Covid-19 Prevention

Many People Could Still Be Infectious After 5-Day Quarantine: After a five-day quarantine, about a third of people infected with SARS-CoV-2 might still be infectious, according to new data. Internal Journal of Infectious Diseases

CDC Updates Mask Guidelines ― Cloth Masks Least Effective: The U.S. Centers for Disease Control and Prevention has updated its guidance on face masks, saying loosely woven cloth masks offer the least protection against COVID-19 and N95 and KN95 masks offer the most. The CDC update doesn't come out and say Americans should avoid cloth masks but clarifies that some kinds of masks work better than others.

How many times can I reuse my N95 mask?: The U.S. Centers of Disease Control and Prevention says health care workers wear an N95 mask up to five times. But experts say how often the average person can safely wear one will vary depending on how it's used. The amount of time a mask is worn is more important than how frequently it's worn, says Richard Flagan, who studies masks and aerosols at the California Institute of Technology. In general, he recommends limiting the use of an N95 mask to about two or three days.

Testing the effectiveness of KN95 and surgical mask 'fit hacks': Researchers have tested a variety of popular hacks for improving the fit of KN95 and surgical masks, and found that while some hacks do improve fit, they can also come at the cost of the wearer's comfort. PLoS ONE

Prior SARS-CoV-2 infection less protective against Omicron variant: Previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is about 90 percent effective for preventing reinfection with the alpha, beta, and delta variants but offers lower protection against reinfection with the Omicron variant, according to a letter to the editor published online Feb. 9 in the New England Journal of Medicine. New England Journal of Medicine

 

 COVID-19: Vaccines/Boosters

Fourth Vaccine Shot Less Effective Against Omicron, Israeli Study Says: A fourth shot of the COVID-19 vaccine boosts antibodies but doesn't provide enough protection to prevent infections from the Omicron variant, according to new research at an Israeli hospital. The preliminary results, challenge the idea of giving a second booster dose to slow the spread of the coronavirus, according to USA Today.

 

Placebo effect accounts for more than two-thirds of COVID-19 vaccine adverse events, researchers find: In a new meta-analysis of randomized, placebo-controlled COVID-19 vaccine trials, researchers at Beth Israel Deaconess Medical Center (BIDMC) compared the rates of adverse events reported by participants who received the vaccines to the rates of adverse events reported by those who received a placebo injection containing no vaccine. While the scientists found significantly more trial participants who received the vaccine reported adverse events, nearly a third of participants who received the placebo also reported at least one adverse event, with headache and fatigue being the most common. JAMA Network Open

 

Boosters 90% Effective at Preventing Omicron Hospitalizations: Booster shots of the Pfizer and Moderna COVID-19 vaccines appear to be highly effective at preventing hospitalizations due to the Omicron variant, according to three new CDC studies.

 

Pfizer and BioNTech Launch Trial of Omicron-Targeted COVID Vaccine: Both companies have started a clinical trial to test a new version of their vaccine specifically designed to target the COVID-19 Omicron variant, which has eluded some of the protection provided by the original two-dose vaccine regimen.

 

Omicron antibodies persist six months after Moderna vaccine boost but are six times lower: A booster dose of Moderna's COVID-19 vaccine showed signs of waning antibody levels against the omicron variant after six months, but the antibodies still remained effective against the variant in laboratory tests. New England Journal of Medicine

 

First study to show waning effectiveness of third dose of mRNA vaccines: A nationwide study from the U.S. Centers for Disease Control and Prevention (CDC) is the first to show that immunity against severe COVID-19 disease begins to wane four months after receipt of the third dose of an mRNA vaccine (Pfizer or Moderna). Waning immunity was observed during both the Delta and Omicron variant waves in similar fashion to how mRNA vaccine effectiveness wanes after a second dose. Although protection decreased with time, a third dose was still highly effective at preventing severe illness with COVID-19. Morbidity and Mortality Weekly Report

 

In reversal, FDA puts brakes on COVID shots for kids under 5: COVID-19 vaccinations for children under 5 hit another months long delay as U.S. regulators abruptly put the brakes on their efforts to speed review of the shots that Pfizer is testing for youngsters. The FDA said it had become clear the agency needed to wait for data on how well a third shot works for the youngest age group. Pfizer said in a statement that it expected the data by early April.

