A fertility procedure that mixes genetic material from three people to prevent couples from having children with certain debilitating and potentially fatal inherited disorders is now legal in two countries: the United Kingdom and Australia.

Australia’s senate passed a bill on March 30 amending pre-existing laws to allow the procedure in certain circumstances.

The goal of this procedure is to prevent genetic disorders caused by defective mitochondria, the power plants inside our cells that provide energy for normal growth and development. When mitochondria don’t produce any energy at all, the resulting genetic disorders are quickly fatal. When mitochondria make only a little energy, children can have severe illnesses and disabilities.

“The outcomes from this problem are really severe, and it’s highly likely that the baby will be very sick or die,” says Arthur Caplan, PhD, head of the division of medical ethics at the New York University Grossman School of Medicine.

Mitochondria have a little bit of DNA, and children inherit them from their mother. To avoid children inheriting this damaged genetic material, mitochondrial donation, also known as three-parent in vitro fertilization (IVF), takes the nucleus, which contains most of the DNA that makes us who we are, from an egg of the mother and puts it into a donated egg from a woman with healthy mitochondria.

The egg is then fertilized with sperm through IVF, and the resulting embryo has genetic material from two women and one man.

One ethical conundrum about mitochondrial donation is that any child conceived this way would inherit modified DNA and pass that along to their own children.

“I think it’s likely that we are going to go down this road to repair disease,” Dr. Caplan says. “I don’t think all genetic engineering of embryos is wrong, but we have to draw the line between enhancement versus treating disease.”

For couples who want a child that shares at least some of their own DNA, there are other ways to have a child without damaged mitochondria. One option would be genetic screening of their embryos to find healthy embryos without this defect, which would work for some women who have relatively few mitochondrial mutations. Another alternative is using a donor egg from a woman with healthy mitochondria.

Mitochondrial donation may appeal to couples who want their children to have a genetic connection to both parents, Dr. Caplan says. But prospective parents also need to be aware that this procedure is relatively new and, unlike egg donation, doesn’t have a long track record of success.

“It looks promising, but we don’t have the full safety picture yet, and we’re not going to start to get it for another decade or so,” Dr. Caplan cautions. “I do think it’s worth offering as one option, but you also have to get people to think about how important it is to have a biological child together and make sure that they understand that even if we try this technique, we don’t know the long-term outcomes for children yet.”

An adult brain contains about 86 billion neurons and even more supercomputing power to closely monitor the entire human brain.

All those neurons have trillions of synapses – or connection points – that make up the circuitry the brain uses to control everything we do from reasoning to breathing to walking. And scientists with the Human Brain Project are trying to build new computing tools that can zoom in on every one of these synapses, peer inside cells, and zoom out to focus on entire regions of the brain at once.

Imaging the human brain at the cellular level would require several petabytes of data, researchers from the Human Brain Project report in Science. If you have an old smartphone or tablet with 32GB of storage, you’d need more than 31,000 of them to get a single petabyte of storage.

Using an electron microscope to image the entire brain would require more than one exabyte of data, the scientists point out. That’s more than a million petabytes.

Giacomo Indiveri, PhD, professor of neuroinformatics at the University of Zurich, Switzerland, says we need to fundamentally change the way we build computers. Delivering the keynote address at the Human Brain Project Summit in October, he warned we will use 20% of all the world’s electricity on computing by the year 2025.

To meet the computing challenges posed by the quest to map every bit of the human brain, researchers are working to produce the first two exascale supercomputers within the next 5 years. When they’re done, these machines will provide brain scientists with supercomputers powerful enough to explore the human brain in all its complexities.

Giving birth may be so arduous for humans in part because the pelvis is optimized for standing upright, a new study suggests.

The study, published in BMC Biology , relies on computer-based simulations of how bone, soft tissue, and skin work in concert as we move. The same approach has been used to identify key elements of a perfect fastball in baseball and the best marathon gait.

In the new analysis, scientists used digital images to examine how bones and muscles around the pelvis move during daily activities and giving birth. Because the shape of the human pelvic canal doesn’t make for a fast or easy birth, the investigators wondered if its dimensions were linked to some other human feature.

In apes, this canal is a simple oval throughout, so labor and delivery might be easier for these species, the scientists note. But the oval in the human canal changes direction through the pelvis, requiring babies to rotate during delivery so that the head and shoulders can pass through.

