Physio-metabolic and clinical consequences of wearing face masks—Systematic review with meta-analysis and comprehensive evaluation

Kai Kisielinski et al

Background: As face masks became mandatory in most countries during the COVID-19 pandemic, adverse effects require substantiated investigation.

Methods: A systematic review of 2,168 studies on adverse medical mask effects yielded 54 publications for synthesis and 37 studies for meta-analysis (on n = 8,641, m = 2,482, f = 6,159, age = 34.8 ± 12.5). The median trial duration was only 18 min (IQR = 50) for our comprehensive evaluation of mask induced physio-metabolic and clinical outcomes.

Results: We found significant effects in both medical surgical and N95 masks, with a greater impact of the second. These effects included decreased SpO2 (overall Standard Mean Difference, SMD = −0.24, 95% CI = −0.38 to −0.11, p < 0.001) and minute ventilation (SMD = −0.72, 95% CI = −0.99 to −0.46, p < 0.001), simultaneous increased in blood-CO2 (SMD = +0.64, 95% CI = 0.31–0.96, p < 0.001), heart rate (N95: SMD = +0.22, 95% CI = 0.03–0.41, p = 0.02), systolic blood pressure (surgical: SMD = +0.21, 95% CI = 0.03–0.39, p = 0.02), skin temperature (overall SMD = +0.80 95% CI = 0.23–1.38, p = 0.006) and humidity (SMD +2.24, 95% CI = 1.32–3.17, p < 0.001). Effects on exertion (overall SMD = +0.9, surgical = +0.63, N95 = +1.19), discomfort (SMD = +1.16), dyspnoea (SMD = +1.46), heat (SMD = +0.70), and humidity (SMD = +0.9) were significant in n = 373 with a robust relationship to mask wearing (p < 0.006 to p < 0.001). Pooled symptom prevalence (n = 8,128) was significant for: headache (62%, p < 0.001), acne (38%, p < 0.001), skin irritation (36%, p < 0.001), dyspnoea (33%, p < 0.001), heat (26%, p < 0.001), itching (26%, p < 0.001), voice disorder (23%, p < 0.03), and dizziness (5%, p = 0.01).

Discussion: Masks interfered with O2-uptake and CO2-release and compromised respiratory compensation. Though evaluated wearing durations are shorter than daily/prolonged use, outcomes independently validate mask-induced exhaustion-syndrome (MIES) and down-stream physio-metabolic disfunctions. MIES can have long-term clinical consequences, especially for vulnerable groups. So far, several mask related symptoms may have been misinterpreted as long COVID-19 symptoms. In any case, the possible MIES contrasts with the WHO definition of health.

Conclusion: Face mask side-effects must be assessed (risk-benefit) against the available evidence of their effectiveness against viral transmissions. In the absence of strong empirical evidence of effectiveness, mask wearing should not be mandated let alone enforced by law.

COVID-19 May Have Troubling Impacts—May Shrink Numerous Parts of the Brain

What are the prolonged neurological clinical consequences related to brain changes in persons with mild COVID-19 infection, if any? Researchers from India sought to answer this and other questions via a systemic review of investigations targeting COVID-19 and the human brain. What is the possible connection of COVID-19 and direct brain injury via encephalopathy (a disease of the brain that alters brain function or structure), for example?

In this review, the investigators, including corresponding author Puranam Revanth Kumar, Ph.D., affiliated with IFHE University, Hyderabad, found that when compared to a control group, study subjects who tested positive for COVID-19 presented more brain shrinkage, grey matter shrinkage and tissue damage. This damage primarily afflicts segments of the human brain linked to odor, ambiguity, strokes, reduced attention, headaches, sensor abnormalities, depression and mental abilities for a few months post the first infection.

Published in the Journal of Neuroscience & Biobehavioral Reviews, TrialSite provides a breakdown of this study result---outcomes which didn’t find much media attention in North America.

While SARS-CoV-2, the virus behind COVID-19, leads to respiratory disease, the novel coronavirus infection can also have negative impacts on the brain. This means that the disease symptoms are not just limited to respiratory systems but rather can impact other organs in the human body.

Viruses, in general, can affect neurological systems. With COVID-19, numerous studies point to significant incidences of neurological and cognitive abnormalities in the infected. Citing studies such as Raahimi et al., 2021, the current authors point to evidence that COVID-19 can impact the brain directly.

Does COVID-19 invade the human brain?

In this study, the authors from India point to evidence that SARS-CoV-2 is able to penetrate the brain. Here the systematic review of existing studies reveals that even mild COVID-19 infection can shrink the brain by up to 2%. The team reported that based on their evaluation of existing studies (some using various scans), patients with COVID-19, even a mild version, can lose up to 0.2% to 2% of their olfactory cortex (part of the brain that helps with smell).

Summary of review

The latest study published in the peer-reviewed journal Neuroscience and Biobehavioral Reviews, authored by Puranam Revanth Kumar, B Shilpa, and Rajesh Kumar Jha, reports that continued neurological clinical consequences related to brain changes can occur in individuals with mild forms of COVID-19. When compared to a control group, people identified as positive had more brain and grey matter shrinkage and tissue damage.

