Stroke

October 2014

From the Stroke Research Group, Department of Brain Repair and Rehabilitation, National Hospital for Neurology and Neurosurgery (A.C., D.J.W.), Lysholm Department of Neuroradiology, National Hospital for Neurology and Neurosurgery (R.H.J.), and Department of Brain Repair and Rehabilitation (R.H.J.), UCL Institute of Neurology, London, United Kingdom; Department of Neurology, Cliniques Universitaires UCL Saint Luc, Brussels, Belgium (A.P.); Department of Neurology, CHU Dinant Godinne (Y.V., P.L.) and Institute of Neuroscience (Y.V., P.L.), Université Catholique de Louvain, Brussels, Belgium; Department of Clinical Neurosciences, University of Cambridge, Addenbrooke's Hospital, Cambridge, United Kingdom (J.-C.B.); and UMR 894 INSERM-Université Paris 5, Sorbonne Paris Cité, Paris, France (J.-C.B.).

Background And Purpose: We set out to investigate whether MRI-visible centrum semiovale perivascular spaces (CSO-PVS), a potential biomarker of impaired interstitial fluid drainage in sporadic cerebral amyloid angiopathy, is associated with cortical superficial siderosis (cSS), reflecting recurrent hemorrhage from severe leptomeningeal and superficial cortical vascular amyloid.

Methods: Retrospective multicenter cohort study of possible/probable cerebral amyloid angiopathy according to the Boston criteria. PVS were rated in basal ganglia and CSO (CSO-PVS) on axial T2-weighted sequences, using a validated 4-point visual rating scale and were classified as high (score>2) or low degree (score≤2) for prespecified analyses.

Background And Purpose: In the early days after ischemic stroke, information on structural brain damage from MRI supports prognosis of functional outcome. It is rated widely by the modified Rankin Scale that correlates only moderately with lesion volume. We therefore aimed to elucidate the influence of lesion location from early MRI (days 2-3) on functional outcome after 1 month using voxel-based lesion symptom mapping.

Article Synopsis
  • Researchers analyzed data from 14 studies involving nearly 27,000 participants to find genetic factors influencing the levels of tissue plasminogen activator (tPA), a key enzyme in blood clot breakdown.
  • They identified three significant genetic loci associated with tPA levels: one linked to the STXBP5 gene on chromosome 6, another near the PLAT gene on chromosome 8, and a third related to the STX2 gene on chromosome 12.
  • Functional tests showed that silencing STXBP5 reduces tPA release from cells, while silencing STX2 increases it, suggesting these genes play important roles in regulating tPA levels.

Background: Patients with relapsed chronic lymphocytic leukemia (CLL) who have clinically significant coexisting medical conditions are less able to undergo standard chemotherapy. Effective therapies with acceptable side-effect profiles are needed for this patient population.

Methods: In this multicenter, randomized, double-blind, placebo-controlled, phase 3 study, we assessed the efficacy and safety of idelalisib, an oral inhibitor of the delta isoform of phosphatidylinositol 3-kinase, in combination with rituximab versus rituximab plus placebo.

Background And Purpose: Genome-wide association studies have revealed multiple common variants associated with known risk factors for ischemic stroke (IS). However, their aggregate effect on risk is uncertain. We aimed to generate a multilocus genetic risk score (GRS) for IS based on genome-wide association studies data from clinical-based samples and to establish its external validity in prospective population-based cohorts.

A molecular marker of artemisinin-resistant Plasmodium falciparum malaria.

Nature

January 2014

1] Institut Pasteur du Cambodge, Malaria Molecular Epidemiology Unit, Phnom Penh, Cambodia [2].

Plasmodium falciparum resistance to artemisinin derivatives in southeast Asia threatens malaria control and elimination activities worldwide. To monitor the spread of artemisinin resistance, a molecular marker is urgently needed. Here, using whole-genome sequencing of an artemisinin-resistant parasite line from Africa and clinical parasite isolates from Cambodia, we associate mutations in the PF3D7_1343700 kelch propeller domain ('K13-propeller') with artemisinin resistance in vitro and in vivo.

Background And Purpose: Ischemic stroke (IS) and coronary artery disease (CAD) share several risk factors and each has a substantial heritability. We conducted a genome-wide analysis to evaluate the extent of shared genetic determination of the two diseases.

Methods: Genome-wide association data were obtained from the METASTROKE, Coronary Artery Disease Genome-wide Replication and Meta-analysis (CARDIoGRAM), and Coronary Artery Disease (C4D) Genetics consortia.

Impact of physiologically based pharmacokinetic modeling and simulation in drug development.

Drug Metab Dispos

Department of Drug Metabolism and Pharmacokinetics, GlaxoSmithKline, Ware, Hertfordshire, United Kingdom (C.E.S., A.H.P., J.C.B.), King of Prussia, Pennsylvania (T.T., G.T.), and Research Triangle Park, North Carolina (G.T.G.).

Physiologically based pharmacokinetic modeling and simulation can be used to predict the pharmacokinetics of drugs in human populations and to explore the effects of varying physiologic parameters that result from aging, ethnicity, or disease. In addition, the effects of concomitant medications on drug exposure can be investigated; prediction of the magnitude of drug interactions can impact regulatory communications or internal decision-making regarding the requirement for a clinical drug interaction study. Modeling and simulation can also help to inform the design and timings of clinical drug interaction studies, resulting in more efficient use of limited resources and improved planning in addition to promoting mechanistic understanding of observed drug interactions.
