RESUMO
OBJECTIVES: To determine the prevalence, risk factors for, and clinical implications of unintentional weight loss on oncologic outcomes in locally advanced cervical cancer (LACC) treated with concurrent chemotherapy and contemporary radiation techniques. METHODS: This a single-institution, retrospective cohort study of patients with LACC who received definitive chemoradiation (CRT) from 2010 to 2015. Clinicopathologic factors were abstracted by chart review and characterized using descriptive statistics. Factors associated with severe weight loss (≥10% from baseline) were determined by Chi-square test. Time-to-event analysis was performed using the Kaplan Meier method and regression was performed using the Cox Proportional hazards model. RESULTS: One hundred and eight patients comprised the cohort. The majority of patients were White, obese, and had squamous histology. Almost 80% of patients experienced at least some weight loss, with 14% of patients experiencing severe weight loss. Patients with FIGO 2009 stage 3 or 4 disease had a 3.4-fold increased risk of severe weight loss compared to those with earlier stage disease. Patients who had severe weight loss had a higher risk for death (HRâ¯=â¯2.37, 95% confidence interval [CI] 1.77, 7.37, pâ¯=â¯0.036) and a trend toward high risk for recurrence (HRâ¯=â¯1.43, 95% CI 0.46, 3.32, pâ¯=â¯0.107) compared to patients without severe weight loss. CONCLUSION: Unintentional weight loss is a common symptom of patients with LACC receiving CRT that affects oncologic outcomes, yet it remains under-recognized. Increased awareness of weight loss and malnutrition may encourage interventions to improve this potentially modifiable risk factor for worse prognosis and quality of life.

Emerging research indicates that nuts are a source of health-promoting compounds demonstrating cardioprotective benefits. However, most studies have assessed the effect of single nuts rather than a nut mixture. The objective of this study was, therefore, to examine the effect of mixed-nut consumption on cardiovascular disease (CVD) risk factors in overweight and obese adults. In a randomized, parallel-arm, controlled trial, 48 participants consumed isocaloric (250 kcal) amounts of pretzels or mixed-nuts. Body weight (BW) (p = 0.024), BMI (p = 0.043), and insulin levels (p = 0.032) were significantly lower in the nut group compared to the pretzel group. Mixed-nut consumption also significantly reduced glucose (p = 0.04) and insulin (p = 0.032) levels after 4 and 8 weeks compared to baseline, respectively. Lactate dehydrogenase of the nut group was significantly lower than the pretzel group (p = 0.002). No significant differences were detected between groups for triglycerides, LDL-C, and HDL-C. However, pretzel consumption increased triglycerides (p = 0.048) from 4 weeks to 8 weeks. Moreover, LDL-C increased (p = 0.038) while HDL-C transiently decreased (p = 0.044) from baseline to 4 weeks. No significant lipid changes were detected within the nut group. Our results suggest that supplementing the diet with mixed-nuts could improve CVD risk factors by improving BW and glucose regulation in comparison to a common carbohydrate-rich snack without promoting the negative effects on lipids detected with pretzels.

Multiple studies have examined the impacts of various nuts on appetitive and metabolic effects; however, fewer studies have addressed the impacts of mixed nuts. The objective was to examine the acute effects of consumption of an isocaloric (253 kcal) snack of mixed nuts or pretzels on appetite hormones, glucose and insulin responses, and subjective appetite ratings in overweight and obese adults. In a two-arm randomized controlled trial, overweight and obese adults consumed either mixed nuts (n = 27) or pretzels (n = 27) with 16 men and 11 women per group. After an overnight fast, blood glucose, insulin, and appetite hormone were measured at baseline and 60 min post snack consumption. Appetite/satiety questionnaires were completed at baseline and 20, 40, 60, 90, 120 min after snack consumption. Both snacks increased satiety and reduced hunger over time. The pretzels group exhibited higher subjective satiety and lower hunger (P < .001) following consumption than the mixed nuts group. Pretzel consumption increased glucose and insulin (P < .001), while no elevation was detected in the mixed nuts at 60 min post snack consumption. Leptin and ghrelin concentrations were significantly lower for the mixed nuts group at 60 min compared with baseline (P < .05). Mixed nuts promote satiety in overweight and obese adults while maintaining stable blood glucose and insulin levels. These results suggest that mixed nuts snack may be beneficial for those who are overweight or obese. Future mixed nuts studies are warranted to examine long-term effects.

BACKGROUND: Although accurate health-related representations of medical situations on television can be valuable, inaccurate portrayals can engender misinformation. OBJECTIVE: The purpose of this study was to compare sociodemographic and medical characteristics of patients depicted on television vs. actual United States (US) Emergency Department (ED) patients. METHODS: Two independently working coders analyzed all 22 programs in one complete year of the popular "emergency room" drama ER. Inter-rater reliability was excellent, and all initial coding differences were easily adjudicated. Actual health data were obtained from the National Heath and Ambulatory Medical Care Survey from the same year. Chi-squared goodness-of-fit tests were used to compare televised vs. real distribution across key sociodemographic and medical variables. RESULTS: Ages at the extremes of age (i.e., ≤ 4 and ≥ 45 years) were less commonly represented on television compared with reality. Characters on television vs. reality were less commonly women (31.2% vs. 52.9%, respectively), African-American (12.7% vs. 20.3%), or Hispanic (7.1% vs. 12.5%). The two most common acuity categories for television were the extreme categories "non-urgent" and "emergent," whereas the two most common categories for reality were the middle categories "semi-urgent" and "urgent." Televised visits compared with reality were most commonly due to injury (63.5% vs. 37.0%, respectively), and televised injuries were less commonly work-related (4.2% vs. 14.8%, respectively). CONCLUSIONS: Comparison of represented and actual characteristics of ED patients may be valuable in helping us determine what types of patient misperceptions may exist, as well as what types of interventions may be beneficial in correcting that potential misinformation.
