Vital signs monitoring system  

NASA Technical Reports Server (NTRS)

A system is disclosed for monitoring vital physiological signs. Each of the system components utilizes a single hybrid circuit with each component having high accuracy without the necessity of repeated calibration. The system also has low power requirements, provides a digital display, and is of sufficiently small size to be incorporated into a hand-carried case for portable use. Components of the system may also provide independent outputs making the component useful, of itself, for monitoring one or more vital signs. The overall system preferably includes an ECG amplifier and cardiotachometer signal conditioner unit, an impedance pneumograph and respiration rate signal conditioner unit, a heart/breath rate processor unit, a temperature monitoring unit, a selector switch, a clock unit, and an LCD driver unit and associated LCDs, with the system being capable of being expanded as needed or desired, such as, for example, by addition of a systolic/diastolic blood pressure unit.

Wearable system for vital signs monitoring.  

PubMed

A new concept in healthcare, aimed at providing continuous remote monitoring of user's vital signs, is emerging. An innovative system named WEALTHY is presented, where conducting and piezoresistive materials in the form of fiber and yarn are integrated and used as sensor and electrode elements. The simultaneous recording of vital signs allows parameter extrapolation and inter-signal elaboration that contribute to producing alert messages and synoptic patient tables. Cardiac patients in the rehabilitation phase can be continuously monitored during selected time intervals, such as during physical activity or occurrence of symptoms, to discover potential threats and generate appropriate alerts to the patient and/or to an emergency center. The core of the system sensing is a textile interface, in which the sensing components are elements of the fabric: the sensorized garment is comfortable like a common article of clothing and is made with knitting machines; furthermore, the position of the electrodes and sensors is fixed and the elasticity of the fabric allows a good fitting to the body. The system is provided with a portable electronic unit, where signals are acquired, elaborated and transmitted. A monitoring system allows extrapolation of a new physiological index and data flow coordination as well as alarm management and database creation. PMID:15718653

A non-contact vital signs monitor.  

PubMed

The expansion and contraction of the lungs and heart result in movement of the chest wall that can be detected and monitored to determine respiration and heart rate. A prototype non-contact Vital Signs Monitor (VSM) has been developed which uses very low power, high frequency Doppler radar to detect these motions. Digital signal processing (DSP) techniques, imbedded in the VSM, are used to extract heart and respiration rate information from the resultant waveform. A 10-GHz prototype VSM was developed for the Air Force in the mid-1980s using analog technology. The objective was to assess a fallen soldier's clinical condition at distances up to 100 meters before committing resources to assist that individual. An updated and improved version of the original VSM was developed in 1997. This device was designed to operate at shorter distances, use a higher frequency carrier, and provide more specific heart and respiration rate information using digital signal processing techniques. The VSM radar system is a straightforward homodyne receiver. It operates using frequency modulated continuous wave (FM-CW) transmission, which allows for very low power levels. The safe human power density exposure level at its operating frequency of 35 GHz is 10 mW/cm2. A simple approximation using uniform distribution and an antenna aperture of 2 cm by 3 cm gives a power density at the antenna face of 0.017 mW/cm2, nearly a factor of 1000 below the safe level. When the VSM's antenna is trained on the chest wall of a subject, the VSM is capable of measuring and distinguishing minute movements resulting from the mechanical activity of the heart and lungs. As the subject's chest wall moves, the exact phase of the return signal changes. To avoid the possibility of phase-related dead spots, two signals differing in phase by 90 degrees are used to demodulate the signal to baseband (DC). The two resulting "time-varying DC" signals represent the sine and cosine of a phase angle corresponding to the changing position of the target, in this case the motion of the chest wall. The current VSM operates at a frequency of 35 GHz with a corresponding wavelength of only 8.6 mm. This provides a response sensitive enough to detect the small motions caused by cardiac function. The Vital Signs Monitor has several possible application areas. The fact that it is noncontacting would make it especially attractive for monitoring patients in burn units, NICUs, or trauma centers, where attaching electrodes is either inconvenient or not feasible. Results to date indicate a strong correlation between the cardiac component of the motion signal and an electrocardiogram (ECG). With careful signal processing and analysis, it may be possible to extract clinically useful information about cardiac condition, function, or performance from the surface-motion waveform. This could provide a safe, inexpensive, and painless addition to the diagnostic and monitoring tools currently available to cardiologists. Although there are technical obstacles to overcome in filtering gross motions of the subject, the VSM offers significant advances over conventional methods of measuring heart and respiration rate.

Vital Signs in Older Patients: Age-Related Changes  

PubMed Central

Vital signs are objective measures of physiological function that are used to monitor acute and chronic disease and thus serve as a basic communication tool about patient status. The purpose of this analysis was to review age-related changes of traditional vital signs (blood pressure, pulse, respiratory rate, and temperature) with a focus on age-related: a) molecular changes; b) organ system changes; c) systemic changes; d) altered compensation to stressors. The review found that numerous physiological and pathological changes may occur with age and alter vital signs. These changes tend to reduce the ability of organ systems to adapt to physiological stressors, particularly in frail older patients. Because of the diversity of age-related physiological changes and comorbidities in an individual, single-point measurements of vital signs have less sensitivity in detecting disease processes. However, serial vital sign assessments may have increased sensitivity, especially when viewed in the context of individualized reference ranges. Vital sign change with age may be subtle because of reduced physiological ranges. However, change from an individual reference range may indicate important warning signs and thus may require additional evaluation to understand potential underlying pathological processes. As a result, individualized reference ranges may provide improved sensitivity in frail, older patients.

Gaussian process regression in vital-sign early warning systems.  

PubMed

The current standard of clinical practice for patient monitoring in most developed nations is connection of patients to vital-sign monitors, combined with frequent manual observation. In some nations, such as the UK, manual early warning score (EWS) systems have been mandated for use, in which scores are assigned to the manual observations, and care escalated if the scores exceed some pre-defined threshold. We argue that this manual system is far from ideal, and can be improved using machine learning techniques. We propose a system based on Gaussian process regression for improving the efficacy of existing EWS systems, and then demonstrate the method using manual observation of vital signs from a large-scale clinical study.

BMI: a vital sign for patients and health professionals.  

PubMed

Body mass index (BMI) is a significant indicator of health and well-being.The notion of considering BMI as a vital sign was first put forward over a decade ago; however, many health-care professionals do not routinely measure height and weight, or calculate BMI. Given the current obesity epidemic, this oversight has implications for the diagnosis and management of obesity and for appropriate healthcare delivery for obese patients. The authors propose that BMI should be considered a vital sign.They suggest that protocols be put in place to encourage health-care providers to record BMI routinely and to take action to address a BMI that is outside the normal range. Promoting the routine calculation of BMI on admission or initial assessment may encourage health-care professionals to become more aware of obesity and its impact on the patient and the health system.

Millimeter-wave radar for vital signs sensing  

NASA Astrophysics Data System (ADS)

In this paper, we will describe the development of a 228 GHz heterodyne radar system as a vital signs sensing monitor that can remotely measure respiration and heart rates from distances of 1 to 50 meters. We will discuss the design of the radar system along with several studies of its performance. The system includes the 228 GHz transmitter and heterodyne receiver that are optically coupled to the same 6 inch optical mirror that is used to illuminate the subject under study. Intermediate Frequency (IF) signal processing allows the system to track the phase of the reflected signal through I and Q detection and phase unwrapping. The system monitors the displacement in real time, allowing various studies of its performance to be made. We will review its successes by comparing the measured rates with a wireless health monitor and also describe the challenges of the system.

Vital sign sensing method based on EMD in terahertz band  

NASA Astrophysics Data System (ADS)

Non-contact respiration and heartbeat rates detection could be applied to find survivors trapped in the disaster or the remote monitoring of the respiration and heartbeat of a patient. This study presents an improved algorithm that extracts the respiration and heartbeat rates of humans by utilizing the terahertz radar, which further lessens the effects of noise, suppresses the cross-term, and enhances the detection accuracy. A human target echo model for the terahertz radar is first presented. Combining the over-sampling method, low-pass filter, and Empirical Mode Decomposition improves the signal-to-noise ratio. The smoothed pseudo Wigner-Ville distribution time-frequency technique and the centroid of the spectrogram are used to estimate the instantaneous velocity of the target's cardiopulmonary motion. The down-sampling method is adopted to prevent serious distortion. Finally, a second time-frequency analysis is applied to the centroid curve to extract the respiration and heartbeat rates of the individual. Simulation results show that compared with the previously presented vital sign sensing method, the improved algorithm enhances the signal-to-noise ratio to 1 dB with a detection accuracy of 80%. The improved algorithm is an effective approach for the detection of respiration and heartbeat signal in a complicated environment.

Validation of vital signs recorded via a new telecare system.  

PubMed

A telecare system (Medic4All) has been developed that relies on a wireless wristwatch-like sensor to measure the pulse wave from the radial artery. From this, the heart rate and respiration rate are derived. The system's performance was examined by comparing the results obtained from the pulse wave signal with those obtained from conventional electrocardiographic and spirometer devices. A total of 144 patients participated in the study; their mean (SD) age was 43 (18) years. There were 44 cardiac patients in group 1 and 100 healthy patients, who were studied in their homes, in group 2. There was a significant correlation between the heart rates measured by the two monitoring methods. A 'difference versus average' analysis showed that the error distribution had a mean (SD) value of -0.1 (3.3) beats/min. Similarly, the respiration rates measured by the two techniques were significantly correlated. The error distribution had a mean (SD) value of 0.1 (1.9) respirations/min. The present study suggests that the wrist-worn sensor represents a promising tool for online detection and monitoring of vital signs in the home. PMID:14680516

Validating Emergency Department Vital Signs Using a Data Quality Engine for Data Warehouse  

PubMed Central

Background : Vital signs in our emergency department information system were entered into free-text fields for heart rate, respiratory rate, blood pressure, temperature and oxygen saturation. Objective : We sought to convert these text entries into a more useful form, for research and QA purposes, upon entry into a data warehouse. Methods : We derived a series of rules and assigned quality scores to the transformed values, conforming to physiologic parameters for vital signs across the age range and spectrum of illness seen in the emergency department. Results : Validating these entries revealed that 98% of free-text data had perfect quality scores, conforming to established vital sign parameters. Average vital signs varied as expected by age. Degradations in quality scores were most commonly attributed logging temperature in Fahrenheit instead of Celsius; vital signs with this error could still be transformed for use. Errors occurred more frequently during periods of high triage, though error rates did not correlate with triage volume. Conclusions : In developing a method for importing free-text vital sign data from our emergency department information system, we now have a data warehouse with a broad array of quality-checked vital signs, permitting analysis and correlation with demographics and outcomes.

Monitors Track Vital Signs for Fitness and Safety  

NASA Technical Reports Server (NTRS)

Have you ever felt nauseous reading a book in the back seat of a car? Or woken from a deep sleep feeling disoriented, unsure which way is up? Momentary mixups like these happen when the sensory systems that track the body's orientation in space become confused. (In the case of the backseat bookworm, the conflict arises when the reader s inner ear, part of the body s vestibular system, senses the car s motion while her eyes are fixed on the stationary pages of the book.) Conditions like motion sickness are common on Earth, but they also present a significant challenge to astronauts in space. Human sensory systems use the pull of gravity to help determine orientation. In the microgravity environment onboard the International Space Station, for example, the body experiences a period of confusion before it adapts to the new circumstances. (In space, even the body s proprioceptive system, which tells the brain where the arms and legs are oriented without the need for visual confirmation, goes haywire, meaning astronauts sometimes lose track of where their limbs are when they are not moving them.) This Space Adaptation Syndrome affects a majority of astronauts, even experienced ones, causing everything from mild disorientation to nausea to severe vomiting. "It can be quite debilitating," says William Toscano, a research scientist in NASA s Ames Research Center Psychophysiology Laboratory, part of the Center s Human Systems Integration Division. "When this happens, as you can imagine, work proficiency declines considerably." Since astronauts cannot afford to be distracted or incapacitated during critical missions, NASA has explored various means for preventing and countering motion sickness in space, including a range of drug treatments. Many effective motion sickness drugs, however, cause undesirable side effects, such as drowsiness. Toscano and his NASA colleague, Patricia Cowings, have developed a different approach: Utilizing biofeedback training methods, the pair can teach astronauts, military pilots, and others susceptible to motion sickness to self-regulate their own physiological responses and suppress the unpleasant symptoms. This NASA-patented method invented by Cowings is called the Autogenic Feedback Training Exercise (ATFE), and several studies have demonstrated its promise

Vital Signs Investigation in Subjects Undergoing MR Imaging at 8T  

PubMed Central

PURPOSE This study investigates physiologic vital signs in subjects, with and without cerebral pathologies, undergoing ultra-high-field (UHF) 8T MR imaging. METHODS AND SUBJECTS Eighteen normal subjects and 74 subjects with cerebral pathology consented for 8T UHF MR imaging. T2*-weighted gradient-echo and T2-weighted rapid acquisition relaxation excitement sequences were used. Physiologic vital signs measured included systolic blood pressure, diastolic blood pressure, mean arterial pressure, electrocardiogram, heart rate (HR), respiratory rate (RR), and pulse oxygen saturation rate. They were collected before, during, and after imaging. Mean vital sign values at different stages were calculated and compared. Subjects were interviewed after imaging. RESULTS No adverse vital sign change was detected. Statistically significant changes after imaging included a HR decrease from 65.2 beats per minute (bpm) to 60.3 bpm (P = .001, paired Student t test) in the normal group and a RR increase from 14.5 respirations per minute (rpm) to 15.1 rpm (P = .001, paired Student t test) in the patient group. Transient vertigo sensation was reported by 27% of normal subjects and 11% of subjects with cerebral pathologies. One normal subject and one subject with cerebral pathology reported an episode of nausea and vomiting. CONCLUSION The current neurologic human MR imaging procedure at 8T UHF has no serious adverse effects on major physiologic vital signs in either normal subjects or patients. Transient vertigo, nausea, and vomiting were identified as potential risks.

BACKGROUND: Medical operation is an anxious factor that causes physiological reactions in body which consequently increases respiratory rate, heart rate and blood pressure. The aim of this study is assessing the effect of reflexotherapy on vital signs of patients before coronary artery bypass surgery in Shahid Chamran hospital of Isfahan. METHODS: Fifty volunteer patients candidated for coronary artery bypass surgery were enrolled in this clinical trial. They were divided in two (control and treatment) groups. Vital signs were measured pre and post 30 minutes reflexotherapy in treatment group. Vital signs were also measured in patients in control group at the same condition of the treatment group, but reflexotherapy was not performed. RESULTS: The mean differences of vital signs was not significant in control and treatment groups at the baseline. But post reflexotherapy intervention, systolic and diastolic blood pressure lowered significantly in the treatment group in comparison with control group (p < 0.05). No significant changes were observed for other vital sign. CONCLUSIONS: The findings of the study shows that reflexotherapy is a safe, effective, cheep nursing intervention in reducing systolic and diastolic blood pressure of patients before coronary artery bypass surgery.

Enhancing patient safety through electronic medical record documentation of vital signs.  

PubMed

As technology becomes more sophisticated in healthcare, there is increasing need to measure its impact on key quality indicators, such as error reduction, patient safety, and cost-benefit ratios. When a product is designed to decrease medical errors, the baseline error rate must be determined before implementation to accurately measure the impact. Given the opportunity to adopt a technology that would eliminate the need to manually document vital signs, a large Florida hospital decided to measure the current process and error rate of vital signs documentation. University Community Hospital in Tampa, Fla., designed a two-phase study to evaluate this process. Phase I of the study evaluated errors in the electronic medical record and traditional manual documentation. The results demonstrate that use of an EMR can reduce vital sign documentation errors by more than half compared with traditional manual documentation in paper charts. Researchers found the error rate for electronic vital signs documentation to be less than 5 percent, compared with the paper chart error rate of 10 percent. PMID:17091789

CONCLUSIONS: The findings of the study show that reflexotherapy is a safe, effective, cheep nursing intervention in reducing systolic and diastolic blood pressure of patients before coronary artery bypass surgery.

When and how do GPs record vital signs in children with acute infections? A cross-sectional study  

PubMed Central

Background NICE recommendations and evidence from ambulatory settings promotes the use of vital signs in identifying serious infections in children. This appears to differ from usual clinical practice where GPs report measuring vital signs infrequently. Aim To identify frequency of vital sign documentation by GPs, in the assessment of children with acute infections in primary care. Design and setting Observational study in 15 general practice surgeries in Oxfordshire and Somerset, UK. Method A standardised proforma was used to extract consultation details including documentation of numerical vital signs, and words or phrases used by the GP in assessing vital signs, for 850 children aged 1 month to 16 years presenting with acute infection. Results Of the children presenting with acute infections 31.6% had one or more numerical vital signs recorded (269, 31.6%), however GP recording rate improved if free text proxies were also considered: at least one vital sign was then recorded in over half (54.1%) of children. In those with recorded numerical values for vital signs, the most frequent was temperature (210, 24.7%), followed by heart rate (62, 7.3%), respiratory rate (58, 6.8%), and capillary refill time (36, 4.2%). Words or phrases for vital signs were documented infrequently (temperature 17.6%, respiratory rate 14.6%, capillary refill time 12.5%, and heart rate 0.5%), Text relating to global assessment was documented in 313/850 (36.8%) of consultations. Conclusion GPs record vital signs using words and phrases as well as numerical methods, although overall documentation of vital signs is infrequent in children presenting with acute infections.

[Design of mobile vital-signs monitoring system for the elderly in nursing home].  

