The Influence of Self-Efficacy on Physical Activity in Individuals With End-Stage Renal DiseaseKack, Shannon 27 April 2010 (has links)
Background and Purpose: Physical activity is significantly lower in the end-stage renal disease (ESRD) population compared with age-matched sedentary controls. Self-efficacy is a significant contributing factor to exercise behaviour in the healthy and various chronic disease populations; however, little information is available on self-efficacy and exercise in the ESRD population. The purpose of this study was to examine the relationship between self-efficacy and physical activity levels in individuals with ESRD and to determine factors which may contribute to this relationship.
Participants: Patients (127 hemodialysis and 5 peritoneal dialysis) were recruited from the Kingston General Hospital renal units.
Methods: Self-efficacy was measured using the Exercise Self-Efficacy Scale (ESES) and the Chronic Disease Self-Efficacy Scale (CDSES). Physical activity was measured using the Human Activity Profile (HAP). Responses on the HAP resulted in 2 scores: the maximum activity score (MAS) and the adjusted activity score (AAS). Contributing factors, such as age, co-morbidities, length on dialysis (vintage), medications, dialysis efficacy (Kt/V), albumin, prealbumin, total protein, protein catabolic rate (PCR) and hemoglobin (HgB) were collected from patient records.
Results: The average MAS and AAS scores were 62.5±15.6 and 49.1± 21.0 (SD), respectively, which are substantively lower than those in the healthy population. Serum albumin was the sole contributing factor to physical activity such that AAS in those with lower levels of albumin (24-30g/L, 31-34 g/L) was less than those with higher levels of albumin (p<0.05). Both MAS and AAS were significantly lower in those with diabetes (n=66) compared to those without (n=66), as was the difference between MAS and AAS. Age and self-efficacy explained 51% of the variance in MAS. Age, self-efficacy and serum albumin level explained 59% of variance in AAS.
Discussion and Conclusion: Individuals on dialysis have lower functional capability within their maximal energy ability at any age and this difference is more pronounced among those with diabetes. Physical activity was substantially influenced by an individual’s self-efficacy, age and serum albumin level. These findings indicate that self-efficacy must be taken into account and used to promote greater participation in physical activity in the ESRD population. / Thesis (Master, Rehabilitation Science) -- Queen's University, 2010-04-27 09:47:12.764

Epidemiological studies of childhood diabetes and important health complications to the diseaseBerhan, Yonas January 2014 (has links)
Background and aims: The overall aim of this thesis was to increase knowledge regarding the occurrence of childhood onset T1D and T2D in Sweden and in relation to that describe and elucidate important aspects on two grave complications to diabetes; end-stage renal disease (ESRD) and mortality. The two first studies included in this thesis aimed to describe and analyze the cumulative incidence of childhood onset T1D in Sweden and to assess the occurrence of undetected T2D in Swedish children. The aim with the third study was to describe the cumulative incidence of ESRD, and to analyze how ESRD risk differs with age at-onset and sex. The aim of the fourth study was to show how parental socioeconomic status (SES) affects all cause mortality in Swedish patients with childhood onset T1D. Study populations: The foundation for the studies on T1D was data from the Swedish Childhood Diabetes Registry (SCDR). When studying ESRD we also included adult onset T1D cases from the Diabetes Incidence Study in Sweden (DISS). The study on T2D was a population-based screening study where BMI was measured in 5528 school-children and hemoglobin A1c was measured in children with overweight according to international age and sex specific BMI cut-offs. To study ESRD and mortality, we linked the SCDR to various nationwide registers containing individual information on SES, mortality and ESRD. Results: The incidence rates of childhood onset T1D has continued to increase in Sweden 1977–2007. Age- and sex-specific incidence rates varied from 21.6 (95% CI 19.4–23.9) during 1978–1980 to 43.9 (95% CI 40.7– 47.3) during 2005–2007. Cumulative incidence by birth-cohorts has shifted to a younger age at-onset over the first 22 years of incidence registration. From the year 2000 there was a significant reverse in this trend (p<0.01). In contrast to the increase of T1D, we found no evidence of undetected T2D among Swedish school children. Despite a relatively high incidence in T1D in Sweden there is low cumulative incidence of ESRD, 3.3% at maximum 30 years of duration. We found difference between the sexes regarding long-term risk of developing ESRD that was dependent on the age at onset of T1D. When analyzing how socioeconomic status affects mortality in different age at death groups, we found that having parents that received income support increased mortality up to three times in those who died after 18 years of age. Conclusion: The incidence of childhood onset T1D continued to increase in Sweden 1978-2007. Between the years 1978-1999 there was a shift to a younger age at-onset, but from the year 2000 there is a change in this shift indicating a possible trend break. The prevalence of T2D among Swedish children up to 12 years of age is probably very low. There is still a low cumulative incidence of T1D associated ESRD in Sweden. The risk of developing ESRD depends on age at-onset of T1D, and there is a clear difference in risk between men and woman. Excess mortality among subjects with childhood onset T1D still exists, and low parental socioeconomic status additionally increased mortality in this group.

