Progression of valve heart disease in a cohort of patients undergoing renal replacement therapy / Progressão da doença cardíaca valvar em coorte de doentes em terapia renal substitutiva

Abstract Introduction: Cardiovascular disease is an important cause of death among patients with chronic kidney disease (CKD). Valve calcification is a predictor of cardiovascular mortality and coronary artery disease. Objective: To assess heart valve disease frequency, associated factors, and progression in CKD patients. Methods: We conducted a retrospective study on 291 CKD patients at Hospital das Clínicas de Pernambuco. Inclusion criteria were age ≥ 18 with CKD and valve disease, while those on conservative management or with missing data were excluded. Clinical and laboratory variables were compared, and patients were categorized by dialysis duration (<5 years; 5-10 years; >10 years). Statistical tests, including chi-square, Fisher's exact, ANOVA, and Kruskal-Wallis, were employed as needed. Simple and multivariate binary regression models were used to analyze valve disease associations with dialysis duration. Significance was defined as p < 0.05. Results: Mitral valve disease was present in 82.5% (240) of patients, followed by aortic valve disease (65.6%; 86). Over time, 106 (36.4%) patients developed valve disease. No significant association was found between aortic, pulmonary, mitral, or tricuspid valve disease and dialysis duration. Secondary hyperparathyroidism was the sole statistically significant factor for mitral valve disease in the regression model (OR 2.59 [95% CI: 1.09-6.18]; p = 0.031). Conclusion: CKD patients on renal replacement therapy exhibit a high frequency of valve disease, particularly mitral and aortic valve disease. However, no link was established between dialysis duration and valve disease occurrence or progression.

Resumo Introdução: Doenças cardiovasculares são uma causa significativa de morte em pacientes com Doença Renal Crônica (DRC). A calcificação valvar é preditor de mortalidade cardiovascular e doença arterial coronariana. Objetivo: Avaliar a frequência, fatores associados e progressão de valvopatias em pacientes com DRC. Métodos: Coorte retrospectiva com 291 pacientes ambulatoriais no Hospital das Clínicas de Pernambuco. Inclusão: ≥18 anos com DRC e valvopatia; exclusão: tratamento conservador ou dados incompletos. Variáveis clínicas e laboratoriais foram comparadas e categorizadas por tempo de terapia dialítica (TTD): <5 anos, 5-10 anos, >10 anos. Foram aplicados os testes Qui-quadrado, exato de Fisher, ANOVA, Kruskal-Wallis. Associação entre valvopatia e TTD foi avaliada por regressão binária. Significância foi definida como p < 0,05. Resultados: A valvopatia mitral foi encontrada em 82,5% (240) dos casos, seguida da aórtica (65,6%; 86). Houve progressão da doença valvar em 106 (36,4%) pacientes. Não houve associação entre valvopatias aórtica, pulmonar, mitral ou tricúspide e TTD. Hiperparatireoidismo secundário foi a única variável explicativa significativa na regressão para valvopatia mitral (OR 2,59 [IC95%: 1,09-6,18]; p = 0,031). Conclusão: Encontramos alta frequência de valvopatias, especialmente mitral e aórtica, aem pacientes com DRC. Não houve associação entre TTD e valvopatia.

Controversy on the CONVINCE study findings: the PRO take / Controvérsia sobre os achados do estudo CONVINCE: a perspectiva PRO

ABSTRACT The CONVINCE study, recently published in the New England Journal of Medicine, reveals a groundbreaking 23% reduction in the relative risk of all-cause mortality among end-stage kidney patients undergoing high convective volume hemodiafiltration. This significant finding challenges the conventional use of high-flux hemodialysis and offers hope for improving outcomes in chronic kidney disease patients. While some controversies surround the study's findings, including concerns about generalizability and the causes of death, it is essential to acknowledge the study's design and its main outcomes. The CONVINCE study, part of the HORIZON 2020 project, enrolled 1360 patients and demonstrated the superiority of hemodiafiltration in reducing all-cause mortality overall, as well as in specific patient subgroups (elderly, short vintage, non-diabetic, and those without cardiac issues). Interestingly, it was shown that hemodiafiltration had a protective effect against infection, including COVID-19. Future research will address sustainability, dose scaling effects, identification of subgroups especially likely to benefit and cost-effectiveness. However, for now, the findings strongly support a broader adoption of hemodiafiltration in renal replacement therapy, marking a significant advancement in the field.

