Toward Robotically Automated Femoral Vascular Access [PDF]
arXiv, 2021 Advanced resuscitative technologies, such as Extra Corporeal Membrane Oxygenation (ECMO) cannulation or Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), are technically difficult even for skilled medical personnel. This paper describes the core technologies that comprise a teleoperated system capable of granting femoral vascular ...

Determinants of cardiac output in health and heart failure
Experimental Physiology, EarlyView.Abstract Sustained physical exercise depends on delivery of oxygenated blood to exercising muscle. At least among healthy individuals, bulk transport of blood is tightly matched to metabolic demand, such that cardiac output increases by ∼6 L/min for every 1 L/min increase in oxygen uptake. Multiple factors contribute to the regulation of cardiac output,

Sensitivity analysis via the proportion of unmeasured confounding [PDF]
, 2019 In observational studies, identification of ATEs is generally achieved by assuming that the correct set of confounders has been measured and properly included in the relevant models. Because this assumption is both strong and untestable, a sensitivity analysis should be performed.

Variable Selection for Causal Inference via Outcome-Adaptive Random Forest [PDF]
arXiv, 2021 Estimating a causal effect from observational data can be biased if we do not control for self-selection. This selection is based on confounding variables that affect the treatment assignment and the outcome. Propensity score methods aim to correct for confounding. However, not all covariates are confounders.

Journal of Magnetic Resonance Imaging, Volume 61, Issue 5, Page 2130-2143, May 2025.Background Pulmonary hypertension (PH) is a life‐threatening. Differentiation pulmonary arterial hypertension (PAH) from pulmonary venous hypertension (PVH) is important due to distinct treatment protocols. Invasive right heart catheterization (RHC) remains the reference standard but noninvasive alternatives are needed.

Addressing Positivity Violations in Causal Effect Estimation using Gaussian Process Priors [PDF]
arXiv, 2021 In observational studies, causal inference relies on several key identifying assumptions. One identifiability condition is the positivity assumption, which requires the probability of treatment be bounded away from 0 and 1. That is, for every covariate combination, it should be possible to observe both treated and control subjects, i.e., the covariate ...
