Brazilian Dialysis Survey 2022 / Censo Brasileiro de Diálise 2022

Abstract Introduction: The Brazilian Dialysis Survey (BDS) is an annual national survey about patients on chronic dialysis that contributes to health policies. Objective: To report the 2022 epidemiological data from the BDS of the Brazilian Society of Nephrology (BSN). Methods: A survey was carried out in Brazilian chronic dialysis centers using an online questionnaire that included clinical and epidemiological aspects of patients on chronic dialysis, dialysis therapy data, and dialysis center characteristics. Results: Overall, 28% (n = 243) of the centers answered the questionnaire. In July 2022, the estimated total number of patients on dialysis was 153,831. The estimated prevalence and incidence rates of patients per million population (pmp) were 758 and 214, respectively. Of the prevalent patients, 95.3% were on hemodialysis (HD, 4.6% of these on hemodiafiltration) and 4.7% on peritoneal dialysis (PD). Only 1.3% of patients were not vaccinated against COVID-19. The prevalence of anemia (Hb < 10g/dL) was 27% and hyperphosphatemia (P > 5.5mg/dL) reached 30%. The estimated overall crude annual mortality rate was 17.1%. Conclusions: The absolute number and prevalence rate of patients on chronic dialysis continue to increase. A growing number of patients were receiving hemodiafiltration. The mortality rate decreased, probably due to the end of COVID-19 pandemic. The conclusions were drawn in the context of relatively low voluntary participation, which imposed methodological limitations on our estimates.

Resumo Introdução: O Censo Brasileiro de Diálise (CBD) é uma pesquisa nacional anual sobre pacientes em diálise crônica que contribui para as políticas de saúde. Objetivo: Informar os dados epidemiológicos de 2022 do CBD da Sociedade Brasileira de Nefrologia (SBN). Métodos: Foi realizada uma pesquisa em centros brasileiros de diálise por meio de um questionário online que incluiu aspectos clínicos e epidemiológicos de pacientes em diálise crônica, dados da terapia dialítica e características do centro de diálise. Resultados: No total, 28% (n = 243) dos centros de diálise ativos cadastrados na SBN responderam ao questionário. Em julho de 2022, o número total estimado de pacientes em diálise era de 153.831. As taxas estimadas de prevalência e incidência de pacientes por milhão (ppm) de habitantes foram 758 e 214, respectivamente. Dos pacientes prevalentes, 95,3% estavam em hemodiálise (HD; 4,6% desses em hemodiafiltração) e 4,7% em diálise peritoneal (DP). Apenas 1,3% dos pacientes não foram vacinados contra a COVID-19. A prevalência de anemia (Hb < 10g/dL) foi de 27% e de hiperfosfatemia (P > 5,5mg/dL) alcançou 30%. A taxa bruta total anual de mortalidade estimada foi de 17,1%. Conclusões: O número absoluto e a taxa de prevalência de pacientes em diálise crônica continuam a aumentar. Um número crescente de pacientes estava em hemodiafiltração. A taxa de mortalidade diminuiu, provavelmente devido ao fim da pandemia da COVID-19. As conclusões foram de um contexto de participação voluntária relativamente baixa, o que impõe limitações metodológicas às nossas estimativas.

Sex-specific differences in a large cohort of Brazilian incident dialysis patients over 12 years: A retrospective study.

OBJECTIVE: Sex-specific differences in the epidemiology of chronic kidney disease, such as higher prevalence of women on pre-dialysis and men on chronic dialysis treatment, have been reported worldwide. In this regard, data from non-high-income countries are scarce. We aimed to compare the demographic, clinical, and dialysis characteristics of incident dialysis patients, both men and women, in a large cohort of Brazilian patients over a 12-year period. METHODS: This was a multicentric retrospective cohort study coordinated by the Brazilian Society of Nephrology. The study included all adult incident dialysis patients in the Brazilian Dialysis Registry from January 2011 to December 2022. The variables studied encompassed age, skin color, education, CKD etiology, predialysis nephrologist care, dialysis characteristics, and geographic region. Additionally, the sample was analyzed for each of the three 4-year periods over the 12 years of data collection. RESULTS: A total of 24,632 incident dialysis patients were included. Men were 59.1% of the dialysis population, remaining stable over the three 4-year periods. Besides other differences, women started dialysis younger (58.5 ± 16.2 years vs 59.5 ± 14.4 years; p < 0.001), had a lower educational level (less than 8 years at school: 54% vs 44%; p < 0.001), received more predialysis nephrologist care (46.2% vs 44.2%; p = 0.04), and had a higher prevalence of peritoneal dialysis (4.4% vs 3.5%; p = 0.03). CONCLUSION: We consistently observed a higher prevalence of men on dialysis and differences in demographic, clinical, and dialysis characteristics. The underlying reasons for these sex differences still necessitate further clarification.

