Strokes and their contributory factors:
Help society by helping yourself
Are you
susceptible to stroke?
When the blood flow to your brain stops and when the brain cells
begin to degenerate, a stroke occurs. There are two kinds of strokes
where the common ones are called ischemic stroke (caused by a blood clot
that blocks or plugs a blood vessel in the brain) and another called a
haemorrhagic stroke (caused by a blood vessel that breaks and bleeds
into the brain). A stroke can be devastating to individuals and their
families, robbing them of their independence as it is the most common
cause of adult disability.
Stroke is still the second most common cause of death after heart
attacks in Sri Lanka and it can be easily prevented if a good diet is
taken and regular exercise is done. Moreover, bad habits such as
smoking, drinking and stress make healthy people susceptible to strokes.
Smoking is the leading cause of strokes in Sri Lanka's male
population. Having high blood pressure, high cholesterol and diabetes
will increase the risk of stroke. Women are also prone to stroke as they
are workaholics when it comes to providing for their families and they
are affected by stress.
So stop stressing, eat well and exercise while maintaining a good
equilibrium to prevent getting a stroke.
Stroke Prevention Guidelines:
1. Take a blood test and check your blood pressure, cholesterol and
diabetes to know where you stand.
2. Stop smoking.
3. Alcohol intake in moderation, with doctor's advice.
4. Exercise
5. Decrease your salt intake
6. Reduce fat consumption
7. Educate your family members on stroke and how it can impact
financially if there was anyone who had it. |

"By the year 2020, one-third of Sri Lanka's population will be above
60 years, so we need to educate our society in protecting and
safeguarding their health," said newly appointed Director of the
Non-Communicable Diseases unit (NCD) of the Ministry of Health, Dr.
Champa Aluthweera.

One dangerous disease that is becoming ever-increasing in Sri Lankan
society is the incidence of strokes. A majority of the population have
been affected because modernisation and stress has contributed to many
taking up to smoking and drinking as a form of escapism.
"What these people don't realise is that in the long run, such bad
habits lead to strokes which cause adult disability that not only make
them a burden to society and their families but hard workaholics are
reduced to nothingness with such conditions," said the doctor.
The doctor, who has done her post graduate degree in community
medicine, said that plenty of things need to be done at a ground level
in overcoming simple "We can't prevent deaths but we can give medical
advice to stop premature deaths and treat diseases in the best way we
can" said Dr.Champa.
In terms of education and awareness, Dr.Champa said that they can't
always go behind the patients once they are treated and sent back home.
"We hardly have time to spend with our patients since the number of
patients coming to the General Hospital is massive but we can educate
the public to educate themselves," she said. What she meant was there is
plenty of literature and information out there so no patient can give an
excuse that the doctor didn't advise them.
"We have a big elderly population so while we can treat them if they
have any ailments, it is also their duty and their families to educate
themselves lest tragedy occur," said the doctor.
"We are still strengthening our primary care sector because less than
30 percent of our resources are under-utilised. We hope to have a
systematic hierarchy to disperse funds in the NCD in order people to
help themselves," she said.
The NCD has already recruited their respective officers in every
district of the country with the assistance of the Medical Officers of
Health in the areas. "We hope to integrate these NCD officers to educate
and provide valuable assistance to those who need curative care in
specialist fields," she said.
The doctor also highlighted that there have been significant progress
in the patient-doctor relationship and many are now started to report
benefits. It is estimated that there might be a 50% increase in the
number of stroke patients in Sri Lanka because many have not been
heeding advice given by doctors also.
"We continuously advise patients not to smoke or drink but once they
become really weak, they expect the doctors to save themselves at the
last minute," said Dr.Champa. So not only education and awareness but a
more personal connection needs to be made with the public. "We are
thankful to many sponsors for funds in giving us aid to develop our NCD
services but we also need the public to help themselves.
We can always treat and cure but it means ultimate suffering for
those undergoing treatment when they could have stopped diseases" she
said.
Plus, every doctor should get stroke patients to have a CT scan and
often these are not available in every clinic islandwide. So the NCD is
opening up Healthy Lifestyle Clinics around the island in order to give
better information and advice to patients and their families as well as
CT scans to check patients.
"Even those affected by strokes and have disabilities can make full
use of these clinics to prevent another stroke from happening," said
Dr.Champa. "There are long-term treatment techniques like exercise and
physiotherapy which is now used to heal stroke patients," she said.
