Commentary: Why the world needs more than antibiotics to cure infections – CNA

Posted: January 22, 2020 at 4:44 am

LONDON: The world is in the midst of aglobal superbug crisis.

Antibiotic resistance has been found in numerous common bacterial infections, including tuberculosis, gonorrhoea and salmonellosis, making them difficult if not impossible to treat.

Were on the cusp of apost-antibiotic era, where there are fewer treatment options for such antibiotic-resistant strains. Given estimates that antibiotic resistance will cause10 million deaths a year by 2050, finding new methods for treating harmful infections is essential.

Strange as it might sound, viruses might be onepossible alternative to antibioticsfor treating bacterial infections. Bacteriophages (also known as phages) are viruses that infect bacteria.

Theyre estimated to be the most abundant organisms on Earth, with probably more than trillions of bacteriophages on the planet. They can survive in many environments, including deep sea trenches and the human gut.

While phages are efficient killers of bacteria, they dont infect human cells and are harmless to humans.

FIGHTING VIRUSES WITH VIRUS

Although phage therapy wasused in the 1930s, it has since become a forgotten cure in the West. Although the treatment became commonplace in the former Soviet Union, it wasnt adopted by western countries largely because of the discovery of antibiotics, which became widespread after World War II.

Bacteriophages are effective against bacteria because theyre able to attach themselves to the cell if they recognise specific molecules called receptors. This is the first step in the infection process. After attaching to the bacterial cell, the phage then injects its DNA inside the bacteria.

This causes one of two things to happen. After being injected with the phages DNA, the virus will take over the bacterial cells replication mechanism and start producing more phages.

This process is known as a lytic infection. This disintegrates the cell, allowing the newly produced viruses to leave the host cell to infect other bacterial cells.

But sometimes, the phage DNA gets incorporated into the bacterial hosts chromosome instead,becoming a prophage. It usually remains dormant but environmental factors, such as UV radiation or the presence of certain chemicals such asthose found in sunscreen, can cause the phage to wake up, start a lytic infection, take over the host cell and destroy it.

Lytic bacteriophagesare preferred for treatment because they dont integrate into the bacterial hosts chromosome.

But its not always possible to develop lytic bacteriophages that can be used against all types of bacteria. As each type of phage is only able to infect specific types of bacteria, they cant infect a bacterial cell unless the bacteriophage can find specific receptors on the bacterial cell surface.

However, engineering techniques can remove the bacteriophages ability to integrate into the hosts genome, making them useful for treatment.

Engineered phages have even successfully treated a drug-resistantMycobacterium abscessus infectionin a 15-year-old girl.

TARGETED TREATMENT

The reason bacteriophages are so effective against bacteria is because theyre only able to infect specific species. Antibiotics instead target a wide range of bacteria, including friendly bacteria not causing the infection.

But this also means that a single phage wont kill all strains of a disease-causing bacteria. And because bacteria areconstantly evolving, they can develop mechanisms that prevent phage infection. For example, if the bacterial cell has evolved and changed its surface receptors, the bacteriophage wont be able to attach itself and kill the bacteria.

As part of this evolutionary process, bacteria canrapidly become resistantto a single bacteriophage. But because there aremany types of bacteriophages, we can use a phage cocktail containing a combination of different bacteriophages totarget a broader rangeof bacterial strains within a species.

This decreases the chances a bacteria becomes resistant to all phages used in treatment. Bacteriophages can also be engineered toinfect more strainsof bacteria.

COMPLICATIONS DO EXIST

However, the presence of what are known asCRISPR systemsmight complicate the possibility of using bacteriophages in treatment. CRISPR is a bacterias natural defence system that allows it tobecome immuneto genetic material, such as phages, through infection, vaccination or the transfer of antibodies.

Bacteria may be resistant to bacteriophages if they have previously encountered similar types and developed immunity.

But bacteriophages have also developedanti-CRISPRproteins that can neutralise the host bacterias CRISPR systems.

This means a phage can still be effective, despite the presence of the bacterial CRISPR system. Not all bacteriophages have genes that neutralise anti-CRISPR proteins. But with the ability to engineer phage genomes, these could be incorporated into phages that are to be used for treatment in the future.

Although phage therapy isnt routinely used in western medicine, phage cocktails are available treatments in Russia and Georgia. Phage therapy is also acommon part of medical carein Georgia, especially in paediatric, surgical care and burns hospital settings.

Phages are used on their own or in combination with antibiotics and their use hasnt been linked to anyadverse effects.

