Our study showed equipoise between oral vancomycin therapy (OVT) at 1500mg/day in patients >30kg, ursodeoxycholic acid (UDCA), and untreated observation. Children with the mildest disease as measured by the Sclerosing Cholangitis Outcomes in PEdiatrics (SCOPE) index(1) demonstrated the highest rates of biochemical improvement, regardless of management strategy. These data challenge the assumption that biomarkers like GGT rise progressively from diagnosis until end stage liver disease, and improve only with medication. Read More

CHARGE syndrome in the era of molecular diagnosis: Similar outcomes in those without coloboma or choanal atresia.

Eur J Med Genet 2021 Jan 12;64(1):104103. Epub 2020 Nov 12.

Cincinnati Children's Hospital Medical Center: Division of Human Genetics, United States; Cincinnati Children's Hospital Medical Center: Department of Pediatrics, University of Cincinnati College of Medicine, United States.

CHARGE syndrome (OMIM 214800) is a condition characterized by multisystem involvement with CHD7 pathogenic mutations leading to disease in the majority of patients. Discovery of the molecular cause of CHARGE unmasked a larger phenotypic spectrum than was previously appreciated. Within our interdisciplinary CHARGE syndrome program, we sought to characterize our CHD7-positive CHARGE cohort without coloboma or choanal atresia, highlighting complications and outcomes.

Comparative assessment of multiple COVID-19 serological technologies supports continued evaluation of point-of-care lateral flow assays in hospital and community healthcare settings.

PLoS Pathog 2020 09 24;16(9):e1008817. Epub 2020 Sep 24.

Department of Infectious Diseases, School of Immunology & Microbial Sciences, King's College London, London, United Kingdom.

There is a clear requirement for an accurate SARS-CoV-2 antibody test, both as a complement to existing diagnostic capabilities and for determining community seroprevalence. We therefore evaluated the performance of a variety of antibody testing technologies and their potential use as diagnostic tools. Highly specific in-house ELISAs were developed for the detection of anti-spike (S), -receptor binding domain (RBD) and -nucleocapsid (N) antibodies and used for the cross-comparison of ten commercial serological assays-a chemiluminescence-based platform, two ELISAs and seven colloidal gold lateral flow immunoassays (LFIAs)-on an identical panel of 110 SARS-CoV-2-positive samples and 50 pre-pandemic negatives.

Association between asthma, corticosteroids and allostatic load biomarkers: a cross-sectional study.

Thorax 2020 10 12;75(10):835-841. Epub 2020 Aug 12.

Centre for Infection and Immunity, Queen's University Belfast, Belfast, UK

Background: Allostatic load, a measure of early ageing or 'wear and tear' from adapting to environmental challenges, has been suggested as a framework with which to understand the stress-related disruption of multiple biological systems which may be linked to asthma. Considering the socioeconomic context is also critical given asthma and allostatic overload are more common in lower socioeconomic groups.

Aims: Estimate the relationship between allostatic load and its constituent biomarkers, asthma and corticosteroid prescribing while controlling for socioeconomic status. Read More

The Identification of Novel Biomarkers Is Required to Improve Adult SMA Patient Stratification, Diagnosis and Treatment.

J Pers Med 2020 Jul 29;10(3). Epub 2020 Jul 29.

Centre of Research in Myology, Institute of Myology, Sorbonne Université, INSERM, 75013 Paris, France.

Spinal muscular atrophy (SMA) is currently classified into five different subtypes, from the most severe (type 0) to the mildest (type 4) depending on age at onset, best motor function achieved, and copy number of the gene. The two recent approved treatments for SMA patients revolutionized their life quality and perspectives. However, upon treatment with Nusinersen, the most widely administered therapy up to date, a high degree of variability in therapeutic response was observed in adult SMA patients. Read More

Homocysteic Acid in Blood Can Detect Mild Cognitive Impairment: A Preliminary Study.

J Alzheimers Dis 2020 ;77(2):773-780

KUDOH Clinic for Neurosurgery and Neurology, Ota-ku, Tokyo, Japan.

Background: In the treatment of Alzheimer's disease (AD), it is thought to be most effective to intervene at the earliest and mildest stages. For diagnosis at the earliest and mildest stages, it is desirable to use a biomarker that can be detected by a minimally invasive, cost-effective technique. Recent research indicates the potential clinical usefulness of plasma amyloid-β (Aβ) biomarkers in predicting brain Aβ burden at an individual level. Read More

Extension of the phenotypic spectrum of GLE1-related disorders to a mild congenital form resembling congenital myopathy.

Mol Genet Genomic Med 2020 08 14;8(8):e1277. Epub 2020 Jun 14.

GIPTIS (Genetics Institute for Patients, Therapies Innovation and Science), Marseille, France.

Background: GLE1 (GLE1, RNA Export Mediator, OMIM#603371) variants are associated with severe autosomal recessive motor neuron diseases, that are lethal congenital contracture syndrome 1 (LCCS1, OMIM#253310) and congenital arthrogryposis with anterior horn cell disease (CAAHD, OMIM#611890). The clinical spectrum of GLE1-related disorders has been expanding these past years, including with adult-onset amyotrophic lateral sclerosis (ALS) GLE1-related forms, especially through the new molecular diagnosis strategies associated with the emergence of next-generation sequencing (NGS) technologies. However, despite this phenotypic variability, reported congenital or ALS adult-onset forms remain severe, leading to premature death. Read More

"Can do, don't do" are not the lazy ones: a longitudinal study on physical functioning in patients with COPD.

Respir Res 2020 Jan 20;21(1):27. Epub 2020 Jan 20.

Pulmonary Division, University Hospital Zurich, Raemistrasse 100, 8091, Zurich, Switzerland.
