Asbestos Exposure and Malignant Mesothelioma in Construction Workers-Epidemiological Remarks by the Italian National Mesothelioma Registry (ReNaM).

Notwithstanding the ban in 1992, asbestos exposure for workers in the construction sector in Italy remains a concern. The purpose of this study is to describe the characteristics of malignant mesothelioma (MM) cases recorded by the Italian registry (ReNaM) among construction workers. Incident mesothelioma cases with a definite asbestos exposure have been analyzed. Characteristics of cases and territorial clusters of crude rates of MM in construction workers have been described, as well as the relation between asbestos use before the ban and the historical trend of workforce in the construction sector in Italy. ReNaM has collected 31,572 incident MM cases in the period from 1993 to 2018 and asbestos exposure has been assessed for 24,864 (78.2%) cases. An occupational exposure has been reported for 17,191 MM cases (69.1% of subjects with a definite asbestos exposure). Among them, 3574 had worked in the construction sector, with an increasing trend from 15.8% in the 1993-98 period to 23.9% in 2014-2018 and a ubiquitous territorial distribution. The large use of asbestos in construction sector before the ban makes probability of exposure for workers a real concern still today, particularly for those working in maintenance and removal of old buildings. There is a clear need to assess, inform, and prevent asbestos exposure in this sector.

Treatment patterns among patients with malignant pleural mesothelioma: An Italian, population-based nationwide study.

BACKGROUND: Malignant pleural mesothelioma (MPM) is a rare cancer with a poor prognosis. Centralization of rare cancer in dedicated centers is recommended to ensure expertise, multidisciplinarity and access to innovation. In Italy, expert centers for MPM have not been identified in all regions. We aimed to describe the treatment patterns among MPM patients across different Italian regions and to identify factors associated with the treatment patterns across the regions. METHODS: We performed an observational study on a random sample of 2026 MPM patients diagnosed in 2003-2008. We included 26 population-based registries covering 70% of the Italian population. To identify factors associated with treatment patterns, across the different regions, we fitted a multinomial logistic regression model adjusted by age, sex, stage, histology and hospital with thoracic surgical department. RESULTS: MPM patients mostly received chemotherapy alone (41%) or no cancer-directed therapy (36%) especially the older patients. The first course of treatment for MPM patients differed across regions. Patients from Piedmont, Liguria and Campania were more likely to receive no cancer-directed therapy; those living in Tuscany and Sicily were more likely to get surgery; patients from Marche and Lazio were more likely to receive chemotherapy. These differences were not explained by age, sex, stage, histology and availability of a thoracic surgery department. CONCLUSIONS: There is limited expertise available and lack of a network able to maximize the expertise available may contribute to explaining the results of our study. Our findings support the need to ensure the appropriate care of all MPM patients in reorganizing the health care services. KEY POINTS: Significant findings of the study: MPM patients mostly received chemotherapy alone or no cancer-directed therapy especially the older patients. The first course of treatment for MPM patients differed across Italian regions. WHAT THIS STUDY ADDS: Differences in MPM clinical management are not explained by the age, stage, histology nor by the availability of a thoracic surgery department. Limited expertise for MPM contribute to explaining the unequal access to appropriate care for MPM patients in Italy.

Association between anti-HBc positivity and hepatocellular carcinoma in HBsAg-negative subjects with chronic liver disease: A meta-analysis.

