The race begins at Charity and the cyclists will proceed to Supenaam before returning to the point of origin for the finish.Meanwhile, riders are expected to meet at National Cycling Coach, Hassan Mohamed’s Office at the National Sports Commission (NSC) on Homestretch Avenue at 8:00hrs on Saturday morning for departure to the Parika Ferry Stelling to cross over to Supenaam.Last year’s winner in the Juniors category was Curtis Dey, however this year will see a new winner being crowned.In the Veteran-45 race, Stephen Fernandes rode in first last year, while Leer Nunes came in second and Steve Ramsuchit third. The Over-45 category race was won by Andrew Spencer.The following categories will be contested this year:SeniorsJuniorsVets U-45Vets O-45NovicesMountain Bikeslast_img read more

first_imgNASHVILLE, TN (WLAF) – Wednesday morning’s state conference call was with Gov. Bill Lee and the Unified Command Group assigned to the Coronavirus pandemic.  The call also included the Commissioners of Finance, TEMA, Dept. of Health, National Guard and others.“The governor assured the legislators they are working on this 24/7 and getting all the information and data available throughout the nation and state. They are in the process of procurement of PPEs (personal protective equipment) for medical workers.  The governor stated that these are going to be very difficult times and hard choices to be made over the next few weeks,” said State Rep. Dennis Powers.Lee said he wanted to protect the liberties of individuals, but called on them to be responsible during this time. The goal is to slow the spread rapidly and deal with the after effects in a timely manner. He also wants to increase testing and stated that we are one of the top in the nation in testing and leading the South in that area, according to Powers.“The governor also wants to increase the capacity in three areas.  The first is supplies throughout the entire state, the second is personnel by postponing some medical procedures and acquiring furlough personnel and thirdly, obtaining alternate sites such as convention centers, hotels, etc. if needed for bed space.  He said we need to be prepared for increased need if it arises over the next few weeks based on models from across the country,” Powers said,“Over 27,000 tests had been performed and the current case count is over 2,200 positive with 23 deaths in Tennessee.  Every county health department in all 95 counties now has the ability to test.  The National Guard also has 35 rural test sites set up in the areas where they are needed most,” Dr. Lisa Piercy, commissioner of health, said.“We are staying ahead of the curve and all procurement issues are being handled through the local EMA director. They are also procuring additional hospital beds, ventilators, etc. based on models they are receiving, but those are changing hourly and daily and most models appear that the needs are going to increase,” Piercy said.Those on the call were also told the the guard has deployed 250 guardsmen and were going to increase that to 400, but were not taking any civilian medical workers out of the field.TEMA’s representative said, “We are working with local EMA’s using the systems to share info and data.  We are working to get ready for when the curve peaks, and we are also procuring medical equipment to be prepared.”The governor then answered questions the legislators had submitted,“What is the penalty, if any, for not adhering to the Executive Orders,” Powers said he asked.“There has not been a huge amount of enforcement, but any should be reported to local law enforcement,” Lee said in response.“Unemployment claims have gone from 2,000 a week to 70,000 a week, and the system has been overwhelmed with requests.  They are ramping up the efforts to handle all of these as fast as possible,” according  to Lee.“Supplies have already been shipped to all 95 counties, and they are being processed through the local EMA’s. Personal products are being horded by individuals, and that businesses are limiting amounts, but the hording is causing problems in the supply chains, said Lee.Ventilators have been supplied to all outpatient surgery centers, according to the governor.  He said, “We hope to get the rapid test kits in the next few days, but there is no guarantee on the shipment dates to the states.  The model from Vanderbilt will be here soon, but all the models we are looking at now show that there will be a surge in the next two to four weeks and we are procuring the beds and capacity to meet that crisis,” said Lee.“With regard to the stimulus bill, we know that small businesses are hurt the most, and I am going to get us the information on how it will be distributed to our state soon through, DHS, ECD and Workforce Development in the next few days.  It appears now that Tennessee will receive approximately $2.5 billion.  We are not sure of the timing on these funds, but more information will be coming soon,”  Lee said.    (WLAF NEWS PUBLISHED – 04/01/2020-NOON) Share this:FacebookTwitterlast_img read more

