Knowledge of staff members of residential care facilities for individuals with intellectual disability on medication administration via enteral feeding tube.

BACKGROUND: Guidelines for the safe administration of drugs through enteral feeding tube (EFT) are an important tool to minimise the risk of errors. This study aimed to investigate knowledge of these guidelines among staff of residential care facilities (RCF) for people with ID. METHOD: Knowledge was assessed using a 13-item self-administered questionnaire. Questions reflected key aspects of guidelines on medication administration via EFT. All staff members that administer medication through EFT in Belgian RCFs were invited to participate (n = 553). RESULTS: Nine out of 10 RCFs participated, and 356 questionnaires were collected. Almost all participants were women (96%), and most (82%) had a non-nursing educational background. Mean self-perceived knowledge of medication administration via EFT was 6.7 (on a 0-10 scale). On average, 5.7 (SD 1.9) out of 13 questions were answered correctly. A nursing degree and previous education on medication administration via EFT were associated with significantly higher scores. Guideline recommendations regarding rinsing of used medicine cups (90% correct answers) and preparation of hard gelatin capsules (89%) were known best. Those regarding the use of protective equipment when crushing toxic substances (4% correct answers), crushing of sustained release and enteric-coated dosage forms (6%), elevation of the patient's backrest (14%) and flushing of the EFT (15%) were known the least. CONCLUSION: This study identified a substantial lack of knowledge of guidelines for drug administration through EFT among staff of RCFs for people with ID. Our findings call for tailored educational programmes in order to increase knowledge on this subject.

Drug administration via enteral feeding tubes in residential care facilities for individuals with intellectual disability: an observational study.

BACKGROUND: The administration of oral medication to patients with an enteral feeding tube (EFT) is challenging. Compliance to guidelines concerning medication administration via EFT has been investigated extensively in the hospital setting. However, studies in residential care facilities (RCFs) for individuals with intellectual disability (ID) are very limited. Therefore, the present study aimed to collect direct observational data on drug administration practices to residents with EFT in multiple RCFs. METHOD: This cross-sectional, observational study was conducted in six Belgian RCFs for individuals with ID. Observations of medication preparation and administration through EFT were carried out in two randomly selected units per participating RCF, on 2 days per unit during all daytime drug rounds, using a direct observation method. Afterwards, the recorded observations were compared with international guidelines on drug preparation and administration through EFT. RESULTS: In total, 862 drug preparations and 268 administrations in 48 residents with EFT were witnessed. Mixing together multiple drugs, not diluting liquid formulations with at least an equal amount of water, not shaking suspensions/emulsions before use, and not selecting the most appropriate dosage form were the most common deviations from medication preparation guideline recommendations. For medication administration, not flushing the EFT with at least 15 mL water was the most common deviation. We also observed high variability in working methods regarding medication preparation and administration via EFT, even between staff members of the same unit. CONCLUSION: This study found that current guidelines concerning medication preparation and administration through EFT are often not followed in Belgian RCFs for individuals with ID. Further research aimed at understanding why current guidelines are not followed seems warranted.

Self and time in individuals with schizophrenia: A motor component?

Phenomenology suggests a disruption in the experience of time in individuals with schizophrenia, related to disorders of the sense of self. Patients themselves relate a fragmentation of their temporal experience and of their sense of self. Temporal expectations help relate the present moment to the future and we have previously shown that temporal expectations are fragile in patients, and relate to disorders of the self. Here, we investigate whether patients' performance is still impaired when the motor response to the expected event can be prepared in advance. In two different experiments participants (41 patients vs. 43 neurotypicals in total) responded to a visual target occurring at a variable interval (or "foreperiod") after an initial warning signal. Moreover, in Experiment 1 we measured the sense of self with the EASE scale. We observed the usual benefit of the passage of time: the longer the waiting period, the better the preparation, and the faster the responses. However, this effect also comprises sequential (surprise) effects, when a target occurs earlier than on the preceding trial. We evaluated the effect of the passage of time, by isolating trials that followed a trial with the same foreperiod. The benefit of long, versus short, foreperiods was still observed in controls but disappeared in patients. The results suggest that the benefit of the passage of time is diminished in patients and relates to self disorders, even when the task allows for motor preparation. The results suggest that a non-verbal impairment sub-tends disorders of the sense of self.

Isometric and isokinetic muscle strength measurements of the lumbar flexors and extensors with BioniX Sim3 Pro in patients with chronic low back pain: A pilot study.

BACKGROUND: The World Health Organization states that low back pain is the leading cause for disability worldwide. Patients with chronic low back pain (CLBP) show important decreases in lumbar strength and can now be assessed by using the new isokinetic dynamometer BioniX Sim3 Pro which offers very detailed measurements. OBJECTIVE: To compare lumbar flexion and extension strength values, as well as extension-flexion ratio (EFR) based on isokinetic velocity and gender, for patients with CLBP on the BioniX Sim3 Pro. METHODS: A retrospective analysis was performed on data from 20 men and 22 women with CLBP. Maximum torque in flexion and extension was measured isometrically and isokinetically. Statistical analysis was performed on these parameters. RESULTS: EFR shows a downward trend with increasing speed of measurement (isometric to isokinetic 30∘/s and isokinetic 30∘/s to isokinetic 90∘/s, respectively): in men from 1.21 to 1.04 (p< 0.001) and from 1.04 to 0.93 (p= 0.207). In women, EFR decreased from 1.41 to 1.13 (p< 0.001) and from 1.13 to 1.00 (p= 0.144). CONCLUSIONS: Patients with CLBP have a decreased strength in lumbar extension and flexion compared to the age-corrected normal values of Bionix Sim3 Pro. With increasing speed of testing protocol, a decrease in EFR is observed in this population.

