Factors Associated With Functional Capacity in Hemodialysis Patients.

Hemodialysis patients have a marked decrease in functional capacity when compared to healthy individuals. We evaluated the factors associated with functional capacity in hemodialysis patients. A total of 102 hemodialysis patients were evaluated. The patients were submitted to a 6-min walk test, peripheral muscle strength tests, and an evaluation of quality of life, anxiety, and depression. The laboratory data were measured. The 6-min walk test distance correlated significantly with age, educational level, hemoglobin, creatinine, number of comorbidities, peripheral muscle strength, and some domains of SF-36 quality of life questionnaire and depression (P < 0.05). Multiple linear regression showed that educational level, hemoglobin, peripheral muscle strength, and depression significantly affected the 6-min walk test distance (P < 0.05). The multiple correlation coefficient was 0.74, and the squared multiple correlation coefficient adjusted was 0.52. In conclusion, functional capacity was significantly associated with educational level, hemoglobin, peripheral muscle strength, and depression in hemodialysis patients.

Cross-sectional assessment of mild cognitive impairment in pre-dialysis chronic kidney disease and its association with inflammation and changes seen on MRI: what the eyes cannot see.

INTRODUCTION: Mild cognitive impairment (MCI) is a prevalent and underdiagnosed condition in chronic kidney disease (CKD), that shares common pathophysiological factors such as chronic inflammation. OBJECTIVE: To evaluate the association of MCI in CKD stages 1-5 using inflammatory markers and changes by magnetic resonance imaging (MRI). PATIENTS AND METHODS: Cross-sectional study in adult patients with pre-dialysis CKD. MCI was assessed by the Montreal Cognitive Assessment (MoCA) and the estimated glomerular filtration rate (eGFR) by the Chronic Kidney Disease Epidemiology Collaboration equation. Sociodemographic and clinical data were collected from medical records. The cytokines IL-4, IL-6, IL-17, TNF-α and hs-CRP were determined. Brain MRI was performed in a 1.5 Tesla device, without paramagnetic contrast. A descriptive analysis followed by a comparison of abnormal versus normal MoCA scores among all studied variables. A linear regression analysis was performed using MoCA as a dependent variable, adjusted for confounding factors. RESULTS: Of 111 invited patients, eighty completed the neuropsychological assessment and 56 underwent MRI, and were included in the study. Mean age was 56.3 ± 8.3 years and 51.8% (n = 29) had altered MoCA. When compared to the group with normal MoCA, the group with altered MoCA had higher levels of IL-6 and IL-17. There was no correlation between altered MoCA with eGFR or with MRI abnormalities. CONCLUSÃO: MCI assessed by MoCA was prevalent in patients with pre-dialysis CKD, it was associated with inflammation and showed no correlation with MRI changes.

[Cross-cultural adaptation of the PAIR instrument: Pharmacotherapy Assessment in Chronic Renal Disease for application in Brazil]. / Adaptação transcultural do instrumento PAIR: Pharmacotherapy Assessment in Chronic Renal Disease para aplicação no Brasil.

Individuals suffering from chronic kidney disease (CKD) are often on multiple medications, which exposes them to drug-related problems (DRP). There are no available tools in Brazil to assess the pharmacotherapy and management of DRPs systematically in this population. The scope of this study was to perform a cross-cultural adaptation of PAIR criteria (Pharmacotherapy Assessment in Chronic Renal Disease) to Brazilian Portuguese. PAIR criteria consist of 50 DRP clinically significant items for CKD. The process of cross-cultural adaptation involved translation, synthesis, back-translation, and an analysis by an expert committee as well as a pre-test of the first draft document. A review committee consisting of 2 pharmacists and 2 nephrologists analyzed the semantic, linguistic, experiential, and conceptual equivalence between the original and translated versions. All items that obtained a score below 80% were reviewed. Word adjustments were made, as well as the exclusion of 6 DRP due to non-applicability to the Brazilian context. Thus, the final version of PAIR defined as "Avaliação da farmacoterapia na doença renal crônica" was translated and adapted into the Brazilian Portuguese language.

Indivíduos com doença renal crônica (DRC) frequentemente utilizam polifarmácia o que os expõe ao risco de problemas relacionados a medicamentos (PRMs). No Brasil, não existem instrumentos que possam sistematizar a avaliação da farmacoterapia e a gestão de PRMs nesta população. Portanto, o objetivo deste trabalho foi realizar a adaptação transcultural do instrumento PAIR (Pharmacotherapy Assessment in Chronic Renal Disease) para o português brasileiro. O PAIR consiste numa lista de 50 PRMs considerados clinicamente significativos para renais crônicos. O processo de adaptação transcultural envolveu as etapas de tradução, síntese, retrotradução, análise por um comitê de especialistas e pré-teste da versão preliminar. O comitê de 2 farmacêuticos e 2 nefrologistas analisou a equivalência semântica, idiomática, experiencial e conceitual entre as versões original e traduzida. Todos os itens que obtiveram acordo inferior a 80% foram revisados. Foram realizados ajustes de palavras, assim como a exclusão de 6 PRMs devido à não aplicabilidade ao contexto brasileiro. Assim, foi obtida a versão final do PAIR definida como "Avaliação da farmacoterapia na doença renal crônica", traduzida e adaptada na língua portuguesa do Brasil.

