Article 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 PistavBackground 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.Article Citation - WoS: 4Citation - Scopus: 3Assessment of Pulmonary Arterial Hemodynamic and Vascular Changes by Pulmonary Pulse Transit Time in Patients With Human Immunodeficiency Virus Infection(Wolters Kluwer Medknow Publications, 2021) Erdol, Mehmet Akif; Acar, Burak; Ertem, Ahmet Goktug; Karanfil, Mustafa; Yayla, Cagri; Demirtas, Koray; Akcay, Adnan BurakIntroduction: Pulmonary arterial hypertension and human immunodeficiency virus (HIV) infection is a well-known association. Pulmonary pulse transit time (pPTT) is a recent echocardiographic marker that might be used for evaluation of pulmonary arterial stiffness (PAS) in patients with HIV infection. We aimed to investigate whether pPTT elevated in patients with HIV infection compared to healthy controls and its association with echocardiographic indices of right ventricular functions. Materials and Methods: Fifty HIV (+) patients from infectious disease outpatient clinics and fifty age- and sex-matched HIV (-) healthy volunteers were enrolled in this study. pPTT was measured from pulmonary vein flow velocity as the time interval between the R-wave in the electrocardiography and corresponding peak late systolic was then calculated as the mean from two separate pw-Doppler measurements. Results: pPTT, tricuspid annular peak systolic excursion (TAPSE) and right ventricle fractional area change (FAC) were significantly lower in patients with HIV than control patients (177.1 +/- 34.9 vs. 215.7 +/- 35.7 msn, P < 0.001; 2.33 +/- 0.28 vs. 2.19 +/- 0.22, P = 0.039; 45 [4.25] vs. 41.1 [4.0], P = 0.032, respectively). pPTT was positively correlated with FAC, TAPSE and cluster of differentiation 4 count (r = 0.210; P = 0.036, r = 0.256; P = 0.041, r = 0.304; P = 0.044, respectively). Conclusion: Our study showed that pPTT, TAPSE, and right ventricle FAC levels were lower in patients with HIV infection. pPTT is an important predictor in patients with HIV expected to develop pulmonary vascular pathology.Article Citation - WoS: 1Citation - Scopus: 1Utilising Uniportal Video-Assisted Thoracoscopic Surgery for Pericardial Window: A 12-Year Single-Centre Experience in the Diagnosis and Treatment of Pericardial Effusion(Wolters Kluwer Medknow Publications, 2025) Agar, Mehmet; Gulcek, Ilham; Kalkan, Muhammed; Ulutas, Hakki; Celik, Muhammet RehaIntroduction:Uniportal video-assisted thoracoscopic surgery (Uni-VATS) is an effective minimally invasive technique for pericardial drainage, biopsy and window creation in cases of pericardial effusion (PE).Patients and Methods:This retrospective study evaluated 73 patients with PE who underwent pericardial window procedures between 2012 and 2024. Intraoperative and post-operative data related to Uni-VATS were assessed.Results:The mean age of the patients was 53.79 +/- 17.79 years (10-82 years), with 34 (46.6%) females and 39 (53.4%) males. The mean volume of pericardial fluid drained after window creation was 446.23 +/- 199.81 cc (75-1100 cc). The mean operation time was 42.87 +/- 12.79 min, and chest drain removal occurred after an average of 1.8 +/- 1.2 days. The mean duration until discharge or referral to the follow-up clinic was 5.98 +/- 2.14 days. In addition to the pericardial window procedure, pleural biopsy was performed in 12 patients, mediastinal mass biopsy in eight patients and wedge resection for parenchymal nodules in six patients. Microbiologic and virologic cultures of the fluids were negative in all cases. Among the 41 patients with benign cytology, pericardial biopsy results indicated tuberculosis in four patients (5.4%), amyloidosis in one patient (1.3%) and chronic or subacute nonspecific pericarditis in the remaining patients.Conclusion:Uni-VATS is a novel and safe technique that may be the preferred choice for pericardial window due to its diagnostic and therapeutic efficacy, ability to perform simultaneous procedures, favourable impact on operation duration/hospital stay, low complication rates and superiority compared to traditional methods.Article Evaluation of Diaphragmatic Omental Hernias by Radiology: a Prevalence Study(Wolters Kluwer Medknow Publications, 2022) Cankal, Fatih; Demir, Berin