Epidemiology

Epidemiology is the process of where one is able to study a disease or disorder. The public health department job is to conduct studies that are epidemiological in nature in order to prevent contagious disease from spreading. An epidemiologist is one who understands the rate/risk ratios, rate/risk differences, and measures the impact on the public.

Each epidemiologist deals in his own science and disciplines when he is taking these factors and measuring them. The discipline requires him to be able to select and use appropriate statistical methods in the analysis of simple data sets and apply these methods by computer using either STATA or EPI-INFO. He must also be able to understand and interpret output from statistical analyses carried out by computer, in relation to research and other questions asked. Then the epidemiologist must present findings based on statistical analysis in a clear concise manner.

The epidemiologist must be able to define a research problem and formulate a study hypothesis and objectives. He must choose an appropriate and ethical study design, plan field procedures, including sample selection, and the design of questionnaires and record forms. A time schedule for the conduct of the study is vital part. The need to prepare a budget is always important for this type of research. A detailed protocol that is of sufficient standard developed into a submission statement for a funding agency.

The epidemiologist must understand the basic statistical measures and concepts underlying the analysis of epidemiological data. He must perform analyses of data arising from epidemiological studies using appropriate computer software. He must be able to identify factors that suggest a disease has an infectious cause. He also must understand the factors determining the spatial, temporal and social distributions of communicable diseases. It is vital that the epidemiologist understand how to measure transmissibility of infections, design, and carry out, analyses, interpret and report an outbreak investigation report. It is of course very vital that the evaluation of vaccine efficacy be investigated.

The study of epidemiology and the use of an epidemiologist are vital for any nation’s health. This is very important for it helps our nation prevent major breakouts of diseases. I would like to say our people do an excellent job in this field and their tasks are not always easy but always necessary. The American Heart Association feels that since heart failure is the number one killer of men and women in America today that our Public Health Department is not fulfilling their duties toward heart related diseases.

In the above description of what epidemiologist, duties are and why we have the study of epidemiology gives a better understanding the medical field problems concerning heart failure patients. The AHA has gathered as much information as possible thru magazines and articles and made a journal for the doctors to refer themselves too. That journal is piece meal at best not complete and not adequate for the care and prevention of heart related problems. That is why we need an epidemiologist from our Public health Department to look at the situation.

Living With Arthritis: 6 Ways to Cope for Arthritis Sufferers

Just because you’ve been diagnosed with arthritis doesn’t mean
that you have to wait in pain for your doctor to contact you.
There are quite a few things you can do as an arthritis sufferer
while waiting for new medications, an appointment for a
specialist or just to work on the problem yourself. This article
will detail some of the simple but highly effective ways you can
manage arthritis comfortably on your own time and at your own
pace.

Living With Arthritis Tip #1: Keep On Moving Although it’s
painful for most arthritis sufferers to stay active, you need to
be mobile every single day in order to keep your current range
of movement. Even if you can only manage a ten minute walk
daily, those ten minutes will do wonders for your mood, joints
and pain in the long term.

Living With Arthritis Tip #2: Don’t Push Yourself If you don’t
have to use your body to move, push or pull something, don’t.
Living with arthritis means taking stock of what you can and
cannot do, and then creating new ways of doing the same thing
without hurting yourself. This might mean purchasing assistive
devices (special can-openers for instance), losing weight or
using the larger joints (such as your hips) instead of the
smaller ones (such as your back) to lift things.

Living With Arthritis Tip #3: Stay Tuned Keep up with the
current findings, research and information related to fellow
arthritis sufferers and the disease itself. As they say, knowing
is half the battle!

Living With Arthritis Tip #4: Talk About It Let your friends and
family know when living with arthritis becomes a challenge, or
when you are frustrated with the disease. Educate them as well,
since the more they know the more they will be able to assist
you as well. Even better, find a local support group where you
can discuss with other arthritis sufferers your feelings about
the illness.

Living With Arthritis Tip #5: If The Shoe Fits… Make sure that
what supports you is actually supporting you properly! Those
suffering from arthritis need even more foot, ankle and joint
support than most. Invest wisely in a pair of orthopedic shoes
and you’ll notice the difference almost immediately.

Living With Arthritis Tip #6: Stretch It Out By stretching the
joints that you use the most, you are not only making your body
work better, you’ll be making your disease easier to manage. Try
to focus on the larger joints (knees, ankles, hips, back) at
least once a day for a cat-like stretch to invigorate the mind,
body and spirit.

