MRSA Infections

mrsa infection anatomy

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in biomechanics to avoid injuries. I read « Sport Medicine Media Guide » and I learned some good stuff.

Methicillin-Resistant Staphylococcus aureus (S. Aureaus), or MRSA, is a bacterium that creates skin infections and other types of infections. The first time that MRSA was seen in US hospitals during the 1970s. Recently, there is a new strain of MRSA know as Community Acquired Methicillin-Resistant Staphylococcus aureus, or CA-MRSA, has left hospitals and began to spread in the community.

This is the strain that is prevalent among athletes. The difference between CA-MRSA and Healthcare-Associated MRSA (HA-MRSA) is in their effects. CA-MRSA usually creates skin infections while HA-MRSA causes bloodstream, urinary tract and surgical site infections. This make CA-MRSA less dangerous than HA-MRSA. Another difference is that CA-MRSA is more vulnerable to antimicrobial.

Symptoms

Signs of infections are :

  • Redness

  • Warmth, Swelling

  • Pus

  • Pain at sites where there are skin wounds

  • Abrasions or cuts

MRSA has the ability to spread to other organs in the body and when that happens, symptoms are more severe.

At this stage, symptoms are :

  • Fever

  • Chills

  • Low blood pressure

  • Joint pain

  • Severe headaches

  • Shortness of breath

  • An extensive rash over the body

These more advanced systemic symptoms require immediate medical attention.

Treatment

The 1st choice for treating MRSA skin infection is to use an antibiotic that has been created to kill bacteria with mild side effects. Most early infections with no widespread symptoms can be treated with oral antibiotics. Because of the nature of this decease and antibiotic options, many patients think they’re « cured » after only a few doses and decide by themselves to stop taking the prescribed drugs. However, MRSA is able to re-infect the patient and become resistant to antibiotics used previously.

For moderate to severe infections, treatment may be with intravenous antibiotics.

These infections associated with deep abscesses or boils require open surgical drainage in addition to antibiotic therapy. Most infections resolve in 7-10 days with an adequate treatment despite the fact that a deep abscess can take up to 4 weeks to eradicate the infection by resolving the abscess cavity.

Early identification and treatment of MRSA infections decrease the amount of playing time lost and decrease the chance that the infection will become severe. Skin may be protected by protective clothing or gear designed to prevent skin abrasions or cuts.

Prevention

It’s necessary that athletes have good personal hygiene but it must be added that athletes and visitors to athletes facilities must also keep their hands clean by washing them often with soap and water or using an alcohol-based hand rub. The minimum is to have clean hands before and after sports and activities. For example when we use weight training equipment that is shared by all gym members, it’s important to have clean hands after using toilette or when someone is injured taking care the wounds (including changing bandage).

Ordinary and antimicrobial soaps are effective for washing hands. It’s noted that liquid soap is a better option because it’s not possible to share this type of soap compared to bar soap. Alcohol-based hand sanitizer that contain at least 60% alcohol are the perfect choice.

Athletes should shower immediately after exercise and shouldn’t share soap and towels. Washing all uniforms and clothes after each use is important. Athlete should avoid sharing items that are in contact with the skin and avoid sharing personal items as they contact the skin. Fortunately, most surfaces don’t provoke a risk of spreading staph and MRSA.

Athletes who have had MRSA

Several high school, college and professional athletes have contracted MRSA infections. There have already been epidemics among athletes on the same team. A study published in « The New England Journal of Medicine » shows an infection MRSA among St. Louis Rams professional football franchise (USA) athletes. During a single season, MRSA infections were found among 5 of 58 Rams athletes (9 percents) that was tested. All infections developed on areas of the body that are common places for turf injury.

Stats

  • Today, MRSA accounts for about 50-70% of the S. Aureus infections that are present in healthcare facilities across the world.

  • Statistics fro the Kaiser foundation in 2007 indicated that approximately 1.2 million hospitalized patients contract MRSA infections.

  • Serious MRSA infection is still predominantly related to exposure in the healthcare setting, where approximately 85 percent of all serious MRSA infections occur.

  • Fortunately, in children under 18 years old, mortality rates are much lower (1%), even though the number of hospitalized children with MRSA has almost tripled since 2002.

What Is Motivation

I read a Nerd Fitness article  and there is good stuff.

