Over het gebruik van d-glutaminezuur bij het bacteriologische wateronderzoek

Samenvatting In het d-glutaminezuur werd een chemisch zuivere, relatief goedkoope stof gevonden, die het pepton in de voedingsbodems voor het bacteriologische wateronderzoek lijkt te kunnen vervangen; waarmede de moeilijkhedem uit de wereld zouden zijn, die, vooral bij het colionderzoek, kleven aan het gebruik van peptonen van verschillende herkomst. Hoewel het niet mogelijk bleek, de false presumptive tests geheel te vermijden, wordt toch het voordeel groot genoeg geacht om een proefneming op grooteren schaal in waterleidingbedrijven aan te bevelen.Summary The fact is stressed, that in bacteriological wateranalysis many false presumptive tests occur, where B. coli can not be isolated from strongly fermenting tubes. The view is held, that an improvement may be possible, when substituting peptone by a nitrogen compound, that is easily taken by B. coli and not by the organisms causing the false presumptive test. Therefore d-glutamic acid (as a sodium- or ammoniumsalt) is tried and found to be perfectly suitable to grow B. coli, but equally good to the other organisms. Nevertheless glutamic acid has a distinct advantage on peptone, being a chemically pure and relatively cheap substance, so that difficulties, arising from the use of different brands of commercial peptones, of unknown composition, may be avoided. Investigation of natural waters, using a solution of 1 % lactose, 1 % glutamic acid, 0.1% K₂HPO₄ and 0.05 % MgSO₄ in distilled water, coloured with bromo thymol blue and neutralised with sodium hydroxide to p₄ 7.0, gives the same results as the same liquid, wherein peptone (Witte) substitutes the glutamic acid. Further experience will have to decide on its suitability in large scale practice.     

De impact van het wijkgerichte werken voor de toeleiding naar zorg van oudere migranten

This article studies how older migrants gain access to care through neighbourhood-based forms of working. In the Netherlands, the neighbourhood is increasingly viewed as an ideal place to organize care and social services, close to citizens. To this end, municipalities are developing neighbourhood structures and facilities in which local providers cooperate. In our qualitative research we studied the developments in crafting practices relevant to access to care of older migrants in the city of Nijmegen, the Netherlands. In Nijmegen the new neighbourhood structures are only partly successful in helping older migrants gain access to care. Older migrants visit neighbourhood facilities not for the services these facilities provide, but because of the presence of care professionals who speak the same language, or share the same cultural background as do these older migrants. These caregivers are able to bridge the mental distance between the health care system and the lifeworld of older migrants. Relations also arise outside the neighbourhood structures, for instance at culture-specific day care facilities. To prevent too great a claim on professionals with a migration background, agreements between the city of Nijmegen and local providers to enhance cultural sensitivity should be better monitored.

Kwaliteit van leven van verpleeghuisbewoners met dementie voor,tijdens en na het spelen met de tovertafel

The ‘Active Cues Magic Table’ is a new game concept within nursing home care. It consists of light animations projected on a dining table and responding to movements of the players. The aim of this exploratory, quasi-experimental study was to examine the quality of life of nursing home residents with moderately severe or severe dementia before, during and after playing with this magic table. Quality of life was assessed with the Qualidem and the DS-DAT. Of the 34 nursing home residents included, 62% were female and mean age was 86.5 years (standard deviation 6.2). The Qualidem showed a small to moderate improvement in ‘negative affect’, ‘restless tense behavior’ and ‘positive self-image’ up to the week after playing (p ≤ 0.04). The DS-DAT showed a moderate improvement up to one hour after playing compared to a quarter of an hour before playing (p < 0.001). In conclusion, the quality of life of nursing home residents with moderately severe or severe dementia seems to improve up to the week after playing with the magic table. However, future research is needed to confirm the results of this exploratory study and to examine whether the improvements can truly be ascribed to the magic table.     

De nieuwe redactieadviesraad van het Tijdschrift voor Gerontologie en Geriatrie

It is unknown how often choking occurs in geriatric wards and in nursing homes and what the treatment and outcomes are in regular practice. A questionnaire was sent to Dutch geriatricians (N = 130), nursing home physicians (N = 130), and trainees for these disciplines (N = 215), in order to gain information about the experience, practice and competence of physicians in choking in geriatric and nursing home patients. We also analysed to what extent geriatric and nursing home wards were prepared for accurate handling of choking. The response rate was 30%. More than half of the responders had experienced an episode of food choking at least once in the past five years. The mortality rate in the reported cases was high (30%). The majority of the patients who died of choking had not received the Heimlich-manoeuvre. Physicians who had attended resuscitation training long ago felt as competent to manage a choking episode as physicians that had recently attended resuscitation training. Of all geriatric wards and nursing homes, the majority lacked a guideline on how to handle in acute food choking. Geriatric wards and nursing homes do not seem to be well prepared for acute food choking in several aspects. Despite methodological shortcomings of this study, the results underline the necessity of clarification of the terms used, and development and implementation of guidelines for this important problem.
