Nurse-patient interaction after training in integrity promoting care at a long-term ward: analysis of video-recorded morning care sessions.

Morning care is a complex and problematic task for the demented patient, who has problems in understanding and coping with the situation. A training programme of integrity promoting care was given to the staff of a long-term ward and improvements of care were implemented during a 3 month intervention period. To evaluate possible effects, different parameters were used and compared with the data of a control ward. This report describes how caregivers behaved towards demented patients during morning care, before and after the training, and how patients' behaviour changed. The results are based on behaviour samples from 10 patients and 10 caregivers during 99 video-recorded morning care sessions, "double blindly" analysed. The number of coding schemes was 483, each consisting of 93 questions. The most prominent differences observed after the intervention were the increased number of opportunities to take part in decisions and activities given to the patients by the caregivers, more co-operation from patients, and finally an increase in verbal contact initiated both by patients and caregivers. It seems reasonable to suggest that when the environment was made more adequate and the demented patients could cope with it, they could use latent abilities that were not manifest in a less adequate environment.

Disclosure of basic strengths and basic weaknesses in demented patients during morning care, before and after staff training: analysis of video-recordings by means of the Erikson theory of "eight stages of man".

In the field of care for aging persons, it is commonly understood that personality changes occur in dementia patients. It is reported to be a consistent part of the clinical syndrome and to occur early in the disease. The aim of this study was to investigate if strengths and weaknesses, described by E.H. and J.M. Erikson as basic quality in the person, could be interpreted in severely demented patients during a caring activity, and if a difference in these qualities could be seen after staff completed a training program in "integrity promoting care." The morning care of five patients was video-recorded and a phenomenological-hermeneutic analysis of the patient's and staff's interaction was conducted. The findings indicate that the complex qualities of someone's personality are more preserved than could be expected considering the cognitive handicap. It seems, however, that demented patients need a special, supportive environment for their full mental potential to be realized. It is reasonable to assume that, if the staff are given knowledge of how to create a positive climate for the demented patients and the opportunity to implement it, the patients will show a rich pattern of mental reactions in spite of their dementia.

The video-recorded Stroop Color-Word Test as a new model of experimentally-induced anxiety.

1. The use of the Stroop Color-Word Test as a model of experimentally induced anxiety was evaluated. 2. First, the authors examined the influence of trait anxiety and the type of instructions on the anxiety state level. Subjects with high trait anxiety (above 50 on State-Trait Anxiety Scale--STAI) showed a significant increase in anxiety state only with limited time (2 minutes) and error signal (with a ringing bell) procedures. This increase was blocked by diazepam (DZP) 5.0 mg p.o. both on pre- and post-test measures, but it was not changed by placebo administration. 3. The public performance simulation (with a video-camera) was effective to raise the anxiety state on normal volunteers with mean trait anxiety (between 30 and 50 on STAI). This raise was prevented with diazepam 5.0 mg p.o. but it was not prevented with placebo administration. 4. As a whole, these data suggest that the Video-recorded Stroop Color-Word Test is an effective anxiety provoking test, able to detect the effect of standard anxiolytic drug and stressed the importance of trait anxiety level and the instructions on tests that induced anxiety experimentally.

Chewing and swallowing as indices of the stimulation to eat during meals in humans: effects revealed by the edogram method and video recordings.

Patterns of chewing and swallowing were recorded during standardized meals in humans. Cocktail size (3 cm2) open sandwiches were served in one of five different flavors. An oscillographic recording of chewing and swallowing showed that chewing activity varied with the palatability and variety of foods. Chewing time was shorter and fewer chews were observed as palatability increased. Swallowing did not change as a function of stimulus flavor. Pause duration between two successive food pieces became shorter as palatability increased. The effects of sensory factors were most evident at the beginning of meals and decreased until the end of meals. A later study which compared eating parameters in sandwich, semi-solid, and traditional French meals (different courses ingested in succession: appetizer, main course, cheese and dessert), as assessed from video recordings, found that different microstructure parameters responded to palatability manipulation in different meal types. Strength of mastication and prandial drinking might be other important parameters to look at in order to understand the motivation to eat and its fluctuations during the meal.

