Avaliação funcional pré e pós programa de exercício físico de pacientes em hemodialise

Model Study: An experimental study Introduction: Chronic Kidney Disease (CKD) refers to a syndromic diagnosis which leads to a progressive and irreversible loss of renal function. A hemodialysis patient may have limitations in functional capacity, pulmonary function and respiratory musclular strength impacting in quality of life. Objective: To evaluate the effects of an exercise program on pulmonary function, functional capacity, quality of life and pain in patients undergoing hemodialysis. Methodology: The study included 28 patients of both genders, women and men aged between 40 and 60 years undergoing dialysis at the Kidney Institute, Santa Casa de Misericordia in Presidente Prudente-SP. Primary outcomes included respiratory muscular strength measurements assessed by manovacuometry. The functional capacity was evaluated by a six minute walking test. A life quality questionnaire was applied to evaluate quality of life (SF36-KDQOL). Lung function was evaluated by spirometry. Pain was assessed by a visual analogue scale. The exercise program consisted of training 3 times a week for 40 minutes on hemodialysis during eight weeks. At the end of the program all patients were reassessed. Results: There was no significant difference in the values of FVC and FEV1 before and after the exercise program as well as the index Tiffenau. The value of post MIP was significantly higher than the value obtained in the pre program. For variable MEP no significant difference was found. Functional capacity evaluations showed that there were no significant differences (p> 0.05). The evaluation of quality of life, about the domains of specific areas of CKD showed statistical significance when comparing the list of symptoms and problems with overloading of renal disease and professional role. Indicators related to pain were significantly reduced after the program (P <0.05). Discussion: A chronic kidney patient faces complex situations of physical, social and financial aspects. Although no statistically significant results were found in all variables, the study corroborates to others found in the literature, which suggests that an exercise program can be positive for this population. Conclusion: Although lung capacity and functional capacity did not submit changes to the end of the study, reduced levels of pain, fatigue and dyspnea suggest improvement in functional performance after exercise programs.

Prevention of Intradialytic Hypotension in Patients with Acute Kidney Injury Submitted to Sustained Low-Efficiency Dialysis

Objectives: This study evaluated the effects of a protocol aiming to reduce hypotension in acute kidney injury (AKI) patients submitted to sustained low-efficiency dialysis (SLED). Methods: Patients were randomly assigned to two SLED prescriptions-control group, dialysate temperature was 37.0 degrees C with a fixed sodium concentration [138 mEq/L] and ultrafiltration (UF) rate; and profiling group, dialysate temperature was 35.5 degrees C with a variable sodium concentration [150-138 mEq/L] and UF rate. Results: Sixty-two SLED sessions were evaluated (34 in profiling and 28 in control). Patients (n = 31) were similar in terms of gender, age, and Sequential Organ Failure Assessment (SOFA) score. Dialysis time, dialysis dose, and post-dialysis serum sodium were similar in both groups. The profiling group had significantly less hypotension episodes (23% vs. 57% in control, p = 0.009) and achieved higher UF volume (2.23 +/- 1.25 L vs. 1.59 +/- 1.03 L in control, p = 0.04) when compared with control group. Conclusions: SLED protocol with modulation of dialysate temperature, sodium, and UF profiling showed similar efficacy but less intradialytic hypotension when compared with a standard SLED prescription.

Functional independence in patients with chronic kidney disease being treated with haemodialysis

Purpose: This study has described and analysed the functional independence of the patients served in the haemodialysis services of a countryside town in the State of Sao Paulo, Brazil, using the Functional Independence Measure (FIM). Method: The population considered was that of 214 patients being treated with haemodialysis, assessed in 2011, by means of a social, demographic and clinical report, a Mini-Mental State Examination (MMSE) and also the FIM. Results: The mean age of the population under study was 58.01 years, while the mean FIM point score was 118.38 points, showing a level of complete or modified independence within this population. Even though the level of dependence found has been low, this can be highlighted, within the locomotion domain, in the activity of going up and down stairs (10.28%). Age, complications arising from haemodialysis, and comorbidities show a negative correlation with FIM. Conclusion: Awareness of the level of functional independence of the patients being subjected to treatment with haemodialysis is essential in order to back up intervention for the improvement of nursing assistance provided to this population.

