Background: Despite the frequent co-occurrence of posttraumatic stress disorder and substance use disorder, screening for trauma exposure and posttraumatic stress disorder symptoms is not a routine practice in substance use disorder clinics. The aims of this study were to examine the prevalence of exposure to traumatic events, posttraumatic stress disorder symptoms, and subjective sleep quality in substance use disorder inpatients after detoxification. In addition, we analyzed associations of sociodemographics, direct and indirect exposure to traumatic events, and sleep quality with posttraumatic stress disorder symptom severity., Methods: Adults diagnosed with substance use disorder (n = 188; 25% women, mean age 46.6 ± 12.3 years) from 2 inpatient addiction clinics were assessed at approximately 4 days post-admission for age, gender, educational level, self-reported substance use, trauma exposure, general and posttraumatic stress disorder-specific subjective sleep quality, and posttraumatic stress disorder symptom severity. Correlates of posttraumatic stress disorder symptom severity were identified with linear regression analyses., Results: The prevalence of direct trauma exposure was high (89%), 51% of participants screened positive for posttraumatic stress disorder and 87% reported clinically significant poor sleep quality. Younger age, female gender, direct and indirect exposure to more traumatic events, and poor subjective sleep quality were associated with more severe posttraumatic stress disorder symptoms., Conclusion: Nearly all substance use disorder patients admitted for detoxification in our study had been directly or indirectly exposed to 1 or more traumatic events, and many reported posttraumatic stress disorder symptoms and poor sleep quality. Younger and female substance use disorder patients were at higher risk of posttraumatic stress disorder symptoms. Our results emphasize the need for systematic screening for direct and indirect trauma exposure, posttraumatic stress disorder symptoms, and poor sleep quality in patients admitted for clinical substance use disorder treatment., (2022 authors.)

Objective: The objective of this study was to predict rehospitalisation in a psychiatric clinic in older inpatients with a psychotic disorder., Methods/design: In this prospective, observational study, all eligible inpatients aged 55 years and over with a primary psychotic disorder, admitted to a specialised ward for older psychotic patients in a large psychiatric inpatient clinic in the Netherlands, were asked to participate. Whether or not patients were rehospitalised and time to rehospitalisation were assessed 1 year after discharge from the ward. We recorded age, gender, living arrangement, psychiatric diagnosis, severity of psychotic symptoms, duration of index episode, age of onset of psychotic disorder, number of previous admissions, involuntary admission and use of depot medication at discharge. All patients underwent a neuropsychological assessment., Results: Of the 90 patients that were included, 32 (35.6%) had been readmitted within 1 year after discharge. None of the demographic or clinical variables predicted rehospitalisation or the time to rehospitalisation., Conclusion: Factors that predict rehospitalisationin younger adult patients with schizophrenia may not predict rehospitalisationin older patients with a psychotic disorder, of which the majority suffered from schizophrenia. We expect that other factors than those investigated may be of greater importance to predict rehospitalisation, as for example social support and coping mechanisms., (© 2020 John Wiley & Sons Ltd.)

Caffeine is often used to reduce sleepiness; however, research suggests that it can also cause poor sleep quality. The timing of caffeine use, amongst other factors, is likely to be important for the effects it has on sleep quality. In addition, individual differences exist in the effect of caffeine on sleep quality. This cross-sectional study investigated the influence of the timing of caffeine consumption on and a possible moderating role of chronotype in the relationship between caffeine consumption and sleep quality in 880 students (74.9% female, mean age 21.3 years, SD = 3.1). Respondents filled in online questionnaires about chronotype (the Morningness-Eveningness Questionnaire), sleep quality (the Pittsburgh Sleep Quality Index) and caffeine consumption. Mean caffeine consumption was 624 mg per week, and 80.2% of the sample drank caffeine after 18:00 hours. Regression analyses demonstrated that higher total caffeine consumption was only related to poorer sleep quality for people who did not drink caffeine in the evening (β = 0.209, p = .006). We did not find a relationship between caffeine and sleep quality in people who drank caffeine in the evening (β = -0.053, p = .160). Furthermore, we found no evidence for a moderating role of chronotype in the relationship between caffeine consumption and sleep quality. We concluded that a self-regulating mechanism is likely to play a role, suggesting that students who know that caffeine negatively affects their sleep quality do not drink it in the evening. Caffeine sensitivity and the speed of caffeine metabolism may be confounding variables in our study., (© 2018 The Authors.

