Background: Respiratory diseases remain among the top five leading causes of morbidity, with an incidence rate of 788.4 cases per 10,000 population in 2021. Among these, acute bronchitis accounts for 9.3%. According to international clinical guidelines for the diagnosis and treatment of adult acute bronchitis, symptoms usually resolve spontaneously within 1–3 weeks, but they considerably reduce the patient’s quality of life. Therefore, Colsaurin syrup, a new natural formulation with analgesic and anti-inflammatory effects, was clinically investigated to assess its efficacy and safety. The introduction of this domestically produced herbal medicine into clinical practice is expected to have both medical and socioeconomic significance by expanding the range of national pharmaceutical products. Aim: To evaluate the effect of Colsaurin syrup on the quality of life in adults diagnosed with acute bronchitis. Materials and Methods: This study was a randomized, double-blind, placebo-controlled clinical trial conducted among inpatients at Songinokhairkhan District General Hospital, Ulaanbaatar. Adult patients diagnosed with acute bronchitis (J20) who met the inclusion criteria and provided informed consent were enrolled. Participants were randomly assigned to either the Colsaurin or placebo group. Result: In the Bronchitis Severity Score (BBS) assessment, baseline mean scores indicated severe disease: 10.88±2.47 in the Colsaurin group and 10.67±2.16 in the placebo group. After treatment, scores decreased significantly to 3.50±1.41 (p<0.001) in the Colsaurin group and 5.00±2.24 (p=0.006) in the placebo group, indicating greater improvement in the Colsaurin-treated patients. In the Visual Analog Scale (VAS) assessment, the mean pre-treatment score for both groups was 7, corresponding to frequent cough, which decreased to 2 after treatment (p<0.05), representing a 28% reduction in coughing discomfort. In the Cough and Sputum Assessment Questionnaire (CASA-Q), the Colsaurin group showed a 3.25-point reduction after treatment, indicating a significant decrease in cough frequency and triggering factors (p<0.05). Conclusion 1. In patients diagnosed with acute bronchitis (J20), treatment with Colsaurin syrup reduced disease severity by 30% and alleviated cough-related discomfort by 28% compared to baseline. 2. Moreover, patients reported improved sleep quality and work capacity, reflecting an overall enhancement in quality of life. 3. No adverse effects were observed in the Colsaurin treatment group.

Background: Stress, insomnia, and anxiety are among the most prevalent mental health disorders in society and are associated with negative consequences such as reduced work capacity, decreased quality of life, and an increased risk of chronic diseases worldwide. During stress, the sympathetic nervous system becomes activated, leading to physiological changes such as increased heart rate, vasoconstriction, and elevated arterial blood pressure. If prolonged, these changes may increase the risk of developing hypertension and cardiovascular diseases. In recent years, pharmacological research on medicinal plants with sedative, hypnotic, and anxiolytic effects has been intensively conducted. Therefore, there is a growing need to develop a combined herbal preparation from Valeriana officinalis L. and Leonurus sibiricus L., which have been used in traditional medicine for sedative, hypnotic, and anxiolytic effects, and to investigate their effects on arterial blood pressure. Aim: To investigate the effect of an herbal complex preparation on arterial blood pressure. Materials and Methods: An herbal complex preparation was formulated from 70% ethanol extracts of Valeriana officinalis L. and Leonurus sibiricus L. in a 30:70 ratio. Its effects on normal blood pressure and Angiotensin II-induced hypertension were evaluated in C57BL/6 mice. The preparation was administered orally at doses of 750 and 1000 mg/kg. Systolic and diastolic blood pressure were measured using a Softron BP-98AWU system and compared between groups. Results: At doses of 750 and 1000 mg/kg, the complex preparation reduced systolic blood pressure (SBP) by 6.4-12.0% and diastolic blood pressure (DBP) by 16.1-28.1% under normal conditions (p<0.05). In the intraperitoneal Angiotensin II-induced hypertension model, SBP decreased by 5.9-19.6% and DBP by 6.3-20.1% (p<0.05). In the osmotic pump-induced Angiotensin II hypertension model, the 750 mg/kg dose reduced SBP by 18.2-33% and DBP by 17.2-28.3% (p<0.001). Conclusion The herbal complex preparation at doses of 750 and 1000 mg/kg demonstrated a significant antihypertensive effect in both normal and Angiotensin II-induced hypertensive mice.