RESUMO O estudo CONVINCE, publicado recentemente no New England Journal of Medicine, revela uma redução inovadora de 23% no risco relativo de mortalidade por todas as causas entre pacientes renais em estágio terminal submetidos à hemodiafiltração de alto volume de convecção. Esse achado significativo desafia o uso convencional da hemodiálise de alto fluxo e oferece esperança de melhoria dos desfechos em pacientes com doença renal crônica. Embora algumas controvérsias cerquem os achados do estudo, incluindo preocupações sobre a generalização e as causas de óbito, é essencial reconhecer o desenho do estudo e seus principais desfechos. O estudo CONVINCE, parte do projeto HORIZON 2020, inscreveu 1.360 pacientes e demonstrou a superioridade da hemodiafiltração na redução da mortalidade por todas as causas em geral, bem como em subgrupos específicos de pacientes (idosos, HD de curta duração, não diabéticos e aqueles sem problemas cardíacos). Curiosamente, demonstrou-se que a hemodiafiltração teve um efeito protetor contra infecções, incluindo a COVID-19. Pesquisas futuras abordarão sustentabilidade, efeitos de escalonamento da dose, identificação de subgrupos especialmente propensos a se beneficiar e a relação custo-benefício. No entanto, por ora, os achados apoiam fortemente uma adoção mais ampla da hemodiafiltração na terapia renal substitutiva, marcando um avanço significativo na área.

High volume online hemodiafiltration: a global perspective and the Brazilian experience / Hemodiafiltração on-line de alto volume: uma perspectiva global e a experiência brasileira

ABSTRACT Online hemodiafiltration (HDF) is a rapidly growing dialysis modality worldwide. In Brazil, the number of patients with private health insurance undergoing HDF has exceeded the number of patients on peritoneal dialysis. The achievement of a high convection volume was associated with better clinical imprand patient - reported outcomes confirming the benefits of HDF. The HDFit trial provided relevant practical information on the implementation of online HDF in dialysis centers in Brazil.

Dying with end stage kidney disease: factors associated with place of death on a palliative care program / Fim de vida na doença renal terminal: fatores associados ao local de óbito num programa de cuidados paliativos

Abstract Introduction: End of life care of patients with end-stage kidney disease (ESKD) may be particularly challenging and requires the intervention of a specialized palliative care team (PCT). Objective: To characterize the population of ESKD patients referred to a PCT and evaluate the determinants of planned dying at home. Methods: We performed a retrospective observational cohort study of all patients with ESKD referred to our PCT between January 2014 and December 2021 (n = 60) and further characterized those with previously known ESKD regarding place of death (n = 53). Results: The majority of the patients were female and the median age was 84 years. Half of the patients were on conservative treatment, 43% were on chronic hemodialysis, and the remainder underwent hemodialysis on a trial basis and were subsequently suspended. Of those with previously known ESKD, 18% died at home and neither gender, age, cognition, performance status, comorbidities, CKD etiology, or treatment modality were associated with place of death. Anuria was significantly associated with dying at the hospital as was shorter time from dialysis suspension and death. Although not reaching statistical significance, we found a tendency towards a longer duration of palliative care follow-up in those dying at home. Conclusion: Dying at home is possible in a palliative domiciliary program regardless of age, gender, etiology of CKD, major comorbidities, and treatment modality. Anuria and shorter survival from RRT withdrawal may be limiting factors for planned dying at home. A longer follow-up by palliative care may favor dying at home.

Resumo Introdução: Os cuidados de fim de vida em doentescom doença renal terminal (DRT) podem ser desafiantes e necessitar do apoio de uma equipa especializada em cuidados paliativos (ECP). Objetivo: Caracterizar a população de doentes com DRT encaminhada à ECP e avaliar os determinantes para um fim de vida planeado no domicílio. Métodos: Realizámos um estudo de coorte observacional retrospectivo dos doentes com DRT encaminhados à ECP entre janeiro/2014 e dezembro/2021 (n = 60) e caracterizámos aqueles com DRT previamente conhecida relativamente ao local de fim de vida (n = 53). Resultados: A maioria dos pacientes eram mulheres comidade mediana de 84 anos. Metade dos doentes encontrava-se em tratamento conservador, 43% em hemodiálise crónica e os restantes suspenderam diálise iniciada agudamente. Daqueles com DRT previamente conhecida, 18% morreram em casa. Não foi objetivada associação entre género, idade, cognição, status funcional, comorbilidades, etiologia da DRC ou modalidade de tratamento da DRT e o local de óbito. A anúria e a menor sobrevida após suspensão de diálise associaram-se a um fim de vida no hospital e verificámos uma tendência para o fim de vida em casa nos doentes com mais tempo de acompanhamento pela ECP. Conclusão: O fim de vida no domicílio é possível num programa domiciliário de cuidados paliativos, independentemente de idade, sexo, etiologia da DRC, principais comorbilidades e modalidade de tratamento. A anúria e o menor tempo de sobrevida após suspensão da TRS podem ser fatores limitantes. Um acompanhamento mais longo em cuidados paliativos pode favorecer o fim de vida no domicílio.

