Heart Healthy Physical Activity

February 7, 2017 Teresa Stockton - Aging, Blog, Sports and Fitness

The heart is often used as a symbol of vitality for good reasons. The heart pushes blood and oxygen to every cell in the body to be used as fuel and carries waste away. Without this process, the body cannot function. The heart plays a role in many aspects of your health and wellness.

Efficiency Matters
The heart beats an average of 60-80 beats per minute, which can add up to millions of beats in just one month. When something works this hard, it is important that it also works efficiently. Well-conditioned athletes can have resting heart rates below 50 beats/minute. Even though their heart beats slower, it can do the same amount of work or more than a heart that beats 60-80 beats/minute. An athlete’s heart pumps stronger during each beat, needing fewer beats to get the job done. Over a lifetime, a difference of 10-30 beats/minute can add up to quite a few beats.

An Ounce of Prevention…
The heart can be affected by physical and mental stressors. You can feel your heart speed up when you sprint across a busy road or when you have a burst of emotion like anger or surprise.

Physical activity can decrease the effect of stress on the heart and body. A fit body and mind will help improve heart health. Regular physical activity can:

Improve physical abilities by:
• Improving the heart’s ability to pump blood
• Increasing energy levels
• Increasing muscle strength and endurance
• Improving agility

Change physical appearance by:
• Toning your muscles which gives you a tighter appearance
• Burning calories which helps with weight loss or maintenance

Improve overall wellness by:
• Helping with stress management
• Improving self-image
• Helping to decrease anxiety and depression
• Improving relaxation
• Improving the ability to sleep
• Creating a social activity opportunity
• Promoting healthier cholesterol levels

If you have heart problems, physical activity can still play an important role. A strong and healthy body can help you manage your condition. Physical activity can help reduce the stress on a sick or weak heart and decrease secondary risks like obesity and diabetes. If you do have heart health issues, talk to your doctor before starting an exercise program.

Even if you are healthy, but have not exercised in a long time, you may need to talk to your doctor to make sure that you are in good physical condition to exercise.

Where to Start
For most people, you can begin right away. Find an activity program that you enjoy. Do not pick an activity that does not fit into your schedule, does not fit in with your personal preferences, or has too many obstacles, because you may lose interest quickly. A program that starts with too much intensity is also likely to lose your interest.

Work towards reaching these basic goals:
• 30-60 minutes of physical activity on most days of the week (total of at least 150 minutes/week)
• Include some strength activities at least 2 times/week

Make It Stick
Long-term regular physical activity will count more than a brief and spectacular burst of activity. Most people do not plan to become sedentary. It creeps up on you. Work to increase your physical activity the same way. Gradually add steps. Find activities you enjoy that can replace more sedentary activities.

Here are more tips that have been shown to be useful:
• Find an exercise partner. You are less likely to skip the activity if someone is waiting for you.
• Write it down or use a fitness tracker. Keep a log of your activities and how much you accomplished either by distance or time. It will help keep you honest.
• A long-term goal is fine, but also make short-term goals, because they provide quicker feedback.
• This is important, make it a priority. Plan it out. Find a time in your daily routine when you can regularly fit the activity in.
• Consider doing your activity in 10-minute spurts throughout the day. Spurts can be as effective as being active for 30 minutes straight.
• Be flexible. Life happens and you may find that you need to make adjustments to your routine. A rigid schedule and goal may not be worth the stress. Keep an open mind to new activities and schedules.

Make It Count
Any physical activity is better than none. But at least a few days per week you should aim for more than a leisurely stroll. A moderate intensity level is best to help you make health changes. Moderate intensity activity is enough to get your heart rate up and make you feel a little out of breath but not feel worn out when you are done.

Do not forget to enjoy your activity for the daily benefits it can bring and know that your heart appreciates it as well!

Winter Safety Tips for Children

January 3, 2017 Teresa Stockton - Blog, Pediatrics

When the temperature drops and snow is on the ground, your children can still benefit from some outdoor physical activity. All it takes is a little extra planning to stay safe.

