Abstract
PURPOSE/OBJECTIVE(S) CAR-T cell therapy is limited by toxicity, high cost, logistical manufacturing issues in the autologous setting and risk of GVHD in the allogeneic setting. Substitution of T cells with NK cells opens the possibility for an allogeneic off-the-shelf product with a better safety profile. However, the inadequate efficacy of CAR-NK cells against solid tumors can be extrapolated from experience with CAR-T cells. There is limited but promising preclinical evidence that radiation therapy (RT) enhances CAR-T cell tumoricidal activity against solid tumors. However, there is no data examining the potential synergy between RT and CAR-NK cell therapy. MATERIALS/METHODS We engineered CAR-NK cells with CD27 receptor as extracellular domain to target its natural ligand CD70, which is overexpressed in head-and-neck cancers (HNSCC). CAR-NK cell killing was assessed real-time through xCELLigence cytotoxicity assays. CD70+ OQ01 human HNSCCs were used for most experiments. FaDu is a CD70- HNSCC (negative ctrl). UMRC3 is a CD70+ kidney cancer cell line (positive ctrl). CD70 expression pre- and post-RT was assessed by flow cytometry and Western blot. Ionizing RT was compared at 5 doses: 0, 1.75, 3.5, 7, and 14 Gy. A single dose of 3.5 Gy was used for most experiments. Post-radiation effects were generally assessed at 3 days or 9 days post-RT. Intracellular staining was used to assess NK cell expression of IFN-γ, CD107a, and TNF-α by flow cytometry. CD27/CD70 interaction blockade was through α-CD27 pre-treatment of CAR-NK cells. RESULTS OQ01 HNSCCs heterogeneously express CD70 and are killed by CD70 CAR-NK cells in vitro. Pre-conditioning low-dose RT of 3.5 Gy applied to OQ01 HNSCCs 3 days prior to coculture with NK cells enhances CD70 CAR-NK cell killing, with ∼30% increased cytotoxicity against the tumor cells. Low-dose RT by itself did not induce acute cytolysis. As a possible mechanism for the increased sensitivity of irradiated OQ01 cells to CD70 CAR-NK cells, we found that RT enhances CD70 expression among HNSCCs in a dose-dependent manner. There was no increase in NK cell expression of IFN-γ, CD107a, and TNF-α with exposure to irradiated target cells. CD27/CD70 blockade does not solely abrogate RT-induced sensitization toward CAR-NK cell killing. Despite RT induction of transient increased expression of CD70, which normalizes by 9 days post-RT, there is persistent increase in RT-synergized target cell killing even at this later timepoint. Thus, altogether, RT sensitizes CD70-expressing HNSCC cells to CAR-NK cell killing in vitro. CONCLUSION This work represents the first preclinical study to identify the synergy of RT and CAR-NK cell therapy in solid tumors and is the first demonstration of CAR-NK cell activity against human HNSCCs. We show significantly enhanced potency of CAR-NK cells against irradiated tumor cells in vitro. Collectively, this research will be vital to guide efforts expanding into other target antigens and tumor types.

Abstract
INTRODUCTION Although great strides have been made in maternal and newborn health in Nepal, the maternal mortality ratio (MMR) is still high at 186 per 100,000 births. Many maternal deaths are preventable if there is access to a skilled birth attendant (SBA). The Ministry of Health and Population of Nepal launched the in-service SBA training program in 2007 and has trained over 10,000 SBAs to date. Evidence shows that one episode of training is not enough to retain skills. Therefore, the Nick Simons Institute (NSI) in collaboration with National Health Training Center (NHTC) devised a Follow-Up and Enhancement Program (FEP) in 2011 where the knowledge, clinical skills, and working environment of SBA graduates were assessed directly at their worksites. FEP allows on-site coaching and feedback so that graduates may continue to improve upon any gaps in their knowledge, skills, and working environment. This study aims to assess the effectiveness of FEP. METHODS We used a mixed-methods research design. A total of 73 SBAs who had a pre-FEP assessment in 2016 were followed up for a post-FEP assessment in 2017. We also collected data from 3 additional districts (115 SBAs) that had not previously had FEP, to compare SBAs in FEP versus non-FEP districts. Qualitative data was collected from 16 health facilities on the perceptions, motivation, and satisfaction of stakeholders. RESULTS Of the total 188 SBAs that were sampled, a one-time FEP increased knowledge scores by 9%, clinical skills scores by 29%, and enabling environment scores by 7%. The number of deliveries conducted improved with a one-time FEP, although this increase was not statistically significant. We found a trickle-down effect of working in a facility that has had prior FEP, with SBAs that have never had FEP improving their clinical skills. FEP was found to be a highly accepted program and is beneficial to SBAs, trainers, and the Hospital Management Committee (HFOMC). However, a one-time FEP is not sufficient in retaining clinical skills and knowledge. CONCLUSION FEP is a highly effective program by both quantitative and qualitative evaluation. Our study suggests that FEP should be frequent and continuous to retain the knowledge and clinical skills of SBAs, motivate them through on-site coaching, and improve their working environment through direct feedback to the Ministry of Health and Population.

Abstract
Background Mass vaccination is considered the primary strategy for reducing the impact of COVID-19, and it has been implemented globally. Objective To study the extent of SARS-CoV-2 infection and breakthrough infection among the HCWs who were fully vaccinated for at least 14 days and investigated the relation between neutralizing antibody response and breakthrough infection. Method This study was a retrospective cohort study among health care workers at Dhulikhel Hospital Kathmandu University Hospital from December 2021 to October 2022. The interviews with semi structured questionnaire were conducted in person or over phone. Out of 1450 participants 137 fully vaccinated HCWs without breakthrough infection were randomly selected for the prospective serological cohort. Result Out of 1079 participants' majority (51.8%) were of age 25-34 years. Two thirds (66.7%) were females. More than half of participant (54.7%) had infection with SARS-CoV-2 at least once whereas more than one third people (35%) had reported SARS-CoV-2 infection 14 days after receiving full vaccination. Infection after vaccination had less moderate and sever/critical illness and less need for hospitalization as compared to infection before vaccination. Staffs who were directly involved in patient care had higher chance of breakthrough infection compared to those not involved directly in patient care. Those who had prior infection or booster dose had relatively higher antibody level and participants with low level of antibody had higher chance for breakthrough infection (35.3%) than participants with moderate to high level of antibody (11.9%). Conclusion Vaccinations significantly decreased severe diseases and the need for hospitalizations. Breakthrough infection was higher among the health care workers involved in direct patient care and with low level of antibody.

Abstract
BACKGROUND: TB preventative therapy (TPT) is crucial for reducing the burden of TB in endemic settings. We assessed stigma associated with TPT and the social groups from whom stigma was anticipated.METHODS: We conducted an anonymous cross-sectional survey of community-dwelling adults in rural South Africa. Descriptive statistics, exploratory factor analysis, χ² tests, Kruskal-Wallis tests, and Poisson regression were used to identify factors associated with TPT stigma.RESULTS: The mean age of the 104 participants was 35 years, 65% were female, and 26% had completed secondary school. The vast majority perceived stigma associated with TPT (71%; mean score 1.7, SD ± 1.4). Factor analysis identified a two-factor solution that explained 61.9% of the variance. Being single (P < 0.001), previously screened for TB (P = 0.04), worried about being infected by TB (P = 0.006), and interested in taking TPT (P = 0.01) were associated with higher perceived stigma scores. TPT stigma was perceived among 8%, 16%, and 66% of their family, friends, and other community members, respectively.CONCLUSION: The prevalence of TPT-related stigma in a rural South African community was high. Community members anticipated less stigma from family members compared to other social groups. Global expansion and implementation of TPT will require novel interventions, such as engaging patients´ families to support uptake and promote adherence.

