One-month prevalence of mental disorders in the United States and sociodemographic characteristics: the Epidemiologic Catchment Area study

Unpredictable neonatal stress enhances adult anxiety and alters amygdala gene expression related to serotonin and GABA

Anxiety-related disorders are among the most common psychiatric illnesses, thought to have both genetic and environmental causes. Early-life trauma, such as abuse from a caregiver, can be predictable or unpredictable, each resulting in increased prevalence and severity of a unique set of disorders. In this study, we examined the influence of early unpredictable trauma on both the behavioral expression of adult anxiety and gene expression within the amygdala. Neonatal rats were exposed to unpaired odor-shock conditioning for 5 days, which produces deficits in adult behavior and amygdala dysfunction. In adulthood, we used the Light/Dark box test to measure anxiety-related behaviors, measuring the latency to enter the lit area and quantified urination and defecation. The amygdala was then dissected and a microarray analysis was performed to examine changes in gene expression. Animals that had received early unpredictable trauma displayed significantly longer latencies to enter the lit area and more defecation and urination. The microarray analysis revealed over-represented genes related to learning and memory, synaptic transmission and trans-membrane transport. Gene ontology and pathway analysis identified highly represented disease states related to anxiety phenotypes, including social anxiety, obsessive-compulsive disorders, post-traumatic stress disorder and bipolar disorder. Addiction-related genes were also overrepresented in this analysis. Unpredictable shock during early development increased anxiety-like behaviors in adulthood with concomitant changes in genes related to neurotransmission, resulting in gene expression patterns similar to anxiety-related psychiatric disorders.

Poststroke Anxiety is Prevalent at the Population Level, Especially among Socially Deprived and Younger Age Community Stroke Survivors

Background

Most studies of poststroke anxiety prevalence are hospital based, so knowledge of anxiety in community stroke survivors is limited. Few studies address the association between poststroke anxiety and patient age. No study has explored the relationship between poststroke anxiety prevalence and social deprivation.

Aims

This study aims to describe population level prevalence data of poststroke anxiety and to explore association of poststroke anxiety prevalence with patient age, gender, and social deprivation.

Methods

Observational study of 3831 community stroke survivors attending general practice reviews from April 1, 2009 to March 31, 2010 in Greater Glasgow, United Kingdom. Univariate and multivariate analyses investigated the association between poststroke anxiety prevalence (Hospital Anxiety and Depression Scale: anxiety sub-scale [HADS-A]), age, gender, and deprivation variables.

Results

Six hundred eighteen (16·1%) of 3831 community-dwelling stroke survivors had definite abnormal mood on HADS-A (≥11), with 952 (31·5%) scoring ≥8. Sixty-five (35·5%) of stroke survivors aged under 50 years had definite abnormal mood on HADS-A compared with 59 (7·2%) of over 80 year olds. Three hundred forty (19·8%) of women had definite abnormal mood on HADS-A compared with 278 (13·1%) of men. Three hundred seventy-two (22·6%) of most deprived stroke survivors had definite abnormal mood on HADS-A compared with 49 (7·6%) of least deprived. Age, gender, and social deprivation all contributed significantly to HADS-A score variance.

Conclusion

Using a conservative HADS-A cutoff, a high prevalence of definite abnormal anxiety in community stroke survivors is observed. This prevalence increases markedly in younger and more socially deprived stroke survivors.

Unique and related predictors of major depressive disorder, posttraumatic stress disorder, and their comorbidity after Hurricane Katrina

The current study examined demographic and psychosocial factors that predict major depressive disorder (MDD) and comorbid MDD/posttraumatic stress disorder (MDD/PTSD) diagnostic status after Hurricane Katrina, one of the deadliest and costliest hurricanes in the history of the United States. This study expanded on the findings published in the article by Galea, Tracy, Norris, and Coffey (J Trauma Stress 21:357-368, 2008), which examined the same predictors for PTSD, to better understand related and unique predictors of MDD, PTSD, and MDD/PTSD comorbidity. A total of 810 individuals representative of adult residents living in the 23 southernmost counties of Mississippi before Hurricane Katrina were interviewed. Ongoing hurricane-related stressors, low social support, and hurricane-related financial loss were common predictors of MDD, PTSD, and MDD/PTSD, whereas educational and marital status emerged as unique predictors of MDD. Implications for postdisaster relief efforts that address the risk for both MDD and PTSD are discussed.

Mental disorders in primary care in Israel: prevalence and risk factors

OBJECTIVE

Psychiatric morbidity is common among patients in primary care services and leads to disability and increased use of medical services. Comparison of primary care and community prevalence data is of interest in relation to the health services planning for mental disorders. The aim of the present study was to measure prevalence of mental disorders in six primary care clinics in Israel and to assess risk factors for these disorders.

METHOD

Prevalence of mental disorders was measured in a sample of 2,948 primary care consecutive attendees, using two-stage stratified sampling with the General Health Questionnaire 12 (GHQ-12) and the Composite International Diagnostic Interview (CIDI).

RESULTS

A high rate (46.3%) of current mental disorders was found, with rates of current depressive episode, generalized anxiety disorder, somatization disorder, and neurasthenia being relatively high in comparison with rates in other countries. Low education was a risk factor for all categories of disorders, unemployment a risk factor for depressive disorders, and parenthood was protective for most categories of disorders.

CONCLUSIONS

High rates of mental disorders were found in this Israeli primary care sample as compared to other countries, while in the community the rates were midrange as compared to other countries, pointing to a relatively higher use of primary care services by patients with mental disorders in Israel than in other countries.

Lifetime manic spectrum episodes and all-cause mortality: 26-year follow-up of the NIMH Epidemiologic Catchment Area Study

BACKGROUND

While evidence suggests that depression is associated with medical morbidity and mortality, the potential role of mania has received less attention. This analysis evaluated the association between manic spectrum episodes and risk of all-cause mortality over a 26-year follow-up in a population-based study.

METHODS

Participants included 14,870 adults (mean age 48.2 ± 20.3; 58.2% female; 31.1% non-white) from four sites of the Epidemiologic Catchment Area Study who completed the Diagnostic Interview Schedule (DIS) mania assessment between 1980 and 1983 and had vital status data available through 2007. Participants were grouped into four mutually exclusive categories based on DIS mania assessment: (1) manic episode (n=46); (2) hypomanic episode (n=195); (3) sub-threshold manic symptoms (n=1041); and (4) no manic spectrum episodes (n=13,588). To determine vital status, participants were matched with the National Death Index. Participants with manic spectrum episodes were compared to those without such episodes with regard to mortality after 26 years.

RESULTS

After adjusting for major depressive symptoms and demographic differences, odds of mortality at follow-up for participants with lifetime manic spectrum episodes in the 30-44 and 45-64 year age cohorts at baseline were higher than those with no lifetime manic spectrum episodes in the same age cohorts (OR=1.39, 95% CI=[1.00, 1.93] and OR=1.41, 95% CI=[1.02, 1.95] respectively).

CONCLUSIONS

History of lifetime manic spectrum episodes in early to mid adulthood is associated with increased risk of all-cause mortality in mid to late life.

LIMITATIONS

Future studies of mania and mortality should evaluate specific causes of mortality.

