Loving partners key to breast cancer survivor health

Published

on

A little romance may go a long way toward helping breast cancer survivors thrive.

New research showed that a strong romantic relationship wasn’t the cure-all, but it was linked to lower psychological stress and lower inflammation, which is a key to staying healthy.

“It’s important for survivors, when they’re going through this uncertain time, to feel comfortable with their partners and feel cared for and understood, and also for their partners to feel comfortable and share their own concerns,” said lead author Rosie Shrout, a postdoctoral scholar in the Institute for Behavioral Medicine Research at Ohio State University.

“Our findings suggest that this close partnership can boost their bond as a couple and also promote survivors’ health even during a very stressful time, when they’re dealing with cancer,” she said in a university news release.

For the study, 139 female breast cancer survivors, average age 55, completed questionnaires and gave blood samples.

One survey assessed relationship satisfaction. The other questionnaire evaluated their level of psychological stress.

Researchers analyzed blood samples for levels of proteins that aid inflammation. Inflammation is linked to heart disease, type 2 diabetes, arthritis and Alzheimer’s disease, among other conditions.

The more satisfied women felt about their romantic relationships, the lower their stress and inflammation, the researchers found.

“This gave us a unique perspective — we found that when a woman was particularly satisfied with her relationship, she had lower stress and lower inflammation than usual — lower than her own average,” Shrout said. “At a specific visit, if she was satisfied with her partner, her own inflammation was lower at that visit than at a different visit when she was less satisfied.”

Although the findings related to breast cancer survivors, Shrout believes a strong romantic relationship would be helpful to people with other serious illnesses by lowering their stress.

The report was published online recently in the journal Psychoneuroendocrinology.

Study: Common cold may help prevent flu, perhaps COVID-19

Published

on

Sept. 4 (UPI) — The virus most often behind the common cold is capable of preventing the flu virus from infecting airways by jump-starting the body’s immune defenses, a study published Friday by The Lancet Microbe found.

Now, the researchers from Yale University, want to determine if rhinovirus, the most common cold-causing virus, offers similar protective effects against COVID-19.

In an analysis of more than 13,000 patients with symptoms of a respiratory infection, those who had rhinovirus were not simultaneously infected with the flu virus — even during months when both viruses were active.

The finding may help explain why an expected surge in cases of H1N1 swine flu, predicted for Europe in fall 2009, never occurred, the researchers said.

It’s possible that the H1N1 virus was unable to infect those who already had the common cold, which was widespread at the time, they said.

“Infection with the common cold virus protected cells from infection with a more dangerous virus, the influenza virus, and [this] occurred because the common cold activated the body’s general antiviral defenses,” study co-author Dr. Ellen F. Foxman told UPI.

“This may explain why the flu season, in winter, generally occurs after the common cold season, in autumn, and why very few people have both viruses at the same time,” said Foxman, an assistant professor of laboratory medicine at Yale School of Medicine.

Concern has risen over the potential overlap of the COVID-19 pandemic with the annual flu season in the United States.

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, recently said that the level of new cases of the coronavirus across the country is “too high.”

If cases continue to rise as flu season approaches, Fauci said, people infected with either of the two viruses, or both, could overwhelm the U.S. healthcare system.

“There [have been] a few reports of influenza-COVID-19 co-infections earlier in the year, and many of us are quite concerned what an influenza epidemic added to the COVID-19 pandemic could do,” Dr. Tony Moody, an associate professor of pediatric infectious diseases and immunology at Duke University Medical Center, told UPI

“At this point, we don’t really know what the two diseases will look like, or if other respiratory viruses will help or hurt during the current pandemic,” said Moody, who was not part of the Yale research.

For this study, Foxman and her colleagues analyzed nasal and throat specimens collected from 13,707 people with evidence of a respiratory infection. Just over 7% of the specimens tested positive for the rhinovirus, while just under 7% had confirmed influenza A infection.

Only 12 people in the study population had evidence of both viruses simultaneously, the researchers found.

To test how the rhinovirus and the influenza virus interact, Foxman and her colleagues created human airway tissue with epithelial cells, which line the airways of the lung and are a chief target of respiratory viruses, grown from stem cells.

After the tissue had been exposed to rhinovirus, the influenza virus was unable to infect the tissue because the cells’ antiviral defenses were already turned on before the flu virus arrived, Foxman said.

The rhinovirus triggered production of the natural antiviral interferon in the cells. Interferon is part of the early immune system response to the invasion of pathogens, Foxman said.

The protective effect offered by this new interferon lasts for at least five days, she said.

The findings may allow researchers to better predict how respiratory viruses spread and find new ways to combat them in the absence of vaccines, the researchers said.

They emphasized, however, that whether the annual seasonal spread of the common cold virus will have a similar impact on COVID-19 remains unknown.

“Our results show that interactions between viruses can be an important driving force dictating how and when viruses spread through a population,” Foxman said.

“Since every virus is different, we still do not know how the common cold season will impact the spread of COVID-19, but we now know we should be looking out for these interactions.”

People who don’t believe in God may get better sleep, study says

Published

on

Atheists and agnostics are much more likely to sleep like an angel than Catholics and Baptists, a new study finds.

It included more than 1,500 participants in the Baylor University Religion Survey who were asked about their religious affiliation, behaviors and beliefs, as well as their average nightly sleep time and difficulty getting to sleep.

