Calcium Phosphate Honeycomb Scaffolds With Tailored Microporous Walls Using Phase Separation-Assisted Digital Light Processing
(MDPI, 2025) Kim, Gyu-Nam; Park, Jae-Hyung; Song, Jae-Uk; Koh, Young-Hag; Park, Jongee
The present study reports on the manufacturing of biphasic calcium phosphate (BCP) honeycomb scaffolds with tailored microporous walls using phase separation-assisted digital light processing (PS-DLP). To create micropores in BCP walls, camphene was used as the pore-forming agent for preparing BCP suspensions, since it could be completely dissolved in photopolymerizable monomers composed of triethylene glycol dimethacrylate (TEGDMA) and polyethylene glycol diacrylate (PEGDA) and then undergo phase separation when placed at 5 degrees C. Therefore, solid camphene crystals could be formed in phase-separated BCP layers and then readily removed via sublimation after the photopolymerization of monomer networks embedding BCP particles by DLP. This approach allowed for tight control over the microporosity of BCP walls by adjusting the camphene content. As the camphene content increased from 40 to 60 vol%, the microporosity increased from similar to 38 to similar to 59 vol%. Consequently, the overall porosity of dual-scale porosity scaffolds increased from similar to 51 to similar to 67 vol%, while their compressive strength decreased from similar to 70.4 to similar to 13.7 MPa. The mass transport ability increased remarkably with an increase in microporosity.

Assessment of Anticancer Effects of Aloe Vera on 3D Liver Tumor Spheroids in a Microfluidic Platform
(Wiley, 2025) Tevlek, Atakan; Kibar, Gunes; Cetin, Barbaros
The search for effective anticancer therapies has increasingly focused on natural compounds like Aloe vera, renowned for its therapeutic properties. This study investigates the anticancer properties of Aloe vera on 3D liver tumor spheroids via a PDMS-based microfluidic device, providing a more physiologically realistic model compared to traditional 2D cultures. HepG2 cells were cultivated to generate 3D spheroids on-chip, thereafter subjected to different concentrations of Aloe vera and the chemotherapeutic drug Doxorubicin to evaluate cytotoxic effects. The microfluidic system, validated by COMSOL simulations, facilitated continuous perfusion and real-time assessment of cell viability over a duration of 10 days. The results indicated that Aloe vera markedly diminished cell viability by triggering apoptosis at concentrations over 12.5 mg/mL. IC50 values were determined at 72 h: 25 +/- 0.10 mg/mL for Aloe vera and 5.47 +/- 0.03 mu g/mL for Doxorubicin in 2D cultures, but in 3D cultures, the IC50 values were 31.25 +/- 0.14 mg/mL for Aloe vera and 8.33 +/- 0.05 mu g/mL for Doxorubicin. This study underscores the promise of Aloe vera as a natural anticancer agent and illustrates the efficacy of microfluidic platforms for enhanced drug screening and customized medicine applications.

(Springer London Ltd, 2025) Emral, Ahmet Cihangir; Yazici, Sinan Efe
PurposePilonidal sinus disease (PD) is a chronic, recurrent inflammatory condition primarily affecting the sacrococcygeal region, often resulting in discomfort, abscess formation, and recurrent disease. Various surgical interventions, including laser ablation, have been employed to treat recurrent PD. This study evaluates the efficacy of laser ablation in patients with recurrent PD, focusing on treatment success, recurrence rates, complications, and recovery outcomes.MethodsA retrospective analysis of 37 patients with recurrent pilonidal sinus disease treated with laser ablation between January 2022 and January 2025 was conducted. Preoperative data, postoperative complications, healing time, Visual Analog Scale values, and return to normal activities were collected.ResultsThe results showed that 70.3% of patients achieved complete healing without recurrence, while 21.6% experienced recurrence within a mean follow-up of 9.6 months. Five patients (13.5%) developed superficial infections, which were managed with local dressing. The median time for wound healing was 35 days, and patients returned to normal activities in an median of 1 day. Persistent disease was observed in 8 patients (21.6%), of whom 5 patients (62.5%) achieved full epithelialization after retreatment with laser ablation.ConclusionThe ease of application, avoidance of hospitalization, minimal postoperative care, and rapid return to daily activities make laser treatment a safe and effective therapeutic option for patients with recurrent pilonidal disease, supported by favorable outcomes and low morbidity.