Introduction: According to the World Health Organization (WHO) data from 2022, 19.9 million people were diagnosed with cancer globally, and 9.7 million people died from the disease. In recent years, the incidence of colorectal cancer (CRC) has been rapidly increasing, ranking 4th among all cancers with 18.4 cases and 8.1 deaths per 100,000 population. In Mongolia, 826 new cases of CRC have been registered over the past six years, with an incidence rate of 8.2 cases and a mortality rate of 5.03 per 100,000 population. It is projected that by 2030, the incidence will reach 13.28 cases and the mortality rate will rise to 8.72 per 100,000 population. We aimed to comprehensively examine the risk factors for colorectal cancer among the population of Mongolia, establish a scientific basis for early detection and prevention, and strengthen preventive measures. Materials and Methods: A case-control study was conducted from 2022 to 2024. The study enrolled a total of 305 subjects, including 98 patients with colorectal cancer, 101 patients with colon polyps, and 106 healthy subjects. The risk. questionnaire consisted of 50 questions divided into 10 sections. All statistical analysis was performed with SPSS version 23.0 software (SPSS Inc., Chicago, IL, USA) and P value <0.05 was considered statistically significant. categorical data was represented as numbers and percentages. Pearson’s chi-squared and Fisher’s exact test were used to compare categorical variables. Multivariate logistic regression was used to identify the risk factor associated with recurrence. The study protocol was approved by Ethics Review Committee of Ministry of Health of Mongolia on 17 March 2023 (approval number: 23/012). Results: The average age of the participants was 57.1±12.8 years. Among all study participants, 37.6% (115) were male and 62.4% (188) were female. Comparison of colorectal cancer incidence by age and gender revealed no statistically significant differences (p=0.021; p=0.422). Regular physical exercise was found to have a protective effect against colorectal cancer (p=0.076; OR 0.341 95% Cl 0.118-.0986). The frequency of fruit consumption, 4 to 6 times per week (p=0.008, OR 0.08, 95% Cl 0.01-0.45), frequency of vegetable consumption 4 to 6 times per week (p<0.00; OR 0.07, 95% Cl 0.02-0.19), no dining out (0.007, OR 0.3, 95% Cl 0.18-0.68), and meat consumption (p=0.001) are decreased risk of colorectal cancer. Conclusion The patient's age and the presence of colon polyps are risk factors for colorectal cancer, while regular physical activity and a diet rich in fruits and vegetables are protective factors that help reduce the risk of developing colorectal cancer.

