Background: Numerous studies have shown that air pollution is a serious public health threat and risk worldwide. Mongolia is the world leader in outdoor and indoor air pollution, and the morbidity and mortality caused by it are increasing every year. People spend most of their lives indoors, and it is necessary to regularly assess and study indoor air pollution. Aim: To study the concentration of PM2.5 particles in the indoor air of households in Ulaanbaatar and Darkhan cities in relation to some symptoms of respiratory diseases. Materials and Methods: The study was conducted using an analytical cohort design from October 2023 to July 2025, and the 4 districts of the central Ulaanbaatar city and Darkhan cities were included in the study. A total of 240 households were included in the study, including 48 households living in ger and house, 24 households living in apartments, and 48 households living in ger and house, and 24 households living in apartments from Ulaanbaatar city. A direct measurement device (PurpleAir) was installed in the households for 3-4 weeks to measure PM2.5 particles in the indoor air for 24 hours. After measuring PM2.5 particles in the indoor air of the household, data were collected through questionnaires from the participants aged 18-60 who participated in the study and underwent health examinations. The results were processed using STATA-19.0 and R programs. Result: 213-239 households were selected for the study, including households living in 17-26 apartments, 42-58 houses, and 38-50 houses. The 24-hour average concentration of PM2.5 particles in the ambient air of households in Ulaanbaatar city was measured relatively higher in winter and summer than in households in Darkhan city. Among the districts of Ulaanbaatar city, the highest concentration of PM2.5 particles was measured in Songinokhairkhan district, and the lowest concentration was measured in Bayanzurkh district. Considering the cities by heating type, households with stoves are more polluted than households with centralized heating. In Darkhan city, the lowest concentration was measured in apartments (22.78-31.53 μg/m³), houses (44.53-68.17 μg/m³), and the highest concentration was measured in traditional felt houses (houses) (63.20-68.25 μg/m³). In Ulaanbaatar, PM2.5 concentrations were relatively high in all types of housing, including apartments (41.61-58.37 μg/m³), houses (79.22-92.50 μg/m³), and traditional felt dwellings (76.69-86.31 μg/m³). In the summer, PM2.5 concentrations in Darkhan were 3.10-10.03 μg/m³ in apartments, 7.67-14.37 μg/m³ in houses, and 7.98-17.90 μg/m³ in traditional felt dwellings (houses). The concentration of PM2.5 particles in the ambient air of the settlement is statistically significantly associated with shortness of breath, fatigue, weakness, muscle pain, nausea, palpitations, sneezing, runny nose, conjunctivitis, pain in the eye socket, tearing of the eyes, headache, fever, nasal congestion, cough, loss of appetite, sore throat, phlegm, wheezing, and chest pain. Conclusion The 24-hour average concentration of PM2.5 particles in indoor air in households in Ulaanbaatar and Darkhan cities is higher than the Mongolian standard during winter and is statistically significantly associated with some symptoms of respiratory diseases.

Background: Dysregulation of inflammation underpins chronic cardiovascular, metabolic, neurodegenerative, and neoplastic conditions. Traditional medicine has long utilized medicinal plants to alleviate and treat systemic inflammation. Specifically, Rhodiola rosea L. and Rhodiola quadrifida (Pall.) Fisch. & C.A.Mey. possess anti-inflammatory, antitumor, antioxidant, and anti-angiogenic properties. Saposhnikovia divaricata (Turcz.) Schischk. has been shown to exert anti-inflammatory effects, support musculoskeletal function, and enhance tissue regeneration. Furthermore, Salsola laricifolia Litv. has been studied for its antioxidant, immunomodulatory, and anti-inflammatory activities. Although the individual anti-inflammatory, antioxidant, and antitumor activities of these plants are established, research evaluating the combined effect of their combined extract remains scarce, providing the rationale for this study. Aim: To evaluate the in vitro effects of a combined extract derived from these medicinal plants on the expression of selected pro-inflammatory cytokines. Materials and Methods: A dry combined extract consisting of Rhodiola rosea, Rhodiola quadrifida, Salsola laricifolia, and Saposhnikovia divaricata was prepared at the Chemistry and Technology Sector of the Institute of Pharmaceutical Research, Monos Group. An in vitro inflammation model was established using murine RAW264.7 macrophage-like cells stimulated with lipopolysaccharide (LPS, 100 ng/mL). Cell viability was assessed using the CCK-8 assay, while the output of pro-inflammatory cytokines TNF-α and IL-6 was measured via Enzyme-Linked Immunosorbent Assay (ELISA). Statistical analysis was performed using one-way ANOVA. Result: The combined plant extract demonstrated no cytotoxic effects on RAW264.7 cells across the tested concentration range. In LPS-stimulated RAW264.7 macrophages, the composite extract dose-dependently and significantly suppressed the production of the pro-inflammatory cytokines TNF-α (p<0.001) and IL-6 (p<0.0001). Conclusion 1. The combined extract of Saposhnikovia divaricata, Rhodiola rosea, Rhodiola quadrifida, and Salsola laricifolia exhibited no cytotoxicity in vitro within the range of 50–400 µg/mL. 2. The combined herbal extract significantly suppressed the production of pro-inflammatory cytokines TNF-α (p<0.01) and IL-6 (p<0.001) in LPS-induced RAW264.7 macrophages in a concentration-dependent manner.

