Randomized Controlled Trial Comparative Study Clinical Trial
Heparin-induced thrombocytopenia in patients treated with low-molecular-weight heparin or unfractionated heparin.
Heparin-induced thrombocytopenia, defined by the presence of heparin-dependent IgG antibodies, typically occurs five or more days after the start of heparin therapy and can be complicated by thrombotic events. The frequency of heparin-induced thrombocytopenia and of heparin-dependent IgG antibodies, as well as the relative risk of each in patients given low-molecular-weight heparin, is unknown. ⋯ Heparin-induced thrombocytopenia, associated thrombotic events, and heparin-dependent IgG antibodies are more common in patients treated with unfractionated heparin than in those treated with low-molecular-weight heparin.

Comparative Study
The prevalence of blindness and visual impairment among nursing home residents in Baltimore.
Although the prevalence of blindness and visual impairment increases with age, most surveys of ocular disease do not include nursing home residents. ⋯ Blindness and visual impairment are highly prevalent among nursing home residents. Much of this loss of vision could be treated or prevented with appropriate ophthalmologic care.
