Lead in synthetic and municipal drinking water varies by field versus laboratory analysis.

Water lead measurements by two field analyzers, relying on anodic stripping voltammetry (ASV) and fluorescence spectroscopy, were compared to reference laboratory measurements by inductively coupled plasma mass spectrometry (ICP-MS) in progressively complex datasets (phases A, B, C), to assess field analyzer performance. Under controlled laboratory quantitative tests of dissolved lead within the field analysis range and optimal temperature range, lead recoveries by ASV ranged within 85-106 % of reference laboratory values (corresponding linear model: y = 0.96x, r = 0.

Performance and safety of femoral central venous catheters in pediatric autologous peripheral blood stem cell collection.

Introduction: Autologous peripheral blood hematopoietic progenitor cell collection (A-HPCC) in children typically requires placement of a central venous catheter (CVC) for venous access. There is scant published data regarding the performance and safety of femoral CVCs in pediatric A-HPCC.

Methods: Seven-year, retrospective study of A-HPCC in pediatric patients collected between 2009 and January 2017.

Procedure-related complications and adverse events associated with pediatric autologous peripheral blood stem cell collection.

Introduction: Autologous peripheral blood hematopoietic progenitor cell collection (A-HPCC) in pediatric patients is considered relatively safe although technically challenging. Very little is known regarding the incidence, risk factors and impact of procedure-related adverse events (AE) on pediatric A-HPCC outcomes.

Methods: Prospective 4.
