The Communicative-Relational Operating Model of the Italian National Institute of Health for an Effective Telephone Intervention in Public Health, Structured on Basic Counselling Skills.

Introduction: Communication has a crucial role in public health, because it becomes an essential component of prevention; it is also a proactive tool in health promotion. From a planning perspective, it is appropriate to use communication means that can help the bidirectional communication process, such as face-to-face communication and telephone communication. Materials and methods: In relation to this, the Italian National Institute of Health has developed the "Modello Operativo Comunicativo-Relazionale" (the "Communicative-Relational Operating Model"). It is based on the fundamental skills of the counselling, this gives a protocol to the health professionals that is replicable and organized and it allows health professionals to carry out a telephone communication that is efficient with the user through technical-scientific and communication-relational skills. The goal is to answer in a customized way to the various users' health needs. The Operating Model was created by experts of the National AIDS and Sexually Transmitted Infections Helpline of the Operational Unit of Psycho-Socio-Behavioural Research, Communication, Training, of the Infectious Diseases Department. Later, the Operating Model was proposed to the experts of the Helplines in the National Centre on Addictions and Doping and the National Helpline of the National Centre for Rare Diseases in the National Institute of Health that integrated this method into their telephone approach. Results: The Operating Model illustrated above was applied to several helplines of the National Institute of Health as an example of correct scientific information, updated and customized on sexual transmitted infections, addictions and rare diseases. Conclusions: This article aims to illustrate the Operating Model, the theoretical prerequisites that subtend it and its possible application in the different public health structures that use the telephone for a profes-sional relationship with their users.

Hepatotoxicity associated with illicit use of anabolic androgenic steroids in doping.

Anabolic Androgenic Steroids (AAS) abuse and misuse is nowadays a harmful habit involving both professional or recreational athletes, as well as general population. AAS are also frequently present in over-the-counter dietary supplements without being declared in the list of ingredients, leaving consumers unaware of the risks of adverse effects. Indeed, health risks of AAS consumption in pharmaceutical preparations or dietary complements seem still underestimated and under-reported. The variety of complications due to AAS misuse involves cardiovascular, central nervous, musculoskeletal and genitourinary systems of both males and females; psychiatric and behavioral effects, damages to metabolic system, skin and mainly liver. For instance, relevant concern has been raised by the AAS hepatotoxicity including adenoma, hepatocellular carcinoma, cholestasis, and peliosis hepatis. The present review reports the information available on the hepatotoxic effects of AAS use in professional and amateur athletes.

"Vehicular homicide", a new Italian offence: law provisions and comparison with some other European countries.

According to the most recent World Health Organization report, road accidents represent a very serious public health issue, claiming each year more than 1.2 million lives worldwide and being the leading cause of death among young people aged between 15 and 29 years. Up to now, the policies to reduce this issue are different, unbalanced and often inadequate not only in Italy, but also in the other European Countries. Specifically, the Italian Parliament has recently introduced a new law (n. 41 of March 23rd, 2016), making vehicular homicide together with road traffic injuries a criminal offense, both to be punished as a result of negligence. The measure came into force on March 25th, 2016. In this paper, the provisions of the above-reported law have been assessed, taking into account the modifications introduced in the Penal Code by this law and the impact it is having and will have on drivers on a day-to-day basis. Similarities and differences with legislative framework of some other European countries were also examined. Finally, some open questions to be solved are named as an open eye for future considerations.

Which group of smokers is more vulnerable to the economic crisis?

OBJECTIVES: Studies investigating whether smoking increases or decreases during economic downturn provided contrasting results. For the first time, we used direct questions to analyse changes in smoking behaviour due to the 2008 financial crisis, comparing socio-economic characteristics of smokers who changed with those who kept their smoking intensity. STUDY DESIGN: Cross-sectional survey. METHODS: We used data from three annual surveys conducted in Italy in 2012-2014 on representative samples of the Italian general population aged ≥15 years. RESULTS: A total of 1919 current smokers were asked specific questions on the influence of the economic crisis that started in 2008 on their smoking behaviour. Overall, 77.4% of 1919 current smokers reported not to have changed their smoking behaviour, 19.1% to have reduced, and 3.5% to have increased their smoking intensity as a consequence of the economic crisis. The reduction in cigarette smoking increased with age: compared to the respondents aged <25 years, the multivariate odds ratio (OR) for those aged 25-44, 45-64 and ≥65 years were 0.65, 0.46 and 0.33, respectively (P for trend<0.001). Reduction was significantly lower among intermediate (OR = 0.68 compared to low) and high education levels (OR = 0.28; P for trend<0.001). A significant inverse trend for increasing consumption was observed with age (P = 0.022), education (P = 0.003) and family income (P < 0.001). CONCLUSIONS: The large majority of current smokers did not change their smoking habit following the economic crisis. However, there are specific vulnerable subgroups of smokers, constituted by the young and subjects with low socio-economic status, that were reactive to the global economic crisis. These groups are more prone to change their smoking behaviours, either for better or -, in a smaller proportion -, for worse.

