Cancer incidence in a cohort of asbestos-exposed workers undergoing health surveillance.

OBJECTIVES: To compare a local cohort of 2488 men occupationally exposed to asbestos and enrolled in a public health surveillance program with the 1995-2009 cancer incidence of the general population of Friuli Venezia Giulia (FVG) region, Northeast Italy, we conducted a historical cohort study. METHODS: Standardized incidence ratios (SIRs), with 95% confidence interval (95% CI), for specific cancer sites were estimated in the cohort and in subgroups of workers employed in shipbuilding between 1974 and 1994. For internal comparisons, we calculated incidence rate ratios (IRRs) for all cancers, lung cancer and mesothelioma, by level of exposure to asbestos and sector of employment adjusted for smoking habits and age at start of follow-up. RESULTS: Among cohort members the SIR was 8.82 (95% CI 5.95-12.61) for mesothelioma and 1.61 (95% CI 1.26-2.04) for lung cancer. In subgroup analyses, the SIR for lung cancer in subjects hired in shipbuilding between 1974 and 1984 was 2.09 (95% CI 1.32-3.13). In the overall cohort, a borderline increased incidence was also found for stomach cancer (SIR = 1.53 95% CI 0.96-2.31). Internal comparisons within the cohort show that among men with high asbestos exposure level the relative risk was almost threefold for lung cancer (IRR = 2.94 95% CI 1.01-8.57). CONCLUSIONS: This cohort experienced an excess in the incidence of both mesothelioma and lung cancer, showing increasing incidence rates at higher level of asbestos exposure. For lung cancer, the relative incidence was highest among workers hired in shipbuilding between 1974 and 1984.

Mortality in a cohort of asbestos-exposed workers undergoing health surveillance.

BACKGROUND: The coastal area of Friuli Venezia Giulia (FVG) region, north-eastern Italy, was characterized by work activities in which asbestos was used until the early 1990s, particularly in shipbuilding. A public health surveillance program (PHSP) for asbestos-exposed workers was established, although limited evidence exists about the efficacy of such programs in reducing disease occurrence and mortality. OBJECTIVES: To compare mortality in a cohort of 2,488 men occupationally exposed to asbestos, enrolled in a PHSP in FVG between the early 1990s and 2008, with that of the general population of FVG and Italy. METHODS: Standardized Mortality Ratios (SMR), with 95% Confidence Interval (95% CI), for all causes, all cancers, lung (LC) and pleural cancer (PC) were estimated in the cohort and in subgroups of workers with the first hire in shipbuilding that caused asbestos exposure (<1974, 1974-1984, 1985-1994). RESULTS: A strong excess in mortality for PC with reference to FVG (SMR=6.87, 95% CI 4.45-10.17) and Italian population (SMR=13.95, 95% CI 9.02-20.64) was observed. For LC, the FVG-based SMR was 1.49 (95% CI 1.17-1.89) and the Italy-based 1.43 (95% CI 1.12-1.81). Mortality among workers with the first hire in shipbuilding before 1974 was high for PC (FVG-based SMR=8.98, 95% CI 5.56-13.75; Italy-based SMR=18.41, 95% CI 11.40-28.17) and for LC (FVG-based SMR =1.60, 95% CI 1.18-2.11; Italy-based SMR=1.54, 95% CI 1.14-2.03). Further, for LC between 1974 and 1984, the FVG-based SMR was 2.45 (95% CI 1.06-4.82), and the Italy-based SMR was 2.33 (95% CI 1.01-4.60). CONCLUSIONS: This cohort experienced an excess mortality for pleural and lung cancer, compared with regional and national populations. For lung cancer, the excess was stronger in workers with the first hire in shipbuilding before 1985, suggesting a key role of asbestos exposure.

First or Second Drop of Blood in Capillary Glucose Monitoring: Findings from a Quantitative Study.