Redução da densidade de extrassístoles e dos sintomas relacionados após administração de magnésio por via oral

FUNDAMENTO: As extrassístoles ventriculares e supraventriculares (EV e ESSV) são frequentes e muitas vezes sintomáticas. O íon magnésio (Mg) desempenha um papel importante na fisiologia do potencial de ação transmembrana celular e do ritmo cardíaco. OBJETIVO: Avaliar se a administração do pidolato de magnésio (PMg) em pacientes com EV e ESSV tem desempenho superior ao uso do placebo (P) na melhora dos sintomas e densidade das extrassístoles (DES). MÉTODOS: Estudo duplo-cego, randomizado, com 60 pacientes sintomáticos consecutivos, com mais de 240/EV ou ESSV ao Holter de 24 horas e selecionados para receber P ou PMg. Para avaliar a melhora da sintomatologia, foi feito um questionário categórico e específico de sintomas relacionados às extrassístoles. Após o tratamento, foi considerada significante uma redução de mais de 70% na DES por hora. A dose do PMg foi de 3,0 g/dia por 30 dias, equivalente a 260 mg do elemento Mg. Nenhum paciente tinha cardiopatia estrutural ou insuficiência renal. RESULTADOS: Dos 60 pacientes estudados, 33 eram do sexo feminino (55%). A faixa etária variou de 16 a 70 anos. No grupo PMg, 76,6% dos pacientes tiveram redução maior que 70%, 10% deles maior que 50% e somente 13,4% tiveram redução menor que 50% na DES. No grupo P, 40% dos pacientes tiveram melhora de apenas 30% na frequência de extrassístoles (p < 0,001). A melhora dos sintomas foi alcançada em 93,3% dos pacientes do grupo PMg, comparada com somente 16,7% do grupo P (p < 0,001). CONCLUSÃO: A suplementação de Mg via oral reduziu a DES, resultando em melhora dos sintomas.

Uso a longo prazo de enalapril e hidroclorotiazida em dois pacientes com novas mutações com doença de Dent tipo 1

A doença de Dent é uma tubulopatia ligada ao X causada por mutações no gene que codifica o canal de cloro CLCN-5 e é caracterizada por proteinúria de baixo peso molecular, hipercalciúria, nefrocalcinose e insuficiência renal. Vários casos têm sido descritos, nos quais o único sintoma na apresentação foi proteinúria assintomática e glomerulosclerose global ou segmentar. A insuficiência renal nesses pacientes pode ser causada pela hipercalciúria e proteinúria persistente. Portanto, o inibidor da enzima de conversão da angiotensina e os tiazídicos poderiam ser úteis. O objetivo desta pesquisa é relatar os efeitos destas drogas em dois pacientes com doença de Dent tipo 1 com mutações novas. Neste relato não foram observadas correlações significativas entre dose de hidroclorotiazida e calciúria e entre enalapril e proteinúria. Este achado é importante, pois, sendo pacientes poliúricos, o uso destas drogas poderia prejudicar a função renal

Liver transplant outcome: a comparison between high and low MELD score recipients

OBJECTIVE: To compare low and high MELD scores and investigate whether existing renal dysfunction has an effect on transplant outcome. METHODS: Data was prospectively collected among 237 liver transplants (216 patients) between March 2003 and March 2009. Patients with cirrhotic disease submitted to transplantation were divided into three groups: MELD > 30, MELD < 30, and hepatocellular carcinoma. Renal failure was defined as a ± 25% decline in estimated glomerular filtration rate as observed 1 week after the transplant. Median MELD scores were 35, 21, and 13 for groups MELD > 30, MELD < 30, and hepatocellular carcinoma, respectively. RESULTS: Recipients with MELD > 30 had more days in Intensive Care Unit, longer hospital stay, and received more blood product transfusions. Moreover, their renal function improved after liver transplant. All other groups presented with impairment of renal function. Mortality was similar in all groups, but renal function was the most important variable associated with morbidity and length of hospital stay. CONCLUSION: High MELD score recipients had an improvement in the glomerular filtration rate after 1 week of liver transplantation.

História oral de vida de pessoas com úlcera venosa nos serviços de atenção primária à saúde

