Smoking Before Fatherhood May Raise Asthma Risk in Kids: Study

Men who smoke before becoming a parent may put their children at increased risk for asthma, a new study suggests.

Smoking Before Fatherhood May Raise Asthma Risk in Kids

Researchers analyzed the smoking habits of more than 13,000 men and women, and then looked at the incidence of asthma in their children. The results showed that asthma was much more common in children whose fathers were smokers before conception. A child’s risk of asthma increased if the father smoked before age 15, and the risk grew the longer the father smoked.

While the finding showed an association between a man’s smoking history and asthma risk in his children, it did not prove cause-and-effect.

There was no association between a mother being a smoker prior to conception and a child’s risk of asthma, according to the study that was to be presented Monday at the European Respiratory Society meeting in Munich, Germany.

“This study is important as it is the first study looking at how a father’s smoking habit pre-conception can affect the respiratory health of his children,” Dr. Cecile Svanes, of the University of Bergen in Norway, said in a European Lung Foundation news release.

“Given these results, we can presume that exposure to any type of air pollution, from occupational exposures to chemical exposures, could also have an effect. It is important for policymakers to focus on interventions targeting young men and warning them of the dangers of smoking and other exposures to their unborn children in the future,” Svanes added.

Animal studies have suggested that a father’s exposures before becoming a parent can harm his offspring, the researchers noted.

Research presented at meetings should be viewed as preliminary until published in a peer-reviewed journal.

12 Unexpected Things that Mess With Your Memory

12 Unexpected Things that Mess With Your Memory

Surprising memory stealers

You regularly ransack the house to find your keys. You suddenly can’t recall the name of your kid’s teacher. You made your six-month dentist appointment three months late. Sound familiar? Fear not: most forgetfulness isn’t anything serious, says Majid Fotuhi, MD, PhD, founder and chief medical officer of NeurExpand Brain Center in Luterville, MD and co-author of The Memory Cure. Lack of sleep, certain medications, and even stress can impact your memory. “Fortunately, your brain is malleable, meaning it changes and improves,” says Dr. Fotuhi. “Memory can be boosted with simple powerful interventions.” Here are surprising things that impact your memory in both good and not-so-good ways.

A dysfunctional thyroid
When your thyroid’s out of whack, you may feel too hot, too cold, anxious, depressed—and your memory may also be lagging. “Although the thyroid doesn’t have a specific role in the brain, memory loss is the one thing a person notices when it stops functioning normally,” says Dr. Fotuhi. A butterfly-shaped gland that sits along the front of your windpipe, the thyroid reigns over almost all your body’s metabolic processes. “People with high or low thyroid levels—which are very common in women—may have difficulty with memory and concentration,” he says. Ask your doctor for a simple thyroid test to determine if it’s the culprit behind your memory problems.

Hot flashes
Every time hot flashes make you you feel like sticking your head in the freezer, you may also feel a fog rolling into your brain. “The more hot flashes a woman experiences during menopause, the worse her ability to remember names and stories,” says Dr. Fotuhi. “Fortunately, hot flashes don’t damage the brain in any way. Memory improves once the hot flashes subside.” Other menopause-related symptoms contribute to memory loss, including insomnia and sleep apnea, Dr. Fotuhi says.

Lack of sleep
Last night’s late party makes it less likely you’ll remember your new coworker’s name the next day. “While some part of the brain takes a siesta when we sleep, deeper areas involved with memory and emotional response become relatively more active,” says Allen Towfigh, MD, medical director of New York Neurology & Sleep Medicine. “Individuals with sleep deprivation and sleep disorders not only suffer from impaired memory but also daytime fatigue, impaired attention, and reduced reaction time.” The standard recommendation of eight hours of sleep a night doesn’t necessarily work for everyone. If you wake up fatigued and fall asleep unintentionally during the day, then you may need more sleep, says Dr. Towfigh.