first_imgThe HIV prevalence among women in the 30 to 34 age group showed an increase, from 39.6 percent in 2007 and 40.4 percent in 2008 to 41.5 percent in 2009. The department will observe this age group closely to assess what impact ARV treatment has. 12 November 2010 As in previous years, KwaZulu-Natal had the highest HIV prevalence, followed by Mpumalanga and Free State, with overall prevalence greater than 30 percent. The North West, Limpopo, Gauteng and Eastern Cape had prevalences of between 20 percent and 30 percent. The survey, released in Pretoria this week, shows that South Africa’s HIV prevalence has remained constant at around 29 percent over the past four years. Motsoaledi noted that KwaZulu-Natal, Limpopo and the Eastern Cape had the same socio-economic conditions when it came to HIV. “This is the most important group to provide evidence when monitoring new HIV infections,” Motsoaledi said. He added that it remained to be seen how far South Africa was from achieving the Millennium Development Goal (MDG) in this age group – the MDG target for 2015 is a reduction by 25 percent, to an HIV prevalence rate of 17.3 percent. Motsoaledi acknowledged that while he was satisfied that the government had done everything possible with regards to HIV/Aids intervention on paper, he was concerned as to whether it was being implemented on the ground. Socio-economic factors “We are reviewing this,” he said. The report, presented by Motsoaledi on Thursday, showed that HIV prevalence remained constant among 15- to 24-year-old pregnant women, with 21.7 percent in 2009. This was the same as the figure in 2008, which was a decline of 0.4 percent from 22.1 percent in 2007. The Northern Cape and Western Cape were the only provinces that had HIV prevalence rates below 20 percent. While South Africa’s latest antenatal prevalence survey shows a stabilisation in the country’s HIV prevalence rate since 2006, Health Minister Aaron Motsoaledi wants more to be done to implement the government’s plans to combat the epidemic. The 2009 National Antenatal Sentinel HIV and Syphilis Prevalence survey was conducted in all nine provinces and 52 health districts, where 337 841 pregnant women booking into 1 457 public antenatal clinics for the first time were sampled during October.

first_img To make predictions, the researchers used two types of data. First, as RoboBEER poured, it measured 15 beer attributes including bubble size, beer color, gas release, and foam height and stability. Second, people’s faces were videotaped as they watched the beer videos. Artificial intelligence (AI) analyzed the videos to measure biometric factors such as pupil dilation, heart rate, and emotional expression. For each viewer, the researchers fed 28 pieces of RoboBEER and biometric data into a neural network—another AI algorithm—to see whether the data correlated with the person’s conscious ratings.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)The neural network could predict whether someone liked a beer’s foam height with about 80% accuracy, the team reports in Food Control.

And it doesn’t need a designated driver. iStock.com/doug4537 By Matthew HutsonMay. 30, 2018 , 9:45 AM As we pawn more and more jobs off on robots, there are a few you’d think we’d keep for ourselves, like beer taster. But brewers often need an automated way to ensure product quality, and a research team in Australia has developed a cheap method to help them. Their latest study assesses a freshly poured beer’s frothy top. Why focus on the bubbles? Because foam affects people’s enjoyment of beer and sparkling wine even more than taste and aroma do.To gauge people’s reactions to beer foam, the researchers needed a consistent way to produce the foam, so they employed RoboBEER, a robot they’d previously built out of Lego pieces that pours beer from bottles into a glass. They showed videos of these robo-pours to people and asked them several questions about how they liked the height and stability of the foam, as well as the beer’s clarity and overall perceived quality. The goal was to be able to show people a video and predict these ratings without a long—or any—questionnaire, and without having to serve any actual beer, which slows the evaluation process even more.

