Background: The aging of the world’s population will determine global health trends. According to the 2021 report of the Capital City Health Department, the average life expectancy of the Mongolian population is 71.3 years (male 67.3, female 76.7), the difference between male and female life expectancy is 9.4 years, and elderly people aged 60 and over account for 8.1% of the total population. The report also shows that 6.5% of all outpatient visits are for people aged 60-64, and 9% are for people aged 65 and over, which means that they do not receive adequate health care services. Therefore, it is important to increase the access to and quality of health care services provided to the elderly in order to improve their health and quality of life. Comorbidities that are common among the elderly are one of the pressing issues in the health sector. Aim: We aimed to study the prevalence and risk factors of multi-morbidities among older adults (aged sixty years and over) in urban and rural areas. Materials and Methods: To accomplish our aim, we conducted 156 lifestyle related questionnaires and 18 health related questionnaires among 720 older people in Ulaanbaatar city and rural areas, and created the database. Pearson correlation coefficient was used to determine the relationship between the quantitative influence of factors using single and multi-factor linear (β-coefficient) and binary logistic regression (odds ratio, CI 95%) methods, and p value less than 0.05 was considered statistically significant. The Apriori algorithm in SPSS was used to determine the relationship between multiple chronic diseases in the elderly people. Results: The prevalence of comorbidity was higher in urban areas (48.1%) and rural areas (51.9%), and ageing (urban areas OR: 2.45, 95% CI: 0.9-6.2; rural areas OR: 6.35, 95% CI: 1.47-27.4, P<0.01) was a risk factor of multi-morbidities. Multimorbidity is defined as the presence of 2 or more chronic conditions, and 3, 4, and 5 chronic conditions were co-occurred to older adults with chronic conditions, 28.7% (165). 11 common patterns of relationships in urban areas and 18 common patterns of relationships in rural areas (support (A→B)>3%, confidence (A→B)>30%, lift (A→B)>1) were determined. Conclusion Multimorbidity was different in urban and rural areas, 11 common patterns in urban areas and 18 common patterns in rural areas were determined. It has shown that the prevalence of multimorbidity was different in urban and rural areas.

Background: Iron deficiency (ID) and iron deficiency anemia (IDA) are among the most common forms of anemia worldwide. Although the underlying causes of ID may vary depending on a country’s developmental level, lifestyle, and other factors, blood loss remains the principal cause leading to ID and subsequent IDA. In hemophilia, recurrent bleeding due to deficiencies of coagulation factors (FVIII, FIX, FXI) can lead to ID, which may progress to IDA and adversely affect the quality of life in these patients. The absence of studies evaluating the prevalence of ID and IDA among hemophiliac patients in Mongolia provided the impetus for this investigation. Aim: To assess the prevalence of ID and IDA among patients with hemophilia. Materials and Methods: A cross-sectional study was conducted among 45 patients with hemophilia registered at the Hemophilia Comprehensive Center (HCC), Mongolia-Japan Hospital, Mongolian National University of Medical Sciences. All participants underwent laboratory testing, including complete blood count (CBC) and serum ferritin levels—were performed using the SYSMEX XN2000 and COBAS BM6010 analyzers. Data analysis was carried out using SPSS 27.0 and MS Excel 2010. Results: Among the 45 cases, 41 were Hemophilia A and 4 were Hemophilia B. Reduced serum iron levels were found in 33.3% (15), and low ferritin levels were observed in 22.2%. Detailed blood tests revealed microcytic hypochromic changes in 43.9% (18) of Hemophilia A cases and in 100% (4) of Hemophilia B cases. The overall prevalence of ID was 13.3%, while the prevalence of IDA was 22.2%. Among the IDA cases, 90.0% were classified as mild and 10.0% as moderate. Notably, 80.0% of the IDA cases occurred in children under 15 years of age. Conclusion ID and IDA are common among hemophiliac patients. The high prevalence among children under 15 years of age suggests an age-related predisposition, emphasizing the need to improve disease management and to implement preventive measures against anemia in this population.

