Trauma focused-cognitive behavioral therapy training effectiveness in promoting professional development of psychotherapists working with unaccompanied minors in Greece: a non-blinded randomized control trial.

The need to develop psychotherapists' skills to respond to current treatment challenges, such as addressing trauma due to the refugee crisis, is increasing. However, there is a dearth of evidencebased training for psychotherapists who work with refugees, especially in frontline countries. A randomly selected sample of 80 clinicians working with unaccompanied minors (UAMs) in Greek accommodation centers nationwide participated in an intensive trauma-focused cognitive behavioral therapy (TF-CBT) training (n=44) or a control-group (n=36) and completed the Professional Quality of Life Scale, the Work and Meaning Inventory and a questionnaire to assess knowledge and therapeutic skills, in pre-andpost measurements. Clinicians with 1-3 years of experience with refugees reported higher burnout (p=0.012, M=25.78 vs M=22.04) and secondary traumatic stress than those with less than a year (p=0.014, M=22.03 vs M=18.04). Positive meaning at work increased in both groups at post-test (TF-CBT group: p=0.019, M=15 vs M=13.6, and control group: p<0.001, M=15.17 vs M=13.42). The TF-CBT training group outperformed the control group in knowledge and skills (p=0.021, M=10.15 vs M=8.75) and identified a lower number of children with post-traumatic stress disorder symptoms (p=0.009, M=6.94 vs M=4.33) post-training. This study provides preliminary evidence on TF-CBT training effectiveness in equipping psychotherapists to work with UAMs, while their professional quality of life warrants further research.

The role and importance of epidemiology in transfusion medicine.

Transfusion therapy is an indispensable form of treatment, and an important element of the public health system. Due to its origin, blood's clinical use is associated with various risks that may cause adverse reactions and events. Progress in quality and safety of blood components has eliminated numerous risks, especially those of infectious origin. However, some risks cannot be predicted, while others cannot always be prevented. Globalisation and climate change constantly favour the spread of infectious agents. Against this, epidemiology plays a central role in ensuring the safety of transfusion treatment, by continuous surveillance and timely identification of risks, and in the development of routine and additional tests as measures for risk mitigation. As a quantitative discipline based on research methods, epidemiology is a method of reasoning; it relies on the generation and testing of hypotheses; it utilises other scientific resources, particularly in the field of blood donation and blood transfusion, thus having many applications. The main focus falls on transfusion-transmissible infections, and on environmental or occupational diseases, injuries, disabilities and death causes at large. The practice of epidemiology relies on a systematic approach and measurement of disease frequencies. Surveillance is a key element, involving continuously gathering, analysing, and evaluating data regarding diseases, morbidity and mortality, and disseminating the conclusions of the analyses to relevant competent authorities; in this way, action is taken for disease prevention and control. Surveillance systems also provide an important tool for risk assessment, a method to assess and characterise the critical parameters in the functionality of equipment, systems or processes of using scientific data in order to estimate the magnitude of any health effect that derives from decisions of policy makers. Epidemiological surveillance, particularly for the incidence of adverse reactions and adverse events associated with blood transfusion at the national and international levels, has demonstrated the importance of multidisciplinary cooperation between blood and public health services.

Clinical severity classes in COVID-19 pneumonia have distinct immunological profiles, facilitating risk stratification by machine learning.

