Ex vivo perfusion, arteriography, and autotransplantation procedures for kidney salvage
Three kidneys with arterial lesions that would have been difficult or impossible to repair by standard vascular reconstruction were removed, perfused by the Belzer technique, and returned to host after partial or complete autotransplantation. The fact that kidneys can be studied, dissected, repaired, and constantly salvaged with this technique should have important implications in several aspects of urologic operations
THE EFFECTS OF FIELD EMITTED ELECTRONS ON RF SURFACE
The ever-growing demand for higher RF gradients has
considerably increased the risk of breakdown in
accelerating structures. Field emission is the most
common form of RF breakdown that generates free
electrons capable of inflicting irreversible damages on the
RF surface. This paper presents a systematic experimental
and simulation programme to understand possible sources
and their influence on RF cavity operatio
Flow rate accuracy of infusion devices within healthcare settings: a systematic review
Background: One in five patients admitted to the hospital treated with intravenous (IV) fluid therapy suffer complications due to inappropriate administration. Errors have been reported in 13-84% of the preparation and administration of IV medications. The safe delivery of IV fluids requires precise rate administration.
Objectives: This systematic review aims to determine the accuracy of infusion sets and devices and examine the factors that affect the flow rate accuracy of devices.
Data sources and methods: Six databases (CINAHL, MEDLINE PubMed, EMBASE, Web of Science and Cochrane Database of systematic reviews) were systematically searched. Search terms included infusion pumps, infusion devices, flow rate accuracy, fluid administration rate, gravity-led infusion set and fluid balance. Studies were included if they examined infusion devices' flow rate accuracy and drop rates for fluids or non-oncological drugs. Findings were tabulated and synthesised qualitatively. The quality of the studies was examined based on the design of the studies due to their heterogeneity.
Results: Eight studies were included: Four studies were conducted on human subjects in the hospital environment; studies recruited 182 participants between the ages of 18 and 94 years. Two studies examined flow rate accuracy in recruited patients across 509 observations and 2387 drip hours. No trials prospectively assessed the accuracy of infusion pumps in the clinical domain, and no studies were reported on patient safety outcomes. Four studies examined the impact of mechanical and physiological factors on the flow rate accuracies of infusion devices. Height and back pressure simulated vibrating conditions, the viscosity of IV fluid and the positions of patients were reported to have a significant impact on infusion volume and flow rates of infusion devices. Additionally, giving sets that vary from the manufacturer's specifications are reported to increase error percent by 10-20%.
Conclusion: Infusion devices are an important source of error in administering IV fluids. Yet, there needs to be more prospective trial data to support their clinical accuracy and the impact on patient outcomes. Future flow variability and accuracy studies should capture their impact on patient safety and clinical outcomes

Why democratize bioinformatics?
Network bioinformatics and web-based data collection instruments have the capacity to improve
the efficiency of the UK’s appropriately high levels of investment into cardiovascular research.
A very large proportion of scientific data falls into the long-tail of the cardiovascular research
distribution curve, with numerous small independent research efforts yielding a rich variety of
specialty data sets. The merging of such myriad datasets and the eradication of data silos, plus
linkage with outcomes could be greatly facilitated through the provision of a national set of
standardised data collection instruments—a shared-cardioinformatics library of tools designed
by and for clinical academics active in the long-tail of biomedical research. Across the
cardiovascular research domain, like the rest of medicine, the national aggregation and
democratization of diverse long-tail data is the best way to convert numerous small but
expensive cohort data sources into big data, expanding our knowledge-base, breaking down
translational barriers, improving research efficiency and with time, improving patient outcomes
Five cases and five unusual indications for autogenic renal transplantation
Five cases of renal autotransplantation representing five different indications for the procedure are presented and discussed
Arteriography during ex vivo renal perfusion A complication
A case of bilateral renal-cell carcinoma unsuccessfully treated with bench surgery is reported. The reason for failure was apparently the toxicity of the contrast media used during the ex vivo arteriographic studies. © 1973