Background: Hypokalemia is considered when the serum potassium level is less than 3.5 mmol/L. Clinical research indicates that hypokalemia affects 20% of hospitalized patients, and in 24% of these cases, inadequate interventions result in life-threatening complications. At present, there is no research available on the prevalence, management, and outcomes of hypokalemia in hospitalized patients, which justifies the need for this study. Aim: The study aimed to examine the prevalence of hypokalemia and the effectiveness of its management in hospitalized patients within the internal medicine department, in relation to the knowledge of doctors and resident physicians. Materials and Methods: This hospital-based retrospective study included a total of 553 cases of patients hospitalized in the Internal Medicine Department of the Mongolia Japan Hospital between January 2024 and August 2024. Patients with a potassium level of <3.5 mmol/L were diagnosed with hypokalemia, and the effectiveness of potassium replacement therapy was evaluated according to the method of supplementation employed. Results: The prevalence of hypokalemia among hospitalized patients in the Internal Medicine Department was 9.8% (54 cases). Based on the study criteria, 42 cases of hypokalemia were selected for further analysis, and a total of 118 potassium replacements were performed through oral, intravenous, and mixed methods. Following potassium replacement therapy, 37.3% (44) of patients achieved normalized potassium levels, while 62.7% (74) still had persistent hypokalemia. Conclusion According to the study results, the prevalence of hypokalemia among hospitalized patients in the Internal Medicine Department is 9.8%. The method of potassium replacement and the severity of hypokalemia do not impact the normalization of potassium levels, with the critical factor being the proper dosage of supplementation. The knowledge of doctors and resident physicians regarding hypokalemia is insufficient, and there is a need to implement guidelines and protocols for potassium replacement therapy in daily clinical practice.

Background: This study explores the potential of food industry by-products, such as plant peels, stems, and slags, as valuable sources of lignocellulosic material (LCM), which contains 25-40% xylan. These underutilized resources, often discarded as waste, hold the promise of sustainable applications in biotechnology. By safely extracting xylooligosaccharides (XOS) from LCM biomass, the value of these materials can be significantly enhanced, contributing to green production and supporting sustainable development. XOS, recognized for its prebiotic activity, has been shown to promote the growth of beneficial gut bacteria, making it a vital research area in the fields of food science, medicine, and technology. Aim: To extract and characterize oligosaccharides derived from by-products of the food industry, evaluate their physicochemical properties, and investigate selected biological activities. Materials and Methods: This study utilized microwave pretreatment and enzymatic hydrolysis to isolate and purify XOS from wheat bran and brewers’ spent grains (BSG), provided by Altan Taria LLC and APU CoL, respectively. Microwave irradiation at 200°C for 5 minutes was employed as a pretreatment step, followed by hydrolysis using commercial xylanase (Thermomyces lanuginosus, recombinant Aspergillus oryzae, 2500 BXU/g) at 55°C for 24 hours. The resulting hydrolysate underwent filtration with activated carbon and ethanol precipitation to yield purified XOS. Analytical methods, including FTIR spectroscopy, TLC and HPLC, were used for structural and compositional analysis of the purified oligosaccharides. In vitro tests evaluated the ability of XOS to support the growth of beneficial gut bacteria, including Bifidobacterium spp., Lactobacillus fermentum (ATCC 9338), and Lactobacillus casei (ATCC 344), using XOS-enriched media. Additionally, in vivo studies were conducted on rats to determine the biological effects of XOS on gut microbiota. Results: The results demonstrated that prolonged enzymatic hydrolysis for more than 10 hours, using 0.25 g of xylanase per 100 g of substrate, resulted in optimal yields. XOS purity was measured at 87.6% with an 8.1 g yield from wheat bran and 89% purity with a 7.2 g yield from brewers’ spent grains. Structural analysis confirmed the presence of xylobiose, xylotriose, and xylotetraose, with xylotetraose being the most abundant component in WBP-XOS (47.5%), and xylobiose dominating BGS’s derived XOS (47.8%). Biological effects revealed that wheat bran-derived XOS significantly supported the growth of Bifidobacterium spp. and L. fermentum (ATCC 9338) in a concentration-dependent manner, whereas no significant effect was observed on L. casei (ATCC 344). In vivo studies confirmed that XOS consumption increased populations of Bifidobacterium spp. and Akkermansia muciniphila spp. in gut microbiota (p<0.05). Furthermore, XOS consumption reduced plasma cholesterol, triglycerides, and LDL-C levels while increasing HDL-C levels, demonstrating metabolic benefits. Conclusion This research establishes that XOS with prebiotic activity can be efficiently extracted and purified from food industry by-products using microwave-assisted enzymatic hydrolysis. This approach highlights the potential of utilizing agricultural and industrial waste for producing functional prebiotics, contributing to sustainable practices and offering valuable applications in health and nutrition.

