Going solo when trying to quit smoking isn’t enough, one lung health expert says. “Smokers develop a physiological dependence on nicotine, and they need more than willpower to quit,” said Dr. Danish Ahmad, a pulmonologist with Penn State Health’s Milton S. Hershey Medical Center. The American Cancer Society says that smokers typically try quitting eight to 10 times before succeeding. That may sound daunting, but there’s good news. According to Diane Schmeck, a certified tobacco treatment specialist at Penn State Health, “The more times people try to quit, the more successful they might be the next time.” Though about 70% of smokers know they want to quit, particularly to avoid lung cancer and cardiovascular disease, there are many lesser known health risks. Smoking can cause cancer of the esophagus, pancreas and stomach, as well as breathing issues that can lead to emphysema. “Smoking affects your small blood vessels, which can mean poor circulation in the arms or legs, or a greater risk of erectile dysfunction in males,” Schmeck said in a Penn State Health news release. But if you quit, benefits can be seen immediately, Ahmad said. “Within 20 minutes, a smoker’s heart rate and blood pressure improves, and within 12 hours, the carbon monoxide level drops,” he said. Smokers have the highest likelihood of quitting through programs integrating one-on-one counseling, group support and medication,… read on >

MONDAY, Feb. 17, 2020 (American Heart Association News) — Bleeding strokes are the deadliest type of stroke and the hardest to treat. What might make matters worse is having both diabetes and Alzheimer’s disease versus either condition alone, new research shows. The study looked at 2,071 adults in the Kentucky Appalachian Stroke Registry who had a hemorrhagic stroke. The researchers reviewed each patient’s health records to look for a previous diagnosis of diabetes or Alzheimer’s disease. They found 75% of those with both conditions had died or needed hospice or long-term care after their stroke compared to 39% with neither condition, 42% with diabetes alone, and 62% with Alzheimer’s disease alone. This stroke registry gave us “the opportunity to think about how having more than one (health condition), like diabetes and Alzheimer’s disease, could influence outcomes compared to having just one,” said the study’s lead researcher Amanda L. Trout, a scientist at the Center for Advanced Translational Stroke Science at the University of Kentucky in Lexington. Trout will present the preliminary study Wednesday at the American Stroke Association’s International Stroke Conference in Los Angeles. Diabetes occurs when a person’s blood sugar is too high. The condition increases risk for stroke, heart disease and other health problems. Likewise, previous studies suggest stroke risk is higher for people with Alzheimer’s disease, a brain disorder that slowly erases… read on >

Little ones who stay up late may have a higher risk of becoming overweight by the time they are school-age, a new study suggests. Researchers found that young children who routinely got to sleep after 9 p.m. tended to gain more body fat between the ages of 2 and 6. Compared with kids who had earlier bedtimes, they had bigger increases in both waist size and body mass index (BMI) — an estimate of body fat based on height and weight. The findings do not prove that later bedtimes cause excess weight gain, said Dr. Nicole Glaser, who wrote a commentary accompanying the study, which was published online Feb. 18 in Pediatrics. But the report adds to evidence linking sleep habits to kids’ weight, according to Glaser, a pediatric endocrinologist at the University of California, Davis. Specifically, studies have found higher rates of obesity among kids who either get too little sleep or have trouble falling or staying asleep. “At this point, I think it’s clear that there is a relationship between [sleep quality and obesity risk],” Glaser said. “The big question is whether the relationship is a causal one.” Dr. Claude Marcus, senior researcher on the study, agreed. “The causality is difficult to establish,” he said. Kids’ sleep habits do not exist in a vacuum, and it’s possible that other factors cause both late… read on >

Bedtime without your partner on Valentine’s Day could make sleep elusive. But a new study suggests one remedy: Cuddling up with a piece of his or her clothing. Researchers say having a loved one’s natural scent nearby could be as effective a sleep aid as melatonin. “One of the most surprising findings is how a romantic partner’s scent can improve sleep quality even outside of our conscious awareness,” said study senior author Frances Chen. She’s an associate professor of psychology at the University of British Columbia (UBC) in Vancouver. For the study, 155 people were given two T-shirts to use as pillowcases. One had been worn by their lover; the other was clean or had been worn by a stranger. While the participants’ partners were wearing the shirts, they were told not to use deodorant or scents or do anything that might affect their body odor, such as smoking, exercising and eating certain foods. The T-shirts were frozen to preserve their scent. Participants spent two nights in a row sleeping with each shirt. They weren’t told which shirt was which, but they reported feeling more well-rested after using the T-shirt with their lover’s scent. Data from sleep monitors confirmed it. “Our findings provide new evidence that merely sleeping with a partner’s scent improves sleep efficiency. Our participants had an average sleep efficiency improvement of more… read on >

