Adolescents with Type 1 Diabetes: transition between diabetes services

JOURNAL OF CLINICAL NURSING, Issue 6 2006
Kate Visentin MN
Aim., The research aimed to develop a sustainable and coordinated approach to facilitating the transition between diabetes services for adolescents. The objectives were to: (1) involve key diabetes health delivery stakeholders in expressing their concerns and issues about current service delivery and ways to improve same, and (2) reveal from the perspective of the adolescents living with Type 1 Diabetes their experiences surrounding the process of transition. Background., This paper presents research that sought to identify the major concerns and issues that stakeholders had about transition and to reveal the experience of transition for the adolescent with Type 1 Diabetes. Key representatives from seven public diabetes services in Adelaide, South Australia worked collaboratively to answer the objectives of this inquiry. Approach., Interview data were generated and analysed using a response focus framework provided by fourth generation evaluation research. In this study, the focus was on common concerns, claims and issues raised by health care professionals (n = 21) and adolescents (n = 10) aged between 15 and 18 years about transferring from children's to adult diabetes services. Findings., Data revealed education and dietetic advice was reactive rather than proactive and that the paediatric model of care is philosophically and practically different to the adult model of diabetes care. Three phases of transition were identified: preparation, formal transition and evaluation. Our findings indicated that these stages of transition were not being fully implemented in health units. Conclusion., The project findings have set the scene to establish a multidisciplinary working party to work collaboratively across agencies to develop effective transition pathways. Relevance to clinical practice., The role of diabetes nurse educators and dietitians in South Australia is under-used throughout the transition process. Diabetes nurse educators are in an ideal position to prepare, coordinate and evaluate transitional processes. [source]


Consumer participation in mental health services: looking from a consumer perspective

JOURNAL OF PSYCHIATRIC & MENTAL HEALTH NURSING, Issue 4 2003
J. LAMMERS rn bed mba phd
Widespread changes to the structure and delivery of mental health services have effected considerable change in the role of the service user or consumer. The view of consumers of mental health services as passive recipients of care and treatment is gradually undergoing a significant shift, in light of an increasing expectation that consumers be provided with opportunities to become actively involved in all aspects of their care. Consumer participation is now broadly reflected in government policy; however, to date there has been little exploration of the extent to which the policy is being realized in practice. To provide a greater understanding of these experiences and opinions, in-depth interviews were conducted with consumers of mental health services (n = 15). The interview transcripts were analysed through the identification and explication of major themes. The findings reinforce the need to view consumers as heterogenous and respond to individual needs and interests regarding consumer participation. Despite variations in experience there is a clear need to develop mechanisms to support consumer involvement and to influence the attitudes of health professions to become more valuing of a consumer perspective. Nurses are in an ideal position to lead this process. [source]


Clinical use of physical activity measures

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 2 2009
CRNP (Associate Professor), Lorraine M Reiser PhD
Abstract Purpose:, To provide a review of physical activity measures and subjective and objective methods of its measurement. Considerations for the use of these measurements in research and practice will be discussed. Data sources:, The PubMed, CINAHL, and Health and Psychosocial Instruments databases, and the Centers for Disease Control Web site were searched using the search term "Physical Activity Measurement." Conclusions:, Physical activity is a lifestyle factor that is a key focus in chronic disease,related research, prevention, and interventions. Healthy People 2010 set goals of decreasing the prevalence of preventable diseases by encouraging healthier lifestyle patterns. Shifts toward more sedentary lifestyles have resulted in increases in life-limiting disease states, including obesity, diabetes, heart disease, cancer, and osteoporosis. Physical activity measurements have been used widely in research studies but are less commonly used in primary care. Measuring individuals' physical activity levels as part of the health assessment will enhance the provider's ability to engage in health promotion and suggest health protection interventions. The strengths, weaknesses, and potential applications to practice of physical activity measures are summarized in an effort to familiarize nurse practitioners (NPs) with commonly used tools and encourage integration of physical activity assessment into their current practice. Implications for practice:, NPs are in an ideal position to promote health by encouraging appropriate amounts of physical activity. Screening, health promotion, and disease prevention are part of the core competencies of NP practice established by the National Organization of Nurse Practitioner Faculties. Increased knowledge of physical activity measures will enhance the NP's ability to evaluate relevant physical activity research for use in evidence-based practice. Incorporation of simple yet appropriate physical activity measurements into practice will expand the NP's ability to identify and thus address sedentary lifestyles in their clientele. [source]


