New method can help doctors diagnose blood infections

Doctors could soon be using an innovative method to diagnose blood infections.

Reports published in mBio, the online journal of the American Society for Microbiology, showed that researchers have come up with a new way to identify bacteria in the blood much more quickly. 

The process consists of three clear steps, where blood cells in the sample are destroyed, bacteria or fungi is assessed and the fingerprints of pathogens are scrutinised. 

Co-author of the study John Walsh said current methods – including gram staining and phenotypic ID tests – are not always effective. They can take too long, which means the patient is missing out on important treatment. 

The new way of doing things will cut the amount of time it takes for doctors to diagnose a problem, enabling them to administer drugs far more promptly.

Mr Walsh remarked: "The primary benefit of getting a rapid identification is making sure the patient is on the right [antibiotic] therapy and to quickly make any needed adjustments to the initial therapy."

He added that the new process uses intrinsic fluorescence to identify microorganisms and this not only helps to lower costs, it also limits the number of mistakes that can be made. 

Laboratory tests showed the method can correctly identify the cause of the blood infection in 96.5 per cent of all test samples. 

In the 2.7 per cent of samples where no species identity is provided, the system could find the right family of bacteria 67 per cent of the time. This, Mr Walsh stated, is enough to allow doctors to make an informed diagnosis. 

The team are now working on making a fully-automated process by introducing robotics. 

"Our vision is to have a system that will automatically identify the blood culture isolate within 15 minutes of the culture being called positive," Mr Walsh continued. 

The new method could help to reduce the number of people dying from sepsis – a life threatening illness that occurs when the body overreacts to an infection.

According to the NHS, there are more than 30,000 cases of severe sepsis reported in the UK every year and this figure is thought to be rising.

Patients should have earlier access to drugs, Expert Group says

Innovative medicines should be made available to patients at the earliest possible stage.

This is according to the Expert Group on Innovation in the Regulation of Healthcare and the body wants to see an acceleration in the distribution of drugs if there is an unmet medical need. Legal flexibilities already exist in this area, but it does not believe they are being used effectively. 

Instead, the Expert Group thinks the Medicines and Healthcare Products Regulatory Agency (MHRA) – the body responsible for regulating all medicines and medical devices in the UK – should be pressurising the European Medicines Agency to call for adaptive licensing at the earliest possible opportunity. 

By doing so, companies would be able to put forward pilot products to use these flexibilities – as a result the group supports the proposed UK early access scheme for unlicensed medicines.  

It also believes the government should consider accommodating within the system a process whereby a product can be identified for a potential candidate for the early access scheme.

Dr Ian Hudson, chief executive of the MHRA, said: "The MHRA is committed to playing its part in creating an environment that will encourage innovation and help patients get faster access to new, innovative medicines and treatments.

"We want to see improvement in the health of millions of people. There are a range of regulatory tools that can be appropriately used to allow innovative products to be developed in an optimal way for the benefit of public health."

He added organisations can get in touch with MHRA to get both scientific and regulatory advice. 

A report created by the Expert Group has now been passed on to the Department of Health and the Department for Business, Innovation and Skills, who are set to consider it before making an announcement about the next course of action.

Brain technology could aid the recovery of stroke victims

New technology that relies on 'virtual reality hands' could help stroke survivors regain the use of their limbs.

A small scale study has been carried out by the University of Minnesota in Minneapolis and it suggests a brain-computer interface can help the physically impaired make a better recovery. 

Presented as part of the American Heart Association's Scientific Sessions 2013, the investigation sought to ascertain how important it is for people to practice mental imagery if they are struggling to move their hands and arms. 

Alexander Doud, lead author on the research project, revealed the virtual reality hands are controlled by stroke survivors' thoughts. 

He added: "During rehabilitation, usually a therapist will move the patient's hand or arm in the desired direction while asking that patient to imagine they are making the movement. In this practice space, the patients can control photorealistic hands by thinking about using their own hands without actually moving at all."

