Coronary artery fistulas are rare anomalies of the coronary arteries that may sometimes be totally asymptomatic and can be found incidentally during coronary arteriography later in adult life. We report the case of a 75-year-old man with such a fistula and describe our diagnostic approach. In addition, we review the literature on the etiology, epidemiology, the diagnostic modalities and treatment of coronary fistulas.

The BMT CTN 1703 phase III trial confirmed that graft-versus-host disease (GVHD) prophylaxis with post-transplantation cyclophosphamide (PTCy), tacrolimus (Tac), and mycophenolate mofetil (MMF) results in superior GVHD-free, relapse-free survival (GRFS) compared with Tac/methotrexate (MTX) prophylaxis. This companion study assesses the effect of these regimens on patient-reported outcomes (PROs). Using the Lee Chronic GVHD Symptom Score and PROMIS subscales (physical function, GI symptoms, social role satisfaction) as primary end points and hemorrhagic cystitis symptoms and Lee subscales as secondary end points, responses from English and Spanish speakers were analyzed at baseline and days 100, 180, and 365 after transplant.

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.

Mitochondrial endonuclease G (EndoG) contributes to chromosomal degradation when it is released from mitochondria during apoptosis. It is presumed to also have a mitochondrial function because EndoG deficiency causes mitochondrial dysfunction. However, the mechanism by which EndoG regulates mitochondrial function is not known.

Methods: Patients with major depressive disorder, bipolar disorder and, schizophrenia and with comorbid obesity (n = 29) were assigned to a 12-week structured physical exercise program. Peripheral blood biomarkers of inflammation, oxidative stress, vascular mechanisms, and metabolic activity, as well as neurocognitive and functional performance were assessed twice, before and after intervention.
