The development of a quality of life questionnaire for adult patients receiving home parenteral nutrition

Baxter, Janet P. January 2008 (has links)
Home parenteral nutrition (HPN) is an established treatment for the management of patients with severe intestinal failure.  At the moment, it is the treatment of choice for those patients who are unable to eat or drink sufficient food or fluid to maintain nutrition or fluid status. There are no quality of life assessment tools that have been developed and validated specifically for this patient population, previous studies have used generic instruments or techniques not validated in this patient population. A method of objectively assessing the quality of life of patients treated with HPN has been developed – the HPN-QOL questionnaire.  This was designed using qualitative research methods to identify the issues particular to that patient population, thereby eliciting patients’ perspectives on their own quality of life.  The questionnaire was subjected to rigorous psychometric analysis to validate its use in the HPN population. The HPN-QOL has been translated into seven European languages.

No. of bitstreams: 1 Leal_RaquelFranco_M.pdf: 2023236 bytes, checksum: a5b9b6d13e6c045e287305c90fa75f22 (MD5) Previous issue date: 2007 / Resumo: A ileíte do reservatório pós retocolectomia total constitui uma das complicações mais comuns aos doentes com retocolite ulcerativa (RCUI), apresentando pequena freqüência nos doentes com polipose adenomatosa familiar (PAF). Objetivo: Avaliar a atividade inflamatória em mucosa de reservatórios ileais endoscopicamente normais pela expressão de IL-1ß, IL-6, IL-8, TNF-a, da proteína pró-apoptótica p-Bad e a ativação do NF-?B em doentes operados por RCUI e PAF. Casuística e Métodos: Estudou-se 20 doentes submetidos à retocolectomia total com reservatório ileal (RI) em ¿J¿, sendo 10 doentes com RCUI e 10 com PAF. O grupo controle foi constituído por doentes com íleo-colonoscopia normal. As biópsias foram congeladas em nitrogênio líquido e as expressões de TNF-a, IL-1ß, IL-6, IL-8 e p-Bad foram avaliadas por meio de imunoblot de extrato protéico total. A ativação do NF-?B foi determinada por meio de ensaio de imunoprecipitação e imunoblot. Resultados: Expressões de TNF-a, IL-1ß, IL-6, IL-8 e p-Bad foram maiores em RCUI, quando comparados com PAF (p<0.05), enquanto que a ativação de NF-?B foi similar nestes grupos. Os controles apresentaram pequena expressão de TNF-a (p<0.01), comparados com RCUI e PAF. Conclusão: Os doentes com RCUI apresentaram maiores níveis de expressão das citocinas estudadas, mesmo na ausência de sinais clínicos e endoscópicos de ileíte do reservatório. Além disso, neste grupo, houve expressão aumentada de p-Bad. Estes achados podem justificar a maior susceptibilidade dos doentes operados por RCUI a esta complicação e explicar o aumento da apoptose celular, que estaria correlacionada com a atrofia da mucosa em pacientes com ileíte do reservatório / Abstract: Pouchitis after total retocolectomy is the commonest complication in ulcerative colitis UC), while is quite rare in familial adenomatous polyposis (FAP). Objective: To evaluate the nflammatory activity in endoscopically normal ileal pouch mucosa, by determining the expressions of IL-1ß, IL-6, IL-8, TNF-a, a pro-apoptotic protein, p-Bad and the activation of NF-?B in operated patients with UC and FAP. Patients and Methods: Twenty patients submitted to total retocolectomy and J pouch were evaluated, 10 patients with UC and 10 with FAP. The control group consisted of individuals with normal ileo-colonoscopy examination. The collected specimens were snap-frozen in liquid nitrogen and expression of TNF-a, IL-1ß, IL-6, IL-8 and p-Bad were determined by immunoblot of total protein extracts. NF-?B was evaluated by immunoprecipitation and immunoblot. Results: TNF-a, IL-1ß, IL-6, IL-8 and p-Bad expression was increased in patients with UC, when compared with FAP (p<0.05). Otherwise, NF-?B activation was similar in both groups. The control group had little TNF-a expression (p<0.01) when compared with UC and FAP. Conclusion: Patients with UC had increased cytokines levels, even without clinic and endoscopic evidence of pouchitis. Moreover, there was increased p-Bad expression. These findings may suggest a higher susceptibility to this complication in operated patients with UC, and could explain the increased epithelial cell apoptosis, that could be correlated with the mucosa atrophy in patients with pouchitis / Mestrado / Cirurgia / Mestre em Cirurgia

