Various seafoods were inoculated with six different strains of Escherichia coli at two concentrations (about 10 and 100 cells/g). The samples were then either homogenized or massaged in buffer using sterile sample bags. E. coli concentration was estimated using the standard procedure (MPN) or microbiological test kits, Petrifilm-VRB and Redigel-VRB, incubated at 45.5°C. The correlation (r) between counts generated using the standard procedure and those from massaged samples, using any of the media employed, was slightly higher than 0.60. Despite the low correlations among procedures, massaging and inoculating microbiological test kits will detect accidental fecal contamination (>600 cells/100 g), but can be modified to detect contamination ≤230 cells/100 g. Probabilities involved in estimated fecal coliform concentration, when few colonies are observed, are discussed.

Background: Venous outflow is the favored access for endovascular management of dialysis fistulas. However, transradial access (TRA) offers advantages in specific clinical scenarios. The study aims to compare the efficacy, feasibility, and safety of TRA and transvenous access (TVA) in the endovascular management of malfunctioning dialysis fistulas, addressing the existing gap in comprehensive literature.

As demanding as dancing en pointe is, no universal standard exists to determine when a ballet dancer is ready to advance to this next level. The goal of this study was to provide preliminarily tested and reliable guidelines for a screening tool that can be used to determine (1) if a dancer is ready for pointe, (2) reasons why a dancer may not be ready, and (3) areas for improvement to guide training and preparation. Seventeen dancers aged 9 to 17 years with a minimum 4 years of ballet and who were either possibly ready for pointe or had been in pointe class less than 3 months participated in this study.

Background: Adults with congenital heart disease (ACHD) can face a lifelong risk of premature cardiovascular events. Endothelial dysfunction and arterial stiffness may be some of the key mechanisms involved. Early identification of endothelial damage in ACHD could be crucial to mitigate the adverse events.

Background: Women who had preeclampsia (a history of preeclampsia) have a >4-fold risk of developing cardiovascular disease compared with women who had an uncomplicated pregnancy (history of healthy pregnancy). Despite the remission of clinical symptoms after pregnancy, vascular endothelial dysfunction persists postpartum, mediated in part by exaggerated Ang II (angiotensin II)-mediated constriction. However, the role of vasodilatory ATRs (Ang II type 2 receptors) in this dysfunction is unknown.
