Usage and Dose Response of a Mobile Acceptance and Commitment Therapy App: Secondary Analysis of the Intervention Arm of a Randomized Controlled Trial
2016
Background: Mobile phone apps offer a promising medium to deliver psychological interventions. A mobile app based on Acceptance and Commitment Therapy (ACT) was developed and studied in a randomized controlled trial (RCT). Objective: To study usage metrics of a mobile ACT intervention and dose-response relationship between usage and improvement in psychological flexibility. Methods: An RCT was conducted to investigate the effectiveness of different lifestyle interventions for overweight people with psychological stress. This paper presents a secondary analysis of the group that received an 8-week mobile ACT intervention. Most of the analyzed 74 participants were female (n=64, 86%). Their me…

Network of international scientific collaboration on smoking: analysis of coauthorship through the Science Citation Index (1999-2003)
2009
Objetivo: El objetivo de este trabajo fue establecer los patrones de colaboración científica internacional y la visibilidad que genera la coautoría de artículos sobre tabaquismo en relación a países, a través del Science Citation Index-Expanded (SCI-Expanded) en el periodo de 1999 a 2003. Material y métodos: Se seleccionaron los artículos de colaboración sobre tabaquismo entre países en SCI-Expanded (1999-2003). Se analizaron las redes de colaboración subyacente entre países, comparando su productividad (número de artículos producidos), su visibilidad (número de citas recibidas) y centralidad (grado nodal, intermediación y proximidad). Resultados: Se recuperaron 3.484 artículos en los que h…

An immunohistochemical study of the distribution of p 16 protein in oral mucosa in smokers, non-smokers and in frictional keratosis
2009
Objective: Our study aimed to characterize alteration in the immunohistochemical p16 expression in normal oral mucosa and non-neoplastic hyperproliferative disorders (i.e. frictional keratosis and mucosa from smokers). Study design: 43 specimen of oral mucosa were examined using immunohistochemistry. Results: In normal mucosa, there was strong positive nuclear staining in a proportion of fibroblasts and endothelial cells in the lamina propria, with variable expression in nuclei of the epithelial layer. However, when the patient?s tobacco smoking was examined, p16 nuclear staining in oral epithelium was seen in 4/20 (20%) of smokers and 0/23 (0%) of non-smokers. In every case of frictional k…
Accuracy of cotinine serum test to detect the smoking habit and its association with periodontal disease in a multicenter study
2016
Background The validity of the surveys on self-reported smoking status is often questioned because smokers underestimate cigarette use and deny the habit. It has been suggested that self-report should be accompanied by cotinine test. This report evaluates the usefulness of serum cotinine test to assess the association between smoking and periodontal status in a study with a large sample population to be used in studies with other serum markers in epidemiologic and periodontal medicine researches. Material and Methods 578 patients who were part of a multicenter study on blood biomarkers were evaluated about smoking and its relation to periodontal disease. Severity of periodontal disease was …
Smoking, health and ageing.
2008
Abstract On March 19, 2008 a Symposium on Pathophysiology of Ageing and Age-Related diseases was held in Palermo, Italy. Here, the lecture of V. Nicita-Mauro on Smoking, health and ageing is summarized. Smoking represents an important ageing accelerator, both directly by triggering ana inflammatory responses, and indirectly by favoring the occurrence of several diseases where smoking is a recognized risk factor. Hence, non-smokers can delay the appearance of diseases and of ageing process, so attaining longevity.
Epidemiology of intensive care unit-acquired sepsis in Italy: Results of the SPIN-UTI network
2018
Background. Sepsis is the major cause of mortality from any infectious disease worldwide. Sepsis may be the result of a healthcare associated infection (HAI): the most frequent adverse events during care delivery especially in Intensive Care Units (ICUs). The main aim of the present study was to describe the epidemiology of ICU-acquired sepsis and related outcomes among patients enrolled in the framework of the Italian Nosocomial Infections Surveillance in ICUs - SPIN-UTI project. Study design. Prospective multicenter study. Methods. The SPIN-UTI network adopted the European protocols for patient-based HAI surveillance. Results. During the five editions of the SPIN-UTI project, from 2008 to…
In vitro contamination of hair by marijuana smoke.
2004
Abstract Background: The deposition of cannabinoids on/into hair from environmental smoke can be considered as a potential source of drug findings in hair. We studied external uptake of cannabinoids from marijuana smoke, investigating possible influencing factors on drug uptake and the efficiency of decontamination procedures. Methods: Strands of a natural hair sample were moistened with water, greased with sebum or sebum/sweat, or bleached or permed. Treated and untreated samples were exposed to marijuana smoke for 60 min. Aliquots of each hair strand were either kept unwashed or were washed with methanol, dichloromethane, or 5 g/L dodecyl sulfate in water. Cannabinoid concentrations in un…
Monitoring of the smoking process by multicommutation Fourier Transform Infrared spectroscopy
2007
Abstract Nicotine was selected as the target molecule for monitoring of the smoking process by multicommutation Fourier Transform Infrared spectroscopy (FTIR). The method involved the use of CHCl3 for on-line extraction of nicotine from tobacco, cigarette filters and tobacco ash from NH4OH alkalinized samples, and absorbance measurement of the characteristic band at 1316 cm−1 in the stopped-flow mode, by obtaining the peak area in the range between 1334 and 1300 cm−1. Under the best operational conditions, the procedure developed provided a detection limit of 0.05 mg mL−1 nicotine, corresponding to 0.5 mg g−1 in the solid sample, a relative standard deviation less than 2.5%, and a sampling …
