Effects of antiresorptive agents on bone micro-architecture assessed by Trabecular Bone Score in women age 50 and older. The Manitoba Prospective Study

Antiresorptive agents such as bisphosphonates induce a rapid increase of BMD during the 1st year of treatment and a partial maintenance of bone architecture. Trabecular Bone Score (TBS), a new grey-level texture measurement that can be extracted from the DXA image, correlates with 3D parameters of bone micro-architecture. Aim: To evaluate the longitudinal effect of antiresorptive agents on spine BMD and on site-matched spine microarchitecture as assessed by TBS. Methods: From the BMD database for Province of Manitoba, Canada, we selected women age >50 with paired baseline and follow up spine DXA examinations who had not received any prior HRT or other antiresorptive drug.Women were divided in two subgroups: (1) those not receiving any HRT or antiresorptive drug during follow up (=non-users) and (2) those receiving non-HRT antiresorptive drug during follow up (=users) with high adherence (medication possession ratio >75%) from a provincial pharmacy database system. Lumbar spine TBS was derived by the Bone Disease Unit, University of Lausanne, for each spine DXA examination using anonymized files (blinded from clinical parameters and outcomes). Effects of antiresorptive treatment for users and non-users on TBS and BMD at baseline and during mean 3.7 years follow-up were compared. Results were expressed % change per year. Results: 1150 non-users and 534 users met the inclusion criteria. At baseline, users and non-users had a mean age and BMI of [62.2±7.9 vs 66.1±8.0 years] and [26.3±4.7 vs 24.7±4.0 kg/m²] respectively. Antiresorptive drugs received by users were bisphosphonates (86%), raloxifene (10%) and calcitonin (4%). Significant differences in BMD change and TBS change were seen between users and nonusers during follow-up (p<0.0001). Significant decreases in mean BMD and TBS (−0.36± 0.05% per year; −0.31±0.06% per year) were seen for non-users compared with baseline (p<0.001). A significant increase in mean BMD was seen for users compared with baseline (+1.86±0.0% per year, p<0.0018). TBS of users also increased compared with baseline (+0.20±0.08% per year, p<0.001), but more slowly than BMD. Conclusion: We observed a significant increase in spine BMD and a positive maintenance of bone micro-architecture from TBS with antiresorptive treatment, whereas the treatment naïve group lost both density and micro-architecture. TBS seems to be responsive to treatment and could be suitable for monitoring micro-architecture. This article is part of a Special Issue entitled ECTS 2011. Disclosure of interest: M.-A.

Targeting burn prevention in the pediatric population : a prospective study of children's burns in the Lausanne area

Rapport de synthèse : But de l'étude : Les accidents domestiques représentent un problème significatif en médecine pédiatrique. Le but de cette étude est de mieux comprendre les mécanismes et causes des brûlures afin de pouvoir cibler la prévention. Méthode : Il s'agit d'une étude prospective d'une durée d'une année, d'Août 2004 à Août 2005. Les patients ayant consulté pour des brûlures à l'Hôpital de l'Enfance de Lausanne (HEL) ou au CHUV ont été répertoriés. Le mécanisme et les circonstances des brûlures ont été analysées, de même que l'environnement et les données psycho-sociales. Résultats : huitante-neuf patients ont été inclus dans l'étude, âgés de 2 mois à 15 ans. Septante-huit pour cent des patients avaient moins de 5 ans. Plus de la moitié étaient des garçons. Les brûlures par échaudement prédominaient. Nous n'avons pas pu mettre en évidence d'incidence augmentée de brûlures chez des patients de familles immigrées ou de niveau social bas. Dans la majorité des cas, un adulte était présent au moment de l'accident. Conclusion : Si l'on devait établir un profil type de l'enfant à risque de se brûler dans notre région, il s'agirait d'un garçon âgé de 15 mois-5ans, se brûlant en se versant une tasse de liquide chaud sur la main, à son domicile, en présence de l'un ou de ses deux parents. Le message de prévention devrait donc s'adresser directement aux parents, toutes nationalités et niveau social confondus afin de leur expliquer les dangers de brûlures présents au quotidien à leur domicile. A chaque contrôle, les pédiatres devraient parler des accidents domestiques aux parents. En insistant sur les dangers que représentent les tasses de café, la porte du four et la plaque de la cuisinière, qui sont des éléments du quotidien et qui méritent une attention à chaque utilisation. Les brûlures chez le petit enfant pourraient ainsi être fortement réduites.

Refractory status epilepticus: A prospective observational study.

