Background: The cornerstone of medical education in training qualified physicians lies in foundational scientific knowledge, which forms the basis for clinical reasoning and diagnostic-therapeutic decision-making. Anatomy constitutes one of the core foundational subjects within the medical doctor training curriculum and exerts a direct influence on the development of students’ baseline knowledge and the formation of their clinical thinking. This study was conducted to evaluate the anatomy curriculum through assessments by first-year students enrolled in the basic medical education program, with the aim of enhancing instructional quality and improving the structure and organization of the course. Aim: To investigate the satisfaction ratings of first-year students in the basic medical education program regarding the Anatomy-1 course. Material and Methods: The study was carried out using an analytical cross-sectional design during the first semester of the 2025–2026 academic year. Data were collected from a total of 289 first-year students of the basic medical education program at the School of Bio-Medicine of MNUMS (Mongolian National University of Medical Sciences) using a questionnaire comprising 24 items in total—3 demographic questions, 20 general satisfaction questions, and 1 open-ended question—with each item rated on a 5-point Likert scale. Data were processed using SPSS 23.0 software, employing descriptive statistics, two-sample t-tests, ANOVA, Pearson’s correlation, and factor analysis. Results: Of the study participants, 14.2% were male and 85.8% were female, with the cohort distributed across programs as follows: TAM 10.38%, TMS 17.30%, MDS 44.29%, PDS 13.15%, and DSS 14.88%. The overall satisfaction level was 4.59±0.66, falling within the “good” range. The highest rating was attributed to “Faculty members possess strong professional knowledge and skills” (DSS, 4.91±0.37), whereas the lowest rating was assigned to “Students’ knowledge and skills are evaluated objectively and fairly” (PDS, 4.16±0.75). The internal consistency coefficient of the questionnaire yielded α=0.909, indicating excellent reliability. Correlation analysis revealed strong positive associations among instructors’ respect for students’ viewpoints (Q4), instructors’ communication and demeanor (Q5), and professional ethics (Q6) (r=0.787; r=0.755; p<0.01). Factor analysis produced a KMO value of 0.865 and a Bartlett’s test result of p=0.000; accordingly, all 20 items were grouped into two factors—”Faculty Professional Competence” and “Learning Environment and Organization”—which collectively accounted for 58.74% of the total variance. Conclusions 1. The findings indicate that the overall satisfaction of first-year basic medical education students who participated in the study was at a favorable level. 2. Faculty professional competence and the learning environment and organization were identified as factors influencing student satisfaction, explaining 58.74% of the total variance in the results. It was further established that adherence to professional ethics, respect for students’ perspectives, and equitable treatment are contingent upon the instructor’s knowledge and professional expertise.

Background: Organizational culture, reflected through institutional values, beliefs, behavioral norms, communication culture, and patterns of collaboration, plays an important role in organizational development. In educational institutions that train health professionals, organizational culture influences not only the internal environment but also the formation of future professionals’ ethics, attitudes, and communication culture. In Mongolia, there is limited research that comprehensively examines organizational culture, institutional values, behavioral norms, and their relationship with satisfaction in higher education institutions. This formed the rationale for the present study. Aim: This study aimed to comparatively assess the perceptions and attitudes of faculty, staff, and students toward organizational culture at the School of Pharmacy, Mongolian National University of Medical Sciences. Materials and Methods: A cross-sectional analytical study design was employed. Data were collected using a structured questionnaire from 194 participants, including faculty, staff, and students of the School of Pharmacy. The data were analyzed using SPSS version 26.0, and a p-value of <0.05 was considered statistically significant. Results: A total of 194 participants were included in the study; 87.6% were students and 