Ongoing Discussion: Is Prophylactic Central Neck Dissection Necessary in Ct1a-B,2n0 Papillary Thyroid Cancer
(Sage Publications Ltd, 2025) Bayir, Omer; Akan, Latif; Kizilgul, Muhammed; Ucan, Bekir; Karahan, Sevilay; Toptas, Gokhan; Korkmaz, Mehmet Hakan
Objective: To analyze the central lymph node metastasis (CLNM) rates of patients who underwent prophylactic central lymph node dissection (pCLND) with total thyroidectomy for cT1-2N0 papillary thyroid cancer in our clinic, to evaluate the conditions associated with lymph node metastasis, and to examine the necessity of pCLND in these patient groups.Methods: This study includes a retrospective review of the medical data of patients who underwent bilateral/unilateral central lymph node dissection (CLND) (b/uCLND) with total thyroidectomy in our center between 2013 and 2021, whose fine needle aspiration biopsy result was reported as malignant, who were detected as cT1a-1b-2N0 on thyroid and neck ultrasonography.Results: Of the 251 patients included in the study, 63 (25%) had CLNM (49 (19.5%) ipsilateral and 14 (5.5%) had contralateral CLNM). Twenty-two (20.1%) of 109 patients with cT1a, 30 (28.3%) of 106 patients with cT1b, and 11 (30.5%) of 36 patients with cT2 had CLNM, and metastasis rates increased with increasing cT category. CLNM rates increased with increasing pT category (p=0.005). CLNM was present in 21 (38.8%) of 54 patients (21.5%) with collision tumors, and metastasis rates increased significantly compared to the presence of a single histopathologic tumor (p=0.006). CLNM rates were higher in patients with multicentric tumor localization than in those with unicentric localization (p=0.006).Conclusion: Multicentricity, bilaterality, capsule invasion, collision tumors and tumors larger than 1 cm increase the risk of CLNM. uCLND for tumors larger than 1 cm, bCLND for tumors larger than 2 cm can be considered. We believe that patients with unilateral CLNM also have an increased risk of contralateral metastasis.

Biosorption of Reactive Dyes by Novel Bacterium Leclercia Adecarboxylata: Complete Removal of Reactive Black 5 and Molecular Insights Into the Adsorption Mechanism
(Wiley, 2025) Sen, Seda; Korkmaz, Filiz; Kilic, Nur Kocberber
Leclercia adecarboxylata isolated from the D & uuml;den Waterfall (Turkey) was utilized as a biosorbent for the removal of Reactive Black 5 (RB5), Setazol Blue BRF-X (BRF-X), Setazol Navy Blue SBG (SNB), and Setazol Turquoise Blue G (STBG). Of the dyes, RB5 was removed with the highest efficiency, 97.4% after 60 min. The effect of parameters such as pH (3-9), initial biosorbent dose (0.1-2.0 g/L), and initial dye concentration (25-1200 mg/L) on the biosorption of RB5 was investigated. Increasing the biosorbent dosage from 0.1 to 2.0 g/L enhanced the RB5 removal from 55.3% to 100% within 10 min. The complete removal (100%) of RB5 was achieved in media with 2.0 g/L biosorbent and 25 mg/L RB5 at pH 3 after 10 min. Additionally, the soluble extracellular polymeric substances (EPS) of L. adecarboxylata were found to consist of proteins, lipids, nucleic acids, and polysaccharides according to Fourier transform infrared spectroscopy (FTIR) analysis. The EPS was found to play a crucial role in dye removal, forming chemical interactions with dye molecules. Zeta potential analysis was used to evaluate the charge distribution on the biosorbent surface (-12.6 +/- 1.1 mV) and its interactions in the biosorption process. Kinetic and isotherm models suggested a complex interaction mechanism between the biomass and the dye. Adsorption isotherm data were analyzed via nine isotherm models. Among them, the Hill model was found to be the best fit for describing the equilibrium adsorption process of the RB5 (R2 = 0.9993). Overall, the applied models elucidated the influence of both physical and chemical interactions on the mechanism. Kinetic studies revealed that the adsorption of RB5 fit a pseudo-second-order kinetic model. The unique biochemical composition of the indigenous L. adecarboxylata biosorbent provided a high affinity for RB5, offering a sustainable, rapid, and economical solution for the treatment of dye-polluted water.