The Chronic Venous insufficiency is characterized as a set of physical changes including how most serious complication of venous ulcers, characterized by irregular and progressive loss of continuity of the skin. The occurrence of venous ulcers in people with chronic venous insufficiency generates dependence on them with health services, with long-term treatments that cause limitations and high-impact changes, affecting their quality of life, affecting the physical, psychological, social, cultural and spiritual as an important public health problem. This study aimed to describe the experience of having a venous ulcer, in the scenario of primary health care services to Health, which includes Primary Care Units and Family Health Strategy in the city of Natal / RN, based on the life histories of users. This is a qualitative study, exploratory and descriptive, with the Oral History of Life as a methodological framework. From the ponto zero was the recruitment of participants who formed the network, totaling six employees, of both sexes and aged between 57 and 79 years. After approval by the Research Ethics Committee - UFRN under the Protocol 653 788/2014 and CAAE 30408014.0.0000.5537 was held data collection, between the months of July and August, through interviews, using identification and characterization of the instrument employees and open questions. Interviews were recorded, transcribed, transcriadas and returned to employees for a conference. The narratives were subjected to Content thematic analysis technique, according to Bardin, allowing the construction of three themes that encompass categories, namely: Axis I - Perspectives on the changes: the impact wound in social relations (changes with ulcer venous, venous ulcer and social and family relationships); Axis II - Brands in body and soul: the story of being hurt (conceptions of the body injured; therapeutic itinerary in primary care services); and Axis III - Reconstruction of being hurt: coping mechanisms (redefinition of the wounded body, resilience to chronic wound). The impact of having a chronic venous ulcer generates impact of physical, psychological and social order. As aspects related to changes after the appearance of venous ulcers, survey participants reported the presence of pain, physical limitations, psychological distress, social and emotional isolation, incapacity, aesthetic discomfort and dependency on health services; the family was the aspect thatshowed no significant change after the occurrence of wound for most participants, an ally in the therapeutic process as a support network. The redefinition of the body and the wound are the main coping mechanism of chronic condition. The services in the Primary Care Network play a fundamental role in the rehabilitation of patients with venous ulcers, although there are difficulties in accessing appropriate treatment and need for expanded services, with permanent professional training of health teams and providing the resources managers to strengthen the comprehensive care of people with venous ulcers in Health Primary Care.

Efeitos do treino resistido na capacidade funcional e na reatividade pressórica em pacientes intradialíticos

Pacientes com doença renal crônica (DRC) submetidos ao treinamento resistido durante a hemodiálise apresentam benefícios substanciais dos sistemas muscular e cardiovascular, da capacidade funcional e da sua qualidade de vida. Entretanto, as melhorias na reatividade pressórica ainda não estão bem esclarecidas. O objetivo foi analisar o efeito do treino resistido na melhora da capacidade funcional e da reatividade pressórica em pacientes hemodialisados, em Natal/RN no ano de 2014. Trata-se de um ensaio clínico controlado e randomizado, com amostra de 64 pacientes, com média de idade de 42,28 (±11,48) anos, distribuídos em grupo experimental (GE) e controle (GC). Para mensurar os ganhos de força de membros inferiores foram utilizados os testes de sentar e levantar e de levantar e caminhar, já para a reatividade pressórica o teste cold pressor, em ambos os grupos antes e após a intervenção. Além disso, apenas o GE participou do treinamento resistido durante a hemodiálise em 16 semanas, composto por 3 sessões semanais, 3 séries de 10 repetições máximas (RM) estimadas (para extensores de joelho e flexores de quadril e joelho), entre 50 a 70% de 10 RM. Para a intensidade do treinamento foi utilizada a escala de Borg entre 11 a 14 durante as seções. Os dados foram analisados utilizando o Teste t para amostras independentes (inter-grupos) bem como para comparar a diferença das médias nos grupos pré e pós-intervenção (intra-grupos) a partir do Teste t para amostras repetidas. Para todas as variáveis foi considerada a significância estatística de 5% executados no software SPSS® 20.0. O estudo foi aprovado pelo comitê de ética do Hospital Universitário Onofre Lopes (HUOL - UFRN) número 37992214.2.0000.5292. Após a intervenção, verificou-se que os pacientes do GE tiveram um desempenho melhor nos testes de força (p<0,001) em comparação ao GC. Resultado também observado na pressão arterial sistólica e diastólica (PAS e PAD) ambas de repouso que apresentaram redução dos níveis pressóricos apenas no GE (p<0,001). Na reatividade pressórica tanto nos períodos pré bem como após 2 minutos também demonstraram reduções estatisticamente significativas do GE (p<0,001 e p=0,012) respectivamente quando comparado ao GC. Conclui-se que o treinamento resistido melhorou desempenho nos testes de força de membros inferiores beneficiando a capacidade funcional dos pacientes em hemodiálise, como também a pressão arterial de repouso e os níveis de reatividade pressórica obtiveram reduções significativas de seus valores após a intervenção. Além disso, este tipo de treinamento também pode ser utilizado como uma estratégia de proteção aos fatores de risco cardiovascular em pacientes renais crônicos.
