Background: Renal cell carcinoma (RCC) accounts for 85–90% of all primary renal malignancies in adults and 1–3% of all cancers worldwide, with incidence rising steadily year by year. Clear cell (ccRCC), papillary (pRCC), and chromophobe (chRCC) subtypes differ significantly in genetic alterations, biological behavior, and treatment response, making preoperative subtype identification clinically important. Conventional qualitative CT assessment is limited, and contrast-enhanced CT-based radiomics may represent a novel diagnostic approach. Aim: To develop a model for preoperative differentiation of ccRCC from non-ccRCC subtypes using contrast-enhanced CT-based radiomics, and to evaluate its diagnostic performance through internal and external validation. Materials and Methods: A retrospective study was conducted on 121 patients with histopathologically confirmed RCC treated at the Urology–Andrology Center of the First Central Hospital of Mongolia between 2021 and 2024. Patients were categorized into ccRCC (n=84) and non-ccRCC (n=37) groups. Tumor segmentation was performed on corticomedullary phase CT images using 3D Slicer software, and a total of 122 radiomic features were extracted, including first-order uniformity, gray-level co-occurrence matrix (GLCM), gray-level run-length matrix (GLRLM), shape flatness, and GLCM maximum probability. Diagnostic performance was assessed by ROC analysis, and model generalizability was evaluated through external validation (n=73). Results: GLRLM demonstrated a statistically significant difference between the ccRCC (mean 0.1230) and non-ccRCC (mean 0.0170) groups (p<0.001). ROC analysis yielded an optimal cut-off value of 0.1493 for GLRLM, with an internal validation AUC of 0.9103, sensitivity of 83.3%, and specificity of 92.3% (p<0.01). External validation (n=73) achieved an AUC of 0.860 and an accuracy of 86.0%, confirming the model’s generalizability. First-order uniformity (AUC=0.880) and variance (AUC=0.862) showed comparable discriminative performance to GLRLM, whereas flatness (AUC=0.584) and GLCM Imc2 (AUC=0.621) demonstrated relatively poor discriminative ability. Confusion matrix analysis yielded an accuracy of 86.0% in both internal and external validation cohorts. Conclusion Non-invasive CT-based radiomics demonstrates the ability to accurately differentiate RCC subtypes preoperatively with high precision (AUC=0.92), as confirmed by both internal and external validation.

Background: Cardiovascular disease (CVD) remains the leading cause of death worldwide, accounting for approximately 19.8 million deaths in 2022, or 32% of all deaths. Insulin resistance is an important pathophysiological mechanism not only in the development of type 2 diabetes mellitus (T2DM) but also in the development and progression of cardiovascular disease. Evidence remains limited regarding the simultaneous assessment of associations between selected anthropometric measures and insulin resistance in patients with ischemic heart disease (IHD). Aim: To investigate the association between waist-to-height ratio (WHtR) and insulin resistance indices (TG/HDL and HOMA-IR) in patients with chronic ischemic heart disease. Materials and Methods: This hospital-based cross-sectional study included 274 patients aged 40–75 years. Written informed consent was obtained from all participants. Data were collected using a structured questionnaire, anthropometric measurements were performed, and peripheral blood samples were collected. Laboratory measurements included fasting lipid profile, fasting glucose, and fasting insulin levels. WHtR was calculated as waist circumference (cm) divided by height (cm). Insulin resistance was assessed using the TG/HDL ratio, calculated as TG (mmol/L) divided by HDL (mmol/L), and the HOMA-IR index. Metabolic syndrome was defined according to the Joint Interim Statement (JIS-2009) criteria. Results: Among the 274 participants, 209 (76.3%) were male and 65 (23.7%) were female, with a mean age of 61.1±7.9 years. WHtR was significantly and positively correlated with HOMA-IR, with a weak-to-moderate correlation (Spearman’s ρ=0.303, p<0.001). A weak but statistically significant positive correlation was also observed between WHtR and the TG/HDL ratio (ρ=0.136, p=0.039). The discriminative ability of WHtR for insulin resistance was moderate (AUC=0.645, 95% CI: 0.562–0.729; p=0.001). The optimal cutoff value determined using the Youden index was 0.60, with a sensitivity of 63.2% and specificity of 64.2%. Multivariable logistic regression analysis showed that WHtR ≥0.60 was independently associated with insulin resistance. Conclusion WHtR was significantly and positively associated with HOMA-IR and the TG/HDL ratio, and WHtR ≥0.60 was independently associated with insulin resistance.