Individuals with an evening chronotype are at increased risk of experiencing emotional problems, including depressive symptoms. However, the mechanisms underlying these associations remain unclear. The present study aimed to determine whether poor sleep quality, substance use and cognitive emotion regulation difficulties - which have been implicated in the etiology of depression - mediate the relationship between chronotype and depressive symptoms in a student sample, which was assessed cross-sectionally and after 1 year. A total of 742 Dutch students (75% women, mean age 21.4 ± 2.9 years) completed the Quick Inventory of Depressive Symptomatology, the Morningness-Eveningness Questionnaire, the Pittsburgh Sleep Quality Index, a questionnaire assessing alcohol, caffeine, tobacco and cannabis use, the Cognitive Emotion Regulation Questionnaire and the Behavioral Inhibition/Activation Scale. A subsample (n = 115) was assessed 1 year later with the same questionnaires. Cross-sectional analyses showed that evening chronotype was associated with more depressive symptoms, adjusted for age and gender (β = -0.082, p = 0.028). The relationship between eveningness and depressive symptoms was mediated by sleep quality, alcohol consumption and the cognitive emotion regulation strategies of self-blame and positive reappraisal. In longitudinal analyses, eveningness at baseline predicted more depressive symptoms at follow-up, adjusted for age and gender (β = -0.29, p = 0.002); after additional adjustment for baseline depressive symptoms, chronotype remained a significant predictor of depressive symptoms at T2 (β = -0.16, t = -2.01, p = 0.047). Only poor sleep quality at follow-up was a significant mediator of this relationship. Even though the effect is small in terms of explained variance, eveningness is related to depressive symptoms and this relationship is mediated by poor sleep quality, also in a prospective design. Self-blame and reduced positive reappraisal are correlated with eveningness. Further research is needed to assess the efficacy of chronotherapeutic interventions for the prevention of depression, in addition to sleep education and cognitive approaches.

Objectives: To investigate whether lifestyle indicators including physical exercise, sleep duration, alcohol use, body mass index, smoking status, and a composite lifestyle index are associated with the depression course in older adults., Methods: Data of 283 older adults were used from the Netherlands Study of Depression in Older Persons. Depressive disorders at baseline were assessed with the Composite International Diagnostic Interview. The depression course at 2-year follow-up was assessed with the Inventory of Depressive Symptoms (IDS, score 0-84) every 6 months; physical exercise with the International Physical Activity Questionnaire; alcohol use with the Alcohol Use Disorders Identification Test; body mass index by anthropometry; and sleep duration and smoking status by interview questions. A composite lifestyle index was calculated by summing scores assigned to each lifestyle factor, with a higher score indicating healthier behavior., Results: Of all participants, 61.1% had chronic depression (all IDS scores 14-84), 20.1% had intermittent depression (1 IDS score ≤ 14), and 18.7% remitted depression (last 2 IDS scores ≤14). None of the investigated lifestyle indicators, nor the composite lifestyle index was associated with depression course, after adjustment for covariates., Conclusions: Lifestyle factors do not predict the course of depression at 2-year follow-up in older adults., (© 2018 The Authors.

Objectives: Many patients with dementia develop agitation or aggression in the course of their disease. In some severe cases, behavioral, environmental, and pharmacological interventions are not sufficient to alleviate these potentially life-threatening symptoms. It has been suggested that in those cases, electroconvulsive therapy (ECT) could be an option. This review summarizes the scientific literature on ECT for agitation and aggression in dementia., Methods: We performed a systematic review in accordance with PRISMA guidelines. A search was conducted in Ovid MEDLINE, EMBASE, and PsycINFO. Two reviewers extracted the following data from the retrieved articles: number of patients and their age, gender, diagnoses, types of problem behavior, treatments tried before ECT, specifications of the ECT treatment, use of rating scales, treatment results, follow-up data, and adverse effects., Results: The initial search yielded 264 articles, 17 of which fulfilled the inclusion criteria. Of these studies, one was a prospective cohort study, one was a case-control study, and the others were retrospective chart reviews, case series, or case reports. Clinically significant improvement was observed in the majority (88%) of the 122 patients described, often early in the treatment course. Adverse effects were most commonly mild, transient, or not reported., Conclusions: The reviewed articles suggest that ECT could be an effective treatment for severe and treatment-refractory agitation and aggression in dementia, with few adverse consequences. Nevertheless, because of the substantial risk of selection bias, the designs of the studies reviewed, and their small number, further prospective studies are needed to substantiate these preliminary positive results., (Copyright © 2017 American Association for Geriatric Psychiatry.

Objectives: Sleep disturbances are common among depressed older persons. To gain insight into sleep disturbances in late-life depression, their occurrence and correlates were assessed., Methods: Baseline data of 294 depressed older persons of the Netherlands Study of Depression in Older persons study were used. A diagnosis of current depression according to the diagnostic and statistical manual of mental disorders-IV (DSM-IV) was assessed with the Composite International Diagnostic Interview. Sleep disturbances were measured with the five-item Women's Health Initiative Insomnia Rating Scale, and considered present with a score of ≥10 points., Results: Sleep disturbances were present in 59.9% of the depressed older persons. Bivariate linear regression analyses showed that presence of sleep disturbances was associated with fewer years of education, use of alcohol, the number of chronic diseases, higher pain intensity scores, use of more benzodiazepines, more anxiety and severity of depressive symptoms. In multivariate analyses, severity of depression appeared to be the only independent correlate., Conclusions: Sleep disturbances are highly prevalent in patients with late-life depression and independently correlated with the severity of depression. Treatment of depression may result in improvement of sleep disturbances, although cognitive behavioral interventions that focus on both depression and sleep disturbances may also be effective.

