Respiratory modules are medical devices used to assist patients breathe. The aim of this article is develop a control method that achieves exact tracking time-varying target pressure, for unknown patient-hose-leak parameters and in the presence patient breathing effort. This achieved by an online estimation hose characteristics enables compensation pressure drop over hose. Stability closed-loop...

This research develops a novel data-integrated simulation to evaluate nurse-patient assignments (SIMNA) based on a real data set provided by a northeast Texas hospital. Tree-based models and kernel density estimation (KDE) were utilized to extract important knowledge from the data for the simulation. Classification and Regression Tree models, data mining tools for prediction and classification,...

A male patient in his 20s presented at our clinic with pain caused by bone metastases of the primitive neuroectodermal tumor, and Sr-89 was administrated to palliate the pain. After receiving the injection, the patient complained of a slight burning pain at the catheterized area. Slight reddening and small circular swelling (diameter, 0.5 cm) were observed at the catheterized area. Sr-89 extrav...

Accurate characterization of acute myocardial infarction (AMI) is crucial for the management of the patient. In this work we present a method for 3-dimensional (3D) velocity estimation and object tracking in sequences of ultrasound volume scans. Velocity estimation is based on motion estimation in 3D with maximum likelihood criteria. Tracking is carried out using a data association method based...

BACKGROUND Crowding occurs commonly in high volume emergency departments (ED) and has been associated with negative patient care outcomes. We aim to assess ED crowding in a median-low volume setting and evaluate associations with patient care outcomes. METHODS This was a prospective single-center study from November 14, 2016 until December 14, 2016. ED crowding was measured every 2 h by three...

PURPOSE In this work, a novel stochastic framework for patient positioning based on linac-mounted CB projections is introduced. Based on this formulation, the most probable shifts and rotations of the patient are estimated, incorporating interfractional deformations of patient anatomy and other uncertainties associated with patient setup. METHODS The target position is assumed to be defined b...

Ordinary least square (OLS) in regression has been widely used to analyze patient-level data in cost-effectiveness analysis (CEA). However, the estimates, inference and decision making in the economic evaluation based on OLS estimation may be biased by the presence of outliers. Instead, robust estimation can remain unaffected and provide result which is resistant to outliers. The objective of t...

objective(s): the objectives of this work was to assess the benefits of the application of physiologically based pharmacokinetic (pbpk) models in patients with different neuroendocrine tumours (net) who were treatedwith lu-177 dotatate. the model utilises clinical data on biodistribution of radiolabeled peptides (rlps) obtained by whole body scintigraphy (wbs) of the patients.methods: the blood...
