Natural aging is associated with mild memory loss and cognitive decline, and age is the greatest risk factor for neurodegenerative diseases, such as Alzheimer's disease. There is substantial evidence that oxidative stress is a major contributor to both natural aging and neurodegenerative disease, and coincidently, levels of redox active metals such as Fe and Cu are known to be elevated later in life. Recently, a pronounced age-related increase in Cu content has been reported to occur in mice and rats around a vital regulatory brain region, the subventricular zone of lateral ventricles.

Background: Observational studies have shown that selective serotonin reuptake inhibitors are associated with an increased risk of bone fractures, but the association can be confounded by indication and other sources of systematic bias that can be minimised in randomised controlled trials (RCTs).

Aim: Our aim was to report the rate, site, context, and predictors of fractures after stroke, and whether the fractures modified the effect of fluoxetine on modified Rankin score (mRS) at six months in an individual patient data meta-analysis of 5907 patients enrolled in three RCTs of fluoxetine (20mg for six months) for stroke recovery.

Methods: We classified fractures by treatment allocation, site (and thus likelihood of osteoporosis) and context, then performed multivariable analyses to explore independent predictors of fractures.

Introduction: The military employs a wide variety of training paradigms to prepare a ready medical force. Simulation-based training is prominently used in the military for all roles of care to provide the knowledge, skills, and abilities needed to render care from the battlefield to the hospital. The purpose of this scoping review is to synthesize the body of research in military healthcare simulation, highlight trends in the literature, and identify research gaps.