Incidental Detection of Ectopic Liver Tissue During Elective Cholecystectomy: a Case Report
(Frontiers Media Sa, 2025) Emral, Ahmet Cihangir
Introduction Ectopic liver tissue (ELT) is a rare embryological anomaly most commonly found in the abdominal region, particularly on the gallbladder. It is generally asymptomatic and is often discovered incidentally during surgery or autopsy. Although histologically similar to the main liver, ELT should be excised due to the potential risk of malignancy.Case presentation This study presents a case of incidental ELT discovered during elective cholecystectomy in a 34-year-old female patient. Preoperative imaging revealed multiple gallstones, and during laparoscopic exploration, an ectopic liver tissue lesion was found on the gallbladder fundus. The lesion, measuring 10 x 5 mm, was excised en bloc with the gallbladder and sent for pathological examination, which showed no malignancy.Discussion The rarity and asymptomatic nature of ELT make it difficult to diagnose preoperatively, but its association with malignant transformation warrants careful management. In cases of suspected malignancy, further surgical approaches such as extended surgical margins and regional lymph node dissection should be considered.Conclusion This case underscores the importance of early detection and excision of ectopic liver tissue due to its potential for malignant transformation.

Development of a Questionnaire To Assess Phosphate Knowledge in Children With Chronic Kidney Disease and Their Caregivers
(John Wiley and Sons Inc, 2025) McAlister, L.; Shaw, V.; Pugh, P.; Joyce, T.; Snauwaert, E.; Bathgate, F.; Lambert, K.
Introduction: Hyperphosphataemia is a common complication of paediatric chronic kidney disease (CKD), despite the use of phosphate binders and the numerous strategies employed to reduce dietary phosphate (P) intake. This article describes the development of two self-administered semi-structured Phosphate Understanding and Knowledge Assessment (PUKA) questionnaires. The purpose of these is to assess challenges with adherence and measure declarative nutrition and procedural knowledge of phosphate in children and young people (CYP) with CKD and their caregivers. The aim is to create questionnaires that will be used for future studies investigating the relationship between knowledge and blood P-levels. Methods: Questions were generated from a literature review, clinical experience and feedback from a survey sent to UK paediatric kidney dietitians. The content, format and style of the questions were adapted and validated via expert consensus (including a psychologist, play therapist, paediatric kidney dietitians and nephrologists from the international Paediatric Renal Nutrition Taskforce, and our Young Persons’ Advisory Group), two caregivers and two CYP. A draft questionnaire was piloted with five caregivers and CYP with CKD to ensure face and content validity. To allow utilisation in a planned multi-centre trial, it was translated into five languages (Dutch, French, German, Italian and Turkish). The final English version questionnaires were used in a sample of CYP with CKD stages 4–5 and on dialysis (CKD4-5D), and caregivers, from three UK paediatric kidney centres. Results: From an initial pool of 80 questions, 37 were included in the final PUKA questionnaire. Thirteen were knowledge-based, and a knowledge score was developed. An adult and a child-friendly format were designed. Pilot testing confirmed face validity to ensure the questions were understandable. Forty-four CYP with CKD4-5D and 33 caregivers completed the final English PUKA questionnaires, with over 80% rating it easy to complete. The median time required to complete it was 11:06 min (IQR: 7:22–16:31). Conclusions: The PUKA questionnaires are a valid and reliable tool for measuring P-related knowledge and experiences of managing phosphate in CYP with CKD and their caregivers. © 2025 The British Dietetic Association Ltd.

