Hypokalemia and hyperkalemia: Two Sides of the Same Coin
Tavares,Joana; Mosca,Sara; Faria,Maria do Sameiro; Mota,ConceiçãoAbstract Introduction: Potassium (K+) is the main intracellular cation and is crucial for normal cellular function, especially during children’s development and growth course. Changes in the homeostatic mechanisms of potassium regulation can lead to hypokalemia or hyperkalemia. Objective: This study aimed to provide a narrative review of this common, yet complex, condition of the clinical practice. Development/...
Association between severe chronic kidney disease defined by cystatin-c and cre...
Tavares,Joana; Santos,Josefina; Silva,Filipa; Oliveira,João; Malheiro,Jorge; Campos,Andreia; Cabrita,AntónioABSTRACT Introduction: Estimated glomerular filtration rate (eGFR) based on serum cystatin-C (sCys) seems as accurate as when based on serum creatinine (sCr), but sCys seems a better predictor of adverse outcomes. We aimed to study whether sCys could be a reliable tool for the prediction of adverse outcomes in elderly patients with severe chronic kidney disease (CKD). Methods: A group of 348 elderly patients wi...
Acute hyperammonemic encephalopathy - an indication for an extracorporeal depur...
Silva,Filipa; Tavares,Joana; Castro,Ana; Guimas,Arlindo; Freitas,Cristina; Pimentel,João Pedro; Cabrita,AntónioABSTRACT Introduction: Ammonia is a resultant molecule from the protein metabolism that can be neurotoxic when present in high concentrations, causing brain edema and encephalopathy. Extracorporeal blood purification technique (EBPT) can play a role in reducing both ammonia and urea blood levels. However, there are no specific guidelines for its use in hyperammonemia, due to its low incidence and scarce literat...
Does Cystatin C have a role as metabolic surrogate in peritoneal dialysis beyon...
Moreira,Carla Leal; Cunha,Liliana; Correia,Sofia; Silva,Filipa; Castro,Ana; Tavares,Joana; Carvalho,Maria João; Oliveira,José Carlos; Santos,OlíviaABSTRACT Introduction: It has been suggested that cystatin C levels are modified by obesity and inflammation. Furthermore, cystatin C has been associated with cardiovascular events and mortality outcomes. Aim: To study the association of cystatin C with the metabolic profile and cardiovascular disease of peritoneal dialysis patients. Methods: Data collected included clinical, laboratorial, and multifrequency bi...
Urgent-Start Peritoneal Dialysis - a viable option?: A case report and literatu...
Tavares,Joana; Silva,Filipa; Lima,Anna; Carvalho,Maria João; Cabrita,António; Rodrigues,AnabelaBackground: Many patients with end-stage renal disease start renal replacement therapy in an unplanned manner. The vast majority initiate hemodialysis by a central venous catheter, since its use is more widespread and available. This technique is associated with a high risk of infection and damage of the vascular patrimony associated with the use of central veins. Urgent-start peritoneal dialysis comes as an al...
SARS-CoV-2 infection in hemodialysis patients: Preliminary data from a Portugue...
Tavares,Joana; Dias,Bruno Fraga; Oliveira,João Pedro; Sala,Inês; Silva,Filipa; Castro,Ana; Freitas,Cristina; Fonseca,Tomás; Pimentel,João PedroBackground: In December 2019, a new form of coronavirus was identified (COVID-19) and quickly became a worldwide pandemic. Previous data reported a more severe disease in older patients, with high comorbidities, which are common features in hemodialysis patients. Scarce data is available about the clinical presentation and outcomes in this population. For this reason, we aim to report the characteristics of COV...
Online hemofiltration in incremental dialysis prescription
Correia,Sofia Oliveira; Silva,Filipa Santos; Tavares,Joana; Cabrita,António; Queirós,JoséIncremental dialysis is increasingly recognized as a safe and beneficial method of initiating dialysis. Different centers use distinct prescription methods. We discuss the advantages of incremental hemodialysis and the potential benefit of preserving residual renal function as we present our experience. We reviewed the data from 20 incident patients, with a mean follow-up of 9.5 months, who started dialysis wit...
Signet Ring Cell Carcinoma, Ileal Crohn Disease or Both: A Case of Diagnostic C...
Carvalho,Joana R.; Tavares,Joana; Goulart,Inês; Santos,Paula Moura dos; Vitorino,Emília; Ferreira,Cristina; Serejo,Fátima; Velosa,JoséSignet ring cell carcinoma is a rare form of adenocarcinoma that predominantly affects the stomach. Signet ring cell carcinoma originated from the ileum is extremely rare and the prognosis is poor. We present a case of small bowel obstruction with features suggesting Crohn disease of the ileum. The symptoms were chronic diarrhea and abdominal pain with a family history of inflammatory bowel disease. The patient...