Abstract
Background There is an increasing life expectancy and a surging elderly population in the last few decades, leading to a higher incidence of fractures in the elderly. The health care of the elderly in Nepal is below par and there are no studies done to evaluate the spectrum of fractures in the elderly. Objective To evaluate the demographical and epidemiological aspects of fractures in the elderly (≥ 65 years) presenting to a tertiary care hospital in Nepal in a 15 years' timeline. Method This study was a retrospective epidemiological study conducted in the Department of Orthopedics, Dhulikhel Hospital, Kathmandu University Hospital (DH, KUH), Nepal. The patients of age ≥ 65 years having traumatic injuries, admitted in the orthopedics ward from 2006 January to 2020 December were included. Patient demographics, site of injury, fracture incidence, mechanism of injury, hospital stay duration, and mode of treatment (surgical/ conservative) were evaluated. Result Of the 787 patients with an average age of 73.65 ± 7.5 years, 54% were females. Peritrochanteric fracture was the most common fracture (29.4%) followed by spine (18.3%). The most common mechanism of injury was fall on the labeled ground (38.6%). The incidence of fragility fractures (peri-trochanteric, proximal humerus, spine, and distal radius) was increasing with age. Conclusion Females, peritrochantric fractures, and trivial trauma are the most common occurrences for fractures in elderly. The incidence of fragility fractures is increasing with age but the overall incidence of fractures compared to other studies is low. Higher incidences of road traffic accidents (RTA) and compound fractures among the elderly are serious public health concerns that highlight the importance of primary preventive measures.

Abstract
Background Mucoid degeneration of anterior cruciate ligament is characterized by infiltration of mucoid-like material scattered throughout the anterior cruciate ligament substance. It is an uncommon condition, but previously, underdiagnosed or often misdiagnosed as an anterior cruciate ligament tear. Objective To present our early experiences with mucoid degeneration of anterior cruciate ligament in last five years in terms of clinical presentation and the outcomes of arthroscopic management. Method This was a retrospective descriptive cross-sectional study on patient who received arthroscopic debridement for mucoid degeneration of anterior cruciate ligament in Dhulikhel Hospital over five years period (2017 May to 2022 April). Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scale that has been translated and validated to be used in local (Nepali) language and context was used for evaluation of outcome evaluation. Result Twenty-one patients of mean age 44.21 years, predominantly females (18), were managed in five years period. The mean Western Ontario and McMaster Universities Osteoarthritis Index score was 16.33±10.47 with a range of 0 to 36 (11.57 to 21.09 at 95% confidence interval). The mean Western Ontario and McMaster Universities Osteoarthritis Index score converted on a scale of 0 to 100 was 17. Thirteen patients had isolated Mucoid degeneration of anterior cruciate ligament whereas nine others had associated either meniscal tear or chondral lesions. Conclusion Mucoid degeneration of anterior cruciate ligament could be a cause of knee pain in middle-aged patients and arthroscopic debridement can improve the patient's symptoms and provide a good functional outcome.

Abstract
Abstract
Introduction/Objective
Introduction: Standard diagnostic practices for Urinary Tract Infection (UTI) take 2–3 days for pathogen identification and antibiotic susceptibility testing leading to delayed diagnosis and an increase in healthcare expenditures. The rapid diagnostics tool is highly desirable to identify the pathogen and its antibiotic-resistant genes directly from the samples. Our objective is to validate and evaluate the performance of Open array multiplex PCR for pathogen identification and antibiotic resistance genes.
Methods/Case Report
Method: Open array multiplex PCR method for 20 UTI pathogens was validated using ATCC organisms and inter-laboratory correlation using 50 urine samples. Briefly, samples were homogenized using Omni bead ruptor 96, and DNA was extracted using Hamilton Vantage. Customized open array and UTI chips with 20 most common urinary tract pathogen target and 13 resistant genes target specifically for UTI treatment were filled with Taqman open array PCR master mix and extracted DNA in a 1:1 ratio. UTI chips were prepared on Accufill and real-time PCR was performed on Quantstudio 12K flex. A total of 116 de-identified patient samples were analyzed.
Results (if a Case Study enter NA)
Result: The sensitivity, specificity, and accuracy of this method were more than 90% considering the reference method as the standard method. A total of 14 different types of organisms were detected. Escherichia coli (n=49) was the highest among all. Multiple pathogens were identified in 27 urine samples. Organisms such as Ureaplasma and Megasphaera 1 were detected in nine and four samples, respectively. All positive samples were resistant to at least one or two resistant genes. tetM and tetS were resistant among 72 samples, erm A, B, and C in 60 samples, ESBL in 30 and fosfo A in 21 samples.
Conclusion
Conclusion: The open array multiplex PCR technology may help in the early diagnosis and treatment that can improve patient care, shorten hospitalization, and reduces the economic burden.

Abstract
Abstract
Introduction/Objective
It is estimated that at least 20% of the 5 billion lab orders submitted annually are inappropriate. Use of an appropriate laboratory test utilization management system (TUMS) can significantly overcome this. Laboratory Decision System (LDS) is the only automated TUMS to assist providers understand, select, order, and optimally utilize tests for disease diagnosis and management. This algorithm-based LDS rates and scores potential tests for any given disease and assigns an interpretable numeric score based on clinical relevance, medical necessity, and indication. Importantly, every orders using LDS will also have right CPT and ICD-10 codes assigned to meet the medical necessity and improve reimbursement. Therefore, in this study, we evaluated the performance of LDS as a testing utilization management system and its ability to improve the reimbursement.
Methods/Case Report
A total of 96,170 lab orders were analyzed from a reference laboratory. Of these, 814 tests were accompanied by an invalid ICD10 code and 44,671 tests or were accompanied by ICD10 that are described by Medicare as “never covered” because of inability to meet medical necessity. A total of 160,449 tests were subject to an Medicare policy review from which 112,400 tests met coverage criteria and 48,049 tests did not. These orders were then reevaluated using LDS, which can be accessed from app.medicaldatabase.com/site/api/cpoe or interfaced with EMR to determine if the system would have improved test selection and reimbursement.
Results (if a Case Study enter NA)
Of the original test order sample, 91.5% had an associated LDS score. Of these scored tests, 47.80% met coverage and 43.73% failed to meet coverage, according to the LDS Ranking System. Importantly, LDS provided recommendations for alternative diagnostic ICD10 codes or tests which could have aided physicians in choosing a more appropriate test or submitting a different ICD10 diagnostic code to meet medical necessity. 96.4% with an alternative ICD10 code or test with a score above 5, meeting medical necessity. 80.5% were recommended by the LDS system which would meet Medicare policies.
Conclusion
Use of such algorithm-based testing selection and ordering database that rates and scores potential tests for any given disease based on clinical relevance, medical necessity, and testing indication, would eventually help providers to select and order right test and reduce miss-utilization of tests.

Abstract
Background Primary teeth emergence is an important milestone in children and timing of emergence varies among populations. Objective To determine the emergence time and sequence of primary teeth in a sample of Nepalese children visiting Dhulikhel Hospital. Method A descriptive cross-sectional study was conducted in children of 5 months to 4 years visiting Dhulikhel Hospital. The emergence of incisal tip to incisal margin for incisors and canines, cusp tip to occlusal margin of molars visible were recorded along with age in months and gender. Descriptive statistics was done to calculate the mean age of emergence of each tooth with standard deviation. Unpaired t-test was used to assess the difference between the mean age of emergence of teeth between right and left sides and between boys and girls. Result The first teeth to emerge was mandibular central incisor at the age of 9.37 ± 1.42 months and the last one was maxillary second molar at the age of 32.91 ± 6.39 months. There was no significant difference in the mean emergence time between the maxillary and mandibular jaws, between right and left sides of jaws and between boys and girls except for primary maxillary right central incisor and mandibular right second molar which was found to be emerged early in girls. Conclusion The emergence time and sequence of primary teeth observed in the present study can be used as a baseline data for the children of Kavre district.

Abstract
The superposition of a fundamental laser pulse and its second harmonic can form an asymmetric laser field that is useful in many applications. The temporal characterization of the two-color laser field becomes necessary. However, the temporal characterization of the two-color laser pulse is a challenging task due to its broad bandwidth and a spectral gap between the two frequency components. Here we demonstrate the temporal characterization of the two-color laser field using multiple ionization yield measurements near the laser focus. This new approach enables the complete temporal characterization of the two-color laser field, including the relative phase between the two frequency components.

