- Abstract
Objective: Given the population-level variation in stature, a universal cut-off for waist circumference (WC) may not be appropriate for some populations. We compared the performance of WC and waist-to-height ratio (WHtR) to detect the clustering of cardiovascular disease (CVD) risk factors in rural Vietnam., Methods: We obtained data from a baseline survey of the Khanh Hoa Cardiovascular Study comprising 2942 middle-aged residents (40-60 years). We used areas under the receiver operating characteristics curve (AUROC), net reclassification index (NRI), and integrated discrimination improvement (IDI) to compare the performance of WC and WHtR in predicting CVD risk clustering (≥2 of the following risk factors: hypertension, diabetes, dyslipidemia, and elevated C-reactive protein)., Results: The optimal cut-off values for WC were 81.8 and 80.7 cm for men and women, respectively. Regarding the clustering of CVD risk factors, the AUROC (95% CI) of WC and WHtR were 0.707 (0.676 to 0.739) and 0.719 (0.689 to 0.749) in men, and 0.682 (0.654 to 0.709) and 0.690 (0.663 to 0.717) in women, respectively. Compared with WC, WHtR had a better NRI (0.229; 0.102-0.344) and IDI (0.012; 0.004-0.020) in men and a better NRI (0.154; 0.050-0.257) in women., Conclusions: The optimal WC cut-off for Vietnamese men was approximately 10 cm below the recommended Asian cut-off. WHtR might perform slightly better in predicting the clustering of CVD risk factors among the rural population in Vietnam., (© 2024 Wiley Periodicals LLC.)

- Abstract
Background: Integrated school and home garden interventions can improve health outcomes in low-income countries, but rigorous evidence remains scarce, particularly for school-aged children and to reduce anemia., Objective: We test if an integrated school and home garden intervention, implemented at pilot stage, improves hemoglobin levels among school children (aged 9-13 years) in a rural district in the mid-hills of Nepal., Methods: We use a cluster randomized controlled trial with 15 schools each in the control and treatment groups (n = 680 school children). To test if nutritional improvements translate into a reduction of anemia prevalence, hemoglobin data were collected 6 months after intervention support had ended. Using structural equation modeling, we estimate the direct and indirect effects of the treatment through several pathways, including nutritional knowledge, good food and hygiene practices, and dietary diversity., Results: The integrated school and home garden intervention did not lead to a direct significant reduction in anemia. Causal positive changes of the treatment on nutritional outcomes, although significant, are not strong enough to impact hemoglobin levels. The program improved hemoglobin levels indirectly for children below 12 by increasing the use of good food and hygiene practices at home. These practices are associated with higher hemoglobin levels, particularly for girls, young children, and in households where caregivers are literate., Conclusions: Even integrated school and home garden interventions are not sufficient to reduce anemia among school children. Incorporating behavioral change components around food and hygiene practices into integrated garden interventions is important to unlocking their health impacts.

- Abstract
Background: Discrimination is an important determinant of negative mental health outcomes. This study determined the association between the experience of COVID-19-related discrimination and psychological distress among healthcare workers (HCWs) in Japan., Methods: This cross-sectional study conducted a health survey among 5703 HCWs of six national medical and research centers in Japan from October 2020 to March 2021. COVID-19-related discrimination was defined either when participants or their family members were badmouthed or when they felt discriminated against in some way. We used the Kessler Psychological Distress Scale (K6) to assess the presence of severe psychological distress (≥ 13 points). We used logistic regression models to examine the association between discrimination and psychological distress. We also identified factors associated with discrimination., Results: Of the participants, 484 (8.4%) reported COVID-19-related discrimination and 486 (8.5%) had severe psychological distress. HCWs who were female vs. male (adjusted odds ratio [AOR] = 1.41, 95% confidence interval [CI] = 1.28-1.55), had high vs. low viral exposure (AOR = 2.31, 95% CI = 1.81-2.93), and worked for 11 or more hours/day vs. 8 or less hours/day (AOR = 1.42, 95% CI = 1.35-1.49) were more likely to have experienced COVID-19-related discrimination. The AOR (95% CI) of severe psychological distress was 1.83 (1.29-2.59) among those who experienced discrimination. In the stratified analysis by sociodemographic and job-related factors, all the interactions did not reach statistical significance (p for interaction > 0.20)., Conclusion: Experience of COVID-19-related discrimination was associated with severe psychological distress among HCWs. During the pandemic, effective measures should be taken to prevent the development of negative mental health outcomes in HCWs who experience discrimination., (© 2023. The Author(s).)

- Abstract
Background: In contrast to high-income countries where physical activity (PA), particularly leisure-time PA, has been shown to be protective against hypertension, few studies have been conducted in low- and middle-income countries. We examined the cross-sectional association between PA and hypertension prevalence among rural residents in Vietnam., Methods: We used data collected in the baseline survey of a prospective cohort study, among 3000 people aged 40-60 years old residing in rural Khánh Hòa, Vietnam. Hypertension was defined as systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥ 90 mmHg, or the use of antihypertensive medication. We assessed occupational PA and leisure-time PA using the Global Physical Activity Questionnaire. A robust Poisson regression model was used to investigate the associations, with adjustment for covariates., Results: The prevalence of hypertension was 39.6%. After adjusting for socio-demographic and lifestyle-related variables, leisure-time PA was positively associated with hypertension prevalence (prevalence ratio [PR]: 1.03 per 10 MET-hour/week, 95% confidence interval [CI] 1.01-1.06). Occupational PA was inversely associated with hypertension prevalence (PR: 0.98 per 50 MET-hour/week, 95% CI = 0.96-0.996). After adjusting for BMI and other health-related variables, the association related to occupational PA became statistically non-significant, while the association related to leisure-time PA remained statistically significant., Conclusion: In contrast to previous studies in high-income countries, we found that leisure-time PA was positively associated with hypertension prevalence and occupational PA was associated with a lower hypertension prevalence. This suggests that the association between PA and hypertension might differ depending on the context., (© 2023. The Author(s).)

