BACKGROUNDAir pollution issue has become the largest problem of Ulaanbaatar city in the last decade affecting health and wellbeing of its citizens. Air pollution levels are increasing considerably in winter as a result of coal burning by city dwellers living in ger areas. Our study purpose was to survey the impact of air pollution on infant health of Ulaanbaatar city in 2012.METHODSData of 7484 on births at Khan-Uul and Sukhbaatar districts residence mothers and infants of Ulaanbaatar city from 2012 and corresponding daily air pollution level data (CO, NO2, SO2 and PM10) from the Ulaanbaatar city air quality monitoring stations were used.RESULTSAir pollution levels in Ulaanbaatar city significantly affect birth outcomes. Exposure to high levels of СО2 of during the third trimester of pregnancy reduces newborn’s weight. Exposure to NO2 is not influencing to newborn’s weight. Mothers who lived in more polluted area during pregnancy period more likely had baby reduced weight in 44 grams.

Background:In the scope of the “School Lunch” program initiated by the Government of Mongolia, pupils of primary schools are served with meals prepared in school canteens and food products provided by food manufacturers. The safety of the provided food products must be monitored and evaluated. The purpose of our study was to evaluate the safety of the meals and food products being given to pupils in the frame of the above program.Materials and methods:Nutritious values and safety of 31 samples of school canteen meals and food products of 5 general education schools were determined using microbiological analysis methods based on Mongolian national standards. Results:The analysis results revealed that the total number of microbes in canteen meals fluctuated between 1х102 and 4х102, and no pathogens were detected in the analyzed samples. The quality of all pastry products met the Mongolian standard hygiene requirements. The variation of the total number of microbes in dairy products was 2х105 -4х105, and no pathogens were found in dairy products.Conclusion:Microbiological analyses show that the food products supplied by the contractual companies in the frame of “Lunch” program and meals from the school canteens meet Mongolian hygiene requirements.

Background: In the network of health sector reform, improving the quality and safety of service, organizational development, and ethics and responsibility of doctors and health professionals is a priority issue. Therefore, it is important to study the satisfaction and needs of healthcare workers, who have essential role in the quality and accessibility of health care service, as well as in social and economic development. Materials and methods: This study was carried out using a cross-sectional study design with quantitative method. The questionnaires were conducted from 63 people who were working in the general hospital of Selenge province. To collect data and materials of the study, we used questionnaires from Appendix No.1 of Order 13 of the Minister of Health dated 13 January, 2014. Results: The Satisfaction score of doctors and healthcare workers which was evaluated by themselves was generally 1.74 ± 0.47 or average, meanwhile 1.62 ± 0.41 or good for each group. Conclusion The employee satisfaction with the General Hospital of Selenge aimag is good. The satisfaction of doctors and healthcare workers is not dependent on the age group, gender, position, and seniority.

Background: In the network of health sector reform, improving the quality and safety of service, organizational development, and ethics and responsibility of doctors and health professionals is a priority issue. To bring this, the patient satisfaction is an important matter. Materials and methods: This study was carried out using a cross-sectional study design with quantitative and qualitative method. To collect data and materials of the study, we used questionnaires from Appendix No.2 of Order 13 of the Minister of Health dated 13 January, 2014. Results: 84 (61.8%) of inpatients evaluated hospital care as a good, while 117 of 197 outpatients (59.4%) evaluated hospital care as an average. The general satisfaction of patients is good for inpatients and average for outpatients. Discussion The patient satisfaction was different depending on the department, gender, age and age group for inpatients, while satisfaction was not dependent on age group for outpatients.

