Adherence to hormone therapy in patients with mCRPC: psychometric validation of the A-HT questionnaire.

Abstract: The incidence rate of prostate cancer (PCa) in many Western countries is high, contributing greatly to the cancer disease bur-den. In most cases, patients progress to metastatic disease defined as castration-resistant prostate cancer after androgen deprivation (mCRPC) following primary treatment where the majority of patients receive first-line new-generation oral hormonal therapies (HT) such as Abiraterone Acetate (AA) and Enzalutamide (ENZ). Despite the importance of correct intake of these drugs, adherence in patients with mCRPC is still poorly investigated and managed with measures not specific to this population. A self-report questionnaire was developed and validated with women with breast cancer treated with oral HT (A-BET). Therefore, this study aims to test the psychometric properties of this instrument on patients with mCRPC treated with AA or ENZ. A prospective observational validation study. The questionnaire was completed by all participants and again after 7/10 days by a randomized subsample to assess stability. Sixty-six patients completed the study (mean age of 72.8 years) and 31 completed the re-test (mean age of 72.7 years). Content validity reported excellent results. Cronbach's alpha of each item showed a strong correlation. Validation of an instrument to measure adherence to HT in patients with mCRPC can be a valuable tool for health professionals involved in patient care. In addition, having a population-specific validated instrument allows to make comparisons between results from different observations.

The onset of de novo autoantibodies in healthcare workers after mRNA based anti-SARS-CoV-2 vaccines: a single centre prospective follow-up study.

Nowadays, data concerning the risk of autoimmune disease after SARS-CoV-2 (COVID-19) vaccination is controversial. The aim of this single centre prospective follow-up study was to evaluate whether healthcare workers (HCWs) vaccinated with BNT162b2 mRNA and mRNA-1273 will show a development and/or a persistence of autoantibodies, focussing on the detection of antibodies against nuclear antigens (antinuclear antibodies, ANA). We enrolled 155 HCWs, however only 108 of them received the third dose and were considered for further analysis. Blood samples were collected before vaccine inoculation (T0), at 3 (T1) and 12 months (T2) after the first dose. All samples were analysed for the presence of a) ANA using indirect Immunofluorescence [IIF] (dilutions of 1:80, 1:160. 1:320 and 1:640), and anti-smooth muscle antibodies (ASMA); b) anti-myeloperoxidase (anti-MPO), anti-proteinase 3 (anti-PR3) and anti-citrullinated peptide antibodies (aCCP) [FEIA]; c) anti-phospholipid antibodies (anticardiolipin [aCL], anti-beta-2- glycoprotein I [anti-ß-2GPI] (Chemiluminescence). Line-blot technology was performed using the following kit: EUROLINE ANA profile 3 plus DFS70 (IgG). Our research suggests that mRNA based anti-SARSCoV-2 vaccines can induce the production of de novo ANA in 22/77(28,57%) of subjects and that the percentage of positivity seems to be directly correlated to the number of vaccine expositions: 6/77 (7,79%) after 2 doses; 16/77 (20,78%) after 3 doses. Since it is known that hyperstimulation of the immune system could lead to autoimmunity, these preliminary results seem to further sustain the idea that the hyperstimulation of the immune system might lead to an autoinflammatory mechanism and eventually to autoimmune disorders. However, the link between SARS-CoV-2 vaccination and the development of autoimmune diseases needs to be further investigated.

Human organ donation and spirituality: a multicentre observational study aimed at healthcare professionals who work in the Italian context.

Aim: This study aimed to assess if spirituality could be a predictor of organ donation, using a descriptive/knowledge survey aimed at healthcare professionals working in Italy. Methods: This multicentre, descriptive observational study was conducted in three Italian regions (Lombardy, Piedmont and Apulia). Two scales were used for the data collection: the Organ Donation Attitude Scale (ODAS) to explore the healthcare staff's attitudes towards organ donation and the Spiritual Health Life-Orientation Measure (SHALOM) to explore their perception of the concept of spirituality. Results: The sample included 688 healthcare professionals (460 females, 66.9%). The analysis of their attitudes, assessed as their predisposition to organ donation, evidenced the women's higher degree of agreement regarding the safety and effectiveness of the practice (40.7% versus 31.1%, p = 0.001). The sample showed a high positive attitude towards organ donation (M = 4.25, SD = 0.50), whereas the level of spirituality was slightly lower than the midpoint of the Likert scale (M = 2.76, SD = 1.31). Spirituality positively predicted the positive attitude towards organ donation among Lombard professionals with shorter (-1 SD) careers (b = 0.078, p = 0.044) and among both Piedmontese (b = 0.250, p < 0.001) and Apulian (b = 0.458, p < 0.001) professionals with longer (+1 SD) careers. Discussion: Regarding organ donation, the surveyed healthcare professionals showed higher scores in the positive attitude section and lower scores in the negative attitude section, regardless of the geographical context of reference.
