Article Abstract
Background: Although understanding long-term trends in adolescent screen time and the influence of family structure is essential, there is a lack of research addressing these issues comprehensively.
Objective: This study aimed to conduct comprehensive investigations into adolescent screen time before and during the COVID-19 pandemic, with a particular focus on family structures.
Methods: This study used nationwide, large-scale data from the Korea Youth Risk Behavior Web-Based Survey from South Korea. We aimed to indicate the changes in adolescent screen time over 15 years from 2008 to 2022. Weighted linear regression was used to analyze annual trends in screen time before and during the pandemic, and stratified analyses were conducted to examine associated risk factors across different family structures.
Results: This study used data from a total of 836,972 individuals (n=403,456, 48.2% women), with an age range of 12-18 years. The analysis revealed an overall increase in screen time prepandemic (β=8.06, 95% CI 7.74-8.39), with a notable increase observed at the onset of the pandemic (β=162.06, 95% CI 159.49-164.64). Among diverse family structures, the orphanage group showed the most substantial increase in screen time during the pandemic (β=221.90, 95% CI 159.62-284.17). Risk factors associated with screen time during the pandemic varied by family structure. Notably, the nuclear family group presented distinct screen time-related risk factors, including grade, region of residence, physical activity frequency, sadness and despair, and the highest education level of parents.
Conclusions: There has been a notable increase in average screen time among adolescents since the onset of the pandemic, with the orphanage group exhibiting a pronounced trend. The risk factors associated with screen time during the pandemic varied for each family structure. Findings from this study suggest that the implementation of individualized measures tailored to each family structure should be adopted to effectively address the increased issue of adolescent screen time since the pandemic.

Behind arthritis and heart disease, hearing loss (HL) is the third most prevalent chronic condition in older Americans, with primary care providers playing a crucial role in its identification. Understanding the practices and perceptions of primary care providers in hearing health is key to understanding gaps in hearing health care for patients. We conducted a quality improvement study at an urban tertiary academic facility from January–June 2024.

Introduction: Trousseau syndrome (TS) represents a significant vascular thromboembolic event in cancer patients and has progressively gained attention as a critical clinical concern in recent years. The aim of this study is to investigate the survival status and prognostic factors in patients with TS whose initial clinical manifestation was acute ischemic stroke (AIS).
Methods: A retrospective analysis was conducted on 24 TS patients hospitalized at the Affiliated Hospital of Jiangsu University between 2018 and 2024.

Introduction: The transition from traditional laparoscopy to robotic surgery marks a significant chage in surgical practice. An understated aspect of this transition may be the three dimensional (3D) view from the surgical console. This study hypothesises that acclimatisation with 3D virtual reality (VR) video may enhance robotic simulator performance in novice robotic surgeons.

Clinical Relevance: Dry eye disease (DED) is associated with use of video screen based gadgets and long hours spent looking through microscopes. Use of 3D goggles to view 3D screens leads to eye strain and worsening of dry eye symptoms. It is important to identify and treat the symptoms in professions carrying a high risk of DED.

Background: Changes in socioeconomic inequalities in health behaviours following the COVID-19 pandemic remain unknown, particularly among Japanese school-aged adolescents. Therefore, in this study, we examined changes in socioeconomic inequalities in school-aged adolescents' health behaviours, including physical activity (PA), screen time (ST), sleep duration, breakfast consumption, and bowel movement frequency, before and after the pandemic.
Methods: This three-wave repeated cross-sectional study utilised data from the 2019, 2021, and 2023 National Sports-Life Survey of Children and Young People in Japan, analysing data from 766, 725, and 604 participants aged 12-18 years, respectively.
