Randomised controlled trials evaluating anticancer therapies in haematological cancers: an overview of global research activity.

Background: Design, results, and interpretation of oncology randomised controlled trials (RCTs) have changed substantially over the past decade. In this study, we describe all RCTs evaluating anticancer therapies in haematological cancers published globally during 2014-2017 with comparisons with solid tumours RCTs.

Methods: A PubMed literature search identified all phase 3 RCTs of anticancer therapy for haematological cancers and solid tumours published globally during 2014-2017.

International Analysis of Electronic Health Records of Children and Youth Hospitalized With COVID-19 Infection in 6 Countries.

Importance: Additional sources of pediatric epidemiological and clinical data are needed to efficiently study COVID-19 in children and youth and inform infection prevention and clinical treatment of pediatric patients.

Objective: To describe international hospitalization trends and key epidemiological and clinical features of children and youth with COVID-19.

Design, Setting, And Participants: This retrospective cohort study included pediatric patients hospitalized between February 2 and October 10, 2020.

A phase I study of the metal ionophore clioquinol in patients with advanced hematologic malignancies.

Unlabelled: Clioquinol is a small-molecule metal ionophore that inhibits the proteasome through a metal-dependent mechanism. Here, we report a phase I study of clioquinol in patients with refractory hematologic malignancies. Neuropathy and abdominal pain were dose-limiting toxicities.

Passive infusion of immune serum into simian immunodeficiency virus-infected rhesus macaques undergoing a rapid disease course has minimal effect on plasma viremia.

Antibody responses are often considered to play only a limited role in controlling viremia during chronic infections with human or simian immunodeficiency virus (SIV). We investigated this by determining the effect of passively infused antibody on plasma viremia in infected rhesus macaques. The emphasis of the study was to understand the mechanism(s) underlying any observed effects.

Ascorbic acid absorption in patients with systemic sclerosis.

Objective: To investigate whether reduced circulating levels of ascorbic acid in patients with systemic sclerosis (SSc) are a result of malabsorption.

Methods: Eight patients with SSc, but with no evidence of bacterial overgrowth, and 8 healthy controls were recruited. On the first day of study, each subject was given orally an aliquot of [14C] ascorbic acid, which was then "flushed out" by oral intake of unlabeled ascorbic acid for the following 7 days.