Pharmacotherapy assessment in chronic kidney disease: validation of the PAIR instrument for use in Brazil.

Individuals with chronic kidney disease (CKD) use polypharmacy, which, in combination with renal impairment, exposes them to the risk of drug-related problems (DRPs). There are no available tools in Brazil to systematically assess the pharmacotherapy and management of DRPs in this population. Therefore, the objective of this work was to validate the PAIR instrument (Pharmacotherapy Assessment in Chronic Renal Disease) for use in Brazilian Portuguese. This is a retrospective longitudinal observational study. Medical records from 100 CKD patients under conservative treatment, between 2016 and 2017, in a nephrology clinic, were analyzed. PAIR was applied by pharmacists in two consultations of the same patient, with an interval of 6 months. Reliability, conceptual validity, responsiveness of the instrument and prevalence of DRPs in the studied sample were assessed. A mean of 1.26 ± 0.96 DRPs/patient was identified. Inter-rater reliability coefficients (k) ranged from 0.58 to 0.94 and from 0.79 to 1.00 for test-retest, revealing moderate to perfect level of agreement. In conceptual validity, a mean of 1.60 ± 1.24 DRPs/patient was identified by the nephrologist through clinical judgment, compared to 1.33±0.76 DRPs/patient identified by the pharmacist using PAIR (p = 0.07). Therefore PAIR allowed the identification of clinically significant DRPs. In responsiveness, a mean of 1.26 ± 0.96 DRPs/patient was identified at the first consultation and 1.11 ± 1.02 DRPs/patient at the subsequent consultation (p = 0.17) by the pharmacist using PAIR. The number of DRPs between the periods did not change. As a conclusion, the PAIR allowed the identification of clinically significant DRPs in CKD, constituting a new validated instrument to be used in Brazil.

Intradialytic resistance training: an effective and easy-to-execute strategy.

Chronic kidney disease (CKD) alters the morphology and function of skeletal muscles, thereby decreasing patient physical capacity (PC) and quality of life (QoL). Intradialytic resistance training (IRT) is a pragmatic tool used to attenuate these complications. However, IRT has not been strongly adopted in nephrology care centers. This study aimed to assess the efficacy and safety of a low-cost, easy-to-use IRT protocol. METHODS: The study enrolled 43 patients (52.8 ± 13.85 years) on HD for five to 300 months followed from April 2014 to July 2017. The efficacy of IRT was assessed based on PC - derived from muscle strength (MS) and preferred walking speed (PWS) - and QoL. The occurrence of adverse events was used as a measure of safety. The IRT protocol consisted of exercises of moderate to high intensity for the main muscle groups performed three times a week. RESULTS: The mean follow-up time was 9.3 ± 3.24 months, for a total of 4,374 sessions of IRT. Compliance to the protocol was 96.5 ± 2.90%, and patients presented significant improvements in MS (from 27.3 ± 11.58 Kgf to 34.8 ± 10.77 Kgf) and PWS (from 0.99 ± 0.29 m/s to 1.26 ± 0.22 m/s). Physical and emotional components of QoL also increased significantly. CONCLUSION: IRT led to significant increases in PC and higher scores in all domains of QoL. Important adverse events were not observed during intradialytic resistance training.

Chronic kidney disease: susceptibility in a representative population-based sample.

Chronic kidney disease has high morbidity and mortality. In order to track the disease, we conducted a population-based study in a medium-sized city in Southeastern Brazil. Based on instrument SCreening for Occult REnal Disease (SCORED), we evaluated 1,016 individuals with mean age of 44 (SD = 13.2) years. High blood pressure and diabetes mellitus, major causes of chronic kidney disease, were reported by 34.7% and 10.5% of the individuals, respectively. In addition, 31.3% of the sample presented increased risk for the disease, thus leading to a prevalence estimate of 5.4%. A simple screening method allowed the early detection of a population at risk for chronic kidney disease.

Validated registry of pre-dialysis chronic kidney disease: description of a large cohort.

