Breakthrough Technology Enables Communication in Late Stage ALS

brain computer interface
For family member of the patients who are suffering from Amyotrophic lateral sclerosis (ALS) will finally have a reason to rejoice. A new revolutionary technology has been developed by the scientists will have them getting back the communicational ability in a noble fashion. ALS is described as a rapidly progressive and intensely rare disease which results in patients gradually their complete motor functionality. It essentially leads to the degeneration as well as ultimate death of the motor neurons which removes the ability to move around or communicate at all.

More than two third trial patients responded correctly

A brain-computer interface (BCI) technology is developed by a team of doctors and scientists which is led by Prof. Nield Birbaumer in Geneva, Switzerland. The BCI technology takes advantage of the ‘functional near infrared spectroscopy’ (fNIRS) which has the ability to enable the communication even in the patients who are in completely locked in syndrome. Their study has been published in a reputed science magazine called PLOS Biology.

Four patients suffering from ALS agreed to be part of this revolutionary technology trial and led to its success. This technology specifically detected responses from the patients on a series of simple question which requires ‘yes’ or ‘no’ answer by thinking the answers. This was done by carefully measuring the changes in the blood oxygen level of the brains. A number of earlier theories have cemented the understanding that patients suffering from locked’-n syndrome are completely unable to perform goal directed thinking but researchers found that their technology prompted in getting correct in 70% of the trials.

Technology set to bring a positive impact on human life

This technology was trialed on four patients suffering from the ALS and they were able to regain a kind of communicational ability wherein they provided valuable response to doctors questioning. All these patients are suffering from the locked-in syndrome where they can’t even move their eyelids to reflect any form of communication but this technology enabled them to communicate by carefully analyzing their breathing and other brain patterns. Doctors has emphasized that these patients were on artificial ventilation in order to sustain their as they were unable breathe on their own but their interaction with this technology resulted in positive impact.

The questions asked by the scientists to emit response from the patients were simply straight forward and easier to understand in nature. These questions included ‘Are you happy?” and other questions like that and this questioning was repeated over few weeks with answers being consistently ‘yes’. In one such session a family member of the patient insisted on asking a particular which was whether he would allow his daughter to be married with the boyfriend. This question was repeated over 10 times over different time period and the response was simply ‘no’ for 9 times altogether. One of the doctors associated with this technology and trial stressed that this technology is the first crucial step which help patients with locked in syndrome in regaining movement in future.

Paralysed Patients Communicate Thoughts via Brain-Computer Interface

Brain-Computer Interface

Healthcare is going through a decisive decade wherein technology is advancing at an incredible pace to enhance the longevity of the human race along with offering some incredible solutions to age old problems. Quite recently a team of scientists has been able to develop a highly advanced brain-computer interface which has the ability to read brain’s blood oxygen level in order to bring communicational abilities to the paralyzed patients.

This interface essentially helps in deciphering the patient’s thoughts and allows them to communicate. During the initial trial of this system scientist has taken help of four patients who are suffering from complete locked-in syndrome wherein they are unable to a single part of their body to facilitate communication. Thereby their thought waves were analyzed to bring responses in either yes or no through a list of questions.
Brain Computer interface (BCI) will transform millions of patient’s life

Researchers have asserted that the brain-computer interface (BCI) developed by them is non-invasive in nature. It will help in effectively transforming lives of millions of patients by giving them an opportunity to express their feeling and opinions. Patients who can only lift their eyes up and down in form of active body movements is classified as enduring locked-in syndrome when even such ability is lost then it results in complete locked-in syndrome. BCI will help such patients in communicating again and with further progress in the technology they will be able regain their body movement.

More details into the development of this system

Scientists has made trail of this system on four patients effectively suffering from amyotrophic lateral sclerosis (ALS). ALS is defined as a progressive motor neuron disease which gradually destroys a patient’s nervous system which controls of the body movement thereby paralyzing him for life. They have published their trial and its finding in the journal on Tuesday called PLOS Biology wherein they provided some of the insightful studies of their trial.

The questions put forwarded to the patients were to be responded in either yes or no and it included basic questions such as whether their husband name is correct or not or are they are happy. The technology used to measure their responses by effectively measuring their blood oxygenation and brain electrical activity was made up of near infrared spectroscopy and the electroencephalography or EEG.

How this system works? 

This particular system devised by the scientists actually keeps a record of the blood flow and oxygen level then calculates how these levels changes during the ‘yes’ or ‘no’ responses by the patients. Over the time this system learns from this and develops a pattern which is able to accurately predict/calculate patient’s responses with precision.

John Donoghue the director of Wyss Center has appreciated the breakthrough made by the scientists and he states that this could be the first step in helping such patients in regaining their movement. His team has next task at hand that is to develop this particular system and technology further to make it available to wider number of patients suffering from strike, spinal cord injury or ALS.

