Background: Improved survival of heart transplant (HTx) recipients and increased acceptance of higher risk donors allows development of late pathology. However, there are few data to guide surgical options. We evaluated short-term outcomes and mortality to guide pre-operative assessment, planning, and post-operative care.
Methods: Single centre, retrospective review of 912 patients who underwent HTx from February 1984 - June 2012, identified 22 patients who underwent subsequent cardiac surgery. Data are presented as median (IQR).
Results: Indications for surgery were coronary allograft vasculopathy (CAV) (n=10), valvular disease (n=6), infection (n=3), ascending aortic aneurysm (n=1), and constrictive pericarditis (n=2). There was one intraoperative death (myocardial infarction). Hospital stay was 10 (8-21) days. Four patients (18%) returned to theatre for complications. After cardiac surgery, survival at one, five and 10 years was 91±6%, 79±10% and 59±15% with a follow-up of 4.6 (1.7-10.2) years. High pre-operative creatinine was a univariate risk factor for mortality, HR=1.028, (95%CI 1.00-1.056; p=0.05). A time dependent Cox proportional hazards model of the risk of cardiac surgery post-HTx showed no significant hazard; HR=0.87 (95%CI 0.37-2.00; p=0.74).
Conclusions: Our experience shows cardiac surgery post-HTx is associated with low mortality, and confirms that cardiac surgery is appropriate for selected HTx recipients.

Objective: Malalignment following cervical spine deformity (CSD) surgery can negatively impact outcomes and increase complications. Despite the growing ability to plan alignment, it remains unclear whether preoperative goals are achieved with surgery. The objective of this study was to assess how good surgeons are at achieving their preoperative goal alignment following CSD surgery.

Mitochondrial DNA (mtDNA) is highly polymorphic, and host mtDNA variation has been associated with altered cancer severity. To determine the basis of this mtDNA-cancer association, we analyzed conplastic mice with the C57BL/6J (B6) nucleus but two naturally occurring mtDNA lineages, and , where mitochondria generate more oxidative phosphorylation (OXPHOS)-derived reactive oxygen species (mROS). In a cardiac transplant model, Foxp3+ T regulatory (Treg) cells supported long-term allograft survival, whereas Treg cells failed to suppress host T effector (Teff) cells, leading to acute rejection.

Following myocardial infarction (MI), the accumulation of CD86-positive macrophages in the ischemic injury zone leads to secondary myocardial damage. Precise pharmacological intervention targeting this process remains challenging. This study engineered a nanotherapeutic delivery system with CD86-positive macrophage-specific targeting and ultrasound-responsive release capabilities.

Objective: To investigate gender disparities in applications and admissions to the medical residency programs in Peru, focusing on differences in application and admission proportions between male and female.
Methods: We conducted a cross-sectional study to assess the proportions of female applicants and admissions to medical residency programs in Peru from 2016 to 2023. Bayesian multilevel linear models were employed, incorporating random intercepts and slopes by specialty to account for variability across specialties.

Background: The deep inferior epigastric perforator (DIEP) flap is currently the gold standard for autologous breast reconstruction. In cases where the DIEP is contraindicated, the profunda artery perforator (PAP) flap is now the preferred second-line option in our institution. The PAP flap poses unique challenges to the reconstructive surgeon, especially in Asian women with low body mass index (BMI).
