Crook County offers diabetes prevention program – KTVZ

Posted: May 2, 2017 at 1:43 pm

Diabetes is on the rise in Crook County. According to the most recent County Health Rankings, Crook County has one of the highest diabetes rates in Oregon, and it has been climbing steadily over the last 6 years. This may be due in part to our aging population.

Individuals over the age of 65 are at a higher risk for diabetes, and its precursor, prediabetes. Lack of physical activity is also another major risk factor. 19% of Crook County adults report getting zero leisure time physical activity.

In September, the Crook County Health Department launched a Diabetes Prevention Program called Prevent T2 to help reduce rates of type 2 diabetes. Prevent T2 is a class for people with prediabetes or who have other risk factors for type 2 diabetes. People with prediabetes higher-than-normal blood glucose (sugar) levels are 5 to 15 times more likely to develop type 2 diabetes than those with normal blood glucose levels. In fact, many people with prediabetes can be diagnosed with type 2 diabetes within 5 years.

Prevent T2 is a program developed by the CDC. It is based upon research that showed that people with prediabetes who lost 5 to 7 percent of their body weight (10 to 14 pounds for a 200-pound person) by making modest lifestyle changes reduced their risk of developing type 2 diabetes by 58 percent. For persons over the age of 60 their risk is cut by 71%.

In the program individuals work with a trained lifestyle coach to learn how to eat healthy, add physical activity to their routine, manage stress, stay motivated and solve problems that can get in the way of healthy changes. Prevent T2 groups meet for a year weekly for the first 6 months, then once or twice a month for the second 6 months to maintain healthy lifestyle changes. Participants of the group that started in September have finished the first 6 months and many have reached their weight loss goals.

The most valuable part of this class for me has been knowing that I have accountability to someone and that it is an extended period of time," said Sue Barnhouse, a current class participant. The information presented in the class has been valuable and given me a reason to continue to make changes in my activity and eating habits that really do make a difference in how I feel.

Crook County Health Department will be offering another class starting May 25th. in partnership with St. Charles. This new class will meet Wednesdays from 5:15 6:30pm at the IronHorse Lodge community room 435 NE Wayfinder Dr. Prineville. The class will be led by two trained lifestyle coaches, Kylie Loving the Diabetes Prevention Coordinator for Crook County, and Carlyn Young, a registered dietitian at St. Charles in Prineville. This class free and open to the public. Interested individuals can come to the first class May 25th to learn more and sign up for the program.

Prediabetes is a condition that often goes undiagnosed, but it is estimated that one in three Americans has it. People are more likely to have prediabetes and type 2 diabetes if they:

Are 45 year of age or older;

Are overweight;

Have a family history of type 2 diabetes;

Are physically active fewer than three times per week;or

Have been diagnosed with gestational diabetes during pregnancy or gave birth to a baby weighing more than 9 pounds.

To participate in the Prevent T2 program, a person must be 18 years of age or older, have a clinical diagnosis of pre-diabetes, or have the risk factors listed above.

Muscatine Diabetes Walk Project funds support, research – Muscatine Journal

Posted: May 2, 2017 at 1:43 pm

MUSCATINE Kim Seligman has had a busy year.

Her organization, the Muscatine Diabetes Walk Project, rolled out several programs, including a year-long wellness and nutrition diabetes prevention program and two monthly support groups for Type 1 and Type 2 diabetics. With several more programs in the pipeline, including cooking classes and a diabetes prevention program for third graders, Seligman hopes to live up to her mission to support, empower and encourage diabetics in Muscatine County.

On Friday, Seligman will celebrate that progress with the second annual Muscatine Diabetes Walk. Seligman, whose late son was a Type-1 diabetic, has made it her goal to connect people living with diabetes with the resources and support they need.

I know that these programs and outreach activities were needed in the community and it feels good just to see them coming to fruition and being able to support individuals that live with all types of diabetes here in Muscatine County, she said.

The annual walk was one of the first things Seligman did 13 years ago when she decided she wanted to support people living with diabetes. Initially, she partnered with the Watermelon Stampede to raise money for diabetes research. The annual walk evolved from there, but last spring it became the Muscatine Diabetes Walk, with the majority of the funds raised from the walk going to support programs in Muscatine.

Ninety-five percent of this years proceeds, she said, will go toward local programs, with 5 percent going to diabetes research.

