Goal: The purpose of this study is to identify issues of current situation of the health information system in the health care facilities of Mongolia.Materials and Methods: A total 362 users as hospital directors, physicians, nurses, statisticians and IT workers of 105 health care facilities at primary, secondary and tertiary level participated in this study. Data collection methods were generated using a combination of questionnaires and in-depth interview of the users. The statistical analysis was carried out using the SPSS. Outcome measures were calculated with 95% confidence intervals (CI).Results: The survey results were shown that a vertical health information flow regulates in the health sector, internal networks set up and H-info 2.0 software as routine data processing and insurance claims are used in the hospitals of Mongolia. Regarding of e-health software as Computerized Physician Order Entry (CPOE), Drug Information System (DIS), Laboratory Information System (LIS) and Radiology Information System (RIS), 82.6% of the health care facilities used only CPOE. There 50% of the existed e-health software is not integrated in the health care facilities. In the data management, 27.0% of the health care facilities that used e-health applications had no backup solution. 45.5% of total users said that the information technology human resource is insufficient. 70.0% of users responded as there did not any continues training program in health information technology. The study was determined lack of functions and difficulty of using the existed software and inadequate software operation and not user-friendliness are the causes of the most of dissatisfactions. Conclusions: A vertical health information flow, internal networks, routine statistic processing set up and mainly CPOE used in the health care facilities. However there is no integration of e-health software and lack of its capacity. It is required modern integrated health information system in the health sector of Mongolia.

INTRODUCTION:Uterine leiomyomas are the common smooth muscle tumors of female genital tract. Usually theirdiagnosis poses no problem. On the other hand leiomyosarcomas are highly malignant tumors.Distinction between the two poses no problem if the leiomyosarcoma shows significant dysplasia,however at times it may become a serious problem to differentiate between leiomyoma and well–differentiated leiomyosarcoma. Under such circumstances the mitotic count per 100 high powerfields considered by many as the most important criterion of distinction.MATERIAL AND METHODS:To investigate the role of mitotic activity in the growth of uterine leiomyomas, the mitotic count per100 high-power fields and the relation of this to the patient’s age (30 to 54 years) were examined intissue sections of leiomyomas from 130 surgically removed leiomyomatous uteri.RESULTS:The mean mitotic count in submucosal uterine leiomyoma was significantly higher (42.3%) than thatof the other location such as intermural and subserosal leiomyoma. We found the highest mitoticcount in a leiomyoma at the late reproductive aged women (46.1%) at early secretory phase. But therewas not a statistical correlation between women’s age and mitotic activity of uterine leiomyoma.CONCLUSION:Increased mitotic activity in leiomyomas under the late reproductive aged women suggests that thegrowth of these tumors is affected by progesterone level

Aim was to investigate expression of tumor suppressor P53 gene, proliferating Ki-67 protein inordinary and proliferating uterine leiomyomato establish possible usefulness of these two parametersin distinguishing between ordinary leiomyoma and proliferating leiomyoma. Retrospective study of49uterine leiomyoma (25 ordinary leiomyoma, 24 proliferating leiomyoma) technically acceptable foranalysis from years 2010–2013 department of Obstetrics and Gynecology and department of Pathology,Mongolian National University of Medical Science, Ulaanbaatar, Mongolia.MethodAll tissue specimens were obtained from surgically removed tumors. Tissue was fixed in formalinand cut to thickness of 5 mm from paraffin-embedded blocks. All haematoxylineosin slides and allimunohistochemical slides for each case were reviewed by two experienced pathologist.ImmunohistochemistryParaffin-embedded tumor sections were deparaffinized and stained in automated platformDakoCytomationusing monoclonal mouse anti-human Ki-67 antigen (Dako,Glostrup, Denmark), monoclonal mouse anti-humanP53 protein (Dako, Glostrup, Denmark).Immunohistochemicalanalysis of P53 and Ki67 expression was performed. Every nuclei stained brown,regardless of shade intensivity, was considered positive. The interpretation of immunohistochemicalstaining was expressed as number of positive cells in 100 cell count in most active area of the slide.Non-parametric analysis of variance Kruskal-Walistest was performed.P53 expressionExpression of P53 was negative in 24/24 ordinary uterine leiomyoma, 2/10 mitotic activity leiomyoma,11/15 cellular leiomyoma. Expression of P53 in 1–10% of cells showed 3/10(30%) mitotic activeleiomyoma and 1/15(6.6%) cellular leiomyoma. Expression in 10-70% of cells showed 5/10(50) mitoticactivity leiomyoma, 3/15(20%) cellular leiomyoma. A significant difference in expression of P53 wasseen between ordinary and proliferative (mitotic activity and cellular) uterine leiomyoma (p<0.007, Table1).Ki-67 expressionExpression of Ki67 was negative in 20/20 (100%) ordinary leiomyoma, 4/11(36.3%) mitotic activityleiomyoma and 7/18(38.8%) cellular uterine leiomyoma. 1–10% of cells were positive in 4/11 (36.6%)mitotic activity leiomyoma, and 5/18% cellular leiomyoma. Expression was positive in 10-70%of cellsof 3/11(27.2%) mitotic activity leiomyoma and 6/18(33.3%). Statistically significant differences in Ki67expression was found between ordinary leiomyoma and proliferating leiomyoma (p<0.014, Table 2) andbetween LM and LMS (p=0.000, Table 1).Conclusion:The findings of our study in concordance with other study results are helpful information establishingmore diagnostic criteria and parameters for diagnosis in doubtful cases between two entities.Immunoassaying for Ki-67 and P53 are such parameters. The panel of their expression in specific caseeases diagnosis.

