RESUMO
BACKGROUND: Adequate colon preparation is a critical component of high-quality colonoscopy especially for inpatients undergoing colonoscopy for acute indications. Inpatient colonoscopy has a high incidence of inadequate preparations. We report implementation of a multifaceted quality improvement intervention to improve inpatient colonoscopy preparations. METHODS: Bowel preparation quality from inpatient colonoscopies performed for the 12 months prior to the comprehensive intervention were compared to colonoscopies performed for 12 months following the intervention. The intervention had multiple components including: 1) EMR-based colonoscopy preparation order set; 2) automated EMR alerts prompting nursing assessment of preparation progress; 3) standardized nursing charting processes for tracking preparation progress; and 4) standardized education for nursing staff and ordering providers on adequate colon preparation, assessment of colon preparation quality, and use of the above processes; and print and video patient education materials. RESULTS: Two hundred thirty-eight inpatient colonoscopies were performed in the preintervention assessment period and 163 colonoscopies in the postintervention period. Median preintervention Boston Bowel Preparation Score (BBPS) was 6 and 26% of patients had inadequate colon preparation. Median postintervention BBPS was 8 with 16% inadequate colon preparation (P=0.016). The postintervention group had less ASA class I patients and used a lower dose of fentanyl than the preintervention group. There were no other significant differences between the pre- and postintervention groups. CONCLUSIONS: Implementation of a comprehensive colon preparation quality intervention resulted in significantly improved inpatient colon preparation quality and decreased frequency of inadequate preparations. The intervention consisting of an EMR-based order-set, nursing alerts and charting process, and patient education materials is continually being refined.

NKT cells have been described as innate regulatory cells because of their rapid response to conserved glycolipids presented on CD1d via their invariant TCR. However, little is known about the contribution of the hepatic NKT cell to the development of a local and/or systemic immune response to acute septic challenge (cecal ligation and puncture (CLP)). We found not only that mice deficient in invariant NKT cells (Jalpha18(-/-)) had a marked attenuation in CLP-induced mortality, but also exhibited an oblation of the systemic inflammatory response (with little effect on splenic/peritoneal immune responsiveness). Flow cytometric data indicated that following CLP, there was a marked decline in the percentage of CD3(+)alpha-galactosylceramide CD1d tetramer(+) cells in the mouse C57BL/6J and BALB/c liver nonparenchymal cell population. This was associated with the marked activation of these cells (increased expression of CD69 and CD25) as well as a rise in the frequency of NKT cells positive for both Th1 and Th2 intracellular cytokines. In this respect, when mice were pretreated in vivo with anti-CD1d-blocking Ab, we observed not only that this inhibited the systemic rise of IL-6 and IL-10 levels in septic mice and improved overall septic survival, but that the CLP-induced changes in liver macrophage IL-6 and IL-10 expressions were inversely effected by this treatment. Together, these findings suggest that the activation of hepatic invariant NKT cells plays a critical role in regulating the innate immune/systemic inflammatory response and survival in a model of acute septic shock.

OBJECTIVE: To determine if use of an injection port, the Insuflon, would help to improve glycemic control in youth with type 1 diabetes (TID) who were in suboptimal glycemic control (hemoglobin A1c, HbA1c >8.0%). STUDY DESIGN: A three-arm randomized protocol was used to study the effects of the Insuflon (a subcutaneous injection port) vs. an alarmable blood glucose meter vs. a control group on glycemic control in 66 youth with T1D. All participants used insulin glargine as their basal insulin and the NovoPen Junior with insulin aspart as their rapid-acting insulin. Participants were randomized into control, alarm, or Insuflon groups. HbA1c levels were the primary outcome with values at baseline, 3, and 6 months. RESULTS: Initial parameters were similar in the three groups. HbA1c values were significantly lower for youth who used the Insuflon than for the control group at 3 and 6 months (p = 0.025). The HbA1c values (in %) for youth using the Insuflon decreased significantly from 9.4 at screening to 8.7 at 3 months (p < 0.001) and 8.5 at 6 months (p < 0.001). There were no significant reductions (p > or = 0.05) in the HbA1c values within the other two groups. CONCLUSION: The Insuflon injection port helps some youth with T1D to improve glycemic control.

