DeltaScan for the Assessment of Acute Encephalopathy and Delirium in ICU and non-ICU Patients, a Prospective Cross-Sectional Multicenter Validation Study.

OBJECTIVES: To measure the diagnostic accuracy of DeltaScan: a portable real-time brain state monitor for identifying delirium, a manifestation of acute encephalopathy (AE) detectable by polymorphic delta activity (PDA) in single-channel electroencephalograms (EEGs). DESIGN: Prospective cross-sectional study. SETTING: Six Intensive Care Units (ICU's) and 17 non-ICU departments, including a psychiatric department across 10 Dutch hospitals. PARTICIPANTS: 494 patients, median age 75 (IQR:64-87), 53% male, 46% in ICUs, 29% delirious. MEASUREMENTS: DeltaScan recorded 4-minute EEGs, using an algorithm to select the first 96 seconds of artifact-free data for PDA detection. This algorithm was trained and calibrated on two independent datasets. METHODS: Initial validation of the algorithm for AE involved comparing its output with an expert EEG panel's visual inspection. The primary objective was to assess DeltaScan's accuracy in identifying delirium against a delirium expert panel's consensus. RESULTS: DeltaScan had a 99% success rate, rejecting 6 of the 494 EEG's due to artifacts. Performance showed and an Area Under the Receiver Operating Characteristic Curve (AUC) of 0.86 (95% CI: 0.83-0.90) for AE (sensitivity: 0.75, 95%CI=0.68-0.81, specificity: 0.87 95%CI=0.83-0.91. The AUC was 0.71 for delirium (95%CI=0.66-0.75, sensitivity: 0.61 95%CI=0.52-0.69, specificity: 72, 95%CI=0.67-0.77). Our validation aim was an NPV for delirium above 0.80 which proved to be 0.82 (95%CI: 0.77-0.86). Among 84 non-delirious psychiatric patients, DeltaScan differentiated delirium from other disorders with a 94% (95%CI: 87-98%) specificity. CONCLUSIONS: DeltaScan can diagnose AE at bedside and shows a clear relationship with clinical delirium. Further research is required to explore its role in predicting delirium-related outcomes.

Trends in emotional functioning and psychosocial wellbeing in breast cancer survivors: a prospective cohort study using patient-reported outcome measures.

BACKGROUND: A breast cancer diagnosis can threaten every aspect of a woman's wellbeing, including her mental health. With the growing number of breast cancer survivors, studies addressing mental health in this population are of increasing importance now more than ever. Therefore, the current study investigated trends in emotional functioning and psychosocial wellbeing of breast cancer survivors, and the demographic and treatment characteristics that may influence these trends. METHODS: Prospectively collected data of women treated for breast cancer at the Erasmus MC were analyzed in this study using a cohort study design. Emotional functioning was measured using the EORTC-QLQ-C30, while psychosocial wellbeing was measured using the BREAST-Q. Type of surgery, age, family status and employment status of study participants were retrieved, and multilevel analyses were performed to identify trends in emotional functioning and psychosocial wellbeing and to determine the relationship between aforementioned characteristics and these outcomes. RESULTS: Three hundred thirty-four cancer survivors were analyzed. Psychosocial wellbeing declined, but emotional functioning showed a steady improvement over time. Women who underwent breast reconstruction showed a steeper increase in their emotional functioning, and women with no partner or children showed a marginal decline in psychosocial wellbeing between baseline and 12 months after surgery. CONCLUSIONS: These findings can be utilized by healthcare teams to identify breast cancer patients at risk for emotional problems and to provide adequate psychological support to those women who need help dealing with their emotions and self-concept in order to optimize clinical treatment.

[Organ donation after euthanasia in patients with a mental disorder: extra caution required]. / Orgaandonatie na euthanasie bij patiënten met een psychische stoornis.

