Time Is a Tool: Evaluation of a Prolonged Casualty Care Curriculum With a Focus on Temporal Fidelity.
Mil Med
January 2025
Department of Military and Emergency Medicine, Uniformed Services University, Bethesda, MD 20814, USA.
Introduction: In current and anticipated future conflicts, including large-scale combat operations, medical teams are tasked to provide prolonged casualty care (PCC) or extended patient care that occurs when delays in evacuation exceed the team's capabilities. Although the principles of PCC are often taught to military medical providers using simulation, educators rarely dedicate the time to training required to simulate the prolonged nature of these encounters. Therefore, a lack of knowledge exists regarding which aspects of extended care may be lost in an accelerated training scenario.

The duration of mechanical systole-also termed the flow time (FT) or left ventricular ejection time (LVET)-is measured by Doppler ultrasound and increasingly used as a stroke volume (SV) surrogate to guide patient care. Nevertheless, confusion exists as to the determinants of FT and a critical evaluation of this measure is needed. Using Doppler ultrasound of the left ventricular outflow tract velocity time integral (LVOT VTI) as well as strain and strain rate echocardiography as grounding principles, this brief commentary offers a model for the independent influences of FT.

Department of Pediatrics, UPMC Children's Hospital of Pittsburgh, Pittsburgh, PA.
Objectives: To report the feasibility of a fluid management practice bundle and describe the pre- vs. post-implementation prevalence and odds of cumulative fluid balance greater than 10% in critically ill pediatric patients with respiratory failure.
Design: Retrospective cohort from May 2022 to December 2022.
Tailoring Exercise Prescription for Effective Diabetes Glucose Management.
J Clin Endocrinol Metab
January 2025
Department of Kinesiology and Health, Rutgers University, New Brunswick, NJ 08901, USA.
Context: Physical activity, exercise, or both are a staple of lifestyle management approaches both for type 1 diabetes mellitus (T1DM) and type 2 diabetes (T2DM). While the current literature supports both physical activity and exercise for improving glycemic control, reducing cardiovascular risk, maintaining proper weight, and enhancing overall well-being, the optimal prescription regimen remains debated.
Evidence Acquisition: We searched PubMed and Google Scholar databases for relevant studies on exercise, insulin sensitivity, and glycemic control in people with T1DM and T2DM.
Nociceptor sodium channels shape subthreshold phase, upstroke, and shoulder of action potentials.
J Gen Physiol
March 2025
Institute for Neurophysiology, Uniklinik RWTH Aachen University, Aachen, Germany.
Voltage-gated sodium channels (VGSCs) in the peripheral nervous system shape action potentials (APs) and thereby support the detection of sensory stimuli. Most of the nine mammalian VGSC subtypes are expressed in nociceptors, but predominantly, three are linked to several human pain syndromes: while Nav1.7 is suggested to be a (sub-)threshold channel, Nav1.
