling, considering buffers 25-400m around each monitoring site. Annual average NO 2 by site ranged from 5.7 to 120ppb for the study area, with higher concentrations in the Village Development Committees (VDCs) of Kathmandu and Lalitpur than in Kirtipur, Thimi, and Bhaktapur, and with variability present within each VDC. In the final LUR model, length of major road, built area, and industrial area were positively associated with NO 2 concentration while normalized difference vegetation index (NDVI) was negatively associated with NO 2 concentration (R 2 =0.51). Cross-validation of the results confirmed the reliability of the model. The combination of passive NO 2 sampling and LUR modeling techniques allowed for characterization of nitrogen dioxide patterns in a developing country setting, demonstrating spatial variability and high pollution levels.

Semicontinuous PM2. 5 and black carbon (BC) concentrations, and 24 h integrated PM2. 5 filter samples were collected near roadways in the Kathmandu Valley, Nepal. Instruments were carried by a group of volunteer traffic police officers in the vicinity of six major roadway intersections in the Kathmandu Valley across two sampling periods in 2014. Daily PM2. 5 filter samples were analyzed for water-soluble inorganic ions, elemental carbon (EC) and organic carbon (OC), and 24 elements. Mean PM2. 5 and BC concentrations were 124.76 µg m-3 and 16.74 µgC m-3 during the drier spring sampling period, and 45.92 µg m-3 and 13.46 µgC m-3 during monsoonal sampling. Despite the lower monsoonal PM2. 5 concentrations, BC and several elements were not significantly lower during the monsoon, which indicates an important contribution of vehicle-related emissions throughout both seasons in this region. During the monsoon, there was an enhanced contribution of chemical species (elements and water-soluble inorganic ions), except secondary inorganic ions, and BC to PM2. 5 (crustal elements: 19 %; heavy metals: 5 %; and BC: 39 %) compared to those in spring (crustal elements: 9 %; heavy metals: 1 %; and BC: 18 %). Silica, calcium, aluminum, and iron were the most abundant elements during both spring and the monsoon, with total concentrations of 12.13 and 8.85 µg m-3, respectively. PM2. 5 and BC showed less spatial variation compared to that for individual chemical species.

Nepal is not an exception to alcohol use; urban poor are more prone than the general population. The question of social consequences of alcohol use among urban poor remains largely unanswered in Nepal. Study explored the alcohol linked social consequences among the urban poor of Kathmandu Valley. Taking 422 urban poor from four squatter settlements of Kathmandu Valley, a cross-sectional study was carried out. A series of univariate and bivariate analysis were performed in R version 3.1.2. Four out of 10 current drinkers (42.86%, 95% CI: 31.4-54.3) encountered various social consequences. The number one consequence hitting 23.19% drinkers was money loss. Male drinkers were 4.43 times (95% CI: 1.810.8) more likely to face social consequences than their female counterparts. Being male frequent drinker increased the odds of social consequence 3.80 times (95% CI:1.3-11.0) than that of female frequent drinker. A behaviour change communication campaign needs initiation; male populace and frequent drinkers being the target.

The paper presents a comparative study of the 3 most used solar PV module technologies in Nepal, which are Si-mono-crystalline, Si-poly-crystalline and Si-amorphous. The aim of the paper is to present and discuss the recorded Global Solar Radiation, received in the Kathmandu valley by three different, Si-mono-crystalline, Si-poly-crystalline and Si-amorphous calibrated solar cell pyranometers and to propose the best-suited solar PV module technology for roof top solar PV systems inside the Kathmandu valley. Data recorded over the course of seven months, thus covering most of the seasonal meteorological conditions determining Kathmandu valley's global solar radiation reception are presented. The results indicate that the Si-amorphous pyranometer captured 1.56% more global solar radiation than the Si-mono-crystalline and 18.4% more than Si-poly-crystalline pyranometer over the course of seven months. Among the three pyranometer technologies the maximum and minimum cell temperature was measured by the Si-mono-crystalline pyranometer. Following the technical data and discussion, an economical analysis, using the versatile software tool PVSYST V5.01is used to calculate the life cycle costs of a 1kW roof top solar PV RAPS system, with battery storage, and a 1kW roof top solar PV grid connected system with no energy storage facility, through simulations, using average recorded global solar radiation data for the KTM valley and investigated market values for each solar PV module and peripheral equipment costs.

Objective To assess the associations between diarrhoea and types of water sources, total quantity of water consumed and the quantity of improved water consumed in rapidly growing, highly populated urban areas in developing countries. Design Cross-sectional analysis using population-representative secondary data obtained from an interview survey conducted by the Asian Development Bank for the 2009 Kathmandu Valley Water Distribution, Sewerage and Urban Development Project. Setting Kathmandu Valley, Nepal. Participants 2282 households. Methods A structured questionnaire was used to collect information from households on the quantity and sources of water consumed; health, socioeconomic and demographic status of households; drinking water treatment practices and toilet facilities. Results Family members of 179 households (7.8%) reported having developed diarrhoea during the previous month. For households in which family members consumed less than 100 L of water per capita per day (L/c/d), which is the minimum quantity recommended by WHO, the risk of contracting diarrhoea doubled (1.56-fold to 2.92-fold). In households that used alternative water sources (such as wells, stone spouts and springs) in addition to improved water (provided by a water management authority), the likelihood of contracting diarrhoea was 1.81-fold higher (95% CI 1.00 to 3.29) than in those that used only improved water. However, access to an improved water source was not associated with a lower risk of developing diarrhoea if optimal quantities of water were not consumed (ie, <100 L/c/d). These results were independent of socioeconomic and demographic variables, daily drinking water treatment practices, toilet facilities and residential areas. Conclusions Providing access to a sufficient quantity of water—regardless of the source—may be more important in preventing diarrhoea than supplying a limited quantity of improved water.

This paper investigates two complementary pieces of data on households' demand for improved water services, coping costs and willingness to pay (WTP), from a survey of 1500 randomly sampled households in Kathmandu, Nepal. We evaluate how coping costs and WTP vary across types of water users and income. We find that households in Kathmandu Valley engage in five main types of coping behaviors: collecting, pumping, treating, storing, and purchasing. These activities impose coping costs on an average household of as much as 3 U.S. dollars per month or about 1% of current incomes, representing hidden but real costs of poor infrastructure service. We find that these coping costs are almost twice as much as the current monthly bills paid to the water utility but are significantly lower than estimates of WTP for improved services. We find that coping costs are statistically correlated with WTP and several household characteristics.

The properties and the vertical structure of the mixing layer as part of the planetary boundary layer are of key importance for local air quality. They have a substantial impact on the vertical dispersion of pollutants in the lower atmosphere and thus on their concentrations near the surface. In this study, ceilometer measurements taken within the framework of the SusKat project (Sustainable Atmosphere for the Kathmandu Valley) are used to investigate the mixing layer height in the Kathmandu Valley, Nepal. The applied method is based on the assumption that the aerosol concentration is nearly constant in the vertical and distinctly higher within the mixing layer than in the air above. Thus, the height with the steepest gradient within the ceilometer backscatter profile marks the top of the mixing layer. Ceilometer and black carbon (BC) measurements conducted from March 2013 through February 2014 provide a unique and important dataset for the analysis of the meteorological and air quality conditions in the Kathmandu Valley. In this study the mean diurnal cycle of the mixing layer height in the Kathmandu Valley for each season (pre-monsoon, monsoon, post-monsoon and winter season) and its dependency on the meteorological situation is investigated. In addition, the impact of the mixing layer height on the BC concentration is analyzed and compared to the relevance of other important processes such as emissions, horizontal advection and deposition. In all seasons the diurnal cycle is typically characterized by low mixing heights during the night, gradually increasing after sun rise reaching to maximum values in the afternoon before decreasing again. Seasonal differences can be seen particularly in the height of the mixing layer, e.g. from on average 153/1200 m (pre-monsoon) to 241/755 m (monsoon season) during the night/day, and the duration of enhanced mixing layer heights during daytime (around 12 hours (pre-monsoon season) to 8 hours (winter)).

To assess diarrhoeal risks from enteropathogenic Escherichia coli, Giardia and Cryptosporidium from consuming raw spinach, cabbage, carrots and tomatoes in Kathmandu Valley, Nepal. The annual infection risk was quantified using the probabilistic Quantitative Microbial Risk Assessment approach, which considered 12 vegetable washing combinations. A new model was used to estimate dose of pathogens per exposure comprising parameters such as pathogen concentration in vegetable wash water before selling and eating, vegetable consumption rate, remaining pathogen ratio after washing, remaining water on vegetables after washing and water treatment removal efficiency. When all washing combinations were considered, high infection risks above the acceptable level of -4 log 10 infection per person per year were obtained, whereas the risk was reduced when other sources excluding river water were used. Assuming use of water treated with ceramic filters by all consumers, a 0-2 log 10 reduction in the estimated risks was obtained, which was insufficient to achieve the required risk level. High risk of diarrhoea prevails among raw vegetable consumers in the valley. It is needed to protect vegetable washing water sources and establish advanced water treatment methods to achieve the required level of public health risk. © 2017 The Society for Applied Microbiology.

Rapid urban growth is a process which can be observed in cities worldwide. Managing these growing urban areas has become a major challenge for both governing bodies and citizens. Situated not only in a highly earthquake and landslide-prone area, but comprising also the cultural and political capital of Nepal, the fast expanding Kathmandu Valley in the Himalayan region is of particular interest. Vulnerability assessment has been an important tool for spatial planning in this already densely populated area. The magnitude 8.4 earthquake of Bihar in 1934 cost 8600 Nepalis their lives, destroyed 20% of the Kathmandu building stock and heavily damaged another 40%. Since then, Kathmandu has grown into a hub with over a million inhabitants. Rapid infrastructure and population growth aggravate the vulnerability conditions, particularly in the core area of Metropolitan Kathmandu. We propose an integrative framework for vulnerability and risk in Kathmandu Valley. In order to move towards a more systemic and integrated approach, we focus on interactions between natural hazards, physically engineered systems and society. High resolution satellite images are used to identify structural vulnerability of the building stock within the study area. Using object-based image analysis, the spatial dynamics of urban growth are assessed and validated using field data. Complementing this is the analysis of socio-economic attributes gained from databases and field surveys. An indicator-based vulnerability and resilience index will be operationalized using multi-attribute value theory and statistical methods such as principal component analysis. The results allow for a socio-economic comparison of places and their relative potential for harm and loss. The objective in this task is to better understand the interactions between nature and society, engineered systems and built environments through the development of an interdisciplinary framework on systemic seismic risk and vulnerability.

Although groundwater is a major water supply source in the Kathmandu Valley of Nepal, it is known that the groundwater has significant microbial contamination exceeding the drinking water quality standard recommended by the World Health Organization (WHO), and that this has been implicated in causing a variety of diseases among people living in the valley. However, little is known about the distribution of pathogenic microbes in the groundwater. Here, we analysed the microbial communities of the six water samples from deep tube wells by using the 16S rRNA gene sequences based culture-independent method. The analysis showed that the groundwater has been contaminated with various types of opportunistic microbes in addition to fecal microbes. Particularly, the clonal sequences related to the opportunistic microbes within the genus Acinetobacter were detected in all samples. As many strains of Acinetobacter are known as multi-drug resistant microbes that are currently spreading in the world, we conducted a molecular-based survey for detection of the gene encoding carbapenem-hydrolysing β-lactamase (bla(oxa-23-like) gene), which is a key enzyme responsible for multi-drug resistance, in the groundwater samples. Nested polymerase chain reaction (PCR) using two specific primer sets for amplifying bla(oxa-23-like) gene indicated that two of six groundwater samples contain multi-drug resistant Acinetobacter.

We make and analyze structural damage observations from within the Kathmandu valley following the 2015 M7.8 Gorkha, Nepal earthquake to derive macroseismic intensities at several locations including some located near ground motion recording sites. The macroseismic intensity estimates supplement the limited strong ground motion data in order to characterize the damage statistics. This augmentation allows for direct comparisons between ground motion amplitudes and structural damage characteristics and ultimately produces a more constrained ground shaking hazard map for the Gorkha earthquake. For systematic assessments, we focused on damage to three specific building categories: (a) low/mid-rise reinforced concrete frames with infill brick walls, (b) unreinforced brick masonry bearing walls with reinforced concrete slabs, and (c) unreinforced brick masonry bearing walls with partial timber framing. Evaluating dozens of photos of each construction type, assigning each building in the study sample to a European Macroseismic Scale (EMS)-98 Vulnerability Class based upon its structural characteristics, and then individually assigning an EMS-98 Damage Grade to each building allows a statistically derived estimate of macroseismic intensity for each of nine study areas in and around the Kathmandu valley. This analysis concludes that EMS-98 macroseismic intensities for the study areas from the Gorkha mainshock typically were in the VII–IX range. The intensity assignment process described is more rigorous than the informal approach of assigning intensities based upon anecdotal media or first-person accounts of felt-reports, shaking, and their interpretation of damage. Detailed EMS-98 macroseismic assessments in urban areas are critical for quantifying relations between shaking and damage as well as for calibrating loss estimates. We show that the macroseismic assignments made herein result in fatality estimates consistent with the overall and district-wide reported values.

We make and analyze structural damage observations from within the Kathmandu valley following the 2015 M7.8 Gorkha, Nepal earthquake to derive macroseismic intensities at several locations including some located near ground motion recording sites. The macroseismic intensity estimates supplement the limited strong ground motion data in order to characterize the damage statistics. This augmentation allows for direct comparisons between ground motion amplitudes and structural damage characteristics and ultimately produces a more constrained ground shaking hazard map for the Gorkha earthquake. For systematic assessments, we focused on damage to three specific building categories: (a) low/mid-rise reinforced concrete frames with infill brick walls, (b) unreinforced brick masonry bearing walls with reinforced concrete slabs, and (c) unreinforced brick masonry bearing walls with partial timber framing. Evaluating dozens of photos of each construction type, assigning each building in the study sample to a European Macroseismic Scale (EMS)-98 Vulnerability Class based upon its structural characteristics, and then individually assigning an EMS-98 Damage Grade to each building allows a statistically derived estimate of macroseismic intensity for each of nine study areas in and around the Kathmandu valley.

Intimate partner violence (IPV) is an urgent public health priority. It is a neglected issue in women's health, especially in urban slums in Nepal and globally. This study was designed to better understand the IPV experienced by young pregnant women in urban slums of the Kathmandu Valley, as well as to identify their coping strategies, care and support seeking behaviours. Womens' views on ways to prevent IPV were also addressed. 20 young pregnant women from 13 urban slums in the Kathmandu valley were recruited purposively for this qualitative study, based on pre-defined criteria. In-depth interviews were conducted and transcribed, with qualitative content analysis used to analyse the transcripts. 14 respondents were survivors of violence in urban slums. Their intimate partner(s) committed most of the violent acts. These young pregnant women were more likely to experience different forms of violence (psychological, physical and sexual) if they refused to have sex, gave birth to a girl, or if their husband had alcohol use disorder. The identification of foetal gender also increased the experience of physical violence at the prenatal stage. Interference from in-laws prevented further escalation of physical abuse. The most common coping strategy adopted to avoid violence among these women was to tolerate and accept the husbands' abuse because of economic dependence. Violence survivors sought informal support from their close family members. Women suggested multiple short and long term actions to reduce intimate partner violence such as female education, economic independence of young women, banning identification of foetal gender during pregnancy and establishing separate institutions within their community to handle violence against young pregnant women. Diversity in the design and implementation of culturally and socially acceptable interventions might be effective in addressing violence against young pregnant women in humanitarian settings such as urban slums.

An evaluation of the meteorology simulated using the Weather Research and Forecast (WRF) model for the region of south Asia and Nepal with a focus on the Kathmandu Valley is presented. A particular focus of the model evaluation is placed on meteorological parameters that are highly relevant to air quality such as wind speed and direction, boundary layer height and precipitation. The same model setup is then used for simulations with WRF including chemistry and aerosols (WRF-Chem). A WRF-Chem simulation has been performed using the state-of-the-art emission database, EDGAR HTAP v2.2, which is the Emission Database for Global Atmospheric Research of the Joint Research Centre (JRC) of the European Commission, in cooperation with the Task Force on Hemispheric Transport of Air Pollution (TF HTAP) organized by the United Nations Economic Commission for Europe, along with a sensitivity simulation using observation-based black carbon emission fluxes for the Kathmandu Valley. The WRF-Chem simulations are analyzed in comparison to black carbon measurements in the valley and to each other. The evaluation of the WRF simulation with a horizontal resolution of 3×3 km2 shows that the model is often able to capture important meteorological parameters inside the Kathmandu Valley and the results for most meteorological parameters are well within the range of biases found in other WRF studies especially in mountain areas. But the evaluation results also clearly highlight the difficulties of capturing meteorological parameters in such complex terrain and reproducing subgrid-scale processes with a horizontal resolution of 3×3 km2. The measured black carbon concentrations are typically systematically and strongly underestimated by WRF-Chem. A sensitivity study with improved emissions in the Kathmandu Valley shows significantly reduced biases but also underlines several limitations of such corrections. Further improvements of the model and of the emission data are needed before being

Limited information is available on the prevalence of waterborne pathogens in aquatic environments in developing countries. In this study, water samples were collected from nine shallow wells and a river in the Kathmandu Valley, Nepal, during the rainy season in 2009 and were subjected to detection of waterborne protozoa, viruses and coliphages using a recently developed method for simultaneous concentration of protozoa and viruses in water. Escherichia coli and total coliforms were also tested as indicator bacteria. At least one type of the five pathogens tested (Cryptosporidium, Giardia, human adenoviruses, and noroviruses of genogroups I and II) was detected in five groundwater samples (56%) (1000 ml each) from shallow wells. Compared with groundwater samples, the pathogens were more abundant in the river water sample (100ml); the concentrations of Cryptosporidium and Giardia were 140 oocysts/l and 8500 cysts/l, respectively, and the mean threshold cycle (Ct) values in real-time RT-PCR were 34.3, 36.8 and 34.0 for human adenoviruses and noroviruses of genogroups I and II, respectively. Genotyping of F-RNA coliphages by real-time RT-PCR was successfully used to differentiate human and animal faecal contamination in the samples. Moreover, for the groundwater samples, protozoa and viruses were detected only in E. coli-positive samples, suggesting that E. coli may be an appropriate indicator of pathogen contamination of valley groundwater.

Bacteriological analysis of drinking water leads to detection of only conventional fecal indicator bacteria. This study aimed to explore and characterize bacterial diversity, to understand the extent of pathogenic bacterial contamination, and to examine the relationship between pathogenic bacteria and fecal indicator bacteria in different water sources in the Kathmandu Valley, Nepal. Sixteen water samples were collected from shallow dug wells (n=12), a deep tube well (n=1), a spring (n=1), and rivers (n=2) in September 2014 for 16S rRNA gene next-generation sequencing. A total of 525 genera were identified, of which 81 genera were classified as possible pathogenic bacteria. Acinetobacter, Arcobacter, and Clostridium were detected with a relatively higher abundance (>0.1% of total bacterial genes) in 16, 13, and 5 of the 16 samples, respectively, and the highest abundance ratio of Acinetobacter (85.14%) was obtained in the deep tube well sample. Furthermore, the bla OXA23-like genes of Acinetobacter were detected using SYBR Green-based quantitative PCR in 13 (35%) of 37 water samples, including the 16 samples that were analyzed for next-generation sequencing, with concentrations ranging 5.3-7.5logcopies/100mL. There was no sufficient correlation found between fecal indicator bacteria, such as Escherichia coli and total coliforms, and potential pathogenic bacteria, as well as the bla OXA23-like gene of Acinetobacter. These results suggest the limitation of using conventional fecal indicator bacteria in evaluating the pathogenic bacteria contamination of different water sources in the Kathmandu Valley.

Sustainable urban housing in Kathmandu, Nepal: Proposals and evaluations

NASA Astrophysics Data System (ADS)

Shrestha, Vikas

Kathmandu Valley represents one of the oldest cultural hubs in the Himalayas. The historic towns in the valley consist of densely built traditional Chowk and Bahal houses with enclosed courtyards. With exposure to the outside world since 1951, the western style single-family detached house has become an image of the modern home and a status symbol. In the context of the exploding population, the prevailing trend of these free standing houses have exacerbated urban sprawl and led to inefficient use of the limited agricultural land in the valley. Devoid of shared open spaces, the new settlements lack play areas for children, places for social gathering and a sense of community. Building materials that are not manufactured locally must be trucked from India over the mountains. So is coal for the production of brick and cement, and diesel for transportation. Minimizing the amount of imported materials and energy used by these modern houses will reduce the environmental impact and also benefit the national economy. Kathmandu enjoys clear sky conditions during winter that makes passive solar design a potential strategy to achieve thermal comfort and eliminate kerosene heaters with their harmful effects. The abundance of rainfall during monsoon season makes rainwater collection a viable supplement to the unreliable municipal water supply. This dissertation creates three new housing prototypes that address all these issues. These prototypes are modern interpretations of the vernacular Chowk and Bahal, which create communal open space by grouping rowhouses around a common courtyard. Combining vernacular wisdom with the principles of sustainable design, these prototypes reduce land consumption; reduce resource consumption; create community open space; minimize imported materials; increase energy efficiency and thermal comfort; make homes and neighborhoods self sustainable for water supply and wastewater treatment; and altogether improve the quality of life.

Assessment of environmental policy implementation in solid waste management in Kathmandu, Nepal.

PubMed

Dangi, Mohan B; Schoenberger, Erica; Boland, John J

2017-06-01

In Nepal, full-fledged environmental legislation was rare before the democratic constitution of 1990. The first law covering the environment and sustainability was the Environment Protection Act 1997. While the Solid Waste Act was introduced in 1987, the problem of solid waste management still surfaces in Kathmandu. In order to understand the bedrock of this unrelenting failure in solid waste management, the manuscript digs deeper into policy implementation by dissecting solid waste rules, environmental legislations, relevant local laws, and solid waste management practices in Kathmandu, Nepal. A very rich field study that included surveys, interviews, site visits, and literature review provided the basis for the article. The study shows that volumes of new Nepalese rules are crafted without effective enforcement of their predecessors and there is a frequent power struggle between local government bodies and central authority in implementing the codes and allocating resources in solid waste management. The study concludes that Kathmandu does not require any new instrument to address solid waste problems; instead, it needs creation of local resources, execution of local codes, and commitment from central government to allow free exercise of these policies.

2018-03-01

In this study, the prevalence of various waterborne pathogens in water samples collected in the Kathmandu Valley, Nepal, and the applicability of Escherichia coli as an indicator of pathogen contamination in groundwater were assessed. Fifty-three water samples, including shallow groundwater and river water, were analyzed to examine the presence of protozoan (oo)cysts via fluorescence microscopy and that of viral and bacterial genomes via quantitative PCR. At least one of the seven types of pathogens tested (i.e., Cryptosporidium, Giardia, human adenoviruses, noroviruses of genogroups I and II, group A rotaviruses, and Vibrio cholerae) was detected in 68% (15/22) of the shallow dug well water samples; groundwater in the shallow dug wells was more contaminated compared with that in shallow tube wells (8/15, 53%). River water and sewage samples were contaminated with extremely high concentrations of multiple pathogens, whereas a tap water sample supplied by a water tanker tested positive for human adenoviruses and V. cholerae. The detection of host-specific Bacteroidales genetic markers revealed the effects of human and animal feces on groundwater contamination. The tested pathogens were sometimes detected even in E. coli-negative groundwater samples, indicative of the limitations of using E. coli as an indicator for waterborne pathogens in groundwater.

DOC and DON Dynamics along the Bagmati Drainage Network in Kathmandu Valley

Bhatt, M. P.; McDowell, W. H.

2005-05-01

We studied organic matter dynamics and inorganic chemistry of the Bagmati River in Kathmandu valley, Nepal, to understand the influence of human and geochemical processes on chemical loads along the drainage system. Population density appears to be the most fundamental control on the chemistry of surface waters within the Bagmati drainage system. DOC concentration increases 10-fold with distance downstream (from 2.38 to 23.95 mg/L) and shows a strong relationship with human population density. The composition of river water (nutrients, Cl) suggests that sewage effluent to the river has a major effect on water quality. Concentrations were highest during summer, and lowest during the winter monsoon season. In contrast to DOC, DON concentration shows surprisingly little variation, and tends to decrease in concentration with distance downstream. Ammonium contributes almost all nitrogen in the total dissolved nitrogen fraction and the concentration of nitrate is negligible, probably due to rapid denitrification within the stream channel under relatively low-oxygen conditions. Decreases in sulfate along the stream channel may also be due to the reduction of sulfate to sulfide due to the heavy organic matter loading. Water quality is unacceptable for any use and the whole ecosystem is severely affected within the urban areas. Based on a comparison of downstream and upstream water quality, it appears that human activities along the Bagmati, principally inputs of human sewage, are largely responsible for the changes in surface water chemistry within Kathmandu valley.

Motivating people in rapidly urbanizing areas to take protective actions against natural disasters faces the challenge that these people often do not know what actions to take, do not believe that such actions are effective, and/or believe that the disaster will not happen to them within their lifetimes. Thus, finding demonstrated ways of motivating people to take protective action likely constitutes a grand challenge for natural disaster risk reduction and resiliency, because it may be one of the largest, lowest-cost sources of potential risk reduction in these situations. We developed a theory-based documentary film (hereafter, intervention) targeted at motivating retrofits of local school buildings, and tested its effectiveness in Kathmandu, Nepal, using a matched-pair clustered randomized controlled trial. The intervention features Nepalese who have strengthened their school buildings as role models to others at schools still in need of seismic work. It was tested at 16 Kathmandu Valley schools from November 2014 through March 2015. Schools were matched into 8 pairs, then randomly assigned to see either the intervention film or an attention placebo control film on an unrelated topic. Testing was completed just five weeks before the M 7.8 Gorkha earthquake struck central Nepal. When compared to the control schools, the schools whose community members saw the retrofit intervention film increased their knowledge of specific actions to take in support of earthquake-resistant construction, belief in the feasibility of making buildings earthquake-resistant, willingness to support seismic strengthening of the local school building, and likelihood to recommend to others that they build earthquake-resistant homes, which have all been shown to be precursors to taking self-protective action. This suggests that employing a mass-media intervention featuring community members who have already taken the desired action increases factors that may accelerate adoption of risk

Our knowledge about ambient black carbon (BC) in the vast Himalayan region, a region vulnerable to impacts of global warming, is very limited due to unavailability of a long-term ambient monitoring. Here we present results from a continuous monitoring of ambient BC concentrations, with a new generation Aethalometer (AE33), over a three year period (January 2013- January 2016) at a semi-urban site in the highly polluted Kathmandu Valley in the foothills of the central Himalaya, one of the most polluted cities in the world. This is the longest time series of BC concentrations that have been monitored with AE33 (which uses the dual-spot technique for a real-time filter loading compensation) in highly polluted ambient environment. The measurements were carried out under the framework of project SusKat (Sustainable Atmosphere for the Kathmandu Valley). BC concentrations were found to be extremely high, especially in winter and the pre-monsoon period, with the hourly-averaged values often exceeding 50 μg/m3. BC concentrations showed a clear diurnal cycle with a prominent peak around 8-9 am and a second peak around 8-9 pm local time in all four seasons. Night-time BC was also fairly high. The diurnal cycle was driven by a combination of increased emissions from traffic, cooking activities, garbage burning, and lower mixing heights (˜200 m) and reduced horizontal ventilation in the mornings and evenings. BC concentrations showed significant seasonal variations - a maximum in winter season and minimum during the monsoon (rainy) season, with monthly average values in the range 5-30 μg/m3. An increase in emissions from the operation of over 100 brick kilns in winter and spring, and an increase in the use of small but numerous diesel power generators during hours with power cuts contributed significantly to ambient BC concentrations in the valley. Fractional contributions of biomass burning and fossil fuel combustion to BC was estimated based on a real-time method for

Light-absorbing Aerosol Properties in the Kathmandu Valley during SusKat-ABC Field Campaign

Light-absorbing aerosols, such as black carbon (BC), are major contributors to the atmospheric heating and the reduction of solar radiation reaching at the earth's surface. In this study, we investigate light-absorption and scattering properties of aerosols (i.e., BC mass concentration, aerosol solar-absorption/scattering efficiency) in the Kathmandu valley during Sustainable atmosphere for the Kathmandu valley (SusKat)-ABC campaign, from December 2012 to February 2013. Kathmandu City is among the most polluted cities in the world. However, there are only few past studies that provide basic understanding of air pollution in the Kathmandu Valley, which is not sufficient for designing effective mitigation measures (e.g., technological, financial, regulatory, legal and political measures, planning strategies). A distinct diurnal variation of BC mass concentration with two high peaks observed during wintertime dry monsoon period. BC mass concentration was found to be maximum around 09:00 and 20:00 local standard time (LST). Increased cars and cooking activities including substantial burning of wood and other biomass in the morning and in the evening contributed to high BC concentration. Low BC concentrations during the daytime can be explain by reduced vehicular movement and cooking activities. Also, the developmements of the boundary layer height and mountain-valley winds in the Kathmandu Valley paly a crucial role in the temproal variation of BC mass concentrations. Detailed radiative effects of light-absorbing aerosols will be presented.

Objective. This study aimed to assess the prevalence and associated factors of hypertension in newly declared municipalities of Kathmandu, Nepal. Design, Settings, and Participants. This was a community-based cross-sectional study conducted in the municipalities of Kathmandu District, Nepal, between January and July 2015. Study participants were aged 18 to 70 years, residing permanently in the study sites. Municipalities, Wards, households, and respondents were selected randomly. Results. Of the 587 participants, 58.8% were females, mean (SD) age was 42.3 (13.5) years, 29.3% had no formal education, 35.1% were Brahmins, and 41.2% were homemakers. Prevalence of hypertension was 32.5% (95% CI: 28.7–36.3). Age, gender, education, ethnicity, occupation, smoking, alcohol consumption, physical activity, diabetes, menopausal history, and family history of cardiovascular disease (CVD) and hypertension were significantly associated with hypertension. In multivariable analysis, smoking, alcohol consumption, physical activity, body mass index, and diabetes were identified as significant explanatory variables for hypertension. Conclusion. This study demonstrated that the people living in newly established municipalities of Kathmandu, Nepal, have a high burden of hypertension as well as its associated factors. Therefore, community-based preventive approaches like lifestyle modification and early detection and treatment of hypertension might bring a substantial change in tackling the burden effectively.

Nepal has experienced sporadic reports of human rights violations among sexual and gender minorities. Our objective was to identify a range of human rights that are enshrined in international law and/or are commonly reported by sexual and gender minority participants in Kathmandu, to be nonprotected or violated. In September 2009 three focus group discussions were conducted by trained interviewers among a convenience sample of sexual and gender minority participants in Kathmandu Nepal. The modified Delphi technique was utilized to elicit and rank participant-generated definitions of human rights and their subsequent violations. Data was analyzed independently and cross checked by another investigator. Participants (n = 29) reported experiencing a range of human rights violations at home, work, educational, health care settings and in public places. Lack of adequate legal protection, physical and mental abuse and torture were commonly reported. Access to adequate legal protection and improvements in the family and healthcare environment were ranked as the most important priority areas. Sexual and gender minorities in Nepal experienced a range of human rights violations. Future efforts should enroll a larger and more systematic sample of participants to determine frequency, timing, and/or intensity of exposure to rights violations, and estimate the population-based impact of these rights violations on specific health outcomes.

The SusKat-ABC (Sustainable Atmosphere for the Kathmandu Valley-Atmospheric Brown Clouds) international air pollution measurement campaign was carried out from December 2012 to June 2013 in the Kathmandu Valley and surrounding regions in Nepal. The Kathmandu Valley is a bowl-shaped basin with a severe air pollution problem. This paper reports measurements of two major greenhouse gases (GHGs), methane (CH4) and carbon dioxide (CO2), along with the pollutant CO, that began during the campaign and were extended for 1 year at the SusKat-ABC supersite in Bode, a semi-urban location in the Kathmandu Valley. Simultaneous measurements were also made during 2015 in Bode and a nearby rural site (Chanban) ˜ 25 km (aerial distance) to the southwest of Bode on the other side of a tall ridge. The ambient mixing ratios of methane (CH4), carbon dioxide (CO2), water vapor, and carbon monoxide (CO) were measured with a cavity ring-down spectrometer (G2401; Picarro, USA) along with meteorological parameters for 1 year (March 2013-March 2014). These measurements are the first of their kind in the central Himalayan foothills. At Bode, the annual average mixing ratios of CO2 and CH4 were 419.3 (±6.0) ppm and 2.192 (±0.066) ppm, respectively. These values are higher than the levels observed at background sites such as Mauna Loa, USA (CO2: 396.8 ± 2.0 ppm, CH4: 1.831 ± 0.110 ppm) and Waliguan, China (CO2: 397.7 ± 3.6 ppm, CH4: 1.879 ± 0.009 ppm) during the same period and at other urban and semi-urban sites in the region, such as Ahmedabad and Shadnagar (India). They varied slightly across the seasons at Bode, with seasonal average CH4 mixing ratios of 2.157 (±0.230) ppm in the pre-monsoon season, 2.199 (±0.241) ppm in the monsoon, 2.210 (±0.200) ppm in the post-monsoon, and 2.214 (±0.209) ppm in the winter season. The average CO2 mixing ratios were 426.2 (±25.5) ppm in the pre-monsoon, 413.5 (±24.2) ppm in the monsoon, 417.3 (±23.1) ppm in the post-monsoon, and 421.9 (±20

Technologies and activities of the on-road traffic fleets, including bus, van, 3-wheeler, taxi and motorcycle (MC) in the Kathmandu Valley, Nepal, during 2010, were investigated with the aim to produce emission estimates, using the International Vehicle Emission (IVE) model, for the base year and for an optimistic technology scenario. The parking lot survey, GPS monitoring and video camera monitoring were conducted over four typical road types (arterial, highway, residential and outskirt roads). The average age of vehicles in the bus, van, 3-wheeler, taxi and MC fleet was 9, 8.7, 11, 9.5 and 4 years, respectively. There were some extremely old buses (over 40 years old) which had extremely high emission factors. Except for MCs that had a large share of Euro III technology (75%), other types of surveyed vehicles were at most Euro II or lower. The average vehicle kilometers traveled (VKT) for each vehicle type was estimated based on odometer readings which showed comparable results with the GPS survey. The emission factors (EFs) produced by the IVE model for the driving and meteorological conditions in Kathmandu were used to estimate emissions for the base case of 2010. EFs in Kathmandu were higher than other developing cities, especially for PM and NOx from the bus fleet. Diurnal variations of the emissions were consistent with the diurnal vehicle density. From the fleet in 2010, total emissions of the major pollutants, i.e., CO, VOC, NOx, PM, BC, and CO2, were 31, 7.7, 16, 4.7, 2.1, and 1554 Gg, respectively. If the entire fleet in the Kathmandu Valley would comply with Euro III then the emission would decrease, as compared to the base case, by 44% for toxic air pollutants (excluding CO2) and 31% for climate-forcers in terms of the 20-year horizon CO2-equivalent. Future surveys should include other vehicle types such as trucks, personal cars, and non-road vehicles. The EFs obtained for the Euro III scenario in Kathmandu were well above those in other parts of the

Background Depression and suicidal thinking occur frequently alongside HIV/AIDS, triggering profound detrimental impacts on quality of life, treatment adherence, disease progression, and mortality. Yet the psychosocial factors contributing to these psychiatric comorbidities remain underexplored, particularly in the developing country context. This study thus examined different dimensions of perceived family support in relation to depression and suicidal ideation among people living with HIV/AIDS (PLWHA) in Nepal. Methods A cross-sectional survey of 322 adult PLWHA residing in the Kathmandu Valley, Nepal was conducted. Data were analyzed using multiple logistic regressions for correlates of Beck Depression Inventory (BDI)-Ia-defined depressive symptoms and suicidal ideation in the past 2 weeks.

Depression and suicidal thinking occur frequently alongside HIV/AIDS, triggering profound detrimental impacts on quality of life, treatment adherence, disease progression, and mortality. Yet the psychosocial factors contributing to these psychiatric comorbidities remain underexplored, particularly in the developing country context. This study thus examined different dimensions of perceived family support in relation to depression and suicidal ideation among people living with HIV/AIDS (PLWHA) in Nepal. A cross-sectional survey of 322 adult PLWHA residing in the Kathmandu Valley, Nepal was conducted. Data were analyzed using multiple logistic regressions for correlates of Beck Depression Inventory (BDI)-Ia-defined depressive symptoms and suicidal ideation in the past 2 weeks. Perceived family support, measured using the 10-item Nepali Family Support and Difficulty Scale, was entered into separate models, in turn, as a composite score, for each sub-scale (emotional, instrumental, and negative support), and for each individual item. Overall, 25.5% of participants registered BDI-Ia-defined depression, with significantly lower rates among those with perceived family support scores in the highest (AOR = 0.19; 95% CI = 0.07, 0.55) and middle (AOR = 0.38; 95% CI = 0.17, 0.86) tertiles relative to those with lowest-tertile scores.

Human rights violations among sexual and gender minorities in Kathmandu, Nepal: a qualitative investigation

PubMed Central

2012-01-01

Background Nepal has experienced sporadic reports of human rights violations among sexual and gender minorities. Our objective was to identify a range of human rights that are enshrined in international law and/or are commonly reported by sexual and gender minority participants in Kathmandu, to be nonprotected or violated. Methods In September 2009 three focus group discussions were conducted by trained interviewers among a convenience sample of sexual and gender minority participants in Kathmandu Nepal. The modified Delphi technique was utilized to elicit and rank participant-generated definitions of human rights and their subsequent violations. Data was analyzed independently and cross checked by another investigator. Results Participants (n = 29) reported experiencing a range of human rights violations at home, work, educational, health care settings and in public places. Lack of adequate legal protection, physical and mental abuse and torture were commonly reported. Access to adequate legal protection and improvements in the family and healthcare environment were ranked as the most important priority areas. Conclusions Sexual and gender minorities in Nepal experienced a range of human rights violations. Future efforts should enroll a larger and more systematic sample of participants to determine frequency, timing, and/or intensity of exposure to rights violations, and estimate the population-based impact of these rights violations on specific health outcomes PMID:22591775

Unusual lightning events have been observed in Uppsala, Sweden, and Kathmandu, Nepal, using essentially the same electric field measuring system developed at Uppsala University. They occurred in the storms that also generated ;normal; lightning events. The unusual events recorded in Uppsala occurred on one thunderstorm day. Similar events were observed in Kathmandu on multiple thunderstorm days. The unusual events were analyzed in this study assuming them to be positive ground flashes (+CGs), although we cannot rule out the possibility that some or most of them were actually cloud discharges (ICs). The unusual events were each characterized by a relatively slow, negative (atmospheric electricity sign convention) electric field waveform preceded by a pronounced opposite-polarity pulse whose duration was some tens of microseconds. To the best of our knowledge, such unusual events have not been reported in the literature. The average amplitudes of the opposite-polarity pulses with respect to those of the following main waveform were found to be about 33% in Uppsala (N = 31) and about 38% in Kathmandu (N = 327). The average durations of the main waveform and the preceding opposite-polarity pulse in Uppsala were 8.24 ms and 57.1 μs, respectively, and their counterparts in Kathmandu were 421 μs and 39.7 μs. Electric field waveforms characteristic of negative ground flashes (-CGs) were also observed, and none of them exhibited an opposite-polarity pulse prior to the main waveform. Possible origins of the unusual field waveforms are discussed.

On 25 April 2015, the Gorkha earthquake of magnitude 7.8, severely damaged the cultural heritage sites of Nepal. In particular, the seven monument zones of the Kathmandu Valley World Heritage Site suffered extensive damage. Out of 195 surveyed monuments, 38 have completely collapsed and 157 partially damaged (DoA, 2015). In particular, the world historic city of Bhaktapur was heavily affected by the earthquake. There is, in general, a lack of knowledge regarding the traditional construction technology used in many of the most important temple monuments in Bhaktapur. To address this limitation and to assist in reconstruction and rehabilitation of the area, this study documents the existing condition of different historic structures in the Kathmandu Valley. In particular, the Nyatapola Temple is studied in detail. To record and document the condition of this temple, a combination of laser scanning and terrestrial and aerial photogrammetry are used. By also including evaluation of the temple and its supporting plinth structure using non-destructive evaluation techniques like geo-radar and micro-tremor dynamic analysis, this study will form the basis of a structural analysis study to assess the anticipated future seismic performance of the Nyatapola Temple.

To investigate the effects of unequal supply hours on consumers' coping strategies and perceptions of the intermittent water supply (IWS) in the Kathmandu Valley (KV), Nepal we conducted a randomized household survey (n=369) and on-site water quality tests. Half of the households received piped water for 6 or fewer hours per week. To augment or cope with the inadequate supply, 28% of the households used highly contaminated and expensive tanker-delivered water. Half of the piped water samples (n=13) were contaminated with Escherichia coli. Free chlorine concentration in all piped water samples was below the national standards (0.1-0.2mg/L), but combined chlorine was detected at an average of 0.24mg/L, indicating ingression of contaminants in the network. Point-of-use devices could increase access to safe water in the KV from 42% to 80%. The use of Lorenz curves and Gini coefficients revealed inequality of piped water supply hours per week both between and within service areas in the KV, due mainly to a small percentage of households who receive longer supply hours. To cope with reduced supply hours, home owners pay more to get water from alternative sources, while tenants compromise their water consumption. Under IWS, expectations for improvements in piped water quality and supply regularity are higher than those for supply volume. Consumers' perceptions of the piped water services worsen with the reduction in supply hours, but perceptions of piped water tariff are independent of supply hours. Copyright © 2017 Elsevier B.V.

Young children are at greatest risk of exposure to lead and its effects. Although lead is one of the most widely used elements with known health hazard, there is little data on the blood lead level (BLL) of children in the Kathmandu Valley. Thus, this study aimed to assess factors associated with high BLL in children who were 6–36 months of age and resided in the Kathmandu Valley. In this hospital-based cross-sectional study 6–36 month-old children visiting the Paediatrics Outpatient Department of Tribhuvan University Teaching Hospital, Patan Hospital, and Siddhi Memorial Hospital were enrolled. All three hospitals are located in different areas inside the Kathmandu Valley. Written informed consent was obtained from the parents, and exposure data were collected using a structured questionnaire. Portable Anodic Stripping Voltammetry (ASV) was used to determine BLLs in children. Data were analyzed using SPSS version 16. Of 312 children enrolled in the study, 64.4% had BLLs ≥5μg/dl. A significant association was found between BLL and exposure to enamel paints in the household in the form of painting materials used in different parts of the house like walls, windows and doors (p = 0.001). Furthermore, multivariate analyses showed that BLLs were 4.5 times higher in children playing with dirt and dust (p = 0.006) and that children belonging to the community of lower caste/ethnicity groups had significantly higher BLLs compared to those from the upper caste groups (p = 0.02). Our study demonstrated that children living in households that have used enamel paints, children belonging to lower caste/ethnic groups, and children frequently playing with dirt and dust had significantly higher BLLs. The results of this study highlight the importance of policy decisions to limit environmental lead contamination, and to roll out awareness building measures designed to limit lead exposure and break the poverty cycle associated with chronic lead poisoning.

Spine surgery in Nepal: the 2015 earthquake

PubMed Central

2015-01-01

At noon on Saturday, 25 April 2015, a 7.8 magnitude earthquake struck Nepal. It was centered in the Himalaya northwest of Kathmandu, the capital of over 1 million people. The violent tremors were felt as far away as New Delhi, India 1,000 km from the epicenter, but the worst of its destructive force was experienced in the heavily populated Kathmandu valley and in the remote mountainous villages of the Himalaya. Ancient temples crumbled; poorly constructed buildings collapsed; men, women, and children were trapped and injured, sometimes fatally. Avalanches killed mountain climbers, Sherpa guides, and porters at Everest base camp (EBC). The death toll to date exceeds 8,600 with as many as 20,000 injured. Spinal Health International (SHI), a nonprofit volunteer organization, has been active in Nepal in past years and responded to requests by Nepali spine surgeons for assistance with traumatic spine injury victims following the earthquake. SHI volunteers were present during the 2nd major earthquake of magnitude 7.3 on 12 May 2015. Past and current experiences in Nepal will be presented. PMID:27683676

More than 1.5 million people live in the Kathmandu valley. The valley is facing an extreme shortage of water supply. At the same time the demand is escalating rapidly. To address this issue of scarcity of water, the government of Nepal has proposed a project of inter-basin transfer of water from Melamchi River located 40 km north-east of the Kathmandu valley. The project will cover two districts and three municipalities and will potentially have significant impacts on the environment. In accordance with the Environmental Protection Regulation of Nepal (1997), the Melamchi Water Supply Project (MWSP) has undergone an EIA during the feasibility study stage of the proposed project. The recommendations contained in the EIA were integrated into the project design for implementation in 2006. This paper summarizes the background of MWSP, the environmental concerns described in the EIA and the status of Environmental Management Plan (EMP) developed to address environmental compliance and other issues involving participation and support of the local people. This paper also provides some lessons to learn on the modalities of addressing the demands and grievances of the local people concerning environmental management.

Overview of Nepal's energy sources and environment

NASA Astrophysics Data System (ADS)

Sharma, C. K.

In the Kathmandu Valley, Nepal faces environmental problems of most industrialized countries whereas it has problems similar to the least developed countries, in the hills. Types and quantity of energy use have a close link with the environmental degradation in Nepal Himalaya. Over dependence on the forest to meet the energy demand in the hills has aggravated the environmental problems. Lack of forest cover on the hills, the intense monsoon rain, the fragile geology and steep terrain are contributing to the acceleration of landslides, soil erosion and temperature rise. The rise of average minimum temperature is causing glaciers to retreat and thereby the development of large bodies of glacial lake. Glacial lake outbursts of 1981 in Kodari and of 1985 in Namche bazar area caused extensive damage on infrastructures down stream. Heavy use of commercial fuel (hydrocarbons) in the bowl shaped Kathmandu valley is causing air and water pollution and an increase in the average minimum temperature. Extensive development of hydropower, biogas plants and massive reforestation on naked hills and efficient use of imported hydrocarbons are the solution to existing energy and environmental problems.

Ground motions from the 2015 Mw 7.8 Gorkha, Nepal, earthquake constrained by a detailed assessment of macroseismic data

To augment limited instrumental recordings of the Mw 7.8 Gorkha, Nepal, earthquake on 25 April 2015 (Nepali calendar: 12 Baisakh 2072, Bikram Samvat), we collected 3831 detailed media and first-person accounts of macroseismic effects that include sufficiently detailed information to assign intensities. The resulting intensity map reveals the distribution of shaking within and outside of Nepal, with the key result that shaking intensities throughout the near-field region only exceeded intensity 8 on the 1998 European Macroseismic Scale (EMS-98) in rare instances. Within the Kathmandu Valley, intensities were generally 6–7 EMS. This surprising (and fortunate) result can be explained by the nature of the mainshock ground motions, which were dominated by energy at periods significantly longer than the resonant periods of vernacular structures throughout the Kathmandu Valley. Outside of the Kathmandu Valley, intensities were also generally lower than 8 EMS, but the earthquake took a heavy toll on a number of remote villages, where many especially vulnerable masonry houses collapsed catastrophically in 7–8 EMS shaking. We further reconsider intensities from the 1833 earthquake sequence and conclude that it occurred on the same fault segment as the Gorkha earthquake.

Waste stream characteristics must be understood to tackle waste management problems in Kathmandu Metropolitan City (KMC), Nepal. Three-stage stratified cluster sampling was used to evaluate solid waste data collected from 336 households in KMC. This information was combined with data collected regarding waste from restaurants, hotels, schools and streets. The study found that 497.3 g capita(-1) day(-1) of solid waste was generated from households and 48.5, 113.3 and 26.1 kg facility(-1) day(-1) of waste was generated from restaurants, hotels and schools, respectively. Street litter measured 69.3 metric tons day(-1). The average municipal solid waste generation rate was 523.8 metric tons day(-1) or 0.66 kg capita(-1) day(-1) as compared to the 320 metric tons day(-1) reported by the city. The coefficient of correlation between the number of people and the amount of waste produced was 0.94. Key household waste constituents included 71% organic wastes, 12% plastics, 7.5% paper and paper products, 5% dirt and construction debris and 1% hazardous wastes. Although the waste composition varied depending on the source, the composition analysis of waste from restaurants, hotels, schools and streets showed a high percentage of organic wastes. These numbers suggest a greater potential for recovery of organic wastes via composting and there is an opportunity for recycling. Because there is no previous inquiry of this scale in reporting comprehensive municipal solid waste generation in Nepal, this study can be treated as a baseline for other Nepalese municipalities.

A cross sectional study was carried out on 78 screened cataract patients of two screening camps in Kathmandu valley, Nepal, to assess the willingness to pay for cataract surgery. A non-probability sampling technique with open ended and close ended questionnaires was used. The average age of patients was 68.8 years. The ratio of men and women was 0.9:1. 42.3% (33) of patients were willing to pay for cataract surgery. Among them 48.5% (16) of people were willing to pay less than dollars 13 and 51.5% (17) were willing to pay more than dollars 13. The mean was dollars 2.3 (SD dollars 15.5) per case. Patients with bilateral cataract were more willing to pay than unilateral cases. Poverty (44.4%, 20) was the main barrier for unwillingness to pay for cataract surgery. Other reasons were the lack of family support (28.9%, 13), lack of knowledge of surgery and belief that it was an unnecessary procedure (15.6%, seven), and waiting for a free surgical service (11.1%, five). This study clearly indicates that although there was awareness of the availability of treatment and services provided within the reach, people are not willing to pay for the surgery and use the facility primarily because of poverty. Hence, to change patients' attitudes, a more holistic approach is needed, keeping in view the cultural, social, and economic background of the society.

Cross-sectional serosurvey of avian influenza antibodies presence in domestic ducks of Kathmandu, Nepal.

Kathmandu, Nepal has been classified as a high-risk area for highly pathogenic avian influenza (HPAI) by the Nepali Government. While ducks have an important role in the transmission of avian influenza viruses (AIV), including HPAI, seroprevalence of antibodies to AIV in domestic ducks of Kathmandu has never been assessed. The objectives of this study were (i) to estimate the prevalence of seroconversion to AIV in domestic ducks in major duck-raising areas of Kathmandu and (ii) to assess the effect of age, sex, presence of swine and the number of ducks on the farm on the carriage of antibodies to AIV in these ducks. From April through July of 2011, a cross-sectional study was conducted and a total of 310 ducks in the major duck-raising areas of Kathmandu were sampled. The estimated prevalence of AIV antibodies was 27.2% [95% confidence interval (CI): 24.6-29.5]. Of 62 enrolled farms, 42% had at least one seropositive duck. Half of the enrolled farms also kept pigs of which 52% had at least one seropositive duck. Bivariate analysis indicated association between ducks' seroconversion to AIV and their age, sex and farm size. However, the final multivariable model, after controlling for clustering of ducks within farms, identified age as the only significant risk factor. Based on this model, ducks older than 1 year of age were more likely to be seropositive compared to ducks <6 months of age [odds ratio = 2.17 (1.07-4.39)]. These results provide baseline information about the AIV seroprevalence in domestic ducks in the major duck-raising areas of Kathmandu and identify a high-risk group that can be targeted in surveillance activities. Future studies should be conducted to differentiate the subtypes of AIV present among domestic ducks in Kathmandu, with particular interest in the presence of HPAI viruses. © 2014 Blackwell Verlag GmbH.

Background: An occupational hazard contributes to severe health problems among workers due to unhygienic conditions and lack of safety at the workplace. Economic growth and productivity can be well achieved by promoting health, safety, and improved quality workplace. Aims: To assess the knowledge of occupational hazards, use of Personal Protective Equipment (PPE) and the factors associated with awareness on occupational hazards among automobile repair artisans in Kathmandu, Nepal. Settings and Design: A quantitative descriptive cross-sectional study with 400 automobile repair artisans from Kathmandu metropolitan city was conducted between March and September, 2015. Materials and Methods: Simple random sampling was adopted for recruiting study participants. Pre-tested, validated semi-structured questionnaire was used in line with study objectives to collect the data. Statistical Analysis: Logistic regression analysis was employed to identify factors associated with the awareness of occupational hazard and PPE use. Results: Of total, 56% had awareness on occupational hazard and 44.3% of artisans were using the personal protective equipments. Being educated, having job duration ≥6 years and having pre-service training for work were significantly associated with the awareness of occupational hazards. Notably, we found that those who were aware of occupational hazard (OR = 3.01, 95% CI: 1.98–4.57) were three times more likely to use the safety measures when compared to those who were unaware. Conclusions: Awareness on occupational hazard and use of PPE is very low among automobile repair artisans in Kathmandu, Nepal. Therefore, interventions on awareness raising on areas, like provision of pre-service training, promotion of safety advocacy, and enforcement of appropriate regulations for work place. PMID:29743786

The Himalayan collision zone experiences many seismic activities with large earthquakes occurring at certain time intervals. The damming of the proto-Bagmati River as a result of rapid mountain-building processes created a lake in the Kathmandu Valley that eventually dried out, leaving thick unconsolidated lacustrine deposits. Previous studies have shown that the sediments are 600 m thick in the center. A location in a seismically active region, and the possible amplification of seismic waves due to thick sediments, have made Kathmandu Valley seismically vulnerable. It has suffered devastation due to earthquakes several times in the past. The development of the Kathmandu Valley into the largest urban agglomerate in Nepal has exposed a large population to seismic hazards. This vulnerability was apparent during the Gorkha Earthquake (Mw7.8) on April 25, 2015, when the main shock and ensuing aftershocks claimed more than 1700 lives and nearly 13% of buildings inside the valley were completely damaged. Preparing safe and up-to-date building codes to reduce seismic risk requires a thorough study of ground motion amplification. Characterizing subsurface velocity structure is a step toward achieving that goal. We used the records from an array of strong-motion accelerometers installed by Hokkaido University and Tribhuvan University to construct 1-D velocity models of station sites by forward modeling of low-frequency S-waves. Filtered records (0.1-0.5 Hz) from one of the accelerometers installed at a rock site during a moderate-sized (mb4.9) earthquake on August 30, 2013, and three moderate-sized (Mw5.1, Mw5.1, and Mw5.5) aftershocks of the 2015 Gorkha Earthquake were used as input motion for modeling of low-frequency S-waves. We consulted available geological maps, cross-sections, and borehole data as the basis for initial models for the sediment sites. This study shows that the basin has an undulating topography and sediment sites have deposits of varying thicknesses

The Kathmandu Valley in Nepal suffers from severe wintertime air pollution. Volatile organic compounds (VOCs) are key constituents of air pollution, though their specific role in the Valley is poorly understood due to insufficient data. During the SusKat-ABC (Sustainable Atmosphere for the Kathmandu Valley-Atmospheric Brown Clouds) field campaign conducted in Nepal in the winter of 2012-2013, a comprehensive study was carried out to characterize the chemical composition of ambient Kathmandu air, including the determination of speciated VOCs by deploying a Proton Transfer Reaction Time of Flight Mass Spectrometer (PTR-TOF-MS)-the first such deployment in South Asia. 71 ion peaks (for which measured ambient concentrations exceeded the 2 σ detection limit) were detected in the PTR-TOF-MS mass scan data, highlighting the chemical complexity of ambient air in the Valley. Of the 71 species, 37 were found to have campaign average concentrations greater than 200 ppt and were identified based on their spectral characteristics, ambient diel profiles and correlation with specific emission tracers as a result of the high mass resolution (m/Δm > 4200) and temporal resolution (1 min) of the PTR-TOF-MS. The highest average VOC mixing ratios during the measurement period were (in rank order): acetaldehyde (8.8 ppb), methanol (7.4 ppb), acetone (4.2 ppb), benzene (2.7 ppb), toluene (1.5 ppb), isoprene (1.1 ppb), acetonitrile (1.1 ppb), C8-aromatics (~ 1 ppb), furan (~ 0.5 ppb), and C9-aromatics (0.4 ppb). Distinct diel profiles were observed for the nominal isobaric compounds isoprene (m/z = 69.070) and furan (m/z = 69.033). Comparison with wintertime measurements from several locations elsewhere in the world showed mixing ratios of acetaldehyde (~ 9 ppb), acetonitrile (~ 1 ppb) and isoprene (~ 1 ppb) to be among the highest reported till date. Two "new" ambient compounds namely, formamide (m/z = 46.029) and acetamide (m/z = 60.051), which can photochemically produce isocyanic

The access to essential medicines for non-communicable disease treatment is unacceptably low worldwide. The fundamental right to health cannot be fulfilled without equitable access to essential medicines. A cross-sectional study was carried out in 94 community pharmacies of Kathmandu valley. Non-probability quota sampling method was adopted for the purpose. Village Development Committees with more than 5000 populations were included in the study. The availability of the selected essential medicines, their price and producer identity were observed. Data entry and analysis were carried out in Microsoft Excel and Statistical package for social science. The availability of the essential medicines was not 100% in Kathmandu valley. High competition and high price variation were seen in metformin 500 mg (254.6%) and atorvastatin 10 mg (327.6%). The study showed that maximum (54.7%) brands were manufactured in Nepal. Furthermore, atorvastatin 10 mg (0.6 day wage) was found to be quite expensive, and glibenclamide 5 mg (0.1 day wage) was the cheapest one for diabetes mellitus treatment for 1 month of treatment period compared to daily wages of other essential medicines. The availability of the selected essential medicines was found to be ununiform and insufficient in the entire region. High competition was observed in the products with high price variation, and the access to cost-effective brand was poor. Furthermore, it was found that government salary is affordable to treat non-communicable disease with the help of the essential medicines.

Abstract Commercially produced complementary foods can help improve nutritional status of young children if they are appropriately fortified and of optimal nutrient composition. However, other commercially produced snack food products may be nutritionally detrimental, potentially increasing consumption of foods high in salt or sugar and displacing consumption of other more nutritious options. Helen Keller International, in collaboration with the Nepal government, implemented a study to assess mothers' utilization of commercial food products for child feeding and exposure to commercial promotions for these products. A cross‐sectional survey was conducted among 309 mothers of children less than 24 months of age across 15 health facilities. Utilization of breastmilk substitutes was low, having been consumed by 6.2% of children 0–5 months of age and 7.5% of children 6–23 months of age. Approximately one‐fourth (24.6%) of children 6–23 months age had consumed a commercially produced complementary food in the prior day. Twenty‐eight percent of mothers reported observing a promotion for breastmilk substitutes, and 20.1% reported promotions for commercially produced complementary foods. Consumption of commercially produced snack food products was high at 74.1% of children 6–23 months. Promotions for these same commercially produced snack food products were highly prevalent in Kathmandu Valley, reported by 85.4% of mothers. In order to improve diets during the complementary feeding period, development of national standards for complementary food products is recommended. Nutritious snack options should be promoted for the complementary feeding period; consumption of commercially produced snack food products high in sugar and salt and low in nutrients should be discouraged.

Hazardous child labor in Nepal is a serious concern, particularly in the brick kiln industry. Although a range of interventions have been implemented in Nepal to address hazardous child labor, there is a lack of research to both measure success and shape further development in interventions that integrate sound child protection practices to ensure the wellbeing of all children. This paper provides a review of the literature outlining interventions for children working in brick kilns in Nepal, and presents preliminary case study findings of one current intervention in the Kathmandu Valley. The paper highlights the strength of applying foundational child protection principles and advocates for the development and implementation of future programs underpinned by broad civil society principles within a child rights and protection framework.

