The aim of this study is to test whether sex prediction can be made by using machine learning algorithms (ML) with parameters taken from computerized tomography (CT) images of cranium and mandible skeleton which are known to be dimorphic. CT images of the cranium skeletons of 150 men and 150 women were included in the study. 25 parameters determined were tested with different ML algorithms. Accuracy (Acc), Specificity (Spe), Sensitivity (Sen), F1 score (F1), Matthews correlation coefficient (Mcc) values were included as performance criteria and Minitab 17 package program was used in descriptive statistical analyses. p ≤ 0.05 value was considered as statistically significant. In ML algorithms, the highest prediction was found with 0.90 Acc, 0.80 Mcc, 0.90 Spe, 0.90 Sen, 0.90 F1 values as a result of LR algorithms. As a result of confusion matrix, it was found that 27 of 30 males and 27 of 30 females were predicted correctly. Acc ratios of other MLs were found to be between 0.81 and 0.88. It has been concluded that the LR algorithm to be applied to the parameters obtained from CT images of the cranium skeleton will predict sex with high accuracy.
Objectives This study aims to investigate the effectiveness of scapular stabilization exercises in patients with chronic neck pain and scapular dyskinesis. Patients and methods This single-center, prospective study included a total of 36 patients (17 males, 19 females; mean age: 41±12.8 years; range, 25 to 57 years) with chronic neck pain and scapular dyskinesis between April 2018 and September 2018. The patients were randomly assigned to three treatment groups. Group 1 (n=13) consisted of those receiving scapular stabilization exercises by a physiotherapy specialist control in addition to the routine physiotherapy and rehabilitation program; Group 2 (n=12) consisted of those receiving the routine physiotherapy and rehabilitation program in addition to scapular stabilization exercises in-home training program; and Group 3 (n=11) consisted of those receiving the routine physiotherapy and rehabilitation program alone. The assessments were made using the Visual Analog Scale (VAS) and Northwick Park Neck Pain Questionnaire (NPQ). Results Significant differences were found in the pre- and post-treatment VAS scores, and Group 1 and Group 2 created this significant difference (p<0.05). A significant difference was also observed in the pre- and post-treatment NPQ scores among the groups (p<0.05). Group 1 showed the most significant improvement of the NPQ scores (p<0.05). Conclusion Our study results suggest that addition of scapular stabilization exercises to the routine physiotherapy components may be an effective method for improving pain and functional results.
We are experiencing the effects of Covid-19 pandemic as the whole world. All educational facilities have been negatively affected within this period. In this study, the aim was to evaluate online Anatomy education during Covid-19 pandemic with students' feedbacks and it was questioned whether it would be efficient to use online education more actively in the following years. Methods: A total of 1127 first and second year students from Dentistry Faculty and Medicine Faculty of Düzce, Karabük and İnönü Universities were included in the study. The survey prepared in "Google Forms" was sent online to students via "WhatsApp" application. Descriptive statistical analyses were used in data. Results: According to analysis results, it was found that the students agreed on the content and efficiency of online anatomy education, not having learning difficulties, the layout of the lessons, the importance of the lesson, the necessity for their profession, the importance of visual tools, they are worried about not being able to do face-to-face lessons, and anatomy theoretical courses shouldn't be taught online when the pandemics is over. It was found that medicine faculty students placed more importance on anatomy education in terms of professional aspects. Conclusions: As a result, we believe that the online Anatomy education students receive is important in terms of their professional development. However, we believe that it won't be possible for online Anatomy education to replace face-to-face education. This study will be a resource for studies to be conducted in medicine and health sciences fields in terms of online education.
Background: The aim of this study was to compare the anthropometric and cone beam computed tomography (CBCT) measurements taken from risk-free and risky groups by using the modified Mallampati score (MMS). Patients and Methods: A total of 176 volunteers between the ages of 18 and 65 in four different MMS classes were included in the study. The patients in classes MMS I and MMS II were accepted as risk-free and the patients in classes MMS III and MMS IV were accepted as risky for intubation. The Mann–Whitney U test was performed on the data to compare the anthropometric and radiological measurements taken from the risk-free and risky groups. A receiver operating characteristic (ROC) analysis was applied to the parameters that had a statistically significant difference. Results: According to the analysis results, statistically significant differences were found in the neck circumference (NC), maximum interincisal distance (MID), thyromental distance (TMD) and sternomental distance (SMD) of the anthropometric measurements of men and women between the risk-free and risky groups (P < 0.05). In terms of CBCT measurements, the thickness of the tongue (TT), distance between the uvula and posterior wall of pharynx (U-Ph), distance between posterior nasal spine and nasopharynx (Snp-Nph) and length of the epiglottis (LE) were found to have statistically significant differences between the risk-free and risky groups of men and women (P < 0.05). Conclusion: The NC, MID, TMD and SMD anthropometric measurements and TT, U-Ph, Snp-Nph and LE radiologic measurements were found to support MMS, which is one of the most widely used bedside intubation prediction tests. In addition to the inclusion of CBCT for intubation prediction, U-Ph and Snp-Nph radiologic measurements were added as difficult intubation markers.