I think (diabetics) need to feel that someone cares about them, she said. Living with diabetes 24/7 is not an easy journey and this is one way that we can celebrate all individuals that live with diabetes and let them have a fun event, come and feel loved by the community, supported by the community and just let them know the programs that we have available for them.

At the walk, Seligman will highlight some of her community partners, including Hy-Vee, whose dietician helps with the diabetes support groups, and UnityPoint HealthTrinity Muscatine, whose clinicians assist with the diabetes prevention program.

Seligman said there is still much to be done in Muscatine County.

I definitely want to see our Muscatine diabetes prevention program grow; we definitely want to grow that program, she said. We want to reduce the percentage of individuals that are at risk for pre-diabetes and Type 2 diabetes here in Muscatine County.

As she has thus far, Seligman hopes to collaborate with organizations who offer wellness services and connect people with services already available to them.

There are many good things (in the community) and its just connecting everything together, she said. If thats what our purpose is, I am so excited about that.

7-year-old Hollis spread joy around U.S. After losing him to rare brain tumor, parents turn to finding cure – AZCentral.com

Posted: May 1, 2017 at 4:44 am

Shawnee and Shane Doherty of Phoenix, who lost their 7-year-old son to a form of brain cancer, talk about their boy, Hollis, his zest for life, and the need for more research. Tom Tingle/azcentral.com

Hollis Doherty was a star elementary-school athlete, but not forthe reasons you'd think.

"He wasn't necessarily the most skilled player ...but he was like the fun kid; he was the cheerleader," said his mother, Shawnee Doherty.

He was the first kid ever to be on the championship-winning baseball, basketball and football teams in one year in his uptown Phoenix program, but photos usually show him running around and laughing on the field, no ball in sight.

Hollis Doherty was 7 years old when he died of a rare brain tumor.(Photo: Dacia Rolando/Special for The Republic)

"He called himself 'Hollis the Hugger' because he was always hugging everybody, hugging strangers,"Doherty said.

He was a healthy kid with perfect attendance in school, so it was strange when Hollis had his first bad headache in March 2016.He visited doctors and had tests done, but everything came backnormal, so the pain was considered a migraineor a virus.

Then, about a week later during baseball practice, Hollis fell to the ground and began screaming in pain.

An MRI revealed a tumor on Hollis'brain stem. He was diagnosed with diffuse intrinsic pontine glioma, or DIPG,on March 29, 2016.

DIPG is a aggressive brain tumor that almost exclusively affects children. It is difficult to treat, has no cure and "interferes with all bodily functions, depriving a child of the ability to move, to communicate, and even to eat and drink,"according todefeatdipg.org.

Hollis never reached that point. Instead, he lived happily, andjust a couple days after sledding in northern Arizona last winter with his parentsand 10-year-old brother, Rhett, he fought a brief battle with his symptoms and died on Jan.2.

He was 7 years old.

Now, his parents are hoping to keep his memory alive and use their experience to help others affected by this fatal disease, planning fundraisers this spring to research his tumor and his treatment in hopes of helping other kids like him.

The Dohertys' home in the FQ Story Historic District in central Phoenix has a University of Arizona flag the place where Shane and Shawnee met and fell in love hanging near the entrance. On a recent March afternoon, Rhett kicked off his fourth-grade spring break by laughing at YouTube videos in his room.

Thehouse is decked out in green, with four-leaf clovers and shamrocks everywhere. The Dohertys are Irish and Scottish, so when they made a Facebook page called Hope for Hollisthe day after his diagnosis, they first used a green heart as a logo, and later a four-leaf clover with hearts in it.

As the popularity of Hollis'Facebookpage grew, athletes and celebrities, such as world-renowned golfer Jason Day and Olympic gold medalist Kerri Walsh Jennings, began taking photos of themselves with an H for Hollis written on their hand as a way to bring Hollis joy and spread the word about DIPG.

Even comedian Will Ferrell sent Hollis a video, in which he said:"(I) put on a fancy tuxedo for you, because I know youre a very fancy person. Youve been rumored to wear a lot of tuxedos all the time, and you have very polite manners and wonderful etiquette at the dinner table."

"When he was alive he would tell people, 'I'm internet famous,' " Shane said, chuckling. "Sometimes, there's kids that just touch people, and... Hollis was one of those."

