Objectives To understand the impact of the international medical elective (IME) on Nepali patients and physicians alongside visiting European and American medical students. Methods At a hospital in Nepal, semi-structured interviews were conducted with 15 patients and 15 physicians about positive and negative experiences with visiting medical students. Likert scale surveys about knowledge of Nepal, clinical competencies, and post-elective feedback were administered to 56 visiting medical students before and after their elective. Interviews were coded using conventional content analysis and surveys were analyzed using descriptive statistics and paired t-tests. Results Emergent positive themes from interviews were that visiting students enhanced the reputation of the hospital, afforded financial benefits, improved international collaboration, and increased knowledge, culture and language exchange. However, negative themes were the language barrier and time expended to orient students. Before vs. after the elective, visiting students had increased knowledge of Nepal's healthcare system (M=1.9, SD=0.6 vs. M=3.2, SD=0.6, t(55)=-10.22, p

Background Hypertension and headache disorders are major contributors to public ill health, linked by a long-standing but questionable belief that hypertension is a conspicuous cause of headache. In Nepal, where hypertension is common and often untreated, we assessed the substance of this belief, hypothesising that, should hypertension be a significant cause of headache, a clear positive association between these disorders would exist. Methods In a cross-sectional, nationwide study, trained health workers conducted face-to-face structured interviews, during unannounced home visits, with a representative sample of the Nepalese adult population (18–65 years). They applied standard diagnostic criteria for headache disorders and measured blood pressure digitally. Hypertension was defined as systolic pressure ≥140 and/or diastolic ≥90 mm Hg. Results Of 2,100 participants (59.0% female, mean age 36.4 ± 12.8 years), 317 (15.1%) had hypertension (41.0% female) and 1,794 (85.4%) had headache (61.6% female; 728 migraine, 863 tension-type headache, 161 headache on ≥15 days/month [mutually exclusive diagnoses]; 42 unclassified headaches). All headache collectively was less prevalent among hypertension cases (78.9%) than non-cases (86.6%; p = 0.001). A negative association between hypertension and all headache was demonstrated in bivariate analysis (odds ratio: 0.6 [95% Confidence interval: 0.4–0.8]; p Conclusions If any association exists between hypertension and headache disorders, it is negative. From the public-health perspective, headache disorders and hypertension are unrelated entities: they need distinct policies and programs for prevention, control and management.

Given the scarcity of data on diabetes prevalence and associated risk factors among women in rural Nepal, we aimed to examine this, using glycated hemoglobin (HbA1c) as a diagnostic tool. A cross-sectional survey addressing reproductive health and non-communicable diseases was conducted in 2012–2013 among non-pregnant, married women in Bolde, a rural district of Nepal. HbA1c ≥ 6.5% (48 mmol/mol) was used as diagnostic criterion for diabetes, a cut-off of 7.0% (53 mmol/mol) was used to increase the specificity. HbA1c was measured in 757 women (17–86 years). The prevalence of diabetes and prediabetes was 13.5% and 38.5%, respectively. When using 7.0% as a cut-off, the prevalence of diabetes was 5.8%. Aging, intake of instant noodles and milk and vegetarian food (ns) were associated with increased risk for diabetes. Waist circumference was higher among women with diabetes, although not significant. The women were uneducated (87.6%), and only 12% had heard about diabetes. In conclusion, we observed a higher prevalence of diabetes and prediabetes than anticipated among rural, Nepalese women. The increased risk was mainly attributed to dietary factors. In contrast to most previous studies in Nepal, we used HbA1c as diagnostic criterion.

Hypovitaminosis D is prevalent worldwide, and especially in South-Asia. According to the Institute of Medicine (IOM), 25(OH)D levels below 30 nmol/L are defined as vitamin D deficiency (VDD) and levels between 30–50 nmol/L as insufficiency (VDI). Besides its role in calcium homeostasis, it has been postulated that vitamin D is involved in metabolic syndrome. Given the scarcity of data on vitamin D status in Nepal, we aimed to examine the prevalence of VDD and VDI, as well as the determinants and association with metabolic parameters (lipids, HbA1c), in a cohort of women in rural Nepal. Altogether, 733 women 48.5 ± 11.7 years of age were included. VDD and VDI were observed in 6.3 and 42.4% of the participants, respectively, and the prevalence increased by age. Women reporting intake of milk and eggs > 2 times weekly had higher 25(OH)D levels than those reporting intake < 2 times weekly. Women with vitamin D levels < 50 nmol/L displayed higher levels of cholesterol, LDL-cholesterol, triglycerides, and HbA1c. Additionally, a regression analysis showed a significant association between hypovitaminosis D, dyslipidemia, and HbA1c elevation. In conclusion, VDI was prevalent and increased with age. Milk and egg intake > 2 times weekly seemed to decrease the risk of VDI. Moreover, hypovitaminosis D was associated with an adverse metabolic profile.

Background In South Asia, data on enteric fever are sparse outside of urban areas. We characterized enteric fever diagnosis patterns and the burden of culture-confirmed cases in peri-urban and rural Nepal. Methods We used national reports to estimate enteric fever diagnosis rates over 20 years (1994–2014) and conducted a prospective study of patients presenting with a >72-hour history of fever to 4 peri-urban and rural healthcare facilities (during August 2013–June 2016). We compared clinical characteristics of patients with culture-confirmed Salmonella Typhi or Paratyphi infection to those of patients without enteric fever. We used generalized additive models with logistic link functions to evaluate associations of age and population density with culture positivity. Results National rates of enteric fever diagnosis were high, reaching 18.8 cases per 1000 during 2009–2014. We enrolled 4309 participants with acute febrile illness. Among those with a provisional clinical diagnosis, 55% (1334 of 2412) received a diagnosis of enteric fever; however, only 4.1% of these had culture-confirmed typhoidal Salmonella infection. Culture positivity was highest among young adults and was strongly associated with higher population density (P < .001). Conclusions Enteric fever diagnosis rates were very high throughout Nepal, but in rural settings, few patients had culture-confirmed disease. Expanded surveillance may inform local enteric fever treatment and prevention strategies.