INTRODUCTION: Chronic diseases account for the majority of deaths in Brazil. These include hypertension (SAH) and diabetes mellitus (DM), which are the main causes of chronic kidney disease (CKD). OBJECTIVE: This study aimed to validate the data of an electronic health record and to point out characteristics of the profile of these users in relation to clinical quality indicators for a pre-dialytic CKD. METHODS: Retrospective cohort, August/2010 to December/2014. Included users > 18 years, with at least two queries. Variables analyzed: sociodemographic, underlying disease, main medications and main clinical indicators of control. A descriptive analysis was performed and the percentage of users was evaluated in the goals at admission and at the end of the study. RESULTS: Exported, converted and validated data of 1,977 users with average follow-up time of 21 months. Of these, 51.4% were men, 58% were > 64 years of age and 81.6% were overweight. The main medications in use were diuretics (82.9%), BRAT (62%), Statin (60.7%) and ACE inhibitors (49.9%). The percentage of users with a decline in the glomerular filtration rate was 33.7%. Regarding glycated hemoglobin, users with CKD and DM, 36% were within the initial goal and 52.1% of the final. Blood pressure was at the target for admission at 34.3% and 49.8% at the end of follow-up. CONCLUSION: Validated data are of vital importance for health managers to monitor users. The population of this study is predominantly elderly, obese, requiring multi-professional care to slow the progression of the disease and decrease morbidity and mortality.

Dialogue between primary and secondary health care providers in a Brazilian hypertensive population.

OBJECTIVE: To describe clinical and epidemiological profiles of patients with hypertension referred to a secondary care unit and to assess the adequacy of the referral criteria. METHOD: This descriptive transversal study analysed 943 hypertensive patients referred to a secondary healthcare unit from September 2010 to August 2012. Clinical and sociodemographic data as well as data regarding the liaison between secondary and primary care services were collected. RESULTS: Patients' mean age was 59±13.1 years, and 61.3% were female. Sedentary lifestyle, alcohol consumption, and smoking were observed in 80.3%, 31.1%, and 18.1% of the patients, respectively. Uncontrolled blood pressure was observed in 72.5% of the sample, and 80.1% of individuals were overweight or obese. There was a high prevalence of dyslipidaemia (73.1%), cardiovascular disease (97.5%), and reduced glomerular filtration rate (49.9%). Thirty-eight percent of patients did not meet the referral criteria, of whom approximately 25% were not hypertensive. CONCLUSION: Even in a universal-access healthcare system, poor control of hypertension and high prevalence of obesity and cardiovascular diseases were observed. Inadequate referrals and the presence of clinical complications suggest low efficiency of the assistance provided in primary care and reinforce the need for sharing care with the secondary level.

Different times of day do not change heart rate variability recovery after light exercise in sedentary subjects: 24 hours Holter monitoring.

Incidence of cardiovascular events follows a circadian rhythm with peak occurrence during morning. Disturbance of autonomic control caused by exercise had raised the question of the safety in morning exercise and its recovery. Furthermore, we sought to investigate whether light aerobic exercise performed at night would increase HR and decrease HRV during sleep. Therefore, the aim of this study was to test the hypothesis that morning exercise would delay HR and HRV recovery after light aerobic exercise, additionally, we tested the impact of late night light aerobic exercise on HR and HRV during sleep in sedentary subjects. Nine sedentary healthy men (age 24 ± 3 yr; height 180 ± 5 cm; weight 79 ± 8 kg; fat 12 ± 3%; mean±SD) performed 35 min of cycling exercise, at an intensity of first anaerobic threshold, at three times of day (7 a.m., 2 p.m. and 11 p.m.). R-R intervals were recorded during exercise and during short-time (60 min) and long-time recovery (24 hours) after cycling exercise. Exercise evoked increase in HR and decrease in HRV, and different times of day did not change the magnitude (p < 0.05 for time). Morning exercise did not delay exercise recovery, HR was similar to rest after 15 minutes recovery and HRV was similar to rest after 30 minutes recovery at morning, afternoon, and night. Low frequency power (LF) in normalized unites (n.u.) decreased during recovery when compared to exercise, but was still above resting values after 60 minutes of recovery. High frequency power (HF-n.u.) increased after exercise cessation (p < 0.05 for time) and was still below resting values after 60 minutes of recovery. The LF/HF ratio decreased after exercise cessation (p < 0.05 for time), but was still different to baseline levels after 60 minutes of recovery. In conclusion, morning exercise did not delay HR and HRV recovery after light aerobic cycling exercise in sedentary subjects. Additionally, exercise performed in the night did change autonomic control during the sleep. So, it seems that sedentary subjects can engage physical activity at any time of day without higher risk.