In 2013, some landslides induced by heavy rainfalls occurred in southern part of Kathmandu, Nepal which is located southern suburb of Kathmandu, the capital. These landslide slopes hit by the strong Gorkha Earthquake in April 2015 and seemed to destabilize again. Hereby, to clarify their susceptibility of landslide in the earthquake, one of these landslide slopes was analyzed its slope stability by CSSDP (Critical Slip Surface analysis by Dynamic Programming based on limit equilibrium method, especially Janbu method) against slope failure with various seismic acceleration observed around Kathmandu in the Gorkha Earthquake. The CSSDP can detect the landslide slip surface which has minimum Fs (factor of safety) automatically using dynamic programming theory. The geology in this area mainly consists of fragile schist and it is prone to landslide occurrence. Field survey was conducted to obtain topological data such as ground surface and slip surface cross section. Soil parameters obtained by geotechnical tests with field sampling were applied. Consequently, the slope has distinctive characteristics followings in terms of slope stability: (1) With heavy rainfall, it collapsed and had a factor of safety Fs <1.0 (0.654 or more). (2) With seismic acceleration of 0.15G (147gal) observed around Kathmandu, it has Fs=1.34. (3) With possible local seismic acceleration of 0.35G (343gal) estimated at Kathmandu, it has Fs=0.989. If it were very shallow landslide and covered with cedars, it could have Fs =1.055 due to root reinforcement effect to the soil strength. (4) Without seismic acceleration and with no rainfall condition, it has Fs=1.75. These results can explain the real landslide occurrence in this area with the maximum seismic acceleration estimated as 0.15G in the vicinity of Kathmandu by the Gorkha Earthquake. Therefore, these results indicate landslide susceptibility of the slopes in this area with strong earthquake. In this situation, it is possible to predict

Epidemic meningococcal disease: recommendations for travelers to Nepal.

PubMed

1985-03-08

In the Kathmandu Valley of Nepal, an epidemic of serogroup A meningococcal meningitis resulted in 875 cases and 95 deaths during the 1st 6 months of 1983. The overall annual attack rate was 103 cases/100,000 population; the case fatality ratio was 11%. The highest age-specific attack rate (223/100,000) occurred among children under age 1 year. 3 times as many cases occurred in Kathmandu during December 1983 and January 1984 as in the same period a year previously. A mass vaccination campaign was initiated on February 8, 1984, and 330,000 doses of bivalent A/C meningococcal vaccine were administered, achieving approximately 65% coverage of the target population. A marked decline in the number of meningitis cases occurred coincident with the initiation of the mass campaign. In 1985 meningococcal meningitis is occurring at a much lower rate than in 1984, but meningococcal disease among hikers now is being recognized. Over the January 1984-January 1985 period, 2 culture-confirmed and 4 clinically suspected cases of meningococcal disease were documented among tourists from western countries traveling in Nepal. Patients ranged in age from 16-40 years. 5 patients had evidence of meningococcemia; the other had meningitis alone. 2 patients died, and all became ill during or shortly after hiking outside kathmandu. 3 patients were from the US, 2 from Australia, and 1 from Switzerland. Tables present data on cases of specified notifiable diseases in the US.

Scientific information on disasters such as earthquakes typically comes firstly from official organizations, news reports and interviews with experts, and later from scientific presentations and peer-reviewed articles. With the advent of the Internet and social media, this information is available in real-time from automated systems and within a dynamic, collaborative interaction between scientific experts, responders and the public. After the 2015 M7.8 Nepal earthquake, Twitter Tweets from earth scientists* included information, analysis, commentary and discussion on earthquake parameters (location, size, mechanism, rupture extent, high-frequency radiation, …), earthquake effects (distribution of felt shaking and damage, triggered seismicity, landslides, …), earthquake rumors (e.g. the imminence of a larger event) and other earthquake information and observations (aftershock forecasts, statistics and maps, source and regional tectonics, seismograms, GPS, InSAR, photos/videos, …).In the future (while taking into account security, false or erroneous information and identity verification), collaborative, real-time science on social media after a disaster will give earlier and better scientific understanding and dissemination of public information, and enable improved emergency response and disaster management.* A sample of scientific Tweets after the 2015 Nepal earthquake: In the first minutes: "mb5.9 Mwp7.4 earthquake Nepal 2015.04.25-06:11:25UTC", "Major earthquake shakes Nepal 8 min ago", "Epicenter between Pokhara and Kathmandu", "Major earthquake shakes Nepal 18 min ago.

Background A substantial proportion of the global burden of typhoid fever occurs in South Asia. Kathmandu, Nepal experienced a substantial increase in the number of typhoid fever cases (caused by Salmonella Typhi) between 2000 and 2003, which subsequently declined but to a higher endemic level than in 2000. This epidemic of S. Typhi coincided with an increase in organisms with reduced susceptibility against fluoroquinolones, the emergence of S. Typhi H58, and an increase in the migratory population in Kathmandu. Methods We devised a mathematical model to investigate the potential epidemic drivers of typhoid in Kathmandu and fit this model to weekly data of S. Typhi cases between April 1997 and June 2011 and the age distribution of S. Typhi cases. We used this model to determine if the typhoid epidemic in Kathmandu was driven by heightened migration, the emergence of organisms with reduced susceptibility against fluoroquinolones or a combination of these factors. Results Models allowing for the migration of susceptible individuals into Kathmandu alone or in combination with the emergence of S. Typhi with reduced susceptibility against fluoroquinolones provided a good fit for the data. The emergence of organisms with reduced susceptibility against fluoroquinolones organisms alone, either through an increase in disease duration or increased transmission, did not fully explain the pattern of S. Typhi infections. Conclusions Our analysis is consistent with the hypothesis that the increase in typhoid fever in Kathmandu was associated with the migration of susceptible individuals into the city and aided by the emergence of reduced susceptibility against fluoroquinolones. These data support identifying and targeting migrant populations with typhoid immunization programmes to prevent transmission and disease. PMID:28475605

This paper analyzes the climate change impact on water diversion plan of Melamchi Water Supply Project (MWSP) in Nepal. The MWSP is an interbasin water transfer project aimed at diverting water from the Melamchi River of the Indrawati River basin to Kathmandu Valley for drinking water purpose. Future temperature and precipitation of the basin were predicted using the outputs of two regional climate models (RCMs) and two general circulation models (GCMs) under two representative concentration pathway (RCP) scenarios which were then used as inputs to Soil and Water Assessment Tool (SWAT) to predict the water availability and evaluate the water diversion strategies in the future. The average temperature of the basin is projected to increase by 2.35 to 4.25 °C under RCP 4.5 and RCP 8.5, respectively, by 2085s. The average precipitation in the basin is projected to increase by 6-18 % in the future. The annual water availability is projected to increase in the future; however, the variability is observed in monthly water availability in the basin. The water supply and demand scenarios of Kathmandu Valley was also examined by considering the population increase, unaccounted for water and water diversion from MWSP in the future. It is observed that even with the additional supply of water from MWSP and reduction of unaccounted for water, the Kathmandu Valley will be still under water scarcity in the future. The findings of this study can be helpful to formulate water supply and demand management strategies in Kathmandu Valley in the context of climate change in the future.

Earth observation taken by the Expedition 25 crew

2010-11-09

ISS025-E-013115 (9 Nov. 2010) --- Kathmandu, Nepal is featured in this image photographed by an Expedition 25 crew member on the International Space Station. The capital and largest city of Nepal, Kathmandu occupies much of the Kathmandu Valley located near the center of the country. Nepal itself contains much of the Himalaya mountain range between China (Tibet) to the north and India to the south. Geological and fossil evidence indicates that the Kathmandu Valley was filled by a large lake (Paleo-Kathmandu Lake) between approximately 2.8 million and 10,000 years ago, according to scientists. Geologists believe the lake drained in phases over time due both to a drier regional climate, continuing tectonic uplift and faulting in the region, and formation of an integrated valley drainage system as river channels cut through previous natural rock ridge dams. The green vegetated slopes that ring the Kathmandu metro area (light gray, center) include both forest reserves and national parks. The metropolitan area is relatively flat compared to the surrounding high mountains. Tribhuvan International Airport, located near the current eastern margin of the metro area, is the only international airport in Nepal. Archeological evidence suggests that the development of Kathmandu, together with the nearby “sister cities” of Lalitpur and Bhaktapur, began almost 2,000 years ago. Today, Kathmandu and its sister cities form the governmental, cultural, and—as a main access point to the Himalayas for tourism—economic center of the country.

Background: Sterilization is most widely used fertility regulation method in Nepal. However, prevalence of uptake of female sterilization in central hilly region is less than the national average. The objective of the study was to explore the number and factors related to intention of married women to undergo female sterilization in rural Kathmandu which lies within central hilly region. Materials and Methods: This is a community based cross-sectional survey research conducted in rural area of Kathmandu valley. Two hundred and forty currently married women with at least one child of any age were interviewed using a structured pre-tested questionnaire. Results: More than four-fifth of the respondents intended to undergo sterilization. Almost two-third of them wanted to limit their family size by taking this option. More than one-third of women not-intending to undergo sterilization feared weakness after sterilization. Age of the respondents, duration of marriage, and number of living children were significantly associated with intention to undergo sterilization. 15-24 years age group were six times more likely to have the intention for sterilization (OR 6.79, CI 2.28-20.19) compared to age 35 years and above group. Mothers with less than 3 living children are about three times more likely to have the intention to undergo sterilization (OR 2.87, CI 1.3-6.33) compared to women with more than 2 living children. Women married for 6 to 10 years were three times more likely to have the intention (OR 3.0, CI 1.09-8.27). However, gender of the living children was not associated with intention to undergo sterilization. Conclusion: There were significant numbers of women intending to undergo sterilization. Age of the mother, number of living children and the duration of marriage were found to be significantly influencing the intention to undergo sterilization. However, as intention refers to future plan, the respondents’ intention may change over time. The national family

Abstract In order to assess the prevalence of point‐of‐sale promotions of infant and young child feeding products in Phnom Penh, Cambodia; Kathmandu Valley, Nepal; Dakar Department, Senegal; and Dar es Salaam, Tanzania, approximately 30 retail stores per site, 121 in total, were visited. Promotional activity for breastmilk substitutes (BMS) and commercially produced complementary foods in each site were recorded. Point‐of‐sale promotion of BMS occurred in approximately one‐third of sampled stores in Phnom Penh and Dakar Department but in 3.2% and 6.7% of stores in Kathmandu Valley and Dar es Salaam, respectively. Promotion of commercially produced complementary foods was highly prevalent in Dakar Department with half of stores having at least one promotion, while promotions for these products occurred in 10% or less of stores in the other three sites. While promotion of BMS in stores is legal in Senegal, it is prohibited in Cambodia without prior permission of the Ministry of Health/Ministry of Information and prohibited in both Nepal and Tanzania. Strengthening legislation in Senegal and enforcing regulations in Cambodia could help to prevent such promotion that can negatively affect breastfeeding practices. Key messages Even in countries such as Cambodia, Nepal and Tanzania where point‐of‐sale promotion is restricted, promotions of BMS were observed (in nearly one‐third of stores in Phnom Penh and less than 10% in Dar es Salaam and Kathmandu).Limited promotion of commercially produced complementary foods was evident (less than 10% of stores had a promotion for such foods), except in Dakar Department, where promotions were found in half of stores.Efforts are needed to strengthen monitoring, regulation and enforcement of restrictions on the promotion of BMS.Manufacturers and distributors should take responsibility for compliance with national regulations and global policies pertaining to the promotion of breastmilk substitutes.

To investigate the possible transmission of Blastocystis organisms between local rhesus monkeys and children in Kathmandu, Nepal, we compared the subtype (ST) and sequence of Blastocystis isolates from children with gastrointestinal symptoms and local rhesus monkeys. Twenty and 10 Blastocystis isolates were established from 82 and 10 fecal samples obtained from children and monkeys, respectively. Subtype analysis with seven sequence-tagged site (STS) primers indicated that the prevalence of Blastocystis sp. ST1, ST2 and ST3 was 20%, 20% and 60% in the child isolates, respectively. In contrast to human isolates, ST3 was not found in monkey isolates and the prevalence of ST1 and ST2 was 50% and 70%, respectively, including three mixed STs1 and 2 and one isolate not amplified by any STS primers, respectively. Since Blastocystis sp. ST2 has been reported as the most dominant genotype in the survey of Blastocystis infection among the various monkey species, sequence comparison of the 150bp variable region of the small subunit rRNA (SSU rRNA) gene was conducted among ST2 isolates of humans and monkeys. Sequence alignment of 24 clones developed from ST2 isolates of 4 humans and 4 monkeys showed three distinct subgroups, defined as ST2A, ST2B and ST2C. These three subgroups were shared between the child and monkey isolates. These results suggest that the local rhesus monkeys are a possible source of Blastocystis sp. ST2 infection of humans in Kathmandu.

Nepal is facing an increasing burden of diabetes and relies almost entirely on insulin imported through India. We employed a modified version of the WHO/Health Action International standard survey to assess insulin availability and prices, along with qualitative interviews with insulin retailers (pharmacists) and wholesalers in the Kathmandu Valley, Nepal. The mean availability of the two human insulins listed on the 2011 Nepal Essential Medicine List were 14.3% and 42.85% in the surveyed private- and public-sector pharmacies, respectively, compared with the WHO target of 80% availability. The median consumer price of human insulin cartridges, analogue insulin cartridges and pens was, respectively, 2.1, 4.6 and 5.3 times that of human insulin vials (US$5.54). The insulin cartridges made in India were less expensive (p<0.001) than those made elsewhere. The lowest-paid worker would need to spend between 3 and 17 days' wages to purchase a monthly insulin supply out of pocket. Insulin access is limited in Kathmandu owing to low availability and the highly unaffordable price. Insulin access could improve with the government exploring additional suppliers, pooling insulin tenders, auditing insulin utilization and developing independent prescribing guidelines. Furthermore, there is a need to educate physicians and develop a consensus statement on insulin initiation to curb the growing analogue use and promote rational use.

To determine the incidence of - and illnesses commonly associated with - catastrophic household expenditure on health in Nepal. We did a cross-sectional population-based survey in five municipalities of Kathmandu Valley between November 2011 and January 2012. For each household surveyed, out-of-pocket spending on health in the previous 30 days that exceeded 10% of the household's total expenditure over the same period was considered to be catastrophic. We estimated the incidence and intensity of catastrophic health expenditure. We identified the illnesses most commonly associated with such expenditure using a Poisson regression model and assessed the distribution of expenditure by economic quintile of households using the concentration index. Overall, 284 of the 1997 households studied in Kathmandu, i.e. 13.8% after adjustment by sampling weight, reported catastrophic health expenditure in the 30 days before the survey. After adjusting for confounders, this expenditure was found to be associated with injuries, particularly those resulting from road traffic accidents. Catastrophic expenditure by households in the poorest quintile were associated with at least one episode of diabetes, asthma or heart disease. In an urban area of Nepal, catastrophic household expenditure on health was mostly associated with injuries and noncommunicable diseases such as diabetes and asthma. Throughout Nepal, interventions for the control and management of noncommunicable diseases and the prevention of road traffic accidents should be promoted. A phased introduction of health insurance should also reduce the incidence of catastrophic household expenditure.

Like many national statistical surveys, the Agricultural Census of Nepal does not reflect the actual contribution of women's work in agriculture. Inadequacies in conceptualization, definition of terms and data gathering methods result in undervaluation and underrepresentation of women's work. This study of 124 Newar households in the Lubhu Village Development Committee, Kathmandu Valley, provides a statistical representation of women's roles in agricultural operations and household activities by assessing the actual extent of their work. After analyzing the gender division of labor, the study concludes that women's work in agriculture and household activities is significantly higher than men's work.

Detailed geodetic imaging of earthquake ruptures enhances our understanding of earthquake physics and associated ground shaking. The 25 April 2015 moment magnitude 7.8 earthquake in Gorkha, Nepal was the first large continental megathrust rupture to have occurred beneath a high-rate (5-hertz) Global Positioning System (GPS) network. We used GPS and interferometric synthetic aperture radar data to model the earthquake rupture as a slip pulse ~20 kilometers in width, ~6 seconds in duration, and with a peak sliding velocity of 1.1 meters per second, which propagated toward the Kathmandu basin at ~3.3 kilometers per second over ~140 kilometers. The smooth slip onset, indicating a large (~5-meter) slip-weakening distance, caused moderate ground shaking at high frequencies (>1 hertz; peak ground acceleration, ~16% of Earth’s gravity) and minimized damage to vernacular dwellings. Whole-basin resonance at a period of 4 to 5 seconds caused the collapse of tall structures, including cultural artifacts.

We present and describe strong-motion data observations from the 2015 M 7.8 Gorkha, Nepal, earthquake sequence collected using existing and new Quake-Catcher Network (QCN) and U.S. Geological Survey NetQuakes sensors located in the Kathmandu Valley. A comparison of QCN data with waveforms recorded by a conventional strong-motion (NetQuakes) instrument validates the QCN data. We present preliminary analysis of spectral accelerations, and peak ground acceleration and velocity for earthquakes up to M 7.3 from the QCN stations, as well as preliminary analysis of the mainshock recording from the NetQuakes station. We show that mainshock peak accelerations were lower than expected and conclude the Kathmandu Valley experienced a pervasively nonlinear response during the mainshock. Phase picks from the QCN and NetQuakes data are also used to improve aftershock locations. This study confirms the utility of QCN instruments to contribute to ground-motion investigations and aftershock response in regions where conventional instrumentation and open-access seismic data are limited. Initial pilot installations of QCN instruments in 2014 are now being expanded to create the Nepal–Shaking Hazard Assessment for Kathmandu and its Environment (N-SHAKE) network.

Diarrhoeal diseases are a major problem in developing countries. Though precise data on childhood mortality associated with diarrhoeal diseases in Nepal are not available, it has been estimated that approximately 25 % of child deaths are associated with diarrhoeal disease, particularly acute diarrhoea. The purpose of this study was to assess the incidence of rotavirus causing acute diarrhoea in children less than 5 years of age. A total of 525 children with acute diarrhoea in a children's hospital of Kathmandu, Nepal, were enrolled between April and September 2011. The incidence of acute diarrhoea due to rotavirus was 25.9 % (136/525) as determined by ELISA. The percentage of rotavirus-infected males was higher (64.5 %) than females (35.5 %). The frequency of rotavirus cases was higher in children less than 2 years of age, among which the majority of cases (80.2 %) were in children between 6 and 24 months old (P<0.01). Genotypic characterization by RT-PCR revealed that the serotype G12 represented 55.9 % of cases in this study associated with P-types of either P[6], P[4] or P[8]. Further to this, a total of eight G/P combinations were identified, G12P[6] being the most common strain type of rotavirus in Nepal, with a prevalence rate of 46.4 %. The aim of this study was to find out the major genotypes of rotavirus causing acute diarrhoea in children.

Introduction to the focus section on the 2015 Gorkha, Nepal, earthquake

It has long been recognized that Nepal faces high earthquake hazard, with the most recent large (Mw>7.5) events in 1833 and 1934. When the 25 April 2015Mw 7.8 Gorkha earthquake struck, it appeared initially to be a realization of worst fears. In spite of its large magnitude and proximity to the densely populated Kathmandu valley, however, the level of damage was lower than anticipated, with most vernacular structures within the valley experiencing little or no structural damage. Outside the valley, catastrophic damage did occur in some villages, associated with the high vulnerability of stone masonry construction and, in many cases, landsliding. The unexpected observations from this expected earthquake provide an urgent impetus to understand the event itself and to better characterize hazard from future large Himalayan earthquakes. Toward this end, articles in this special focus section present and describe available data sets and initial results that better illuminate and interpret the earthquake and its effects.

One of the UN sustainable development goals is to achieve universal access to safe and affordable drinking water by 2030. It is locations like Kathmandu, Nepal, a densely populated city in South Asia with endemic typhoid fever, where this goal is most pertinent. Aiming to understand the public health implications of water quality in Kathmandu we subjected weekly water samples from 10 sources for one year to a range of chemical and bacteriological analyses. We additionally aimed to detect the etiological agents of typhoid fever and longitudinally assess microbial diversity by 16S rRNA gene surveying. We found that the majority of water sources exhibited chemical and bacterial contamination exceeding WHO guidelines. Further analysis of the chemical and bacterial data indicated site-specific pollution, symptomatic of highly localized fecal contamination. Rainfall was found to be a key driver of this fecal contamination, correlating with nitrates and evidence of S. Typhi and S. Paratyphi A, for which DNA was detectable in 333 (77%) and 303 (70%) of 432 water samples, respectively. 16S rRNA gene surveying outlined a spectrum of fecal bacteria in the contaminated water, forming complex communities again displaying location-specific temporal signatures. Our data signify that the municipal water in Kathmandu is a predominant vehicle for the transmission of S. Typhi and S. Paratyphi A. This study represents the first extensive spatiotemporal investigation of water pollution in an endemic typhoid fever setting and implicates highly localized human waste as the major contributor to poor water quality in the Kathmandu Valley.

Geomorphic footprints of past large Himalayan earthquakes are elusive, although they are urgently needed for gauging and predicting recovery times of seismically perturbed mountain landscapes. We present evidence of catastrophic valley infill following at least three medieval earthquakes in the Nepal Himalaya. Radiocarbon dates from peat beds, plant macrofossils, and humic silts in fine-grained tributary sediments near Pokhara, Nepal's second-largest city, match the timing of nearby M > 8 earthquakes in ~1100, 1255, and 1344 C.E. The upstream dip of tributary valley fills and x-ray fluorescence spectrometry of their provenance rule out local sources. Instead, geomorphic and sedimentary evidence is consistent with catastrophic fluvial aggradation and debris flows that had plugged several tributaries with tens of meters of calcareous sediment from a Higher Himalayan source >60 kilometers away.

We assessed changes in HIV prevalence and risk behaviours among young key populations in Nepal. A total of 7505 participants (aged 16-24 years) from key populations who were at increased risk of HIV infection (2767 people who inject drugs (PWID); 852 men who have sex with men/transgender (MSM/TG); 2851 female sex workers (FSW) and 1035 male labour migrants) were recruited randomly over a 12-year period, 2001-2012. Local epidemic zones of Nepal (Kathmandu valley, Pokhara valley, Terai Highway and West to Far West hills) were analysed separately. We found a very strong and consistent decline in HIV prevalence over the past decade in different epidemic zones among PWID and MSM/TG in Kathmandu, the capital city, most likely due to a parallel increase in safe needle and syringe use and increased condom use. A decrease in HIV prevalence in 22 Terai highway districts, sharing an open border with India, was also consistent with increased condom use among FSW. Among male labour migrants, HIV prevalence was low throughout the period in the West to Far West hilly regions. Condom use by migrant workers involved with FSW abroad increased while their condom use with Nepalese FSW declined. Other risk determinants such as mean age at starting first injection, injection frequency, place of commercial sex solicitation, their mean age when leaving to work abroad did not change consistently across epidemic zones among the young key populations under study. In Nepal, the decline in HIV prevalence over the past decade was remarkably significant and consistent with an increase in condom use and safer use of clean needles and syringes. However, diverging trends in risk behaviours across local epidemic zones of Nepal suggest a varying degree of implementation of national HIV prevention policies. This calls for continued preventive efforts as well as surveillance to sustain the observed downward trend.

Detailed geodetic imaging of earthquake rupture enhances our understanding of earthquake physics and induced ground shaking. The April 25, 2015 Mw 7.8 Gorkha, Nepal earthquake is the first example of a large continental megathrust rupture beneath a high-rate (5 Hz) GPS network. We use GPS and InSAR data to model the earthquake rupture as a slip pulse of ~20 km width, ~6 s duration, and with peak sliding velocity of 1.1 m/s that propagated toward Kathmandu basin at ~3.3 km/s over ~140 km. The smooth slip onset, indicating a large ~5 m slip-weakening distance, caused moderate ground shaking at high >1Hz frequencies (~16% g) and limited damage to regular dwellings. Whole basin resonance at 4-5 s period caused collapse of tall structures, including cultural artifacts.

In Nepal, burn trauma causes more than 55,000 injuries each year. Burn-related mortality is high in Nepal, in part due to lack of allograft, leading to high infection rates. To address this challenge, our collaboration between Kirtipur Hospital, America Nepal Medical Foundation, Stanford University, and ReSurge International established Nepal's first skin bank. We identified 3 major tasks to create a sustainable skin banking program: 1) identify and acquire the equipment and personnel needed to collect, process, store, and graft cadaveric skin for burn injuries; 2) develop safe donation protocols and documentation tools that remain feasible for low-resource settings; and 3) develop a long-term awareness program to educate the Nepali people on skin donation, a previously foreign concept. Kirtipur Hospital acquired the necessary equipment and materials for the skin bank through a combination of local and international fundraising efforts. Existing U.S. skin banking protocols were adapted for the Nepali setting and piloted on potential patients, donors, and physicians. For the first time in the hospital's history, patients with > 40% total body surface area burns were successfully treated with extensive allografts. It is feasible to create a skin bank in a country with no tradition of allograft skin use. Long-term sustainability now depends on spreading awareness and education in the Kathmandu Valley to overcome religious and cultural barriers that have hindered donor recruitment. Our low-cost and high-impact skin bank provides a model to expand this system to other hospitals both within Nepal and beyond.

In 2002 MTV aired a global media campaign, "Staying Alive," to promote HIV prevention among 16- to 25-year-olds. Skeptics believed that a global MTV campaign would reach only a small group of elite young people. MTV increased access to its campaign, however, by making all materials "rights free" to third-party (non-MTV) broadcasters. Over 789 million households in over 166 countries had access to some or all of the campaign. To understand the level of actual exposure and the types of young people exposed, data were analyzed from population-based household surveys in three diverse urban areas where a campaign evaluation was conducted: Kathmandu, Nepal; São Paulo, Brazil and Dakar, Senegal. Exposure rates ranged from 12% in Kathmandu, 23% in São Paulo, and 82% in Dakar, reaching an estimated 32,000, 400,000, 220,000 16- to 25-year-olds in each city, respectively. A number of personal, social and economic characteristics found to predict campaign exposure were identified in each site; in general, these were related to economic status and use of "new" media technologies. Though this skew toward more exposure by those with greater resources existed, we found that the campaign audience was in no way composed only of "elite" young people. (For example, although more of those exposed to the campaign had used the Internet compared with those not exposed, this was not the majority of those exposed in most countries.) The possibility of reaching millions of young people through global networks with minimal marginal costs after production, creates a new paradigm for reaching an important segment of young people.

We have recently resurrected the name Entamoeba nuttalli Castellani, 1908 for a potentially virulent ameba isolate, P19-061405, obtained from a rhesus macaque in Kathmandu, Nepal. The ameba was morphologically indistinguishable from Entamoeba histolytica/Entamoeba dispar/Entamoeba moshkovskii, but located phylogenetically between E. histolytica and E. dispar. To evaluate the prevalence of E. nuttalli infection in wild rhesus macaques, 112 fecal samples were collected in four locations of the Kathmandu Valley. PCR analysis of DNA extracted from the feces showed positive rates of E. nuttalli, E. dispar, E. histolytica and E. moshkovskii of 51%, 12%, 0% and 0%, respectively. A total of 14 E. nuttalli isolates were obtained from four locations, of which 6 were established as axenic cultures. The sequences of the serine-rich protein gene of E. nuttalli isolates differed among four locations although no differences were found in the composition of sequence motifs. Isoenzyme pattern was analyzed in 8 isolates obtained from three locations. In hexokinase, the mobility of the slower migrating band was located between E. histolytica and E. dispar regardless of the culture conditions. These results demonstrate that E. nuttalli is highly prevalent in wild rhesus macaques in Nepal. Rhesus macaques appear to be one of the natural hosts and heterogeneity of the serine-rich protein gene might be useful for geographical typing of isolates. Copyright © 2013 Elsevier Ireland Ltd.

Strong ground motions from the 2015 Mw 7.8 Gorkha, Nepal, earthquake and its eight aftershocks recorded by a strong-motion seismograph at Kantipath (KATNP), Kathmandu, were analyzed to assess the ground-motion characteristics and site effects at this location. Remarkably large elastic pseudo-velocity responses exceeding 300 cm/s at 5 % critical damping were calculated for the horizontal components of the mainshock recordings at peak periods of 4-5 s. Conversely, the short-period ground motions of the mainshock were relatively weak despite the proximity of the site to the source fault. The horizontal components of all large-magnitude (Mw ≥ 6.3) aftershock recordings showed peak pseudo-velocity responses at periods of 3-4 s. Ground-motion prediction equations (GMPEs) describing the Nepal Himalaya region have not yet been developed. A comparison of the observational data with GMPEs for Japan showed that with the exception of the peak ground acceleration (PGA) of the mainshock, the observed PGAs and peak ground velocities at the KATNP site are generally well described by the GMPEs for crustal and plate interface events. A comparison of the horizontal-to-vertical ( H/ V) spectral ratios for the S-waves of the mainshock and aftershock recordings suggested that the KATNP site experienced a considerable nonlinear site response, which resulted in the reduced amplitudes of short-period ground motions. The GMPEs were found to underestimate the response values at the peak periods (approximately 4-5 s) of the large-magnitude events. The deep subsurface velocity model of the Kathmandu basin has not been well investigated. Therefore, a one-dimensional velocity model was constructed for the deep sediments beneath the recording station based on an analysis of the H/ V spectral ratios for S-wave coda from aftershock recordings, and it was revealed that the basin sediments strongly amplified the long-period components of the ground motions of the mainshock and large

Youth have the right to utilise sexual and reproductive health (SRH) services and information to protect themselves from negative SRH outcomes. This study aimed to assess knowledge, experience and use of SRH services amongst youth living in urban areas of the Kathmandu Valley. We conducted a two stage cluster sampling cross-sectional household survey of young men and women aged 15-24 living in the Kathmandu Valley using a structured questionnaire. Amongst the 680 young men and 720 young women participants, less than two-thirds had knowledge about the fertile period and less than a half about pregnancy risk at first sex. Over three quarters of young men and women had knowledge of condoms, and pills but less than half knew about implants or intrauterine devices. Age at first sex was similar for men and women but women were significantly less likely to have participated willingly in their first sexual encounter and were less likely to have used any contraception (for both p < 0.001). Almost all men and women (97.9%) had heard of sexually transmitted infections (STIs) but only 8% had heard about the most common STI, Chlamydia. Over 90% of youth reported feelings of shame as the major barrier to accessing SRH services. Gaps exist between youth SRH knowledge and practices which leave them vulnerable to sexual ill health. This may indicate a lack of confidence in SRH services but also likely reflects the cultural and religious environment that hampers open expression of sexual and reproductive issues, particularly for young women.

Staphylococcus aureus, an important nosocomial pathogen, is frequently associated with infections in human. The management of the infections by it especially methicillin resistant ones is often difficult because methicillin resistant S. aureus is usually resistant to multiple antibiotics. Macrolide-lincosamide streptogramin B family of antibiotics is commonly used to treat such infections as an alternative to vancomycin. This study was conducted over the period of one and half year from November 2013-April 2015 in Microbiology laboratory of Nepal Medical College and Teaching Hospital, Kathmandu, Nepal to find the incidence of different phenotypes of MLS B resistance among S. aureus from clinical samples and their association with methicillin resistance. Two hundred seventy isolates of S. aureus were included in the study. Methicillin resistance was detected by cefoxitin disc diffusion method and inducible clindamycin resistance by erythromycin and clindamycin disc approximation test (D-test). Of the 270 clinical isolates of S. aureus, 25.1% (68/270) were MRSA. Erythromycin and clindamycin resistance was seen in 54.4% (147/270) and 41.8% (113/270) isolates respectively. Resistance to erythromycin and clindamycin were higher in MRSA as compared to MSSA (erythromycin-resistance: 88.2% Vs 39.1% and clindamycin-resistance: 79.4% Vs 41.8%). The overall prevalence of i MLS B and c MLS B phenotype was 11.48% (31/270) and 29.25% (79/270) respectively. Both i MLS B and c MLS B phenotypes predominated in MRSA strains. Detection rate of MRSA in our study shows the necessity to improve in healthcare practices and to formulate new policy for the control of MRSA infections. Clindamycin resistance in the form of i MLS B and c MLS B especially among MRSA emphasizes the need of D-test to be performed routinely in our set up while using clindamycin as an alternative choice to anti-staphylococcal antibiotics like vancomycin and linezolid in the treatment of staphylococcal infections.

Haemophilus influenzae type b (Hib) is a major cause of invasive bacterial infection in children that can be prevented by a vaccine, but there is still uncertainty about its relative importance in Asia. This study investigated the age-specific prevalence of Hib carriage and its molecular epidemiology in carriage and disease in Nepal. Oropharyngeal swabs were collected from children in Kathmandu, Nepal, from 3 different settings: a hospital outpatient department (OPD), schools, and children's homes. Hib was isolated using Hib antiserum agar plates, and serotyping was performed with latex agglutination. Hib isolates from children with invasive disease were obtained during active microbiological surveillance at Patan Hospital, Kathmandu, Nepal. Genotyping of disease and carriage isolates was undertaken using multilocus sequence typing (MLST). Swabs were taken from 2,195 children, including 1,311 children at an OPD, 647 children attending schools, and 237 children in homes. Overall, Hib was identified in 5.0% (110/2,195; 95% confidence interval [95% CI], 3.9% to 6.4%). MLST was performed on 108 Hib isolates from children carrying Hib isolates and 15 isolates from children with invasive disease. Thirty-one sequence types (STs) were identified, and 20 of these were novel STs. The most common ST isolates were sequence type 6 (ST6) and the novel ST722. There was marked heterogeneity among the STs from children with disease and children carrying Hib. STs identified from invasive infections were those commonly identified in carriage. This study provides evidence of Hib carriage among children in urban Nepal with genetically diverse strains prior to introduction of universal vaccination. The Hib carriage rate in Nepal was similar to the rates observed in other populations with documented high disease rates prior to vaccination, supporting implementation of Hib vaccine in Nepal in 2009.

SIT Study Abroad (School of International Training), in collaboration with Nepal's national university - Tribhuvan University, runs a seven-week summer field education called "Nepal: Geoscience in the Himalaya". The program is designed to teach core geoscience field skills as well as geohazard analysis and intercultural science collaboration. Approximately 70% of the students come from colleges across the USA and 30% come from Tribhuvan University. A key element of the learning is how to work effectively with colleagues from a different educational system and culture. The program starts with a four-day orientation in Kathmandu and then travels to the Kali Gandaki Valley of western Nepal. Everyone treks on foot while completing a geologic transect map from south to north across the main Himalayan range. More traditional field skills are learned during a detailed stratigraphic exercise. On the way back down the valley, the emphasis changes to surface processes and students complete an air photo analysis and small research project on human-earth system interactions. Once back on the road system, the students conduct both a landslide hazard analyses and an earthquake damage assessment. Throughout this time, students maintain a research ideas journal from which they develop an independent study project, which they carry out during the last two weeks of the program. The program particularly emphasizes affordable, sustainable solutions to geohazards that are appropriate for a developing country such as Nepal—a very eye-opening approach for students from the USA. The overall program mission is to promote geoscience field skill development in a societal context and more globally informed scientists, citizens, and leaders.

The costs of delay in infrastructure investments: A comparison of 2001 and 2014 household water supply coping costs in the Kathmandu Valley, Nepal

In 2001, we conducted a survey of 1500 randomly sampled households in Kathmandu to determine the costs people were incurring to cope with Kathmandu's poor quality, unreliable piped water supply system. From 2001 until 2014, there was little additional public investment in the municipal water supply system. In the summer of 2014, we attempted to reinterview all 1500 households in our 2001 sample to determine how they had managed to deal with the growing water shortage and the deteriorating condition of the piped water infrastructure in Kathmandu and to compare their coping costs in 2014 with those we first estimated in 2001. Average household coping costs more than doubled in real terms over the period from 2001 to 2014, from US5 to US12 per month (measured in 2014 prices). The composition of household coping costs changed from 2001 to 2014, as households responded to the deteriorating condition of the piped water infrastructure by drilling more private wells, purchasing water from both tanker truck and bottled water vendors, and installing more storage tanks. These investments and expenditures resulted in a decline in the time households spend collecting water from outside the home. Our analysis suggests that the significant increase in coping costs between 2001 and 2014 may provide an opportunity for the municipal water utility to substantially increase water tariffs if the quantity and quality of piped services can be improved. However, the capital investments made by some households in private wells, pumping and treatment systems, and storage tanks in response to the delay in infrastructure investment may lock them into current patterns of water use, at least in the short run, and thus make it difficult to predict how they would respond to tariff increases for improved piped water services.

Multicenter surveillance has been carried out on maternal near-miss in the hospitals with sentinel units. Near-miss is recognized as the predictor of level of care and maternal death. Reducing Maternal Mortality Ratio is one of the challenges to achieve Millennium Development Goal. The objective was to determine the frequency and the nature of near-miss events and to analyze the near-miss morbidities among pregnant women. A prospective surveillance was done for a year in 2012 at nine hospitals in Kathmandu valley. Cases eligible by definition were recorded as a census based on WHO near-miss guideline. Similar questionnaires and dummy tables were used to present the results by non-inferential statistics. Out of 157 cases identified with near-miss rate of 3.8 per 1000 live births, severe complications were postpartum hemorrhage 62 (40%) and preeclampsia-eclampsia 25 (17%). Blood transfusion 102 (65%), ICU admission 85 (54%) and surgery 53 (32%) were common critical interventions. Oxytocin was main uterotonic used both prophylactically and therapeutically at health facilities. Total of 30 (19%) cases arrived at health facility after delivery or abortion. MgSO4 was used in all cases of eclampsia. All laparotomies were performed within three hours of arrival. Near-miss to maternal death ratio was 6:1 and MMR was 62. Study result yielded similar pattern amongst developing countries and same near-miss conditions as the causes of maternal death reported by national statistics. Process indicators qualified the recommended standard of care. The near-miss event could be used as a surrogate marker of maternal death and a window for system level intervention.

The foreland fold and thrust belt in the Nepal Himalaya has developed over the last 2 My (Mugnier et al., 2004; Van der Beek et al., 2006), and is generally referred to as the Main Frontal Thrust system (MFT; Gansser, 1964). The thrust faults there are spaced 5-30 km apart. Where the faults are furthest from each other, they create piggy-back basins, known as "dun" valleys in the Himalaya. The easternmost of these basins in Nepal is the Triyuga river valley, a 35 km wide basin where the range front abruptly steps 15 km to the south. This dun valley is thought to be the youngest of Nepal, initiating in the Late Pleistocene (Kimura, 1999). In order to understand the sub-surface structure and development of the Triyuga Valley, we analyse high resolution seismic reflection profiles across the three basin-surrounding structures, as well as a north-south profile across the basin proper, in combination with field observations. These datasets reveal that the edges of the forward step are defined by three orthogonal thrust fronts, with abrupt changes in vergence direction. Sharp geometric changes along the range front may have implications for the propagation of earthquakes along the MFT. The surface rupture of the Nepal-Bihar 1934 earthquake was inferred to go around this thrust front (Sapkota et al., 2013), however field observations suggest that although past earthquakes have likely ruptured the surface here, these faults did not slip in 1934. Further, analogue models suggest that the filling of the basin with sediments may affect the activation of out of sequence thrusts (Toscani et al., 2014). This is consistent with field evidence of Quaternary reactivation of the Main Boundary Thrust north of the Triyuga Valley. We also compare these seismic profiles to one across the Jalthal anticline, an incipient structure forming 50 km south of the range front in easternmost Nepal (a section thought to have ruptured in 125; Nakata et al., 1998). We suggest that this may be an

To better quantify the relatively long period (< 0.3 Hz) shaking experienced during the 2015 Gorkha (Nepal) earthquake sequence, we study the finite rupture processes and the associated 3D ground motion of the Mw7.8 mainshock and the Mw7.2 aftershock. The 3D synthetics are then used in the broadband ground shaking in Kathmandu with a hybrid approach, summarized in a companion paper (Chen and Wei, 2017, submitted together). We determined the coseismic rupture process of the mainshock by joint inversion of InSAR/SAR, GPS (static and high-rate), strong motion and teleseismic waveforms. Our inversion for the mainshock indicates unilateral rupture towards the ESE, with an average rupture speed of 3.0 km/s and a total duration of 60 s. Additionally, we find that the beginning part of the rupture (5-18 s) has about 40% longer rise time than the rest of the rupture, as well as slower rupture velocity. Our model shows two strong asperities occurring 24 s and 36 s after the origin and located 30 km to the northwest and northeast of the Kathmandu valley, respectively. In contrast, the Mw7.2 aftershock is more compact both in time and space, as revealed by joint inversion of teleseismic body waves and InSAR data. The different rupture features between the mainshock and the aftershock could be related to difference in fault zone structure. The mainshock and aftershock ground motions in the Kathmandu valley, recorded by both strong motion and high-rate GPS stations, exhibited strong amplification around 0.2 Hz. A simplified 3D basin model, calibrated by an Mw5.2 aftershock, can match the observed waveforms reasonably well at 0.3 Hz and lower frequency. The 3D simulations indicate that the basin structure trapped the wavefield and produced an extensive ground vibration. Our study suggests that the combination of rupture characteristics and propagational complexity are required to understand the ground shaking produced by hazardous earthquakes such as the Gorkha event.

The need for a national urbanization policy in Nepal.

There is a need for a national urbanization policy in Nepal as a means of redressing regional disparities in development between the hills, the Kathmandu Valley, and the Terai versus rural and urban areas. A settlement system would complement urban and rural development and reduce dependency on India. An urbanization policy would be both systematic and guided by public and private investment in existing urban and rural settlements. Regional investment in development would contribute to commercialization and agricultural industrialization (development and linkage of market towns and service centers, strengthening of basic infrastructure and land use patterns, strengthening of urban areas around transportation centers, promoting nonfarm employment opportunities, establishing strong financial and technical institutions in middle-sized cities, and strengthening municipalities' mobilization of local resources and financing). Nepal has been one of the least developed countries in its region. The agricultural economy provides economic support for 80% of total population. In 1991, density was 130 person per sq. km. 9% of the total population live in urban areas, but the rate of urban growth is the highest among South Asian Regional Cooperation countries (7.3% in Nepal compared to 6.1% in Bangladesh and 3.7% in India). Rural markets and towns are rapidly becoming urbanized but without basic infrastructure. The spatial component of urbanization must be emphasized. Total population increased in the Terai from 37% in 1971 to 47% in 1991, which increased population density by 31% but not cultivation. Harsh physical conditions in mountainous regions and lack of cultivable land are push factors. Pull factors are employment opportunities in emerging urban centers and the availability of agricultural employment in the Terai. Movement to lowlands is enhanced by the eradication of malaria. 53% of the urban population is in the Terai in 1991, which also has 65% of cultivable land, 35

Vacant hospitals and under-employed nurses: a qualitative study of the nursing workforce management situation in Nepal.

PubMed

Adhikari, Radha

2015-04-01

It is vital for all healthcare systems to have a sufficient number of suitably trained health professionals including nurses at all levels of health services to deliver effective healthcare. An ethnographic, qualitative method was chosen for this study, which included open-ended, in-depth interviews with a range of stakeholders including student nurses, qualified nurses, nurse managers and lecturers, and the human resource co-ordinator in the Ministry of Health and Population. Available records and policy documents were also analysed. Study findings suggest that there is a severe mal-distribution of the nursing workforce in rural and urban healthcare centres in Nepal. Although there is an oversupply of newly qualified nurses in hospitals in Kathmandu, the staffing situation outside the valley is undesirable. Additionally, the turnover of junior nursing staff remains high in major urban hospitals. Most qualified nurses aspire to work in developed countries, such as the UK, North America, Australia and New Zealand. Between 2000 and 2008, as many as 3000 nurses have left Nepal for jobs in the developed west. There is no effective management strategy in place to retain a nursing workforce, particularly in rural Nepal. This article concludes by proposing some suggestions for a nursing workforce retention policy to address this critical issue.

Previous studies reported that the 2015 Gorkha earthquake (Mw 7.8), which occurred in Nepal, triggered landslides in mountainous areas. In Kathmandu, earthquake-induced land subsidence was identified by interpreting local phase changes in interferograms produced from Advanced Land Observing Satellite-2/Phased Array type L-band Synthetic Aperture Radar-2 data. However, the associated ground deformation was not discussed in detail. We studied line-of-sight (LoS) changes from InSAR images in the SE area of Tribhuvan International Airport, Kathmandu. To obtain the change in LoS caused only by local, short-wavelength surface deformation, we subtracted the change in LoS attributed to coseismic deformation from the original change in LoS. The resulting change in LoS showed that the river terrace was driven to the bottom of the river valley. We also studied the changes in LoS in both ascending and descending InSAR images of the area along the Bishnumati River and performed 2.5D analysis. Removing the effect of coseismic deformation revealed east-west and up-down components of local surface deformation, indicating that the river terrace deformed eastward and subsided on the western riverbank of the river. On the east riverbank, the river terrace deformed westward and subsided. However, in the southern part of the river basin, the river terrace deformed westward and was uplifted. The deformation data and field survey results indicate that local surface deformation in these two areas was not caused by land subsidence but by a landslide (specifically, lateral spread).

Large Himalayan earthquakes expose rapidly growing populations of millions of people to high levels of seismic hazards, in particular in northeast India and Nepal. Calibrating vulnerability models specific to this region of the world is therefore crucial to the development of reliable mitigation measures. Here, we reevaluate the >15,700 casualties (8500 in Nepal and 7200 in India) from the M w ~8.2, 1934, Bihar-Nepal earthquake and calculate the fatality rates for this earthquake using an estimation of the population derived from two census held in 1921 and 1942. Values reach 0.7-1 % in the epicentral region, located in eastern Nepal, and 2-5 % in the urban areas of the Kathmandu valley. Assuming a constant vulnerability, we obtain, if the same earthquake would have repeated in 2011, fatalities of 33,000 in Nepal and 50,000 in India. Fast-growing population in India indeed must unavoidably lead to increased levels of casualty compared with Nepal, where the population growth is smaller. Aside from that probably robust fact, extrapolations have to be taken with great caution. Among other effects, building and life vulnerability could depend on population concentration and evolution of construction methods. Indeed, fatalities of the April 25, 2015, M w 7.8 Gorkha earthquake indicated on average a reduction in building vulnerability in urban areas, while rural areas remained highly vulnerable. While effective scaling laws, function of the building stock, seem to describe these differences adequately, vulnerability in the case of an M w >8.2 earthquake remains largely unknown. Further research should be carried out urgently so that better prevention strategies can be implemented and building codes reevaluated on, adequately combining detailed ancient and modern data.

Transport of regional pollutants through a remote trans-Himalayan valley in Nepal

Anthropogenic emissions from the combustion of fossil fuels and biomass in Asia have increased in recent years. High concentrations of reactive trace gases and light-absorbing and light-scattering particles from these sources form persistent haze layers, also known as atmospheric brown clouds, over the Indo-Gangetic plains (IGP) from December through early June. Models and satellite imagery suggest that strong wind systems within deep Himalayan valleys are major pathways by which pollutants from the IGP are transported to the higher Himalaya. However, observational evidence of the transport of polluted air masses through Himalayan valleys has been lacking to date. To evaluate this pathway, we measured black carbon (BC), ozone (O3), and associated meteorological conditions within the Kali Gandaki Valley (KGV), Nepal, from January 2013 to July 2015. BC and O3 varied over both diurnal and seasonal cycles. Relative to nighttime, mean BC and O3 concentrations within the valley were higher during daytime when the up-valley flow (average velocity of 17 m s-1) dominated. BC and O3 concentrations also varied seasonally with minima during the monsoon season (July to September). Concentrations of both species subsequently increased post-monsoon and peaked during March to May. Average concentrations for O3 during the seasonally representative months of April, August, and November were 41.7, 24.5, and 29.4 ppbv, respectively, while the corresponding BC concentrations were 1.17, 0.24, and 1.01 µg m-3, respectively. Up-valley fluxes of BC were significantly greater than down-valley fluxes during all seasons. In addition, frequent episodes of BC concentrations 2-3 times higher than average persisted from several days to a week during non-monsoon months. Our observations of increases in BC concentration and fluxes in the valley, particularly during pre-monsoon, provide evidence that trans-Himalayan valleys are important conduits for transport of pollutants from the IGP to the

The availability and consumption of commercially produced foods and beverages have increased across low-income and middle-income countries. This cross-sectional survey assessed consumption of commercially produced foods and beverages among children 6-23 months of age, and mothers' exposure to promotions for these products. Health facility-based interviews were conducted among 218 randomly sampled mothers utilizing child health services in Dakar, Senegal; 229 in Dar es Salaam, Tanzania; 228 in Kathmandu Valley, Nepal; and 222 in Phnom Penh, Cambodia. In the day prior to the interview, 58.7% of 6-23-month-olds in Dakar, 23.1% in Dar es Salaam, 74.1% in Kathmandu Valley, and 55.0% in Phnom Penh had consumed a commercially produced snack food. In the previous week, the majority of children in Dakar (79.8%), Kathmandu Valley (91.2%), and Phnom Penh (80.6%) had consumed such products. Consumption of commercially produced sugar-sweetened beverages was noted among 32.0% of Phnom Penh, 29.8% of Dakar, 23.1% of Dar es Salaam, and 16.2% of Kathmandu Valley children. Maternal education was negatively associated with commercial snack food consumption in Dakar and Kathmandu Valley. Children of Phnom Penh mothers in the lowest wealth tercile were 1.5 times more likely to consume commercial snack food products, compared to wealthier mothers. These snack consumption patterns during the critical complementary feeding period demand attention; such products are often high in added sugars and salt, making them inappropriate for infants and young children. © 2017 John Wiley & Sons Ltd.

Social determinants that lead to poor knowledge about, and inappropriate precautionary practices towards, avian influenza among butchers in Kathmandu, Nepal

2013-01-01

Background Avian influenza (AI) is a global public health threat. Understanding the knowledge that butchers have about it and the precautionary practices they take against it is crucial for designing future preparedness programs. This study aimed to identify the social determinants of knowledge and precautionary measures of AI among butchers in the Kathmandu district in Nepal. Methods The study was based on a cross-sectional study design using structured interview questionnaires and checklists to observe social determinants and the precautionary measures of 120 butchers aged 15 years and above from the Kathmandu district. Results The majority of the respondents were male (69.2%) and more than half (53.3%) were from the age group of 25–39 years (mean: 31.08, SD: ±9.82). Nearly two-thirds (61.3%) of the respondents had a ‘poor knowledge’, and the remaining had ‘some knowledge’, about AI. More than half (55.4%) of the respondents were in the category of displaying ‘poor practice’ towards AI and the remaining half were in the ‘satisfactory practice’ category. None of the respondents had ‘adequate knowledge’ or displayed ‘good practice’. The respondents in the >25 years of age group were less likely [OR 0.169; 95% CI (0.056-0.512)] compared to those in the <25 years age group to have a poor knowledge about AI; and the respondents with ‘primary education’ were more likely [OR 3.265; 95% CI (1.326-8.189)] to have a poor knowledge about AI as compared to those who had a secondary or above level of education. Respondents who did not know the correct definition of AI were more likely to follow poor practices [OR 4.265; 95% CI (1.193-15.242)]; and the respondents who did not know the risk groups associated with AI were also more likely to follow poor practices [OR 3.103; 95% CI (1.191-8.083)]. Conclusion This study points out the need to address butchers to improve their knowledge of, and more importantly their compliance with, the precautionary

Nepal was struck by a massive earthquake on the 25th April 2015 and major aftershock on the 12th of May 2015, resulting in widespread devastation with a death toll in the thousands. The burden of ocular trauma resulting from the recent earthquakes in Nepal has not been described thus far. The aim of this study was to determine the types of ocular injuries sustained in the earthquake in Nepal and its management in Tilganga Institute of Ophthalmology (TIO) in Gaushala, Kathmandu. This is a hospital-based retrospective study of patients presenting to TIO following repeated earthquake. Variables that were recorded included patients' presenting symptoms and time to presentation, visual acuities at presentation and at follow-up, diagnosis of ocular injury and surgery performed. There were 59 cases of earthquake victims visiting TIO, Gaushala, Kathmandu from April 2015 to July 2015, with 64 affected eyes due to 5 cases of bilateral involvement. The majority of patients were from the district Sindhupalchowk (14 cases, 23.7%), which was the epicenter of the main earthquake. The average duration between the earthquake and presentation was 13 · 9 days (range 1-120 days). Closed globe injury was most frequent (23 cases), followed by open globe injuries (8 cases). While 24 patients (38%) initially presented with a visual acuity <3/60 in their affected eye, 15 patients (23%) had a visual acuity of <3/60 on follow-up. A variety of surgical treatments were required including anterior and posterior segment repair. Immediate management of ocular trauma is critical in order to prevent blindness. Characterizing the burden of earthquake-related ocular trauma will facilitate planning for service provision in the event of a future earthquake in Nepal, or in countries, which are similarly at risk of having natural disasters.

Uncertain timing and magnitudes of past mega-earthquakes continue to confound seismic risk appraisals in the Himalayas. Telltale traces of surface ruptures are rare, while fault trenches document several events at best, so that additional proxies of strong ground motion are needed to complement the paleoseismological record. We study Nepal's Pokhara basin, which has the largest and most extensively dated archive of earthquake-triggered valley fills in the Himalayas. These sediments form a 148-km2 fan that issues from the steep Seti Khola gorge in the Annapurna Massif, invading and plugging 15 tributary valleys with tens of meters of debris, and impounding several lakes. Nearly a dozen new radiocarbon ages corroborate at least three episodes of catastrophic sedimentation on the fan between ∼700 and ∼1700 AD, coinciding with great earthquakes in ∼1100, 1255, and 1344 AD, and emplacing roughly >5 km3 of debris that forms the Pokhara Formation. We offer a first systematic sedimentological study of this formation, revealing four lithofacies characterized by thick sequences of mid-fan fluvial conglomerates, debris-flow beds, and fan-marginal slackwater deposits. New geochemical provenance analyses reveal that these upstream dipping deposits of Higher Himalayan origin contain lenses of locally derived river clasts that mark time gaps between at least three major sediment pulses that buried different parts of the fan. The spatial pattern of 14C dates across the fan and the provenance data are key to distinguishing these individual sediment pulses, as these are not evident from their sedimentology alone. Our study demonstrates how geomorphic and sedimentary evidence of catastrophic valley infill can help to independently verify and augment paleoseismological fault-trench records of great Himalayan earthquakes, while offering unparalleled insights into their long-term geomorphic impacts on major drainage basins.

To describe the pattern of hypothermia and cold stress after delivery among a normal neonatal population in Nepal; to provide practical advice for improving thermal care in a resource limited maternity hospital. The principal government funded maternity hospital in Kathmandu, Nepal, with an annual delivery rate of 15,000 (constituting 40% of all Kathmandu Valley deliveries), severe resource limitations (annual budget Pounds 250,000), and a cold winter climate provided the setting. Thirty five healthy term neonates not requiring special care were enrolled for study within 90 minutes of birth. Continuous ambulatory temperature monitoring, using microthermistor skin probes for forehead and axilla, a flexible rectal probe, and a black ball probe placed next to the infant for ambient temperature, was carried out. All probes were connected to a compact battery powered Squirrel Memory Logger, giving a temperature reading to 0.2 degree C at five minute intervals for 24 hours. Severity and duration of hypothermia, using cutoff values of core temperature less than 36 degrees C, 34 degrees C, and 32 degrees C; and cold stress, using cutoff values of skin-core (forehead-axilla) temperature difference greater than 3 degrees C and 4 degrees C were the main outcome measures. Twenty four hour mean ambient temperatures were generally lower than the WHO recommended level of 25 degrees C (median 22.3 degrees C, range 15.1-27.5 degrees C). Postnatal hypothermia was prolonged, with axillary core temperatures only reaching 36 degrees C after a mean of 6.4 hours (range 0-21.1; SD 4.6). There was persistent and increasing cold stress over the first 24 hours with the core-skin (axillary-forehead) temperature gap exceeding 3 degrees C for more than half of the first 24 hours. Continuous ambulatory recording identifies weak links in the "warm chain" for neonates. The severity and duration of thermal problems was greater than expected even in a hospital setting where some of the WHO

Human resource data is essential for planning and implementation of health care delivery system. However, very few information is available on dental health human resource in the country. The aim of study was to assess the number of dentists in the country and to explore their distribution according to demographic and professional characteristics. A census was performed during July 2015 to July 2016 about the Nepali dentists. The study assessed demographic and professional characteristics of dentists including age, gender, ethnicity, education attainment, university, country/year of graduation, and work place using data collection sheet by trained data collectors. For those not accessible for direct contact, the information was obtained through secondary data. Data entry was done in CSPro software application and was analyzed in SPSS 20. The total number of registered Nepali dentists was 1803 with 419 specialists until June 2015. The male to female ratio was 1:1.46. Among all; 1318 (73%) were present in the country, 1047 (58%) were professionally active, and 1366 (76%) were below the age of 35 years. Among the professionals; 831 (79%) were employed in private sector and 601 (57%) worked in Kathmandu valley. The dentist-population ratio is decreasing exponentially in capital and major cities of Nepal however it remains very high in rural areas. Compared to other provinces,Province 6 and Province 7 lack service of dentists.

Acute febrile illness is common among those seeking medical care and is frequently treated empirically with the underlying illness remaining undiagnosed in resource-poor countries. A febrile illness study was conducted 2009-2010 to identify known and unknown pathogens circulating in Nepal. Study methods included diagnostic testing and preliminary ELISA screening of acute and convalescent samples for diseases both known and unknown to be circulating in Nepal, including West Nile virus (WNV). The molecular assays including Polymerase Chain Reaction (PCR), Sanger sequencing and ultra deep sequencing on MiSeq Illumina Platform were conducted to further confirm the presence of WNV. The study enrolled 2,046 patients presenting undifferentiated febrile illness with unknown etiology. Sera from 14 out of 2,046 patients were tested positive for west nile virus (WNV) by nested Reverse Transcription-Polymerase Chain Reaction (RT-PCR). Only two out of 14 cases were confirmed for the presence of WNV by sequencing and identified as WNV lineage 1 phylogentically. The two patients were adult males with fever and no neurological symptoms from Kathmandu and Bharatpur, Nepal. Two out of 2,046 serum samples contained fragments of WNV genome resembling WNV lineage 1, which is evidence of the continued spread of WNV which should be considered a possible illness cause in Nepal.

Objective To determine the risk factors for neonatal encephalopathy among term infants in a developing country. Design Unmatched case-control study. Setting Principal maternity hospital of Kathmandu, Nepal. Subjects All 131 infants with neonatal encephalopathy from a population of 21 609 infants born over an 18 month period, and 635 unmatched infants systematically recruited over 12 months. Main outcome measures Adjusted odds ratio estimates for antepartum and intrapartum risk factors. Results The prevalence of neonatal encephalopathy was 6.1 per 1000 live births of which 63% were infants with moderate or severe encephalopathy. The risk of death from neonatal encephalopathy was 31%. The risk of neonatal encephalopathy increased with increasing maternal age and decreasing maternal height. Antepartum risk factors included primiparity (odds ratio 2.0) and non-attendance for antenatal care (2.1). Multiple births were at greatly increased risk (22). Intrapartum risk factors included non-cephalic presentation (3.4), prolonged rupture of membranes (3.8), and various other complications. Particulate meconium was strongly associated with encephalopathy (18). Induction of labour with oxytocin was associated with encephalopathy in 12 of 41 deliveries (5.7). Overall, 78 affected infants (60%) compared with 36 controls (6%) either had evidence of intrapartum compromise or were born after an intrapartum difficulty likely to result in fetal compromise. A concentration of maternal haemoglobin of less than 8.0 g/dl in the puerperium was significantly associated with encephalopathy (2.5) as was a maternal thyroid stimulating hormone concentration greater than 5 mIU/l (2.1). Conclusions Intrapartum risk factors remain important for neonatal encephalopathy in developing countries. There is some evidence of a protective effect from antenatal care. The use of oxytocin in low income countries where intrapartum monitoring is suboptimal presents a major risk to the fetus. More work is

The prevalence of childhood overweight and obesity is increasing in low-and middle income countries such as Nepal. At the same time, high prevalence of chronic undernutrition persists leading to a double burden of malnutrition. To identify associations between the socioeconomic status of mothers, food security, the food safety environment within the household, and prevalence of stunting and overweight of the children. Statistical analysis of socioeconomic, food safety-related and anthropometric data from 289 mother-child dyads in an urban area of the Kathmandu Valley, Nepal. According to WHO standards, 26 % of the children, aged 0-59 months, were stunted, 10 % were underweight, and 6.6 % were either overweight or obese. Significantly more boys than girls were underweight (p = 0.004) and stunted (p < 0.001). The higher education level of mothers was associated with a higher height-for-age (HAZ) score in girls, but not with HAZ in boys. Irrespective of sex, children of mothers with highest education level had significantly lower BMI-for-age scores (BAZ) than those of mothers with low education levels. None of the food safety indicators were associated with either HAZ or the BAZ. The education level of mothers seems to be relevant to help reduce the double burden of malnutrition at least in some regions of Nepal. This should be taken into consideration when designing programmes to prevent both chronic undernutrition and non-communicable diseases.