Objective: Research suggests that in depression, vascular burden predicts a lower efficacy for medication (MED) and a more favourable outcome for electroconvulsive therapy (ECT). Therefore, we investigated the influence of the following vascular risk factors (VRF): hypercholesterolemia, hypertension, smoking, diabetes mellitus, cardiovascular disease, and cerebral vascular accident/transient ischemic attack, on remission from major depression after ECT versus MED., Methods: The study sample consisted of 81 inpatients with a DSM-IV unipolar major depression diagnosis (mean age 72.2 years, SD = 7.6, mean Montgomery-Åsberg Depression Rating Scale score 32.9, SD = 6.2) participating in a randomized controlled trial comparing nortriptyline versus venlafaxine and 43 inpatients (mean age 73.7 years, SD = 7.5, mean Montgomery-Åsberg Depression Rating Scale score 30.6, SD = 7.1) from an randomized controlled trial comparing brief pulse versus ultrabrief pulse ECT. The presence of VRF was established from the medical records. The remission rate of patients with VRF was compared with those of patients without VRF., Results: The remission rate was 58% (19/33) in the ECT group with ≥1 VRF and 32% (23/73) in the MED group with ≥1 VRF (χ 2  = 6.456, p = 0.011). Comparing patients with no VRF versus ≥1 VRF, the remission rate decreased from 80 to 58% (χ 2  = 1.652, p = 0.276) in ECT patients and from 38 to 32% (χ 2  = 0.119, p = 0.707) in MED patients. Applying different cut-offs for the number of VRFs yielded the same trends. Logistic regression revealed no interaction between VRF and treatment condition., Conclusion: The superior efficacy of ECT over pharmacotherapy in major depression in older age was independent of the presence of VRF.

Insomnia symptoms are highly prevalent in depressed older adults. This study investigates the association between hypothalamic-pituitary-adrenal (HPA) axis activity and symptoms of insomnia, respectively, sleep duration among 294 depressed and 123 non-depressed older adults of the Netherlands Study of Depression in Older people (NESDO) study. Insomnia symptoms were defined as clinically relevant when having a score ≥ 10 points on the Women's Health Initiative Insomnia Rating Scale (WHIIRS). Sleep duration was categorized in short (≤ 6 h per night), normal (7-8 h per night) and long (≥ 9 h per night) duration. Salivary cortisol levels were used to assess the following cortisol parameters for HPA axis activity: area under the curve with respect to the increase (AUCi) and to the ground (AUCg), diurnal slope, evening cortisol level and dexamethasone suppression ratio. Clinically relevant insomnia symptoms were present in 46% of the participants. Thirty-two per cent of the participants were short sleepers, whereas 16% were long sleepers. However, univariate analyses showed no differences in any of the HPA axis parameters between people with and without insomnia symptoms or between the three groups with different sleep duration. In addition, no significant interaction was found between a diagnosis of depression or the severity of depressive symptoms and any of the cortisol parameters in relation to insomnia symptoms or sleep duration., (© 2017 European Sleep Research Society.)

Background: Alcohol dependence is associated with impairments in cognition, especially in later life. Previous studies suggest that excessive drinking has more negative impact on cognition in women than in men., Objectives: In this study, differences in cognition between male and female older, alcohol-dependent patients were examined., Method: Older alcohol-dependent inpatients (N = 164, 62.2% men, mean age 62.6 ± 6.4) underwent neuropsychological tests of sensitivity to interference, mental flexibility, and visual processing., Results: No gender differences were found in age, educational level, estimated premorbid verbal intelligence, and sensitivity to interference. Duration of alcohol dependence was longer for men than for women. Men performed better than women on visual processing, and women better than men on mental flexibility. The superior mental flexibility of women remained significant after adjustment for duration of alcohol dependence. Conclusions/Importance: Older alcohol-dependent inpatients performed below average on cognitive tasks, which suggests that long-term excessive alcohol use negatively affects cognition. Our study does not demonstrate more severe cognitive impairment in women than in men.

Background: As a result of effective combination antiretroviral therapy (cART) and advanced supportive healthcare, a growing number of human immunodeficiency virus (HIV)-infected children survive into adulthood. The period of transition to adult care is often associated with impaired adherence to treatment and discontinuity of care. We aimed to evaluate virological and social outcomes of HIV-infected adolescents and young adults (AYAs) before and after transition, and explore which factors are associated with virological failure., Methods: We included 59 HIV-infected AYAs from the Netherlands who had entered into pediatric care and transitioned from pediatric to adult healthcare. We used HIV RNA load and cART data from the Dutch Stichting HIV Monitoring database (1996-2014), and collected social and treatment data from patients' medical records from all Dutch pediatric HIV treatment centers and 14 Dutch adult treatment centers involved. We evaluated risk factors for virological failure (VF) in a logistic regression model adjusted for repeated measurements., Results: HIV VF occurred frequently during the study period (14%-36%). During the transition period (from 18 to 19 years of age) there was a significant increase in VF compared with the reference group of children aged 12-13 years (odds ratio, 4.26 [95% confidence interval, 1.12-16.28]; P = .03). Characteristics significantly associated with VF were low educational attainment and lack of autonomy regarding medication adherence at transition., Conclusions: HIV-infected AYAs are vulnerable to VF, especially during the transition period. Identification of HIV-infected adolescents at high risk for VF might help to improve treatment success in this group., (© The Author 2016.