Plant-based diets and their effects on the metabolism and survival of chronic renal patients undergoing conservative treatment

Diet therapy in conservative treatment of chronic kidney disease involves protein restriction, but there is not enough evidence to recommend a particular type of protein, whether animal or plant based. However, studies suggest that plant-based diets help reduce the consumption of total and animal protein, reduce the need for nephroprotective drugs, improve complications and bring advantages in terms of disease progression and patient survival. The article considers up-to-date data on the effects of this diet and observed that when low in protein, primarily vegetable and in some cases supplemented with ketoanalogues, it can result in positive clinical outcomes, such as: delay in the decrease in the glomerular filtration rate, lower concentrations of urea, reduction of serum creatinine and phosphorus concentrations, lower metabolic acidosis, higher insulin sensitivity and lower systemic inflammation. As a whole, this dietary pattern may be able to postpone the start of dialysis with less progression of renal insufficiency. Additional research is needed to better characterize this dietary pattern.

La dietoterapia en el tratamiento conservador de la enfermedad renal crónica implica la restricción de proteínas, pero aún no hay pruebas suficientes para recomendar un tipo concreto de proteínas, ya sean animales o vegetales. Sin embargo, los estudios sugieren que las dietas basadas en plantas ayudan a reducir la ingesta de proteínas totales y animales, disminuyen la necesidad de fármacos nefroprotectores, mejoran las complicaciones y presentan ventajas con respecto a la progresión de la enfermedad y la supervivencia de los pacientes. En este artículo se consideran datos actualizados sobre los efectos de esta dieta y se observa que, cuando es hipoproteica, principalmente vegetal y en algunos casos se complementa con cetoanálogos, puede dar lugar a resultados clínicos positivos, como una disminución retardada de la tasa de filtración glomerular, concentraciones más bajas de urea, concentraciones reducidas de creatinina y fósforo séricos, menor acidosis metabólica, mayor sensibilidad a la insulina y menor inflamación sistémica. En conjunto, este patrón dietético tiene el potencial de retrasar el inicio de la diálisis con una menor progresión de la insuficiencia renal. Es necesario seguir investigando para caracterizar mejor este patrón dietético.

Frequency of skin diseases in renal transplant recipients and patients with chronic kidney disease in a tertiary center: a cross-sectional study

ABSTRACT BACKGROUND: The prevalence of chronic kidney disease (CKD) has increased in the recent decades, along with the number of patients in the terminal stages of this disease, requiring transplantation. Some skin disorders are more frequent in patients with CKD and in renal transplant recipients (RTR). OBJECTIVES: To evaluate the frequency of skin diseases in RTR and patients with CKD receiving conservative treatment. DESIGN AND SETTING: This observational cross-sectional study recruited consecutive patients with CKD and RTR from a nephrology clinic at a teaching hospital in Brazil between 2015 and 2020. METHODS: Quantitative, descriptive, and analytical approaches were used. The sample was selected based on convenience sampling. Data were collected from dermatological visits and participants' medical records. RESULTS: Overall, 308 participants were included: 206 RTR (66.9%, median age: 48 years, interquartile range [IQR] 38.0-56.0, 63.6% men) and 102 patients with CKD (33.1%, median age: 61.0 years, IQR 50.0-71.2, 48% men). The frequency of infectious skin diseases (39.3% vs. 21.6% P = 0.002) were higher in RTR than in patients with CKD. Neoplastic skin lesions were present in nine (4.4%) RTR and in only one (1.0%) patient with CKD. Among the RTR, the ratio of basal cell carcinoma to squamous cell carcinoma was 2:1. CONCLUSIONS: This study revealed that an increased frequency of infectious skin diseases may be expected in patients who have undergone kidney transplantation. Among skin cancers, BCC is more frequently observed in RTR, especially in those using azathioprine.

Enfermedad renal crónica agudizada como causa de mortalidad en paciente con COVID-19

Introducción: La infección por SARS-CoV-2 en pacientes con enfermedad renal crónica se asocia a larga estadía hospitalaria, aparición de complicaciones y mortalidad. Objetivo: Describir el caso clínico de un paciente con enfermedad renal crónica agudizada como causa de mortalidad en presencia de la infección por la COVID-19. Presentación del caso: Paciente masculino de 69 años con antecedentes de enfermedad renal crónica estadio 3a que ingresó a la institución hospitalaria con diagnóstico de COVID-19 y que durante su estadía presentó cifras elevadas de creatinina sérica con el consiguiente desarrollo de injuria renal aguda. Después de cinco sesiones de hemodiálisis mejoró el estado general del paciente y las cifras de creatinina disminuyeron parcialmente. A pesar de la mejoría clínica, el paciente progresó hacia el último estadio de la enfermedad renal crónica. Luego de tres semanas bajo terapia hemodialítica crónica falleció a causa de síndrome coronario agudo con elevación del segmento ST. Conclusiones: El pronóstico de los pacientes con daño renal que desarrollan la COVID-19 es desfavorable. La infección por SARS-CoV-2 favorece la progresión hacia los estadios finales de la enfermedad renal crónica con riesgo incrementado de la mortalidad.