PubMed

This paper proposed a mobile vital-signs monitoring system based on ZigBee localization and wireless transmission technology for the elderly in nursing home. The system can monitor the vital-signs (pulse, ECG and blood oxygen), localize human body and warn in emergency. The validity and accuracy of this system were testified by the experiments of mobile acquisition and storage of pulse. In these experiments, the measurement of pulse ranged from 50 to 170 time a minute, the mean error of which was less than 3%. The mean error of localizing was less than 4 m. And the data transmission rate was 250 kbps. The system, which effectively conducts the real-time monitoring of the health and safety situation for the elderly, has a great significance for protecting the elderly's life safety. PMID:24941773

Reservoir vital signs monitoring, 1991: Physical and chemical characteristics of water and sediment  

SciTech Connect

In the second year of TVA`s Reservoir Vital signs Monitoring program, physical/chemical measurements of water and sediment were made on fourteen TVA reservoirs (the nine mainstem Tennessee river reservoirs - Kentucky through Fort Loudoun and five tributary reservoirs - Cherokee, Douglas, Norris, Melton Hill and Tellico). In addition in 1991, limited water quality monitoring was initiated on ten tributary storage impoundments. The objective of the Vital Signs monitoring program is to assess the health or integrity of these aquatic ecosystems. Physical/chemical data collected in 1991 showed the water quality of the majority of TVA`s reservoirs to be very good, but pointed out areas for improvement and further investigation.

Embedded validity indicators on CNS vital signs in youth with neurological diagnoses.  

PubMed

Computerized screening measures can provide valuable information on cognition. However, determining the validity of obtained data is critical for interpretation. The purpose of this study was to examine the embedded validity indicators on the CNS Vital Signs battery in a sample of youth with neurological diagnoses. The sample included 275 children and adolescents (mean = 13.9, SD = 3.0) with neurological disorders. Six out of seven subtests and six of the nine domain scores on CNS Vital Signs had fewer than 5% of the sample flagged as invalid on the embedded indicators. However, the Shifting Attention Test and its derived domain scores had higher rates of being flagged. Patients with one or more flagged scores (18% of sample) were younger and had lower intellectual abilities, psychomotor speed, verbal memory, and performance on other validity tests. Compared to stand-alone validity tests, CNS Vital Signs embedded validity indicators had low sensitivity. More research is needed with the embedded indicators in youth. PMID:25034266

Vital sign abnormalities, rapid response, and adverse outcomes in hospitalized patients.  

PubMed

Rapid response activation (RRA), triggered chiefly by surpassing threshold vital sign abnormalities (TVSAs), is designed to intervene at the earliest point in a patient's deteriorating course. The authors aimed to quantify the incidence of TVSA among patients hospitalized on acute care units in a hospital that uses rapid response. During the course of 6 months, the authors compared adverse events (mortality, unexpected intensive care unit [ICU] transfers, and cardiopulmonary arrest) and TVSA among patients who triggered an RRA, patients with TVSAs and no RRA, and all other patients. At least 1 TVSA was recorded in 31.9% of stays and 12.2% of patient-days. RRA patients were more likely (22.5%) than other TVSA patients (7.9%) and other patients (1.8%) to have an adverse event (P < .01). Incidence varied by vital sign. During the investigation, only 2.5% of TVSA opportunities triggered an RRA. As systems engage electronic workflows, automatically triggering RRAs based solely on TVSAs could place a tremendous burden on systems. PMID:22378957

A non-contact vital sign monitoring system for ambulances using dual-frequency microwave radars.  

PubMed

We developed a novel non-contact monitoring system to measure the vital signs of casualties inside a moving ambulance. This system was designed to prevent exposure of patients to infectious organisms under biochemical hazard conditions. The system consists of two microwave radars: a 10-GHz respiratory-monitoring radar is positioned 20 cm away from the surface of the isolator. The 24-GHz cardiac-monitoring radar is positioned below the stretcher underneath the isolator. The subject (22.13 +/- 0.99 years) was placed inside the isolator on a stretcher in the simulated ambulance. While the ambulance was in motion at a speed of approximately 10 km/h, the heart rates determined by the cardiac-monitoring radar correlated significantly with those measured by ECG (r = 0.69, p < 0.01), and the respiratory rates derived from the respiratory-monitoring radar correlated with those measured by the respiration curves (r = 0.97, p < 0.0001). The proposed system appears promising for future on-ambulance monitoring of the vital sign of casualties exposed to toxins. PMID:18946695

Noncontact vital sign monitoring system for isolation unit (casualty care system).  

PubMed

For measuring the vital signs of casualties inside an isolation unit, we developed a noncontact vital sign monitoring system using a microwave radar. The system was tested on eight healthy volunteers ranging in age from 30 to 48 years. The heart and respiratory rates derived by the microwave radar correlated with the heart and respiratory rates determined by electrocardiogram and respiratory sensor (r = 0.98, p < 0.0001 for heart rate; r = 0.84, p < 0.01 for respiratory rate). The exhaled CO and CO2, as a measure of trauma injury, were measured using an exhaled gas analyzer. The CO and CO2 concentrations were found to average 3.8 +/- 4.3 ppm and 2.9 +/- 0.4%, respectively. The expired air temperature and body temperature, as indicators of hemorrhagic hypothermia, averaged 31.8 +/- 1.7 degrees C and 36.2 +/- 0.4 degrees C, respectively. The results show that our system is promising for future prehospital application in determining casualty conditions for fluid infusions by the Casualty Care System intravenous lines. PMID:16895131

Reservoir monitoring: 1990 summary of vital signs and use impairment monitoring on Tennessee Valley Reservoirs  

SciTech Connect

The Tennessee Valley Authority (TVA) initiated a Reservoir Monitoring Program on 12 TVA reservoirs (the nine main stream Tennessee river reservoirs -- Kentucky through Fort Loudoun and three major tributary storage reservoirs -- Cherokee, Douglas, and Norris) in autumn 1989. The objective of the Reservoir Monitoring Program is to provide basic information on the health'' or integrity of the aquatic ecosystem in each TVA reservoir ( Vital Signs'') and to provide screening level information for describing how well each reservoir meets the swimmable and fishable goals of the Clean Water Act (Use Impairments). This is the first time in the history of the agency that a commitment to a long-term, systematic sampling of major TVA reservoirs has been made. The basis of the Vital Signs Monitoring is examination of appropriate physical, chemical, and biological indicators in three areas of each reservoir. These three areas are the forebay immediately upstream of the dam; the transition zone (the mid-reservoir region where the water changes from free flowing to more quiescent, impounded water); and the inflow or headwater region of the reservoir. The Use Impairments monitoring provides screening level information on the suitability of selected areas within TVA reservoirs for water contact activities (swimmable) and suitability of fish from TVA reservoirs for human consumption (fishable).

A data protection scheme for a remote vital signs monitoring healthcare service.  

PubMed

Personal and medical data processed by Healthcare Information Systems must be protected against unauthorized access, modification and withholding. Security measures should be selected to provide the required level of protection in a cost-efficient manner. This is only feasible if specific characteristics of the information system are examined on a basis of a risk analysis methodology. This paper presents the results of a risk analysis, based on the CRAMM methodology, for a healthcare organization offering a patient home-monitoring service through the transmission of vital signs, focusing on the identified security needs and the proposed countermeasures. The architectural and functional models of this service were utilized for identifying and valuating the system assets, the associated threats and vulnerabilities, as well as for assessing the impact on the patients and on the service provider, should the security of any of these assets is affected. A set of adequate organizational, administrative and technical countermeasures is described for the remote vital signs monitoring service, thus providing the healthcare organization with a data protection framework that can be utilized for the development of its own security plan.

Safe patient transfer system with monitoring of location and vital signs.  

PubMed

In recent years, ubiquitous computing technologies have been applied in the field of medicine. Especially radio frequency identification (RFID) and small sensor networks could provide information about medical practices and patient status in order to prevent malpractices and improve the quality of medical care. As an example of this application, we developed a new system, named "a smart stretcher," which continuously monitors the patient's vital signs and detects apnea during transfer within a hospital. This system consists of a small air-mat type pressure sensor measuring both heart rate and respiration rate and a wireless network transmitting these vital data as well as patient ID to an alerting system to notify hospital staff of patient emergencies. Results of experiments in a clinical setting indicated that the system was reliable in continuous respiration monitoring and detection of apnea during patient transfer on the stretcher; however, detection of heartbeat rate was practically difficult because of the motion noises. Moreover patient ID and location were also correctly detected in real time. These results suggested the feasibility of our system for real clinical use. PMID:19845148

Development of a baby friendly non-contact method for measuring vital signs: First results of clinical measurements in an open incubator at a neonatal intensive care unit  

NASA Astrophysics Data System (ADS)

For infants and neonates in an incubator vital signs, such as heart rate, breathing, skin temperature and blood oxygen saturation are measured by sensors and electrodes sticking to the skin. This can damage the vulnerable skin of neonates and cause infections. In addition, the wires interfere with the care and hinder the parents in holding and touching the baby. These problems initiated the search for baby friendly 'non-contact' measurement of vital signs. Using a sensitive color video camera and specially developed software, the heart rate was derived from subtle repetitive color changes. Potentially also respiration and oxygen saturation could be obtained. A thermal camera was used to monitor the temperature distribution of the whole body and detect small temperature variations around the nose revealing the respiration rate. After testing in the laboratory, seven babies were monitored (with parental consent) in the neonatal intensive care unit (NICU) simultaneously with the regular monitoring equipment. From the color video recordings accurate heart rates could be derived and the thermal images provided accurate respiration rates. To correct for the movements of the baby, tracking software could be applied. At present, the image processing was performed off-line. Using narrow band light sources also non-contact blood oxygen saturation could be measured. Non-contact monitoring of vital signs has proven to be feasible and can be developed into a real time system. Besides the application on the NICU non-contact vital function monitoring has large potential for other patient groups.

Health technology assessment review: Remote monitoring of vital signs - current status and future challenges  

PubMed Central

Recent developments in communications technologies and associated computing and digital electronics now permit patient data, including routine vital signs, to be surveyed at a distance. Remote monitoring, or telemonitoring, can be regarded as a subdivision of telemedicine - the use of electronic and telecommunications technologies to provide and support health care when distance separates the participants. Depending on environment and purpose, the patient and the carer/system surveying, analysing or interpreting the data could be separated by as little as a few feet or be on different continents. Most telemonitoring systems will incorporate five components: data acquisition using an appropriate sensor; transmission of data from patient to clinician; integration of data with other data describing the state of the patient; synthesis of an appropriate action, or response or escalation in the care of the patient, and associated decision support; and storage of data. Telemonitoring is currently being used in community-based healthcare, at the scene of medical emergencies, by ambulance services and in hospitals. Current challenges in telemonitoring include: the lack of a full range of appropriate sensors, the bulk weight and size of the whole system or its components, battery life, available bandwidth, network coverage, and the costs of data transmission via public networks. Telemonitoring also has the ability to produce a mass of data - but this requires interpretation to be of clinical use and much necessary research work remains to be done.

The physical/chemical water quality data collected in 1990 showed the water quality of these reservoirs to be very good. However, hypolimnetic anoxia during the summer months in Watts bars, Douglas, and Cherokee reservoir continues to be a concern. High concentrations of nutrients were measured in the transition zones of Cherokee and Douglas reservoirs, resulting in highly productive and eutrophic conditions in the transition zones of these reservoirs. Fecal coliform organisms were frequently detected in the forebay area of Guntersville reservoir, and higher than expected ammonia nitrogen concentrations were found at the transition zone of Wheeler reservoir. Elevated concentrations of mercury were found in Pickwick and Watts bar reservoir sediment, and high lead concentrations were found in a sediment sample collected from Guntersville reservoir. A TVA Reservoir Water Quality Index (RWQI) was developed and used to summarize water quality conditions on a scale from 0 (worst) to 100 (best).

BACKGROUND: Currently healthy heart word considered to be the objective of community health applications in many countries of the world because cardiovascular diseases are the most important factor in mortality of humans, worldwide. Coronary artery bypass graft surgery is one of the most common surgery procedures for these patients. The purpose of this study is to assess the impact of therapeutic touch on medical vital signs of patients before coronary artery bypass graft surgery. METHODS: The present study is a clinical trial with 44 samples that were selected by easy sampling method and based on two separate lists of random numbers for both men and women; they were divided into two groups. In the therapeutic touch group, intervention therapy was applied on patents for 20 minutes. Data was analyzed using descriptive and inferential statistics. RESULTS: Test results showed that there was a significant difference between the mean pulse rate before and after intervention in both groups (p < 0.001). Results also showed that there was a significant difference between the average number of breathing before and after intervention in both groups (p < 0.001). CONCLUSIONS: Considering the effects of therapeutic touch therapy as a safe and effective intervention on the patients which were revealed in this study, this technique can be used as a simple, cheap and applicable technique in all health care centers to help these patients.

Ontology-driven monitoring of patient's vital signs enabling personalized medical detection and alert.  

PubMed

A major challenge related to caring for patients with chronic conditions is the early detection of exacerbations of the disease. Medical personnel should be contacted immediately in order to intervene in time before an acute state is reached, ensuring patient safety. This paper proposes an approach to an ambient intelligence (AmI) framework supporting real-time remote monitoring of patients diagnosed with congestive heart failure (CHF). Its novelty is the integration of: (i) personalized monitoring of the patients health status and risk stage; (ii) intelligent alerting of the dedicated physician through the construction of medical workflows on-the-fly; and (iii) dynamic adaptation of the vital signs' monitoring environment on any available device or smart phone located in close proximity to the physician depending on new medical measurements, additional disease specifications or the failure of the infrastructure. The intelligence lies in the adoption of semantics providing for a personalized and automated emergency alerting that smoothly interacts with the physician, regardless of his location, ensuring timely intervention during an emergency. It is evaluated on a medical emergency scenario, where in the case of exceeded patient thresholds, medical personnel are localized and contacted, presenting ad hoc information on the patient's condition on the most suited device within the physician's reach.

Validity and Reliability of the Japanese Version of the Newest Vital Sign: A Preliminary Study  

PubMed Central

Health literacy (HL) refers to the ability to obtain, process, and understand basic health information and services, and is thus needed to make appropriate health decisions. The Newest Vital Sign (NVS) is comprised of 6 questions about an ice cream nutrition label and assesses HL numeracy skills. We developed a Japanese version of the NVS (NVS-J) and evaluated the validity and reliability of the NVS-J in patients with chronic pain. The translation of the original NVS into Japanese was achieved as per the published guidelines. An observational study was subsequently performed to evaluate the validity and reliability of the NVS-J in 43 Japanese patients suffering from chronic pain. Factor analysis with promax rotation, using the Kaiser criterion (eigenvalues ?1.0), and a scree plot revealed that the main component of the NVS-J consists of three determinative factors, and each factor consists of two NVS-J items. The criterion-related validity of the total NVS-J score was significantly correlated with the total score of Ishikawa et al.'s self-rated HL Questionnaire, the clinical global assessment of comprehensive HL level, cognitive function, and the Brinkman index. In addition, Cronbach's coefficient for the total score of the NVS-J was adequate (alpha?=?0.72). This study demonstrated that the NVS-J has good validity and reliability. Further, the NVS-J consists of three determinative factors: “basic numeracy ability,” “complex numeracy ability,” and “serious-minded ability.” These three HL abilities comprise a 3-step hierarchical structure. Adequate HL should be promoted in chronic pain patients to enable coping, improve functioning, and increase activities of daily living (ADLs) and quality of life (QOL).

The effect of expiratory rib cage compression before endotracheal suctioning on the vital signs in patients under mechanical ventilation  

PubMed Central

Background: In patients undergoing mechanical ventilation, mucus production and secretion is high as a result of the endotracheal tube. Because endotracheal suction in these patients is essential, chest physiotherapy techniques such as expiratory rib cage compression before endotracheal suctioning can be used as a means to facilitate mobilizing and removing airway secretion and improving alveolar ventilation. As one of the complications of mechanical ventilation and endotracheal suctioning is decrease of cardiac output, this study was carried out to determine the effect of expiratory rib cage compression before endotracheal suctioning on the vital signs in patients under mechanical ventilation. Materials and Methods: This study was a randomized clinical trial with a crossover design. The study subjects included 50 mechanically ventilated patients, hospitalized in intensive care wards of Valiasr and Mousavi hospitals in Zanjan, Iran. Subjects were selected by consecutive sampling and randomly allocated to groups 1 and 2. The patients received endotracheal suctioning with or without rib cage compression, with a minimum of 3 h interval between the two interventions. Expiratory rib cage compression was performed for 5 min before endotracheal suctioning. Vital signs were measured 5 min before and 15 and 25 min after endotracheal suctioning. Data were recorded on a data recording sheet. Data were analyzed using paired t-tests. Results: There were statistically significant differences in the means of vital signs measured 5 min before with 15 and 25 min after endotracheal suctioning with rib cage compression (P < 0. 01). There was no significant difference in the means of diastolic pressure measured 25 min after with baseline in this stage). But on the reverse mode, there was a significant difference between the means of pulse and respiratory rate 15 min after endotracheal suctioning and the baseline values (P < 0.002). This effect continued up to 25 min after endotracheal suctioning just for respiratory rate (P = 0.016). Moreover, there were statistically significant differences in the means of vital signs measured 5 min before and 15 min after endotracheal suctioning between the two methods (P ? 0001). Conclusions: Findings showed that expiratory rib cage compression before endotracheal suctioning improves the vital signs to normal range in patients under mechanical ventilation. More studies are suggested on performing expiratory rib cage compression before endotracheal suctioning in patients undergoing mechanical ventilation.

Accurate and continuous non-contact vital signs monitoring using phased array antennas in a clutter-free anechoic chamber.  

PubMed

Continuous and accurate monitoring of human vital signs is an important part of the healthcare industry, as it is the basic means by which the clinicians can determine the instantaneous status of their patients. Doppler-based noncontact vital signs (NCVS) sensor systems can monitor the heart and respiration rates without touching the patient, but it has been observed that that the accuracy of these NCVS sensors can be diminished by reflections from background clutters in the measurement environment, and that high directivity antennas can increase the sensing accuracy. Therefore, this work explores a NCVS sensor with continuous data taken inside an anechoic chamber where the background cluttering is negligible. In addition, a high directivity custom-made beam-steerable phased array antenna system is used to improve the performance and functionality of the 2.4GHz NCVS sensor we have built. We believe this work is the 1st systematic study using Doppler-based phased array systems for NCVS sensing performed in a clutter-free anechoic chamber. PMID:24110324

An effective low-complexity multi-vital-signs compression technique for embedded-link e-home healthcare.  