Anxiety and depression
Worrying about an upcoming presentation in front of the CEO may also hinder your memory, several studies show. “We don’t understand the exact link, but strong evidence indicates depression, anxiety, and bipolar disease disrupts the neural circuitry involved in developing and retrieving memories,” says Dr. Towfigh. “The severity of the memory loss often mirrors the severity of the mood disorder—severe depression brings about equally severe memory loss.” Prolonged periods of everyday stress increase cortisol levels in the brain, which causes our brain cells to lose synapses (the bridges that connect our brain cells to one another), and make it more difficult to create and retrieve memories. The good news is when memory loss exists with a mood disorder (including anxiety and depression), the memory loss is usually at least partially reversible. “As the individual’s mood improves, often so does the memory loss,” says Dr. Towfigh

Prescription drugs
Check your medicine cabinet: many common prescription drugs can make you feel forgetful. Anxiety disorder meds like Xanax, Valium, and Ativan (which are benzodiazepines) put a damper on the part of the brain that moves events from the short-term to the long-term memory. Tricyclic antidepressants have a similar effect. Heart medicines including statins and beta blockers have also been linked to memory issues, as have narcotic painkillers, incontinence drugs, sleep aids, and even antihistamines like Benadryl. Bottom line: Don’t stop taking your (potentially life-saving) medications, but talk to your doc if you believe any drug you’re on may be messing with your memory.

Smoking
If you’re still smoking, that may help explain memory lapses. “Smoking damages the brain by impairing its blood supply,” says Dr. Towfigh. Research published in the Archives of General Psychiatry gathered from data obtained from more than 7,000 men and women found a more rapid decline in brain function (which included memory along with vocabulary and other brain functions) with age than from those who never smoked. “Furthermore, cigarette smoking promotes the accumulation of abnormal proteins which impair the brain’s ability to process and relay information

A high-fat diet
Greasy burgers and French fries pack on pounds and are hard on your heart—and they may also cause memory issues. One study revealed that adolescent mice had poorer learning and memory skills after being fed a high-fat diet for eight weeks, while another study on middle-aged rats found that the hippocampus (the part of the brain responsible for short-term memory) may be particularly vulnerable to the impact of high-fat diets.

More research is needed to determine for sure whether or not high-fat diets impact human memory, but here’s what we do know: Calorically dense diets promote type 2 diabetes, hypertension, and cardiovascular disease, which can all do damage to our brains, says Dr. Towfigh. “This holds true earlier in life, too. Studies link childhood obesity with a reduced attention span and impaired concentration and focus.”

Stress
A sudden emergency can make it tough to recall something as simple as your home address. A rat study published in Neuron shows that stress hormones influence an area of the brain area that controls working memory. Researchers found that repeated stress reduced receptors in the part of the brain that’s connected to thought processes Although this study involved animals, the human brain works similarly, explains Dr. Towfigh. “Repeated or chronic stress can be harmful. Regular exposure to elevated glucocorticoids (a hormone released by the adrenal gland) also causes our brain cells to reduce receptors, making brain cells less capable of responding to neurochemical (brain chemicals) cues.” Finding ways to relieve stress may help: Practicing meditation does double duty by easing stress and helping improve memory, according to a study from the University of California, Santa Barbara. College students who completed eight 45-minute meditation sessions over two weeks increased their average GRE exam scores from 460 to 520 and showed improvement on tests of working memory.

Germs
A nasty cold sore does more than make you feel self-conscious—it may be messing with your memory, according to a 2013 study in Neurology. Researchers found that people who exposed to many germs, such as herpes simplex type 1 (the cold sore virus), over their lifetimes were more likely to have memory problems than those exposed to fewer germs. Among more than 1,600 study participants, those with a higher “infectious burden” had a 25% increase in the risk of a low score on a cognitive test. Although there is no vaccine for the cold sore virus, childhood vaccinations against other viruses could help prevent problems later in life, the researchers suggest. In addition, regular exercise may help too—doctors think repeated infections may damage blood vessels, since a high infectious burden is also linked to a greater risk of stroke and heart attack.

Green tea
Now for some good news: chemicals found in green tea may help improve your memory, according to a University of Basel study. “Several compounds, EGCG and L-theanine, in green tea increase neurogenesis (growth of new brain cells) in the hippocampus, the part of the brain used for short-term memory and learning new things,” says Dr. Fotuhi. How much green tea has not yet been determined, says Dr. Fotuhi, who recommends combining green tea with other healthy habits such as exercise for greatest memory improvement benefits.

