[EX 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).
[EX A]: Do early postoperative alterations in infant energy use increase the risk of overfeeding?

[EX Q]: With advances in medicine, the subjective assessment of patients on hemodialysis regarding their quality of life (QOL) is gaining importance. Clinicians cannot rely solely on objective markers, such as the rates of complications and mortality, when evaluating responses to dialysis. In clinical settings, laboratory values are used as measures of patients' health. However, the relationship between clinical laboratory values and QOL has not been elucidated yet. Therefore, the present study aimed to define the relationship of laboratory values and patient attributes to the QOL of outpatients on hemodialysis in order to obtain basic data for reevaluating nursing support for patients on hemodialysis in the future.", 'The participants were 44 outpatients receiving hemodialysis at Hospital B. The QOL was surveyed using a self-administered questionnaire, the Kidney Disease Quality of Life Short Form. The following patient attributes and laboratory values were taken from the medical records: age; sex; primary disease; number of years on hemodialysis; complications; number of hours of hemodialysis per session; percentage weight gain; cardiothoracic ratio; blood pressure; hematocrit; and the serum levels of albumin, potassium, phosphorus, and calcium.', 'The serum potassium level significantly affected mental health, social functioning, symptoms, and the effect of kidney disease, with the 3.5-5.0 mEq/L target range group scoring higher than the > or =5.1 mEq/L group.

[EX Q]: Three-session days were introduced in our endoscopy unit to accommodate the increased demand resulting from the introduction of the National Health Service Bowel Cancer Screening Programme (BCSP). Cecal intubation rate (CIR) and adenoma detection rate (ADR) may decline with time during a standard working day, but data are lacking for an extended three-session day. We assessed colonoscopy performance in an extended three-session day.', 'Colonoscopies performed during the year 2011 were retrospectively analyzed. The CIR and ADR were analyzed according to the time of day when procedures were done: morning (AM), afternoon (PM), or evening (EVE). Because of an expected higher incidence of adenomas in the BCSP patients, ADR was analyzed according to indication (BCSP or non-BCSP).', 'Of the 2574 colonoscopies, 1328 (51.7%) were in male patients and 1239 (48.3%) in female patients with a median age of 63 years (interquartile range [IQR], 51-70). Of the 2574 colonoscopies, 1091 (42.4%) were performed in AM lists, 994 (38.6%) in PM lists, and 489 (19%) in EVE lists. Time of day did not affect the CIRs for the AM, PM, and EVE lists (90.5%, 90.1%, and 89.9%, respectively; (2) [2, N=2540]=0.15, P=0.927). The CIR was reduced in female patients and those with poor bowel preparation (P<0.05). After exclusion of the BCSP patients, the ADR was lower in the EVE lists than in the AM and PM lists on univariate analysis, but on multivariate analysis, this difference was not significant (P>0.05). The ADR was significantly higher in patients older than 60 years and in men (P<0.001). Queue position did not independently influence the CIR or ADR.
