Background: The present study was conducted to estimate gender from 2D:4D ratio and hand morphometry taken from participants by using machine learning (ML) algorithms. Materials and Methods: The study was conducted retrospectively on 88 men and 96 women between the ages of 18 and 30 who did not have any pathology, deformity or surgical interventions on their hands. Hand width (HW), hand length (HL), second digit length (2D), and fourth digit length (4D) of the individuals were measured as the right (R) and left (L) side by using digital calliper and recorded in Excel. In addition, the ratio between the second digit and fourth digit (2D:4D) of each individual was also recorded. Results: As a result of ML modelling, 0.92 accuracy was obtained with Random forest (RF) algorithm. With RF algorithm, all of the 16 women and 18 of the 21 men in the test set were estimated accurately. With SHAP analyzer of RF algorithm, HW-L parameter was found to have the highest contribution in estimating gender. The accuracy rates of the other ML models used in the study were found to vary between 0.78 and 0.89. Conclusions: It was found that 2D:4D ratio and hand morphometry measurements, which are frequently preferred in gender determination, have higher accuracy rate when examined with ML algorithms. In our study, we concluded that using 2D:4D ratio and hand morphometry in estimating gender provides accurate and reliable data. [ABSTRACT FROM AUTHOR]

Objective: Morphological features of the trachea are very important in choosing the correct endotracheal tube size for intubation. In this study, it was proposed to reveal the effect of SARSCoV-2 on tracheobronchial morphology and subcarinal angle. Methods: 56 (26 female, 30 male) COVID-19 and 48 (24 female, 24 male) healthy individuals aged 40 and over were included in the study. The mean age of female patients with COVID-19 was 51.30±12.78 years, while the women in the control group were 45.00±11.89 years. The mean age of male patients with COVID-19 was 48.73±13.99 years, while the mean age of men in the control group was 43.76±8.45 years. The trachea length (TL), proximal, middle and distal levels anteroposterior (AP) and transverse (TR) trachea diameters (TD), subcarinal angle (SA), proximal right main bronchus (RMB) and left main bronchus (LMB) diameters were also measured on computed tomography (CT) images. Results: The RMB angle was higher in men with COVID-19 than in the control group (p=0.005). TL was lower in women with COVID-19 than in the control group (p=0.030). Proximal AP-TD was higher in men with COVID-19 than in the control group (p=0.006). Proximal TR-TD was lower in men with COVID-19 than in the control group (p=0.029). TL, proximal, middle, and distal levels of AP and TR-TD, SA, RMB, and LMB angles, and proximal RMB and LMB diameters were found to be lower in women with COVID-19 than in men with COVID-19 (p=0.001). Conclusions: It was deduced that tracheobronchial morphology might change in patients infected with SARS-CoV-2. It is clinically important that this situation should not be overlooked, especially in the indication of endotracheal intubation. [ABSTRACT FROM AUTHOR]

Somatotype characters have been defined for many diseases. However, there is insufficient information on the somatotype characters of chronic kidney patients. The first aim of our study was to define the specific somatotype in patients diagnosed with CKD. The second aim was to investigate the relationship between somatotype characters and physical activity and depression in CKD patients. A total of 88 (52.7 %) patients diagnosed with CKD between January and December 2021 at the Department of Nephrology, Inonu University Hospital (Malatya, Turkey) and 79 (47.3 %) healthy volunteers were included in the study. Somatotype analysis was performed using the Heath-Carter method. Physical activity was assessed with the International Physical Activity Questionnaire (IPAQ) and depressive symptoms with the Beck Depression Inventory (BDI). Analysis revealed that patients had greater medial calf girth (p = 0.036), higher triceps (p = 0.007) and suprailiac (p = 0.042) skinfold thicknesses and higher body mass index (p = 0.007) compared to controls. Patients also had significantly higher endomorphy (patients: 6.57±1.35 vs. controls: 6.04±1.3; effect size (ES): 0.40, p=0.010) and significantly higher mesomorphy (patients: 7.44±2 vs. controls: 6.85±2.3; ES: 0.27, p=0.039) as well as significantly lower ectomorphy (patients: 0.71±0.69 vs. controls: 1.10±0.93; ES: 0.47, p=0.006). Significant positive correlations were also observed between mesomorphy and IPAQ (rho = 0.219, p = 0.04), endomorphy and BDI (rho = 0.423, p < 0.001) and mesomorphy and BDI (rho = 0.392, p > 0.001). Significant negative correlations were observed between ectomorph and BDI (rho = -0.325, p = 0.002). We observed that the dominant somatotype was endomorphic mesomorph in patients with CKD. In addition, the fact that CKD patients with ectomorphic body structure have lower depressive symptoms could have an impact on their well-being. [ABSTRACT FROM AUTHOR]

A 29-year-old male patient was admitted to the emergency with complaints of fever, nausea, vomiting and abdominal pain. Computed Tomography (CT), demonstrates an enlarged appendix vermiformis with mucosal enhancement represent inflammation. The patient was diagnosed with appendicitis and underwent surgery. In addition, while examining the abdominal CT, a mass was detected incidentally in the supradiaphragmatic area, which was partially included in the images, and contrast-enhanced thoracic CT was applied. We aim to present the patient diagnosed with thymolipoma according to thoracic CT result. Thymolipoma is a rare condition and resection of the lesion and thymus should be performed with video thoracoscopic surgery. [ABSTRACT FROM AUTHOR]
