Effects of Pancreatic Fistula After Minimally Invasive and Open Pancreatoduodenectomy.

Importance: Postoperative pancreatic fistulas (POPF) are the biggest contributor to surgical morbidity and mortality after pancreatoduodenectomy. The impact of POPF could be influenced by the surgical approach.

Objective: To assess the clinical impact of POPF in patients undergoing minimally invasive pancreatoduodenectomy (MIPD) and open pancreatoduodenectomy (OPD).

Perioperative safety and oncological efficacy of simultaneous versus colorectal and liver first two-staged resections in patients with synchronous colorectal liver metastases: a systematic review and network meta-analysis.

Background: Previous meta-analyses have yielded conflicting results on the optimal surgical treatment strategy in patients with synchronous colorectal liver metastases (sCRLM). This network meta-analysis aims to provide an overview on colorectal-, liver first and simultaneous resections to treat sCRLM.

Methods: A search was conducted in MEDLINE, Embase and Cochrane CENTRAL (inception-July 11,2023).

A hybrid machine learning/deep learning COVID-19 severity predictive model from CT images and clinical data.

COVID-19 clinical presentation and prognosis are highly variable, ranging from asymptomatic and paucisymptomatic cases to acute respiratory distress syndrome and multi-organ involvement. We developed a hybrid machine learning/deep learning model to classify patients in two outcome categories, non-ICU and ICU (intensive care admission or death), using 558 patients admitted in a northern Italy hospital in February/May of 2020. A fully 3D patient-level CNN classifier on baseline CT images is used as feature extractor.

[Pulmonary embolism and SARS-CoV-2: analysis of patients hospitalized for pulmonary embolism and COVID-19 in a Northern Italian center].

Background: Coronavirus disease 2019 (COVID-19) has shown high morbidity and mortality and the relationship between pulmonary embolism (PE) and COVID-19 is well established in the literature.

Methods: We describe the characteristics of a cohort of COVID-19 patients (EP-COV) hospitalized at our Centre with PE, investigating how COVID-19 may have influenced their outcomes, as compared to patients without COVID-19 hospitalized for PE in the same months of 2020 (EP-2020) and 2019 (EP-2019).

Results: EP-COV patients (n=25) were younger (60.

Machine Learning to Predict In-Hospital Mortality in COVID-19 Patients Using Computed Tomography-Derived Pulmonary and Vascular Features.

Pulmonary parenchymal and vascular damage are frequently reported in COVID-19 patients and can be assessed with unenhanced chest computed tomography (CT), widely used as a triaging exam. Integrating clinical data, chest CT features, and CT-derived vascular metrics, we aimed to build a predictive model of in-hospital mortality using univariate analysis (Mann-Whitney test) and machine learning models (support vectors machines (SVM) and multilayer perceptrons (MLP)). Patients with RT-PCR-confirmed SARS-CoV-2 infection and unenhanced chest CT performed on emergency department admission were included after retrieving their outcome (discharge or death), with an 85/15% training/test dataset split.

Drug-Related Pneumonitis in Cancer Treatment during the COVID-19 Era.

Interstitial lung disease is recognized as a group of diseases with a different etiopathogenesis characterized by chronic lung inflammation with the accumulation of inflammatory cells, lymphocytes and macrophages, and the consequent release of proinflammatory cytokines. Various degrees of pulmonary fibrosis can be associated with this inflammatory condition. Interstitial lung disease related to oncological drugs is a relevant problem in clinical practice.

CT-derived Chest Muscle Metrics for Outcome Prediction in Patients with COVID-19.

Background Lower muscle mass is a known predictor of unfavorable outcomes, but its prognostic impact on patients with COVID-19 is unknown. Purpose To investigate the contribution of CT-derived muscle status in predicting clinical outcomes in patients with COVID-19. Materials and Methods Clinical or laboratory data and outcomes (intensive care unit [ICU] admission and death) were retrospectively retrieved for patients with reverse transcriptase polymerase chain reaction-confirmed SARS-CoV-2 infection, who underwent chest CT on admission in four hospitals in Northern Italy from February 21 to April 30, 2020.

