5 min read Guest Writer While the future legality of recreational cannabis use is hotly debated at both state and federal levels, there is a broad consensus that medical cannabis is a promising, non-toxic treatment for a variety of illnesses. Despite the fact that 33 states and the District of Columbia now permit the use of medical cannabis, and numerous bipartisan bills that would allocate federal funds to research its effect on treating PTSD in veterans, there remains significant obstacles in promoting via TV and digital ads. As government policy increasingly treats medical cannabis as a promising new treatment worth exploring, media companies continue to operate and make decisions based on misinformation that is becoming harder to justify.There is no clearer example of this than CBS’s rejection of a Super Bowl ad from Acreage Holdings that shared real life stories from people who have been treated with medical cannabis. Rather than working with Acreage Holdings to address what was deemed problematic, CBS simply dismissed the ad as inconsistent with policy. For those of us in the industry, the decision was not a surprise, but I am continually baffled by the double-standard (dare I say hypocrisy?) which is on display.Related: Here’s the Medical Cannabis Super Bowl Ad CBS Refused to RunTo be fair, this is not a CBS problem, but a media problem writ large. Cannabis ads, we now know, are forbidden on television and in traditional print outlets. Even Facebook and Google, the two largest online ad platforms, have banned cannabis companies from making ad-buys. In each instance, cannabis ads are deemed inappropriate, all while advertisements for condoms, Viagra, beer, liquor and dozens (if not hundreds) of problematic, highly-addictive prescription drugs flood our screens and televisions.Big Pharma spent $3.7 billion on TV ads in 2018, featuring nearly 200 different commercials for 70 different drugs. These ads ran hundreds of thousands of times. At the same time, Budweiser, Coors and Heineken are staples of broadcast advertising, and since 2012, even hard liquor has been allowed to advertise, albeit during evening hours. The impact is clear: a 2016 study by Rand Corp found that on average, children are exposed to three alcohol advertisements each day; we now know that Big Pharma marketing was a key driver of the opioid crisis; and, Juul relied on digital ads to purposefully target children. The notion that this is about responsibility is simply untrue.Related: Spike Jonze Directed a MedMen Commercial About Cannabis. And It’s Pretty Epic.This all begs the question: what makes medical cannabis “inconsistent” with policies that have, for years, fueled addiction and substance abuse? These marijuana misanthropes typically argue that we don’t need to normalize another substance that could attract new users. This is misleading for two reasons: first, in states that have legalized recreational cannabis, there are no increases in its use or abuse and among pre-teens and teenagers, marijuana use has remained steady and even fallen in some places; and second, the ads in question are focused on medicinal cannabis, something 85 percent of Americans support. Medicinal marijuana is non-lethal and proven effective and it should be allowed to advertise to consumers to ensure they have all options available to them. So long as you are accepting ad dollars from pharmaceutical and alcohol companies, there simply is no valid, rational argument for rejecting an ad explaining the benefits of medicinal cannabis.Not only do these ad bans deprive Americans of important innovations in health care, they further cement the existing stigma and make serious, fact-based discussions increasingly rare. Our young industry already has proven to be far more ethical than the leading sponsors of addiction mentioned above, and proactive in our efforts to market responsibly. We all have taken steps to ensure we do not market to non-users, and work tirelessly to ensure children do not see the ads. That is why some cannabis advertising companies have found alternative routes, such as advertising through geo-targeting tools like AdLink, to ensure that we promote this increasingly legal product in a safe and responsible way. If CBS and others would be willing to work with us, I am certain we will be able to develop self-regulating standards that inform consumers based on fact, not fear.Related: Baby Boomers Smoking Reefer in Record AmountsMedical cannabis has proven effective in reducing symptoms associated with cancer; it can serve as a substitute to opioids for people who suffer from chronic pain as a result of HIV/AIDS; it can improve the appetite of people undergoing chemotherapy; it is even showing promise as an alternative treatment for our veterans suffering from PTSD. The American consumer, long held hostage to the whims of Big Pharma who pump us full of drugs, deserve to know about natural alternative treatments. They deserve to know that synthetic, often times lethal, prescriptions full of side effects are not the only way to treat illnesses. They deserve to know the truth and it is time for the marijuana misanthropes to work with the cannabis community and not against us.

