Frequently, a set of objects has to be evaluated by a panel of assessors, but not every object is assessed by every assessor. A problem facing such panels is how to take into account different standards among panel members and varying levels of confidence in their scores. Here, a mathematically based algorithm is developed to calibrate the scores of such assessors, addressing both of these issues. The algorithm is based on the connectivity of the graph of assessors and objects evaluated, incorporating declared confidences as weights on its edges...

Like most work systems, the domain of adventure activities has seen a series of serious incidents and subsequent calls to improve regulation. Safety regulation systems aim to promote safety and reduce accidents. However, there is scant evidence they have led to improved safety outcomes. In fact there is some evidence that the poor integration of regulatory system components has led to adverse safety outcomes in some contexts. Despite this, there is an absence of methods for evaluating regulatory and compliance systems...

BACKGROUND: Although health technology assessment (HTA) systems base their decision making process either on economic evaluations or comparative clinical benefit assessment, a central aim of recent approaches to value measurement, including value based assessment and pricing, points towards the incorporation of supplementary evidence and criteria that capture additional dimensions of value. OBJECTIVE: To study the practices, processes and policies of value-assessment for new medicines across eight European countries and the role of HTA beyond economic evaluation and clinical benefit assessment...

Aim This study aimed to explore the ability of sexual health nurses working in the South West of England, to implement new learning within existing sexual health service delivery models. Drawing on Lipsky's account of street-level bureaucracy to conceptualise policy implementation, the impact of workforce learning on the development of integrated services across this region of the United Kingdom was assessed. BACKGROUND: In order to achieve the United Nations' goal of universal access to sexual health, it is essential for reproductive and sexual health, including HIV provision, to integrate into a single service...

BACKGROUND: Fluorescence technology with indocyanine green (ICG) provides a real-time assessment of intestinal perfusion. However, a subjective evaluation of fluorescence intensity based on the surgeon's visual judgement is a major limitation. This study evaluated the quantitative assessment of ICG fluorescence imaging in determining the transection line of the proximal colon during laparoscopic colorectal surgery. METHODS: This is a retrospective analysis of a prospectively maintained database of 112 patients who underwent laparoscopic surgery for left-sided colorectal cancers...

The ability of correlation integral for automatic seizure detection using scalp EEG data has been re-examined in this paper. To facilitate the detection performance and overcome the shortcoming of correlation integral, nonlinear adaptive denoising and Kalman filter have been adopted for pre-processing and post-processing. The three-stage algorithm has achieved 84.6% sensitivity and 0.087/h false detection rate, which are comparable to many machine learning based methods, but at much lower computational cost...

Americans face inevitable trade-offs between health care affordability, accessibility, and innovation. Although numerous reforms have been proposed, universal principles to guide decision-making are lacking. Solving the challenges that confront us will be difficult, owing to intense partisan divisions and a dysfunctional political process. Nevertheless, we must engage in reasoned debate that respects deeply held differences of opinion regarding our individual and collective obligations to promote healthy living and ensure affordable access to health care...

Human babies not only are reliable triggers of tender feelings and protective tendencies, they also happen to be exceptionally fat compared to the newborns of most other species. These two facts are used to formulate a hypothesis predicting that overweight males, due to their great physical resemblance to babies, not only are perceived as cute, but also are associated with negatively evaluated traits (e.g., immaturity, lack of willpower) that are saliently inconsistent with traits required for adults. In this study, a great many physical features of adult males varying widely in weight were measured and correlated with subjective judgements...

Therapeutic decision-making for patients with multimorbidity (MM) is challenging. Clinical practice guidelines inadequately address harmful interactions and resulting therapeutic conflicts within and among diseases. A patient-specific measure of MM severity that takes account of this conflict is needed.As a proof of concept, we evaluated whether the new Multimorbidity Interaction Severity Index (MISI) could be used to reliably differentiate patients in terms of lower versus higher potential for harmful interactions...

BACKGROUND: Although surgeons must perform implantation of the cementless stem during total hip arthroplasty (THA) without complications, assessment is left to the surgeon's intuitive judgement, which could contain inter/intra-observer bias variety. We therefore asked (1) whether the sound created during the stem implantation could be evaluated objectively and (2) whether those sounds are correlate to the complication specific to the cementless stems. Our hypothesis is that the sounds produced during stem insertion could be quantified and related to the complications...

F Smyth Zahra, K Dunton
By its nature, clinical teaching involves supporting small groups of dental students at the chairside as they treat their own patients. Scaffolding their learning in this way enables observation at close quarters of the various stages of development from early novice, just commencing clinical treatment of patients, to those approaching qualification. The students' main concerns throughout are not primarily with the technical skills required, which they have already been taught in the clinical skills laboratories, but dealing with the complex realities and ambiguities of clinical practice; the 'hidden curriculum' of decision making, judgement calls, issues of communication and what it actually means to be professional...

BACKGROUND: The aim was to describe the regulatory B and T cells (Breg and Treg) and T helper 17 (Th17) lymphocytes before and under treatment with biologic drugs, and to assess their potential predictive value as biomarkers of response in rheumatoid arthritis (RA). METHODS: This was a non-randomised, single-centre, prospective study. Patients with active RA (American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) 2010) who required the initiation or switch to any biologic drug except rituximab were included...

Several neurological patient populations, including traumatic brain injury (TBI), appear to produce an abnormally 'utilitarian' pattern of judgements to moral dilemmas; they tend to make judgements that maximize the welfare of the majority, rather than deontological judgements based on the following of moral rules (e.g., do not harm others). However, this patient research has always used extreme dilemmas with highly valued moral rules (e.g., do not kill). Data from healthy participants, however, suggest that when a wider range of dilemmas are employed, involving less valued moral rules (e...

The current difficulty facing risk evaluations of Bacillus thuringiensis (Bt) crops on nontarget arthropods (NTAs) is the lack of criteria for determining what represents unacceptable risk. In this study, we investigated the biological parameters in the laboratory and field population abundance of Nilaparvata lugens (Hemiptera: Delphacidae) on two Bt rice lines and the non-Bt parent, together with 14 other conventional rice cultivars. Significant difference were found in nymphal duration and fecundity of N...

Whilst a formal statistical analysis of any experimental data is always preferable in principle, in the case of Pilling et al. (PLoS ONE 8:e77193, 2013), it is hard to see how the results of any formal analysis-including those provided by Schick et al.-could be considered reliable. Regardless of the issue of statistical analysis, there was a wealth of valuable and novel biological and chemical residue data generated under field conditions of use in Pilling et al., which when taken into consideration alongside other relevant available published data and information (i...