Objective: Clinical triage in coronavirus disease 2019 (COVID-19) places a heavy burden on senior clinicians during a pandemic situation. However, risk stratification based on serum biomarker bioprofiling could be implemented by a larger, nonspecialist workforce. Method: Measures of Complement Activation and inflammation in patientS with CoronAvirus DisEase 2019 (CASCADE) patients (n = 72), (clinicaltrials.gov: NCT04453527), classified as mild, moderate, or severe (by support needed to maintain SpO2 > 93%), and healthy controls (HC, n = 20), were bioprofiled using 76 immunological biomarkers and compared using ANOVA. Spearman correlation analysis on biomarker pairs was visualised via heatmaps. Linear Discriminant Analysis (LDA) models were generated to identify patients likely to deteriorate. An X-Gradient-boost (XGB) model trained on CASCADE data to triage patients as mild, moderate, and severe was retrospectively employed to classify COROnavirus Nomacopan Emergency Treatment for covid 19 infected patients with early signs of respiratory distress (CORONET) patients (n = 7) treated with nomacopan. Results: The LDA models distinctly discriminated between deteriorators, nondeteriorators, and HC, with IL-27, IP-10, MDC, ferritin, C5, and sC5b-9 among the key predictor variables during deterioration. C3a and C5 were elevated in all severity classes vs. HC (p < 0.05). sC5b-9 was elevated in the "moderate" and "severe" categories vs. HC (p < 0.001). Heatmap analysis shows a pairwise increase of negatively correlated pairs with IL-27. The XGB model indicated sC5b-9, IL-8, MCP1, and prothrombin F1 and F2 were key discriminators in nomacopan-treated patients (CORONET study). Conclusion: Distinct immunological fingerprints from serum biomarkers exist within different severity classes of COVID-19, and harnessing them using machine learning enabled the development of clinically useful triage and prognostic tools. Complement-mediated lung injury plays a key role in COVID-19 pneumonia, and preliminary results hint at the usefulness of a C5 inhibitor in COVID-19 recovery.

Life Satisfaction in a Clinical and a Nonclinical Group of Older People: The Role of Self-Compassion and Social Support.

Despite the health-promoting role of life satisfaction, little is known about its determining factors in older people with mental health problems compared to nonclinical participants. This study provides preliminary data into the role of social support, self-compassion, and meaning in life on older people's life satisfaction within both clinical and non-clinical populations. In total, 153 older adults (age ≥60) completed the Satisfaction With Life Scale (SWLS), the Self-Compassion Scale (SCS), the Meaning in Life Questionnaire (MLQ), and questions for relational variables. Hierarchical logistic regression analysis revealed that determinants of life satisfaction were self-kindness (B = 2.036, p = .001) and intimate friends' network (B = 2.725, p = .021), while family relationships were found to be significant among the clinical group (B = 4.556, p = .024). Findings are discussed in relation to incorporating self-kindness and rapport with family in clinical work with older adults to better promote their well-being.

Ethics in transfusion medicine: Are the intricate layers of ethics all universal? A global view.

Ethical principles have been considered, and in several respects regulated, along the entire blood procurement chain from donor motivation to transfusion to the patient. Consent of donors and voluntary non-remunerated donation are fields which have been addressed by codes of ethics and legislation. Caring for donor health is an area of further development of ethical standards. In part, blood products have also become a market, where commercial principles may synergize, but also creating issues in equality and maintaining human dignity that challenge societal solutions. At the bedside, the main global challenge remains to procure enough blood products for each patient in medical need. Allocation of rare blood, ethical evaluation of transfusion triggers, attitudes towards refusing blood transfusion and provision of blood products to remote settings are areas which should receive consideration.

Biochar application as a soil potassium management strategy: A review.

The established practices of intensive agriculture, combined with inadequate soil Κ replenishment by conventional inorganic fertilization, results in a negative environmental impact through the gradual exhaustion of different forms of K reserves in soils. Although biochar application as soil amendment has been established as an approach of integrated nutrient management, few works have focused on the impact of biochar application to soil K availability and crop uptake. This review provides an up-to-date analysis of the published literature, focusing on the impact of biochar in the availability of potassium in soil and crop growth. First, the effect of biomass type and pyrolysis temperature on potassium content of biochar was assessed. Second, the influence of biochar addition to the availability of potassium in soil and on potassium soil dynamics was examined. Finally, alternative methods for estimating available K in soils were proposed. The most promising biomasses in terms of potassium content were grape pomace, coffee husk and hazelnut husk however, these have not been widely utilized for biochar production. Higher pyrolysis temperatures (>500 °C) increase the total potassium content whereas lower temperatures increase the water-soluble and exchangeable potassium fractions. It was also determined that biochar has considerable potential for enhancing K availability through several distinct mechanisms which eventually lead directly or indirectly to increased K uptake by plants. Indirect mechanisms mainly include increased K retention capacity based on biochar properties such as high cation exchange capacity, porosity, and specific surface area, while the direct supply of K can be provided by K-rich biochar sources through purpose-made biochar production techniques. Research based on biochar applications for soil K fertility purposes is still at an early stage, therefore future work should focus on elucidating the mechanisms that define K retention and release processes through the complicated soil-biochar-plant system.

