The National Heart, Lung and Blood Institute has awarded an Oklahoma Medical Research Foundation scientist $5.9 million to study new ways to control bleeding like that which occurs in aneurysms.
OMRF researcher Courtney Griffin, Ph.D., received a seven-year grant to pursue novel research into blood vessel function and factors that lead to uncontrolled bleeding.
“Seven years is like paradise to a scientist. It allows us to address questions and take our research in new directions we couldn’t have before,” said Griffin, who joined OMRF from the University of North Carolina at Chapel Hill in 2008. “This will give us the opportunity to dig in on basic science questions that could lead to new drugs and therapies for devastating conditions.”
The grant was awarded under a new federal granting program known as the R35, which was established to promote scientific productivity and innovation by providing sustained support and increased flexibility in research. NHLBI program officer Yunling Gao, Ph.D., said the R35 award is designed to provide long-term support to outstanding investigators like Griffin who are conducting research that breaks new ground or extends ongoing studies that are making significant contributions to the field.
“Dr. Griffin has been supported by the NHLBI’s programs over the past decade, and she has emerged as an expert in the field on protease-mediated regulation of vascular stability,” said Gao. “We look forward to her new breakthroughs and achievements for years to come.”
Griffin’s work is focused on proteases—proteins that chew up other proteins. At OMRF, she studies the role proteases play in a healthy setting and also the damage they can cause in blood vessel development when they go awry. When blood vessel integrity is compromised, they become weaker and can rupture, which can be fatal.
By knowing what vessels are susceptible and under what conditions, they can identify disease links that may be predictable and lead to the development of therapeutic interventions.
“The competition for these grants is fierce, and you must have an incredible track record to be considered for one of them,” said OMRF President Stephen Prescott, M.D. “The NHLBI is betting on Dr. Griffin, and she is an outstanding choice for this award. I have no doubt she will reward them with her incredible work.”
The grant, No. R35 HL144605, is from the NHLBI, a part of the National Institutes of Health.

Medi Flight: Up in the Clouds

by Vickie Jenkins, Staff Writer
If you find yourself looking for James Brigida, you will most likely have to look up in the sky. He will be one of the three crew members on the Medi Flight helicopter. James is a Flight Nurse and a National Registered Paramedic.
Born in Las Angeles, CA and raised in the bay area, James was in his early twenties when he decided to visit a cousin in Oklahoma. He liked Oklahoma so much, he decided to move here and go to nursing school. That was sixteen years ago and he has enjoyed his job ever since. Having a job as a paramedic in 1998, he soon had the opportunity to be a flight paramedic. From there, he became an RN, and then a Certified Flight Registered Nurse. “I was getting great critical care experience and good basic knowledge. Now, I work for Medi Flight based out of Chickasha, OK and the parent company, Air Methods is based out of Denver, CO,” he said.
James explained how the helicopter crew consisted of one pilot, one nurse and one paramedic. “We have to do some life-threatening actions. There are two different types of flight emergencies calls. 1. Scene flight; a call made by a firefighter or a policeman. 2. Transfer call; these are the phone calls usually coming from smaller towns where there is no hospital; needing to transfer the person by helicopter,” James said. “Either way, the flight nurse and paramedic have to know what to do, how to do it and when to do it. We have seconds to take care of that patient in a unique and isolated situation while we are 1,000 feet in the air. We have to have critical thinking skills, performing emergency procedures. Seconds count! The flight nurse and flight paramedic work as equals,” he added.
“Flight nurses have bits of the same schedule as a firefighter. We work 24 hours, twice a week. We have eight flight nurses and eight flight paramedics with four shifts, rotating the schedule. Medi Flight is at Grady Memorial Hospital in Chickasha, OK. Mr. Deacon Vice is the Medical Director of the ER there,” James commented.
Does the helicopter fly in any weather? “Actually, the pilot of the helicopter is like a weatherman. They have to know all of the weather conditions before taking off. There has to be 1,000 feet from the ground to the ceiling (clouds) and be able to see two miles ahead for visibility. In the winter, they have to watch for the helicopter freezing over,” James replied.
Asking James to describe himself, he said, “I’m an outgoing, passionate guy that has a true desire to help. I am a great team player and have a lot of empathy for others.”
What advice would you give to someone if they wanted to be a flight nurse? “I would encourage them to start out by getting experience in the critical care unit. The reason is the fact that all of this training and experience will get them closer to becoming a flight nurse. Also, get all of the certifications you can. It will be even better when you try to get a job as a flight nurse,” James answered.
