Comparative analysis of COVID-19 case fatality rate between two waves in Nepal
The first COVID-19 case in Nepal was reported on January 23, 2020. Then infection, then, started to spread gradually, and October marked the most devastating increase in COVID-19 cases of the year 2020. Compared with the October 2020 peak in Nepal, the May 2021 peak of COVID-19 observed 2- and 10-fold rise in new cases and deaths per day, respectively. Given that this surprising increase in the death rate was not observed in other countries, this study analyzed the COVID-19 case fatality rates between the two peaks in Nepal. We found an increase in death rates among younger adults and people without comorbidities
A selective synthesis of taon nanoparticles and their comparative study of photoelectrochemical properties
A simplified ammonolysis method for synthesizing single phase TaON nanoparticles is presented and the resulting photoelectrochemical properties are compared and contrasted with as-synthesized Ta2O5 and Ta3N5. The protocol for partial nitridation of Ta2O5 (synthesis of TaON) offers a straightforward simplification over existing methods. Moreover, the present protocol offers extreme reproducibility and enhanced chemical safety. The morphological characterization of the as-synthesized photocatalysts indicate spherical nanoparticles with sizes 30, 40, and 30 nm Ta2O5, TaON, and Ta3N5 with the absorbance onset at ~320 nm, 580 nm, and 630 nm respectively. The photoactivity of the catalysts has been examined for the degradation of a representative cationic dye methylene blue (MB) using xenon light. Subsequent nitridation of Ta2O5 yields significant increment in the conversion (ζ: Ta2O5 95% ζ for a lower (0.1 g) loading and with a lamp with lower Ultraviolet (UV) content. Improved Photoelectrochemical performance is noted after a series of chronoamperometry (J/t), linear sweep voltammetry (LSV), and electrochemical impedance spectroscopy (EIS) measurements. Finally, stability experiments performed using recovered and treated photocatalyst show no loss of photoactivity, suggesting the photocatalysts can be successfully recycled

Burden of tuberculosis and hepatitis co-infection among people living with HIV in Nepal: a systematic review and meta-analysis
People living with HIV (PLHIV) are prone to tuberculosis (TB) and hepatitis co-infections, which cause substantial burden on morbidity and mortality. However, data on the burden of HIV co-infection from a specific low- and middle-income country are limited. To address this gap in evidence, a meta-analysis of published literature and country surveillance report was conducted to estimate the burden of TB, hepatitis B (HBV) and hepatitis C (HCV) co-infection among PLHIV in Nepal. Twenty-three studies, including 5900 PLHIV, were included in the meta-analysis. The pooled prevalence of HIV-TB, HIV-HBV and HIV-HCV co-infection was 19% (95% CI, 10-28%), 3% (2-5%) and 19% (4-33%), respectively. Low CD4 cell count (pooled odds ratio [OR] 4.38, 95% CI 1.11-17.25), smoking (3.07, 1.48-6.37) and alcohol drinking (3.12, 1.52-6.43) were significantly correlated with HIV-TB co-infection. The odds of HCV co-infection was greater in PLHIV, who were male (5.39, 1.54-18.89) and drug users (166.26, 15.94-1734.44). PLHIV who were on antiretroviral therapy had a reduced risk of HCV co-infection (0.49, 0.36-0.66) than the general PLHIV population. The burden of TB and hepatitis co-infection among PLHIV in Nepal was high. Regular screening of PLHIV for co-infections and prompt initiation of treatment are essential to reduce the transmission of infection and improve quality of life
Community Health Workers Can Identify and Manage Possible Infections in Neonates and Young Infants: MINI\u2014A Model from Nepal
The mortality rates of infants and children aged less than five years
are declining globally and in Nepal but less among neonates. Most
deliveries occur at home without skilled attendants, and most neonates
may not receive appropriate care through the existing medical systems.
