Article Synopsis
  • A pilot study compared mixed reality-assisted spinal puncture (MRasp) to landmark-guided spinal puncture (LGsp) among novice practitioners performing spinal anaesthesia on elderly patients (age ≥65).
  • Results showed that the MRasp group had significantly fewer needle insertion attempts (1.0 vs 2.0) and a higher rate of successful first-attempt needle insertion (72.2% vs 44.4%).
  • Although MRasp improved efficiency, the overall incidence of perioperative complications was similar in both groups, indicating the need for further randomized controlled trials to confirm these findings.

Nasal administration can bypass the blood-brain barrier and directly deliver drugs to the brain, providing a non-invasive route for central nervous system (CNS) diseases. Inspired by the appearance that a gate can block the outside world and the characteristics of the sol-gel transition can form a "gate" in the nasal cavity, a Drop to Gate nasal drop (DGND) is designed to set a gate in nose, which achieves protecting role from the influence of nasal environment. The DGND demonstrates the efficiency and application prospect of delivering drugs to the brain through the N-to-B.

  • The study compared the effectiveness of High-flow nasal oxygen (HFNO) versus regular nasal tubing (CNC) in preventing hypoxemia in elderly patients (aged 65+) undergoing gastroscopy with sedation.
  • Results showed that hypoxemia occurred significantly less in the HFNO group (3.2%) compared to the CNC group (22.6%) and they experienced shorter durations of low oxygen levels.
  • HFNO also resulted in higher minimum oxygen saturation levels and quicker recovery times, suggesting it is a safe and effective standard for oxygen delivery in this patient group.

  • The study aims to identify service members with concurrent traumatic brain injury (TBI) and ocular trauma (OT) to improve early detection and treatment, focusing on injuries sustained in non-combat situations.
  • Data from military health records between 2017 and 2021 revealed 4.7% of OT patients also had TBI, with specific injury mechanisms like blasts and falls showing significant association with this concurrence.
  • The findings suggest a need for heightened screening for TBI in OT patients, especially those with serious injuries like orbital fractures, as they are at a higher risk for concomitant TBI.

Leukoaraiosis (LA) is strongly associated with impaired cognition and increased dementia risk. Determining effective and robust methods of identifying LA patients with mild cognitive impairment (LA-MCI) is important for clinical intervention and disease monitoring. In this study, an ensemble learning method that combines multiple magnetic resonance imaging (MRI) morphological features is proposed to distinguish LA-MCI patients from LA patients lacking cognitive impairment (LA-nCI).

TRPA1 is pivotal in cold hypersensitivity, but its regulatory mechanisms in inflammatory cold hyperalgesia remain poorly understood. We show here that the upregulation of SUMO1-conjugated protein levels in a complete Freund's adjuvant (CFA)-induced inflammatory pain model enhances TRPA1 mRNA stability, ultimately leading to increased expression levels. We further demonstrate that hnRNPA1 binds to TRPA1 mRNA, and its SUMOylation, upregulated in CFA-induced inflammatory pain, contributes to stabilizing TRPA1 mRNA by accumulating hnRNPA1 in the cytoplasm.

Abstract: IntroductionWe aimed to identify injury-related risk factors for secondary cataract incidence after eye and brain injury and polytrauma. We also examined the effect of direct and indirect eye injury management on cataract diagnosis and treatment. Prevention or mitigation strategies require knowledge of the causes and types of combat injuries, which will enable more appropriate targeting of resources toward prevention and more efficient management of such injuries.

can cause severe foodborne illness, including miscarriage during pregnancy or death in newborn infants. When outbreaks of illness occur, it may be possible to determine the food source of the outbreak. However, most reported illnesses do not occur as part of a recognized outbreak and most of the time the food source of sporadic illness in people cannot be determined.
