Background: It is a well-established fact that late-life depression represents a significant public health issue, particularly in low- and middle-income countries experiencing rapid demographic aging. Although its clinical and societal impacts are well-recognized, data on the interplay between depressive symptoms and functional status in older populations remain limited for Türkiye. This study aimed to estimate the prevalence of depression among individuals aged 65 years or older, examine its associations with instrumental and basic activities of daily living, and identify key sociodemographic and behavioral correlates. Methods: In this study, data obtained from a population-based survey in 2264 clusters by the Turkish Statistical Institute (TUIK) were used, and weighted data were yielded from 6,036,396 adults aged 65 and over. Depression was measured using the Geriatric Depression Scale (GDS), categorizing participants as “not depressed”, “mildly depressed”, or “severely depressed”. Functional status was evaluated using the Lawton–Brody Instrumental Activities of Daily Living (IADL) Scale and the Katz Activities of Daily Living (ADL) Scale. Logistic regression models, adjusted for age and body mass index (BMI), were used to determine the associations of depression with functional impairment and various covariates, including gender, education, marital status, chronic disease, physical activity, smoking, and alcohol use. Results: Overall, the prevalence of depression in this cohort was 49.9% [95% CI = 48.7–51%], with 36.0% [95% CI = 34.8–37.0%] classified as mild and 13.9% [95% CI = 13.1–14.7%] as severe depression. IADL and ADL scores were negatively correlated with GDS scores (r = −0.416 and r = −0.321, respectively; p < 0.001). In logistic models, lower IADL scores were linked to higher odds of mild (OR = 0.797, 95% CI = [0.796–0.798], p < 0.001) and severe depression (OR = 0.689, 95% CI = [0.688–0.690], p < 0.001). Being semi-dependent or dependent in ADL further escalated depression risk. Female gender, lower education, single/divorced status, chronic disease, and inactivity also emerged as strong predictors. Conclusions: The findings of this study suggest that depression is highly prevalent among older adults in Türkiye, with functional impairment, unfavorable health behaviors, and sociodemographic vulnerabilities heightening risk. Integrating depression screening into geriatric care—alongside interventions to maintain functional independence—may help mitigate the burden of late-life depression in similar contexts.

Background/Aims: Acute pancreatitis (AP) is a common and potentially severe condition, and early identification of its severity is critical for appropriate clinical management. This study aimed to investigate the role of the Neutrophil-Lymphocyte Ratio (NLR) and Lactate dehydrogenase (LDH)/Albumin Ratio (LAR) in predicting the severity and prognosis of patients with AP and to determine the optimal NLR value. Materials and Methods: The demographic, clinical, and laboratory data of patients diagnosed with AP were retrospectively analyzed. Neutrophil-Lymphocyte Ratio was measured at admission (0 hours), and at 24 and 48 hours; C-reactive protein (CRP) values were recorded at 0 and 48 hours; and the LAR was calculated based on LDH and albumin values measured at 48 hours post admission. These values were compared with disease severity, mortality, organ failure, length of hospital stay, and the need for intensive care according to Ranson and bedside index of severity in AP (BISAP) scores. Results: According to the BISAP scoring, 38 patients (16%) were classified as having severe AP, while 200 patients (84%) had mild AP. The best parameter for predicting severe AP was found to be the 24-hour NLR with a sensitivity of 79% and specificity of 67%. The best parameter for predicting mortality and organ failure was the NLR at 48 hours. There was a statistically significant difference between the length of hospital stay and the need for intensive care with the CRP value at 48 hours. Additionally, there was a statistically signifi cant relationship between LAR and mortality, length of hospital stay, organ failure, and the need for intensive care. Conclusion: This study demonstrates that the NLR and the LDH/Albumin Ratio are important and easily accessible markers for determining the severity and prognosis of AP. The NLR at 48 hours is an effective parameter for predicting mortality and organ failure, while the LDH/Albumin Ratio is significant in predicting mortality.

