Diagnostic role of ovarian – adnexal reporting and data system magnetic resonance imaging scoring system for evaluation of indeterminate adnexal lesions
Introduction: Magnetic resonance imaging (MRI) plays an important role in distinguishing malignant from benign adnexal mass which are indistinguishable from ultrasonography.This can help in early diagnosis and treatment of indeterminate adnexal lesions.This study aims to evaluate the accuracy of ovarian adnexal reporting and data system (O-RADS) MRI score in distinguishing bening from malignant lesion when compared to histopathology which is the gold standard and evaluate MRI features suggesting malignancy in such lesions.
Method: This was a retrospective study of MRI pelvis carried out in patients with indeterminate adnexal lesions who had MRI pelvis done from 2018 to 2022 at Patan Hospital, Lalitpur, Nepal. Ethical approval was obtained from the institutional review committee of Patan Academy of Health Sciences. MRI diagnosis based on O-RADS MRI score was compared with histopathology diagnosis and sensitivity, specificity were calculated. Chi-square test was used and p-value less than 0.05 was considered statistically significant.
Result: Among 175 patients, 135 had benign and 40 had malignant lesions. The sensitivity and specificity of MRI diagnosing indeterminate lesion was 92.5% and 91.85% respectively. Among malignancy, 92.5% had O-RADS MRI score of 4 and 5. Significant statistical association of O-RADS MRI score was found with histopathology diagnosed malignancy. MRI features of malignancy were multilocular, solid cystic lesion with contrast enhancement, septations and diffusion restriction. Malignancy was common in middle aged patients (41-60 y).
Conclusion: O-RADS MRI scoring is significantly associated with histopathology-proven adnexal malignancy and hence helps in accurately diagnosing indeterminate adnexal lesions and stratifying the risk of malignancy
Mapping local patterns of childhood overweight and wasting in low- and middle-income countries between 2000 and 2017
A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall across LMICs between 2000 and 2017, from 8.4% (62.3 (55.1–70.8) million) to 6.4% (58.3 (47.6–70.7) million), but is predicted to remain above the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025. Prevalence of overweight increased from 5.2% (30 (22.8–38.5) million) in 2000 to 6.0% (55.5 (44.8–67.9) million) children aged under 5 years in 2017. Areas most affected by double burden of malnutrition were located in Indonesia, Thailand, southeastern China, Botswana, Cameroon and central Nigeria. Our estimates provide a new perspective to researchers, policy makers and public health agencies in their efforts to address this global childhood syndemic
Accuracy of magnetic resonance cholangiopancreaticography in the diagnosis of benign and malignant cause of obstructive jaundice: Accuracy of MRCP in obstructive jaundice
Introduction: Magnetic Resonance Cholangiopancreatography (MRCP) is non-invasive technique for overall assessment for obstructive jaundice. This study aims to compare accuracy of MRCP in benign and malignant obstructive jaundice with gold standard but the invasive procedure of Endoscopic Retrograde Cholangiopancreatography (ERCP) and histopathology.
Method: This was a retrospective study reviewing MRCP findings of clinically diagnosed obstructive jaundice from 2018 to 2021 at Patan Hospital, Kathmandu, Nepal. Study was conducted after ethical clearance of the institutional review committee. Sensitivity, Specificity, PPV and NPV and overall accuracy of MRCP was compared with the ERCP and histopathology. Chi square test was used for analysis, a p<0.05 considered significant.
Result: Among 66 patients, the Sensitivity, Specificity, PPV and NPV of MRCP for biliary obstruction due to malignant pathology were 89.50%, 93.60%, 85.00% and 95.70% respectively. Similarly, for benign etiology, it was 93.60%, 89.50%, 95.70% and 85.00% respectively. The overall diagnostic accuracy was 92.40%. Choledocholithiasis were 31(46.97%) among benign cause and periampullary carcinoma 8(12.12%) among malignant.
Conclusion: MRCP is highly sensitive and specific test in the evaluation of benign and malignant biliary pathology. Being noninvasive and can have good diagnostic value despite use of contrast. So minimally invasive procedure ERCP can be reserved for therapeutic or diagnostic biopsy purpose only
Extent of Fecal Contamination of Household Drinking Water in Nepal: Further Analysis of Nepal Multiple Indicator Cluster Survey 2014
Drug Act 1978 of Nepal: A Critical Analysis
Background: With the enactment of the Drug Act in 1978, through the establishment of different bodies under the act, drug-related activities have been regulated and controlled in Nepal so as to provide safe and efficacious drugs of standard quality to the general public. However, with the overgrowing use of drugs, cosmetics, biotechnological products, nutraceuticals, and veterinary products in the present market and the present act failing to include these aspects, this paper tries to critically analyze the Drug Act 1978 of Nepal which will comprise strengths, weaknesses, opportunities, and threats faced in current scenario regarding the act. The regulation of drugs in Nepal was started with the enactment of the Drugs Act in 1978 AD, which is being carried out by the Department of Drug Administration as provisioned in the section 5 of the act. To facilitate the proper implementation of the act, various rules, regulations and guidelines are framed. The objective of this study was to explore the areas to improve in the Drugs Act and help foster the use of safe, efficacious and quality drugs.
Method: The Drugs Act 1978 was critically analyzed focusing on the strengths, weaknesses, opportunities, and threats of the act as of current scenario.
Result: After critically analyzing the drugs act 1978 we found out that there is lack in regulations of use of cosmetics, newer biotechnology products, nutraceuticals, veterinary product, innovative pharmaceutical products as well as the online pharmacy services.
