Engaging Medical Students as Teachers in the Medical Education Podcast.

is a medical education podcast that utilizes an innovative approach to undergraduate medical education by engaging medical students as teachers. This report describes the podcast, the benefits of engaging students as teachers, and future directions to improve the platform and formally study its impact.

Role of simulation-based training and assessment to improve brachytherapy competency among radiation oncology residents.

Simulation is a technique used in healthcare to replicate clinical scenarios and improve patient safety, efficacy, and efficiency. Simulation-based medical education facilitates training and assessment in healthcare without increasing risk to patients, supported by ample evidence from surgical/procedural specialties. Simulation in radiation oncology has been leveraged to an extent, with successful examples of both screen-based and hands-on simulators that have improved confidence and performance in trainees.

Treatment of Internal Mammary Nodes is Associated With Improved Overall Survival in Breast Cancer: A Meta-Analysis.

Introduction: The role of internal mammary nodal irradiation (IMNI) as a component of regional nodal radiotherapy is a controversial issue in breast radiation oncology with conflicting results presented in recent landmark trials. We thus created a meta-analysis of available data to better ascertain the potential benefit of IMNI. We hypothesize that with the increased power available within a meta-analysis, IMNI will prove to improve overall survival (OS) in breast cancer.

Inhibition of tyrosine kinase Fgr prevents radiation-induced pulmonary fibrosis (RIPF).

Cellular senescence is involved in the development of pulmonary fibrosis as well as in lung tissue repair and regeneration. Therefore, a strategy of removal of senescent cells by senolytic drugs may not produce the desired therapeutic result. Previously we reported that tyrosine kinase Fgr is upregulated in ionizing irradiation-induced senescent cells.

Outcomes of 3D MRI based HDR brachytherapy with hybrid multichannel vaginal cylinder applicator and freehand needles for treatment of vaginal disease.

Freehand needles can be used with multichannel vaginal cylinders (MCVC) to cover vaginal cancer >7 mm thick or with supra-vaginal extension. We report our institutional outcomes using this novel hybrid technique. Patients with vaginal malignancies treated with HDR BT using MCVC plus freehand needles from 2014-2021 at our institution were identified.

Effect of short-term corticosteroid usage on acute urinary toxicity following Cs-131 prostate brachytherapy.

Purpose: To evaluate short-term patient reported urinary quality of life scores in patients with prostate cancer treated at our institution with and without perioperative prednisone following Cesium-131 (Cs) prostate LDR brachytherapy.

Methods And Materials: We started routinely using a perioperative 7-day course of prednisone at a dose of 5 mg per day, beginning 1 day prior to Cs prostate LDR brachytherapy from 2013 with goal of improving acute urinary symptomatology. One hundred consecutive patients treated with prednisone were selected, with comparison to 100 consecutive patients who were not treated with prednisone.

A primer on time-driven activity-based costing in brachytherapy.

Emphasis on value-based healthcare has led to increasing use of time-driven activity-based costing (TDABC) across medical departments. When applied to brachytherapy, TDABC provides insight into differences in costs across various modes of therapy, the nuances that drive cost including institutional factors and involved personnel, and discrepancies in reimbursement which influence clinical practice. This is especially important with the new alternative payment model (APM) in radiation oncology which offers fixed reimbursement per 90-day episode of care.

Emerging role of immunotherapy in locally advanced non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) accounts for 85% of the cases of lung cancer in the United States, and 70% of patients with NSCLC have locally advanced or metastatic disease at the time of diagnosis. The 5-year overall survival rate for patients with locally advanced NSCLC is 15% to 20%. The traditional treatment paradigm for unresectable locally advanced NSCLC consists of platinum-based chemotherapy with concurrent radiation.

National patterns of care for early-stage penile cancers in the United States: How is radiation and brachytherapy utilized?

Purpose: Per American Brachytherapy Society guidelines, cT1-2N0 penile cancers <4 cm in diameter are excellent candidates for curative brachytherapy. Using that criterion, we evaluated national patterns of care and predictors of use of radiation techniques using the National Cancer Database.

Methods And Materials: The National Cancer Database was queried for men with cT1-2N0 penile cancers <4 cm in size.

MEF-2 isoforms' (A-D) roles in development and tumorigenesis.

Myocyte enhancer factor (MEF)-2 plays a critical role in proliferation, differentiation, and development of various cell types in a tissue specific manner. Four isoforms of MEF-2 (A-D) differentially participate in controlling the cell fate during the developmental phases of cardiac, muscle, vascular, immune and skeletal systems. Through their associations with various cellular factors MEF-2 isoforms can trigger alterations in complex protein networks and modulate various stages of cellular differentiation, proliferation, survival and apoptosis.

In vivo and in vitro immunogenicity of novel MHC class I presented epitopes to confer protective immunity against chronic HTLV-1 infection.

Human T-cell leukemia virus type 1 (HTLV-1) has infected as many as 10 million people worldwide. While 90% are asymptomatic, 5% develop severe diseases including adult T-cell leukemia/lymphoka (ATLL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). No vaccine against HTLV-1 exists, and screening programs are not universal.