Smart Baby Trackers Mostly Unnecessary

owlet
The rising trend among the parents to track and monitor the movements of their off-springs through advanced technological racking equipments and gadgets has been dubbed as waste of money. Now the doctors in US is looking forward to get the smart health trackers for babies to be regulated by a US body which overlooks the development and intricate working of other medical equipments. This might come as a surprise for a number of parents which actively indulge in monitoring their babies in sleep.

How smart baby trackers works? 

The smart baby trackers are made up of highly advanced monitors; are equipped with varied forms of sensors. These sensors are fitted to the baby’s clothing or nappies and it helps in measuring signs which includes the heart rate as well as breathing rhythm during the sleep. The data generated from the trackers are shared with the parents with a phone based app.

A team of doctors from Children’s Hospital in Philadelphia has opined that the baby tracking devices should be approved by The FDA. The major reason for this is attributed to the fact that one of the brands named Owlet sells its baby monitor for $250 and it proactively helps in tracking sleeping baby’s breathing and heart rate. This happens through the help of a sensor which has to be placed inside baby socks. Owlet has stated on its website it has submitted an application on FDA site for approval. But without proper authorization from FDA such devices shouldn’t be allowed to be sold to the general public as it can have adverse impact on the baby’s health.

The health risks of monitoring devices

A neonatologist named Dr Elizabeth Foglia has stated that keeping baby’s healthy shouldn’t be compromised with the use of unapproved health monitoring devices. It has been found that adopting the monitoring devices has not resulted in reducing the risks of the Sids (Sudden Infant Death Syndrome). Furthermore there are few classes of babies which shouldn’t be brought in close connection with the monitors unless it has been prescribed by the physician. Another problem which might arise from the continuous monitoring of the infant health is that it can results in raising false alarms with regular changes in the body. An infant body is going through rapid development which results in a number of physiological changes.

The risk of false alarms

An analyst at CSS Insight named Ben Wood has shed light on this trend by stating that new parents are seduced by the baby tracker manufacturers. Manufacturers are specifically targeting the young parents by carefully merchandising their gadgets as a tool of offering best start in life to the babies. The health services present in the country are already stretched and such products are only going to make things worse. These products can easily end up in raising the false alarms which will cause undue trouble for the parents and eventually lead to the healthcare facilities based on the futile alarms.

Three-parent baby born to infertile couple in world first

fertilization
A highly experimental birth technique was conducted by few reputed doctors in Ukraine with miraculous results. An ordinary Ukrainian couple was trying to conceive a baby for almost 10 years, and was disappointed with no results. The desperate need of the couple for their own baby also made them go through four rounds of IVF.

However, the results were still negative and they had almost lost of the hope of having their own children. IVF is the test tube baby technique in which the sperm and egg are manually combined in a laboratory. The doctors tried to create a new type of three-person IVF and were successful in doing so. For the first time, this three-person IVF procedure has allowed this infertile couple to become fertile and have their own child.

Three-person IVF method 

This couple was blessed with a baby boy using a new technique called the pronuclear transfer, and the doctors regarded the technique as being ‘highly experimental’. In Kiev, the doctors fertilized the father’s sperm with the mother’s egg into another egg donated by an anonymous (name not revealed) woman.

Valery Zukin, the supervisor of the entire procedure revealed, that later this egg was again implanted into the womb of the mother, who gave birth to the child naturally. The couple was completely awe-struck by the news and at first couldn’t believe that such a miracle was really possible.

Scientists claim the method to be unsafe 

The three-person IVF procedure is not entirely new, and has been used previously for preventing inheritance of genetic disorders. However, this was the first time that the same was used as a potent method of treating infertility. The director of Nadiya clinic, Kiev remarked that this particular procedure is effective and could be used in the future to help women in their 40’s to give birth naturally, using their own eggs. However, other scientists have stated that this procedure could not be scientifically tested and that it could give false hope to infertile women trying to conceive.

Dr. Zukin further added that this procedure is highly effective for infertile women suffering from the condition commonly known as ‘embryo arrest’. This is an uncommon condition and is suffered by 1 out of 150 IVF patients.

In this condition, the embryo of the patient simply stops growing even before it’s implanted. This new pronuclear procedure has not yet been scientifically proven as stated by the chairman of British Fertility Society, Adam Balen. They are also quite cautious about espousing this method for improving IVF outcomes.

The baby boy has a tiny amount of DNA from the anonymous woman and has inherited its genes from his original parents. Yesterday the Nadiya clinic in Kiev announced that the child was born healthy on 5th January, 2017. In response to the scientists’ statements of this method being unsafe, Dr Zukin stated that they ought to try a new procedure for knowing its outcomes correctly. The couple had gone through 4 IVF cycles, and could never conceive even after 10 years of trying. HFEA approved the new procedure and this is considered as a historic decision.

