Do physically active people cope better with biopsychosocial stress after a myocardial infarction?

A preliminary study of the relationship between a physically active versus a physically non-active life before a myocardial infarction and coping ability (e.g. psychosocial effects) after a myocardial infarction has been performed. In a mainly rural area in south-western Sweden all myocardial infarction sufferers (N = 49) during January 1984-August 1986, fulfilling certain criteria, were sent a questionnaire with special emphasis on their present and former exercise habits and psychosocial situation. The results indicate that there is a positive relation between a physically active as compared with a physically non-active life and coping ability in terms of fewer expressed depressions, better experienced relations in the family and higher degree of return to work, after a myocardial infarction among the physically active. However, further investigations are needed in order to explain the mechanisms involved. The results further imply that primary and secondary prevention must support the "risk-individual's" coping ability from a multifactorial view, built on holistic caring.

Microdialysis of adipose tissue and blood for in vivo lipolysis studies.

Glycerol levels (lipolysis index) were continuously monitored in intact rats using simultaneous microdialysis of venous blood and subcutaneous adipose tissue. Dialysis probes (0.5 X 4 mm) were implanted and perfused using a microinjection pump. The basal glycerol levels in perfusates of blood and adipose tissue were stable. Intravenous isoproterenol (isoprenaline) increased the glycerol levels in a similar fashion in blood perfusate as compared with plasma and the dialysate of two different adipose tissue probes implanted in the same animal. Isoproterenol included in the adipose tissue dialysis solvent increased the glycerol level in adipose tissue perfusate but not in the blood perfusate; this indicates a local lipolytic effect of catecholamines. Increases in intravenous doses of isoproterenol caused a transient and marked dose-dependent elevation of glycerol in the adipose tissue perfusate and a gradual but less marked rise of glycerol in blood perfusate. This indicates that glycerol kinetics in blood and adipose tissue differ after catecholamine stimulation. In conclusion, microdialysis of blood and subcutaneous adipose tissue offers new and unique possibilities for in vivo lipolysis studies in intact animals.

Five-year results with fixed complete-arch mandibular prostheses supported by 4 implants.

This study examined whether it is possible to restore an edentulous mandible with a complete-arch fixed prosthesis retained by only 4 implants without decreasing the survival rate. One hundred nineteen patients received complete-arch mandibular prostheses retained by 4 implants. Most patients were followed for 3 years or more. All patients followed a routine protocol, including annual check-ups and regular radiographic examinations. Twenty-one patients dropped out. Radiographic measurements used the threads of the implants as a basis for comparison. No indication was found that the number of supporting implants could have influenced the observed frequency of technical and surgical complications. Three implants were lost, 2 after 1 year and 1 after 5 years. A statistically significant difference in bone loss between the mesial and distal implants was found. The number of fractured resin teeth in mandibular prostheses was higher when patients had an implant-supported prosthesis in the maxilla. The present study revealed an implant survival rate of 98.6% after 5 years. Therefore, it was concluded that there may not be a need for more than 4 implants to support a fixed mandibular prosthesis, when implants at least 10 mm long can be used.