PubMed

Transplanting the existing e-home healthcare system to source-limited embedded-link device for home-use health monitoring, intelligent medical diagnosis and wireless transmission is attractive. Yet, constrains of portable storage, computing and transmission promote the need of data compression for such applications. Existing compression techniques are mostly desktop-computer-based and computation-consuming, making them unsuitable for mobile device. To tackle such a bottleneck problem, this paper addresses an effective low-complexity multi-vital-signs compression technique based on orthogonal polynomial decomposition (OPD) algorithm using Hermite functions. The technique is proposed and operated on the designated healthcare system with optimized parameters. Validated and tested with cardiovascular disease (CVD) diagnosis based on sphygmogram both experimentally and clinically, the proposed technique achieves comparable good performance with distortion less than 2% and compression ratio up to 6, and preserves significant pathological features of multi-vital-signs for clinical diagnosis. The proposed technique is highly robust even for freaky and pathological signals. In addition, the compressed results reflecting morphological features can be directly adapted to the subsequent medical analysis without further decompression. PMID:24109903

Non-contact video-based vital sign monitoring using ambient light and auto-regressive models.  

PubMed

Remote sensing of the reflectance photoplethysmogram using a video camera typically positioned 1 m away from the patient's face is a promising method for monitoring the vital signs of patients without attaching any electrodes or sensors to them. Most of the papers in the literature on non-contact vital sign monitoring report results on human volunteers in controlled environments. We have been able to obtain estimates of heart rate and respiratory rate and preliminary results on changes in oxygen saturation from double-monitored patients undergoing haemodialysis in the Oxford Kidney Unit. To achieve this, we have devised a novel method of cancelling out aliased frequency components caused by artificial light flicker, using auto-regressive (AR) modelling and pole cancellation. Secondly, we have been able to construct accurate maps of the spatial distribution of heart rate and respiratory rate information from the coefficients of the AR model. In stable sections with minimal patient motion, the mean absolute error between the camera-derived estimate of heart rate and the reference value from a pulse oximeter is similar to the mean absolute error between two pulse oximeter measurements at different sites (finger and earlobe). The activities of daily living affect the respiratory rate, but the camera-derived estimates of this parameter are at least as accurate as those derived from a thoracic expansion sensor (chest belt). During a period of obstructive sleep apnoea, we tracked changes in oxygen saturation using the ratio of normalized reflectance changes in two colour channels (red and blue), but this required calibration against the reference data from a pulse oximeter.

Frequency of Vital Signs Monitoring and its Association with Mortality among Adults with Severe Sepsis Admitted to a General Medical Ward in Uganda  

PubMed Central

Introduction Optimal vital signs monitoring of patients with severe sepsis in resource-limited settings may improve outcomes. The objective of this study was to determine the frequency of vital signs monitoring of patients with severe sepsis and its association with mortality in a regional referral hospital in Uganda. Methods We reviewed medical records of patients admitted to Mbarara Regional Referral Hospital in Southwestern Uganda with severe sepsis defined by the presence of infection plus ?2 of the systemic inflammatory response syndrome criteria, and ?1 organ dysfunction (altered mental state, hypotension, jaundice, or thrombocytopenia). We recorded frequency of vital signs monitoring in addition to socio-demographic, clinical, and outcome data. We analyzed the data using logistic regression. Results We identified 202 patients with severe sepsis. The median age was 35 years (IQR, 25–47) and 98 (48%) were female. HIV infection and anemia was present in 115 (57%) and 83 (41%) patients respectively. There were 67 (33%) in-hospital deaths. The median monitoring frequency per day was 1.1 (IQR 0.9–1.5) for blood pressure, 1.0 (IQR, 0.8–1.3) for temperature and pulse, and 0.5 (IQR, 0.3–1.0) for respiratory rate. The frequency of vital signs monitoring decreased during the course of hospitalization. Patients who died had a higher frequency of vital signs monitoring (p<0.05). The admission respiratory rate was associated with both frequency of monitoring (coefficient of linear regression 0.6, 95% CI 0.5–0.8, p<0.001) and mortality (AOR 2.5, 95% CI 1.3–5.3, p?=?0.01). Other predictors of mortality included severity of illness, HIV infection, and anemia (p<0.05). Conclusions More research is needed to determine the optimal frequency of vital signs monitoring for severely septic patients in resource-limited settings such as Uganda.

Microwave stethoscope: development and benchmarking of a vital signs sensor using computer-controlled phantoms and human studies.  

PubMed

This paper describes a new microwave-based method and associated measurement system for monitoring multiple vital signs (VS) as well as the changes in lung water content. The measurement procedure utilizes a single microwave sensor for reflection coefficient measurements, hence the name "microwave stethoscope (MiSt)," as opposed to the two-sensor transmission method previously proposed by the authors. To compensate for the reduced sensitivity due to reflection coefficient measurements, an improved microwave sensor design with enhanced matching to the skin and broadband operation, as well as an advanced digital signal processing algorithm are used in developing the MiSt. Results from phantom experiments and human clinical trials are described. The results clearly demonstrate that MiSt provides reliable monitoring of multiple VS such as the respiration rate, heart rate, and the changes in lung water content through a single microwave measurement. In addition, information such as heart waveforms that correlates well with electrocardiogram is observed from these microwave measurements. Details of the broadband sensor design, experimental procedure, DSP algorithms used for VS extraction, and obtained results are presented and discussed. PMID:23358946

Utility of vital signs, heart rate variability and complexity, and machine learning for identifying the need for lifesaving interventions in trauma patients.  

PubMed

To date, no studies have attempted to utilize data from a combination of vital signs, heart rate variability and complexity (HRV, HRC), as well as machine learning (ML), for identifying the need for lifesaving interventions (LSIs) in trauma patients. The objectives of this study were to examine the utility of the above for identifying LSI needs and compare different LSI-associated models, with the hypothesis that an ML model would be superior in performance over multivariate logistic regression models. One hundred four patients transported from the injury scene via helicopter were selected for the study. A wireless vital signs monitor was attached to the patient's arm and used to capture physiologic data, including HRV and HRC. The power of vital sign measurements, HRV, HRC, and Glasgow Coma Scale score (GCS) to identify patients requiring LSIs was estimated using multivariate logistic regression and ML. Receiver operating characteristic (ROC) curves were also obtained. Thirty-two patients underwent 75 LSIs. After logistic regression, ROC curves demonstrated better identification for LSIs using heart rate (HR) and HRC (area under the curve [AUC] of 0.81) than using HR alone (AUC of 0.73). Likewise, ROC curves demonstrated better identification for LSIs using GCS and HRC (AUC of 0.94) than using GCS and HR (AUC of 0.92). Importantly, ROC curves demonstrated that an ML model using HR, GCS, and HRC (AUC of 0.99) had superior performance over multivariate logistic regression models for identifying the need for LSIs in trauma patients. Development of computer decision support systems should utilize vital signs, HRC, and ML in order to achieve more accurate diagnostic capabilities, such as identification of needs for LSIs in trauma patients.

[Training of pharmacists in the assessment of vital signs using human subjects for the purpose of better pharmacist-patient communication].  

PubMed

Since 2005, the Japanese pharmacy education program has changed to a six year-system from a four year-system with the aim to help students obtain a higher level of clinical knowledge and skill regarding humanity and morality. Under the new pharmacy education system, the correct assessment of vital signs is observed in pharmacy practice so that pharmacists can sell "over the counter drugs (OTC)" safely. From this point of view, we started a pharmacy practice that recognizes a series of vital signs, i.e., blood pulse, blood pressure, respiratory sound, and electrocardiogram, using a physical figure subjecting to 4th-year students (n=142) . After the practice, a questionnaire was conducted in order to assess the satisfaction of the practice. The results suggested that students could successfully learn physical assessment by using physical figures (ratios more than grade 4: 60%). Students could also evaluate the necessity of physical assessment (ratios more than grade 4: 70%), suggesting the practice of using physical figures was accepted by most students. PMID:22382846

Enhancing nursing students' skills in vital signs assessment by using multimedia computer-assisted learning with integrated content of anatomy and physiology.  

PubMed

Due to constraints of increasing number of nursing students and a disproportionate shortfall of faculty members in nursing schools, it was necessary to supplement traditional lecture or lecture-demonstration with on-line multimedia materials and/or multimedia compact discs for enhancing learning. The authors have developed a computer-assisted learning (CAL) multimedia on vital signs with animation and audio features for teaching in the classroom based on the 5Es inquiry cycle. When the CAL was tried on second-year undergraduates in two comparable schools, all groups of students gained significantly higher performance skills regardless of whether the groups were subjected to CAL/lecture or CAL/lecture/demonstration. However, they did not gain in factual knowledge. PMID:18703258

The effect of intravenous Dexamethasone on post-cesarean section pain and vital signs: A double-blind randomized clinical trial  

PubMed Central

Objective: Any operation leads to body stress and tissue injury that causes pain and its complications. Glucocorticoids such as Dexamethasone are strong anti-inflammatory agents, which can be used for a short time post-operative pain control in various surgeries. Main purpose of this study is to evaluate the effect of administration of intravenous (IV) Dexamethasone on reducing the pain after cesarean. Methods: A double-blind prospective randomized clinical trial was performed on 60 patients candidate for elective caesarean section. Patients were randomly assigned into two groups: A (treatment: 8 mg IV Dexamethasone) and B (control: 2 mL normal saline). In both groups, variables such as mean arterial blood pressure (MAP), heart rate (HR), respiratory rate (RR), pain and vomiting severity (based on visual analog scale) were recorded in different time points during first 24 h after operation. Statistical methods using repeated measure analysis of variances and t-test, Mann-Whitney and Chi-square tests were used for analyzing data. Findings: The results indicated that within-group comparisons including severity of pain, MAP, RR and HR have significant differences (P < 0.001 for all variables) during the study period. Between group comparisons indicated significant differences in terms of pain severity (P < 0.001), MAP (P = 0.048) and HR (P = 0.078; marginally significant), which in case group were lower than the control group. Conclusion: IV Dexamethasone could efficiently reduce post-operative pain severity and the need for analgesic consumption and improve vital signs after cesarean section.

Noninvasive vital signal monitoring  

NASA Astrophysics Data System (ADS)

Vital signals of patients, such as heart rate, temperature and movement are crucial to monitor patients in hospital. Current heart rate measurement is obtained by using Electrocardiograph, which normally applies electrodes to the patient's body. As electrodes are extremely uncomfortable to ware and hinder patient's movement, a non-invasive vital signal-monitoring device will be a better solution. Similar to Electrocardiograph, the device detects the voltage difference across the heart by using concept of capacitance, which can be obtained by two conductive fiber sewing on the bed sheet. Simultaneous temperature reading can also be detected by using surface mounted temperature sensor. This paper will mainly focus on the heart rate monitoring.

Time: a vital resource.  

PubMed

Resolving problems with time management requires an understanding of the concept of working smarter rather than harder. Therefore, managing time effectively is a vital responsibility of department managers. When developing a plan for more effectively managing time, it is important to carefully analyze where time is currently being used/lost. Keeping a daily log can be a time consuming effort. However, the log can provide information about ways that time may be saved and how to organize personal schedules to maximize time efficiency. The next step is to develop a strategy to decrease wasted time and create a more cohesive radiology department. The following list of time management strategies provides some suggestions for developing a plan. Get focused. Set goals and priorities. Get organized. Monitor individual motivation factors. Develop memory techniques. In healthcare, success means delivering the highest quality of care by getting organized, meeting deadlines, creating efficient schedules and appropriately budgeting resources. Effective time management focuses on knowing what needs to be done when. The managerial challenge is to shift the emphasis from doing everything all at once to orchestrating the departmental activities in order to maximize the time given in a normal workday.

When longevity meets vitality.  

PubMed

Alarmed by the sustainability of our health and social security systems, longevity has become a great societal challenge. In line with evolutionary logic we see a continuous increase of average life expectancy and maximal lifespan. Striving for a healthy old age, however, is an infelicitous expression as for human subjects the ageing process cannot be ultimately postponed. Not disregarding the huge variation in health trajectories, in old age we will all suffer from frailty and infirmity. As yet efforts of the biomedical arena are almost exclusively focused on stalling the ageing process and preventing dysfunction. Too little effort is spend on how to inspire and coach the great majority of people who still feel relatively well notwithstanding the presence of multiple age-related disorders. There is a strong rationale to separate the quest to live in good health for longer from actively and effectively negotiating the challenge of functional decline in old age. In particular, we emphasise a focus on adjusting the environment in order to correct the gene-environment mismatch that contributes to ill health. An additional strategy is to empower people to set ambitions and to realise appropriate goals, in spite of infirmity. Striving for vitality presents a striking opportunity to achieve subjective feelings of life satisfaction when ageing. PMID:24804992

Vitalism and the Darwin Debate  

NASA Astrophysics Data System (ADS)

There are currently both scientific and public debates surrounding Darwinism. In the scientific debate, the details of evolution are in dispute, but not the central thesis of Darwin's theory; in the public debate, Darwinism itself is questioned. I concentrate on the public debate because of its direct impact on education in the United States. Some critics of Darwin advocate the teaching of intelligent design theory along with Darwin's theory, and others seek to eliminate even the mention of evolution from science classes altogether. Many of these critics base their objections on the claim that non-living matter cannot give rise to living matter. After considering some of the various meanings assigned to `vitalism' over the years, I argue that a considerable portion of Darwin deniers support a literal version of vitalism that is not scientifically respectable. Their position seems to be that since life cannot arise naturally, Darwin's theory accomplishes nothing: If it can only account for life forms changing from one to another (even this is disputed by some) but not how life arose in the first place, what's the point? I argue that there is every reason to believe that living and non-living matter differ only in degree, not in kind, and that all conversation about Darwinism should start with the assumption that abiogenesis is possible unless or until compelling evidence of its impossibility is presented. That is, I advocate a position that the burden of proof lies with those who claim "Life only comes from life." Until that case is made, little weight should be given to their position.

Battlefield triage life signs detection techniques  

NASA Astrophysics Data System (ADS)

Getting to wounded soldiers on the battlefield is a precarious task, and medics have a very high casualty rate. It is therefore a vital importance to prioritize which soldiers to attend to first. The first step is to detect life signs - if a soldier is dead or alive, and prioritize recovery of live soldiers. The second step is to obtain vital signs from live soldiers, and use this to prioritize which are in most urgent need of attention. Our team at Kai Sensors, University of Hawaii and University of Florida is developing Doppler radar heart sensing technology that provides the means to detect life signs, respiration and/or heart beat, at a distance, even for subjects lying motionless, e.g., unconscious subjects, wearing body armor, and hidden from direct view. Since this technology can deliver heart rate information with high accuracy, it may also enable the assessment of a subject's physiological and psychological state based on heart rate variability (HRV) analysis. Thus, the degree of a subject's injury may also be determined. The software and hardware developments and challenges for life signs detection and monitoring for battlefield triage will be discussed, including heart signal detection from all four sides of the human body, detection in the presence of body armor, and the feasibility of HRV parameter extraction.

Vital physical signals measurements using a webcam  

NASA Astrophysics Data System (ADS)

Non-contact and remote measurements of vital physical signals are important for reliable and comfortable physiological self-assessment. In this paper, we provide a new video-based methodology for remote and fast measurements of vital physical signals such as cardiac pulse and breathing rate. A webcam is used to track color video of a human face or wrist, and a Photoplethysmography (PPG) technique is applied to perform the measurements of the vital signals. A novel sequential blind signal extraction methodology is applied to the color video under normal lighting conditions, based on correlation analysis between the green trace and the source signals. The approach is successfully applied in the measurement of vital signals under the condition of different illuminating in which the target signal can also be found out accurately. To assess the advantages, the measuring time of a large number of cases is recorded correctly. The experimental results show that it only takes less than 30 seconds to measure the vital physical signals using presented technique. The study indicates the proposed approach is feasible for PPG technique, which provides a way to study the relationship of the signal for different ROI in future research.

Reservoir vital signs monitoring, 1992: Bacteriological conditions in the Tennessee Valley. Fourth annual report  

SciTech Connect

Twenty-eight designated swimming beaches, four informal swimming areas, two canoe launching or landing sites, and two additional sites on a canoeing stream were sampled at least ten times each during 30-day sampling periods in the summer of 1992. One designated swimming beach, one informal swimming area, and two canoe launching or landing sites exceeded the recommended criterion of geometric mean concentrations of fecal coliform bacteria of 200/100 mL. In addition to these four sites, five designated swimming beaches and one informal swimming area exceeded the US Environmental Protection Agency (EPA) recommended criterion by having more than 10 percent of the fecal coliform samples with concentrations greater than 400/100 mL. Rainfall was an important factor for these six sites and the four sites that did not meet the geometric mean criterion. Some sampling sites are affected by rainfall more than others. When bacteria concentrations increase after rainfall, it indicates that site is vulnerable to contamination from nonpoint sources of pollution. Recreational use of these sites following rainfall is discouraged. If samples collected within 24 hours of rainfall (one-half inch or more) are excluded, all-but one of the ten sites have better bacteriological water quality, and two meet both the geometric mean and maximum concentration criteria. Five canoe access locations on the Bear Creek floatway, plus one site upstream and another downstream of the floatway were sampled eight times each during 1992. All seven sites met recreation criteria.

Textile technology for the vital signs monitoring in telemedicine and extreme environments.  

PubMed

This paper illustrates two extensive applications of a smart garment we previously developed for the monitoring of ECG, respiration, and movement. In the first application, the device, named Maglietta Interattiva Computerizzata (MagIC), was used for the home monitoring of cardiac patients. The used platform included MagIC for signals collection, a touchscreen computer with a dedicated software for data handling, and a universal mobile telecommunications system (UMTS) dongle for data transmission, via email, to three cardiologists. Three patients daily-performed 3-min telemonitoring sessions for 30 days by using the platform. The whole system behaved correctly in 85 out of 90 sessions. In five instances, a second session was required due to UMTS traffic congestion. Only in three sessions, cardiologists asked the patient to repeat the acquisition because of poor signal quality. In the second application, MagIC was used to evaluate the effects of high-altitude hypoxia on sleep and 24 h daily life in 30 healthy subjects at 3500 and 5400 m above sea level on Mount Everest slopes. The use of MagIC garment was reported to be simple and requiring short instrumentation time even in the demanding expedition environment. The signal quality was adequate in 111 out of 115 recordings and 90% of the subjects found the vest comfortable. PMID:20421189

Vital signs: disability and physical activity - United States, 2009-2012.  

