ed concomitantly. Several cases of germline mosaicism have been reported to date, but their frequency is probably underestimated. Moreover, it is important to note that germline mosaicism cannot be ruled out by conventional cytogenetic screening of blood cells. This case highlights the need for close follow-up of every pregnancy obtained through gamete donation, given that the occurrence of germline mosaicism may have major consequences when multiple pregnancies are obtained concomitantly.Ferroptosis belongs to a novel form of regulated cell death. It is characterized by iron dependence, destruction of intracellular redox balance and non-apoptosis. And cellular structure and molecules level changes also occur abnormally during ferroptosis. It has been proved that ferroptosis exist widespreadly in many diseases, such as heart disease, brain damage or alzheimer disease. At the same time, the role of ferroptosis in cancer cannot be underestimated. More and more indications have told that ferroptosis is becoming a powerful weapon against cancer. In addition, therapies rely on ferroptosis have been applied to the clinic. Therefore, it is necessary to understand this newly discovered form of cell death and its connection with cancer. This review summarizes the mechanism of ferroptosis, ferroptosis inducers based on different targets and inspection methods. At last, we analyzed the relationship between ferroptosis and malignancies, in order to provide a novel theory basis for cancer treatment. As coronavirus disease 2019 (COVID-19) continues to spread globally, we aimed to describe and compare changes in the immune and cardiovascular systems of patients with mild versus severe COVID-19 at different time points during the course of disease. One hundred and one patients diagnosed with COVID-19 who underwent serial peripheral blood collection and chest computed tomography (CT) imaging were enrolled in this study and grouped by the severity of their illness. Changes in the immune and cardiovascular systems were analysed and compared between groups. The study included 43 women and 58 men, with a median age of 45years (interquartile range [IQR], 16-71). We identified spleen shrinkage in 27.7% of study patients. Ratios of spleen volume to patient (skin) volume were compared, with evidence that severe patients had more splenic shrinkage than mild patients. Lymphopenia was observed in 65.3% of patients, and 27.3% of patients had persistently low levels of lymphocytes after discharge. Tachycardia occurred mainly during the first 2days of hospitalisation, with increases in creatine kinase-myocardial band levels in 10 (9.9%) patients and arrhythmias in 16 (15.8%) patients. In addition to pulmonary manifestations, our study demonstrated that other organ systems can also be affected during COVID-19 infection, with evidence of immunosuppression and cardiovascular dysfunction, which may contribute to increased mortality rates in critically ill COVID-19 patients.

Aging is associated with altered immune function and chronic low-grade inflammation, referred to as immunosenescence. https://www.selleckchem.com/products/CP-690550.html As breast cancer is an age-related disease, the impact of aging on tumor immune responses may have important consequences. However, effects of immunosenescence on breast tumor immune infiltration remain largely unknown. This exploratory study investigated a broad panel of immune/senescence markers in peripheral blood and in the tumor microenvironment of young, middle-aged and old patients diagnosed with early invasive luminal (hormone-sensitive, HER2-negative) breast cancer. In the old group, G8-scores were computed as a correlate for clinical frailty. Significant age-related changes in plasma levels of several inflammatory mediators (IL-1α, IP-10, IL-8, MCP-1, CRP), immune checkpoint markers (Gal-9, sCD25, TIM-3, PD-L1), IGF-1 and circulating miRs (miR-18a, miR-19b, miR-20, miR-155, miR-195 and miR-326) were observed. Shifts were observed in distinct peripheral blood mononuclear cell populations, particularly naive CD8 T-cells. At the tumor level, aging was associated with lower total lymphocytic infiltration, together with decreased abundance of several immune cell markers, especially CD8. The relative fractions of cell subsets in the immune infiltrate were also altered. Clinical frailty was associated with higher frequencies of exhausted/senescent (CD27 CD28 and/or CD57 ) terminally differentiated CD8 cells in the blood and with increased tumor infiltration by FOXP3 cells. Aging and frailty are associated with profound changes of the blood and tumor immune profile in luminal breast cancer, pointing to a different interplay between tumor cells, immune cells and inflammatory mediators at higher age.

Global health education (GHE) is spreading in Europe and in other parts of the world. Since 2008, Sapienza University of Rome has offered activities to medical and other health profession students related to global health (GH), which is grounded in the theory of social determinants of health and inspired by social justice. The educational activities included elective courses as well as community and service-learning experiences, referred to as GH gyms. This study attempts to measure the long-term impact of these educational experiences, especially to demonstrate their influence on the perceived social responsibility of future health professionals. A questionnaire was elaborated and tested on a small sample of participants. It was sent to participants by e-mail. Quantitative results were analysed through descriptive statistics and qualitative answers were carefully read and classified. A total of 758 students from different faculties took part to the educational experiences. Only 488 e-mail addresses were available.