Do psychiatric disorders continue during pregnancy in women with hyperemesis gravidarum: a prospective study

OBJECTIVE

We aimed to determine Axis I psychiatric disorders in women with hyperemesis gravidarum (HG) and to follow up the course of psychiatric disorder and its association with nausea and vomiting (NV) during pregnancy.

METHODS

The study sample was composed of 47 patients with HG. Psychiatric interviews were conducted using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID-I). Other psychiatric interviews were performed in the second and third trimesters. On each visit, the subjects completed the Beck Depression Inventory and the Beck Anxiety Inventory.

RESULTS

The prevalence of any anxiety disorder was 25.5%, and the prevalence of any mood disorder was 14.9% in women with HG in the first trimester. Psychiatric disorders continued throughout the pregnancy in two thirds of the women who had HG and a psychiatric diagnosis. Any SCID diagnosis in the first trimester was higher in women whose NV had partially resolved than in women whose NV had fully resolved (P<.05).

CONCLUSION

The present studies suggest that psychiatric disorders may play a significant role in the etiology of HG. Our findings presented a potential connection between HG and anxiety disorders and major depressive disorder. Additionally, the NV symptoms in women with HG and a psychiatric disorder may persist during pregnancy.

Implementing the World Mental Health Survey Initiative in Portugal - rationale, design and fieldwork procedures

BACKGROUND

The World Mental Health Survey Initiative was designed to evaluate the prevalence, the correlates, the impact and the treatment patterns of mental disorders. This paper describes the rationale and the methodological details regarding the implementation of the survey in Portugal, a country that still lacks representative epidemiological data about psychiatric disorders.

METHODS

The World Mental Health Survey is a cross-sectional study with a representative sample of the Portuguese population, aged 18 or older, based on official census information. The WMH-Composite International Diagnostic Interview, adapted to the Portuguese language by a group of bilingual experts, was used to evaluate the mental health status, disorder severity, impairment, use of services and treatment. Interviews were administered face-to-face at respondent's dwellings, which were selected from a nationally representative multi-stage clustered area probability sample of households. The survey was administered using computer-assisted personal interview methods by trained lay interviewers. Data quality was strictly controlled in order to ensure the reliability and validity of the collected information.

RESULTS

A total of 3,849 people completed the main survey, with 2,060 completing the long interview, with a response rate of 57.3%. Data cleaning was conducted in collaboration with the WMHSI Data Analysis Coordination Centre at the Department of Health Care Policy, Harvard Medical School. Collected information will provide lifetime and 12-month mental disorders diagnoses, according to the International Classification of Diseases and to the Diagnostic and Statistical Manual of Mental Disorders.

CONCLUSIONS

The findings of this study could have a major influence in mental health care policy planning efforts over the next years, specially in a country that still has a significant level of unmet needs regarding mental health services organization, delivery of care and epidemiological research.

Mood and anxiety disorders among inpatients of a university hospital in Turkey

OBJECTIVE

The aim of the study was to assess the prevalence of mood and anxiety disorders among inpatients and the relationship between sociodemographic factors, medical illnesses and treatments.

METHODS

In the present study, we selected 650 inpatients from all clinics except psychiatry and pediatrics in a general hospital by a simple random sampling method. Based on the exclusion criteria, 57 patients were excluded. Mood and anxiety disorders were determined by means of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition.

RESULTS

Of the participants, 226 (37.5%) had a psychiatric disorder, 87 (14.4) had a mood disorder and 146 (24.2%) had an anxiety disorder. The most common specific diagnoses were not otherwise specified as anxiety disorder (9.5%), major depression (8.6%) and generalized anxiety disorder (7.6%). While the overall prevalence was highest in the hematology clinic (60.0%), it was lowest in the clinic of infectious diseases (22.7%). Logistic regression analysis indicated that the independent factors associated with psychiatric disorders were being of the female gender and a personal history of psychiatric disorders.

CONCLUSIONS

In conclusion, results of the present study suggest that mood and anxiety disorders were frequently observed among inpatients, particularly in female patients and those with an individual history of psychiatric disorder. Successful treatment of these disorders may positively contribute to the course of the disease in inpatients. However, this assumption should be confirmed by further studies.

Altered Wnt signalling in the teenage suicide brain: focus on glycogen synthase kinase-3β and β-catenin

Glycogen synthase kinase (GSK)-3β and β-catenin are important components of the Wnt signalling pathway, which is involved in numerous physiological functions such as cognition, brain development and cell survival. Their abnormalities have been implicated in mood disorders and schizophrenia. Teenage suicide is a major public health concern; however, very little is known about its neurobiology. In order to examine if abnormalities of GSK-3β and β-catenin are associated with teenage suicide, we determined the gene and protein expression of GSK-3β and β-catenin in the prefrontal cortex (PFC) and hippocampus obtained from 24 teenage suicide victims and 24 normal control subjects. Protein expression was determined using Western blot with specific antibodies and gene expression (mRNA levels) was determined using the real-time polymerase chain reaction method. No significant change was observed in the GSK-3β protein levels either in the PFC or hippocampus of suicide victims compared to controls. However, protein levels of pGSK-3β-ser(9) were significantly decreased in the PFC and hippocampus of suicide victims compared to normal controls. We also found that GSK-3β mRNA levels were significantly decreased in the PFC but not in the hippocampus of teenage suicide victims compared to controls. Mean protein and mRNA levels of β-catenin were significantly decreased in both the PFC and hippocampus of teenage suicide group compared to controls. The observation that there is a decrease in β-catenin and pGSK-3β-ser(9) in the PFC and hippocampus of teenage suicide victims does indicate a disturbance in the Wnt signalling pathway in teenage suicide.

Relationship quality and levels of depression and anxiety in a large population-based survey

PURPOSE

There is substantial literature suggesting that the mental health benefits of marriage (compared to being single) are greater for those in 'good-quality' relationships in comparison to those in 'poor-quality' relationships. However, little of this research utilises large population-based surveys. Large surveys in psychiatric epidemiology have focused almost exclusively on the association between marital status and mental health. The current study explores some of the reasons for this gap in the literature, and adopts a large, representative community-based sample to investigate whether associations between relationship status and levels of depression and anxiety are moderated by relationship quality.

METHODS

Participants were from Wave 3 of the PATH Survey, a longitudinal community survey assessing the health and well-being of residents of the Canberra region, Australia (n = 3,820). Relationship quality was measured using the 7 item dyadic adjustment scale (DAS-7), and levels of depression and anxiety were measured using the Goldberg scales.

RESULTS

Both cross-sectional and prospective analyses showed that associations between relationship status and mental health were moderated by relationship quality for both men and women, such that only good-quality relationships bestowed mental health benefits over remaining single. For women, being in a poor-quality relationship was associated with greater levels of anxiety than being single.

CONCLUSIONS

Epidemiological studies need to measure relationship quality to qualify the effect of relationship status on mental health.

Obsessive and compulsive symptoms in a national sample of older people: prevalence, comorbidity, and associations with cognitive function

OBJECTIVES

To describe the prevalence of obsessive and compulsive symptoms in a national community sample of older adults, their comorbidity with mental disorders, and associations with cognitive impairment.

DESIGN

A secondary analysis of data from a national survey.

SETTING

The 2000 British National Psychiatric Morbidity Survey.

PARTICIPANTS

Primary analyses focused on 2,007 60- to 74-year-old community residents; secondary analyses compared these with 6,573 younger survey participants age 16-59 years.

