Efficacy And Feasibility Of Short-Stretch Compression Therapy For Filarial Lymphedema In Sri Lanka, Jaimee M Hall, Nirmitha Lalindi De Silva, Janaka Ruben, Sandani S Thilakarathne, Thishan Channa Yahathugoda, Philip J Budge

2020-Current year OA Pubs

The WHO-recommended essential package of care (EPC) for filarial limb lymphedema consists of daily limb washing, entry lesion management, limb protection, exercises, and elevation. Decongestive therapy (DT) with compression bandaging by trained lymphedema therapists adds additional benefit but is unavailable for most in low- and middle-income countries (LMICs). To determine whether DT using self-adjustable, short-stretch compression garments (SSCG), prefitted using portable, three-dimensional infrared imaging (3DII), would be effective and feasible in LMIC settings, we conducted a pilot 6-week, interventional, single-group, open-label pilot study in Galle, Sri Lanka. Ten participants with Dreyer stage 3 lymphedema used SSCG for 2 weeks after …

Differential Cognitive And Behavioral Development From 6 To 24 Months In Autism And Fragile X Syndrome, Lindsay J Mullin, Lisa Flake, Kelly N Botteron, Et Al.

2020-Current year OA Pubs

BACKGROUND: Specifying early developmental differences among neurodevelopmental disorders with distinct etiologies is critical to improving early identification and tailored intervention during the first years of life. Recent studies have uncovered important differences between infants with fragile X syndrome (FXS) and infants with familial history of autism spectrum disorder who go on to develop autism themselves (FH-ASD), including differences in brain development and behavior. Thus far, there have been no studies longitudinally investigating differential developmental skill profiles in FXS and FH-ASD infants.

METHODS: The current study contrasted longitudinal trajectories of verbal (expressive and receptive language) and nonverbal (gross and fine motor, …

The Latissimus Dorsi Creates A Dynamic Track For The Inferior Angle Of The Scapula During Arm Abduction In Humans, Alp Paksoy, Doruk Akgün, Henry Gebauer, Daniel Karczewski, Lucca Lacheta, John M Tokish, Aaron Chamberlain, Philipp Moroder

2020-Current year OA Pubs

BACKGROUND: The importance of several scapulothoracic muscles, including trapezius and serratus anterior, in maintaining physiological scapula kinematics has been highlighted in the past. However, the relationship between the scapula and the latissimus dorsi muscle remains unclear. Our clinical surgical observation is that the latissimus dorsi does not directly attach but rather runs superficial to the inferior angle of the scapula. Based on this observation, we hypothesise that the latissimus dorsi creates a dynamic track on which the scapula glides under the muscle belly during elevation of the arm, creating the latissimus-scapula overlap (LSO).

METHODS: All consecutive patients who had a …

Epitope Mapping Of Japanese Encephalitis Virus Neutralizing Antibodies By Native Mass Spectrometry And Hydrogen/Deuterium Exchange, Jagat Adhikari, James Heffernan, Melissa Edeling, Estefania Fernandez, Prashant N Jethva, Michael S Diamond, Daved H Fremont, Michael L Gross

2020-Current year OA Pubs

Japanese encephalitis virus (JEV) remains a global public health concern due to its epidemiological distribution and the existence of multiple strains. Neutralizing antibodies against this infection have shown efficacy in in vivo studies. Thus, elucidation of the epitopes of neutralizing antibodies can aid in the design and development of effective vaccines against different strains of JEV. Here, we describe a combination of native mass spectrometry (native-MS) and hydrogen/deuterium exchange mass spectrometry (HDX-MS) to complete screening of eight mouse monoclonal antibodies (MAbs) against JEV E-DIII to identify epitope regions. Native-MS was used as a first pass to identify the antibodies that …

Simulation-Based Analysis Of Trial Design In Regional Anesthesia, Melisa Pasli, Dmitry Tumin, Ryan Guffey

2020-Current year OA Pubs

BACKGROUND: In regional anesthesia, the efficacy of novel blocks is typically evaluated using randomized controlled trials (RCTs), the findings of which are aggregated in systematic reviews and meta-analyses. Systematic review authors frequently point out the small sample size of RCTs as limiting conclusions from this literature. We sought to determine via statistical simulation if small sample size could be an expected property of RCTs focusing on novel blocks with typical effect sizes.

METHODS: We simulated the conduct of a series of RCTs comparing a novel block versus placebo on a single continuous outcome measure. Simulation analysis inputs were obtained from …

Border-Associated Macrophages In The Central Nervous System, Rui Sun, Haowu Jiang

2020-Current year OA Pubs

Tissue-resident macrophages play an important role in the local maintenance of homeostasis and immune surveillance. In the central nervous system (CNS), brain macrophages are anatomically divided into parenchymal microglia and non-parenchymal border-associated macrophages (BAMs). Among these immune cell populations, microglia have been well-studied for their roles during development as well as in health and disease. BAMs, mostly located in the choroid plexus, meningeal and perivascular spaces, are now gaining increased attention due to advancements in multi-omics technologies and genetic methodologies. Research on BAMs over the past decade has focused on their ontogeny, immunophenotypes, involvement in various CNS diseases, and potential …

