Lung infection named as COVID-19 is an infectious disease caused by the most recently discovered coronavirus 2 (SARS-CoV-2). CT (computed tomography) has been shown to have good sensitivity in comparison with RT-PCR, particularly in early stages. However, CT findings appear to not always be related to a certain clinical severity. The aim of this study is to evaluate a correlation between the percentage of lung parenchyma volume involved with COVID-19 infection (compared to the total lung volume) at baseline diagnosis and correlated to the patient’s clinical course (need for ventilator assistance and or death). All patients with suspected COVID-19 lung disease referred to our imaging department for Chest CT from 24 February to 6 April 2020were included in the study. Specific CT features were assessed including the amount of high attenuation areas (HAA) related to lung infection. HAA, defined as the percentage of lung parenchyma above a predefined threshold of −650 (HAA%, HAA/total lung volume), was automatically calculated using a dedicated segmentation software. Lung volumes and CT findings were correlated with patient’s clinical course. Logistic regressions were performed to assess the predictive value of clinical, inflammatory and CT parameters for the defined outcome. In the overall population we found an average infected lung volume of 31.4 ± 26.3% while in the subgroup of patients who needed ventilator assistance and who died as well as the patients who died without receiving ventilator assistance the volume of infected lung was significantly higher 41.4 ± 28.5 and 72.7 ± 36.2 (p < 0.001). In logistic regression analysis best predictors for ventilation and death were the presence of air bronchogram (p = 0.006), crazy paving (p = 0.007), peripheral distribution (p < 0.001), age (p = 0.002), fever at admission (p = 0.007), dyspnea (p = 0.002) and cardiovascular comorbidities (p < 0.001). In multivariable analysis, quantitative CT parameters and features added incremental predictive value beyond a model with only clinical parameters (area under the curve, 0.78 vs. 0.74, p = 0.02). Our study demonstrates that quantitative evaluation of lung volume involved by COVID-19 pneumonia helps to predict patient’s clinical course.

PurposeInflammatory markers, such as Lymphocyte-to-Monocyte Ratio (LMR), Neutrophil-to-Lymphocyte Ratio (NLR), and Platelet-to-Lymphocyte Ratio (PLR), have been shown to hold significant prognostic value in the context of head and neck cancer (HNC). Recently, delta inflammatory markers, the difference between pre and post- treatment inflammatory marker ratios, have been suggested as potentially significant values in predicting cancer prognosis. Our objective was to evaluate the prognostic utility of delta LMR, NLR, and PLR in head and neck squamous cell carcinoma (HNSCC).MethodsRetrospective cohort study in a tertiary academic hospital setting. Patients diagnosed with HNSCC in the oral cavity, larynx, and oropharynx treated with curative intent treatment were included. The variables collected were age, sex, BMI, alcohol/tobacco exposure, performance scores, ACE-27, tumor characteristics, adjuvant treatment, ECOG score, and lab values. Overall Survival (OS) and Event-Free Survival (EFS) were chosen as endpoints. OS was defined as time from date of treatment to date of last follow-up or death from any cause, and EFS was defined as the start of treatment to any progression, recurrence, or death from any cause. Univariate and multivariate analyses were performed on the primary endpoints.ResultsA total of 89 patients were included from 2010 to 2017. In multivariate analysis, EFS was found to be significantly associated with an N stage of 3 (p=0.0005) and delta LMR > -1.48 (p=0.0241). No significant relationships were uncovered with OS in multivariate analysis.ConclusionA higher delta LMR value (>-1.48) was associated with poorer EFS, but was not associated with OS.

Objective. Analysis of the initial surgical approach in patients with localized rhabdomyosarcoma, enrolled in Italian Studies (1979-2003). Methods. Surgical records of 587 patients were evaluated. As primary surgery, the excision was recommended if microscopically complete, otherwise biopsy was preferable. Results. The initial biopsy, performed in almost 50% of patients in RMS-79 protocol, has been adopted more often in the protocol RMS-88 and 96. However, the “complete resection” rate has remained quite stable through the years, as well as the percentage of microscopic residue. The macroscopic residue disease has been more important in RMS-88 study than in RMS-96. Most GUnBP tumors and about 10% of HNnPM and other site were successfully excised. A complete resection was rarely attempted in orbit, HNPM, and GUBP sites; regarding the extremities tumors, 62.5% of patients in RMS-79 study underwent a complete conservative excision, while most patients in RMS-88 and 96 underwent biopsy only. Conclusion. Initial surgical approach has become more conservative, avoiding mutilations, but the incomplete resection rate is still high. A satisfactory initial excision was obtained. in GUnBP RMS (mainly paratesticular). In other localizations the feasibility of a complete resection was slightly better for T1a RMS; a careful preoperative evaluation is always necessary.