Abstract
Background Gingivitis simply means the inflammation of gingiva. It is a reversible state but can lead to periodontitis. The final result could be the exfoliation of the tooth causing decreased masticatory function leading to a compromised quality of life. Gingivitis in the pregnant woman should be carefully assessed and treated and given special attention. There is rare documentation on the prevalence of gingivitis in pregnancy in the least developed countries. Objective To evaluate the prevalence of gingivitis in the second trimester of pregnancy and assess its relationship with age, parity, education, occupation, gravidity, oral hygiene habit and frequency of brushing. Method An observational descriptive study was conducted among 384 pregnant females in their second trimester in Kathmandu, Nepal. Demographic variables and general information including those related to oral hygiene practices and habits were collected during an interview. Plaque index and Gingival Index was recorded among the patients through full mouth examination at four sites. Result The prevalence of gingivitis in the second trimester of pregnancy was 76.3%. Statistically significant relationship was found between gingivitis and gravida and parity. A relation could not be established between gingivitis with age, education, occupation, oral hygiene habit and frequency of brushing. Conclusion The prevalence of gingivitis is found to be high in Nepalese pregnant women. Special strategies should be introduced targeting the pregnant women of least developed countries to uplift their periodontal health.

Abstract
Background Medical Products and Technologies is a key component of the health system. Quality medicines and efficient management of the medical products can secure effective cardiovascular diseases management. Objective To collate information and identify strengths, weaknesses, opportunities and threats (SWOT) associated with medical products and technology component for cardiovascular disease management in Nepal. Method This study is a part of a larger rapid assessment of Nepal's health system for cardiovascular disease management and based on The Health System Assessment Approach: A How-To Manual (USAID). The authors conducted a desk review of documents related to the WHO "medical product and technology" building block component and key informant interviews using a pre-tested interview protocol. The first eight interviews were transcribed verbatim and analysed inductively to generate a codebook; and the remaining, transcribed and deductively coded based on the codebook. Findings were categorised into relevant topical area and SWOT components. Result Nepal has laws and provisions for medicine regulation, pharmacovigilance, post marketing surveillance, registration and licensing provisions for pharmacy industries/ outlets, essential medicine lists and national formulary. These provisions also apply to medicines used for cardiovascular diseases. The challenge however, is the lack of effective implementation and monitoring, due to shortages of technical workforce and state of art information and technologies. Information on pharmaceutical expenditures for cardiovascular disease management is scarce; there are no standard national level guidelines that are consistently used to manage cardiovascular diseases in health facilities. Conclusion There are limited provisions and information on medical products for cardiovascular disease management in Nepal, and a need to strengthen existing provisions for medicine regulations and surveillance.

Abstract
Background The important morphological parameters of distal radius namely palmar tilt, radial inclination, radial height and ulnar variance are consequential in the evaluation and management of the distal radius fracture, distal radius plate design and kinesiology. Correction of these parameters in anatomical alignment is important to restore the normal biomechanics of the wrist joint. Objective To ascertain the distal radius parameters in the patients attending tertiary care hospital with regard to gender and age. Method The wrist radiographs (postero-anterior and lateral views) of 125 patients, from 16 to above 60 years of age were used to determine the four parameters of distal radius. The subjects were divided into gender and three different age groups (16-36 years, 37-57 years and > 57 years). Independent t-test and ANOVA test was used for statistical analysis with level of significance set at p ≤ 0.05. Result The mean palmar tilt was 15.69 ± 4.84° (p-value = 0.40). The mean radial inclination was 22.58 ± 2.82° (p-value = 0.88). The mean value of radial height was 10.31 ± 1.59 mm (p-value= 0.001). Positive ulnar variance were recorded in maximum of subjects (46.40%) and the least was neutral (16.80%). Conclusion The distal radius parameters of our population were similar to the Orthopedic Trauma Association standard reference value. And there was significant difference in radial height between males and females.

Abstract
Gallbladder cancer (GBC) is one of the most common and aggressive biliary tract cancers with a dismal prognosis. Ongoing clinical trials are evaluating a few selected immune checkpoint inhibitors (ICIs) as monotherapy for the treatment of GBC patients. However, only a subset of patients benefits from these treatments. To improve ICI therapy response, molecular mechanisms that confer resistance to immune checkpoint (IC) blockade needs to be explored. Epithelial-to-mesenchymal transition (EMT) program and cancer stem cells (CSCs) have been implicated as key processes that confer ICI treatment resistance. However, in GBC the EMT-CSC-IC axis has not yet been clearly elucidated. This study aims to examine the aberrant expression of ICs associated with CSC and EMT. We successfully enriched CSCs by utilizing a 3-dimensional culture system and established a reversible EMT model with human GBC NOZ cell line. Notably, ICs CD73 and PD-L1 were closely associated with both CSC and EMT phenotypes. Knockdown of CD73 or PD-L1 reduced the proliferative and motile abilities of both adherent monolayers and anchorage-free spheroids. In conclusion, blocking CD73 and PD-L1 offer a promising therapeutic strategy for targeting highly aggressive populations with CSC and EMT phenotype to improve GBC patient prognosis.

Abstract
Background Systemic hypertension is one of the most common chronic, debilitating diseases prevalent in the modern era, with many complications in terms of stroke, chronic kidney disease, coronary artery disease and retinopathy. When it comes to the eye, as a target organ damage, it leads to one of the many vision threatening conditions, hence degrading the quality of life. Early detection and subsequent management of patients at risk of hypertensive retinopathy serves to be a crucial panacea in the treatment course. Objective To investigate the characteristics retinal findings among hypertensive population and analyze the associated risk factors. Method A hospital based prospective study was conducted, among 250 patients presenting to ophthalmology outpatient department in Dhulikhel Hospital, Kathmandu University Hospital (DH-KUH), over a time span of 6 months, to analyze hypertensive retinopathy and its implications. Fundus examination under mydriasis was done on all subjects and hypertensive retinopathy was graded according to the modified Scheie classification. Result Most patients belonged to age group of 56-65 years (30%). Nearly half (48%, N=120) of the hypertensive population had some forms of retinopathy. Grade II hypertensive retinopathy (24.8%) was the most common hypertensive change observed. Majority (55%) of the patients with retinopathy were smokers. About two-third of the subjects (67.5%) had been diagnosed to have hypertension and under treatment for over 5 years. Conclusion The occurrence of retinopathy among hypertensive patients attending ophthalmology department is higher. Awareness regarding systemic hypertension and its effect on ocular health is very important to be disseminated among public. Timely referral among medical specialities could diagnose and prevent curable blindness among hypertensive patients.

Abstract
Background The meniscus plays an important role in maintaining healthy articular cartilage. Meniscus tear, one of the common intra-articular knee lesions, is treated by either debridement or repair. Objective This study aims at identifying the early outcome of meniscus tears treated by debridement or repair. This study also elaborates on the spectrum of meniscal injuries presented in a tertiary care hospital in Nepal. Method A retrospective descriptive cross-sectional study was conducted at Orthopedic Department of Dhulikhel Hospital from February 2018 until January 2020 among patients who underwent knee arthroscopies for meniscal tears treated either by debridement or repair. Patients having intra articular fractures, osteochondral injuries and multi-ligament injuries were excluded. The meniscal tears were classified according to location and type of tear. Those patients who had at least one-year of follow up were evaluated with Lysholm score for functional outcome. Data were compiled and analyzed with Microsoft Excel 2011. Result One hundred and ten cases of meniscal tears were managed over the study period. Ninty-three cases could be traced for outcome evaluation, which included 50 cases of meniscal debridement and 43 cases of meniscal repair. The mean Lysholm score of the patients who received debridement was 81.5 (SD 10.4) and those who received meniscal repair was 84.9 (SD 9.1) (p=0.105). The population distribution was found to be similar in both the groups according to age and sex distribution and associated ligamentous injuries. Conclusion Good functional outcome was seen for meniscal tears managed with debridement or repair in at least one year follow up and could not establish one modality of management better than the other.

