Objectives: To analyse the data on skydiving deaths and injuries collected prospectively by the French Parachuting Federation (FFP) between 2010 and 2019.
Design: Prospective cohort study.
Methods: Data on number of skydiving deaths and injuries were collected prospectively between January 2010 and December 2019, among all skydivers licensed to the FFP, via a standardised report form that included the skydiver's sex and level of experience (classified as tandem, student, or experienced), deaths, injuries, and injury location. The number of licensees, jumps, skydiving deaths and injuries were analysed descriptively and expressed as rates per 100,000 jumps and per 1000 skydivers with 95% confidence intervals (95%CI).
Results: Among the almost 6.2 million jumps performed by 519,620 skydivers over 10 years between 2010 and 2019, 35 deaths and 3015 injuries were reported, corresponding to 0.57 deaths (95%CI 0.38 to 0.75) and 49 injuries (95%CI 47.0 to 50.1) per 100,000 jumps. Male skydivers had a five times higher deaths rate than women (RR=4.8, 95%CI 1.5 to 15.6). There was no death in tandem skydivers. Student skydivers had a six times higher risk of injuries than experienced skydivers (RR=6.1, 95%CI 5.7 to 6.6) and tandem skydivers had a significant lower risk of injuries than experienced skydivers (RR=0.07, 95%CI 0.06 to 0.08). 83.3% of the injuries occurred during the landing phase and 64.3% concerned the lower limb.
Conclusions: This large survey shows that the highest risk of death concerned experienced and male skydivers, and the highest risk of injuries concerned student skydivers. It also shows the safety of tandem skydiving. These results can be of help to develop skydiving-related deaths and injuries risk reduction strategies, and thus improve the global skydiving safety and the skydivers' health.

Background: There is higher prevalence of chronic kidney disease (CKD) in burn patients after hospital discharge; however, the cause remains unclear. This study aimed to investigate the lasting impacts of severe burns on the kidneys and to explore potential treatments.
Methods: The study examined the effects of burning on healthy mice and adenine-induced CKD mice.

Introduction Trauma is the leading cause of death for individuals under 45 in the United States (US), with significant disparities in outcomes among minority groups. Latinos, the largest ethnic minority in the US, often face barriers to optimal trauma care that may require additional resources. This study aimed to compare trauma outcomes for Latino patients treated at Level I versus Level II/III trauma centers (TCs).

Bioelectrical stimulation is a powerful technique used to promote tissue regeneration, but it can be hindered by an "electrical overload" phenomenon in the core region of stimulation. We develop a threaded microneedle electrode system that protects against "electrical overload" by delivering medicinal hydrogel microspheres into the core regions. The threaded needle body is coated with polydopamine and chitosan to enhance the adhesion of microspheres, which are loaded into the threaded grooves, allowing for their stereoscopic release in the core regions.

Objectives: The objective of this study is to evaluate the incidence and volume of contrast medium extrusion when activated with a laser and to compare these outcomes with those of other irrigation techniques.
Materials And Methods: Sixteen cadaver mandibles containing 116 single-rooted teeth were prepared using conventional rotary instrumentation. The teeth were randomly assigned to four irrigation groups: side-vented needle, sonic irrigation, laser activation at the orifice, and laser activation at the middle third of the canal.

Acute brain injuries (ABIs) encompass a broad spectrum of primary injuries such as ischemia, hypoxia, trauma, and hemorrhage that converge into secondary injury where some mechanisms show common determinants. In this regard, astroglial connexin and pannexin channels have been shown to play an important role. These channels are transmembrane proteins sharing similar topology and form gateways between adjacent cells named gap junctions (GJs) and pores into unopposed membranes named hemichannels (HCs).