Osteoimmunology and its implications for transplantation.

Osteoimmunology is a field of research dedicated to the study of the interactions between the immune system, the hemopoietic system and bone. Among the cells of the immune system that regulate bone cells and the hemopoietic function are T lymphocytes. These cells secrete inflammatory cytokines that promote bone resorption, as well as Wnt ligands that stimulate bone formation. In addition, T cells regulate bone homeostasis by cross talking with BM stromal cells and osteoblastic cells via CD40 ligand (CD40L) and other costimulatory molecules. This article describes the immune cells relevant to bone and the hemopoietic function, reviews the role of lymphocytes as mediators of the effects of PTH and estrogen in bone and the hemopoietic system and discusses the implication of osteoimmunology for transplant medicine.

Determination of maternal-fetal biomarkers of prenatal exposure to ethanol: a review.

The deleterious effects exerted by prenatal ethanol exposure include physical, mental, behavioural and/or learning disabilities that are included in the term fetal alcohol spectrum disorder (FASD). Objective assessment of exposure to ethanol at both prenatal and postnatal stages is essential for early prevention and intervention. Since pregnant women tend to underreport alcohol drinking by questionnaires, a number of biological markers have been proposed and evaluated for their capability to highlight gestational drinking behaviour. These biomarkers include classical biomarkers (albeit indirect) of alcohol-induced pathology (mean corpuscular volume (MCV), gamma glutamyltransferase (GGT), aspartate aminotransferase (AST) and alanine aminotransferase (ALT)) acetaldehyde-derived conjugates, and finally derivatives of non-oxidative ethanol metabolism (fatty acid ethyl esters (FAEEs), ethyl glucuronide (EtG), ethyl sulphate (EtS) and phosphaditylethanol (PEth)). Since ethanol itself and acetaldehyde are only measured few hours after ethanol intake in conventional matrices such as blood, urine and sweat, they are only useful to detect recent ethanol exposure. In the past few years, the non-oxidative ethanol metabolites have received increasing attention because of their specificity and in some case wide time-window of detection in non-conventional matrices from the pregnant mother (oral fluid and hair) and fetus-newborn (neonatal hair, meconium, placenta and umbilical cord). This article reviews bioanalytical procedures for the determination of these markers of ethanol consumption during pregnancy and related prenatal exposure. In addition, clinical toxicological applications of these procedures are presented and discussed.

A survey of Italian and Spanish neonatologists and paediatricians regarding awareness of the diagnosis of FAS and FASD and maternal ethanol use during pregnancy.

BACKGROUND: Ethanol is the most widely used drug in the world and a human teratogen whose consumption among women of childbearing age has been steadily increasing. There are no Italian or Spanish statistics on ethanol consumption during pregnancy nor any information regarding prevalence of fetal alcohol syndrome (FAS) and fetal alcohol spectrum disorders (FASD). There is also a reasonable suspicion that these two diseases are underdiagnosed by professionals from the above-reported countries. The objectives of this study were: 1) to evaluate the experience, knowledge and confidence of Italian and Spanish neonatologists and paediatricians with respect to the diagnosis of FAS and FASD, and 2) to evaluate professionals awareness of maternal drinking patterns during pregnancy. METHODS: A multiple-choice anonymous questionnaire was e-mailed to Italian neonatologists registered in the mailing list of the corresponding Society and administered to Italian and Spanish paediatricians during their National Congress. RESULTS: The response rate was 16% (63/400) for the Italian neonatologists of the National Society while a total of 152 Spanish and 41 Italian paediatricians agreed to complete the questionnaire during National Congress. Over 90% of the surveyed physicians declared that FAS is an identifiable syndrome and over 60% of them identified at least one of the most important features of FAS. Although over 60% Italian responders and around 80% Spanish responders were aware that ethanol use in pregnancy is dangerous, approximately 50% Italian responders and 40% Spanish ones allowed women to drink sometimes a glass of wine or beer during pregnancy.Neonatologists and paediatricians rated confidence in the ability to diagnosis FAS and FASD as low, with over 50% responders feeling they needed more information regarding FAS and FASD identification in newborn and child. CONCLUSIONS: Italian and Spanish neonatologists and paediatricians do not feel confident about diagnosing FAS and FASD. More training is needed in order to accurately diagnose ethanol use during pregnancy and correctly inform pregnant women on the consequences on the newborn.

