According to EN 1504-10 and ACI Concrete Repair Manual, bond strength and interface quality are the main features of repair system necessary to be assessed. Pull-off test is most commonly used for bond strength evaluation but growing interest in nondestructive techniques (NDT) is recently noted. Impact-echo (IE) is treated as the most promising one for this purpose. The aim of this paper is to analyze an effect of bond quality on stress wave propagation in repair systems. A group of samples has been prepared in order to obtain repair systems of different bond quality. Prior to repair, quality of concrete substrates has been characterized according different techniques: compressive strength, superficial cohesion, surface roughness index and cracking quantification. Than a polymer-modified repair mortar has been applied. After hardening, IE signals have been recorded and pull-off bond strength determined. The relationships between parameters characterizing surface quality, bond strength, IE frequency spectrum and results of wavelet analysis of IE signal have been analyzed. [less ▲]

The effectiveness of a specific educational programme involving the use of a real-time glucose-sensor system (Guardian RT) to improve glucose control was investigated in patients with poorly controlled type 2 diabetes despite insulin therapy. Ten patients participated in a randomized crossover study comparing two 3-month periods, during which glucose levels were monitored by either self-monitoring of blood glucose (SMBG) alone or by Guardian RT (restricted to 1 week per month) in addition to SMBG. Only four of the enrolled patients completed both periods, while dropouts were mainly due to technical difficulties in using the device. All six patients who completed the first 3-month period showed a reduction in glycated haemoglobin (HbA(1c)) level whatever the mode of glucose monitoring (study effect). A further reduction in HbA(1c) level was observed in two of the three patients using the Guardian RT during the second period. Less frequent symptomatic hypoglycaemic episodes were noted during the 3-month period with the device in the four patients who completed both study periods. These limited, but promising, results of this pilot study appear to justify the initiation of a larger study to assess the use of a real-time glucose sensor in carefully selected patients with type 2 diabetes.

A proportion of chronic headache patients become refractory to medical treatment and severely disabled. In such patients various neurostimulation methods have been proposed, ranging from invasive procedures such as deep-brain stimulation to minimally invasive ones like occipital nerve stimulation. They have been applied in single cases or small series of patients affected with varying headache disorders: cervicogenic headache, hemicrania continua, posttraumatic headache, chronic migraine, and cluster headache. Although favorable results were reported overall, it is premature to consider neurostimulation as a treatment with established utility in refractory headaches. At present, the most detailed clinical studies have been performed in intractable chronic cluster headache (iCCH) patients, who represent about 1% of all chronic cluster headache (CCH) patients. Various lesional interventions have been attempted in these patients, none with lasting benefits. In recent years, non-destructive neurostimulation methods have raised new hope. Hypothalamic deep-brain stimulation (hDBS) acts rapidly and has lasting efficacy, but is not without risk. Occipital nerve stimulation (ONS) was studied in two trials on a total of 17 iCCH patients. Clinical efficacy was found to be very satisfactory by most patients and by the investigators. Although slightly less efficacious than hDBS, ONS has the advantage of being rather harmless and reversible. At this stage, it should be preferred as first-line invasive therapy for iCCH. Recent case reports mention the efficacy of supraorbital (SNS) and vagal (VNS) nerve stimulation. Whether these neurostimulation methods have a place in the management of iCCH patients remains to be determined. [less ▲]

This study examined the influence of emotional valence on the production of DRM false memories (Roediger & McDermott, 1995). Participants were presented with neutral, positive or negative DRM lists for a later recognition (Experiment 1) or recall (Experiment 2) test. In both experiments, confidence and recollective experience (i.e., “Remember-Know” judgements; Tulving, 1985) were also assessed. Results consistently showed that, compared with neutral lists, affective lists induced more false recognition and recall of non presented critical lures. Moreover, although confidence ratings did not differ between the false remembering from the different kinds of lists, “Remember” responses were more often associated with negative than positive and neutral false remembering of the critical lures. In contrast, positive false remembering of the critical lures was more often associated with “Know” responses. These results are discussed in light of the Paradoxical Negative Emotion (PNE) hypothesis (Porter et al., 2008). [less ▲]

