RESUMO A doença renal crônica (DRC) representa um dos principais problemas de saúde pública da atualidade. A dosagem da creatinina sérica e a estimativa da taxa de filtração glomerular (TFG) são as principais ferramentas para avaliação da função renal. Para a estimativa da TFG, existem diversas equações, sendo a mais recomendada a CKD-EPI (Chronic Kidney Disease – Epidemiology). Existem ainda algumas controvérsias com relação à dosagem da creatinina sérica e da estimativa da TFG, uma vez que vários fatores podem interferir nesse processo. Uma importante mudança recente foi a retirada da correção por raça das equações para estimativa da TFG, que superestimavam a função renal, e consequentemente retardavam a implementação de tratamentos como diálise e transplante renal. Neste documento de consenso da Sociedade Brasileira de Nefrologia e Sociedade Brasileira de Patologia Clínica e Medicina Laboratorial são revisados os principais conceitos relacionados à avaliação da função renal, possíveis controvérsias existentes e recomendações para a estimativa da TFG na prática clínica.

ABSTRACT Chronic kidney disease (CKD) represents one of today’s main public health problems. Serum creatinine measurement and estimation of the glomerular filtration rate (GFR) are the main tools for evaluating renal function. There are several equations to estimate GFR, and CKD-EPI equation (Chronic Kidney Disease – Epidemiology) is the most recommended one. There are still some controversies regarding serum creatinine measurement and GFR estimation, since several factors can interfere in this process. An important recent change was the removal of the correction for race from the equations for estimating GFR, which overestimated kidney function, and consequently delayed the implementation of treatments such as dialysis and kidney transplantation. In this consensus document from the Brazilian Societies of Nephrology and Clinical Pathology and Laboratory Medicine, the main concepts related to the assessment of renal function are reviewed, as well as possible existing controversies and recommendations for estimating GFR in clinical practice.

ABSTRACT Purulent pericarditis is rare condition in the modern era of antibiotics. However, it is a serious condition as it has an accelerated progression and is difficult to diagnose due to its nonspecific clinical presentation, resulting in high mortality. Herein, we present a case in which a 36-year-old male patient with otherwise unremarkable medical history developed abdominal sepsis complicated by purulent pericarditis post-appendectomy. While the initial clinical presentation was not compatible with the classic signs of purulent pericarditis, the diagnosis was made using electrocardiography (ST elevation/PR depression) and point-of-care ultrasonography (pericardial effusion). The condition was successfully managed with pericardial drainage and broad-spectrum antibiotics. The present case reinforces and reiterates the need for high diagnostic suspicion and careful clinical reasoning in the diagnosis of purulent pericarditis. Furthermore, it highlights the applicability of point-of-care ultrasonography in the diagnosis of the same. antibiotics However mortality Herein 36yearold yearold 36 year old postappendectomy. postappendectomy post appendectomy. appendectomy post-appendectomy ST elevationPR elevation PR depression pointofcare point care effusion. effusion . effusion) broadspectrum broad spectrum Furthermore same 3

Abstract Objectives: The authors aim to evaluate the ‘‘point-of-care’’ transfontanellar ultrasound (TU) as an extension to pediatric physical examination and suggest a TU teaching protocol. Methods: The students were randomly divided into two groups, group A (12 participants) and group B (15 participants). The first group only received theoretical training, while the second group received theoretical and practical training. A third group, group C, included 15 pediatricians and interns who also received theoretical and practical training. All the participants underwent multiple-choice testing before and after a four-hour short course on TU. Six months later, another evaluation was performed to analyze the retained knowledge. Furthermore, a questionnaire based on the Likert scale was administered to evaluate satisfaction. Results: The cognitive evaluation (maximum score = 10 points) before and after training increased in group A from 4,0 ± 1,04 to 7,5 ± 1,2 (p < 0.001) and, 6 months later, to 6,5 ± 1,16 (p < 0.003); in group B from 3,8 ± 1,24 to 8,8 ± 1,01 (p < 0.001) and, 6 months later, to 8,46 ± 0,91 (p < 0.001); and in group C from 6,0 ± 0,75 to 9,0 ± 0,75 (p < 0.001) and, 6 months later, to 8,8 ± 0,77 (p < 0.001). The average satisfaction estimated by the Likert scale was over 80% for all questions. Conclusion: Cognitive assessment before and after classes and training reveals progress in learning, with knowledge retention in 6 months. Theoretical-practical courses are well accepted.

