Assignment-Control Plots: A Visual Companion for Causal Inference Study Design [PDF]

arXiv, 2021
An important step for any causal inference study design is understanding the distribution of the treated and control subjects in terms of measured baseline covariates. However, not all baseline variation is equally important. In the observational context, balancing on baseline variation summarized in a propensity score can help reduce bias due to self ...

Incidence of epidural haematoma and neurological injury in cardiovascular patients with epidural analgesia/anaesthesia: systematic review and meta-analysis [PDF]

, 2006
BACKGROUND: Epidural anaesthesia is used extensively for cardiothoracic and vascular surgery in some centres, but not in others, with argument over the safety of the technique in patients who are usually extensively anticoagulated before, during, and ...

Evaluating Cardiovascular Surgical Planning in Mobile Augmented Reality [PDF]

arXiv, 2022
Advanced surgical procedures for congenital heart diseases (CHDs) require precise planning before the surgeries. The conventional approach utilizes 3D-printing and cutting physical heart models, which is a time and resource intensive process. While rapid advances in augmented reality (AR) technologies have the potential to streamline surgical planning,

Pattern and Outcome of Chest Injuries at Bugando Medical Centre in Northwestern Tanzania. [PDF]

, 2011
Chest injuries constitute a continuing challenge to the trauma or general surgeon practicing in developing countries. This study was conducted to outline the etiological spectrum, injury patterns and short term outcome of these injuries in our setting ...

Heegaard Floer homology and chirally cosmetic surgeries [PDF]

, 2021
A pair of surgeries on a knot is chirally cosmetic if they result in homeomorphic manifolds with opposite orientations. We find new obstructions to the existence of such surgeries coming from Heegaard Floer homology; in particular, we make use of immersed curve formulations of knot Floer homology and the corresponding surgery formula. As an application,

Institutional analysis of intra‐ and post‐operative tracheostomy management for risk reduction

World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 8, Issue 4, Page 370-377, December 2022., 2022
Abstract Objectives Determine variability in intra‐ and post‐operative management of tracheostomies (trachs) at our institution as existing literature suggests that trachs are a frequent trigger for airway‐related emergencies. Catalyze the development of an institution‐wide protocols for trach care.

Deep Learning Models for Calculation of Cardiothoracic Ratio from Chest Radiographs for Assisted Diagnosis of Cardiomegaly [PDF]

arXiv, 2021
We propose an automated method based on deep learning to compute the cardiothoracic ratio and detect the presence of cardiomegaly from chest radiographs. We develop two separate models to demarcate the heart and chest regions in an X-ray image using bounding boxes and use their outputs to calculate the cardiothoracic ratio. We obtain a sensitivity of 0.

Exceptional Cosmetic surgeries on $S^3$ [PDF]

Topology and its Applications, Volume 204, 15 May 2016, Pages 217-229, 2015
This paper concerns the truly or purely cosmetic surgery conjecture. We give a survey on exceptional surgeries and cosmetic surgeries. We prove that the slope of an exceptional truly cosmetic surgery on a hyperbolic knot in $S^3$ must be $\pm 1$ and the surgery must be toroidal but not Seifert fibred.

All exceptional surgeries on alternating knots are integral surgeries [PDF]

Algebr. Geom. Topol. 8 (2008) 2161-2173, 2008
We show that all exceptional surgeries on hyperbolic alternating knots in the 3-sphere are integral surgeries.
