Introduction: Safe and accessible WASH services in healthcare facilities are crucial for maintaining high quality care, especially for maternal and newborn health. The WHO-UNICEF JMP on Water Supply, Sanitation, and Hygiene provides reports on progress in water supply, sanitation, and hygiene services at global, regional, and national levels, covering populations, schools, and healthcare facilities. This assessment was conducted to address the insufficient data on the level of hand hygiene services in healthcare facilities, following the methodology of the JMP. Materials and Methods: A cross-sectional study was conducted in 319 healthcare facilities. Availability of hand hygiene services in the study healthcare facilities was assessed using questionnaire of methodology of the JMP. Data were analyzed using SPSS 25.0 software. Relevant parametric and non parametric statistical analysis were conducted. Results: Overall, 72% and 28% of healthcare facilities had basic and limited hand hygiene service respectively. About 18% of private healthcare facilities had limited hand hygiene service compared to 34% of state healthcare facilities. While 20% of urban healthcare facilities had limited hand hygiene service, 56% of rural healthcare facilities do. When examining the level of hand hygiene services by type of medical care, specialty hospitals have 100% basic services. Among primary care facilities, 83% of family health centers provide basic services, while 41% of soum and village health centers meet these standards. Conclusion The basic hand hygiene services in urban healthcare facilities and specialty hospitals were generally sufficient. There need to enhance basic hand hygiene service at the soum and village level. Among the assessed facilities, 81.0% met four out of the five key hand hygiene requirements outlined in the national standard. However, additional budget allocation for maintenance and operational costs for keeping soap and sustaining water running remains crucial to ensure sustained compliance and quality.

Human echinococcosis is a zoonotic disease (a disease that is transmitted to humans from animals) that is caused by parasites, namely tapeworms of the genus Echinococcus. A number of herbivorous and omnivorous animals act as intermediate hosts of Echinococcus. They become infected by ingesting the parasite eggs in contaminated food and water, and the parasite then develops into larval stages in the viscera. Alveolar echinococcosis usually occurs in a wildlife cycle between foxes or other carnivores with small mammals (mostly rodents) acting as intermediate hosts. Domesticated dogs and cats can also act as definitive hosts. Human infection with E. granulosus leads to the development of one or more hydatid cysts located most often in the liver and lungs, and less frequently in the bones, kidneys, spleen, muscles and central nervous system. In endemic regions, human incidence rates for cystic echinococcosis can reach more than 50 per 100 000 person-years, and prevalence levels as high as 5%–10% may occur in parts of Argentina, Peru, East Africa, Central Asia and China. In livestock, the prevalence of cystic echinococcosis found in slaughterhouses in hyperendemic areas of South America varies from 20%–95% of slaughtered animals. The highest prevalence is found in rural areas where older animals are slaughtered. Depending on the infected species involved, livestock production losses attributable to cystic echinococcosis result from liver condemnation and may also involve reduction in carcass weight, decrease in hide value, decrease of milk production, and reduced fertility. Ultrasonography imaging is the technique of choice for the diagnosis of both cystic echinococcosis and alveolar echinococcosis in humans. This technique is usually complemented or validated by computed tomography (CT) and/or magnetic resonance imaging (MRI) scans. The choice must primarily be based on the ultrasound images of the cyst, following a stage-specific approach, and also on the medical infrastructure and human resources available. Worldwide, there may be in excess of 1 million people living with these diseases at any one time. Many of these people will be experiencing severe clinical syndromes which are life-threatening if left untreated. Even with treatment, people often face reduced quality of life. For cystic echinococcosis, there is an average of 2.2% post-operative death rate for surgical patients and about 6.5% of cases relapse after an intervention, thereby requiring prolonged recovery time.