Introduction: SARS-CoV-2 infection in patients with chronic kidney disease is associated with a long hospital stay, the appearance of complications and mortality. Objective: To describe the clinical case of a patient with exacerbated chronic kidney disease as a cause of mortality in the presence of COVID-19 infection. Clinical case: A 69-year-old male patient with a history of stage 3a chronic kidney disease who was admitted to a hospital with a diagnosis of COVID-19 and who during his stay presented elevated serum creatinine levels with the subsequent development of acute kidney injury. After five hemodialysis sessions, the patient's general condition improved and the creatinine levels partially decreased. Despite clinical improvement, the patient progressed to the last stage of chronic kidney disease. After three weeks under chronic hemodialytic therapy, the patient died due to ST-segment elevation acute coronary syndrome. Conclusions: The prognosis of patients with kidney damage who develop COVID-19 is unfavorable. SARS-CoV-2 infection favors progression to the final stages of chronic kidney disease with an increased risk of mortality.

The effect of Vitamin E supplementation on inflammatory biomarkers and oxidative stress in patients with chronic kidney disease on hemodialysis: A systematic review

Hemodialysis, along with chronic kidney disease (CKD), intensifies the inflammatory process and oxidative stress in patients undergoing treatment. In this context, Vitamin E supplementation can mitigate the deleterious effects resulting from these processes. This is a systematic review whose objective was to evaluate the effect of Vitamin E supplementation on inflammatory biomarkers and oxidative stress in patients with CKD on hemodialysis. This review was prepared according to the methodology for systematic reviews and meta-analyses (PRISMA) and the search was performed in Pubmed, Cochrane Library, Scopus and Web of Science databases. The risk of bias of the included studies was assessed with the Cochrane Risk of Bias Tool. Twelve studies developed between 2006 and 2020 were included in this review. Most of them (n= 11) used vitamin E doses ranging from 400 IU to 888 IU and the supplementation time ranged from 2 weeks to 12 months. Of all the 12 articles included, 25% (n= 3) analyzed supplementation on biomarkers of oxidative stress and 25% (n= 3) addressed these parameters simultaneously. A positive effect was observed in 58.4% of the studies (n= 7). Thus, Vitamin E supplementation can be effective in mitigating the inflammatory process and oxidative stress, however, it is worth noting that the effect depends on the dose and time of supplementation.

La hemodiálisis, junto con la enfermedad renal crónica (ERC), intensifica el proceso inflamatorio y el estrés oxidativo en los pacientes en tratamiento. En este contexto, la suplementación con vitamina E puede mitigar los efectos nocivos resultantes de estos procesos. Esta es una revisión sistemática cuyo objetivo fue evaluar el efecto de la suplementación con vitamina E sobre biomarcadores inflamatorios y estrés oxidativo en pacientes con ERC en hemodiálisis. La revisión se elaboró según la metodología para revisiones sistemáticas y metanálisis (PRISMA) y la búsqueda se realizó en las bases de datos Pubmed, Cochrane Library, Scopus y Web of Science. El riesgo de sesgo de los estudios incluidos se evaluó con la Herramienta Cochrane de Riesgo de Sesgo (Cochrane Risk of Bias Tool). En esta revisión se incluyeron doce estudios desarrollados entre 2006 y 2020. La mayoría (n= 11) utilizó dosis de vitamina E que oscilaban entre 400 UI y 888 UI y el tiempo de suplementación osciló entre 2 semanas y 12 meses. De los 12 artículos incluidos, 25% (n= 3) analizaba la suplementación en biomarcadores inflamatorios, 50% (n= 6) en biomarcadores de estrés oxidativo y 25% (n= 3) en estos parámetros simultáneamente. Se observó un efecto positivo en 58,4% de los estudios (n= 7). Por lo tanto, la suplementación con vitamina E puede ser efectiva para mitigar el proceso inflamatorio y el estrés oxidativo, sin embargo, vale la pena señalar que el efecto depende de la dosis y el tiempo de suplementación.

Esta pesquisa de revisão sistemática seguiu os parâmetros propostos pelo PRISMA. A busca dos artigos foi realizada na base de dados PubMed. Foram encontrados 113 artigos, sendo que destes 31 foram selecionados para análise. Analisando a amostra dos estudos verificou-se que 19,3% dos estudos tiveram grupo controle, que o instrumento mais utilizado foi Mini Exame do Estado Mental (41,9%) e que pacientes com idade mais avançada e os pacientes com mais tempo de tratamento hemodialítico tinham piores escores cognitivos. Conclui-se que a HD pode reduzir a função cognitiva de pessoas com IRC.