A Phase I Trial Of Pevonedistat In Combination With Ruxolitinib For The Treatment Of Myelofibrosis, Tim Kong, Nicole Gaudin, Karyn Gordon, Maggie J Cox, Amy W Zhou, Stephen T Oh

2020-Current year OA Pubs

Janus kinase 2 (JAK2) inhibitors such as ruxolitinib have become standard-of-care therapy for patients with myeloproliferative neoplasms (MPNs); however, activation of alternate oncogenic pathways including nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB) has limited durable response as single-agent therapy. With the rationale of targeting both pathways, we conducted a phase I dose escalation trial of pevonedistat in combination with ruxolitinib for the treatment of patients with myelofibrosis (NCT03386214). The primary objective was to assess the safety and tolerability of combination therapy with additional objectives of treatment efficacy and alterations of biomarkers. There were no dose-limiting toxicities observed with most …

2020-Current year OA Pubs

BACKGROUND: Breastfeeding has long-lasting effects on children's cognition, behavioral, mental and physical health. Previous research shows parental characteristics (e.g., education, race/ethnicity, income level) are associated with breastfeeding initiation and duration. Further, research shows significant variation in access to community resources by race/ethnicity. It is unclear how community resources may impact breastfeeding practices and how this might intersect with maternal race/ethnicity.

METHODS: This study combined nationally-representative data from the Study of Attitudes and Factors Effecting Infant Care (SAFE), which surveyed US mothers immediately after the infant's birth and at two to six months of infant age, with the Child Opportunity Index …

Microglia At Sites Of Atrophy Restrict The Progression Of Retinal Degeneration Via Galectin-3 And Trem2, Chen Yu, Yun Chen, Jinchao Hou, Marco Colonna, Et Al.

2020-Current year OA Pubs

Outer retinal degenerations, including age-related macular degeneration (AMD), are characterized by photoreceptor and retinal pigment epithelium (RPE) atrophy. In these blinding diseases, macrophages accumulate at atrophic sites, but their ontogeny and niche specialization remain poorly understood, especially in humans. We uncovered a unique profile of microglia, marked by galectin-3 upregulation, at atrophic sites in mouse models of retinal degeneration and human AMD. In disease models, conditional deletion of galectin-3 in microglia led to phagocytosis defects and consequent augmented photoreceptor death, RPE damage, and vision loss, indicating protective roles. Mechanistically, Trem2 signaling orchestrated microglial migration to atrophic sites and induced galectin-3 …

Inositol Phosphatase Inpp4b Sustains Ilc1s And Intratumoral Nk Cells Through An Akt-Driven Pathway, Vincent Peng, Tihana Trsan, Raki Sudan, Bishan Bhattarai, Victor S Cortez, Martina Molgora, Jean Vacher, Marco Colonna

2020-Current year OA Pubs

Innate lymphoid cells (ILCs) are a heterogeneous population of lymphocytes that coordinate early immune responses and maintain tissue homeostasis. Type 1 innate immune responses are mediated by natural killer (NK) cells and group 1 ILCs (ILC1s). Despite their shared features, NK cells and ILC1s display profound differences among various tissue microenvironments. Here, we identify the inositol polyphosphatase INPP4B as a hallmark feature of tissue-resident ILC1s and intratumoral NK cells using an scRNA-seq atlas of tissue-associated and circulating NK/ILC1s. Conditional deletion of Inpp4b in ILC1s and NK cells reveals that it is necessary for the homeostasis of tissue-resident ILC1s but not …

Multi-View Representation Learning For Tabular Data Integration Using Inter-Feature Relationships, Sandhya Tripathi, Bradley A Fritz, Mohamed Abdelhack, Michael S Avidan, Yixin Chen, Christopher R King

2020-Current year OA Pubs

OBJECTIVE: An applied problem facing all areas of data science is harmonizing data sources. Joining data from multiple origins with unmapped and only partially overlapping features is a prerequisite to developing and testing robust, generalizable algorithms, especially in healthcare. This integrating is usually resolved using meta-data such as feature names, which may be unavailable or ambiguous. Our goal is to design methods that create a mapping between structured tabular datasets derived from electronic health records independent of meta-data.

METHODS: We evaluate methods in the challenging case of numeric features without reliable and distinctive univariate summaries, such as nearly Gaussian and …

Extracellular Domain Mutations Of The Egf Receptor Differentially Modulate High-Affinity And Low-Affinity Responses To Egf Receptor Ligands, Jennifer L Macdonald-Obermann, Linda J Pike

2020-Current year OA Pubs

The EGF receptor is mutated in a number of cancers. In most cases, the mutations occur in the intracellular tyrosine kinase domain. However, in glioblastomas, many of the mutations are in the extracellular ligand binding domain. To determine what changes in receptor function are induced by such extracellular domain mutations, we analyzed the binding and biological response to the seven different EGF receptor ligands in three common glioblastoma mutants-R84K, A265V, and G574V. Our data indicate that all three mutations significantly increase the binding affinity of all seven ligands. In addition, the mutations increase the potency of all ligands for stimulating …