DIPG is so devastating, in part, because it is generally considered inoperable. It is risky to take a biopsy from the brain stem, and the tumor isn't one solid mass but instead is spread out, intermingled with healthy cells. There is little treatment and no cure.

Hollis underwent radiation to shrink his tumor, allowing him to function better and more comfortablyuntil it would inevitably grow back. After that, he and his family traveled to Germany one week every month for him to receive relatively non-invasive immunotherapy. Buthe never had surgery or chemotherapy, and never lived in the hospital.

Instead, Shane and Shawnee focused on giving Hollis the "mostbest days."

"Some of the families who are going through this remove themselves from reality and start a bucket list, but for a 7-year-old, Idont know what a bucket list would look like. For him, you know, we just had to decide to give him as normal a childhood as we could," Shawnee said. "He was smart enough that we knew if we veered away from this sense of normalcy that he would understand why."

That meant going to school, riding the bus, eating lunch with his friends and doing homework, even while in Germany. Last Halloween, he walked his neighborhood dressed up as a blue ninja.

ForHollis, many of his best dayswere in sports.

"Even though he was still battling this, he still was able to win a championship in basketball in his youth league;he was able to win a championship in his flag football league," Shane said."Two weeks before he passed away, he ran a full 20 minutes on the basketball court with his basketball team."

"So he lived, and that's what gave him most best days in the eyes of a 7-year-old child."

Hollis threw the opening pitch at an Arizona Diamondbacks game, metthe team and toured behind the scenes at the stadium. He dropped the puck at an Arizona Coyotes game and met Arizona Cardinals players.

Hollis'bedroom is decked out in sports memorabilia made especially for him: a framed Cardinals jersey with his name on it and a photo of the family on the field, a framed green Diamondbacks jersey that says "Hope 4 Hollis" with an engraved plate that says "Hollis, welcome to the team!"

"I often think that if it wasnt captured on the internet, his friends wouldnt believe him at school the next day, 'cause, you know, some of what he got to experience was a once-in-a-lifetime thing," Shawnee said.

Hollis didn't have another headache until Dec. 28. A couple days later, the family traveled to Flagstaff, where he wentsledding and shot BB and pellet guns before suffering another one. He was admitted to the hospital on New Year's Eve and, after a brief battle, died with his family at his side.

"I dont know if he ever was afraid he was going to die," Shawnee said."I think he just was in the hospital and then, next minute, was in heaven."

About 3,000 people packed Living StreamsChurch for Hollis'memorial service in January, and another 1,500 watch the livestreamon the church's website.

In the following weeks, Hollis'classmates made a book for the family of their favorite memories of him. The Dohertyskeep it in his room.The vast majority of the entries were about his love of reading, with one child even writing the he had "3,000 books."

"My favorite memory about Hollis is that he was very funny," one boy named Emiliowrote, along with a drawing of Hollis saying "sup dood" and laughing."Hollis loved to read books. I will always remember Hollis' smile and his hugs. Hollis was a really good friend."

Moments after doctors told Shane and Shawnee about Hollis'diagnosis last year, they called Dr. Michael Berens, a church friend who also is head of the Glioma Research Lab at theTranslational Genomics Research Institute, or TGen, in Phoenix.

Berens is a brain-tumor scientist who, although a researcher and not a medical doctor, often counsels families through diagnosis, informing them of the newest and best in the science of the disease.

Hewas the one who encouraged the Dohertys to make decisions with the "most best days" philosophyand talked extensively with their doctor in Germany before giving his stamp of approval.

"When I would track with Hollis I was thinking, Hes having incredibly best days. It was startling to me, and thats not typical for DIPG. Those kids tend to have very progressive erosion of the scale of their lives," Berens said, pausing. "He had an amazing, brief, high-quality life."

He and his wife visited Shane and Shawnee in the hospital moments before Hollis died. When he passed, they called Berens to donate Hollis'tumor to his lab.

"It was actually one of the few lab meetings we've had where more than a few people were in tears," Berens said.

Afterraising more than $123,000 on their GoFundMe pagefor Hollis'treatment and covering all oftheir costs, Shane and Shawnee donated $30,000to TGenso that Berens and his team could study the genetics of Hollis'tumor, compare it to others and see if the immunotherapy he received had any impact.

"Im looking to try to help them on their journey of grief, and that typically is not what a research lab is going to do. But as a friend, I have an opportunity" to help them understand what happened and to advance the body of knowledge on the disease, Berens said.

