IntroductionCardiovascular diseases are among the first three causes of mortality in the global population. 1 billion people in the world suffer from arterial hypertension2. In USA 60 million people have high arterial blood pressure, while 40% of the adult population of Russia have arterial hypertension. In Mongolia 28% of the adults suffer this disease. For most countries, arterial hypertension is both health and social problems. Studies of research centers in the USA and Western European countries demonstrate that decreasing the prevalence of arterial hypertension diseases can prolong the life expectancy3. There is an increasing trend of cardiovascular diseases in the Gobi region on Mongolia (10000:645.63 in Umnugobi aimag) with no tendency to decrease predicted in the near future4,5.ResultsWe conducted the study in order to define the intermediate risk factors causing the cardiovascular diseases on the aimag and soum levels. The study involved 754 people over the age of 30 years from 14 soums of 4 aimags. Of these participants, 26.3% are males and 73.7% are females. Our study shows high prevalence of arterial hypertension among the population, particularly among the working age population. A majority of the people over 30 years old taking park in our study had a low level of education, lower than minimum living standard income and unemployed. Among the people aged over 30 years, every fifth person uses tobacco and every seventh abuses alcohol and it shows that there is high index of alcohol and tobacco use among the population. 92.4% of the reviewed used less than 5 units of fruits and 90.8 of them used less than the same units of vegetables.ConclusionThus, the Gobi region population consumes insufficient quantity of fruits and vegetables with the entire food pattern being generally unhealthy. Hypodynamia is common among the population varying across the ages, sexes, occupation groups and locations. The average systolic and diastolic pressures are higher in men than in women. The prevalence of overweight and obesity is high due to lack of physical exercising, weight control and optimization of food intake. As to the genders, women have a higher risk for overweight. Blood cholesterol and triglyceride levels are higher in men. The correlation between arterial hypertension and consumption of alcohol and tobacco, obesity and overweight and hypodynamia is strong.

BACKGROUND Inflammation, ulcer and cancer are the popular diseases of stomach. The number of stomach cancer was placed on the second place after liver cancer and if reached a peak of 14,7% of all kind of cancer. Unfortunately, the number of these cases about stomach cancer took the second place, also the number of death caused by stomach cancer took the first place by it is happening. In Mongolia, because of stomach cancer around 500 people pass away. Helicobacter infection is considered as a main reason of stomach cancer and besides that, there are so many influencing factors such as smoking habits, nutrite, abuse of salt, genetic parameters. METHODS 537 patients have endoscopy done and 121 of them have analyze of helicobacter infection taken randomly in the 1st season of 2017 in gastroenterology department of Medipas hospital. The number of patients who have taken helicobacter analyze was computed by theorem of Japanese scientist Taro Yamane. Results of research was processed by spss-v.24. RESULTS 65 of patients, who were participated in this research were male and other 56 were female. Most of them were at the age between 40-50. 64% of them haven’t known about helicobacter and have never taken this analyze, 36% of them have taken analyze helicobacter in blood but they haven’t treated fully and haven’t known about infection of helicobacter by the way of transferring.

INTRODUCTION:Waterborne diseases, especially diarrhea, related to water quality and safety, personal sanitation and hygienehave been still reported very high in developing countries. Globally, there are an estimated 1.4 million casesof hepatitis A every year. The hepatitis A virus is transmitted through ingestion of contaminated food and wateror through direct contact with an infectious person. Hepatitis A is associated with a lack of safe water and poorsanitation [2].Dysentery is bloody diarrhea, i.e. any diarrheal episode in which the loose or watery stools contain visiblered blood. Dysentery is most often caused byShigella species (bacillary dysentery) or Entamoeba histolytica(amoebic dysentery) [3].Kharaa and Orkhon River are tributaries of the Selenge River-basin, in which many mining and other industries,agriculture, and residential areas reside. It has become a one pollutant factor for water of the Kharaa andOrkhon rivers. As a result, water of the Tuul, Kharaa and Orkhon River was reported to be highly contaminated(Mongolian Human Development Report 2010: Water and Development report) [4].GOAL:The aim of the research was to study incidence of gastrointestinal infectious diseases among population ofsoums are located in Selenge River Basin.MATERIALS AND METHODS:Data on health statistics 2009-2013 years of gastrointestinal infectious diseases, including dysentery, diarrhea,hepatitis A virus and others, were collected and analyzed.RESULTS:Incidence of dysentery was registered highly among people who live in Mandal soums in 2009-2013 years. Butincidence of dysentery (per 10 000 population 2.82) among population ofMandal soum lower than the Selengeprovince and National average. Incidence of hepatitis A virus was registered highly among people who livein Orkhon (74.46), Orkhontuul (48.86) soums and it was greater than 1.3-2 times than the Selenge provinceaverage. Incidence of diarrhea was registered highly among people who live in Khushaat soum and it wasgreater than 2.18-3.8 times the than Selenge province averageCONCLUSION:Incidences of diarrhea and hepatitis A virus were registered highly in Orkhon, Orkhotuul and Khushaat soumscompared to other target soums and it was greater than 1.3-3.8 times than the Selenge province average.Especially, these diseases were registered highly among 0-16 aged children.

