A case-control study on risk factors for nuclear, cortical and posterior subcapsular cataract: The Casteldaccia Eye Study
2005
Purpose: To investigate risk factors for nuclear, cortical and posterior subcapsular age-related cataract. Methods: A case-control study was carried out on subjects aged 40 years and older, living in Casteldaccia, Sicily. Twenty-seven potential risk factors were investigated. Nuclear, cortical and posterior subcapsular opacities of the lens were classified according to the Lens Opacities Classification System II. Subjects with advanced lens opacities represented the cases, while an identical number of subjects without or with early cataract, matched for sex and age, were recruited as controls from within the same population. Results: Univariate analysis showed that myopia and iris atrophy w…

Stiffness Estimation and Adaptive Control for Soft Robots
2022
Nonostante la sorprendente crescita nello sviluppo dei robot ispirati alla natura, tra cui i cosiddetti soft robot, il potenziale di questi sistemi, che hanno intrinseche capacità di adattamento, non è ancora stato sfruttato a pieno. La ricerca ha principalmente considerato il controllo in retroazione della posizione dei giunti del robot, lasciando la gestione della cedevolezza di questi ultimi ancora in anello aperto. Peraltro, le attuali limitazioni nel processo di produzione degli attuatori a cedevolezza variabile e l'inevitabile variabilità nel tempo degli elementi elastici costitutivi, i quali sono soggetti ad usura e deformazione plastica, rendono il problema della determinazione prec…

A sustainable city environment through child safety and mobility:A challenge based on ITS?
2012
Our cities should be designed to accommodate everybody, including children. We will not move toward a more sustainable society unless we accept that children are people with transportation needs, and ‘bussing’ them around, or providing parental limousine services at all times, will not lead to sustainability. Rather, we will need to make our cities walkable for children, at least those above a certain age. Safety has two main aspects, traffic safety and personal safety (risk of assault). Besides being safe, children will also need an urban environment with reasonable mobility, where they themselves can reach destinations with reasonable effort; else they will still need to be driven. This p…
Forensic Analysis of Fire in a Substation of a Commercial Center
2020
In this article, the authors discuss the legal liabilities of the professional engineer as both the engineer of record of a project and the construction site manager. In particular, this article analyzes the case of a fire at the end-user medium voltage–low-voltage (MV–LV) substation of a shopping center in Italy, which occurred a few years after the maintenance works on the electrical installation. The professional engineer who had designed and overseen the construction of the substation was accused of professional negligence. The authors through the examination of applicable technical standards, as well as of safety regulations, demonstrate that the professional engineer had acted diligen…
Safety and immunogenicity of the therapeutic vaccine TG1050 in chronic hepatitis B patients: a phase 1b placebo-controlled trial
2020
Funding: Transgène; International audience; Treatment of chronic hepatitis B (CHB) typically requires life-long administration of drugs. Cohort and pre-clinical studies have established the link between a functional T-cell-mounted immunity and resolution of infection. TG1050 is an adenovirus 5-based vaccine that expresses HBV polymerase and domains of core and surface antigen and has shown immunogenicity and antiviral effects in mice. We performed a phase 1 clinical trial to assess safety and explore immunogenicity and early efficacy of TG1050 in CHB patients. This randomized, double blind, placebo-controlled study included two sequential phases: one single dose cohort (SD, n = 12) and one …
Systematic review and meta-analysis of the efficacy and safety of minocycline in schizophrenia
2017
ObjectiveOur aim was to perform an updated systematic review and meta-analysis on the efficacy and safety of adjunctive minocycline as a treatment of schizophrenia.MethodsWe conducted a PubMed/Scopus database search from inception to 3 February 2016 for randomized, placebo-controlled trials (RCTs), open non-randomized studies, and case reports/series evaluating minocycline in patients with schizophrenia. Random-effects meta-analysis of positive, negative, depressive, and cognitive symptom rating scales, discontinuation and adverse effects rates calculating standardized mean difference (SMD), and risk ratios±95% confidence intervals (CI95%) were calculated.ResultsSix RCTs were eligible (mino…
A methodological look at the controversy about the influence of salt intake on cardiovascular risk
2012
Cardiovascular diseases are a major cause of premature death and disability. They represent an extraordinarily strong financial burden upon health-care systems in ‘‘developed’’ countries. Elevated blood pressure is a major cause of cardiovascular disease. There is much evidence that cardiovascular risk increases from normal blood pressure (i.e., from 115/75 mmHg upwards) [1]. Overwhelming evidence shows that reducing salt intake from 9–12 g/day to 5–6 g/day lowers blood pressure [2]. Blood pressure is a surrogate endpoint, but may be related to a reduction of morbidity and mortality due to cardiovascular causes. Thus, intensive support and encouragement to cut down on the intake of salt in …
Current situation and historical evolution of the study and research of blackflies (Diptera: Simuliidae) in Spain. A tale of bleeding bites
2019
The black flies are nematocerous dipterans belonging to the Simuliidae family. This group of insects has become highly relevant in certain regions of the country since 1995. These insects, considered typical in natural lotic environments of clean fresh water, have colonized water channels of very different dimensions. They are currently present in most of the water courses around the country, as demonstrated in the Valencian Autonomous Region, where they can be found in headwaters, middle stretches and river mouths, as well as in irrigation systems with greater or lesser water permanence, such as irrigation reservoirs, channels and ditches. Since 2017 different regions of the country have i…