James isn’t always up in the sky though. “I also have a second job,” James said. “I work at the OU Trauma Center in the ER. This is the one and only Trauma Center in Oklahoma. I am blessed to have a job that I love, doing what I love to do, helping others and fulfilling my passion for flying.”
Living in Edmond, OK, James is married to the love of his life, Patty. They have three children, Matthew, 18, Dante, 20 and Alejandra 22.
James’ hobbies include exercise; working out at a great place called True Grit in Edmond, OK. “It can be a great stress-reliever,” James said. “That’s pretty much my hobby. Working out and sleeping. I love to sleep,” he said with a laugh.
From the days of his childhood, dreaming of aviation and flying, James is blessed to have the title Flight Nurse. “I get to take care of patients and fly in a helicopter. I continue to learn and use my critical thinking skills in my everyday job. I have a wonderful family and I continue to help others in any way that I can, in the air and on the ground,” James said.
Asking James to sum up his life in one word, he answered, “passionate”.
Searching for new arthritis treatments

Arthritis is the leading cause of disability in adults in the U.S., affecting more than 54 million people with more than 100 distinct types of the disease.
To make matters worse, there are no approved treatments for the most common form of arthritis—osteoarthritis. It stems from the loss of cartilage between bones and joints and will affect more than half of all Americans over the age of 65.
Understandably, this has led to much concern about the future of arthritis treatment.
“We all want to live long enough that we eventually have some wear-and-tear form of arthritis,” said Oklahoma Medical Research Foundation Vice President of Clinical Affairs Judith James, M.D., Ph.D. “But we don’t want any disability or limitations from it that tend to occur as we age. What we need is a disease-modifying drug.”
James, a rheumatologist and internationally recognized expert on arthritis, said that advancements in treating other forms of arthritis offer hope for similar developments in osteoarthritis.
“In the past decade, we have seen big changes in treatment for several types of arthritis, including the introduction of drugs and interventions for less-common forms like rheumatoid arthritis,” said James.
Rheumatoid arthritis is a chronic illness mainly characterized by inflammation in the lining of the joints, and it affects more than 1.3 million adults in the U.S. James currently serves as principal investigator on a clinical trial called StopRA, a prevention study for the disease.
“We are testing people who are at high risk of developing RA. Our goal is to get them on treatments that may help prevent the disease from ever occurring,” she said. If you are interested in participating or finding out more about the study, please call 405-271-7745 or email jackie-keyser@omrf.org.
The National Institutes of Health invests more than $500 million annually toward understanding and treating various forms of arthritis. Some of that work is happening at OMRF, including research by scientist Tim Griffin, Ph.D., who studies the effects of obesity on the development of osteoarthritis.
“Much of what we initially learned about osteoarthritis came from studying end-stage diseased tissues when people had their joints replaced,” said Griffin.
However, technological advances in imaging and biomarkers have allowed scientists to study earlier stages of disease. Griffin says that this has given new hope for a cure.
“We now think of early-stage OA as resulting from a family of different conditions, such as obesity, trauma, or aging,” he said. “Treatments that target the specific cause of osteoarthritis at the early stages may delay or even prevent disease.”
Multiple studies have shown that a diet avoiding inflammatory foods like saturated fats and refined carbohydrates can help protect you. Griffin’s lab recently found that diets high in saturated fats increased the risk of joint inflammation in mice—even before cartilage loss began.
“We are working on this disease in earnest and continue to understand more and more about it,” said James. “I am increasingly hopeful that we will see a treatment for osteoarthritis in our lifetime.”
But while we await the first osteoarthritis drug, what can we do in the meantime?
“‘Move as much as you can,” said James. “The more you sit, the stiffer and more painful your joints become. Other keys are to maintain a reasonable body weight and participate in joint-safe exercises like swimming or using an elliptical machine.”
SAVVY SENIOR: Getting Old Pays Off
Dear Savvy Senior,
What types of discounts are available to baby boomers, at what age do they kick in, and what’s the best way to go about finding them? Almost 50
Dear Almost,
One of the great perks of growing older in America is the many discounts that are available to boomers and seniors.
There are literally thousands of discounts on a wide variety of products and services including restaurants, grocery stores, travel and lodging, entertainment, retail and apparel, health and beauty, automotive services and much more. These discounts – typically ranging between 5 and 25 percent off – can add up to save you hundreds of dollars each year.
