BACKGROUND Hypothyroidism is a common condition, particularly in the older population. Thyroid hormone requirements change with age and serum TSH levels also alter, especially in older patients. However, in practice laboratory reference ranges for thyroid function are not age-specific and treatment in older patients aims to achieve a similar target thyroid function level as younger age groups. ...

In the first two experiments, 380 participants in three age groups (20s, 60s, and 80+) were given a naturalistic PM task of logging the time at four set times for one week. There were six between-subjects regimens that varied the complexity of the time ...
BACKGROUND AND OBJECTIVES It has been suggested that reduced estimated GFR (eGFR) among older adults does not necessarily reflect a pathologic phenomenon. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We examined the association between eGFR and albumin-to-creatinine ratio (ACR) and all-cause mortality stratified by age (45 to 59.9, 60 to 69.9, 70 to 79.9, and ≥80 years) among 24,350 U.S. adu...
BACKGROUND/AIMS The aim of this study was to determine the decline in the estimated glomerular filtration rate (eGFR) in elderly persons and to compare estimates based on creatinine and cystatin C. METHODS In the Cardiovascular Health Study, GFR changes in an elderly cohort were estimated from serum creatinine and cystatin C measured at baseline, year 3 and year 7 in 4,380 participants (age 7...
