Risk of SARS-CoV-2 reinfection and COVID-19 hospitalisation in individuals with natural and hybrid immunity: a retrospective, total population cohort study in Sweden

Real-world evidence supporting vaccination against COVID-19 in individuals who have recovered from a previous SARS-CoV-2 infection is sparse. We aimed to investigate the long-term protection from a previous infection (natural immunity) and whether natural immunity plus vaccination (hybrid immunity) was associated with additional protection. MethodsIn this retrospective cohort study, we formed three cohorts using Swedish… Continue reading Risk of SARS-CoV-2 reinfection and COVID-19 hospitalisation in individuals with natural and hybrid immunity: a retrospective, total population cohort study in Sweden

Risk and severity of SARS-CoV-2 reinfections during 2020-2022 in Vojvodina, Serbia: a population-level study

AbstractBackground: Data on the rate and severity of reinfections with SARS-CoV-2 in real-world settings are scarce and the effects of booster vaccination on reinfection risk are unknown. Methods: In a retrospective cohort study, all SARS-CoV-2 laboratory-confirmed residents of Vojvodina, registered in the database of the Institute of Public Health of Vojvodina, between March 6, 2020… Continue reading Risk and severity of SARS-CoV-2 reinfections during 2020-2022 in Vojvodina, Serbia: a population-level study

Detection of microplastics in human lung tissue using μFTIR spectroscopy

AbstractAirborne microplastics (MPs) have been sampled globally, and their concentration is known to increase in areas of high human population and activity, especially indoors. Respiratory symptoms and disease following exposure to occupational levels of MPs within industry settings have also been reported. It remains to be seen whether MPs from the environment can be inhaled,… Continue reading Detection of microplastics in human lung tissue using μFTIR spectroscopy

The Impact of Face-Masks on Total Mortality Heterogenous Effects by Gender and Age

AbstractGovernments around the world have been implementing several non-pharmaceutical interventions (NPIs) to fight Covid-19 spread and its associated mortality. We estimate the causal impact of mandatory face-mask wearing policy in public places on (total) mortality in Switzerland. We exploit the staggered introduction of the policy across Swiss cantons using a Difference-in-Difference and an event study… Continue reading The Impact of Face-Masks on Total Mortality Heterogenous Effects by Gender and Age

Association of Lithium Treatment With the Risk of Osteoporosis in Patients With Bipolar Disorder

Importance Osteoporosis, a systemic skeletal disorder associated with substantial morbidity and mortality, may be particularly common among individuals with bipolar disorder. Lithium, a first-line mood-stabilizing treatment for bipolar disorder, may have bone-protecting properties. Objective To evaluate if treatment with lithium is associated with a decrease in risk of osteoporosis among patients with bipolar disorder. Design,… Continue reading Association of Lithium Treatment With the Risk of Osteoporosis in Patients With Bipolar Disorder

Mechanical control of innate immune responses against viral infection revealed in a human lung alveolus chip

AbstractMechanical breathing motions have a fundamental function in lung development and disease, but little is known about how they contribute to host innate immunity. Here we use a human lung alveolus chip that experiences cyclic breathing-like deformations to investigate whether physical forces influence innate immune responses to viral infection. Influenza H3N2 infection of mechanically active… Continue reading Mechanical control of innate immune responses against viral infection revealed in a human lung alveolus chip

Avocado Consumption and Risk of Cardiovascular Disease in US Adults

AbstractBackgroundEpidemiologic studies on the relationship between avocado intake and long‐term cardiovascular disease (CVD) risk are lacking. Methods and ResultsThis study included 68 786 women from the NHS (Nurses’ Health Study) and 41 701 men from the HPFS (Health Professionals Follow‐up Study; 1986–2016) who were free of cancer, coronary heart disease, and stroke at baseline. Diet… Continue reading Avocado Consumption and Risk of Cardiovascular Disease in US Adults

Effects of Caffeine Consumption on Attention Deficit Hyperactivity Disorder (ADHD) Treatment: A Systematic Review of Animal Studies

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by a persistent pattern of inattention and/or hyperactivity-impulsivity. ADHD impairments arise from irregularities primarily in dopamine (DA) and norepinephrine (NE) circuits within the prefrontal cortex. Due to ADHD medication’s controversial side effects and high rates of diagnosis, alternative/complementary pharmacological therapeutic approaches for ADHD are needed.… Continue reading Effects of Caffeine Consumption on Attention Deficit Hyperactivity Disorder (ADHD) Treatment: A Systematic Review of Animal Studies

EARLY OUTPATIENT TREATMENT OF COVID-19: A RETROSPECTIVE ANALYSIS OF 392 CASES IN ITALY

AbstractIntroduction The pandemic of severe acute respiratory syndrome (SARS)-coronavirus-2 (CoV-2) disease 2019 (COVID-19) was declared in march 2020. Knowledge of COVID-19 pathophysiology soon provided a strong rationale for the early use of anti-inflammatory, antiplatelet and anticoagulant drugs, however the evidence was only slowly and partially incorporated into institutional guidelines. Unmet needs of COVID-19 outpatients were… Continue reading EARLY OUTPATIENT TREATMENT OF COVID-19: A RETROSPECTIVE ANALYSIS OF 392 CASES IN ITALY