Summary Purpose: Status epilepticus (SE) that is resistant to two antiepileptic compounds is defined as refractory status epilepticus (RSE). In the few available retrospective studies, estimated RSE frequency is between 31% and 43% of patients presenting an SE episode; almost all seem to require a coma induction for treatment. We prospectively assessed RSE frequency, clinical predictors, and outcome in a tertiary clinical setting. Methods: Over 2 years we collected 128 consecutives SE episodes (118 patients) in adults. Clinical data and their relationship to outcome (mortality and return to baseline clinical conditions) were analyzed. Results: Twenty-nine of 128 SE episodes (22.6%) were refractory to first- and second-line antiepileptic treatments. Severity of consciousness impairment and de novo episodes were independent predictors of RSE. RSE showed a worse outcome than non-RSE (39% vs. 11% for mortality; 21% vs. 63% for return to baseline clinical conditions). Only 12 patients with RSE (41%) required coma induction for treatment. Discussion: This prospective study identifies clinical factors predicting the onset of SE refractoriness. RSE appears to be less frequent than previously reported in retrospective studies; furthermore, most RSE episodes were treated outside the intensive care unit (ICU). Nonetheless, we confirm that RSE is characterized by high mortality and morbidity.

Results from a prospective, randomized, controlled study evaluating the acceptability and effects of routine pre-IVF counselling.

BACKGROUND: The aim of this study was to evaluate a model of routine pre-IVF counselling focusing on the narrative capacities of couples. The acceptability of counselling, the effects on emotional factors and the participants' assessments were considered. METHODS: The study included 141 consecutive childless couples preparing for their first IVF. Randomization was carried out through sealed envelopes attributing participants to counselled and non-counselled groups and was accepted by 100 couples. Another 12 couples refused randomization because they wanted counselling and 29 because they did not. Questionnaires including the State-Trait Anxiety Inventory, the Beck Depression Inventory and assessments of help were mailed to couples before IVF and counselling, and after the IVF outcome. RESULTS: Counselling was accepted by 79% (112/141) of couples. There was no significant effect of counselling on anxiety and depression scores which were within normal ranges at both times. Counselling provided help for 86% (75/87) of initially non-demanding subjects and 96% (25/26) of those initially requesting a session. Help was noted in areas of psychological assistance, technical explanations and discussing relationships. CONCLUSIONS: This model of routine counselling centred on the narrative provides an acceptable form of psychological assistance for pre-IVF couples.

Issue review : IPERS retirement dividend payments.

The Iowa Public Employees' Retirement System, or IPERS, does not apply a traditional cost-of-living adjustment for retirement benefits. A retiree's monthly benefit payment is determined by a formula at the time of retirement and the amount does not change. Instead of adjusting the monthly benefit for inflation, the General Assembly creates two separate once-a-year payments for retirees, the November dividend for pre-1990 retirees and the favorable experience dividend, or FED for 1990 and later retirees. Available funding for the FED is estimated to be depleted within the next three years.

Intravenous pamidronate as treatment for osteoporosis after heart transplantation: a prospective study.

Fractures due to osteoporosis are one of the major complications after heart transplantation, occurring mostly during the first 6 months after the graft, with an incidence ranging from 18% to 50% for vertebral fractures. Bone mineral density (BMD) decreases dramatically following the graft, at trabecular sites as well as cortical sites. This is explained by the relatively high doses of glucocorticoids used during the months following the graft, and by a long-term increase of bone turnover which is probably due to cyclosporine. There is some evidence for a beneficial effect on BMD of antiresorptive treatments after heart transplantation. The aim of this study was to assess prospectively the effect on BMD of a 3-year treatment of quarterly infusions of 60 mg of pamidronate, combined with 1 g calcium and 1000 U vitamin D per day, in osteoporotic heart transplant recipients, and that of a treatment with calcium and vitamin D in heart transplant recipients with no osteoporosis. BMD of the lumbar spine and the femoral neck was measured by dual-energy X-ray absorptiometry in all patients every 6 months for 2 years and after 3 years. Seventeen patients, (1 woman, 16 men) aged 46+/-4 years (mean +/- SEM) received only calcium and vitamin D. A significant decrease in BMD was observed after 6 months following the graft, at the lumbar spine (- 6.6%) as well as at the femoral neck (-7.8%). After 2 years, BMD tended to recover at the lumbar spine, whereas the loss persisted after 3 years at the femoral neck. Eleven patients (1 woman and 10 men) aged 46+/-4 years (mean +/- SEM) started treatment with pamidronate on average 6 months after the graft, because they had osteoporosis of the lumbar spine and/or femoral neck (BMD T-score below -2.5 SD). Over the whole treatment period, a continuous increase in BMD at the lumbar spine was noticed, reaching 18.3% after 3 years (14.3% compared with the BMD at the time of the graft). BMD at the femoral neck was lowered in the first year by -3.4%, but recovered totally after 3 years of treatment. In conclusion, a 3-year study of treatment with pamidronate given every 3 months to patients with existing osteoporosis led to a significant increase in lumbar spine BMD and prevented loss at the femoral neck. However, since some of these patients were treated up to 14 months after the transplant, they may already have passed through the phase of most rapid bone loss. In patients who were not osteoporotic at baseline, treatment with calcium and vitamin D alone was not able to prevent the rapid bone loss that occurs immediately after transplantation.

