[Future perspectives, factors in the mental health of aged persons].

During individual interviews, 708 people between the ages of 65 and 90 expressed a wide variety of personal goals and aspirations through sentences they were asked to complete. The distribution of answers in temporal categories provides an index of the broadening of future perspectives (PF). The values of that index were put in relation with subjective assessments that can be looked upon as clues to mental health. Results confirm the hypothesis of a positive relation between PF and perception of health (0.27), meaning of life (0.29), living satisfaction (0.30) and perception of having personal control (0.18). However, PF does not appear to be connected with the person's attitude toward death. These results seem to indicate that PF represents a factor of mental health and "healthy aging". Consequently, they justify the relevance of developing interventions that aim to strengthen this "personal resource".

Sodium-phosphate cotransport and vascular reactivity.

Inorganic phosphate (PO4) alters vascular reactivity in vivo as well as in vitro. In the latter condition, low PO4 reduces, while high PO4 augments reactivity. We used phosphonoformate (PFA), a phosphaturic compound, binding the renal Na-PO4 co-transporter, to examine the existence of such a transport mechanism in selected vascular smooth muscles (VSM). Strips of aorta (A), mesenteric artery (MA), and vein (MV) were obtained from normal rabbits. All tissues were either superfused in normal PO4 (Group 1: 3 mg/dL), then in modified low PO4 (Group 2: 0 mg/dL) or high PO4 (Group 3: 9 mg/dL) Ringer's solutions. The effect of angiotensin II (AII: 10-11 to 10-8M) was tested on each tissue preparation, and contraction values obtained in the presence of PFA (18.5 micrograms/ml:0.018 ml/min) were compared to control responses in the absence of the drug. In Group 1, the contractions of A were reduced by 23% during PFA, for higher doses of AII only, compared to controls (p less than 0.01). Similarly, the contractions of MA in the presence of PFA were reduced at higher doses of AII, by 22% (p less than 0.01). Finally, the contractions of MV were reduced by 75% (p less than 0.01) for all doses of AII. In Group 2, there was no difference in vascular tissue contraction between controls and PFA, whereas in Group 3, the reduction in A, MA, and MV contractions in PFA-treated tissues were approximately twice as extensive as in Group 1 (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Motivational goal objects in later life.

With a sentence completion technique, 708 elderly participants (64 to 90 years of age) expressed 15,020 personal aspirations. These goals were classified according to their motivational content in ten major categories and their relationships with different sociodemographic variables were studied. Two goal profiles emerge from this analysis. Aspirations centered on self-preservation are associated with very old age, functional impairment, lower S.E.S. and education, being alone or institutionalized. Aspirations of self-development and interpersonal relationships are associated with younger age, physical autonomy, higher S.E.S. and education, being married or living at home. Development of meaningful personal goals are discussed as a mean of intervention with elderly individuals.
