Longitudinal change in SARS-CoV-2 seroprevalence in 3-to 16-year-old children: The Augsburg Plus study.

Background: Currently, more than 30,200,000 COVID-19 cases have been diagnosed in Germany alone. However, data regarding prevalence of COVID-19 in children, both in Germany and internationally, are sparse. We sought to evaluate the number of infected children by measuring IgG antibodies.

Prevalence of chronic traumatic encephalopathy in the Sydney Brain Bank.

Chronic traumatic encephalopathy neuropathologic change can only be definitively diagnosed post-mortem. It has been associated with repetitive mild neurotrauma sustained in amateur and professional contact, collision and combat sports, although it has also been documented in people with a single severe traumatic brain injury and in some people with no known history of brain injury. The characteristic neuropathology is an accumulation of perivascular neuronal and astrocytic phosphorylated tau in the depths of the cortical sulci.

High-Fidelity Bell-State Preparation with ^{40}Ca^{+} Optical Qubits.

Entanglement generation in trapped-ion systems has relied thus far on two distinct but related geometric phase gate techniques: Mølmer-Sørensen and light-shift gates. We recently proposed a variant of the light-shift scheme where the qubit levels are separated by an optical frequency [B. C.

Effort-Reward Imbalance at Work and Overcommitment in Patients with Acute Myocardial Infarction (AMI): Associations with Return to Work 6 Months After AMI.

Purpose Stress-related factors influence the adaptation to life after acute myocardial infarction (AMI), including return to work. The goal of this study was to investigate the effect of work-related stress, (expressed by the effort-reward imbalance (ERI) model) on return to work after AMI. Methods A longitudinal study with AMI patients was conducted in order to assess associations between the independent variables effort, reward, ERI and overcommitment and the outcome return to work after AMI.
