Background: Pulmonary alveolar proteinosis (PAP) is a rare lung disorder characterized by the accumulation of surfactant within the alveoli, leading to impaired gas exchange and respiratory insufficiency. Although the disease is uncommon, it significantly affects patients’ quality of life and requires specific diagnostic and therapeutic approaches. Whole lung lavage (WLL) is considered the standard treatment; however, it has not been widely implemented in Mongolia. We report the first successful case of WLL performed for PAP in Mongolia. Case Presentation: A 56-year-old male presented with dyspnea. Chest computed tomography demonstrated a bilateral “crazy paving” pattern. Bronchoalveolar lavage fluid was positive for periodic acid–Schiff (PAS) staining, and anti–GM-CSF antibodies were detected, confirming the diagnosis of PAP. WLL was performed under general anesthesia using a double-lumen endotracheal tube with bronchoscopic guidance. One lung was ventilated with 100% oxygen while the contralateral lung was sequentially lavaged with 800–1000 mL of warm (37°C) saline per cycle until the effluent became clear. A total of approximately 20 liters of saline was used. Result: The procedure was completed successfully without complications. Following treatment, the patient showed marked clinical improvement with reduced dyspnea and increased exercise tolerance. Oxygen saturation improved from 88% to 93%, and spirometric parameters (FVC, FEV₁) demonstrated improvement. Chest imaging revealed a reduction in pulmonary opacities. Conclusion This case demonstrates the successful implementation of whole lung lavage (WLL) in Mongolia and highlights its importance in improving the diagnostic and therapeutic capacity for rare pulmonary diseases such as pulmonary alveolar proteinosis. The procedure resulted in significant improvement in clinical, functional, and radiological parameters, consistent with findings from international studies. Early diagnosis of PAP and the adoption of standardized protocols in accordance with international guidelines are essential to optimize treatment outcomes and enhance patients’ quality of life.

Background: Between 2017 and 2021, the prevalence of obesity among children aged 2-19 years reached 19.7%, affecting approximately 14.7 million children, with rates of 12.7% among those aged 2-5 years and 22.2% among those aged 6-11 years. Globally, dental caries is among the most common non-communicable diseases, often leading to pain, infection, tooth loss, and reduced quality of life. In Mongolia, the prevalence of overweight and obesity among children and adolescents has increased markedly since 2010, beginning at an early age. In 2018, one in six children under five years and one in eight adolescents were overweight. Aim: This study aimed to assess selected non-communicable disease risk factors among children and adolescents. Materials and Methods: A cross-sectional study was conducted in Ulaanbaatar, Mongolia, using Family Health Centers across all nine districts. A total of 622 children aged 6–17 years were included. Anthropometric measurements (weight, height, and waist circumference) were obtained, and body mass index (BMI) was calculated. Oral health examinations were performed to determine the Decayed, Missing, and Filled Teeth (DMFT) index. Nutritional status was classified based on age and sex-specific growth charts into normal weight, overweight, and obesity categories. Results: Among the participants, 10.29% (n=64) were overweight and 9.97% (n=62) were obese. Overweight was more prevalent among girls, whereas obesity was relatively higher among boys (p<0.001). Regarding dental caries, 37.6% (n=234) of participants had no caries (DMFT=0), 48.1% (n=299) had mild caries (DMFT=1-2), and 14.3% had moderate to severe caries (DMFT≥3). The overall prevalence of dental caries was 62.38%, with significant variation by age group: highest in children aged 6-9 years (69.9%) and lowest in those aged 15-17 years (46.1%) (p<0.001). No statistically significant association was found between BMI categories and dental caries status. Although normal weight predominated in the DMFT=0 and DMFT=1-2 groups, logistic regression adjusted for age and sex showed no significant relationship between BMI and dental caries. However, children aged 6-9 years had a significantly higher likelihood of having dental caries compared to those aged 15-17 years (OR=0.39, 95% CI: 0.24-0.63, p<0.001). Conclusions 1. Among the risk factors for non-communicable diseases (NCDs), overweight and obesity were highly prevalent among children, with one in every five children classified as overweight or obese. The prevalence among male children was approximately two times higher than that among female children (p<0.001). 2. The prevalence of dental caries among the study participants was 90.7%, with a mean caries intensity of 6.4, indicating high level of severity. Age-group analysis demonstrated that children aged 6–10 years exhibited the highest prevalence and severity of dental caries, with a prevalence of 93.5% and a mean caries intensity of 7.3.