Exercise
Regular sweat sessions also help keep memories sharp. “Physical exercise improves mood and sleep and by doing so, it invariably improves cognition and memory,” says Dr. Towfigh. An animal study published in Brain, Behavior and Immunity, for example, showed daily exercise increased brain cell growth after 12 weeks of conditioned running. Dr. Fotuhi recommends 45 minutes of aerobic exercise four days a week for the best memory boost.

Oral cancer claims one life every six hours in India

Oral cancer claims one life every six hours in India

One person dies every six hours due to oral cancer in the country, signalling an alarming rise in the incidence of the disease, according to a top orthodontist.

The situation could be still graver as many cases of the disease went unreported, Secretary-General of the Indian Dental Association Dr Ashok Dhoble told PTI from Mumbai.

“Cases of the disease and deaths resulting from it in rural areas and among the poorer sections of society are hardly registered,” he noted.

He pointed out that with the high prevalence of smokers and widespread use of other chewable tobacco products, India has seen a steep growth in the number of oral cancer patients in the past decade.

In fact, Dr Dhoble said, oral cancer approximated to 40 per cent of all cancer-related disease in the country with the Northeastern states mostly affected.

“All Northeastern states are badly affected by the disease. The states like West Bengal, Andhra Pradesh, Gujarat and Tamil Nadu are also affected,” he said, adding every third person in these states used tobacco-related products.

Talking about measures to curb the prevalence of the deadly disease, he said that nothing short of a total ban on the use of tobacco was the only way.

“There is no other way to curb oral cancer… You have to ban tobacco in its every form,” Dr Dhoble said, pointing out that it was the nicotine present in the tobacco which made it addictive and difficult to kick the habit.

“Our government also understands the problem… But the huge number of people employed with the tobacco industry is the problem… The government has to provide them with an alternative livelihood and then ban tobacco totally,” he said.

He said a dentist was the first person to diagnose it since oral cancer was not just limited to teeth, but mouth, tongue and integral part of pharynx and gums as well.

The orthodontist explained that oral cancer was 100 per cent curable only if it was reported in the first stage. But once it slips into the second stage, the patient is left with a life span of just five years.

“I will advise people to visit a dentist and not to ignore even if there is a slight problem in the mouth… But above all they have to give up using tobacco in every form. That’s the best medicine,” Dr Dhoble said Stressing the need to educate people on the disease, he said that the Indian Dental Association, which will hold the FDI Annual World Dental Congress in Delhi in September, had been conducting awareness camps and counselling people for the last five years.

E-cigarettes may have unknown health risks: Study

33%37144_eco_25-04-2014_p06-p07-2.qxp

Despite our growing knowledge that smoking tobacco is bad for us more than 40 million Americans are cigarette smokers. Smoking cigarettes is known to cause damage to every organ in your body, and smoking-related illnesses are responsible for one out of every five deaths in the U.S. But nearly 70 percent of smokers report they want to quit, and a little more than 42 percent say they’ve tried to quit during the past year

In 2009 there was a 10 percent decrease in cigarette sales in the U.S., and while that directly followed an increase in the federal cigarette tax, it’s not only price that’s changing the habits of American smokers. Electronic cigarettes (known also as e-cigarettes) have also contributed.

Global sales of smokeless tobacco products, including smokeless inhalers, has grown to nearly $3 billion — and continues to grow. In an attempt to quit the tobacco habit as many as one-fifth of smokers have tried e-cigarettes [source: Ross].

E-cigarettes were first developed in China and were introduced to the U.S. market in 2007. Many are similar enough in appearance to be mistaken for regular tobacco cigarettes. But one look inside and you’ll see the main difference: This is a tobacco-free product. E-cigs are actually vaporizers; instead of burning tobacco, the mechanism heats up a liquid.

The liquid turns into vapor, which is then inhaled, or “vaped.” While some argue that vapor offers health advantages over traditional cigarette smoke, regulatory agencies and some health experts aren’t so sure that’s true. Before you consider taking up the e-cigarette habit, read on to get the facts.

Smoking during pregnancy may raise heart defects risk in babies

Pregnant Woman Smoking

Researchers have shown that risk for congenital anomalies is highest among babies born to older women who smoke.

The authors of this study used birth certificate data and hospital discharge records from Washington state to determine if maternal smoking during the first trimester of pregnancy is linked to heart defects and if so, what types of defects.

