Bears continue to mix and match on O-line with Kyle Long limited … – Chicago Sun-Times

With Prospect High School as their setting, the Bears continued to prepare themselves for a future without guard Kyle Long.

Long returned to practice Thursday but didnt participate after undergoing treatment on his surgically repaired right ankle a day earlier.

Coach John Fox said Long met with the doctor who originally performed his surgery in December in Charlotte, North Carolina.

It was pretty convenient, Fox said. We actually planned it about a week ago. Its just timed that way. I thought it went well. And we held him back today. The treatment they did usually requires 24 hours off, but he feels a lot better. Were excited to get him going again.

Fox didnt specify which treatment Long underwent, but platelet-rich plasma (PRP) injections, which promote healing, can require a downtime of 24 hours.

With Long out, Hroniss Grasu practiced at center with the first-team offense, and Cody Whitehair was at left guard.

Its a look the Bears experimented with in Bourbonnais, but it also could be their starting look Saturday in the preseason game against the Cardinals.

There is flexibility that we need in the line, Fox said. Well see how it goes and how we start. We still havent met in really how were going to approach the game as a staff yet.

Another possibility is keeping Whitehair at center and playing Grasu at left guard.

[Grasu is] going to have to know both, Fox said. Hes going to have reps at both.

QB order

The Bears will maintain the same order at quarterback against the Cardinals: starter Mike Glennon, backup Mark Sanchez, then No. 3 Mitch Trubisky.

In and out

Linebackers Danny Trevathan (knee) and Nick Kwiatkoski (concussion) and defensive lineman Akiem Hicks (sore Achilles tendon) participated in practice in various capacities.

Cornerback Prince Amukamara (hamstring), defensive lineman Mitch Unrein (concussion) and nickel back Bryce Callahan (ankle) did not participate.

Study: Implicit hype? Representations of platelet rich plasma in the news media 5 things to know – Becker’s Orthopedic & Spine

After seeing athletes like Tiger Woods, Tom Brady and Kobe Bryant use platelet rich plasma to treat their injuries, consumers have been more motivated to treat their injuries with the same treatment.

However, a recent study by Tim Caulfield, Canada Research Chair, published in PLOS, showed this form of treatment may be exaggerated by the media.

Here are five things to know:

1. In the United States, 87.1 percent of news articles about platelet rich plasma were sports related stories.

2. Of the articles published about platelet rich plasma, 64.8 percent included a brief description of the procedure while 32.5 percent included a detailed description.

3. Approximately 67 percent of articles portrayed platelet rich plasma injections as a routine procedure and 22 percent portrayed the injections as new or cutting edge.

4. In total, 11.7 percent of the articles published described the injections as being experimental.

5. In the end, 23.8 percent of platelet rich plasma injections articles described the treatment as effective.

Sports hype of platelet-rich plasma ‘powerful marketing tool’ but distorts the science – CBC.ca

When injured elite athletes talk aboutusing platelet-rich plasma (PRP), the coverage fuels hype that makes it harder for average consumers to see the limitations of the potential treatment, a new study suggests.

Athletes including American golfer Tiger Woods, NFL quarterback Tom Brady and now-retired NBA playerKobe Bryant have reportedly used the decades-old approach.

When PRP is used in sports medicine circles, theperson's blood is collected and spun to concentrate the platelet component of the fluid, which is then injected back into an injured area, such as a torn tendon.

Tim Caulfield, who holds the Canada Research Chair in health law and policy at the University of Alberta, and his co-authors reviewed newspaper coverage of PRP use between 2009 and 2015in Australia, Canada, Ireland, New Zealand, United Kingdomand the United States. It waspart of their ongoing researchinto what he calls "bunk" or "science hype" exaggeration of the benefits of science and understatement of any risks or other concerns, including instem cell treatments.

"When PRP is covered in the sports pages, it's talked about in a way that if you were just a casual observer of the science, you would assume that this works and that, we think, is a very powerful marketing tool," said Caulfield.