Background Cardiovascular disease represents the largest burden on global health, important modifiable risk factor being hypertension. Difference in response to antihypertensive medication depending on ethnic group is well recognized. There is very few data regarding this difference in the South Asian population especially from Nepal.Objective The aim of this study is to find out which antihypertensive medication has better efficacy in our population.Method One seventy two newly diagnosed hypertensive patients who presented to cardiology OPD were included. Blood Pressure (BP) was recorded in both arms at least three times. Patients were counseled for lifestyle and dietary modification and were prescribed one of the three drugs Hydrochlorthiazide 25 mg or Amlodipine 5 mg or Enalapril 5 mg. Patients were called back in 4-6 weeks time and Blood Pressure was recorded in similar manner.Result Out of 172 patients, 97 were male and 75 female. The mean age was 55.49±1.03 years. Mean Systolic BP before treatment was 156.2±10.6 mm of Hg and Mean Diastolic BP before treatment was 100.5 ±6.8 with no statistically significant difference among different groups. However Systolic BP reduction was 14.6 ±5.1, 21.9±5.9 and 21.8±7.4 by Hydrochlorthiazide , Amlodipine and Enalapril respectively. Diastolic BP reduction was 8.8±2.5, 14.2±2.8 and 14.3±2.9 by Hydrochlorthiazide, Amlodipine and Enalapril respectively.Conclusion Amlodipine and Enalapril are equally effective in controlling BP in our population. Hydrochlorthiazide is less effective than both Amlodipine and Enalapril.

Background There is a need to develop sustainable emergency health care systems in low-resource settings, but data that analyses emergency health care needs in these settings are scarce. We aimed at assessing presenting complaints (PCs) and post-discharge mortality in a large emergency department population in Nepal. Methods Characteristics of adult patients who entered the emergency department (ED) in a hospital in Nepal were prospectively recorded in the local emergency registry from September 2013 until December 2016. To assess post-ED mortality, patient households were followed-up by telephone interviews at 90 days. Results In 21892 included adults, the major PC categories were injuries (29%), abdominal complaints (23%), and infections (16%). Median age was 40 years and sex distribution was balanced. Among 3793 patients followed at 90 days, 8% had died. For respiratory and cardiovascular PCs, 90-day mortality were 25% and 23%. The highest mortality was in individuals with known chronic lung disease, in this group 32% had died by 90 days of ED discharge, regardless of PC. In women, illiteracy compared to literacy (adjusted odds ratio (aOR) = 7.0, 95% confidence interval (CI) = 2.1-23.6) and being both exposed to tobacco-smoking and traditional cooking stove compared to no smoke (aOR = 2.8, 95% CI = 1.6-4.9) were associated with mortality. The mortality was much higher among family-initiated discharged patients (17%, aOR = 5.4, 95% CI = 3.3-8.9) compared to doctor-initiated discharged (3%). Conclusions Our report suggests that nearly one in ten patients seeking emergency health care died within 90 days. This finding is alarming and novel. Post-discharge studies need to be replicated and appropriate follow-up programs in low-resource settings where primary health care is underdeveloped are urgently needed. © Author(s) 2019.

Objective The purpose of this study was to translate, cross-culturally adapt, and assess the reliability and validity of the Pelvic Girdle Questionnaire (PGQ) in pregnant Nepalese women. Methods The cross-cultural adaptation process was conducted according to the Guillemin guidelines. Reliability and validity were assessed using cross-sectional design. The participants responded to questionnaires of sociodemographics, the Nepali version of the PGQ, the Oswestry Disability Index, the Patient-Specific Functional Scale, the 5-item version of the Edinburgh Depression Scale, and the Numerical Pain Rating Scale. The internal consistency was assessed with Cronbach's alpha. The test–retest reliability was calculated using the intraclass correlation coefficient and smallest detectable change. Construct validity was assessed by testing 9 a priori hypotheses that examine correlations between the PGQ activity and symptom subscales, and also among the PGQ subscales and Oswestry Disability Index, Numerical Pain Rating Scale, Patient-Specific Functional Scale, and 5-item version of the Edinburgh Depression Scale. Spearman and Pearson's correlation were used to assess the correlations. Results A sample of 111 pregnant women were included in the study. The Cronbach's alpha for the Nepali version of the total PGQ was good (α = 0.83), and the test–retest reliability was acceptable (ICC2.1, 0.72) with a measurement error of SDC95% 18.6 points. Seven of the 9 hypotheses found support, which confirms acceptable construct validity of the Nepali PGQ. Conclusion The Nepali version of the PGQ is a reliable and valid tool for assessing pelvic girdle pain in pregnant Nepalese women.

Objectives: The aim of this study was to explore positive and negative preferences towards problem-based learning in relation to personality traits and socio-cultural context. Method: The study was an anonymous and voluntary crosssectional survey of medical students (N=449) in hybrid problem-based curricula in Nepal, Norway and North Dakota. Data was collected on gender, age, year of study, cohabitation and medical school. The PBL Preference Inventory identified students’ positive and negative preferences in relation to problem-based learning; the personality traits were detected by the NEO Five-Factor Inventory. The determinants of the two kinds of preferences were analyzed by hierarchical multiple linear regressions. Results: Positive preferences were mostly determined by personality; associations were found with the traits Extraversion, Openness to experience, Conscientiousness and Neuroticism; the first three are related to sociability, curiosity and orderliness, the last, to mental health. The learning environments of such curricula may be supportive for some and unnerving for others who score high on Neuroticism. Negative preferences were rather determined by culture, but also, they correlated with Neuroticism and Conscientiousness. Negative preferences were lower among females and students living in symmetrical relationships. Some high on Conscientiousness disliked group work, and the negative correlation with Agreeableness indicated that less sociable students were not predisposed to this kind of learning activity. Conclusions: Preferences related to problem-based learning were significantly and independently determined both by personality traits and culture. More insights into the nature of students’ preferences may guide aspects of curriculum modifications and the daily facilitation of groups.

