Background: Cardiovascular disease is a cause of morbidity and mortality in organ transplant recipients. Cardiac surgery after organ transplantation is not uncommon in this population. We evaluated 30-day outcomes and long-term survival of abdominal transplant recipients undergoing cardiac surgery at our institution.
Methods: In all, 138 patients with previous kidney, kidney-pancreas, and liver transplants underwent cardiac surgery from 2000 to 2016. Propensity score (ratio 1:3) matched 115 abdominal transplant with 345 patients undergoing cardiac surgery without a history of abdominal transplant. They were matched for type and year of cardiac surgery, age, sex, body mass index, history of diabetes mellitus, and creatinine level before cardiac surgery.
Results: Median time from abdominal transplant to cardiac surgery was 7 years (interquartile range, 3 to 12 years). Perioperative variables, including surgery and cardiopulmonary bypass time, aortic cross-clamp and intubation time, and intensive care unit stay did not differ between the groups. Hospital length of stay and rate of 30-day hospital readmissions did not differ between the groups. Patients with abdominal transplants had more strokes (4% versus 0.6%; p = 0.005) within 30 days after surgery. There were no differences in renal failure, bleeding, site infections, atrial fibrillation, and pneumonia between the groups. Five patients (4%) died within 30 days after surgery in the abdominal transplant group (4 kidneys, 1 liver, 0 kidney-pancreas), and 7 patients (2%) died in the nontransplanted group (p = 0.24).
Conclusions: Previous history of abdominal transplant is associated with an increased 30-day incidence of stroke after cardiac surgery. Abdominal transplant does not affect 30-day mortality after cardiac surgery, whereas long-term survival is significantly reduced. Regular patient follow-up and prevention and early treatment of postoperative complications are key to patient survival.

Breast cancer is the leading cause of cancer-related morbidity and mortality among women worldwide, with bone being the most common site of all metastatic breast cancer. Bone metastases are often associated with pain and skeletal-related events (SREs), indicating poor prognosis and poor quality of life. Most current therapies for breast cancer bone metastasis primarily serve palliative purposes, focusing on pain management, mitigating the risk of bone-related complications, and inhibiting tumor progression.

Spinal cord trauma leads to the destruction of the highly organized cytoarchitecture that carries information along the axis of the spinal column. Currently, there are no clinically accepted strategies that can help regenerate severed axons after spinal cord injury (SCI). Hydrogels are soft biomaterials with high water content that are widely used as scaffolds to interface with the central nervous system (CNS).

Dietary sulfur amino acid restriction (SAAR) elicits various health benefits, some mediated by fibroblast growth factor 21 (FGF21). However, research on SAAR's effects on the heart is limited and presents mixed findings. This study aimed to evaluate SAAR-induced molecular alterations associated with cardiac remodeling and their dependence on FGF21.

Prosthetic valve endocarditis (PVE) is the medical term used to describe a focus of infection involving a valvular substitute within the heart. It is a significant concern in the field of cardiology, and the epidemiology of PVE has seen notable developments over the last five decades. The disease currently affects an older demographic and is becoming increasingly prevalent in patients with transcatheter-implanted valves.

The systemic inflammatory response after cardiopulmonary bypass has been widely studied. However, there is a paucity of studies that focus on the local inflammatory changes that occur in the pericardial cavity. The purpose of this study is to assess the inflammatory mediators in the pericardial fluid of patients undergoing cardiac surgery.