UNLABELLED: For clinical nurses, especially those working in emergency departments, it is crucial to measure blood glucose (BG) in an accurate, timely, and safe manner. Many differences in practice exist with regard to use of the first or second drop of blood for testing, and no consistent guidelines are available for capillary BG testing at home or in ED settings. The purpose of this study is to evaluate the BG differences between the first and second drop of capillary blood collected from the same site in patients with type 1 diabetes. METHODS: A consecutive sample of 195 persons with type 1 diabetes who had washed their hands and were not suspected of having hypoglycemia were included in the study. Descriptive and inferential statistical analysis for non-normal distributed variables was performed. RESULTS: A strong correlation emerged between the BG reported in the first and the second drops (Spearman's rho test [rs] 0.979, P < .001; Pearson r 0.978, P < .001). The average BG values obtained from the first and second drops were 184.30 mg/dL (median, 166) and 187.6 mg/dL (median, 172), respectively, and thus the second drop showed higher glucose values compared with the first drop. However, BG values of the second drop were not higher in all occasions: whereas some evaluations reported higher BG values in the second drop capillary sample (n = 123), others reported higher values in the first drop (n = 65), and still others reported identical measurements in the first and second drops (n = 7). Five outliers were present with a BG difference from -39 to -53 mg/dL in the first drop compared with the second drop, and 3 outliers were present with a BG difference from +46 to +57 mg/dL in the first drop compared with the second drop. However, the differences that emerged were not affected by glucose concentration (P = .221). DISCUSSION: Using the first drop of blood in a patient with clean hands allows emergency nurses to perform the test more quickly, resulting in immediate information. Findings indicate that the first drop of blood is adequate for clinical decision making, but the clinician should use judgment if using protocols in which small values (eg, 6 mg/dL) are important, because the first drop is more likely to have a slightly lower value.

[Cancer mortality of residents near a steel factory in Udine (Friuli Venezia Giulia Region, Northern Italy)]. / La mortalità per tumori tra i residenti nell'area circostante un'acciaieria della zona industriale udinese.

OBJECTIVES: to evaluate the association between distance of residence from a steel factory, a point source of air pollution within an industrial area in Udine (Friuli Venezia Giulia Region, Northern Italy), and cancer mortality. DESIGN: retrospective study. To evaluate the association between mortality rates and distance from the source, a Stone test analysis for all cases occurred in the entire area was conducted. The significance level was determined using Monte Carlo simulations. SETTING AND PARTICIPANTS: a GIS mapped residential history of Friuli Venezia Giulia population was completed. Among residents within 5 km from the principal industrial plant of the area from 1989 to 2012, deaths caused by cancer were selected. Furthermore, according to the prevalent wind direction, an analysis was conducted also in a subgroup of residents located into the South-Western quadrant. A set of 8 bands with increasing distance from the point-source was defined. The total population was 37,473 inhabitants. MAIN OUTCOME MEASURES: in each band, observed and expected cancer-related deaths (calculated on the basis of mortality rates in the entire area) and standardized mortality ratios (SMRs) were computed to test for decline in risk of mortality at different distances from the main chimney. Stone test, in which a decline in risk of disease with an increase in distance from the source of pollution is tested, was used. RESULTS: the risk for all cancers and lung cancer was higher than expected. For male residents located within 2 km into the South-Western quarter there were 21 observed deaths from lung cancer vs. 13 expected (SMR: 1.62; p-value=0.02). CONCLUSION: despite the fact that in the whole area cancer mortality is not increased, this study seems to support evidence of an excess of cancer deaths, especially lung cancer among males, near a steel factory. However, the study has limitations because of the small number of cases and the lack of individual exposure data and information about confounders (e.g., smoke habits and professional exposure). Therefore, a possible cause-effect interpretation of this association should be considered with caution.

The Use of Antidepressant Medication before and after the Diagnosis of Amyotrophic Lateral Sclerosis: A Population-Based Cohort Study.