So, if you don’t mind admitting your age, here are some tips and tools to help you find the discounts you may be eligible for.
Always Ask
The first thing to know is that most businesses don’t advertise them, but many give senior discounts just for the asking, so don’t be shy.
You also need to know that while some discounts are available as soon as you turn 50, many others may not kick in until you turn 55, 60, 62 or 65.
Search Online
Because senior discounts frequently change and can vary depending on where you live and the time of the year, the Internet is the easiest way to help you locate them.
To do a search, start by visiting SeniorDiscounts.com, which lists thousands of discounts that you can search for by city and state, and by the category you’re interested in, for free.
You can also look for discounts at TheSeniorList.com, which provides a large list of national and regional business chains that offer them, or you can Google them individually. Just go to Google.com and type in the business or organization you’re curious about, followed by “senior discount” or “senior discount tickets.”
If you use a smartphone, another tool is the Sciddy app (see Sciddy.com) that lets you search for senior discounts and can send you alerts when you’re at an establishment that offers them.
Join a Club
Another good avenue to senior discounts is through membership organizations like AARP, which offers its 50 and older members a wide variety of discounts through affiliate businesses (see AARPdiscounts.com).
If, however, you’re not the AARP type, there are other alternative organizations you can join that also provide discounts such as The Seniors Coalition or the American Seniors Association. Or, for federal workers, there’s the National Active and Retired Federal Employees Association.
Types of Discounts
Here’s an abbreviated rundown of some of the different types of discounts you can expect to find.
Restaurants: Senior discounts are common at restaurants and fast food establishments – like Burger King, Chick-fil-A, Subway, Wendy’s, Applebee’s and Golden Corral – ranging from free/discounted drinks, to discounts off your total order.
Retailers: Many thrift stores like Goodwill, and certain retailers like Banana Republic, Kohl’s, Michaels and Ross stores offer a break to seniors on certain days of the week.
Supermarkets: Many locally owned grocery stores offer senior discount programs, as do some chains like Albertsons, Kroger, Publix and Fry’s Supermarkets, which offer some discounts on certain days of the week but they vary by location.
Travel: Southwest Airlines provide the best senior fares in the U.S. to passengers 65 and older, while Amtrak offers a 15 percent discount and Greyhound offers 5 percent off to travelers over 62. Most car rental companies provide discounts to customers who belong to organizations like AARP. Royal Caribbean, Celebrity and Carnival cruise lines offer discount rates to cruisers 55 and over. And, most hotels offer senior discounts, usually ranging from 10 to 30 percent.
Entertainment: Most movie theaters, museums, golf courses, ski slopes and other public entertainment venues provide reduced admission to seniors over 60 or 65. And the National Park Service offers a lifetime pass for those 62 and up for $10 (see nps.gov/findapark/passes.htm).

A community near you: Integris launches new concept
by Bobby Anderson
Staff Writer
A new healthcare delivery concept partnering Integris and Emerus Holdings, Inc. is popping up all over the metro.
And the move is creating more options for local nurses.
As part of its expansion initiative, Integris, the state’s largest nonprofit health care system, entered into a joint venture partnership with Emerus, the nation’s first and largest operator of micro-hospitals, to build and manage four new community hospitals.
“Oklahomans have told us they want quicker, more convenient medical care without compromising quality or safety,” said Timothy Pehrson, president and chief executive officer at Integris. “These community hospitals allow us to do just that, bring high-quality care closer to home for many of the residents we serve.”
In February, Integris Community Hospital at Council Crossing, 9417 N. Council Road., opened followed by Integris Moore Community Hospital at 1401 SW 34th St. at the end of the month.
In March, Integris Del City Community Hospital, 4801 SE 15th St, began accepting patients.
Later in May, the Integris OKC West Community Hospital at 300 S. Rockwell Ave., will open.
Emerus Holdings Inc., is the nation’s first and largest operator of these small-format facilities and promises the new sites will bring a transformative concept of health care to Central Oklahoma.
Emerus Chief Executive Officer Craig Goguen said the company is honored to partner with INTEGRIS, an award-winning, highly respected health system brand, as it expands its footprint throughout central Oklahoma.
“Our transformative concept of health care allows great health systems like Integris to expand its reach into the community to provide a variety of patient services that are fast, convenient and economical,” Goguen said.
Christopher McAuliffe, BSN, MBA, RN, CAPA is the Emerus market chief nursing officer and says the new concept will bring options for both consumers and health care workers.
