Universal Control of Symmetric States Using Spin Squeezing.

The manipulation of quantum many-body systems is a crucial goal in quantum science. Entangled quantum states that are symmetric under qubits permutation are of growing interest. Yet, the creation and control of symmetric states has remained a challenge.

Restoration of the sagittal profile according to the Roussouly classification reduces mechanical complications and revision surgery in older patients undergoing surgery for adult spinal deformity (ASD).

Purpose: The mechanical complications related to ASD remain a concern due to their morbidity and associated revision surgery. Restoration of each patient's Roussouly profile may reduce these. Our aim was to examine if the restoration of the Roussouly profile reduced these complications and revision rates in older patients operated for degenerative ASD.

Country versus pharmaceutical company interests for hepatitis C treatment.

Hepatitis C virus (HCV) is one of the leading causes of liver disease and is responsible for massive health and economic burden worldwide. The disease is asymptomatic in its early stages, but it can progress over time to fatal end-stage liver disease. Thus, the majority of individuals infected with HCV are unaware of their chronic condition.

Eosinophilic Myocarditis in a Patient With Sickle Cell Disease.

A 23-year-old man with sickle cell disease treated with splenectomy and allogenic stem cell transplantation presented with recurrent chest pain, elevated cardiac enzymes, and unremarkable electrocardiography. His work-up revealed eosinophilia, raising concern for eosinophilic myocarditis. Cardiac magnetic resonance imaging showed patchy late gadolinium enhancement of the left ventricular free wall, suggestive of myocarditis.
