This literature review provides a comprehensive synthesis of empirical research on tuberculosis (TB) case detection mechanisms, transmission dynamics, and associated risk factors, examining diverse epidemiological contexts across the United States, the United Kingdom, India, the Netherlands, the Dominican Republic, and Mongolia.
Specifically, the selected literature evaluates the differential transmission potential between smear-positive and smear-negative cases, quantifies secondary infection risks among close contacts, and examines the clinical utility of advanced molecular diagnostics.
The analyzed data draw upon a substantial body of empirical evidence spanning six decades, focusing primarily on the timeline from 1960 to 2020. By integrating both international and national research findings, this review highlights the significance of early tuberculosis detection and clarifies patterns of disease transmission.

Background: Osteoporosis is a systemic skeletal disease characterized by reduced bone mineral density (BMD) and deterioration of bone microarchitecture, resulting in decreased bone strength and an increased risk of fragility fractures. Early assessment of BMD is essential for identifying skeletal abnormalities and supporting clinical decision-making. Dual-energy X-ray absorptiometry (DXA) is a widely used, non-invasive method for evaluating BMD at clinically relevant skeletal sites. Aim: To assess bone mineral density using DXA and describe the corresponding T-score and Z-score measurements in adult patients. Materials and Methods: This descriptive observational study was conducted from June to October 2026 at the Department of Trauma and Orthopedic Surgery, Mongolia–Japan Hospital, Mongolian National University of Medical Sciences, Ulaanbaatar, Mongolia. Eight patients aged 18 years or older without fractures were included. According to the study records, participants were selected using a random sampling method. Demographic characteristics, height, weight, body mass index (BMI), and DXA measurements were recorded. BMD, bone mineral content (BMC), T-scores, and Z-scores were assessed at the lumbar spine, hip, and forearm. Continuous variables were summarized as means and standard deviations, and categorical variables as frequencies and percentages. Results: A total of eight patients were included, comprising five males (62.5%) and three females (37.5%). The mean age was 52.65±7.95 years, and the mean BMI was 31.59±6.32 kg/m². The mean lumbar spine (L1–L4) T-score was 0.35±1.49, and the mean Z-score was 0.97± .36. The lowest reported mean T-score was observed at the left forearm (−1.29±4.34), followed by the right forearm (−1.25±3.87). Measurements were also recorded at the left and right hip regions. The findings were descriptive and were not intended to establish population-level prevalence. Conclusions The demographic and anthropometric characteristics of the eight patients included in the study were assessed. The mean age was 52.65±7.95 years, and the mean body mass index (BMI) was 31.59±6.32 kg/m². Of the participants, 5 (62.5%) were male and 3 (37.5%) were female. The mean BMI of the participants fell within the obesity category. Bone mineral density (BMD) was assessed using dual-energy X-ray absorptiometry (DEXA) at the lumbar spine, both hips, and both forearms. The results showed variations in BMD measurements across the different anatomical sites examined. An analysis of the T-scores and Z-scores for each measurement site revealed a mean T-score of 0.35±1.49 and a mean Z-score of 0.97±1.36 at the lumbar spine. At the left hip, the mean T-score was −0.63±1.29 and the mean Z-score was 0.34±1.52, while at the right hip, the mean T-score was −0.63±1.15 and the mean Z-score was 0.31±1.09. The mean T-scores of the forearm were comparatively lower, at −1.29± 4.34 on the left side and −1.25±3.87 on the right side.

Background: Childhood overweight and obesity are important public health concerns. Assessing weight status among children presenting with fractures may provide preliminary data for further investigation of a possible association between body weight and injury. Aim: To estimate the proportion of overweight and obesity among children aged under 18 years diagnosed with fractures and compare weight-status categories by sex. Materials and Methods: This descriptive study included 30 children presenting with a fracture to the outpatient clinic of Mongolia–Japan Hospital between June and September 2026. Weight status was classified using age- and sex-adjusted BMI-for-age. We summarized continuous variables as mean±standard deviation, median, quartiles, and minimum–maximum values; we reported categorical variables as counts and percentages. The Mann–Whitney U test and Fisher’s exact test were used, with p<0.05 considered statistically significant. Results: Of the 30 children, 20 (66.7%) were boys and 10 (33.3%) were girls. Eighteen children (60.0%) were classified as overweight/obese. Mean BMI was 20.58±3.44 kg/m² and median BMI was 19.82 kg/m². Mean BMI was higher in the overweight/obesity group than in the normal-weight group (22.00±3.55 vs 18.46±1.90 kg/m²; p=0.0092). Sex was not statistically associated with weight-status category (p=1.000). Conclusion The prevalence of overweight and obesity among children under 18 years of age diagnosed with bone fractures was 60.0%. The body mass index (BMI) was statistically significantly higher in children with overweight and obesity than in those with normal weight. Sex was not statistically associated with excess body weight. Further studies with larger sample sizes, a control group, and bone mineral density measurements are needed to determine the relationship between excess body weight, bone health, and fracture risk in children with bone fractures.