Introduction Natural disasters pose a great challenge to the health systems and individual health facilities. In low-resource settings, disaster preparedness systems are often limited and not been well described. Two devastating earthquakes hit Nepal within a 17-days period in 2015. This study aims to describe the burden and distribution of emergency cases to a local hospital. Methods This is a prospective observational study of patients presenting to a local hospital for a period of 21 days following the earthquake on April 25, 2015. Demographic and clinical information was prospectively registered for all patients in the systematic emergency registry. Systematic telephone interviews were conducted in a random sample of the patients 90 days after admission to the hospital. Results A total of 2,003 emergency patients were registered during the period. The average daily number of emergency patients during the first five days was almost five times higher (n = 150) than the pre-incident daily average (n = 35). The majority of injuries were fractures (58%), 348 (56%) in the lower extremities. A total of 345 surgical procedures were performed and the hospital treated 111 patients with severe injuries related to the earthquake (compartment syndrome, crush injury, and internal injury). Among those with follow-up interviews, over 90% reported that they had been severely affected by the earthquakes; complete house damage, living in temporary shelter, or loss of close family member. Conclusion The hospital experienced a very high caseload during the first days, and the majority of patients needed orthopaedic services. The proportion of severely injured and in-hospital deaths were relatively low, probably indicating that the most severely injured did not reach the hospital in time. The experiences underline the need for robust and easily available local health services that can respond to disasters. © 2018 Giri et al.

Objective This study aimed to evaluate if domestic violence affected women’s ability to prepare for childbirth. Birth preparedness and complication readiness (BP/CR) includes saving money, arranging transportation, identifying a skilled birth attendant, a health facility, and a blood donor before childbirth. During data collection, Nepal experienced two earthquakes and therefore it was possible to examine associations between domestic violence, women’s BP/CR and effects of the earthquakes. Methods Women who were between 12 and 28 weeks of gestation participated in a descriptive cross-sectional study at a hospital antenatal clinic in Nepal, where they completed a structured questionnaire on sociodemographic characteristics, obstetric history, experiences of domestic violence, and BP/CR. The 5-item Abuse Assessment Screen was used to assess prevalence of domestic violence, and a questionnaire on safe motherhood obtained from Jhpiego was used to assess BP/CR status. The participants self-completed the questionnaire on a tablet computer. Those who reported at least three out of five BP/CR activities were considered prepared for childbirth. Results A total of 1011 women participated in the study: 433 pre-earthquakes and 578 post-earthquakes. With respect to BP/CR, 78% had identified a health facility for childbirth and 65% had saved money prior to childbirth. Less than 50% had identified a birth attendant to assist with the delivery, transportation to a health facility, or arranged for a potential blood donor. Prior to the earthquakes, 38% were unprepared; by contrast, almost 62% were not prepared after the earthquakes. A significant association was found between exposure to violence and not being prepared for childbirth (AOR = 2.3, 95% CI: 1.4–3.9). The women with increased odds of not being prepared for childbirth were illiterate (AOR = 9.9, 95% CI:5.7–17), young (AOR = 3.4, 95% CI:1.6–7.2), from the most oppressed social classes (AOR = 3.0, 95% CI:1.2–7.6), were married to illiterate husbands (AOR = 2.5, 95% CI:1.2–5.2), had attended fewer than four antenatal visits (AOR = 2.0, 95% CI: 1.4–2.6), had low incomes (AOR = 1.7, 95% CI:1.1–2.9) or lived in rural settings (AOR = 1.5, 95% confidence interval CI:1.2–2.1). Conclusion The paper identifies vulnerable women who require extra care from the health system, and draws attention to the need for interventions to reduce the harmful effects of domestic violence on women’s preparations for childbirth. © 2018 Pun et al.

Background Infections with soil-transmitted helminths and pathogenic intestinal protozoa pose a considerable public health burden, particularly in low- and middle-income countries, including Nepal. We assessed the extent of intestinal parasite infections among schoolchildren in two districts of Nepal and determined underlying risk factors. Methods A cross-sectional survey was conducted between March and May 2015 in the districts of Dolakha and Ramechhap, Nepal. A total of 708 children, aged 8–16 years from 16 purposively selected schools, were enrolled. Each child provided a single stool sample that was subjected to a suite of copro-microscopic diagnoses for intestinal protozoa and helminths. Drinking water samples from different sources at schools (n = 29), community places (n = 43) and households (n = 562) were analysed for contamination with thermotolerant coliforms (TTC). A questionnaire was administered to determine individual- and household-level risk factors of intestinal parasite infections. Self-reported symptoms were assessed and a clinical examination was undertaken by a physician. Haemoglobin was measured and used as a proxy for anaemia. Mixed logistic regression models were applied to investigate associations. Results The overall prevalence of intestinal parasite infections was 39.7%. Trichuris trichiura (30.9%), Giardia intestinalis (30.5%) and hookworm (30.2%) were the predominant intestinal parasite infections. Children from households lacking soap for handwashing were at higher odds of intestinal parasite infections than children who had soap [adjusted odds ratio (aOR) 1.81; 95% confidence interval (CI): 1.13–2.89; P = 0.01]. Children from households without freely roaming domestic animals showed lower odds of G. intestinalis compared to children from households with freely roaming animals (aOR 0.52; 95% CI: 0.33–0.83; P = 0.01). One out of three (31.0%) children suffered from fever and 22.4% had watery diarrhoea within a two-week recall period. Anaemia was diagnosed in 23.6% of the children. Water contamination with TTC showed no clear association with intestinal parasite infection. Conclusions Intestinal parasites are common among schoolchildren in the two surveyed districts of Nepal. An important risk factor was lack of soap for handwashing. Our findings call for efforts to control intestinal parasite infection and emphasis should be placed on improvements in water, sanitation and hygiene interventions.

