Effect of Cash Benefits on Health Care Utilization and Health: A Randomized Study.

Importance: Poverty is associated with greater barriers to health care and worse health outcomes, but it remains unclear whether income support can improve health.

Objective: To examine the effect of cash benefits on health care utilization and health.

Design, Setting, And Participants: The City of Chelsea, Massachusetts, a low-income community near Boston, randomly assigned individuals by lottery to receive cash benefits.

Termination of paroxysmal supraventricular tachycardia by intranasal swab insertion.

Paroxysmal supraventricular tachycardia (SVT) is a common emergency department presentation. Vagal maneuvers are commonly tried to terminate SVT but are often unsuccessful in terminating the dysrhythmia. The use of adenosine, while often successful, is associated with a number of side effects and is often disliked by patients with recurrent episodes of SVT.

What does "brainstem death" mean? A review of international protocols.

Purpose: The term "brainstem death" is ambiguous; it can be used to refer either exclusively to loss of function of the brainstem or loss of function of the whole brain. We aimed to establish the term's intended meaning in national protocols for the determination of brain death/death by neurologic criteria (BD/DNC) from around the world.

Methods: Of 78 unique international protocols on determination of BD/DNC, we identified eight that referred exclusively to loss of function of the brainstem in the definition of death.

Diffusive excitonic bands from frustrated triangular sublattice in a singlet-ground-state system.

Magnetic order in most materials occurs when magnetic ions with finite moments arrange in a particular pattern below the ordering temperature. Intriguingly, if the crystal electric field (CEF) effect results in a spin-singlet ground state, a magnetic order can still occur due to the exchange interactions between neighboring ions admixing the excited CEF levels. The magnetic excitations in such a state are spin excitons generally dispersionless in reciprocal space.
