RESUMO
BACKGROUND: leukaemia is the most prevalent form of childhood cancer, an overall rare condition in childhood. Even few cases occurring in a small community can cause considerable apprehension among the population. From 2014 to 2017, 4 cases of childhood cancer occurred in Valle di Ledro, a municipality of 5,300 inhabitants in Province of Trento (Northern Italy), and a group of concerned citizens asked provincial health authorities for an investigation. OBJECTIVES: to address the community's health needs by verifying the hypothesis of a cluster of childhood cancer and through effective risk communication activities. DESIGN: retrospective cohort analysis based on data from the Cancer registry of the Autonomous Province of Trento and data collected from hospital discharge records. The communication activities were carried out according to the recommendations published by Epidemiologia&Prevenzione in 2016 in a Supplement "Childhood cancers, risk factors and investigation models for the evaluation of spatio-temporal clusters". SETTING AND PARTICIPANTS: Valle di Ledro, a municipality of 5,300 inhabitants in the Province of Trento. The participants in risk communication process were: city council; grassroot committee of concerned parents; health workforce of different services (epidemiology, cancer registry, public health; environmental health; primary health care; personnel of the Environmental Protection Agency; journalists; general population. The participants in the statistical analyses were: children of 0-14 years of age who were diagnosed a cancer from 1998 to 2014 in the Province of Trento (N. 212); leukaemia (N. 84) and acute lymphoblastic leukaemia (N. 66) incident cases in the period 1998-2017 in Trento province. MAIN OUTCOME MEASURES: verification of the presence of a cluster of childhood cancers; degree of consensus and collaboration of the different community stakeholders to the survey procedures and acceptance of the final results; atmosphere in public assemblies and feedback in the local press. RESULTS: a total of 212 incident cancer cases in children 0-14 years have been registred in Province of Trento from 1998 to 2014, leukaemia in 35% (N. 74) cases. From 2015 to 2017, another 10 cases of leukaemia occurred, for a total of 84 cases of leukaemia from 1998 to 2017. In the years from 1998 to 2017, in Valle di Ledro, taking the Italian population as reference group, the standardized incidence ratios (SIRs) were the following: cancer, all types 1,47 (IC95% 0,40-3,76); leukaemia 3,39 (IC95% 0,70-9,90), LLA 2,81 (IC95% 0,34-10,16). No cluster emerged from the geographical analyses. From the very beginning of the risk management approach, a decision-making working group was set up applying a participatory approach. Group members included the city council and the local committee of concerned parents and experts from different services of the local health unit. Data analyses was delegated to a technical working group that reported back to the decision-making group. Members of the technical working group were supervised by external experts. Following this approach, it was possible to establish a climate of trust and credibility. The involvement of all stakeholders right from the start in a totally transparent process was a key element of success. CONCLUSIONS: the cluster hypothesis was rejected for both childhood cancer (all types) and leukaemia (all types and ALL). The implementation of the risk communication process recommended by the AIE guidelines was successful in establishing a climate of reciprocal trust that allowed to overcome inevitable moments of conflict in a productive manner. Thanks to this positive atmosphere, the communication of the results of the statistical analyses was effective in reassuring the population.

Communication is an essential but complex aspect of the management of a suspected cancer cluster. In this paper, it is summarized how this issue has been addressed in the guidelines on the management of cluster developed by the Centers for Disease Control and Prevention (CDCs) in the US and by the Institut de Veille Sanitaire in France. The US guidelines recommend a communication strategy that includes a basic plan, which must be adapted to all steps of the process, a transparent communication, the involvement of the local community, the definition of the subjects involved, and the development of the necessary tools. The French guidelines emphasize that the management of these alarms is both a health and a policy issue, highlighting that this fact has important implications in the communication strategy. Guidelines are useful tools; however, they can lead to an excessive use of proceduralization if the ability to detect features of each cluster is not improved. It is therefore essential to create the opportunity to discuss and share experiences among stakeholders who are actually entitled to respond to these alarms. Some experiences of cancer cluster in Tuscany are used as examples.
RESUMO
(1) The Russian invasion of Ukraine forced many people to leave their country and seek asylum in various European countries, with serious consequences from a health perspective. In this context, we describe the health measures undertaken by AcToVax4NAM Consortium Countries (Cyprus-Germany-Greece-Italy-Malta-Poland-Romania-Spain) to prevent Vaccine-Preventable Disease (VPD) outbreaks in the context of mass movements of populations that resulted from the crisis in Ukraine. (2) We collected information on the vaccinations offered to Ukrainians in the Consortium Countries. (3) All these countries have provided Temporary Protection (TP) status to refugees from Ukraine and have followed the recommendations of European and International Agencies to offer them vaccinations according to the National Immunisation Programmes. The COVID-19 vaccination is offered in all countries with regard to the general population. Most countries provide information on TP and access to health/vaccination services in the Ukrainian language. (4) The information collected shows a common effort to ensure the adequate planning of health and vaccination services for refugees from Ukraine and, very often, to include them in the national vaccination offer. It is important that this initial response towards people who have fled Ukraine will be continued following the emergency but, more importantly, that it serves as a best practice towards all migrants and refugees entering the EU.
RESUMO
Objectives: Access to vaccination for newly arrived migrants (NAMs) is a relevant concern that requires urgent attention in EU/EEA countries. This study aimed to develop a General Conceptual Framework (GCF) for understanding how to improve vaccination coverage for NAMs, by characterizing and critically analyzing system barriers and possible strategies to increase vaccination. Methods: A theoretical conceptualization of the GCF was hypothesized based on conceptual hubs in the immunization process. Barriers and solutions were identified through a non-systematic desktop literature review and qualitative research. The GCF guided the activities and facilitated the integration of results, thereby enriching the GCF with content. Results: The study explores the vaccination of NAMs and proposes strategies to overcome barriers in their vaccination process. It introduces a framework called GCF, which consists of five interconnected steps: entitlement, reachability, adherence, achievement, and evaluation of vaccination. The study also presents barriers and solutions identified through literature review and qualitative research, along with strategies to enhance professionals' knowledge, improve reachability, promote adherence, achieve vaccination coverage, and evaluate interventions. The study concludes by recommending strategies such as proximity, provider training, a migrant-sensitive approach, and data collection to improve vaccination outcomes for NAMs. Conclusion: Ensuring equitable access to healthcare services, including vaccination, is crucial not only from a humanitarian perspective but also for the overall public health of these countries.

