Sir William Osler is one of the most admired and honored physicians in the history of medicine. He influenced the development of medicine in Canada, the United States, and Great Britain, where he held professorships at McGill University, the University of Pennsylvania, Johns Hopkins University, and Oxford University. ⋯ In this sesquicentennial of his birth, William Osler continues to serve as a model of excellence for the medical profession. This examination of the reasons for his enduring impact reveals a legacy of clinical, scientific, literary, educational, and intraprofessional accomplishments linked to a remarkable personality, and bound together by an extraordinary humanism.

Acquired immunodeficiency syndrome-related opportunistic illnesses (Ols) continue to occur after initiation of potent antiretroviral therapy in patients with human immunodeficiency virus (HIV) infection. Risk factors for clinical progression to Ols during potent therapy are not well defined. ⋯ Our data indicate that the risk of developing an OI for a person receiving potent antiretroviral therapy is highest during the initial months of therapy. Baseline CD4 cell count and immunologic and virologic response to treatment were strong predictors of disease progression in patients receiving potent therapy. Individuals with CD4 cell counts of 50 x 10(6)/L or below may need close clinical surveillance after initiation of potent therapy.

There is strong consensus that caring for an elderly individual with disability is burdensome and stressful to many family members and contributes to psychiatric morbidity. Researchers have also suggested that the combination of loss, prolonged distress, the physical demands of caregiving, and biological vulnerabilities of older caregivers may compromise their physiological functioning and increase their risk for physical health problems, leading to increased mortality. ⋯ Our study suggests that being a caregiver who is experiencing mental or emotional strain is an independent risk factor for mortality among elderly spousal caregivers. Caregivers who report strain associated with caregiving are more likely to die than noncaregiving controls.

Human adipose tissue expresses and releases the proinflammatory cytokine interleukin 6, potentially inducing low-grade systemic inflammation in persons with excess body fat. ⋯ Higher BMI is associated with higher CRP concentrations, even among young adults aged 17 to 39 years. These findings suggest a state of low-grade systemic inflammation in overweight and obese persons.

The mean body weight of US adults increased by 3.6 kg (7.6 lb) during the past 15 years, but few studies exist that examine the impact of such weight change on functional health status. ⋯ These longitudinal data support current US guidelines for women of all body mass index levels to avoid weight gain. Weight maintenance and, in cases of overweight, weight loss are desirable and likely to be beneficial for physical function, vitality, and bodily pain.
