Deep learning for sex determination: Analyzing over 200,000 panoramic radiographs

The objective of this study is to assess the performance of an innovative AI-powered tool for sex determination using panoramic radiographs (PR) and to explore factors affecting the performance of the convolutional neural network (CNN). The study involved 207,946 panoramic dental X-rays and their corresponding reports from 15 clinical centers in São Paulo, Brazil. The PRs were acquired with four different devices, and 58% of the patients were female. Data preprocessing included anonymizing the exams, extracting pertinent information from the reports, such as sex, age, type of dentition, and number of missing teeth, and organizing the data into a PostgreSQL database. Two neural network architectures, a standard CNN and a ResNet, were utilized for sex classification, with both undergoing hyperparameter tuning and cross-validation to ensure optimal performance. The CNN model achieved 95.02% accuracy in sex estimation, with image resolution being a significant influencing factor. The ResNet model attained over 86% accuracy in subjects older than 6 years and over 96% in those over 16 years. The algorithm performed better on female images, and the area under the curve (AUC) exceeded 96% for most age groups, except the youngest. Accuracy values were also assessed for different dentition types (deciduous, mixed, and permanent) and missing teeth. This study demonstrates the effectiveness of an AI-driven tool for sex determination using PR and emphasizes the role of image resolution, age, and sex in determining the algorithm's performance.     

Characterising the psychiatric comorbidities among adults with ADHD who have a history of offending

The prevalence of attention deficit hyperactivity disorder (ADHD) among adult offenders is significantly higher than in the general population. Adults with ADHD often present with multiple psychiatric comorbidities. This study aims to characterise the comorbidities presented by adults with ADHD who have offended and also to investigate predictors of offending among this population. Seventy-three participants with a diagnosis of adult ADHD were divided into a group with a history of offending behaviour (n = 30) and a group of non-offenders (n = 43). Groups were compared on measures of ADHD symptoms, substance use and DSM-IV Axis I and Axis II disorders using the Millon Clinical Multiaxial Inventory – 3rd Edition. Major depression, cannabis use and childhood hyperactivity-impulsivity symptoms predicted offending. These findings indicate that adults with ADHD who have a history of offending behaviour are more likely to present with complex psychiatric needs.     

Offenders as victims: post-traumatic stress disorder and substance use disorder among male prisoners

Background: Comorbid substance use disorder(s) and post-traumatic stress disorder (SUD-PTSD) is common among prisoners and linked to an increased risk of criminal recidivism; however, little is known about the characteristics of prisoners with this comorbidity. Aim: This study provides a preliminary examination of the clinical and criminal profile of male inmates with symptoms of SUD-PTSD, and examines whether this profile differs according to whether a person has experienced a trauma while in prison. Methods: Thirty male inmates from two correctional centres in Sydney, Australia, were recruited and assessed using a structured interview. Results: The sample reported extensive criminal, substance use and trauma histories. A history of substance dependence was almost universal (90%) and 56.7% met diagnostic criteria for PTSD with the remainder experiencing sub-threshold symptoms. Forty-three per cent reported a traumatic event while in prison. Those who had experienced trauma in prison, compared to those who had not, were more likely to nominate heroin as their main drug of concern and to be receiving drug treatment in prison. There was also a trend toward inmates who had experienced a trauma in prison being more likely than inmates who had no prison trauma to have experienced a physical assault. Conclusion: Male prisoners with SUD-PTSD are a high-needs group yet treatment responses are poor. Further research examining treatment options for this comorbidity may improve prisoner well-being and reduce recidivism.     

CONTINUITY / DISCONTINUITY

Starting from issues Wang Hui raises in “The Dialectics of Autonomy and Opening” (Critical Asian Studies 43:2), the authors of this article focus on the problematic coexistence of continuities and discontinuities in modern and contemporary Chinese politics. China's present role in the international scene, they argue, cannot be assessed in terms of economic performance, but requires new perspectives for rethinking the search of China for an original path in domestic politics, as well as the universalistic attitude toward the various forms of thinking coming from all over the world.