Aim of the study was to evaluate the role of mutilating surgery in the patients with non chemosensitive soft tissue sarcomas (STS) registered in the Italian Studies. Between 1979 and 1995, 114 patients (pts) with "non chemosensitive" localized STS were enrolled in the cooperative studies RMS-79 (33) and RMS-88 (81). Median age: 89 months (range 1-194).fibrosarcoma 29, Malignant Perpheral Nerve Sheath Tumors (MPNST) 40, malignant fibrous histiocytoma 5, hemangiopericytoma 6, leiomyosarcoma 4, others 20, STS nos 10. The cases were classified according to the IRS staging system as Gr. I 46, Gr. II 24, Gr. III 44. Twelve out of 114 pts (7%), 5/33 (14%) in the first study and 7/81 (8%) in the second, underwent mutilating surgery: 8 pts (of whom 3 were2 y of age) had a fibrosarcoma and 4 a MPNST. The mutilating procedure was carried out at diagnosis in 6 cases (4 in RMS-79 and 2 in RMS-and 88) and achieved radicality in 5/6 cases. It was performed after ineffective chemotherapy (CT) in 5 pts (1 in RMS-79 and 4 in RMS-88). One pt (RMS-88) underwent mutilation after multiple local recurrences treated with CT, radiotherapy and conservative excisions (RMS-88) and died. The procedures consisted of 5 amputations, 4 demolitive excisions of extremities with functional impairment, 1 nephrectomy, 1 excision of deferents with spermatic vesicae and 1 mastectomy.At present 6/12 pts, 5 with fibrosarcoma and 1 with MPNST, are alive with no evidence of disease (NED), 4 of the first and 2 of the second study. Of the 5 Gr. I patients, 4 are alive (NED) and 1 died of 2nd tumor; 1 Gr. II pt is alive NED; of the 5 Gr. III pts 1 is alive NED and 4 died (3 of metastatic spread and 1 of 2nd tumor); the pt amputated after repeated local relapses (Gr. II) is dead of pulmonary metastases.In the RMS-79 study the mutilations were frequent and were performed at diagnosis in several cases; this trend decreased in the 2nd study in which chemotherapy was attempted in most of the patients. Probably the timing of mutilating procedures was not always adequate (too early or too late). The outcome of pts undergone mutilations is similar to that of the whole group of 114 pts, whose overall survival at 10 years is 64% (C.I. 60-77). Only fibrosarcomas and MPNST probably requires a more aggressive surgical behaviour. At present we avoid initial demolitive surgery; it should be planned without delay after the first local relapse or after initial ineffective CT and RT.

To evaluate the longterm efficacy and safety of arthroscopic synovectomy (AS) in children with oligoarticular juvenile idiopathic arthritis (JIA).Patients with oligoarticular JIA and persistent monoarticular involvement, refractory to nonsteroidal antiinflammatory drugs (NSAID) and/or intraarticular corticosteroid (IAC) treatment underwent AS followed, one month later, by IAC. The efficacy of AS was prospectively evaluated, and a good response was defined as absence of synovitis oror = 60% decrease in articular score from baseline. Clinical, laboratory, and radiological variables (radiographs, ultrasound, magnetic resonance imaging) were noted to examine possible factors predictive of the result.Twenty-two patients with JIA (15 female, 7 male) entered the study. Age at disease onset was 77 months (range 13-168). Mean disease duration at the time of AS was 50 months (3-324). Nineteen knees, 2 temporomandibular joints, and one shoulder were treated; the mean followup was 57 months (12-168). Thirty-six percent of patients relapsed within 12 months of the procedure, 14% within 24 months, and 14% thereafter. Eight patients (36%) remain in remission after a mean 65 months' followup. Variables found to be predictive of good response were persistent monoarticular course (p = 0.004), short disease duration at the time of AS (p = 0.03), and normal erythrocyte sedimentation rate and C-reactive protein at baseline (p = 0.008 and 0.01, respectively).AS is a safe but only partially effective procedure in patients with oligoarticular JIA. Best results are achieved early in the disease course in children with persistent monoarticular involvement and no evidence of systemic inflammation.

Background and aims: The aim of the present study is to evaluate whether advanced coronary atherosclerosis analysis by CCTA may improve prognostic stratification among diabetic patients at high cardiovascular risk (CV risk). Methods and results: The study population consisted of 265 consecutive diabetic patients at high CV risk who underwent CCTA for suspected CAD between January 2011 and December 2016. For every patients both traditional and advanced, qualitative and quantitative coronary plaque analysis were performed. The occurrence of cardiac death, ACS, and non-urgent revascularization were recorded at follow-up. Among the 265 patients enrolled, 21 were lost to follow-up, whereas 244 (92%) had a complete follow-up (mean 45 ± 22 months) and were classified at high (n = 67) or very high cardiovascular risk (n = 177), according to ESC Guidelines. A total of 63 events were recorded (3 Cardiac Death, 3 NSTEMI, 8 unstable angina, 36 late non-urgent revascularization and 13 non-cardiac death) in 57 different patients. Elevated fibro-fatty plaque volume was the only predictor of events over age, gender and traditional risk factor when ACS and MACE were considered as end-points [HR (95% CI) 6.01 (1.65–21.87), p = 0.006 and 3.46 (2.00–5.97); p < 0.001]. Conclusion: The present study confirms the prognostic role of advance coronary atherosclerosis evaluation beyond risk factors and stenosis severity, even in diabetics. Despite the very high cardiovascular risk of study population, a not negligible portion (23%) of patients exhibited totally normal coronaries.