Statistics from the Stroke Association show that there are over 152,000 strokes in the UK every year, while there are approximately 1.1 million stroke survivors. This demonstrates how significant this study could be if it helps people regain the use of their limbs. 

Patients taking part in the study achieved an 81 per cent accuracy when it came to reaching out for a glass of tea or water with the virtual hands. They had only be given three two-hour sessions before being tested. 

Mr Doud remarked the system can be personalised quite easily, so specific motivating goals can be achieved. He thinks the next step is to have the same set of results replicated in a much larger study.

However, the expert is confident about the system's usefulness, as it encourages stroke survivors to exercise parts of the brain that have been damaged or weakened, while it can be used alongside traditional rehabilitative therapy.

New drug development technique could be revolutionary

Scientists may have come up with a new technique that has the potential to revolutionise the drug development process.

A team of researchers from the UK, US and Italy have honed a process that enables them to engineer specific functions into a protein.

Led by experts at the Department of Cardiovascular Sciences and Department of Biochemistry at the University of Leicester, the group have proven the new system works by taking a protein normally found in the human body and evolving it to a form that can block a molecule involved in blood vessel growth and inflammation.

Research leader, Professor Nick Brindle, said the theory behind this new technique is not new, but it has been difficult to develop it for the number of complex proteins required to create more targeted drugs – until now.

Mr Brindle claimed it was a bonus that the team were able to develop the protein – known as a ligand-trap – as it targets a molecule that is involved in "a whole range of health problems".

It is hoped the process can be used to tackle heart disease, inflammation and other illnesses.

"In addition to medicine, these specifically evolved 'designer proteins' have a wide range of applications in the chemical, pharmaceutical and agricultural industries," he remarked.

"This is a big step forward. We are hoping that, over the next five years or so, this new protein can be developed into a form that could be used to treat inflammation and other conditions."

Heart disease is still one of the biggest killers in the UK, so any treatment that can improve survival rates will be welcomed by medical professionals.

According to figures compiled by the British Heart Foundation, around one in six men die from coronary heart disease, while the same can be said of one in nine women.

Approximately 74,000 people die from this condition in the UK every year – an average of 200 deaths every day.

Are stubborn managers making HR’s job harder?

Maintaining high levels of employee engagement is one of the biggest challenges facing HR professionals heading into 2014, but are stubborn managers making this task much more difficult? 

A new survey conducted by The Forum Corporation found many workers are peeved that their bosses will not apologise when they make mistakes. 

Just five per cent of respondents in Britain said their manager always or often admitted to their errors. This figure fell to a mere three per cent in the Europe, Middle East and Africa (EMEA) region.

Around 60 per cent of UK bosses insisted they always say sorry when they are wrong, but employees clearly disagree with this. 

The study also discovered that 71 per cent of managers do not ask for forgiveness because they are afraid of being labelled as incompetent, while 29 per cent suggested they did not want to look weak.

While this may seem a trivial matter to many people, leaders at The Forum Corporation believe it could have a damaging impact on employee engagement levels – something that HR specialists will be particularly wary of. 

An overwhelming 93 per cent of the respondents claimed that being able to trust their boss was very important. 

Graham Scrivener, managing director of Forum EMEA, commented: "When managers aren't transparent in their actions – and that includes accepting responsibility for errors, being truthful with their employees and acknowledging hard work – that tends to breed mistrust among employees."

HR departments spend a great deal of time attempting to establish stronger links between employees and their supervisors and this hard work could be undone if managers are too stubborn. 

A recent report by the Chartered Institute of Personnel & Development showed that employees are now becoming more upwardly mobile, as job loss fears have started to subside. 

With the economy continuing to recover, companies will find it harder to keep hold of their most talented workers, which is why it is crucial that employees remain happy and motivated in their current roles.

Scientists to benefit from new cancer database

Scientists looking for new cancer treatments will soon be able to take advantage of a new database.

