Serum ferritin in type I diabetes.

The concentration and degree of glycosylation of serum ferritin was evaluated in type I male diabetic patients at different levels of glycaemic control. Serum ferritin did not appear to be affected by hyperglycaemia, but some patients undergoing photocoagulation had abnormally high levels of serum ferritin. The glycosylated, (concanavalin A binding), proportion of serum ferritin was essentially the same in the control and diabetic groups. The finding that hyperglycaemia does not affect the degree of enzymatic glycosylation of this serum protein is discussed.

[Anxiety-generating stress].

After a definition of the condition and a discussion of its physiopathological significance, the need to examine the patient as a whole and provide total therapy is emphasised with reference to both the literature and personal cases. It is concluded: 1) that the mesodiencephalic structures, especially the hypothalamus, are of primary importance in human physiological and pathological processes. The hypothalamus is the real brain of the viscera, the functional bridge between the hypophysis, the limbic structures and the upper cortical centres; 2) that doctors should consider the role of the hypothalamus in the diagnosis and therapy of the total person: a) in evaluating the patient's real emotional and psychological situation; b) in realising that the simple administration of a drug to cure the organic symptom really means only partial treatment of the patient himself.

Self-monitoring and blood pressure.

The association between self-monitoring (regulation and control of nonverbal and expressive behavior) and blood pressure was examined in a field study of 594 municipal employees. For persons not taking antihypertensive medication, the Acting/Extraversion scale was mildly positively associated with resting blood pressure among whites in general, blue collar, clerical, and professional groups. Stronger positive correlations were obtained for attorneys and customer service representatives. These results are contrasted with slightly negative associations for blacks in general, first-level supervisors, and a group of previously studied union stewards. An interactive effect was also obtained between Acting/Extraversion and relative participation in work versus nonwork groups and activities; Acting/Extraversion and systolic pressure were inversely related for employees more active in extrawork groups but not related among other workers. Differential consequences of greater or lesser interpersonal involvement and emotional regulation in different jobs are considered.

Blood pressure of male municipal employees: effects of job status and worksite.

Repeated measurements of resting blood pressure and heart rate were obtained at the worksite for a sample of 441 male municipal employees ranging widely in age (M = 41 yr.), job level, and education. As a result of unusually high diastolic values (M = 91), over-all uncontrolled hypertension rates were very high (33% of the men exceeding 160 systolic or 95 diastolic including those on medication). Higher rates were obtained for blue collar as opposed to white collar employees and for those plant workers in the Division of Water as opposed to Sewerage and Drainage. Net of age, weight, smoking, education, and anti-hypertensive medication use, higher systolic and diastolic mean values were obtained for supervisors who were primarily employed as foremen and clerical personnel. Inter-plant differences in blood pressure were also found for primarily blue collar Sewers and Drains employees, though whites' and blacks' values were nearly identical. Comparisons with national blood pressure data indicate significant effects for level of job and education which again disfavored supervisors and clerical employees and in addition men who had more education. Whites' and blacks' blood pressures deviated significantly from expected values, the differences favoring blacks. Social psychological mechanisms which may mediate these effects are discussed.

Psychological correlates of blood pressure: a closer examination of hostility, anxiety, and engagement.

Recent studies by other investigators have shown that hypertensives are more hostile and anxious than normotensives. The first part of this study examined the relationship between blood pressure measured daily over a one-week period and responses to a series of questions specifically developed to distinguish hypertensives from normotensives. Responses from this sample of undergraduates did not distinguish those with high blood pressure from those with normal values. Mean resting blood pressure was related to hostility and anxiety factor scores among males but not among females. Our second study used a sample of municipal employees and examined blood pressure as a function of comparable anxiety and hostility scores as well as a trait measure of overall "engagement-involvement." More highly engaged workers were no different in anxiety or hostility than less engaged workers. There was some evidence of more variable blood pressure for the former group. It is suggested that stable personality traits such as hostility and anxiety may both precede and follow the diagnosis of blood pressure. For nurses it is important to assess the patient's general psychological profile as well as his of her emotional state at the time of measurement. Repeated blood pressure readings are recommended especially for highly engaged individuals.