Background Peer leadership is widely recognized as an effective approach to health promotion and empowerment among people of similar ages, especially the youth. Such programs build peer leaders who in turn help empower the youths in their groups to improve their health and life skills related to health. Most previous studies have focused on the effectiveness of such activities in target groups but have neglected to effectively address and explore the transformations in peer leaders themselves. Objectives This descriptive study aimed to investigate the level of social change and health consciousness among student peer leaders in three Youth health promotion programs in Thailand: Friend’s Corner, Smart Consumer and Volunteer Minded Young Dentists, and to compare them with the general students. Methods The study was conducted using a self-administered questionnaire, which was developed based on Tyree’s Social Change Model of leadership, Gould’s concept and Dutta-Bergman’s concept. The study population comprised of 11th grade students (N=660) from Kalasin Province in Thailand, 320 of whom were peer leaders. Results The findings revealed that the peer leaders scored higher than non peer leaders in all domains. Among the peer leaders, it was found that Volunteer Minded Young Dentists group had the highest scores in “controversy with civility”, “social change agent” characteristics, “holistic health perceptions” and “responsibility for one’s own health” regarding health consciousness. Conclusion The results of this study confirmed that the peer leadership approach can help young people to develop life skills through social transformation and increase health consciousness for better status of health in the community.

Background Radiation is a necessary evil in Coronary Angiogram. The Interventional Cardiology procedure provides huge benefit to the patient but at the cost of radiation. There is evidence of cumulative effect of radiation. Therefore it is essential to keep the radiation dose as minimum as possible. Objective The aim of this study is to find out radiation exposed to the patient undergoing diagnostic coronary angiogram. Method A retrospective study was done. Those patients who underwent diagnostic coronary angiogram were selected for the study. There were total of 166 patients. Radiation exposure in terms of fluoroscopy time in minute and dose area product (DAP) in Gy.cm2 was recorded. Result Out 166 patients 92 were male and 74 female. Age range was from 39 to 79 years with mean age 58.13±9.14. Amount of contrast used was in range of 30 to 100 ml with mean of 45.54±14.06. Range of fluoroscopy time was 2.60 to 37.00 minutes with mean 11.38±6.80. Mean fluoroscopy time in male was 10.92±5.82 minutes and in females it was 11.92±7.68 minutes, with p 0.331. The range of DAP was 11.00 Gy.cm2 to 106.00 Gy.cm2 with mean 40.73±23.58 Gy.cm2. The mean DAP in male and female was 38.77±23.26 Gy.cm2 and 43.16±23.90 Gy.cm2 respectively with p 0.234. Conclusion From this study we can conclude that the radiation exposure to our patient undergoing coronary angiogram is similar to the international values in terms DAP but more in terms of fluoroscopy time. When males and females compared there is no difference. Kathmandu University Medical Journal Vol.13(1) 2015; 61-63

Background Hypertension is a cardiovascular disorder rapidly emerging as a major public health problem in developing countries and is the most widely recognized modifiable risk factor for cardiovascular diseases. Objective The objective of this study was to find out the prevalence and associated risk factors with hypertension among people aged 50 years and more in Banepa Municipality, Kavre, Nepal. Methods It is a cross- sectional, population based study which was carried out in Banepa Municipality from May 15 to June 15, 2009. Among total 11 wards of Banepa municipally, wards number 1, 3, 5, 6, 7, and 10 were selected by using Simple Random Sampling Technique and 405 subjects of people aged 50 years and more were selected for study from the selected wards by using Cluster Sampling. The structured interview method was used for collection of data. Mercury sphygmomanometers with standard cuff were used to measure the indirect auscultatory arterial blood pressure. Two consecutive blood pressure readings were taken and average of them was calculated to determine single value of blood pressure. Results The prevalence of hypertension was 44.9 percent (47.75% in male and 42.73% in females). Among them, only 32.9 percent (60/182) were previously diagnosed as hypertension. The higher proportion of hypertensive cases were in age > 65 years (55.49%) than in the age group < 65 years (36.32%). The prevalence of hypertension was seen positively associated with non vegetarian eating habits, alcohol consumption, and > 25 Body max index. Taking green leafy vegetable at least once a week was negatively associated with the prevalence of the hypertension. Conclusion These findings provide important information on the prevalence, associated factors of hypertension in Banepa Municipality. Effective public health measures and strategies are needed to improve prevention, diagnosis and access to treatment of these 50 years and above population.

Background The oxygen saturation of haemoglobin is reduced in high altitude-living organisms. Increase in the hematocrit is responsible for rise in the hemoglobin concentration so that the oxygen carrying capacity in the hypobaric hypoxic subject is elevated. Objectives To compare two different high altitude populations, in order to study the relationship between arterial oxygen saturation and hematocrit. Methods lIn the cross-sectional study of two populations residing at altitude of 2800 m and 3760 m are compared for the difference in hematocrit. The oxygen carrying capacity of arterial haemoglobin (SaO2) is determined by pulse oximetry. The sample is drawn from the natives of two small villages, Thini at Jomsom (2800 m) and Jharkot (3760 m) in Mustang district of Nepal. The natives at 2800 m are termed as lower high altitude population and local residents at 3760 m are said to be higher altitude population in this study. The sample blood was drawn by venipuncture and packed cell volume was determined by Wintrobe’s method. Results The hematocrit obtained from 3760 m altitude population and the lower high altitude population at altitude of 2800 m differ significantly with the p value < 0.0001and the SaO2 in both the population fails to show any difference with p value > 0.05. Deep breathing exercise in these populations however increased SaO2 significantly. Conclusion The higher altitude natives have greater arterial oxygen saturation than lower altitude population which is due to rise in red cell concentration. The slow deep breathing raises oxygen saturation irrespective of altitude.

This study assessed drinking water quality, sanitation, and hygiene (WASH) conditions among 708 schoolchildren and 562 households in Dolakha and Ramechhap districts of Nepal. Cross-sectional surveys were carried out in March and June 2015. A Delagua water quality testing kit was employed on 634 water samples obtained from 16 purposively selected schools, 40 community water sources, and 562 households to examine water quality. A flame atomic absorption spectrophotometer was used to test lead and arsenic content of the same samples. Additionally, a questionnaire survey was conducted to obtain WASH predictors. A total of 75% of school drinking water source samples and 76.9% point-of-use samples (water bottles) at schools, 39.5% water source samples in the community, and 27.4% point-of-use samples at household levels were contaminated with thermo-tolerant coliforms. The values of water samples for pH (6.8–7.6), free and total residual chlorine (0.1–0.5 mg/L), mean lead concentration (0.01 mg/L), and mean arsenic concentration (0.05 mg/L) were within national drinking water quality standards. The presence of domestic animals roaming inside schoolchildren’s homes was significantly associated with drinking water contamination (adjusted odds ratio: 1.64; 95% confidence interval: 1.08–2.50; p = 0.02). Our findings call for an improvement of WASH conditions at the unit of school, households, and communities.