Abstract Introduction: Mild cognitive impairment (MCI) is a prevalent and underdiagnosed condition in chronic kidney disease (CKD), that shares common pathophysiological factors such as chronic inflammation. Objective: To evaluate the association of MCI in CKD stages 1-5 using inflammatory markers and changes by magnetic resonance imaging (MRI). Patients and Methods: Cross-sectional study in adult patients with pre-dialysis CKD. MCI was assessed by the Montreal Cognitive Assessment (MoCA) and the estimated glomerular filtration rate (eGFR) by the Chronic Kidney Disease Epidemiology Collaboration equation. Sociodemographic and clinical data were collected from medical records. The cytokines IL-4, IL-6, IL-17, TNF-α and hs-CRP were determined. Brain MRI was performed in a 1.5 Tesla device, without paramagnetic contrast. A descriptive analysis followed by a comparison of abnormal versus normal MoCA scores among all studied variables. A linear regression analysis was performed using MoCA as a dependent variable, adjusted for confounding factors. Results: Of 111 invited patients, eighty completed the neuropsychological assessment and 56 underwent MRI, and were included in the study. Mean age was 56.3 ± 8.3 years and 51.8% (n = 29) had altered MoCA. When compared to the group with normal MoCA, the group with altered MoCA had higher levels of IL-6 and IL-17. There was no correlation between altered MoCA with eGFR or with MRI abnormalities. Conclusão: MCI assessed by MoCA was prevalent in patients with pre-dialysis CKD, it was associated with inflammation and showed no correlation with MRI changes.

Resumo Introdução: O comprometimento cognitivo leve (CCL) é prevalente e subdiagnosticado na doença renal crônica (DRC), condição com a qual compartilha fatores fisiopatológicos como a inflamação crônica. Objetivo: Avaliar a associação do CCL na DRC estágios 1 a 5, com marcadores inflamatórios e alterações de exames de imagem por ressonância magnética (RM). Pacientes e métodos: Estudo transversal em pacientes adultos, com DRC pré-dialítica. CCL foi avaliado pelo Montreal Cognitive Assessment (MoCA) e a taxa de filtração glomerular estimada (TFGe), pela equação do CKD-EPI. Dados sociodemográficos e clínicos foram coletados nos prontuários médicos. Dosadas citocinas IL-4, IL-6, IL-17, o TNF-α e PCR-us. A RM do encéfalo foi realizada em aparelho de 1,5 Tesla, sem contraste. Realizada análise descritiva seguida por comparação de pontuações do MoCA anormais versus normais entre todas as variáveis estudadas. A regressão linear foi realizada usando MoCA como uma variável dependente, ajustada para fatores de confusão. Resultados: De 111 pacientes convidados, oitenta completaram a avaliação neuropsicológica, 56 realizaram RM, tendo sido incluídos no estudo. A média de idade foi de 56,3 ± 8,3 anos e 51,8% (n = 29) apresentavam MoCA alterado. Quando comparado ao grupo MoCA normal, o grupo MoCA alterado apresentou níveis mais elevados de IL-6 e IL-17. Não houve correlação entre MoCA alterado com TFGe nem com anormalidades na RM. Nos modelos ajustados, a IL-6 foi preditor independente do MoCA alterado Conclusão: O CCL avaliado pelo MoCA foi prevalente em pacientes com DRC pré-dialítica, associou-se com inflamação e não apresentou correlação com alterações da RM.

Strengths of primary healthcare regarding care provided for chronic kidney disease.