With antibiotic-resistant infections becoming more common, bacteriophages offer the ability to treat such infections.

But forbacteriophages to become commonplacein treating bacterial infections, there needs to becontinued researchinto phage biology to better understand how they interact with bacteria.

Finding effective treatments for bacterial infections other than antibiotics is the first step in fighting further instances of antibiotic resistance.

Processed Foods Highly Correlated with Obesity, Study Finds – WholeFoods Magazine

Posted: January 22, 2020 at 4:43 am

Washington, D.C.Processed foods are highly correlated with obesity, according to research from George Washington University (GW).

GW researcher Leigh A. Frame, Ph.D., MHS, said in a press release: When comparing the U.S. diet to the diet of those who live in blue zonesareas with populations living to age 100 without chronic diseasethe differences are stark. Many of the food trends we reviewed are tied directly to a fast-paced U.S. lifestyle that contributes to the obesity epidemic we are now facing. Dr. Frame is Program Director for the Integrative Medicine Programs, Executive Director of the Office of Integrative Medicine and Health, and Assistant Professor of Clinical Research and Leadership at the GW School of Medicine and Health Sciences, and co-author of the paper.

The rising obesity epidemic in the U.S., as well as related chronic diseases, are correlated with a rise in ultra-processed food consumption, says the press release. The foods most associated with weight gain include potato chips, sugar sweetened beverages, sweets and desserts, refined grains, red meats, and processed meats. Other dietary issues include insufficient dietary fiber intake and an increase in food additives.

Dr. Frame added: Rather than solely treating the symptoms of obesity and related diseases with medication, we need to include efforts to use food as medicine. Chronic disease in later years is not predestined, but heavily influenced by lifestyle and diet. Decreasing obesity and chronic disease in the U.S. will require limiting processed foods and increasing intake of whole vegetables, legumes, nuts, fruits, and water. Health care providers must also emphasize lifestyle medicine, moving beyond a pill for an ill.

An integrated approach to healthcare | News – Grand Haven Tribune

Posted: January 22, 2020 at 4:43 am

One organization is aimed at providing an integrative approach to address a patients mind, body and spirit.

PrivaMD, 16986 Robbins Rd., Suite 180, works to bridge the gap between Eastern and Western medicines. Instead of being a sick fix, physicians work to get to the root cause of a patients problem and treat them as a whole person, said Heidi Naperala, PrivaMD CEO and founder.

Were trying to shake up healthcare a little bit, she said.

PrivaMD started in October 2018, and the Grand Haven facility opened in May 2019.

Naperala has worked in healthcare since 2005 and has consulted in the United States and Canada. Naperala said they current healthcare system is broken, filled with patients who have long waits to see a doctor and dont get answers, and physicians who are busy and unable to practice the way they want.

Naperala said they wanted to provide something different, so they met with a panel of patients and perspective clients who helped them create PrivaMD. Naperala explained its the wisdom of Eastern medicine with the benefit of Western medicine technology, and providers can choose what works best for their patient.

Its the best of both worlds, she said.

Four PrivaMD physicians see patients for primary care/family medicine, womens health, functional medicine for women, and pain management/medical acupuncture. Theyre also working to add an additional provider. Two social workers also see patients. Naperala said its a collaborative environment to address the whole patient.

Providers see patients ages 5 and older.

The providers are independent and contract with PrivaMD for practice management. Naperala said the structure allows physicians to focus on getting to know patients and getting to the root cause of issues, while also giving physicians flexibility on who they refer patients to for various services.

Instead of seeing dozens of patients each day, physicians typically see eight patients daily, Naperala said. Appointments usually range from 30 minutes to an hour to provide the physician time to get to know the patient and find the underlying cause of a problem instead of masking the issue with pharmaceuticals.

We dont just pull out a chart, Naperala said. We pull up a chair.

Wellness services are also offered through PrivaMD, and individuals who arent patients can access them. Some of the services offered include IV nutrition therapy, infrared sauna, ionic foot detox, acupuncture, diagnostic testing, health cooking classes, and massages.

While insurance is accepted, Naperala said some patients opt to forego using insurance because of coverage limitations. PrivaMD also offers membership options for clients to receive services.

U.S. Rep. Bill Huizenga, R-Zeeland, recently toured the Grand Haven facility. During the congressmans visit, staff shared their journey and experiences in the healthcare field.

Huizenga credited PrivaMD for innovatively thinking and approach to delivering healthcare.