Outcomes of Gonioscopy-Assisted Transluminal Trabeculotomy in Children With Early-Onset Glaucoma Secondary To Sturge–weber Syndrome
(American Academy of Ophthalmology, 2025) Aktas, Z.; El Sayed, Y.; Ucgul, A.Y.; Gawdat, G.; Elhilali, H.; Aboalazayem, F.
Purpose: To evaluate the effectiveness and safety of gonioscopy-assisted transluminal trabeculotomy (GATT) in managing early-onset glaucoma secondary to Sturge–Weber syndrome (SWS). Design: A retrospective interventional case series. Participants: Medical records of 16 patients (22 eyes) diagnosed with early-onset glaucoma secondary to SWS who underwent GATT surgery were reviewed. Methods: All patients underwent GATT surgery using a 5-0 or 6-0 prolene suture under general anesthesia. Main Outcome Measures: The primary outcomes were intraocular pressure (IOP) reduction, complete surgical success (IOP ≤ 18 mmHg without medications), qualified surgical success (IOP ≤ 18 mmHg with medications), and postoperative complications. Results: The mean IOP decreased significantly from 25.4 ± 4.8 mmHg at baseline to 15.7 ± 4.2 mmHg at the final follow-up (P < 0.001), representing a 38.19% reduction. The mean age at the time of GATT surgery was 33.6 ± 33.9 months. The mean follow-up duration was 16.3 ± 6.4 months. Complete surgical success was achieved in 45.4% of eyes (10 out of 22), while qualified success was reached in 81.8% of eyes (18 out of 22). Despite the overall success, 18.1% of eyes (4 eyes) required additional surgical interventions during the follow-up period. These included Ahmed glaucoma valve implantation in 1 eye, trabeculectomy in 2 eyes, and transscleral diode laser cyclophotocoagulation in 1 eye. Transient hyphema was the only reported complication, resolving spontaneously within 1 week without further intervention. Conclusions: Gonioscopy-assisted transluminal trabeculotomy appears to be a promising surgical option for managing early-onset glaucoma in patients with SWS, offering significant IOP reduction and a favorable safety profile within the limitations of our study. However, further studies with longer follow-up periods and comparative groups are necessary to confirm these findings.

(Frontiers Media Sa, 2025) Ozturk, Hakki; Ozsoy, Metin; Tuna, Aysegul; Varlibas, Artuner; Cesur, Salih; Aksoy, Altan; Demir, Mehmet Emin
Background: Hemodialysis patients are at increased risk for hepatitis E virus (HEV) infection due to their immunocompromised status and frequent exposure to invasive medical procedures. HEV can lead to chronic infections and severe complications, particularly in high-risk populations. This study aimed to determine HEV-IgG seroprevalence among hemodialysis patients in Ankara, Turkey, and evaluate associated risk factors. Methods: A total of 160 hemodialysis patients from three private dialysis centers in Ankara were included in this prospective, cross-sectional study. Anti-HEV-IgG antibodies were detected using the ELISA method. Demographic characteristics and potential risk factors, including dialysis duration, comorbidities, blood transfusion history, drinking water source, dietary habits, and involvement in animal husbandry, were assessed via structured surveys. Statistical analyses were conducted using SPSS Version 22.0, with Pearson's chi-square and Fisher's exact tests applied to categorical variables. Logistic regression analysis was performed to identify independent risk factors for HEV seropositivity. Results: HEV-IgG seropositivity was detected in 42 patients (26.25%). Seroprevalence increased significantly with age, rising from 6.7% in patients under 55 years to 47.4% in those over 65 years (p < 0.001). Extended dialysis duration (>5 years) was also significantly associated with HEV seropositivity (p = 0.02). However, no significant associations were found between HEV seropositivity and gender, blood transfusion history, source of drinking water, consumption of raw meat, or involvement in animal husbandry (p > 0.05). Conclusion: The HEV-IgG seroprevalence among hemodialysis patients in Ankara was higher than previously reported rates in Turkey. Age and prolonged dialysis duration emerged as significant risk factors, underscoring the importance of screening and preventive strategies in this vulnerable population. Further multi-regional studies are needed to better understand HEV transmission dynamics and improve management strategies in hemodialysis patients.

