SriDevi – A Victim of Sudden Cardiac Arrest – Know About Sudden Onset

The legendary actoress, a versatile actor, a super star, epitome of grace – Sridevi left every fan of hers across the world in shock as she made her way to the heavenly abode. Only 54 years of age, a fitness freak, one who maintained a healthy lifestyle all through her life passed away in such a shocker, all of a sudden cardiac arrest of massive nature.

It took so much time to come to terms with this saddening or heart wrenching fact and still is unbelievable because we lost her at such a young age of 54, in a film industry where actors like Salman, Shahrukh and Amir at 50 are still playing lead roles and setting the box office on fire with hundreds of crores their films rake in when they release.
Now that we know that sudden cardiac arrest can happen irrespective of aging here is a short note on what it is all about, the symptoms and treatment.

Sudden Cardiac Arrest – It occurs all of a sudden without a clear sign. Symptoms might be there but not indicating clearly of a heart issue. In a sudden cardiac arrest case, the heart stops functioning suddenly due to some disturbance and disrupts blood flow. The blood supply to heart as a result is cut off. Sudden cardiac arrest requires prompt medical intervention in order to increase survival chances.

Symptoms – The symptoms usually are not very clear and may be underlying. This symptoms include Dizziness or fatigue, shortness of breath, heart palpitations and chest pain around 4 weeks before the attack. The symptoms vary in men and women. People who suffer from chest pain may have it secondary accompanied with primary pain of head, shoulder and neck or back.

Risk Factors
Though sudden cardiac arrest occurs out of the blue without clear signs, some risk factors responsible on a long run include diabetes, high cholesterol levels, smoking, obesity and high blood pressure to name a few. Sometimes genetics is also responsible for causing a sudden arrest to people who are fit and have no medical history of heart disease like Sridevi’s case.

Treatment – Sudden Cardiac arrest is a highly life threatening condition which can lead to death in most cases if not given immediate medical aid. You need to offer CPR as primary treatment or use a defibrillator for the same. You can even give chest compressions until the help arrives. If medical aid is provided instantly and properly, survival is possible.

Well, it’s advisable to follow a healthy lifestyle and go for a routine checkup one every year once you cross 50 years of age.

Dementia Risk and Blood Magnesium Levels

Before we talk about risk factors associated with dementia lets just polish our information around the condition. This condition usually occurs at an older age and causes memory loss. Alzheimers is one of the most common forms of dementia known. Apparently, its not a condition by a symptoms or group of symptoms rather. You should also know that it does hamper our day to day routines because we tend to forget a lot. Dementia symptoms are also caused due to vitamin deficiencies and thyroid problems. Dementia occurs due to brain cell damage and most of them are generally permanent or increase with time.

Now, a study has found out that the levels of magnesium in your blood can associated to the risk of dementia later in life. The people with lower or higher levels of minerals in the body were subject to dementia more compared to the ones with middle levels. It has yet to be proved and nowhere confirm that it causes dementia but definitely magnesium levels do have a link with dementia. There are apparently two ways in which magnesium levels could be called as risk factor for dementia.

Coming back to the study, around 10,000 participant around 65 years of age were studied across 8 years span and their magnesium levels were checked at the beginning of the test. They were divided in 5 groups. The study findings showed that those with low and high level magnesium had 30% greater risk of dementia compared to mid level magnesium level participants. The lower and higher magnesium range is below 0.85 millimoles per liter and 1.10 mmol/L respectively. Though as the magnesium levels were not measure post eight years the results could have associated limitations.

Well, to prove that magnesium levels do determine the risk of dementia in later stages of life, further detailed study is required.

Tatoo Ink and Side Effects – A Short Review

Before we get to the question that whether tatoo ink is harmful to the body or not just quickly understand the process through with tatooing is carried out. The tatoo artist, to make a permanent tatoo uses hundreds of needles for pricking into the skin and delivering ink into the dermis. Now, dermis as well know lies below the epidermis layer of skin and consists of nerves and blood vessels. Yes, its obviously painful and to make a tatoo isn’t less than an act of bravery for many. The point in question is that many of us really wish to have permanent tatoos and many of us may already have had one but rarely anyone of us has ever thought about the side effect of inking at all.

But, we do have a few curious heads called researchers and scientists who are apparently trying to figure out whether this tatoo ink is harmful or not. Now, research findings show that once the ink is delivered by the tatoo artist inside the dermis, it moves to the lymphatic system through the blood stream to the lymph nodes. This is because of the carbon black in the ink which has the ability to break down into nano particles fast and spread through blood. But, sometimes tatoo ink also consists of nickel and chromium additions particularly in organic tatoos. In mice it has also shown to reach the liver. Reaching the liver might take some time but as per dermatologists within minutes of insertion the ink particles reach the lymph nodes.

