A randomized, placebo-controlled, cross-over trial of ketamine in Rett syndrome.

Background: Preclinical studies and anecdotal case reports support the potential therapeutic benefit of low-dose oral ketamine as a treatment of clinical symptoms in Rett syndrome (RTT); however, no controlled studies have been conducted in RTT to evaluate safety, tolerability and efficacy.

Design: This was a sequentially initiated, dose-escalating cohort, placebo-controlled, double blind, randomized sequence, cross-over study of oral ketamine in 6-12-year-old girls with RTT to evaluate short-term safety and tolerability and explore efficacy.

Methods: Participants were randomized to either five days treatment with oral ketamine or matched placebo, followed by a nine-day wash-out period and then crossed-over to the opposite treatment.

Effects of a Distributed Form of Constraint-Induced Movement Therapy for Clinical Application: The Keys Treatment Protocol.

Background/aim: Currently, there are limited evidence-based protocols for improving upper extremity (UE) motor function after stroke. The Keys protocol, a distributed form of constraint-induced movement therapy (CIMT), delivers CIMT components in fewer hours per day over an extended period, fitting outpatient rehabilitation schedules and third-party payor models. This pilot study aimed to assess the effectiveness of the Keys protocol in enhancing UE capacity and performance poststroke.

Leveraging Quality Improvement Tools to Improve Administration of First-line Surgical Antibiotic Prophylaxis in Patients Labeled as Penicillin Allergic.

Introduction: A reported penicillin allergy reduces the likelihood that the patient will receive first-line surgical antibiotic prophylaxis (SAP), which can increase the risk of developing a surgical site infection (SSI). This project aimed to increase the use of first-line SAP agents in orthopedic and pediatric surgery patients with a reported penicillin allergy.

Methods: The Institute for Healthcare Improvement quality improvement methodology was followed.

Genomics yields biological and phenotypic insights into bipolar disorder.

Bipolar disorder is a leading contributor to the global burden of disease. Despite high heritability (60-80%), the majority of the underlying genetic determinants remain unknown. We analysed data from participants of European, East Asian, African American and Latino ancestries (n = 158,036 cases with bipolar disorder, 2.