A meta-analysis was performed to ascertain to what extent hepatitis B surface antigen (HBsAg)-negative/anti-hepatitis B core (anti-HBc)-positive subjects with chronic liver disease are at a higher risk of developing hepatocellular carcinoma (HCC) than the anti-HBc-negative.All studies included had to fulfill the following characteristics and inclusion criteria: they investigated the relationship between HBsAg-negative/anti-HBc-positive serology and the occurrence of HCC, whether a case-control or cohort study, they provided relative risk (RR) or odds ratios (ORs) and 95% confidence intervals (CIs), were available as a full text written in English, and were published and indexed up to April 2015.Twenty-six original studies met the inclusion criteria, allowing a meta-analysis on 44,553 patients. The risk of HCC among the 9986 anti-HBc-positive subjects was 67% higher than in the 34,567 anti-HBc-negative (95% CI = 1.44-1.95, P < 0.0001). The results were similar when groups of patients with a different stage of liver disease (patients with chronic liver disease, patients with cirrhosis), with different ethnicity (Asian and non-Asian) and etiology (HCV and non-HCV) were considered. The risk of HCC was significantly higher in the 651 anti-HBs/anti-HBc-positive patients (RR = 1.36; 95% CI = 1.17-1.58, P = 0.03) and in the 595 anti-HBs-negative/anti-HBc-positive subjects (RR = 2.15; 95% CI = 1.58-2.92, P < 0.0001) than in the 1242 anti-HBs/anti-HBc negative. However, the RR from 8 studies indicated that the risk of HCC was 35% lower among the anti-HBs/anti-HBc-positive subjects compared to the anti-HBs-negative/anti-HBc-positive (RR = 0.65; 95% CI = 0.52-0.8, P < 0.0001).This meta-analysis shows that in HBsAg-negative subjects with chronic liver disease, anti-HBc positivity is strongly associated with the presence of HCC, an association observed in all subgroups according to the stage of the disease, etiology, and ethnicity.

Frequency of inappropriate medication prescription in hospitalized elderly patients in Italy.

BACKGROUND: Older people often need comprehensive treatment, including many medications, and polypharmacy is common. The aims of this cross-sectional investigation were to examine the potentially inappropriate medication during the hospitalization and to identify the factors that may influence such inappropriateness among elderly in Italy. METHODS: A sample of 605 individuals aged 65 years and older admitted in non-academic public acute care hospitals was randomly selected. Prescription of inappropriate medications were evaluated during the period from the day of admission to a randomly preselected day (index day). Beers Criteria were used to evaluate appropriateness. RESULTS: At least one potentially inappropriate medication prescription from the day of hospital admission to the index day has been observed in 188 patients (31.1%), and respectively 84.1% and 15.9% of them had received one or two inappropriate medications. A total of 15 medications was prescribed inappropriately to these 188 patients, for 215 times with a total of 1143 doses. The multivariate logistic regression analysis revealed that the significant predictors for having at least one potentially inappropriate medication prescription during the hospitalization were: patients having an elementary education level, a lower pre-admission performance-based measure of basic activities of daily living, having received an inappropriate drug before the hospitalization, a hospital stay in the general and in the specialties surgical wards, a longer length of hospital stay from the admission to the index day, and having received a higher number of drugs from the day of the hospital admission to the index day. The most prevalent inappropriate medications administered were ketorolac (27.4%), amiodarone (19.1%), and clonidine (11.2%). CONCLUSIONS: This study supports the need for clinical guidelines implementation to assist physicians in choosing the most appropriate drugs for the elderly and for effective education of all physicians.

Evaluation of the appropriate perioperative antibiotic prophylaxis in Italy.

BACKGROUND: The appropriate use of antibiotics prophylaxis in the prevention and reduction in the incidence of surgical site infection is widespread. This study evaluates the appropriateness of the prescription of antibiotics prophylaxis prior to surgery amongst hospitalized patients in the geographic area of Avellino, Caserta, and Naples (Italy) and the factors associated with a poor adherence. METHODS: A sample of 382 patients admitted to 23 surgical wards and undergoing surgery in five hospitals were randomly selected. RESULTS: Perioperative antibiotic prophylaxis was appropriate in 18.1% of cases. The multivariate logistic regression analysis showed that patients with hypoalbuminemia, with a clinical infection, with a wound clean were more likely to receive an appropriate antibiotic prophylaxis. Compared with patients with an American Society of Anesthesiologists (ASA) score ≥4, those with a score of 2 were correlated with a 64% reduction in the odds of having an appropriate prophylaxis. The appropriateness of the timing of prophylactic antibiotic administration was observed in 53.4% of the procedures. Multivariate logistic regression model showed that such appropriateness was more frequent in older patients, in those admitted in general surgery wards, in those not having been underwent an endoscopic surgery, in those with a higher length of surgery, and in patients with ASA score 1 when a score ≥4 was chosen as the reference category. The most common antibiotics used inappropriately were ceftazidime, sultamicillin, levofloxacin, and teicoplanin. CONCLUSIONS: Educational interventions are needed to improve perioperative appropriate antibiotic prophylaxis.

