Excess mortality has been observed in several countries since 2021 and has not yet been explained. The aim of this study was to determine whether the age-adjusted mortality rates of non-COVID-19 deaths differed between those who had received one, two, three or four doses compared with the unvaccinated. Data were obtained from the Office for… Continue reading Age-adjusted non-COVID-19 #mortality rates according to the #COVID-19 vaccination status

Impact of #mRNA and Inactivated COVID-19 Vaccines on #Ovarian Reserve
Objectives: This study aimed to elucidate the effects of messenger RNA (mRNA) and inactivated coronavirus disease 2019 (COVID-19) vaccines on ovarian histology and reserve in rats. Methods: Thirty female Wistar albino rats, aged 16–24 weeks, were randomly divided into three groups (n = 10): control, mRNA vaccine, and inactivated vaccine groups. Each vaccine group received… Continue reading Impact of #mRNA and Inactivated COVID-19 Vaccines on #Ovarian Reserve
Deaths “due to” #COVID-19 and deaths “with” COVID-19 during the #Omicron variant surge, among hospitalized patients in seven tertiary-care hospitals, Athens, Greece
In Greek hospitals, all deaths with a positive SARS-CoV-2 test are counted as COVID-19 deaths. Our aim was to investigate whether COVID-19 was the primary cause of death, a contributing cause of death or not-related to death amongst patients who died in hospitals during the Omicron surge and were registered as COVID-19 deaths. Additionally, we… Continue reading Deaths “due to” #COVID-19 and deaths “with” COVID-19 during the #Omicron variant surge, among hospitalized patients in seven tertiary-care hospitals, Athens, Greece
Repeated #COVID-19 #Vaccination as a Poor Prognostic Factor in Pancreatic #Cancer: A Retrospective, Single-Center Cohort Study
AbstractThe COVID-19 vaccine is a significant technological advancement with widespread global use. However, its effect on cancer immunity, particularly with repeated vac-cinations, remains unclear. We aimed to investigate the relationship between repeated vaccinations and pancreatic cancer (PC) prognosis. Additionally, we examined serum IgG4 levels, known to be an immune suppressor and increased with repeated vac-cinations.… Continue reading Repeated #COVID-19 #Vaccination as a Poor Prognostic Factor in Pancreatic #Cancer: A Retrospective, Single-Center Cohort Study
COVID-19 #vaccines and #adverse events of special interest: A multinational Global Vaccine Data Network (GVDN) cohort study of 99 million vaccinated individuals
AbstractBackground: The Global COVID Vaccine Safety (GCoVS) Project, established in 2021 under the multinational Global Vaccine Data Network™ (GVDN®), facilitates comprehensive assessment of vaccine safety. This study aimed to evaluate the risk of adverse events of special interest (AESI) following COVID-19 vaccination from 10 sites across eight countries.Methods: Using a common protocol, this observational cohort… Continue reading COVID-19 #vaccines and #adverse events of special interest: A multinational Global Vaccine Data Network (GVDN) cohort study of 99 million vaccinated individuals
Healthy #sleep patterns and risk of hospitalization for #infection: a large community-based cohort study
Sleep behaviours are potentially modifiable risk factors for infectious disease. However, little is known about the combined effects of multiple sleep factors on the risk of infections. We investigated the prospective associations of combined healthy sleep patterns with the risk of hospitalization for infection in 397,523 participants (mean (SD) age: 56.3 (8.1) years) from the… Continue reading Healthy #sleep patterns and risk of hospitalization for #infection: a large community-based cohort study
Intestinal #Microbiota Contributes to the Development of #Cardiovascular Inflammation and Vasculitis in Mice
Alterations in the intestinal microbiota contribute to the pathogenesis of various cardiovascular disorders, but how they affect the development of Kawasaki disease (KD) an acute pediatric vasculitis, remains unclear.METHODS:We used the Lactobacillus casei cell wall extract (LCWE) murine model of KD vasculitis to assess the contribution of the intestinal microbiota to the development of vascular… Continue reading Intestinal #Microbiota Contributes to the Development of #Cardiovascular Inflammation and Vasculitis in Mice
#Probiotics and #Fever Duration in Children With Upper Respiratory Tract Infections
Importance Upper respiratory tract infections (URTIs) are prevalent in children, prompting frequent health care consultations, especially among those with fever. Probiotics show potential as an adjuvant treatment for URTIs, but evidence in children is limited.Objective To evaluate the efficacy of a probiotic mixture containing Bifidobacterium breve M-16V, Bifidobacterium lactis HN019, and Lactobacillus rhamnosus HN001 in… Continue reading #Probiotics and #Fever Duration in Children With Upper Respiratory Tract Infections
The protective role of vitamin #D in BNT162b2 vaccine-related acute #myocarditis
Introduction: Vaccine-related myocarditis is recognized as a rare but important complication, especially after mass-scale mRNA COVID-19 vaccination. Knowledge regarding how to minimize the risk is limited. As NK cells can mediate acute myocarditis after mRNA COVID-19 vaccination and vitamin D may inhibit NK cells via cytokine modulation, we hypothesize that the myocarditis side effect is… Continue reading The protective role of vitamin #D in BNT162b2 vaccine-related acute #myocarditis
