Cladribine provides immunomodulation through selective targeting of lymphocyte subtypes. We report the results a 96-week phase 3 trial short-course oral tablet therapy in patients with relapsing-remitting multiple sclerosis.We randomly assigned 1326 an approximate 1:1:1 ratio to receive one two cumulative doses cladribine tablets (either 3.5 mg or 5.25 per kilogram body weight) matching placebo, given four short courses for first 48 weeks, then starting at week and 52 (for total 8 20 days...

Objective To evaluate the efficacy and safety of atacicept, an antagonist B lymphocyte stimulator/ APRIL –mediated cell activation, in patients with systemic lupus erythematosus ( SLE ). Methods ADDRESS II is a 24‐week, multicenter, randomized, double‐blind, placebo‐controlled, parallel‐arm, phase b study evaluating atacicept (ClinicalTrials.gov identifier NCT 01972568). Patients active, autoantibody‐positive receiving standard therapy were randomized (1:1:1) to receive (75 mg or 150 mg)...

Measuring the health related quality of life patients with prostate cancer in routine clinical practice is hindered by lack instruments enabling efficient, real-time, point care scoring multiple domains. Thus, we developed an instrument for this purpose.The Expanded Prostate Cancer Index Composite Clinical Practice a 1-page, 16-item questionnaire that constructed to measure urinary incontinence, irritation, and bowel, sexual hormonal We eliminated conceptually overlapping items from 3-page...

Over 70% of Canadian carpal tunnel syndrome (CTS) operations are performed outside the main operating room (OR) with field sterility and surgeon-administered pure local anesthesia [LeBlanc et al., Hand 2(4):173-8, 14]. Is OR necessary to avoid infection for this operation? This study evaluates rate in release (CTR) using minor procedure sterility.This is a multicenter prospective reporting CTR setting sterility. Field means prepping hand iodine or chlorhexidine, equivalent single drape,...

Patients with locally advanced prostate cancer have an increased risk of recurrence and mortality. In this phase II trial, we evaluate neoadjuvant enzalutamide leuprolide (EL) or without abiraterone prednisone (ELAP) before radical prostatectomy (RP) in men cancer.Eligible patients had a biopsy Gleason score 4 + 3 = 7 greater, prostate-specific antigen (PSA) greater than 20 ng/mL, T3 disease (by magnetic resonance imaging). Lymph nodes were required to be smaller mm. randomly assigned 2:1...

Despite decreased screening-based detection of clinically insignificant tumors, most diagnosed prostate cancers are still indolent, indicating a need for better strategies significant disease before treatment. We hypothesized that patients with detectable circulating tumor DNA (ctDNA) were more likely to harbor aggressive disease.

When using free fat autologous grafts as a filling material was first proposed in 1893 by Neuber,1 the idea rapidly gained enthusiasm and endorsements. Our early experience with transplantation disappointing,2 but even then it clear that could be transferred partial success. Since then, further clinical works Guerrerosantos,3 Coleman,4,5 others6-10 have shown is possible, careful handling of transplanted fat, to improve survival this tissue. We reviewed our recent experiences found several...