Abstract
A 34 years old female presented with complains of photophobia since 6-7 months. On examination, she had anisocoria of 4 mm in room light which increased in bright light. The left pupil was dilated and unresponsive to direct and indirect light stimuli. It did however, constrict slowly on near fixation followed by slow redilatation on distance fixation. A diagnosis of Adie's tonic pupil was made since left pupil constricted with instillation of dilute pilocarpine 0.1%. Her symptoms of photophobia and blurred vision immediately resolved. Photochromatic glasses and dilute pilocarpine 0.1% three times a day were prescribed. Prompt symptomatic relief of photophobia and blurred vision was observed.

Abstract
BACKGROUND The number of deaths from drug overdose in the United States has more than doubled in the past decade. In particular, drug overdose deaths involving fentanyl have doubled every year since 2013. Rapid fentanyl test strips (FTS) are a useful strategy for detecting traces of fentanyl in substances and have received overwhelming support from individuals with opioid-dependence. METHODS We investigated fentanyl use, knowledge of FTS, willingness to use FTS, and overdose history among a sample of 105 individuals currently on medication for opioid use disorder (MOUD). RESULTS Results showed that the majority (63%) of the sample had experienced a non-fatal overdose and that 85% of participants were willing to use FTS. The majority of participants reported concern about fentanyl in their drug supply (70%) and 77% reported likelihood of past unintentional fentanyl use. Of note, only about half (47%) of participants knew of FTS prior to being surveyed, and only 17% reported ever using FTS. CONCLUSION These results expand on previous literature that documents high levels of willingness, yet low uptake of FTS among individuals on MOUD. Widespread education about FTS, in addition to the implementation of the use of FTS, is a highly promising and critical primary prevention alternative to overdose treatment and/or death due to fentanyl.

Abstract
Tuberculosis (TB) is the commonest cause of death by a single infectious agent globally and ranks amongst the top ten causes of global mortality. The incidence of TB is highest in Low-Middle Income countries (LMICs). Prompt institution of, and compliance with, therapy are cornerstones for a favourable outcome in TB and to mitigate the risk of multiple drug resistant (MDR)-TB, which is challenging to treat. There is some evidence that adverse drug reactions (ADRs) and hypersensitivity reactions (HSRs) to anti-TB drugs occur in over 60% and 3-4% of patients respectively. Both ADRs and HSRs represent significant barriers to treatment adherence and are recognised risk factors for MDR-TB. HSRs to anti-TB drugs are usually cutaneous and benign, occur within few weeks after commencement of therapy and are likely to be T-cell mediated. Severe and systemic T-cell mediated HSRs and IgE mediated anaphylaxis to anti-TB drugs are relatively rare, but important to recognise and treat promptly. T-cell mediated HSRs are more frequent amongst patients with co-existing HIV infection. Some patients develop multiple sensitisation to anti-TB drugs. Whilst skin tests, patch tests and in vitro diagnostics have been used in the investigation of HSRs to anti-TB drugs, their predictive value is not established, they are onerous, require specialist input of an allergist and are resource-dependent. This is compounded by the global, unmet demand for allergy specialists, particularly in low income countries (LICs) / LMICs and now the challenging circumstances of the SARS-CoV-2 pandemic. This narrative review provides a critical analysis of the limited published evidence on this topic and proposes a cautious and pragmatic approach to optimise and standardise the management of HSRs to anti-TB drugs. This includes clinical risk stratification and a dual strategy involving sequential re-challenge and rapid drug desensitisation. Furthermore, a concerted international effort is needed to generate real-time data on ADRs, HSRs, safety and clinical outcomes of these interventions.

Abstract
SETTING Dhulikhel Hospital, Kathmandu University Hospital, Kathmandu, Nepal. OBJECTIVES 1) To report the incidence of health-care-associated infections (HAIs), 2) to compare demographic, clinical characteristics and hospital outcomes in those with and without HAIs; and 3) to verify bacterial types in HAI and community-acquired infections (CAIs) among inpatients with invasive devices and/or surgical procedures. DESIGN This was a cohort study using secondary data (December 2017 to April 2018). RESULTS Of 1,310 inpatients, 908 (69.3%) had surgical procedures, 125 (9.5%) had invasive devices and 277 (21.1%) both. Sixty-six developed HAIs (incidence = 5/100 patient admissions, 95% CI 3.9-6.3). Individuals with HAIs had a 5.5-fold higher risk of longer hospital stays (⩾7 days) and a 6.9-fold risk of being in intensive care compared to the surgical ward. Unfavourable hospital exit outcomes were higher in those with HAIs (4.5%) than in those without (0.9%, P = 0.02). The most common HAI bacteria (n = 70) were Escherichia coli (44.3%), Enterococcus spp. (22.9%) and Klebsiella spp. (11.4%). Of 98 CAIs with 41 isolates, E. coli (36.6%), Staphylococcus aureus (22.0%) and methicillin-resistant S. aureus (14.6%) were common. CONCLUSION We found relatively low incidence of HAIs, which reflects good infection prevention and control standards. This study serves as a baseline for future monitoring and action.

Abstract
Background Scrub typhus is a largely ignored tropical disease and a leading cause of undifferentiated febrile illness. It is caused by Orientia tsutsugamushi. Scrub Typhus is frequently observed in South Asian countries. However, clear epidemiological information of this disease is lacking in case of Nepal. Nepal has shown steady increase in cases of Scrub Typhus since 2015. The epidemiological data related to this disease would support the decision making and surveillance design for early outbreak detection and immediate responses including prevention and treatment of scrub typhus in Nepal. Objective To understand prevalence of Scrub Typhus in subjects who had visited outpatient department at Dhulikhel Hospital. Method In this study, we have studied antibody test data (n=784) for Scrub Typhus from 2019 to 2021. The tests were performed on serum samples of patients who had visited OPD at Dhulikhel Hospital with fever lasting more than 5 days. The kit used in analysis was Scrub Typhus Detect™ IgM ELISA Kit from InBios International. Result Out of the total subjects (n=784), 133 were positive (16.9%) for IgM antibody of Scrub Typhus. The positivity in female (18.6%) was higher than the male subjects (15.3%). The positivity rate was variable among the different age groups, with highest positivity for age group 0-14 years (25%). The seasonal variation was also observed among the seropositive cases. Conclusion Scrub Typhus being a neglected tropical disease has high prevalence. It can be postulated that female subjects and subjects of age group 0-14 years are vulnerable to the infection with Scrub Typhus. There is need to increase the surveillance of Scrub Typhus to add the knowledge for diagnosis and treatment.

Abstract
Background Influence of timing of injury surgery interval in outcome of osteosynthesis of neck of femur has always been a matter of debate. Patients in our set up have been surgically treated for neck of femur fracture with wide range of injury surgery interval which could have resulted in varied functional outcome and radiological outcome. Objective To evaluate the difference in functional outcome, femoral head osteonecrosis and non-union in fracture neck of femur fixed within and after twenty-four hours. Method All patients, who had undergone osteosynthesis for the neck of femur fractures via open or closed technique from 2010 to 2018 were analyzed retrospectively. The cases were examined and evaluated in terms of injury surgery interval, fracture union, functional status using Modified Harris Hip Score, complications like femoral head osteonecrosis and non-union. Result Fifty patients with an average injury surgery interval of 34±28 hours were evaluated. Twenty three (46%) cases were included in early surgery group (< 24 hours) and 27 (54%) patients were included in delayed (> 24 hours) surgery group. Incidence of femoral head osteonecrosis was reported in two (4%) cases, both being in delayed fixation group (p=0.49). Non-union was reported in four (8%) patients, one in early fixation group and three in delayed fixation group (p=0.61). The average Modified Harris Hip Score in early fixation group was 87 and in delayed fixation group was 84 (p=0.1). Forty two (84%) cases had a good quality of reduction and eight (16%) had a poor reduction. Non-union and functional outcome significantly differed between the good and poor reduction group (p=0.001 and 0.004 respectively). Conclusion There is no significant difference in the functional and radiological outcome of cases operated before and after 24 hours for osteosynthesis of neck of femur fractures in patients 16 to 65 years age group. However, poor reduction is significantly associated with the increased rate of non-union and poor functional outcome.

