How has the flu virus infected the Web? 2010 influenza and vaccine information available on the Internet.

BACKGROUND: The 2009-10 influenza pandemic was a major public health concern. Vaccination was recommended by the health authorities, but compliance was not optimal and perception of the presumed associated risks was high among the public. The Internet is increasingly being used as a source of health information and advice. The aim of the study was to investigate the characteristics of websites providing information about flu vaccine and the quality of the information provided. METHODS: Website selection was performed in autumn 2010 by entering eight keywords in two of the most commonly used search engines (Google.com and Yahoo.com). The first three result pages were analysed for each search, giving a total of 480 occurrences. Page rank was evaluated to assess visibility. Websites based on Web 2.0 philosophy, websites merely displaying popular news/articles and single files were excluded from the subsequent analysis. We analysed the selected websites (using WHO criteria) as well as the information provided, using a codebook for pro/neutral websites and a qualitative approach for the adverse ones. RESULTS: Of the 89 websites selected, 54 dealt with seasonal vaccination, three with anti-H1N1 vaccination and 32 with both. Rank analysis showed that only classic websites (ones not falling in any other category) and one social network were provided on the first pages by Yahoo; 21 classic websites, six displaying popular news/articles and one blog by Google. Analysis of the selected websites revealed that the majority of them (88.8%) had a positive/neutral attitude to flu vaccination. Pro/neutral websites distinguished themselves from the adverse ones by some revealing features like greater transparency, credibility and privacy protection. CONCLUSIONS: We found that the majority of the websites providing information on flu vaccination were pro/neutral and gave sufficient information. We suggest that antivaccinationist information may have been spread by a different route, such as via Web 2.0 tools, which may be more prone to the dissemination of "viral" information. The page ranking analysis revealed the crucial role of search engines regarding access to information on the Internet.

Polychlorinated biphenyls and non-Hodgkin's lymphoma: a case-control study in Northern Italy.

BACKGROUND: Polychlorinated biphenyls (PCBs) have been hypothesized to increase the risk of non-Hodgkin lymphoma (NHL), although conclusive evidence is still lacking. High levels of PCBs were found in soil in some areas close to a PCB-producing factory in Brescia, North Italy. We conducted a population-based case-control study among residents of the town to investigate the possible association between PCB pollution and NHL in this area. METHODS: We included both incident and deceased NHL cases, and a random sample of the town residents as controls, frequency matched to cases as regards age and gender. Exposure to PCBs was estimated on the basis of the lifetime residential history of cases and controls in four different areas of the town-A, B and C (polluted areas) and D (control area). RESULTS: A total of 495 cases (287 incident cases) and 1467 controls were enrolled. Positive associations were found between NHL and having resided for at least 10 years in the area A, the most polluted area (odds ratio, OR=1.8; p=0.02) and for having resided in any of the polluted areas considered together (A+B+C) (OR=1.4; p=0.08). However, no associations were evident for having resided 20 years or longer in the polluted areas or when analyzing the association with each subject's main residence in his/her lifetime. CONCLUSION: This study provides some evidence for an association between PCB exposure and NHL, though results should be considered with caution in the absence of individual biological measures of exposure.

Quality of online pharmacies and websites selling prescription drugs: a systematic review.

