Fundação de Amparo a Pesquisa do Estado da Bahia / O objetivo deste trabalho foi avaliar o efeito do tratamento periodontal sobre marcadores (PCR, albumina, colesterol e triglicerídeos) em indivíduos com Doença Renal Crônica (CRD) bem como sobre o curso da progressão dessa doença. Vinte e seis pacientes, idade média de 60 ( 11,2) anos, com Doença Renal Crônica estágios 3 e 4 com periodontite crônica não severa e severa receberam terapia básica periodontal. Parâmetros clínicos periodontais incluíram Índice de Placa (IP), Sangramento à Sondagem (SS), Profundidade de Bolsa à Sondagem (PBS), Nível de Inserção à Sondagem (NIS). A taxa filtração glomerular estimada (ml/min/1.73 m2) e níveis séricos de proteína C-reativa (mg/dl) (PCR), triglicerídeos (mg/dl), colesterol total (mg/dl) e albumina (g/dl) foram avaliados no dia zero e noventa dias após o tratamento periodontal. No dia zero, os percentuais médios de sítios com PBS &#8805; 4mm e NIS &#8805; 4mm eram de 23,7 ( 11) e 38,2 ( 16,5), respectivamente. Três meses após, os valores correspondentes diminuíram para 13,3 ( 8,0) e 33,4 ( 16,6). O percentual médio de sítios com PBS &#8805; 6mm e NIS &#8805; 6 mm diminuiu de 7,8 (8,6) e 24,5 (19,3) para 2,9 (5,1) e 23,8 (20,3). Os valores médios no dia zero de PCR, albumina, triglicerídeos e colesterol total eram de 1,0 mg/dl (1,0), 4,4 g/dl (0,4), 160 mg/dl (61,5), 200,1 mg/dl (36,9), enquanto que 90 dias após o tratamento os valores correspondentes foram de 0,8 mg/dl (0,6), 4,4 g/dl (0,3), 155,8 mg/dl (65,6), 199,5 mg/dl (46), respectivamente. Não havia diferença estatística entre os parâmetros laboratoriais, entre os dias 0 e 90. No dia 0, as taxas da filtração glomerular estimada foram de 41,6 ml/min/1.73m2 (13,1), enquanto no dia 90 esses valores foram de 45 ml/min/1.73m2 (15,7) (p<0.05). Concluiu-se que após o tratamento periodontal os parâmetros clínicos periodontais e a taxa de filtração glomerular estimada melhoraram significantemente e houve uma tendência para diminuição dos níveis de PCR. O significado clínico do aumento da taxa filtração glomerular estimada é discutível. Estudos longitudinais com tempos de observação mais longos são necessários para avaliar se o tratamento periodontal pode oferecer benefício para o paciente renal crônico. / The aim of the present study was to evaluate to effect of periodontal treatment in chronic renal disease (CRD) patients. 26 patients with CRD stages 3 and 4 with moderate and severe chronic periodontitis received periodontal basic therapy. Periodontal clinical parameters included plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD) and probing attachment level (PAL). Estimated glomerular filtration rate (ml/min/1.73m2) and serum levels of C-reactive protein (CRP) (mg/dl), triglicerids (mg/dl), total cholesterol (mg/dl) and albumin (g/dl) were collected on days 0 and 90, after periodontal treatment. On day 0, mean % of sites with PPD &#8805; 4mm and PAL &#8805; 4mm were 23,7 ( 11) e 38,2 ( 16,5), respectively. On day 90, the corresponding values decreased to 13,3 ( 8,0) e 33,4 (16,6). The mean % of sites with PPD &#8805; 6mm and PAL &#8805; 6mm decreased from 7,8 (8,6) and 24,5 (19,3) to 2,9 (5,1) e 23,8 (20,3), respectively (P<0,05). On day 0, the mean values of CRP, albumin, triglicerids and total cholesterol was a statistically 1,0 mg/dl (1,0), 4,4 g/dl (0,4), 160 mg/dl (61,5), 200,1 mg/dl (36,9), while the the corresponding values for day 90 were 0,8 mg/dl (0,6), 4,4 g/dl (0,3), 155,8 mg/dl (65,6), 199,5 mg/dl (46), respectively. On day 90, the levels of estimated glomerular filtration rate were 41,6 ml/min/1.73m2 (13,1), and on day 90 the corresponding values were 45 ml/min/1.73m2 (15,7) (p<0.05). The clinical significance of this improvement on estimated glomerular filtration rate is questionable. Further longitudinal studies with longer observation periods are necessary to evaluate if periodontal therapy may be beneficial for CRD patients.

