Addition of docetaxel or bisphosphonates to standard of care in men with localised or metastatic, hormone-sensitive prostate cancer: a systematic review and meta-analyses of aggregate data

Abstract: Summary Background Results from large randomised controlled trials combining docetaxel or bisphosphonates with standard of care in hormone-sensitive prostate cancer have emerged. In order to investigate the effects of these therapies and to respond to emerging evidence, we aimed to systematically review all relevant trials using a framework for adaptive meta-analysis. Methods For this systematic review and meta-analysis, we searched MEDLINE, Embase, LILACS, and the Cochrane Central Register of Controlled Trials, trial registers, conference proceedings, review articles, and reference lists of trial publications for all relevant randomised controlled trials (published, unpublished, and ongoing) comparing either standard of care with or without docetaxel or standard of care with or without bisphosphonates for men with high-risk localised or metastatic hormone-sensitive prostate cancer. For each trial, we extracted hazard ratios (HRs) of the effects of docetaxel or bisphosphonates on survival (time from randomisation until death from any cause) and failure-free survival (time from randomisation to biochemical or clinical failure or death from any cause) from published trial reports or presentations or obtained them directly from trial investigators. HRs were combined using the fixed-effect model (Mantel-Haenzsel). Findings We identified five eligible randomised controlled trials of docetaxel in men with metastatic (M1) disease. Results from three (CHAARTED, GETUG-15, STAMPEDE) of these trials (2992 [93%] of 3206 men randomised) showed that the addition of docetaxel to standard of care improved survival. The HR of 0·77 (95% CI 0·68–0·87; p Interpretation The addition of docetaxel to standard of care should be considered standard care for men with M1 hormone-sensitive prostate cancer who are starting treatment for the first time. More evidence on the effects of docetaxel on survival is needed in the M0 disease setting. No evidence exists to suggest that zoledronic acid improves survival in men with M1 or M0 disease, and any potential benefit is probably small. Funding Medical Research Council UK.

Theorising inequalities in health : the place of lay knowledge.

Abstract: This paper contributes to the development of theory and research on inequalities in health. Our central premise is that these are currently limited because they fail adequately to address the relationship between agency and structure, and that lay knowledge in the form of narrative has a significant contribution to make to this endeavour. The paper is divided into three sections. In the first section we briefly review the existing, largely quantitative research on inequalities in health. We then move on to consider some of the most significant critiques of this body of work highlighting three issues: the pursuit of overly simple unidimensional explanations within 'risk factor' epidemiology and the (probably inevitable) inability of this research tradition to encompass the full complexity of social processes; the failure to consider the social context of individual behaviour and, in particular, the possibility for, and determinants of, creative human agency; and, thirdly, the need for 'place' and 'time' (both historical and biographical) to be given greater theoretical prominence. In the final section of the paper the potential theoretical significance of 'place' and 'lay knowledge', and the relationship between these concepts, in inequalities research is explored. Here we suggest three developments as a necessary condition for a more adequate theoretical framework in this field. We consider first the need for the conceptualisation and measurement of 'place' within a historical context, as the location in which macro social structures impact on people's lives. Second, we argue for a re-conceptualisation of lay knowledge about everyday life in general and the nature and causes of health and illness in particular, as narratives which have embedded within them explanations for what people do and why – and which, in turn, shape social action. Finally, we suggest that this narrative knowledge is also the medium through which people locate themselves within the places they inhabit and determine how to act within and upon them. Lay knowledge therefore offers a vitally important but neglected perspective on the relationship between social context and the experience of health and illness at the individual and population level.

The PERMIS X.509 role based privilege management infrastructure

Abstract: This paper describes the output of the PERMIS project, which has developed a role based access control infrastructure that uses X.509 attribute certificates (ACs) to store the users' roles. All access control decisions are driven by an authorization policy, which is itself stored in an X.509 attribute certificate, thus guaranteeing its integrity. All the ACs can be stored in one or more LDAP directories, thus making them widely available. Authorization policies are written in XML according to a DTD that has been published at XML.org. The Access Control Decision Function (ADF) is written in Java and the Java API is simple to use, comprising of just 3 methods and a constructor. There is also a Privilege Allocator, which is a tool that constructs and signs attribute certificates and stores them in an LDAP directory for subsequent use by the ADF.

Detection of Atrial Fibrillation After Ischemic Stroke or Transient Ischemic Attack A Systematic Review and Meta-Analysis

Abstract: Background and Purpose—Atrial fibrillation (AF) confers a high risk of recurrent stroke, although detection methods and definitions of paroxysmal AF during screening vary. We therefore undertook a systematic review and meta-analysis to determine the frequency of newly detected AF using noninvasive or invasive cardiac monitoring after ischemic stroke or transient ischemic attack. Methods—Prospective observational studies or randomized controlled trials of patients with ischemic stroke, transient ischemic attack, or both, who underwent any cardiac monitoring for a minimum of 12 hours, were included after electronic searches of multiple databases. The primary outcome was detection of any new AF during the monitoring period. We prespecified subgroup analysis of selected (prescreened or cryptogenic) versus unselected patients and according to duration of monitoring. Results—A total of 32 studies were analyzed. The overall detection rate of any AF was 11.5% (95% confidence interval, 8.9%–14.3%), although the ti...

The Prevalence of Foot Ulceration and its Correlates in Type 2 Diabetic Patients: a Population-based Study

Abstract: The prevalence of peripheral neuropathy, peripheral vascular disease, and foot ulceration in Type 2 diabetic patients in the community were determined in a community-based study. Eight hundred and eleven subjects (404 male, 407 female, mean age 65.4 (range 34-90) years, diabetes duration 7.4 (0-50) years) from 37 general practices in three UK cities were studied. Neuropathy was diagnosed clinically using modified neuropathy disability scores which were ascertained using structured interviews and clinical examinations by one observer in each city. Peripheral vascular disease was diagnosed if a history of revascularization was present or > or = 2 foot pulses were absent. History of current or previous foot ulceration was recorded. The prevalence of neuropathy was 41.6% (95% confidence limits 38.3-44.9%) and the prevalence of PVD, 11% (9.1-13.7%). Forty-eight percent of neuropathic patients reported significant neuropathic symptoms. Forty-three patients (5.3% (3.8-6.8%)) had current or past foot ulcers; 20 of these were pure neuropathic ulcers, 13 neuroischaemic, 5 pure vascular, and 5 were unclassified. Multiple logistic regression showed history of amputation, neuropathy disability score, and peripheral vascular disease to be significantly associated with foot ulceration after adjusting for age and diabetes duration. A substantial proportion of Type 2 diabetic patients, often elderly patients who do not attend hospitals, suffered from peripheral neuropathy and peripheral vascular disease. These patients are at risk of foot ulceration and may benefit from preventive footcare.
