Oxidative stress is a key component in linking environmental toxicity to the multistage carcinogenic process. Reactive oxygen species (ROS) are generated in response to both endogenous and exogenous stimuli. To counterbalance ROS-mediated injury, an endogenous antioxidants defense system exists; however, when oxidation exceeds the control mechanisms, oxidative stress arises. ⋯ Much debate has arisen about whether antioxidant supplementation alters the efficacy of cancer chemotherapy. There is still limited evidence in both quality and sample size, suggesting that certain antioxidant supplements may reduce adverse reactions and toxicities. Significant reductions in toxicity may alleviate dose-limiting toxicities so that more patients are able to complete prescribed chemotherapy regimens and thus, in turn, improve the potential for success in terms of tumor response and survival.

Muscle disuse is often observed after injury or during periods of illness, resulting in the loss of muscle mass and strength, with sometimes debilitating consequences. Although substantial advancements have been made in determining the mechanisms responsible for the etiology of muscle disuse atrophy in rodents, only in recent years have studies of any significant number focused on reaffirming these findings in humans. In this review, we discuss the processes responsible for disuse atrophy as based on current evidence and highlight where gaps in our knowledge persist. Furthermore, given the emphasis placed on resistance exercise and nutrition as potential therapeutic countermeasures, we consider recent advancements in the study of resistance exercise and nutrition in the stimulation of muscle protein synthesis and the associated implications when devising effective treatment strategies.

Review Meta Analysis
Soy isoflavone supplementation could reduce body weight and improve glucose metabolism in non-Asian postmenopausal women--a meta-analysis.
The objective of this study was to conduct a systematic review and a meta-analysis to confirm the effects of soy isoflavone supplementation on body weight, fasting glucose, and insulin level in non-Asian postmenopausal women. ⋯ This meta-analysis showed soy isoflavone supplementation could be beneficial for body weight reduction, glucose, and insulin control in plasma. Large and well-designed studies are recommended to confirm this conclusion.

Malnutrition continues to be under-recognized and undertreated in the hospitalized setting. Although no "gold standard" for the diagnosis of malnutrition exists, the Subjective Global Assessment (SGA) is a commonly used malnutrition assessment tool. The study aim was to explore the reporting of inter-rater reliability (IRR) of the SGA when used as a nutritional assessment tool in the published literature. ⋯ The IRR is rarely reported in the published literature and has not yet been reported across experience levels.