Now let us understand what happens to the tatoo pigments after the tatoo is done. Some of the ink gets cleared but some is not cleared by the repair cells known as macrophages and remain trapped within the skin cells and showing out through the skin as a tatoo. Generally the ink does not go very far from the point it is injected but some of it does have the ability to travel to the lymph nodes. Research has also shown that many of the individuals with enlarged lymph nodes have been the ones with tatoos for more than a decade.

Well, but it is yet to be proved if tatoo ink is apparently harmful to the body or not. Research is still in progress to say the least.

Brain Has Eyes Too – A sneak Peek Into Neurons

Yes, that is true. Nicknamed as ‘Jennifer Aniston’ a neuron based on the participant study which showed that one of the neuron of his brain lit up on recognizing the face of particular people like Jennifer Aniston or Hillary Clinton. So, this neuron was named after Jennifer Aniston. This report further revealed that one single specific cell lit up whenever a person’s certain conscious experience was concerned. This throws further light on the response of brain cells the relation of the activities with consciousness. Though, understanding the scope and science of human consciousness is a mystery that is yet to be unfolded and even researchers cannot say with surety if these neurons lead to conscious thoughts.

There were studies around the same carried out in 2008 which used a masking technique. This technique showed an image of a popular person like Aniston for 16 milliseconds immediately followed by a pattern Image muddling the face afterimage on the retina, thus making it rather hard for the brain to register what it saw. Later on in another study that used a method for hiding images from participants awareness. The phenomenon used for the experiment is called attentional blink wherein two target images are shown in a high speed streaming along with some other similar images. This results in a person often not able to recognize the second image targeted.

A similar study was carried out over a list of 21 patients under epilepsy and brains were fitted with special treatment electrodes. The trial included showing 14 different images predetermined by the scientist as familiar to the person. Further each one had a particular activity of specific brain cell. Now, when the trial was conducted, the researchers asked the participants to concentrate on two target images of the 14. All the images would later be flashed on the screen for 150 milliseconds. The medial temporal lobe was under constant monitoring during and after the trail and the researchers queried the participants if they had seen two images of familiar faces.

Every cell with unique signature was studied as it lit up and helped researchers link a brain cell pattern to particular images and had the ability to tell about the image represented even though
the participants are not aware of it.

Furthermore, research work is on as the researchers believe that they are at the intersection of perception and memory and investigation was needed to find out the results of direct stimulation of neurons.

Lower Back Pain vs Kidney Pain – The Difference

Many of us fail to figure out the difference when we experience pain particularly when its either kidney or lower back pain. So, to begin get down to the definition of lower back pain and kidney pain.

It’s called lower back pain when it occurs anywhere from the buttocks upto the lower back. While kidney pain is said to occur between the hips or flanks and the ribs. At times you may experience it in the upper abdominal region as well. Well, this is the basic difference in back pain and kidney pain but otherwise also there are many other difference that can help you figure out which kind of pain you are suffering from. Here’s a sneak peek into a few other differences between kidney pain and lower back pain.

Kidney Pain
Kidney pain is the result of a kidney infection or a kidney stone usually. Kidney infection can cause mild pain but kidney stone pain is very severe in nature and often compared to labor pain.

Causes
The causes of kidney pain include kidney infection and kidney stones as mentioned before besides the pain could also be a result of renal infarction, kidney cancer and glomerulonephritis.

Lower Back Pain
Lower back pain is further divided as acute pain and chronic pain. While acute pain lasts for around 4 to 12 weeks, chronic back pain can easily last over 12 weeks. Also known as lumbago it affects people of all age groups.

Causes
Lower back pain is a result of muscle sprain, spasm or tear leading to disc bulge or herniation, spinal stenosis, osteoporosis or sciatica. It could also be due to vertebral body, pedicle fracture or fracture of lamina. It can be caused due to Paravertebral muscle spasm or metastatic vertebral cancer.

Pain Management
Kidney Pain – Kidney pain treatment depends of its causes and usually involves use of antibiotics and medications if its infection but in case of kidney stones if that does not work a laser surgery or a minimally invasive surgery could be carried out.

Back Pain – For relief against lower back pain issues treatment could include suitable therapies like heat and cold, physical and massage therapies to name a few. In case with complications based on the diagnosis surgical procedures might be advised.

Well, its always advisable to visit your doctor if you suffer from back pain in order to figure out the root cause of the problem, be it kidney or lower back.

Gallbladder Sludge – An Overview

Gall Bladder, a small organ inside our body but none the less is equally important as it has a unique function to perform just like every other organ. Gall bladder is responsible for acting as a reservoir for the bile, collecting it, concentrating it and emptying it into the bile duct. The bile duct further takes it to the small intestine for digestion.
The sludge in the gallbladder is known as biliary sludge and is also considered as microscopic form of gallstones. This sludge is generally made up of cholestrol and other particles as well as calcium and sodium crystals.

