The QRS narrowing index for easy and early identification of responder to cardiac resynchronization therapy.
2013
The rationale for cardiac resynchronization therapy (CRT) in patients with heart failure (HF) is based on the possibility of inducing substantial left ventricular reverse remodeling. It is well known that some of these patients don't benefit from this therapy (the so-called non-responders) [1,2]. No better predictors of a positive answer to CRT than pre-CRT QRS duration (QRSd) were found [3,4]. The aim of our study was to identify a parameter for an easy and early identification of responders to CRT. In this regard, according to Rickard et al., we identified and observed QRS index (QI), as an expression of electrical remodeling after CRT, and its relation with anatomic reverse remodeling, e…
Predictors of long-term outcomes in patients undergoing periodontal maintenance
2017
Abstract Aim This retrospective study aimed to characterize the baseline status of patients following periodontal maintenance, analysing the association between the long‐term outcome of these patients, smoking, bruxism, and the main clinical and radiographic variables. Material and methods A sample of 174 patients with moderate to severe periodontitis was refined into homogeneous subsamples according to smoking and bruxism and the rate of tooth loss due to periodontal disease (TLPD): 0, 1–2, and >2 teeth. The association and the distribution (χ² test) of the variables within the subsamples were analysed. Results Smoking and bruxism were significantly associated with higher TLPD rates. Verti…
Colonoscopic screening of first-degree relatives of patients with large adenomas: increased risk of colorectal tumors.
2007
International audience; Background & Aims: The risk of developing colorectal neoplasia is not well established among family members of individuals with large adenomas and screening strategies remain under debate in this population. This study aimed at quantifying the risk of colorectal adenomas and cancers using colonoscopic screening in first-degree relatives of patients with large adenomas. Methods: This case-control study was performed in 18 endoscopic units of French non-University Hospitals. A colonoscopy was offered to first-degree relatives of 306 index cases with adenomas ≥ 10 mm, if they were alive, aged 40-75 and could be contacted by the index case. Among 674 relatives meeting th…
Good clinical response, remission, and predictors of remission in rheumatoid arthritis patients treated with tumor necrosis factor-α blockers: The GI…
2007
OBJECTIVE: To assess the prevalence of good clinical response and remission in rheumatoid arthritis (RA) patients with longstanding disease treated with anti-tumor necrosis factor-alpha (TNF-alpha) drugs at outpatient clinics. METHODS: Retrospective national study of 14 academic tertiary referral rheumatology medical centers. RA patients with a Disease Activity Score (DAS28) > 3.2 were defined as having active disease and could start TNF-alpha blockers. All patients received one TNF-alpha blocker plus methotrexate (10-20 mg/wk). At the third month the patients were categorized as responders or nonresponders, based on improvement of at least 0.25 of the Health Assessment Questionnaire (HAQ).…