Layer Up!
Infants and children lose heat more quickly due to their size. As a result, they are more likely to suffer from low body temperature, also known as hypothermia. Dressing in layers is a good way to provide your child with added warmth during the winter months. Your child should wear 1 more layer than an adult would wear. Choose fabrics that wick moisture to help pull sweat away from your child’s skin and keep them warm.

Here are some other winter stafety tips to help keep your child safe in the cold:
• Mittens are warmer, but gloves allow your child to use their fingers more. Consider having your child wear mittens over a pair of light gloves.
• Keep your child’s feet warm and dry with 2 pairs of socks.
• Avoid long scarves and drawstrings or ties, which could become a choking hazard. Consider neck warmers or turtleneck garments.
• Choose hats and hoods that do not obstruct your child’s vision.
• Keep a dry set of clothing at school in the event your child’s clothes become wet.

Winter Sport Safety
Winter safety tips for sports such as skiing, skating, snowboarding, and sledding require adult supervision and added safety measures. To help keep your child safe:
• Make sure your child wears a helmet and other protective gear such as wrist guards for snowboarding and a mouth guard for ice hockey.
• Teach your child to be aware of and avoid hazards when sledding such as cars, trees, and ponds.
• Do not allow your child to skate on surfaces until you are sure the water is frozen solid.
• Do not allow your child to wear headphones while playing. Headphones will block traffic or grooming machine sounds.
• Encourage your child to keep moving when outdoors to help generate body heat.

Bring your child inside at the first sign of frostnip—skin that is red, numb, and tingly. Soak your child’s skin in warm water until the symptoms go away. Do not rub the skin. If symptoms do not improve, call your child’s doctor. If your child’s skin becomes white, hard, and swollen, your child may have frostbite. The skin may also burn, tingle, or become numb. If you think your child has frostbite, bring your child inside and put your child in dry clothes. Do not rub the skin, rubbing can cause more damage. Call for medical help right away.

Don’t Skip the Sunscreen
It is possible for your child to get a sunburn in the winter since sunlight reflects off of the snow and ice. Your child should use a sunscreen with an SPF of at least 30. Apply it to your child 20 minutes before going outside and reapply it every 2 hours.

Fuel Up for Fun
Dehydration can contribute to hypothermia. Encourage your child to drink plenty of fluids, especially during vigorous physical activities. Your child will also need to fuel up to generate body heat needed for outdoor play. Provide your child with plenty of healthy snacks such as trail mix, fruit and bread.

When to Play
Freezing temperatures and wind are risk factors for hypothermia and frostbite. Avoid severe cold. Keep an eye on weather forecasts and plan outdoor activities for warmer days without snow or rain.

Following these winter safety tips will allow you and your child to safely enjoy the beauty of winter.

Type 2 Diabetes (Diabetes Mellitus Type 2; Insulin-Resistant Diabetes; Diabetes, Type 2)

November 10, 2016 Teresa Stockton - Blog, General Information

Definition
Glucose is a type of sugar. It comes from food, and is also created in the liver. Glucose travels through the body in the blood. It moves from the blood to cells with the help of a hormone called insulin. Once glucose is in those cells, it can be used for energy.

Diabetes is a condition that makes it difficult for the body to use glucose. This causes a buildup of glucose in the blood. It also means the body is not getting enough energy. Type 2 diabetes is one type of diabetes, and it is the most common.

Medication, lifestyle changes, and monitoring can help control blood glucose levels.

Causes
Type 2 diabetes is often caused by a combination of factors. One factor is that your body begins to make less insulin. A second factor is that your body becomes resistant to insulin. This means there is insulin in your body, but your body cannot use it effectively. Insulin resistance is often related to excess body fat.