The CanSAR system will make 1.7 billion experimental results available to researchers in one easy-to-access location. Special technology will also be used to try to predict potential targets for anti-cancer drugs in the future. 

One of the main benefits of the scheme is that it will let scientists from different countries work together almost seamlessly, as they can share the same information regardless of their location. 

Nell Barrie, senior science information manager at Cancer Research UK's, which has funded the system, said: "The clues we need to tackle cancer are hidden in data like this and by making it freely available we can boost our progress and make breakthroughs sooner." 

The development is comfortably the biggest disease database of its kind in the world. To put its size into perspective, it is capable of holding more information than the Hubble space telescope would gather in a million years of use.

There are more than 200 different types of cancer, each with a specific set of causes, symptoms and treatments, and so this database has the potential to revolutionise research and development. 

Dr Bissan Al-Lazikani, team leader at The Institute of Cancer Research, London, stated the database "can spot opportunities for future cancer treatments that no human eye could be expected to see". 

Advances in DNA sequencing have made the development possible, while information will also be available on nearly one million testable drugs and over a thousand types of cancer cell.

A smaller-scale prototype was previously launched and it attracted some 26,000 users in over 70 countries. Thanks to the scheme, 46 previously overlooked drug treatment possibilities for cancer molecules were discovered.

Professor Paul Workman, deputy chief executive of The Institute of Cancer Research, said: "This is an extraordinary time for cancer research, as advances in scientific techniques open up new possibilities and generate unprecedented amounts of data."

New technology helps scientists assess ‘junk DNA’

Scientists have made a significant breakthrough that enables them to analyse an entire genome for the first time, which in turn means they can discover the cause of a genetic disease dubbed 'junk DNA'.
 
Teams led by the University of Exeter Medical School and Imperial College London carried out a comprehensive study that found junk DNA is most commonly the result of mutations that occur in a newly identified gene element in a particularly remote part of the genome.
 
Thanks to the latest advances in genetic sequencing, this part of the genome can now be explored for the first time.
 
Results from the study were published in Nature Genetics and the experts behind the research discovered the condition is the result of mutations in genomic dark matter. This dark matter is made up of the large stretches of DNA that contain no genes and make up about 99 per cent of a human's genome.
 
Instead of holding genes, this dark matter is responsible for making sure that genes are "switched on" at the right times and in the part of the body where they are required.
 
Of particular interest is the fact that it was only the recent development of advanced genetic sequencing laboratory technology that made the study and subsequent findings possible.
 
Dr Mike Weedon, lead researcher and senior lecturer at the University of Exeter Medical School, said: "This breakthrough delves into the dark matter of the genome, which until recently, was very difficult to systematically study. 

"Now, advances in DNA sequencing technology mean we have the tools to explore these non-protein coding regions far more thoroughly and we are finding it has a significant impact on development and disease."
 
A host of bodies came together to fund the project to ensure the study could go ahead. These included the Wellcome Trust, the National Institute for Health Research Exeter Clinical Research Facility and the European Community's Seventh Framework Programme.

HR ‘is at an inflection point’

Chief executive officer at the Chartered Institute of Personnel & Development (CIPD) Peter Cheese believes the HR industry is at a crossroads.

Ahead of the organisation's annual conference, he stated that the world of business is transforming, mainly because of the huge impact the economic crisis has had on companies across the globe.

Mr Cheese outlined some of the challenges facing HR departments in 2013.

These include: "How to restore trust; build employee engagement; tackle skills shortages and help solve economic and societal problems like youth unemployment and issues surrounding fairness in pay and reward."

Such problems, Mr Cheese added, will not be solved with a quick fix, which is why HR professionals might need to change the way they do things.

The CIPD has launched a new framework for HR and people development and the body believes this could help businesses to thrive.

"Our framework positions HR and people development as better focused on understanding and adding value, with insight on the trends that are shaping the organisation of the future," Mr Cheese added.

One issue that some HR specialists are finding hard to deal with is big data. 

