In vivo immunomodulatory and antioxidant properties of nanoceria (nCeO2) in the marine mussel Mytilus galloprovincialis

Cerium nanoparticles (nCeO2) are increasingly utilized in a wide variety of industrial, environmental and biomedical applications, and are therefore expected to be released in the aquatic environment. Due to its peculiar redox properties, nCeO2 may present unique hazards to environmental and human health. Previous data showed that in the hemocytes of the marine bivalve Mytilus galloprovincialis, in vitro exposure to a particular type of nCeO2 (9 nm, characterized by negative ζ-potential, high H2O2 scavenging capacity and Ce3+/Ce4+ surface ratio) reduced basal ROS production, lysosomal membrane stability and phagocytic activity in the presence of hemolymph serum; the effects observed were partly ascribed to the formation of a SOD-protein corona in the hemolymph. In this work, the in vivo effects of this type of nCeO2 were investigated in mussels exposed to 100 μg/L nCeO2 for 96 h; several lysosomal, immune, inflammatory and antioxidant biomarkers were measured at cellular (hemocytes) and tissue (gills, digestive gland) level. Molecular responses were evaluated in hemocytes and digestive gland by determining expression of 11 selected genes related to known biological functions. The results show specific immunomodulatory and antioxidant effects of nCeO2 at different levels of biological organization in the absence of Cerium tissue accumulation. These data further support the redox mechanisms at the basis of the physiological effects of nCeO2. Finally, in order to evaluate the possible impact at the whole organism level, the effects of nCeO2 were evaluated in the 48 h embryotoxicity assay in a wide concentration range. However, nCeO2 exposure resulted in a small reduction in normal embryo development. Overall, the results demonstrate that in mussels nCeO2 can selectively modulate different physiological processes at different levels of biological organization

Healthcare Professional Communication on Sexual Health: A Report from the Italian Working Group on Adolescents and Young Adults with Cancer

Background: Sexual function is an important concern for adolescent and young adult (AYA) with cancer. The aim of this study was to explore the attitude of Italian health care professionals who deal with AYA patients with cancer toward sexual health communication. Materials and methods: A 11-question survey was developed by the AIOM (Associazione Italiana di Oncologia Medica) and AIEOP (Associazione Italiana Ematologia Oncologia Pediatrica) AYA workgroup and sent to AIOM and AIEOP members. Results: The sample comprised 360 respondents, 54.2% AIEOP and 45.8% AIOM members. Eighty percent were physicians, 14.5% nurses, 4.7% psychologists, and 0.8% other professionals. Medical oncologists are more used to investigate about AYA sexual health than pediatric oncologists (58.2% vs. 46.2%), even if pediatrics more frequently refer patients to specific and shared protocol (40% vs. 26.1%). Both AIOM and AIEOP participants mostly talk about sexual health only on request or occasionally (78.8% and 79%, respectively). Clinician-reported barriers to communication identified in this study are lack of preparation and embarrassment for both the categories, plus the presence/interference of parents for pediatrics and lack of time for medical oncologists. Overall, less than 5% of clinicians in our survey received specific training on potential sexual health issues in AYA patients with cancer and only 2% felt adequately prepared to speak about it. Conclusion: Sexual health is a key component of comprehensive care for AYA with cancer during treatments. This study highlighted the need of Italian providers for specific training and guidelines on sex-related health issues encountered by AYA patients

Supportive Care During Pediatric Hematopoietic Stem Cell Transplantation : Prevention of Infections. A Report From Workshops on Supportive Care of the Paediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT)

Specific protocols define eligibility, conditioning, donor selection, graft composition and prophylaxis of graft vs. host disease for children and young adults undergoing hematopoietic stem cell transplant (HSCT). However, international protocols rarely, if ever, detail supportive care, including pharmaceutical infection prophylaxis, physical protection with face masks and cohort isolation or food restrictions. Supportive care suffers from a lack of scientific evidence and implementation of practices in the transplant centers brings extensive restrictions to the child's and family's daily life after HSCT. Therefore, the Board of the Pediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT) held a series of dedicated workshops since 2017 with the aim of initiating the production of a set of minimal recommendations. The present paper describes the consensus reached within the field of infection prophylaxis.Peer reviewe