Hemodialysis in Brazil: differences across geographic regions regarding demographics, laboratory parameters and drug prescription / Hemodiálise no Brasil: diferenças entre regiões geográficas quanto a dados demográficos, parâmetros laboratoriais e prescrição de medicamentos

ABSTRACT Introduction: Brazil has a vast territory divided into five geographic regions with important differences in sociodemographic indices. We aimed to present and compare socio-demographic characteristics, biochemical results, and drug prescription of patients on chronic hemodialysis (HD) treatment in the five geographic regions. Methods: We evaluated data from the Brazilian Dialysis Registry of all adult patients undergoing chronic HD in 2021. Variables included sociodemographic characteristics, serum levels of phosphate, calcium, and albumin, hemoglobin, urea reduction rate, and prescription of phosphate binders, erythropoietin, and intravenous iron. Data from the North and Northeast regions were combined into one group. Results: A total of 13,792 patients (57.9 ± 16.0 years old, 58.5% male, median HD vintage of 31 (11-66) months) from 73 dialysis centers were analyzed. Regional distribution was 59.5% in the Southeast; 21.7% in the South; 5.9% in the Midwest; and 12.9% in the North/Northeast. Sociodemographic features, biochemical results, and medication prescriptions differed across regions. The prevalence of elderly patients was lower in the Midwest and North/Northeast. The South region had the highest prevalence of hyperphosphatemia (41.2%) and urea reduction rate <65% (24.8%), while anemia and hypoalbuminemia were more prevalent in the Southeast, 32.7% and 11.6%, respectively. Conclusion: We found differences in socio-demographics, clinical features, and drug prescriptions across Brazilian geographic regions. Some findings reflect the socio-demographic diversity of the country, while others deserve further elucidation.

Predictors of arteriovenous fistula maturation in hemodialysis patients: a prospective cohort from an ambulatory surgical center in Joinville, Brazil / Preditores da maturação de fístula arteriovenosa de pacientes em hemodiálise: coorte prospectiva de um centro cirúrgico ambulatorial, Joinville, Brasil

ABSTRACT Introduction: The high rate of arteriovenous fistula maturation failure is a concern in a scenario of growing numbers of patients on hemodialysis. Non-vascular factors tied to maturation success have not been fully discussed. Methods: This prospective observational cohort study included patients with CKD on dialysis or pre-dialysis prescribed arteriovenous fistula creation for the first time in an ambulatory surgical center in Joinville, Brazil, from January 2021 to July 2021. Anthropometric aspects, sociodemographic characteristics, comorbidities, and vascular parameters observed in Doppler ultrasound were analyzed. Variables associated with maturation were analyzed in multivariate models by logistic regression. Results: Eighty-eight of 145 participants (60.1%) were males. Included patients had a median age of 59 years. Successful arteriovenous fistula maturation occurred in 113 (77.9%) patients. Factors such as increased BMI, hematocrit, arm circumference, and skinfold thickness were associated with lower chances of arteriovenous fistula maturation in univariate analysis. On the other hand, larger vein and artery diameter and fistulas in the more proximal portion of the arm were associated with higher maturation success. In multivariate analysis, smoking and larger skinfold and arm circumference were associated with lower chances of successful maturation. Increased systolic blood pressure and vein diameter were associated with greater chance of success. Conclusion: In addition to the vascular parameters assessed in Doppler ultrasonography, factors related to obesity and/or nutritional aspects may influence arteriovenous fistula maturation.

Resumo Introdução: A alta taxa de falha na maturação da fístula arteriovenosa é motivo de preocupação para o crescente número de pacientes em hemodiálise. Os fatores não vasculares não foram totalmente estudados em relação ao sucesso da maturação. Métodos: Estudo de coorte prospectivo, observacional de pacientes com DRC diálise ou pré-diálise encaminhados para a primeira criação de fístula arteriovenosa em um centro cirúrgico ambulatorial de Joinville, Brasil, de janeiro de 2021 a julho de 2021. Aspectos antropométricos, características sociodemográficas, comorbidades, além de fatores vasculares verificados pelo ultrassom Doppler. As variáveis associadas à maturação foram analisadas em modelos multivariados por regressão logística. Resultados: Dos 145 pacientes participantes, 88 (60,1%) eram homens, com idade mediana de 59 anos. Houve sucesso na maturação da fístula arteriovenosa em 113 (77,9%) pacientes. Fatores como aumento do IMC, hematócrito, circunferência do braço e valor das dobras cutâneas foram associados a menor chance de maturação da fístula arteriovenosa na análise univariada. Por outro lado, o maior diâmetro da veia e da artéria e fístulas na porção mais proximal do membro superior foram associados a maior sucesso de maturação. Na análise multivariada, tabagismo, maior dobra cutânea e circunferência do braço foram associados a menor chance de sucesso da maturação. O aumento da pressão arterial sistólica e o do diâmetro da veia foram associados a maior chance de sucesso. Conclusão: Além dos aspectos vasculares avaliados pela ultrassonografia Doppler, fatores relacionados à obesidade e/ou a aspectos nutricionais podem influenciar a maturação da fístula arteriovenosa.

