Early Occurrence of Adverse Events in Hospitalized Patients With COVID-19 and Beneficial Effect of Anticoagulation.

Background/aim: This study analyzed the characteristics of patients with COVID-19 with major events during the first days of hospitalization.

Patients And Methods: This is a retrospective analysis of prospectively collected data from consecutive patients admitted to two hospitals in Athens, Greece. The characteristics of patients with COVID-19 who suffered the primary endpoint (venous thromboembolic events, intubation, and death) during the first days of hospitalization were analyzed.

Beneficial Effects of Intermediate Dosage of Anticoagulation Treatment on the Prognosis of Hospitalized COVID-19 Patients: The ETHRA Study.

Background/aim: To investigate the efficacy (prognosis, coagulation/inflammation biomarkers) and safety (bleeding events) of different anticoagulation dosages in COVID-19 inpatients.

Patients And Methods: COVID-19 inpatients (Athens, Greece) were included. The "Enhanced dose THRomboprophylaxis in Admissions (ETHRA)" protocol was applied in certain Departments, suggesting the use of intermediate anticoagulation dosage.

An analysis of some dosimetric uncertainties in radiation therapy.

A phenomenological analysis of the effect of several parameters on the precision of delivered dose is presented; experimental data are used to demonstrate the effect of these parameters on the delivered dose. It is shown that some setups possess inherently better precision than others; the need for strict quality control during patient treatment is supported by the data.

A new technique for hepatic infusional chemotherapy.

Constant-infusion intra-arterial chemotherapy is associated with a significantly greater tumor response rate and perhaps an improved survival rate. Many intra-arterial drug delivery systems have been described, the most popular of which is the implanted Infusaid pump. Unfortunately, this is an expensive device that requires considerable experience in its implantation and maintenance.
