Compared with temperate birds, tropical birds have low reproductive rates, slow development as nestlings, and long lifespans. These "slow" life history traits are thought to be associated with reduced energy expenditure, or a slow "pace of life." To test predictions from this hypothesis, we measured exercise-induced peak metabolic rates (PMR(E)) in 45 species of tropical lowland forest birds an...

INTRODUCTION The present study was conducted to determine whether patients with polymyalgia rheumatica (PMR) are at an increased risk of peripheral arterial disease (PAD). METHODS An inception cohort of all Olmsted County, Minnesota residents diagnosed with PMR between 1 January 1970 and 31 December 1999 was compared with non-PMR subjects (two for each PMR subject) from among residents. Both ...

Polymyalgia rheumatica (PMR) is relatively common among the elderly, and is characterized by multiple body aches with an elevated erythrocyte sedimentation rate. Even though the etiology of PMR remains unknown, a number of infectious agents have been suggested to cause PMR. Also, there are reports of PMR after influenza vaccination. The exact role of influenza vaccination on the development of ...

This study analyzed the relationships between the inclination to help the others and prosocial moral reasoning (PMR) in a sample of 548 Italian adolescents and young adults. We used the Italian version of Prosocial Tendencies Measure to evaluate the tendencies to adopt prosocial behaviors in different conditions (public, anonymous, and helping behavior in emotionally critical and dire situation...

OBJECTIVE To compare multiple serum markers for their ability to detect active disease in patients with GCA and in those with PMR. METHODS Twenty-six markers related to immune cells that may be involved in GCA and PMR were determined by ELISA and multiplex assay in the serum of 24 newly diagnosed, untreated GCA/PMR patients, 14 corticosteroid (CS)-treated GCA/PMR patients in remission and 13 ...

OBJECTIVE In this study, we evaluated clinical and epidemiologic features of our giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) patients. METHODS We retrospectively recorded down the general features of patients with GCA and PMR diagnosed at our center within the last 6 years. The incidence rates per 100000 aged > or =50 were calculated. In addition, we reported the frequencies o...

The diagnosis of polymyalgia rheumatica (PMR), characterized by proximal pain and stiffness, is often uncertain owing to PMR mimics, such as rheumatoid arthritis (RA), spondyloarthritides, inf lammatory myopathies connective tissue diseases and vasculitis – all of which can present with the polymyalgic syndrome in the elderly. Inflammatory markers are often discordant with disease activity and ...