Abstract
Background COVID-19 is an infectious disease caused by a newly discovered coronavirus. The number of cases and dramatic loss of human life worldwide created psychological problems among general public, including health care workers. Objective To determine the burden of anxiety, depression, and functional impairment among health care workers in the early days of lockdown during the first wave of COVID-19 outbreak in Nepal. Method A hospital-based cross-sectional study was carried out among all the employees of Hospital for Children Eye ENT and Rehabilitation Services, Bhaktapur during the COVID-19 pandemic lockdown from April 3, 2020 to May 2, 2020 using an online questionnaire. The tools used were adopted from Nepali version of Hospital Anxiety and Depression scale (HADS) and Nepali version of WHO Disability Assessment Schedule (WHODAS 2.0). Result The mean age (SD) of the participants (n=86) was 32.53 (7.92) years. Male and female participants were equal in number. The point prevalence of anxiety and depression was 25.6% and 14.0%, respectively. Females had a higher prevalence of both anxiety (39.5% vs 11.6%, p < 0.01) and depression (18.6% vs 9.3%, p=0.351). Clinical and nonclinical staff both had a higher prevalence of both anxiety (31.0% and 20.5%, p=0.265) and depression (16.7% and 11.4%, p=0.478). The mean functional impairment score (WHODAS 2.0) among all participants and participants with anxiety and depression was 19.47 (95% CI: 18.13-20.80), 21.27 (95% CI: 18.08-24.46), and 19.92 (95% CI: 15.28- 24.56), respectively. Conclusion Anxiety and depression during the first lockdown due to COVID-19 pandemic were highly prevalent in clinical and non-clinical employees. Besides controlling the outbreak, special consideration should be given to mental health.

Abstract
Congenital vaginal atresia and cervical agenesis is a rare congenital abnormality of the female genital tract. Here we report a case of 15-year old girl with primary amenorrhea with hematometra, presented with lower abdominal mass. She was symptomatic since 5 months and visited local hospital after 4 months of onset of her symptoms when it became severe, where diagnostic laparotomy was performed for suspected Adnexal mass. Intraoperatively adnexal mass was adhered with and extended up to the uterus with 16 weeks size of uterus. Abdomen was closed without any further intervention and was referred to higher center for needful. When she presented to Kathmandu Model Hospital, she was asymptomatic on her 5th post-operative day of laparotomy. We planned for surgical intervention after examination and investigation. Drainage with vaginoplasty with amnion graft with placement of mould was done.

Abstract
The ACT-America project is a NASA Earth Venture Suborbital-2 mission designed to study the transport and fluxes of greenhouse gases. The open and freely available ACT-America data sets provide airborne in situ measurements of atmospheric carbon dioxide, methane, trace gases, aerosols, clouds, and meteorological properties, airborne remote sensing measurements of aerosol backscatter, atmospheric boundary layer height and columnar content of atmospheric carbon dioxide, tower-based measurements, and modeled atmospheric mole fractions and regional carbon fluxes of greenhouse gases over the Central and Eastern United States. We conducted 121 research flights during five campaigns in four seasons during 2016-2019 over three regions of the US (Mid-Atlantic, Midwest and South) using two NASA research aircraft (B-200 and C-130). We performed three flight patterns (fair weather, frontal crossings, and OCO-2 underflights) and collected more than 1,140 h of airborne measurements via level-leg flights in the atmospheric boundary layer, lower, and upper free troposphere and vertical profiles spanning these altitudes. We also merged various airborne in situ measurements onto a common standard sampling interval, which brings coherence to the data, creates geolocated data products, and makes it much easier for the users to perform holistic analysis of the ACT-America data products. Here, we report on detailed information of data sets collected, the workflow for data sets including storage and processing of the quality controlled and quality assured harmonized observations, and their archival and formatting for users. Finally, we provide some important information on the dissemination of data products including metadata and highlights of applications of ACT-America data sets.

Abstract
Sorafenib, an oral multi-tyrosine kinase inhibitor, has been the first-line therapy for the treatment of patients with advanced HCC, providing a survival benefit of only three months in approximately 30% of patients. Cancer stem cells (CSCs) are a rare tumour subpopulation with self-renewal and differentiation capabilities, and have been implicated in tumour growth, recurrence and drug resistance. The process of epithelial-to-mesenchymal transition (EMT) contributes to the generation and maintenance of the CSC population, resulting in immune evasion and therapy resistance in several cancers, including HCC. The aim of this study is to target the chemoresistant CSC population in HCC by assessing the effectiveness of a combination treatment approach with Sorafenib, an EMT inhibitor and an immune checkpoint inhibitor (ICI). A stem-cell-conditioned serum-free medium was utilised to enrich the CSC population from the human HCC cell lines Hep3B, PLC/PRF/5 and HepG2. The anchorage independent spheres were characterised for CSC features. The human HCC-derived spheres were assessed for EMT status and expression of immune checkpoint molecules. The effect of combination treatment with SB431542, an EMT inhibitor, and siRNA-mediated knockdown of programmed cell death protein ligand-1 (PD-L1) or CD73 along with Sorafenib on human HCC-derived CSCs was examined with cell viability and apoptosis assays. The three-dimensional spheres enriched from human HCC cell lines demonstrated CSC-like features. The human HCC-derived CSCs also exhibited the EMT phenotype along with the upregulation of immune checkpoint molecules. The combined treatment with SB431542 and siRNA-mediated PD-L1 or CD73 knockdown effectively enhanced the cytotoxicity of Sorafenib against the CSC population compared to Sorafenib alone, as evidenced by the reduced size and proliferation of spheres. Furthermore, the combination treatment of Sorafenib with SB431542 and PD-L1 or CD73 siRNA resulted in an increased proportion of an apoptotic population, as evidenced by flow cytometry analysis. In conclusion, the combined targeting of EMT and immune checkpoint molecules with Sorafenib can effectively target the CSC tumour subpopulation.

Abstract
Situs inversus is a congenital condition in which the major visceral organs are reversed from their normal positions, estimated to occur in 1 in 5000-20,000 births. Incidence of gallbladder stone disease is same in these patients and normal patients. Laparoscopic cholecystectomy remains the treatment modality, and performing it successfully in these patients even rarer. We report a 54 years gentleman with gall stone, and 63 years lady who had both gall stone and common bile duct stone along with situs inversus. The mirror image reversibility of the abdominal viscera was seen in both cases. Ports were placed on the opposite side as the liver and the gallbladder were on the left side. Dissection was difficult because being a righthanded surgeon, the non-dominant hand would be the working hand. However, no perioperative complications occurred. It is technically challenging and requires a proper orientation of the left upperquadrant of abdomen.

Abstract
Background The spread of SARS-CoV-2 has become a global public health crisis. Nepal is facing the second wave of COVID-19 pandemic but, there is still a limited data on the genomic sequence of SARS-CoV-2 variants circulating in Nepal. Objective The objective of this study is to sequence the whole genome of SARS-CoV-2 in Nepal to detect possible mutation profiles and phylogenetic lineages of circulating SARSCoV-2 variants. Method In this study, swab samples tested positive for SARS-CoV-2 were investigated. After RNA extraction, the investigation was performed through real-time PCR followed by whole genome sequencing. The consensus genome sequences were, then, analyzed with appropriate bioinformatics tools. Result Sequence analysis of two SARS-CoV-2 genomes from patient without travel history (Patient A1 and A2) were found to be of lineage B.1.1. Similarly, among other four samples from subjects returning from the United Kingdom, genomes of two samples were of lineage B.1.36, and the other two were of lineage B.1.1.7 (Alpha Variant). The mutations in the consensus genomes contained the defining mutations of the respective lineages of SARS-CoV-2. Conclusion We confirmed two genomic sequences of variant of concern VOC-202012/01 in Nepal. Our study provides the concise genomic evidence for spread of different lineages of SARS-CoV-2 - B.1.1, B.1.36 and B.1.1.7 of SARS-CoV-2 in Nepal.