12.4% were faculty members. Most participants were female (93.3%), while 6.7% were male. Regarding self-assessed knowledge of organizational culture policy, 47.9% reported having moderate knowledge, 19.6% good knowledge, and 4.6% very good knowledge, whereas 24.2% reported not knowing and 3.6% reported having no knowledge at all. When comparing groups, the mean satisfaction score was 3.73 among faculty and staff, 4.19 among graduate and postgraduate students, and 3.42 among undergraduate students, showing a statistically significant difference (p=0.003). Among undergraduate students, fifth-year students rated organizational culture the highest, with scores of 3.99 for values, 4.14 for behavioral norms, and 3.56 for satisfaction. In contrast, fourth-year students had the lowest scores for behavioral norms (2.88) and satisfaction (2.41), with statistically significant differences (p<0.05). In terms of satisfaction level, 41.2% of participants rated their satisfaction as “Good” and 29.4% as “Very good.” A statistically significant positive association was observed between knowledge of organizational culture policy and satisfaction (p=0.001). Satisfaction was also positively correlated with organizational culture indicators, with the strongest correlations observed for internal environmental culture and comfort (r=0.802), institutional image (r=0.787), and accessibility of information (r=0.760) (p<0.01). Conclusions 1. The perceptions and evaluations of organizational cultural values and behavioral norms among faculty, staff, and students of the School of Pharmacy differed according to their position and level of experience. 2. Participants who demonstrated a higher level of knowledge regarding the institution’s cultural policy reported greater satisfaction, whereas those with limited knowledge showed lower levels of satisfaction.

Background: The Anatomy course, which provides general foundational knowledge on the structure of all organ systems of the human body, is a core professional course in the bachelor’s curricula of Pharmacy, Biomedical Science, Hygiene and Epidemiology, Public Health, Occupational Safety and Health, and Nutrition and Dietetics. Student satisfaction is not only an important indicator of the quality of medical education, but also influences graduates’ knowledge, skills, and attitudes; therefore, continuous research in this area is necessary. Aim: To determine the level of satisfaction with the Anatomy curriculum among first-year students in basic health science programs and to identify factors influencing their satisfaction, with the aim of improving the quality of teaching. Materials and Methods: An analytical cross-sectional study was conducted from September 2025 to February 2026 among 182 first-year students enrolled in the following programs at Mongolian National University of Medical Sciences (MNUMS): Biomedical Research, Pharmacy, Health Epidemiology, Public Health, Health Informatics, and Traditional Medicine Therapy. Student satisfaction with the quality of the Anatomy course was assessed using a 24-item questionnaire. Data were analyzed using SPSS version 26, applying descriptive statistics, independent-samples t-test, one-way analysis of variance (ANOVA), Pearson correlation, factor analysis, and multiple regression analysis. A p-value of <0.05 was considered statistically significant. Results: The internal consistency of the satisfaction scale was very high (Cronbach’s α=0.928). The mean overall satisfaction score of the participants was 4.61±0.67. There was no significant difference in overall satisfaction by gender (p > 0.05). Factor analysis identified two main factors influencing the evaluation of teaching quality (KMO=0.894; Bartlett’s test p<0.001), which together explained 52.73% of the total variance. The first factor was “Teachers’ professional competence, communication, attitude, and assessment,” and the second factor was “Course organization, learning environment, and instructional materials.” Correlation analysis showed that better course organization and higher teacher engagement were positively associated with students’ satisfaction (p<0.01). Conclusions 1. Among first-year basic health science students, satisfaction with the Anatomy course was influenced by teachers’ professional competence, ethics, interpersonal communication, and fair, objective assessment. 2. Adherence to professional ethics and maintaining respectful communication with students were found to be closely related to teachers’ knowledge and professional skills.