Sex-selective abortion is expressly prohibited in Nepal, but limited evidence suggests that it occurs nevertheless. Providers' perspectives on sex-selective abortion were examined as part of a larger study on legal abortion in the public sector in Nepal. In-depth interviews were conducted with health care providers and administrators providing abortion services at four major hospitals (n = 35), two in the Kathmandu Valley and two in outlying rural areas. A grounded theory approach was used to code interview transcripts and to identify themes in the data. Most providers were aware of the ban on sex-selective abortion and, despite overall positive views of abortion legalization, saw sex selection as an increasing problem. Greater availability of abortion and ultrasonography, along with the high value placed on sons, were seen as contributing factors. Providers wanted to perform abortions for legal indications, but described challenges identifying sex-selection cases. Providers also believed that illegal sex-selective procedures contribute to serious abortion complications. Sex-selective abortion complicates the provision of legal abortion services. In addition to the difficulty of determining which patients are seeking abortion for sex selection, health workers are aware of the pressures women face to bear sons and know they may seek unsafe services elsewhere when unable to obtain abortions in public hospitals. Legislative, advocacy, and social efforts aimed at promoting gender equality and women's human rights are needed to reduce the cultural and economic pressures for sex-selective abortion, because providers alone cannot prevent the practice.

2011-01-01

Similar to other parts of Asia, the HIV epidemic in Nepal is concentrated among a small number of groups, including transgender people, or Metis. This study was conducted to explore the social context of stigma among Metis in Nepal to better understand their risk for HIV. Fourteen in-depth interviews were conducted with Metis in Kathmandu, Nepal. We found that stigma from families leading to rural-urban migration exposed Metis to discrimination from law enforcement, employers and sexual partners, which influenced their risk for HIV. Specific HIV-related risks identified were rape by law enforcement officers, inconsistent condom use and high reported numbers of sexual partners. These data point to an immediate need to work with law enforcement to reduce violence targeting Metis. HIV prevention, housing and employment outreach to Metis in rural areas and those who migrate to urban areas is also needed. Finally, there is a need for more research to determine the prevalence of HIV among Metis, to explore risk within sexual networks and to better understand of the relationship between Metis and their families in order to develop future programmes and interventions.

To analyze the sexual behavior, perceived risk of contracting STIs and HIV/AIDS, and protective behaviors of migrant workers aged 14-19 years in carpet and garment factories in the Kathmandu Valley, Nepal. A common assumption in Nepal is that young migrant workers experience an increase in vulnerability. Moving away from the social controls of family and community, they become exposed to a mixed-gender environment and therefore might initiate sex earlier or have more casual encounters than might otherwise be the case. The analysis is based on a representative sample survey of 1050 factory workers. Information was also obtained from 23 in-depth case histories. Both bivarite and multivariate techniques were applied to identify the factors associated with involvement in risky sexual behavior. Despite religious and cultural restrictions, one in five boys and one in eight unmarried girls reported experience of sexual intercourse. Early sexual experimentation, multiple partners, and low and irregular use of condoms are not uncommon. Instances of sexual exploitation by factory owners or managers were documented but were rare. Most nonregular sex partners were described as friends from the same factory or community. Despite high-risk behavior, relatively few young people considered themselves to be at risk of getting STIs or HIV/AIDS. Information on the possible consequences of unsafe sex is inadequate. Programs aimed at promotion of safer sex practices and life skill training that facilitates communication and utilization of sexual health services should target vulnerable migrant young people.

Atmospheric polycyclic aromatic hydrocarbons (PAHs) in urban areas have always been a global concern, as these areas are considered to be the source region. Despite studies on the concentrations of PAHs in water, soils and sediments, knowledge of the distribution patterns, seasonality and sources of PAHs in urban areas of Nepal remains limited. In this study, polyurethane foam passive air samplers were used to measure gas-phase PAH concentrations over different land types in three major cities of Nepal-namely, Kathmandu (the capital) and Pokhara (both densely populated cities), and Hetauda (an agricultural city). The average concentrations of ∑15PAHs in ng/m 3 were 16.1±7.0 (6.4-28.6), 14.1±6.2 (6.8-29.4) and 11.1±9.0 (4.1-38.0) in Kathmandu, Pokhara and Hetauda, respectively. Molecular diagnostic ratio analysis suggested that fossil fuel combustion was a common PAH source for all three cities. In addition to this, coal combustion in Kathmandu, vehicle emissions in Pokhara, and grass/wood combustion in Hetauda were also possible sources of PAHs. In terms of cancer risk from PAH inhalation, a religious site with intense incense burning, a brick production area where extensive coal combustion is common, and a market place with heavy traffic emission, were associated with a higher risk than other areas. There were no clear seasonal trends in atmospheric PAHs. The estimated cancer risk due to inhalation of gas-phase PAHs exceeded the USEPA standard at >90% of the sites. Copyright © 2017 Elsevier B.V.

2009-01-01

In this study we examine which factors predict internal and international migration from Chitwan, a flat valley located in the South-Central region of Nepal, seeking to measure the effect of theoretically specified variables such as human capital, social capital, physical capital, and neighborhood socioeconomic conditions while controlling for demographic variables. We use data from the Chitwan Valley Family Study (CVFS) to estimate a series of discrete time event history models of first and repeat migration to three competing destinations: other locations within Chitwan, other districts within Nepal, and places outside of Nepal. Results support hypotheses derived from neoclassical economics, the theory of new economics of migration, social capital theory, and cumulative causation theory. Our results underscore the need for a synthetic theoretical model that incorporates factors operating at the individual, household, and community levels. The use of multiple explanatory models yields a clearer picture of the forces driving internal and international migration from rural districts in developing nations such as Nepal.

Little is known about the epidemiology of typhoid and paratyphoid fever in Nepal. We aimed to elucidate the molecular and clinical epidemiology of Salmonella Paratyphi A in Nepal. Isolates were collected from 23 cases of bacteremia due to S. Paratyphi A between December 2014 and October 2015. Thirteen patients (57%) were male, and the median age was 21 years. None of the patients had an underlying chronic disease. All S. Paratyphi A isolates were sensitive to ampicillin, trimethoprim/sulfamethoxazole, ceftriaxone, and chloramphenicol. All isolates were resistant to nalidixic acid and were categorized as intermediately susceptible to levofloxacin. Phylogenetic analysis revealed close relatedness among the isolates, including several clonal groups, suggesting local spread. Patients with bacteremia due to S. Paratyphi A in Kathmandu, Nepal, were relatively young and nondebilitated. Improving control of S . Paratyphi infections should focus on effective infection control measures and selection of empirical therapy based on current resistance patterns.

The Gorkha Earthquake of M7.8 hit Nepal on April 25, 2015 at 11:56 am local time. The epicenter of this earthquake was Barpak, Gorkha, 80 km northwest of Kathmandu Valley. The main shock was followed by hundreds of aftershocks including M6.6 and M6.7 within 48 hours and M7.3 on May 12, 2015. According to the Government of Nepal, a total of 8,686 people lost their lives, 16,808 people injured, over 500,000 buildings completely collapsed and more than 250,000 building partially damaged. The National Society for Earthquake Technology - Nepal (NSET), a not-for-profit civil society organization that has been focused on earthquake risk reduction in Nepal for past 21 years, conducted various activities to support people and the government in responding to the earthquake disaster. The activities included: i) assisting people and critical facility institutions to conduct rapid visual building damage assessment including the training; ii) information campaign to provide proper information regarding earthquake safety; iii) support rescue organizations on search and rescue operations; and iv) provide technical support to common people on repair, retrofit of damaged houses. NSET is also involved in carrying out studies related to earthquake damage, geotechnical problems, and causes of building damages. Additionally, NSET has done post-earthquake detail damage assessment of buildings throughout the affected areas. Prior to the earthquake, NSET has been working with several institutions to improve seismic performance of school buildings, private residential houses, and other critical structures. Such activities implemented during the past decade have shown the effectiveness of risk reduction. Retrofitted school buildings performed very well during the earthquake. Preparedness activities implemented at community levels have helped communities to respond immediately and save lives. Higher level of earthquake awareness achieved including safe behavior, better understanding of

Assess visual impairment in school children of upper-middle socioeconomic status in Kathmandu for comparison with rural Jhapa District. Random selection of classes from secondary private schools in Kathmandu was used to identify the study sample. Children in 130 classes at 43 schools were enumerated using school records and examined between January-May 2006. Examinations included visual acuity testing, ocular motility evaluation, cycloplegic refraction, and examination of the external eye, anterior segment, media, and fundus. The principal cause was determined for eyes with uncorrected visual acuity < or = 20/40. A total of 4,501 children in grades 5-9 were enumerated; 4282 (95.1%) were examined. The prevalence of uncorrected, presenting, and best-corrected visual impairment (< or = 20/40) in the better eye was 18.6%, 9.1%, and 0.86%, respectively. Refractive error was a cause in 93.3% of children with uncorrected visual impairment, amblyopia 1.8%, retinal disorders 1.3%, other causes 0.3%, and unexplained causes 4.4%. Among children correctable in at least one eye, 46.3% presented without the necessary spectacles. Visual impairment with myopia (-0.50 diopters) ranged from 10.9% in 10 year-olds to 27.3% in 15 year-olds, compared to 0.5%-3.0% in rural Jhapa District. Myopic visual impairment was associated with grade level, female gender, parental education, parental spectacle usage, and Mongol ethnicity. Visual impairment with myopia among upper-middle socioeconomic school children in Kathmandu is higher than that in rural Nepal, and a public health problem because nearly half are without corrective spectacles. Effective strategies are needed to eliminate this easily treatable cause of visual impairment.

Background Communities in urban slums face multiple risks to their health. These are shaped by intermediary and structural determinants. Gaining a clear understanding of these determinants is a prerequisite for developing interventions to reduce the health consequences of urban poverty. With 828 million people living in slum conditions, the need to find ways to reduce risks to health has never been greater. In many low income settings, the kitchen is the epicentre of activities and behaviours which either undermine or enhance health. Methods We used qualitative methods of semi-structured interviews, observation and participatory workshops in two slum areas in Kathmandu, Nepal to gain women’s perspectives on the health risks they faced in and around their kitchens. Twenty one women were interviewed and four participatory workshops with a total of 69 women were held. The women took photographs of their kitchens to trigger discussions. Findings The main health conditions identified by the women were respiratory disease, gastrointestinal disease and burn injuries. Women clearly understood intermediary (psychosocial, material and behavioural) determinants to these health conditions such as poor ventilation, cooking on open fires, over-crowding, lack of adequate child supervision. Women articulated the stress they experienced and clearly linked this to health conditions such as heart disease and uptake of smoking. They were also able to identify protective factors, particularly social capital. Subsequent analysis highlighted how female headed-households and those with disabilities had to contend with greater risks to health. Conclusions Women living in slums are very aware of the intermediary determinants–material, behavioural and psycho-social, that increase their vulnerability to ill health. They are also able to identify protective factors, particularly social capital. It is only by understanding the determinants at all levels, not just the behavioural, that we

Background The presence of the recently introduced primary dengue virus vector mosquito Aedes aegypti in Nepal, in association with the likely indigenous secondary vector Aedes albopictus, raises public health concerns. Chikungunya fever cases have also been reported in Nepal, and the virus causing this disease is also transmitted by these mosquito species. Here we report the results of a study on the risk factors for the presence of chikungunya and dengue virus vectors, their elevational ceiling of distribution, and climatic determinants of their abundance in central Nepal. Methodology/Principal Findings We collected immature stages of mosquitoes during six monthly cross-sectional surveys covering six administrative districts along an altitudinal transect in central Nepal that extended from Birgunj (80 m above sea level [asl]) to Dhunche (highest altitude sampled: 2,100 m asl). The dengue vectors Ae. aegypti and Ae. albopictus were commonly found up to 1,350 m asl in Kathmandu valley and were present but rarely found from 1,750 to 2,100 m asl in Dhunche. The lymphatic filariasis vector Culex quinquefasciatus was commonly found throughout the study transect. Physiographic region, month of collection, collection station and container type were significant predictors of the occurrence and co-occurrence of Ae. aegypti and Ae. albopictus. The climatic variables rainfall, temperature, and relative humidity were significant predictors of chikungunya and dengue virus vectors abundance. Conclusions/Significance We conclude that chikungunya and dengue virus vectors have already established their populations up to the High Mountain region of Nepal and that this may be attributed to the environmental and climate change that has been observed over the decades in Nepal. The rapid expansion of the distribution of these important disease vectors in the High Mountain region, previously considered to be non-endemic for dengue and chikungunya fever, calls for urgent actions to

Abortion law in Nepal: the road to reform.

PubMed

Thapa, Shyam

2004-11-01

In 2002 Nepal's parliament passed a liberal abortion law, after nearly three decades of reform efforts. This paper reviews the history of the movement for reform and the combination of factors that contributed to its success. These include sustained advocacy for reform; the dissemination of knowledge, information and evidence; adoption of the reform agenda by the public sector and its leadership in involving other stakeholders; the existence of work for safe motherhood as the context in which the initiative could gain support; an active women's rights movement and support from international and multilateral organisations; sustained involvement of local NGOs, civil society and professional organisations; the involvement of journalists and the media; the absence of significant opposition; courageous government officials and an enabling democratic political system. The overriding rationale for reforming the abortion law in Nepal has been to ensure safe motherhood and women's rights. The first government abortion services officially began in March 2004 at the Maternity Hospital in Kathmandu; services will be expanded gradually to other public and private hospitals and private clinics in the coming years.

Segmentation of the Himalayan megathrust around the Gorkha earthquake (25 April 2015) in Nepal

We put the 25 April 2015 earthquake of Nepal (Mw 7.9) into its structural geological context in order to specify the role of the segmentation of the Himalayan megathrust. The rupture is mainly located NW of Kathmandu, at a depth of 13-15 km on a flat portion of the Main Himalayan Thrust (MHT) that dips towards the N-NE by 7-10°. The northern bound of the main rupture corresponds to the transition towards a steeper crustal ramp. This ramp, which is partly coupled during the interseismic period, is only locally affected by the earthquake. The southern bound of the rupture was near the leading edge of the Lesser Himalaya antiformal duplex and near the frontal footwall ramp of the upper Nawakot duplex. The rupture has been affected by transversal structures: on the western side, the Judi lineament separates the main rupture zone from the nucleation area; on the eastern side, the Gaurishankar lineament separates the 25 April 2015 rupture from the 12 May 2015 (Mw 7.2) rupture. The origin of these lineaments is very complex: they are probably linked to pre-Himalayan faults that extend into the Indian shield beneath the MHT. These inherited faults induce transverse warping of the upper lithosphere beneath the MHT, control the location of lateral ramps of the thrust system and concentrate the hanging wall deformation at the lateral edge of the ruptures. The MHT is therefore segmented by stable barriers that define at least five patches in Central Nepal. These barriers influence the extent of the earthquake ruptures. For the last two centuries: the 1833 (Mw 7.6) earthquake was rather similar in extent to the 2015 event but its rupture propagated south-westwards from an epicentre located NE of Kathmandu; the patch south of Kathmandu was probably affected by at least three earthquakes of Mw ⩾ 7 that followed the 1833 event a few days later or 33 years (1866 event, Mw 7.2) later; the 1934 earthquake (Mw 8.4) had an epicentre ∼170 km east of Kathmandu, may have propagated

Reassessing Catastrophic Infill of the Pokhara Valley, Nepal Himalaya

The Pokhara valley, home to Nepal's second largest city and a major tourist attraction (28°15'N, 83°58'E), is covered by 4-5 km3 and 50-100 m thick intramontane fan deposits that resulted from massive aggradation of the Seti Khola, a river draining the Annapurna Massif of the Greater Himalaya. Poorly sorted, gravelly fluvial facies intercalated with debris-flow and mud-flow facies known as the Pokhara Gravels attest to highly energetic transport conditions during one or several catastrophic flow events. In May 2012, a devastative flash flood/debris flow in the Seti Khola rekindled interest in the formation processes and timing of the Pokhara Gravels as they may provide constraints on the magnitudes and frequencies of similar past events. Interpretations of previous sedimentological work and radiocarbon dating (Yamanaka, 1982; Fort, 1987) culminated in the belief that the Pokhara Gravels were catastrophically emplaced only 500 to 1000 years ago, although the exact nature, timing, and triggers of the purported event(s) remain obscure. Specifically, it remains debated whether the Pokhara Gravels were deposited instantaneously, possibly within less than a year, or whether sedimentation was more protracted over perhaps decades to millennia. We present new geomorphological, sedimentological, geochemical, and radiocarbon data and re-assess a potential catastrophic infill of the Pokhara Valley during one or several high-magnitude events. Support for this scenario is given by laterally continuous long-runout (~40 km) debris-flow deposits topped by large (i.e. up to >11-m) boulders, a distinctly calcareous lithology diagnostic of a small Greater Himalayan source area tens of kilometres upstream, and by historical anecdotes of a large flood that destroyed an earlier settlement in the area. However, we show that dated outcrops of fine-grained sediments in tributaries blocked by the Pokhara Gravels yield asynchronous ages. Although our radiocarbon dates are consistent with

Methicillin-resistant Staphylococcus aureus is one of the most common causes of nosocomial infections. Due to its multidrug resistant nature; infections due to Methicillin-resistant Staphylococcus aureus are often very difficult to treat. Colonized health care workers are the important sources of Methicillin-resistant Staphylococcus aureus. The objectives of this study were to determine the nasal carriage rate of Methicillin-resistant Staphylococcus aureus among health care workers at Kathmandu Medical College and Teaching Hospital, Nepal and to assess their antimicrobial susceptibility patterns. A cross sectional study was conducted among 252 health care workers from July to November 2013. Mannitol salt agar was used to culture the nasal swabs. Antimicrobial susceptibility testing was performed by Kirby-Bauer disc diffusion technique following Clinical and Laboratory Standards Institute guidelines. Methicillin-resistant Staphylococcus aureus strains were confirmed by using cefoxitin disc and by determining the minimum inhibitory concentration of oxacillin by agar dilution method. Of 252 healthcare workers, 46(18.3%) were positive for Staphylococcus aureus among which 19(41.3%) were Methicillin-resistant Staphylococcus aureus carriers. Overall rate of nasal carriage of Methicillin-resistant Staphylococcus aureus was 7.5% (19/252).The higher percentages of lab personnel were nasal carriers of S. aureus (31.6%) and Methicillin-resistant Staphylococcus aureus (10.5%).The percentages of nasal carriage of S. aureus (35.7%) and Methicillin-resistant Staphylococcus aureus (14.3%) were highest in the health care workers from post operative department. Higher percentage of Methicillin-resistant Staphylococcus aureus were susceptible toward amikacin (100%) and vancomycin (100%) followed by cotrimoxazole (84.2%). High rates of nasal carriage of S. aureus and Methicillin-resistant Staphylococcus aureus were observed among the healthcare workers, which indicate the need of

A Thai Airbus, carrying 99 passengers and 14 crew members, traveling from Bangkok to Kathmandu, hit a mountain and crashed several minutes before landing. There were no survivors. Recovered human remains, none of which was easily identifiable, varied in size from a small piece of muscle to mutilated bodies. Of the 97 fragments, only 15 were sufficiently intact (albeit, only partially) to be designated as "bodies." Of the fragments and "bodies," only 11 were positively identified. Causes of death, although all traumatic, could not be stated accurately due to the degree of disintegration. Identification of human remains in these circumstances is a major problem for the pathologist.

Preliminary remote sensing assessment of the catastrophic avalanche in Langtang Valley induced by the 2015 Gorkha earthquake, Nepal

A major earthquake, measuring 7.8 Mw, occurred on April 25, 2015, in Lamjung district, central Nepal, causing more than 9,000 deaths and 23,000 injuries. During the event, termed the 2015 Gorkha earthquake, the most catastrophic collapse of the mountain side was reported in the Langtang Valley, located 60 km north of Kathmandu. In this collapse, a huge boulder-rich avalanche and a sudden air pressure wave traveled from a steep south-facing slope to the bottom of a U-shaped valley, resulting in more than 170 deaths. Accurate in-situ surveys are necessary to investigate such events, and to find out ways to avoid similar catastrophic events in the future. Geospatial information obtained from multiple satellite observations is invaluable for such surveys in remote mountain regions. In this study, we (1) identify the collapsed sediment using synthetic aperture radar, (2) conduct detailed mapping using high-resolution optical imagery, and (3) estimate sediment volumes from digital surface models in order to quantify the immediate situation of the avalanched sediment. (1) Visual interpretation and coherence calculations using Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2) images give a consistent area of sediment cover. Emergency observation was carried out the day after the earthquake, using the PALSAR-2 onboard the Advanced Land Observing Satellite-2 (ALOS-2, "DAICHI-2"). Visual interpretation of orthorectified backscatter amplitude images revealed completely altered surface features, over which the identifiable sediment cover extended for 0.73 km2 (28°13'N, 85°30'E). Additionally, measuring the decrease in normalized coherence quantifies the similarity between the pre- and post-event surface features, after the removal of numerous noise patches by focal statistics. Calculations within the study area revealed high-value areas corresponding to the visually identified sediment area. Visual interpretation of the amplitude images and the coherence

Resilience of refugees displaced in the developing world: a qualitative analysis of strengths and struggles of urban refugees in Nepal

PubMed Central

2011-01-01

Background Mental health and psychosocial wellbeing are key concerns in displaced populations. Despite urban refugees constituting more than half of the world's refugees, minimal attention has been paid to their psychosocial wellbeing. The purpose of this study was to assess coping behaviour and aspects of resilience amongst refugees in Kathmandu, Nepal. Methods This study examined the experiences of 16 Pakistani and 8 Somali urban refugees in Kathmandu, Nepal through in-depth individual interviews, focus groups, and Photovoice methodology. Such qualitative approaches enabled us to broadly discuss themes such as personal experiences of being a refugee in Kathmandu, perceived causes of psychosocial distress, and strategies and resources for coping. Thematic network analysis was used in this study to systematically interpret and code the data. Results Our findings highlight that urban refugees' active coping efforts, notwithstanding significant adversity and resulting distress, are most frequently through primary relationships. Informed by Axel Honneth's theory on the struggle for recognition, findings suggest that coping is a function beyond the individual and involves the ability to negotiate recognition. This negotiation involves not only primary relationships, but also the legal order and other social networks such as family and friends. Honneth's work was used because of its emphasis on the importance of legal recognition and larger structural factors in facilitating daily coping. Conclusions Understanding how urban refugees cope by negotiating access to various forms of recognition in the absence of legal-recognition will enable organisations working with them to leverage such strengths and develop relevant programmes. In particular, building on these existing resources will lead to culturally compelling and sustainable care for these populations. PMID:21943401

Background Enteric fever, a systemic infection caused by the bacteria Salmonella Typhi and Salmonella Paratyphi A, is endemic in Kathmandu, Nepal. Previous work identified proximity to poor quality water sources as a community-level risk for infection. Here, we sought to examine individual-level risk factors related to hygiene and sanitation to improve our understanding of the epidemiology of enteric fever in this setting. Methodology and principal findings A matched case-control analysis was performed through enrollment of 103 blood culture positive enteric fever patients and 294 afebrile community-based age and gender-matched controls. A detailed questionnaire was administered to both cases and controls and the association between enteric fever infection and potential exposures were examined through conditional logistic regression. Several behavioral practices were identified as protective against infection with enteric fever, including water storage and hygienic habits. Additionally, we found that exposures related to poor water and socioeconomic status are more influential in the risk of infection with S. Typhi, whereas food consumption habits and migration play more of a role in risk of S. Paratyphi A infection. Conclusions and significance Our work suggests that S. Typhi and S. Paratyphi A follow different routes of infection in this highly endemic setting and that sustained exposure to both serovars probably leads to the development of passive immunity. In the absence of a polyvalent vaccine against S. Typhi and S. Paratyphi A, we advocate better systems for water treatment and storage, improvements in the quality of street food, and vaccination with currently available S. Typhi vaccines. PMID:23991240

[The impact of population growth on Tamba Kosi, a Himalayan valley in Nepal].

PubMed

Verliat, S

1994-01-01

Two several-month-long stays in the isolated Tamba Kosi valley in Nepal in 1983 and 1986 allowed an assessment of the importance of changes in rural societies. In about 50 years, the oldest inhabitants of some villages have seen the number of houses quadruple. In the absence of reliable statistical data, the inhabitants say that the Tamba Kosi valley population has doubled in the last 25 years. This population growth exacerbates the multiethnic fight for good land (i.e., ground of modest slope, hot, and humid). Many people have emigrated, which has somewhat eased problems relative to population growth. Soil degradation, which is becoming more and more acute, drives the inhabitants to cut down trees and clear the land for cultivation of new plots. These new plots are running up against steep slopes and high altitude. Most families have barely two hectares, which must suffice to feed 5-6 people on average. This fuels intensification of agricultural production, resulting in low efficacy. Livestock mutilate forests with their hooves and teeth. The marked increase in the variety of livestock accelerates this destruction. Three types of building materials are used in this high valley: thatch, shingles (fir tree), and bamboo matting. The disappearance of wild grasses used to make thatch roofs and people moving to higher and higher altitudes resulted in use of shingles to make roofs. Buildings made of shingles, which demanded changes in construction techniques, changed the conception of homes. They became the preferred building type, which increased the demand for fir trees and deforestation. This lead to a demand for roofing material made of bamboo matting and another change in construction techniques. The retreat of the forest and disappearance of the most wanted plant species are the most spectacular impacts of population growth. This environmental degradation exacerbates erosion at all bioclimatic altitudes.

Due to the high temperature and extensive use of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), tropical cities could act as secondary sources of these pollutants and therefore received global concern. As compared with other tropical cities, studies on the air-soil exchange of OCPs, PCBs and PAHs in tropical Nepali cities remained limited. In the present study, 39 soil samples from Kathmandu (capital of Nepal) and 21 soil samples from Pokhara (second largest city in Nepal) were collected The soil concentrations of the sum of endosulfans (α- and β-endosulfans) ranged from 0.01 to 16.4 ng/g dw. Meanwhile, ∑dichlorodiphenyltrichloroethane (DDTs) ranged from 0.01 to 6.5 ng/g dw; ∑6PCBs from 0.01 to 9.7 ng/g dw; and ∑15PAHs from 17.1 to 6219 ng/g dw. High concentrations of OCPs were found in the soil of commercial land, while, high soil PAH concentrations were found on tourist/religious and commercial land. Combined the published air concentrations, and the soil data of this study, the directions and fluxes of air-soil exchange were estimated using a fugacity model. It is clear that Nepal is a country contributing prominently to secondary emissions of endosulfans, hexachlorobenzene (HCB), and low molecular weight (LMW) PCBs and PAHs. The flux for all the pollutants in Kathmandu, with ∑endosulfans up to 3553; HCB up to 5263; and ∑LMW-PAHs up to 24378 ng m -2  h -1 , were higher than those in Pokhara. These high flux values indicated the high strength of Nepali soils to act as a source. Copyright © 2018 Elsevier Ltd. All rights reserved.

Infection control remains a key challenge for Tuberculosis (TB) control program with an increased risk of TB transmission among health care workers (HCWs), especially in settings with inadequate TB infection control measures. Poor knowledge among HCWs and inadequate infection control practices may lead to the increased risk of nosocomial TB transmission. An institution-based cross-sectional survey was conducted in 28 health facilities providing TB services in the Kathmandu Valley, Nepal. A total of 190 HCWs were assessed for the knowledge, attitudes and practices on TB infection control using a structured questionnaire. The level of knowledge on TB infection control among almost half (45.8%) of the HCWs was poor, and was much poorer among administration and lower level staff. The knowledge level was significantly associated with educational status, and TB training and/or orientation received. The majority (73.2%) of HCWs had positive attitude towards TB infection control. Sixty-five percent of HCWs were found to be concerned about being infected with TB. Use of respirators among the HCWs was limited and triage of TB suspects was also lacking. Overall knowledge and practices of HCWs on TB infection control were not satisfactory. Effective infection control measures including regular skill-based training and/or orientation for all categories of HCWs can improve infection control practices in health facilities.

In South Asian countries such as Nepal, India, and Bangladesh, pollution of rivers is more severe and critical near urban stretches due to huge amounts of pollution load discharged by urban activities. The Bagmati River in the Kathmandu valley, the Yamuna River at Delhi, and peripheral rivers (mainly Buriganga River) of Dhaka suffer from severe pollution these days. The observed dry season average of biochemical oxygen demand (BOD) in all these rivers is in the range of 20-30 mg/liter and total coliform are as high as 104-105 MPN/100 ml. Per capita pollution load discharge of urban areas has been estimated to be about 31, 19, and 25 g BOD/capita/day in Bagmati, Yamuna, and the rivers of Dhaka, respectively. Regression analysis reveals pollution loads steadily increasing nearly in step with the trend in urbanization. The dissolved oxygen (DO) level of the Bagmati and Buriganga rivers is declining at an average annual rate of nearly 0.3 mg/liter/year. Unplanned urbanization and industrialization occurring in these cities may be largely responsible for this grave situation. Inadequate sewerage, on-site sanitation, and wastewater treatment facilities in one hand, and lack of effective pollution control measures and their strict enforcement on the other are the major causes of rampant discharge of pollutants in the aquatic systems.

Men having sex with men are hidden population in Nepal due to existing of stigma and discrimination in social, economic and others aspects. Due to present stigma and discrimination majority of men having sex with men do not have access to HIV/AIDS prevention programs that lead to unsafe sexual behavior.The objective of the study was to explore self-perception of stigma and discrimination among men having sex with men in Kathmandu valley. This is a qualitative study. Study was carried out between July 2010 and December 2010 in Kathmandu Valley, Nepal. During study 3 focus group discussions were conducted to explore stigma and discrimination of the respondents in their families, work place, health facilities, from law reinforcement body, and to explore methods of adaptation of men who have sex with men to stigma and discrimination in different areas of their life. A focus group discussions guideline was used for the discussion. Majority of the respondents who reported about discrimination from family members, in work place, in health care facilities and from law reinforcement body were Transgender (Meti). Many of respondents noticed that in some aspects discrimination seems to be decreasing due to rising awareness of homosexual relationship in the society. In spite on rising awareness among society regarding homosexual relationship there is still lots of stigma and discrimination faced by MSMs in all aspects of their life.

Large CO2 flux has been found in the Trisuli Valley, North of Kathmandu, Central Nepal, in 2005. This leakage zone is located in the vicinity of the Syabru-Bensi hot springs, and is characterized by an average flux of CO2 of 6500±1100 g m-2 day-1 over an area of 15 m × 15 m (Perrier et al., Earth and Planetary Science Letters, 2009). The site is also located close to the Main Central Thrust Zone (MCT Zone), one of the large Himalayan thrust, connected at depth to the Main Himalayan Thrust, the main thrust currently accommodating the India-Tibet collision (Bollinger et al., Journal of Geophysical Research, 2004). Isotopic carbon ratios (δ13C) indicate that this CO2 may come from metamorphic reactions at about 15 km of depth (Becker et al., Earth and Planetary Science Letters, 2008; Evans et al., Geochemistry Geophysics Geosystems, 2008). Actually, this zone was originally found because of the large δ13C found in the water of the hot springs suggesting degassing (Evans et al., Geochemistry Geophysics Geosystems, 2008). In 2007, another zone of CO2 discharge was discovered 250 m away from the main Syabru-Bensi hot springs. This new zone, located next to the road and easy to access all over the year, was intensely studied, from the end of 2007 to the beginning of 2009. In this zone, an average value of CO2 flux of 1700±300 g m-2 d-1 was obtained over an area of about 40 m × 10 m. Using CO2 flux data from repeated measurements, similar flux values were observed during the dry winter season and the wet summer period (monsoon) (Girault et al., Journal of Environmental Radioactivity, 2009). Thus, in addition to fundamental issues related to global CO2 balance in orogenic belts and tectonically active zones, these small scale (100-meter) CO2 discharge sites emerge as a potentially useful laboratory for detailed methodological studies of diffusive and advective gas transport. Recently, the search for further gas discharge zones has been carried out using various clues

Nepal the "Shangri-La" in the lap of the Himalayas is gearing up for modern times as it starts rebuilding after a decade of senseless violence and destruction. The nation one of the poorest in the global development index is rich in natural resources and biodiversity. Reports of medicinal plants far exceeding those recorded and reported so far are encouraging and at the same time concerns for medicinal plants under threat as a result of overexploitation are emerging from Nepal. The harsh mountain terrains, lack of industrialization and harnessing potentiality of its areas of strength; water; natural resources and tourism make it poor in per capita income which averages ~ 300 US$, with half the population living under >1$ a day. Nepal is beginning to realize that the way ahead is only possible through the path of Science and Technology (ST). Nepal Academy of Science and Technology formerly known as Royal Academy of Science and Technology organized the fifth national conference held every 4 years that took place in the capital Kathmandu during November 10-12, 2008. The ST initiation event saw the participation of ~ 1400 people representing over 150 organizations from the country and experts from abroad. The theme for the fifth national meet was "Science, Technology and Innovation for Prosperous Nepal". Complementary and Alternative Medicine (CAM) was an important theme in the event as the realization for the need of ST research focused in CAM for harnessing the chemo diversity potential was univocally approved.

To explore the prevalence, perpetrator characteristics and the correlates of child abuse in Kathmandu, Nepal. For this cross-sectional study, we translated the internationally validated questionnaire developed by the International Society for Prevention of Child Abuse and Neglect, Child Abuse Screening Tool-Child Home into Nepali. We added questions on descriptive information about students and their family to the questionnaire. We recruited students from 20 schools selected randomly-2 from each of the 10 electoral constituencies of Kathmandu district. In each school, we administered the questionnaires to the students in a classroom selected randomly. To assess the correlates, we ran multilevel multivariable logistic regression models, stratified by schools. Among the 962 students, 88.88% had experience of at least one form of abuse throughout their lifetime. Psychological abuse was the most prevalent form of abuse (previous year: 75.19%; lifetime: 76.15%) followed by physical abuse, exposure to violence, neglect and sexual abuse. Adults were the most common perpetrators of child abuse (37.55%). The correlates identified in this study mostly aligned with the global literature on correlates of abuse. Female students were more likely to report neglect (previous year: adjusted OR (AOR) 1.50, 95% CI 1.10 to 2.04; lifetime: AOR 1.49, 95% CI 1.10 to 2.02), but no gender difference was observed with other forms of abuse. Students living with a single parent had a greater likelihood of exposure to violence (previous year: AOR 2.55, 95% CI 1.31 to 4.94; lifetime: AOR 2.77, 95% CI 1.39 to 5.53), neglect (previous year: AOR 2.01, 95% CI 1.10 to 3.69; lifetime: AOR 2.08, 95% CI 1.14 to 3.81) and sexual abuse (previous year: AOR 3.03, 95% CI 1.45 to 6.37; lifetime: AOR 2.49, 95% CI 1.21 to 5.14). Over 88% of students reported experiencing child abuse in the home in one or more forms throughout their lifetime. Delineating the reasons for the high burden and its

Refractive errors are the one of the most common visual disorders found worldwide in school going children and also it is one of the causes of blindness. It can easily be prevented, if timely proper measures are taken. In Kathmandu valley and Mechi Zone of Nepal, the distribution of refractive errors was found to be very high. No records are available from the Western part of Nepal. Considering the importance of the refractive errors the present study had been undertaken in Pokhara city. 964 subjects (474 boys, 490 girls) were selected between age groups 10 to 19 years from 6 schools representing different region of Pokhara. After Preliminary examination: on acuity of vision with Snellen's and Jaeger's charts, the subjects were referred to the Manipal Teaching Hospital, Pokhara for confirmation of the refractive errors. Sixty two schools children (6.43%), out of 964 had refractive errors. The myopia was found to be most common (4.05%). The refractive errors were found more in Private school children (9.29%) than Government school children (4.23%), which is statistically significant (P < 0.05). More boys (7.59%) were found to have suffered from refractive errors than girls (5.31%). Further, children with vegetarian diet (10.52%) had greater number of refractive errors than non-vegetarian diet children (6.17%). In the present study, percentage distribution of myopia was found to be higher (4.05%) than the hyperopia (1.24%) and astigmatism (1.14%). Interestingly, in the present study the refractive errors were found significantly higher in Private schools children than Government schools because the children who read in Private schools have higher socioeconomic status; spend more time in home work, watching Television and Computer as compared to government schools children. These near activities of the eyes causes stress on eyes of the children and might be one of the causes of developing myopia.

We conducted a study to examine the effect of seasonal variations and the disruptive effects of the 2015 Nepal earthquake on microbial communities associated with drinking water sources. We first characterized the microbial communities of water samples in two Nepali regions (Kathmandu and Jhapa) to understand the stability of microbial communities in water samples collected in 2014. We analyzed additional water samples from the same sources collected from May to August 2015, allowing the comparison of samples from dry-to-dry season and from dry-to-monsoon seasons. Emphasis was placed on microbes responsible for maintaining the geobiochemical characteristics of water (e.g., ammonia-oxidizing and nitrite-oxidizing bacteria and archaea and sulfate-reducing bacteria) and opportunistic pathogens often found in water (Acinetobacter). When examining samples from Jhapa, we identified that most geobiochemical microbe populations remained similar. When examining samples from Kathmandu, the abundance of microbial genera responsible for maintaining the geobiochemical characteristics of water increased immediately after the earthquake and decreased 8 months later (December 2015). In addition, microbial source tracking was used to monitor human fecal contamination and revealed deteriorated water quality in some specific sampling sites in Kathmandu post-earthquake. This study highlights a disruption of the environmental microbiome after an earthquake and the restoration of these microbial communities as a function of time and sanitation practices.

Men in patriarchal societies of developing countries are often identified as decision makers in all aspects of day-to-day life. The study explores the factors associated with male involvement in ANC, birth plans, exclusive breastfeeding and immunization of children. A cross-sectional survey was conducted among 2178 married males between May and December 2010 in Kathmandu, Nepal. Twenty one clusters were selected for data collection using structured questionnaire. Adjusted odds ratios (AORs) and 95% confidence intervals (95% CI) of associated factors were estimated by stepwise backward likelihood ratio method. This study determined the percentage of males who accompanied their partners for ANC (39.3%), arranged SBA (47.9%) and accompanied them for child immunization (10.9%). Factors found associated with respect to different activities were as follows: accompanied their partners on antenatal visits - uneducated or primary level education (AOR, 5.68, 95% CI, 4.44-7.27), income NPR 5001 (1USD = 85 NPR) or above (1.47, 1.20-1.80) and aged above 25 years (2.51, 1.89-3.33); arranged money for delivery - uneducated or primary level education (7.34, 5.84-9.23), income NPR 5001 or above (1.80, 1.48-2.20) and aged above 25 years (1.55, 1.18-2.03); arranged SBA - uneducated or primary level education (17.14, 12.65-23.22) and income NPR 5001 or above (2.89, 2.36-3.54); arranged transportation - uneducated or primary level education (17.65, 11.84-26.32), income NPR 5001 or above (1.69, 1.40-2.04) and aged above 25 years (1.69, 1.27-2.24); encouraged exclusive breast feeding - uneducated or primary level education (5.48, 4.39-6.83) and aged above 25 years (1.35, 1.03-1.77); accompanied their partners for immunization their children - uneducated or primary level education (3.88, 2.53-5.96) and aged above 25 years (1.72, 1.11-2.64).

This report provides a detailed account of assessments performed in May and June 2015 and focuses on valley-blocking landslides because they have the potential to pose considerable hazard to many villages in Nepal. First, we provide a seismological background of Nepal and then detail the methods used for both external and in-country data collection and interpretation. Our results consist of an overview of landsliding extent, a characterization of all valley-blocking landslides identified during our work, and a description of video resources that provide high resolution coverage of approximately 1,000 kilometers (km) of river valleys and surrounding terrain affected by the Gorkha earthquake sequence. This is followed by a description of site-specific landslide-hazard assessments conducted while in Nepal and includes detailed descriptions of five noteworthy case studies. Finally, we assess the expectation for additional landslide hazards during the 2015 summer monsoon season.

Options for developing modernized geodetic datum for Nepal following the April 25, 2015 Mw7.8 Gorkha earthquake

Along with the damage to buildings and infrastructure, the April 25, 2015 Mw7.8 Gorkha earthquake caused significant deformation over a large area of eastern Nepal with displacements of over 2 m recorded in the vicinity of Kathmandu. Nepal currently uses a classical datum developed in 1984 by the Royal (UK) Engineers in collaboration with the Nepal Survey Department. It has served Nepal well; however, the recent earthquakes have provided an impetus for developing a semi-dynamic datum that will be based on ITRF2014 and have the capacity to correct for tectonic deformation. In the scenario we present here, the datum would be based on ITRF2014 with a reference epoch set some time after the end of the current sequence of earthquakes. The deformation model contains a grid of the secular velocity field combined with models of the Gorkha Earthquake and the May 12 Mw7.3 aftershock. We have developed a preliminary velocity field by collating GPS derived crustal velocities from four previous studies for Nepal and adjacent parts of China and India and aligning them to the ITRF. Patches for the co-seismic part of the deformation for the Gorkha earthquake and the May 12, 2015 Mw 7.2 aftershock are based on published dislocation models. High order control would be a CORS network based around the existing Nepal GPS Array. Coordinates for existing lower order control would be determined by readjusting existing survey measurements and these would be combined with a series of new control stations spread throughout Nepal.

Premarital sexual behavior among male college students of Kathmandu, Nepal.

In Nepal, as in other Asian countries, the issue of sexuality still remains a taboo. Despite this fact, an increasing number of sexual activities is being reported by Nepalese students. This trend warrants serious and timely attention. Due to the sensitivity of the topic of premarital sexuality, youth receive inadequate education, guidance and services on reproductive health. The main objectives of this paper are to explore the sexual behavior especially focusing on prevalence of premarital sex among college men and to investigate the factors surrounding premarital sexual behavior. A cross-sectional survey of college students was conducted in April-May 2006. A self-administered questionnaire was completed by 573 male students. Association between premarital sex and the explanatory variables was assessed in bivariate analysis using Chi-square tests. The associations were further explored using multivariate logistic analysis. Despite the religious and cultural restrictions, about two-fifths of survey respondents (39%) reported that they have had premarital sex. The study has also shown that substantial proportions of students indulge in sexual activities as well as risky sexual behavior. Sex with commercial sex workers, multiple sex partners, and inconsistence use of condom with non-regular partner was common among the students. Less than two in five male students (57%) had used condom at the first sexual intercourse.The prevalence of premarital sex varied on different settings. Older students aged 20 and above were more likely to have premarital sex compared with younger students aged 15-19. Men who had liberal attitude towards male virginity at marriage were almost two times more likely to have engaged in premarital sex compared to their counterparts who have conservative attitude towards male virginity at marriage. Moreover, those students who believe in Hindu religion were more than two times (OR = 2.5) more likely to have premarital sex compared with those who

To identify potential environmental drivers of Japanese Encephalitis virus (JE) transmission in Nepal, we conducted an ecological study to determine the spatial association between 2005 Nepal JE incidence, and climate, agricultural, and land-cover variables at district level. District-level data on JE cases were examined using Local Indicators of Spatial Association (LISA) analysis to identify spatial clusters from 2004 to 2008 and 2005 data was used to fit a spatial lag regression model with climate, agriculture and land-cover variables. Prior to 2006, there was a single large cluster of JE cases located in the Far-West and Mid-West terai regions of Nepal. After 2005, the distribution of JE cases in Nepal shifted with clusters found in the central hill areas. JE incidence during the 2005 epidemic had a stronger association with May mean monthly temperature and April mean monthly total precipitation compared to mean annual temperature and precipitation. A parsimonious spatial lag regression model revealed, 1) a significant negative relationship between JE incidence and April precipitation, 2) a significant positive relationship between JE incidence and percentage of irrigated land 3) a non-significant negative relationship between JE incidence and percentage of grassland cover, and 4) a unimodal non-significant relationship between JE Incidence and pig-to-human ratio. JE cases clustered in the terai prior to 2006 where it seemed to shift to the Kathmandu region in subsequent years. The spatial pattern of JE cases during the 2005 epidemic in Nepal was significantly associated with low precipitation and the percentage of irrigated land. Despite the availability of an effective vaccine, it is still important to understand environmental drivers of JEV transmission since the enzootic cycle of JEV transmission is not likely to be totally interrupted. Understanding the spatial dynamics of JE risk factors may be useful in providing important information to the Nepal

Thirty-five in-depth, semi-structured interviews were conducted with female, street-based, commercial sex workers in Kathmandu, Nepal. The framework of structural violence guided this study in identifying the structural context that impacts the female sex workers' lives and may cause harm to their health. Structural violence in health care was revealed through thematic analysis as (a) discrimination, (b) forced choice, and (c) limitations to health information sources. Lived experiences highlight how the sex workers engaged with structural limitations in health care access, services, and utilization. Structural violence conveys a message about who is entitled to health care and what a society emphasizes and expects regarding acceptable health behavior. Examining the structural violence highlighted how the sex workers negotiated, understood, and engaged with structural limitations in health care access, services, and utilization. © The Author(s) 2015.

On 25th April, 2015 a hazardous earthquake of moment magnitude 7.9 occurred in Nepal. Accelerographs were used to record the Nepal earthquake which is installed in the Kumaon region in the Himalayan state of Uttrakhand. The distance of the recorded stations in the Kumaon region from the epicenter of the earthquake is about 420-515 km. Modified semi-empirical technique of modeling finite faults has been used in this paper to simulate strong earthquake at these stations. Source parameters of the Nepal aftershock have been also calculated using the Brune model in the present study which are used in the modeling of the Nepal main shock. The obtained value of the seismic moment and stress drop is 8.26 × 1025 dyn cm and 10.48 bar, respectively, for the aftershock from the Brune model .The simulated earthquake time series were compared with the observed records of the earthquake. The comparison of full waveform and its response spectra has been made to finalize the rupture parameters and its location. The rupture of the earthquake was propagated in the NE-SW direction from the hypocenter with the rupture velocity 3.0 km/s from a distance of 80 km from Kathmandu in NW direction at a depth of 12 km as per compared results.

Population Mobility and Spread of HIV Across the Indo-Nepal Border

The article reviews information on the epidemiology of HIV/AIDS and behavioural networking to examine the role of population mobility in spreading HIV across the Indo-Nepal border. Documents were collected through a systematic search of electronic databases and web-based information resources, and the review focuses on studies about types of the virus, prevalence of HIV, and sexual and injecting networking. HIV-1 (subtype C) and HIV-2 were identified in Nepal. The prevalence of HIV was higher among male labour migrants and female sex workers (FSWs) who returned from India, especially from Mumbai, than in similar non-migrant groups. In the early 2000s, about 6–10% of Mumbai returnee men, compared to up to 4% of India returnee men and up to 3% of non-migrant men in the far-west Nepal, were identified with HIV. Likewise, when the prevalence of HIV among sex workers in Kathmandu was found to be 17% in 1999–2000, up to 44% of India returnee and 73% of Mumbai returnee FSWs were identified with the virus. These data are, however, based on small samples with questionable representativeness of the target populations and need to be interpreted cautiously. They also generate a biased impression that HIV was coming into Nepal from India. Recently, the possibility of a two-way flow of HIV across the Indo-Nepal border through injecting and sexual networking have been indicated by serological and behavioural data from a south-eastern cluster of Nepal and a north-eastern district of India. Although similar behavioural networks exist along other segments of the border, serological data are unavailable to assess whether and how extensively this phenomenon has caused the spread of HIV. Collaborative research and interventions covering both sides of the border are desirable to fully understand and address the prospect of HIV epidemics associated with cross-border population mixing.

Pseudomonas aeruginosa and Acinetobacter spp. are found to be associated with biofilm and metallo-β-lactamase production and are the common causes of serious infections mainly in hospitalized patients. So, the main aims of this study were to determine the rates of biofilm production and metallo beta-lactamase production (MBL) among the strains of Pseudomonas aeruginosa and Acinetobacter spp. isolated from hospitalized patients. A total of 85 P. aeruginosa isolates and 50 Acinetobacter spp. isolates isolated from different clinical specimens from patients admitted to Shree Birendra Hospital, Kathmandu, Nepal from July 2013 to May 2014 were included in this study. The bacterial isolates were identified with the help of biochemical tests. Modified Kirby-Bauer disc diffusion technique was used for antimicrobial susceptibility testing. Combined disc diffusion technique was used for the detection of MBL production, while Congo red agar method and tube adherence method were used for detection of biofilm production. Around 16.4% of P. aeruginosa isolates and 22% of the strains of Acinetobacter spp. were metallo β-lactamase producers. Out of 85 P. aeruginosa isolates, 23 (27.05%) were biofilm producers according to tube adherence test while, only 13 (15.29%) were biofilm producers as per Congo red agar method. Similarly, out of 50 Acinetobacter spp. 7 (14%) isolates were biofilm producers on the basis of tube adherence test, while only 5 (10%) were positive for biofilm production by Congo red agar method. Highest rates of susceptibility of P. aeruginosa as well as Acinetobacter spp. were seen toward colistin. In our study, biofilm production and metallo beta-lactamase production were observed among Pseudomonas aeruginosa and Acinetobacter spp. However, no statistically significant association could be established between biofilm production and metallo beta-lactamase production.

lthough Himalayan glaciers are of particular interest interms of future water supplies, regional climate changes, and sea-level rises, little is known about them due to lack of reliable and consistent data. There is a need for monitoring these glaciers to bridge this knowledge gap and to provide field measurements necessary to calibrate and validate the results from different remote sensing operations. Therefore, glaciological observations have been carried out by the Cryosphere Monitoring Project (CMP) since September 2011 on Rikha Samba Glacier in Hidden valley, Mustang district in western Nepal in order to study its annual mass balance. This paper presents the first results of that study. There are 10 glaciers in Hidden Valley, named G1, G2, G3, up to G10. Of these, G5 is the Rikha Samba Glacier, which has the largest area (5.37 km2) in this valley and the highest and lowest altitudes (6,476 and 5,392 m a.s.l., respectively). The glacier mass balance discussed in this paper was calculated using the glaciological method and the equilibrium line altitude (ELA).The glacier showed a negative annual point mass balance along the longitudinal profile of its lower part from September 10, 2011 to October 3, 2012. Stake measurements from October 4, 2012 to September 30, 2013 indicated a negative areal average of annual mass balance -0.088±0.019 m w.e. for the whole glacier. Based on these observations, the ELA of the Rikha Samba Glacier is estimated at 5,800 m a.s.l. in 2013. This negative balance may be due to rising air temperatures in the region, which have been incrementally rising since 1980 accompanied by little or no significant increase in precipitation in that period. The negative mass balance confirms the general shrinking trend of the glacier.

Indian-origin rhesus macaques (Macaca mulatta) have long served as an animal model for the study of human disease and behavior. Given the current shortage of Indian-origin rhesus, many researchers have turned to rhesus macaques from China as a substitute. However, a number of studies have identified marked genetic differences between the Chinese and Indian animals. We investigated the genetic characteristics of a third rhesus population, the rhesus macaques of Nepal. Twenty-one rhesus macaques at the Swoyambhu Temple in Kathmandu, Nepal, were compared with more than 300 Indian- and Chinese-origin rhesus macaques. The sequence analyses of two mitochondrial DNA (mtDNA) loci, from the HVS I and 12 S rRNA regions, showed that the Nepali animals were more similar to Indian-origin than to Chinese-origin animals. The distribution of alleles at 24 short tandem repeat (STR) loci distributed across 17 chromosomes also showed greater similarity between the Nepali and Indian-origin animals. Finally, an analysis of seven major histocompatibility complex (MHC) alleles showed that the Nepali animals expressed Class I alleles that are common to Indian-origin animals, including Mamu-A*01. All of these analyses also revealed a low level of genetic diversity within this Nepali rhesus sample. We conclude that the rhesus macaques of Nepal more closely resemble rhesus macaques of Indian origin than those of Chinese origin. As such, the Nepali rhesus may offer an additional resource option for researchers who wish to maintain research protocols with animals that possess key genetic features characteristic of Indian-origin rhesus macaques. 2005 Wiley-Liss, Inc.

Nepal was struck by devastating earthquakes in April-May 2015, followed by the India-Nepal border blockade later that year. We used the United Nations Commodity Trade Statistics (UN Comtrade) database to analyse exports of various health commodities from India to Nepal from January 2011-September 2016. We used time-series regressions of trading volume vs. unit price to ask how well Nepal's trading history with India prior to the earthquake and blockade was able to predict unit prices of health commodities imported into Nepal during and after the earthquake and the blockade. Regression residuals were used to quantify the extent to which the blockade impacted the price of healthcare commodities crossing into Nepal. During the blockade period (September 2015-early February 2016), the volume of all retail medicines traded across the India-Nepal border was reduced by 46.5% compared to same months in 2014-2015. For medical dressings, large volumes were exported from India to Nepal during and shortly after the earthquakes (May-June 2015), but decreased soon thereafter. During the earthquake, the difference between observed and predicted values of unit price (residuals) for all commodities show no statistical outliers. However, during the border blockade, Nepal paid USD 22.3 million more for retail medicines than one would have predicted based on its prior trading history with India, enough to provide healthcare to nearly half of Kathmandu's citizens for 1 year. The India-Nepal blockade was a geopolitical natural experiment demonstrating how a land-locked country is vulnerable to the vagaries of its primary trading partner. Although short-lived, the blockade had an immediate impact on traded medicine volumes and prices, and provided a large opportunity cost with implications for public health.

The Himalayas mountains, the highest in the world, offer exceptional landscapes, characterized by a large bio- and geo-diversity that should be preserved. Besides World Heritage Sites, recognized by UNESCO and inscribed for their outstanding universal value, a series of National Parks (Khumbu, Langtang, etc.) and Conservation areas (e.g. ACAP…) have been created by the Nepal Government, with the aim of integrating protection, education and sustainable development, in order to protect environmental heritages (flora, fauna, geosites), together with local culture and history, hence encouraging better knowledge and perception of the landscape elements by the visitors in connection with local people. The Himalayas, the result of the India-Asia plates collision, may also be considered both as real outdoor laboratory and museum, where geodynamic activity can be directly tackled and interpreted at different spatial and time scales by scientists. Their findings should be « translated » in simple words and sketches, in such a way that travelers, both local visitors and foreign trekkers, may learn along their itinerary. The conception of posters to be set in specific sites (outcrops and rock types, geological and geomorphological processes, such as major faults, landslides, relicts of glaciation etc.) is certainly the best way to promote geosciences and bring an additional value to travels across the Nepal Himalayas. The Department of Mines and Geology has taken the initiative of such a project. We present here a few examples of such geosites that would worth being illustrated along the famous trail, recently transformed as a motorable road, across the Kali Gandaki valley (Myadi and Mustang districts). On the basis of their geomorphic activity and their significance for local population, we have selected a few scenic places of significant scientific and educational interest (not exhaustive list).

Inequality in access to quality healthcare is a major health policy challenge in many low- and middle-income countries. This study aimed to identify the major sources of inequity in healthcare utilization using a population-based household survey from urban Nepal. A cross-sectional survey was conducted covering 9177 individuals residing in 1997 households in five municipalities of Kathmandu valley between 2011 and 2012. The concentration index was calculated and a decomposition method was used to measure inequality in healthcare utilization, along with a horizontal inequity index (HI) to estimate socioeconomic inequalities in healthcare utilization. Results showed a significant pro-rich distribution of general healthcare utilization in all service providers (Concentration Index: 0.062, P < 0.001; HI: 0.029, P < 0.05) and private service providers (Concentration Index: 0.070, P < 0.001; HI: 0.030, P < 0.05). The pro-rich distribution of probability in general healthcare utilization was attributable to inequalities in the level of household economic status (percentage contribution: 67.8%) and in the self-reported prevalence of non-communicable diseases such as hypertension (36.7%) and diabetes (14.4%). Despite the provision of free services by public healthcare providers, our analysis found no evidence of the poor making more use of public health services (Concentration Index: 0.041, P = 0.094). Interventions to reduce the household economic burden of major illnesses, coupled with improvement in the management of public health facilities, warrant further attention by policy-makers.

During SusKat-ABC (Sustainable Atmosphere for the Kathmandu Valley-Atmospheric Brown Clouds) field campaign conducted in the winter of 2012-2013, a comprehensive study was carried out to characterize the chemical composition of ambient Kathmandu air for speciated VOCs by deploying a Proton Transfer Reaction Time of Flight Mass Spectrometer (PTR-TOF-MS), the first time to be deployed in South Asia. Due to its high mass resolution (m/Δm > 4200) and temporal resolution (1 minute), 71 ion peaks were detected in the PTR-TOF-MS mass scan data, highlighting the chemical complexity of ambient air in the Valley. Of the 71, 38 species were found to have campaign average concentrations > 200 ppt and were identified based on their spectral characteristics, ambient diel profiles and correlation with specific emission tracers. Distinct diel profiles were observed for the nominal isobaric compounds isoprene (m/z=69.070) and furan (m/z=69.033). Comparison with several sites elsewhere in the world showed mixing ratios of acetaldehyde (~ 9 ppb), acetonitrile (~1 ppb) and isoprene (~ 1 ppb) to be among the highest measured anywhere in the world. Two "new" ambient compounds namely, methanamide (m/z = 46.029) and acetamide (m/z=60.051) which can photochemically produce isocyanic acid in the atmosphere, are reported in this study alongwith nitromethane (a tracer for diesel exhaust) and ketene (a very reactive compound). Two distinct periods were identified during the campaign based on high daytime biogenic emissions of isoprene even in winter and biomass fired brick kiln emissions of acetonitrile, benzene and isocyanic acid. Biomass burning and biomass fired brick kiln emissions were found to be the dominant source for compounds such as propyne, propene, benzene and propanenitrile which correlated strongly with biomass burning tracer acetonitrile (r2 > 0.7). The calculated total VOC OH reactivity was dominated by acetaldehyde (20.1%), ketene (ethenone) (17.1%), isoprene (16.8 %) and

Sudden impact disasters often result in the displacement of large numbers of people. These movements can occur prior to events, due to early warning messages, or take place post-event due to damages to shelters and livelihoods as well as a result of long-term reconstruction efforts. Displaced populations are especially vulnerable and often in need of support. However, timely and accurate data on the numbers and destinations of displaced populations are extremely challenging to collect across temporal and spatial scales, especially in the aftermath of disasters. Mobile phone call detail records were shown to be a valid data source for estimates of population movements after the 2010 Haiti earthquake, but their potential to provide near real-time ongoing measurements of population displacements immediately after a natural disaster has not been demonstrated. A computational architecture and analytical capacity were rapidly deployed within nine days of the Nepal earthquake of 25th April 2015, to provide spatiotemporally detailed estimates of population displacements from call detail records based on movements of 12 million de-identified mobile phones users. Analysis shows the evolution of population mobility patterns after the earthquake and the patterns of return to affected areas, at a high level of detail. Particularly notable is the movement of an estimated 390,000 people above normal from the Kathmandu valley after the earthquake, with most people moving to surrounding areas and the highly-populated areas in the central southern area of Nepal. This analysis provides an unprecedented level of information about human movement after a natural disaster, provided within a very short timeframe after the earthquake occurred. The patterns revealed using this method are almost impossible to find through other methods, and are of great interest to humanitarian agencies.

