Frailty Quantified by the "Valencia Score" as a Potential Predictor of Lifespan in Mice.

2017

The development of frailty scores suitable for mice and which resemble those used in the clinical scenario is of great importance to understand human frailty. The aim of the study was to determine an individual frailty score for each mouse at different ages and analyze the association between the frailty score and its lifespan. For this purpose, the "Valencia Score" for frailty was used. Thus, a longitudinal study in mice was performed analyzing weight loss, running time and speed, grip strength and motor coordination at the late-adult, mature and old ages (40, 56 and 80 weeks old, respectively). These parameters are equivalent to unintentional weight loss, poor endurance, slowness, weaknes…

Transit dose comparisons for60Co and192Ir HDR sources

2016

The goal of this study is to evaluate the ambient dose due to the transit of high dose rate (HDR) 60Co sources along a transfer tube as compared to 192Ir ones in a realistic clinical scenario. This goal is accomplished by evaluating air-kerma differences with Monte Carlo calculations using PENELOPE2011. Scatter from both the afterloader and the patient was not taken into account. Two sources, mHDR-v2 and Flexisource Co-60, (Elekta Brachytherapy, Veenendaal, the Netherlands) have been considered. These sources were simulated within a standard transfer tube located in an infinite air phantom. The movement of the source was included by displacing their positions along the connecting tube from …

Clinical Scenario: Unexpected Positive Nodes at Radical Cystectomy

2014

Positive lymph nodes are found in 20–30 % of patients undergoing radical cystectomy for bladder cancer. Their presence is associated with poor survival in the majority. Super-extended lymph node dissection is recommended in the presence of positive lymph nodes to possibly improve oncologic outcome. In patients with unsuspicious lymph nodes, dissection should be performed at least up to the common iliac vessels. Even in the presence of lymph node metastases cystectomy is indicated to reduce local tumor complications. The type of urinary diversion should not be altered by lymph node positivity unless the diversion would otherwise negatively influence the extent of the procedure.

Evaluation of early and late histamine release by three standard volume substitutes

2001

Following meta-analysis [1], the use of colloidal solutions in intensive care medicine is under discussion. Although polygeline [2] and human albumin are known to cause histamine release, other substances eg hydroxyethyl starch were thought to be without effect. Histamine release depends on the clinical scenario, concomitant drugs, infusion speed, duration and amount of infusion. However, there is no information about their effect regarding time periods longer than immediate reactions. This study investigated the histamine releasing effects of three plasma substitutes administered and observed over a longer period of time, simulating many of the clinical scenarios.