Blood Repellent Materials: A New Approach to Medical Implants


Blood Repellent Materials
The medical assistant that is being provided to several human beings does enable immediate relief to the patients from the concerned ailment but at the same time bears several side-effects that can lead to further health problems. With the up-gradation in the field of science and technology, medical science has answer to every serious health issues. But, it should be kept in mind that these newly developed remedies do not become the reason behind several other problems.

One of the biggest problem these days have been discovered that gives a negative dimension to new high techniques of curing diseases is that stents, catheters and tubing bears the risk of blood clotting and infection. This situation has become very common amongst several patients, which is even life threatening.

As per the research done in the Colorado State University, suggests that this is definitely a very obvious problem but they even have discovered a solution to this. The engineers there say that if a properly grown surface of titanium referred to as superhemophobic which is remarkably repulsive to blood can solve the problem. They even assured that this material can be confidently used for surgeries as it has the lowest risk of being hazardous to health in comparison to other materials which increases the risk of future ailments.

This solution has been forged out of two theories .The two developing disciplines has recently been published in Advanced Healthcare Materials by assistant professors in the department of medical and biomedical engineering, Arun Kota and KetulPopat.

Kota who is an expert in seperomniphobic materials, one day during his experiments discovered that titanium and blood act as highly repulsive stuffs. He and others who were involved in this experiment came to a conclusion that this can be used in terms of medical surgeries as adhesion of platelets is very low in terms of titanium and blood. So, if titanium is used by the surgeons then the risk of blood clotting can be averted.

The whole crux of their invention is that they are suggesting to use a material that is tremendously undesired by blood. The titanium surface turns out to be so repulsive that blood can be tricked into accepting that there isn’t any presence of an undesired material, which makes the situation appealing and hence, any risk can be easily avoided. It is all about tricking blood in terms of its high resistant capabilities.

Blood is always taken to be an unfavorable material for interaction which leads to several other problems in the area of medical science. Students of this field in the due course of time learn how to form clots, and several other problems like heart attack or embolisms just by making blood react to its enemies.

Researches are still being carried to find several other materials that acts as of high repulsive value in terms of blood and hence materials should be tested in labs before they are used for any surgeries.

carbapenem resistant Enterobacteriaceae 'nightmare bacteria' Harvard study declares

CRE
CRE the antonym for carbapenem resistant Enterobacteriaceae is one of the most dangerous and scary widespread bacteria which is resistant to antibiotics. With studies being conducted to find the effects of it and how hard it is to deal with, CRE has been branded with the tag of being the ‘nightmare bacteria’. The name was done after the studies found out that the CRE has been immune to even the last resort antibiotics.

In a recent research undertaken by the Harvard scientists, the earlier knowledge about the CRE seemed faint as the same has been found to exist with much wider appearance and disaster. The CRE is known to exist in various species across the country with each species dealing with its own medication needs and fighting.

The species of CRE is found to be spreading and getting shared in new species with medication resistance. And the spread of the same is happening from person to person without any visible symptoms. While most medications are focused on treating the infections caused because of CRE, the new research have brought the tension more intensely as the cases are understood to be more intense than it seemed. Some medications might just not be able to treat the CRE that exists with no visible signs or infections.

For fighting with the CRE there is a need to observe and study the pattern of the transmission of the bacteria in communities and improve the healthcare facilities says the associate professor of epidemiology at the Harvard Chan School and also the senior author of study, William Hanage.

CRE is a bacteria which is proven to be resistant to antibiotics. The class of bacteria has been under study since years and has been found ineffective and immune to even the last resort drugs and antibiotics which even include the carbapenems. With a widespread presence in communities, and transmitting through patience in hospitals and healthcare centers, the bacteria has caused about 600 deaths in USA each year with about 9300 types of infections.

The researchers picked about 250 samples from hospitals of Boston and California to study its effects with aims which mainly were:

  • CRE’s generic diversity 
  • CRE’s outbreaks and its process-timings 
  • The study of CRE spreading in hospitals and people 
  • Learn the spread of resistance because of CRE in different species 

Dr Hanage’s study revealed that a riot of diversity existed both in the CRE species as well as carbapenem genes resistance. The research also stated that there is free movement of bacteria from species to species and thus an increased threat because of CRE. The resistance to the CRE is found to be more than ever and is evolving with time which shall make the practice of solving the mystery even more difficult with each passing day. And thus scientists insist genomic surveillance of these dangerous bacteria to get clearer understanding and control over the mechanism in which it works.

The scientists are finding ways to stop the transmission as an early measure to fight against the resistance which shall prove helpful in achieving major understanding and creating ways to fight with it. The treatments shall be effective only when the transmission is stopped and the study is being conducted for that too!