Setting: Multidrug-resistant tuberculosis (MDR-TB, defined as resistance to isoniazid and rifampicin) is poorly detected in Nepal; one reason may be poor functioning of culture and drug susceptibility testing (CDST) services for retreatment tuberculosis (TB) patients. Objectives: To determine, among retreatment TB patients in mid-west Nepal, 1) the number of patients registered for treatment between July 2011 and July 2012; 2) the number submitting sputum specimens for CDST to the Central Reference Laboratory (CRL), Kathmandu, along with the results; and 3) the length of time for submission and receipt of specimens. Design: Retrospective cohort study involving the review of treatment and laboratory registers from the Nepalgunj TB Referral Centre and the CRL. Results: Of 431 retreatment patients, 66 (15%) submitted sputum samples, of which 63 reached the CRL. Of these, 39 (62%) were culture-positive; 13 (33%) patients had MDR-TB. The CDST results of 19 patients were received back at the TB Referral Centre. The median turnaround time from sending specimens to receipt of results at the TB Referral Centre was 119 days. Conclusion: Less than 10% of retreatment TB patients in mid-West Nepal had CDST results recorded, leading to the underdiagnosis of MDR-TB in the region. Urgent solutions are needed to rectify this problem. PMID:26423764

Revisiting the 1993 historical extreme precipitation and damaging flood event in Central Nepal

Nepal is ranked the fourth most climate-vulnerable country in the world and it is prone to different weather-related hazards including droughts, floods, and landslides [Wang et al., 2013; Gillies et al., 2013]. Although extremely vulnerable to extreme weather events, there are no extreme weather warning system established to inform public in Nepal. Nepal has witnessed frequent drought and flood events, however, the extreme precipitation that occurred on 19-20 July 1993 created a devastating flood and landslide making it the worst weather disaster in the history of Nepal. During the second week of July, Nepal and northern India experienced abnormal dry condition due to the shifting of the monsoon trough to central India. The dry weather changed to wet when monsoon trough moved northward towards foothills of the Himalayas. Around the same period, a low pressure center was located over the south-central Nepal. The surface low was supported by the mid-, upper-level shortwave and cyclonic vorticity. A meso-scale convective system created record breaking one day rainfall (540 mm) in the region. The torrential rain impacted the major hydropower reservoir, Bagmati barrage in Karmaiya and triggered many landslides and flash floods. The region had the largest hydropower (Kulekhani hydropower, 92 MW) of the country at that time and the storm event deposited extremely large amount of sediments that reduced one-fourth (4.8 million m3) of reservoir dead storage (12 million m3). The 1-in-1000 years flood damaged the newly constructed barrage and took more than 700 lives. Major highways were damaged cutting off supply of daily needed goods, including food and gas, in the capital city, Kathmandu, for more than a month. In this presentation, the meteorological conditions of the extreme event will be diagnosed and the impact of the sedimentation due to the flood on Kulekhani reservoir and hydropower generation will be discussed.

Background To identify potential environmental drivers of Japanese Encephalitis virus (JE) transmission in Nepal, we conducted an ecological study to determine the spatial association between 2005 Nepal JE incidence, and climate, agricultural, and land-cover variables at district level. Methods District-level data on JE cases were examined using Local Indicators of Spatial Association (LISA) analysis to identify spatial clusters from 2004 to 2008 and 2005 data was used to fit a spatial lag regression model with climate, agriculture and land-cover variables. Results Prior to 2006, there was a single large cluster of JE cases located in the Far-West and Mid-West terai regions of Nepal. After 2005, the distribution of JE cases in Nepal shifted with clusters found in the central hill areas. JE incidence during the 2005 epidemic had a stronger association with May mean monthly temperature and April mean monthly total precipitation compared to mean annual temperature and precipitation. A parsimonious spatial lag regression model revealed, 1) a significant negative relationship between JE incidence and April precipitation, 2) a significant positive relationship between JE incidence and percentage of irrigated land 3) a non-significant negative relationship between JE incidence and percentage of grassland cover, and 4) a unimodal non-significant relationship between JE Incidence and pig-to-human ratio. Conclusion JE cases clustered in the terai prior to 2006 where it seemed to shift to the Kathmandu region in subsequent years. The spatial pattern of JE cases during the 2005 epidemic in Nepal was significantly associated with low precipitation and the percentage of irrigated land. Despite the availability of an effective vaccine, it is still important to understand environmental drivers of JEV transmission since the enzootic cycle of JEV transmission is not likely to be totally interrupted. Understanding the spatial dynamics of JE risk factors may be useful in providing

The Lifesaving and Lifegiving Society (LALS), a street-based nongovernmental organization established in Nepal in 1991, utilizes a harm-reduction strategy to minimize the spread of HIV among injecting drug users. Community health outreach workers, many of whom are former drug addicts, work in the streets of Kathmandu, educating, counseling, and distributing bleach, sterile water, swabs, and clean needles. They demonstrate how to clean syringes and distribute condoms. LALS also provides primary health care services such as treatment for abscesses. Clients are informed about the limited drug treatment services in Nepal and are offered the option of home detoxification under LALS supervision. LALS promotes the message that drug users should be treated as victims of a disease rather than as criminals. Family involvement, fostered through home visits, is considered important to sustaining behavioral changes and family members are informed about ways of encouraging drug users to give up drug use or at least practice safe injecting techniques. Education of and networking with Narcotics Division and other police officers has been essential to LALS' success. LALS is working with the Nepali Red Cross on integrating HIV prevention into family planning programs. A current priority is to reduce dependence on funding from donor agencies and mobilize support from private businesses.

Understanding factors determining the distribution of species is a key requirement for protecting diversity in a specific area. The aim of this study was to explore the factors affecting diversity and distribution of species of birds on different forested hills in central Nepal. The area is rich in species of birds. Because the area is characterized by steep gradients, we were also interested in the importance of altitude in determining the diversity and species composition of the bird communities. We assessed bird diversity and species composition based on point observations along a gradient of increasing altitude in two valleys (Kathmandu and Palung) in central Nepal. Data on environmental variables were also collected in order to identify the main determinants of bird diversity and species composition of the bird communities. We recorded 6522 individual birds belonging to 146 species, 77 genera and 23 families. Resident birds made up 80% (117 species) of the total dataset. The study supported the original expectation that altitude is a major determinant of species richness and composition of bird communities in the area. More diverse bird communities were found also in areas with steeper slopes. This together with the positive effect of greater heterogeneity suggests that forests on steep slopes intermixed with patches of open habitats on shallow soil at large spatial scales are more important for diverse bird communities than more disturbed habitats on shallow slopes. In addition, we demonstrated that while different habitat characteristics such as presence of forests edges and shrubs play an important role in driving species composition, but they do not affect species richness. This indicates that while habitat conditions are important determinants of the distribution of specific species, the number of niches is determined by large scale characteristics, such as landscape level habitat heterogeneity and altitude. Thus, to protect bird diversity in the mid

Per United Nations' Sustainable Development Goals, Nepal is aspiring to achieve universal and equitable access to safe and affordable drinking water and provide access to adequate and equitable sanitation for all by 2030. For these goals to be accomplished, it is important to understand the country's geographical heterogeneity and inequality of access to its drinking-water supply and sanitation (WSS) so that resource allocation and disease control can be optimized. We aimed 1) to estimate spatial heterogeneity of access to improved WSS among the overall Nepalese population at a high resolution; 2) to explore inequality within and between relevant Nepalese administrative levels; and 3) to identify the specific administrative areas in greatest need of policy attention. We extracted cluster-sample data on the use of the water supply and sanitation that included 10,826 surveyed households from the 2011 Nepal Demographic and Health Survey, then used a Gaussian kernel density estimation with adaptive bandwidths to estimate the distribution of access to improved WSS conditions over a grid at 1 × 1 km. The Gini coefficient was calculated for the measurement of inequality in the distribution of improved WSS; the Theil L measure and Theil T index were applied to account for the decomposition of inequality. 57% of Nepalese had access to improved sanitation (range: 18.1% in Mahottari to 100% in Kathmandu) and 92% to drinking-water (range: 41.7% in Doti to 100% in Bara). The most unequal districts in Gini coefficient among improved sanitation were Saptari, Sindhuli, Banke, Bajura and Achham (range: 0.276 to 0.316); and Sankhuwasabha, Arghakhanchi, Gulmi, Bhojpur, Kathmandu (range: 0.110 to 0.137) among improved drinking-water. Both the Theil L and Theil T showed that within-province inequality was substantially greater than between-province inequality; while within-district inequality was less than between-district inequality. The inequality of several districts was

Sunkoshi landslide in Nepal and its possible impact in India: A remote sensing based appraisal

A devastating landslide that killed at least 156 people occurred on the right bank of Sunkoshi river at village Jure, 70 km northeast of Kathmandu in Nepal. It not only affected hydroelectric projects in the near vicinity but also had potential to flood large tracts of downstream area in Nepal and north Bihar. Timely action by Nepal Army and Indian authorities have averted a major disaster but satellite data analysis (using IRS Resourcesat-2 LISS IV, WorldView-2, RISAT-1, Radarsat-2 etc.) reveal that the site was easily identifiable on satellite image as a potential landslide zone that has been affected by landslide related mass wasting in the past. It was reactivated and intermittently slided during 2000-2012 and finally when the whole mass came down on 2nd August 2014 pushing materials up to the opposite slope, a landslide dammed lake was formed on Sunkoshi river which extended up to a distance of 2.5-3 km as observed on 5-6th August on satellite images and the volume was estimated to be around 8.26-10.5 MCM, which needs to be released safely to avert any further disaster. Attempt is made to simulate the event to assess the run out and debris thickness using process based model. Satellite observation (using IRS Resourcesat-2 LISS IV, WorldView-2, RISAT-1, Radarsat-2 etc.), aided by hydrological data obtained through telemetry immensely helped to assess the landslide dimension, lake extent, volume, discharge, water level and travel time of water in Sunkoshi river. But the question remains how to manage the large amount of debris that Sunkoshi brings to its downstream areas causing river aggradations that eventually increases the flood risk. In such situations, the most immediate landslide remedial measures are four fold: monitoring of landslide, dam and reservoir using remote sensing and hydrological observations, controlled release of water, water discharge management at Kosi barrage and mechanism/preparedness for evacuation. The Sunkoshi landslide has brought to

Dengue viral infections are known to pose a significant risk during travel to tropical regions, but it is surprising to find dengue transmission in the hilly region of Nepal, which is over 1800mtr above sea level. A 43-year-old Caucasian female traveler from France presented with fever and abdominal pain following a diarrheal illness while visiting the central hilly region of Nepal. Over the course of 9 days, she developed fever, body aches, and joint pain, with hemorrhagic manifestation. She was hospitalized in India and treated with supportive care, with daily monitoring of her platelets. An assessment by enzyme-linked immunosorbent assay showed that she was positive for dengue non-structural protein 1. Upon her return to France, dengue virus was confirmed by reverse transcriptase-polymerase chain reaction. The district where this dengue case was reported is in the hilly region of Nepal, neighboring the capital city Kathmandu. To the best of our knowledge, there has previously been no dengue cases reported from the district. This study is important because it aims to establish a potential region of dengue virus circulation not only in the tropics, but also in the subtropics as well, which in Nepal may exceed elevations of 1800mtr. This recent case report has raised alarm among concerned health personnel, researchers, and organizations that this infectious disease is now on the way to becoming established in a temperate climate.

The essential oil from the parasitic vine Cuscuta reflexa Roxb., collected from Kirtipur, Kathmandu, Nepal, was obtained by hydrodistillation and analysed by gas chromatography-mass spectrometry. From a total of 62 peaks, 61 compounds were identified in the oil, accounting for 99.6% of the oil. The majority of the essential oil was dominated by the relatively rare component cis-3-butyl-4-vinylcyclopentane (26.4%). The oil also contained substantial amounts of limonene (5.1%) and (E)-nerolidol (9.5%). Biological screening for antimicrobial activities did not show appreciable activity against either Gram-positive (Bacillus cereus and Staphylococcus aureus) or Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria. However, marginal activity against Aspergillus niger was observed (minimum inhibitory concentration = 313 μg/mL).

The Tamang of the Kathmandu Valley have an agrarian society with little demand for literacy and schooling, yet they recognize and label mental retardation. The criteria for labeling are based partially upon insufficiency of intelligence and behavioral adaptation but primarily upon speech incompetence. There is stigma attached to the label, and it has a limiting effect upon social status and role. While the Western conception of mental deficiency is not primarily contingent upon verbal ability, speech function is a consideration in the evaluation of intelligence, as is the case in other parts of the world. In fact, verbal skill is one useful referent for future cross-cultural research on mental deficiency.

Background Although endemic cholera causes significant morbidity and mortality each year in Nepal, lack of information about the causal bacterium often hinders cholera intervention and prevention. In 2012, diarrheal outbreaks affected three districts of Nepal with confirmed cases of mortality. This study was designed to understand the drug response patterns, source, and transmission of Vibrio cholerae associated with 2012 cholera outbreaks in Nepal. Methods V. cholerae (n = 28) isolated from 2012 diarrhea outbreaks {n = 22; Kathmandu (n = 12), Doti (n = 9), Bajhang (n = 1)}, and surface water (n = 6; Kathmandu) were tested for antimicrobial response. Virulence properties and DNA fingerprinting of the strains were determined by multi-locus genetic screening employing polymerase chain reaction, DNA sequencing, and pulsed-field gel electrophoresis (PFGE). Results All V. cholerae strains isolated from patients and surface water were confirmed to be toxigenic, belonging to serogroup O1, Ogawa serotype, biotype El Tor, and possessed classical biotype cholera toxin (CTX). Double-mismatch amplification mutation assay (DMAMA)-PCR revealed the V. cholerae strains to possess the B-7 allele of ctx subunit B. DNA sequencing of tcpA revealed a point mutation at amino acid position 64 (N → S) while the ctxAB promoter revealed four copies of the tandem heptamer repeat sequence 5'-TTTTGAT-3'. V. cholerae possessed all the ORFs of the Vibrio seventh pandemic island (VSP)-I but lacked the ORFs 498–511 of VSP-II. All strains were multidrug resistant with resistance to trimethoprim-sulfamethoxazole (SXT), nalidixic acid (NA), and streptomycin (S); all carried the SXT genetic element. DNA sequencing and deduced amino acid sequence of gyrA and parC of the NAR strains (n = 4) revealed point mutations at amino acid positions 83 (S → I), and 85 (S → L), respectively. Similar PFGE (NotI) pattern revealed the Nepalese V. cholerae to be clonal

As one of the causative agents of viral hepatitis, hepatitis E virus (HEV) has gained public health attention globally. HEV epidemics occur in developing countries, associated with faecal contamination of water and poor sanitation. In industrialised nations, HEV infections are associated with travel to countries endemic for HEV, however, autochthonous infections, mainly through zoonotic transmission, are increasingly being reported. HEV can also be transmitted by blood transfusion. Nepal has experienced a number of HEV outbreaks, and recent earthquakes resulted in predictions raising the risk of an HEV outbreak to very high. This study aimed to measure HEV exposure in Nepalese blood donors after large earthquakes. Samples (n = 1,845) were collected from blood donors from Kathmandu, Chitwan, Bhaktapur and Kavre. Demographic details, including age and sex along with possible risk factors associated with HEV exposure were collected via a study-specific questionnaire. Samples were tested for HEV IgM, IgG and antigen. The proportion of donors positive for HEV IgM or IgG was calculated overall, and for each of the variables studied. Chi square and regression analyses were performed to identify factors associated with HEV exposure. Of the donors residing in earthquake affected regions (Kathmandu, Bhaktapur and Kavre), 3.2% (54/1,686; 95% CI 2.7-4.0%) were HEV IgM positive and two donors were positive for HEV antigen. Overall, 41.9% (773/1,845; 95% CI 39.7-44.2%) of donors were HEV IgG positive, with regional variation observed. Higher HEV IgG and IgM prevalence was observed in donors who reported eating pork, likely an indicator of zoonotic transmission. Previous exposure to HEV in Nepalese blood donors is relatively high. Detection of recent markers of HEV infection in healthy donors suggests recent asymptomatic HEV infection and therefore transfusion-transmission in vulnerable patients is a risk in Nepal. Surprisingly, this study did not provide evidence of a large

Inequality in access to quality healthcare is a major health policy challenge in many low- and middle-income countries. This study aimed to identify the major sources of inequity in healthcare utilization using a population-based household survey from urban Nepal. A cross-sectional survey was conducted covering 9177 individuals residing in 1997 households in five municipalities of Kathmandu valley between 2011 and 2012. The concentration index was calculated and a decomposition method was used to measure inequality in healthcare utilization, along with a horizontal inequity index (HI) to estimate socioeconomic inequalities in healthcare utilization. Results showed a significant pro-rich distribution of general healthcare utilization in all service providers (Concentration Index: 0.062, P < 0.001; HI: 0.029, P < 0.05) and private service providers (Concentration Index: 0.070, P < 0.001; HI: 0.030, P < 0.05). The pro-rich distribution of probability in general healthcare utilization was attributable to inequalities in the level of household economic status (percentage contribution: 67.8%) and in the self-reported prevalence of non-communicable diseases such as hypertension (36.7%) and diabetes (14.4%). Despite the provision of free services by public healthcare providers, our analysis found no evidence of the poor making more use of public health services (Concentration Index: 0.041, P = 0.094). Interventions to reduce the household economic burden of major illnesses, coupled with improvement in the management of public health facilities, warrant further attention by policy-makers. © The Author 2016.

On April 25, 2015, the M7.8 Gorkha earthquake struck Nepal and the city of Kathmandu. The quake caused a significant humanitarian crisis and killed more than 8,000 due to widespread building damage and triggered landslides throughout the region. This was the strongest earthquake to occur in the region since the 1934 Nepal-Bihar magnitude 8.0 quake caused more than 10,000 fatalities. In the days following the earthquake, the JPL/Caltech ARIA project produced coseismic GPS and SAR displacements, fault slip models, and damage assessments from SAR coherence change that were helpful in both understanding the event and in the response efforts. The ARIA project produced InSAR observations from two new SAR missions - JAXA's ALOS-2 and ESA's Sentinel 1a. The GPS coseismic displacements showed ~1.8 meters of southward motion and ~1.3 meters of uplift in Kathmandu. InSAR images of the displacement field and fault models show that the rupture extended 135 km southeast of the epicenter. The SAR imagery also confirmed that the fault slip did not extend to the surface, though localized offsets formed due to liquefaction. The GPS and SAR analysis has continued to image the large M7.3 aftershock and postseismic deformation. The damage assessments from coherence change were used by several organizations guiding the response effort, including the NGA, the World Bank, and OFDA/USAID. We will present imaging, modeling, and damage assessment results from the recent April 25, 2015 M7.8 earthquake in Nepal, and its largest aftershock, a M7.3 event on May 12, 2015. We also discuss how these data were used for understanding the event, guiding the response, and for educational outreach.

the ground especially in the epicenter area. Similarly, liquefaction occurred in the different parts of Kathmandu valley. However, the recording in KATNP and DMG indicate that the ground motions that resulted from the quake were not strong enough to fully weaken liquefiable materials and in most cases incipient or "marginal" liquefaction was observed. Here, we will present a compilation of the different types of mass wasting that have occurred in this region and discuss their location and hazard potential for local communities.

Mishra, S K; Pant, B P; Subedi, P

2016-01-01

Background The worldwide prevalence of diabetic retinopathy (DR) was found to be 34.6%. WHO estimates that DR is responsible for 4.8% of the 37 million cases of blindness throughout the world. In a study undertaken in urban population in Nepal, M.D. Bhattarai found the prevalence of diabetes among people aged 20 years and above to be 14.6% and the prevalence among people aged 40 years and above to be 19%. Studies on DR, to our knowledge, have mostly been hospital based in Nepal. Little information is available about prevalence of DR at the community level in Nepal. Objective To investigate the prevalence of diabetic retinopathy and associated risk factors among known diabetic population of Nepal. Method A descriptive cross sectional study was conducted among individuals aged 30 and more using cluster sampling method. The study sites were Kathmandu metropolitan city and Birgunj sub-metropolitan city. A sample size of 5400 was calculated assuming 5% prevalence rate with 95% confidence level, 5% worst acceptable level and 1.5 cluster sampling design effect. Study participants were interviewed, anthropometric measurements and fundus photograph was taken from participants with diabetes. Fundus photographs were used to grade retinopathy. Result Around 12% of the respondents were diabetic, mean age 55.43±11.86 years, of which slightly more than half were females (50.2%). Among these diabetic respondents 9.9% had some forms of diabetic retinopathy, mean age 54.08±10.34 years, 56.7% were male. When severe grade of retinopathy in any eye was considered as overall grade of retinopathy for the individual, prevalence of Non-proliferative Diabetic Retinopathy, Proliferative Diabetic Retinopathy and complete vision loss was found to be 9.1%, 0.5% and 0.3%. Prevalence of Diabetic Macular Edema was 5.5%. Duration of diabetes, family history of diabetes and blood pressure at the day of survey was found to be associated with having any retinopathy. Conclusion Diabetic retinopathy

Objective To determine, in one low income country (Nepal), which characteristics of medical students are associated with graduate doctors staying to practise in the country or in its rural areas. Design Observational cohort study. Setting Medical college registry, with internet, phone, and personal follow-up of graduates. Participants 710 graduate doctors from the first 22 classes (1983-2004) of Nepal’s first medical college, the Institute of Medicine. Main outcome measures Career practice location (foreign or in Nepal; in or outside of the capital city Kathmandu) compared with certain pre-graduation characteristics of medical student. Results 710 (97.7%) of the 727 graduates were located: 193 (27.2%) were working in Nepal in districts outside the capital city Kathmandu, 261 (36.8%) were working in Kathmandu, and 256 (36.1%) were working in foreign countries. Of 256 working abroad, 188 (73%) were in the United States. Students from later graduating classes were more likely to be working in foreign countries. Those with pre-medical education as paramedics were twice as likely to be working in Nepal and 3.5 times as likely to be in rural Nepal, compared with students with a college science background. Students who were academically in the lower third of their medical school class were twice as likely to be working in rural Nepal as those from the upper third. In a regression analysis adjusting for all variables, paramedical background (odds ratio 4.4, 95% confidence interval 1.7 to 11.6) was independently associated with a doctor remaining in Nepal. Rural birthplace (odds ratio 3.8, 1.3 to 11.5) and older age at matriculation (1.1, 1.0 to 1.2) were each independently associated with a doctor working in rural Nepal. Conclusions A cluster of medical students’ characteristics, including paramedical background, rural birthplace, and lower academic rank, was associated with a doctor remaining in Nepal and with working outside the capital city of Kathmandu.

Coulomb Failure Stress Accumulation in Nepal After the 2015 Mw 7.8 Gorkha Earthquake: Testing Earthquake Triggering Hypothesis and Evaluating Seismic Hazards

Xiong, N.; Niu, F.

2017-12-01

A Mw 7.8 earthquake struck Gorkha, Nepal, on April 5, 2015, resulting in more than 8000 deaths and 3.5 million homeless. The earthquake initiated 70km west of Kathmandu and propagated eastward, rupturing an area of approximately 150km by 60km in size. However, the earthquake failed to fully rupture the locked fault beneath the Himalaya, suggesting that the region south of Kathmandu and west of the current rupture are still locked and a much more powerful earthquake might occur in future. Therefore, the seismic hazard of the unruptured region is of great concern. In this study, we investigated the Coulomb failure stress (CFS) accumulation on the unruptured fault transferred by the Gorkha earthquake and some nearby historical great earthquakes. First, we calculated the co-seismic CFS changes of the Gorkha earthquake on the nodal planes of 16 large aftershocks to quantitatively examine whether they were brought closer to failure by the mainshock. It is shown that at least 12 of the 16 aftershocks were encouraged by an increase of CFS of 0.1-3 MPa. The correspondence between the distribution of off-fault aftershocks and the increased CFS pattern also validates the applicability of the earthquake triggering hypothesis in the thrust regime of Nepal. With the validation as confidence, we calculated the co-seismic CFS change on the locked region imparted by the Gorkha earthquake and historical great earthquakes. A newly proposed ramp-flat-ramp-flat fault geometry model was employed, and the source parameters of historical earthquakes were computed with the empirical scaling relationship. A broad region south of the Kathmandu and west of the current rupture were shown to be positively stressed with CFS change roughly ranging between 0.01 and 0.5 MPa. The maximum of CFS increase (>1MPa) was found in the updip segment south of the current rupture, implying a high seismic hazard. Since the locked region may be additionally stressed by the post-seismic relaxation of the lower

What fraction of the black carbon arriving on Yala Glacier in Langtang, Nepal, is from cooking fires in the houses in the valley below? What fraction is from elsewhere in rural Nepal? What fraction is from industrial and transport sources in Kathmandu? What fraction is from northern India and beyond? What fraction is from the high altitude forest fires that take place during March or April? Effectively mitigating the impacts of black carbon and other short-lived climate forcers requires detailed understanding not just of emissions and impacts, but also of the atmospheric transport pathways that connect the two. In mountainous areas of the Hindu-Kush Himalaya detailed quantitative knowledge about emissions, atmospheric processes, and impacts is still largely missing. The International Centre for Integrated Mountain Development (ICIMOD) is an intergovernmental organization covering Afghanistan, Pakistan, India, Nepal, China, Bhutan, Bangladesh, and Myanmar. ICIMOD's recently established Atmosphere Initiative not only assesses mitigation options and contributes to policy and capacity building in the region, but also works actively to promote collaboration among researchers in the region, while building up an in-house team whose research will address key questions about SLCF. In Spring 2013 ICIMOD's Atmosphere Initiative, in collaboration with the Institute for Advanced Sustainability Studies (IASS) in Potsdam, Germany, carried out the largest field campaign to date in Nepal, hosting instruments belonging to dozens of institutions around the world, at nine field site within and upwind of the Kathmandu Valley, Nepal. The dataset that has been collected gives unprecedented insights into the emissions and atmospheric processes taking place downwind of and within the largest urban agglomeration in the Himalaya region. Meanwhile, in collaboration with national partner institutions, ICIMOD is in the process of setting up one atmospheric observatory each in Bhutan and in

The processes occurring during continent-continent collision are still poorly understood. Ascertaining the seismic properties of the crust and uppermost mantle in such settings provides insight into continental rheology and geodynamics. The most active present-day continent-continent collision is that of India with Eurasia which has created the Himalayas and the Tibetan Plateau. Nepal provides an ideal laboratory for imaging the crustal processes resulting from the Indo-Eurasia collision. We build body wave models using local body wave arrivals picked at stations in Nepal deployed by the Department of Mining and Geology of Nepal. We use the tomographic inversion method of Roecker et al. [2006], the key feature of which is that the travel times are generated using a finite difference solution to the eikonal equation. The advantage of this technique is increased accuracy in the highly heterogeneous medium expected for the Himalayas. Travel times are calculated on a 3D Cartesian grid with a grid spacing of 6 km and intragrid times are estimated by trilinear interpolation. The gridded area spans a region of 80-90o longitude and 25-30o latitude. For a starting velocity model, we use IASP91. Inversion is performed using the LSQR algorithm. Since the damping parameter can have a significant effect on the final solution, we tested a range of damping parameters to fully explore its effect. Much of the seismicity is clustered to the West of Kathmandu at depths < 30 km. Small areas of strong fast wavespeeds exist in the centre of the region in the upper 30 km of the crust. At depths of 40-50 km, large areas of slow wavespeeds are present which track along the plate boundary.

Background Studies on Knowledge towards epilepsy among school teachers are very limited on developing countries especially with reference to Nepal. Level of knowledge of schoolteachers plays an important role on providing a greater educational support for epileptic child and to maintain good communication skills between epileptic and normal child. Objective Objective of this study is to assess the level of knowledge about epilepsy and its associated factors among school teachers. Method A cross sectional study was conducted from 10th June to 4th July, 2014 among 165 teachers teaching in six different schools of Kathmandu Metropolitan City. A selfadministrated questionnaire consisting of structured and multiple choice questions were designed to collect information on the teacher's socio-demographic profile and knowledge about epilepsy. A scoring system was developed for each question: each correct answer was given a score of 1, and a score of 0 for wrong answer. Total score was categorized on two categories: Good Knowledge and Poor Knowledge. Result Teacher's age did not correlate significantly with their knowledge about epilepsy but total years of teaching experiences and knowledge about epilepsy were found to be positively correlated (ρ= 0.165, p= 0.01). Academic qualification of teachers and different teaching level were associated with level of knowledge (p= 0.023, p= 0.021). Significant difference on knowledge score was found among teachers having different academic qualification (p= 0.019). Conclusion All teachers were aware about epilepsy, but their knowledge about epilepsy was not sufficient therefore, health education training program about epilepsy is needed for teachers.

It is widely accepted that the impact of natural hazards reflects not only the nature of geophysical processes but also the social conditions that prevail. The need for collaborative research to address these complex interactions between the natural and human systems is well recognised, however moving from theory to practice presents a number of significant challenges. How researchers frame problems; develop their research questions; select the methodologies to explore these questions; and privilege certain knowledges over others, can be seen to vary between physical and social science. Drawing on a case study examining the vulnerability of rural communities to landslides in the Upper Bhote Koshi Valley, Central Nepal, this paper explores how these barriers can be overcome and the benefits of undertaking interdisciplinary research within the natural hazards field. This research investigates the different framings of landslide risk and vulnerability from different stakeholder and disciplinary perspectives. Specifically, we ask: 1. Who is vulnerable to landslide hazard? 2. Why do people occupy landslide prone areas? 3. How do ‘at risk' rural communities perceive and respond to landslide hazard and risk? The findings, based on a series of participatory methodologies, challenge a number of assumptions made regarding landslide vulnerability in mountain communities. Within the Upper Bhote Koshi Valley clear transitions in settlement patterns, rural livelihoods and thus the occupation of landslide prone areas have been seen over time. For the majority of households, their decision to occupy these areas is driven by the economic and social benefits associated with the Arniko Highway which runs through the valley, linking Nepal with Tibet. Landslide vulnerability therefore emerges not just from societal marginalisation but also from situations of relative prosperity. The findings suggest that occupants of landslide prone areas have a good understanding of landslide hazard

Cholera occurs in sporadic cases and outbreaks in Nepal each year. Vibrio cholerae O1 (n = 522) isolated during 2007-2010 from diarrheal patients at 10 different hospital laboratories in Nepal were characterized. Biochemical and serologic identifications showed that all the isolates belonged to serogroup O1, El Tor biotype. Except 72 isolates of Inaba serotype isolated in the year 2007, all the remaining isolates were of Ogawa serotype. All isolates were resistant to nalidixic acid and furazolidone. Resistance to tetracycline, ciprofloxacin, erythromycin and co-trimoxazole were 21, 4, 16 and 90 % respectively. Seventy-seven of these isolates were selected for further characterization for ctxB gene and MLVA typing. Two different variants of classical type cholera toxin were observed. Ogawa strains from 2007 and 2010-Western Nepal outbreak harbored CTX-3 type cholera toxin, whereas Inaba serotypes in 2007 and the remaining Ogawa serotypes in 2008-2010 harbored CTX 3b-type toxin. MLVA analysis showed circulation of four different groups of altered V. cholerae O1 El Tor strains. Two different profiles were seen among 2007 Inaba (9, 3, 6, x, x) and Ogawa (10, 7, 6, x, x) isolates. The MLVA profile of 2008 and 2009 Ogawa isolates were similar to those of Inaba strains of 2007. Isolates from 2010 also showed three different MLVA profiles; profile 9, 3, 6, x, x in 3 isolates, 11, 7, 6, x, x among 2010 Western Nepal outbreak strains and profile 8, 3, 6, x, x among isolates from Butwal and Kathmandu.

The Nepal Ambient Monitoring and Source Testing Experiment (NAMASTE) field campaign targeted the in situ characterization of widespread and under-sampled combustion sources. In Kathmandu and the Terai, southern Nepal's flat plains, samples of fine particulate matter (PM2.5) were collected from wood and dung cooking fires (n = 22), generators (n = 2), groundwater pumps (n = 2), clamp kilns (n = 3), zig-zag kilns (n = 3), trash burning (n = 4), one heating fire, and one crop residue fire. Co-located measurements of carbon dioxide, carbon monoxide, and volatile organic compounds allowed for the application of the carbon mass balance approach to estimate emission factors for PM2.5, elemental carbon, organic carbon, and water-soluble inorganic ions. Organic matter was chemically speciated using gas chromatography - mass spectrometry for polycyclic aromatic hydrocarbons, sterols, n-alkanes, hopanes, steranes, and levoglucosan, which accounted for 2-8% of the measured organic carbon. These data were used to develop molecular-marker based profiles for use in source apportionment modeling. This study provides quantitative emission factors for particulate matter and its constituents for many important combustion sources in Nepal and South Asia.

German Nepal TB Project, National Tuberculosis Reference Laboratory, Kathmandu, Nepal. To evaluate whether transporting samples in OMNIgene®•SPUTUM (OM-S) reagent from a peripheral collection site to a central laboratory in Nepal can improve tuberculosis (TB) detection and increase the sensitivity of Xpert® MTB/RIF testing. One hundred sputum samples were split manually. Each portion was assigned to the OM-S group (OM-S added at collection, airline-couriered without cold chain, no other processing required) or the standard-of-care (SOC) group (samples airline-couriered on ice, sodium hydroxide + N-acetyl-L-cysteine processing required at the laboratory). Smear microscopy and Xpert testing were performed. Transport time was 2-13 days. Overall smear results were comparable (respectively 58% and 56% smear-negative results in the OM-S and SOC groups). The rate of smear-positive, Mycobacterium tuberculosis-positive (MTB+) sample detection was identical for both treatment groups, at 95%. More smear-negative MTB+ samples were detected in the OM-S group (17% vs. 13%, P = 0.0655). Sputum samples treated with OM-S can undergo multiday ambient-temperature transport and yield comparable smear and Xpert results to those of SOC samples. Further investigation with larger sample sizes is required to assess whether treating sputum samples with OM-S could increase the sensitivity of Xpert testing in smear-negative samples.

Abstract. Dengue virus (DENV) is expanding toward previously nonendemic areas. DENV has recently been introduced in Nepal with limited information. We report the clinical features and serotype distribution of DENV in Nepal during the 2010 outbreaks. A total of 1,215 clinical dengue cases at two major hospitals of central and western Nepal were investigated. Demographic, clinical, and laboratory parameters were recorded. Serum specimens were tested for DENV by IgM/IgG enzyme-linked immunosorbent assays (ELISAs) and reverse transcription polymerase chain reaction (RT-PCR). We confirmed DENV infection in 403 (33%) patients from 12 districts with an estimated case fatality rate of 1.5%. DENV infection was more common in adults (87%) and urban settings (74%). We detected all four serotypes but DENV-1 and -2 were mainly responsible for major outbreaks (92%). Overall, 60% of all DENV infections were secondary and 17% were severe dengue; both being more frequent among the DENV-2 infections. Rash, bleeding, abdominal pain, hepatomegaly, elevated liver enzymes, and thrombocytopenia were significantly more common in severe dengue compared with nonsevere infections. We also confirmed the expansion of dengue to hill urban areas (DENV-1 and -2), including the capital Kathmandu (altitude, 1,300 m) though > 90% cases were from southern plains. Differential clinical and laboratory features probably help in clinical decisions. Multiple serotypes circulation and elevated secondary infections pose potential risk of severe outbreaks and deaths in the future. Therefore, a country with recent dengue introduction, like Nepal, urgently requires a systematic surveillance and appropriate control measures in place to respond to any disastrous outbreaks.

In spite of legalising abortion and making safe abortion available at affordable price at accessible distance to almost everyone, unsafe abortion especially second trimester abortion is still a big health problem in Nepal. The objective of the study is to fi nd the demographic profile, reasons for seeking abortion and to see the effectiveness of Misoprostol in preparing the cervix. A prospective study was done in the two second trimester abortion trainings conducted in Maternity hospital, Kathmandu. Total 57 clients had second trimester abortion performed. Information was collected from structured questionnaire and then data was analysed. Commonest reason for seeking abortion was, multiparity (61.4%). Common reasons for second trimester abortion were, completed family size with unwanted pregnancy (61.4%), unwanted pregnancy in married (10.52%) unwanted pregnancy in unmarried (5.26%). Second trimester abortion is one of the most common procedures performed in reproductive-aged women and when performed by a skilled provider in the appropriate setting, it is one of the safest surgeries, if it is well supported by change in policy of the country and acceptability of the people.

While the 25 April 2015 MW7.8 Gorkha, Nepal, earthquake took a heavy toll in Nepal, damage and fatalities were lower than expected. There is thus an urgent need to understand ground motions from the mainshock and largest aftershock. We collected 3,831 accounts of macroseismic effects that include sufficient information to assign intensities. To assess intensities reliably, we apply EMS guidelines with an appreciation for issues associated with macroseismic effects of earthquakes in the Indian subcontinent. We as also analyze 21 available strong motion recordings. Available data are consistent with the peak ground acceleration (PGA) versus intensity relationship of Worden et al. (2012). We use this relationship to estimate peak ground acceleration (PGAEMS) from all intensities. For nearest-fault distances (RRUP<200km), PGAEMS is consistent with the Atkinson and Boore (2003) (AB03) subduction zone ground motion prediction equation (GMPE); at greater distances, instrumental PGA values are consistent with AB03, while PGAEMS is systematically higher. We use PGAEMS values within 200 km to investigate the variability of ground motions using the AB03 GMPE as a baseline. Across the near-field region, PGAEMS is higher by a factor of 2.0-2.5 towards the northern edge of the rupture compared to the near-field region nearer to the southern, up-dip edge of the rupture. Inferred de-amplification in the deepest part of the Kathmandu valley supports the conclusion that former lake-bed sediments experienced a pervasive non-linear response during the mainshock (Dixit et al., 2015). Ground motions were amplified in the southern Gangetic basin, but were relatively low in the northern basin. The overall distribution of ground motions and damage during the Gorkha earthquake thus reflects a combination of complex source, path, and site effects. We also analyze ground motions for the 12 May 2015 Dolakha aftershock, which we conclude was likely a high stress-drop event.

Objective To assess the feasibility of task shifting by estimating the accuracy at which primary-level health care workers can perform community-based third trimester ultrasound diagnosis for selected obstetric risk factors in rural Nepal. Methods Three auxiliary nurse midwives received two one-week ultrasound trainings at Tribhuvan University Teaching Hospital in Kathmandu. In our study site in rural Nepal, women who were ≥32 weeks in gestational age were enrolled and received ultrasound examinations from the auxiliary nurse midwives during home visits. Each auxiliary nurse midwife screened for non-cephalic presentation, multiple gestation, and placenta previa. All de-identified images were stored and uploaded onto an online server, where certified sonologists and sonographers reviewed the images and made their own diagnoses for the three conditions. Accuracy of auxiliary nurse midwife diagnoses was then calculated. Results We enrolled 804 women in the study. Each auxiliary nurse midwife’s kappa statistic for diagnosis of non-cephalic presentation was above 0.90 compared with the sonogram reviewers. Sensitivity, specificity, positive and negative predictive values were between 90–100% for all auxiliary nurse midwives For multiple gestation, the auxiliary nurse midwives were in perfect agreement with both the sonogram reviewers and maternal postpartum self-report. Two placenta previa cases were detected, and the sonogram reviewers agreed with both. Conclusion With limited training, primary-level health care workers in rural Nepal can accurately diagnose selected third trimester obstetric risk factors using ultrasonography. PMID:27500343

On April 25th 2015, the Mw 7.8 Gorkha (Nepal) earthquake ruptured a portion of the Main Himalayan Thrust underlying Kathmandu and surrounding regions. We develop kinematic slip models of the Gorkha earthquake using both a regularized multi-time-window (MTW) approach and an unsmoothed Bayesian formulation, constrained by static and high rate GPS observations, synthetic aperture radar (SAR) offset images, interferometric SAR (InSAR), and teleseismic body wave records. These models indicate that Kathmandu is located near the updip limit of fault slip and approximately 20 km south of the centroid of fault slip. Fault slip propagated unilaterally along-strike in an ESE direction for approximately 140 km with a 60 km cross-strike extent. The deeper portions of the fault are characterized by a larger ratio of high frequency (0.03-0.2 Hz) to low frequency slip than the shallower portions. From both the MTW and Bayesian results, we can resolve depth variations in slip characteristics, with higher slip roughness, higher rupture velocity, longer rise time and higher complexity of subfault source time functions in the deeper extents of the rupture. The depth varying nature of rupture characteristics suggests that the up-dip portions are characterized by relatively continuous rupture, while the down-dip portions may be better characterized by a cascaded rupture. The rupture behavior and the tectonic setting indicate that the earthquake may have ruptured both fully seismically locked and a deeper transitional portions of the collision interface, analogous to what has been seen in major subduction zone earthquakes.

Late Quaternary glacier fluctuations in the Macha Khola valley (Gorkha Himal, Nepal) were reconstructed using relative and absolute dating techniques. Our results indicate that younger moraine complexes were left by Late Holocene (<1.7 cal. ka BP), mid-Holocene (ca 3 cal. ka BP), and Lateglacial (ca 13 cal. ka BP) ice advances. Older Late Quaternary glacier advances occurred during Marine Oxygen Isotope Stages (MIS) 2 and 3-4. No relics of Middle or Early Pleistocene glaciations could be found. During MIS 3-4, glaciers advanced down to an altitude of at least 2150 m a.s.l., corresponding to an ELA depression of approximately 1300 m. At about 3500 m a.s.l., the MIS 2 Macha Khola glacier reached almost the thickness of the former MIS 3-4 glacier and retreated some time before 17.9 cal. ka BP. The Lateglacial glacier advanced again several times to altitudes between 2450 and 3400 m a.s.l. The mid-Holocene glaciers extended much farther down-valley than the Late Holocene ones. Dendrochronological data of Abies spectabilis suggested several periods of unfavourable growth conditions especially at the beginning of the 19th (1820) and 20th (1905) centuries.

Ambient air is a core media chosen for monitoring under the Stockholm Convention on POPs. While extensive monitoring of POPs in ambient air has been carried out in some parts of the globe, there are still regions with very limited information available, such as some developing countries as Nepal. This study therefore aims to target the occurrence of selected POPs in Nepal in suspected source areas/more densely populated regions. Four potential source regions in Nepal were furthermore targeted as it was hypothesized that urban areas at lower altitudes (Birgunj and Biratnagar located at approximately 86 and 80 m.a.s.l.) would be potentially more affected by OCPs because of more intensive agricultural activities in comparison to urban areas at higher altitudes (Kathmandu, Pokhara located 1400 and 1135 m.a.s.l). As some of these areas could also be impacted by LRAT, air mass back trajectories during the sampling period were additionally evaluated using HYSPLIT. The concentrations of overall POPs were twice as high in plain areas in comparison to hilly areas. DDTs and HCHs were most frequently detected in the air samples. The high p,p'-DDT/(pp'-DDE + pp'-DDD) ratio as well as the low o,p'-DDT/p,p'-DDT ratio observed in this study was inferred as continuing use of technical DDT. High levels of ∑ 26 PCBs were linked to proximity to highly urbanized and industrial areas, indicating the potential source of PCBs. The measured concentrations of legacy POPs in air from this study is assumed to represent a negligible health risk through inhalation of ambient air, however, other modes of human exposure could still be relevant in Nepal. The air mass backward trajectory analysis revealed that most of the air masses sampled originated from India and the Bay of Bengal. Copyright © 2016 Elsevier Ltd. All rights reserved.

HBV and HCV infections are widespread among the HIV-infected individuals in Nepal. The goals of this study were to investigate the epidemiological profile and risk factors for acquiring HBV and/or HCV coinfection in disadvantaged HIV-positive population groups in Nepal. We conducted a retrospective study on blood samples from HIV-positive patients from the National Public Health Laboratory at Kathmandu to assay for HBsAg, HBeAg, and anti-HCV antibodies, HIV viral load, and CD4+ T cell count. Among 579 subjects, the prevalence of HIV-HBV, HIV-HCV, and HIV-HBV-HCV coinfections was 3.62%, 2.93%, and 0.34%, respectively. Multivariate regression analysis indicated that spouses of HIV-positive migrant labourers were at significant risk for coinfection with HBV infection, and an age of >40 years in HIV-infected individuals was identified as a significant risk factor for HCV coinfection. Overall our study indicates that disadvantaged population groups such as intravenous drug users, migrant workers and their spouses, female sex workers, and men who have sex with HIV-infected men are at a high and persistent risk of acquiring viral hepatitis. We conclude that Nepalese HIV patients should receive HBV and HCV diagnostic screening on a regular basis.

Typhoid fever is a significant contributor to infectious disease mortality and morbidity in low- and middle-income countries, particularly in South Asia. With increasing antimicrobial resistance, commonly used treatments are less effective and risks increase for complications and hospitalizations. During an episode of typhoid fever, households experience multiple social and economic costs that are often undocumented. In the current study, qualitative interview data from Kathmandu and surrounding areas provide important insights into the challenges that affect those who contract typhoid fever and their caregivers, families, and communities, as well as insight into prevention and treatment options for health providers and outreach workers. When considering typhoid fever cases confirmed by blood culture, our data reveal delays in healthcare access, financial and time costs burden on households, and the need to increase health literacy. These data also illustrate the impact of limited laboratory diagnostic equipment and tools on healthcare providers' abilities to distinguish typhoid fever from other febrile conditions and treatment challenges associated with antimicrobial resistance. In light of these findings, there is an urgent need to identify and implement effective preventive measures including vaccination policies and programs focused on at-risk populations and endemic regions such as Nepal. © The Author 2017.

Abstract National legislation and global guidance address labelling of complementary foods to ensure that labels support optimal infant and young child feeding practices. This cross‐sectional study assessed the labels of commercially produced complementary foods (CPCF) sold in Phnom Penh (n = 70), Cambodia; Kathmandu Valley (n = 22), Nepal; Dakar Department (n = 84), Senegal; and Dar es Salaam (n = 26), Tanzania. Between 3.6% and 30% of products did not provide any age recommendation and 8.6−20.2% of products, from all sites, recommended an age of introduction of <6 months. Few CPCF products provided a daily ration (0.0−8.6%) and 14.5−55.6% of those that did exceeded the daily energy recommendation for complementary foods for a breastfed child from 6 to 8.9 months of age. Only 3.6−27.3% of labels provided accurate and complete messages in the required language encouraging exclusive breastfeeding, and almost none (0.0−2.9%) provided accurate and complete messages regarding the appropriate introduction of complementary foods together with continued breastfeeding. Between 34.3% and 70.2% of CPCF manufacturers also produced breastmilk substitutes and 41.7−78.0% of relevant CPCF products cross‐promoted their breastmilk substitutes products. Labelling practices of CPCF included in this study do not fully comply with international guidance on their promotion and selected aspects of national legislation, and there is a need for more detailed normative guidance on certain promotion practices in order to protect and promote optimal infant and young child feeding.

Introduction: In Bipolar disorder the mood of the patients fluctuates between depression and mania. The main objective of the study was to find out the commonest mood stabilizers used for the treatment of Bipolar affective disorders in Western Nepal in hospitalized patients in an actual clinical set up. Methods: This was a cross-sectional study which was conducted between October 2009 and September 2010 at Psychiatric ward at Manipal teaching hospital, Pokhara, Nepal, a tertiary care hospital situated in Western Nepal. The diagnosis of the disease was based on ICD-10 (Tenth revision) Classification of mental and Behavioural disorders, Diagnostic Criteria for Research. We calculated odds ratio and their 95% confidence intervals (95% CI). p< 0.05 was considered as statistically significant. Results: 62.1% of the patients were less than 40 yrs, 56.3% were male, 72.4% were unemployed and 75.9% of the patients were having monthly income <10,000/month. As far as ethnicity is concerned 37.9% of the cases were Brahmin and by occupation 29.9% of the patients were students followed by housewife 25.3%, labour 17.2%, retired 13.8% respectively. Drugs and Psychotherapy [OR 1.4, 95% (CI 0.575, 3.4017)] was prescribed in age <40 years as compared to age>40 yrs. Male patients [OR 7.22, 95% (CI 0.862, 60.499)] and [OR 2.353, 95% (CI 0.857, 6.455)] received drugs by trade names and drugs not from the national drug list of Nepal as compared to females. Monthly income <10,000/month and [OR 2.8, 95% (CI 0.742, 10.56)] tendency of receiving drugs by trade names. Among the mood elevators Sodium valproate was the commonest drug to be prescribed in 51/87(58.6%) patients followed by Lithium in 30/87 (34.5%) cases and Carbamazepine in 6/87 (6.9%) cases. Sodium valproate was prescribed at 1,000 mg/day, Lithium was prescribed at 900 mg/day in and Carbamazepine was prescribed at 800 mg/day. Conclusion: Among all the mood elevators Sodium valproate is the commonest drug prescribed for the

Salient Features of the 2015 Gorkha, Nepal Earthquake in Relation to Earthquake Cycle and Dynamic Rupture Models

Two salient features of the 2015 Gorkha, Nepal, earthquake provide new opportunities to evaluate models of earthquake cycle and dynamic rupture. The Gorkha earthquake broke only partially across the seismogenic depth of the Main Himalayan Thrust: its slip was confined in a narrow depth range near the bottom of the locked zone. As indicated by the belt of background seismicity and decades of geodetic monitoring, this is an area of stress concentration induced by deep fault creep. Previous conceptual models attribute such intermediate-size events to rheological segmentation along-dip, including a fault segment with intermediate rheology in between the stable and unstable slip segments. We will present results from earthquake cycle models that, in contrast, highlight the role of stress loading concentration, rather than frictional segmentation. These models produce "super-cycles" comprising recurrent characteristic events interspersed by deep, smaller non-characteristic events of overall increasing magnitude. Because the non-characteristic events are an intrinsic component of the earthquake super-cycle, the notion of Coulomb triggering or time-advance of the "big one" is ill-defined. The high-frequency (HF) ground motions produced in Kathmandu by the Gorkha earthquake were weaker than expected for such a magnitude and such close distance to the rupture, as attested by strong motion recordings and by macroseismic data. Static slip reached close to Kathmandu but had a long rise time, consistent with control by the along-dip extent of the rupture. Moreover, the HF (1 Hz) radiation sources, imaged by teleseismic back-projection of multiple dense arrays calibrated by aftershock data, was deep and far from Kathmandu. We argue that HF rupture imaging provided a better predictor of shaking intensity than finite source inversion. The deep location of HF radiation can be attributed to rupture over heterogeneous initial stresses left by the background seismic activity

Intestinal parasitosis is highly prevalent among the general population in Nepal. This study aimed to assess the status of intestinal parasitosis among patients attending Deukhury Community Hospital, Lamahi, Dang, situated in the mid western region of Nepal. A total of 210 stool samples examined by direct smear technique were reported. The overall prevalence of intestinal parasitic infection was found to be 21.4% (M = 23.5% vs F = 19.3%). Children < 15 yrs age were infected more often as compared to > 60 yrs and 15-60 yrs aged people. Among adults, Entamoeba histolytica infection was found to be very high compared to high helminthic infection found among children. Finding showed that, the prevalence was significantly high (68.8%) among people having low socio-economic status compared to others (31.1%) (p < 0.05). Among various parasites detected, E. histolytica was the most common parasite (48.8%) followed by helminths, mainly Ascaris lumbricoides (31.1%), hookworm (13.3%), Trichuris trichiura (4.4%) and Taenia species (2.2%) respectively in the locality.

Drawing on previous research on intimate partner violence, child maltreatment, and informal social control, we hypothesized relationships between child abuse severity and (1) protective informal social control of intimate partner violence (ISC_IPV) by neighbors, (2) intimate terrorism, (3) family order, and (4) the power of mothers in intimate relationships. In what we believe may be a first study of physical child abuse by parents in Nepal, we used a three stage cluster approach to draw a random sample of 300 families in Kathmandu. Random effects regression models were used to test the study hypotheses. The analyses found support for hypotheses one and two, but with an important caveat. Although observed (actual) protective ISC_IPV had the hypothesized negative association with child abuse severity, in one of our models perceived protective ISC_IPV was positively associated with child abuse severity. The models clarify that the overall direction of protective ISC_IPV appears to be negative (protective), but the positive finding is important to consider for both research and practice. A significant relationship between family order and child abuse severity was found, but the direction was negative rather than positive as in hypothesis three. Implications for neighborhood research and typological research on IPV and child maltreatment are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

NASA ARIA Project Maps Deformation of Earth Surface from Nepal Quake

NASA Image and Video Library

2015-05-02

NASA and its partners are contributing important observations and expertise to the ongoing response to the April 25, 2015, magnitude 7.8 Gorkha earthquake in Nepal. The quake was the strongest to occur in that area since the 1934 Nepal-Bihar magnitude 8.0 event and caused significant regional damage and a humanitarian crisis. Scientists with the Advanced Rapid Imaging and Analysis project (ARIA), a collaboration between NASA's Jet Propulsion Laboratory, Pasadena, California, and the California Institute of Technology in Pasadena, analyzed interferometric synthetic aperture radar images from the European Union's Copernicus Sentinel-1A satellite, operated by the European Space Agency and also available from the Alaska Satellite Facility (https://www.asf.alaska.edu), to calculate a map of the deformation of Earth's surface caused by the quake. This false-color map shows the amount of permanent surface movement caused almost entirely by the earthquake, as viewed by the satellite, during a 12-day interval between two Sentinel-1 images acquired on April 17 and April 29, 2015. In the map, surface displacements are seen as color contours (or "fringes"), where each color cycle represents 8 inches (20 centimeters) of surface motion. The contours show the land around Kathmandu has moved upward by more than 40 inches (1 meter). Areas without the color contours have snow or heavy vegetation that affects the radar measurements. Scientists use these maps to build detailed models of the fault and associated land movements to better understand the impact on future earthquake activity. The background image is from Google Earth. The map contains Copernicus data (2015). http://photojournal.jpl.nasa.gov/catalog/PIA19535

To investigate the impacts of the 2015 earthquakes on water quality and resources in the Gokyo Valley, drinking water samples were collected in the Khumbu region of Nepal in early 2016 and compared to baseline data from November 2012. This study was part of a larger USAID funded project housed at the National Snow and Ice Data Center to understand Contributions to High Asian Run-off from Ice and Snow (CHARIS) which has more than 10 local partners across 8 countries in High Asia. The Gokyo Valley is home to the Ngozumba Glacier and the Gokyo Lakes, which serve as the headwaters to the Dudh Koshi River. Samples were collected from tributary streams, which serve as the local drinking water sources and contribute to the Dudh Koshi watershed, along a transect from Lukla, 9181 ft, to Gokyo, 15, 557 ft. Water samples were analyzed in the field with the Aquagenx, Compartment Bag Test, a low cost method to detect E.coli, an indicator bacteria of fecal contamination. E.coli was present at the lowest elevations. Water samples were also shipped back to CU-Boulder for further chemical analysis including dissolved organic carbon (DOC), total dissolved nitrogen (TDN), arsenic, and oxygen isotopes to identify changes in hydrologic flow paths. These samples are being analyzed over the summer of 2016. Snow samples were also collected along a transect from Namche Bazaar at 11,657 ft to Gokyo Ri at 17,500 ft and have been analyzed for refractory black carbon (rBC). In general, rBC concentrations decreased with increasing elevation, except near local point-sources. Impurities like these reduce surface albedo and increase the amount of solar radiation absorbed by snow/ice, leading to enhanced melt.

A sustainable approach towards rural development: dry toilets in Nepal.

Regmi, M R

Existing inadequate sewerage systems and direct disposal of household waste into water courses has tremendously increased water pollution. Dry toilets are feasible in rural and peri-urban areas to reduce the consumption of costlier water that is required for flushing. As conventional treatment technologies require high investment, and operation and maintenance costs, dry toilets are the only suitable option left for sanitation in the 21st century when working with limited financial resources. To reduce environmental degradation and overcome this problem, the dry toilet is only the realistic option in Nepal. Two reactors, one exposed to sunrays and the other without sunrays, were constructed. In the model with sunrays, it was found that in 48 days of observation faecal coliform presence depleted to 610 cells per gm from the initial value of 7 x 10(10) and volatile organic matter came down from 98.09% to 70.18%. Similarly, in the other model, the destruction of faecal coliform in 65 days was found to be 920 cells/gm while the destruction of organic matter took 75 days. Also, observing from 313 people in a cluster on the pilot project, the annually recovered value of N, P and K was found to be 1565 kg, 125 kg, 344 kg, respectively. This paper deals with the different types of dry ecological toilet, their performance and feasibility study in Nepal, with the full involvement of local people, based on complete laboratory analysis and regular monitoring. Using dry toilets will save 14 LPCD, which is equivalent to 14 MLD and the resulting demand will become only 80 MLD for the urban area of Kathmandu. The result advocates the implementation of ecological dry toilets to save valuable water wasted in flushing, as well as saving the resources needed to treat the waste.

A comparison of observed and predicted ground motions from the 2015 MW7.8 Gorkha, Nepal, earthquake

We use 21 strong motion recordings from Nepal and India for the 25 April 2015 moment magnitude (MW) 7.8 Gorkha, Nepal, earthquake together with the extensive macroseismic intensity data set presented by Martin et al. (Seism Res Lett 87:957–962, 2015) to analyse the distribution of ground motions at near-field and regional distances. We show that the data are consistent with the instrumental peak ground acceleration (PGA) versus macroseismic intensity relationship developed by Worden et al. (Bull Seism Soc Am 102:204–221, 2012), and use this relationship to estimate peak ground acceleration from intensities (PGAEMS). For nearest-fault distances (RRUP < 200 km), PGAEMS is consistent with the Atkinson and Boore (Bull Seism Soc Am 93:1703–1729, 2003) subduction zone ground motion prediction equation (GMPE). At greater distances (RRUP > 200 km), instrumental PGA values are consistent with this GMPE, while PGAEMS is systematically higher. We suggest the latter reflects a duration effect whereby effects of weak shaking are enhanced by long-duration and/or long-period ground motions from a large event at regional distances. We use PGAEMS values within 200 km to investigate the variability of high-frequency ground motions using the Atkinson and Boore (Bull Seism Soc Am 93:1703–1729, 2003) GMPE as a baseline. Across the near-field region, PGAEMS is higher by a factor of 2.0–2.5 towards the northern, down-dip edge of the rupture compared to the near-field region nearer to the southern, up-dip edge of the rupture. Inferred deamplification in the deepest part of the Kathmandu valley supports the conclusion that former lake-bed sediments experienced a pervasive nonlinear response during the mainshock (Dixit et al. in Seismol Res Lett 86(6):1533–1539, 2015; Rajaure et al. in Tectonophysics, 2016. Ground motions were significantly amplified in the southern Gangetic basin, but were relatively low in the northern basin. The overall distribution of ground motions

Fascioliasis is a zoonotic disease caused by Fasciola species. Patient may be asymptomatic or presents with jaundice and biliary colic or right hypochondriac pain due to bile duct obstruction with gastrointestinal symptoms. We report a case of human fascioliasis in a 45 years old female presented to Tribhuvan University Teaching Hospital (TUTH), Kathmandu, Nepal on August, 2015 with fever, right hypochondriac pain, jaundice and occasional vomiting with anorexia for 4 months whose alkaline phosphatase was elevated and peripheral blood smear revealed eosinophilia. The patient also gives the history of consumption of water-cress. Endoscopic Retrograde Cholagiopancretography (ERCP) showed the presence of a flat worm resembling Fasciola hepatica and stool routine examination revealed ova of F. hepatica. The patient was treated with nitazoxanide by which she got improved. Repeat stool examination 2 weeks after treatment revealed no ova of F. hepatica. Patient with fascioliasis can be simply diagnosed with stool routine microscopy and treated with nitazoxanide. So patient with right hypochondriac pain, sign and symptoms of obstructive jaundice, eosinophilia and history of water-cress consumption should be suspected for fascioliasis and investigated and treated accordingly.

