Colon cancer advances faster in men

Posted: 28 September 2011

WASHINGTON: Men with colon cancer tend to have more advanced tumors than women of the same age, said a study out Tuesday that suggested screening guidelines may need to be adjusted for sex and age.

Currently, men and women age 50 and older are urged to get a colonoscopy to screen for growths or polyps that could form into tumors. Colorectal cancer is the fourth leading cancer killer worldwide, taking 610,000 lives per year.

The study in the Journal of the American Medical Association examined 44,350 participants in a national screening colonoscopy program from 2007 to 2010 in Austria.

The screenings look for adenomas, which are polyps or benign tumors as well as for particularly advanced adenomas and colorectal cancer.

The analysis found "a significantly higher rate of these lesions among men compared with women in all age groups, suggesting that male sex constitutes an independent risk factor for colorectal carcinoma," according to the study.

For instance, five percent of men age 50-54 had advanced adenomas compared to just 2.9 percent of women.

The rate of colorectal cancer in 55-59-year-old men (1.3 percent) was about the same as in women a decade older (65-69-year-old women were diagnosed at a rate of 1.2 percent).

The prevalence of colorectal cancer overall was twice as high among men, at 1.5 percent, compared to 0.7 percent in women.

The researchers noted that "deciding whether to adjust the age at which screening begins also requires considering whether the recommended age for women should be older or the recommended age for men younger."

However, the study stopped short of saying what that new age should be, saying further studies "are needed to demonstrate the relative clinical effectiveness of screening at different ages."

Study: Many Obese Patients Unconvinced Weight Poses Health Risks

Image via Wikipedia(GAINESVILLE, Fla.) -- A majority of overweight and obese patients seen in hospital emergency departments do not consider their weight to be a threat to their health, and say that doctors have never informed them of the risks of excessive weight gain, a new study finds.

HealthDay reports that researchers surveyed 450 randomly selected patients seen in the emergency department at Shands at the University of Florida in Gainesville, Fla., and asked them to respond to two questions. The first question that was asked was, “Do you believe your present weight is damaging to your health?” followed by, “Have other health professionals ever told you that you are overweight?”

The study found that only 19 percent of respondents who reported that their weight was unhealthy said they'd ever discussed it with a health care professional. Thirty percent of respondents who were told that their weight was unhealthy by their health care provider agreed with that opinion.

The study also found that 47 percent of obese and overweight men believed their weight was a problem, while the majority—53 percent—felt it wasn’t an issue.

Study author Dr. Matthew Ryan, an assistant professor of emergency medicine at University of Florida, found that women were more aware of the health issues surrounding obesity, as 62 percent reported that their weight was negatively affecting their health.

"We see the manifestations of obesity in the emergency department. Obesity is directly linked to other diseases—hypertension, diabetes, cancers, osteoarthritis, gallbladder disease, heart disease, strokes, and metabolic syndrome," Ryan said. "We see the acute exacerbations of chronic diseases."

Even amid all the health problems surrounded by excessive weight, only 36 percent of overweight or obese men and 50 percent of overweight/obese women reported discussing the issue with their doctors.

Back after 3 weeks out

Image by Unitopia via FlickrI was out for about 3 weeks, and it was quite an urgent trip that I had to make, me and my family.

At 83 years old, my mother was on a sick and frail physique, and at her last days, 5 in the hospital, where she showed recovery, then 5 at home, where she finally transpired, she was already begging for drugs so she can go away peacefully.

And in most cases of an impending death, on her last day, she summoned all her strength to savor a meal before passing over to her next life.

We will miss her, and we have to take care of our equally aged father who is left behind, now aged 87.

Hope to get back in circulation soon.

Popular drugs for men impact their sexual health

Image via Wikipediapublished on March 7, 2011

A new study published in The Journal of Sexual Medicine reveals that, for the first time, 5a-reductase inhibitors commonly used to treat urinary problems in patients with benign prostatic hyperplasia (BPH) and found in popular medications to treat hair loss, can produce, persistent erectile dysfunction (ED), depression and loss of libido, even after the medication has been discontinued.