"If you see a story about a pitcher, a football player or track and field star getting PRP and you have an injury and you know of a clinic near you that's offering PRP, I think it does make it seem like it's more legitimate and perhaps that the science is further along than it really is."

In last week's issue of the journal PLOS One, Caulfield and his co-authors reported that a large majority of PRP articles from Australia (97.1 per cent), theU.S. (87.1 per cent)and Canada (79.4 per cent) were sports-related stories.

The exception was in New Zealand, where less than 10 per centwere sports-related. The researchers found that81.8 per centof the articles analyzed were cosmetic stories.

Reality TV star KimKardashianfirst promoted PRPas an anti-aging treatment through thevampire facials she underwenton her show in 2013 to avoid wrinkles.

Caulfieldsaid he sympathizes with sports reporters but he wants the public to recognize how elite athletes are willing to try just about anything, even unproven, because they're desperate to return to play.That doesn't necessarily mean the treatment works.

"To date, the science [for PRP] is far from definitive," he said.

The researchers said their findings raise questions about why there havebeen so few well-conducted, large clinical trials into PRP to truly judge how much it helps or harms.

Dr. Ryan Degen, an orthopedic sports medicine surgeon at Western University in London, Ont., is seeking funding to conduct a clinical trial on PRP.

"The trial that we're going to try to get off the ground is to look at knee arthritis to see if [PRP is]warranted to treat the arthritis or if we should just be sticking with the conventional injections that we've been using," Degen said.

Degen advises athletes to tread cautiously.

Degen tells his patients there are a few possible indicationsto use PRP in sports medicine, but other times, it's not worthwhile, particularly given that the expense can range from $250 to several thousand dollars.

Many people look up to elite and professional athletes.But the study's findings suggest part of the cautionary message around PRP use is lost when athletes are the source of the message, said Dr. Mark Leung, director of the primary care sport and exercise medicine program at theUniversity of Toronto.

For "elite athletes, one of the names of the game is you start to try and compete and win at whatever cost and that may include your health, and so I don't thinkmany individuals [in] the general population may understandthat aspect."

The reality is, PRP injections don't replace an accurate diagnosis and reliable treatments such as exercise, weight management and rehabilitation, Leung said.

"There was some evidence for its use in tennis elbow or in partial tendon tears," said Leung. "I think that evidence is starting to become less clear [on] when to use it and what regimen, because even the way it's been studied has been a bit murky."

For non-elite athletes, Leung suggesteda more moderate approach to diet, workouts and recovery from injuries.

When should you see a podiatric surgeon? – WTOP

This content is sponsored by MedStar Washington Hospital Center

Its Augustthe height of summerand many of us are taking advantage of the longer days to cram in more outdoor activities. For many, it just seems easier, and definitely more enjoyable, to go for an early morning run when its already light outside versus the dark days of winter.

But that increased activity also increases the risk of foot and ankle injuries, particularly among weekend warriors.

Sprains, which can vary widely in severity, are among the most common foot and ankle injuries. For minor problems, time-honored home remedies like icing, elevating, resting the foot and over-the-counter (OTC) anti-inflammatories are often all thats needed. But if you dont notice much relief after a few days of self-care, you should seek a professional opinion from a podiatrist, a doctor who specializes in foot and ankle care.

It may be that you need an ankle brace to support and protect the ligaments that were stretched or torn during the injury. More severe sprains may require a device called a CAM bootbasically a walking cast that relieves the ankle from bearing weight while it heals.

The good news is that most sprained ankles will getter better in a month or two.

Sometimes, however, what first seems like a badly sprained ankle may actually be a broken metatarsalone of the long bones in the middle of the foot. Because the symptoms of a break, especially a Jones Fracture, and a sprain can be so similar, some fractures dont get the early medical attention they may need, including surgery.

