Wireless Implants to Help Paralysed People Walk Again

Spinal cord injuries have been life-changing events of sorts because they tend to paralyze the body partially or completely depending upon the type of injury. Statistics show that every one or two minute a person suffers from a spinal injury. Now, there is a ray of hope with two research studies in recent times. The two research groups implanted electrical devices in the spinal cord directly thus allowing the paralyzed people to walk again and reverse some effects as well.

Electrical Simulation
Over the past couple of months, researchers have been publishing studies that bring forth the fact around levels to which technology could be used in medicine. In the study, researchers made use of electrical stimulation in order to reverse the effects of spinal cord injuries. While the same is being done for over two decades now, the present study has proved to be kind of a milestone in the area. The researchers used the nerves that were not permanently damaged and activated the nerves with the help of artificial electrical simulation. These nerves are responsible for transmitting information between the brain and the limbs.

Study
The researchers named Kendal Lee and Kristin Zhao conducted the study on a patient that was suffering from complete paralysis in the lower body at the Mayo Clinic in the USA. They planted a device called the Epidural electrical simulator (EES) in the lower part of the body where there are healthy nerves. It works in real time and with accurate simulation to desired part of the spinal cord on time. The device is implanted under the skin and makes use of a pulse generator in order to send appropriate signals to the protective layer of the nerves viz. dura attached electrodes. Living with the implanted simulator is not really much different from that of living with pacemaker. Off-course, it is a minimally invasive procedure that does not require a hospital stay. The patient on whom the study was done managed to walk around 100 meters with the help of walking frame due to the spinal implant. EES has been used and tested on patients having paralysis before as well, but the results it has delivered this time are truly phenomenal. But, the catch is that this kind of implant is only possible if some of the nerves in the lower part of the spine are healthy and intact.

The study only proves the level of breakthroughs advancement of technology can bring about as well as how our knowledge on –  how our brain communicates with our body is heading northwards. Now, that there already is proof of it, there is a need of taking the process to the next level viz. carry out larger clinical studies in order to measure the optimum benefits of the treatment and create benchmarks around the same for doctors to follow.

Why does the onset of winter mean Depression to some people?

Many of us are not aware but in some places around the world, it gets dark as early at 4 pm and there are people who suffer from a condition called SAD (Seasonal Affective Disorder). It is caused mainly due to the shorter days, the chilling weather and the onset of darkness as early as 4 pm in the evening. Statistics say that in UK over 29% of the population suffers from this condition and 10% with a condition known as reverse SAD or Summer SAD, because this occurs in Summer’s and not in winter.

Now, you might be wondering that winter and depression is understood but is it that people suffer from reverse SAD in the summer. Aren’t the long summer lazy days a lot of fun. But, depression could be caused due to the increased humidity and heat as well but as such no proof of the same is available as of now. Sometimes even looking at people enjoying summer can lead to FOMO and depression.

As per experts, people who have had episodes of depression earlier are more prone to the possibility of getting this condition than others. Further people who are at the vulnerable to allergies too have a high probability of getting this depression as allergan’s can cause inflammation of the airways thus triggering depression.

The symptoms of summer in the beginning are mild but as it nears the end of spring they start getting severe. These include loss in weight, insomnia, loss of appetite as well as anxiety or agitation. The treatment abroad available for SAD is already approved by NICE and is known as Transcranial Magnetic Simulation (TMS). This treatment does the role of modulating the brain activity affectively thus helping to reduce the symptoms of this condition in a safe and effective way.

Though this condition is not very common in India, it is very common in countries like UK and other parts of the world as well.

Treating Diabetes With Rehabilitation

Having a healthy lifestyle is always a good idea but diabetes is one condition that makes following a healthy lifestyle sort of mandatory as it is a part of the treatment more so. We all know that diabetes is a result of our body’s inability to make insulin and that when you eat food it gets converted to glucose. This is the time when our pancreas release insulin in order to help sugar to get absorbed by the body. Understanding about the role of insulin is what helps us understand that unavailability of insulin can hinder the work of our body system.

Treating Diabetes With Rehabilitation

If there is no insulin then the body cells starve due to unavailability of glucose. This can damage the working of kidney, eyes, nerves and the heart. The most common type of diabetes is type 2, mostly occurring in adults. People with type 2 might be able to prepare insulin but not enough. Symptoms of diabetes type 2 include feeling thirsty, peeing frequently, fatigue, vision issues, feeling hungry, numbness or tingling in hands or feet, to name a few.

Treatment of diabetes is based on the inclusion of a balanced diet together with regular exercise. Medication is also included if even after following a healthy lifestyle, you are not able to maintain sugar levels after these adjustments.