Researchers led by Abdulmaged M. Traish, MBA, PhD, of BostonUniversity School of Medicine, examined data reported in various clinical studies from the available literature concerning the side effects of the 5 alpha reductase inhibitors, finasteride and dutasteride.

Prolonged adverse side effects on sexual function, such as ED, depression and diminished libido, were reported by a subset of men. Drug-related reduction in libido occurred in 4.2% and 1.8% of patients in the dutasteride and placebo groups, respectively. Reduced ejaculation and semen volume were also reported and in some patients, these drugs were associated with depression.

“For these reasons, patients and doctors are urged to discuss these issues openly and candidly and assess the risk benefit ratio prior to commencing therapy with 5a-reductase inhibitors” Dr. Traish notes.

Dr. Irwin Goldstein, editor-in-chief of The Journal of Sexual Medicine, has seen and evaluated numerous such patients. He further explained the importance of this study. “Young men are being prescribed 5 alpha reductase inhibitors as hair loss treatmentsthat may negatively impact their sexual life, possibly for a prolonged time after stopping the medication. Older men with symptoms of lower urinary tract symptoms or fearful of prostate cancer, now have to deal with new onset sexual and mental health problems. The growing use of 5 alpha reductase inhibitors is causing concerns.” Clearly more research is needed to better understand the basis for these drug-associated side effects but it is evident that 5 alpha reductase inhibitors prevent the synthesis of very critical central nervous system neurosteroids and lower a very important sex steroid hormone, dihydrotestosterone.

We have moved!

We have moved!

The renovation is not 100% done yet, but they are finishing touches only.

I was on leave from work for 3 days to do the unboxing and arranging and rearranging. That is usually the rigorous part of it. I'd usually go with the movers when they move the boxes and furnitures here and there, but for the 2nd batch, I stole away from them. I had to be in the flat for the houseworks!

Before the boxes came, we had to do a quick tidying up of the place. The usually debris and fine dust from the sawing and cutting and all others is quite a health hazard, so we did that before anything can be laid down on the floor. We did that on a Saturday night, and then concluded the neatening work on Sunday. So Monday morning was a clean day to unload and uncrate. it is not exactly a shining clean flat, but one that is now ready for transferring the whole motherload of things we brought from the other flat.

And today I'm back to work. 2 days, and I'd be again out for a weekend escapade with the whole family. It's been planned so long ago, last year actually, when we attempted, but was unsuccessful due to full booking on the rooms and all. So we thought of having it this year, and the booking was early, earlier than most folks would do, just to make sure we have slot available.

So, till then. We're next to the top, so I'll be snapping up some scenes, and be the judge whether or not they are nice pictures.

Au revoir!

Australian study finds diabetes link to flabby dads

SYDNEY - Men with high-fat diets are more likely to have diabetic children, research showed Thursday, in the first study linking a baby's health to what their father ate.

The study tracked a group of rats that were fed fatty foods until they were obese and showing precursory signs of type 2 diabetes and were then bred with females of average weight, explained lead researcher Margaret Morris.

Morris said that despite being reared on a strictly healthy diet, their offspring developed impaired glucose tolerance and insulin production when they reached young adulthood.

"If what we seeing here in a rat translates to a human it may well explain the emerging earlier rates of diabetes in younger and younger people," said Morris, from the University of New South Wales.

Rather than passing their ill health onto their children genetically Morris said the metabolic issues appeared to have come from damage done to the rats' sperm by their diet. It was the first study to uncover such a link, she added.

"We've known for a while that overweight mums are more likely to have chubby babies, and that a woman's weight before and during pregnancy can play a role in future disease in her children," she said.

"But until now, the impact of the father's environment - in terms of diet - on his offspring had not been investigated."

Morris said the message of the research, published in the latest edition of Nature, was that "blokes as well as women need to eat healthier, reduce smoking and reduce alcohol excess" before having children.

Mass screening for prostate of little value?

Mass screening for prostate brings few benefits

PARIS: Mass screening of men for prostate cancer has little impact on the toll from the disease and carries a risk of over-treatment, according to a review published by the British Medical Journal (BMJ) on Wednesday.

University of Florida professor Philipp Dahm looked at the outcome of six trials in which populations of men were tested either using a digital rectal examination or a blood test for an antigen linked to prostate cancer, or were untested.