Government funding and budgeting leaves little money for pediatric-cancer research and even less specifically for DIPG.Instead, much of the funding for DIPG research comes from families devastated by the disease.

"It's families like us that are just pissed off and their kids are dead that are bringing this change," Shawnee said."Like with TGen, we're trying to move the needle. That's it. It's taking the families who are becoming advocates to say, 'No more.' "

Astronaut Neil Armstrong lost his daughter to DIPG, and former Chicago Bears running back Adrian Peterson lost his son. One of the largest DIPG foundations in the country is theChadTough Foundation on behalf of Chad Carr, the grandson of formerUniversity of Michiganfootball coach Lloyd Carr.

Yet, little progress has been made against the disease in the last 40 years.

The Dohertys are hoping to change that. They're currently working to raise $200,000 for a second phase ofresearch to begin later this year.

Instead of joining an existing trial, they want to try something innovative, like focusing on the immune-system therapy Hollis received in Germany that may have helped stave off his symptoms.

Berens intends to assemble ateam ofDIPG researchers and clinicians to design a clinical trial in which each patient with DIPG will receive personalized therapies designed to help their own bodies fight the tumor, in hopes of giving them the "most best days."

The Dohertys have a few fundraisers planned for this spring, which are noted on their Facebook page.

On Saturday, the Diamondbacks are hostingHope Through Hollis Nightduring their game against theColorado Rockies. For every ticket sold through groupmatics.events/event/hollis, the team will donate $10 to the Hope Through Hollis Fund at TGen.

Anyone who buys the fundraising tickets can participate in a pre-game parade on the field by lining up outside Gate J near Section 110 by 3:45 p.m.The Dohertys will be part of the parade and welcome anyone to walk with them, especially kids, Shawnee said.

Those who wantto support the cause but can't attend the Saturday game can buy adiscounted $25 ticket voucher good for any home game after May 1.

"The Dohertys hold a special place in our hearts, and they have become a part of our baseball family that is closer than any other,"Diamondbacks President and CEO Derrick Hall said.

May 7 isTGen's seventh annual Cycle for the Cure, a one-day fundraiser consisting of indoor cycling and yoga classes at five locations in Phoenix, Chandler and Scottsdale. There are still spots open on the Hope For Hollis cycling team, or people can sponsor the riders, including Shawnee. Learn more attgenfoundation.org/cycle.

The last fundraiseron their schedule so far is the Hope Through Hollis Golf Tournament and Family Event on May 20 atLongbow Golf Course in Mesa. Cost for a single golfer is $150, and they are still seeking sponsors for the event. Find more information on theFacebook pageor athth.accelraising.com.

Anyone also can donate to the Hope Through Hollis Fund at TGen directly attgen.org/hollis.

Advances in science, many of them from scientists at USDA or through research funded by USDA, have opened up new options for farmers responding to market needs and environmental challenges. Many new plant varieties being developed or grown by farmers have been produced using genetic engineering, which involves manipulating the plant's genes through techniques of modern molecular biology often referred to as recombinant DNA technology. These techniques are included in what is often referred to as "biotechnology" or "modern biotechnology."

USDA supports the safe and appropriate use of science and technology, including biotechnology, to help meet agricultural challenges and consumer needs of the 21st century. USDA plays a key role in assuring that biotechnology plants and products derived from these plants are safe to be grown and used in the United States. Once these plants and products enter commerce, USDA supports bringing these and other products to the worldwide marketplace.

Three federal agencies are involved in ensuring that plants produced using biotechnology and the many products derived from them are safe for farmers to use, safe to consume as food or feed, and safe for the environment. These are USDA's Animal and Plant Health Inspection Service, the Department of Health and Human Services' Food and Drug Administration, and the United States Environmental Protection Agency. The three agencies regulate these products based on the characteristics of the actual products and their intended uses, and they operate under the existing laws passed by Congress to ensure the safety of plants used in agriculture, the safety of pesticides used in agriculture, and the safety of foods we eat and feeds given to animals. Many other USDA agencies have roles in the development, use, and marketing of these products as well.

Learn more about How the U.S. Government Regulates Biotech Plants.