Recently, the CKD was founded like an important cause of premature mortality, especially that caused by cardiovascular disease. This study intent was to identify and quantify cardiac morphofunctional alterations, and to verify the association between echocardiographic parameters and clinical variables, in a population with CKD stages G3A, G3B and G4, at conservative treatment. It is a cross-sectional study, including 55 patients with CKD stable disease for at least 1 year. We evaluated anthropometric measures, blood pressure values, creatinine, glomerular filtration rate, CKD stage, urine albumin-to-creatinine ratio, serum albumin, lipid profile, serum phosphorus, serum calcium, PTH levels, hemoglobin levels, Creactive protein levels, smoking, hypertension, diabetes and established cardiovascular disease. We observed high frequency of diastolic dysfunction (80%) and left ventricular hypertrophy (52,7%). The frequency of systolic dysfunction was 9,1% and valve cardiac calcification was 41,8%. Only one echocardiographic measure – the velocity of Sm wave – presented association with CKD stage. This measure is a marker of early systolic dysfunction. Neither the other echocardiographic parameters nor the presence of cardiac morphofunctional alterations presented association with CKD-related risk factors, only with traditional cardiovascular risk factors. / A DRC é um problema de saúde pública, com prevalência estimada em torno de 10% da população mundial. Cada vez mais, têm-se descoberto a relevância da DRC, desde seus estágios iniciais, como importante causa de morbi-mortalidade, em especial o aumento da morbi-mortalidade cardiovascular. O objetivo deste estudo foi avaliar uma população de pacientes com DRC estágios G3A, G3B e G4, em tratamento conservador, a fim de identificar e quantificar a presença de alterações cardíacas morfofuncionais, e verificar associação entre parâmetros ecocardiográficos de função sistólica e diastólica com variáveis clínicas. Trata-se de um estudo transversal que incluiu 55 pacientes adultos com DRC estável há pelo menos 1 ano. Foram avaliadas medidas antropométricas, valores de pressão arterial, creatinina, taxa de filtração glomerular estimada, estágio da DRC, relação albumina/creatina urinária, albumina, lipidograma, fósforo, cálcio, PTH, hemoglobina, proteína C reativa, tabagismo, presença de hipertensão arterial, diabetes e doença cardiovascular em geral. Observou-se alta frequência de disfunção diastólica (80%) e hipertrofia ventricular esquerda (52,7%) nesta população. A frequência de disfunção sistólica foi de 9,1% e de calcificação valvar foi de 41,8%. Apenas uma medida ecocardiográfica – a onda sm septal – apresentou associação com o estágio da DRC. Tal medida é um marcador de disfunção sistólica precoce. As demais medidas ecocardiográficas, bem como as alterações morfofuncionais, apresentaram associação apenas com fatores de risco cardiovascular tradicionais.

Pacientes em hemodiálise (HD) estão sob estresse oxidativo, o que leva à formação de espécies reativas de oxigênio (EROs). Toxinas urêmicas, a própria hemodiálise e o comprometimento do sistema antioxidante induzem a formação de EROs. Dentre os antioxidantes está o Selênio (Se), mineral que a literatura já relata deficiência em pacientes em HD. Considerando a importância da atividade antioxidante nestes pacientes com doença renal crônica (DRC) em HD, o objetivo deste estudo foi avaliar o efeito da suplementação com castanha-do-brasil nos níveis de Se e na atividade da glutationa peroxidase (GSH-Px) em pacientes nestas condições. Foram estudados 81 pacientes em HD (52,0 &#177; 15,2 anos, tempo média de HD de 82,3 &#177; 91,4 meses e IMC de 24,4 &#177; 4,4 kg/(m)2) das clínicas RenalCor e RenalVida do Rio de Janeiro. Os pacientes receberam uma castanha (&#8776; 5g), cerca 290&#181;g Se, por dia, durante três meses. A concentração de Se foi determinada por espectrometria de absorção atômica com geração de hidretos (HITACHI&#174;, Z-500). A atividade da enzima GSH-Px foi medida usando kit comercial RANDOX&#174;. Os níveis de Se no plasma (18,8 &#177; 17,4 &#181;g/L) e no eritrócito (72,4 &#177; 37,4 &#181;g/L) antes da suplementação estavam abaixo da faixa da normalidade (60-120 &#181;g/L no plasma e de 90-190 &#181;g/L no eritrócito) e após a suplementação os níveis plasmáticos e eritrocitários aumentaram para 104,0 &#177; 65,0 &#181;g/L e 244,1 &#177; 119,5 &#181;g/L (p&#60; 0,0001), respectivamente. A atividade de GSH-Px também aumentou após a suplementação passando de 46,4 &#177; 14,9 U/gHb para 55,9 &#177; 23,6 U/gHb (p&#60; 0,0001). Antes da suplementação 11% dos pacientes apresentaram atividade da GSH-Px abaixo da normalidade (27,5 - 73,6 U/gHb) e, após a suplementação todos pacientes apresentaram atividade da GSH-Px normal. Os resultados mostraram que os pacientes estudados apresentaram Se plasmático e eritrocitário abaixo dos valores normais e o consumo de apenas uma castanha-do-brasil por dia (5g) foi eficaz no aumento da concentração de Se e na atividade da GSH-Px nos pacientes em HD; além disto, ela pode contribuir para a melhora da condição de estresse oxidativo desses pacientes. / Hemodialysis (HD) patients may undergo oxidative damage which causes reactive oxygen species (ROS) formation. Uremic toxins, HD treatment and the decrease in antioxidant system are known to result in the ROS generation. Selenium (Se) has a role as an antioxidant and studies report Se deficiency in these patients. Considering the importance of the antioxidant activity in patients with chronic kidney disease (CKD) in HD, the aim of this work was evaluate the effect of Brazilian nuts (main food source) supplementation on levels of Se and glutathione peroxidase (GSH-Px) activity in HD patients. A total of 81 HD patients (52.0 &#177; 15.2 years old, average time on dialysis was 82.3 &#177; 91.4 months and BMI of 24.9 &#177; 4.4 kg/m2) from RenalCor and RenalVida Clinics in Rio de Janeiro, Brazil were studied. The patients received one nut (&#8776; 5g), average of 290 &#181;g Se, each day during three months. The Se concentration was determined by atomic absorption spectrophotometry with hydride generation (HITACHI&#174;, Z-500). The levels of GSH-Px were measured by using RANDOX&#174; commercial kits. The Se levels in plasma (18.8 &#177; 17.4 &#181;g/L) and erythrocyte (72.4 &#177; 37.9 &#181;g/L) before supplementation were below the normal range (60-120 &#181;g/L for plasma and 90-190 &#181;g/L for erythrocyte) and after nut supplementation, the plasma levels increased to 104.0 &#177; 65.0 &#181;g/L and erythrocytes to 244.1 &#177; 119.5 &#181;g/L (p&#60;0.0001). The activity of GSH-Px also increased after supplementation from 46.6 &#177; 14.9 U/ gHb to 55.9 &#177; 23.6 U/gHb (p&#60;0.0001). Before supplementation, 11% of patients had activity of GSH-Px below the normal range (27.5 - 73.6 U/gHb) and, after supplementation, all patients showed activity of GSH-Px within the normal range. The data revealed that the investigated patients had erythrocyte and plasma Se levels below the normal values and the consumption of just one Brazil nut each day (5g) was effective to increase on Se concentration and GSH-Px activity of the patients in HD, thus contributing to improve the antioxidant condition of these patients.

