Background: Central serous chorioretinopathy (CSCR) is described by researchers as a condition that results from fluid under the retinal pigment epithelium, originating from the choroid of the eye. This disease usually affects the central part of vision and may resolve on its own over time, though in some cases, it can persist for long periods or recur. In our country, there is a lack of research regarding this condition, which led to the motivation for gathering and reviewing existing works on this topic. Aim: To collect and analyze a review of the studies on central serous chorioretinopathy (CSCR). Methods: We reviewed and analyzed literature related to CSCR published in electronic sources such as Thomson Reuters, PubMed-central database, and Google Scholar using literature review methods. Results: CSCR is most commonly seen in individuals aged 35-55 years, with a significantly higher prevalence in men (9.9/100,000) compared to women (1.7/100,000). Researchers found that the prevalence of CSCR is nearly the same among populations in Europe, Africa, and Asia. CSCR typically affects one eye, but it occurs in both eyes in up to 40% of cases. Weenink A (2001) studied the family members of 27 patients with bilateral CSCR, finding that 52% of family members had been diagnosed with CSCR, and 27.5% of them had chronic CSCR in at least one eye. This suggests a potential genetic predisposition to CSCR. According to researchers, while CSCR can be diagnosed clinically, additional imaging techniques like fluorescein angiography and optical coherence tomography are frequently used to rule out other diagnoses and guide treatment. Conclusion CSCR generally has a favorable prognosis, but recurrences and its effects on visual function indicate the need for effective management strategies. To maintain long-term visual improvement, it is essential to provide healthcare services tailored to the patient’s specific conditions and risk factors.

Background: Accreditation of healthcare institutions serves as a fundamental mechanism for ensuring patient safety and validating the quality of medical services provided to the population. At Intermed Hospital, a quality measurement system for healthcare services has been established since 2015, encompassing 126 quality indicators at both institutional and departmental levels. This system facilitates continuous quality improvement efforts. In this context, quality indicators specific to the endoscopy department play a pivotal role in objectively assessing the quality of endoscopic services. Aim: To assess the quality indicators in gastrointestinal endoscopy unit. Materials and Methods: A retrospective single-center study was conducted by collecting data from the Intermed hospital’s electronic information systems which included HIS and PACS and Quality and Safety Department’s Database and the results were processed using the SPSS software. Ethical approval was granted by the Intermed hospital’s Scientific research committee. The quality of endoscopic services in the Intermed hospital was assessed based on: a) the average values of four quality indicators measured monthly; b) sample survey data from five categories of quality indicators. Results : Between 2016 and 2024, the quality indicators of the endoscopy unit measured as the level of early warning score evaluations for patients was 95.97%±3.33, the level of cases where peripheral blood oxygen saturation decreased during sedation was 1.54%±3.78, the level of cases where patients experienced paradoxiical response during sedation was 5.82%±1.75, surveillance culturing level for validation of endoscopy reprocessing was 11.6%. The endoscopic documentation quality by peer review showed 95.7-100%, the colonoscopy quality indicators were followings as adenoma detection rate: 24.5% Cecal intubation rate: 99.1%, 95.2%, Colonoscope withdrawal average time: 13.28±10.62 minutes, Bowel preparation quality (Boston Scale): 89.3% 95.7%), patient discharge from the recovery room, Average discharge time post-procedure: With propofol alone: 30.92 minutes; With propofol and fentanyl combined: 31.52 minutes, The intermediate risk was 0.28% by the TROOPS evaluation during procedural sedation. Conclusion The quality benchmark levels for these endoscopic units, as determined by a single-center study, can be effectively implemented by benchmark endoscopy centers to enhance their quality and safety operations.