Variation in how individuals cope behaviourally and physiologically with stressors is widespread and can have a significant impact on life-history traits and fitness. Individual coping styles are characterised by differential behavioural and adrenocortical reactivity to various challenges. As stress hormones can affect the production of reactive chemical species and the antioxidant status, individuals with different coping styles may differ also in oxidative status. Field studies on wild mammalian populations are few in number and none so far has simultaneously tested the relationship between coping style, adrenocortical reactivity and oxidative status in the same individuals. We measured individual variation in coping styles along a proactive-reactive continuum together with variation in baseline and stress-induced plasma oxidative damage, plasma non-enzymatic antioxidant capacity and cortisol in wild alpine marmots, Marmota marmota. Confirmatory path analysis revealed that different coping styles are accompanied by different baseline and stress-induced plasma oxidative statuses. Our findings also highlight the potential role of cortisol as a mediator of such differences.

PURPOSE: We aimed to assess the association between features of epicardial adipose tissue and demographic, morphometric and clinical data, in a large population of symptomatic patients with clinical indication to cardiac computed tomography (CT) angiography. METHODS: Epicardial fat volume (EFV) and adipose CT density of 1379 patients undergoing cardiac CT angiography (918 men, 66.6%; age range, 18-93 years; median age, 64 years) were semi-automatically quantified. Clinical variables were compared between diabetic and nondiabetic patients to assess potential differences in EFV and adipose CT density. Multiple regression models were calculated to find the clinical variables with a significant association with EFV and adipose CT density. RESULTS: The median EFV in diabetic patients (112.87 mL) was higher compared with nondiabetic patients (82.62 mL; P < 0.001). The explanatory model of the multivariable analysis showed the strongest associations between EFV and BMI (ß=0.442) and age (ß=0.365). Significant yet minor association was found with sex (ß=0.203), arterial hypertension (ß=0.072), active smoking (ß=0.068), diabetes (ß=0.068), hypercholesterolemia (ß=0.046) and cardiac height (ß=0.118). The mean density of epicardial adipose tissue was associated with BMI (ß=0.384), age (ß=0.105), smoking (ß=0.088), and diabetes (ß=0.085). CONCLUSION: In a large population of symptomatic patients, EFV is higher in diabetic patients compared with nondiabetic patients. Clinical variables are associated with quantitative features of epicardial fat.

Alpine marmots Marmota marmota occupy a narrow altitudinal niche within high elevation alpine environments. For animals living at such high elevations where resources are limited, parasitism represents a potential major cost in life history. Using occupancy models, we tested if marmots living at higher elevation have a reduced risk of being infected with gastro-intestinal helminths, possibly compensating the lower availability of resources (shorter feeding season, longer snow cover and lower temperature) than marmots inhabiting lower elevations. Detection probability of eggs and oncospheres of two gastro-intestinal helminthic parasites, Ascaris laevis and Ctenotaenia marmotae, sampled in marmot feces, was used as a proxy of parasite abundance. As predicted, the models showed a negative relationship between elevation and parasite detectability (i.e. abundance) for both species, while there appeared to be a negative effect of solar radiance only for C. marmotae. Site-occupancy models are used here for the first time to model the constrains of gastrointestinal parasitism on a wild species and the relationship existing between endoparasites and environmental factors in a population of free-living animals. The results of this study suggest the future use of site-occupancy models as a viable tool to account for parasite imperfect detection in eco-parasitological studies, and give useful insights to further investigate the hypothesis of the contribution of parasite infection in constraining the altitudinal niche of Alpine marmots.

Several personality traits are mainly expressed in a social context, and others, which are not restricted to a social context, can be affected by the social interactions with conspecifics. In this paper, we focus on the recently proposed hypothesis that social niche specialization (i.e. individuals in a population occupy different social roles) can explain the maintenance of individual differences in personality. We first present ecological and social niche specialization hypotheses. In particular, we show how niche specialization can be quantified and highlight the link between personality differences and social niche specialization. We then review some ecological factors (e.g. competition and environmental heterogeneity) and the social mechanisms (e.g. frequency-dependent, state-dependent and social awareness) that may be associated with the evolution of social niche specialization and personality differences. Finally, we present a conceptual model and methods to quantify the contribution of ecological factors and social mechanisms to the dynamics between personality and social roles. In doing so, we suggest a series of research objectives to help empirical advances in this research area. Throughout this paper, we highlight empirical studies of social niche specialization in mammals, where available.