Background: The development of accurate and non-invasive diagnostic tools is essential for improving early detection of cancers. Recent studies have shown that serum biomarkers may be useful for early detection of gastric cancer. Aim: We aimed to evaluate the diagnostic accuracy of PGI and PGR biomarkers for detection of the gastric cancer and atrophic gastritis. Materials and Methods: To identify relevant studies, the MEDLINE (PubMed) database was searched using the keywords (((“Gastritis, Atrophic”[Mesh]) OR “Stomach Neoplasms”[Mesh]) AND “Pepsinogen A”[Mesh]) AND “Sensitivity and Specificity”[Mesh]). Based on the inclusion and exclusion criterias, studies were selected according to the PRISMA guidelines. Meta-analysis was performed using Review Manager 5.4.1 and STATA/IC 15.0 (StataCorp LLC, USA, 2017). Results: According to the PRISMA guidelines, we selected a total of 18 studies in this meta-analysis. The meta-analysis results showed that the sensitivity of the PGI for the detection of atrophic gastritis was 58.5% (95% CI, 44.5-71.3), specificity was 90.2% (95% CI, 68.4-97.5), and DOR was 13.0 (95% CI, 2.6-64.6); the sensitivity of the PGR was 69.9% (95% CI, 58.1-79.5), specificity was 80.9% (95% CI, 52.4-94.2), and DOR was 9.8 (95% CI, 2.6-36.9). However, the sensitivity of the PGI biomarkers for detecting gastric cancer was 72.6% (95% CI, 54.7-85.3), specificity was 66.9% (95% CI, 52.5-78.7), DOR was 5.4 (95% CI, 3.1-9.3); PGR sensitivity was 77.8% (95% CI, 64.4-87.4), specificity was 65.0% (95% CI, 53.2-75.1), DOR was 6.6 (95% CI, 3.7-11.7); PGI+PGR sensitivity was 62.3% (95% CI, 51.1-72.2), specificity was 87.6% (95% CI, 78.0-93.3), DOR was 11.6 (95% CI, 6.8-19.8). Conclusion PGI and PGR tests demonstrated high specificity but moderate sensitivity. Although serum pepsinogen cannot replace endoscopy, it is considered to be an additional test and can be used to select high-risk populations.

Introduction: Hepatitis C virus (HCV) infection has both hepatic and extrahepatic manifestations, and it is one of the leading cause of liver transplantation. There’s limited research on extrahepatic symptoms of chronic HCV in Mongolia, thus we aimed to investigate the relationship between cryoglobulinemia and it’s related factors. Methods: The study included 200 participants with active HCV, collecting blood samples for various tests (biochemical analysis, kidney function, and cryoglobulinemia detection). The degree of liver fibrosis was assessed using APRI and FIB4 scores, and the study evaluated other health conditions through a questionnaire. Statistical analysis was performed using SPSS-26. Results: Out of 200 participants, 148 checked for cryoglobulin precipitation and 89 (60.1%) were positive. There was a statistically significant age difference between those with and without cryoglobulinemia (54.62 vs. 50.44 years). A higher percentage of participants with cryoglobulinemia had significant liver fibrosis (10.8% vs. 4.7% without). Liver fibrosis scores tended to increase with age, especially in men. Conclusion Liver fibrosis scores above 3.25 are associated with older age, lower platelet counts, elevated AST and ALT levels, and the presence of cryoglobulinemia. FIB4 scores were higher in men with active HCV and cryoglobulinemia.

Introduction: The worldwide prevalence of obesity and its metabolic complications have increased substantially in recent decades. According to the World Health Organization (WHO) indicate that in 2016, over 1.9 billion adults were overweight and, of these, over 650 million were obese. Obesity is a major risk factor for heart disease, type 2 diabetes, steatotic liver, chronic liver disease, stroke, and some cancers. The global prevalence of obesity and its associated comorbidities continue to increase on a pandemic scale. Aim: To determine metabolic changes in overweight and obese adults and their related diseases based on some parameters of anthropometric and laboratory tests. Materials and Methods: This study was conducted with a case-control design in 2023–2024. There were 150 participants in the study, 50 in the control group with normal weight, 50 in the overweight (BMI<29.9kg/m2) case group, and 50 in the obesity (BMI>30kg/m²) case group. Subjects of three groups were matched by age (±1) and sex. We estimated anthropometric parameters and biochemical laboratory analysis including glucose, lipid, ferrum, and liver parameters. CBC All statistical analysis was performed using SPSS 23 software. Categorical variables were described by numbers and percentages, and the numerical variables were characterized by the median (min and max) for the normal distribution, and mean± standard deviation for the non-normal distribution. The statistical tests utilized were the Chi-square, Fisher’s exact, student t-test, and Mann–Whitney tests. Ethical approval for the survey was obtained from the Medical Ethics Committee under the Ministry of Health Of Mongolia in January 2023. Results: The participants' average age was 46.73±11.45, with 60% being women (90) and 40% being men (60). The prevalence of central obesity and fat % were 52.3% and 37.2%, respectively. Between study groups, there were significant differences in fat% (p=0.004), central obesity (p<0.001), FBG (p=0.024), cholesterin (p=0.017), LDL (p=0.018), HDL (p=0.003), ferrum (p=0.010), АЛАТ (p=0.020), and GGT (p<0.001). Conclusion In overweight and obesity groups, the body fat, fasting blood glucose, cholesterol, LDL, and ALT levels are increased. These changes often lead to conditions like type 2 diabetes, arterial hypertension, steatotic liver disease, and liver fibrosis. Therefore, it is important to develop plans for prevention, early detection, public awareness, and intervention programs targeting obesity in the general population.