In a separate report, the CIPD stated that companies have a great opportunity to use big data to make more informed decisions throughout their business, especially during the recruitment process. 

However, many HR departments are reluctant to utilise the reams of information that falls into their laps every single day because of fears surrounding data sharing processes and a lack of capability. 

A lot of firms are currently being held back because their employees lack analytical skills. This is something that HR professionals will need to address as a matter of urgency in the coming years.

Head of CIPD Scotland John McGurk said HR's people analytics ability is "patchy" and even those few companies that are using big data for hiring purposes are failing to make the most of its huge potential. 

He added that plenty of organisations are still sceptical about the benefits of using big data.

Report calls for more advanced diagnostics technology

There have been some outstanding breakthroughs in the development of diagnostics technology on a global scale in recent years.

However, an organisation in the US believes that more needs to be done to equip doctors and hospitals with more advanced systems that make it easier for them to prescribe more effective treatments.

The Infectious Diseases Society of America believes there is an "urgent need" for tests that are not only easy for doctors to use, but also identify the bug causing somebody to feel unwell much faster.

Published in a special supplement to the journal Clinical Infectious Diseases, the report indicated that supplies of antibiotics are being wasted because people are being misdiagnosed. 

Lead author of the paper Angela Caliendo explained why it is important for consultants to get to the root cause of an illness as quickly as possible. 

"Delayed diagnosis puts us at an immediate disadvantage against infections," Ms Caliendo commented. 

"Not only is this detrimental for patients and their doctors, it also contributes to unnecessary healthcare costs through unneeded treatments, hospitalisations and isolation of patients."

She used the example of patients who visit their GP with acute upper respiratory infections to demonstrate that the current system could be failing. 

Around half of the people with this problem are prescribed antibiotics, even though most of these infections are viral and are not cured by this kind of treatment. 

The introduction of more sophisticated diagnostics technology could prevent this from happening, Ms Caliendo believes.

"It is critical that we not only invest in the development of new diagnostic tests, but that we also work to ensure these new tests are fully integrated into patient care," she added.

The UK introduced new legislation in 2010 in order to better control the risk of infection and contamination in humans. 

Food poisoning and infectious bloody diarrhoea are perhaps the two most common forms of infectious illnesses reported in the UK, while a small number of people have also been affected by the potentially fatal Legionnaires' disease in the past few years.

HR ‘crucial to success of company partnerships’

Solid HR processes and structures are crucial if strategic partnerships between different companies are to prove effective.

This is according to the Chartered Institute of Personnel & Development (CIPD), which has published new research ahead of its Annual Conference and Exhibition. 

The organisation stated that the number of businesses looking to cement a formal relationship with another company has risen sharply in recent years. However, many of these deals result in failure and the CIPD thinks HR departments must carry some of the blame for this. 

HR professionals have a lot to deal with at the moment, with hiring patterns changing and skills gaps emerging, so it is understandable that a lot of partnerships have fallen by the wayside. 

CIPD research adviser and co-author of this latest study Dr Jill Miller said that HR departments are not only responsible for handling employee issues in their own business, they must now work alongside a partnering organisation. 

Unsurprisingly, this can cause complications. 

"HR needs to ensure they recruit and develop the right people to become leaders who are able to balance the competing demands placed on them from their 'home' organisation with the goals of the network, and who will set the appropriate behavioural standards for the network," Ms Miller remarked. 

Paul Sparrow – professor of international human resource management at Lancaster University Management School – has identified three key areas that HR professionals need to focus on. These are managing risk and opportunity, improving learning and knowledge-sharing practices and governance. 

With more and more businesses entering into strategic partnerships, Mr Sparrow said that supporting such arrangements must become a "core HR capability". 

"Governance needs to be built into the design of partnerships rather than something we all talk about after the failure," he commented. 

The CIPD is now conducting even more extensive research into business agreements and the challenges facing HR departments. The results are expected to be published in 2014 and will give firms a better idea of what is required to make a success out of these partnerships.