Both the number of cases of dengue fever and the areas of outbreaks within Nepal have increased significantly in recent years. Further expansion and range shift is expected in the future due to global climate change and other associated factors. However, due to limited spatially-explicit research in Nepal, there is poor understanding about the present spatial distribution patterns of dengue risk areas and the potential range shift due to future climate change. In this context, it is crucial to assess and map dengue fever risk areas in Nepal. Here, we used reported dengue cases and a set of bioclimatic variables on the MaxEnt ecological niche modeling approach to model the climatic niche and map present and future (2050s and 2070s) climatically suitable areas under different representative concentration pathways (RCP2.6, RCP6.0 and RCP8.5). Simulation-based estimates suggest that climatically suitable areas for dengue fever are presently distributed throughout the lowland Tarai from east to west and in river valleys at lower elevations. Under the different climate change scenarios, these areas will be slightly shifted towards higher elevation with varied magnitude and spatial patterns. Population exposed to climatically suitable areas of dengue fever in Nepal is anticipated to further increase in both 2050s and 2070s on all the assumed emission scenarios. These findings could be instrumental to plan and execute the strategic interventions for controlling dengue fever in Nepal. PMID:29360797

Background. This study aimed to assess the relationship between illness perception and depressive symptoms among persons with diabetes. Method. This was an analytical cross-sectional study conducted among 379 type 2 diabetic patients from three major clinical settings of Kathmandu, Nepal. Results. The prevalence of depressive symptoms was 44.1% (95% CI: 39.1, 49.1). Females (p < 0.01), homemakers (p < 0.01), 61-70 age group (p = 0.01), those without formal education (p < 0.01), and people with lower social status (p < 0.01) had significantly higher proportion of depressive symptoms than the others. Multivariable analysis identified age (β = 0.036, p = 0.016), mode of treatment (β = 0.9, p = 0.047), no formal educational level (β = 1.959, p = 0.01), emotional representation (β = 0.214, p < 0.001), identity (β = 0.196, p < 0.001), illness coherence (β = -0.109, p = 0.007), and consequences (β = 0.093, p = 0.049) as significant predictors of depressive symptoms. Conclusion. Our study demonstrated a strong relationship between illness perception and depressive symptoms among diabetic patients. Study finding indicated that persons living with diabetes in Nepal need comprehensive diabetes education program for changing poor illness perception, which ultimately helps to prevent development of depressive symptoms.

The prevalence of Helicobacter pylori antibiotic susceptibility in the Nepalese strains is untracked. We determined the antibiotic susceptibility for H. pylori and analyzed the presence of genetic mutations associated with antibiotic resistance in Nepalese strains. This study included 146 consecutive patients who underwent gastroduodenal endoscopy in Kathmandu, Nepal. Among 42 isolated H. pylori, there was no resistance to amoxicillin and tetracycline. In contrast, similar with typical South Asian patterns; metronidazole resistance rate in Nepalese strains were extremely high (88.1 %, 37/42). Clarithromycin resistance rate in Nepalese strains were modestly high (21.4 %, 9/42). Most of metronidazole resistant strains had highly distributed rdxA and frxA mutations, but were relative coincidence without a synergistic effect to increase the minimum inhibitory concentration (MIC). Among strains with the high MIC, 63.6 % (7/11) were associated with frameshift mutation at position 18 of frxA with or without rdxA involvement. However, based on next generation sequencing data we found that one strain with the highest MIC value had a novel mutation in the form of amino acid substituted at Ala-212, Gln-382, Ile-485 of dppA and Leu-145, Thr-168, Glu-117, Val-121, Arg-221 in dapF aside from missense mutations in full-length rdxA. Mutations at Asn-87 and/or Asp-91 of the gyrA were predominantly in levofloxacin-resistant strains. The gyrB mutation had steady relationship with the gyrA 87-91 mutations. Although three (44.4 %) and two (22.2 %) of clarithromycin resistant strains had point mutation on A2143G and A2146G, we confirmed the involvement of rpl22 and infB in high MIC strains without an 23SrRNA mutation. The rates of resistance to clarithromycin, metronidazole and levofloxacin were high in Nepalese strains, indicating that these antibiotics-based triple therapies are not useful as first-line treatment in Nepal.

National legislation and global guidance address labelling of complementary foods to ensure that labels support optimal infant and young child feeding practices. This cross-sectional study assessed the labels of commercially produced complementary foods (CPCF) sold in Phnom Penh (n = 70), Cambodia; Kathmandu Valley (n = 22), Nepal; Dakar Department (n = 84), Senegal; and Dar es Salaam (n = 26), Tanzania. Between 3.6% and 30% of products did not provide any age recommendation and 8.6-20.2% of products, from all sites, recommended an age of introduction of <6 months. Few CPCF products provided a daily ration (0.0-8.6%) and 14.5-55.6% of those that did exceeded the daily energy recommendation for complementary foods for a breastfed child from 6 to 8.9 months of age. Only 3.6-27.3% of labels provided accurate and complete messages in the required language encouraging exclusive breastfeeding, and almost none (0.0-2.9%) provided accurate and complete messages regarding the appropriate introduction of complementary foods together with continued breastfeeding. Between 34.3% and 70.2% of CPCF manufacturers also produced breastmilk substitutes and 41.7-78.0% of relevant CPCF products cross-promoted their breastmilk substitutes products. Labelling practices of CPCF included in this study do not fully comply with international guidance on their promotion and selected aspects of national legislation, and there is a need for more detailed normative guidance on certain promotion practices in order to protect and promote optimal infant and young child feeding. © 2016 The Authors.

Prevalence of Helicobacter pylori infection in Nepal, a low-risk country for gastric cancer, is debatable. To our knowledge, no studies have examined H. pylori virulence factors in Nepal. We determined the prevalence of H. pylori infection by using three different tests, and the genotypes of virulence factors were determined by PCR followed by sequencing. Multilocus sequence typing was used to analyze the population structure of the Nepalese strains. The prevalence of H. pylori infection in dyspeptic patients was 38.4% (56/146), and was significantly related with source of drinking water. In total, 51 strains were isolated and all were cagA-positive. Western-type-cagA (94.1%), cagA pre-EPIYA type with no deletion (92.2%), vacA s1a (74.5%), and m1c (54.9%) were the predominant genotypes. Antral mucosal atrophy levels were significantly higher in patients infected with vacA s1 than in those infected with s2 genotypes (P = 0.03). Several Nepalese strains were H. pylori recombinants with genetic features of South Asian and East Asian genotypes. These included all East-Asian-type-cagA strains, with significantly lesser activity and inflammation in the corpus than the strains of the specific South Asian genotype (P = 0.03 and P = 0.005, respectively). Although the population structure confirmed that most Nepalese strains belonged to the hpAsia2 population, some strains shared hpEurope- and Nepalese-specific components. Nepalese patients infected with strains belonging to hpEurope showed higher inflammation in the antrum than strains from the Nepalese specific population (P = 0.05). These results support that ancestor roots of Kathmandu`s people not only connected with India alone. PMID:26226153

Swine nasal samples [n = 282] were collected from 12 randomly selected farms around Kathmandu, Nepal, from healthy animals. In addition, wild monkey (Macaca mulatta) saliva samples [n = 59] were collected near temples areas in Kathmandu using a non-invasive sampling technique. All samples were processed for MRSA using standardized selective media and conventional biochemical tests. MRSA verification was done and isolates characterized by SCCmec, multilocus sequence typing, whole genome sequencing [WGS] and antibiotic susceptibilities. Six (2.1%) swine MRSA were isolated from five of the different swine herds tested, five were ST22 type IV and one ST88 type V. Four (6.8%) macaques MRSA were isolated, with three ST22 SCCmec type IV and one ST239 type III. WGS sequencing showed that the eight ciprofloxacin resistant ST22 isolates carried gyrA mutation [S84L]. Six isolates carried the erm(C) genes, five isolates carried aacC-aphD genes and four isolates carried blaZ genes. The swine linezolid resistant ST22 did not carry any known acquired linezolid resistance genes but had a mutation in ribosomal protein L22 [A29V] and an insertion in L4 [68KG69], both previously associated with linezolid resistance. Multiple virulence factors were also identified. This is the first time MRSA ST22 SCCmec IV has been isolated from livestock or primates.

We analyze strong motion records and high-rate GPS measurements of the M 7.8 Gorkha mainshock, M 7.3 Dolakha, and two moderate aftershock events recorded at four stations on the Kathmandu basin sediments, and one on rock-outcrop. Recordings on soil from all four events show systematic amplification relative to the rock site at multiple frequencies in the 0.1–2.5 Hz frequency range, and de-amplification of higher frequencies ( >2.5–10 Hz). The soil-to-rock amplification ratios for the M 7.8 and M 7.3 events have lower amplitude and frequency peaks relative to the ratios of the two moderate events, effects that could be suggestive of nonlinear site response. Further, comparisons to ground motion prediction equations show that 1) both soil and rock mainshock recordings were severely depleted of high frequencies, and 2) the depletion at high frequencies is not present in the aftershocks. These observations indicate that the high frequency deamplification is additionally related to characteristics of the source that are not captured by simplified ground motion prediction equations, and allude to seismic hazard analysis models being revised – possibly by treating isolated high frequency radiation sources separately from long period components to capture large magnitude near-source events such as the 2015 Gorkha mainshock.

Atmospheric organochlorine pesticides and polychlorinated biphenyls in urban areas of Nepal: spatial variation, sources, temporal trends, and long-range transport potential

The study of persistent organic pollutants (POPs) in low-latitude tropical and subtropical urban cities is necessary to assess their local and global impacts on ecosystems and human health. Despite studies on levels of POPs in water, soils, and sediments, analysis of the distribution patterns, seasonality, and sources of POPs in urban regions of Nepal remain limited. Polyurethane foam (PUF)-based passive air samplers were deployed in three major cities in Nepal: Kathmandu (the capital city), Pokhara, and Hetauda (agricultural cities). Dichlorodiphenyltrichloroethane (DDT) and hexachlorocyclohexane (HCH) were the dominant organochlorine pesticides in the atmosphere at all sites. The average concentrations of POPs were ∑ DDTs, 8.7-1.0 × 103 pg m-3; ∑ HCHs, 5.3-3.3 × 103 pg m-3; HCB, 5.8-3.4 × 102 pg m-3; ∑ endosulfan, BDL-51 pg m-3; and ∑ 6PCBs, 1.4-47 pg m-3. Isomer and metabolite ratio analyses suggested that the concentrations present were from both new and historical applications of the POPs. Vegetable production sites and their market places appeared to be the major DDT and HCH source areas. Higher atmospheric concentrations of DDT and HCH occurred during the pre-monsoon and monsoon seasons, and winter, respectively, closely associated with their local application for soil preparation and vegetable spraying. The estimated travel distances of the POPs (HCB, α-HCH, γ-HCH, and p, p'-DDT) under the Nepalese tropical climate were all above 1000 km, suggesting that high precipitation levels in the tropical climate were not enough to scavenge the POPs and that Nepal could be an important source region for POPs. Due to their close proximity and cold trapping (driven by low temperatures), the high Himalayas and the Tibetan Plateau are likely the key receptors of POPs emitted in Nepal. These results add to the information available on POPs from tropical developing

High altitude Himalayan regions are geo-dynamically very active and very sensitive to natural and anthropogenic disturbances due to their steep slopes, variations of precipitations with elevation and short growing periods. Nonetheless, even in this remote region human pressure is often the most important factor affecting forest landscape. In the last decades the firewood demand has increased each year between September to December. The increase in the number of tourists, mountaineering, guides, porters, carpenters, lodges lead to a peak in the use of fuelwood. In order to understand anthropogenic impacts on forest, resources landscape and stand scale dynamics were analyzed in the Sagarmatha National Park (SNP) and its Buffer Zone in the Khumbu Valley (Nepal, Eastern Himalaya). Biological and historical data sources were employed, and a multi-scale approach was adopted to capture the influence of human activities on the distribution of tree species and forest structure. Stand structure and a range of environmental variables were sampled in 197 20x20 m square plots, and land use and anthropogenic variables were derived in a GIS environment (thematic maps and IKONOS, Landsat and Terra ASTER satellite images). We used multivariate statistical analyses to relate forest structure, anthropogenic influences, land uses, and topography. Fuel wood is the prime source of energy for cooking (1480-1880 Kg/person/year) and Quercus semecarpifolia, Rhododendron arboreum and Pinus wallichiana, among the others, are the most exploited species. Due to lack of sufficient energy sources deforestation is becoming a problem in the area. This might be a major threat causing soil erosion, landslides and other natural hazards. Among the 25 species of trees that were found in the Buffer Zone Community Forests of SNP, Pinus wallichiana, Lyonia ovalifolia, Quercus semecarpifolia and Rhododendron arboreum are the dominant species. The total stand density ranged from 228 to 379 tree/ha and the

To review the efficacy and reliability of oxygen concentrators used over the last six years in Nepal. The apparatus used was a DeVilbiss(R) oxygen concentrator that provided O(2) for anesthesia supplemented with compressed air to drive a Penlon Manley Multivent Ventilator(R). It remains difficult to supply oxygen in cylinders to peripheral hospitals in Nepal due to lack of proper roads. We conducted a retrospective analysis of a sample of 378 cases anesthetized at the Bir Hospital and at a private hospital in Kathmandu from April through October 1999. The Bain circuit or its modification was used in adults, and Bain or Ayre's T piece in children. High flows from the oxygen concentrator used with the Bain and Ayre's T-circuits were reduced to 2 L/min, delivered through the halothane vaporizer, supplemented by room air in the modified Bain circuit. Positive pressure ventilation was provided with an Ambubag, Oxford Inflating Bellows or Penlon Manley Multivent Ventilator. Blood pressure, electrocardiogram, FiO(2) and SpO(2) were monitored in all cases. Surgery included urologic, general surgery, obstetrics and gynecological procedures, neurosurgery and closed mitral valvotomy. Age ranged from six months to 78 yr. The anesthetic time lasted from 45 min to 12 hr. The FiO(2) ranged from 0.5 to 0.6 in the Bain and Ayre's T circuits, and from 0.34 to 0.40 in the modified Bain circuit with a flow of oxygen of 2 L/min from the concentrator. With regular maintenance and servicing done locally, the oxygen concentrator can be used safely in adults and children. Use of the oxygen concentrator is a suitable alternative to oxygen cylinders in the developing world.

Analysis of hospitalization data can help elucidate the pattern of morbidity and mortality in any given area. Little data exist on critically ill children admitted to hospitals in the resource-limited nation of Nepal. We sought to characterize the profile, management, and mortality of children admitted to one PICU. Retrospective analysis. A newly established PICU in Nepal. All patients between the ages of 0 to 16 years admitted to the PICU from July 2009 to July 2010. None. In 12 months, 126 children were admitted to the PICU including 43% female patients. Sixty-three percent were under 5 years. Twenty-nine percent came from tertiary care hospitals and 38% from rural areas outside Kathmandu. Only 18% were transported by ambulance. Median distance travelled to be admitted was 30 km (interquartile range, 10-193). Highest number of admissions were in spring (40%) followed by summer (25%). Almost half were admitted for shock (45%), particularly septic shock (30%). The second commonest reason for admission was neurologic etiologies (15%). Neonatal admissions were also significant (19%). Mortality was 26% and was significantly associated with septic shock (p < 0.01), mechanical ventilation (p < 0.01), and multiple organ dysfunction (< 0.05). Almost one third of patients required mechanical ventilation; median duration was 4 days (interquartile range, 2-8). Mean length of stay in the hospital was 6.2 days (± 5.3) and median 4 (interquartile range, 2.5-9.0). Median Pediatric Risk of Mortality II score for nonsurvivors was 12 (interquartile range, 7-21), and median Pediatric Index of Mortality II for nonsurvivors was 10 (interquartile range, 3-32). Within a short time of opening, the PICU has been seeing significant numbers of critically ill children. Despite adverse conditions and limited resources, survival of 75% is similar to many units in developing nations. Sepsis was the most common reason for PICU admission and mortality.

Background: In Nepal, burn trauma causes more than 55,000 injuries each year. Burn-related mortality is high in Nepal, in part due to lack of allograft, leading to high infection rates. To address this challenge, our collaboration between Kirtipur Hospital, America Nepal Medical Foundation, Stanford University, and ReSurge International established Nepal’s first skin bank. Methods: We identified 3 major tasks to create a sustainable skin banking program: 1) identify and acquire the equipment and personnel needed to collect, process, store, and graft cadaveric skin for burn injuries; 2) develop safe donation protocols and documentation tools that remain feasible for low-resource settings; and 3) develop a long-term awareness program to educate the Nepali people on skin donation, a previously foreign concept. Results: Kirtipur Hospital acquired the necessary equipment and materials for the skin bank through a combination of local and international fundraising efforts. Existing U.S. skin banking protocols were adapted for the Nepali setting and piloted on potential patients, donors, and physicians. For the first time in the hospital’s history, patients with > 40% total body surface area burns were successfully treated with extensive allografts. Conclusions: It is feasible to create a skin bank in a country with no tradition of allograft skin use. Long-term sustainability now depends on spreading awareness and education in the Kathmandu Valley to overcome religious and cultural barriers that have hindered donor recruitment. Our low-cost and high-impact skin bank provides a model to expand this system to other hospitals both within Nepal and beyond. PMID:29263946

Service user and caregiver involvement has become an increasingly common strategy to enhance mental health outcomes, and has been incorporated in the mental healthpolicies of many developed nations. However, this practice is non-existent or fragmented in low and middle income countries (LMICs). Instances of service user and caregiver involvement have been rising slowly in a few LMICs, but are rarely described in the literature. Very little is known about the context of user and caregiver participation in mental health system strengthening processes in a low-income, disaster- and conflict-affected state such as Nepal. This study explores (a) the extent and experiences of service user and caregiver involvement in policy making, service planning, monitoring, and research in Nepal; (b) perceived barriers to such involvement; and (c) possible strategies to overcome barriers. Key Informant Interviews (n = 24) were conducted with service users and caregivers who were either affiliated to a mental health organization or receiving menta health care integrated within primary care. Purposive sampling was employed. Data collection was carried out in 2014 in Chitwan and Kathmandu districts of Nepal. Data analysis was carried out in NVivo10 using a framework approach. The involvement of service users affiliated to mental health organizations in policy development was reported to be 'tokenistic'. Involvement of caregivers was non-existent. Perceived barriers to greater involvement included lack of awareness, stigma and discrimination, poor economic conditions, the centralized health system, and lack of strong leadership and unity among user organizations. Increased focus on reducing public as well as self-stigma, improved policy frameworks and initiatives, and decentralization of care are some strategies that may facilitate service user and caregiver involvement. The study highlighted need for user and caregiver networks free from competing interests and priorities. Improved

NASA ARIA Project Provides New Look at Earth Surface Deformation from Nepal Quake

NASA and its partners are contributing important observations and expertise to the ongoing response to the April 25, 2015, magnitude 7.8 Gorkha earthquake in Nepal. The quake was the strongest to occur in that area since the 1934 Nepal-Bihar magnitude 8.0 event and caused significant regional damage and a humanitarian crisis. Scientists with the Advanced Rapid Imaging and Analysis project (ARIA), a collaboration between NASA's Jet Propulsion Laboratory, Pasadena, California, and the California Institute of Technology in Pasadena, analyzed interferometric synthetic aperture radar images from the PALSAR-2 instrument on the ALOS-2 satellite operated by the Japan Aerospace Exploration Agency (JAXA) to calculate a map of the deformation of Earth's surface caused by the quake. This false-color map shows the amount of permanent surface movement caused almost entirely by the earthquake, as viewed by the satellite, during a 70-day interval between two ALOS-2 images, acquired February 21 and May 2, 2015. In the map, surface displacements are seen as color contours (or "fringes"), where each color cycle represents 4.7 inches (11.9 centimeters) of surface motion. The contours show the land around Kathmandu has moved toward the satellite by up to 4.6 feet (1.4 meter), or 5.2 feet (1.6 meters) if we assume purely vertical motion. Areas without the color contours have snow or heavy vegetation that affects the radar measurements. Scientists use these maps to build detailed models of the fault and associated land movements to better understand the impact on future earthquake activity. The PALSAR-2 data were provided by JAXA through the Committee on Earth Observation Satellite (CEOS) in support of the response effort.

Most people in the rural areas of Nepal rely on Micro-hydro Power Plants (MHPs) for their energy sources. With around four decade experiences in design and development of MHPs, Nepalese techno-entrepreneurs have gained wider reputation in the South Asian region and the beyond. However with the lack of competences in developing Francis turbines, majority of the MHPs are equipped with either Pelton of Cross Flow turbine, even though Francis units are suitable. With the devastating earthquake of a 7.6 magnitude that struck in the Gorkha district on Saturday, 25 April 2015, about 76 km northwest of the capital city Kathmandu, and the aftershocks followed claimed more than 8000 lives. It did not leave hydropower plants either. Many big plants have been affected and hundreds of MHPs were damaged, needing short to long term rehabilitation. The preliminary assessment of the 61 affected MHPs in the 6 earthquake affected districts shows more than 50% sites are suitable for Francis turbine. Hence the strategic rehabilitation plan has been developed in the present paper for the affected plants considering issues like geographical shift, dislocation of people and also with the focus on replacing the old turbine with Francis turbine in the suitable sites. The similar strategy can also be implemented in other developing countries with such situations.

Psychotropic drugs play an important role in the treatment of mental, neurological and substance use disorders. Despite the advancement of the use of psycho-pharmaceuticals in the developed countries, the psychotropic drug production and supply chain management in low- and middle- income countries are still poorly developed. This study aims to explore the perceptions of stakeholders involved in all stages of the psychotropic drug supply chain about the need, quality, availability and effectiveness of psychotropic drugs, as well as barriers to their supply chain management. The study was conducted among 65 respondents from the Kathmandu, Chitwan and Pyuthan districts, grouped into four categories: producers, promoters and distributors (N = 22), policy makers and government actors (N = 8), service providers (N = 21) and service users/family members (N = 14). The respondents reported that psychotropic drugs, despite having side effects, are 1) needed, 2) available in major regional centers and 3) are effective for treating mental health problems. The stigma associated with mental illness, however, forces patients and family members to hide their use of psychotropic drugs. The study found that the process of psychotropic drug supply chain management is similar to other general drugs, with the exceptions of strict pre-approval process, quantity restriction (for production and import), and mandatory record keeping. Despite these regulatory provisions, respondents believed that the misuse of psychotropic drugs is widespread and companies are providing incentives to prescribers and retailers to retain their brand in the market.

The Gorkha earthquake on April 25th, 2015 was a long anticipated, low-angle thrust-faulting event on the shallow décollement between the India and Eurasia plates. We present a detailed multiple-event hypocenter relocation analysis of the Mw 7.8 Gorkha Nepal earthquake sequence, constrained by local seismic stations, and a geodetic rupture model based on InSAR and GPS data. We integrate these observations to place the Gorkha earthquake sequence into a seismotectonic context and evaluate potential earthquake hazard. Major results from this study include (1) a comprehensive catalog of calibrated hypocenters for the Gorkha earthquake sequence; (2) the Gorkha earthquake ruptured a 150 × 60 km patch of the Main Himalayan Thrust (MHT), the décollement defining the plate boundary at depth, over an area surrounding but predominantly north of the capital city of Kathmandu (3) the distribution of aftershock seismicity surrounds the mainshock maximum slip patch; (4) aftershocks occur at or below the mainshock rupture plane with depths generally increasing to the north beneath the higher Himalaya, possibly outlining a 10-15 km thick subduction channel between the overriding Eurasian and subducting Indian plates; (5) the largest Mw 7.3 aftershock and the highest concentration of aftershocks occurred to the southeast the mainshock rupture, on a segment of the MHT décollement that was positively stressed towards failure; (6) the near surface portion of the MHT south of Kathmandu shows no aftershocks or slip during the mainshock. Results from this study characterize the details of the Gorkha earthquake sequence and provide constraints on where earthquake hazard remains high, and thus where future, damaging earthquakes may occur in this densely populated region. Up-dip segments of the MHT should be considered to be high hazard for future damaging earthquakes.

A significant area of Himalayan glaciers tongues is covered by debris. Turbulent exchanges of sensible and latent heat at the debris surface directly act on its surface energy balance (SEB). At the same time, the large turbulent water vapour exchanges at high altitude modify the debris water content and thus its thermal properties. These must be correctly accounted for in SEB models and a proper characterisation of the atmospheric surface layer (ASL) is therefore needed. We installed an eddy-correlation system (Campbell IRGASON) during a period of 15 days over the Lirung glacier in the Langtang Valley in Nepal in the Nepal Himalaya, during the transition period between the monsoon and the dry season. We present the main characteristics of our set-up and the implication of our ASL characterisation on the parameterisation of the turbulent fluxes. During the day, moderate winds blow up-valley and the ASL is mostly unstable. Latent (sensible) heat fluxes scale between 50 and 150 (50 and 250) Wm-2 during the day, thus drying and cooling the debris and playing a significant role in the SEB. During the night, weak down-glacier winds are observed and fluxes remain weak. Spectral analysis of the turbulent data indicate that flow characteristics do not fulfil theoretical requirements needed to estimate turbulent fluxes using bulk methods and at this site our data show they would work only for the sensible heat flux evaluation.

2014-01-01

Background Public health and human right issues are challenging in low and middle income countries. The main objectives of this paper were to determine the prevalence and factors associated with domestic violence, extramarital sex, and spousal communication among male. Methods A cross-sectional study among 2466 married males in Kathmandu, Nepal was conducted using random sampling method. Adjusted odds ratios (AORs) and 95% confidence intervals (CI) of associated factors were estimated by stepwise backward likelihood ratio method. Results Prevalence of domestic violence was 63.14% (95% CI 61.20-65.05), extramarital sex was 32.12% (95% CI 30.27-34.00), and spousal communication was 48.87% (95% CI 46.85-50.90). Nearly one in five male (18.20%) had not used condom during extramarital sex. Interestingly, male who had more than three or equal children were less likely to have perpetrated domestic violence compared with those who had less children. Older male aged 25 and above were more likely (AORs = 1.55, 95% CI 1.19-2.03) to have extramarital sex compared with male aged 24 or below. Those male who had studied secondary or higher level of education were less likely to have extramarital sex compared to those who had primary level or no education. Male who had higher income were more likely to have spousal communication compared to those who had less income. Surprisingly, those male who had extramarital sex were less likely to have spousal communication compared with those was not involved in extramarital sex. Conclusion Practice of domestic violence and extramarital sex is quite common among married male in Nepal, where spousal communication is sparse. These findings can be used to advocate for immediate attention and activities needs to be endorsed by policymakers and programmers. PMID:24924872

Background Medical education is intended to prepare graduates for a promoting health and caring for the sick. Medical students are confronted with significant academic, psychological and existential stressors. There is insufficient information regarding psychological morbidity among Nepalese medical students. Objective To determine the prevalence of depression, anxiety and stress, among the medical students in Nepal, and its association with sociodemographic characteristics. Method A cross-sectional questionnaire based study was conducted including all students from first to fifth year of student using convenience method of sampling from Kathmandu University Medical School (KUSMS), Dhulikhel and Manipal College of Medical Sciences (MCOMS), Pokhara, Nepal. Depression, Anxiety and stress were assessed using Depression Anxiety and Stress Scale (DASS). Additional questions regarding demographic variables were also included in the survey. Data analysis was done on Statistical Package for the Social Sciences SPSS version 16. Result A total of 538 students participated in the study giving a response rate of 89.6%. Aamong them 56.5% were from age group 21-25 years, 42.2% were below 20 years and only 1.3% were above 25 years of age. Among them 52% were female and 48% were male. Our study found that the overall prevalence of depression was 29.9%, anxiety was 41.1% and stress was 27% among all participated medical students. Depression was significantly associated (OR 2.23, 95% CI 1.43-3.47, p<0.001) with living condition (living in hostel or rented house). Conclusion The higher level of psychiatric morbidity depression 29.9%, anxiety 41.1% and stress 27% among undergraduate medical students warrants needs for strategic plans to alleviate depression anxiety and the stressors right from the time they join medical school and has to be continued till they finish the course.

An outbreak investigation study was conducted in Pajaru, one of the initially affected Village Development Committees (VDCs) of the Jajarkot district in Nepal following an outbreak of respiratory illness in early 2015. The objectives of this study were to identify the cases and magnitude of the outbreak. A cross-sectional study was carried out in mid-April 2015 covering five most affected wards of Pajaru VDC to assess the patients using standard case definition for Influenza like Illness (ILI). Throat and nasal swabs were collected and sent to the National Influenza Center (NIC) in Kathmandu for laboratory confirmation. The throat swab samples tested at NIC found Influenza A H1N1 pdm09. The attack rate was calculated to be 3% in ward number 9 and 41% in ward number 8. Wavelength of the infection was nearly two weeks in both the wards. Nearly 54% of the specimens were positive for Influenza A H1N1 pdm09. There was no ILI case fatality in the study area. Children aged 0-15 years were most affected. Majority of the patients presented with symptoms of fever, cough and sore throat. There was gradual decline in the number of cases in all five wards suggestive of development of natural immunity in the community. True severity of the outbreak was not accurately reflected as compared to media reports.

Assessing the factors associated with sexual harassment among young female migrant workers in Nepal.

This article explores the extent of, and factors associated with, sexual harassment of young female migrant workers in the carpet and garment factories in Kathmandu Valley. Information is drawn from a survey of 550 female workers aged 14 to 19 and 12 in-depth case histories. Bivariate and multivariate techniques were applied to identify the factors associated with harassment. The survey found that 1 in 10 young women had experienced sexual harassment or coercion. Those who were exposed to pornographic movies were more likely than those with no exposure to any kind of movies to report sexual harassment. Perpetrators included coworkers, boyfriends, employers, and relatives. Case histories revealed that the inability of young women to communicate effectively with their peers and sex partners, lack of self-esteem, job insecurity, and other socioeconomic problems made them vulnerable to these abuses. The results suggest the need for advocacy and a range of factory-based interventions.

Scientific publications have become a mainstay of communication among readers, academicians, researchers and scientists worldwide. Although, its existence dates back to 17 th century in the West, Nepal is still struggling to take few steps towards improving its local science for last 50 years. Since the start of the first medical journal in 1963, the challenges remains as it were decades back regarding role of authors, peer reviewers, editors and even publishers in Nepal. Although, there has been some development in terms of the number of articles being published and appearances of the journals, yet there is a long way to go. This article analyzes the past and present scenario, and future perspective for scientific publications in Nepal.

Although it is evident that Nepal has an extremely wide range of climates within a short latitudinal distance, there is a lack of comprehensive research in this field. The climatic zoning in a topographically complex country like Nepal has important implications for the selection of scientific station network design and climate model verification, as well as for studies examining the effects of climate change in terms of shifting climatic boundaries and vegetation in highly sensitive environments. This study presents a new high-resolution climate map of Nepal on the basis of long-term (1981-2010) monthly precipitation data for 240 stations and mean air temperature data for 74 stations, using original and modified Köppen-Geiger climate classification systems. Climatic variables used in Köppen-Geiger system were calculated (i) at each station and (ii) interpolated to 1-km spatial resolution using kriging which accounted for latitude, longitude, and elevation. The original Köppen-Geiger scheme could not identify all five types of climate (including tropical) observed in Nepal. Hence, the original scheme was slightly modified by changing the boundary of coldest month mean air temperature value from 18 °C to 14.5 °C in order to delineate the realistic climatic condition of Nepal. With this modification, all five types of climate (including tropical) were identified. The most common dominant type of climate for Nepal is temperate with dry winter and hot summer (Cwa).

High-resolution Y-chromosome haplogroup analyses coupled with Y-short tandem repeat (STR) haplotypes were used to (1) investigate the genetic affinities of three populations from Nepal--including Newar, Tamang, and people from cosmopolitan Kathmandu (referred to as "Kathmandu" subsequently)--as well as a collection from Tibet and (2) evaluate whether the Himalayan mountain range represents a geographic barrier for gene flow between the Tibetan plateau and the South Asian subcontinent. The results suggest that the Tibetans and Nepalese are in part descendants of Tibeto-Burman-speaking groups originating from Northeast Asia. All four populations are represented predominantly by haplogroup O3a5-M134-derived chromosomes, whose Y-STR-based age (+/-SE) was estimated at 8.1+/-2.9 thousand years ago (KYA), more recent than its Southeast Asian counterpart. The most pronounced difference between the two regions is reflected in the opposing high-frequency distributions of haplogroups D in Tibet and R in Nepal. With the exception of Tamang, both Newar and Kathmandu exhibit considerable similarities to the Indian Y-haplogroup distribution, particularly in their haplogroup R and H composition. These results indicate gene flow from the Indian subcontinent and, in the case of haplogroup R, from Eurasia as well, a conclusion that is also supported by the admixture analysis. In contrast, whereas haplogroup D is completely absent in Nepal, it accounts for 50.6% of the Tibetan Y-chromosome gene pool. Coalescent analyses suggest that the expansion of haplogroup D derivatives--namely, D1-M15 and D3-P47 in Tibet--involved two different demographic events (5.1+/-1.8 and 11.3+/-3.7 KYA, respectively) that are more recent than those of D2-M55 representatives common in Japan. Low frequencies, relative to Nepal, of haplogroup J and R lineages in Tibet are also consistent with restricted gene flow from the subcontinent. Yet the presence of haplogroup O3a5-M134 representatives in Nepal

Nepal's demography is aging rapidly, yet few studies to date have examined how this has affected the health and well-being of the elderly, defined as those above 60 years in Nepal's Senior Citizen Act (2006). Our study, abbreviated NepEldQOLII, aims to assess perceived life satisfaction, and evaluate its relationship with nutritional health and mental well-being among the burgeoning Nepalese elderly population. A cross-sectional survey among 289 Nepalese elderly, aged ≥60 years, attending an outpatient clinic of a hospital in Kathmandu, Nepal was conducted. Nutritional status, depression, and life satisfaction were assessed by a mini-nutritional assessment scale (range: 0-14), a geriatric depression scale (range: 0-15), and a satisfaction with life scale (range: 5-35), respectively. Mediation analyses, adjusted for age, sex, marital status, and family type, were used to assess mediating relationships between nutritional and mental wellbeing with life satisfaction as the outcome. Approximately 21% of the participants were dissatisfied with their life. Life satisfaction was positively associated with being married, high family income, involvement in active earning, and a high nutritional score. Conversely, life satisfaction was inversely associated with living in a nuclear (as opposed to joint) family, the perception of having worse health than peers, the perception of being ignored/hated due to old age, and a higher depression score. In mediation analyses, both nutrition (β = 0.48, bias-corrected and accelerated (BCa) 95% CI: 0.27, 0.69) and depression (β = - 0.87, BCa 95% CI: -1.01, - 0.74) had significant direct associations with life satisfaction. Furthermore, both nutrition (β = 0.30, BCa 95% CI: 0.13, 0.49) and depression (β = - 0.07, BCa 95% CI: -0.14, - 0.03) mediate each other's association with life satisfaction. Nutritional score mediated 7% of the total association between depression and life satisfaction; depression

Color vision defect can be observed in various diseases of optic nerve and retina and also a significant number of people suffer from the inherited condition of red and green color defect. A cross-sectional descriptive study was designed with purposive sampling of students from various schools of Kathmandu Valley. All children were subjected to color vision evaluation using Ishihara Isochromatic color plates along with other examination to rule out any other causes for color deficiency. A total of 2001 students were examined, 1050 male students and 951 females with mean age of 10.35 (+/- 2.75) and 10.54 (+/- 2.72) respectively. Among the total students examined, 2.1% had some form of color vision defects. Of the male population, 3.9% had color vision defects while none of the female was found with the deficiency. The prevalence of color vision defect in Nepal is significant and comparable with the prevalence quoted in studies from different countries.

Pregnant women giving birth in Nepal need to use out-of-pocket payment for delivery care services due to a lack of insurance policies. The objective of this study was to examine the ability of pregnant Nepalese women to pay for delivery care services and the effects of the current household health expenditure on impoverishment due to hospital-based delivery services, especially normal delivery (ND) and caesarean section (CS). A cross-sectional study was conducted from May to August 2009 at Tribhuvan University Teaching Hospital. Ability to pay was defined as the current health spending being less than 5% of annual household income. Poverty occurred when a household's per capita income fell to less than US$1 per day. Impoverishment was considered as poverty headcount and normalised poverty gap. On average, the percentage of annual household income spent on current delivery care was 5.9% in the ND group and 9.7% in the CS group. The CS group had a stronger impoverishment effect resulting in a high per cent change of payment-induced poverty headcount by 78.1% and poverty gap by 97.3% compared to 7.7 and 24.1% in the ND group, respectively. There is a strong need to develop a well-prepared financial system to prevent the issue of poverty and impoverishment.

A large number of human settlements on the Nepal Himalayas are situated either on old landslide mass or on landslide-prone areas. As a result, a great number of people are affected by large- and small-scale landslides all over the Himalayas especially during monsoon periods. In Nepal, only in the half monsoon period (June 10 to August 15), 70, 50 and 68 people were killed from landslides in 2007, 2008 and 2009, respectively. In this context, this paper highlights monsoon rainfall and their implications in the Nepal Himalaya. In Nepal, monsoon is major source of rainfall in summer and approximately 80% of the annual total rainfall occurs from June to September. The measured values of mean annual precipitation in Nepal range from a low of approximately 250 mm at area north of the Himalaya to many areas exceeding 6,000 mm. The mean annual rainfall varying between 1500 mm and 2500 mm predominate over most of the country. In Nepal, the daily distribution of precipitation during rainy season is also uneven. Sometime 10% of the total annual precipitation can occur in a single day. Similarly, 50% total annual rainfall also can occur within 10 days of monsoon. This type of uneven distribution plays an important role in triggering many landslides in Nepal. When spatial distribution of landslides was evaluated from record of more than 650 landslides, it is found that more landslides events were concentrated at central Nepal in the area of high mean annual rainfall. When monsoon rainfall and landslide relationship was taken into consideration, it was noticed that a considerable number of landslides were triggered in the Himalaya by continuous rainfall of 3 to 90 days. It has been noticed that continuous rainfall of few days (5 days or 7 days or 10 days) are usually responsible for landsliding in the Nepal Himalaya. Monsoon rains usually fall with interruptions of 2-3 days and are generally characterized by low intensity and long duration. Thus, there is a strong role of

Only few individuals with alcohol problems seek help; those who do have not been described adequately. Here, we summarize the demographic and alcohol-related features of inpatients attending professional alcohol services in Nepal and examine differences between patients with and without social taboos about drinking. Fully structured interviews including the Composite International Diagnostic Interview and the Alcohol Use Disorder Identification Test were administered to 177 men and 21 women consecutively admitted to eight alcohol treatment centres in Kathmandu. Altogether, 164 patients (83%) had alcohol dependence and 24 patients (12%) had alcohol abuse. The sample had a mean age of 35.3 years (SD 10.1) with a time lag of 16.8 years (SD 9.8) from start of habitual drinking to first entry into treatment. Most (62%) were married, lived in urban areas (72%), had above-average income (57%), received adequate social support (71%), and belonged to social groups in which drinking is taboo (57%). Individuals in non-taboo group more often lived in urban areas, had lower socioeconomic status, more often reported parental problem drinking and started drinking at a younger age, whereas individuals in the taboo group more often had late onset, risky drinking, and waited longer before seeking treatment (P<0.05). Traditionally alcohol non-using castes and people with higher socioeconomic status over-represent professional alcohol services in Kathmandu. This, and high levels of hazardous and harmful alcohol use, indicate changing trends concerning social tolerance towards alcohol in Nepalese society in recent times and a heavy burden associated with alcohol disorders.

Evidence on the burden of depression, internet addiction and poor sleep quality in undergraduate students from Nepal is virtually non-existent. While the interaction between sleep quality, internet addiction and depressive symptoms is frequently assessed in studies, it is not well explored if sleep quality or internet addiction statistically mediates the association between the other two variables. We enrolled 984 students from 27 undergraduate campuses of Chitwan and Kathmandu, Nepal. We assessed sleep quality, internet addiction and depressive symptoms in these students using Pittsburgh Sleep Quality Index, Young's Internet Addiction Test and Patient Health Questionnaire-9 respectively. We included responses from 937 students in the data analysis after removing questionnaires with five percent or more fields missing. Via bootstrap approach, we assessed the mediating role of internet addiction in the association between sleep quality and depressive symptoms, and that of sleep quality in the association between internet addiction and depressive symptoms. Overall, 35.4%, 35.4% and 21.2% of students scored above validated cutoff scores for poor sleep quality, internet addiction and depression respectively. Poorer sleep quality was associated with having lower age, not being alcohol user, being a Hindu, being sexually active and having failed in previous year's board examination. Higher internet addiction was associated with having lower age, being sexually inactive and having failed in previous year's board examination. Depressive symptoms were higher for students having higher age, being sexually inactive, having failed in previous year's board examination and lower years of study. Internet addiction statistically mediated 16.5% of the indirect effect of sleep quality on depressive symptoms. Sleep quality, on the other hand, statistically mediated 30.9% of the indirect effect of internet addiction on depressive symptoms. In the current study, a great proportion of

Pilot study to reduce emissions, improve health, and offset BC emissions through the distribution of improved cook stoves in Nepal

In most developing countries, wood and other biomass fuels are still the primary source of energy for the majority of the people, particularly the poor. It is estimated that cook stoves account for approximately 20% of global black carbon emissions. In Nepal 87% of energy is supplied from traditional biomass and 75% of households still depend on biomass as a cooking fuel. The substitution of traditional cook stoves with improved cook stoves provides an important way to reduce black carbon emissions. In 2013 the International Centre for Integrated Mountain Development (ICIMOD) has commenced a pilot study that both examines ways to effectively disseminate improved cookstoves across remote rural mountain regions, and also quantifies the resulting changes in emissions, air quality and health. The selected study area is in Bajrabarahi Village in Makawanpur district, to the southwest of Kathmandu. The study area consists of around 1600 households, which are divided into control groups and groups where the cook stove intervention is taking place. The study complements the ';Clean Cooking energy solution for all by 2017' announced by the Government of Nepal recently, and will provide insights to the government on ways to effectively reduce black carbon emissions from cook stoves. To make the study robust and sustainable, local women's group and a local medical institution are involved in the project right from the conceptualization stage. The study region has been chosen in part because the medical school Patan Academy of Health Sciences (PAHS) has already started a long term health assessment in the region, and has built up considerable local contacts. The local women's group is working on the modality of cook stove distribution through micro credit programmes in the village. We will distribute the best available manufactured, fan-assisted cook stoves that are expected to reduce BC emissions the most. Health assessments, emissions estimates, as well as measurements of

On 25 April 2015, a magnitude 7.8 earthquake struck Nepal. Subsequently many large aftershocks shook the region, including one of magnitude 7.3. Much damage and over 4300 landslides were triggered. The landslides were mapped by a volunteer group who self organized to undertake an emergency response to the earthquake disaster. The number of landslides is fewer than expected based on total released seismic energy. This may be because of lack of a surface rupture and possibly also because of high surface-wave attenuation due to rugged surface topography or to the geological and geophysical characteristics of the upper crust. The observed landslides were primarily in the southern half of the Himalaya in areas where the steepest slopes occur and where peak ground accelerations were relatively high. The landslides are also concentrated on the tectonically downdropped block. However, the distribution is complex and varies dramatically from valley to valley. Furthermore, different types of landslides are concentrated in different geologic materials, which suggests local factors control the valley-scale attenuation or amplification of seismic waves or the way wave disturbances couple to the local geologic materials. Across the earthquake-affected zone on the regional scale, wave attenuation and also net downdrop and uplift may also explain as much about the distribution of landslides as slopes and distance from large slips on the fault. We will offer the regional distribution results and some specific case studies to illustrate a set of possible controlling factors.

Fault- and Area-Based PSHA in Nepal using OpenQuake: New Insights from the 2015 M7.8 Gorkha-Nepal Earthquake

Stevens, Victoria

2017-04-01

The 2015 Gorkha-Nepal M7.8 earthquake (hereafter known simply as the Gorkha earthquake) highlights the seismic risk in Nepal, allows better characterization of the geometry of the Main Himalayan Thrust (MHT), and enables comparison of recorded ground-motions with predicted ground-motions. These new data, together with recent paleoseismic studies and geodetic-based coupling models, allow for good parameterization of the fault characteristics. Other faults in Nepal remain less well studied. Unlike previous PSHA studies in Nepal that are exclusively area-based, we use a mix of faults and areas to describe six seismic sources in Nepal. For each source, the Gutenberg-Richter a and b values are found, and the maximum magnitude earthquake estimated, using a combination of earthquake catalogs, moment conservation principals and similarities to other tectonic regions. The MHT and Karakoram fault are described as fault sources, whereas four other sources - normal faulting in N-S trending grabens of northern Nepal, strike-slip faulting in both eastern and western Nepal, and background seismicity - are described as area sources. We use OpenQuake (http://openquake.org/) to carry out the analysis, and peak ground acceleration (PGA) at 2 and 10% chance in 50 years is found for Nepal, along with hazard curves at various locations. We compare this PSHA model with previous area-based models of Nepal. The Main Himalayan Thrust is the principal seismic hazard in Nepal so we study the effects of changing several parameters associated with this fault. We compare ground shaking predicted from various fault geometries suggested from the Gorkha earthquake with each other, and with a simple model of a flat fault. We also show the results from incorporating a coupling model based on geodetic data and microseismicity, which limits the down-dip extent of rupture. There have been no ground-motion prediction equations (GMPEs) developed specifically for Nepal, so we compare the results of

This study investigated the correlation between knowledge, attitude and practices on HIV and AIDS in the context of Nepal.The study was conducted among the 404 respondents; selected from the transport workers, garment factory workers, brick factory workers and health workers. It was non-experimental cross sectional study based on descriptive as well as correlational research design. Simple random technique was used to select the respondents. Survey was conducted to collect the primary data and r value was used to analyze the correlation between variables. Finding shows that 391 (96.8%) respondents have heard about HIV and AIDS; among them 388 (95.8%) respondents were mentioned that they had knowledge of way of HIV transmission also. Total 50 out of 171 unmarried (29.2%) respondents had pre-marital sexual experience. It was found that only 71 (25.6%) respondents had used the condom during their first time sexual intercourse.There was significant association (p=.000) found between the knowledge on way of HIV transmission and occupation of respondents, similarly relationship found (r = .815, p = .000 (2-tailed) between marriage age and age of first time sexual intercourseof respondents. But there was no relationship (r = .097 and p =.106 (2-tailed) found between Knowledge on way of HIV transmission and sex with non-regular sex partners. Data showed that safer sex practices was low than the level of knowledge. The educational status of respondents shows the positive association with attitude towards the necessary to have knowledge of HIV and AIDS.

Explaining Religious Differentials in Family Size Preferences: Evidence from Nepal in 1996

2015-01-01

This paper presents an examination of how religio-ethnic identity, individual religiosity, and family members’ religiosity are related to preferred family size in Nepal. Analyses of survey data from the Chitwan Valley Family Study show that socioeconomic characteristics and individual experiences can suppress, as well as largely account for, religio-ethnic differences in fertility preferences. These religio-ethnic differentials are associated with variance in particularized religious theologies or general value orientations (like son preference) across groups. In addition, individual and family religiosity are both positively associated with preferred family size, seemingly because of their association with religious beliefs that are likely to shape fertility strategies. These findings suggest improvements in how we conceptualize and empirically measure supra-individual religious influence in a variety of settings and for a range of demographically interesting outcomes.

On August 2nd 2014, a huge rockslide of approximately 5 million m3 blocked the Sun-Koshi River upstream of Jure village (Northeast of Kathmandu, Nepal). This landslide killed approximately 155 people, destroying approximately 120 houses completely and 37 partially. The main road leading to China was cut and the Sun-Koshi hydropower plant was affected. The landslide dammed the river, creating a 2 km long lake. During the whole month of August the authorities and the army managed to drain the lake in order to avoid a potential dam collapse and a disaster by flooding downstream. In addition, a road was built very quickly in the opposite slope of the rockslide. The main road was reopened in November 2014 crossing the rock avalanche deposit to reach China border. Rocky steep slope on right bank of lake is used for earthen road construction. After the quick draining of the lake water on October 5, 2014, many landslides were induced or reactivated on the slopes along the lake shore. Some are affecting the slopes over several hundred in uphill section. However, the roads are also promoting shallow landslides or old landslides reactivation. The DEM extracted from merging 16 terrestrial laser scanner (TLS) acquisitions permits to analyse the rock fall avalanche volume, scar structure and deposits. The rockslide was developed in phyllites, quartzite and sandstones. The stratification is folded but mainly subhorizontal in the scar area, while the scar is defined by several faults and visible joint sets. Using TLS and SRTM data the volume of the rockslide can be approximated at 5 million m3. From TLS data it is also possible to identify regional faults, which form the back scar with a dip of approximately 165°/60°. The discontinuity sets ~250°/60° and 075°/45° are forming oblique shallow wedges. In addition, subvertical joints which are cutting the whole scar are oriented north 145°. All these structures permits to define the volume involved in the rockslide. Satellite

Astronomy and space science education had been given least importance by Nepalese government in the past. The modern astronomy movement is believed to have started when an official observation programme of Haley's comet was organized by Royal Nepal Academy of Science and Technology (RONAST) in 1986. Following the huge pressure from the scientific community, the Nepal government (Kingdom of Nepal at that time) established B.P. Koirala Memorial Planetarium, Observatory and Science Museum Development Board in 1992. Initiatives of the project started with observatory set up and the development of astrophysics syllabus for university students. Astrophysics is included as an elective paper in the Physics masters course. The lead astrophysicist of Nepal Dr. Binil Aryal is running a research group in Tribhuvan University since 2005 which has a significant number of international publications. The developing government initiatives and achievements will be discussed. In 2007, a group of astronomy enthusiastic students along with amateurs working independently in past established Nepal Astronomical Society (NASO), which surprisingly increased the amateur activities and inspired other amateur groups to revive. During IYA 2009, more than 80 outreach and observation events were organized solely by NASO. NASO was able to collaborate with many international programmes and projects like GHOU/GTTP, EurAstro, AWB, UNAWE, SGAC, Star Peace, TWAN etc during and beyond IYA2009. Currently Nepal is recognized as the most eventful country of outreach and astronomy education among the amateur community. The success story of the astronomy movement and the local difficulties while organizing the events will be explained.

Recently, CTX-M-type extended-spectrum-β-lactamase (ESBL)-producing Escherichia coli strains have emerged worldwide. In particular, E. coli with O antigen type 25 (O25) and sequence type 131 (ST131), which is often associated with the CTX-M-15 ESBL, has been increasingly reported globally; however, epidemiology reports on ESBL-producing E. coli in Asia are limited. Patients with clinical isolates of ESBL-producing E. coli in the Tribhuvan University teaching hospital in Kathmandu, Nepal, were included in this study. Whole-genome sequencing of the isolates was conducted to analyze multilocus sequence types, phylotypes, virulence genotypes, O25b-ST131 clones, and distribution of acquired drug resistance genes. During the study period, 105 patients with ESBL-producing E. coli isolation were identified, and the majority (90%) of these isolates were CTX-M-15 positive. The most dominant ST was ST131 (n = 54; 51.4%), followed by ST648 (n = 15; 14.3%). All ST131 isolates were identified as O25b-ST131 clones, subclone H30-Rx. Three ST groups (ST131, ST648, and non-ST131/648) were compared in further analyses. ST648 isolates had a proportionally higher resistance to non-β-lactam antibiotics and featured drug-resistant genes more frequently than ST131 or non-ST131/648 isolates. ST131 possessed the most virulence genes, followed by ST648. The clinical characteristics were similar among groups. More than 38% of ESBL-producing E. coli isolates were from the outpatient clinic, and pregnant patients comprised 24% of ESBL-producing E. coli cases. We revealed that the high resistance of ESBL-producing E. coli to multiple classes of antibiotics in Nepal is driven mainly by CTX-M-producing ST131 and ST648. Their immense prevalence in the communities is a matter of great concern. PMID:25824221

Two large earthquakes in 2015 caused widespread destruction in Nepal. This study aimed to examine frequency of common mental health and psychosocial problems and their correlates following the earthquakes. A stratified multi-stage cluster sampling design was employed to randomly select 513 participants (aged 16 and above) from three earthquake-affected districts in Nepal: Kathmandu, Gorkha and Sindhupalchowk, 4 months after the second earthquake. Outcomes were selected based on qualitative preparatory research and included symptoms of depression and anxiety (Hopkins Symptom Checklist-25); post-traumatic stress disorder (PTSD Checklist-Civilian); hazardous alcohol use (AUDIT-C); symptoms indicating severe psychological distress (WHO-UNHCR Assessment Schedule of Serious Symptoms in Humanitarian Settings (WASSS)); suicidal ideation (Composite International Diagnostic Interview); perceived needs (Humanitarian Emergency Settings Perceived Needs Scale (HESPER)); and functional impairment (locally developed scale). A substantial percentage of participants scored above validated cut-off scores for depression (34.3%, 95% CI 28.4-40.4) and anxiety (33.8%, 95% CI 27.6-40.6). Hazardous alcohol use was reported by 20.4% (95% CI 17.1-24.3) and 10.9% (95% CI 8.8-13.5) reported suicidal ideation. Forty-two percent reported that 'distress' was a serious problem in their community. Anger that was out of control (symptom from the WASSS) was reported by 33.7% (95% CI 29.5-38.2). Fewer people had elevated rates of PTSD symptoms above a validated cut-off score (5.2%, 95% CI 3.9-6.8), and levels of functional impairment were also relatively low. Correlates of elevated symptom scores were female gender, lower caste and greater number of perceived needs. Residing in Gorkha and Sindhupalchowk districts and lower caste were also associated with greater perceived needs. Higher levels of impaired functioning were associated with greater odds of depression and anxiety symptoms; impaired

Understanding Health Research Ethics in Nepal.

Unlike other countries in South Asia, in Nepal research in the health sector has a relatively recent history. Most health research activities in the country are sponsored by international collaborative assemblages of aid agencies and universities. Data from Nepal Health Research Council shows that, officially, 1,212 health research activities have been carried out between 1991 and 2014. These range from addressing immediate health problems at the country level through operational research, to evaluations and programmatic interventions that are aimed at generating evidence, to more systematic research activities that inform global scientific and policy debates. Established in 1991, the Ethical Review Board of the Nepal Health Research Council (NHRC) is the central body that has the formal regulating authority of all the health research activities in country, granted through an act of parliament. Based on research conducted between 2010 and 2013, and a workshop on research ethics that the authors conducted in July 2012 in Nepal as a part of the on-going research, this article highlights the emerging regulatory and ethical fields in this low-income country that has witnessed these increased health research activities. Issues arising reflect this particular political economy of research (what constitutes health research, where resources come from, who defines the research agenda, culture of contract research, costs of review, developing Nepal's research capacity, through to the politics of publication of data/findings) and includes questions to emerging regulatory and ethical frameworks. © 2016 The Authors Developing World Bioethics Published by John Wiley & Sons Ltd.

The Nepal Contraceptive Retail Sales (CRS) Project, 5 years after lauching product sales in June 1978, incorporated as a private, nonprofit company under Nepalese management. The transition was finalized in August 1983. The Company will work through a cooperative agreement with USAID/Kathmandu to complement the national family planning goals as the program continues to provide comtraceptives through retail channels at subsidized prices. Company objectives include: increase contraceptive sales by at least 15% per year; make CRS cost effective and move towards self sufficiency; and explore the possibility of marketing noncontraceptive health products to improve primary health care. After only5 years the program can point to some impressive successes. The number of retial shops selling family planning products increased from 100 in 1978 to over 8000, extending CRS product availability to 66 of the country's 75 districts. Retail sales have climbed dramatically in the 5-year period, from Rs 46,817 in 1978 to Rs 271,039 in 1982. Sales in terms of couple year protection CYP) have grown to 24,451 CYP(1982), a 36% increase over 1980 CYP. Since the beginning of the CRS marketing program, total distribution of contraceptives--through both CRS and the Family Planning Maternal and Child Haelth (FP/MCH) Project--has been increasing. While the FP/MCH program remains the largest distributor,contribution of CRS Products is increasing, indicating that CRS is creating new product acceptors. CRS market share in 1982 was 43% for condoms and 16% for oral contraceptives (OCs). CRS markets 5 products which are subsidized in order to be affordable to consumers as well as attractive to sellers. The initial products launched in June 1978 were Gulaf standard dose OCs and Dhaal lubricated colored condoms. A less expensive lubricates, plain Suki-Dhaal condom was introduced in June 1980 in an attempt to reach poorer rural populations, but rural distribution costs are excessive and Suki

In Asian concentrated HIV epidemics, data on coinfection of sexually transmitted infections (STIs) among HIV-positive individuals are limited. The authors measured the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhea (NG), and syphilis, and their correlates among 319 HIV-positive individuals in Kathmandu, Nepal. The authors tested blood samples for syphilis and urine samples for CT and NG. Overall, 17 (5.3%) participants had at least 1 STI (CT: 1.3%, NG: 2.8%, and syphilis: 1.2%). Of 226 participants who had sex in past 6 months, 51.3% did not always use condoms. Older (aged 35-60 years) participants were more likely (adjusted odds ratio [AOR] = 3.83; 95% confidence interval [CI] = 1.19-12.33; P = .024) and those who were currently married (AOR = 0.30; 95% CI = 0.09-0.97; P = .046) or on antiretroviral therapy (AOR = 0.21; 95% CI = 0.06-0.71; P = .012) were less likely to have at least 1 STI. Our results suggest the need to strengthen the efforts to screen and treat STIs and to promote safer sexual practices among Nepalese HIV-positive individuals.

Ground Water Resources Development Board (GWRDB), Government of Nepal, is the sole authority for systematize investigation, and management of ground water in the country. This study was conducted by GWRDB to create a data base of the groundwater potential in the hilly area. The main purpose of the study was to assess the groundwater potential at the Madi Phant Valley, Lesser Himalaya Region, Plapa District, Nepal. Data were acquired from WDJD-4 and analyzed using computer aided software called IPI2win, which yield an automatic interpretation of the apparent resistivity and data were correlated with lithologs of the vertical section. The simulated results of the ten VES points conducted using Schlumberger Configuration with AB/2 varying from 2 to 400 m and MN/2 varying from 0.5 to 50m reveal the presence of 4 to 8 geo-electric layers. Results obtained from software were rechecked by plotting the apparent resistivity value on Log-Log transparent graph sheet and manually interpreted using master curves and auxiliary curves. The resistivity values of the different layers' ranges from 3 Ωm to 3700 Ωm and were statistically analyzed from Golden Software Grapher. Representative resistivity sounding curves with modeled layer obtained after inversion was used to delineate the aquifer and 1D geoelectric sections. The geoelectrical sections for the study area consists of: the topsoil, sandy silt, sand and gravel, fractured rock and the fresh basement rock. The groundwater bearing layer of fractured rock varies between depth of 8-65 meters across foothill site (Eastern Corner) of the study area and groundwater bearing layer of sand and gravel/fractured rock varies between depth of 20-100 m in the central part of the Madi Phant valley. Contour map and 3D map of bedrock and water bearing layers for the conceptual model were prepared with the help of surfer shows that the gradient of the contour is high in the surrounding parts and flat in the center of Valley.

Kathmandu Metropolitan City has attempted to reorganize its solid waste management a number of times. The German Technical and Financial Aid Organization led early efforts that were followed by a number of more recent experiments that left the city with an unsustainable solid waste management system following the termination of foreign aid. To examine this failure, the research team evaluated household surveys, field observations, interviews, and other primary and secondary information within the context of technical, social, and institutional analyses. The survey results show that the solid waste collection rates are far below the 90% claimed by the metropolis and street sweeping consumes approximately 51% of its solid waste budget. As a result of the relatively low collection rates the city residents are encouraged to dump waste into public lands. Consequently, too much of the city's resources are focused on sweeping rather than collection. Kathmandu needs to recognize informal waste picking, privatize, use local techniques, build capacity, promote bottom-up and participatory styles of management, and regulate policies to maintain solid waste management.