The Effects of Acid-Base Parameters, Oxygen and Heparin on the Ability to Detect Changes in the Blood Status of End-Stage Renal Disease Patients Undergoing Hemodialysis Using Whole Blood-Based Optical SpectroscopyAtanya, Monica 18 April 2011 (has links)
Relative changes are detectable in the blood of end-stage renal disease (ESRD) patients during hemodialysis (HD) treatment using optical spectroscopy. However, the potential impacts of several confounding factors that could affect the detection of these changes have not been evaluated. The objectives of this thesis were to: 1) investigate how the variations and/or changes in acid-base and oxygen parameters during HD treatment can affect the optical signature of whole blood of ESRD patients, 2) to investigate the effect of heparin on the optical properties of whole blood and its impact on our method.
Blood samples were drawn from 23 ESRD patients at 5 time points during a 4 hour HD treatment and sent for blood gas and blood spectroscopy analyses. No significant correlations were found between the changes in the blood transmittance spectra and acid-base and oxygen parameters. This indicates that the perturbations in these parameters due to HD procedures do not confound the detection of changes in the blood transmittance spectra of ESRD patients during HD treatment. Additionally, the effect of heparin in modifying the optical properties of whole blood does not confound the detection of changes in the blood of ESRD patients due to HD treatment using whole blood-based optical spectroscopy.
ANOVA revealed significant (P<0.05) measurable changes in the blood transmittance spectra of ESRD patients during HD treatment. Significant spectral differences (P<0.05) were found between ESRD patients. The lack of uniform spectral characteristics across patients is

Dialysis Modality and Health-Related Quality of Life of Persons with End Stage Renal DiseaseJanuary 2011 (has links)
abstract: Health-related quality of life (HR-QOL) is a significant treatment outcome for persons with end-stage renal disease (ESRD); however, little is known about the HR-QOL of Mexican patients with ESRD. This pilot study describes relationships between demographics, sleep disorders, spirituality, mood, folk practices and dialysis modality on the HR-QOL of patients with ESRD residing in Guanajuato, Mexico. Mexican patients receiving continuous ambulatory peritoneal dialysis (CAPD), automated peritoneal dialysis (APD) and hemodialysis (HD) provided information on demographics, clinical health data including body mass index (BMI), and folk health practices. Measures included the Short Form (SF)-36 HR-QOL survey, Sleep Habits Questionnaire, Latin Spirituality Perspective Scale and Hospital Anxiety and Depression Scale. Data were analyzed using SAS software (V9.1). Signifi¬cance level for this pilot study was set at p<0.10. The Quality-Adjusted Life Year method was utilized to examine cost effectiveness for each dialysis modality. Demographics and clinical data showed participants (N=121) to be 59 (SD=13) years, predominantly men (55.4%), married (66.9%), Catholic (92.6%), and not currently working (78.3%). The majority were diabetic (72%) and slightly overweight (BMI M=26.1; SD=5.1). The CAPD group (n=39) demonstrated significantly lower HR-QOL scores compared to the APD (n=42) and HD (n=40) groups. Patients on HD reported higher rates and greater numbers of sleep disorders, including insomnia symptoms, non-restorative and insufficient sleep, and daytime somnolence compared to patients on CAPD and APD. Patients on CAPD reported more anxiety and depression compared to patients on HD and APD. Overall linear regression for HR-QOL found dialysis type, sleep disorders and income to be significant predictors and the model accounted for 31% of the variance. Cost analysis indicated APD as the preferred treatment because it is less costly and results in the best HR-QOL compared to the other treatment modalities. Findings provide the first SF-36 norms for Mexicans with ESRD. Sleep disorders and dialysis type greatly impinge on the HR-QOL of these patients, particularly their mental health. APD was identified as the preferred treatment based on low cost and improved HR-QOL. Results can inform clinical care and health policy for Mexican patients with ESRD. / Dissertation/Thesis / Ph.D. Nursing and Healthcare Innovation 2011

Exercise in haemodialysis patients : impact on markers of inflammationDungey, Maurice January 2015 (has links)
End-stage renal disease patients have a greatly increased risk of cardiovascular disease partly attributed to the elevated levels of systemic inflammation observed in uraemia. One of the key mechanisms underlying inflammation appears to be the immune dysfunction that afflicts almost every aspect of the uraemic immune system. As a consequence patients experience immunosuppression and reduced responsiveness to antigen as well as a simultaneous over-activation leading to a pro-inflammatory environment. In addition, the haemodialysis (HD) treatment itself induces a proinflammatory response but may provide an otherwise opportune time to complete supervised exercise.