Lead author Patrick M. Sullivan, MD, FAAP, clinical fellow in pediatric cardiology at Seattle Children’s Hospital and a master’s student in epidemiology at the University of Washington School of Public Health, said I care for kids with complex congenital heart disease on a daily basis, and I see these kids and their families enduring long hospitalizations and often sustaining serious long-term complications as a result of their disease.

Sullivan said usually, the cause of a heart defect is unknown. I saw this research as an opportunity to study what might be a preventable cause of congenital heart defects.

Using hospital discharge records, researchers identified 14,128 children born with a variety of heart defects from 1989-2011. They matched these cases to 62,274 children without heart defects born in the same year.

Then, they compared the proportion of children with heart defects whose mothers reported smoking during pregnancy to the proportion of children without heart defects whose mothers smoked. Mothers’ smoking status, as well as how much they smoked daily, was available from birth certificates.

Newborns whose mothers smoked were at about a 50 to 70 percent greater risk for anomalies of the valve and vessels that carry blood to the lungs (pulmonary valve and pulmonary arteries) and about a 20 percent greater risk for holes in the wall separating the two collecting chambers of the heart (atrial septal defects). All of these defects often require invasive procedures to correct.

E-cigarettes next big smoking poison, warns study

The fast spreading e-cigarettes are undoing the anti-smoking efforts of the last three decades, health experts warn.

Also, the number of people being poisoned by e-cigarettes in the US has gone up manifold in the last few years, according to official reports.

The number of calls to poison centres in the US relating to e-cigarettes has risen from one per month in September 2010 to 215 per month in February 2014.

The figures, from the Centres for Disease Control and Prevention (CDC), also show the number of calls per month relating to conventional cigarettes did not increase in the same way.

The CDC statistics show that more than half of the calls relate to children under the age of five.

Poisoning related to e-cigarettes involves the liquid containing nicotine used in the devices.

“This report raises another red flag about e-cigarettes — the liquid nicotine used in e-cigarettes can be hazardous,” CDC director Tom Frieden said in a statement.

E-cigarette liquids come in candy and fruit flavours that are appealing to children.

“The most recent National Youth Tobacco Survey showed e-cigarette use is growing fast, and now this report shows e-cigarette related poisonings are also increasing rapidly,” Tim McAfee, director of CDC’s office on smoking and health, was quoted as saying.

The study comes close on the heels of news that the Welsh government might include e-cigarettes under the smoking ban.

Passive smoking causes irreversible damage to kids’ arteries

smoking]

Exposure to second-hand smoke in childhood causes irreversible damage to children’s arteries – increasing their risk of heart attacks or strokes when they grow up, according to a large international study published on Wednesday.

The research, which lends weight to campaigns for smoking to be banned in private cars and homes, found passive smoking leads to a thickening of children’s artery walls, adding some 3.3 years to the age of blood vessels by adulthood.

“Exposure to passive smoke in childhood causes direct and irreversible damage to the structure of the arteries,” said Seana Gall, a researcher in cardiovascular epidemiology who led the study at the University of Tasmania.

She said parents, or even those thinking about becoming parents, should quit smoking – both to aid their own health and protect the future health of their children.

Smoking causes lung cancer, which is often fatal, and is the world’s biggest cause of premature death from chronic conditions like heart disease, stroke and high blood pressure.

On top of the 6 million people a year killed by their own smoking, the World Health Organization (WHO) says another 600,000 die a year as a result of exposure to other peoples’ smoke – so-called second-hand or passive smoking.

Of the more than 4,000 chemicals in tobacco smoke, at least 250 are known to be harmful and more than 50 are known to cause cancer, the WHO says – and creating 100 percent smoke-free environments is the only way to protect people fully.

About 40 percent of all children are regularly exposed to second-hand smoke at home, and almost a third of the deaths attributable to second-hand smoke are in children.

ARTERY WALLS

This latest study, published in the European Heart Journal, was the first to follow children through to adulthood to look at links between exposure to parents’ smoking and thickness of the innermost two layers of the arterial wall, known as carotid intima-media thickness (IMT).