Knowledge, Attitudes and Perception of Mosquito Control in Different Citizenship Regimes within and Surrounding the Malakasa Open Accommodation Refugee Camp in Athens, Greece.

The study aims to evaluate the Knowledge, Attitude and Perception (KAP) of different societal groups concerning the implementation of targeted community-based mosquito surveillance and control interventions in different citizenship regimes. Targeted surveys were carried out within Malakasa camp for migrants and refugees, neighboring residential areas and urban areas in the wider Athens metropolitan area to investigate different knowledge levels and the role that both local and migrant communities can play in the implementation of community-based interventions based on their attitudes and perceptions. A scoring system was used to rate the collected responses. Results indicate different levels of KAP among the various groups of respondents and different priorities that should be considered in the design and execution of community interventions. Findings indicate a lower level of Knowledge Attitudes and Perceptions for the migrants, while the rate of correct answers for Perception significantly improved for migrants following a small-scale information session. The study highlights disparities in the levels of knowledge for certain public health issues and the feasibility of certain approaches for alleviating health-related challenges such as mosquito-borne diseases. Findings suggest that essential preparedness is needed by public authorities to respond to public health challenges related to migration and the spread of vector-borne diseases.

Gender Differences in Bullying Reflect Societal Gender Inequality: A Multilevel Study With Adolescents in 46 Countries.

PURPOSE: Social patterns in bullying show consistent gender differences in adolescent perpetration and victimization with large cross-national variations. Previous research shows associations between societal gender inequality and gender differences in some violent behaviors in adolescents. Therefore, there is a need to go beyond individual associations and use a more social ecological perspective when examining gender differences in bullying behaviors. The aim of the present study was twofold: (1) to explore cross-national gender differences in bullying behaviors and (2) to examine whether national-level gender inequality relates to gender differences in adolescent bullying behaviors. METHODS: Traditional bullying and cyberbullying were measured in 11-year-olds to 15-year-olds in the 2017/18 Health Behaviour in School-aged Children study (n = 200,423). We linked individual data to national gender inequality (Gender Inequality Index, 2018) in 46 countries and tested their association using mixed-effects (multilevel) logistic regression models. RESULTS: Large cross-national variations were observed in gender differences in bullying. Boys had higher odds of perpetrating both traditional and cyberbullying and victimization by traditional bullying than girls. Greater gender inequality at country level was associated with heightened gender differences in traditional bullying. In contrast, lower gender inequality was associated with larger gender differences for cyber victimization. DISCUSSION: Societal gender inequality relates to adolescents' involvement in bullying and gendered patterns in bullying. Public health policy should target societal factors that have an impact on young people's behavior.

Study of the Association of Insecure Attachment With the Dehumanization and Self-Dehumanization of Patients Hospitalized With Psychotic Disorder and Organic Disease.

