In the study, 1,400 individuals were assessed multiple times between ages of 36 and 69 for level of physical activity. They were quantified as not active, moderately active, and most active. Cognition measurements in later life showed a dose-response relationship between sustained levels of physical activity and later-life cognition status.

Maternal immunization with 2 doses of vaccine was 97% and 53% effective against infant hospitalization from delta and omicron variants, respectively. The effectiveness of the vaccine in preventing infant hospitalization declined by nearly 20% after 16 weeks. Receiving the second dose in the third trimester yielded the greatest benefit.

The University of Virginia researchers used healthy mice and mice genetically engineered to lack aryl hydrocarbon receptor (AHR) in CD4-positive T-cells, an immune cell type implicated in MS, in the first set of experiments. These animals were subjected to the standard protocol for inducing an MS-like disease called experimental autoimmune encephalomyelitis (EAE). The results showed that mice lacking AHR had the same time to disease onset and peak clinical severity as healthy mice, but recovered faster in the chronic phase. The difference in recovery was only observed when the mutant mice were housed separately from their healthy counterparts, according to the researchers. The team hypothesized that this was due to microbiome differences that were only apparent when the mice lived separately and did not influence each other’s microbiomes.

Multiple studies’ pooled data revealed a significantly increased risk of Parkinson’s when combined with bullous pemphigoid, a rare skin condition, inflammatory bowel disease (IBD), or Sjögren’s syndrome. Immune response impairment has been linked to Parkinson’s disease in a growing body of evidence. Indeed, some studies have suggested that the neurodegenerative disease may be exacerbated by autoimmune processes, which occur when the immune system incorrectly attacks and destroys healthy tissue.

The results of these trials show that vitamin D reduced the risk of diabetes progression by 3% to 18% after three years, with serum 25-hydroxy D levels of at least 125 nmol/L showing the greatest benefit. Vitamin D was also associated with a 30% increase in the likelihood of returning to normal glucose regulation.

This observational study compared IV ketamine (47) to IN esketamine (15) in 62 adults suffering treatment-resistant depression. Response was measured using the QIDS-SR tool. The results? The two formulations were comparable in terms of change between baseline and endpoint QIDS-SR and response rates. However, IV ketamine generated benefits with fewer treatments.
