COVID-19 was full of surprises early on, causing mild problems in the short term for some people and serious complications for others, according to the American Heart Association.
Long term, it may be just as capricious.
Studies are spotting potential heart and brain problems up to a year after infection with SARS-CoV-2, even in people who had mild COVID-19.
The possible long-term effects include “a myriad of symptoms affecting different organs,” said Dr. José Biller, director of the COVID-19 neurology clinic at Loyola Medicine in Maywood, Illinois. “So, it could be the lungs, it could be cardiovascular, it could be the nervous system, it could be mental health or behavioral problems.”
Estimates vary widely on how many people may be affected. Research suggests about 10% to 20% of people experience mid- or long-term issues from COVID-19, according to the World Health Organization.
The following was written as a summary of changes that consumers had made as a result of the Covid-19 conditions at the beginning of 2021. Here we are at the beginning of 2022. This provides a fascinating look back in time.
The global pandemic has changed all aspects of normal living, and ushered in an era where health and wellness are paramount decision drivers for the foreseeable future, especially when it comes to food and beverage choices. The 2021 Pollock Communications and Today’s Dietitian “What’s Trending in Nutrition” survey, with 1,165 registered dietitian nutritionists (RDNs) responding, provides an in-depth look at how dietitians believe consumers’ diets have changed due to COVID-19. The health revolution has exploded as a result of the pandemic, with the top findings for 2021 revealing a focus on foods that support immunity and provide comfort, as well as a major shift in snacking habits. Changes to the top 10 superfoods list also indicate a move toward foods that are plant-forward and support health, with green tea, a natural anti-inflammatory beverage, jumping from #10 last year to the #3 spot this year, and nutrient-rich spinach and leafy greens making their debut on the list. As consumers continue to search for diets that promote well-being and longevity, intermittent fasting surpasses the ketogenic diet as the #1 diet trend dietitians predict for 2021, and RDNs forecast consumers will be on the hunt for natural, clean labels and ingredients like cannabidiol (CBD), collagen and hemp. Here’s a look at the full results.
To paraphrase Claude Rains in the movie Casablanca, “I’m shocked, shocked to learn that … “
During the COVID-19 pandemic months of March 2020 to September 2020, U.S. alcohol retail store sales increased compared to usual trends while food services and drinking places sales decreased markedly during the same period, according to a new study at Columbia University Mailman School of Public Health. These results indicate an increase in home drinking in the U.S. The findings are published online in the journal Alcohol.
The researchers used alcohol retail store sales data of beer, wine, and liquor store (BWLS) purchases from January 1992 to September 2020 from the Monthly Retail Trade Survey, which provides sales estimates at retail and food services. Alcohol sales changes in the U.S. throughout the COVID-19 pandemic were used as an indicator of at-home drinking. Calculating variations in monthly sales enabled the authors to show annual differences in monthly BWLS sales between consecutive years from 1992 to 2020.
A new Cleveland Clinic-led study has identified mechanisms by which COVID-19 can lead to Alzheimer’s disease-like dementia. The findings, published in Alzheimer’s Research & Therapy, indicate an overlap between COVID-19 and brain changes common in Alzheimer’s, and may help inform risk management and therapeutic strategies for COVID-19-associated cognitive impairment.
Reports of neurological complications in COVID-19 patients and “long-hauler” patients whose symptoms persist after the infection clears are becoming more common, suggesting that SARS-CoV-2 (the virus that causes COVID-19) may have lasting effects on brain function. However, it is not yet well understood how the virus leads to neurological issues.
“While some studies suggest that SARS-CoV-2 infects brain cells directly, others found no evidence of the virus in the brain,” says Feixiong Cheng, Ph.D., assistant staff in Cleveland Clinic’s Genomic Medicine Institute and lead author on the study. “Identifying how COVID-19 and neurological problems are linked will be critical for developing effective preventive and therapeutic strategies to address the surge in neurocognitive impairments that we expect to see in the near future.”
In the study, the researchers harnessed artificial intelligence using existing datasets of patients with Alzheimer’s and COVID-19. They measured the proximity between SARS-CoV-2 host genes/proteins and those associated with several neurological diseases where closer proximity suggests related or shared disease pathways. The researchers also analyzed the genetic factors that enabled SARS-COV-2 to infect brain tissues and cells.
A year after the first U.S. coronavirus deaths, UCLA sociologist Patrick Heuveline reports on the dramatic impact
As a demographer — someone who studies how human populations grow and change — UCLA professor of sociology Patrick Heuveline typically spends time each year traveling around the world, talking to people about their hopes for their families and their dreams for the future.
“Demography is obviously all about numbers — but at its core, it’s about people’s lives,” he said.
A big part of understanding demographics is understanding mortality, which is why in 2020 Heuveline’s research took on a grim new reality. He began tracking worldwide COVID-19 deaths and interpreting what those numbers mean to overall life expectancy.
April marks a somber milestone in the pandemic: one year since the U.S. recorded its first COVID-19–related deaths. As of the end of March, more than 2.8 million around the world, including more than 550,000 Americans, have died of causes related to COVID-19.