The Effect of inflammatory bowel disease and growth retardation on the self-image of adolescents

Marshall, Helga Adda January 1987 (has links)
This study was undertaken to determine the effect of inflammatory bowel disease (IBD), in general, and one of its manifestations, growth retardation, in particular, on the self-image of adolescents. The conceptualization of adolescent self-image as described by D. Offer (1981) was the basis for the study's framework. The psychological, social, sexual, familial and coping selves, further classified into 11 separate content areas, comprised the adolescent self-image. A descriptive-comparative design was used to describe the self-image of adolescents with IBD and to compare the similarities and differences in self-image among the IBD adolescents with and without growth retardation and their healthy peers. A convenience sampling method was used to obtain 24 IBD subjects between the ages of 12 and 20, eleven of whom had growth retardation. A normative sample of adolescents (N = 1385) was used by permission of D. Offer for purposes of comparison with the IBD subjects. Data were gathered using the Offer Self-image Questionnaire for adolescents. The adolescents with IBD did not differ remarkably from the norm in their perceptions of self although a tendency among the females to have concerns about their body image and sexual maturation was demonstrated. The IBD subgroup without growth retardation reported self-image perceptions that were superior to the norm and the growth retarded subgroup in almost every category. The IBD subgroup with growth retardation reported a disturbed self-image in a number of areas. The males revealed disturbances primarily in body image and secondarily in emotional harmony, and adaptability to stress in the immediate environment, family relations, and sexual maturation. The females revealed self-image disturbances in sexual maturation and body image. The findings of the study suggest that growth retardation in the IBD adolescent may have a negative effect on self-image. The findings may demonstrate a more notable and broader effect of growth retardation on self-image in the males with IBD than in the females. / Applied Science, Faculty of / Nursing, School of / Graduate

Interação da gestação na atividade da doença inflamatória intestinal e sua influência sobre o prognóstico gestacional e na fecundidade / Interaction of pregnancy on inflammatory bowel disease activity and its influence on pregnancy outcome and fecundity