COVID-19 acute respiratory distress syndrome: can iloprost have a role for the treatment?

Pulmonary infection of 2019-nCoV can frequently induce acute respiratory distress syndrome (ARDS) with partial pressure of arterial oxygen/fraction of inspired oxygen ratio (pO2/FiO2) of less than 300 mmHg. Moreover, it can be complicated with cardiac injury or arrhythmia, microvascular and large-vessel thrombosis. We describe a case of a patient with COVID19-ARDS and concomitant critical ischemia of the limbs.

Delirium in Patients with SARS-CoV-2 Infection: A Multicenter Study.

Objectives: The aims of this study are to report the prevalence of delirium on admission to the unit in patients hospitalized with SARS-CoV-2 infection, to identify the factors associated with delirium, and to evaluate the association between delirium and in-hospital mortality.

Design: Multicenter observational cohort study.

Settings: Acute medical units in four Italian hospitals.

Stroke in patients with COVID-19: Clinical and neuroimaging characteristics.

Acute cerebrovascular disease, particularly ischemic stroke, has emerged as a serious complication of infection by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiologic agent of the Coronavirus disease-2019 (COVID-19). Accumulating data on patients with COVID-19-associated stroke have shed light on specificities concerning clinical presentation, neuroimaging findings, and outcome. Such specificities include a propensity towards large vessel occlusion, multi-territory stroke, and involvement of otherwise uncommonly affected vessels.

Pneumomediastinum and subcutaneous emphysema in COVID-19: barotrauma or lung frailty?

Background: In mechanically ventilated acute respiratory distress syndrome (ARDS) patients infected with the novel coronavirus disease (COVID-19), we frequently recognised the development of pneumomediastinum and/or subcutaneous emphysema despite employing a protective mechanical ventilation strategy. The purpose of this study was to determine if the incidence of pneumomediastinum/subcutaneous emphysema in COVID-19 patients was higher than in ARDS patients without COVID-19 and if this difference could be attributed to barotrauma or to lung frailty.

Methods: We identified both a cohort of patients with ARDS and COVID-19 (CoV-ARDS), and a cohort of patients with ARDS from other causes (noCoV-ARDS).

Preliminary Analysis of Relationships between COVID19 and Climate, Morphology, and Urbanization in the Lombardy Region (Northern Italy).

The coronavirus disease 2019 (COVID-19) pandemic is the most severe global health and socioeconomic crisis of our time, and represents the greatest challenge faced by the world since the end of the Second World War. The academic literature indicates that climatic features, specifically temperature and absolute humidity, are very important factors affecting infectious pulmonary disease epidemics - such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS); however, the influence of climatic parameters on COVID-19 remains extremely controversial. The goal of this study is to individuate relationships between several climate parameters (temperature, relative humidity, accumulated precipitation, solar radiation, evaporation, and wind direction and intensity), local morphological parameters, and new daily positive swabs for COVID-19, which represents the only parameter that can be statistically used to quantify the pandemic.

Pulmonary thromboembolism in hospitalised COVID-19 patients at moderate to high risk by Wells score: a report from Lombardy, Italy.

Objectives: To present a single-centre experience on CT pulmonary angiography (CTPA) for the assessment of hospitalised COVID-19 patients with moderate-to-high risk of pulmonary thromboembolism (PTE).

Methods: We analysed consecutive COVID-19 patients (RT-PCR confirmed) undergoing CTPA in March 2020 for PTE clinical suspicion. Clinical data were retrieved.

CT-derived pulmonary vascular metrics and clinical outcome in COVID-19 patients.

To assess pulmonary vascular metrics on chest CT of COVID-19 patients, and their correlation with pneumonia extent (PnE) and outcome, we analyzed COVID-19 patients with an available previous chest CT, excluding those performed for cardiovascular disease. From February 21 to March 21, 2020, of 672 suspected COVID-19 patients from two centers who underwent CT, 45 RT-PCR-positives (28 males, median age 75, IQR 66-81 years) with previous CTs performed a median 36 months before (IQR 12-72 months) were included. We assessed PnE, pulmonary artery (PA) diameter, ascending aorta (Ao) diameter, and PA/Ao ratio.