Huizenga said that although he doesnt believe the Affordable Care Act was the right answer to address healthcare, he believes it started asking the right question about what can be done to change healthcare.

While alternative medicine isnt for everyone, Huizenga said it shouldnt be excluded.

Since opening, PrivaMD continues to see an increase in patients seeing their services. One day last week alone 18 new patients signed up, Naperala said.

In the future, Naperala said plan to grow along the Lakeshore and add additional services for patients.

For more information about PrivaMD, call 616-213-0253 or visit privamd.org.

Walton heir to form health institute – Arkansas Online

Posted: January 22, 2020 at 4:43 am

Wal-Mart heir Alice Walton announced Wednesday she's establishing a Whole Health Institute to improve health care.

The current system is "a disease care system not health care system," she told members of the Northwest Arkansas Council.

The council, a group of top business, government and education leaders in the region, held its winter meeting Tuesday at the Crystal Bridges Museum of American Art in Bentonville. Walton founded the museum.

Tracy Gaudet, formerly of the U.S. Department of Veterans Affairs, will be the Institute's new director.

In November, Walton hosted a Sages and Scientists symposium at the museum.

Deepak Chopra, best-selling author and pioneer in integrative medicine, and his foundation launched Sages and Scientists in 2010.

"Using the power of convening to address and overcome critical challenges, like well-being, is a key component of the Sages and Scientists mission," Walton said in a news release at the time.

"The symposium is a catalyst for our work to improve global well-being trends and reveal the future of integrative health, humanity and the cosmos," Chopra said in the news release.

Speakers scheduled for the gathering were Rudolph E. Tanzi, professor of neurology at Harvard Medical School; Anousheh Ansari, CEO of the XPrize Foundation; Desh Deshpande, chairman of the Sparta Group; Kat Graham, actress, singer, dancer and producer; Paul Tudor Jones, founder of Tudor Investment; and Dava Newman, Apollo program professor of astronautics at the Massachusetts Institute of Technology.

Walton, longtime businesswoman and philanthropist, is the chairwoman of the museum's board and board member of the Walton Family Foundation.

Quinn on Nutrition: Nuts that are not nuts – TribLIVE

Posted: January 22, 2020 at 4:43 am

Question: You have helped me out in the past so I thought Id get your opinion on this. On a recent show, a doctor was talking about which foods to eat and which to avoid. He said that you should be eating nuts, but dont eat cashews, as they are not a nut, but rather a seed, and contain high levels of lectin. I always thought that cashews were a tree nut just like walnuts, etc. Can you shed some light on this for me?

Answer: In this case, Im afraid my opinion would not be worth much. I needed the expertise of horticulturist, Pat Regan, who humbly describes himself as a friend who spends a lot of time pondering plant parts and identification.

Pat explains that the names we commonly use often distort the scientific terms for plant parts. Fruit and vegetable are typically considered the worst abused but nut probably comes in first place, he says.

All true nuts are seeds, but not all seeds are nuts, says Pat.

Kind of like all trees are plants but not all plants are trees?

Absolutely.

So a nut is a type of seed. Got it.

Botanically, he continues, a nut is a dry fruit with one seed and a thick hard shell. Think of acorns, hazelnuts, chestnuts or hickory nuts. On the other hand, cashews come from a fleshy fruit, not a hard shell. They are more like plums, apricots, cherries and olives.

Cashews, says the Integrative Medicine Department at UC Davis, are technically not a nut. Although they grow on trees, they are really seeds that grow from a strange-looking fruit called a cashew apple.

Incidentally, Pat continues, peanuts (a legume), walnuts, almonds and pecans are not true (botanical) nuts, either. Nor are pine nuts, pistachio nuts and Brazil nuts, and yet most would call me a nut for saying so.

As for lectins, these are proteins that occur naturally in most raw plants, including cashews. The good news is that cooking destroys the activity of these proteins one reason why cashews are always sold roasted or steamed.

The other reason is that raw cashews are enclosed in a shell that contains a resin called urushiol, the same rash-causing substance found in poison ivy. Heat inactivates urushiol another reason cashews are always sold shelled and roasted or steamed.

One last word about nuts in general, including the not true nuts. They are a good source of protein, micronutrients, healthful fats and disease-fighting antioxidants. And according to the Micronutrient Information Center at Oregon State University, consuming a variety of nuts on a regular basis is associated with a lower risk for heart disease and Type 2 diabetes.