Background: Vitamins are nutrients essential for human health. They act as coenzymes that help trigger important chemical reactions necessary for energy production. Reference values for vitamins help physicians evaluate the health status of patients and make clinical decisions. The aim of this study was to determine the mean values and reference intervals for some water-soluble vitamins of Mongolian adults. Materials and Methods: Three hundred and forty healthy adults (170 males and 170 females) of 17 to 69 years of age were selected for the study based on CLSI C28-P3 criteria Defining, establishing & Verifying reference interval in the clinical laboratory; Proposed Guidelines. The study was approved by the Resolution No.76 of 2018 of the Medical Ethics Review Committee of the Ministry of Health. Informed consents were taken from the selected individuals. Morning blood samples of the participants were collected under aseptic conditions. Levels of vitamins B₆, B₉, B₁₂ and vitamin C were measured using a high performance liquid chromatography method. The lower- and upper reference limits were defined as the 2.5th and 97.5th percentiles, respectively. The data were analyzed using SPSS and Excel programs. Results: The mean blood level of vitamin C was 11.88 mg/L (95% CI 10.47-13.29) for men and 9.62 mg/L (95% CI 8.11-11.13) for women. The calculated reference interval for males was 1.40-19.40 mg/L and 1.17-18.04 mg/L for females. The mean concentration of vitamin B₁₂ in the blood of males was 938.45 ng/L (95% CI 747.22-1129.68) and that of females was 864.03 ng/L (95% CI 603.81-1124.25). The reference interval for vitamin B₁₂ was 233.03-1597.00 ng/L in men and 132.45-1623.86 ng/L in women. The mean level of vitamin B₉ was 8.47 ng/mL (95% CI 5.64-11.30) for men and 6.91 ng/mL (95% CI 4.89-8.93) for women. The calculated reference interval for this vitamin in males was 1.04-24.74 ng/mL and that in females was 1.04-21.46 ng/mL. As for vitamin B₆, the mean concentration for men was 44.42 ng/mL (95% CI 37.01-51.83) and for women was 34.67 ng/mL (95% CI 29.97-39.39) with the reference intervals of 5.90-79.02 ng/mL for men and 5.27-61.72 ng/mL for women. Conclusion The reference values for vitamins B₆, B₉, B₁₂ and vitamin C of Mongolian adults do not differ significantly from those observed in other populations. The calculated reference intervals can be used in the practice of health laboratories.

Introduction: Coronavirus infection 2019 (Ковид-19) is an infection caused by a novel virus and induces severe ARDS. КОВИД-19 pandemic has rapidly spreaded in 221 countries, 245,373,039 cases and 4,979,421 mortalities have been reported. Pulmonary and renal thrombotic angiopathy occur in patients with complications of ARDS, sepsis, and multi-organ failure. Elevated D-dimer in КОВИД-19 patients has been reported firstly by doctors in Wuhan, China. In addition, many studies have revealed that elevated D-dimer has been associated with the severity of the diseases, an increased rate of poor prognosis. Objective: We aim to determine D-dimer in КОВИД-19 patients, and patient condition a decrease of D-dimer level after administration of anticoagulant therapy. Case report: We introduce a rare case of КОВИД-19. Laboratory test results and the effect of anticoagulant therapy have been evaluated during the infection. 85 aged women were admitted with a diagnosis other than КОВИД-19. PCR for SARS-Cov-2 was negative on the previous day of admission, and Sars-Cov-2 Ag rapid test was also negative on the admission day. However, the D-dimer test result was much higher with 7120 ng/мл and X-ray and CT revealed a similar pattern to the КОВИД-19 patient. Then anti-Sars-Cov-2 test was positive with 4,08 COI. Based on laboratory test results of D-dimer, LDH, CRP, and CT pattern the patient was diagnosed with post-КОВИД-19 pneumonia, and anticoagulant therapy was initiated additionally to prevent hypercoagulation induced by КОВИД-19. D-dimer test taken before administration of anticoagulant therapy increased more to 10910 ng/мл. 3 days later D-dimer level decreased to 8180ng/мл and the patient’s condition was improved. Conclusion The evaluation of D-dimer of the patients with КОВИД-19 is highly significant. Anticoagulant therapy might be necessary for КОВИД-19 patients with high D-dimer level in serum. Further studies are needed to assess the long-term outcome of the illness and mortality.