In recent years, many researches that is related to waterborne diseases, especially diarrhea and water quality, safety, personal sanitation, hygiene have been conducting in developing country. Kharaa and Orkhon river are tributaries of the Selenge river basin and the many industries,agriculture, mining, provinces, soums are located in the near of Selenge river basin. Also Tuul,Kharaa and Orkhon river water is very polluted (Mongolian human Development Report 2010: Water and Development report).The aim of the research is to study correlation between to Kharaa and Orkhon river’s water pollution level and rate of gastrointestinal infectious diseases of people who live in the near of Selenge river basin.We analysed Kharaa and Orkhon river’s water quality and statistical data of gastrointestinal infectious diseases (such as dysentery, diarrhea, hepatitis A virus and others). Then we conducted correlation analysis between to river water pollution level and rate of intestinal infectious diseases. Kharaa and Orkhon river’s water was determined “less polluted” by physical, chemical andorganic indicators. But total number of bacteria was determined highly and Proteus vulgaris,Citrobacter freundi, Enterobacter agglomerans pathogens were detected in these river’s water. There were significant positive correlations between level of nitrit in river water and incidence of dysentery and diarrhea. (r=0.38, p=0.022; r=0.291, p=0.005).

Background: In accordance with the development of a rapid pace of modern medical science, requirements for the scholars and teachers of universities that provide the medical professionals throughout the world increase every year and there is an urging demand for the scholars and teachers to develop themselves continuously. Methods: In order to assess the influence of the cooperation on the teacher’s development, we chose 43 teachers who participated in professional development training of the Yonsei university by using non-probabilistic collection method. Results: 77,19 % of the study participant teachers responded that professional development training greatly influenced to their teaching skills improvement. 19,3 % responded that it was well influenced, and 3.51% responded as slightly influenced. The majority of the participants or 43,86% responded that the professionaly training greatly influenced to their clinical aid and service skill improvement. 36,84% responded as well influenced,12.28 % responded as moderely influenced, 3.51 % responded as slightly influenced and 3.51% responded.The question of how the training influenced for their improvement of scientific research, 3% responded as not influenced at all, 11 % responded as slightly influenced, 30 % respoded as well inflienced and 56% responded as greatly influenced. Conclusion The participants responded to the question on how the training has influenced on professional development training as greatly influenced to their teaching skills improvement. As teachers from the branch universities who participated in the study have a statistical significance. (p=0,04)

BACKGROUND. Uterine cervical cancer is the fourth leading cause of cancer deaths in women worldwide. In our country, cervical cancer is second most common cancer in women. Uterine cervical smear (Papanicolaou test) remains an effective and widely used method for early detection of precancerous and cancerous lesions. Since 2002, the cervical smear was introduced to the clinical practice of our country. However, there is no study to performed external quality assurance of cervical smear until now. MATERIALS AND METHODS. We selected 20 glass slides of uterine cervical smear, the diagnosis was approved by histopathology. Each chosen slides were evaluated by four cytologists of A, B, C, D hospitals with hidden clinical information, independently. RESULTS. The sensitivity of A, B, C and D hospitals were 87.5%, 93.3%, 93.3%, and 93.3%, respectively. The specificity of A, B, C and D hospitals was 85.7%, 85.7%, 75%, and 66.6%, respectively. The diagnostic concordance of A, B, C and D was 70%, 75%, 50%, and 55%, respectively. The agreement of cytological diagnosis was moderate (kappa = 0.55), moderate (kappa = 0.43), fair (kappa = 0.37), and fair (kappa = 0.33) in A, B, C, and D hospitals, respectively. CONCLUSION: The external quality assurance in cytopathology is needed in Mongolia. The diagnostic concordance method would be applicable in our country to improve diagnostic agreement.

