Care-Seeking Pattern among Persons with Depression and Anxiety: A Population-Based Study in Sweden

Background. In primary care, a vast majority of patients affected with depression and anxiety present with somatic symptoms. Detection rate of psychiatric symptoms is low, and knowledge of factors influencing care seeking in persons affected by depressive and anxiety disorders on a population level is limited. Objective. This study aims to describe if persons, affected by depression and anxiety disorders, seek care and which type of care they seek as well as factors associated with care seeking. Method. Data derives from a longitudinal population-based study of mental health conducted in the Stockholm County in 1998–2010 and the present study includes 8387 subjects. Definitions of anxiety and depressive disorders were made according to DSM-IV criteria, including research criteria, using validated diagnostic scales. 2026 persons (24%) fulfilled the criteria for any depressive or anxiety disorder. Results. Forty-seven percent of those affected by depression and/or anxiety had been seeking care for psychological symptoms within the last year. A major finding was that seeking care for psychological symptoms was associated with having treatment for somatic problems. Conclusions. As a general practitioner, it is of great importance to increase awareness of mild mental illness, especially among groups that might be less expected to be affected

Association of Catechol-Omethyltransferase (COMT Val158Met) with future risk of cardiovascular disease in depressed individuals - a Swedish population-based cohort study

Background: Catechol-O-methyltransferase (COMT Val158Met) has been implicated in both depression and cardiovascular disease. The purpose of this study was to assess if COMT Val158Met, which influences the COMT enzyme activity, has an effect on the risk of cardiovascular disease (CVD) in individuals with a history of depression and also to determine if the risk differs depending on gender. Methods: Data from a longitudinal cohort study of mental health among Swedish adults was used. Depression was assessed twice 3 years apart for each participant, in 1998-2001 and 2001-2003. Saliva DNA was contributed by 4349 (41.7%) of the participants and 3525 was successfully genotyped for COMT Val158Met. Participants were followed up until December 2014 from the National Patient register with regard to cardiovascular outcomes (hypertensive or ischemic heart disease, and stroke). Results: Those with depression and the high COMT enzyme activity genotype (Val/Val) had almost a three-fold increased risk of later CVD (OR 3.6; 95% CI: 2.0-6.6) compared to those non-depressed carrying the Val/Val allele. This effect on risk for CVD was higher in women compared to men (OR 7.0; 95% CI: 3.0-14.0 versus OR 2.1; 95% CI: 1.0-6.8). Both additive interaction (attributable proportion (AP) = 0.56; 95% CI: 0.24-0.90 and synergy index (SI) = 4.39; 1.0-18.7) and multiplicative interaction (log likelihood test p = 0.1) was present between depression and COMT Val158Met in predicting risk of later CVD. Conclusion: High COMT activity genotype Val158Met increased the risk of CVD in depressed persons. The risk was higher in women compared to men

Long-term stability in obsessive thoughts and compulsive behavior in the general population: a longitudinal study in Sweden

OBJECTIVE: Obsessive thoughts and compulsive behavior and their related disorder Obsessive-Compulsive Disorder (OCD) commonly occur in the general population. Clinical populations indicate a high level of stability, although there are few longitudinal studies in the general population. The recommended drug treatments are SSRIs/TCAs. However, there are few long-term follow up studies. The goal of this study was to 1) examine the occurrence and stability of obsessions, compulsions, and OCD in a longitudinal population-based survey, 2) investigate the use of SSRI and TCA and the potential effect on symptoms. METHODS: A ten-year longitudinal general population in Stockholm was used (2000 and 2010, n = 5650) Obsessional washing, checking, intrusive unpleasant thoughts and the level of suffering due to these symptoms were measured by self-report. Information on use of SSRIs and TCAs by these individuals was obtained from registers. Stability was examined using contingency tables and multinomial logistic regression. RESULTS: At baseline, 2.1, 11.7 and 11.9% reported obsessional washing, checking and intrusive thoughts. A total of 5% reported considerable suffering from these (i.e. OCD). Based on psychiatric interview only 0.4% had OCD. Ten years later a quarter of OCD cases were still classified as having OCD, one quarter reported any obsessive or compulsive symptom and half were classified as symptom-free. Treatment receipt was low and controlling for medication did not change the stability. CONCLUSION: Obsessive thoughts and compulsive behavior are common and stable. While this group is potentially undertreated, there is no indication that those treated display a different pattern of recovery

Cortisol Concentration as Predictor of Tobacco Initiation in Adolescents: Results From a Population-Based Swedish Cohort.