Strokes affect 11 patients per 1,000 population in Sri Lanka being
the second leading cause of hospital deaths. Stroke is the world's main
cause of adult disability and according to the World Health Organisation,
the loss of productivity caused by the disability and the cost involved
in the management of stroke could be significant enough to have an
impact on the economy of a country.
Soy may reduce breast cancer risk
Consume a lot of soy products if you want to cut back on the risk of
breast cancer, says a new study, with Indian specialists agreeing that a
protein in soybean acts like a medicine that is used to cure the
disease. "
The rate of breast cancer has always increased or decreased with food
habits. Breast cancer rates are high in western nations as compared to
women living in China and Japan where people consume high soy diet since
childhood," Sameer Kaul, senior consultant, oncology, at Apollo Hospital
told IANS. Soy protein is a high quality protein equivalent to the
protein quality of egg, milk or meat. Soybean is a functional food of
this millennium with complete protein package, containing essential
amino acids that are required by the body.
With almost 40 percent protein, soybeans are higher in protein
content than other legumes and numerous animal products and high soy
intake during adolescence can reduce the risk of breast cancer in the
pre-menopausal years by about 25 to 50 percent, suggests a recent study
in the US.
Larissa Korde, principal researcher at the Clinical Genetics Branch
Division of Cancer Epidemiology and Genetics, National Cancer Institute,
US, in her report found that soy intake from childhood was significantly
associated with reduced breast cancer risk.
Korde is an assistant professor in the University of Washington (UW)
division of Medical Oncology.
According to the study, the isoflavone protein in soy inhibits the
growth of cancer in men (prostate cancer) and women (breast cancer).
"Isoflavone in soybean acts like tamoxifen, a medicine which is used
to cure breast cancer. Women with a high lifetime exposure to estragon
have greater risk of breast cancer. So, isoflavone exerts an
anti-estragon effect at some body tissues which may explain the reduced
risk of breast cancer," said Anupama Hooda, chief of medical oncology at
Max Health Care Superspeciality Hospital.
Hooda says that soy should be consumed from its natural sources -
plant products like tofu and miso. Soya products like soy milk, soybean
chunks, sou-flour, soy papad, soy cookies and soy namkeens can also be
consumed instead of taking pills having high soy proteins. Talking about
the ill-effects of soy pills, Hooda said: "Isoflavones in the pill
thickens the blood since they are processed and can bring about clumping
red blood cells which is not a good sign."
"Consuming soy food consistently at an early age is always better
than going for hormonal replacement therapy opted by women to remain
young as it increases the period of menopause and also increases the
risk of breast cancer," said Rohit V. Nayyar, senior consultant,
oncology, Apollo Hospital.
The study further concluded that no significant association with soy
food consumption was found for post-menopausal breast cancer.

Obesity can affect your sexual health
It is well-known that obesity increases one's risk of developing type
2 diabetes, heart disease, stroke, high blood pressure and certain types
of cancer, among other health problems. Now, a new study has concluded
that obesity can harm an individual's sexual health too. During the
study, it was found that the rate of unplanned pregnancies is four times
higher among single obese women than normal weight women, despite them
being less likely to have been sexually active in the past year.
Obese women are less likely to seek contraceptive advice or to use
oral contraceptives.
Obese men have fewer sexual partners in a 12-month period, but are
more likely to suffer from erectile dysfunction and develop sexually
transmitted infections than normal weight men.
The research led by Professor Nathalie Bajos, Research Director at
the Institute National de la Sant et de la Recherche Medicale in Paris,
is the first major study to investigate the impact of being overweight
or obese on sexual activity and sexual health outcomes such as sexual
satisfaction, unintended pregnancy and abortion.
The authors undertook a survey of sexual behaviours among 12,364 men
and women aged between 18 and 69 years of age living in France in 2006.
Of the participants, 3,651 women and 2,725 men were normal weight (BMI
between 18.5 and 25), 1,010 women and 1,488 men were overweight (BMI
between 25 and 30) and 411 women and 350 men were obese (BMI over 30).
