Modern methods for longitudinal data analysis, capabilities, caveats and cautions.
TL;DR: Comparison of the two major approaches for longitudinal data analysis in terms of model assumptions, model parameter interpretation, applicability and limitations, using both real and simulated data is focused on.
Laparoscopic appendectomy is safe and efficacious for the elderly: An analysis using the National Surgical Quality Improvement Project database
Michael J. Kim,Fergal J. Fleming,Douglas D. Gunzler,Susan Messing,Rabih M. Salloum,John R. T. Monson +5 more
TL;DR: During the 30-day postoperative period, no correlation with major complications was found, and the findings showed a beneficial association with regard to minor complications, and laparoscopic appendectomy is a safe procedure for elderly patients.
Heterogeneous depression trajectories in multiple sclerosis patients.
Douglas D. Gunzler,Nathan Morris,Adam T. Perzynski,Daniel Ontaneda,Farren B.S. Briggs,Deborah M. Miller,Robert A. Bermel +6 more
TL;DR: The LCGA approach described in this paper and applied to MS patients provides a template for improved use of an EHR data base for understanding heterogeneous depression screening trajectories and may be used to more closely monitor patients that are expected to maintain high or unstable depression levels.
Characterizing fatigue phenotypes with other symptoms and clinically relevant outcomes among people with multiple sclerosis
TL;DR: The results indicate that the magnitude of fatigue experienced may be more important to consider than the type of fatigue when characterizing fatigue phenotypes, and future research should explore whether tailoring interventions to environmental barriers, self-efficacy, and fatigue catastrophizing reduce the likelihood of transitioning to a more severe phenotype.
Adding Contralaterally Controlled Electrical Stimulation of the Triceps to Contralaterally Controlled Functional Electrical Stimulation of the Finger Extensors Reduces Upper Limb Impairment and Improves Reachable Workspace but not Dexterity: A Randomized Controlled Trial.
Jayme S. Knutson,Nathaniel S. Makowski,Mary Y. Harley,Terri Z. Hisel,Douglas D. Gunzler,Richard D. Wilson,John Chae +6 more
TL;DR: Adding contralaterally controlled elbow extension to hand contralATERally controlled functional electrical stimulation does not improve on gains in hand dexterity, but it further reduces upper limb impairment and improves reachable workspace measured in the laboratory.
