ObjectiveThis study explored whether young adults with major depression who are physically active differ in their depression symptom profile from those physically inactive.MethodsAnalyses included data from 950 (47.6%) men and 1045 women (mean [standard deviation] age = 31.5 [2.6] years) participating in a national study. Participants reported leisure physical activity (International Physical Activity Questionnaire) and ambulatory activity (pedometer steps per day). Diagnosis and symptoms of major depression were assessed using the Composite International Diagnostic Interview.ResultsPrevalence of major depression was 5.5% (n = 52) for men and 11.6% (n = 121) for women. Interactions between physical activity and sex were observed for depressed mood, appetite changes, vacillating thoughts, and suicidality (all, p < .050). Among those with major depression, physically active men were significantly less likely to endorse the presence of insomnia (prevalence ratio [PR] = 0.78, 95% confidence interval [CI] = 0.63-0.96), fatigue (PR = 0.82, 95% CI = 0.69-0.99), and suicidality (PR = 0.69, 95% CI = 0.49-0.96) compared with inactive men. Physically active women were significantly less likely to endorse hypersomnia (PR = 0.50, 95% CI = 0.27-0.95), excessive/irrational guilt (PR = 0.76, 95% CI = 0.59-0.97), vacillating thoughts (PR = 0.74, 95% CI = 0.58-0.95), and suicidality (PR = 0.43, 95% CI = 0.20-0.89) compared with inactive women. Associations were adjusted for age, physical health, educational attainment, depression severity, and other depressive symptoms.ConclusionsAmong adults with major depression, those physically active seem to differ in their depression symptom profile from those physically inactive.

ObjectiveCross-sectional studies suggest a strong association between depression and restless legs syndrome (RLS); however, the temporal relationship between the two disorders remains unknown. We tested whether the presence of clinically relevant depressive symptoms (CRDS) is a risk factor for subsequent RLS in the general population. The relationship between prevalent RLS and incident CRDS was also examined.MethodsTwo independent, prospective cohort studies with representative, age-stratified random samples, the Dortmund Health Study (DHS; n = 1312/1122 [baseline/follow-up], median follow-up time = 2.1 years) and the Study of Health in Pomerania (SHIP; n = 4308/3300, median follow-up time = 5.0 years) were analyzed. RLS was assessed in both studies according to the RLS minimal criteria, at baseline and at follow-up. CRDS were assessed by the Center for Epidemiologic Studies-Depression scale (a score of ?16) in DHS only at baseline and by the Munich-Composite International Diagnostic-Screener in SHIP at baseline and at follow-up.ResultsClinically relevant depressive symptoms at baseline were associated new-onset RLS in both studies (DHS: odds ratio [OR] = 1.94, 95% confidence interval [CI] = 1.09-3.44; SHIP: OR = 2.37, 95% CI = 1.65-3.40) after adjustment for age, sex, education, body mass index, smoking, physical activity, and the presence of various comorbidities. RLS at baseline was an independent risk factor of incident CRDS in SHIP (OR = 1.82, 95% CI = 1.10-3.00).ConclusionsThe presence of CRDS may be a risk factor for subsequent RLS. The relationship between the two disorders might be bidirectional because RLS also predicts incident depressive symptoms. HubMed – depression

ObjectiveThis study compares sensory-biological, cognitive-emotional, and cognitive-interpretational factors in predicting angina on an exercise treadmill test (ETT).MethodsA total of 163 patients with ETT-induced ischemia and coronary artery disease in the National Heart, Lung, and Blood Institute Psychophysiological Investigations of Myocardial Ischemia study were given an ETT, during which 79 patients reported angina. We assessed the following as potential predictors of self-reported anginal pain: sensory-biological factors (?-endorphin reactivity, hot pain threshold, and maximal ST-segment depression), cognitive-emotional factors (negative affect and symptom perception), and cognitive-interpretational factors (self-reported history of exercise-induced angina). Models were covariate adjusted with predictors examined individually and as part of component blocks.ResultsLogistic regression revealed that history of angina (odds ratio [OR] = 17.41, 95% confidence interval = 7.16-42.34) and negative affect (OR = 1.65, 95% confidence interval = 1.17-2.34), but not maximal ST-segment depression, hot pain threshold, ?-endorphin reactivity, or symptom perception, were significant predictors of angina on the ETT. The sensory-biological block was not significantly predictive of anginal pain (?(2)block = 5.15, p = .741). However, the cognitive-emotional block (?(2)block = 11.19, p = .004) and history of angina (cognitive-interpretation; ?(2)block = 54.87, p < .001) were predictive of ETT angina. A model including all variables revealed that only history of angina was predictive of ETT pain (OR = 16.39, p < .001), although negative affect approached significance (OR = 1.45, p = .07).ConclusionsIn patients with ischemia, cognitive-emotional and cognitive-interpretational factors are important predictors of exercise angina.

