Journal ArticleDOI
Autologous infusion of expanded mobilized adult bone marrow-derived CD34+ cells into patients with alcoholic liver cirrhosis.
Madhava Pai,Dimitris Zacharoulis,Miroslav Milicevic,Salah Helmy,Long R. Jiao,Nataša Levičar,Paul Tait,Michael S. Scott,Stephen B. Marley,Kevin Jestice,Maria Glibetic,Devinder S. Bansi,Shahid A. Khan,Despina Kyriakou,Christos Rountas,Andrew V. Thillainayagam,Joanna Nicholls,Steen Lindkaer Jensen,Jane F. Apperley,Myrtle Y. Gordon,Nagy A. Habib +20 more
TL;DR: It is safe to mobilize, expand, and reinfuse autologous CD34+ cells in patients with ALC and the clinical and biochemical improvement in the study group is encouraging and warrants further clinical trials.
Journal ArticleDOI
Imaging modalities for renal artery stenosis in suspected renovascular hypertension: prospective intraindividual comparison of color Doppler US, CT angiography, GD-enhanced MR angiography, and digital substraction angiography.
Christos Rountas,Marianna Vlychou,K. Vassiou,Vassilios Liakopoulos,E. Kapsalaki,Georgios Koukoulis,Ioannis V. Fezoulidis,I. Stefanidis +7 more
TL;DR: CTA and GD-enhanced MRA have comparable and satisfactory results with respect to the negative predictive accuracy of the suspected renal artery stenosis and the concept of an imaging algorithm including US as screening test when appropriate and CTA or MRA as the second step-procedure is suggested.
Journal ArticleDOI
Intradialytic aerobic exercise training ameliorates symptoms of restless legs syndrome and improves functional capacity in patients on hemodialysis: a pilot study
Giorgos K. Sakkas,Georgios M. Hadjigeorgiou,Christina Karatzaferi,Maria Maridaki,Christoforos D. Giannaki,Peter R. Mertens,Christos Rountas,Marianna Vlychou,Vassilios Liakopoulos,Ioannis Stefanidis +9 more
TL;DR: In conclusion, aerobic exercise training is safe and efficacious in reducing RLS symptoms and improving quality of life in patients with RLS on HD.
Journal ArticleDOI
Influence of the Learning Curve on Safety and Efficiency of Laparoscopic Sleeve Gastrectomy
Dimitris Zacharoulis,Eleni Sioka,Dimitris Papamargaritis,Olga Lazoura,Christos Rountas,Eleni Zachari,George Tzovaras +6 more
TL;DR: LSG can be safely and efficiently performed in a newly established bariatric center following a mentorship procedure and the operative time and hospital stay may significantly decrease with experience early in the learning curve, as opposed to mortality and morbidity rates, conversion rate, and EWL.
Journal ArticleDOI
Minimally invasive and selective hydrodynamic gene therapy of liver segments in the pig and human.
Shirin Elizabeth Khorsandi,Philippe Bachellier,J C Weber,M Greget,D. Jaeck,Dimitris Zacharoulis,Christos Rountas,S Helmy,S Helmy,A Helmy,M Al-Waracky,Hosny Salama,Long R. Jiao,Joanna Nicholls,A J Davies,Nataša Levičar,Steen Lindkaer Jensen,Nagy A. Habib +17 more
TL;DR: Based on provisional data, minimally invasive selective HGT of liver segments appears to be technically safe, but further work is required to optimize the efficiency of gene transfer in order to achieve clinical benefit.