Brazilian Dialysis Survey 2021 / Censo Brasileiro de Diálise 2021

ABSTRACT Introduction: The Brazilian Dialysis Survey (BDS) is an important source of national data about people on chronic dialysis that contributes to the formulation of health policies regarding kidney failure. Objective: To report the 2021 epidemiological data from the BDS of the Brazilian Society of Nephrology (BSN). Methods: A survey was carried out in Brazilian chronic dialysis centers using an online questionnaire covering clinical and epidemiological aspects of patients in chronic dialysis, data on dialysis therapy, characteristics of dialysis centers, and the impact of the COVID-19 pandemic of 2021. Results: Thirty percent (n = 252) of the centers answered the questionnaire. In July 2021, the estimated total number of patients on dialysis was 148,363. The estimated prevalence and incidence rates of patients per million population (pmp) were 696 and 224, respectively. Of the prevalent patients, 94.2% were on hemodialysis (HD) (1.8% of these on hemodiafiltration), and 5.8% on peritoneal dialysis (PD); 21% were on the transplant waiting list. The incidence rate of confirmed COVID-19 between January and July 2021 was 1,236/10,000 dialysis patients, and the case-fatality rate reached 25.5%. Up to July 2021, 88.6% of patients had received at least one dose of the anti-SARS-CoV-2 vaccine. The estimated overall and COVID-19 crude annual mortality rates were 22.3% and 5.3%, respectively. Conclusion: The absolute number and the prevalence rate of patients on chronic dialysis continue to increase. Most dialysis patients were vaccinated against COVID-19 during the year. The COVID-19 pandemic was associated to the overall mortality rate.

High prevalence of hyperkalemia in Brazilian chronic dialysis patients and differences across geographic regions / Prevalência elevada de hipercalemia em pacientes brasileiros em diálise crônica e diferenças entre as regiões geográficas

Abstract Introduction: Hyperkalemia is a common multifactorial condition of people on chronic dialysis and is associated with mortality. We aimed to inform and discuss the prevalence of hyperkalemia in a large population of chronic dialysis patients in Brazil and its geographic regions. Methods: Prevalence of hyperkalemia (serum potassium ≥6.0 mEq/L) was assessed in the Brazilian Dialysis Survey (BDS) in July 2019, an online survey of voluntary participation in which all dialysis centers registered at the Brazilian Society of Nephrology were invited. Results: Approximately one-third (n=263 of 805) of the Brazilian dialysis clinics participated. The prevalence of hyperkalemia in the whole population was 16.1% (n=7,457 of 46,193; 95%CI=15.8-16.5%,), and varied from 12.1% in the North to 18.7% in the Northeast. Conclusion: We found a high prevalence of hyperkalemia in a large Brazilian chronic dialysis population. A nationwide investigation of risk factors, treatment options, and whether this high prevalence contributes to dialysis mortality is warranted.

Resumo Introdução: A hipercalemia é uma condição multifatorial comum em pessoas em diálise crônica e está associada à mortalidade. Nosso objetivo foi informar e discutir a prevalência de hipercalemia em uma grande população de pacientes em diálise crônica no Brasil e diferenças entre as regiões geográficas. Métodos: A prevalência de hipercalemia (potássio sérico ≥6,0 mEq/L) foi avaliada por meio do Censo Brasileiro de Diálise (CBD) em Julho de 2019, uma pesquisa online de participação voluntária na qual foram convidados todos os centros de diálise registrados na Sociedade Brasileira de Nefrologia. Resultados: Aproximadamente um terço (n=263 de 805) das clínicas de diálise brasileiras participaram. A prevalência de hipercalemia na população total foi de 16,1% (n=7.457 de 46.193; IC95%=15,8-16,5%), e variou de 12,1% no Norte a 18,7% no Nordeste. Conclusão: Encontramos uma elevada prevalência de hipercalemia em umagrande população brasileira em diálise crônica. É necessária uma investigação nacional dos fatores de risco, opções de tratamento e se esta alta prevalência contribui para a mortalidade desta população.

Prevalence and factors associated with Frailty Syndrome in elderly people in Joinville / Prevalencia y factores asociados al Síndrome de Fragilidad en adultos mayores de Joinville / Prevalência e fatores associados à Síndrome da Fragilidade em idosos de Joinville

INTRODUCTION: With the aging of the Brazilian population, to scale and evaluate the profile of the vulnerable population for having the Frailty Syndrome in Elderly (FSE) and understanding its associated factors is of great importance. OBJECTIVE: To analyze the profile of elders corresponding to the information referred in the frailty indicators on the Edmonton Frail Scale on a geriatric specialized facility. METHODOLOGY: The present study is a cross-sectional, analytical study, with the elders from a geriatrics specialized facility in Joinville, Brazil. It was analyzed the social-economic profiles (gender, ethnicity, income and schooling) and the evaluation for the FSE, as well as comorbidities present. The project has been approved by the Ethics in Research Committee of UNIVILLE under the protocol number 40940020.6.0000.5366. RESULTS: the results were obtained from the 141 elderly interviewed, with 74 years old as the average age. Majority (60%) female, white (90,2%), of low scholar education (56%) and married or in a stable relationship (53,2%). The prevalence of some sort of fragility was of 17,7% (IC95%). DISCUSSION: Although the discussion over the criteria to establish FSE, the present study was based on the Edmonton Frail Scale. The local sample analyzed demonstrated how the discussion over schooling, smoking, income and the high rates of comorbidities predisposes to FSE and, in that way, also in a higher prevalence of elderly falls. This aligns with previous literature studies which showcase higher prevalence of falls in patients with these epidemiological characteristics. CONCLUSION: Despite some limitations of this present study, such as it being done in a well respected specialized geriatric facility, it does demonstrate the local profile of the elderly stricken with FSE.