No. of bitstreams: 1 MariaDeJesusFreitas.pdf: 6269278 bytes, checksum: eab572eb0c1e9cb928b6119c964b54a4 (MD5) Previous issue date: 2017-10-13 / Introduction: Chronic Kidney Disease is a serious public health problem. Diabetes Mellitus and Arterial Hypertension are the main causes of the disease, easily diagnosed and treated by programs used in public health. Primary Health Care is the level of preferential attention to promote prevention and early diagnosis of cases of the disease. Objective: To evaluate the attention given to the person with Chronic Renal Disease in Basic Health Care from the perspective of patients, family members and health professionals. Methodology: Qualitative evaluation research performed in households of patients with Chronic Renal Disease, hemodialysis units and Basic Health Units of Belém-Pará. Participants were patients with chronic kidney disease, older than 19 years old, diabetic and hypertensive, living in Belém and who undertook hemodialysis in 2015, through the Unified Health System; family members indicated by the patients; physicians and nurses of Primary Health Care. In the analysis, the technique of Content Analysis in the Thematic modality was used. Results: The first article evaluated the Trajectories of Care of Chronic Renal Disease patients, seeking to identify the functions of Primary Health Care. Three Trajectories were identified: 1) Did not seek the Basic Health Unit; 2) He sought the Basic Health Unit, but did not receive the diagnosis; 3) Received a diagnosis in the Basic Health Unit and was referred to the specialty. The second article evaluated the attention given by the Basic Health Care to people with Chronic Kidney Disease, from the perspective of the interviewees, whose analysis resulted in two categories: 1) Primary Care is the place of people with Chronic Disease? (Distrust in Primary Care, Primary Care does not deal with Chronic Kidney Disease, Indifference of the multiprofessional team, Ineffectiveness in communication in the care network); 2) Basic Health Care loses contact with users on hemodialysis treatment. Conclusion: The care trajectories revealed irregular flows of care in the care network. Patients and their families did not perceive Basic Health Care as a place of care. For most professionals, Basic Health Care did not perform its function as coordinator of care, did not identify Chronic Kidney Disease and did not guarantee the maintenance of the link after starting treatment. / Introdução: A Doença Renal Crônica constitui um grave problema de saúde pública. Diabetes Mellitus e Hipertensão Arterial, são as principais causas da doença, facilmente diagnosticadas e tratadas por programas utilizados na saúde pública. Atenção Básica à Saúde é o nível de atenção preferencial para promover prevenção e diagnosticar precocemente os casos da doença. Objetivo: Avaliar a atenção prestada à pessoa portadora de Doença Renal Crônica na Atenção Básica em Saúde, na perspectiva de usuários, familiares e profissionais de saúde. Metodologia: Pesquisa de avaliação qualitativa, realizada em domicílios de portadores de Doença Renal Crônica, unidades de hemodiálise e Unidades Básicas de Saúde de Belém-Pará. Participaram portadores de Doença Renal Crônica, maiores de 19 anos, diabéticos e hipertensos, residentes em Belém e que iniciaram hemodiálise em 2015, pelo Sistema Único de Saúde; familiares indicados pelos usuários e; médicos e enfermeiras da Atenção Básica à Saúde. Na análise, utilizou-se a técnica de Análise de Conteúdo na modalidade Temática. Resultados: O primeiro artigo avaliou as Trajetórias Assistenciais de portadores de Doença Renal Crônica, buscando identificar as funções da Atenção Básica à Saúde. Foram identificadas três Trajetórias Assistenciais: 1) Não procurou a Unidade Básica de Saúde; 2) Procurou a Unidade Básica de Saúde, mas não recebeu o diagnóstico; 3) Recebeu diagnóstico na Unidade Básica de Saúde e foi encaminhado para a especialidade. O segundo artigo avaliou a atenção prestada pela Atenção Básica à Saúde para pessoas com Doença Renal Crônica, na perspectiva dos entrevistados, cuja análise resultou em duas categorias: 1) Atenção Básica é lugar de pessoas com Doença Crônica? (Desconfiança na Atenção Básica, a Atenção Básica não trata de Doença Renal Crônica, Indiferença da equipe multiprofissional, Ineficácia na comunicação na rede de atenção); 2) A Atenção Básica perde o contato com os usuários em tratamento de hemodiálise. Conclusão: As Trajetórias Assistenciais revelaram fluxos irregulares de atendimento na rede de atenção. Usuários e familiares, não perceberam a Atenção Básica à Saúde como lugar de cuidado. Para a maioria dos profissionais, a Atenção Básica à Saúde não fez sua função de garantiu a manutenção do vínculo após o início do tratamento.

