Personality traits and physical complaints in patients with acromegaly : a cross sectional multi-center study with analysis of influencing factors

Objective: Acromegalic patients display a distinct neuropsychological profile and suffer from chronic physical complaints. We aimed to investigate in more detail these aspects in acromegalic patients, dependent on influencing factors like disease activity, age, sex, chronic medication, surgery, pituitary radiation, pituitary insufficiency and comorbidities. Design: Cross sectional, multicentric. Methods: 129 patients (M/W 65/64, 58.3±12.7 ys., 53/76 with active/controlled disease). Acromegalic patients completed the following inventories: NEO-FFI, IIP-D, and the Giessen Complaints List (GBB-24), after written informed consent. Age, sex, IGF-1 concentrations, comorbidities, treatment modalities and pituitary insufficiency were documented. Results: Acromegalic patients or specific patient-subgroups were more agreeable, neurotic, exploitable/permissive, introverted/socially avoidant, non-assertive/insecure, nurturant and less open to experience, cold/denying, domineering, compared to normal values from the healthy population (controls). Multivariable analysis demonstrated that these overall results were due to the specific patient subgroups as patients on chronic medication, with arthrosis and pituitary insufficiency. Disease activity was only associated with the trait nurturant. Higher scores for introversion were associated with arthrosis. Lower domineering was independent of any disease- or treatment related variable or comorbidity. The GBB inventory showed overall higher scores in patients, with higher scores for exhaustion and general complaints being associated with pituitary insufficiency, coronary heart disease and history of malignancy in the multivariable analysis. Joint complaints were independent of any disease- or treatment- related variable. Conclusions: We define new aspects of a distinct neuropsychological profile in patients with acromegaly, which are largely independent of disease activity. Chronic physical complaints are more pronounced in patients than in controls, with exhaustion and general complaints showing no association with disease activity

The Yield of Radiation-Induced Micronuclei in Early and Late-Arising Binucleated Cells Depends on Radiation Quality

There are conflicting data regarding the effect of culturing time of human peripheral blood lymphocytes on the yield of chromosomal aberrations induced by sparsely ionising radiation in the G0 phase of the cell cycle. While some authors find that the yield of aberratioons does not change with time, others find increased frequencies of aberrations with harvesting time. The reasons for the conflicting results are not known, but the majority of studies were performed with lymphocytes of a single donor collected at one time point. We performed a study to verify if individual variability could be confounding factor. As a positive control, lymphocytes were also exposed to high LET radiation, where an efect of harvesting time on the level of damage is expected to be seen. Blood was drawn from a total of 8 donors at two time points and exposed to X-rays, 6 MeV neutrons or alpha particles generated by an Am-241 source. Whole blood cultures were set up and micronuclei were scored in binucleated cells harvested after 72, 96 and 120 h of culture time. The results show that in lymphocytes exposed to X-rays, the frequency of Mn was generally not influenced by the culture time while for both neutrons and alpha particles consistently increased micronucleus frequencies with culture time were detected. Some individual variability was detected and the conflicting results regarding the relationship between the yield of cytogenetic damage and lymphocyte culture time can, at least partly, be due to this variabilityJRC.F.4-Nuclear Reactor Integrity Assessment and Knowledge Managemen