BACKGROUND: Online pharmacies are companies that sell pharmaceutical preparations, including prescription-only drugs, on the Internet. Very little is known about this phenomenon because many online pharmacies operate from remote countries, where legal bases and business practices are largely inaccessible to international research. OBJECTIVE: The aim of the study was to perform an up-to-date and comprehensive review of the scientific literature focusing on the broader picture of online pharmacies by scanning several scientific and institutional databases, with no publication time limits. METHODS: We searched 4 electronic databases up to January 2011 and the gray literature on the Internet using the Google search engine and its tool Google Scholar. We also investigated the official websites of institutional agencies (World Health Organization, and US and European centers for disease control and drug regulation authorities). We focused specifically on online pharmacies offering prescription-only drugs. We decided to analyze and report only articles with original data, in order to review all the available data regarding online pharmacies and their usage. RESULTS: We selected 193 relevant articles: 76 articles with original data, and 117 articles without original data (editorials, regulation articles, or the like) including 5 reviews. The articles with original data cover samples of online pharmacies in 47 cases, online drug purchases in 13, consumer characteristics in 15, and case reports on adverse effects of online drugs in 12. The studies show that random samples with no specific limits to prescription requirements found that at least some websites sold drugs without a prescription and that an online questionnaire was a frequent tool to replace prescription. Data about geographical characteristics show that this information can be concealed in many websites. The analysis of drug offer showed that online a consumer can get virtually everything. Regarding quality of drugs, researchers very often found inappropriate packaging and labeling, whereas the chemical composition usually was not as expected in a minority of the studies' samples. Regarding consumers, the majority of studies found that not more than 6% of the samples had bought drugs online. CONCLUSIONS: Online pharmacies are an important phenomenon that is continuing to spread, despite partial regulation, due to intrinsic difficulties linked to the impalpable and evanescent nature of the Web and its global dimension. To enhance the benefits and minimize the risks of online pharmacies, a 2-level approach could be adopted. The first level should focus on policy, with laws regulating the phenomenon at an international level. The second level needs to focus on the individual. This approach should aim to increase health literacy, required for making appropriate health choices, recognizing risks and making the most of the multitude of opportunities offered by the world of medicine 2.0.

[When health "sells": presence and characteristics of health-related advertising in the Italian press]. / Quando la salute "vende": presenza e caratteristiche di pubblicità a contenuto sanitario sulla stampa italiana.

The authors evaluated the amount of health-related advertising that appeared in major Italian newspapers and magazines during the months of July 2009 and November 2009. Advertisements related to health (as defined by the World Health Organization) were found to be widely present in the Italian press. Health promotion messages given by health institutions must therefore compete with the above advertisements that deal with health issues usually for purely commercial purposes.

Neoplastic and inflammatory skin disorders and serum levels of polychlorinated biphenyls in a population living in a highly polluted area.

BACKGROUND: Although polychlorinated biphenyls (PCBs) have been classified as human carcinogens for their association with melanoma, few data are available for other skin lesions. OBJECTIVES: To investigate the prevalence of skin disorders in a highly PCB polluted area in northern Italy, with locally produced food as the main source of human contamination, and evaluate the association between skin lesions and PCB serum levels, taking account of possible confounders. MATERIALS & METHODS: Thirty-three PCB congeners were quantitatively assessed and a total of 189 subjects were equally divided into three groups using the tertiles of total PCB serum concentrations. All subjects underwent a clinical examination and were interviewed on their risk factors and history of skin diseases. RESULTS: No statistically significant difference was found in the prevalence of skin cancer, nevi, pigmentary disorders as well as inflammatory and infectious skin diseases among the three PCB exposure groups. It should be noted that the use of questionnaires to assess subjects' past sun exposure and photoprotection is intrinsically flawed due to random error. CONCLUSION: Our study does not support the hypothesis that chronic PCB exposure, through the ingestion of contaminated food, determines an increased risk of developing skin diseases.

"Save 30% if you buy today". Online pharmacies and the enhancement of peripheral thinking in consumers.

PURPOSE: Online pharmacies (OPs) are recognized as a potential threat to public health. The growth of an unregulated global drugs market risks increasing the spread of counterfeit medicines which are often delivered to consumers without a medical prescription. The aim of the study was to assess the strategies of argumentation that OPs adopt in their marketing. METHODS: A sample of 175 OPs was analyzed using the content-analysis method, and evaluated by relying on the Elaboration Likelihood Model (ELM) of persuasion. RESULTS: Almost 80% of the sample of OPs did not ask for a medical prescription by the consumer's physician. The selling arguments used included privacy policy, economic, quality, and service issues. About one-third of the OPs did not declare any side-effects regarding the drugs offered. CONCLUSION: Our results show that OPs advertise their products in an argumentative fashion that enhances consumers' peripheral reflection: by analogically playing with the selling of other commodities, they magnify aspects of the online trade that consumers might find convenient, but overshadow the nature and risks of the actual products they sell.

