IMPORTANCE: Evidence supporting the choice of intravenous colloid vs crystalloid solutions for management of hypovolemic shock remains unclear. OBJECTIVE: To test whether use of colloids compared with crystalloids for fluid resuscitation alters mortality in patients admitted to the intensive care unit (ICU) with hypovolemic shock. DESIGN, SETTING, AND PARTICIPANTS: A multicenter, randomized clinical trial stratified by case mix (sepsis, trauma, or hypovolemic shock without sepsis or trauma). Therapy in the Colloids Versus Crystalloids for the Resuscitation of the Critically Ill (CRISTAL) trial was open label but outcome assessment was blinded to treatment assignment. Recruitment began in February 2003 and ended in August 2012 of 2857 sequential ICU patients treated at 57 ICUs in France, Belgium, North Africa, and Canada; follow-up ended in November 2012. INTERVENTIONS: Colloids (n = 1414; gelatins, dextrans, hydroxyethyl starches, or 4% or 20% of albumin) or crystalloids (n = 1443; isotonic or hypertonic saline or Ringer lactate solution) for all fluid interventions other than fluid maintenance throughout the ICU stay. MAIN OUTCOMES AND MEASURES: The primary outcomewas death within 28 days. Secondary outcomes included 90-day mortality; and days alive and not receiving renal replacement therapy, mechanical ventilation, or vasopressor therapy. RESULTS: Within 28 days, there were 359 deaths (25.4%) in colloids group vs 390 deaths (27.0%) in crystalloids group (relative risk [RR], 0.96 [95% CI, 0.88 to 1.04]; P = .26). Within 90 days, there were 434 deaths (30.7%) in colloids group vs 493 deaths (34.2%) in crystalloids group (RR, 0.92 [95% CI, 0.86 to 0.99]; P = .03). Renal replacement therapy was used in 156 (11.0%) in colloids group vs 181 (12.5%) in crystalloids group (RR, 0.93 [95% CI, 0.83 to 1.03]; P = .19). There were more days alive without mechanical ventilation in the colloids group vs the crystalloids group by 7 days (mean: 2.1 vs 1.8 days, respectively; mean difference, 0.30 [95% CI, 0.09 to 0.48] days; P = .01) and by 28 days (mean: 14.6 vs 13.5 days; mean difference, 1.10 [95% CI, 0.14 to 2.06] days; P = .01) and alive without vasopressor therapy by 7 days (mean: 5.0 vs 4.7 days; mean difference, 0.30 [95% CI, -0.03 to 0.50] days; P = .04) and by 28 days (mean: 16.2 vs 15.2 days; mean difference, 1.04 [95% CI, -0.04 to 2.10] days; P = .03). CONCLUSIONS AND RELEVANCE: Among ICU patients with hypovolemia, the use of colloids vs crystalloids did not result in a significant difference in 28-day mortality. Although 90-day mortality was lower among patients receiving colloids, this finding should be considered exploratory and requires further study before reaching conclusions about efficacy. Source

Aim: This study aimed to assess the effectiveness of continuous glucose monitoring (CGM) for glucose control in type 1 diabetic patients treated by continuous subcutaneous insulin infusion (CSII) and presenting with frequent hypoglycaemic episodes. Methods: Thirteen patients with type 1 diabetes (diabetes duration: 25±15 years; CSII duration: 5.5±7.0 years), with more than six recorded capillary blood glucose (CBG) values <60mg/dL, according to their metres for the past 14 days, were offered the permanent use of a CGM device (Guardian RT®, Medtronic) plus ongoing self-monitoring of blood glucose (SMBG) for 12 weeks, followed by a 12-week crossover period of SMBG only, or vice versa. Glucose control, determined by recorded 14-day CBG values <60mg/dL and HbA1c levels, and quality of life according to the Diabetes Quality of Life (DQOL) questionnaire, were assessed at baseline, and after 12- and 24-week follow-ups. Results: Four patients withdrew from the study during the first period (of whom three were using CGM). In the nine study completers, the number of low CBG values decreased significantly from 13.9±9.2 to 7.6±6.8 (P=0.011) when patients used CGM, in either the initial or final trial period, while a decrease in HbA1c from 8.3±0.7 to 7.7±0.6% (P=0.049) was also observed, in contrast to the absence of any significant differences during the SMBG-only period. DQOL scores were also essentially unaffected. Conclusion: This pilot observational study supports the hypothesis that CGM use can significantly improve overall glucose control while reducing hypoglycaemic episodes in hypoglycaemia-prone type 1 diabetic patients treated by CSII. © 2010 Elsevier Masson SAS.

We report clinical outcomes following transcatheter aortic valve implantation (TAVI), using the CoreValve revalving system (18 Fr transfemoral or subclavian) or the Edwards Sapien valve (22 Fr transfemoral or 24 Fr transapical) as part of a Belgian prospective nonrandomized multicentre registry. All 15 Belgian centres performing TAVI participated to this registry (seven exclusively Edwards Sapien, eight exclusively CoreValve). All consecutive high-risk symptomatic patients with severe aortic stenosis were evaluated by a heart team and screened for eligibility for TAVI. Three hundred and twenty-eight patients underwent TAVI with CoreValve (n=141; eight subclavian and 133 transfemoral) or Edwards Sapien (n=187; 99 transfemoral and 88 transapical) up to April 2010. Procedural success was 97%. Onemonth survival was 88% for the Edwards and 89% for the CoreValve treated patients. One-month mortality was both related to cardiac and non-cardiac reasons. Overall one-year survival was 78% in the CoreValve transfemoral treated patients, 100% in the CoreValve subclavian treated patients, 82% in the Edwards transfemoral treated patients and 63% in the Edwards transapical treated patients. This mid-term mortality was mainly related to age-related, non-cardiac complications. © 2011 Published by European Association for Cardio-Thoracic Surgery. All rights reserved. Source


The concept of "polypill" for cardiovascular prevention was introduced in 2003 in a landmark paper of the British Medical Journal. A model based on results provided by evidence-based medicine suggested that a «polypill», that contains a statin, three blood pressure lowering drugs (each at half standard dose), aspirin and folic acid, would result in an 80 % reduction in the incidence of coronary and cerebrovascular events, while being associated with a good tolerance profile and offering a favourable cost-effectiveness ratio. The present paper aims at presenting the new advances dealing with this new paradigm in cardiovascular prevention. We will present the progresses of the "polypill" concept since 2003, the results of a first controlled clinical trial, the pharmaceutical feasibility for routine clinical use and the potential pharmaco-economical impacts of such a strategy. The "polypill" may offer a solution to avoid physician's clinical inertia and reduce patients's lack of compliance, two drawbacks in the field of cardiovascular prevention. Source


Numerous patients with type 2 diabetes have renal impairment, especially in the elderly population. Metformin, the first choice oral glucose-lowering agent, is classically contraindicated in case of chronic kidney disease of stages 3-5 (creatinine clearance 60 ml/min/1.73 m), because of a risk of accumulation of the biguanide that may lead to lactic acidosis. Hence numerous patients with some degree of renal impairment are being treated with metformin in clinical practice, apparently without any harm. In contrast, several observational studies have shown that they may clinically bene-fit from this therapy, including with a significant reduction of all-cause mortality when compared to patients not receiving metformin. Thus, an increasing number of physicians plea for revisiting the official criteria of contraindication to the use of metformin in case of renal insufficiency. The present paper discusses this controversy and insists upon the mandatory cautions to be taken when using metformin in a diabetic patient with moderate (stage 3) chronic kidney disease (metformin being contraindicated in case of severe renal impairment - stages 4-5).