Sepsis syndrome remains the leading cause of mortality in intensive care units. It is now believed that along with the body's hyperinflammatory response designated to eliminate the underlying pathogen, mechanisms are initiated to control this initial response, which can become deleterious and result in immune dysfunctions and death. A similar state of immune suppression has been described after numerous forms of severe trauma/injury. Although the evidence for immune dysfunctions after sepsis has grown, much remains to be understood about mechanisms underpinning its development and how it acts to increase the morbid state of the critically ill patient. In this context, although the majority of clinical and basic science conducted so far has focused on the roles of myeloid cell populations, the contribution of T lymphocytes and in particular, of regulatory T cells has been somewhat ignored. The studies presented here support the concept that regulatory T lymphocytes (CD4+CD25+ regulatory, gammadelta, and NK T cells) play a role in the control of immune responses and are affected by injury and sepsis. This may be related to their capacity to interact with components of the innate and adaptive immune responses and to their ability to be activated nonspecifically by bacterial products and/or cytokines and to regulate through direct cell-cell and/or soluble mediators. It is our hope that a better understanding of the mechanism through which those rare lymphocyte subsets exert such a profound effect on the immune response may help in improving our ability not only to diagnose but also to treat the critically ill individual.

OBJECTIVE: The aim of this study was to determine whether the use of meal bolus alarms would result in fewer missed meal boluses per week in youth with type 1 diabetes using continuous subcutaneous insulin infusion (CSII) therapy. RESEARCH DESIGN AND METHODS: This was a randomized trial of 48 youth using CSII, who were in suboptimal glycemic control with HbA(1c) (A1C) values > or =8.0%. Twenty-four subjects were randomized to use a Deltec Cozmo insulin pump with meal bolus alarms (experimental group), while the other 24 subjects continued use of their current insulin pumps (control group) without meal bolus alarms. RESULTS: After 3 months of study, the number of missed meal boluses per week was significantly lower in the experimental group (from 4.9 +/- 3.7 to 2.5 +/- 2.5; P = 0.0005) but not significantly lower in the control group (from 4.3 +/- 2.7 to 4.2 +/- 3.9; P = 0.7610). Also after 3 months, the mean A1C value of the experimental group declined significantly (from 9.32 +/- 1.12 to 8.86 +/- 1.10; P = 0.0430). No significant decline in A1C was present for the control group (from 8.93 +/- 1.04 to 8.67 +/- 1.17; P = 0.1940). After 6 months of study, the significant decline in A1C from baseline in the experimental group was no longer present. Pooling of all available data from the control and experimental groups showed that at baseline and 3 and 6 months, the number of missed meal boluses per week was significantly correlated with A1C values. CONCLUSIONS: While meal bolus alarms may have the potential to improve suboptimal glycemic control in youth using CSII, our results demonstrated that these alarms had only a transient, modest effect in doing so.

OBJECTIVE: To determine whether mixing insulin glargine (IG) with a rapid-acting insulin (RAI) analogue in the same syringe had any deleterious effects on glycemic control in children with type 1 diabetes mellitus. STUDY DESIGN: Data from 55 children mixing the IG with a RAI analogue was collected for 6 months before and 6 months after the insulin mixing began. Data from a control group of 55 children not mixing the insulins was collected at similar intervals. Parameters evaluated included hemoglobin A1c (HbA1c) values, number of non-severe and severe hypoglycemic events, number of diabetic ketoacidosis (DKA) events, and blood glucose distribution patterns. RESULTS: After 6 months of study, HbA1c values were equivalent for the control and test groups (8.54+/-1.14 vs 8.61+/-1.14, respectively; P=1.0000). Percentages of blood glucose values in, above, and below the target range did not vary significantly in the groups. There were no significant differences in the groups in the occurrence of non-severe or severe hypoglycemic events or of DKA events. CONCLUSION: There were no significant differences in glycemic control between children who mixed IG in the same syringe with a RAI analogue compared with children who took separate injections.
