BACKGROUND Despite increasing international interest, there is a lack of evidence about the most efficient, effective and acceptable ways to implement patient and public involvement (PPI) in clinical trials. OBJECTIVE To identify the priorities of UK PPI stakeholders for methodological research to help resolve uncertainties about PPI in clinical trials. DESIGN A modified Delphi process incl...
Use-dependent N-methyl-d-aspartate receptor (NMDAR) antagonists produce behaviors in human volunteers that resemble schizophrenia and exacerbate those behaviors in schizophrenic patients, suggesting that hypofunction of NMDAR-mediated neuronal circuitry may be involved in the etiology of clinical schizophrenia. Activation of the metabotropic glutamate receptor subtype 5 (mGluR5) enhances NMDAR-...
Concomitant proton pump inhibitor (PPI) use reduces plasma concentrations of certain nonstructural protein 5A inhibitors, which are key components of modern hepatitis C infection (HCV) treatments. These reduced concentrations may decrease efficacy, leading to challenging treatment failures due to the development of resistance-associated substitutions. This post-hoc analysis assessed 12-week sus...
BACKGROUND Aspirin, when used with concurrent anticoagulation, increases the risk of gastrointestinal bleeding (GIB). Therefore, multisociety guidelines recommend prophylactic proton-pump inhibitors (PPIs) for patients receiving aspirin and anticoagulation. We aimed to determine rates and predictors of adherence to these recommendations. METHODS All adult inpatients discharged from the hospit...
Neural regions modulating prepulse inhibition (PPI) of the startle response, an operational measure of sensorimotor gating, are well established from animal studies using surgical and pharmacological procedures. The limbic and cortico-pallido-striato-thalamic circuitry is thought to be responsible for modulation of PPI in the rat. The involvement of this circuitry in human PPI is suggested by o...
There is huge commitment to public and patient involvement (PPI) in UK clinical research. Despite there being wide agreement to practice PPI and national guidance on the subject, there are few practical examples of how to implement PPI and few published models to demonstrate how it can be achieved consistently and constructively across a broad portfolio of studies. The Peninsula Research Bank d...
OBJECTIVE Patient and public involvement (PPI) has become an established theme within the UK health research policy and is recognised as an essential force in the drive to improve the quality of services and research. These developments have been particularly rapid in the cancer field. METHODS This paper outlines a model of PPI in research (known as the North Trent Cancer Research Network Con...
OBJECTIVES The purpose of this study was to evaluate the prevalence and mechanism of a misleading long post-pacing interval (PPI) upon entrainment of typical atrial flutter (AFL) from the cavotricuspid isthmus (CTI). BACKGROUND In typical AFL, the PPI from entrainment at the CTI is expected to closely match the tachycardia cycle-length (TCL). METHODS Sixty patients with confirmed CTI-depend...
