Estimating arsenic biotransfer factors from feed to chicken: a viable approach to animal feed risk assessment.

Reliable biotransfer factor (BTF) data are critical for animal-feed studies in human risk assessment. A wide range of BTF values have been reported (0.0015-0.

Tubo-ovarian abscess with sepsis in a nonagenarian woman: a case report and literature review.

Background: A complete infectious focus survey relies on a thorough physical examination as well as a pelvic examination. Tubo-ovarian abscess, though less likely to occur in senior women, may become a life-threatening disease requiring emergent surgery. Hence, clinical awareness and aggressive management are warranted to avoid delayed diagnosis and subsequent complications.

Inhaled corticosteroids can reduce osteoporosis in female patients with COPD.

Background: Whether the use of inhaled corticosteroids (ICSs) in patients with COPD can protect from osteoporosis remains undetermined. The aim of this study is to assess the incidence of osteoporosis in patients with COPD with ICS use and without.

Patients And Methods: This is a retrospective cohort and population-based study in which we extracted newly diagnosed female patients with COPD between 1997 and 2009 from Taiwan's National Health Insurance (TNHI) database between 1996 and 2011 (International Classification of Diseases, Ninth Revision - Clinical Modification [ICD-9-CM] 491, 492, 496).

Alternate models of sibling status effects on health in later life.

Although siblings are thought to be influential in child development, little is known about the influence of sibling status on the health of older adults. Using structural equation modeling, the authors created and tested a series of models with data from a sample (N = 3,968) of 1957 high school graduates from the Wisconsin Longitudinal Study. The results indicated that socioeconomic status of origin, adolescent aptitude, and educational attainment did have significant total effects on health in later life, but sibling status did not.
