Alterations in the lipid profile in acne vulgaris patients: A meta-analysis
(SAGE Publications, 2026) Hasan, Md. Mojahidur; Tory, Sehreen; Arslan, Yusuf Kemal; Tutar, Yusuf
Objective Previous studies have reported inconsistent findings regarding alterations in lipid profiles among patients with acne vulgaris (acne). This meta-analysis aimed to resolve these inconsistencies.Methods A systematic search was conducted in Web of Science, Scopus, and PubMed. Lipid profile levels were compared between patients with acne and healthy controls. Mean values and standard deviations for total cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein were used to calculate standardized mean differences with 95% confidence intervals.Results A total of 916 articles were initially identified, of which 38 studies comprising 2485 patients met the eligibility criteria. The pooled analysis demonstrated that patients with acne had significantly higher levels of total cholesterol (pooled standardized mean difference = 0.92, 95% confidence interval: 0.55-1.28), triglycerides (pooled standardized mean difference = 0.82, 95% confidence interval: 0.51-1.14), and low-density lipoprotein (pooled standardized mean difference = 1.52, 95% confidence interval: 1.11-1.92) as well as significantly lower high-density lipoprotein levels (pooled standardized mean difference = -0.45, 95% confidence interval: -0.69 to -0.21). Subgroup and meta-regression analyses were performed to identify the sources of significant heterogeneity. Subgroup analyses further revealed significant alterations in lipid profiles among female patients and in studies conducted in Egypt and Saudi Arabia.Conclusion Alterations in lipid profiles were observed in patients with acne.
Case-based radiology education in interns: comparing learning and retention across modalities
(Galenos Publishing House, 2026) Ataş, İsmail; Yazıcı, Mümin Murat; Hakkani, Doğa; Kekeç, Okan; Sivgin, Ahmet Buğra; Azman, Hayrunnisa; Güler, Enes; Bilir, Özlem
Aim: This study aimed to evaluate intern physicians' ability to interpret basic radiological imaging methods and to investigate the effect of a case-based training program on knowledge acquisition and retention. Materials and Methods: In this prospective study, participants underwent a pre-test before training, a post-test after training, and a retention test four weeks later. Assessments were performed using direct radiography, ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) modalities. The data were statistically analyzed, and performance changes between modalities were examined. Results: This study included 50 intern physicians enrolled in medical school. Of the participants, 40% (n=20) were male and 60% (n=30) were female. The median age was 24 years (interquartile range: 24-24). A statistically significant increase was found in all imaging modalities in the post-test results compared to the pre-test (direct radiography, US, CT: p<0.001; MRI: p=0.019). In the retention test, a statistically significant increase was observed in all modalities compared to the pre-test (p=0.001). However, when the post-test was compared with the retention test, no statistically significant difference was observed in direct radiography and US (p=0.381; p=0.059), while a statistically significant decrease was observed in CT and MRI (p=0.006; p=0.001). Conclusion: Case-based training significantly improves interns' ability to interpret basic radiologic imaging modalities. While permanent learning was achieved primarily in direct radiography and basic US applications, loss of knowledge was observed in more complex modalities such as CT and MRI. Structuring training programs taking into account these differences may contribute to the development of clinical decision-making skills.
Anti-gender normativity and advocacy in Turkey - making a case for practice diffusion
(Routledge Journals, 2026) Tabak, Hüsrev; Bodur Un, Marella
This article offers a practice-oriented perspective on the near-simultaneous rise of anti-genderism in the post-2010 context. Using the Turkish case, it argues that normative isomorphism across different locales is not always the result of recent norm diffusion; their simultaneous and isomorphic emergence can be attributed to the diffusion of practices that enact pre-existing normative frameworks. Empirically speaking, this would mean re-reading the rise of anti-genderism as also a process of practice diffusion, no doubt, within the broader context of the growing influence of right-wing populism and illiberalism. The research suggests focusing on the diffusion of practices rather than norms per se, allowing for a more nuanced understanding of global normative similarities and claims of globality.
Microplastic contamination and ecological risk assessment in two tree frog species (Hyla orientalis and Hyla savignyi) across Turkiye
(2026) Dursun, Cantekin; Demirci, Nagihan; Özdemir, Nurhayat; Gül, Serkan
This study was conducted to investigate the presence of microplastics (MPs) in individuals of Hyla orientalis and Hyla savignyi, two tree frog species naturally distributed in T & uuml;rkiye, to determine the qualitative and quantitative distribution of these particles in their gastrointestinal tracts (GITs) and to analyze their morphological (color, shape, size) and chemical (polymer type) properties in detail. A total of 276 individuals were examined within the scope of the research, 76 of which belonged to H. orientalis and 200 to H. savignyi. A total of 192 microplastic particles were detected in their GITs, and the average size of these particles was determined to be 206.56 +/- 12.88 mu m. The most common microplastic type was PET (67.20%), its shape was fiber (76.00%), and its color was navy blue (25.50%). The highest proportion of microplastic-containing individuals was observed in H. savignyi (56.50%), and microplastic was found in only 11.84% of H. orientalis individuals. No statistically significant difference was found between the two species in terms of polymer type, microplastic shape, and color (p > 0.05). Data obtained from 24 different provinces across T & uuml;rkiye indicate that microplastic contamination has a wide geographical distribution. The highest microplastic amount was recorded from Hatay-Hassa (44 pieces), followed by Kilis and Bitlis provinces. Significant differences were found between provinces in terms of color, shape, and polymer type (p < 0.001). These findings suggest that microplastic pollution is widespread in terrestrial vertebrates and may vary among species and geographic regions, suggesting that amphibians may be important bioindicators for monitoring ecosystem health.
Executive dysfunction and psychological symptoms in problematic social media use
(Turkish Green Crescent Soc, 2026) Kahya, Yalçın; Mavi, Cansu Ünsal; Hocaoğlu, Çiçek
This study aimed to investigate the relationship between problematic social media use (PSMU), executive functions, depression, anxiety, stress, and sleep quality in a healthy adult population. A total of 174 adults (62.6% female, mean age = 37.19 +/- 9.17 years) were recruited online. Participants completed a sociodemographic data form, the Bergen Social Media Addiction Scale (BSMAS), the Executive Function Index (EFI), the Depression Anxiety Stress Scale-21 (DASS-21), and the subjective sleep quality subscale of the Pittsburgh Sleep Quality Index (PSQI). Pearson correlations were conducted. Problematic social media use showed negative associations with executive functioning, particularly with organization (r = -.423, p < .001). In addition, BSMAS scores were positively correlated with depression (r = .354, p < .001), anxiety (r = .217, p < .001), and stress (r = .233, p < .001). The findings indicate that PSMU is strongly linked to executive function and psychological distress. These results highlight the need for interventions targeting cognitive regulation, emotional well-being, and healthy technology use.
