The developed quantitative mechanical model shows that the stepwise vortex profile is stabilized by the balance of hydrodynamic and surface tension forces. Vortex is observed not only in films from catanionic surfactant solutions, but also in films from silica and latex particle suspensions, which contain smaller surfactant micelles.Individual weight loss outcomes with intensive behavioral therapy (IBT) for obesity are variable. The present study assessed whether visit attendance, dietary self-monitoring, medication, and meal-replacement adherence were associated with 52-week weight loss with IBT and tested whether these relationships were independent of associations with early weight loss.  https://www.selleckchem.com/products/Rapamycin.html  This was a secondary analysis of a randomized trial in which 150 participants (76.1% female, 55.8% white, BMI = 38.8 ± 4.8 kg/m2) received either IBT alone, IBT with liraglutide 3.0 mg/d, or IBT-liraglutide combined with a 12-week meal replacement diet (Multi-component). In the full sample, visit attendance accounted for 14.8% of the variance in 52-week weight loss and dietary self-monitoring added 14.9%. Only self-monitoring was independently associated with weight loss. In the 100 liraglutide-treated participants, medication adherence accounted for an additional 9.9% of the variance in 52-week weight loss, and both self-monitoring and medication adherence were independent correlates. For the 50 Multi-component participants, meal replacement adherence did not predict weight loss. Early weight loss was associated with higher early and subsequent session attendance and dietary self-monitoring. However, self-monitoring and medication adherence remained important correlates of total weight loss when controlling for this variable. Strategies that help improve self-monitoring consistency and medication usage could improve weight loss with IBT.The terms "safety and quality" (SAQ) have become inextricably linked, highly utilized terms that together encompass a wide range of parameters within medical departments. Safety has always been a priority in radiation oncology; quality assurance has been foundational to our practice. Despite this increased focus and attention on SAQ, the "what" of SAQ remains ill-defined, largely because of the vast number of indicators that fall under this umbrella. Similarly, the "how" of developing and maintaining the highest standards of SAQ is not formulaic and varies based on the unique setting of individual practices. There are several excellent resources available to inform SAQ in radiation oncology, including the American Society for Radiation Oncology's (ASTRO) "Safety is No Accident", which provides an overview of safety and quality standards and resources. This review is intended as a brief summary of key considerations, with the goal of providing a practical framework and context for improving or developing a SAQ program in radiation oncology practices. We believe that the following ten key elements, drawn from numerous reports that have appeared over the last decade examining this topic, should be considered when conceptualizing a practice-based approach to SAQ Establishing a strong safety culture, establishing a structured program for safety and quality, establishing up-to-date, relevant, and accessible policies and procedures, a system for peer review, systems to assess and reduce risk, an educational program focused on safety and quality, development and review of meaningful quality metrics, utilization of a physics quality control (QC) system, well-defined models for staffing, training and professional development, and finally, validation from external bodies via accreditations and audits. These ten items are addressed herein.Purpose Automated tools can help identify radiation treatment plans of unacceptable quality. To this end, we developed a quality verification technique to automatically verify the clinical acceptability of beam apertures for four-field box treatments of patients with cervical cancer. By comparing the beam apertures to be used for treatment with a secondary set of beam apertures developed automatically, this quality verification technique can flag beam apertures that may need to be edited to be acceptable for treatment. Methods and materials The automated methodology for creating verification beam apertures uses a deep learning model trained on beam apertures and digitally-reconstructed radiographs from 255 clinically acceptable planned treatments (as rated by physicians). These verification apertures were then compared with the treatment apertures using spatial comparison metrics to detect unacceptable treatment apertures. We tested the quality verification technique on beam apertures from 80 treatment plans. assurance program.Background & aims Gastric per oral endoscopic pyloromyotomy (GPOEM) is a promising treatment for gastroparesis. There are few data on the long-term outcomes of this procedure. We investigated long-term outcomes of GPOEM treatment of patients with refractory gastroparesis. Methods We conducted a retrospective case-series study of all patients who underwent GPOEM for refractory gastroparesis at a single center (n=97), from June 2015 through March 2019; 90 patients had more than 3 months follow-up data and were included in our final analysis. We collected data on gastroparesis cardinal symptom index (GCSI) scores (measurements of postprandial fullness or early satiety, nausea and vomiting, and bloating) and SF-36 questionnaire scores (measures quality of life). The primary outcome was clinical response to GPOEM, defined as a decrease of at least 1 point in the average total GCSI score with more than a 25% decrease in at least 2 subscales of cardinal symptoms. Recurrence was defined as a return to baseline GCSI otic regression, patients with high BMIs had increased odds of GPOEM failure (OR, 1.097; 95% CI, 1.022-1.176; P=.010) and patients receiving psychiatric medications had a higher risk of GPOEM failure (OR, 1.33; 95% CI, 0.110-1.008; P=.052). Conclusions In retrospective analysis of 90 patients who underwent GPOEM for refractory gastroparesis, 81.1% had a clinical response at initial follow-up of their procedure. 1 year after GPOEM, 69.1% of all patients had a clinical response and 85.2% of initial responders maintained a clinical response. Patients maintained a clinical response and improved quality of life for as long as 3 years after the procedure. High BMI and long duration gastroparesis were associated with failure of GPOEM.