Introduction: Cases of gastric cancer have been declining worldwide in recent years. However, gastric cancer incidence increased in the last decade in Mongolia. In Mongolia, over 80% of gastric cancer cases are diagnosed during the late stage. Several studies have revealed that serum pepsinogens (PGs) level reflects, indirectly, histological and functional characteristics of the gastric mucosa. Goal: We aimed to evaluate the risk of gastric cancer and its precancerous condition based on serum PGI, PGI/II biomarkers. Materials and Methods: This case-control study enrolled 114 subjects, including patients with gastric cancer (n=36), atrophic gastritis (n=40) and healthy controls (n=138). The questionnaires were obtained to determine risk factors. Serum PGI, PGII, and H. pylori IgG levels were measured by ELISA (Pepsinogen I ELISA; Pepsinogen II ELISA; H.Pylori IgG ELISA; BIOHIT Plc, Helsinki, Finland). PGI to PGII ratio was calculated. Patients were classified into the ABC(D) group according to Miki K approach. Also, we developed new scoring system based on some risk factors and serum PGI, PGI/II ratio. Logistic regressions were performed to evaluate risk and expressed by odds ratio (OR) and 95% confidence intervals (95%CI). Results: Mean age of the subjects was 60±10.9 years. H.Pylori was positive in 67 subjects. The serum PGI and PGI/II ratio levels were significantly decreased in gastric cancer and atrophic gastritis groups compared to the healthy control. According to classification ABC(D), group D (OR 5.04, 95% CI 1.13-22.50) had higher proportion of atrophic gastritis cases, group C (OR 6.19, 95% CI 1.04-36.78) had higher proportion of gastric cancer cases than others. Additionally, we created a risk prediction scoring system with a score ranging from 0 to 7, based on variables age, family history of gastric cancer, prior disease history, PGI and PGI/II ratio levels. For the atrophic gastritis patients, 17 (42.5%) were classified into medium-risk category (OR 4.49, 95% CI 1.38-14.58) and 17 (42.5%) were classified into high-risk category (OR 7.69, 95% CI 2.16-27.43). Whereas, 11 (30.6%) patients with gastric cancer were classified into medium-risk category (OR 4.35, 95% CI 1.13-16.85), 21 (58.3%) were classified into high-risk category (OR 14.25, 95% CI 3.60-56.43). Conclusion The methods based on serum PGI and PGI/II may identify a high risk population of gastric cancer and atrophic gastritis.

Description: Asymptomatic bacteriuria is defined as the presence of 1x105 or more bacteria per milliliter of urine, although there are no signs of UTI [1]. Asymptomatic bacteriuria is quite common and occurs in 1-5% of healthy women before menopause. The incidence of asymptomatic bacteriuria increases in the elderly (men and women) to 4-19%. Asymptomatic bacteriuria is observed in 0.7% -27% of patients with diabetes mellitus, in 2-10% of pregnant women and in 23-89% of patients with spinal cord injury. Asymptomatic bacteriuria is rarely observed in young men and always requires differential diagnosis with chronic bacterial prostatitis[2].