Mapping the Anterolateral Ligament of the Knee: a Bibliometric Analysis
(Springernature, 2025) Oktem, Hale; Jamil, Yusuf; Sever, Sinem Nur; Basic Sciences
BackgroundThis study aims to evaluate research trends, key contributors, and thematic focuses in research of the anterolateral ligament (ALL) of the knee. It seeks to identify future direction for studies related to long-term clinical outcomes regarding ALL's role in rotational stability, especially in the context of anterior cruciate ligament (ACL) injuries.MethodsA bibliometric analysis was conducted using the Web of Science (WoS) database, covering publications from 2012 to 2024 with the search term "anterolateral ligament". A total of 942 studies were identified. Descriptive statistics summarized publication trends, authorship, institutional contributions, and citation metrics. VOSviewer software was used to analyze co-authorship network analysis, keyword co-occurrence mapping, and total citation analysis. Yearly publication and citation trends were analyzed using WoS data. Studies addressing the ALL in other body regions were excluded. Additionally, only authors with at least one publication and one citation were considered, and documents with more than 25 authors were excluded. A total citation analysis was conducted, and 24 relevant keywords with more than 5 occurrences were identified using VOSviewer.ResultsAmong 942 publications, 707 were original articles. Research output peaked in 2017 (125 articles). Sonnery-Cottet was the leading author (75 publications), while Universidade De S & atilde;o-Paulo emerged as the top institution (57 publications). Key journals included Arthroscopy: Journal of Arthroscopic and Related Surgery (143 articles) and The American Journal of Sports Medicine (131 articles). Keywords such as "anterior cruciate ligament", "reconstruction", and "rotational stability" dominated, reflecting a focus on ACL injury management. The top ten cited studies accrued 3,86 citations, with Claes et al.'s anatomical study leading (621 citations). Of the 942 ALL-related articles in WoS, 381 focused on anatomy (11,278 citations) while 814 addressed reconstruction (17,048 citations). Keyword trends shifted from anatomical to clinical terms, with anatomy declining and stability, injury, and outcomes gaining prominence from 2021 to 2024.ConclusionsThis bibliometric analysis underscores the growing interest in ALL research, peaking between 2016 and 2017. While foundational studies on ALL anatomy and biomechanics appear saturated, future research should prioritize clinical outcomes in terms of failure rate, reoperation, the long-term efficacy of ACL-ALL reconstruction, and advancements in imaging techniques.

Validity and Reliability of Turkish Version of the Physical Activity Enjoyment Scale-8 Items in Adults
(Sage Publications inc, 2025) Cinar-Medeni, Ozge; Incekas, Caner; Ozcan, Aysenur; Ozdemir, Furkan; Ulusoy, Burak; Can-Karahan, Zehra
Background: The enjoyment of physical activity significantly influences participation in sports and various forms of physical activity. This study aims to conduct a cross-cultural adaptation and assess the reliability and validity of the Turkish version of the Physical Activity Enjoyment Scale-8 Items (PACES-8). Methods: A total of 120 participants were included in the study. A standardized translation process was followed. Criterion-related validity was assessed using the Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2) and the International Physical Activity Questionnaire-Short Form (IPAQ). All participants were evaluated in two sessions following a 15-min walk. Sociodemographic data, PACES-8, BREQ-2, and IPAQ questionnaires were administered during the initial measurement, while the second measurement focused solely on assessing physical activity enjoyment. Results: Exploratory factor analysis revealed factor loadings ranging from 0.78 to 0.94, indicating a strong single-factor structure. The model demonstrated a good fit to the data (Chi-Square Goodness of Fit Test (chi(2)/df) = 3.26, p < 0.001; Comparative Fit Index = 0.96; Tucker-Lewis Index = 0.93). The Cronbach's alpha coefficient was 0.95, reflecting excellent internal consistency. PACES-8 showed a low correlation with the external regulation score of BREQ-2 (r = -0.24, p = 0.03) and the physical activity score (IPAQ score) of participants (r = 0.24, p = 0.007). Conclusions: The findings suggest that the Turkish version of PACES-8 is a unidimensional, reliable, and valid instrument for measuring enjoyment of physical activity. Further research is needed to assess its validity across different populations.

