Background: The effect of a pulmonary embolism response team (PERT) in the short-term prognosis of patients with acute symptomatic pulmonary embolism (PE) lacks clarity. We therefore aimed at evaluating the effect of a PERT team on short-term mortality among patients with acute PE.

Methods: We retrospectively reviewed consecutive patients with acute symptomatic PE enrolled in a single-center registry between 2007 and 2022.

Article Synopsis
  • Liver SBRT is being evaluated for its effectiveness in accurately positioning patients for treatment, focusing on comparing fiducial markers against liver contours and bone references.
  • A study involving 18 patients analyzed the differences in displacement when using these methods, revealing that fiducials were more reliable in positioning.
  • Results indicated that liver contouring yielded smaller displacements compared to bone references and was nearly as precise as fiducials, suggesting it could be a viable alternative when fiducials aren't used.

To date, the ventricular myocardial band is the anatomical-functional model that best explains cardiac mechanics during systolic-diastolic phenomena in the cardiac cycle. The implications of the model fundamentally affect the anatomical interpretation of the ventricular myocardium, giving meaning to the direction that muscle fibers take, turning them into an object of study with potential clinical, imaging, and surgical applications. Re-interpreting the anatomy of the ventricular muscle justifies changes in the physiological interpretation, from its functional focus as a fiber unraveling the mechanical phenomena carried out during systole and diastole.

Objectives: Transjugular intrahepatic portosystemic shunt (TIPS) is increasingly used in the management of refractory ascites. Controversy exists regarding the predictive factors of unfavorable outcomes, useful for patient selection. The primary aim was to identify predictive factors of 1-year survival or recurrent severe hepatic encephalopathy in patients with cirrhosis undergoing covered TIPS for refractory ascites.

Background: Ivermectin is a drug that has been shown to be active against coronavirus disease 19 (COVID-19) in previous studies. Healthcare personnel are highly exposed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Therefore, we decided to offer them ivermectin as a pre-exposure prophylaxis (PrEP) method.

Background & Aims: Fontan surgery is used to treat a variety of congenital heart malformations, and may lead to advanced chronic liver disease in the long-term. This study examines the prevalence, characteristics and predictors of liver nodules in patients following Fontan surgery.

Methods: This was a prospective, cross-sectional, observational study conducted at 8 European centres.

Purpose: Acute mesenteric ischaemia (AMI) accounts for about 1:1000 acute hospital admissions. Untreated, AMI will cause mesenteric infarction, intestinal necrosis, an overwhelming inflammatory response and death. Early intervention can halt and reverse this process leading to a full recovery, but the diagnosis of AMI is difficult and failure to recognize AMI before intestinal necrosis has developed is responsible for the high mortality of the disease.

Purpose: This study compared the histologic parameters and outcomes of two types of grafts in large vertical maxillary defects: a composite graft of recombinant human bone morphogenetic protein-2/acellular collagen sponge (rhBMP-2/ACS), crushed cancellous freeze-dried allogeneic bone (CCFDAB), and platelet-rich plasma (PRP); and size-matched 100% autogenous grafts.

Materials And Methods: Twenty patients each were treated with a composite graft, which contained 1.05 mg rhBMP-2/ACS per two-tooth segment together with CCFDAB and PRP, or a 100% autogenous graft prior to implant placement.

Membranoproliferative glomerulonephritis was observed in a seven-month-old male cocker spaniel dog. The clinical, microbiological, biochemical, radiographic and ultrasonographic examinations ruled out neoplasia, congenital disease and infectious disease. The anamnesis revealed that the owner had vaccinated the dog seven times, one vaccination per month, without veterinarian supervision.
