Although refrigerated storage slows the metabolism of volunteer donor RBCs, which is essential in transfusion medicine, cellular aging still occurs throughout this in vitro process. Storage-induced microerythrocytes (SMEs) are morphologically-altered senescent RBCs that accumulate during storage and are cleared from circulation following transfusion. However, the molecular and cellular alterations that trigger clearance of this RBC subset remain to be identified.

Background: Unplanned and potentially avoidable readmission within 30 days post discharge is a major financial burden.

Aim: To use text-based electronic patient records to calculate the Charlson Comorbidity Index (CCI) score using a natural language processing technique to establish the feasibility and usefulness of the text-based electronic patient records in identifying patients at risk for unplanned readmission.

Methods: A retrospective review of electronic patient records for general and trauma surgery in a hospital in South Africa (2012-2022) was conducted using the LACE score.

Apoptotic cells are immunosuppressive, creating a barrier in cancer treatment. Thus, we investigated immune responses to dying tumor cells after therapy in the tumor draining lymph node (TDLN). A key population responsible for clearing tumor material in the TDLN was medullary sinus macrophages (MSMs).

Brain metastases frequently develop in patients with non-small cell lung cancer (NSCLC) and are a common cause of cancer-related deaths, yet our understanding of the underlying human biology is limited. Here we performed multimodal single-nucleus RNA and T cell receptor, single-cell spatial and whole-genome sequencing of brain metastases and primary tumors of patients with treatment-naive NSCLC. Chromosomal instability (CIN) is a distinguishing genomic feature of brain metastases compared with primary tumors, which we validated through integrated analysis of molecular profiling and clinical data in 4,869 independent patients, and a new cohort of 12,275 patients with NSCLC.

Article Synopsis
  • HIV-1 genome diversification is crucial for understanding viral evolution and disease progression, highlighting the need for improved detection methods to monitor the virus effectively.
  • The study introduces a new dual reporter sensor cell (DRSC) assay that enables high-content imaging to simultaneously detect HIV-1 infection and assess various viral characteristics at the single-cell level.
  • The DRSC assay enhances insights into HIV-1 functional heterogeneity and allows for analysis of crucial factors like viral fitness, co-receptor preference, and assembly processes, showcasing its potential for better understanding and managing HIV/AIDS.