PubMed

Background: Adults with disabilities are less active and have higher rates of chronic disease than the general population. Given the health benefits of physical activity, understanding physical activity, its relationship with chronic disease, and health professional recommendations for physical activity among young to middle-age adults with disabilities could help increase the effectiveness of health promotion efforts. Methods: Data from the 2009-2012 National Health Interview Survey (NHIS) were used to estimate the prevalence of, and association between, aerobic physical activity (inactive, insufficiently active, or active) and chronic diseases (heart disease, stroke, diabetes, and cancer) among adults aged 18-64 years by disability status and type (hearing, vision, cognitive, and mobility). The prevalence of, and association between, receiving a health professional recommendation for physical activity and level of aerobic physical activity was assessed using 2010 data. Results: Overall, 11.6% of U.S. adults aged 18-64 years reported a disability, with estimates for disability type ranging from 1.7% (vision) to 5.8% (mobility). Compared with adults without disabilities, inactivity was more prevalent among adults with any disability (47.1% versus 26.1%) and for adults with each type of disability. Inactive adults with disabilities were 50% more likely to report one or more chronic diseases than those who were physically active. Approximately 44% of adults with disabilities received a recommendation from a health professional for physical activity in the past 12 months. Conclusions: Almost half of adults with disabilities are physically inactive and are more likely to have a chronic disease. Among adults with disabilities who visited a health professional in the past 12 months, the majority (56%) did not receive a recommendation for physical activity. Implications for Public Health: These data highlight the need for increased physical activity among persons with disabilities, which might require support across societal sectors, including government and health care.

Wireless Body Sensor Network for low-power motion-tolerant synchronized vital sign measurement.  

PubMed

Prophylaxis and rehabilitation of cardiovascular disease require the development of biosignal acquisition and processing devices that are capable of supporting patients in their everyday life. This paper presents a Body Sensor Network (BSN) for use in Personal Healthcare applications. It consists of miniaturized sensor modules for electrocardiogram (ECG), photoplethysmogram (PPG) and phonocardiography (PCG) which are wirelessly connected with a coordinator to collect the data. Each sensor module is combined with a tri-axis accelerometer for patient's posture and activity measurement. As it is possible to extract further information about the health state by fusioning data of different biosensors, the wireless link based on IEEE 802.15.4 was extended by a synchronisation mechanism enabling synchronous sampling of the individual sensors. An adaptive application of algorithms for signal pre-processing and analysis allows the reduction of the transferred data. PMID:19163444

Stable isotope `vital effects' in coccolith calcite  

NASA Astrophysics Data System (ADS)

Uncertainties about the origin of the many disequilibrium or 'vital effects' in a variety of calcifying organisms, and whether these effects are constant or variable, have hampered paleoceanographic application of carbon and oxygen isotopic ratios. Unraveling the source of these effects will improve paleoceanographic applications and may provide new information on changes in cell physiology and ecology. Culture of eight species of coccolithophorids, a dominant marine phytoplankton group, reveals a 5‰ array of disequilibrium or 'vital effects' in both the carbon and oxygen isotopic composition of coccolith calcite. In moderate light and nutrient-replete cultures, oxygen isotopic fractionation and carbon isotopic fractionation correlates directly with cell division rates and correlates inversely with cell size across a range of species. However, when growth rates of a single species are increased or decreased by higher or lower light levels, ? 18O is relatively invariant. Likewise, growth rate variations as a function of temperature do not influence coccolith ? 18O; the slope of the ? 18O vs. temperature relation in cultures of both Gephyrocapsa oceanica and Helicosphaera carteri is the same as for abiogenic carbonates. This suggests a constant, species-specific isotopic fractionation which does not vary with cell physiology. The constancy of vital effects suggests that coccolith stable isotopes will provide reliable phase for paleoceanographic reconstruction of temperature and seawater chemistry, as long as monospecific fractions are analyzed or changes in nannofossil assemblages are accounted for with species-specific correction factors. We suspect that the cell size, and its constraints on the rate of CO 2 diffusion relative to C fixation, may be the first order influence on coccolith stable isotope vital effects. A quantitative model of this process may provide important constraints on mechanisms of carbon acquisition of coccolithophorids in both modern and extinct species.

Sign detection for autonomous navigation  

NASA Astrophysics Data System (ADS)

Mobile robots currently cannot detect and read arbitrary signs. This is a major hindrance to mobile robot usability, since they cannot be tasked using directions that are intuitive to humans. It also limits their ability to report their position relative to intuitive landmarks. Other researchers have demonstrated some success on traffic sign recognition, but using template based methods limits the set of recognizable signs. There is a clear need for a sign detection and recognition system that can process a much wider variety of signs: traffic signs, street signs, store-name signs, building directories, room signs, etc. We are developing a system for Sign Understanding in Support of Autonomous Navigation (SUSAN), that detects signs from various cues common to most signs: vivid colors, compact shape, and text. We have demonstrated the feasibility of our approach on a variety of signs in both indoor and outdoor locations.

The Meaning of Signs:  

PubMed Central

This article reconstructs the diagnostic act of the French pox in the French-disease hospital of sixteenth-century Augsburg. It focuses on how the participants in the clinical encounter imagined the configuration of the pox and its localization in the human body. Of central importance for answering this question is the early modern conception of physical signs. It has been argued that it was due to a specific understanding of bodily signs and their relationship to a disease and its causes, that disease definition and classification in the early modern period showed a high degree of flexibility and fluidity. This paper looks at how the sixteenth-century theoretical conception of physical signs not only shaped the diagnosis and treatment of the pox but also reflected the overall organization of institutions.

Prosthodontic Treatment Using Vital and Non Vital Submerged Roots-Two Case Reports  

PubMed Central

Residual ridge resorption has been considered as an inevitable consequence after extraction of the teeth. There is a gradual loss of the alveolar bone due to the pattern of bone remodeling. In spite of the availability of newer treatment modalities like endodontic restoration and periodontic procedures for preservation of the remaining teeth they are not feasible for the patients in severe stages where restoration might not be possible. The only reliable method of preserving the remaining bone is by maintaining the functional health of the teeth. Over the years, many studies showed that roots which are fractured and left behind during extractions are retained into the alveolar bone with no evidence of pathosis. Over denture as a treatment option was developed in an effort to preserve the remaining alveolar bone by retaining the natural teeth or roots. In over denture treatment, the teeth selected as abutments are prone to caries and periodontal disease over a period of time, hence evolved the vital or non vital root submergence concept. After a thorough radiographic and clinical examination, few teeth without pathosis are retained that eventually are surgically submerged in the alveolar ridge. After healing, the over denture with reaining vital or non vital teeth preserve the integrity of the bone, making the treatment an effective and successfull preventive prosthodontic treatment.

Activated barrier for protection of special nuclear materials in vital areas  

SciTech Connect

The Argonne National Laboratory and Sandia National Laboratory have recently installed an activated barrier, the Access Denial System (ADS) for the upgrade of safeguards of special nuclear materials. The technology of this system was developed in the late 70's by Sandia National Laboratory-Albuquerque. The installation was the first for the Department of Energy. Subsequently, two additional installations have been completed. The Access Denial System, combined with physical restraints, provide the system delay. The principal advantages of the activated barrier are: (1) it provides an order of magnitude improvement in delay over that of a fixed barrier, (2) it can be added to existing vital areas with a minimum of renovations, (3) existing operations are minimally impacted, and (4) health and safety risks are virtually nonexistent. Hardening of the vital areas using the ADS was accomplished in a cost-effective manner. 3 references, 1 figure, 1 table.

Effect of Vitality on Translucent Dentine - A Study  

PubMed Central

Background: Sclerosis of dentinal tubules may be a response to pathological or physiological insult in the crown & root. The mechanism by which apical translucency is produced is still uncertain. The increase in size of the apical zone of sclerotic dentin in human teeth has been used often in forensic science as a method of age estimation. However, only few studies have been done to compare percentage of translucency between vital and non-vital teeth. Conflicting concepts exist regarding the amount of translucent dentin in the vital & non vital teeth and correlation of this variation with age of the subject. Aims: To investigate the amount and distribution of apical translucent dentin in group-matched vital and non-vital teeth. Materials and methods: Study was conducted on 70 extracted teeth, which were subjected for vitality test before extraction, and divided into two groups (vital & non-vital teeth) with a minimum of 35 teeth in each group. Ground sections of 150µ thickness were observed under Stereomicroscope and photographed. The distribution of area and length was measured on the images captured, using PROPLUS IMAGE ANALYSIS SOFTWARE version 4.1.0.0 software. Results and Conclusions: The present study revealed significant differences (p < 0.05) in apical translucency of dentin, when both vital and non-vital teeth types were compared. There was more apical translucency present in non-vital when compared with vital teeth at any given age.

Road sign detection and recognition  

NASA Astrophysics Data System (ADS)

Road sign detection is important to a robotic vehicle that automatically drives on roads. In this paper, road signs are detected by means of rules that restrict color and shape and require signs to appear only in limited regions in an image. They are then recognized using a template matching method and tracked through a sequence of images. The method is fast and can easily be modified to include new classes of signs. The road sign detection is used as part of a control system that autonomously drives a vehicle over paved roads. The primary application is to detect intersections, which are usually marked with street name signs or stop signs. An estimate of the range to the sign is computed based on the size of the sign and provides a cue to intersection detection software and driving control.

Pulse microwave effects on nerve vitality  

SciTech Connect

Isolated sciatic nerves of frogs were exposed to 2.45-GHz pulse-microwave radiation in a waveguide exposure system at an average specific absorption rate (SAR) of 10 mW/g. In previous studies using continuous-wave (cw) microwave radiation at an SAR of 10 mW/g, survival time of the irradiated nerve when stimulated to fire at a high rate (50 twin pulses per sec) was shorteded significantly. This investigation was performed to determine if pulse-microwave radiation produced the same of different effects on the vitality of frog sciatic nerves as continuous-wave microwave radiation. Three sets of experiments were carried out using 10-..mu..sec-wide pulses at 50 pps, with an average SAR of 10 mW/g: (1) asynchronous pulsing wherein the mw pulse was delivered at varying times in the firing cycle; (2) synchronous pulsing during the peak of the nerve action potential; and (3) synchronous pulsing during the quiescent period between nerve firings. In all three cases a significant decrease in the survival time of the exposed nerves, as compared to their unexposed mates, was seen. However, the magnitude of this effect was essentially the same in all three cases and was also comparable with the ffect seen earlier using cw (of equivalent SAR).

Landsat 6 contract signed  

NASA Astrophysics Data System (ADS)

A new agreement provides $220 million for development and construction of the Landsat 6 remote sensing satellite and its ground systems. The contract, signed on March 31, 1988, by the Department of Commerce (DOC) and the Earth Observation Satellite (EOSAT) Company of Lanham, Md., came just days after approval of DOC's Landsat commercialization plan by subcommittees of the House and Senate appropriations committees.The Landsat 6 spacecraft is due to be launched into orbit on a Titan II rocket in June 1991 from Vandenburg Air Force Base, Calif. The satellite will carry an Enhanced Thematic Mapper (ETM) sensor, an instrument sensitive to electromagnetic radiation in seven ranges or bands of wavelengths. The satellite's payload will also include the Sea Wide Field Sensor (Sea-WiFS), designed to provide information on sea surface temperature and ocean color. The sensor is being developed in a cooperative effort by EOSAT and the National Aeronautics and Space Administration (NASA). A less certain passenger is a proposed 5-m resolution, three-band sensor sensitive to visible light. EOSAT is trying to find both private financing for the device and potential buyers of the high-resolution imagery that it could produce. The company has been actively courting U.S. television networks, which have in the past used imagery from the European Système Probatoire d'Observation de la Terre (SPOT) satellite for news coverage.

The effects of sign design features on bicycle pictorial symbols for bicycling facility signs.  

PubMed

The inanimate bicycle symbol has long been used to indicate the animate activity of bicycling facility signs. In contrast, either the inanimate bicycle symbol or the animate bicycle symbol has been used interchangeably for the standard pavement symbols in bike lanes. This has led to confusion among pedestrians and cyclists alike. The purpose of this study was to examine two different designs (inanimate symbol vs. animate symbol) involved in the evaluation of perceived preference and glance legibility, and investigate sign design features on bicycle pictorial symbols. Thirty-five participants compared current bicycle signs (inanimate symbols) to alternative designs (animate symbols) in a controlled laboratory setting. The results indicated that the alternative designs (animate symbols) showed better performance in both preference and glance legibility tests. Conceptual compatibility, familiarity, and perceptual affordances were found to be important factors as well. PMID:23623234

Standard circumstances and vital goals: comments on Venkatapuram's critique.  

PubMed

This article is a reply to Venkatapuram's critique in his article Health, Vital Goals, Capabilities, this volume. I take issue mainly with three critical points put forward by Venkatapuram with regard to my theory of health. (1) I deny that the contents of my vital goals are relative to each community or context, as Venkatapuram claims. There is no conceptual connection at all between standard circumstances and vital goals, as I understand these concepts. (2) Venkatapuram notes that I stop short of filling the framework of vital goals with any content and thereby make my concept of health less concrete. I reply that some vital goals are indeed universal, viz. the ones which are necessary conditions for survival. Many other vital goals are individual and cannot therefore be included in a universal list. (3) Venkatapuram claims that my definition of vital goals is too broad, since it entails that some persons without any disease can be regarded as ill. However, in my understanding health is a relational concept from a state of complete health to a state of maximal illness. In this framework, a minor reduction of a state of complete health does not entail illness. This article also contains a comparison between my theory of health and Martha Nussbaum's theory of capabilities for dignity. PMID:22420285

Waist circumference as a vital sign in cardiology 20 years after its initial publication in the american journal of cardiology.  

PubMed

In 1994, we reported in The American Journal of Cardiology that a simple anthropometric measurement, waist circumference, was related to the amount of abdominal visceral adipose tissue measured by computed tomography. An elevated waist circumference was also found to be associated with several features of the cardiometabolic risk profile such as glucose intolerance, hyperinsulinemia, and an atherogenic dyslipidemic profile that included hypertriglyceridemia and reduced high-density lipoprotein cholesterol levels. Although a linear relation was found between waist circumference and these metabolic alterations, we reported that a waist circumference value of about 100 cm was associated with a high probability of finding diabetogenic and atherogenic abnormalities. The present short report provides a brief update of issues that have been raised regarding the measurement of waist circumference and its clinical use over a period of 20 years since the original publication.

Vital Signs: Fatalities and Binge Drinking Among High School Students: A Critical Issue to Emergency Departments and Trauma Centers  

PubMed Central

The Centers for Disease Control and Prevention (CDC) has published significant data and trends related to drinking and driving among United States (U.S.) high school students. National data from 1991–2011 shows an overall 54% relative decrease (from 22% to 10.3%) in drinking and driving among U.S. high school students aged ? 16 years. In 2011, this still represents approximately 950,000 high school students ages 16–19 years. The decrease in drinking and driving among teens is not fully understood, but is believed to be due to policy developments, enforcement of laws, graduated licenses, and economic impacts. Most significant to emergency physicians is that even with these restrictions, in 2010 approximately 2,700 teens (ages 16–19) were killed in the U.S. and about 282,000 were treated and released from emergency departments for injuries suffered in motor-vehicle accidents. In the same year, 1 in 5 drivers between the ages of 16–19 who were involved in fatal crashes had positive (>0.00%) blood alcohol concentration (BAC). We present findings from the CDC's Morbidity and Mortality Weekly Report with commentary on current recommendations and policies for reducing drinking and driving among adolescents.

Real-Time Detection and Tracking of Vital Signs with an Ambulatory Subject Using Millimeter-Wave Interferometry  

NASA Astrophysics Data System (ADS)

Finding a subject's heart rate from a distance without any contact is a difficult and very practical problem. This kind of technology would allow more comfortable patient monitoring in hospitals or in home settings. It would also allow another level of security screening, as a person's heart rate increases in stressful situations, such as when lying or hiding malicious intent. In addition, the fact that the heart rate is obtained remotely means that the subject would not have to know he/she is being monitored at all, adding to the efficacy of the measurement. Using millimeter-wave interferometry, a signal can be obtained that contains composite chest wall motion made up of component motions due to cardiac activity, respiration, and interference. To be of use, these components have to be separated from each other by signal processing. To do this, the quadrature and in-phase components of the received signal are analyzed to get a displacement waveform. After that, processing can be done on that waveform in either the time or frequency domains to find the individual heartbeats. The first method is to find the power spectrum of the displacement waveform and to look for peaks corresponding to heartbeats and respiration. Another approach is to examine the signal in the time domain using wavelets for multiresolution analysis. One more method involves studying the statistics of the wavelet-processed signal. The final method uses a heartbeat model along with probabilistic processing to find heartbeats. For any of the above methods to work, the millimeter-wave sensor has to be accurately pointed at the subject's chest. However, even small subject motions can render the rest of the gathered data useless as the antenna may have lost its aim. To combat this, a color and a depth camera are used with a servo-pan/tilt base. My program finds a face in the image and subsequently tracks that face through upcoming frames. The pan/tilt base adjusts the aim of the antenna depending on the subject's position. This makes the entire system self-aiming and also allows the subject to move to a new location and to have data acquisition continue.

