Donie's Ireland daily news BLOG Sunday

Irish people pay more for food and drink than the rest of Europe

 

Irish people pay more to eat, drink and smoke than nearly everyone else in Europe.

And for some staples such as fruit, vegetables and potatoes we’re paying a whopping 38pc more than everyone else.
Overall, the price of food and non-alcoholic beverages in Ireland was 18pc more expensive than the European Union average in 2012, a new Eurostat survey shows.
Alcohol prices here are 62pc higher than average and cigarettes are twice as dear – making them the most expensive in the whole EU.
Ireland was the fifth most expensive country in the EU for foodstuffs, with milk, meat and bread all well above average.
And the price gap has widened since 2011 when it stood at 17pc.
The survey found that Denmark was the most expensive EU country with prices 43pc higher than average, followed by Sweden, Austria, Finland and Ireland.
The survey is based on a basket of 500 comparable products across EU member states and 12 other countries outside the EU such as Turkey and Norway.
For alcohol, Irish prices were double those in cheapest Bulgaria, Romania and Germany.
And for cigarettes, Irish consumers pay 99pc more than average – four times as much as in Hungary, Lithuania and Bulgaria – and eight times as much as the cheapest, Macedonia.
Even though we’re a huge producer and exporter of dairy products, the price of milk, cheese and eggs here is 19pc above average.
CHEAPEST
And for meat – which we also produce in abundance and export across Europe – prices are 10pc higher than in our nearest neighbour, Britain, whose prices are bang on the average for the EU.
Norway is by far the most expensive country to shop in, with the price of food a massive 86pc higher than in any other country in Europe, while alcohol and cigarettes are prohibitively priced at three times the EU average.
Macedonia is the cheapest country in Europe, with food prices 58pc and tobacco 25pc of the EU average.
Of our favourite holiday destinations, Spain is one of the cheapest, with most products around 10pc cheaper than average, but food prices in Italy and France are both around 10pc above the norm.
And though prices in Britain have increased in recent years they’re still much cheaper than ours coming in at 4pc above the EU average.
Ibec’s Retail Ireland director Stephen Lynam said alcohol and tobacco prices were higher because of government tax, while for foodstuffs the price gap reflected the higher cost of doing business here.
“For example, labour costs are 17pc higher than in Britain and electricity costs are 18pc higher and there are also economies of scale in other countries,” he said.
While Ireland was a big producer of meat and dairy products, high labour costs to process and handle these products resulted in prices being higher, he said.

Nelson Mandela health now reported as in a critical condition

  

NELSON MANDELA’S HEALTH HAS DETERIORATED AND HE IS IN CRITICAL CONDITION, THE SOUTH AFRICAN GOVERNMENT SAID THIS SUNDAY.

The office of President Jacob Zuma said that the president had visited the Mandela, the former president of the country who was imprisoned for nearly three decades as he battled the country’s apartheid system of racial separatism, Sunday evening.
Zuma’s office said he was informed by Mandela’s doctors that his condition had become critical in the last 24 hours.
Mandela, 94, has been intensive care for more than two weeks week. He was hospitalized on June 8 for what the government said was a recurring lung infection.
Britain’s Sky News reported that Zuma and ANC Deputy President Cyril Ramaphosa visited Mandela in hospital Sunday.
Zuma said in a statement: “The doctors are doing everything possible to get his condition to improve and are ensuring that Madiba is well-looked after and is comfortable. He is in good hands.”
Madiba is Mandela’s tribal nickname. He turns 95 on July 18.
Mandela became South Africa’s first black president after the end of apartheid in 1994.

Does the continuing use of mobile phones increase our risk of cancer?

   

The mobile goes everywhere with her, and I literally have to prise it out of her hands at bed time. I must admit, I am also very fond of my iPhone. I can’t imagine how I survived so long without one. 