Dural Metastases of Advanced Prostate Cancer Detected by F-Fluorocholine.

Prostate cancer with extensive dural metastases is very rare, with only few cases described in the literature. We report one such case of a 74-year-old man with advanced prostate cancer, and in relatively good clinical condition. The patient returned with complaints of headache and diplopia.

Stroke in patients with SARS-CoV-2 infection: case series.

Background: Italy is one of the most affected countries by the coronavirus disease 2019 (COVID-19). The responsible pathogen is named severe acute respiratory syndrome coronavirus (SARS-CoV-2). The clinical spectrum ranges from asymptomatic infection to severe pneumonia, leading to intensive care unit admission.

A Multifocal Glioneuronal Tumor with RGNT-Like Morphology Occupying the Supratentorial Ventricular System and Infiltrating the Brain Parenchyma.

Background: Rosette-forming glioneuronal tumors (RGNTs) with multifocal growth throughout the ventricular system are extremely rare, and only 1 case of RGNT with dissemination limited to supratentorial ventricles has previously been reported. Recent evidence based on molecular data suggest that low-grade glioneuronal tumors (GNT) involving the septum pellucidum and the lateral ventricles, with either dysembryoplastic neuroepithelial tumor-like or RGNT-like features, may belong to a neuropathologic entity distinct from cortical dysembryoplastic neuroepithelial tumor and "typical" fourth ventricle RGNT, respectively. Given their rarity, the classification of these neoplasms is still uncertain and their clinicopathological and radiological aspects are only partially known.

Medial temporal lobe atrophy and posterior atrophy scales normative values.

Objectives: The medial temporal lobe atrophy (MTA) and the posterior atrophy (PA) scales allow to assess the degree hippocampal and parietal atrophy from magnetic resonance imaging (MRI) scans. Despite reliable, easy and widespread employment, appropriate normative values are still missing. We aim to provide norms for the Italian population.

Diffuse white matter alteration in CLIPPERS: Advanced MRI findings from two cases.

Advanced MRI findings in two patients with probable chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) are presented. Diffusion tensor imaging indices (fractional anisotropy and mean diffusivity), evaluated in both patients at baseline MRI examination before treatment and during follow-up, indicated white matter structural changes not only affecting the brainstem, which represents the primary site of inflammatory damage, but also projection (corona radiata) and associative tracts in both patients, while alterations within the corpus callosum were detected in patient 1# at follow-up. Susceptibility weighted imaging (SWI) revealed hypointense lesions in both patients, MRI spectroscopy (MRS) indicated a mildly increased Cho/NAA ratio with no evidence of lipids/lactate peaks, indicating that it may be used as a non-invasive marker to identify CLIPPERS cases suspected for progression to lymphoma.

Neuroendocrine differentiation in castration resistant prostate cancer. Nuclear medicine radiopharmaceuticals and imaging techniques: A narrative review.

Background: Androgen Deprivation Therapy (ADT) is the primary treatment for patients suffering from relapsing or advanced prostate cancer (PC). Hormone therapy generally guarantees adequate clinical control of the disease for some years, even in those patients affected by widespread skeletal and soft tissue metastases. Despite ADT, however, most patients treated with hormones eventually progress to castration-resistant prostate cancer (CRPC), for which there are no effective treatments.

Early-Stage Supraglottic "In Situ" Squamous Cell Carcinoma of the Larynx Incidentally Detected by 18F-Fluorocholine PET/CT.

F-fluorocholine (F-FCH) PET/CT is widely used to study patients affected by prostate cancer. Despite its specificity, however, F-FCH may be taken up by other neoplasms such as multiple myeloma, lymphomas, lung, bladder, and colon cancer; brain tumors; and renal and hepatocellular carcinoma. This is due to its ability to evaluate the cell proliferation, which is typical of neoplastic cells.
