QUOTE FOR THE WEEKEND:

“Amyotrophic lateral sclerosis is a fatal type of motor neuron disease. It is characterized by progressive degeneration of nerve cells in the spinal cord and brain. It’s often called Lou Gehrig’s disease, after a famous baseball player who died from the disease. ALS it is one of the most devastating of the disorders that affects the function of nerves and muscles.”

What is Lou Gehrig’s Disease (also called ALS or amyotrophic lateral sclerosis) exactly?

ALS, or amyotrophic lateral sclerosis, is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. A-myo-trophic comes from the Greek language. “A” means no. “Myo” refers to muscle, and “Trophic” means nourishment – “No muscle nourishment.” When a muscle has no nourishment, it “atrophies” or wastes away. “Lateral” identifies the areas in a person’s spinal cord where portions of the nerve cells that signal and control the muscles are located. As this area degenerates it leads to scarring or hardening (“sclerosis”) in the region.

Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their demise. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected, people may lose the ability to speak, eat, move and breathe. The motor nerves that are affected when you have ALS are the motor neurons that provide voluntary movements and muscle control. Examples of voluntary movements are making the effort to reach for a smart phone or step off a curb. These actions are controlled by the muscles in the arms and legs. Motor neurons are nerve cells located in the brain, brain stem, and spinal cord that serve as controlling units and vital communication links between the nervous system and the voluntary muscles of the body. Messages from motor neurons in the brain called upper motor neurons are transmitted to motor neurons in the spinal cord which are lower motor neurons and from them to particular muscles. The problem with ACL, both the upper motor niurons and the ower motor niurons degenerate or die which causes stoppage of sending messages to muscles. Unable to function, the muscles gradually weaken, waste away (atrophy), and have very fine twitches (called fasciculations). Eventually, the ability of the brain to start voluntary movement with messages is unable to work anymore.

Symptoms:

The onset of ALS may be so subtle that the symptoms are overlooked. The earliest symptoms may include fasciculations, cramps, tight and stiff muscles (spasticity), muscle weakness affecting an arm or a leg, slurred and nasal speech, or difficulty chewing or swallowing. These general complaints then develop into more obvious weakness or atrophy that may cause a physician to suspect ALS. Regardless of the part of the body first affected by the disease, muscle weakness and atrophy spread to other parts of the body as the disease progresses.

The parts of the body showing early symptoms of ALS depend on which muscles in the body are affected. Many individuals first see the effects of the disease in a hand or arm as they experience difficulty with simple tasks requiring manual dexterity such as buttoning a shirt, writing, or turning a key in a lock. In other cases, symptoms initially affect one of the legs, and people experience awkwardness when walking or running or they notice that they are tripping or stumbling more often.

There are two different types of ALS, 1 sporadic and 2 familial.

Sporadic which is the most common form of the disease in the U.S., is 90 – 95 percent of all cases. It may affect anyone, anywhere.

Familial ALS (FALS) accounts for 5 to 10 percent of all cases in the U.S. Familial ALS means the disease is inherited. In those families, there is a 50% chance each offspring will inherit the gene mutation and may develop the disease. French neurologist Jean-Martin Charcot discovered the disease in 1869.

Causes of ALS:

The cause of ALS is not known, and scientists do not yet know why ALS strikes some people and not others. An important step toward answering this question was made in 1993 when scientists supported by the National Institute of Neurological Disorders and Stroke (NINDS) discovered that mutations in the gene that produces the SOD1 enzyme were associated with some cases of familial ALS.

ALS usually strikes people between the ages of 40 and 70, and approximately 20,000 Americans can have the disease at any given time (although this number fluctuates). For unknown reasons, military veterans are approximately twice as likely to be diagnosed with the disease than the general public.  Notable individuals who have been diagnosed with ALS include baseball great Lou Gehrig, Hall of Fame pitcher Jim “Catfish” Hunter, Toto bassist Mike Porcaro, Senator Jacob Javits, actor David Niven, “Sesame Street” creator Jon Stone, boxing champion Ezzard Charles, NBA Hall of Fame basketball player George Yardley, golf caddie Bruce Edwards, , musician Lead Belly (Huddie Ledbetter), photographer Eddie Adams, entertainer Dennis Day, jazz musician Charles Mingus, former vice president of the United States Henry A. Wallace, U.S. Army General Maxwell Taylor, and NFL football players Steve Gleason, O.J. Brigance and Tim Shaw.

Who gets ALS?