Since the first successful commercialization of a biotechnology-derived crop in the 1990s, many new crop varieties have been developed and made available to U.S. farmers and farmers worldwide. U.S. farmers have rapidly adopted many of these new GE varieties, so that in 2012, 88 percent of the corn, 94 percent of the cotton, and 93 percent of the soybeans planted in the U.S. were varieties produced through genetic engineering. A large proportion of the production of other crops, such as alfalfa, and papaya, and sugar beet, is also biotech-derived.

Read more about the reasons behind this trend and about how farming practices and the marketplace have changed on USDA's Economic Research Service Biotechnology page.

The United States is the largest exporter of agricultural products, which helps feed the world's population, and our export markets are critical to the health of U.S. farm communities around the country. Most of the corn and soybeans we export are biotechnology-derived, and this means that working with our trading partners is critical to help them understand the technical aspects of new products and how we have determined that they meet our high safety standards, to open up new markets, and to ensure that our products are treated fairly in the global marketplace.

The increasing use of biotechnology in agriculture has changed, and will continue to change, farming and the work of USDA in the long-term. To help understand and address these changes, USDA established the Advisory Committee on Biotechnology and 21st Century Agriculture (AC21). One critical area where the committee has focused its attention is how farmers who produce different crops intended for different customers-biotechnology-derived, conventional, or organic-can best co-exist and produce the crops that meet their customers' needs. The AC21 has provided a report to USDA, with recommendations, on this subject.

3SBio: Is this Chinese Biotechnology Stock a Buy? – Barron’s (blog)

Posted: May 1, 2017 at 4:42 am

By Isabella Zhong

Shenyang-based 3SBio (1530.HK) is a biopharmaceutical pioneer that offers a unique play on Chinas rising demand for healthcare.

The company is best known for its rheumatoid arthritis drug YSP, which accounts for 33% of revenues, and TPIAO, a hormone used in the treatment of platelet deficiencies.

While YSP and TPIAO are expected to deliver strong sales growth in coming years, a recent price cut for anemia drug EPIAO and limited R&D upside in the near term could weigh on 3SBio. Jefferies analyst Eugene Huang initiated coverage of the stock today with a hold rating and an HKD11.50 a share target price, which implies 11% upside.

Huang has more on 3SBios drugs pipeline:

3SBios HER2 (breast cancer) and CD20 (lymphoma) candidates were withdrawn, leaving peers like Fosun potentially to become FTM generics. Besides, we factored in Rmb20/50/110m 17/18/19E sales from Bydureon (exenatide ER, GLP-1, diabetes), which is pending NDA approval. We are concerned there might be a lack of synergy between 3SBio and AstraZenecas diabetes team as well as integration risks.

Shares of 3SBio are up 37% this year and trade at 23 times forward earnings, which is in line with its five year average. Analysts surveyed by FactSet expect 3SBio to grow earnings at a 28.3% average annual pace over the next three to five years. While the stocks scarcity value and long-term growth potential look appealing, investors may want to wait for a better entry point.

Endothelial progenitor cell – Wikipedia

Posted: May 1, 2017 at 4:41 am

Endothelial progenitor cell (or EPC) is a term that has been applied to multiple different cell types that play roles in the regeneration of the endothelial lining of blood vessels. Outgrowth endothelial cells are an EPC subtype committed to endothelial cell formation.[1] Despite the history and controversy, the EPC in all its forms remains a promising target of regenerative medicine research.

Developmentally, the endothelium arises in close contact with the hematopoietic system. This, and the existence of hemogenic endothelium, led to a belief and search for adult hemangioblast- or angioblast-like cells; cells which could give rise to functional vasculature in adults.[2] The existence of endothelial progenitor cells has been posited since the mid-twentieth century, however their existence was not confirmed until the 1990s when Asahara et al. published the discovery of the first putative EPC.[3]

Recently, controversy has developed over the definition of true endothelial progenitors.[4] Although bone marrow-derived cells do appear to localize to injured vessels and promote an angiogenic switch, other studies have suggested these cells do not contribute directly to the functional endothelium, instead acting via paracrine methods to provide support for the resident endothelial cells.[5][6] While some other authors have contested these, and maintained that they are true EPCs,[7] many investigators have begun to term these cells colony forming unit-Hill cells (CFU-Hill) or circulating angiogenic cells (CAC) instead (depending on the method of isolation), highlighting their role as hematopoietic myeloid cells involved in promoting new vessel growth.[8][9]

