Should Sensory Impairment Be Considered in Frailty Assessment?
The inclusion of a sensory domain into a frailty screening instrument has a major impact in terms of prevalence and modifies the risk profile associated with frailty. In order to develop the use of frailty screening instruments in clinical practice, further researches will need to carefully evaluate the impact on risk prediction of the different domains involved.
The mechanism we reported for alcohol-induced intestinal barrier disruption in vitro - NO overproduction, oxidative tissue damage, leaky gut, endotoxemia, and liver injury - appears to be relevant in vivo in an animal model of alcohol-induced liver injury. That iNOS inhibitors attenuated all steps of this cascade suggests that prevention of this cascade in alcoholics will protect the liver against the injurious effects of chronic alcohol and that iNOS may be a useful target for prevention of ALD.