“Mum, will you get off your phone,” my children will shout. And yes, because of my job and organising their social lives, it can feel like it is permanently attached to my ear. Should I worry?
Well, yes, as according to some scientists my constant use could put me at a higher risk of developing a brain tumour or some other form of cancer.
I can still remember the first mobile phone I ever used. It was Saturday, Mar 31, 1990, and I had been asked by my then newspaper, The Independent on Sunday, to cover a demonstration against the poll tax in London.
“Here take the office phone,” my editor shouted at me as I walked out the door.
It was the size of a brick, it was very heavy to carry, with a large aerial, and ran out of battery within 15 minutes. When the demonstrators began to riot, I had to file copy from a phone box.
In 1996, Neil Whitfield, a father of six from Wigan, was promoted to sales manager and was given his first mobile phone by the company. “My job required me to use it heavily and after a few months of getting the phone I had to visit my GP as I was suffering from severe headaches,” he recalls.
“The doctor advised me that they were probably caused by driving long distances for work and to take painkillers. The headaches persisted, accompanied by fatigue and memory loss. When my hearing started to deteriorate in my left ear, I went for tests.”
Unfortunately, the neurologist discovered a tumour in Whitfield’s brain, just behind his left ear, the side he held his mobile phone on.
“The specialist asked if I had ever used a mobile phone and when I said; ‘Yes,’ he replied that the mobiles might be ‘the smoking of the 21st century.” I was given five years to live without surgery so underwent a nine-hour operation,” he says. Now completely deaf in his left ear, which affects his balance, Whitfield, 56, still gets headaches and facial twitches. All, he believes, thanks to his Nokia mobile phone. “I am angry that they don’t warn the public,” he says.
So should we be worried about our mobile phone usage ? Are they killing us ? The argument has already lasted over 20 years so what is the truth?
Will we ever find out — or, if we do will it be too late ?
The most comprehensive study was complied in 2011 by the International Agency For Research on Cancer (IARC), which is part of the World Health Organisation, after listening to over 30 experts and reviewing all the evidence and data, they decided to reclassify radiation from category 3, with “no conclusive evidence” of causing cancer, to a Group 2B a “possible human carcinogen.”
Dr Timothy Moynihan, a medical oncologist with the Mayo Clinic in Florida, believes that more research is needed to prove a link.
“It often takes many years between the use of a cancer-causing agent, like tobacco, and the observation of an increase in cancer rates. At this point, it is possible that too little time has passed to detect an increase in cancer rates directly attributable to cellphone use,” he explains.
“The bottom line? For now no one knows if cellphones are capable of causing cancer. Although long-term studies are ongoing, to date there is no convincing evidence that cellphone use increases the risk of cancer.”
But Dr Jack Philips, a neurosurgeon for over 30 years at the Beaumont hospital, Dublin, suggests if there was a link, neurologists around the world would have already seen a marked increase in the incidence of brain cancer, especially in countries like America, where the usage of mobile phones is so high.
“Yet we haven’t,” he says. “The incidence of brain tumours has not increased at all in the 30 years I have been practising, and you can quote me on that. We normally see about 80 people with malignant tumours each year.
“I would have expected to see a change. Like always there are contrary reports, some may be based upon poor research or subjective research, which are not objective. The neurologists that I have spoken to feel that the emissions from phones have not led to brain cancer.”
In 2000, Dr Philips was part of a team at Beaumont hospital investigating a link between 73 of their patients suffering from glioma (the most common type of malignant brain tumour) and which hand they held their mobile phone in.
“We believed if there was a link the patient would get the tumour on the side of the head they held their phone too. We didn’t find any side dominant, we found often they had the tumours on the opposite side that they used the phone. Most people hold the phone in their right hand and there has not been a change in the dominance in all of these years,” he explains.
Dr Philips also points out that most of the “alarming” scientific reports tend to focus on the effect of mobile phones on children.
“They argue that the immature brain will be affected by them. The neurologist and paediatricians at Beaumont hospital meet every week, and there has never been a case in 30 years of a child presenting with cancer because of the use of mobile phones. So for me it doesn’t hold water,” he says.
The Irish Cancer Society also agrees that to date the research is “inconclusive’, but suggests more needs to be done to explore the linkage.
Dr Sinead Walsh, the research manager at the ICS, says people should be aware of the “possible risk” until it can be proved otherwise.
“Many studies around the world have found no evidence of an increased risk of cancer due to mobiles, but we cannot yet be sure about the long-term effects of their use,” she explains.
“The Irish Cancer Society recommends that until more conclusive information becomes available people are advised to limit exposure to the potential harm by keeping calls short, using hand free devices or texting.”
No doubt this debate will continue for many years to come, but as for me? Well, my mobile phone is essential for work and keeping track of my children’s hectic lives. But maybe I’ll stop charging it up, next to me as I sleep. And perhaps I will listen more to my children when they shout; “Get off the phone, mum!” At least my monthly bill will be cheaper.