Molecular genetic analysis of early outgrowth putative EPC populations suggests they do indeed have monocyte-like expression patterns, and support the existence of a separate population of progenitors, the late outgrowth, or endothelial colony forming cell (ECFC).[10] Furthermore, early outgrowth cells maintain other monocyte functions such as high Dil-Ac-LDL and India ink uptake and low eNOS expression. These original, early outgrowth, CFU-Hill or CACs are also shown to express CD14, a lipopolysaccharide receptor expressed by monocytes but not endothelial cells.[11]

Endothelial colony forming cells represent a distinct population that has been found to have the potential to differentiate and promote vessel repair. ECFCs are now known to be tissue-resident progenitor cells in adults that maintain some vasculogenic ability.[12]

By method of isolation and cell function, three main populations of putative adult EPCs have been described. The behavior of the cells can be found in the following table.[9][13]

EPCs also have variable phenotypic markers used for identification. Unfortunately, there are no unique markers for endothelial progenitors that are not shared with other endothelial or hematopoietic cells, which has contributed to the historical controversy surrounding the field. A detailed overview of current markers can be found in the following table.[2][13]

As originally isolated by Asahara et al., the CFU-Hill population is an early outgrowth, formed by plating peripheral blood mononuclear cells on fibronectin-coated dishes, allowing adhesion and depleting non-adherent cells, and isolating discrete colonies.[8][9]

A similar method is to culture the peripheral blood mononuclear fraction in supplemented endothelial growth medium, removing the non-adherent cells, and isolating the remaining. While these cells display some endothelial characteristics, they do not form colonies.[8][9]

Endothelial colony forming cells are a late outgrowth cell type; that is, they are only isolated after significantly longer culture than CFU-Hill cells. ECFCs are isolated by plating peripheral blood mononuclear fraction on collagen-coated plates, removing non-adherent cells, and culturing for weeks until the emergence of colonies with a distinctive cobblestone morphology. These cells are phenotypically similar to endothelial cells and have been shown to create vessel-like structures in vitro and in vivo.[8][9]

Certain developmental cells may be similar to or the same as other endothelial progenitors, though not typically referred to as EPCs. Hemangioblasts (or their in vitro counterpart, blast - colony forming cells) are cells believed to give rise to both the endothelial and hematopoietic systems during early development. Angioblasts are believed to be a form of early progenitor or stem cell which gives rise to the endothelium alone. More recently, mesoangioblasts have been theorized as a cell giving rise to multiple mesodermal tissues.[14][15][16]

Endothelial progenitor cells are likely important in tumour growth and are thought to be critical for metastasis and the angiogenesis.[17][18] A large amount of research has been done on CFU-Hill bone marrow-derived putative EPCs. Ablation of the endothelial progenitor cells in the bone marrow lead to a significant decrease in tumour growth and vasculature development. This indicates that endothelial progenitor cells present novel therapeutic targets.[19]Inhibitor of DNA Binding 1 (ID1) has been used as a marker for these cells;[20] this allows for tracking EPCs from the bone marrow to the blood to the tumour-stroma and even incorporated in tumour vasculature.

Recently it has been found that miRNAs regulate EPC biology and tumour angiogenesis. This work by Plummer et al. found that in particular targeting of the miRNAs miR-10b and miR-196b led to significant defects in angiogenesis-mediated tumor growth by decreasing the mobilization of proangiogenic EPCs to the tumour. These findings indicate that directed targeting these miRNAs in EPCs may result in a novel strategy for inhibiting tumor angiogenesis.[21]

Studies have shown ECFCs and human umbilical vein endothelial cells (HUVECs) to have a capacity for tumor migration and neoangiogenesis even greater than that of other CD34+ hematopoietic cells when implanted in immunodeficient mice, suggesting the endothelial progenitors play a key role, but further supporting the importance of both cell types as targets for pharmacological therapy.[22]

Higher levels of circulating "endothelial progenitor cells" were detected in the bloodstream of patients, predicted better outcomes, and patients experienced fewer repeat heart attacks,[23] though statistical correlations between these outcomes and circulating endothelial progenitor cell numbers were scant in the original research. Endothelial progenitor cells are mobilized after a myocardial infarction, and that they function to restore the lining of blood vessels that are damaged during the heart attack.

