Nonsense suppressor transfer RNAs (tRNAs) or AntiCodon-Edited tRNAs (ACE-tRNAs) have long been envisioned as a therapeutic approach to overcome genetic diseases resulting from the introduction of premature termination codons (PTCs). The ACE-tRNA approach for the rescue of PTCs has been hampered by ineffective delivery through available modalities for gene therapy. Here we have screened a series of ACE-tRNA expression cassette sequence libraries containing >1800 members in an effort to optimize ACE-tRNA function and provide a roadmap for optimization in the future.

We describe two locally acquired cases of Mycobacterium ulcerans infection (Buruli ulcer) in the town of Batemans Bay on the east coast of New South Wales (NSW), Australia, 150 km north of Eden, the only other place in NSW where Buruli ulcer has likely been locally acquired. Genomic analysis showed that the bacterial isolates from the cases were identical but belonged to a phylogenetically distinct M. ulcerans clade that was most closely related to the isolate from the earlier case in Eden to the south.

Article Synopsis
  • The study investigates how race and ethnicity influence antibiotic usage among hospitalized children, utilizing data from over 846,000 inpatient visits in 2022 across the Pediatric Health Information System.
  • Findings indicate that Non-Hispanic Black children were less likely to receive antibiotics compared to Non-Hispanic White children, while Non-Hispanic Native Hawaiian/Other Pacific Islander children had a higher likelihood of receiving them.
  • The authors suggest that hospitals should re-evaluate their policies regarding antibiotic prescriptions to address these disparities, and further research is needed to better understand the factors contributing to these variations in treatment.

Depression, disrupted sleep and pain are common comorbidities in sickle cell disease. We tested (1) if these comorbidities are associated with attention/executive functioning, processing speed and instrumental activities of daily living (IADLs), which describe complex skills that support independence, and (2) if cognitive symptoms mediate the relationship between comorbidities and IADLs. Participants (n = 2417) completed patient-reported outcome measures through the Sickle Cell Disease Implementation Consortium.

Article Synopsis
  • - Human alpha-defensin antimicrobial peptides, specifically human neutrophil peptide 1 (HNP1) and human defensin 5 (HD5), significantly inhibit the effectiveness of adeno-associated virus (AAV2) vectors used in gene therapy by blocking infection and preventing the virus from reaching the nucleus.
  • - HD5 stops AAV2 from binding to cells, while HNP1 does not, but both defensins interfere with key viral processes that are necessary for the virus's success in infecting cells.
  • - These findings suggest a shared mechanism of action among alpha-defensins in neutralizing various non-enveloped viruses, which could lead to advancements in developing more effective gene therapy vectors that can overcome innate immune barriers.
