Background: Delayed cerebral ischemia (DCI) is one of the most feared complications in aneurysmal subarachnoid hemorrhage (SAH). Animal models are crucial to studying the disease mechanisms and potential treatments. DCI in rodents was thought to not exist; herein we examine literature and our experience with DCI in rodents.

The mammalian cortex is composed of a highly diverse set of cell types and develops through a series of temporally regulated events that build out the cell type and circuit foundation for cortical function. The mechanisms underlying the development of different cell types remain elusive. Single-cell transcriptomics provides the capacity to systematically study cell types across the entire temporal range of cortical development.

This study reports on the development and testing of a comprehensive diabetes telemonitoring program tailored to meet the needs of underserved Hispanic/Latino patients with diabetes. Individuals participating in the culturally tailored program had significantly better 6-month outcomes than those receiving comprehensive outpatient management for A1C, blood pressure, and diabetes self-efficacy, with no differences between groups in quality of life, medication adherence, emotional functioning, patient activation, or unscheduled physician visits. These findings suggest that culturally congruent diabetes telemonitoring may be effective for this underserved population.

Quantifying competition load with kinematic variables from inertial devices provides critical insights into player performance, a practice well adopted especially in team sports. This study aimed to analyse load variables in elite padel players, distinguishing between match winners and losers. Data were collected from 83 players across 23 professional circuit matches.

Article Synopsis
  • Biological aging involves a gradual loss of homeostasis in molecular and cellular functions, particularly in the brain, which contains diverse cell types that differ in their aging resilience.
  • This study offers an extensive single-cell RNA sequencing dataset of approximately 1.2 million transcriptomes from brain cells in young and aged mice, identifying 847 cell clusters and 14 age-biased clusters predominantly involving glial types.
  • Key findings reveal specific gene expression changes with aging, including decreased neuronal function genes and increased immune-related genes, particularly in cells around the third ventricle of the hypothalamus, suggesting its critical role in the aging process of the mouse brain.
