Towards an automatic lab-on-valve-ion mobility spectrometric system for detection of cocaine abuse.
2017
A lab-on-valve miniaturized system integrating on-line disposable micro-solid phase extraction has been interfaced with ion mobility spectrometry for the accurate and sensitive determination of cocaine and ecgonine methyl ester in oral fluids. The method is based on the automatic loading of 500μL of oral fluid along with the retention of target analytes and matrix clean-up by mixed-mode cationic/reversed-phase solid phase beads, followed by elution with 100μL of 2-propanol containing (3% v/v) ammonia, which are online injected into the IMS. The sorptive particles are automatically discarded after every individual assay inasmuch as the sorptive capacity of the sorbent material is proven to b…
An investigation of the stability of free and glucuronidated 11-nor-delta9-tetrahydrocannabinol-9-carboxylic acid in authentic urine samples.
2004
Preanalytical stability of a drug and its major metabolites is an important consideration in pharmacokinetic studies or whenever the analyte pattern is used to estimate drug habits. Firstly, the stability of free and glucuronidated 11-nor-delta9-tetrahydrocannabinol-9-carboxylic acid (THCCOOH, THCCOOglu) in authentic urine samples was investigated. Random urine samples of cannabis users (n = 38) were stored at -20, 4, and 20 degrees C up to 15 days and up to 5 days at 40 degrees C, and alterations of the analyte pattern during storage were followed by liquid chromatography-tandem mass spectrometry. Secondly, the influence of pH (range 5.0-8.0) on the stability of the analytes was studied us…
Meet–Test–Treat for HCV management: patients’ and clinicians’ preferences in hospital and drug addiction services in Italy
2022
Abstract Background It has been estimated that the incidence of chronic hepatitis C virus (HCV) will not decline over the next 10 years despite the improved efficacy of antiviral therapy because most patients remain undiagnosed and/or untreated. This study aimed to investigate the opinion of relevant target populations on the practicability, effectiveness and best modalities of the test-and-treat approach in the fight against HCV in Italy. Methods A survey was delivered to patients with HCV from the general population, patients from drug addiction services, hospital physicians and healthcare providers for drug addiction services. Results For both hospital clinicians and SerD HCPs, tolerabil…
Effects of a brief pre‑admission telephone reminder on no‑show and dropout rates in substance use disorder treatment: a quasi‑experimental study
2022
Abstract Background Appointment no-show and early dropout from treatment represent major challenges in outpatient substance use disorder treatment, adversely affecting clinical outcomes and health care productivity. In this quasi-experimental study, we examined how a brief reminder intervention for new patients before their first appointment affected treatment participation and retention. No-shows (not attending any sessions) and dropouts (discontinuation of initiated treatment because of three consecutively missed appointments) were compared between a period with pre-admission telephone calls (intervention) and a period without such reminders (non-intervention). Methods Participants were a…
Association between passive tobacco exposure and caries in children and adolescents. A systematic review and meta-analysis.
2017
To examine the available evidence on the association between exposure to tobacco use in the womb and in infancy and the presence of caries in primary and permanent dentition in children and adolescents. A systematic review was conducted through searches in 4 data bases (Pubmed, Scopus, Embase and Web of Science), complemented by hand-searching. Of the 559 articles identified, 400 were duplicates. Finally, 28 articles were included in the qualitative review and 21 in the meta-analysis. Their quality was assessed using the Newcastle-Ottawa scale. The quality was medium in 44% of the articles included and high in 56%. The overall meta-analysis gave a significant odds ratio (OR = 1.53, 95% conf…
Psychopathological Issues of Technological Addiction: New Diagnostic Criteria for Addiction.
2009
All forms of addiction (drug addiction, food addiction, sexual addiction, technological addiction, work addiction) are syndromic conditions characterized by a recurrent and reiterated search for pleasure derived from a specific dependence behavior, associated with abuse, craving, clinically significant stress, and compulsive dependence actions despite the possible negative consequences. The purpose of this article is to propose a new diagnostic criteria of addiction.

Defining substance use disorders: do we really need more than heavy use?
2013
Aims: The aim of the study was to explore whether the concept of heavy substance use over time can be used as definition of substance use disorder. Methods: Narrative review. Results: Heavy use over time clearly underlies the neurobiological changes asso- ciated with current thinking of substance use disorders. In addition, there is evidence that heavy use over time can explain the majority of social problems and of burden of disease (morbidity and mortality). A definition of substance use disorders via heavy use over time would avoid some of the problems of current conceptualizations, for instance the cultural specificity of concepts such as loss of control. Finally, stressing the continuu…
Immune regulatory neural stem/precursor cells protect from central nervous system autoimmunity by restraining dendritic cell function.
2009
Background: The systemic injection of neural stem/precursor cells (NPCs) provides remarkable amelioration of the clinicopathological features of experimental autoimmune encephalomyelitis (EAE). This is dependent on the capacity of transplanted NPCs to engage concurrent mechanisms of action within specific microenvironments in vivo. Among a wide range of therapeutic actions alternative to cell replacement, neuroprotective and immune modulatory capacities of transplanted NPCs have been described. However, lacking is a detailed understanding of the mechanisms by which NPCs exert their therapeutic plasticity. This study was designed to identify the first candidate that exemplifies and sustains …