Introduction Dehumanization is the phenomenon that concerns the non-attribution of humanness to other human beings and has two dimensions, animalistic and mechanistic. The aim of the present study is to study dehumanization and self-dehumanization in patients with psychosis and organic disease. Methods The sample consisted of 200 people who were hospitalized in Athens, Greece, in 2017. Participants were asked to answer the dehumanization questionnaire, the mechanistic self-dehumanization scale, the human nature and human uniqueness characteristics questionnaire, and the adult attachment questionnaire.  Results It was found that patients with organic disease and patients with psychosis do not perform mechanistic and animalistic dehumanization of themselves. Still, it seems that insecure attachment (anxiety and obsession) contributes positively to their mechanistic dehumanization and negatively to their mechanistic self-dehumanization. From the insecure attachment, only the dimensions of stress and obsession affect the mechanistic dehumanization.  Conclusions It is important to take measures to train specialists in the hospital so that they can establish a safe therapeutic relationship with the patient so that patients will not resort to dehumanization and self-dehumanization as a defense against the stress of hospitalization.

Prevalence of Overweight and Obesity and Associated Diet-Related Behaviours and Habits in a Representative Sample of Adolescents in Greece.

Excessive body weight during adolescence represents a significant public health problem worldwide. Identifying factors associated with its development is crucial. We estimated the prevalence of overweight and obesity in a representative sample of 11, 13 and, 15-year-olds living in Greece and explored the association with diet-related behaviours and habits. Self-reported data on weight, height, diet-related behaviours and habits were used from 3816 students (1898 boys, 1918 girls) participants in the Greek arm of the international Health Behaviour in School-Aged Children (HBSC) study during 2018. Overweight and obesity were defined using the 2007 WHO growth charts classification. Prevalence of overweight was 19.4% in the total sample, 24.1% for boys and 14.7% for girls, and prevalence of obesity was 5.3% in the total sample, 7.3% for boys and 3.4% for girls, respectively. In the total sample, overweight (including obesity) was positively associated with male gender, low family affluence, skipping breakfast, and being on a diet, and inversely associated with age and being physically active. Eating rarely with the family was positively associated with overweight only among boys and eating snacks/meals in front of screens only among girls. No association was noted for eating in fast-food restaurants, consuming vegetables, fruits, sweets, and sugar-sweetened beverages.

Using latent profile analysis to understand burnout in a sample of Greek teachers.

OBJECTIVES: The purpose of this study was to identify burnout profiles in Greek secondary school teachers using latent profile analysis. METHODS: Burnout was measured using the Maslach Burnout Inventory (MBI) in a sample of 460 teachers. RESULTS: In partial agreement with the literature, latent profile analysis revealed four profiles: Burnout (high on all three dimensions of the MBI), Engagement (low on all three), Overextended (high on exhaustion only) and Ineffective (high on inefficacy only). The most common profile among the teachers in this sample was overextended (50%). Teachers in each profile behaved differently with regard to job satisfaction and attitudes towards school-related sources of problems. In particular, Burnt-out teachers were more negative than the Engaged ones in almost all variables assessed, except educational policy, while differences between the two intermediate profiles were less marked. Engaged teachers showed the highest levels of job satisfaction, followed by Overextended and Ineffective, with Burnt-out teachers showing the lowest levels. CONCLUSIONS: The derived profiles and their different attitudes showed the significance of all three dimensions of burnout syndrome. In practical terms, interventions appropriately targeted to each profile can be designed and implemented to prevent or reduce burnout.

Adolescents' Online Pornography Exposure and Its Relationship to Sociodemographic and Psychopathological Correlates: A Cross-Sectional Study in Six European Countries.

The aim of the study was to assess the prevalence of online exposure to pornography in European adolescents and its relationship to sociodemographic and psychopathological correlates. A cross-sectional school-based survey of 10,930 adolescents (5211 males/5719 females), aged 14-17 years old (mean age 15.8 ± 0.7) was carried out in six European countries (Greece, Spain, Poland, Romania, the Netherlands, and Iceland). Anonymous self-completed questionnaires covered exposure to pornography, internet use and dysfunctional internet behavior, and psychopathological syndromes (measured by Achenbach's Youth Self-Report). The prevalence of any online exposure to pornography was 59% overall and 24% for exposure at least once a week. The likelihood of online exposure to pornography was greater in male adolescents, heavier internet users, and those who displayed dysfunctional internet behavior. Country-specific analyses confirmed that the gender effect existed in every country, although its strength varied, from an odds ratio of 1.88 in Poland to 14.9 in Greece. Online exposure to pornography was shown to be associated with externalizing problem scale scores, especially rule-breaking and aggressive behavior, but also associated with higher scores in competences, namely activities and social competence. Exposure to pornography is ubiquitous, more relevant to boys, and is associated with both positive qualities/competences and externalizing behavioral problems.