Background: Patient safety is a core dimension of healthcare quality and has become a global priority. According to the report by the U.S. Institute of Medicine, between 44,000 and 98,000 deaths occur annually due to medical errors in hospitals. One of the key indicators of patient safety is the Adverse Events (AE), defined as unintended harm to a patient that results from medical care rather than from the underlying disease. The assessment of adverse events is not only a tool for detecting errors but also an active strategy for improving system reliability and safety. Accurate identification of adverse events is therefore essential for enhancing patient safety and serves as a critical performance indicator with financial implications for hospitals. Aim: To determine the incidence of adverse events in referral hospitals and to analyze the relationship between triggers and adverse events. Material and Methods: Data were collected during 2023–2024 from three referral hospitals, the First, Second, and Third State Central Hospitals after obtaining institutional approval. The study was conducted within the framework of the Whole System Measures methodology developed by the Institute for Healthcare Improvement (IHI), which is internationally used for system-wide performance assessment. Data extraction was performed from electronic health records and inpatient departments, and statistical analyses were conducted using SPSS version 25. Results: The study identified 8.3% adverse events per 1,000 patient-days, which is 1.66 times higher than the international reference rate. A statistically significant association was observed between the number of triggers and the occurrence of adverse events, indicating that the use of triggers facilitates the active detection of adverse events. Conclusion The incidence of adverse events in tertiary specialized hospitals was found to be higher than international benchmarks. The application of trigger-based active surveillance proved to be an effective method for identifying adverse events and enhancing patient safety monitoring systems.

Introduction: The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) has increased significantly over the last three decades worldwide, from 17.6% in 1990 to 23.4% in 2019. The development of this disease depends on many risk factors, including genetics, lifestyle, and environment. The PNPLA3 (patatin-like phospholipase domain-containing protein 3) gene is the most relevant genetic factor influencing the risk of metabolic dysfunction-associated steatotic liver disease. The PNPLA3 rs738409 GG genotype impairs adiponutrin function, accumulating triglyceride in liver cells and forming small fat droplets within the liver. Aim: To determine rs738409 and rs2896019 single nucleotide polymorphisms of the PNPLA3 gene in metabolic dysfunction-associated steatotic liver disease and their correlation with some parameters of anthropometric and laboratory tests. Materials and Methods: This study was conducted with a case-control design in 2023–2024. There were 150 participants in the study, 50 in the control group without MASLD, and 100 in the case group with MASLD. The PNPLA3 (rs738409, rs2896019) gene’s single nucleotide polymorphism was identified by the RFLP-PCR technique. All statistical analysis was performed using SPSS 23 software. Categorical variables were described by numbers and percentages, and the numerical variables were characterized by the median (min and max) for the normal distribution, and mean± standard deviation for the non-normal distribution. The statistical tests utilized were the Chi-square test, Fisher’s exact test, student t-test, and Mann–Whitney test. Ethical approval for the survey was obtained from the Medical Ethics Committee under the Ministry of Health Of Mongolia in January 2023. Results: The participants’ average age was 46.73±11.45, with 60% being women (90) and 40% being men (60). Among all patients, the PNPLA3 gene’s single nucleotide polymorphism rs738409 revealed 44.7% (67) CC, 54.7% (82) GC, and 0.7% (1) GG (OR-CG+GG genotype- 2.9, p=0.003). In addition, as a result of determining the PNPLA3 gene rs2896019 single nucleotide polymorphism, the frequency of the TT genotype was significantly higher in the control group than in the case group (48%, 31%, p = 0.042). Conclusion The frequency of CG/GG genotypes rs738409, and rs2896019 of the PNPLA3 gene is higher in the case group, suggesting that they may be more susceptible to MASLD.
