BACKGROUND: Loss-of-function mutations in the LDL (low-density lipoprotein) receptor gene (METHODS: We analyzed whole-genome sequencing data from 43 202 Icelanders. Single-nucleotide polymorphisms and structural variants including deletions, insertions, and duplications were genotyped using whole-genome sequencing-based data. LDL cholesterol associations...

Dopamine-related striatal neurophysiology is associated with specialization of frontostriatal reward circuitry through adolescence.

Progress in neurobiology

Prog Neurobiol. 2021 Jun;201:101997. doi: 10.1016/j.pneurobio.2021.101997. Epub 2021 Mar 02.

Characterizing developmental changes in frontostriatal circuitry is critical to understanding adolescent development and can clarify neurobiological mechanisms underlying increased reward sensitivity and risk-taking and the emergence of psychopathology during this period. However, the role of striatal neurobiology in the...

Intraventricular Vancomycin Treatment for Shunt-related Ventriculitis Caused by Methicillin-resistant Staphylococcus Aureus in a Preterm Infant: A Case Report.

The Pediatric infectious disease journal

Helgason EA, Oskarsdottir T, Brynjarsson H, Olafsson IH, Thors V.

Pediatr Infect Dis J. 2021 Nov 26; doi: 10.1097/INF.0000000000003403. Epub 2021 Nov 26.

Posthemorragic hydrocephalus is a relatively common condition in prematures, often requiring ventriculoperitoneal shunts. We report a case of methicillin-resistant Staphylococcus aureus infection of a ventriculoperitoneal shunt in a premature neonate which failed conventional intravenous treatment. Despite the absence of...

Exploration of Functional Connectivity Changes Previously Reported in Fibromyalgia and Their Relation to Psychological Distress and Pain Measures.

Journal of clinical medicine

van Ettinger-Veenstra H, Boehme R, Ghafouri B, Olausson H, Wicksell RK, Gerdle B.
PMID: 33167371
J Clin Med. 2020 Nov 05;9(11). doi: 10.3390/jcm9113560.

Neural functional connectivity changes in the default mode network (DMN), Central executive network (CEN), and insula have been implicated in fibromyalgia (FM) but stem from a sparse set of small-scale studies with limited power for the investigation of confounding...

Toxoplasma gondii exploits the host ESCRT machinery for parasite uptake of host cytosolic proteins.

PLoS pathogens

Rivera-Cuevas Y, Mayoral J, Di Cristina M, Lawrence AE, Olafsson EB, Patel RK, Thornhill D, Waldman BS, Ono A, Sexton JZ, Lourido S, Weiss LM, Carruthers VB.

PLoS Pathog. 2021 Dec 13;17(12):e1010138. doi: 10.1371/journal.ppat.1010138. eCollection 2021 Dec.

Toxoplasma gondii is a master manipulator capable of effectively siphoning the resources from the host cell for its intracellular subsistence. However, the molecular underpinnings of how the parasite gains resources from its host remain largely unknown. Residing within a...

A validation study of an esophageal probe-based polygraph against polysomnography in obstructive sleep apnea.

Sleep & breathing = Schlaf & Atmung

Olafsson TA, Steinsvik EA, Bachmann-Harildstad G, Hrubos-Strøm H.
PMID: 34181175
Sleep Breath. 2021 Jun 28; doi: 10.1007/s11325-021-02374-4. Epub 2021 Jun 28.

STUDY OBJECTIVES: The aim of this study was to validate the automatically scored results of an esophageal probe-based polygraph system (ApneaGraph® Spiro) against manually scored polysomnography (Nox A1, PSG) results. We compared the apnea-hypopnea index, oxygen saturation index, and...

Monoclonal gammopathy of undetermined significance and COVID-19: a population-based cohort study.

Multiple myeloma (MM) patients have increased risk of severe coronavirus disease 2019 (COVID-19) when infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Monoclonal gammopathy of undetermined significance (MGUS), the precursor of MM has been associated with immune dysfunction...