We developed a food frequency questionnaire (FFQ) designed to measure the dietary practices of adult Nepalese. The present study examined the validity and reproducibility of the FFQ. To evaluate the reproducibility of the FFQ, 116 subjects completed two 115-item FFQ across a four-month interval. Six 24-h dietary recalls were collected (1 each month) to assess the validity of the FFQ. Seven major food groups and 23 subgroups were clustered from the FFQ based on macronutrient composition. Spearman correlation coefficients evaluating reproducibility for all food groups were greater than 0.5, with the exceptions of oil. The correlations varied from 0.41 (oil) to 0.81 (vegetables). All crude spearman coefficients for validity were greater than 0.5 except for dairy products, pizzas/pastas and sausage/burgers. The FFQ was found to be reliable and valid for ranking the intake of food groups for Nepalese dietary intake.

To determine the population distribution of cardiovascular risk in eight low- and middle-income countries and compare the cost of drug treatment based on cardiovascular risk (cardiovascular risk thresholds ≥ 30%/≥ 40%) with single risk factor cutoff levels.Using World Health Organization (WHO) and the International Society of Hypertension risk prediction charts, cardiovascular risk was categorized in a cross-sectional study of 8,625 randomly selected people aged 40-80 years (mean age, 54.6 years) from defined geographic regions of Nigeria, Iran, China, Pakistan, Georgia, Nepal, Cuba, and Sri Lanka. Cost estimates for drug therapy were calculated for three countries.A large fraction (90.0-98.9%) of the study population has a 10-year cardiovascular risk20%. Only 0.2-4.8% are in the high-risk categories (≥ 30%). Adopting a total risk approach and WHO guidelines recommendations would restrict unnecessary drug treatment and reduce the drug costs significantly.Adopting a total cardiovascular risk approach instead of a single risk factor approach reduces health care expenditure by reducing drug costs. Therefore, limited resources can be more efficiently used to target high-risk people who will benefit the most. This strategy needs to be complemented with population-wide measures to shift the cardiovascular risk distribution of the whole population.

Introduction Typhoid fever (TF) continues to cause considerable morbidity and mortality in Nepal, but only limited epidemiologic data is available about TF outside Kathmandu. Methods As part of an interventional trial, we performed a prospective cohort study of bacteremic TF patients in Dhulikhel Hospital between October 2012 and October 2014. Demographic, epidemiological, clinical, and microbiologic data were recorded. Results 116 bacteremic typhoid patients were included in the study. Most were young, healthy, adults (mean age 27.9±12 years), 41.4% of whom were female. More than 70% of patients were employed in non-manual services or were university students. Salmonella Typhi accounted for 64/115 (55.7%) of all isolates, while Salmonella Paratyphi accounted for 51/115 (44.3%), of which 42 were Paratyphi A and 9 Paratyphi B. A significant proportion of TF cases occurred also during the dry season (48/116, 41.6%). The clinical presentation of Salmonella Typhi and Paratyphi infections was similar, except for a greater proportion of arthralgia in patients with Salmonella Typhi. Most Salmonella Typhi and Paratyphi isolates were resistant to nalidixic acid and susceptible to older antibiotics. One Salmonella Paratyphi isolate was resistant to ceftriaxone. Conclusions TF remains common in the Dhulikhel area, even among those with a high level of education. Public health measures aimed at reducing the incidence of TF in the Dhulikhel area are warranted. The relative burden of TF caused by Salmonella Paratyphi is rising; a vaccine with activity against Salmonella Paratyphi is needed. Since Salmonella Paratyphi B was more prevalent in this cohort than in large cohorts of patients from Kathmandu, it is likely that there are significant regional variations in the epidemiology of TF outside Kathmandu.

Background In several languages and settings, the Hospital Anxiety and Depression Scale (HADS) has demonstrated reliable and valid screening properties in psychiatry. Objective To develop a Nepali version of HADS with acceptable reliability and construct validity for use among hospital patients and in the general population. Method The original English version was translated into Nepali using a forward-backward translation protocol. Psychometric properties were tested by factor analysis and Cronbach’s alpha. The translated scale was administered to three groups of adult in-patients in a university hospital in three trials, and to a sample of adults from the community in a fourth trial. Some of the 14 items were reworded reiteratively to achieve viable semantic and statistical solutions. Results The two-factor solution with anxiety and depression subscales eventually explained 40.3% of the total variance. Cronbach’s alpha was 0.76 for anxiety (HADS-A) and 0.68 for depression (HADS-D). All seven HADS-A items showed at least acceptable item-to-factor correlations (range 0.44-0.74), and full construct validity was achieved for this subscale. Item-to-factor correlations for six HADS-D items were also at least acceptable (range 0.42-0.70); one item (D4) had persistently low correlations throughout all trials, although construct validity was still satisfactory. Conclusion Reiterated rewording of items guided by statistical testing resulted in a Nepali version of HADS with satisfactory psychometric properties.