Xerostomia impacts oral health-related quality of life in individuals with end-stage renal disease / Xerostomia impacta a qualidade de vida relacionada à saúde bucal de indivíduos em estágio final de doença renal crônica

ABSTRACT Objective: This two-centre cross-sectional study aimed to evaluate whether xerostomia occurrence is associated with oral health-related quality of life (OHRQoL) in patients with end-stage renal disease (ESRD) after the adjustment for potential confounders. Methods: Oral examinations were performed by calibrated examiners for untreated dental caries, periodontitis and tooth loss in 180 adults with ESRD. The presence of xerostomia was determined using the global question "How often does your mouth feel dry?". OHRQoL was evaluated by the simplified version of the Oral Health Impact Profile (OHIP14) questionnaire. Multivariate zero-inflated negative binomial regression analysis was used to calculate the incidence rate ratios (IRR) for the nonzero scores and odds ratios (OR) of having no impact in OHIP14 scores according to the presence of exposure. Results: In the adjusted model, xerostomia (IRR = 1.57; 95% CI: 1.12 to 2.20) was associated with poorer OHRQoL. The adjusted domain-specific analysis revealed that xerostomia occurrence significantly impacted the psychological disability and social disability, and the chance of having no impact was lower for the psychological discomfort domain (OR = 0.84; 95% CI: 0.12 to 0.98). Conclusion: Xerostomia exert an impact on OHRQoL in patients with ESRD, mainly in the psychological and social disabilities constructs.

RESUMO Objetivo: Este estudo transversal realizado em dois centros teve como objetivo avaliar se a ocorrência de xerostomia está associada à qualidade de vida relacionada à saúde bucal (QVRSB) em pacientes com doença renal crônica em estágio final (DRCEF) após o ajuste para potenciais fatores de confusão. Métodos: Exames bucais foram realizados por examinadores calibrados para cárie dentária não tratada, periodontite e perda dentária em 180 adultos com DRCEF. A presença de xerostomia foi determinada por meio da pergunta global "Com que frequência você fica com a boca seca?". A QVRSB foi avaliada pela versão simplificada do questionário Oral Health Impact Profile (OHIP-14). A análise multivariada de regressão binomial negativa inflacionada por zero foi usada para calcular as taxas de incidência (IRR) para os escores diferentes de zero e os razões de chance (OR) de não haver impacto nos escores do OHIP-14 de acordo com a presença dA exposição. Resultados: No modelo ajustado, a xerostomia (IRR = 1,57; IC 95%: 1,12 a 2,20) foi associada a pior QVRSB. A análise específica por domínio revelou que a ocorrência de xerostomia impactou significativamente a incapacidade psicológica e a incapacidade social, e a chance de não haver impacto foi menor para o domínio desconforto psicológico (OR = 0,84; IC95%: 0,12 a 0,98). Conclusão: A xerostomia exerce impacto sobre a QVRSB em pacientes com DRCEF, principalmente nos construtos de deficiência psicológica e social.

Enfoque diagnóstico y terapéutico de la anemia causada por la insuficiencia renal crónica

Introducción: La insuficiencia renal crónica es un trastorno en el que las funciones renales disminuyen de forma progresiva e irreversible. Debido a esta disminución, los riñones pierden su capacidad de eliminar los residuos, concentrar la orina y mantener los niveles adecuados de electrolitos en la sangre. Objetivo: Actualizar los conocimientos para el establecimiento del diagnóstico precoz en el tratamiento de la anemia en pacientes con insuficiencia renal crónica Método: Se realizó una búsqueda bibliográfica de artículos científicos e información en las bases de datos de MEDLINE, Scopus, Redalyc y Latindex, a su vez se complementa con literatura médica encontrada en plataformas digitales como Google Académico. De 68 artículos identificados, se seleccionaron 16 publicaciones que cumplían con los criterios de inclusión, exclusión y de la Declaración PRISMA. Resultados: El diagnóstico de la anemia se debe enfocar en el hemograma, reticulocitos, estado del hierro, vitamina B12 y ácido fólico, mientras que la terapia se basa en el uso de hierro, agentes estimuladores de eritropoyesis y en ciertos casos eritropoyetina. Conclusiones: Brindar un tratamiento precoz y óptimo a los pacientes con insuficiencia renal crónica disminuye el riesgo de aparición de anemia normocítica normocrómica de tipo hipoproliferativa.

Introduction: Chronic kidney failure is a disorder in which kidney functions decrease progressively and irreversibly. Due to this decrease, the kidneys lose their ability to eliminate waste, concentrate urine, and maintain adequate levels of electrolytes in the blood. Objective: To update knowledge for the establishment of early diagnosis in the treatment of anemia in patients with chronic renal failure Method: A bibliographic search of scientific articles and information was carried out in the MEDLINE, Scopus, Redalyc and Latindex databases, to In turn, it is complemented with medical literature found on digital platforms such as Google Scholar. Of 68 articles identified, 16 publications were selected that met the inclusion, exclusion and PRISMA Statement criteria. Results: The diagnosis of anemia should focus on the blood count, reticulocytes, iron status, vitamin B12 and folic acid, while therapy is based on the use of iron, erythropoiesis-stimulating agents and in certain cases erythropoietin. Conclusions: Providing early and optimal treatment to patients with chronic renal failure reduces the risk of developing hypoproliferative normocytic normochromic anemia.