Pharmacokinetics of methylphenidate in oral fluid and sweat of a pediatric subject.

Methylphenidate (MPH) is a stimulant medication widely used for treating attention-deficit hyperactivity disorder (ADHD) in children and adolescents. Therapeutic monitoring for this drug is essentially lacking and alternative biological matrices, such as oral fluid and sweat, should be investigated for noninvasive assessment of short- and long-term history of drug use. We report the excretion profile of MHP and its metabolite ritalinic acid (RA) in oral fluid and sweat from a 12-year-old boy treated with the extended release drug formulation. Concentrations of MPH and RA in oral fluid, sweat and plasma were measured by liquid chromatography-mass spectrometry. Oral fluid-to-plasma ratio at each time interval was calculated at the start of the treatment and correlated with salivary pH. Excretion of MPH in sweat patches, collected up to 24h with PharmChek patches was also investigated. MPH and RA were both detected in oral fluid with a pharmacokinetic profile similar to that in plasma. Oral fluid peak concentrations of MPH ranged between 13.5 and 30.9 ng/mL at 3.0 h after drug intake. Oral fluid-to-plasma MPH ratio between 13.1 and 3.2 demonstrated an accumulation of the drug in oral fluid. Conversely, RA was found in oral fluid at peak concentration (23.4-62.9 ng/mL) equivalent to one-tenth of those found in plasma. Concentration profiles of MPH and RA in oral fluid were quite constant during the four weeks of drug administration. In sweat, MPH was detected for the first time at 5h after drug administration (range: 9.3-11.2 ng/patch) up to 24h (range: 29.8-38.7 ng/patch). RA was not detected in the sweat patches during the 24h time of collection. The results suggest that measurement of MPH in oral fluid can be used as a potential alternative to drug monitoring in plasma. Moreover, MPH measurement in sweat patches can be used for noninvasive monitoring of MPH consumption and misuse in situations where detection of recent abuse is of interest.

Assessment of exposure to environmental tobacco smoke in young adolescents following implementation of smoke-free policy in Italy.

We investigated acute and chronic exposure to environmental tobacco smoke (ETS) in a cohort of young adolescents using urinary cotinine and hair nicotine testing after recent implementation of Italian smoke free legislation. Study subjects were 372 Italian young adolescents, between 10 and 16 years of age from the principal city of Sicily, Palermo. Urine and hair samples were collected between November 2005 and May 2006, when the legislation to ban smoking in all the enclosed places of employment (including bars, restaurants, pubs) was completely enforced. An exhaustive questionnaire including sociodemographic characteristics and active and passive exposure to cigarette smoking was completed. Urinary cotinine was analyzed by radioimmunoassay and hair nicotine by a validated GC/MS method. Based on urinary cotinine results, 2.1% and 89% of the study participants, respectively, showed non-exposure and low acute exposure to ETS, whereas only 1.6% presented very high exposure or a hidden active smoking habit in the recent past. Hair nicotine disclosed non-exposure and low exposure to ETS in 11.8% and 65.6% of the young adolescents, respectively, taking into consideration a larger time-window. High repeated exposure, suggesting active smoking in some cases was observed in 8.6% of the study subjects. Hair nicotine was inversely related to educational level of the adolescents' parents. Overall, due to the implementation of smoke-free legislation and information campaign against smoking, a significant trend toward low exposure to ETS was observed in this study cohort with no association between exposure to ETS and respiratory illnesses.

[Prenatal exposure to drugs of abuse using meconium analysis in a low socioeconomic population in Barcelona]. / Exposición prenatal a drogas de abuso a través del análisis de meconio en una población de bajo nivel socioeconómico en Barcelona.

INTRODUCTION: For the first time in Europe, the <> aimed to estimate the prevalence of drug use by pregnant women and the subsequent foetal exposure to illicit drugs. PATIENTS AND METHOD: Between October 2002 and February 2004, 1209 mother-infant dyads from the Hospital del Mar, Barcelona, Spain met eligibility criteria and agreed to participate in the study. Data on socio-economic and demographic characteristics and on drug habits during pregnancy were collected using a structured questionnaire. Neonatal meconium was collected within 24h after birth and analyzed by standardized chromatographic techniques for the presence of opiates, cocaine, cannabinoids and amphetamines. RESULTS: Meconium analysis showed an overall 10.9% positivity for drugs of abuse, with a specific prevalence of heroin, cocaine and cannabis with foetal exposure of 4.7, 2.6 and 5.3%, respectively. Structured interviews also revealed that 0.3, 1.2 and 1.5% of mothers used heroin, cocaine and cannabis, respectively, while only one mother declared ecstasy consumption, confirmed by meconium analysis. Parental ethnicity and working class was not associated with drug use. Drug consuming mothers were shown to have a higher number of previous abortions when compared to non-consumer mothers, which was probably due to a lack of family planning. Significantly lower birth weight and length was found in newborns from mothers exposed to cocaine alone or in combination with other drugs. CONCLUSIONS: This study, although developed in a low socio-economic-status cohort, may serve as an eye opener for any hidden non-negligible drug consumption during pregnancy. In this sense, meconium analysis can be important to identify neonates with a high suspicion of exposure to drugs of abuse in utero, and provides the basis for appropriate treatment and adequate medical and social follow-up.