Former West Coast Editor Chipotle Mexican Grill says it’s cleaning up its act in the aftermath of several recent foodborne illness-related outbreaks linked to its food.Scrambling to restore consumer confidence, the fast-casual chain announced today that it is taking “aggressive actions” to roll out stricter food safety practices that it claims go above and beyond current industry norms.“We have carefully examined our operations — from the farms that produce our ingredients, to the partners that deliver them to our restaurants, to the cooking techniques used by our restaurant crews — and determined the steps necessary to make the food served at Chipotle as safe as possible,” the company said in a statement.Related: After Numerous Health Incidents, Chipotle Has a Big Perception ProblemSpecifically, some of those steps include: marinating raw chicken in re-sealable plastic bags instead of in bowls; testing chicken and steak more often; scalding several fresh produce items (including onions) in boiling water to sanitize them before being chopped; and blending cilantro into steaming hot rice to kill microbes in the herb, according to the Associated Press. Additionally, some ingredients, including cheese, will be prepped at centralized locations, then delivered to nearby restaurants. All 64 ingredients that Chipotle uses will be closely scrutinized, the company claims.”Nothing is more important to me than serving my guests food that is safe” -Chipotle founder Steve Ells https://t.co/JmP72mL631— Chipotle (@ChipotleTweets) December 16, 2015To help implement and uphold its new, more stringent food prep guidelines — and to hopefully overcome the daunting challenge of not being “the food chain most associated with vomiting and diarrhea,” as our own Raymond Hennessey so eloquently put it — Chipotle has partnered with IEH Laboratories and Consulting Group. The Lake Forest Park, Wash.-based food safety testing consultancy is tasked with improving Chipotle’s employee food safety training processes.While Chipotle publicized its sweeping protocol changes today, the Food and Drug Administration (FDA) also heralded some big news of its own — the federal agency is officially joining the growing E. coli investigation surrounding the restaurant. The FDA will assist the Centers for Disease Control and Prevention (CDC) with its ongoing probe.Related: FDA Bans Some Cilantro Imports After Finding Feces and Toilet Paper in FieldsEarlier this week, the CDC said it was looking into the latest E. coli episode connected to the 1,900-location burrito chain. This time, five people who recently ate at the restaurant, identified in Kansas, North Dakota and Oklahoma, have been infected with a rare strain of the bacteria. The incident is the latest in a string foodborne illness outbreaks traced to Chipotle in several states scattered throughout the U.S., some dating back to last summer.In a sweaty appearance on NBC’s Today Show last week, Chipotle founder and co-CEO Steve Ells said the new rules would make Chipotle a leader in food safety. “We’re putting in place practices that will not enable this to happen again,” he said, “practices that are so far above industry norms today [that] we will be the safest place to eat.”Related: At Least 80 Boston College Students Sick After Eating at Chipotle Next Article December 23, 2015 Fireside Chat | July 25: Three Surprising Ways to Build Your Brand Chipotle Kim Lachance Shandrow Add to Queue Image credit: Chipotle | Facebook 3 min read –shares Chipotle Cooks Up New, Stricter Food Safety Rules Amid E.

