A Comprehensive Review Of Tic Disorders In Children, Keisuke Ueda, Kevin J. Black

Open Access Publications

Tics are characterized by sudden, rapid, recurrent, nonrhythmic movement or vocalization, and are the most common movement disorders in children. Their onset is usually in childhood and tics often will diminish within one year. However, some of the tics can persist and cause various problems such as social embarrassment, physical discomfort, or emotional impairments, which could interfere with daily activities and school performance. Furthermore, tic disorders are frequently associated with comorbid neuropsychiatric symptoms, which can become more problematic than tic symptoms. Unfortunately, misunderstanding and misconceptions of tic disorders still exist among the general population. Understanding tic disorders and their comorbidities …

Flexor Tendon Injury And Repair: The Influence Of Synovial Environment On The Early Healing Response In A Canine Mode, Hua Shen, Susumu Yoneda, Shelly E Sakiyama-Elbert, Qiang Zhang, Stavros Thomopoulos, Richard H Gelberman

Open Access Publications

BACKGROUND: Environmental conditions strongly influence the healing capacity of connective tissues. Well-vascularized extrasynovial tendons typically undergo a robust wound-healing process following transection and repair. In contrast, avascular intrasynovial tendons do not mount an effective repair response. The current study tests the hypothesis that flexor tendons, as a function of their synovial environment, exhibit unique inflammatory, angiogenic, and metabolic responses to injury and repair.

METHODS: Flexor tendons present a distinct opportunity to test the study hypothesis, as they have proximal regions that are extrasynovial and distal regions that are intrasynovial. In an internally controlled study design, the second and fifth forepaw …

Mri Radiomic Signature Of White Matter Hyperintensities Is Associated With Clinical Phenotypes, Martin Bretzner, Laura Heitsch, Chia-Ling Phuah, Et Al

Open Access Publications

Objective: Neuroimaging measurements of brain structural integrity are thought to be surrogates for brain health, but precise assessments require dedicated advanced image acquisitions. By means of quantitatively describing conventional images, radiomic analyses hold potential for evaluating brain health. We sought to: (1) evaluate radiomics to assess brain structural integrity by predicting white matter hyperintensities burdens (WMH) and (2) uncover associations between predictive radiomic features and clinical phenotypes.

Methods: We analyzed a multi-site cohort of 4,163 acute ischemic strokes (AIS) patients with T2-FLAIR MR images with total brain and WMH segmentations. Radiomic features were extracted from normal-appearing brain tissue (brain mask-WMH …

Disentangling The Complexity Of The Rumen Microbial Diversity Through Fractionation Using A Sucrose Density Gradient, Ruth Hernández, Hugo Jimenez, Cesar Vargas-Garcia, Alejandro Caro-Quintero, Alejandro Reyes

Open Access Publications

The ruminal microbial community is an important element in health, nutrition, livestock productivity, and climate impact. Despite the historic and current efforts to characterize this microbial diversity, many of its members remain unidentified, making it challenging to associate microbial groups with functions. Here we present a low-cost methodology for rumen sample treatment that separates the microbial community based on cell size, allowing for the identification of subtle compositional changes. In brief, the sample is centrifuged through a series of sucrose density gradients, and cells migrate to their corresponding density fraction. From each fraction, DNA is extracted and

Structure And Function Of Pancreatic Lipase-Related Protein 2 And Its Relationship With Pathological States, Guoying Zhu, Qing Fang, Fengshang Zhu, Dongping Huang, Changqing Yang

Open Access Publications

Pancreatic lipase is critical for the digestion and absorption of dietary fats. The most abundant lipolytic enzymes secreted by the pancreas are pancreatic triglyceride lipase (PTL or PNLIP) and its family members, pancreatic lipase-related protein 1 (PNLIPRP1or PLRP1) and pancreatic lipase-related protein 2 (PNLIPRP2 or PLRP2). Unlike the family's other members, PNLIPRP2 plays an elemental role in lipid digestion, especially for newborns. Therefore, if genetic factors cause gene mutation, or other factors lead to non-expression, it may have an effect on fat digestion and absorption, on the susceptibility to pancreas and intestinal pathogens. In this review, we will summarize what …

Open Access Publications

The production of pancreatic β cells is the most challenging step for curing diabetes using next-generation treatments. Adult pancreatic endocrine cells are thought to be maintained by the self-duplication of differentiated cells, and pancreatic endocrine neogenesis can only be observed when the tissue is severely damaged. Experimentally, this can be performed using a method named partial duct ligation (PDL). As the success rate of PDL surgery is low because of difficulties in identifying the pancreatic duct, we previously proposed a method for fluorescently labeling the duct in live animals. Using this method, we performed PDL on neurogenin3 (Ngn3)-GFP transgenic mice …

Emerging Genotype-Phenotype Relationships In Primary Ciliary Dyskinesia, Steven K Brennan, Thomas W Ferkol, Stephanie D Davis

Open Access Publications

Primary ciliary dyskinesia (PCD) is a rare inherited condition affecting motile cilia and leading to organ laterality defects, recurrent sino-pulmonary infections, bronchiectasis, and severe lung disease. Research over the past twenty years has revealed variability in clinical presentations, ranging from mild to more severe phenotypes. Genotype and phenotype relationships have emerged. The increasing availability of genetic panels for PCD continue to redefine these genotype-phenotype relationships and reveal milder forms of disease that had previously gone unrecognized.