MEASUREMENTS

Obsessive and compulsive symptoms and mental disorders, including International Classification of Diseases, Tenth Revision (ICD-10) obsessive-compulsive disorder, were ascertained from the revised Clinical Interview Schedule and cognitive function from the modified Telephone Interview for Cognitive Status (global function, immediate and delayed word recall), verbal fluency (animal naming), and National Adult Reading Test (estimated verbal IQ). Health-related quality of life (SF12) was measured in addition to subjective impact.

RESULTS

One-month prevalences of obsessive and compulsive symptoms and obsessive-compulsive disorder were 4.7%, 2.2%, and 0.4%, respectively (compared with 5.9%, 3.2%, and 0.8% in younger participants). High levels of comorbidity were found. Obsessive and compulsive symptoms were described as distressing by 67.8% and 70.2%, respectively, and both were associated with worse mental health-related quality of life. Obsessive symptoms were associated with lower verbal IQ and also with lower verbal fluency, which was not accounted for by education or estimated verbal IQ.

CONCLUSIONS

Obsessions and compulsions had significant prevalence in this national older population. Consistent with previous reports, relative impairment in executive function (verbal fluency) was found in people reporting these symptoms.

The prevalence of mental disorders in older people in Western countries - a meta-analysis

OBJECTIVE

To conduct a meta-analysis assessing the prevalence of mental disorders in older people in Europe and North America.

METHOD

Studies that reported prevalence rates of mental disorders in older people from the general population were identified through MEDLINE, PsycINFO, Web of Science, and reference lists for the period between January 2000 and December 2011. Studies were included if they reported prevalence rates of mental disorders in older people (50+ years) from the community. The final sample comprised 25 studies. Prevalence rates were extracted, and effect sizes were transformed into logits. Random-effects models were calculated due to significant heterogeneity. In meta-regression analyses possible sources of bias, including age of onset, gender distribution, and risk of bias were examined. To analyze the robustness of the results, sensitivity analyses were performed. Publication bias was assessed with funnel plots and the Egger method.

RESULTS

Disorders with the highest prevalence estimates were dimensional depression (19.47%), lifetime major depression (16.52%), and lifetime alcohol use disorders (11.71%). Disorders with the lowest estimates were current and lifetime drug use disorders (0.34% and 0.19%, respectively), and current bipolar disorder and current agoraphobia (both 0.53%).

CONCLUSION

The majority of studies investigated major depression, panic disorder and social phobia. Future research requires a larger database on the epidemiology of mental disorders in the elderly. Furthermore, an improvement to the methodology that addresses the challenges of older age and produces comparable data, including the use of instruments tailored to the needs of older people, is required.

Childhood adversities and adult-onset asthma: a cohort study

OBJECTIVES

Childhood adversities may be important determinants of later illnesses and poor health behaviour. However, large-scale prospective studies on the associations between childhood adversities and the onset of asthma in adulthood are lacking.

DESIGN

Prospective cohort study with 7-year follow-up.

SETTING

Nationally representative study. Data were collected from the Health and Social Support (HeSSup) survey and national registers.

PARTICIPANTS

The participants represent the Finnish population from the following age groups: 20-24, 30-34, 40-44, and 50-54 years at baseline in 1998 (24 057 survey participants formed the final cohort of this study). The occurrence of childhood adversities was assessed at baseline with a six-item survey scale. The analyses were adjusted for sociodemographic characteristics, behavioural health risks and common mental disorders.

PRIMARY AND SECONDARY OUTCOMES

The survey data were linked to data from national health registers on incident asthma during a 7-year follow-up to define new-onset asthma cases with verified diagnoses.

RESULTS

A total of 12 126 (59%) participants reported that they encountered a childhood adversity. Of them 3677 (18% of all) endured three to six adversities. During a follow-up of 7 years, 593 (2.9%) participants were diagnosed with incident asthma. Those who reported three or more childhood adversities had a 1.6-fold (95% CI 1.31 to 2.01) greater risk of asthma compared to those without childhood adversities. This hazard attenuated but remained statistically significant after adjustment for conventional risk factors (HR 1.33; 95% CI 1.06 to 1.67).

CONCLUSIONS

Adults who report having encountered adversities in childhood may have an increased risk of developing asthma.

Characteristics of older adults hospitalized in acute psychiatric units in ontario: a population-based study

OBJECTIVE

As the numbers of older adults in Canada increases, there will be a growing need for mental health services for this population. Acute psychiatric units (APUs) provide inpatient psychiatric services for the management of serious mental illness. Understanding the characteristics of older adults in APUs is necessary to determine the range of inpatient services required for this population.

METHOD

We conducted a population-based study of all adults discharged from APUs in Ontario in a 2-year period, 2008-2010, using administrative databases. We compared the characteristics of older adults (aged 66 years and older) in APUs to those of younger adults (aged 18 to 65 years), including sociodemographics, psychiatric and medical diagnoses, and measures of cognition and functioning.

RESULTS

There were a total of 79 352 discharges from APUs, with older adults accounting for 8.8% of all discharges. Depressive disorder was the most common diagnosis, both in older and in younger populations (32.1% and 29.9%, respectively), while dementia accounted for 19.5% of discharges for older adults. Older adults, compared with younger adults, were more likely to have 2 or more chronic medical conditions (83.8% and 20.5%, respectively), significant cognitive impairment (47.0% and 14.5%, respectively), and moderate-to-severe functional impairment (21.8% and 3.3%, respectively).

CONCLUSIONS

Older adults in APUs are a complex group, with mental health and medical care needs that differ from younger adults. APUs must be able to provide adequate psychiatric, medical, and interprofessional services to achieve optimal outcomes. Future studies are required to understand the quality of care and outcomes for older adults in APUs.

Prevalence of psychological distress and associated factors in tuberculosis patients in public primary care clinics in South Africa

BACKGROUND

Psychological distress has been rarely investigated among tuberculosis patients in low-resource settings despite the fact that mental ill health has far-reaching consequences for the health outcome of tuberculosis (TB) patients. In this study, we assessed the prevalence and predictors of psychological distress as a proxy for common mental disorders among tuberculosis (TB) patients in South Africa, where over 60 % of the TB patients are co-infected with HIV.

METHODS

We interviewed 4900 tuberculosis public primary care patients within one month of initiation of anti-tuberculosis treatment for the presence of psychological distress using the Kessler-10 item scale (K-10), and identified predictors of distress using multiple logistic regressions. The Kessler scale contains items associated with anxiety and depression. Data on socio-demographic variables, health status, alcohol and tobacco use and adherence to anti-TB drugs and anti-retroviral therapy (ART) were collected using a structured questionnaire.

RESULTS

Using a cut off score of ≥28 and ≥16 on the K-10, 32.9 % and 81 % of tuberculosis patients had symptoms of distress, respectively. In multivariable analysis older age (OR = 1.52; 95 % CI = 1.24-1.85), lower formal education (OR = 0.77; 95 % CI = 0.65-0.91), poverty (OR = 1.90; 95 % CI = 1.57-2.31) and not married, separated, divorced or widowed (OR = 0.74; 95 % CI = 0.62-0.87) were associated with psychological distress (K-10 ≥28), and older age (OR = 1.30; 95 % CI = 1.00-1.69), lower formal education (OR = 0.55; 95 % CI = 0.42-0.71), poverty (OR = 2.02; 95 % CI = 1.50-2.70) and being HIV positive (OR = 1.44; 95 % CI = 1.19-1.74) were associated with psychological distress (K-10 ≥16). In the final model mental illness co-morbidity (hazardous or harmful alcohol use) and non-adherence to anti-TB medication and/or antiretroviral therapy were not associated with psychological distress.

