Medicare gaps and widow poverty.
Several categories of medical expenditures are not covered by Medicare, including prescription drugs, most nursing home stays, and extended hospital visits. Out-of-pocket costs for these items can be substantial, and what’s more, they are likely to be concentrated at the end of life. At the same time, it is well documented that poverty is 3-4 times more common among widows than among similarly ...
متن کاملBlack widow spider bite.
These two cases illustrate many classical features of latrodectism. A subclinical bite followed by extensive systemic signs and symptoms in a recognizable pattern is strongly suggestive of the diagnosis. Pain and muscle spasms are refractory to standard therapy but are relieved by intravenous calcium. Finally, there should be complete resolution of the symptoms after only one vial of antivenin ...
متن کاملEvolution of Black Widow Pulsars
We consider the evolution of black widow pulsars (BWPs). The large majority of these are members of globular clusters. For minimum companion masses < 0.1M ̄, adiabatic evolution and consequent mass loss under gravitational radiation appear to provide a coherent explanation of all observable properties. We suggest that the group of BWPs with minimum companion masses ∼> 0.1M ̄ are systems relaxing ...
متن کاملThe prevalence of brown widow and black widow spiders (Araneae: Theridiidae) in urban southern California.
The brown widow spider, Latrodectus geometricus C. L. Koch, has become newly established in southern California during the first decade of the 21st century. Brown widows and egg sacs were collected within the urban Los Angeles Basin using timed searches. We also collected and compared the abundance and distribution of the native western black widow spider, Latrodectus hesperus Chamberlin & Ivie...
متن کاملBlack Widow Pulsars: the Price of Promiscuity
The incidence of evaporating ‘black widow’ pulsars (BWPs) among all millisecond pulsars (MSPs) is far higher in globular clusters than in the field. This implies a special formation mechanism for them in clusters. Cluster MSPs in wide binaries with WD companions exchange them for turnoff–mass stars. These new companions eventually overflow their Roche lobes because of encounters and tides. The ...
