Indirect adverse effects of COVID-19 on children and youth’s mental, physical health

Despite reports that children and young people may be less likely to get coronavirus disease 2019 (COVID-19) than older adults, there may be substantial indirect adverse effects of the disease on their physical and mental health, according to an analysis in CMAJ (Canadian Medical Association Journal).

“While children and young people seem rarely to be victims of severe COVID-19, we should anticipate that they will experience substantial indirect physical, social and mental health effects related to reduced access to health care and general pandemic control measures,” says Dr. Neil Chanchlani, University of Exeter, United Kingdom.

The authors describe a range of potential adverse effects and contributing factors as well as mitigation strategies for health care providers and health systems.

Adverse effects include:

One in four UK adults at risk of hunger and potential malnutrition following lockdown

We all know the expression – a gift that keeps on giving. Well, it appears the coronavirus is the opposite of that – an affliction that keeps on taking.

One in four adults in the UK are experiencing food insecurity, which is likely to have left them susceptible to hunger and potential malnutrition, during the COVID-19 pandemic. That is the main finding of a survey published today by Feeding Britain and Northumbria University’s Healthy Living Lab.

The survey finds that 25% of adults have struggled during the pandemic to access food they can afford, and are likely to have been susceptible to hunger and potential malnutrition as a result. Meanwhile, nearly one in four adults looking after children have eaten less so they can feed the children in their household.

Study in Chinese Doctors Shows Mental Toll of COVID-19 Caring

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.

The new findings, published in JAMA Network Open by an American and Chinese team, show in stark terms the potential mental toll of being a frontline healthcare worker in the time of COVID-19.

The rise in symptoms among 385 first year medical residents in Shanghai contrasts with data from members of the previous year’s crop of residents who took part in the same study from 2018 to 2019.

Smokers may have more receptors for the new coronavirus

As if smoking weren’t bad enough for you, it seems the new coronavirus likes it, too. The lungs of people who smoke may contain more of the receptors that the new coronavirus uses to invade cells. This could explain why people with the virus who also smoke appear to be particularly vulnerable to severe illness.

The majority of people who acquire SARS-CoV-2, the virus that causes COVID-19, experience mild-to-moderate symptoms and will fully recover without hospital treatment.

However, several studies suggest that people who smoke are significantly more likely than people who do not to develop a severe form of the illness.

For example, according to a recent study of COVID-19 cases in hospitals in mainland China, 11.8% of people who smoked had a nonsevere form of the disease, while 16.9% had severe disease.

To break into cells and start replicating itself, the virus latches onto a protein receptor called angiotensin-converting enzyme 2 (ACE2), which is present in the cells’ membranes.

Smoking Nearly Doubles Rate of COVID-19 Progress

As if smoking per se weren’t bad enough, now, it turns out that smoking significantly worsens COVID-19, according to a new analysis by UC San Francisco of the association between smoking and progression of the infectious disease.

In a meta-analysis of studies that included 11,590 COVID patients, researchers found that among people with the virus, the risk of disease progression in those who currently smoke or previously smoked was nearly double that of non-smokers. They also found that when the disease worsens, current or former smokers had more acute or critical conditions or death. Overall, smoking was associated with almost a doubling of the risk of disease progressing.

Heart attacks, heart failure, stroke: COVID-19’s dangerous cardiovascular complications

Like the gift that keeps on giving, COVID-19 is the plague that keeps on taking. It turns out that the affliction can cause complications with other medical conditions.

COVID-19 can cause serious cardiovascular complications including heart failure, heart attacks and blood clots that can lead to strokes, emergency medicine doctors report in a new scientific paper. They also caution that COVID-19 treatments can interact with medicines used to manage patients’ existing cardiovascular conditions.

The new paper from UVA Health’s William Brady, MD, and colleagues aims to serve as a guide for emergency-medicine doctors treating patients who may have or are known to have COVID-19. The authors note that much attention has been paid to the pulmonary (breathing) complications of COVID-19, but less has been said about the cardiovascular complications that can lead to death or lasting impairment.

How good are face shields? – JAMA

There are a plethora of masks around, homemade as well as store bought. The range of effectiveness is vast. The Journal of the American Medical Association (JAMA) suggests that face shields may be a worthwhile alternative.

4506_face_shield.jpg

Face shields come in various forms, but all provide a clear plastic barrier that covers the face. For optimal protection, the shield should extend below the chin anteriorly, to the ears laterally, and there should be no exposed gap between the forehead and the shield’s headpiece. Face shields require no special materials for fabrication and production lines can be repurposed fairly rapidly. Numerous companies, including Apple, Nike, GM, and John Deere, have all started producing face shields. These shields can be made from materials found in craft or office supply stores. Thus, availability of face shields is currently greater than that of medical masks.

Heating could be best way to disinfect N95 masks for reuse

Since the outbreak of the COVID-19 pandemic, N95 face masks have been in short supply. Health care workers, in particular, desperately need these masks to protect themselves from the respiratory droplets of infected patients. But because of the shortage, many have to wear the same mask repeatedly. Now, researchers reporting in ACS Nano, the American Chemical Society publication have tested several methods for disinfecting N95 materials, finding that heating them preserves their filtration efficiency for 50 cycles of disinfection.

