Article Synopsis
  • Animal studies indicate that the effectiveness of double sequential external defibrillation (DSED) may depend on the timing between the two shocks, known as the "DSED interval," but this has not been tested in humans.
  • A retrospective study of adult patients with refractory ventricular fibrillation (VF) explored how different DSED intervals affect outcomes like VF termination, return of spontaneous circulation (ROSC), and survival, revealing that shorter intervals (<75 ms) were linked to better outcomes.
  • The study found that while shorter DSED intervals improved chances of VF termination and ROSC, there was no significant link between DSED intervals and survival to discharge or neurological status.

Glucagon-like peptide-1 receptor signaling modifies the extent of diabetic kidney disease through dampening the receptor for advanced glycation end products-induced inflammation.

Kidney Int

January 2024

Department of Diabetes, Monash University, Central Clinical School, Alfred Research Alliance, Melbourne, Victoria, Australia; Diabetes Complications Division, Baker Heart & Diabetes Institute, Melbourne, Victoria, Australia; Drug Discovery Biology, Monash Institute of Pharmaceutical Sciences, Monash University Parkville Campus, Parkville, Victoria, Australia. Electronic address:

Glucagon like peptide-1 (GLP-1) is a hormone produced and released by cells of the gastrointestinal tract following meal ingestion. GLP-1 receptor agonists (GLP-1RA) exhibit kidney-protective actions through poorly understood mechanisms. Here we interrogated whether the receptor for advanced glycation end products (RAGE) plays a role in mediating the actions of GLP-1 on inflammation and diabetic kidney disease.

India has one of the most unequal healthcare systems globally, lagging behind its economic development. Improved primary care and primary health care play an integral role in overcoming health disparities. Family medicine is a subset of primary care-delivered by family physicians, characterized by comprehensive, continuous, coordinated, collaborative, personal, family and community-oriented services-and may be able to fill these gaps.

Association of Dual-Task Gait Cost and White Matter Hyperintensity Burden Poststroke: Results From the ONDRI.

Neurorehabil Neural Repair

July 2023

Department of Medicine (Geriatrics) and Epidemiology and Biostatistics, Schulich School of Medicine and Dentistry, Western University, London, ON, Canada.

Background: Acute change in gait speed while performing a mental task [dual-task gait cost (DTC)], and hyperintensity magnetic resonance imaging signals in white matter are both important disability predictors in older individuals with history of stroke (poststroke). It is still unclear, however, whether DTC is associated with overall hyperintensity volume from specific major brain regions in poststroke.

Methods: This is a cohort study with a total of 123 older (69 ± 7 years of age) participants with history of stroke were included from the Ontario Neurodegenerative Disease Research Initiative.

Article Synopsis
  • Immune checkpoint inhibitors (ICPI) are a cancer treatment that can be used for various tumor types, but their trials have mostly focused on specific cancer sites. This study reviews trial data to evaluate the effectiveness of these treatments based on PD-L1 expression as a potential biomarker for broader cancer applications.
  • A systematic literature review was conducted on multiple databases, targeting studies involving adults with solid cancers (excluding melanomas) treated with ICPIs, emphasizing phase III randomized control trials for measuring outcomes like overall survival and adverse effects.
  • The meta-analysis included 46,510 participants and found that ICPIs significantly improved overall survival, particularly in lung cancers, head and neck cancers, and gastroesophageal junction cancers, with overall survival rates differing in

Purpose: Spine stereotactic body radiation therapy (SBRT) results in improved local control and pain response compared with conventional external beam radiation therapy. Consensus exists stipulating that magnetic resonance imaging-based delineation of the clinical target volume (CTV) is critical and based on spine segment sector involvement. The applicability of contouring guidelines to metastases involving the posterior elements alone remains to be validated, and the purpose of this report was to determine the patterns of failure and safety of treating posterior element metastases when the vertebral body (VB) was intentionally excluded from the CTV.

Objective: Neonatal imaging studies report corpus callosum abnormalities after neonatal hypoxic-ischaemic encephalopathy (HIE), but corpus callosum development and relation to cognition in childhood are unknown. Using magnetic resonance imaging (MRI), we examined the relationship between corpus callosum size, microstructure and cognitive and motor outcomes at early school-age children cooled for HIE (cases) without cerebral palsy compared to healthy, matched controls. A secondary aim was to examine the impact of HIE-related neonatal brain injury on corpus callosum size, microstructure and growth.
