The impact of biologic therapy for moderate-to-severe psoriasis on the immune responses to SARS-CoV2 infection and vaccination

Dear Editor, we explored the impact of biologics and conventional therapies for psoriasis on humoral and T-cellular responses to SARS-CoV-2 infection and vaccine. The study (EUDRA 2020-004965-37 Humanitas ICH Ethic Committee) was conducted at the Istituto Clinico Humanitas-Rozzano, Milan, and at the University of Verona, Italy. The enrolled patients were affected by moderate-to-severe psoriasis and were divided into two groups: those who had developed COVID-19 infection (group 1, n=95) and those who underwent COVID-19 vaccination (group 2, n=77

Surgical Management of Indeterminate Thyroid Nodules across Different World Regions: Results from a Retrospective Multicentric (the MAIN-NODE) Study

Indeterminate thyroid nodules (ITNs) are characterized by an expected malignancy ranging from 5% to 30%, with most patients undergoing a diagnostic, rather than therapeutic, operation. The aim of our study was to compare the approach to ITNs across different regions of the world. In this retrospective, multicentric, international study, according to the WHO classification, we identified the South East Asian Region (SEAR), the Americas Region (AMR), the Eastern Mediterranean Region (EMR), the Europe Region (EUR), and the Western Pacific Region (WPR). One high-volume thyroid centre was included for each region. Demographic, preoperative, and pathologic data were compared among the different regions. Overall, 5737 patients from five high-volume thyroid centres were included in this study. We found that the proportion of ITNs over the global activity for thyroid disease was higher in the EUR (37.6%) than in the other regions (21.1-23.6%). In the EMR, the patients were significantly younger (with a mean of 43.1 years) than in the other regions (range, 48.8-57.4 years). The proportion of lobectomy was significantly higher in the WPR, where 83.2% (114/137) of patients received this treatment, than in the other regions, where lobectomies were performed in 44.1-58.1% of patients. The pathological diagnosis of malignancy was significantly higher in the SEAR centre, being over 60%, than in centres of the other regions, where it ranged from 26.3% to 41.3%. The occurrence of lymph node metastases was higher in the WPR (27.8%), AMR (26.9%), and EMR (20%) centres than in the EUR and SEAR centres, where it was lower than 10%. In summary, we found in our study different approaches and outcomes in the diagnosis and treatment of ITNs among countries. Overall, almost 60% of patients with ITNs who underwent surgery actually presented a benign disease, potentially undergoing an unnecessary operation

The e-learning platform of the FP7-SOPHIA Project: obtanied results and perspective for its future exploitation

FP7-SOPHIA, the European PV Research Infrastructure project coordinated by CEA-INES ended on 31st of January 2015. The project focused on strengthening and optimising the research capabilities of outstanding European Research Infrastructures by pulling together numerous scientists and researchers of more than 48 relevant Research Infrastructures to share a common vision and to conduct efficient and coordinated research work in the field of PV technologies. SOPHi@Webinar is the internal e-learning platform that has organized a set of online courses/seminaries/guest lectures in parallel to more conventional training initiatives held physically. It has also been opened to non-SOPHIA members

Immunopathological signatures in multisystem inflammatory syndrome in children and pediatric COVID-19

: Pediatric Coronavirus Disease 2019 (pCOVID-19) is rarely severe; however, a minority of children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) might develop multisystem inflammatory syndrome in children (MIS-C), with substantial morbidity. In this longitudinal multi-institutional study, we applied multi-omics (analysis of soluble biomarkers, proteomics, single-cell gene expression and immune repertoire analysis) to profile children with COVID-19 (n = 110) and MIS-C (n = 76), along with pediatric healthy controls (pHCs; n = 76). pCOVID-19 was characterized by robust type I interferon (IFN) responses, whereas prominent type II IFN-dependent and NF-κB-dependent signatures, matrisome activation and increased levels of circulating spike protein were detected in MIS-C, with no correlation with SARS-CoV-2 PCR status around the time of admission. Transient expansion of TRBV11-2 T cell clonotypes in MIS-C was associated with signatures of inflammation and T cell activation. The association of MIS-C with the combination of HLA A*02, B*35 and C*04 alleles suggests genetic susceptibility. MIS-C B cells showed higher mutation load than pCOVID-19 and pHC. These results identify distinct immunopathological signatures in pCOVID-19 and MIS-C that might help better define the pathophysiology of these disorders and guide therapy

