Introduction Menstrual hygiene management can be challenging in low-income settings and among school-aged girls due to traditional beliefs, lack of knowledge and information on best hygienic practices, and limited access to appropriate and affordable menstrual hygiene products. An alternative method for menstrual hygiene management, instead of sanitary pads or tampons, is the vaginal menstrual cup. As evidence on the use of menstrual cups is relatively limited, this study aimed to explore the acceptability and feasibility of using vaginal menstrual cups among school-aged girls in Thokarpa, Sindupalchowk, Nepal. Methods This is an exploratory study based on four focus group discussions with a purposive sample of 28 schoolgirls between 13 and 19 years of age who were provided with vaginal menstrual cups in Thokarpa, Sindupalchowk, Nepal. The data were collected between February and March 2019, i.e. approximately three months after the distribution of the menstrual cup. Participants were included in the study if they had started their menstruation and never given birth. Conventional content analysis was applied. Results Most participants perceived the menstrual cup positively. Not missing a single class in school due to problems related to menstrual hygiene management was described as a major benefit. The participants found using the menstrual cup easy and convenient, and described economic and environmental advantages of using it. Cleaning the menstrual cup did not cause any problems, according to the participants. Discomforts mentioned by the participants were: pain when inserting the menstrual cup, feeling the menstrual cup sticking out of the vagina, feeling a constant urge to urinate and leakage. Concerns were related to the size, shape and texture of the menstrual cup, and that it may “get stuck” in the vagina, while relatives were said to be concerned about the use of the menstrual cup leading to reduced fertility or losing virginity. Conclusion The use of vaginal menstrual cups for menstrual hygiene management among schoolgirls in Thokarpa, Sindupalchowk, Nepal, appears feasible and acceptable, as it involves practical, economic and environmental advantages. However, the scale-up of menstrual cups will require resolving described concerns and discomforts and fostering peer and family support.

Campylobacter jejuni is one of the most common causes of foodborne human gastroenteritis in the developed world. This bacterium colonizes in the ceca of chickens, spreads throughout the poultry production chain, and contaminates poultry products. Despite numerous on farm intervention strategies and developments in post-harvest antimicrobial treatments, C. jejuni is frequently detected on broiler meat products. This indicates that C. jejuni is evolving over time to overcome the stresses/interventions that are present throughout poultry production and processing. The development of aerotolerance has been reported to be a major survival strategy used by C. jejuni in high oxygen environments. Recent studies have indicated that C. jejuni can enter a viable but non-culturable (VBNC) state or develop biofilm in response to environmental stressors such as refrigeration and freezing stress and aerobic stress. This review provides an overview of different stressors that C. jejuni are exposed to throughout the poultry production chain and the genotypic and phenotypic survival mechanisms, with special attention to aerotolerance, biofilm formation, and development of the VBNC state.

Pigs play a key role in inter-species transmission of influenza virus, because they have receptors to both avian and human influenza viral strains. A study was conducted in three different districts namely Bhaktapur, Kavre and Banke with face to face type of questionnaire survey and serum sample collection. Indirect Enzyme Linked Immunoassay was utilized for the collected 231 samples for serologic evidence of influenza A. Of the total 231 samples tested, 11 were positive for Influenza virus A with an overall sero-prevalence of (4.76%; Cl95%: 2.68-8.324) Kavre district had highest (5.88%; Cl95%: 2.539-13.04) sero-prevalence, followed by Bhaktapur (5.13%; Cl95%: 2.012-12.46) and Banke (2.94%; Cl95%; 0.8104-10.1) with no significant difference (p=0.685). Rearing swine along with poultry was the most significant risk factor (p=0.03); all positive cases were from the farms that adopted integrated farming system with little to no bio-security measures, especially poultry and swine. Present finding depicts that Influenza A is prevalent in pig farms of Kavre, Banke and Bhaktapur. Further research is needed to sub-type the influenza virus and also determine the effect of commercial poultry and migratory birds on the outbreak of influenza A in swine.  Int. J. Appl. Sci.

This study characterized biofilm formation of various Salmonella strains on common processing plant surface materials (stainless steel, concrete, rubber, polyethylene) under static and fluidic shear stress conditions. Surface-coupons were immersed in well-plates containing 1 mL of Salmonella (6 log CFU/mL) and incubated aerobically for 48 h at 37 °C in static or shear stress conditions. Biofilm density was determined using crystal violet assay, and biofilm cells were enumerated by plating on tryptic soy agar plates. Biofilms were visualized using scanning electron microscopy. Data were analyzed by SAS 9.4 at a significance level of 0.05. A surface–incubation condition interaction was observed for biofilm density (p < 0.001). On stainless steel, the OD600 was higher under shear stress than static incubation; whereas, on polyethylene, the OD600 was higher under static condition. Enumeration revealed surface–incubation condition (p = 0.024) and surface–strain (p < 0.001) interactions. Among all surface–incubation condition combinations, the biofilm cells were highest on polyethylene under fluidic shear stress (6.4 log/coupon; p < 0.001). Biofilms of S. Kentucky on polyethylene had the highest number of cells (7.80 log/coupon) compared to all other strain–surface combinations (p < 0.001). Electron microscopy revealed morphological and extracellular matrix differences between surfaces. Results indicate that Salmonella biofilm formation is influenced by serotype, surface, and fluidic shear stress.

Background: Abortion is legal up to 12 weeks’ gestation period in Nepal. Due to a lack of proper abortion services and socio cultural stigma, every year many women died due to abortion. The aim of this study was to asses the knowledge, attitude and practice of abortion in the residents of slum area of Kathmandu district. Methods: The cross-sectional study was conducted in slum area of Kathmandu district from 20th December, 2020 to 15th January, 2021. The sample size was 255 and convenient sampling technique was used to select the participant aged above 15years. The collected data were enter in MS excel and analysis was performed using SPSS version 22. Results: The prevalence of abortion was 25.27%.The level of knowledge was found significant with education status. Age, marital status, ethnicity were found significant with attitude of the respondents. Ten percentages of the female respondents had done unsafe abortion. The complications after abortion were the bleeding (54.3%), trauma (15.20%), loss of consciousness (13.0%) and abdominal pain (2.20%). Conclusions: The level of knowledge of participants of the present study found to be satisfactory but attitude was less satisfactory with compared to the knowledge about the abortion.