INTRODUCCIÓN: Con el envejecimiento de la población brasileña, escalar y evaluar el perfil de la población vulnerable por tener el Síndrome de Fragilidad del Anciano (FSE) y comprender sus factores asociados es de gran importancia. OBJETIVO: Analizar el perfil de los ancianos correspondientes a las informaciones referidas en los indicadores de fragilidad de la Escala de Fragilidad de Edmonton en un establecimiento especializado en geriatría. METODOLOGÍA: El presente estudio es un estudio transversal, analítico, con ancianos de una unidad especializada en geriatría de Joinville, Brasil. Se analizaron los perfiles socioeconómicos (género, etnia, renta y escolaridad) y la evaluación para el FSE, así como las comorbilidades presentes. El proyecto ha sido aprobado por el Comité de Ética en Investigación de UNIVILLE bajo el protocolo número 40940020.6.0000.5366. RESULTADOS: los resultados fueron obtenidos de los 141 ancianos entrevistados, con 74 años como promedio de edad. Mayoritariamente (60%) mujeres, blancas (90,2%), de baja escolaridad (56%) y casadas o en pareja estable (53,2%). La prevalencia de algún tipo de fragilidad fue del 17,7% (IC95%). DISCUSIÓN: A pesar de la discusión sobre los criterios para establecer FSE, el presente estudio se basó en la Escala de Frágil de Edmonton. La muestra local analizada demostró cómo la discusión sobre la escolaridad, el tabaquismo, la renta y los altos índices de comorbilidades predisponen a la EEF y, de ese modo, también a una mayor prevalencia de caídas en ancianos. Esto se alinea con estudios previos de la literatura que muestran una mayor prevalencia de caídas en pacientes con estas características epidemiológicas. CONCLUSIÓN: A pesar de algunas limitaciones de este presente estudio, como que se realizó en un centro geriátrico especializado muy respetado, demuestra el perfil local de los ancianos afectados por FSE.

INTRODUÇÃO: Com o envelhecimento da população Brasileira, dimensionar e avaliar o perfil da população vulnerável a ter a Síndrome da Fragilidade no Idoso (SFI) e entender seus fatores associados é de grande importância. OBJETIVO: Analisar o perfil de idosos que correspondem às informações referentes aos indicadores de fragilidade do questionário de fragilidade de Edmonton, em uma clínica especializada em geriatria. MÉTODO: O presente estudo é do tipo transversal, analítico, com idosos da Unidade especializada de atenção geriátrica em Joinville, Brasil. Foram analisados perfil social econômico (escolaridade, renda, raça, sexo) e a avaliação para a SFI e as comorbidades no idoso. O projeto foi aprovado pelo Comitê de Ética em Pesquisa da UNIVILLE sob parecer de n° 40940020.6.0000.5366. RESULTADO: Os resultados do estudo foram a partir dos 141 idosos entrevistados, com uma média de 74 anos de idade. A maioria (60%) do sexo feminino, de cor branca (90,1%), de baixa escolaridade (56%) e casados ou em união estável (53,2%). A prevalência de algum nível de fragilidade foi de 17,7% (IC95%). DISCUSSÃO: Apesar da discussão sobre os critérios para definição da SFI, o presente estudo baseou-se no questionário de fragilidade de Edmonton - Edmonton Frail Scale. A amostra local da população representa como discussão sobre a escolaridade, tabagismo, renda e o grande número de comorbidades predispõe a SFI e, dessa forma, também uma prevalência maior de queda do idoso. Isso converge com estudos prévios na literatura que ilustram maior prevalência de queda em pacientes com esse perfil epidemiológico. Conclusão: Apesar de algumas limitações do estudo como de ter sido realizado em um serviço de referência em geriatria, o estudo molda o perfil local da população idosa acometida pela SFI.

Prevalence and Determinants of Predialysis Dietitian Follow-Up: Results From the Brazilian Dialysis Registry.

OBJECTIVE: We aimed to evaluate the prevalence and sociodemographic determinants of predialysis dietitian follow-up in a large cohort of Brazilian dialysis patients. METHODS: We retrospectively evaluated data from all incident adult dialysis patients included in the Brazilian Dialysis Registry from January 2011 to September 2021. Predialysis dietitian follow-up was classified as present when a period more than 6 months of dietitian care was reported. Gender, age, skin color, education, body mass index, chronic kidney disease etiology, first chronic dialysis program, healthcare provider, and geographic regions were tested in logistic regression models. RESULTS: Ten thousand three hundred and eighty two patients met the inclusion criteria and 1,254 (12.1%) reported predialysis dietitian follow-up, most of them referred by a nephrologist (94.2%). The independent determinants of dietitian follow-up were older age, white skin color, higher education level, not having diabetes, living in North/Northeast and South (compared to Southeast), and having a nonpublic healthcare provider. When considered only patients under a predialysis care of a nephrologist, higher education, hemodialysis as the first dialysis modality, and living in the North/Northeast and South regions (compared with Southeast) were associated with dietitian follow-up. CONCLUSION: Predialysis dietitian follow-up for more than 6 months in a country where the public health system is the main dialysis provider is still very low. The nephrologist is pivotal for referral to dietitians but socioeconomic factors also seem to play a role in this regard.