A utilização da Internet pode trazer benefícios ao cuidado em saúde quando utilizada como fonte de informação em saúde geral e bucal e suporte social promovendo o empoderamento dos indivíduos, o que pode ser especialmente importante e benéfico para pais de crianças com doença renal crônica. A DRC inclui todas as condições que são capazes de provocar a perda progressiva da função renal podendo levar à diálise e, como última consequência à necessidade de transplante. Em crianças, a doença é devastadora e apresenta taxas de mortalidade elevadas, sobretudo em pacientes pediátricos em diálise, quando comparadas à de crianças normais. Por sua vez, esses pacientes apresentam diversas manifestações bucais que podem agravar sua saúde já comprometida. A complexidade dessas patologias e a necessidade de cuidados contínuos e intensivos demandam habilidades de pais, que raramente têm experiência e conhecimento prévios para o cuidado. A Internet pode não ser uma fonte primária no auxílio para a tomada de decisão em saúde, mas inúmeras pesquisas têm mostrado que ela se tornou uma fonte de informação em saúde importante para pais de crianças acometidas com alguma doença, a fim de complementar, mas não substituir, as informações fornecidas por médicos e profissionais de saúde, além de dirimir dúvidas e trocar experiências com pessoas em circunstâncias semelhantes. Assim, diante da gravidade da DRC e das inúmeras manifestações bucais, nós investigamos em um estudo transversal, a utilização da Internet para a busca de informações em saúde por pais de crianças acometidas. O estudo compreendeu 111 pais e cuidadores de crianças com doença renal crônica sob tratamento, em um centro de nefrologia pediátrica brasileiro. Os resultados obtidos, por meio de um formulário, demonstraram que dos pais que buscavam informações de saúde na Internet, 90% (80/89) buscavam por informações sobre o problema de saúde dos seus filhos. Por outro lado, somente 20% (18/89) disseram procurar por informações sobre saúde bucal. A maioria dos pais que buscavam informação sobre a doença usam a Internet diariamente (66%)(53/80). Eles buscaram sobretudo obter mais informações sobre a doença (94%). Além disso, 93% consideraram útil a informação encontrada, sendo que 78% alegaram que entenderam melhor o problema. No entanto, mais da metade (52%) preferiram não comentar com o médico. O estudo traça um perfil de pais e cuidadores de crianças com DRC quanto ao uso da Internet como fonte de informação em saúde. Podemos concluir que há bastante interesse por informações sobre o problema de saúde da criança, mas pouco interesse por informações de saúde bucal. Os resultados obtidos serão úteis para posterior elaboração de conteúdos educacionais e informativos que utilizem a tecnologia de informação e comunicação para o cuidado e educação em saúde e o empoderamento de pais e pacientes com doença renal crônica. / The use of Internet can bring benefits to health care when used as a source of information for oral, general health and also as a social support to promote individual´s empowerment. This fact can be very important for parents of children with chronic kidney disease (CKD). CKD includes all conditions that lead to progressive loss of renal function, placing the individual in a dialysis condition and as a last consequence leading him/her to renal transplant. In children, the disease may cause several impairments, presenting high mortality rates compared to healthy children, mainly for individuals who are undergoing dialysis. These patients display several oral manifestations that can affect their systemic conditions in a more severe aspect. The severity of these pathologies and the needs for continuous care demand skills and abilities that are rarely previously delivered to parents/caretakers. The Internet may not be the primary health information source, though several studies have shown that Internet has become an important source of health information for impaired children and their parents. This information can supplement, but not replace the ones supplied by physicians and other health professionals. Though, by means of this tool, people can also sort out their doubts and exchange information with others who are in similar contexts. Hence, the aim of this cross-sectional study was to investigate how the Internet has been used by parents of CKD children, to look for health information. The results were obtained by means of a filled form, and showed that 90% (80/89) of parents/caretakers who use Internet looked for health information about their children´s health problems. On the other hand, only 20% (18/89) of parents/caretakers had looked for information about oral health. More than half (66%)(53/80) of these parents/caretakers use the Internet daily. The most common reason (94%) for using the Internet was to find more information about of the child\'s condition. Ninety-three percent found the Internet useful. Seventy-eight percent found that the Internet provided further understanding into their child\'s condition. However, more than half (52%) prefers not to talk to the physician. Based on that, this study aimed to design the profile of parents/caretakers of children with CKD, concerning the use of Internet as a source of health information. It could be concluded that there is a large interest about children´s health problems general, but not too much about oral health information. The results obtained may support to the development of further educational and informative contents that use information and communication technology to support parents/caretakers of CKD children.

Introdução: Doença Renal Crônica (DRC) consiste, principalmente, na redução da capacidade dos rins em filtrar substâncias tóxicas, acarretando alterações metabólicas e hormonais. Em fases terminais, a terapia renal substitutiva (TRS) torna-se necessária, e o transplante renal tem sido relatado como a melhor opção terapêutica e de reabilitação para pacientes com DRC. Entretanto a DRC e o transplante renal podem afetar a qualidade de vida relacionada à saúde (QVRS) desses pacientes, podendo ser influenciada por aspectos da saúde física e mental, tais como os sintomas depressivos (SDs). Objetivos: Caracterizar os pacientes com DRC, após transplante renal, em um município do estado de São Paulo quanto aos aspectos sociodemográficos, econômicos e clínicos; descrever a QVRS e os SDs; correlacionar a QVRS e os fatores sociodemográficos, econômicos e clínicos; comparar a QVRS, segundo as dimensões do SF-36, entre os pacientes sem e com SDs e correlacionar a QVRS com os SDs. Material e Método: Trata-se de um estudo transversal, de natureza quantitativa, que incluiu pacientes que realizaram transplante renal entre 6 e 24 meses retroativos da data de início da coleta de dados, maiores de 18 anos e faziam acompanhamento no