ABSTRACT Point-of-Care Ultrasound (POCUS) has been gaining momentum as an extension to physical examination in several specialties. In nephrology, POCUS has generally been used in a restricted way in urinary tract evaluation. We report the case of a patient with nephrotic syndrome secondary to amyloidosis, previously diagnosed by renal biopsy, who was oligosymptomatic when seen the an outpatient clinic, where the POCUS, focused on the heart, lung and abdomen, revealed anasarca, pulmonary congestion and cardiac changes suggestive of cardiac amyloidosis. After evaluation by the cardiology and hematology services, the diagnosis of AL amyloidosis with cardiac involvement was confirmed. This case emphasizes the importance of extending the physical examination using POCUS, which, ideally, should not be restricted to the urinary tract.

RESUMO Os canabinoides compreendem os endocanabinoides, fitocanabinoides e os canabinoides sintéticos e desempenham ações no sistema nervoso central e periférico. Uma quantidade enorme de publicações tem sido lançada nos últimos anos, embora a cannabis seja conhecida por milênios. Os Departamentos Científicos da Academia Brasileira de Neurologia descreveram as evidências do uso médico em suas áreas. A literatura está em constantes mudanças e possíveis novas evidências podem surgir nos próximos dias ou meses. A prescrição dessas substâncias deve ser discutida com os pacientes e suas famílias, com conhecimento sobre eventos adversos e sua eficácia.

ABSTRACT Cannabinoids comprehend endocannabinoids, phytocannabinoids, and synthetic cannabinoids, with actions both in the central and peripherical nervous systems. A considerable amount of publications have been made in recent years, although cannabis has been known for over a thousand years. Scientific Departments from the Brazilian Academy of Neurology described evidence for medical use in their areas. Literature is constantly changing, and possible new evidence can emerge in the next days or months. Prescription of these substances must be discussed with patients and their families, with knowledge about adverse events and their efficacy.

Abstract Background Cardiovascular disease (CVD) is commonly associated with chronic kidney disease (CKD). These diseases have a significant impact on life expectancy. Individuals with CKD are more likely to die from CVD than to progress to end-stage kidney disease. Objective To assess cardiovascular risk factors of patients with CKD under conservative treatment. Methods This was an observational, cross-sectional study. Socioeconomic, anthropometric, biochemical, and physical inactivity data were assessed, and 10-year risk for CVD were estimated using the Framingham Score in patients with CKD under conservative treatment. For statistical analysis, the Student’s t-test and Pearson’s chi-square test were performed. Results A total of 172 individuals were evaluated, 57% of whom were male, with an average age of 68.85 ± 11.41 years. The prevalence of hypertension and diabetes were 87.2% and 53.5%, respectively; 62.2% were physically inactive; 9.9% of men were smokers and 12.8% consumed alcohol. According to BMI, 82.4% of adults <60 years old and 60.6% of those older than 60 years were overweight. High waist circumference and a high waist-hip ratio were highly prevalent in females (91.9% and 83.8%, respectively) and males (64.3% and 39.8%, respectively); 92.4% had a high body fat percentage and 73.3% high uric acid levels. According to the Framingham score, 57% have a medium or high risk of developing CVD in 10 years. Conclusion There was a high prevalence of cardiovascular risk factors in the population studied. The assessment of cardiovascular risk factors in patients with CKD makes it possible to guide the conduct of health professionals to prevent mortality from cardiovascular causes.

SUMMARY OBJECTIVE: Free intra-abdominal fluid describes an accumulation of free fluid in the peritoneal cavity. It has different etiologies, but it frequently constitutes a meaningful clinical sign. In this study, the authors interrogate whether abdominal ultrasound augments the medical students’ ability to identify free intra-abdominal fluid. METHODS: Thirty-one medical students without any previous formal ultrasound training were subjected to cognitive assessment before and after four and a half-hour of theoretical lecture and hands-on course about the diagnosis of free intra-abdominal fluid by physical examination and abdominal ultrasound. The hands-on sessions were done in healthy volunteers with a simulated peritoneal catheter and in patients treated with peritoneal dialysis with different amounts of dialysate in their cavity. RESULTS: The cognitive assessment before and after the course increased from 6.7±2.3 to 11.6±1.1 points (p<0.0001). The sensitivity, specificity, and accuracy in the diagnosis of free intra-abdominal fluid were higher when students used abdominal ultrasound. The students agree with the inclusion of abdominal ultrasound in the diagnose of free intra-abdominal fluid in the undergraduate curriculum. CONCLUSIONS: This study demonstrates that incorporating abdominal ultrasound is feasible and improves medical students’ short-time competency in performing and interpreting the findings diagnostic of free intra-abdominal fluid.

