Using a specialized algorithm along with the app, medical practitioners can calculate left ventricular ejection fraction (LVEF), which is one key measure of heart health, upon which physicians base diagnostic and therapeutic decisions.LVEF measure how much blood is being pumped out of the left ventricle of the heart with each contraction and is expressed in a percentage. A normal LVEF ranges from 55 to 70 percent. An LVEF of less than 40 percent may confirm a diagnosis of heart failure. An LVEF of less than 35 percent increases the risk of an arrhythmia that can cause sudden cardiac arrest or death.To test device accuracy, researchers at the Childhood Cancer Survivorship Clinic (CCSC) at City of Hope conducted a cross-sectional study. It compared LVEF using the Vivio wireless device, two-dimensional (2D) echocardiography, and gold-standard cardiac magnetic resonance (CMR) imaging in childhood cancer survivors exposed to anthracycline, who risk potential cardiac dysfunction from the exposure, which can often develop at a time when they are least engaged in long-term survivorship care, a report in HospiMedica said.In all, 191 consecutive cancer survivors participated in the study, with a median anthracycline dose of 225 mg/m² (milligrams per square meter). The researchers found that echocardiography overestimated mean LVEF by 4.9 percent compared with CMR. However, no difference was seen between mean LVEF readings from Vivio and CMR.Also, when compared with CMR, the detection of cardiac dysfunction via echocardiography was weak, but Vivio-based measurements had considerably better sensitivity. The study was published on June 21 in Clinical Cancer Research.Last year, Caltech researchers worked with medical practitioners to test the app on 72 volunteers between 20-92 years old at an MRI facility. Using Vivio, doctors simply held iPhones against the volunteers’ necks for one to two minutes. Afterward, the volunteers immediately received an MRI examination, and data from both tests were compared. The measurements made by Vivio had an error of ±9.9 percent compared that of an MRI. In comparison, the error for echocardiography was roughly ±10.2 percent.“In a surprisingly short period, we were able to move from invention to the collection of validating clinical data,” said Caltech’s Dr. Mory Gharib after the trials.Gharib, Hans W. Liepmann Professor of Aeronautics and Bioinspired Engineering and head of the Gharib Research Group at Caltech, is the senior author of a separate on the study that was published in the July 2017 issue of Critical Care Medicine.“What is exciting about this study is that it shows our technique is as accurate as echocardiography at estimating LVEF when both are compared to the gold standard of cardiac MRI,” he said. “This has the potential to revolutionize how doctors and patients can screen for and monitor heart disease both in the U.S. and the developing world.” Pasadena Will Allow Vaccinated People to Go Without Masks in Most Settings Starting on Tuesday Top of the News Community News Make a comment More Cool Stuff Name (required)  Mail (required) (not be published)  Website  Pasadena’s ‘626 Day’ Aims to Celebrate City, Boost Local Economy Subscribe 4 recommendedShareShareTweetSharePin it center_img Community News faithfernandez More » ShareTweetShare on Google+Pin on PinterestSend with WhatsApp,Virtual Schools PasadenaHomes Solve Community/Gov/Pub SafetyCitizen Service CenterPASADENA EVENTS & ACTIVITIES CALENDARClick here for Movie Showtimes Science and Technology Caltech Smartphone App Helps Identifies Heart Problems in Childhood Cancer Survivors From CALTECH Published on Monday, July 9, 2018 | 4:23 pm First Heatwave Expected Next Week Business News Get our daily Pasadena newspaper in your email box.

Council hits back after being revealed as slowest for conveyancing searches in the UK

first_imgA local council has hit back after research by TV presenter Phil Spencer’s property data company MoveIQ identified it as the slowest in the UK to complete conveyancing searches.Using Freedom of Information requests, MoveIQ found that Stratford District Council can take 95 days to carry out searches and that 15% of councils are failing to meet a government target to complete searches within 10 days.A spokesman for the council has released a statement to say that although concern had been raised about the performance of its  service, he said 95 days was the “oldest outstanding search” at that time.“This has given the erroneous impression that Stratford District Council is unaware of or does not care about providing a good service,” says Councillor Daren Pemberton (left).“Nothing could be further from the truth and this is not where we want to be as an authority.“Earlier this year I announced an investment of £315,000 in a new IT system for the service, which has also had an additional staff member recruited.“The current antiquated paper-based system is unable to meet the demands now placed upon it. That project has been under way for some months and the new system goes live later this year.”Conveyancing searchesOther councils identified by MoveIQ for not meeting the 10-day standard for conveyancing searches include Wyre Forest, Rochford, Herefordshire and Epping Forest. The most expensive councils are Hammersmith & Fulham at £333.50; Brent (£320); Croydon (£305); Kingston upon Thames (£303.50p) and Kensington & Chelsea (£303.50).“The Prime Minister has pledged to fix what she herself describes as Britain’s ‘broken’ housing market, yet our research reveals that councils across the country are adding needless delays and expense to the home buying process,” says Phil Spencer (right).Phil Spencer Herefordshire MoveIQ Rochford Stratford District Council Stratford-upon-Avon Daren Pemberton Epping Forest Wyre Forest November 8, 2018Nigel LewisWhat’s your opinion?

Deloitte: About 30% of U.S. shale operators are ‘technically insolvent’

first_imgDeloitte: About 30% of U.S. shale operators are ‘technically insolvent’ FacebookTwitterLinkedInEmailPrint分享E&E News ($):After over a decade of growth, U.S. shale drillers have entered a period of “great compression” and extreme volatility that could last years as demand for oil has plummeted during the coronavirus pandemic, according to a new report from consulting and accounting firm Deloitte.Nearly one-third of U.S. shale operators are “technically insolvent” at current oil prices and may seek to be acquired or declare bankruptcy, Deloitte said in its analysis. The contraction could have a “domino effect” on the global oil and gas industry given the outsize role of U.S. shale production, said the report, which was released yesterday.Before COVID-19 hit, oil demand worldwide was already trending downward and the market had shown some instability, mostly due to concerns over climate change, said Duane Dickson, U.S. oil, gas and chemicals leader and a vice chairman at Deloitte. The global pandemic appears to have accelerated an energy transition away from the fossil fuel, he said.With the coronavirus upending global supply chains and forcing many industries into telecommuting, oil demand is not expected to return to pre-pandemic levels “anytime soon,” according to Deloitte’s report. It is unclear when people will resume driving, using ride-share services and flying as much as they did pre-pandemic, said Dickson, co-author of the report.“We see at least three to five years before a recovery of all the major markets occurs,” he said.With Deloitte estimating that about 30% of U.S. shale operators can’t break even when shale prices dip below $35 a barrel, some firms could declare bankruptcy in the next few years, Dickson said. Others could turn to consolidation.[Miranda Wilson]More ($): Pandemic drives U.S. shale into ‘great compression’ — reportlast_img read more