Conclusion: A major amendment and periodic revision is required with the consequence of meeting timely needs and promoting the idea of safety and efficacy in drug related activities
Anticoagulation Strategies in Non–Critically Ill Patients with Covid-19
BackgroundOptimal thromboprophylaxis for hospitalized patients with coronavirus disease 2019 (Covid-19) is uncertain.MethodsIn an open-label, adaptive platform trial, we randomly assigned hospitalized adults with Covid-19 to low-dose low-molecular-weight heparin thromboprophylaxis or intermediate-dose or low-dose plus aspirin. In response to external evidence, the aspirin intervention was discontinued and a therapeutic-dose arm added. The primary end point was death or the requirement for new organ support by day 28, analyzed with a Bayesian logistic model. Enrolment was closed as a result of operational constraints.ResultsBetween February 2021 and March 2022, 1574 patients were randomly assigned. Among 1526 participants included in the analysis (India, n=1273; Australia and New Zealand, n=138; and Nepal, n=115), the primary outcome occurred in 35 (5.9%) of 596 in low-dose, 25 (4.2%) of 601 in intermediate-dose, 20 (7.2%) of 279 in low-dose plus aspirin, and 7 (14%) of 50 in therapeutic-dose anticoagulation. Compared with low-dose thromboprophylaxis, the median adjusted odds ratio for the primary outcome for intermediate-dose was 0.74 (95% credible interval [CrI], 0.43 to 1.27; posterior probability of effectiveness [adjusted odds ratioConclusionsIn hospitalized non–critically ill adults with Covid-19, compared with low-dose, there was an 86% posterior probability that intermediate-dose, 65% posterior probability that low-dose plus aspirin, and a 7% posterior probability that therapeutic-dose anticoagulation reduced the odds of death or requirement for organ support. No treatment strategy met prespecified stopping criteria before trial closure, precluding definitive conclusions.

MAPPING LOCAL PATTERNS OF CHILDHOOD OVERWEIGHT AND WASTING IN LOW- AND MIDDLE-INCOME COUNTRIES BETWEEN 2000 AND 2017
A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall across LMICs between 2000 and 2017, from 8.4% (62.3 (55.1–70.8) million) to 6.4% (58.3 (47.6–70.7) million), but is predicted to remain above the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025. Prevalence of overweight increased from 5.2% (30 (22.8–38.5) million) in 2000 to 6.0% (55.5 (44.8–67.9) million) children aged under 5 years in 2017. Areas most affected by double burden of malnutrition were located in Indonesia, Thailand, southeastern China, Botswana, Cameroon and central Nigeria.

Mapping geographical inequalities in oral rehydration therapy coverage in low-income and middle-income countries, 2000–17
Abstract
Background: Oral rehydration solution (ORS) is a form of oral rehydration therapy (ORT) for diarrhoea that has the potential to drastically reduce child mortality; yet, according to UNICEF estimates, less than half of children younger than 5 years with diarrhoea in low-income and middle-income countries (LMICs) received ORS in 2016. A variety of recommended home fluids (RHF) exist as alternative forms of ORT; however, it is unclear whether RHF prevent child mortality. Previous studies have shown considerable variation between countries in ORS and RHF use, but subnational variation is unknown. This study aims to produce high-resolution geospatial estimates of relative and absolute coverage of ORS, RHF, and ORT (use of either ORS or RHF) in LMICs.
Methods: We used a Bayesian geostatistical model including 15 spatial covariates and data from 385 household surveys across 94 LMICs to estimate annual proportions of children younger than 5 years of age with diarrhoea who received ORS or RHF (or both) on continuous continent-wide surfaces in 2000–17, and aggregated results to policy-relevant administrative units. Additionally, we analysed geographical inequality in coverage across administrative units and estimated the number of diarrhoeal deaths averted by increased coverage over the study period. Uncertainty in the mean coverage estimates was calculated by taking 250 draws from the posterior joint distribution of the model and creating uncertainty intervals (UIs) with the 2·5th and 97·5th percentiles of those 250 draws.
Findings: While ORS use among children with diarrhoea increased in some countries from 2000 to 2017, coverage remained below 50% in the majority (62·6%; 12 417 of 19 823) of second administrative-level units and an estimated 6 519 000 children (95% UI 5 254 000–7 733 000) with diarrhoea were not treated with any form of ORT in 2017. Increases in ORS use corresponded with declines in RHF in many locations, resulting in relatively constant overall ORT coverage from 2000 to 2017. Although ORS was uniformly distributed subnationally in some countries, within-country geographical inequalities persisted in others; 11 countries had at least a 50% difference in one of their units compared with the country mean. Increases in ORS use over time were correlated with declines in RHF use and in diarrhoeal mortality in many locations, and an estimated 52 230 diarrhoeal deaths (36 910–68 860) were averted by scaling up of ORS coverage between 2000 and 2017. Finally, we identified key subnational areas in Colombia, Nigeria, and Sudan as examples of where diarrhoeal mortality remains higher than average, while ORS coverage remains lower than average.
Interpretation: To our knowledge, this study is the first to produce and map subnational estimates of ORS, RHF, and ORT coverage and attributable child diarrhoeal deaths across LMICs from 2000 to 2017, allowing for tracking progress over time. Our novel results, combined with detailed subnational estimates of diarrhoeal morbidity and mortality, can support subnational needs assessments aimed at furthering policy makers’ understanding of within-country disparities. Over 50 years after the discovery that led to this simple, cheap, and life-saving therapy, large gains in reducing mortality could still be made by reducing geographical inequalities in ORS coverage
