Purpose: To analyze the etiology, diagnosis, and incidence of head and neck (HN) injuries among ocean surfers.
Methods: The National Electronic Injury Surveillance System database was queried for surfing HN injuries presenting to United States emergency departments (EDs) between January 2003 and December 2022. Date of presentation, age, sex, race, injured body part, injury diagnosis, and disposition, as well as a brief injury narrative, were included in the data. National estimates (NEs) were calculated using the associated statistical weight of the reporting hospital.
Results: A total of 1,359 surfing-related HN injuries (NE, 90,872) were included in this study. The average age at presentation was 29.2 ± 13.8 years (range, 3 to 81 years). The most commonly specified mechanisms of injury were impact with board (NE, 48,360 [53%]) and impact with ocean floor (NE, 8,690 [10%]). Concussions represented 5% of surfing HN injuries and occurred at a higher rate (8%) in the age group younger than 20 years. There were statistically significant decreases in overall HN injuries ( < .01) (coefficient, -270; 95% confidence interval [CI], -355 to -206), lacerations ( < .01) (coefficient, -208; 95% CI, -258 to -158), and impact-with-board injuries ( < .01) (coefficient, -177; 95% CI, -327 to -117) presenting to United States EDs from 2003 to 2022.
Conclusions: Although surfing HN injury ED presentations decreased from 2003 to 2022, the rate of surfing-related concussions presenting to EDs remained steady. Concussions therefore remain a significant concern in surfing, especially among surfers under 20 years of age.
Clinical Relevance: As the sport of surfing has increased in popularity, it is important to understand the range of surfing injuries seen in EDs. HN injuries, especially concussions, should be thoroughly investigated to better understand the risks of ocean surfing, to advise athletes, and to develop effective injury prevention strategies.

We demonstrate that applied electric fields at interfaces can control the oxidative addition/reductive elimination equilibria of surface-attached molecular catalysts without any synthetic modification. Density functional theory (DFT) calculations show that the oxidative addition of HCl to a Co complex is "field switchable", being favorable under negative fields but unfavorable under sufficiently positive fields. Extending the analysis to different substrates (O, H) and metal centers (Rh, Ir) reveals consistent trends in the magnitude of the electric field effect: Co > Rh ≈ Ir and HCl > O > H.

Objective: This systematic review aimed to evaluate the current evidence regarding the impact of postbiotics on dental caries, focusing on the effectiveness of postbiotic interventions in caries prevention, mechanisms of action, optimal dosages, and administration protocols.
Methods: A literature search was conducted across PubMed/MEDLINE, Scopus, Web of Science, and the Cochrane Library. Eligible studies included randomized controlled trials, quasi-experimental, observational, and in vitro studies.

Background: Osteosarcoma, an aggressive bone malignancy predominantly affecting children and adolescents, presents significant therapeutic challenges with a 5-year survival rate below 30% in metastatic cases. T-cell exhaustion, characterized by the overexpression of immune checkpoint molecules, contributes to osteosarcoma progression and immune evasion. Although targeting these inhibitory pathways has shown potential in restoring T-cell activity, the molecular regulators of T-cell depletion in osteosarcoma are poorly understood.

After longer duration space missions, some astronauts experience structural and functional changes in the eye and structural changes in the brain, termed Spaceflight-Associated Neuro-Ocular Syndrome (SANS). Countermeasures against SANS are required to minimize potential operation impacts and negative long-term health consequences. Headward fluid shifts, which appear to promote SANS, provide a target for countermeasures.
