A clinical prediction model for long-term functional outcome after traumatic spinal cord injury based on acute clinical and imaging factors.
(Journal of neurotrauma, 2012-09)To improve clinicians' ability to predict outcome after spinal cord injury (SCI) and to help classify patients within clinical trials, we have created a novel prediction model relating acute clinical and imaging information ... -
A latent factor linear mixed model for high-dimensional longitudinal data analysis.
(Statistics in medicine, 2013-10)High-dimensional longitudinal data involving latent variables such as depression and anxiety that cannot be quantified directly are often encountered in biomedical and social sciences. Multiple responses are used to characterize ... -
A tutorial on Bayesian multi-model linear regression with BAS and JASP.
(Behavior research methods, 2021-12)Linear regression analyses commonly involve two consecutive stages of statistical inquiry. In the first stage, a single 'best' model is defined by a specific selection of relevant predictors; in the second stage, the regression ... -
Artificial Intelligence Models Predict Operative Versus Nonoperative Management of Patients with Adult Spinal Deformity with 86% Accuracy.
(World neurosurgery, 2020-09)<h4>Objective</h4>Patients with ASD show complex and highly variable disease. The decision to manage patients operatively is largely subjective and varies based on surgeon training and experience. We sought to develop models ... -
Association of a peripheral blood metabolic profile with coronary artery disease and risk of subsequent cardiovascular events.
(Circ Cardiovasc Genet, 2010-04)BACKGROUND: Molecular tools may provide insight into cardiovascular risk. We assessed whether metabolites discriminate coronary artery disease (CAD) and predict risk of cardiovascular events. METHODS AND RESULTS: We performed ... -
Associations of genotypes and haplotypes of IL-17 with risk of gastric cancer in an eastern Chinese population.
(Oncotarget, 2016-12)Interleukin-17 plays a crucial role in inflammation-related carcinogenesis. We hypothesize that genetic variants in IL-17 are associated with gastric cancer (GCa) risk, and we genotyped five potentially functional single ... -
Can acute clinical outcomes predict health-related quality of life after stroke: a one-year prospective study of stroke survivors.
(Health and quality of life outcomes, 2018-11-21)<h4>Background</h4>Health-related quality of life (HRQoL) is a key metric to understand the impact of stroke from patients' perspective. Yet HRQoL is not readily measured in clinical practice. This study aims to investigate ... -
Chimpanzees and bonobos exhibit divergent spatial memory development.
(Dev Sci, 2012-11)Spatial cognition and memory are critical cognitive skills underlying foraging behaviors for all primates. While the emergence of these skills has been the focus of much research on human children, little is known about ... -
Credit scores, cardiovascular disease risk, and human capital.
(Proc Natl Acad Sci U S A, 2014-12-02)Credit scores are the most widely used instruments to assess whether or not a person is a financial risk. Credit scoring has been so successful that it has expanded beyond lending and into our everyday lives, even to inform ... -
Daily intake of antioxidants in relation to survival among adult patients diagnosed with malignant glioma.
(BMC Cancer, 2010-05-19)BACKGROUND: Malignant glioma is a rare cancer with poor survival. The influence of diet and antioxidant intake on glioma survival is not well understood. The current study examines the association between antioxidant intake ... -
Deficiency of α-1-antitrypsin influences systemic iron homeostasis.
(Int J Chron Obstruct Pulmon Dis, 2013)There is evidence that proteases and antiproteases participate in the iron homeostasis of cells and living systems. We tested the postulate that α-1 antitrypsin (A1AT) polymorphism and the consequent deficiency ... -
Dietary Patterns Associated with Cognitive Function among the Older People in Underdeveloped Regions: Finding from the NCDFaC Study.
(Nutrients, 2018-04-09)Although dietary patterns are crucial to cognitive function, associations of dietary patterns with cognitive function have not yet been fully understood. This cross-sectional study explored dietary patterns associated with ... -
Early Patient-Reported Outcomes Predict 3-Year Outcomes in Operatively Treated Patients with Adult Spinal Deformity.
(World neurosurgery, 2017-06)<h4>Background</h4>For patients with adult spinal deformity (ASD), surgical treatment may improve their health-related quality of life. This study investigates when the greatest improvement in outcomes occurs and whether ... -
Effects of the dietary approaches to stop hypertension diet, exercise, and caloric restriction on neurocognition in overweight adults with high blood pressure.
(Hypertension, 2010-06)High blood pressure increases the risks of stroke, dementia, and neurocognitive dysfunction. Although aerobic exercise and dietary modifications have been shown to reduce blood pressure, no randomized trials have examined ... -
Efficient coding of spatial information in the primate retina.
(The Journal of neuroscience : the official journal of the Society for Neuroscience, 2012-11)Sensory neurons have been hypothesized to efficiently encode signals from the natural environment subject to resource constraints. The predictions of this efficient coding hypothesis regarding the spatial filtering properties ... -
Energy recovery in individuals with knee osteoarthritis.
(Osteoarthritis Cartilage, 2014-06)OBJECTIVE: Pathological gaits have been shown to limit transfer between potential (PE) and kinetic (KE) energy during walking, which can increase locomotor costs. The purpose of this study was to examine whether energy exchange ... -
Evaluation of integrated respiratory gating systems on a Novalis Tx system.
(Journal of applied clinical medical physics, 2011-04-04)The purpose of this study was to investigate the accuracy of motion tracking and radiation delivery control of integrated gating systems on a Novalis Tx system. The study was performed on a Novalis Tx system, which is equipped ... -
Evidence from case-control and longitudinal studies supports associations of genetic variation in APOE, CETP, and IL6 with human longevity.
(Age (Dordr), 2013-04)In this study, we investigated 102 single-nucleotide polymorphisms (SNPs) covering the common genetic variation in 16 genes recurrently regarded as candidates for human longevity: APOE; ACE; CETP; HFE; IL6; IL6R; MTHFR; ... -
From spiking neuron models to linear-nonlinear models.
(PLoS Comput Biol, 2011-01-20)Neurons transform time-varying inputs into action potentials emitted stochastically at a time dependent rate. The mapping from current input to output firing rate is often represented with the help of phenomenological models ... -
