Show moreUnderstanding maternal mental health and cortisol regulation across pregnancy and the relationship to the development of the offspring's stress regulation Is critical to a range of health outcomes. The aim of this study was to investigate infant and maternal cortisol in women with depression. Data were obtained from 241 pregnant women within the Mercy Pregnancy and Emotional Wellbeing Study (MPEWS), a selected pregnancy cohort study. Depression was measured using the Structured Clinical Interview for DSM-IV (SCID-IV) and repeat Edinburgh Postnatal Depression Scale (EPDS). Repeated measures of antidepressant use, stressful events, anxiety symptoms and maternal hair cortisol concentrations (HCC) and infant cortisol at 12 months postpartum in saliva and hair. Socio-emotional outcomes were measured at 12 months by maternal report on the Brief Infant and Toddler Socio-emotional Assessment (BITSEA). This study found that maternal depression was not associated with maternal HCC. Anxiety, stress and antidepressant use were not associated with maternal HCC. Independently, higher maternal 3rd trimester maternal depressive and anxiety symptoms were associated with lower infant cortisol response at 12 months of age. A higher number of postpartum stressful events was associated with lower infant cortisol response. Lower infant stress reactivity was associated with higher externalizing symptoms at 12 months of age. Future studies are required to understand implications for later mental health. Show less

Show moreAim: To identify moderators of treatment effect for Mindfulness-Based Cognitive Therapy (MBCT) versus Treatment As Usual (TAU) in depressed patients.Methods: An individual patient data-analysis was performed on three randomized-controlled trials, investigating the effect of MBCT + TAU versus TAU alone (N = 292). Patients were either in (partial) remission, currently depressed or had chronic, treatment-resistant depression. Outcomes were depressive symptoms and quality of life. The Qualitative INteraction Trees (QUINT) method was used to identify subgroups that benefited more from either condition.Results: MBCT + TAU outperformed TAU in reducing depressive symptoms. For both conditions, the effect of baseline depressive symptoms on post-treatment depressive symptoms was curvilinear. QUINT analyses revealed that MBCT + TAU was more beneficial than TAU for patients with an earlier onset and higher rumination levels in terms of depressive symptom reduction and for patients with a lower quality of life in terms of improving quality of life.Conclusions: The results suggest that MBCT might be more beneficial for those with earlier onset and higher levels of rumination and for patients with a lower quality of life. Sophisticated analytical techniques such as QUINT can be used in future research to improve personalized assignment of MBCT to patients. Long-term outcome could also be integrated in this. Show less

Show moreIntroduction: It has been suggested that the development of post-stroke apathy (PSA) and depression (PSD) may be more strongly associated with generalised brain pathology, rather than the stroke lesion itself. The present study aimed to investigate associations between imaging markers of lesion-related and generalised brain pathology and the development of PSA and PSD during a one-year follow-up.Patients and methods: In a prospective cohort study, 188 stroke patients received 3-Tesla MRI at baseline (three months post-stroke) for evaluation of lesion-related, vascular, and degenerative brain pathology. Presence of lacunes, microbleeds, white matter hyperintensities, and enlarged perivascular spaces was summed to provide a measure of total cerebral small vessel disease (cSVD) burden (range 0-4). The Mini International Neuropsychiatric Interview and Apathy Evaluation Scale were administered at baseline and repeated at 6- and 12-month follow-up to define presence of PSD and PSA, respectively.Results: Population-averaged logistic regression models showed that global brain atrophy and severe cSVD burden (score 3-4) were significantly associated with the odds of having PSA (ORGEE 5.33, 95% CI 1.99-14.25 and 3.04, 95% CI 1.20-7.69, respectively), independent of stroke lesion volume and co-morbid PSD. Medium cSVD burden (score 2) was significantly associated with the odds of having PSD (ORGEE 2.92, 95% CI 1.09-7.78), independent of stroke lesion volume, co-morbid PSA, and pre-stroke depression. No associations were found with lesion-related markers.Conclusions: The results suggest that generalised degenerative and vascular brain pathology, rather than lesion-related pathology, is an important predictor for the development of PSA, and less strongly for PSD.