Individuals with chronic lateral ankle instability may also benefit from surgery to repair the damaged ligaments and return to a more active lifestyle. The condition is the result of cumulative injuries to the ligaments from frequent sprains, mostly due to overuse. That leaves the ankle more susceptible to chronic swelling, pain, tenderness and weakness, leading to even more sprains in the future.

Another quite common injury is plantar fasciitis, which occurs when you strain the ligament that connects the heel bone to the metatarsals. In 95 to 99 percent of people, it goes away with simple, conservative treatment like stretching, OTC inserts and physical therapy. If such steps dont provide relief, however, Im a big proponent of a promising new treatment called PRP.

PRP, or platelet-rich plasma injections, can often decrease or completely eliminate the pain of plantar fasciitis and other conditions, contributing to a speedier recovery. In the 30-minute procedure, some blood is withdrawn from the patient and then placed in a centrifuge to separate out the platelets, the component that helps with clotting, healing and tissue growth. Then the platelet-rich plasmanow containing three to five times more growth factors than normal is injected into the affected area.

Most patients can get back on their feet within a few days and can resume regular activity within a month.

Feet are the foundation of your fitness. If theyre in pain or stressed, you cant do much of anything. But properly supported, your feet can conquer miles in comfort.

Thats where the right shoes come in to play. And its tricky. Some lucky people are born with a perfectly normal foot; however most of us need some sort of assistance to help achieve the right mechanical balance. For instance, a bunion, flat foot or a really high arch can put extra strain on different tendons and ligaments, leading to arthritis, pain and degeneration.

But finding that sweet spot is a matter of trial and error. Sneakers that I regularly recommend to my patients dont work at all for my wide, highly-arched feet. You need to take time to find that brand and style that is going to be the best fit for your foots particular structure.

Orthotics can also help. I typically recommend that patients first try out an OTC support with a rigid sole, something like a piece of plastic, to see if that helps. In some cases, that may be all the arch support they need, while others may benefit more from a custom-made orthotic. Just be sure to avoid inserts that you can bend in half, which provide cushioning versus support.

The bottom line: Enjoy your summer activities, but dont beat up your feet in the process. And always see a doctor in the event of any significant swelling, bruising or pain.

Background: Stromal vascular fraction (SVF) is a mixture of cells which can be isolated from a mini-lipoaspirate of fat tissue. Platelet-rich plasma (PRP) is a mixture of growth factors and other nutrients which can be obtained from peripheral blood. Adipose-derived stem/stromal cells (ADSCs) can be isolated from fat tissue and expanded in culture. The SVF includes a variety of different cells such as ADSCs, pericytes, endothelial/progenitor cells, and a mix of different growth factors. The adipocytes (fat cells) can be removed via centrifugation. Here, we describe the rationale and, to our knowledge, the first clinical implementation of SVF and PRP followed by repeat dosing of culture-expanded ADSCs into a patient with severe xerostomia postirradiation. Methods: Approximately 120 mLs of adipose tissue was removed via mini-lipoaspirate procedure under local anesthetic. The SVF was prepared from half of the fat and resuspended in PRP. The mixture was delivered via ultrasound directly into the submandibular and parotid glands on both the right and left sides. The remaining 60 mLs of fat was processed to culture-expand ADSCs. The patient received seven follow-up injections of the ADSCs plus PRP at 5, 8, 16, 18, 23, 28, and 31 months postliposuction. The subject was monitored over a period of 31 months for safety (adverse events), glandular size via ultrasound and saliva production. Results: Throughout the 31-month monitoring period, no safety events such as infection or severe adverse events were reported. The patient demonstrated an increase in gland size as measured by ultrasound which corresponded to increased saliva production. Conclusion: Overall, the patient reported improved quality of life and willingness to continue treatments. The strong safety profile and preliminary efficacy results warrant larger studies to determine if this is a feasible treatment plan for patients postradiation.
