Pelvic floor muscle training with biofeedback or feedback from a physiotherapist for urinary and anal incontinence after childbirth - a systematic review.

Background: Childbirth is one of the biggest risk factors for incontinence. Urinary and anal incontinence can cause pain and social limitations that affect social life, cohabitation, and work. There is currently no up-to-date literature study on the effect of pelvic floor muscle training with feedback from a physiotherapist, which involves verbal instructions based on vaginal and anal digital palpation, compared to treatment without feedback (e.

Optimization of tumor-treating field therapy for triple-negative breast cancer cells in vitro via frequency modulation.

Purpose: Currently, tumor-treating field (TTField) therapy utilizes a single "optimal" frequency of electric fields to achieve maximal cell death in a targeted population of cells. However, because of differences in cell size, shape, and ploidy during mitosis, optimal electric field characteristics for universal maximal cell death may not exist. This study investigated the anti-mitotic effects of modulating electric field frequency as opposed to utilizing uniform electric fields.

Efficacy and selectivity of tumor-treating field therapy for triple-negative breast cancer cells via in-house delivery device.

Purpose: Triple-negative breast cancer continues to be one of the leading causes of death in women, making up 7% of all cancer deaths. Tumor-treating electric fields are low-energy, low-frequency oscillating electric fields that induce an anti-proliferative effect on mitotic cells in glioblastoma multiforme, non-small cell lung cancer, and ovarian cancer. Little is known about effects of tumor-treating fields on triple-negative breast cancer and known research for tumor-treating fields only utilizes low (< 3 V/cm) electric field intensities.

SU-E-J-06: A Time Dependence Analysis of CBCT Image Quality and Mechanical Stability.

Purpose: To quantify the change, if any, in flexmap correction factors and image quality with the XVI system over a course of several years and from these results, assess their clinical impact.

Methods: Flexmap, a calibration procedure which corrects for imperfect gantry rotation for cone-beam CT reconstruction, and image quality tests were performed on three Elekta Synergy linacs equipped with XVI. Data was collected per month over three years.

SU-E-T-382: An Analysis of VMAT Monthly Quality Assurance.

Purpose: The purpose of this study is to quantify the change in monthly VMAT quality assurance (QA) and determine the tests to maintain consistent delivery with a baseline.

Methods: VMAT monthly QA has been performed for over 14 months on two Elekta Synergy LINACs. A baseline was established at acceptance and the monthly QA results were compared to those initial values.
