Intervention to promote adolescents' communication and engagement in diabetes clinic encounters: A pilot randomized controlled trial

AIM

To conduct a pilot randomized trial of an intervention to improve adolescent question-asking and provider education during paediatric diabetes visits.

METHODS

Adolescents aged 11 to 17 with type 1 diabetes and their parents were enrolled from two urban tertiary paediatric clinics. Adolescents were randomised to the intervention group or control group. Adolescent consultations were audio-recorded, their HbA1c level was recorded, and they completed surveys after three clinic appointments. The intervention group completed a question prompt list and watched a video on a tablet with their parents before meeting their doctor and completed a short evaluation after each visit.

RESULTS

Six consultant endocrinologists and ninety-nine adolescents and their parents participated. The intervention increased adolescents' question asking and provider education in diabetes encounters. Total patient question-asking across the 3 consultations and a higher baseline HbA1c at time one was significantly associated with HbA1c at time three.

CONCLUSIONS

Question prompt lists and an educational video are useful tools to increase adolescents' question-asking and communication between adolescents and their providers.

PRACTICE IMPLICATIONS

Interventions that encourage adolescents' question-asking in healthcare encounters may lead to more meaningful providers-adolescents' communication and tailored education. Interventions to improve professionals' listening, communication and educational skills are also required.

The challenge of patients' unmet palliative care needs in the final stages of chronic illness

BACKGROUND

There is consensus in the literature that the end of life care for patients with chronic illness is suboptimal, but research on the specific needs of this population is limited.

AIM

This study aimed to use a mixed methodology and case study approach to explore the palliative care needs of patients with a non-cancer diagnosis from the perspectives of the patient, their significant other and the clinical team responsible for their care. Patients (n = 18) had a diagnosis of either end-stage heart failure, renal failure or respiratory disease.

METHODS

The Short Form 36 and Hospital and Anxiety and Depression Questionnaire were completed by all patients. Unstructured interviews were (n = 35) were conducted separately with each patient and then their significant other. These were followed by a focus group discussion (n = 18) with the multiprofessional clinical team. Quantitative data were analysed using simple descriptive statistics and simple descriptive statistics. All qualitative data were taped, transcribed and analysed using Colaizzi's approach to qualitative analysis.

FINDINGS

Deteriorating health status was the central theme derived from this analysis. It led to decreased independence, social isolation and family burden. These problems were mitigated by the limited resources at the individual's disposal and the availability of support from hospital and community services. Generally resources and support were perceived as lacking. All participants in this study expressed concerns regarding the patients' future and some patients described feelings of depression or acceptance of the inevitability of imminent death.

CONCLUSION

Patients dying from chronic illness in this study had many concerns and unmet clinical needs. Care teams were frustrated by the lack of resources available to them and admitted they were ill-equipped to provide for the individual's holistic needs. Some clinicians described difficulty in talking openly with the patient and family regarding the palliative nature of their treatment. An earlier and more effective implementation of the palliative care approach is necessary if the needs of patients in the final stages of chronic illness are to be adequately addressed.

Are butter and cheese rich in monounsaturates beneficial in hyperlipidaemic patients?

BACKGROUND

Reduction in intake of dairy products has long been recommended to reduce blood lipids. The value of monounsaturated fatty acids is increasingly recognized.

METHODS

We evaluated the effects of a monounsaturate-rich butter and cheese (B) produced by modifying the bovine diet on blood lipid levels of patients with type IIa hyperlipidaemia. We compared their effects with those of normal butter and cheese (A) and polyunsaturate-rich spread and cheese (C). Using a double cross-over design, we studied 30 patients of mean age 56.4 years (23 men, one woman excluded) over 6-week periods.

RESULTS

Approximately 35.5 g/day butter/cheese were consumed; no changes in serum total cholesterol, triglycerides, low-density lipoprotein, lipoprotein (a) or cholesterol: high-density lipoprotein (HDL) ratio were observed. HDL levels were higher in B(1.31 mmol/l) than in C (1.22 mmol/l; P < 0.05) and similar to those in A (1.28 mmol/l). HDL2 levels were higher in patients fed diet A(0.23 mmol/l) than they were in those fed diet C (0.19 mmol/l; P < 0.05) and similar to those in patients fed diet B (0.20 mmol/l). Serum HDL3 was significantly higher in patients fed diet B (1.11 mmol/l) than in those fed diet C (1.03 mmol/l; P < 0.05) but similar to that in patients fed diet A (1.06 mmol/l).

CONCLUSIONS

Moderate intake of modified dairy products may be of value and deserves further evaluation.

High reductase activity of recombinant NOS2 flavoprotein domain lacking the calmodulin binding regulatory sequence

Nitric oxide synthases (NOSs) represent a special case of the cytochrome P450: cytochrome P450 reductase system in which the two redox partners occur as distinct domains on the same polypeptide chain and are linked by a calmodulin binding regulatory sequence. We expressed the carboxy-terminal, flavoprotein domain (residues 527-1144) of murine NOS2 in E. coli. The UV-visible spectrum of this domain resembles those of other flavoproteins, and the protein catalyses the reduction of ferricytochrome c by NADPH [Vmax = 3.1 +/- .1 mol cytochrome reduced/minute/mmol flavoprotein domain, Km (cytochrome c) = 23 +/- 2 microM, Km (NADPH) 0.30 +/- .06 microM]. The high reductase activity of this NOS2 flavoprotein domain, which lacks a calmodulin binding site, precludes a role for this site in mediating electron transfer within the flavoprotein domain of the intact enzyme. This is in contrast to the case of NOS1 and suggests that electron transfer is regulated differently in the two isoforms.
