Magnesium Could Prevent Fractures in Elderly

You should be adding a magnesium supplement to your daily vitamin regimen in middle age to prevent fractures later, says a new study.

Bone fractures, which are often caused by osteoporosis, are one of the leading causes of disability in the elderly. Calcium and vitamin D are known to play a role in bone health, and while magnesium is a vital nutrient and an important component of bone, no studies have shown that supplements might have a beneficial effect on bone health.

Researchers at the Universities of Bristol and Eastern Finland followed 2,245 middle-aged men for 20 years. They found that men with lower blood levels of magnesium had an increased risk of fractures, particularly fractures of the hip.

Men who had higher blood levels of magnesium lowered their risk by 44 percent. None of the men who had very high magnesium levels suffered a fracture during the 20-year follow-up.  

However, dietary magnesium intake was not found to be linked with fractures. Only supplements were shown to be beneficial.

“The findings do suggest that avoiding low serum concentrations of magnesium may be a promising though unproven strategy for risk prevention of fractures,” said Dr. Setor Kunutsor of the University of Bristol.

Low blood levels of magnesium are common among the middle-aged and elderly, since the mineral becomes harder for the body to absorb as it ages, but the majority of people have no symptoms. Since blood magnesium isn’t measured routinely in the hospital, those with low levels are usually not diagnosed. The researchers believe their findings could help trigger initiatives to include blood magnesium screening in routine blood panels, especially for the elderly.

Magnesium may also help solve another problem faced by seniors — getting a good night’s sleep. British researchers found that magnesium helps cells keep track of the natural cycles of day and night.

Other studies show that magnesium provides a wide range of health benefits, including boosting the immune system and lowering the risk of heart attacks. Studies have also shown that people who have migraines tend to have lower levels of magnesium than those who are headache free.

Nursing Home Residents Often Untreated for Chronic Pain

Many nursing home residents suffering from chronic pain don’t get any medication or don’t get enough to fully relieve their symptoms, a recent U.S. study suggests.

Researchers examined data on almost 1.4 million residents in nursing homes nationwide from 2011 to 2012 and found that overall, roughly two in five had either intermittent or chronic pain.

Among the residents with persistent pain, about 6 percent received no medication at all and another 32 percent didn’t get enough drugs to properly address their symptoms, the study found.

“The good news is that we documented lower levels of untreated pain than previous studies,” said lead study author Jacob Hunnicutt of the University of Massachusetts Medical School in Worcester.

“However, pain may still be undertreated and disparities in pain management by cognitive impairment and race/ethnicity remain,” Hunnicutt said by email.

Previous studies have estimated that at least 40 percent of nursing home residents experience persistent pain, and that 20 percent of those in pain don’t get any medications, researchers note in the journal Pain.

More than 1.4 million adults live in U.S. nursing homes, including about 3 percent of people over 65 and roughly 10 percent of people over 85.

For the current study, researchers examined data on nursing home residents who spent at least 100 days in the same facility with no gaps in residency of more than 30 days.

Residents provided information on the intensity and frequency of any pain they experienced as well as any medications provided during two assessments three months apart. Participants were counted as having persistent pain if they described pain on both assessments, and intermittent pain if they only mentioned it during one of the assessments.

If residents reported pain and didn’t have any scheduled or as-needed medications noted in their medical records, researchers counted them as having untreated pain. If their records only included as-needed pain medications, researchers counted them has having potentially undertreated pain.

Non-white residents were 19 percent more likely than white residents to have undertreated or untreated pain, the study found.

In addition, residents with severe cognitive impairments were 51 percent more likely to have untreated or undertreated pain than people with only mild impairments or none at all.

One of the study authors is a consultant with the pharmacy benefits manager and drugstore chain CVS Caremark.

Limitations of the study include the lack of data on pain levels between the two assessments, the authors note. Researchers also relied on residents to accurately recall and report on their own pain levels, which can be subjective.

The study also didn’t account for patient preferences or medical histories, said Dr. Gary Winzelberg, a geriatrics researcher at the University of North Carolina School of Medicine in Chapel Hill who wasn’t involved in the study.

“It’s possible that some patients prefer not to receive pain medications and may use non-pharmacologic approaches to managing their pain,” Winzelberg said by email.

Some residents might not believe they should report being in pain or think they shouldn’t take medications. This might at least partially explain why older adults, men and residents of color were less likely to report pain and receive medications, Winzelberg added.

Residents and families can see how nursing homes compare on pain management and other quality measures online, Hunnicutt said.

To avoid untreated pain, residents and their loved ones shouldn’t be shy about speaking up, said Dr. XinQi Dong of the Rush Institute for Healthy Aging in Chicago.

“Patients and family should seek help when the pain is beginning to rise, and not to wait until pain is intolerable before asking for pain medications,” Dong, who wasn’t involved in the study, said by email.

“After adequate assessment, health care professionals should provide an adequate mixture of long acting and short acting pain medications for those with chronic and inadequately treated pain,” Dong added.