Researchers from Finland and Australia looked at data from 2,401 people in Finland 1,375 people in Australia who were asked about their parents’ smoking habits. The scientists used ultrasound to measure the thickness of the children’s artery walls once they had reached adulthood.

The results showed that carotid IMT in adulthood was 0.015 millimeters thicker in those exposed to both parents smoking than in those whose parents did not smoke.

Gall said that while this was a “modest” increase, it was nonetheless an important extra and irreversible risk for suffering heart attacks or strokes later in life.

Since children of parents who smoke are also more likely to grow up to be smokers themselves, and more likely to be overweight, their heart health risks are often already raised, she said, and the second-hand smoke adds yet more risk.

The researchers said the findings showed reducing children’s exposure to smoke is a public health priority.

“Legislation can reduce passive smoke exposure, with restriction of smoking in public places reducing hospitalizations for cardiovascular and respiratory disease,” they wrote, adding that banning smoking in cars with children in them would also have a significant positive effect.

The United States, Australia and Canada have already banned smoking in cars carrying children, and Britain said last month that it too would be introducing a ban soon.

Diabetes: Tips for stable, steady blood sugar levels

Diabetes is a lifelong medical condition that makes people resistant to insulin, a hormone that allows blood glucose to enter the body’s cells where it is used as energy.

Diabetics have too much glucose in the blood because the body cannot use it properly and they need extra insulin to allow their cells to take in sugar from their blood.

Diabetes has three distinct classifications. These include Type 1 Diabetes wherein a glitch in immune system attacks its own beta cells in the pancreas. A person with type 1 diabetics is dependent on insulin shots for life.
Type 2 Diabetes is triggered by reduced insulin sensitivity combined with reduced insulin secretions. As the disease progresses therapeutic replacement of insulin becomes necessary. The third, gestational diabetes occurs during pregnancies and is fully treatable but requires careful medical supervision throughout pregnancy.

What causes diabetes?
According to experts, nature as well as nurture play a vital role in triggering diabetes. Though, the ailment is said to be passed down from parents to offspring, the gene susceptibility is just 25 percent. A sedentary lifestyle, adhering to unhealthy diet high in saturated fats and junk food, makes us more vulnerable to the ailment.

If diabetes goes uncontrolled it can lead to loss of eye sight, renal failure, cardiovascular problems, gangrene, and amputations, hence maintaining blood sugars within the target range is crucial.

Tips to control diabetes
Though not many can control diabetes without medication, awareness of what makes your blood sugar spike, plus a few simple lifestyle changes can make a real difference.

Diet
In terms of food intake, what you eat, how much you eat and when you eat is paramount for diabetes management. Switch to vegetables and fruits, whole grains, lean meats, or proteins and avoid heavy, processed or refined foods and sweets. Eat five to six small portions throughout the day at a regular time rather than when you feel like it. Balance out all the nutrients in every meal as this will help you keep your insulin level on an even keel.

Regular exercise regimen
Diabetes need to adhere to a regular exercise regimen. Physical activity not only increases insulin sensitivity, but it reduces stress, improves blood pressure and cholesterol and also controls weight. Aim to exercise at least 30 minutes a day, five times a week. Any activity ranging from brisk walking, using stairs instead of elevators, vacuuming that raises metabolic rate and levels out blood sugar counts toward your daily total.

Keeping weight in check
Being overweight is an indicator of diabetes. Excess body fat, especially stored around the abdomen, can increase the body’s resistance to the hormone insulin. Though shedding pounds and keeping it off is a challenging task, losing even a relatively small amount of weight can go a long way in keeping blood sugars levels steady.

Eyes
Visit an ophthalmologist experienced in treating diabetic to look for diseases such as retinopathy, one of the most common complications of the disease.

Quit smoking
Smokers are twice as likely to develop diabetes as opposed to non-smokers. Lighting up reportedly increases insulin resistance and also narrows blood vessels which in turn limit circulation to your legs and feet.

Drink moderately
Excessive alcohol consumption can pile on the pounds and also spike blood pressure and triglyceride levels. Two standard drinks a day for men and no more than one for women is recommended

Get enough sleep
Adjust the hours so that you get a consistent eight hours of shut eye. Researches have established that inadequate sleep has a significant effect on your blood sugar and insulin levels.