Clinical features and outcomes of elderly hospitalised patients with chronic obstructive pulmonary disease, heart failure or both

Background and objective: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) mutually increase the risk of being present in the same patient, especially if older. Whether or not this coexistence may be associated with a worse prognosis is debated. Therefore, employing data derived from the REPOSI register, we evaluated the clinical features and outcomes in a population of elderly patients admitted to internal medicine wards and having COPD, HF or COPD + HF. Methods: We measured socio-demographic and anthropometric characteristics, severity and prevalence of comorbidities, clinical and laboratory features during hospitalization, mood disorders, functional independence, drug prescriptions and discharge destination. The primary study outcome was the risk of death. Results: We considered 2,343 elderly hospitalized patients (median age 81 years), of whom 1,154 (49%) had COPD, 813 (35%) HF, and 376 (16%) COPD + HF. Patients with COPD + HF had different characteristics than those with COPD or HF, such as a higher prevalence of previous hospitalizations, comorbidities (especially chronic kidney disease), higher respiratory rate at admission and number of prescribed drugs. Patients with COPD + HF (hazard ratio HR 1.74, 95% confidence intervals CI 1.16-2.61) and patients with dementia (HR 1.75, 95% CI 1.06-2.90) had a higher risk of death at one year. The Kaplan-Meier curves showed a higher mortality risk in the group of patients with COPD + HF for all causes (p = 0.010), respiratory causes (p = 0.006), cardiovascular causes (p = 0.046) and respiratory plus cardiovascular causes (p = 0.009). Conclusion: In this real-life cohort of hospitalized elderly patients, the coexistence of COPD and HF significantly worsened prognosis at one year. This finding may help to better define the care needs of this population

Upadacitinib for the treatment of concomitant psoriasis and atopic dermatitis: a case series

Purpose: The overlap of psoriasis and atopic dermatitis (AD) is rare and treating moderate-to-severe cases can be challenging. Conventional immune-suppressive drugs cannot be used long-term, and no biological drugs are currently approved for treating both conditions. Method: We report the cases of four patients with overlapping features of both psoriasis and AD. Result: After being treated with several systemic drugs, including gold-standard treatments for both psoriasis and AD, they received upadacitinib 15 or 30 mg, achieving complete remission. Upadacitinib is an inhibitor of Janus Kinase 1, currently approved for treating moderate-to-severe AD. Conclusion: To date, very limited data are available regarding the efficacy of upadacitinib in psoriasis. In a phase-3 trial on the efficacy of upadacitinib 15 mg in patients affected by psoriatic arthritis, 52.3% of patients achieved a 75% improvement in Psoriasis Area and Severity Index (PASI75) after one year. Currently, no clinical trials are evaluating the efficacy of upadacitinib in plaque psoriasis

Palladium supported on cross-linked imidazolium network on silica as highly sustainable catalysts for the Suzuki reaction under flow conditions

Highly cross-linked imidazolium-based materials,obtained by radical oligomerization of bisvinylimidazolium salts in the presence of 3-mercaptopropyl-modified silica gel, were used as supports for palladium catalysts. Thanks to the high imidazolium loading these materials were able to support a high amount of the metal (10 wt%). Such materials were characterized by several techniques (13C magic angle spinning nuclear magnetic resonance, the Brunauer\u2013 Emmett\u2013Teller technique, X-ray photoelectron spectroscopy, and transmission electron microscopy). The palladium catalysts displayed good activity allowing the synthesis of several biphenyl compounds in high yields working with only 0.1 mol% of palladium loading at 50 8C in ethanol/water under batch condition. Moreover, a flow apparatus, to optimize the efficiency of the isolation of the pure products and minimize waste (E-factor), was investigated. For the first time the palladium catalyst and base(K2CO3) were placed in two separate columns allowing an easy recovery of the products with very low E-factor values (<4). Waste production was reduced by over 99% compared to classic batch conditions. Because of the high Pd loading only 42 mg of catalysts were employed in the Suzuki reaction between 160 mmol of 4-bromotoluene and 180 mmol of phenylboronic acid. No loss in activity was observed