The lack of Physical Education in Irish schools damages students health

    

THE LOW LEVELS OF PHYSICAL ACTIVITY IN IRISH SCHOOLS MAY GET EVEN LOWER.

In 2009, Professor Thom McKenzie wrote that “school physical education was the pill not taken”. This seems to be the case in Ireland with recent worrying developments in the provision of physical education.

A new framework for the Junior Certificate has been devised by the National Council for Curriculum and Assessment, and will be implemented in September. The framework provides an innovative way of looking at education in our secondary schools. Key features of the framework include project work, ongoing assessment and increased autonomy for schools, allowing them to design and deliver a curriculum to suit their students’ needs.
However, in the process of developing this framework, physical education (PE) has somehow fallen through the cracks.
The new Junior Certificate proposes the delivery of 100 hours of PE over a two-year period in the form of a ‘PE Short Course’. This move allocates less time to PE. In the majority of cases schools offer a double class (or two single classes) of PE per week over a three-year period at Junior Cycle level. This equates to 147 hours. The change means a potential decrease of almost one third in the time students aged between 12 and 16 will spend learning physical education.
This lack of provision for PE is worrying, and when reflecting upon European figures, it becomes clear that the health and well-being of students may not have been considered when this new Junior Certificate framework was designed.
Eurydice, the network responsible for providing information on, and analyses of European education systems and policies in 36 countries, published a comprehensive analysis of Physical Education in schools in March. The report positioned Ireland third from last in Europe. When compared to our counterparts, Ireland offers 1.2 hours of PE per week, as opposed to France (2.8), Portugal (2.8), Hungary (2.4), Germany (2.2) and the UK (2). For a country that prides itself on its education system, this is an uncharacteristic shortcoming.
It is these international figures that make the recent developments in education so baffling. Given our standing in Europe, it might be expected that the NCCA would make a sincere effort to increase the provision for PE in schools. However, contrary to all international trends where the health and well-being of the student is becoming more central to the education process, Ireland is instead cutting the time allocation to PE by almost one third.
The implications of this on today’s teenagers are compelling. Clearly, it will exacerbate an already dire situation:
* Three out of every four Irish adults and four out of five Irish children do not meet the Department of Health and Children’s National Physical Activity Guidelines (CSPPA, 2010).
* The CSPPA report also showed that one in four children is unfit, overweight or obese and had elevated blood pressure.
* In 2012, The Lancet medical journal reported that in the Republic of Ireland, 53.2 per cent of the population do insufficient exercise.
* Physical inactivity is the main cause for approximately 21-25 per cent of breast and colon cancers, 27 per cent of diabetes and 30 per cent of ischemic heart disease burden in the EU (World Health Organisation, 2013).
* Ninety per cent of people with diabetes have type-two diabetes, which is largely the result of excess body weight and inactivity. In Ireland, over a 12-month period in 1999/2000, the health care costs for treating the condition were estimated at €580.2m. This equated to 10 per cent of the total health expenditure, but it is expected that this will increase to 25per cent by 2040.
When designing and implementing education policy the student must be at the centre of all considerations. In a society where the problem of obesity is foremost in the minds of all citizens and physical activity levels are at an all-time low, physical education must be part of the solution.
PE alone will not save our teenagers (who will live shorter lives because of this physical inactivity and lack of access to PE), but it is one vital cog in the wheel if we are to turn current trends around and reverse childhood obesity, increase activity levels and develop a culture of healthy living.
PE is taught by highly educated teachers who engage in professional development to keep up to date with new teaching and learning techniques. Gone is the day of the science teacher/GAA coach taking a class out to PE with his tracksuit pants tucked into his Doc Martins. With three universities now graduating 180 PE teachers each year, there has never been so many highly qualified and enthusiastic teachers to deliver a balanced curriculum. Dance, gymnastics, orienteering, health studies, functional movement, diet and lifestyle, field games and team challenges are but a few of the areas covered in a modern-day PE class.
The focus now is to prepare our students for a lifelong involvement in physical activity through exposure to a wide range of sporting genres, and more importantly to educate our students on what it is to be healthy, fit and active. Only then can they be competent participants in physical activity.
In a time when PE has never been more essential in terms of physical, social and emotional wellbeing, as well as the proven positive impact on mental health, why is the NCCA cutting the time allocation for the subject? Our students need PE. They need exposure to a variety of sporting and physical activity endeavours. They need an opportunity to develop the physical movement skills necessary to participate, and our society needs a better understanding of what it is to live a healthy and active lifestyle. Physical Education in Irish secondary schools is truly in a perilous position.
Currently, there are some excellent initiatives being developed in the area of health and physical activity. Dr Stephanie O’Keeffe and the Department of Health have just launched a Healthy Ireland Strategy 2013-2025, Senator Eamonn Coghlan has been leading a programme called the ‘Points for Life Initiative’ to improve physical activity levels in primary schools, and a new cross-border initiative, All Island All Active, launched by Dr Fiona Chambers and Prof Deirdre Brennan which aims to increase activity levels to three in five citizens by 2025. However, PE in our secondary schools has been overlooked.
It is time for the Government to take responsibility for the well-being of students in their teenage years.

