Multi-Omic Atlas reveals cytotoxic phenotype and ROS-linked metabolic quiescence as key features of CTL-resistant HIV-infected CD4 T-cells.

Cytotoxic T-lymphocytes (CTL) exert sustained pressure on reservoirs of HIV-infected cells that persist through years of antiretroviral therapy (ART). This selects for latently infected cells, but also potentially for cells that express HIV but possess intrinsic CTL resistance. We demonstrate that such resistance exists in HIV-infected CD4 T-cells that survive rigorous CTL attack and map CTL susceptibility to cell identities and states defined by single-cell multi-omics and functional metabolic profiling.

Case report: First reported case of spondylodiscitis caused by Gemella morbillorum in South Africa.

Pyogenic spondylodiscitis is an uncommon but important clinical condition that often requires medical and/or surgical management. We report a case of spondylodiscitis caused by a rare pathogen, Gemella morbillorum. To date, worldwide, only six such cases of confirmed spondylodiscitis infection with this rare pathogen have been documented, and this is the first reported case in South Africa.

Pediatric oncology nutritional practices in high-income countries: A survey from the International Society of Paediatric Oncology (SIOP).

Background: Optimal nutrition in pediatric oncology can influence cancer-related outcomes. To establish an understanding of nutrition practice and perceptions of best practice, we queried nutrition providers practicing in pediatric oncology care centers in high-income countries.

Methods: An electronic, multidisciplinary, cross-sectional survey of nutrition practices was conducted among pediatric oncology nutrition practitioners.

Transcription of HIV-1 at sites of intact latent provirus integration.

HIV-1 antiretroviral therapy is highly effective but fails to eliminate a reservoir of latent proviruses, leading to a requirement for life-long treatment. How the site of integration of authentic intact latent proviruses might impact their own or neighboring gene expression or reservoir dynamics is poorly understood. Here, we report on proviral and neighboring gene transcription at sites of intact latent HIV-1 integration in cultured T cells obtained directly from people living with HIV, as well as engineered primary T cells and cell lines.

Improving emergency department flow by introducing four interventions simultaneously. A quality improvement project.

Background: Emergency department (ED) crowding is a widespread issue with adverse effects on patient care and outcomes.

Local Problem: ED crowding exacerbates wait times and compromises patient care, prompting opportunities for internal process improvement.

Method: Over one week, the ED flow project team implemented four interventions, including an additional triage station, to optimize patient flow.