ambulatório de Transplante Renal do HCFMRP-USP, na cidade de Ribeirão Preto-SP. Foram excluídos os pacientes que apresentavam instabilidade clínica, o que totalizou a inclusão de 60 pacientes no estudo. Os instrumentos utilizados foram: instrumento para caracterização dos participantes, o qual foi adequado ao estudo e submetido à avaliação de conteúdo, Medical OutcomesStudy (MOS SF-36) para avaliação da QVRS e o Inventário de Depressão de Beck (IDB) para avaliar os SDs. Os dados foram obtidos por meio de entrevista individual com o paciente e de consulta ao prontuário. A coleta de dados ocorreu de abril a agosto de 2011. O projeto foi aprovado pelo Comitê de Ética em Pesquisa da Escola de Enfermagem de Ribeirão Preto - Universidade de São Paulo. A análise dos dados constou da análise estatística descritiva; coeficiente de correlação de Pearson (r) para verificar a correlação entre os domínios do SF-36 com o escore total do IBD; análise de variância (ANOVA) para comparar os domínios do SF-36, nos grupos com ausência e com presença de SD; Teste Exato de Fisher para verificar a associação entre as variáveis qualitativas relacionadas ao escore de IDB e às diversas variáveis independentes, além disso, a quantificação da associação foi mensurada por meio de modelos de regressão logística na qual calculamos o OddsRatio Bruto com seus respectivos intervalos de confiança de 95%. Todas as análises estatísticas foram realizadas com a utilização do software estatístico SAS® 9.0. Valores de p menores que 0,05 foram considerados significativos. Resultados: Dos 60 pacientes, 51 eram adultos e 9 idosos; 41 eram homens e 19 eram mulheres. Os domínios do SF-36 que obtiveram menores escores médios foram: aspectos físicos (59,58), capacidade funcional (64,67) e vitalidade (71,42), e os que obtiveram maiores escores médios foram: aspectos sociais (79,79), dor (78,12) e aspectos emocionais (75,56). Quanto aos escores do IDB, 43 pacientes apresentaram ausência de SDs, 12 apresentaram disforia e 5 apresentaram SDs classificados entre leves e moderados. Não possuir trabalho aumentou a chance em 7,7 vezes de ter SDs que ter trabalho. Os pacientes com ausência de SDs apresentaram escores médios mais elevados nos domínios do SF-36, refletindo melhor QVRS, quando comparados aos pacientes com algum grau de SDs, com notória diferença na comparação (p<0,05). Encontramos correlações negativas entre os domínios do SF-36 e os escores do IDB, ou seja, à medida que aumentaram os escores de SDs, decresceram os escores médios nos domínios de QVRS. Tais correlações apresentaram p valor <0,05, exceto para o domínio estado geral de saúde. Conclusão: A presença de SDs se relacionou negativamente com a QVRS dos pacientes transplantados renais, evidenciando a necessidade de incluir a avaliação dos sintomas depressivos e respectivos atendimentos das alterações quando identificadas, na prática clínica que engloba a atuação do enfermeiro, para otimizar a QVRS desses pacientes. / Introduction: Chronic Kidney Disease (CKD) mainly involves the decrease in the kidney\'s ability to filter toxic substances, causing metabolic and hormonal alterations. In terminal stages, renal replacement therapy (RRT) becomes necessary, and kidney transplantation has been reported as the best treatment and rehabilitation option for CKD patients. CKD and the kidney transplantation can affect these patients\' healthrelated quality of life (HRQoL) though, which can be influenced by physical and mental health aspects, including depressive symptoms (DS). Aims: Characterize CKD patients after kidney transplantation in a city in São Paulo State regarding socio-demographic, economic and clinical aspects; describe HRQoL and DS; correlate HRQoL with the socio-demographic, economic and clinical factors; compare HRQoL, according to the SF-36 dimensions, between patients with and without DS and correlate HRQoL with the DS. Material and Method: This quantitative and crosssectional study included patients who underwent a kidney transplantation between 6 and 24 months before the start of data collection, over 18 years of age and monitored at the Kidney Transplantation outpatient clinic of HCFMRP-USP in RibeirãoPreto-SP, Brazil. Clinically unstable patients were excluded, totaling 60 patients included in the study. The following instruments were used: patient characterization instrument, which was adapted to the study and submitted to content assessment, Medical Outcomes Study (MOS SF-36) for HRQoL assessment and Beck\'s Depression Inventory (BDI) for the assessment of DS. Data were collected through an individual interview with the patient and consultation of patient files. Data collection took place between April and August 2011. Approval for the project was obtained from the Institutional Review Board at the University of São Paulo at RibeirãoPreto College of Nursing. Data analysis comprised descriptive statistical analysis; Pearson\'s correlation coefficient (r) to check the correlation between the SF-36 domains and the total BDI score; variance analysis (ANOVA) to compare the SF-36 domains in the groups with and without DS; Fisher\'s Exact Test to verify the association between the qualitative variables related to the BDI score and the different independent variables. In addition, the association was quantified through logistic regression models, in which the Gross Odds Ratio was calculated with its respective 95% confidence intervals. SAS® 9.0 statistical software was used for all statistical analyses. P-values inferior to 0.05 were considered significant. Results: 51 out of 60 patients were adults and 9 elderly; 41 were men and 19 women. The SF-36 domains with the lowest mean scores were: physical aspects (59.58), functional capacity (64.67) and vitality (71.42); while the domains with the highest mean scores were: social aspects (79.79), pain (78.12) and emotional aspects (75.56). As for the BDI scores, 43 patients presented absence of DS, 12 dysphoria and 5 DS classified between mild and moderate. Not having a job increased the chance of DS by 7.7 times. Patients without DS obtained higher mean scores on the SF-36 domains, reflecting a better HRQoL in comparison with patients with some degree of DS, with a statistically significant difference (p<0.05). We found negative correlations between the SF-36 domains and the BDI scores, that is, to the extent that DS scores increased, the mean scores on the HRQoL domains dropped. The p-value for these correlations was <0.05, except for the general health status domain. Conclusion: The presence of DS was negatively related with the HRQoL of kidney transplant patients, evidencing the need to include the assessment of depressive symptoms and attend to the alterations when identified in clinical practice, which includes nursing actions, in order to improve these patients\' HRQoL.

