Blunt force trauma (BFT), the injury of the body by forceful impacts such as falls, motor vehicle crashes and collisions, causes damage to bio-organs that can lead to life-threatening situations. To address the unmet need of bioprotection materials for BFT, we developed a novel, liquid nanofoam (LN)-based system. The LN system employs a unique mechanism of energy absorption, i.e. the external force-aided, nanoscale liquid flow. Under mechanical loading, the LN system effectively protected human cells from force-induced deformation and cell death. In addition to effective mitigation of the upregulation of stress and inflammatory genes, LN prevented blunt-force-induced damage of multiple vital organs including liver, kidney, heart, and lungs. To our knowledge, this is the first material of its kind that is biocompatible and capable of effectively protecting biotissues from BFT on molecular, cellular and tissue levels.

Precipitate labor and neonaticide can present with overlapping features, often posing significant challenges in forensic interpretation. Differentiating between these possibilities is essential for reaching accurate medicolegal conclusions. This case report examines the forensic complexities involved in distinguishing precipitate labor from neonaticide.

Mechanotransduction is vital for sensing various mechanical stimuli, including blunt force and dynamic light touch. The sensation of a punctate mechanical force is very different from that of a brush swept across the skin, yet both involve mechanical stimulation of the skin and embedded sensory afferent endings. However, the sensory neuron mechanisms contributing to punctate vs light touch somatosensation, and how they might become dysregulated in nerve injury to cause pain, remain unclear.

Background: There is growing evidence throughout medicine, including otolaryngology, that reimbursements have consistently been falling over the last 2 decades, which no obvious end in sight. Herein, we aim to educate otolaryngologists on the macro and microeconomic forces acting on health economics, detail the trends in reimbursements, and discuss how these trends affect providers and patients.
Methods: A narrative review of changes in reimbursements and practice patterns within otolaryngology was performed.

Pain can impair exercise performance, but its influence on motor control, in particular the effect of robust experimental pain on the timecourse of corticomotor responses throughout prolonged, exhaustive cycling, remains unclear. We tested the hypothesis that an augmented experimental pain intervention applied to exercising and non-exercising limbs would modulate neuromuscular function, corticospinal excitability and inhibition, and exacerbate perceptual and cardiorespiratory responses to exercise. Ten healthy adults (two females) completed three single-leg cycling sessions at 60% peak power output to failure: without experimental pain (CTRL), with intermittent occlusions applied to the resting leg (CONTRA), and with occlusions upon the exercising leg (IPSI).

Background: Seymour fractures are a unique type of pediatric distal phalangeal fracture that can be easily misdiagnosed as a simple nail-bed injury or mallet finger. Because of this potential for misdiagnosis, clear communication with consulting physicians regarding physical examination findings, such as nail plate avulsion and radiographic findings, is necessary. Seymour fractures involve the open physis and the germinal matrix, which become interposed in the fracture site, increasing the likelihood of infection.
