Archives of Internal Medicine Study Highlights

  • Loneliness in individuals over 60 years of age appears associated with an increased risk of functional decline and death in a study that included 1,604 participants from the Health and Retirement Study (Online First, see news release below).
  • Living alone was associated with an increased risk of death and cardiovascular death in an international study of stable outpatients at risk of or with arterial vascular disease (e.g., coronary disease or peripheral vascular disease) (Online First, see news release below).
  • A study that evaluated the ability of the 6-minute walk test (6MWT) to predict heart failure, myocardial infarction (heart attack) and death suggests that shorter distance walked on the 6MWT was associated with higher rates of all three, independent of traditional cardiovascular disease risk factors and markers of cardiac disease severity (Online First).
  • According to a research letter, an anonymous survey of 150 resident physicians that asked whether they had worked when they were ill with flulike symptoms in the prior training year found that 77 (51 percent) worked with such symptoms at least once in the last year and 24 (16 percent) reported working sick at least three times (Online First).
  • According to a research letter, an analysis of hospitalization rates and in-hospital mortality among individuals at least 100 years old using 2004-2008 hospital discharge information shows a hospitalization rate of over 50 admissions per 100 centenarians and 90 percent survived the hospitalization (Online First).