In a worldwide study of 2,100 pregnant women, those who contracted COVID-19 during pregnancy were 20 times more likely to die than those who did not contract the virus, according to the University of Washington (UW).
UW Medicine and University of Oxford doctors led this first-of-its-kind study, published today in JAMA Pediatrics. The investigation involved more than 100 researchers and pregnant women from 43 maternity hospitals in 18 low-, middle- and high-income nations; 220 of the women received care in the United States, 40 at UW Medicine. The research was conducted between April and August of 2020.
The study is unique because each woman affected by COVID-19 was compared with two uninfected pregnant women who gave birth during the same span in the same hospital.
Aside from an increased risk of death, women and their newborns were also more likely to experience preterm birth, preeclampsia and admission to the ICU and/or intubation. Of the mothers who tested positive for the disease, 11.5% of their babies also tested positive, the study found.
Although antibodies induced by SARS-CoV-2 infection are largely protective, they do not completely protect against reinfection in young people, as evidenced through a longitudinal, prospective study of more than 3,000 young, healthy members of the US Marines Corps conducted by researchers at the Icahn School of Medicine at Mount Sinai and the Naval Medical Research Center, published April 15 in The Lancet Respiratory Medicine.
“Our findings indicate that reinfection by SARS-CoV-2 in health young adults is common” says Stuart Sealfon, MD, the Sara B. and Seth M. Glickenhaus Professor of Neurology at the Icahn School of Medicine at Mount Sinai and senior author of the paper. “Despite a prior COVID-19 infection, young people can catch the virus again and may still transmit it to others. This is an important point to know and remember as vaccine rollouts continue. Young people should get the vaccine whenever possible, since vaccination is necessary to boost immune responses, prevent reinfection, and reduce transmission.”
The study, conducted between May and November 2020, revealed that around 10 percent (19 out of 189) of participants who were previously infected with SARS-CoV-s (seropositive) became reinfected, compared with new infections in 50 percent (1.079 out of 2,247) of participants who had not been previously infected (seronegative). While seronegative study participants had a five times greater risk of infection than seropositive participants, the study showed that seropositive people are still at risk of reinfection.
New research found patients hospitalized with COVID-19 had a higher risk of stroke, compared with patients who had similar infectious conditions such as influenza and sepsis in prior studies. Those who had an ischemic stroke were more likely to be older, male, Black race, or have high blood pressure, Type 2 diabetes or an irregular heartbeat (atrial fibrillation) compared with other COVID-19 patients, according to late-breaking science presented today at the American Stroke Association’s International Stroke Conference 2021. The meeting was held virtually, March 17-19, 2021 and is a world premier meeting for researchers and clinicians dedicated to the science of stroke and brain health.
For this analysis, researchers accessed the American Heart Association’s COVID-19 Cardiovascular Disease Registry to investigate stroke risk among patients hospitalized for COVID-19, their demographic characteristics, medical histories and in-hospital survival. The COVID-19 Registry data pulled for this study included more than 20,000 patients hospitalized with COVID-19 across the U.S. between January and November 2020.
“These findings suggest that COVID-19 may increase the risk for stroke, though the exact mechanism for this is still unknown,” said lead study author Saate S. Shakil, M.D., a cardiology fellow at the University of Washington in Seattle. “As the pandemic continues, we are finding that coronavirus is not just a respiratory illness, but a vascular disease that can affect many organ systems.”
Two hundred eighty-one people (1.4%) in the COVID-19 CVD Registry had a stroke confirmed by diagnostic imaging during hospitalization. Of these, 148 patients (52.7%) experienced ischemic stroke; 7 patients (2.5%) had transient ischemic attack (TIA); and 127 patients (45.2%) experienced a bleeding stroke or unspecified type of stroke.
Researchers from Tel Aviv University (TAU) have proven that the coronavirus can be killed efficiently, quickly, and cheaply using ultraviolet (UV) light-emitting diodes (UV-LEDs). They believe that the UV-LED technology will soon be available for private and commercial use.
This is the first study conducted on the disinfection efficiency of UV-LED irradiation at different wavelengths or frequencies on a virus from the family of coronaviruses. The study was led by Professor Hadas Mamane, Head of the Environmental Engineering Program at TAU’s School of Mechnical Engineering, Iby and Aladar Fleischman Faculty of Engineering. The article was published in November 2020 issue of the Journal of Photochemistry and Photobiology B: Biology.
“The entire world is currently looking for effective solutions to disinfect the coronavirus,” said Professor Mamane. “The problem is that in order to disinfect a bus, train, sports hall, or plane by chemical spraying, you need physical manpower, and in order for the spraying to be effective, you have to give the chemical time to act on the surface. Disinfection systems based on LED bulbs, however, can be installed in the ventilation system and air conditioner, for example, and sterilize the air sucked in and then emitted into the room.
