Comparison of Three Groups of Patients Having Low Dose Rate Prostate Brachytherapy: Prostate-Specific Antigen Failure and Overall Survival.

Purpose To examine dosimetric and clinical outcomes for Cs-131 radioactive seed implant compared to Pd-103 and I-125.  Background/Significance Cs-131 is a novel isotope with relatively short half-life (9.7 days) that may have clinical advantages in seed implant treatments of prostate cancers.

Management of Prostate Cancer During COVID-19 Pandemic: Perspective From Urologists and Radiation Oncologists in COVID Dense Metro Detroit.

Objective To survey Urologists and Radiation Oncologists in Metropolitan Detroit regarding practice patterns in managing non-metastatic prostate cancer during the pandemic.  Methods An online survey was created to capture the perspective of the impact the COVID-19 restrictions have on the management of prostate cancer by Urologists and Radiation Oncologists in the Detroit Metropolitan area.  Results While most physicians felt that their facilities had adequate quantities of personal protective equipment (PPE), one in four offices reported that they did not have sufficient access to PPE.

Measurement scale influences in the evaluation of sight-word reading interventions.

Working with elementary students with disabilities, we used alternating treatment designs to evaluate and compare the effects of 2 computer-based flash card sight-word reading interventions, 1 with 1-s response intervals and another with 5-s response intervals. In Study 1, we held instructional time constant, applying both interventions for 3 min. Although students completed 6 learning trials per word during each 1-s session and 2 trials per word during each 5-s session, results showed similar acquisition rates for 1-s and 5-s words.

Learning rates and known-to-unknown flash-card ratios: comparing effectiveness while holding instructional time constant.

Using alternating treatments designs, we compared learning rates across 2 computer-based flash-card interventions (3 min each): a traditional drill intervention with 15 unknown words and an interspersal intervention with 12 known words and 3 unknown words. Each student acquired more words under the traditional drill intervention. Discussion focuses on the need to account for instructional time when learning procedures are evaluated and compared.

The effects of signaling stimulus presentation during noncontingent reinforcement.

The effects of signaling the return of items or attention during treatment with noncontingent reinforcement were examined. First, functional analyses showed that the problem behavior exhibited by 2 teenagers with developmental disabilities was sensitive to social positive reinforcement. Next, delivery of the stimulus that maintained problem behavior on a fixed-time (FT) schedule was compared to a condition in which the removal of the stimulus during the same FT schedule was immediately preceded by a statement indicating that the stimulus would be returned and the initiation of a digital timer.