Abstract: The advent of porous materials, in particular zeolitic nanoparticles, has opened up unprecedented putative research avenues in nanomedicine. Zeolites with intracrystal mesopores are low framework density aluminosilicates possessing a regular porous structure along with intricate channels. Their unique physiochemical as well as physiological parameters necessitate a comprehensive overview on their classifications, fabrication platforms, cellular/macromolecular interactions, and eventually their prospective biomedical applications through illustrating the challenges and opportunities in different integrative medical and pharmaceutical fields. More particularly, an update on recent advances in zeolite-accommodated drug delivery and the prevalent challenges regarding these molecular sieves is to be presented. In conclusion, strategies to accelerate the translation of these porous materials from bench to bedside along with common overlooked physiological and pharmacological factors of zeolite nanoparticles are discussed and debated. Furthermore, for zeolite nanoparticles, it is a matter of crucial importance, in terms of biosafety and nanotoxicology, to appreciate the zeolite-bio interface once the zeolite nanoparticles are exposed to the bio-macromolecules in biological media. We specifically shed light on interactions of zeolite nanoparticles with fibrinogen and amyloid beta which had been comprehensively investigated in our recent reports. Given the significance of zeolite nanoparticles interactions with serum or interstitial proteins conferring them new biological identity, the preliminary approaches for deeper understanding of administration, distribution, metabolism and excretion of zeolite nanoparticles are elucidated.

Robby Andrews Lyme Disease Recovery | Running With Lyme Disease – Runner’s World

Posted: January 22, 2020 at 4:43 am

In early June of 2018 elite middle-distance runner Robby Andrews was on fire. Was, unquestionably, at the top of his running game. The then-27-year-old had just run one of his fastest races ever: 3:36 in the 1500 meters at the Oslo Diamond League Meet in Norway, beating out 18-year-old phenom Jakob Ingebrigtsen. Which is why, for Andrewswinner of the 800-meter national outdoor title in high school, holder of a national indoor record in the 800 meters as well as the 1000 meterswhat happened two weeks later was such a shock.

June 21. The USATF Championships in Des Moines, Iowa. Andrews felt confident going into the 1500 meters, but mid-race he completely ran out of steam. He placed a disappointing fifth in his heat, not even qualifying for the finals. I dont know what happened, a confused Andrews told reporters after the race.

Kevin Morris

A few days later he came down with flu-like symptoms. For the next month he battled nasty upper respiratory and sinus infections and 102-degree fevers. Training just sucked, says the Olympian. My paces were nearly 40 seconds slower than theyd been just a few weeks before. Andrews went to his doctor, who ran tests for everything from Lupus to Lyme, but they all came back negative. I was told, There is literally nothing wrong with you, recalls Andrews. But there had to be, he knew. This could not possibly be all in his head.

Still, he had a contract with Adidas to fulfill, so Andrews traveled to Europe, where he clocked disappointing times: 3:44 in the 1500 meters at the Lignano Meeting International in Italy; 1:52 in the 800 meters in Flanders Cup Kortrijk in Belgium. For the remainder of the summer, Andrews felt constantly wiped out. Normally he would be up at 7:30 to train; now, he couldnt pry himself out of bed until 10. The few days a week he forced himself to run, hed get so dizzy and breathless hed have to quit after 20 minutes. Every afternoon, he napped for up to four hours.

He kept thinking how closely his symptoms resembled those of people he knew whod had Lyme, including his older sister Kristin (also a runner who is a 2020 Olympic hopeful) and his former roommate, Donn Cabral (a 2012 and 2016 Olympian in the 3,000-meter steeplechase), so Andrews asked to have his Lyme test re-run in September. It came back positive. The doctor wanted to prescribe antibioticsthe standard treatment for Lymeimmediately, but Andrews was worried about the side effects. Instead, he decided to take the advice of a holistic doctor who had helped his sister during her bout with Lyme in 2016.

Once a week Andrews swallowed eight drops, an hour aparta concentration of herbs such as ashwagandha, rhodiola, turmeric, licorice root, and cordycep mushroomsthat the holistic doctor said would help strengthen his immune system. He soaked his feet in a proprietary blend of herbs that he was told would draw toxins out of his body. He spent more than $1,000 on treatment. He didnt care if anyone thought he was nuts. He just wanted to feel better.