Living And Coping With Arthritis – How To Stay Active

Living And Coping With Arthritis – How To Stay Active And Independent
Richard Clement

Arthritis pain can be frustrating.Nagging and crippling
arthritis pain can continue day after day. How much happier
would you be if you could stop your arthritis pain right now and
feel great all day? Knowing the nature of the disease can really
bring you the right answers.

What is arthritis ?

Arthritis comprises over 100 different diseases and conditions.
The word arthritis means “joint inflammation”. When joints are
inflamed, it causes pain and usually also limits movement of the
joints that are affected. For many people, arthritis pain has a
large impact on their life. Arthritis is second only to heart
disease as a cause of work disability. Arthritis limits everyday
activities such as walking, dressing and bathing for more than
16 million Americans. Each year, arthritis results in 750,000
hospitalizations and 36 million outpatient visits. Arthritis is
not just an old person’s disease. Nearly two-thirds of people
with arthritis are younger than 65 years including nearly
300,000 children. Arthritis affects children and people of all
racial and ethnic groups but is more common among women and
older adults. The disease can affect different parts of the
body. Two of the most common forms are osteoarthritis and
rheumatoid arthritis.

Rheumatoid arthritis (RA) is an autoimmune disease in which the
joint lining becomes inflamed as part of the body’s immune
system activity. RA is one of the most serious and disabling
types, affecting mostly women. Rheumatoid arthritis is two to
three times more common in women than in men and generally
strikes between the ages of 20 and 50. Both sides of the body
are usually affected at the same time. Symptoms of RA differ
from person to person but can generally include:

Joint tenderness, warmth, and swelling.

Pain and stiffness lasting for more than 1 hour in the morning
or after a long rest.

Joint inflammation in the wrist and finger joints closest to
the hand .

Fatigue, an occasional fever, and a general sense of not
feeling well . Osteoarthritis (OA) is the most common form of
arthritis. It is a degenerative joint disease in which the
cartilage that covers the ends of bones in the joint
deteriorates, causing pain and loss of movement as bone begins
to rub against bone. OA commonly affects the joints of the
fingers, knees, hips, and spine. Osteoarthritis is more common
in older people because they have been using their joints
longer. Using the joints to do the same task over and over or
simply using them over time can make osteoarthritis worse.
Younger people can also get osteoarthritis. Athletes are at risk
because they use their joints so much. People who have jobs that
require the same movement over and over are also at risk.
Injuries to a joint increase the risk of arthritis in the joint
later on. Excess weight can accelerate arthritis in the knees,
hips and spine. The most common symptom of Osteoarthritis is
pain in the affected joint(s) after repetitive use. Joint pain
is usually worse later in the day. There can be swelling,
warmth, and creaking of the affected joints. Symptoms of OA may
greatly vary. Some patients can be debilitated by their
symptoms. On the other hand, others may have remarkably few
symptoms in spite of dramatic degeneration of the joints
apparent on x-rays. Symptoms also can be intermittent. These 2
forms have very different causes, risk factors, and effects on
the body, yet they often share a common symptom—persistent
joint pain.

What are the causes of arthritis ? Primary OA is mostly
related to aging. With aging, the water content of the cartilage
increases and the protein makeup of cartilage degenerates.
Repetitive use of the joints over the years irritates and
inflames the cartilage, causing joint pain and swelling.
Eventually, cartilage begins to degenerate by flaking or forming
tiny crevasses. Inflammation of the cartilage can also stimulate
new bone outgrowths (spurs) to form around the joints. Sometimes
osteoarthritis follows an injury to a joint. For example, a
young person might hurt his knee badly playing soccer. Then,
years after the knee has apparently healed, he might get
arthritis in his knee joint. RA is an autoimmune disease. This
means the body’s natural immune system does not operate as it
should; it attacks healthy joint tissue, initiating a process of
inflammation and joint damage. RA is a type of chronic arthritis
that occurs in joints on both sides of the body (such as hands,
wrists or knees). This symmetry helps distinguish RA from other
types of arthritis. Rheumatoid arthritis occurs most frequently
in the 30-50 age group, although can start at any age. It is
strongly associated with the HLA marker DR4 – hence Family
history is an important risk factor. The disease affects
Females:Males in a 4:1 ratio. Other conditions can also cause
arthritis. Some include:

Gout, in which crystals build up in the joints. It usually
affects the big toe.

Lupus , in which the body’s defense system can harm the
joints, the heart, the skin, the kidneys, and other organs.

Viral hepatitis ,in which an infection of the liver can cause
arthritis.

What can you do about it ?

