Emerging infectious diseases are increasingly recognized as a significant threat to global biodiversity conservation. Elucidating the relationship between pathogens and the host microbiome could lead to novel approaches for mitigating disease impacts. Pathogens can alter the host microbiome by inducing dysbiosis, an ecological state characterized by a reduction in bacterial alpha diversity, an increase in pathobionts, or a shift in beta diversity.

Background: Transfusion-dependent β-thalassaemia (TDT) is a severe disease, resulting in lifelong blood transfusions, iron overload, and associated complications. Betibeglogene autotemcel (beti-cel) gene therapy uses autologous haematopoietic stem and progenitor cells (HSPCs) transduced with BB305 lentiviral vector to enable transfusion independence.

Methods: HGB-212 was a non-randomised, multicentre, single-arm, open-label, phase 3 study of beti-cel in patients with TDT conducted at eight centres in France, Germany, Greece, Italy, the UK, and the USA.

The XVI-th Banff Meeting for Allograft Pathology was held in Banff, Alberta, Canada, from 19th-23rd September 2022, as a joint meeting with the Canadian Society of Transplantation. To mark the 30 anniversary of the first Banff Classification, pre-meeting discussions were held on the past, present, and future of the Banff Classification. This report is a summary of the meeting highlights that were most important in terms of their effect on the Classification, including discussions around microvascular inflammation and biopsy-based transcript analysis for diagnosis.

Article Synopsis
  • - The study compares the safety of narrow-spectrum vs. broad-spectrum antibiotics for treating community-acquired pneumonia (CAP) in healthy adults aged 18-64, revealing that broad-spectrum antibiotics have a higher risk of adverse drug events (ADEs).
  • - An analysis of 145,137 patients showed that broad-spectrum antibiotics like fluoroquinolones and β-lactams were linked to increased risks of issues such as nausea, diarrhea, and vulvovaginal infections compared to macrolide monotherapy.
  • - The findings highlight the need for better antimicrobial stewardship to encourage the careful use of antibiotics, particularly broad-spectrum ones, to minimize the risk of harmful side effects.

Article Synopsis
  • Gene therapy using elivaldogene autotemcel (eli-cel) has shown effectiveness in treating cerebral adrenoleukodystrophy but raises concerns about cancer risks.
  • Research analyzed blood and bone marrow samples from patients who received eli-cel to evaluate integration sites and other genetic factors.
  • Out of 67 patients treated, 7 developed hematologic cancers, with multiple instances linked to lentiviral vector insertions, though some patients successfully underwent stem cell transplantation and remained symptom-free.