Among the elderly, those in institutionalized settings such as long-term care facilities and hospitals have a higher prevalence of asymptomatic bacteriuria than those living in the community. Therefore, interest in asymptomatic bacteriuria has shifted from the general population to these groups of individuals. The prevalence varies from 2% to 10% in pregnancy and from 15% to 50% in the elderly in long-term care facilities.[3,4]
This study was undertaken to determine the prevalence of people asymptomatic bacteriuria in among hospitalized people. Purpose: Investigate cases of asymptomatic bacteriuria among hospitalized individuals and determine antibiotic susceptibility by type of pathogen detected in urine. Materials and methods: This cross-sectional study in the “I” Hospital of UB city, Mongolia. We conducted into the study 133 patients. After obtaining informed consent, a midstream clean-catch urine sample was collected in the same 24 hour time window and was evaluated for urinalysis using a dipstick test and routine culture. A positive urine culture was defined as a single urine sample with microbal growth of >10⁵ colony- forming units of a single organism. We use 5-10% Blood agar, UTI agar, Mackkong agar and Chroma agar for a bacterial growth. Then we did antibiotic susceptibility of the determined pathogen. Result: The average age of the respondents was 55.9±14.6, the youngest was 17 years old and the oldest was 91 years old (CI 95% 53.4-58.5). By age group, 4.5% (n = 6) of people aged 20-30, 21.1% (n = 28) of people aged 31-45, 37.5% (n = 50) of people aged 46-60, and people over 61 years of age 36.8% (n = 49) respectively.Of the respondents, more than 56 or 54.9% (n = 73) were elderly, of which 63.9% (n = 85) were women and 36.1% (n = 48) were men.
A total of 36 (27.1%) leukocytes were detected, and 25 (34.2%) more (P-0.05) were detected in people over 56 years of age. The protein detected in 24 (18.0%) people, all over 56 years of age and more defined in men (P-0.01).
80.5% (n = 107) of those surveyed were diagnosed with the pathogens, and 54.9% were elderly (P-0.031). 82.4% of women and 77.1% of men were diagnosed with urinary pathogens.
Streptococcus 26%, E.coli 19%, Saprophyticus 13%, Enterococcus 11% and Staphylococcus 11% were detected in the analysis, and Streptococcus and E.coli (19%) accounted for a slightly higher rate of infection.
A total of 13 types of pathogens were identified, of which 53.4% were susceptible, 21.7% were moderately sensitive, and 24.9% were non-susceptible. Discussion: According to a study conducted by researchers at the University of Taiwan, the prevalence of asymptomatic UTI-s in the general population is 57.8%. E.Coli was also the most common bacterium in the urine [6].
In our study, there are many cases of E. coli.
Study in the United States found that the prevalence of asymptomatic bacteriuria among inpatients was 8.5%, all of them women. The most common pathogens in this study are Enterococcus bacteria. This study found that 1 in 10 people admitted to the hospital may have asymptomatic bacteriuria. [1] Conclusion
1. Asymptomatic bacteriuria in 80.5% of those surveyed 54.9% were detected in people over 56 years of age.
2. Antibiotic susceptibility of the tested pathogens was determined as 53.4% sensitive, 21.7% moderately sensitive and 24.9% insensitive.