More than 12,000 people in the U.S. have a definite diagnosis of ALS, for a prevalence of 3.9 cases per 100,000 persons in the U.S. general population, according to a report on data from the National ALS Registry. ALS is one of the most common neuromuscular diseases worldwide, and people of all races and ethnic backgrounds are affected. ALS is more common among white males, non-Hispanics, and persons aged 60–69 years, but younger and older people also can develop the disease. Men are affected more often than women.

In 90 to 95 percent of all ALS cases, the disease occurs apparently at random with no clearly associated risk factors. Individuals with this sporadic form of the disease do not have a family history of ALS, and their family members are not considered to be at increased risk for developing it.

About 5 to 10 percent of all ALS cases are inherited. The familial form of ALS usually results from a pattern of inheritance that requires only one parent to carry the gene responsible for the disease. Mutations in more than a dozen genes have been found to cause familial ALS.

About one-third of all familial cases (and a small percentage of sporadic cases) result from a defect in a gene known as “chromosome 9 open reading frame 72,” or C9orf72. The function of this gene is still unknown. Another 20 percent of familial cases result from mutations in the gene that encodes the enzyme copper-zinc superoxide dismutase 1 (SOD1).

Treatments to this disease:

Recent years have brought a wealth of new scientific understanding regarding the physiology of this disease. There is currently one FDA approved drug, riluzole, that modestly slows the progression of ALS in some people. Although there is not yet a cure or treatment that halts or reverses ALS, scientists have made significant progress in learning more about this disease. In addition, people with ALS may experience a better quality of life in living with the disease by participating in support groups and attending an ALS Association Certified Treatment Center of Excellence or a Recognized Treatment Center. Such Centers provide a national standard of best-practice multidisciplinary care to help manage the symptoms of the disease and assist people living with ALS to maintain as much independence as possible for as long as possible. According to the American Academy of Neurology’s Practice Paramater Update, studies have shown that participation in a multidisciplinary ALS clinic may prolong survival and improve quality of life.

To find a Center near you, visit http://www.alsa.org/community/certified-centers/.

Remember there is no cure yet that has been found for ALS. However, the Food and Drug Administration (FDA) approved the first drug treatment for the disease—riluzole (Rilutek)—in 1995. Riluzole is believed to reduce damage to motor neurons by decreasing the release of glutamate. Clinical trials with ALS patients showed that riluzole prolongs survival by several months, mainly in those with difficulty swallowing. The drug also extends the time before an individual needs ventilation support. Riluzole does not reverse the damage already done to motor neurons, and persons taking the drug must be monitored for liver damage and other possible side effects. However, this first disease-specific therapy offers hope that the progression of ALS may one day be slowed by new medications or combinations of drugs.

The Immune System

 

 

 

 

Immune system. Human anatomy. Human silhouette with internal organs.

We hear those 2 words “Immune System “a lot; what is the immune system?  The main parts of the immune system are:

  • white blood cells.
  • antibodies.
  • complement system.
  • lymphatic system.
  • spleen.
  • bone marrow.
  • thymus.

Your immune system is a large network of organs, white blood cells, proteins (antibodies) and chemicals. This system works together to protect you from foreign invaders (bacteria, viruses, parasites, and fungi) that cause infection, illness and disease.

What does the immune system do and how does it work?

Your immune system works hard to keep you healthy. Its job is to keep germs out of your body, destroy them or limit the extent of their harm if they get in.

When your immune system is working properly: When your immune system is working properly, it can tell which cells are yours and which substances are foreign to your body. It activates, mobilizes, attacks and kills foreign invader germs that can cause you harm. Your immune system learns about germs after you’ve been exposed to them too. Your body develops antibodies to protect you from those specific germs. An example of this concept occurs when you get a vaccine. Your immune system builds up antibodies to foreign cells in the vaccine and will quickly remember these foreign cells and destroy them if you are exposed to them in the future. Sometimes doctors can prescribe antibiotics to help your immune system if you get sick. But antibiotics only kill certain bacteria. They don’t kill viruses.

When your immune system is not working properly: When your immune system can’t mount a winning attack against an invader, a problem, such as an infection, develops. Also, sometimes your immune system mounts an attack when there is no invader or doesn’t stop an attack after the invader has been killed. These activities result in such problems as autoimmune diseases and allergic reactions.