Retreat of glaciers and formation of glacial lakes in Nepal Himalaya have been reported to be related with the temperature rise in the region. Glacier Lake Outburst Floods (GLOF) are the growing climate induced hazards in the Himalaya. GLOF has increased the vulnerability of community and fragile ecosystem in the mountain valleys. This study has analyzed the potential impacts from GLOF in the highland of eastern Nepal and the potential role of Information Communication Technologies (ICT) to cope with such impacts. I analyzed the trend of climatic pattern (temperature and precipitation) of the Eastern Himalaya Region of Nepal available from the Department of Hydrology and Meteorology, Government of Nepal, and prepared the latest location map of the glacial lakes using google earth and ArcGIS applications in the highland of the Kanchanjungha Conservation Area of the region. Tiptala glacial lake, located at an elevation of 4950 m, within the conservation area, was selected for the GLOF hazard assessment. I used semi-structured questionnaire survey and key informants' interviews in the community in order to assess the potential hazard of GLOF. With the varying sizes, 46 glacial lakes were located in the region, which covers over 2.57 sq. km in total. Though the larger portion of the downstream area of the Tiptala glacial lake fall in the remote location away from major residential area, few villages, major pasture lands for Yaks, foot trails, and several bridges across the Tamor River below the lake are in risk of GLOF. Poor access due to extreme geographical remoteness and capacity to afford the modern technologies in the community are the major limiting factor to the knowledge and information about the climate change and related impacts. Modern ICTs has high potential to reduce the risk of climate related hazards in the remote area by information dissemination and awareness.

We determine whether age is a prognostic factor for surgical outcomes of external dacryocystorhinostomy (Ex-DCR). This retrospective cohort study conducted at Tilganga Institute of Ophthalmology (Kathmandu, Nepal) compared pediatric Ex-DCR procedures (age ≤ 15 years) to adult Ex-DCR procedures (age > 15 years) and was performed between January 2013 and December 2013, with a minimum follow-up period of 6 months. Primary outcome measure was rate of success, defined as complete resolution of subjective symptom(s) of epiphora (subjective success), combined with patent lacrimal passage on syringing (anatomical success) at last follow-up visit. Other outcome measures included clinical presentation, diagnosis, intraoperative complications and post-operative complications. In total, 154 Ex-DCR procedures were included, with an age range of 8 months to 81 years (mean age 36.4 ± 21.0 years). In all, 38 pediatric Ex-DCR procedures were compared to 116 adult procedures. Success rates were 97% in the pediatric group and 95% in the adult group, with no clinically or statistically significant difference in success rate or complication rate between groups (p > 0.05). Our study yielded high success rates of Ex-DCR in both pediatric and adult age groups suggesting that Ex-DCR remains an optimal treatment choice for all age groups. With no difference in surgical outcomes between pediatric and adult patients, including complication rate, we conclude that age is not a prognostic factor for Ex-DCR failure. We do not recommend adjuvant therapy for pediatric patients.

Post-partum depression is a common complication of women after childbirth. The objective of this study was to determine the prevalence of and factors associated with depressive symptoms among post-partum mothers attending a child immunization clinic at a maternity hospital in Kathmandu, Nepal. This cross-sectional study was conducted among 346 post-partum mothers at six to ten weeks after delivery using systematic random sampling. Mothers were interviewed using a semi-structured questionnaire. The Edinburgh Postnatal Depression Scale (EPDS) was used to screen for depressive symptoms. Logistic regression analysis was used to calculate the association of post-partum depressive symptoms with socio-demographic and maternal factors. The prevalence of post-partum depressive symptoms among mothers was 30%. Mothers aged 20 to 29 years were less likely to have depressive symptoms (adjusted odds ratio (aOR) = 0.40; 95% CI: 0.21-0.76) compared to older mothers. Similarly, mothers with a history of pregnancy-induced health problems were more likely to have depressive symptoms (aOR = 2.16; CI: 1.00-4.66) and subjective feelings of stress (aOR = 3.86; CI: 1.84-4.66) than mothers who did not. The number of post-partum mothers experiencing depressive symptoms was high; almost one-third of the participants reported having them. Pregnancy-induced health problems and subjective feelings of stress during pregnancy in the post-partum period were found to be associated with depressive symptoms among these women. Screening of depressive symptoms should be included in routine antenatal and postnatal care services for early identification and prevention.

Studies on potential emission of hazardous gases due to uncontrolled open-air burning of waste vehicle tyres and their possible impacts on the environment

Shakya, Pawan R.; Shrestha, Pratima; Tamrakar, Chirika S.; Bhattarai, Pradeep K.

Uncontrolled open-air burning of waste vehicle tyres causing environmental pollution has become a popular practice in Nepal despite official ban considering the environment and public health hazards. In this study, an experimental model was set up in a laboratory scale in an attempt to understand the potential emission of hazardous gases such as CO, SO 2 and NO 2 due to such activities in Kathmandu Valley and their possible impacts on the environment. For this purpose, four types of tyre were collected representing two from passenger car and two from motorbike category. The emission level of CO in the tyre smoke was measured with a CO gas detector tube while SO 2 and NO 2 were determined by UV-visible spectrophotometer. Among the three types of the gases analyzed, SO 2 was emitted in significantly high levels by all the representative tyre samples. The emission levels of CO, SO 2 and NO 2 ranged from 21to 49, 102to 820 and 3to 9 μg g -1, respectively. Results revealed that the emission levels also varied with the tyre types and qualities. The potential emission of the hazardous gases per representative scrap tyre mass was also estimated. Results indicate that the gaseous pollutants due to the tyre fires could make a significant contribution for deterioration of the environmental condition of the Valley or elsewhere.

Nepal, a small landlocked and one of the least developed countries in south Asia is curious with its neighbor's giant space missions. As for now, space mission is not imminent to Nepal at least for decade. Due to lack of proper education and the resources; space education is also not very effective. In the curriculum of Nepal, basic astronomy is included in the science book of middle school which consist only 5% of the total course and 10% in high school. However the total course has been mostly theoretical which has made this subject uninteresting and difficult among the students. The examinations in all education levels are practiced on the rote memorization of contents. Pokhara Astronomical Society (PAS) introduced new techniques in teaching with more practical approach. We helped students to construct bamboo telescopes and observe the night sky which brought tremendous interest in studying astronomy in middle school. Similarly in high schools we organized different kinds of webinar with renowned scientist from different parts of the world. We screened documentaries of space activities; we helped them to use online robotic telescopes by using internet. This eventually is creating more interest in students to study science and particularly astronomy in their higher studies. The use of mobile Apps and different satellite tracking website helped students determine the location of space objects and created more interest for detail study of them. We are now reaching thousands of students with different proceedings to popularize astronomy and generating interest to pursue higher education in this subject. As well as creating the scientific awareness and understanding among others who are not choosing science in their higher studies. This paper highlights the comparative study of advanced and practical approach of teaching over traditional approach. The results of survey suggest most students are interested in choosing science in their higher studies where practical

Assessment of social vulnerability to natural hazards in Nepal

This paper investigates district-wide social vulnerability to natural hazards in Nepal. Disasters such as earthquakes, floods, landslides, epidemics, and droughts are common in Nepal. Every year thousands of people are killed and huge economic and environmental losses occur in Nepal due to various natural hazards. Although natural hazards are well recognized, quantitative and qualitative social vulnerability mapping has not existed until now in Nepal. This study aims to quantify the social vulnerability on a local scale, considering all 75 districts using the available census. To perform district-level vulnerability mapping, 13 variables were selected and aggregated indexes were plotted in an ArcGIS environment. The sum of results shows that only 4 districts in Nepal have a very low social vulnerability index whereas 46 districts (61 %) are at moderate to high social vulnerability levels. Vulnerability mapping highlights the immediate need for decentralized frameworks to tackle natural hazards in district level; additionally, the results of this study can contribute to preparedness, planning and resource management, inter-district coordination, contingency planning, and public awareness efforts.

To find out the spectrum of various histopathological types of primary neoplasms of different parts/organs of the female reproductive system seen at the Kathmandu University Teaching Hospital (KUTH) as there exists a worldwide wide variation in the distribution of various neoplasms, which appears largely due to exogenous factors rather than due to inherent differences between populations. This was a retrospective study. It was carried out at KUTH. All neoplasms of the female reproductive system seen at the KUTH during the period of 20 months from 1st January 2004 to 31st August 2005 were included in this study and examined by light microscope (LM). A total number of 60 cases of neoplasms of the female reproductive system were seen. Out of these, 1 (1.7%) was of the vagina (squamous cell carcinoma, papillary variant); 16 (26.7%) were of the cervix of the uterus (all squamous cell carcinoma in advanced stage); none were of the endometrium; 20 (33.3%) were of the body of the uterus/uterine muscle (all liomyomas); 16 (26.7%) were of the ovary, (11 benign, consisting of nine mature cystic tertoma, also known as dermoid cyst, one serous papillary cystdenoma and one mucinous cystadenoma; and, five malignant, consisting of two serous cystadenocarcinoma, two mucinous cystadenocarcinoma and one mixed mucinous and serous cystadenocarcinoma); and, 7 (11.6%) were of the breast (two benign, consisting of fibroadenoma and five malignant, all consisting of infiltrating ductal carcinoma in advanced stage). There were relatively a large number of cases of advanced stage of cancer of uterine cervix. All breast cancers seen were also in advanced stage. Endometrial carcinoma was conspicuously absent in our this small series of cases.

Violence related injury is a serious public health issue all over the world. This study aims to assess the association between several socio-economic factors and intimate partner violence (IPV) in Nepal. A cross-sectional study was conducted among 236 women working in carpet and garment factories in Kathmandu, Nepal. Interviews were conducted to collect quantitative data on three forms of IPV, namely physical violence, psychological violence and sexual violence, as well as on a number of potentially associated factors. Twenty-two percent of women experienced sexual IPV, 28% physical IPV and 35% psychological IPV at least once in the last 12 months. The variables independently associated with at least one form of IPV were: age of the woman >29 years [OR = 4.23, p = 0.025 for physical IPV; OR = 6.94, p = 0.008 for sexual IPV; OR = 3.42, p = 0.043 for psychological IPV], alcohol consumption of the husband [OR = 9.97, p < 0.001 for physical IPV; OR = 3.76, p = 0.004 for sexual IPV; OR = 4.85, p < 0.001 for psychological IPV], education of the husband above primary level [OR = 0.43, p = 0.013 for physical IPV; OR = 0.51, p = 0.033 for psychological IPV], and economic dependency of the woman on the husband [OR = 3.04, p = 0.021 for physical IPV; OR = 2.97, p = 0.008 for psychological IPV]. This study identified various factors associated with IPV and showed that economic dependence of wives on their husband was among the most important ones. Thus, for the prevention of IPV against women, long term strategies aiming at livelihood and economic empowerment as well as independence of women would be suggested.

The Nepalese government and some 225 families in the private sector are engaged in an expanding aquaculture program in lakes Phewa, Begnas and Rupa in the Pokhara Valley, Nepal (Swar & Pradhan 1992). Bighead carp (Aristichthys nobilis) and silver carp (Hypopthalmichthys molitrix) are propagated in hatchery ponds and are raised to market size in mesh enclosures (having sides, tops and bottoms) suspended to a depth of 2 m. Some 300 cages are presently in use, with annual production varying from 3.4 kg/m3 Lake Phewa to about 5 kg/m3 in lakes Begnas and Rupa (Swar & Pradhan 1992). These cage-reared fish are an important source of animal protein and revenue (Swar 1981). Tourism in the region provides growers a continuous market for their fish.

Understanding effects of armed conflict on health outcomes: the case of Nepal

PubMed Central

2010-01-01

Objective There is abundance of literature on adverse effects of conflict on the health of the population. In contrast to this, sporadic data in Nepal claim improvements in most of the health indicators during the decade-long armed conflict (1996-2006). However, systematic information to support or reject this claim is scant. This study reviews Nepal's key health indicators before and after the violent conflict and explores the possible factors facilitating the progress. Methods A secondary analysis has been conducted of two demographic health surveys-Nepal Family Health Survey (NFHS) 1996 and Nepal Demographic and Health Survey (NDHS) 2006; the latter was supplemented by a study carried out by the Nepal Health Research Council in 2006. Results The data show Nepal has made progress in 16 out of 19 health indicators which are part of the Millennium Development Goals whilst three indicators have remained static. Our analysis suggests a number of conflict and non-conflict factors which may have led to this success. Conclusion The lessons learnt from Nepal could be replicable elsewhere in conflict and post-conflict environments. A nationwide large-scale empirical study is needed to further assess the determinants of Nepal's success in the health sector at a time the country experienced a decade of armed conflict.

Though the results of these endeavors are published in scientific journals, formal citation analyses have not been performed on works contributed by Nepalese vision scientists. To study Nepal's contribution to vision science literature in the database "Web of Science". The primary data source of this paper was Web of Science, a citation database of Thomas Reuters. All bibliometric analyses were performed with the help of Web of Science analysis service. In the current database of vision science literature, Nepalese authors contributed 112 publications to Web of Science, 95 of which were original articles. Pokharel GP had the highest number of citations among contributing authors of Nepal. Hennig A contributed the highest number of article as a first author. The Nepal Eye Hospital contributed the highest number of articles as an institution to the field of Vision Science. Currently, only two journals from Nepal including Journal of Nepal Medical Association (JAMA) are indexed in the Web of Science database (Sieving, 2012). To evaluate the total productivity of vision science literature from Nepal, total publication counts from national journals and articles indexed in other databases such as PubMed and Scopus must also be considered. © NEPjOPH.

The April 2015 Gorkha Nepal earthquake revealed the relative effectiveness of the Nepal Standard, or national building code (NBC), and irregular compliance with it in different parts of Nepal. Much of the damage to more than half a million Nepal's residential structures may be attributed to the prevalence of owner-built or owner-supervised construction and the lack of owner and builder responsiveness to seismic risk and training in the appropriate means of complying with the NBC. To explain these circumstances, we review the protracted implementation of the NBC and the role played by one organization, the National Society for Earthquake Technology-Nepal (NSET), in the NBC's implementation. We also share observations on building code compliance made by individuals in Nepal participating in workshops led by the Earthquake Engineering Research Institute's 2014 class of Housner Fellows.

Transportation activities can contribute to accumulation of heavy metals in roadside soil and grass, which could potentially compromise public health and the environment if the roadways cross farmland areas. Particularly, heavy metals may enter the food chain as a result of their uptake by roadside edible grasses. This research was conducted to investigate heavy metal (Cu, Zn, Cd, and Pb) concentrations in roadside farmland soils and corresponding grasses around Kathmandu, Nepal. Four factors were considered for the experimental design, including sample type, sampling location, roadside distance, and tree protection. A total of 60 grass samples and 60 topsoil samples were collected under dry weather conditions. The Multivariate Analysis of Variance (MANOVA) results indicate that the concentrations of Cu, Zn, and Pb in the soil samples are significantly higher than those in the grass samples; the concentrations of Cu and Pb in the suburban roadside farmland are higher than those in the rural mountainous roadside farmland; and the concentrations of Cu and Zn at the sampling locations with roadside trees are significantly lower than those without tree protection. The analysis of transfer factor, which is calculated as the ratio of heavy-metal concentrations in grass to those in the corresponding soil, indicates that the uptake capabilities of heavy metals from soil to grass is in the order of Zn > Cu > Pb. Additionally, it is found that as the soils’ heavy-metal concentrations increase, the capability of heavy-metal transfer to the grass decreases, and this relationship can be characterized by an exponential regression model.

Delayed cord clamping at birth has shown to benefit neonates with increased placental transfusion leading to higher haemoglobin concentrations, additional iron stores and less anaemia later in infancy, higher red blood cell flow to vital organs and better cardiopulmonary adaptation. As iron deficiency in infants even without anaemia has been associated with impaired development, delayed cord clamping seems to benefit full term infants also in regions with a relatively low prevalence of iron deficiency anaemia. In Nepal, there is a high anaemia prevalence among children between 6 and 17 months (72-78 %). The objective of the proposed study is to evaluate the effects of delayed and early cord clamping on anaemia (and haemoglobin level) at 8 and 12 months, ferritin at 8 and 12 months, bilirubin at 2-3 days, admission to Neonatal Intensive Care Unit (NICU) or special care nursery, and development at 12 and 18-24 months of age. A randomized, controlled trial comparing delayed and early cord clamping will be implemented at Paropakar Maternity and Women's Hospital in Kathmandu, Nepal. Pregnant woman of gestational age 34-41 weeks who deliver vaginally will be included in the study. The interventions will consist of delayed clamping of the umbilical cord (≥180 s after delivery) or early clamping of the umbilical cord (≤60 s). At 8 and 12 months of age, infant's iron status and developmental milestones will be measured. This trial is important to perform because, although strong indications for the beneficial effect of delayed cord clamping on anaemia at 8 to 12 months of age exist, it has not yet been evaluated by a randomized trial in this setting. The proposed study will analyse both outcome as well as safety effects. Additionally, the results may not only contribute to practice in Nepal, but also to the global community, in particular to other low-income countries with a high prevalence of iron deficiency anaemia.

School-based sex education is an effective medium to convey health information and skills about preventing sexually transmitted infections (STIs) and unwanted pregnancies among adolescents. However, research on school-based sex education is limited in many developing countries, including Nepal. This study thus had two main objectives: (1) to assess students' evaluation of school-based sex education, and (2) to examine the associations between students' evaluations of school-based sex education and their (a) attitudes toward abstinence and (b) intentions for safer sex. This cross-sectional study was conducted among 634 students from six schools in the Kathmandu Valley during May-June 2010. We used a self-administered questionnaire to assess students' evaluations of school-based sex education, attitudes toward abstinence, and intentions for safer sex. The data were then analyzed using multiple linear regression models. Regarding "information on HIV and sexual health", many students perceived that they received the least amount of information on HIV counseling and testing centers (mean 2.29, SD 1.00) through their schools. In terms of "support and involvement of teachers and parents" in sex education, parents' participation ranked as the lowest (mean 1.81, SD 1.01). Audiotapes were reported as the least used among the listed "teaching aids for sexual health education" (mean 1.54, SD 0.82). In multivariate analysis, receiving more "information on HIV and sexual health" was positively associated with more positive "attitudes toward abstinence" (β = 0.11, p = <0.018) and greater "intentions for safer sex" (β = 0.17, p = <0.001) among students. Similarly, increased "support and involvement from teachers and parents" was also positively associated with more positive "attitudes toward abstinence" (β = 0.16, p = <0.001) and greater "intentions for safer sex" (β = 0.15, p = <0.002).

River response to strong earthquake shaking in mountainous terrain often entails the flushing of sediments delivered by widespread co-seismic landsliding. Detailed mass-balance studies following major earthquakes in China, Taiwan, and New Zealand suggest fluvial recovery times ranging from several years to decades. We report a detailed chronology of earthquake-induced valley fills in the Pokhara region of western-central Nepal, and demonstrate that rivers continue to adjust to several large medieval earthquakes to the present day, thus challenging the notion of transient fluvial response to seismic disturbance. The Pokhara valley features one of the largest and most extensively dated sedimentary records of earthquake-triggered sedimentation in the Himalayas, and independently augments paleo-seismological archives obtained mainly from fault trenches and historic documents. New radiocarbon dates from the catastrophically deposited Pokhara Formation document multiple phases of extremely high geomorphic activity between ˜700 and ˜1700 AD, preserved in thick sequences of alternating fluvial conglomerates, massive mud and silt beds, and cohesive debris-flow deposits. These dated fan-marginal slackwater sediments indicate pronounced sediment pulses in the wake of at least three large medieval earthquakes in ˜1100, 1255, and 1344 AD. We combine these dates with digital elevation models, geological maps, differential GPS data, and sediment logs to estimate the extent of these three pulses that are characterized by sedimentation rates of ˜200 mm yr-1 and peak rates as high as 1,000 mm yr-1. Some 5.5 to 9 km3 of material infilled the pre-existing topography, and is now prone to ongoing fluvial dissection along major canyons. Contemporary river incision into the Pokhara Formation is rapid (120-170 mm yr-1), triggering widespread bank erosion, channel changes, and very high sediment yields of the order of 103 to 105 t km-2 yr-1, that by far outweigh bedrock denudation rates

Background Primary open-angle glaucoma (POAG) is one of the most common causes of irreversible blindness. A possible association between POAG and non-communicable diseases such as hypertension and diabetes suggests that the incidence of POAG may increase. People with POAG in Nepal usually present late to hospital and have poor knowledge of glaucoma. Objectives Anticipating a knowledge gap regarding these diseases, this study aimed to explore the knowledge of POAG, hypertension, and diabetes in the community and barriers to health care. Design We conducted this qualitative study in the Jhaukhel-Duwakot Health Demographic Surveillance Site (JD-HDSS), a peri-urban community near Kathmandu, a capital city of Nepal. To study how disease influences knowledge, we conducted focus group discussions separately for men and women with and without pre-existing POAG, hypertension, and diabetes. Data were analyzed using the framework analysis approach. Results Although people suffering from POAG, hypertension, and/or diabetes exhibited adequate knowledge of hypertension and diabetes, they lacked in-depth knowledge of POAG. People believed mostly in internal health locus of control. Perception of disease consequences and impact of disease on daily life was influenced by pre-existing POAG, hypertension, and/or diabetes but only in men. Gender disparity was observed regarding health literacy, health perception, and health barriers, which put women in a more difficult situation to tackle their health. We also revealed a gap between knowledge, attitude, and practice of health among women and healthy men. Conclusion Although people in JD-HDSS exhibited adequate knowledge regarding hypertension and diabetes, they lacked in-depth knowledge about POAG. This study demonstrated gender difference in health literacy and access to health care, making women more vulnerable towards disease. We also demonstrated a gap between knowledge, attitude, and practice of health. However, tailored health

Coulomb Stress Change and Seismic Hazard of Rift Zones in Southern Tibet after the 2015 Mw7.8 Nepal Earthquake and Its Mw7.3 Aftershock

In southern Tibet (30~34N, 80~95E), many north-trending rifts, such as Yadong-Gulu and Lunggar rifts, are characterized by internally drained graben or half-graben basins bounded by active normal faults. Some developed rifts have become a portion of important transportation lines in Tibet, China. Since 1976, eighty-seven >Mw5.0 earthquakes have happened in the rift regions, and fifty-five events have normal faulting focal mechanisms according to the GCMT catalog. These rifts and normal faults are associated with both the EW-trending extension of the southern Tibet and the convergence between Indian and Tibet. The 2015 Mw7.8 Nepal great earthquake and its Mw7.3 aftershock occurred at the main Himalayan Thrust zone and caused tremendous damages in Kathmandu region. Those earthquakes will lead to significant viscoelastic deformation and stress changes in the southern Tibet in the future. To evaluate the seismic hazard in the active rift regions in southern Tibet, we modeled the slip distribution of the 2015 Nepal great earthquakes using the InSAR displacement field from the ALOS-2 satellite SAR data, and calculated the Coulomb failure stress (CFS) on these active normal faults in the rift zones. Because the estimated CFS depends on the geometrical parameters of receiver faults, it is necessary to get the accurate fault parameters in the rift zones. Some historical earthquakes have been studied using the field data, teleseismic data and InSAR observations, but results are in not agreement with each other. In this study, we revaluated the geometrical parameters of seismogenic faults occurred in the rift zones using some high-quality coseismic InSAR observations and teleseismic body-wave data. Finally, we will evaluate the seismic hazard in the rift zones according to the value of the estimated CFS and aftershock distribution.

The Himalayas and their foreland belong to the world's most earthquake-prone regions. With millions of people at risk from severe ground shaking and associated damages, reliable data on the spatial and temporal occurrence of past major earthquakes is urgently needed to inform seismic risk analysis. Beyond the instrumental record such information has been largely based on historical accounts and trench studies. Written records provide evidence for damages and fatalities, yet are difficult to interpret when derived from the far-field. Trench studies, in turn, offer information on rupture histories, lengths and displacements along faults but involve high chronological uncertainties and fail to record earthquakes that do not rupture the surface. Thus, additional and independent information is required for developing reliable earthquake histories. Here, we present exceptionally well-dated evidence of catastrophic valley infill in the Pokhara Valley, Nepal. Bayesian calibration of radiocarbon dates from peat beds, plant macrofossils, and humic silts in fine-grained tributary sediments yields a robust age distribution that matches the timing of nearby M>8 earthquakes in ~1100, 1255, and 1344 AD. The upstream dip of tributary valley fills and X-ray fluorescence spectrometry of their provenance rule out local sediment sources. Instead, geomorphic and sedimentary evidence is consistent with catastrophic fluvial aggradation and debris flows that had plugged several tributaries with tens of meters of calcareous sediment from the Annapurna Massif >60 km away. The landscape-changing consequences of past large Himalayan earthquakes have so far been elusive. Catastrophic aggradation in the wake of two historically documented medieval earthquakes and one inferred from trench studies underscores that Himalayan valley fills should be considered as potential archives of past earthquakes. Such valley fills are pervasive in the Lesser Himalaya though high erosion rates reduce

Impacts of the 2016 outburst flood on the Bhote Koshi River valley, central Nepal

The central Nepal Himalaya is a region of rapid erosion where fluvial processes are largely driven by the annual Indian Summer Monsoon, which delivers up to several meters of precipitation each year. However, the rivers in this region are also subject to rare catastrophic floods caused by the sudden failure of landslide or moraine dams. Because these floods happen rarely, it has been difficult to isolate their impact on the rivers and adjacent hillslopes, and their importance for the long-term evolution of Himalayan rivers is poorly constrained. On the 5th of July, 2016, the Bhote Koshi River in central Nepal was hit by a glacial lake outburst flood (GLOF). The flood passed through a seismic and hydrological observatory installed along the river in June 2015, and we have used the resulting data to constrain the timing, duration, and bedload transport properties of the outburst flood. The impact of the flood on the river can be further observed with hourly time-lapse photographs, daily measurements of suspended sediment load, repeat lidar surveys, and satellite imagery. Overall, our observatory data span two monsoon seasons, allowing us to evaluate the impacts of the outburst flood relative to the annual monsoon flood. The outburst flood affected the river on several timescales. In the short term, it transported large amounts of coarse sediment and restructured the river bed during the hours of the flood pulse itself. Over intermediate timescales it resulted in elevated bedload and suspended load transport for several weeks following the flood. Over longer timescales the flood undercut and destabilized the river banks and hillslopes in a number of locations, leading to bank collapses, slumps, and landslides. We map changes in the channel and associated mass wasting using rapidEye imagery from Oct. 2015 and Oct. 2016. We also use repeat terrestrial lidar scans to quantify the magnitude of change in multiple locations along the river channel and to measure bank

Since the 1950 invasion of Tibet by China, Tibetan refugees have attempted to flee into Nepal over the Himalayan mountains. We documented the experiences of a group of refugees making this journey. We conducted semistructured interviews with 50 recent refugees at the Tibetan Refugee Transit Centre in Kathmandu, Nepal. Participants ranged in age from 8 to 56 years, and 21 were female. The average length of their journey from Tibet to Nepal was 34 days. During their journey, a majority of the refugees encountered authorities or became involved in altercations with Nepali Maoist groups. Most of these interactions resulted in extortion and threats of expulsion. Several Tibetans were tortured, beaten with weapons, threatened with being shot, and robbed. Three women were sexually assaulted at gunpoint. The refugees who took part in this study experienced physical and mental hardships and, often, human rights abuses on their journey to Nepal. International pressure is needed to prevent human rights violations and reduce potential long-term physical and mental health effects associated with this dangerous crossing.

Adventure travel necessarily places travelers at risk of environmental hazards. We assessed the burden of "environmental" hazards among a cohort of travelers and expatriates presenting to a large travel clinic in Nepal. Data on travelers and expatriates seen at the Canadian International Water and Energy Consultants (CIWEC) clinic in Kathmandu were prospectively collected and entered into the GeoSentinel Surveillance Network database. Data on individuals receiving predefined diagnoses related to environmental hazards were extracted and analyzed. Of 10,499 travelers and 4,854 expatriates in the database, 2,160 were diagnosed with 2,533 environment-related illnesses. Injuries were common among both travelers and expatriates [N= 788 (6.1%) and 328 (4.9%), respectively], while altitude illness was seen almost exclusively in travelers [N= 611 (4.7%) vs N= 8 (0.1%)]. Factors independently associated with environmental diagnoses include male gender (p < 0.001), traveling for tourism (p < 0.001), and lack of pre-travel advice (p= 0.043). Three percent of travelers and 2% of expatriates presenting to CIWEC sustained a bite wound or required rabies postexposure prophylaxis. Injured travelers were less likely than others to have obtained pre-travel advice (p= 0.003), while those who sustained bite wounds were more likely to have received pre-travel advice (p < 0.001). Environmental hazards are important causes of morbidity and potential mortality among adventure travelers and expatriates. Current pre-travel interventions are missing certain risk groups entirely and failing to have the desired educational impact in others.

Some people host lice on the clothing as well as the head. Whether body lice and head lice are distinct species or merely variants of the same species remains contentious. We sought to ascertain the extent to which lice from these different habitats might interbreed on doubly infected people by comparing their entire mitochondrial genome sequences. Toward this end, we analyzed two sets of published genetic data from double-infections of body lice and head lice: 1) entire mitochondrial coding regions (≈15.4 kb) from body lice and head lice from seven doubly infected people from Ethiopia, China, and France; and 2) part of the cox1 gene (≈486 bp) from body lice and head lice from a further nine doubly infected people from China, Nepal, and Iran. These mitochondrial data, from 65 lice, revealed extraordinary variation in the number of single nucleotide polymorphisms between the individual body lice and individual head lice of double-infections: from 1.096 kb of 15.4 kb (7.6%) to 2 bps of 15.4 kb (0.01%). We detected coinfections of lice of Clades A and C on the scalp hair of three of the eight people from Nepal: one person of the two people from Kathmandu and two of the six people from Pokhara. Lice of Clades A and B coinfected the scalp hair of one person from Atherton, Far North Queensland, Australia. These findings argue for additional large-scale studies of the body lice and head lice of double-infected people. © 2014 Entomological Society of America.

Medical waste is considered as a major public health hazard. In a developing country like Nepal, there is much concern about the management practice of medical waste. This study aimed to assess Health Care Waste Management practice among Health Care Institutions in Nepal. A cross sectional study was carried out between July 2012 to June 2013 in 62 different Health Care Institutions, selected from stratified proportionate random sampling technique from all administrative regions of Nepal. A structured questionnaire and observation checklist were used for data collection. The waste generation rate is found significantly correlated with bed capacity, patient flow rate and annual budget spent in the hospital. It is found significantly higher in Teaching hospital than other Health Care Institutions of Nepal. An average of 3.3 kg/day/patient of medical waste (2.0 kg/day/patient non-hazardous and 1.0 kg/day/patient hazardous waste) was generated during the study period. Further, it was found that most of the Health care wastes were not disinfected before transportation to waste disposal sites. Very limited number of Health Care Institutions had conducted Environmental Assessment. Similarly, some of the Health Care Institutions had not followed Health care waste management guideline 2009 of Nepal Government. We found poor compliance of medical waste management practice as per existing legislation of Government of Nepal. Hence, additional effort is needed for improvement of Health care waste management practice at Health Care Institutions of Nepal.

To develop space activities and to industrialize astronomy, base of space education in the high schools must be very effective. This paper highlights the present scenario of space education and discusses the syllabus of astronomy in the different education level of Nepal. Astronomy is included in the curriculum of science book of middle school and high school which contains very few contents of solar system, constellations, galaxy, black holes and formation of stars. There is no any degree for higher studies in astronomy as a separate department in any university of Nepal. This paper also highlights the space activities and national level programs conducting in Nepal to support astronomy education. With the rise of many astronomical clubs and societies in the different regions of Nepal, astronomy education has been more effective in the recent time. Series of Galileo Teacher's Training Program in the different parts of Nepal being organized by Global Hands on Universe in cooperation with local astronomy clubs will be discuss in brief. The attempts to bring more trained and skilled teachers in the classroom by the government and non-government agencies are now gradually increasing. The competition of private schools and their capacity building workshops to their teachers to attract more students is also playing active role to shape the school education effective. The challenges, prospects and the practice of effective astronomy education prevailing in Nepal will be discuss. Key Words: Nepal, Astronomy Education, GTTP, Trained Teachers

In Nepal, prevalence of Hepatitis C (HCV) among injecting drug users (IDUs) has been measured at 50% and knowledge of the virus is low. Rehabilitation and harm reduction attendees constitute populations to whom health care providers can deliver services. As such, characterizing their drug use and risk profiles is important for developing targeted service delivery. We measured drug use and risk patterns of IDUs participating in residential rehabilitation as well as those contacted through needle exchanges to identify correlates of drug use frequency, risky injection practices as well as HCV testing, knowledge and perceived risk. We collected cross-sectional data from one-on-one structured interviews of IDUs contacted through needle-exchange outreach workers (n=202) and those attending rehabilitation centres (behaviour immediately prior to joining rehabilitation) (n=167). Roughly half of participants reported injecting at least 30 times in the past 30 days and individuals with previous residential rehabilitation experience reported frequent injection far more than those without it. About one in fourteen respondents reported past week risky injection practices. Participants were over three times as likely to report risky injection if they consumed alcohol daily (17.2%) than if they did not (5.0%) (p=0.002). Those who reported injecting daily reported risky injection practices (11.9%) significantly more than non-daily injectors (1.8%) (p<0.001). Respondents reported high HCV infection rates, low perceived risk, testing history and knowledge. HCV knowledge was not associated with differences in risky injecting. Treatment centres should highlight the link between heavy drinking, frequent injection and risky injecting practices. The link between rehabilitation attendance and frequent injection may suggest IDUs with more severe use patterns are more likely to attend rehabilitation. Rehabilitation centres and needle exchanges should provide testing and education for HCV

Nepal has a complicated geophysical structure that is prone to various kinds of disasters. Nepal ranks the most disaster-prone country in the world and has experienced several natural calamities, causing high property and life losses. Disasters are caused by natural processes, but may be increased by human activities. The overall objective of this paper is to analyze the disaster risk profile and existing legal framework of Nepal. The paper is based on secondary data sources. Major causative factors for floods and landslides are heavy and continuous rainfall, outburst floods, infrastructure failure, and deforestation. Historical data of natural disasters in Nepal show that water-induced disasters have killed hundreds of people and affected thousands every year. Likewise, properties worth millions of US dollars have been damaged. There is an increasing trend toward landslides and floods, which will likely continue to rise if proper intervention is not taken. A positive correlation between water-induced disasters and deaths has been observed. Nepal has a poor Index for Risk Management (INFORM). There are fluctuations in the recording of death data caused by flood and landslides. The Government of Nepal focuses more on the response phase than on the preparedness phase of disasters. The existing disaster management act seems to be weak and outdated. There is a gap in current legal procedure, so the country is in dire need of a comprehensive legal framework. The new proposed act seems to take a much broader approach to disaster management. With a long-term vision of managing disaster risk in the country, the Government of Nepal has begun the Nepal Risk Reduction Consortium (NRRC) in collaboration with development and humanitarian partners. In order to improve the vulnerability of Nepal, an early warning system, mainstreaming disasters with development, research activities, community participation and awareness, and a rainfall monitoring system must all be a focus.

Nepal is highly vulnerable to global climate change, despite its negligible emission of global greenhouse gases. The vulnerable climate-sensitive sectors identified in Nepal's National Adaptation Programme of Action (NAPA) to Climate Change 2010 include agriculture, forestry, water, energy, public health, urbanization and infrastructure, and climate-induced disasters. In addition, analyses carried out as part of the NAPA process have indicated that the impacts of climate change in Nepal are not gender neutral. Vector-borne diseases, diarrhoeal diseases including cholera, malnutrition, cardiorespiratory diseases, psychological stress, and health effects and injuries related to extreme weather are major climate-sensitive health risks in the country. In recent years, research has been done in Nepal in order to understand the changing epidemiology of diseases and generate evidence for decision-making. Based on this evidence, the experience of programme managers, and regular surveillance data, the Government of Nepal has mainstreamed issues related to climate change in development plans, policies and programmes. In particular, the Government of Nepal has addressed climate-sensitive health risks. In addition to the NAPA report, several policy documents have been launched, including the Climate Change Policy 2011; the Nepal Health Sector Programme - Implementation Plan II (NHSP-IP 2) 2010-2015; the National Health Policy 2014; the National Health Sector Strategy 2015-2020 and its implementation plan (2016-2021); and the Health National Adaptation Plan (H-NAP): climate change and health strategy and action plan (2016-2020). However, the translation of these policies and plans of action into tangible action on the ground is still in its infancy in Nepal. Despite this, the health sector's response to addressing the impact of climate change in Nepal may be taken as a good example for other low- and middle-income countries.

HIV epidemic in Far-Western Nepal: effect of seasonal labor migration to India

PubMed Central

2011-01-01

Background Because of limited work opportunities in Nepal and the open-border provision between Nepal and India, a seasonal labor migration of males from Far-Western Nepal to India is common. Unsafe sexual activities of these migrants in India, such as frequent visits to brothels, lead to a high HIV prevalence among them and to a potential transmission upon their return home to Nepal. The present study aims to evaluate the role of such seasonal labor-migration to India on HIV transmission in Far-Western Nepal and to assess prevention programs. Methods An HIV epidemic model was developed for a population in Far-Western Nepal. The model was fitted to the data to estimate the back and forth mobility rates of labor-migrants to India, the HIV prevalence among migrants and the HIV transmission rate in Far-Western Nepal. HIV prevalence, new infections, disease deaths and HIV infections recruited from India were calculated. Prevention programs targeting the general population and the migrants were evaluated. Results Without any intervention programs, Far-Western Nepal will have about 7,000 HIV infected individuals returning from India by 2015, and 12,000 labor-migrants living with HIV in India. An increase of condom use among the general population from 39% to 80% will reduce new HIV infections due to sexual activity in Far-Western Nepal from 239 to 77. However, such a program loses its effectiveness due to the recruitment of HIV infections via returning migrants from India. The reduction of prevalence among migrants from 2.2% to 1.1% can bring general prevalence down to 0.4% with only 3,500 recruitments of HIV infections from India. Conclusion Recruitment of HIV infections from India via seasonal labor-migrants is the key factor contributing to the HIV epidemic in Far-Western Nepal. Prevention programs focused on the general population are ineffective. Our finding highlights the urgency of developing prevention programs which reduce the prevalence of HIV among migrants

Hazard Assessment of Glacial Lake Outburst Flood and Potential of ICTs for Coping: A Case of Eastern Himalaya of Nepal

2014-12-01

Alarming rate of retreat of glaciers and formation of glacial lakes in higher elevation of Nepal Himalaya has been reported to be related with the pronounced atmospheric temperature rise in the region. Glacier Lake Outburst Floods (GLOF) are the growing climate induced hazards in the Himalaya increasing the vulnerability of community living in the mountain valley, and the fragile ecosystem. This study tried to come up with the potential impacts from glacial lake outburst flood (GLOF) in highland of eastern region of Nepal and potential role of Information Communication Technologies (ICT) in coping. I analyzed the trend of climatic pattern (temperature and precipitation) of the Eastern Himalaya Region of Nepal available from Department of Hydrology and Meteorology (DHM), Government of Nepal, and also prepared the latest location map of the glacial lakes using google earth and ArcGIS application in the highland of the Kanchanjungha Conservation Area of the region. Tiptala glacial lake, located at an elevation of 4950 masl, within the conservation area, was selected for the GLOF hazard assessment. I used semi-structured questioner survey and key informants interviews in the community living below the lake in the highland of the study area in order to assess the potential hazard of GLOF. Analysis shows the increasing trend of atmospheric temperature in the region. With the varying sizes, 46 glacial lakes were located in the region, which covers over 2.57 sq. km in total. Though the larger portion of the downstream area of the Tiptala glacial lake fall in the remote location away from major residential area, few villages, major pasture lands for Yaks, foot trails, and several bridges across the Tamor River below the lake are in risk of GLOF. Poor access due to extreme geographical remoteness and capacity to afford the modern technologies in the community is seen as the major limiting factor to the knowledge and information about the climate change and related impacts

Variable shortening on the Main Frontal Thrust in Nepal

The Main Frontal Thrust (MFT) is the youngest, most active, and southernmost thrust system in the Himalaya. It is located in the footwall of the Main Boundary thrust (MBT), deforming Miocene to Pliocene age Siwalik Group rocks. Although often considered a single, continuous fault, in reality as many as four subparallel faults, spaced 5-30 km apart, make up this fault system. Estimates of total shortening across the MFT for eastern and central Nepal vary from 15 to 40 km, based on cross-sections and surface measurements. However, when the same methods are applied, shortening does not vary significantly along strike (Hirschmiller et al., 2014), suggesting contrasting methodologies rather than a difference in interpreted along strike structural history. Based on high resolution seismic reflection imaging, we present new interpretations of total shortening recorded by the MFT system in central vs. eastern Nepal (200 km apart), together with a detailed transect of field observations in central Nepal. Our structural interpretations demonstrate that the geological shortening recorded on the MFT ranges from >20 km in central Nepal to <1 km in far eastern Nepal. Geodetic measurements show only a slight decrease in interseismic convergence from central (15±1 mm/yr) to eastern Nepal (14±1 mm/yr) and therefore cannot explain this dramatic difference (Lindsey et al., in prep). Taken at face value, these results imply that the MBT must have been much more recently active in eastern Nepal ( 70 ka) than central Nepal ( 1.4 Ma). We propose an alternative model that does not require this dramatic difference in the age of the MFT. As one end-member, it is indeed possible that the MFT may have broken forward much more recently in the east. However, it is also possible that older MFT thrust sheets have formed, and then have been consumed as the MBT passively slid south in the hanging wall of the MFT. Distinguishing between these models is important not only for understanding the

Mass Media and Rural Out-Migration in the Context of Social Change: Evidence from Nepal

PubMed Central

Piotrowski, Martin

2011-01-01

This work examines the influence of mass media on rural out-migration using historical and contemporary data from a setting experiencing massive social and economic development in the last half-century. Data come from the Chitwan Valley Family Study, an ongoing study of an agrarian region in rural Nepal. Media are hypothesized to affect migration by inducing attitudinal and behavioral changes similar to those of other determinants of migration. As their influence differs from other determinants in important ways, media represent a unique form of influence that should be taken into account. I find that movie and television exposure are significant determinants of out-migration in historical contexts, although television exposure was important in more contemporary contexts. Differences in these effects probably indicate the timing of the spread of each type of media and changing preferences among media consumers. PMID:23894210

Soil Bioengineering Application and Practices in Nepal

2013-02-01

The small mountainous country Nepal is situated in the central part of the Himalayas. Its climate varies from tropical in the south to arctic in the north; and natural vegetation follows the pattern of climate and altitude. Water-induced disaster problems including soil erosion, debris flow, landslides and flooding are common due to the unstable landscape. Soil erosion is the most important driving force for the degradation of upland and mountain ecosystems. Soil bioengineering has been used in Nepal for nearly 30 years to deal with erosion problems on slopes, in high way construction and riverbank stabilization. The main soil bioengineering techniques used in Nepal are brush layering, palisades, live check dams, fascines and vegetative stone pitching. This study is based on the geology, climate and vegetation of Nepal and briefly summarizes the application of soil bioengineering on slopes and stream banks, with especial attention to the role of vegetation on slope and stream bank stabilization. Furthermore, this paper addresses the role of community participation and responsibility for successful application of vegetation-based techniques in management, maintenance and utility aspects for the future. In recent years, soil bioengineering techniques are extensively used due to their cost-effectiveness, using locally available materials and low-cost labour in comparison to more elaborate civil engineering works. However, scientific implementation and record-keeping and evaluation of the work are indeed essential.

Scrub typhus is a neglected tropical disease and is under reported from Nepal. The objective of this study was to investigate the sero-epidemiology of scrub typhus in patients suffering from acute febrile illness. A total of 434 specimens collected from July to November 2015 at National Public Health Laboratory (NPHL) were investigated for detection of immunoglobulin M (IgM) antibody to Orientiatsutsugamushi.The Scrub Typhus Detect TM kit (InBios, USA) was used to detect the antibodies to O.tsutsugamushi in human serum. Randomly selected 10% positive specimens were used for confirmation by dot- enzyme-linked immunosorbent assay and indirect immunofluorescence assay. Of the total, 175 (40.3%) were positive for IgM antibodies to O. tsutsugamushi. Positive results of scrub typhus were highest among female in 11-20 year followed by males in 41-50 years age group. The IgM antibodies to O. tsutusugamushi were positive in specimens of various geographical regions including 30 districts of Nepal. Positive cases were found in various ecological regions of Nepal. Scrub typhus is one of the neglected tropical diseases in Nepal. Patients with acute febrile illness should be investigated for scrub typhus with high priority. There is an urgent need of reliable and affordable diagnostic tests at all level of health facilities of Nepal. Surveillance and public health awareness about the disease transmission and preventive measures needs to be initiated.

Indigenous biocultural knowledge is a vital part of Nepalese environmental management strategies; however, much of it may soon be lost given Nepal's rapidly changing socio-ecological climate. This is particularly true for knowledge surrounding parasitic and mycoheterotrophic plant species, which are well represented throughout the Central-Eastern Himalayas but lack a collated record. Our study addresses this disparity by analyzing parasitic and mycoheterotrophic plant species diversity in Nepal as well as the ethnobotanical knowledge that surrounds them. Botanical texts, online databases, and herbarium records were reviewed to create an authoritative compendium of parasitic and mycoheterotrophic plant species native or naturalized to the Nepal Central-Eastern Himalaya. Semi-structured interviews were then conducted with 141 informants to better understand the biocultural context of these species, emphasizing ethnobotanical uses, in 12 districts of Central-Eastern Nepal. Nepal is a hotspot of botanical diversity, housing 15 families and 29 genera of plants that exhibit parasitic or mycoheterotrophic habit. Over 150 of the known 4500 parasitic plant species (~3 %) and 28 of the 160 mycoheterotrophic species (~18 %) are native or naturalized to Nepal; 13 of our surveyed parasitic species are endemic. Of all species documented, approximately 17 % of parasitic and 7 % of mycoheterotrophic plants have ethnobotanical uses as medicine (41 %), fodder (23 %), food (17 %), ritual objects (11 %), or material (8 %). Parasitic and mycoheterotrophic plant species exhibit high diversity in the Nepal Central-Eastern Himalaya and are the fodder for biocultural relationships that may help inform future environmental management projects in the region.

Eighty-one Fasciola flukes collected from 8 districts in Nepal were analyzed for their species identification on the basis of their spermatogenic status and nuclear ribosomal internal transcribed spacer 1 (ITS1) and for their phylogenetic relation with Fasciola flukes from other Asian countries on the basis of the mitochondrial NADH dehydrogenase subunit 1 (nad1) gene. Sixty-one flukes (75.3%) were aspermic Fasciola sp., and 20 flukes (24.7%) were identified as Fasciola gigantica. All of the aspermic flukes displayed the Fh/Fg type in ITS1, which was predominant in aspermic Fasciola sp. from China, and most (60 flukes) displayed the Fsp-ND1-N1 haplotype in the nad1, which had an identical nucleotide sequence to the major haplotype (Fg-C2) of the aspermic flukes from China. These results suggest that aspermic Fasciola sp. was introduced into Nepal from China. Furthermore, the results of the diversity indices, neutrality indices, and median-joining network analysis with reference haplotypes from Asian countries suggest that aspermic Fasciola sp. rapidly expanded its distribution. In contrasts, F. gigantica displayed 10 nad1 haplotypes, which showed higher population diversity indices than the haplotypes of aspermic flukes, indicating that the F. gigantica population was clearly distributed in Nepal earlier than the aspermic Fasciola population. Although the F. gigantica haplotypes from Nepal formed a star-like phylogeny consisting of a main founder haplotype (Fg-ND1-N1), together with some F. gigantica haplotypes from Myanmar and Thailand, the Nepal population differed genetically from F. gigantica populations of neighboring countries as each country had distinct founder haplotype(s).

Japanese encephalitis is frequent in Asia, with a severe prognosis, but rare in travelers. Culex mosquitoes transmit Japanese encephalitis virus. Risk factors are destination, duration of stay, summer and fall seasons, outdoor activities, and type of accommodation. We report the case of a French traveler to Nepal with neutralization-based serological confirmed Japanese encephalitis. He presented classical clinical (viral syndrome before an encephalitis status with behavioral disorder, global hypotonia, mutism, movement disorders, seizure, and coma), radiological (lesions of thalami, cortico-spinal tracts, and brainstem) and biological features (lymphocytic meningitis). Nowadays, the presence of Japanese encephalitis virus in Nepal, including mountain areas, is established but Japanese encephalitis remains rare in travelers returning from this area and neurologist physicians need to become familiar with this. We recommend vaccination for travelers spending a long period of time in Nepal and having at-risk outdoor activities.

Assessment of Drought Scenario in Western Nepal

Drought is a frequent phenomenon in relatively drier western Nepal. Lack of hydro-climatic information with wider spatial coverage is hindering effective assessment of the drought events. Furthermore, drought assessment is not getting adequate attention in Nepal. This study aims to develop drought scenario for Western Nepal by evaluating various types of drought indices in Karnali River Basin (area = 4,6150 km2) and recommend the most suited set of indices for data-poor regions. On the climatic data at ten stations, drought indices were calculated from following seven selected indices: Standardized Precipitation Index (SPI), Standardized Precipitation Evapotranspiration Index (SPEI), Palmer Drought Severity Index (PDSI), (self-calibrating) Palmer Drought Severity Index (scPDSI), Reconnaissance Drought Index (RDI), Standardized Streamflow Index (SSFI), and Palmer Hydrological Drought Index (PHDI). Initial results reflect that the basin is affected by severe meteorological drought. Most of the indices show the extreme dryness scenario during the years 1984-85, 1992-93, 1995, 2000, 20002, 2008-09, and 2012. The results from the stations with long-term temperature and precipitation data sets showed a higher (up to 0.9) correlation between SPI and RDI than for SPEI and other Palmer Drought Indices, which ranged from 0.6 to 0.8 only. This suggests ability of SPI to represent magnitude and duration of the drought events fairly well in the study basin, and therefore, has potential to represent drought dynamics in data-poor regions.

Level of awareness about legalization of abortion in Nepal: a study at Nepal Medical College Teaching Hospital.

PubMed

Tuladhar, H; Risal, A

2010-06-01

World Health Organization (WHO) estimates that about 25.0% of all pregnancies worldwide end in induced abortion, approximately 50 million each year. More than half of these abortions are performed under unsafe conditions resulting in high maternal mortality ratio specially in developing countries like Nepal. Abortion was legalized under specified conditions in March 2002 in Nepal. But still a large proportion of population are unaware of the legalization and the conditions under which it is permitted. Legal reform alone cannot reduce abortion related deaths in our country. This study was undertaken with the main objective to study the level of awareness about legalization of abortion in women attending gyne out patients department of Nepal Medical College Teaching Hospital (NMCTH), which will give a baseline knowledge for further dissemination and advocacy about abortion law. Total 200 women participated in the study. Overall 133 (66.5%) women said they were aware of legalization of abortion in Nepal. Women of age group 20-34 years, urban residents, service holders, Brahmin/Chhetri caste and with higher education were more aware about it. Majority (92.0%) of the women received information from the media. Detail knowledge about legal conditions under which abortion can be performed specially in second trimester was found to be poor. Large proportion (71.0%) of the women were still unaware of the availability of comprehensive abortion care services at our hospital, which is being provided since last seven years. Public education and advocacy campaigns are crucial to create awareness about the new legislation and availability of services. Unless the advocacy and awareness campaign reaches women, they are not likely to benefit from the legal reform and services.

Nutritional assessment of community-dwelling older adults in rural Nepal.

Demographic transition in Nepal, like in many developing countries, has resulted in a burgeoning elderly population whose health status is not currently monitored. One pillar of health is adequate nutrition. Yet, little is known about the nutritional health status of the elderly in Nepal. The financial, material, and personnel limitations in Nepal's health delivery services necessitate health screening instruments that require minimal clinical staff and resources. To our knowledge, no such nutritional assessment tool has been validated in Nepal. Therefore, our aims are two-fold: To assess the nutritional status of the elderly population in one typical Nepali village, Okharpauwa, in Nuwakot District, Nepal; and concurrently, to validate the Mini Nutritional Assessment (MNA) tool. A cross-sectional field study was conducted with a sample of 242 elderly people in Okharpauwa, Nepal to obtain prevalence of malnutrition. Differences in demographic and lifestyle factors between these who were malnourished, those at risk of malnourishment, and those who had adequate nutritional status were analyzed. The MNA tool was evaluated using receiver operating characteristic (ROC) curve analysis; sensitivity, specificity, and diagnostic accuracy were calculated. 111 males and 131 females, with a mean age of 69.8±7.4 years, participated in this study. The mean BMI of the participants was 21.4±3.9 kg/m2; the mean MNA score was 19.3±4.2. BMI was significantly correlated with the total MNA score (r = 0.58; p<0.001). The diagnostic accuracy, sensitivity and specificity of MNA were 81%, 86% and 67% respectively. Of the 242 elderly sampled, 24% were malnourished and 65% were at risk of malnutrition. Malnutrition was more prevalent among females (29%) than males (18%), and most prevalent among the marginalized Dalit ethnic group (40%). Elderly persons who were married and literate had better nutritional health than their counterparts. The MNA appears to be a valid and sensitive tool for

We investigate the crustal structure beneath five broadband seismic stations in the NW-SE trendingoval shaped Kashmir valley sandwiched between the Zanskar and the Pir Panjal ranges of thenorthwestern Himalaya. Three of these sites were located along the southwestern edge of the valley andthe other two adjoined the southeastern. Receiver Functions (RFs) at these sites were calculated usingthe iterative time domain deconvolution method and jointly inverted with surface wave dispersiondata to estimate the shear wave velocity structure beneath each station. To further test the results ofinversion, we applied forward modelling by dividing the crust beneath each station into 4-6homogeneous, isotropic layers. Moho depths were separately calculated at different piercing pointsfrom the inversion of only a few stacked receiver functions of high quality around each piercing point.These uncertainties were further reduced to ±2 km by trial forward modelling as Moho depths werevaried over a range of ±6 km in steps of 2 km and the synthetic receiver functions matched with theinverted ones. The final values were also found to be close to those independently estimated using theH-K stacks. The Moho depths on the eastern edge of the valley and at piercing points in itssouthwestern half are close to 55 km, but increase to about 58 km on the eastern edge, suggesting thathere, as in the central and Nepal Himalaya, the Indian plate dips northeastwards beneath the Himalaya.We also calculated the Vp/Vs ratio beneath these 5 stations which were found to lie between 1.7 and1.76, yielding a Poisson's ratio of ~0.25 which is characteristic of a felsic composition.

To analyse the impact of the medical colleges that have been set up within the last two decades by production of the doctors and the effect on the health of the people. SWOT (strength, weakness, opportunities and threats) analysis of medical education in Nepal has been done by reviewing medical manpower produced by the different institutions in the undergraduate and postgraduate (PG) categories, their registration with the Nepal Medical Council in terms of the existing health scenario of the country. Shows severe shortage of basic sciences teachers. In the clinical areas ophthalmic manpower and services provided are exemplary. There are shortages and shortcomings in all areas if standard health care is to be provided to the Nepalese. There is a long way to go to provide the expected educational and medical services to foreigners prepared to pay more to avail of this in Nepal.

First report of Lyme disease in Nepal.

Lyme disease is a tick-borne illness caused by the spirochete Borrelia burgdorferi and is widely reported in the USA, Central Europe, South East Asia and Latin America. Until recently, no scientific report regarding Lyme disease in Nepal had been published. A 32-year-old, previously healthy female visited the hospital with a history of joint pains, fatigue, neck stiffness, tingling sensation and headache. She was initially treated for typhoid fever, brucellosis and malaria, but did not show significant improvement. Doxycycline was prescribed empirically for 3 weeks for the treatment of suspected tick-borne illness. A two-tiered immunoglobulin laboratory testing confirmed Borrelia burgdorferi . She developed post-treatment Lyme disease syndrome after completion of antibiotic therapy. To the best of our knowledge, this is the first report of Lyme disease in Nepal and probably the first documented case of post-treatment Lyme disease syndrome in Asia. Lyme disease might have been overlooked in Nepal and, therefore, patients having clinical signs and symptoms similar to Lyme disease should not be disregarded in differential diagnosis.

Incidence Rate of Acute Encephalitis Syndrome without Specific Treatment in India and Nepal

Potharaju, Nagabhushana Rao

2012-01-01

Background: A performance target (PT) for the incidence rate (IR) of acute encephalitis syndrome (AES) was not defined by the World Health Organization (WHO) due to lack of data. There is no specific treatment for ~90% of the AES cases. Objectives: (1) To determine the IR of AES not having specific treatment (AESn) in two countries, India and Nepal. (2) To suggest the PT. Subjects and Methods: This was a record-based study of the entire population of India and Nepal from 1978 to 2011. The WHO definition was used for inclusion of cases. Cases that had specific treatment were excluded. IR was calculated per 100,000 population per annum. Forecast IR was generated from 2010 to 2013 using time-series analysis. Results: There were 165,461 cases from 1978 to 2011, of which 125,030 cases were from India and 40,431 were from Nepal. The mean IR of India was 0.42 (s 0.24) and that of Nepal was 5.23 (σ 3.03). IRs of 2010 and 2011 of India and that of 2011 of Nepal were closer to the mean IR rather than the forecast IR. IR of 2010 of Nepal was closer to the forecast IR. The forecast IR for India for 2012 was 0.49 (0.19-1.06), for 2013 was 0.42 (0.15-0.97) and for Nepal for both 2012 and 2013 was 5.62 (1.53-15.05). Conclusions: IRs were considerably different for India and Nepal. Using the current mean IR as PT for the next year was simple and practical. Using forecasting was complex and, less frequently, useful. PMID:23293439

Modern astronomy is a crowning achievement of human civilization which inspires teenagers to choose career in science and technology and is a stable of adult education. It is a unique and cost effective tool for furthering sustainable global development because of its technological, scientific and cultural dimensions which allow us to reach with the large portion of the community interact with children and inspire with our wonderful cosmos.Using astronomy to stimulate quality and inspiring education for disadvantaged children is an important goal of Nepal Astronomical Society (NASO) since its inception. NASO is carrying out various awareness activities on its own and in collaboration with national and international organizations like Central Department of Physics Tribhuvan University (TU), International astronomical Union (IAU), Department of Physics Prithvi Narayan Campus Pokhara, Nepal academy of science and technology (NAST), Global Hands on Universe (GHOU), EU- UNAWE and Pokhara Astronomical Society (PAS) to disseminate those activities for the school children and teachers in Nepal. Our experiences working with kids, students, teachers and public in the field of universe Awareness Activities for the school children to minimize the abstruse concept of astronomy through some practical approach and the project like Astronomy for the visually impaired students, Galileo Teacher Training program and International School for young astronomers (ISYA) outskirts will be explained which is believed to play vital role in promoting astronomy and space science activities in Nepal.

Impact and determinants of sex preference in Nepal.

Gender discrimination and son preference are key demographic features of South Asia and are well documented for India. However, gender bias and sex preference in Nepal have received little attention. 1996 Nepal Demographic and Health Survey data on ever-married women aged 15-49 who did not desire any more children were used to investigate levels of gender bias and sex preference. The level of contraceptive use and the total fertility rate in the absence of sex preference were estimated, and logistic regression was performed to analyze the association between socioeconomic and demographic variables and stopping childbearing after the birth of a son. Commonly used indicators of gender bias, such as sex ratio at birth and sex-specific immunization rates, do not suggest a high level of gender discrimination in Nepal. However, sex preference decreases contraceptive use by 24% and increases the total fertility rate by more than 6%. Women's contraceptive use, exposure to the media, parity, last birth interval, educational level and religion are linked to stopping childbearing after the birth of a boy, as is the ethnic makeup of the local area. The level of sex preference in Nepal is substantial. Sex preference is an important barrier to the increase of contraceptive use and decline of fertility in the country; its impact will be greater as desired family size declines.