Exposición prenatal a drogas de abuso a través del análisis de meconio en una población de bajo nivel socioeconómico en Barcelona / Prenatal exposure to drugs of abuse using meconium analysis in a low socioeconomic population in Barcelona

Introducción: por primera vez en Europa, el «Proyecto Meconio» ha estimado la prevalencia del consumo de drogas ilegales por mujeres embarazadas y la consiguiente exposición fetal. Pacientes y método: entre octubre de 2002 y febrero de 2004, se incluyó en el estudio a 1.209 parejas madre-recién nacido del Hospital del Mar, Barcelona. Se recogieron datos sobre las características socioeconómicas y demográficas y los hábitos tóxicos durante el embarazo empleando un cuestionario. Se recogió el meconio neonatal antes de 24 horas después del nacimiento y se analizó empleando técnicas cromatográficas estandarizadas para detectar opiáceos, cocaína, cannabinoides y anfetaminas. Resultados: el análisis del meconio demostró una positividad para las drogas de abuso del 10,9% del total, con una prevalencia específica de exposición fetal a heroína, cocaína y cannabis del 4,7, el 2,6 y el 5,3%, respectivamente. El cuestionario estructurado detectó que el 0,3, el 1,2 y el 1,5% de las madres habían consumido heroína, cocaína y cannabis, y sólo una madre declaró el consumo de éxtasis, confirmado mediante el análisis del meconio. La etnia de los padres y la clase laboral no se asociaron con el consumo de drogas. Las madres consumidoras de drogas mostraron un número de abortos previos más elevado que las madres no consumidoras. Se encontró que el peso y la talla al nacimiento eran significativamente más bajos en los recién nacidos de las madres expuestas a cocaína sola o en combinación con otras drogas. Conclusiones: este estudio puede servir como aviso de un consumo de drogas durante el embarazo oculto y significativo. En este sentido, el análisis del meconio puede ser importante para identificar a recién nacidos en elevada sospecha de exposición intrauterina a drogas de abuso y proporciona la base para un tratamiento médico y un seguimiento social apropiados (AU)

ORALVEQ: external quality assessment scheme of drugs of abuse in oral fluid: results obtained in the first round performed in 2007.

The Institut Municipal d'Investigació Mèdica IMIM-Hospital del Mar (Barcelona, Spain) in cooperation with the Istituto Superiore di Sanità (Rome, Italy) organized an external quality assessment scheme to assess the reliability of analytical laboratories when analyzing drugs of abuse in oral fluid (ORALVEQ). For the first round of ORALVEQ, performed in February 2007, three different samples (S1, S2 and S3) were sent to 21 participating international laboratories. S1 was a blank sample and S2 and S3 were prepared by addition of drugs at known concentrations to pre-screened drug-free oral fluid (containing sodium azide) and diluted up to 50% with acidic buffer. S2 contained 6-monoacetyl morphine, morphine, cocaine and benzoylecgonine and S3 contained 3,4-methylendioxymethamphetamine and 3,4-methylendioxyamphetamine. Results were evaluated from a qualitative and quantitative point of view. Whereas only half laboratories performed screening analysis, all of them reported a quantitative result for almost all analytes. Eighteen false-positive and 3 false-negative results were reported by 8 (from a total of 21) laboratories. The quantitative evaluation was performed measuring dispersion (% coefficient of variation, CV%) and accuracy (% error, ERR%) of results and calculating the z-score values (using robust statistics). ERR% between 2% and 20% and CVs% around 40% were obtained for all analytes. In terms of z-score, a high percentage of adequate results (between 85 and 95%) was obtained. In general, the participating laboratories had a satisfactory performance. The number of false-negatives reported was very low, the false-positives were reported by a reduced number of laboratories and the scatter in the quantitative results was principally due to a few outlying values; since applying robust statistics, there was no rejection of outliers.

