Il capitolo è la sintesi delle attività sviluppate all'interno del progetto CISAS per quanto attiene lo studio del microbioma umano e le influenze che l'ambiente può avere su di esso. Il capitolo fornisce al lettore numerosi spunti sulle relazioni tra microbioma e salute umana, tracciando i possibili scenari di sviluppo di tecnologie non invasive per lo studio delle comunità batteriche che popolano l'intestino umano.

Questo libro raccoglie i frutti di un'appassionata ricerca scientifica multidisciplinare dedicata agli effetti sull'ecosistema e sulle popolazioni dei fenomeni di degrado ambientale prodotti dalle attività umane. L'attenzione è centrata sui Siti di bonifica di Interesse Nazionale, dove l'inquinamento passato e attuale ha segnato la storia di ampi territori e delle comunità, che chiedono di conoscere e sempre più spesso sono disponibili a intervenire per contribuire a risolvere i problemi esistenti e a partecipare alle decisioni sul futuro. Il lettore troverà approfondimenti sugli studi che identificano le associazioni tra la presenza di contaminanti in aria, suolo, acque, alimenti e la salute delle popolazioni residenti. Si tratta di studi di geochimica, ecotossicologia, epidemiologia ambientale sulle popolazioni e sulle coppie madre-bambino, e molto altro. Vengono anche illustrate tecniche di campionamento e studi sperimentali promettenti, modelli statistici e matematici per l'interpretazione di dati complessi. Gli sforzi compiuti dalle discipline scientifiche ambientali, epidemiologiche e matematiche sono trattati in capitoli specifici e vengono collegati per spiegare come possono contribuire alle decisioni che riguardano le operazioni di bonifica, di protezione della salute e dell'ecosistema. Infatti, mentre la ricerca prosegue e si approfondisce, vanno identificate soluzioni per il risanamento dei territori e il costante monitoraggio della situazione e dei miglioramenti ottenuti. La comunicazione e la partecipazione dei cittadini vengono presentate come insieme di metodi e strumenti consolidati, che rendono possibile la condivisione delle decisioni sul destino sociale ed economico dei territori inquinati. Lo studio della relazione tra l'ambiente e la salute degli ecosistemi e delle comunità rappresenta il filo rosso di un'ampia ricerca in corso da cinque anni, cui hanno partecipato più di 150 ricercatori di numerosi Istituti del Consiglio Nazionale delle Ricerche, di Università, Agenzie ambientali e Istituzioni sanitarie, che proseguirà in sintonia con le richieste e le necessità di un periodo storico che chiede sempre maggiore attenzione alla cura, alla protezione, alla conservazione del patrimonio di natura, cultura e persone che compongono la nostra società.

The aim of this study is to assess the effect of contact time, contact distance and the use of personal protective equipment on the determination of SARS-CoV-2 infection in healthcare workers (HCWs). This study consists of an analysis of data gathered for safety reasons at the Sapienza Teaching Hospital Policlinico Umberto I in Rome through the surveillance system that was put into place after the worsening of the COVID-19 pandemic. The studied subjects consist of HCWs who were put under health surveillance, i.e., all employees who were in contact with subjects who were confirmed to have tested positive for SARS-CoV-2. The HCWs under surveillance were monitored for a period encompassing ten days after the date of contact, during which they undertook nasopharyngeal swab tests analysed through RT-PCR (RealStar® SARS-CoV-2 Altona Diagnostic–Germany). Descriptive and univariate analyses have been undertaken, considering the following as risk factors: (a) no personal protective equipment use (PPE), (b) Distance &lt, 1 m between the positive and contact persons, (c) contact time &gt, 15′. Finally, a Cox regression and an analysis of the level of synergism between factors, as specified by Rothman, were carried out. We analysed data from 1273 HCWs. Of these HCWs, 799 (62.8%) were females, with a sample average age of 47.8 years. Thirty-nine (3.1%) tested positive during surveillance. The overall incidence rate was 0.4 per 100 person-days. Time elapsed from the last exposure and a positive RT-PCR result ranged from 2 to 17 days (mean = 7, median = 6 days). In the univariate analysis, a distance &lt, 1 m and a contact time &gt, 15′ proved to be risk factors for the SARS-CoV-2 infection, with a hazard ratio (HR) of 2.62 (95% CI: 1.11–6.19) and 3.59 (95% IC: 1.57–8.21), respectively. The synergism analysis found the highest synergism between the “no PPE use” x “Contact time”. The synergy index S remains strongly positive also in the analysis of the factors “no PPE use” x “Distance” and “Time of contact” x “Distance”. This study confirms the absolute need to implement safety protocols during the pandemic and to use the correct PPE within health facilities in order to prevent SARS-CoV-2 infection. The analysis shows that among the factors considered (contact time and distance, no use of PPE), there is a strong synergistic effect.

Background Indoor allergens are risk factors for asthma: Thus, the characterization of indoor air quality is important for studying environment–health relationships in children. In particular, Dermatophagoides pteronyssinus is the dominant allergen for asthma. We cross-sectionally investigated the relationships among respiratory symptoms and function, airway inflammation, allergen sensitization, and indoor allergen concentration. Methods One hundred and thirty-two children aging 10-14 years and living in a Southern Mediterranean area were evaluated by parental questionnaires. Spirometry, exhaled nitric oxide (FeNO), skin prick tests, total, and specific serum IgE analyses were performed along with the evaluation of home dust samples for the content in Der p 1 allergen. Three clusters were created on the basis of the presence/absence of wheeze in the last 12 months (Wh12m) and Der p 1-specific IgE level. Results Cluster 1 (Wh12m+/high Der p 1 IgE) presented higher FeNO and poorer pulmonary function (lower FEV1 and FEF25%-75%), while its symptom score was not different from Cluster 2 (Wh12m+/low Der p 1 IgE). Cluster 3 (Wh12m−/low IgE) showed the lowest FeNO values and pulmonary function similar to Cluster 2. Within Cluster 1, both Der p 1-specific IgE and FeNO were positively correlated with dust Der p 1. Conclusions Similar asthma phenotypes may occur in children despite differences in their atopic state. In atopic children, sensitizing allergens in the indoor environment may increase airway inflammation worsening pulmonary function. Moreover, environmental exposures may contribute to the development of asthma-like symptoms also in the absence of atopic sensitization, thus contributing to asthma overdiagnosis.
