Doxorubicin is a highly effective chemotherapeutic agent for treating several types of cancer; however, it can induce cardiotoxicity. We evaluated the influence of Pera and Moro orange juices on cardiac remodeling induced by acute administration of doxorubicin in rats. ⋯ Pera and Moro orange juices attenuated cardiac remodeling induced by doxorubicin, improved myocardial energy metabolism, and attenuated oxidative stress. However, Moro orange juice was more effective than Pera orange juice in modifying energy metabolism.

Malnutrition is a frequent comorbidity in people with cancer, associated with poor tolerance of anticancer treatments, prognosis, and quality of life. Despite the abundance of scientific literature supporting this evidence and the availability of international guidelines for managing nutritional care in people with cancer, attitudes about this issue still vary considerably among oncologists, to the point that many patients who are malnourished do not receive adequate nutritional support. ⋯ In 2019, the Italian Society of Oncological Surgery and the Technical Scientific Association of Food, Nutrition and Dietetics joined the working group. In this article, we present the updated initiatives and the perspectives of this intersociety project.

We sought to develop and evaluate the relative validity of a dietary diversity questionnaire (DDQ) that reflects food-group diversity, food variety, and micronutrient adequacy among New Zealand women. ⋯ The DDQ is a quick, low-burden tool for describing nutritious and discretionary dietary diversity reflecting micronutrient adequacy in high-income settings. It requires further validation across different time frames, population groups, and settings.

There are several isomers of carotene, the main ones being alpha and beta carotene (i.e., α-carotene and β-carotene). The latter serves as a precursor for vitamin A, and is thus a well-studied carotenoid in health, food, and nutrition research. ⋯ A search on PubMed, Elsevier's sciencedirect.com, and Springer Nature's SpringerLink platforms reveals that there are potentially dozens, if not hundreds of cases or more of this false-positive carotene "isomer," which was supposed to represent β-carotene, but has, through a typographic error, represented a "new" and non-existent form of carotene, ß-carotene. This clearly represents erroneous literature that needs correction.

Observational Study
Association of phase angle with hospital-acquired functional decline in older patients undergoing cardiovascular surgery.
The aim of this study was to examine whether preoperative phase angle (PhA) measured by bioelectrical impedance analysis was associated with a hospital-acquired functional decline in older patients undergoing cardiovascular surgery. ⋯ PhA was associated with hospital-acquired functional decline in older patients undergoing cardiovascular surgery. PhA is likely to be a comprehensive indicator of physical health that indicates nutritional status, physical function, and geriatric syndrome (frailty/sarcopenia), and is an important predictor of hospital-acquired functional decline in this group of older patients.