N95 masks contain a layer of “meltblown” polypropylene fibers that form a porous, breathable network. To help capture smaller particles that could slip through the holes, the fibers are electrostatically charged. The U.S. Centers for Disease Control and Prevention has recommended several methods for disinfecting N95 masks, such as heating, ultraviolet (UV) radiation and bleach treatment, but so far they have not been tested extensively, especially for multiple rounds of disinfection. Yi Cui and colleagues wanted to compare five of the methods that could reasonably be used within a hospital setting to see how mask materials hold up to repeated disinfections. Continue reading

Calming your mind – Mayo Clinic

The coronavirus attacks us on a number of fronts, respiratory system big time. But, living in the shadow of the virus takes a toll on all of us whether we succumb to the disease or not. It has changed our daily lives in many stressful ways. The following is from Dr. Amit Sood , former internal medicine physician at Mayo Clinic. He was director of research in the Complementary and Integrative Medicine Program at Mayo Clinic in Rochester, Minnesota, and was chair of the Mind-Body Medicine Initiative at Mayo Clinic.

Imagine it is spring 2025

Tucked in your blanket, trying to sleep at night, your mind travels back five years.

You remember the fear — fearing doorknobs, grocery bags, light switches, sneezes, handshakes and hugs.

You remember the sadness — the loss of freedom, time with colleagues, birthday parties, sleepovers, visits to the mall.

You remember the anger — anger at human greed, irrationality, willful ignorance.

You remember the grief — sobbing at the loss of fellow beings who breathed their last breath alone in an ICU to the sound of a ventilator.

But it’s not all negative.

Best material for homemade face masks may be combination of two fabrics

If, like me, you have had a problem finding a good face mask for the pandemic times, this info  may solve your problem.

Researchers from the American Chemical Society report that a combination of cotton with natural silk or chiffon can effectively filter out aerosol particles — if the fit is good.

In the wake of the COVID-19 pandemic, the U.S. Centers for Disease Control and Prevention recommends that people wear masks in public. Because N95 and surgical masks are scarce and should be reserved for health care workers, many people are making their own coverings. Now, researchers report in ACS Nano that a combination of cotton with natural silk or chiffon can effectively filter out aerosol particles — if the fit is good. Continue reading

Will social distancing be the new normal? Mayo Clinic

As some states look toward relaxing restrictions and social distancing measures, such as stay-at-home orders, new projections suggest social distancing may need to continue through 2022. Researchers predict that SARS-CoV-2, the virus that causes COVID-19, will return every winter, and that prolonged or intermittent social distancing strategies could limit the strain on health care systems.

Summary of preliminary data about obesity and severity of COVID-19

It may be that Eat less; move more; live longer which I have been writing about for nearly 10 years here, also has some relevance in the fight against COVID-19 .

In a Nature Reviews Endocrinology “Comment” authors from the German Center for Diabetes Research (DZD), the Boston Children’s Hospital and the Harvard T.H. Chan School of Public Health call for more research about the relationships of obesity, disproportionate fat distribution and impaired metabolic health with the severity of COVID-19.

The authors raise the point that most of the studies that have reported comorbidities in patients with COVID-19 did not provide data on body weight and height, which are used to estimate adipose tissue mass, by calculating the BMI. In their Comment they also briefly summarize novel research findings, deriving in part from articles which have not yet undergone peer-review, indicating that overweight and, particularly, obesity may associate with a substantial risk of a severe course of COVID-19. Importantly, these studies suggest that this risk is independent of cardiometabolic diseases and other comorbidities.

The authors then discuss possible mechanisms explaining this relationship. Among them respiratory dysfunction in obesity may result in hypoventilation-associated pneumonia and hypoxia-induced cardiac stress. Furthermore, they highlight that not only the calculation of the BMI, but also the measurement of the waist circumference and of glucose and insulin levels, which can be used to determine the presence of prediabetes and insulin resistance, may be important, as these parameters are independent determinants of cardiometabolic diseases, pneumonia and mortality.

The peer-reviewed study, published as a preprint, will help focus efforts to understand what SARS-COV-2 does in the body, why some people are more susceptible, and how best to search for treatments, the researchers say.

Multiple research models

When news broke about a new coronavirus in China, Ordovas-Montanes and Shalek had already been studying different cell types from throughout the human respiratory system and intestine. They also had gathered data from primates and mice.

Boost your immune system with these tips – AHA

I have spent the bulk of the past 10 years on this blog exhorting you to eat less; move more; live longer. Now, it seems that in the light of the global pandemic, they are still key.

For years, Dr. Ahmad Garrett-Price has been counseling patients about the need to keep their immune systems strong, emphasizing exercise, nutrition and sleep.

As the COVID-19 pandemic toll continues to grow, the advice is even more relevant.

“We don’t have a proven vaccine, and we don’t have proven treatments,” said Garrett-Price, a family practice physician with Baylor Scott & White Health System in Dallas. “So, our immune system is our first line of defense.”

Although a strong immune system is helpful, he and other health experts stress the guidelines in place to battle the coronavirus’s spread remain crucial: social distancing, frequent hand-washing, avoiding touching your face with unwashed hands, and staying at home as much as possible to avoid getting COVID-19 in the first place.
