Improving outcomes for care partners of individuals with traumatic brain injury: Results for a mHealth randomized control trial of the CareQOL app.

Objective: To test the efficacy of a randomized control trial low-touch mobile health intervention designed to promote care partner self-awareness and self-care.

Design: This randomized controlled trial (RCT) included a baseline assessment of self-report surveys of health-related quality of life (HRQOL), care partner-specific outcomes, and the functional/mental status of the person with TBI, as well as a 6-month home monitoring period that included three daily questions about HRQOL, monthly assessments of 12 HRQOL domains, and the use of a Fitbit® to continuously monitor physical activity and sleep. HRQOL surveys were repeated at 3- and 6-months post-home monitoring.

Prime Editor Gene Therapy and TREX1 Mosaicism in Retinal Vasculopathy with Cerebral Leukoencephalopathy.

TREX1 mutations underlie a variety of human diseases, including retinal vasculopathy with cerebral leukoencephalopathy (RVCL or RVCL-S), a catastrophic adult-onset vasculopathy that is often confused with multiple sclerosis, systemic vasculitis, or systemic lupus erythematosus. Patients with RVCL develop brain, retinal, liver, and kidney disease around age 35-55, leading to premature death in 100% of patients expressing an autosomal dominant C-terminally truncated form of TREX1. We previously demonstrated that RVCL is characterized by high levels of DNA damage, premature cellular senescence, and risk of early-onset breast cancer before age 45.

Multi-stage-mixing to create a core-then-shell structure improves DNA-loaded lipid nanoparticles' transfection by orders of magnitude.

The unprecedented success of mRNA-lipid nanoparticles (LNPs) has highlighted their power for protein expression, but the hours-long half-life of mRNA severely limits their use in chronic diseases. In contrast, DNA LNPs display months-long expression and genetically encode cell type specificity, but their use has been hindered by poor protein expression (orders of magnitude lower than mRNA LNPs). To overcome this, we introduce multi-stage mixing (MSM) microfluidics to control the internal structure of LNPs and use it to create core-then-shell (CTS) structured DNA LNPs.

Four New Patient-Reported Outcome Measures Examining Health-Seeking Behavior in Persons With Type 2 Diabetes Mellitus (REDD-CAT): Instrument Development Study.

Background: The management of type 2 diabetes mellitus (T2DM) includes mastery of complex care activities, self-management skills, and routine health care encounters to optimize glucose control and achieve good health. Given the lifelong course of T2DM, patients are faced with navigating complex medical and disease-specific information. This health-seeking behavior is a driver of health disparities and is associated with hospitalization and readmission.
