Optimization of target grouping in distributive stereotactic radiosurgery using the excel evolutionary solver.

Purpose: Distributive stereotactic radiosurgery (dSRS) is a form of fractionation where groups of metastases are treated with a full single-fraction dose on different days. The challenge with dSRS is determining optimal target groupings to maximize the distance between targets treated in the same fraction. This study aimed to develop and validate an accessible optimization technique for distributing brain metastases into optimal treatment fractions using a genetic algorithm.

A predictive model for Gamma Knife intermediate dose spill: R50%.

Purpose: Minimizing intermediate dose spill in stereotactic radiosurgery (SRS) for brain treatment is crucial. Intermediate dose spill correlates with the exposure of normal brain tissue to high doses, which increases the risk of radionecrosis. R50%, defined as the volume of the 50% of prescription isodose cloud/planning target volume, is one metric for intermediate dose spill.

Gender Differences in "Making Weight" Behaviors Among U.S. Iraq and Afghan War Veterans: Implications for Future Health.

Failure to "make weight" carries significant consequences for military personnel including additional training burdens, stigma, possible demotion, or even separation from service. The aim of this study was to examine potential gender differences in, and investigate relationships between, military making weight behavior and obesity, eating pathology, and mental health later in life. Iraq and Afghanistan war era Veterans ( = 1,126, 51.
