Identifying And Validating Subtypes Within Major Psychiatric Disorders Based On Frontal-Posterior Functional Imbalance Via Deep Learning, Miao Chang, Fay Y Womer, Xiaohong Gong, Weixiong Zhang, Et Al

Open Access Publications

Converging evidence increasingly implicates shared etiologic and pathophysiological characteristics among major psychiatric disorders (MPDs), such as schizophrenia (SZ), bipolar disorder (BD), and major depressive disorder (MDD). Examining the neurobiology of the psychotic-affective spectrum may greatly advance biological determination of psychiatric diagnosis, which is critical for the development of more effective treatments. In this study, ensemble clustering was developed to identify subtypes within a trans-diagnostic sample of MPDs. Whole brain amplitude of low-frequency fluctuations (ALFF) was used to extract the low-dimensional features for clustering in a total of 944 participants: 581 psychiatric patients (193 with SZ, 171 with BD, and 217 …

Does The Presence Of Chondral Lesions Negatively Affect Patient-Determined Outcomes After Arthroscopic Rotator Cuff Repair?, Keith M Baumgarten, Peter S Chang, Will E Schweinle

Open Access Publications

Background: There are limited data available to guide patients to their prognosis when glenohumeral chondral lesions are found during arthroscopic rotator cuff repair.

Hypothesis: The primary hypothesis was that patients with glenohumeral chondral lesions will have inferior outcomes after arthroscopic rotator cuff repair compared with patients without chondral lesions. The secondary hypothesis was that patients with concomitant chondral lesions will have more severe preoperative symptoms compared with those without chondral lesions.

Study Design: Cohort study; Level of evidence, 3.

Methods: A retrospective analysis was performed of patients who underwent arthroscopic rotator cuff repair between 2008 and 2012. We examined the …

Classifying Complications: Assessing Adult Spinal Deformity 2-Year Surgical Outcomes, Eric O. Klineberg, Munish Chandra Gupta, Et Al.

Open Access Publications

STUDY DESIGN: Retrospective review of prospective database.

OBJECTIVE: Complication rates for adult spinal deformity (ASD) surgery vary widely because there is no accepted system for categorization. Our objective was to identify the impact of complication occurrence, minor-major complication, and Clavien-Dindo complication classification (Cc) on clinical variables and patient-reported outcomes.

METHODS: Complications in surgical ASD patients with complete baseline and 2-year data were considered intraoperatively, perioperatively (<6 weeks), and postoperatively (>6 weeks). Primary outcome measures were complication timing and severity according to 3 scales: complication presence (yes/no), minor-major, and Cc score. Secondary outcomes were surgical outcomes (estimated blood loss [EBL], length of stay [LOS], …

Spontaneous Restoration Of Functional Β-Cell Mass In Obese Sm/J Mice, Mario A Miranda, Caryn Carson, Celine L St Pierre, Juan F Macias-Velasco, Jing W Hughes, Marcus Kunzmann, Heather Schmidt, Jessica P Wayhart, Heather A Lawson

Open Access Publications

Maintenance of functional β-cell mass is critical to preventing diabetes, but the physiological mechanisms that cause β-cell populations to thrive or fail in the context of obesity are unknown. High fat-fed SM/J mice spontaneously transition from hyperglycemic-obese to normoglycemic-obese with age, providing a unique opportunity to study β-cell adaptation. Here, we characterize insulin homeostasis, islet morphology, and β-cell function during SM/J's diabetic remission. As they resolve hyperglycemia, obese SM/J mice dramatically increase circulating and pancreatic insulin levels while improving insulin sensitivity. Immunostaining of pancreatic sections reveals that obese SM/J mice selectively increase β-cell mass but not α-cell mass. Obese SM/J …

Limb Lengthening In The Treatment Of Posteromedial Bowing Of The Tibia, J Eric Gordon, Perry L Schoenecker, Thomas R Lewis, Mark L Miller

Open Access Publications

PURPOSE: Posteromedial bowing of the tibia is an uncommon but recognized congenital lower extremity deformity in children that can lead to limb length discrepancy (LLD) and residual angulatory deformity. The purpose of this study is to report a series of children at a single institution with posteromedial bowing treated by lengthening.