Background: An estimated 99% of the global population lives in environments where PM2.5 levels exceed the WHO air quality guideline of 15 μg/m³. In 2018, air pollution contributed to approximately 4.2 million deaths worldwide. In Mongolia, air pollution—particularly in urban centers like Ulaanbaatar, worsens significantly during the winter season, posing a serious public health and local concern. Therefore, it is compulsory to compare the outdoor air quality in Ulaanbaatar, the capital and Darkhan city. Aim: To assess and compare the outdoor PM2.5 concentrations in Ulaanbaatar and Darkhan during the winter season. Materials and Methods: This study was conducted in Ulaanbaatar and Darkhan from December 10, 2024, to February 19, 2025. A total of 60 PurpleAir Classic+ sensors (30 per city) were installed to assess PM2.5 concentrations at 2-minute intervals. We analyzed collected data using R software. The 24-hour average PM2.5 concentrations were compared with both the Mongolian National Air Quality Standard (MNS4585:2016) and the WHO air quality guidelines (2021). Results: The 24-hour average PM2.5 concentration in Ulaanbaatar was 112.3±62.2 μg/m³, which was significantly higher than that in Darkhan (79.2±25.6 μg/m³; p<0.05). In Ulaanbaatar, the monthly averages were 119.9±67.7 μg/m³ (Decem ber), 113.5±60.8 μg/m³ (January), and 95.0±51.9 μg/m³ (February) respectively (p<0.05). In contrast, Darkhan city’s monthly average PM2.5 remained relatively close across the months: 79.1±22.2 μg/m³ (December), 78.7±28.6 μg/m³ (January), and 84.6±30.0 μg/m³ (February), with no statistical significance (p>0.05). During the study period, the 24-hour average PM2.5 concentrations exceeded the MNS4585:2016 (50 μg/m³) in 69.8% of days in Ulaanbaatar and 64.6% in Darkhan. WHO’s guideline of 15 μg/m³ was exceeded 93.4% of the time in both cities. Conclusion Darkhan city has lower PM2.5 concentrations compared to Ulaanbaatar, both cities significantly exceeded MNS4585:2016 standard and the WHO air quality guidelines (2021) during the winter months.

Background: According to the World Health Organization (WHO), 99 percent of the world’s population is exposed to air that exceeds WHO recommendations, with low- and middle-income countries being the most affected. The main causes of indoor air pollution include human activities such as fuel burning, cooking, cleaning, and smoking; housing characteristics such as walls, floors, ceilings, and furniture; ventilation; and outdoor air pollution. Aim : To assess PM1 and PM10 concentrations in 120 selected households in Ulaanbaatar. Materials and Methods : Indoor PM1 and PM10 concentrations were measured using Purple Air real-time sensors in randomly selected Ulaanbaatar households between October 2023 and January 2024. Supplementary data on factors affecting the PM2.5 concentration were collected via questionnaires. Each measurement was taken in 10-minute intervals, yielding 51,309 data for analysis. Results : PM1 concentrations were measured at 55.5±53.2 μg/m³ in gers, 54.9 ± 46.7 μg/m³ in houses, and 31.6±40.1 μg//m³ in apartments (p<0.001) and measuring PM10 concentrations were 110.6±108.6 μg/m³ in gers, 110.6±96.7 μg/m³ in houses, and 62.2±83.0 μg/m³ in apartments (p<0.001) When considering the concentration of PM1, PM10 by heating type, PM1 was 55.3±50.1 μg/m³ and PM10 was 110.6±103.0 μg/m³ in households with stoves and furnaces, and PM1 was 31.6±40.1 μg/m³ and PM10 was 62.2±83.0 μg/m³ in households connected to the central heating system (p<0.001). Regarding the months of measurement, the highest concentration was observed in December 2023, at 77.1±94.1 μg/m³. The highest concentrations for both PM₁ and PM₁₀ were recorded in January 2024, at PM₁: 64.8±55.1 μg/m³, PM₁₀: 131.4±116.0 μg/m³. Conclusion 1. Indoor PM10 concentrations in residential environments in Ulaanbaatar city were within the MNS4585:2016 Air Quality Standard, however, it was exceeded the WHO air quality guidelines, indicating an excessive risk of increasing morbidity and mortality among the population. 2. Indoor PM1 and PM10 concentrations in residential environments in Ulaanbaatar varies depending on location, type of housing, type of heating, and month of measurement.

