Factors Associated With Lack of Long-Term Follow-Up Data After Global Cardiac Surgery Missions.

Humanitarian medical missions attempt to lessen the burden of limited access to cardiac surgery in low- and middle-income countries. While organizations express difficulties obtaining follow-up information, there is currently little evidence to support the various assumptions for lack of data. This study examines the factors influencing long-term patient follow-ups on repeated short-term cardiac surgery missions across nine countries.

Type A Aortic Dissection with Antegrade Intimointimal Intussusception.

We describe a 60-year-old man with a history of hypertension who presented to an outside emergency department with chest pain and left lower extremity numbness and weakness. Computed tomography (CT) revealed Stanford type A aortic dissection (TAAD), and he was transferred to our institution for emergent open surgical repair. Review of the outside CT showed no dissection flap in the ascending aorta and a complex flap in the proximal descending thoracic aorta consistent with complex intimal transection at the sinotubular junction and intimointimal intussusception.

Sepsis, an adverse auto-immune response to an infection often causing life-threatening complications, results in the highest mortality and treatment cost of any illness in US hospitals. Several immune biomarker levels, including Interleukin 6 (IL-6), have shown a high correlation to the onset and progression of sepsis. Currently, no technology diagnoses and stratifies sepsis progression using biomarker levels.