METHODS: A retrospective review was carried out at our institution identifying 16 patients who were treated with limb lengthening for posteromedial bowing of the tibia and followed to skeletal maturity. Projected LLD was a mean of 7.7 cm (range 5.0 cm to 14.2 cm). Three patients were treated in …

Economic Evaluation Of The Specialized Donor Care Facility For Thoracic Organ Donor Management, Jason M. Gauthier, Maria B. Majella Doyle, William C. Chapman, Gary Marklin, Chad A. Witt, Elbert P. Trulock, Derek E. Byers, Ramsey R. Hachem, Michael K. Pasque, Bryan F. Meyers, G. Alexander Patterson, Ruben G. Nava, Benjamin D. Kozower, Daniel Kreisel, Su-Hsin Chang, Varun Puri

Open Access Publications

Background: Over the last decade two alternative models of donor care have emerged in the United States: the conventional model, whereby donors are managed at the hospital where brain death occurs, and the specialized donor care facility (SDCF), in which brain dead donors are transferred to a SDCF for medical optimization and organ procurement. Despite increasing use of the SDCF model, its cost-effectiveness in comparison to the conventional model remains unknown.

Methods: We performed an economic evaluation of the SDCF and conventional model of donor care from the perspective of U.S. transplant centers over a 2-year study period. In this …

It's Complicated: The Relationship Between Sleep And Alzheimer's Disease In Humans, Brendan P Lucey

Open Access Publications

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by an asymptomatic period of amyloid-β (Aβ) deposition as insoluble extracellular plaque, intracellular tau aggregation, neuronal and synaptic loss, and subsequent cognitive dysfunction and dementia. A growing public health crisis, the worldwide prevalence of AD is expected to rise from 46.8 million individuals affected in 2015 to 131.5 million in 2050. Sleep disturbances have been associated with increased future risk of AD. A bi-directional relationship is hypothesized between sleep and AD with sleep disturbances as either markers for AD pathology and/or a mechanism mediating increased risk of AD. In this review, …

Neurofibromatosis 1 - Mutant Microglia Exhibit Sexually-Dimorphic Cyclic Amp-Dependent Purinergic Defects, Nirmeen Elmadany, Francesca Logiacco, Alice Buonfiglioli, Verena C Haage, Elizabeth C Wright-Jin, Alexander Schattenberg, Roxane M Papawassiliou, Helmut Kettenmann, Marcus Semtner, David H Gutmann

Open Access Publications

As critical regulators of brain homeostasis, microglia are influenced by numerous factors, including sex and genetic mutations. To study the impact of these factors on microglia biology, we employed genetically engineered mice that model Neurofibromatosis type 1 (NF1), a disorder characterized by clinically relevant sexually dimorphic differences. While microglia phagocytic activity was reduced in both male and female heterozygous Nf1 mutant (Nf1+/-) mice, purinergic control of phagocytosis was only affected in male Nf1+/- mice. ATP-induced P2Y-mediated membrane currents and P2RY12-dependent laser lesion-induced accumulation of microglial processes were also only impaired in male, but not female Nf1+/-, microglia. These defects resulted …

A Molecular Understanding Of Alphavirus Entry, Autumn C. Holmes, Katherine Basore, Daved H. Fremont, Michael S. Diamond

Open Access Publications

Alphaviruses cause severe human illnesses including persistent arthritis and fatal encephalitis. As alphavirus entry into target cells is the first step in infection, intensive research efforts have focused on elucidating aspects of this pathway, including attachment, internalization, and fusion. Herein, we review recent developments in the molecular understanding of alphavirus entry both in vitro and in vivo and how these advances might enable the design of therapeutics targeting this critical step in the alphavirus life cycle.