Computer modeling with digital images suggested that the stress and pressure of being upright on two legs might give the pelvic canal its twist. When the researchers used a consistently oriented oval, like the one that apes have, the pelvis tilted and destabilized the spine, making it harder to balance on two legs.

Our balance might be even better with a widened outlet at the lower portion of the birth canal, the investigators found. But a wider outlet could make childbirth injuries more likely because it would require an even harder twist of the head and shoulders in the canal. The authors say that the shape of the pelvic canal could represent an “evolutionary compromise” between these competing factors.

These findings rely on computer models using digital images and don’t precisely recreate either the evolutionary or birthing process. But they do offer another feature to consider when answering the question of why human labor and delivery are so difficult, compared with our closest living cousins.

Trick-or-treaters may not be so easily tricked into loving sugar-free treats, thanks to taste buds hard-wired to seek calorie-containing sweets, a new study suggests.

Taste isn’t all about choosing peanut butter cups over jelly beans. Since earliest humanity, our sense of taste has helped us detect salty, sweet, sour, savory, and bitter so that we can choose foods high in energy and low in poisons.

But these new findings suggest that our taste buds have another hidden talent: identifying foods that don’t give us any energy at all.

Scientists suspected this ability after research in mice showed that their taste buds could distinguish between sugar and calorie-free artificial sweeteners.

To test this possibility in humans, scientists asked people to drink a series of clear beverages and identify whether they were plain water or sweetened. The goal was to compare how people responded to glucose – a natural caloric sweetener in fruits, honey, and table sugar – and sucralose, a calorie-free artificial sweetener.

All participants wore nose plugs, ensuring that they would use only their taste buds and not their sense of smell for detection.

As expected, people could easily tell plain water from sweetened drinks, whether with glucose or sucralose, confirming that taste buds detect sweetness.

In a twist, researchers then mixed in flavorless chemicals that block taste buds from picking up sweetness. With these drinks, people could no longer distinguish sucralose-sweetened beverages from plain water. But they could still tell when they had a beverage sweetened with glucose.

This finding indicates that two separate pathways underlie the mouth’s response to sugar, researchers report in PLOS One. The first pathway identifies sweet flavors, and the second one detects foods that contain energy that can be used for fuel.

Scientists might one day come up with calorie-free sweets that trick taste buds into detecting the presence of calories, enhancing their appeal. But in the lab studies, the participants had no visual cues or smell to guide their reactions, meaning how these other sensory inputs would affect treat perception isn’t known.

After a heart attack, the damaged area of the heart often becomes scar tissue that can’t receive electrical messages to contract and pump blood to the body. The result is a weakened heart that could get an irregular beat, known as an arrhythmia, or go into failure.

Right now, doctors have two imperfect options for repairing this damaged tissue. One is to surgically implant a scaffold that conducts electrically and bridges the heart’s signaling system past the dead tissue. But these implants require open-chest surgery, which is risky and can lead to other heart problems.

Clinicians can use an approach that avoids opening the chest, but the patch used for these procedures may not hold its shape when grafted to damaged tissue.

Now, scientists may be working on a fix that promises the best of both worlds: an injectable patch that conducts electricity and keeps its shape once grafted to heart muscle.

The patch hasn’t been tested in humans -- any such trials are still a long way off -- but early results in animals show potential.

This experimental patch can be rolled up, threaded into a catheter or a syringe, and injected into damaged heart tissue, where it unfurls and attaches to the muscle. Once in place, the patch supports normal heart function, according to results from studies using rats and pigs. The findings were published in Nature Biomedical Engineering.

When researchers placed the patch on damaged heart muscle in rats, they found this fix resulted in a return to mostly normal heart function within 4 weeks. Results were similar when scientists tested the patch in a small number of pigs, which are considered to resemble humans more closely than rodents.

The patched hearts did a better job in pumping oxygen-rich blood to the body, and the amount of heart tissue that wasn’t getting enough oxygen also declined.

(Reuters Health) - The proportion of U.S. babies born suffering from withdrawal syndrome after exposure to heroin or prescription opiates in utero has more than doubled in less than a decade, a study suggests.

Nationally, the rate of neonatal abstinence syndrome involving mothers' use of opiates - which includes heroin as well as prescription narcotics like codeine and Vicodin - surged from 2.8 cases for every 1,000 births in 2009 to 7.3 cases for every 1,000 births in 2013, the study found.

At least some of this surge in the case count is due to drug policies designed to crack down on prescription drug abuse and combat the methamphetamine epidemic, said lead study author Dr. Joshua Brown, a pharmacy researcher at the University of Kentucky in Lexington.

