Energy drinks may cause high blood pressure and potentially lethal heart problems, new research has found.
Doctors are warning people with high blood pressure to 'use caution and judgment' before downing the drinks, after finding they may increase blood pressure and disturb the heart's natural rhythm.

American researchers analysed data from seven previously published studies to determine how consuming energy drinks might impact heart health.

The pooled studies included healthy patients, aged 18 to 45.

In the first part of the pooled analysis, the researchers examine
d the QT interval - a segment of the heart's rhythm - of 93 people who had just consumed one to three cans of energy drinks.

They found that the QT interval was 10 milliseconds longer for those who had consumed the energy drinks.
The QT interval describes a segment of the heart's rhythm on an electrocardiogram; when prolonged, it can cause serious irregular heartbeats or sudden cardiac death.

Lead author Doctor Sachin Shah, assistant professor at University of the Pacific in the United States, said: 'Doctors are generally concerned if patients experience an additional 30 milliseconds in their QT interval from baseline.

'QT prolongation is associated with life-threatening arrhythmias. The finding that energy drinks could prolong the QT, in light of the reports of sudden cardiac death, warrants further investigation.'

The researchers also found that the systolic blood pressure, the top number in a blood pressure reading, increased an average of 3.5 points in a pool of 132 participants.

Doctors have warned the drinks may disturb the heart's natural rhythm

 

Dr Shah added: 'The correlation between energy drinks and increased systolic blood pressure is convincing and concerning, and more studies are needed to assess the impact on the heart rhythm.

'Patients with high blood pressures or long QT syndrome should use caution and judgment before consuming an energy drink.

'Since energy drinks also contain caffeine, people who do not normally drink much caffeine might have an exaggerated increase in blood pressure.

'People with health concerns or those who are older might have more heart-related side effects from energy drinks.'

The findings were presented at the American Heart Association's Epidemiology and Prevention conference.

High consumption of processed meat.....

Processed meat 'is to blame for one in 30 deaths': Scientists say a rasher of cheap bacon a day is harmful

• Analysis of diets of 500,000 linked meat to cancer and heart disease deaths
• Should be 'limit of no more than 20g a day of processed meat', equal to one rasher of cheap bacon or one full English breakfast a week

Meals containing too much processed meat such as cheap ham, bacon and sausages could send you to an early grave, a large-scale study has found.

Analysis of the diets and medical history of almost half a million men and women linked processed meat to deaths from cancer and heart disease.

The Europe-wide research, including work by Oxbridge scientists, found that processed meat is to blame for about one in 30 deaths.
The researchers suggested a limit of no more than 20g a day of processed meat – equal to one rasher of cheap bacon.

The warning comes in the wake of the horsemeat scandal which has caused many consumers to question the origins of their food.

Processed meat, made by combining the leftover parts of animals which cannot be sold as good cuts such as steaks and joints, contains high concentrations of fat, including artery-clogging cholesterol.

The researchers from ten European countries quizzed almost 450,000 people, many of them Britons, and tracked their health for an average of 13 years.

They said: ‘Men and women with a high consumption of processed meat are at increased risk of early death, particularly due to cardiovascular diseases but also cancer.’
Some 26,344 of the participants died over the course of the study, with those who ate the biggest amounts of processed meat being 44 per cent more likely to have died than those who ate the lowest amounts.

The figures for heart disease were striking – those who ate the most processed meat, more than 160g or three sausages a day, were 72 per cent more likely to die of heart disease.



 

Processed meat such as bacon and sausages could send you to an early grave, a large-scale study has found

A study last year found that eating 50g of processed meat a day – the equivalent of one sausage or three rashers of bacon – raises the likelihood of cancer by a fifth.

But in the latest, much bigger study, those who ate the most processed meat were almost 50 per cent more likely to suffer an early death, with heart disease the overwhelming cause.

The study, published in the journal BMC Medicine, concluded that a limit of 20g a day of processed meat – equal to a rasher of bacon or one full English breakfast a week – would prevent about 20,000 early deaths in the UK each year.

Tracy Parker, a dietician at the British Heart Foundation, said: ‘With spring in the air, many of us may be looking forward to sunny barbecues. But this research suggests processed meat, such as sausages and burgers, may be linked to an increased risk of early death.

‘However, the people who ate the most processed meat in this study also made other unhealthy lifestyle choices.
‘They were found to eat less fruit and vegetables and were more likely to smoke, which may have had an impact on results.’

Professor Karol Sikora, one of Britain’s leading cancer specialists and an unpaid member of the industry-backed Meat Advisory Panel, said the key to good health is a balanced diet.

He said: ‘Don’t worry about having a bacon sandwich. It is not going to kill you. But don’t have four bacon sandwiches every day for your whole life.’

The amount of white meat eaten, such as chicken, was not linked to death rates by the researchers, while small amounts of red meat appeared beneficial.



Speaking on BBC Radio 4's Today programme, Tim Lang, professor of food policy at City University, London, said: 'This study is yet another little plank going into the edifice saying we've got to down on [processed] meat.

'This is what we're saying, let's lower the amount of animals we are producing. We need to reduce the cattle culture in this country.