Abstract
Background Osteoarthritis (OA) is the most common chronic rheumatic disease. The prevalence of OA is skyrocketing with time. Providing a proper treatment regimen for OA is also growing as a major public health challenge. Conventional pharmacological treatments are mainly for alleviating pain and have some severe adverse effects. Diacerein is a new oral anti-inflammatory drug especially developed for the management of OA having only mild to moderate adverse effects. However, the evidence of efficacy and safety of Diacerein in OA is not well documented and yet to be explored. Objective To compare the efficacy and safety of Diacerein in knee OA with conventional nonsteroidal anti-inflammatory drugs (NSAIDs). Method A comparative study was conducted among knee OA patients attending OutPatient Orthopedic department in Dhulikhel Hospital, Nepal from December 2019 to September 2020, using self-structured and standard questionnaire. The patients were randomized to receive either a conventional standard treatment (Treatment Group I: NSAIDs) or alternative treatment regimen (Treatment Group II: NSAIDS+ Diacerein). Patients were followed-up after two months and data were analyzed using SPSS 21.0. Result Among 72 patients enrolled in this study, majority (44.44%) were between 51-60 years of age in which 81.94% of the patients were female. Post treatment data was collected from 15 participants. The mean KOOS-PS score of the participants in Treatment Group I decreased from 35.56 ± 14.33 to 35.14 ± 12.65 while that of the Treatment Group II participants reduced from 63.31 ± 12.08 to 49.99 ± 13.10 in two months. Similarly, the mean WOMAC score decreased from 46.87 ± 17.80 to 34.37 ± 16.83 in Treatment Group I and from 54.23 ± 14.66 to 46.22 ± 12.16 in Treatment Group II. The mean Lysholm score in Treatment Group I increased from 55.57 ± 8.16 to 60.86 ± 15.01 and in Treatment Group II, it increased from 46.62 ± 13.01 to 60.25 ± 17.598. Conclusion Diacerein treatment group had better functional outcome compared to the patients in the treatment group with conventionally used drugs. Also, the adverse effects faced by the patients were minor. The current study are suggestive of better efficacy and safety of Diacerein compared to other drugs.

Abstract
The first case of coronavirus disease 2019 was reported on December 31, 2019 in Wuhan, China where the average case fatality rate was 6.1 ± 2.9%. There are 453 deaths as of September 24, 2020 in Nepal. We report the first death of a 29-years-old postpartum woman due to COVID-19 in Nepal who was referred from a rural health center to Dhulikhel Hospital. On arrival, she was taken to the acute respiratory zone of the emergency department to provide immediate lifesaving procedures. Despite the repeated resuscitative measures, return of spontaneous circulation could not be achieved. The real time polymerase chain reaction test was positive. Our case report highlights the importance of early clinical suspicion, importance of "safety first" in healthcare settings, and the chain of management in such patients. We consider the fact that a postpartum woman registered as the first case of COVID-19 related death in Nepal to be an area of further study.

Abstract
Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer with a high mortality rate. Epithelial-to-mesenchymal transition (EMT) confers cancer cells with immune evasive ability by modulating the expression of immune checkpoints in many cancers. Thus, the aim of our study is to examine the interplay between EMT and immune checkpoint molecules in HCC. A reversible EMT model was utilised with transforming growth factor (TGF)-β1 as an EMT inducer for HCC cell lines Hep3B and PLC/PRF/5. HCC cells were treated with TGF-β1 for 72 h and the EMT status and immune checkpoint expression were examined. In addition, the migratory ability of HCC cells were examined using wound healing and transwell migration assays in the reversible EMT model. siRNA-mediated knockdown of immune checkpoint molecule, B7-H3, was further utilised to validate the association between TGF-β1-mediated EMT and immune checkpoint expression in HCC. In addition, a web-based platform, SurvExpress, was utilised to evaluate the association between expression of TGF-β1 in combination with immune checkpoint molecules and overall survival in HCC patients. We observed induction of EMT upon treatment of HCC cells with TGF-β1 revealed by reduced expression of epithelial markers along with increased expression of mesenchymal markers. Withdrawal of TGF-β1 reversed the process of EMT with elevated expression of epithelial markers and reduced expression of mesenchymal markers. TGF-β1 treatment elevated the migratory potential of HCC cells which was reversed following reversal assay. Notably, during TGF-β1-induced EMT, there was upregulation of immune checkpoint molecules PD-L1 and B7-H3. However, the reversal of EMT decreased the expression of PD-L1 and B7-H3. In addition, TGF-β1 driven EMT was reversed following knockdown of B7-H3 in both HCC cells further validating the interplay between TGF-β1-mediated EMT and immune checkpoint expression in HCC. Furthermore, the coordinate expression of TGF-β1 with PD-L1 (p=0.01487) and B7-H3 (p=0.009687) was correlated with poor overall survival in 422 HCC patients. Our study has demonstrated a close association between TGF-β1-mediated EMT and regulation of immune checkpoints in HCC.

Abstract
Antibiotic resistance is one of the world's greatest public health challenges and adjunct probiotic therapies are strategies that could lessen this burden. Clostridioides difficile infection (CDI) is a prime example where adjunct probiotic therapies could decrease disease incidence through prevention. Human-derived Lactobacillus reuteri is a probiotic that produces the antimicrobial compound reuterin known to prevent C. difficile colonization of antibiotic-treated fecal microbial communities. However, the mechanism of inhibition is unclear. We show that reuterin inhibits C. difficile outgrowth from spores and vegetative cell growth, however, no effect on C. difficile germination or sporulation was observed. Consistent with published studies, we found that exposure to reuterin stimulated reactive oxygen species (ROS) in C. difficile, resulting in a concentration-dependent reduction in cell viability that was rescued by the antioxidant glutathione. Sublethal concentrations of reuterin enhanced the susceptibility of vegetative C. difficile to vancomycin and metronidazole treatment and reduced toxin synthesis by C. difficile. We also demonstrate that reuterin is protective against C. difficile toxin-mediated cellular damage in the human intestinal enteroid model. Overall, our results indicate that ROS are essential mediators of reuterin activity and show that reuterin production by L. reuteri is compatible as a therapeutic in a clinically relevant model.

Abstract
Objective To investigate the effects of different molecular weight (MW), wool derived hydrolysed keratins (i.e. peptides) on the physical properties of relaxed textured hair. Methods Very curly hair of African origin was relaxed using sodium hydroxide‐based treatment. Relaxed hair was treated with different MW peptides derived from keratin protein and an amino acid, L‐Leucine. The low‐MW keratin peptides were 221 Da, the mid‐MW keratin peptides were approximately 2577 Da, and the high‐MW keratin peptides were approximately 75 440 Da. The penetration of these different peptides into relaxed hair was evaluated using a laser scanning micrometre and by fluorescence microscopy. The effect of these compounds on single‐fibre mechanical properties and thermal properties was evaluated using tensile and DSC testing, respectively. Results Low‐ and mid‐MW compounds were able to penetrate deep into the hair cortex. High‐MW peptide adsorbed onto the hair surface and possibly slightly penetrated into the outer layers of the fibre surface. Both mid‐ and high‐MW keratin peptides, increased Young’s modulus and reduced hair breakage at 20% and 80% relative humidity. With the exception of mid‐MW peptide, other peptides and amino acid were not able to modify thermal properties of relaxed textured hair. Conclusions Our data suggest that low‐MW compounds may increase hair volume, and high‐MW peptides may repair damage on freshly relaxed textured hair.

Abstract
Dysgerminomas account for approximately one third of all malignant ovarian germ cell tumors (tumors arising from ovarian germinal elements) and are the most common ovarian malignancy detected during pregnancy. They are the only germ cell malignancy with a significant rate of bilateral ovarian involvement that is 15-20 percent. They have a variable gross appearance, but in general are solid, pink to tan to cream colored lobulated masses. They have the best prognosis of all malignant ovarian germ cell tumor variants. Two thirds are stage I at diagnosis, and prognosis is excellent even for those with advanced disease due to exquisite tumor chemosensitivity. The 5 year disease specific survival rate approximates 99 percent. This is a case report of a huge ovarian dysgerminoma in a young unmarried lady that was quite asymptomatic. She underwent laparotomy with right ovarian cystectomy.

