One hundred thirty-four germ line PU.1 variants and the agammaglobulinemic patients carrying them.

Leukopoiesis is lethally arrested in mice lacking the master transcriptional regulator PU.1. Depending on the animal model, subtotal PU.

Cutaneous dysbiosis characterizes the post-allogeneic hematopoietic stem cell transplantation period.

Gut dysbiosis is linked to mortality and the development of graft-versus-host disease (GVHD) after hematopoietic stem cell transplantation (HSCT), but the impact of cutaneous dysbiosis remains unexplored. We performed a pilot observational study and obtained retroauricular and forearm skin swabs from 12 adult patients prior to conditioning chemotherapy/radiation, and at 1-week, 1-month and 3-months after allogeneic HSCT, and performed shotgun metagenomic sequencing. The cutaneous microbiome among HSCT patients was enriched for gram-negative bacteria such as E coli and Pseudomonas, fungi, and viruses.

Responses of an Coculture Alveolar Model for the Prediction of Respiratory Sensitizers (ALIsens) Following Exposure to Skin Sensitizers and Non-Sensitizers.

In recent years, a global increase in allergy incidence following chemical exposure has been observed. While the process of skin sensitization is well characterized through the adverse outcome pathway (AOP) framework, the immunological mechanisms underlying respiratory sensitization remain less well understood. Respiratory sensitizers are classified as substances of very high concern (SVHC) under the European Union (EU) regulation for the registration, evaluation, authorization and restriction of chemicals (REACH), emphasizing the importance of evaluating respiratory tract sensitization as a critical hazard.

Disparities in Access to Care in the Multimodal Treatment of Primary Nonmetastatic Liver Cancers and Their Impact on Patient Outcomes.

Background: Liver cancer incidence and mortality have been shown to differ by race, ethnicity, and geography. This study aims to analyze disparities in the multimodal treatment of liver cancers in Louisiana.

Methods: Cases of nonmetastatic liver cancer in Louisiana from 2010 to 2020 were obtained from the Louisiana Tumor Registry.

Psychological Challenges of Adults With Severe Mental Illness During the COVID-19 Pandemic.

The COVID-19 pandemic was an unprecedented global health crisis. Vulnerable populations with preexisting mental illness have been disproportionately burdened and may experience adverse mental health outcomes related to the COVID-19 pandemic. Our objective was to evaluate the association between COVID-19 diagnosis, known exposure to COVID-19, sheltering in place, symptom severity, psychological distress, and depression severity among adults with severe mental illness (SMI).
