What the authors write

Paul Clayton

COVID-related lockdowns were said to have led to an increase in diabetes cases.

„The COVID-related lockdowns, which caused a predictable increase in diabetes cases (46, 47), will provide another downward blow. The next generation will probably be even more affected. Recent evidence of greatly slowed verbal, motor, and overall cognitive development in children born during isolation is deeply worrying.”Lockdowny związane z COVID-em, które spowodowały przewidywalny wzrost zachorowań na cukrzycę (46, 47), zapewnią kolejne strącenie w dół. Następna generacja prawdopodobnie będzie jeszcze bardziej dotknięta. Niedawne dowody na znacznie spowolniony rozwój werbalny, motoryczny i ogólny rozwój poznawczy u dzieci urodzonych podczas izolacji są głęboko niepokojące.

Slower development of speech, motor skills, and cognitive abilities has been reported in children born during isolation.

„Recent evidence of greatly slowed verbal, motor, and overall cognitive development in children born during isolation is deeply worrying. Will these children, whose cognitive scores fell by a staggering 2 standard deviations (48), ever catch up?”Niedawne dowody na znacznie spowolniony rozwój werbalny, motoryczny i ogólny rozwój poznawczy u dzieci urodzonych podczas izolacji są głęboko niepokojące. Czy te dzieci, których wyniki poznawcze spadły o oszałamiające 2 odchylenia standardowe (48), kiedykolwiek nadrobią zaległości?

Social isolation is linked to an increased risk of stroke and dementia.

„Isolation is linked to a 30 percent higher risk of stroke (53) and a 50 percent higher risk of dementia (54, 55). The cause is probably primarily isolation -> inflammation -> stroke and dementia, but the reverse also occurs.”Izolacja wiąże się ze zwiększonym o 30 proc. ryzykiem udaru mózgu (53) i o 50 proc. zwiększonym ryzykiem demencji (54, 55). Przyczyną jest prawdopodobnie przede wszystkim izolacja -> stan zapalny -> udar i demencja, ale istnieje również odwrotność sytuacji.

Jerzy Zięba

Jerzy Zięba believes that the air under a mask is unfit to breathe and may pose a threat to health and life.

„Such a measurement will clearly show that the air under a mask is in no way fit for humans to breathe! Dozens of such measurements have been carried out and published online. However, they were not carried out by a government organization authorized to do so.”Z takiego pomiaru wyniknie jednoznacznie, że powietrze pod maseczką w żadnym przypadku nie nadaje się do oddychania przez człowieka! Pomiarów takich dokonano dziesiątki i są opublikowane w Internecie. Nie były to jednak pomiary robione przez uprawnioną do tego organizację rządową.
COVID-19. Jak to zatrzymać?
Dr Astrid Stuckelberger

Dr Astrid Stuckelberger claims that masks can cause bacterial pneumonia.

„They have lied from PCR to everything they have created, tests, terror, I call it, the public health lockdown, the tyranny of masks, The mask create pneumonia, bacterial pneumonia. Even Fauci wrote that, that the Spanish flu is because of the masks of bacterial pneumonia.”They have lied from PCR to everything they have created, tests, terror, I call it, the public health lockdown, the tyranny of masks, The mask create pneumonia, bacterial pneumonia.

Henryk Różański

Henryk Różański presents masks as filters that are meant to trap dust, bacteria, and viruses and protect the respiratory system.

„Let us remember that human secretions and excretions turn into dust and dirt over time. Carried by air currents, this dust settles on various surfaces, and we breathe it in, just as animals do. A protective mask will prevent viruses from entering the respiratory system, not only in the event of direct exposure to aerosols expelled when a potentially sick person coughs or sneezes, but also when dust is stirred up.”Pamiętajmy, że wydzieliny i wydaliny ludzi zamieniają się z czasem w pył i kurz, który wzniesiony przez ruchy powietrza osadza się różnych powierzchniach i my ten kurz wdychamy, podobnie jak zwierzęta. Maseczka ochronna zapobiegnie przedostaniu się do układu oddechowego wirusów, nie tylko w razie bezpośredniego narażenia na aerozol wyrzucony w czasie kaszlu/kichania osoby potencjalnie chorej, ale również w razie uniesienia się kurzu.
SARS-CoV-2 i COVID-19. Wolne przemyślenia.
Jerzy Zięba

Jerzy Zięba claims that masks made no difference to the number of infections.