BackgroundFood fraud and adulteration pose critical global challenges impacting economic stability and public health. This study examines the prevalence and characteristics of food fraud incidents in Turkey, an international player in the food supply chain. Controls carried out from production to consumption reveal many fraudulent events worldwide.ResultsData collected by the Ministry of Agriculture and Forestry of T & uuml;rkiye from 2012 to 2022, covering 4007 incidents and 7180 specific cases of adulteration, form the basis of this analysis. The study categorizes food fraud by region, product group and type of fraud, revealing trends and patterns. Key findings indicate a higher incidence of fraud in milk, meat and vegetable oil products, including the detection of drug-based adulteration having potential for serious health consequences.ConclusionAt most importance, we demonstrated the importance of risk-based food inspections and the development of new detection technologies to enhance food safety. The results are fundamental for more effective food inspections in terms of risk-based conformity assessment approaches or developing new methods, devices and analysis kits in terms of scientific and technological approaches. Still, they can also significantly improve future food safety measures. These insights are aimed at informing global food safety strategies and policymaking, contributing to a safer and more transparent food supply chain. (c) 2025 The Author(s).

Caval Valve Implantation Procedure in 7 Cases of Torrential Tricuspid Regurgitation and Step-By Description of the Procedure
(Kare Publ, 2025) Bozbas, Huseyin; Barcin, Cem; Asfour, Mohamed; Celebi, Savas A.; Cam, Ersin; Ilkay, Erdogan
Tricuspid regurgitation (TR) is an increasingly prevalent and clinically significant health problem.1 Due to the growing understanding of the importance of TR, the tricuspid valve has transitioned from being a forgotten valve to one of significant concern. Tricuspid regurgitation is often functional, and as it progresses to moderate or severe stages, hospital admissions increase and prognosis worsens.1,2 There are no effective pharmacological treatments for TR, and the 5-year survival rate with medical management is reported to be less than 50%.3 Therefore, early diagnosis and timely intervention for TR is crucial. Both surgical and percutaneous treatment options are available for severe TR. The mortality rate for isolated TR surgery is generally high.4 In recent years, transcatheter treatments have become feasible for this patient group, and accumulating evidence shows that transcatheter treatment is superior to medical management.5,6 Transcatheter interventions for TR can be performed in 4 ways, 2 involving repair and 2 involving valve We aimed to present our experience with transcatheter caval valve implantation (CAVI) in 7 patients with torrential TR who were not suitable for surgical intervention or transcatheter edge-to-edge repair (T-TEER) due to severe coaptation defects, review the current literature, and provide a step-by-step description of the procedure.

