Recruitment planning is needed to establish a foundation for obesity prevention research with high risk, disadvantaged perinatal adolescent populations. In the context of developing clinical trial protocols, investigators partnered with Mississippi's Nutrition Program for Women, Infants and Children (WIC) and adopted the Clinical Trials Transformative Initiative (CTTI) framework for recruitment planning to identify and mitigate challenges to recruitment early in the clinical trial development process. The recruitment protocol consisted of 20 passive strategies grounded in principles of partner and community engagement and was flexible, accommodating, altruistic, community-focused, and minimally burdensome to partners and participants. The recruitment goal included 150 adolescent-coparticipant dyads and 145 dyads (96.7%) were successfully recruited. Investigators demonstrated the feasibility of recruiting a disadvantaged and vulnerable perinatal adolescent population that is underrepresented in health research, in one of the most persistently impoverished and poor health regions in the U.S. Four important aspects of recruitment planning using the CTTI framework are discussed including (1) establishing partnerships with trusted community resources is a paramount investment; (2) dedicating time and resources to know and go to your community is invaluable; (3) fostering trust by offering convenient, continuous and clear communication; and (4) encouraging collaboration and participation through limiting partner and participant burden. Establishing organizational and community partnership requires a substantial amount of invaluable time and fosters recruitment success. Following the CTTI recommendations for recruitment planning led to a robust recruitment protocol that will be used in future intervention trials with an understudied perinatal adolescent population with high risk for poor maternal and fetal health outcomes.
Pragmatic and comparative effectiveness randomized controlled trials (RCTs) aim to be highly generalizable studies, with broad applicability and flexibility in methods. These trials also address recruitment issues by minimizing exclusions. The trials may also appeal to potential subjects because of lower risk and lower burdens of participation. We sought to examine rates of refusal and uses of waivers of informed consent in pragmatic and comparative effectiveness RCTs.

A systematic review of pragmatic and comparative effectiveness RCTs performed wholely or in part in the United States and first published in 2014 and 2017.

103 studies involving 105 discrete populations were included for review. Refusal data was collected for 71 RCTs. Pinometostat Histone Methyltransferase inhibitor Overall, studies reported an average rate of 31.9% of potential subjects refused participation; on an individual basis, 38.4% of people asked to take part refused at some point during recruitment. 23 trials (22%) were performed, at least in part, with a waiver of informed consent, 7 (30%) of which provided any form of notice to subjects.

Overall refusal rates for pragmatic and comparative effectiveness RCTs appear roughly the same as other types of research, with studies reporting about a third of people solicited for participation refuse. Moreover, informed consent was waived in 22% (95% Binomial exact Confidence Interval 13.9-30.5%) of the trials, and further study is needed to understand when waivers are justified and when notice should be provided.

However, the availability and assessment of physical activity programs that are safe and appropriate for homebound older adults at risk for nursing home admission are limited. Here we describe the protocol for a randomized controlled trial that examines the effectiveness of a gentle physical activity program. Delivered by home care aides who regularly help hard-to-reach older home care clients with housekeeping and routine personal care services in the home, this program is implemented in a real-world context of caregiver-client dyads in a Medicaid-funded home care program. The trial uses a two-group repeated measures design (baseline, Month 4, and Month 8) with 300 pairs of eligible home care clients and their home care aides. The results from this trial could provide evidence and guidelines for a new model of home care, which would facilitate the working together of older home care clients and their home care aides to maintain or improve the functional status of nursing home-eligible older adults.The SAGA (Spt-Ada-Gcn5 acetyltransferase) complex is an evolutionarily conserved histone acetyltransferase complex that has a critical role in histone acetylation, gene expression, and various developmental processes in eukaryotes. However, little is known about the composition and function of the SAGA complex in plants. In this study, we found that the SAGA complex in Arabidopsis thaliana contains not only conserved subunits but also four plant-specific subunits three functionally redundant paralogs, SCS1, SCS2A, and SCS2B (SCS1/2A/2B), and a TAF-like subunit, TAFL. Mutations in SCS1/2A/2B lead to defective phenotypes similar to those caused by mutations in the genes encoding conserved SAGA subunits HAG1 and ADA2B, including delayed juvenile-to-adult phase transition, late flowering, and increased trichome density. Furthermore, we demonstrated that SCS1/2A/2B are required for the function of the SAGA complex in histone acetylation, thereby promoting the transcription of development-related genes. These results together suggest that SCS1/2A/2B are core subunits of the SAGA complex in Arabidopsis. Compared with SAGA complexes in other eukaryotes, the SAGA complexes in plants have evolved unique features that are necessary for normal growth and development.