 

Had COVID? You're 5 times more prone to get it again if unvaccinated: Stay unvaccinated after a bout with COVID-19 and you're five times more likely than someone who has had the shot to get COVID again, the new study found. That's because the immunity acquired through an infection is short-lived. "It's very good for three months, and may well be good for a lot longer, but it's not permanent." New England Journal of Medicine

 

COVID-19 vaccination may protect against variants better than natural infection: Antibodies generated by COVID-19 vaccines are more suited to recognizing viral variants than antibodies that arise from natural infection, according to a study by researchers at Stanford Medicine. Cell

 

COVID-19: Treatment

Study supports use of remdesivir for COVID-19 patients on low-flow oxygen or no oxygen: Remdesivir, an antiviral drug used to treat COVID-19, increased the likelihood of clinical improvement in COVID-19 patients on low-flow oxygen or no oxygen, according to a new study.

FDA halts use of antibody drugs that don't work vs. omicron: COVID-19 antibody drugs from Regeneron and Eli Lilly should no longer be used because they don't work against the omicron variant that now accounts for nearly all U.S. infections. The Food and Drug Administration said it was revoking emergency authorization for both drugs, which were purchased by the federal government and have been administered to millions of Americans with COVID-19. If the drugs prove effective against future variants, the FDA said it could reauthorize their use.

 

Casirivimab + imdevimab prevents progression to symptomatic COVID-19: For asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR)-positive individuals living with an infected household contact, treatment with the subcutaneous casirivimab and imdevimab antibody combination reduces the incidence of symptomatic COVID-19 over 28 days, according to a study in Journal of the American Medical Association

 

Study strengthens case that vitamins cannot treat COVID-19: A new review of COVID-19 hospitalization data by researchers at The University of Toledo has found that taking immune-boosting supplements such as vitamin C, vitamin D and zinc do not lessen your chance of dying from COVID-19.

Ivermectin Does Not Stop Progression to Severe COVID: Randomized Trial: Ivermectin treatment given to high-risk patients with mild-to-moderate COVID-19 during the first week of illness did not prevent progression to severe disease, according to results from a randomized study.  "The study findings do not support the use of ivermectin for patients with COVID-19," researchers conclude in the paper published online today in JAMA Internal Medicine.

COVID-19: Long-Covid

Mild COVID cases still lead to attention and memory issues – study: People with mild COVID-19 who do not suffer any other traditional "long COVID" symptoms can still exhibit deteriorated attention and memory six to nine months after infection, a study by Britain's Oxford University has found. "What is surprising is that although our COVID-19 survivors did not feel any more symptomatic at the time of testing, they showed degraded attention and memory.” Reuters

 

COVID Brain Fog a 'True Neurologic Condition': Impaired cognition associated with COVID-19 appears to have a biological vs psychological basis, early research suggests. Investigators found abnormalities in cerebrospinal fluid (CSF) and other risk factors, including diabetes and hypertension present in individuals with mild COVID-19 experiencing persistent cognitive problems, often referred to as "brain fog." The study was published online January 18 in the Annals of Clinical and Translational Neurology.

 

Long COVID Associated With Risk of Metabolic Liver Disease: Post-acute COVID syndrome (PACS), an ongoing inflammatory state following infection with SARS-CoV-2, is associated with greater risk of metabolic-associated fatty liver disease (MAFLD), according to an analysis of patients at a single clinic in Canada published in Open Forum Infectious Diseases. Medscape

 

Most COVID ICU Survivors Show Adverse Effects 1 Year Later: Most patients with COVID-19 who were treated in an intensive care unit (ICU) show physical, mental, and cognitive effects a year later, new data found. Additionally, nearly 60% (57.8%) who were employed before ICU admission reported problems at work 1 year later, such as needing to work fewer hours or still taking sick leave. Two-thirds of study participants reported new physical problems as a result of ICU treatment for COVID.