Screening had negligible effect on the death toll from this disease or indeed on overall mortality.

"Our findings suggest that the expected impact in absolute terms would be modest at best," according to the paper.

Prostate cancer is the commonest non-skin cancer among men worldwide and, after lung tumours, is the second biggest cause of death from cancer among men in the United States. Most cases occur among men aged in their sixties.

Many countries have routine screening programmes for men in their middle age, but this policy is controversial.

One of the problems is that the so-called PSA antigen test, now 20 years old, cannot distinguish between low-risk tumours and aggressive lesions that are often fatal.

Antigen levels can also fluctuate according to the individual and may be skewed by prostate inflammation.

As a result, experts looking at systematic screening have squabbled over whether the benefit of detecting men in danger outweighs the potential harm of over-diagnosing and over-treating men who are healthy.

In a separate study published by the BMJ, researchers found that the level of antigen, as found among men at the age of 60, strongly identified those most at risk.

This would curb the need for repetitive PSA testing among those who were least vulnerable, say its authors.

Others who should be closely monitored are young men with a family history of prostate cancer or who have a relatively high level of PSA in their initial test.

STD afflicts 1 in 4 US teenage girls

The Red ribbon is a symbol for solidarity with...

Image via Wikipedia

This is now a sad fact, where promiscuity is taking its toll, and not on the adults, but on the teens. When science says, "nothing can happen without a cause," it has a basis for that premise.

The recent study on US teenage girls yielded just that: where there is 'free sex', there is free transmission of diseases; while it is said that 'the exercise of freedom makes us freer', it is the precedent act that makes us bolder to try again, and again, and again.

When the conscience is seared, and continuously seared, there comes a time when it already keeps mum and dies within us - until we realize the wrong that we have done.

A study reveals the seared conscience of the youth in the US, and other countries have the same social problem: where promiscuity rules, AIDS and other similar sexual diseases follow suit.

Here's is the report from AFP, lifted from ChannelNewsAsia.com:

1 in 4 teenaged US girls has sexually-transmitted disease: study

CHICAGO - One in four teenaged girls in the United States has been infected with at least one sexually transmitted disease, according to a study released Tuesday by the Centers for Disease Control and Prevention.

The first study to examine the combined national prevalence of common STDs among adolescent women in the United States estimates that at least 3.2 million teens aged 14 to 19 are currently infected.

Since the study only tested for the four most common sexually transmitted diseases, it is possible that the total prevalence among US teens is greater than the study's rate of 26 percent, the authors warned.

"Today's data demonstrate the significant health risk STDs pose to millions of young women in this country every year," said Kevin Fenton, director of the CDC's National Center for HIV/AIDS, Viral Hepatitis, STD and TB Prevention.

"Given that the health effects of STDs for women -- from infertility to cervical cancer -- are particularly severe, STD screening, vaccination and other prevention strategies for sexually active women are among our highest public health priorities."

Half of the 838 girls who participated in the study reported ever having sex and of those, 40 percent were infected with an STD.

African American girls were particularly at risk: 48 percent of all African American girls were infected with an STD compared to 20 percent of white teens tested.

The most common STD overall was human papillomavirus, or HPV, with an infection rate of 18.3 percent.

Chlamydia was discovered in 3.9 percent of the teens, trichomoniasis in 2.5 percent and herpes in 1.9 percent.

Infections rate rose to 50 percent among girls with three or more partners while 20 percent of those who had only had sex with one person had been infected.

"High STD infection rates among young women, particularly young African-American women, are clear signs that we must continue developing ways to reach those most at risk," said John Douglas, director of the CDC's Division of STD Prevention.

"STD screening and early treatment can prevent some of the most devastating effects of untreated STDs."

The CDC recommends HPV vaccination for all girls and women between the age of 11 and 26 and annual Chlamydia screening for sexually active women under the age of 25.

While most HPV infections will clear on their own, some will persist and can cause cervical cancer.

Two other studies released Tuesday found inadequate screening of high-risk teens.

The first study found that just 27 percent of young women seeking emergency contraception were screened for chlamydia or gonorrhea.