Evaluation Of The Neonatal Sequential Organ Failure Assessment And Mortality Risk In Preterm Infants With Late-Onset Infection, Noa Fleiss, Angela N. Lewis, Krista E. Cooksey, Ameena N. Husain, Misty Good, Et Al

Open Access Publications

Importance: Infection in neonates remains a substantial problem. Advances for this population are hindered by the absence of a consensus definition for sepsis. In adults, the Sequential Organ Failure Assessment (SOFA) operationalizes mortality risk with infection and defines sepsis. The generalizability of the neonatal SOFA (nSOFA) for neonatal late-onset infection-related mortality remains unknown.

Objective: To determine the generalizability of the nSOFA for neonatal late-onset infection-related mortality across multiple sites.

Design, Setting, and Participants: A multicenter retrospective cohort study was conducted at 7 academic neonatal intensive care units between January 1, 2010, and December 31, 2019. Participants included 653 preterm ( …

Effects Of Dietary Restriction On Neuroinflammation In Neurodegenerative Diseases, Luigi Fontana, Laura Ghezzi, Anne H. Cross, Laura Piccio

Open Access Publications

Recent and accumulating work in experimental animal models and humans shows that diet has a much more pervasive and prominent role than previously thought in modulating neuroinflammatory and neurodegenerative mechanisms leading to some of the most common chronic central nervous system (CNS) diseases. Chronic or intermittent food restriction has profound effects in shaping brain and peripheral metabolism, immunity, and gut microbiome biology. Interactions among calorie intake, meal frequency, diet quality, and the gut microbiome modulate specific metabolic and molecular pathways that regulate cellular, tissue, and organ homeostasis as well as inflammation during normal brain aging and CNS neurodegenerative diseases, including …

Microbiota Signals Suppress B Lymphopoiesis With Aging In Mice, Joseph R Krambs, Darlene A Monlish, Feng Gao, Laura G Schuettpelz, Daniel C Link

Open Access Publications

Aging is associated with significant changes in hematopoiesis that include a shift from lymphopoiesis to myelopoiesis and an expansion of phenotypic hematopoietic stem cells (HSCs) with impaired self-renewal capacity and myeloid-skewed lineage differentiation. Signals from commensal flora support basal myelopoiesis in young mice; however, their contribution to hematopoietic aging is largely unknown. Here, we characterize hematopoiesis in young and middle-aged mice housed under specific pathogen free (SPF) and germ-free (GF) conditions. The marked shift from lymphopoiesis to myelopoiesis that develops during aging of SPF mice is mostly abrogated in GF mice. Compared with aged SPF mice, there is a marked …

Antibiotic-Driven Intestinal Dysbiosis In Pediatric Short Bowel Syndrome Is Associated With Persistently Altered Microbiome Functions And Gut-Derived Bloodstream Infections, Robert Thänert, Anna Thänert, Jocelyn Ou, Adam Bajinting, Carey-Ann D Burnham, Holly J Engelstad, Maria E Tecos, I Malick Ndao, Carla Hall-Moore, Colleen Rouggly-Nickless, Mike A Carl, Deborah C Rubin, Nicholas O Davidson, Phillip I Tarr, Barbara B Warner, Gautam Dantas, Brad W Warner

Open Access Publications

Surgical removal of the intestine, lifesaving in catastrophic gastrointestinal disorders of infancy, can result in a form of intestinal failure known as short bowel syndrome (SBS). Bloodstream infections (BSIs) are a major challenge in pediatric SBS management. BSIs require frequent antibiotic therapy, with ill-defined consequences for the gut microbiome and childhood health. Here, we combine serial stool collection, shotgun metagenomic sequencing, multivariate statistics and genome-resolved strain-tracking in a cohort of 19 patients with surgically-induced SBS to show that antibiotic-driven intestinal dysbiosis in SBS enriches for persistent intestinal colonization with BSI causative pathogens in SBS. Comparing the gut microbiome composition of …

Climate Change And Antibiotic Resistance: A Deadly Combination, Jason P Burnham

2020-Current year OA Pubs

Climate change is driven primarily by humanity's use of fossil fuels and the resultant greenhouse gases from their combustion. The effects of climate change on human health are myriad and becomingly increasingly severe as the pace of climate change accelerates. One relatively underreported intersection between health and climate change is that of infections, particularly antibiotic-resistant infections. In this perspective review, the aspects of climate change that have already, will, and could possibly impact the proliferation and dissemination of antibiotic resistance are discussed.