"The drug policies of the early 2000s were effective in reducing supply - we have seen a decrease in methamphetamine abuse and there have been reductions in some aspects of prescription drug abuse," Brown said by email. "However, the indirect results, mainly the increase in heroin abuse, were likely not anticipated and we are just starting to see these."

The findings of the current study add to a growing body of evidence pointing to a surge in births of babies suffering from opiate withdrawal. One report last month from the U.S. Centers for Disease Control and Prevention found an even bigger spike over a longer period, from 1.5 cases for every 1,000 births in 1999 to 6 cases per 1,000 in 2013.

CDC researchers also found wide variation in neonatal abstinence syndrome by state, ranging in 2013 from 0.7 cases for every 1,000 births in Hawaii to 33.4 cases per 1,000 in West Virginia.

"We know that certain states are harder hit by the opioid/heroin abuse epidemic, with about 10 states contributing half of all neonatal abstinence syndrome cases," Brown said. "These states are often more rural and impoverished areas of the U.S. such as Mississippi, Alabama, and West Virginia."

Brown and colleagues looked at Kentucky in particular. Here, the rate of neonatal abstinence syndrome climbed from 5 cases for every 1,000 births in 2008 to 21.2 cases per 1,000 births in 2014, researchers report in JAMA Pediatrics, online September 26.

While the study didn't look at health outcomes for babies born suffering from drug withdrawal, these infants often require intensive medical care. (See Reuters' 2015 special report "Helpless and Hooked" here.)

These babies may have central nervous system issues like seizures and tremors, gastrointestinal problems and feeding difficulties, breathing challenges, as well as unstable body temperatures.

Typically, they remain in the hospital for several weeks after birth and receive low doses of methadone, Brown said.

Treatment can ease withdrawal symptoms in newborns, but can't necessarily address developmental problems these infants may have later on, said Dr. William Carey, a pediatrics researcher at pediatrics at Mayo Clinic Children's Center in Rochester, Minnesota.

"While abuse of prescription opiates has declined, the use of illicit opiates has increased such that there may be a zero-sum game at best," Carey, who wasn't involved in the study, said by email. "Since maternal use of either prescription opiates or illicit opiates is associated with withdrawal in newborns, it is reasonable to think that any increase in the overall use of opiates would be linked to an increase in the rate of neonatal abstinence syndrome."

Brown and colleagues looked at Kentucky in particular. Here, the rate of neonatal abstinence syndrome climbed from 5 cases for every 1,000 births in 2008 to 21.2 cases per 1,000 births in 2014, researchers report in JAMA Pediatrics, online September 26.

While the study didn't look at health outcomes for babies born suffering from drug withdrawal, these infants often require intensive medical care. (See Reuters' 2015 special report "Helpless and Hooked" here.)

These babies may have central nervous system issues like seizures and tremors, gastrointestinal problems and feeding difficulties, breathing challenges, as well as unstable body temperatures.

Typically, they remain in the hospital for several weeks after birth and receive low doses of methadone, Brown said.

Treatment can ease withdrawal symptoms in newborns, but can't necessarily address developmental problems these infants may have later on, said Dr. William Carey, a pediatrics researcher at pediatrics at Mayo Clinic Children's Center in Rochester, Minnesota.

"While abuse of prescription opiates has declined, the use of illicit opiates has increased such that there may be a zero-sum game at best," Carey, who wasn't involved in the study, said by email. "Since maternal use of either prescription opiates or illicit opiates is associated with withdrawal in newborns, it is reasonable to think that any increase in the overall use of opiates would be linked to an increase in the rate of neonatal abstinence syndrome."

(Reuters Health) - The proportion of U.S. babies born suffering from withdrawal syndrome after exposure to heroin or prescription opiates in utero has more than doubled in less than a decade, a study suggests.

Nationally, the rate of neonatal abstinence syndrome involving mothers' use of opiates - which includes heroin as well as prescription narcotics like codeine and Vicodin - surged from 2.8 cases for every 1,000 births in 2009 to 7.3 cases for every 1,000 births in 2013, the study found.

At least some of this surge in the case count is due to drug policies designed to crack down on prescription drug abuse and combat the methamphetamine epidemic, said lead study author Dr. Joshua Brown, a pharmacy researcher at the University of Kentucky in Lexington.