Background: To prevent and combat the spread of the COVID-19 pandemic, the Government of Mongolia has implemented measures such as movement and time restrictions, social distancing and isolation, closure of schools, kindergartens and public places, immunization, and others. It has caused adverse consequences for people, social relations, and the economy, causing health, social, economic, and humanitarian crises. Not only does this situation, medical students, as frontline healthcare workers, are more susceptible to virus infection. Vaccines against COVID-19 have been researched quickly due to the pandemic and are being used under emergency use authorization. In our country the approach of mixing vaccine doses from different manufacturers was used (fractional doses). Therefore, there is no study on the exposure of medical students to the COVID-19 infection and the adverse effects after receiving a dose of a heterologous vaccine. Objective: To study the exposure to the COVID-19 infection and vaccination status of medical students. Methods: The survey was conducted from November 2023 to December 2023 using a cross-sectional study design, and 170 students who study at ASUSU and live in the dormitory were included. Results: A total of 170 students participated in the study. 55.9% (n=95) of them were in the first year, 22.4% (n=38) were in the second year, 10% (n=17) were in the third year, 7.6% (n=13) were in the fourth year, 2.4% (n=4) were from the 5th year and 1.8% (n=3) were from the 6th year students. 88.2% (n=150) of students were female and 11.8% (n=20) were male. In this study, 37.1% of the students were infected by COVID-19 infection previously. Among them, 50% of the students were infected from family members, 16.7% from the school environment, and 15.2% did not know about the source of infection. 76.2% of the respondents were diagnosed with COVID-19 in a medical institution, and forty-one students answered that they were treated at the hospital. 83% of the cases were treated at home and were cured within 14 days. In contrast, 93.8% of the hospitalized students were treated within four months to 1 year. The current study demonstrates neurological, respiratory, sensory, cardiovascular, psychiatric, digestive, and dermatological symptoms were in 37.6%, 24.1%, 27.6%, 17.6%, 11.8%, 11.2%, and 10% of the students who participated in the study, respectively. For a year or more, symptoms of all organ systems were present, but neurological symptoms appeared to be the highest. 55.9% (n=115) of the enrolled students received 3 or 4 doses of the vaccine, 3.5% (n=6) did not receive the vaccine. In total, 35% (n=60) of the enrolled students experienced side effects and 65% (n=106) had no side effects. Conclusion In this study, 37.1% of the students were infected by COVID-19 infection previously. According to the current study, symptoms related to the nervous system was the most prevalent and 55.9% (n=115) of the enrolled students received 3 or 4 doses of the vaccine. In total, 35% (n=60) of the enrolled students experienced side effects.

BACKGROUNDThe study was based on the reason that skills, attitude and knowledge of the nurses who are working in healthcare organizations do not satisfy customers and to assess undergraduate nursing curriculum.METHOD306 nurses and specialist are involved. Nursing curriculums of Vermont University of USA, Yonsei University of Korea, National College of Nursing, Japan and Ulaanbaatar University of Mongolia are compared and studied with our curriculum.RESULTStudy shows that curriculum contents of School of Nursing, Mongolian National University of Medical Sciences have comparatively less contents of understanding about healthy person, assessment on human, giving advice healthy human, path anatomy, physiology, communication skills.CONCLUSION42% of participants assessed their knowledge at the low level. Curriculum credits of School of Nursing, Mongolian National University of Medical Sciences is 142, comparatively much more than other schools shows that the need of innovation to the curriculum of nursing bachelor degree.

The research on the smoking habits among 8th-to-12th grade students of schools was conducted using a random sampling method among the 13-18 years old school students.Materials and MethodsThe research was performed using a combination of both qualitative and quantitative methods. The quantitative part of the research was performed by conducting surveys among randomly selected secondary school students according to prepared and approved questionnaires. The qualitative study was performed by organizing focus groups based on prepared discussion guidelines. Sampling: the survey participants were students in grades 8-12 from both public and private schools in Ulaanbaatar, the capital city of Mongolia. A total of 1190 students from the 12 secondary schools of 6 districts were selected through random sampling.Resultsto the question of whether the participants have tried to smoke once or twice, 36,1% (407) responded positively. Among these respondents, 49.6% (272) are male and 23.2 (135) are female. This confirms the statistical data that male students are more exposed to the habit of smoking than female students (x2=57.8, p<0.01). The percentage of the currently smoking students is 11.2% (77) of whom 17.9% are male and 4.8% are female. Of the current smokers, 6.8% smoke every day (x2=48.3, p<0.01). The average age of taking up smoking was 14.0[±1.8] of which males students began using tobacco at 13.9[±1.8] years and females at 14.3[±1.6]. Among the smoking students, 10[±2.1]% were from public schools and 17.3[±2.8]% were from private schools (x2=8.1, p<0.01).