Analysis of simulated angiographic procedures: part 1--capture and presentation of audio and video recordings.

PURPOSE: To assess different methods of recording angiographic simulations and to determine how such recordings might be used for training and research. MATERIALS AND METHODS: Two commercially available high-fidelity angiography simulations, the Mentice Vascular Interventional Simulation Trainer and the Simbionix AngioMentor, were used for data collection. Video and audio records of simulated procedures were created by different methods, including software-based screen capture, video splitters and converters, and external cameras. Recording parameters were varied, and the recordings were transferred to computer workstations for postprocessing and presentation. RESULTS: The information displayed on the simulators' computer screens could be captured by each method. Although screen-capture software provided the highest resolution, workflow considerations favored a hardware-based solution that duplicated the video signal and recorded the data stream(s) at lower resolutions. Additional video and audio recording devices were used to monitor the angiographer's actions during the simulated procedures. The multiple audio and video files were synchronized and composited with personal computers equipped with commercially available video editing software. Depending on the needs of the intended audience, the resulting files could be distributed and displayed at full or reduced resolutions. CONCLUSIONS: The capture, editing, presentation, and distribution of synchronized multichannel audio and video recordings holds great promise for angiography training and simulation research. To achieve this potential, technical challenges will need to be met, and content will need to be tailored to suit the needs of trainees and researchers.

High-quality video recording and monitoring system for endoscopes.

We have developed a new recording system for endoscope images with the popular mini digital video (mini DV) camera. A special adaptor screws onto the lens top, and either a flexible or rigid endoscope can be attached to the camera. Using this system, we can monitor not only the endoscopic images but also the patient's condition. Satisfactory images can be obtained even with the finest fiberscope. Nevertheless, our new system costs only USD 1,000. Therefore, the system is both cost-effective and useful for the outpatient clinic or casual setting or for house calls for the purpose of patient education.

A low-cost method for simultaneous video-recording of ambulant subject and electroencephalograph: the Quarrier's system.

A system is described by means of which the ambulant subject may be video-filmed over several hours with the electroencephalograph superimposed on the same tape, allowing correlations to be observed in the active state. Our first subjects have been girls with Rett syndrome. Requirements are: one portable video camera/recorder, a conventional e.e.g. machine, the 'Medilog 9000' system for prolonged ambulatory recording (Oxford Medical), a specialized video mixer (videogram ForA FVG600, commercially available) a video timer, a conventional video cassette recorder and a television monitor. The cost is small for a department already equipped to carry out ordinary ambulatory e.e.g. monitoring. The method is safe, well tolerated, simple to use and adaptable. To the best of the authors' knowledge, they are the first to use this system and they believe that it should find wider application when it is desirable to correlate the behaviour of a subject with physiological parameters, on a restricted budget.

Allometry measurements from in situ video recordings can determine the size and swimming speeds of juvenile and adult squid Loligo opalescens (Cephalopoda: Myopsida).

Juvenile and adult Loligo opalescens Berry were video taped in Monterey Bay with the remotely operated vehicle (ROV) Ventana, captured with an otter trawl in Santa Monica Bay, California, and adults were taken from the Monterey Bay fishery. Behavioral observations were made over a 13 h period of video sequences. Allometry measurements were made on 157 squids ranging in size from 12 to 151 mm mantle length (ML). In addition to ML we measured the morphometric characters of fin length (FL), fin width (FW), mantle width (MW), eye diameter (ED), head width (HW), funnel aperture diameter (FA), fourth arm length (AL) and tentacle length (TL). Loligo opalescens changes shape with ontogeny due to negative allometric growth of ED, HW, TL, MW, FA and positive allometric growth of AL, FL and fin area. The allometry measurements were used to determine the size of juvenile squids video-taped in open water. A linear regression can predict dorsal ML in mm from a dimensionless ratio of ML upon ED (r2=0.857, P<0.001). Sizes and velocities of video-taped animals were estimated from 26 video sequences ranging from <1.0 to 8 s. The average velocity for squids ranging from 12-116 mm ML was 0.21 m s(-1) and the maximum velocity was 1.60 m s(-1) (116 mm ML). Allometric measurements can provide scale for 2-dimensional images in order to estimate size, velocity and age of animals.
