Multicentric evaluation of eight glucose and four ketone blood meters.

Objectives: High precision meters for blood glycemia are mandatory for monitoring glucose status in patients, avoiding both hypo- and hyper-glycemia. Health care providers routinely used in both out- and in-patients point-of-care measurements of glucose and ketone. These measurements, frequently used for medical decisions, are known to be less accurate than those performed in laboratories.

[Evaluation of the quality of clinical practice guidelines published in the Annales de Biologie Clinique with the help of the EFLM checklist].

Several tools are available to help evaluate the quality of clinical practice guidelines (CPG). The AGREE instrument (Appraisal of guidelines for research & evaluation) is the most consensual tool but it has been designed to assess CPG methodology only. The European federation of laboratory medicine (EFLM) recently designed a check-list dedicated to laboratory medicine which is supposed to be comprehensive and which therefore makes it possible to evaluate more thoroughly the quality of CPG in laboratory medicine.

Low-dose interleukin 2 in patients with type 1 diabetes: a phase 1/2 randomised, double-blind, placebo-controlled trial.

Background: An improper balance of regulatory/effector T (Treg/Teff) cells is central to the development of autoimmune diseases, including type 1 diabetes. We previously showed that low-dose interleukin 2 (IL2) induced Treg cell expansion and activation and clinical improvement in patients with hepatitis-C-virus-induced vasculitis. We aimed to establish which low doses of IL2 would be safe and induce Treg cells in patients with type 1 diabetes, considering that: (1) type 1 diabetes might be linked to alteration of the IL2/IL2R activation pathway; (2) activation of pathogenic Teff cells by IL2 could exacerbate disease; and (3) the safety of low-dose IL2 is not known in type 1 diabetes.

Critical Appraisal of Microbiology Guidelines Endorsed by two Professional Organisations: Société Française De Microbiologie (SFM) and American Society of Microbiology (ASM).

Medical practice guidelines (GLs) being tools that are mainly designed to evaluate medical professionals, it sounds logical, and fair, that professionals should in turn evaluate GLs. Microbiology being a medical discipline, we used the AGREE instrument, i.e.

Atorvastatin decreases computed tomography and S100-assessed brain ischemia after subarachnoid aneurysmal hemorrhage: a comparative study.

Objective: Statins, which improve the bioavailability of endogenous nitric oxide and upregulate endothelial nitric oxide synthase, have been used to prevent cerebral vasospasm after aneurysmal subarachnoid hemorrhage. The objective of this study was to determine whether statin therapy diminished vasospasm-induced ischemia as assessed using daily measurements of serum S100B, a biomarker for cerebral ischemia, and computed tomography measurement of ischemic lesion volume.

Design: Single-center study of cases and historical controls.

[Evaluation of the AFSSAPS clinical practice guidelines on prevention and treatment of thrombo-embolic disease in medicine (2009), in comparison with those of the American College of Chest Physicians (ACCP 2008) with the help of the AGREE tool].

We have evaluated the methodological quality of the AFSSAPS French clinical practice guidelines on prevention and treatment of thrombo-embolic disease in medicine, published in 2009. We have evaluated in parallel the similar recommendations from north-America on the subject (ACCP 2008). Our evaluation tool was the AGREE instrument which is consensual at an international level, in particular at the WHO (World Health Organisation) and at the European Union.

[Evaluation of the methodological quality of the Rémic (microbiology guidelines - bacteriology and mycology) of the Société française de microbiologie].

We have evaluated the methodological quality of the Rémic (microbiology guidelines - bacteriology and mycology) of the Société française de microbiologie (edition2007), using to AGREE criteria, which are consensual at an international level, in particular at the the World Health Organisation (WHO) and at the European Union. The methodological quality of the Rémic appears to be sub-optimal. These shortcomings in quality are mainly observed in AGREE domain n° 5 (applicability), in AGREE item n° 5 (patients' opinions were not considered), and in AGREE item n° 23 (conflicts of interest were not declared).

[Multicenter evaluation of the reliability of five blood glucose monitoring systems].

As part of a tender AP-HP Paris Hospitals, an assessment of the reliability record of five blood glucose monitoring systems (BGMSs) (Optium Xceed (Abbott), Contour TS (Bayer), One Touch Ultra (Lifescan), Stat Strip Xpress (Nova) and Accu Check (Roche) and an evaluation of their sensitivity to changes in hematocrit were conducted in 4 hospitals of Paris. In terms of inaccuracy, all BGMSs have submitted CV repetability under the limits of acceptability. One BGMS (Lifescan) presented a CV of reproducibility outside limit of acceptability (13.

Changing electrolyte and acido-basic profile in HIV-infected patients in the HAART era.

Background: HIV-infected patients may develop a variety of underreported metabolic abnormalities that may be classified into HIVAN, specific HIV abnormalities, coincidental renal disorders and anti-retroviral-treatment-induced side effects.

Methods: Our descriptive cross-sectional study evaluates the prevalence of electrolyte and acid base disorders in HIV patients in the HAART era in a tertiary care teaching hospital. All consecutive HIV-infected patients (n = 1,232) presenting at our Department of Infectious Disease over 3 months were included.

A different approach to analyzing age-related HbA1c values in non-diabetic subjects.

Using appropriate statistical tests and taking into account the analytical performance of hemoglobin A1c (HbA1c) measurements, is it useful to establish HbA1c age-related values in non-diabetic subjects? Non-diabetic subjects (n=135, 72 women and 63 men) from the neuromuscular department of the Pitié-Salpétrière Hospital (Paris) were involved in our study. Subjects were divided into two groups related to age: 51 patients under 50 years old and 84 subjects aged 50 years or more. Fasting plasma glucose and HbA1c measurements were respectively performed by enzymatic assay using the hexokinase method and high-performance liquid chromatography based on the ion exchange methodology with high precision.
