A pair of deep learning auto-contouring models for prostate cancer patients injected with a radio-transparent versus radiopaque hydrogel spacer.

Background: Absorbable hydrogel spacer injected between prostate and rectum is gaining popularity for rectal sparing. The spacer alters patient anatomy and thus requires new auto-contouring models.

Purpose: To report the development and comprehensive evaluation of two deep-learning models for patients injected with a radio-transparent (model I) versus radiopaque (model II) spacer.

Effect of Radiation Treatment at a High-Volume Center on Outcomes in Intermediate-Risk Prostate Cancer: An Analysis of the National Cancer Database.

Objective: To investigate the effect of radiation treatment at a high-volume center on overall survival in men with intermediate-risk prostate cancer.

Methods: From 2004 to 2015, 430,347 patients with intermediate-risk prostate cancer were identified in the National Cancer Database. Radiation case volume (RCV) of each hospital was calculated based on number of patients treated.

Outcomes for Young Men With Localized Intermediate-Risk Prostate Cancer: An Analysis of the NCDB.

Background: Primary management of localized, intermediate-risk prostate cancer consists of radical prostatectomy (RP), radiotherapy (RT) with short-course androgen deprivation therapy (ADT), or RT alone. The purpose of this study was to determine if these treatment strategies have equivalent overall survival (OS) in patients < 55 years old with intermediate-risk prostate cancer.

Patients And Methods: We identified 35,134 patients in the National Cancer Data Base with localized intermediate-risk prostate cancer treated with RP, RT + ADT, or RT from 2004 to 2013.

The Radiation Oncology Mentorship Initiative: Analysis of a Formal Mentoring Initiative for Medical Students Interested in Radiation Oncology.

The importance of mentorship in medicine and its impact on academic and professional development has been widely studied. However, mentorship for medical students in the field of radiation oncology is limited. Our radiation oncology department developed a formal medical student mentorship program in 2004.

Right heart catheterization using antecubital venous access: feasibility, safety and adoption rate in a tertiary center.

Objectives: To determine feasibility, safety, and adoption rates of right heart catheterization (RHC) using antecubital venous access (AVA) as compared to using the traditional approach of proximal venous access (PVA).

Background: RHC via PVA (i.e.

The body, its emotions, the self, and consciousness.

This article proposes a means for better understanding the self and consciousness. Data indicate that the basic "emotional brain" continually computes potential survival risk against reward to rank consequent "emotion scores" for all sensory inputs. These scores compete to yield winner-takes-all outcomes that determine the choice of attention or action.
