New studies reveal why running won’t damage your knees

RUNNING SCIENCE

YOUR excuse for not wishing to run or jog may have just been debunked.

Experts say running is not actually bad for the knees – a view held by many who love to pound the pavements.

Studies show there is no link between running and osteoarthritis, and the exercise may even strengthen cartilage.

A new book entitled Running Science says, “couch potatoes” have around a 45 per cent greater risk of osteoarthritis compared to those who run.

It states that runners place eight times their body weight on to each leg with every step.

Although that is three times as much as when walking, we take wider strides when running, so there is reduced contact time with the ground.

This means the pressure on the knees is broadly similar.

The book’s consultant editor, Professor John Brewer, of St Mary’s University in London, said runners should increase intensity of the exercise gradually, wear the right shoes and run on different terrains.

He said: “The human body is designed to run… although the knees will be under stress when running, the body will adapt to this stress and develop cartilage, muscles, tendons and ligaments that are stronger as a result of running – protecting the knee rather than damaging it.”

Osteoarthritis of the Knee.

Running Science, published last week, says that damage to joints is a “common excuse” for not running.

However, a chapter written by independent physiotherapist Anna Barnsley states: “The good news is that the converse appears to be true.”

She cites studies showing that although runners develop bony growths in their knees, there is no evidence of narrowing of the joint space, which would indicate degeneration.

The agony of osteoarthritis is caused when cartilage is no longer there to cushion the joints from the impact of walking or other exercise.

However, the book states that regular running probably increases the amount of this natural protection.

That could be because exercise helps people lose fat, which can damage cartilage.

Running also prompts blood flow and cell regeneration in the knees.

The advice follows a study by Baylor College of Medicine in the United States, which analysed knee X-rays of 2,683 participants.

The study found that 22.8 per cent of those who had been runners had signs of knee osteoarthritis, compared to 29.8 per cent of non-runners.

Running Science also noted that runners may have a genetic predisposition to osteoarthritis – meaning exercise is not necessarily to blame.

IT systems in the NHS are pitifully weak. It must get on top of cyber-crime

RANSOMWARE

Ransomware

The message that appears if encryption occurs.

Two days ago, the NHS was hit by a major cyber-attack using ransomware. Computer screens suddenly announced that files and data were unavailable unless the user paid a fee. In some Health Board Trusts, phones stopped working, too; patients were advised not to go to A&E, and the full effect of this attack will not be known until this week when many employees may find that their computers will not function. The virus is worming its way through networks that could yet reap much more havoc. While state organisations like the NHS have many questions to answer, including the pitiful support they have given to their IT systems – including the running of out-of-support Windows XP systems – holding the nation’s healthcare hostage in this way is an unconscionable criminal act. It is also a wake-up call to the British state. Our newfound reliance upon electronic communications leaves the country vulnerable to extortion.

Of course, it is important to keep pace with technological change, especially if it promises to save money and streamline record keeping. But putting so many eggs in one basket does incur risk – and there have been many warnings before now that the NHS is struggling to keep things in good order. Last month, Barts Health, England’s largest trust, had to cancel at least 136 operations and “hundreds” of chemotherapy sessions after its IT systems went down; it also suffered a ransomware attack in January. It is feared that some trusts are continuing to use outdated software that might be more exposed to attack.

This is why patients have often expressed nervousness about the reliance upon NHS databases, particularly the notion of a national one. No matter how many assurances are made to the public that such arrangements are airtight, the criminals always seem to find a way to get in. The solution is obviously to tighten security; equally it is imperative that users take care – a system is only as strong as its most fallible point. Either way, it is now up to the security services to act and act fast. Cyber-crime – which has previously hit companies such as TalkTalk – costs the economy billions and puts lives at risk. The Government has to get on top of it. It has failed in its duty of care by taking necessary measures in protecting the most sensitive of information.

Theresa May pledges an overhaul of the Mental Health Act

BRITAIN

MHA 1983

The prime minister, Theresa May, has announced that the Mental Health Act 1983 will be overhauled if the Conservative Party win the General Election on 8 June.

Prime Minister Theresa May has promised the biggest shake-up of mental health provision for 30 years if re-elected to tackle the “burning injustice” of current treatment.

In a major policy announcement before the General Election next month, the Conservative leader has pledged to scrap the “flawed” 1983 Mental Health Act after concluding it is “unfit for purpose”.

A string of policies designed to end discrimination in mental health treatment and make provision suitable for the 21st century will be implemented instead.

Ten thousand more NHS staff will be assigned to mental health work in the next three years to boost treatment under the Tory plans.

A teacher in every primary and secondary school will be trained in mental health first aid to identify signs that children are developing anxiety or depression.

Discrimination laws will be toughened up to protect employees with mental health issues while Samaritans charity helpline will be Government funded until 2022.

The pledges will form part of the Conservative manifesto and come after the Prime Minister named improving mental health as a key priority when she took office.

Mrs May said: “On my first day in Downing Street last July, I described shortfalls in mental health services as one of the burning injustices in our country.

“It is abundantly clear to me that the discriminatory use of a law passed more than three decades ago is a key part of the reason for this.

“So today I am pledging to rip up the 1983 Act and introduce in its place a new law which finally confronts the discrimination and unnecessary detention that takes place too often.”

The Act was written at a time when mental health issues did not have the same level of understanding or prominence in public debate as today.

The legislation has been criticised by campaigners after the number of detentions under the Act increased by 43 per cent in the last decade.

There are also concerns the law is fuelling discrimination. In 2014-15, close to 60 per cent of black people in hospital with mental illness were detained – compared to around 40 per cent for white people.

In a recent report the Care Quality Commission, the independent regulator of healthcare services, strongly criticised the legislation.

It said the Act “may disempower patients, prevent people from exercising legal rights, and ultimately impede recovery or even amount to unlawful and unethical practice”.

Part of the problem, according to Tory sources, is that mental health case law built up over the years is all based on the old legislation.

Therefore, Mrs May will repeal the Act and bring forward a Mental Health Treatment Bill in its place.

Schools and hospitals will also see changes under the Tory plans. Ten thousand extra workers will be put on mental health provision in the NHS.

It remains unclear whether all the places will be new hires or current workers already employed by the NHS.

Sources insist no new funding is needed for the scheme because money has been carved out of the current Health Department budget.

However, campaigners are likely to criticise the failure to promise billions of extra spending on mental health that they have demanded.

The Tories’ wider plan for NHS spending will be published in the manifesto later this month.

The additional mental health training is to be provided by a charity within the Third Sector and will cost the Government £2 million.

The courses, described as “comprehensive” by Tory sources, will equip teachers to spot developing mental health issues in children and tackle psychotic episodes.
