Nearly 10 years ago a definition was given by Dominici et al describing Mesenchymal Stem Cells as being plastic adherent, expressing CD73, CD90, CD105 and having the ability to differentiate into osteoblasts, adipocytes and chondrocytes. Since this time the expression “Mesenchymal Stem Cells” has been used to describe what we believe are multipotent cells.
However, many questions h…[more...]
Predictive Factors for Native AVF Complications in Dialysis Patients – A Prospective Study in a Public Hemodialysis Center
Aims: To evaluate the prevalence of arteriovenous fistula (AVF) complications in hospitalized patients on maintenance dialysis admitted for other reasons than vascular access problems and to assess the impact of known predisposing factors for each complication.
Materials and methods: In this prospective longitudinal, hospital-based, observational study we enrolled 218 dialysis patients with native AVF as vas…[more...]
The Evolution of Electrocardiographic Changes after Revascularization Therapy in Patients with ST Segment Elevation Myocardial Infarction
Methodology: The dynamics of both ST segment elevation and R wave amplitude was followed in 146 STEMI cases upon admission and after reperfusion therapy, in 3 different moments. Demographics, the symptom onset to presentation interval, co-morbidities, traditional risk factors, echocardiography findings, cardiovascular events and mortality during hospitalization were assessed.
Results: The changes…[more...]
The Distally Based Superficial Sural Artery Angiosome Flap Concept: Anatomy, Indications, Surgical Technique, Results, Complications and Technical Aspects to Minimize Complications
Matherial and method: The large series of cases published in the medical literature, innovations, technique modifications along with risk factors identification has been followed by this flap rise in popularity. 64 publications on the sural flap subject, in the international literature, were summarized in this study.
