Experimental Biomechanics of Neonatal Brachial Plexus Avulsion Injuries Using a Piglet Model.

Background: A brachial plexus avulsion occurs when the nerve root separates from the spinal cord during birthing trauma, such as shoulder dystocia or a difficult vaginal delivery. A complete paralysis of the affected levels occurs post-brachial plexus avulsion. Despite being reported in 10-20% of brachial plexus birthing injuries, it remains poorly diagnosed during the acute stages of injury, leading to poor intervention approaches.

Slowly quenched, high pressure glassy B2O3 at DFT accuracy.

Modeling inorganic glasses requires an accurate representation of interatomic interactions, large system sizes to allow for intermediate-range structural order, and slow quenching rates to eliminate kinetically trapped structural motifs. Neither first principles-based nor force field-based molecular dynamics (MD) simulations satisfy these three criteria unequivocally. Herein, we report the development of a machine learning potential (MLP) for a classic glass, B2O3, which meets these goals well.

Expert consensus and recommendations on the live attenuated hepatitis A vaccine and immunization practices in India.

While Hepatitis A Virus (HAV) vaccination in global immunization programs has shown a virtual elimination of the disease within few years of the vaccination program, changing epidemiological landscape in India underscores the need for evidence-based, updated guidance on immunization practices. In May 2024, a panel of 15 distinguished opinion leaders and an organizing committee convened for an intensive, face-to-face advisory board meeting on high burden of HAV infection among adults, increased mortality rate in adolescents, symptomatic presentation in children, and evolving landscape globally and within India. Extensive comparable deliberations on long-term follow-up data from India and data from country of origin advocated immunogenicity, tolerability, and long-term protective effects of single-dose live attenuated HAV vaccine in children.

Management of Cervical Spine Fractures and Injuries: A Literature Review.

Cervical spine injuries are one of the most common injuries of the spine that are encountered in the emergency department (ED). More than half of all spinal injuries presenting to the ED involve the cervical spine, with nearly half of them resulting from road traffic accidents. The majority of spinal cord injuries are found to occur in males of younger age groups, with almost half of them resulting in incomplete spinal cord injuries.