Ecological thresholds as a basis for defining management triggers for National Park Service vital signs: case studies for dryland ecosystems  

USGS Publications Warehouse

Threshold concepts are used in research and management of ecological systems to describe and interpret abrupt and persistent reorganization of ecosystem properties (Walker and Meyers, 2004; Groffman and others, 2006). Abrupt change, referred to as a threshold crossing, and the progression of reorganization can be triggered by one or more interactive disturbances such as land-use activities and climatic events (Paine and others, 1998). Threshold crossings occur when feedback mechanisms that typically absorb forces of change are replaced with those that promote development of alternative equilibria or states (Suding and others, 2004; Walker and Meyers, 2004; Briske and others, 2008). The alternative states that emerge from a threshold crossing vary and often exhibit reduced ecological integrity and value in terms of management goals relative to the original or reference system. Alternative stable states with some limited residual properties of the original system may develop along the progression after a crossing; an eventual outcome may be the complete loss of pre-threshold properties of the original ecosystem. Reverting to the more desirable reference state through ecological restoration becomes increasingly difficult and expensive along the progression gradient and may eventually become impossible. Ecological threshold concepts have been applied as a heuristic framework and to aid in the management of rangelands (Bestelmeyer, 2006; Briske and others, 2006, 2008), aquatic (Scheffer and others, 1993; Rapport and Whitford 1999), riparian (Stringham and others, 2001; Scott and others, 2005), and forested ecosystems (Allen and others, 2002; Digiovinazzo and others, 2010). These concepts are also topical in ecological restoration (Hobbs and Norton 1996; Whisenant 1999; Suding and others, 2004; King and Hobbs, 2006) and ecosystem sustainability (Herrick, 2000; Chapin and others, 1996; Davenport and others, 1998). Achieving conservation management goals requires the protection of resources within the range of desired conditions (Cook and others, 2010). The goal of conservation management for natural resources in the U.S. National Park System is to maintain native species and habitat unimpaired for the enjoyment of future generations. Achieving this goal requires, in part, early detection of system change and timely implementation of remediation. The recent National Park Service Inventory and Monitoring program (NPS I&M) was established to provide early warning of declining ecosystem conditions relative to a desired native or reference system (Fancy and others, 2009). To be an effective tool for resource protection, monitoring must be designed to alert managers of impending thresholds so that preventive actions can be taken. This requires an understanding of the ecosystem attributes and processes associated with threshold-type behavior; how these attributes and processes become degraded; and how risks of degradation vary among ecosystems and in relation to environmental factors such as soil properties, climatic conditions, and exposure to stressors. In general, the utility of the threshold concept for long-term monitoring depends on the ability of scientists and managers to detect, predict, and prevent the occurrence of threshold crossings associated with persistent, undesirable shifts among ecosystem states (Briske and others, 2006). Because of the scientific challenges associated with understanding these factors, the application of threshold concepts to monitoring designs has been very limited to date (Groffman and others, 2006). As a case in point, the monitoring efforts across the 32 NPS I&M networks were largely designed with the knowledge that they would not be used to their full potential until the development of a systematic method for understanding threshold dynamics and methods for estimating key attributes of threshold crossings. This report describes and demonstrates a generalized approach that we implemented to formalize understanding and estimating of threshold dynamics for terrestrial dryland ecosystems in nationa

A vital signs telemonitoring system - interoperability supported by a personal health record systema and a cloud service.  

PubMed

This article presents the development process of an acquisition and data storage system managing clinical variables through a cloud storage service and a Personal Health Record (PHR) System. First, the paper explains how a Wireless Body Area Network (WBAN) that captures data from two sensors corresponding to arterial pressure and heart rate is designed. Second, this paper illustrates how data collected by the WBAN are transmitted to a cloud storage service. It is worth mentioning that this cloud service allows the data to be stored in a persistent way on an online database system. Finally, the paper describes, how the data stored in the cloud service are sent to the Indivo PHR System, where they are registered and charted for future revision by health professionals. The research demonstrated the feasibility of implementing WBAN networks for the acquisition of clinical data, and particularly for the use of Web technologies and standards to provide interoperability with PHR Systems at technical and syntactic levels.

Monitoring Vital Signs: Development of a Modified Early Warning Scoring (Mews) System for General Wards in a Developing Country  

PubMed Central

Objective The aim of the study was to develop and validate, by consensus, the construct and content of an observations chart for nurses incorporating a modified early warning scoring (MEWS) system for physiological parameters to be used for bedside monitoring on general wards in a public hospital in South Africa. Methods Delphi and modified face-to-face nominal group consensus methods were used to develop and validate a prototype observations chart that incorporated an existing UK MEWS. This informed the development of the Cape Town ward MEWS chart. Participants One specialist anaesthesiologist, one emergency medicine specialist, two critical care nurses and eight senior ward nurses with expertise in bedside monitoring (N?=?12) were purposively sampled for consensus development of the MEWS. One general surgeon declined and one neurosurgeon replaced the emergency medicine specialist in the final round. Results Five consensus rounds achieved ?70% agreement for cut points in five of seven physiological parameters respiratory and heart rates, systolic BP, temperature and urine output. For conscious level and oxygen saturation a relaxed rule of <70% agreement was applied. A reporting algorithm was established and incorporated in the MEWS chart representing decision rules determining the degree of urgency. Parameters and cut points differed from those in MEWS used in developed countries. Conclusions A MEWS for developing countries should record at least seven parameters. Experts from developing countries are best placed to stipulate cut points in physiological parameters. Further research is needed to explore the ability of the MEWS chart to identify physiological and clinical deterioration.

Selected publication trends in JEAB: Implications for the vitality of the experimental analysis of behavior  

PubMed Central

To provide some insight into the current vitality of the experimental analysis of behavior, we updated and extended an analysis by R. A. Williams and Buskist (1983) of selected trends in the Journal of the Experimental Analysis of Behavior. Specifically, the number of articles published and the percentage of those articles that were empirical, the number of different affiliations of authors and number of articles per affiliation, the types of subjects used in empirical articles, and the topics investigated were analyzed for the years 1958 through 1999. Although several trends may point to a decline in the overall well-being of the experimental analysis of behavior, they may also be interpreted as signs of progress for the field.

Turnaround time (TAT) is one of the most noticeable signs of laboratory service and is often used as a key performance indicator of laboratory performance. This review summarises the literature regarding laboratory TAT, focusing on the different definitions, measures, expectations, published data, associations with clinical outcomes and approaches to improve TAT. It aims to provide a consolidated source of benchmarking data useful to the laboratory in setting TAT goals and to encourage introduction of TAT monitoring for continuous quality improvement. A 90% completion time (sample registration to result reporting) of <60 minutes for common laboratory tests is suggested as an initial goal for acceptable TAT.

Vital effects in coccolith calcite: Cenozoic climate-pCO2 drove the diversity of carbon acquisition strategies in coccolithophores?  

NASA Astrophysics Data System (ADS)

Coccoliths, calcite plates produced by the marine phytoplankton coccolithophores, have previously shown a large array of carbon and oxygen stable isotope fractionations (termed "vital effects"), correlated to cell size and hypothesized to reflect the varying importance of active carbon acquisition strategies. Culture studies show a reduced range of vital effects between large and small coccolithophores under high CO2, consistent with previous observations of a smaller range of interspecific vital effects in Paleocene coccoliths. We present new fossil data examining coccolithophore vital effects over three key Cenozoic intervals reflecting changing climate and atmospheric partial pressure of CO2 (pCO2). Oxygen and carbon stable isotopes of size-separated coccolith fractions dominated by different species from well preserved Paleocene-Eocene thermal maximum (PETM, ˜56 Ma) samples show reduced interspecific differences within the greenhouse boundary conditions of the PETM. Conversely, isotope data from the Plio-Pleistocene transition (PPT; 3.5-2 Ma) and the last glacial maximum (LGM; ˜22 ka) show persistent vital effects of ˜2‰. PPT and LGM data show a clear positive trend between coccolith (cell) size and isotopic enrichment in coccolith carbonate, as seen in laboratory cultures. On geological timescales, the degree of expression of vital effects in coccoliths appears to be insensitive topCO2 changes over the range ˜350 ppm (Pliocene) to ˜180 ppm (LGM). The modern array of coccolith vital effects arose after the PETM but before the late Pliocene and may reflect the operation of more diverse carbon acquisition strategies in coccolithophores in response to decreasing Cenozoic pCO2.

xdamp: An IDL{reg_sign}-based Data Manipulation Program  

SciTech Connect

The original DAMP (DAta Manipulation Program) was written by Mark Hedemann of Sandia National Laboratories and used the CA-DISSPLA{trademark} (available from Computer Associates International, Inc., Garden City, NY) graphics package as its engine. It was used to plot, modify, and otherwise manipulate the one-dimensional data waveforms (data vs time) from a wide variety of accelerators. With the waning of CA-DISSPLA and the increasing popularity of UNIX{reg_sign}-based workstations, a replacement was needed. This package uses the IDL{reg_sign} software, available from Research Systems Incorporated in Boulder, Colorado, as the engine, and creates a set of widgets to manipulate the data in a manner similar to the original DAMP. IDL is currently supported on a wide variety of UNIX platforms such as IBM{reg_sign} workstations, Hewlett Packard workstations, SUN{reg_sign} workstations, Microsoft{reg_sign} Windows{trademark} computers, Macintosh{reg_sign} computers and Digital Equipment Corporation VMS{reg_sign} systems. Thus, this program should be portable across many platforms. We have verified operation, albeit with some IDL bugs, on IBM UNIX platforms, DEC Alpha systems, HP 9000/7OO series workstations, and Macintosh computers, both regular and PowerPC{trademark} versions.

Signs of Life on Venus  

NASA Astrophysics Data System (ADS)

The search for "habitable zones" in extrasolar planetary systems is based on the premise of "normal" physical conditions in a habitable zone, i.e. pressure, temperature range, and atmospheric composition similar to those on the Earth. However, one should not exclude completely the possibility of the existence of life at relatively high temperatures, despite the fact that at the first glance it seems impossible. The planet Venus with its dense, hot (735 K), oxigenless CO2 - atmosphere and high 92 bar-pressure at the surface could be the natural laboratory for the studies of this type. Amid exoplanets, celestial bodies with the physical conditions similar to the Venusian can be met. The only existing data of actual close-in observations of Venus' surface are the results of a series of missions of the soviet VENERA landers which took place the 1970's and 80's in the atmosphere and on the surface of Venus. For 36 and 29 years since these missions, respectively, I repeatedly returned to the obtained images of the Venus' surface in order to reveal on them any unusual objects observed in the real conditions of Venus. The new analysis of the Venus' panoramas was based on the search of unusual elements in two ways. Since the efficiency of the VENERA landers maintained for a long time they produced a large number of primary television panoramas during the lander's work. Thus, one can try to detect: (a) any differences in successive images (appearance or disappearance of parts of the image or change of their shape), and understand what these changes are related to (e.g., wind), and whether they are related to hypothetical habitability of a planet. Another sign (b) of the wanted object is their morphological peculiarities which distinguishes them from the ordinary surface details. The results of VENERA-9 (1975) and VENERA -13 (1982) are of the main interest. A few relatively large objects ranging from a decimeter to half meter and with unusual morphology were observed in some images, but were absent in the other or altered their shape. What sources of energy, in principle, could be used by life in the high temperature oxigenless atmosphere? The objects found are large enough, they are not micro-organisms. It is most natural to assume that, like on Earth, Venusian fauna is heterotrophic, and the source of its life is hypothetical autotrophic flora. There is enough light for flora's photosynthesis. Since the critical temperature of water on Venus is about 320°C and the temperature at the surface is about 460°C, the metabolism of organisms on Venus (if any) should be built without water, on the basis of some other liquid medium. Based on data analyzed it has been suggested that because of the limited energy capacity of the Venusian fauna, the temporal characteristics of their physical actions can be much longer than that of the Earth.

Astrological birth signs in suicide: hypothesis or speculation?  

PubMed

Astrology is no longer regarded as a science by many, because its claims are almost impossible to test empirically in controlled laboratory conditions and it can not meet the scientific need to be reproducible. However, the majority of those who read their 'star signs' can identify aspects of their personality in what they read and it is possible that this may influence their attitudes and actions. The literature has neglected astrological signs as a possible predictor of suicide ideation. To see whether astrological birth signs are associated with suicide and the method used, data was collected from the Public Health Department in North Cheshire representing all the Cheshire Coroner's verdicts of suicide, and open verdicts, in all deceased aged 60 and above between 1989 and 2000. The observed occurrence of deaths due to natural causes, and suicide, in relation to birth signs did not differ significantly from what would be expected from chance. However, the distribution of suicide by hanging appeared significantly higher in those with a birth sign of Virgo and lowest in Sagittarius and Scorpio. The distribution of violent and non-violent suicides in relation to star signs showed higher occurences of violent death in persons born in the summer months. PMID:12741653

Validating the Vitality Strategy for Fighting Drug Resistance  

PubMed Central

The current challenge in designing effective drugs against HIV-1 is to find novel candidates with high potency, but with a lower susceptibility to mutations associated with drug resistance. Trying to address this challenge we developed in our previous study1 a novel computational strategy for fighting drug resistance by predicting the likely moves of the virus through constraints on binding and catalysis. This has been based on calculating the vitality values (defined as the ratio ((Kikcat/KM)mutant/ (Kikcat/KM)wild-type) and using it as guide for the moves of the virus. The corresponding calculations of the binding affinity, Ki, were based on using the semi-macroscopic version of the protein dipole Langevin dipole (PDLD/S) in its linear response approximation (LRA) in its ? version (PDLD/S-LRA/?). We, also, calculate the proteolytic efficiency, kcat/KM, by evaluating the transition state (TS) binding free energies using the PDLD/S-LRA/? method. Here we provide an extensive validation of our strategy by calculating the vitality of six existing clinical and experimental drug candidates. It is found that the computationally determined vitalities correlate reasonably well with those derived from the corresponding experimental data. This indicates that the calculated vitality may be used to identify mutations that would be most effective for the survival of the virus. Thus, it should be possible to use our approach in screening for mutations that would provide the most effective resistance to any proposed antiviral drug. This ability should be very useful in guiding the design of drug molecules that will lead to the slowest resistance.

Strengthening ecological mindfulness through hybrid learning in vital coalitions  

NASA Astrophysics Data System (ADS)

In this contribution a key policy `tool' used in the Dutch Environmental Education and Learning for Sustainability Policy framework is introduced as a means to develop a sense of place and associated ecological mindfulness. The key elements of this tool, called the vital coalition, are described while an example of its use in practice, is analysed using a form of reflexive monitoring and evaluation. The example focuses on a multi-stakeholder learning process around the transformation of a somewhat sterile pre-school playground into an intergenerational green place suitable for play, discovery and engagement. Our analysis of the policy-framework and the case leads us to pointing out the importance of critical interventions at so-called tipping points within the transformation process and a discussion of the potential of hybrid learning in vital coalitions in strengthening ecological mindfulness. This paper does not focus on establishing an evidence base for the causality between this type of learning and a change in behavior or mindfulness among participants as a result contributing to a vital coalition but rather focusses on the conditions, processes and interventions that allow for such learning to take place in the first place.

Tryptase, CD15 and IL-15 as reliable markers for the determination of soft and hard ligature marks vitality.  

PubMed

In forensic practice, it is required to distinguish between suicidal or accidental hanging and simulated hanging. Conventional macroscopic and histological findings may be unreliable; vital signs are often absent, and they can be produced postmortem. The application of immunohistochemical techniques opened up a new field of investigation in the issue of ligature marks. We investigated the immunohistochemical expression of a panel of cytokines and inflammatory cells in skin specimens in autopsy cases of death due to hanging, to discuss their significance in assessing whether hanging mark and signs occurred before or after the death of the victim. We selected 21 cases in which broad, soft and yielding materials were used and 28 cases in which materials used for hanging were hard. The control group included the following 21 cases: 14 cases of sudden cardiac death and 7 cases of post-mortem hanging (suspension) of bodies (drug overdose or suffocation as cause of death in all the cases). An immunohistochemical investigation of skin samples was performed utilizing antibodies anti- tryptase, fibronectin, TNFa, IL-6, IL-8, IL-10, MCP-1, IL-15, IL-1ß, CD45, CD4, CD3, CD8, CD68, CD20, CD15. We conclude that tryptase, IL-15, and CD15 appear to be reliable parameters in the determination of ligature marks' vitality with the accuracy needed for forensic purposes. This fact especially applies to soft marks which are particularly difficult to evaluate on the basis of gross examination and of conventional histological studies. PMID:20886434

Attachment of different soil bacteria to arbuscular mycorrhizal fungal extraradical hyphae is determined by hyphal vitality and fungal species.  

PubMed

Attachment of certain bacteria to living arbuscular mycorrhizal fungal extraradical hyphae may be an important prerequisite for interactions between these microorganisms, with implications for nutrient supply and plant health. The attachment of five different strains of gfp-tagged soil bacteria (Paenibacillus brasilensis PB177 (pnf8), Bacillus cereus VA1 (pnf8), Pseudomonas fluorescens SBW25 :: gfp/lux, Arthrobacter chlorophenolicus A6G, and Paenibacillus peoriae BD62 (pnf8)) to vital and nonvital extraradical hyphae of the arbuscular mycorrhizal fungi Glomus sp. MUCL 43205 and Glomus intraradices MUCL 43194 was examined. Arthrobacter chlorophenolicus did not attach to hyphae, whereas the other bacterial strains did to a varying degree. Only P. brasilensis showed greater attachment to vital hyphae than nonvital hyphae of both Glomus species tested. Pseudomonas fluorescens showed a higher attachment to vital compared with nonvital Glomus sp. MUCL 43205 hyphae, whereas this relationship was opposite for attachment to G. intraradices. Both B. cereus and P. peoriae showed higher attachment to nonvital hyphae. This study provides novel evidence that under laboratory conditions soil bacteria differ in their ability to colonize vital and nonvital hyphae and that this can also be influenced by the arbuscular mycorrhizal fungal species involved. The significance of bacterial attachment to mycorrhizal fungal extraradical hyphae is discussed. PMID:16451176

Clinical signs are evolved by clinicians through their careful clinical examination. Medical professionals are generally familiar with these signs because of the emphasis given to them by the teaching faculty while they were students. Some of these signs are eponymously named after the clinicians giving credit to their observation. Eponymous signs in vesiculobullous diseases such as Nikolsky sign and Asboe Hansen sign (Bulla spread sign) are well known and were described during the 19th and 20th century, respectively. Cerebriform tongue in pemphigus vegetans was described by Premalatha (1981) three decades ago and is well recognized and cited in several text books and articles in leading journals. All these signs are revisited below with an emphasis on cerebriform tongue in pemphigus vegetans which could eponymously be called as Premalatha sign.