Risk Factors
Type 2 diabetes is more common in people who are aged 45 years and older. It is also common in younger people who are obese and belong to at-risk ethnic groups. Other factors that increase your chance for type 2 diabetes include:
• Prediabetes — impaired glucose tolerance and impaired fasting glucose
• Metabolic syndrome — a condition marked by elevated cholesterol, blood glucose, blood pressure, and central obesity
• Excess weight or obesity, especially central obesity
• Lack of exercise
• Poor diet — high intake of processed meats, fats, sugar-sweetened foods and beverages, and calories
• Family history of type 2 diabetes
• High blood pressure
• History of cardiovascular disease
• Depression
• History of gestational diabetes, or having a baby that weighs over 9 pounds at birth
• Endocrine disorders, such as Cushing’s syndrome, hyperthyroidism, acromegaly, polycystic ovary syndrome, pheochromocytoma, or glucagonoma
• Conditions associated with insulin resistance, such as acanthosis nigricans
• Certain medications, such as glucocorticoids or thiazides
• Certain ethnic groups, such as African American, Hispanic, Native American, Hispanic American, Asian American, or Pacific Islander

Symptoms
You may have diabetes for years before you have symptoms. Symptoms caused by high blood sugar or include:
• Increased urination
• Extreme thirst
• Hunger
• Fatigue
• Blurry vision
• Irritability
• Frequent or recurring infections
• Poor wound healing
• Numbness or tingling in the hands or feet
• Problems with gums
• Itching
• Problems having an erection

Diagnosis
The doctor will ask about your symptoms and medical history. You will also be asked about your family history. A physical exam will be done.

Diagnosis is based on the results of blood testing. American Diabetes Association (ADA) recommends diagnosis be made if you have one of the following:
• Symptoms of diabetes and a random blood test with a blood sugar level greater than or equal to 200 mg/dL (11.1 mmol/L)
• Fasting blood sugar test is done after you have not eaten for 8 or more hours—showing blood sugar levels greater than or equal to 126 mg/dL (7 mmol/L) on two different days
• Glucose tolerance test measures blood sugar 2 hours after you eat glucose—showing glucose levels greater than or equal to 200 mg/dL (11.1 mmol/L)
• HbA1c level of 6.5% or higher—indicates poor blood sugar control over the past 2-4 months

* mg/dL = milligrams per deciliter of blood; mmol/L = millimole per liter of blood

Treatment
Treatment aims to:
• Maintain blood sugar at levels as close to normal as possible
• Prevent or delay complications
• Control other conditions that you may have, like high blood pressure and high cholesterol

Diet
Food and drinks have a direct effect on your blood glucose level. Eating healthy meals can help you control your blood glucose. It will also help your overall health. Some basic tips include:
• Follow a balanced meal plan. It should include carbohydrates, proteins, and fats.
• Be aware of appropriate serving size. Measure your food to help understand ideal serving size.
• Do not skip meals. Plan your meals and snacks through the day. Having meals throughout the day can help avoid major changes in glucose levels.
• Eat plenty of vegetables and fiber.
• Limit the amount of fat (especially saturated and trans fats) in your foods.
• Eat moderate amounts of protein and low-fat dairy products.
• Carefully limit foods containing high concentrated sugar.
• Keep a record of your food intake. Share the record with your dietitian or doctor. This will help to create an effective meal plan.

Weight Loss
If you are overweight, weight loss will help your body use insulin better. Talk to your doctor about a healthy weight goal. You and your doctor or dietitian can make a safe meal plan for you.

These options may help you lose weight:
• Use a portion control plate
• Use a prepared meal plan
• Eat a Mediterranean-style diet

Exercise
Physical activity can:
• Make the body more sensitive to insulin
• Help you reach and maintain a healthy weight
• Lower the levels of fat in your blood

Aerobic exercise is any activity that increases your heart rate. Resistance training helps build muscle strength. Both types of exercise help to improve long-term glucose control. Regular exercise can also help reduce your risk of heart disease.

Talk to your doctor about an activity plan. Ask about any precautions you may need to take.

Medication
Certain medications will help to manage blood glucose levels.