Reviewed by James Ives, M.Psych. (Editor)Jan 17 2019AHF urges the United Nations to follow its existing mandate for the Democratic Republic of the Congo to ensure Ebola-relief efforts can proceed without the threat of violence against healthcare workers, resources and civilians.As the second worst Ebola outbreak in history rages on in Central Sub-Saharan Africa, AIDS Healthcare Foundation (AHF) urges the United Nations Security Council to protect response efforts, healthcare workers and civilians by enforcing its existing UN Organization Stabilization Mission in the Democratic Republic of the Congo (MONUSCO) mandate to ensure the security of personnel and resources being used to fight the virus.The current outbreak has seen approximately 650 confirmed and probable cases with almost 400 deaths since Aug. 1, 2018. Widespread violence from armed militias continues to wreak havoc on the affected region, stifling contact tracing and vaccination efforts and putting healthcare workers at enormous risk. In addition to Ebola spreading to the rest of the country, the WHO states that there is a “very high” risk of the virus spreading to bordering nations Uganda, Rwanda and South Sudan.Most recently, the government used the virus as a reason to prevent over 1 million people living in the affected areas from voting in the Dec. 30 elections. This caused violent protests and attacks on Ebola treatment facilities that forced aid groups to suspend operations for days and required patients awaiting test results to be moved to alternate locations. Additionally, international workers in Uganda reported increased numbers of refugees fleeing the DRC after the elections, prompting further concerns of the virus spreading into other countries.Related StoriesMany healthcare workers often care for patients while sick, study findsSleep disorders in patients with low back pain linked to increased healthcare visits, costsVirus killing protein could be the real antiviral hero finds studyThe time has come for more to be done to end the current Ebola outbreak. AHF urges the United Nations Security Council to enforce its already-in-place resolution 2049 (2018) and the MONUSCO mandate. With 17,656 authorized troops and police, more can and should be done to ensure peace throughout Ebola-affected areas by following the mandate’s assigned tasks of “preventing, deterring and stopping all armed groups and local militias from inflicting violence on civilians as well as supporting and undertaking local mediation efforts to prevent escalation of violence.””Even though we have seen an improvement in response to this outbreak compared to five years ago when over 11,000 people lost their lives to Ebola, more must be done to protect ongoing efforts in the Congo,” said AHF Africa Regional Policy and Advocacy Manager Alice Kayongo. “Workers are already putting their lives on the line to fight the virus—they should not have to worry about external threats of violence. We implore the UN to do all in its power to stop the violence in the region before this outbreak becomes even worse.”Rampant security issues, the high risk for Ebola crossing borders and instability after recent elections underscore the need for immediate action in the DRC. AHF urges that the United Nations utilize its mandate to protect healthcare personnel, resources and civilians—the world cannot afford a repeat of the disaster that hit West Africa in 2014.

Reviewed by James Ives, M.Psych. (Editor)May 9 2019A simple innovation the size of a grain of sand means we can now analyze cells and tiny particles as if they were inside the human body. The new micro-device for fluid analysis just unveiled in Advanced Functional Materials will enable more tailored experiments in drug development and disease research.It could also transform water contamination testing and medical diagnosis in natural disaster zones, where its low cost, simple use and portability make it a practical tool almost anyone can use.How it worksMicrofluidic or ‘lab-on-a-chip’ devices are commonly used to analyze blood and other fluid samples, which are pumped through narrow channels in a transparent chip the size of a postage stamp.This new chip takes that technology one step further by adding a three-dimensional cavity along the channel – think of a narrow tunnel that suddenly opens into a domed vault – which creates a mini-vortex where particles spin around, making them easier to observe.To make this cavity, researchers inserted a liquid metal drop onto the silicon mold when making the chip.The liquid metal’s high surface tension means it holds its form during the molding process.Finally the liquid metal is removed, leaving just the channel and a spherical cavity ready to use as a mini-centrifuge, explained RMIT engineer and study co-leader Dr Khashayar Khoshmanesh.”When the fluid sample enters the spherical-shaped cavity, it spins inside the cavity,” he said.”This spinning creates a natural vortex, which just like a centrifuge machine in an analytics lab, spins the cells or other biological samples, allowing them to be studied without the need