There has been an increasing interest in the identification of genetic variants causing individual differences in human behavior. Psychiatrists have contributed to the genetics field by defining the most important behavioral characteristics and by studying the association between genetic variants and behavioral differences within phenotypically well-characterized samples in which detailed assessments have been collected (e.g. neuroimaging). These samples are typically limited in size and are therefore not suitable for a genome-wide association analysis. Instead, gene association studies conducted in such samples typically focus on a few genes of interest, allowing smaller sample sizes. However, the selection of high-priority genes is not always straightforward and psychiatrists will usually have a limited background in genetics. We aim to fill this gap by (i) providing a basic introduction to genetics; (ii) showing how the selection of genes of interest can be optimized by the use of two web tools: Polysearch and Gene Prospector; (iii) illustrating how statistical power analyses can be performed and discussing the importance of sufficiently powered studies. This guide can help psychiatrists with limited experience in genetics in designing genetic studies that allow identification of specific behavioral, cognitive, or neural correlates of genetic risk variants, while avoiding common pitfalls.

Background and Objectives: Alcohol dependence is often a chronic relapsing disorder with frequent admissions to inpatient facilities. This study in older alcohol-dependent inpatients investigates the role of social factors in readmissions after inpatient detoxification., Methods: In a prospective study, 132 older alcohol-dependent patients admitted to inpatient detoxification (mean age 63.4, SD = 6.6, 39.4% women) were interviewed with the European version of the Addiction Severity Index (Europ-ASI). Readmission to inpatient treatment was monitored up to 1 year after discharge. The effect of social factors on readmission, the number of readmissions and the time to first readmission was established using group comparisons, Poisson regression analysis, and Cox' proportional hazards regression analysis, respectively., Results: Sixty-seven (50.8%) of the 132 patients were readmitted within 1 year. In this group, the median number of readmissions was 2 (IQR = 2, range 1-6) and the median time to first readmission was 88 days (IQR = 116, range 3-356). In a multivariate analysis, spending most leisure time alone predicted fewer readmissions. None of the other social factors predicted readmission, number of readmissions or time to first readmission., Discussion and Conclusions: Rehospitalization of older alcohol-dependent patients after detoxification is very common, and generally not predicted by social factors. Only spending most leisure time alone may play a role., Scientific Significance: This study shows that most social factors are-unexpectedly-not associated with rehospitalization of older alcohol-dependent patients after detoxification. "Spending leisure time alone" warrants further study as a potentially modifiable predictor., (© American Academy of Addiction Psychiatry.)

Background: Severe depression can be a life-threatening disorder, especially in elderly patients. A fast-acting treatment is crucial for this group. Electroconvulsive therapy (ECT) may work faster than medication., Aims: To compare the speed of remission using ECT v. medication in elderly in-patients., Method: The speed of remission in in-patients with a DSM-IV diagnosis of major depression (baseline MADRS score ≥20) was compared between 47 participants (mean age 74.0 years, s.d. = 7.4) from an ECT randomised controlled trial (RCT) and 81 participants (mean age 72.2 years, s.d. = 7.6) from a medication RCT (nortriptyline v. venlafaxine)., Results: Mean time to remission was 3.1 weeks (s.d. = 1.1) for the ECT group and 4.0 weeks (s.d. = 1.0) for the medication group; the adjusted hazard ratio for remission within 5 weeks (ECT v. medication) was 3.4 (95% CI 1.9-6.2)., Conclusions: Considering the substantially higher speed of remission, ECT deserves a more prominent position in the treatment of elderly patients with severe depression., (Royal College of Psychiatrists.)

Background: Alcohol dependence in older adults is associated with cognitive impairment. Age of onset of alcohol dependence is an important criterion to distinguish subgroups of alcohol-dependent people. Little is known about the influence of the age of onset of alcohol dependence on cognitive functioning. The primary aim of this study was to examine if older alcohol-dependent people with early, late or very late onset of alcohol dependence differ in terms of cognitive dysfunction., Methods: A total of eighty-five older alcohol-dependent people who were admitted to an inpatient detoxification program, were categorized into three age of onset groups: early onset (< 25 years: N = 27, mean age 57.7 ± 7.4), late onset (25-44 years: N = 28, mean age 61.1 ± 6.7) and very late onset (≥ 45 years: N = 30, mean age 65.6 ± 6.5). A neuropsychological test battery (Kaufman-Short Neuropsychological Assessment Procedure (K-SNAP), Trail Making Test (TMT) and Stroop Color Word Test) was administered to assess cognitive functioning. Differences between groups were examined with analyses of variance (ANOVAs)., Results: There were no significant differences in performance on any of the neuropsychological measures between the three age of onset groups. However, compared to a non-alcohol-dependent norm group, all three age of onset groups performed below average., Conclusions: The results suggest that older adults who start drinking heavily (very) late in life have similar cognitive impairments compared to their peers who have been drinking for decades. This emphasizes the vulnerability of the aging brain to the toxic effects of alcohol.