- Abstract
Background: School-based interventions have been implemented in resource-limited settings to promote healthy dietary habits, but their sustainability remains a challenge. This study identified positive deviants (PDs) and negative deviants (NDs) from the control and treatment groups in a nutrition-sensitive agricultural intervention in Nepal to identify factors associated with healthy dietary practices., Methods: This is an explanatory mixed methods study. Quantitative data come from the endline survey of a cluster randomized controlled trial of a school and home garden intervention in Nepal. Data were analyzed from 332 and 317 schoolchildren (grades 4 and 5) in the control and treatment group, respectively. From the control group, PDs were identified as schoolchildren with a minimum dietary diversity score (DDS) ≥ 4 and coming from low wealth index households. From the treatment group, NDs were identified as schoolchildren with a DDS < 4 and coming from high wealth index households. Logistic regression analyses were conducted to identify factors associated with PDs and NDs. Qualitative data were collected through in-depth phone interviews with nine pairs of parents and schoolchildren in each PD and ND group. Qualitative data were analyzed thematically and integrated with quantitative data in the analysis., Results: Twenty-three schoolchildren were identified as PDs, and 73 schoolchildren as NDs. Schoolchildren eating more frequently a day (AOR = 2.25; 95% CI:1.07-5.68) and whose parents had a higher agricultural knowledge level (AOR = 1.62; 95% CI:1.11-2.34) were more likely to be PDs. On the other hand, schoolchildren who consumed diverse types of vegetables (AOR = 0.56; 95% CI: 0.38-0.81), whose parents had higher vegetable preference (AOR = 0.72; 95% CI: 0.53-0.97) and bought food more often (AOR = 0.71; 95% CI: 0.56-0.88) were less likely to be NDs. Yet, schoolchildren from households with a grandmother (AOR = 1.98; 95% CI: 1.03-3.81) were more likely to be NDs. Integrated results identified four themes that influenced schoolchildren's DDS: the availability of diverse food, the involvement of children in meal preparation, parental procedural knowledge, and the grandmother's presence., Conclusion: Healthy dietary habit can be promoted among schoolchildren in Nepal by encouraging parents to involve their children in meal preparation and increasing the awareness of family members., (© 2023.

- Abstract
Background: Several studies have associated fast eating speed with the risk of general obesity, but there are inadequate data on the association between eating speed and abdominal adiposity which may pose a higher threat to health than general obesity. The present study aimed to investigate the association between eating speed and abdominal obesity in a Vietnamese population., Methods: Between June 2019 and June 2020, the baseline survey of an ongoing prospective cohort study on the determinants of cardiovascular disease in Vietnamese adults was conducted. A total of 3,000 people aged 40-60 years old (1,160 men and 1,840 women) were recruited from eight communes in the rural district of Cam Lam, Khanh Hoa province, in Central Vietnam. Self-reported eating speed was assessed on a 5-point Likert scale, and responses were collapsed into the following three categories: slow, normal, and fast. Abdominal obesity was defined as a waist-to-height ratio of ≥ 0.5. Poisson regression with a robust variance estimator was used to assess the association between eating speed and abdominal obesity., Results: Compared with slow eating speed, the adjusted prevalence ratio (95% confidence interval) for abdominal obesity was 1.14 (1.05, 1.25)1.14 (1.05, 1.25) for normal eating speed and 1.30 (1.19, 1.41) for fast eating speed (P for trend < 0.001)., Conclusion: A faster eating speed was associated with a higher prevalence of abdominal obesity in a middle-aged population in rural Vietnam., (© 2023.

- Abstract
Objectives: While adverse childhood experiences (ACEs) have been shown to be associated with adulthood obesity, less is known about their association with underweight. We examined the associations between parental absence (i.e., a major component of ACEs) and both underweight and excess weight among middle-aged rural community dwellers in Vietnam, where experiences of parental absence was not uncommon during and after the Vietnam War (1955-1975)., Methods: Data came from 3000 middle-aged adults who participated in the baseline survey of Khánh Hòa Cardiovascular Study. Parental absence was defined as parental absence due to death, divorce, or out-migration. Using information on the timing of such events, we categorized participants into those who experienced parental absence before the age of 3, between the ages of 3 and 15, and those without such experiences. BMI was calculated based on measured height and weight (kg/m
2 ) and categorized into three groups: underweight <18.5; normal 18.5-24.9; excess weight ≥ 25. Multinomial logistic regression was then used to investigate the association between parental absence and adult weight status., Results: Parental absence that occurred before the age of 3 was marginally significantly associated with underweight (relative risk ratio [RRR] = 1.44, 95% confidence interval [CI] 0.95, 2.20) but not with overweight/obesity. Parental divorce was associated with overweight/obesity (RRR = 2.48, 95% CI 1.28, 4.81), but not parental absence due to migratory work., Conclusions: While previous studies in Western settings focused almost exclusively on the risk of obesity in relation to exposure to ACEs, our findings point to the potential importance of considering the risk of underweight in low- and middle-income countries., (© 2022 Wiley Periodicals LLC.)- Published

- Abstract
Background: The use of face masks has been associated with physiological changes in body. This study aims to know the changes in pulse rate and blood pressure components after wearing face masks during stairs climbing., Methods: An experimental study was conducted among 60 apparently healthy young adults between 18-35 years of age. The pulse rate and blood pressure of the participants were recorded during rest at ground floor and after climbing the stairs till 5th floor at brisk and regular pace without wearing the face masks. The uniform KN95 masks were distributed and proper coverage of nose, mouth and chin were ensured. After 5 minutes interval, the pulse rate and blood pressure were recorded again at rest in ground floor and after climbing stairs with use of KN95 masks., Results: At rest, the difference in mean pulse rate was statistically significant after wearing masks in participants between 21-25 years of age (86.46±14.59 bpm, p=0.014). After climbing the stairs, the mean pulse rate (131.16±18.48 bpm), mean systolic blood pressure (137.67±16.13 mmHg) and mean rate pressure product (182.87±41.70) were higher in participants (age group: 26-30 years) wearing masks and the difference was statistically significant (p=0.001; 0.013; 0.001respectively). During stairs climbing, the change in mean systolic blood pressure (32.66±16.73 mmHg), mean pulse pressure (43.77±24.64 mmHg) and mean rate pressure product (96.58±37.23) were higher in participants (age group: 26-30 years) and the difference was statistically significant (p=0.036; 0.047 and 0.009 respectively)., Conclusions: The changes in systolic blood pressure, pulse pressure and rate pressure product are found to increase after wearing face masks during stairs climbing. It can be suggestive of increase workload to the heart by wearing face masks in addition to climbing the stairs.