People suffering from this conditions have symptoms like bloating, diarrhea, vomiting, nausea, indigestion, sweating to name a few. Initially the symptoms are mild but with time they start getting worse. Eventually, it could lead to gall bladder stones as well.

Risk Factors / Causes
The triggers of gall bladder sludge include fasting, certain medications, drug abuse, diet high in cholestrol, pregnancy and alcohol addictions. Even attempting a crash diet to go slim can result into gall bladder sludge as with little or no food intake the bile excretion decreases thus retaining the minimal bile in the bladder leading to sludge.

Diagnosis
Symptoms as mentioned before include severe abdominal pain in the upper right side of the body.

Treatment
If gall bladder sludge is diagnosed, doctors do suggest ursodoil, to help break down the protiens if any in the bile. Drinking a lot of water helps in removal of sludge naturally. But, if that does not work then the gall bladder stone needs to be removed from the body.

Prevention
Drinking plenty of water, intake flax seed oil, vitamin C and avoid food with high cholestrol contents.

Well, gall bladder stones can be removed easily with minimally invasive surgeries but its important to seek doctors advice if your symptoms match the above.

5 Supplements Women Need After 30

Many a times, lost in responsibilities around office or home, family or kids women forget about personal health or keep ignoring them. Till women are in the twenties, body is younger and fitter and hence copes in a better way. But, post 30 as you are nearly knocking door of your middle age, is when you really need to look into your bodily needs.
After 30 there are a lot of changes that occur in a women’s body and are more visible after 35 years of age. These include changes in menstrual cycles, urinary incontinence, fibroids, pregnancy difficulties, prominent signs of aging, slow metabolism, but to name a few.

As per experts and specialists supplements can work well in maintaining the balance of nutrients required by the body.

Vitamin D
Vitamin D as we all know helps in a lot of ways that include immunity building, genes regulation, cancer prevention, bone health and more. The best, easy and affordable source of Vitamin D is sunlight. Sitting in the sunlight with minimal clothing for an hour can work well for your body. If not than Vitamin D supplements is the alternative.

Anti- Oxidants
It is in the mid or late thirties that women start noticing fine lines as well as thinning of skin. But, this process of aging can be slowed down with the help for a few minerals and vitamins together known as anti-oxidants. In order to boost immunity besides slowing aging women need to take in atleast 15 mg of Vitamin E. Further taking in 75 mg of Vitman C, which facilitates in vitamin E absorption and Vitamin A for protection against sun damage and eye

protection.
Omega 3 fatty acids/ fish oil
As per doctors, our body needs 3 gms of omega 3 fatty acids per day. These help in keeping our joints health, weight management, keeping our blood fats normal and optimizing brain function. As these are essential fats and our body cannot make them taking mercury free supplements are advisable.

Calcium, Magnesium & Iron
Calcium and magnesium help in bone building as well as producing energy and for better nerve functioning. Iron is also an essential nutrient responsible for keeping you active and protecting against infections as well as maintaining body temperature. As per experts our body requires about 18 mg per day. Though a pregnant and nursing women requires 27 mg and 9 mg per day respectively. Vitamin C and A help a lot in iron absorption.

As a busy woman, you might be occupied with umpteen activities around house, kids and family but its your health that equally matters so do take care of your health as well.

Artificial Limbs That Respond To Thoughts – A Reality That Costs A Fortune

Over the years, scientists have been working on prosthetic limbs that can respond to human thoughts. These projects have been heavily funded by many organizations and defense agencies across the world. A significant development in the direction has now led to the creation of the first ever prosthetic limb that responds to human thoughts much like a real limb.

Earlier, there was news about creation of prosthetic limbs that respond to thoughts but their movement was quite limited and hence, people in need either abandoned them or never preferred to use them. But, as per the doctor of Imperial college London, the new approach which shifts their focus from the muscles to the nervous system has helped them create a limb that responds to thoughts effectively.

According to him, their technology helps them detect and decode the signals clearly. The experiments and testing have been carried out with amputee volunteers and after physiotherapy they have been able to make more extensive movements.

Today, a lot of research scientists are already working and testing bionic arms. There is already and alternative of using brain implants available. But, the benefit of using the nerve from the spine is the compatibility factor, making it usable with existing prosthetic arms that too wire free linking from the brain, as per the researchers at Imperial College of London.