Your immune system is made of up a complex collection of cells and organs. They all work together to protect you from germs and help you get better when you’re sick. The main parts of the immune system are:

  • White blood cells: Serving as an army against harmful bacteria and viruses, white blood cells search for, attack and destroy germs to keep you healthy. White blood cells are a key part of your immune system. There are many white blood cell types in your immune system. Each cell type either circulates in your bloodstream and throughout your body or resides in a particular tissue, waiting to be called into action. Each cell type has a specific mission in your body’s defense system. Each has a different way of recognizing a problem, communicating with other cells on the defense team and performing their function.
  • Lymph nodes: These small glands filter and destroy germs so they can’t spread to other parts of your body and make you sick. They also are part of your body’s lymphatic system. Lymph nodes contain immune cells that analyze the foreign invaders brought into your body. They then activate, replicate and send the specific lymphocytes (white blood cells) to fight off that particular invader. You have hundreds of lymph nodes all over your body, including in your neck, armpits, and groin. Swollen, tender lymph nodes are a clue that your body is fighting an infection.
  • Spleen: Your spleen stores white blood cells that defend your body from foreign invaders. It also filters your blood, destroying old and damaged red blood cells.
  • Tonsils and adenoids: Because they are located in your throat and nasal passage, tonsils and adenoids can trap foreign invaders (for example, bacteria or viruses) as soon as they enter your body. They have immune cells that produce antibodies to protect you from foreign invaders that cause throat and lung infections.
  • Thymus: This small organ in your upper chest beneath your breast bone helps mature a certain type of white blood cell. The specific task of this cell is to learn to recognize and remember an invader so that an attack can be quickly mounted the next time this invader is encountered.
  • Bone marrow: Stem cells in the spongy center of your bones develop into red blood cells, plasma cells and a variety of white blood cells and other types of immune cells. Your bone marrow makes billions of new blood cells every day and releases them into your bloodstream.
  • Skin, mucous membranes and other first-line defenses: Your skin is the first line of defense in preventing and destroying germs before they enter your body. Skin produces oils and secretes other protective immune system cells. Mucous membranes line the respiratory, digestive, urinary and reproductive tracts. These membranes secrete mucus, which lubricates and moistens surfaces. Germs stick to mucus in the respiratory tract and then are moved out of the airways by hair-like structures called cilia. Tiny hairs in your nose catch germs. Enzymes found in sweat, tears, saliva and mucus membranes as well as secretions in the vagina all defend and destroy germs.
  • Stomach and bowel: Stomach acid kills many bacteria soon after they enter your body. You also have beneficial (good) bacteria in your intestines that kill harmful bacteria.

QUOTE FOR THE WEEKEND:

“Menopause is a point in time when you’ve gone 12 consecutive months without a menstrual cycle. The time leading up to menopause is called perimenopause. This is when a lot of women or people assigned female at birth (AFAB) start to transition to menopause. They may notice changes in their menstrual cycles or have symptoms like hot flashes.  Natural menopause is the permanent ending of menstruation that doesn’t happen because of any type of medical treatment. The process is gradual and happens in 3 stages.  The average age of menopause in the United States is approximately 51 years old. However, the transition to menopause usually begins in your mid-40s.  “.

Cleveland Clinic (https://my.clevelandclinic.org/health/diseases/21841-menopause)

Menopause and it’s effects on women’s health.

What is Menopause exactly?

Menopause is when the ovaries naturally stop producing 2 hormones called estrogen and progesterone. Your ovaries are similar to what a car does in that over years it wears down, well so does the mechanism that regulates your hormones which is the ovaries. You go 12 consecutive months without having a period with no reasons to be explained for its occurrence, both biological or physical with it never returning. If both ovaries are removed surgically the menopause kicks in immediately. Menopause has signs and symptoms (s/s) that kick in which have varying intensities (it depends on the individual). You may experience mild to severe s/s.

Menopause is the time that marks the end of your menstrual cycles. It’s diagnosed after you’ve gone 12 months without a menstrual period. Menopause can happen in your 40s or 50s, but the average age is 51 in the United States. Menopause is a natural biological process.

The signs and symptoms of Menopause :

1- Hot Flashes 2-Irregular Periods 3- Breast Pains 4- Night Sweats 5- Mood Swings 6- Loss of Labido 7- Vaginal Dryness 8-Brittle Nails 9-Bloating 10-Irritability 11-Depression 12- Weight Gain 13-Sleep Problems 14- Osteoporosis-one of the worst symptoms of menopause. 15-Loss of breast fullness in some. 16- Thinning of the hair and dry skin.

Did you know over 60% of adult Americans are considered obese or overweight?
Weight gain happens when a person increases their body mass, whether it is a result of fat deposits, additional muscle tissue, or excess fluid. However, weight gain associated with menopause typically involves increased amounts of fat around the abdomen. One of the most accurate ways to see if you are obese is to measure your body mass index which is free online, check out the internet. I do every so often.
Go to Free BMI Calculator – AICR.org‎
www.aicr.org/bmi calculator‎.

