Il divieto dei patti successori tra norma imperativa, profili di tutela dei legittimari e frode alla legge

Scopo dell’indagine è quello di verificare quale possa essere, nel tempo attuale, l’effettivo ambito di applicazione del divieto dei patti successori, alla luce di una sempre più avvertita spinta verso la "contrattualizzazione" della successione a causa di morte. A partire dalla genesi storica del divieto e sulla base di un'analisi separata delle tre diverse categorie di patti sulle successioni future, viene in particolare affrontato il problema, da sempre discusso, del fondamento giustificativo della norma contenuta nell'art. 458 c.c. L'ambito della indagine viene poi allargato, anche in chiave critica, alla ricerca di possibili punti di contatto tra il divieto in parola e altri fondamentali istituti: la c.d. legittima (e la tutela dei legittimari), da un lato, e la clausola generale della frode alla legge, dall'altro

Neutralizing antibodies to Omicron after the fourth SARS-CoV-2 mRNA vaccine dose in immunocompromised patients highlight the need of additional boosters

IntroductionImmunocompromised patients have been shown to have an impaired immune response to COVID-19 vaccines.MethodsHere we compared the B-cell, T-cell and neutralizing antibody response to WT and Omicron BA.2 SARS-CoV-2 virus after the fourth dose of mRNA COVID-19 vaccines in patients with hematological malignancies (HM, n=71), solid tumors (ST, n=39) and immune-rheumatological (IR, n=25) diseases. The humoral and T-cell responses to SARS-CoV-2 vaccination were analyzed by quantifying the anti-RBD antibodies, their neutralization activity and the IFN-γ released after spike specific stimulation.ResultsWe show that the T-cell response is similarly boosted by the fourth dose across the different subgroups, while the antibody response is improved only in patients not receiving B-cell targeted therapies, independent on the pathology. However, 9% of patients with anti-RBD antibodies did not have neutralizing antibodies to either virus variants, while an additional 5.7% did not have neutralizing antibodies to Omicron BA.2, making these patients particularly vulnerable to SARS-CoV-2 infection. The increment of neutralizing antibodies was very similar towards Omicron BA.2 and WT virus after the third or fourth dose of vaccine, suggesting that there is no preferential skewing towards either virus variant with the booster dose. The only limited step is the amount of antibodies that are elicited after vaccination, thus increasing the probability of developing neutralizing antibodies to both variants of virus.DiscussionThese data support the recommendation of additional booster doses in frail patients to enhance the development of a B-cell response directed against Omicron and/or to enhance the T-cell response in patients treated with anti-CD20

Prognostic Value of Amniotic Fluid Viral Load to Predict Adverse Outcome in Pregnancies Complicated by Congenital Cytomegalovirus Infection: A Multicenter Study

Introduction: To report the prognostic value of Cytomegalovirus (CMV) viral load in the amniotic fluid (AF) in predicting the outcome of infected pregnancies.Methods: Multicenter retrospective study involving 11 Italian referral centers from 2012 to 2021. Inclusion criteria were fetuses with confirmed congenital CMV infection. The primary outcome was the prognostic value accuracy of CMV qPCR in AF in predicting the risk of additional anomalies detected either at follow-up ultrasound or fetal MRI. The secondary outcome was prediction of post-natal clinical symptoms related CMV infection. Multivariate logistic regression and area under the curve (AUC) analyses were used to analyze the data.Results: 104 fetuses were included. Associated anomalies detected at follow-up ultrasound or fetal MRI were detected in 14.4% of cases (15/104). Mean AF CMV viral load was significantly higher in fetuses with compared to those without additional anomalies at follow-up ultrasound or fetal MRI (3346634.27 +/- 402582.95 vs 761934 +/- 222513,2 p1310520 copies/ml, a sensitivity of 66.7% and a specificity of 84.3% a positive likelihood ratio of 4.24. Once excluding fetuses with anomalies at ultrasound or MRI, the diagnostic performance of qPCR in identifying fetuses with symptomatic infection after birth was low, with an AUC of 0.586,Conclusion: CMV viral load at second trimester amniocentesis has a moderate accuracy for the occurrence of CMV related anomalies in fetuses with congenital infection and normal ultrasound at the initial diagnosis. Conversely, prediction of symptomatic infection is low

