Glioblastoma multiforme (GBM) is a malignant primary brain tumor categorized as a Grade 4 astrocytic glioma by the World Health Organization (WHO). Some of the established risk factors of GBM include inherited genetic syndromes, body mass index, alcohol consumption, use of non-steroidal anti-inflammatory drugs (NSAIDs), and therapeutic ionizing radiation. Vascular anomalies, including local and peripheral thrombosis, are common features of GBM.

Background And Aim: Explicit diagnostic criteria for transient ischemic attack (TIA) (EDCT) have been recently proposed based on the assumption, that a migraine aura-like symptom is not typical for a TIA. However, migraine-like symptoms have been unexpectedly frequent in patients with confirmed ischemic stroke. This cross-sectional study aimed to field-test the EDCT to distinguish transient neurological symptoms caused by cerebral infarction from those caused by migraine aura.

Strong evidence suggests links between Parkinson's Disease (PD) and melanoma, as studies have found that people with PD are at an increased risk of developing melanoma and those with melanoma are at increased risk of developing PD. Although these clinical associations are well-established, the cellular and molecular pathways linking these diseases are poorly understood. Recent studies have found a previously unrecognized role for the neurodegeneration-associated protein alpha-synuclein (αSyn) in melanoma; the overexpression of αSyn promotes melanoma cell proliferation and metastasis.

Methodologies for source attribution (SA) of foodborne illnesses comprise a rapidly expanding suite of techniques for estimating the most important source or sources of human infection. Recently, the increasing availability of whole genome sequencing (WGS) data for a wide range of bacterial strains has led to the development of novel SA methods. These techniques utilize the unique features of bacterial genomes adapted to different host types and hence offer increased resolution of the outputs.

Multiple randomized controlled trials have demonstrated that dual antiplatelet therapy (DAPT) significantly reduces the risk of subsequent stroke as compared to aspirin monotherapy after high-risk transient ischemic attack (TIA) or minor ischemic stroke. We sought to evaluate the uptake of DAPT after high-risk TIA at a single center. We conducted a retrospective cohort study of consecutive TIA patients admitted via the Emergency Department (ED) of Bern University Hospital (1/1/2018-12/31/2019).

Background: Aging is a complex process that involves all tissues in an organism and shows sex dimorphism. While transcriptional changes in aging have been well characterized, the majority of studies have focused on a single sex and sex differences in gene expression in aging are poorly understood. In this study, we explore sex dimorphism in gene expression in aging mice across three tissues.

Article Synopsis
  • The study investigates how well population-based registries track long-term outcomes, especially metastatic recurrence, in women treated for nonmetastatic breast cancer.
  • It reviews 23 studies from 11 registries across 8 countries, finding that most data on recurrence are collected inconsistently and primarily for specific research projects rather than as part of standard procedures.
  • The authors conclude that cancer registries should enhance their data collection processes to include recurrence information, which is essential for understanding the prognosis of breast cancer survivors.