Italian hospitals on the web: a cross-sectional analysis of official websites.

BACKGROUND: Although the use of the Internet for health purposes has increased steadily in the last decade, only a few studies have explored the information provided by the websites of health institutions and no studies on the on-line activities of Italian hospitals have been performed to date. The aim of this study was to explore the characteristics of the contents and the user-orientation of Italian hospital websites. METHODS: The cross-sectional analysis considered all the Italian hospitals with a working website between December 2008 and February 2009. The websites were coded using an ad hoc Codebook, comprising eighty-nine items divided into five sections: technical characteristics, hospital information and facilities, medical services, interactive on-line services and external activities. We calculated a website evaluation score, on the basis of the items satisfied, to compare private (PrHs) and public hospitals, the latter divided into ones with their own website (PubHs-1) and ones with a section on the website of their Local Health Authority (PubHs-2). Lastly, a descriptive analysis of each item was carried out. RESULTS: Out of the 1265 hospitals in Italy, we found that 419 of the 652 public hospitals (64.3%) and 344 of the 613 PrHs (56.1%) had a working website (p = 0.01). The mean website evaluation score was 41.9 for PubHs-1, 21.2 for PubHs-2 and 30.8 for PrHs (p < 0.001).Only 5 hospitals out of 763 (< 1%) provided specific clinical performance indicators, such as the nosocomial infection rate or the surgical mortality rates. Regarding interactive on-line services, although nearly 80% of both public and private hospitals enabled users to communicate on-line, less than 18% allowed the reservation of medical services, and only 8 websites (1%) provided a health-care forum. CONCLUSIONS: A high percentage of hospitals did not provide an official website and the majority of the websites found had several limitations. Very few hospitals provided information to increase the credibility of the hospital and user confidence in the institution. This study suggests that Italian hospital websites are more a source of information on admissions and services than a means of communication between user and hospital.

The world of e-patients: A content analysis of online social networks focusing on diseases.

OBJECTIVE: as the participatory Web developed to create virtual worlds and communities, health institutions and activists discovered Web 2.0 tools, in particular the creation of health-related online social networks. To analyze the existing online social networks dedicated to health issues, we performed an active search on the Internet for such Web sites and analyzed their features according to the content analysis method. METHODS: the study was performed in September and October 2009. We analyzed a sample of health social networks for patients, selected using four common search engines. A codebook was elaborated to investigate four areas: general information; technical characteristics and utilities; characteristics of the Web site and contents, both general and related to the online community. RESULTS: the search led to a sample of 41 social networks. Twenty-three Web sites (56.1%) were dedicated to several diseases, the others to one only. Although the majority of the sample (87.8%) provided a way to contact the Web site, only five (12.2%) showed the name of the author or operating organization. Eight Web sites (19.5%) indicated one or more sponsors, and nine (22.0%) named one or more partners. It was often hard to tell whether an institution mentioned was a sponsor or a partner. Five Web sites (12.2%) enabled users to buy health-related products online. Twelve Web sites (29.3%) offered users the chance to search for doctors, and 12 (29.3%) gave therapeutic information. Two Web sites (4.9%) published aggregate statistical data about the patients registered with the social network. CONCLUSIONS: the data reveal the high heterogeneity of health-related social networks and raise interesting considerations on such controversial topics as the quality of online health information, research perspectives, interactivity, and empowerment. In particular, our findings are relevant to criticism regarding the openness and transparency of these Web sites, the use of personal data, and privacy issues.

Cyberdrugs: a cross-sectional study of online pharmacies characteristics.

As e-commerce and online pharmacies (OPs) arose, the potential impact of the Internet on the world of health shifted from merely the spread of information to a real opportunity to acquire health services directly. Aim of the study was to investigate the offer of prescription drugs in OPs, analysing their characteristics, using the content analysis method. The research performed using the Google search engine led to an analysis of 118 online pharmacies. Only 51 (43.2%) of them stated their precise location. Ninety-six (81.4%) online pharmacies did not require a medical prescription from the customer's physician. Online pharmacies rise complex issues in terms of patient-doctor relationship, consumer empowerment, drug quality, regulation and public health implications.

