A better understanding of the factors that contribute to heterogeneous outcomes and lifetime disease burden in hypertrophic cardiomyopathy (HCM) is critically needed improve patient management outcomes. The Sarcomeric Human Cardiomyopathy Registry (SHaRe) was established provide scale data required address these issues, aggregating longitudinal datasets curated by eight international HCM specialty centers.

Quantification of disease severity supports the development evidence-based treatments. Assessments to capture clinical improvement in hidradenitis suppurativa (HS) can be improved.This study aimed validate Hidradenitis Suppurativa Clinical Response (HiSCR), which is defined as a ≥ 50% reduction inflammatory lesion count (sum abscesses and nodules, AN), no increase or draining fistulas HS when compared with baseline meaningful endpoint for treatment.Patients 3 ANs at Phase II adalimumab trial...

Background: The DANISH study (Danish Study to Assess the Efficacy of ICDs [Implantable Cardioverter Defibrillators] in Patients With Non-Ischemic Systolic Heart Failure on Mortality) did not demonstrate an overall effect all-cause mortality with ICD implantation. However, prespecified subgroup analysis suggested a possible age-dependent association between implantation and survival benefit seen only youngest patients. nature this relationship age outcome primary prevention patients...

Purpose: To evaluate the performance characteristics of computed tomographic (CT) urography for detection bladder cancer in patients at risk disease. Materials and Methods: Institutional review board approval was obtained this retrospective HIPAA-compliant medical records 2600 consecutive undergoing CT urography. Of these, 838 urograms 779 (449 men, mean age 62 years, range 27–92 years; 330 women, 56 18–86 years) evaluated hematuria or a history urothelial cancer, who had undergone...

Background The randomized phase 3 ELOQUENT‐2 study (NCT01239797) evaluated the efficacy and safety of elotuzumab plus lenalidomide dexamethasone (ELd) versus (Ld) in relapsed/refractory multiple myeloma (RRMM), to date, has longest follow‐up any monoclonal antibody patients with RRMM. Methods In this extended 4‐year trial, coprimary endpoints progression‐free survival (PFS) overall response rate as well secondary endpoint were assessed. absence head‐to‐head trials comparing Ld‐based triplet...

Functional variability among boys with Duchenne muscular dystrophy (DMD) is well recognised and complicates interpretation of clinical studies. We hypothesised that DMD could be clustered into groups sharing similar trajectories ambulatory function over time, as measured by the North Star Ambulatory Assessment (NSAA) total score. also explored associations other variables such age, functional abilities, genotype. Using NorthStar Clinical Network database, 395 patients >1 NSAA assessment were...

To evaluate the World Health Organization's (WHO) Bleeding Scale in two studies of eltrombopag adults with chronic immune thrombocytopenia (ITP).Validated scales assessing bleeding ITP are lacking. Data from long-term, phase 3 clinical trials (RAISE: NCT00370331; EXTEND: NCT00351468) that assessed were analyzed to performance WHO Scale.In RAISE, effect size (0.71), standardized response (0.75), and responsiveness statistics (0.57) moderate for bruising assessments.

Abstract Chimeric antigen receptor T-cell (CAR-T) therapy yields durable responses in patients with relapsed/refractory diffuse large B-cell lymphoma (r/r DLBCL). Cytokine release syndrome (CRS) is a CAR-T therapy–related adverse event. To date, clinical trials of different products have not been aligned on CRS grading scales and management algorithms. We assessed concordance between the Penn, Lee, American Society for Transplantation Cellular Therapy (ASTCT) systems by retrospectively...

High variability in patients' changes 6 minute walk distance (6MWD) over time has complicated clinical trials of treatment efficacy Duchenne muscular dystrophy (DMD). We assessed whether boys with DMD could be grouped into classes that shared similar ambulatory function trajectories as measured by 6MWD. Ambulatory aged 5 years or older genetically confirmed who were enrolled a natural history study at 11 care centers throughout Italy included. For each boy, standardized assessments 6MWD...