While 73% of atheists and agnostics said they got seven or more hours of nightly sleep, only 63% of Catholics and only 55% of Baptists said they got at least seven hours of sleep a night, preliminary data show.

Seven or more hours of sleep a night is recommended by the American Academy of Sleep Medicine, or AASM, for good health.

Catholics and Baptists were also more likely to report having difficulty falling asleep than atheists and agnostics.

Study participants who said they slept seven or more hours per night were much more likely to believe that they would get into heaven, compared to those who got less sleep.

However, beliefs about getting into heaven weren’t linked with difficulty falling asleep at night.

The researchers said that better sleep results in a more optimistic outlook and that in this study, that manifested as people believing they’d get into heaven.

“Mental health is increasingly discussed in church settings — as it should be — but sleep health is not discussed,” said study author Kyla Fergason, a student at Baylor University in Waco, Texas.

“Yet we know that sleep loss undercuts many human abilities that are considered to be core values of the church: being a positive member of a social community, expressing love and compassion rather than anger or judgment, and displaying integrity in moral reasoning and behavior,” Fergason said in AASM news release.

“Could getting better sleep help some people grow in their faith or become better Christians? We don’t know the answer to that question yet, but we do know that mental, physical and cognitive health are intertwined with sleep health in the general population,” she noted.

The findings were recently published in an online supplement of the journal Sleep, and were presented last week at the virtual annual meeting of the Associated Professional Sleep Societies.

Some COVID-19 survivors may have permanent nerve damage

Published

on

Placing a hospitalized COVID-19 patient in a face down position to ease breathing — or “proning” — has steadily gained traction as a pandemic lifesaver. But a small new study warns that it may lead to permanent nerve damage.

The concern is based on the experience of 83 COVID-19 patients who were placed face down while attached to a ventilator. Once they improved, all began post-COVID-19 rehabilitation at a single health care facility.

By that point, roughly 14% had developed a “peripheral nerve injury” (PNI) involving one or more major joints, such as the wrist, hand, foot or shoulder.

Despite that damage, study author Dr. Colin Franz said proning “is a lifesaving intervention, and we think it is saving lives during the COVID pandemic.”

And although placing patients face down has been known to cause skin pressure injuries in non-COVID-19 patients, he said nerve compression injuries are typically uncommon with regular repositioning and careful padding.

“So we were very surprised to find 12 out of 83 patients with nerve injuries,” said Franz, neurology director of the Regenerative Neurorehabilitation Laboratory at Northwestern University Feinberg School of Medicine, in Chicago.

He characterized the nature of the nerve damage as so severe that affected patients were “unlikely to fully recover.”

The damage included loss of hand function, frozen shoulder and foot dragging that may lead to a need for a brace, cane or wheelchair.
“Full recovery for nerve damage is estimated to occur in only about 10% of patients under the best of circumstances,” Franz explained. “And the recovery that does take place will happen over 12 to 24 months.”

In other words, the nerve damage might be the longest-lasting effect of COVID-19 for most of these patients, he suggested. And if the risk seen among the study group is any indication, thousands of patients worldwide could have the same damage, Franz said.

Franz noted that some, but not all, of the patients had pre-existing conditions such as diabetes that made them more likely to have nerve injuries from compression. Many of the patients were also old or obese.

But he and his colleagues suspect something about COVID-19 infection itself makes nerves more vulnerable to damage. Among the possible triggers: the increased inflammatory state brought on by SARS-CoV-2, the virus that causes COVID-19, as well as poor blood circulation and blood clotting.

Prone-triggered PNI may also result from “the way patients are positioned and the weight it may put on certain nerves for prolonged periods of time,” said Dr. Armeen Poor, an attending physician of pulmonary critical care medicine at Metropolitan Hospital Center in New York City, who reviewed the findings.

Another possible contributor: overworked hospital staff.

During the height of the pandemic, said Poor, “many hospitals were proning more patients at a time than usual. This excess strain on staff could have compromised the frequency of careful patient repositioning while prone, and potentially increased the risk of nerve injury.”

Dr. Nicholas Caputo, an associate chief and attending emergency physician at Lincoln Medical and Mental Health Center, Bronx, N.Y., also reviewed the findings. He said it’s important to recognize that this study focused only on patients proned while on a ventilator.

But, he noted, proning has been successfully deployed among non-ventilated patients, often in hopes of staving off ventilation. Such “self-proning” patients are awake and “instructed to change positions if they become uncomfortable.”

In the intensive care unit, however, ventilated patients are generally proned for eight to 12 hours before being turned, Caputo said. “This puts much more pressure on certain areas of the body, and places the patients at risk for complications such as peripheral neuropathies,” he added.

Hoping to reduce prone-linked PNI risk among intubated patients, Franz’s team has been “mapping” regions most vulnerable to nerve damage. That information could help doctors, nurses and physical therapists deploy modified positioning, extra padding and protection of vulnerable areas. Wearable sensors could be used to “measure and monitor [the] loading of nerves,” he said.

“In medicine we focus on ‘ABCs’ — airway, breathing and circulation — when there is an emergency,” Franz said. “Intubation and proning positioning fall within these categories and save lives. This is always the first priority. We do think these added measures will help prevent these nerve injuries, however.”

The findings have not yet been peer-reviewed but were reported online recently in medRxiv in advance of publication in The British Journal of Anaesthesia.
