This was the first CHMI study of a novel antimalarial compound to compare direct venous inoculation of sporozoites and mosquito bites. Times to qRT-PCR positivity and treatment were comparable for both routes. DSM265 given 3 or 7 days before CHMI was safe and well tolerated but sterilely protected only one third of participants.
Controlled human malaria infection (CHMI) studies deliberately infect healthy participants with malaria to test interventions faster and more efficiently. Some argue the study design and high payments offered raise ethical concerns about participants' understanding of risks and undue inducement. We conducted baseline and exit interviews with 16 CHMI study participants to explore these concerns. Participants described themes including decision-making tension with friends and family, mixed motivations for participating, low study risks but high burdens, fair compensation, sacrificing values, deceiving researchers, and perceived benefits. Our findings do not support concerns that high payments limit understanding of study risks, but suggest participants may lack appreciation of study burdens, withhold information or engage in deception, and experience conflict with others regarding study participation.
IMPORTANCE Pediatric palliative care treats patients with a wide variety of advanced illness conditions, often with substantial levels of pain and other symptoms. Clinical and research advancements regarding symptom management for these patients are hampered by the scarcity of data on symptoms as well as an overreliance on clinician report. OBJECTIVE To provide a detailed description of the symptoms among patients receiving pediatric palliative care based on parental report via a validated, structured symptom assessment measure. DESIGN, SETTING, AND PARTICIPANTS Baseline data for this cross-sectional analysis were collected between April 10, 2017, and February 5, 2020, from pediatric palliative care programs in 7 children's hospitals located in Akron
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
