LITFL Review 315

LITFL • Life in the Fast Lane Medical Blog LITFL • Life in the Fast Lane Medical Blog - Emergency medicine and critical care medical education blog Welcome to the 315th LITFL Review! Your regular and reliable source for the highest highlights, sneakiest sneak peeks and loudest shout-outs from the webbed world of emergency medicine and critical care. Each week the LITFL team casts the spotlight on the blogosphere’s best and brightest and deliver a bite-sized chunk of FOAM. The Most Fair Dinkum Ripper Beauts of the Week Rob Macsweeney of Critical Care Reviews posts the 2 hour livestream of the ADRENAL Trial as FOAM. Fast forward to 1:01:31 to see the beginning of the presentation and save an hour of your time.  This international RCT of 3800 patients in septic shock showed no difference in 90 day mortality, but an improved shock reversal, LOS in the ICU, blood transfusion requirements, and shorter time needed for mechanical ventilation in those given hydrocortisone vs placebo. We still don’t have long term outcomes, however the authors are planning on publishing 6 month outcomes at a later date. See too other notable FOAM on the same study,:EM Lit of Note, EM Crit, and The Bottom Line also analyze the recent ADRENAL trial results. [SR]  Also from Rob Mac Sweeney and the Critical Care Reviews team comes the CCR Book 2018–all the best critical care trials of 2018 distilled and discussed for easy reading. Absolutely essential #foamed. ...

The objective of this work was to introduce high-intensity ultrasound (HIU) in different positions within a scraped surface heat exchanger (SSHE) and evaluate the crystallization behavior and physical properties of a low saturated, soybean-based fat. The SSHE in this study was composed of one pump (flow rate of 11 L/h), two crystallization barrels (32 °C, 344 rpm), and one pin worker (208 rpm). HIU was placed before the first crystallization step, or barrel 1 (HIU-0), between the two barrels (HIU-1), between barrels 2 and the pin worker (HIU-2) and after complete crystallization in the SSHE (HIU-3). HIU amplitu...

Sánchez-Burgos, Libier Meza-Espinoza, Alejandro Pérez-Larios, J. Emanuel Bojorquez-Quintal, Efigenia Montalvo-GonzálezAbstractThe combined effect of vacuum, heat and ultrasound (vacuum-thermosonication, VTS) on soursop puree was investigated with regard to the viability of Escherichia coli and Staphylococcus aureus, inactivation of polyphenol oxidase and sensory quality. The VTS conditions were: vacuum (8.46, 11 and 16.9...

In this study, freshwater and marine migrations of the endangered salmonid North Sea houting (Coregonus oxyrinchus (Linnaeus, 1758)) were investigated using telemetry. Furthermore, physiological samples were collected from North Sea houting and from resident and anadromous populations of the closely related European whitefish (Coregonus lavaretus (Linnaeus, 1758)) to compare hypo-osmotic tolerances. On average, North Sea houting spent 193 days at sea where the mortality was 36%. Most fish returned from sea in the autumn, and river entry correlated inversely with river temperature and positively with discharge. Fish spent a...

Canadian Journal of Zoology, e-First Articles. Recent studies have noted the differential effects of marine versus terrestrial diets on the carbon and nitrogen stable isotope (13C and 15N, respectively) diet-to-tissue discrimination values and incorporation rates for omnivorous and carnivorous mammals. Inaccurate estimates of these parameters may result in misrepresentation of diet composition or in the timing of diet shifts. Here, we present the results of a diet-switch experiment designed to estimate diet-to-tissue discrimination values and incorporation rates for tissues of gray wolves (Canis lupus Linnaeus, 1758) fed a...

Publication date: Available online 18 November 2019Source: Sensors and Actuators A: PhysicalAuthor(s): Wang Luo, Haobin Dong, Jianmei Xu, Jian Ge, Huan Liu, Cheng ZhangAbstractMarine electromagnetic (EM) methods can be used for marine geophysical exploration. We proposed an all-solid-state porous Ag/AgCl electrode with high stability and a long service life as a marine electric field sensor with the ability to withstand deep sea high pressures while improving the accuracy of electric field measurements for long-period marine EM method engineering projects. Compared with a plate electrode, the all-solid-state porous electro...

Rodriguez-PáezAbstractThough there may not be consensus regarding the toxicity of glyphosate, given the strong interest in its removal from water sources nanotechnology was used in this work to that end. Nanoparticles of zinc oxide (ZnO-NPs) were synthesized in a controlled manner by chemical route. The ZnO powders were then characterized by infrared and UV–Vis absorption spectroscopies, X-ray diffraction and scanning electron micros...

Authors: Membrey B, Miranda S, Lévesque H, Cailleux N, Benhamou Y, Armengol G Abstract Giant cell arteritis is the most common primary vasculitis of large-vessel occurring in subjects over 50 years of age. Many imaging techniques has been evaluated to improve the diagnosis of giant cell arteritis. Among these imaging techniques, ultrasound has shown good performances to detect inflammatory involvement of the temporal arteries as well as branches of the aorta. Several publications and recent EULAR recommendations have emhasized the place of this tool in the diagnosis of giant cell arteritis. PMID: 31...

This study presents the relationship between inputs of elements (especially biominerals), their recycling mechanisms and the average residence time of the major elements in mull humus.In forest ecosystems with generally low element inputs, decomposing leaf litter is an important source of soil nutrients. While the processes and the release speeds of elements, such as C, N and P, are well determined during litter degradation, less is known about elements like Fe, Al, Mg, Mn, Si, Ca, K, or Na, some of which are essential for tree nutrition.The objective of this study was to determine the average residence time of these eleme...
