Variants at the GBA locus, encoding glucocerebrosidase, are the strongest common genetic risk factor for Parkinson's disease (PD). To understand GBA-related disease mechanisms, we use a multi-part-enrichment proteomics and post-translational modification (PTM) workflow, identifying large numbers of dysregulated proteins and PTMs in heterozygous GBA-N370S PD patient induced pluripotent stem cell (iPSC) dopamine neurons. Alterations in glycosylation status show disturbances in the autophagy-lysosomal pathway, which concur with upstream perturbations in mammalian target of rapamycin (mTOR) activation in GBA-PD neurons.

Article Synopsis
  • The study evaluated the metyrapone short test for assessing the hypothalamic-pituitary-adrenal (HPA) axis's function in patients with potential adrenal insufficiency.
  • 44 patients were recruited and divided into response groups based on their 11-deoxycortisol levels, with various analytical methods utilized for metabolite profiling.
  • Results showed distinct hormonal differences between the groups and highlighted the test's high diagnostic accuracy, suggesting that liver metabolites may play a role in the HPA axis's acute stress response.

Background: Training of health profession students in telehealth is important to ensure proper implementation for healthcare delivery. This prospective study aimed to analyze the effects of didactic and experiential learning on knowledge, confidence, and attitudes of telehealth among health profession students (Survey 1). The perceptions of a mixed model telehealth platform were also considered among these students and community clients (Survey 2).

Obesity and type 2 diabetes (T2D) show an increased risk for a severe COVID-19 disease. Treatment with DPP4 inhibitor (DPP4i) results in reduced mortality and better clinical outcome. Here, we aimed to identify potential mechanisms for the observed DPP4i effect in COVID-19.

Objective: To assess the long-term efficacy and safety of erenumab in the subgroup of patients with chronic migraine (CM) in whom prior preventive treatments had failed (TF) (≥1, ≥2, and ≥3 TF medication categories) and never failed (preventive naïve or prior preventive treatments had not failed), using the data from a 52-week, open-label treatment period (OLTP) of the parent study.

Background: Erenumab is a fully human monoclonal antibody that selectively binds to and inhibits the canonical calcitonin gene-related peptide receptor. There are limited long-term data evaluating the efficacy and safety of erenumab in patients with CM in whom prior preventive treatments had failed.