If you need more than two hands to count the number of lovers you’ve had in your life, new research suggests you might want to worry about your cancer risk. People who have had 10 or more sexual partners had higher odds of being diagnosed with cancer than those who were less sexually active, researchers report. Women with that many sex partners had nearly double the risk of developing cancer as women who remained virgins or only had one sexual partner, the study found. Meanwhile, men’s odds of a cancer diagnosis were increased by nearly 70% compared with those reporting one or no sex partners, and by 57% for those who had two to four sex partners during their life. “We expected there to be an association between number of sexual partners and cancer risk as previous research has shown that specific sexually transmitted diseases may lead to several cancers,” said study co-author Lee Smith, director of research at the Cambridge Centre for Sport and Exercise Sciences at Anglia Ruskin University in England. “Indeed, a higher number of sexual partners means greater potential exposure to STIs [sexually transmitted infections]. “It is interesting that the risk is higher in women when compared to men,” Smith continued. “This may be because the link between certain STIs and cancer is stronger in women, such as HPV and cervical… read on >

MONDAY, Feb. 10, 2020A single dose of the human papillomavirus (HPV) vaccine works as well as multiple doses to protect older teen girls against preinvasive cervical disease, which can develop into cervical cancer, researchers say. For the study, the researchers analyzed data on more than 133,000 females aged 9 to 26. Half weren’t vaccinated and half received one or more HPV vaccine doses between January 2006 and June 2015. Among 15- to 19-year-olds, those who were vaccinated had lower rates of preinvasive cervical disease than those who weren’t, the findings showed. Within five years, about 2.6% of those who weren’t vaccinated developed preinvasive cervical disease, compared with less than 2% who had received one shot or more, according to the report. The risk of preinvasive cervical disease was 36% lower for those who had one shot, 28% lower after two shots and 34% lower for those who had three doses, compared with those who weren’t vaccinated. For the youngest (9 to 14 years) and oldest (20 to 26 years) age groups, there were no significant differences in risk for preinvasive cervical disease, according to the study published online Feb. 10 in the journal Cancer. “This study shows the impact of vaccinating at younger ages and its lasting long-term protection against cervical cancer,” said study author Dr. Ana Rodriguez. She’s an associate professor of obstetrics and… read on >

Migraine drugs that might work for adults won’t prevent the debilitating headaches in kids and teens, a new study shows. A number of drugs are used to prevent migraines, but treatment of youngsters has largely been based on the results of adult studies, the international team of researchers pointed out. What really works in kids? To find out, the researchers reviewed 23 studies conducted between 1967 and 2018. In total, these studies included more than 2,200 young patients. About one-quarter of these patients received an inactive placebo, while the remainder were treated with a range of drugs (antiepileptics, antidepressants, calcium channel blockers, blood pressure drugs) or food supplements. None of the medications were more effective than placebo in the long term (five to six months or longer), and only two — propranolol and topiramate — provided benefits in the short term (less than 5 months), according to the study published online Feb. 10 in JAMA Pediatrics. The bottom line, according to researcher Cosima Locher: “The preventive pharmacological treatment of pediatric migraine with all these drugs is barely more effective than placebo.” Locher is with the faculty of psychology at the University of Basel, in Switzerland. The findings highlight the need for more research into migraine prevention in children and teens, and into the power of the “placebo effect” specifically in these patients, the researchers said.… read on >

While fewer Americans are smoking these days, the habit has remained stubbornly persistent among stroke survivors, new research shows. The researchers found that the prevalence of smoking among U.S. stroke survivors has not improved since 1999 and, as of 2016, stood at 26%. That’s in contrast to the trend among Americans in general, who are gradually leaving cigarettes behind. Between 1999 and 2016, the study found, the smoking rate among the overall population fell from about 25% to 19%. The findings are concerning, experts said, considering the fact that smoking is a major risk factor for stroke. And among stroke survivors, those who continue to smoke are more likely to have — or die from — a repeat stroke or a heart attack, according to lead researcher Dr. Neal Parikh. He is an assistant professor of neurology at Weill Cornell Medicine and NewYork-Presbyterian, in New York City. Parikh said that the study results point to a need to “prioritize” smoking cessation as part of stroke recovery. The findings are based on nearly two decades of data from an ongoing federal health survey. Among over 49,000 U.S. adults who participated between 1999 and 2016, just under 3% were stroke survivors. Over those years, the general smoking rate declined to a statistically significant degree, according to Parikh. In contrast, there was no significant change among stroke survivors:… read on >
