Disease specific intelligent pre-fetch and hanging protocol for diagnostic neuroradiology workstations.

Clinical data sets for neuroradiological cases can be quite large. A typical brain tumor patient at UCLA will undergo 8-10 separate studies over a 2 year period, each study will produce 60-100 magnetic resonance (MR) images. Gathering and sorting through a patient s imaging events during the course of treatment can be both overwhelming and time consuming. The purpose of this research is to develop an intelligent pre-fetch and hanging protocol that automatically gathers the relevant prior examinations from a picture archiving, and communication systems (PACS) archive and sends the pertinent historical images to the diagnostic display station where the new examination is subsequently read out. The intelligent hanging protocol describes the type of layout and sequence for image display. We have developed a classification scheme to organize the pertinent patient information to selectively pre-fetch and intelligently present the images to review brain tumor cases for a diagnostic neuroradiology workstation.

Physicians' emotional intelligence and patient satisfaction.

BACKGROUND AND OBJECTIVES: This study investigated the relationship between patient satisfaction and physicians' scores on a test of emotional intelligence. METHODS: Faculty and resident physicians at a southern medical school completed the Bar-On Emotional Quotient Inventory (EQi). Patient subjects were recruited at the conclusion of an office visit and completed a patient satisfaction survey. Spearman rank order correlations and t tests were used to examine the relationship between global, composite, and subscale scores on the EQi and patient satisfaction. Race, gender, and resident/faculty status were compared via t tests. RESULTS: When patient satisfaction scores were used to dichotomize physicians into two groups, those with 100% satisfied patients and those with less than 100% satisfaction, only one subscale of EQi, "happiness," was related to higher satisfaction. CONCLUSIONS: Findings suggest a limited relationship between physicians'scores on a test of emotional intelligence and patient satisfaction. Implications for physician training programs are offered in light of recent focus on physician-patient communication in medical education. Application of emotional intelligence concepts to physician skills and patient attitudes needs further research that may lead to further educational opportunities.

[A comparative study on cytocompatibility of medical PVA and intelligent PVA-g-NIPAAm hydrogels].

"Intelligent" Polymers which resonse with large property changes to small physical or chemical stimuli are attracting more and more attention in the field of medical science. One trend in the area is to modify some conventional medical polymers to form intelligent biomaterials. This investigation was designed to evaluate and compare in vitro cytocompatibility of PVA hydrogel, which could be used as a kind of solid support with good biomcompatibility, and PVA-g-NIPAAm, which was produced by irradiation grafting of NIPAAm onto the said PVA hydrogel support. Cytotoxicity test was carried out with a modified Cell Relative Growth Rate test (RGR test). On the day 2, day 4 and day 7, the RGRs of the PVA hydrogel were 82%, 90% and 102% respectively while the RGRs of the PVA-g-NIPAAm were 77%, 86% and 100%. The grades of the cytotoxicity of the PVA and PVA-g-NIPAAm hydrogels were 0, so they had no cytotoxicity as judged by our tests. After 24 hours, cells in direct contact with the two kinds of samples were observed morphologically through the Olympus inverted microscope and had a normal development. The conclusion suggests that irradiation grafting is a good way to modify conventional medical polymers to produce intelligent biomaterials.

U.S. military officer participation in the Centers for Disease Control and Prevention's Epidemic Intelligence Service (1951-2001).

The Epidemic Intelligence Service (EIS) was created in 1951 to provide epidemiologists to investigate natural and intentional disease epidemics. From an initial class of 23 U.S. citizens, the program has evolved into a globally recognized, hands-on learning experience, accepting approximately 65 to 75 new officers each year. The first U.S. military epidemic intelligence service officer (EISO) was accepted into the program in 1994. Since that time, 12 such officers have completed, or have begun, EIS training. They have comprised 2.1% of all EISOs from 1994 to 2001 and 0.47% of all EISOs. This total has included nine Air Force veterinarians, one Army veterinarian, one Army physician, and one Navy physician. Each military EISO had the opportunity to lead investigations of significant public health events (e.g., Ebola, monkeypox, malaria, Nipah virus, West Nile fever, and anthrax outbreaks). All graduates from the military returned to active duty assignments in operational medical units, research institutes, or the intelligence community.

The comparability of the WRAT-R reading test and NAART as estimates of premorbid intelligence in neurologically impaired patients.