Hospital readmission prevalence and analysis of those potentially avoidable in southern Italy.

BACKGROUND: One quality indicator of hospital care, which can be used to judge the process of care, is the prevalence of hospital readmission because it reflects the impact of hospital care on the patient's condition after discharge. The purposes of the study were to measure the prevalence of hospital readmissions, to identify possible factors that influence such readmission and to measure the prevalence of readmissions potentially avoidable in Italy. METHODS: A sample of 2289 medical records of patients aged 18 and over admitted for medical or surgical illness at one 502-bed community non-teaching hospital were randomly selected. RESULTS: A total of 2252 patients were included in the final analysis, equaling a response rate of 98.4%. The overall hospital readmission prevalence within 30 days of discharge was 10.2%. Multivariate logistic regression analysis revealed that the proportion of patients readmitted within 30 days of discharge significantly increased regardless of Charlson et al. comorbidity score, among unemployed or retired patients, and in patients in general surgery. A total of 43.7% hospital readmissions were judged to be potentially avoidable. Multivariate logistic regression analysis showed that potentially avoidable readmissions were significantly higher in general surgery, in patients referred to hospital by an emergency department physician, and in those with a shortened time between discharge and readmission. CONCLUSION: Additional research on intervention or bundle of interventions applicable to acute inpatient populations that aim to reduce potentially avoidable readmissions is strongly needed, and health care providers are urged to implement evidence-based programs for more cost-effective delivery of health care.

Human papillomavirus infection: knowledge, attitudes, and behaviors among lesbian, gay men, and bisexual in Italy.

BACKGROUND: This cross-sectional study assess knowledge, attitudes, and behavior towards the human papillomavirus (HPV) and the vaccination among a random sample of 1000 lesbian, gay men, and bisexual women and men. METHODS: A face-to-face interview sought information about: socio-demographic characteristics, knowledge about HPV infection, perception of risk towards HPV infection and/or cervical, anal, and oropharyngeal cancers, perception of the benefits of a vaccination to prevent cervical, anal, and oropharyngeal cancers, sexual behaviors, health-promoting behaviors, and willingness to receive the HPV vaccine. RESULTS: Only 60.6% had heard about the HPV infection and this knowledge was significantly higher in female, in those being a member of a homosexual association, in those having had the first sexual experience at a younger age, in those having received information about the HPV infection from physicians, and in those having no need of information about HPV infection. A higher perceived risk of contracting HPV infection has been observed in those younger, lesbian and gay men, who have heard of HPV infection and knew the risk factors and its related diseases, who have received information about HPV infection from physicians, and who need information about HPV infection. Only 1.7% have undergone HPV immunization and 73.3% professed intent to obtain it in the future. The significant predictors of the willingness to receive this vaccine were belief that the vaccination is useful, perception to be at higher risk of contracting HPV infection, and perception to be at higher risk of developing cervical, anal, and oropharyngeal cancers. CONCLUSIONS: Information and interventions are strongly needed in order to overcome the lack of knowledge about HPV infection and its vaccination. Inclusion of boys in the national vaccination program and initiate a catch-up program for men who have sex with men up to 26 years may reduce their burden of HPV-related disease.

Public concerns and behaviours towards solid waste management in Italy.

