Degradation and de novo formation of nine major glucose degradation products during storage of peritoneal dialysis fluids.

Reactive glucose degradation products (GDPs) are formed during heat sterilization of glucose-containing peritoneal dialysis fluids (PDFs) and may induce adverse clinical effects. Long periods of storage and/or transport of PDFs before use may lead to de novo formation or degradation of GDPs. Therefore, the present study quantified the GDP profiles of single- and double-chamber PDFs during storage.

Physical Activity and Different Concepts of Fall Risk Estimation in Older People--Results of the ActiFE-Ulm Study.

Objectives: To investigate the relationship between physical activity and two measures of fall incidence in an elderly population using person-years as well as hours walked as denominators and to compare these two approaches.

Design: Prospective cohort study with one-year follow-up of falls using fall calendars. Physical activity was defined as walking duration and recorded at baseline over one week using a thigh-worn uni-axial accelerometer (activPAL; PAL Technologies, Glasgow, Scotland).

Serum Vitamin D Concentrations and Cognitive Function in a Population-Based Study among Older Adults in South Germany.

Our objective was to investigate the associations of vitamin D serum levels with dementia and cognitive function in specific domains in community dwelling older adults. Between 2009 and 2010, we conducted a cross-sectional study in 1,373 individuals (56% men) aged 65+ years in the "Activity and Function in the Elderly in Ulm" (ActiFE) study. Dementia was defined as a Mini-Mental State Examination (MMSE) score ≤ 24.

Predicting fatigue in older breast cancer patients receiving radiotherapy. A head-to-head comparison of established assessments.

Objectives: Because of substantial toxicities in older adults, chemotherapy is often omitted while the frequency of radiotherapy changes only minimally. In this study, we addressed the value of different assessments for predicting fatigue after radiotherapy in older breast cancer patients.

Patients And Methods: We included 74 women with primary breast cancer over the age of 65 years treated with radiotherapy (26 % with additional chemotherapy).

Objectively measured physical activity and vitamin D status in older people from Germany.

Background: To analyse the seasonal relationship of objectively measured physical activity with vitamin D status in older persons from Southern Germany (latitude: 48.4°N).

Methods: Physical activity was assessed in 1193 community-dwelling individuals aged ≥65 years (58% men) over 1 week using a thigh-worn accelerometer.