Exercise and a healthy diet does help in controlling sugar to a great extent as it allows glucose to enter the cells without the need for insulin. It also helps in lowering glucose levels as well as the blood pressure. Exercise increases stamina, fitness and energy levels as well.

Patients with diabetes are recommended exercises that are a combination of aerobics and resistance training. The exercise and diet regime is created by physiotherapists and dietitians. The physiotherapists also supervise these exercises until a routine is formed until the patient is in the hospital. The same routine is advised to be followed at home after discharge.

Just like exercise even diet forms and integral part of the health regime of a diabetic. Dietitians in the rehabilitation centres of hospitals teach patients how to manage carbohydrate intake as they can affect the glucose levels. They even provide information on healthy cooking and eating.

Rehabilitation is a holistic approach to diabetes as it includes the balance diet, exercise and medications to improve the quality of life of diabetic patients and manage the disease in a better way.

All You Need to Know About Open Heart Surgery

Open heart surgery is performed when the coronary arteries supplying blood to the heart are blocked and is the gold standard treatment for the same. The condition arising due to blockage of coronary artery is known as coronary artery disease. Open heart surgery is done to regulate the flow of blood through the arteries and prevent damage to the heart. In the procedure, blood vessels from other parts of the body are used to create a bypass. Generally, two to four coronary arteries are grafted for regulating blood flow to the heart.

There are three types of bypass surgeries depending on the number of bypasses done, namely double bypass, triple bypass, and the quadruple bypass.

Open Heart Surgery – Open heart surgery is considered only if the blockage is such that placing the stent is not feasible. Also, if there is severe coronary disease in the left main artery or in multiple arteries and there is high risk of heart damage. To check the exact blockage scenario cardiac surgeons advice on having a complete testing done. An angiogram is used for checking the severity of coronary disease. The other tests done before and after the surgery include electrocardiogram (EKG), blood tests and specific dietary instructions.

Types of Open Heart Surgeries

  • On Pump Open heart surgery

During the on pump open heart surgery the surgery is performed under general anesthesia while keeping the patient on ventilator support. The primary step in the surgery is harvesting the blood vessels. Generally, the saphenous vein in the leg is used as it is long enough to create multiple grafts. Alternatively, if it cannot be used then vessels from the arm can be used. After the saphenous vein work is done, the chest is opened by making an incision along the breastbone. The surgeon cuts the sternum to gain access to the heart.

In traditional or off-pump CABG procedure, the heart needs to be stopped using potassium so that the surgeon does not have to perform the surgery on a beating heart. The blood circulation is kept on with the help of a heart-lung machine and the ventilator is switched off. The machine then does the work of the heart as well as the lungs. The surgeon either removes the existing blood vessel and replaces the same to remove the blockage or reroutes the blood around the blockage. There could be one or more grafts to be performed. Once the grafting is completed the heart is restarted. The sternum is placed in its original position and closed with the help of a surgical wire. The surgical wire helps in providing strength to the bone for healing. Lastly, the surgeon closes the incision.

On pump, surgery is recommended for unstable patients. The surgeon performs the surgery on a still heart so the process is quicker and even the bleeding is minimal. Alternatively, the cons include inflammation/ clotting after surgery, transfusion and fluid retention. Though after on-pump surgery the risk of stroke does increase.

  • Off Pump Open heart surgery

The off-pump surgery is very much similar to on-pump except that the blood flow through the body is maintained by the heart only and not the heart-lung machine as in on-pump surgery. The area to be grafted is held with the help of surgical instruments while the heart keeps pumping. This surgery is done on tentatively 20% of the CABG patients undergoing the surgery for the first time.

This surgery is less expensive surgery compared to on pump and it also reduces the risk of stroke. Also, blood loss and transfusions are less compared to on pump. The hospital stay required is also less. 70% of the patients are not recommended to do the surgery due to the condition. The surgery is not recommended for unstable patients.

Recovery
The recovery period includes staying in Intensive care unit for 24 hours. The chest tubes are removed post 48 hours and then the patient is shifted out of ICU. Once the patient is awake the breathing tubes are removed so that the patient can breathe on his/ her own. Though supplemental oxygen may be given through the nose to help with breathing. The patient will be monitored closely and if he/she is unable to breathe, the breathing tube might be inserted again. Once the patient starts breathing on his/her own, swift rehabilitation steps are put into place. This includes sitting up on the edge of the bed, walking while taking care of the wound and preventing pain, etc.

Life Expectancy
The life expectancy has greatly increased over the years up to 98% people undergoing the surgery can easily lead a normal life as that of the others who haven’t undergone any surgery.
