Partendo da una difficoltà che è quella di dare un nome a dimensioni che non hanno chiara definizione, il testo introduce il lavoro di indagine e di progetto sviluppato durante e in seguito al Laboratorio del Cammino 2022. In questa occasione si sono attraversati i territori in contrazione delle province di Biella e Torino e lo sguardo è stato rivolto ai/alle pionieri/e (umani e non) capaci di abitare un territorio alle volte ostile ma ricco di nuove possibilità. Starting from the effort needed to name realities that have no clear definition, the contribution introduces the field research and project work developed during and after the "Laboratorio del Cammino", 2022. On this occasion, territories in contraction were crossed in the provinces of Biella and Turin and the gaze was turned to the pioneers (human and not-human) capable of inhabiting a territory that is sometimes hostile but full of new possibilities.

In the COVID-19 era, we designed the webinar "COVID-19: instructions for use" with the aim of providing clear and actionable information to school staff about the characteristics of the disease, the preventive measures to adopt and the path for early detection and control of COVID-19 in primary schools of Modena province.We performed a cross-sectional survey using a 7-item closed-ended satisfaction questionnaire self-administered to webinar participants among school staff of the Modena Municipality and neighbouring.A total of 103 out of 152 (68%) participants delivered the questionnaires. The participating staff came from 29 schools. Most of respondents (83.5%) were primary school teachers following by kindergarten teachers and educators. The overall webinar assessment index was "very good" for 51% of attendees and "good" for the remaining. Nevertheless, 25.2% highlighted the need to have more time dedicated to the discussion.Our project promotes a virtuous circle between school-family and community; so that the benefits can be sustained and enhanced. This may improve the effectiveness of the preventive measures in terms of transmission of SARS-CoV-2 and other virus.

Rhabdomyosarcoma (RMS) is a pediatric tumor, which arises from muscle precursor cells. Recently, it has been demonstrated that Hippo Pathway (Hpo), a pathway that regulates several physiological and biological features, is involved in RMS tumorigenesis. For instance, an upregulation of the Hpo downstream effector Yes-Associated Protein 1 (YAP) leads to the development of embryonal rhabdomyosarcoma (eRMS) in murine activated muscle satellite cells. On the other hand, the YAP paralog transcriptional co-activator with PDZ-binding motif (TAZ) is overexpressed in alveolar rhabdomyosarcoma (aRMS) patients with poor survival. YAP and TAZ exhibit both cytoplasmic and nuclear functions. In the nucleus, YAP binds TEADs (TEA domain family members) factors and together they constitute a complex that is able either to activate the transcription of several genes such as MYC, Tbx5 and PAX8 or to maintain the stability of others like p73. Due to the key role of YAP and TAZ in cancer, the identification and/or development of new compounds able to block their activity might be an effective antineoplastic strategy. Verteporfin (VP) is a molecule able to stop the formation of YAP/TEAD complex in the nucleus. The aim of this study is to evaluate the action of VP on RMS cell lines. This work shows that VP has an anti-proliferative activity on all RMS cell lines analyzed. Depending on RMS cell lines, VP affects cell cycle differently. Moreover, VP is able to decrease YAP protein levels, and to induce the activation of apoptosis mechanism through the cleavage of PARP-1. In addition, Annexin V assay showed the activation of apoptosis and necrosis after VP treatment. In summary, the ability of VP to disrupt RMS cell proliferation could be a novel and valuable strategy to improve the therapeutic approaches in treating rhabdomyosarcoma.