Staphylococcus aureus (S. aureus) is a clinically significant pathogen widely distributed in food production environments. Its ability to form biofilms on food contact surfaces enhances 50 environmental persistence, increases antibiotic resistance 10–1500-fold, and poses serious challenges for food safety and public health. In Mongolia, data on the biofilm-forming ability of S. aureus in meat processing and retail environments are limited. A cross-sectional study was conducted on 437 samples collected from meat supply and retail sites, including raw meat, aprons, counters, trolleys, and workers’ hands. Isolation and confirmation of S. aureus were performed using MNS 6308:2012 and ISO 6888-1:2021 standards, followed by PCR amplification of the species-specific nucA gene (270 bp). Biofilm formation was evaluated using the microtiter plate assay with 0.5% glucose supplemented tryptic soy broth and optical density at 490 nm, and confirmed by scanning electron microscopy (SEM). Statistical analyses were performed using chi-square tests with p< 0.05 considered significant. Of the 437 samples, 14.2% (62/437) were contaminated with S. aureus. Contamination was higher in retail markets (25.9%) than supply sites (9.3%). Among isolates, 40.3% exhibited biofilm-forming ability: 29.0% weak, 9.7% moderate, and 1.6% strong. Biofilm formation did not significantly differ by sampling site or sample type (p>0.05). SEM imaging revealed distinct biofilm architectures with polysaccharide matrices at 80,000× magnification. A considerable proportion of S. aureus isolates from meat processing and retail environments exhibited biofilm forming ability, posing a potential risk for cross-contamination and persistent foodborne transmission. Strengthened hygiene and sanitation measures are essential to control biofilm-associated S. aureus contamination in Mongolia’s meat production and supply chain.

Background: The COVID-19 pandemic has profoundly impacted mental health, particularly exacerbating conditions such as depression, anxiety, insomnia, post-traumatic stress disorder (PTSD), and emotional disorders among hospitalized patients. This study examined the prevalence of COVID-19-related mental health issues and risk factors in hospitalized patients affiliated with MNUMS, compared to a control group. Aim: To assess the prevalence of mental health disorders such as depression, anxiety, insomnia, and post-traumatic stress disorder (PTSD), and to identify their associated risk factors. Materials and Methods: The study was conducted at hospitals under MNUMS, including the Mongolian-Japanese Hospital, Central Hospital, and the National Center for Maternal and Child Health. A total of 552 participants (399 case group, 153 control group) who were hospitalized were included. Depression (PHQ-9≥10), anxiety (GAD-7≥10), insomnia (ISI≥15), and PTSD (PCL-5≥33) were assessed using standardized scales. Analysis was performed using chi-square tests and binary logistic regression (crude odds ratio [cOR]/adjusted odds ratio [aOR], 95% confidence interval [CI]), adjusted for group, age, and sex. Results: In the case group, depression (23.1% vs. 13.7%, p=0.015, cOR=1.884 [1.124-3.156]), anxiety (16.8% vs. 11.1%, p=0.096), and any mental disorder (18.0% vs. 13.7%, p=0.225) were higher, while insomnia was lower (19.5% vs. 30.1%, p=0.008). PTSD was low overall (1.8% vs. 0.7%, p=0.333). Risk factors included female sex (p<0.001, cOR=0.362 for depression in males), younger age (p=0.004), unemployment (p=0.017), and prior trauma (p<0.001). COVID-19 symptoms (difficulty breathing) increased the risk of depression (p<0.001, cOR=2.828 [1.708-4.682]). Conclusion Hospitalization for COVID-19 increases the risk of depression and anxiety, modulated by demographic, clinical, and socioeconomic factors. Targeted interventions for vulnerable groups are essential.