Background: Graft occlusion after coronary artery bypass graft surgery (CABG) has been associated with native coronary artery competitive flow. Objectives: The present study aims to characterize the functional progression of coronary artery disease (CAD) in native vessels after CABG, and to assess the relationship between preoperative FFR as derived from angiography and graft occlusion. Methods: Multicenter study of consecutive patients undergoing CABG between 2013 and 2018, in whom a follow-up angiogram had been performed. Serial vessel-fractional flow reserve (vFFR) analyses were obtained in each major native coronary vessel before and after CABG, excluding post-anastomotic segments and graft conduits. Results: In 73 patients, serial angiograms were suitable for vFFR analysis, including 118 grafted (86 arterial and 32 saphenous grafts) and 64 non-grafted vessels. The median time between CABG and follow-up angiography was 2.4 years [IQR 1.5, 3.3]. Functional CAD progression, by means of decline in vFFR, was observed in grafted but not in non-grafted vessels (delta vFFR in grafted vessels 0.10 [IQR 0.05, 0.18] vs. 0.01 [IQR -0.01, 0.03], in non-grafted vessels, p < 0.001). Preoperative vFFR predicted graft occlusion (AUC: 0.66, 95% CI 0.52 to 0.80, p = 0.031). Conclusions: In patients undergoing CABG, preoperative vFFR derived from conventional angiograms without use of pressure wire was able to predict graft occlusion. Graft occlusion was more frequent in vessels with high vFFR values. Grafted native coronary vessels exhibited accelerated functional CAD progression, whereas in non-grafted native coronaries the functional status remained unchanged.

Background: In diabetic patients with multivessel coronary artery disease, coronary artery bypass grafting (CABG) has shown long-term benefits over percutaneous coronary intervention (PCI). Physiology-guided PCI has shown to improve clinical outcomes in multivessel coronary artery disease, though its impact in diabetic patients has never been investigated. We evaluated long-term clinical outcomes of diabetic patients with multivessel coronary artery disease treated with fractional flow reserve (FFR)–guided PCI compared with CABG. Methods: From 2010 to 2018, 4622 diabetic patients undergoing coronary angiography were screened for inclusion. The inclusion criterion was the presence of at least 2-vessel disease defined as with diameter stenosis ≥50%, in which at least 1 intermediate stenosis (diameter stenosis, 30%–70%) was treated or deferred according to FFR. Inverse probability of treatment weighting analysis was used to account for baseline differences with a contemporary cohort of patients treated with CABG. The primary end point was major adverse cardiovascular and cerebrovascular events, defined as all-cause death, myocardial infarction, revascularization, or stroke. Results: A total of 418 patients were included in the analysis. Among them, 209 patients underwent CABG and 209 FFR-guided PCI. At 5 years, the incidence of major adverse cardiovascular and cerebrovascular events was higher in the FFR-guided PCI versus the CABG group (44.5% versus 31.9%; hazard ratio, 1.60 [95% CI, 1.15–2.22]; P =0.005). No difference was found in the composite of all-cause death, myocardial infarction, or stroke (28.8% versus 27.5%; hazard ratio, 1.05 [95% CI, 0.72–1.53]; P =0.81). Repeat revascularization was more frequent with FFR-guided PCI (24.9% versus 8.2%; hazard ratio, 3.51 [95% CI, 1.93–6.40]; P Conclusions: In diabetic patients with multivessel coronary artery disease, CABG was associated with a lower rate of major adverse cardiovascular and cerebrovascular events compared with FFR-guided PCI, driven by a higher rate of repeat revascularization. At 5-year follow-up, no difference was observed in the composite of all-cause death, myocardial infarction, or stroke between CABG and FFR-guided PCI.

Dopo una premessa di sapore autobiografico sul mutamento di immagini della Prima e della Seconda Guerra mondiale nella coscienza di un baby-boomer italiano, l’autore ricostruisce il tormentato percorso di Piero Jahier e il progressivo emergere delle contraddizioni che caratterizzarono l’atteggiamento degli intellettuali verso la guerra. Dapprima un interventismo vivace e polemico, temperato da un vena solidaristica che distingue Jahier dai sodali di “Lacerba”; quindi, nelle pagine di Con me e con gli alpini, un’ambigua oscillazione fra atteggiamento paternalistico-pedagogico verso la truppa e identificazione empatica con il popolo contadino; infine, in testi sparsi, in versi e in prosa (poesie tarde, come Ultima marcia, o pagine di diario difficilmente databili) il graduale affiorare di sentimenti pacifisti.

The essay examines the political writings of Borgese in the years between 1914 and 1919 to illuminate the thematic intersections with the major novel Rubè and to measure the artistic and literary transformations and reworkings. The diplomatic activity of Borgese was very extensive and in-depth and the writings merged in magazines and then in volume constitute a non-marginal or secondary part of his journalistic-literary writing.