Obiettivi. Il selenio, micronutriente essenziale per l’uomo, sembra svolgere un ruolo protettivo nei confronti dell’insorgenza di malattie cronico-degenerative, in particolare del cancro, grazie alla sua attività antiossidante. La sorgente naturale di selenio è rappresentata dalla dieta e la sua concentrazione nei cibi dipende dalle caratteristiche geobotaniche dell’area di provenienza degli alimenti. Nell’ambito di uno studio sull’arricchimento delle uova con acidi grassi w3 e microelementi essenziali (Se e I), il nostro obiettivo era quello di verificare se la supplementazione con Se potesse realmente arricchire l’uovo con questo elemento contribuendo ad un miglioramento della qualità nutrizionale dell’uovo. Per confronto sono state esaminate uova presenti normalmente sul mercato. Metodi. La prova è stata condotta su sette gruppi di galline ovaiole, alimentate con un mangime di base solo o addizionato con I o Se o con entrambi i sali. Le uova commerciali sono state acquistate tenendo conto dei diversi sistemi di allevamento delle ovaiole. Risultati. Il Se si accumula prevalentemente nel tuorlo delle uova sia commerciali (1,04±0,28 mg/g) che trattate (da 1,60±0,21 a 1,98±0,16 mg/g, secondo il trattamento). La supplementazione con Se e ancora di più quella con Se + I si associava ad una riduzione del contenuto di Cd , in misura inferiore di Pb, e favoriva l’accumulo di acidi grassi w3. Tuttavia si è osservato una tendenza al calo di Zn nei prodotti supplementati.

A multicentric Italian investigation on legionnaires' disease is in course to clarify host factors as well as pathogen associated characteristics involved in the infection/disease. The main goal of the research plan is to account for some critical aspects concerning identification and prevention of legionellosis. To improve knowledge on factors associated with Legionella spp colonisation in hot waters, to detect cases and to characterize risk factors in subjects which develop pneumonia are specific objectives of the research programme. Preliminary results show that hot waters of houses and hotels are frequently contaminated (22.6% and 54.6%, respectively), mainly by L. pneumophila. Microbial concentrations were low in domestic waters (1.000 ufc/l), but higher in samples from the hotels (geom. mean 1.85 x 10(3) ufc/l). Warming system, age of the plant, type of building were risk factors significantly associated with Legionella spp positivity. The active surveillance on patients affected by pneumonia with search for Legionella urinary antigen allowed the identification of 34 cases, 3 of which of nosocomial origin, corresponding to 4.2% of the screened pneumonia. After informed consent, 26 subjects were recruited for a case-control-study to clarify risk factors for the disease.

The relationship between Legionella and Pseudomonas spp contamination and mineral content of domestic hot waters was investigated in a cross-sectional Italian survey. Pseudomonas spp contamination was associated with elevated Ca, but lower Fe and free chlorine content in the water. Waters with Cu concentrations50 microg/L prevented Legionella spp colonisation (OR = 0.14, 95% CI = 0.02-1.13), whereas the risk of legionellae occurrence increased in waters with Mn levels3 microg/L (OR = 2.37, 95% CI = 1.06-5.30). Furthermore, Mn was positively associated with the risk of colonisation by eterotrophic bacteria growing at either 22 and 36 degrees C. Legionella species and serogroups were differently distributed according to Cu and Mn concentrations, suggesting that Legionella strains may have a different sensibility/resistance to trace elements. A specific action of Cu as decontamination factor is suggested and the consideration of Mn as a risk indicator for bacterial colonisation and biofilm presence is proposed.

Tattooing and piercing may lead to health complications. The present multicenter cross-sectional study aimed to assess awareness and knowledge of health risks related to body art and to identify their possible determinants among a large sample of undergraduates in Italy. A web-based questionnaire collecting information on socio-demographic characteristics, awareness, knowledge, and some potential predictors was administered to undergraduates attending twelve Italian universities. The level of knowledge was expressed as the number of correct answers (0–11 for tattooing, 0–14 for piercing). A total of 2985 participants (mean age 23.15 ± 3.99, 73.9% F) participated in the study. Although 95.4% of the respondents were aware of possible health consequences of body art, a low level of specific knowledge was registered for both tattooing (mean number of correct answers 5.38 ± 2.39) and piercing (5.93 ± 3.12) consequences. Lower knowledge was associated with the attendance of non-life science course and with lower duration of academic education for both tattoo and piercing. Lower knowledge of tattooing risks was related with commuter status, while lower knowledge of piercing risks was associated with lower father’s education. These findings highlight the need to enhance information campaigns targeted to youths to increase their awareness of possible health risk of body art.

