High-intensity exercise has no effect on mortality rate in older populations, study suggests

High-intensity exercise does not appear to add to risk of mortality among older adults, a new study has found.


The research, which was published in The BMJ medical journal on Wednesday, found that HIIT (high-intensity interval training) and MICT (moderate-intensity continuous training) for those aged 70-77 showed no increase in the risk of mortality compared to recommended daily activity.


”This study suggests that combined MICT and HIIT has no effect on all-cause mortality compared with recommended physical activity levels,” the study authors from the Norwegian University of Science and Technology in Norway, Newsgram reported.

Participants were splits into a control group, HIIT group and MICT group.

Participants were splits into a control group, HIIT group and MICT group.


The research followed a group of 1,567 men and women – 790 women and 777 men – in Norway over the course of five years.

The participants were put into a control group of 780 that followed Norwegian guidelines for physical activity, which state 30 minutes of moderate physical activity five times a week, MICT group of 387 and a HIIT group of 400. The HIIT group did two weekly high-intensity workout sessions, while the MICT did two moderate-intensity 50 minute workout sessions a week.

At the end of the five year study, the mortality rate for the combined HIIT and MICT group was 4.5%, nearly half the expected outcome of 10%, which is based on the 2% yearly mortality rate for people aged 70-75 according to Norway’s statistics. This supports the researchers expectations from “observational studies [that] have shown that older adults who are physically active have a higher health related quality of life than those who are less physically active,” the report read.

The mortality rate for the two groups compared to the control group, which was 4.7%, suggested no large difference in mortality rate among the exercise styles.


Though researchers noted before the study 87.5% of participants reported “overall good health,” thus suggesting a possible selection bias that could have influenced results.

Trump suggests he may hold weekend rallies in Florida, Pennsylvania after receiving green light from doctor

President Trump told Fox News’ Sean Hannity in an exclusive interview Thursday that his campaign is trying to make last-minute arrangements for holding weekend rallies in Florida and Pennsylvania after White House physician Dr. Sean Conley cleared him for public engagements earlier in the day.

“I think I’m going to try doing a rally on Saturday night if we have enough time to put it together,” Trump said on “Hannity”.


“We want to do a rally probably in Florida on Saturday night. I might come back and do one in Pennsylvania the following night,” he said, adding that “it’s incredible what’s going on. I feel so good.”

Dr. Conley sent out a memorandum Thursday evening stating that Trump will be able to return to public engagements this weekend, noting that Saturday will mark ten days since he was first diagnosed with the coronavirus.

Conely’s memo stated that Trump has responded “extremely well to treatment” and added there is no sign of “adverse therapeutic effects.”

The Centers for Disease Control and Prevention (CDC) says people “with mild to moderate COVID-19 remain infectious no longer than 10 days after symptom onset. People with more severe symptoms can remain infectious for longer.”


Trump said he will “probably” take a test on Friday to be sure of a negative result, but claimed his doctors “found very little infection or virus, if any,” in a previous unspecified test.

“I don’t know if they found any,” he said. “I didn’t go into it greatly with the doctors. We have these great doctors at Walter Reed, and you do rely on them, they are really fantastic talents and they came in from Johns Hopkins also and other places.


Trump said he was being closely monitored, telling Hannity that he “never saw so many doctors looking over me.

“I think I’m the most analyzed human being in the world right now,” he said.

Having a baby later in life may increase longevity, study suggests

Women who have kids later on in life may live longer, according to the findings of a recent study.

Following the birth of a woman’s last child, certain measurements may be linked with her projected lifespan, according to a study published Wednesday in Menopause, the journal of The North American Menopause Society (NAMS).

More specifically, leukocyte telomere length – telomeres “are repeating DNA-protein complexes that protect the ends of chromosomes and have proven to be critical for maintaining genomic stability,” per a news release on the findings – may play a role in a woman’s longevity. A woman’s age at the birth of her last child may affect telomere length, ultimately impacting long-term health, the researchers said.

Longer telomeres are thought to be beneficial for long-term health, while shorter ones can signify “various chronic conditions such as cardiovascular disease, type 2 diabetes, some neurologic conditions, and various cancers,” past studies have suggested, according to the news release.


At least one previous study has suggested that a woman’s age at the birth of her last child affected telomere length, said researchers. The study published Wednesday was larger, including more than 1,200 perimenopausal and postmenopausal women of “various ethnicities and backgrounds.”

“In addition, unlike previous studies, this study took into consideration sociodemographic factors related to childbearing patterns and health decisions,” per the release.

The researchers who conducted the new study found that a woman’s age at the birth of her final child “is positively associated with telomere length, meaning that women who delivered their last child later in life were likely to have longer telomeres, a biomarker of long-term health and longevity.”


However, “more research is needed to determine whether older maternal age at last birth causes telomeres to lengthen or whether telomere length serves as a proxy for general health and corresponds with a woman’s ability to have a child at a later age,” said Dr. Stephanie Faubion, NAMS medical director, in a statement.

The findings were also limited to women who had one or two live births or those who had used birth control orally, they said.