Nepal is a country in which shallow landslide is a frequent phenomenon. Monsoon is the main triggering factor but anthropogenic influence is often significant too. Indeed, many infrastructures, such as roads or water pipes, are not built in a rigorous way because of a lack of funds and knowledge. In the present study we examine the technical, social and economic issues of landslide management for two sites in Nepal. The first site is located in Sanusiruwari VDC (Sindhupalchock district, central Nepal) and the second one in Namadi VDC (Ramecchap district, central Nepal). Both sites are affected by landslides induced by the construction of hydropower plants. These landslides may threaten the viability of the hydropower plants. At both sites the problems are quite similar, but the first site project is a private one and the second one is a public one implemented by the United Nations Development Programme (UNDP). For both sites, bioengineering methods using Vetiver (Vetyveria zizanioides) plantations is the main stabilization measure. To follow the progression of both landslides, fieldwork observations were conducted before and after the 2012 rainy season, including photogrammetric and distancemeter acquisitions. Main issues were discussed with communities and stakeholders of the hydropower projects through interviews and participatory risk mapping. Main issues include: lack of communication between the project managers and communities leading to conflict and the lack of maintenance of the bio-engineering sites, leading to less effective Vetiver growth and slope stabilization. Comparing the landslide management (technical, social and economic) of the two projects allows to point out some specific issues within an integrated risk perspective.

Many countries have weak disease surveillance and immunization systems. The elimination of polio creates an opportunity to use staff and assets from the polio eradication programme to control other vaccine-preventable diseases and improve disease surveillance and immunization systems. In 2003, the active surveillance system of Nepal's polio eradication programme began to report on measles and neonatal tetanus cases. Japanese encephalitis and rubella cases were added to the surveillance system in 2004. Staff from the programme aided the development and implementation of government immunization policies, helped launch vaccination campaigns, and trained government staff in reporting practices and vaccine management. Nepal eliminated indigenous polio in 2000, and controlled outbreaks caused by polio importations between 2005 and 2010. In 2014, the surveillance activities had expanded to 299 sites, with active surveillance for measles, rubella and neonatal tetanus, including weekly visits from 15 surveillance medical officers. Sentinel surveillance for Japanese encephalitis consisted of 132 sites. Since 2002, staff from the eradication programme have helped to introduce six new vaccines and helped to secure funding from Gavi, the Vaccine Alliance. Staff have also assisted in responding to other health events in the country. By expanding the activities of its polio eradication programme, Nepal has improved its surveillance and immunization systems and increased vaccination coverage of other vaccine-preventable diseases. Continued donor support, a close collaboration with the Expanded Programme on Immunization, and the retention of the polio eradication programme's skilled workforce were important for this expansion.

Climate change is a global issue in this century which has challenged the survival of living creatures affecting the life supporting systems of the earth: atmosphere, hydrosphere and lithosphere. Scientists have reached in a consensus that climate change is happening. The anthropogenic emission of greenhouse gases is responsible for global warming and therefore climate change. Climate change may directly or indirectly affect human health through a range of pathways related to temperature and precipitation. The aim of this article is to share knowledge on how climate change can affect public health in Nepal based on scientific evidence from global studies and experience gained locally. In this review attempt has been made to critically analyze the scientific studies as well as policy documents of Nepalese Government and shed light on public health impact of climate change in the context of Nepal. Detailed scientific study is recommended to discern impact of climate change on public health problems in Nepal.

2017-03-01

This paper focuses on the use of community-based early warning systems for flood resilience in Nepal. The first part of the work outlines the evolution and current status of these community-based systems, highlighting the limited lead times currently available for early warning. The second part of the paper focuses on the development of a robust operational flood forecasting methodology for use by the Nepal Department of Hydrology and Meteorology (DHM) to enhance early warning lead times. The methodology uses data-based physically interpretable time series models and data assimilation to generate probabilistic forecasts, which are presented in a simple visual tool. The approach is designed to work in situations of limited data availability with an emphasis on sustainability and appropriate technology. The successful application of the forecast methodology to the flood-prone Karnali River basin in western Nepal is outlined, increasing lead times from 2-3 to 7-8 h. The challenges faced in communicating probabilistic forecasts to the last mile of the existing community-based early warning systems across Nepal is discussed. The paper concludes with an assessment of the applicability of this approach in basins and countries beyond Karnali and Nepal and an overview of key lessons learnt from this initiative.

Population dynamics and environmental degradation in Nepal: an interpretation.

PubMed

Karki, Y B

1993-01-01

This paper examines the special problems that are faced by developing countries, specifically Nepal, which have to sustain increasing populations from a depleting natural resource base. Nepal is an example of a developing country where fertility is high and mortality is decreasing fast, resulting in a high rate of population growth. Nepal's rapid population growth has had a significant impact on natural resource depletion and consequently, environmental degradation. The case of Nepal demonstrates the difficulties confronting developing countries, which attempt practical implementation of the population policy guidelines set out in Agenda 21. Past and current population programs in this country have failed to address the population problem as multidimensional, and have failed to encourage grassroots participation. Economic stagnation and poverty encourage a large family size, and are delaying declines in fertility which subsequently leads to high land encroachment and fast depletion of natural resources like forests and water. The government needs to implement an integrated, multidimensional approach, which emphasizes literacy, education, lowering infant mortality, and providing contraceptives along with follow-ups. Finally, the greatest action must consist of fostering a higher rate of planned economic and social development that must be shown to have meaning for, and impact on the population in general.

HIV-AIDS in Nepal: the coming crisis.

PubMed

Seddon, D

1998-01-01

The number of officially reported cases of HIV infection and of AIDS in Nepal remains low in comparison with numbers in many other Asian countries. But Nepal's open border with India (where HIV infection rates are rapidly rising) and the high level of physical mobility within Nepal and abroad, associated with widespread labor migration and encouraged by the recent development of road transport, means that there is a real danger of a rapid spread of HIV within Nepal. The major means of infection is through heterosexual encounters involving male clients and female sex workers, but other sections of the population are also at risk from infection. Media attention has focused on female sex workers, particularly those who have worked in India, but the issue is far broader than this. Social and economic factors forcing or encouraging young men and women to seek employment away from home underlie the widespread growth of ¿the sex industry¿ and the ¿trafficking¿ of girls and young women. The state's capacity to respond effectively is limited, in part through lack of resources; international agencies are supporting local nongovernmental organizations in a variety of activities designed to ¿educate¿ and to ¿support¿ those at risk; but in the last analysis, it is the local communities from which young men and women migrate and to which they return that are obliged to find ways of coping. Sometimes these communities are supportive of the victims, sometimes not. The spread of HIV-AIDS is not just a ¿health¿ issue, but an issue of economic and social development, of gender relations and of human rights.

  The aim was to study the clinical characteristics of Duane's retraction syndrome (DRS) in Nepalese patients.   Medical records from 52 cases of DRS from May 2003 to April 2010 were retrospectively reviewed for age, gender, laterality and clinical characteristics. Forty-one case records (78.8 per cent) that had complete clinical findings were considered for further evaluation. Examination included visual acuity by Snellen chart, refraction, associated horizontal and vertical strabismus in primary gaze, upshoot and downshoot on attempted adduction, binocular vision assessed with the Worth four-dot test on adopted gaze and stereopsis examined with the Titmus stereo test.   DRS type I was the most common type observed in 73.2 per cent of cases, followed by DRS type II (14.6 per cent) and DRS type III (12.2 per cent). It was more common in female patients (58.5 per cent) than male patients (χ(2) = 4.6, df = 1, p = 0.03). DRS was more common in the left eye (68.3 per cent) than the right eye and unilaterally present in 95.1 per cent of subjects. In primary gaze, orthotropia (41.5 per cent) was more common than exotropia (34.1 per cent) and esotropia (24.4 per cent) and vertical strabismus was present in 24.4 per cent of subjects. Upshoot and downshoot on attempted adduction was seen in 14.6 and 9.8 per cent, respectively. Binocular single vision was present in 68.3 per cent of subjects by Worth four-dot test at near. Stereopsis of 3,000 seconds of arc was present in 9.8 per cent, 100 to 200 seconds of arc in 14.6 per cent and 40 to 60 seconds of arc in 43.9 per cent with the Titmus stereo test.   DRS is more common in female patients and the left eye.

Higher concentrations of ammonium (NH(4)-N) and iron (Fe) than a standard for drinking are typical characteristics of groundwater in the study area. To remove NH(4)-N and Fe, the drinking water supply system in this study consists of a series of treatment units (i.e., aeration and sedimentation, filtration, and chlorination); however, NH(4)-N in treated water is higher than a standard for drinking (i.e., <1.5 mg NH(4)-N/L). The objective of this study, therefore, is to develop an attached growth system containing a fiber carrier for reducing NH(4)-N concentration within a safe level in the treated water. To avoid the need of air supply for nitrification, groundwater was continuously dripped through the reactor. It made the system simple operation and energy efficient. Effects of reactor design (reactor length and carrier area) were studied to achieve a high NH(4)-N removal efficiency. In accordance with raw groundwater characteristics in the area, effects of low inorganic carbon (IC) and phosphate (PO(4)-P) and high Fe on the removal efficiency were also investigated. The results showed a significant increase in NH(4)-N removal efficiency with reactor length and carrier area. A low IC and PO(4)-P had no effect on NH(4)-N removal, whereas a high Fe decreased the efficiency significantly. The first 550 days operation of a pilot-scale reactor installed in the drinking water supply system showed a gradual increase in the efficiency, reaching to 95-100%, and stability in the performance even with increased flow rate from 210 to 860 L/day. The high efficiency of the present work was indicated because only less than 1 mg of NH(4)-N/L was left over in the treated water.

Determinants of skilled birth attendants for delivery in Nepal.

2010-01-01

This review is to explore the factors affecting the uptake of skilled birth attendants for delivery and the issues associated with women's role and choices of maternal health care service for delivery in Nepal. Literature was reviewed across the globe and discussed in a Nepalese context. Delivery by Skilled Birth Attendance serves as an indicator of progress towards reducing maternal mortality worldwide, the fifth Millennium Development Goal. Nepal has committed to reducing its maternal mortality by 75% by 2015 through ensuring accessibility to the availability and utilisation of skilled care at every birth. The literature suggests that several socio-economic, cultural and religious factors play a significant role in the use of Skilled Birth Attendance for delivery in Nepal. Availability of transportation and distance to the health facility; poor infrastructure and lack of services; availability and accessibility of the services; cost and convenience; staff shortages and attitudes; gender inequality; status of women in society; women's involvement in decision making; and women's autonomy and place of residence are significant contributing factors for uptake of Skilled Birth Attendance for delivery in Nepal. The review found more quantitative research studies exploring the determinants of utilisation of the maternal health services during pregnancy in Nepal than qualitative studies. Findings of quantitative research show that different social demographic, economic, socio-cultural and religious factors are responsible for the utilisation of maternal health services but very few studies discussed how and why these factors are responsible for utilisation of skilled birth attendants in pregnancy. It is suggested that there is need for more qualitative research to explore the women's role and choice regarding use of skilled birth attendants services and to find out how and why these factors are responsible for utilisation of skilled birth attendants for delivery

2009-06-01

To find out the prevalence of Staphylococcus aureus nosocomial infection and methicillin resistant S. aureus (MRSA), clinical samples from nosocomially infected patients were processed by following standard methodology in microbiology laboratory, Tribhuvan University Teaching Hospital, Kathmandu, Nepal. Of 149 S. aureus isolates, skin infection isolates contributed a major part 72.5% making nosocomial infection by S. aureus most prevalent in skin infection followed by lower respiratory tract infection 11.41% and urinary tract infection 8.7%. Overall MRSA prevalence was 45.0%. MRSA prevalence was 42.6% in skin infection, 82.3% in lower respiratory tract infection and 30.8% in urinary tract infection. MRSA infection was found associated with lower respiratory tract infection only. Highest occurrence of nosocomial infection was observed in female surgical ward, surgical out patient department, orthopedic ward, male surgical ward and maternity ward. MRSA isolation was high from lower respiratory tract of patients admitted in intensive care unit, coronary care unit, Sub-acute intensive care unit, intermediate coronary care unit, neurology ward and post-operative ward. Whereas methicillin sensitive S. aureus (MSSA) occurrence was higher in patients admitted in orthopedic, Surgical out patient department, and female surgical ward. The occurrence of MRSA did not differ with age but MRSA was found associated with male patients and MSSA was associated with female patients. Since MRSA prevalence was high, regular surveillance of MRSA and nosocomial infections should be done and universal precautions to control nosocomial infections should be followed.

Until now, an estimate quotes that 1100 healthcare facilities were damaged and over 100,000 livestock lost in the two earthquakes that occurred in April and May of 2015 in Nepal. Threats of infectious diseases, mostly zoonoses, could affect Nepal's economy, trade, and tourism, and reaching the targets of the United Nations Millennium Development Goals. Historically, outbreaks of infectious diseases, including zoonoses, were largely associated with the aftereffects of the earthquakes. It has been documented that zoonoses constitute 61% of all known infectious diseases. Therefore, the purpose of this communication was to examine the infectious disease outbreaks after earthquakes around the world and explore the risk assessment of the zoonoses threats reported in Nepal and highlight adopting One Health. Our summaries on reported zoonoses in Nepal have shown that parasitic zoonoses were predominant, but other infectious disease outbreaks can occur. The fragile public health infrastructure and inadequately trained public health personnel can accelerate the transmission of infections, mostly zoonoses, in the post impact phase of the earthquake in Nepal. Therefore, we believe that with the support of aid agencies, veterinarians and health professionals can team up to resolve the crisis under One Health.

Background Rabies is a vaccine-preventable viral zoonosis belonging to the group of neglected tropical diseases. Exposure to a rabid animal may result in a fatal acute encephalitis if effective post-exposure prophylaxis is not provided. Rabies occurs worldwide, but its burden is disproportionately high in developing countries, including Nepal. We aimed to summarize current knowledge on the epidemiology, impact and control of rabies in Nepal. Methods We performed a systematic review of international and national scientific literature and searched grey literature through the World Health Organization Digital Library and the library of the National Zoonoses and Food Hygiene Research Centre, Nepal, and through searching Google and Google Scholar. Further data on animal and human rabies were obtained from the relevant Nepalese government agencies. Finally, we surveyed the archives of a Nepalese daily to obtain qualitative information on rabies in Nepal. Findings So far, only little original research has been conducted on the epidemiology and impact of rabies in Nepal. Per year, rabies is reported to kill about 100 livestock and 10–100 humans, while about 1,000 livestock and 35,000 humans are reported to receive rabies post-exposure prophylaxis. However, these estimates are very likely to be serious underestimations of the true rabies burden. Significant progress has been made in the production of cell culture-based anti-rabies vaccine and rabies immunoglobulin, but availability and supply remain a matter of concern, especially in remote areas. Different state and non-state actors have initiated rabies control activities over the years, but efforts typically remained focalized, of short duration and not harmonized. Communication and coordination between veterinary and human health authorities is limited at present, further complicating rabies control in Nepal. Important research gaps include the reporting biases for both human and animal rabies, the ecology of stray

Communication and coordination between veterinary and human health authorities is limited at present, further complicating rabies control in Nepal. Important research gaps include the reporting biases for both human and animal rabies, the ecology of stray dog populations and the true

OBJECTIVES The aim of this paper is to evaluate the current status of the disease, the mechanism of infection, and pathogenesis, its zoonotic potential, diagnostic advances, treatment regimens, and the preventive measures that can be adopted in managing human brucellosis in under-developed countries such as Nepal. METHODS We performed a systematic review of all the available literture through Google Scholar, PubMed, Gideon Informatics, World Health Organization and other legitimate sources. Other secondary informations were collected from the government agencies such as department of livestock services and Ministry of Health. The obtained information was then re-analysed and summarized. RESULTS Few publications have addressed brucellosis in Nepal and most of those publications have focused on bovine brucellosis with sparse information available on brucellosis in humans and small ruminants. Brucella abortus is the most predominant causative agent followed by B. suis. B. abortus is predominant in cattle accounting for a substantial portion of bovine abortion in the country. Lack of awareness, unhealthy food habit, traditional husbandry practices, and a lack of surveillance and immunization have been the major factors in maintaining a vicious cycle of propagation of the disease in human and animals. Unfortunately, nothing has been done to identify the species of Brucella at the biovar level. CONCLUSIONS Although brucellosis has been reported to be endemic in Nepal, neither the distribution nor the economic and public health impact of this disease is well characterized. Robust and well-designed nationwide survey is warranted to assess the prevalence and distribution of disease in livestock and humans. Such data would facilitate the design of appropriate control programmes. PMID:27703129

Unsafe abortion is affecting a lot, in health, socio-economic and health care cost of many countries. Despite invention of simple technology and scientifically approved safe abortion methods, women and girls are still using unsafe abortion practices. Since 2002, Nepal has achieved remarkable progress in developing policies, guidelines, task shifting, training human resources and increasing access to services. However, more than half of abortion in Nepal are performed clandestinely by untrained or unapproved providers or induced by pregnant woman herself. Knowledge on legalization and availability of safe abortion service among women is still very poor. Stigma on abortion still persists among community people, service providers, managers, and policy makers. Access to safe abortion, especially in remote and rural areas, is still far behind as compared to their peers from urban areas. The existing law is not revised in the spirit of current Constitution of Nepal and rights-based approach. The existence of abortion stigma and the shifting of the government structure from unitary system to federalism in absence of a complete clarity on how the safe abortion service gets integrated into the local government structure might create challenge to sustain existing developments. There is, therefore, a need for all stakeholders to make a lot of efforts and allocate adequate resources to sustain current achievements and ensure improvements in creating a supportive social environment for women and girls so that they will be able to make informed decisions and access to safe abortion service in any circumstances.

Health professional mobility has increased in the recent years and is one of the public health concerns in the developing countries including Nepal. On the other hand, we can't ignore a positive shift of Nepali diaspora coming back to Nepal for some work related projects. The objective of this study was thus to estimate the number of Nepalese Diaspora and foreign expatriate those are coming to Nepal and explore the ways and process of their engagement in the health sector of Nepal. Mixed method was used. In total, 13 Key Informant Interviews were conducted at the central level along with record review from professional councils. Nepalese Diasporas mainly come through Diaspora Volunteering Organizations, Non Resident Nepali Association and personal connections to the place of their origin. Nepalese Diasporas have supported as health specialists, health camps and project organizers, trainer and hospital promoters, supplier of equipment including ambulances etc. The Nepalese Diasporas are unrecorded with professional organizations such as NMC and NHPC. As such the real status and results of support from Nepalese Diaspora are not known. Overall, 5,120 foreign medical professionals have served to Nepal through NMC followed by 739 nursing professionals through NNC and 189 paramedical staff through NHPC as of 2012. Systematic information on number and characteristics of the Nepalese Diaspora and their role in the health sector of Nepal is limited. The health professional bodies have some record systems but they lack uniformity and systematic process.

In April 2015, a major earthquake struck northern regions of Nepal affecting one-third of the population, and many suffered mental health problems. This study aimed to conduct a preliminary investigation of prevalence and feasibility of brief therapy for posttraumatic stress disorder (PTSD) among earthquake survivors. This is an exploratory cross-sectional study of prevalence and feasibility of brief trauma-focused therapy for PTSD among survivors 3 and 11 months after the earthquake in affected areas near Kathmandu. A team of local nonspecialist mental health volunteers was trained to identify survivors with PTSD using the PTSD checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (PCL-5) (cutoff score 38). They were trained to deliver either shortened versions of narrative exposure therapy (NET)-revised or group-based control-focused behavioral treatment (CFBT). Altogether, 333 survivors were surveyed (130 in July 2015 and 203 in March 2016) with PCL-5 as the screening instrument, using the cutoff score of 38 or more for diagnosing PTSD. A PTSD prevalence of 33% was noted in 2015 and 28.5% in 2016. This drop of 4.5% prevalence in the intervening 8 months suggests that a significant number of survivors are still suffering from PTSD. Most participants were female, aged 40 or above, married, and poorly educated. Compared to the brief (four sessions) individual NET-revised, a group-based CFBT was found more acceptable and affordable. PTSD is common following earthquake trauma, and if untreated, survivors continue to suffer for a long time. Management of PTSD should be included in future disaster management plans.

On April 25, 2015, a destructive MW 7.8 earthquake struck the capital of Nepal, Kathmandu, killing more than 8800 people and destroying numerous historical structures. We analyze six coseismic interferograms from several satellites (ALOS-2, Sentinel-1 A, and RADARSAT-2), as well as three-dimensional displacements at six GPS stations to investigate fault structure and slip distribution of the Gorkha earthquake. Using a layered crustal structure, the best-fit slip model shows that the preferred dip angle of the mainshock fault is 6 ± 3.5° and the major slip is concentrated within depths of 8-15 km. The maximum slip of 6.0 m occurs at a depth of 11 km, 70 km south east of the epicenter. The coseismic rupture extends 150 km eastward of the epicentre with a cumulative geodetic moment of 7.8 × 1020 Nm, equivalent to an earthquake of MW 7.84. We also investigate the MW 7.2 aftershock on 12 May 2015 using another three postseismic interferograms from ALOS2, RADARSAT-2, and Sentinel-1 A. The InSAR-based best-fit slip model of the largest aftershock implies that its major slip is next to the eastern lower end of the mainshock rupture with a similar maximum slip of 6 m at a depth of 13 km. This study generates various coseismic geodetic measurements to determine the source parameters of the MW 7.8 Gorkha earthquake and 12 May MW 7.2 afershock, providing an additional chance to understand the local fault structure and slip extent.

Upper Mustang in the Northern Himalayan range of Nepal is the home of brown bears (Ursusarctos). Low-plant biomass as a result of scanty rainfall in Upper Mustang is a reason for habitat overlap of humans and wild animals. Humans who enter into the wild to collect firewood and graze cattle are liable to wild animal attacks. Such attacks, especially by brown bears, are readily identified by the type of injuries. These are more commonly confined to head and neck regions. Cutting, gnawing and tearing by sharp teeth and claws produces specific pattern of injuries, which are devastating but seldom fatal. This article reports a rare case of brown bear injury inflicted upon a man from the Upper Mustang region in Nepal. © The Author(s) 2016.

What Caused the Winter Drought in Western Nepal during Recent Years?

Wang, S-Y; Yoon, Jin-Ho; Gillies, R.

Western Nepal has experienced consecutive and worsened winter drought conditions since 2000 culminating in a severe drought episode during 2008-2009. In this study, the meteorological conditons and a historical pespective of the winter droughts in western Nepal were analyzed using respectively instumental records and a paleoclimatic drought index. Althought decadal-scale drought conditions were found to be recurrent in the paleoclimate record, the severity of the recent decadal drought (since 2000) clearly stands out in the 700 years of record and, this is suggestive of potential anthropogenic influences in the recent decades. Meteorological diagnosis using atmospheric reanalysis in the recent decadesmore » revealed that (1) winter drought in western Nepal is linked to the Arctic Oscillation and its decadal variability, which initiates a tropospheric short-wave train across the Europe, Eurasia and South Asia, and that (2) the persistent warming of the Indian Ocean likely contributes to the suppression of rainfall through enhanced local Hadley circultion. It is therefore conceivable that the recent spells of decadal drought in Nepal drought are symptomatic of both natural variability and anthropogenic influences.« less

Background Demographic transition in Nepal, like in many developing countries, has resulted in a burgeoning elderly population whose health status is not currently monitored. One pillar of health is adequate nutrition. Yet, little is known about the nutritional health status of the elderly in Nepal. The financial, material, and personnel limitations in Nepal’s health delivery services necessitate health screening instruments that require minimal clinical staff and resources. To our knowledge, no such nutritional assessment tool has been validated in Nepal. Therefore, our aims are two-fold: To assess the nutritional status of the elderly population in one typical Nepali village, Okharpauwa, in Nuwakot District, Nepal; and concurrently, to validate the Mini Nutritional Assessment (MNA) tool. Methods A cross-sectional field study was conducted with a sample of 242 elderly people in Okharpauwa, Nepal to obtain prevalence of malnutrition. Differences in demographic and lifestyle factors between these who were malnourished, those at risk of malnourishment, and those who had adequate nutritional status were analyzed. The MNA tool was evaluated using receiver operating characteristic (ROC) curve analysis; sensitivity, specificity, and diagnostic accuracy were calculated. Results 111 males and 131 females, with a mean age of 69.8±7.4 years, participated in this study. The mean BMI of the participants was 21.4±3.9 kg/m2; the mean MNA score was 19.3±4.2. BMI was significantly correlated with the total MNA score (r = 0.58; p<0.001). The diagnostic accuracy, sensitivity and specificity of MNA were 81%, 86% and 67% respectively. Of the 242 elderly sampled, 24% were malnourished and 65% were at risk of malnutrition. Malnutrition was more prevalent among females (29%) than males (18%), and most prevalent among the marginalized Dalit ethnic group (40%). Elderly persons who were married and literate had better nutritional health than their counterparts. Conclusions The MNA

The objective of this study was to assess the migration intention of students enrolled in pre-registration nursing programs in Nepal, and to explore factors influencing this intention. Using an embedded mixed methods design, 799 nursing students were surveyed, followed by 12 semi-structured face-to-face interviews. The result showed that the majority (92.5%) expressed some intention to migrate, with three quarters of these listed furthering their study abroad as the primary reason. In the multiple regression analysis, those with lower professional identity, and those who reported nursing was not their first choice were likely to express migration intention. Interview data identified low salaries, unemployment, poor working conditions, insufficient postgraduate education, and a lack of professional autonomy in Nepal as reasons for their intention to migrate. Increasing opportunities for nurses to undertake postgraduate education in Nepal, promoting a positive image of nursing, and facilitating a supportive learning environment during undergraduate nursing education could help address the potential loss of nurses from Nepal.

In recent years, transport of emissions from the Indo-Gangetic Plains (IGP), which covers parts of Pakistan, Nepal, India, Bangladesh has increased. Ozone pre-cursors like methane, nitrogen oxides, volatile organic carbons, and carbon monoxide from diesel based vehicular emission, biofuel and biomass burning, agricultural activities dominate the total emissions from the IGP. Synoptic circulation patterns along with local weather systems transport pollutants from the IGP up the Himalayan valleys to the Tibetan plateau. After being emitted, these pollutants are photochemically converted into tropospheric ozone - a short-lived climate pollutant that can increase atmospheric warming, alter processes of cloud formation, and in turn, influence precipitation levels and reduce carbon absorptivity in plants leading to decline in crop yields. However, little is known about vertical profiles of ozone concentration on the southern slopes of the Himalaya. Vertical ozone profiles were sampled from December 18th, 2015 to January 8th, 2016 from Pokhara (28.23°N, 83.99°E, 827m asl), Nepal using ozonesondes. Pokhara is located about 30km south of the Annapurna Himalaya, thus providing an ideal location to profile vertical ozone concentration south of the Himalaya. We launched one, two or four ozonesondes per day to examine the vertical resolution of ozone south of the Himalaya for the first time, and to understand the contribution of tropospheric and stratospheric sources. Here we present results from the 37 ozonesonde launches from Pokhara to examine: (i) how emissions from the IGP contribute to the vertical resolution of ozone, and (ii) if Himalayan orography provides an efficient path for stratosphere-troposphere air mass exchange under dry conditions. Our results show no signals of stratospheric air mass exchange. The results indicate higher levels of ozone within the boundary layer and lower troposphere. These higher values in the lower troposphere during winter seasons may

The emergence of extensively drug-resistant tuberculosis (XDR-TB) has raised public health concern for global control of TB. Although molecular characterization of drug resistance-associated mutations in multidrug-resistant isolates in Nepal has been made, mutations in XDR isolates and their genotypes have not been reported previously. In this study, we identified and characterized 13 XDR Mycobacterium tuberculosis isolates from clinical isolates in Nepal. The most prevalent mutations involved in rifampicin, isoniazid, ofloxacin, and kanamycin/capreomycin resistance were Ser531Leu in rpoB gene (92.3%), Ser315Thr in katG gene (92.3%), Asp94Gly in gyrA gene (53.9%) and A1400G in rrs gene (61.5%), respectively. Spoligotyping and multilocus sequence typing revealed that 69% belonged to Beijing family, especially modern types. Further typing with 26-loci variable number of tandem repeats suggested the current spread of XDR M. tuberculosis. Our result highlights the need to reinforce the TB policy in Nepal with regard to control and detection strategies. Copyright © 2012 Elsevier Ltd. All rights reserved.

Revisiting global body politics in Nepal: A reflexive analysis.

PubMed

Harcourt, Wendy

2016-01-01

Using the example of a human rights training in Nepal, the author looks at global body politics in a reflexive piece on her engagement in development practices that translate western feminist ideas on gender inequality and empowerment via UN human rights policies into non-western contexts. It firsts look at postcolonial and critical literature on feminist engagement in gender and development processes including a discussion on the concept of global body politics before examining briefly the framing of gender-based violence in Nepal. The core of the paper is a reflexive analysis and interrogation of the training in Nepal in order to bring out the tensions and contradictions around western developmental, feminist and human rights discourses. The discussion looks at how difficult it is for feminist, human rights and developmental discourses and practices to unmoor themselves from the notion of the 'expert' and those who do the rights/work/righting rights training and those who are perennially seen as requiring training. The conclusion reflects on possibilities of other epistemic practices found in intercultural dialogues.

The most common building typologies in Nepal are reinforced concrete (RC) frame buildings with masonry infill walls, unreinforced masonry (URM) bearing wall buildings, and wood frame buildings (Figure 5-1). The RC frames with masonry infills are commonly constructed in urban and semi-urban areas. Most of these buildings are three to five stories high, and most privately owned buildings are non-engineered. High rise buildings (up to 17 stories high) are also found in Kathmandu, but their number is limited. Burnt clay bricks are widely used as masonry infill walls; external walls are generally one full brick thick (~ 230 mm), and internal walls are one half brick thick. URM bearing wall buildings are an obvious choice for the population in rural areas and the outskirts of cities, primarily to limit the material expenses. Such buildings are generally two to four stories high and constructed using burnt clay brick masonry or stone masonry with cement, lime, or mud mortar. In some of the older constructions, a different mortar known as Vajra (a mix of lime and brick dust) is also observed. These buildings have either wooden or reinforced concrete flooring. A hybrid type of construction also prevails in semi-urban and rural areas, where wood frames are used in the ground story front façade, and rest of the house is made of unreinforced masonry bearing walls. Wood frame houses (generally two to three stories high) are also observed in rural areas where the material for such construction is easily available.

We examined the prevalence of child maltreatment as measured by the level of physical (moderate to severe) and emotional abuse and child labor, and the associated household level determinants of child maltreatment in Nepal. We used a nationally representative data set from the fifth round of the Nepal Multiple Indicator Cluster Survey (the 2014 NMICS). The main independent variables were household level characteristics. Dependent variables included child experience of moderate to severe physical abuse, emotional abuse, and child labor (domestic work and economic activities). Bivariate analyses and logistic regressions were used to examine the associations between independent and dependent variables. The results showed that nearly half of the children (49.8%) had experienced moderate physical abuse, 21.5% experienced severe physical abuse, and 77.3% experienced emotional abuse. About 27% of the children had engaged in domestic work and 46.7% in various economic activities. At bivariate level, educational level of household's head and household wealth status had shown significant statistical association with child maltreatment (p<0.001). Results from multivariate logistic regressions showed that higher education levels and higher household wealth status protected children from moderate to severe physical abuse, emotional abuse and child labor. In general, child maltreatment is a neglected social issue in Nepal and the high rates of child maltreatment calls for mass awareness programs focusing on parents, and involving all stakeholders including governments, local, and international organizations.

Non-communicable diseases (NCDs, e.g. cardiovascular diseases, cancer, chronic respiratory diseases and diabetes mellitus) are the main causes of mortality and morbidity in developing countries, including Nepal. Nearly half of the deaths in Nepal are caused by NCDs. Nepal lacks adequate human resources to prevent and manage NCDs, but the skills and expertise of pharmacists in Nepal are underused. There is evidence from many countries that pharmacists can contribute substantially to the prevention and management NCD. We aim to describe the opportunities and challenges for pharmacists to prevent and manage NCDs in Nepal. Pharmacists can contribute by screening and monitoring NCDs; counseling on lifestyle; providing medication therapy management services; promoting public health; and providing other pharmaceutical services. Challenges to the implementation of some of these activities in the current context include inadequate training of pharmacists in NCD prevention and management, the cost of pharmaceutical services to patients and government, and the existing health care service delivery model. There is a need for health services research to determine how pharmacists can be best used to prevent and manage NCDs in Nepal. Copyright © 2015 Elsevier Inc. All rights reserved.

Background Stunting is a major public health problem that results from inadequate nutritional intake over a long period of time. Disasters have major implications in poor and vulnerable children. The aim of this study was, therefore, to assess the impact of disasters on child stunting in Nepal. Method A sample consisting of 2,111 children aged 6–59 months was obtained from the 2011 Nepal Demographic and Health Survey. We used bivariate and multivariate analyses to examine moderate and severe stunting against disaster, controlling for all possible confounders. Result Out of the total study sample, 43% were stunted (17.1% severely and 25.9% moderately). The final model, after adjusting for confounders, showed that epidemics have no impact on child stunting (adjusted odds ratio [OR] =1.14, 95% confidence interval [CI]: 0.66, 1.97 and adjusted OR =1.04, 95% CI: 0.66, 1.65 for severe and moderate stunting, respectively). Floods have impact on child stunting (adjusted OR =0.57, 95% CI: 0.31, 0.96 and adjusted OR =0.66, 95% CI: 0.41, 0.94 for severe and moderate stunting, respectively). However, children aged 6–11 months, nonvaccinated children, children of working women, children who live in mountainous areas, and children from the poorest households were more likely to be moderately stunted. Similarly, children aged 36–47 months, Dalit and other ethnic groups, children from rural settings, and children from the poorest households were more likely to be severely stunted. Conclusion This article illustrates the need to rethink about child stunting in Nepal. This study suggests need for further research, integration of disaster data in the Nepal Demography Health Survey, educational interventions, public awareness, promotion of vaccination, and equity in health service delivery.

Abortion was legalized in Nepal in 2002, following advocacy efforts highlighting high maternal mortality from unsafe abortion. We sought to assess whether legalization led to reductions in the most serious maternal health consequences of unsafe abortion. We conducted retrospective medical chart review of all gynecological cases presenting at four large public referral hospitals in Nepal. For the years 2001-2010, all cases of spontaneous and induced abortion complications were identified, abstracted, and coded to classify cases of serious infection, injury, and systemic complications. We used segmented Poisson and ordinary logistic regression to test for trend and risks of serious complications for three time periods: before implementation (2001-2003), early implementation (2004-2006), and later implementation (2007-2010). 23,493 cases of abortion complications were identified. A significant downward trend in the proportion of serious infection, injury, and systemic complications was observed for the later implementation period, along with a decline in the risk of serious complications (OR 0.7, 95% CI 0.64, 0.85). Reductions in sepsis occurred sooner, during early implementation (OR 0.6, 95% CI 0.47, 0.75). Over the study period, health care use and the population of reproductive aged women increased. Total fertility also declined by nearly half, despite relatively low contraceptive prevalence. Greater numbers of women likely obtained abortions and sought hospital care for complications following legalization, yet we observed a significant decline in the rate of serious abortion morbidity. The liberalization of abortion policy in Nepal has benefited women's health, and likely contributes to falling maternal mortality in the country. The steepest decline was observed after expansion of the safe abortion program to include midlevel providers, second trimester training, and medication abortion, highlighting the importance of concerted efforts to improve access.

Because treatment with third-generation cephalosporins is associated with slow clinical improvement and high relapse burden for enteric fever, whereas the fluoroquinolone gatifloxacin is associated with rapid fever clearance and low relapse burden, we postulated that gatifloxacin would be superior to the cephalosporin ceftriaxone in treating enteric fever. We did an open-label, randomised, controlled, superiority trial at two hospitals in the Kathmandu valley, Nepal. Eligible participants were children (aged 2-13 years) and adult (aged 14-45 years) with criteria for suspected enteric fever (body temperature ≥38·0°C for ≥4 days without a focus of infection). We randomly assigned eligible patients (1:1) without stratification to 7 days of either oral gatifloxacin (10 mg/kg per day) or intravenous ceftriaxone (60 mg/kg up to 2 g per day for patients aged 2-13 years, or 2 g per day for patients aged ≥14 years). The randomisation list was computer-generated using blocks of four and six. The primary outcome was a composite of treatment failure, defined as the occurrence of at least one of the following: fever clearance time of more than 7 days after treatment initiation; the need for rescue treatment on day 8; microbiological failure (ie, blood cultures positive for Salmonella enterica serotype Typhi, or Paratyphi A, B, or C) on day 8; or relapse or disease-related complications within 28 days of treatment initiation. We did the analyses in the modified intention-to-treat population, and subpopulations with either confirmed blood-culture positivity, or blood-culture negativity. The trial was powered to detect an increase of 20% in the risk of failure. This trial was registered at ClinicalTrials.gov, number NCT01421693, and is now closed. Between Sept 18, 2011, and July 14, 2014, we screened 725 patients for eligibility. On July 14, 2014, the trial was stopped early by the data safety and monitoring board because S Typhi strains with high-level resistance to

Neurocysticercosis is a major cause of epilepsy in countries where Taenia solium is endemic and the parasite is a major cause of food-borne disease globally. Pigs are the natural intermediate host involved in transmission of the parasite. T. solium is known to be endemic in Nepal, however there is limited reliable data about the prevalence of the disease in Nepal. The aim of this study was to determine accurately the prevalence of porcine cysticercosis in slaughter age pigs in an area of Nepal where pigs are known to be free-roaming. Pigs were obtained from the Udaypur Village Development Committee (VDC) and Hirminiya & Betahani VDC of the Banke district in Nepal. One hundred and ten animals of slaughter age (approximately 8-16 months old) were purchased, slaughtered and the heart, liver, brain and half the body skeletal musculature were sliced using hand knives and the number and viability of T. solium cysts determined. Thirty two of the 110 animals were found to harbour T. solium cysticerci (29%), of which 30 (27%) were found to have viable cysticerci (93% of the infected animals). This is one of the highest prevalences of porcine cysticercosis that has been reported to date from the results of necropsy on randomly selected animals. This study highlights a high rate of transmission of T. solium in the Banke District of Nepal. It encourages further investigation of human and porcine cysticercosis in Nepal, as well as implementation of efforts to reduce transmission of the parasite and the associated human disease.

Thapa, Gopal B.; Weber, Karl E.

1995-07-01

Contributing to the debate on the causes of Himalayan environmental degradation, the status and management of four watersheds in the Upper Pokhara Valley were studied using information available from land use analysis, household surveys conducted in 1989 and 1992, deliberations held with villagers, and field observations. Accordingly, areas under forests and grazing lands were found being depleted at relatively high rates between 1957 and 1978 due mainly to the government policy of increasing national revenue by expansion of agricultural lands, nationalization of forests, steadily growing population, and dwindling household economy. Despite the steady growth of population, this process had remarkably slackened since 1978, owing primarily to remaining forests being located in very, steep slopes and implementation of the community forestry program. Forests with relatively sparase tree density, however, and grazing lands in the vicinity of settlements have been undergoing degradation due to fuelwood and fodder collection and livestock grazing. In many instances, this is aggravated by weak resource management institutions. Being particularly aware of the economic implication of land degradation, farmers have adopted assorted land management practices. Still a substantial proportion of bari lands in the hill slopes is vulnerable to accelerating degradation, as the arable cropping system is being practiced there as well. The perpetuation of the local subsistence economy is certain to lead, to a further deterioration of the socioeconomic and environmental conditions of watersheds. To facilitate environmental conservation and ecorestructuring for sustainable development, a broad watershed management strategy is outlined with focus on alleviating pressure on natural resources.

2016-04-01

On April 25, 2015 a Mw 7.8 earthquake occurred 80 km to the northwest of Kathmandu (Nepal). The largest aftershock, occurred on May 12, 2015, was the Mw 7.3 Nepal earthquake (SE of Zham, China), 80 km to the east of Kathmandu. . The earthquakes killed ~9000 people and severely damaged a 10,000 sqkm region in Nepal and neighboring countries. Several thousands of landslides have been triggered during the event, causing widespread damages to mountain villages and the evacuation of thousands of people. Rasuwa was one of the most damaged districts. This contribution describes landslide hazard analysis of the Saramthali, Yarsa and Bhorle VDCs (122 km2, Rasuwa district). Hazard is expressed in terms of qualitative classes (low, medium, high), through a simple matrix approach that combines frequency classes and magnitude classes. The hazard analysis is based primarily on the experience gained during a field survey conducted in September 2014. During the survey, local knowledge has been systematically exploited through interviews with local people that have experienced the earthquake and the coseismic landslides. People helped us to recognize fractures and active deformations, and allowed to reconstruct a correct chronicle of landslide events, in order to assign the landslide events to the first shock, the second shock, or the post-earthquake 2015 monsoon. The field experience was complemented with a standard analysis of the relationship between potential controlling factors and the distribution of landslides reported in Kargel et al (2016). This analysis allowed recognizing the most important controlling factor. This information was integrated with the field observations to verify the mapped units and to complete the mapping in area not accessible for field activity. Finally, the work was completed with the analysis and the use of a detailed landslide inventory produced by the University of Milano Bicocca that covers most of the area affected by coseismic landslides in

Dengue is an emerging disease in Nepal and was first observed as an outbreak in nine lowland districts in 2006. In 2010, however, a large epidemic of dengue occurred with 4,529 suspected and 917 serologically-confirmed cases and five deaths reported in government hospitals in Nepal. The collection of demographic information was performed along with an entomological survey and clinical evaluation of the patients. A total of 280 serum samples were collected from suspected dengue patients. These samples were subjected to routine laboratory investigations and IgM-capture ELISA for dengue serological identification, and 160 acute serum samples were used for virus isolation, RT-PCR, sequencing and phylogenetic analysis. The results showed that affected patients were predominately adults, and that 10% of the cases were classified as dengue haemorrhagic fever/ dengue shock syndrome. The genetic characterization of dengue viruses isolated from patients in four major outbreak areas of Nepal suggests that the DENV-1 strain was responsible for the 2010 epidemic. Entomological studies identified Aedes aegypti in all epidemic areas. All viruses belonged to a monophyletic single clade which is phylogenetically close to Indian viruses. The dengue epidemic started in the lowlands and expanded to the highland areas. To our knowledge, this is the first dengue isolation and genetic characterization reported from Nepal.

Challenging gender roles through STEM education in Nepal

NASA Astrophysics Data System (ADS)

Wallenius, Todd J.

Science, Technology, Engineering, Mathematics (STEM) education programs are currently being introduced and expanded across "developing" nations. STEM programs often conflict with hegemonic gender norms, for example by targeting girls and women in male dominated societies. However, given the cultural complexity of STEM for girls, implementing educators are rarely asked their point of view on programs from abroad. This study explored the perceptions of educators in Nepal who participated in the Girls Get STEM Skills (GGSS) program, a program funded through the U.S. Department of State for 2015/2016. The 8-month program reached 254 girls across three government schools and included the donation of 30 laptops. In August, 2016, the researcher conducted one-on-one interviews and focus groups with 18 participants at GGSS school sites in Pokhara, Nepal. Qualitative data was gathered on educators' perceptions of teacher roles, Nepal as a developing nation, gender imbalance in STEM, and the GGSS curriculum. The study argues that educators viewed educational topics through the lens of bikas, the Nepali word for development. This suggests that the principal impact of STEM programs--as part of larger development initiatives--may be the creation and reinforcement of new social meanings rather than the tangible impacts of the projects themselves.

Crossing the roof of the world: Trade in medicinal plants from Nepal to China.

Trade in medicinal and aromatic plants (MAPs) between Nepal and China has taken place for centuries along the Tibetan border. While there is anecdotal evidence that economic development in China over the past decades, coupled with regional infrastructure development and increasing market integration, has substantially changed this trade, there are no current published studies investigating this, e.g. in terms of species and market structure. This knowledge gap impedes the development of public interventions, e.g. in support of sustainable trade. The primary objective of this study is to provide the first informative insights into the Nepal-China trade in MAPs, with particular emphasis on the value chain in Tibet. Data was collected from December 2015 to August 2016 in Nepal and Tibet. The data collection included standardized questionnaires to understand and map the value chain of MAPs, including the actors involved and key governance issues. Data was collected from Katmandu-based MAPs wholesalers exporting from Nepal to China, (n = 6) and with regional wholesalers (n = 40) based in Tibet. The questionnaires contained quantitative and qualitative components focusing on key elements of the MAPs value chain, e.g. the traded species and their values. This was augmented with qualitative interviews with Lhasa-based processors (n = 4) and government officials (n = 12) working in border controls, customs, and/or drug administration. We also collected official statistics on the Nepal-China MAPs trade and conducted a workshop in Lhasa with traders and government officials to discuss the nature of the Nepal-China MAPs trade. The Nepal-China MAPs trade boomed after 2011 when the value of traded plants increased more than nine-fold. This rapid increase reflected both a broader species composition and higher unit prices in response to increasing demand from China. The trade expansion was also driven by increasing demand in China and facilitated by improved

Strong sustainability in Nepal: A structural economics approach

NASA Astrophysics Data System (ADS)

Devkota, Surendra R.

This dissertation analyzes the sustainability of the economy of Nepal. The main empirical question addressed is whether the Tenth Plan of Nepal (2002--2007) will meet its projected economic output goal and achieve its primary goal of reducing poverty. To this end, economic growth scenarios are examined in terms of availability of energy demand and supply, and income disparity among different households. The structure of the Nepali economy is examined using a Leontief input-output table, a Ghosian supply-side input-output table, and a social accounting matrix for the year 1999. Based on the input-output analysis of energy demand and supply for the 10th Plan, it is unlikely that energy requirements of the projected output will be met, unless some extra sources of energy are developed. Households need to switch their energy use from fuel wood/biomass to other alternatives. In order to meet the target of the Plan vis-a-vis energy demand or supply, a few policy measures are urgently needed, though some of these options require many years to develop. Household income inequality and distribution is examined through the SAM multipliers; namely aggregate, transfer, open-loop, and closed-loop multipliers. The investment-income multiplier scenarios for the 10th Plan indicate that the nominal income of households may increase due to the increased investment, which will not necessarily improve the bottom deciles households, particularly socio-economically deprived households. Economic growth in Nepal during the past fifty years demonstrates that the modernization model is unsuccessful. Economic growth occurred at some centers at the cost of periphery. A huge regional disparity has developed between hills and plains, east and west, city and rural areas. Nepal's persistent poverty indicates a failure of modernization theory. The Tenth Plan would be another continuation of a failed legacy, unless social and natural endowments are considered for sustainability. Nepal could be an

Tuberculosis (TB) caused by Mycobacterium tuberculosis (MTB) poses a major public health problem in Nepal. Although it has been reported as one of the dominant genotypes of MTB in Nepal, little information on the Central Asian Strain (CAS) family is available, especially isolates related to multidrug resistance (MDR) cases. This study aimed to elucidate the genetic and epidemiological characteristics of MDR CAS isolates in Nepal. A total of 145 MDR CAS isolates collected in Nepal from 2008 to 2013 were characterized by spoligotyping, mycobacterial interspersed repetitive unit-variable number tandem repeat (MIRU-VNTR) analysis, and drug resistance-associated gene sequencing. Spoligotyping analysis showed CAS1_Delhi SIT26 as predominant (60/145, 41.4%). However, by combining spoligotyping and MIRU-VNTR typing, it was possible to successfully discriminate all 145 isolates into 116 different types including 18 clusters with 47 isolates (clustering rate 32.4%). About a half of these clustered isolates shared the same genetic and geographical characteristics with other isolates in each cluster, and some of them shared rare point mutations in rpoB that are thought to be associated with rifampicin resistance. Although the data obtained show little evidence that large outbreaks of MDR-TB caused by the CAS family have occurred in Nepal, they strongly suggest several MDR-MTB transmission cases.

Using near-fault strong motions from Nepal Mw7.8 earthquake at KATNP station in the city center of Kathmandu, velocity-pulse and non-stationary characteristics of the strong motions are shown, and the reason and potential effect on earthquake damage for intense non-stationary characteristics of near fault velocity-pulse strong motions are mainly studied. The observed strong ground motions of main shock were collected from KATNP station located in 76 kilometers south-east away from epicenter along with forward direction of the rupture fault at an inter-montane basin of the Himalaya. Large velocity pulse show the period of velocity pulse reach up to 6.6s and peak ground velocity of the pulse ground motion is 120 cm/s. Compared with the median spectral acceleration value of NGA prediction equation, significant long-period amplification effect due to velocity pulse is detected at period more than 3.2s. Wavelet analysis shows that the two horizontal component of ground motion is intensely concentration of energy in a short time range of 25-38s and period range of 4-8s. The maximum wavelet-coefficient of horizontal component is 2455, which is about four time of vertical component of strong ground motion. On the perspective of this study, large velocity pulses are identified from two orthogonal components using wavelet method. Intense non-stationary characteristics amplitude and frequency content are mainly caused by site conditions and fault rupture mechanism, which will help to understand the damage evaluation and serve local seismic design.

The second half of the twentieth century has witnessed a tremendous development in the field of astronomy and space exploration. The large telescope both on the land and in the orbit, using the whole range of the electromagnetic spectra from radio waves to gamma rays are extending their range of exploration, right to the edge of the observable universe, and making astounding discoveries in the process. Many large international telescope facilities and global plans are accessible to all astronomers throughout the world, providing an inexpensive entry to cutting- edge international research for developing countries.Nepal is a mountainous country it has a wide range of climatic and altitude variations which varies from an elevation of 200 meter to ≥ 4000 meter. The average temperature varies from ≥ 25 o C to ≤ 0 to 5oC. Because of these diverse weather and climatic variation there is the potential for the establishment of sophisticated observatory/ data centre and link with each other. So, the future possible opportunity of astronomy in Nepal will be discussed. Besides Education and Research activities conducted in Tribhuvan University, Nepal under the support of International Astronomical Union (IAU) will also be highlighted. The importance brought by those two workshops conducted on data simulation supported by IAU under TF1 will also be discussed which is believed to play a vital role for the promotion and development of astronomy and astrophysics in developing countries.

Although abortion has been legal under broad criteria in Nepal since 2002, a significant proportion of women continue to obtain illegal, unsafe abortions, and no national estimates exist of the incidence of safe and unsafe abortions. Data were collected in 2014 from a nationally representative sample of 386 facilities that provide legal abortions or postabortion care and a survey of 134 health professionals knowledgeable about abortion service provision. Facility caseloads and indirect estimation techniques were used to calculate the national and regional incidence of legal and illegal abortion. National and regional levels of abortion complications and unintended pregnancy were also estimated. In 2014, women in Nepal had 323,100 abortions, of which 137,000 were legal, and 63,200 women were treated for abortion complications. The abortion rate was 42 per 1,000 women aged 15-49, and the abortion ratio was 56 per 100 live births. The abortion rate in the Central region (59 per 1,000) was substantially higher than the national average. Overall, 50% of pregnancies were unintended, and the unintended pregnancy rate was 68 per 1,000 women of reproductive age. Despite legalization of abortion and expansion of services in Nepal, unsafe abortion is still common and exacts a heavy toll on women. Programs and policies to reduce rates of unintended pregnancy and unsafe abortion, increase access to high-quality contraceptive care and expand safe abortion services are warranted.

Emigration from Nepal: some major issues.

PubMed

Singh, M L

1997-07-01

This study examined emigration from Nepal during 1952-91. Data were obtained from census records decennially. Records indicate that the volume of emigration amounted to about 2.39% of total population in 1952-53, and 3.58% in 1991. The level of emigration rose from 198,120 persons to 658,290. Emigrants are persons who were absent from their home for more than 6 months due to tourism, pilgrimage, business trips, studies, employment, or permanent migration. Most emigrants return home after several months or years. A recent survey finds that 14.1% returned after more than 5 years. The Nepal model of migration is different from conventional or Marxist models. For example, landlessness or near landlessness are not the primary reasons for migration. The recent emigration to Arab countries is driven by the desire for better income. Emigrants pay handsomely to go abroad for work (Rs. 85,000). Nepalese emigrate to Australia and the US for a better income and a better life. The proportion of female emigrants was 6.23% of total emigrants to Arab countries, and 16.2% to India. 31% of emigrants were females who emigrated to North America, and 29% emigrated to European countries. Emigrants to Arab countries were likely to return home. Emigrants to North America and Europe were likely to be permanent migrants. The author prefers Mellassoux's (1981) model that says that Nepal is losing manpower during their most productive years. Remittances do not offset the loss. Government costs are incurred for supporting education abroad, benefits in old age and for youth, and the spread of sexually transmitted diseases.

Influenza is one of the public health burdens in Nepal and its epidemiology is not clearly understood. The objective of this study was to explore the molecular epidemiology and the antigenic characteristics of the circulating influenza viruses in Nepal. A total of 1495 throat swab specimens were collected from January to December, 2014. Real time PCR assay was used for identification of influenza virus types and subtypes. Ten percent of the positive specimens were randomly selected and inoculated onto Madin-Darby Canine Kidney Epithelial cells (MDCK) for influenza virus isolation. All viruses were characterized by the hemagglutination inhibition (HI) assay. Influenza viruses were detected in 421/1495 (28.2%) specimens. Among positive cases, influenza A virus was detected in 301/421 (71.5%); of which 120 (39.9%) were influenza A/H1N1 pdm09 and 181 (60.1%) were influenza A/H3 subtype. Influenza B viruses were detected in 119/421 (28.3%) specimens. Influenza A/H1N1 pdm09, A/H3 and B viruses isolated in Nepal were antigenically similar to the vaccine strain influenza A/California/07/2009(H1N1pdm09), A/Texas/50/2012(H3N2), A/New York/39/2012(H3N2) and B/Massachusetts/2/2012, respectively. Influenza viruses were reported year-round in different geographical regions of Nepal which was similar to other tropical countries. The circulating influenza virus type and subtypes of Nepal were similar to vaccine candidate virus which could be prevented by currently used influenza vaccine.

Flood Induced Disasters and Stakeholder Involvement to Implement Integrated Food Management in Nepal

Nepal, a landlocked country in South Asia covers an area of 147, 181 square kilometers. Its elevation ranges from 61m as the lowest to 8848m, the highest peak Everest in the world. More than 80% of the annual rainfall occurs in the monsoon season from June to September. Thus, due to the intense rainfall that occurs within a short period, monsoon acts as the biggest cause for the occurrence of different disastrous events including flood. Beyond it, Nepal lies at the center and southern edge of Hindu-Kush Himalayan (HKH) region, which is the youngest geological formation in the world. Hence, floods and landslides are common in this region. In Nepal, from the records of 1971-2010, floods and landslides are the second biggest cause for casualties after epidemics. Hawaii based Center of Excellence in disaster management and humanitarian assistance in 2015 has declared Nepal as 30th vulnerable country from the aspect of floods. According to WMO definition, integrated flood management (IFM) is a process of promoting an integrated rather than a fragmented approach to flood management, integrating land and water resource development in a river basin within the context of integrated water resources management (IWRM), with the aim of maximizing the net benefits from flood plains while minimizing loss of life from flooding. That is the reason why the IFM is one of the important countermeasures to be implemented in Nepal to reduce the adverse effects of floods. This study emphasizes on the existing conditions along with the challenges of IFM with respect to stakeholder involvement in the context of Nepal. It can be assured that all the highlighted issues coming out from this study will be highly valuable to policy makers, implementing agencies along with scientific and local communities to enhance IFM works in the nation for the benefits of societies.

Lake deposits record evidence of large post-1505 AD earthquakes in western Nepal

According to historical records, the last large earthquake that ruptured the Main Frontal Thrust (MFT) in western Nepal occurred in 1505 AD. Since then, no evidence of other large earthquakes has been found in historical records or geological archives. In view of the catastrophic consequences to millions of inhabitants of Nepal and northern India, intense efforts currently focus on improving our understanding of past earthquake activity and complement the historical data on Himalayan earthquakes. Here we report a new record, based on earthquake-triggered turbidites in lakes. We use lake sediment records from Lake Rara, western Nepal, to reconstruct the occurrence of seismic events. The sediment cores were studied using a multi-proxy approach combining radiocarbon and 210Pb chronologies, physical properties (X-ray computerized axial tomography scan, Geotek multi-sensor core logger), high-resolution grain size, inorganic geochemistry (major elements by ITRAX XRF core scanning) and bulk organic geochemistry (C, N concentrations and stable isotopes). We identified several sequences of dense and layered fine sand mainly composed of mica, which we interpret as earthquake-triggered turbidites. Our results suggest the presence of a synchronous event between the two lake sites correlated with the well-known 1505 AD earthquake. In addition, our sediment records reveal five earthquake-triggered turbidites younger than the 1505 AD event. By comparison with historical archives, we relate one of those to the 1833 AD MFT rupture. The others may reflect successive ruptures of the Western Nepal Fault System. Our study sheds light on events that have not been recorded in historical chronicles. Those five MMI>7 earthquakes permit addressing the problem of missing slip on the MFT in western Nepal and reevaluating the risk of a large earthquake affecting western Nepal and North India.

Ecological and socio-demographic differences in maternal care services in Nepal

Background. Nepal is set to achieve MDG-5 goals by end of 2015. However, maternal health parameters will remain way below those of developed countries. This study was conducted to assess the factors contributing to utilization of ANC and safe delivery services with the aim of furthering overall maternal health parameters in Nepal. Material and Methods. Using survey data from the Nepal Demographic and Health Survey 2011, socio-economic and demographic factors associated with the utilization of ANC and safe delivery services among women aged 15–49 years who gave births during the last three years preceding the survey are examined. Data was segregated into three ecological zones: Mountain, Hill and Terai zones for univariate analyses. Data from all three zones was then pooled for univariate and multivariate logistic regression analyses of Antenatal Care and Safe Delivery services in Nepal. Results and Conclusion. The analyses show that rural place of residence is at a disadvantage in receiving ANC (OR, 0.8; 95% CI [0.7–0.9]) and ensuring safe delivery (OR, 0.6; 95% CI [0.5–0.7]). Woman’s education, husband’s education and wealth quintile are significant factors in ensuring ANC and safe delivery services. Further, the analyses show that Budh/Muslim/Kirat/Christians are at a significant disadvantage in ensuring safe delivery (OR, 0.8; 95% CI [0.7–0.9]) as compared with Hindus. Though ecological zones lost their significance in receiving ANC, women in the Terai region are at a significant advantage in ensuring safe delivery (OR, 1.7; 95% CI [1.2–2.1]). Recommendation. Segregated targets should be set for the different ecological zones for further improvement in maternal mortality rates in Nepal. PMID:26355429

Simulating the Snow Water Equivalent and its changing pattern over Nepal

Snow fall in the Himalayan region is one of the primary sources of fresh water, which accounts around 10% of total precipitation of Nepal. Snow water is an intricate variable in terms of its global and regional estimates whose complexity is favored by spatial variability linked with rugged topography. The study is primarily focused on simulation of Snow Water Equivalent (SWE) by the use of a macroscale hydrologic model, Variable Infiltration Capacity (VIC). As whole Nepal including its Himalayas lies under the catchment of Ganga River in India, contributing at least 40% of annual discharge of Ganges, this model was run in the entire watershed that covers part of Tibet and Bangladesh as well. Meteorological inputs for 29 years (1979-2007) are drawn from ERA-INTERIM and APHRODITE dataset for horizontal resolution of 0.25 degrees. The analysis was performed to study temporal variability of SWE in the Himalayan region of Nepal. The model was calibrated by observed stream flows of the tributaries of the Gandaki River in Nepal which ultimately feeds river Ganga. Further, the simulated SWE is used to estimate stream flow in this river basin. Since Nepal has a greater snow cover accumulation in monsoon season than in winter at high altitudes, seasonality fluctuations in SWE affecting the stream flows are known. The model provided fair estimates of SWE and stream flow as per statistical analysis. Stream flows are known to be sensitive to the changes in snow water that can bring a negative impact on power generation in a country which has huge hydroelectric potential. In addition, our results on simulated SWE in second largest snow-fed catchment of the country will be helpful for reservoir management, flood forecasting and other water resource management issues.