Brazilian Dialysis Survey 2021.

INTRODUCTION: The Brazilian Dialysis Survey (BDS) is an important source of national data about people on chronic dialysis that contributes to the formulation of health policies regarding kidney failure. OBJECTIVE: To report the 2021 epidemiological data from the BDS of the Brazilian Society of Nephrology (BSN). METHODS: A survey was carried out in Brazilian chronic dialysis centers using an online questionnaire covering clinical and epidemiological aspects of patients in chronic dialysis, data on dialysis therapy, characteristics of dialysis centers, and the impact of the COVID-19 pandemic of 2021. RESULTS: Thirty percent (n = 252) of the centers answered the questionnaire. In July 2021, the estimated total number of patients on dialysis was 148,363. The estimated prevalence and incidence rates of patients per million population (pmp) were 696 and 224, respectively. Of the prevalent patients, 94.2% were on hemodialysis (HD) (1.8% of these on hemodiafiltration), and 5.8% on peritoneal dialysis (PD); 21% were on the transplant waiting list. The incidence rate of confirmed COVID-19 between January and July 2021 was 1,236/10,000 dialysis patients, and the case-fatality rate reached 25.5%. Up to July 2021, 88.6% of patients had received at least one dose of the anti-SARS-CoV-2 vaccine. The estimated overall and COVID-19 crude annual mortality rates were 22.3% and 5.3%, respectively. CONCLUSION: The absolute number and the prevalence rate of patients on chronic dialysis continue to increase. Most dialysis patients were vaccinated against COVID-19 during the year. The COVID-19 pandemic was associated to the overall mortality rate.

Predictors of arteriovenous fistula maturation in hemodialysis patients: a prospective cohort from an ambulatory surgical center in Joinville, Brazil.

INTRODUCTION: The high rate of arteriovenous fistula maturation failure is a concern in a scenario of growing numbers of patients on hemodialysis. Non-vascular factors tied to maturation success have not been fully discussed. METHODS: This prospective observational cohort study included patients with CKD on dialysis or pre-dialysis prescribed arteriovenous fistula creation for the first time in an ambulatory surgical center in Joinville, Brazil, from January 2021 to July 2021. Anthropometric aspects, sociodemographic characteristics, comorbidities, and vascular parameters observed in Doppler ultrasound were analyzed. Variables associated with maturation were analyzed in multivariate models by logistic regression. RESULTS: Eighty-eight of 145 participants (60.1%) were males. Included patients had a median age of 59 years. Successful arteriovenous fistula maturation occurred in 113 (77.9%) patients. Factors such as increased BMI, hematocrit, arm circumference, and skinfold thickness were associated with lower chances of arteriovenous fistula maturation in univariate analysis. On the other hand, larger vein and artery diameter and fistulas in the more proximal portion of the arm were associated with higher maturation success. In multivariate analysis, smoking and larger skinfold and arm circumference were associated with lower chances of successful maturation. Increased systolic blood pressure and vein diameter were associated with greater chance of success. CONCLUSION: In addition to the vascular parameters assessed in Doppler ultrasonography, factors related to obesity and/or nutritional aspects may influence arteriovenous fistula maturation.

Espiritualidade e dor em pacientes com câncer de mama metastático / Spirituality and pain in patients with metastatic breast cancer / Espiritualidad y dolor en pacientes con cáncer de mama metastásico

Resumo Mediante estudo observacional, transversal e quantitativo que utilizou os instrumentos de avaliação Brief Pain Inventory (dor), Functional Assessment of Chronic Illness Therapy Spiritual Well-Being (bem-estar espiritual) e Beck Depression Inventory - Short Form (depressão), busca-se avaliar a influência da espiritualidade e da depressão na percepção de dor de pacientes acometidas por neoplasia de mama metastática. A idade média foi 57,3 anos e, das 30 participantes, 24 (80%) tratavam-se em serviço público; 17 (57%) tinham diagnóstico de câncer de mama há mais de cinco anos; e 27 (90%) realizavam alguma prática religiosa/espiritual. Pacientes com escore de bem-estar espiritual acima da mediana apresentaram menor escore dos sintomas depressivos (3 vs . 6; p =0,021). Não houve diferença significativa em relação à mediana do escore total do bem-estar espiritual quando estratificado pela mediana da percepção de dor (31,5% vs . 28,5%; p =0,405). Maior manifestação de bem-estar espiritual pode estar relacionada a menores índices de depressão.

