AbstractAsymptomatic blood donors can transmit human parvovirus B19 (B19V). We assessed the B19V prevalence amongst a large cohort of blood donations collected in Germany during 2015-2018. In total, 167,123 donations were screened for B19V DNA with 22 cases of viraemia identified (0.013% positive). Infections peaked at a four-year interval and the highest number of cases… Continue reading Prevalence of parvovirus B19 viraemia among German blood donations and the relationship to ABO and Rhesus blood group antigens

Migration of Microplastics and Phthalates from Face Masks to Water
Since the outbreak of COVID-19, face masks have been introduced in the complex strategy of infection prevention and control. Face masks consist of plastic polymers and additives such as phthalates. The aim of this study was to evaluate the migration of microplastics (MP) and phthalates from face masks to water. Four types of masks including… Continue reading Migration of Microplastics and Phthalates from Face Masks to Water
FDA urged to publish follow-up studies on covid-19 vaccine safety signals
The FDA has been criticised for taking more than a year to follow up a potential increase in serious adverse events in elderly people receiving Pfizer’s covid-19 vaccine, Maryanne Demasi reportsIn July 2021 the US Food and Drug Administration (FDA) quietly disclosed findings of a potential increase in four types of serious adverse events in elderly people… Continue reading FDA urged to publish follow-up studies on covid-19 vaccine safety signals
The Incidence of Myocarditis and Pericarditis in Post COVID-19 Unvaccinated Patients—A Large Population-Based Study
Myocarditis and pericarditis are potential post-acute cardiac sequelae of COVID-19 infection, arising from adaptive immune responses. We aimed to study the incidence of post-acute COVID-19 myocarditis and pericarditis. Retrospective cohort study of 196,992 adults after COVID-19 infection in Clalit Health Services members in Israel between March 2020 and January 2021. Inpatient myocarditis and pericarditis diagnoses… Continue reading The Incidence of Myocarditis and Pericarditis in Post COVID-19 Unvaccinated Patients—A Large Population-Based Study
Early Outpatient Treatment of COVID-19: A Retrospective Analysis of 392 Cases in Italy
COVID-19 was declared a pandemic in March 2020. The knowledge of COVID-19 pathophysiology soon provided a strong rationale for the early use of both anti-inflammatory and antithrombotic drugs; however, its evidence was slowly and partially incorporated into institutional guidelines. The unmet needs of COVID-19 outpatients were taken care of by networks of physicians and researchers.… Continue reading Early Outpatient Treatment of COVID-19: A Retrospective Analysis of 392 Cases in Italy
COVID UPDATE: What is the truth?
The COVID-19 pandemic is one of the most manipulated infectious disease events in history, characterized by official lies in an unending stream lead by government bureaucracies, medical associations, medical boards, the media, and international agencies.We have witnessed a long list of unprecedented intrusions into medical practice, including attacks on medical experts, destruction of medical careers… Continue reading COVID UPDATE: What is the truth?
Potential Mechanisms for Human Genome Integration of Genetic Code from SARS-CoV-2 mRNA Vaccination Potential Mechanisms for Human Genome Integration of Genetic Code from SARS-CoV-2 mRNA Vaccination
Abstract: Background The findings of a sequence embedded in Human DNA that was almost identical to a sequence in the SARS-CoV-2 genome, and the identification of plausible integration of SARS-CoV-2 RNA into human DNA by endogenous reverse transcriptase activity expressed by Long Interspersed Nuclear Element (LINE)-1 (17% of Human DNA) have raised concerns about the… Continue reading Potential Mechanisms for Human Genome Integration of Genetic Code from SARS-CoV-2 mRNA Vaccination Potential Mechanisms for Human Genome Integration of Genetic Code from SARS-CoV-2 mRNA Vaccination
Zoster-Associated Prothrombotic Plasma Exosomes and Increased Stroke Risk
Herpes zoster (HZ; shingles) caused by varicella zoster virus reactivation increases stroke risk for up to 1 year after HZ. The underlying mechanisms are unclear, however, the development of stroke distant from the site of zoster (eg, thoracic, lumbar, sacral) that can occur months after resolution of rash points to a long-lasting, virus-induced soluble factor… Continue reading Zoster-Associated Prothrombotic Plasma Exosomes and Increased Stroke Risk
SARS-CoV-2—The Role of Natural Immunity: A Narrative Review
Background: Both natural immunity and vaccine-induced immunity to COVID-19 may be useful to reduce the mortality/morbidity of this disease, but still a lot of controversy exists. Aims: This narrative review analyzes the literature regarding these two immunitary processes and more specifically: (a) the duration of natural immunity; (b) cellular immunity; (c) cross-reactivity; (d) the duration… Continue reading SARS-CoV-2—The Role of Natural Immunity: A Narrative Review