Show moreBackground Studies show mixed results on the association between depressive symptoms and adverse clinical outcomes in patients on dialysis therapy. Ethnicity may play a role in these heterogeneous results. No studies have investigated the interplay between ethnicity and depressive symptoms on clinical outcome in this patient population. This study aims to examine interaction between ethnicity and depressive symptoms on hospitalization and mortality in dialysis patients. Methods A multi-ethnic cohort in 10 dialysis centers included 687 dialysis patients between 2012 and 2017, with an average follow-up of 3.2 years. Depressive symptoms were measured using the Beck Depression Inventory. Interaction was assessed by investigating excess risk on an additive scale using both absolute rates and relative risks. Multivariable regression models included demographic, social, and clinical variables. Results Adverse outcomes are more pronounced in native patients, compared to immigrant patients. The risk for mortality and hospitalization is considerably higher in native patients compared to immigrants. An excess risk on an additive scale indicates the presence of possible causal interaction. Conclusions Depressive symptoms are a risk factor for hospitalization and mortality, especially in native dialysis patients. Adverse clinical events associated with depressive symptoms differ among ethnic groups. This differential association could play a role in the conflicting findings in literature. Ethnicity is an important factor when investigating depressive symptoms and clinical outcome in dialysis patients. Future research should focus on the possible mechanisms and pathways involved in these differential associations. Show less

Show morePsychomotor symptoms are core features of melancholic depression. This study investigates whether psychomotor disturbance predicts the outcome of electroconvulsive therapy (ECT) and how the treatment modulates psychomotor disturbance. In 73 adults suffering from major depressive disorder psychomotor functioning was evaluated before, during and after ECT using the observer-rated CORE measure and objective measures including accelerometry and a drawing task. Regression models were fitted to assess the predictive value of melancholic depression (CORE >= 8) and the psychomotor variables on ECT outcome, while effects on psychomotor functioning were evaluated through linear mixed models. Patients with CORE-defined melancholic depression (n = 41) had a 4.9 times greater chance of reaching response than those (n = 24) with non-melancholic depression (Chi-Square = 7.5, P = 0.006). At baseline, both higher total CORE scores (AUC = 0.76; P = 0.001) and needing more cognitive (AUC = 0.78; P = 0.001) and motor time (AUC = 0.76; P = 0.003) on the drawing task corresponded to superior ECT outcomes, as did lower daytime activity levels (AUC = 0.76) although not significantly so after Bonferroni correction for multiple testing. A greater CORE-score reduction in the first week of ECT was associated with higher ECT effectiveness. ECT reduced CORE-assessed psychomotor symptoms and improved activity levels only in those patients showing the severer baseline retardation. Although the sample was relatively small, psychomotor symptoms were clearly associated with beneficial outcome of ECT in patients with major depression, indicating that monitoring psychomotor deficits can help personalise treatment.

Show moreBackground: Metabolic syndrome (MetS) has been associated with both early- and late-life depression. This study investigated whether baseline MetS and its individual components are associated with the course of depression over six years among older persons with a formal depression diagnosis.Methods: Data were used from 378 older persons with a depressive disorder from the Netherlands Study of Depression in Old age (NESDO) with a 6-year follow-up. A formal depression diagnosis according to DSM-IV-TR criteria was ascertained with the Composite International Diagnostic Interview. Severity of depressive symptoms was assessed with the Inventory of Depressive Symptomatology at 6-month intervals. Metabolic syndrome (MetS) was defined according the modified National Cholesterol Education Programme - Adult Treatment Panel III criteria. Primary outcome was time to remission from depression. We applied cox regression analysis for the primary outcome and linear mixed models for secondary analyses.Results: Neither MetS nor its individual components were associated with time to remission from depression (MetS: HR = 1.03; 95% CI = 0.74 - 1.44; p = 0.85), or with depression severity (MetS: B = 0.02; SE = 0.04; p = 0.64) and course of depressive symptoms (MetS: B = -0.01; SE = 0.01; p = 0.23) over 6-years follow-up.Limitations: Attrition was relatively high (46.8%). Furthermore, we only had information on formal depression diagnosis at baseline, 2-year, and 6-year follow-up.Conclusions: We found no evidence for an effect of baseline presence of metabolic dysregulation on the course of formally diagnosed depression in older persons. Metabolic syndrome in depressed patients should be clinically monitored for other reasons than predicting chronicity or severity of depression. Show less

