RESUMO
Black men are disproportionately affected by type 2 diabetes (T2D) and experience higher diabetes-related complications than non-Hispanic White men. To address the complex barriers in diabetes self-management for Black men, we implemented a 3-month peer-led and empowerment-based Diabetes Self-Management Education (DSME) and Support (DSMS) intervention in Metro Detroit. Twenty-five Black men ≥55 years of age with self-reported T2D were randomized to the intervention group (n=12)-10 hr of DSME and 9 hr of DSMS-or enhanced usual care (EUC) group (n=13)-10 hr of DSME. Peer leaders (n = 3) were trained by certified diabetes care and education specialists (CDCESs) to cofacilitate the support sessions. Outcomes (hemoglobin A1c [HbA1c], diabetes self-care activities, and diabetes distress) were assessed preintervention and postintervention. In the intervention and EUC groups, mean HbA1c decreased by 0.20% (p = .52, SD = 0.99) and 0.13% (p = .68), respectively. General diet (p = .03, M change: 1.32, SD = 1.71) and blood glucose monitoring (p < .05, M change: 0.50, SD = 0.74) scores improved among those in the intervention group. General diet scores also improved in the EUC group: mean change: 1.77, p = .08, although changes were not statistically significant. Changes in diabetes distress scores differed based on the number of sessions attended, with a significant decrease in those attending 7 to 12 sessions (n = 7), >50%, (p = .003, M change: -5.71, SD = 3.20). Implementing a peer-led DSMS program for Black men was feasible, adopted, and led to positive changes in outcomes. Scaling up the intervention and assessing sustainability is warranted.

In multicellular organisms, sexed gonads have evolved that facilitate release of sperm versus eggs, and bilaterian animals purposefully combine their gametes via mating behaviors. Distinct neural circuits have evolved that control these physically different mating events for animals producing eggs from ovaries versus sperm from testis. In this review, we will describe the developmental mechanisms that sexually differentiate neural circuits across three major clades of bilaterian animals-Ecdysozoa, Deuterosomia, and Lophotrochozoa. While many of the mechanisms inducing somatic and neuronal sex differentiation across these diverse organisms are clade-specific rather than evolutionarily conserved, we develop a common framework for considering the developmental logic of these events and the types of neuronal differences that produce sex-differentiated behaviors.

Previous literature has indicated that Black men are twice as likely to develop type 2 diabetes compared to their non-Hispanic White counterparts and are also more likely to have associated complications. Furthermore, Black men have lower access to quality health care, and masculinity norms have been shown to hinder them from seeking the limited care that is available. In this study, we aim to investigate the effect of peer-led diabetes self-management education and long-term ongoing support on glycemic management. The first phase of our study will consist of modification of existing diabetes education content to be more appropriate for the population of interest, Then, in the second phase, we will conduct a randomized controlled trial to test the intervention. Participants randomized to the intervention arm will receive diabetes self-management education, structured diabetes self-management support, and a more flexible ongoing support period. Participants randomized to the control arm will receive diabetes self-management education. Diabetes self-management education will be taught by certified diabetes care and education specialists, while the diabetes self-management support and ongoing support period will be facilitated by fellow Black men with diabetes who will be trained in group facilitation, patient-provider communication strategies, and empowerment techniques. The third phase of this study will consist of post-intervention interviews and dissemination of findings to the academic community. The primary goal of our study is to determine whether long-term peer-led support groups in conjunction with diabetes self-management education are a promising solution to improve self-management behaviors and decrease A1C levels. We will also evaluate the retention of participants throughout the study, which has historically been an issue in clinical studies focused on the Black male population. Finally, the results from this trial will determine whether we can proceed to a fully-powered R01 trial or if other modifications of the intervention are necessary.