Abstract Purpose Stress potentiates the smoking reward, decreases the ability to resist smoking, and increases the risk of smoking relapse in adulthood. This study aimed to clarify if salivary cortisol, as an indicator of stress, may be prospectively associated with the onset and phenotype of tobacco use in adolescents. Methods This study was based on a cohort of Swedish adolescents, among whom saliva specimens were collected from a nested sample. We included adolescents with salivary cortisol measurements and without a history of tobacco use (n = 381, aged 13–14 years). Quartiles of morning and afternoon cortisol concentration and cortisol area under the curve were considered as predictors. We categorized tobacco use according to the product mainly used: cigarette smoking, snus use, or either type of tobacco. For each product use, two outcomes were considered: initiation and duration of use. Poisson regression models were used to calculate rate ratios. Results A quartile increase in morning cortisol levels and cortisol area under the curve was consistently associated with a 1.2- to 1.4-fold increased risk of initiation of cigarette smoking snus use, or any tobacco use. Similar results were obtained examining the dose–response relationship and using the duration of use as outcome. No associations were apparent between afternoon cortisol concentration and any of the outcomes. All associations were similar between sexes. Conclusions Morning cortisol concentration, an indicator of hypothalamic–pituitary–adrenal axis activation, is prospectively associated with tobacco use in adolescents. Whether this activation indicates the cumulative effect of stressors during the life course remains to be elucidated

No association of cigarette smoking and depressive symptoms with cortisol concentration in adolescents. Results from a population-based Swedish cohort.

Several studies have shown that smoking increases the risk of depressive symptoms, and suggested a possible role of the hypothalamic-pituitary-adrenal axis in the smoking-depression pathway. This study aimed to assess if smokers have higher cortisol levels than non-smokers, and if higher cortisol levels are associated with depressive symptoms. Saliva samples were collected from a subgroup of 409 participants at enrolment (13-14 years old) and two years later (15-16 years old). First, we examined the association between smoking phenotypes and cortisol concentration. Second, we evaluated whether these associations differed between adolescents with and without depressive symptoms. The mean difference between smokers and non-smokers in cortisol concentrations was close to zero at both time points. For instance, the adjusted mean difference for morning cortisol concentration between current and non-current smokers was 0.000 µg/dl [95% CI -0.055, 0.056]. In addition, there were no differences in cortisol concentration at the second time-point between those who had smoked and those who did not during the two previous years. Moreover, cortisol levels were not associated with depressive symptoms. The hypothesis that dysregulation of the hypothalamic-pituitary-adrenal axis might be involved in the association between smoking behavior and depressive symptoms during adolescence was not supported by this data

Implementing clinical quidelines in psychiatry : a qualitative study of perceived facilitators and barriers

BACKGROUND: Translating scientific evidence into daily practice is complex. Clinical guidelines can improve health care delivery, but there are a number of challenges in guideline adoption and implementation. Factors influencing the effective implementation of guidelines remain poorly understood. Understanding of barriers and facilitators is important for development of effective implementation strategies. The aim of this study was to determine perceived facilitators and barriers to guideline implementation and clinical compliance to guidelines for depression in psychiatric care. METHODS: This qualitative study was conducted at two psychiatric clinics in Stockholm, Sweden. The implementation activities at one of the clinics included local implementation teams, seminars, regular feedback and academic detailing. The other clinic served as a control and only received guidelines by post. Data were collected from three focus groups and 28 individual, semi-structured interviews. Content analysis was used to identify themes emerging from the interview data. RESULTS: The identified barriers to, and facilitators of, the implementation of guidelines could be classified into three major categories: (1) organizational resources, (2) health care professionals' individual characteristics and (3) perception of guidelines and implementation strategies. The practitioners in the implementation team and at control clinics differed in three main areas: (1) concerns about control over professional practice, (2) beliefs about evidence-based practice and (3) suspicions about financial motives for guideline introduction.Peer reviewe

