Canakinumab (ACZ885) vs triamcinolone acetonide for treatment of acute flares and prevention of recurrent flares in gouty arthritis patients refractory to or contraindicated to nsaids and/or colchicine.

Purpose: Current treatments for arthritis flares in gout (gouty arthritis) are not effective in all patients and may be contraindicated in many due to underlying comorbidities. Urate crystals activate the NALP 3 inflammasome which stimulate production of IL-1β, driving inflammatory processes. Targeted IL-1β blockade may be an alternative treatment for gouty arthritis. Canakinumab (ACZ885) is a fully human monoclonal anti- IL-1β antibody with a long half-life (28 days). Method: This was an 8-weeks, dose-ranging, multicenter, blinded, double-dummy, active-controlled trial of patients ≥18 to ≤80 y with an acute gouty arthritis flare, refractory to or contraindicated to NSAIDs and/or colchicine. Patients were randomized to 1 subcutanous (sc) dose of canakinumab (10, 25, 50, 90, or 150 mg) or 1 intra muscular (im) dose of triamcinolone acetonide (TA) [40 mg]. The primary variable was assessed 72 h post-dose, measured on a 0-100 mm VAS pain scale. Secondary variables included pain intensity 24 and 48 h post dose, time to 50% reduction in pain intensity, and time to recurrence of gout flares up to 8 weeks post dose. Results: 200 patients were enrolled (canakinumab n=143, TA n=57) and 191 completed the study. A statistically significant dose response was observed at 72 h. The 150 mg dose reached superior pain relief compared to TA starting from 24h: estimated mean difference in pain intensity on 0-100 mm VAS was -11.5 at 24 h, -18.2 at 48 h, and -19.2 at 72 h (all p<0.05). Canakinumab 150 mg provided a rapid onset of pain relief: median time to 50% reduction in pain was reached at 1 day with canakinumab 150 mg vs 2 days for the TA group (p=0.0006). The probability of recurrent gout flares was 3.7% with canakinumab 150 mg vs. 45.4% with TA 8 weeks post treatment, a relative risk reduction of 94% (p=0.006). Serious AEs occurred in 2 patients receiving canakinumab (appendicitis and carotid artery stenosis) and 1 receiving TA (cerebrovascular disorder). Investigator's reported these events as not study drug related. There were no discontinuations due to AEs. Conclusion: Canakinumab 150 mg provided faster onset and superior pain relief compared to TA for acute flares in gouty arthritis patients refractory to or contraindicated to standard treatments. The 150 mg dose of canakinumab prevented recurrence of gout flares with a relative risk reduction compared to TA of 94% at 8 weeks post-dose, and was well tolerated.

Treatment of ruptured abdominal aortic aneurysm, a permanent challenge or a waste of resources? Prediction of outcome using a multi-organ-dysfunction score.

OBJECTIVES: in a retrospective study, attempts have been made to identify individual organ-dysfunction risk profiles influencing the outcome after surgery for ruptured abdominal aortic aneurysms. METHODS: out of 235 patients undergoing graft replacement for abdominal aortic aneurysms, 57 (53 men, four women, mean age 72 years [s.d. 8.8]) were treated for ruptured aneurysms in a 3-year period. Forty-eight preoperative, 13 intraoperative and 34 postoperative variables were evaluated statistically. A simple multi-organ dysfunction (MOD) score was adopted. RESULTS: the perioperative mortality was 32%. Three patients died intraoperatively, four within 48 h and 11 died later. A significant influence for pre-existing risk factors was identified only for cardiovascular diseases. Multiple linear-regression analysis indicated that a haemoglobin <90 g/l, systolic blood pressure <80 mmHg and ECG signs of ischaemia at admission were highly significant risk factors. The cause of death for patients, who died more than 48 h postoperatively, was mainly MOD. All patients with a MOD score >/=4 died (n=7). These patients required 27% of the intensive-care unit (ICU) days of all patients and 72% of the ICU days of the non-survivors. CONCLUSION: patients with ruptured aortic aneurysms from treatment should not be excluded. However, a physiological scoring system after 48 h appears justifiable in order to decide on the appropriateness of continual ICU support.