Background: In Mongolia, 7,244 new cancer cases were registered in 2023, of which 5.9% (425 cases) were cervical cancer. The prevalence of cervical cancer is 14.5 per 10,000 populations. In Ömnögovi province, 597 cancer cases were recorded in 2023, and 18.5% of them were cervical cancer. The cervical cancer screening coverage in Ömnögovi province was 45.6% in 2023. Aim: To identify the types of human papillomavirus (HPV) among women aged 30 years and above in Dalanzadgad soum. Materials and Methods: A cross-sectional study design was used. We included 100 women aged 30 years and above in Dalanzadgad soum. HPV genotyping was performed using polymerase chain reaction (PCR) among women diagnosed with cervical erosion. A 44-item questionnaire was also administered to assess the risk factors for cervical cancer. Results: HPV was detected in 41% of participants, while 59% tested negative. Among the participants, 25 had one genotype, 13 had two genotypes, and 3 had three genotypes. Among the 41 women who tested positive, 49% had high-risk genotypes. A total of 20 HPV genotypes were identified, including 16 high-risk and 4 low-risk types. Of the HPV-positive women, 65.9% were married, and 58.5% had only one lifetime sexual partner. In addition, 78% of participants reported never having undergone cervical cytology screening prior to this study. Conclusion In Dalanzadgad soum, 2 out of every 5 women are at risk of HPV infection, and among those infected, 1 out of 2 carry a high-risk HPV genotype.

Background: The COVID-19 pandemic has triggered a global mental health crisis. According to WHO estimates, anxiety and depression rose by 25% in the first year. In the post-COVID era, over 70% of patients experience depression, anxiety, insomnia, PTSD, and OCD, which can persist for up to 24 months. Hospitalized individuals face heightened risks due to infection severity, treatment stress, and social isolation. However, studies examining treatment outcomes and influencing factors remain limited. In Mongolia, mental health issues escalated sharply from 2020 to 2022; WHO data indicate that anxiety and stress were prevalent among healthcare workers and patients. Children and youth were particularly affected, with UNICEF studies emphasizing the urgent need for intervention. Suicide rates increased from 18.3 per 100,000. Long-term research on post-COVID mental disorders is scarce, impeding policy formulation. This study evaluates treatment outcomes in COVID patients and identifies key factors. By comparing case and control groups at 3 and 12 months, it uncovers differences in symptoms and treatment responses. The comparative design assesses statistical significance via P-values and subgroup success rates for CBT and SSRI therapies. Findings will enhance Mongolia’s mental health services. Larger-scale studies are essential moving forward. Objective: To evaluate treatment outcomes for post-COVID mental disorders and identify influencing factors. To analyze differences in psychological symptoms and treatment between case (COVID-19 positive) and control groups over 3 and 12 months. Material and Method: Retrospective comparative analysis of records from 281 patients (cases n=181, controls n=100) at a unified hospital from 2020-2022. At 12 months, n=200 (cases n=100, controls n=100). Patients were categorized by anxiety, depression, insomnia, and stress-related symptoms, with P-values calculated. Detailed subgroup analysis (n=47 treated patients) was conducted. Results: At 3 months, cases showed higher anxiety (56.4%, P=0.002), depression (41.4%, P<0.001), and insomnia (58%, P=0.107). At 12 months, differences lessened but anxiety (52%, P=0.023) and depression (35%, P=0.042) remained significant. COVID-related new symptoms were elevated in cases (e.g., depression 24.3%, P<0.001). Treatment subgroup success was 95.7% (P<0.001), with duration influencing outcomes (P=0.03). Conclusion Post-COVID mental symptoms persist long-term in cases, and extended treatment durations yield better results. Larger studies are required

Neuromyelitis optica (NMO) is an autoimmune, inflammatory, demyelinating disorder characterised by attacks within the spinal cord and optic nerve. The purpose of this review is to understand the evidence for the effectiveness of plasmapheresis as an add-on therapy for NMO spectrum disorders (NMOSD). The current diagnostic criteria for NMO include optic neuritis, acute myelitis, and at least two of the following three supportive criteria: contiguous spinal cord MRI lesions extending over ≥3 vertebral segments, brain MRI not meeting diagnostic criteria for multiple sclerosis, and NMO-seropositive status.⁵ Myelitis presents with paraparesis and sensory loss below the lesion, sphincter loss, dysaesthesia, and radicular pain.