The Impact of Long-Term Exposure to Space Environment on Adult Mammalian Organisms: A Study on Mouse Thyroid and Testis

Hormonal changes in humans during spaceflight have been demonstrated but the underlying mechanisms are still unknown. To clarify this point thyroid and testis/epididymis, both regulated by anterior pituitary gland, have been analyzed on long-term space-exposed male C57BL/10 mice, either wild type or pleiotrophin transgenic, overexpressing osteoblast stimulating factor-1. Glands were submitted to morphological and functional analysis

Gestione dell’epidemia Covid-19 nei centri di oncoematologia pediatrica Italiani: survey nazionale AIEOP condotta da infermieri

INTRODUZIONE: la pandemia COVID-19 sta causando un'emergenza sanitaria globale. I sistemi sanitari sono sottoposti a pressioni estreme a causa dell'epidemia. La popolazione pediatrica sembra essere meno incline a sviluppare un decorso grave della malattia. Tuttavia, le informazioni sull'infezione COVID-19 e sui bambini affetti da cancro sono poche OBIETTIVO: Questo sondaggio ha lo scopo di evidenziare le misure preventive e di controllo per la gestione dell'infezione COVID-19 nei centri AIEOP (Associazione Italiana Ematologia ed Oncologia Pediatrica). METODO: È stato realizzato un sondaggio multicentrico e descrittivo. Tutti i centri AIEOP sono stati invitati a completare un sondaggio online. La raccolta dei dati è stata effettuata tra il 15 marzo 2020 e il 15 aprile 2020. RISULTATI: Trentasei centri su 48 hanno risposto al sondaggio. Tutti i centri hanno implementato misure preventive simili al fine di controllare la diffusione di COVID-19 e il 77,8% dei centri ha creato percorsi strutturati, protocolli o procedure specifici; Il 30% dei centri ha ridotto il numero di letti di degenza e il 90% di attività ambulatoriale. I dati sulla prevalenza raccolti riportano 14 bambini positivi e 35 operatori sanitari positivi. DISCUSSIONE: COVID-19 non si sta diffondendo in modo omogeneo in Italia e i bambini sono meno infetti. Sarà necessario definire nuovi processi e nuove strategie per garantire la sicurezza e la continuità delle cure ai bambini affetti da cancro, anche in futuro, quando terminerà il blocco e saranno implementate nuove misure.  INTRODUCTION: The COVID-19 pandemic is causing a global health emergency. Health systems are under extreme pressure because of the outbreak. Pediatric population seems to be less prone to develop a severe course of the disease. Still the information about COVID-19 infection and children affected by cancer are few. OBJECTIVE/AIM: This survey aims to highlight preventive and control measures to manage COVID-19 infection in Italian Pediatric Oncology and Hematology Association (AIEOP) centers. METHODS: A multicenter, descriptive survey design was used. All the AIEOP centers were invited to complete an on-line survey. Data collection was performed between March 15, 2020 and April 15, 2020. RESULTS: Thirty six out of 48 centers responded to the survey. All the centers implemented similar preventive measures in order to control the COVID-19 spread and 77.8% of centers have created structured pathways, specific protocols or procedures; 30% of centers reduced the number of inpatient beds and 90% outpatient activity. The prevalence data collected report 14 children positive and 35 healthcare professionals positive. DISCUSSION: COVID-19 is not spreading homogeneously in Italy and children are less infected. It will be necessary to define new processes and new strategies to ensure safety and continuity of care to children affected by cancer, even in the future, when the lockdown will end, and new measures will be implemented