The coronavirus can survive on skin for this many hours, study suggests

New research out of Japan suggests the novel coronavirus can live on human skin for up to nine hours.

In a study published in the journal Clinical Infectious Diseases on Oct. 3, researchers from the Kyoto Prefectural University of Medicine found that SARS-CoV-2 outlived the influenza A virus (IAV) on human skin, which remained viable for about two hours.

New research out of Japan suggests the novel coronavirus can live on human skin for nine hours.

New research out of Japan suggests the novel coronavirus can live on human skin for nine hours.

The researchers “generated a model that allows the safe reproduction of clinical studies on the application of pathogens to human skin and elucidated the stability of SARS-CoV-2 on the human skin,” they wrote. The models were created from samples of human skin taken from autopsies, per Live Science.


Using the model, the researchers found the survival of SARS-Cov-2 was “significantly longer” compared to IAV, with 9.04 hours and 1.82 hours, respectively.

When both viruses were subsequently mixed with mucus to imitate a cough or sneeze, the novel coronavirus lasted about 11 hours, the researchers found.


Thankfully, however, both SARS-CoV-2 and the influenza A virus were “completely inactivated within 15 [seconds] by ethanol treatment,” or hand sanitizer containing 80% ethanol, they said.

“The 9-[hour] survival of SARS-CoV-2 on human skin may increase the risk of contact transmission in comparison with IAV, thus accelerating the pandemic. Proper hand hygiene is important to prevent the spread of SARS-CoV-2 infection,” they concluded.


The study had at least one limitation, however. The researchers in their review did not consider the viral load needed to cause a COVID-19 infection from contact with contaminated skin, Live Science noted.

The research comes after a separate study conducted early on in the pandemic, in March, found that the novel virus can live on surfaces such as plastic and stainless steel for up to three days.


That research, published in the medRxiv depository, noted that the virus can remain on copper surfaces for four hours and carboard for up to 24 hours. The research also found it could stay on stainless steel and plastic for anywhere between two and three days.

Another study suggests common cold protects some from COVID-19

The common cold can make you miserable, but it might also help protect you against COVID-19, a new study suggests.

The researchers added that people who’ve had COVID-19 may be immune to it for a long time, possibly even the rest of their lives.

The research focused on memory B cells, long-lasting immune cells that detect pathogens, produce antibodies to destroy them, and remember them for the future.

The study authors compared blood samples from 26 people who were recovering from mild to moderate COVID-19 and 21 healthy people whose samples were collected six to 10 years ago, long before they could have been exposed to COVID-19.

They found that B cells that attacked previous cold-causing coronaviruses appeared to also recognize the coronavirus that causes COVID-19.

This could mean that anyone who’s ever been infected by a common cold coronavirus — nearly everyone — may have some amount of immunity to COVID-19, according to infectious disease experts at the University of Rochester Medical Center in Rochester, N.Y.

The researchers also found that COVID-19 triggers memory B cells, which means those immune cells are ready to fight the coronavirus the next time it shows up in the body.

“When we looked at blood samples from people who were recovering from COVID-19, it looked like many of them had a preexisting pool of memory B cells that could recognize [the coronavirus] and rapidly produce antibodies that could attack it,” study author Mark Sangster said in a university news release. He’s a research professor of microbiology and immunology.

Because memory B cells can survive for decades, they could protect COVID-19 survivors from subsequent infections for a long time, but further research is needed to confirm that, according to the authors.

“Now we need to see if having this pool of preexisting memory B cells correlates with milder symptoms and shorter disease course — or if it helps boost the effectiveness of COVID-19 vaccines,” study co-author David Topham, professor of microbiology and immunology, said in the release.

The study was published in the September/October issue of the journal mBio.

Dozens of animal species worldwide may be susceptible to the coronavirus, research suggests.

The previously unknown infection is thought to have started in bats, before “jumping” into humans, possibly via pangolins.

Concerns were raised early in the outbreak when a dog in Hong Kong tested “weak positive” for the coronavirus, however, experts stressed there was “no evidence pet animals can be a source of infection”.

A tiger in a New York zoo also hit the headlines when it caught the virus, even developing a tell-tale dry cough.

When it comes to animals catching the coronavirus, experts have previously warned against “mass hysteria”. Scientists from University College London (UCL) have since reported, however, 26 creatures that are “regularly in contact with people” may be susceptible to the infection.

The coronavirus enters cells when its so-called spike protein interacts with a receptor called ACE2.

Based on existing evidence, the UCL team believe it is unlikely the virus could infect a species without binding to ACE2.

The scientists therefore investigated ACE2 mutations across 215 animals. These mutations mean the receptor differs from the human version, “reducing the stability of the binding complex” between the virus’ spike protein and the host’s receptor.

Results, published in the journal Scientific Reports, suggest that in animals like sheep and great apes – chimpanzees, gorillas, orangutans and bonobos – the virus’ spike protein and the species’ ACE2 receptor “would be able to bind together just as strongly as they do when the virus infects people”.

The scientists stressed, however, that for some species this is just a hypothesis. Sheep, for example, have not been studied for infection risk specifically, just spike protein and ACE2 binding.