“In addition to serving areas considered underserved in their healthcare needs, the small-scale, fully licensed inpatient hospital is open 24 hours, seven days a week,” McAuliffe said. “It is conveniently located in communities where patients live, work and play, providing them with quick and easy access when they have emergency medical needs. If the patient requires additional specialty services, working with our partner, INTEGRIS Health, we can quickly access appropriate services and make transfers, as needed.”
McAuliffe said the concept is using the same electronic medical record system used by Integris.
The small-scale inpatient hospital provides many efficiencies resulting from its smaller footprint. Parking is ample and accessible, compared to the large hospital setting.
“There are several resources, from a clinical standpoint, that improve quality of care,” McAuliffe said. “We have a CT/X-ray room dedicated specifically to our patients. We do not do any outpatient diagnostics, leaving the RT to focus only on those patients who come through the ED or an ordered inpatient test.
“We also have staff cross-trained to do many different roles. All clinical staff, RT, ED Tech and Nursing staff are thoroughly trained in our lab. This allows us to quickly complete a lab order, from start to finish, without having to wait on the tube system or on another department in a remote location to complete.”
McAuliffe stressed that the hospitals will operate through a teamwork concept that has Emerus numerous awards including the Guardian of Excellence Award for Superior Patient Experience from 2013 to 2017.
These new community hospitals will serve a variety of patient needs including emergency medical care, inpatient care and other comprehensive health services. While the ancillary services vary, each community hospital has a set of core services including the emergency department, pharmacy, lab and imaging.
The rest of the services depend on the needs of the community, but common examples include primary care, dietary services, women’s services and low-acuity outpatient surgeries. The community hospitals offer:
* Health system integration — allowing for care coordination, consultation and seamless transition across the care continuum
* Fully licensed as a hospital and subject to all hospital conditions of participation and regulatory requirements
*Emergency-trained physicians and outpatient ambulatory clinical services on site — ensuring patients receive the highest quality care, when they need it
* Inpatient bed capacity — allowing patients to stay closer to home when lower level admissions/recoveries are needed
* All patients accepted without regard to insurance or ability to pay, including Medicare, Medicaid and Tricare
* Community-based hospitals open 24 hours a day, seven days a week – offering ease of access to our patients
“The joint venture with Integris greatly benefits patients,” McAuliffe said. “In the metro, several of the Integris facilities have been experiencing large volumes of patients, resulting in some challenges. Our 32 additional inpatient beds allow Integris the opportunity to have additional clinical resources.
“The 32 additional ED beds help reduce the strain on the often overcrowded Emergency Rooms Integris frequently experiences.”
Polishing an Emerald: Heart Living Centers shine

by Bobby Anderson
Staff Writer
Polly Milligan officially started her career in senior health as a dietary aide in a small Perry, Oklahoma residence as a young girl.
But truth be known the executive director of Emerald Square Assisted Living in Oklahoma City was born for working with seniors.
“I’ve literally known nothing else my entire life other than geriatrics,” Milligan said. “This is where I’m comfortable, this age group. I fit right in.”
That first dietary aide position quickly advanced when the dietary manager took ill and Milligan stepped in.
“One day no one showed up to work the floor and they said they needed some help,” Milligan said. “I did that and the steps kept going.”
The experiences of a lifetime spent taking care of others has landed her in the driver’s seat at Emerald Square Assisted Living where new ownership is investing in renovation and expansion with an eye on becoming the leading choice for thoughtfully-planned senior living in the metro.
A NEW HEART
With two decades spent in senior living, Milligan was comfortable right where she was at, leading a local residence owned by a nationwide company.
That was before the owners of Heart Living Centers called.
“I’m not one for small corporations much but there’s just something about this husband and wife that started this that I just knew was right,” Milligan said of the Colorado-based Heart Living Centers.
As the owners shared their passion for what they were doing, Milligan began to open up about hers.
“I was adopted by my grandmother when I was six weeks old out of an orphanage,” Milligan said. “My mother and father, when they divorced, neither wanted the kids. There were three of us so they put us in an orphanage.”
“My mother was 67 years old when she adopted me and she was taking care of her two oldest sisters.”
Due to her age, the orphanage would only let Milligan’s new mother, a Pentecostal preacher, adopt one child.
“Being an infant girl, she knew if I got adopted she would never see me again so she adopted me and bought the house across the street to the orphanage so she could stay next door to my brothers,” Milligan said.
Milligan still remembers going across the street every day to play with her siblings at the orphanage.