Objectives: To compare alcohol use between depressed and nondepressed older adults, and to investigate correlates of alcohol abstinence and at-risk alcohol consumption in depressed older adults., Design: Cross-sectional study., Setting: Netherlands Study of Depression in Older Persons (NESDO)., Participants: A total of 373 participants (mean [standard deviation] age: 70.6 [7.3] years; 66% women) diagnosed with a depressive disorder, and 128 nondepressed participants., Measurements: Alcohol use was assessed with the Alcohol Use Disorders Identification Test (AUDIT). Participants were categorized into abstainers (AUDIT score: 0), moderate drinkers (AUDIT score: 1-4), and at-risk drinkers (AUDIT score: ≥5). Multinomial logistic regression analysis was performed with AUDIT categories as outcome, and demographic, social, somatic, and psychological variables as determinants., Results: The depressed group consisted of 40.2% abstainers, 40.8% moderate drinkers, and 19.0% at-risk drinkers. The depressed participants were more often abstinent and less often moderate drinkers than the nondepressed participants; they did not differ in at-risk drinking. Depressed abstainers more often used benzodiazepines but less often used antidepressants, and they had a poorer cognitive function than depressed moderate drinkers. Depressed at-risk drinkers were more often smokers and had fewer functional limitations but more severe depressive symptoms than depressed moderate drinkers., Conclusions: Although alcohol abstinence was more common in depressed than in nondepressed older adults, 19% of depressed persons were at-risk drinkers. Because at-risk drinking is associated with more severe depression and may have a negative impact on health and treatment outcome, it is important that physicians consider alcohol use in depressed older adults., (Copyright © 2014 American Association for Geriatric Psychiatry.

Aims: Age of onset is an important criterion to distinguish subgroups of alcohol-dependent patients. This study investigated physical and mental health and social functioning of older inpatients with early (age <25), late (25-44), and very late (≥45) onset of alcohol dependence., Methods: In a specialized detoxification ward for older patients in The Hague, the Netherlands, 157 older alcohol-dependent inpatients (38% women, mean age 62.7 ± 6.5) were interviewed with the European version of the Addiction Severity Index., Results: As a group, older alcohol-dependent patients had substantial physical, mental and social problems, which were largely independent of the age of onset of alcohol dependence. Patients with early-onset alcohol dependence had more chronic medical problems and more suicidal thoughts than patients with late-onset alcohol dependence. The very-late-onset group did not significantly differ from the other two groups in any of the variables under study., Conclusions: Despite previous studies showing more favourable outcomes for the (very) late-onset compared to the early-onset alcohol-dependent group, their comorbid (mental) health and social problems are in many respects similar, and require careful assessment and treatment. This may be crucial for successful treatment and improving quality of life in these patients., (© 2014 S. Karger AG, Basel.)

In clinical practice, the combination of brief, cost effective, valid and reliable assessment of personality disorders (PDs) is highly important. Substantial budget cuts require optimal use of the clinician's time. PDs are related with high axis I comorbidity, poorer therapy outcome and increased health service costs. In an effort to find a screening questionnaire that meets both the demands of cost-effectiveness and methodological soundness, we investigated the use of the Personality Diagnostic Questionnaire 4+ (PDQ-4+) as a first step in a two-step diagnostic procedure. As the second step, we used the Structured Clinical Interview of DSM-IV Axis II Personality Disorders (SCID-II) as criterion measure. Our results show that the positive predictive power of the PDQ-4+ is rather low, resulting in a large number of false positives. Therefore, its added value is poor in comparison with administering the SCID-II in the first place. Also, the value of the two validity scales of the PDQ-4+ is highly questionable. We therefore conclude that the PDQ-4+ should not be used in clinical practice as a screening instrument for PD assessment., (Copyright © 2011 John Wiley & Sons, Ltd.)

Study Objectives: We studied sleep duration and sleep quality in relation to cardiovascular disease (CVD) incidence., Design/setting: Dutch population-based cohort study., Participants: 20,432 men and women aged 20-65 and with no history of CVD., Interventions: N/A., Measurements: Sleep duration and sleep quality were assessed by a self-administered questionnaire. Morbidity data, vital status, and causes of death were obtained through linkage with several national registries. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were calculated using Cox proportional hazards models., Results: During 10-15 years of follow-up, 1,486 CVD and 1,148 coronary heart disease (CHD) events occurred. Short sleepers (≤ 6 h) had a 15% higher risk of total CVD (HR: 1.15; 95%CI: 1.00-1.32) and a 23% higher risk of CHD (HR: 1.23 [1.04-1.45]) compared to normal sleepers (7 h) after adjustment for all confounders. Additional adjustment for intermediate biological risk factors attenuated these relative risks to 1.11 (0.97-1.27) for total CVD and to 1.19 (1.00-1.40) for CHD. Short sleepers with poor sleep quality had a 63% higher risk of CVD (HR: 1.63 [1.21-2.19]) and a 79% higher risk of CHD incidence (HR: 1.79 [1.24-2.58]) compared to normal sleepers with good sleep quality, after adjustments for all confounders. We observed no associations between long sleep duration (≥ 9 h) and CVD or CHD incidence., Conclusions: Short sleepers, especially those with poor sleep quality, have an increased risk of total CVD and CHD incidence. Future investigations should not only focus on sleep duration, but should also take sleep quality into account.