Prenatal predictors of adverse perinatal outcome in congenital cytomegalovirus infection: a retrospective multicenter study

Objectives To identify predictors of adverse perinatal outcome in congenital cytomegalovirus (CMV) infection. Methods In a multicenter study fetuses with congenital CMV infection diagnosed by PCR on amniotic fluid and normal prenatal imaging at the time of diagnosis were included. Primary outcome was the occurrence of structural anomalies at follow-up ultrasound or prenatal magnetic resonance imaging (MRI). Secondary outcomes were the occurrence of anomalies detected exclusively postnatally and the rate of symptomatic infection. Results One hundred and four fetuses with congenital CMV were included in the study. Anomalies were detected at follow-up ultrasound or MRI in 18.3% (19/104) cases. Additional anomalies were found after birth in 11.9% (10/84) of cases and 15.5% (13/85) of newborns showed clinical symptoms related to CMV infection. There was no difference in either maternal age (p=0.3), trimester (p=0.4) of infection and prenatal therapy (p=0.4) between fetuses with or whiteout anomalies at follow-up. Conversely, median viral load in the amniotic fluid was higher in fetuses with additional anomalies at follow-up (p=0.02) compared to those without. At multivariate logistic regression analysis, high viral load in the amniotic fluid, defined as >= 100,000 copies/mL was the only independent predictor for the occurrence of anomalies detected exclusively at follow-up ultrasound assessment or MRI, with an OR of 3.12. Conclusions Viral load in the amniotic fluid is a strong predictor of adverse perinatal outcome in congenital CMV infection. The results of this study emphasize the importance of adequate follow up even in case of negative neurosonography to better predict postnatal adverse outcomes of infected newborns, especially in amniotic fluid high viral load

Oncoplastic and reconstructive surgery in SENONETWORK Italian breast centers: lights and shadows

: • Despite the significance of oncoplastic procedure, an italian database is lacking. • Senonetwork established a multidisciplinary survey to assess their safety and efficacy. • Reconstructive outcomes were positive across low and high-volume centers. • After mastectomy, implant-based techniques are common. DTI reconstruction is advantageuos. • This contributes to the global understanding of effective strategies against breast cancer

Practice of proctology among general surgery residents and young specialists in Italy: a snapshot survey

Anal diseases are very common and, in most of the cases, require surgery of minor or medium complexity, and, therefore, are among the most accessible diseases for surgeons in training. Aim of this study is to investigate the status of the training in proctology in Italy. A 31-items questionnaire was administered to residents and young specialists (<= 2 years) in general surgery, using mailing lists, and the social media accounts of the Italian Society of Colorectal Surgery. Answers from 338 respondents (53.8% males) were included in the final analysis. Overall, 252 respondents (74.5%) were residents and 86 (25.5%) young specialists. Two hundred and fifty-five (75.4%) respondents practiced proctology for the first time early on during their postgraduate training, but only 19.5% did it continuously for >= 24 months. Almost all respondents (334; 98.8%) had the chance to participate in proctological procedures, 205 (60.5%) as first surgeon. This percentage decreases according to the complexity of the surgery. In fact, only 11 (3.3%) and 24 (7.1%) of the respondents were allowed to be the first surgeon in more complex proctological diseases such as surgery for rectal prolapse and fecal incontinence. The present survey suggests that, in Italy, most surgeons in training deal with anal diseases. However, only few of them could achieve sufficient professional skills in the management of proctological diseases to be able to practice autonomously as young specialists