Doctors issue Ramadan advice to Diabetic Muslims

   

Experts have warned that Muslims with diabetes who choose to fast during Ramadan may be putting their health at risk.

More than 191,380 people in Ireland currently have diabetes – equating to 6.1% of the population. As of the most recent census, the Central Statistics Office (CSO) estimates there to be 49,204 Muslims in Ireland
A figure that shows a sharp increase over the previous five years. Ireland’s Muslim population included 8,322 primary school aged children and 3,582 of secondary school age – among whom diabetes is also on the increase.
Many Muslims with diabetes may choose to fast during Ramadan, which takes place from July 9th to August 7th this year, abstaining from eating, drinking and using oral medications from dawn to sunset, despite guideline recommendations for the management of diabetes during this time.
For people with type 2 diabetes, this decrease in food intake along with changes to medication means they risk hypoglycaemia (low blood sugar) which, if left untreated, can lead to serious medical problems including loss of consciousness, convulsions or seizures.
“Prolonged fasting poses health risks for people with diabetes especially when undertaken without medical guidance. Despite this, Diabetes Ireland is aware that many do fast for religious or personal reasons and as a consequence may develop acute complications.” said Dr Anna Clarke, Health Promotion and Research Manager with Diabetes Ireland.
“It’s important that healthcare professionals discuss fasting and dieting with people with Type 2 diabetes at diagnosis and on an ongoing basis. This is practically challenging for Muslims who take medication to manage their diabetes and this year given that Ramadan is falling over the summertime with longer daylight hours, it is vital that patients and their GPs plan ahead and discuss any necessary changes to treatment at least two months before Ramadan.” she continued.

Does a Super-moon have a super effect on us earth people

  

The term super-moon denotes a full moon that occurs at roughly the same time the moon is nearest Earth in its monthly orbit.

An astrologer, not an astronomer, coined the term super-moon, and it has only recent come into common usage.