Background: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder characterized by degeneration of upper and lower motor neurons, leading to muscle weakness, spasticity, dysarthria, and dysphagia. Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an autoimmune-mediated neuropathy that primarily affects nerve fibers specifically myelin sheets. Clinically, CIDP presents with distal muscle weakness, prominent sensory disturbances, and diminished or absent deep tendon reflexes. The co-occurrence of ALS and CIDP is exceptionally rare and poses significant diagnostic and therapeutic challenges due to overlapping and distinct clinical features. A Case: A 44-year-old male presented to the Department of Neurology at the Mongolia-Japan Hospital, Mongolian National University of Medical Sciences, with progressive muscle weakness in both upper and lower extremities, along with dysphagia, especially for solids with frequent choking episodes. The initial symptoms began in May 2023 with muscle fasciculations, followed by progressive weakness, initially in the right upper limb and gradually progressing to the left. By August 2023, the patient developed bilateral arm weakness, dysarthria, and worsening dysphagia. From August 2024, episodes of head drop were noted. A progressive weight loss of 11 kg was recorded since January 2024. Comprehensive neurological evaluation, including antibody profiling, electromyography (EMG), and nerve conduction studies (NCS), supported a diagnosis of amyotrophic lateral sclerosis with chronic inflammatory demyelinating polyradiculoneuropathy-like neuropathy. Outcome: One month after hospital discharge, the patient demonstrated improvement in self-care abilities and increased muscle strength in both proximal and distal upper limb muscles. Notably, there was marked improvement in overall clinical status. Conclusion To our knowledge, this is the first reported case in Mongolia documenting the simultaneous presentation of ALS and CIDP-like neuropathy. Globally, such cases are exceedingly rare. Timely and accurate diagnosis, along with appropriate treatment, contributed to improved clinical outcomes and a deceleration of disease progression in this patient.

Background: Since ancient times, humans have used medicinal plants for medicinal purposes, and they have been recognized as beneficial to health. The basis of the treatment of these plants is phytochemical substances and in modern times, with the development of science and technology, the substances contained in these plants are extracted and medicinal substances and drugs are produced to treat many diseases. There are more than 800 medicinal plants in Mongolia, and their chemical structure and properties are studied in detail, biological activity and main features are discovered, and new medicines are produced. From the Thalictrum squarrosum plant, 25 compounds have been identified, such as triterpenoids with 17 carbon atoms in the cycloartane type ring, saponins, oleic acid glycosides, phytosterols and their glycosides etc., and the structures of 7 new compounds have been determined and the research on phenolic compounds and antioxidant activity has been limited, which is the basis for this research. Aim: Determination of total phenolic content and antioxidant activity of Thalictrum squarrosum. Materials and Methods: Total phenolic compounds were determined spectrophotometrically using Folin-Chicolte color reagent in 1.0 raw material of the Thalictrum squarrosum. Antioxidant activity was determined by DPPH, FRAB and ABTS in sub-extracts of 4 groups. Results: The total phenolic compounds of Thalictrum squarrosum were determined to be 1.9±0.001%. In the study of biological activity of Thalictrum squarrosum plants, the antioxidant activity of 4 groups of sub-extracts was tested by DPPH method, and the IC50 of total alkaloids (pH 9-10) was 201.58±0.1 μg/ml, ethyl acetate sub-extract 94.34±0.66 μg/ml, aqueous extract 824.18±0.08 μg/ml, and butanol sub-extract 128.75±0.58 μg/ml. When tested by ABTS method, the IC50 of total alkaloids (pH 9-10) was 35.83±0.44 μg/ml, ethyl acetate sub-extract 90.45±0.62 μg/ml, aqueous extract 104.19±0.93 μg/ml, dichloromethane sub-extract 156.44±0.48 μg/ml, and butanol sub-extract 170.03±0.61 μg/ml. When tested for antioxidant activity at 800 μg/ml by the FRAB method, the ethyl acetate sub-extract was 8946.16±14.79 μg/ml, the dichloromethane sub-extract was 1670.12±39.28 μg/ml, the butanol sub-extract was 4863.97±25.98 μg/ml, and the total alkaloids (pH 9-10) were 4897.99±58.12 μg/ml. Conclusion The ethyl acetate extract of the plant Thalictrum squarrosum has been found to be highly antioxidant active and total phenolic compound was 1.9±0.001%.