So, a community-based pilot programme\u2014 Morang Innovative Neonatal
Intervention (MINI) programme\u2014was implemented in Morang district
of Nepal to see the feasibility of bringing the management of sick
neonates closer to home. The objective of this model was to answer the
question: "Can a team of female community health volunteers and paid
facility-based community health workers (collectively called CHWs)
within the existing heath system correctly follow a set of guidelines
to identify possible severe bacterial infection in neonates and young
infants and successfully deliver their treatment?" In the MINI model,
the CHWs followed an algorithm to classify sick young infants with
possible severe bacterial infection (PSBI). Female Community Health
Volunteers (FCHVS) were trained to visit homes soon after delivery,
record the birth, counsel mothers on essential newborn care, and assess
the newborns for danger-signs. Infants classified as having PSBI,
during this or subsequent contacts, were treated with co-trimoxazole
and referred to facility-based CHWs for seven-day treatment with
injection gentamicin. Additional supervisory support was provided for
quality of care and intensified monitoring. Of 11,457 livebirths
recorded during May 2005-April 2007, 1,526 (13.3%) episodes of PSBI
were identified in young infants. Assessment of signs by the FCHVs
matched that of more highly-trained facility-based CHWs in over 90% of
episodes. Treatment was initiated in 90% of the PSBI episodes; 93%
completed a full course of gentamicin. Case fatality in those who
received treatment with gentamicin was 1.5% [95% confidence interval
(CI) 1.0-2.3] compared to 5.3% (95% CI 2.6-9.7) in episodes that did
not receive any treatment. Within the existing government health
infrastructure, the CHWs can assess and identify possible infections in
neonates and young infants and deliver appropriate treatment with
antibiotics. This will result in improvement in the likelihood of
survival and address one of the main causes of neonatal mortality

Fear, risk perception, and engagement in preventive behaviors for COVID-19 during nationwide lockdown in Nepal
The world has faced huge negative effects from the COVID-19 pandemic between early 2020 and late 2021. Each country has implemented a range of preventive measures to minimize the risk during the COVID-19 pandemic. This study assessed the COVID-19-related fear, risk perception, and preventative behavior during the nationwide lockdown due to COVID-19 in Nepal. In a cross-sectional study, conducted in mid-2021 during the nationwide lockdown in Nepal, a total of 1484 individuals completed measures on fear of COVID-19, COVID-19 risk perception, and preventive behavior. A multiple linear regression analysis was used to identify factors associated with COVID-19 fear. The results revealed significant differences in the fear of COVID-19 in association with the perceived risk of COVID-19 and preventive behaviors. Age, risk perception, preventive behavior, and poor health status were significantly positively related to fear of COVID-19. Perceived risk and preventive behaviors uniquely predicted fear of COVID-19 over and above the effects of socio-demographic variables. Being female and unmarried were the significant factors associated with fear of COVID-19 among study respondents. Higher risk perception, poor health status, and being female were strong factors of increased fear of COVID-19. Targeted interventions are essential to integrate community-level mental health care for COVID-19 resilience
Occluded Coronary Artery among Non-ST Elevation Myocardial Infarction Patients in Department of Cardiology of a Tertiary Care Centre: A Descriptive Cross-sectional Study
Introduction: Non-ST elevation myocardial infarction is frequently thought to be caused by incomplete blockage of the culprit artery, whereas ST elevation myocardial infarction is frequently thought to be caused by total occlusion of the culprit artery. The objective of the study was to find out the prevalence of occluded coronary arteries among non-ST elevation myocardial infarction patients department of cardiology of a tertiary care centre.
Methods: A descriptive cross-sectional study was conducted among non-ST elevation myocardial infarction patients in a tertiary care centre from 22 June 2020 to 21 June 2021 after taking ethical approval from the Institutional Review Committee [Reference number: 4271 (6-11) E2 076/077]. A total of 196 patients were included in the study by simple randomized sampling. Data on the patientâs clinical profile, angiographic findings, and in-hospital complications were recorded. Point estimate and 95% Confidence Interval were calculated.
Results: Among 126 non-ST elevation myocardial infarction patients included in the study, the prevalence of occluded coronary artery was 41 (32.54%) (24.36-40.72, 95% Confidence Interval).
Conclusions: The prevalence of occluded coronary arteries was similar to the studies done in similar settings
Abortion Law awareness and Abortion Services Utilization among reproductive age women of Inarwa municipality of Eastern Nepal
Introduction: Globally, reproductive health and quality of life among female population has been found to be unsatisfactory in developing world. Until 1963, Nepalâs 1854 legal code known as MulukiAin was revised numerous times that banned abortion exempting risk of womenâs life. Enactment of New Abortion Policy from 2003 brought landmark reforms to the womenâs choice in family planning methods and ended the sufferings of lengthy prison sentences for abortion crimes. This study was conducted to explore the level of awareness about abortion law with regard to health care utilization among women of reproductive age group along with its association with socio-demographic characteristics.
Methodology: A cross-sectional study was conducted in March 2014, in Inarwa Municipality among women of reproductive age group (16 to 49 years). Convenient sampling was done to collect data from households. Data was entered and analyzed in SPSS 11.5 and presented in tabular form. Chi-square test was used to show association of awareness of abortion law and socio-demographic variables.
Results: education, age at first marriage and age at 1st pregnancy was found to be significant (p value: <0.005).
