Individuals with cancer are affected by a loss of cell membrane integrity due to electrolyte imbalance between the intra- and extracellular fluids. Cell membrane integrity and hydration status can be assessed according to the phase angle (PhA) and the risk for sarcopenia, by using the Strength, Assistance for walking, Rise from a chair, Climb stairs, and Falls (SARC-F) questionnaire. To our knowledge, this approach has not been validated in patients with cancer. The aims of this study were to verify the prevalence of the risk for sarcopenia, and to analyze the association between PhA and the risk for sarcopenia with and without adjustment for extracellular water content. ⋯ We found that 22.5% of patients with cancer presented with a risk for sarcopenia. Additionally, an association between lower PhA values and enhanced risk for sarcopenia highlighted the importance of adequate hydration and evaluation of fluid status via BIA as a new recommendation to prevent sarcopenia.

The coronavirus disease 2019 (COVID-19) pandemic is seriously threatening public health and setting off huge economic crises across the world. In the absence of specific drugs for COVID-19, there is an urgent need to look for alternative approaches. Therefore, the aim of this paper was to review the roles of micronutrients and bioactive substances as potential alternative approaches in combating COVID-19. ⋯ The roles of micronutrients and bioactive substances in the fight against COVID-19 are exciting areas of research. This review may suggest directions for further study.

Obesity is an important cause of morbidity and mortality due to its close association with metabolic disorders including diabetes, cardiovascular diseases, and certain types of cancer. According to the Developmental Origins of Adult Health and Disease hypothesis, obesity is likely caused by epigenetic changes. Recent studies have shown an association between epigenetic dysregulation of certain genes and obesity. ⋯ These phytochemicals are known for their antioxidant effects but they also modify epigenetic mechanisms. These phytochemicals may have a therapeutic potential in the management of obesity. The aim of this study was to review the epigenetic effects of certain phytochemicals on the expression of obesity-related genes.

Malnutrition plays a critical role in the onset and progress of the coronavirus disease 2019 (COVID-19). The aim of the present study was to explore the association of the prognostic nutritional index (PNI) score with the severity of COVID-19 and its predictive value of the severe form of COVID-19. ⋯ Poorer nutritional status predisposed patients infected with COVID-19 to its severe form. Independently associated with the severity of COVID-19, PNI score could serve as a simple, fast, and effective predictor among patients with different sex, age, and BMI.

Randomized Controlled Trial
Nomogram based on nutritional and inflammatory indicators for survival prediction of small cell carcinoma of the esophagus.
Small cell carcinoma of the esophagus (SCCE) is a rare type of esophageal cancer, and the parameters for prediction of SCCE outcome are unclear. This study aimed to construct a nomogram to predict the outcome of SCCE. ⋯ A nomogram based on nutrition- and inflammation-related indicators was developed to predict the survival of patients with SCCE.