On-site screening and GC-MS analysis of cocaine and heroin metabolites in body-packers urine.

The illicit transportation of cocaine and heroin either swallowed or inserted into the rectum and/or vagina of individuals, defined as "body-packers", is becoming increasingly common. Assessment of smuggling by urinalysis from body-packers has been sparsely reported and on-site rapid screening methods are essentially lacking. We screened the presence of cocaine and heroin metabolites in urine from suspected body-packers by an on-site immunochromatographic test and confirmed the obtained results by gas chromatography-mass spectrometry and X-ray examination. Samples were collected from 64 individuals (45 men, 19 women) stopped at Fiumicino and Ciampino airports of Rome (Italy) for suspicion of internal concealment of cocaine and heroin between October 2006 and July 2007. Urine was immediately screened on-site by Cozart rapid urine test. Irrespective of test results, individuals underwent X-ray examination and urine samples were analyzed by gas chromatography-mass spectrometry (GC-MS). In 48 out of 64 cases (24 positives and 24 negatives) screening results were confirmed by GC-MS assay and X-ray examination. In 5 cases, positive to the on-site test and GC-MS analysis, abdominal radiography was negative and individuals resulted to be drug users. In 11 cases, negative to the on-site test and radiological investigation, GC-MS analysis found benzoylecgonine in 10 cases and morphine in one case. Concentration of both substances was in all cases lower than 50ng/ml and compatible with personal drug use. From obtained results, on-site detection of cocaine and heroin metabolites in the urine of suspected body-packers appears to be a reliable screening test to disclose internally concealed drugs and justify subsequent radiological investigations.

Cognitive performance in recreational ecstasy polydrug users: a two-year follow-up study.

There is important preclinical evidence of long lasting neurotoxic and selective effects of ecstasy MDMA on serotonin systems in non-human primates. In humans long-term recreational use of ecstasy has been mainly associated with learning and memory impairments. The aim of the present study was to investigate the neuropsychological profile associated with ecstasy use within recreational polydrug users, and describe the cognitive changes related to maintained or variable ecstasy use along a two years period. We administered cognitive measures of attention, executive functions, memory and learning to three groups of participants: 37 current polydrug users with regular consumption of ecstasy and cannabis, 23 current cannabis users and 34 non-users free of illicit drugs. Four cognitive assessments were conducted during two years. At baseline, ecstasy polydrug users showed significantly poorer performance than cannabis users and non-drug using controls in a measure of semantic word fluency. When ecstasy users were classified according to lifetime use of ecstasy, the more severe users (more than 100 tablets) showed additional deficits on episodic memory. After two years ecstasy users showed persistent deficits on verbal fluency, working memory and processing speed. These findings should be interpreted with caution, since the possibility of premorbid group differences cannot be entirely excluded. Our findings support that ecstasy use, or ecstasy/cannabis synergic effects, are responsible for the sub-clinical deficits observed in ecstasy polydrug users, and provides additional evidence for long-term cognitive impairment owing to ecstasy consumption in the context of polydrug use.

HAIRVEQ 2006: evolution of laboratories' performance after different educational actions.

HAIRVEQ is a proficiency testing program for hair analysis of illicit drugs organized by the Istituto Superiore di Sanità (Rome, Italy) and the Institut Municipal d'Investigació Mèdica (Barcelona, Spain). The aim of the three exercises performed in 2006 was the evaluation of 32 laboratories' performance when analyzing the same hair sample containing opiates, cocaine and methadone, after carrying out some specific educational interventions. In the first round, the sample was sent to be analyzed following laboratory routine methodology. In the second round, standard operating procedures (SOP) for hair testing including sample preparation, method validation and qualitative and quantitative data evaluation, and an open hair sample for SOP training were also sent together with other hair samples including the one used for performance evaluation. After the second round, a workshop was held with participant laboratories to discuss methodological issues and interpretation of obtained results. An additional amount of open samples was distributed to the laboratories for implementing the SOPs. In the third round, the same unknown sample containing opiates, cocaine and methadone was resent for the final evaluation of laboratory performance. In the first round, 11 incorrect qualitative results (10 false negative and 1 false positive) were reported by seven laboratories (22%), in the second round, a reduction in the number of incorrect results was observed (4 false negatives and 1 false positive were reported by four laboratories, 13%) and in the third round, 5 false positives and 5 false negatives were reported by seven laboratories (22%). Concerning quantitative results, the scatter was similar between the three rounds and similar to the ones reported by other proficiency tests in hair analysis. More educational actions should be addressed to a group of laboratories, which did not yet show satisfying qualitative and quantitative results.