Show moreBackground and objectives: Comorbidity among anxiety and depression disorders and their symptoms is high. Rumination and worry have been found to mediate prospective cross-disorder relations between anxiety and depression disorders and their symptoms in adolescents and adults. We examined whether generic repetitive negative thinking (RNT), that is content- and disorder-independent, also mediates prospective cross-disorder associations between anxiety and depressions disorders and their symptoms.Methods: This was studied using a 5-year prospective cohort study. In a mixed sample of 1859 adults (persons with a prior history of or a current affective disorder and healthy individuals), we assessed DSM-IV affective disorders (Composite Interview Diagnostic Instrument), anxiety (Beck Anxiety Inventory) and depression symptoms (Inventory of Depressive Symptomatology) and RNT (Perseverative Thinking Questionnaire).Results: We found that baseline depression disorders and symptom severity have predictive value for anxiety disorders and symptom severity five years later (and vice versa) and that these associations were significantly mediated by level of RNT as assessed two years after baseline. The significant and rather large mediation effects seemed mainly due to the mental capacity captured by RNT, especially in the prospective relation of anxiety with future depression.Limitations: The mediation effects were greatly attenuated or even nullified after rigorously controlling for concomitant psychopathology at two years after baseline.Conclusions: From these results it can be concluded that repetitive negative thinking could be an important transdiagnostic factor, that may constitute a suitable target for treatment.

Show moreThe forced swim test (FST) for rodents does not model despair or helplessness. It also is not a read-out for depression, anxiety, psychomotor retardation or autism, because these are anthropomorphic interpretations of the rodent's acquired immobility. Rather, the transition from swimming to immobility allows to examine the mechanistic underpinning of coping with inescapable stressors. However, in a recent detailed analysis of the FST application over the past 40 years, we noted a dramatic surge in the use of this test to phenotype animals as 'depressed'. As a follow up to that report, we now present an analysis of the use of the FST over the past three years. This literature analysis shows that the popularity of the EST is still increasing and that the majority of researchers qualifies the rodent's floating response as depressive-like behavior. However, over the past few years we also note a trend to interpret immobility rather as the expression of a coping strategy. In view of this result, we have sent a poll to the relevant authors to learn how consistent they are in naming FST behavior. Remarkably, we find a dramatic inverse correlation between their first qualification of acquired immobility as depressive-like behavior towards their current interpretation as coping strategy. In this contribution we have embedded our literature analysis and poll results in an update on the management of coping with inescapable stressors by processing in prefrontal cortical circuitry and glucocorticoid feedback.

Show moreThe gender difference in the prevalence of depression is well-documented, poorly understood and multifactorial. Considering that gender differences exist in the expression of emotions, we hypothesized that ambivalence over the expression of sadness and anger contributes to the difference in depression scores between men and women. Questionnaires on depressive symptoms and ambivalence regarding sadness and anger expression were completed by 550 respondents (66.9% women, average age 27.8years). Women reported more depressive symptoms and were more ambivalent over the expression of both sadness and anger than men. Ambivalence over sadness andto a lesser extentanger mediated the relationship between gender and depressive symptoms. We conclude that ambivalence over emotion expression may partly explain why depression occurs more frequently in women than men. Show less

Show moreObjective: The aim of this study was to evaluate the cost-utility of a guided Internet-based intervention for people living with HIV and depressive symptoms, compared to attention only (control condition). It was previously found that the intervention was effective in decreasing depressive symptoms, compared to the control group.Methods: This economic evaluation was conducted alongside a randomized controlled trial. The control group received attention only and was put on a waiting list. Quality adjusted life years were calculated over six months. The study was conducted from a societal perspective and included intervention costs, healthcare costs, and non healthcare costs. Participants completed a pretest, a post-test after two to three months, and a second post-test after six months. Cost-utility acceptability curves were constructed and two sensitivity analyses were conducted.Results: No differences between the intervention and the control group were found in quality adjusted life years and total societal costs. The results indicate that the intervention is likely to be cost-effective, compared to attention only. The findings of the sensitivity analyses point in the same direction.Conclusion: More research with larger samples is necessary to confirm the findings. The outcomes of this study may inform policy makers to decide which interventions will be included in policies. The guided Internet intervention may improve psychological care for people living with HIV and depressive symptoms, against low costs. Show less

