Background: 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 ...
This study aimed to characterize endometrial cancer regarding cancer stem cells (CSC) markers, regulatory and differentiation pathways, tumorigenicity and glucose metabolism. Endometrial cancer cell line ECC1 was submitted to sphere forming protocols. The first spheres generation (ES1) was cultured in adherent conditions (G1). This procedure was repeated and was obtained generations of spheres (ES1, ES2 and ES3...
The anticancer effects of human amniotic membrane (hAM) have been studied over the last decade. However, the action mechanisms responsible for these effects are not fully understood until now. Previously results reported by our team proved that hAM is able to induce cytotoxicity and cell death in hepatocellular carcinoma (HCC), a worldwide high incident and mortal cancer. Therefore, this experimental study aime...
Introduction: Diabetes mellitus is a leading cause of chronic renal failure, challenging therapy strategies. Patients with diabetes may benefit from peritoneal dialysis (PD) but higher technique failure is feared. Our purpose was to critically evaluate clinical outcomes of this modality in diabetics, in order to find quality improvement strategies in these risk patients. Methods: A registry-based study of 432 i...
Background: Modelling competing risks is an essential issue in Nephrology Research. In peritoneal dialysis studies, sometimes inappropriate methods (i.e. Kaplan-Meier method) have been used to estimate probabilities for an event of interest in the presence of competing risks. In this situation a competing risk analysis should be preferable. The objectives of this study are to describe the bias resulting from th...
Peritonitis remains a common complication of peritoneal dialysis (PD). The aim of this study was to analyze, in a PD center, long-term temporal trends in peritonitis rates, microbiology and outcomes. We treated 588 cases of peritonitis that occurred during 11,833.6 months at risk. Y-set and twin-bag disconnecting systems were introduced in 1990, mupirocin at the exit site in 2000 and fluconazole prophylaxis in ...
Procedeu-se a uma revisão da literatura sobre os conceitos actuais de tratamento da endometriose associada a infertilidade. A terapêutica médica isolada não parece ser útil no tratamento da infertilidade. A cirurgia laparoscópica permite melhorar a probabilidade de ocorrência de gravidez espontânea ou com auxílio de técnicas de procriação medicamente assistida (PMA). Um estudo prospectivo demonstrou o efeito be...
O Síndrome de Klinefelter é uma das causas mais frequentes de hipogonadismo masculino. As manifestações clínicas do Síndrome de Klinefelter variam consideravelmente de indivíduo para indivíduo. Assim, alguns doentes têm alterações no desenvolvimento dos caracteres sexuais secundários, enquanto que outros não se distinguem de indivíduos saudáveis. Os autores avaliaram a variabilidade de apresentação clínica em 2...
