Effective peer-to-peer support for young people with end-stage renal disease: a mixed methods evaluation of Camp COOL

Background

The Camp COOL programme aims to help young Dutch people with end-stage renal disease (ESRD) develop self-management skills. Fellow patients already treated in adult care (hereafter referred to as ‘buddies’) organise the day-to-day program, run the camp, counsel the attendees, and also participate in the activities. The attendees are young people who still have to transfer to adult care. This study aimed to explore the effects of this specific form of peer-to-peer support on the self-management of young people (16–25 years) with ESRD who participated in Camp COOL (CC) (hereafter referred to as ‘participants’).

Methods

A mixed methods research design was employed. Semi-structured interviews (n?=?19) with initiators/staff, participants, and healthcare professionals were conducted. These were combined with retrospective and pre-post surveys among participants (n?=?62), and observations during two camp weeks.

Results

Self-reported effects of participants were: increased self-confidence, more disease-related knowledge, feeling capable of being more responsible and open towards others, and daring to stand up for yourself. According to participants, being a buddy or having one positively affected them. Self-efficacy of attendees and independence of buddies increased, while attendees’ sense of social inclusion decreased (measured as domains of health-related quality of life). The buddy role was a pro-active combination of being supervisor, advisor, and leader.

Conclusions

Camp COOL allowed young people to support each other in adjusting to everyday life with ESRD. Participating in the camp positively influenced self-management in this group. Peer-to-peer support through buddies was much appreciated. Support from young adults was not only beneficial for adolescent attendees, but also for young adult buddies. Paediatric nephrologists are encouraged to refer patients to CC and to facilitate such initiatives. Together with nephrologists in adult care, they could take on a role in selecting buddies.

     

Epigenetic regulation of tumor endothelial cell anergy: silencing of intercellular adhesion molecule-1 by histone modifications

Tumors can escape from immunity by repressing leukocyte adhesion molecule expression on tumor endothelial cells and by rendering endothelial cells unresponsive to inflammatory activation. This endothelial cell anergy is induced by angiogenic growth factors and results in reduced leukocyte-vessel wall interactions, thereby attenuating infiltration of leukocytes into the tumor. This report describes a novel mechanism of endothelial cell anergy regulation. We recently reported that DNA methyltransferase (DNMT) and histone deacetylase (HDAC) inhibitors have angiostatic activity. Here, we studied whether epigenetic mechanisms regulate this angiogenesis-mediated escape from immunity. We found that DNMT inhibitors 5-aza-2'-deoxycytidine and zebularine, as well as HDAC inhibitor trichostatin A, reexpressed intercellular adhesion molecule-1 (ICAM-1) on tumor-conditioned endothelial cells in vitro, resulting in restored leukocyte-endothelial cell adhesion. In addition, treatment with DNMT or HDAC inhibitors in vivo also restored ICAM-1 expression on tumor endothelial cells from two different mouse tumor models. Furthermore, leukocyte-vessel wall interactions in mouse tumors were increased by these compounds, as measured by intravital microscopy, resulting in enhanced leukocyte infiltration. We show that ICAM-1 down-regulation in tumor endothelial cells is associated with ICAM-1 promoter histone H3 deacetylation and loss of histone H3 Lys(4) methylation but not with DNA hypermethylation. In conclusion, our data show that ICAM-1 is epigenetically silenced in tumor endothelial cells by promoter histone modifications, which can be overcome by DNMT and HDAC inhibitors, suggesting a new molecular mechanism based on which novel therapeutic approaches for cancer can be pursued.     

Patients'' experience of being critically ill or severely injured and cared for in an intensive care unit in relation to the ICU syndrome. Part I

The intensive care unit (ICU) syndrome is regarded principally as a complex interaction of several contributory factors, all of which can be seen as partly responsible for the development of the syndrome. The purpose of this study was to describe and give a deeper insight into patients' experiences and memory recall, both during and after their stay in the ICU. Nineteen patients who had been respirator treated (ventilated), and had stayed at least 36 hours in the ICU, were interviewed about one week after discharge, and again 4-8 weeks after their discharge from the ICU. Patients' experiences are interpreted and related to previous views held concerning the syndrome, together with an awareness of other important and significant phenomena, i.e. a hermeneutic approach. This study partly confirms the findings of earlier studies concerning the ICU syndrome, but also reveals some new aspects, which have not previously been considered. The patients described themselves as experiencing some sort of state of chaos following the onset of their sickness, injury or accident, which resulted in feelings of extreme instability, vulnerability and fear, often experienced as prolonged inner tension. It was reported that even the most trivial events in circumstances or routines could trigger changes-either an increase or decrease-in patients' feelings of fear or inner tension. The caring relationship was perceived as providing an important degree of security and comfort. Nursing care actions can therefore be seen as vital factors in patients overcoming the accompanying horrific experiences to which they can be subjected. This state of chaotic feeling, and how it is combated and treated, appear to be one critical factor in the development and progression of the ICU syndrome.     

An epidemiologic study of headache among children and adolescents of southern Brazil

To study the epidemiology of pediatric headache, we conducted a cross-sectional study of a randomized and proportional sample of 538 male and female students, 10 to 18 years old. They were in the 5th to 8th grade of the schools of Porto Alegre, RS Brazil. The headache disorders were classified on the basis of clinical interview as well as a physical and neurological examination using the operational diagnostic criteria of the International Headache Society (IHS The following headache prevalences were found: lifetime, 93.2%; last year, 82.9%; last week, 31.4%; last 24 h, 8.9%. Last week and last 24 h headache complaints were twice as prevalent in the female group. During the last year the prevalence of headache disorders was 72.8% for tension-type and 9.9% for migraine headache and was not associated with age distribution. Only the last year and last week prevalences of tension-type headache were significantly higher in the female group. The last year prevalence of headache disorder-proved to be positively associated with sex and age variables. The prevalence of headache disorders was found to be extremely high in this population group, requiring more attention on the part of investigators as a public health problem.