Medication taken by mouth may include:
• Biguanides reduce the amount of glucose made by the body
• Sulfonylureas encourage the pancreas to make more insulin
• Insulin sensitizers to help the body use insulin better
• Starch blockers to decrease the amount of glucose absorbed into the blood
• Sodium-glucose co-transporter 2 (SGLT-2) inhibitors to increase glucose excretion in urine
• Bile acid binders

Some medications needs to be given by injection, such as:
• Incretin-mimetics stimulate the pancreas to produce insulin and decrease appetite, which can assist with weight loss
• Amylin analogs replace a protein of the pancreas that is low in people with type 2 diabetes

Insulin
Insulin may be needed if:
• The body does not make enough of its own insulin
• Blood glucose levels cannot be controlled with lifestyle changes and medications

Insulin is given through injections. There is one short-acting inhaled insulin which may be available for select persons.

Blood Glucose Testing
You can check the level of glucose in your blood with a blood glucose meter. Checking your blood glucose levels during the day can help you stay on track. It will also help your doctor determine if your treatment is working. Keeping track of blood sugar levels is especially important if you take insulin.

Regular testing may not be needed if your diabetes is under control and you don’t take insulin. Talk with your doctor before stopping blood sugar monitoring.

An HbA1c test may also be done at your doctor’s office. This is a measure of blood glucose control over a long period of time. Doctors advise that most people keep their HbA1c levels below 7%. Your exact goal may be different. Keeping HbA1c in your goal range can help lower the chance of complications.

Counseling
Depression can undermine your recovery and put you at risk for other complications. Feelings of sadness, hopelessness, and loss of interest in your favorite activities that stay with you for at least 2 weeks should prompt you to call your doctor. Depression is treatable. Your doctor may refer you to counseling to help you better manage your depression and diabetes.

Decreasing Risk of Complications
Over a long period of time, high blood glucose levels can damage vital organs. The kidneys, eyes, and nerves are most affected. Diabetes can also increase your risk of heart disease.

Maintaining goal blood glucose levels is the first step to lowering your risk of these complications. Other steps:
• Take good care of your feet. Be on the lookout for any sores or irritated areas. Keep your feet dry and clean.
• Have your eyes checked once a year.
• Don’t smoke. If you do, look for programs or products that can help you quit.
• Keep track of your moods and be alert for persistent depressive symptoms.
• Plan medical visits as recommended.

Prevention
To help reduce your chance of type 2 diabetes:
• Participate in regular physical activity
• Maintain a healthy weight
• Drink alcohol only in moderation (2 drinks per day for a man, and 1 drink per day for a woman)
• Eat a well-balanced diet:
– Get enough fiber
– Avoid fatty foods
– Limit sugar intake
– Eat more green, leafy vegetables
– Eat whole fruits, especially apples, grapes, and blueberries

Bladder Control During Pregnancy

October 18, 2016 Teresa Stockton - Blog, Women's Health

Aside from a growing belly, you may notice other changes in your body now that you are pregnant. One thing you may notice is the loss of urine when you are not trying to urinate. Loss of bladder control, also called incontinence, is common during pregnancy and after childbirth. Needing to run to the bathroom often or leaking urine can make you feel embarrassed. Do not feel shy about asking for physical therapy for incontinence. They can help you understand and manage bladder control, and make sure there are not other conditions causing your incontinence. Here is some information to help you learn more.

HOW DOES THE BLADDER WORK?
Urine is stored in your bladder, which is an organ located in the pelvis. The muscles of the pelvis help keep your bladder in place. When you urinate, urine travels from your bladder and out of your body through a tube called the urethra. Ring-like muscles (sphincter muscles) keep the urethra closed so urine does not pass until you are ready to urinate. Muscles at the end of the urethra (sphincter muscles) and in the pelvic floor also help to hold back urine.

HOW CAN BEING PREGNANT CAUSE BLADDER CONTROL PROBLEMS?
The weight of a baby in your belly and the act of giving birth will put pressure on your bladder and may cause your pelvic muscles to stretch and weaken. This causes your bladder to sag, and your urethra to stretch. Nerves can also be damaged. It is this damage to muscles and nerves that can cause bladder control problems to persist.

