Global DNA methylomes reveal oncogenic-associated 5-hydroxylmethylated cytosine (5hmC) signatures in the cell-free DNA of cancer patients.

Characterization of tumor epigenetic aberrations is integral to understanding the mechanisms of tumorigenesis and provide diagnostic, prognostic, and predictive information of high clinical relevance. Among the different tumor-associated epigenetic signatures, 5 methyl-cytosine (5mC) and 5-hydroxymethylcytosine (5hmC) are the two most well-characterized DNA methylation alterations linked to cancer pathogenesis. 5hmC has a tissue-specific distribution and its abundance is subjected to changes in tumor DNA, making it a promising biomarker.

Treatment with a superoxide dismutase mimetic for joint preservation during 35 and 75 days in orbit aboard the international space station, and after 120 days recovery on Earth.

Reduced weight-bearing during spaceflight has been associated with musculoskeletal degradation that risks astronaut health and performance in transit and upon reaching deep space destinations. Previous rodent experiments aboard the international space station (ISS) have identified that the spaceflight-induced molecular arthritic phenotype was characterized with an increase in oxidative stress. This study evaluated if treatment with a superoxide dismutase (SOD) mimetic on orbit could prevent spaceflight-induced damage to the knee and hip articular cartilage, and the menisci in rodents.

Prevalence of Autoimmune Diseases in Patients Treated With Immune Checkpoint Inhibitors: An Epidemiological Study Using A Global Network of Health Care Organizations.

Objective: Evaluate prevalence of new onset autoimmune conditions (ACs) after commencement of immune checkpoint inhibitors (ICIs).

Methods: This retrospective observational study was done using TriNetX. Patients with neoplasm for which ICIs were approved were stratified into two groups based on ICI use.

Determinants of stigma against help-seeking in schools and help-seeking behaviors of Asian American and Latinx youth experiencing internalizing problems.

Objectives: This study examined individual and school factors related to stigma against seeking mental health support among Asian American and Latinx youth and tested whether stigma moderated the link between internalizing symptoms and help-seeking behaviors across different sources of support.

Methods: Data were drawn from a cross-sectional, routine school-based mental health needs assessment. The sample included 1,371 Asian American and 801 Latinx students in Grades 4-12 ( = 8.

Effectiveness of Multilevel Implementation Strategies for Autism Interventions: Outcomes of Two Linked Implementation Trials.

Objective: This study tests the effectiveness of leader and provider-level implementation strategies to implement evidence-based interventions (EBIs) in two of the service systems caring for autistic children. The TEAMS Leadership Institute (TLI) targets implementation leadership and climate, and TEAMS Individualized Provider Strategy (TIPS) targets provider motivation and engagement.

Method: A cluster randomized hybrid type 3 implementation-effectiveness trial tested the effects of the implementations strategies when paired with AIM HI (An Individualized Mental Health Intervention for Autism) in mental health programs (Study 1) and CPRT (Classroom Pivotal Response Teaching) in classrooms (Study 2).