Nonquenchable Chemical Order,Disorder Phase Transition in Yttrium Oxyfluoride

EUROPEAN JOURNAL OF INORGANIC CHEMISTRY, Issue 1 2005

Abstract A chemical order,disorder polymorphic phase transition in yttrium oxyfluoride (YOF) was studied in situ by X-ray and neutron powder diffraction. The high-temperature form of YOF crystallizes with a cubic Fmm fluorite structure in which the O and F atoms are disordered among the tetrahedrally coordinated sites. The low-temperature form of YOF exhibits rhombohedral Rm symmetry and evolves from the high-temperature form by the phase transition associated with the ordering of the O and F atoms. The transition occurs around 560 C. The superstructure contains layers of [OY4] and [FY4] tetrahedra alternating along the c -axis of the trigonal cell (parallel to the <111> direction of the parent cubic structure). The ordering of the O and F atoms is accompanied by the significant displacements of the Y, O, and F atoms from their ideal positions in the cubic phase. Bond valence sum calculations indicate considerable bond strain for both O and F in the cubic structure; the strain is relieved in the ordered low-temperature phase. The order,disorder transition in YOF is completely reversible and exhibits fast nonquenchable kinetics. ( Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005) [source]


Sickle Cell Disease: Health Promotion and Maintenance and the Role of Primary Care Nurse Practitioners

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 9 2003

Purpose To discuss the role of nurse practitioners (NPs) with regard to early identification of affected individuals, effective monitoring and screening, effective pain management and prophylaxis, and health education for patients with sickle cell disease (SCD). Data Sources Electronic database searches were performed using Medline, Cinahl, and PsycINFO. Data were obtained from medical textbooks, research, and review articles. Conclusions SCD is a chronic inherited disease belonging to a group of conditions called hemo-globinopathies. Individuals with SCD often require close medical care from specialists. Nonetheless, NPs are in ideal positions to facilitate the health promotion and health maintenance necessary to decrease the high rate of morbidity and mortality associated with this disease. Implications for Practice NPs must understand the importance of early identification of affected individuals, effective monitoring and screening, effective pain treatment, and prophylaxis. The unpredictable trajectory of SCD can lead to frustration, fear, helplessness, hopelessness, and emotional distress. Ineffective pain management is a major problem for people with SCD. NPs can overcome this problem by initiating effective and prompt pain management in a nonjudgmental manner. [source]


The architecture of the GroEL,GroES,(ADP)7 chaperonin complex.

ACTA CRYSTALLOGRAPHICA SECTION D, Issue 5 2003

The heptagrammal forms derived in part I [Janner (2003a). Acta Cryst. D59, 783,794] enclose chain segments of symmetry-related monomers in the GroEL,GroES,(ADP)7 chaperonin complex. A chain reaching the boundary of a given form either ends, proceeds to a neighbouring form or has to fold. C, atoms corresponding to these folding points are identified in each of the nine forms of the chaperonin and are approximated by ideal positions having integral coordinates (the indices) with respect to a symmetry-adapted basis. Mutual structural relations between the indexed positions are derived in terms of integral scale-rotations (similar to those that leave the form invariant). The magnesium ions at the binding sites of the nucleotides ADP and ATP are shown to be symmetry-related to these folding points. The change in folding (polymorphism) observed in the cis ring of GroEL arising from binding to GroES is discussed. In particular, the form segmentation is conserved in the polymorphic transition. The geometric and algebraic restrictions imposed on the indexed positions and on their structural relations by the integrality condition are presented in an appendix. [source]