Background: The incidence of gastric cancer has been declining worldwide in recent years; on the contrary, it has increased in the last decade in Mongolia. In Mongolia, over 80% of gastric cancer cases are diagnosed in the late stage. We performed a gastroduodenoscopy for screening and histological evaluation to diagnose gastric cancer. These methods are an effective diagnostic modality for gastric diseases; however, invasive and cause discomfort, making it an undesirable procedure for patients. Aims: To determine serum PGs and H.pylori IgG in atrophic gastritis and gastric cancer patients and evaluate the risk by ABC(D) classification. Materials and Methods: We selected 40 atrophic gastritis and 36 newly diagnosed gastric cancer patients from National Cancer Center of Mongolia, before surgery and other therapies. Besides, we enrolled population-based 38 healthy controls. Subjects of three groups were matched by age (±1) and sex. Written informed consents were obtained from all subjects. The fasting blood samples were collected and tested PGI, PGII, and H.Pylori IgG levels by enzyme-linked immunosorbent assay. Also, PGI to PGII ratio (PGI/II ratio) was calculated. We classified subjects into four groups based on ABC(D) classification. All statistical analyses were performed by SPSS (version 26.0, Chicago, IL, USA) software. Results: Median age of the subjects was 62, 52.6% (n=60) were male. Proportions of family history of gastric cancer and previous history of gastric disease were significantly higher in the gastric cancer group compared with atrophic gastritis and healthy control groups (p<0.05, p<0.05). H.pylori was positive in 67 (58.8%) subjects according to H.pylori IgG assay and there was no difference between study groups. The serum PGI level and was significantly decreased in gastric cancer and atrophic gastritis groups as compared to the healthy control (p<0.05, p<0.05). The PGI/II ratio was significantly lower in the gastric cancer group compared with the healthy control (p<0.01). The optimal cut off value of PGI was ≤35.25 ng/ml (AUC 64.3, 95% CI 51.3-77.2, p<0.05) for gastric cancer and PGI was ≤75.07 ng/ml (AUC 65.2, 95% CI 53.0-77.3, p<0.05) for atrophic gastritis. Also, the optimal cut off value of PGI/II ratio was ≤5.27 (AUC 71.6, 95% CI 69.6-82.8, p<0.01) for gastric cancer and PGI/II ratio was ≤6.25 (AUC 62.7, 95% CI 50.1-75.3, p<0.05) for atrophic gastritis. According to classification of atrophic gastritis patients and healthy control, group D had higher proportion of atrophic gastritis cases than group A, B and C (OR 5.04, 95% CI 1.13-22.50, p<0.05). According to classification of gastric cancer patients and healthy control, groups C had higher proportion of gastric cancer cases than group A, B and D (OR 6.19, 95% CI 1.04-36.78, p<0.05). Conclusion Our findings suggest that PGs level and H.pylori IgG may predict development of gastric cancer and could identifying individuals at high risk of gastric cancer and precancerous lesions who may need endoscopy.

Introduction: Cancer continues to be one of the world’s major health issues, with Mongolia continues to lead Asia in esophageal (100’000: 17.1) and gastric cancer incidence (100’000: 41.0). In the previous decade, 8,137 new cases of gastric cancer were reported in Mongolia. According to TNM staging, eight out of every ten people are diagnosed late, recognizing the need to improve people’s knowledge, attitudes, and practices. Methods: The survey was carried out using a questionnaire. A total of 320 participants between 17- 80 ages from the aimags of Uvs, Khovd, and Zavkhan were chosen at random for the survey, and data was collected through social media. SPSS (v28.0, SPSS Inc., Chicago, IL, USA) software was used for statistical analysis. Results: The survey included 110, 106, and 104 participants from the aimags of Uvs, Zavkhan, and Khovd. A total of 320 participants, with 20.9% (67) and 79.1% (253) being male and female respectively. The average age was 35.56±9.15 years. The participants’ mean knowledges, attitudes and practices scores were 7.54±2.7, 9.6±2.2, and 3.82±1.1 respectively in the first survey. Following the advocacy campaign, the mean knowledge, attitude, and practice scores increased to 9.3±2.7, 10.1±2.2, and 4.00±1.2, respectively. Conclusion The attitudes and practices of the participants were related to their level of knowledge. It is critical to increase health education and advocacy efforts in order to develop the appropriate attitudes and behaviors to reduce cancer-related deaths.