The Role of a Smartphone Application in Monitoring the Risk of Hearing Loss Associated With Personal Listening Devices in Young Adults
(Wolters Kluwer Medknow Publications, 2025) Tuz, Deniz; Saricamlik, Selin; Bodur, Ceren; Kirazli, Gulce; Akmese, Pelin Pistav
Background Exposure to loud music has been reported to affect high-frequency hearing thresholds in adults. This study aimed to use a mobile application to assess the risk of hearing loss associated with personal listening devices (PLDs) in young adults. Methods A cross-sectional study was conducted on 99 healthy iPhone Operating System (iOS) smartphone users aged 17 to 31 years. Based on their weekly, monthly, 6-month, and annual listening data from the "Health" application, participants were classified into at-risk or non-risk groups. Six individuals in the at-risk group underwent audiological assessments. The Speech, Spatial, and Qualities of Hearing Scale (SSQ) was given to all participants. SSQ scores were compared between groups using the Mann-Whitney U test. The correlation between average PLD sound levels and SSQ scores was analyzed using the Spearman's test. Results The weekly, monthly, 6-month, and annual listening data showed that 16, 14, 12, and 12 participants were at risk, respectively. All six participants who underwent audiological assessment exhibited normal hearing thresholds. However, a pattern of decline at high frequencies was noted. A significant difference was found between the groups in terms of overall SSQ score (z = -2.74, P = 0.00), speech perception score (z = -3.25, P = 0.00), and hearing quality score (z = -2.01, P = 0.04) based on the 6-month and annual listening data. A weak positive correlation was found between the SSQ scores across all subscales and monthly sound-level data. Exposure duration was negatively correlated with speech perception (r = -0.32, P < 0.05), spatial perception (r = -0.26, P < 0.05), and overall score (r = -0.29, P < 0.05) in weekly data, as well as with hearing quality (r = -0.21; P < 0.05) and overall score (r = -0.21, P < 0.05) in annual data. Conclusions The immediate effects of loud music exposure were absent; however, prolonged exposure resulted in reduced speech perception and hearing-quality levels. Data from the iOS "Health" application indicated that some individuals were at risk of hearing loss, suggesting the need to modify their listening habits to prevent long-term decline in hearing function.

Epidemiological Assessment of Depression, Activities of Daily Living and Associated Factors in Elderly Individuals Aged 65 Years and Older: Evidence From a Population-Based Study
(Mdpi, 2025) Arayici, Mehmet Emin; Kose, Ali; Dolu, Suleyman; Arayici, Sema Gultekin; Gedik, Gizem; Kilic, Beyza Nur; Erkin, Ozum
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 T & uuml;rkiye. 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 T & uuml;rkiye, 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 and Objectives: Non-intubated uniportal video-assisted thoracoscopic surgery (NI-UniVATS) is a minimally invasive technique performed using a single port, allowing the entire surgical procedure to be completed with spontaneous breathing without the need for general anesthesia. Materials and Methods: This retrospective study included 51 patients who underwent NI-UniVATS between 2020 and 2023. The intraoperative and postoperative data of patients who underwent NI-UniVATS were evaluated. Results: Among the cases, 37 (72.5%) were male, and 14 (46.6%) were female, with a mean age of 47.73 +/- 20.43 years (range: 18-78 years). The mean operative time was 25.92 +/- 7.31 min. No perioperative complications were observed in any patient. The mean postoperative hospital stay was 4.17 +/- 1.76 days (range: 2-9 days). A right hemithoracic approach was performed in 28 patients (54.9%), whereas a left hemithoracic approach was used in 23 patients (45.1%). The procedures performed included wedge resection in 27 patients (52.9%), biopsy in 22 patients (43.1%), pericardial window creation in one patient (2%), and intrathoracic foreign body removal in one patient (2%). Conclusions: NI-UniVATS allows for safer surgery by preventing the adverse effects and complications associated with general anesthesia. NI-UniVATS can be recommended as a safe and feasible approach for both minor and major thoracic procedures.

The Association Between Digital Device Usage Behaviors and the Incidence of De Quervain’s Tenosynovitis Among University Students
(Taylor and Francis Ltd., 2025) Jamil, Y.; Öktem, H.; Sever, S.N.; Basic Sciences
Background: The extensive use of mobile and digital devices has been implicated in various musculoskeletal disorders, including de Quervain’s tenosynovitis (dQD), a condition affecting the thumb. Purpose: The present study investigates the relationship between digital device usage patterns and the prevalence of dQD among university students. Methods: A cross-sectional study was conducted with 508 participants (255 females and 253 males), collecting data on daily device use time, wrist positions, hand dominance, and stretching practices via a questionnaire. Data collection was carried out through a supervised, face-to-face survey. Diagnosis of dQD was determined using Finkelstein’s test, all data were analyzed using SPSS software. Results: Out of 508 participants, 187 (36.8%) tested positive for dQD, with 152 (95.6)% occurring in the dominant hand (p =.006, Cramér’s (Formula presented.) = 0.121). 250 participants used their devices with wrists in ulnar deviation (49.2%), which was strongly linked to a positive Finkelstein test result (p =.004, Cramér’s (Formula presented.) = 0.175). Finkelstein’s test showed increasing positivity with device use, ranging from 12.5% for < 2 hours to 46.2% for ≥ 8 hours, with a statistically significant association (p <.001, Cramér’s (Formula presented.) = 0.234). Device usage varied, with the highest test positivity rates among those using devices 6–8 hours per day suggesting a significant association with dQD (p =.001). No significant relationship was found between dQD and the practice of stretching or relieving movements (p =.146). Conclusion: The findings indicate that prolonged digital device usage, specific wrist positions such as ulnar deviation, and dominant-hand use are significantly associated with an increased risk of de Quervain’s tenosynovitis among college students. © 2025 Taylor & Francis Group, LLC.