The second study revealed that only 38 percent of young women receiving contraceptive services associated with unprotected sex such as pregnancy tests were offered STD testing, counseling or treatment. - AFP/fa

Bedtime worries

Are you getting enough sleep?
by Eveline Gan

Updated 05:15 PM Mar 16, 2010

Three in a Bed: The Benefits of Sleeping with Your Baby

Restful Insomnia: How to Get the Benefits of Sleep Even When You Can't

Why Sleep? Your Guide to the Benefits of Sleep

IT WAS almost midnight when I started my research for this story.

Along the way, I got distracted by a friend's MSN message. We chatted for a while before I returned to my work.

By the time I decided to go to bed, I was simply too wired up to sleep, so I fiddled with my mobile phone and played my favourite game. I finally willed myself into a fitful sleep after 3am.

Needless to say, I was a wreck when my daughter woke me up at 9am the next morning.

A good number of people may find the above scenario familiar.

Inadequate sleep may sometimes be due to sleep disorders. However, in many cases, people often do not have enough sleep because they voluntarily choose to forgo sleep for other activities, said sleep experts.

While there are no formal statistics, Dr Lim Li Ling, president of the Singapore Sleep Society, reckoned that many adult Singaporeans do not get the daily six to eight hours of sleep that is needed for optimal well-being.

"Lack of sleep is a common and largely under-recognised cause of daytime sleepiness and other health problems in countries such as Singapore, where the lifestyle is hectic and round-the-clock activities (such as online shopping and games) are available," said Dr Lim, who is also the medical director and consultant neurologist at the Singapore Neurology and Sleep Centre at Gleneagles Medical Centre.

According to her, most people who have problems falling asleep generally have bad habits that are not conducive to healthy sleep.

"For example, it is common to see people work till late at night, and thus do not have enough of a wind-down period. This can make falling asleep difficult because the mind is not relaxed enough."

Dr Lim added that she noticed that most people do not get enough physical exercise and use stimulants such as caffeine to stay alert, habits which can affect one's quality of sleep. Long daytime naps, stress and eating late can also interfere with sleep.

To encourage Singaporeans to sleep more, the Singapore Sleep Society is introducing the Sleep An Hour More Movement when its Singapore Sleep Awareness Week (SSAW) launches this Friday.

The society is urging Singaporeans to "switch off your mobile phone, computer or TV, tuck in early, sleep in later or take a nap in the day", in order to sleep an extra hour each day (bosses, are you reading this?) during the 10-day campaign to feel the physical differences.

For obvious reasons, chronic sleep deprivation can cause excessive daytime sleepiness, fatigue and weariness, lack of concentration, irritability, a lousy mood, as well as affect cognitive function such as problem solving, learning and memory, said Dr Jenny Tang, medical director of SBCC Asthma Lung Sleep and Allergy Centre at Gleneagles Medical Centre. It can also affect one's immunity.

Lesser known negative effects include risking a bigger waistline.

Explained Dr Tang: "When people are sleep deprived, there is a chance that there will be a change in the balance of their appetite hormones, which results in a bigger appetite and desire to eat more."

She added that heart palpitation could also occur when people overuse stimulant substances such as caffeinated beverages to counter sleepiness.

"Through raising awareness of the many serious health issues which can arise from long term lack of good quality sleep, we hope to encourage more people to make sleep a priority for the sake of their emotional and physical wellbeing," said Dr Lim.

Good night, and good luck

Sleep tight with these tips from sleep expert Dr Lim Li Ling.

- Work out a sweat. Exercise helps one feel relaxed and less stressed, but don't exercise for at least four hours before bedtime.

- Avoid alcohol near to bedtime. And don't drink caffeinated beverages such as coffee and colas eight to 10 hours before bedtime.

- Have a bedtime routine that can help you unwind. Don't think about work before you sleep! Also, steer clear of stimulating activities such as online games before bedtime.

- Ditch heavy suppers. Eating close to bedtime can cause symptoms such as heartburn, which can disturb sleep.

- Go to bed and get up at about the same time every night and day respectively, including weekends. This will help anchor your circadian (biological) clock and establish a consistent rhythm of sleep.

- Use the bed mainly for sleeping and sex, not other activities. Can't get to sleep after 20 mins? Get out of bed and engage in a relaxing activity like light reading and go back to bed when you feel sleepy.