BACKGROUND: The prevalent use of antidepressants (ATDs) in patients with Amyotrophic Lateral Sclerosis (ALS) varies across cross-sectional and clinic-based published studies. This population-based cohort study assesses the real-world prevalence of the use of ATDs, its trajectory and the association of incident use with clinical characteristics. METHODS: All patients with incident ALS in the Friuli Venezia Giulia region, Italy, from 2002 to 2009, were identified through multiple sources including health databases. Diagnosis was validated through clinical documentation review. ATDs prescriptions from 2000 to 2011 were obtained from regional database. The trajectory was estimated through generalized estimating equations for repeated measures logistic regression and the Hazard ratio (HR) of initiating ATDs through multivariate proportional hazard Cox regression. RESULTS: In this cohort of 261 ALS cases, age-, sex-adjusted prevalence of the use of ATDs was 37.3%, higher than in general population. The trajectory increased by 16% in 1-year period across diagnosis. Age ≤67 years at diagnosis (HR 1.28, 95% CI 0.84-1.95) and bulbar onset (1.43, 95% CI 0.90-2.26) were positively associated with initiating ATDs after diagnosis. CONCLUSIONS: More than one-third of patients used ATDs. Depression may occur more frequently than previously reported. Depression may precede motor alterations and be related to both ALS diagnosis and progression.

Medication use during pregnancy, gestational age and date of delivery: agreement between maternal self-reports and health database information in a cohort.

BACKGROUND: Health databases are a promising resource for epidemiological studies on medications safety during pregnancy. The reliability of information on medications exposure and pregnancy timing is a key methodological issue. This study (a) compared maternal self-reports and database information on medication use, gestational age, date of delivery; (b) quantified the degree of agreement between sources; (c) assessed predictors of agreement. METHODS: Pregnant women recruited in a prenatal clinic in Friuli Venezia Giulia (FVG) region, Italy, from 2007 to 2009, completed a questionnaire inquiring on medication use during pregnancy, gestational age and date of delivery. Redeemed prescriptions and birth certificate records were extracted from regional databases through record linkage. Percent agreement, Kappa coefficient, prevalence and bias-adjusted Kappa (PABAK) were calculated. Odds Ratio (OR), with 95% confidence interval (95% CI), of ≥ 1 agreement was calculated through unconditional logistic regression. RESULTS: The cohort included 767 women, 39.8% reported medication use, and 70.5% were dispensed at least one medication. Kappa and PABAK indicated almost perfect to substantial agreement for antihypertensive medications (Kappa 0.86, PABAK 0.99), thyroid hormones (0.88, 0.98), antiepileptic medications (1.00, 1.00), antithrombotic agents (0.70, 0.96). PABAK value was greater than Kappa for medications such as insulin (Kappa 0.50, PABAK 0.99), antihistamines for systemic use (0.50, 0.99), progestogens (0.28, 0.79), and antibiotics (0.12, 0.63). Adjusted OR was 0.48 (95% CI 0.26; 0.90) in ex- vs. never smokers, 0.64 (0.38; 1.08) in < high school vs. university, 1.55 (1.01; 2.37) in women with comorbidities, 2.25 (1.19; 4.26) in those aged 40+ vs. 30-34 years. Gestational age matched exactly in 85.2% and date of delivery in 99.5%. CONCLUSIONS: For selected medications used for chronic conditions, the agreement between self-reports and dispensing data was high. For medications with low to very low prevalence of use, PABAK provides a more reliable measure of agreement. Maternal reports and dispensing data are complementary to each other to increase the reliability of information on the use of medications during pregnancy. Birth certificates provide reliable data on the timing of pregnancy. FVG health databases are a valuable source of data for pregnancy research.

Factors influencing the choice of a nursing or a non-nursing degree: a multicenter, cross-sectional study.