Background Hypertension (HTN), a major risk factor for cardiovascular diseases (CVDs), is a substantial global public health problem. Occasional studies indicate a high prevalence of HTN in the Nepalese population, but no nationwide population-based data exist so far. We opportunistically used a survey of major disorders of the brain in Nepal to measure blood pressure (BP) in participants selected randomly from the adult general population. Objective To establish the prevalence of elevated BP (eBP), and factors associated with it, regardless of any antihypertensive therapy being taken. We took this to be indicative of unmet health-care need. Method This was a cross-sectional study, conducted by unannounced household visits, employing multistage random cluster sampling. To achieve representativeness, 15 districts out of 75 in the country were investigated: one district from each of the three physiographic divisions in each of the five development regions of Nepal. One adult aged 18-65 years was selected from each household and interviewed by structured questionnaire. BP was recorded in a standardised manner by digital device (Microlife 3BM1-3®). Result From 2,109 eligible households, 2,100 adults (99.6%) participated. The prevalence of eBP (>140/90 mmHg on ?2 readings) was found to be 15.1%. Multivariate logistic regression showed significant and independent associations with demographic variables (higher age, male gender), with life-style factors (daily alcohol consumption, BMI ?25), and with living at high altitude (?2000 m). Conclusion In the context of the survey we could not collect data on antihypertensive therapy being taken but, clearly, whatever this might have been, it was failing to meet treatment needs. Almost one in six adults met criteria for hypertension, carrying risk implications for CVDs and their substantial public-health consequences. Two remediable associated factors were identified, although in a cross-sectional survey we could not prove causation. Kathmandu University Medical Journal Vol.13(1) 2015; 3-7

Adherence to iron and folate supplementation during pregnancy is considered key to prevention and control of iron deficiency anemia. Nepal-like other developing countries-faces problems with adherence vis-a-vis iron/folate supplementation.This descriptive survey aimed to assess the effect ofknowledge and perception ofpregnant women on adherence to iron/folate supplementation in Kathmandu, Nepal.The present study was conducted in Paropakar Maternity and Womens' Hospital in Kathmandu. Systematic random sampling was used to select 406 persons who were either given a self-administered questionnaire or interviewed.73.2% of the respondents showed good adherence. Bivariate analysis revealed significant associations between adherence and both knowledge and perception (p0.05), but through multiple linear regression analysis only perception was found to be statistically associated with adherence (p0.05). Further multivariate analysis demonstrated that the most important predictors of adherence were: perception of side effects, availability, forgetfulness and reminders from family.Adherence to iron/folate supplementation among women during pregnancy needs continuous improvement by minimizing the perception of constraints (viz., side-effects and forgetfulness) and, enhancing availability andfamily support.

Background Coronary artery disease (CAD) is associated with the numbers of risk factors causing coronary atherosclerosis. Coronary artery stenosis is mostly caused by coronary atherosclerosis.Objective This study aims to analyze the association between coronary artery stenosis and cardiovascular risk factors.Methods An observational study was conducted among CAD patients. The diagnostic coronary angiogram was performed from femoral approach using standard catheters and techniques to find out any abnormalities.Result A total 73 patients (44 male and 29 female) with coronary artery disease undergoing diagnostic coronary angiography was included with the documented cardiovascular risk factors. The coronary stenosis was found in 40 patients on the basis of stenosis grading. Among the established cardiovascular risk factors, sex, diabetes mellitus and smokers show are significantly associated with coronary stenosis among CAD patients. The present study shows the significant association of coronary stenosis among male CAD patients (OR 2.47; CI 0.94 – 6.48, p

Background Endoscopic Retrograde Cholangiopancreatography (ERCP) is an important but potentially invasive therapeutic procedure in treating various pancreatobiliary conditions. In Nepal, the ERCP services is limited to a few tertiary care centers mostly in the capital, Kathmandu. Dhulikhel hospital has started ERCP since 2011 providing services to patients from all over the country. The study analyzes the outcome from data since August 2011 to 2013 August.Objective To analyze the results of ERCP done in Dhulikhel hospital, Kathmandu University hospital.Method This is a retrospective study. The ERCP records of all the patients done since August 2011 to August 2013 were retrieved. A total of 516 attempts of ERCP were done since August 2011 to August 2013. Out of these, 423 were included for the analysis. The repeat ERCP for the same patient due to failed cannulation or patients undergone ERCP but incomplete documentation were excluded. The demographic data, indications, the findings, the outcome in terms of success or failure to cannulation, success or failure of stone extraction, stenting and complications were all derived and analyzed. SPSS 16 version was employed for data management and analysis.Result The female: male ratio was found to be 1.7 : 1. The mean age of patients were 50.57±17.8 Years. The most common indication for ERCP were: choledocholithiasis 208(49.17%); followed by: obstructive jaundice 69(16.3% ) of undetermined cause, acute biliary pancreatitis 26(6.4%), suspected bile duct injury during cholecystectomy 18(4.2%), periampullary growth 21( 4.96%), Cholangiocarcinoma 12(2.8%), chronic pancreatitis 10( 2.3%), CBD stent exchange 23(5.43%), dilated cbd 21(4.96%) , acute cholangitis 14(3.3%).The most common finding was CBD stone in 308(72.81%), normal in 51(12.1% ), bile duct stricture in 45(10.63%). Bile duct injury during cholecystectomy was found in 13(3.1%), biliary obstruction due to ampullary growth and pancreatic head mass was found in 21(4.96%) and 6(1.41%) respectively. Choledochal cyst was found in 5(1.2%), chronic pancreatitis in 7(1.7%). Biliary fascioliasis was found in one (0.24%); and roundworm in 1(0.24).The most common complication was acute pancreatitis in 17(4%), post-ERCP cholangitis 6(1.4%), bleeding 6(1.4%), duodenal perforation in 1(0.2%), arrhythmia in 1(0.2%) and one death (0.2%).Conclusion ERCP has been a potentially emerging therapeutic tool for various pancreato-biliary disorders in Nepal.Kathmandu University Medical Journal Vol.12(1) 2014: 55-59

Background The major disorders of the brain (MDBs), in terms of their prevalence and the burdens of ill health, disability and financial cost that they impose on individuals and society, are headache, depression and anxiety. No population-based studies have been conducted in Nepal. Aim Our purpose was to assess the prevalence and burden attributable to MDBs in Nepal in order to inform health policy. Here we report the methodology. Methods The unusual sociocultural diversity and extreme geographical variation of the country required adaptation of standard methodology. We ran pre-pilot and pilot studies before embarking on the main study. The study design was cross-sectional. The population of interest were adults aged 18–65 years who were Nepali speaking and living in Nepal. We selected, employed and trained groups of interviewers to visit randomly selected households by cold-calling. Households were selected from 15 representative districts out of 75 in the country through multistage cluster sampling. One participant was selected randomly from each household. We used structured questionnaires (the HARDSHIP questionnaire, Hospital Anxiety and Depression Scale, and Eysenck Personality Questionnaire -Neuroticism), culturally adapted and translated into Nepali. We recorded blood pressure, weight, height and waist circumference, and altitude of each household. We implemented various quality-assurances measures. Results We completed the survey in one month, prior to onset of the monsoon. Among 2,210 selected households, all were contacted, 2,109 were eligible for the study and, from these, 2,100 adults participated. The participation rate was 99.6%. Conclusion Standard methodology was successfully applied in Nepal, with some adaptations. The sociocultural and extraordinary geographic diversity were challenging, but did not require us to compromise the scientific quality of the study.