"The drug policies of the early 2000s were effective in reducing supply - we have seen a decrease in methamphetamine abuse and there have been reductions in some aspects of prescription drug abuse," Brown said by email. "However, the indirect results, mainly the increase in heroin abuse, were likely not anticipated and we are just starting to see these."

The findings of the current study add to a growing body of evidence pointing to a surge in births of babies suffering from opiate withdrawal. One report last month from the U.S. Centers for Disease Control and Prevention found an even bigger spike over a longer period, from 1.5 cases for every 1,000 births in 1999 to 6 cases per 1,000 in 2013.

(Reuters Health) - Some cancer patients may turn down care that could ease their pain and improve their quality of life because they think this type of "palliative" treatment amounts

to giving up and simply waiting to die, a small Canadian study suggests.

Even though the World Health Organization recommends early palliative care for patients living with any serious illness, negative attitudes among patients and family caregivers often lead them to reject this option, researchers note in the Canadian Medical Association Journal.

"Patients and caregivers in our study saw palliative care as being equated with death, loss of hope, dependency, and going into places you never get out of again," said lead study author Dr. Camilla Zimmermann, head of the division of palliative care at the University Health Network in Toronto.

"This is in stark contrast with the actual definition of palliative care, which is interdisciplinary care that provides quality of life for patients with any serious illness and their families, and that is provided throughout the course of the illness rather than only at the end of life," Zimmermann added by email.

Zimmermann and colleagues interviewed 48 cancer patients and 23 of their family caregivers in cases when life expectancy was six to 24 months.

The researchers randomly assigned 26 patients to receive palliative care in addition to standard cancer care, while another 22 patients had only standard care.

Twenty-two patients in the palliative care group and 20 in the control group were receiving chemotherapy.

Over four months, patients in the palliative care group had at least monthly palliative care clinic visits, while those in the standard care group didn't receive any formal interventions. Caregivers could attend clinic visits for the palliative care participants, but they weren't required to do so.

Patients were typically in their early to mid 60s. Most were married and had at least some education beyond high school.

Most family caregivers were spouses, but a few were children or other relatives.

Initial perceptions of palliative care were similar in both groups - patients generally thought this was done only for the dying. While patients in both groups thought of palliative care

as providing comfort, they also associated it with giving up on treatment.

Once some patients received palliative care, however, their thinking shifted. Some patients now saw this as a way to live life to the fullest despite the terminal diagnosis, while others

suggested that doctors might have better luck renaming this as something other than "palliative care."

Calling palliative care providers "pain specialists" because they treat discomfort and focus on quality of life would make this sound more appealing and less frightening, some patients

said after getting this type of care.

But in the control group, without any experience with palliative care during the study, patients didn't see the point of renaming it because they thought it would still carry the stigma of giving up and waiting to die.

"Palliative care should not be framed as a last resort option," said Dr. Anthony Caprio, a geriatrician and hospice and palliative medicine physician at Carolinas HealthCare System in

North Carolina.

"These `nothing left to do' conversations often frame palliative care as a way to help people die comfortably, rather than an approach to care that allows them to live with the highest quality of life for as long as possible," said Caprio, who wrote an editorial that was published with the study.

Using different language in discussions with patients can make a big difference, Caprio added.

"I often describe palliative care as an extra layer of support," Caprio said. "Who wouldn't want more support, especially during a difficult illness?"

(Reuters Health) - When it comes to urgent medical problems like ankle injuries or suspected strep, virtual MDs may be no match for the real thing, a new U.S. study suggests.

Researchers enlisted 67 volunteers to test out how well eight popular virtual visit companies diagnosed these problems and four other common medical issues - sore throat, sinus infection, low back pain, and urinary tract infection.

About one in four patients got the wrong diagnosis or none at all from the virtual visits, the study found. What's more, virtual doctors followed standard protocols for diagnosing and treating these problems only 54% of the time.

"One of the more surprising findings of the study was the universally low rate of testing when it was needed," said lead researcher Dr. Adam Schoenfeld, of the University of California, San Francisco.

"We don't know why, but it may reflect the challenges of ordering or following up on tests performed near where the patient lives but far from where the doctor is, or concern about the costs to the patient of additional testing," Schoenfeld added by email.

Virtual visits using videoconferences, phone calls and web chats are becoming a more common way for patients to seek urgent care because it can save the inconvenience of a clinic visit or provide access to care when people can't get an appointment with their regular doctor.

Some insurers are starting to pay for virtual visits in certain situations, making this option more viable for patients who worry about costs.