Marketing and pricing strategies of online pharmacies.

Internet and e-commerce have profoundly changed society, the economy, and the world of health care. The web offers opportunities to improve health, but it may also represent a big health hazard since it is a basically unregulated market with very low consumer protection. In this paper we analyze marketing and pricing strategies of online pharmacies (OPs). Our analysis shows that OPs use strategies that would be more suitable for a commodity market than for drugs. These strategies differentiate according to variety (brand or generic), quality, quantity, and target group. OPs are well aware that the vacuum in the legislation allows them to reach a target of consumers that pharmacies cannot normally reach, such as those who would like to use the drug without consulting a physician (or, even worse, against the physician's advice). In this case, they usually charge a higher price, reassure the users by minimizing on the side effects, and induce them to bulk purchase through sensible price discounts. This analysis suggests that the selling of drugs via the Internet can turn into a "public health risk", as has been pointed out by the US Food and Drug Administration.

Online consultations in cyberpharmacies: completeness and patient safety.

Many online pharmacies that serve as a substitute for original or personal medical prescriptions use a health questionnaire for consumers to complete on their Web site for buying prescription-only medicines. A content analysis of online medical questionnaires from a sample of online pharmacies (OPs) examined their completeness. Fifty-seven questionnaires were identified in which online pharmacies sought health status assessment from online purchasers. To evaluate the questionnaires, a checklist tallied their characteristics, including general features, medical history requested, and involvement of the consumer's doctor. Drug allergies were queried in 55 OPs (96.5%) and other allergies in 40 (70.2%). All of the questionnaires asked whether the consumer had suffered or was currently suffering from a particular illness, but a question about past surgery was present in 23 sites (40.3%) only; 40 sites (70.2%) asked women if they were pregnant or breastfeeding. Only 30 pharmacies out of 57 (52.6%) asked if the consumer's family doctor was aware of his/her intention of buying online and an even lower percentage (19.3%) asked if the purchase was based on a medical diagnosis rendered by a physician. Less than 20% of the pharmacies asked for the name, address, or telephone number of the consumer's family doctor. The results confirm the inadequacy of online pharmacy medical questionnaires in the assessment of health status for prescribing drugs. The results suggest that these questionnaires aim more at giving the consumer a false sense of health assurance than performing an effective assessment of his or her health status relative to the drug purchase.

Polychlorinated biphenyl serum levels, thyroid hormones and endocrine and metabolic diseases in people living in a highly polluted area in North Italy: A population-based study.

Polychlorinated biphenyls (PCBs) are persistent organic pollutants produced until the 1980s, which they are still present worldwide. They have been associated with metabolic and endocrine diseases and hypertension in humans, but definite evidence is lacking. A chemical factory producing PCBs caused a heavy pollution in an urban area in Northern Italy. We aimed to evaluate present PCBs serum levels according to demographic and lifestyle variables and their associations with endocrine and metabolic diseases and hypertension in the resident general population. A random sample of 816 adults aged 20-79 years (mean ± SD: 49.1 ± 16.5 years) was enrolled in a cross-sectional population-based study. The participants provided a fasting blood sample for laboratory analysis and were face-to-face interviewed about the presence of chronic diseases. The serum level of total PCBs was computed as the sum of 33 PCB congeners. The median serum level of lipid-adjusted total PCBs was 435.2 and 95th centile was 2154.9 ng/g lipid. Medium and high chlorinated PCBs with immunotoxic and endocrine disrupting activity contributed most to total PCB serum levels, particularly PCBs 138, 153, 170, 180 and 194. The serum levels of total PCBs and of PCB functional groups were positively associated with age and negatively with female gender, education, smoking habit and BMI, and not associated with serum levels of thyroid hormones and TSH and glycaemia and with presence of endocrine diseases, diabetes and hypertension by multivariable analysis. Subgroup analyses according to gender, age and BMI provided similar results. In conclusion, this study shows a long-term persistence of past exposure to PCBs and does not support the hypothesis of an association between PCB exposure and prevalence of endocrine and metabolic diseases and hypertension.