“We discovered that it is quite simple to kill the coronavirus using LED bulbs that radiate ultraviolet light,” she explained. “We killed the viruses using cheaper and more readily available LED bulbs, which consume little energy and do not contain mercury like regular bulbs. Our research has commercial and societal implications, given the possibility of using such LED bulbs in all areas of our lives, safely and quickly.”
More and more evidence is coming out that people with COVID-19 are suffering from cognitive effects, such as brain fog and fatigue.
And researchers are discovering why. The SARS-CoV-2 virus, like many viruses before it, is bad news for the brain. In a study published Dec.16 in Nature Neuroscience, researchers found that the spike protein, often depicted as the red arms of the virus, can cross the blood-brain barrier in mice.
This strongly suggests that SARS-CoV-2, the cause of COVID-19, can enter the brain.
The spike protein, often called the S1 protein, dictates which cells the virus can enter. Usually, the virus does the same thing as its binding protein, said lead author William A. Banks, a professor of medicine at the University of Washington School of Medicine and a Puget Sound Veterans Affairs Healthcare System physician and researcher. Banks said binding proteins like S1 usually by themselves cause damage as they detach from the virus and cause inflammation.
The COVID-19 pandemic is seriously affecting the sleep habits of half of those surveyed in a new study from The Royal and the University of Ottawa, leading to further stress and anxiety plus further dependence on sleep medication.
The global pandemic’s impact on daily routines extends to the bed, according to ‘Profiles of sleep changes during the COVID?19 pandemic: Demographic, behavioural and psychological factors’. The study was led by Principal Investigator Rébecca Robillard, an Assistant Professor and co-director of the Sleep Laboratory of the School of Psychology at the University of Ottawa, and Head Scientist in the Sleep Research Unit at The Royal Institute of Mental Health Research and published in the Journal of Sleep Research.
Dr. Robillard and her team, which was comprised of nearly two dozen scientists from across North America, conducted an online survey of 5,525 Canadian during the early phase of the COVID-19 pandemic. She walked us through some of the study’s most important findings.
As cases and hospitalizations from the pandemic begin to decline, collateral damage on the populace appears to be on the rise.
In just a few months, the COVID-19 pandemic swiftly and substantially worsened mental health among U.S. hourly service workers and their children – especially those experiencing multiple hardships, according to new research from the Center for Child and Family Policy at Duke University and Barnard College.
The study leverages real-time, daily survey data collected from Feb. 20, before the pandemic hit the U.S., to April 27, when it was well underway, to examine how the crisis affected parents’ and children’s mental well-being. The 645 survey respondents were parents of young children working in hourly service-industry positions in retail, food service or hotel industries in a large U.S. city.
A growing number of studies suggest many COVID-19 survivors experience some type of heart damage, even if they didn’t have underlying heart disease and weren’t sick enough to be hospitalized. This latest twist has health care experts worried about a potential increase in heart failure, according to a report in the American Heart Association News.
“Very early into the pandemic, it was clear that many patients who were hospitalized were showing evidence of cardiac injury,” said Dr. Gregg Fonarow, chief of the division of cardiology at the University of California, Los Angeles. “More recently, there is recognition that even some of those COVID-19 patients not hospitalized are experiencing cardiac injury. This raises concerns that there may be individuals who get through the initial infection, but are left with cardiovascular damage and complications.”
Fatty food may feel like a friend during these troubled times, but new research suggests that eating just one meal high in saturated fat can hinder our ability to concentrate — not great news for people whose diets have gone south while they’re working at home during the COVID-19 pandemic.
The study compared how 51 women performed on a test of their attention after they ate either a meal high in saturated fat or the same meal made with sunflower oil, which is high in unsaturated fat.
They worked in hospitals hundreds of miles from the epicenter of COVID-19. Their city of 24 million people locked down hard enough, and did enough testing, that it only had a few hundred cases of the disease.
But hundreds of young Chinese doctors in a new study still experienced a sharp drop in mood, a rise in depression and anxiety symptoms, and a doubling of their fear of workplace violence, in just the first month of the coronavirus pandemic.
Everyone experiences events in their own unique way. Take the COVID-19 pandemic – please. (With apologies to Henny Youngman). Turns out there is a negative bias to most peoples’ perceptions.
The survey examined the experiences of 4,149 adults living in the United States and how the crisis is impacting their mental health, physical health, romantic relationships, encounters of prejudice.
The Chapman University National COVID-19 and Mental Health Survey provides an in-depth look at the experiences of 4,149 adults living in the United States. The study asked questions about how the COVID-19 pandemic is impacting people’s mental health, physical health, romantic relationships and encounters of prejudice and discrimination.
What Are the Effects of COVID-19 on Mental Health and Behaviors?
Conducted at the end of April 2020, survey findings revealed that most people are staying home more than normal (89%), and the majority reported feeling more stressed (61%), nervous, anxious, or on edge (60%), and feeling down, depressed, or hopeless (45%) than normal due to the effects of the COVID-19 pandemic. People attributed the changes in their health behaviors to the pandemic, with about one-third reporting eating more because of stress (37%), eating more junk food (41%) and getting less exercise (35%).