'The key issue is we don't know what a good diet is, we've had dietary guidelines based on a very narrow based idea of what is nutrition.

'For me, this study is another reminder of the need to go for a more sustainable diet.'
A Department of Health spokesman said: 'It's important that everyone eats a balanced diet. Eating well and being active can help prevent serious illnesses such as cancer and heart disease later in life.

 

'Red meat can be part of a balanced diet. But people who eat a lot of red and processed meat should consider cutting down as regularly eating a lot could increase your risk of bowel cancer.

Burgers, sausages and pies were particularly singled out as being harmful

A university professor died of lung cancer aged 37 after doctors repeatedly dismissed her illness as 'purely psychological'.

Lisa Smirl, 37, saw three different doctors with a range of symptoms over a year-long period but they were dismissed as anxiety and depression.

By the time cancer was finally diagnosed it had spread throughout her body and was terminal.
Dr Smirl, who was married to a medical doctor and lived in Leeds and Brighton, kept a heartbreaking online blog about her treatment.

Misdiagnosis: Despite Lisa Smirl seeing three doctors with symptoms, her lung cancer was repeatedly written off as 'anxiety and depression'

 

 

 

Shortly after her diagnosis, she wrote: 'How is it possible that a 36-year-old, health [obsessed] conscious, occasionally social smoking, middle class, fiance of a doctor can develop metastatic lung cancer unnoticed. How?!?

'What the consultant told us was that not only was it the c-word, but that it was everywhere.

'My brain, my bones, my liver. While in some ways this was a terrible surprise, in another it was a huge relief.

• 'Talented' football striker, 27, died after suffering a fatal stroke caused by too many 'headers'
• Heartbreaking generosity of parents who gave away £22,000 raised for seriously ill daughter to help little boy they've never met walk for first time

'For the last year I'd been battling a range of bizarre and seemingly disparate symptoms that had forced me in September 2011 to go on sick leave from my job as a lecturer (assistant professor).

'The diagnosis at the time was anxiety and/or depression. And while I was both anxious and depressed, this was due to the increasingly disabling symptoms that my doctor kept insisting were purely psychological.

'So I was actually grateful for a medical diagnosis that confirmed there were objective, physical reasons behind my illness.'


Cambridge-educated Dr Smirl, who was originally from Canada, wrote how she first experienced shortness of breath and wheezing in late 2010, which was wrongly diagnosed as asthma.


  

Not psychological: Lisa Smirl said in her blog she was relieved to have a concrete diagnosis even though it was of cancer

 

 

In spring 2011, she was referred to a physiotherapist for shoulder and arm pain and started experiencing 'visual migraines' - losing her vision for half an hour - in June.

By September 2011, Dr Smirl was so sick she was forced to leave work, having been diagnosed with depression and anxiety and put on anti-depressants.

But despite a dramatic weight loss, she claimed three different family doctors refused to consider her symptoms in connection with each other.

Relief: Dr Smirl wrote a blog on her diagnosis, saying she was 'actually grateful' for a medical diagnosis that confirmed there were 'objective, physical reasons' behind her symptoms

 

 

She wrote: 'Still, despite my pleas, and a dramatic weight loss, none of my doctors (and I saw three different family practitioners) would consider my symptoms in conjunction with one another - insisting that they were all common, unrelated problems (migraines, asthma, depression, back pain).'

In November 2011, she misread her asthma prescription and took ten times the recommended amount - but the drug made no difference to a violent cough.

Her doctor finally sent her for a routine X-ray and within hours, she was given the devastating news that she had cancer.

On her blog, called Stage V - as stage IV of cancer is considered terminal - she describes her journey from 'a woman diagnosed with "anxiety" to one with metastatic cancer'.

Dr Smirl wrote: 'I can't prove it, and this is just my opinion, but I have no doubt in my own mind that my misdiagnosis was in large part due to the fact that I was a middle aged female and that my male doctors were preconceived towards a psychological rather than a physiological diagnosis.

'It is so easy to say that someone's symptoms are "anxiety" related if they are a little bit complicated, unclear or unusual. Don't repeat my mistakes.

'You know when something is wrong. Find another doctor that you connect with and who takes your concerns seriously. Get referrals. Get tested. Refuse to be dismissed.'
Dr Smirl worked in the global studies department at the University of Sussex between 2009 and 2012, but took early retirement.

Despite battling the disease, she maintained an honorary lectureship in the department until her death on February 21.
She also completed a Great North Run to raise funds for the Roy Castle Lung Cancer Foundation in November 2012.

Professor Richard Black, head of the school of global studies at the University of Sussex, led tributes.

He said: 'Lisa was a fantastic colleague and friend, a great teacher and researcher and truly inspirational in the way she dealt with her illness.'

Professor Justin Rosenberg, head of international relations, added: 'Lisa was an outstanding colleague who shared her intellectual and personal vivacity with academics and students alike.'

West Sussex PCT and the Brighton and Sussex University Hospitals Trust were unable to confirm that they were involved with Lisa's treatment.

How to lower your cholestrol....

