Intensive insulin therapy to maintain blood glucose at or below 6.11 mM reduces morbidity and mortality after cardiac surgery and morbidity in medical intensive care unit (ICU) patients. The authors ...investigated the clinical safety and outcome effects of intensive insulin therapy compared to conventional insulin therapy in patients receiving postoperative intensive care after neurosurgical procedures.
In this prospective randomized controlled trial, 483 patients undergoing elective or emergency brain surgery were prospectively and randomly assigned either to intensive insulin therapy (241 patients), receiving insulin titrated to maintain blood glucose levels within the range of 4.44-6.11 mM, or to conventional insulin therapy (242 patients), receiving insulin to maintain blood glucose levels below 11.94 mM. Primary endpoint was incidence of hypoglycemia (defined as blood glucose < 2.78 mM). Efficacy measures included the length of ICU stay, infection rate, and 6 months follow-up Glasgow outcome scale score and overall survival.
Hypoglycemia episodes were more frequent in patients receiving intensive insulin therapy, median (min-max): 8 (0-23) versus 3 (0-4); P < 0.0001. The length of stay in the ICU was shorter (6 vs. 8 days; P = 0.0001), and the infection rate was lower (25.7% vs. 39.3%; P = 0.0018). Glasgow outcome scale score and overall survival at 6 months were similar in the two groups.
Intensive insulin therapy in patients admitted to a postoperative neurosurgical ICU after brain surgery is associated with iatrogenic hypoglycemia, but it can also reduce the infection rate and shorten the ICU stay.
Postoperative delirium can result in increased postoperative morbidity and mortality, major demand for postoperative care and higher hospital costs. Hypnotics serve to induce and maintain anaesthesia ...and to abolish patients' consciousness. Their persisting clinical action can delay postoperative cognitive recovery and favour postoperative delirium. Some evidence suggests that these unwanted effects vary according to each hypnotic's specific pharmacodynamic and pharmacokinetic characteristics and its interaction with the individual patient.We designed this study to evaluate postoperative delirium rate after general anaesthesia with various hypnotics in patients undergoing surgical procedures other than cardiac or brain surgery. We also aimed to test whether delayed postoperative cognitive recovery increases the risk of postoperative delirium.
After local ethics committee approval, enrolled patients will be randomly assigned to one of three treatment groups. In all patients anaesthesia will be induced with propofol and fentanyl, and maintained with the anaesthetics desflurane, or sevoflurane, or propofol and the analgesic opioid fentanyl.The onset of postoperative delirium will be monitored with the Nursing Delirium Scale every three hours up to 72 hours post anaesthesia. Cognitive function will be evaluated with two cognitive test batteries (the Short Memory Orientation Memory Concentration Test and the Rancho Los Amigos Scale) preoperatively, at baseline, and postoperatively at 20, 40 and 60 min after extubation.Statistical analysis will investigate differences in the hypnotics used to maintain anaesthesia and the odds ratios for postoperative delirium, the relation of early postoperative cognitive recovery and postoperative delirium rate. A subgroup analysis will be used to categorize patients according to demographic variables relevant to the risk of postoperative delirium (age, sex, body weight) and to the preoperative score index for delirium.
The results of this comparative anaesthesiological trial should whether each the three hypnotics tested is related to a significantly different postoperative delirium rate. This information could ultimately allow us to select the most appropriate hypnotic to maintain anaesthesia for specific subgroups of patients and especially for those at high risk of postoperative delirium.

Neurogenic bowel dysfunction (NBD) is an impairment of defecation control due to any nervous system lesion negatively affecting physical health status and quality of life. We aimed at systematically ...assessing all available evidence on NBD treatment in adults and providing clinical management guidance and recommendations.
PICOs and questions (N.=7) were identified by an expert panel. We searched for and retrieved evidence from the PUBMED and EMBASE databases, limited to the English language and the Western countries context, related to any type of setting and published from 2009 to 2019. Health effects, patient values, preferences and resource use were assessed. Of all, only RCTs, observational studies and systematic reviews on adult population (≥18 years) were analyzed. The study was conducted according to PRISMA guidelines and Cochrane recommendations. The effect size, if possible, was calculated for the interpretation of the outcomes, and evidence was assessed through the GRADE method.
Thirty-one studies were included in our qualitative synthesis. Evidence is generally scarce. Most of the outcomes are narratively described and therefore defined by imprecision. Besides, most of the included studies are affected by risk of bias. Digital stimulation was found to be effective in short term follow-up. The pharmacological treatment choice, combined or alone, needs to be balanced case by case considering clinical history, setting of use and bowel management protocol. According to only one RCT supporting evidence mainly in persons affected by spinal cord injury (SCI), trans-anal irrigation (TAI) improves QoL and patient independency with a significant reduction of time spent for defecation and daily bowel program. History of urinary infections predicts the choice of using TAI. Patient-reported efficacy of colostomy alone or in combination with other surgeries appears evident in terms of patient's satisfaction and QoL over time. Nonetheless, perioperative and late complications can occur and may result in reduced acceptability over time.
Evidence is somehow weak and mainly reported in SCI. The systematic use of assistive interventions does not reduce the need of conservative or invasive approaches. Studies are needed on the role of bowel management in protecting patients from complications secondary to NBD in long term follow-ups.
Between 1996 and 2000, 90 newly diagnosed adult patients with T-acute lymphoblastic leukemia (T-ALL) were registered in the Gruppo Italiano Malattie Ematologiche dell'Adulto (GIMEMA) Leucemia Acuta ...Limfoide (LAL) 0496 protocol. Cases were centrally processed for morphology, immunophenotype, cytogenetics, molecular biology, and multidrug resistance (MDR). Twenty-two patients were females and 68 were males. Four percent of cases were pro-T, 47% pre-T, 39% cortical T, and 10% mature T-ALL. Fifty-six percent of patients with pro-T + pre–T-ALL achieved complete remission (CR) compared with 91% for cortical + mature cases (P = .002). CD34 expression was associated with a significantly lower CR rate: 54% versus 84% (P = .009). Thirty-one (36.5%) of 85 patients had an abnormal karyotype, the most common abnormality (15%) being a partial del(6q). The cytogenetic profile did not impact on CR achievement. MDR1 function, present in 26% of cases, correlated significantly with CR achievement (P = .004). A highly significant (P = .001) difference in CR rate was observed between patients who did not express the CD13/CD33/CD34 antigens and were MDR functionally negative (96%) compared with patients positive for at least one of these markers (57%). Multivariate analysis showed an impact on CR achievement for CD33 expression and MDR1 function. An extensive biologic workup of adult T-ALL cases at presentation is recommended in order to design tailored therapeutic strategies aimed at improving CR rates.
