Vein wall thickness and severity of pulmonary involvement due to sars n-cov2 virus infection.

Background: An observational study involving patients recovered from COVID-19 was conducted in order to evaluate the presence/absence of vein wall thickness increasing, according to the severity of pulmonary involvement quantified with a CT-scoring system.

Methods: The venous wall thickness (VWT) of 31 patients (23 males and 8 females) with COVID 19 previously admitted to Federico II University Hospital of Naples was evaluated through ultrasound measurement of the common femoral Vein 1 cm proximal to the saphenous-femoral junction and the popliteal Vein 1 cm distal to the confluence of gemellary veins. Measurements were taken with an automated tool to avoid human error.

Minimally invasive ileocecal valve resection in ileocecal Crohn's disease.

Aim: Considering ileocolic resection as a surgical standard for the treatment of ileocecal valve Crohn's disease, we propose a limited resection of the terminal ileum and ileocecal valve with ileocecal anastomosis.

Material Of Study: Three patiens between 20 and 37 years of age, diagnosed with Crohn's disease unresponsive to medical therapy, who have stenoses or fissures confined to the terminal ileum and ileocecal valve, seen during instrumental investigations.

Results: The proposed procedure allowed us to perform a minimal resection and reconstruction of a new ileocecal valve.

An integrated approach for coastal cliff susceptibility: The case study of Procida Island (southern Italy).

Procida Island, located in the Gulf of Naples (southern Italy), is characterized by steep cliffed coasts, articulated in a succession of headlands and small embayments with narrow pocket beaches, such as Ciraccio and Chiaia, often characterized by instability. In this study, a methodology for coastal cliff susceptibility assessment has been conceived based on hydraulic and geomorphological characteristics, which supported the construction of a Cliff Stability Index (CSI). The geomorphological characteristics are related to the whole cliff face, the cliff material resistance, and the cliff failure mechanisms.

Hand-Sewn Versus Stapled Small Bowel Anastomoses in Patients With Secondary Mesenteric Ischemia.

Introduction: Although stapled anastomoses have been widely evaluated in the context of the elective surgery, few reports compared manual with stapled anastomoses in patients undergoing emergency surgery. The aim of this study is to compare the outcome of hand-sewn end-to-end anastomoses with stapled side-to-side and stapled end-to-side anastomoses in patients undergoing small bowel resection for acute mesenteric ischemia secondary to intestinal obstruction.

Methods: From January 2015 to June 2021 all the hemodynamically stable patients undergoing emergency surgery with small bowel resection for intestinal obstruction were enrolled in this study.

Image Sensors for Wave Monitoring in Shore Protection: Characterization through a Machine Learning Algorithm.

Waves propagating on the water surface can be considered as propagating in a dispersive medium, where gravity and surface tension at the air-water interface act as restoring forces. The velocity at which energy is transported in water waves is defined by the group velocity. The paper reports the use of video-camera observations to study the impact of water waves on an urban shore.
