Smokers ages 50+: who gets physician advice to quit?

BACKGROUND: Smoking-related morbidity and mortality, and benefits associated with quitting, extend across the life span. Health care provider interventions enhance quitting. The present study examined perceived influence of physician advice to quit and characteristics of subjects receiving this advice. METHODS: Subjects were 1,454 smokers ages 50+ with at least one physician visit in the past year. Subjects were surveyed at baseline for receipt of and reactions to physician advice to quit and for smoking, health, and demographic characteristics. RESULTS: Over half of subjects welcomed physician advice to quit, about half said the advice influenced their quitting decision "extremely" or "quite a lot," and about one-third indicated that it increased their confidence in quitting. Physicians were more likely to advise sicker patients, indicated by poorer health status, at least one past year hospitalization, and presence of cardiovascular, cerebrovascular, or respiratory diseases. CONCLUSIONS: Midlife and older smokers reacted generally favorably to physician advice to quit. Physicians were more likely to advise patients with commonly recognized smoking-related diseases. Discrepancies were noted in advice given to sicker vs healthier patients. Additional physician training in less commonly recognized smoking-related illnesses, intervening with healthier patients to prevent disease, and enhancing patients' confidence in quitting may improve outcomes.

The effects of chronic effusion on knee joint proprioception: a case study.

Knee joint effusion has been shown to cause a reflex inhibition of the quadriceps musculature. However, the effect of effusion on knee joint proprioception has not been thoroughly investigated. This issue is further clouded by the debate surrounding the role of the muscle spindle and joint mechanoreceptors in providing afferent feedback to the central nervous system. This case study examines the effects of a chronic effusion on knee joint proprioception. Possible suggestions for the results are discussed, and areas for further study are offered.

The elderly patient and informed consent. Empirical findings.

Informed consent with the elderly patient and the competency of this patient population have been neglected issues in medicine and law. Particularly, the competency of the elderly patient has received little empirical investigation. The present study examines the capacity of geriatric patients to consent to research participation. Competency is investigated through the use of hypothetical consent information on three dimensions: comprehension of consent material, quality of reasoning about the decision to participate or not participate in research, and reasonable choice regarding participation. The results indicate that elderly patients' choices about those projects in which participation is "reasonable" do not differ, by and large, from younger patients. However, the elderly show significantly poorer comprehension of consent information. Thus, screening for competency and providing special instructions may become an important part of the research process when the elderly are participants.

Adverse effects of single therapeutic doses of diazepam on performance in normal geriatric subjects: relationship to plasma concentrations.

Elderly normal volunteers (N = 12, mean age 70.4 years) were administered placebo or diazepam 2.5, 5, 10 mg in four consecutive sessions separated by at least a 1-week interval. Memory and psychomotor performance and plasma diazepam concentrations were assessed at baseline and at 1 and 3 h following drug administration. Significant impairments were found in response to all doses of diazepam. The maximum impairment occurred at 1 h, which coincided with the highest plasma concentration of the drug.