„This document clearly states that wearing masks, using gloves, or cleaning surfaces with disinfectants made no difference to infections with the virus. In other words, these measures simply do not work. Physical studies of mask effectiveness—that is, studies on how viruses pass through masks—also clearly showed that their effectiveness is practically zero.”Dokument ten jednoznacznie stwierdza, że noszenie maseczek, stosowanie rękawiczek czy mycie powierzchni płynami dezynfekującymi nie spowodowało żadnej różnicy w zakażeniach wirusem. Czyli środki te po prostu nie działają. Badania fizyczne skuteczności maseczek, czyli badania dotyczące przenikania wirusa przez maseczki, również jednoznacznie wskazały, że ich skuteczność jest praktycznie zerowa.
Co z tą pandemią?
Jerzy Zięba

Jerzy Zięba cites 67 studies and claims that masks are completely ineffective.

„He has 67 scientific studies stating that the effectiveness of wearing masks is… zero. Why, then, did the relevant authorities not immediately introduce regulations lifting the mask-wearing requirement? If wearing masks makes no sense in light of the research, why are politicians, and especially members of parliament, taking part in this idiotic masquerade?”Dysponuje on 67 badaniami naukowymi, które stwierdzają, że skuteczność noszenia maseczek jest… zerowa. Dlaczego więc odpowiednie urzędy natychmiast nie wprowadziły przepisów, które zdejmują nakaz ich noszenia? Skoro w świetle badań noszenie maseczek jest pozbawione sensu, to dlaczego politycy, a w szczególności posłowie, biorą udział w tej idiotycznej maskaradzie?
System w panice
Dr Astrid Stuckelberger

Dr Astrid Stuckelberger links lockdowns and masks to causing fear and mental health problems.

„So they made a deception and they created this crazy psychological fear, mental health problem, that if you are not sick and not coughing, you might not know that you are sick. So you go in a shop and they say, you wear a mask. I say, I'm not sick, I'm healthy.”So they made a deception and they created this crazy psychological fear, mental health problem, that if you are not sick and not coughing, you might not know that you are sick.

Prof. Sucharit Bhakdi

Prof. Sucharit Bhakdi writes that experiences related to the pandemic, including lockdowns, fear, and mask-wearing, may be associated with PTSD.

„Holland, President and General Counsel (on leave), Children’s Health Defense Anyone alive today may be forgiven for experiencing PTSD (PostTraumatic Stress Disorder) about all things COVID—the lockdowns, the fear mongering, the masking, the testing, the censorship, the suppression of effective treatments, the coerced experimental gene-based shots, and the pervasive injuries and deaths.”Holland, President and General Counsel (on leave), Children’s Health Defense Anyone alive today may be forgiven for experiencing PTSD (PostTraumatic Stress Disorder) about all things COVID—the lockdowns, the fear mongering, the masking, the testing, the censorship, the suppression of effective treatments, the coerced experimental gene-based shots, and the pervasive injuries and deaths.

A meta-analysis found that the pandemic and lockdown were associated with a lower risk of surgical site infections, particularly superficial infections.

Aim of the study: Background: We aimed to summarize and synthesize the current evidence regarding the indirect impact of the coronavirus disease 2019 (COVID-19) pandemic and its associated measures on the surgical site infection (SSI) rate compared with the pre-pandemic period. Methods: A computerized search was conducted on MEDLINE via PubMed, Web of Science, and Scopus using the relevant keywords.