Background: tattooing and piercing are increasingly common, especially among youths. However, several health complications may be associated with these practices if basic hygiene rules are not respected. This multicenter study was aimed at exploring tattoo and piercing experiences reported by a large sample of Italian undergraduate students through a public health perspective. Methods: tattooed and/or pierced students attending 12 Italian universities were asked to complete a web-based questionnaire regarding their body art experience. Results: out of 1472 respondents, 833 (56.6%) were tattooed and 1009 (68.5%) were pierced. The greatest proportion of tattooed students (93.9%) got her/his first tattoo in a tattoo studio, while most of the pierced were serviced in a jewelry store (48.0%). The pierced ones were less informed on health issues related to the procedure (56.0% versus 77.8% of tattooed p < 0.001), and tattooists were reportedly more attentive to hygiene rules (instrument sterilization 91.5% versus 79.1% of piercers, p < 0.001; use of disposable gloves 98.2% versus 71% of piercers, p < 0.001). Conclusions: educational interventions for both professionals and communities are needed to improve the awareness and the control of health risks related to body art throughout the Italian territory.

A cross-sectional multicenter survey of Italian hotels was conducted to investigate Legionella spp. contamination of hot water. Chemical parameters (hardness, free chlorine concentration, and trace element concentrations), water systems, and building characteristics were evaluated to study risk factors for colonization. The hot water systems of Italian hotels were strongly colonized by Legionella ; 75% of the buildings examined and 60% of the water samples were contaminated, mainly at levels of ≥10 3 CFU liter −1 , and Legionella pneumophila was the most frequently isolated species (87%). L. pneumophila serogroup 1 was isolated from 45.8% of the contaminated sites and from 32.5% of the hotels examined. When a multivariate logistic model was used, only hotel age was associated with contamination, but the risk factors differed depending on the contaminating species and serogroup. Soft water with higher chlorine levels and higher temperatures were associated with L. pneumophila serogroup 1 colonization, whereas the opposite was observed for serogroups 2 to 14. In conclusion, Italian hotels, particularly those located in old buildings, represent a major source of risk for Legionnaires' disease due to the high frequency of Legionella contamination, high germ concentration, and major L. pneumophila serogroup 1 colonization. The possible role of chlorine in favoring the survival of Legionella species is discussed.

Objectives: The aim of this study was to analyze the consumption of dietary supplements (DSs) and related sociodemographic characteristics or behaviors in Italian undergraduates. Methods: A questionnaire-based, cross-sectional study was carried out between October 2021 and May 2022 involving undergraduates from 12 public universities. The use of DSs in the previous 6 mo, the aim and reason for use, the purchasing channel, and related adverse effects were explored and compared by sex. A logistic regression was performed to highlight possible associations between sociodemographic, anthropometric, and behavioral characteristics of participants and supplement consumption. Results: The use of DSs was reported by 71.5% of the 2165 respondents. Supplementation was related to sex (odds ratio [OR] 0.690; 95% confidence interval [CI], 0.516-0.924, for men), vegetarian or vegan (OR 4.814; 95% CI, 1.669-13.887) and other particular diet regimens (OR 1.819; 95% CI, 1.282-2.580), sport (OR 1.688; 95% CI, 1.116-2.553), and type of sport (OR 0.629; 95% CI, 0.423-0.936, for team sports). Women were more likely to use DSs following a doctor's prescription and to buy them in a pharmacy (P < 0.001) but reported more adverse effects (P=0.018) than men. The main aim pursued was general health; proteins, amino acids, and non-caffeinated energy supplements were consumed to improve physical performance and caffeinated energy supplements for mental performance. Conclusions: Diet supplementation was common in the sample examined, especially in women, and associated with particular dietary regimens and sports, especially individual sports. Female consumers follow specialists' indications more than males. These results highlight the need for educational interventions about diet supplementation for this category of users.
