Background: Breast cancer is the most frequent type of cancer and the second leading cause of cancer-related mortality in women. Mastectomies remain a key component of the treatment of non-metastatic breast cancer, and strategies to treat acute postoperative pain, a complication affecting nearly all patients undergoing surgery, continues to be an important clinical challenge. This study aimed to determine the impact of intraoperative methadone administration compared to conventional short-acting opioids on pain-related perioperative outcomes in women undergoing a mastectomy.

However, it is unknown to what degree Veggie Meter-assessed skin carotenoid score change is responsive to changes in carotenoid intake.
Objectives: This study aimed to evaluate Veggie Meter-assessed skin carotenoid score response in a 6-wk randomized controlled trial of a carotenoid-containing juice to determine whether the Veggie Meter can be used to detect nutritionally relevant changes in carotenoid intake; and to compare skin and plasma carotenoid responses with the 6-wk trial.
Article Synopsis
- The study investigates the feasibility, reliability, and correlation of skin carotenoid score (SCS) measurements in 4-month-old infants as a means of assessing carotenoid intake and plasma concentrations.
- Using a portable reflection spectroscopy device, researchers measured SCS in 21 infants, analyzing relationships between SCS, dietary intake, and plasma carotenoid levels, while also exploring measurements in older infants.
- Results showed strong reliability in SCS measurements and notable correlations between SCS and carotenoid intake and plasma levels, particularly in infants at 4 and 8 months old, but not in those transitioning to complementary feeding at 6 months.
Context: Dietary carotenoid intake is associated with vitamin A status and healthy visual and cognitive function in early life. To date, however, only limited population-level data on the concentrations of carotenoids in human milk or infant blood have been available to assess the dietary exposure of infants to carotenoids.
Objective: This systematic review seeks to define worldwide carotenoid concentrations in human milk and infant blood.
Introduction: The objective of this study was to develop and validate a questionnaire to better understand barriers and facilitators to physical activity among low-income, Hispanic youth.
Methods: Low-income Hispanic middle and high school students were recruited to participate in this study from a public charter school district in Houston, TX. Questionnaire development and psychometric validation included scale development and question pretesting, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), construct validity, and test-retest reliability of the scales.