Mechanisms Underlying Familial Aggregation Of Exceptional Health And Survival: A Three-Generation Cohort Study, Kaare Christensen, Mary K Wojczynski, Jacob K Pedersen, Lisbeth A Larsen, Susanne Kløjgaard, Axel Skytthe, Matt Mcgue, James W Vaupel, Michael A Province

Open Access Publications

The familial resemblance in length of adult life is very modest. Studies of parent-offspring and twins suggest that exceptional health and survival have a stronger genetic component than lifespan generally. To shed light on the underlying mechanisms, we collected information on Danish long-lived siblings (born 1886-1938) from 659 families, their 5379 offspring (born 1917-1982), and 10,398 grandchildren (born 1950-2010) and matched background population controls through the Danish 1916 Census, the Civil Registration System, the National Patient Register, and the Register of Causes of Death. Comparison with the background, population revealed consistently lower occurrence of almost all disease groups and causes …

Ss-31 And Nmn: Two Paths To Improve Metabolism And Function In Aged Hearts, Jeremy A Whitson, Alessandro Bitto, Huiliang Zhang, Mariya T Sweetwyne, Rene Coig, Saakshi Bhayana, Eric G Shankland, Lu Wang, Theo K Bammler, Kathryn F Mills, Shin-Ichiro Imai, Kevin E Conley, David J Marcinek, Peter S Rabinovitch

Open Access Publications

The effects of two different mitochondrial-targeted drugs, SS-31 and NMN, were tested on Old mouse hearts. After treatment with the drugs, individually or Combined, heart function was examined by echocardiography. SS-31 partially reversed an age-related decline in diastolic function while NMN fully reversed an age-related deficiency in systolic function at a higher workload. Metabolomic analysis revealed that both NMN and the Combined treatment increased nicotinamide and 1-methylnicotinamide levels, indicating greater NAD

Striatal Cholinergic Interneuron Numbers Are Increased In A Rodent Model Of Dystonic Cerebral Palsy, Sushma Gandham, Yearam Tak, Bhooma R Aravamuthan

Open Access Publications

Neonatal brain injury leading to cerebral palsy (CP) is the most common cause of childhood dystonia, a painful and functionally debilitating movement disorder. Rare monogenic etiologies of dystonia have been associated with striatal cholinergic interneuron (ChI) pathology. However it is unclear whether striatal ChI pathology is also associated with dystonia following neonatal brain injury. We used unbiased stereology to estimate striatal ChI and parvalbumin-positive GABAergic interneuron (PVI) numbers in a rodent model of neonatal brain injury that demonstrates electrophysiological markers of dystonia and spasticity. Striatal ChI numbers are increased following neonatal brain injury while PVI numbers are unchanged. These numbers …

High-Resolution Manometry Determinants Of Refractoriness Of Reflux Symptoms To Proton Pump Inhibitor Therapy, Mentore Ribolsi, Edoardo Savarino, Benjamin Rogers, Arvind Rengarajan, Marco Della Coletta, Matteo Ghisa, Michele Cicala, C Prakash Gyawali

Open Access Publications

Background/Aims: Impaired esophageal motility and disrupted esophagogastric junction (EGJ) on high-resolution manometry (HRM) have been associated with increased reflux severity in gastroesophageal reflux disease (GERD) patients. However, there are limited data evaluating HRM parameters in proton pump inhibitors (PPI) non-responders.

Methods: Clinical and endoscopic data, HRM and multichannel intraluminal impedance-pH studies performed of PPI therapy in patients with typical GERD symptoms were reviewed from 3 international centers. Frequency of GERD symptoms was assessed on and off PPI therapy in both non-responders (< 50% symptom improvement on PPI therapy) and responders. Rome IV definitions identified non-erosive reflux disease, reflux hypersensitivity, and functional heartburn. Univariate and multivariate analyses were performed to determine predictors of non-response.

Results: Of 204 patients, 105 were PPI non-responders and 99 were responders. Non-responders showed higher EGJ contractile integral …

Esophageal Baseline Impedance From High-Resolution Impedance Manometry Correlates With Mean Nocturnal Baseline Impedance From Ph-Impedance Monitoring, Anthony Horton, Brian Sullivan, Katie Charles, Thasha Mcintosh, Andrea Davis, Ziad Gellad, Rahul Shimpi, C Prakash Gyawali, Amit Patel

Open Access Publications

Background/Aims: Esophageal baseline impedance (BI) can be extracted from pH-impedance tracings as mean nocturnal baseline impedance (MNBI), and from high-resolution impedance manometry (HRIM), but it is unknown if values are similar between acquisition methods across HRIM manufacturers. We aim to assess correlations between MNBI and BI from HRIM (BI-HRIM) from 2 HRIM manufacturers in the setting of physiologic acid exposure time (AET).