A self-administered questionnaire investigated knowledge, perceptions of the risks to health associated with solid waste management, and practices about waste management in a random sample of 1181 adults in Italy. Perceived risk of developing cancer due to solid waste burning was significantly higher in females, younger, with an educational level lower than university and who believed that improper waste management is linked to cancer. Respondents who had visited a physician at least once in the last year for fear of contracting a disease due to the non-correct waste management had an educational level lower than university, have modified dietary habits for fear of contracting disease due to improper waste management, believe that improper waste management is linked to allergies, perceive a higher risk of contracting infectious disease due to improper waste management and have participated in education/information activities on waste management. Those who more frequently perform with regularity differentiate household waste collection had a university educational level, perceived a higher risk of developing cancer due to solid waste burning, had received information about waste collection and did not need information about waste management. Educational programmes are needed to modify public concern about adverse health effects of domestic waste.

Knowledge, attitudes, and preventive practices about colorectal cancer among adults in an area of Southern Italy.

BACKGROUND: Colorectal cancer (CRC) is the second most commonly diagnosed cancer for both sexes in developed countries. This study assessed the knowledge, attitudes, and preventive practices regarding CRC of adults in Italy. METHODS: A random sample of 1165 adults received a self-administered questionnaire on socio-demographic characteristics; knowledge regarding definition, risk factors, and screening; attitudes regarding perceived risk of contracting CRC and utility of screening tests; health-related behaviors and health care use; source of information. RESULTS: Only 18.5% knew the two main modifiable risk factors (low physical activity, high caloric intake from fat) and this knowledge was significantly associated with higher educational level, performing physical activity, modification of dietary habits and physical activity for fear of contracting CRC, and lower risk perception of contracting CRC. Half of respondents identified fecal occult blood testing (FOBT) as main test for CRC prevention and were more knowledgeable those unmarried, more educated, who knew the main risk factors of CRC, and have received advice by physician of performing FOBT. Personal opinion that screening is useful for CRC prevention was high with a mean score of 8.3 and it was predicted by respondents' lower education, beliefs that CRC can be prevented, higher personal perceived risk of contracting CRC, and information received by physician about CRC. An appropriate behavior of performing FOBT if eligible or not performing if not eligible was significantly higher in female, younger, more educated, in those who have been recommended by physician for undergo or not undergo FOBT, and who have not personal history of precancerous lesions and familial history of precancerous lesions or CRC. CONCLUSION: Linkages between health care and educational systems are needed to improve the levels of knowledge and to raise CRC screening adherence.

A survey of knowledge, attitudes and practices towards avian influenza in an adult population of Italy.

BACKGROUND: Several public health strategic interventions are required for effective prevention and control of avian influenza (AI) and it is necessary to create a communication plan to keep families adequately informed on how to avoid or reduce exposure. This investigation determined the knowledge, attitudes, and behaviors relating to AI among an adult population in Italy. METHODS: From December 2005 to February 2006 a random sample of 1020 adults received a questionnaire about socio-demographic characteristics, knowledge of transmission and prevention about AI, attitudes towards AI, behaviors regarding use of preventive measures and food-handling practices, and sources of information about AI. RESULTS: A response rate of 67% was achieved. Those in higher socioeconomic classes were more likely to identify the modes of transmission and the animals' vehicles for AI. Those older, who knew the modes of transmission and the animals' vehicles for AI, and who still need information, were more likely to know that washing hands soap before and after touching raw poultry meat and using gloves is recommended to avoid spreading of AI through food. The risk of being infected was significantly higher in those from lower socioeconomic classes, if they did not know the definition of AI, if they knew that AI could be transmitted by eating and touching raw eggs and poultry foods, and if they did not need information. Compliance with the hygienic practices during handling of raw poultry meat was more likely in those who perceived to be at higher risk, who knew the hygienic practices, who knew the modes of transmission and the animals' vehicles for AI, and who received information from health professionals and scientific journals. CONCLUSION: Respondents demonstrate no detailed understanding of AI, a greater perceived risk, and a lower compliance with precautions behaviors and health educational strategies are strongly needed.

Oral cancer and dentists: knowledge, attitudes, and practices in Italy.