Reviewed by James Ives, M.Psych. (Editor)Dec 14 2018If you experience an injury at work, the amount of compensation you receive depends on which impairment rating system is used, according to research from McMaster University and the Netherlands.The American Medical Association (AMA) Guides to the Evaluation of Permanent Impairment is used in workers’ compensation systems, federal systems, automobile accidents and personal injury cases to rate impairment.However, a comparison of a group of injured workers assessed using the two most recent editions of the AMA guides revealed that usage of the sixth edition resulted in significantly lower impairment ratings than the fifth edition.The findings were published today in the Journal of Occupational and Environmental Medicine.”Our study shows your impairment rating will depend on the version of the AMA guides that you are assessed with,” said Jason Busse, first author and an associate professor of anesthesia at McMaster.”The difference in impairment rating is likely due to the fact that when these guides first came out, they were focused on pain and range of motion, and they have increasingly moved to more direct measures of function.Related StoriesAre Chronic Pain Relief Drugs for Children Effective?AMSBIO offers new, best-in-class CAR-T cell range for research and immunotherapyResearch sheds light on sun-induced DNA damage and repair”For example, in an earlier guide they may have measured whether a person could lift their arm above their head without discomfort, but now they look at whether the person could put a box on a shelf.”Researchers used data from a consecutive sample of 249 injured workers referred for an independent evaluation at the Orthopedisch Expertise Centrum Amsterdam between 2011 and 2012.The results showed the median whole person impairment rating was seven per cent for 131 claimants assessed with the fifth edition of the AMA guides, and four per cent for 118 claimants assessed with the sixth edition.”Because all assessors in the Netherlands switched from the fifth to the sixth edition at the same time, we were able to study two large cohorts of patients with similar injuries and explore the impact on impairment ratings,” said Busse, who is also a researcher with the Michael G. DeGroote Institute for Pain Research and Care.The other major finding of the study was considerable inconsistency of AMA Guides editions used by workers’ compensation boards across North America.”There was a tremendous variability in the edition that North American compensation boards are using,” Busse said. “The most recent version, which was the sixth, was published in 2007. Yet, for example, we have the largest compensation board in Canada, which is in Ontario, using the third revised version which came out in 1991.”Busse said he recommends consistency across compensation boards.”Workers’ compensation boards should standardize impairment rating systems so that everyone is gauged on the same scale,” he said. “If we believe that more recent editions of the AMA guides do a better job of quantifying impairment, why is it that so many Boards are using earlier versions?”Source: https://www.mcmaster.ca/ read more

first_imgReviewed by James Ives, M.Psych. (Editor)Jan 25 2019A team of Vanderbilt University Medical Center researchers, working with the U.S. Department of Veteran’s Affairs (VA), has discovered genetic associations with blood pressure that could guide future treatments for patients with hypertension.The study, an international effort using data from sources including the VA Million Veteran Program (MVP) and United Kingdom (UK) Biobank, is published in the January issue of Nature Genetics.MVP is a national effort by the U.S. Department of Veterans Affairs (VA) to collect blood samples and health information from one million veteran volunteers.Researchers discovered over 250 new genetic variants, and also identified over 400 new genes associated with blood pressure through changes in gene expression. The findings also suggest that several existing drugs not currently used to treat high blood pressure could be used to potentially lower blood pressure.”We’re redrawing the map of blood pressure genetics,” said Todd Edwards, PhD, associate professor of Medicine in the Vanderbilt University School of Medicine and one of two senior corresponding authors with Adriana Hung, MD, MPH.Related StoriesPoor sleep associated with high blood pressureHealthy blood vessels could help stave off cognitive declineNew ACC/AHA guidelines could improve detection of gestational hypertensionWhile large swaths of the map remain to be filled in, the researchers said they are closer than ever to being able to improve the treatment of high blood pressure based on the patient’s genetic make-up.”The door is wide open,” said Vanderbilt research fellow Jacob Keaton, PhD, whose identification of gene-drug interactions was a key part of the study. “We’re bringing findings to the table that we can do something with to have an impact on precision medicine.”The study analyzed the relationship between genetic variants and blood pressure traits utilizing the electronic health records of more than 300,000 MVP participants and more than 140,000 UK Biobank study participants.Thirty percent of the MVP participants were African-Americans, Hispanics, Asians and Native Americans — making it one of the most racially diverse genetic inquiries of its kind, said Hung, associate professor of Medicine in the Division of Nephrology and Hypertension. Researchers replicated their findings by analyzing 17,000 samples from the Vanderbilt University biobank, BioVU, and 300,000 from large genetic consortia of blood pressure studies.”Blood pressure is incredibly complicated,” Edwards said. “It may be that as we increase the sample size of these kinds of studies … we’ll discover that no place in the genome has a zero effect on a trait like blood pressure. It’s just that some of the effects are incredibly subtle.”Much more needs to be learned.Currently “we can’t accurately say what your blood pressure’s going to be at age 65 by looking at your genotype,” Edwards said, “but we might be able to tailor your treatment a little more accurately with some of the results we have from this study.”Source: https://ww2.mc.vanderbilt.edu/last_img read more

