Methods and results Patients were suitable for inclusion if they presented (i) an ACS that was successfully revascularized by manual thrombo-aspiration and (ii) a large residual thrombus on coronary angiography and initial FD-OCT analysis. These patients underwent a second procedure including FD-OCT analysis after several days of optimal antithrombotic therapy. Serial area measurements within the athero-thrombotic culprit lesion were performed to evaluate the selleckchem OCT-thrombus score, volume, and length. Sixteen patients (88% men/age = 59.3 +/-

4.1 years/94% STEMI) were included in the study. The mean delay between OCT analyses was 3.9 +/- 0.3 day. No adverse event was observed during this interval. We observed a reduction of thrombus burden between the two analyses, as assessed by the significant reductions in OCT-thrombus score (22.3 +/- 2.6 vs. 10.3 +/- 1.3, P smaller than 0.001), OCT-thrombus volume (9.6 +/- 2.3 see more vs. 3.6 +/- 0.9 mm(3), P = 0.003), and OCT-thrombus

length (11.1 +/- 1.4 vs. 7.4 +/- 0.8 mm, P = 0.01). The percentages of OCT-thrombus score and volume reduction were highly correlated with the inter-OCT analyses delay (respectively rho = 0.65 and rho = 0.84, P smaller than 0.01 for both). Conclusion FD-OCT assessment of thrombus volume in selected ACS patients is feasible, safe, and could allow clot regression monitoring in vivo.”
“Context.-Renal interstitial fibrosis and, to a lesser extent, sclerotic glomeruli correlate with poor renal function. However, not all nonfunctional glomeruli are sclerotic. Many or most glomeruli with periglomerular fibrosis, while retaining blood flow, probably do not filter; therefore, they may not contribute to renal function.\n\nObjective.-To examine the relationship of periglomerular fibrosis and the sum of globally sclerotic glomeruli and glomeruli with periglomerular fibrosis (GSG+PF) with interstitial fibrosis and renal function.\n\nDesign.-Native kidney biopsies from 177 patients with chronic

renal injury were assessed for interstitial fibrosis, glomerular sclerosis, Citarinostat inhibitor and GSG+PF. Renal biopsies with active or acute lesions were not included. The percentage of globally sclerotic glomeruli and GSG+PF was correlated with the degree of interstitial fibrosis and serum creatinine levels.\n\nResults.-The percentage of GSG+PF correlates better with the degree of interstitial fibrosis and renal function than does the percentage of globally sclerotic glomeruli alone. This appears particularly true in chronic renal diseases of patients without diabetes. The number of globally sclerotic glomeruli correlates better with interstitial fibrosis and renal function than does the sum of globally and segmentally sclerotic glomeruli.\n\nConclusions.
