RESUMEN

We assessed the quality of online health and nutrition information using a Google™ search on "supplements for cancer". Search results were scored using the Health Information Quality Index (HIQI), a quality-rating tool consisting of 12 objective criteria related to website domain, lack of commercial aspects, and authoritative nature of the health and nutrition information provided. Possible scores ranged from 0 (lowest) to 12 ("perfect" or highest quality). After eliminating irrelevant results, the remaining 160 search results had median and mean scores of 8. One-quarter of the results were of high quality (score of 10-12). There was no correlation between high-quality scores and early appearance in the sequence of search results, where results are presumably more visible. Also, 496 advertisements, over twice the number of search results, appeared. We conclude that the Google™ search engine may have shortcomings when used to obtain information on dietary supplements and cancer.

RESUMEN

Diabetes mellitus (DM) is a highly prevalent condition that causes significant morbidity and mortality in the United States and worldwide. Conventional therapies include lifestyle modification, oral pharmacological agents, and subcutaneous insulin. Emerging data suggest that natural approaches to the treatment of DM may help supplement current therapies for further glycemic control. Herein, we review the evidence of several natural modalities for DM treatment. We describe the pathophysiology of diabetes and its complications, provide an overview of current pharmacologic treatments, and finally, discuss natural approaches to diabetes management. Specifically, we will describe on the utility of diet, physical activity, and common natural products in the treatment of DM and focus on recent, high-quality studies. Adverse effects and potential interactions of each therapy will be highlighted where applicable.

RESUMEN

Type 2 diabetes mellitus (DM) is a significant cause of premature complications and mortality in patients with cardiovascular disease (CVD). In addition to lifestyle modifications, conventional treatment of DM consists of oral hypoglycemic agents, insulin sensitizers, and subcutaneous insulin. In diabetic individuals with or at risk for CVD, aspirin and statin therapy reduce CVD morbidity and mortality. Several natural or herbal supplements have shown potential benefit in patients with CVD and DM. We provide an overview of the current guidelines for treatment of DM and CVD. We then review the literature to describe the efficacy of natural approaches to CVD risk reduction in diabetic patients, with a focus on physical activity, dietary modification, and natural/herbal supplements. Activity and diet improve cardiovascular outcomes in patients with CVD and DM. Natural and herbal supplements have potential for benefit but require further research to determine their efficacy and safety.