CONCLUSIONS

The study found high rates of psychological distress among tuberculosis patients. Improved training of providers in screening for psychological distress, appropriate referral to relevant health practitioners and providing comprehensive treatment for patients with TB who are co-infected with HIV is essential to improve their health outcomes. It is also important that structural interventions are promoted in order to improve the financial status of this group of patients.

Is hyperemesis gravidarum associated with mood, anxiety and personality disorders: a case-control study

OBJECTIVE

Intractable nausea and vomiting, known as hyperemesis gravidarum (HG), are relatively common medical problems among pregnant women. Although there are some studies based on psychiatric symptom scales, the relationship between HG and psychiatric disorders, particularly anxiety and personality disorders, is unclear. In this study, we aimed to investigate whether there is a difference among women with and without HG with respect to frequency of mood, anxiety and personality disorders.

METHODS

The study sample was composed of 52 patients with HG and 90 control pregnant women. Mood and anxiety disorders were ascertained by means of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Personality disorders were assessed with the Structured Clinical Interview for DSM, Revised Third Edition, Personality Disorders (SCID-II).

RESULTS

The prevalence of any mood disorder and any anxiety disorder in women with HG was 15.4% and 36.5%, respectively. In addition, 19 (36.5%) of the patients with HG had at least one personality disorder. According to reports collected from the participants in the study, most of the mood or anxiety disorders occurred before the pregnancy in women with HG. The prevalence of major depression, generalized anxiety disorder, avoidant personality disorder and obsessive-compulsive personality disorder was significantly higher in women with HG compared to the control subjects.

CONCLUSIONS

The results of the present study suggest that mood and anxiety disorders, and personality disturbances are frequently observed among women with HG and that there is a potential relationship between these psychiatric disorders and HG during pregnancy.

Correlations between psychological symptoms and social relationships among medical undergraduates in Anhui Province of China

OBJECTIVES

To assess the prevalence of psychological symptoms (depression, anxiety) among Chinese medical students and to find the possible relationships between psychological symptoms and social relationships.

METHODS

A sample of 10,140 medical students was investigated with a structured questionnaire, that included the Beck Depression Inventory, Beck Anxiety Inventory, Social Support Rating Scale, and Family APGAR Index (adaptability, partnership, growth, affection, resolve).

RESULTS

The present study revealed that 16.8% of the medical students suffered from depressive symptoms and 14.1% from anxiety symptoms. Female students were more likely to have anxiety, the second-year students had higher levels of psychological symptoms than the first-year students. Likewise, significant differences were found among college, satisfaction of specialty, and economic condition of the family in anxiety and depression symptoms. Social support, family function, and all dimensions were significantly negatively associated with depression and anxiety symptoms. Multivariable ordinal logistic regression showed that less social support, poor family function, the second-year students, and unsatisfactory specialty were associated with more psychological symptoms, after adjusting the effects of sex, age, and college.

CONCLUSIONS

Medical students have a relatively high level of depression and anxiety symptoms. These findings support the hypothesis that if medical students are better supported and cared for, negative psychosocial consequences might be prevented or at least reduced.

Peyronie's disease in teenagers

INTRODUCTION

Peyronie's disease (PD) is commonly seen in middle-aged men, and little is known about this condition in teenagers.

AIM

To investigate the characteristics of PD in teenagers.

METHODS

The findings were compared between patients with the disease who were teenagers with those over 40 years of age. Statistical analyses were conducted to define differentiating features between these two groups.

MAIN OUTCOME MEASURES

The demographics, clinical features, and associated comorbidities of patients with PD were reviewed.

RESULTS

Thirty-two teenaged males were evaluated for PD in a single institution over a 10-year period. The median age for our cohort was 18 (15-19) years. Forty-five percent of patients had already been seen by another urologist, and 28% had been told they did not have PD. The mean duration of PD before seeking medical care in our cohort was 3 ± 1 months. Sixteen percent of patients reported antecedent penile trauma, half of which happened during coitus or masturbation, and 18% of patients had hemoglobin (Hb) A1c levels > 5%. Dupuytren's contracture was not seen in this population. Twenty-two percent of patients presented with penile pain. Subsequent ED was seen in 37% of patients. Multiple noncontiguous plaques were seen in 37% of patients. Twelve percent were previously treated with vitamin E, while another 12% had previous intralesional verapamil. High distress was reported by 94% of patients. Thirty-four percent sought medical attention for anxiety/mood disorder, and 28% had a negative encounter with a sexual partner related to PD. All of the 32 patients had penile curvature with a mean of 32 ± 12 degrees. Seventy-two percent of the patients had dorsal curvature while 22% had an associated deformity. Using duplex Doppler ultrasound, 12% had a calcified plaque, while none of the patients had abnormal hemodynamics. When compared with PD in adults, teenagers had greater than seven times the prevalence of multiple noncontiguous plaques (37% vs. 5%). Also, the prevalence of HbA1c level > 5% was higher in the teenagers as well (18% vs. 5%).

CONCLUSIONS

PD does occur in teenagers often causing high distress levels. Compared to older adults, teenagers often present earlier, and more commonly have elevated HbA1c level and increased number of plaques at presentation.

Prevalence and related factors of mood and anxiety disorders in a clinical sample of postmenopausal women

PURPOSE

The purpose of the study was to investigate the prevalence and related factors of mood and anxiety disorders in postmenopausal women attending a gynecological outpatient clinic.

METHODS

The study sample included 269 postmenopausal women. The Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, 4th edition was performed to determine the disorders.

RESULTS

Ninety-two (34.2%) women had at least one mood or anxiety disorder. The most common specific disorder was generalized anxiety disorder (15.6%). The existence of any mood or anxiety disorder was associated with poorer economic level.

CONCLUSIONS

Mood and anxiety disorders were frequently observed in postmenopausal women who were admitted to a gynecology outpatient clinic.

Psychiatric disorders and treatment in low-income pregnant women

AIMS

This study estimated the prevalence of twenty-two 12-month and lifetime psychiatric disorders in a sample of 744 low-income pregnant women and the frequency that women with psychiatric disorders received treatment.

METHOD

To identify psychiatric disorders, the Diagnostic Interview Schedule (DIS) was administered to Medicaid or Medicaid-eligible pregnant women enrolled in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC). The sample was stratified by the rural or urban location of the WIC sites in southeastern Missouri and the city of St. Louis. Eligible women were enrolled at each site until their numbers were proportional to the racial distribution of African American and Caucasian pregnant women served there.

RESULTS

The 12-month prevalence of one or more psychiatric disorders was 30.9%. Most common were affective disorders (13.6%), particularly major depressive disorder (8.2%) and bipolar I disorder (5.2%). Only 24.3% of those with a psychiatric disorder reported that they received treatment in the past year. Lifetime prevalence of at least one disorder was 45.6%, with affective disorders being the most frequent (23.5%). Caucasian women were more likely than African Americans to have at least one 12-month disorder, with the difference largely accounted for by nicotine dependence. Higher prevalence of lifetime disorders was also found in Caucasian women, particularly affective disorders and substance use disorders. There were no differences in the prevalence of 12-month or lifetime psychiatric disorders by the urban or rural residence of subjects.