The purpose of this study was to identify predictors of oral hygiene behaviour (OHB) based on the Theory of Planned Behaviour (TPB) among dental care seekers in two cultural different regions: the Caribbean (Aruba/Bonaire) and Nepal. In addition, measures of oral health knowledge (OHK) and the expected social outcomes of having healthy teeth (ESO) were investigated. The main effects of the predictors as well as their interactions with region (Caribbean vs. Nepal) were examined. The interaction term contributed significantly to the amount of explained variance. In the Caribbean, OHB was determined by Attitude and Social Norms, and in Nepal by Perceived Behaviour Control and ESO. On the basis of these findings, quite different oral health care interventions are called for in developing and underdeveloped countries. © 2011 FDI World Dental Federation.

Valley-dependent band structure and valley polarization in periodically modulated graphene

NASA Astrophysics Data System (ADS)

Lu, Wei-Tao

2016-08-01

The valley-dependent energy band and transport property of graphene under a periodic magnetic-strained field are studied, where the time-reversal symmetry is broken and the valley degeneracy is lifted. The considered superlattice is composed of two different barriers, providing more degrees of freedom for engineering the electronic structure. The electrons near the K and K' valleys are dominated by different effective superlattices. It is found that the energy bands for both valleys are symmetric with respect to ky=-(AM+ξ AS) /4 under the symmetric superlattices. More finite-energy Dirac points, more prominent collimation behavior, and new crossing points are found for K' valley. The degenerate miniband near the K valley splits into two subminibands and produces a new band gap under the asymmetric superlattices. The velocity for the K' valley is greatly renormalized compared with the K valley, and so we can achieve a finite velocity for the K valley while the velocity for the K' valley is zero. Especially, the miniband and band gap could be manipulated independently, leading to an increase of the conductance. The characteristics of the band structure are reflected in the transmission spectra. The Dirac points and the crossing points appear as pronounced peaks in transmission. A remarkable valley polarization is obtained which is robust to the disorder and can be controlled by the strain, the period, and the voltage.

Nepal boarders India and China and all three countries lie within the Central Asian Flyway for migratory birds. Novel influenza A H7N9 caused human fatalities in China in 2013. Subclinical infections of influenza A H7N9 in birds and the potential for virus dispersal by migratory birds prompted this study to assess avian H7N9 viral intrusion into Nepal. Surveillance of influenza A virus in migratory birds was implemented in early 2014 with assistance from the Food and Agricultural Organization (FAO). Of 1811 environmental fecal samples collected from seven wetland migratory bird roosting areas, influenza A H9N2 was found in one sample from a ruddy shelduck in Koshi Tappu Wildlife Reserve located in southern Nepal. Avian H7N9 and other highly pathogenic avian influenza viruses were not detected. This study provides baseline data on the status of avian influenza virus in migratory bird populations in Nepal.

Context: In April 2015, a major earthquake struck northern regions of Nepal affecting one-third of the population, and many suffered mental health problems. Aims: This study aimed to conduct a preliminary investigation of prevalence and feasibility of brief therapy for posttraumatic stress disorder (PTSD) among earthquake survivors. Settings and Design: This is an exploratory cross-sectional study of prevalence and feasibility of brief trauma-focused therapy for PTSD among survivors 3 and 11 months after the earthquake in affected areas near Kathmandu. Methodology: A team of local nonspecialist mental health volunteers was trained to identify survivors with PTSD using the PTSD checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (PCL-5) (cutoff score 38). They were trained to deliver either shortened versions of narrative exposure therapy (NET)-revised or group-based control-focused behavioral treatment (CFBT). Results: Altogether, 333 survivors were surveyed (130 in July 2015 and 203 in March 2016) with PCL-5 as the screening instrument, using the cutoff score of 38 or more for diagnosing PTSD. A PTSD prevalence of 33% was noted in 2015 and 28.5% in 2016. This drop of 4.5% prevalence in the intervening 8 months suggests that a significant number of survivors are still suffering from PTSD. Most participants were female, aged 40 or above, married, and poorly educated. Compared to the brief (four sessions) individual NET-revised, a group-based CFBT was found more acceptable and affordable. Conclusions: PTSD is common following earthquake trauma, and if untreated, survivors continue to suffer for a long time. Management of PTSD should be included in future disaster management plans.

Glacier mass balance variability has an implication for the regional water resources and it helps to understand the response of glacier to climate change in the Himalayan region. Several mass balance studies have been started in the Himalayan region since 1970s, but they are characterized by frequent temporal gaps and a poor spatial representatively. This study aims at bridging the temporal gaps in a long term mass balance series of the Rikha Samba glacier (5383 - 6475 m a.s.l.), a benchmark glacier located in the Hidden Valley, Mustang, Nepal. The ERA Interim reanalysis data for the period 2011-2015 is calibrated with the observed meteorological variables from an AWS installed near the glacier terminus. We apply an energy mass balance model, validated with the available in-situ measurements for the years 1998 and 2011-2015. The results show that the glacier is shrinking at a moderate negative mass balance rate for the period 1995 to 2015 and the high altitude location of Rikha Samba also prevents a bigger mass loss compared to other small Himalayan glaciers. Precipitation from July to January and the mean air temperature from June to October are the most influential climatic parameters of the annual mass balance variability of Rikha Samba glacier.

The Himalayas are a global hotspot for bird diversity with a large number of threatened species, but little is known about seasonal changes in bird communities along elevational gradients in this region. We studied the seasonality of bird diversity in six valleys of the Central Himalayas, Nepal. Using 318 plots with a 50 m radius, located from 2200 to 3800 m a.s.l., and repeated sampling during different seasons (mainly pre-monsoon, monsoon, and post-monsoon), we analyzed 3642 occurrences of 178 species. Birds classified in the literature as resident were more species-rich than migratory birds (140 vs. 38 species). In all six valleys and within the studied elevation range, species richness of all birds showed a peak at mid-elevation levels of 2600 or 3000 m a.s.l. Similar patterns were found for the most species-rich feeding guilds of insectivores (96 species) and omnivores (24 species), whereas the species richness of herbivores (37 species including frugivores) increased towards higher elevations. Among these feeding guilds, only species richness of insectivores showed pronounced seasonal changes with higher species numbers during post-monsoon season. Similarly, individual bird species showed distinct spatio-temporal distribution patterns, with transitions from species dominated by elevational differences to those characterized by strong seasonal changes. In an era of climate change, the results demonstrate that individual bird species as well as feeding guilds might greatly differ in their responses to climate warming and changes in the seasonality of the precipitation regime, two aspects of climate change which should not be analyzed independently.

The 2017 monsoon in Nepal was normal until mid-August 2017 when a low pressure system that formed parallel to the foothills of the Churia range brought significant amount of rain in the southern Terai belt. Rivers from East to West swelled as many of them crossed the pre-defined warning thresholds, and rainfall depths in excess of 200 mm to 600 mm were recorded in over a dozen meteorological stations across the country between 11th and 13th of August. The West Rapti River recorded water level of approximately 9 meters while the adjacent Babai River crossed 10 meters and smaller rivers such as Riu Khola and Kankai rose up to 4.8 meters and 5.5 meters respectively, well above danger levels for consecutive days. Early warning systems established in the aforementioned rivers were critical to saving lives and livelihoods. However the severity of flash floods from intermittent streams that originate from the Churia range caught people unaware and led to massive water logging and devastation across Eastern and Central Nepal that claimed 96 lives and displaced more than 14.060 families. The Department of Hydrology and Meteorology with help from telecom operators sent more than 6 million SMS messages to communities residing along the floodplains. These messages provided them with critical information on when to evacuate their homes and move to safer grounds, yet the shear spatial scale and extend of floods meant that communities struggled to find refuge on higher ground. Whilst the Global Flood Awareness System (GLoFAS) indicated with medium probability that major rivers across Nepal might swell in mid-August and the 3 day rainfall forecasts from the Numerical Weather Prediction (NWP) consistently indicated heavy precipitation in the southern Terai belt, yet no significant early actions were taken in response to this information. Despite the availability of forecast information on streamflow prediction and rainfall, there was limited pre-emptive actions and now it is

Despite the fact that Nepal is one of the first countries globally to introduce multidrug-resistant tuberculosis (MDR-TB) case management, the number of MDR-TB cases is continuing to rise in Nepal. Rapid molecular tests applicable in this setting to identify resistant organisms would be an effective tool in reversing this trend. To develop such tools, information about the frequency and distribution of mutations that are associated with phenotypic drug resistance in Mycobacterium tuberculosis is required. In the present study, we investigated the prevalence of mutations in rpoB and katG genes and the inhA promoter region in 158 M. tuberculosis isolates (109 phenotypically MDR and 49 non-MDR isolates collected in Nepal) by DNA sequencing. Mutations affecting the 81-bp rifampin (RIF) resistance-determining region (RRDR) of rpoB were identified in 106 of 109 (97.3%) RIF-resistant isolates. Codons 531, 526, and 516 were the most commonly affected, at percentages of 58.7, 15.6, and 15.6%, respectively. Of 113 isoniazid (INH)-resistant isolates, 99 (87.6%) had mutations in the katG gene, with Ser315Thr being the most prevalent (81.4%) substitution. Mutations in the inhA promoter region were detected in 14 (12.4%) INH-resistant isolates. The results from this study provide an overview of the current situation of RIF and INH resistance in M. tuberculosis in Nepal and can serve as a basis for developing or improving rapid molecular tests to monitor drug-resistant strains in this country.

Politicians in apron: case study of rebel health services in Nepal.

This article presents the findings of a systematic review on the health consequences of Nepal's armed conflict waged by the Maoists and the development and trajectory of their health workers. Nepal's decade-long violent conflict resulted in more than 13,000 deaths, the destruction of more than 1000 health posts and poor health services delivery. At present, most of the former rebel health workers live in remote/rural areas and some are running health centers. The review found that the Maoists had trained more than 2000 health workers, who can be categorized into 4 levels. However, there is little evidence on their competencies and career motivation. The Maoists demand restructuring of the Nepalese health sector and the integration of their health workforce into the national health system. However, there has been no national discussion in Nepal of what kind of health reform and integration model is appropriate for a sustainable peace and improved service delivery.

Factors associated with the introduction of prelacteal feeds in Nepal: findings from the Nepal Demographic and Health Survey 2011

PubMed Central

2013-01-01

Background A prelacteal feed is any food except mother’s milk provided to a newborn before initiating breastfeeding. Prelacteal feeding is a major barrier to exclusive breastfeeding. It is a prevalent practice in Nepal. Little is known about the factors associated with providing prelacteal feeds to the Nepalese newborn. This study explored the factors associated with providing prelacteal feeds to children under three years in Nepal using the Nepal Demographic and Health Survey (NDHS) 2011. Methods This study utilised the NDHS 2011 child dataset which is a nationally representative study. The rates of providing prelacteal feeds were reported as a proportion. Complex Sample Analysis method was used to account for the cluster design and sample weight of the study. Chi-square tests and multiple logistic regression were used to analyse the factors associated with providing prelacteal feeds. Results A sample of 3948 mothers were included in the study. A total of 841 [26.5% (95% CI: 23.1%–30.3%)] weighted proportion) of mothers reported of providing prelacteal feeds to their newborn infants. Plain water (n = 75), sugar/glucose (n = 35), gripe water (n = 3), sugar/salt solution (n = 3), fruit juice (n = 3), infant formula (n = 96), tea (n = 3) and other milk other than breast milk (n = 556) were some of the types of prelacteal feeds reported. The multiple regression analysis showed that the mothers who had no education, were not working, were from the middle wealth quintile, who had not attended four antenatal care visits, were first time mothers and who were from the Terai/Plain region were more likely to provide prelacteal feeds. Conclusions Given that one in four infants were provided with prelacteal feeds, there is a need to implement breastfeeding promotion programs to increase the practice of exclusive breastfeeding and reduce prelacteal feeding practices.

Context: As physiotherapy (PT) is a young profession in Nepal, there is a dearth of insight into the common practices of physiotherapists in critical care. Aims: To identify the availability of PT services in Intensive Care Units (ICUs) and articulate the common practices by physiotherapists in ICUs of Nepal. Settings and Design: All tertiary care hospitals across Nepal with ICU facility via an exploratory cross-sectional survey. Subjects and Methods: An existing questionnaire was distributed to all the physiotherapists currently working in ICUs of Nepal with 2 years of experience. The survey was sent via E-mail or given in person to 86 physiotherapists. Statistical Analysis Used: Descriptive and inferential statistics according to nature of data. Results: The response rate was 60% (n = 52). In the majority of hospitals (68%), PT service was provided only after a physician consultation, and few hospitals (13%) had established hospital criteria for PT in ICUs. Private hospitals (57.1%) were providing PT service in weekends compared to government hospitals (32.1%) (P = 0.17). The likelihood of routine PT involvement varied significantly with the clinical scenarios (highest 71.2% status cerebrovascular accident, lowest 3.8% myocardial infarction, P < 0.001). The most preferred PT treatment was chest PT (53.8%) and positioning (21.2%) while least preferred was therapeutic exercise (3.8%) irrespective of clinical scenarios. Conclusions: There is a lack of regular PT service during weekends in ICUs of Nepal. Most of the cases are treated by physiotherapists only after physician's referral. The preferred intervention seems to be limited only to chest PT and physiotherapists are not practicing therapeutic exercise and functional mobility training to a great extent. PMID:27076708

The 2009 flu pandemic is a global outbreak of a new strain of H1N1 influenza virus. Pandemic influenza A (H1N1) 2009 has posed a serious public health challenge world-wide. Nepal has started Laboratory diagnosis of Pandemic influenza A/H1N1 from mid June 2009 though active screening of febrile travellers with respiratory symptoms was started from April 27, 2009. Out of 609 collected samples, 302 (49.6%) were Universal Influenza A positive. Among the influenza A positive samples, 172(28.3%) were positive for Pandemic influenza A/H1N1 and 130 (21.3%) were Seasonal influenza A. Most of the pandemic cases (53%) were found among young people with ≤ 20 years. Case Fatality Ratio for Pandemic influenza A/H1N1 in Nepal was 1.74%. Upon Molecular characterization, all the isolated pandemic influenza A/H1N1 2009 virus found in Nepal were antigenically and genetically related to the novel influenza A/CALIFORNIA/07/2009-LIKE (H1N1)v type. The Pandemic 2009 influenza virus found in Nepal were antigenically and genetically related to the novel A/CALIFORNIA/07/2009-LIKE (H1N1)v type.

Nepal has a long tradition of designing good multisectoral nutrition policy. However, success of policy implementation has varied. More evidence on how to successfully carry out multisector nutrition policy is needed. We tracked the influence of Nepal's multisectoral nutrition plan (MSNP) on the process of priority setting and budgeting from 2014 to 2016. This study used a mixed-method longitudinal design to track qualitative and budgetary changes related to MSNP processes nationally as well as in 3 districts. Qualitative changes in each study area were assessed through interviews, observation, news content, and meeting notes. Changes in allocations and expenditures were calculated based on budget documents, work plans, and validation interviews. Improved understanding of the MSNP was documented nationally and in study districts but not in VDCs. Human resources, ownership, bottom-up planning, coordination, advocacy, and sustainable structures all emerged as important factors within the enabling environment. Evidence suggests the MSNP influenced improvements in the last 3 factors. We also found notable increases in activities and financing for nutrition-allocations increased steadily between FY 2013-2014 and FY 2015-2016, and 28% of total nutrition allocations in the final year came from new or expanded MSNP-affiliated activities. Data from 3 districts highlight challenges linking local planning and budgeting to central-level structures. The MSNP appears to have strengthened the nutrition system in Nepal and increased priority and funding for nutrition. Next steps include strengthening linkages to the districts and below. Other countries can learn from the MSNP's success in increasing investment for nutrition. © The Author(s) 2016.

Primarily, health sector connects two segments - medicine and public health, where medicine deals with individual patients and public health with the population health. Budget enables both the disciplines to function effectively. The Interim Constitution of Nepal, 2007 has adapted the inspiration of federalism and declared the provision of basic health care services free of cost as a fundamental right, which needs strengthening under foreseen federalism. An observational retrospective cohort study, aiming at examining the health sector budget allocation and outcome, was done. Authors gathered health budget figures (2001 to 2013) and facts published from authentic sources. Googling was done for further information. The keywords for search used were: fiscal federalism, health care, public health, health budget, health financing, external development partner, bilateral and multilateral partners and healthcare accessibility. The search was limited to English and Nepali-language report, articles and news published. Budget required to meet the population's need is still limited in Nepal. The health sector budget could not achieve even gainful results due to mismatch in policy and policy implementation despite of political commitment. Since Nepal is transforming towards federalism, an increased complexity under federated system is foreseeable, particularly in the face of changed political scenario and its players. It should have clear goals, financing policy and strict implementation plans for budget execution, task performance and achieving results as per planning. Additionally, collection of revenue, risk pooling and purchasing of services should be better integrated between central government and federated states to horn effectiveness and efficiency.

Wild orchids are illegally harvested and traded in Nepal for use in local traditional medicine, horticulture, and international trade. This study aims to: 1) identify the diversity of species of wild orchids in trade in Nepal; 2) study the chain of commercialization from collector to client and/or export; 3) map traditional knowledge and medicinal use of orchids; and 4) integrate the collected data to propose a more sustainable approach to orchid conservation in Nepal. Trade, species diversity, and traditional use of wild-harvested orchids were documented during field surveys of markets and through interviews. Trade volumes and approximate income were estimated based on surveys and current market prices. Orchid material samples were identified to species level using a combination of morphology and DNA barcoding. Orchid trade is a long tradition, and illegal export to China, India and Hong Kong is rife. Estimates show that 9.4 tons of wild orchids were illegally traded from the study sites during 2008/2009. A total of 60 species of wild orchids were reported to be used in traditional medicinal practices to cure at least 38 different ailments, including energizers, aphrodisiacs and treatments of burnt skin, fractured or dislocated bones, headaches, fever and wounds. DNA barcoding successfully identified orchid material to species level that remained sterile after culturing. Collection of wild orchids was found to be widespread in Nepal, but illegal trade is threatening many species in the wild. Establishment of small-scale sustainable orchid breeding enterprises could be a valuable alternative for the production of medicinal orchids for local communities. Critically endangered species should be placed on CITES Appendix I to provide extra protection to those species. DNA barcoding is an effective method for species identification and monitoring of illegal cross-border trade.

The health system in Nepal is characterized by a wide network of health facilities and community workers and volunteers. Nepal's Interim Constitution of 2007 addresses health as a fundamental right, stating that every citizen has the right to basic health services free of cost. But the reality is a far cry. Only 61.8% of the Nepalese households have access to health facilities within 30 min, with significant urban (85.9%) and rural (59%) discrepancy. Addressing barriers to health services needs urgent interventions at the population level. Recently (February 2015), the Government of Nepal formed a Social Health Security Development Committee as a legal framework to start implementing a social health security scheme (SHS) after the National Health Insurance Policy came out in 2013. The program has aimed to increase the access of health services to the poor and the marginalized, and people in hard to reach areas of the country, though challenges remain with financing. Several aspects should be considered in design, learning from earlier community-based health insurance schemes that suffered from low enrollment and retention of members as well as from a pro-rich bias. Mechanisms should be built for monitoring unfair pricing and unaffordable copayments, and an overall benefit package be crafted to include coverage of major health services including non-communicable diseases. Regulations should include such issues as accreditation mechanisms for private providers. Health system strengthening should move along with the roll-out of SHS. Improving the efficiency of hospital, motivating the health workers, and using appropriate technology can improve the quality of health services. Also, as currently a constitution drafting is being finalized, careful planning and deliberation is necessary about what insurance structure may suit the proposed future federal structure in Nepal.

An Assessment of Monsoon Triggered Landslides in Western Nepal

Due to heavy monsoon rain, rugged topography and very young mountains, frequent slope failures and soil erosion are very common in Nepal but in most of cases the natural slopes are disturbed by men to construct a road through it and the situation further aggravated by the Monsoon rain. Summer usually tests the disaster response capacity of Nepal, when the monsoons trigger water induced disasters. This year Nepal's Western regions were most severely affected by floods and landslides. Every year, sadly, it is the same story of mostly poor people living in remote villages succumbing to landslides and flooding and those who survive facing hardships brought on by the disaster. The tail end of the monsoon in October has triggered flood and landslides in Nepal which affected a total of 14 districts in the mid and far-west regions, of which Kailali, Bardiya, Banke, Dadeldhura, Accham and Kanchapur district are most affected. The affected areas are geographically scattered and remote, and are therefore difficult to access. In this year (2009), flood and landslides have claimed 62 lives, affecting more than 152,000 individuals from 27,000 families. More than 4,000 families are displaced and are taking shelter in schools, open space and forest areas with no protection from the external elements. In the above context the prevention and mitigation measures for landslides is a great challenge for Nepal. Nepal has been investing its huge amount of resources to stabilize landslides and roadside slope failures, still then it has become unmanageable during Monsoon time. Considering the above facts, an assessment of landslides which were occurred during the Monsoon (July-October 2009), along Khodpe - Jhota - Chainpur road in far western region of Nepal has been carried out based on the field observation of various landslides. The paper presents the causes and mechanisms of failures of different landslides which are mostly triggered by Monsoon rain. It also suggests some low cost

The high-altitude transverse valleys [>3,000 m above sea level (masl)] of the Himalayan arc from Arunachal Pradesh to Ladahk were among the last habitable places permanently colonized by prehistoric humans due to the challenges of resource scarcity, cold stress, and hypoxia. The modern populations of these valleys, who share cultural and linguistic affinities with peoples found today on the Tibetan plateau, are commonly assumed to be the descendants of the earliest inhabitants of the Himalayan arc. However, this assumption has been challenged by archaeological and osteological evidence suggesting that these valleys may have been originally populated from areas other than the Tibetan plateau, including those at low elevation. To investigate the peopling and early population history of this dynamic high-altitude contact zone, we sequenced the genomes (0.04×–7.25×, mean 2.16×) and mitochondrial genomes (20.8×–1,311.0×, mean 482.1×) of eight individuals dating to three periods with distinct material culture in the Annapurna Conservation Area (ACA) of Nepal, spanning 3,150–1,250 y before present (yBP). We demonstrate that the region is characterized by long-term stability of the population genetic make-up despite marked changes in material culture. The ancient genomes, uniparental haplotypes, and high-altitude adaptive alleles suggest a high-altitude East Asian origin for prehistoric Himalayan populations. PMID:27325755

The Cooperative Monitoring Center (CMC) promotes collaborations among scientists and researchers in several regions as a means of achieving common regional security objectives. To promote cooperation in South Asia on environmental research, an international working group made up of participants from Bangladesh, India, Nepal, Pakistan, and the United States convened in Kathmandu, Nepal, from February 17-23,2002. The workshop was held to further develop the South Asia Transboundary Water Quality Monitoring (SATWQM) project. The project is sponsored in part by the CMC located at Sandia National Laboratories in Albuquerque, New Mexico through funding provided by the US. Department of State, Regionalmore » Environmental Affairs Office, American Embassy, Kathmandu, Nepal, and the National Nuclear Security Administration's (NNSA) Office of Nonproliferation and National Security. This report summarizes the SATWQM project, the workshop objectives, process and results. The long-term interests of the participants are to develop systems for sharing regional environmental information as a means of building confidence and improving relations among South Asian countries. The more immediate interests of the group are focused on activities that foster regional sharing of water quality data in the Ganges and Indus River basins. Issues of concern to the SATWQM network participants include studying the impacts from untreated sewage and industrial effluents, agricultural run-off, salinity increases in fresh waters, the siltation and shifting of river channels, and the environmental degradation of critical habitats such as wetlands, protected forests, and endangered aquatic species conservation areas. The workshop focused on five objectives: (1) a deepened understanding of the partner organizations involved; (2) garnering the support of additional regional and national government and non-government organizations in South Asia involved in river water quality monitoring; (3

90% of Nepal's population is engaged in agriculture; the rural children lack all modern amenities and facilities, and boys are given preference over girls, who do not attend school. In urban populations, girls and boys are treated equally; however, 150,000 children, aged 7 to 16 years, work in carpet factories in unhygienic conditions. 52.71% are illiterate; 47.29% are dropouts. Others work as domestic servants, dishwashers in restaurants, or ragpickers. Many fortunate children do attend schools, which are numerous and filled to capacity. But thousands of Nepalese girls are sold to brothels in Bombay, Calcutta, and other parts of India; upon their return home, they bring human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) with them, as do thousands of male adult migrant workers. A government agency, AIDS Prevention and Control Programme, and about 50 nongovernmental organizations (NGOs) are collaborating to help persons who are infected with HIV or suffering from AIDS. Caritas works with two of the NGOs on a mass education program, prevention, and rehabilitation of HIV-positive women. Although government statistics indicate there are 133 identified cases of HIV in Nepal, the World Health Organization estimates the number of people there who are infected with HIV to be 10,000.

Chemistry labs can become a dangerous environment for students as the lab exercises involve hazardous chemicals, glassware, and equipment. Approximately one hundred thousand students take chemistry laboratory classes annually in Nepal. We conducted a survey on chemical lab safety issues across Nepal. In this paper, we assess the safety policy and equipment, protocols and procedures followed, and waste disposal in chemistry teaching labs. Significant population of the respondents believed that there is no monitoring of the lab safety in their lab (p<0.001). Even though many labs do not allow food and beverages inside lab and have first aid kits, they lack some basic safety equipment. There is no institutional mechanism to dispose lab waste and chemical waste is disposed haphazardly. Majority of the respondents believed that the safety training should be a part of educational training (p = 0.001) and they would benefit from short course and/or workshop on lab safety (p<0.001).

To eliminate visceral leishmaniasis (VL) in India and Nepal, challenges of VL diagnosis, treatment and reporting need to be identified. Recent data indicate that VL is underreported and patients face delays when seeking treatment. Moreover, VL surveillance data might not reach health authorities on time. This study quantifies delays for VL diagnosis and treatment, and analyses the duration of VL reporting from district to central health authorities in India and Nepal. A cross-sectional study conducted in 12 districts of Terai region, Nepal, and 9 districts of Bihar State, India, in 2012. Patients were interviewed in hospitals or at home using a structured questionnaire, health managers were interviewed at their work place using a semi-structured questionnaire and in-depth interviews were conducted with central level health managers. Reporting formats were evaluated. Data was analyzed using two-tailed Mann-Whitney U or Fisher's exact test. 92 VL patients having experienced 103 VL episodes and 49 district health managers were interviewed. Patients waited in Nepal 30 days (CI 18-42) before seeking health care, 3.75 times longer than in Bihar (8d; CI 4-12). Conversely, the lag time from seeking health care to receiving a VL diagnosis was 3.6x longer in Bihar (90d; CI 68-113) compared to Nepal (25d; CI 13-38). The time span between diagnosis and treatment was short in both countries. VL reporting time was in Nepal 19 days for sentinel sites and 76 days for "District Public Health Offices (DPHOs)". In Bihar it was 28 days for "District Malaria Offices". In Nepal, 73% of health managers entered data into computers compared to 16% in Bihar. In both countries reporting was mainly paper based and standardized formats were rarely used. To decrease the delay between onset of symptoms and getting a proper diagnosis and treatment the approaches in the two countries vary: In Nepal health education for seeking early treatment are needed while in Bihar the use of private and non

Gastrointestinal disorders cause morbidity and can lead to mortality, especially in the developing world where sanitation is deficient. A large part of the human population relies on medicinal plants for treating various diseases, including gastrointestinal disorders. The present review summarizes the traditional uses of medicinal plants of Nepal used to treat gastrointestinal disorders, and evaluates their bio-efficacy based on a review of the available phytochemical and pharmacological literature. We searched different electronic databases and libraries for the literature on medicinal plants used in Nepal to treat gastrointestinal disorders. For each species, we also searched the literature for information on conservation status, as well as for phytochemical and pharmacological studies in support of the ethnobotanical information. We used principal component analysis to explore the relation among disorders and plant families, plant life forms, plant parts and preparation modes. We also performed permutation tests to determine if botanical families were used more often than expected considering their availability in the Nepali flora. We documented a total of 947 species belonging to 158 families and 586 genera used to treat gastrointestinal disorders in Nepal. Diarrhea was the disorder treated by the highest number of species (348), followed by stomachache (340) and dysentery (307). Among the reported species, five were endemic to Nepal, whereas 16 orchid species were protected under CITES Appendices II and III. The randomization test showed that species belonging to 14 families were used less often than expected, whereas plants belonging to 25 families were used more often than expected. The PCA scatter plot showed distinct groups of gastrointestinal disorders treated with similar plant life forms, plant parts, and/or preparation modes. We found 763 phytochemical studies on 324 species and 654 pharmacological studies on 269 species. We showed the diversity and

Water sources classified as “improved” may not necessarily provide safe drinking water for householders. We analyzed data from Nepal Multiple Indicator Cluster Survey 2014 to explore the extent of fecal contamination of household drinking water. Fecal contamination was detected in 81.2% (95% confidence interval [CI]: 77.9–84.2) household drinking water from improved sources and 89.6% (95% CI: 80.4–94.7) in water samples from unimproved sources. In adjusted analysis, there was no difference in odds of fecal contamination of household drinking water between improved and unimproved sources. We observed significantly lower odds of fecal contamination of drinking water in households in higher wealth quintiles, where soap and water were available for handwashing and in households employing water treatment. The extent of contamination of drinking water as observed in this study highlights the huge amount of effort required to ensure the provision of safely managed water in Nepal by 2030 as aimed in sustainable development goals.

Despite liberalization of the Nepal abortion law, young women continue to experience barriers to safe abortion services. We hypothesize that marital status may differentially impact such barriers, given the societal context of Nepal. We evaluated differences in reproductive knowledge and attitudes by marital status with a probability-based, cross-sectional survey of young women in Rupandehi district, Nepal. Participants (N = 600) were surveyed in 2012 on demographics, romantic experiences, media habits, reproductive information, and abortion knowledge and attitudes. We used logistic regression to assess differences by marital status, controlling for age. Participants, who comprised never-married (54%) and ever-married women (45%), reported good access to basic reproductive health and abortion information. Social desirability bias might have prevented reporting of premarital romantic and sexual activity given that participants reported more premarital activities for their friends than for themselves. Only 45% knew that abortion was legal, and fewer ever-married women were aware of abortion legality. Never-married women expected more negative responses from having an abortion than ever-married women. Findings highlight the need for providing sexual and reproductive health care information and services to young women regardless of marital status.

Nepal is one of the least developed countries in the world, and education has been a major focus of the government. Half of the population is female, and providing education to women has been one of the biggest challenges to the government. Encouraging science education for girls, with a focus on physics, is even more of a Herculean task. Enrollment of girls in higher education is just over 25%. Data from 2002 to mid-2014 shows that the number of women in physics is increasing gradually, although their numbers are still very low.

Rabies is endemic throughout most of Asia, with the majority of human cases transmitted by domestic dogs (Canis familiaris). Here, we report a case of rabies in a 12-year-old girl in the Lalitpur district of Nepal that might have been prevented by better public awareness and timely post-exposure prophylaxis. Molecular characterization of the virus showed 100% identity over a partial nucleoprotein gene sequence to previous isolates from Nepal belonging to the 'arctic-like' lineage of rabies virus. Sequence analysis of both partial nucleoprotein and glycoprotein genes showed differences in consensus sequence after passage in vitro but not after passage in vivo.

The purpose of this study was to examine the association between perceived family support, either positive or negative, and adherence to antiretroviral medication regimens among HIV-positive individuals in the Kathmandu Valley, Nepal. We measured past 3-month antiretroviral adherence among 233 HIV-positive individuals, in relation to perceived family support, both positive (in terms of emotional and instrumental support) and negative (in the form of negative interactions), using the 10-item Nepali Family Support and Difficulty Scale. Medium and high levels of perceived emotional support from family were associated with reduced risk of antiretroviral nonadherence, compared with low levels of perceived emotional support (adjusted odds ratio [AOR]  = 0.37, 95% confidence interval [CI] [0.16, 0.88], and AOR  = 0.23, 95% CI [0.08, 0.64], respectively). Conversely, higher levels of felt emotional distance (AOR  = 1.46, 95% CI [1.00, 2.14]) and experienced physical harm (AOR  = 2.04, 95% CI [1.07, 3.91]) were associated with increased risk of nonadherence. The results support the recommendation that service providers need to be aware of the significant role of family support in shaping antiretroviral adherence and to consider ways to strengthen positive family support while minimizing negative family interactions to increase adherence rates. © The Author(s) 2015.

Antenatal care has several benefits for expecting mothers and birth outcomes; yet many mothers do not utilise this service in Nepal. Mass media may play an important role in increasing the use of antenatal care and other maternal health services. However, the effect of mass media on increasing health service utilisation has remained an under studied area in Nepal. The aim of this study was to investigate the impact of mass media on the utilisation of antenatal care services in rural Nepal. A community-based cross-sectional study was conducted in Sinurjoda Village Development Committee of Dhanusha District, Nepal. A total of 205 mothers of children aged under 1 year were selected using systematic random sampling. Logistic regression was employed to examine the association between selected antenatal care services and mass media exposure after adjusting for other independent variables. A majority of mothers were exposed to mass media. Radio was accessible to most (60.0%) of the participants followed by television (43.41%). Mothers exposed to mass media were more likely to attending antenatal visits [Odds ratio (OR) 6.28; 95% CI (1.01-38.99)], taking rest and sleep during pregnancy [OR 2.65; 95% CI (1.13-6.26)], and receiving TT immunization [OR 5.12; 95% CI (1.23-21.24)] than their non-exposed counterparts. The study reported a positive influence of mass media on the utilisation of antenatal care services in Nepal. Therefore, further emphasis should be given to increase awareness of women of rural Nepal through mass media to improve utilisation of antenatal care services in Nepal.

Deforestation in Nepal threatens the functioning of complex social-ecological systems, including rural populations that depend on forests for subsistence, as well as Nepal's biodiversity and other ecosystem services. Nepal's forests are particularly important to the nation's poorest inhabitants, as many depend upon them for daily survival. Two-thirds of Nepal's population relies on forests for sustenance, and these pressures are likely to increase in the future. This, coupled with high population densities and growth rates, highlights the importance of studying the relationship between human communities, forest cover trends through time, and forest management institutions. Here, we used surveys to explore how household attitudes associated with conservation-related behaviors in two rural communities—one that has experienced significant forest loss, and the other forest gain—compare with forest cover trends as indicated by satellite-derived forest-loss and -regeneration estimates between 2005 and 2013. Results found a significant difference in attitudes in the two areas, perhaps contributing to and reacting from current forest conditions. In both study sites, participation in community forestry strengthened support for conservation, forest conservation-related attitudes aligned with forest cover trends, and a negative relationship was found between economic status and having supportive forest conservation-related attitudes. In addition, on average, respondents were not satisfied with their district forest officers and did not feel that the current political climate in Nepal supported sustainable forestry. These findings are important as Nepal's Master Plan for the Forestry Sector has expired and the country is in the process of structuring a new Forestry Sector Strategy.

2008-01-01

Internship is an integral part of MBBS training programme and mandatory to all students. Kathmandu University Medical School has adopted a programme of compulsory one year rotating internship including 6 weeks community exposure in out reach clinics for the first batch of students. The purpose of the study is to evaluate interns' feedback concerning learning, education and satisfaction. A questionnaire with 47 items was administered to 30 interns who had finished one year rotating internship in Kathmandu University Medical School. Fourty-two responses were graded according in Likert scale and 5 open ended questions were analyzed for common themes. The mean age of the interns was 24.77+/-0.67 yrs with female: male ratio of 1.5:1. Confidence level of communication of interns with faculties was lesser than with junior doctors and patients. Junior doctors and colleagues contributed more in interns' learning than faculties. Community exposure for 6 weeks was considered lengthy and lacking of clear objectives. However, 53.3% interns agreed that achievement of objectives of community posting was high or very high. Of the interns, 50% perceived certain degree of physical or mental or sexual harassment during internship. Interns raised the issue of not involving them as a part of team during clinical posting. Clinical competencies for most of the skills were high or very high. Interns have learned clinical skills and patient care in one year internship programme but contribution of junior doctors and colleague are more than teachers. Clear objectives are needed before clinical and community postings. Process of providing regular feedback from interns and vice versa should be implemented to improve interns' learning, education and satisfaction.

The involvement of paraveterinarians in animal-health delivery can reduce costs and allow expanded service delivery. Our objectives were to describe use of public paraveterinary services offered by junior technicians (JT) in two regions of Nepal, to identify factors associated with JT service use, and to characterize factors that limit JT service use. We used a survey of livestock owners in the Khumbu and Lower Mustang regions of Nepal's Himalaya to examine JT service use. Of 118 questionnaires completed between May 30, 1997 and July 8, 1997, 81 were analyzed for use of JT services to treat livestock: bovids, equids, and small ruminants. Five factors were associated with owners' use of JT services: living <30 min walk from a JT post (OR=12.2); having a positive opinion about JT services (OR=23.6); animals not having disease events that either impaired mobility or affected production or reproduction (OR=5.6), animals died related to a reported disease event (OR=3.2), and the owners' sex (with women being more likely to report use of JT services than men; OR=5.3).

The rich floral and ethnic composition of eastern Nepal and the widespread utilization of locally available medicinal plants offer remarkable opportunity for ethnomedicinal research. The present paper aims to explore medicinal plant diversity and use in the remote villages of eastern Nepal. It also aims to evaluate ethnopharmacological significance of the documented use reports and identify species of high indigenous priority. The study was undertaken in four villages located in the Sankhuwasabha district in eastern Nepal. Ethnomedicinal information was collected through structured interviews. The homogeneity of informant's knowledge and the relative importance of documented medicinal plants were validated by informant consensus factor and use value, respectively. Species preference for treatment of particular diseases was evaluated through fidelity level. We reported medicinal properties of 48 species belonging to 33 families and 40 genera, for the treatment of 37 human ailments. The uses of 10 medicinal plants were previously undocumented. The informant consensus factor (F IC ) ranged between 0.38 and 1 with about 50% of values greater than 0.80 and over 75% of values greater than 0.70, indicating moderate to high consensus among the informants on the use of medicinal plants in the region. Swertia chirayita was the most preferred species with significantly high use values, followed by Paris polyphylla and Neopicrorhiza scrophulariiflora. The remote villages in eastern Nepal possess rich floral and cultural diversity with strong consensus among informants on utilization of plants for local healthcare. The direct pharmacological evidence for medicinal properties of most species indicates high reliability of documented information. Careful and systematic screening of compounds isolated from these plants could possibly provide good opportunity for the discovery of novel medicines to treat life-threatening human diseases. We recommend prioritization of medicinal

Accessibility and affordability of evidence-based medicines are issues of global concern. For low-income countries like Nepal, it is crucial to have easy and reliable access to affordable, good-quality, evidence-based medicines, especially in the aftermath of natural or manmade disasters. Availability of affordable and evidence-based high quality medicines depends on the medicine procurement procedure, which makes it an important aspect of healthcare delivery. In this study, we aimed to investigate medicine procurement practices in hospital pharmacies of Nepal within the framework of International Pharmaceutical Federation [FIP] hospital pharmacy guidelines "the Basel Statements". We conducted semi-structured interviews with hospital pharmacists or procurement officers in hospital pharmacies of four major regions in Nepal to explore procurement practices. Data were collected until saturation of themes, analysed using the framework approach, and organised around the statements within the procurement theme of the Basel Statements. Interviews conducted with 53 participants revealed that the procurement guidelines of the Basel Statements were adopted to a certain extent in hospital pharmacies of Nepal. It was found that the majority of hospital pharmacies in Nepal reported using an expensive direct-procurement model for purchasing medicines. Most had no formulary and procured medicines solely based on doctors' prescriptions, which were heavily influenced by pharmaceutical companies' marketing strategies. Whilst most procured only registered medicines, a minority reported purchasing unregistered medicines through unauthorised supply-chains. And although the majority of hospital pharmacies had some contingency plans for managing medicine shortages, a few had none. Procurement guidelines of the Basel Statements were thus found to be partially adopted; however, there is room for improvement in current procurement practices in hospital pharmacies of Nepal.

Background Abortion was legalized in Nepal in 2002, following advocacy efforts highlighting high maternal mortality from unsafe abortion. We sought to assess whether legalization led to reductions in the most serious maternal health consequences of unsafe abortion. Methods We conducted retrospective medical chart review of all gynecological cases presenting at four large public referral hospitals in Nepal. For the years 2001–2010, all cases of spontaneous and induced abortion complications were identified, abstracted, and coded to classify cases of serious infection, injury, and systemic complications. We used segmented Poisson and ordinary logistic regression to test for trend and risks of serious complications for three time periods: before implementation (2001–2003), early implementation (2004–2006), and later implementation (2007–2010). Results 23,493 cases of abortion complications were identified. A significant downward trend in the proportion of serious infection, injury, and systemic complications was observed for the later implementation period, along with a decline in the risk of serious complications (OR 0.7, 95% CI 0.64, 0.85). Reductions in sepsis occurred sooner, during early implementation (OR 0.6, 95% CI 0.47, 0.75). Conclusion Over the study period, health care use and the population of reproductive aged women increased. Total fertility also declined by nearly half, despite relatively low contraceptive prevalence. Greater numbers of women likely obtained abortions and sought hospital care for complications following legalization, yet we observed a significant decline in the rate of serious abortion morbidity. The liberalization of abortion policy in Nepal has benefited women’s health, and likely contributes to falling maternal mortality in the country. The steepest decline was observed after expansion of the safe abortion program to include midlevel providers, second trimester training, and medication abortion, highlighting the importance

The purpose of this paper is to describe and discuss policy analysis in Nepal and review the wide range of choices feasible in decentralisation decision making. In this paper an iterative qualitative method was developed and used in the research, which consisted of focus group interviews, key informant interviews, document analysis, including descriptive statistics, and analysis of the policy context. Participants in the research reflected the urban/rural mix of districts and the geography of Nepal. Analysis combined transcribed interviews with findings from document searches and analysis of the policy context. Coding was pre-determined during the training workshop and further codes were generated during and after the fieldwork. The paper finds that Nepal is in the process of decentralising public services from the central level to the local level, particularly to local bodies: District Development Committees (DDCs), Village Development Committees (VDCs) and Municipalities. Key contextual factors referred to are the overall structure of decentralisation, the social context of poverty and the political instability leading to a fluid political situation characterised by political tension, armed conflict, controversies and agreements while carrying out the research. The key issues identified and discussed in the paper are the policy process leading to decentralisation, the organisational structure and tension in the proposed system, the systems of resource generation, allocation, planning and management and lastly the forms of accountability, participation, public-private relations and collaborative strategies. The paper discusses the challenges faced in conducting such a policy analysis, the broad ranging and unremitting nature of the decentralisation process, and the contextual setting of the process of change.

As Nepal mourns the 1-year commemoration of the April 2015 earthquake and its aftershocks that killed more than 8500 people and left thousands injured and displaced, other more hidden repercussions of the resultant chaotic environment need attention: the increased risk of human trafficking. Considering that natural disasters provide a milieu for this illicit trade, there is a need for a robust response from stakeholders such as donors, civil society organizations, and government organizations against human trafficking following disasters such as the Nepal earthquake. Responsibility to prevent and fight trafficking should be explicitly included in the mandate of relief and rehabilitation mechanisms set up at the national level to coordinate the disaster relief response, serving to support populations in both rural and urban areas.

Morphometric data on the runoff and sapping valleys on the slopes of Hawaii and Molokai in Hawaii are analyzed. The analysis reveals a clear distinction between the runoff valleys and sapping valleys. The Hawaiian sapping valleys are characterized by: (1) steep valley walls and flat floors, (2) amphitheater heads, (3) low drainage density, (4) paucity of downstream tributaries, (5) low frequency of up-dip tributaries, and (6) structural and stratigraphic control on valley patterns. The characteristics of the Hawaiian sapping valleys are compared to Martian valleys and experimental systems, and good correlation between the data is detected. Flume experiments were also conducted to study the evolution of sapping valleys in response to variable structure and stratigraphy.

Nepal lacks sufficient data on injury and violence. Studies have been done in different regions but there is not a nationwide study on this topic. So, we have designed this systematic review to get a cumulative picture of injury and violence status in Nepal. We searched Medline database, Google scholar database and also all the national medical journals for relevant studies on injuries and violence. Our eligibility criteria included studies done in Nepal, evaluating the incidence of different forms of injuries, and their causes and effects. We excluded case reports, editorials and reviews. All together, we had 23 studies. We made cumulative analysis wherever possible. All the studies were descriptive. In overall, the incidence of injuries was twice as common in male as in female with the ratio of 2.1:1. The economically active population between 20-50 years of age was mostly involved in injuries. Road traffic injuries were the most common form of injuries, most of which (42.5%) involved motorcycles. Pedestrians (48.6%) were the most vulnerable group of population. Falls (48.9%) were the most common cause of neuro traumatic accidents. Our systematic review suggests that injuries and violence pose a big problem; road traffic accidents make the most part of it.

Pregnancy-related morbidity and mortality are much more prevalent among adolescents than adults, particularly in low-income settings. Little is known about risk factors for pregnancy among adolescents in Nepal, but setting-specific evidence is needed to inform interventions. This study aimed to describe the prevalence, and identify factors associated with pregnancy among adolescents in Nepal between 2001 and 2011. Secondary analyses of Nepal Demographic Health Surveys (NDHS) data from 2001, 2006, and 2011 were completed. The outcome was any pregnancy or birth among married adolescents; prevalence was calculated for each survey year. Although the rate of marriage among adolescent women in Nepal decreased significantly from 2001 to 2011, prevalence of pregnancy and birth among married adolescent women in Nepal remains high (average 56%) in Nepal, and increased significantly between 2001 and 2011. Regression analyses of this outcome indicate higher risk was associated with living in the least resourced region, early sexual debut, and older husband. Despite national efforts to reduce pregnancies among married adolescent women in Nepal, prevalence remains high. Integrated, cross-sectoral prevention efforts are required. Poverty reduction and infrastructure improvements may lead to lower rates of adolescent pregnancy. PMID:29385771

Ugly bugs in healthy guts! Carriage of multidrug-resistant and ESBL-producing commensal Enterobacteriaceae in the intestine of healthy Nepalese adults.

Fecal carriage of multidrug-resistant and extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae is one of the important risk factors for infection with antibiotic-resistant bacteria. In this report, we examined the prevalence of multidrug-resistant and ESBL-producing common enterobacterial strains colonizing the intestinal tract of apparently healthy adults in Kathmandu, Nepal. During a 6-month period (February-July 2016), a total of 510 stool specimens were obtained from apparently healthy students of Manmohan Memorial Institute of Health Sciences, Kathmandu, Nepal. Stool specimens were cultured, and the most common enterobacterial isolates ( Escherichia coli and Klebsiella species) were subjected to antimicrobial susceptibility tests according to the standard microbiologic guidelines. Multidrug-resistant isolates were selected for ESBL confirmation by combined disk test and E-test methods. Molecular characterization of plasmid-borne ESBL genes was performed by using specific primers of cefotaximase Munich (CTX-M), sulfhydryl variant (SHV), and temoniera (TEM) by polymerase chain reaction. Among 510 bacterial strains, E. coli (432, 84.71%) was the predominant organism followed by Klebsiella oxytoca (48, 9.41%) and K. pneumoniae (30, 5.88%). ESBLs were isolated in 9.8% of the total isolates including K. oxytoca (29.17%), E. coli (7.87%), and K. pneumoniae (6.67%). Among ESBLs, bla -TEM was the predominant type (92%) followed by bla -CTX-M (60%) and bla -SHV (4%). Multidrug-resistant and ESBL-producing enterobacterial commensal strains among healthy individuals are of serious concern. Persistent carriage of ESBL organisms in healthy individuals suggests the possibility of sustained ESBL carriage among the diseased and hospitalized patients. We recommend similar types of epidemiologic surveys in larger communities and in hospital settings to ascertain the extent of ESBL resistance.

Assessing the Groundwater Concentrations and Geographical Distribution of Arsenic in Nepal

Arsenic 33As, one of the major groundwater contaminants, occurs in both natural and anthropogenic forms. Arsenic inhibits cellular respiration and the production of ATP in human body. Prolonged intake of non-lethal quantities of arsenic can cause cancer and diseases in vital organs such as the heart, liver, skin, and kidney. Each year, millions of people in the rural areas of Bangladesh, India, and other developing countries in South Asia are exposed to arsenic-poisoned groundwater. According to the World Health Organization, arsenic levels in drinking water should not exceed 10 parts per billion; however, the levels of arsenic found in groundwater in the heavily contaminated regions are often more than ten times of the recommended limit. Nepal is one of these regions. In most of the rural areas in Nepal, there is no infrastructure to produce clean filtered water, and wells thus became the major source. However, most of these wells were dug without testing for groundwater safety, because the test commands resources that the rural communities do not have access to. This is also limited data published on Nepal's groundwater contaminant levels. The scarcity of information prohibits the international community from recognizing the severity of arsenic poisoning in Nepal and coming up with the most efficient measures to help. With this project, we will present a method to determine groundwater safety by analyzing geologic data and using remote sensing. The original source of arsenic is the arsenic-bearing minerals in the sediments. Some geological formations have higher arsenic levels than others due to their depositional environments. Therefore, by using existing geologic data from Nepal and countries with similar types of arsenic contamination, we hope to determine correlations between areas where there are reports of high concentrations of arsenic in groundwater to the environmental factors that may cause a particular concentration of arsenic. Furthermore, with deeper

Water sources classified as "improved" may not necessarily provide safe drinking water for householders. We analyzed data from Nepal Multiple Indicator Cluster Survey 2014 to explore the extent of fecal contamination of household drinking water. Fecal contamination was detected in 81.2% (95% confidence interval [CI]: 77.9-84.2) household drinking water from improved sources and 89.6% (95% CI: 80.4-94.7) in water samples from unimproved sources. In adjusted analysis, there was no difference in odds of fecal contamination of household drinking water between improved and unimproved sources. We observed significantly lower odds of fecal contamination of drinking water in households in higher wealth quintiles, where soap and water were available for handwashing and in households employing water treatment. The extent of contamination of drinking water as observed in this study highlights the huge amount of effort required to ensure the provision of safely managed water in Nepal by 2030 as aimed in sustainable development goals. © The American Society of Tropical Medicine and Hygiene.

A powerful 7.8 magnitude earthquake struck Nepal at 06:11 UTC on 25 April 2015. Several subsequent aftershocks were deadliest earthquake in recent history of Nepal. In total about 9000 people died and 22,300 people were injured, and lives of eight million people, almost one-third of the population of Nepal was effected. The event lead to massive campaigned to gather data and information on damage and loss using remote sensing, field inspection, and community survey. Information on distribution of relief materials is other important domain of information necessary for equitable relief distribution. Pre and post-earthquake high resolution satellite images helped in damage area assessment and mapping. Many national and international agencies became active to generate and fill the information vacuum. The challenges included data access bottleneck due to lack of good IT infrastructure; inconsistent products due to absence of standard mapping guidelines; dissemination challenges due to absence of Standard Operating Protocols and single information gateway. These challenges were negating opportunities offered by improved earth observation data availability, increasing engagement of volunteers for emergency mapping, and centralized emergency coordination practice. This paper highlights critical practical challenges encountered during emergency mapping and information management during the earthquake in Nepal. There is greater need to address such challenges to effectively use technological leverages that recent advancement in space science, IT and mapping domain provides.

Due to recent emergence, dengue is becoming one of the major public health problems in Nepal. The numbers of reported dengue cases in general and the area with reported dengue cases are both continuously increasing in recent years. However, spatiotemporal patterns and clusters of dengue have not been investigated yet. This study aims to fill this gap by analyzing spatiotemporal patterns based on monthly surveillance data aggregated at district. Dengue cases from 2010 to 2014 at district level were collected from the Nepal government's health and mapping agencies respectively. GeoDa software was used to map crude incidence, excess hazard and spatially smoothed incidence. Cluster analysis was performed in SaTScan software to explore spatiotemporal clusters of dengue during the above-mentioned time period. Spatiotemporal distribution of dengue fever in Nepal from 2010 to 2014 was mapped at district level in terms of crude incidence, excess risk and spatially smoothed incidence. Results show that the distribution of dengue fever was not random but clustered in space and time. Chitwan district was identified as the most likely cluster and Jhapa district was the first secondary cluster in both spatial and spatiotemporal scan. July to September of 2010 was identified as a significant temporal cluster. This study assessed and mapped for the first time the spatiotemporal pattern of dengue fever in Nepal. Two districts namely Chitwan and Jhapa were found highly affected by dengue fever. The current study also demonstrated the importance of geospatial approach in epidemiological research. The initial result on dengue patterns and risk of this study may assist institutions and policy makers to develop better preventive strategies.

Cultural heritage structural documentation is of great importance in terms of historical preservation, tourism, educational and spiritual values. Cultural heritage across the world, and in Nepal in particular, is at risk from various natural hazards (e.g. earthquakes, flooding, rainfall etc), poor maintenance and preservation, and even human destruction. This paper evaluates the feasibility of low-cost photogrammetric modelling cultural heritage sites, and explores the practicality of using photogrammetry in Nepal. The full pipeline of 3D modelling for heritage documentation and conservation, including visualisation, reconstruction, and structure analysis, is proposed. In addition, crowdsourcing is discussed as a method of data collection of growing prominence.

2010-06-01

The future toll of the obesity epidemic will likely hit hardest in low- and middle-income countries. Ongoing urbanization promotes risk factors including sedentary lifestyle and fat- and sugar-laden diets. Low-income countries like Nepal experience a double disease burden: infectious diseases as well as rising incidence of noncommunicable diseases (e.g., cardiovascular disease and diabetes mellitus) frequently characterized by obesity. Nepal currently directs efforts towards curing disease but pays little attention to preventive actions. This article highlights obesity prevalence in Nepal, delineates the challenges identified by our pilot study (including low health literacy rates), and suggests strategies to overcome this trend.

Factors associated with the utilisation of postnatal care services among the mothers of Nepal: analysis of Nepal Demographic and Health Survey 2011

PubMed Central

2014-01-01

Background Postnatal care is essential to save the life of the mother and newborn. Knowledge on the determinants of postnatal care assists the policy makers to design, justify and implement appropriate interventions. The current study aimed to analyse the factors associated with utilisation of postnatal care services by mothers in Nepal based on the data from Nepal Demographic and Health Survey (NDHS) 2011. Methods This study utilised the data from NDHS 2011. The association between utilisation of at least one postnatal care visit (within 6 weeks of delivery) and immediate postnatal care (within 24 hours of delivery) with selected factors was examined by using Chi-square test (χ2), followed by multiple logistic regression. Result Of the 4079 mothers, 43.2% reported attending postnatal care within the first six weeks of birth, while 40.9% reported attending immediate postnatal care. Mothers who were from urban areas, from rich families, who were educated, whose partners were educated, who delivered in a health facility, who had attended a four or more antenatal visits, and whose delivery was attended by a skilled attendant were more likely to report attending at least one postnatal care visit. On the other hand, mothers who reported agricultural occupation, and whose partners performed agricultural occupation were less likely to have attended at least one postnatal care visit. Similarly, mothers who were from the urban areas, from rich families, who were educated, whose partners were educated, who had attended four or more antenatal visits, who delivered in a health facility and had delivered in the presence of a skilled birth attendant were more likely to report attending immediate postnatal care. Mothers who reported agricultural occupation, and whose partners performed agricultural occupation were less likely to attend immediate postnatal care. Conclusion The majority of postnatal mothers in Nepal did not seek postnatal care. Increasing utilisation of the

Women and citizenship post‐trafficking: the case of Nepal

Abstract This article analyses the relationship between gender, sexuality and citizenship embedded in models of citizenship in the Global South, specifically in South Asia, and the meanings associated with having – or not having – citizenship. It does this through an examination of women's access to citizenship in Nepal in the context of the construction of the emergent nation state in the ‘new’ Nepal ‘post‐conflict’. Our analysis explores gendered and sexualized constructions of citizenship in this context through a specific focus on women who have experienced trafficking, and are beginning to organize around rights to sustainable livelihoods and actively lobby for changes in citizenship rules which discriminate against women. Building from this, in the final section we consider important implications of this analysis of post‐trafficking experiences for debates about gender, sexuality and citizenship more broadly.

Wadhawan, M.; Hazarika, D.; Paul, A.; Kumar, N.

2016-12-01

The ongoing continental collision between India and Eurasia gave rise to the formation of the great Himalayan fold-thrust belt. Satluj valley is found to be well exposed from foreland to Higher Himalayan Crystalline series along the Satluj River. Receiver function method has been utilized to image crustal features using Common Conversion Point (CCP) stacking beneath Satluj valley recorded by a seismological array of 18 broadband seismometers. The seismological stations cover the geotectonic units starting from the Himalayan Frontal Thrust (HFT) in the south to the Tethyan Himalaya (TH) to the north. The study inferred gentle northward dipping nature of the Main Himalayan Thrust (MHT) between Sub Himalaya (SH) and Higher Himalaya (HH) in the study area rather than flat-ramp-flat geometry as reported in Nepal Himalaya and Garhwal Himalaya. The depth of the MHT obtained from CCP image and inversion of receiver functions shows that it varies from 16 km in the SH to 27 km near the STD which further increases up to 38 km beneath the TH. The absence of both large and moderate magnitude earthquakes in the Himalayan Seismic Belt (HSB) straddling northern Lesser Himalaya and southern Higher Himalaya in Satluj valley is correlated with absence of ramp structure in this part of HSB. The CCP image has mapped the Moho discontinuity at 44 km depth near the HFT which has increased to 62 km beneath the TH. An extremely low shear wave velocity ranging between 0.8 and 1.8 km s-1 is estimated at stations near the HFT, in the upper most 3-4 km of the crust which indicates the effect of sedimentary column of Indo-Gangetic plains. An intra crustal low velocity layer (IC-LVL) is observed beneath the study profile and inferred as partial melt and/or aqueous fluid at mid-crustal depth beneath the TH. The H-K stacking is applied and average Poisson's ratio is observed to be higher in the TH as compared to the stations to the south of STD.

Rabies is a zoonotic disease that is endemic in many parts of the developing world, especially in Africa and Asia. However its epidemiology remains largely unappreciated in much of these regions, such as in Nepal, where limited information is available about the spatiotemporal dynamics of the main etiological agent, the rabies virus (RABV). In this study, we describe for the first time the phylogenetic diversity and evolution of RABV circulating in Nepal, as well as their geographical relationships within the broader region. A total of 24 new isolates obtained from Nepal and collected from 2003 to 2011 were full-length sequenced for both the nucleoprotein and the glycoprotein genes, and analysed using neighbour-joining and maximum-likelihood phylogenetic methods with representative viruses from all over the world, including new related RABV strains from neighbouring or more distant countries (Afghanistan, Greenland, Iran, Russia and USA). Despite Nepal's limited land surface and its particular geographical position within the Indian subcontinent, our study revealed the presence of a surprising wide genetic diversity of RABV, with the co-existence of three different phylogenetic groups: an Indian subcontinent clade and two different Arctic-like sub-clades within the Arctic-related clade. This observation suggests at least two independent episodes of rabies introduction from neighbouring countries. In addition, specific phylogenetic and temporal evolution analysis of viruses within the Arctic-related clade has identified a new recently emerged RABV lineage we named as the Arctic-like 3 (AL-3) sub-clade that is already widely spread in Nepal.