Long COVID Linked to Unbalanced Gut Microbiome: People with a less diverse microbiome in their intestines were more likely to have lingering symptoms after coronavirus infection. The composition of the gut microbiome is “strongly” linked with long-COVID symptoms months a person recovers from their initial infection, a new study shows. Gut.

 

Scientists See Hope in New Therapy for COVID Brain Fog Patients: One of the most common symptoms of long COVID is brain fog: a life-altering condition characterized by slow thinking, confusion, difficulty remembering things, and poor concentration. A type of rehabilitation program that allows the brain to rewire itself has been successful in improving the lives of people with brain fog. The approaches are based on the concept of neuroplasticity: The ability of neural networks in the brain to change, adapt, and strengthen, much like a muscle in the body that has been trained and exercised. Though results of the cognitive studies have not been published, researcher says patients with brain fog have shown improvement after just 35 hours of therapy and are nearly 100% improved after 6 months.

Updated CPR Guidance Amidst Omicron Surge: The updated "2022 Interim Guidance to Health Care Professionals for Basic and Advanced Cardiac Life Support in Adults, Children, and Neonates With Suspected or Confirmed COVID-19," was published online January 24 in Circulation: Cardiovascular Quality and Outcomes.

COVID Fatigue Pervasive, but Men and Women React Differently: Most people experience COVID fatigue a few times a week, but men and women and older and younger people have reacted differently to it, a recent WebMD poll suggests. Just more than a third (34%) of men answered they have experienced fatigue, frustration, or feeling fed up daily compared with 40% of the women; 18% of male respondents said those feelings come a few times a week compared with 25% of women. Some (34% of men and 23% of women) said the feelings never come and they have adjusted well to the restrictions and changes. Poll results also highlight different experiences by age and indicate younger people have been more preoccupied with the effects. Medscape

20% of US Population Has Been Infected With COVID: Two years into the COVID-19 pandemic, at least 20% of the U.S. population has been infected with the virus, Johns Hopkins University's COVID Resource Center reports.

Stealth Omicron' spreads more than original strain: A sub-variant of the highly contagious Omicron coronavirus strain is even more infectious than the original version. Sub-variant BA.2—also called "stealth Omicron"—was detected earlier this year and has displaced the first Omicron variant, known as BA.1, as the dominant strain in Denmark. A person infected with BA.2 has a 39 percent chance of transmitting the virus to someone else in their household within a week, compared to a 29 percent risk with BA.1, Denmark's SSI health authority said in a statement.

About 73% of US Estimated to Be Immune to Omicron Variant: About 73% of Americans are now immune to the Omicron variant, which could increase to 80% by mid-March, a university health institute says. About half of eligible Americans have received booster shots, and about 80 million confirmed COVID-19 infections have been reported. Many more infections have occurred but haven't been officially recorded, The Associated Press reported.


PAIN

AAN Updates Treatment Guidance on Painful Diabetic Neuropathy: Updated guidelines from the American Academy of Neurology (AAN) advise against prescribing opioids for painful diabetic neuropathy but note that several other oral and topical therapies may help ease pain. The new guidance was published online December 27 in Neurology and has been endorsed by the American Association of Neuromuscular & Electrodiagnostic Medicine.

 

Opioids ease osteoarthritis pain only slightly. Deadly risks need to be weighed against benefit: In a new study, published today, a review of all the relevant research and found opioids only offer very small benefits for the relief of osteoarthritis pain.

