Headgear designed to protect girls' lacrosse athletes is widely available and permitted for voluntary use; however, it remains unknown how policies mandating headgear use may change the sport and, particularly regarding impacts during game-play. Therefore, this study compares the impact rates and game play characteristics of girls' high school lacrosse in Florida which mandates headgear use (HM), with states having no headgear mandate (NHM). ⋯ These findings demonstrate that mandating headgear use was associated with a two-fold greater likelihood of sustaining a head impact during game play compared to NHM states. A majority of head impacts in both HM and NHM states were caused by illegal stick contact that did not result in penalty.

The purpose of this study was to investigate the relationship between Helicobacter pylori (H. pylori) infection-induced changes in gastric mucosal immune cells and glandular epithelial cell damage and the histopathological characteristics of these changes. ⋯ For controlling the occurrence and development of gastric cancer and effective immune intervention, it is essential to grasp the relationship between H. pylori infection-induced changes in gastric mucosal immune cells and glandular epithelial cell damage and its histopathological characteristics.

The association between internet addiction and sleep quality among medical students in Saudi Arabia.
Sleep is one of the fundamental human needs, essential for maintaining a high quality of life and mental and physical well-being across all age groups. Poor sleep quality often stems from negative lifestyle habits, including excessive internet usage. Therefore, it is important to determine the prevalence of internet gaming disorder among youth in Saudi Arabia and to examine the relationship between internet addiction levels and sleep quality. ⋯ These findings, while exploratory, offer valuable insights into potential interventions, strategies, and programs for mitigating internet addiction and enhancing sleep quality among medical college students.

Enamel matrix derivative in the treatment of tooth replantation: from a biological basis to clinical application.
An efficient therapeutic strategy for patients with replanted teeth has been extremely challenging because complete displacement of the teeth is inevitably accompanied by severe damage to periodontal tissue. Enamel matrix derivative (EMD) shows promise for periodontal regeneration, but its effects on replanted teeth remain unknown. This study systematically summarized the biological basis of EMD in replantation dental therapy and assessed its effect on clinical prognosis. ⋯ For patients with replanted teeth, EMD treatment may not result in a numerical increase in normal PDL healing. However, as a biological regulator, EMD may arrest the progression of resorption, thus reducing the risk of extraction in the early stage. Well-designed randomized trials are required to validate these results due to the poor quality of evidence.

In this study in a tertiary care hospital, we examined the characteristics of the different microbial etiologies of infective endocarditis (IE) and the factors associated with embolic events. ⋯ Our study suggests that enterococcal IE is often associated with a previous healthcare procedure or hospital admission and heart failure. Staphylococcus aureus etiology and IE of the multiple valves are associated with a higher rate of all embolic events but not cerebral embolisms. Echocardiography-disclosed vegetation is associated with a higher occurrence of embolisms.