Background: In the treatment of plaque-induced gingivitis, in addition to mechanical plaque control, the use of chemical plaque control such as mouth rinses for a certain period has shown a positive effect on treatment outcomes and prognosis. Aim: To evaluate the efficacy of a probiotic mouthwash in the treatment of plaque-induced gingivitis. Materials and Methods: A randomized controlled clinical trial was designed for a period of 2 weeks on 45 systemically healthy subjects between 20 and 25 years having plaque-induced gingivitis. The study population was divided into three groups. Group 1-15 subjects were advised experimental (probiotic) mouthwash. Group 2-15 subjects were advised positive control (chlorhexidine) mouthwash and Group 3-15 subjects into a negative control group. Oral prophylaxis was done for all groups at baseline. After the proper oral hygiene instructions, groups 1 and 2 were instructed to rinse their mouth with 15 ml of their respective mouthwashes, for 1 min twice daily, 30 min after brushing. Clinical parameters such as Full mouth plaque score (FMPS), Full mouth bleeding score (FMBS) were assessed at baseline, 2 weeks respectively. Results: At baseline, there was no statistically significant difference between the groups in terms of FMBS and FMPS mean values (p=0.174, p=0.887). At day 14, the FMPS, FMBS mean values were significantly reduced by all treatment modalities ranking probiotic and chlorhexidine is greater than negative control group (p<0.001, p<0.001). Conclusion The probiotic mouthwash was effectively used as an adjunct to mechanical plaque control in the treatment of plaque-induced gingivitis.

Background: The skin barrier serves as the primary defense against environmental factors. Mongolia’s extreme climate conditions may contribute to skin barrier impairment, increased trans-epidermal water loss (TEWL), and decreased skin moisture. Objective: To determine and compare skin moisture, TEWL, and skin pH levels in children. Methods: A cross-sectional study was conducted in June 2023 with 104 relatively healthy children selected through random sampling. Skin physiological parameters, including skin moisture, skin pH and TEWL were measured following the EEMCO (European Group on Efficacy Measurement of Cosmetics and Other Topical Products) guidelines using the Multi Skin Test MC750 device (Courage+Khazaka Electronics, Germany) at nine different sites. Data analysis was performed using Microsoft Excel and Stata-14 software. Results: Among the participants, 51.9% (n=54) reported having dry skin (p<0.0001). Additionally, 64.5% (n=67) used moisturizers, but their usage did not show a statistically significant difference in skin moisture (p=0.929), skin pH (p=0.378), or TEWL (p=0.332). 14.42% (n=15) had extremely dry skin, while 85.58% (n=89) had dry skin, with no participants falling within the normal skin moisture range. TEWL showed a moderate inverse correlation with age (r=-0.331, p=0.0006). When analyzed by age groups, skin moisture (p=0.023) and TEWL (p=0.038) differed significantly between groups. Conclusion Skin moisture and TEWL significantly differ across age groups. Given that all participants had dry skin, moisturization is crucial. Mongolia’s extreme climate is likely a key contributing factor to childhood skin dryness.

Preparation of the water Extract from Antidiabet-31:10 was suspended in distilled water (100 mL) and allowed to stand at 4◦C. It was then filtered through several layers of muslin cloth and filtrate (water extract) was discarded Male Shinshila rabbits, weighing 1.5–2.7 kg, were rendered diabetic with an injection of 100 mg/kg alloxan monohydrate into a marginal ear vein. To reduce risk of nephrotoxicity from hyperuricemia, a 7 ml/kg body wt intravenous injection of 0.9% saline was given immediately after the injection ofalloxan. To counteract initial hypoglycemia, 3.5– 4.0 g glucose/kg body wt was given subcutaneously [27.5% (wt/vol) solution] 5– 6 h after the injection of alloxan. Diabetes was defined by a blood glucose concentration 16.9 mmol/l on 1 day. The total number of rabbits used was 28. Plasma was obtained by centrifugation of blood glucose, plasma aspartate aminotransferase (AST), alanine aminotransferase (ALT), cholesterol,triglycerides (TG), ‘’Humylazer 2000’’ chemistry analyzers automated (Human, Germany). As shown in Table 1, showed significant antihyperglycemic activity (p<0.05). Antidiabet-3 (AD3) and control failed to achieve euglycemia but caused a significant (p< 0.05) reduction in glucose levels compared to their initials values. The result of the experiment were confirmed that using by blood glucose in antidiabet-3 treatment groups taken for an observation at 3 dayfrom it was decreased to 22.20±2.5 (2.88%), post 7 day it was decreased 19.03±2.75 (14.3%), post 14 day it was 14.86±0.80 (33.06%), which it is showed may increase the blood glucose from diabetic rabbits.