Although this term is of little to no importance in astronomy, its significance to astrologers may be greater, and some may suppose that a super-moon has some kind of effect on people on Earth. But does it? I decided to calculate the values of different influences on individuals at the extreme of lunar perigee (when the moon is closest to Earth, and presumably has the greatest effect on our planet).
Astronomers use the term perigee to describe the moon’s closest point to Earth, from Greek wordsperi meaning “near” and gee meaning “Earth.” In astronomy and other sciences, a related term –perigean tides – refers to the higher tides that can occur when full moon and perigee coincide, as they fairly frequently do. Simply put, an extra-close full moon causes higher-than-usual perigean tides.
What’s more, given the change in distance between the moon’s farthest and closest points, the full moon can appear as much as 14% larger in the sky and 30% brighter to our eyes than at minimum size and brightness.
These changes do not come all of a sudden from month to month, however, and without anything with which to compare them, the changes in the moon’s size or brightness are hard to quantify by simple observation. To notice the difference, you would need to see the apogean (smallest) full moon and theperigean (largest) full moon side by side, which only possible through photography or through some form of direct measurement.
During the time of a super-moon, or any full moon, our satellite is in line with the sun. At that time, the sun and moon’s gravitational effects combine. For reasons we will not discuss here, the sun’s gravitational effect on Earth (as in influencing the tides) is only about half that of the moon. For this discussion, we will simply ignore the sun’s influence.
When the moon is closest to the Earth, its gravitational pull is at its peak.
So the question becomes, how much does the moon’s gravitational influence on Earth vary from minimum (apogee, or farthest point from the planet) to maximum (perigee)?
I will not bore you (or scare you!) with the math, but the variation from minimum lunar pull to maximum pull is roughly 23 percent. That sounds like a lot. However, it amounts to less than 2 ten-thousandths of the mass (or less precisely, the “weight”) of the moon.
More importantly from an astrological perspective (I presume, since I decidedly am not an astrologer) would be the effect on a human being. Consider an 80-kilogram (176-pound) human being. The maximum difference between apogean and perigean moons is about 73 milligrams, or about 1/14th the mass of an ordinary paper clip. If you factor in the solar gravity effect for a super-moon, or full moon closest to Earth, this effect may rise to about 110 milligrams, roughly equivalent to about 1/9th the mass of a paperclip.
In either case, the effects are imperceptible, and far smaller than those encountered in other everyday situations, such as being near a mountain or even a large building.
But, you might counter, I said earlier than an extra-close full moon causes higher-than-usual perigean tides. The tides are a very different situation from human beings. Tides work through what is called adifferential gravitational effect. Specifically, the force of gravity exerted on the part of the Earth opposite the moon (the far side of Earth, as seen from the moon) is slightly less than the force of gravity exerted on the part of the Earth directly beneath the moon (the Earth’s near side, as seen from the moon) at any given time. Why? Because there’s an additional distance – about 8,000 miles – from one side of earth to the other. The force of gravity weakens rapidly with increasing distance, producing the differential.
The result of this differential gravitational effect of the moon is that our planet is stretched slightly, along a line between the Earth and moon. The body of the Earth is fairly rigid, so it does not stretch much, but the oceans are much more easily moved. Thus the effect piles up water on either side of Earth, and these piles of water – created by the differential gravitational effect – are the tides. Note that, on average, the tidal effect is quite small. It raises tides only a few feet across an 8,000-mile-wide planet Earth.
Technically, the same effect acts on your body as well, since one side is farther from the moon than the other. However, the difference in distance is on the order of one foot, rather than thousands of miles. Thus the differential is millions of times less, and the effect on a human body infinitesimally small and irrelevant.
Super-moons are important because they focus attention on the moon, and nature in general. But the bottom line is that any physical effects of super-moons are not exactly super. There is no reasonable evidence that they cause super disasters. The effects that people may attribute to them are psychological rather than physical.
There are several super-moons this year and every year. To learn about super-moons in general try these Earth Sky posts:

Irish Government Ministers close to agreement on abortion legislation

  

Fine Gael and Labour ministers are close to finalising how to deal with a suicidal threat to a woman’s life in forthcoming abortion legislation.

