To determine the radial nerve palsy (RNP) rate and predictors of injury after humeral nonunion repair in a large multicenter sample.Consecutive retrospective cohort review.Eighteen academic orthopedic trauma centers.Three hundred seventy-nine adult patients who underwent shaft repair. Exclusion criteria were pathologic fracture complete motor RNP before surgery.Humeral assessment postoperative function.Measurements: Demographics, characteristics, preoperative function recovery.Twenty-six...
Background Elevated aminotransferase levels are commonly associated with compromised hepatic integrity from various insults. In sickle cell disease, aspartate transaminase (AST) is also released via intravascular hemolysis. This study was done to determine the pattern of changes in AST and alanine (ALT), particular AST:ALT ratio, relate these hemolytic state, which we consider be more important than cardiac dysfunction some individuals disease. Methods Serum were measured 330 subjects as...
Recently, there has been a concerted effort to implement advanced classical potential energy surfaces by adding higher order multipoles fixed point charge electrostatics in bid increase the accuracy of simulations condensed phase systems. One major hurdle is unwieldy nature expressions which part limited developers mostly including only dipoles and quadrupoles. In this paper, we present generalization Cartesian formulation electrostatic multipolar interactions that enables specification an...
To determine whether previously reported high mortality rates associated with bilateral femoral fractures have decreased over time.Retrospective review.Urban academic trauma center.54 adults treated at our center from 2000 to 2006. The 108 were initially external fixation (11%), reamed antegrade nailing (23%), and retrograde (67%).

In molecular simulations, it is sometimes necessary to compute the electrostatic potential at M target sites due a disjoint set of N charged source particles. Direct summation requires O(MN) operations, which prohibitively expensive when and are large. Here, we consider two alternative tree-based methods that reduce cost. The standard particle-cluster treecode partitions sources into an octree applies far-field approximation, whereas recently developed cluster-particle instead targets...
Particle mesh Ewald (PME) is generally the method of choice for handling electrostatics in simulations with periodic boundary conditions. The excellent efficiency PME on low processor counts largely due to use fast Fourier transform (FFT). However, FFT's high communication cost, scales poorly parallel. We develop a Coulomb tree (PCT) electrostatic interactions conditions as an alternative parallel simulations. verify accuracy PCT by comparison structural and dynamical properties three...
We present an approximate off-lattice kinetic Monte Carlo (KMC) method for simulating heteroepitaxial growth. The model aims to retain the speed and simplicity of lattice based KMC methods while capturing essential features that can arise in setting. Interactions between atoms are defined by interatomic potential which determines arrangement atoms. In this formulation we assign rates configuration changes keyed individual surface a fashion similar bond-counting schemes. is validated...
To evaluate the use of computed tomography (CT) imaging as a diagnostic tool for elbow arthrotomies using standardized cadaveric arthrotomy model.Nineteen intact fresh frozen cadaver elbows were CT scanned 2 mm cuts with sagittal and coronal reformats in plane joint used controls. An at posterocentral arthroscopic portal site was performed all specimens 4.5 millimeter trocar. After arthrotomy, underwent second scan followed by standard saline load test (SLT). Images randomized reviewed...
Summary Hemolytic anemia is common in sickle cell disease (SCD), but the course and extent differ, depending on genetic, epigenetic, environmental factors. In malaria‐endemic tropical environment, some vulnerable subjects would be infected impact of infection vary. Therefore, this study was to find malaria incidence associated changes laboratory indices 330 SCD subjects. Following blood smear preparation for falciparum detection, hematological biochemical were measured a comparison...
Electrostatic interactions involving point multipoles are being increasingly implemented to achieve higher accuracy in molecular simulations. A major drawback of multipolar electrostatics is the increased computational cost. Here we develop and compare two Cartesian tree algorithms which employ Taylor approximations hierarchical clustering speed up evaluation multipole interactions. We present results from applying compute free space Coulomb potential forces different sets interacting with...
In 2014, we implemented a geriatric hip fracture patient care pathway at our institution which was designed to improve outcomes and decrease time surgery.We analyzed retrospective data from 463 patients, aged greater than 50, who had surgical treatment for closed due low-energy injury between 2013 2016 an academic institution. Objective outcome measures included surgery, mortality rate, total hospital length of stay. Our primary goal the surgery definitive fixation within 24 hours admission...
Clostridium myonecrosis or gas gangrene is a life-threatening infection characterized by either traumatic atraumatic etiology. It has been widely described in patients with open wounds and immunocompromised patients, including malignancy. A third source can result from natural flora the gastrointestinal tract after bowel ischemia. This rare occurrence even less commonly pediatric population. We present patient who developed septicum as an iatrogenic complication clindamycin-induced difficile...
This paper develops a local triquintic interpolation method for function defined over unit cube mesh element. The resulting polynomial interpolant is isotropic and has global C2 continuity. coefficients are related to the its derivatives at eight corners of element by an invertible square matrix rank 216. proposed extension previously developed tricubic scheme with C1
