- The detection of acrylamide, classified as a probable human carcinogen, in commonly consumed foods created public health alarm. Thus far, only 2 epidemiologic studies have examined the effect of dietary acrylamide on cancer risk. Presently, we reanalyzed data from a large population-based Swedish case-control study of renal cell cancer. Food frequency data were linked with national food databases on acrylamide content, and daily acrylamide intake was estimated for participants. The risk of renal cell cancer was evaluated for intake of food items with elevated acrylamide levels and for total daily acrylamide dose. Adjusting for potential confounders, there was no evidence that food items with elevated acrylamide, including coffee (OR(highest vs. lowest quartile) = 0.7; 95% CI = 0.4-1.1), crisp breads (OR(highest vs. lowest quartile) = 1.0; 95% CI = 0.6-1.6) and fried potatoes (OR(highest vs. lowest quartile) = 1.1; 95% CI = 0.7-1.7), were associated with a higher risk of renal cell cancer risk. Furthermore, there was no association between estimated daily acrylamide intake through diet and cancer risk (OR(highest vs. lowest quartile) = 1.1; 95% CI = 0.7-1.8; p for trend = 0.8). The results of this study are in line with the 2 previous studies examining dietary acrylamide and suggest there is no association between dietary acrylamide and risk of renal cell cancer.

- BACKGROUND & AIMS: Postoperative metabolism is characterised by insulin resistance and a negative whole-body nitrogen balance. Preoperative carbohydrate treatment reduces insulin resistance in the first day after surgery. We hypothesised that preoperative oral carbohydrate treatment attenuates insulin resistance and improves whole-body nitrogen balance 3 days after surgery. METHODS: Fourteen patients undergoing total hip replacement were double-blindly randomised to preoperative oral carbohydrate treatment (12.5%, 800 + 400 ml, n = 8) or placebo (n = 6). Glucose kinetics (6,6-D2-glucose), substrate utilisation (indirect calorimetry) and insulin sensitivity (hyperinsulinaemic-euglycaemic clamp) were measured preoperatively and on the third day after surgery. Nitrogen losses were monitored for 3 days after surgery. Values are mean (SEM). Analysis of variance (ANOVA) statistics were used. RESULTS: Endogenous glucose release during insulin infusion increased after surgery in the placebo group. Preoperative carbohydrate treatment, as compared to placebo, significantly attenuated postoperative endogenous glucose release (0.69 (0.07) vs. 1.21 (0.13)mg kg(-1) x min(-1), P < 0.01), while whole-body glucose disposal and nitrogen balance were similar between groups. CONCLUSIONS: While insulin resistance in the first day after surgery has previously been characterised by reduced glucose disposal, enhanced endogenous glucose release was the main component of postoperative insulin resistance on the third postoperative day. Preoperative carbohydrate treatment attenuated endogenous glucose release on the third postoperative day.
