Frailty and Mortality Outcomes After Percutaneous Coronary Intervention: A Systematic Review and Meta-Analysis.
2017
Abstract Background Frailty has been identified as a risk factor for mortality. However, whether frailty increases mortality risk in patients undergoing percutaneous coronary intervention (PCI) has been controversial. Therefore, we conducted a systematic review and meta-analysis of the frailty measures and mortality outcomes in this setting. Methods PubMed and EMBASE were searched until July 23, 2017 for studies evaluating the association between frailty measures and mortality in individuals who have undergone PCI. Results A total of 141 entries were retrieved from our search strategy. A total of 8 studies involving 2332 patients were included in the final meta-analysis (mean age: 69 years;…

Intracerebral Hemorrhage and Outcome After Thrombolysis in Stroke Patients Using Selective Serotonin-Reuptake Inhibitors.
2017
Background and Purpose— Selective serotonin-reuptake inhibitors (SSRIs) impair platelet function and have been linked to a higher risk of spontaneous intracerebral hemorrhage—an association that may be augmented by oral anticoagulants (OAC). We aimed to assess whether preadmission treatment with SSRIs in patients with acute ischemic stroke is associated with post-thrombolysis symptomatic intracerebral hemorrhage (sICH) and functional outcome. Methods— A multicenter retrospective analysis was conducted in prospective registries of patients treated by thrombolysis within 4.5 hours of stroke onset. The association between preadmission treatment with SSRIs and sICH (ECASS II definition [Europe…
Bloodstream Infections in Hospitalized Patients with COVID-19: A Systematic Review and Meta-Analysis
2021
Background: Little is known about the occurrence of bloodstream infections in hospitalized patients with COVID-19 and the related clinical consequences. The aim of this systematic review and meta-analysis was to estimate the pooled occurrence of BSIs among hospitalized patients with COVID-19 and mortality of this patient population. Methods: A systematic search was performed on PubMed, EMBASE, and Web of Science from inception to 19 April 2021. The primary outcome was the occurrence of BSIs among hospitalized patients with COVID-19. The secondary outcome was mortality at the longest available follow-up. Results: Forty-six studies met the inclusion criteria, with a total of 42,694 patients e…
Psychiatric genome-wide association study analyses implicate neuronal, immune and histone pathways
2015
G.B. and S.N. acknowledge funding support for this work from the National Institute for Health Research (NIHR) Mental Health Biomedical Research Centre at South London and Maudsley NHS Foundation Trust and King's College London. P.H.L. is supported by US National Institute of Mental Health (NIMH) grant K99MH101367. Genome-wide association studies (GWAS) of psychiatric disorders have identified multiple genetic associations with such disorders, but better methods are needed to derive the underlying biological mechanisms that these signals indicate. We sought to identify biological pathways in GWAS data from over 60,000 participants from the Psychiatric Genomics Consortium. We developed an an…

Large characteristically simple sections of finite groups
2021
In this paper we prove that if G is a group for which there are k non-Frattini chief factors isomorphic to a characteristically simple group A, then G has a normal section C/R that is the direct product of k minimal normal subgroups of G/R isomorphic to A. This is a significant extension of the notion of crown for isomorphic chief factors.
Characterizations of Schunck Classes of Finite Soluble Groups
1998
All groups considered in this paper are finite and soluble.Characterization of Schunck classes and saturated formations by meansof certain embedding properties of their associated projectors plays animportant part in the Theory of Classes of Groups.Schunck classes whose projectors are normal subgroups were studied byBlessenohl and Gaschutz. They characterize these classes as the classes
Permutable subnormal subgroups of finite groups
2009
The aim of this paper is to prove certain characterization theorems for groups in which permutability is a transitive relation, the so called PT -groups. In particular, it is shown that the finite solvable PT -groups, the finite solvable groups in which every subnormal subgroup of defect two is permutable, the finite solvable groups in which every normal subgroup is permutable sensitive, and the finite solvable groups in which conjugatepermutability and permutability coincide are all one and the same class. This follows from our main result which says that the finite modular p-groups, p a prime, are those p-groups in which every subnormal subgroup of defect two is permutable or, equivalentl…