HOW CAN I CONTROL MY BLADDER?
The good news is that incontinence may go away once your pelvic muscles heal, usually 6 weeks or so after giving birth. But you can take steps after childbirth to minimize bladder control problems by doing exercises to strengthen your pelvic floor muscles. Kegel exercises are one type of pelvic floor muscle exercise.

Kegel exercises do not require equipment and can be done anywhere—while sitting at your desk, standing in line at the bank, or even lying down in bed. They are done by squeezing your sphincter muscles in the same way you would when stopping urine flow. After 6-8 weeks of doing the exercises, you may find that you have fewer leaks.

Talk to your doctor to learn more about how to correctly do Kegel exercises. Following pregnancy, if Kegel exercises do not control the incontinence, your doctor may discuss other treatments or refer you to a specialist who can help.

Here are some general steps for doing Kegel exercises from the American Pregnancy Association:

• Squeeze your pelvic floor muscles as if you were trying to stop the flow of urine. Do not squeeze the muscles in your belly, legs, or buttocks.
• Hold for 5-10 seconds, then relax.
• Repeat 10-20 times.
• Try to do at least 3 sets per day.

If incontinence is still bothersome, talk to your doctor about other options, such as wearing absorbent pads or briefs. With support from your healthcare team, you will be able to manage incontinence, as well as other bodily changes that come with pregnancy.

Exercise and Bone Health

September 1, 2016 Teresa Stockton - Aging, Blog, Sports and Fitness

Bone is living tissue that is constantly undergoing a process called remodeling. In remodeling, cells called osteoclasts are breaking down old bone, as cells called osteoblasts are replacing it with new tissue. Many factors can affect the remodeling process and leave you with bones that are less dense and more fragile.

Some factors that interfere with bone health and remodeling are:
• Increased age
• Low vitamin D—The body makes vitamin D in response to sunlight. You can also get vitamin D by eating certain kinds of food or by taking a supplement.
• A diet low in calcium
• Smoking
• Lack of exercise—especially weight bearing and resistance exercise

Why Exercise Is Good for Bone Health
Regular weight-bearing and resistance exercise helps build muscle, as well as maintain and increase bone strength. Exercise causes the muscle to contract against the bone. This action stresses or stimulates the bone, and the bone becomes stronger and denser. The 3 main types of exercise are (some activities can be more than 1 type):

Aerobic (Cardiovascular) Exercises to Improve Bone Health
In aerobic exercise, you continually move large muscles in the legs, shoulders, and buttocks. This action causes you to breathe more deeply, and your heart to work harder pumping blood, thereby strengthening your heart and lungs. Examples include:
• Walking
• Jogging
• Running
• Aerobic dance
• Bicycling
• Swimming

Weight-Bearing Exercises to Improve Bone Health
In weight-bearing exercises, your bones and muscles work against gravity, and your feet and legs bear the weight. Your bones adapt to the weight and pull of the muscle during weight-bearing exercise. Examples of weight-bearing exercises include:
• Jogging
• Walking
• Stair climbing
• Dancing
• Soccer

Resistance Exercises to Improve Bone Health (Strength Training)
Resistance exercises use muscle strength to improve muscle mass and strengthen bone. Examples include:
• Weight lifting, using:
• Free weights
• Weight machines
• Elastic tubing

• Calisthenics such as push-ups and chin-ups

Tips for Beginning:
Aerobic or Weight-bearing Exercises to Improve Bone Health
• Warm up for 5 minutes before activity. This can consist of dynamic stretches that involve movement and a light walk.
• Start the activity slowly for the first 5 minutes.
• Slowly increase your intensity so that your heart rate increases. A person doing moderate-intensity aerobic activity can talk. A person doing vigorous-intensity activity cannot say more than a few words without stopping to take a breath.
• Gradually increase your workout until you are working out at least 150 minutes a week at moderate–intensity or 75 minutes a week at vigorous intensity.

