Remodeling of Cortical Structural Networks in Multiple Sclerosis
2019
Multiple sclerosis (MS) is one of the most frequent immune-mediated disorders of the central nervous system. Pathological events occurring within the white matter and gray matter compartments can be reliably tracked in vivo by magnetic resonance imaging (MRI) but conventional imaging parameters do not reflect the remodeling processes of the brain. Here, we sought to investigate the reorganization of cortical structural networks in a group of patients with MS. For this, 40 patients (mean age ± standard deviation 31.2 ± 7.0 years, 14 males) with relapsing-remitting MS and 40 healthy subjects (27.1 ± 5.0 years, 14 males) were included in the study. From T1-weighted MR image-derived cortical th…
A Systematic Review of Cost-effectiveness Evidence of Endoscopic Saphenous Vein Harvesting: Is it Efficient?
2011
Objective: Greater saphenous vein harvest for coronary and lower extremity bypass requires the longest incision of any surgical procedure. Endoscopic vein harvest allows better results in some clinical variables compared to open harvesting techniques. The objec- tive of this study is to present the results of a systematic review of the scientific evidence about the efficiency of endoscopic saphenous vein harvest. Methods: We performed a systematic review in the bibliographical databases Pubmed, National Health Service Economic Evaluation Database, and NHS Health Technology Assess- ment Database. The search strategy was "endoscopic AND harvesting", in the period January 1970eDecember 2009. R…
Day care cataract surgery in Central and Southern Italy: a multicentric survey
2007
Abstract Background Cataract day surgery has rapidly gained worldwide acceptance, because the new surgical techniques and costs are generally lower than those involved in ordinary hospitalization. Cataract surgery serves as a proxy indicator of the trend towards day surgery hospitalization in Italy and, therefore, of regional variability in health-care delivery and cost. The aim of this study was to update the diffusion of cataract day surgery through various surgical ophthalmological centers in central and southern Italy during 2005. Methods A two-stage stratified cluster sampling method was used to draw a sample of Cataract Surgery Unit from Ophthalmic Units of central and southern Italy.…

Efficiency of telemedicine for acute stroke: a cost-effectiveness analysis from a French pilot study
2020
AbstractObjectivesTelestroke is an effective way to improve care and health outcomes for stroke patients. This study evaluates the cost-effectiveness of a French telestroke network.MethodsA decision analysis model was built using population-based data. We compared short-term clinical outcomes and costs for the management of acute ischemic stroke patients before and after the implementation of a telestroke network from the point of view of the national health insurance system. Three effectiveness endpoints were used: hospital death, death at 3 months, and severe disability 3 months after stroke (assessed with the modified Rankin scale). Most clinical and economic parameters were estimated fr…
Inhibition of growth of measles virus by mycoplasma in cell-cultures and the restoring effect of arginine
1970
Presence of mycoplasma in MK cell cultures caused an inhibition of measles virus, as revealed by a lower plating efficiency. When arginine is supplemented to the cell-system, mycoplasma contaminated cells yield plaque titers as high as those of uncontaminated cells. The essential role of arginine for plaque formation of measles virus is suggested also by experiments in which arginine added to the agar overlay restored the plating efficiency of measles virus in cultures maintained in a minimal nutrient medium.
Inspiratory and Lower-Limb Strength Importance in Mountain Ultramarathon Running. Sex Differences and Relationship with Performance
2020
The study was aimed at comparing lower-limb strength and respiratory parameters between male and female athletes and their interaction with performance in a 107 km mountain ultramarathon. Forty seven runners (29 males and 18 females
The association between quality of care and technical efficiency in long-term care
2005
To analyse the association between quality of care and technical (productive) efficiency in institutional long-term care wards for the elderly.One hundred and fourteen public health centre hospitals and residential homes in Finland.Wards were divided into two categories according to their rank in the quality distribution, considering 41 quality variables separately. The technical efficiency scores of the good- and poor-quality groups were compared using cross-sectional data.Data envelopment analysis was used for calculating technical efficiency. The Mann-Whitney test and correlation coefficients were used to explore the association between quality and efficiency.The wards where quality indi…
Effects of Transcranial Direct Current Stimulation on Baseline and Slope of Prefrontal Cortex Hemodynamics During a Spatial Working Memory Task
2020
Background: Transcranial direct current stimulation (tDCS) has been shown to be an inexpensive, safe, and effective way of augmenting a variety of cognitive abilities. Relatively recent advances in neuroimaging technology have provided the ability to measure brain activity concurrently during active brain stimulation rather than after stimulation. The effects on brain activity elicited by tDCS during active tDCS reported by initial studies have been somewhat conflicted and seemingly dependent on whether a behavioral improvement was observed. Objective: The current study set out to address questions regarding behavioral change, within and between-participant designs as well as differentiatin…
Prévenir et réduire les risques de sélection de résistances : de la théorie à la pratique, des pistes pour améliorer la durabilité des PPP
2015
SPEPôle GEAPSICT2communication orale invitée, résumé; La résistance est le résultat inéluctable de la sélection exercée par les PPP sur les populations de bio-agresseurs. On ne peut pas empêcher une résistance d’évoluer, mais on peut retarder substantiellement son évolution en mettant en place des stratégies appropriées avant (prévention) et après (gestion) la détection des premiers individus résistants. Le point-clef à retenir pour cela est que plus le contrôle d’un bio-agresseur est basé sur une chimie peu diversifiée, plus le risque de sélectionner rapidement une résistance est élevé. Un exemple type de ce qu’il ne faut pas faire est de contrôler un bio-agresseur présent sur de grandes s…