The results showed that obese women were 30 percent less likely to have
had a sexual partner in the last 12 months. Obese men were 70 percent
less likely to have had more than one sexual partner in the same period
and were two and half times more likely to experience erectile
dysfunction. ANI
As a result of a discovery in a Cambridge laboratory:
A cure for the common cold?
by Steve Connor
Virus (purple) circulating in the bloodstream recognised by
antibodies (yellow) of the immune system.
In a dramatic breakthrough that could affect millions of lives,
scientists have been able to show for the first time that the body's
immune defences can destroy the common cold virus after it has actually
invaded the inner sanctum of a human cell, a feat that was believed
until now to be impossible.
The discovery opens the door to the development of a new class of
antiviral drugs that work by enhancing this natural virus-killing
machinery of the cell. Scientists believe the first clinical trials of
new drugs based on the findings could begin within two to five years.
The researchers said that many other viruses responsible for a range
of diseases could also be targeted by the new approach. They include the
norovirus, which causes winter vomiting, and rotavirus, which results in
severe diarrhoea and kills thousands of children in developing
countries.
However, a study by a team of researchers from the world famous
Laboratory of Molecular Biology in Cambridge has shown that this
textbook explanation of the limits of the human immune system is wrong
because anti-viral antibodies can in fact enter the cell with the
invading virus where they are able to trigger the rapid destruction of
the foreign invader.
"In any immunology textbook you will read that once a virus makes it
into a cell, that is game over because the cell is now infected. At that
point there is nothing the immune response can do other than kill that
cell," said Leo James, who led the research team.
But studies at the Medical Research Council's laboratory have found
that the antibodies produced by the immune system, which recognise and
attack invading viruses, actually ride piggyback into the inside of a
cell with the invading virus.
Once inside the cell, the presence of the antibody is recognised by a
naturally occurring protein in the cell called TRIM21 which in turn
activates a powerful virus-crushing machinery that can eliminate the
virus within two hours - long before it has the chance to hijack the
cell to start making its own viral proteins. "This is the last
opportunity a cell gets because after that it gets infected and there is
nothing else the body can do but kill the cell," Dr James said.
"The antibody is attached to the virus and when the virus gets sucked
inside the cell, the antibody stays attached, there is nothing in that
process to make the antibody to fall off.
"The great thing about it is that there shouldn't be anything
attached to antibodies in the cell, so that anything that is attached to
the antibody is recognised as foreign and destroyed." In the past, it
was thought that the antibodies of the immune system worked entirely
outside the cells, in the blood and other extra-cellular fluids of the
body. Now scientists realise that there is another layer of defence
inside the cells where it might be possible to enhance the natural
anti-virus machinery of the body.
"The beauty of it is that for every infection event, for every time a
virus enters a cell, it is also an opportunity for the antibody in the
cells to take the virus out," Dr James said.
"That is the key concept that is different from how we think about
immunity. At the moment we think of professional immune cells such as
T-cells [white blood cells] that patrol the body and if they find
anything they kill it.
"This system is more like an ambush because the virus has to go into
the cell at some point and every time they do this, this immune
mechanism has a chance of taking it out," he explained.
"It's certainly a very fast process. We've shown that once it enters
the cell it gets degraded within an hour or two hours, that's very
fast," he added.
The study, published in the journal Proceedings of the National
Academy of Sciences, involved human cells cultured in the laboratory and
will need to be replicated by further research on animals before the
first clinical trials with humans.
One possibility is that the protein TRIM21 could be used in a nasal
spray to combat the many types of viruses that cause the common cold.
"The kind of viruses that are susceptible to this are the
rhinoviruses, which cause the common cold, noravirus, which causes
winter vomiting, rotavirus, which causes gastroenteritis. In this
country these are the kind of viruses that people are most likely to be
exposed to," Dr James said.
"This is a way of boosting all the antibodies you'd be naturally
making against the virus. The advantage is that you can use that one
drug against potentially lots of viral infections." "We can think of
administering these drugs as nasal sprays and inhalers rather than
taking pills... It could lead to an effective treatment for the common
cold," he said. "The beauty of this system is that you give the virus no
chance to make its own proteins to fight back. It is a way for the cell
to get rid of the virus and stay alive itself." Sir Greg Winter, deputy
director of the MRC Laboratory of Molecular Biology, said: "Antibodies
are formidable molecular war machines; it now appears that they can
continue to attack viruses within cells.
This research is not only a leap in our understanding of how and
where antibodies work, but more generally in our understanding of
immunity and infection."