CONCLUSIONS

With nearly one third of pregnant women meeting criteria for a 12-month psychiatric disorder and only one fourth receiving any type of mental health treatment, comprehensive psychiatric screening during pregnancy is needed along with appropriate treatment.

Psychiatric disorders in the elderly

Recent research has shown that depression, anxiety disorders, and psychosis are more common than previously supposed in elderly populations without dementia. It is unclear whether the frequency of these disorders increases or decreases with age. Clinical expression of psychiatric disorders in old age may be different from that seen in younger age groups, with less and often milder symptoms. Concurrently, comorbidity between different psychiatric disorders is immense, as well as comorbidity with somatic disorders. Cognitive function is often decreased in people with depression, anxiety disorders, and psychosis, but whether these disorders are risk factors for dementia is unclear. Psychiatric disorders in the elderly are often related to cerebral neurodegeneration and cerebrovascular disease, although psychosocial risk factors are also important. Psychiatric disorders, common among the elderly, have consequences that include social deprivation, poor quality of life, cognitive decline, disability, increased risk for somatic disorders, suicide, and increased nonsuicidal mortality.

Help-seeking behavior of patients with mental health problems visiting a tertiary care center in north India

BACKGROUND

Patients with mental health problems in the nonwestern world seek help from a variety of sources, such as the family physicians, psychiatrists, psychologists, traditional faith-healers, or alternative medicine practitioners. Understanding the help-seeking behavior is important from the public health perspective.

MATERIALS AND METHODS

Two hundred new patients visiting a psychiatric outpatient service at a tertiary care hospital were interviewed on a semi-structured questionnaire for various services contacted by them for their mental health problems.

RESULTS

Psychiatrists were the first choice in 45% of the cases followed by nonpsychiatric physicians and religious faith healers. Important reasons to seek help from different sources included easy accessibility, belief in the system, or particular healer and good reputation. Mean duration of treatment varied from 2.35 months with the alternative system practitioners to 16.63 months with the psychiatrists. The mean expenditure per visit to a service was highest for the nonpsychiatric physician and lowest for alternative system practitioners.

CONCLUSION

Patients with mental health problems seek help from psychiatrists, nonpsychiatric physicians, faith healers, alternative system practitioners, and traditional faith healers for multiple reasons. It is important to sensitize various nonpsychiatric physicians with early identification and optimum management of mental disorders.

Psychiatric epidemiological surveys in China 1960-2010: how real is the increase of mental disorders?

PURPOSE OF REVIEW

Community psychiatric epidemiological surveys over the last five decades have revealed a dramatic increase in the prevalence of mental disorders in China. This article summarizes the main surveys and attempts to interpret the increase of prevalence from a methodological perspective.

RECENT FINDINGS

Regional and national surveys conducted in China during 1960-1990 focused on severe mental disorders and revealed very low and stable rates of disorders. By contrast, those performed in the last decade, whether psychiatrists or lay interviewers were used, have shown much higher and more 'reliable' rates comparable to those found in high-income countries. This is especially so for depression and anxiety disorders.

SUMMARY

Given the sociopolitical turmoil that had previously plagued people in China, the dramatic rise in prevalence estimates of mental disorders in recent years cannot be simply interpreted as a substantive deterioration of mental health following rapid social change. Global and local factors that shape research methodology aimed at showing that mental disorders are common may play an important role in the dramatic increase. Future research in China should move beyond descriptive epidemiology. It should also address policy relevant issues in view of the limited resources available for mental health interventions.

Designing personalized treatment engagement interventions for depressed older adults

Despite the benefits of treatment for late-life depression, underutilization of mental health services by older adults and nonadherence to offered interventions exist. This article describes psychosocial and interactional barriers and facilitators of treatment engagement among depressed older adults served by community health care settings. The authors describe the need to engage older adults in treatment using interventions that: (1) target psychological barriers such as stigma and other negative beliefs about depression and its treatment; and (2) increase individuals' involvement in the treatment decision-making process. Personalized treatment engagement interventions designed by the authors' group for various community settings are presented.

Brazilian psychiatric brain bank: a new contribution tool to network studies

There is an urgent need for expanding the number of brain banks serving psychiatric research. We describe here the Psychiatric Disorders arm of the Brain Bank of the Brazilian Aging Brain Study Group (Psy-BBBABSG), which is focused in bipolar disorder (BD) and obsessive compulsive disorder (OCD). Our protocol was designed to minimize limitations faced by previous initiatives, and to enable design-based neurostereological analyses. The Psy-BBBABSG first milestone is the collection of 10 brains each of BD and OCD patients, and matched controls. The brains are sourced from a population-based autopsy service. The clinical and psychiatric assessments were done by an expert team including psychiatrists, through an informant. One hemisphere was perfused-fixed to render an optimal fixation for conducting neurostereological studies. The other hemisphere was comprehensively dissected and frozen for molecular studies. In 20 months, we collected 36 brains. A final report was completed for 14 cases: 3 BDs, 4 major depressive disorders, 1 substance use disorder, 1 mood disorder NOS, 3 obsessive compulsive spectrum symptoms, 1 OCD and 1 schizophrenia. The majority were male (64%), and the average age at death was 67.2 ± 9.0 years. The average postmortem interval was 16 h. Three matched controls were collected. The pilot stage confirmed that the protocols are well fitted to reach our goals. Our unique autopsy source makes possible to collect a fairly number of high quality cases in a short time. Such a collection offers an additional to the international research community to advance the understanding on neuropsychiatric diseases.

Development and validation of a 6-day standard for the identification of frequent mental distress

PURPOSE

The goals of the current study were to assess the concurrent validity of a single-item measure of general mental distress with established, multi-item mental health measures used in population-level surveillance and to establish the optimal cutpoint for determining psychological distress (previously identified as frequent mental distress) using recently available data from the Behavioral Risk Factor Surveillance System survey.

METHODS

Data for this study were obtained from the core questionnaire and two optional modules available as part of the 2006 and 2007 Behavioral Risk Factor Surveillance System (BRFSS) surveys. Frequent mental distress (FMD) was identified by the number of days of self-reported poor mental health during the last 30 days. Comparisons of the number of days with poor mental health and positive scores for measures of depression and serious mental illness were calculated to identify the most efficient cutpoint for establishing FMD.

RESULTS

Comparisons of results obtained from ROC analyses using the PHQ-8 and K6 reported 0.867 (95% CI 0.861-0.872) and 0.840 (95% CI 0.836-0.845) of the area under the curve, respectively, suggesting good accuracy. Using the Youden index, 6 days of poor mental health in the past 30 days, rather than the existing 14-day standard, was identified as the point at which the sum of the sensitivity and specificity was greatest.

CONCLUSION

Results from this study suggest that a 6-day standard (FMD-6) can be used as a valid and reliable indicator of generalized mental distress with strong associations to both diagnosable depressive symptomology and serious mental illness.

Prevalence of psychiatric and physical morbidity in an urban geriatric population

BACKGROUND

With a rapidly increasing population of older aged people, epidemiological data regarding the prevalence of mental and physical illnesses are urgently required for proper health planning. However, there is a scarcity of such data from India.

