Background And Aims: Race coefficients (RC) in equations to estimate glomerular filtration rate (GFR) have been highly questioned. We aimed to evaluate the performance of three equations, namely 2009 Chronic Kidney Disease Epidemiology Collaboration (2009 CKD-EPI), 2021 CKD-EPI, and European Kidney Function Consortium (EKFC) in self-reported Black and White Brazilians.
Materials And Methods: Our cross-sectional study compared estimated GFR (eGFR) with Cr-EDTA measured GFR (mGFR) in healthy adults, patients with type 2 diabetes mellitus with or without chronic kidney disease (CKD), and in non-diabetic individuals with CKD.
Background: Respiratory sarcopenia is characterized by the weakness of respiratory muscles associated with sarcopenia due to aging or systemic diseases such as chronic kidney disease (CKD). Patients with CKD undergoing dialysis are particularly susceptible to respiratory muscle weakness caused by factors such as fluid overload and electrolyte imbalance. This weakness not only affects ventilation but also impairs oxygen uptake and delivery to muscle tissue, potentially leading to severe sarcopenia.

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.
Introduction: Patients on renal replacement therapy (RRT) and kidney transplant recipients (KTR) present multiple factors that may increase the risk of death from coronavirus disease 2019 (COVID-19). This study aimed to evaluate the incidence and impact of COVID-19 in RRT patients and KTRs.
Methods: Between March 2020 and February 2021, we monitored the RRT population of thirteen dialysis facilities that refer patients for transplantation to our center, a tertiary hospital in Southern Brazil.
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.
Objective: To evaluate the incidence of hypothermia in patients undergoing continuous renal replacement therapy in the intensive care unit. As secondary objectives, we determined associated factors and compared the occurrence of hypothermia between two modalities of continuous renal replacement therapy.
Methods: A prospective cohort study was conducted with adult patients who were admitted to a clinical-surgical intensive care unit and underwent continuous renal replacement therapy in a high-complexity public university hospital in southern Brazil from April 2017 to July 2018.
Introduction: National data on chronic dialysis treatment are essential for the development of health policies that aim to improve the treatment of patients.
Objective: To present data from the Brazilian Dialysis Survey 2019, promoted by the Brazilian Society of Nephrology.
Methods: Data collection from dialysis units in the country through a completed online questionnaire for 2019.
Introduction: National data on chronic dialysis treatment are essential for the development of health policies that aim to improve patient treatment.
Objective: To present data from the Brazilian Society of Nephrology on patients with chronic dialysis for kidney disease in July 2018, making a comparative analysis of the past 10 years.
Methods: Data collection from dialysis units, with filling in an online questionnaire for 2018.
Objective: The aim of this cross-sectional study was to evaluate the association between periodontitis and different severities of chronic kidney disease (CKD) in predialytic patients.
Materials And Methods: Demographic, socioeconomic, and medical data of 139 patients from the nephrology service of one university hospital in Porto Alegre, Brazil, were obtained through interview and clinical records. Full-mouth six-sites per tooth periodontal examinations were performed.
Introduction: Having national data on chronic dialysis is essential in treatment planning.
Objective: To present data of the survey from the Brazilian Society of Nephrology on patients with chronic kidney disease on dialysis in July 2017.
Methods: Data was collected from dialysis units in Brazil.
Introduction: The methods and initial results of a web-based platform to collect data from patients receiving maintenance dialysis in Brazil are reported.
Methods: Companies providing management software for dialysis centers adapted their system to comply with a formulary of the Brazilian Society of Nephrology. Baseline and follow-up individual patients' data were transmitted via Internet on monthly bases to the coordinating center from 2011 to 2017.
Introduction: National chronic dialysis data are important for the treatment planning.
Objective: To report data of the annual survey of the Brazilian Society of Nephrology about chronic kidney disease patients on dialysis in July 2016.
Methods: A survey based on data of dialysis centers from the whole country.
Introduction: Hemodialysis contributes to increased oxidative stress and induces transitory hypoxemia. Compartmentalization decreases the supply of solutes to the dialyzer during treatment. The aim of this study was to investigate the acute effects of intradialytic aerobic exercise on solute removal, blood gases and oxidative stress in patients with chronic kidney disease during a single hemodialysis session.

Introduction: National chronic dialysis data have had impact in the treatment planning.
Objective: To report data of the annual survey of the Brazilian Society of Nephrology about chronic kidney disease patients on dialysis in July 2013 and compare with 2011-12.
Methods: A survey based on data of dialysis units from the whole country.
Background: Chronic kidney disease has become a public health problem worldwide. Its terminal stage requires renal replacement therapy--dialysis or transplantation--for the maintenance of life, resulting in high economic and social costs. Though the number of patients with end-stage renal disease treated by dialysis in Brazil is among the highest in the world, current estimates of incidence and prevalence are imprecise.

However, this point has not been tested in some ethnic groups. This study investigated the performance of MDRD and CKD-EPI equations in South Brazilian individuals.

The text does not correspond to their opinion, it is a brief presentation of guidelines that could be useful in clinical practice.

Objective: To report data of the annual survey of the Brazilian Society of Nephrology about chronic kidney disease patients on dialysis in July 2012.
Methods: A survey based on data of dialysis units from the whole country.
Patients on hemodialysis (HD) show changes in muscle structure and function reducing their functional capacity. This study was conduted to assess the effects of respiratory muscle training (RMT) and peripheral muscle training (PMT) during dialysis on functional parameters, inflammatory state, and quality of life (QoL) in patients on HD. Randomized controlled trial included 39 patients on HD, and they were divided into three groups: RMT (n = 11), PMT (n = 14), and controls (C, n = 14).

Aim: To describe the results of the dialysis census of the Brazilian Society of Nephrology for 2011 and observed trends from 2000 to 2011.
Methods: A survey was conducted using questionnaire filled online by the dialysis units, with July as reference month for estimates.
Introduction: Patients with chronic kidney disease (CKD) have reduced physical and functional capacity when compared with the general population. Hemodialysis (HD) restricts patients activities, favoring a sedentary lifestyle and leading to functional limitations. HD patients are less active, present low exercise tolerance and have high physical deconditioning.