Background: The human head is an integrated biological structure composed of the brain, cranial bones, facial structures, neuromuscular systems, and sensory organs, all interconnected through coordinated signaling. The relationship between brain development, function, and craniofacial growth is most evident after birth, during which the head increases approximately fourfold in size before adulthood. Brain morphology and volume are associated not only with neurological disorders but also with cognitive and behavioral characteristics. For example, children with holoprosencephaly often present with varying degrees of facial anomalies, while studies have shown that adolescents with malocclusion exhibit higher levels of anxiety, depression, and psychological stress. With the increasing availability of magnetic resonance imaging (MRI), it has become an essential diagnostic tool in clinical practice. MRI is particularly advantageous in pediatric populations due to the absence of ionizing radiation and its superior soft tissue contrast. Recent advances in image processing techniques have enabled comprehensive analysis of both brain structures and craniofacial morphology from a single MRI dataset, forming the basis of this study. Aim: To investigate the relationship between brain tissue volumes and maxillary hypoplasia using MRI-based voxelbased morphometry in children with neurological conditions. Materials and Methods: This study was conducted at the School of Biomedicine, Mongolian National University of Medical Sciences, in collaboration with Chifeng University, as part of the project titled “Investigation of the relationship between craniofacial anomalies and brain disorders using MRI”, funded by the Ministry of Education and Science. Voxel-based morphometry (VBM) analysis was performed on brain MRI scans of children aged 9–11 years. Results: Among the 25 children included in the study, 17 (68%) were male. The youngest average age was observed in the maxillary hypoplasia group (8.4±0.95 years). The signal-to-noise ratio (SNR) of MRI was lowest in the non-temporal epilepsy group (41.1±1.35) and higher in the maxillary hypoplasia group (49.6±8.22). Both epilepsy and maxillary hypoplasia groups demonstrated physiological asymmetry of the cerebral hemispheres, with left parietal lobe dominance (−0.1% and −0.3 cm, respectively). Right frontal lobe dominance (+1.1%) was observed only in the epilepsy group. Conclusion Children aged 9–11 years with maxillary hypoplasia showed a reduction in both gray and white matter volumes of the brain. These findings highlight the importance of early diagnosis of neurodevelopmental disorders affecting odontogenesis and emphasize the need for a multidisciplinary team-based management approach.

Background: The continuous annual increase in the prevalence of diabetes mellitus (DM) poses significant challenges not only within our nation but also globally in the control and management of tuberculosis. Aim: This study aimed to determine the incidence of pulmonary tuberculosis among individuals with type 2 diabetes mellitus (T2DM) residing in six central districts of Ulaanbaatar and to investigate associated factors. Materials and Methods: A cross-sectional study design was employed. Participants aged 18 years and older diagnosed with T2DM and receiving care at endocrinology clinics in six central districts of Ulaanbaatar were selected using systematic random sampling. Presumptive TB cases were identified through a structured questionnaire and chest X-ray. Sputum specimens were collected and subjected to smear microscopy and Xpert MTB/RIF assay for tuberculosis detection. Cases confirmed by laboratory diagnosis, currently undergoing tuberculosis treatment and previously treated cases as per questionnaire data were classified as tuberculosis cases, and prevalence was calculated. Results: A total of 1,644 individuals with T2DM were enrolled in the study, of whom 836 (50.9%) were female, with a mean age of 58 years (range 19–89). The overall prevalence of presumptive TB cases was 10.5% (n=172; 95% CI, 9.0–12.0). Among 112 suspected cases from whom sputum