Introduction: Diarrhea is defined as a person excretes more than three times in 24 hours with pathological impurities of more than 10 mg/kg per day. According to the fact sheets of the World Health Organization in 2019, diarrhea is the second leading cause of death among children under 5 years of age. Researchers suggest that about 50 percent of infantile diarrhea occurs in temperate countries and it reaches almost 80 percent in winter which is mainly caused by rotavirus. While immunization is the most effective way to prevent rotavirus infection, there were two types of rotavirus vaccines that have been licensed and available on the global market since 2006. Rotavirus immunization in young children is a safe and effective public health method for controlling rotavirus infection which therefore can reduce childhood morbidity and mortality. Study aim: To study the incidence, clinical manifestations, and complications of rotavirus among children hospitalized with acute diarrhea. Methodology: The study will be conducted using the observational method including descriptive analysis. Statistical data for 2018-2020 will be obtained and analyzed from the pediatric wards of the “Gurvan Gal” hospital. Children diagnosed with rotavirus diarrhea who meet the criteria to be included in the study will be selectively sampled with further analysis of the incidence, clinical features, toxicity, and dehydration of acute diarrhea according to the medical history. Results Universal immunization is important to significantly reduce rotavirus-associated diarrhea, thereby reducing infection and the risk of disease in infants and young children.

Background: Acute appendicitis is an inflammatory disease and acommon cause of acute abdominal pain. The application of the sophisticated automated hematology analyzer more precisely define the morphology changes blood cells. According to this diagnose and treatment control issues are solved by easy and not expensive way. Recent studies haveshown that there is a negative correlation between platelet count (PC) and MPV and that theratio of these two values may be more meaningful. The aim of our study was to investigate thediagnostic value of MPV and the MPV/PC ratio in acute appendicitis. Methods: The patients were divided into two groups based on their histopathological findings: the uncomplicated and complicated appendicitis groups. Leukocyte count, PC, MPV and the MPV/PC ratio were compared all groups. Results: Total of 186 patients, including 119 men, were included in the study. The average age of all patients was 10.21±1.22 years. There was statistically significant difference of some parameters in peripheral blood between the uncomplicated and complicated appendicitis groups in terms of all index. (p<0.001). Leukocyte count had a strong discriminatory property based on the area under curve (AUC) 0.714, (p<0.001). MPV, PC and the MPV/PC ratio had weak discriminatory power with AUC values <0.663. Using receiver operating characteristic (ROC) analysis, the sensitivity and specificity of MPV were 81.56and 45.7%, respectively, and 63.78% and 71.06%, respectively, for the MPV/PC ratio. Conclusions In our study, MPV and the MPV/PC ratio were useful in the diagnosis of acute appendicitis.

Introduction: Sarcopenia is a prevalent condition characterized by decrease in muscle strength and loss of body function which result from the decrease of muscle mass in older age. In 2014, the Asian Working Group for Sarcopenia developed the diagnosis criterion for sarcopenia. The measurements were changed to accommodate for the physical characteristics of asians. The loss of muscle mass increases after age 40 and decreases by 8 percent every 10 years. After age 70 this number is increased to 15 percent every 10 years. Goal: Assess the prevalence of sarcopenia among men by comparing body height and mass Materials and Methods: The study included 196 older men aged 40 and above chosen by random sampling from the geriatric and rehabilitation cabinets of the Mongolian National Gerontology Center.
Sarcopenia diagnosis was made based on the criteria from the Asian Working Group for Sarcopenia using methods by Janssen I and others to compare body mass and height. Results: Comparing body muscle mass and height 11.7 percent of participant aged 40-86 had sarcopenia. When comparing body muscle mass and weigth 33.2 percent had sarcopenia. Conclusion Determining sarcopenia among Mongolian men by comparing muscle mass and body mass resulted in 33.2 percent sarcopenia. When compared with height, 11.7 percent had sarcopenia.