Abstract This observational, cross-sectional and quantitative study, by means of the assessment instruments Brief Pain Inventory, Functional Assessment of Chronic Illness Therapy Spiritual Well-Being and Beck Depression Inventory - Short Form, evaluated the influence of spirituality and depression in the pain perception of patients with metastatic breast cancer. Mean age was 57.3 years. Of the 30 participants, 24 (80%) were treated in a public service, 17 (57%) had been diagnosed with breast cancer for more than 5 years, and 27 (90%) were religious or spiritual. Patients with spiritual well-being scores above the median had lower depressive symptom scores (3 vs. 6; p =0.021). The median total score of spiritual well-being showed no significant difference when stratified by median pain perception (31.5% vs. 28.5%; p =0.405). Greater spiritual well-being may be related to lower rates of depression.

Resumen Este estudio observacional, transversal y cuantitativo utilizó los instrumentos Brief Pain Inventory (dolor), Functional Assessment of Chronic Illness Therapy Spiritual Well-Being (bienestar espiritual) y Beck Depression Inventory - Short Form (depresión), para evaluar si la espiritualidad y la depresión influencian en la percepción del dolor en pacientes con cáncer de mama metastásico. La edad promedio fue de 57,3 años; de las 30 participantes, 24 (80%) recibían atención pública; 17 (57%) tenían diagnóstico de cáncer de mama hace más de cinco años; y 27 (90%) solían tener alguna práctica religiosa/espiritual. Aquellas con puntuación de bienestar espiritual superior a la mediana tuvieron una puntuación más baja de síntomas depresivos (3 vs. 6; p =0,021). No hubo diferencias significativas en la mediana de la puntuación total de bienestar espiritual cuando se estratificó por la percepción mediana del dolor (31,5% vs. 28,5%; p =0,405). Una mayor sensación de bienestar espiritual se relacionó a bajas tasas de depresión.

Desafios na Atividade Laboral de Pacientes em Hemodiálise e sua Associação com a Qualidade de Vida / Work Activity Challenges among Hemodialysis Patients and Their Impact on Quality of Life

Grande parte dos pacientes em hemodiálise estão em idade laboral, acarretando um desafio na manutenção do seu trabalho. Realizou-se um estudo transversal em centros de hemodiálise no norte de Santa Catarina, entre dezembro de 2020 a fevereiro de 2021. Incluiu-se pacientes entre 18 e 55 anos em hemodiálise há mais de 3 meses. Avaliou-se aspectos relacionados ao trabalho, sua manutenção após início da hemodiálise e a qualidade de vida através do instrumento SF-36. A condição laboral foi avaliada com relação a qualidade de vida através de regressão logística. Dos 108 pacientes, a média de idade foi 43,34 ±8,88 anos, com mediana do tempo em diálise de 19 meses. Dos participantes, 78,9% estavam trabalhando seis meses antes do início da hemodiálise e 39,8% após 6 meses. Não houve diferença em relação ao sexo, idade e estado civil com relação ao trabalho antes ou após 6 meses do início da hemodiálise. Trabalhar foi associado a uma maior qualidade de vida, mesmo após ajuste para outras variáveis (OR=5,30; 95% IC 1,43-19,61, p=0,013). Conclui-se que existe importante queda da manutenção do emprego após início da hemodiálise. O estímulo a manutenção do trabalho pode favorecer uma melhor qualidade de vida nestes pacientes.

Most patients undergoing hemodialysis are of working age, and this poses a challenge in maintaining their jobs. A crosssectional study was carried out in hemodialysis centers in the north of Santa Catarina, between December 2020 and February 2021. Patients aged between 18 and 55 years old on hemodialysis for more than 3 months were included. Aspects related to work, remaining at their job after starting hemodialysis, and quality of life were evaluated using the SF-36 instrument. Their working situation was evaluated in relation to quality of life through logistic regression. Of the 108 patients, the mean age was 43.34 ± 8.88 years old, with a median time on dialysis of 19 months. Of the participants, 78.9% were working six months before starting hemodialysis and 39.8% were working 6 months after. There was no difference in terms of sex, age, and marital status with regards to work before or after 6 months of starting hemodialysis. Working was associated with a better quality of life, even after adjusting for other variables (OR=5.30; 95% CI 1.43-19.61, p=0.013). It is concluded that there is a significant drop in employment after starting hemodialysis. The stimulus to keep working can favor a better quality of life in these patients.

