RESUMEN
OBJECTIVE: The objective of this study is to compare complication rates between peripherally inserted central catheters (PICCs) and peripherally inserted non-central catheters (PINCCs) in the neonatal intensive care unit (NICU). STUDY DESIGN: A retrospective, observational study was conducted. The PICCs were catheters whose tip terminated in the vena cavae, and PINCCs were defined as those whose tip fell short of this location. Complication rates were assessed using generalized estimating equations modeling. RESULT: A total of 91 PINCCs and 889 PICCs were placed in 750 neonates. In all, 44.0% of PINCCs had a major complication compared with 25.2% of PICCs (P=0.0001). The unadjusted (unadj.) complication rate among PINCCs was 51.7 per 1000 line days and 15.9 for PICCs (unadj. rate ratio: 3.25; 95% confidence interval (CI): 2.32, 4.55). After adjusting for multiple confounders, the risk remained significantly higher for PINCCs (adjusted odds ratio: 2.41; 95% CI: 1.33, 4.37). CONCLUSION: The rate of associated complications with the use of PINCCs in the NICU population is more than twice that of the PICCs.

OBJECTIVE: To compare clinical outcomes of premature infants on synchronized nasal intermittent positive pressure ventilation (SNIPPV) vs nasal intermittent positive pressure ventilation (NIPPV) in the neonatal intensive care unit. Use of NIPPV in the neonatal intensive care unit has shown promise with better clinical outcomes in premature neonates. It is not known if synchronization makes a significant clinical impact when using this technique. STUDY DESIGN: Retrospective data were obtained (1/04 to 12/09) of infants who received NIPPV anytime during their stay in the neonatal intensive care unit. SNIPPV (Infant Star with StarSync) was utilized from 2004 to 2006, whereas NIPPV (Bear Cub) was used from 2007 to 2009. Bronchopulmonary dysplasia (BPD) was defined using the NIH consensus definition. Unadjusted associations between potential risk factors and BPD/death were assessed using the χ (2) or Wilcoxon rank-sum test. Adjusted analyses were performed using generalized linear mixed models, taking into account correlation among infants of multiple gestation. RESULT: There was no significant difference in the mean gestational age and birth weight in the two groups: SNIPPV (n=172; 27.0w; 1016 g) and NIPPV (n=238; 27.7w; 1117 g). There were no significant differences in maternal demographics, use of antenatal steroids, gender, multiple births, small for gestational age or Apgar scores in the two groups. More infants in the NIPPV group were given resuscitation in the delivery room (SNIPPV vs NIPPV: 44.2 vs 63%, P<0.001). Use of surfactant (84.4 vs 70.2%; P<0.001) was significantly higher in the SNIPPV group. There were no differences in the rate of patent ductus arteriosus, intraventricular hemorrhage, periventricular leukomalacia, retinopathy of prematurity and necrotizing enterocolitis in the two groups. After adjusting for the significant variables, use of NIPPV vs SNIPPV (odds ratio 0.74; 95% confidence interval: 0.42, 1.30) was not associated with BPD/death. CONCLUSION: These data suggest that use of SNIPPV vs NIPPV is not significantly associated with a differential impact on clinical outcomes.

AIMS/HYPOTHESIS: A high but normal fasting plasma glucose level in adults is a risk factor for future development of type 2 diabetes mellitus and cardiovascular disease. We investigated whether normal fasting plasma glucose levels (<5.60 mmol/l) are associated with decreases in insulin sensitivity and beta cell function, as well as an adverse cardiovascular profile in obese youth. METHODS: We performed a cross-sectional analysis in a multiethnic sample of 1,020 obese youth (614 girls and 406 boys; mean age 12.9 years [CI 95% 12.7-13.1], BMI z score 2.34 [CI 95% 2.31-2.38]) with normal fasting plasma glucose. All participants had a standard OGTT, with calculation of indices of insulin sensitivity and beta cell function. For the analysis, prepubertal and pubertal participants were stratified into quartiles of normal fasting plasma glucose. RESULTS: We observed a significant increase in fasting insulin and AUC 2 h glucose across quartiles. Pronounced changes were observed in insulin sensitivity and secretion, particularly in the pubertal group. Moreover, the odds of presenting with impaired glucose tolerance increased by 4.5% with each 0.06 mmol/l increase in fasting plasma glucose. No significant differences in cardiovascular indices were seen across quartiles. CONCLUSIONS/INTERPRETATION: These data suggest that in obese youth, independent of age, BMI z score, sex, family history and ethnicity, insulin sensitivity and secretion decline when moving from low to high normal fasting plasma glucose. The simple measure of fasting plasma glucose could assist clinicians in identifying children for targeted diabetes screening and subsequent lifestyle management.

The objective of this study was to determine how accurately teens can report miles driven. Participants were 118 drivers in Connecticut (average age 17(1/2) years; average time licensed 11 months). Half had their own vehicle; half shared family vehicles. Teens completed a telephone survey about their preceding week's driving, then completed a daily trip log for the next week and a second survey about the details of the logged week's trips and miles. Teens with their own vehicle provided odometer readings. Summing the miles for every trip was generally consistent with estimates from odometer readings. Overall mileage estimates were 20-30% lower than those from trip-by-trip listings, except for very low estimates for the first week by teens who shared vehicles. The results indicate that single overall estimates frequently understate total miles driven, but that prompted reviews of each trip can provide valid and detailed information.