OBJECTIVE: The aim of this study was to examine interest in psychosocial interventions among patients with multiple myeloma at time of diagnosis as well as associated factors. METHODS: Patients with newly diagnosed multiple myeloma were recruited from our outpatient myeloma unit at the Heidelberg University Hospital. Patients completed questionnaires that included a checklist on desired psychosocial interventions and the Patient Health Questionnaire 9-item (PHQ-9) depression and Generalized Anxiety Disorder 7-item scale (GAD-7) anxiety scales. Medical data were extracted from the patients’ electronic records. RESULTS: The survey was completed by 114 out of the 130 myeloma patients. Half of the patients (51%) desired psychosocial interventions. The most common preferences were relaxation techniques (21%), psychological counseling (20%), and peer support groups (18%). Approximately 24% of the patients reported symptoms of depression, and 8% reported symptoms of anxiety. Patients with symptoms of depression had twice as many preferences for psychosocial interventions as nondepressed patients. They more frequently desired individual psychotherapy (p?=?0.035) and peer support groups (p?=?0.015). In general, lower age was associated with greater interest in psychosocial interventions. Medical status was not strongly associated with interest in psychosocial interventions. CONCLUSIONS: A high percentage (51%) of patients with multiple myeloma has psychosocial intervention desires at the time of diagnosis. The greatest interest was found in depressed and younger patients. However, depressed patients do not prefer a single intervention form but rather show a broad variability of wishes, so ‘one size does not fit all’. Therefore, to reach all patients in need, a choice of psychosocial interventions should be offered. Copyright © 2013 John Wiley & Sons, Ltd. HubMed – depression


Role of SAP97 in the regulation of corticotropin-releasing factor receptor 1 endocytosis and ERK1/2 signaling.

The corticotropin-releasing factor (CRF) receptor 1 (CRFR1) is a target for the treatment of psychiatric diseases such as depression, schizophrenia, anxiety disorder, and bipolar disorder. The carboxyl-terminal tail of the CRFR1 terminates in a PDZ binding motif that provides a potential site for the interaction of PSD-95/Discs Large/Zona Occludens 1 (PDZ) domain containing proteins. In the present study, we found that CRFR1 interacts with synapse-associated protein 97 (SAP97; also known as DLG1) by co-immunoprecipitation in human embryonic 293 (HEK 293) cells and cortical brain lysates and that this interaction is dependent upon an intact PDZ binding motif at the end of the CRFR1 carboxyl-terminal tail. Similarly, we demonstrated that SAP97 is recruited to the plasma membrane in HEK 293 cells expressing CRFR1 and that mutation of the CRFR1 PDZ binding motif results in the redistribution of SAP97 into the cytoplasm. Overexpression of SAP97 antagonized agonist-stimulated CRFR1 internalization, whereas single hairpin (shRNA) knockdown of endogenous SAP97 in HEK 293 cells resulted in increased agonist-stimulated CRFR1 endocytosis. CRFR1 was internalized as a complex with SAP97 resulting in the redistribution of SAP97 to endocytic vesicles. Overexpression or shRNA knockdown of SAP97 did not significantly affect CRFR1-mediated cAMP formation but SAP97 knockdown did significantly attenuate CRFR1-stimulated ERK1/2 phosphorylation in a PDZ interaction-independent manner. Taken together, our studies show that SAP97 interactions with CRFR1 attenuate CRFR1 endocytosis and that SAP97 is involved in coupling GPCRs to the activation of the ERK1/2 signaling pathway.