Reflexology: its effects on physiological anxiety signs and sedation needs.  

PubMed

To investigate whether reflexology has an effect on the physiological signs of anxiety and level of sedation in patients receiving mechanically ventilated support, a single blinded, randomized controlled design with repeated measures was used in the intensive care unit of a university hospital in Turkey. Patients (n = 60) aged between 18 and 70 years and were hospitalized in the intensive care unit and receiving mechanically ventilated support. Participants were randomized to a control group or an intervention group. The latter received 30 minutes of reflexology therapy on their feet, hands, and ears for 5 days. Subjects had vital signs taken immediately before the intervention and at the 10th, 20th, and 30th minutes of the intervention. In the collection of the data, "American Association of Critical-Care Nurses Sedation Assessment Scale" was used. The reflexology therapy group had a significantly lower heart rate, systolic blood pressure, diastolic blood pressure, and respiratory rate than the control group. A statistically significant difference was found between the averages of the scores that the patients included in the experimental and control groups received from the agitation, anxiety, sleep, and patient-ventilator synchrony subscales of the American Association of Critical-Care Nurses Sedation Assessment Scale. Reflexology can serve as an effective method of decreasing the physiological signs of anxiety and the required level of sedation in patients receiving mechanically ventilated support. Nurses who have appropriate training and certification may include reflexology in routine care to reduce the physiological signs of anxiety of patients receiving mechanical ventilation.

[Neurological signs in aortic dissection].  

PubMed

A substantial number of patients suffering from aortic dissection will show neurological signs. These can dominate the clinical picture and hinder an accurate diagnosis of this life-threatening disease. We present a case of lower extremity pain and a case of transient global amnesia caused by aortic dissection. A third patient suffered from acute cerebral ischemia accompanied by hypotension and back pain, suggestive of aortic dissection. In this third case, aortic dissection was excluded before systemic thrombolytic therapy was administered, for the patient could have suffered disastrous complications caused by this emergency stroke therapy. Clinicians should be aware that a wide range of cerebral, spinal and peripheral neurological signs can be caused by aortic dissection. An unusual combination of symptoms can be a clue for underlying aortic disease. High-risk clinical features are predisposing factors in medical history, typical acute onset back or chest pain, and pulse deficit, blood pressure asymmetry or a new cardiac murmur on physical examination. These features should be explicitly evaluated in patients with an acute neurological deficit. If neurological symptoms and a high-risk clinical feature are present, immediate aortic imaging should be considered since early detection can be life saving. PMID:24330794

PubMed

This study assessed the efficiency with which young and older adults of varying field dependence extract information from traffic signs. It also identified some visual attributes of signs which affect recognition time. Two experiments were conducted. In Exp. 1, digitized signs, embedded in rural and urban backgrounds, were presented on a computer monitor. Subjects indicated on which side a target sign had appeared. Analysis showed that recognition times were dependent on age and field-dependence scores. Also, visual backgrounds and spatial frequency of pictographs affected RTs. In Exp. 2, recognition RT to 2 signs with redesigned pictographs was measured as well as time taken to detect signs. The signs showing reduced spatial frequency were the fastest to recognize, although no effect was noticed during detection. The subjects who showed the worst performance when facing the original signs benefitted the most from the modifications. PMID:8022689

Cooperative Sign Language Tutoring: A Multiagent Approach  

NASA Astrophysics Data System (ADS)

Sign languages can be learned effectively only with frequent feedback from an expert in the field. The expert needs to watch a performed sign, and decide whether the sign has been performed well based on his/her previous knowledge about the sign. The expert's role can be imitated by an automatic system, which uses a training set as its knowledge base to train a classifier that can decide whether the performed sign is correct. However, when the system does not have enough previous knowledge about a given sign, the decision will not be accurate. Accordingly, we propose a multiagent architecture in which agents cooperate with each other to decide on the correct classification of performed signs. We apply different cooperation strategies and test their performances in varying environments. Further, through analysis of the multiagent system, we can discover inherent properties of sign languages, such as the existence of dialects.

The Vital Issues Process, developed by the Sandia National Laboratories Strategic Technologies Department, was utilized by the Health Care Task Force Advisory Group to apply structure to their policy deliberations. By convening three expert panels, an overarching goal for the New Mexico health care system, seven desired outcomes, nine policy options, and 17 action items were developed for the New Mexico health care system. Three broadly stated evaluation criteria were articulated and used to produce relative rankings of the desired outcomes and policy options for preventive care and information systems. Reports summarizing the policy deliberations were submitted for consideration by the Health Care Task Force, a Joint Interim Committee of the New Mexico Legislature, charged with facilitating the development and implementation of a comprehensive health care delivery system for New Mexico. The Task Force reported its findings and recommendations to the Second Session of the 41st New Mexico State Legislature in January 1994.

Associations between VO2max and vitality in older workers: a cross-sectional study  

PubMed Central

Background To prevent early exit from work, it is important to study which factors contribute to healthy ageing. One concept that is assumed to be closely related to, and therefore may influence healthy ageing, is vitality. Vitality consists of both a mental and a physical component, and is characterised by a perceived high energy level, decreased feelings of fatigue, and feeling fit. Since VO2max gives an indication of one's aerobic fitness, which can be improved by increased levels of physical activity, and because feeling fit is one of the main characteristics of vitality, it is hypothesised that VO2max is related to vitality. Therefore, the aim of this study was to investigate the associations between VO2max and vitality. Methods In 427 older workers (aged 45 + years) participating in the Vital@Work study, VO2max was estimated at baseline using the 2-km UKK walk test. Vitality was measured by both the UWES Vitality Scale and the RAND-36 Vitality Scale. Associations were analysed using linear regression analyses. Results The linear regression models, adjusted for age, showed a significant association between VO2max and vitality measured with the RAND-36 Vitality Scale (? = 0.446; 95% CI: 0.220-0.673). There was no significant association between VO2max and vitality measured with the UWES (? = -0.006; 95% CI:-0.017 - 0.006), after adjusting for age, gender and chronic disease status. Conclusions VO2max was associated with a general measure of vitality (measured with the RAND-36 Vitality Scale), but not with occupational health related vitality (measured with the UWES Vitality Scale).

Automatic Detection and Classification of Traffic Signs  

Microsoft Academic Search

This paper proposes algorithms for the automatic detection of traffic signs from photo or video images and their classification to provide a driver alert system. Several examples taken from Portuguese roads are used to demonstrate the effectiveness of the proposed system. Traffic signs are detected by analyzing color information, notably red and blue, contained on the images. The detected signs

An adaptive system for traffic sign recognition  

Microsoft Academic Search

Traffic sign recognition is a primary goal of almost all road environment understanding systems. A vision system for traffic sign recognition was developed by Daimler-Benz Research Center Ulm. The two main modules of the system are detection and verification (recognition). Here regions of possible traffic signs in a color image sequence are first detected before each of them is verified

Road traffic sign detection and classification  

Microsoft Academic Search

A vision-based vehicle guidance system for road vehicles can have three main roles: (1) road detection; (2) obstacle detection; and (3) sign recognition. The first two have been studied for many years and with many good results, but traffic sign recognition is a less-studied field. Traffic signs provide drivers with very valuable information about the road, in order to make

Drivers' immediate responses to traffic signs  

Microsoft Academic Search

Earlier studies have shown that when stopped on the road and requested to report a traffic sign which they just passed, drivers are able to do it correctly more often if the sign is of significance to them. Thus, such a sign is either better detected or better remembered than the less significant ones. In this study, speed changes of

Active aging promotion: results from the vital aging program.  

PubMed

Active aging is one of the terms in the semantic network of aging well, together with others such as successful, productive, competent aging. All allude to the new paradigm in gerontology, whereby aging is considered from a positive perspective. Most authors in the field agree active aging is a multidimensional concept, embracing health, physical and cognitive fitness, positive affect and control, social relationships and engagement. This paper describes Vital Aging, an individual active aging promotion program implemented through three modalities: Life, Multimedia, and e-Learning. The program was developed on the basis of extensive evidence about individual determinants of active aging. The different versions of Vital Aging are described, and four evaluation studies (both formative and summative) are reported. Formative evaluation reflected participants' satisfaction and expected changes; summative evaluations yielded some quite encouraging results using quasi-experimental designs: those who took part in the programs increased their physical exercise, significantly improved their diet, reported better memory, had better emotional balance, and enjoyed more cultural, intellectual, affective, and social activities than they did before the course, thus increasing their social relationships. These results are discussed in the context of the common literature within the field and, also, taking into account the limitations of the evaluations accomplished. PMID:23476644

The Brockenbrough - Braunwald - Morrow Sign  

PubMed Central

Hypertrophic cardiomyopathy is a relatively common genetic disorder and usually asymptomatic. However, approximately 25% of patients develop left ventricular outflow obstruction and can develop angina, syncope, or congestive heart failure. Initiation and titration of beta-blockade usually results in symptomatic improvement. Patients with medically refractory symptoms can see further symptomatic improvement and relief of obstruction with either surgical myectomy or alcohol septal ablation (ASA). Although surgical myectomy has been the gold standard, ASA has been shown in nonrandomized studies and a meta-analysis to be comparable. In patients undergoing ASA without a rest obstruction, the Brokenbrough-Braunwald-Morrow sign can be used to accurately determine the degree of left ventricular outflow tract (LVOT) obstruction prior to, during, and after ASA.

Incidence of post-operative pain following single visit endodontics in vital and non-vital teeth: An in vivo study  

PubMed Central

This clinical study was conducted to compare the post-operative pain following single visit endodontics in vital and non-vital teeth, with and without periapical radiolucency. A total of 60 adult patients requiring root canal therapy in anterior and premolar teeth were selected for this study. Single sitting root canal treatment was carried out and the subjects were recalled after 2 weeks and instructed to fill out a series of self-report questionnaires for responses about pain in the interim after 1 day, 2 day, 3 day, 1 week and 2 weeks. In vital teeth (Group I) 60% of the treated cases had pain, of which 36% had mild pain (non-significant) and 24% had moderate pain (significant). In non-vital teeth without periapical radiolucency (Group II) 64% of cases had pain, of which 48% had mild pain (non-significant) and 16% had moderate pain (significant). In non-vital teeth with periapical radiolucency (Group III) 32% of the cases had pain of which 24% had mild pain (non-significant) and 8% had moderate pain (significant). None of the teeth in any of the groups had severe pain. There was no statistical difference between incidence of pain in vital and non-vital teeth without periapical radiolucency. Non-vital teeth with periapical radiolucency exhibited relatively less pain as compared with non-vital teeth without periapical radiolucency, but the pain continued in a significant percent of teeth even after 2 weeks. Pain incidence dropped significantly within a period of 1 day to 2 weeks in vital teeth and non-vital teeth without periapical radiolucency. There was a tendency for less incidence of significant pain after a single visit root canal treatment in these groups. Results obtained were comparable with those obtained by several investigators.

Decapitation in suicidal hanging--vital reaction patterns.  

PubMed

Complete or incomplete decapitation as a consequence of suicidal hanging is very rare, few cases having been reported in the worldwide literature. Posthanging decapitation is typically related to a drop of several meters. Three cases of complete decapitation and one case of incomplete decapitation by suicidal hanging are reported with particular emphasis on internal findings and vital reaction patterns. Personal, circumstantial, autopsy, and toxicological data were analyzed to define basic characteristics of such extreme injuries. The crucial factor for the state of decapitation itself is the kinetic energy of the falling body, the strength of the human neck tissue, and the diameter and elasticity of the used ligature. Results of our case study suggest Simon's hemorrhage and air embolism as useful autopsy findings in posthanging beheading cases. Simon's hemorrhage was demonstrated in three cases of four. The test for air embolism was positive in all four cases. PMID:23127190

(There are 39 tables total with the remaining 15 to be released later this year.) The tables break down data on births, birth rates, and fertility rates by race, age, state and region, residency status, martial status, place of delivery, prenatal care, and other indicators. Many of the tables include data from previous years for the sake of comparison, reaching back in some cases to 1909. The Technical Appendix offers detailed descriptions of the data included, and all tables are posted individually in .pdf format.

Accurate risk assessments critically depend on the accuracy of the input information about the interaction of ions with materials, electronics and tissues. Due to paucity of the huge amount of needed experimental input data about the interaction of radiation, it is imperative to develop reliable accurate models of nuclear reactions and structures that form the basic input ingredients. State-of-the-art nuclear cross sections models have been developed at the NASA Langley Research center. The vital role and importance of nuclear physics for space missions would be discussed and a few examples would be presented for space missions.

Village registers for vital registration in rural Malawi.  

PubMed

Paper-based village registers were introduced 5 years ago in Malawi as a tool to measure vital statistics of births and deaths at the population level. However, usage, completeness and accuracy of their content have never been formally evaluated. In Traditional Authority Mwambo, Zomba district, Malawi, we assessed 280 of the 325 village registers with respect to (i) characteristics of village headmen who used village registers, (ii) use and content of village registers, and (iii) whether village registers provided accurate information on births and deaths. All village headpersons used registers. There were 185 (66%) registers that were regarded as 95% completed, and according to the registers, there were 115 840 people living in the villages in the catchment area. In 2011, there were 1753 births recorded in village registers, while 6397 births were recorded in health centre registers in the same catchment area. For the same year, 199 deaths were recorded in village registers, giving crude death rates per 100 000 population of 189 for males and 153 for females. These could not be compared with death rates in health centre registers due to poor and inconsistent recording in these registers, but they were compared with death rates obtained from the 2010 Malawi Demographic Health Survey that reported 880 and 840 per 100 000 for males and females, respectively. In conclusion, this study shows that village registers are a potential source for vital statistics. However, considerable inputs are needed to improve accuracy of births and deaths, and there are no functional systems for the collation and analysis of data at the traditional authority level. Innovative ways to address these challenges are discussed, including the use of solar-powered electronic village registers and mobile phones, connected with each other and the health facilities and the District Commissioner's office through the cellular network and wireless coverage.

Habitable worlds with no signs of life.  

PubMed

'Most habitable worlds in the cosmos will have no remotely detectable signs of life' is proposed as a biological hypothesis to be tested in the study of exoplanets. Habitable planets could be discovered elsewhere in the Universe, yet there are many hypothetical scenarios whereby the search for life on them could yield negative results. Scenarios for habitable worlds with no remotely detectable signatures of life include: planets that are habitable, but have no biosphere (Uninhabited Habitable Worlds); planets with life, but lacking any detectable surface signatures of that life (laboratory examples are provided); and planets with life, where the concentrations of atmospheric gases produced or removed by biota are impossible to disentangle from abiotic processes because of the lack of detailed knowledge of planetary conditions (the 'problem of exoplanet thermodynamic uncertainty'). A rejection of the hypothesis would require that the origin of life usually occurs on habitable planets, that spectrally detectable pigments and/or metabolisms that produce unequivocal biosignature gases (e.g. oxygenic photosynthesis) usually evolve and that the organisms that harbour them usually achieve a sufficient biomass to produce biosignatures detectable to alien astronomers.

CT signs of urethral injury.  

PubMed

Computed tomography (CT) is the accepted frontline imaging modality for blunt abdominopelvic trauma. However, urethral injuries are traditionally diagnosed with retrograde urethrography. The CT appearances of urethral injuries and the signs associated with posterior urethral injuries are not well described in the literature. CT scans of patients with pelvic fractures and urethrographically proved posterior urethral injuries were evaluated. CT scans of patients with similar pelvic fractures who did not have urethral injuries were also evaluated. The CT findings of elevation of the prostatic apex, extravasation of urinary tract contrast material above the urogenital diaphragm (UGD), and extravasation of urinary tract contrast material below the UGD were specific for type I, II, and III urethral injuries, respectively. If extraperitoneal bladder rupture is present along with periurethral extravasation of contrast material, the possibility of type IV and IVA urethral injuries should be considered. In addition, the CT findings of distortion or obscuration of the UGD fat plane, hematoma of the ischiocavernosus muscle, distortion or obscuration of the prostatic contour, distortion or obscuration of the bulbocavernosus muscle, and hematoma of the obturator internus muscle were more common in patients with pelvic fractures and associated urethral injuries than in patients with uncomplicated pelvic fractures.

Signed magnification sums for general spherical lenses  

NASA Astrophysics Data System (ADS)

It is well known that the sum of signed magnifications is invariant for mass lens systems. In this paper, we discuss the signed magnification sums of general spherical lens models, including the singular isothermal sphere, the Schwarzschild lens, and the Ellis wormhole, the last of which is an example of the traversable wormholes of the Morris-Thorne class. We show that the signed magnification sums are a very useful tool to distinguish exotic lens objects. For example, we show that one can distinguish the Ellis wormholes from the Schwarzschild lens with the signed magnification sums.

Subjective frequency ratings for 432 ASL signs.  

PubMed

Given the importance of lexical frequency for psycholinguistic research and the lack of comprehensive frequency data for sign languages, we collected subjective estimates of lexical frequency for 432 signs in American Sign Language (ASL). Our participants were 59 deaf signers who first began to acquire ASL at ages ranging from birth to 14 years old and who had a minimum of 10 years of experience. Subjective frequency estimates were made on a scale ranging from 1 = rarely see the sign to 7 = always see the sign. The mean subjective frequency ratings for individual signs did not vary in relation to age of sign language exposure (AoLE), chronological age, or length of ASL experience. Nor did AoLE show significant effects on the response times (RTs) for making the ratings. However, RTs were highly correlated with mean frequency ratings. These results suggest that the distributions of subjective lexical frequencies are consistent across signers with varying AoLEs. The implications for research practice are that subjective frequency ratings from random samples of highly experienced deaf signers can provide a reasonable measure of lexical control in sign language experiments. The Appendix gives the mean and median subjective frequency ratings and the mean and median log(RT) of the ASL signs for the entire sample; the supplemental material gives these measures for the three AoLE groups: native, early, and late.