Stress ulcer prophylaxis in non-critically ill patients: a prospective evaluation of the practice in a surgical ward

Introduction The benefit of stress ulcer prophylaxis (SUP) in noncriticallyill patients has not been proved. Over-prescription of SUP isnot devoided of risks (i.e. drug-drug interactions, adverse events).This prospective study aimed to evaluate the use of proton pumpinhibitors (PPIs) for SUP in a visceral surgery ward.Materials & Methods Data collection was performed prospectivelyduring a 8-week period on patients hospitalized in a visceral surgeryward (58 beds). Patients with a PPI prescription for the treatment ofulcers, gastroesophageal reflux disease, esophagitis or epigastralgiawere excluded as well as patients hospitalized twice during the studyperiod. The American Society of Health-System Pharmacists guidelineson SUP were used to assess the appropriateness of de novo PPIprescriptions.Results Among 255 patients in the study, 138 (54.1%) received aprophylaxis with PPI, of which 86 (62.3%) were de novo PPI prescriptions.93.5% of patients received esomeprazole (according to thehospital drug formulary) mainly orally at 40 mg qd. 79.1% of patientshad no risk factors for SUP. 17.9% and 3.0% had one and two riskfactors, respectively. 95% of the patients with PPI were not hospitalizedin the intensive care unit (ICU) before their stay in the visceralsurgery ward. At discharge, PPI therapy was continued in 34.2% ofpatients with a de novo PPI prescription.Discussion & Conclusion This study highlights the over-utilizationof PPIs in non-ICU patients and the inappropriate continuation of PPIprescriptions at discharge. The PPI dosage prescribed for prophylaxiswas probably too high compared with the data of the literature.Treatment recommendations for SUP are needed to restrict PPIuse for justified indications.

SWIVIT - Swiss video-intubation trial evaluating video-laryngoscopes in a simulated difficult airway scenario: study protocol for a multicenter prospective randomized controlled trial in Switzerland.

BACKGROUND: Video-laryngoscopes are marketed for intubation in difficult airway management. They provide a better view of the larynx and may facilitate tracheal intubation, but there is no adequately powered study comparing different types of video-laryngoscopes in a difficult airway scenario or in a simulated difficult airway situation. METHODS/DESIGN: The objective of this trial is to evaluate and to compare the clinical performance of three video-laryngoscopes with a guiding channel for intubation (Airtraq?, A. P. Advance?, King Vision?) and three video-laryngoscopes without an integrated tracheal tube guidance (C-MAC?, GlideScope?, McGrath?) in a simulated difficult airway situation in surgical patients. The working hypothesis is that each video-laryngoscope provides at least a 90% first intubation success rate (lower limit of the 95% confidence interval >0.9). It is a prospective, patient-blinded, multicenter, randomized controlled trial in 720 patients who are scheduled for elective surgery under general anesthesia, requiring tracheal intubation at one of the three participating hospitals. A difficult airway will be created using an extrication collar and taping the patients' head on the operating table to substantially reduce mouth opening and to minimize neck movement. Tracheal intubation will be performed with the help of one of the six devices according to randomization. Insertion success, time necessary for intubation, Cormack-Lehane grade and percentage of glottic opening (POGO) score at laryngoscopy, optimization maneuvers required to aid tracheal intubation, adverse events and technical problems will be recorded. Primary outcome is intubation success at first attempt. DISCUSSION: We will simulate the difficult airway and evaluate different video-laryngoscopes in this highly realistic and clinically challenging scenario, independently from manufacturers of the devices. Because of the sufficiently powered multicenter design this study will deliver important and cutting-edge results that will help clinicians decide which device to use for intubation of the expected and unexpected difficult airway. TRIAL REGISTRATION: NCT01692535.

Etude prospective d'évaluation psychiatrique et pédagogique dans un service pour adolescents de la Fondation Santé des Etudiants de France. Méthodologie et résultats préliminaires [Prospective study of psychiatric and pedagogic evaluation of the adolescent service of the Student Health Foundation of France. Methodology and preliminary results].

The present prospective study, with a five-year follow-up, presents an extensive psychiatric and educational assessment of an adolescent population (N = 30) in the age range 14-20, suffering from several psychiatric disorders, though apt to follow a normal academic program. The residential settings where the study took place provide both psychiatric and schooling facilities. In this environment, what is the effectiveness of long-term hospitalization? Are there any criteria for predicting results? After discharge, could social adjustments difficulties be prevented? Assessment instruments are described and the results of one preliminary study are presented. The actual data seems to confirm the impact of the special treatment facilities combining schooling and psychiatric settings on the long term outcome of adolescents.

