Though dosimetry has a multitude of treatment modalities, software, and workflows to aid in the treatment planning process, treatment planners are still responsible for several tedious and monotonous tasks that could decrease their planning efficiency. The purpose of this study was to determine if scripting could improve treatment planning efficiency for multiple brain lesion stereotactic radiosurgery (SRS) volumetric arc therapy cases by reducing planning time commitment. A script was developed for multiple brain lesion SRS cases using Eclipse scripting application programming interface with the intention of improving treatment planning efficiency by creating optimization structures and importing prescription and suggested OS dose metrics to the optimizer.

Background: High levels of burden and, in more severe instances, burnout represents a significant issue for caregivers of patients with advanced cancer. Early identification and management of caregiver distress and cultivating caregiver resiliency are seldom considered elements of routine care.

Aim: To leverage the complementary expertise of palliative medicine and social work using an integrated model of care to assess and manage caregiver needs.

Introduction: Balloon-occluded retrograde transvenous obliteration (BRTO) is recommended for secondary prevention of gastric variceal bleeding in the American Association for the Study of Liver Disease (AASLD) guidelines, as an alternative to Transjugular intrahepatic portosystemic shunt (TIPS). However, there is significant heterogeneity in how BRTO is performed, including how and how long to occlude the outflow venous shunt amongst other variables such as variceal size, flow rate, agent used, and preparation technique. We propose a method using foam sclerotherapy and reducing balloon occlusion to as little as 30 min, with assessment of the efficacy of this shorter balloon inflation time.

Introduction: The San Antonio Uniformed Services Health Education Consortium (SAUSHEC) is the largest group of residency programs in the Department of Defense. In an effort to provide improved Quality Improvement and Patient Safety (QI/PS) training for its residents, SAUSHEC created the position of Chief of QI/PS for Residents in the academic year 2014-2015. The Chief of QI/PS for Residents was based in the Internal Medicine residency program but also assisted with SAUSHEC-wide QI/PS projects.

Protein kinase D (PKD) is a novel family of serine/threonine kinases targeted by the second messenger diacylglycerol. It has been implicated in many important cellular processes and pathological conditions. However, further analysis of PKD in these processes is severely hampered by the lack of a PKD-specific inhibitor that can be readily applied to cells and in animal models.

This protocol describes assay development, validation and implementation of automated immobilized metal affinity for phosphochemicals (IMAP)-based fluorescence polarization (FP) and time-resolved fluorescence resonance energy transfer (TR-FRET) high-throughput screening (HTS) assays for identification of low-molecular-weight kinase inhibitors. Both procedures are performed in miniaturized kinase reaction volumes and involve the stepwise addition of test or control compounds, enzyme and substrate/ATP. Kinase reactions are stopped by subsequent addition of IMAP-binding buffer.

Nucleic acid-binding innate immune receptors such as Toll-like receptor 7 (TLR7) and TLR9 have been implicated in the development of some autoimmune pathologies. The Y chromosome-linked genomic modifier Yaa, which correlates with a duplication of Tlr7 and 16 other genes, exacerbates lupus-like syndromes in several mouse strains. Here we demonstrated that duplication of the Tlr7 gene was the sole requirement for this accelerated autoimmunity, because reduction of Tlr7 gene dosage abolished the Yaa phenotype.