Introduction: Pancreatic cancer in young patients is usually correlated with chronic alcohol consumption and hereditary factor. Chronic pancreatitis, pancreatic trauma, pancreatic cyst, alcoholism, and diabetes mellitus are the most clearly established etiological factors (T.Y Flanders., W.S Foulkes., 1996). The cancer was located to the pancreatic head in 75% to the body in 15-20% and to the tail in 5-10% of cases (A.E Richard., 2005). Goal: Determination of the US signs in pancreatic cancer and establishment standard (control) US diagnostic criteria. Objectives: 1. To reveal direct and indirect US signs of pancreatic cancer. 2. To establish standardized US diagnostic criteria. Materials and Methods: A prospective study was carried out in 35 patients with pancreatic cancer in a 4 years period between 2006-2010 (Shastin Central Hospital, Achtan Clinical Hospital). To each patient has being filled special investigation chart. Diagnosis was confirmed on the result of physical examination, laboratory investigation, abdominal conventional radiography, upper gastrointestinal contrast radiography, CT, MRI, ERCP and biopsy. The results of the measurements were compared with the standardized control evaluation of Mongolian people (Ts.Badamsed.B.Tserendash). Results: Our sample represents US signs in 35 patients with pancreatic cancer. On the basis of our study US sign were divided into two categories: direct and indirect signs. Direct signs: a) irregular shape, b) irregular tumour edge, c) hypodensity, d) tumour size more than 2.1cm, e) different location. Indirect signs: a) CBD distends, b) gallbladder distends, c) intra hepatic bile duct distend, d) pancreatic pseudo cyst, e) near-aortic limp node enlargement, f) splenomegaly. We consider that the upper mentioned US abnormality can be as control standard criteria for the US diagnosis of the pancreatic tumour. According to the study of V.N.Demidov and G.P.Sidorov (1987), the pancreatic cancer is located to head in 50-80%. In our series it was about 45.7%± 8.4. Irregular tumour shape in 60.0%±8.3, tumour hypodensity 80.0%±7.2, irregular tumour edge 68.6%±7.8, tumour clear definition 71.4%±7.6 which are the same with N.M. Mukharllyamov (1987). Conclusions: 1. Were described direct and indirect US diagnostic signs in pancreatic cancer 2. The tumor location, shape, size, edge, consistency, intra and extra hepatic bile duct distend, gallbladder distend, near-aortic limp node enlargement are the basic control criteria for the diagnosis of pancreatic cancer.

PurposeThe aim of our study is to investigate the relationship between cognitive status, depression level,functional status and quality of life in elderly people living at home and in Batsumber.Methods158 voluntary elderly subjects, older than 60 ages were included in the study. The data was obtained byface to face interviews. The questionnaire covered socio-demographic characteristics, administrationof the standardized Mini mental test (SMMT), Geriatric Depression scale (GDS), Lawton instrumentalactivities of daily living (IADL) scale and World health organization Quality of life instrument-olderadults module (WHOQOL-OLD). Data analysis was performed using SPSS 22 software.ResultsThe living at their own home subjects (77.4%) had a high cognitive level and the living in nursing homesubjects (88.2%) low cognitive level. In both groups appeared in high levels of depression. Therewas a positive correlation between IADL, cognitive status and quality of life (p<0.05) and a negativecorrelation between cognitive status, quality of life and depression status.Conclusion: Our results suggest that elderly are more susceptible to the risk of developing psychiatricproblems especially depression. And this study indicated importance of the relationship betweenfunctional level, cognitive status, depression level and quality of life of elderly people living at homeand in Batsumber.