Supported local implementation of clinical guidelines in psychiatry: a two-year follow-up

BACKGROUND: The gap between evidence-based guidelines for clinical care and their use in medical settings is well recognized and widespread. Only a few implementation studies of psychiatric guidelines have been carried out, and there is a lack of studies on their long-term effects.The aim of this study was to measure compliance to clinical guidelines for treatment of patients with depression and patients with suicidal behaviours, two years after an actively supported implementation. METHODS: Six psychiatric clinics in Stockholm, Sweden, participated in an implementation of the guidelines. The guidelines were actively implemented at four of them, and the other two only received the guidelines and served as controls. The implementation activities included local implementation teams, seminars, regular feedback, and academic outreach visits. Compliance to guidelines was measured using quality indicators derived from the guidelines. At baseline, measurements of quality indicators, part of the guidelines, were abstracted from medical records in order to analyze the gap between clinical guidelines and current practice. On the basis of this, a series of seminars was conducted to introduce the guidelines according to local needs. Local multidisciplinary teams were established to monitor the process. Data collection took place after 6, 12, and 24 months and a total of 2,165 patient records were included in the study. RESULTS: The documentation of the quality indicators improved from baseline in the four clinics with an active implementation, whereas there were no changes, or a decline, in the two control clinics. The increase was recorded at six months, and persisted over 12 and 24 months. CONCLUSIONS: Compliance to the guidelines increased after active implementation and was sustained over the two-year follow-up. These results indicate that active local implementation of clinical guidelines involving clinicians can change behaviour and maintain compliance.Peer reviewe

Early exposure to antibiotic drugs and risk for psychiatric disorders: a population-based study

Early life exposure to infection, anti-infectives and altered immune activity have been associated with elevated risk of some psychiatric disorders. However, the risk from exposure in fetal life has been proposed to be confounded by familial factors. The hypothesis of this study is that antibiotic drug exposure during the fetal period and the first two postnatal years is associated with risk for later development of psychiatric disorders in children. All births in Finland between 1996 and 2012, 1 million births, were studied for antibiotic drug exposure: mothers during pregnancy and the children the first two postnatal years. The children were followed up for a wide spectrum of psychiatric diagnoses and psychotropic drug treatment until 2014. Cox proportional hazards modeling was used to estimate effects of antibiotic drug exposure on offspring psychiatric disorders. Modestly (10–50%) increased risks were found on later childhood development of sleep disorders, ADHD, conduct disorder, mood and anxiety disorders, and other behavioral and emotional disorders with childhood onset (ICD-10 F98), supported by increased risks also for childhood psychotropic medication. The prenatal exposure effects detected were not explained by explored familial confounding, nor by registered maternal infections. To conclude, this longitudinal nation-wide study shows that early life antibiotic drug exposure is associated with an increased risk for childhood development of psychopathology. Given the high occurrence of early-life antibiotic exposure, these findings are of public health relevance. Whether the associations reflect effects of the antibiotic drug use or of the targeted infections remains to be explored further.</p

CRY2 Is Associated with Depression

Abnormalities in the circadian clockwork often characterize patients with major depressive and bipolar disorders. Circadian clock genes are targets of interest in these patients. CRY2 is a circadian gene that participates in regulation of the evening oscillator. This is of interest in mood disorders where a lack of switch from evening to morning oscillators has been postulated.We observed a marked diurnal variation in human CRY2 mRNA levels from peripheral blood mononuclear cells and a significant up-regulation (P = 0.020) following one-night total sleep deprivation, a known antidepressant. In depressed bipolar patients, levels of CRY2 mRNA were decreased (P = 0.029) and a complete lack of increase was observed following sleep deprivation. To investigate a possible genetic contribution, we undertook SNP genotyping of the CRY2 gene in two independent population-based samples from Sweden (118 cases and 1011 controls) and Finland (86 cases and 1096 controls). The CRY2 gene was significantly associated with winter depression in both samples (haplotype analysis in Swedish and Finnish samples: OR = 1.8, P = 0.0059 and OR = 1.8, P = 0.00044, respectively).We propose that a CRY2 locus is associated with vulnerability for depression, and that mechanisms of action involve dysregulation of CRY2 expression