Serum levels of polychlorinated biphenyls and risk of non-Hodgkin lymphoma: A hospital-based case-control study.

Polychlorinated biphenyls (PCB) have been classified by the International Agency for Research on Cancer (IARC) in Group 1 as carcinogenic to human, based on sufficient evidence in humans of an increased risk of cutaneous malignant melanoma and limited evidence for non-Hodgkin lymphoma (NHL). However present findings on the association of PCB exposure and NHL are still controversial. This study examined the relationship between PCB serum levels and risk of NHL in a Northern Italy area (Brescia province), where a chemical factory produced PCBs from 1938 to 1984, causing human contamination. A case-control study of 215 NHL patients and 215 control subjects was conducted. Cases and controls were assayed for serum levels of 33 PCB congeners. No associations were found between risk of NHL and serum levels of total PCBs (OR = 0.51; 95% CI: 0.25-1.04 for highest vs lowest quartile) or specific PCB congeners. The study confirmed a strong association of NHL with HCV infection (OR = 3.60; 95% CI: 1.30-10.02). This case-control study does not support the hypothesis of an association between current serum levels of PCBs and NHL development in the general population.

Polychlorinated biphenyls and thyroid hormone serum concentrations among people living in a highly polluted area: a cross-sectional population-based study.

BACKGROUND: Polychlorinated biphenyls (PCBs) may interact with several thyroid functions. Severe environmental pollution by PCBs has been observed in Brescia, Italy, due to the presence of a factory that produced these compounds until 1984. OBJECTIVES: We aimed to investigate the correlation between serum levels of total PCBs and PCB 153 and thyroid hormone serum levels in adults in a cross-sectional population-based study. METHODS: A total of 527 subjects were enrolled; they were face-to-face interviewed about their history of thyroid disease and provided a blood sample under fasting conditions. The serum levels of free and total triiodothyronine (FT3 and TT3), thyroxine (FT4 and TT4) and thyroid-stimulating hormone (TSH), anti-thyroperoxidase (anti-TPO) and anti-thyroglobulin (anti-TGA), and lipid-adjusted total PCBs and PCB 153 were determined. RESULTS: There was no statistically significant difference in total PCB and PCB 153 concentrations in subjects with and without thyroid disease. Inverse, weak, statistically significant correlations were found between total PCBs and FT3 (Spearman's r=-0.09) and between total PCBs and PCB 153 and TSH (Spearman's r=-0.16 and -0.12, respectively). However, multiple regression analysis with FT3 and TSH serum levels as dependent variables and total PCBs and PCB 153 serum levels as predictors, including age, gender and BMI, showed a positive, rather than negative, association of PCBs and PCB 153 with FT3 and no association with TSH. CONCLUSIONS: This study does not support the hypothesis that relatively high PCB environmental exposure can determine substantial alterations in thyroid function among adult people.

[Brescia Local Health Autority Population Database: a method based on current data for monitoring chronic diseases and management]. / La Banca dati assistito dell'ASL di Brescia: una metodologia basata su dati correnti per il monitoraggio delle patologie croniche e per la gestione delle risorse.

OBJECTIVE: The Local Health Autority (ASL) of Brescia has activated an innovative method of surveillance, based on the integration ofcurrent databases in a single database, Population Database (BDA), for monitoring the prevalence of chronic diseases in the area. METHOD: The BDA has been set up using automatic record-linkages of databases regarding disease exemptions, drug treatments, hospital admissions and outpatient specialist visits. This enabled us to calculate the prevalence of various chronic diseases (single or grouped) and the gross average expenditure per person for each disease group. RESULTS: Out of the 1,092,201 people in the Brescia ASL, 275,601 had at least one chronic disease (prevalence 252.3/1,000). Diseases ofthe circulatory system were the most frequent (169.1/1,000), followed by diabetes mellitus (36 6/1,000). Having had an organ transplant was the condition with the highest per-person expenditure (Euro 16,170/year). The highest total expenditure was associated with circulatory diseases, because of the high prevalence (Euro 470,377,413). CONCLUSION: A single computerised data base is capable of achieving epidemiological aims (assessing population health status) as well as managerial and health care aims (resources management, control of the appropriateness of services, adaptation of diagnostic-therapeutic methods to international guidelines and standards).