For the current study, Schoenfeld and colleagues trained volunteers to act as if they had common acute medical problems and then sent them to virtual doctors provided by companies including Ameridoc, Amwell, Consult a Doctor, Doctor on Demand, MDAligne, MDLIVE, MeMD and NowClinic.

Altogether, the volunteers completed 599 virtual visits in 2013 and 2014.

The companies varied in how well they followed treatment guidelines, with standard care given anywhere from 34 to 66% of the time across the eight websites, the researchers report in JAMA Internal Medicine April 4.

Mode of communication - such as web chat or videoconference - didn't appear to influence how often treatment guidelines were

followed.

Virtual doctors got complete histories and did thorough exams anywhere from 52% to 82% of the time.   Virtual visits resulted in correct diagnoses anywhere from 65% to 94% of the time.

Often, virtual doctors failed to order urine tests needed to assess urinary tract infections, or to request images needed to diagnoses ankle pain, for example, and antibiotics were often prescribed inappropriately.

One limitation of the study is that the researchers only looked at virtual visits, so they couldn't compare these online doctors' visits to what might have happened with in-person clinical exams.

Still, it's possible that at least some of the variation in quality of care was the result of the remote visits, said Dr. Jeffrey Linder, a researcher at Brigham and Women's Hospital and Harvard Medical School who co-authored an editorial accompanying the study.

"There is a built-in barrier to getting testing, which led to worse care for ankle pain and recurrent urinary tract infections - for which the doctors should have ordered a test - and better care for low back pain - for which doctors should not have ordered a test," Linder said by email.

In an ideal world, patients would be able to have occasional virtual visits with their primary care providers, who know their medical histories, said Dr. David Levine, co-author of the editorial and also a researcher at Brigham and Women's and Harvard.

Although virtual urgent care and in-person urgent care have not been compared head-to-head, virtual urgent care has its downsides - indirect physical exam, difficult access to testing, and unclear follow-up," Levine said by email. "While the quality of care is not perfect anywhere, a patient's primary care doctor should be a person's first point of contact."

(Reuters Health) - Kids who live in a stress-free environment may grow up to be adults with a lower risk of heart attacks than their peers who experience social, emotional or financial difficulties during childhood, a Finnish study suggests.

Researchers assessed psychosocial factors in 311 kids at age 12 and 18. Then, at age 28, they looked for coronary artery calcification.

The adults who had high psychosocial wellbeing as kids were 15% less likely to have calcium deposits clogging their arteries as adults, the study found.

"This study suggests that childhood psychosocial factors may have long-term consequences on cardiovascular health," lead study author Dr. Markus Juonala of the University of Turku in Finland said by email.

To understand the connection between how kids feel growing up and how their arteries look decades later, Juonala and colleagues analyzed data gathered from 1980 to 2008 as part of the Cardiovascular Risk in Young Finns Study.

Among other things, this study measured psychosocial wellbeing by looking at family income and education levels, parents' job status, parents' mental health and history of smoking or substance abuse, parents' weight and exercise habits, stressful events such as divorce, death or moves, as well as the child's level of aggressive or anti-social behaviors and ability to interact with other people.

In addition, researchers analyzed results from computed tomography (CT) scans assessing coronary artery calcification. Overall, 55 participants, or about 18%, had at least some calcification in their arteries, researchers report in JAMA Pediatrics, March 14.

Among this group with calcification, 28 participants had low levels of buildup, 20 had moderate amounts of calcium and 7 had substantial deposits, the study found.

Even after accounting for adult circumstances like psychosocial factors and risk factors for heart disease like obesity, smoking, hypertension and elevated cholesterol, the research team still found well-being during childhood was associated with reduced coronary artery calcification in adulthood.

The study is observational and doesn't prove childhood stress causes clogged arteries or heart attacks, only that the two things are related, the authors note.

It's possible, however, that stress during childhood might trigger changes in metabolic functioning and inflammation that later contribute to calcium deposits in the arteries, the researchers point out.

It's also possible that happier kids may develop healthier habits like better diets and more rigorous exercise routines that help keep arteries unclogged and lower their risk of heart disease later in life.

"The take-home message for parents is to understand that stress in childhood may have many adverse effects and that they should help their children avoid stress," said Dr. Stephen Daniels, a researcher at the University of Colorado School of Medicine and pediatrician-in-chief at Children's Hospital Colorado.

Parents may not always be able to eliminate stress, however, particularly the stress that can come from environmental factors like lower socioeconomic status, Daniels, who wasn't involved in the study, added by email.