Quality of life and functional capacity in depressive patients on hemodialysis: a systematic review and meta-analysis

Depression is a common disorder in patients with chronic kidney disease (CKD), and some data support its relationship with functional capacity and quality of life. However, to date, this has not been evaluated systematically or through meta-analysis. We sought to investigate the relationship of quality of life and functional capacity with depressive disorder in patients with CKD on hemodialysis. This systematic review considered studies published up to 2021 and included cross-sectional and cohort studies. PubMed, Embase, SPORTDiscus, Web of Science, and Cochrane (CENTRAL) databases were used to search for studies. The New Castle-Ottawa Quality Assessment scale was used to measure the quality of the studies. A total of 4,626 studies were found and, after applying the selection criteria, 16 studies (2,175 patients) remained for qualitative analysis and 10 for meta-analysis (1,484 patients). The physical component summary (MD=-6.563; 95%CI: −9.702 to −3.424) and mental component summary (MD=-18.760; 95%CI: −28.641 to −8.879) were lower in depressive patients, as in all Short Form Health Survey 36 (SF-36) domains. Only one study provided data regarding functional capacity, but it was not evaluated by the defined outcome measure. Twelve studies were classified as "moderate quality" (5 to 6 stars) and four were classified as "low-quality" (0 to 4 stars). This meta-analysis with CKD patients on hemodialysis showed a negative relationship between depression and quality of life, with worsening in all physical and mental domains of the SF-36 in depressed patients.

The burden of coronary heart disease in simultaneous pancreas-kidney transplantation: coronary angiography as a diagnostic method for all? - a retrospective study / O peso da doença arterial coronariana no transplante de pâncreas-rim simultâneo: angiografia coronária como método diagnóstico para todos? - um estudo retrospectivo

Abstract Introduction: Type 1 diabetes mellitus is associated with an increased risk of coronary artery disease, which is frequently asymptomatic. This risk increases significantly in those with nephropathy. In selected patients, simultaneous pancreas-kidney transplantation is the renal and pancreatic replacement therapy of choice, as it increases longevity and stabilizes diabetic complications. Despite essential, universal screening protocols are still controversial for coronary artery disease in this population. Methods: We retrospectively analysed 99 simultaneous pancreas-kidney recipients from our centre from 2011 to 2018 and selected 77 patients who underwent coronary angiography during the pre-transplant evaluation. Our aim was to identify potential risk factors associated with significant lesions on coronary angiography. Results: Almost half of our cohort of 77 candidates submitted to coronary angiography had coronary artery disease. Of these, nearly 30% underwent revascularization, although only one of them reported symptoms of myocardial ischemia. In a univariate analysis, the presence of smoking habits was the only risk factor for coronary artery disease. We also found that 20 or more years of type 1 diabetes mellitus was significantly associated with the presence of coronaropathy. Discussion: Selection of diabetic candidates with acceptable cardiac risk before simultaneous pancreas-kidney transplantation is imperative. Given the impact of a correct diagnosis and a low procedural risk, we defend the routine use of coronary angiography as the initial screening method for coronary artery disease in this population. Particularly care must be taken in evaluating asymptomatic patients with long-term type 1 diabetes mellitus and smokers.

Resumo Introdução: O diabetes mellitus tipo 1 está associado ao risco aumentado de doença arterial coronariana, que é frequentemente assintomática. Este risco aumenta significativamente em pessoas com nefropatia. Em pacientes selecionados, o transplante de pâncreas- rim simultâneo é a terapia substitutiva, renal e pancreática, de escolha, pois aumenta a longevidade e estabiliza complicações diabéticas. Apesar de essenciais, protocolos de triagem universais ainda são controversos para doença arterial coronariana nesta população. Métodos: Analisamos retrospectivamente 99 receptores de pâncreas-rim simultâneo de nosso centro, de 2011 a 2018, e selecionamos 77 pacientes que realizaram angiografia coronária durante avaliação pré-transplante. Nosso objetivo foi identificar fatores de risco potenciais associados a lesões significativas na angiografia coronária. Resultados: Quase metade de nossa coorte de 77 candidatos submetidos à angiografia coronária apresentou doença arterial coronariana. Destes, quase 30% foram submetidos à revascularização, embora apenas um tenha relatado sintomas de isquemia miocárdica. Em uma análise univariada, a presença do hábito de fumar foi o único fator de risco para doença arterial coronariana. Também descobrimos que 20 ou mais anos de diabetes mellitus tipo 1 estavam significativamente associados à presença de coronariopatia. Discussão: A seleção de candidatos diabéticos com risco cardíaco aceitável antes do transplante de pâncreas-rim simultâneo é imperativa. Dado o impacto de um diagnóstico correto e baixo risco de procedimento, defendemos o uso rotineiro da angiografia coronária como método de triagem inicial para doença arterial coronariana nesta população. Deve-se ter um cuidado especial na avaliação de pacientes assintomáticos com diabetes mellitus tipo 1 de longa duração e fumantes.

