The relationship between performance validity testing, external incentives, and cognitive functioning in long COVID.

Introduction: Performance validity test (PVT) failures occur in clinical practice and at higher rates with external incentives. However, little PVT research has been applied to the Long COVID population. This study aims to address this gap.

Perineal lacerations and social media: can patients find reliable information on Instagram and TikTok?

Introduction And Hypothesis: Social media content related to patient experiences and education continues to grow. Information on how obstetric perineal lacerations are represented on social media is limited. Our goal is to characterize available social media content on obstetric perineal lacerations.

Emotional functioning in long COVID: Comparison to post-concussion syndrome using the Personality Assessment Inventory.

Recent studies on Long COVID found that patients report prominent emotional distress and significant correlations between distress and cognitive performance have been identified, raising the question of how to manage or treat these issues. To understand psychological functioning in Long COVID further, this study examined personality responses on the Personality Assessment Inventory (PAI) to compare psychological functioning in a Long COVID group with a post-concussion syndrome (PCS) group, a syndrome with a significant psychological component. Participants included 201 consecutive Long COVID outpatients (Mean age = 48.

Applicability, safety, and biological activity of regulatory T cell therapy in liver transplantation.

Regulatory T cells (Tregs) are a lymphocyte subset with intrinsic immunosuppressive properties that can be expanded in large numbers ex vivo and have been shown to prevent allograft rejection and promote tolerance in animal models. To investigate the safety, applicability, and biological activity of autologous Treg adoptive transfer in humans, we conducted an open-label, dose-escalation, Phase I clinical trial in liver transplantation. Patients were enrolled while awaiting liver transplantation or 6-12 months posttransplant.

A Rapamycin-Based GMP-Compatible Process for the Isolation and Expansion of Regulatory T Cells for Clinical Trials.

The concept of regulatory T cell (Treg)-based immunotherapy has enormous potential for facilitating tolerance in autoimmunity and transplantation. Clinical translation of Treg cell therapy requires production processes that satisfy the rigors of Good Manufacturing Practice (GMP) standards. In this regard, we report our findings on the implementation of a robust GMP compliant process for the expansion of clinical grade Tregs, demonstrating the feasibility of this developed process for the manufacture of a final product for clinical application.

Cell Therapy in Organ Transplantation: Our Experience on the Clinical Translation of Regulatory T Cells.

Solid organ transplantation is the treatment of choice for patients with end-stage organ dysfunction. Despite improvements in short-term outcome, long-term outcome is suboptimal due to the increased morbidity and mortality associated with the toxicity of immunosuppressive regimens and chronic rejection (1-5). As such, the attention of the transplant community has focused on the development of novel therapeutic strategies to achieve allograft tolerance, a state whereby the immune system of the recipient can be re-educated to accept the allograft, averting the need for long-term immunosuppression.

Avoiding room temperature storage and delayed cryopreservation provide better postthaw potency in hematopoietic progenitor cell grafts.

Background: Conditions for maintaining hematopoietic progenitor cells (HPCs) before cryopreservation remain controversial. An understanding of the impact of time and temperature during nonfrozen storage can contribute to the maintenance of the quality of products, improving transplantation outcomes. The objective of this study was to determine the influence on cell potency of thawed products from three sources of HPCs after prolonged storage at different temperatures before cryopreservation.

Flow cytometry assessment of apoptotic CD34+ cells by annexin V labeling may improve prediction of cord blood potency for engraftment.

Background: Nonviable CD34+ cells are commonly assessed by standard flow cytometry using the nuclear stain 7-aminoactinomycin D (7AAD). 7AAD, however, only detects necrotic and late apoptotic cells, not earlier apoptosis, which engraft poorly in animal models of cord blood (cord) transplantation. The standard method, therefore, may overestimate engraftment potency of cord units under certain conditions.
