Backscattering Mueller matrix polarimetry estimates microscale anisotropy and orientation in complex brain tissue structure.

Purpose: Diffusion magnetic resonance imaging (dMRI) quantitatively estimates brain microstructure, diffusion tractography being one clinically utilized framework. To advance such dMRI approaches, direct quantitative comparisons between microscale anisotropy and orientation are imperative. Complete backscattering Mueller matrix polarized light imaging (PLI) enables the imaging of thin and thick tissue specimens to acquire numerous optical metrics not possible through conventional transmission PLI methods.

Multiphoton Microscopy Assessment of Healing From Tendon Laceration and Microthermal Coagula in a Rat Model.

Objectives: To study the healing response of rat Achilles tendon when lacerated or treated with intense therapeutic ultrasound (ITU) via utilization of multiphoton microscopy (MPM) imaging and histology.

Materials And Methods: The right Achilles tendon of each Sprague Dawley rat within a cohort was partially lacerated. 1 to 2 days post-surgery, each rat received ITU treatment of the Achilles tendon on either the right or left leg.

2024 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations: Summary From the Basic Life Support; Advanced Life Support; Pediatric Life Support; Neonatal Life Support; Education, Implementation, and Teams; and First Aid Task Forces.

This is the eighth annual summary of the International Liaison Committee on Resuscitation International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations; a more comprehensive review was done in 2020. This latest summary addresses the most recent published resuscitation evidence reviewed by the International Liaison Committee on Resuscitation task force science experts. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the quality of the evidence, using Grading of Recommendations Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations.

Principles of resuscitation for infants with severe bronchopulmonary dysplasia.

Severe bronchopulmonary dysplasia (sBPD) requiring invasive mechanical ventilation is a heterogeneous disease process that contributes to morbidity and mortality in infants. As the most common lung disease of prematurity, sBPD has a multitude of overlapping cardiac, airway, pulmonary vascular, and infectious phenotypic presentations that progress through four different phases of care. Premature infants with sBPD are at a high risk of acute decompensation and subsequent cardiopulmonary arrest.