Lymphatic disorders in rheumatoid arthritis.

Lymphedema is a rare complication of rheumatoid arthritis (RA). Diagnosis is clinical: long-standing, painful swelling of a whole limb in association with RA. Cases described in the literature are predominantly of the upper limbs, sometimes bilateral. Diagnosis can be confirmed by biopsy of lymph nodes, lymphography, or preferably lymphoscintigraphy. The etiology of the edema is unknown. Mechanical obstruction and lymphangitis have been suggested. Pharmacological and surgical treatment of the edema have been disappointing, and treatment of the underlying RA does not improve the lymphedema. Physical treatment of the affected limb, such as massage, manual drainage techniques, light compression bandaging, and exercise, has been moderately effective.

[Cross-over double-blind study using neophylline oral (proxyphylline and diprophylline) in bronchial asthma]. / Gekreuzter Doppeltblindversuch mit Neophyllin oral (Proxyphyllin und Diprophyllin) bei Asthma bronchiale.

In a double-blind crossover trial 16 asthmatic patients were given placebo or 4 or 8 tablets of Neophyllin (each tablet containing 56 mg proxyphylline and 84 mg diprophylline) on two consecutive days. Very slight bronchodilatation independent of the oral dose and plasma level was observed 90 minutes after taking Neophyllin. However, when a betastimulator was inhaled (0.5 mg salbutamol) prior to taking 8 tablets of Neophyllin, surprisingly marked Neophyllin-induced bronchodilatation was observed after 60 and 90 minutes (p less than 0.05 and p less than 0.025). This bronchodilatation was about half that with 4 slow release coated tablets of Neo-Biphyllin (75 mg teophylline in each tablet). When Neophyllin was taken only proxyphylline caused bronchodilatation (no correlation between plasma diprophylline levels and bronchodilatation). The threshold value of plasma proxyphylline was about 13 microgram/ml plasma. Below this level proxyphylline is ineffective (likewise no correlation between plasma proxyphylline levels and bronchodilatation). An oral dose of about 600 mg proxyphylline (in Neophyllin) is needed to reach an effective plasma level within 90 minutes.

The influence of cold and compression on lymph flow at the ankle.

OBJECTIVE: To investigate the effects of cold application with different temperatures on lymph flow in healthy persons and to examine the effects of the combination of cold and compression on lymph vessels. PARTICIPANTS: Thirty-nine healthy persons were included in the study, and each served as his or her own control. INTERVENTION: Water bags (1 degree, 15 degrees, and 32 degrees) with or without 25 mm Hg pressure were applied to the experimental legs for 30 minutes. Cold, pressure, or both were administered by an Aircast-Cryo-cuff (Aircast Europe GMBH, Rosenheim, Germany). MAIN OUTCOME MEASURES: Skin temperature was measured with a TESTO 901 (Testoterm GMBH, Leuven, Belgium) precision thermometer. Lymph flow was recorded continuously using lymphoscintigraphy. MANOVA with repeated measures was used for data analysis. RESULTS: As expected, skin temperature dropped relative to the temperature of the water. The migration of the tracer was comparable in both ankles during the first 30 minutes of the experiment (rest). When the water bag was applied, lymph flow increased significantly (p < 0.01). The application of water of 1 degree C without pressure influenced lymph evacuation significantly differently from the other temperatures. The application of pressure of 25 mm Hg influenced lymph evacuation significantly at 1 degree C and 32 degrees C. CONCLUSION: These results indicate that lymph evacuation at the ankle is influenced significantly when cold water is applied with or without pressure. When pressure is added to the application of water of 32 degrees C, lymph flow will also increase significantly, indicating the importance of pressure in lymph evacuation.

Dehydroepiandrosterone (DHEA) response to i.v. ACTH in patients with chronic fatigue syndrome.

Previous studies have demonstrated concentrating neuroendocrinological disturbances in chronic fatigue syndrome (CFS) patients, concentrating in particular on low cortisol levels and a hypothalamic deficiency. In order to investigate the dynamic response of the adrenal glands, we measured dehydroepiandrosterone (DHEA) in serum after adreno-corticotropic hormone (ACTH) stimulation during 60 minutes in 22 CFS-patients and 14 healthy controls. We found normal basal DHEA levels, but a blunted serum DHEA response curve to i.v. ACTH injection. This observation adds to the large amount of evidence of endocrinological abnormalities in CFS. Relative glucocorticoid deficiency might contribute to the overall clinical picture in CFS, and could explain some of the immunological disturbances observed in this syndrome.
