Low-dose radiotherapy to the lungs using an interventional radiology C-arm fluoroscope: Monte Carlo treatment planning and dose measurements in a postmortem subject.

The goal of this study was to use Monte Carlo (MC) simulations and measurements to investigate the dosimetric suitability of an interventional radiology (IR) c-arm fluoroscope to deliver low-dose radiotherapy to the lungs.A previously-validated MC model of an IR fluoroscope was used to calculate the dose distributions in a COVID-19-infected patient, 20 non-infected patients of varying sizes, and a postmortem subject. Dose distributions for PA, AP/PA, 3-field and 4-field treatments irradiating 95% of the lungs to a 0.

Monte Carlo simulations and phantom validation of low-dose radiotherapy to the lungs using an interventional radiology C-arm fluoroscope.

Purpose: To use MC simulations and phantom measurements to investigate the dosimetry of a kilovoltage x-ray beam from an IR fluoroscope to deliver low-dose (0.3-1.0 Gy) radiotherapy to the lungs.

The effect of continuous combined HRT on glucose homeostasis and plasma lipids. A placebo-controlled study in postmenopausal women with type 2 diabetes.

Background: Hyperandrogenicity in women is a risk factor for cardiovascular disease and noninsulin-dependent diabetes mellitus (NIDDM). Estradiol alone decreases hyperandrogenicity and have beneficial effects on glucose metabolism and plasma lipids in postmenopausal women with type 2 diabetes.

Objectives: To analyse effects on glucose homeostasis and plasma lipids by 2 mg estradiol and 1mg norethisterone acetate (NETA) given as a daily tablet during 6 months in postmenopausal women with type 2 diabetes.