Purpose: The etiology of Legg-Calve-Perthes disease (LCPD) remains unknown until today. A few studies have suggested passive smoke inhalation may be a risk factor, although the association is not confirmed and a causal relationship has not been established. Most mothers who smoke during pregnancy may continue smoking after giving a birth, it would be difficult to determine to what extent passive smoke inhalation adds to the risk of LCPD in these children. The causes of Legg-Calve-Perthes disease are largely unknown, but this pediatric disease seems to result from interruption of the blood supply to the proximal femur and is considered a vascular disease. Because maternal smoking during pregnancy influences fetal development and is associated with cardiovascular diseases in offspring, we hypothesized that this exposure and passive Tabaco smoke exposure are risk factors for Legg-Calve-Perthes disease and also investigated other markers of impaired fetal development and early-life exposures. Methods: We prospectively recruited total 96 patients, among those 32 patients with LCPD as a case group and 64 patients attending the hospital for other orthopedic complaints as control group. Conditional logistic regression was used to assess the association between the exposures and risk of LCPD. Results: The main risk factors for LCPD were family background, indoor use of a wood stove, having a family member who smoked indoors (passive smoke) and smoke during pregnancy. Children from the middle socioeconomic group appeared to be at a greater risk of developing LCPD. Conclusions This study provides further evidence that environmental tobacco smoke is associated with an increased risk of LCPD. Family background and exposure to wood smoke also appears to be risk factors. Maternal smoking during pregnancy and other factors indicated by impaired fetal development may be associated with an increased risk of Legg-Calvé-Perthes disease. However, it remains unclear why there are profound differences in the incidence of the disease between regions when the prevalence of smoking is comparable and why bilateral involvement is infrequent, and it needs further study.

Background: It is stated in the Government Programme of 2016-2020 that public servants, including health care workers, shall be given a gradually increased salary based on their skill, dexterity, workload, and productivity, and such increase started from 2018 as planned. In the health sector of our country, regarding demand and regulation of the programme, the change shall be made that the system for median salary of physicians and overall staff employed at hospitals gets even constructive, and the required human resource for the sector shall be prepared. Thus, inferring from these claims, median salary, real wage, and socioeconomic condition are in critical need for further evaluation. Objective: To examine the current socio-economic condition of health care workers, and to study the influencing factors at play. Methods: In this study, we used quantitative and qualitative methods. In the survey, we involved 655 health care workers from 6 family health centers, 2 district hospitals, 3 health centers (district-based) in Songinokhairkhan, Sukhbaatar, and Baganuur districts; and Provincial hospital, regional diagnosis and health center, 16 soum health centers from Khovd, Uvs, Arkhangai, Bulgan, Khentii, Dornod, Umnugovi, and Dornogovi provinces, along with 3 National specialized health centers and 1 National central hospital. As for data gathering for the qualitative analysis, 30 focus group interviews and 47 key informant interviews were conducted for the purpose of examining socioeconomic condition, real wage sufficiency of health care workers. Results: Average household income of study participants was 1,880,269 tugrik, the real wage was 1,073,065 tugrik, and the overall household is seen to be composed of 2 different sources on average, namely, self-wage and the income coming from family members or supplement of Child Money Programme. It has come to notice that 19.5% of the participants have lower than average living standard, 89.2% have 2 different loans (mortgage, auto loan or mobile application based loans). Material deprivation index is seen to be 2.73, hence deemed as insufficient. In order to increase the real wage of those workers, it shall be taken into consideration that the basic salary is low, and some financial supplements need to be given. Furthermore, the performance based funding system of health sector is seen to be in need of improvement. Conclusion Real wage of the health care workers is, thus, insufficient. The fact that one in every five workers in this sector have lower than average living standard, and the material deprivation index is 2.73 implying that the financial lives of health care workers are immensely fragile.

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: Psychosocial work environment predicts a range of health risks including sickness absence, poor self rated health, and depression. Objective: To identify association between psychosocial work environment and health related indicators among health care workers in Mongolia Methods: A cross-sectional study was conducted between January and April, 2023. 655 health care workers from Ulaanbaatar city and 4 aimags were involved. Psychosocial work environment was assessed by the Effort-reward imbalance model. As for the health related indicators, we used the SF-12 questionnaire and sickness absence report. Descriptive and inferential statistical analyses were performed.
The study was approved by Medical Ethics Review Committee on January 18, 2023 (#23/02). Results: 1 in every 2 health care workers experience effort-reward imbalance at work and rated their health as poor. In average, 32.7 percent of the study participants took 16.6 sick days for the last 1 year. The study identified poor physical (44.7±8.6) and mental health functioning (42.1±9.8) among study participants. Physical functioning was lower among nurses whereas mental health functioning was lower among physicians. Conclusion Poor health related indicators among health care workers are associated with adverse psychosocial work environment such as effort-reward imbalance and high effort and low reward