On average, a women gains about 12 to 15 pounds between the ages of 45 and 55, this is usually when menopause typically occurs. This extra weight generally does not evenly distribute itself throughout a woman’s body. The weight tends to accumulate around the abdomen instead and women often notice the shape of their bodies slowly losing their hour-glass figure.

What can resolve this issue?

We can’t stop menopause but their are things we can do in dealing with it.

As years progress the metabolism slows down; setting the physiological stage for weight gain. As a woman’s hormones fluctuate prior to menopause and preparing for a permanently reduced hormonal level, it is likely to experience weight gain.

So things that can be done:

Eat well and nutritious foods.

Exercise but balance with rest.

Keep up with regular visits with your doctor for preventive health care and any medical concerns. Continue getting these appointments during and after menopause.

Preventive health care as you age may include recommended health screening tests, such as colonoscopy, mammography and triglyceride screening. Your doctor might recommend other tests and exams, too, including thyroid testing if suggested by your history, and breast and pelvic exams.

QUOTE FOR FRIDAY:

“The aorta carries blood from the heart to the body. Aortic aneurysms can occur anywhere in the aorta. They may be tube shaped or round.

Aortic aneurysms include:

  • Abdominal aortic aneurysm. An abdominal aortic aneurysm occurs along the part of the aorta that passes through the belly area.
  • Thoracic aortic aneurysm. A thoracic aortic aneurysm occurs along the part of the aorta that passes through the chest cavity.”

MAYO CLINIC (https://www.mayoclinic.org/diseases-conditions/aortic-aneurysm/symptoms-causes/syc-20369472)

Some people may have both types of aortic aneurysms.

Having an aortic aneurysm increases the risk of developing a tear in the inner layer of the wall of the aorta. This tear is called an aortic dissection.

Part II Aortic Aneurysms –What’s inside it, What are the risk factors in getting this & the most common causes!

What is inside an aortic aneurysm?

The inside walls of aneurysms are often lined with a blood clot that forms because there is stagnant blood. The wall of an aneurysm is layered, like a piece of plywood.

Who is most likely to have an abdominal aortic aneurysm?

Abdominal aortic aneurysms tend to occur in white males over the age of 60. In the United States, these aneurysms occur in up to 3.0% of the population. Aneurysms start to form at about age 50 and peak at age 80. Women are less likely to have aneurysms than men and African Americans are less likely to have aneurysms than Caucasians.

There is a genetic component that predisposes one to developing an aneurysm; the prevalence in someone who has a first-degree relative with the condition can be as high as 25%.

Collagen vascular diseases that can weaken the tissues of the aortic walls are also associated with aortic aneurysms. These diseases include Marfan and Ehlers-Danlos syndrome.

What are risk factors for aortic aneurysms?

The risk factors for aortic aneurysm are the same as those for atherosclerotic heart disease, stoke, and peripheral artery disease and include:

  • Cigarette smoking: This not only increases the risk of developing an abdominal aortic aneurysm, but also increases the risk of aneurysm rupture. Aortic rupture is a life-threatening event where blood escapes the aorta and the patient can quickly bleed to death.
  • High blood pressure
  • Elevated blood cholesterol levels
  • Diabetes mellitus The most common cause of aortic aneurysms is “hardening of the arteries” called arteriosclerosis. At a majority of aortic aneurysms are from arteriosclerosis. The arteriosclerosis can weaken the aortic wall and the increased pressure of the blood being pumped through the aorta causes weakness of the inner layer of the aortic wall.
  • The aortic wall has three layers, the tunica adventitia, tunica media, and tunica intima. The layers add strength to the aorta as well as elasticity to tolerate changes in blood pressure. Chronically increased blood pressure causes the media layer to break down and leads to the continuous, slow dilation of the aorta.
  • What is the most common cause of aortic aneurysms?

Smoking is a major cause of aortic aneurysm. Studies have shown that the rate of aortic aneurysm has fallen at the same rate as population smoking rates.

Know a aneurysm can be located in different arteries, like the brain with the same common causes, risk factors and make up inside the aneurysm.

“An aortic aneurysm is a balloon-like bulge in the aorta, the large artery that carries blood from the heart through the chest and torso.  Facts about aortic aneurysms:

  • Aortic aneurysms or aortic dissections were the cause of 9,904 deaths in 2019.1
  • In 2019, about 59% of deaths due to aortic aneurysm or aortic dissection happen among men.1
  • A history of smoking accounts for about 75% of all abdominal aortic aneurysms.2
  • The U.S. Preventive Services Task Force recommends that men 65 to 75 years old who have ever smoked should get an ultrasound screening for abdominal aortic aneurysms, even if they have no symptoms.3“.
