RESUMO

PURPOSE: Poor nutrition is highly implicated in the pathogenesis of cancer and affects the survival of patients during and after completion of definitive therapies. Mechanistic evidence accumulated over the last century now firmly places dysregulated cellular energetics within the emerging hallmarks of cancer. Nutritional intervention studies often aim to either enhance treatment effect or treat nutritional deficiencies that portend poor prognoses. Patients living within food priority areas have a high risk of nutritional need and are more likely to develop comorbidities, including diabetes, hypertension, renal disease, and cardiovascular risk factors. Unfortunately, there is currently a paucity of data analyzing the impact of food priority areas on cancer outcomes. METHODS: Therefore, we performed a review of the literature focusing on the molecular and clinical interplay of cancer and nutrition, the importance of clinical trials in elucidating how to intervene in this setting and the significance of including citizens who live in food priority areas in these future prospective studies. CONCLUSIONS: Given the importance of nutrition as an emerging hallmark of cancer, further research must be aimed at directing the optimal nutrition strategy throughout oncologic treatments, including the supplementation of nutritious foods to those that are otherwise unable to attain them.

RESUMO

Background: Food recommendations to improve cancer prevention are generally based on epidemiologic data and remain inconsistent. These epidemiologic studies, while controversial, have generally produced results that caution against the consumption of high-fat foods, including eggs, red meat, and full-fat dairy, such as butter and cheese. Yet, limited data exist assessing the quality of individual sources of these foods and the effect each has after its consumption. This study set out to assess the impact sources of food within the same groups from animals raised differently on variables associated with health in human studies. Methods and Materials: A search was conducted through MEDLINE, Embase, and PubMed. In total, twenty-nine studies met inclusion criteria, measuring physiologic changes in humans after consuming animal products following animal diet manipulation. A meta-analysis was attempted to assess the differences between the cohorts in these studies, but was aborted due to poor study quality, vast differences in study design, and a limited number of studies. Results: Studies varied by animal, animal diet manipulation, food product, and overall design. Significant differences were present between groups eating the same food (cheese, beef, eggs, and butter) from animals raised differently, including levels of: conjugated linoleic acid, omega-3 fatty acids (alpha linoleic acid [ALA], docosahexaenoic acid [DHA], and eicosapentaenoic acid [EPA]), and inflammatory factors (triacyl glycerol [TAG], interleukin-6 [IL-6], interleukin-8 [IL-8], tumor necrosis factor [TNF], and C-reactive protein [CRP]). Lipid levels were minimally affected. Conclusions: This work highlights differences in human health markers after consumption of the same foods from animals raised differently. Overall, lipid levels remained relatively neutral, but significant changes in inflammatory and other serum markers and phospholipids were present. Future studies and dietary recommendations should consider how animals are raised, as this can produce different effects on health markers.

RESUMO

OBJECTIVE: The Veterans Health Administration is the largest integrated health care system fully funded through the US government; however, compliance with government dietary recommendations within Veterans Affairs (VA) hospitals is not well known. The aim of this study was to determine which foods are available at VA hospitals and whether these foods comply with government recommendations. METHODS: Process verification for a Freedom of Information Act request was used to assess government-run inpatient and outpatient VA hospital facilities by accessing the location, quantity, and contents of vending machines. These foods and beverages were then quantified and compared with the US Department of Agriculture Dietary Guidelines for Americans 2015-2020 (eighth edition). RESULTS: Of the beverages supplied, 49% contained >55 g of sugar, supplying >10% of daily calories in added sugar in a single serving. Of all beverages, 50% contained >50 g of added sugar (range 17-77 g per bottle/can). The 65 available food items were comprised of 28% candy, 14% potato chips/puffed corn snacks, 11% pastries/frosted baked goods, 11% crackles/pretzels, and 8% nuts/trail mix, and the remainder consisted of jerky, pork rinds, gum, and popcorn. Nuts/trail mix and granola-items meeting nutritional guidelines-comprised five and three options in total, respectfully. CONCLUSIONS: All VA Hospitals contain vending machines providing a majority of soda, candy, and junk foods that directly conflict with healthy food choice recommendations from US governing health bodies. Few sources meeting US dietary guidelines are available in vending machines at these government-run facilities, which serve as poor examples for patients who are attempting to follow a healthy diet.

RESUMO

In our manuscript, we present the food choices available at vending machines in government-run Veterans Affairs Hospitals. The data in this article includes both a quantification of the beverages and packages foods available, along with a comparison of recommendations and sugar content to the government-issued USDA Dietary Guidelines 2015-2020. For further discussion on the results of this study, refer to the full manuscript "Lead by Poor Example: An Assessment of Snacks, Soda, and Junk Food Availability in Veterans Affairs Hospitals" (Champ et al., 2018) [1].

RESUMO

BACKGROUND: We report on a patient with human immunodeficiency virus (HIV)-positive disease with a primary orbital melanoma treated with surgery and adjuvant radiation. METHODS: A 53-year-old woman with HIV-positive disease presented with left-sided progressive ipsilateral vision loss and proptosis. An MRI scan revealed a mass-enhancing lesion measuring 2.1 × 2.6 × 2.5 cm abutting the optic nerve. The patient underwent left orbital exenteration with temporalis flap reconstruction, pathology revealing malignant melanoma, stage T1N0M0. Posterior margins were positive and lymphovascular invasion was present; therefore, the patient received adjuvant radiation to a total dose of 70 Gy in 35 fractions. RESULTS: The patient remains with no evidence of disease (NED) at a follow-up time of 3.5 years. CONCLUSION: Surgery remains the mainstay of treatment in patients with primary orbital melanomas, and adjuvant radiotherapy should be considered for those with positive margins or other risk factors for recurrence. We present a patient with significant risk factors with NED at 3.5-year follow-up.