- Abstract
Background: Narrative therapy has been proposed to have practice-based evidence however little is known about its research evidence-base in the treatment of eating disorders. The aim of this study was to conduct a systematic review of the outcome literature of narrative therapy for eating disorders., Method: Treatment outcome data were extracted from 33 eligible included studies following systematic search of five data bases. The study is reported according to Preferred Reporting items for Systematic Reviews and Meta-Analyses guidelines., Results: Of the identified 33 studies, 3 reported positive outcomes using psychometric instruments, albeit some were outdated. Otherwise, reported outcomes were based on therapy transcript material and therapist reports. The most commonly reported treatment outcome was in relation to shifts in identity narratives and improved personal agency with a trend towards under-reporting shifts in ED symptoms. Some improvements were reported in interpersonal and occupational engagement, reduced ED symptoms, and improved quality of life, however, there was an absence of standardized measures to support these reports., Conclusions: This systematic review found limited support for narrative therapy in the treatment of eating disorders through practice-based evidence in clinician reports and transcripts of therapy sessions. Less is known about systematic treatment outcomes of narrative therapy. There is a need to fill this gap to understand the effectiveness of narrative therapy in the treatment of EDs through systematic (1) Deliveries of this intervention; and (2) Reporting of outcomes. In doing so, the research arm of narrative therapy evidence base will become more comprehensively known., (© 2022. The Author(s).)

- Abstract
Background: While parental absence during childhood has been linked to depression/depressive symptoms in adulthood, no research has been conducted on this association in Vietnam, where many children were separated from their parents during and after the Vietnam War (1955-1975). We examined the association between parental absence in childhood and depressive symptoms among rural community dwellers in Khanh Hoa Province, Vietnam., Methods: Data came from 3000 individuals aged 40-60 years old who participated in the baseline survey of the Khanh Hoa Cardiovascular Study. Depressive symptoms were assessed with the 11-item Center for Epidemiologic Studies Depression Scale. Self-reported information on parental absence due to death, divorce, or outmigration to other locations before the age of 15 was also obtained. A Poisson regression analysis with a robust variance estimator was used to examine associations., Results: Experiencing parental absence at 3 - < 15 years old and before 3 years old was associated with a 1.21 times (95% confidence interval [CI] = 1.02-1.43) and 1.41 times (95% CI = 1.15-1.73) higher prevalence of depressive symptoms, respectively (p trend <0.001). When examining the associations by the different reasons for the parental absence, the strongest association was found for parental absence due to outmigration to other locations., Limitations: We had no information on who respondents lived with after they experienced parental absence. In addition, self-reported information on childhood experiences was subject to recall bias., Conclusions: In rural Vietnam, parental absence during childhood was associated with a significantly increased prevalence of depressive symptoms in middle adulthood., (Copyright © 2022 Elsevier B.V.

- Abstract
Neurofibromatosis type 1 is a genetic disorder that follows an autosomal dominant pattern of inheritance. Ocular involvement is not uncommon, but spontaneous dialysis of the retina in the absence of a history of trauma is a rare clinical entity. Rare cases of retinal involvement such as retinal detachment or dialysis of ora serrata could be linked with the abnormal cell-matrix formation in neurofibromatosis type 1. Here, we present a case of a 36-year-old man having Neurofibromatosis Type 1 with spontaneous dialysis of ora serrata without prior history of ocular trauma. A routine fundoscopic examination should be done in addition to the examination of the anterior chamber in patients with neurofibromatosis type 1 despite the absence of ocular complaints., Keywords: case reports; neurfibromatosis type 1; ora serrata; retinal; retinal detachment.

- Abstract
Objective: The association between adult-attained height and risk of colorectal cancer remains elusive among the Japanese population. We performed a systematic review and meta-analysis of epidemiological studies in Japan., Methods: We systematically searched the MEDLINE (PubMed) and Ichushi databases and complemented it with manual search to identify eligible studies. We extracted relative risks or odds ratios from the selected studies and conducted meta-analysis to estimate the summary relative risk with 95% confidence interval. We made the final judgment based on a consensus of the research group members considering both epidemiological evidence and biological plausibility., Results: This systematic review identified four cohort and one case-control studies among the Japanese. The meta-analysis of these five studies showed the summary relative risk of 1.21 (95% confidence interval: 1.07-1.35) of overall colorectal cancer for the highest vs. lowest categories of height. In the analysis by the cancer subsite, the association was significant for colon cancer with a summary relative risk of 1.26 (95% confidence interval: 1.10-1.45) but not for rectal cancer 1.05 (95% confidence interval: 0.71-1.54). In the analysis by sex, tall stature was associated with a significantly increased risk of overall colorectal cancer in both sexes; the summary relative risk was 1.21 (95% confidence interval: 1.04-1.41) in men and 1.20 (95% confidence interval: 1.00-1.44) in women, respectively., Conclusions: The evidence to support that adult-attained height is associated with increased risk of colorectal cancer (colon cancer) among the Japanese population is 'probable'., (© The Author(s) 2021.

- Abstract
Background Since glaucoma-related blindness may only be prevented with early identification and treatment, finding asymptomatic individuals in the target population is critical. It is thus important to determine the awareness and knowledge on glaucoma. Objective To determine the knowledge and awareness on glaucoma among the staff of a tertiary level hospital in central Nepal. Method This was a cross sectional study among the staffs of Dhulikhel Hospital who participated voluntarily in the study. The data was collected through the administration of semi-structured questionnaires. R version 4.0.3 (2020-10-10) was used for the data analysis. Categorical variables are presented as frequency (percentages) and the numerical ones are presented as mean (standard deviation). Adjusted odds ratio (AOR) with 95% confidence interval were estimated through logistic regression analysis for determining factors associated with awareness and knowledge of glaucoma. Result A total of 107 (89.2%) participants had heard about glaucoma of which 93 (86.9%) had good knowledge and 14(13.1%) had poor knowledge on glaucoma. The mean score of knowledge was 64.1±16.9. Only 47.7% of the participants said that glaucoma also has an asymptomatic course. We could not find an association of awareness and knowledge of glaucoma with any of the selected sociodemographic variables. Conclusion Although there was a fairly good glaucoma related awareness and knowledge among hospital staff, we found lack of understanding on some critical issues on glaucoma, mainly related to its asymptomatic nature. There is thus room for improvement in educating about glaucoma even in healthcare settings. Given the necessity of expanding glaucoma awareness in the public, hospital staff might potentially serve as messengers to the communities.