OBJECTIVE: to assess the structure and results obtained by the "Chronic Renal Patients Care Program" in a Brazilian city. METHOD: epidemiological, cross-sectional study conducted in 14 PHC units and a secondary center from 2010 to 2013. The Donabedian Model was the methodological framework used. A total of 14 physicians, 13 supervisors, and 11 community health agents from primary healthcare were interviewed for the assessment of structure and process and 1,534 medical files from primary healthcare and 282 from secondary care were consulted to assess outcomes. RESULTS: most units lacked sufficient offices for physicians and nurses to provide consultations, had incomplete staffing, and most professionals had not received proper qualification to provide care for chronic renal disease. Physicians from PHC units classified as capable more frequently referred patients to the secondary care service in the early stages of chronic renal disease (stage 3B) when compared to physicians of units considered not capable (58% vs. 36%) (p=0.049). Capable PHC units also more frequently presented stabilized glomerular filtration rates (51%) when compared to partially capable units (36%) and not capable units (44%) (p=0.046). CONCLUSION: patients cared for by primary healthcare units that scored higher in structure and process criteria presented better clinical outcomes. OBJECTIVE: to identify the coping strategies of family members of patients with mental disorders and relate them to family member sociodemographic variables and to the patient's clinical variables. METHOD: this was a descriptive study conducted at a psychiatric hospital in the interior of the state of São Paulo, with 40 family members of hospitalized patients over the age of 18, and who followed the patient before and during hospitalization. We used tools to characterize the subjects and the Folkman and Lazarus Inventory of Coping Strategies. RESULTS: the coping strategies most often used by family members were social support and problem solving. Mothers and fathers used more functional strategies (self-control p=0.037, positive reappraisal p=0.037, and social support p=0,021). We found no significant differences between the strategies and other variables examined. CONCLUSION: despite the suffering resulting from the illness of a dear one, family members make more use of functional strategies, allowing them to cope with adversities in a more well-adjusted way. OBJETIVO: avaliar estrutura, processo e resultado do "Programa de Atenção a Doentes Renais Crônicos" em um município brasileiro. MÉTODO: estudo epidemiológico, transversal, realizado em 14 unidades de atenção primária e um centro de atenção secundária, no período de 2010-2013. Utilizou-se o referencial metodológico de Donabedian. Para avaliação de estrutura e processo, foram entrevistados 14 médicos, 13 supervisores e 11 agentes comunitários de saúde da atenção primária. Para avaliação de resultado, foram utilizados 1.534 prontuários de saúde na atenção primária e 282 na atenção secundária. RESULTADOS: na maioria das unidades faltam consultórios para atendimento médico e de enfermagem, as equipes estavam incompletas e a maioria dos profissionais não participou de capacitação para atenção à doença renal crônica. Médicos das unidades primárias, classificadas como capacitadas, encaminharam usuários à atenção secundária em estágios mais precoces da doença renal crônica (estágio 3B) quando comparados aos médicos das unidades não capacitadas (58% vs 36%) (p=0,049). As unidades de atenção primária, classificadas como capacitadas, apresentaram melhores taxas de estabilização da filtração glomerular (51%) quando comparadas às unidades parcialmente capacitadas (36%) e não capacitadas (44%) (p=0,046). CONCLUSÃO: usuários atendidos nas unidades de atenção primária com pontuação mais elevada em critérios de estrutura e processo apresentaram melhores resultados clínicos.

Important adverse events were not observed during intradialytic resistance training.

Resumo A doença renal crônica (DRC) promove alterações morfofuncionais dos músculos esqueléticos, gerando redução da capacidade físico-funcional (CF) e pior qualidade de vida (QV). O treinamento resistido intradialítico (TRI) é considerado uma ação pragmática para atenuar tais complicações. Contudo, nota-se baixa inserção do TRI nos centros de tratamento em nefrologia. O objetivo deste estudo foi avaliar a eficácia e a segurança de uma proposta metodológica de TRI de fácil execução e de baixo custo. Métodos: 43 pacientes (52,8±13,85 anos), com tempo em HD entre cinco e 300 meses, foram acompanhados entre abril de 2014 e julho de 2017. A eficácia do TRI foi mensurada pela CF, avaliada pela força muscular (FM) e pela velocidade de caminhada usual (VCU) e pela QV. Como critério de segurança adotou-se a ocorrência de intercorrências clínicas. O protocolo de TRI consistiu em exercícios de moderada a alta intensidade para os principais grupos musculares, realizados três vezes por semana. Resultados: o tempo médio de acompanhamento foi de 9,3 ± 3,24 meses, totalizando 4.374 sessões de TRI. A aderência ao protocolo foi de 96,5 ± 2,90, e os pacientes apresentaram melhora significativa da FM (de 27,3±11,58 Kgf para 34,8±10,77 Kgf) e da VCU (de 0,99 ± 0,29 m/s para 1,26 ± 0,22 m/s). Quanto à QV, tanto os domínios do componente físico quanto do emocional aumentaram significativamente. Conclusão: o TRI promoveu aumento significativo da CF e melhora de todos os domínios da QV, e não foram observadas intercorrências importantes com a realização dos exercícios intradialíticos.

Efeito da prática regular de atividade física na qualidade de vida relacionada à saúde de hipertensos resistentes / Effect of regular physical activity on health-related quality of life of resistant hypertensive patients