The hypothesis that β-blockers cause depression has been both confirmed and refuted in previous studies. However, in hardly any of these studies, depression was systematically and adequately assessed. The aim of this cohort study was to examine whether β-blockers, in general, highly lipid-soluble, nonselective, or serotonergic receptor-binding β-blockers, are associated with incident depression. Between 1993 and 2005, 5104 elderly persons were followed for incident depressions. Depressions were identified by regular interview and continuous monitoring of medical records. Cases were categorized as clinically relevant depressive symptoms or as depressive syndromes, the latter including Diagnostic and Statistical Manual of Mental Disorders-IV-defined depressive disorders. Pharmacies provided information on filled β-blockers. We used Cox regression with drug use as a time-dependent variable to analyze the data, adjusted for potential demographic covariates, activity of daily living, and (contra)indications for β-blockers. We found that use of β-blockers in general did not convey an increased risk of depressive symptoms (hazard ratio [HR], 0.76; 95% confidence interval [CI], 0.37-1.59) or depressive syndromes (HR, 0.99; 95% CI, 0.53-1.84). Highly lipid-soluble β-blockers, mostly propranolol in our study, were associated with depressive symptoms during the first 3 months of use (HR, 3.31; 95% CI, 1.03-10.6), but not with depressive syndromes. Nonselective or serotonergic receptor affinity was not associated with an increased risk of depressive symptoms or syndromes independent of high lipid solubility. We conclude that β-blockers in general do not convey an increased risk of depression. Lipophilic β-blockers are associated with an increased risk of depressive symptoms.

Objectives: To assess whether heart failure (HF) increases the risk of developing depression and whether the use of loop diuretics in persons with HF alters this risk., Design: Population-based cohort study between 1993 and 2005., Setting: Ommoord, a district of Rotterdam, the Netherlands., Participants: Five thousand ninety-five older adults free of depression at baseline., Measurements: Detailed information on HF and depression was collected during examination rounds and through continuous monitoring of medical and pharmaceutical records. HF was defined according to the criteria of the European Society of Cardiology. Depressive episodes were categorized as clinically relevant depressive symptoms and depressive syndromes, including major depressive disorders defined according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria. Hazard ratios (HRs) were calculated using multivariate Cox proportional hazard regression., Results: HF was associated with greater risk of depressive symptoms and syndromes (HR=1.41, 95% CI=1.03-1.94) and depressive syndromes only (HR=1.66, 95% CI=1.09-2.52). In participants with HF, the use of loop diuretics was associated with a lower risk of depressive symptoms and syndromes (HR=0.46, 95% CI=0.22-0.96) and depressive syndromes only (HR=0.41, 95% CI=0.16-1.00)., Conclusion: HF is an independent risk factor for incident depression in elderly persons. Patient with HF require careful follow-up to monitor and prevent the onset of depression. Effective treatment of the debilitating symptoms of HF may prevent depression., (© 2010, Copyright the Authors. Journal compilation © 2010, The American Geriatrics Society.)

Objective: Sleep disturbance is common in psychiatric disorders. However, the relationships of core parameters in sleep research, such as total sleep time (TST), with depression and anxiety disorders are unclear and have rarely been investigated in large population-based studies., Method: This study was embedded in the Rotterdam Study, a community-based cohort study of elderly persons living in a district of Rotterdam, The Netherlands. Between January 2002 and December 2005, sleep parameters were assessed with the Pittsburgh Sleep Quality Index in 5,019 persons aged 58 to 100 years. DSM-IV-TR diagnoses of depressive and anxiety disorders were ascertained by psychiatric interview (the Schedules for Clinical Assessment in Neuropsychiatry for depressive disorders and a slightly adapted Munich version of the Composite International Diagnostic Interview for anxiety disorders). Associations between sleep parameters and psychiatric disorders were investigated with analyses of covariance and logistic regression models., Results: Both short-duration (< 6 hours per night) and long-duration (> or = 9 hours per night) sleepers were more likely to have a depressive disorder (P < .001) than were those sleeping 7 to < 8 hours per night; the association between TST and anxiety disorders was also U-shaped. These associations were stronger in people who did not use psychoactive medication but did not substantially change after exclusion of persons with probable sleep apnea or excessive alcohol use. Participants with a depressive disorder and a comorbid anxiety disorder reported a 1-hour shorter TST than persons with 1 disorder or no disorders (P < .001). On average, however, depressed persons spent more time in bed than did the nondepressed group., Conclusion: In a community-dwelling older population, not only insomnia or short sleep but also long sleep can be symptomatic of psychiatric disorders such as depression and anxiety disorders., (© Copyright 2009 Physicians Postgraduate Press, Inc.)

