Case Report: Capitalizing on Development and Activity-Dependent Plasticity, an Interaction With Pediatric-Onset Spinal Cord Injury.

Front Pediatr

March 2022

Department of Neurological Surgery, Kosair Charities Endowed Chair in Pediatric NeuroRecovery, University of Louisville, Louisville, KY, United States.

Background: Spinal cord injury (SCI) in infancy halts typical development secondary to paralysis/paresis and the limited ability to engage with the environment. Traditional therapies further restrict a child via bracing, equipment, and medications. In contrast, activity-based restorative therapies (ABRT) promote activation of the neuromuscular system below the level of injury and affords a more typical sensorimotor experience.

Nonalcoholic fatty liver disease (NAFLD) is a major global public health concern affecting more than 25% of the world's population. Although obesity and diabetes are major risk factors for NAFLD, they cannot account for all cases, indicating the importance of other factors such as environmental exposures. Cadmium (Cd) exposure is implicated in the development of NAFLD; however, the influence of early life, in utero Cd exposure on the development of diet-induced NAFLD is poorly understood.

The pathogenesis of schizophrenia is rarely attributed to dysfunction of the cerebellum. However, coordination of mental processes might involve the cerebellum and a cortico-cerebellar-thalamic-cortical circuit (CCTCC) that can mediate that process has been proposed. We present the case of a 31-year-old male patient with a family history of psychosis who developed schizophrenia in association with a slow-growing glioblastoma at the left posterior cerebellar pontine angle.

The cGAS-STING pathway: more than fighting against viruses and cancer.

Cell Biosci

December 2021

Department of Pediatrics, The Pediatric Research Institute, The University of Louisville School of Medicine, Louisville, KY, 40292, USA.

In the classic Cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) synthase (cGAS)-stimulator of interferon genes (STING) pathway, downstream signals can control the production of type I interferon and nuclear factor kappa-light-chain-enhancer of activated B cells to promote the activation of pro-inflammatory molecules, which are mainly induced during antiviral responses. However, with progress in this area of research, studies focused on autoimmune diseases and chronic inflammatory conditions that may be relevant to cGAS-STING pathways have been conducted. This review mainly highlights the functions of the cGAS-STING pathway in chronic inflammatory diseases.

Preoperative Albumin, Transferrin, and Total Lymphocyte Count as Risk Markers for Postoperative Complications After Total Joint Arthroplasty: A Systematic Review.

J Am Acad Orthop Surg Glob Res Rev

September 2020

From the Howard University College of Medicine (Dr. Mbagwu), Washington, DC; the Mount Sinai Hospital (Dr. Mbagwu), New York City, NY; the Department of Orthopaedic Surgery (Dr. Sloan, Dr. Charette, Dr. Kamath, Dr. Nelson), University of Pennsylvania; the Department of Surgery (Dr. Sloan, Dr. Charette, Dr. Nelson), University of Pennsylvania, Philadelphia, PA; the Department of Orthopaedic Surgery (Dr. Neuwirth), Columbia University Medical Center, New York City, NY; the Division of Orthopaedic Surgery (Dr. Baldwin), Department of Surgery, Children's Hospital of Philadelphia, Philadelphia, PA; the Orthopaedic and Rheumatologic Institute (Dr. Kamath), Cleveland Clinic, Cleveland, OH; the Nth Dimensions, Chicago, IL, (Dr. Mason); the University of Louisville School of Medicine (Dr. Mason), Louisville, KY; and the University of Texas Medical Branch (Dr. Mason), Galveston, TX.

Introduction: The purpose of this systematic review is to identify whether poor nutrition, as defined by the more commonly used markers of low albumin, low transferrin, or low total lymphocyte count (TLC), leads to more postoperative complications. We hypothesized that it may be possible to identify the levels of these laboratory values at which point total joint arthroplasty (TJA) may be ill advised. To this end, we analyzed the available literature regarding links between these three variables on postoperative complications after TJA.

Diabetic cardiomyopathy-pathophysiological heart remodelling and dysfunction that occurs in absence of coronary artery disease, hypertension and/or valvular heart disease-is a common diabetic complication. Elabela, a new peptide that acts via Apelin receptor, has similar functions as Apelin, providing beneficial effects on body fluid homeostasis, cardiovascular health and renal insufficiency, as well as potentially beneficial effects on metabolism and diabetes. In this study, Elabela treatment was found to have profound protective effects against diabetes-induced cardiac oxidative stress, inflammation, fibrosis and apoptosis; these protective effects may depend heavily upon SIRT3-mediated Foxo3a deacetylation.

Mobile devices with health apps, direct-to-consumer genetic testing, crowd-sourced information, and other data sources have enabled research by new classes of researchers. Independent researchers, citizen scientists, patient-directed researchers, self-experimenters, and others are not covered by federal research regulations because they are not recipients of federal financial assistance or conducting research in anticipation of a submission to the FDA for approval of a new drug or medical device. This article addresses the difficult policy challenge of promoting the welfare and interests of research participants, as well as the public, in the absence of regulatory requirements and without discouraging independent, innovative scientific inquiry.
