This review describes our current understanding of the role of the mitochondria in the repurposing of the anti-diabetes drugs metformin, gliclazide, GLP-1 receptor agonists, and SGLT2 inhibitors for additional clinical benefits regarding unhealthy aging, long COVID, mental neurogenerative disorders, and obesity. Metformin, the most prominent of these diabetes drugs, has been called the "Drug of Miracles and Wonders," as clinical trials have found it to be beneficial for human patients suffering from these maladies. To promote viral replication in all infected human cells, SARS-CoV-2 stimulates the infected liver cells to produce glucose and to export it into the blood stream, which can cause diabetes in long COVID patients, and metformin, which reduces the levels of glucose in the blood, was shown to cut the incidence rate of long COVID in half for all patients recovering from SARS-CoV-2.

Per- and polyfluoroalkyl substances (PFAS) exhibit widespread global distribution, extending to remote regions including Antarctica. Despite potential adverse effects on seabirds, PFAS exposure among Antarctic penguins remains poorly studied. We investigated the occurrence of 29 PFAS compounds in feathers and excreta of Gentoo penguins (Pygoscelis papua) from Fildes Bay, Antarctica.

Our review summarizes the diagnostic accuracy of plasma and cerebrospinal fluid (CSF) phosphorylated tau 217 (p-tau217) in detecting amyloid and tau pathology on positron emission tomography (PET). We systematically reviewed studies that reported the diagnostic accuracy of plasma and CSF p-tau217, searching MEDLINE/PubMed, Scopus, and Web of Science through August 2024. The accuracy of p-tau217 in predicting amyloid and tau pathology on PET was evaluated in 30 studies.

Article Synopsis
  • Late-onset psychosis (LOP) is a complex and poorly understood condition that could stem from late-onset schizophrenia or Alzheimer's disease, making accurate diagnosis crucial for effective treatment.
  • * This study used structural MRI data from 699 healthy individuals and 469 patients with schizophrenia or Alzheimer's to employ data-driven techniques, specifically K-means clustering, to differentiate between these conditions.
  • * Findings indicated that structural differences, such as larger right putamen volumes in schizophrenia patients, could help in distinguishing between AD and SCZ, highlighting the need for better diagnostic tools for LOP.
