Evaluating Effects of Virtual Diabetes Group Visits in Community Health Centers During the COVID-19 Pandemic.

Diabetes is the seventh leading cause of death in the US. Diabetes group visits (GVs), which include group education and individual medical visits have been shown to improve clinical outcomes. However, few studies have evaluated virtual GVs. We conducted a single-arm pilot study to test the impact of virtual diabetes GVs in Midwestern community health centers (CHCs). Adult patients with diabetes participated in monthly virtual GVs for 6 months. Surveys and chart abstraction were used to assess patient-reported and clinical outcomes. Five CHCs implemented virtual GVs with 34 patients attending at least one session. Virtual GVs show promise as evidenced by these findings: (1) Patients had a nonsignificant decrease in A1C. (2) In the subgroup of patients with baseline A1C ≥ 9%, there was a significant decrease in A1C. (3) Patients had significant increases in diabetes knowledge and support as well as a decrease in diabetes distress. Future studies with a larger sample size and a control comparison group are needed to assess the impact of virtual GVs on patient outcomes.

Adapting in-person diabetes group visits to a virtual setting across federally qualified health centers.

Diabetes group visits (GVs) have been shown to improve glycemic control, enrich patient self-care, and decrease healthcare utilization among patients with type 2 diabetes mellitus (T2DM). While telehealth has become routine, virtual GVs remain understudied, especially in federally qualified health centers (FQHCs). We conducted a 5-year cluster randomized trial with a waitlist control group to test the impact of diabetes GVs on patients' outcomes in Midwestern FQHCs. Due to COVID-19, the 6 waitlisted FQHCs adapted to virtual GVs. FQHC staff were provided training and support to implement virtual GVs. The GV intervention included 6 monthly 1-1.5-h long education sessions and appointments with a primary care provider. We measured staff perspectives and satisfaction via GV session logs, monthly webinars, and staff surveys and interviews. Adaptations for implementation of virtual GV included: additional staff training, video conferencing platform use, decreased session length and group size, and adjusting study materials, activities, and provider appointments. Sites enrolled a total of 48 adults with T2DM for virtual GVs. Most FQHCs were urban and all FQHCs predominantly had patients on public insurance. Patients attended 2.1 ± 2.2 GVs across sites on average. Thirty-four patients (71%) attended one or more virtual GVs. The average GV lasted 79.4 min. Barriers to virtual GVs included patient technology issues and access, patient recruitment and enrollment, and limited staff availability. Virtual GV facilitators included providing tablets, internet access from the clinic, and technical support. Staff reported spending on average 4.9 h/week planning and implementing GVs (SD = 5.9). On average, 6 staff from each FQHC participated in GV training and 1.2 staff reported past GV experience. All staff had worked at least 1 year at their FQHC and most reported multiple years of experience caring for patients with T2DM. Staff-perceived virtual GV benefits included: empowered patients to manage their diabetes, provided patients with social support and frequent contact with providers, improved relationships with patients, increased team collaboration, and better patient engagement and care-coordination. Future studies and health centers can incorporate these findings to implement virtual diabetes GVs and promote accessible diabetes care.

Crystal Structure of the Double Homeodomain of DUX4 in Complex with DNA.

Double homeobox (DUX) transcription factors are unique to eutherian mammals. DUX4 regulates expression of repetitive elements during early embryogenesis, but misexpression of DUX4 causes facioscapulohumeral muscular dystrophy (FSHD) and translocations overexpressing the DUX4 double homeodomain cause B cell leukemia. Here, we report the crystal structure of the tandem homeodomains of DUX4 bound to DNA. The homeodomains bind DNA in a head-to-head fashion, with the linker making anchoring DNA minor-groove interactions and unique protein contacts. Remarkably, despite being tandem duplicates, the DUX4 homeodomains recognize different core sequences. This results from an arginine-to-glutamate mutation, unique to primates, causing alternative positioning of a key arginine side chain in the recognition helix. Mutational studies demonstrate that this primate-specific change is responsible for the divergence in sequence recognition that likely drove coevolution of embryonically regulated repeats in primates. Our work provides a framework for understanding the endogenous function of DUX4 and its role in FSHD and cancer.

Maturation of the immune system of the male house cricket, Acheta domesticus.

The immune system functions to counteract the wide range of pathogens an insect may encounter during its lifespan, ultimately maintaining fitness and increasing the likelihood of survival to reproductive maturity. In this study, we describe the maturation of the innate immune system of the male house cricket Acheta domesticus during the last two nymphal stages, and during early and late adulthood. Total hemolymph phenoloxidase enzyme activity, lysozyme-like enzyme activity, the number of circulating hemocytes, and encapsulation ability were all determined for each developmental stage or age examined. The number of circulating hemocytes and lysozyme-like enzyme activity were similar for all developmental stages examined. Nymphs and newly molted adult males, however, had significantly lower total phenoloxidase activity than later adult stages, yet nymphs were able to encapsulate a nylon thread just as well as adults. Encapsulation ability would thus appear to be independent of total phenoloxidase activity.