Chemical Mechanical Polishing as an Alternative Surface Treatment Technique for Corrosion Prevention of Carbon Steel in an Acidic Medium
(Nature Portfolio, 2025) Ahmed, Mohamed; Ali Al-Timimi, Buthainah; Al-Ali, Maha; Abdullah, Ghassan H.; Khalaf Atiyaha, Safa; Yaseen Ali Aljanabi, Ahmed; Mel, Maizirwan
Chemical mechanical polishing (CMP) has been a standard technique in semiconductor manufacturing for achieving smooth surfaces. CMP utilizes a synergistic interplay of chemical and mechanical interactions to achieve the desired removal rates, selectivity, and ultimately planarity with different substrate materials. In this study, the impact of CMP on the surface properties of steel used in the petroleum industry was examined, with a focus on its corrosion behavior posttreatment. Steel samples were subjected to CMP with and without an oxidizer in a silica-based slurry, and their surface characteristics were compared to those of samples polished mechanically. The addition of an oxidizer to the slurry resulted in increased material removal rates and the formation of an oxide layer on the surface; this phenomenon was not observed in CMP without an oxidizer. However, in mechanical polishing, the action of silicon carbide grains on the steel surface led to an increase in the removal rate but caused a decrease in its corrosion resistance. Compared with other treatments, the oxide layer provided a good protective barrier against corrosion and improved the corrosion resistance of the steel substrate. Based on the results from the practical study, an improvement in the corrosion resistance properties was observed due to the chemical reaction of the oxidizer and the mechanical action of the silica nanoparticles; these results showed the importance of chemical mechanical polishing as an alternative method to reduce the corrosion of steel in acidic environments. Additionally, the effect of hydrogen peroxide in a silica slurry with respect to the wettability, surface roughness, and hardness of steel was examined using contact angle measurements, profilometry, scanning electron microscopy, and microhardness tests.

(Sage Publications inc, 2025) Ulug, Naime; Kodak, Seyde Busra; Kodak, Muhammed Ihsan; Karahan, Zehra Can; Kilic, Erden
Background: COVID-19 might have a negative impact on sports performance. There are few studies in the literature that assess how the sports performance of adolescent athletes is affected by COVID-19. Objective: This study aimed to compare the sports performance of adolescent overhead athletes who had COVID-19 infection with those who had not. Methods: The study involved adolescent elite overhead athletes from basketball, volleyball, handball, and tennis. Athletes' performance were assessed using core muscle endurance, hand grip strength, upper extremity functional performance, reaction time and agility performance, and the 3-min step test. Results: Study included 47 adolescent overhead athletes (mean age 15.15 +/- 1.51 years). The COVID-19 group showed significantly higher Borg Scale scores and decrease in oxygen saturation levels only after the step test (p = 0.02, p = 0.02, respectively). Additionally, COVID-19 group had lower grip strength in both right and left hands compared to the non-COVID group (p = 0.01, p = 0.05, respectively). No significant association was found between core muscle power and endurance, upper extremity functional performance, reaction time and agility performance (p > 0.05). Conclusions: Our results showed reduced hand grip strength and increased fatigue following COVID-19 infection in adolescent overhead athletes. Time period after COVID-19 infection had a negative correlation with sports performance and core endurance.