Prevalence, awareness and treatment of type 2 diabetes mellitus in Switzerland : the COLAUS study

Le diabète de type 2 (DT2) a une prévalence élevée dans les pays industrialisés, et on s'attend à une augmentation dans les années à venir en raison du vieillissement de la population ainsi que des modifications du mode de vie. Il existe malheureusement peu de données épidémiologiques sur la prévalence et la prise en charge du diabète en Suisse. Les objectifs de cette étude étaient donc 1) évaluer la prévalence du DT2 dans une cohorte lausannoise ; 2) caractériser la prise en charge des patients atteints de DT2, et 3) identifier les facteurs associés à la prévalence, la connaissance par les patients de leur maladie et le traitement du DT2. Pour ce faire, 6181 sujets (3246 femmes), âgés de 35 à 75 ans et vivant à Lausanne ont été inclus dans l'étude. La prévalence totale du DT2 était de 6.3% (intervalle de confiance à 95%: 5.7-7.0%), une valeur comparable à celle des pays avoisinants. La prévalence était plus élevée chez les hommes que chez les femmes (9.1% contre 3.8%, p<0.001), et augmentait avec l'âge. Deux tiers des patients avec DT2 (65.3% ; 60.4-70.0%) avaient connaissance de leur situation, et plus de trois-quarts d'entre eux étaient traités. Les hommes étaient plus fréquemment traités que les femmes (91.3% contre 75.9%, p<0.001). La plupart des patients suivait une monothérapie (majoritairement par biguanides). Parmi les sujets avec une thérapie multiple, une prévalence plus élevée de glycémie à jeun >7 mmol/1 était présente. L'analyse multivariée a montré que le sexe masculin, l'âge croissant et un indice de masse corporelle élevé étaient associés à une plus grande prévalence du DT2, alors qu'aucune association n'a été trouvée pour l'activité physique et la consommation d'alcool. Parmi les sujets atteints de DT2, l'âge croissant était positivement associé à la connaissance du diabète, de même que l'âge croissant et le sexe masculin étaient associés à une plus grande prévalence du traitement. Le faible taux de connaissance de diabète pourrait être dû à un manque de dépistage par les médecins de premier recours. La présence d'autres facteurs de risque cardiovasculaire devrait inciter les médecins à un dépistage du diabète pour obtenir un meilleur profil de risque. Cette étude a des limitations. D'abord, aucune mesure de l'hémoglobine glyquée n'a été mesurée, et par conséquent la détermination de la prise en charge uniquement par la glycémie à jeun peut être difficile. Ensuite, le taux de participation était bas et pourrait limiter l'interprétation des résultats ; néanmoins, il est comparable à celui d'autres études effectuées dans les pays occidentaux. Il existe peu de données épidémiologiques du DT2 en Suisse, cette étude permet donc d'évaluer la situation actuelle et de déterminer la prévalence et la prise en charge du diabète à Lausanne à travers la cohorte CoLaus. Une telle étude a par conséquent son importance dans le contexte actuel, au vu du vieillissement de la population et de l'augmentation des facteurs de risque cardio-vasculaires.

Detection of HIV drug resistance during antiretroviral treatment and clinical progression in a large European cohort study.