Introdução: Hipertensos resistentes apresentam pior qualidade de vida relacionada à saúde em relação aos pacientes com hipertensão arterial sistêmica. A prática regular de exercícios físicos melhora essa qualidade de vida de pacientes com hipertensão arterial sistêmica. Assim, é possível que a atividade física melhore a qualidade de vida relacionada à saúde dos hipertensos resistentes. Objetivo: Avaliar os efeitos da prática regular de atividade física na qualidade de vida relacionada à saúde de pacientes com hipertensão arterial resistente. Material e Métodos: Foram avaliados 38 pacientes, de ambos os gêneros, diagnosticados com hipertensão arterial resistente, divididos nos grupos ativo (n=19, 64±7 anos) e sedentário (n=19, 56±10 anos). Foi considerado fisicamente ativo o paciente que praticava exercício físico por pelo menos três vezes por semana, com duração mínima de duas horas semanais, por período superior a quatro meses. Foi utilizado o teste t de Student para amostras independentes, com nível de significância de p<0,05. Resultados: A qualidade de vida relacionada à saúde foi significativamente maior no grupo Ativo em relação ao grupo Sedentário para os domínios capacidade funcional (69±25 vs. 44±22 pontos, p<0,01), dor (66±23 vs. 49±22 pontos, p=0,03), estado geral de saúde (61±16 vs. 52±9 pontos, p=0,03), vitalidade (69±20 vs. 43±22 pontos, p<0,01), limitação por aspectos físicos (75±38 vs. 40±34 pontos, p<0,01) e saúde mental (76±24 vs. 53±26 pontos, p=0,01), respectivamente. Os grupos Ativo e Sedentário foram semelhantes para os domínios aspectos sociais (74±24 vs. 68±28 pontos, p=0,54) e limitação por aspectos emocionais (63±38 vs. 40±36 pontos, p=0,07), respectivamente. Conclusão: A prática regular de atividade física parece melhorar a qualidade de vida relacionada à saúde de hipertensos resistentes.

Introduction: Resistant hypertensive patients have worse health-related quality of life than patients with systemic arterial hypertension. Regular exercise improves this quality of life of patients with systemic arterial hypertension. Thus, it is possible that physical activity increases the health-related quality of life of resistant hypertensive patients. Objective: To test the hypothesis that regular physical activity improves the health-related quality of life of patients with resistant hypertension. Material and methods: Were evaluated 38 patients, male and famale, diagnosed with resistant hypertension, divided into Active (n=19, 64±7 years old) and Sedentary (n=19, 56±10 years old) groups. The patient who was physically active for at least three times a week, with a minimum duration of two hours per week for more than four months, was considered physically active. And, considered sedentary, the patient who had not practiced exercise regularly for at least six months. Student's t test for independent samples was used and considered significant p <0.05. Results: Health-related quality of life was significantly higher in the Active group compared to the Sedentary group for the domains functional capacity (69±25 vs. 44±22 points, p<0.01), pain (66±23 vs. 49±22 points, p=0.03), general health (61±16 vs. 52±9 points, p=0.03), vitality (69±20 vs. 43±22 points, p<0.01), limitation by physical aspects (75±38 vs. 40±34 points, p<0.01) and mental health (76±24 vs. 53±26 points, p=0.01), respectively. And, the Active and Sedentary groups were similar for the domains social aspects (74±24 vs. 68±28 points, p=0.54) and limitation by emotional aspects (63±38 vs. 40±36 points, p=0.07), respectively. Conclusion: Regular physical activity improves the health-related quality of life of patients with resistant hypertension.

Baixo letramento em saúde em pacientes idosos com pressão arterial não controlada em nível secundário de atenção à saúde / Low health literacy in older patients with uncontrolled blood pres-sure at secondary care

Introdução: O baixo letramento em saúde (BLS) é comum entre pacientes com doenças crônicas. Os estudos sobre a associação entre o BLS e a pressão arterial não controlada estão limitados aos níveis primário e terciário de atenção à saúde. Objetivo: Avaliamos a prevalência e a associação entre BLS e pressão arterial não controlada em pacientes hipertensos em um centro de atenção secundária à saúde no Brasil. Material e métodos: Nosso estudo teve delineamento transversal e incluiu 485 pacientes, no período de Agosto/2014 a Março/2016. Avaliamos letramento em saúde, pelo Short Assessment of Health Literacy for Portuguese-Speaking Adults (SAHLPA-18), e controle pressórico. Indivíduos com um escore ≤14 em SAHLPA-18 foram considerados com BLS, e indivíduos com pressão arterial ≥140/90 (ou ≥130/80 em pacientes diabéticos) foram considerados como tendo pressão arterial não controlada. Resultados:Um total de 56,0% eram mulheres, com média de idade de 62,0±12,6 anos. Os participantes analfabetos eram 61,6% e 65,4% recebiam até um salário mínimo. Tanto a pressão arterial não controlada quanto o BLS foram muito prevalentes (75,1% e 70,9%, respectivamente), entretanto não houve associação entre esses dois parâmetros. Na análise multivariada, a pressão arterial não controlada foi associada à idade (OR:0,96, IC:0,94-0,98, p<0,001), diabetes mellitus (OR:4,36, IC:2,54-7,51; p<0,001) e número de comprimidos (OR:1,16, Cl:1,08-1,25, p<0,001). Conclusão: Mesmo encontrando alta prevalência de BLS, a falta de associação entre BLS e pressão arterial não controlada pode ser devido às características demográficas da amostra, ou seja, idosos com baixa renda e baixa escolaridade. A avaliação do letramento em saúde fornece informações importantes que apoiam ações para melhorar o controle e o tratamento da hipertensão.

