Gender differences in anxiety and depressive symptoms in patients with primary hyperaldosteronism: A cross-sectional study

Objective. The renin-angiotensin-aldosterone-system (RAAS) has gained increasing attention in the investigation of the pathogenesis of depression. Primary hyperaldosteronism (PA) is associated with a marked aldosterone excess. Prior studies on PA describe an increased prevalence of anxiety and sub-threshold depressive symptoms in these patients. Methods. In a cross-sectional exploratory study we investigated 132 patients with PA. Twenty-seven patients were studied before initiation of specific treatment (U = untreated), 56 were studied 5.4 years after initiation of mineralocorticoid antagonist treatment (MRA) and 49 patients were studied 4.3 years after unilateral adrenalectomy (ADX). GAD-7 and PHQD self-rating questionnaires were used to assess symptoms for anxiety and depression. Results. No significant difference was found between the three investigated groups. A higher prevalence for depression and anxiety compared to the normal population was found. Women of all groups had higher mean values compared to men, for depression in untreated patients this difference was found to be significant. Correlations between the psychopathology and hormones were only found for renin. Plasma renin concentration correlated significantly with anxious symptoms of untreated females. Conclusions. This study supports the RAAS to be involved in the pathogenesis of depression as patients with PA seem to be more depressive and anxious compared to the normal population. Gender differences in the regulation of the RAAS seem to be apparent, as females were more affected by the dysregulation than males.     

Cognitive Behavioral Therapy for Depressed Adults With Mild Intellectual Disability: A Pilot Study

There is a paucity of research on psychosocial treatments for depression in adults with intellectual disability (ID). In this pilot study, we explored the efficacy of a group CBT treatment that involved a caregiver component in adults with mild ID with a depressive disorder. Sixteen adults with mild ID and a depressive disorder participated in a 10-week group CBT treatment and eight adults with mild ID with a depressive disorder served as a treatment as usual (TAU) control group. Adults with mild ID and caregivers completed measures of depressive symptoms, behavior problems, and social skills at pretreatment, posttreatment, and a 3-month follow-up. Adults with mild ID also completed a series of tasks to measure their understanding of the principles of cognitive therapy pre- and posttreatment. The CBT group demonstrated significant decreases in depressive symptoms and behavior problems from pretreatment to posttreatment and these effects were maintained at a 3-month follow-up. The CBT group demonstrated significant improvements in their ability to infer emotions and thoughts based on various situation-thought-emotion pairings from pretreatment to posttreatment. Findings indicate that adults with mild ID with a depressive disorder benefitted from a group CBT treatment with a caregiver component. Moreover, adults with mild ID appeared to benefit, at least in part, from the cognitive therapy components of the treatment, in addition to the behavior therapy components.     

Self-referential processing influences functional activation during cognitive control: an fMRI study

Rostral anterior cingulate cortex (rACC) plays a central role in the pathophysiology of major depressive disorder (MDD). As we reported in our previous study (Wagner et al., 2006), patients with MDD were characterized by an inability to deactivate this region during cognitive processing leading to a compensatory prefrontal hyperactivation. This hyperactivation in rACC may be related to a deficient inhibitory control of negative self-referential processes, which in turn may interfere with cognitive control task execution and the underlying fronto-cingulate network activation. To test this assumption, a functional magnetic resonance imaging study was conducted in 34 healthy subjects. Univariate and functional connectivity analyses in statistical parametric mapping software 8 were used. Self-referential stimuli and the Stroop task were presented in an event-related design. As hypothesized, rACC was specifically engaged during negative self-referential processing (SRP) and was significantly related to the degree of depressive symptoms in participants. BOLD signal in rACC showed increased valence-dependent (negative vs neutral SRP) interaction with BOLD signal in prefrontal and dorsal anterior cingulate regions during Stroop task performance. This result provides strong support for the notion that enhanced rACC interacts with brain regions involved in cognitive control processes and substantiates our previous interpretation of increased rACC and prefrontal activation in patients during Stroop task.     

Application of depression criteria (DSM-IV) in patients with Parkinson's disease

Introduction

The aim of this study is to analyze the clinical differences between Parkinson's disease patients with major (MD) and minor depression (md) and to see how both affect the quality of life.