Resistance Exercises to Improve Bone Health
• Begin each exercise with light weights and minimal repetitions.
• Slowly (over weeks) increase weight, never adding more than 10% in a given workout.
• Do these exercises 2-3 times a week. Allow for 1 day between each workout for your bones and muscles to rest and repair themselves.
• Gradually increase the number of repetitions to 2-3 sets of 8-10 repetitions with a rest period of 30-60 seconds between sets.
• Although stiffness the day after exercise is normal, if you are in pain, you did too much. Decrease the intensity or the duration of your exercise.

Before starting any type of exercise program, check with your doctor about any possible medical problems you may have that could limit your ability to exercise.

Juvenile Rheumatoid Arthritis

July 19, 2016 Teresa Stockton - Blog, Pediatrics

Definition

Juvenile rheumatoid arthritis (JRA), also known as juvenile idiopathic arthritis, is a disease of the joints in children. It can affect a child over a long period of time. JRA often starts before the child is 16 years old.

In Juvenile rheumatoid arthritis, the joint becomes swollen. It will make the joint painful and difficult to move. JRA can also lead to long term damage to the joint. For some, JRA can interfere with the child’s growth and development.

There are 5 major types of juvenile rheumatoid arthritis:
• Pauciarticular JRA—4 or less joints are affected in the first 6 months of illness
• Polyarticular JRA—5 or more joints are affected in the first 6 months of illness
• Enthesitis associated arthritis—swelling of the tendon at the bone
• Psoriatic arthritis—associated with a skin disease called psoriasis
• Systemic onset JRA (also called Stills disease)—affects the entire body, least common type of JRA

Causes

Juvenile rheumatoid arthritis is caused by a problem of the immune system. The normal job of the immune system is to find and destroy items that should not be in the body, like viruses. With JRA, the immune system attacks the healthy tissue in the joint. It is not clear why this happens. The immune system problems may be caused by genetics and/or factors in the environment.

People of Hispanic American, Asian American, Pacific Islander, Native American, or African American descent are at higher risk.
Having prediabetes means that you are at high risk for developing diabetes and may already be experiencing adverse effects of elevated blood sugar levels.

Risk Factors

Girls are more likely to get JRA than boys.

There are no clear risk factors for JRA. Factors that may be associated with some types of JRA include:
• Family history of:
• Anterior uveitis with eye pain
• Inflammatory back arthritis (ankylosing spondylitis)
• Inflammatory bowel disease

Symptoms

• Symptoms may include:
• Joint stiffness, especially in the morning or after periods of rest
• Pain, swelling, tenderness, or weakness in the joints
• Fever
• Weight loss
• Fatigue or irritability
• Swelling in the eye—especially associated with eye pain, redness, or sensitivity to light
• Swollen lymph nodes
• Growth problems, such as:
• Growth that is too fast or too slow in one joint (may cause one leg or arm to be longer than the other)
• Joints grow unevenly, off to one side
• Overall growth may be slowed

Some symptoms are specific to each type of juvenile rheumatoid arthritis . For example:
• Symptoms common with pauciarticular JRA include:
• Problems most often found in large joints. These joints include knees, ankles, wrists, and elbows.
• If the left-side joint is affected, then the right-side similar joint will not be affected. For example, if the right knee is affected, then the left knee will be healthy.
• May also have swelling and pain at on the tendons and ligaments attached to the bone

• Symptoms common with polyarticular JRA include:
• Problems found most often in small joints of the fingers and hands. May also affect weight-bearing joints like the knees, hips, ankles, and feet.
• Joints on both sides of the body are affected. For example, if the left hand is affected, then the right hand will also be affected.
• May also have a blood disorder called anemia. This is an abnormally low number of red blood cells.
• One type of polyarticular JRA may occur with:
• A low-grade fever
• Nodules—bumps on parts of body that receive a lot of pressure such as elbows

• Symptoms common with systemic onset JRA include:
• Some of the first signs may be a high fever, chills, and a rash on the thighs and chest. May appear on and off for weeks or months
• May have swelling in the heart, lungs, and surrounding tissues
• The lymph nodes, liver and/or spleen may become enlarged
• Children with enthesitis arthritis often have tenderness over the joint where the pelvis and spine meet.
• Children with psoriatic arthritis often have finger or toe swelling. There may also be damage on fingernails.

