COVID-19-related heart, lung issues ease over time in survivors, study shows

Published

on

Long-term heart and lung damage can occur in COVID-19 patients, but it may ease with time, according to a new study.

A second study found that COVID-19 patients recover faster if they begin rehabilitation as soon as possible after getting off a respirator or leaving intensive care.

“The bad news is that people show lung impairment from COVID-19 weeks after discharge the good news is that the impairment tends to ameliorate over time, which suggests the lungs have a mechanism for repairing themselves,” said researcher Sabina Sahanic, a clinical Ph.D. student at University Clinic in Innsbruck, Austria.

“The findings from this study show the importance of implementing structured follow-up care for patients with severe COVID-19 infection. Importantly, CT unveiled lung damage in this patient group that was not identified by lung function tests,” she said.

Both studies were presented at a virtual meeting of the European Respiratory Society.

Sahanic’s research included 86 hospitalized COVID-19 patients in Austria who were enrolled between April 29 and June 9.

The patients, average age 61, were evaluated six, 12 and 24 weeks after leaving the hospital. At their first visit, more than half had at least one persistent symptom — mainly breathlessness and coughing. CT scans showed that 88% still had lung damage.

By their second visit at 12 weeks, patients’ symptoms had improved and 56% had signs of lung damage. Findings from the evaluations at 24 weeks weren’t available yet.

“Knowing how patients have been affected long-term by the coronavirus might enable symptoms and lung damage to be treated much earlier and might have a significant impact on further medical recommendations and advice,” Sahanic said in a meeting news release.

The other study included 19 patients with severe COVID-19. They spent an average of three weeks in intensive care and two weeks in a pulmonary ward before being transferred to a clinic for about three weeks of pulmonary rehabilitation.

A walking test evaluated their weekly progress. At the start of rehab, they could walk only an average of 16% of the distance they should manage to walk if healthy.

That average increased to 43% after three weeks of rehab. While a significant improvement, it’s still far below normal, the researchers noted.

“The most important finding was that patients who were admitted to pulmonary rehabilitation shortly after leaving intensive care progressed faster than those who spent a longer period in the pulmonary ward where they remained inactive,” said study author Yara Al Chikhanie. She’s a Ph.D. student at the Dieulefit Santé clinic for pulmonary rehabilitation and the Hp2 Lab at Grenoble Alps University in France.

“The sooner rehabilitation started and the longer it lasted, the faster and better was the improvement in patients’ walking and breathing capacities and muscle gain,” Al Chikhanie said in the release.

Patients who started rehabilitation in the week after coming off their ventilators progressed faster than those who were admitted after two weeks, she added. But how soon they can start rehab depends on when their doctors deem them medically stable.

“Despite the significant improvement, the average period of three weeks in rehabilitation wasn’t enough for them to recover completely,” Al Chikhanie said.

Data and conclusions presented at meetings are usually considered preliminary until peer-reviewed for publication in a medical journal.

Study: Restricting promotions of sweet foods cuts sugar, not profits

Published

on

Limiting marketing of high-sugar foods in supermarkets doesn’t cut into store profits, but it may improve public health, Australian researchers report.

Price promotions, end-of-aisle displays and putting products at eye level can stimulate sales. Ending these practices reduced purchase of sugar-sweetened drinks and candy in participating stores by the equivalent to nearly two tons of sugar, the researchers said. These included foods and drinks with added sugars, as well as natural sugar in honey, syrups and fruit juices.

The reductions in soft drink and candy purchases were particularly large, researchers said. Even so, profits were not affected, they added.

The study, published Oct. 7 in The Lancet Planetary Health, ran for 12 weeks and focused on 20 randomly selected stores in rural Australia. Some stores restricted promotion of sugary foods, others did not.

“Our novel study is the first to show that limiting [promotional] activities can also have an effect on sales, in particular, of unhealthy food and drinks,” said researcher Julie Brimblecombe, an associate professor of nutrition, dietetics and food at Monash University in Melbourne.

“This strategy has important health implications and is an opportunity to improve diets and reduce associated non-communicable diseases. It also offers a way for supermarkets to position themselves as responsible retailers, which could potentially strengthen customers’ loyalty without damaging business performance,” she said in a journal news release.

The changes affected sugar-sweetened drinks, candy and other sweets, table sugar and sweet biscuits or cookies. Among other things, these restricted price promotions, removed end-of-aisle and counter displays, and reduced refrigerator space for sugary drinks while placing large-size soft drinks elsewhere. Stores also promoted water and listed the amount of sugar in soft drinks.

As a result, added sugars purchased in foods and drinks fell 3%. Sugars in purchased sugar-sweetened drinks were cut by 7%, and from soda purchases it dropped 13%. Sugars from candy sales fell 7.5%, the researchers found.