Resumo Introdução: Avaliar a associação da espessura do músculo adutor do polegar (EMAP) com o estado nutricional e propor pontos de corte para depleção de massa muscular em idosos portadores da doença renal crônica (DRC) em tratamento conservador. Metodologia: Estudo epidemiológico, delineamento transversal, incluindo portadores de DRC estágios 3 a 5, acima de 60 anos. Obteve-se dados socioeconômicos, clínicos, prática de atividade física e antropométricos. A EMAP foi descrita e comparada de acordo com o estágio da DRC, dados socioeconômicos, atividade física e estado nutricional e correlacionada com idade, taxa de filtração glomerular e variáveis antropométricas. Foram produzidas curvas Receiver Operating Characteristic (ROC), considerando como padrão de referência a classificação do índice de tecido magro. O ponto de corte foi definido pelo índice Youden. Resultados: Avaliou-se 137 indivíduos. A EMAP foi inferior nos desnutridos e/ou com depleção de massa muscular; no sexo masculino foi superior nos praticantes de atividade física (p<0,05). A medida se correlacionou moderadamente com IMC, circunferência da panturrilha e braquial, tecido de massa magra, índice de tecido magro e massa celular corporal (r<0,7), e negativamente com a idade (r=-0,34). A análise da curva ROC determinou pontos de corte de 15,33 mm para o sexo feminino e 20,33 mm para o masculino, com acurácia de 72,22% e 62,50%, respectivamente. Conclusão: A EMAP serve para estimar a massa muscular, e o ponto de corte sugerido é útil para afastar a probabilidade de depleção de massa muscular. Recomenda-se que seja utilizada de forma complementar na avaliação nutricional.

Abstract Introduction: Evaluate the association between the thumb adductor muscle thickness and the patient's nutritional status, and propose cutoff points for muscle mass depletion in elderly patients with chronic kidney disease (CKD) under conservative treatment. Epidemiological and cross-sectional study, including patients with CKD stages 3 to 5, older than 60 years. Socioeconomic, clinical, physical activity and anthropometric data was obtained. TAMT was described and compared according to CKD stage, socioeconomic data, physical activity, nutritional status and correlated with age, glomerular filtration rate and anthropometric variables. Receiver Operating Characteristic (ROC) curves were produced, considering the lean tissue index classification as reference. The cut-off point was defined by the Youden index. Results: We evaluated 137 individuals. The TAMT was lower in malnourished and/or depleted muscle mass individuals; among males it was higher among those who practiced physical activities (p <0.05). This measure was moderately correlated with BMI, calf and brachial circumferences, lean body tissue, lean tissue index and body cell mass (r <0.7); negatively with age (r = -0.34). The ROC curve analysis determined cut points of 15.33 mm for females and 20.33 mm for males, with 72.22% and 62.50% accuracy, respectively. Conclusion: TAMT is used to estimate muscle mass and we suggest the cutoff point is useful to rule out the likelihood of muscle mass depletion. It is recommended that it be used in a complementary way in nutritional assessment.

Abstract Serum hepcidin levels may increase in response to infection and inflammation. The present study investigated the effect of nonsurgical periodontal therapy (NSPT) on levels of serum hepcidin, inflammatory markers, and iron markers. An interventional study was conducted on 67 patients (age 30–65 years) without other diseases, except for chronic periodontitis (CP). Patients were allocated to either CP or control groups. The CP group received supragingival and subgingival scaling and root planing procedures, whereas the control group received supragingival scaling. Probing depth (PD), bleeding on probing, clinical attachment level (CAL), visible plaque index (VPI), serum hepcidin and interleukin-6 (IL-6) levels, high-sensitivity C-reactive protein (hs-CRP), hematological markers, and iron markers were measured at baseline and at 90 days after NSPT. The CP group had statistically significant lower mean values for mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) (p ≤ 0.05). The control group had statistically significant reductions in hemoglobin, hematocrit, MCV, and MCH (p ≤ 0.05). Serum hepcidin, IL-6, and erythrocyte sedimentation rate (ESR) levels were significantly decreased in both groups after NSPT. Periodontal markers were more markedly reduced in the CP group compared with the control group (p ≤ 0.05). These findings suggest that NSPT may reduce the serum levels of IL-6, hepcidin, and periodontal parameters.

