    Previously we have shown that avian leukosis virus subgroup J (ALV-J) might be present in chicken flocks from Malaysia based on serological study and also on detection of tissue samples with myelocytic infiltration. In this study, the polymerase chain reaction was used to detect ALV-J sequences from archived frozen samples. Out of 21 tissue samples examined, 16 samples were positive for proviral DNA and four samples for ALV-J RNA. However, only nine samples were found positive for myelocytic infiltration. A total of 465 base pairs equivalent to positions 5305 to 5769 of HPRS-103 from each of the viral RNA positive samples were characterized. Sequence analysis indicated that the samples showed high identity (95.9 to 98.2%) and were close to HPRS-103 with identities between 97.4 and 99.3%. This study indicates that ALV-J-specific sequences can be detected by polymerase chain reaction from frozen tissue samples with and without myelocytic infiltration.

    INTRODUCTION: Antimicrobial resistance is a global health problem. The widespread and improper antibiotics use is the leading cause of antimicrobial resistance. Bacterial co-infection in COVID-19 patients is the basis for the use of antibiotics in the management of COVID-19. COVID-19 pandemic has seriously impacted antibiotic stewardship and increased the global usage of antibiotics, worsening the antimicrobial resistance problem. The use of antibiotics among COVID-19 patients is high but there are limited studies in the context of Nepal. This study aimed to find out the prevalence of antibiotic use among hospitalised COVID-19 patients in a tertiary care centre.

    METHODS: A descriptive cross-sectional study was conducted on hospitalised COVID-19 patients from April 2021 to June 2021 in a tertiary care centre. Ethical approval was taken from the Institutional Review Committee (Reference number: 2078/79/05). The hospital data were collected in the proforma by reviewing the patient's medical records during the study period of 2 months. Convenience sampling was used. Point estimate and 95% Confidence Interval were calculated.

    RESULTS: Among 106 hospitalised COVID-19 patients, the prevalence of antibiotic use was 104 (98.11%) (95.52-100, 95% Confidence Interval). About 74 (71.15%) of patients received multiple antibiotics. The most common classes of antibiotics used were cephalosporins, seen in 85 (81.73%) and macrolides, seen in 57 (54.81%) patients.

    CONCLUSIONS: The prevalence of antibiotic use among hospitalised COVID-19 patients was found to be higher when compared to other studies conducted in similar settings.

    Background Point prevalence survey (PPS) on antibiotic use developed by the WHO has already been used in many hospitals globally. Objective To obtain information on antibiotic prescribtion using point prevalence survey methodology in six private hospitals in the Kathmandu valley. Method This descriptive cross-sectional study was completed during 20th July to 28th July 2021 using point prevalence survey methodology. The study was conducted among inpatients admitted at or before 8:00 AM on the day of survey in various wards. Data was presented as frequencies and percentages. Result Maximum number of patients were above 60 years [34 (18.7%)]. Number of male and female participants were equal [91 (50%)]. Only one antibiotic was used in 81 patients (44.5%) followed by two antibiotics in 71 (39%) patients. Duration of prophylactic antibiotic use was one day in 66 (63.7%) patients. Blood, urine, sputum, and wound swabs were the common samples for culture. Cultures were positive for 17 (24.7%) samples. The common organisms isolated were E. Coli, Pseudomonas aeruginosa and Klebsiella pneumoniae. Ceftriaxone was the most used antibiotic. Drug and therapeutics, infection control committee and pharmacovigilance activities were present in 3/6 (50%) study sites. Antimicrobial stewardship was present in 3/6 (50%) and microbiological services was present in all hospitals. Antibiotic formulary and antibiotic guideline were present in 4/6 sites and facilities to audit or review surgical antibiotic prophylaxis choice in 2/6 (33.3%) sites, facility to monitor antibiotic use in 4/6 (66.6%) and cumulative antibiotic susceptibility reports in 2/6 (33.3%) study sites. Conclusion Ceftriaxone was the most used antibiotic. E. Coli, Pseudomonas aeruginosa and Klebsiella pneumonia were the commonly isolated organisms. Not all parameters for infrastructure, policy and practice and monitoring and feedback were present at the study sites. KEY WORDS.

    INTRODUCTION: The access, watch, and reserve (AWaRe) classification of antibiotics was developed in 2019 by the WHO Expert Committee on the Selection and Use of Essential Medicines as a tool to support antibiotic stewardship efforts at local, national, and global levels. The objectives of this study were to assess the availability of antibiotics as per WHO AWaRe classification at community pharmacies located around a tertiary care hospital in Lalitpur and to compare these antibiotics with the national essential medicine list of Nepal.

    METHOD: The cross-sectional study was conducted at community pharmacies located within a two-kilometer radius of a teaching hospital from August to November 2022. A total of 82 community pharmacies registered with the Nepal Chemist and Druggists Association and the Department of Drug Administration were studied. Data was collected using a standard proforma containing the names of the antibiotics classified as per the WHO's AWaRe classification.

    RESULTS: Access group of antibiotics, Ampicillin, (82;100%), Amoxycillin, (82;100%), Flucloxacillin, (82;100%), and Metronidazole, (82;100%) were available in all community pharmacies. Results from the watch group showed that Azithromycin, (80; 97.6%) was available in all pharmacies followed by Cefixime, (80; 97.6%), Ciprofloxacin, (73; 89%), Levofloxacin, (74; 90.2%)and Ofloxacin, (74; 90.2%). Linezolid, (24; 29.3%) was the most common antibiotics available from the reserve group of antibiotics. Colistin was the second commonly available antibiotic. The most available antibiotic from the not recommended group were Ampicillin/Cloxacillin (82; 100%), followed by Piperacillin/Sulbactam, (39; 47.6%). There were differences in the classification of antibiotics between the WHO AWaRe list and the Essential Medicines list of Nepal in terms of numbers of antibiotics listed.