Incidência de Injúria Renal Aguda em Pacientes Críticos com COVID-19 e Sobrevida em 90 dias: Coorte Retrospectiva de Uma Unidade de Tratamento Intensivo Pública, Joinville/Brasil / Incidence of acute kidney injury in critically ill patients with COVID-19 and 90-day survival: Retrospective Cohort of a Public Intensive Care Unit, Joinville/Brazil

Cerca de um terço dos pacientes com COVID-19 em unidades de terapia intensiva (UTI) apresentam injúria renal aguda (IRA) dialítica. Poucos estudos têm avaliado a sobrevida de pacientes com IRA em UTI exclusivamente pública. O objetivo do estudo foi avaliar a sobrevida intra-hospitalar em 90 dias de pacientes com e sem IRA dialítica internados com COVID-19 grave. Trata-se de uma coorte histórica de um hospital geral em Joinville, Santa Catarina/Brasil. Foram incluídos todos os pacientes admitidos na UTI entre março e dezembro de 2020 com diagnóstico confirmado de COVID-19. Definiu-se IRA como a presença de alteração de função renal aguda com necessidade de hemodiálise. Utilizou-se modelo multivariado por regressão de Cox para avaliar a sobrevida de pacientes com e sem IRA dialítica. Os resultados do estudo demonstraram que dos 187 pacientes incluídos (55,5% homens) com média de idade de 62,8±13,6 anos, 37,4% apresentaram IRA dialítica. Pacientes com IRA dialítica usaram mais drogas vasoativas, tinham maior gravidade na admissão e maior mortalidade (84,3% vs. 63,2%; p=0,002) em relação àqueles sem IRA. O risco de morte nos pacientes com IRA foi maior (RR bruto= 1,60; IC 95% 1,13-2,26; p= 0,007). Após ajustes para idade, sexo, comorbidades e gravidade clínica, a presença de IRA dialítica se manteve associada a uma frequência maior de mortalidade em 90 dias (RR= 1,49; IC 95% 1,03-2.15; p=0,032). A sobrevida de pacientes com COVID-19 grave e IRA dialítica na amostra estudada foi menor em relação a UTIs privadas no Brasil, o que sugere desigualdades no sistema público.

About one third of patients with COVID-19 in intensive care units (ICU) have acute kidney injury (AKI) requiring dialysis. Few studies have evaluated the survival ratel of patients with AKI in exclusively public ICUs. The aim of this study was to evaluate the 90-day in-hospital survival of patients with and without AKI requiring dialysis hospitalized with severe COVID-19. This is a historical cohort of a general hospital in Joinville, Santa Catarina/Brazil. All patients admitted to the ICU between March and December of 2020 with a confirmed diagnosis of COVID-19 were included. AKI was defined by the presence of acute renal function alteration requiring hemodialysis. A multivariate Cox regression model was used to assess the survival of patients with and without AKI requiring dialysis. The results of the study showed that, of the 187 patients included (55.5% men) with a mean age of 62.8±13.6 years, 37.4% had AKI requiring dialysis. Patients with AKI requiring dialysis used more vasoactive drugs, had greater severity on admission and higher mortality rate (84.3% vs. 63.2%; p=0.002) compared to those without AKI. The risk of death in patients with AKI was higher (crude RR= 1.60; 95% CI 1.13-2.26; p= 0.007). After adjustments for age, sex, comorbidities and clinical severity, the presence of AKI requiring dialysis remained associated with a higher frequency of 90-day mortality (RR= 1.49; 95% CI 1.03-2.15; p=0.032). The survival of patients with severe COVID-19 and AKI requiring dialysis in the studied sample was lower compared to private ICUs in Brazil, which suggests inequalities in the public system.

Brazilian Dialysis Survey 2020 / Censo Brasileiro de Diálise 2020

Abstract Introduction: National data on chronic dialysis treatment are essential to support the development of health policies aimed at improving the treatment for thousands of people. Objective: To report epidemiological data from the 2020 Brazilian Dialysis Survey, sponsored by the Brazilian Society of Nephrology. Methods: A survey was carried out in Brazilian chronic dialysis centers using an online questionnaire for the year, covering clinical and epidemiological aspects of patients in a chronic dialysis program, data on dialysis therapy, characteristics of dialysis units and the impact of the COVID-19 pandemic. Results: 235 (28%) of the centers responded to the questionnaire. In July 2020, the estimated total number of patients on dialysis was 144,779. The estimated prevalence and incidence rates of patients per million population (pmp) were 684 and 209, respectively. Of the prevalent patients, 92.6% were on hemodialysis (HD) and 7.4% were on peritoneal dialysis (PD); 23% were on the transplant waiting list. A central venous catheter was used by a quarter of patients on HD. The incidence rate of confirmed COVID-19 between February and July 2020 was 684/10,000 dialysis patients, and the lethality rate was 25.7%. The estimated overall mortality and COVID-19 crude annual mortality rates were 24.5 and 4.2%, respectively. Conclusion: The absolute number of patients on chronic dialysis and prevalence rate continued to increase. The low use of PD as dialysis therapy was maintained and the use of long-term catheters for HD increased. The COVID-19 pandemic contributed to the increase in the overall mortality rate.