The purpose of the survey was to assess through a mailed questionnaire the knowledge, attitudes, and behaviors regarding oral cancer and their relationship with different indicators in a random sample of 1000 dentists in Italy. Respondents know the major risk factors and only half identify the diagnostic procedures. One-third indicated the most common form and the early lesions and this knowledge was more likely in those graduated from dental school and attended a course on oral cancer in the previous year. Approximately two-thirds (64.8%) believed that they were prepared to perform an oral cancer examination and to palpate lymph nodes in patients' necks. Multiple logistic regression revealed that this positive attitude was significantly higher for those who graduated from medical school and for those who have attended a course on oral cancer in the previous year. Half of the dentists routinely perform an oral cancer examination on all patients and it was more likely by those graduated from dental school, those who know that squamous cell is the most common form of oral cancer and that an early oral cancer lesion usually is a small, painless red area, those who believed that they are prepared to perform an oral cancer examination and to palpate lymph nodes in patients' necks, those who have attended a course on oral cancer in the previous year, and those who claim they need information. The importance of health care professionals as communicators of public health messages should be emphasized.

Association between fruit and vegetable consumption and oral cancer: a meta-analysis of observational studies.

BACKGROUND: Oral cancer ranks as the seventh most common form of cancer worldwide. Recent reports have examined the effect of fruit and vegetable intake on the risk of oral cancer, but results are controversial. OBJECTIVE: A meta-analysis was performed to arrive at quantitative conclusions about the contribution of fruit and vegetable intakes to the occurrence of oral cancer. DESIGN: A comprehensive, systematic bibliographic search of medical literature published up to September 2005 was conducted to identify relevant studies. Separate meta-analyses were conducted for fruit and vegetable consumption. The effect of portion or daily intake of fruit or vegetables on the risk of oral cancer was calculated. A multivariate meta-regression analysis was performed to explore heterogeneity. This multivariate meta-regression analysis examined the effect of quality score, the type of cancers included, citrus fruit and green vegetable consumption, and the time interval for dietary recall of the studies on the role of fruit or vegetable consumption in the risk of oral cancer. The presence of publication bias was assessed with a funnel plot for asymmetry. RESULTS: Sixteen studies (15 case-control studies and 1 cohort study) met the inclusion criteria and were included in the meta-analysis. The combined adjusted odds ratio (OR) estimates showed that each portion of fruit consumed per day significantly reduced the risk of oral cancer by 49% (OR: 0.51; 95% CI: 0.40, 0.65). For vegetable consumption, the meta-analysis showed a significant reduction in the overall risk of oral cancer of 50% (OR: 0.50; 95% CI: 0.38, 0.65). The multivariate meta-regression showed that the lower risk of oral cancer associated with fruit consumption was significantly influenced by the type of fruit consumed and by the time interval of dietary recall. CONCLUSION: The consumption of fruit and vegetables is associated with a reduced risk of oral cancer.

Risky behaviors among motorcycling adolescents in Italy.

OBJECTIVE: To investigate the relationship between risky behaviors and motorcycling in adolescents in Italy. STUDY DESIGN: A questionnaire was administered to a random sample of 1000 adolescents attending randomly selected public secondary schools to assess personal characteristics and lifestyle; motorcycle and helmet use; behavior while driving a motorcycle; traffic-related accidents, and receipt of tickets. RESULTS: Of the 894 responders, 54% and 29.2% routinely use the helmet as driver or passenger, respectively. Routine helmet use was higher among males, current smokers, alcohol drinkers, and those who reported that at least one close friend used a helmet. Motorcycling after consuming alcohol was higher in males, in current smokers, and in those who used cell phones and were tired while driving. An accident in the past year occurred in 25.7% of riders and was significantly higher in those who used cell phones while driving and in those who were interested in learning about motorcycle use. Adolescents who reported always motorcycling over the speed limit were at lower risk of smoking, talking with the passenger, and using a cell phone while driving. Being male, being older, learning about motorcycle use from someone outside the family, talking with a passenger, and using a cell phone while driving increased the risk of receiving a ticket. CONCLUSIONS: Educational programs, legislative measures, and policies to reduce risk behaviors in adolescents who use motorcycles are needed.

Dental hygienists and oral cancer prevention: knowledge, attitudes and behaviors in Italy.

