TL;DR: This study did not demonstrate improved efficacy for DD temozolomide for newly diagnosed GBM, regardless of methylation status, but it did confirm the prognostic significance of MGMT methylation.
Abstract: Purpose Radiotherapy with concomitant and adjuvant temozolomide is the standard of care for newly diagnosed glioblastoma (GBM) O 6 -methylguanine-DNA methyltransferase (MGMT) methylation status may be an important determinant of treatment response Dose-dense (DD) temozolomide results in prolonged depletion of MGMT in blood mononuclear cells and possibly in tumor This trial tested whether DD temozolomide improves overall survival (OS) or progression-free survival (PFS) in patients with newly diagnosed GBM Patients and Methods This phase III trial enrolled patients older than age 18 years with a Karnofsky performance score of 60 with adequate tissue Stratification included clinical factors and tumor MGMT methylation status Patients were randomly assigned to standard temozolomide (arm 1) or DD temozolomide (arm 2) for 6 to 12 cycles The primary end point was OS Secondary analyses evaluated the impact of MGMT status

TL;DR: The abnormal interventricular septal motion in LBBB corresponded to periods of asynchrony in contraction, ejection, end systole, and end diastole between right and left ventricles.
Abstract: Eighteen patients with isolated left bundle branch block (LBBB) were compared with 10 normal control subjects. Apexcardiograms, phonocardiograms, electrocardiograms, two-dimensional and dual M-mode echocardiograms, and radionuclide ventriculograms (RNV) were performed. There were no differences in the timing of right ventricular events between LBBB and normal subjects; however, striking delays in left ventricular systolic and diastolic events were apparent in the LBBB group. The delay was associated with shortening of left ventricular diastole and resultant increase in the ratio of right to left ventricular diastolic time in LBBB (1.2 +/- 0.08) compared with normal (1.0 +/- 0.06), p less than 0.0001. First heart sound (S1) amplitude, expressed as the ratio S1/S2, was decreased in LBBB compared with normal (0.67 +/- 0.2 compared with 1.34 +/- 0.25, p less than 0.01), in part due to wide separation of the valvular contributors to S1. The abnormal interventricular septal motion in LBBB corresponded to periods of asynchrony in contraction, ejection, end systole, and end diastole between right and left ventricles. Radionuclide ventriculograms revealed decreased regional ejection fraction of the septum in LBBB (40 +/- 16%) compared with 67 +/- 7% in normal subjects (p less than 0.001), while the apical and lateral regional ejection fractions were similar in the two groups. This loss of septal contribution resulted in a reduction in global ejection fraction in LBBB compared to normals (54 +/- 7% compared with 62 +/- 5%, p less than 0.005).(ABSTRACT TRUNCATED AT 250 WORDS)

TL;DR: A method first introduced by Stolzenberg (1980) for estimating indirect effects in models of mediators and outcomes that are nonlinear functions but linear in their parameters is described and extended.
Abstract: Most treatments of indirect effects and mediation in the statistical methods literature and the corresponding methods used by behavioral scientists have assumed linear relationships between variables in the causal system. Here we describe and extend a method first introduced by Stolzenberg (1980) for estimating indirect effects in models of mediators and outcomes that are nonlinear functions but linear in their parameters. We introduce the concept of the instantaneous indirect effect of X on Y through M and illustrate its computation and describe a bootstrapping procedure for inference. Mplus code as well as SPSS and SAS macros are provided to facilitate the adoption of this approach and ease the computational burden on the researcher.

TL;DR: A model for power measurement and the results of a first attempt to empirically measure power relationships within a specific channel of distribution are presented.
Abstract: The measurement of power is a prerequisite for the analysis of the distribution channel as a behavioral system. This article presents a model for power measurement and the results of a first attemp...

TL;DR: In this paper, a factor analytic investigation of the interpersonal attraction construct was conducted and the results indicated that the resulting 15-item instrument can be expected to measure reliably three dimensions of interpersonal attraction.
Abstract: The study reports a factor analytic investigation of the interpersonal attraction construct. Two‐hundred and fifteen subjects completed 30 Likert‐type, seven‐step scales concerning an acquaintance. Factor analysis indicated three dimensions of the interpersonal attraction construct which were labeled “task” “social” and “physical.” The results of this study and four replications suggest that the resulting 15‐item instrument can be expected to measure reliably three dimensions of interpersonal attraction.