- Abstract
Background Diabetes mellitus is considered as a major public health concern globally. Poor management of diabetes may lead to several serious complications including endstage renal disease, diabetic retinopathy, diabetic neuropathy, and cardiovascular complications. Among them diabetic retinopathy is one of the leading causes of visual impairment and blindness in Nepal. Objective To assess the demographics and level of awareness among individuals with diabetes about diabetic retinopathy during their visit to Department of Ophthalmology at Dhulikhel Hospital. Method A descriptive cross-sectional study was conducted involving all consecutive cases of diabetes mellitus who attended eye clinic with the principal investigator and co-investigator from March 2021 to August 2021. Detailed demographics of the participants, their level of awareness regarding diabetic retinopathy and associated complications were documented. This was followed by a detailed ocular examination intending to screen for the presence of features of diabetic retinopathy. Result A total of 260 patients with a mean age of 54 years ± 12.20 (range of 24 - 85 years) were included. The male to female ratio was 2.2:1. Among them, 65.4% of the patients had diabetes mellitus for less than 5 years duration. Diabetic retinopathy was found in 18.46% of the cases. Awareness of diabetic ocular complications was significantly higher among literate population (p = 0.054), among those who have positive family history of diabetes mellitus (p = 0.529) and those who had undergone prior fundus evaluation (p = 0.000). Conclusion From result of this study, we can emphasize that there is a necessity for health education in order to increase the awareness and knowledge about diabetic retinopathy to lower the burden of sight threatening complications related with the issue.

- Abstract
Background Glaucoma is one of the major causes of irreversible blindness globally. Almost 60 million people globally are affected by glaucoma making it the second leading cause of blindness worldwide. Diagnosis of glaucoma early on is vital for timely management and prevention of blindness. However, it is challenging to diagnose it early because it is asymptomatic in the initial stage, and there is also the dearth of appropriate screening tools. Awareness, knowledge, and beliefs are believed to influence the treatment-seeking behavior of people as well as their uptake of services. Objective To assess the awareness and knowledge about glaucoma among general patients and patient attendants visiting Dhulikhel Hospital. Method We conducted a cross sectional quantitative study among general patients visiting Dhulikhel Hospital. We collected data using face-to-face interviews with semistructured questionnaires. We analyzed data in R version 4.0.3 (2020-10-10). We presented numerical variables as mean and standard deviation whereas categorical variables as frequency and percentage. We determined factors associated with awareness and knowledge of glaucoma using logistic regression analysis and estimated adjusted odds ratio (AOR) with 95% confidence interval. Result Of 379 participants, a total of 214 (56.5%) participants had heard about glaucoma. Out of the participants who heard about glaucoma, the mean knowledge score was 48.3±21.7 and 53.3% had good knowledge on glaucoma. The odds of having heard about glaucoma were two percent lower (AOR=0.98; 95%CI: 0.97-0.99; p-value 0.036) in the older participants compared to one year younger participant, 1.98 (95%CI:1.01-3.86; p-value 0.046) times higher among literates and 2.79 (95%CI: 1.76- 4.41; p-value < 0.001) times among participants with previous ocular examination. The odds of having good knowledge was 1.94 (95%CI: 1.10-3.42; p value 0.021) times among participants with previous ocular examinations. Conclusion The knowledge and awareness regarding glaucoma in a hospital-visiting population in central Nepal was low. Half of the participants were unaware of the disease glaucoma and half of the participants who heard of the glaucoma had poor knowledge on glaucoma.

- Abstract
Food systems in many countries are experiencing a shift from traditional foods toward processed foods high in sugar, fat and salt, but low in dietary fiber and micronutrients. There is an urgent need to better understand drivers of changing food behavior, particularly for lower-income countries. This study analyzes drivers of food choice among children and parents in rural Nepal. It uses qualitative data collected through key informant interviews and focus group discussions with school children, parents and teachers. The study reveals substantial changes in food behavior during the past decade with increased consumption of rice, meat, and highly processed snack foods while an increased consumption of fruit and vegetables is not evident. It identifies cash availability is the main driver of increased rice, meat and snack food consumption. The second driver is the 2015 Nepal earthquake, which accelerated the transition from homegrown food to purchased food as people got habituated to eating more meat and snack foods while reconstruction tripled local wages and changed the food environment. This shows how humanitarian assistance in the wake of extreme shocks can unintentionally contribute to unhealthy eating habits. An integrated school and home garden intervention appears to contribute to healthier diets.

- Abstract
We are now in an era of molecular medicine, where specific DNA alterations can be used to identify patients who will respond to specific drugs. However, there are only a handful of clinically used predictive biomarkers in oncology. Herein, we describe an approach utilizing in vitro DNA and RNA sequencing and drug response data to create TreAtment Response Generalized Elastic-neT Signatures (TARGETS). We trained TARGETS drug response models using Elastic-Net regression in the publicly available Genomics of Drug Sensitivity in Cancer (GDSC) database. Models were then validated on additional in-vitro data from the Cancer Cell Line Encyclopedia (CCLE), and on clinical samples from The Cancer Genome Atlas (TCGA) and Stand Up to Cancer/Prostate Cancer Foundation West Coast Prostate Cancer Dream Team (WCDT). First, we demonstrated that all TARGETS models successfully predicted treatment response in the separate in-vitro CCLE treatment response dataset. Next, we evaluated all FDA-approved biomarker-based cancer drug indications in TCGA and demonstrated that TARGETS predictions were concordant with established clinical indications. Finally, we performed independent clinical validation in the WCDT and found that the TARGETS AR signaling inhibitors (ARSI) signature successfully predicted clinical treatment response in metastatic castration-resistant prostate cancer with a statistically significant interaction between the TARGETS score and PSA response (p = 0.0252). TARGETS represents a pan-cancer, platform-independent approach to predict response to oncologic therapies and could be used as a tool to better select patients for existing therapies as well as identify new indications for testing in prospective clinical trials., (© 2021.