Background: Type 2 diabetes has increased risk of heart failure 2-4 times more than those in non-diabetic subjects. The early detection of asymptomatic ventricular dysfunction by using NT-pro BNP test in diabetic patients is the best strategy for decreasing morbidity and mortality of heart failure. Aim: The aims of this study were to detect asymptomatic cardiac ventricular dysfunction by using NT-pro BNP test in subjects with type 2 diabetes and to define the factors associated with elevated NT-proBNP. Materials and Methods: This cross-sectional study was included diabetic and non diabetic subjects aged from 35- to 64 years, who had no clinical symptoms of heart failure. Cardiovascular risk factors were detected by clinical examinations. NT-pro BNP determination was performed on an immunoassay analyzer (FIA1100, Getein Bio Medical Inc, China), which uses reagent strip to obtain quantitative NT-pro BNP results in plasma. The cut-off point for NT-pro BNP was 300 pg/ml. Results: A total of 536 subjects without clinical symptoms of heart failure were included in the study of which, 150 were diabetic and 386 were non diabetic. The mean age was 52.8 ± 7.8 years and 281 (52.4%) were females. Cardiac ventricular dysfunction was detected in 7.3% of diabetic and 5.2% of non diabetic subjects. Cardiac ventricular dysfunction in diabetic subjects was increased with age and non-significantly higher in females than in males (8.3% vs 6.4%, p>0.05). In the logistic regression analysis, uncontrolled hypertension (OR 3.80, 95% CI 1.07–13.44), long duration of disease (OR 5.30, 95% CI 1.36-20.66), and ageing (OR 5.40, 95% CI 1.29–22.88) were significantly correlated cardiac ventricular dysfunction in subjects with type 2 diabetes. Conclusion Cardiac ventricular dysfunction in subjects with type 2 diabetes was detected 1.4 times more than those in non diabetic subjects. The likelihood of positive NT-pro BNP test in subjects with type 2 diabetes was independently (p<0.05) associated with advanced age, uncontrolled hypertension and long duration of diabetes.

Background: According to the World Health Organization (WHO), air pollution was responsible for 8.1 million deaths globally in 2021, making it the second leading cause of death, including among children under 5 years old. Air pollution is also linked to a range of diseases such as stroke, chronic obstructive pulmonary disease, lung cancer, and asthma. In Ulaanbaatar, the capital of Mongolia, the average daily concentration of PM2.5 particles in the air reaches 750 μg/m3 during winter, which is 50 times higher than the WHO’s recommendation, making it one of the most polluted cities in the world. Air pollution continues to pose a significant public health challenge not only in Mongolia but also in many countries globally. However, there is a lack of comprehensive research and studies that summarize and review the existing work in this field. Aim: To summarize and review thematic works on air pollution conducted by researchers from Mongolian universities. Materials and Methods: A systematic review and analysis were performed on thematic works by researchers who completed their master’s and doctoral degrees in the field of air pollution between 2011 and 2024. Results: In terms of the type of master’s and doctoral dissertations, 76.0% (n=19) were master’s theses and 24.0% (n=6) were doctoral dissertations. Among the total number of works included in the study, 36.0% (n=9) focused on the health effects of air pollution, while 64.0% (n=16) addressed other related areas. Some studies indicated that PM2.5 levels in the air between 2011 and 2024 were 1-6 times higher than the Mongolian standard, with the highest levels observed from November to February and the lowest in July. Additionally, some studies suggested a reduction in PM2.5 levels following the introduction of improved fuel in Ulaanbaatar. Air pollution was found to increase the risk of respiratory and cardiovascular diseases, as well as cancer, and to contribute to reduced fetal weight. Conclusion When examining thematic studies on air pollution conducted by state-owned universities in Mongolia, the primary focus has been on the composition, concentration, and health impacts of air pollution. Going forward, research aimed at mitigating air pollution should be driven by collaborative efforts and leadership from universities, with the results being effectively communicated to policymakers.