A guy named Roger Bannister in 1964, Oxford, England, did something impossible. He ran 1.6km (1 mile) in 3 minutes and 59 seconds. While 9 years, the world record was 4 minutes and 01 secondes. 3 years after Roger Bannister’s record, 13 persons ran 1.6km (1 mile) in less than 4 minutes.

It’s like the Tony Hawk’s record with the 900° on a half-pipe. Since 9 persons did it .

How is possible than suddenly abilities improves ? It’s because of equipment or we impose ourselves limits ?

Brain VS muscle

The truth is that you’re physically able to go beyond the limites that your brain tells you.

Look, in 2012, a group of trained cyclists did a 4k timed trial as fast as possible. Their guideline was « Use all efforts ».

They did this trial again with a virtual avatar who had the same speed than them at the first trial. The average speed of all cyclists was 1 % better than the first trial. Remember at the first trial, cyclists were in mode « Use all efforts ».

They did this trial a third time with a virtual avatar again. Cyclists didn’t know that the virtual avatar was a little bit faster than them. Again, cyclists beat the virtual avatar by increasing their performance of 1.7 %.

It’s like to play to Mario Kart and do a race against the ghost of your last performance. You know exactly how to increase the speed and you have a visual cue.

For more information, read the Mark McClusky’s « Faster, Higher, Stronger » about limitations, fatigue, emotions and what our bodies are capable of doing.

Tim Noakes, South Africa professor of exercices and sport science at the University of Cape Town, make the hypothesis that it’s not our body that slow down but our brain who control WHY and HOW our body slow down.

« Fatigue is an emotion, a construct in the mind that helps ensure that exercise is performed within the body’s ability. That emotion is affected by many factors, such as motivation, anger, fear, memories of past performance, self-belief, and what the body is telling the brain….our physical performance is regulated by the brain, not limited by our hearts, lungs, or muscles ».

We’re able to do more than we think. Cyclists always beat the virtual avatar who was faster than them.

How

Read a funny quote on Imgur :

« Better to cultivate discipline than to rely on motivation. force yourself to do things. force yourself to get up out of bed and practice. Force yourself to work. Motivation is fleeting and it’s easy to rely on because it requires no concentrated effort to get. Motivation comes to you, and you don’t have to chase after it.

Discipline is reliable, motivation is fleeting. The question isn’t how to keep yourself motivated. It’s how to train yourself to work without it ».

If you want to be motivated to train, stop it and stop crying. It’s better to build a system that isn’t relied on motivation. Create a system like the cyclists virtual avatar, create an avatar of your last week performances. Don’t be relied on inspiration but build a system for success, a system that improve your abilities each week.

Sometimes, we need people to push us, challenge us to do things we don’t want to do to go to the next level.

Surround yourself with people better than you in your activites. More you do activities with people who have more experience than you, more you become better.

And sometimes, you need a technological assistance to buid these habits :

  • Self-Control to block time-wasting website on our computer

  • Rescue time to track our efficiency

  • Alarm clocks across the room

Did you see ? No ones of these exemples are relied on a motivation, will or be better than someone else. It’s external forces that we use to exceed our limits.

Outworked

Imagine what you can accomplish if failure isn’t an option. McClusky make a theory in his book « the winner is the athlete for whom defeat is the least acceptable rationalization ». So people who want to do everything to achieve their goals almost always accomplish theirs goals.

Watch this Will Smith’s video .

« The only thing that I see that is distinctly different about me is I’m not afraid to die on a treadmill. I will not be out-worked, period. You might have more talent than me, you might be smarter than me, you might be sexier than me, you might be all of those things you got it on me in nine categories.

But if we get on the treadmill together, there’s two things: You’re getting off first, or I’m going to die. It’s really that simple, right ? »

This is why Will Smith is one of the most successful actors.

Of times in our quest when we don’t make sacrifice to succeed, we fall into the belief that accomplishing our goal isn’t possible.

In fact, this rationalisation may appear to several people event before trying !

Instead of rebuking yourself when you aren’t motivated to do exercice or that you struggle to eat healthy, take a step back and look it with a different angle :

  • « how can you build a habit of success and be focus on rather than seeking a motivation to realize it ? »

It’s easy to become ensnared (to chase motivation and fail) or to rationalize inaction and never try. We all fell into the trap.

What is you plan to avoid this trap ?
