With anesthesia awareness as a model of study we debate the both fascinating and dangerous phenomenon called consciousness fluctuation that takes place during surgical anesthesia. In accordance with current scientific knowledge this paradox is the consequence of our limits in both precise knowledge of anesthesia mechanisms and our inability to accurately assess the level of anesthesia with brain monitoring. We also focus on the relationships between memory and anesthesia, as well as the possibility of interfering with memory during general anesthesia.

To assess whether maintenance of labor epidural analgesia using programmed intermittent epidural bolus (PIEB) is associated with reduced local anesthetic (LA) consumption, patient-controlled epidural analgesia (PCEA) use, and rescue analgesia requirements compared to continuous epidural infusion (CEI). ⋯ The epidural maintenance regimen used (CEI vs. PIEB) was not associated with differences in LA consumption, motor blockade or delivery mode. Main limitations of the study include its single center retrospective design and the fact that patients were not randomized to treatment groups.

The tyrosine kinase inhibitor (TKI) bosutinib has demonstrated activity in patients with advanced phase chronic myeloid leukemia (CML), but effects on health-related quality of life (HRQoL) remain unexplored. This study evaluated HRQoL in advanced CML patients receiving bosutinib in an ongoing phase 2 study following resistance or intolerance to prior imatinib therapy. ⋯ NCT00261846.

Multicenter Study
Association between hypoglycemia risk and hemoglobin A1C in patients with type 2 diabetes mellitus.
To better manage type 2 diabetes mellitus (T2DM), the tradeoff between improved glycemic control and hypoglycemia should be evaluated. The purpose of this study was to assess the relationship between hypoglycemia and hemoglobin A1c (HbA1c) in a real-world population. ⋯ Lower HbA1c level was associated with higher hypoglycemia prevalence among S.U.-treated patients. HbA1c level should be taken into consideration when reporting hypoglycemia prevalence.

Many patients with type 2 diabetes mellitus (T2DM) require insulin therapy. If basal insulin fails to achieve glycemic control, insulin intensification is one possible treatment intensification strategy. We summarized clinical data from randomized clinical trials designed to compare the efficacy and safety of basal-bolus and premixed insulin intensification regimens. ⋯ Of the four trials that reported a significant difference between regimens in bodyweight change, two favored basal-bolus therapy and two favored premixed insulin. Thus, on a population level, neither basal-bolus therapy nor premixed insulin showed a consistent advantage in terms of glycemic control, hypoglycemic risk, or bodyweight gain. It is therefore recommended that clinicians should adopt an individualized approach to insulin intensification - taking into account the benefits and risks of each treatment approach and the attitude and preferences of each patient - in the knowledge that both basal-bolus and premixed regimens may be successful.
