BACKGROUND Prior studies of cardiac contractility modulation (CCM) employed a 3-lead Optimizer system. A new 2-lead system eliminated the need for an atrial lead. This study tested the safety and effectiveness of this 2-lead system compared with the 3-lead system. METHODS Patients with New York Heart Association III/IVa symptoms despite medical therapy, left ventricular ejection fraction 25% to 45%, and not eligible for cardiac resynchronization therapy could participate. All subjects received an Optimizer 2-lead implant. The primary end point was the estimated difference in the change of peak VO2 from baseline to 24 weeks between FIX-HF-5C2 (2-lead system) subjects relative to control subjects from the prior FIX-HF-5C (3-lead system) study. Changes in New York Heart Association were a secondary end point. The primary safety end point was a comparison of device-related adverse events between FIX-HF-5C2 and FIX-HF-5C subjects. RESULTS Sixty subjects, 88% male, 66±9 years old with left ventricular ejection frac. Device-related adverse effects are less with the 2-lead system.

METHODS We performed a prospective, single-arm, multicenter, US Food and Drug Administration-approved feasibility trial of iVAS therapy as a bridge to transplant or decision following the FIH (First-In-Human) trial. RESULTS Forty-seven patients were enrolled, and 45 patients (median 61 years old, 37 males, and 30 listed on United Network of Organ Sharing) received iVAS support for median 44 (25-87) days. There were no intraoperative complications. Success was defined as survival or transplant on iVAS therapy free from disabling stroke. Outcome success at 30 days (the primary end point of this study) and at 6 months was 89% and 80%, respectively. During 6 months of iVAS support, 2 patients died and 2 patients experienced disabling neurological dysfunction. Six-minute walk distance, 2-minute step test, and Kansas City Cardiomyopathy Questionnaire score improved during 4-week iVAS support. CONCLUSIONS This feasibility trial demonstrated promising short-term outcomes of iVAS therapy with improved functional capacity and quality of life during the therapy.

They identify considerable replicability issues, concluding that "current 'state-of-the-art' methods in the psychopathology network literature […] are not well-suited to analyzing the structure of the relationships between individual symptoms". Such strong claims require strong evidence, which the authors do not provide. https://www.selleckchem.com/products/sbc-115076.html FWMK identify low replicability by analyzing point estimates of networks; contrast low replicability with results of two statistical tests that indicate higher replicability, and conclude that these tests are problematic. We make four points. First, statistical tests are superior to the visual inspection of point estimates, because tests take into account sampling variability. Second, FWMK misinterpret the statistical tests in several important ways. Third, FWMK did not follow established recommendations when estimating networks in their first study, underestimating replicability. Fourth, FWMK draw conclusions about methodology, which does not follow from investigations of data, and requires investigations of methodology. Overall, we show that the "poor replicability "observed by FWMK occurs due to sampling variability and use of suboptimal methods. We conclude by discussing important recent simulation work that guides researchers to use models appropriate for their data, such as nonregularized estimation routines.PURPOSE The aims of this study were to compare the biometric parameters and axial lengths of eyes with phacomorphic glaucoma and mature cataract and to identify differences that might predispose to development of phacomorphic glaucoma. METHODS Three hundred forty-two patients were enrolled in this retrospective study. The eyes were divided into four groups-Group (G)1 phacomorphic glaucoma (n = 29), G2 mature cataract (n = 313), G3 contralateral phacomorphic glaucoma (n = 29), and G4 contralateral mature cataract (n = 313). Central corneal thickness and anterior chamber depth were assessed by optical low-coherence reflectometry (Lenstar LS 900®; Haag-Streit AG, Switzerland), while axial length was determined by A-scan ultrasound biometry. RESULTS The mean central corneal thickness of G1 was significantly higher than in other groups (p  less then  0.001) and the mean anterior chamber depth of G1 was the lowest among the groups (p  less then  0.001). Also, G2 had lower mean anterior chamber depth than G4 (p  less then  0.001) and G3 had lower mean anterior chamber depth than G4 (p = 0.007). Anterior chamber depth less than 3.27 mm had the higher odds ratio for distinguishing G3 versus G4 (odds ratio = 10.79, p  less then  0.001). Furthermore, patients aged ⩾68.9 years had the higher odds ratio for distinguishing G1 versus G2 (odds ratio = 2.82, p = 0.019). There was no significant difference in the presence of pseudoexfoliation material between G1 and G2 (p = 0.057). There were no significant differences in axial length values among the four groups (p = 0.097). CONCLUSION Advanced age and shallow anterior chamber depth were found to be risk factors for developing phacomorphic glaucoma, but the presence of pseudoexfoliation material was not found to play a role as a risk factor in phacomorphic glaucoma development.Adenosquamous carcinoma of the head and neck is a rare cancer associated with poor prognosis. Histologically, it is identified through the presence of both adenocarcinoma and squamous cell carcinoma, although it may be difficult to diagnose from initial endoscopic biopsies. We report a case of adenosquamous carcinoma of the glottis in an 82-year-old female patient who presented with progressive hoarseness of voice and in whom initial biopsies had shown only moderate to severe dysplasia. This is the first case in the literature of a primary adenosquamous carcinoma of the glottis managed successfully with a CO2 laser left type Va cordectomy. The patient remained disease-free 28 months postoperatively.