MPOX (Monkeypox) is a zoonotic disease of increasing global concern due to its re-emergence and potential for human-to-human transmission. Effective public health interventions rely on understanding socio-demographic determinants of knowledge and perceptions of the disease. This study aimed to investigate MPOX-related knowledge and concerns among a diverse sample in Türkiye, identifying key factors influencing knowledge levels. A cross-sectional study was conducted with 509 participants aged 18–73 years (mean age: 33.8 ± 15.6) in all settlements of Türkiye. Socio-demographic data were collected, and MPOX knowledge and concerns were assessed using a structured data form. To assess knowledge levels regarding MPOX, 15 questions were defined with 1 point given for each correct answer, and these questions were then categorized as high knowledge (≥ 10 correct answers) and low knowledge (< 10 correct answers). Univariable and multivariable binary logistic regression analyses were conducted to identify factors associated with knowledge levels. Trust and reliance on information sources were also evaluated. The data form was distributed to participants via social media platforms. The majority of participants (97.1%) were aware of MPOX, but only 6.5% believed adequate precautions were in place. The mean knowledge score was 7.6 ± 3.7, with 37.7% demonstrating high knowledge. In terms of concerns about MPOX, only 31.6% of participants were identified as concerned, whereas the majority (68.4%) of the participants reported no significant concerns. The most trusted source of information about MPOX among the participants was medical doctors and healthcare professionals, as indicated by 53.63% of respondents. Low knowledge was significantly associated with older age (p = 0.015), female gender (p = 0.002), lower education levels (p < 0.001), non-medical fields (p < 0.001), and lower income (p < 0.001). Social media (53.11%) was the most common information source, yet healthcare professionals (53.63%) were the most trusted. Multivariable logistic regression confirmed that being in non-medical fields (OR = 2.858, 95% CI: 1.809–4.515, p < 0.001), lower income (OR = 3.141, 95% CI: 2.015–4.896, p < 0.001), and perceived low immunity (OR = 2.264, 95% CI: 1.350–3.797, p = 0.002) independently predicted lower knowledge. Despite high awareness, significant gaps in MPOX knowledge exist, particularly among older adults, females, non-medical professionals, and those with low income. Public health strategies should prioritize these groups, leveraging trusted sources like healthcare professionals while improving the reliability of digital information platforms.

Background/Aims: Double-balloon enteroscopy (DBE) allows for the diagnoses and treatment of small bowel tumors (SBTs). This study aimed to evaluate the utility of DBE for the diagnosis and treatment of SBTs.Methods: Patients diagnosed with SBTs who underwent DBE were included in this study. According to their endoscopic appearances, they were categorized as polyps or masses, and according to their histological characteristics, they were categorized as benign or malignant SBTs.Results: A total of 704 patients were retrospectively analyzed, and 90 (12.8%) were diagnosed with SBTs. According to their endoscopic appearance, 48 (53.3%) had polyps and 42 (46.7%) had masses. Additionally, 53 (58.9%) and 37 (41.1%) patients had malignant and benign SBTs, respectively, depending on their histological characteristics. Patients diagnosed with polyps were younger than those diagnosed with masses (p<0.001). Patients diagnosed with benign SBTs were younger than those diagnosed with malignant SBT (p<0.001). Overall, histological diagnosis was determined using DBE in 73 (81.1%) patients.Conclusions: DBE is a useful method for diagnosing SBTs. Additionally, the histological type of the lesion can be determined using DBE.

Background/Objectives: This study aimed to determine the prevalence of malnutrition and sarcopenia risk among patients hospitalized in gastroenterology clinics across different geographical regions of Turkey, to identify their risk factors, and to evaluate their associations with clinical outcomes. Methods: A total of 1051 patients admitted to 36 gastroenterology clinics across six geographical regions of Turkey during the week of 14 November 2024 were evaluated in a cross-sectional design. The nutritional status of the patients was assessed using the NRS-2002 questionnaire, while the risk of sarcopenia was evaluated with the SARC-F questionnaire. Demographic data, clinical diagnoses, disease severity scores, and comorbidities were also recorded and analyzed. Results: Of the patients included in the study, 54.7% were female, and the mean age was 61.7 ± 17.2 years. The prevalence of malnutrition risk was 27.8%, while the prevalence of sarcopenia risk was 32.7%. Patients with malnutrition risk had a lower BMI (24.7 ± 5.3 vs. 27.1 ± 5.4, p < 0.001) and were older (67.6 ± 16.0 vs. 56.5 ± 17.1, p < 0.001). The risks of sarcopenia and malnutrition were significantly higher in patients with liver cirrhosis (40.7% malnutrition; 54.5% sarcopenia), gastrointestinal malignancy (50.5%; 44.2%), and diabetes mellitus. Logistic regression analysis identified older age, male sex, and presence of malignancy as independent risk factors for malnutrition, whereas older age, female sex, presence of malnutrition, liver cirrhosis, and heart failure were independent risk factors for sarcopenia. A strong correlation was also found between malnutrition and sarcopenia (r = 0.544, p < 0.001). Conclusions: Approximately one-third of patients hospitalized in gastroenterology clinics across Turkey are at risk of malnutrition and sarcopenia. These conditions are particularly associated with malignancy, cirrhosis, and metabolic comorbidities. Our findings highlight the necessity of systematic nutritional and sarcopenia screening upon hospital admission.