A hiperfosfatemia em pacientes com doença renal crônica pode levar a complicações como o desenvolvimento do distúrbio mineral e ósseo (DMO) e a calcificação de tecidos moles. As estratégias terapêuticas para o controle da hiperfosfatemia na DMO visam à redução da ingestão de fósforo, redução da absorção intestinal por meio de quelantes e remoção por meio da diálise. O objetivo desse estudo foi elaborar e aplicar uma tabela de contagem de fósforo (TCF) para controle da hiperfosfatemia em pacientes em hemodiálise. Foram selecionados 50 pacientes, os quais tiveram o uso de quelantes de fósforo suspenso trinta dias antes do início da intervenção. Foi realizada a avaliação do estado nutricional (EN) por meio da avaliação subjetiva global, índice de massa corporal e coletado dados dietéticos por meio de registro alimentar (RA). Após 30 dias da suspensão do quelante (T0), no final do 1º e 2º mês de intervenção (T1 e T2) foram realizadas coletas de sangue para análise de exames bioquímicos, visando auxiliar na avaliação do EN e observar os níveis séricos de fósforo, cálcio, hormônio da paratireoide (PTH) e produto cálcio-fósforo (CaxP). No T0 os pacientes receberam orientação nutricional por meio da TCF, a qual seguiram por um período de 2 meses, com acompanhamento quinzenal. Ao final do estudo foi realizada nova avaliação do EN e aplicado novo RA. Não foi encontrada alteração nos níveis séricos de fósforo e no produto CaxP ao final da intervenção. Já o cálcio sérico reduziu de T0 para T1 (p=0,05). Quando a amostra foi classificada de acordo com a aderência à TCF, o grupo aderente não apresentou alteração do fósforo e cálcio séricos, porém o produto CaxP do T1 (p=0,05) e T2 (p=0,02) diminuíram em relação ao T0. Já para o grupo não aderente houve aumento de T0 para T2 para o fósforo sérico (p=0,007) e produto CaxP (p=0,03), assim como de T1 para T2 (p=0,05 e p=0,05 respectivamente). O cálcio sérico não se alterou nesse grupo. O PTH aumentou ao final do estudo no grupo total (p<0,001), no aderente (p=0,002) e no não aderente (p=0,002). Não foi observado prejuízo do EN e alteração na ingestão de fósforo segundo o RA após a intervenção. Esse estudo mostrou que a TCF auxilia no controle dos níveis séricos de fósforo, talvez sem a necessidade do uso de quelantes de fósforo ou o uso em doses menores e demonstrou, também, que se for seguida corretamente permite ao paciente o autoajuste da dieta. / The hyperphosphatemia in patients with chronic kidney disease can lead to complications such as the development of mineral and bone disorder (BMD) and soft tissue calcification. The therapeutic strategies for the control of hyperphosphatemia in patients with BMD include intake reduction of phosphorus, reduction of the intestinal absorption through chelation and removal by dialysis. The aim of this study was to develop and apply a phosphorus counting table (PCT) for the control of hyperphosphatemia in hemodialysis patients. Were selected 50 patients and they had phosphate binders suspended thirty days prior to the start of the intervention. At this period was evaluated the nutritional status (NS) by subjective global assessment, body mass index and collected dietetic information through food records (FR). After 30 days of suspension of the phosphate binder (T0), at the end of the 1st and 2nd month of intervention (T1 and T2) were collected blood samples for analysis of biochemical tests to assist in the evaluation of NS and to analyze the serum phosphorus, serum calcium, serum parathyroid hormone (PTH) and calcium-phosphorus (CaxP) product. At T0 the patients received nutrition orientation through the PCT, which was followed by a period of two months monitored biweekly. At the end of the study was realized a new evaluation of the NS and applied new FR. There was no change in serum phosphorus levels and the CaxP product in the end of intervention. Serum calcium decreased in time T0 to T1 (p=0.05). When the sample was divided according to the adherence to PCT, the adherent group showed no change in serum phosphorus and calcium, however the CaxP product at T1 (p=0.05) and T2 (p=0.02) decreased in respecting T0. Whereas non-compliant group showed an increase at T0 to T2 for phosphorus serum (p=0.007) and CaxP product (p=0.03) and, too, increase at T1 to T2 (p=0.05 and p=0.05, respectively). The serum calcium didn\'t change in this group. PTH increased at the end of the study for the total group (p<0.001), adherent group (p=0.002) and non-compliant group (p=0.002). There was no damage to the NS and change in phosphorus intake according to FR after the intervention. This study showed that PCT assists in the control of serum phosphorus, perhaps without the use of phosphate binders or to use a reduction doses, and showed that if it was followed correctly allows the patient to make selfadjust diet.