A vital link: water and vegetation in the Anthropocene  

NASA Astrophysics Data System (ADS)

This paper argues that the interplay of water, carbon and vegetation dynamics is fundamental to some global trends in the current and conceivable future Anthropocene. Supported by simulations with a process-based biosphere model and a literature review, it demonstrates that the connectivity of freshwater and vegetation dynamics is vital for water security, food security and (terrestrial) ecosystem integrity alike. The water limitation of net primary production of both natural and agricultural plants - already pronounced in many regions - is shown to increase in many places under projected climate change, though this development is partially offset by water-saving direct CO2 effects. Natural vegetation can to some degree adapt dynamically to higher water limitation, but agricultural crops require some form of active management to overcome it - among them irrigation, soil conservation and expansion into still uncultivated areas. While crucial to secure food production for a growing world population, such human interventions in water-vegetation systems have, as also shown, repercussions to the water cycle. Indeed, land use changes have been shown to be the second-most important influence on the terrestrial water balance in recent times. Furthermore, climate change regionally increases irrigation demand and decreases freshwater availability, impeding on rainfed and irrigated food production (if not CO2 effects counterbalance this impact - which is unlikely at least in poorly managed systems). Drawing from these exemplary investigations, some research perspectives on how to further improve our quantitative knowledge of human-water-vegetation interactions in the Anthropocene are outlined.

Use of vital wheat gluten in aquaculture feeds  

PubMed Central

Summary In aquaculture, when alternative protein sources of Fish Meal (FM) in diets are investigated, Plant Proteins (PP) can be used. Among them, Vital Wheat Gluten (VWG) is a proteinaceous material obtained from wheat after starch extraction. “It is mainly composed of two types of proteins, gliadins and glutenins, which confer specific visco-elasticity that’s to say ability to form a network providing suitable binding. This will lead to specific technological properties that are notably relevant to extruded feeds”. Besides these properties, VWG is a high-protein ingredient with an interesting amino-acid profile. Whereas it is rather low in lysine, it contains more sulfur amino acids than other PP sources and it is high in glutamine, which is known to improve gut health and modulate immunity. VWG is a protein source with one of the highest nitrogen digestibility due to a lack of protease inhibitor activity and to the lenient process used to make the product. By this way, addition of VWG in diet does not adversely affect growth performance in many fish species, even at a high level, and may secure high PP level diets that can induce health damages.

Planned oil pipeline vital to economy of Kazakhstan  

SciTech Connect

The West Kazakhstan-Kumkol pipeline project is extremely vital to the economy of the Republic of Kazakhstan`s ultimate goal of transporting crude oil produced from the western part of the country eastward to Kumkol, from where it is further transported through existing pipelines to refineries in Chimkent in the south and Pavoldar in the northeast. The two refineries are now mainly supplied with west Siberian crudes imported through a pipeline that approaches Kazakhstan via Omsk. The planned pipeline will allow increased use of local crudes, thereby considerably improving a secure supply for the consumers while also increasing the flexibility of the nation`s overall import/export situation. The importance of this project is stressed by the Kazakh government which has officially classified it as a national priority project. The technical feasibility study of the project was prepared by ILF Consulting Engineers of Germany and Price Waterhouse Financial Consultants is conducting a study to determine the economical viability of the project. The overall cost is estimated at $1.1 billion, with the cost of Phase 1 placed at $600 million.

Evaluation of optical methods of detecting dental pulp vitality  

NASA Astrophysics Data System (ADS)

An attempt to develop an optical probe to assess dental pulp vitality led to the conclusion that it would be difficult to construct an effective optical probe for the middle-aged and older patient who is a common candidate for pulpal assessment. In such patients, vascularity of the gingiva is so much greater than that of the pulp that signals originating in the gingiva overwhelm pulpal effects. This conclusion applies to photoplethysmography, pulse oximetry, and laser Doppler flowmetry, and probably to spectrophotometry as well. The effect of the gingiva was first demonstrated by placing opaque plastic film in the gingival sulcus, which caused attenuation of light passing through molar and bicuspid teeth. More dramatically, the remaining pulsatile signal could be much further attenuated by vasoconstricting the gingiva. An unusually sensitive photoplethysmograph was developed (noise floor, with signal averaging, was near 10 fA), as were a variety of optical probes (including two that approached the tooth below the gingival margin). The tools, methods, and conceptual models that were developed are intended also to be of use to investigators who are developing optical problems for use in younger subjects, in whom such probes appear to be useful.

Identifying vital effects in Halimeda algae with Ca isotopes  

NASA Astrophysics Data System (ADS)

Geochemical records of biogenic carbonates provide some of the most valuable records of the geological past, but are often difficult to interpret without a mechanistic understanding of growth processes. In this experimental study, Halimeda algae are used as a test organism to untangle some of the specific factors that influence their skeletal composition, in particular their Ca-isotope composition. Algae were stimulated to precipitate both calcite and aragonite by growth in artificial Cretaceous seawater. The Ca-isotope fractionation of the algal calcite is much smaller than that for the algal aragonite, similar to the behaviour observed in inorganic precipitates. However, the carbonate from Halimeda is isotopically heavier than inorganic forms, likely due to Rayleigh distillation within the algal intercellular space. In identifying specific vital effects and the magnitude of their influence on Ca-isotope ratios, this study suggests that mineralogy has a first-order control on the Ca-isotope budget of the carbonate sink and the Ca-isotope composition of seawater.

Symptoms and signs in interpreting Gamma-hydroxybutyrate (GHB) intoxication - an explorative study  

PubMed Central

Background Acute poisoning with gamma-hydroxybutyrate (GHB) has been a serious medical and social problem in different parts of the world including Sweden. GHB is a drug of abuse which acts primarily as central nervous system (CNS) depressants. GHB has serious toxicity, although many young users do not recognise GHB as a dangerous drug. The aim of this pilot study was to explore how symptoms with risk of failure in vital functions would be valued among professionals that encounter GHB intoxication in the emergency phase. Methods A web-based survey focusing on the assessment of vital clinical signs for possible GHB intoxication using a numeric scale was carried out during April and May 2011. The participants, n 105, are all professionals who encounter GHB intoxicated in the emergency phase, but have different levels of training in GHB intoxication, mainly Registered Nurses (RNs) in southwest Sweden, employed in pre-hospital or emergency departments at somatic and most psychiatric health care facilities, as well as police officers who in their work come into contact with drug users. Responses in the survey were scored according to risk of GHB intoxication with serious failure of vital functions. The score value was then referred to a so-called evidence based priority (EBP) scale and analysed using descriptive statistics and Fisher's exact test. Results Cardiac arrest, coma, hypoxia, general convulsions, slow respiratory and heart rate and pale skin are symptoms with the highest risk of serious failure in vital physical functions and were predominantly recognised as such. Conclusion Despite the professionals' different levels of training in GHB intoxication, all of them were relatively well aware of and in accordance regarding the most risky symptoms. The interpretation score for the less risky symptoms and signs of GHB intoxication varied depending on their degree of training. The results should be viewed cautiously, as the size of the professional groups and their general knowledge of critical symptoms of GHB poisoning varied.

Signing at the beginning makes ethics salient and decreases dishonest self-reports in comparison to signing at the end  

PubMed Central

Many written forms required by businesses and governments rely on honest reporting. Proof of honest intent is typically provided through signature at the end of, e.g., tax returns or insurance policy forms. Still, people sometimes cheat to advance their financial self-interests—at great costs to society. We test an easy-to-implement method to discourage dishonesty: signing at the beginning rather than at the end of a self-report, thereby reversing the order of the current practice. Using laboratory and field experiments, we find that signing before—rather than after—the opportunity to cheat makes ethics salient when they are needed most and significantly reduces dishonesty.

An Opinion Spreading Model in Signed Networks  

NASA Astrophysics Data System (ADS)

The opinion spreading process can be modeled as the spread of an epidemic through a network, which assumes homogeneous relationships between individuals. However, positive and negative relationships in signed networks play different roles in the opinion spreading process, following the general rule that the same opinion will diffuse through friends, while the opposite opinion will likely emerge out of interactions between enemies. In order to explore opinion spreading behavior in signed networks, we proposed a simple opinion spreading model based on the susceptible-infected-recovered (SIR) epidemic model. Under the assumption of homogeneous mixing, we also analyzed the phase transition of opinion spreading in signed networks and found that critical spreading rates were closely related to the fraction of positive relationships in signed networks. Finally, we confirmed the correctness of our solutions using numerical simulations of the opinion spreading model in signed networks.

A vital link: water and vegetation in the Anthropocene  

NASA Astrophysics Data System (ADS)

This paper argues that the interplay of water, carbon and vegetation dynamics fundamentally links some global trends in the current and conceivable future Anthropocene, such as cropland expansion, freshwater use, and climate change and its impacts. Based on a review of recent literature including geographically explicit simulation studies with the process-based LPJmL global biosphere model, it demonstrates that the connectivity of water and vegetation dynamics is vital for water security, food security and (terrestrial) ecosystem dynamics alike. The water limitation of net primary production of both natural and agricultural plants - already pronounced in many regions - is shown to increase in many places under projected climate change, though this development is partially offset by water-saving direct CO2 effects. Natural vegetation can to some degree adapt dynamically to higher water limitation, but agricultural crops usually require some form of active management to overcome it - among them irrigation, soil conservation and eventually shifts of cropland to areas that are less water-limited due to more favourable climatic conditions. While crucial to secure food production for a growing world population, such human interventions in water-vegetation systems have, as also shown, repercussions on the water cycle. Indeed, land use changes are shown to be the second-most important influence on the terrestrial water balance in recent times. Furthermore, climate change (warming and precipitation changes) will in many regions increase irrigation demand and decrease water availability, impeding rainfed and irrigated food production (if not CO2 effects counterbalance this impact - which is unlikely at least in poorly managed systems). Drawing from these exemplary investigations, some research perspectives on how to further improve our knowledge of human-water-vegetation interactions in the Anthropocene are outlined.

Effects of Varying Rate of Signing on ASL Manual Signs and Nonmanual Markers  

PubMed Central

Spoken languages are characterized by flexible, multivariate prosodic systems. As a natural language, American Sign Language (ASL), and other sign languages (SLs), are also expected to be characterized in the same way. Artificially created signing systems for classroom use, such as signed English, serve as a contrast to natural sign languages. The present article explores the effects of changes in signing rate on signs, pauses, and, unlike previous studies, a variety of nonmanual markers. Rate was a main effect on the duration of signs, the number of pauses and pause duration, the duration of brow raises, the duration of licensed lowered brows, the number and duration of blinks, all of which decreased with increased signing rate. This indicates that signers produced their different signing rates without making dramatic changes in the number of signs, but instead by varying the sign duration, in accordance with previous observations (Grosjean, 1978, 1979). These results can be brought to bear on three different issues: (1) the difference between grammatical nonmanuals and non-grammatical nonmanuals; (2) the fact that nonmanuals in general are not just a modality effect; and (3) the use of some nonmanuals as pragmatically determined as opposed to overt morphophonological markers reflecting the semantic–syntax–pragmatic interfaces.

xdamp Version 3: An IDL{reg_sign}-based data and image manipulation program  

SciTech Connect

The original DAMP (DAta Manipulation Program) was written by Mark Hedemann of Sandia National Laboratories and used the CA-DISSPLA{trademark} (available from Computer Associates International, Inc., Garden City, NY) graphics package as its engine. It was used to plot, modify, and otherwise manipulate the one-dimensional data waveforms (data vs. time) from a wide variety of accelerators. With the waning of CA-DISSPLA and the increasing popularity of Unix{reg_sign}-based workstations, a replacement was needed. This package uses the IDL{reg_sign} software, available from Research Systems Incorporated in Boulder, Colorado, as the engine, and creates a set of widgets to manipulate the data in a manner similar to the original DAMP and earlier versions of xdamp. IDL is currently supported on a wide variety of Unix platforms such as IBM{reg_sign} workstations, Hewlett Packard workstations, SUN{reg_sign} workstations, Microsoft{reg_sign} Windows{trademark} computers, Macintosh{reg_sign} computers and Digital Equipment Corporation VMS{reg_sign} and Alpha{reg_sign} systems. Thus, xdamp is portable across many platforms. The author has verified operation, albeit with some minor IDL bugs, on personal computers using Windows 95 and Windows NT; IBM Unix platforms; and DEC alpha and VMS systems; HP 9000/700 series workstations; and Macintosh computers, both regular and PowerPC{trademark} versions. Version 3 adds the capability to manipulate images to the original xdamp capabilities.

Neurological soft signs in mentally disordered offenders.  

PubMed

The study used the Neurological Evaluation Scale to assess neurological soft signs in 351 offenders and 80 healthy comparison subjects. Offenders were also interviewed using the Structured Clinical Interview for DSM-IV and the Hare Psychopathy Checklist. Neurological signs were significantly increased in offenders compared with healthy subjects. Offenders with repeated misdemeanors had higher rates of neurological signs than those with a single felony. Neurological scores were significantly predicted by lifetime diagnoses of psychotic, anxiety, and substance use disorders. Each diagnostic category was associated with a distinct pattern of neurological abnormalities. PMID:18070845

Microminiature Monitor for Vital Electrolyte and Metabolite Levels of Astronauts  

NASA Technical Reports Server (NTRS)

Ions, such as proton (pH) and potassium, play a crucial role in body fluids to maintain proper basic functioning of cells and tissues. Metabolites, such as glucose, control the energy available to the entire human body in normal as well as stress situations, and before, during, and after meals. These molecules diffuse easily between blood in the capillaries and the interstitial fluid residing between cells and tissues. We have developed and approach to monitoring of critical ions (called electrolytes) and glucose in the interstitial fluid under the human skin. Proton and potassium levels sensed using optode technology that translates the respective ionic concentrations into variable colors of corresponding ionophore/dye/polymeric liquid membranes. Glucose is monitored indirectly, by coupling through immobilized glucose oxidase with local pH that is then detected using a similar color scheme. The monitor consists of a tiny plastic bar, 100-200 microns wide and 1-2 mm long, placed just under the skin, with color changing spots for each analyte as well as blanks. The colors are read and translated into concentration values by a CCD camera. Direct optical coupling between the in vivo sensing bar and the ex vivo detector device requires no power, and thus eliminates the need for wires or optical fibers crossing the skin. The microminiature bar penetrates the skin easily and painlessly, so that astronauts could insert it themselves. The approach is fully compatible with telemetry in space, and thus, in vivo clinical data will be available real time in the Earth based command center once the device is fully developed. The information provided can be used for collecting hitherto unavailable vital data on clinical effects of space travel. Managing clinical emergencies in space with the sensor already in place should also become much more efficient than without a continuous monitor, as is currently the case. Civilian applications may include better glucose control of patients with moderate to severe diabetes: a growing health problem in the US and World-wide.

The Vital@Work Study. The systematic development of a lifestyle intervention to improve older workers' vitality and the design of a randomised controlled trial evaluating this intervention  

PubMed Central

Background A major contributor of early exit from work is a decline in health with increasing age. As healthy lifestyle choices contribute to better health outcomes, an intervention aimed at an improved lifestyle is considered a potentially effective tool to keep older workers healthy and vital, and thereby to prolong labour participation. Methods Using the Intervention Mapping (IM) protocol, a lifestyle intervention was developed based on information obtained from 1) literature, 2) a short lifestyle questionnaire aimed at indentifying the lifestyle behaviours among the target group, and 3) focusgroup (FG) interviews among 36 older workers (aged 45+ years) aimed at identifying: a) key determinants of lifestyle behaviour, b) a definition of vitality, and c) ideas about how vitality can be improved by lifestyle. The main lifestyle problems identified were: insufficient levels of physical activity and insufficient intake of fruit and vegetables. Using information from both literature and FG interviews, vitality consists of a mental and a physical component. The interviewees suggested to improve the mental component of vitality by means of relaxation exercises (e.g. yoga); physical vitality could be improved by aerobic endurance exercise and strength training. The lifestyle intervention (6 months) consists of three visits to a Personal Vitality Coach (PVC) combined with a Vitality Exercise Programme (VEP). The VEP consists of: 1) once a week a guided yoga group session aimed at relaxation exercises, 2) once a week a guided aerobic workout group session aimed at improving aerobic fitness and increasing muscle strength, and 3) older workers will be asked to perform once a week for at least 45 minutes vigorous physical activity without face-to-face instructions (e.g. fitness). Moreover, free fruit will be offered at the group sessions of the VEP. The lifestyle intervention will be evaluated in a RCT among older workers of two major academic hospitals in the Netherlands. At baseline, after 6 and 12 months, measurements (primary: lifestyle and vitality, and secondary: work-engagement and productivity) will take place. Discussion The lifestyle programme is developed specifically tailored to the needs of the older workers and which is aimed at improving their vitality. Trial registration NTR1240

In-vehicle signing functions and systems concepts  

SciTech Connect

This paper describes functional requirements and system concepts for an In-Vehicle Signing (IVS) system, which will bring information from roadway signs, signals, and pavement markings into the vehicle for presentation to the driver. Information filter functions will assure that the only messages displayed are those which are important to the driver and which apply. Display functions will optimize the presentation of the message to ambient conditions, driver preferences, the number of simultaneous messages, and the urgency of the message. Timing functions will display a sign as soon as it is needed, for the entire time that it applies, and only while it applies. IVS is one of the core components of an integrated In-Vehicle Information System, which will manage and fuse all driving-related information. Two different IVS system concepts have been investigated: one based on a map database, the other on beacon technology. This work is being conducted by the Oak Ridge National Laboratory for the US Federal Highway Administration as part of the Intelligent Transportation System Program.

Neurological soft signs in mainstream pupils  

PubMed Central

AIMS—(1) To examine the relation between neurological soft signs and measures of cognition, coordination, and behaviour in mainstream schoolchildren. (2) To determine whether high soft sign scores may predict children with significant problems in other areas.?METHODS—A total of 169 children aged between 8 and 13 years from mainstream schools were assessed. They form part of a larger study into the outcome of meningococcal disease in childhood. Half had previous meningococcal disease and half were controls. Assessment involved measurement of six soft signs followed by assessment of motor skills (movement ABC), cognitive function (WISC-III), and behaviour (Conners' Rating Scales).?RESULTS—Children having an age corrected soft sign score above the 90th centile were considered to have an excess of soft signs. When compared to the other children they had significantly worse scores on the other three measures. Median movement ABC score was 15.3v 7. Mean total IQ scores were lower by 10.3 points. Median behaviour scores were significantly higher on both parental and teacher questionnaires. A soft sign score above the 90th centile had a sensitivity of 38% for detecting cognitive impairment, 42% for detecting coordination problems, and 25% for detecting possible attention deficit hyperactivity disorder.?CONCLUSION—In this group of children higher scores on the soft sign battery were related to significantly worse performance on measures of cognition, coordination, and behaviour. However, although soft sign assessment may be of interest it cannot accurately predict which children are likely to have impairment in other areas.??