And he did, for a few months. My energy went way up. I could run three miles without having to stop, says Andrews. Then, in February, it all fell apartan almost overnight, dramatic decline in his physical and emotional health. Fatigue weighed down his body. Headaches crackled through his brain. He was sweating so much at night that he had to change the sheets. And perhaps the worst? Really depressive thoughts. It was a dark couple of months, Andrews says. If it wasnt for my girlfriend and family, I would have gone days without talking to anyone or leaving the house. He raced at the U.S. Championships at the end of February on Staten Island, in the 1000 meters. I felt bad from the first step. Something was wrong. He clocked in at 2:26dead last.

Disillusioned with the holistic protocol, Andrews finally accepted a prescription for antibiotics in March. His doctor told him to take them until his symptoms were relieved for a full month. Andrewss concerns about side effects were valid; the antibiotic gave him severe fatigue and headaches, brain fog and GI issues.

Desperate to make the 2019 world championship team, he ran the 800 meters at the Adrian Martinez Classic in April, only to come in last, again. In June he set his sights on the Princeton Qualifier. I missed my college roommates wedding for it, that is how important this race was for me, he says. Midway through the 1500-meter race, he dropped out, wheezing and depleted.

Andrews felt like he was out of options. And although he didnt know it at the time, he had entered the Lyme Wars, a fiercely contested fight about why some Lyme patients develop chronic, relapsing symptoms even after treatmentand what to do about them.

A stealth pathogen. Thats what some researchers call the corkscrew-shaped bacteriaBorrelia burgdorferithat causes Lyme disease, now one of the fastest growing infectious diseases in America. More than 300,000 new cases are diagnosed every year, according to estimates from the Centers for Disease Control and Prevention (CDC).

Black-legged ticks pick up Borrelia from the birds and small mammals they feed on, then they pass the bacteria into our blood when they feed on us, usually from May to Septemberprime months for logging miles on wooded trails and grassy park paths.

Removing a tick quickly lowers your risk for infectionit takes an estimated 36 to 48 hours for the arthropod to transmit Borrelia. But once the bacteria enters your body, it is a master of evasion. The Borrelia can spread from the skin to other tissues, which can make it more challenging to treat. Your immune system takes days to a few weeks to recognize any infection, including Lyme. Thats why the standard Lyme testwhich checks for antibodies (not the bacteria itself)can more easily give a false negative test early on, like Andrewss did.

When your body finally detects Borrelias presence, it launches an immune response to fight it, which is what can bring on flu-like symptoms such as sluggishness, fatigue, muscle aches, and joint pain. Runnersespecially those who spend hours outside during the summer training for fall marathonscan attribute symptoms to overtraining.

The majority of Lyme cases are easy to treat and cure with a 10- to 28-day course of antibiotics, says Paul Auwaerter, M.D., the president of the Infectious Diseases Society of America (IDSA). Ying Zhang, MD, Ph.D., a leading expert on the Lyme bacteria and a professor of molecular microbiology and immunology at the Johns Hopkins Bloomberg School of Public Health, disagrees. Lyme can be a really terrible disease and a very complex one. Different patients have different responses, and the disease can manifest in different ways, says Zhang, who believes Lyme can indeed develop into a chronic form that resists the current antibiotic treatment.

Indeed, for around 20 percent of Lyme patients, a dose of antibiotics isnt the end of the story. Not by a long shot. They continue to suffer from a variety of symptoms that can last for months, even years: fatigue, headaches, muscle and joint pain, difficulty concentrating, and sleep disruptions. The frequently used medical term for these persistent problems is Post-Treatment Lyme Disease Syndrome (PTLDS). PTLDS means that we know that a patient has had Lyme, has gotten a course of antibiotics, and doesnt feel like theyve bounced back, says Auwaerter.

PTLDS is often referred to as chronic Lyme, a term Auwaerter disparages as a catchphrase for otherwise unexplained fatigue, pain, and neurologic symptoms in people who dont meet the diagnostic criteria for Lymeusually obtained by medical history, a positive blood test, and physical exam. But diagnosing Lyme can be tricky. In the first three weeks after infection, the test detects Lyme only 29 to 40 percent of the time and some 30 percent of all Lyme patients, like Andrews, dont get the telltale bullseye rash.