Another example is that of a thought controlled prosthetic being developed at the John Hopkins University, USA. It is being tested on a 50 plus amputee who lost his limbs in an electrical accident as a teenager. It is yet to be clinically tested and find a place in the market. The limbs are called Modular Prosthetic Limbs or MPL and the customer socket inside brain can pick up brain signals that control the arms. Thus, just by thinking the amputee is able to move the limb or limbs. To do the same, the amputee had to undergo a surgery for remapping the remaining nerves of his/her missing arms so that the brain could send signals to the prosthetic. As per the chief engineer at John Hopkins, with the remapping growing deeper, the working will better because of the over 100 sensors fitted in the arm. Another advantage of MPL being its modular design. This design helps in creating prosthetic limbs customized as per individual requirements.

Having said that, as on day MPL costs a bomb, as much as a Maserati car to be precise. Well, scientists are yet to work on a budget prosthetic, affordable to people in need. experts at John Hopkins are also working on creating caps that send signals about brain activity to the robotic arm. As for the market availability, they do hope to make the MPL available to the consumers within a few years.

Microscopic Robots To Replace Doctors Sooner or Later?

Microscopic robots may seem a new phrase but we all are aware of nanotechnology, the word at least if not more. Now, nanometer is equal to one billionth of a meter and is smallest of the scales. It is apparently the size we consider for atoms and cells inside the body. We all know are body is made of millions of cells and atoms but when it comes to treatment, it happens on a greater scale. Cells or atoms are not even visible through the naked eye. So, nanotechnology works at the cellular level thus matching the levels at which our body cells or atoms work. Though, its not perfected as yet, we’ve certainly come out with a lot of solutions based on nanotechnology and are probably heading northward in the arena.

In layman’s language using nanotechnology, we can shrink the medical tools used for treating or intervention in the human body to the size of cells or atoms present inside. Using the right size tool will help intricate interventions with simplicity. Surgeries with complexities and involving heavy blood loss can be done away with using such a technology. There is a lot of scope to this technology, as per the researchers and experts in the field. Be it targeted drug treatment to treating critical illnesses like cancers, where nano scalpels are presently being used for damage repair of individual cells.

Furthermore, there is a possibility of improved biological sensors as well as disease diagnosis in the times to come. Just imagine subatomic robots just like a miniature army of soldiers getting into your body and fighting against the ailment to cure you off, that too without any major blood filled surgeries or incisions.

One of the examples on which researchers are presently working in some part of the world is ‘drug agnostic’. Consider a reservoir miniature in nature filled with a drug that needs to be delivered to a certain part of the body. All this needs to be done in a sustained linear way without using pumps, valves or any electrically powered tool. Its works through the nano channel delivery system (NDS). On the basis of the size of the drug molecules, the nano channel membranes are tailored and implanted below the skin. It then moves through the membranes into the patients body. As per the researchers, presently, the nano channel size is a barrier to its movement and lower the size to 2.5 nano meters would definitely help overcome the snag and also help control the drug delivery speed. Looking at the potential of this project a multi-million dollar grant has been already approved for the same.

Well, the use of microscopic robots for treatment is just at its infancy stage and a lot needs to be worked on yet, but positively it would take less than a decade to see it reach the operation theatres of hospitals and that’s definitely a good sign.

Heartburn Meds Could Lead to Death

Taking medications or tablets is a routine exercise we follow when we suffer from heart burn. The meds are usually available over the counter without prescription and hence we have almost taken it for granted that as they are available over the counter, they are generally safe. One such med that is popular oversees, not as much in India is the proton pump inhibitor or PPI and here is some bad news involving it.

A recent study has proved that people taking proton pump inhibitors have a greater risk of dying compared to the non consumers of the drug. The risk also includes dangerous bacterial infections and kidney disease under its possibility list of PPI consumption. The risk is associated with people taking PPI’s for a longer duration of time. Another heartburn medication that is prescribed by doctors in the USA includes H2b blocker. The comparison study between PPI and H2B blocker consumers revealed a startling result about the risk of dying within the next 5 years being 25% more in PPI consumers than H2 blockers. Also, with people who have been already taking the drug across 2 years, the risk increases upto 50% compared to the H2 blockers.

Though, it is not totally proved and the reasons behind the same are being studied further. Also, the study has covered only whites of the elderly age group and not the youngsters, so whether it affects the youngsters in the similar manner is yet not known.

Experts also stated that many a times doctors do prescribe the medication for a certain period of time only but patients take them up on a regular basis without consult or reassessment. Hence, it is advisable that people who have been prescribed theses medication for a certain duration do their reassessment at periodic intervals. It might just happen that the doctor after monitoring you, simply takes you off the PPI’s.

Well, the crux – it is advisable to avoid taking PPI medications for a longer duration of time and particularly not decide on continuing the medication or using it without prescription on your own. Doctor consult is a must before you continue taking medications like PPI.
