Human-induced pluripotent stem cells(iPSCs)are an accessible source of adult-derived,patient-specific pluripotent stem cells for use in basic research,drug discovery,disease modeling,and stem cell *** the accessibility of methods to obtain iPSCs regardless of the cell source can enhance their clinical ***,our purpose is to report a simple protocol to obtain iPS-like cells from urine-derived renal epithelial cells(RECs)using different extracellular matrices and transfection *** this study,we began by culturing urine-derived cells from healthy donors to establish a primary culture of renal epithelial cells,followed by their ***,we generated iPS-like cells by transfecting renal epithelial cells(RECs)with vectors expressing Oct4,Sox2,L-Myc,Lin-28,and Klf4,and we compared the efficacy of different extracellular matrices and transfection *** resultant iPS-like cells showed a human embryonic stem cell-like morphology and expressed the specific pluripotency markers Oct3/4,Nanog,Lin28,and *** concluded that Lipofectamine Stem Cell transfection reagent is more effective than FuGENE in obtaining iPS-like cells under the conditions ***,the three matrices are similar in their efficiency of obtaining iPS-like *** report provides an experimental protocol for obtaining and generating iPS-like cells from urine samples for further cell therapy research on different human diseases.

Objective To assess the prognostic impact of a routine invasive strategy according to the frailty burden in patients with non-ST-segment elevation myocardial infarction(NSTEMI)from the MOSCA-FRAIL clinical *** The MOSCA-FRAIL trial randomized 167 frail patients,defined by a Clinical Frailty Scale(CFS)≥4,with NSTEMI to an invasive or conservative *** primary endpoint was the number of days alive and out of hospital(DAOH)one year after *** this subanalysis,we compared the impact of an invasive strategy on the outcomes between vulnerable(CFS=4,n=43)and frail(CFS>4,n=124)*** Compared to vulnerable patients,frail patients presented lower values of DAOH(289.8 vs.320.6,P=0.146),more read-missions(1.03 vs.0.58,P=0.046)and higher number of days spent at the hospital during the first year(10.8 vs.3.8,P=0.014).The cau-ses of readmission were mostly non-cardiac(56%).Among vulnerable patients,DAOH were similar regardless of strategy(invasive ***:325.7 vs.314.7,P=0.684).Among frailest patients,the invasive group tended to have less DAOH(267.7 vs.311.1,P=0.117).Indeed,patients with CFS>4,invasively managed lived 29 days less than their conservative *** contrast,the-re were no differences in the subgroup with CFS=*** Adult patients with frailty and NSTEMI showed different prognosis according to the degree of frailty.A routine in-vasive strategy does not improve outcomes and might be harmful to the frailest patients.