When children grow up with stress, they can still take charge of their health as adults to lower their risk of heart disease, Daniels noted.

"For an adult who had a stressful childhood, the best approach is to be aware of their cardiovascular risk status and to reduce their risk by improving diet and physical activity and avoiding cigarette smoking," Daniels added. "Where risk factors exist, such as high blood pressure, they should be appropriately treated."

Parents may not always be able to eliminate stress, however, particularly the stress that can come from environmental factors like lower socioeconomic status, Daniels, who wasn't involved in the study, added by email.

When children grow up with stress, they can still take charge of their health as adults to lower their risk of heart disease, Daniels noted.

"For an adult who had a stressful childhood, the best approach is to be aware of their cardiovascular risk status and to reduce their risk by improving diet and physical activity and avoiding cigarette smoking," Daniels added. "Where risk factors exist, such as high blood pressure, they should be appropriately treated."

(Reuters Health) - Elderly patients hospitalized for cancer surgery are more likely to have complications afterward compared to the middle-aged, particularly when they have several other health problems, a U.S. study suggests.

Overall, almost one in 10 adults age 55 and older had at least one post-operative issue like delirium, dehydration, falls, fractures, pressure ulcers or unusual weight loss, the study of nearly 1 million cancer surgery patients found.

These setbacks were even more common when patients were at least 65 years old, had two or more other serious health problems in addition to malignancies, or had surgeries for tumors of the digestive system or nearby organs.

But the odds were worst for people over 75 - about 46 percent of them had at least one complication, compared with 22 percent of adults aged 55 to 64.

"With the population aging, it's becoming increasingly important to consider not only the survival benefits of cancer surgery but the impact on functionality, vitality and quality of life," said lead study author Dr. Hung-Jui Tan, a researcher in urologic oncology at the University of California, Los Angeles.

While the events studied here are specific to the initial hospitalization, they can carry potential long-term ramifications," Tan added by email.

To see how age influences the risk of post-operative complications, Tan and colleagues reviewed hospital admission records for a nationwide sample of 940,000 adults age 55 and older who had cancer surgery from 2009 to 2011.

Compared with patients who were under age 65, those who were 65 to 74 years old were 23 percent more likely to have complications, while the over-75 group had 66 percent higher odds, researchers report in the Journal of Clinical Oncology.

Complications were most likely when patients were having surgery for cancers of the bladder, ovary, colon, rectum, pancreas or stomach.

After suffering post-operative setbacks, patients were also more likely to have further complications during their hospital stay, to remain in the hospital longer and to have more costly care. They were also more likely to die in the hospital and less likely to be discharged to home.

One limitation of the study is its reliance on administrative claims data, which is designed for billing purposes and might not always reflect the nuances of patients' medical conditions, the authors note. In addition, it's possible that some complications may have resulted from conditions patients had before they arrived at the hospital for cancer surgery.

The study can't prove that advanced age directly causes post-operative problems. But the findings suggest doctors and patients should consider these potential risks when deciding the best course of treatment, Tan said.

Patients should also understand that not all complications are equally devastating to quality of life. Dehydration and weight loss, for example, are nutritional problems that might be treated with fluids, noted Dr. Siri Rostoft, a geriatric medicine researcher at Oslo University Hospital in Norway.

"Cancer is often a lethal disease if left untreated that causes conditions such as bleeding, obstruction of the intestines, and pain," Rostoft, who wasn't involved in the study, said by email. "Not treating patients may be worse for their quality of life than operating."

Still, the findings add to a growing body of data on post-operative complications that may help doctors and patients decide if the potential benefits of surgery outweigh the possible risks, Dr. Steven Cunningham, a researcher at Saint Agnes Hospital and Cancer Institute in Baltimore who wasn't involved in the study, said by email.

Complications in the study were more likely at non-teaching hospitals and facilities that did fewer cancer surgeries, a factor that patients should also consider when they have a choice about where to go for surgery, noted Dr. Kwok-Leung Cheung, a researcher at the University of Nottingham in the U.K. and member of the surgical task force for the International Society of Geriatric Oncology.

Knowing when not to operate also matters, Cheung, who wasn't involved in the study, added by email.

"The surgeon should seriously consider the intensity of surgery, which has been identified as one of the important factors with post operative problems," Cheung added. "The use of minimally invasive techniques including laparoscopic and robotic surgery should be considered wherever appropriate."