Les microARNs sont reconnus comme des régulateurs essentiels de l'expression des protéines. Des anomalies dans leur fonction sont associées au développement de nombreuses pathologies.tiel des microARNs en tant que biomarqueurs ou cibles thérapeutiques dans une grande variété de pathologies. Dans le cadre de cette thèse, nous avons étudié :1) L'association des microARNs urinaires avec l'évolution de la maladie rénale chronique (MRC) chez l'adulte. La prévalence de la MRC est actuellement estimée à 5-10% de la population et est en constante augmentation. La détection précoce et l'identification de patients ayant une MRC progressant rapidement vers l'insuffisance rénale sont la clé pour une meilleure prise en charge de ces patients. Actuellement les outils non-invasifs comme l'albuminurie ou l'estimation du débit de filtration glomérulaire manquent de précision. Dans notre travail, nous avons tenté d'identifier les modifications urinaires des microRNAs afin d'identifier de nouveaux biomarqueurs non-invasifs associés à la progression de la MRC. Nous avons analysé les modifications des microARNs urinaires par séquençage à haut débit dans des échantillons d'urine de 70 patients atteints de MRC et corrélé leurs profils d'expression à la progression de la maladie. Cela a amené à l'identification de 25 microARNs urinaires (pvalue ajustée <0.05) potentiellement associés à la progression de la MRC. Parmi ceux-là, quatre microARNs (hsa-miR-34c-5p, hsa-miR-410-3p, hsa-miR-301b-3p, and hsa-miR-145-5p) ont été sélectionnés pour être validés dans une cohorte indépendante de 52 patients atteints de MRC. L'augmentation de l'abondance urinaire de hsa-miR-145-5p a été confirmée comme étant associée à la progression de la MRC. Des analyses in vitro de l'effet de l'inhibition de hsa-miR-145-5p dans les cellules rénales ont mis en évidence que ce microARN semblait être impliqué dans le processus de nécrose. En conclusion, cette étude nous a permis d'identifier hsa-miR-145-5p comme Ainsi, de nombreuses études s'intéressent au potenmarqueur potentiel de la progression de la MRC. 2) La présence de microARNs urinaires associés à la néphropathie obstructive, une maladie fréquemment rencontrée chez les enfants qui peut conduire, dans les cas graves, à l'insuffisance rénale précoce. Dans cette étude, nous avons utilisé la biologie des systèmes et avons combiné des données microARN et ARNm de néphropathie obstructive humaine et animale pour obtenir des informations sur les mécanismes possibles impliqués dans cette maladie. En particulier, nous avons étudié simultanément le miRNome urinaire de nourrissons présentant une obstruction de la jonction pyélo-urétérale et le miRNome et le transcriptome tissulaire rénal chez la souris dans le modèle animal d'obstruction urétérale unilatéral (OUU) partiel et néonatal. Plusieurs centaines de microARNs et d'ARNms étant modifiés, la combinaison des microARNs des deux espèces avec les ARNms cibles associés a permis de sélectionner les 5 microARNs et 35 ARNms les plus fortement associés à la néphropathie obstructive. Une validation in vitro et in vivo a mis en avant que let-7a-5p et miR-29-3p ainsi que deux nouvelles cibles potentielles, l'E3 ubiquitin-protein ligase (DTX4) et neuron navigator 1 (NAV1) étaient dérégulées au cours de cette pathologie. Cette étude est la première à corréler le modèle animal d'OUU partiel et néonatal avec l'obstruction pyélo-urétérale chez l'Homme dans une analyse intégrée de biologie des systèmes. Nos résultats ont révélé let-7a et miR-29b en tant que molécules potentiellement impliquées dans le développement de la fibrose dans la néphropathie obstructive via le contrôle de DTX4 chez l'homme et la souris, ce qui n'aurait pas été identifiable autrement. / MicroRNAs are now recognized as key players in the regulation of proteins and any abnormality in their function is a cause for pathway instability, leading to pathological conditions. Numerous reports from a variety of pathologies provide new data about microRNAs function, their targets and their potential as biomarkers and possible ways to control microRNAs' expression for potential therapeutic purpose. A number of reports also connect microRNAs with pathological conditions in the kidney and point to the use of microRNAs as biomarkers for diagnosis and prognosis of kidney disease in blood, serum, tissue and urine samples. In this thesis, we researched:1) A possible role of the microRNAs in the progression of adult chronic kidney disease (CKD), a disease representing a global burden with the tendency to rise worldwide. Progression of CKD is still very hard to detect non-invasively with the currently used clinical tools (eGFR and albuminuria). In our work we studied alterations of the level of the microRNAs in human urine samples of patients with fast or slow progression of CKD, in order to identify new potential biomarkers for non-invasive progression of CKD. Using Next Generation Sequencing, we analyzed urinary microRNA modifications in urine samples of 70 patients with established CKD and correlated their expression profiles to disease progression. This lead to the identification of 25 urinary microRNAs significantly associated to CKD progression (adjusted pvalue<0.05). Among those, four microRNAs (hsa-miR-34c-5p, hsa-miR-410-3p, hsa-miR-301b-3p, and hsa-miR-145-5p) were selected for validation in an independent cohort of 52 patients with CKD. Increased urinary abundance of hsa-miR-145-5p was confirmed to be associated to progression of CKD. In vitro exploration of the effects of hsa-miR-145-5p inhibition in human kidney cells showed that the microRNA seemed to be involved in necrotic processes. In conclusion we have identified hsa-miR-145-5p as potential urinary microRNA marker of CKD progression. 2) The identification of microRNAs associated to obstructive nephropathy, a frequently encountered disease in children that can lead, in severe cases, to end stage renal disease (ESRD). In this study we used a comprehensive system biology analysis in which we combined micro- and mRNA data from human and animal obstructive nephropathy to obtain information on possible mechanisms involved in this disease. In particular, we have studied in parallel the urinary miRNome of infants with ureteropelvic junction (UPJ) obstruction and the kidney tissue miRNome and transcriptome of the corresponding neonatal partial unilateral ureteral obstruction (UUO) mouse model. Several hundreds of microRNAs and mRNAs displayed changed abundance during disease. Combination of microRNAs in both species and associated mRNAs let to the prioritization of 5 microRNAs and 35 mRNAs associated to disease. In vitro and in vivo validation identified consistent dysregulation of let-7a-5p and miR-29-3p and new potential targets, E3 ubiquitin-protein ligase (DTX4) and neuron navigator 1 (NAV1). Our study is the first to correlate a mouse model of neonatal partial UUO with human UPJ obstruction in a comprehensive systems biology analysis. Our data revealed let-7a and miR-29b as molecules potentially involved in the development of fibrosis in UPJ obstruction via the control of DTX4 in both man and mice that would not be identified otherwise.

