Limited disease progression in endocrine surgery patients with treatment delays due to COVID-19.

Background: The COVID-19 pandemic profoundly impacted the delivery of care and timing of elective surgical procedures. Most endocrine-related operations were considered elective and safe to postpone, providing a unique opportunity to assess clinical outcomes under protracted treatment plans.

Methods: American Association of Endocrine Surgeon members were surveyed for participation.

A multifaceted study of hospital variables and interventions to improve inpatient satisfaction in a multi-hospital system.

Knowing the areas of service, actions, and parameters that can influence patient perception about a service provided can help hospital executives and healthcare workers to devise improvement plans, leading to higher patient satisfaction. To identify inpatient satisfaction determinants, assess their relationships with hospital variables, and improve patient satisfaction through interventions. We studied the inpatient population of an eight-hospital tertiary medical center in 2015.

A Behavior-Modification, Clinical-Grade Mobile Application to Improve Breast Cancer Survivors' Accountability and Health Outcomes.

Purpose: Only 34% of breast cancer survivors engage in the recommended level of physical activity because of a lack of accountability and motivation. Methodist Hospital Cancer Health Application (MOCHA) is a smartphone tool created specifically for self-reinforcement for patients with cancer through the daily accounting of activity and nutrition and direct interaction with clinical dietitians. We hypothesize that use of MOCHA will improve the accountability of breast cancer survivors and help them reach their personalized goals.

Nonlinear motion compensation using cubature Kalman filter for in vivo fluorescence microendoscopy in peripheral lung cancer intervention.

Fluorescence microendoscopy can potentially be a powerful modality in minimally invasive percutaneous intervention for cancer diagnosis because it has an exceptional ability to provide micron-scale resolution images in tissues inaccessible to traditional microscopy. After targeting the tumor with guidance by macroscopic images such as computed tomorgraphy or magnetic resonance imaging, fluorescence microendoscopy can help select the biopsy spots or perform an on-site molecular imaging diagnosis. However, one challenge of this technique for percutaneous lung intervention is that the respiratory and hemokinesis motion often renders instability of the sequential image visualization and results in inaccurate quantitative measurement.

A minimally invasive multimodality image-guided (MIMIG) system for peripheral lung cancer intervention and diagnosis.

Background: Lung cancer is the leading cause of cancer-related death in the United States, with more than half of the cancers are located peripherally. Computed tomography (CT) has been utilized in the last decade to detect early peripheral lung cancer. However, due to the high false diagnosis rate of CT, further biopsy is often necessary to confirm cancerous cases.

Image-guided fiberoptic molecular imaging in a VX2 rabbit lung tumor model.

Purpose: To show the feasibility of computed tomography (CT) image-guided fiberoptic confocal fluorescence molecular imaging in a rabbit lung tumor model.

Materials And Methods: Eight lung tumor models were created by injection of a VX2 cell suspension. The fluorescent imaging agent IntegriSense 680 was given to the animals 3.

Spatial resolution limits of multislice computed tomography (MS-CT), C-arm-CT, and flat panel-CT (FP-CT) compared to MicroCT for visualization of a small metallic stent.

Rationale And Objectives: Small metallic stents are increasingly used in the treatment of cerebral aneurysms and for revascularization in ischemic strokes. Realistic three-dimensional datasets of a stent were obtained by using three x-ray-based imaging methods in current clinical use. Multislice-CT (MS-CT), C-arm flat detector-CT (C-arm CT, ACT), and flat panel-CT (FP-CT) were compared with high-resolution laboratory MicroCT scans that served as a reference standard.

Anomalous hemodynamic effects of a self-expanding intracranial stent: comparing in-vitro and ex-vivo models using ultra-high resolution microCT based CFD.

Previous research on the effects of intracranial stents on arterial hemodynamics has involved computational hemodynamics (CHD) simulations applied to artificially generated stent models. In this study, accurate geometric reconstructions of in-vitro (PTFE tube) and ex-vivo (canine artery) deployed stents based on ultra-high resolution MicroCT imaging were used. The primary goal was to compare the hemodynamic effects of deployment in these two different models and to identify flow perturbations due to deployment anomalies such as stent malapposition and strut prolapse, important adverse mechanics occurring in clinical practice, but not considered in studies using idealized stent models.

Study of conformability of the new leo plus stent to a curved vascular model using flat-panel detector computed tomography (DynaCT).

Objective: In a previous study, we assessed the conformability limitations of self-expandable stents to a curved vascular model. The LEO stent (Balt Extrusion, Montmorency, France), one of the current self-expandable models available for intracranial aneurysm stenting, displayed 2 adverse mechanics: flattening of the stent midsection and inward crimping of the proximal and distal ends. We present a follow-up study in which we evaluate the conformability to curved vessels of a second-generation stent, LEO PLUS.