Methods: HRIM and pH-impedance monitoring demonstrating physiologic AET (< 4%) off proton pump inhibitors were required. BI-HRIM was extracted as the average from 5 cm and 10 cm above the lower esophageal sphincter. Distal BI-HRIM (DBI-HRIM) was also extracted from the most distal channel (Medtronic studies). MNBI was extracted from 6 channels. Concordance between BI-HRIM across manufacturers with MNBI was analyzed.

Results: Thirty-six patients met the inclusion criteria (59.6 ± 1.7 years; 22% female; body mass index 30.5 ± 0.7; AET 1.6 ± 0.2%). Although MNBI was similar at all …

Five Years Of Ocrelizumab In Relapsing Multiple Sclerosis: Opera Studies Open-Label Extension, Stephen L Hauser, Robert T Naismith, Et Al

Open Access Publications

OBJECTIVE: To assess over 3 years of follow-up the effects of maintaining or switching to ocrelizumab (OCR) therapy on clinical and MRI outcomes and safety measures in the open-label extension (OLE) phase of the pooled OPERA: I/II studies in relapsing multiple sclerosis.

METHODS: After 2 years of double-blind, controlled treatment, patients continued OCR (600 mg infusions every 24 weeks) or switched from interferon (IFN)-β-1a (44 μg 3 times weekly) to OCR when entering the OLE phase (3 years). Adjusted annualized relapse rate, time to onset of 24-week confirmed disability progression (CDP)/improvement (CDP), brain MRI activity (gadolinium-enhanced and new/enlarging T2 lesions), …

Deep Learning Quantification Of Percent Steatosis In Donor Liver Biopsy Frozen Sections, Lulu Sun, Jon N Marsh, Matthew K Matlock, Ling Chen, Joseph P Gaut, Elizabeth M Brunt, S Joshua Swamidass, Ta-Chiang Liu

Open Access Publications

BACKGROUND: Pathologist evaluation of donor liver biopsies provides information for accepting or discarding potential donor livers. Due to the urgent nature of the decision process, this is regularly performed using frozen sectioning at the time of biopsy. The percent steatosis in a donor liver biopsy correlates with transplant outcome, however there is significant inter- and intra-observer variability in quantifying steatosis, compounded by frozen section artifact. We hypothesized that a deep learning model could identify and quantify steatosis in donor liver biopsies.

METHODS: We developed a deep learning convolutional neural network that generates a steatosis probability map from an input whole …

Integrase-Rna Interactions Underscore The Critical Role Of Integrase In Hiv-1 Virion Morphogenesis, Jennifer L. Elliott, Jenna E. Eschbach, Pratibha C. Koneru, Wen Li, Maritza Puray-Chavez, Dana Townsend, Dana Q. Lawson, Alan N. Engelman, Mamuka Kvaratskhelia, Sebla B. Kutluay

Open Access Publications

A large number of human immunodeficiency virus 1 (HIV-1) integrase (IN) alterations, referred to as class II substitutions, exhibit pleiotropic effects during virus replication. However, the underlying mechanism for the class II phenotype is not known. Here we demonstrate that all tested class II IN substitutions compromised IN-RNA binding in virions by one of the three distinct mechanisms: (i) markedly reducing IN levels thus precluding the formation of IN complexes with viral RNA; (ii) adversely affecting functional IN multimerization and consequently impairing IN binding to viral RNA; and (iii) directly compromising IN-RNA interactions without substantially affecting IN levels or functional …

Digenic Variants In The Fgf21 Signaling Pathway Associated With Severe Insulin Resistance And Pseudoacromegaly, Stephen I Stone, Daniel J Wegner, Jennifer A Wambach, F Sessions Cole, Fumihiko Urano, David M Ornitz

Open Access Publications

Insulin-mediated pseudoacromegaly (IMPA) is a rare disease of unknown etiology. Here we report a 12-year-old female with acanthosis nigricans, hirsutism, and acromegalic features characteristic of IMPA. The subject was noted to have normal growth hormone secretion, with extremely elevated insulin levels. Studies were undertaken to determine a potential genetic etiology for IMPA. The proband and her family members underwent whole exome sequencing. Functional studies were undertaken to validate the pathogenicity of candidate variant alleles. Whole exome sequencing identified monoallelic, predicted deleterious variants in genes that mediate fibroblast growth factor 21 (FGF21) signaling,