- Abstract
Zinc oxide (ZnO) nanorods incorporated activated carbon (AC) composite photocatalyst was synthesized using a hydrothermal process. The AC was prepared from lapsi ( Choerospondias axillaris ) seed stone, an agricultural waste product, found in Nepal by the chemical activation method. An aqueous suspension of AC with ZnO precursor was subjected to the hydrothermal treatment at 140 °C for 2 h to decorate ZnO rods into the surface of AC. As-obtained ZnO nanorods decorated activated carbon (ZnO/AC) photocatalyst was characterized by various techniques, such as scanning electron microscopy (SEM), X-ray diffraction (XRD), and photoluminescence (PL) spectroscopy. Results showed that highly crystalline hexagonal ZnO nanorods were effectively grown on the surface of porous AC. The photocatalytic property of the as-prepared ZnO/AC composite was studied by degrading methylene blue (MB) dye under UV-light irradiation. The ZnO/AC composite showed better photocatalytic property than that of the pristine ZnO nanorods. The enhanced photocatalytic performance in the case of the ZnO/AC composite is attributed to the combined effects of ZnO nanorods and AC.

- Abstract
School gardens have become a widely used approach to influence children's food knowledge, preferences and choices in low- and high-income countries alike. However, evidence indicates that such programs are more effective at influencing food knowledge and preferences than actual food choices. Such finding may occur because school gardens insufficiently influence the food behavior of parents and because healthy food items are not always available in children's homes. We tested this hypothesis using a one-year cluster randomized controlled trial in Nepal with 15 treatment and 15 control schools and a matched sample of 779 schoolchildren (aged 8-12) and their caregivers. Data were collected before and after the intervention during the 2018-2019 school year. In addition, children's food consumption was monitored using a monthly food logbook. Average treatment effects were quantified with a double-difference estimator. For caregivers, the intervention led to a 26% increase in their food and nutrition knowledge (p < 0.001), a 5% increase in their agricultural knowledge (p = 0.022), a 10% increase in their liking for vegetables (p < 0.001), and a 15% increase in home garden productivity (p = 0.073). For children, the intervention had no discernible effect on food and nutrition knowledge (p = 0.666) but led to a 6% increase in their liking for vegetables (p = 0.070), healthy food practices (p < 0.001), and vegetable consumption (October-December +15%; p = 0.084; January-March +26%; p = 0.017; April-June +26%; p = 0.088). The results therefore indicate both schools and parents matter for nudging children toward healthier food choices., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2020 The Authors.)

- Abstract
Background: Sickle cell and thalassemia are the inherited disorders of globin chain synthesis, and are the most common monogenic disease worldwide. This study aims to find the distribution of hemoglobinopathies (sickle cell and thalassemia) cases in Nepal using laboratory based data., Methods: A retrospective study was carried out at five different sites of Nepal Government that uses capillary electrophoresis for screening of hemoglobin disorders from January 2019 to March 2019. All the cases diagnosed positive for hemoglobinopathy till December 2018 were collected from laboratory record at each sites, and analyzed using Statistical Package for Social Sciences (SPSS version 20.0)., Results: Out of total 4018 patients tested during the period in all five different sites, 1470 were diagnosed positive for hemoglobinopathy. Sickling disorder was the most predominant hemoglobinopathy followed by ?-thalassemia. Province 5, province 6 and province 7 were mostly affected by sickling disorder while the other provinces by ?-thalassemia., Conclusions: Sickle cell is the commonest cause of hemoglobinopathy followed by B thallesmias in Nepalese population. Sickle cell is more concentrated towards western part of Nepal and especially in Tharu ethnic population. In contrast, the distribution of ?-thalassemia is found throughout the country and among all ethnic groups of population.

- Abstract
Background The COVID-19 pandemic has caused lockdown situation impeding all educational institutions including dental colleges. The circumstance demanded online classes as the alternative strategy for continuation of education. Objective To assess current practice and perception about online education among faculties of dental colleges in Nepal. Method A cross-sectional study was conducted among 208 faculties of all dental colleges in Nepal. Data collection was done through structured online questionnaire comprising demographic information, practice and perception of the respondents towards online education. Descriptive statistics surveyed the frequency distribution and Chisquare test assessed the difference in perception among the faculties of different universities. Result The response rate was 74.3%. Faculties commonly used PowerPoint presentation (96.6%) on Zoom platform (83.3%) using laptop (94.7%) with Wi-Fi connection (91.8%). Majority of faculties had good or satisfactory access to internet (94.8%). The faculties believed that the online class environment was interactive (95.2%); but it was not effective (86.5%) as live classroom. Majority of the faculties (79.4%) felt tracking of students' presence was difficult. There was no significant difference on perception towards online class among the faculties of Kathmandu University, Tribhuvan University and BP Koirala Institute Health Sciences at p < 0.05. Conclusion The COVID-19 pandemic has paved the way for e-learning in dental education in Nepal. Faculties agree to complete the theory syllabus and conduct sessional exams as an alternative during the lockdown period. However, they show strong reservations in carrying out practical/clinical simulations and university exams online. Training on e-learning and institutional strategy for online education is recommended.

- Abstract
Background: The Nepal School Meals Program reached 600,000 schoolchildren in basic education in 2017 and plays a key role in the government's strategy to increase children's academic and nutritional outcomes. A large part of the program is implemented through cash transfers with schools responsible for the school meal delivery. Home-grown school feeding, an approach in which local communities are given greater control over the school meals program and part of the food is sourced locally, may strengthen local ownership and improve meal quality, but there is a lack of evidence for impact., Methods: This study piloted home-grown school feeding in 30 schools reaching nearly 4000 children in Sindhupalchok and Bardiya districts in Nepal with the aim to assess operations and outcomes in comparison to the regular cash-based school meals program. The study used a one-time post evaluation with a mixed methods approach. Qualitative data were collected through 12 focus group discussions and 28 key informant interviews with government and school staff, parents, cooks, cooperative members, World Food Programme representatives and other stakeholders involved in the pilot program. The quantitative part applied a quasi-experimental design and used cross-sectional data collected from 1512 children in 30 pilot and 30 control schools., Results: The quantitative data indicated that children in the pilot schools had a significantly higher provision of midday school meals (+ 19%; p < 0.01) and a higher school meal quality in terms of dietary diversity (+ 44%; p < 0.01) and nutritional content (e.g. a 21%-points higher consumption of vitamin A-rich fruit and vegetables; p < 0.01). The qualitative data identified key drivers of these positive outcomes as the use of standard meal options, capacity building of local stakeholders, strengthened community ownership and accountability mechanisms, and local food supply chains. Maintaining the observed gains would require a 20-33% increase in the current budget per school meal in addition to the cost of capacity building., Conclusions: This study for Nepal shows that home-grown school feeding strengthened operations of the school meals program and led to a significantly higher meal provision and quality of school meals.

