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, Demographic and Occupational Factors Associated With Silicosis in Workers in Gold Mines in Mongolia: A Cross-Sectional Study(The University of Occupational and Environmental Health, Japan, 2026); ; ; ; Understanding country-specific demographic and occupational factors is crucial in optimizing silica exposure control measures. This study investigated demographic and occupational factors associated with silicosis in workers in gold mines in Mongolia. This cross-sectional study was conducted in July 2024 at two private gold mining companies in Mongolia's western regional provinces. In total, 147 participants completed pre-administered questionnaires. Silicosis was diagnosed by chest X-rays, which were interpreted based on the International Labour Organization classification system. Associations between risk factors and silicosis were evaluated with logistic regression. The prevalence of silicosis was 16.3% (24 cases). Participants aged 30-39 years were at significantly higher risk than other age groups (adjusted odds ratio [OR] 5.40, 95% confidence interval [CI] 1.32-21.97). Those engaged in loading explosives and blasting had a 5.3-fold increased risk compared with those performing other tasks (95% CI 1.28-22.32). High cumulative exposure to dust, defined by longer working years and daily exposure hours, was strongly associated with silicosis (adjusted OR 5.52, 95% CI 1.19-25.52). Use of N95 masks did not demonstrate a statistically significant protective effect. Our findings highlight the need for enhanced silica exposure control measures. Possible measures include limiting working hours and cumulative exposure durations, and implementing engineering controls (e.g., ventilation and water suppression systems) to reduce airborne silica levels, especially for those engaged in loading explosives and blasting. Such interventions are important in reducing the burden of silicosis in the Mongolian gold mining industry.Scopus© Citations 1
