Harnessing nature's therapeutic potential: A review of natural products in prostate cancer management

Prostate cancer is the most commonly diagnosed cancer and the second leading cause of cancer-related death among men in the United States. The global burden of this disease is rising, placing significant strain on healthcare systems worldwide. Although definitive therapies like surgery and radiation are often effective, prostate cancer can recur and progress to castration-resistant prostate cancer in some cases. Conventional treatments for prostate cancer often have substantial side effects that can greatly impact patients' quality of life. Therefore, many patients turn to complementary therapies to improve outcomes, manage side effects, and enhance overall well-being. Natural products show promise as complementary treatments for prostate cancer, offering anticancer properties with a low risk of adverse effects. While preclinical research has produced encouraging results, their role in prostate cancer treatment remains controversial, largely due to inconsistent and limited success in clinical trials. This review explores the mechanisms of action of key natural products in prostate cancer management and summarizes clinical trials evaluating their efficacy and safety. It underscores the need for high-quality, rigorously designed, and adequately powered studies to validate the therapeutic potential and safety of these supplements in cancer care. Additionally, we propose future directions to enhance their role in addressing the complex challenges associated with prostate cancer.

Bariatric endoscopic-surgical therapies for NAFLD. Should they be considered viable options among current treatments?

Nowadays, non-alcoholic fatty liver disease is one of the first causes of liver transplant worldwide; many efforts have been done to find the perfect drug for this multifactorial disease. Presently we just have a few drugs that could be used in specific and limited clinical scenarios. Current evidence suggests that bariatric endoscopic and surgical therapies could be strategies with optimal outcomes, with high impact in quality of life, decrease of cardiovascular risk, and improvement in metabolic profile, despite being considered expensive procedures. This review proposes to consider these therapies early together with liver fibrosis evaluation, with long term cost-effectiveness benefits in the absence of response to lifestyle modifications and pharmacological treatments.

Vitamin E in Cancer Treatment: A Review of Clinical Applications in Randomized Control Trials

Vitamin E, along with other vitamins and micronutrients play a range of physiologic roles in the homeostasis of the body. Moreover, they also have postulated therapeutic roles that are often incompletely studied and understood. In this scoping review, we explored the recent randomized control trials (RCTs) of Vitamin E in the context of cancer, to investigate whether Vitamin E has a therapeutic role. We searched major bibliographic electronic databases to identify sixteen RCTs studying the role of Vitamin E in cancer management that have been published in the last ten years. These studies had different methodological qualities, including some that used Vitamin E in combination with other treatments. Furthermore, due to the heterogenous results, it is difficult to make a consensus statement on the effectiveness of Vitamin E in cancer therapeutics. In some cases, there were even suggestion of detriment with Vitamin E supplementation. Therefore, well designed, large, prospective RCTs are needed studying pure isoforms of Vitamin E to establish the safety and efficacy of this dietary supplement.