OBJECTIVE(S): To investigate the relationship between detection of HIV drug resistance by 2 years from starting antiretroviral therapy and the subsequent risk of progression to AIDS and death. DESIGN: Virological failure was defined as experiencing two consecutive viral loads of more than 400 copies/ml in the time window between 0.5 and 2 years from starting antiretroviral therapy (baseline). Patients were grouped according to evidence of virological failure and whether there was detection of the International AIDS Society resistance mutations to one, two or three drug classes in the time window. METHODS: Standard survival analysis using Kaplan-Meier curves and Cox proportional hazards regression model with time-fixed covariates defined at baseline was employed. RESULTS: We studied 8229 patients in EuroSIDA who started antiretroviral therapy and who had at least 2 years of clinical follow-up. We observed 829 AIDS events and 571 deaths during 38,814 person-years of follow-up resulting in an overall incidence of new AIDS and death of 3.6 per 100 person-years of follow-up [95% confidence interval (CI):3.4-3.8]. By 96 months from baseline, the proportion of patients with a new AIDS diagnosis or death was 20.3% (95% CI:17.7-22.9) in patients with no evidence of virological failure and 53% (39.3-66.7) in those with virological failure and mutations to three drug classes (P = 0.0001). An almost two-fold difference in risk was confirmed in the multivariable analysis (adjusted relative hazard = 1.8, 95% CI:1.2-2.7, P = 0.005). CONCLUSION: Although this study shows an association between the detection of resistance at failure and risk of clinical progression, further research is needed to clarify whether resistance reflects poor adherence or directly increases the risk of clinical events via exhaustion of drug options.

Prevalence, predictors, and consequences of long-term refusal of antipsychotic treatment in first-episode psychosis.

OBJECTIVE: Studies investigating medication adherence in psychosis are limited by the need of a certain degree of medication adherence and the inclusion of mostly multiple-episode patients. By contrast, noninformed consent, epidemiological studies in first-episode psychosis (FEP) allow the assessment of an important subgroup of patients who persistently refuse antipsychotic medication and thereby never receive an adequate antipsychotic trial. The present study aims to assess the prevalence and predictors of such a "medication refusal" subgroup and its association with illness outcome. METHODS: The present file audit study assessed medication adherence in an epidemiological cohort of 605 FEP patients who were treated within the Early Psychosis Prevention and Intervention Centre for up to 18 months. Medication adherence was categorized into full adherence, nonadherence, and persistent medication refusal. Predictors were analyzed using logistic regression models. RESULTS: During the 18-month treatment period, 204 patients (33.7%) were fully adherent, 287 (47.4%) displayed at least 1 phase of nonadherence, and 114 patients (18.8%) were persistent medication refusers. Poor premorbid functioning, comorbid substance use, and poor insight predicted both medication refusal and nonadherence; a forensic history and no previous contact to psychiatric care were specifically predictive of medication refusal. With respect to illness outcome, nonadherent patients were worse off when compared with fully adherent patients, and medication refusers were even worse off compared with nonadherent patients. CONCLUSIONS: Within a nonselected epidemiological FEP cohort, almost 20% of patients are persistent medication refusers. The found predictors may help to identify the individual risk of persistent medication refusal and may enable an early (preventive) treatment adaptation.

Expérience de dix ans de réanimation chirurgicale d'un centre hospitalier universitaire. Détermination d'un critère d'identification des patients à risque de décéder de coagulopathie irréversible [10 years experience in surgical resuscitation at a university hospital center. Determination of a criterion for identifying patients at risk for fatal irreversible coagulopathy]

The authors evaluated ten years of surgical reanimation in the University Centre of Lausanne (CHUV). Irreversible coagulopathy (IC) is the predominant cause of death for the polytraumatized patient. Acidosis, hypothermy, and coagulation troubles are crucial elements of this coagulopathy. The authors looked for a criterion allowing the identification of dying of IC. In a retrospective study, laboratory results of pH, TP, PTT, thrombocyte count and the need for blood transfusion units were checked for each major step of the primary evaluation and treatment of the polytraumatized patients. These results were considered as critical according to criteria of the literature (30). The authors conclude that the apparation of a third critical value may be useful to identify the polytraumatized patient at risk of dying of IC status. This criterion may also guide the trauma team in selecting a damage control surgical approach (DCS). This criterion was then introduced into an algorithm involving the Emergency Department, the operating room and the Intensive Care Unit. This criterion is a new tool to address the patient at the crucial moment to the appropriate hospital structure.

