Highlights During a sudden and unprecedented event, such as the current pandemic, healthcare workers may be inadequately prepared and supported to cope with stressors and this negatively affected working environment. For healthcare professionals, a positive attitude towards the stressful situation was the main protective factor, while female gender, seeking social support, avoidance strategies and working with COVIDCOVID-19 patients were risk factors. It is important to investigate the response of healthcare professionals to the COVID-19 pandemic, in terms of perceived stress and coping strategies, in order to implement targeted prevention and intervention programs.

Emergency situations have been associated with negative psychological adjustment outcomes in healthcare professionals, although studies on the impact of the Coronavirus Disease 2019 (COVID-19) pandemic amongst Italian health workers are limited. The main aim of this study was to investigate the psychological adjustment of healthcare professionals during the peak of the COVID-19 pandemic, evaluating differences according to working or not with patients affected by COVID-19 and in areas with a more severe spread of this pandemic. Healthcare professionals’ attitudes toward psychological support were analyzed. The levels of anxiety, depression, psychological stress, and professional quality of life (compassion satisfaction, burnout, and compassion fatigue) and attitudes toward psychological support were measured among 627 Italian healthcare workers (mean age = 40.55 years; SD = 11.49; range: 27–72). Significantly higher levels of stress, burnout, secondary trauma, anxiety, and depression were observed among professionals working with COVID-19 patients. Higher levels of stress and burnout and lower levels of compassion satisfaction were detected in professionals working in areas with higher rates of contagion. No interaction effects were found between working (or not) with patients affected by COVID-19 and working (or not) in areas with a more severe diffusion of this pandemic. Finally, in the group of professionals who worked with COVID-19 patients, the percentage of professionals who thought to ask for psychological support was twice that of the group that did not work with COVID-19 patients. The overall findings indicate that the mental health of frontline healthcare workers requires further consideration and that targeted prevention and intervention programs are necessary.

Objective. Defective circulating dendritic cells (DCs) have been described in systemic lupus erythematosus (SLE) and correlated with high levels of interferon-␣ (IFN␣). DCs are differentiated as being either myeloid or plasmacytoid, according to chemokine expression and the tendency to migrate toward inflamed tissue. We investigated the potential role of interleukin-18 (IL-18) in driving the glomerular migration of DCs in lupus nephritis (LN) and in affecting the ability of DCs to induce an imbalance in the Th1:Th2 ratio.Methods. DC subsets were characterized by flow cytometry and defined as either myeloid or plasmacytoid according to the expression of CD11c/blood dendritic cell antigen 1 (BDCA-1) and CD123/BDCA-2, respectively. The serum Th1:

Having a baby while on dialysis is rare but not impossible, though early mortality remains high. There is a 'scale of probability' estimating that women on dialysis have a 10-fold lower probability of delivering a live-born baby than those who have undergone renal transplantation, who in turn have a 10-fold lower probability of delivering a live-born baby as compared with the overall population.

SummaryImbalance of cytokine homeostasis is a prominent feature of both experimental and human systemic lupus erythematosus (SLE). Because interleukin (IL)-12 promotes interferon (IFN)-g production leading to polarization of peripheral cells toward a T helper (Th) 1 phenotype, we investigated its role in lupus nephritis (LN). Soluble Th1 and Th2 cytokines were measured by enzyme-linked immunosorbent assay (ELISA) in sera and urines of SLE patients and controls. Th1/Th2 peripheral lymphocyte polarization was determined by flow cytometry. Glomerular accumulation of IL-12 was evaluated by immunohistochemistry, whereas urinary IL-12 was evaluated by ELISA. Higher serum IL-12 levels in SLE were associated with LN, whereas IL-4 was unrelated to the renal damage. Peripheral cells from LN patients showed a Th1 phenotype with a high IFN-g expression that paralleled the severity of renal damage. IL-12 was present within glomerular mononuclear cells in classes IV and V LN, and its accumulation was correlated strongly with urinary levels. IL-12 overexpression in SLE may contribute to the development of LN. Both serum and urinary IL-12 elevation reflect its glomerular production and parallel Th1 polarization of peripheral T cells and high IFN-g production. In SLE patients, IL-12 measurement may thus be predictive of the development of LN.
