Randomized Controlled Trial
One-year Aerobic Interval Training Improves Endothelial Dysfunction in Patients with Atrial Fibrillation: A Randomized Trial.
Objective To evaluate the effects of one-year aerobic interval training on endothelial dysfunction in patients with atrial fibrillation. Methods Seventy-four patients with atrial fibrillation (53 men, 21 women; mean age 63±6 years old) were randomized into a 1-year continuous aerobic interval training (CT), 6-month detraining after 6 months of aerobic interval training (DT), or medical treatment only (MT) group. Aerobic interval training was performed 3 times a week for 1 year or 6 months, with an exercise intensity of 85-95% of the peak heart rate. ⋯ MT: 0.86±0.28 pg/mL, p=0.015). Conclusion One-year aerobic interval training improves endothelial dysfunction in patients with atrial fibrillation and is primarily associated with the reduction in circulating thrombogenic and pro-inflammatory factors. A definitive way to sustain these improvements is the long-term continuation of aerobic training.

Objective In general, surface ulceration in gastric gastrointestinal stromal tumor (GIST) is considered a malignant feature; however, the mechanism underlying its formation has not been evaluated in detail. In this study, we analyzed the factors involved in ulceration using resected specimens of gastric GIST. Methods A total of 48 samples were retrospectively analyzed. ⋯ Intraluminal growth pattern was strongly associated with ulceration (p=0.00019). After a multivariate analysis, the growth pattern was the only factor associated with ulceration of gastric GIST. Conclusion Although formation of surface ulceration in gastric GIST was partially associated with the degree of malignancy, the growth pattern was the most important factor associated with ulceration in gastric GIST.

Case Reports
Aplastic Anemia with Epstein-Barr Virus Reactivation after Anti-thymocyte Globulin Therapy.
Lymphoproliferative disorders and Epstein-Barr virus reactivation (EBV-LPDs) have various forms of onset, ranging from infectious mononucleosis-like syndrome (IM-like) to lymphoma, although whether or not IM-like progresses to lymphoma remains unclear. A 61-year-old man was diagnosed with aplastic anemia (AA). Polyclonal atypical B-lymphocytes were observed in the peripheral blood, and IM-like was diagnosed. ⋯ Rituximab was initiated but later discontinued because of severe acute respiratory syndrome coronavirus 2 infection. Pancytopenia due to AA exacerbation recurred. The patient ultimately died of multiple organ failure due to bacterial infection.