Boost in Steroid Use Among Older Men

by Dr Alex Jimenez DC, APRN, FNP-BC, CFMP, IFMCP | Anti Aging

Middle-aged men jonesing for a boost in vitality are turning to steroids in increasing numbers, say researchers and health professionals. Men in their 40s, 50s — even 60s and 70s — are turning to hormones to fight the effects of aging, including weight gain and decreased libido, according to The Guardian.

Joseph Kean, a visiting research fellow at Liverpool John Moores University, said that usage has doubled in the number of men 50 and over in the past five years. He told The Guardian, “Guys are saying they just want to stand a bit taller and feel they can stand alongside the younger generation who are much more aware of how they look.”

But the vision of a buffer, more energized you comes with caveats — including the potential for worsening sleep apnea, heart disease, blood clots, and prostate complications.

Testosterone levels decline early on, starting at around age 30. This drop can lead to any number of unwanted side effects and problems, according to the National Center for Biotechnology Information at the National Institutes of Health. Low-T as it is often referred to, is responsible for much more than just weight gain and decreased sex drive. It is correlated with insulin resistance, low muscle strength and development — even poor cognitive function. So it’s a given that men would want to head off this decline and preserve their vigor for as long as possible.

“We have come across a lot of older men using [steroids]. It’s almost like hormone replacement therapy [for menopause relief] for females. Steroids can help you lose body fat as well,” Julien Baker, an applied physiology professor at the University of the West of Scotland, told The Guardian. “The evidence isn’t there about what the long-term impact is yet. We are not sure what these drugs are doing to you at that age, but everyone perceives it as safe.”

Magazines geared toward rejuvenation through hormone replacement have sprung up, as have clinics that promote testosterone replacement therapy in the United States and abroad.

The Juice Clinic in Sheffield, England, is one such service for people using steroids and image-enhancing drugs. Sid Wiffen, the clinic’s team leader, told The Guardian he has noted an increase in older men asking for help. “Steroid use for older men is often about the youthful effects, and about body image and energy levels. I hear talk of men feeling more pressure now to look good, so they are more likely to go to the gym and dress well,” he said. “It can be dangerous, and it does worry me. Lots of people we see are keen to make an informed decision about their steroid use, but some get information elsewhere and it’s not always good.”

That elsewhere includes the internet of course, where misinformation on the topic flourishes. The healthier, safer route by far is to seek the advice of a physician and get a prescription.

Steroids, officially known as anabolic-androgenic steroids, were first developed for medical use in wasting conditions. Their possession or sale without a prescription is illegal in the United States, though some people are able to get them online or in gyms. Some countries permit legal possession, including the U.K., though it is illegal to supply them there. Steroids come in pill form, injectables (intramuscular), and topical gels.

Baker said while there could be some benefits for older men, the risks should be well understood. “Introducing something your body stopped producing naturally may lead to repercussions or have health implications,” he said. “There’s not enough research out there to look at that. Someone taking steroids at 50 — it’s not clear what might happen to them in the future.”

Once users discontinue the use of steroids, many report withdrawal symptoms such as low mood and anxiety, something men should keep in mind as well.

Good Sleep Gets Tougher With Age

by Dr Alex Jimenez DC, APRN, FNP-BC, CFMP, IFMCP | Anti Aging

Most people see their sleep habits shift as they age, but a new review suggests that some seniors lose the ability to get deep, restorative rest.

And that can come with health consequences, said review author Bryce Mander, a sleep researcher at the University of California, Berkeley.

Sleep “fragmentation” has been linked to a number of medical conditions, including depression and dementia, Mander said. People with fragmented sleep wake up multiple times during the night, and miss out on the deep stages of sleep.

It is true that medical conditions, or the treatments for them, can cause sleep problems, according to Mander.

But poor sleep can also contribute to disease, he added.

Take dementia, for example. Research suggests there is a “bi-directional” link between sleep disruptions and the dementia process, said Joe Winer, another Berkeley researcher who worked on the review.

That is, dementia often causes sleep problems; poor sleep, in turn, may speed declines in memory and other mental skills. According to Winer, animal research suggests that deep sleep helps “clear” the brain of the amyloid-beta proteins that build up in people with dementia.

So there may be a “vicious cycle,” Winer said, where dementia and poor sleep feed each other.

Similar vicious cycles may be at work with other diseases, too, Mander said. He also stressed, though, that some shifts in sleep habits may be perfectly normal.

Older people are famously prone to being “early to bed, early to rise.” They may also sleep a little less than they used to in their younger days. And that may be fine, the researchers said.

“We don’t want to create a panic that if you’re sleeping a little less than you used to, you’re going to develop dementia,” Mander said.

But, he added, it is important to recognize sleep as one of the lifestyle factors critical to good health — right along with exercise and a healthy diet.

In fact, Mander noted, one reason that regular exercise keeps us healthy is that it can support better-quality sleep.

“Why do some people age more ‘successfully’ than others?” he said. “We think sleep is one of the factors.”

Dr. Sanjeev Kothare, a sleep specialist who was not involved in the study, said poor sleep “clearly” has health consequences.