Introduction: 5-methoxytryptamine (5-MT), a precursor of serotonin, is considered to be an endogenous substrate of cytochrome P450 2D6 (CYP2D6). Homozygous carriers of the variant allele CYP2D6*4 lack CYP2D6 enzyme activity. Relative to extensive metabolizers, these poor metabolizers may have lower baseline serotonin concentrations in various brain regions, and may be more prone to depression or anxiety., Aim: To test whether the CYP2D6*4/*4 genotype is associated with a predisposition to depression or anxiety disorders in the elderly., Materials & Methods: We conducted a cross-sectional study within the Rotterdam Study, a population-based cohort study, among persons aged 55 years or older, who were screened for depression and anxiety disorders at two consecutive examination rounds. Logistic regression was used to analyze the association between the CYP2D6*4 polymorphism and the risk of depression or anxiety disorders., Results: The risk of major depression in CYP2D6*4/*4 was not significantly different from extensive metabolizers (OR = 0.85; 95% CI: 0.36-2.00; p = 0.72). Neither did we find an association between CYP2D6 genotype and minor depression (OR = 1.56; 95% CI: 0.69-3.52; p = 0.28). No increased risk of anxiety disorders was found (OR = 1.19; 95% CI: 0.68-2.09; p = 0.55)., Conclusion: Variation in the CYP2D6 gene is not related to a predisposition to depression or anxiety disorders in the elderly.

Context: Depression is common in old age. Nevertheless, few incidence studies have established how often depression occurs in elderly persons with and without a history of depression., Objectives: To determine the incidence and recurrence rates of depression in an elderly population., Design, Setting, and Participants: A cohort study of community-dwelling elderly persons aged 56 years or older residing in Rotterdam, the Netherlands, performed between September 1993 and October 2005 and encompassing baseline and 2 follow-up examinations as well as continuous procedures. The study population consisted of 5653 participants free of dementia. Depression was identified through standardized psychiatric examinations, monitoring of medical records, registration of antidepressant use, and self-reported histories of depression. We categorized the depression as depressive syndromes, including DSM-IV-defined major depression, or clinically relevant depressive symptoms., Main Outcome Measures: Incidence and recurrence rates for depressive syndromes as well as for depressive syndromes and symptoms combined. In addition to overall rates, sex- and age-specific rates were calculated., Results: During the follow-up period of 8 years on average, 566 depressive syndromes and 1073 episodes of clinically relevant depressive symptoms occurred. For depressive syndromes, the incidence rate was 7.0 (95% confidence interval, 6.0-8.3) per 1000 person-years and the recurrence rate was 27.5 (95% confidence interval, 23.7-32.1) per 1000 person-years. The incidence and recurrence rates more than doubled when episodes of depressive symptoms were included. The recurrence rate of depressive syndromes was equal for women and men, but all other rates were almost twice as high for women compared with men. No rates seemed to change with age., Conclusions: The incidence rate of depression in the elderly population is low except when episodes of clinically relevant depressive symptoms are accounted for. Most late-life depression occurs in persons with a history of depression. Moreover, the recurrence rate of depressive syndromes does not differ between men and women.

Sleep duration is an important concept in epidemiological studies. It characterizes a night's sleep or a person's sleep pattern, and is associated with numerous health outcomes. In most large studies, sleep duration is assessed with questionnaires or sleep diaries. As an alternative, actigraphy may be used, as it objectively measures sleep parameters and is feasible in large studies. However, actigraphy and sleep diaries may not measure exactly the same phenomenon. Our study aims to determine disagreement between actigraphic and diary estimates of sleep duration, and to investigate possible determinants of this disagreement. This investigation was embedded in the population-based Rotterdam Study. The study population consisted of 969 community-dwelling participants aged 57-97 years. Participants wore an actigraph and kept a sleep diary for, on average, six consecutive nights. Both measures were used to determine total sleep time (TST). In 34% of the participants, the estimated TST in the sleep diaries deviated more than 1 h from actigraphically measured TST. The level of disagreement between diary and actigraphic measures decreased with subjective and actigraphic measures of sleep quality, and increased with male gender, poor cognitive function and functional disability. Actigraphically measured poor sleep was often accompanied by longer subjective estimates of TST, whereas subjectively poor sleepers tended to report shorter TST in their diaries than was measured with actigraphy. We recommend, whenever possible, to use multiple measures of sleep duration, to perform analyses with both, and to examine the consistency of the results over assessment methods.

