A qualitative study to understand drivers of psychoactive substance use among Nepalese youth

Background Psychoactive substance use among youth is an emerging public health issue in Nepal. This exploratory study aimed to better understand the drivers of psychoactive substance use among Nepalese youth in Rupandehi district of Nepal. Materials and methods This study used a qualitative approach for data collection. Both in-depth interviews (IDI, seven participants) and focus group discussions (FGD, 13 participants) were conducted among study participants who self-reported as psychoactive substance users or had history of psychoactive substance use. Participants for IDI were aged between 11 and 24 years and between 18 and 35 years old for FGDs. Semi-structured interview guides were prepared separately for IDIs and FDGs. Interviews were conducted in Nepali language and were audio recorded, which were there transcribed and translated into English for coding and analyses. In addition, interviews notes were taken by two research assistants. An inductive thematic analysis was used to analyze the data. Results This study identified a range of drivers of psychoactive substances use among Nepalese youths. Themes included (i) socio-cultural factors, (ii) individual factors, (iii) academic environment, (iv) physical environment and the (v) influence of media. The socio-cultural factors were categorized into sub-themes of family relationships, ethnic identity and psychoactive substance use and lack of social acceptance. Individual factors included peer pressure, stress relief and coping with financial challenges. Accessibility and availability of psychoactive substances in the surrounding environment and lack of monitoring and reinforcement of rules/ law and regulations were other drivers to psychoactive substance use among this Nepalese youth cohort. Conclusion Our study identified several important drivers of psychoactive substance use among youth in the Rupandehi district of Nepal. Future works are anticipated to further explore youth initiation and use of psychoactive substances and support the design of interventions that address these risk factors to reduce and prevent subsequent harms

Using simulated rainfall to evaluate cover crops and winter manure application to limit nutrient loss in runoff

Abstract Cover crops can be effective in minimizing nutrient losses from agricultural fields. The objective of this study was to determine the impact of cover crop (rye, Secale cereale L.) and winter manure application on nutrient loss in simulated rainfall runoff. A split block design study with manure (as vertical block) and cover crops (as horizontal block) was established in 2009. Two rain simulations (the first defined as “dry” and the second “wet”) using sixteen 4 m2 steel frames were conducted in May 2010. The runoff volume collected from each plot was analyzed for nitrate–nitrogen (NO3–N), total suspended solids, total Kjeldahl nitrogen, total phosphorus, and total dissolved phosphorus. In the dry run, the concentration and load of NO3–N were significantly lower (p = 0.05) in runoff with the cover crop than in no‐cover crop treatment. Overall, cover crops reduced nutrient loss in concentration by 6%–48% in the dry and 8%–40% in the wet run than with no‐cover crops. The concentration and load of NO3–N were significantly higher under manure treatments in both “dry” and “wet” runoff runs compared to no‐manure application. Manure application increased nutrient loss in concentration by 6%–58% in the dry and 10%–69% in the wet run than with no‐manure application. This study helps us to understand the complexity of winter manure application with cover crops and potential risks of nutrient loss to surface runoff during spring in the Northern Great plains of the Dakotas

Village-integrated eye workers for prevention of corneal ulcers in Nepal (VIEW study): a cluster-randomised controlled trial

BackgroundCorneal ulcers are a common cause of blindness in low-income and middle-income countries, usually resulting from traumatic corneal abrasions during agricultural work. Antimicrobial prophylaxis of corneal abrasions can help prevent corneal ulcers, but delays in the initiation of therapy are frequent. We aimed to assess whether a community-based programme for corneal ulcer prevention would reduce the incidence of corneal ulceration.MethodsA cluster-randomised trial was performed in village development committees (VDCs) in Nepal. VDCs in the catchment area of Bharatpur Eye Hospital, Nepal with less than 15 000 people were eligible for inclusion. We randomly assigned (1:1) VDCs to either an intervention group or a control group. In the intervention VDCs, existing female community health volunteers (FCHVs) were trained to diagnose corneal abrasions and provide a 3-day course of ophthalmic antimicrobials to their patients. In the control VDCs, FCHVs did not provide this intervention. Participants were not masked given the nature of the intervention. Both groups were followed up for 3 years for photographic evidence of corneal ulceration. The primary outcome was the incidence of corneal ulceration, determined by masked assessment of corneal photographs. The analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, NCT01969786.FindingsWe assessed 112 VDCs, of which 24 were enrolled. The study was performed between Feb 4, 2014, and Oct 20, 2017. 12 VDCs were randomly assigned to the intervention group and 12 to the control group. 252 539 individuals were included in the study (130 579 in the intervention group and 121 960 in the control group). FCHVs diagnosed and provided antimicrobials for 4777 corneal abrasions. The census identified 289 corneal ulcers among 246 893 person-years in the intervention group (incidence 1·21 cases [95% CI 0·85-1·74] per 1000 person-years) and 262 corneal ulcers among 239 170 person-years in the control group (incidence 1·18 cases [0·82-1·70] per 1000 person-years; incidence rate ratio 1·03 [95% CI 0·63-1·67]; p=0·93). Medication allergy was self-reported in 0·2% of participants.InterpretationWe did not detect a reduction in the incidence of corneal ulceration during the first 3 years of a community-based corneal ulcer prevention programme. Further study might be warranted in more rural areas where basic eye care facilities are not available.FundingNational Eye Institute