- Abstract
Background: The School Health and Nutrition (SHN) program is a cost-effective intervention for resource-poor countries. SHN program aims to provide timely support and preventive measures to improve the health of school children, which can be associated with their cognitive development, learning, and academic performance. Stakeholders at different tiers can play significant roles in the program implementation and its success. Their perceptions are equally important to provide information on the factors influencing the implementation process and help to identify the gaps in the process. However, the evidence is scarce on the school health and nutrition policy and program implementation in developing countries. No study has yet explored stakeholders' perceptions on the SHN program implementation process in low-income countries, including Nepal. Therefore, we conducted a qualitative study to explore (1) the SHN program implementation, (2) its impact, and (3) challenges in Nepal., Methods: We conducted a qualitative study through 32 in-depth interviews of the key informants who were actively involved in SHN program implementation in Nepal. The key informants were identified through personal network and snowballing procedure. We adopted a thematic approach for the data analysis., Results: We categorized interview data into three broad themes: (1) SHN program implementation, (2) its impact, and (3) challenges during implementation. Almost all the key informants appreciated the program for its positive impact on students, schools, and communities. The positive impacts included improved students' health and school environment and enhanced community awareness. However, the key impediments in implementing the program included a lack of coordination between stakeholders, lack of resources, limited training opportunities, and doubts regarding the sustainability of the program., Conclusions: This study provided a deeper understanding of the linkage between the SHN program implementation, impact, and challenges in Nepal. Despite the challenges, all the stakeholders acknowledged that the SHN program had positive impacts on students, schools, and communities. Our findings highlighted that stakeholders from all tiers should coordinate, collaborate, and continue their efforts to effectively implement and expand the program nationwide. Awareness campaigns and advocacy for the program are indispensable to pull more resources from relevant stakeholders., Competing Interests: We have obtained the ethical approval from The Research Ethics Committees of the Graduate School of Medicine at the University of Tokyo and Nepal Health Research Council. Written informed consent was obtained from all the key informants.

- Abstract
Introduction: Sagittal jaw relationship is an important parameter for orthodontic treatment planning. Angular and linear measurements both have been proposed and used in orthodontic cephalometrics to assess the sagittal jaw relationships. However, angular measurement has been questioned over the years for its reliability as a result of changes in facial height, jaw inclination and the variable positions of Nasion. So, the objective of our study was to assess the linear anteroposterior jaw relation in a sample of Nepali population using occlusal (Wits appraisal) and palatal planes as reference lines., Methods: A descriptive cross-sectional study was conducted using the lateral cephalogram of 101 individuals visiting the Department of Orthodontics, Kantipur Dental College, Kathmandu, Nepal. Individuals with Class I skeletal relation were selected using convenience sampling method. Radiographs were standardised and traced. Occlusal and palatal planes were drawn that were bisected by the perpendicular lines from Point A and Point B. The linear distances between the intersections were measured to determine sagittal jaw relations., Results: In Nepali individuals with normal ANB angle (3.05°±2.511°), the sagittal jaw relation with reference to occlusal (Wits appraisal) and palatal planes were found to be 0.203±3.343mm and 3.574±4.074mm respectively., Conclusions: Various methods has been proposed and used to assess the sagittal jaw relation and each method has its own strength and limitations. So, it is well advised to use additional cephalometric analysis whenever possible before arriving at any diagnosis and treatment plans.

- Abstract
Introduction: Substance abuse has become a burning issue among the medical and dental students. Dental students, who later transform into dentists, have a significant role in substance abuse cessation. Thus the study was undertaken to quantify substance abuse among dental students of Kantipur Dental College., Methods: A descriptive cross-sectional study was conducted using pretested self-administered questionnaire among undergraduate and post graduate students of Kantipur Dental College. Convenience sampling was done and sample size was calculated., Results: Study revealed 166 (74.10%) as never smokers, 3 (1.30%) as former smokers and 55 (24.60%) as current smokers. Similarly 97 (43.3%) students never used alcoholic drink, 95 (42.41%) consumed alcohol monthly, 29 (12.95%) consumed alcohol 2-4 times a month and 3 (1.34%) consumed alcohol 2-3 times a week. A total of 78 (35%) students used cannabis., Conclusions: Substantial numbers of students were indulged in deleterious habits of smoking, tobacco and cannabis intake. Students need to be properly counselled to discourage substance abuse and create a healthy society.

- Abstract
Background: School health is effective in helping students achieve health literacy, enhance their health-related behaviors, and thereby improve their health status. However, in resource-limited countries, evidence is limited to show the impact of school health. We determined the association of the school health and nutrition (SHN) project activities on students' a) health knowledge, b) hygiene practices, and c) health outcomes, one year after the project completion., Methods: This is a cross-sectional study conducted among the schools with the SHN project and without the project in four districts of Nepal. We recruited 604 students from six schools in the project group and 648 students from other six schools in the comparison group. We used a self-administered questionnaire to collect the data, and analyzed them using regression models and a structural equation model (SEM)., Results: Students from the SHN project group reported the decreased odds of worm infestation (AOR = 0.50, 95% CI: 0.34 to 0.75) and diarrhea/ dysentery infection (AOR = 0.67, 95% CI: 0.47 to 0.97) compared to those in the comparison group. Furthermore, the SEM analysis also showed that the students in the project group were more likely to have better health outcomes (β = 0.03, p< 0.05)., Conclusion: Students in the SHN project group were more likely to have better health outcomes compared to those in the comparison group, even after one year of the project completion. As it can bring about sustainable changes for students, it should be scaled up in other parts of the country., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background Health problems like high body weight and oral diseases have the same essential risk factors as the inflammatory nature of obesity and periodontal disease are widely recognized. Body Mass Index and oral health indices are correlated and may be a confounder of disease status. Objective To assess oral health status and Body Mass Index of school teachers of Kathmandu valley and to find the correlation between them. Method A cross sectional study with purposive sampling was done on 100 Nepalese teachers to assess Body Mass Index, Community Periodontal Index and Decayed Missing Filled Teeth index. Mann-Whitney U-test, crude and adjusted odds ratio were used to analyze the difference between periodontal status based on Community Periodontal Indexscores in relation to age, Body Mass Index, Decayed Missing Filled Teeth. Result The prevalence of periodontal disease according to Community Periodontal Index score was: bleeding on probing 14%, calculus 34%, pocket depth 4-5 mm 35%, pocket depth ≥ 6 mm 12%. The mean Decayed Missing Filled Teeth index was 4.41, and mean number of teeth present was 29.22. According to Body Mass Index score; 10% were underweight, 38% overweight and 2% obese. There were significant differences in age, Body Mass Index and number of teeth present between the control and periodontitis groups. Logistic regression analysis revealed that the risk of periodontal disease increased with age, and there is an increased risk of periodontitis by 39% for each 1 kg/m2 Body Mass Index increase. Conclusion There is increased risk of periodontitis with gain in Body Mass Index in teachers of Kathmandu valley.

