AI Article Synopsis

  • The study compares amino acid PET scans and conventional MRI to predict overall survival in patients with recurrent high grade glioma undergoing bevacizumab therapy.
  • Five studies with 72 patients revealed that PET-positive patients had significantly lower median survival compared to PET-negative patients.
  • The findings suggest that AA-PET is more effective than RANO MRI in predicting overall survival, with higher sensitivity and area under the curve values.

Article Abstract

Purpose: To summarize evidence on the comparative value of amino acid (AA) PET and conventional MRI for prediction of overall survival (OS) in patients with recurrent high grade glioma (rHGG) under bevacizumab therapy.

Methods: Medical databases were screened for studies with individual data on OS, follow-up MRI, and PET findings in the same patient. MRI images were assessed according to the RANO criteria. A receiver operating characteristic curve analysis was used to predict OS at 9 months.

Results: Five studies with a total of 72 patients were included. Median OS was significantly lower in the PET-positive than in the PET-negative group. PET findings predicted OS with a pooled sensitivity and specificity of 76% and 71%, respectively. Corresponding values for MRI were 32% and 82%. Area under the curve and sensitivity were significantly higher for PET than for MRI.

Conclusion: For monitoring of patients with rHGG under bevacizumab therapy, AA-PET should be preferred over RANO MRI.

Background: Abnormal glucose metabolism in AD brains correlates with cognitive deficits. The glucose changes are consistent with brain thiamine (vitamin B1) deficiency. In animals, thiamine deficiency causes multiple AD-like changes including memory loss, neuron loss, brain inflammation, enhanced phosphorylation of tau, exaggerated plaque formation and elevated advanced glycation end products (AGE).

Background: Non-human primates (NHP) serve as an important bridge for testing therapeutic agents that have been previously shown to be effective in transgenic mouse models. Our earlier published data using an NHP model of sporadic AD-related pathology that develops abundant cerebral amyloid angiopathy (CAA), squirrel monkeys (SQMs), indicates that chronic treatment with TLR9 agonist, class B CpG ODN, safely ameliorates CAA while promoting cognitive benefits. In the present study, we intended to delineate alterations in brain metabolome induced by chronic CpG ODN administration in order to provide further insight into CpG ODN immunomodulatory capabilities.

Gut-derived lactic acid enhances tryptophan to 5-hydroxytryptamine in regulation of anxiety via .

Gut Microbes

The gut microbiota plays a pivotal role in anxiety regulation through pathways involving neurotransmitter production, immune signaling, and metabolic interactions. Among these, gut-derived serotonin (5-hydroxytryptamine, 5-HT), synthesized from tryptophan metabolism, has been identified as a key mediator. However, it remains unclear whether specific microbial factors regulate tryptophan metabolism to influence 5-HT production and anxiety regulation.

Antibiotics are a revolutionary discovery in modern medicine, enabling the successful treatment of bacterial infections that were once untreatable and deadly. Teixobactin, a "head-toside- chain" cyclodepsipeptide, shows great promise as a lead compound for developing new antibiotics to deal with multi-drug-resistant bacterial infections. The unique pharmacological profile and intriguing structural characteristics of teixobactin, including its unusual amino acid residues (three D-amino acids and L-allo-enduracididine), have drawn the attention of multiple research groups seeking to create new antibiotics with innovative mechanisms.

Various tubular diseases in patients with multiple myeloma (MM) are caused by monoclonal immunoglobulin light chains (LCs). However, the physicochemical characteristics of the disease-causing LCs contributing to the onset of MM-associated tubular diseases remain unclear. We herein report a rare case of MM-associated combined tubulopathies: non-crystalline light chain proximal tubulopathy (LCPT) and crystalline light chain cast nephropathy (LCCN).
