Autonomic responses to aerobic and resistance exercise in patients with chronic musculoskeletal pain: A systematic review.

Background: It is unknown whether patients with chronic musculoskeletal pain (CMP) show autonomic dysregulation after exercise, and the interventional effects of exercise on the autonomic dysregulation have not been elucidated. The objectives of this study were to reveal acute autonomic responses after aerobic and resistance exercises and the interventional effects of both exercises on autonomic dysregulation in patients with CMP.

Methods: A systematic search using nine electronic databases was performed based on three key search terms: "chronic musculoskeletal pain," "autonomic nervous system," and "exercise.

Minimum detectable change in reaction time to the Posner task due to change in sustained attention.

[Purpose] Spatial attention evaluations are beneficial for patients with unilateral spatial neglect or dementia. Thus, such evaluations are crucial among these patients for determining functional disorder extents. The study aimed to determine minimal detectable changes in reaction time to the Posner task among healthy young participants for establishing spatial attention evaluation protocols.

A newly designed holder for grafts with four side branches used in total arch replacement.

Grafts with four presewn side branches have proven very useful for total aortic arch replacement worldwide. However, the four side branches often obscure the surgeon's view of the distal anastomotic site. Thus, we designed a holder for this graft, which sheaths and hides the graft body and branches, allowing the surgeon a better view of the distal anastomosis.

Injury to the tricuspid valve and membranous atrioventricular septum caused by huge calcified right ventricular myxoma: report of a case.

A 64-year-old female, admitted because of severe dyspnea on exertion and facial edema, showed echocardiographic findings of a large tumor in the right ventricle (RV). Echocardiography revealed a cardiac mass extending from the RV across the tricuspid valve into the right atrium, synchronized with the cardiac cycle, and severe tricuspid regurgitation was apparent. The mass was removed under cardiopulmonary bypass.

Pathogenetic significance of myxomatous degeneration in fenestration-related massive aortic regurgitation.

Background: Aortic valvular regurgitation has several mechanisms and the present study investigated its clinicopathological correlations with aortic valve fenestration.

Methods And Results: Six male patients with massive regurgitation and enlarged fenestrations or ruptured fenestrated fibrous cords underwent aortic valve replacement. The clinicopathological features showed many similarities.

Echocardiographic and surgical findings of spontaneous avulsion of the aortic valve commissure.

Spontaneous detachment of the aortic valve commissure (ie, avulsion of a commissure) is a rare cause of acute massive aortic regurgitation that follows a rapidly deteriorating clinical course. The aortic valve commissure between the non-coronary and right coronary cusps detached from the aortic wall in a 79-year old man with ascending aortic aneurysm. Emergency aortic valve replacement and aneurysmoplasty were successfully performed; histopathology of the aorta and aortic valve showed cystic medial necrosis and myxomatous degeneration, respectively.