A study by Wiens, Bryan, and Crossen (1993) suggests the Wide Range Achievement Test-Revised (WRAT-R) Reading subtest and North American Adult Reading Test (NAART) are adequate predictors of Wechsler Adult Intelligence Scale-Revised (WAIS-R) IQ scores for a normal population. Although it is common practice to use reading scores to estimate premorbid IQ in clinical populations, the WRAT-R and NAART have not been compared using individuals with brain dysfunction. The current study cross-validated the Wiens et al. (1993) study using neurologically impaired populations: traumatic brain injury (n = 118), dementia (n = 37), and other neurologic impairments (n = 77). The results were generally consistent across all three groups: (a) the WRAT-R and NAART were equivalent and accurate estimates of average VIQ levels; (b) the WRAT-R and NAART were equivalent but underestimates of higher intelligence ranges; and (c) the WRAT-R is a more accurate estimate for lower VIQ ranges, although both are overestimates. This third finding is in contrast to Wiens et al.'s (1993) results that suggest the WRAT-R is an accurate estimate of lower IQ ranges for normals. It is concluded that the WRAT-R is the preferred measure of premorbid verbal intelligence for psychometric and clinical reasons.

Methodology, inference and causation: environmental lead exposure and childhood intelligence.

Kaufman's critique of the literature on the associations between lead exposure and child intelligence raises important methodological and inferential points. We address the concerns he raises regarding measuring known and unknown confounders, statistical modeling, reverse causality and quality control. Mismeasurement of potential confounders of the lead-IQ relationship, such as parenting skills, parental intelligence, maternal smoking during pregnancy, or otitis media can either strengthen or weaken the estimated association between exposure and child intelligence. Despite some variability in design and measurement, a series of comprehensive prospective investigations in varied populations, by different sets of investigators, provided consistent replication; taken together these studies point to the conclusion that lead exposure has adverse consequences for child development, and that the deficits are likely to be small in comparison to the contribution of measured social factors.

Biological versus psychometric intelligence: Halstead's (1947) distinction revisited.

This article reports an investigation into the empirical status of a little understood cognitive factor-tactile-kinesthetic ability. To this end, a variety of haptic tasks, including three subtests of the Halstead-Reitan Neuropsychological Test Battery (HRB), were administered to 108 participants, along with established markers commonly employed in contemporary psychometric investigations. The results suggest that these subtests of the HRB measure cognitive abilities conceptually equivalent to fluid intelligence. Since these tests reflect efforts to operationalize Halstead's (1947) concept of "biological intelligence," the results reported herein allow evaluation of this concept in relation to current models of human intelligence. Previous studies investigating the nature of abilities assessed by the HRB have reached contradictory conclusions. Present findings clarify the source of these anomalies.

Correlation between intelligence test scores and executive function measures.

In this study, some executive function measures (Wisconsin Card Sorting Test [WCST], verbal fluency, and Trial Making Test [TMT], Form A and Form B) were correlated with Wechsler Intelligence Scale for Children-Revised (WISC-R) scores. Fifty 13- to 16-year-old normal children were selected. It was found that verbal fluency tests correlated about 0.30 with Verbal Intelligence Quotient (IQ) and Full Scale IQ. In the WCST only Perseverative Errors negatively correlated with Verbal IQ and Full Scale IQ. Two correlations were found to be significant with regard to the TMT: TMT Form B Errors negatively correlated with WISC-R Vocabulary subtest; and TMT Form A Time negatively correlated with Performance IQ. These results support the assumption that traditional intelligence tests are not appropriately evaluating executive functions.

Leveraging intelligent agents for knowledge discovery from heterogeneous healthcare data repositories.

This paper presents a case for an intelligent agent based framework for knowledge discovery in a distributed healthcare environment comprising multiple heterogeneous healthcare data repositories. Data-mediated knowledge discovery, especially from multiple heterogeneous data resources, is a tedious process and imposes significant operational constraints on end-users. We demonstrate that autonomous, reactive and proactive intelligent agents provide an opportunity to generate end-user oriented, packaged, value-added decision-support/strategic planning services for healthcare professionals, manages and policy makers, without the need for a priori technical knowledge. Since effective healthcare is grounded in good communication, experience sharing, continuous learning and proactive actions, we use intelligent agents to implement an Agent based Data Mining Infostructure that provides a suite of healthcare-oriented decision-support/strategic planning services.

Cultural intelligence.

In an increasingly diverse business environment, managers must be able to navigate through the thicket of habits, gestures, and assumptions that define their coworkers' differences. Foreign cultures are everywhere--in other countries, certainly, but also in corporations, vocations, and regions. Interacting with individuals within them demands perceptiveness and adaptability. And the people who have those traits in abundance aren't necessarily the ones who enjoy the greatest social success in familiar settings. Cultural intelligence, or CQ, is the ability to make sense of unfamiliar contexts and then blend in. It has three components--the cognitive, the physical, and the emotional/motivational. While it shares many of the properties of emotional intelligence, CQ goes one step further by equipping a person to distinguish behaviors produced by the culture in question from behaviors that are peculiar to particular individuals and those found in all human beings. In their surveys of 2,000 managers in 60 countries, the authors found that most managers are not equally strong in all three of these areas of cultural intelligence. The authors have devised tools that show how to identify one's strengths, and they have developed training techniques to help people overcome weaknesses. They conclude that anyone reasonably alert, motivated, and poised can attain an acceptable CQ.

