Two-in-One Protocol: Simultaneous Small-Pore and Ultrasmall-Pore Peritoneal Tra...

BACKGROUND: Reduced free water transport (FWT) through ultrasmall pores contributes to net ultrafiltration failure (UFF) and should be seen as a sign of more severe functional deterioration of the peritoneal membrane. The modified peritoneal equilibration test (PET), measuring the dip in dialysate Na concentration, estimates only FWT. Our aim was to simultaneously quantify small-solute transport, FWT, and small...

Peritoneal membrane phosphate transport status: a cornerstone in phosphate hand...

BACKGROUND AND OBJECTIVES: Phosphate control impacts dialysis outcomes. Our aim was to define peritoneal phosphate transport in peritoneal dialysis (PD) and to explore its association with hyperphosphatemia, phosphate clearance (PPhCl), and PD modality. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Two hundred sixty-four patients (61% on continuous ambulatory PD [CAPD]) were evaluated at month 12. PPhCl w...

Avaliação da ingestão alimentar de indivíduos idosos com demência

A alimentação é uma das actividades básicas da vida diária que se torna um problema comum em idosos, especialmente naqueles com demência. Os principais factores que podem interferir com esta actividade básica são o ambiente onde ocorrem as refeições, a incapacidade cognitiva para iniciar e prosseguir estratégias de alimentação de uma forma eficaz, o declínio de habilidades neuromotoras e a presença de deficits ...

Confined Placental Mosaicism in Chorionic Vilus Sampling - Case Report

Objectives: Chorionic Vilus Sampling (CVS) has several advantages over amniocentesis: it may be performed at an earlier gestational age, the results are quicker to obtain and there’s a lower miscarriage risk – 1%. However, the higher prevalence of discrepant fetal and vilus sampling material’s karyotype findings is a disadvantage of this technique – 0.5%. This is caused, amongst other causes, by placental mosai...