Passive smoking exposure in adults and dynamics of respiratory symptoms in a prospective multicenter cohort studies (SAPALDIA study)

Résumé Objectifs : Alors que de nombreuses études suggèrent que l'exposition au tabagisme passif représente un danger pour la santé des non-fumeurs, la plupart des études s'intéressant aux effets néfastes du tabagisme passif sur la santé respiratoire de sujets adultes étaient des études transversales. Les résultats d'études longitudinales restent rares et controversés. Le but de notre étude était de mesurer les effets d'une exposition antérieure au tabagisme passif sur l'évolution journalière de quatre catégories de symptômes respiratoires dans une étude journalière incluant des adultes n'ayant jamais fumé. Méthodes : Dans le cadre de l'étude SAPALDIA (Swiss study on air pollution and lung diseases in adults), nous avons mené une étude de cohorte prospective et multicentrique. 1421 adultes n'ayant jamais fumé étaient suivis durant deux ans sur la base de questionnaires journaliers remplis durant une à six périodes de quatre semaines répartis sur deux années (1992-1993). Nous avons ensuite déterminé le risque relatif (RR) de développer ou de s'amender de symptômes respiratoires en association avec une exposition antérieure au tabagisme passif. Résultats : Dans un échantillon d'adultes n'ayant jamais fumé, nous avons trouvé une association entre une exposition antérieure au tabagisme passif et une évolution péjorée de tous les symptômes respiratoires étudiés, montrant un risque relatif de 1.09 à 1.21 de développer les symptômes respiratoires, et un risque relatif de 0.91 à 0.83 de s'amender de ces symptômes. Une exposition au tabagisme passif sur la place de travail était associée à une diminution de la durée des intervalles libres sans symptômes bronchitiques (RR 1.33) et asthmatiques (RR 1.27), alors qu'une exposition uniquement en-dehors de la place de travail était associée avec un allongement de la durée des épisodes avec symptômes respiratoires des voies aériennes hautes ou basses (RR 0.78-0.77). Conclusion : Nos résultats suggèrent que l'exposition au tabagisme passif a des effets néfastes sur la dynamique journalière symptômes respiratoires, et que l'importance et le type d'effet sont influencés par le lieu d'exposition.

Neonatal herpes simplex virus infections in Switzerland: results of a 6-year national prospective surveillance study.

A large variation in neonatal herpes incidence is observed in USA and Europe. Better knowledge of neonatal herpes epidemiology is important to inform local prevention strategies. Between 2002 and 2008, the Swiss Paediatric Surveillance Unit reported prospectively proven neonatal herpes simplex virus infections. During the study period seven cases were declared, for an incidence of 1.6/100,000 (95% CI 0.64-3.28/100,000) live births. This is one of the lowest incidences of neonatal herpes reported.

Exclusion of pulmonary embolism using C-reactive protein and D-dimer. A prospective comparison.

Our goal was to evaluate the diagnostic utility of C-reactive protein (CRP) alone or combined with clinical probability assessment in patients with suspected pulmonary embolism (PE), and to compare its performance to a D-dimer assay. We conducted a prospective study in which we performed a common immuno-turbidimetric CRP test and a rapid enzyme-linked immunosorbent assay (ELISA) D-dimer test in 259 consecutive outpatients with suspected PE at the emergency department of a teaching hospital. We assessed clinical probability of PE by a validated prediction rule overridden by clinical judgment. Patients with D-dimer levels &gt; or = 500 microg/l underwent a work-up consisting of lower-limb venous ultrasound, spiral computerized tomography, ventilation-perfusion scan, or pulmonary angiography. Patients were followed up for three months. Seventy-seven (30%) of the patients had PE. The CRP alone had a sensitivity of 84% (95% confidence interval [CI).: 74 to 92%) and a negative predictive value (NPV) of 87% (95% CI: 78 to 93%) at a cutpoint of 5 mg/l. Overall, 61 (24%) patients with a low clinical probability of PE had a CRP &lt; 5 mg/l. Due to the low prevalence of PE (9%) in this subgroup, the NPV increased to 97% (95% CI: 89 to 100%). The D-dimer (cutpoint 500 micro g/l) showed a sensitivity of 100% (95% CI: 95 to 100%) and a NPV of 100% (95% CI: 94 to 100%) irrespective of clinical probability and accurately rule out PE in 56 (22%) patients. Standard CRP tests alone or combined with clinical probability assessment cannot safely exclude PE.