Iowa D.O.T's Experience with Recycling Portland Cement Pavement and Asphalt Cement Pavement, MLR-77-4, 1977

This report provides details of IADOT's experience removing and crushing asphaltic concrete and portland cement concrete for recycling. The recycled material was used on interstate highways for the subbase and shoulders. The major problem IADOT encountered on this project was the removal of reinforcing steel from the broken concrete. The contractor used hydraulic powered shears to clip off all protruding steel during the removal and loading of the concrete on the grade. This project took place in 1977.

Détermination de l'antigène HLA-G soluble dans le liquide folliculaire et dans le milieu de culture d'embryons comme indicateur du succès d'un traitement par FIV-ICSI [Soluble human leukocyte antigen-G (sHLA-G) in follicular fluid and embryo culture medium and its impact on pregnancy prediction in IVF-ICSI treatment]

In IVF around 70% of embryos fail to implant. Often more than one embryo is transferred in order to enhance the chances of pregnancy, but this is at the price of an increased multiple pregnancy risk. In the aim to increase the success rate with a single embryo, research projects on prognostic factors of embryo viability have been initiated, but no marker has found a routine clinical application to date. Effects of soluble human leukocyte antigen-G (sHLA-G) on both NK cell activity and on Th1/Th2 cytokine balance suggest a role in the embryo implantation process, but the relevance of sHLA-G measurements in embryo culture medium and in follicular fluid (FF) are inconsistent to date. In this study, we have investigated the potential of sHLA-G in predicting the achievement of a pregnancy after IVF-ICSI in a large number of patients (n = 221). sHLA-G was determined in media and in FF by ELISA. In both FF and embryo medium, no significant differences in sHLA-G concentrations were observed between the groups "pregnancy" and "implantation failure", or between the groups "ongoing" versus "miscarried pregnancies". Our results do not favour routine sHLA-G determinations in the FF nor in embryo conditioned media, with the current assay technology available.

Défaillances respiratoires aiguës d'origine neuromusculaire [Acute respiratory failure due to neuromuscular disorders].

Numerous acute and chronic neuromuscular disorders may induce an acute ventilatory failure. The latter is sometimes triggered by a complication like a bronchial aspiration, a pneumonia, or an atelectasis. The acute ventilatory failure often develops insidiously and may be missed until the terminal event. Four different clinical presentations are depicted in this review: slowly progressive (Duchenne muscular dystrophy), rapidly progressive (Guillain-Barré syndrome), chronic with exacerbations (myasthenia gravis), and a form consecutive to critical care (critical care polyneuropathy and myopathy). For each type of ventilatory failure, the review discusses the preventive surveillance, the treatment of acute respiratory failure, and the long-term management.

The Brief Psychiatric Rating Scale (version 4.0) factorial structure and its sensitivity in the treatment of outpatients with unipolar depression.

The 24-item Brief Psychiatric Rating Scale (BPRS, version 4.0) enables the rater to measure psychopathology severity. Still, little is known about the BPRS's reliability and validity outside of the psychosis spectrum. The aim of this study was to examine the factorial structure and sensitivity to change of the BPRS in patients with unipolar depression. Two hundred and forty outpatients with unipolar depression were administered the 24-item BPRS. Assessments were conducted at intake and at post-treatment in a Crisis Intervention Centre. An exploratory factor analysis of the 24-item BPRS produced a six-factor solution labelled "Mood disturbance", "Reality distortion", "Activation", "Apathy", "Disorganization", and "Somatization". The reduction of the total BPRS score and dimensional scores, except for "Activation", indicates that the 24-item BPRS is sensitive to change as shown in patients that appeared to have benefited from crisis treatment. The findings suggest that the 24-item BPRS could be a useful instrument to measure symptom severity and change in symptom status in outpatients presenting with unipolar depression.
