Barriers to and Facilitators of Implementing Team-Based Extracorporeal Membrane Oxygenation Simulation Study: Exploratory Analysis.

Intro: Extracorporeal membrane oxygenation (ECMO) is a critical tool in the care of severe cardiorespiratory dysfunction. Simulation training for ECMO has become standard practice. Therefore, Keck Medicine of the University of California (USC) holds simulation-training sessions to reinforce and improve providers knowledge.

Breastfeeding Among First-Time Mothers Reporting Housing Insecurity and Food Insecurity.

Despite health benefits to both infants and mothers, many are not breastfeeding as recommended by national guidelines. Prior studies examining the effects of housing insecurity and food insecurity on breastfeeding intention and duration have been limited and yielded mixed findings. To assess the relationship among housing insecurity, food insecurity, and breastfeeding, we conducted a secondary analysis of a cohort of nulliparous U.

A Case of Severe Erythroderma in a Patient with Pustular Psoriasis.

Case Presentation: A female patient with a known history of pustular psoriasis presented with sub-acute development of diffuse erythema and scaling of the skin with areas of exfoliation consistent with erythroderma. She was ill appearing and required admission and aggressive treatment with steroid-impregnated wet dressings, topical emollients, analgesics, and systemic immunosuppressants.

Discussion: Erythroderma is a dermatologic emergency characterized by diffuse erythema and scaling spanning greater than 90% of skin surfaces and is associated with a mortality rate as high as 64%.

Dosimetric optimization for dynamic mixed beam arc therapy (DYMBARC).

Background: Non-coplanarity and mixed beam modality could be combined to further enhance dosimetric treatment plan quality. We introduce dynamic mixed beam arc therapy (DYMBARC) as an innovative technique that combines non-coplanar photon and electron arcs, dynamic gantry and collimator rotations, and intensity modulation with photon multileaf collimator (MLC). However, finding favorable beam directions for DYMBARC is challenging due to the large solution space, machine component constraints, and optimization parameters, posing a highly non-convex optimization problem.

Monte Carlo dose calculation for photon and electron radiotherapy on dynamically deforming anatomy.

Background: Dose calculation in radiotherapy aims to accurately estimate and assess the dose distribution of a treatment plan. Monte Carlo (MC) dose calculation is considered the gold standard owing to its ability to accurately simulate particle transport in inhomogeneous media. However, uncertainties such as the patient's dynamically deforming anatomy can still lead to differences between the delivered and planned dose distribution.