Show moreBackground: Depressive and anxiety disorders have been linked to a dysregulated hypothalamus-pituitary adrenal (HPA)-axis. Hair cortisol levels (HairF) reflect integrated long-term cortisol regulation and are therefore promising endocrine markers of chronic (psychological and physical) stress.Our aim was to assess hair cortisol levels in persons with a depressive and/or anxiety disorder and to compare their levels with that of persons in remission and healthy controls.Methods: Data from 1166 participants of the Netherlands Study of Depression and Anxiety (NESDA) were used, including 266 participants with a recent (1-month) diagnosis of a depressive and/or anxiety disorder, 655 participants with a diagnosis in remission, and 245 healthy controls. HairF was measured in the proximal three cm of scalp hair, using LC-MS/MS.Results: Compared to the healthy controls no differences on HairF or HairE levels were found for depressive and anxiety disorders alone. However the presence of a comorbid depressive and anxiety disorder was significantly associated with increased HairF levels (beta = 0.07; p = .031), as was the severity of depressive symptoms (beta = 0.06; p = .029), but no differences were found on HairE nor the HairF:HairE ratio.Conclusions: Persons with current diagnosis of comorbid depression and anxiety show moderately higher levels of cortisol than patients with only depression or anxiety, or patients in remission and healthy controls, which may be indicative of a chronic state of hyperactivation of the HPA axis.

Show moreBackground: : Psychiatric disorders are associated with overweight/obesity. Obsessive-compulsive disorder(OCD) may be an exception, as anecdotal evidence suggests lower BMI in OCD. Additionally, depression isassociated with elevated BMI, but effects of comorbid secondary depression are unknown. The aim of the presentstudy was to assess BMI and risk for overweight/obesity in OCD and to assess the effect of comorbid depressionon BMI.Methods: : BMI, demographics, and clinical status were assessed in large samples of individuals with OCD,anxiety disorders, depressive disorders, comorbid anxiety/depressive disorders, and non-clinical controls (NCC).Results: : Although no initial differences were found between the samples on BMI, the non-depressed OCDsubsample had significantly lower BMI and risk for overweight/obesity compared to all other clinical samples.NCC were nearly twice as likely to be overweight compared to non-depressed OCD.Limitations: : Eating disorders were excluded in the OCD sample, but BMI < 17 was used as an exclusion cri-terion in the clinical control groups in lieu of screening for Anorexia. Group differences on demographics werecontrolled for. Recruitment methodology differed between samples.Conclusions: : OCD is associated with significantly lower rates of obesity and overweight, but this relationshipwas not found when comorbid depression was present. This suggests that the purer the phenotype of OCD, themore substantial protective factor against overweight/obesity emerges compared to other clinical samples andNCC. An OCD-specific reward/anhedonia model, previously offered to elucidate lower smoking rates in OCD,may account for lower BMI in OCD. These results warrant careful clinical attention to the negative impact ofcomorbid depression on OCD that spans from increasing risk for obesity and cigarette smoking, to hinderingtreatment response.

Show moreBackground In older people, both apathy and depression (which frequently co-occurs with apathy) have been associated with poor physical functioning, a major health concern. We investigated the association between apathy and physical functioning in older people without dementia and whether this association is modified by depression.Methods We used the data from 380 older participants (with and without depression) taking part in the Netherlands Study of Depression in Older Persons, with baseline scores on the Apathy Scale and baseline and 2-year follow-up scores on at least one measure of physical functioning. These included the International Physical Activities Questionnaire (IPAQ, self-reported), WHO Disability Assessment Schedule (WHO-DASII mobility subset, self-reported), walking speed, or handgrip strength. Multivariable linear regression analyses were performed to examine the association between apathy at baseline and physical functioning at 2-year follow-up. We also investigated effect modification by sex, age, and depression.Results Cross-sectionally, participants with higher baseline Apathy Scale scores performed significantly worse on all measures of physical functioning. Longitudinally, higher baseline Apathy Scale scores were associated with higher delta scores on the IPAQ (B = -59.81) in the basic model, and higher delta scores on the WHO-DASII (B = .09) in all models. Apathy was not associated with higher delta scores for walking speed or handgrip strength. Furthermore, sex, age, and depression did not modify any association.Conclusion In a Dutch cohort of older people without dementia, apathy was associated with more decline in self-reported, but not in objective physical functioning. Sex, age, and depression did not modify these associations. In older people with apathy, subjective decline may precede decline in physical performance tests. Show less