samples were obtained, 10 (8.9%; 95% CI, 4.9–15.7) were laboratory-confirmed for M.tuberculosis. Notably, 7.2% (6 cases; 95% CI, 3.4–14.9) of asymptomatic individuals with abnormal X-ray findings were diagnosed with tuberculosis. According to questionnaire responses, 9 participants (0.5%; 95% CI, 0.3–1.0) were undergoing tuberculosis treatment, and 53 (3.2%; 95% CI, 2.5–4.2) reported a previously treated TB cases. The overall prevalence of tuberculosis among individuals with diabetes was 4.4% (n=72; 95% CI, 3.5–5.5). Stratification by age and sex revealed a significantly higher prevalence among males (5.9%; n=48; 95% CI, 4.5–7.8) compared to females (2.9%; 95% CI, 1.2–4.2) (p=0.002), indicating a twofold increased risk of tuberculosis in males. Although no statistically significant differences in tuberculosis prevalence were observed across age groups (p>0.05), a declining trend in prevalence with older age was noted. Conclusion The prevalence of tuberculosis among individuals with type 2 diabetes was 4.4% (n=72; 95% CI, 3.5–5.5), with a significantly higher rate in males (p=0.002) and a decreasing trend with increasing age. Among asymptomatic individuals exhibiting radiographic abnormalities, 7.2% were confirmed to have tuberculosis via laboratory testing

Background: Pregnancy induces multiple physiological, metabolic, and immunological alterations that increase susceptibility to infections, often necessitating antibiotic therapy. Evaluating the rational use of antibiotics among pregnant women is crucial for optimizing antimicrobial stewardship at the hospital level, improving clinical pharmacy services, and reducing the risk of antimicrobial resistance. Aim: To assess the rational use of antibiotics, including indication, selection, dosage, and treatment duration—among hospitalized pregnant women in the Department of High-Risk Pregnancy and the Department of Preterm Birth at the National Center for Maternal and Child Health. Materials and Methods: A retrospective study was conducted using a specifically designed data collection form to assess antibiotic use among inpatients at the National Center for Maternal and Child Health. Descriptive statistical analyses were performed using SPSS version 29.0. Results: A total of 348 pregnant inpatients were included, with a mean age of 31.6 ± 6.9 years. The mean length of hospital stay was significantly longer in the Department of Preterm Birth (12.5 ± 5.0 days) compared to the Department of High-Risk Pregnancy (5.9 ± 2.0 days; p < 0.001). The indications for antibiotic use were therapeutic in 39.1%, prophylactic in 33.0%, and unspecified in 21.3% of cases. The most frequently prescribed antibiotic regimen was a combination of β-lactams and metronidazole (29%). While the dosing of cefazolin and cefotaxime was largely appropriate, notable dosing discrepancies were observed in the dosing of ampicillin and azithromycin. Based on the U.S. FDA pregnancy risk classification, among a total of 762 antibiotic prescriptions, 87.0% belonged to category B, 8.8% to category C, and 4.2% to category D, with no significant variation across trimesters (p = 0.695). Conclusion The assessment of antibiotic use among hospitalized pregnant women at the National Center for Maternal and Child Health revealed that 39.1% of the prescriptions were therapeutic, 33.0% were prophylactic, and 21.3% lacked a clear indication for use. β-lactam antibiotics were the most commonly used agents, frequently combined with metronidazole. Based on the FDA classification system, 87% of the prescribed antibiotics belonged to category B, 8.8% to category C, and 4.2% to category D. These findings indicate inappropriate antibiotic use and insufficient implementation of antimicrobial susceptibility testing. Therefore, strict adherence to antibiotic stewardship programs and strengthening of clinical pharmacy services are necessary to improve antibiotic use practices.

Background: Studying the human embryonic and fetal organ systems development patterns and determining their quantitative indicators is of scientific and practical importance in medicine and health in every nation.