Sleep apnea is a good example, said Kothare, of the NYU Langone Comprehensive Epilepsy-Sleep Center, in New York City.

Obstructive sleep apnea causes repeated stops and starts in breathing during the night, and it’s linked to major diseases, such as heart disease and diabetes. Research also suggests it can hasten declines in memory and thinking.

Dr. Phyllis Zee is chief of sleep medicine at Northwestern University in Chicago. She said sleep quality is more important than “duration.”

So if older people are sleeping a little less than they used to — or wake up once at night then quickly fall back asleep — that’s probably not a red flag, according to Zee.

But, she said, older adults should talk to their doctor if they routinely sleep less than six hours a night, or lack long “consolidated” blocks of sleep.

In some cases, Zee said, sleep apnea may be to blame.

In other cases, people may need lifestyle adjustments that can improve their sleep. The good news, Zee said, is that “behavioral and environmental changes are powerful.”

Older people can improve their sleep by fitting physical and social activity into their daily routine, Zee said. At night, she suggested they make sure the bedroom temperature is comfortable and limit exposure to artificial light — especially the blue glow of computer and TV screens.

Zee also stressed the importance of getting enough daylight, in the morning and afternoon: That helps keep the body’s circadian rhythms (the sleep-wake cycle) on track.

But people should not wait until old age to care about sleep. According to Mander’s team, people often start losing the capacity for deep sleep in middle age, and that decline continues over the years.

What’s not clear yet, Mander said, is whether good sleep habits earlier in life help protect people from sleep problems in old age.

The review, which analyzed medical literature on the topic of sleep and aging, was published online April 5 in the journal Neuron.

What's the Secret of 'SuperAgers?'

by Dr Alex Jimenez DC, APRN, FNP-BC, CFMP, IFMCP | Anti Aging

At 89, Donald Tenbrunsel is a bit of a phenomenon. He surfs the internet with ease, happily converses on a broad range of timely topics, volunteers and reads regularly.

Known as a “SuperAger,” Tenbrunsel was part of a study that helped researchers discover what factors might set these super-sharp seniors apart from their peers.

The secret? Brain scans showed they experience brain aging twice as slowly as average folks their age.

“This suggests the SuperAgers are on a different trajectory of aging,” said senior researcher Emily Rogalski. She is director of neuroimaging for Northwestern University’s Cognitive Neurology & Alzheimer’s Disease Center. “They’re losing their brain volume at a much slower rate than average agers.”

For the study, Rogalski and her colleagues measured brain aging by examining the thickness of each person’s cortex — the outer layer of folded gray matter in the brain.

The cortex is where consciousness lies, and where all of the neurons that fire thoughts and movements are located. It is a critical part of the brain for higher-level thinking, memory, planning and problem-solving, Rogalski said.

Another neurologist explained it this way:

“That is essentially our brain,” said Dr. Paul Wright, chair of neurology at North Shore University Hospital in Manhasset, N.Y., and Long Island Jewish Medical Center in New Hyde Park, N.Y. “Brain shrinkage occurs in the natural progression over time, and when you lose brain volume, you lose function.”

Rogalski noted that previous research has shown that the cortexes of SuperAgers look less worn than their average 80-year-old peers, and about the same as people in their 50s or 60s.

But a question remained — were the SuperAgers born with brains that have more volume, and thus could better withstand the travails of aging? Or are their brains the same size as everyone else’s, and simply aging less rapidly?

To answer that question, the researchers tracked changes in cortex thickness for a year and a half in 24 SuperAgers and 12 average elderly people.

Both groups lost a significant amount of brain volume to aging, but average elderly people experienced a loss more than twice that of the SuperAgers — over 2.2 percent versus 1.1 percent.

“Part of the reason why they may have different brain volumes is because over the decades they’ve been losing their brain volume at a different rate,” Rogalski said.

The findings were published April 4 in the Journal of the American Medical Association.

Dr. Ezriel Kornel, a neurologist with Weill Cornell Medical College in New York City, said that at least part of the brain advantage of SuperAgers is genetic, with some people simply gifted at birth.

But there are likely to be environmental influences that also contribute to healthier brain aging, particularly in the womb and in early childhood, Kornel added. For example, research has shown that children raised in poverty tend to have smaller brains.

“There are so many factors involved,” Kornel said. “It could be that even external stressors in childhood can influence how the brain develops.”

Rogalski said that future research will focus on genetic factors that influence brain aging, which hopefully will provide researchers with anti-aging “targets” that could be manipulated with medications or other therapies.

While there’s currently no proven method to preserve cortex volume, research has shown specific lifestyle changes that seniors can perform to help keep themselves sharp as they age, Kornel and Wright said. These include:

Regular physical exercise, including strength training.

A healthy and balanced diet.

Brain workouts that involve challenging puzzles or tasks.

An active social life.

“Everyone understands they’re going to die, but people don’t want to feel they’re losing their ability to think and be who they are,” Kornel said. “This is the next big frontier in science, to figure out how we can prevent overall deterioration of the brain.”