It was all about family and honoring that bond.
Milligan has carried that with her ever since, building relationships wherever she has gone.
At Emerald she called on those relationships to begin putting her touch on the facility immediately.
VETERAN APPROVED
Milligan leads one of only a handful of residences in the metro that carries a special Veteran’s Administration approved designation.
“We have a lot of veterans here,” Milligan said. “The VA’s representatives come here frequently and visit their veterans and insure their needs are met. If we need something for them we can just call them and they will bring it to us. They take care of their transportation to their doctor’s visits.”
“It’s a whole working system.”
The designation means that approximately half of Emerald’s residents have served our country with pride.
Building on that program is on her to-do list.
Overseeing construction of more independent cottages in the back of the facility is also on her radar.
A new memory care will soon be offered.
“I’m so excited,” Milligan beamed. “It totally has blown my mind.”
Milligan’s staff is all hand picked through her years of experience in the industry.
They’ve helped initiate resident-favorite amenities.
Soon, Emerald Square residents will experience all-day dining, allowing them total control of when and what they will eat.
“It’s essentially a restaurant open from 6 a.m. to 8 p.m. at night,” Milligan said. “They’ll be able to order and eat whenever they are ready.”
There so much excitement around Emerald Square right now but some things will not change.
“The biggest thing is I have one expectation,” Milligan began. “The expectation I have of everyone is to take care of the residents to the best of your ability. Everything else will take care of itself. Your finances will be fine. Your staff will be happy. Your residents will be happy.”
“You have to provide the best care you can. You never tell a resident they can’t do something. You find a way to make it happen because we are in their house.”

OU Medicine Neurosurgeon First To Use Lifesaving Stent on Aneurysms
Aneurysms in the brain are dangerous because, if they rupture, patients face a significant chance of dying within six months. To decrease that possibility, OU Medicine neurosurgeons are using a new medical device to prevent aneurysm rupture and recurrence — without major surgery opening a patient’s skull. Neurosurgeon Bradley Bohnstedt, M.D., has been using the Surpass Streamline Stent to divert the flow of blood away from an aneurysm, which greatly decreases its potential for rupture. The procedure is minimally invasive – via a catheter, the stent is inserted into a blood vessel near the groin, then Bohnstedt directs it all the way up to the aneurysm in the brain.
OU Medicine was the first in Oklahoma to place the Surpass Stent in a patient. The advantage of the device is that it is designed to treat larger aneurysms in more areas of the brain. The technology is called “flow diversion” for its ability to route blood away from the aneurysm.
“By diverting the flow of blood away from the aneurysm, it reduces the stress on the wall of the aneurysm and allows it to heal and shrink,” Bohnstedt said. “In six months to a year, the aneurysm takes on the normal shape of the blood vessel.”
Bohnstedt describes aneurysms as blisters on the side of a blood vessel. If an aneurysm ruptures, 10 percent of patients will die before they make it to a hospital. Up to 50 percent of people whose aneurysms rupture will die by six months because of ensuing complications, Bohnstedt said.
Because of readily available imaging techniques, physicians are finding more aneurysms today than ever before. Some aneurysms are small and never need to be treated, Bohnstedt said, but others are risky to the patient.
“It’s important when we identify aneurysms that we stratify their risk for rupture to determine which ones need to be treated,” he said. “Then we want to treat them sooner rather than later.”
The treatment of aneurysms has evolved as technology has improved. Traditionally, Bohnstedt would open up the patient’s skull and place a clip on the aneurysm to prevent its rupture. He still performs that surgery when necessary but, while effective, it is invasive and leads to a long recovery for the patient. With the advent of endovascular techniques, neurosurgeons gained a minimally invasive method of accessing an aneurysm by traveling through the blood vessels. The first and second generations of endovascular treatment involved placing coils made of platinum inside the aneurysm to keep the blood flow at bay. With this technique, patients faced far less recovery time, but the aneurysms recurred about 40 percent of the time.
The Surpass Stent, made of metal, is greatly improved in all areas – it works well for larger, more distant aneurysms and, once treated, they don’t seem to return.
“We’re treating far more aneurysms with the Surpass Stent than we previously treated,” Bohnstedt said. “We also hope to be involved with the study for the next generation of the Surpass device, which will have the ability to treat even more sizes of aneurysms in additional parts of the brain. OU has been an early adopter of new technologies after FDA approval, which allows our patients to be a part of research studies for devices that aren’t readily available to the public.”