Distortions and pathologies during the development of the embryo are the causes of congenital disabilities. Among the congenital malformations, facial malformations are the 3rd place, including cleft lip and palate in 70% and Srouzon's syndrome in 30%. In addition, abnormalities due to changes in the size, shape, and position of the jaw are also mentioned in the 2021.04.21 issue of Morphology magazine in the study "Morphometric parameters of the bones of the skull and face during the development of newborns and fetuses". In our country, Ariuntuul G (2005) determined that cleft lip and cleft palate occur at 0.76/1000 or 1 in 1314 live births, while Ayanga G (2012) found that it occurs at 1 in 1072 live births or 0.93/1000. Moreover, the eye cup dimensions of Mongolian fetuses aged 16 36 weeks have a positive linear relationship with the gestational age determined using ultrasound by Nandintsetseg B (2015) et al. Compared with the other countries, the eyecup is slightly wider, and the outer edge distance is similar, whereas the inner edge distance is shorter. Purpose: To summarize research work and determine the embryonic development of bones involved in the formation of the face and facial parts, the period of bone formation, the point of ossification, and the period of formation. Methods: During fetal development, human organ systems grow and develop at different rates but in a particular relationship. This feature of growth and development is also clearly observed in the structure of the head and facial bones, and the results of researchers who have studied this aspect are selected in the articles. Results: Embryonic and fetal development of bone are clinically significant not only from the point of view of its morphogenesis but also from the point of view of congenital disabilities. Conclusion In the analysis of the sources, most of the works on the prenatal period of the development of the same body have studied the development of specific structures of the face and facial area, such as the palatine bones and nasal bones, or have generally covered the development of particular systems in the embryo and fetus, and face, there are relatively few works that show the entire dynamics of growth and development of facial bones.

Introduction: The department of Maxillofacial surgery of the National Center for Maternal and Child Health (NCMCH) has a nationwide tertiary medical service for the children who is with congenital orofacial anomalies, facial injury, nonmalignant tumors of this area, and inflammations of maxillofacial area following odontogenic infection and other reasons as well. For the last years the number of the patients who are with odontogenic inflammation on the department has been growing constantly meaning that the necessity of medical care for our countries for children is also growing. Therefore by studying and analyzing the structure of the odontogenic inflammation and to determine the most frequent odontogenic inflammation among children in our country, to prevent them, define the treatment plan. Aim: To clarify what kind of odontogenic maxillofacial inflammatory diseases mainly occurs among Mongolian children. Materials and Method: We included all patients who are with odontogenic inflammation and underwent emergency and planned surgery in the department of Maxillofacial surgery, NCMCH between 2014-2018.
We used descriptive method based on the information of inpatients history record between 2014.01.01- 2018.12.31 at the department of Maxillofacial surgery, NCMCH and using our own –designed, prescreened survey card.
Statistical data processing is done using Microsoft Office-2019, SPSS for windows and STATA programs, and the results are shown illustrated method. The survey identified the incidence and frequency of each disease classification, and analyzed the characteristics of the child’s age, sex, and residency. Result : In total 3533 children with odontogenic inflammation, whom age range is 0-18 years old, admitted at the department of Maxillofacial surgery for the surgical treatment were involved in this study.
Among which 1452(41.1%) male, 2081(58.9%) female. Considering the residency 2918(82.5%) children from Ulan-Bator and 615 (17.5%) children from countryside. The most of patients, who involved in this study were with odontogenic periostitis of maxillofacial area (67.5%), most were girls and preschool age (3-5 ages). Conclusion Based on the result of our study the most frequent inflammation was odontogenic periostitis of maxilla and mandible bone with 67.5%. The odontogenic phlegmon of orofacial area was the 2nd most frequent with 25.1%.
Inflammation of maxillofacial area was most frequent in 3-5 age group (preschool age) with 41.4%, and mostly in male. Considering the residency with 82.5% highest in Ulanbator.

Introduction: Studies demonstrated that the apolipoprotein B/apolipoprotein A-I (Apo B/apo A-I) ratio predicts cardiovascular risk better than any of the cholesterol indexes. Apo B and Apo A-1 are assumed to be superiormarkers for lipoprotein abnormalities [1,2]. The concentrations of Apo B and Apo A-1 are associated with cardiovascular disease more strongly than the corresponding lipoprotein cholesterol fractions, the discriminant value of these apoproteins in absolute terms appears to be less important than of their ratio (the Apo B/Apo A-1 ratio) [3, 5-7]. The Apo B/Apo A-1 ratio reflects the balance of atherogenic and antiatherogenic lipoproteins in plasma [4]. Multiple clinical and epidemiological studies have confirmed that the Apo B/Apo A-1 ratio is a superior marker for cardiovascular disease compared with lipids and lipoproteins or their ratios [8, 9]. Goal: We determined the variation limits of the Apo B/Apo A-1 ratio in healthy participants with normolipidemia and the relationship of this ratio with other lipid parameters. Material and Methods: A total of 146 normolipidemic healthy participants aged 25–60 years were included in the study. Anthropometric measurements (height and weight) and other personal information were obtained during the clinical examination and the interview. Participants were included in the study using the following criteria:
1. body mass index < 30 kg/m2;

2. TC < 5.2mmol/L;
3. triglycerides (TG) ≤1.7 mmol/L;