[Use of information systems for managing healthcare services in a long-term care facility]. / Il Sistema Informativo come strumento per la gestione della variabilità quotidiana nell'assistenza in una Residenza Sanitaria Assistenziale.

The aim of this study was to evaluate the use of a patient data management information system in a long-term care facility in Brescia (Italy). A survey was conducted among the facility's nursing staff to investigate work organization and identify critical areas that could be improved through the implementation of an information system. A specific patient data management system was then developed and performance indicators were identified. Performance indicators were measured before implementation and then at 6 and 30 months. Managing daily patient healthcare through the use of an information system has allowed an improvement of the appropriateness and quality of care, as well as improved efficiency by saving valuable nursing time.

Plasma levels of polychlorinated biphenyls and risk of cutaneous malignant melanoma: A hospital-based case-control study.

Polychlorinated biphenyls (PCB) have been classified by the International Agency for Research on Cancer (IARC) in Group 1 as carcinogenic to human, based on sufficient evidence in humans of an increased risk of cutaneous malignant melanoma (CMM), however few studies have been done in the general population. This study examined the relationship between PCB plasma levels and risk of CMM adjusting for sun sensitivity and sun exposure in a province of Northern Italy (Brescia), where a chemical factory produced PCBs from 1938 to 1984 causing human contamination. A case-control study of 205 CMM patients and 205 control subjects was conducted. Cases and controls were assayed for plasma levels of 33 PCB congeners. No associations was found between risk of CMM and plasma levels of total PCB (OR = 0.81; 95% CI: 0.34-1.96 for highest vs lowest quartile) or specific congeners. The study confirmed the association with light skin colour (OR = 3.00; 95% CI: 1.91-4.73), cumulative lifetime UV exposure (OR = 2.56; 95% CI: 1.35-4.85) and high level of education (OR = 1.45; 95% CI: 1.03-2.05). This case-control study does not support the hypothesis of an association between current plasma levels of PCBs and CMM development in the general population.

Temporal trends of polychlorinated biphenyls serum levels in subjects living in a highly polluted area from 2003 to 2015: a follow-up study.

INTRODUCTION: A chemical factory located in Brescia, an industrialized town in North Italy, produced polychlorinated biphenyls (PCBs) since the 1930s to the 1980s, determining a relevant pollution of soil, food and people. Since 2001, following a survey carried out in the general population living in the town, the individuals with PCB serum levels higher than the reference entered a follow-up study. METHODS: We performed a prospective cohort study including subjects with at least three PCB measures during the period 2003-2015. We evaluated the temporal trends of total PCB serum levels, the most common PCB congeners (PCB 138,153, 170, 180, 194 and 209), and toxic equivalency of dioxin-like PCBs using univariate and multivariate mixed models with and without a cubic-spline term for time. RESULTS: A total of 128 subjects were enrolled (46.1% males, mean age at enrolment 57.7 years). The geometric mean of PCBs decreased from 35.4ng/ml at 0-3 years to 29.3ng/ml at 4-8 years and to 23.0ng/ml at 9-12 years. A 3.8% reduction of total PCB serum levels per year was estimated using both univariate and multivariate mixed models adjusted for age; a similar reduction was found for the most common PCB congeners and for toxic equivalency. Total PCB serum levels decreased over time for each age group: -3.9%, -4.0% and -3.4% for subjects aged ≤55 years, 56-65 and ≥66 years, respectively. CONCLUSION: A significant decrease of serum concentrations of PCBs was observed in subjects with high serum levels of these chemicals at enrolment over a twelve year period. The decrease was evident for each PCB congener and age group.

Substantial decline of polychlorinated biphenyls serum levels 10years after public health interventions in a population living near a contaminated site in Northern Italy.