Drew Reynolds

What really keeps the controversy alive is this: There isnt yet a sensitive and reliable test that can determine if ongoing symptoms after Lyme treatment are due to an ongoing active infection, says Brian Fallon, MD, director of the Lyme and Tick-Borne Diseases Research Center at Columbia University. Without one, some medical organizations, like the International Lyme and Associated Diseases Society (ILADS), believe chronic symptoms may be due to the persistence of the Lyme bacteria. They suggest that for some patients, the potential risks of treating with antibiotics for longer periods of time outweighs the consequences of an untreated persistent infection. Giving credence to this argument are several recent studies that found Lyme bacteria remained in animals even after they were treated with antibiotics. And in March, Zhang and his colleagues found that a slow-growing form of persister Lyme bacteria not only resisted standard single antibiotic treatment, but also caused more severe arthritis-like symptoms in mice. They found that a cocktail of three antibioticsdaptomycin, doxycycline, and ceftriaxonecompletely killed the bacteria, and they are now planning clinical trials to see if the result is the same in humans.

On the other hand, groups including the IDSA maintain that symptoms that linger after antibiotic therapy are not due to an ongoing active infection of the Lyme bacteria and therefore should not be treated with additional rounds of antibiotics because theyre unlikely to help. Six clinical trials have shown that long-term antibioticsbeyond the recommended 28 dayare not effective, says Auwaerter. Plus, long-term use of antibiotics can lead to serious side effects, such as blood clots and, even, in rare cases, death.

If chronic symptoms are not caused by an active infection, then what? It could be due to an autoimmune reaction, where a prior infection has triggered an immune reaction that is now acting independently, or it could be that the prior infection changed the brain activation patterns, Fallon says. Theres some evidence to support both of these processes.

While researchers debate, patients are left sick, with lots of questions, and no good answers. Its devastating for peoples lives and some are willing to try anything to get better, Fallon says. After his dismal race in Princeton, Andrews was one of them.

This June, after battling symptoms for nearly a year, Andrews visited Mark Sivieri, M.D., a board-certified family practice doctor in Maryland who is also board certified in integrative medicine (which pairs traditional medicine with complementary therapies). Andrewss cousin had been seeing him for her own ongoing Lyme symptoms. There was an instant connection: Sivieri had also been a professional runner; he and Andrews even shared a coach at one point. During the three-and-a-half-hour appointment, Sivieri studied Andrewss previous blood tests. He noticed that, in addition to Lyme, Andrews had tested positive for two other tick-borne infections (Andrews says the doctor who had ordered the test never mentioned them).

Ticks carry and transmit loads of other bacteria, parasites, and viruses beyond Borrelia burgdorferi. A single tick can make a person sick with several diseases at the same time, including Anaplasmosis (a bacterial infection that causes fever, aches, chills, and muscle aches), Babesiosis (a parasitic infection that attacks red blood cells), and Powassan virus (which can cause an infection in the brain and can even be deadly). And not all doctors check for these when they are focused on Lyme; those who do test for them may believe the antibiotics prescribed for Lyme will be enough to wipe out the co-infections. The estimates for co-infection rates with Lyme disease can widely range anywhere from about two to 40 percent. And not only are some, such as Powassan, more dangerous than Lyme, but simultaneous infection, some research suggests, may make Lyme harder to treat or recognize, and might affect how the immune system responds to Burgdorferi.

Sivieri put Andrews on a 60-day course of the two antibiotics hed previously been taking to kill the bacteria for Lyme; he also prescribed a medication to wipe out the co-infections. He said the night sweats and the shortness of breath, thats what the Babesia parasite does, it eats your red blood cells and prevents the oxygen from moving around your body. Thats obviously a big concern for runners. I couldnt breathe well when running, right from the start, says Andrews. And Im a trained athlete.

Sivieris tests showed that Andrews was also sensitive to gluten and dairy; he recommended avoiding them to help take pressure off his immune system. My stereotypical Italian grandma was aghast when I told her no more pasta and chicken parmesan, Andrews says. That was a big transition for me. But if thats whats was going to get me better, I didnt care at all.

Sivieri then turned to natural remedies to help strengthen Andrewss immune system, putting him on adaptogenic herbssaid to help with all types of stresssuch as curcumin which can reduce the inflammatory response caused by Lyme.

Using alternative medicine to nuke hard-to-kill bugs might sound like folklore, but science is starting to back the theory: Zhang recently found that, in laboratory dish tests, 10 oilsincluding from garlic cloves, myrrh trees, thyme leaves, allspice berries, and cumin seedsshowed strong killing activity against the non-growing and slow-growing persister forms of the Lyme bacteria, even better than standard antibiotics. We need to do proper clinical trials, to see how to use them more effectively without being toxic but [in the future, I believe that] the more effective treatment is going to come from a combined approach of antibiotics with essential oils or natural products.