- Abstract
Background: TLR8 assists in antiviral approach by producing Type 1 INF via MyD88 dependent IRF7 pathway. However, over expression of INFα/β molecule poses threat by developing tolerance in chronic infection cases and enhancing inflammatory response. Here we report a bi-specific siRNA based complex which differentially activates and silences the TLR8 and MYD88 respectively in a negatively regulated fashion., Results: Outer membrane vesicle from Escherichia coli used for siRNA delivery was observed more efficient when attached with invasive protein Ail along with OmpA (P<0.001) in HEK293-TLR8 cell line. siRNA complexed with p19 protein was efficient in activating TLR8, confirmed by the increment of INFβ molecules (P<0.001) in HEK293-TLR8 compared to its counterpart. Fusion of lipid bilayer of endosomal compartment was significant at pH 4.5 when fusogenic peptides (diINF-7) were incubated in membrane vesicle, thus facilitating the escape of siRNA complex to the host cytoplasm in order to silence MyD88 transcript (P<0.001)., Conclusions: We investigated the activation of TLR8 by bi-specific si-RNA for the production of INFβ. In the same setting we showed that bi-specific si-RNA was able to silence MyD88 transcript in a delayed manner. For the cases of auto immune disease and inflammation where over activation of endosomal TLRs poses serious threat, bi specific siRNA could be used as negative feedback controlled system.

- Abstract
Migratory pastoralism is an adaptation to a harsh and unstable environment, and pastoral herders have traditionally adapted to environmental and climatic change by building on their in-depth knowledge of this environment. In the Hindu Kush Himalayan region, and particularly in the arid and semiarid areas of northern Pakistan, pastoralism, the main livelihood, is vulnerable to climate change. Little detailed information is available about climate trends and impacts in remote mountain regions; herders' perceptions of climate change can provide the information needed by policy makers to address problems and make decisions on adaptive strategies in high pastoral areas. A survey was conducted in Gilgit-Baltistan province of Pakistan to assess herders' perceptions of, and adaptation strategies to climate change. Herders' perceptions were gathered in individual interviews and focus group discussions. The herders perceived a change in climate over the past 10-15 years with longer and more intense droughts in summer, more frequent and heavier snowfall in winter, and prolonged summers and relatively shorter winters. These perceptions were validated by published scientific evidence. The herders considered that the change in climate had directly impacted pastures and then livestock by changing vegetation composition and reducing forage yield. They had adopted some adaptive strategies in response to the change such as altering the migration pattern and diversifying livelihoods. The findings show that the herder communities have practical lessons and indigenous knowledge related to rangeland management and adaptation to climate change that should be shared with the scientific community and integrated into development planning.

- Abstract
Background: 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., Methods: 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., Results: 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)., Conclusion: Our results suggest that students' needs and expectations regarding HIV and sexual health education are not being met through their schools. Moreover, comprehensive information on HIV and sexual health along with increased support and involvement of teachers and parents in sex education might help to improve adolescents' attitudes toward abstinence and intentions for safer sex. Adapting future school-based interventions to incorporate such elements may thus be an effective strategy to promote adolescent sexual health.

- Abstract
Background: Ischemic mitral regurgitation is a frequent complication of acute coronary syndrome. It primarily occurs in patients with a prior myocardial infarction but also may be seen with acute ischemia, a setting in which the MR typically resolves after the ischemia resolves. The vast majority of patients have "functional" ischemic MR. In these individuals, the papillary muscles, chordae, and valve leaflets are normal. However, the leaflets do not coapt and restricted leaflet motion is frequently noted on echocardiography. Ischemic mitral regurgitation indicates a poor prognosis after acute myocardial infarction. This study addresses the clinical characteristics of patients of acute coronary syndrome with mild functional ischemic mitral regurgitation and its impact on immediate in-hospital cardiovascular outcomes and death., Patients and Methods: From March 2006 through May 2007, patients who underwent 2-dimensional (2D) color doppler echocardiographic quantification of ischemic mitral regurgitation within 10 days of admission for acute coronary syndrome (ACS) in Manipal Teaching Hospital, a tertiary hospital in the western region of Nepal were noted. The demographic details, conventional risk factors of coronary artery disease, clinical and laboratory findings, treatment course and in-hospital outcomes of all the patients with mild functional ischemic MR following ACS in that time duration were recorded in a designated Performa. A total of 94 patients enrolled in the study were divided into two groups: Group I with mild functional ischemic MR and Group II without MR on 2D echocardigraphic assessment. Patient characteristics, risk factors, ejection fraction, and cardiovascular outcome and death among the two groups were compared and analyzed using software package SPSS 17.0 version., Results: Group I constituted 64.89% of the study population and Group II comprised of 35.11%. The patients in Group I was more likely to be elderly diabetic (P<0.05), and smokers with hypertension (P < 0.05). Mild functional ischemic MR was more common in patients with STEMI as compared to those with unstable angina and NSTEMI (55.7%, 36.1%, and 8.2%; P < 0.05).The mean ejection fraction in the first group was 54.84% in contrast to 58.92% observed in group II (P < 0.05).The type of wall involvement inferred from EKG analysis was homogeneously distributed in both the groups. Finally, there was no difference in immediate in-hospital (within 10 days) mortality or cardiovascular outcomes (heart failure, ventricular tachycardia/fibrillation, hypotension, and cardiogenic shock) between these two groups., Conclusion: Ischemic mitral regurgitation following acute coronary syndromeare more likely in elderly diabetics and hypertensive smokers. It is a more common finding in STEMI. Although mild MR following ACS does reduce ejection fraction, the immediate (within 10 days) in-hospital mortality and cardiovascular outcomes are not significantly altered.