RESUMO Introdução: A fístula arteriovenosa (FAV) é considerada o acesso vascular padrão ouro para hemodiálise crônica, e sua falha prediz taxas mais altas de morbimortalidade. Objetivos: 1) Avaliar a taxa de sucesso da FAV criada por um nefrologista e 2) identificar variáveis clínicas, laboratoriais e demográficas que influenciam a patência da FAV. Métodos: Estudo de coorte retrospectivo de 101 pacientes com doença renal crônica, totalizando 159 FAVs criados por um nefrologista entre junho de 2010 e junho de 2013. Resultados: Das FAVs criadas, 124 (78%) apresentaram patência imediata e 110 (62,9%) apresentaram patência tardia. A hemoglobina (10-12 g/dL) foi a única variável relacionada à patência tardia da FAV (p = 0,05). A pressão arterial elevada no momento da cirurgia foi associada a um menor número de procedimentos por paciente (p = 0,001). A FAV proximal ocorreu com maior frequência em pacientes com dois acessos confeccionados (p = 0,03). A taxa de sucesso da FAV foi semelhante à relatada anteriormente na literatura. Conclusão: O nível de hemoglobina no intervalo recomendado tem um impacto favorável na perviedade tardia da FAV e pressão arterial elevada durante a cirurgia no menor número de acessos vasculares por paciente. A alta taxa de sucesso indica que ela pode ser feita por nefrologistas treinados.

ABSTRACT Introduction: Arteriovenous fistula (AVF) is considered the gold standard vascular access for chronic hemodialysis, and its failure predicts higher morbidity and mortality rates. Objective: 1) To evaluate the success rate of AVF created by a nephrologist and 2) to identify clinical, laboratory, and demographic variables that influence AVF patency. Methods: A retrospective cohort study of 101 patients with chronic kidney disease for a total of 159 AVF created by a nephrologist between June 2010 and June 2013. Results: Of the AVFs created, 124 (78%) displayed immediate patency and 110 (62.9%) displayed late patency. Hemoglobin (10-12 g/dL) was the only variable related to late AVF patency (p = 0.05). An elevated blood pressure at time of surgery was associated with a lower number of procedures per patient (p = 0.001). Proximal AVF occurred more frequently in patients with dual access (p = 0.03). The AVF success rate was similar to those previously reported in the literature. Conclusion: Hemoglobin level in the recommended range has a favorable impact on late AVF patency and elevated blood pressure during surgery on the lower number of vascular accesses per patient. The high success rate indicates that it can be placed by trained nephrologists.

ABSTRACT Objective: The aim of this study is to systematically review the scientific findings about the efficacy of the measure of the Adductor Pollicis Muscle Thickness for nutritional assessment of individuals in various clinical conditions. Method: Systematic review study performed according to the methodology Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Results: 13 original articles published between 2004 and 2016 were included. The measure was associated/correlated to parameters of nutritional status (such as weight, body mass index and Global Subjective Assessment) and muscle mass markers (such as circumference brachial muscle circumference, brachial muscle area, calf circumference, and muscle mass). All these correlations were weak or moderate. Conclusion: The measurement can be used in different populations, being able to estimate nutritional status and muscle mass. However, it is suggested that it be used in a complementary way to the nutritional evaluation, not constituting a single diagnostic/monitoring parameter.

RESUMEN Objetivo: Revisar de forma sistemática las constataciones científicas acerca de la eficacia de la medida de la Espesura del Músculo Aductor del Pulgar para evaluación nutricional de los individuos bajo diversas condiciones clínicas. Método: Estudio de revisión sistemática, realizado conforme la metodología Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Resultados: Se incluyeron 13 artículos originales publicados entre 2004 y 2016. La medida se presentó asociada/correlacionada a los parámetros de evaluación del estado nutricional (peso, índice de masa corporal y Evaluación Subjetiva Global) y a los marcadores de masa muscular (como circunferencia braquial, circunferencia muscular braquial, área muscular braquial, circunferencia de la pantorrilla y masa muscular). Todas estas correlaciones fueron débiles o moderadas. Conclusión: La medida puede ser utilizada en diferentes poblaciones, siendo capaz de estimar el estado nutricional y la masa muscular. Sin embargo, se sugiere que se emplee de forma complementaria la evaluación nutricional, no constituyendo un parámetro único de diagnóstico/monitoreo.

No entanto, sugere-se que seja empregada de modo complementar à avaliação nutricional, não constituindo um parâmetro único de diagnóstico/monitoramento.
