Item type:Publication, The Physiological Parameters Among Mountain Hikers(Mongolian National University of Medical Sciences, 2024-03-02); Objectives: This study aims to investigate the impact of outdoor activities, particularly mountain hiking, on physiological parameters, focusing on comparing differences between office workers and professional climbers. By analyzing factors such as waist circumference and exercise frequency, the objective is to assess the potential health benefits associated with active lifestyles and inform strategies for promoting physical activity among sedentary populations. Methods: The survey was collected using a cross-sectional study method from 3 target groups, including professional mountaineers, amateur climbers, and office workers, in October 2022. The main questionnaire of the study included the WHO non-communicable disease risk questionnaire, the frequency and amount of mountain climbing, and the frequency and amount of active exercise. We also measured the physiological parameters of the participants. The statistical analysis was done using SPSS 26.0 software.Results: Engaging in unhealthy habits among office workers causes men to have a higher waist circumference than their standard size, and most do not exercise regularly. In contrast, professional climbers' risk factors for non-communicable diseases were relatively low. Office workers who are inactive and work in conditions that require some physical activity have the greatest need for exercise but are not actively exercising.Conclusion: Outside of work, an individual makes time to climb a mountain, which can positively affect physiological parameters. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Bacterial profile and antimicrobial resistance in patients with pulmonary infection: a retrospective tertiary hospital-based study(Springer Science and Business Media LLC, 2026-07); ; ; ; BACKGROUND: Pulmonary infections remain a major cause of global morbidity and mortality, particularly in low- and middle-income countries (LMICs). The rapid emergence of antimicrobial resistance (AMR) has significantly limited therapeutic options and increased healthcare burden. This study aimed to investigate the bacterial profile and AMR patterns among patients with confirmed pulmonary infections at a tertiary referral hospital in Mongolia, where data from tertiary care settings and internationally disseminated studies on AMR are still scarce, especially in the context of pulmonary infections. METHODS: A retrospective descriptive study was conducted among patients with pulmonary disorders who submitted respiratory specimens for microbiological analysis at Mongolia-Japan Hospital, Ulaanbaatar, between 2023 and 2024. Data were extracted from the electronic medical record (EMR) system. To avoid duplication bias, only the first bacterial isolate recovered from each patient during a single hospitalization episode was included in the analysis. Antimicrobial resistance phenotypes were classified as multidrug-resistant (MDR), extensively drug-resistant (XDR), or pandrug-resistant (PDR) based on the Centers for Disease Control and Prevention (CDC) and the European Centre for Disease Prevention and Control (ECDC) criteria. Clinical characteristics, bacterial profiles, antimicrobial resistance patterns, and clinical outcomes were analyzed. RESULTS: A total of 354 patients were included, of whom 276/354 (78.0%) had an identified bacterial pathogen. The most frequently isolated organisms were Klebsiella pneumoniae 100/276 (36.2%), Acinetobacter baumannii 47/276 (17.0%), methicillin-resistant Staphylococcus aureus (MRSA) 30/276 (10.9%), and Pseudomonas aeruginosa 17/276 (6.2%). Multidrug resistance was observed in 22/30 (73.3%) of MRSA isolates, while 15/47 (31.9%) of Acinetobacter baumannii isolates were classified as PDR. Patients with cardiovascular disease were significantly more likely to harbor MDR isolates (cOR: 2.669; 95% CI: 1.048-6.796). All-cause hospital mortality was higher among culture-positive than culture-negative patients (21/112 [18.8%] vs. 1/34 [2.9%], p = 0.024). CONCLUSIONS: Gram-negative pathogens, particularly Klebsiella pneumoniae and Acinetobacter baumannii, predominated in pulmonary infections and demonstrated substantial AMR. The high burden of MDR/XDR pathogens highlights major therapeutic challenges and underscores the need for enhanced infection control, antimicrobial stewardship, and ongoing resistance surveillance. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Molecular epidemiology of SARS-CoV-2 in Mongolia, first experience with nanopore sequencing in lower- and middle-income countries setting(Wiley, 2023-12); ; ; ; Burged, NatsagdorjBACKGROUND: Coronavirus disease (COVID-19) has had a significant impact globally, and extensive genomic research has been conducted on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) lineage patterns and its variants. Mongolia's effective response resulted in low prevalence until vaccinations became available. However, due to the lack of systematically collected data and absence of whole genome sequencing capabilities, we conducted a two-stepped, nationally representative molecular epidemiologic study of SARS-CoV-2 in Mongolia for 2020 and 2021. METHODS: We used retrospective analysis of stored biological samples from November 2020 to October 2021 and a variant-specific real-time reverse transcription polymerase chain reaction (RT-PCR) test to detect SARS-CoV-2 variants, followed by whole genome sequencing by Nanopore technology. Samples were retrieved from different sites and stored at -70°C deep freezer, and tests were performed on samples with cycle threshold <30. RESULTS: Out of 4879 nucleic acid tests, 799 whole genome sequencing had been carried out. Among the stored samples of earlier local transmission, we found the 20B (B.1.1.46) variant predominated in the earlier local transmission period. A slower introduction and circulation of alpha and delta variants were observed compared to global dynamics in 2020 and 2021. Beta or Gamma variants were not detected between November 2020 and September 2021 in Mongolia. CONCLUSIONS: SARS-CoV-2 variants of concerns including alpha and delta were delayed in circulation potentially due to public health stringencies in Mongolia. We are sharing our initial experience with whole genome sequencing of SARS-CoV-2 from Mongolia, where sequencing data is sparse.Scopus© Citations 1