Background The endocrine changes related to altitude adaptation in human have attracted physiologists around the globe for long. A number of high altitude studies to detect the physiological changes have been performed now and then. But, the study to see the hormonal changes to compare populations residing at different high altitudes is a scarce. Hence, we have performed a study in native populations of different high altitude comparing changes in thyroid hormones in western Nepal. The Jharkot population included in this study is at altitude of 3760m and Jomsom population at 2800m height from sea bed. Objective The study is to compare changes in thyroid hormones at two different high altitude natives. Methods To compare thyroid status between high altitude natives at two different altitudes a cross sectional study is performed by random sampling method. The blood sample was collected in a vacutainer from fifty eight individuals after obtaining the informed consent of participants. The blood collected from antecubital vein was centrifuged in an hour and the serum obtained was used for biochemical analysis of free triiodothyronine, free thyroxine and thyroid stimulating hormone. Results Mean free thyroxine (fT4) of Jharkot population is significantly larger (p = 0.001) than Jomsom population. Mean thyroid stimulating hormone (TSH) with p = 0.597, does not indicate the difference between this two population. There is no significant difference between mean free triiodothyronine (fT3) of Jharkot and Jomsom population (p = 0.345). Conclusion The rise in free thyroid hormone at high altitude is not dependent on the thyroid stimulating hormone released from anterior pituitary. The rise in free thyroxine is found at higher altitude and no difference in fT3 level is detected in population studied at high altitudes.

Background Cardiovascular disease (CVD), is the primary cause of morbidity and mortality in patients with diabetes and have approximately - two to four times higher CVD rate than adult without diabetes. Low density lipoprotein cholesterol (LDL-C) is primarily used as the marker of cardiovascular risk in diabetes despite its several limitations. Although several newer markers of CVD are emerging, no marker has been established in Nepal. Objectives The study was designed to evaluate the non-high-density-lipoprotein- cholesterol(Non-HDL-C) and Total Cholesterol to High density lipoprotein cholesterol (TC:HDL-C ratio) as CVD risk marker in diabetes mellitus. Methods The study was conducted in the Department of Bbiochemistry, Kathmandu University School of Medical Sciences. The study comprised of 76 diabetic subjects and 60 non-diabetic subjects. The anthropometric and biochemical parameters were measured. The Non-HDL-C and TC:HDL-C ratio were also calculated employing their respective formula. Results Body mass index (BMI), waist circumference (WC), blood pressure and lipid parameters were significantly different between diabetic subjects and non-diabetic subjects. There was increased non-HDL-C and TC:HDL-C ratio in subjects with diabetes mellitus. Furthermore, statistically significant correlations of non-HDL-C and TC:HDL-C ratio were obtained with BMI, WC, total cholesterol, HDL-C and LDL-C in diabetic subjects. Conclusions The present study observation revealed that the Non-HDL-C and TC: HDL-C strongly correlate with established independent risk factors such as obesity(WC), elevated blood pressure, HDL-C and LDL-C in diabetes. Thus, the evaluation of Non-HDL-C and TC: HDL-C ratio can be used as the simple, cost-effective and cumulative marker of cardiovascular risk in diabetes mellitus.http://dx.doi.org/10.3126/kumj.v8i4.6239 Kathmandu Univ Med J 2010;8(4):398-404

Objective: The objective of the present study is to evaluate the characteristics of acute poisoning cases admitted to emergency department over a one year period. The demographic, clinical and psycho-social aspects of the patients were analysed. Materials and methods: A hospital based study was carried out in the emergency department, Kathmandu University Teaching Hospital/ Dhulikhel Hospital, Dhulikhel analysing the data of the poisoning cases attended for one year. The study was carried out amongst inpatients attending emergency with acute poisoning. Results: A total of 54 patients were admitted to the emergency department with acute poisoning. The female-to-male ratio was 1.34:1. Most poisoning occurred in the age group of above 40 years. The mean ages of female and male were 29.87 ±14.85 years and 35.54±15.02 years respectively. By occupation 40.38% of the cases were farmers. Only 35.29% of the patients were illiterate. 79.24% of the cases intentionally consume the poison. Organ phosphorus poisoning (OP) was the most common poisoning. Oral route was the commonest route of poisoning accounting 98.1%. Sixty-six percentage (66.66%) of the cases had the poison stored in their home with 27.7% bought from the market once needed. Among the cases of acute poisoning 5.55% were fatal. Conclusion: The following conclusions were reached: (1) females were at greater risk for poisoning than males, (2) self-poisoning cases constituted the majority of all poisonings, and (3) the main agents of self-poisoning were OP poisoning.

The main objective of this study was to determine whether a homemade rapid urease test was reliable when compared to histology in the diagnosis of Helicobacter pylori infection. Endoscopic antral biopsies from 15th August 2004 to 15th July 2005 were studied prospectively. Rapid urease test and histological examination were done on all specimens. Among 160 biopsies, 56 cases showed H. pylori in histological section and 59 cases were rapid urease test positive. Among 56 H. pylori infected patients, the sensitivity, specificity, positive and negative predictive values, percentage of false positive, and percentage of false negative values of rapid urease test were 96.4%, 95.2%, 91.5%, 98.0%, 4.8% and 3.5% respectively. Rapid urease test is positive in significantly higher number (p0.001) in histological positive cases. In conclusion our homemade rapid urease test is a test with good sensitivity and specificity for detection of H. pylori infection.