Managing pain after knee, shoulder surgeries without opioids: Researchers created an approach to managing pain that eliminated opioids after common sports surgeries. In the first study, participants had undergone knee surgery to reconstruct their ACL. In the second study, participants had undergone surgery to repair their rotator cuff. All received a nerve block before surgery. In each study, one group of participants received a standard opioid regimen to manage pain. The other group took part in a pain management approach without opioids. The nonopioid regimen included pain relievers, nonsteroid anti-inflammatory drugs and muscle relaxants. Both studies found that the nonopioid regimen provided at least the same if not more pain control and patient satisfaction, compared with the standard opioid regimen. In both studies, the most common side effects were drowsiness, dizziness and gastrointestinal symptoms. In the rotator cuff study, participants who received the nonopioid regimen reported slightly lesser side effects than those who received the opioid regimen.

UBCO study finds psychedelic microdosing improves mental health: An international suggests repeated use of small doses of psychedelics such as psilocybin or LSD can be a valuable tool for those struggling with anxiety and depression.The study, recently published in Nature: Scientific Reports, demonstrated fewer symptoms of anxiety and depression, and greater feelings of wellbeing among individuals who reported consuming psychedelics in small quantities, or microdosing, compared to those who did not.

 

Study of LSD microdosing doesn't show a therapeutic effect: Proponents of LSD "microdosing"—taking small amounts of the drug at regular intervals—claim it can improve mood and cognitive function. But new research by the University of Chicago has not found evidence to support those claims. The study doesn't disprove microdosing's possible benefits, and that more investigation is needed. The study does show that taking small doses of LSD is safe. Addiction Biology

 

 Over the Counter (OTC) Cannabidiol Products Tied to Improved Pain, Sleep, Anxiety: Interim findings from the Advancing CBD Education and Science (ACES), a 100% virtual, open label, randomized controlled trial, show study participants experienced various degrees of "clinically meaningful" improvements in sleep quality, anxiety, and pain. “ACES is the largest clinical trial ever conducted on commercially available CBD products and provides first-of-its-kind real world evidence into what conditions users may experience benefit from CBD usage, whether these benefits are clinically meaningful, what attributes of CBD products may impact health outcomes, and what side effects may occur.” Medscape 

 

Flowered steering: How well do drivers fare after smoking cannabis? In a novel, two-year randomized trial, 191 regular cannabis users to took cannabis containing different levels of delta-9-tetrahydrocannabinol (THC), the psychoactive compound in cannabis or a placebo immediately before a series of driving simulation tests over several hours. Compared to participants who took the placebo, the THC group (who had smoked a cannabis cigarette with either 5.9 percent or 13.4 percent THC as they would "do at home to get high") displayed significantly diminished ability on a Composite Drive Score (CDS) that assessed key simulated driving variables, such as swerving in lane, responding to divided attention tasks and following a lead car. However, not all individuals displayed significantly diminished driving skills compared to the placebo group researchers said approximately 50 percent could be described as "impaired."

Concussion management is changing as more research suggests exercise is best approach: In the past few years, scientists have started to study aerobic exercise (or cardio training) as a management strategy for concussion symptoms. This exercise-is-medicine approach is diametrically opposed to the rest-is-best status quo. An academic review that summarizes the findings of individual studies shows that exercise is indeed one of the most effective, evidence-informed strategies for managing concussion symptoms. Beyond a brief period (24 to 48 hours) of rest after concussion, the science now suggests that exercise is more beneficial than rest.

No Amount of Alcohol Safe for the Heart: The widely held notion that consuming small to moderate amounts of alcohol is good for cardiovascular health is not supported by the data, the World Heart Federation (WHF) says in a new policy brief. In fact, the evidence is clear that any level of drinking can contribute to loss of a healthy life, the organization says. The WHF conclusions follow a recent report in the Lancet based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD), which found that there is no safe level of alcohol consumption.

Flavonoids may reduce mortality risk for people with Parkinson's disease: People with Parkinson's disease who eat more flavonoids—compounds found in richly colored foods like berries, cocoa and red wine—may have a lower mortality risk than those who don't, according to a new study.