Does what you sleep on matter?

According to Dr Lim, most " average" mattresses and pillows are good enough for normal sleepers.

"Of course, a lousy sleeping surface can affect normal sleepers, such as a cold hard concrete floor or a mattress that is lumpy and causing back pain - but most people do not have to contend with such challenging situations," she said.

She added that people who suffer from sleep problems may need to make more effort to make the bedroom environment more conducive to sleep. "This could include air-conditioning, soft or firm pillows ... whatever the patient prefers."

A new "legal" drug to be wary of?

Image via Wikipedia

K2 JUST LIKE THE REAL THING

---------------------------

JEFFERSON CITY (Missouri) - There may be nothing like the real thing, but some industrious marijuana users have seized on an obscure but easily accessible substance that mimics the drug's effects on the brain - creating a popular trade in legal dope that has stymied police in the United States.

The users are buying a product known as K2 that is commonly sold as incense.

Produced in China and Korea, the mixture of herbs and spices is sprayed with a synthetic compound chemically similar to THC, the psychoactive ingredient in marijuana.

Users roll it up in joints or inhale it from pipes, just like the real thing.

Though banned in most of Europe, K2's key ingredients are not regulated in the US - a gap that has prompted lawmakers in Missouri and Kansas to consider new legislation.

Authorities in Kansas discovered ex-convicts on probation smoking K2, and said it is spreading to high school students.

K2 costs between US$20 ($28) and US$50 for three grams - similar to the street price of marijuana - but with the key advantages of being legal and undetectable in drug tests. The key ingredients are believed to be the unintended result of scientific research on marijuana's effects.

Dr John Huffman, an organic chemistry professor, was researching the effects of cannabinoids on the brain when his work resulted in a 1995 paper that contained the method and ingredients used to make the compound. That recipe found its way to marijuana users. "People who use it are idiots," said Dr Huffman, referring to K2 smokers.

A proposed Bill in Missouri would make possession a felony punishable by up to seven years in prison, identical to punishments given to users of real marijuana. There is no data on the drug's toxicity. AP

Brainy kids - born or made?

KIDS

Experts say that parents and caregivers play an important role in developing a child's intelligence

Eveline Gan

eveline@mediacorp.com.sg

AT AN age when most of her peers were figuring out how to use the potty, 18-month-old Janelle Kuah underwent private enrichment classes that involved memory-training and speed-learning.

Now aged 4, Janelle has memory skills which probably exceed that of many adults. She is able to memorise 50 different images and recite them in sequence at lightning speed. Her ability to pick up new words, as well as phrases in different languages and dialects, is just as "amazing", said Janelle's mother, Chua Ann Nee.

"The lessons aren't cheap, but I feel the training definitely helps with her brain development. She's faster than most of her peers in nursery," added Ann Nee, who forks out about $65 for an hour-long session.

But is it really possible to develop a child's intelligence?

The answer, according to experts Today spoke to, is yes.

"It is not a new idea to train and improve intelligence. Intelligence theories have always divided intelligence into two components - the part you're born with, and the part that can be learnt," said Dr Joanne Staunton, a cognitive psychologist at Mount Elizabeth Medical Centre's Singapore Baby and Child Clinic.

Psychologists Today spoke to said intelligence can be measured using standardised intelligence tests, administered only by trained psychologists (online IQ quizzes are not reliable). Regardless of age, the average IQ for any person is between 90 and 110, said Dr Staunton.

However, said the psychologists, you should only have your child's intelligence tested if you suspect your child has learning difficulties, or has experienced difficulties at school.

At KK Women's and Children's Hospital (KKH), IQ tests are only conducted for children who have been found to have developmental delay and learning problems.

According to Ms Frances Yeo, principal psychologist at KKH Psychology Service, the human brain is not developed completely at birth and continues to develop from childhood to adulthood.

"Appropriate interventions, training and schooling will help the child to develop cognitive skills," said Ms Yeo.

"On the other hand, illness, head injuries or any medical conditions that affect how the brain develops can 'derail' learning development."

But before you rush headlong into enrolling your child in brain training enrichment courses, consider this.