Rodrigues, Leonardo Correa de Oliveira 01 September 2009 (has links)
INTRODUÇÃO: A maioria das mulheres que desenvolvem doença inflamatória intestinal (DII) encontra-se em idade fértil, despertando preocupação dos médicos e mulheres no entendimento desta interação. Avaliamos a influência da DII sobre a fecundidade e gestação e vice- versa. MÉTODOS: Os protocolos de pacientes com doença de Crohn (DC) e retocolite ulcerativa (RC), de 1984 a 2006, em idade fértil, cadastrados no ambulatório de DII, foram revisados. Pacientes foram entrevistados para preenchimento de dados não encontrados nos protocolos. Outros tipos de colites, investigação incompleta, pacientes que não estavam em idade fértil ou sem capacidade cognitiva foram excluídos. Prematuridade, baixo peso ao nascer, anomalias congênitas, natimortalidade, abortamentos, tipos de partos, localização da doença na gestante e uso de medicamentos durante a gestação foram investigados. O método estatístico adotado foi o teste de qui- quadrado e Fisher, com nível de significância de 5%. Nenhum paciente se recusou a participar desta pesquisa. RESULTADOS: 140 gestações em 104 pacientes com DII foram avaliados (RC em 63 gestações e DC em 77). Houve redução da fecundidade após o início dos sintomas relacionados à DII em 41,6%, com influência da doença sobre a opção de não ter filhos em 20,6% (10,3% dos pacientes por medo da doença; 6,5% por orientação médica e 2,2% por más condições clínicas), sem diferenças entre DC e RC. A grande maioria não quis engravidar por já ter filhos, por ser solteira ou estar ter baixa idade (53,3%). A atividade da RC não foi alterada durante a gestação na maioria das pacientes (77,8%; p>0,003). A atividade da doença melhorou durante a gestação mais nas gestantes com DC do que nas com RC (p>0.0007). A incidência de prematuros, baixo peso ao nascer e natimortos foi maior quando todo o cólon estava acometido na RC (p < 0.037). A proporção estimada de prematuros e baixos pesos ao nascer foi de 83,3% [IC 95%: 10,3%; 100,0%]. Não houve diferença estatística quanto à localização da doença e alterações do feto na DC (p > 0,6513). Em 21 gestantes foram administrados aminossalicilatos e em 15, corticosteróides. Em 106 gestações, nenhum medicamento foi administrado. Não houve maior taxa de alterações do concepto quando aminossalicilatos ou corticosteróides foram administrados às gestantes com DII (p > 0,17 and p > 0,1585, respectivamente). CONCLUSÃO: A DII não influenciou diretamente na fecundidade na grande maioria das pacientes. A gestação influenciou positivamente a evolução da DC, independente do uso de medicamentos. A taxa de prematuridade foi maior nas proles de mães com DC. Houve maior taxa de proles com alterações quando todo o cólon estava comprometido na mãe com RC. A DC influenciou o tipo de parto, apenas nos casos de doença perianal extensa associada à doença colônica. / INTRODUCTION: Most of women that develops inflammatory bowel disease (IBD) are in fertile age, concerning doctors and patients to understand this interaction. We evaluated the influence of IBD on fecundity and pregnancy and vice- versa. METHODS: the protocols of patients with Crohns disease (CD) and ulcerative colitis (UC), from 1984 and 2006, in fertile age, followed at the outpatient clinic were reviewed. Patients were interviewed by the research medical doctor, to complete missing data not found in their protocols. Patients with others colitis, incomplete investigation, not in fertile age or without cognitive capacity were excluded from this study. Preterm delivery, low birth weight, congenital anomalies, stillbirth, miscarriages, types of delivery, disease topography in pregnant patients and drug administration during pregnancy were investigated. The statistic method adopted was the chi-square and Fisher test, with significance level of 5%. No patient refused to participate in this study. RESULTS: 140 pregnancies in 104 patients with IBD were evaluated (UC in 63 and CD in 77 pregnancies). : a reduction of 41.6% in fecundity was observed after beginning of symptoms related to IBD, with influence of the disease in 20.6% (10.3% of patients didnt want to have children because of fear related to disease; 6.5% because of medical orientation and 2.2% for poor medical conditions). There was no difference between CD and UC. Most of patients didnt want to become pregnant because they already had children, were underage or alone (53.3%) Most of pregnancies didnt altered clinic conditions in UC patients (77.8% / p=0.003). Clinical conditions improved during pregnancies more in CD patients than UC patients (p=0.0007). The incidence of preterm delivery, low birth weight and stillbirth was higher when the whole colon was affected in UC (p < 0.037). The estimated rate of preterm delivery low birth weight was 83.3%[IC 95%: 10.29%; 100.00%]. There was no statistic difference between the disease topography and the fetus alteration in CD (p > 0.6513). In twentyone and fifteen pregnant women, aminosalicilates and corticosteroids were administered, respectively. In 106 pregnancies, no drugs were administered. There were no higher rates of fetus alteration when aminosalicilates or corticosteroids were administered to mothers with IBD (p > 0.17 and p > 0.1585, respectively). Conclusions: IBD didn´t have any direct influence on fecundity in most of the patients. Pregnancy influenced positively on CD evolution, independently of drug use. The preterm birth rate was higher in children of mothers with CD. There were higher rates of fetus alteration when the whole colon was affected in mothers with UC. CD influenced the type of delivery only when perianal disease was associated to colonic disease.