Bakgrund: Kronisk njursvikt är ett globalt växande folkhälsoproblem. Många patienter är i ett stadie i sin sjukdom som kräver hemodialysbehandling, något som är förenat med en högre dödlighet och en väsentligt lägre livskvalité. Komplementär och alternativ medicin (KAM) kan därmed vara ett aktuellt ämne att studera som ett tillägg till traditionell konventionell medicin för att lindra symtom. Erikssons vårdteori utgjorde teoretisk referensram för detta examensarbete. Syfte: Att undersöka om fysiska- och mentala symtom samt livskvalitet hos patienter som genomgår hemodialys kan påverkas av alternativa- och komplementära behandlingsalternativ. Metod: En allmän litteraturöversikt där 10 kvantitativa artiklar valt ut för att användas. För att finna relevanta artiklar som besvarade studiens syfte användes databaserna: PubMed, CINAHL, PsykINFO och Cochrane Library. En om modifiering av Olsson och Sörensens (2011) kvaliteétsmall användes för kvalitetsgranskning av de kvantitativa artiklarna. Resultatanalysmetoden som användes var utarbetad av Forsberg och Wengström (2016), analysen genomfördes för att på ett enklare sätt identifiera likheter och skillnader mellan de utvalda artiklarna.  Resultat: Användning av KAM visade varierande resultat. I studierna fanns en reducering av smärta och klåda efter att patienterna lyssnat på livesång och utfört aromaterapi. Gällande depression, ångest och livskvalité fanns ett varierande resultat beroende på vilken behandlingsmetod som användes. Två kategorier och sju underkategorier identifierades. Slutsats: Användningen av KAM kan ha positiv påverkan på den fysiska- och mentala symtomen samt livskvaliteten. Mer forskning kring ämnet krävs för att sjukvårdspersonalen ska kunna erbjuda detta som ett komplement i omvårdnaden. / Background: Chronic kidneyfailure is a growing global public health problem. Many patients are at a stage in their illness that requires hemodialysis treatment, something that is associated with a higher mortality rate and a significantly lower quality of life. Complementary and alternative medicine is a topical subject to study as a supplement to the traditional medicine to reduce symptoms. Eriksson's theory of care was the theoretical reference frame for this thesis. Aim: Investigating whether physical and mental symptoms as well as quality of life in patients undergoing hemodialysis can be influenced by alternative and complementary treatment options. Method: A literature review based on 10 quantitative articles. To find relevant articles that answered the study's purpose PubMed, CINAHL, PsykINFO and Cochrane Library were used as databases. A modification of Olsson and Sörensen's (2011) quality template was used for quality review of the quantitative articles. The results analysis method used was developed by Forsberg and Wengström (2016), the analysis was carried out in order to more easily identify similarities and differences between the selected articles. Results: The use of CAM therapy showed varying results. In the studies, there was a reduction in pain and itching after the patients listened to live singing and performed aromatherapy. Regarding depression, anxiety and quality of life, there were varying results depending on the treatment method used. Two categories and seven subcategories are identified. Conclusion: The use of CAM medicine can have positive effects on the physical and mental quality of life. More research on the subject is required before the healthcare staff will be able to offer this as a complement to the nursing care.

Background In the event of an acute coronary syndrome (ACS), the risk of death and complications such as stroke and re-infarction is high during the first month. Diabetes, impaired kidney function, elevated markers of systemic inflammation and high level of platelet reactivity have all been associated with worsened prognosis in ACS patients. Impaired kidney function is a condition with high cardiovascular morbidity and there is an established association between level of kidney function and outcome in the event of an ACS. Aims We sought to investigate the level of platelet reactivity during the first days of an ACS and specifically the level of platelet reactivity in patients with different conditions associated with worsened prognosis in the event of an ACS. We also wanted to investigate the prognostic impact of baseline levels of cystatin C as well as the importance of decreasing kidney function during the first days of an ACS. Methods We included 1028 unselected patients with ACS or suspected ACS during the years 2002 and 2003, of which 534 were diagnosed with an acute myocardial infarction (AMI). Blood samples for measuring platelet aggregation, cystatin C levels and other clinically important biomarkers were collected day 1, 2, 3 and 5 following admission. Platelet reactivity was measured using 2 different methods. Platelet aggregation was measured using Pa-200, a particle count method, based on scattering of laser light. PFA 100 is a method of measuring primary hemostasis in whole blood. Results Platelet aggregation and comorbidities. We found an increase in platelet aggregation when an ACS was complicated by an infection and there was an increased frequency of aspirin non-responsiveness in patients suffering from pneumonia during the first days of an ACS. Furthermore, we found an independent association between levels of C-reactive protein and platelet aggregation. During the first 3 days following an acute myocardial infarction, platelet aggregation increased despite treatment with anti-platelet agents. Platelet aggregation was found to be more pronounced in patients with diabetes. Patients with impaired kidney function, showed increased platelet aggregation compared to patients with normal renal function, however, this difference was explained by older age, higher prevalence of DM and levels of inflammatory biomarkers. We found no independent association between chronic kidney disease (CKD) and levels of platelet aggregation. Kidney function and outcome Serum levels of cystatin C on admission had an independent association with outcome following an acute myocardial infarction. With a mean follow-up time of 2.9 years, the adjusted HR for death was 1.62 (95% CI 1.28-2.03; p&lt;0.001) for each unit of increase in cystatin C on admission. The level of dynamic changes in cystatin C during admission for an acute myocardial infarction was independently associated with prognosis in patients with normal or mild impairment of renal function. The adjusted HR for death was 10.1 (95% CI 3.4-29.9; p&lt;0.001). Conclusion In patients suffering from an AMI platelet aggregation increases during the first days, despite anti-platelet treatment. Diabetes, age and biomarkers of inflammation are independently associated with platelet aggregation. Admission levels of cystatin C as well as changes in cystatin C levels during hospitalisation are independently associated with outcome.