T.; Koksal, AliINTRODUCTION: This study aimed to describe the radiological features of omental hernias originating from the diaphragm and their localization on the diaphragm, examine their relationship with the thoracic and abdominal organs, and present guiding data to clinicians in operational planning. MATERIALS AND METHODS: This study was obtained as a result of retrospective scanning of the images of 824 patients aged 18-65 who applied for thorax and/or upper abdomen computerized tomography (CT). The patients' thorax and upper abdomen regions were examined in detail and divided into two groups of individuals with and without hernias. Hernia types, content, localization, and effect types of patients with hernia were recorded and analyzed separately. RESULTS: Diaphragmatic hernia was detected in 197 (23.9%) of 824 patients. While 50.8% of these patients were female, 49.2% were male. Of the patients diagnosed with diaphragmatic hernia, 49.2% (n = 97) had Morgagni hernia, 30.5% (n = 60) had Bochdalek hernia, and 17.8% had hiatal hernia. While Morgagni hernia had anterior localization in 82.5%, Bochdalek hernia was generally localized on the left side (75.8%), and hiatal hernias were sliding type with a rate of 84.2%. The highest effect was observed in Bochdalek hernias (71.1%). Omental tissue (59.4%) was observed most frequently in Morgagni hernias, while stomach content (91.9%) was found to be the highest in hiatal hernias (P < 0.05). DISCUSSION-CONCLUSION: Diaphragmatic omental hernias are rare. The rarity, as well as the uncertain and nonspecific presentations, contributes to the retard in diagnosis. Commonly, the presentation in the adult age group is that of recurrent chest infection and rarely with gastroesophageal reflux and esophagitis. Physicians caring for these patients should be aware of this, and a high index of suspicion is recommended to obviate delay in diagnosis with its associated morbidity. We think the radiological features of diaphragmatic hernias should be detailed in determining and applying the optimal treatment approach. In addition, contrary to what was thought, we found that the prevalence of diaphragmatic hernia in our population is higher than that reported in the literature.Article Citation - WoS: 9Citation - Scopus: 11Using Deep Learning Approaches for Coloring Silicone Maxillofacial Prostheses: a Comparison of Two Approaches(Wolters Kluwer Medknow Publications, 2023) Kurt, Meral; Kurt, Zuhal; Isik, SahinAim: This study aimed to compare the performance of two deep learning algorithms, attention-based gated recurrent unit (GRU), and the artificial neural networks (ANNs) algorithm for coloring silicone maxillofacial prostheses. Settings and Design: This was an in vitro study. Materials and Methods: A total of 21 silicone samples in different colors were produced with four pigments (white, yellow, red, and blue). The color of the samples was measured with a spectrophotometer, then the LFNx01, aFNx01, and bFNx01 values were recorded. The relationship between the LFNx01, aFNx01, and bFNx01 values of each sample and the amount of each pigment in the compound of the same sample was used as the training dataset, entered into each algorithm, and the prediction models were obtained. While generating the prediction model for each sample, the data of the corresponding sample assigned as the target color were excluded. LFNx01, aFNx01, and bFNx01 values of each target sample were entered into the obtained models separately, and recipes indicating the ratios for mixing the four pigments were predicted. The mean absolute error (MAE) and root mean square error (RMSE) values between the original recipe used in the production of each silicone and the recipe created by both prediction models for the same silicone were calculated. Statistical Analysis Used: Data were analyzed with the Student t-test (alpha=0.05). Results: The mean RMSE values and MAE values for the ANN algorithm (0.029 & PLUSMN; 0.0152 and 0.045 & PLUSMN; 0.0235, respectively) were found significantly higher than the attention-based GRU model (0.001 & PLUSMN; 0.0005 and 0.002 & PLUSMN; 0.0008, respectively) (P < 0.001). Conclusions: Attention-based GRU model provided better performance than the ANN algorithm with respect to the MAE and RMSE values.