A relative high number of cases of organ donation after euthanasia (ODE) is performed in patients with a mental disorder. We feel there are morally relevant differences between people who receive euthanasia on grounds of somatic illness and those who receive it on grounds of a mental disorder. More research is needed before it can be assumed that patients with a mental disorder who have their requests for euthanasia granted may also be eligible for ODE without further testing. Until then, as a matter of prudence, a request for ODE from a patient with a mental disorder should also be reviewed by a psychiatrist.

Symptom dimensions of depression and anxiety and the metabolic syndrome.

OBJECTIVE: To investigate the association between depression and anxiety symptoms and the metabolic syndrome (MetSyn), using a dimensional approach. The association between depression and anxiety, on the one hand, and the MetSyn as a cluster or its individual components, on the other hand, is equivocal. The categorical nature of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition might partly explain the inconsistent findings. METHODS: In 2,433 Netherlands Study of Depression and Anxiety participants (mean age, 42.3 years; 33.1% male), three symptoms dimensions-lack of positive affect (PA, depression specific); negative affect (NA, aspecific); and somatic arousal (SA, anxiety specific)-were assessed by a shortened adaptation of the Mood and Anxiety Symptom Questionnaire. The association between symptom dimensions and MetSyn components (waist circumference, triglycerides, high-density lipoprotein cholesterol, glucose, and mean blood pressure) was analyzed, using linear regression analysis. RESULTS: The occurrence rate of the MetSyn was 20.1% (n = 490). SA, but not PA and NA, was strongly associated with four out of five MetSyn components, especially waist circumference, triglycerides, and blood pressure (ß = 0.046, p = .01; ß = 0.077, p < .001; and ß = 0.069, p < .001, respectively), and with the total number of MetSyn components (ß = 0.098, p < .001). CONCLUSIONS: Our results demonstrate a strong association of most of the MetSyn components with the SA dimension, but not with the NA and PA scales.

The metabolic syndrome and related characteristics in major depression: inpatients and outpatients compared: metabolic differences across treatment settings.

OBJECTIVE: We aimed to systematically compare patients with major depressive disorder from three different treatment settings (a primary care outpatient, a secondary care outpatient and one inpatient sample), with regard to metabolic syndrome (MetSyn) prevalences, individual MetSyn components and related metabolic variables. METHOD: The outpatient samples were drawn from the ongoing Netherlands Study of Depression and Anxiety (302 primary care and 445 secondary care outpatients). The inpatient sample (n=80) was recruited from five Dutch mental health hospitals. The assessments of MetSyn and related variables [waist circumference (WC), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol, triglycerides, glucose, systolic and diastolic blood pressure (SBP, DBP), body mass index (BMI), waist-hip ratio (WHR), LDL and total cholesterol (TC)] were compared using analysis of (co)variance and regression analysis, whereas medication analyses examined the extent to which clinical differences (e.g., depression severity or medication use) mediated the observed metabolic differences across setting. RESULTS: MetSyn prevalences (26% primary, 24% secondary care and 28% inpatients) did not significantly differ (P=.71). WC, BMI, LDL cholesterol, glucose and DBP were not significantly different across settings. However, WHR, TC and triglyceride levels were higher in inpatients than in both outpatients groups, while HDL cholesterol levels and SBP were lower. There was some mediating role for tricyclic and non-selective serotonin-reuptake inhibitor antidepressant use, but overall, the mediating role of clinical differences was limited. CONCLUSIONS: Although overall MetSyn prevalences did not differ, patterns of individual MetSyn-related variables differed more markedly across depressed inpatients and outpatients. Inpatients showed more adverse WHR and serum lipid profiles, while SBP levels were lower.

Antidepressants and lethal violence in the Netherlands 1994-2008.

RATIONALE: There is an ongoing discussion on the relation between risk of violent behaviour and the use of antidepressants. The claim that the use of antidepressants can cause violent behaviour would gain credibility if a positive association between the two could be established. OBJECTIVE: The objective of this study is to evaluate the relationship between homicide, suicide and homicide-suicide rates and the rates of antidepressant use by gender and age group. METHOD: Nationwide data from the Netherlands on antidepressant prescriptions (ADs, SSRI and venlafaxine) and lethal violence were analysed over the 15-year period from 1994 to 2008. RESULTS: The findings indicated a significant negative association between lethal violence (homicide and suicide) and prescription of antidepressants in the Netherlands, indicating that in a period in which the exposure of the Dutch population to antidepressants increased, rates of lethal violence decreased. CONCLUSIONS: These data lend no support for an important role of antidepressant use in lethal violence.