Conclusion: As media was the most used source of information, more education on awareness of abortion law and health care utilization should be disseminated through this medium
Global, regional, and national burden of diabetes from 1990 to 2021, with projections of prevalence to 2050: a systematic analysis for the Global Burden of Disease Study 2021

on September 28, 2023BACKGROUND : Diabetes is one of the leading causes of death and disability worldwide, and affects people regardless of country, age group, or sex. Using the most recent evidentiary and analytical framework from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD), we produced location-specific, age-specific, and sex-specific estimates of diabetes prevalence and burden from 1990 to 2021, the proportion of type 1 and type 2 diabetes in 2021, the proportion of the type 2 diabetes burden attributable to selected risk factors, and projections of diabetes prevalence through 2050. METHODS : Estimates of diabetes prevalence and burden were computed in 204 countries and territories, across 25 age groups, for males and females separately and combined; these estimates comprised lost years of healthy life, measured in disability-adjusted life-years (DALYs; defined as the sum of years of life lost [YLLs] and years lived with disability [YLDs]). We used the Cause of Death Ensemble model (CODEm) approach to estimate deaths due to diabetes, incorporating 25 666 location-years of data from vital registration and verbal autopsy reports in separate total (including both type 1 and type 2 diabetes) and type-specific models. Other forms of diabetes, including gestational and monogenic diabetes, were not explicitly modelled. Total and type 1 diabetes prevalence was estimated by use of a Bayesian meta-regression modelling tool, DisMod-MR 2.1, to analyse 1527 location-years of data from the scientific literature, survey microdata, and insurance claims; type 2 diabetes estimates were computed by subtracting type 1 diabetes from total estimates. Mortality and prevalence estimates, along with standard life expectancy and disability weights, were used to calculate YLLs, YLDs, and DALYs. When appropriate, we extrapolated estimates to a hypothetical population with a standardised age structure to allow comparison in populations with different age structures. We used the comparative risk assessment framework to estimate the risk-attributable type 2 diabetes burden for 16 risk factors falling under risk categories including environmental and occupational factors, tobacco use, high alcohol use, high body-mass index (BMI), dietary factors, and low physical activity. Using a regression framework, we forecast type 1 and type 2 diabetes prevalence through 2050 with Socio-demographic Index (SDI) and high BMI as predictors, respectively. FINDINGS : In 2021, there were 529 million (95% uncertainty interval [UI] 500â564) people living with diabetes worldwide, and the global age-standardised total diabetes prevalence was 6·1% (5·8â6·5). At the super-region level, the highest age-standardised rates were observed in north Africa and the Middle East (9·3% [8·7â9·9]) and, at the regional level, in Oceania (12·3% [11·5â13·0]). Nationally, Qatar had the worldâs highest age-specific prevalence of diabetes, at 76·1% (73·1â79·5) in individuals aged 75â79 years. Total diabetes prevalenceâespecially among older adultsâprimarily reflects type 2 diabetes, which in 2021 accounted for 96·0% (95·1â96·8) of diabetes cases and 95·4% (94·9â95·9) of diabetes DALYs worldwide. In 2021, 52·2% (25·5â71·8) of global type 2 diabetes DALYs were attributable to high BMI. The contribution of high BMI to type 2 diabetes DALYs rose by 24·3% (18·5â30·4) worldwide between 1990 and 2021. By 2050, more than 1·31 billion (1·22â1·39) people are projected to have diabetes, with expected age-standardised total diabetes prevalence rates greater than 10% in two super-regions: 16·8% (16·1â17·6) in north Africa and the Middle East and 11·3% (10·8â11·9) in Latin America and Caribbean. By 2050, 89 (43·6%) of 204 countries and territories will have an age-standardised rate greater than 10%. INTERPRETATION : Diabetes remains a substantial public health issue. Type 2 diabetes, which makes up the bulk of diabetes cases, is largely preventable and, in some cases, potentially reversible if identified and managed early in the disease course. However, all evidence indicates that diabetes prevalence is increasing worldwide, primarily due to a rise in obesity caused by multiple factors. Preventing and controlling type 2 diabetes remains an ongoing challenge. It is essential to better understand disparities in risk factor profiles and diabetes burden across populations, to inform strategies to successfully control diabetes risk factors within the context of multiple and complex drivers.Bill & Melinda Gates Foundation.http://www.thelancet.comam2024School of Health Systems and Public Health (SHSPH)SDG-03:Good heatlh and well-bein
Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19
IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19.
Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19.
DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 nonâcritically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022).
INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (nâ=â257), ARB (nâ=â248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; nâ=â10), or no RAS inhibitor (control; nâ=â264) for up to 10 days.
MAIN OUTCOMES AND MEASURES The primary outcome was organ supportâfree days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes.
RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ supportâfree days among critically ill patients was 10 (â1 to 16) in the ACE inhibitor group (nâ=â231), 8 (â1 to 17) in the ARB group (nâ=â217), and 12 (0 to 17) in the control group (nâ=â231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ supportâfree days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively).
CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.
