Nursing practice is informed by research, and all nurses, midwives and care staff should be research aware even if they do not consider themselves research active. The principles of research ethics, based on respect for individuals, should not be confined to research. All nurses must be aware of these principles, and practise in accordance with them.
View Article and Find Full Text PDFBackground: Routinely collected electronic patient records are already widely used in epidemiological research. In this work we investigated the potential for using them to identify endpoints in clinical trials.
Methods: The events recorded in the West of Scotland Coronary Prevention Study (WOSCOPS), a large clinical trial of pravastatin in middle-aged hypercholesterolaemic men in the 1990s, were compared with those in the record-linked deaths and hospitalisations records routinely collected in Scotland.
The implementation of a pharmacovigilance service compliant with the legal and regulatory responsibilities of clinical trial sponsors presents particular challenges for sponsors in a non-commercial setting.In this paper we examine these challenges in detail. We identify and discuss the key steps in the development of a pharmacovigilance service within a public health service and university setting in the United Kingdom.

Henry K. Beecher and Maurice H. Pappworth were the 2 most prominent medical whistleblowers in research ethics of the 20th century.

ACTFAST was a 12-week prospective, open-label study in patients at high risk for atherosclerosis (European origin, n = 1978; South Asian origin, n = 64). Compared with patients of European origin, patients of South Asian origin were younger, were less likely to smoke, and had lower body mass index, systolic blood pressure, low-density lipoprotein cholesterol (LDL-C) and triglycerides.

The methods that are utilised to assess data quality and the results of any reviews undertaken are rarely reported in the literature. We have recently undertaken a quality review of trial data submitted to a Clinical Endpoint Committee for adjudication.

It has been suggested that statins might reduce the risk of VTE however positive results from studies of middle aged subjects may not be generalisable to elderly people. We aimed to determine the effect of pravastatin on incident VTE in older people; we also studied the impact of clinical and plasma risk variables.

We evaluated the association of Lp-PLA(2) with vascular events in the elderly where the importance of LDL is diminished as a risk factor for coronary disease.
Methods: Mass and activity of Lp-PLA(2) were related to risk over 3.
Aim And Objective: The accuracy with which patients recall their cardiac symptoms prior to aorta-coronary artery bypass grafting is assessed approximately one year after surgery together with patient-related factors potentially influencing accuracy of recall.
Background: This is a novel investigation of patient's rating of preoperative symptom severity before and approximately one year following aorta-coronary artery bypass grafting.
Design: Patients undergoing aorta-coronary artery bypass grafting (n = 208) were recruited preoperatively and 177 of these were successfully followed up at 16.
The CD40/CD40 ligand plays a role in the inflammatory and prothrombotic processes in atherosclerosis. We analyzed whether short-term treatment with atorvastatin affects soluble CD40 ligand (sCD40L) plasma levels in subjects at high cardiovascular risk. sCD40L plasma concentrations were measured in 852 subjects from the Atorvastatin on Inflammatory Markers (AIM) Study, a 12-week prospective multicenter, open-label trial which enrolled statin-free subjects with coronary heart disease (CHD), CHD-equivalent (diabetes, peripheral vascular disease, or cerebrovascular disease), or a 10-year CHD risk >20%.

Methods: Two 12-week, prospective, open-label trials enrolled 2717 high-risk subjects, of whom 1024 had diabetes and 1251 had metabolic syndrome. Subjects with LDL-C between 100 and 220 mg/dL (2.

Adiponectin can suppress atherogenesis by inhibiting the adherence of monocytes, reducing their phagocytic activity, and suppressing the accumulation of modified lipoproteins in the vascular wall. Contradictory data have been reported about the effect of statins on adiponectin plasma levels. In this work, adiponectin plasma levels were measured in 102 statin-free subjects from the Spanish population of the Achieve Cholesterol Targets Fast with Atorvastatin Stratified Titration (ACTFAST) study, a 12-week, prospective, multi-centre, open-label trial which enrolled subjects with coronary heart disease, coronary heart disease-equivalent or a 10-year coronary heart disease risk >20%.

Design: Prospective study.
Setting: Scotland, Ireland, and the Netherlands.
Background: Plasma levels of soluble intercellular adhesion molecule 1 (sICAM-1) and monocyte chemoattractant protein 1 (sMCP-1) are associated with increased risk for future coronary events. However, the effect of statins on these inflammatory markers has hardly been studied. We analyzed whether treatment with the different doses of atorvastatin affects sICAM-1 and sMCP-1 plasma levels in subjects at high cardiovascular risk.

Changes in parameters for 86 men who converted to new-onset diabetes ("converters": two consecutive glucose levels > or =7 mmol/l) were compared with 860 "nonconverters" matched for age and treatment allocation. Eighteen months before the diagnosis, converters to diabetes had elevated (P < 0.

Methods And Results: Baseline CRP was related to risk over 3.
Objective: Increasing evidence indicates that the Fas/Fas ligand interaction is involved in atherogenesis. We sought to analyze soluble Fas (sFas) and soluble Fas ligand (sFasL) concentrations in subjects at high cardiovascular risk and their modulation by atorvastatin treatment.
Methods And Results: ACTFAST was a 12-week, prospective, multicenter, open-label trial which enrolled subjects (statin-free or statin-treated at baseline) with coronary heart disease (CHD), CHD-equivalent, or 10-year CHD risk > 20%.
