Incidence, Risk Factors, and Outcomes of BK Hemorrhagic Cystitis in Hematopoietic Stem Cell Transplantation From HLA-Matched and Haploidentical Donors With Post-Transplant Cyclophosphamide.

BK hemorrhagic cystitis (BK-HC) is a common complication following hematopoietic stem cell transplantation (HSCT), particularly when posttransplant cyclophosphamide (PTCy) is used as graft-versus-host disease (GVHD) prophylaxis. However, comparative studies of BK-HC incidence in matched sibling donors (MSD) and unrelated donors (MUD) often include small haploidentical (HAPLO) donor cohorts and usually lack detailed information on disease evolution, coinfections, management and impact on outcomes. This study aimed to evaluate the incidence, risk factors, and outcomes in patients with hematologic malignancies undergoing HSCT from MSD, MUD, HAPLO donors using PTCy as GVHD prophylaxis.

Outcomes within 100 days of hematopoietic cell transplantation in pediatric patients: insights from an intensive care unit in Colombia.

Introduction: Hematopoietic cell transplantation (HCT) has become an essential therapeutic modality for pediatric patients with malignant and non-malignant conditions. Despite its effectiveness, many patients experience post-transplant complications often leading into life-threatening conditions requiring specialized care in a Pediatric Intensive Care Unit (PICU). This study aims to describe clinical characteristics associated with mortality in pediatric HCT patients who needed PICU care within 100 days post-transplant in a resource-limited country.

Peer learning and academic burnout mitigation in medical students: a mediation analysis.

Background: Academic Burnout (ABO) is prevalent among medical students and is characterized by mental and physical exhaustion, cynicism, and a sense of inadequacy. Informal Peer-Assisted Learning (IPAL) is recognized as an effective strategy to enhance student wellness and mitigate ABO by fostering collaborative learning and support without direct faculty oversight. This study evaluates the effectiveness of IPAL in reducing ABO, focusing on the mediation of the observed variables and its impact on student well-being.

The association of microorganisms with the algae is close and can be functionally interdependent. The Magellan Strait, a natural marine passage between the Atlantic and Pacific oceans, harbours extensive giant kelp forests.

Efficient synthesis of β-aminonitriles from arynes and imines in acetonitrile.

Multicomponent reactions are powerful strategies for synthesizing complex molecules in an efficient manner. In this work, we investigate a novel multicomponent reaction involving arynes, imines, and nitriles, leading to chiral β-aminonitriles. Notably, two new bonds (C-C and C-N) are formed in one step without the use of metal catalysts, showing the great potential of this transformation.

Bones or Stones: How Can We Apply Geophysical Techniques in Bone Research?

Some studies have used physical techniques for the assessment of bone structure and composition. However, very few studies applied multiple techniques, such as those described below, at the same time. The aim of our study was to determine the chemical and mineralogical/organic composition of bovine tibial bone samples using geophysical/geochemical reference techniques.

The effect of fuel (hydrogen vs. butane) on the formation of volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs) was evaluated for grilled horse meat (very low-fat and low-fat) cooking vertically. Gas chromatography-mass spectrometry was used to analyze PAHs and VOCs.

The expression of immune response genes in patients with chronic Chagas disease is shifted toward the levels observed in healthy subjects as a result of treatment with Benznidazole.

Introduction: Chagas disease, caused by the parasite infection, is a potentially life-threatening neglected tropical disease with a worldwide distribution. During the chronic phase of the disease, there exists a fragile balance between the host immune response and parasite replication that keeps patients in a clinically-silent asymptomatic stage for years or even decades. However, in 40% of patients, the disease progresses to clinical manifestations mainly affecting and compromising the cardiac system.

Longitudinal outcome over four decades of allogeneic stem cell transplantation: a single center experience.

This 45-year study (1978-2022) at a single institution evaluated HSCT outcomes and complications, emphasizing recent advances, with to provide insights into HSCT's evolving field and ongoing efforts to enhance patient outcomes. Involving 1707 patients, the study revealed an initial phase (1978-1987) with a limited activity that yielded modest outcomes, a nearly three-decade span (1988-2016) with a substantial increase in transplant activity, emphasizing umbilical cord blood transplantation (UCBT) for patients lacking a suitable matched sibling donor. In addition to a gradual increase in recipient age, significant improvement in outcomes emerged in the recent period (2017-2022), marked by UCBT replacement with haploidentical transplants, introduction of PTCY-based GVHD prophylaxis for all type of transplants, and increased use of conditioning regimens with thiotepa, busulfan, and fludarabine.