“We wanted to look beyond just the animals that had been studied experimentally, to see which animals might be at risk of infection, and would warrant further investigation and possible monitoring,” said lead author Professor Christine Orengo.

“The animals we identified may be at risk of outbreaks that could threaten endangered species or harm the livelihoods of farmers.

“The animals might also act as reservoirs of the virus, with the potential to re-infect humans later on, as has been documented on mink farms.”

These minks are thought to have been infected by farm workers. In a few cases, the minks have transmitted the virus to other people, in the first reported cases of animal-to-human transmission.

When looking at the risk among different types of animals, the scientists predicted most birds, fish and reptiles do not appear capable of catching the coronavirus.

US Futures Rise As President Trump’s Medical Team Suggests Monday Return To White House

U.S. futures spiked on Sunday night as of President Donald Trump’s healthcare providers expressed optimism over his timely return to the White House.

What Happened: Dr. Brian Garibaldi, a member of Trump’s medical team, said the President could be discharged from the Walter Reed Medical Center, where he is undergoing treatment for COVID-19, as early as Monday, and be back in the White House, CNN reported.

Garibaldi’s comments came amid uncertainty over Trump’s health, with contradicting reports. The president’s physicians had revealed earlier in the day that he was being treated with dexamethasone, a powerful steroid reserved for extreme COVID-19 cases, CNBC reported.

Dr. Vin Gupta, a faculty member at the University of Washington’s Institute for Health Metrics and Evaluation, told CNBC that the disclosure indicates the president may be suffering from pneumonia.

Trump’s physician Dr. Sean Conley said that Trump had suffered two episodes of transient drops in his oxygen saturation, according to CNN.

“It was a determination of the team based on the timeline from the initial diagnosis that we initiate dexamethasone,” said Conley.

The president left the hospital briefly on Sunday — to be driven around in an SUV in order to greet his supporters, CBS News reported.

Why It Matters: Dr. Nahid Bhadelia, an infectious disease specialist at the Boston University School of Medicine, told CNBC that she would not discharge someone who was just put on steroids.

Conflicting accounts of the president’s treatment have emerged since Saturday as his doctors remain evasive on key health parameters including on whether he required supplemental oxygen.

Meanwhile, several members of the president’s inner circle at the Republican party have tested positive for COVID-19, including three senators.

Price Action: S&P 500 futures rose 0.77% to 3,365, while Dow Jones Industrial Average Futures gained 0.78% to 22,779. Nasdaq futures traded 1.06% higher at 11,352.50 at press time.

Trump suggests he may quarantine after top aide Hope Hicks tests positive for coronavirus

Hope Hicks, one of President Donald Trump’s closest aides, has tested positive for the coronavirus, and the president suggested he may quarantine.

After NBC News and other outlets reported on Hicks’ positive test, Trump himself confirmed it Thursday night in an interview with Fox News’ Sean Hannity. He also said that he had just been tested and was awaiting results either Thursday night or Friday. 

“She did test positive. She is a hard worker, a lot of masks, she wears masks a lot. She tested positive. I just went out with the test, we will see,” Trump said. “We spend a lot of time, the first lady just went and got a test also. Whether we quarantine, whether we have, we don’t know.”

Hicks, who has been known to spend a lot of time with Trump, had traveled with the president to the debate Tuesday night in Cleveland. She was seen not wearing a mask.

Trump, 74, himself rarely wears a mask and has mocked his Democratic rival, Joe Biden, 77, for often wearing face coverings. 

The Trump campaign referred questions to the White House. The White House didn’t comment on reports that Hicks had tested positive, but a spokesman issued a statement about the administration’s Covid-19 protocols. 

“The President takes the health and safety of himself and everyone who works in support of him and the American people very seriously,” Judd Deere, the spokesman, said in a statement. “White House Operations collaborates with the Physician to the President and the White House Military Office to ensure all plans and procedures incorporate current CDC guidance and best practices for limiting COVID-19 exposure to the greatest extent possible both on complex and when the President is traveling.”

Hicks’ positive test was first reported by Bloomberg News, which cited people familiar with the matter. The Associated Press also reported it, citing an official. Bloomberg also reported that Hicks had traveled with Trump to a rally Wednesday night in Minnesota.

The New York Times reported that the White House knew about Hicks’ condition Wednesday night, and that she is under quarantine.

The latest revelation comes as coronavirus cases reach nearly 7.23 million in the United States, according to a Johns Hopkins University tally. Worldwide, the virus has infected about 34 million and killed more than 1 million. At least 206,971 have died in the U.S.

Hicks, 31, is among the highest-ranking people in Trump’s orbit to have reportedly tested positive for the coronavirus.

In July, Trump’s national security advisor, Robert O’Brien, tested positive for the coronavirus. At the time, the White House said that O’Brien was experiencing “mild symptoms” and was “self-isolating and working from a secure location off-site.”

“There is no risk of exposure to the President or the Vice President. The work of the National Security Council continues uninterrupted,” the White House said in a July statement.

Other administration officials have previously been diagnosed with the coronavirus.

In May, Vice President Mike Pence’s press secretary, Katie Miller, tested positive for Covid-19,
