From August 91 to December 94, 20 external fixators were used for severely injured patients (avg. ISS 25.2). The fractures were essentially open book with or without lateral compression and vertical lesions. The indication for fixation was treatment of shock and stabilization in 8 cases, stabilization alone in 9 cases, and in 3 cases as complementary fixation after internal fixation of posterior lesions. The fixation of the pelvis was effective on the amount of blood loss. One acetabulum fracture required surgery, two patients had internal fixation for loss of reduction and two others for late pubic and posterior pain. The clinical results are good; they are more related to the severity of the initial lesion than to the mode of fixation or the quality of the reduction. No superficial sepsis or osteitis was observed in relation to the pins.

Background: Traumatic anterior shoulder dislocation is the most common type of joint dislocation, with an incidence of 11 to 29 per 100 000 persons per year. Controversy still surrounds the recommendations for treatment and the available procedures for surgical stabilization.
Methods: This review is based on pertinent publications (2014-2024) that were retrieved by a selective search in the PubMed and Google Scholar databases.
Impact of human intervention and predator-prey dynamics on ecosystem virus transmission.

Humans and predators occupy dominant positions in ecosystems and are generally believed to play a decisive role in maintaining ecosystem stability, particularly in the context of virus transmission. However, this may not always be the case. By establishing some ecosystem virus transmission models that cover both human perspectives and predators, we have drawn the following conclusions: (1) Controlling vaccination activities from the human perspective can potentially lower the transmission rate and improve herd immunity, thereby indirectly protecting unvaccinated risk groups.

Patent ductus arteriosus (PDA) stenting is a vital intervention for neonates with ductal-dependent blood flow, offering an attractive alternative to surgical shunt placement. Despite its benefits, the procedure poses risks such as ductal spasm, branch pulmonary artery compromise, and pseudoaneurysm formation. This report presents two complex neonatal cases with distinct outcomes.

Serum albumin has myriad uses in biotechnology, but its value as a nanocarrier or nanoplatform for therapeutics is becoming increasingly important, notably with albumin-bound chemotherapeutics. Another emerging field is the fabrication of biopolymeric nanoparticles using albumin as a building block to achieve highly-tunable nonimmunogenic capsules or scaffolds that may be cheaply and reliably produced. The aim of this study was to characterize and optimize the desolvation process used for fabrication of albumin nanoparticles under ambient conditions, studying both glutaraldehyde (GT) and glucose (GLU) as crosslinking agents and the effect of various synthesis conditions including pH, electrolyte concentration, and rate of desolvation on particle size and stability.

Background: Applying nowcasting methods to partially accrued reportable disease data can help policymakers interpret recent epidemic trends despite data lags and quickly identify and remediate health inequities. During the 2022 mpox outbreak in New York City, we applied Nowcasting by Bayesian Smoothing (NobBS) to estimate recent cases, citywide and stratified by race or ethnicity (Black or African American, Hispanic or Latino, and White). However, in real time, it was unclear if the estimates were accurate.
