Purpose Of Review: Benign prostatic hyperplasia (BPH) is prevalent in nearly 70% of men over the age of 60, leading to significant clinical challenges due to varying symptom presentations and treatment responses. The decision to undergo surgical intervention is not straightforward; the American Urological Association recommends consideration of surgical treatment after inadequate or failed response to medical therapy. This review explores the role of artificial intelligence (AI), including machine learning and deep learning models, in enhancing the decision-making processes for BPH management.

The abyssomicins are a structurally intriguing family of bioactive natural products that include compounds with potent antibacterial, antitumour and antiviral activities. The biosynthesis of the characteristic abyssomicin spirotetronate core occurs an enzyme-catalysed intramolecular Diels-Alder reaction, which proceeds one of two distinct stereochemical pathways to generate products differing in configuration at the C15 spirocentre. Using the purified spirotetronate cyclases AbyU (from abyssomicin C/atrop-abyssomicin C biosynthesis) and AbmU (from abyssomicin 2/neoabyssomicin biosynthesis), in combination with synthetic substrate analogues, here we show that stereoselectivity in the spirotetronate-forming [4 + 2]-cycloaddition is controlled by a combination of factors attributable to both the enzyme and substrate.

Multisystem inflammatory syndrome in children (MIS-C) is a severe, post-infectious sequela of SARS-CoV-2 infection, yet the pathophysiological mechanism connecting the infection to the broad inflammatory syndrome remains unknown. Here we leveraged a large set of samples from patients with MIS-C to identify a distinct set of host proteins targeted by patient autoantibodies including a particular autoreactive epitope within SNX8, a protein involved in regulating an antiviral pathway associated with MIS-C pathogenesis. In parallel, we also probed antibody responses from patients with MIS-C to the complete SARS-CoV-2 proteome and found enriched reactivity against a distinct domain of the SARS-CoV-2 nucleocapsid protein.

The Diels-Alder reaction is one of the most effective methods for the synthesis of substituted cyclohexenes. The development of protein catalysts for this reaction remains a major priority, affording new sustainable routes to high value target molecules. Whilst a small number of natural enzymes have been shown capable of catalysing [4 + 2] cycloadditions, there is a need for significant mechanistic understanding of how these prospective Diels-Alderases promote catalysis to underpin their development as biocatalysts for use in synthesis.

Article Synopsis
  • Vitamin B12 is essential for blood cell formation and nerve insulation, and its deficiency can lead to neurological issues despite normal blood levels, as seen in a patient with symptoms like tremor and cognitive decline.
  • Researchers discovered an autoantibody against the transcobalamin receptor (CD320) that hinders vitamin B12 uptake in the brain, resulting in low levels found in cerebrospinal fluid even when blood levels appear normal.
  • The study suggests this autoimmune condition can be treated with immunosuppressive therapy and high-dose vitamin B12, and highlights the importance of recognizing how B12 transport differs in various tissues, which could improve diagnosis and treatment strategies for similar neurological disorders.

Article Synopsis
  • The rise of autoimmune diseases calls for new therapies, but there's a lack of long-term evaluation methods for these treatments.
  • Researchers used advanced techniques to analyze the unique patterns of autoantibodies in individuals, identifying stable "autoreactomes" that serve as immunological fingerprints.
  • Their findings suggest that therapies targeting B cell maturation antigen (BCMA) can significantly change these autoreactomes, implying that BCMA-based treatments might be effective for difficult-to-treat autoimmune conditions.

Article Synopsis
  • The study explores trends in surgeon compensation for endoscopic treatments of benign prostatic hyperplasia (BPH) in Canada, focusing on reimbursement changes from 2010 to 2023.
  • Seven out of ten provinces reimburse laser BPH surgery at the same rate as traditional TURP procedures, with average reimbursement varying significantly by province.
  • It was found that TURP reimbursements have not increased in line with inflation or the average salaries of working individuals, which may lead to disparities in treatment availability and hinder the adoption of new surgical techniques.