Results: There was no significant reduction in the SSIs rate after applying the extended use of masks (OR, 0.73; 95% CI, 0.30-1.73; p = 0.47). A reduction in the superficial SSI rate during the COVID-19 pandemic compared with the pre-COVID-19 pandemic period was observed (OR, 0.58; 95% CI, 0.45-0.75; p < 0.0001). Conclusions: The current evidence suggests that the COVID-19 pandemic may have some unexpected benefits, including improved infection control protocols, which resulted in reduced SSI rates, especially superficial SSIs. In contrast to extended mask use, the lockdown was associated with reduced rates of SSIs.

Fewer cases of many infectious diseases were reported during the pandemic, which the authors link, among other things, to lockdowns and mask use.

Aim of the study: COVID-19 pandemic has exerted a huge impact on different aspects of public health. Mandatory notifications are a fundamental tool to have a general picture of infection disease spread in a population. The aim of this study was to evaluate the impact the COVID-19 pandemic had on infectious disease epidemiology.

Results: The total number of notifications significantly decreased by 41% in the pandemic period compared to the pre-pandemic one, with very high reduction of certain disease notifications such as measles and varicella. Similarly, other airborne infections, such as meningococcal meningitis and tuberculosis, underwent an important decrease. Conversely, an increase was found for some infections such as syphilis and, especially, scabies that reported a percentage value of +159.9%. The COVID-19 pandemic, reducing the possibility of microbial spread following to the lockdown and, in addition, to the constant use of face masks and other personal protective equipment, the frequent hand-washing, more ventilation of the living locals, and less gathering, surely reduced the occasions and the possibility to get many infections.

A review found that pandemic restrictions improved air quality in some countries, partly by reducing pollutant emissions.

Aim of the study: The COVID-19 pandemic caused by SARS-CoV-2 has posed a huge threat to mankind, deeply endangering healthy states and influencing economic development. COVID-19 has important impacts on the environment as anthropic interventions to nature has been largely reduced after almost all countries implemented partial or complete blockade to curb the spread of the virus.

Results: For the general public, in addition to the physical lesions caused by SARS-CoV-2, confirmed/suspected cases and even the normal group may suffer from mental problems. Based on those mentioned impacts, the way forward depends largely on our attitude and decision. It is indispensable to assess potential deleterious effects and to take preventive measures in time to respond to the post-pandemic era. In this way, potential silver linings will not become temporary.

In a study of adolescents, more frequent use of preventive measures was associated with less severe depressive symptoms.

Aim of the study: The COVID-19 pandemic affected adolescent mental health. However, the concurrent associations among adolescents' preventive practices, parent-child conflict, and depressive symptoms during the initial lockdown remain unclear.

Results: A significant indirect association was observed through parent-child conflict such that greater engagement in preventive practices co-occurred with less parent-child conflict and fewer depressive symptoms. The negative direct association between preventive practices and depressive symptoms was stronger for boys, whereas the positive association between parent-child conflict and depressive symptoms was stronger for girls. However, these interaction terms added only ΔR2 = 0.003 and 0.004 in observed-score sensitivity models and were not statistically significant in the subsample sensitivity analysis. These findings identify parent-child conflict as a concurrent correlate of the association between preventive practices and depressive symptoms during the pandemic.

The account of Bergamo indicates that imposing a strict lockdown helped bring the epidemic under control and enabled the hospital to cope with the influx of seriously ill patients.

Aim of the study: The novel coronavirus, SARS-CoV-2, continues to spread rapidly. Here we discuss the dramatic situation created by COVID-19 in Italy, particularly in the province of Bergamo (the most severely affected in the first wave), as an example of how, in the face of an unprecedented tragedy, acting (albeit belatedly)-including imposing a very strict lockdown-can largely resolve the situation within approximately 2 months.

The measures taken here ensured that Bergamo hospital, which was confronted with rapidly rising numbers of severely ill COVID-19 patients requiring hospitalization, was able to meet the initial challenges of the pandemic. We also report that local organization and, more important, the large natural immunity against SARS-CoV-2 of the Bergamo population developed during the first wave of the epidemic, can explain the limited number of new COVID-19 cases during the more recent second wave compared to the numbers in other areas of Lombardy.
