Budesonide, Added to PTCy-Based Regimen, for Prevention of Acute GI GVHD After Allogeneic Stem Cell Transplantation.

Am J Hematol

January 2025

Hematopoietic Stem Cell Transplant and Cellular Therapy Program, Division of Hematology/Oncology, Department of Medicine, Chao Family Comprehensive Cancer Center, University of California Irvine, Irvine, California, USA.

Oral budesonide exerts local effects with negligible systemic glucocorticoid activity, due to rapid first-pass metabolism, therefore, could potentially be efficacious in preventing gastrointestinal (GI) acute GVHD (aGVHD). We explored the use of budesonide, added to posttransplant cyclophosphamide (PTCy), tacrolimus, and mycophenolate mofetil, for prevention of GI aGVHD after allogeneic hematopoietic stem cell transplantation (AHSCT) in a prospective observational study and treated 80 patients with a median age of 53 years (range 19-74). Results were compared with a publicly available CIBMTR dataset of 646 patients who received PTCy-based GVHD prophylaxis (CIBMTR Study # GV17-02) (control).

Article Synopsis
  • Cholinesterase (ChE) inhibitors are used for treating Alzheimer's symptoms, but hospitalization often includes anticholinergic medications that counteract these inhibitors.
  • A study analyzed the effect of high anticholinergic burden (ACB) on hospital length of stay (LOS) and 30-day readmissions for patients taking ChE inhibitors during their hospital stay.
  • Results showed that patients with high ACB experienced a significantly longer hospital stay (5.50 days vs 4.25 days), but the 30-day readmission rate difference was not statistically significant (6.8% vs 2.2%).

Introduction: Coronavirus 2019 (COVID-19) has had a devastating impact on mental health and access to addiction treatment in the United States, including in California, which resulted in the highest rates of emergency department visits (ED) for opioid poisoning in 2020. As California slowly returns to pre-pandemic normalcy, it remains uncertain whether the rates of opioid-related events have slowed down over time. We hypothesized that the number of opioid-related ED visits were exacerbated after the period of the COVID-19 pandemic and continue at a high rate in the present.

Probing Functional Allosteric States and Conformational Ensembles of the Allosteric Protein Kinase States and Mutants: Atomistic Modeling and Comparative Analysis of AlphaFold2, OmegaFold, and AlphaFlow Approaches and Adaptations.

J Phys Chem B

November 2024

Keck Center for Science and Engineering, Graduate Program in Computational and Data Sciences, Schmid College of Science and Technology, Chapman University, Orange, California 92866, United States.

This study reports a comprehensive analysis and comparison of several AlphaFold2 adaptations and OmegaFold and AlphaFlow approaches in predicting distinct allosteric states, conformational ensembles, and mutation-induced structural effects for a panel of state-switching allosteric ABL mutants. The results revealed that the proposed AlphaFold2 adaptation with randomized alanine sequence scanning can generate functionally relevant allosteric states and conformational ensembles of the ABL kinase that qualitatively capture a unique pattern of population shifts between the active and inactive states in the allosteric ABL mutants. Consistent with the NMR experiments, the proposed AlphaFold2 adaptation predicted that G269E/M309L/T408Y mutant could induce population changes and sample a significant fraction of the fully inactive I form which is a low-populated, high-energy state for the wild-type ABL protein.

Since early 2020, several SARS-CoV-2 variants of concern (VOCs) continue to emerge, evading waning antibody mediated immunity produced by the current Spike-alone based COVID-19 vaccines. This caused a prolonged and persistent COVID-19 pandemic that is going to enter its fifth year. Thus, the need remains for innovative next generation vaccines that would incorporate protective Spike-derived B-cell epitopes that resist immune evasion.
