Resilience, sense of coherence, purpose in life and self-transcendence in relation to perceived physical and mental health among the oldest old.

Different concepts have been presented which denote driving forces and strengths that contribute to a person's ability to meet and handle adversities, and keep or regain health. The aim of this study, which is a part of The Umeå 85+ study, was to describe resilience, sense of coherence, purpose in life and self-transcendence in relation to perceived physical and mental health in a sample of the oldest old. The study sample consisted of 125 participants 85 years of age or older, who ranked themselves on the Resilience Scale, Sense of Coherence Scale, Purpose in Life Scale and Self-Transcendence Scale and answered the SF-36 Health Survey questionnaire. The findings showed significant correlations between scores on the Resilience Scale, the Sense of Coherence Scale, the Purpose in Life Test, and the Self-Transcendence Scale. Significant correlations were also found between these scales and the SF-36 Mental Health Summary among women but not among men. There was no significant correlation between perceived physical and mental health. The mean values of the different scales showed that the oldest old have the same or higher scores than younger age groups. Regression analyses also revealed sex differences regarding mental health. The conclusions are that, the correlation between scores on the different scales suggests that the scales measure some dimension of inner strength and that the oldest old have this strength at least in the same extent as younger adults. Another conclusion is that the dimensions that constitute mental health differ between women and men.

Clostridium difficile in relation to enteric bacterial pathogens.

All feces samples (n = 2,390) sent to the Bacteriological Laboratory, Göteborg, Sweden over 43 days were, in addition to the standard procedure, cultivated to detect Clostridium difficile by using a special selective medium. C. difficile was found in 81 of the 2,390 samples (3%). These 81 samples represented 56 patients. Fifty of the 56 patients had diarrhea. In 20 of the 56 patients (36%), Salmonella, Campylobacter, or Yersinia were also found. Of the 2,390 samples 252 (11%) from 132 patients revealed positive isolations of Salmonella, Shigella, Campylobacter, or Yersinia in comparison to 3% for C. difficile alone. This result suggests that C. difficile can easily be isolated with proper techniques. Concomitant isolations of more than one bacterial pathogen in cases of gastroenteritis were often found for C. difficile. The theory presented here is that any change of the normal bacterial fecal flora due to such causes as antimicrobial treatment or enteric infections like Salmonella increases the possibilities of isolating C. difficile. The causative significance of C. difficile might in most cases be doubtful. The majority of cases with diarrhea and C. difficile were self-healing and not severe. Only 2 cases of 56 had severe diarrhea with extended engagement of the colonic mucous membrane, but with no signs of pseudomembranes.