Co-author Emma McMahon, a research fellow at Menzies School of Health Research in Casuarina, Australia, said researchers expected the strategy would work best on impulse items like sweet biscuits rather than on staples like table sugar.

“A different strategy for biscuits and items like table sugar should be explored to stimulate change in those buying behaviors,” she said in the release.

COVID-19 may have prolonged effect for pregnant women

Published

on

COVID-19 symptoms can last a long time in pregnant women, researchers say.

The new study included 594 pregnant women, with average age 31, across the United States who tested positive for the new coronavirus but were not hospitalized. Nearly one-third were health care workers.

On average, the women were about 24 weeks’ pregnant when they joined the study.

The most common early symptoms were cough, at 20%, sore throat, at 16%, body aches, at 12%, and fever, at 12%. By comparison, fever occurs in 43% of hospital patients who are not pregnant.

For 6%, loss of taste or smell was the first symptom. Other symptoms included shortness of breath, runny nose, sneezing, nausea, sore throat, vomiting, diarrhea or dizziness.

While six out of 10 women had no symptoms after four weeks, symptoms lasted eight or more weeks for 25%, the study found.

Thirty-seven days was the median time for symptoms to resolve, meaning half took longer, half took less time. The findings were published this month in the journal Obstetrics and Gynecology.

“COVID-19 symptoms during pregnancy can last a long time, and have a significant impact on health and well-being,” said senior author Dr. Vanessa Jacoby. She is vice chairwoman of research in the department of obstetrics, gynecology and reproductive sciences at the University of California, San Francisco.

Jacoby’s team also found that COVID-related symptoms were complicated by overlapping signs of normal pregnancy, including nausea, fatigue and congestion.

The majority of participants had mild disease and were not hospitalized, said first author Dr. Yalda Afshar, assistant professor in the division of maternal fetal medicine, department of obstetrics and gynecology at the University of California, Los Angeles.

Despite the potential risks of COVID-19 for pregnant women and their newborns, large gaps in knowledge about the disease’s course and prognosis remain, Afshar noted in a UCSF news release.

“Our results can help pregnant people and their clinicians better understand what to expect with COVID-19 infection,” Afshar said.

Pregnant women with COVID-19 don’t pass the virus to their newborns, study finds

Published

on

Oct. 12 (UPI) — New mothers infected with COVID-19 during pregnancy didn’t pass the virus to their babies, even if they breastfed and shared the same hospital room, according to a study published Monday by JAMA Pediatrics.

Mothers with severe COVID-19, however, delivered their babies, on average, one week earlier than healthy mothers, and their babies were four times as likely to need phototherapy to treat jaundice, the data showed.

“Between our findings and other studies, it is now known that there is a relatively low likelihood of vertical transmission from [COVID-19]-positive mothers to their newborns,” study co-author and pediatrician Melissa Stockwell told UPI.

“We also show that the risk remains low even with newborns rooming-in and direct breastfeeding practices, both of which had been concerns early in the pandemic,” said Stockwell, division chief of child and adolescent health at NewYork-Presbyterian/Columbia University Irving Medical Center.

Pregnant women may be at increased risk for severe illness from COVID-19, and reports have appeared that the risk for preterm delivery is higher among women infected with the virus, according to data released in June by the U.S. Centers for Disease Control and Prevention.

“There remains a concern for the effect of this virus on pregnant women,” study co-author Dr. Cynthia Gyamfi-Bannerman, a maternal-fetal medicine specialist at NewYork Presbyterian, told UPI.

However, no indication exists — at least to date — that their newborns are at any risk from the virus.

To explore the issue further, the Columbia University researchers tested 101 babies born to infected mothers in New York City between March 13 and April 24 — the height of the COVID-19 outbreak in the region.

Two of the babes had low levels of the virus in their nasal and throat samples initially, but neither developed symptoms, and they later tested negative, the researchers said.

The remainder all tested negative at birth and, and the 31 infants who were retested several days later remained negative. All 101 babies “roomed in” — or shared the same hospital rooms as their mothers — and bathing was delayed, the researchers said.

Some studies have recommended early bathing of babies born to mothers with COVID-19 as a way to reduce risk for virus spread, but early bathing has other health risks, including hypothermia, they said.

Three of the 10 babies born to mothers with severe COVID-19, however, required phototherapy, while six of 91 born to mothers with mild to moderate disease required the treatment, the data showed.

“Treating babies as babies seems safe during the COVID-19 pandemic,” study co-author Dr. Dani Dumitriu told UPI.

“This is particularly important given the continued spread of COVID-19 throughout the country and around the world,” said Dumitriu, a neonatologist at New York-Presbyterian.