Current literature has paid increasing attention to the factors influencing career decisions; nevertheless, few studies have compared candidates that have chosen a nursing versus a non-nursing degree. A multicenter, cross-sectional study design was performed to explore whether or not certain individual variables and having inaccurate data about nursing as a profession influenced the choice of a non-nursing degree. Six non-nursing and three nursing degree programs offered by two public Italian universities were involved. A total of 507 students who had just enrolled in non-nursing degree programs and 202 in nursing degree programs were invited to complete a questionnaire comprising 12 closed items. Overall, from 40.0% to 57.1% of the variation in choosing a degree other than nursing was explained by variables such as age, and having inaccurate data on the nursing profession. For each year over 19 years of age, the likelihood that the student would decide to enroll in a nursing degree program increases. For each wrong answer reported on the questionnaire evaluating knowledge on nursing profession, there was a reduction of approximately six times in the likelihood that the student would enroll in a nursing degree program. Information regarding the nursing profession should be offered in early stages of life; in addition, offering accurate data on the profession is a key factor in evaluating the congruence of the career with the individual's personal motivations, aspirations, and talents.

Mercury, arsenic and selenium exposure levels in relation to fish consumption in the Mediterranean area.

In order to assess mercury (Hg), selenium (Se) and arsenic (As) exposure in the Mediterranean area, total mercury (THg), monomethylmercury (MeHg), Se and As levels were measured in umbilical cord blood and breast milk from Italian (n=900), Slovenian (n=584), Croatian (n=234) and Greek (n=484) women. THg, MeHg, As, and Se levels were also determined in blood samples of the same mothers from Italy and Croatia. In addition, THg and MeHg were determined in the same women's hair from all the countries involved in this study and As and Se levels were determined in the mother's urine samples from Italy, Croatia and Greece. Besides recording the consumption of other food items, the frequencies of fish consumption were assessed by detailed food frequency questionnaires, since fish represents an important source of Hg, Se and As in humans. The highest levels of THg and As were found in cord blood (Med((THg))=5.8 ng/g; Med((As))=3.3 ng/g) and breast milk (Med((THg))=0.6 ng/g; Med((As))=0.8 ng/g) from Greek women, while the highest Se levels were found in cord blood (Med=113 ng/g) from Italy. Significant linear correlations were found between Hg, Se and As in blood, cord blood and breast milk. In addition, significant relations were found between the frequencies of total fish consumption and biomarkers of As, MeHg and Se exposure, with the strongest Spearman rank coefficients between frequencies of total fish consumption and THg levels in cord blood (r(s)=0.442, p<0.001) or THg levels in hair (r(s)=0.421, p<0.001), and between frequencies of total fish consumption and As levels in cord blood (r(s)=0.350, p<0.001). The differences in Hg and As exposure between countries were probably due to different amounts of fish consumption and the consumption of different species of fish of different origin, while the highest Se levels in women from Italy were probably the consequence of the more frequent consumption of different non specific food items. Moreover, fish consumption, the possible common source of As, Hg and Se intake, could explain the correlations between the elements determined in cord blood, mother's blood or breast milk.

Feasibility study of a web application for self-report of anticancer treatment toxicities.

Collection of collateral effects related to toxicities suffered by patients being exposed to anticancer treatments is of crucial importance in clinical practice but also in oncological research. The present paper describes a web application called PaTOS for self-report of anticancer therapy toxicities, and its evaluation in a preliminary interface analysis and then in a feasibility study.

Prenatal mercury exposure and child neurodevelopment outcomes at 18 months: Results from the Mediterranean PHIME cohort.