Often, there are remissions and flare-ups. Remission is a time when the symptoms improve or disappear. Flare-ups are times when symptoms become worse.

Diagnosis

You will be asked about your child’s symptoms. You will also be asked about your family medical history. A physical exam will be done. An eye examination may also be done to check for swelling in the eye. Your child may be referred to a specialist if JRA is suspected. The specialist is a doctor that focuses on diseases of the joints.

Images may be taken of your child’s bodily structures. This can be done with x-rays.

Your child’s bodily fluids may be tested. This can be done with:
• Blood tests
• Urine tests
• Tests of joint fluid

Treatment

Talk with your doctor about the best plan for your child. The plan will work to control swelling, relieve pain, and control joint damage. The goal is to keep a high level of physical and social function. This will help keep a good quality of life. Treatment options include the following:

Medication

There are several types of medication that may be used:

• Nonsteroidal anti-inflammatory drugs (NSAIDs)—to help swelling and pain
• Disease-modifying antirheumatic drugs (DMARDs)—to slow the progression of the disease
• Tumor necrosis factor (TNF) blockers—to decrease swelling, pain, and joint stiffness
• Interleukin inhibitors—to reduces disease activity
• Corticosteroids through IV or by mouth—for swelling
• Steroid injections into the joint—may help relieve swelling and pain in some children

Polyarticular JRA may become inactive in children who begin medications within 2 years of onset.

Physical Therapy

Exercise is done to strengthen muscles and to help manage pain. Strong nearby muscles will support the joint. It also helps to recover the range of motion of the joints. Normal daily activities are encouraged. Non-contact sports and recreational activities may be good options. Physical activities can also help boost a child’s confidence in their physical abilities.

Physical therapy may be needed. This will help to make the muscles strong and keep the joints moving well.

Maintenance Devices

Splints and other devices may be recommended. They may be worn to keep bone and joint growth normal. Some joints may get stuck in a bent position. These devices can help prevent this.

Prevention

There is no known way to prevent JRA.

What Does It Really Mean to Have Prediabetes?

June 9, 2016 Teresa Stockton - Blog, General Information

Type 2 diabetes usually occurs as a result of genetics and lifestyle. It is marked by abnormally high levels of blood sugar, known as glucose. Glucose is the primary source of energy for our cells that the body makes from food we ingest. The onset of type 2 diabetes is triggered when the body is no longer able to properly use insulin, the hormone that helps cells take in glucose from the blood. When glucose stays in the blood stream instead of moving into the cells, nerves and blood vessels can be damaged. This increases the risk of cardiovascular disease, stroke, blindness, kidney disease, and circulation problems.

What Is Prediabetes?
Prediabetes is a condition that precedes the onset of type 2 diabetes. It is characterized by blood glucose levels that are elevated, though not high enough to be classified as diabetes. Doctors usually refer to prediabetes as impaired glucose tolerance or impaired fasting glucose. The American Diabetes Association (ADA) recommends screening for all adults 45 years old and older. Also, if you are younger than 45 and are overweight or obese and have risk factors for diabetes, you should be screened. Risk factors include:
• Family history of diabetes
• Having hypertension, high cholesterol, or high triglycerides
• Sedentary lifestyle
• History of gestational diabetes or giving birth to a baby weighing more than 9 pounds (4 kilograms)
• History of cardiovascular disease
• Having a condition associated with insulin resistance, such as polycystic ovary syndrome or metabolic syndrome

How Do You Know If You Have Prediabetes?
During a routine office visit, your doctor can order tests, such as:
• Fasting plasma glucose test—For this test, you fast overnight and have your blood glucose measured in the morning before eating. Results in the range of 100-125 mg/dL (5.6-6.9 mmol/L) may indicate prediabetes.
• Oral glucose tolerance test (OGTT)—Again, you fast overnight and have your blood glucose measured after the fast. Then, you consume a sugary drink and have your blood glucose measured two hours later. Results in the range of 140-199 mg/dL (7.8-11 mmol/L) indicate prediabetes.
• Hemoglobin A1c (HbA1c)—This is an indicator of your average blood sugar levels over the previous three months. Results in the range of 5.7%-6.4% indicate prediabetes.

