Indirect bypass for revascularization in Hutchinson-Gilford progeria syndrome: an illustrative case.

Purpose: Hutchinson-Gilford progeria syndrome (HGPS) is a rare genetic disorder characterized by premature aging. Cerebral hypoperfusion and stroke have been described in HGPS however revascularization techniques have not been reported from a neurosurgical perspective in HGPS patients.

Methods: We present a case of a pediatric patient with HGPS who underwent cerebral bypass along with a review of the literature.

Progression of experimental autoimmune encephalomyelitis in mice and neutrophil-mediated blood-brain barrier dysfunction requires non-muscle myosin light chain kinase.

Blood-brain barrier (BBB) dysfunction occurs in numerous central nervous system disorders. Unfortunately, a limited understanding of the mechanisms governing barrier function hinders the identification and assessment of BBB-targeted therapies. Previously, we found that non-muscle myosin light chain kinase (nmMLCK) negatively regulates the tight junction protein claudin-5 in brain microvascular endothelial cells (BMVECs) under inflammatory conditions.

Lung endothelial cell senescence impairs barrier function and promotes neutrophil adhesion and migration.

Cellular senescence contributes to inflammation and organ dysfunction during aging. While this process is generally characterized by irreversible cell cycle arrest, its morphological features and functional impacts vary in different cells from various organs. In this study, we examined the expression of multiple senescent markers in the lungs of young and aged humans and mice, as well as in mouse lung endothelial cells cultured with a senescence inducer, suberoylanilide hydroxamic acid (SAHA), or doxorubicin (DOXO).

Heterotopic Osteotomy for Intrathecal Baclofen Test Dose Administration in a Pediatric Patient With Spinal Fusion: A Technical Note.

Background And Importance: Intrathecal baclofen (ITB) pumps are used for the treatment of pediatric movement disorders that are rapidly progressive or do not respond to medical management. An ITB test dose is indicated in patients who have mixed tone, when the family remains unconvinced, or when insurance companies require it. Test doses are typically delivered by lumbar puncture; however, lumbar puncture in patients with heterotopic ossification of the lumbar vertebrae after a previous spinal fusion is not possible.

Evaluating the implementation of a hypertension program based on mHealth and community pharmacies integration to primary care centers at a municipality level in Argentina during the COVID-19 pandemic.

Introduction: While pharmacists-led interventions in hypertension have proven effective in high-income countries, their implementation and impact in low- and middle-income countries (LMIC) remain limited. This study assessed the implementation and outcomes of the hypertension program FarmaTeCuida (FTC), which integrated community pharmacies into the public primary care level using information and communication technologies. The study took place during the pandemic in General Pueyrredón, Buenos Aires, Argentina, so modifications to the implementation strategy and expected outcomes were also analyzed.