Resumo Introdução: Dados nacionais sobre tratamento dialítico crônico são essenciais para apoiar o desenvolvimento de políticas de saúde destinadas a melhorar o tratamento de milhares de pessoas. Objetivo: Relatar dados epidemiológicos do Censo Brasileiro de Diálise 2020, patrocinado pela Sociedade Brasileira de Nefrologia. Métodos: Realizou-se pesquisa em centros brasileiros de diálise crônica utilizando questionário online relativo ao ano, abrangendo aspectos clínicos e epidemiológicos de pacientes em programa de diálise crônica, dados sobre terapia dialítica, características das unidades de diálise e impacto da pandemia COVID-19. Resultados: 235 (28%) centros responderam ao questionário. Em julho de 2020, o número total estimado de pacientes em diálise foi 144.779. As taxas estimadas de prevalência e incidência de pacientes por milhão da população (pmp) foram 684 e 209, respectivamente. Dos pacientes prevalentes, 92,6% estavam em hemodiálise (HD) e 7,4% em diálise peritoneal (DP); 23% estavam na lista de espera para transplante. Cateter venoso central foi utilizado por um quarto dos pacientes em HD. A taxa de incidência de COVID-19 confirmada entre fevereiro e julho de 2020 foi 684/10.000 pacientes em diálise, a taxa de letalidade foi 25,7%. As taxas estimadas de mortalidade geral e mortalidade bruta anual por COVID-19 foram 24,5 e 4,2%, respectivamente. Conclusão: O número absoluto de pacientes em diálise crônica e a taxa de prevalência continuaram a aumentar. O baixo uso de DP como terapia de diálise foi mantido e o uso de cateteres de longa permanência para HD aumentou. A pandemia COVID-19 contribuiu para o aumento da taxa de mortalidade geral.

Distribution of kidney diseases in Joinville, Santa Catarina: analysis of a kidney biopsy data bank between 2008 and 2019 / Distribuição das nefropatias em Joinville, Santa Catarina: análise de um banco de dados de biópsia renal entre 2008 a 2019

Abstract Introduction: Studies based on kidney biopsies are important for the epidemiological understanding of nephropathies. Objective: To describe the main nephropathies diagnosed through renal biopsies, and compare them with regards to gender, time, healthcare insurance and age. Methods: A population-based retrospective study that reviewed all kidney disease diagnoses obtained by biopsy of a native kidney from pathology services between 2008 and 2019 in Joinville, Brazil. Results: Of 778 biopsies performed, 44.5% were primary nephropathies and 28.5% were secondary. The highest prevalence was focal segmental glomerulosclerosis (FSGS) [18.1%], followed by tubulointerstitial nephropathy (TIN) [15.9%] and IgA nephropathy (IgAN) [9.1%]. There was a growing increase in the prevalence of TIN among elderly and uninsured patients over the period. In the multivariate analysis, among the primary glomerulopathies, males had a higher risk for the occurrence of IgAN [OR=2.02; 95% CI 1.13-3.61; p=0.018], as well as being a protective factor for the occurrence of lupus glomerulonephritis (LGN) [OR=0.20, 95% CI 0.08-0.49; p<0.001]. Advancing age and dependence on a public healthcare decreased the likelihood of having a diagnosis of LGN [OR=0.91, 95% CI 0.88-0.94, p < 0.001 and OR=0.45, CI 95 % 0.21-0.96; p = 0.036, respectively]. Patients without private healthcare insurance were more likely to have TIN [OR=1.77, 95%CI 1.16-2.70; p = 0.008]. Conclusion: Sex, age and type of medical healthcare insurance may be related to the occurrence of some nephropathies. The increased risk of TIN in individuals without a private healthcare plan may be an indication of inequalities in health care.

Resumo Introdução: Estudos com base em biópsias renais são importantes para o entendimento epidemiológico das nefropatias. Objetivo: Descrever as principais nefropatias diagnosticadas por meio de biópsias renais e comparar com relação ao gênero, período, plano de saúde e à idade. Métodos: Estudo retrospectivo de base populacional que revisou todos os diagnósticos de doenças renais obtidos por biópsia de rim nativo de serviços de patologias entre 2008 a 2019, em Joinville, Brasil. Resultados: Do total de 778 biópsias realizadas, 44,5% eram nefropatias primárias e 28,5%, secundárias. A maior prevalência foi de glomeruloesclerose segmentar e focal (GESF) [18,1%], seguida por nefropatia tubulointersticial (NTI) [15,9%] e nefropatia IgA (NIgA) [9,1%]. Houve crescente aumento da prevalência de NTI nos pacientes idosos e sem plano de saúde ao longo do período. Na análise multivariada, entre as glomerulopatias primárias, o sexo masculino apresentou maior risco para ocorrência de NIgA [OR=2,02, IC 95% 1,13-3,61; p=0,018], bem como foi um fator de proteção para ocorrência de glomerulonefrite lúpica (GNL) [OR=0,20, IC 95% 0,08-0,49; p < 0,001]. O avançar da idade e a dependência de plano público de saúde diminuíram a chance para o diagnóstico de GNL [OR=0,91, IC 95% 0,88-0,94, p < 0,001 e OR=0,45, IC 95% 0,21-0,96; p = 0,036, respectivamente]. Pacientes sem plano privado de saúde apresentaram mais chance de NTI [OR=1,77, IC 95%1,16-2,70; p = 0,008]. Conclusão: Sexo, idade e tipo de assistência médica podem estar relacionados à ocorrência de algumas nefropatias. O maior risco de NTI em indivíduos sem plano de saúde privado pode ser um indicativo de desigualdades no cuidado à saúde.