Plus de cinquante ans après leur mise sur le marché, les sulfamidés hypoglycémiants font toujours partie du traitement de base du diabète non insulinodépendant. A côté de leurs remarquables propriétés pharmacologiques, ces produits ont, à différentes reprises, été tenus responsables d’hypoglycémies sévères survenant de manière inexpliquée chez des sujets non diabétiques. Ce type d’hypoglycémie, qualifiée de factice, est notamment fréquemment retrouvée dans le syndrome de Munchausen, trouble psychiatrique poussant le malade à mimer une pathologie. Cette hypoglycémie est associée à un hyperinsulinisme endogène simulant une pathologie endocrine très rare, l’insulinome. Nous souhaitons faire connaître aux Cliniciens l’intérêt de la recherche et du dosage sanguin des sulfamidés hypoglycémiants dans le cadre du diagnostic différentiel des hyperinsulinismes. La mise en évidence d’une hypoglycémie induite par ces médicaments constitue un élément intéressant pour orienter le diagnostic et éventuellement éviter une pancréatectomie en cas de forte suspicion d’insulinome. La méthode analytique développée au laboratoire s’appuie sur la chromatographie liquide ultra performante couplée à la spectrométrie de masse tandem (UPLC -MS -MS ). Par cette technique, on peut mettre en évidence dans le sang une dizaine de sulfonylurées et le répaglinide. Elle constituera à l’avenir une méthode de choix face à toute suspicion de mésusage des sulfonylurées. [less ▲]

Central nervous system (CNS) dysfunction is thought to be pivotal in migraine, and could occur at several levels: the brain (the cortex and its connections with subcortical nuclei), the brainstem, and even peripheral structures (e.g., trigeminal ganglion and nerve). As it is particularly suited to functional evaluation of various components of the nervous system, neurophysiological testing has become a valuable tool for investigating migraine pathophysiology and the effects of pharmacological treatment. However it has limited value for migraine diagnosis because of a high interindividual variability. In this chapter, we critically review and summarize the available published literature on neurophysiological approaches in migraine, i.e., electroencephalography, evoked and event-related potentials, transcranial magnetic stimulation (TMS), electromyography, and cerebellar testing. The most relevant techniques for understanding migraine pathophysiological mechanisms are highlighted. [less ▲]

OBJECTIVES: To examine how geriatric evaluation and management units (GEMUs) are organized and to examine the effectiveness of admission on a GEMU. DESIGN: Systematic review and meta-analysis based on literature search of multiple databases and the references lists of all identified articles and by contacting authors. SETTING: GEMUs. PARTICIPANTS: Elderly people admitted to a GEMU. MEASUREMENTS: Quality of the studies was assessed on 10 criteria. The outcome parameters were mortality, institutionalization, functional decline, readmission, and length of stay at different follow-up points. A random-effects meta-analysis was performed using Hedges' gu and variance of relative risk (RR). RESULTS: GEMUs are organized in a heterogeneous way and the included studies gave no thorough description of comprehensive geriatric assessment (CGA). Involvement of a multidisciplinary team was a key element in all GEMUs. The individual trials showed that admission to a GEMU has one or more favorable effects on the outcomes of interest, with two significant effects in the meta-analysis: less functional decline at discharge from the GEMU (RR=0.87, 95% confidence interval (CI)=0.77-0.99; P=.04) and a lower rate of institutionalization 1 year after discharge (RR=0.78, CI=0.66-0.92; P=.003). For the other outcomes in the meta-analysis, a GEMU did not induce significantly different outcomes than usual care. CONCLUSION: This meta-analysis shows a significant effect in favor of the GEMU group on functional decline at discharge and on institutionalization after 1 year. There is heterogeneity between the studies, poor quality of some randomized controlled trials, and shortage of information about CGA. Multidisciplinary CGA offered in a GEMU may add value to the care for frail older persons admitted to the hospital, but the limitations confirm the need for well-designed studies using explicit CGA and more-structured and -coherent assessment instruments such as the Minimum Data Set Resident Assessment Instrument.