INTRODUCTION: Polychlorinated biphenyls (PCBs) are persistent pollutants classified among endocrine disruptors and human carcinogens. In an urban area in Northern Italy (Brescia), a chemical factory producing PCBs from 1938 to 1984 caused soil and food pollution. Since the discovering of the environmental pollution in the area in 2001, various public health interventions have been implemented to avoid human contamination. METHODS: Two independent surveys were carried out in 2003 and 2013 using the same study design and methods. A random sample of the adult general population living in four areas of the town with different soil contamination level was enrolled in both surveys. Investigation included serum levels of 24 PCB congeners and of other common clinical-chemical parameters and questions about residential and occupational history as well as current and past diet and consumption of locally produced food. 537 subjects were tested in the 2003 and 488 in the 2013 survey. RESULTS: Total PCB serum levels showed a strong correlation with age (Spearman r=0.71 in 2003 and r=0.80 in 2013), but not with gender. Consumers of food produced in the most polluted area had higher total PCB serum levels (median 15.6 and 4.7ng/ml in 2003 and 2013, respectively) than non-consumers (4.1 and 2.3ng/ml) and consumers of food produced in non-polluted areas (6.5 and 1.9ng/ml), with increasing trend of PCB serum levels with cumulative local food intake. PCB serum levels from 2003 to 2013 survey declined by around half in all age groups, especially among the youngest people. The total PCB reduction was found to be due to a combination of a birth cohort effect (-41% every 10years) and survey period effect (-18% in 2013 versus 2003), with medium chlorinated CB congeners showing the most relevant reduction (-30%) between the two surveys. High chlorinated CBs were more strongly associated with birth cohort (-46% every 10years): in the 2013 survey they represented 58% of total PCBs in 60-79years old while they were 37% among the under 40s with a median value 20 times higher in the oldest than in the youngest (3.1 versus 0.16ng/ml). CONCLUSIONS: PCBs serum levels declined from the 2003 to 2013 survey though they are still high in the elderly mainly because of past intake of locally produced contaminated food. Present findings suggest that PCBs food chain contamination and human absorption have been interrupted successfully in the area since discovery of the pollution in 2001.

Crisis Communication in the Area of Risk Management: The CriCoRM Project.

BACKGROUND: During the last H1N1 pandemic has emerged the importance of crisis communication as an essential part of health crisis management. The Project aims specifically to improve the understanding of crisis communication dynamics and effective tools and to allow public health institutions to communicate better with the public during health emergencies. DESIGN AND METHODS: THE PROJECT WILL PERFORM DIFFERENT ACTIVITIES: i) state of the art review; ii) identification of key stakeholders; iii) communicational analysis performed using data collected on stakeholder communication activities and their outcomes considering the lessons learnt from the analysis of the reasons for differing public reactions during pandemics; iv) improvement of the existing guidelines; v) development of Web 2.0 tools as web-platform and feed service and implementation of impact assessment algorithms; vi) organization of exercises and training on this issues. EXPECTED IMPACT OF THE STUDY FOR PUBLIC HEALTH: In the context of health security policies at an EU level, the project aims to find a common and innovative approach to health crisis communication that was displayed by differing reactions to the H1N1 pandemic policies. The focus on new social media tools aims to enhance the role of e-health, and the project aims to use these tools in the specific field of health institutions and citizens. The development of Web 2.0 tools for health crisis communication will allow an effective two-way exchange of information between public health institutions and citizens. An effective communication strategy will increase population compliance with public health recommendations. Significance for public healthThe specific aim of the project is to develop a European strategy approach on how to communicate with the population and with different stakeholders groups involved in the crisis management process, based on an analysis of the communication process during the H1N1 pandemic (content analysis of press releases, press coverage and forum discussions) and on interviews with key stakeholders in health crisis communication. The development of web 2.0 tools, providing rapid responses will allow real-time verification of awareness of social trends and citizens' response. Furthermore, the project would like to offer these resources to the EU Public Health Institutions and EU citizens to improve their interaction, and hence reinforce citizens' right to patient-centred health care. The project proposal has been designed in accordance with the general principles of ethics and the EU Charter of Fundamental Rights with regard to human rights, values, freedom, solidarity, and better protection of European citizens.