Objective: The epidemiological evidence for the association between sleep duration and obesity in the elderly is inconsistent and has not been investigated with objective measures. Furthermore, the role of sleep fragmentation in this relationship is unknown. Our aim was to investigate the association of sleep measures with body mass index (BMI) and obesity in a normal elderly population., Design: Cross-sectional study., Subjects: A total of 983 community-dwelling elderly (mean age 68.4+/-6.9 years, range, 57-97)., Measurements: Weight and height were measured, and sleep duration and fragmentation were assessed with on average six nights of actigraphy., Results: A quadratic model adequately described the association between continuous measures of sleep duration and BMI. Actigraphic sleep duration had a significant U-shaped relationship with BMI (beta of quadratic term=0.30, 95% confidence interval (CI): 0.08, 0.52). Both short sleepers (<5 h: OR, 2.76 (95% CI: 1.38, 5.49), 5 to <6 h: OR, 1.97 (95% CI: 1.26, 3.08)) and long sleepers (>or=8 h: OR, 2.93 (95% CI: 1.39, 6.16)) were more likely to be obese, compared to participants who slept 7 to <8 h. BMI increased with 0.59 kg m(-2) per standard deviation of sleep fragmentation (95% CI: 0.34, 0.84). After adjustment for sleep fragmentation, the association between short sleep and obesity was no longer significant. Exclusion of participants with probable sleep apnea only marginally changed these associations. Self-reported habitual sleep duration was not associated with BMI or obesity., Conclusions: Sleep duration, as measured with actigraphy, had a U-shaped relationship with BMI and obesity in an elderly population. A highly fragmented sleep is associated with a higher BMI and a higher risk of obesity, and may explain why short sleep is related to obesity. To preclude bias that can be introduced by self-report measures of sleep duration, using multiple measures of sleep parameters is recommended in future research.

Several large studies have shown that both short and long average sleep durations increase the risk of hypertension in adults. We investigated whether sleep duration is also associated with hypertension in the elderly. This cross-sectional study was conducted in 5058 participants of the population-based Rotterdam Study, aged 58 to 98 years. Blood pressure was measured at the research center. Hypertension was defined as a systolic blood pressure of >or=160 mm Hg and/or a diastolic blood pressure of >or=100 mm Hg or current use of antihypertensive medication. In all of the participants, sleep duration was assessed by self-report. In a subsample of 975 subjects, it was additionally measured with actigraphy, a validated method that infers wakefulness and sleep from the presence or absence of limb movement. After adjustment for age and gender and additionally for body mass index, smoking, depressive symptoms, sleep medication use, diabetes mellitus, myocardial infarction, and stroke, none of the odds ratios (varying from 0.54; 95% CI: 0.27 to 1.08; to 1.19; 95% CI: 0.89 to 1.58) reflected a significant association between sleep duration and hypertension, whether measured by self-report or actigraphy. This study strongly suggests that sleep duration is not associated with hypertension in the elderly.

Background: The Schedules for Clinical Assessment in Neuropsychiatry (SCAN), the successor of the ninth version of the Present State Examination (PSE-9), is one of the latest instruments developed by the World Health Organisation for the assessment of psychiatric disorders. So far, the psychometric properties have only been established for certain sections of the instrument. The present study is the first to test the psychometric properties of SCAN-2.1 for most of the disorders covered by the SCAN, and was carried out prior to a survey conducted in the Nijmegen Health Area (the Netherlands)., Methods: Interviewers were psychology graduates with little clinical experience. Two designs were used. In one design, pairs of independent live interviews with the same respondent were compared (test-retest situation). In the other, ten videotaped interviews by experts were rated by each of the interviewers (standardized situation), and the outcomes were compared with those of the other interviewers as well as with a reference score., Results: In the test-retest situation the kappa coefficient for diagnostic caseness was qualified as substantial (0.62) and for diagnostic categories and diagnostic groups as moderate to good (0.24 to 0.64). In the standardized situation using videotaped interviews by experts, sensitivity as well as specificity proved to be substantial to almost perfect. The agreement per interviewer with regard to the reference diagnoses ranged from 87% (diagnostic group) to 94% (diagnostic caseness). Agreement on the syndrome level (without duration and interference criteria of DSM-IV) was excellent., Conclusions: Although the instrument is traditionally used by experienced clinicians, this study shows that less experienced (but well trained) interviewers can apply SCAN reliably. Special attention should be paid to the items without explicit interview questions, as they tend to be more sensitive to neglect than the items with interview questions.

In this study we estimated the prevalence of dementia, affective and anxiety disorders among residents of homes for the elderly in Amsterdam. Of a sample of 3.828 residents, 954 persons were interviewed with the Mini-Mental State Examination (MMSE) and the Center for Epidemiologic Studies Depression Scale; 324 were additionally interviewed with the Diagnostic Interview Scheme (DIS). The prevalence of dementia and of affective- and anxiety disorders is estimated to be 12.0% and 16.8%, respectively. These estimates, however, should be interpreted with caution. Analyses of the non-response group showed that about one-fourth of those who did not or could not participate in the study showed signs of dementia or other psychiatric problems. Although mental health care in homes for the elderly is underdeveloped, it should be an integral part of its health care delivery.