Abstract
Background The global health community has emphasized the importance of reporting epidemiological data by age and sex groups in the COVID-19 pandemic. However, age and sex disaggregated data of COVID-19 cases and deaths are rarely reported. Such data are very crucial for public to make truly informed choices about their own diseases risk and also for governments for public policy response. Objective To assess age and gender difference among COVID-19 cases and deaths in Nepal. Method This is a retrospective study which uses public data on COVID-19 cases and deaths released by Ministry of Health and Population, Government of Nepal from January to November, 2020. The data analysis was carried out using SPPS software version 26. Result Nepal reported 233,452 confirmed cases and 1,566 deaths of COVID-19 from 23 January 2020 to 30 November 2020. We found statistically significant differences on COVID-19 cases by age and gender in Nepal with higher number of cases among males of economically active age groups (20-60 years). Similarly, we found significant difference in COVID-19 mortality with more death occurred among male group compared to female group and with highest number of deaths among the people of above 60 years. Furthermore, we found differences in cases and deaths among provinces. Conclusion The age and gender differences in COVID cases and deaths in Nepal indicates needs of considering age and sex groups seriously while planning for testing, case management and vaccination against COVID-19 infections in Nepal.

Abstract
Background Hormonal contraceptives are one of the most commonly used means of contraception. Lack of contraception may lead to large family size, increased preexisting illness on pregnancy, social and economic instability, risk of unsafe abortion and so on. This may also lead to unintended pregnancies which may alter the outcomes of pregnancies as well. However, improper uses are associated with several serious adverse effects. Therefore, to achieve the optimum benefit with the least adverse effects, safe and effective use of these agents with monitoring of their pattern of use and patient compliance is very essential. Objective To investigate the usage of hormonal contraceptives and the adverse effects associated with them. Method A cross-sectional study was conducted in a family planning center of a tertiary care hospital. All women of reproductive age using hormonal contraceptives for at least 1 month were included in this study. Informed consent was taken from the patients and interviewed using a structured questionnaire. Statistical analysis was performed by using SPSS 20. Result Among the 105 participants under this study, the mean (±SD) age was 29.08 (± 6.12) years. A majority (42, 40.0%) of them were using injectables. The average duration of use of hormonal contraceptives was 25.1 months ± 31.8 while a majority (60, 57.1%) were using contraceptives from < 3 months. Less chance of missed dose was the major reason (26.8%) for choosing injectable. Adverse effects were reported by 75.2% of the patients. The most common adverse effect was menstrual abnormalities (21.7%). Conclusion Among various hormonal contraceptives, injectables were more commonly used. The majority of the participants responded to use injectables because of the least chance of missing the dose. The most common adverse effect reported was menstrual abnormalities.

Abstract
Background Antimicrobials agents are the most widely and often imprudently used therapeutic drugs globally. The pediatric population comprises 20-25% of the total world population, and various acute and chronic diseases are prone to this group. It is also estimated that 50% to 85% of children are prescribed with antimicrobials in developed and developing countries. The misuse of antimicrobials not only contributes not only to the development of antimicrobial resistance but also results in economic burden on the health care system. Objective To analyze the antimicrobial usage and its cost analysis in the Pediatric department of a tertiary care hospital at sub-urban area. Method A hospital based retrospective study was conducted among patient (aged 1 to 18 years) admitted in pediatric ward and intensive care unit for at least 24 hours and dispensed at least one antimicrobial drug from January 2018 to December 2019. Data were collected from electronic medical record using a structured data collection form. The data was entered and analyzed using Microsoft Excel. A descriptive analysis was presented as mean ± (standard deviation) for the continuous variables and frequencies and proportions for categorical variables. Result Among the 1,281 patients, the antimicrobials were prescribed mostly in the respiratory tract infection (39.6%), followed by sepsis (19.75%), enteric fever (11.94%), seizure (10.07%), urinary tract infection (4.29%). Penicillins (1238 times) were highly prescribed followed by Cephalosporin (733 times), Nitro-imidazole (292 times), Aminoglycosides (180 times) and Fluoroquinolones (144 times). During study period in the Pediatric Department, approximately NRs. 1,619,121.11 was spent in the antimicrobial drugs and the highest expenditure was found to be in the Cephalosporin group of antimicrobials (NRs. 530,988.6), followed by Penicillin group of drug (NRs. 3,81,842.2). Conclusion The study concludes that the Penicillin groups of drugs were the most commonly prescribed drug and the highest cost was found to be in Cephalosporin group drugs followed by Penicillin group of drugs.

Abstract
Background Cardiopulmonary resuscitation is the foundational technique for the emergency treatment of cardiac arrest and the standardized training of it has been emphasized more than ever. Competence of the nurses in this lifesaving procedure is a critical factor in patient outcome from cardiac arrest and can largely prevent sudden death. Objective Many evidences suggest lack of knowledge on proper cardiopulmonary resuscitation among nurses so the aim of this study was to assess the knowledge on 2015 American Heart Association guidelines update for cardiopulmonary resuscitation among nurses working at University hospital and to identify the relationship between the level of knowledge and selected variables. Method Two hundred and sixty nurses working in Dhulikhel hospital participated in the study. A cross-sectional descriptive study was conducted using a predesigned questionnaire based on 2015 guidelines updates for cardiopulmonary resuscitation that incorporated total of 20 questions. Result Total 260 participated in the study and all were female. Only one third of the nurses had good knowledge regarding 2015 guidelines update for cardiopulmonary resuscitation. No significant results existed between the knowledge score and age of the nurses, duration of work experience. However, significant results existed between the knowledge score and qualification, designation of the nurses and previous training on cardiopulmonary resuscitation. Conclusion One third of the nurses had good knowledge regarding 2015 guidelines update for cardiopulmonary resuscitation in this study. Thus, knowledge and practical approach has to be updated with current guidelines in cardiopulmonary resuscitation in order to improve the safety and effectiveness of patient care.

Abstract
Background Pregnancy or gestation is the time during which a single or more children grows and develops inside a woman. Antenatal care improves the pregnancy outcomes under which a group of medication i.e. iron, folic acid and calcium are supplemented. Despite the effectiveness of such supplements, poor clinical outcomes are often encountered because of poor-adherence to the regimen. Objective To determine the adherence pattern and factors affecting adherence in antenatal care patients under iron, folic acid, and calcium therapy. Method A cross-sectional study was conducted in Dhulikhel Hospital, Kathmandu University Hospital. Pregnant women attending antenatal care under iron, folic acid, and calcium therapy fulfilling the inclusion criteria were enrolled in this study. After obtaining the informed consent from the patients, structured questionnaire was used to interview the patients. Statistical analysis was performed by using SPSS 23.0. P-value < 0.05 was considered as statistically significant. Result Among 191 patients enrolled in this study majority (39.3%) of them belonged to age group 26-30 years. More than half (61.3%) of the patients were illiterate. Of the total 191, 64.40% were non-adherent to the medication. Forgetfulness was the main reason for missing the dose in majority (52.06%) of the non-adherent subjects while adverse effects (55.40%) was the most prominent cause for discontinuing the medication among non-adherent participants. Significant association was found between patients' adherence and busy work schedule, visiting doctor for follow up. Conclusion More than half of the patients had not adhered to the medication under antenatal care. Forgetfulness was the most common factor for missing the dose in nonadherent patients. Illiteracy was associated with poor adherence. Patient-provider relationship, Socio-economic factors were determined as major barrier to medication adherence.