Incidence Of Uveitis And Macular Edema Among Patients Taking Fingolimod 0.5 Mg For Multiple Sclerosis., Scott Joseph Sonne, Bradley Thomas Smith

Open Access Publications

BACKGROUND: Patients with multiple sclerosis (MS) have a higher incidence of uveitis compared with the general population. Fingolimod, a first line disease modifying drug used in multiple sclerosis, may cause macular edema and thus requires ophthalmic examination. However, murine models and anecdotal reports suggest fingolimod may reduce the incidence of uveitis.

PURPOSE: To report the incidence of uveitis and macular edema among those on fingolimod 0.5 mg (Gilenya®) therapy for multiple sclerosis (MS).

METHODS: Retrospective review of patients on fingolimod who developed uveitis and/or macular edema.

RESULTS: No patients had an occurrence or history of uveitis. Four of the 188 …

Interplay Of Rfx Transcription Factors 1, 2 And 3 In Motile Ciliogenesis, Sylvain Lemeille, Marie Paschaki, Dominique Baas, Laurette Morlé, Jean-Luc Duteyrat, Aouatef Ait-Lounis, Emmanuèle Barras, Fabien Soulavie, Julie Jerber, Joëlle Thomas, Yong Zhang, Michael J. Holtzman, W Stephen Kistler, Walter Reith, Bénédicte Durand

Open Access Publications

Cilia assembly is under strict transcriptional control during animal development. In vertebrates, a hierarchy of transcription factors (TFs) are involved in controlling the specification, differentiation and function of multiciliated epithelia. RFX TFs play key functions in the control of ciliogenesis in animals. Whereas only one RFX factor regulates ciliogenesis in C. elegans, several distinct RFX factors have been implicated in this process in vertebrates. However, a clear understanding of the specific and redundant functions of different RFX factors in ciliated cells remains lacking. Using RNA-seq and ChIP-seq approaches we identified genes regulated directly and indirectly by RFX1, RFX2 and RFX3 …

Chamber-Specific Transcriptional Responses In Atrial Fibrillation, Catherine E Lipovsky, Jesus Jimenez, Qiusha Guo, Gang Li, Tiankai Yin, Stephanie C Hicks, Somya Bhatnagar, Kentaro Takahashi, David M Zhang, Brittany D Brumback, Uri Goldsztejn, Rangarajan D Nadadur, Carlos Perez-Cervantez, Ivan P Moskowitz, Shaopeng Liu, Bo Zhang, Stacey L Rentschler

Open Access Publications

Atrial fibrillation (AF) is the most common cardiac arrhythmia, yet the molecular signature of the vulnerable atrial substrate is not well understood. Here, we delineated a distinct transcriptional signature in right versus left atrial cardiomyocytes (CMs) at baseline and identified chamber-specific gene expression changes in patients with a history of AF in the setting of end-stage heart failure (AF+HF) that are not present in heart failure alone (HF). We observed that human left atrial (LA) CMs exhibited Notch pathway activation and increased ploidy in AF+HF but not in HF alone. Transient activation of Notch signaling within adult CMs in a …

Etv6 Germline Mutations Cause Hdac3/Ncor2 Mislocalization And Upregulation Of Interferon Response Genes, Marlie H Fisher, Gregory D Kirkpatrick, Brett Stevens, Courtney Jones, Michael Callaghan, Madhvi Rajpurkar, Joy Fulbright, Megan A Cooper, Jesse Rowley, Christopher C Porter, Arthur Gutierrez-Hartmann, Kenneth Jones, Craig Jordan, Eric M Pietras, Jorge Di Paola

Open Access Publications

ETV6 is an ETS family transcription factor that plays a key role in hematopoiesis and megakaryocyte development. Our group and others have identified germline mutations in ETV6 resulting in autosomal dominant thrombocytopenia and predisposition to malignancy; however, molecular mechanisms defining the role of ETV6 in megakaryocyte development have not been well established. Using a combination of molecular, biochemical, and sequencing approaches in patient-derived PBMCs, we demonstrate abnormal cytoplasmic localization of ETV6 and the HDAC3/NCOR2 repressor complex that led to overexpression of HDAC3-regulated interferon response genes. This transcriptional dysregulation was also reflected in patient-derived platelet transcripts and drove aberrant proplatelet formation …