New research has shown that strong loving emotional attachments with adults - such as with parents or caregivers - can shape infants' brain development positively, said Ms Therese Tan, a committee member of the professional development team at Association for Early Childhood Educators (Singapore).

"It was found that the enriching responses and positive cues that babies experienced with such relationships facilitated neural (brain nerves) activity," added Ms Tan.

Besides enrichment courses, Dr Staunton added that there are also plenty of day-to-day activities parents or caregivers can do to develop a child's IQ.

Ms Jocelyn Khoo, executive director of The Shichida Method (S) Pte Ltd, which focuses on brain training in young children, believes that a well-rounded childhood - comprising a wholesome diet, parent-child bonding, social skills and physical fitness - is just as important as the training.

"A parent must not get too caught up with developing a child's intellect and pay less attention to other parenting aspects, such as providing love and being patient. Doing so might create hidden stress in children, thus leading to reduced learning capability," added Ms Khoo.

SMART MOVES

Cognitive psychologist Dr Joanne Staunton suggests a list of five things parents and caregivers can do to develop their child's IQ.

1. Teach your child to approach things in a step-by-step manner.

2. Help your child to categorise items by discussing their similarities and differences.

3. Teach your child to follow instructions. For instance, tell your child to "draw a circle". Gradually, get your child to follow instructions in an incremental manner by increasing the instructions, such as "draw a square and a circle".

4. Show your child how to complete patterns. After teaching your child a sequence, such as numbers one to 10, encourage your child to find a missing number.

5. Develop your child's language skills. This can be done by reading to your child, using new words or simply asking your child questions.

The daily grind: Sex for a week boosts sperm quality

Would this finding help in producing better kids? Healthier? Cannot tell?

----------

AFP - Wednesday, July 1

A painting in the lobby of the world's biggest sperm bank, Cryos, which has its headquarters in the Danish city of Aarhus. Men seeking to become a dad should have sex each day, or ejaculate daily, for a week before their partner ovulates in order to maximise sperm quality, according to a study by Australian fertility specialists.

PARIS (AFP) - - Men seeking to become a dad should have sex each day, or ejaculate daily, for a week before their partner ovulates in order to maximise sperm quality, according to a study presented on Tuesday.

Australian fertility specialist David Greening recruited 118 men whose sperm had a higher-than-normal level of DNA damage.

Before the test, on average 34 percent of the group's sperm was rated as damaged, meaning that it was classified as "poor" in quality. Among individuals, this ranged from 15 percent to 98 percent.

The men were asked to ejaculate daily for seven days, but were not given any drugs or told to make any changes to lifestyle.

After seven days, their sperm was examined again.

The average of damaged sperm fell to 26 percent, placing it in the category of "fair" in quality.

Fourth-fifths of the men saw an increase in sperm quality, and many of them moved into the "good" range and out of the "poor" or "fair" categories.

However, one-fifth saw a decline in sperm quality.

Greening, an obstetrician and endrocrinologist at Sydney IVF, an Australian company that carries out assisted reproduction, said the improvements were "substantial and statistically highly significant."

Daily ejaculation not only boosted sperm quality for most of the men, it also helped sperm motility -- another big factor in successful fertilisation -- even though volumes of semen declined, he said.

Greening presented his findings at a conference in Amsterdam of the European Society of Human Reproduction and Embryology (ESHRE), which provided details in a press release.

The research did not investigate whether the improvement in sperm quality led to better pregnancy rates. But previous work has shown that sperm that is less damaged and more mobile has a better chance of leading to a healthy baby.

"These results may mean that men player a greater role in fertility than previously suspected, and that ejaculatory frequency is important for improving sperm quality," said Greening.

Why this is so is unclear.

Greening said he suspected that the longer sperm stays in the testicular ducts, the greater its exposure to rogue oxygen molecules that damage cells.

His advice to couples would be to have sex, or to ejaculate, daily in the runup to ovulation or to sperm donation for in-vitro fertilisation (IVF).

"The optimal number of days of ejaculation might be more or less seven days, but a week seems manageable and favourable," he said.

"It seems safe to conclude that couples with relatively normal semen parameters should have sex daily for up to a week before ovulation date."