The role of urbanisation in the spread of Aedes mosquitoes and the diseases they transmit-A systematic review.

BACKGROUND: This systematic review aims to assess how different urbanisation patterns related to rapid urban growth, unplanned expansion, and human population density affect the establishment and distribution of Aedes aegypti and Aedes albopictus and create favourable conditions for the spread of dengue, chikungunya, and Zika viruses. METHODS AND FINDINGS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review was conducted using the PubMed, Virtual Health Library, Cochrane, WHO Library Database (WHOLIS), Google Scholar, and and the Institutional Repository for Information Sharing (IRIS) databases. From a total of 523 identified studies, 86 were selected for further analysis, and 29 were finally analysed after applying all inclusion and exclusion criteria. The main explanatory variables used to associate urbanisation with epidemiological/entomological outcomes were the following: human population density, urban growth, artificial geographical space, urban construction, and urban density. Associated with the lack of a global definition of urbanisation, several studies provided their own definitions, which represents one of the study's limitations. Results were based on 8 ecological studies/models, 8 entomological surveillance studies, 7 epidemiological surveillance studies, and 6 studies consisting of spatial and predictive models. According to their focus, studies were categorised into 2 main subgroups, namely "Aedes ecology" and "transmission dynamics." There was a consistent association between urbanisation and the distribution and density of Aedes mosquitoes in 14 of the studies and a strong relationship between vector abundance and disease transmission in 18 studies. Human population density of more than 1,000 inhabitants per square kilometer was associated with increased levels of arboviral diseases in 15 of the studies. CONCLUSIONS: The use of different methods in the included studies highlights the interplay of multiple factors linking urbanisation with ecological, entomological, and epidemiological parameters and the need to consider a variety of these factors for designing effective public health approaches.

Dehumanization of Hospitalized Patients and Self-Dehumanization by Health Professionals and the General Population in Greece.

Introduction Dehumanization is defined as the denial to people of their humanness. It is distinguished into animalistic and mechanistic dehumanization. The aim of this study is to examine whether professionals in a public hospital dehumanize the patient and self-dehumanize. Methods We used the Dehumanization Questionnaire, the Mechanistic Self-Dehumanization Scale, the Human Nature and Human Uniqueness Characteristics Questionnaire, the General Causality Orientation Scale and the Adult Attachment Questionnaire. The sample consisted of 135 mental health professionals (20 from a general hospital and 115 from a psychiatric hospital), 134 other health professionals from the general hospital and 84 people from the general population. Results  Health professionals dehumanize the hospitalized patient more than the general population. The secure attachment acts protectively on self-dehumanization and negatively on the dehumanization of the hospitalized patient. Finally, autonomous people are not self-dehumanized. Conclusions Our findings indicate that measures should be taken for health professionals so that they do not dehumanize the patient.

Complications of blood donation reported to haemovigilance systems: analysis of eleven years of international surveillance.