AIMS

To study the frequency and pattern of psychiatric morbidity present and the association of physical illness with psychiatric morbidity in an elderly urban population.

SETTINGS AND DESIGN

Cross-sectional, epidemiological study.

MATERIALS AND METHODS

All the consenting elderly persons in a municipal ward division (n=202) were enrolled after surveying a total adult population of 7239 people. A door to door survey was undertaken where the participants were interviewed and physically examined. General Health Questionnaire-12, Mini Mental State Examination, CAGE Questionnaire and Geriatric Depression Scale were used in the interview apart from consulting the available documents. Other family members were also interviewed to verify the information.

STATISTICAL ANALYSIS

Chi-square test with Yates correction.

RESULTS

Psychiatric illnesses were detected in 26.7% while physical illnesses were present in 69.8% of the population surveyed. Predominant psychiatric diagnoses were depressive disorders, dementia, generalized anxiety disorder, alcohol dependence and bipolar disorder. The most common physical illness was visual impairment, followed by cardiovascular disease, rheumatic illnesses, pulmonary illnesses, hearing impairment, genitourinary diseases and neurological disorders. Presence of dementia was associated with increased age, single/widowed/separated status, nuclear family, economic dependence, low education, cardiovascular disorders, rheumatic disorders and neurological disorders. Depression was associated with female sex, single/widowed/separated status, staying in nuclear families, economic dependence on others and co-morbid physical illnesses, specifically cardiovascular disorders and visual impairment.

CONCLUSIONS

This study presented a higher rate of dementia and old age depression. The interesting association with several sociodemographic factors as well as physical illnesses may have important implications for health planning.

Physical activity and depressive symptoms in community-dwelling elders from southern Brazil

OBJECTIVE: To determine the existence of a relationship between physical activity and depressive symptoms in community-dwelling elders. METHOD: This is a cross-sectional, population-based study, which included 379 community-dwelling elders from Novo Hamburgo, state of RS, Brazil. The level of physical activity was estimated using the International Physical Activity Questionnaire and depressive symptoms were diagnosed according to the Yesavage Geriatric Depression Scale. The association between the level of physical activity and depressive symptoms was analyzed by logistic regression. RESULTS: A tendency towards a lower prevalence of depressive symptoms was observed in individuals with higher levels of physical activity, both in the sample as a whole as well as among men, but not among women (p for linear trend 0.04, 0.03 and 0.36, respectively). The odds ratio of the presence of depressive symptoms in the very active group, as compared against that of the insufficiently active group was 0.32 (95% CI: 0.12-0.86) for men and 0.76 (95% CI: 0.39-1.46) for women. CONCLUSION: In this population of aged individuals, more intense physical activity is related to a lower prevalence of depressive symptoms. As shown by gender stratification, physical activity is inversely related to depressive symptoms in men, albeit not in women.

One-month prevalence of mental disorders in a population sample of 95-year olds

OBJECTIVE

To determine the 1-month prevalence of mental disorders among 95-year olds.

DESIGN

Cross-sectional population sample of 95-year olds.

SETTING

: All 95-year olds born in the period 1901-1903 living in Gothenburg, Sweden, were invited. Elderly living in both community settings and nursing homes were included.

PARTICIPANTS

In total, 338 95-year olds (response rate: 65%) were examined (263 women, 75 men).

MEASUREMENTS

All participants were examined by psychiatrists using the Comprehensive Psychopathological Rating Scale and cognitive tests. Mental disorders were classified according to Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised criteria.

RESULTS

Two-third of all 95-year olds had a mental disorder. In the total sample of 95-year olds, the 1-month prevalence was 52% for dementia, 8% for depression, 4% for anxiety, and 3% for psychotic disorders. Almost one-third (29%) of the nondemented 95-year olds fulfilled criteria for a psychiatric disorder: 17% had depression, 9% anxiety, and 7% psychotic disorder.

CONCLUSIONS

The combined prevalence of mental disorders was high among 95-year olds, even after excluding dementia. These findings emphasize the importance of research, care, and detection of psychiatric problems in this age group.

Association between median family income and self-reported mood symptoms in bipolar disorder

OBJECTIVE

There is broad consensus from epidemiologic research that lower socioeconomic status is related to poorer health. This study investigated the relation between median family income and self-reported mood symptoms in patients with bipolar disorder who reside in the United States.

METHODS

Two hundred eighty-four patients with bipolar disorder provided daily self-reported mood ratings for 6 months (50,054 days of data). Regardless of income, all patients were treated by a psychiatrist, took psychotropic medications, and participated in computerized self-monitoring throughout the study. Median family income was obtained from US census tract data. The association between income and mood was analyzed using income as both a continuous and categorical variable. Demographic characteristics were compared by income group. Education level was included in the analysis a priori.

RESULTS

Both the continuous and categorical approaches found a positive association between income and euthymia, a negative association between income and manic/hypomanic symptoms including those due to mixed states, and no association between income and depressive symptoms. Patients in the lower-income group spent 12.4% fewer days euthymic than those in the upper-income group and 9.7% fewer days euthymic than those in the middle-income group. Patients in the lower-income group spent 7.1% more days with manic/hypomanic symptoms than those in the upper-income group. There was no association between education and income.

CONCLUSION

Median family income is associated with mood symptoms in patients with bipolar disorder. Inclusion of income as a measure of socioeconomic status is recommended for future studies of outcome in bipolar disorder.

Long-acting injectable risperidone in partially adherent and nonadherent patients with schizophrenia

BACKGROUND

Long-acting injectable antipsychotics may improve medication adherence, thereby improving overall treatment effectiveness. This study aimed to evaluate the effectiveness, safety, and tolerability of risperidone long-acting injection in schizophrenic patients switched from oral antipsychotic medication.

METHODS

In a 12-month, multicenter, open-label, noncomparative study, symptomatically stable patients on oral antipsychotic medication with poor treatment adherence during the previous 12 months received intramuscular injections of risperidone long-acting injection (25 mg starting dose) every 2 weeks. The primary endpoint was the change in Positive and Negative Syndrome Scale (PANSS) total score.

RESULTS

Of the 60 patients who were screened, 53 received at least one injection (safety population), and 51 provided at least one postbaseline assessment. Mean PANSS total scores improved significantly throughout the study and at endpoint. Significant improvements were also observed in Clinical Global Impression of Severity, Personal and Social Performance, and Drug Attitude Inventory scales. Risperidone long-acting injection was safe and well-tolerated. Severity of movement disorders on the Extrapyramidal Symptom Rating Scale was reduced significantly. The most frequently reported adverse events were insomnia (22.6%), increased prolactin (17.0%), and weight gain (13.2%).

CONCLUSION

Risperidone long-acting injection was associated with significant symptomatic improvements in stable patients with schizophrenia following a switch from previous antipsychotic medications.

Subjective distress predicts treatment seeking for depression, bipolar, anxiety, panic, neurasthenia and insomnia severity spectra

OBJECTIVE

To examine correlates of mental health treatment seeking such as gender, diagnosis, impairment, distress and mastery.

METHOD

Longitudinal epidemiological data from the Zurich Study of common psychiatric syndromes, including unipolar and bipolar depression, panic, anxiety, neurasthenia and insomnia, were utilized. In longitudinal Generalized Estimating Equations, treatment seeking was regressed on measures of subjective distress and impairment, childhood family problems, mastery and number of comorbid diagnoses.