Background: Worldwide, the leading cause of blindness in people over the age of 50 is age-related macular degeneration (AMD), which is a complication of the exudative “wet” and dry type. AMD is a multifactorial neurodegenerative disease relating with a combination of environmental and genetic factors, and a contribution of age effect and smoking also, obesity was investigated to be associated with the disease. Number of previous studies have shown that the polymorphisms in the ARMS2, CFH and VEGF-A genes are associated with AMD. Therefore, we investigated the associations between the five common vascular endothelial growth factor (VEGF) polymorphisms and AMD with its therapeutic results. Materials and Methods: Totally 161 AMD patients and 223 controls were enrolled in this case-control study. A prospective analysis of 66 eyes of 34 patients with neovascular AMD evaluated intravitreal bevacizumab injections. The polymorphisms in CFH, ARMS2 and VEGF-А were detected by using the methods of allele-specific polymerase chain reaction (ASPCR) and PCR based restriction fragment length polymorphism (RFLP). Statistical analyses were performed by SNPalyze software. Results: Results of the study showed that rs1061170, rs1065489, and rs800292 polymorphisms are associated with arterial hypertension. Anti-coagulant intake rs1061170 polymorphism T/C, C/C/C/C risk genotype (OR=5.04, 95% CI, 1.81-14.09, p=0.002, RERI=2.568, AP=0.509, S=2.7302) , combined effect of G/C/C/C/ /G, G/A risk genotype (OR=6.52, 95% CI, 2.88 14.79, p<0.001, RERI=4.187, AP=0.642, S=4.136) are associated with increased risk of AMD. In the study, in 66 eyes of a total of 34 people who received intravitreous injection treatment, the central retinal thickness before and after treatment was 294.59±83.52 before treatment, 262.74±87.02 on the first day after treatment, 259.5±111.83 after one month, 248.98±84.96 after 3 months, and 262.69 after 6 months. ±110.59, after 1 year it decreased to 259.19±112.29 (95% CI, 226.74-291.65), which is a statistically significant difference. A comparative study of polymorphisms in therapeutic and non-therapeutic groups revealed statistically significant differences in the G/G groups of rs2010963 polymorphisms. Also, people with G/G genotype of rs2010963 polymorphism are more effective in treatment than people with other genotypes. Conclusion Individual factors such as not wearing sunglasses and arterial hypertension and using anti coagulant medication have been identified as risk factors for AMD. The result showed that polymorphisms of ARMS2, CFH, VEGF genes can be a genetic risk factor for AMD. The decreased in central retinal thickness and improving VA after anti-VEGF treatment confirm the effectiveness of the treatment. Also, people with G/G genotype of rs2010963 polymorphism are more effective in treatment than people with other genotypes. Identification of genetic markers that affect clinical response may result in optimization of anti-VEGF therapy.

Emergency cesarean section risk factors of Robson 1, 2A, 3, 4A Introduction: Cesarean section rates in Mongolia exceed WHO recommendations of 5–15%, reaching 27.6% nationally and 34.1% at the First Maternity Hospital between 2019–2023. C-sections, while life-saving, increase risks of hemorrhage, infection, uterine complications, and reduced maternal quality of life. This study aimed to analyze emergency C-sections by Robson classification and identify associated risk factors in groups 1, 2a, 3, and 4a. Material and methods: A retrospective case-control study was conducted using 886 medical records (443 emergency C-sections and 443 vaginal deliveries) from 2021–2023. Data were analyzed with IBM SPSS 24.0, and binary logistic regression was used to calculate odds ratios (OR) with 95% confidence intervals (CI). Results: Robson 2a was the most frequent category (43.8%), followed by 4a (25.7%), 1 (20.1%), and 3 (10.4%). Significant risk factors for emergency C-section included maternal age (p<0.001), early cervical dilation (<5 cm) at labor diagnosis (OR 3.54), abnormal CTG, pre-eclampsia, PROM, amniotomy, infertility, and malposition. Multivariate analysis showed PROM (aOR 14.66), amniotomy (aOR 6.85), fetal weight ≥4000 g (aOR 4.07), and maternal age (aOR 1.48) as key predictors. Conclusions: Emergency C-sections were most common in Robson group 2a. Major contributing factors included PROM, amniotomy, maternal age, macrosomia, and abnormal labor patterns. Targeted interventions to manage these risk factors could reduce unnecessary emergency C-sections.
