Ferroptosis, a novel type of programmed cell death, is involved in inflammation and oxidation of various human diseases, including diabetic kidney disease. The present study explored the role of high-mobility group box-1 (HMGB1) on the regulation of ferroptosis in mesangial cells in response to high glucose. Compared with healthy control, levels of serum ferritin, lactate dehydrogenase (LDH), reactive oxygen species (ROS), malonaldehyde (MDA), and HMGB1 were significantly elevated in diabetic nephropathy (DN) patients, accompanied with deregulated ferroptosis-related molecules, including long-chain acyl-CoA synthetase 4 (ACSL4), prostaglandin-endoperoxide synthase 2 (PTGS2), NADPH oxidase 1 (NOX1), and glutathione peroxidase 4 (GPX4). In vitro assay revealed that erastin and high glucose both induced ferroptosis in mesangial cells. Suppression of HMGB1 restored cellular proliferation, prevented ROS and LDH generation, decreased ACSL4, PTGS2, and NOX1, and increased GPX4 levels in mesangial cells. Furthermore, nuclear factor E2-related factor 2 (Nrf2) was decreased in DN patients and high glucose-mediated translocation of HMGB1 in mesangial cells. Knockdown of HMGB1 suppressed high glucose-induced activation of TLR4/NF-κB axis and promoted Nrf2 expression as well as its downstream targets including HO-1, NQO-1, GCLC, and GCLM. Collectively, these findings suggest that HMGB1 regulates glucose-induced ferroptosis via Nrf2 pathway in mesangial cells.

The hard-to-reach populations, including the homeless, are particularly vulnerable to the development of active tuberculosis. According to the World Health Organization, tuberculosis rates among the homeless in industrialized Countries are up to 20 times higher if compared with the general popula-tion, representing a relevant public health problem. The aim of our study was to describe the results of an active tuberculosis screening applied in order to find out suspected active TB cases among the homeless in Verona.

As part of a partnership between the non-profit association Medici per la Pace and one of the Local Health Units of Veneto Region (ULSS 9 Scaligera) in 2018, a tuberculosis screening, based on thoracic radiographs, was offered to the homeless guests of two Verona's soup kitchens.

The studied population included 139 people, and three cases of suspected active tuberculosis, all in males, were observed. Among these, two received a diagnostic confirmation of active tuberculosis (a prevalence of 1.44% - CI 0,17 - 5,1). Moreover, radiographic patterns of tuberculosis aftermaths were found in six additional subjects.

Interventions specifically dedicated to hard-to-reach populations, can be useful in identifying tuberculosis active cases and controlling the disease in low tuberculosis burden countries. In particular, the active research of subjects, the screening carried out with mobile X-ray, and also the constant caring of the patients with active disease, could be the right method to keep under control this relevant public health problem.

The Coronavirus Disease 2019 pandemic has posed incredible challenges to healthcare workers worldwide. The residents have been affected by an almost complete upheaval of the previous setting of activities, with a near total focus on service during the peak of the emergency. In our Institution, residents in public health were extensively involved in leading activities in the management of Coronavirus Disease 2019 pandemic.

We hereby provide a systematic description of the response actions in which the public health residents' workforce was pivotal, in a large tertiary hospital.

The key role played by residents in the response to Coronavirus Disease 2019 pandemic is highlighted by the diversity of contributions provided, from cooperation in the rearrangement of hospital paths for continuity of care, to establishing and running new services to support healthcare professionals. Overall, they constituted a workforce that turned essential in governing efficiently such a complex scenario.

Despite the difficulties posed by the contingency and the sacrifice of many training activities, Coronavirus Disease 2019 pandemic turned out to be a unique opportunity of learning and measuring one's capabilities and limits in a context of absolute novelty and uncertainty.

To date, it is unknown how many Italians have had or have a mild SARS-CoV-2 infection, because of the lack of epidemiological studies involving the general population.

Aim of this study was to investigate the prevalence/incidence of a symptoms-based mild SARS-CoV-2 infection in southern Tuscany, by using an online survey.

An anonymous random middle-aged sample of 3,460 individuals completed the survey. A symptom-score ≥5, calculated on 195 patients with RT-PCR COVID-19 disease (sensitivity/specificity of 0.815/0.780 respectively) was used for the diagnosis.

This cut-off highlighted that 12.3% of all the population might have had a SARS-CoV-2 infection, while 3.9% of them might have it at the time of the survey. Female sex (OR=1.334 [1.029-1.728]; p=0.030), obesity status (OR=1.961 [1.304-2.949]; p=0.001), asthma (OR=2.035 [1.433-2.890]; p=0.0001), autoimmune diseases (OR=2.103 [1.381-3.201]; p=0.001), were all risk factors for showing mild SARS-CoV-2 infection. Instead, the elderly had a low probability to develop mild forms of the disease (OR=0.984 [0.975-0.994]; p=0.001). Symptoms scores might be used to screen subjects with a suspected infection. Female sex, obesity, asthma, autoimmune diseases may be factors linked with mild forms of COVID-19 disease.