BACKGROUND AND OBJECTIVES: The International Haemovigilance Network collects aggregate data on complications of blood donation from member haemovigilance systems (HVS). We analysed the data collected in 2006-2016 in order to learn from it and consider future improvements. MATERIALS AND METHODS: National HVS entered annual data on donation complications and on annual whole blood and apheresis donations in the 'ISTARE' (International Surveillance of Transfusion Adverse Reactions and Events) online database. We calculated national and aggregate donation complication rates. RESULTS: Twenty-four HVS provided data for 138 country years (CY; median 7 CY, IQR 2-8), covering 155 M donations. The overall complication rate was 6·3/1000 donations and the median country rate 3·2/1000 (IQR 1·1-10·1). Overall and severe complication rates varied considerably between HVS. Vasovagal reactions (VVR) were most commonly reported: 4·6/1000 donations, median country rate 3·1/1000 donations (IQR 0·6-7·7). Rare complications included generalized allergic reaction (0·10/100 000) and major blood vessel injury (category available since 2015; 0·12/100 000). Eighteen HVS reported complications of whole blood donation (WBD) and apheresis separately (89 CY, 101·6 M WBD and 26·3 M apheresis donations). The median country VVR rate was 3·4/1000 WBD (IQR 1·0-9·1) and 1·5/1000 apheresis donations (1·0-4·2). Rates of venepuncture-related complications tended to be higher for apheresis: the median country rate of reported haematomas was 0·39/1000 WBD (IQR 0·31-1·2) vs. 4·2/1000 apheresis donations (0·69-5·6). CONCLUSION: International reporting allows HVS to study rates of blood donation complications and capture information about very rare events. The present variability of reporting and severity assessment hampers comparisons between HVS and requires further work.

Peer loss: Posttraumatic stress, depression, and grief symptoms in a traumatized adolescent community.

In our prospective study, 168 adolescents exposed directly or indirectly to the same traumatic event-a fatal school bus accident-in which seven students were killed instantly, were assessed for post-traumatic stress, depression and grief symptoms at 2- and 18-months post-accident. Prevalence rates of likely PTSD and depression were noted across all types of physical proximity exposure: 77.6% and 48.1% respectively in the indirectly exposed group, 79.4% and 47.1% respectively in the directly in-the-area exposed group, and 77.8% and 42.1% respectively in the directly in-bus exposed group. One-fifth experienced high and unremitting levels of grief symptoms over time ("persistent grief"); 17% with initially high levels of grief symptoms showed a decrease at 18 months but were still within the low medium range ("towards recovery"); 39% with initially medium/high grief symptoms reported low levels of grief at the follow-up ("recovery"); and 23% of the participants experienced grief symptoms that remained persistently low ("resilient"). The absence of both PTSD and depression at 18 months predicted adjustment to loss, whereas the absence of depression at 18 months predicted a recovering course of grief. The findings highlight the impact of high levels of post-traumatic stress and depression symptoms on the long-term persistent grief outcome.

Diet-Related Behaviors and Diet Quality among School-Aged Adolescents Living in Greece.

Prevalence of diet-related behaviors (i.e., breakfast consumption, eating with the family) and their association with a 17-point diet quality score, constructed on the basis of reported frequency (in days/week) of vegetable, fruit, sweets and sugar-sweetened beverages consumption, was investigated among 3525 adolescents (51.5% girls) aged 11, 13 and 15 years, who were participants in the Greek arm of the international Health Behaviour in School-Aged Children (HBSC) cross-sectional study, during 2018. Almost one-third (32.9%) of the sample had breakfast ≤1 day/weekdays, 20.2% rarely ate with the family, 26.1% had a meal while watching TV ≥5 days/week, 31.7% had a snack in front of a screen ≥5 days/week and 24.1% ate in fast-food restaurants at least once/week. Multivariable ordinal logistic regression revealed that eating breakfast ≤1 day/weekdays compared to 4-5 days/weekdays (Odds ratio (OR): 1.56, 95% con-fidence interval (CI): 1.34-1.82), eating rarely with the family compared to almost every day (OR: 1.35, 95% CI: 1.13-1.60) and eating in fast-food restaurants ≥2 times/week vs. rarely (OR: 4.59, 95% CI: 3.14-6.70) were associated with higher odds of having poor diet quality. High frequency of having meals/snacks in front of a screen/TV was also associated with poor diet quality. Efforts to prevent or modify these behaviors during adolescence may contribute to healthier diet.

Autism Spectrum Disorders in Greece: Nationwide Prevalence in 10-11 Year-Old Children and Regional Disparities.

