Survival Among Patients With ERBB2-Positive Metastatic Breast Cancer and Central Nervous System Disease.
JAMA Netw Open
January 2025
Department of Neurosurgery and Brain Metastasis Center, Memorial Sloan Kettering Cancer Center, New York, New York.
Importance: Approximately one-third of patients with ERBB2 (formerly HER2 or HER2/neu)-positive (ERBB2+) metastatic breast cancer (MBC) develop brain metastasis. It is unclear whether patients with disease limited to the central nervous system (CNS) have different outcomes and causes of death compared with those with concomitant extracranial metastasis.
Objective: To assess overall survival (OS) and CNS-related mortality among patients with ERBB2+ breast cancer and a diagnosis of CNS disease by disease distribution (CNS only vs CNS plus extracranial metastasis).
Adverse Prehospital Events and Outcomes After Traumatic Brain Injury.
JAMA Netw Open
January 2025
Department of Emergency Medicine, The Ohio State University, Columbus.
Importance: While national guidelines recommend avoidance of hypoxia, hypotension, and hypocarbia in the prehospital care of traumatic brain injury (TBI), limited data validate the association of these adverse physiologic events with TBI outcomes.
Objective: To validate the associations of prehospital hypoxia, hypotension, and hypocarbia with TBI outcomes in a US national trauma network.
Design, Setting, And Participants: This cohort study examined data from 8 level I trauma centers and their affiliated ground and air emergency medical services (EMS) agencies in the Linking Investigations in Trauma and Emergency Services (LITES) Network from January 1, 2017, to June 30, 2021.
Proteomic Analyses in COVID-19-Associated Secondary Hemophagocytic Lymphohistiocytosis.
Crit Care Explor
February 2025
Center for Fundamental Immunology, Benaroya Research Institute, Seattle, WA.
Context: COVID-19 has been associated with features of a cytokine storm syndrome with some patients sharing features with the hyperinflammatory disorder, secondary hemophagocytic lymphohistiocytosis (sHLH).
Hypothesis: We hypothesized that proteins associated with sHLH from other causes will be associated with COVID-sHLH and that subjects with fatal COVID-sHLH would have defects in immune-related pathways.
Methods And Models: We identified two cohorts of adult patients presenting with COVID-19 at two tertiary care hospitals in Seattle, Washington in 2020 and 2021.
Upregulation of the MAP2K4 gene triggers endothelial-mesenchymal transition in COVID-19.
Mol Biol Rep
January 2025
Department of Molecular Biology and Genetics, Faculty of Art and Science, Tokat Gaziosmanpasa University, Tokat, 60200, Türkiye.
Background: SARS-CoV-2 infection is marked by an excessive inflammatory response, leading to elevated production of pro-inflammatory cytokines through activation of intracellular pathways like mitogen-activated protein kinase (MAPK). Viruses can use the MAPK signaling pathway to their advantage, but the relationship of this pathway to the severe SARS-CoV-2 period has not been fully elucidated. MAP2K4 is involved in the MAPK signaling pathway and affects cellular processes such as cell-cell junction, cell proliferation, differentiation and apoptosis.

Acta Neurochir (Wien)
January 2025
Department of Neurosurgery, LMU University Hospital, Ludwig-Maximilians-University Munich, Marchioninistrasse 15, 81377, Munich, Germany.
Purpose: Treatment strategies for space-occupying/symptomatic pineal cysts (PC) are still up for debate. In this study we present PC management, outcome data and risk factors for recurrence after surgery, focusing on microscopic/endoscopic procedures vs. stereotactic catheter implantation as alternative treatment concept to permanently drain PC into ventricles/cisterns.
