Risk assessment of complex organoarsenic species in food.

The European Commission asked EFSA for a risk assessment on complex organoarsenic species in food. They are typically found in marine foods and comprise mainly arsenobetaine (AsB), arsenosugars and arsenolipids. For AsB, no reference point (RP) could be derived because of insufficient toxicity data.

Multigene Copy Number Alteration Risk Score Biomarker-Based Enrichment Study Designs in Metastatic Castrate-Resistant Prostate Cancer.

Purpose: A composite multigene risk score derived from tumor-biology alterations specific to metastatic castrate-resistant prostate cancer (mCRPC) state was evaluated as a classifier to design biomarker-based enrichment clinical trials.

Methods: A plasma cell-free DNA copy number alteration risk score based on alterations in 24 genes was simulated to develop a biomarker classifier-based clinical trial design enriched for high-risk patients to detect a survival advantage of a novel treatment (hazard ratio of 0.70 with 80% power).

Augmenting Prognostication: Utilizing Activity Trackers to Enhance Survival Prediction in Metastatic Non-Small Cell Lung Cancer.

Introduction/background: Prognostication by performance status (PS) assessment is a fundamental element of treatment decisions and clinical trial design in oncology, but it is limited by subjectivity and potential miscommunication between patient, physician, and family. Activity tracker offers the potential to collect a broad range of patient-generated data to supplement the assessment of PS.

Patients And Methods: Patients with metastatic NSCLC (mNSCLC) participated in a single institute, prospective, observational feasibility study conducted at Huntsman Cancer Institute.

Reducing UVR Exposure in Pregnant Women and Infants: A Pilot Study.

Sun protection during pregnancy is critical for both maternal and infant skin cancer prevention, yet gaps remain in addressing this behavior in pre and postnatal settings. This pilot study aimed to evaluate the feasibility and acceptability of a peer-led intervention for expectant mothers' sun protection behaviors for themselves and their newborns and examine the preliminary effects on mothers' skin cancer knowledge, attitudes, and sun protection behaviors for themselves and their infants. Expectant mothers were recruited from medical clinics and community settings and were asked to complete surveys and interviews.