Abstract
Background Ingested foreign body impaction on upper gastrointestinal tract is common incidence among children, older age group, mentally challenged individuals, and people the influence of alcohol. In most cases, the foreign bodies pass spontaneously and uneventfully but when this does not occur; endoscopic management to ensure removal under direct visualization is required. Relief upon removal of foreign body and prevention of complications is essential. Objective To assess the endoscopic management and outcome of foreign body impacted in the upper gastrointestinal tract. Method This is a hospital based observational retrospective cross sectional study involving 165 patients at Endoscopy Department of Dhulikhel Hospital in Nepal between November 2015 and October 2019. The data regarding the demographic profile, clinical characteristics and endoscopic findings were retrieved and analyzed to determine endoscopic interventions performed, complications and outcomes. Result One hundred and sixty five patients presenting with history of ingestion of foreign body were included in the study. The mean age of the patients was 46.8 ± 19.1 years with male predominance (60%). The most common site of foreign body impaction was oesophagus (70%). The most common foreign body encountered was bone (62.2%) among which chicken bones (91.1%) were most frequent. For the retrieval of sharp-pointed foreign bodies, rat forceps and graspers (45.7%) were most commonly used. Total 14 cases required rigid oesophagoscopy as the foreign body could not be retrieved by flexible endoscopy. Conclusion Foreign body ingestion and its impaction in the upper gastrointestinal tract has been found to be common in endoscopic practise. Early detection and timely removal of foreign bodies is of utmost importance to avoid discomfort to the patient as well as to ensure successful removal without complications.

Abstract
Hepatocellular carcinoma (HCC) is the fastest growing cause of cancer-related deaths globally. Epithelial-to-mesenchymal transition (EMT) is a cellular process that confers HCC tumor cells with the ability to evade the immune system. Immune escape in most tumors, including HCC, is controlled by immune checkpoint molecules. The aim of the present study was to investigate the association between EMT and immune checkpoint in HCC, and identify novel therapeutic targets for HCC. An in vitro model of reversible EMT was utilized based on cytokine tumor necrosis factor (TNF)-α treatment of HCC cell lines Hep3B and PLC/PRF/5. Hep3B and PLC/PRF/5 cells were treated with TNF-α, and the EMT status and the expression of immune checkpoint molecules was assessed by reverse transcription-quantitative PCR, western blotting and immunofluorescence. To confirm an association between EMT and immune modulators, cells were exposed to culture medium with TNF-α for 3 days to induce EMT, following which a reversal assay was performed. The expression of immune modulators and mesenchymal-to-epithelial transition (MET) status was investigated upon reversal of EMT. Furthermore, SurvExpress, a web-based platform was utilized to analyze survival and recurrence in a dataset of patients with HCC. TNF-α treatment for 3 days induced EMT in Hep3B and PLC/PRF/5 cells, as demonstrated by the downregulation of epithelial markers along with upregulation in mesenchymal markers. An EMT reversal assay was able to induce MET by increasing epithelial markers and decreasing mesenchymal markers. TNF-α-induced EMT led to the upregulation of immune modulators, including programmed death receptor ligand (PD-L)1, PD-L2, CD73 and B7-H3. In contrast, reversal of EMT suppressed the expression of PD-L1, PD-L2, CD73 and B7-H3. In addition, high expression of TNF-α and PD-L1 in 422 patients with HCC was associated with poor overall survival. The coordinate expression of TNF-α with PD-L2 in this patient cohort was associated with increased HCC recurrence. In conclusion, the present study demonstrated a close association between immune modulator expression and EMT induction/reversal driven by TNF-α.

Abstract
Background Helicobacter pylori is one of the most prevalent infectious disease worldwide. The treatment regimens involve mainly two therapies: Standard Triple drug therapy and Sequential drug therapy. Several studies have shown that the sequential therapy has higher eradication rates of H. pylori than the standard triple drug therapy and since proper study on sequential drug therapy and standard triple drug therapy is still lacking in Nepal, this study is attempted to compare efficacy of Sequential Drug Therapy in the eradication of H. pylori in gastritis with respect to the Standard triple drug therapy. Objective To investigate the efficacy of Triple Drug Therapy and Sequential Drug Therapy in the eradication of Helicobacter pylori with respect to Antigen Stool test. Method This study was the prospective study conducted in 62 patients attending the Department of Gastroenterology, Dhulikhel Hospital, meeting the inclusion criteria who were confirmed as H. pylori positive by histopathology and stool antigen test. Patients were randomized into two groups. One group prescribed with Standard triple drug regimen and another group with Sequential drug regimen. Eradication of H. pylori infection was confirmed by repeating the stool antigen test at least five weeks after the completion of the regimen. Result Among the 62 participants included in this study, 54.5% of them were males. Among the study population, the eradication achieved by standard triple drug therapy was 87.8% and 89.6% with Sequential drug therapy. Higher numbers (82.3%) of patients were compliant to the prescribed medication. Forgetfulness was the main reason for missing the dose (91%) of the non-compliant patients. Conclusion The study revealed an equal efficacy of both Standard Triple drug regimen and Sequential drug regimen in the eradication of H. pylori infection. Further, Stool antigen test can be preferred as a non-invasive test, for diagnosis of H. pylori infection, monitoring the response to treatment and in epidemiological studies.

Abstract
Background Antimicrobial resistance (AMR) and healthcare-associated infections (HAIs) are among the most serious public health problems and overall estimate indicates that at any point, over 1.4 million people are suffering from health care associated infection globally. According to the WHO report, the frequency of nosocomial infection is 10% in South East Asia where as 7% in developed countries. The increasing trend of AMR in pathogenic bacteria leads to complication to treat HAIs and failure in treatment and rise in mortality. Objective The study was conducted with the objective of to explore the incidence of different types of HAIs and AMR pattern in the patients admitted in a tertiary care hospital. Method The cross-sectional study was conducted at the tertiary care hospital and the patient who are one year or older and admitted for more than 48 hours were included in this study. The criteria for classification of HAIs were adapted from Centers for Disease Control. All the samples were collected then antibiotic sensitivity testing was conducted according to CLSI standards. Data were collected using a structured data collection form. Data were entered in EpiData software and analyzed using SPSS version 22. Result Among 2326 patients, female was slightly higher than male patients, where 77 (3.3%) patients experienced at least one episode of HAIs. The surgical site infection (71.42%) is the most common infection followed by Catheter Associated Urinary Tract Infection (18.18%) and Health Care Associated Pneumonia (6.49%). Mean hospitalization days is higher with HAI (14.5 days) compared to non-HAI (6.6 days). Out of 909 specimens, urine, sputum and blood were higher in numbers, where 217 bacterial isolates were isolated with Escherichia coli (83 isolates) was the most common bacteria. It is found that Escherichia coli bacterial isolates were resistance to most common antibiotics. Conclusion The study concludes that surgical site infection is the most common healthcareassociated infection and Escherichia coli is the most common bacteria responsible for HAIs. Further, surgical site infection being the most common infection, there is an urgent need to take effective infection prevention and control prevention.

Abstract
Background Diabetes is a chronic disease that occurs either when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin it produces. Though oral hypoglycemic agents (OHAs) or/and insulin are prescribed to control the hyperglycemia, still glycemic control is not seen in most of the cases. Evaluating the treatment pattern including the glycemic control and associated factors are of utmost importance for better patient care. Objective To investigate the treatment pattern and short term glycemic control among Type 2 Diabetes Mellitus (DM2) patients and study the factors associated with it. Method Patients meeting the inclusion criteria with DM2 attending laboratory or Out-Patient Department or Emergency Department in Dhulikhel Hospital and patients who were admitted to the ward taking various OHAs and/or insulin at the time of data collection were considered. Informed consent was taken prior to the interview. The collected data was entered as well as analyzed using the SPSS (Statistical Package for Social Sciences) version 21.0 and the p-value <0.05 was considered statistically significant. Result Among the 118 patients, 50.8% of them were males. Majority (28%) of the patients belonged to the age group of 51-60 years. Out of the 118 patients, 22% had their fasting blood glucose (FBG) level under control whereas 78% had uncontrolled FBG level. Metformin was the most (28%) commonly prescribed drug. Significant association was found between gender; knowledge about disease and medication with short term glycemic control (p=0.034, p=0.004 ans p=0.039 respectively). Conclusion All the patients enrolled in this study were under various anti-diabetic medications, however, majority of them didn't have their glycemia under control. Significant association was found between FBG level and gender, knowledge about disease and knowledge about medication.