The combination of traditional and alternative medicine helped Andrews. The past year has been brutal, but he finally feels like his old self again. I wake up in the morning and I have energy all day, he says. Im not sweating at night, [there are] no headaches. The depressive thoughts are gone. Im training at full capacity. He plans to run the indoor season in 2020, still in hopes of achieving the Olympic qualifying time.

He stopped taking antibiotics in mid-August, now its complementary treatmentsincluding vitamin C for his adrenals and immune system and curcumin for inflammation. He still avoids gluten and dairy and is content to continue the regimen for the near future. The supplements could be pointless, but hes not going to chance it. It seriously feels like I have my life back, he says. This is me. Im back to me.

OVR Technology Is Creating Olfactory Virtual Reality for Health Care, Education and Training – Seven Days

Posted: January 22, 2020 at 4:43 am

My first experience with olfactory virtual reality was truly trippy. Wearing a VR headset and holding a controller in each hand, I stood in a 3D room at OVR Technology in Burlington, gazing at a virtual table holding plates of tomato slices, garlic bulbs and basil leaves. As instructed by Jesse Stein, vice president of product and marketing, I used the controllers to pick up items with my white-gloved hands, bring them to my nose for a whiff and place them on the pizza beside me.

After I'd plunked down a few slices and bulbs, a lawn mower drove by, unattended, sounding just like a lawn mower and spewing grass in my general direction. As the four-wheeled interloper receded, I pushed a red button to slide the pizza into the oven.

The visual and auditory elements of this surreal experience were amazing. I felt like I'd been transported onto the Holodeck in a "Star Trek" show. But most remarkable were the scents provided by OVR Technology garlic, cut grass, hot Italian pie that wafted toward my nose at just the right moments.

The first time OVR Technology CEO Aaron Wisniewski tried VR, "It kind of blew my mind," he told Seven Days. "I immediately was like, 'This is the future. This is so cool. There is so much that can be done with this. But the thing that's missing, the thing that would make it feel like a real experience, is what I specialize in, which is scent.'"

Unbeknownst to many, "Our sense of smell is the only one of our senses with a direct link to the memory and emotions section of our brain, the limbic system," Wisniewski said in a TEDx Talk recorded in Stowe last May. "Every time you have an experience, it's inextricably linked to the smell of that moment and stored in the memory banks that make us who we are."

He believes that olfactory virtual reality could serve many purposes, from enjoyable to life changing. It could enhance a meditation practice, train employees in a task, teach first responders greater resilience to stress, diagnose anosmia (a loss or impairment of the sense of smell) and deepen exposure therapy for vets with posttraumatic stress disorder.

OVR Technology's mission, Wisniewski said in an interview, "is to have real-world positive impacts by enhancing the virtual world through scent. It's not just a cool thing or a gimmick. We want outcomes and impacts that are measurable."

The company aims to improve health care, education and training, and its first product is a three-component platform called Architecture of Scent. One component is the small ION device, which straps onto a VR headset, close to the wearer's nose. ION contains the second component, nine cartridges that store and emit highly realistic scents created by the company, or "scentware." The third component is software that interacts with VR software to cue delivery of scents in precisely measured doses timed to correspond to the headset wearer's behavior.

The scent of a rose should "be more intense the closer you get to it," Stein said. "Or, if there's a wind blowing" in the VR environment, the software calibrates "how the wind carries that scent."

Wisniewski cofounded OVR Technology in 2017 with his brother Sam Wisniewski, company COO and CFO; Matt Flego, CTO; and Erik Cooper, head of design. The four met at Generator maker space in Burlington. There, the Wisniewski brothers founded Alice & the Magician Cocktail Apothecary, which sells edible elixirs and aromatic mists; and Flego and Cooper founded M//E Design, an industrial design and prototyping company.

The Wisniewskis still own Alice & the Magician, now located on Pine Street, but spend most of their time at OVR Technology. "A really talented operations manager takes care of the day-to-day" at Alice & the Magician, Aaron Wisniewski said.

Last June, Flego and Cooper closed M//E Design, which had designed such products as the popular Core 360 active seating chair, to focus exclusively on the new business.

In 2015, the four founders learned about VR from Kip Steele, technical leader at Asure Software. Steele, who worked in information technology at the University of Vermont at the time, brought a headset to Generator.

About a year later, Champlain College started an experimental project to combine scents with VR. Faculty members invited Wisniewski to serve as a scent expert, and soon he and the other founders had created software, scentware and a prototype of the ION device.