RESULTS

Approximately half of all treated participants across all six syndromes suffered from subthreshold disorders. Meeting full or subthreshold diagnostic criteria was associated with treatment seeking for insomnia. Being female was associated with treatment seeking for depression. The only variable highly and consistently associated with treatment seeking, across all syndromes, was subjective distress. Treated participants reported high levels of distress, work and social impairment in both diagnostic and subthreshold groups.

CONCLUSION

Subjective distress may be a better indicator of treatment seeking than symptom count.

Prevalence of psychiatric disorders among older adults in long-term care homes: a systematic review

BACKGROUND

The population of older adults in long-term care (LTC) is expected to increase considerably in the near future. An understanding of the prevalence of psychiatric disorders in LTC will help in planning mental health services for this population. This study reviews the prevalence of common psychiatric disorders in LTC populations.

METHODS

We searched electronic databases for studies on the prevalence of major psychiatric disorders in LTC using medical subject headings and key words. We only included studies using validated measures for diagnosing psychiatric disorders or psychiatric symptoms. Our review focused on the following psychiatric disorders: dementia, behavioral and psychological symptoms of dementia (BPSD), major depression, depressive symptoms, bipolar disorder, anxiety disorders, schizophrenia, and alcohol use disorders. We also determined the prevalence of psychiatric disorders in the U.S. LTC population using data from the 2004 National Nursing Home Survey (NNHS).

RESULTS

A total of 74 studies examining the prevalence of psychiatric disorders and psychological symptoms in LTC populations were identified including 30 studies on the prevalence of dementia, 9 studies on behavioral symptoms in dementia, and 26 studies on depression. Most studies involved few LTC facilities and were conducted in developed countries. Dementia had a median prevalence (58%) in studies while the prevalence of BPSD was 78% among individuals with dementia. The median prevalence of major depressive disorder was 10% while the median prevalence of depressive symptoms was 29% among LTC residents. There were few studies on other psychiatric disorders. Results from the 2004 NNHS were consistent with those in the published literature.

CONCLUSIONS

Dementia, depression and anxiety disorders are the most common psychiatric disorders among older adults in LTC. Many psychiatric disorders appear to be more prevalent in LTC settings when compared to those observed in community-dwelling older adults. Policy-makers and clinicians should be aware of the common psychiatric disorders in LTC and further research into effective prevention and treatments are required for this growing population.

Functional neuroimaging studies of bipolar disorder: examining the wide clinical spectrum in the search for disease endophenotypes

Bipolar disorder (BP) is among the top ten most disabling illnesses worldwide. This review includes findings from recent studies employing functional neuroimaging to examine functional abnormalities in neural systems underlying core domains of the psychopathology in BP: emotion processing, emotion regulation and executive control, and common comorbid features of BP, that are relevant to the wide spectrum of BP rather than focused on the more traditional BPI subtype, and that may facilitate future identification of diagnostically-relevant biomarkers of the disorder. In addition, an emerging number of studies are reviewed that demonstrate the use of neuroimaging to elucidate biomarkers whose identification may help to (1) identify at-risk individuals who will subsequently develop the illness to facilitate early intervention, (2) identify targets for treatment and markers of treatment response. The use of newer neuroimaging techniques and potential confounds of psychotropic medication upon neuroimaging findings in BP are also examined. These approaches will help to improve diagnosis and the mental well-being of all individuals with BP.

Smoking outcome by psychiatric history after behavioral and varenicline treatment

Treatment outcomes were compared across smokers enrolled in the COMPASS cessation trial with (positive psychiatric history [PH+], n = 271) and without (PH-, n = 271) a diagnosis of PH based on medical record evidence of anxiety, depression, psychotic disorder, or bipolar disorder. Everyone received behavioral counseling plus varenicline and was followed for 6 months post quit date. PH+ smokers took varenicline for fewer days on average (59.4 vs. 68.5, p < or = .01) but did not differ in their use of behavioral treatment. PH+ smokers were more likely to report anxiety and depression, but side-effect intensity ratings did not differ after adjusting for multiple comparisons. Overall, all side effects were rated as moderate intensity or less. Groups had similar 30-day abstinence rates at 6 months (31.5% PH+ vs. 35.4% PH-, p = .35). In sum, having a psychiatric diagnosis in this trial did not predict worse treatment outcome or worse treatment side effects.

Psychosocial correlates of binge eating in Hispanic, African American, and Caucasian women presenting for bariatric surgery

Research suggests that that binge eating, stress, and depression are prevalent among individuals seeking bariatric surgery. However, ethnic differences in the prevalence of binge eating and binge eating disorder (BED) in this population remain unclear, as does the impact of depression and stress on any such relationship. Further, no studies to date have examined the prevalence of binge eating in Hispanic women presenting for bariatric surgery. This study sought to (a) compare the prevalence and severity of binge eating symptomatology and BED diagnosis in Hispanic, African American, and Caucasian women presenting for gastric bypass surgery, (b) examine the impact of depressive symptoms and stress on binge eating symptomatology, and (c) investigate whether ethnicity moderated any relationship between depression, stress, and binge eating. Results indicated that Hispanic women exhibited equal rates of binge eating symptomatology, BED, and depressive symptomatology as African American and Caucasian women. However, Caucasian women exhibited greater binge eating symptomatology than African American women, and African American women endorsed greater levels of stress than Caucasian women. Across all ethnic groups, depressive symptomatology, but not stress, significantly predicted binge eating severity. These findings suggest that Hispanic women presenting for bariatric surgery report binge eating rates equivalent to Caucasian and African American women, and that depressive symptoms are an important predictor of binge eating in female bariatric surgery candidates across ethnic groups.

'Bipolar disorder' in the elderly: what's in a name?

Bipolar disorder is a chronic disorder of mood which leads to episodes of either elevated mood or depression in a sizable number of adults in the community (1%). Though the prevalence rates in the elderly are lower in the community (up to 0.1%), there is significantly higher morbidity in protected environments like care homes and hospital settings where prevalence rates may be as high as 10%. Bipolar disorder in the elderly is probably heterogenous and its etiopathogenesis is complex. Bipolar disorder may be divided into two distinct subtypes, the late onset bipolar (LOB) and the early onset bipolar (EOB) groups. LOB patients tend to have a milder illness in terms of manic severity but they have higher medical and neurological burden. They also have lower familial burden of bipolar illness as compared to EOB patients. There is an increased risk of dementia and stroke in patients with late life bipolar disorder (and there may be a protective effect of lithium in preventing dementia). White matter changes, as seen by increased white matter hyperintensities on neuroimaging, are also increased, providing further evidence of cerebrovascular disease. Treatment of late life bipolar is currently based on guidelines drawn up for younger bipolar disorder patients. Good quality intervention studies are needed to estimate the possible protective effect of cognitive enhancers and/or vascular prevention strategies. This review suggests that late life bipolar disorder, particularly late onset bipolar disorder, is probably a distinct diagnostic entity compared to the younger bipolar patients as it has a different presentation, etiology and hence perhaps needs different treatment strategies.

