PDs with high number of driving hours per day, miles driven per year, and low educational level should be subject to special educational programs to reduce and prevent obesity.

Objectives: The aim of this study was to investigate the prevalence of obesity, alcoholic beverage consumption, unhealthy alcohol use and sudden sleep onset at the wheel among Italian truck drivers. In addition to prevalence rates, this study also aimed at investigating potential predictors for sudden-onset sleepiness and obesity. Material and Methods: A sample of truck drivers was extracted from the database of the High Risk Professional Driver Study. Data concerning demographics, anthropometry, medical information and working conditions were collected using anonymous questionnaires. Logistic regression analyses were performed to assess the association of the reported body mass index (BMI), alcohol consumption and sudden sleep onset with working conditions and general lifestyle factors. Results: Three hundred and thirty-five questionnaires were collected. According to their BMI, 45% of the participants were overweight and 21.4% of them were obese. Twenty-four point two percent declared they drank alcoholic beverages during working hours or work breaks and 21.3% of the drivers had an Alcohol Use Disorders Identyfication Test Consumption (AUDIT C) score ≥ 5 (the threshold value for unhealthy alcohol use). Forty-one point six percent of the interviewees experienced one episode of sudden sleep onset at the wheel per month (5.5% per week and 0.9% daily). Predictive factors for obesity were: length of service (odds ratio (OR) = 1.09, confidence interval (95% CI): 1.04-1.15, p < 0.001) and the AUDIT C total score (OR = 1.34, 95% CI: 1.08-1.66, p = 0.008). Predictive factors for sudden-onset sleepiness at the wheel were: age > 55 years old (OR = 5.22, 95% CI: 1.29-21.1, p = 0.020), driving more than 50 000 km per year (OR = 2.89, 95% CI: 1.37-6.11, p = 0.006) and the Chalder Fatigue Questionnaire (CFQ) score > 11 (adjusted OR = 2.97, 95% CI: 1.22-7.21, p = 0.016). Conclusions: This study strongly emphasizes the need for intervention in order to reduce and prevent important risk factors for the sake of road safety and truck drivers' health.

Objectives: A high percentage of professional drivers (PDs) often report feeling fatigue during their work, and falling asleep at the wheel (FAW) is a major contributing factor to the occurrence of near-miss or actual accidents. The aim of this study is to evaluate the prevalence of FAW among Italian PDs and the effect of fatigue on this occurrence (corrected for the main predictive factors already known). Material and Methods: We performed a cross-sectional questionnaire survey. Data from PDs (N = 497) were used for analyses. Logistic regression analyses were performed to assess the association of reported sudden-onset sleep at the wheel with working conditions and general lifestyle factors. Results: Forty-one percent of the interviewees experienced at least 1 episode per month of sudden-onset sleep at the wheel (4.7% per week). Predictive factors of self-reported FAW were: age > 55 years old (odds ratio (OR) = 4.91, confidence interval (CI): 1.79-13.50, p < 0.01), traveling more than 40 thousand miles per year (OR = 1.86, 95% CI: 1.08-3.22, p < 0.05), body mass index ≥ 30 (OR = 2.16, 95% CI: 1.01-4.64, p < 0.05) and Chalder Fatigue Questionnaire score > 22 (OR = 3.93, 95% CI: 1.90-8.14, p < 0.01). Conclusions: There are different work and human factors underlying FAW among PDs. The Chalder Fatigue Questionnaire might be useful in measuring fatigue in this group and in detecting PDs at high risk of experiencing FAW.

Galectin-3 demonstrated to be a robust independent marker of cardiovascular mid-term (18-month) outcome in heart failure (HF) patients. The objective of this study was to analyze the value of a predischarged determination of plasma galectin-3 alone and with plasma brain natriuretic peptide (BNP) in predicting mid-term outcome in frequent-flyers (FF) HF (≥2 hospitalization for HF/year)/dead patients discharged after an acute decompensated HF (ADHF) episode.All FF chronic HF subjects discharged alive after an ADHF were enrolled. All patients underwent a determination of BNP and galectin-3, a 6-minute walk test, and an echocardiogram within 48 hours upon hospital discharge. Death by any cause, cardiac transplantation, and worsening HF requiring readmission to hospital were considered cardiovascular events.Eighty-three patients (67 males, age 73.2 ± 8.6 years old) were analyzed (mean follow-up 11.6 ± 5.2 months; range 4–22 months). During the follow-up 38 events (45.7%) were scheduled: (13 cardiac deaths, 35 rehospitalizations for ADHF). According to medical history, in 33 patients (39.8%) a definition of FF HF patients was performed (range 2–4 hospitalization/year). HF patients who suffered an event (FF or death) demonstrated more impaired ventricular function (P = 0.037), higher plasma BNP (P = 0.005), and Gal-3 at predischarge evaluation (P = 0.027). Choosing adequate cut-off points (BNP ≥ 500 pg/mL and Gal-3 ≥ 17.6 ng/mL), the Kaplan–Meier curves depicted the powerful stratification using BNP + Gal-3 in predicting clinical course at mid-term follow-up (log rank 5.65; P = 0.017).Adding Gal-3 to BNP, a single predischarge strategy testing seemed to obtain a satisfactorily predictive value in alive HF patients discharged after an ADHF episode.

In Italy, Workplace Drug Testing (WDT) has been compulsory by law for specific categories of workers since 2008, offering the opportunity to compare studies conducted within a single regulatory framework. The aims of this paper are to estimate the overall prevalence of WDT positivity (at screening survey) among Italian workers and evaluate the percentage of true and false positives at confirmation analysis. A systematic review and meta-analysis of the scientific literature on WDT in Italy from January 2008 to March 2015 was carried out, according to the MOOSE guidelines. A random effects model was utilized to calculate pooled prevalence. Potential sources of heterogeneity were explored using sensitivity test and subgroup analysis. The overall meta-analytical prevalence of positivity at WDT among Italian workers was 1.4% [95% confidence interval (CI) = 1.1-1.7%]. It was significantly lower among workers screened with an on-site test (1%; 95% CI = 0.5-1.5%), compared with a bench-top test (1.7%; 95% CI = 1.3-2.1%). Nine studies provided data on false positives at the screening test, with a combined prevalence estimate - calculated on positive cases - of 30% (95% CI = 16-44%). In Italy, the number of true positives at first-level workplace drug testing is low, while the frequency of false positives is relatively high. A revision of the Italian legislation on the subject seems advisable. Copyright © 2017 John Wiley & Sons, Ltd.