first_imgTen ophthalmologists (four general ophthalmologists, one trained outside the US, four retina specialists, and one retina specialist in training) were asked to read each image once under one of three conditions: unassisted, grades only, and grades + heatmap.Both types of assistance improved physicians’ diagnostic accuracy. It also improved their confidence in the diagnosis. But the degree of improvement depended on the physician’s level of expertise.Without assistance, general ophthalmologists are significantly less accurate than the algorithm, while retina specialists are not significantly more accurate than the algorithm. With assistance, general ophthalmologists match but do not exceed the model’s accuracy, while retina specialists start to exceed the model’s performance.”What we found is that AI can do more than simply automate eye screening, it can assist physicians in more accurately diagnosing diabetic retinopathy,” said lead researcher, Rory Sayres, PhD.. “AI and physicians working together can be more accurate than either alone.”Like medical technologies that preceded it, Sayres said that AI is another tool that will make the knowledge, skill, and judgment of physicians even more central to quality care.”There’s an analogy in driving,” Sayres explained. “There are self-driving vehicles, and there are tools to help drivers, like Android Auto. The first is automation, the second is augmentation. The findings of our study indicate that there may be space for augmentation in classifying medical images like retinal fundus images. When the combination of clinician and assistant outperforms either alone, this provides an argument for up-leveling clinicians with intelligent tools.” Source:https://www.aao.org/newsroom/news-releases/detail/how-ai-can-make-ophthalmologists-more-effective Reviewed by James Ives, M.Psych. (Editor)Mar 19 2019As artificial intelligence continues to evolve, diagnosing disease faster and potentially with greater accuracy than physicians, some have suggested that technology may soon replace tasks that physicians currently perform. But a new study from the Google AI research group shows that physicians and algorithms working together are more effective than either alone. It’s one of the first studies to examine how AI can improve physicians’ diagnostic accuracy. The new research will be published in the April edition of Ophthalmology, the journal of the American Academy of Ophthalmology.This study expands on previous work from Google AI showing that its algorithm works roughly as well as human experts in screening patients for a common diabetic eye disease called diabetic retinopathy. For their latest study, the researchers wanted to see if their algorithm could do more than simply diagnose disease. They wanted to create a new computer-assisted system that could “explain” the algorithm’s diagnosis. They found that this system not only improved the ophthalmologists’ diagnostic accuracy, but it also improved algorithm’s accuracy.More than 29 million Americans have diabetes, and are at risk for diabetic retinopathy, a potentially blinding eye disease. People typically don’t notice changes in their vision in the disease’s early stages. But as it progresses, diabetic retinopathy usually causes vision loss that in many cases cannot be reversed. That’s why it’s so important that people with diabetes have yearly screenings.Unfortunately, the accuracy of screenings can vary significantly. One study found a 49 percent error rate among internists, diabetologists, and medical residents.Recent advances in AI promise to improve access to diabetic retinopathy screening and to improve its accuracy. But it’s less clear how AI will work in the physician’s office or other clinical settings. Previous attempts to use computer-assisted diagnosis shows that some screeners rely on the machine too much, which leads to repeating the machine’s errors, or under-rely on it and ignore accurate predictions. Researchers at Google AI believe some of these pitfalls may be avoided if the computer can “explain” its predictions.Related StoriesAXT enhances cellular research product portfolio with solutions from StemBioSysScientists develop universal FACS-based approach to heterogenous cell sorting, propelling organoid researchAMSBIO offers new, best-in-class CAR-T cell range for research and immunotherapyTo test this theory, the researchers developed two types of assistance to help physicians read the algorithm’s predictions.center_img Grades: A set of five scores that represent the strength of evidence for the algorithm’s prediction.