"It looks like an elaborate mousetrap," Flego said of the prototype. At the proof of concept a successful demonstration of the olfactory virtual reality technology "we impressed some people, got a little bit of traction and a little bit of money," he recalled. Wisniewski was convinced that the product had huge potential, and soon his brother, Flego and Cooper joined him in creating OVR Technology.

A key collaborator who has helped guide development of the Architecture of Scent is Albert "Skip" Rizzo, a research professor at the University of Southern California and director for medical virtual reality at USC's Institute for Creative Technologies. He researches the use of VR to assess, treat, rehabilitate and increase resilience in psychology patients. Rizzo received the American Psychological Association's 2010 Award for Outstanding Contributions to the Treatment of Trauma for his work using virtual reality-based exposure therapy to treat PTSD.

Rizzo "has a deep understanding of how scents are an integral piece of the puzzle of PTSD," Wisniewski said. "We've been working closely with him and getting feedback from him on what types of scents to develop and how our technology can be effective with exposure therapy."

Rizzo is currently perfecting his Bravemind VR program for vets with PTSD and plans to distribute it to more than 100 VA hospitals around the country. OVR Technology is developing combat-related scents to enhance Bravemind.

Closer to home, OVR Technology is collaborating with David Lg Tomasi, who teaches and conducts research in the UVM Integrative Health program and Larner College of Medicine. He's also a clinical psychologist and psychotherapist at the UVM Medical Center.

"There is a lot of neuroscientific evidence of the role that sensory activation plays in our brain for general well-being," Tomasi said, "and by that I mean either in the stimulation of the olfactory bulb or the virtual-reality type of strategy."

Just as people can trick their brains into stimulating salivation by thinking about sucking on a lemon, he explained, VR can trick the brain into releasing neurotransmitters that are specifically focused on well-being.

"What is brand new is this combination" of olfactory stimulation and virtual reality, Tomasi emphasized.

"We've been doing integrative medicine for years on the patient psychiatry unit, mostly focusing on dietary examples, exercise, meditation, art therapy," he continued. But some patients can't participate due to medical issues, and Tomasi believes OVR Technology's product could help reduce their pain, stress and anxiety.

Not all olfactory virtual reality scenarios are as wacky or surreal as the pizza-with-lawn-mower demo I experienced. Tomasi found OVR Technology's woods-like demo so realistic that it was "really peaceful and nurturing. You could walk around, see the trees, see the landscape, the leaves and stones and rocks. You could pick up a marshmallow to roast, and you could have some water."

Sometimes, users forget that they're not in the real world. "Early on, we had a demo with a picnic table in it," Wisniewski recalled. "People would become so immersed in the environment that, within a minute or two, they would try to lean on the picnic table and fall over." After seeing a couple of people "hit the deck," the company adjusted the demo to keep people safe.

Within the next month or so, Tomasi and OVR Technology will launch a pilot study to collect qualitative and quantitative data from 12 volunteer UVM Medical Center inpatient subjects on the therapeutic value of olfactory virtual reality. A lot of research went into the study, which the team is confident is the first of its kind worldwide in a psychiatric setting. "It is groundbreaking research," Tomasi enthused.

A few other companies are also developing olfactory virtual reality, but OVR Technology's current challenges stem from more immediate concerns than competition. Because the VR industry is evolving quickly toward faster and smaller headsets, the company is already designing a smaller version of the ION device. It's also creating a "volume knob" to allow users to control the strength of scents delivered by the device.

Truth be told, I had a hard time smelling the tomato, basil and grass clippings in the demonstration. Though my brother's nose made him a successful New York City sommelier, my sniffer thinks Bayley Hazen Blue is a lot like Brie left in the fridge too long. I'd have welcomed a way to control the scent intensity, as would others who've experienced OVR Technology demos, Flego said.

"It's a lot like hearing: Different people hear different frequencies, and there are tons of factors that degrade over time," Stein noted.

But the company is determined to make its technology seamless. In the long term, "we envision that the relationship between smell and virtual reality will become as ubiquitous as sound and television," Wisniewski said.

His commitment to this goal stems in part from a cautionary concern. Culturally, we have deprioritized our sense of smell and sanitized our environment to include fewer scents, Wisniewski noted. He cited research showing that anosmia can lead to depression, anxiety and physical harm.

"If we continue down the path of being glued to screens and virtual reality, while ignoring this extremely important primal sense that has been refined over millions of years, the implications are kind of alarming," he said. "We don't have that many senses. You take away one, and I don't see it going well."