What Can You Do If You Have Prediabetes?
If you are diagnosed with prediabetes, it is important to take action to manage your condition. If you are overweight, your doctor may recommend that you lose weight. Reducing your body weight, even by 5%-10% can help improve your health. In general, changing your diet and being physically active and exercising at least 30 minutes a day will help you stay on track. Participating in a behavioral modification program may further help you achieve your weight loss goals.

Because many of the lifestyle-related risk factors associated with diabetes are also risk factors for other health issues, making lifestyle changes to reduce your risk of diabetes may have a positive effect on your overall health.

Some people can take medication to manage their blood glucose levels, though lifestyle modification should be the first approach to manage prediabetes. Medications that may be used include metformin, pioglitazone, and acarbose.

How Can You Prevent Prediabetes?
The same strategies that are used to lower your risk of type 2 diabetes can be applied to prediabetes, as well. The American Diabetes Association (ADA) recommends these strategies:
• Lose excess weight.
• Exercise for at least 150 minutes per week.
• Reduce your intake of calories and fat.
• Try to eat more fiber and whole grains.

If you do have prediabetes, you can take steps that may slow or avoid the progression to type 2 diabetes. It will take a lot of effort on your part, but the potential benefits—being healthy and living longer—are worth it.

Exercise May Reduce Risk of Low Back Pain

May 12, 2016 Teresa Stockton - Back, Blog

Low back pain is a common complaint that can last a few days or weeks or become a chronic condition with significant impact on well being. Treatments can vary depending on the cause.Chronic back pain can be difficult to successfully treat and it may take some time to find what treatment works best for each person. Since treatment is not guaranteed to work, prevention is the best option. Back pain is often the result of long term stress on the back such as poor posture, sedentary behavior, or regular strain on the back. Prevention will likely involve a number of different steps to reduce these stresses. However, existing studies have not found clear recommendations for the best methods to go about it.

Researchers wanted to investigate the effectiveness of a number of interventions for the prevention of low back pain. The study, published in JAMA Internal Medicine, found that exercise alone or in combination with education was most effective for preventing low back pain.

About the Study
The systematic review of 21 randomized controlled trials included 30,850 men and women without low back pain. The participants were randomized to 6 different prevention strategies, including exercise, education, exercise plus education, back belt, and shoe insoles. The control groups received no intervention, minimal interventions, or placebo.

When compared to the control group exercise was associated with:
• Fewer low back pain episodes in the first 12 months (in 4 trials with 898 people)
• Fewer sick days due to back pain in follow up 12 months or longer (in 2 trials with 128 people)
• Reduction in short-term (4 trials with 422 people) and long-term low-back pain episodes (2 trials with 138 people) when combined with education

Education alone, back belts, and shoe insoles did not appear to have any benefit during the trials.

How Does This Affect You?
A systematic review combines the results of several smaller studies to arrive at one result. The benefit of this type of review is that it increases the number of participants which increase reliability of results. However the review is only as reliable as the studies that are included and the method used to combine the results. There were some flaws in every trial that were included in this analysis. For example, many of the included trials had a high dropout rate during the trial which decreases the reliability of their results.

Low back pain is often associated with an imbalance or weakness of certain back muscles. An exercise program will improve your physical fitness, strengthen your back muscles, and help you maintain a healthy weight. Regular physical activity may also help maintain a healthy weight which can also put strain on your back. Choose exercises or activities that you enjoy and will make a regular part of your day. For most people, this could include 30 minutes of moderate aerobic exercise per day.
