Intracerebral hemorrhage (ICH) and perihematomal edema (PHE) are key imaging markers of primary and secondary brain injury in hemorrhagic stroke. Accurate segmentation and quantification of ICH and PHE can help with prognostication and guide treatment planning. In this study, we combined Swin-Unet Transformers with nnU-NETv2 convolutional network for segmentation of ICH and PHE on non-contrast head CTs.

Background: Glucocorticoids (GCs) are critical regulatory molecules in the body, commonly utilized in clinical practice for their potent anti-inflammatory and immunosuppressive properties. However, prolonged, high-dose GC therapy is frequently associated with femoral head necrosis, a condition known as glucocorticoid-induced osteonecrosis of the femoral head (GC-ONFH). Emerging evidence suggests that enhanced autophagy may mitigate apoptosis, thereby protecting osteoblasts from GC-induced damage and delaying the progression of ONFH.

Unlabelled: Patients with severe traumatic brain injury (STBI) often experience an abnormal hemostasis that contributes to mortality and unfavorable neurological outcomes.

Objectives: We aimed to analyze epidemiologic, clinical, and laboratory factors associated with mortality in patients with STBI during the first 48 h after in-hospital admission.

Methods: We performed an observational retrospective study of STBI patients with associated extracranial trauma [defined as Injury Severity Score (ISS) ≥ 16 with an Abbreviated Injury Scale (AIS) head and neck ≥ 3 and Glasgow Coma Scale (GCS) ≤ 8] admitted to a Level II trauma center over seven years (2015-2021).

Traumatic cerebrospinal fluid (CSF) leakage from skull base fractures increases the risk of bacterial meningitis, which is associated with a high mortality rate in adults, and commonly results in severe neurological outcomes. While most cases of CSF leakage occur within three months post-injury and generally resolve spontaneously, delayed-onset meningitis remains a challenging complication. Herein, we report a rare case of severe bacterial meningitis with an intraventricular abscess one year following a frontal skull base fracture, despite no CSF leak.

Multiple sclerosis (MS) falls within the spectrum of central nervous system (CNS) demyelinating diseases that may lead to permanent neurological disability. Fundamental to the diagnosis and clinical surveillance is magnetic resonance imaging (MRI) that allows for the identification of T2-hyperintensities associated with autoimmune injury that demonstrate distinct spatial distribution patterns. Here, we describe the clinical experience of a 31-year-old, right-handed, White man seen in consultation at The University of Texas Southwestern Medical Center in Dallas, Texas, following complaints of headaches that began after head trauma related to military service.

Biomechanical perspectives on traumatic brain injury in the elderly: A comprehensive review.

Prog Biomed Eng (Bristol)

January 2025

Tehran University of Medical Sciences, Hassan-Abad Square, Imam-Khomeini Ave., Tehran, 11365-3876, Tehran, 1416753955, Iran (the Islamic Republic of).

Traumatic brain injuries (TBIs) pose a significant health concern among the elderly population, influenced by age-related physiological changes and the prevalence of neurodegenerative diseases. Understanding the biomechanical dimensions of TBIs in this demographic is vital for developing effective preventive strategies and optimizing clinical management. This comprehensive review explores the intricate biomechanics of TBIs in the elderly, integrating medical and aging studies, experimental biomechanics of head tissues, and numerical simulations.

Objective: Older adults have an increased risk of developing persistent cognitive complaints after mild traumatic brain injury (mTBI). Yet, studies exploring which factors protect older adults with mTBI from developing such complaints are rare. It has been suggested that one such factor may be cognitive reserve (CR), but it is unknown how CR influences cognition in this patient category.

Priority Clinical Actions for Outpatient Management of Nonhospitalized Traumatic Brain Injury.

J Neurotrauma

January 2025

Zuckerberg San Francisco General Hosptial and Trauma Center, University of California, San Francisco, San Francisco, California, USA.

Outpatient care following nonhospitalized traumatic brain injury (TBI) is variable, and often sparse. The National Academies of Sciences, Engineering, and Medicine's 2022 report on highlighted the need to improve the consistency and quality of TBI care in the community. In response, the present study aimed to identify existing evidence-based guidance and specific clinical actions over the days to months following nonhospitalized TBI that should be prioritized for implementation in primary care.

Cellular stressors inhibit general protein synthesis while upregulating stress response transcripts and/or proteins. Phosphorylation of the translation factor eIF2α by one of the several stress-activated kinases is a trigger for such signaling, known as the integrated stress response (ISR). The ISR regulates cell survival and function under stress.

Introduction: Neural stem cells from the subventricular zone (SVZ) neurogenic niche provide neurons that integrate in the olfactory bulb circuitry. However, in response to cortical injuries, the neurogenic activity of the SVZ is significantly altered, leading to increased number of neuroblasts with a modified migration pattern that leads cells towards the site of injury. Despite the increased neurogenesis and migration, many newly generated neurons fail to survive or functionally integrate into the cortical circuitry.

Background: The use of angioembolization as a first approach for treating severe, blunt splenic injuries has increased recently, yet evidence showing its superiority to immediate splenectomy is lacking. We compared the prognosis of angioembolization versus splenectomy in patients presenting hemodynamically unstable with high-grade, image-confirmed, blunt splenic injuries in a nationally representative dataset.

Methods: We queried the 2017-2022 Trauma Quality Improvement Program database for adults with blunt splenic injury abbreviated injury scale = 4-5, with arrival systolic blood pressure <90 mm Hg, and treated with either angioembolization or splenectomy <6 hours of arrival after a computed tomography scan.