The ageing gut: diminished symptom response to a standardized nutrient stimulus

BACKGROUND The prevalence of dyspepsia and the severity of reflux symptoms decreases with advancing age. We postulate that advancing age influences sensory function and this will be associated with a diminished symptom response to a standardized meal stimulus.Our aim was to assess the influence of age on visceral sensory function. METHODS Baseline gastrointestinal symptoms and anxiety and depression were assessed in 53 healthy volunteers using validated questionnaires. After an 8-h fast, subjects received 200 mL of a standardized enteral feeding solution every 5 min up to a cumulative volume of 800 mL. After each 200 mL drink, five key symptoms were assessed (fullness, abdominal pain, retrosternal/abdominal burning, nausea and regurgitation) using a standardized instrument on visual analogue scales (0-100). The cumulative symptom score across all symptoms was calculated. KEY RESULTS Fullness was the most prominent symptom reported (79.8 +/- 9.5) followed by nausea (14.9 +/- 4.9) and pain (9.8 +/- 4.5); these three items accounted for more than 90% of the overall symptom load. The cumulative pain and nausea scores during a standardized nutrient challenge were significantly and inversely correlated with age (r = -0.43, P = 0.002 and r = -0.28, P = 0.045). Subjects >60 years of age reported significantly lower pain and nausea scores (0.9 +/- 0.9, 4.5 +/- 3.9) than did subjects <40 years (22 +/- 11.9, P = 0.002; 29.3 +/- 12, P = 0.043). CONCLUSIONS & INFERENCES Symptom responses to a standardized nutrient challenge, in particular pain and nausea, are inversely correlated with age.

The impact of institutional discrimination on psychiatric disorders in lesbian, gay, and bisexual populations: a prospective study

OBJECTIVES

We examined the relation between living in states that instituted bans on same-sex marriage during the 2004 and 2005 elections and the prevalence of psychiatric morbidity among lesbian, gay, and bisexual (LGB) populations.

METHODS

We used data from wave 1 (2001-2002) and wave 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (N = 34,653), a longitudinal, nationally representative study of noninstitutionalized US adults.

RESULTS

Psychiatric disorders defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, increased significantly between waves 1 and 2 among LGB respondents living in states that banned gay marriage for the following outcomes: any mood disorder (36.6% increase), generalized anxiety disorder (248.2% increase), any alcohol use disorder (41.9% increase), and psychiatric comorbidity (36.3% increase). These psychiatric disorders did not increase significantly among LGB respondents living in states without constitutional amendments. Additionally, we found no evidence for increases of the same magnitude among heterosexuals living in states with constitutional amendments.

CONCLUSIONS

Living in states with discriminatory policies may have pernicious consequences for the mental health of LGB populations. These findings lend scientific support to recent efforts to overturn these policies.

Toxoplasma and schizophrenia

Research on infectious agents as a possible cause of schizophrenia has become prominent in the past decade. Toxoplasma gondii has emerged as a prime candidate for a variety of reasons; (i) many studies have reported that individuals with schizophrenia, compared to controls, have a higher prevalence of antibodies to T. gondii, (ii) some individuals with adult toxoplasmosis develop psychotic symptoms similar to those of schizophrenia, (iii) epidemiologically, there are many similarities between toxoplasmosis and schizophrenia, (iv) antipsychotic drugs known to be effective in schizophrenia also inhibit some parasites, including T. gondii, (v) Toxoplasma has been shown to induce elevated levels of dopamine in experimentally infected animals (elevated dopamine is commonly seen in individuals with schizophrenia) and (vi) studies have shown that individuals with schizophrenia, compared to controls, have had greater exposure to cats in childhood. A number of questions remain concerning a role for Toxoplasma in the aetiology of schizophrenia, including the roles of strain variation, the timing and source of infection, and the role of host genes in determining disease susceptibility. The establishment of a firm association between Toxoplasma and the aetiology of schizophrenia and related disorders would represent a major breakthrough in the understanding of these disorders and would lead to novel methods for their treatment and prevention.

Heterogeneity of the jealousy phenomenon in the general population: an Italian study

INTRODUCTION

Despite the general agreement that normal jealousy is heterogenous, little is known about this specific topic.

METHODS

In the present study, we explored the possibility of distinguishing between four subtypes of "normal" jealousy (depressive, anxious, obsessive, and paranoid) amongst a cohort of 500 healthy university students by means of a specifically designed questionnaire, "Ouestionario della gelosia" (QUEGE). QUEGE is a self-report instrument of 30 items which explores the presence, frequency, and duration of feelings and behaviors related to jealousy. It was devised to investigate four hypothetical psychopathological profiles: depressive, paranoid, obsessive, and anxious.

RESULTS

The factor analysis identified five rather than four clear-cut factors: self-esteem, paranoia, interpersonal Sensitivity, fear of being abandoned, and obsessionality. Women showed statistically significant lower levels of self-esteem and higher levels of obsessionality than men. Younger age (<25 years) was associated with lower self-esteem and higher levels of paranoia and obsessionality, while being single was associated with lower self-esteem and higher levels of obsessionality.

CONCLUSION

The present study provides evidence of the reliability and validity of the QUEGE instrument, which seems to identify the presence of five psychopathological dimensions within the jealousy phenomenon in the general population.

The associations between socio-economic status and major depressive disorder among Blacks, Latinos, Asians and non-Hispanic Whites: findings from the Collaborative Psychiatric Epidemiology Studies

BACKGROUND

This study examined whether there were associations between individual measures of socio-economic status (SES) and the 12-month prevalence of major depressive disorder (MDD) in representative samples of Blacks, Latinos, Asians and Whites in the USA.

METHOD

The data used were from the Collaborative Psychiatric Epidemiology Studies (CPES).

RESULTS

There was an association between household income and MDD among Whites. However, the association was not statistically significant. Statistically significant associations were present between educational attainment and MDD among Whites. Among both Whites and Latinos, being out of the labor force was significantly associated with MDD. In analyses by nativity, being out of the labor force was significantly associated with MDD among US-born and foreign-born Latinos.

CONCLUSIONS

Significant associations between various measures of SES and MDD were consistently observed among White and, in some cases, Latino populations. Future studies should continue to examine sociopsychological factors related to SES that increase the risk of MDD among people from racial-ethnic communities.

Earlier stress exposure and subsequent major depression in aging women

OBJECTIVE

Despite evidence that stress exposure earlier in the life course may have long-term consequences for psychopathology, most models of vulnerability for late life depression are limited to current stressors or to retrospective reports of stress history. This study estimates the influences of earlier stressors assessed longitudinally on subsequent major depressive disorder (MDD) in women at average age 60 (range 50-75).

METHOD

MDD, negative life events (NLE), and marital stress were assessed multiple times in a community-based sample of 565 women followed for three decades. Adverse events experienced in childhood also were assessed prior to outcome.

RESULTS

Greater childhood adversity, earlier high levels of NLE and marital stress, and a more rapid increase in marital stress over time elevated the odds of MDD at average age 60 independent of all stressors and other salient risk factors. Childhood adversity was mediated in part by intervening risks. Prior depression, earlier poor health status, a more rapid deterioration in health with age, and current disability owing to physical problems also were related independently to later MDD.

CONCLUSIONS

These findings support the enduring effects of earlier stress burden on MDD in women into old age and, in light of the increasing proportion of older women in the population, have important clinical implications for identification and treatment of those at risk for depression. Findings also underscore the need to develop resources to counteract or buffer similar stress exposure in younger generations of women.