It is understood the clinical assessment will be in two stages but that it will not involve six doctors.
The two parties are expected to reach agreement before Tuesday’s Cabinet meeting on the number of doctors to be involved in each stage.
The legislation will also set out the framework for terminations in medical emergencies and for medical conditions that threaten a woman’s life.
Minister for Agriculture Simon Coveney said Fine Gael is working with the Labour Party to find a compromise on abortion legislation that will command a majority in both parties.
A much clearer picture is likely to emerge at the Cabinet meeting this week, the minister said, but added that legislation should not be rushed.
He told RTE’s The Week in Politics that it could take another week to reach an agreement.
He said that he shared most the of views expressed by Minister of State Lucinda Creighton on this issue.
The Agriculture Minister confirmed that he had a number of “private conversations” with Minister for Heath James Reilly about the legislation in recent days.
Reports in today’s Sunday Independent about the views of two Labour TDs on abortion legislation were attempting “to sow division” between the Government parties, Minister Coveney said.
Minister of State at the Department of Transport, Alan Kelly, has said the secretly taped conversations with his Labour colleagues on abortion legislation “reflect their individual opinions” and will have no impact on how the Government will deal with the issue.
He said Labour was the only party that said it would legislate for the X Case in its manifesto.
The minister said the public are ahead of legislators on this issue, and it needs to be dealth with.
He said he was hopeful that the heads of the bill will be brought to Cabinet on Tuesday.
Labour TD Aodhán Ó Ríordáin has responded to the report of a secretly taped-conversation he had with a woman at his constituency office in Marino in June of last year about legislating on the abortion issue.
In a statement, Deputy O’Riordain said a recording of the meeting emerged on tape a number of months ago, adding that it took place without his consent or knowledge.
He said it was a pre-arranged appointment with a woman who presented herself as a constituent with a query about third-level fees.
Deputy O’Riordain said his views and those of the Labour Party on the X-case legislation are well known and that they are fully committed to passing legislation which was included in its pre-election manifesto.

The morning after pill should be available under medical card scheme says Irish Pharmacy Union

  

The morning after pill should be available to women under the medical card scheme, pharmacists have claimed.

A survey by the Irish Pharmacy Union (IPU) found that 18% of women with a medical card chose to get their emergency contraception from a pharmacy as opposed to getting it free on prescription from their GP.
  IPU vice-president Kathy Maher said pharmacists already offer seasonal flu vaccination services without charge to medical card patients – so a service for the morning after pill should be put in place.
“It is important to stress that this medication is for emergencies only,” Ms Maher said.
“Pharmacists offer a thorough confidential consultation with the patient before the medication can be provided.”
She added that women can get timely advice and treatment from community pharmacies since more and more are open throughout the weekend and late in the evening.
Results from the survey were announced today ahead of the IPU National Pharmacy Conference in Maynooth, Co Kildare.
Ms Maher said it was important to urge women to look after their sexual health and use precautions to avoid unwanted pregnancy.
She insisted that anyone who is concerned about their sexual health should ask a pharmacist for advice in the strictest confidence.
The IPU survey also revealed that 78% of consultations with pharmacists for the morning after pill take place within 24 hours of unprotected sex.
Some 33% of those consultations take place within 12 hours of intercourse.
Women aged 18 to 24 accounted for the majority – 47% – of consultations, followed by those aged between 25 and 30 who accounted for 23%.
Among the 18% of women with a medical card who got their emergency contraception from their pharmacy and not their doctor, 70% did so within 24 hours of unprotected sex, and 90% within 48 hours.
Monday was found to be the most common day for patient consultations, and the largest numbers were recorded in large urban areas such as Dublin and Cork.
The morning after pill was made available to patients from pharmacists without a prescription for the first time in February 2011.
Pharmacists advise it is most effective within 24 hours of having unprotected sex, but can work for up to 72 hours.