4. HDL-C ≥1.03 mmol/L ( woman), ≥ 1.29 mmol/L (male) .
The plasma levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), apo A-I, Apo B and Apo B/Apo A-1 were determined after a 12 h fasting period. The non-HDL-C was calculated as the difference between the TC and HDL-C. Most research data emphasized that the values for the Apo B/Apo A-1 ratio that define a high cardiovascular risk were proposed to be 0.9 for men and 0.8 for women. Statistical Analysis. The statistical analysis was performed using SPSS 21.0 (USA). Differences between the groups were analyzed using the Mann-Whitney test and the chi-squared test. Correlations between the indices were assessed using the Spearman’s rank correlation. A value of < 0.05 was accepted as statistically significant. Results: The relationship of ratio of apolipoprotein (Apo) B/Apo A-1 with other indicators of lipid metabolism in healthy people with normal lipidemia was analyzed. The Apo B/Apo A-1 ratio in the studied normolipidemic subjects was 0.69 ± 0.17. The percentage of subjects with the Apo B/Apo A-1 ratio exceeding 0.9 (the accepted risk value of cardiovascular disease) was 36.3 %.The subjects with Apo B/Apo A-1>0.9 were characterized by higher HDL-C levels and atherogenic Aпo B, Apo B/Apo A-1 but lower values Apo A-1. Conclusion The subjects with normolipidemia the unfavorable Apo B/Apo A-I ratio> 0.9 had more atherogenic lipid profile.

Introduction: Cardiovascular Disease (CVD) is a major cause of morbidity and a leading contributor to mortality in both developed and developing countries. With rapid socioeconomic development, CVD has reached epidemic proportions in developing countries in recent decades. Dyslipidemia, elevated level of plasma cholesterol, together with arterial hipertension, is the main modifiable risk factor atherosclerosis and cardiovascular diseases (CVD) development. Surveys to monitor and measure dyslipidemia burden in a Mongolian population has not been conducted in recent years and the available data on the prevalence, types, and associated factors of dyslipidemia in the general population is relatively insufficient and outdated. Monitoring of lipid profile at populational level is an important instrument of prevention medicine, applied for CVD populational risk assessment. Goal: Evaluate comparisons of adult blood lipid levels in age, gender and location. Material and Methods: In this study, 500 people aged 25-65 were classified into age groups (47.1% for males and 52.9% for females). Blood plasma in total cholesterol (TC), triglyceride (TG), high density (HDL-C) and low density (LDL-C) lipoprotein-cholesterol, apolipoprotein - ApoA1, Apo B and ratio of ApoB / ApoA1 were estimated. Statistical analysis was performed using SPSS 22.0 Results: Mean age of the participants was 48.8±14.2 years old. Mean values for male TC-4.85±0.92 mmol/l, TG-1.58±1.19 mmol/l, LDL-C-3.24±0.98 mmol/l, HLD-C-1.62±0.21, for women- 4.47±0.96 mmol/l, 1.22±0.47 mmol/l, 2.95±1.01 mmol/l, 1.77±0.23 mmol/l respectively. The mean blood TC,TG levels tended to increase with age group in male compared to women. The prevalence of an increased blood LDL-C levels or risks for an increased blood LDL-C was statistically significantly high in male. Conclusion The prevalence of lipid was shown as high, that demands respective prevention and management.