Background: Low health literacy (LHL) is common among patients with chronic diseases. Studies on the association between LHL and uncontrolled blood pressure are limited to primary and tertiary levels of healthcare. Objective:We evaluated the prevalence and association between LHL and uncontrolled blood pressure in hypertensive patients in a secondary healthcare in Brazil. Material and methods: Our study had a cross-sectional design and included 485 patients, between August/2014 to March/2016. We evaluated health literacy, by Short Assessment of Health Literacy for Portuguese-Speaking Adults (SAHLPA-18), and the blood pressure control. Individuals with a score ≤14 in SAHLPA-18 were considered as LHL, and individuals with blood pressure ≥140/90 (or ≥130/80 in diabetic patients) were considered as having uncontrolled blood pressure. Results: A total of 56.0% female, with mean age 62.0±12.6 years. Illiterate participants were 61.6%, and 65.4% earned up to one reference wage. Both uncontrolled blood pressure and LHL were highly prevalent (75.1% and 70.9%, respectively), but there was no association between these two parameters. In multivariate analysis, uncontrolled blood pressure was associated with age (OR:0.96, CI:0.94-0.98, p<0.001), diabetes mellitus (OR:4.36, CI:2.54-7.51; p<0.001) and number of pills (OR:1.16, CI:1.08-1.25, p<0.001). Conclusion: Even we found a high prevalence of LHL, the lack of association between LHL and uncontrolled blood pressure may be due to demographic characteristics of the sample, i.e., elderly people with low income and low schooling. HL assessment provides important information that supports actions to improve hypertension control and treatment.

Chronic kidney disease: susceptibility in a representative population-based sample / Doença renal crônica: suscetibilidade em uma amostra representativa de base populacional

ABSTRACT Chronic kidney disease has high morbidity and mortality. In order to track the disease, we conducted a population-based study in a medium-sized city in Southeastern Brazil. Based on instrument SCreening for Occult REnal Disease (SCORED), we evaluated 1,016 individuals with mean age of 44 (SD = 13.2) years. High blood pressure and diabetes mellitus, major causes of chronic kidney disease, were reported by 34.7% and 10.5% of the individuals, respectively. In addition, 31.3% of the sample presented increased risk for the disease, thus leading to a prevalence estimate of 5.4%. A simple screening method allowed the early detection of a population at risk for chronic kidney disease.

Validated registry of pre-dialysis chronic kidney disease: description of a large cohort / Registro validado de doença renal crônica pré-dialítica: descrição de uma grande coorte

ABSTRACT Introduction: Chronic diseases account for the majority of deaths in Brazil. These include hypertension (SAH) and diabetes mellitus (DM), which are the main causes of chronic kidney disease (CKD). Objective: This study aimed to validate the data of an electronic health record and to point out characteristics of the profile of these users in relation to clinical quality indicators for a pre-dialytic CKD. Methods: Retrospective cohort, August/2010 to December/2014. Included users > 18 years, with at least two queries. Variables analyzed: sociodemographic, underlying disease, main medications and main clinical indicators of control. A descriptive analysis was performed and the percentage of users was evaluated in the goals at admission and at the end of the study. Results: Exported, converted and validated data of 1,977 users with average follow-up time of 21 months. Of these, 51.4% were men, 58% were > 64 years of age and 81.6% were overweight. The main medications in use were diuretics (82.9%), BRAT (62%), Statin (60.7%) and ACE inhibitors (49.9%). The percentage of users with a decline in the glomerular filtration rate was 33.7%. Regarding glycated hemoglobin, users with CKD and DM, 36% were within the initial goal and 52.1% of the final. Blood pressure was at the target for admission at 34.3% and 49.8% at the end of follow-up. Conclusion: Validated data are of vital importance for health managers to monitor users. The population of this study is predominantly elderly, obese, requiring multi-professional care to slow the progression of the disease and decrease morbidity and mortality.

Determinação do estado nutricional: qual o valor de peso e altura autorreferidos? / Determination of nutritional state: what is the value of weight and height self-reported?

