Six years of spreading BLSD skills in schools: empowering teachers as trainers.

Introduction: To increase the population's ability to handle emergencies, life-saving maneuvers should be universally acquired as an automatic skill starting from school through frequent and practical retraining. Teachers could be ideal multipliers, but it is necessary to design pathways that train and motivate them, since Basic Life Support and Defibrillation (BLSD) skills are not part of their academic curricula. This study explores innovative training solutions and facilitating factors to enhance BLSD education in schools by focusing on the training and motivation of teachers.

Female Reproductive Health and Exposure to Phthalates and Bisphenol A: A Cross Sectional Study.

The xenoestrogenicity of some plasticisers (phthalates and bisphenol A) is documented in the literature and may pose a risk to female reproductive health. The aim of this study was to assess exposure to six phthalates. This was achieved by measuring their respective metabolites (mono-ethylphthalate (MEP); mono-n-butylphthalate (MnBP); mono-n-ottylphthalate (MnOP); and monobenzylphthalate (MBzP)), as well as the sum of two of the diethyl-hexyl phthalate metabolites-(∑DEHP) and bisphenol A (BPA) in a female population with infertility problems, and by conducting a correlation analysis between infertility factors, work activities, and lifestyle habits, in order to formulate a causal hypothesis.

Teaching Life-Saving Manoeuvres in Primary School.

In the event of sudden cardiac arrest (SCA) early intervention provided by a layperson can be life-saving. Teaching first aid in primary school may increase the lifelong ability and motivation of young people to take action in an emergency. The aim of this article is to report a training experience on BLSD (Basic Life Support and Defibrillation) designed for a group of pupils in an Italian primary school, with assessment of its effectiveness at a distance.

[DIFFERENT APPROACHES FOR CHEMICAL RISK ASSESSMENT IN LABORATORIES].

The aim of this study was to compare the different approaches used for chemical risk assessment, in relation to the perception of riskfor operators, in some research laboratories of a hospital in Rome. All information regarding the chemicals used for the application of three algorithmic models for chemical risk assessment ("Movarisch", "Inforisk", "Archimede") were collected. An environmental and biological monitoring and a study on the combined exposure to multiple chemicals using the World Health Organization proposed steps were carried out.

Urinary metabolite concentrations of phthalate metabolites in Central Italy healthy volunteers determined by a validated HPLC/MS/MS analytical method.

The main objective of this study was to determine the average concentrations for the metabolites of the four more common phthalates, industrial chemicals widely used in commercial products and potential endocrine disruptors, in the urine of a control population living in Central Italy. The study population consisted of 157 healthy subjects, not occupationally exposed to phthalates (74 males and 83 females). Urinary levels of the analytes were determined by liquid chromatography tandem mass spectrometry (LC-MS/MS) with isotopic dilution.

Urinary phthalate monoesters concentration in couples with infertility problems.

The widespread use of phthalates results in human exposure: phthalates are rapidly metabolized to their respective monoesters and other oxidative products, which are glucuronidated and excreted through the urine and feces. Several in vivo studies showed that some phthalates, in particular diethyl-hexyl phthalate (DEHP), diethyl phthalate (DEP), di(n-butyl)phthalate (DnBP) and n-butylbenzylphthalate (BBzP), are able to interact with the human endocrine system, interfering with the reproduction ability. In this study, 56 couples were recruited from a centre of assisted reproduction.

Exposure to styrene in fiberglass-reinforced plastic manufacture: still a problem.

Objective: The aim of the work is to define occupational exposure to styrene in fiberglass manufacture; the phase of stretching styrene resins needs some manual handling and leads workers to be exposed to styrene.

Methods: We surveyed 20 workers in two companies manufacturing fiberglass, checking environmental levels and urinary concentrations of mandelic acid (MA), and phenylglioxylic acid (PGA). Workers completed a questionnaire collecting their medical history.

Complete separation of urinary metabolites of xylene in HPLC/DAD using β-cyclodextrin: application for biological monitoring.

To determine the biomarkers of exposure to xylene, urinary 2-, 3- and 4-methyl-hippuric acids, a new HPLC/DAD analytical method has been developed, which uses β-cyclodextrin as an additive for elution; its complexing abilities are exploited to achieve complete chromatographic separation of the three isomers. The mobile phase was a 3% aqueous solution of β-cyclodextrin, pH 3, and methanol, 80:20, in isocratic conditions, with a flow rate of 1 mL/min. To optimize quantitative analysis three wavelengths were employed for detection: λ=198 nm, λ=200 nm, and λ=202 nm.