Coping with chronic illness: A study with end-stage renal disease patients / Afrontamiento a la enfermedad crónica: estudio en pacientes con insuficiencia renal crónica terminalCassaretto, Mónica, Paredes, Rosario 25 September 2017 (has links)
This study identifies coping styles and strategies used by 40 end-stage renal disease patients over 20 years old who receive treatment in a general hospital in Peru. The instruments applied were a personal sociodemographic questionnaire and the Coping Inventory (Carver, Scheier & Weintraub, 1989). Results showed that emotion focused coping were most frequently used followed by problem focused coping. Planning, acceptance and positive reinterpretation-growth coping strategies were more frequently used by these patients, whereas mental disengagement, suppression of competing activities and behavioral disengagement were the less frequently used coping strategies. Other differences between coping styles and strategies and sociodemographic and medical variables were analyzed. / Esta investigación identifica y describe los principales estilos y estrategias de afrontamiento utilizados por un grupo de pacientes diagnosticados con insuficiencia renal crónica terminal. Participaron 40 pacientes mayores de 20 años, aceptados al programa de transplante de riñón del hospital de seguro social. Se utilizaron una encuesta personal y el Inventario sobre Estilos y Estrategias de Afrontamiento (Carver, Scheier & Weintraub, 1989). Los hallazgos indicaron que los estilos enfocados en la emoción fueron utilizados en mayor frecuencia por los participantes, seguidos por los estilos enfocados en el problema. Entre las estrategias de mayor uso se encontraron la planificación, la aceptación y la reinterpretación positiva-crecimiento, mientras que las estrategias de menor uso fueron desentendimiento conductual, supresión de actividades competentes y desentendimiento cognitivo. Se analizaron las posibles diferencias entre los estilos y estrategias de afrontamiento de acuerdo a las condiciones sociodemográficas y médicas de los participantes.

Assessment of the Care for Children and Young Adults with End-Stage Renal Disease / Evaluation de la prise en charge de l'insuffisance rénale chronique et terminale (IRCT) chez l'enfant et l'adulte jeuneHogan, Julien 17 May 2017 (has links)
La transplantation rénale est reconnue comme le traitement de choix de l’insuffisance rénale terminale chez l’enfant et l’adulte jeune et est associée à une augmentation de la survie et une amélioration de la qualité de vie des patients tout en étant le traitement le plus coût efficace à long terme. Néanmoins, il persiste de nombreuses questions sur la prise en charge des patients avant, pendant et après la transplantation. Le but de cette étude est d’analyser le parcours de soin des enfants présentant une maladie rénale chronique afin de mettre en évidence d’éventuelles disparités dans la prise en charge des patients et de fournir des outils d’aide à la décision afin d’améliorer la prise en charge et le traitement de ces patients.Nous avons utilisé différentes sources de données : le registre français des patients avec traitement de suppléance rénale (registre REIN), le registre européen de traitement de suppléance rénale (ESPN/ERA-EDTA registry) et la base de données médico-administrative des hospitalisations (PMSI).Tout d’abord, nous avons étudié les facteurs médicaux et non-médicaux pouvant induire des inégalités et avons mis en évidence que le sexe féminin est associé à un accès retardé à la transplantation rénale et particulièrement à la transplantation rénale préemptive. Ce désavantage pourrait être en parti expliqué par une progression plus rapide vers l’insuffisance rénale terminale même chez des patients présentant la même maladie. Nous avons également montré que les pratiques des centres de traitements impactaient de façon importante la trajectoire des patients. C’est un déterminant majeur du choix de la modalité de suppléance rénale initiale (hémodialyse ou dialyse péritonéale) et de l’accès à la transplantation rénale essentiellement par le biais de la rapidité d’inscription sur la liste d’attente.Nous nous sommes focalisé sur le sous-groupe des patients les plus jeunes, débutant le traitement de suppléance avant l’âge de 2 ans, dont la prise en charge reste un challenge. Nous avons confirmé d’important progrès dans la prise en charge de ces patients en montrant que seul la présence de comorbidités extra-rénales restait associée à une survie inférieure à celle des autres patients en insuffisance rénale terminale. Concernant la durée de vie des greffons, nous avons