- Abstract
The purpose of this study was to find out the prevalence and antibiotic sensitivity pattern of Salmonella typhi and paratyphi isolated from children presenting with fever at Kanti Children's Hospital in Kathmandu, Nepal. A total of 9,856 blood samples collected for culture during one year period (April 2007 to March 2008) were included in the study. Out of total, 235 (2.0%) were positive for S. typhi and paratyphi A. Of the total positive, 195 (83.0%) were S. typhi and 40 (17.0%) were S. paratyphi A. The growth positive rate in two genders (M: 53.2% and F: 46.8%) was not significant (P > 0.05). Over two-third of cases were clustered in the age-group of 1-10 years. The occurrence of infections was common in summer months (rainy season). S. typhi was found to be most sensitive to cefotaxime (100.0%) followed by ceftriaxone (98.9%), ofloxacin (93.5%), cotrimoxazole (93.5%) and chloramphenicol (93.2%) and was least sensitive to amoxyccilin (66.7%) followed by ciprofloxacin (86.6%). S. paratyphi also was found to be most sensitive to cefotaxime (100.0%), followed by ceftriaxone (97.4%), cotrimoxazole (97.1%) and chloramphenicol (92.5%) and was least sensitive to amoxycillin (15.0%) followed by ciprofloxacin (51.3%) and ofloxacin (70.3%).

- Abstract
A retrospective study was conducted to find out the causative agents of urinary tract infection (UTI) in children and their antibiotic sensitivity pattern among Nepalese children. This was done at Kanti Children's Hospital in Kathmandu (Nepal) by analyzing the records of urine samples collected for culture and sensitivity tests over a period of six months (April to November, 2007). Of the total 1878 mid-stream urine samples collected from suspected cases of UTI, 538 (28.6%) were positive for pathogenic organisms. There was no significant difference in growth positive rate in two genders (M: 51.7% and F: 48.3%). Of the various pathogenic organisms isolated, Escherichia coli constituted for 93.3% followed by Proteus sp, Klebsiella sp, Citrobacter sp, Staphylococcus aureus and others. E. coli was found to be most sensitive to amikacin, chloramphenicol, nitrofurantoin and ofloxacin and least sensitive to most commonly used drugs like cephalexin, nalidixic acid, cotrimoxazole and norfloxacin.

- Abstract
Internuclear distances derived from paramagnetic relaxation enhancement (PRE) data were used to restrain molecular dynamics simulations of the intrinsically unstructured transactivation domain of the tumor suppressor protein, p53. About 1000 structures were simulated using ensemble averaging of replicate molecules to compensate for the inherent bias in the PRE-derived distances. Gyration radii measurements on these structures show that the p53 transactivation domain (p53TAD) is statistically predominantly in a partially collapsed state that is unlike the open structure that is found for p53TAD bound to either the E3 ubiquitin ligase, MDM2, or the 70 kDa subunit of replication protein A, RPA70. Contact regions that potentially mediate the collapse were identified and found to consist of mostly hydrophobic residues. The identified contact regions preferentially place the MDM2 and RPA70 binding regions in close proximity. We show that our simulations thoroughly sample the available range of conformations and that a fraction of the molecules are in an open state that would be competent for binding either MDM2 or RPA70. We also show that the Stokes radius estimated from the average gyration radius of the ensemble is in good agreement with the value determined using size exclusion chromatography. Finally, the presence of a persistent loop localized to a PXP motif was identified. Serine residues flanking the PXP motif become phosphorylated in response to DNA damage, and we postulate that this will perturb the equilibrium population to more open conformations.

- Abstract
The Clean Development Mechanism (CDM) under the Kyoto Protocol to the United Nations Framework Convention on Climate Change is considered a key instrument to encourage developing countries' participation in the mitigation of global climate change. Reduction of greenhouse gas (GHG) emissions through the energy supply and demand side activities are the main options to be implemented under the CDM. This paper analyses the general equilibrium effects of a supply side GHG mitigation option-the substitution of thermal power with hydropower--in Thailand under the CDM. A static multi-sector general equilibrium model has been developed for the purpose of this study. The key finding of the study is that the substitution of electricity generation from thermal power plants with that from hydropower plants would increase economic welfare in Thailand. The supply side option would, however, adversely affect the gross domestic product (GDP) and the trade balance. The percentage changes in economic welfare, GDP and trade balance increase with the level of substitution and the price of certified emission reduction (CER) units.

- Abstract
Foot and mouth disease (FMD) causes substantial economic losses to the predominantly agricultural community of the Kingdom of Nepal. FMD is endemic in the country and four of the seven serotypes of FMD virus have been isolated (O, A, C and Asia 1). The epidemiology of FMD and the factors which play a role in its prevalence and spread are outlined. The National Epidemiological Laboratory for FMD has been established in Kathmandu and its diagnostic capabilities and activities are described. The important points to be considered in the formulation of any future regional or national control programme for FMD in Nepal are discussed.

- Abstract
Anthropometric methods involving measurement of weight-for-height, height-for-age, weight-for-age, and mid-upper arm circumference have been extensively researched to identify an appropriate method of monitoring infant and child growth. Many countries have adopted weight for age as the main practical method. The Malawi Ministry of Health introduced weight for age based upon WHO recommended standards as a growth indicator in 1973. There are, however, difficulties in making the practice widely used at community level. In the present study, confined to the four urban areas of Malawi, a comparison was made between the weight-for-age (W/A) and mid-upper arm circumference (MUAC) measurements. A very good correlation was observed between the two methods of screening for identification of undernourished children from 4 months of age onwards. Correct use of MUAC was found to be as effective as W/A in detecting undernutrition.