    CONCLUSION: Antibiotics from the not recommended and reserve groups were commonly available in community pharmacies. The implementation of antibiotic guidelines should be emphasized along with strict monitoring of the sale of antibiotics without a prescription in community pharmacy settings.

    BACKGROUND: Dengue is a mosquito-borne viral disease with a wide spectrum of presentations ranging from subclinical disease to severe dengue. Dengue is endemic to the Terai of Nepal. Interestingly, an increasing incidence has been reported from hilly areas like Kathmandu valley. This study explored the clinicopathological profile of dengue infection.

    METHODS: A total of 84 serologically confirmed dengue cases from September to November 2019 at KIST Medical College were recruited in a cross-sectional study after obtaining ethical approval. Dengue was categorized as dengue without warning signs, dengue with warning signs, and severe dengue. Clinicopathological information was recorded in the proforma by reviewing patients' records. A descriptive statistical tool and chi-square test were carried out.

    RESULTS: Out of 84 patients, 76% (64) were dengue without warning signs, 21.4% (18) were dengue with warning signs and 2.4% (2) were severe dengue. About 97.6% (82) presented with fever. During the course of illness, anemia was identified in 38.1% (32), thrombocytopenia in 65.5% (55), hemoconcentration in 6% (5), and leucopenia in 82.1% (69). Similarly, elevated aspartate transaminase and alanine transaminase (ALT) was observed in 67.7% (42) and 53.2% (33) respectively. The severity of dengue on presentation to hospital was significantly associated with thrombocytopenia, leucopenia, and elevated ALT. Similarly, the severity during course of illness in hospital was significantly associated with hemoconcentration, thrombocytopenia, leucopenia, and elevated ALT.

    CONCLUSIONS: Most common presentation of dengue infection was fever. The most common laboratory abnormalities were leucopenia, thrombocytopenia, hemoconcentration, anemia, and elevated liver enzymes. Awareness of these clinical and laboratory parameters is important for the prompt diagnosis, severity estimation, and overall management of dengue infection.

    A survey of awareness and attitudes to the management of fragility fractures among the membership of the Asia Pacific Orthopaedic Association conducted in 2022 found considerable variation in care across the region. A Call to Action is proposed to improve acute care, rehabilitation and secondary fracture prevention across Asia Pacific.

    PURPOSE: Fragility fractures impose a substantial burden on older people and their families, healthcare systems and national economies. The current incidence of hip and other fragility fractures across the Asia Pacific region is enormous and set to escalate rapidly in the coming decades. This publication describes findings of a survey of awareness and attitudes to the management of fragility fractures among the membership of the Asia Pacific Orthopaedic Association (APOA) conducted in 2022.

    METHODS: The survey was developed as a collaboration between the Asia Pacific Osteoporosis and Fragility Fracture Society and the Asia Pacific Fragility Fracture Alliance, and included questions relating to aspects of care upon presentation, during surgery and mobilisation, secondary fracture prevention, and access to specific services.

    RESULTS: In total, 521 APOA members completed the survey and marked variation in delivery of care was evident. Notable findings included: Fifty-nine percent of respondents indicated that analgesia was routinely initiated in transit (by paramedics) or within 30 minutes of arrival in the Emergency Department. One-quarter of respondents stated that more than 80% of their patients underwent surgery within 48 hours of admission. One-third of respondents considered non-hip, non-vertebral fractures to merit assessment of future fracture risk. One-third of respondents reported the presence of an Orthogeriatric Service in their hospital, and less than a quarter reported the presence of a Fracture Liaison Service.

    CONCLUSION: A Call to Action for all National Orthopaedic Associations affiliated with APOA is proposed to improve the care of fragility fracture patients across the region.

    The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set up in 2004 on acute-on-chronic liver failure (ACLF) was published in 2009. With international groups volunteering to join, the "APASL ACLF Research Consortium (AARC)" was formed in 2012, which continued to collect prospective ACLF patient data. Based on the prospective data analysis of nearly 1400 patients, the AARC consensus was published in 2014. In the past nearly four-and-a-half years, the AARC database has been enriched to about 5200 cases by major hepatology centers across Asia. The data published during the interim period were carefully analyzed and areas of contention and new developments in the field of ACLF were prioritized in a systematic manner. The AARC database was also approached for answering some of the issues where published data were limited, such as liver failure grading, its impact on the 'Golden Therapeutic Window', extrahepatic organ dysfunction and failure, development of sepsis, distinctive features of acute decompensation from ACLF and pediatric ACLF and the issues were analyzed. These initiatives concluded in a two-day meeting in October 2018 at New Delhi with finalization of the new AARC consensus. Only those statements, which were based on evidence using the Grade System and were unanimously recommended, were accepted. Finalized statements were again circulated to all the experts and subsequently presented at the AARC investigators meeting at the AASLD in November 2018. The suggestions from the experts were used to revise and finalize the consensus. After detailed deliberations and data analysis, the original definition of ACLF was found to withstand the test of time and be able to identify a homogenous group of patients presenting with liver failure. New management options including the algorithms for the management of coagulation disorders, renal replacement therapy, sepsis, variceal bleed, antivirals and criteria for liver transplantation for ACLF patients were proposed. The final consensus statements along with the relevant background information and areas requiring future studies are presented here.