Antimicrobial Resistance Surveillance In Low- And Middle-Income Countries: Progress And Challenges In Eight South Asian And Southeast Asian Countries, Sumanth Gandra, Gerardo Alvarez-Uria, Paul Turner, Jyoti Joshi, Direk Limmathurotsakul, H. Rogier Van Doorn

Open Access Publications

SUMMARYAntimicrobial resistance (AMR) is a serious global health threat and is predicted to cause significant health and economic impacts, particularly in low- and middle-income countries (LMICs). AMR surveillance is critical in LMICs due to high burden of bacterial infections; however, conducting AMR surveillance in resource-limited settings is constrained by poorly functioning health systems, scarce financial resources, and lack of skilled personnel. In 2015, the United Nations World Health Assembly endorsed the World Health Organization's Global Action Plan to tackle AMR; thus, several countries are striving to improve their AMR surveillance capacity, including making significant investments and establishing and expanding surveillance …

Endogenous Cyclin D1 Promotes The Rate Of Onset And Magnitude Of Mitogenic Signaling Via Akt1 Ser473 Phosphorylation, Ke Chen, Xuanmao Jiao, Agnese Di Rocco, Duanwen Shen, Shaohua Xu, Adam Ertel, Zuoren Yu, Gabriele Di Sante, Min Wang, Zhiping Li, Timothy G Pestell, Mathew C Casimiro, Emmanuel Skordalakes, Samuel Achilefu, Richard G Pestell

Open Access Publications

Cyclin D1 encodes the regulatory subunit of a holoenzyme that phosphorylates RB and functions as a collaborative nuclear oncogene. The serine threonine kinase Akt plays a pivotal role in the control of cellular metabolism, survival, and mitogenic signaling. Herein, Akt1-mediated phosphorylation of downstream substrates in the mammary gland is reduced by cyclin D1 genetic deletion and is induced by mammary-gland-targeted cyclin D1 overexpression. Cyclin D1 is associated with Akt1 and augments the rate of onset and maximal cellular Akt1 activity induced by mitogens. Cyclin D1 is identified in a cytoplasmic-membrane-associated pool, and cytoplasmic-membrane-localized cyclin D1-but not nuclear-localized cyclin D1-recapitulates Akt1 …

Open Access Publications

OBJECTIVE: To assess the effects of treatment with lurasidone on risk for metabolic syndrome (MetS) in patients with schizophrenia.

METHODS: Rates of metabolic syndrome during treatment with lurasidone (40-160 mg/d) were analyzed using pooled, short-term data from three randomized, double-blind, placebo-controlled studies (vs olanzapine and quetiapine XR); long-term data from two active-comparator-controlled studies (vs risperidone and quetiapine XR); and data from two open-label studies in which patients were switched from olanzapine or risperidone to lurasidone.

RESULTS: MetS was defined based on the National Cholesterol Education Program criteria. In short-term studies, the odds of meeting criteria for MetS at week 6 …

Covid-19 Hyperinflammation And Post-Covid-19 Illness May Be Rooted In Mast Cell Activation Syndrome, Lawrence B Afrin, Leonard B Weinstock, Gerhard J Molderings

Open Access Publications

OBJECTIVES: One-fifth of Covid-19 patients suffer a severe course of Covid-19 infection; however, the specific causes remain unclear. Mast cells (MCs) are activated by SARS-CoV-2. Although only recently recognized, MC activation syndrome (MCAS), usually due to acquired MC clonality, is a chronic multisystem disorder with inflammatory and allergic themes, and an estimated prevalence of 17%. This paper describes a novel conjecture explaining how MCAS might cause a propensity for severe acute Covid-19 infection and chronic post-Covid-19 illnesses.

METHODS: Observations of Covid-19 illness in patients with/without MCAS were compared with extensive clinical experience with MCAS.

RESULTS: The prevalence of MCAS is …