Impact of telemedicine on metabolic control and hospitalization of peritoneal dialysis patients during the COVID-19 pandemic: a national multicentric cohort study / Impacto da telemedicina no controle metabólico e hospitalização de pacientes em diálise peritoneal durante a pandemia de COVID-19: um estudo de coorte multicêntrico nacional

Abstract Introduction: The coronavirus-19 pandemic threatens the lives of all people, but results in higher mortality rates for patients with end-stage kidney disease (ESKD) including those on peritoneal dialysis (PD). Telemedicine was the main alternative to reduce exposure to the virus, but it was introduced in the Brazil without proper training. Objective: To investigate the impact of telemedicine on metabolic control, peritonitis rates, and hospitalization in PD patients during the pandemic. Methods: This was a retrospective multicenter cohort study. We included all adult patients on chronic PD from 9 clinics selected by convenience during the pandemic. The outcomes of interest were measured and compared between before and after switching to telemedicine using repeated measure analysis and multilevel Poisson regression. Results: The study included 747 patients with a mean age of 59.7±16.6 years, of whom 53.7% were male and 40.8% had diabetes. Biochemical parameters including hemoglobin, potassium, phosphate, calcium, and urea serum levels did not change significantly after transition to telemedicine. There was no association between telemedicine and peritonitis rates. In contrast, hospitalization rates increased significantly in the telemedicine period. The incidence rate ratio (IRR) for hospitalization in the telemedicine period was 1.54 (95%CI 1.10-2.17; p 0.012) and 1.57 (95%CI 1.12-2.21; p 0.009) in the mixed-effects Poisson regression before and after adjustment for the presence of confounders. Admissions for hypervolemia and infections not related to PD doubled after transition to telemedicine. Conclusion: The implementation of telemedicine without proper training may lead to an increase in adverse events in PD patients.

Resumo Introdução: A pandemia do coronavírus-19 ameaça a vida de todas as pessoas, mas resulta em uma alta taxa de mortalidade em pacientes com doença renal em estágio terminal (DRET), incluindo aqueles em diálise peritoneal (DP). A telemedicina foi a principal alternativa para reduzir a exposição ao vírus, mas foi introduzida no Brasil sem treinamento adequado. Objetivo: Investigar o impacto da telemedicina no controle metabólico, taxas de peritonite e hospitalização em pacientes em DP na pandemia. Métodos: Estudo de coorte multicêntrico retrospectivo. Incluímos todos os pacientes adultos em DP crônica de 9 clínicas selecionadas por conveniência durante a pandemia. Desfechos de interesse foram medidos e comparados entre antes e depois da mudança para telemedicina usando análise de medidas repetidas e regressão multinível de Poisson. Resultados: Incluiu-se 747 pacientes com idade média de 59,7±16,6 anos, sendo 53,7% homens e 40,8% diabéticos. Parâmetros bioquímicos, incluindo níveis séricos de hemoglobina, potássio, fosfato, cálcio e ureia não mudaram significativamente após transição para telemedicina. Não houve associação entre telemedicina e taxas de peritonite. Em contraste, taxas de hospitalização aumentaram significativamente no período de telemedicina. A razão de taxas de incidência (RTI) para internação no período de telemedicina foi 1,54 (IC95% 1,10-2,17; p 0,012) e 1,57 (IC95% 1,12-2,21; p 0,009) na regressão multinível de Poisson antes e após ajuste para presença de fatores de confusão. As internações por hipervolemia e infecções não relacionadas à DP dobraram após transição para telemedicina. Conclusão: A implementação da telemedicina sem treinamento adequado pode levar ao aumento de eventos adversos em pacientes em DP.

Actualización en lesión renal aguda inducida por contraste en pediatría

Contexto: la lesión renal aguda inducida por contraste se ha convertido en un tema de gran interés en la comunidad médica a nivel mundial, siendo la tercera causa de lesión renal aguda adquirida en el hospital. Objetivo: el presente artículo presenta una revisión de la literatura con el fin de actualizar los conceptos de esta patología en el personal de la salud que está en contacto con la población pediátrica y que es sometida a procedimientos con medios de contraste. Metodología: en esta revisión narrativa de la literatura, presentamos la definición, los factores de riesgo, el enfoque clínico y las medidas preventivas de la nefropatía inducida por contraste en pediatría. Resultados: se define que hay un deterioro en la función renal aguda después de la administración del medio de contraste en donde se excluyen otras posibles etiologías y se establece una verdadera relación causal con la sustancia. Los factores de riesgo son múltiples, sin embargo, factores estrictamente relacionados en los niños no han sido establecidos en su totalidad. El abordaje de los pacientes que van a ser sometidos a estudios con medios de contraste inicia desde una historia clínica, un examen físico y unas medidas de laboratorio que permiten evaluar el estado basal de cada paciente para instaurar medidas preventivas. Por su parte, las estrategias de prevención de esta condición son múltiples, sin embargo, no existen guías basadas en la evidencia acerca de esta condición en el paciente pediátrico. Conclusiones: el artículo presenta una revisión de la literatura sobre lesión renal aguda para actualizar los conceptos de esta patología en el personal de la salud que está en contacto con la población pediátrica que se somete a procedimientos con medios de contraste.

