The American Association of Physicists in Medicine Task Group 119 instructed institutions to use a low-dose threshold of 10% or a region of interest determined by the jaw setting when they collected gamma analysis quality assurance (QA) data for the planar dose distribution. However, there are no clinical data to quantitatively demonstrate the impact of the low-dose threshold on the gamma index...

Given the increased number of patients hospitalized for acute medical illnesses and the associated risk of venous thromboembolism (VTE), the use of prophylaxis has become a public health matter. Thromboprophylaxis is not widely practiced in acutely ill medical patients, due in part to the heterogeneity of this group and the perceived difficulty in assessing those who would most benefit from tre...

The main pharmacological aspects of pharmacodynamics (PD) and pharmacokinetics (PK) of aspirin as antiplatelet agent were unravelled between the late sixties and the eighties, and low-dose aspirin given once daily has been shown to be a mainstay in the current treatment and prevention of cardiovascular disorders. Nevertheless, several PD and PK aspects of aspirin in selected clinical conditions...

In this issue of Blood, Larocca et al in a large prospective study show that thromboprophylaxis with low-dose aspirin is very effective in previously untreated myeloma patients with a low thromboembolic risk receiving lenalidomide with low-dose dexamethasone.

Background For radiological protection and control, the International Commission on Radiological Protection (ICRP) provides nominal risk coefficients related to radiation exposure, which can be extrapolated using excess relative absolute obtained from Life Span Study of atomic bomb survivors in Hiroshima Nagasaki with dose dose-rate effectiveness factor (DDREF). Materials Methods Since it is im...

Whole-gland low-dose rate (LDR) brachytherapy has been a well-established modality of treating low-risk prostate cancer. Treatment in a focal manner has the advantages of reduced toxicity to surrounding organs. Focal treatment using LDR brachytherapy has been relatively unexplored, but it may offer advantages over other modalities that have established experiences with a focal approach. This is...