BACKGROUND: According to the United Nations, drug reports 2016, 250 million people aged 15 to 64 an estimated 29 million of them have used drugs and narcotics. The United nations states that the drug and narcotic manufacturing have increased by three times in east 15 years. Mongolia is located between Russia and China that are the most drug used countries in the world and it can increase the risk of drug usage in Mongolia. OBJECTIVE: Study to knowledge and attitude about drugs and narcotics among the high school, college and universities students in Ulaanbaatar. METHODS: The research was conducted among the school, college and universities students and the analytic research method was used in our research. 176 middle and high school students, 215 university students and 70 college students from morning classes were participated in the survey. The survey research was used method of collecting information and materials about the drug usage and narcotics. SPSS 17 was used for statistical analysis. RESULTS: The highest point was 16 (n=1) and lowest point was 0 (n=16) and the knowledge of drugs among the students was 8.14. Results releated that 7.8% (n=36) of students have enough information about the drugs and narcotics, 62.9% (n=261) of students did not have enough information and 29.3% (n=135) of them have informed moderately. CONCLUSIONS: Exploring the knowledge about drugs and narcotics among the students, 7.8% of them have enough information, 62.9% of them did not have enough information and 29.3% of them have informed moderately

Background: Stroke is a leading cause of death and disability, especially in low-income and middle-income countries and it impacts a tremendous medical, emotional and fiscal burden on society. Due to advances in Western healthcare, the prevalence of stroke since 1970 has decreased by 42%, whereas it has more than doubled in low-income to middle-income countries.
Stroke is a heterogeneous, multifactorial disease regulated by modifiable and nonmodifiable risk factors. Approximately 80% of stroke events could be prevented by making simple lifestyle modifications. In fact, nationwide characterization of well-known stroke factors in all social backgrounds is essential, however; populations can differ significantly not only in their socio-behavioral, legal, and geographical conditions, but also from other, historically understudied. Therefore, it is crucial to determine characterization of risk factors for ischemic stroke among Mongolian population. Objective: To determine etiology and risk factors for ischemic stroke among Mongolian population Material and methods: Our study was conducted by case-control study design. Cases were patients with acute first stroke; controls were matched with cases, recruited in a 1.2:1 ratio, for age and sex. The case series study was conducted in Stroke center of Third State Central hospital from January 2017 to December 2017. Structured questionnaires were administered and physical examinations were done in the same manner in cases and controls. Self-reported history of hypertension and diabetes mellitus or blood pressure of 140/90 mm Hg and blood sugar 6.4 mmol/L or higher was used to hypertension and diabetes mellitus, respectively. Smoking status was defined as never, former, or current smoker. Alcohol use was categorized into never or former, low intake, moderate intake, and high or episodic heavy intake. Atrial fibrillation was based on previous history, review of baseline electrocardiograph results (for cases and controls). Odds ratios (OR) and logistic regression were calculated, with 95% confidence intervals. Results: In total, 173 patients with ischemic stroke and 146 controls were included. The patients’ age ranged from 17 to 92, the mean age was 61.2. Ischemic stroke more frequent in man than women by 27.4%. Previous history of hypertension or blood pressure of 140/90 mm Hg or higher (OR 2.40, 95% CI 1.48-3.88), diabetes mellitus (OR 3.08, 95% CI 1.44-6.57), hyperlipidemia (OR 5.09, 95% CI 2.64-9.82) atrial fibrillation (OR 8.70, 95% CI 2.01-37.64 ), current smoking (OR 2.07, 95% CI 1.26-3.40), alcohol consumption (OR 4.75, 95% CI 2.58-8.73) were all significantly associated with ischemic stroke. The mean age was lower in patients with stroke of other determined etiology. The frequency of hypertension was higher in patients with lacunar infarct than other subtypes. Smoking was high frequent in patients with large artery atherosclerosis. Conclusion 6 potentially modifiable risk factors were collectively associated with ischemic stroke and were different among ischemic stroke subtypes. The odds ratios of these risk factors are higher than other countries’ study.
