In patients with hypothyroidism, partial substitution of triiodothyronine for thyroxine may improve mood and neuropsychological function; this finding suggests a specific effect of the triiodothyronine normally secreted by the thyroid gland.

This short version of an evidence-based guideline may improve treatment of anxiety disorders, OCD, and PTSD in primary care.

BackgroundThe relationship between Type D personality and health related quality of life (HRQoL) in coronary artery disease patients is becoming more established, however, the factors that may explain this association remain unclear. The objective of the study was to examine the mediating effects of mental distress and social support on the relationship between the Type D personality and HRQoL in CAD patients with heart failure.MethodsA total of 855 CAD patients with heart failure were assessed on Type D personality, mental distress, perceived social support and HRQoL with the following self-administered questionnaires: the Type D personality scale - 14, the Hospital Anxiety and Depression scale, the Multidimensional Scale of Perceived Social Support and the Minnesota Living with Heart Failure Questionnaire.ResultsThe prevalence of Type D personality within the study population was 33.5%. Type D personality, anxiety symptoms, depressive symptoms and social support were all found to be determinants of decreased HRQoL (p’s < 0.001), once age, gender, NYHA functional class and acute myocardial infarction were adjusted for. Anxiety, depressive symptoms and social support were found to mediate the relationship between Type D personality and HRQoL. Type D personality exerted a stable effect on HRQoL over 24 months follow-up period.ConclusionsType D personality has an independent significant effect on the HRQoL in CAD patients with heart failure, and this relation is mediated by anxiety and depressive symptoms, social support.

The highest prevalence of depressive disorders was found in the first trimester, the lowest in mid-pregnancy. Several determinants (unwanted and unplanned pregnancy, high neuroticism) were independent predictors of antenatal depressive disorders throughout whole pregnancy, while other determinants (low education, previous history of depression, the occurrence of psychosocial stressors at the end of pregnancy) were trimester specific.

Symptoms of anxiety and depression are prevalent in medical students and in humanities students. Severity of symptoms of anxiety and symptoms of depression in medical students is negatively related to emotional stability and positively related to stress vulnerability.

It was recently demonstrated that treatment with levorotatory thyroxine (T4) plus triiodothyronine (T3) compared with treatment with T4 alone improves psychologic functioning in hypothyroid patients with thyroid cancer or autoimmune thyroiditis. In the present double-blind crossover study, we again compared the effects of combined thyroid replacement vs monotherapy on psychologic function, endocrine function, cardiovascular function, and body composition. The patients were women who were hypothyroid after thyroidectomy for Graves' disease. The substitution of 10 microg of T3 for 50 microg of T4 caused a statistically significant decrease in free T4 concentration but no significant change in T3 or thyroid-stimulating hormone concentration. Symptoms of hypothyroidism and of hyperthyroidism tended to decrease on a standard symptom scale after combined treatment. With combined hormone replacement, mental state tended to improve on some mood scales but not on cognitive tests. We found alterations in left ventricular diastolic function but no change in body composition after the combined treatment regimen. These preliminary findings in a small group of patients with Graves' disease are consistent with earlier findings that thyroid replacement with T4-T3 combination improves mental functioning.

This study aimed to evaluate how precise the Edinburgh Depression Scale (EDS) is in screening for major depressive disorder (MDD) during different periods of pregnancy. A random sample of 230 pregnant women was interviewed in the first, second, and third trimesters of pregnancy using the EDS and not-patient version of the Structured Clinical Interview for DSM-III-R (SCID-NP). We evaluated test-retest reliability of the EDS; area under the ROC curve (AUC), sensitivity, specificity, and positive predictive value (PPV) of the EDS against the SCID-NP diagnoses in the first, second, and third trimesters of pregnancy. Test-retest reliability of the EDS was 0.81 (p < 0.001). An optimal cutoff score of the EDS for screening current SCID-NP diagnosis of MDD was 12 and higher in the first trimester of pregnancy (AUC 0.94, sensitivity 92%, specificity 95%, and PPV 52%) and 11 and higher in the second and third trimesters of pregnancy (AUC 0.96 and 0.90, respectively; sensitivity 100% and 88%, respectively; specificity 92% and 92%, respectively; PPV 25% and 29%, respectively). The EPDS is a reliable instrument for repeated evaluations of depressive symptoms during pregnancy. It has a good sensitivity and specificity for detecting antenatal MDD with optimal cutoff of 11/12 or higher.
