Early and appropriate blood culture sampling is recommended as a standard of care for patients with suspected bloodstream infections (BSI) but is rarely taken into account when quality indicators for BSI are evaluated. To date, sampling of about 100 to 200 blood culture sets per 1,000 patient-days is recommended as the target range for blood culture rates. However, the empirical basis of this r...

The large majority of current systems for handling geospatial information are static, concentrating on a single temporal snapshot, usually the current state. Changes in the application domain are tracked in the system by performing updates and erasing information on the past. In recent years there has evolved a body of research, both in the general database community (Snodgrass 1992) and in the...

To investigate the spatial and behavioral correlates of striatal neurons during displacement movements, the rostromedial dorsal striata (AP 1.0-2.2, ML 1.5-2.0) of five rats were surgically implanted with advanceable bundles of fine wire electrodes. After recovery, the rats were deprived of water and trained in a square-walled open field in a dark room. The behavioral task required alternating ...

INTRODUCTION Patients in intensive care units (ICUs) suffer from sleep deprivation arising from nursing interventions and ambient noise. This may exacerbate confusion and ICU-related delirium. The World Health Organization (WHO) suggests that average hospital sound levels should not exceed 35 dB with a maximum of 40 dB overnight. We monitored five ICUs to check compliance with these guidelines....

A method has been developed for accurately and precisely measuring the activity of a range of plasminogen activators (PAs) used as thrombolytic agents, including streptokinase, tissue plasminogen activator (tPA) and variants, and urokinase (uPA), both single and two chain forms. Plasminogen activation is monitored in a transparent, solid fibrin matrix but uses chromogenic substrate hydrolysis, ...

introduction: increasing costs of health and treatment services has led health economics specialists and even physicians in all countries to seek new methods for controlling and reducing costs in medical and health services. the present study was aimed to estimate the costs of a cardiac care unit (ccu) in a governmental hospital in iran. methods: in order to determine the end cost, a stepwise p...

Comodulation masking release (CMR) enhances the detection of signals embedded in wideband, amplitude-modulated maskers. At least part of the CMR is attributable to across-frequency processing, however, the relative contribution of different stages in the auditory system to across-frequency processing is unknown. We have measured the responses of single units from one of the earliest stages in t...

We propose a procedure based on a latent variable model for the comparison of two partitions of different units described by the same set of variables. The null hypothesis here is that the two partitions come from the same underlying mixture model. We define a method of “projecting” partitions using a supervised classification method: once one partition is taken as a reference; the individuals ...

OBJECTIVE To characterize rheumatoid arthritis patients seen in Rheumatology Units at different health care levels. MATERIAL AND METHODS Questionnaire and clinical examination of rheumatoid arthritis patients seen as outpatients in Rheumatology Units from Primary Care, county Hospitals and Reference Hospitals. Demographic, social, labour and disease data were collected. Statistical study incl...

Software systems are subject to ever increasing complexity and in need of efficient structuring. The concept of organization as an expressive and abstract realworld reference presents a promising starting point. In the field of computer science, organizations have particularly been studied within the multi-agent systems community. However, the individual agent metaphor turns out to be of rather...