Wearable textile biofeedback systems: are they too intelligent for the wearer?

The Intelligent Knee Sleeve is a device capable of providing immediate audible feedback to the wearer pertaining to knee flexion angle during human movement. The Intelligent Knee Sleeve was used in a landing training program to determine whether providing subjects with this form of feedback was able to effect a change in knee flexion angle during dynamic landing tasks. Preliminary results suggest that the feedback modality is effective in correcting landing technique. However, advancements in the Intelligent Knee Sleeve design would produce a more robust system leading to more effective biofeedback for the athlete.

Building an emotionally intelligent medical practice.

This article reviews each of the five components of emotional intelligence, describes their relevance to the management of contemporary medical practices, and provides some practical steps health professionals and practice managers can take to enhance emotional intelligence. The benefits derived from such a review will necessarily vary from person to person and practice to practice, depending on the baseline from which we begin. Nevertheless, all of us can benefit from learning more about emotional intelligence.

Lies and coercion: why psychiatrists should not participate in police and intelligence interrogations.

Police interrogators routinely use deceptive techniques to obtain confessions from criminal suspects. The United States Executive Branch has attempted to justify coercive interrogation techniques in which physical or mental pain and suffering may be used during intelligence interrogations of persons labeled unlawful combatants. It may be appropriate for law enforcement, military, or intelligence personnel who are not physicians to use such techniques. However, forensic psychiatry ethical practice requires honesty, striving for objectivity, and respect for persons. Deceptive and coercive interrogation techniques violate these moral values. When a psychiatrist directly uses, works with others who use, or trains others to use deceptive or coercive techniques to obtain information in police, military, or intelligence interrogations, the psychiatrist breaches basic principles of ethics.

Hearing loss and radiotelephony intelligibility in civilian airline pilots.

Airline pilots with a mild to moderate hearing loss are regularly examined in the Netherlands National Aerospace Medical Centre. If this hearing loss exceeds the national hearing standards not only a tone-audiometric test but also routine speech-audiometry is performed. The maximal discrimination of phonetically balanced monosyllable words (20 word lists) in 16 airline pilots (32 ears) with such a hearing loss varies between 65%-100%. However, none of these pilots complains of a bad speech-intelligibility in the cockpit. This may indicate that there is a poor relation between the routine speech discrimination and the speech intelligibility in the working situation. We developed a "speech-audiometric" test (RT-test) which is completely based on the aviation jargon used in radiotelephony (RT) communications. In our group of 16 pilots the maximal discrimination in the RT-test was excellent. Even for ears with a maximal discrimination of 65%-70% in the routine speech-audiometric test the maximal RT-discrimination was 99%-100%. These pilots were all very experienced (average: 14,360 flying hours). Undoubtedly, this experience is of great importance in radiotelephony-intelligibility.

Speech intelligibility through communication headsets for general aviation.

Word discrimination was measured on eight general aviation pilots listening alternately through each of three communication headsets and an aircraft loudspeaker in the presence of light aircraft noise. Each subject listened at the speech intensity designated by him as yielding optimal intelligibility. Performance varied directly with the degree of attenuation provided by the headset. Mean intelligibility scores ranged from 73% through the loudspeaker to 92% through two of the headsets, although retesting through the loudspeaker at a higher signal level improved mean scores to 85%. Articulation functions obtained on four normally hearing listeners tested under the same conditions as the pilots revealed that, for situations when little or no attenuation was available (loudspeaker and one headset), greater signal-to-noise ratios were necessary to allow discrimination equivalent to that obtained under conditions of greater noise attenuation (two headsets). Although good intelligibility could be achieved through the loudspeaker given sufficient signal intensity (greater than 100 dB SPL) some pilots preferred lower levels even though discrimination was reduced.

The work of the Drugs Intelligence Laboratory, Home Office Forensic Science Service.

The primary purpose of the Drugs Intelligence Laboratory is to help the police identify sources of supply and manufacture of illicit drugs. This is done by providing scientific support to the Central Drugs and Illegal Immigration Intelligence Unit, a national police unit based at New Scotland Yard, London. The Laboratory provides detailed information on United Kingdom drug seizures and data obtained from a programme of comparison and characterization of seized samples. This intelligence information is then used to supplement that obtained through normal police channels in the search for illicit drug sources, manufacturers or distributors. This paper describes the techniques used for comparing and characterizing various drug preparations and outlines the type of information that can be gained from such studies.

Syllabic compression and speech intelligibility in hearing impaired listeners.

Syllabic compression has not been shown unequivocally to improve speech intelligibility in hearing-impaired listeners. This paper attempts to explain the poor results by introducing the concept of minimum overshoots. The concept was tested with a digital signal processor on hearing-impaired subjects. The results show that moderate syllabic compression may raise speech intelligibility, as long as overshoots are minimized and relatively short time constants are used. Frequency equalization also contributes to speech intelligibility.