Some people may worry that arthritis means they won’t be able to
work or take care of their children and their family. Others
think that you just have to accept things like arthritis. While
there is not yet a cure for arthritis, much can be done today to
reduce pain and boost joint function. Learning how to manage
pain over the long term is essential to maintaining a good
quality of life. There are things you can do to keep the damage
from getting worse. They might also make you feel better.Here
are some simple things to do:

Lose weight if you’re overweight

Exercise regularly for short periods. Going for a walk every
day will help, too.

Use canes and other special devices to protect your joints.

Avoid lifting heavy things.

Don’t pull on objects to move them-push them instead

Use heat or cold to reduce pain or stiffness.

The pain and disability that accompany arthritis can be
decreased through early diagnosis and appropriate management.So
if you have persistent symptoms lasting more than several days –
go see your doctor. The doctor will examine you and may take x
rays (pictures) of your bones or joints to decide if you have
arthritis and what kind you have.

After the doctor knows what kind of arthritis you have, he or
she will talk with you about the best way to treat it. The
doctor may give you a prescription for medicine that will help
with the pain, stiffness, and inflammation. The good news is
that now there is a way to stop your pain with a medication .
Celebrex is a nonsteroidal anti-inflammatory drug (NSAID),
specifically a COX-2 inhibitor, which relieves pain and swelling
(inflammation). It represents a huge breakthrough in the
treatment of pain, inflammation, and stiffness of arthritis.
Celebrex is believed to fight pain and inflammation by
inhibiting the effect of a natural enzyme called COX-2. Unlike
the older medications, however, it does not interfere with a
similar substance, called COX-1, which exerts a protective
effect on the lining of the stomach.Celebrex doesn’t cause the
stomach bleeding and ulcers that traditional nonsteroidal
anti-inflammatory drugs (NSAIDs) might.

What New Therapies for Treatment of Congestive Heart Failure?

Heart disease is one of the deadliest killers in the world to date. Congestive heart failure, a condition found secondary to many major cardiac diseases, possesses its own high mortality rate. Fifty percent of those diagnosed with congestive heart failure will die within the five following years. Scientists and researchers are struggling to understand the exact mechanisms of the disease, and to find a cure.

Congestive heart failure results as the cells in the heart die or become non-functioning due to an event such as a myocardial infarction (a heart attack) or ischemic heart disease. Whatever the cause, the heart is subsequently unable to pump blood adequately throughout the body, resulting in the blood pooling in the organs and fluid building up in and around the lungs as sodium is unable to be properly excreted, causing the dyspnea that is the classic symptom of congestive heart failure.

Clinical research is targeted at both the treatment of the disease and the possibility of repairing the damaged cells in the heart. Current research is underway to test new medications that would assist in vasodilation, as well as a calcium inhibitor that would not result in the higher incidence of cardiac arrhythmia seen with the medications currently on the market.

In the age of natural medicine, the power of the mind has been invoked in clinical trials to use meditation and relaxation techniques to combat the stress on the heart that can be the breaking point for patients with heart failure. Stress has been shown to negatively affect the body’s blood pressure, forcing the heart to work harder and placing an undue amount of pressure on an already weakened muscle. The theory lies in the belief that by learning to maintain a low level of mental stress the heart will be less stressed and therefore less likely to fail completely, and the patient can be given a better prognosis.

Alongside the return to natural, holistic methods of treatment is an incredible advancement in clinical technology that was not available twenty or thirty years ago. Scientists claim to have identified a set of altered genes that can make an individual more disposed to suffer from congestive heart failure and are using their current knowledge of genes and the benefits of gene therapy to attempt to reverse the effect. In addition, medications to tamp down on the genes’ activities, such as beta blockers and alpha-2 agonists are already available and being used in treatment programs.

Also being explored is the possibility of using stem cells, the body’s pluripotent progenitors, to assist in reparation of the damaged heart tissue. Clinical trials showed that patients suffering from congestive heart failure responded very favorably to an injection of their own stem cells into the heart, although the exact means by which this causes improvement is as yet unknown. It is suspected that these cells either facilitate the growth of new vessels in the heart or act as beacon, attracting the body’s own healing cells to the site of the damage and stimulating repair.

The possibility of actually growing healthy tissue from embryonic stem cells to be transplanted is also being explored, although the controversial nature of the use of embryonic stem cells due to the necessary destruction of the embryo makes this questionable in the foreseeable future. Scientists have determined that adult stem cells simply cannot provide an adequate number of new cells to meet the needs of patients who have suffered heart failure.

Heart failure is incredibly dangerous because the body cannot reproduce the dead tissue cells in the heart; however, with modern advancements it is the great hope of researchers everywhere to one day find a cure.