Material and methods

118 patients diagnosed with Parkinson's disease. The mean age of onset was 60.4 ± 11.2 years with a mean duration of 8.5 ± 6.2 years. Depression was diagnosed according to DSM-IV-TR criteria. Scores on the Hamilton depression inventory, MMSE, PDQ-39, NPI-10, UPDRS III, and UPDRS IV were recorded.

Results

Twenty-one patients (17.8%) met the criteria of major depression (MD) and 33 (28.0%) those of minor depression (md). The scores on the PDQ-39 and NPI-10 of patients with MD were higher than in patients with md, and control group. The MMSE scores were lower in patients with MD. In 52.2% of the patients with MD, the diagnosis of depression was made prior to that of PD, this occurred only in 24.2% of the patients with md (p < 0.001). The presence of anhedonia was related to cognitive impairment and the presence of neuropsychiatric symptoms.

Discussion

MD is probably a part of the disease process of PD; it is associated with cognitive impairment and may precede motor symptoms.     

Implementation of Guideline-Based Care for Depression in Primary Care

Evidence-based clinical practice guidelines for treating depression in primary care settings were developed, in part, to ensure that health services are provided in a consistent, high-quality, and cost-effective manner. Yet for a variety of reasons, guideline-based primary care for depression remains the exception rather than the rule. This work provides a brief review of effective strategies used to customize and then deliver evidence-based treatment for depression in primary care settings; describes two representative case studies that illustrate locally customized collaborative care strategies for treatment delivery; and concludes with principles and implications for policy and practice based on our practical experiences.     

Challenges of Implementing Depression Care Management in the Primary Care Setting

Empirical evidence shows that care management is an effective tool for improving depression treatment in primary care patients. However, several conceptual and practical issues have not been sufficiently addressed. This article explores questions concerning the scope of care management services within the chronic illness care model; optimal ways to identify depressed patients in the primary care setting; responsibilities and desirable qualifications of depression care managers; the location and manner in which care managers interact with patients; costs of services provided by care managers; and the level of supervision by mental health specialists that is necessary to ensure quality care.     

卒中后抑郁患者的交感神经皮肤反应与事件相关电位对照研究

目的探讨交感神经皮肤反应(SSR)与事件相关电位(ERP)对卒中后抑郁患者的诊断价值。方法对55例卒中后抑郁患者和52例正常健康者分别进行了SSR和ERP测定,并将结果加以比较。结果卒中后抑郁组中SSR和ERP测定中的P300成分异常率分别为87.3%(48/55)和83.6%(46/55),两者异常吻合率为76.4%(42/55)。卒中后抑郁组SSR测定结果中,SSR潜伏期和波幅值较对照组延长和降低,其差异具有显著性(P<0.01),ERP测定中N2、P3波潜伏期和P3波幅较对照组分别延长和降低,存在显著性差异(P<0.01)。其中N2、P3波潜伏期与SSR测定中潜伏期以及波幅与波幅之间呈正相关(r=0.29~0.36,P<0.01),而两者潜伏期与波幅之间呈负相关(r=-0.32~-0.33,P<0.01)。结论交感神经皮肤反应和事件相关电位测定可作为卒中后抑郁患者的诊断指标应用于临床。     

抑郁症患者的血糖、血脂水平及其与症状关系的对照研究

目的了解抑郁症患者糖脂代谢的情况及其与精神症状的关系。方法以HAMD17和HAMA评定92例近期未服用精神药物的抑郁症患者的精神症状,了解他们简易体质参数、测定其空腹血糖和血脂,并与60例健康者组成的对照组进行比较。结果抑郁症组的甘油三酯(TG)、空腹血糖(FBS)值显著高于对照组(P＜0．001),而高密度脂蛋白胆固醇(LDL—ch)、载脂蛋白A1(ApoA1)值显著低于对照组(P＜0．01);血浆总胆固醇(TC)、高密度脂蛋白胆固醇(HDL—ch)和载脂蛋白B(ApoB)两组之间无显著性差异(P＞0．05);相关分析发现,抑郁症患者的HAMA总分、精神性焦虑因子分以及躯体性焦虑因子分与TG水平呈正相关(P＜0．01或P＜0．05)。结论抑郁症患者存在一定的糖脂代谢异常,临床医师应该对抑郁症患者的血糖、血脂进行监测,以便早期发现,早期治疗。