Effect of caffeine on motility and vitality of sperm and in vitro fertilization of outbreed mouse in T6 and M16 media  

PubMed Central

Background: Caffeine increases the CAMP production that stimulates spermatozoa movement. Caffeine is also used for induction of in vitro acrosome reaction in mammalian spermatozoa, an important step in achieving fertilization. Objective: The aim of this study was to assess the effect of caffeine on sperm's motility, vitality and laboratory fertilization rates in mouse in two T6 and M16 media. Materials and Methods: Epididymal mouse sperms were collected and treated by caffine in T6 and M16 media and their motility and vitality rates were evaluated. The pretreated sperms were added to oocytes in T6 and M16 media with and without caffeine and fertilization rates were recorded after 24 hours incubation. Results: Sperm's motility (81.7±1.67%) and vitality (88.7±1.33%) rates and percentage of fertilized oocytes (67.52±8.16%) in T6 medium plus caffeine compare to control group have increased and shown significant differences at p?0.01. While the percentages of these parameters in M16 medium supplemented with caffeine were 68.3±6.01%, 78±6.11%, and 42.6±12.96 respectively and in comparison to control group (M16 without caffeine) have not shown significant differences. Conclusion: Addition of caffeine to T6 medium promotes the sperm's motility and vitality and enhances fertilization and early in vitro development of mouse embryos.

The "eye of the tiger" sign in pure akinesia with gait freezing.  

PubMed

The "eye of the tiger" is a neuroradiologic sign due to iron deposition in the globus pallidus: it appears as diffuse low signal intensity with a central area of high signal intensity confined to the globus pallidus. The "eye of the tiger" sign has been associated with neurodegeneration with brain iron accumulation type 1 (NBIA1), a condition caused by mutations in the gene encoding pantothenate kinase 2 (PANK2). However, the specificity of this neuroradiologic sign has been already challenged and it has been described in other neurodegenerative diseases. Here, we report the first case of a patient suffering from pure akinesia with gait freezing with the "eye of the tiger" sign in T2-weighted MRI sequences. All clinical, laboratory and radiologic data excluded other diagnosis and genetic testing excluded PANK2 mutations suggesting that the "eye of the tiger" is not specific for NBIA1 and may also occur in other movement disorders.

Pallor as a clinical sign of severe anaemia in children: an investigation in the Gambia.  

PubMed

Anaemia associated with malaria is a major public health problem in African countries. Since most primary health facilities have to rely on physical signs and not laboratory tests to detect anaemic patients who need referral for blood transfusion, we have assessed the reliability of simple clinical signs to predict severe anaemia. A trained field assistant examined 368 children admitted to a tertiary care hospital, assessing the pallor of their eyelids (conjunctiva), palms and nailbeds, counting the respiratory rate, and looking for signs of respiratory distress. After the children's admission, their packed cell volume (PCV) was measured, and the need for transfusion and the outcomes were noted. A second observer examined 173 of these children so that interobserver variability in the detection of clinical signs could be assessed. A total of 27% of the 368 children had a PCV of < 15%. In a multiple regression analysis, definite pallor of the conjunctiva, definite pallor of the palms, and a "sick" appearance of the child were identified as independent significant predictors of a PCV of < 15%. The best predictor was a combination of definite pallor of the conjunctiva and pallor of the palms, with a sensitivity of 80% and a specificity of 85%. Inclusion of signs of respiratory distress did not improve the prediction. Pallor was a reproducible sign (weighted kappa statistic for the comparison between two observers: kappa = 0.6 for conjunctival pallor). We conclude that pallor can be used as a sign for referring children who may require blood transfusion. PMID:9529724

P02.02. Quality Improvement Study Suggesting the Value of Point-of-Care Documentation of Quality of Life Vital Signs in an Academic Integrative Health Center  

PubMed Central

Focus Area: Supporting Behavioral Change Rigorous quality improvement and outcome reporting within interdisciplinary academic integrative health centers (IHCs) is a realm requiring significant focus in an era of skyrocketing healthcare costs, especially in management of complex chronic illness. In one southeastern US academic IHC seeing primarily (>80%) patients with chronic pain, treatment modalities include yoga, physical therapy (PT), cognitive-based therapy (CBT), acupuncture, and group therapy. A random sample of returning patients at this IHC completed a paper survey querying the following: treatment length and modalities used as a patient at this IHC; current pain, fatigue, and anxiety levels (0–10); change in pain, fatigue, anxiety, and quality of life (?5, “much worse,” to 5, “much better”) since first visit to this IHC. Seventy-seven responses were collected. Mean and median scores were calculated for current pain (m=3.9, SD=2.6, M=4), fatigue (m=4.7, SD=3.0, M=4), anxiety (m=3.5, SD=2.7, M=3), as well as changes in QOL (m=2.8, SD=1.7, M=3), pain (m=2.4, SD=1.9, M=3), anxiety (m=2.4, SD=1.7, M=3), and fatigue (m=1.8, SD=1.7, M=3). Increasing time following treatment was associated with improved QOL (P=.045, r=0.232) as was an increasing number of services utilized (P=.021, r=0.263). Associated with these QOL changes were improved pain (P<.01, r=0.561), fatigue (P<.01, r=0.604), and anxiety (P<0.01, r=0.495) while more severe current pain (P=.002, r=?.347) and fatigue (P=.015, r=?0.277) upon survey completion inversely predicted QOL change. A two-tailed t-test revealed that patients finding PT useful reported improved QOL (P=.008), anxiety (P=.008), fatigue (P=.006), and pain (P=.003) compared to those not. Patients reporting acupuncture useful enjoyed lower anxiety (P=.016) and improved pain (P=.037) while those finding yoga useful reported improved anxiety (P=.005). Together, these data suggest the potential value of implementing a more robust, EMR-based, and consistent evaluation of different treatment modalities and QOL improvement housed within this interdisciplinary academic IHC for quality improvement of personalized, internally coordinated care.

Online screening for distress, the 6th vital sign, in newly diagnosed oncology outpatients: randomised controlled trial of computerised vs personalised triage  

PubMed Central

Background: This randomised controlled trial examined the impact of screening for distress followed by two different triage methods on clinically relevant outcomes over a 12-month period. Methods: Newly diagnosed patients attending a large tertiary cancer centre were randomised to one of the two conditions: (1) screening with computerised triage or (2) screening with personalised triage, both following standardised clinical triage algorithms. Patients completed the Distress Thermometer, Pain and Fatigue Thermometers, the Psychological Screen for Cancer (PSSCAN) Part C and questions on resource utilisation at baseline, 3, 6 and 12 months. Results: In all, 3133 patients provided baseline data (67% of new patients); with 1709 (54.5%) retained at 12 months (15.4% deceased). Mixed effects models revealed that both groups experienced significant decreases in distress, anxiety, depression, pain and fatigue over time. People receiving personalised triage and people reporting higher symptom burden were more likely to access services, which was subsequently related to greater decreases in distress, anxiety and depression. Women may benefit more from personalised triage, whereas men may benefit more from a computerised triage model. Conclusion: Screening for distress is a viable intervention that has the potential to decrease symptom burden up to 12?months post diagnosis. The best model of screening may be to incorporate personalised triage for patients indicating high levels of depression and anxiety while providing computerised triage for others.

Screening for distress, the 6th vital sign: common problems in cancer outpatients over one year in usual care: associations with marital status, sex, and age  

PubMed Central

Background Very few studies examine the longitudinal prevalence of problems and the awareness or use of clinical programs by patients who report these problems. Of the studies that examine age, gender and marital status as predictors of a range of patient outcomes, none examines the interactions between these demographic variables. This study examined the typical trajectory of common practical and psychosocial problems endorsed over 12 months in a usual-care sample of cancer outpatients. Specifically, we examined whether marital status, sex, age, and their interactions predicted these trajectories. We did not actively triage or refer patients in this study in order to examine the natural course of problem reports. Methods Patients completed baseline screening (N?=?1196 of 1707 approached) and the sample included more men (N?=?696) than women (N?=?498), average age 61.1 years. The most common diagnoses were gastrointestinal (27.1%), prostate (19.2%), skin (11.1%) and gynecological (9.2%). Among other measures, patients completed a Common Problem Checklist and Psychosocial Resources Use questions at baseline, 3, 6, and 12 months using paper and pencil surveys. Results Results indicated that patients reported psychosocial problems more often than practical and both decreased significantly over time. Younger single patients reported more practical problems than those in committed relationships. Younger patients and women of all ages reported more psychosocial problems. Among a number of interesting interactions, for practical problems, single older patients improved more; whereas among married people, younger patients improved more. For psychosocial problems we found that older female patients improved more than younger females, but among males, it was younger patients who improved more. Young single men and women reported the most past-and future-use of services. Conclusions Younger women are particularly vulnerable to experiencing practical and psychosocial problems when diagnosed with cancer, but being married protects these younger women. Marriage appeared to buffer reports of both practical and psychosocial problems, and led to less awareness and use of services. Unexpectedly, young men reported the highest use of psychosocial services. This study informs clinical program development with information on these risk groups.

From Atoms to Animals: The Vital Force in Biology  

SciTech Connect

Perhaps the most significant event in intellectual history has occurred over the past several decades, a convergence of the sciences, a blurring of the distinctions between disciplines, from physics to chemistry to biology. Fundamental questions about human existence have been answered in chemical terms. What brings matter to life? What are our origins? What is the basis of cognitive activity? These and related questions have been a fertile area for philosophy and nonscientific analysis. The long history of such alternative approaches persists to this day. Life chemistry is explained by protein catalysts, in their simplest form known as enzymes, and in their full complexity, referred to as molecular machines. An example of great significance is the so-called transcription machinery, which reads out the genetic code, to direct the formation and function of all living things. The atomic structure of the transcription machinery was determined at Stanford, with the use of intense X-ray beams and facilities at the Stanford Synchrotron Radiation Laboratory at SLAC. The result is an image of this complex machinery in action, bringing genetic information to life.

A Sign Language Screen Reader for Deaf  

NASA Astrophysics Data System (ADS)

Screen reader technology has appeared first to allow blind and people with reading difficulties to use computer and to access to the digital information. Until now, this technology is exploited mainly to help blind community. During our work with deaf people, we noticed that a screen reader can facilitate the manipulation of computers and the reading of textual information. In this paper, we propose a novel screen reader dedicated to deaf. The output of the reader is a visual translation of the text to sign language. The screen reader is composed by two essential modules: the first one is designed to capture the activities of users (mouse and keyboard events). For this purpose, we adopted Microsoft MSAA application programming interfaces. The second module, which is in classical screen readers a text to speech engine (TTS), is replaced by a novel text to sign (TTSign) engine. This module converts text into sign language animation based on avatar technology.

In this paper we outline the history, accompanying pathologies and the differentiation and probable pathophysiology of DTS. We also discuss whether we can predict tumoral involvement of the dural tail before surgery and whether the dural tail adjacent to a tumor should be resected.

Safety belts are the most important safety system in motor vehicles and when worn intend to prevent serious injuries. However, in unusual circumstances (high velocity motor vehicle collisions) these safety measures (seat belts) can be the source and cause of serious injuries. The seat belt syndrome was first described as early by Garrett and Braunste in but the term “seat belt sign” was discussed by Doersch and Dozier. Medical personnel's involved in emergency care of trauma patients should be aware of seat belt sign and there should a higher index of suspicion to rule out underlying organ injuries.

Acquisition of signs from American sign language in hearing individuals following left hemisphere damage and aphasia.  

PubMed

Three severely aphasic hearing patients with no prior knowledge of sign language were able to acquire competency in aspects of American Sign Language (ASL) lexicon and finger spelling, in contrast to a near complete inability to speak the English counterparts of these visuo-gestural signs. Two patients with damage in left postero-lateral temporal and inferior parietal cortices mastered production and comprehension of single signs and short meaningful sign sequences, but the one patient with damage to virtually all left temporal cortices was less accurate in single sign processing and was unable to produce sequences of signs at all. These findings suggest that conceptual knowledge is represented independently of the auditory-vocal records for the corresponding lexical entries, and that left anterior temporal cortices outside of traditional "language areas" are part of the neural network which supports the linkage between conceptual knowledge and linguistic signs, especially as they are used in the sequenced activations required for production or comprehension of meaningful sentences.

Pemberton's Sign: Explained Nearly 70 Years Later.  

PubMed

Context: Pemberton's sign is used to evaluate venous obstruction in patients with goiters. The sign is positive when bilateral arm elevation causes facial plethora. It has been attributed to a "cork effect" resulting from the thyroid obstructing the thoracic inlet, thereby increasing pressure on the venous system. According to some, the "cork effect" is caused by the thyroid descending into the thoracic inlet during arm elevation. According to others, the obstruction is due to elevation of the thoracic inlet against the thyroid. Objective: We studied a 36-year-old man with a positive Pemberton's sign secondary to a goiter extending to the substernal region. Design and Intervention: Clinical, biochemical, and radiological assessments were done. Magnetic resonance angiography of the neck was performed while the patient's arms were elevated and at his sides. After the imaging studies were completed, the patient underwent thyroidectomy. Results: Magnetic resonance angiography demonstrated that there was no craniocaudal movement of the goiter relative to the thoracic inlet. However, the lateral aspect of the clavicle moved medially and inferiorly, obstructing the right external jugular vein and subclavian vein confluence. Conclusions: In the present case, we demonstrated that when eliciting Pemberton's sign, facial plethora and venous engorgement were due to the clavicles moving and compressing venous vasculature against the enlarged thyroid and not to a "cork effect." Rather, the clavicular motion observed during arm elevation could be compared to the movement of a "nutcracker" compressing major venous structures within a narrowed thoracic inlet against a relatively fixed and enlarged thyroid.

A new biomedical device for in vivo multiparametric evaluation of tissue vitality in critical care medicine  

NASA Astrophysics Data System (ADS)

Real time Monitoring of mitochondrial function in vivo is a significant factor in the understanding of tissue vitality. Nevertheless a single parameter monitoring device is not appropriate and effective in clinical diagnosis of tissue vitality. Therefore we have developed a multi-parametric monitoring system that monitors, in addition to mitochondrial NADH redox state, tissue microcirculatory blood flow, tissue total back-scattered light as an indication of blood volume and blood oxygenation (Hb02). In the present communication a new device named "CritiView" is described. This device was developed in order to enable real time monitoring of the four parameters from various organs in the body. The main medical application of the CritiView is in critical care medicine of patients hospitalized in the Intensive Care Units (ICUs) and intraoperatively in operating rooms. The physiological basis for our clinical monitoring approach is based on the well known response to the development of body emergency situation, such as shock or trauma. Under such conditions a process of blood flow redistribution will give preference to vital organs (Brain, Heart) neglecting less vital organs (Skin, G-I tract or the urinary system). Under such condition the brain will by hyperperfused and O2 supply will increase to provide the need of the activated mitochondria. The non-vital organs will be hypoperfused and mitochondial function will be inhibited leading to energy failure. This differentiation between the two types of organs could be used for the early detection of body deterioration by monitoring of the non-vital organ vitality. A fiber optic sensor was embedded in a Foley catheter, enabling the monitoring of Urethral wall vitality, to serve as an early warning signal of body deterioration.

Toward a Phonetic Representation of Signs, I: Sequentiality and Contrast  

ERIC Educational Resources Information Center

In this paper we examine the theory of the structure of signs that grew from Stokoe's (1965) proposals. We begin by examining argument for the structural simultaneity of signs by examining claims about how signs contrast and how cheremes function. Historically, such discussions have involved three claims: (1) that signs are composed of a single…

Traffic sign recognition by color segmentation and neural network  

NASA Astrophysics Data System (ADS)

An algorithm is proposed for traffic sign detection and identification based on color filtering, color segmentation and neural networks. Traffic signs in Thailand are classified by color into four types: namely, prohibitory signs (red or blue), general warning signs (yellow) and construction area warning signs (amber). A color filtering method is first used to detect traffic signs and classify them by type. Then color segmentation methods adapted for each color type are used to extract inner features, e.g., arrows, bars etc. Finally, neural networks trained to recognize signs in each color type are used to identify any given traffic sign. Experiments show that the algorithm can improve the accuracy of traffic sign detection and recognition for the traffic signs used in Thailand.

Mental representations of obligatory and prohibitory traffic signs.  

PubMed

Every traffic sign conveys a single proposition about traffic conditions. Drivers must integrate this proposition with their goals and other known facts to decide on an appropriate action in what amounts to a deduction task. For example, imagine that you are driving a car and you want to turn right at an intersection but there is a 'no right turn' sign. You have to assess the options and make a decision (reach a conclusion). Theoretical accounts from research about reasoning can be applied to how we understand traffic signs and make inferences from them. This study includes two experiments that analysed how people decide whether a situation is allowed or not, taking into account the information provided by one sign--obligatory or prohibitory--or two signs--two obligatory or two prohibitory signs. The number of signs, that is, the complexity of the driving scene, was a key factor in this study. The two experiments differ in the presentation format of the two-sign experimental condition. In the first experiment, the signs were presented as two isolated signs. In the second experiment, the two signs were embedded in one. Equivalent results were found whether two isolated signs or two embedded signs were shown. When an obligatory sign was used at the junction, faster responses were obtained for allowed manoeuvres than for those not allowed. When a prohibitory sign was used, the results were the opposite. However, the advantage of prohibitory signs in the not-allowed situation was not replicated when people had to collect information from two prohibitory signs. Results showed that people integrate two obligatory sign messages--informing where one can go--more easily than two prohibitory sign messages--informing where not to go. Therefore, it could be said that each traffic sign elicits an internal mental model elaboration in which forbidden actions are explicitly labelled by means of attached "mental footnotes" indicating the epistemic status of "prohibitory information."