A number of small phase clinical trials have begun to point to EPCs as a potential treatment for various cardiovascular diseases (CVDs). For instance, the year long "Transplantation of Progenitor Cells and Regeneration Enhancement in Acute Myocardial Infarction" (TOPCARE-AMI) studied the therapeutic effect of infusing ex-vivo expanded bone marrow EPCs and culture enriched EPCs derived from peripheral blood into 20 patients suffering from acute myocardial infarction (MI). After four months, significant enhancements were found in ventricular ejection fraction, cardiac geometry, coronary blood flow reserve, and myocardial viability (Shantsila, Watson, & Lip). A similar study looked at the therapeutic effects of EPCs on leg ischemia caused by severe peripheral artery disease. The study injected a sample of EPC rich blood into the gastrocnemius muscles of 25 patients. After 24 weeks an increased number of collateral vessels and improved recovery in blood perfusion was observed. Rest pain and pain-free walking were also noted to have improved [24]

The role of endothelial progenitor cells in wound healing remains unclear. Blood vessels have been seen entering ischemic tissue in a process driven by mechanically forced ingress of existing capillaries into the avascular region, and importantly, instead of through sprouting angiogenesis. These observations contradict sprouting angiogenesis driven by EPCs. Taken together with the inability to find bone-marrow derived endothelium in new vasculature, there is now little material support for postnatal vasculogenesis. Instead, angiogenesis is likely driven by a process of physical force.[25]

In endometriosis, it appears that up to 37% of the microvascular endothelium of the ectopic endometrial tissue originates from endothelial progenitor cells.[26]

Stem cell therapy ‘magic’ for stroke, eye ailments – Vanguard News – Vanguard

In recently published papers in the New England Journal of Medicine about the use of Stem Cell Therapy for Macular Degeneration, one report showed that 3 partially blind women became blind after the treatment with stem cells and the other report showed that an inevitable loss of vision was halted by use of stem cells in another patient. The stem cells used in these two reports were from two different sources fat and skin cells.

First of all, we need to remember or understand that Macular Degeneration is caused by the deterioration of the central portion of the retina, known as the macula, and it is responsible for focusing central vision in the eye, and it controls our ability to read, drive a car, recognize faces or colors, and see objects in fine detail. In America, it affects more than 10 million people more than cataracts and glaucoma combined.

Caucasians are more likely to develop the disease than African-Americans, Hispanics/Latinos or Africans. At present, Macular Degeneration is considered an incurable eye disease, and the closest hope for cure seems to be via Stem Cell Therapy. As shown in the reports, there is still a lot to be understood about stem cells in terms of dosing, frequency, source to be used for different disorders, etc; especially when talking about very sensitive organs of the body like the eyes.

The Florida Company that treated the three patients that went from partial blindness to total blindness have treated over 7,000 patients and have had very few adverse events reported. The scientific director of the company believes the safety track record is very strong and feels very confident about the procedures that they do as it has shown great success in many different health problems.

However, the rarity of the procedure causing harm draws me to see the many benefits and potential Adult Stem Cell Therapy could have on people. Examples of its effectiveness has been seen in so many patients in different studies and even in my own practice in the United States of America. There are already beneficiaries of Adult Stem Cell Therapy in Nigeria. I can say that my experience using stem cells have been great.

In fact, of all the patients that I have treated, only one did not respond positively after just 1 treatment. This was not even done with Adult Stem Cell Therapy but Platelet Rich Plasma (PRP) Therapy using the patients own blood. Nevertheless, there was no adverse event. The patient is recommended to do Adult Stem Cell Therapy which will increase his chance of success. Many of the other patients showed improvements after the first treatment, and the few that needed second treatment went on to see amazing results after more treatment was done; needless to say that they were elated with the results.

Generally, Adult Stem Cell Therapy and Platelet Rich Plasma Therapy are safe as shown by many published research reports and clinical trials done already. However, this does not guarantee that adverse effects cant occur as seen in the case of the 3 women who had accelerated blindness 2 years ago (as with any other treatments in the scope of medicine).

Another recent report in March 2017 from Medical College of Georgia at Augusta University in USA highlighted one of the benefits of Adult Stem Cell Therapy in stroke patients. The multicenter trial shows that not only was it safe, but if Adult Stem Cell Therapy is given within two days of an ischemic stroke, it could reduce the death of cells around the strokes core that were also injured. The Nigerian government should get involved more and invest more in Regenerative Medicine as it will help improve the health status of the nation.