Court judgments of €44m made for creditors on over half of Irish bank account consumers

       

NEW FIGURES FROM BUSINESS AND CREDIT ANALYSTS VISION-NET SHOW THAT BANKS ACCOUNTED FOR 56PC OF THE TOTAL VALUE OF COURT JUDGMENTS AWARDED AGAINST CONSUMERS LAST MONTH.

Banks have resorted to the courts in a bid to get €23m in debts repaid in just one month, the new figures show.
The other main creditors were the Revenue Commissioners, credit unions and professional services firms which, between them, accounted for more than €13m in judgments, according to the figures.
Last month, the courts awarded more than €44m to creditors for debts unpaid by consumers and firms – the highest amount since last August.
So far this month, commercial judgments amounted to more than €19m – the highest since October 2010.
Vision-net: Vision-net’s figures show 114 Irish firms failed this month – down 16pc on last April . Of the 114, 68 were liquidated, 43 had receivers appointed, and two entered examinership.
The construction sector accounted for almost 17pc of insolvencies this month, closely followed by the wholesale and retail sector with 16pc.
Vision-net’s figures recorded 3,238 company and business start-ups this month – an increase of 16pc on last April.
But firms held 106 meetings of creditors this month, owing almost €28m.
When Vision-net stress-tested the economy, it found that 64pc of firms in the hospitality sector were at high risk of collapse, followed by construction, IT, motor, and the wholesale and retail sectors.
Vision-net’s managing director Christine Cullen said the figures showed the economy was still very fragile. “That fragility is particularly evident in the huge amount owed to banks which are increasingly going to court to have personal debts repaid.”
She said her figures only showed court judgments, so it was likely that the scale of personal debt was higher than what was officially recorded.
“As well as that, a court judgment is no guarantee of payment. It is clear that many people cannot settle their debts, so the new personal insolvency arrangements are an important intervention,” she added.

Nearly 50% of all deaths from Prostate Cancer can be reduced from a new screening type

  

A NEW DESIGN OF SCREENING COULD IMPROVE THE RATIO BETWEEN BENEFIT AND HARMS OF SCREENING TYPE.

Focusing prostate cancer testing on men at highest risk of developing the disease is likely to improve the ratio between benefits and the harms of screening, suggests a paper published this week on bmj.com.
Prostate specific antigen (PSA) screening is widely used for the early detection of prostate cancer, but remains highly controversial, as it became widespread long before evidence to prove its value. There is now evidence that PSA screening can reduce prostate cancer mortality in men who would not otherwise be screened. However, this can come at considerable harm.
As there is little evidence to support many aspects of screening guidelines, researchers from Sweden and the USA carried out a case-control study taking data from the Malmo Preventative Project (MPP) cohort, in an attempt to develop an evidence-based scheme for prostate cancer testing. A previous study from the MPP, published in the BMJ in 2010, demonstrated that PSA level at age 60 is strongly predictive of the risk of death from prostate cancer by age 85.
The Malmo cohort included 21,277 men aged 27 to 52 who participated in the MPP between 1974 and 1984. All these men gave a blood sample. A smaller group of these men were then invited to provide a second blood sample about six years later: 4922 (72%) of those re-invited complied.
The researchers focused their studies on men close to age 40, mid-to-late forties (45-49) and early-to-mid fifties (51-55).
Within 25 to 30 years, 44% of deaths from prostate cancer occurred in those with the top 10% of PSA levels at age 45-49, a PSA of about 1.5 ng / ml or more. The risk of prostate cancer death was more than 10 times greater in this group compared to men with the lowest 25% of PSA levels.
The researchers questioned whether PSA screening should start at age 40, mid-to-late 40s or early 50s: they found that even for men with PSA in the top decile at age 40, the risk of metastatic prostate cancer was very low at 0.6%, after 15 years of follow-up. The researchers say that due to this, it would be difficult to justify initiating PSA testing at age 40 for men with no other significant risk factor.
In contrast, the risk of developing metastatic prostate cancer within 15 years is close to three-fold higher for men in the top level PSA at age 45-49 (1.7%) and close to ten-fold higher at age 51-55 (5.2%). This suggests that initiating PSA screening after age 50 would leave a significant proportion of men at elevated risk of later being diagnosed with an incurable cancer.
The researchers also looked at screening intervals: results showed that the absolute risk of metastatic cancer remains very low within 15 years follow-up for men with PSA in the low deciles and as such, a screening interval less than five years for these men is unnecessary.