Why looking on the bright side of life could lower your cholesterol

• Middle-aged people who are optimistic were found to have better levels of 'good' cholesterol
• Also had lower levels of triglycerides, the fatty molecules involved in hardening of the arteries
• May be due to their tendency to have a healthy body weight and a 'prudent' diet, say Harvard researchers

People with a sunny disposition are less likely to have high cholesterol, new research suggests.

Middle-aged optimists were found to have better levels of 'good' cholesterol, which has a protective effect on the heart and helps cancel out 'bad' cholesterol.
They also had lower levels of triglycerides, the fatty molecules involved in hardening of the arteries, said the researchers from the Harvard School of Public Health.

 

Be Happy: Middle-aged people who are optimistic were found to have better levels of 'good' cholesterol, which has a protective effect on the heart

 

 

Part of the reason may be due to the optimists' tendency to have a healthy body weight and a 'prudent' diet, say the researchers.

They analysed data from the Midlife in the United States study, which included phone interviews and lab tests for 990 people aged 40 to 70.

Based on the interviews, participants' levels of optimism were rated on a scale from 6 to 30 depending on their agreement or disagreement with statements such as 'in uncertain times I usually expect the best', and so on.

People with higher optimism scores also had more high-density lipoprotein (HDL) - the desirable form of cholesterol that is believed to protect against heart disease.
For every increase of five points on the optimism scale, HDL in the blood increased by one milligram per deciliter.
That same HDL increase would translated to a three per cent reduction in the risk for heart disease, the researchers said.

For comparison, regular exercise can decrease heart disease risk by six per cent.

Optimists also have higher levels of triglycerides, the fatty molecules involved in hardening of the arteries

 

But there was no connection between optimism and total cholesterol levels, or to low-density lipoproteins (LDL), the bad' cholesterol.

Lead study author Julia Boeh said: 'It is one additional piece of evidence suggesting that our psychological health and physical health are intertwined, and that viewing the world optimistically may have some tangible benefits for our health.'
Previous research by Boehm and her colleagues had shown a link between optimism and lowered heart attack risk, so they decided to look at whether there was an independent connection between optimistic or pessimistic outlooks and cholesterol, which is known to play a role in heart attack risk.
Franz Messerli, a cardiologist at St. Luke's-Roosevelt Hospital in New York, who was not involved in the study, said: 'It's still impossible to say whether optimism causes a change in cholesterol, or cholesterol influences outlook, or both are subject to some third variable.'

The Harvard researchers did try to account for other influences, and when they factored in lifestyles, including diet and alcohol consumption, and body weight - the link between optimism and blood fats became weaker.

That suggests that optimists' tendency to have healthier lifestyles and weight may explain 'in part' the differences in their blood lipids, researchers said.

Conversely, the risk of heart attack and stroke goes up in depressed people, Messerli said. 'But nobody has shown the opposite, that all of a sudden if you go from a pessimist to an optimist your risk goes down.'

Female brains are more efficient.....

Women really do have smaller brains... but they use them more efficiently than men

• Female brains are typically 8 per cent smaller
• However they are more efficient at tracking changes and inductive reasoning

It's a standing joke among many men... that women have smaller brains.

Now research seems to indicate that while this may be true, it doesn’t matter because women use their brains more efficiently.

A woman’s works more efficiently than the man’s by using less energy and fewer brain cells to achieve the same, or even better results.

 

Smaller brains, greater efficiency: Research has found that despite women having 8 per cent smaller brains this could help it perform quicker

 

 

 

It could be because while men have more of the bundles of brain cells essential for reasoning - neurons - the women have more connections between theirs, enabling quicker thinking despite having less grey matter.

The new research, carried out by University of California neuroscientists assisted by colleagues in Madrid, set out to question why women, with brains typically 8 per cent small than those of men, were of equal intelligence.

It focused on the section of the brain known as the hippocampus - vital for a useful memory and emotions.

More...

• Why do women take forever to pack? It's not because we are indecisive, it's because our brains are wired differently to men's (and that's not our only special quirk...)
• Why faces appear male or female... it depends on which part of our brain is analysing them

In men, the larger the hippocampus, and the more neurons, the higher the intelligence.

But the researchers found that in women, a larger hippocampus, typically of course smaller than men’s, was no indication of greater intelligence - and even suggested that the smaller the hippocampus, the better.

The scientists carried out psychological tests on 59 women and 45 men aged from 18 to 27.

In line with previous studies they found the women were better at inductive reasoning and tracking a changing situation, while the men showed greater prowess at spatial reasoning.

 

Brain power: Men showed greater prowess at spatial reasoning, but fell behind women on inductive reasoning and tracking changing situations

 

But the women’s brains were the more efficient, suggested the published results of the research, published in the scientific journal Intelligence.

The paper concluded: ‘At this structural level, females might show greater efficiency requiring less neural material for achieving behavioural results on a par with males.’
 
Cambridge University professor of Trevor Robbins said the research was fascinating but required further examination.

Prof Robbins said: ‘The research suggests that, in women, the smaller the hippocampus, the better it works. The size of a structure doesn’t necessarily bear any relation to how well it performs.

‘The smaller size could represent more intense packing of nerve cells or more active signalling between them, meaning they are operating more efficiently.’