Introdução: Altas prevalências de sobrepeso e obesidade são descritas em diferentes populações. No entanto, grande parcela da população tem percepções imprecisas sobre seu peso corporal e, consequentemente, sobre a classificação nutricional. Objetivo: Comparar a percepção autorreferida do peso corporal frente à classificação nutricional baseada na aferição realizada por profissional de saúde em amostra representativa da população de cidade de grande porte do sudeste brasileiro. Material e métodos: Foi realizado estudo transversal por inquérito populacional em cidade de médio porte do sudeste brasileiro, sendo a coleta de dados realizada de junho/2014 a abril/2016. Utilizou-se amostragem domiciliar em três estágios e aproximadamente 4.800 domicílios foram visitados, a partir dos quais, 1.032 participantes foram aleatoriamente selecionados e incluídos na pesquisa. Resultados: A média de idade dos participantes foi de 44±13,2 anos, sendo 53,2% indivíduos do sexo feminino. Com base no autorrelato de peso e altura e cálculo do índice de massa corporal (IMC), observou-se que 58,7% da população se encontravam com excesso de peso. Dos 521 indivíduos que foi possível realizar a avaliação do peso e altura por profissionais de saúde vimos que ao se comparar a classificação nutricional baseada no autorrelato com aquela obtida a partir de dados mensurados pelos profissionais, observou-se que o número de casos de obesidade foi 7,1% maior. Conclusão: Diante dos dados do presente estudo, a autopercepção do excesso de peso pode não ser adequada como ferramenta para avaliação de populações em risco para obesidade/sobrepeso, além disso, os resultados reforçam a necessidade de educação sobre o uso do IMC assim como da importância das orientações por profissionais de saúde.

Introduction: High prevalences of overweight and obesity are described in different populations. However, a large portion of the population has inaccurate perceptions about their body weight and, consequently, about nutritional classification. Objective: To compare the self - reported perception of body weight versus nutritional classification based on the measurement performed by a health professional, in a representative sample of the population of a large city in southeastern Brazil. Material andMethods: A cross - sectional study was conducted by a population survey in a medium - sized city in southeastern Brazil. Data collection was performed from June 2014 to April 2016. Household sampling was used in three stages and approximately 4,800 households were visited, from which 1,032 participants were randomly selected and included in the study. Results: The mean age of participants was 44 ± 13.2 years, of which 53.2% were female. Based on self-report of weight and height and calculation of body mass index (BMI), it was observed that 58.7% of the population were overweight. Of the 521 individuals who were able to perform weight and height assessment by health professionals, we observed that when comparing the nutritional classification based on self-report and that obtained from data measured by professionals, it was observed that the number of cases of obesity was 7.1% higher. Conclusion: Considering the data of the present study, the self-perception of excess weight may not be adequate as a tool for the evaluation of populations at risk for obesity/overweight, in addition, the results reinforce the need for education about BMI use as well as importance of the guidelines by health professionals.

Obesidade e doença renal: aspectos fisiopatológicos / Obesity and kidney disease: pathophysiological aspects

A epidemia de obesidade observada nas últimas décadas é acompanhada de aumento exponencial de doenças crônicas relacionadas, com destaque diabetes mellitus tipo 2, hipertensão arterial sistêmica, dislipidemia e doenças cardiovasculares. Do mesmo modo, a obesidade constitui fator de risco independente para o desenvolvimento de doença renal crônica, condição associada a elevados índices de morbidade e de mortalidade. A obesidade causa lesão renal de maneira indireta, por meio de sua estreita associação com hipertensão arterial sistêmica e com diabetes mellitus tipo 2 e de maneira direta, ao induzir adaptações glomerulares que culminam na glomerulopatia específica da obesidade. Além disso, o excesso de peso contribui para o agravamento de glomerulopatias pré-existentes. Múltiplos fatores explicam o desenvolvimento e o agravamento das lesões renais associadas à obesidade, em especial alterações hemodinâmicas, inflamatórias e metabólicas. Nesse contexto, a redução do peso corporal com ênfase nas alterações metabólicas e inflamatórias bem como o tratamento da hipertensão arterial e do diabetes mellitus constituem o primeiro passo para a prevenção primária e secundária do desenvolvimento de doença renal crônica. Nesta revisão serão apresentados os principais mecanismos fisiopatológicos da lesão renal associada à obesidade.

n the last decades, the obese epidemic has been accompanied by an exponential increase in the prevalence of chronic conditions such as type 2 diabetes, hypertension, dyslipidemia, and other forms of cardiovascular disease. Moreover, obesity is an independent risk factor for the development of chronic kidney disease, itself a condition associated with high risk of morbidity and mortality. Obesity can cause chronic kidney disease both indirectly, as a major risk factor for diabetes and hypertension, and directly, through adaptive glomerular changes that evolve into a specific form of glomerulopathy. Furthermore, excessive weight can worsen other forms of pre-existent glomerular diseases. Multiple factors can explain the development and worsening of renal lesions associated with obesity, mainly through hemodynamic, inflammatory and metabolic changes. In this context, reduction of body weight with emphasis on metabolic and inflammatory changes, as well as the treatment of hypertension and diabetes, constitute the first step towards primary and secondary prevention against development of chronic kidney disease. This review presents the physiopathology of the obesity related glomerulopathy.