Background: Serum natriuretic peptide (NT-proBNP) is a critical biomarker for diagnosing left ventricular dysfunction. Heart failure is the leading cause of mortality in chronic kidney disease (CKD), emphasizing the need for its early detection and prognosis. Objective: This study aimed to determine the serum NT-proBNP levels in participants with CKD and establish a cut-off value for predicting heart failure. Methods: A descriptive cross-sectional study was conducted from April 1 to July 1,2024. This study received approval from the Ethics Committee of the Institute of Medical Sciences (Approval No.24/01). A total of 117 CKD patients hospitalized in the Nephrology and Endocrinology Department of the third state hospital were enrolled based on predefined inclusion and exclusion criteria. Data were collected using questionnaires, laboratory and heart ultrasound test results. Serum NT-proBNP levels were measured using a rapid immunofluorescence quantitative analyzer. Data were analyzed with SPSS 26.0. Results: The mean age of the 117 participants was 57.9 ± 14.7 years, with 51.3% being male. The mean serum NT-proBNP level was 7686 ± 12149 pg/mL. Statistically significant differences were observed in serum creatinine, sodium, calcium, CKD stage, and arterial hypertension between genders (p<0.05). NT-proBNP levels in hemodialysis patients differed significantly between heart failure and non-heart failure groups (p<0.05). Significant differences were also found in hemoglobin, serum albumin, NT-proBNP levels, and CKD stages (p<0.05). NT-proBNP correlated significantly with risk factors such as hemodialysis, diabetes, and decreased systolic blood pressure (p<0.0001). A weak inverse relationship was noted between systolic blood pressure and NT-proBNP (R² = 0.16). The NT-proBNP cut-off value for predicting heart failure was 3027 pg/mL, with an AUC of 61.7% (sensitivity: 74.5%, specificity: 55%). Conclusion Serum NT-proBNP levels are elevated in CKD patients regardless of heart failure. The established cut-off value for NT-proBNP in CKD patients to detect heart failure was 3027 pg/mL, with moderate diagnostic utility (AUC = 61.7%).

Chronic kidney disease (CKD) is a global health issue characterized by a gradual loss of kidney function over time. As the disease progresses, it leads to an increased risk of cardiovascular complications, which are the leading cause of morbidity and mortality in CKD patients. B-type natriuretic peptide (BNP) and its inactive fragment, N-terminal pro b-type natriuretic peptide (NT-proBNP), are biomarkers widely used in the diagnosis and management of heart failure. Their role in CKD, however, is complex due to the overlapping pathophysiological mechanisms between cardiac and renal dysfunctions. This literature review aims to explore the diagnostic and prognostic value of BNP and NT-proBNP in patients with CKD, highlighting their clinical relevance, the impact of renal function on their levels, and potential therapeutic implications. The review focuses on studies published in the last decade, examining the clinical applications, outcomes, and challenges associated with using BNP and NT-proBNP as biomarkers in CKD patients.

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.

Most of the infected patients completely recovered after covid-19 infection. However, a substantial proportion of patients who have been infected with SARS-CoV-2 continue to have symptoms long past the time that they recovered from the initial phases of covid-19 disease. At NICE guideline,
1. Acute covid-19: signs and symptoms of covid-19 for up to 4 weeks,
2. Ongoing symptomatic covid-19: signs and symptoms of covid-19 from 4 to 12 weeks,
3. Post-covid-19 syndrome: signs and symptoms that develop during or after an infection consistent with covid-19, continue for more than 12 weeks and are not explained by an alternative diagnosis.
In addition to the clinical case definitions, ‘long covid’ is commonly used to describe signs and symptoms that continue or develop after acute covid-19. As the pandemic of covid-19 continues, numerous additional symptoms, such as fever, dry cough, shortness of breath, fatigue, myalgias, vomiting or diarrhea, headache and weakness. Other critical and severe complications of covid-19 can include impaired function of the heart, brain, lung, liver, kidney, and coagulation system. Early reports have now emerged on post-acute infectious consequences of covid-19, with studies from the United States, Europe and China reporting outcomes for those who survived hospitalization for acute covid-19. An observational cohort study from 38 hospitals in Michigan, United States evaluated the outcomes of 1,250 patients discharged alive at 60 day. Of 488 patients who completed the telephone survey in this study, 32.6% of patients reported persistent symptoms. Dyspnea while walking up the stairs 22.9% was most commonly reported, while other symptoms included cough 15.4% and persistent loss of taste/smell 13.1%. Post-hospital discharge care of COVID-19 survivors has been recognized as a major research priority by professional organizations.