The team based in the southern India city of Hyderabad reported, “The damage occurs predominantly in areas of the brain that are associated with odor, ambiguity, strokes, reduced attention, headaches, sensory abnormalities, depression, and mental abilities for a few months after the first infection.”

Even a mild COVID-19 infection shows the potential to shrink an individual’s brain. And the symptoms are offering lots of supporting data points---after all, the viral infection can trigger all sorts of mental/behavioral health and neurologically related conditions from brain fog to loss of smell. The researchers point to numerous autopsy studies supporting the premise.

Canadian Nurse Sues Health System for Dismissal Over Covid Concerns

The Covid pandemic introduced the world to a different form of discrimination, and fast. An intense bias against the unvaccinated, even though the science revealed by late spring 2021 that the vaccine would not stop transmission. The primary benefit of COVID-19 vaccination is that it reduced the chances of more severe symptoms leading to hospitalization or worse—but the protective effects didn’t last long hence the need for booster doses. As it’s been pointed out, vaccination is a medical procedure, and in most cases a patient has a right to participate or not participate. However, moves made by governments and private entities around the world to encourage vaccination are leading to severe restrictions on those who choose to refuse the vaccine.

In many cases a vaccine mandate was a condition of employment and resulted in lawsuits by public servants. Such vaccination requirements are actually nothing new once a vaccine has been established as safe and effective. Persons employed by the military or in health systems traditionally were required to take certain vaccines. Of course, the childhood vaccination schedule has critical vaccine recommendations adopted as mandatory by schools.

But in the case of COVID-19 with a rapidly-developed, non-sterilizing vaccine (doesn’t stop the transmission) substantial numbers were cautious or “hesitant”. About 30% of the U.S. population opted to not receive the COVID-19 vaccine. Just under 20% of Canada’s population decided to not receive the vaccines. One of those persons was a nurse now suing a healthcare provider in Canada, claiming she was wrongfully dismissed because of her views on vaccination and the Covid-19 pandemic.

Concerns About how the Pandemic was “Managed”

Debra Carritt was employed in the healthcare sector since 1993 as an emergency medical technician and paramedic. In 2012 she started working as a nurse for the Alberta Health System (AHS). She then rose to the level of a unit manager. When the pandemic hit in 2020, Carritt voiced concerns about the way AHS was handling the crisis. She was subsequently dismissed for her opinion the health system had “open discrimination judgement and hostility toward” unvaccinated patients and staff and treated them with “harassment and discrimination.” Carritt alleges AHS tried to coerce the staff into getting vaccinated.

Filed a Lawsuit After Dismissal

In September of 2021 Carritt wrote a letter to the Chief Executive Officer of AHS claiming the provincial health system was mismanaging the crisis which led to bed shortages because AHS was “supporting fear mongering by media agencies and the government by recording and sharing daily virus infection statistics despite similar statistics not being kept and shared for any previous infectious disease outbreaks”.

These concerns were outlined in both her letters, which received no response from management. After getting no response Carritt sent another letter six days later. That letter also was shunned by AHS. Carritt then gave an online interview because she felt she “had exhausted all of the formal grievance and reporting mechanisms.” The interview was conducted with a media organization labelled right wing. She was fired in December of 2021.

44 Page Claim

According to the 44 page “statement of claim” filed by Carritt with the Court of King’s Bench in Calgary, Alberta AHS failed “to acknowledge or comprehend the adverse health effects members of the public would experience though continued 'fight or flight' reactions experienced as a result of those individuals living with a continued heightened sense of fear through conditions AHS created".

Regarding her interview, the claim says, "Mrs. Carritt expressly denies that her representations and conduct during the interview violated the (social media and e-professionalism guidelines) as alleged or at all. In the alternative, Mrs. Carritt states, and the fact is, that her representations and conduct during the interview met and exemplified the standards in those guidelines by, among other things, complying with her 'professional and ethical obligations to protect the public and maintain conduct that reflects trustworthiness.” She is seeking over $420,000 in lost pay and another $250,000 in punitive damages as well as $3 million for alleged negligence. The lawsuit was filed on March 17, 2023.

Received a Disciplinary Note

In January of 2022, Carritt received a disciplinary note from the College & Association of Registered Nurses of Alberta saying Carritt "failed to demonstrate adequate judgement and failed to demonstrate a professional presence" during her media interview. The note continues saying Carritt made statement regarding the Covid-19 pandemic, Covid-19 vaccination and related issues that did not align with one or more employer policies and that were potentially misleading, after identifying herself as a registered nurse and that she worked as a unit manager working for a major health authority."

According to the note Carritt agreed to complete a “reflexive essay” and pay a fine. For whatever reason, during the Covid crisis, even with authorities claiming concern about public health and public safety, when healthcare workers voiced opinions about rules and mandates, concern got tossed, as employers and governments followed rigid, hierarchical marching orders.
