AI Article Synopsis

  • This study looks at the link between traumatic brain injury (TBI) and the risk of stroke in young-to-middle-aged adults aged 18 to 49, highlighting that TBI significantly increases the likelihood of having a stroke.
  • Data from over 500,000 adults with TBI revealed that stroke incidence was 3.82 per 1000 person-years compared to 1.61 in healthy controls, with TBI patients facing nearly double the risk of stroke.
  • The findings stress the importance of stroke prevention measures in younger patients after TBI, emphasizing the need for regular health checkups and lifestyle changes to manage stroke risk factors.

Article Abstract

Background: Although stroke is commonly perceived as occurring in older adults, traumatic brain injury, one of the risk factors for stroke, is a leading cause of death in the younger adults. This study evaluated stroke risk in young-to-middle-aged adults based on traumatic brain injury severity and stroke subtypes.

Methods And Results: For this retrospective, population-based, cohort study, data of adults aged 18 to 49 years who were diagnosed with traumatic brain injury were obtained from the Korean National Health Insurance Service between 2010 and 2017. Traumatic brain injury history was measured based on the , , codes. Posttraumatic brain injury stroke risk was analyzed using a time-dependent Cox regression model. At baseline, 518423 patients with traumatic brain injury and 518 423 age- and sex-matched controls were included. The stroke incidence rate per 1000 person-years was 3.82 in patients with traumatic brain injury and 1.61 in controls. Stroke risk was approximately 1.89 times as high in patients with traumatic brain injury (hazard ratio, 1.89 [95% CI, 1.84-1.95]). After excluding stroke cases that occurred within 12 months following traumatic brain injury, these significant associations remained. In the subgroup analysis, patients with brain injury other than concussion had an approximately 9.34-fold risk of intracerebral hemorrhage than did the controls.

Conclusions: Stroke prevention should be a priority even in young-to-middle-aged adult patients with traumatic brain injury. Managing stroke risk factors through regular health checkups and modifying health-related behaviors is necessary to prevent stroke.

This work studies upper-limb impairment resulting from stroke or traumatic brain injury and presents a simple technological solution for a subset of patients: a soft, active stretching aid for at-home use. To better understand the issues associated with existing associated rehabilitation devices, customer discovery conversations were conducted with 153 people in the healthcare ecosystem (60 patients, 30 caregivers, and 63 medical providers). These patients fell into two populations: spastic (stiff, clenched hands) and flaccid (limp hands).

Innovations in pharmaceutical science drive new treatment approaches for cancer and brain injury. This Patent Highlight reviews findings from three patents focused on kinase inhibition in cancer therapy and using biomarkers to assess brain injury. By targeting key enzymes such as AKT1 and diacylglycerol kinase alpha (DGKα), these innovations offer new strategies for cancer treatment, particularly in cases of resistance to conventional therapies.

Posterior reversible encephalopathy syndrome (PRES) is an uncommon neurological condition characterized by reversible subcortical vasogenic edema that primarily affects the posterior areas of the brain. Subcortical vasogenic edema resulting from endothelial injury and hypertension is the pathogenesis. Here, we present a 23-year-old female patient with systemic lupus erythematosus (SLE) and lupus nephritis who developed PRES following Rituximab (a monoclonal anti-CD-20 antibody) administration.

Thoracolumbar fractures: Factors predicting failure of percutaneous short- and long-segment posterior fixation.

Brain Spine

December 2024

Orthopedic Surgery Department, Unidade Local de Saúde de Braga, Portugal - Sete Fontes, São Victor, 4710-243, Braga, Portugal.

Introduction: Thoracolumbar (TL) transition trauma is frequent and challenging. Although short- (SSPF) and long-segment posterior fixation (LSPF) are its mainstay treatment, little is known about their failure rates and reasons behind it.

Research Question: understand why TL instrumentations fail and what factors influence it.

Background: Resolvin D2 (RvD2), which exhibits anti-inflammatory properties, is neuroprotective. This study aimed to ascertain the potential of serum RvD2 level as a prognostic predictor of moderate-to-severe traumatic brain injury (msTBI).

Methods: In this prospective cohort study, serum RvD2 levels were measured in 136 patients with msTBI and 100 healthy controls.