montré l’importance du matching de taille entre le donneur et le receveur avec un ratio de taille donneur/receveur optimal entre 1.4 et 1.8. De même, nous retrouvons l’importance du matching HLA classe 2 sur la survie du greffon. Nous allons combiner ces facteurs de risques dans un outils de prédiction pour aider les cliniciens dans le choix des greffons et allons réaliser une validation externe de cet outil sur une autre cohorte.A partir des données d’hospitalisation, nous avons montré que les infections sont la première cause d’hospitalisation post-transplantation devant les rejets et les cancers.Enfin, Du fait de la durée de vie limitée des greffons rénaux et de l’amélioration importante de l’espérance de vie, ces jeunes patients ont la particularité de nécessité fréquemment des transplantations répétées plus ou moins précédées de périodes de dialyse. De ce fait, il convient de considérer la trajectoire globale de ces patients afin de maximiser le temps passé avec un greffon fonctionnel et de minimiser le temps passé en dialyse. Nous avons développé un outil de simulation permettant de tester des modifications de stratégies de prise en charges (ex : augmentation du don vivant ou de la transplantation préemptive, modification des exigences de matching HLA) et leurs effets sur la trajectoire des patients. Cet outil sera développé afin de répondre à des questions plus complexes sur des sous-groupes de patients. / Renal transplantation is nowadays recognized as the treatment of choice for end-stage renal disease in children and young adults. It is associated with improved survival, better quality of life and better long-term cost-effectiveness. However, many questions remain considering the optimal management of the patients before transplantation, during the transplantation process and after transplantation. We aim to analyze the care and treatment received by children with chronic kidney diseases, to detect potential disparities in patients’ management and to provide useful tools to help decision-making and treatment planning.We used several data sources including the French renal replacement therapy (RRT) registry (REIN), the European RRT registry (ESPN/ERA-EDTA) and the French National medico-administrative Hospital Discharge database (PMSI).First, we focused on medical and non-medical factors that may induce disparity and found that besides medical factors, female gender was associated with a delayed access to renal transplantation and especially to preemptive transplantation. This might be partially explained by a faster decline of renal function in girls that remains to be explored. Aside for patients’ characteristics, we found that centers’ practices strongly impact patients’ trajectories. It is a main factor both in the choice of the first modality of RRT (hemodialysis or peritoneal dialysis) and in the access to renal transplantation especially through a faster access to the renal transplant waiting list.Then, we focused on the subgroup of the younger patients starting RRT before 2 years old, whose management is particularly challenging. We confirmed the great improvement in the care of those patients with only extrarenal comorbidities being still associated with a poorer survival. Considering renal transplant survival, we assess the importance of a matching in height between the donor and the recipient with an optimal donor/recipient height ratio between 1.4 and 1.8 and the importance of HLA matching especially in class 2. We aim to combine those risk factors in a prediction tool to help clinicians in their choices and will perform an external validation of this tool on another cohort.Based on the hospital discharge data, we studied post-transplant complications requiring a hospitalization and found that infections are the main cause of hospitalization post-transplant, far more frequent than graft rejection or cancer.Finally, given the longevity of children undergoing kidney transplantation, most pediatric recipients will inevitably develop graft failure, requiring a return to dialysis or a second transplant so that one should consider the complete trajectory of the patients and try to maximize the time spent with a functioning transplant and minimize the time spent on dialysis. We developed a simulation tool allowing us to test modifications of treatment strategies (e.i: increase in transplantation from living-donor kidney or in preemptive transplantation, better HLA-matching at first transplantation) and their effect on patients’ trajectories. This tool will be further implemented to answer more complex questions on specific subgroups of patients.