Autism spectrum disorders (ASD) constitute a public health concern with increasing prevalence worldwide. We aimed to estimate prevalence and age at diagnosis in Greece, where no large-scale prevalence study has ever been conducted. Aggregate data were collected on ASD diagnoses by gender and calendar year of diagnosis up to 2019, for children born in 2008 and 2009, from the Centers for Educational and Counseling Support, which evaluate children to receive special educational support in school. Coverage was 87.1% of centers and 88.1% of schoolchildren born in 2008-9. ASD prevalence overall was 1.15% (1.83% males, 0.44% females; ratio 4.14:1), ranging from 0.59% to 1.50% in Greece's 13 regions. In five regions, prevalence differed significantly between centers. Overall, only 3.8% of diagnoses were made before the fourth year after birth and 42.7% before the sixth year, with considerable variation between regions. Approximate mean age at diagnosis was six years and one month, and about three months earlier for girls than for boys. Our results provide evidence-based information to guide service planning and development at national and regional levels. Particular attention should be paid to smoothing out inequalities regarding service accessibility and provision. Emphasis should be given to earlier identification and diagnosis of ASD.

On lifestyle trends, health and mosquitoes: Formulating welfare levels for control of the Asian tiger mosquito in Greece.

The expansion of urban ecosystems and climate change, both outcomes of massive lifestyle changes, contribute to a series of side effects such as environmental deterioration, spread of diseases, increased greenhouse gas emissions and introduction of invasive species. In the case of the Athens metropolitan area, an invasive mosquito species-the Asian tiger mosquito (Aedes albopictus)-has spread widely in the last decade. This spread is favoured within urban environments and is also affected by changing climatic trends. The Asian tiger mosquito is accompanied by risks of mosquito-borne diseases, greater nuisance levels, and increased expenses incurring for its confrontation. The main aims of this paper are (i) to estimate the various costs associated with the control of this invasive species, as well as its health and nuisance impacts, (ii) to evaluate the level of citizens' well-being from averting these impacts and (iii) to record citizens' and experts' perceptions regarding alternative control measures. Evidence shows that experts tend to place a high value on mosquito control when associated with serious health risks, while citizens are more sensitive and concerned about the environmental impacts of control methods. The synthesis of results produced by the current study could act as a preliminary guide for the estimation of societal welfare from the confrontation of similar problems in the context of a complex ecosystem.

Gambling involvement and problem gambling correlates among European adolescents: results from the European Network for Addictive Behavior study.

PURPOSE: Worldwide, concern has grown over the expansion of gambling among adolescents, who have an increased likelihood of developing risk-taking behaviors. This study aimed to increase knowledge of problem gambling among adolescents in seven European countries and to assess the effect of demographic and lifestyle factors recorded in the European Network for Addictive Behavior survey (https://www.eunetadb.eu). METHODS: A cross-sectional school-based study (n = 13,284) was conducted in Germany, Greece, Iceland, The Netherlands, Poland, Romania and Spain. Anonymous self-completed questionnaires included socio-demographic data, internet usage characteristics, school achievement, parental control, the Internet Addiction Test, the South Oaks Gambling Screen-Revised for Adolescents Test and Achenbach's Youth Self-Report. RESULTS: 12.5% of the participants reported last year gambling activities either online or offline. 3.6% of the study participants and 28.1% of gamblers (either online or offline) were at risk or had a gambling problem. The study results showed that a higher proportion of adolescents was either at risk or had a gambling problem among males, in the older age group, when the parental educational level was lower/middle, and in the absence of siblings. Furthermore, being at risk or having a gambling problem was associated with lower age at first use of the internet, lower school grades, using the internet 6-7 days per week, and problematic internet use. At risk or problem gamblers had higher scores on all scales of problem behavior and lower scores (lower competence) on activities and academic performance. CONCLUSIONS: Our findings underline the need for better gambling legislation and suggest the importance of developing social responsibility tools that may help diminish adolescent gambling involvement, with special attention to males.
