Gonadotropin and Testosterone Secretion in Normal Human Males After Stimulation With Gonadotropin-Releasing Hormone (Gnrh) or Potent Gnrh Analogs Usi…

1978

Gonadotropin-releasing hormone (GnRH) and some potent long-acting GnRH analogs, applied by different routes of administration, were tested in six healthy human males. The effects on gonadotropin secretion were compared with the one after intravenous (i.v.) bolus injection of 25 microgram of GnRH. The net increase of luteinizing hormone (deltaLH) in serum produced by 25 microgram of GnRH i.v. was matched by subcutaneous (s.c.) injection of 100 microgram of GnRH, dissolved in 20% gelatin or without gelatin; 5 microgram of D-Ser (TBU)6-des-Gly10-GnRH-ethylamide i.v.; 5 microgram of D-Leu6-des-Gly10-GnRH-ethylamide i.v.; and 50 microgram of D-Trp6-des Gly10-GnRH-ethylamide given pernasally (p.n…

Hearing loss in Fabry disease: data from the Fabry Outcome Survey

2006

Hearing loss is a common symptom in Fabry disease, but neither its natural course nor its aetiology has been defined precisely. The aim of this study was to provide a detailed epidemiological description of hearing impairment in patients in the Fabry Outcome Survey (FOS), which is the largest available database of Fabry patients. Questionnaires were completed by 566 Fabry patients, of whom 316 reported ear-related symptoms. Pure-tone audiograms from 86 patients, performed before starting enzyme replacement therapy, were analysed and compared with age- and sex-specific normal values (International Organization for Standardization, ISO 7029). When compared to an age-matched population (ISO 70…

Evaluation of the Possible Impact of a Care Network for Stroke and Transient Ischemic Attack on Rates of Recurrence

2010

We aimed to demonstrate that a stroke network is able to reduce the proportion of recurrent cerebrovascular events. In 2003, we set up a care network with the aim to reduce the proportion of stroke recurrence. For the statistical analysis, recurrent cerebrovascular events observed from 1985 to 2002 within the population of Dijon made it possible to model trends using Poisson logistic regression. From 1985 to 2002, we recorded 172 recurrent cerebrovascular events which were used to model trends before the creation of the care network. Within the period 2003–2007, we observed 162 recurrent cerebrovascular events compared with 196.7 expected cerebrovascular events with a significant standardiz…

Auditory Mismatch Negativity and Repetition Suppression Deficits in Schizophrenia Explained by Irregular Computation of Prediction Error

2015

Background The predictive coding model is rapidly gaining attention in schizophrenia research. It posits the neuronal computation of residual variance (‘prediction error’) between sensory information and top-down expectation through multiple hierarchical levels. Event-related potentials (ERP) reflect cortical processing stages that are increasingly interpreted in the light of the predictive coding hypothesis. Both mismatch negativity (MMN) and repetition suppression (RS) measures are considered a prediction error correlates based on error detection and error minimization, respectively. Methods Twenty-five schizophrenia patients and 25 healthy controls completed auditory tasks designed to el…

Nomograms including nuclear matrix protein 22 for prediction of disease recurrence and progression in patients with Ta, T1 or CIS transitional cell c…

2005

ABSTRACT Purpose: We developed and validated nomograms that accurately predict disease recurrence and progression in patients with Ta, T1, or CIS transitional cell carcinoma (TCC) of the bladder using a large international cohort. Methods: Univariate and multivariate logistic regression models targeted histologically confirmed disease recurrence, and focused on 2,542 patients with bladder TCC from 10 participating centers. Variables consisted of pre-cystoscopy voided urine Nuclear Matrix Protein 22 (NMP22) assay, urine cytology, age and gender. Resulting nomograms were internally validated with bootstrapping. Nomogram performance was explored graphically with Loess smoothing plots. Results:…

Immunization Campaigns and Strategies against Human Papillomavirus in Italy: The Results of a Survey to Regional and Local Health Units Representativ…

2019

Objective. The study aimed to assess the impact of HPV immunization campaigns organizational aspects, the characteristics of immunization program (vaccination targets and type of offer), and communicative strategies adopted by four Italian administrative regions on vaccination coverage observed. Methods. From November 2017 to March 2018, regional and Local Health Units (LHUs) representatives were invited to complete an online survey including 54 questions evaluating vaccination invite systems, access systems to vaccination centres, reminder and recall systems, and adverse events surveillance. An overall descriptive analysis was conducted. Since observed vaccine coverage (VC) obtained in fem…

Two-stage multi-Gaussian fitting of conduit artery photoplethysmography waveform during induced unilateral hemodynamic events.

2014

Photoplethysmography (PPG) is an optical technique with high diagnostic potential, yet clinical applications remain underdeveloped. Standardization of signal recording and quantification of waveform are essential prerequisites for broader clinical use. The aim of this study was to utilize a two-stage multi-Gaussian fitting technique in order to examine the parameters of conduit artery PPG waveform recorded during increasing the unilateral regional vascular resistance (RVR). This study was conducted on 14 young and healthy volunteers; various external compressions (ECs) were performed by inflating a tight cuff at 0, 40, 80, and 200 mmHg, while registering femoral PPG (wavelength 880 nm), dia…

Integrating Downstaging in the Risk Assessment of Patients With Locally Advanced Rectal Cancer Treated With Neoadjuvant Chemoradiotherapy: Validation…

2017

Abstract Background Adjuvant chemotherapy is controversial in patients with locally advanced rectal cancer after preoperative chemoradiation. Valentini et al developed 3 nomograms (VN) to predict outcomes in these patients. The neoadjuvant rectal score (NAR) was developed after VN to predict survival. We aimed to validate these tools in a retrospective cohort at an academic institution. Patients and Methods VN and the NAR were applied to 158 consecutive patients with locally advanced rectal cancer treated with chemoradiation followed by surgery. According to the score, they were divided into low, intermediate, or high risk of relapse or death. For statistical analysis, we performed Kaplan-M…

Improving Quality of Care in Inflammatory Bowel Disease Through Patients’ Eyes: IQCARO Project

2019

Abstract Background Quality improvement is a major topic in inflammatory bowel disease (IBD) care, and measuring quality of care (QoC) is necessary for QoC improvement. Most QoC projects or consensus statements are designed from the health care professional point of view. Having QoC indicators designed for and fully evaluable by patients may provide a key tool for external evaluation of QoC improvement measures. The aim of the IQCARO project was to identify indicators to measure QoC from the IBD patient’s point of view. Methods An extensive review of the literature to identify indicators of QoC was performed; first the identified indicators were reviewed by a steering committee including pa…
