Age-Linked Treatment Rates [PDF]
Deutsches Ärzteblatt international, 2016 Peters et al. report in their study about the management of incident breast cancer patients that patients aged >69 years received breast-conserving surgery, chemotherapy and radiotherapy significantly less frequently (1). Furthermore, even though no age-specific differences in the distribution of positive HER2/neu and hormone receptor status exist ...

Treatment of amblyopia as a function of age [PDF]
Visual Neuroscience, 2018 AbstractAlthough historically, treatment of amblyopia has been recommended prior to closure of a critical window in visual development, the existence and duration of that critical window is currently unclear. Moreover, there is clear evidence, both from animal and human studies of deprivation amblyopia, that there are different critical windows for ...

Prevention and Treatment of Skin Aging [PDF]
Annals of the New York Academy of Sciences, 2005 Abstract: Skin aging is a complex biological process that is a consequence of both intrinsic or genetically programmed aging that occurs with time, and extrinsic aging caused by environmental factors. The dramatic increase in the aging population and the psychosocial impact of skin aging has created a demand for effective interventions.
