RESUMO
The present study aims to explore the prevalence of burnout characteristics and their association with resilience, coping strategies, and the intolerance of uncertainty dimensions. It also aims to explore the predictive effect of these variables on burnout dimensions, separately. Through the SurveyMonkey platform, 1,009 anaesthesiologists completed the Maslach Burnout Inventory (MBI), Resilience Scale, Intolerance of Uncertainty Scale Short Form (IU), and the Coping Inventory for Stressful Situations (CISS). According to the MBI cut-off, 39.7% and 25.8% of participants scored high in Emotional Exhaustion and Depersonalization, respectively, and 44.2% scored low in Personal Accomplishment. Several significant correlations between burnout dimensions and resilience, coping strategies, and the intolerance of uncertainty emerged. Regarding the linear regression models tested, coping strategies, resilience, and age showed a significant predictive effect on all three of the burnout dimensions. In conclusion, the results showed that individual levels of resilience and one's ability to tolerate uncertainty and task-oriented coping strategies represent significant factors for lower burnout levels in Italian anaesthesiologists during COVID-19 pandemic. These findings highlight the importance of intervention aimed at promoting useful coping strategies and enhancing resilience among healthcare workers.

The B.1.1.529 (omicron) variant has rapidly supplanted most other SARS-CoV-2 variants. Using microfluidics-based antibody affinity profiling (MAAP), we have recently shown that current therapeutic monoclonal antibodies exhibit a drastic loss of affinity against omicron. Here, we have characterized affinity and IgG concentration in the plasma of 39 individuals with multiple trajectories of SARS-CoV-2 infection and/or vaccination as well as in 2 subjects without vaccination or infection. Antibody affinity in patient plasma samples was similar against the wild-type, delta, and omicron variants (KA ranges: 122{+/-}155, 159{+/-}148, 211{+/-}307 M-1, respectively), indicating a surprisingly broad and mature cross-clade immune response. We then determined the antibody iso- and subtypes against multiple SARS-CoV-2 spike domains and nucleoprotein. Postinfectious and vaccinated subjects showed different profiles, with IgG3 (p = 0.002) but not IgG1, IgG2 or IgG4 subtypes against the spike ectodomain being more prominent in the former group. Lastly, we found that the ELISA titers against the wildtype, delta, and omicron RBD variants correlated linearly with measured IgG concentrations (R=0.72) but not with affinity (R=0.29). These findings suggest that the wild-type and delta spike proteins induce a polyclonal immune response capable of binding the omicron spike with similar affinity. Changes in titers were primarily driven by antibody concentration, suggesting that B-cell expansion, rather than affinity maturation, dominated the response after infection or vaccination.
RESUMO
Osteonecrosis of the jaw (ONJ) is commonly described as an adverse effect of the use of bisphosphonates. A few cases of ONJ associated with tyrosine kinase inhibitors (sunitinib, imatinib) have been reported in the literature and usually they occurred in patients simultaneously treated with bisphosphonates. We report an atypical case of ONJ related only to imatinib. A 72-year-old male patient was treated with imatinib for metastases from gastrointestinal stromal tumors (GISTs). The patient developed ONJ after 22 months of imatinib only therapy. During his whole life, the patient had never been treated with bisphosphonates or radiotherapy. Microscope examination of the tissues confirmed the clinical diagnosis of diffuse osteonecrosis and showed absence of neoplastic cells. Thus, secondary localisations from GISTs were ruled out. Osteonecrosis of the lower jaw appeared 22 months after initial and exclusive therapy with imatinib. Therefore, imatinib monotherapy can induce ONJ in patients that have never been treated with bisphosphonates or radiotherapy.

A woman contracted chickenpox in the 12th week of gestation. Her general practitioner and later the consultant obstetrician warned her about the small risk of giving birth to a disabled child. She decided to continue the pregnancy without undergoing invasive tests to diagnose fetal intrauterine infection. Symptoms of congenital varicella syndrome (CVS) were detected by ultrasound in the 29th and 34th weeks of gestation. On admission to hospital, the baby was not considered infectious and was not isolated because polymerase chain reaction analysis to detect varicella zoster virus (VZV) DNA in the blood, cerebrospinal fluid, saliva, skin scrapings and feces gave negative results. He was also not separated from his mother. The mother was without clinical complications. Varicella during pregnancy may result in VZV transmission to the fetus or newborn. Intrauterine VZV infection in the first 28 weeks of gestation may result in CVS with limb deformities, brain abnormalities and mental retardation. Usually the newborn is not infectious, and therapy and isolation are unnecessary. When the mother catches the infection in the second trimester, the newborn may manifest shingles in the first 2 years of life. A maternal rash erupting 5 days before to 2 days after delivery is frequently associated with clinically severe varicella in the newborn, leading to high mortality if untreated. Then the newborn is infectious and must be isolated. This case report underlines the need for expert medical counseling for women who contract chickenpox at any time during pregnancy. It also underlines the importance of immunizing susceptible women of childbearing age before they become pregnant.