for capturing or labeling them.”The device only requires tiny samples, as little as 1 ml of water or blood, and can be used to study tiny bacterial cells measuring just 1 micron, all the way up to human cells as large as 15 microns.A platform for studying cardiovascular diseasesStudy co-leader and RMIT biologist, Dr Sara Baratchi, said the device’s soft spherical cavities could be used to mimic 3D human organs and observe how cells behave in various flow conditions or drug interactions.”The ability to tailor the size of the cavity also allows for different flow situations to be simulated – this way we can mimic the response of blood cells under disturbed flow situations, for example at branch points and curvatures of coronary and carotid arteries, which are more prone to narrowing,” she said.Related StoriesIntermittent fasting shown to improve blood glucose levelsBlood based test using AI and nanotechnology devised for chronic fatigue syndromeHealthy blood vessels could help stave off cognitive declineThis capability will be of interest to Australia’s booming biomedical industry, with medical apparatus being among our top 10 exports in 2018 and worth $3.2 billion.Baratchi said the discovery was only made possible through collaboration, with technologists from the School of Engineering and mechano-biologists in the School of Health and Biomedical Sciences joining forces in RMIT’s Mechanobiology and Microfluidics research group.”Biologists like myself have been struggling to study the impact of flow-associated forces on circulatory blood cells. Now this miniaturized device developed with our engineering colleagues does exactly that,” Baratchi said.”It’s an ingenious solution that really highlights the value of cross-disciplinary research.”But some of the most exciting applications could also be outside the lab.A cheap and portable water test that anyone can useAnother promising application is for identifying parasites and other infections in waterways, especially in developing countries.”Detection of water impurities can be a difficult task because you don’t always know exactly what you’re looking for,” Khoshmanesh said.”But with this device the impurities will be captured and orbited by the vortex without any special sample preparation, saving time and money.”Whether used for analyzing water or blood samples, the low cost and portability of the device makes it attractive for a whole range of applications.The same research group recently developed a pressure pump, made from latex balloons, to operate the device.Unlike conventional pumps, which can be as large as a shoebox and cost thousands of dollars, theirs is low cost and portable.”Simplicity is a very important parameter for our designs because that often translates to lower cost and great applicability outside the lab,” Khoshmanesh said.”Our new microfluidic device, combined with our pump and a smartphone capable of capturing high-speed images, makes a low-cost, self-sufficient and entirely portable point-of-care diagnostics device.” The team: Peter Thurgood, Sara Baratchi, Elena Pirogova, Ngan Nguyen and Khashayar Khoshmanesh.

It outlines the health system’s plans to address the identified health priorities.The 2019 CHNA also features community profiles of 27 South Side community areas-; from Oakland to Riverdale -; which provide data about demographics and social determinants of health, as well as health behaviors, outcomes and resources.”The comprehensive scope and detailed data available in the Community Health Needs Assessment makes it a valuable tool for residents and health-focused community organizations to better understand our communities’ health needs, as well as areas where advocacy, education and funding would be best dedicated,” said Sherida Morrison, who chairs the Maternal and Child Health Working Group of UChicago Medicine’s Community Advisory Council. Morrison is the founder of Demoiselle 2 Femme, NFP and the Chicago Coalition on Urban Girls.”The report also demonstrates how UChicago Medicine is addressing the health and social needs of South Side communities through research, collaboration and participatory problem-solving,” she said.UChicago Medicine worked extensively with its Community Advisory Council, along with faculty and staff, to determine the CHNA’s health priorities.To conduct the research, analysis and community outreach, UChicago Medicine partnered with the Alliance for Health Equity, a collaborative of 37 hospitals working with health departments and regional and community-based organizations to improve health equity.As part of its mission and as a federal requirement for nonprofit hospitals, UChicago Medicine and Ingalls Memorial conduct a CHNA every three years, and publish an accompanying Strategic Implementation Plan designed to addresses their communities’ top health priorities.For the Ingalls Memorial service area, which covers a population of nearly 261,000 in the south suburbs, health priorities are: preventing and managing chronic diseases (heart disease, diabetes, and asthma), increasing access to maternal services through prenatal