Background: Accreditation of healthcare institutions serves as a fundamental mechanism for ensuring patient safety and validating the quality of medical services provided to the population. At Intermed Hospital, a quality measurement system for healthcare services has been established since 2015, encompassing 126 quality indicators at both institutional and departmental levels. This system facilitates continuous quality improvement efforts. In this context, quality indicators specific to the endoscopy department play a pivotal role in objectively assessing the quality of endoscopic services. Aim: To assess the quality indicators in gastrointestinal endoscopy unit. Materials and Methods: A retrospective single-center study was conducted by collecting data from the Intermed hospital’s electronic information systems which included HIS and PACS and Quality and Safety Department’s Database and the results were processed using the SPSS software. Ethical approval was granted by the Intermed hospital’s Scientific research committee. The quality of endoscopic services in the Intermed hospital was assessed based on: a) the average values of four quality indicators measured monthly; b) sample survey data from five categories of quality indicators. Results : Between 2016 and 2024, the quality indicators of the endoscopy unit measured as the level of early warning score evaluations for patients was 95.97%±3.33, the level of cases where peripheral blood oxygen saturation decreased during sedation was 1.54%±3.78, the level of cases where patients experienced paradoxiical response during sedation was 5.82%±1.75, surveillance culturing level for validation of endoscopy reprocessing was 11.6%. The endoscopic documentation quality by peer review showed 95.7-100%, the colonoscopy quality indicators were followings as adenoma detection rate: 24.5% Cecal intubation rate: 99.1%, 95.2%, Colonoscope withdrawal average time: 13.28±10.62 minutes, Bowel preparation quality (Boston Scale): 89.3% 95.7%), patient discharge from the recovery room, Average discharge time post-procedure: With propofol alone: 30.92 minutes; With propofol and fentanyl combined: 31.52 minutes, The intermediate risk was 0.28% by the TROOPS evaluation during procedural sedation. Conclusion The quality benchmark levels for these endoscopic units, as determined by a single-center study, can be effectively implemented by benchmark endoscopy centers to enhance their quality and safety operations.

Background: According to the World Health Organization (WHO), 6.7 million people die annually due to air pollution caused by solid fuel use, with the majority of deaths resulting from respiratory diseases and cardiovascular conditions. In Mongolia, air pollution ranks as the fourth leading risk factor contributing to mortality, following hypertension, diabetes, and other major health risks. Although there have been numerous studies on outdoor air pollution in Mongolia, research linking indoor air pollution at the household level with the health status of residents remains limited. Aim: To compare indoor PM2.5 concentrations in households of Ulaanbaatar and Darkhan and examine their association with hypertension during the winter season. Materials and Methods: The study was conducted during November and December 2023, and January 2024, involving 240 households in Ulaanbaatar and Darkhan. Indoor PM2.5 concentrations were measured using Purple Air real-time sensors continuously for 24 hours over approximately one month. After measuring indoor air pollution, individuals aged 18–60 years living in the selected households were recruited based on specific inclusion criteria. Blood pressure was measured three times and the average value was recorded. Information on respiratory illnesses was collected through structured questionnaires. Statistical analysis was performed using STATA version 19.0. Results: A total of 241 households participated in the study, with 116 from Ulaanbaatar and 125 from Darkhan. Of the participants, 46.5% were male and 53.5% were female. In terms of housing type, 96 households (39.8%) lived in gers, 97 (40.2%) lived in stove-heated houses, and 48 (19.9%) lived in apartments. Among all participants, 66.0% (n=159) had hypertension and 34.0% (n=79) had normal blood pressure. Among participants aged over 40, 69.9–88.5% had hypertension, which is statistically significantly higher compared to younger individuals (p=0.0001). By body mass index, 75.3% (n=72) of overweight individuals and 78.4% (n=58) of obese participants had hypertension, showing a statistically significant difference compared to participants with normal weight (p=0.0001). The 24-hour average concentration of indoor PM2.5 was measured using the Purple Air device, and the levels in gers and stove-heated houses exceeded the limit set by the MNS 4585:2025 standard (37.5 µg/m³) Conclusion This study identified a relationship between environmental factors, such as air pollution and housing type, and the prevalence of hypertension. The indoor PM2.5 concentration in gers and stove-heated houses was above the standard limit, indicating a negative impact on the health of those residents. Furthermore, the high prevalence of hypertension among participants over the age of 40 and those who are overweight suggests a possible link to lifestyle and environmental conditions.