Stay hydrated.
Drink water to stay energized and hydrated. Swapping coffee, soda or juices with water will slash the total sugar and calories in your diet. You can add a dash of lemon or lime or an orange wedge for flavor.

Diabetes is serious, but is a manageable disease. Just incorporate these simple tips to prevent or delay some of the serious problems related with diabetes.

WHO’s Anti-Smoking Guidelines Save 13 Million In China

Anti-smoking campaigns have proven effective in some parts of the United States, but what effect could they have on a country ranked third among the number of active smokers? Guidelines implemented by the World Health Organization (WHO) could prevent up to 13 million smoking-related deaths in China by 2050 and could reduce the number of smokers by more than 40 percent.

According to the WHO, half of all smokers will die as a result of tobacco use including upward of six million people each year. Out of the global impact of smoking-related fatalities, 600,000 have been attributed to non-smokers who were exposed to second-hand smoke. Approximately, 80 percent of the estimated one billion smokers around the world live in low- and middle- income countries. Countries who have implemented bans on tobacco advertising, promotion, and sponsorship have decreased tobacco consumption by seven percent in some countries and 17 percent in others.

Researchers from Spain, France, and the U.S. estimated the potential health impact of the WHO’s proposal using the SimSmoke Tobacco Control Policy model, an international record of smoking prevalence and smoking-related deaths. Researchers said, in a press release, implementing the guidelines set forth by the WHO “would lead to as much as a 34% relative reduction in male smoking prevalence by 2020, and a 41% reduction by 2050.” If the WHO guidelines are ignored, China can expect an additional 50 million smoking-related deaths between 2015 and 2050.

Following the application of smoke-free air laws and tobacco marketing bans have showed “potent and immediate” effects in other countries. Implementing smoke-free air laws in China could reduce smoking rates by nine percent in 2015. Furthermore, increasing increase taxes by 75 percent could also reduce the number of smokers by 10 percent of both males and females by 2015. By 2015, the number of smoking-related deaths was expected at 932,000 men and 79,000 women.

When 2050 finally rolls around, the research team expects the number of female smokers in China to reduce by 12 percent and male smokers by 13 percent. Between 2015 and 2050, researchers expect that WHO guidelines will save 3.5 million lives. A complete ban on tobacco marketing could help reduce smoking by four percent in China. The research team was also confident that “without the implementation of the complete set of stronger policies, the death and disability legacy of current smoking will endure for decades in China.”

When 2050 finally rolls around, the research team expects the number of female smokers in China to reduce by 12 percent and male smokers by 13 percent. Between 2015 and 2050, researchers expect that increasing tobacco sales will save 3.5 million lives. Combine that with smoke-free air campaigns and China could see a reduction in 13 million deaths by the year 2050. A complete ban on tobacco marketing could help reduce smoking by four percent in China. The research team was also confident that “without the implementation of the complete set of stronger policies, the death and disability legacy of current smoking will endure for decades in China.”

Tips for tackling asthma during pregnancy

Expecting a child is the most exciting and happy phase in a woman’s life, but suffering from an asthma attack is the worst nightmare a pregnant lady can face.

As per National Asthma Education Group for the Centers for Disease Control and Prevention (CDC), asthma is one of the most common diseases that can complicate a pregnancy.

It is advisable for pregnant women to identify the early asthma symptoms as the disease’s effects on pregnant women are appalling, Parents India magazine reported.

If asthma becomes uncontrolled, it can bring about a risk for the mother’s as well as for the baby’s health. This situation can even lead to further complications like oxygen deprivation for the baby, morning sickness, vaginal bleeding, high blood pressure and protein in the urine after 20 weeks of pregnancy (preeclampsia), restricted fetal growth, complicated labor, need for a C-section, premature birth, low birth weight and in extreme cases, the baby’s life might be in jeopardy.

Since the fetus gets its oxygen from the mother’s blood, this condition leads to decreased oxygen in the fetal blood.

Swimming is known to be a particularly good exercise for women suffering from asthma. Using an inhaled bronchodilator ten minutes before you exercise may help you better tolerate your recommended exercise during pregnancy.

It is also advisable for the pregnant women who have asthma to get their condition monitored on a regular basis. A check-up once in three weeks is recommended by expert doctors worldwide.