care, and promoting cancer awareness (breast and prostate).Individual CHNAs and strategic implementation plansUChicago Medicine Hyde Park “The Community Health Needs Assessment provides powerful data and valuable insight to help UChicago Medicine ensure its programs and resources are promoting health equity by supporting the most relevant and pressing health concerns in the communities that we serve,” said Brenda Battle, RN, BSN, MBA, vice president of the Urban Health Initiative, which oversees community benefit initiatives. “Through this analysis, and with extensive community collaboration and outreach, we have developed a strategic implementation plan that seeks to not only address the most critical health concerns, but also the underlying social determinants that exacerbate them.”UChicago Medicine currently works with community partners to offer programs and resources to mitigate the health concerns associated with asthma, diabetes and trauma resiliency, which were identified as priorities in prior CHNAs. These include, for asthma, the South Side Pediatric Asthma Center; for diabetes, South Side Fit and the Diabetes Empowerment Education Program; and for trauma resiliency, the Violence Recovery Program and Rapid Cycle Violence Prevention and Recovery grant program.To address health concerns associated with social determinants of health, UChicago Medicine collaborates with the South Side Health Collaborative -; which includes 30 community health centers and community hospitals comprised within the South Side -; and offers the Medical Home and Specialty Care Connection to improve access to care; for food insecurity, Feed1st; and for unemployment, Cara Connects and other workforce programs.

(Editor)Jul 11 2019Residents on Chicago’s South Side have identified chronic diseases, the need for violence prevention and trauma resiliency, and health inequities as key health concerns that they face, according to the University of Chicago Medicine’s 2019 Community Health Needs Assessment (CHNA).These issues mirror some of the concerns found in the 2016 CHNA, which identified pediatric asthma and obesity, cancer, violence, diabetes and sexually transmitted diseases as health priorities for UChicago Medicine’s South Side service area. This service area represents 23% of Chicago’s population and includes 12 ZIP codes that span 35 community areas.For the first time, the 2019 report includes a thorough analysis of social determinants of health, which are the root causes of health inequities, including higher prevalence of chronic diseases and violence in the community. These determinants include education level, poverty, unemployment, violence and community safety, access to care, and food insecurity, which results from the lack of nutritious, reliable, and affordable food sources. According to the 2019 CHNA, 53% of the service-area population lives in poverty, almost double the state poverty level, and nearly half of the community residents are at risk for food insecurity.The CHNA is used to identify community health priorities and make decisions on where to commit resources that can most effectively improve community members’ health and wellness. Priority health areas were determined through extensive data collection and analysis, including from community resident surveys and focus groups as well as from state, county and city public health and crime data.For South Side communities, the priorities for 2019-21 are: The Community Health Needs Assessment establishes which community health concerns require UChicago Medicine’s attention and resources, and we respond accordingly with strategic programs and collaborative partnerships, including those related to asthma, diabetes, violence prevention and more.

The procedure becomes clear during multi-scale modeling, as used in the chemical industry (among others). Here, the chemistry of the material is first described at the quantum level. This information is transferred to ever coarser models that map molecules and their physical properties. “If we want to predict how good the electrolyte is or how fast the ions are diffusing in the case of a lithium-ion battery, for example, we first simulate the particles at the quantum level and see what happens to them. Then, we take that information to the next level and gain insight into the dynamics, or how the particles move at the atomic level. From here, we can then go up a scale and look at how the electrolyte behaves in the macroscopic world. This gives us precise insights into all the processes and, if necessary, we can adapt or change processes,” Hamaekers explains. In this way, not only can new materials be developed or suitable materials found for specific applications. Even processes can be reviewed and improved. By simulating the processes at the atomic or molecular level in a virtual reactor, it is possible to precisely identify the points or parameters that can be optimized.At the 2018 Hanover Trade Fair, the Fraunhofer SCAI uses vivid examples to show how the design of materials can be improved through modeling, data analysis and machine learning.

