Infliximab for pediatric ulcerative colitis: a retrospective Italian multicenter study.
2008
Abstract Background Infliximab (IFX), the chimeric anti TNFalpha antibody, an established treatment for Crohn's disease in adults and in children, is used less frequently in ulcerative colitis (UC). Aim of the study To report the clinical course of pediatric patients with active UC receiving IFX. Patients and methods Charts of 22 patients were reviewed (13 male, 9 female): 4 with a severe UC attack refractory to systemic corticosteroids (CS); 18 with a protracted course, of which 16 CS-dependent and 2 CS-resistant. The baseline therapeutic program consisted of 3 consecutive intravenous infusions (0, 2, 6 weeks) of IFX (5 mg/kg), followed by a retreatment schedule (infusion every 8 weeks); a…
International, multicenter evaluation of a new D-dimer assay for the exclusion of venous thromboembolism using standard and age-adjusted cut-offs.
2017
We sought to determine the test characteristics of an automated INNOVANCE D-dimer assay for the exclusion of pulmonary embolism (PE) and deep venous thrombosis (DVT) in emergency department (ED) patients using standard and age-adjusted cut-offs.Cross-sectional, international, multicenter study of consecutive patients with suspected DVT or PE in 24 centers (18 USA, 6 Europe). Evaluated patients had low or intermediate Wells PE or DVT scores. For the standard cut-off, a D-dimer result500 ng/ml was negative. For the age adjusted cut-off, we used the formula: Age (years) ∗ 10. The diagnostic standard was imaging demonstrating PE or DVT within 3 months. We calculated test characteristics using s…
Cardiopulmonary Hemodynamic Profile Predicts Mortality After Transcatheter Tricuspid Valve Repair in Chronic Heart Failure.
2020
This study was designed to assess hemodynamic changes in response to transcatheter tricuspid valve edge-to-edge repair (TTVR) and to identify hemodynamic predictors associated with mortality.Severe tricuspid regurgitation (TR) is associated with high mortality. TTVR effectively alleviates heart failure symptoms, but comprehensive hemodynamic characterization of patients undergoing TTVR is currently lacking.This international, multicenter study included 236 patients undergoing TTVR. Data from clinical assessment, echocardiography, intraprocedural right heart catheterization, and noninvasive cardiac output measurement were analyzed. Hemodynamic predictors for mortality were identified using l…
Deflazacort vs. prednisone in Duchenne muscular dystrophy: trends of an ongoing study
1995
Several studies have demonstrated the slowing effect of corticosteroids on the decline of muscle strength in Duchenne muscular dystrophy (DMD). Deflazacort (DFC) is supposed to have fewer side effects than prednisone (PRED). An ongoing double blind multicenter study is comparing the effects and side effects of deflazacort (0.9 mg/kg/day) and prednisone (0.75 mg/kg/day) in DMD. This interim report includes data for 67 boys between age 5 years and loss of ambulation. Besides the common clinical and laboratory data for chronic corticoid treatment, motor performance has been tested. Interim results, 3-15 months after starting the medication, show some scattering but no grouping of data for all …
Frequency of Renal Dysfunction and Frailty in Patients ≥80 Years of Age With Acute Coronary Syndromes.
2019
While a significant association between renal function and outcomes in patients with acute coronary syndromes (ACS) has been consistently described, little information exists about the magnitude of this association in patients at older ages. No study assessed the prognostic role of renal function according to frailty in patients with ACS. The LONGEVO-SCA registry included unselected ACS patients aged≥80 years. Frailty was asessesed by the FRAIL scale, and baseline creatinine clearance was calculated by the Cockroff-Gault formula. We evaluated the impact of renal function on mortality or readmission at 6-months according to frailty status by the Cox regression method. A total of 473 patients…
Clinical Inertia in Poorly Controlled Elderly Hypertensive Patients: A Cross-Sectional Study in Spanish Physicians to Ascertain Reasons for Not Inten…
2013
Clinical inertia, the failure of physicians to initiate or intensify therapy when indicated, is a major problem in the management of hypertension and may be more prevalent in elderly patients. Overcoming clinical inertia requires understanding its causes and evaluating certain factors, particularly those related to physicians.The objective of our study was to determine the rate of clinical inertia and the physician-reported reasons for it.An observational, cross-sectional, multi-center study was carried out in a primary care setting. We included 512 physicians, with a consecutive sampling of 1,499 hypertensive patients with clinical inertia.Clinical inertia was defined when physicians did n…
Primary Radical Prostatectomy or Ablative Radiotherapy as Protective Factors for Patients With mCRPC Treated With Radium-223 Dichloride: An Italian M…
2020
Abstract Background We investigated, in a real-life setting, the prognostic relevance of previous primary treatment (radical prostatectomy [RP] or external beam radiotherapy [EBRT]) on overall survival for patients with metastatic castration-resistant prostate cancer (mCRPC) treated with radium-223 (223Ra). Materials and Methods In the present multicenter retrospective study, we enrolled 275 consecutive patients. The demographic and clinical data and mCRPC characteristics were recorded and evaluated at baseline and at the end of treatment or progression. 223Ra was administered according to the current label authorization until disease progression or unacceptable toxicity. We divided the who…
Analysis of Inappropriate Admissions of Residents of Medicalized Nursing Homes to Emergency Departments: A Prospective Multicenter Study in Burgundy
2016
Abstract Objectives To determine the rate of inappropriate admissions to emergency departments (EDs) and to identify determinants of these admissions. Design Prospective multicenter study. Setting Burgundy (France), EDs and medical nursing homes (MNHs). Participants 1000 Burgundy MNH residents admitted to EDs, from April 17 to June 20, 2013. Measurements For each subject, a questionnaire was completed. Data included age, gender, type of health professional who referred the resident to the ED (THP), whether or not a medical dispatcher organized the transfer to the ED, transport mode, reason for admission to the ED, level of independence according to the Groupes Iso-Ressource score (GIRS), an…

Diagnostic accuracy of computed tomographic colonography for the detection of advanced neoplasia in individuals at increased risk of colorectal cance…
2009
CONTEXT: Computed tomographic (CT) colonography has been recognized as an alternative for colorectal cancer (CRC) screening in average-risk individuals, but less information is available on its performance in individuals at increased risk of CRC. OBJECTIVE: To assess the accuracy of CT colonography in detecting advanced colorectal neoplasia in asymptomatic individuals at increased risk of CRC using unblinded colonoscopy as the reference standard. DESIGN, SETTING, AND PARTICIPANTS: This was a multicenter, cross-sectional study. Individuals at increased risk of CRC due to either family history of advanced neoplasia in first-degree relatives, personal history of colorectal adenomas, or positiv…
