Lipid nanoparticle-mediated intracameral mRNA delivery facilitates gene expression and editing in the anterior chamber of the eye.

Lipid nanoparticles (LNPs) have shown great potential in the field of gene therapy for retinal diseases. To expand on this application, we investigated LNP-mediated mRNA delivery to the anterior chamber of the eye via the intracameral (IC) route of administration. Here, we show that IC injections of LNPs facilitated protein expression and gene editing in the trabecular meshwork (TM).

Fitness, Body Composition, and Health Behaviors in Long-Term Survivors of Adolescent and Young Adult Cancers.

To investigate cardiorespiratory fitness (CRF), body composition, health behaviors, and health-related quality of life (HRQoL) in adolescent and young adult cancer survivors (AYA-CS) compared with age-matched counterparts without a cancer diagnosis. This cross-sectional study recruited participants aged 15-25 years at the time of their cancer diagnosis and ≥ 5 years post-treatment. Participants completed cardiopulmonary exercise testing, dual-energy X-ray absorptiometry, food diaries, physical activity (PA), fatigue, and HRQoL questionnaires.

A multi-site feasibility study of a stepped-care telehealth intervention for depression and anxiety in post-treatment cancer survivors at community cancer clinics (WF-30917CD).

Purpose: This feasibility study estimated accrual, retention, adherence, and summarized preliminary efficacy data from a stepped-care telehealth intervention for cancer survivors with moderate or severe levels of anxiety and/or depressive symptoms.

Methods: Participants were randomized to intervention or enhanced usual care (stratified by symptom severity). In the intervention group, those with moderate symptoms received a cognitive-behavioral therapy (CBT) workbook/6 bi-weekly check-in calls (low intensity) and severe symptoms received the workbook/12 weekly therapy sessions (high intensity).

Dietary Macronutrient Composition and Risk of Radiation-Induced Acute Skin Toxicity in Women with Breast Cancer: Results from the ATHENA Project.

Background: The impact of the dietary macronutrient composition and its subcomponents (saccharides, fatty acids, and protein sources) on radiation-induced acute skin toxicity (AST) in breast cancer (BC) patients is unknown. Hence, we examined the association between dietary macronutrients and their subcomponents and the risk of ≥grade 2 (G2) AST post-radiotherapy among women with BC.

Methods: An observational study was conducted among 161 BC patients treated with radiotherapy and enrolled in the ATHENA project in Italy.

Metabolic reprogramming of macrophages by PKM2 promotes IL-10 production via adenosine.

Macrophages play a crucial role in immune responses and undergo metabolic reprogramming to fulfill their functions. The tetramerization of the glycolytic enzyme pyruvate kinase M2 (PKM2) induces the production of the anti-inflammatory cytokine interleukin (IL)-10 in vivo, but the underlying mechanism remains elusive. Here, we report that PKM2 activation with the pharmacological agent TEPP-46 increases IL-10 production in LPS-activated macrophages by metabolic reprogramming, leading to the production and release of ATP from glycolysis.