Let’s take the automotive industry: while an automobile used to consist of just a handful of materials, modern cars are assembled from thousands of different materials – and demand is increasing. Whether it’s making a car lighter, getting better fuel economy or developing electric motor batteries, every new development requires finding or developing the material that has exactly the right properties. The search for the right material has often been like a guessing game, though. The candidates have usually been selected from huge material databases and then tested. Although these databases provide insight into specific performance characteristics, they usually do not go far enough into depth to allow meaningful judgments about whether a material has exactly the desired properties. To find that out, numerous laboratory tests have to be performed. The scientists at the Fraunhofer SCAI have chosen a different approach. The requirements for the substance are broken down to the inner structure of the material: that is, down to the atomic level. A specially developed software, Tremolo-X, then calculates how the particles of the material react when subjected to certain physical effects. As a result, it can be concluded whether a material with the desired properties can be developed on the basis of these particles. Virtual predictive models and atomistic simulations”Our goal is to shorten the search for the right material. This process often takes ten to twenty years, which is not only time consuming but also costly,” says Dr. Jan Hamaekers from the Fraunhofer SCAI. “The idea is to use virtual processes to sift out the number of candidates until there are only a few left to be tested in the lab.” To do this, the requirements placed on the material first have to be defined. For example, how fast a material has to cool down or what loads it has to withstand. This is simulated in two different ways on computer by using the Fraunhofer software: virtual particles are simulated at the atomic or even at the quantum level. How do they behave? How do the particles interact with each other? The other method uses existing data and knowledge to derive prediction models that make it possible to forecast the properties of a material. “The aim is to improve, create and explore new innovative materials and molecules with effective properties in the virtual computer lab in order to recommend their structure and design prior to the actual synthesis,” Hamaekers explains.

By combining multi-scale models, data analysis and machine learning, it is possible to develop improved materials much more quickly.

A woman in England died after falling onto a reusable metal straw, which pierced her head, and the tragic accident has renewed debate over bans on plastic straws, according to news reports. The woman, 60-year-old Elena Struthers-Gardner, was carrying a glass with a 10-inch-long stainless-steel straw when she fell and the straw impaled her eye, causing fatal brain injuries, according to the Daily Echo, a British newspaper. Struthers-Gardner had scoliosis, or a sideways curvature of the spine, which made her prone to falls. Struthers-Gardner died in November, and a coroner’s report on her death was released this week, according to The New York Times. The report called her death an accident. Several U.S. cities and states have already banned plastic straws to reduce the plastic entering the environment, and a similar ban is set to take effect in England in April 2020, the Times reported. But the bans have sparked concern among people with disabilities and their advocates, who say the bans make straws unavailable for those with disabilities who rely on straws to drink, according to NPR. In addition, the rigidity of reusable metal straws may pose safety risks. “I just feel that in the hands of mobility-challenged people like Elena [Struthers-Gardner], or children, or even able-bodied people losing their footing, these [straws] are so long and very strong,” Mandy Struthers-Gardner, Elena’s wife, said in a statement, the Daily Echo reported. “Even if they don’t end a life, they can be very dangerous.” In 2016, Starbucks recalled 2.5 million stainless-steel straws due to reports of young children who experienced mouth lacerations from using the straws, according to U.S. Consumer Product Safety Commission. Brendan Allen, the assistant coroner involved in Struthers-Gardner’s case, also warned about the potential dangers of metal straws. “Clearly, great care should be taken when using these metal straws. There is no give in them at all,” Allen said. He added that in this case, the metal straw may have been particularly hazardous because it was used with a lid that prevented the straw from moving. “It seems to me these metal straws should not be used with any form of lid that holds them in place,” Allen said. “It seems the main problem here is if the lid hadn’t been in place the straw would have moved away.” In Images: The Great Pacific Garbage Patch In Photos: World’s 10 Most Polluted Places Top 10 Craziest Environmental Ideas Originally published on Live Science.
