Preoperative frailty assessment combined with prehabilitation and nutrition strategies: Emerging concepts and clinical outcomes.

Important elements of the preoperative assessment that should be addressed for the older adult population include frailty, comorbidities, nutritional status, cognition, and medications. Frailty has emerged as a plausible predictor of adverse outcomes after surgery. It is present in older patients and is characterized by multisystem physiologic decline, increased vulnerability to stressors, and adverse clinical outcomes.

Reliability of estimates of return of lost letters as a measure of public attitudes to taking human life.

An analysis of letters distributed in cities and smaller rural communities in north and south Florida (ns=400 and 448) showed return rates among several addressees were slightly but significantly correlated (rs=.10 and .10) so very small interpoll agreement is present.

Extensions of the lost letter technique to divisive issues of creationism, darwinism, sex education, and gay and lesbian affiliations.

Two field studies using 1,004 "lost letters" were designed to test the hypotheses that returned responses would be greater in small towns than from a city, that addressees' affiliation with a group either (1) opposed to physical education in schools, (2) supporting gay and lesbian teachers, or (3) advocating Creationism or Darwinism would reduce the return rate. Of 504 letters "lost" in Study A, 163 (32.3%) were returned in the mail from residents of southeast Louisiana and indicated across 3 addressees and 2 sizes of community, addressees' affiLiations were not associated with returned responses.