This study explored knowledge of risk factors and diagnostic procedures for oral cancer, attitudes and behavior among dental hygienists in Italy. A random sample of 500 dental hygienists received by mail a questionnaire focusing on demographics and practice characteristics, knowledge, attitudes and behaviors regarding oral cancer assessment practices. Almost all dental hygienists correctly indicated tobacco usage and having a prior oral cancer lesion as risk factors. Although 88.8% knew that the tongue is one of the two most common sites of oral cancer, only 13.5% identified the floor of the mouth. Less than half (42.8%) recognized that an early oral lesion usually is a small, painless and red area and only 4.2% knew the examination procedures of the tongue. Results of the multiple logistic regression showed that those dental hygienists who worked a higher number of hours and treated a lower number of patients in a week were more likely to indicate tobacco and alcohol use as risk factors for oral cancer. Higher number of years in practice, scientific journals and associations as sources of information about oral cancer, and knowledge that ventral lateral border of tongue is the most common site for oral cancer, significantly predicted compliance with oral cancer examination. Dental hygienists' sex, age, and years in practice were associated with a positive attitude towards oral cancer prevention. Further educational interventions in order to early detect and prevent oral cancer are strongly needed.

Knowledge and behaviors of primary care physicians on oral cancer in Italy.

We investigated the knowledge and behaviors of a random sample of 500 primary care physicians (PCPs) regarding oral cancer in Calabria (Italy). 87.6% and 64% indicated tobacco and alcohol use as risk factors, only 31.5% and 2.8% having a prior oral cancer lesion and older age. 60.9% knew that squamous-cell carcinoma is the most common form; 68.8% and 37.1% that the tongue and floor of the mouth were the two most common sites. Respectively 91.5% and 41.7% knew that leukoplakia and erythroplakia were the two conditions most likely to be associated with oral cancer. 17.6% of PCPs recognized that an early oral lesion usually is small and painless red area and 26.8% knew how to examine the tongue. PCPs who learned about oral cancer from scientific journals were more likely to indicate tobacco use as a risk factor for oral cancer and those who do not need additional information to indicate alcohol use as a risk factor. Oral examination was provided by 63.8% and 37.1% to those 40 years of age and older. Half of respondents asked about the personal patient's experience of oral cancer and about the patient's family, most about patients' tobacco and alcohol use. The odds of asking about patients' tobacco and alcohol use and of performing oral cancer examination were significantly higher for those who practiced medicine for a longer period. Additional training and continuing educational programs on prevention and early detection of oral cancer for PCPs are strongly needed.

Meta-analysis of residential exposure to radon gas and lung cancer.

OBJECTIVES: To investigate the relation between residential exposure to radon and lung cancer. METHODS: A literature search was performed using Medline and other sources. The quality of studies was assessed. Adjusted odds ratios with 95% confidence intervals (CI) for the risk of lung cancer among categories of levels of exposure to radon were extracted. For each study, a weighted log-linear regression analysis of the adjusted odds ratios was performed according to radon concentration. The random effect model was used to combine values from single studies. Separate meta-analyses were performed on results from studies grouped with similar characteristics or with quality scores above or equal to the median. FINDINGS: Seventeen case-control studies were included in the meta-analysis. Quality scoring for individual studies ranged from 0.45 to 0.77 (median, 0.64). Meta-analysis based on exposure at 150 Bq/m3 gave a pooled odds ratio estimate of 1.24 (95% CI, 1.11-1.38), which indicated a potential effect of residential exposure to radon on the risk of lung cancer. Pooled estimates of fitted odds ratios at several levels of randon exposure were all significantly different from unity--ranging from 1.07 at 50 Bq/m3 to 1.43 at 250 Bq/m3. No remarkable differences from the baseline analysis were found for odds ratios from sensitivity analyses of studies in which > 75% of eligible cases were recruited (1.12, 1.00-1.25) and studies that included only women (1.29, 1.04-1.60). CONCLUSION: Although no definitive conclusions may be drawn, our results suggest a dose-response relation between residential exposure to radon and the risk of lung cancer. They support the need to develop strategies to reduce human exposure to radon.