Parents should ask their children these four questions every day, says expert

   

A child expert Dr Claire Halsey above left has suggested mums and dads should ask their kids four questions at the end of every day.

Child psychologist Dr Claire Halsey thinks that asking questions can help improve relationships between parents and their children. The average Mum or Dad has about 30 minutes to spend with their children each evening. Over a quarter of parents wish they had more time for this.
Dr Halsey worked on some research with the makers of Ribena Plus. “There is no one as tough on their own parenting skills as a parent – but this study shows there is no need for parents to be so harsh,” she said.
She’s concluded that parents only need to spend about 12 minutes at evening with their kids, as long as they ask the right questions. The questions are meant to help parents find out what’s happened – and going to happen – in their son or daughter’s life.
The questions Dr Halsey has planned for 8 to 14-year-olds are:

How leopards get their spots and tigers their stripes

 

WHAT GIVES A TIGER ITS STRIPES? ALAN TURING HAD A FEW IDEAS

Mathematical models enable us to understand many features of a growing embryo. For example, the patterns of hair colour that give leopards their spots and tigers their stripes can be produced by solving a mathematical equation with different inputs.
The information to form a fully-grown animal is encoded in its DNA, so there is a lot of data in a single cell. But there are only about three billion base pairs in DNA and tens of trillions of cells in the body. So minute details, such as the twists and whorls of a fingerprint, cannot be predetermined. Rather, they emerge during embryonic growth as a result of conditions determined by the DNA, following the basic laws of physics and chemistry.
Alan Turing is famous for cracking the Enigma code during the second World War, but he was a polymath, and worked on many other problems. In 1952, Turing published a paper, The Chemical Basis of Morphogenesis , presenting a mechanism of pattern formation. He developed a theory of how the chemistry in the cell influences factors such as hair colour.
Turing’s model included two chemical processes: reaction, in which chemicals interact to produce different substances; and diffusion, in which local concentrations spread out over time.
Suppose we have two chemicals, A and B, called morphogens, with A triggering hair colouring and B not doing so. Now suppose that A is a catalyst, stimulating production of further morphogens, whereas B suppresses production of them. Thus, A is called an activator and B an inhibitor.
Where A is abundant, the hair is black; where B is dominant, it is white. Now comes Turing’s crucial assumption: the inhibitor B spreads out faster than the activator A. So B fills a circular region surrounding the initial concentration, forming a barrier where concentration of A is reduced. The end result is an isolated spot of black hair where A is plentiful.
What is going on here is a competition between the reaction and diffusion processes. Many reaction-diffusion models have been proposed. The resulting patterns depend on the reaction rates and diffusion coefficients, and a wide range of geometrical patterns of hair colouring can result from this mechanism.
The figure here shows the concentration of chemical A for varying strengths of reaction and diffusion. High values of A are shaded black, as hair colouring in these regions is expected to be black. For strong diffusion, the regions are large and striped like a tiger. For weak diffusion, the black hair is confined to spots, like the coat of a cheetah.
Many patterns can be generated by varying the parameters. Thin stripes, like those on an angel fish, or thick stripes, like those of a zebra, can be generated, and clusters of spots found on a leopard’s coat can be produced. Biological systems are hugely complex, and simple mathematical models are valuable for elucidating key factors and predicting aspects of behaviour.
Traditionally, the life sciences have attracted young people passionate about science, but who may feel uncomfortable with mathematics. In the future, mathematics will play a vital role in biology and maths skills will be essential for students.
