Anesthesia And Frailty Risks During Post-Surgery

Frailty is a state of decreased physiologic reserve and resistance to stressors. Its prevalence increases with age and is estimated to be 26% in those aged above 85 years. As the population ages, frailty will be increasingly seen in surgical patients receiving anesthesia.

Here, they evaluate the instruments which have been developed and validated for measuring frailty in surgical patients and summarize frailty tools used in 110 studies linking frailty status with adverse outcomes post-surgery.

Disrupting Sleep At Night Cause Health Risks

That's partly to encourage customers to lose track of time. Their owners have instinctively understood long before this recent neuroscience study confirmed it that sleep-deprived people tend to take more risks. We have a wealth of knowledge from laboratory studies about what sleep loss does to mood, behavior and our ability to think and work.

We get a taste of it when we travel across time zones, work night shifts or pull all-nighters before exams. But what do we know about the real-life effects of the one hour of sleep loss that most of us experience on the same weekend each year due to daylight saving.

Treating Psoriasis Could Be Easier In Future

For approximately 8 million Americans, visiting a doctor regularly is the key to managing their psoriasis, a chronic inflammatory skin condition characterized by itchy or painful red patches that can appear anywhere on the body.

But for some people, seeing a specialist regularly can be a monumental challenge, especially for those who live in rural or underserved communities. A new study led by the Keck School of Medicine of USC, however, raises the possibility that one day, people with psoriasis may be able to simply go online to receive their care.

The study was published in JAMA Network Open, the study found that online and in-person care were equally effective at improving psoriasis symptoms.

Laboratory Grown Tissues Was More Effective

Tissues grown in the lab from stem cells may fail to live up their therapeutic promise because the cells choose their own fate. For the last 20 years, scientists have worked to engineer tissues for use in a range of conditions, such as osteoarthritis or heart failure.

Stem Cells

They do this by placing stem cells those that can become any kind of cell in biodegradable 3-D structures, or "scaffolds," in the laboratory. However, lab-grown tissues often fail to be fully effective as treatments when transplanted into patients. The study was published in the journal Nature Communications.

Lack Of Estrogen Leads To Memory Problems

Lack of estrogen may play a role in the development of anxiety and memory problems, according to a new rodent study. The findings will be presented today at the American Physiological Society's (APS) Cardiovascular, Renal and Metabolic Diseases: Sex-Specific Implications for Physiology conference in Knoxville, Tenn.
