Background: In Italy, a nationwide full lockdown was declared between March and May 2020 to hinder the novel coronavirus disease 2019 (COVID-19) pandemic. The potential individual health effects of long-term isolation are largely unknown. The current study investigated the arrhythmic consequences of the COVID-19 lockdown in patients with defibrillators (ICDs) living in the province of Ferrara, Italy., Methods: Both the arrhythmias and the delivered ICD therapies as notified by the devices were prospectively collected during the lockdown period (P1) and compared to those occurred during the 10 weeks before the lockdown began (P2) and during the same period in 2019 (P3). Changes in outcome over the three study periods were evaluated for significance using McNemar's test., Results: A total of 413 patients were included in the analysis. No differences were found concerning either arrhythmias or shocks or anti-tachycardia pacing. Only the number of patients experiencing non-sustained ventricular tachycardias (NSVTs) during P1 significantly decreased as compared to P2 (p = 0.026) and P3 (p = 0.009). The subgroup analysis showed a significant decrease in NSVTs during P1 for men (vs. P2, p = 0.014; vs. P3, p = 0.040) and younger patients (vs. P2, p = 0.002; vs. P3, p = 0.040) and for ischemic etiology (vs. P2, p = 0.003). No arrhythmic deaths occurred during P1., Conclusions: The complete nationwide lockdown, as declared by the Italian government during the first COVID-19 pandemic peak, did not impact on the incidence of arrhythmias in an urban cohort of patients with ICDs., (© 2021 The Authors.

Aims: Inflammation-based scores such as neutrophil-lymphocyte ratio (NLR) and Onodera nutritional index (ONI) have been identified as new prognosticators in several tumors. We conducted a prognostic analysis of these markers and performed a risk stratification of PMP patients submitted to cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC)., Methods: 226 patients from two peritoneal surface malignancies centers participated in this study. Cox proportional modeling was used to select predictors of overall survival (OS) among baseline inflammation-based scores, serum tumor markers, clinical and surgical variables. Risk stratification was done using conditional inference tree model., Results: One hundred eighty-two cases had diffuse peritoneal adenomucinosis subtype. Fifty-four cases had received previous systemic chemotherapy. The means of ONI and NLR were 51.4 (SD = 9.8) and 3.2 (SD = 2.3), respectively. Two hundred ten cases were optimally cytoreduced. Cox analysis identified completeness of cytoreduction, histological subtype, previous systemic chemotherapy, NLR, and CA 19-9 as independent prognosticators. Conditional inference tree method identified two poor prognostic subsets: NLR ≤2.7 and CA 19-9>336 (5yr-OS = 15%) and NLR >2.7 and ONI ≤42 (5yr-OS = 30%)., Conclusions: NLR, ONI, and CA 19-9 are new prognosticators that contributed to improve prediction of OS in PMP patients treated by CRS and HIPEC. These markers allowed a risk stratification that could optimize therapeutic management of PMP patients., (Copyright © 2015 Elsevier Ltd. All rights reserved.)

Background: We assessed the learning curve (LC) of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in treating peritoneal surface malignancies (PSM) in two centers and evaluated in which extent surgical tutoring could abbreviate the learning process., Methods: Six hundred and forty-one cases submitted to CRS using peritonectomy procedures and HIPEC were considered. After having overcome its own LC, the NCI of Milan has provided technical assistance to Bentivoglio's centre for the development of a new PSM program since 2003. The risk-adjusted sequential probability ratio test (RA-SPRT) was employed to assess the LC of the two centers. Outcomes were incomplete cytoreduction, G3-5 morbidity (NCI-CTCAE.v3) and procedure-related mortality (PRM)., Results: Rates of incomplete cytoreduction, G3-5 morbidity, and PRM were 8.4%, 30.1%, and 3.9%, respectively, in the entire series. The breaking points of the LC concerning incomplete cytoreduction, G3-5 morbidity, and PRM were achieved at 141, 158, and 144 cases, in the Milan's experience, and at 126, 134, and 60 cases in the Bentivoglio's experience., Conclusions: Surgical tutoring could substantially shorten the steep LC associated with CRS and HIPEC. Our data should be confirmed by further studies on LC focusing oncological outcomes. Other factors that could influence the length of learning process should be identified., (Copyright © 2012 Wiley Periodicals, Inc.)

Aim: The present study was specifically designed to assess the major clinical and pathological variables of patients with colorectal peritoneal carcinomatosis in order to investigate whether currently used criteria appropriately select candidates for peritonectomy procedures (cytoreductive surgery) combined with hyperthermic intraperitoneal chemotherapy (HIPEC)., Patients and Methods: Preoperative, operative and follow-up data on 146 consecutive patients presenting with peritoneal carcinomatosis of colorectal origin and treated by surgical cytoreduction combined with HIPEC in 5 Italian Hospital and University Centers were prospectively entered in a common database. Univariate and multivariate analyses were used to assess the prognostic value of clinical and pathologic factors., Results: Over a minimum 24-month follow-up, the overall morbidity rate was 27.4% (mortality rate: 2.7%) and was directly related to the extent of surgery. Peritoneal cancer index (PCI), unfavorable peritoneal sites, synchronous or previously resected liver metastasis and the completeness of cytoreduction, all emerged as independent prognostic factors correlated with survival., Conclusions: Until research provides more effective criteria for selecting patients based upon the biomolecular features of carcinomatosis, patients should be selected according to the existing independent prognostic variables., (Copyright © 2010 Elsevier Ltd.