Prevention of postpartum psychosis and mania in women at high risk.

OBJECTIVE: Women with a history of bipolar disorder or postpartum psychosis are at extremely high risk of relapse postpartum. Although lithium prophylaxis has demonstrated efficacy in reducing postpartum relapse, the timing of prophylaxis remains controversial given the balance of risks and benefits for the mother and fetus. The authors compared lithium use during pregnancy to its initiation postpartum in women at high risk for postpartum psychosis. METHOD: Between 2003 and 2010, 70 pregnant women at high risk for postpartum psychosis were referred to the authors' psychiatric outpatient clinic. Women who were initially medication free were advised to start lithium prophylaxis immediately postpartum. Women already taking maintenance lithium during pregnancy were advised to continue treatment. RESULTS: All women with a history of psychosis limited to the postpartum period (N=29) remained stable throughout pregnancy despite being medication free. Of the women with bipolar disorder (N=41), 24.4% relapsed during pregnancy, despite prophylaxis use by the majority throughout pregnancy. The postpartum relapse rate was highest in women with bipolar disorder who experienced mood episodes during pregnancy (60.0%). In contrast, none of the 20 women with a history of postpartum psychosis only who used postpartum prophylaxis relapsed, compared to 44.4% of patients with postpartum psychosis only who declined prophylaxis. CONCLUSIONS: The authors recommend initiating prophylactic treatment immediately postpartum in women with a history of psychosis limited to the postpartum period, to avoid in utero fetal exposure to medication. Patients with bipolar disorder require continuous prophylaxis throughout pregnancy and the postpartum period to reduce peripartum relapse risk.

Overweight, obesity, and depression: a systematic review and meta-analysis of longitudinal studies.

CONTEXT: Association between obesity and depression has repeatedly been established. For treatment and prevention purposes, it is important to acquire more insight into their longitudinal interaction. OBJECTIVE: To conduct a systematic review and meta-analysis on the longitudinal relationship between depression, overweight, and obesity and to identify possible influencing factors. DATA SOURCES: Studies were found using PubMed, PsycINFO, and EMBASE databases and selected on several criteria. STUDY SELECTION: Studies examining the longitudinal bidirectional relation between depression and overweight (body mass index 25-29.99) or obesity (body mass index > or =30) were selected. DATA EXTRACTION: Unadjusted and adjusted odds ratios (ORs) were extracted or provided by the authors. DATA SYNTHESIS: Overall, unadjusted ORs were calculated and subgroup analyses were performed for the 15 included studies (N = 58 745) to estimate the effect of possible moderators (sex, age, depression severity). Obesity at baseline increased the risk of onset of depression at follow-up (unadjusted OR, 1.55; 95% confidence interval [CI], 1.22-1.98; P < .001). This association was more pronounced among Americans than among Europeans (P = .05) and for depressive disorder than for depressive symptoms (P = .05). Overweight increased the risk of onset of depression at follow-up (unadjusted OR, 1.27; 95% CI, 1.07-1.51; P < .01). This association was statistically significant among adults (aged 20-59 years and > or =60 years) but not among younger persons (aged <20 years). Baseline depression (symptoms and disorder) was not predictive of overweight over time. However, depression increased the odds for developing obesity (OR, 1.58; 95% CI, 1.33-1.87; P < .001). Subgroup analyses did not reveal specific moderators of the association. CONCLUSIONS: This meta-analysis confirms a reciprocal link between depression and obesity. Obesity was found to increase the risk of depression, most pronounced among Americans and for clinically diagnosed depression. In addition, depression was found to be predictive of developing obesity.
