NaHS protects brain, heart, and lungs as remote organs from renal ischemia/reperfusion-induced oxidative stress in male and female rats.

Acute Kidney Injury (AKI) is frequently observed in hospitalized patients in intensive care units, often caused by renal ischemia-reperfusion injury (IRI). IRI disrupts the function of various 'remote organs' such as the lungs, pancreas, intestine, liver, heart, and brain through inflammation, oxidative stress, apoptosis, leukocyte infiltration, and increased urea and creatinine levels. Gender differences in renal IRI-induced injury are noted.

Ascertaining the prognostic role of cardiac resynchronisation therapy in cardiac sarcoidosis: A comparison with ischaemic cardiomyopathy.

Background: Cardiac Resynchronisation Therapy (CRT) has demonstrated short and long-term benefit in heart failure with reduced ejection fraction (HFrEF), including ischaemic (ICM) and non-ischaemic cardiomyopathy. However, there is a paucity of evidence regarding its role in cardiac sarcoidosis (CS).

Methods: Consecutive CS patients with CRT and baseline left ventricle ejection fraction (LVEF)≤40 referred to one specialist hospital in London between November 2008-March 2023 were retrospectively reviewed.

Using an Isolated Working Rat Heart Model to Test Donor Heart Preservation Strategies.

Optimization of donor heart preservation solutions has played a key role in reducing ischemia-reperfusion injury in donor hearts during organ retrieval, transportation, and transplantation. Previous work from our laboratory showed that the addition of glyceryl trinitrate and erythropoietin to donor heart preservation solutions could significantly improve cardiac functional recovery after prolonged cold storage and in donation after circulatory death hearts. This supplementation protocol has been implemented in clinical use in transplant units around Australia, Belgium, and the United Kingdom.

Sympathetic reinnervation in cardiac transplant recipients: Prevalence, time course, and association with long-term survival.

Background: Partial cardiac sympathetic reinnervation after cardiac transplant has been extensively investigated and evidenced. However, there have been no large-scale, long-term studies evaluating the prevalence, time-course, and association with long-term survival of sympathetic reinnervation of the heart.

Methods: Cardiac transplant recipients (n = 232) were recruited from outpatient clinic at a single transplant center in the United Kingdom.

Pathologist interrater reliability and clinical implications of elevated donor-derived cell-free DNA beyond heart transplant rejection, on behalf of the GRAfT investigators.

Background: There is significant variability among pathologists in the histopathological interpretation of the endomyocardial biopsy (EMB) for acute cellular rejection (ACR), and assessment of variability in the interpretation of antibody-mediated rejection (AMR) has not been reported. In contemporary practice, the strategy of allograft surveillance with donor-derived cell-free DNA (dd-cfDNA) compared to EMB has not been compared with a focus on long-term clinical outcomes beyond acute rejection (AR).

Methods: The Genomic Research Alliance for Transplantation is a multicenter, prospective cohort study that enrolled patients from 2015 to 2020.

A latent Axin2/Scx progenitor pool is the central organizer of tendon healing.

A tendon's ordered extracellular matrix (ECM) is essential for transmitting force but is also highly prone to injury. How tendon cells embedded within and surrounding this dense ECM orchestrate healing is not well understood. Here, we identify a specialized quiescent Scx/Axin2 population in mouse and human tendons that initiates healing and is a major functional contributor to repair.

Outcomes of cardiac resynchronization therapy (CRT) in cardiac sarcoidosis patients with a range of ejection fractions.

Aims: In cardiac sarcoidosis (CS) patients, the benefit of cardiac resynchronization therapy (CRT) remains unclear. We sought to assess the short-term and long-term effects of CRT in CS patients with a range of left ventricular (LV) ejection fractions (LVEFs).

Methods: Consecutive CS patients with heart failure with reduced ejection fraction (HFrEF; LVEF ≤ 40%), mildly reduced ejection fraction (HFmrEF; LVEF 41%-49%) and preserved ejection fraction (HFpEF; LVEF ≥ 50) treated with CRT under the care of a tertiary UK centre between 2008 and 2023 were reviewed.

Venous Thromboembolism after Hospital Discharge: Temporal Trends in Baseline Characteristics, Prevention, Treatment, and 90-day Outcomes.

Venous thromboembolism (VTE) after hospital discharge poses a serious health risk. Assessments of patient characteristics, prophylaxis, treatment, outcomes, and over time changes lack consistency. Data on 16,901 hospitalized patients in the Registro Informatizado Enfermedad TromboEmbolica registry (2003-2022) were analyzed to evaluate trends in baseline characteristics, prophylaxis, treatments, and 90-day outcomes among medical (6,218) and surgical (10,683) patient cohorts.

Zinc finger nuclease-mediated gene editing in hematopoietic stem cells results in reactivation of fetal hemoglobin in sickle cell disease.

BIVV003 is a gene-edited autologous cell therapy in clinical development for the potential treatment of sickle cell disease (SCD). Hematopoietic stem cells (HSC) are genetically modified with mRNA encoding zinc finger nucleases (ZFN) that target and disrupt a specific regulatory GATAA motif in the BCL11A erythroid enhancer to reactivate fetal hemoglobin (HbF). We characterized ZFN-edited HSC from healthy donors and donors with SCD.

Outcomes of frail patients undergoing high-dose chemotherapy and autologous stem cell transplantation for multiple myeloma.

In patients with multiple myeloma (MM) not-eligible for autologous haematopoietic cell transplantation (autoHCT), a simplified frailty index (SFI) identifies frail patients at risk for poor outcomes, but data are limited for transplant-eligible patients. In this registry-based retrospective study, we used an adapted version of the SFI to determine the prevalence of frailty in patients ≥65 years of age with MM undergoing autoHCT. Out of 5563 patients, 37.

The burden of COVID-19 mortality among solid organ transplant recipients in the United States.

Solid organ transplant recipients (SOTRs) have a heightened risk of adverse coronavirus disease 2019 (COVID-19) outcomes because of immunosuppression and medical comorbidity. We quantified the burden of COVID-19 mortality in United States (US) SOTRs. A sample of deaths documented in the US solid organ transplant registry from June 2020 through December 2022 was linked to the National Death Index to identify COVID-19 deaths and weighted to represent all SOTR deaths during the study period.

Donor age over 55 is associated with worse outcome in lung transplant recipients with idiopathic pulmonary fibrosis.

Background: Lung transplantation (LTx) remains the only efficient treatment for selected patients with end-stage pulmonary disease. The age limit for the acceptance of donor organs in LTx is still a matter of debate. We here analyze the impact of donor organ age and the underlying pulmonary disease on short- and long-term outcome and survival after LTx.