The complications, therapy and prognosis are significantly determined by the exact location of occlusion site in left anterior descending (LAD) coronary artery in anterior acute myocardial infarction (AMI). This study assessed the role of Electrocardiogram (ECG) as a predictor of coronary artery occlusion site in anterior AMI. Sixty two patients of anterior AMI were divided into two groups according to the occlusion site in relation to first septal and first diagonal branches, proximal--group A and distal--group B. Their initial ECG were analyzed and interpreted. The number of patients having ST elevation in leads aVR and aVL (or = 0.5 mm) were significantly higher in proximal group compared to distal ones (42.3% vs 2.8% and 73.1% vs 22.2%; p0.001). Similarly the number of patients having ST depression in inferior leads, II (or = 1 mm), III (or = 1 mm) and aVF (or = 1 mm) were also significantly higher in proximal group (84.6% vs 22.2%, 88.5% vs 33.3% and 84.6% vs 22.2%; p0.001). The sensitivity of ST depression in inferior leads II (or = 1 mm), III (or = 1 mm) and aVF (or = 1 mm) to predict the proximal lesion were 85.0%, 88.0% and 85.0% respectively, whereas specificity were 78.0%, 67.0% and 78.0% respectively. The ST elevation in a VR had 42.0% sensitivity and 97.0% specificity to predict proximal lesion. Similarly ST elevation in aVL (or = 0.5 mm) had 73% sensitivity and 78% specificity. In anterior AMI, ST elevation in aVR, aVL and ST depression in inferior leads can predict the occlusion site in LAD proximal to first diagonal and first septal branch.

Background: Thyroid hormone has its effect in the lipid metabolism. Thus, thyroid disorder is usually associated with the dyslipidaemia. Hypercholesterolemia is an established risk factor for the cardiovascular disease (CVD) and therefore in case of overt hypothyroidism which is associated with hypercholesterolemia, CVD is most likely to occur. Objectives: controversies still persist about the hypercholesterolemia and sub clinical hypothyroidism. Hence, we conducted our study to elucidate the relation of thyroid hormone with cholesterol in different thyroid disorder. Material and Method: All patients suspected of thyroid disorder within a period of one year were included in the study and free thyroxine-3 (fT3), free thyroxine-4 fT4, Thyroid Stimulating Hormone (TSH) and total cholesterol (TC) in the serum were estimated. Statistical analysis was carried out by using SPSS. 13. Results: Among the 169 cases, 32.5% of the patients were having thyroid disorder. In which 8.3% were of hypothyroid, 7.1% were of sub clinical hypothyroid, 8.3% were of hyperthyroid, 7.7% were of sub clinical hyperthyroid and 1.2% cases were of pan hypothyroid. We observed significant negative correlation between TC & fT3(r = -0.226, p = 0.003), significant negative correlation between total cholesterol & fT4(r = -0.197, p = 0.010) and significant positive correlation between TC & TSH(r = 0.365, p = 0.000). Total cholesterol was significantly raised in hypothyroidism (Mean ±SD 283±53, p = 0.000) in comparison to euthyroid population (mean ±SD, 195±58). But cholesterol was not significantly increased in sub clinical hypothyroidism (mean ±SD, 240±46) Conclusion: Our results show that total cholesterol level in serum is affected by the blood thyroid hormone level. Therefore, screening for hypercholesterolemia could be useful in patients with hypothyroidism to reduce associated disease.

Background: The upper gastrointestinal bleeding (UGIB) is defined as bleeding within the intraluminal gastrointestinal tract from any location between the upper oesophagus to the duodenum at the ligament of Treitz. It is one of the important medical emergencies worldwide. Objective : The objective of this study is to study the aetiology of upper gastrointestinal bleeding based on endoscopic examination findings in patients of various demographic characteristics. Materials and methods: This is a retrospective observational study. The endoscopic record book from 2007 January to 2009 October was reviewed for all the cases who underwent oesophago-gastro-duodenoscopic examination for upper GI bleeding. The clinico-epidemiological data of all the patients was reviewed and analyzed in concert with the aetiology of bleeding. Results: A total of 90 patients (58 males, 32 females; mean age 45.32+ 18.47 years) of upper gastrointestinal bleeding was studied and analyzed in terms of aetiology of bleeding and demographic profile. Among the ethnic groups, Aryan 46 (51%) was the most common ethnic group to have upper GI bleeding followed by Newars 24 (27%), Mongolians 16 (18%), Dalits 3 (3%) and others 1 (1%). Out of 90 patients, 47( 52.2%) cases was less than 45 years of age, 30(33.3%) of 46 to 65 age ; and 13(14.4 %) more than 65 years of age. Gastric ulcer 23(25.6%) was the most common endoscopic finding, followed by oesophageal varices 14 (15.6%), acute erosive/haemorrhagic gastropathy 11 (12.2%), duodenal ulcer 9(10%), growth 7(7.8%), vascular lesions 3(3.3%), Mallory-Weiss tear 1(1.1%), fundal varices 1(1.1%) and, no cause was identified in 21(23.3%) cases. The peptic ulcer bleeding was the most common finding in Aryan 22(47.9%), whereas oesophageal varices and growth were more common in Newar 7(29.2%) and 3 (12.5%) respectively. Conclusion: Peptic ulcer disease is the most common cause of upper GI bleeding which was most commonly found in Aryan population; followed by oesophageal varices and growth as second and third most common causes and were more prevalent in Newar and Mongolian people.

Background Cyanotic congenital heart disease is not a rare entity, but fistula between the right pulmonary artery and the left atrium is an uncommon vascular anomaly. Although it is a real challenge to diagnose the case, detailed clinical evaluation and selective investigations are keys for diagnosis, and surgical intervention is still considered the best treatment option. Case presentation A 19 years old girl from the remote village of Nepal presented with the history of exercise intolerance associated with cyanosis and clubbing of the extremities. We diagnosed her as a case of right pulmonary artery to left atrial fistula, a rare variant of pulmonary arteriovenous malformation. She underwent successful surgical correction of the anomaly under cardiopulmonary bypass surgery. Conclusion Direct communication between the right pulmonary artery and the left atrium is a rare cyanotic congenital heart disease, which is diagnosed late and often associated with the atrial septal defect. The best treatment available is surgical correction.