Context: Contrast-induced acute kidney injury has become a topic of great interest in the medical community worldwide, being the third cause of hospital-acquired acute kidney injury. Purpose: This article presents a review of the literature in order to update the concepts of this pathology in health personnel who are in contact with the pediatric population that undergoes procedures with contrast media. Methodology: In this narrative review of the literature, we present the definition, risk factors, clinical approach, and preventive measures of contrast-induced nephropathy in pediatrics. Results: It is defined as a deterioration in acute renal function after the administration of the contrast medium where other possible etiologies are excluded and a true causal relationship with the substance is established. The risk factors are multiple; nevertheless; Strictly related factors in children have not been fully established. The approach to patients who are going to undergo studies with contrast media begins with a clinical history, physical examination, and laboratory measurements that allow the baseline status of each patient to be evaluated in order to establish preventive measures. The prevention strategies of this condition are multiple; however, there are no evidence-based guidelines on this condition in pediatric patients. Conclusions: This article presents a review of the literature in order to update the concepts of acute kidney injury in health personnel who are in contact with the pediatric population that undergoes procedures with contrast media.

Un entudio controlado aleatorizado / Efeito da técnica de relaxamento de Benson na sobrecarga do cuidador em pacientes em hemodiálise. Um estudo controlado randomizado

Methods. This is a randomized controlled trial study on 52 caregivers of hemodialysis patients referred an universitary hospital at Jahrom. The caregivers were randomly divided into intervention and control groups. In the intervention group, Benson's relaxation was performed twice a day for 15 minutes each time, and continued for one month. Data collection tools included demographic information questionnaire and standard Zarit Burden Interview questionnaire which was completed by all participants before the intervention and one month after it. Results. After the intervention, the mean caregiver burden of hemodialysis patients in the intervention group decreased significantly compared to the control group (p<0.001). The results of paired t-test showed that in the intervention group, the mean scores of caregiver burden after the intervention (14.46± 10.91) was significantly lower than before the intervention (38.33±16.94) (p=0.001). Conclusion. Benson's relaxation method can reduce caregiver burden in caregivers of hemodialysis patients.

Estudio de intervención realizado con la participación de 52 cuidadores de pacientes en hemodiálisis remitidos a un hospital universitario de Jahrom (Iran). Los cuidadores fueron divididos aleatoriamente en los grupos de intervención y de control. En el grupo de intervención, se realizó la técnica de relajación de Benson dos veces al día durante 15 minutos cada vez, y se continuó durante un mes. Las herramientas de recogida de datos incluían un cuestionario de información demográfica y la entrevista de percepción de carga del cuidador "Zarit Burden Interview" que fue completado por todas participantes antes de la intervención y un mes después de terminada la misma. Resultados. Después de la intervención, la carga media de los cuidadores de pacientes en hemodiálisis en el grupo de intervención disminuyó significativamente en comparación con el grupo de control (p<0.001). Los resultados de la prueba t pareada mostraron que en el grupo de intervención, las puntuaciones medias de la carga del cuidador después de la intervención (14.46±10.91) fueron significativamente menores que antes de la intervención (38.33±16.94) (p=0.001). Conclusión. El método de relajación de Benson puede reducir la carga de los cuidadores de pacientes en hemodiálisis.

Objetivo. Investigar o efeito do relaxamento de Benson na sobrecarga do cuidador em cuidadores de pacientes em hemodiálise na cidade de Jahrom. Métodos. Este é um estudo controlado randomizado envolvendo 52 cuidadores de pacientes em hemodiálise encaminhados a um hospital afiliado à Jahrom University of Medical Sciences. Os cuidadores foram divididos aleatoriamente em grupos intervenção (n=24) e controle (n=24). No grupo intervenção, os cuidadores realizaram o relaxamento de Benson duas vezes ao dia por 15 minutos cada, e foi continuado por um mês. A coleta de informações incluiu um questionário de informações demográficas e o questionário padrão Zarit que foi preenchido por todos os participantes antes da intervenção e um mês após o seu preenchimento. Resultado S. A maioria dos cuidadores nos grupos intervenção (79.2%) e controle (64.3%) eram mulheres. Após a intervenção, a sobrecarga média dos cuidadores de pacientes em hemodiálise no grupo intervenção diminuiu significativamente em relação ao grupo controle (p<0.001). Os resultados do teste t pareado mostraram que, apenas no grupo intervenção, os escores médios de sobrecarga do cuidador após a intervenção (14.46 ±10.1) foram significativamente menores do que antes da intervenção (38.33) ±16.94) com p <0.001. Conclusão. O método de relaxamento de Benson demonstrou ser eficaz na redução da sobrecarga dos cuidadores de pacientes em hemodiálise.