INTRODUCTION: Neurotoxicity due to acute prenatal exposure to high-dose of mercury (Hg) is well documented. However, the effect of prenatal exposure to low Hg levels on child neurodevelopment and the question about "safety" of fish-eating during pregnancy remain controversial. International comparisons of Hg concentrations in mother-child biological samples and neurodevelopmental scores embedded in birth cohort studies may provide useful evidence to explore this issue. MATERIALS AND METHODS: The Mediterranean (Italy, Slovenia, Croatia, and Greece) cohort study included 1308 mother-child pairs enrolled in the Public Health Impact of long-term, low-level, Mixed Element exposure in a susceptible population EU Sixth Framework Programme (PHIME). Maternal hair and venous blood, cord blood and breast milk samples were collected, and total Hg (THg) levels were measured. Demographic and socioeconomic information, lifestyles and nutritional habits were collected through questionnaires at different phases of follow-up. Children at 18 months of age underwent neurodevelopmental testing using the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III). Multivariate linear and logistic regressions were performed, for each country, to assess the association between THg and BSID-III scores, obtaining adjusted ß coefficients and odds ratios (ORs). These values were used to conduct a meta-analysis, to explore possible heterogeneity among countries and to obtain combined estimates of the association between THg exposure and BSID-III scores. RESULTS: Median THg (ng/g) was: 704 in maternal hair, 2.4 in maternal blood, 3.6 in cord blood, and 0.6 in breast milk. THg concentrations were highest in Greece and lowest in Slovenia. BSID-III neurodevelopmental scores were higher in Croatia and Slovenia. The meta-analysis of multivariate linear models found an overall positive association between language composite score and receptive communication scaled score and increasing THg in maternal hair (n = 1086; ß = 0.55; 95%CI: 0.05-1.05 and n = 1075; ß = 0.12; 95%CI: 0.02-0.22, respectively). The meta-analysis of logistic regression models showed that the overall adjusted OR between THg in cord blood and suboptimal gross motor score was borderline significant (n = 882; OR = 1.03; 95%CI: 1.00-1.07). Heterogeneity was found across the four sub-cohorts for language composite score in maternal blood, and for fine motor scaled score in cord blood and breast milk. Language composite score and THg concentrations in maternal venous blood were positively related (n = 58; ß = 4.29; CI95% (-0.02, 8.60)) in Croatia and an increase of 1 ng/g of THg in maternal venous blood was associated with a reduced risk for children to fall in the lowest quintile of language score by 31% (n = 58; OR = 0.69; CI 95%: 0.37, 1.01). The comparison of ß coefficients obtained by multiple linear regression model showed an inverse association between fine motor score and THg concentrations in cord blood for Croatia (n = 54; ß = -0.53; CI 95%: -1.10, 0.04) and Slovenia (n = 225; ß = -0.25; CI 95%: -0.49, -0.01). In Slovenia THg level in breast milk was associated with suboptimal fine motor performance (n = 195; OR = 5.25; CI 95%: 1.36, 21.10). CONCLUSIONS: This study showed an inverse relation between THg levels and developmental motor scores at 18 months, although the evidence was weak and partially internally and externally inconsistent. No evidence of detrimental effects of THg was found for cognitive and language outcomes at these concentrations and age.

[Road traffic accidents in the province of Udine: estimation of drivers' injuries attributable to personal, environmental, and vehicle-related factors]. / Incidenti stradali in provincia di Udine: stima degli infortuni di conducenti attribuibili a fattori personali, ambientali e relativi al veicolo.

OBJECTIVE: To estimate injuries attributable to personal, environmental, and vehicle-related factors among drivers involved in road accidents in the province of Udine. DESIGN: Analysis of data contained in the ISTAT road accident reports. SETTING: Road traffic accidents with personal damage that occurred in the province of Udine from 1991 to 1998. MAIN OUTCOME MEASURES: Fractions of injuries and deaths attributable to various risk factors. RESULTS: From 1991 to 1998, 24261 drivers were involved in accidents: 462% were uninjured, 51.8% were non-fatally injured, and 2.0% died within 7 days. The greatest proportion of injuries (10.59%) was attributed to being on a two-wheeled vehicle. On the other hand, with respect to death the highest proportion of cases was attributed to driving during the night (29.19%) and to non-using seat belts and helmets (26.30%). CONCLUSIONS: This study provides information useful for establishing priorities for the prevention of road accidents and injuries.
