Q: Our previous in-vivo and in-vitro studies demonstrated that inflammation accelerated the progression of atherosclerosis via the dysregulation of the low-density lipoprotein receptor (LDLr) pathway. The current study aimed to investigate the effects and their underlying mechanisms of inflammation on lipid accumulation in the radial arteries of endstage renal disease (ESRD) patients with arteriovenostomy.', '30 ESRD patients with arteriovenostomy were included. The patients were divided into two groups based on their plasma levels of C-reactive protein: a control (n = 16) and an inflamed group (n = 14). The expression of tumor necrosis factor-alpha (TNF-alpha) and monocyte chemotactic protein-1 of the radial arteries were increased in the inflamed group. Foam cell formation and lipid droplet accumulation were examined by hematoxylin and eosin (H & E) and Oil Red O staining. Intracellular cholesterol trafficking-related proteins were examined by immunohistochemistry and immunofluorescent staining.', 'There was significant lipid accumulation in the radial arteries of the inflamed group compared with the control. Further analysis demonstrated that this accumulation was correlated with the increased protein expression of LDLr, sterol regulatory element-binding protein-2 (SREBP-2), and SREBP cleavageactivating protein (SCAP). Confocal microscopy showed that inflammation enhanced the translocation of SCAP escorting SREBP-2 from the endoplasmic reticulum to the Golgi, thereby activating LDLr gene transcription. Interestingly, upregulated LDLr expression was positively associated with the increased protein expression of mammalian target of rapamycin (mTOR), which had enhanced coexpression with SREBP-2. This finding suggests that the activation of mTOR may be involved in LDLr pathway disruption through the upregulation of SREBP-2 expression.

A: Does activation of mTOR contribute to foam cell formation in the radial arteries of patients with end-stage renal disease?

Q: Energy needs in infants are decreased after surgery because of growth inhibition (resulting from catabolic stress metabolism), decreased insensible losses, and inactivity. Using standardized formulas that account for growth, activity, and insensible losses during this stress period can lead to overfeeding in excess of 200% of the actual measured requirement. Overfeeding during this acute injury period can result in increased CO2 production from lipogenesis. This study determined the effects of a reduced rate of mixed caloric repletion on infant energy use during the early postoperative period.', 'C-reactive protein (CRP), oxygen consumption (VO2), carbon dioxide production (VCO2), measured energy expenditure (MEE), and total urinary nitrogen (TUN) were measured serially in seven infants (average age, 78 days) during the first 72 hours after abdominal or thoracic surgery. Nonprotein respiratory quotient (RQnp), and values for oxidation of carbohydrate (Ce) and fat (Fe) were calculated. Injury severity was stratified based on serum CRP concentrations of > or = 6.0 mg/dL (high stress) or < 6.0 mg/dL (low stress). Recovery from acute stress was analyzed by comparing studies in which CRP had decreased to < or = 2.0 mg/dL (resolving stress group) with those in which CRP values were greater than 2.0 mg/dL (acute stress group).', 'Average total caloric intake (64.56 +/- 18.51 kcal/kg/d; approximately 50% of predicted energy requirement) exceeded average MEE (42.90 +/- 9.98 kcal/kg/d) by approximately 50%. Average TUN was 0.18 +/- 0.07 g/kg/d (high stress 0.2 +/- 0.05 versus low stress 0.16 +/- 0.09 g/kg/d). Average RQnp was 1.05 +/- 0.13 and average Ce was 37.28 +/- 16.86 kcal/kg/d. The average calculated Fe was 0.0 +/- 12.27 kcal/kg/d, reflecting approximately equal amounts of fat oxidized compared with fat generated from excess glucose (lipogenesis). When individual studies were analyzed at a CRP cutpoint of 2.0 mg/dL, overfeeding (RQ > 1.0) was significantly less likely in the resolving (2/6 studies, 33.4%) versus acute stress (9/13 studies, 69.2%, Z test P < .001) group. Five of seven (5/7) patients (9/19 individual studies) had negative Fe values (average -9.89 +/- 10.02) reflecting net lipogenesis. The RQnp for these nine studies was 1.14 +/- 0.11 versus 0.97 +/- 0.09 for the remaining 10, and this difference was significant (P < .01). A significant correlation existed between carbohydrate intake and VCO2 (Pearson r = .6951, P < .01). In addition, there was a good correlation between carbohydrate intake and VCO2 (Pearson r = .6591, P < .01). The coefficient of variation for MEE was 8.0% (low stress) versus 30.2% (high stress).

A: Do early postoperative alterations in infant energy use increase the risk of overfeeding?

Q: The effect of the interaction between type 2 diabetes and dyslipidemia on inflammation and lipid peroxidation (LPO) has not been assessed.', 'To investigate whether diabetes coupled with dyslipidemia alters oxidative metabolism leading to increased LPO products and inflammatory status.', '100 patients were divided into four groups based upon diabetic and dyslipidemic status: poorly controlled diabetes with dyslipidemia (DM-PC/D), well-controlled diabetes with dyslipidemia (DM-WC/D), normoglycemic individuals with dyslipidemia (NG/D), and normoglycemic individuals without dyslipidemia (NG/ND). Plasma was evaluated for an LPO product (MDA), antioxidant levels and inflammatory cytokines.', 'Diabetics presented significantly higher levels of LPO (p<0.05) and the DM-PC/D had higher levels of proinflammatory cytokines and MDA in the plasma in comparison with normoglycemics (p<0.05). Interestingly IL1-β, IL-6, and TNF-α in DM-WC/D were not statistically different from those in DM-PC/D. Normoglycemic individuals with dyslipidemia presented significantly increased levels of IL-6 and TNF-α when compared to normoglycemic without dyslipidemia (p<0.05). MDA levels were also positively correlated with the presence of DM complications (r=0.42, p<0.01).

Are diabetes and increased lipid peroxidation associated with systemic inflammation even in well-controlled patients?
