Enhancement in cognitive function recovery by granulocyte-colony stimulating factor in a rodent model of traumatic brain injury

Tue, 09/16/2014 - 2:18pm

Traumatic brain injury (TBI) is characterized by neuronal damage and commonly, secondary cell death, leading to functional and neurological dysfunction. Despite the recent focus of TBI research on developing therapies, affective therapeutic strategies targeting neuronal death associated with TBI remain underexplored. This study explored the efficacy of granulocyte-colony stimulating factor (G-CSF) as an intervention for improving cognitive deficits commonly associated with TBI. Although G-CSF has been studied with histological techniques, to date, its effects on functional outcome remain unknown. To this end, we used a closed head injury (CHI) model in Wistar rats that were randomly assigned to one of four groups (untreated TBI, G-CSF treated TBI, G-CSF treated Control, Control). The treatment groups were administered subcutaneous injections of G-CSF 30 min (120 mug/kg) and 12 h (60 mug/kg) post-trauma. The Morris Water Maze test was used to measure any treatment-associated changes in cognitive deficits observed in TBI animals at days 2-6 post-injury. Our findings demonstrate a significant improvement in cognitive performance in the G-CSF treated TBI animals within a week of injury, compared to untreated TBI, indicative of immediate and beneficial effect of G-CSF on cognitive performance post CHI. Our model suggests that early G-CSF exposure may be a promising therapeutic approach in recovery of cognitive deficits due to TBI.

A DSM-5 to-do list for adult psychiatry residency directors

Tue, 09/16/2014 - 2:18pm

A small study within the author's department, comparing resident and faculty attitudes toward the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5), revealed that the DSM-5 transition process is starting from a point in which neither faculty nor residents are optimistic that the new DSM will result in improved diagnosis or treatment. However, the publication of DSM-5 presents training directors with opportunities to engage trainees in the study of the evolution of psychiatric nosology and the evidence for core psychiatric diagnoses. Residents should be encouraged to become familiar with both DSM-5 and National Institute of Mental Health Research Domain Criteria (NIMH RDoC) categories in their study of the neurobiology of psychiatric disorders. Department chairs are encouraged to establish timelines for the DSM-5 transition for faculty, residents, medical student teaching, medical record keeping, and billing for services. Training directors should be aware that national examinations for trainees will transition gradually between 2014 and 2017, so comparisons should be made whenever possible between DSM-IV-TR and DSM-5. To minimize trainee confusion, departments should attend to the coherence of transition timelines among faculty, resident, and medical student training.

Implementing an intervention for parents with mental illness: Building workforce capacity

Tue, 09/16/2014 - 2:18pm

OBJECTIVE: This article describes the challenges in building workforce capacity when implementing an intervention for families living with parental mental illnesses. METHOD: Data were obtained in the context of a larger, developmental, mixed-methods study. Participants included all agency employees working with families in the Family Options intervention on a daily basis. In-depth interviews were representative of the implementation time frame and activities, and the range of staff members' roles and involvement in the implementation process. Themes emerged as interview transcripts were coded qualitatively using a constant comparative approach. RESULTS: Identifying complex family needs, anticipating the needs of children, and addressing staff needs for training and support were crucial considerations in implementing a family intervention. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: As the psychiatric rehabilitation field acknowledges the impact of family life on adults as well as children, and moves toward family informed services, knowledge of how to shape and support this specialized workforce is essential.

The role of coping in depression treatment utilization for VA primary care patients

Tue, 09/16/2014 - 2:18pm

OBJECTIVE: To examine the impact of Veterans' coping strategies on mental health treatment engagement following a positive screen for depression. METHODS: A mixed-methods observational study using a mailed survey and semi-structured interviews. Sample included 271 Veterans who screened positive for depression during a primary care visit at one of three VA medical centers and had not received a diagnosis of depression or prescribed antidepressants 12 months prior to screening. A subsample of 23 Veterans was interviewed. RESULTS: Logistic regression models showed that Veterans who reported more instrumental support and active coping were more likely to receive depression or other mental health treatment within three months of their positive depression screen. Those who reported emotional support or self-distraction as coping strategies were less likely to receive any treatment in the same time frame. Qualitative analyses revealed that how Veterans use these and other coping strategies can impact treatment engagement in a variety of ways. CONCLUSIONS: The relationship between Veterans' use of coping strategies and treatment engagement for depression may not be readily apparent without in-depth exploration. PRACTICE IMPLICATIONS: In VA primary care clinics, nurse care managers and behavioral health providers should explore how Veterans' methods of coping may impact treatment engagement.

Risk factors for suicide among 34,671 patients with psychotic and non-psychotic severe depression

Tue, 09/16/2014 - 2:18pm

BACKGROUND: Severe unipolar depression is associated with increased risk of suicide, but it remains unknown whether the same risk factors are present in the non-psychotic (non-PD) and psychotic (PD) subtypes respectively. Therefore, this study aimed to identify risk factors for suicide in non-PD and PD separately, and to investigate if the presence of psychotic symptoms is an independent risk factor for suicide in severe depression. METHODS: This register-based, nationwide, historical prospective cohort study used logistic regression analyses to ascertain risk factors for suicide among all adults diagnosed with severe depression at Danish psychiatric hospitals between January 1, 1994 and December 31, 2010. The risk for suicide was expressed as adjusted odds ratios (AOR). RESULTS: A total of 34,671 individuals with severe depression (non-PD: n=26,106 and PD: n=12,101) were included in the study. Of these, 755 completed suicide during follow up. PD was not found to be an independent risk factor for suicide in severe depression (AOR=0.97 [0.83-1.15]). Older age (non-PD AOR=1.05 [per year], PD AOR=1.04 [per year]), male sex (non-PD AOR=1.89, PD AOR=1.98), and a previous incident of self-harm (non-PD AOR=5.02, PD AOR=5.17) were significant risk factors for both groups. LIMITATIONS: As the study population was comprised only of patients with contact to psychiatric hospitals, the results cannot be extrapolated to the primary care setting. CONCLUSION: The following risk factors for non-PD and PD were identified: older age, male gender and previous incidents of self-harm. In suicide prevention efforts, equal attention should be paid to non-PD and PD patients.

Vagus Nerve Stimulation and Food Intake: Effect of Body Mass Index

Tue, 09/16/2014 - 2:18pm

Animal research suggests that vagus nerve stimulation (VNS) is associated with weight loss and decreased appetite. Results from human studies are mixed; some suggest that VNS affects weight whereas others do not, and it is unclear how VNS affects eating behaviors. Baseline body mass index (BMI) and VNS device settings may moderate the effects of VNS on caloric intake. This study investigates the association among BMI, VNS device settings, and caloric intake of highly palatable foods during VNS on versus VNS off sessions in 16 adult patients (62.5% female; BMI mean = 29.11 +/- 6.65) using VNS therapy for either epilepsy or depression. Participants attended 2 experimental sessions (VNS on versus off) where they were presented with 4 preferred snack foods totaling 1600 calories. At the start of the session, they either had their VNS devices turned off or left on. Caloric intake was calculated by weighing foods before and after each session. BMI category (overweight/obese and lean) was the between group factor in the analysis. After controlling for covariates, an interaction of condition and BMI category (P = .03) was found. There was an interaction of condition and device output current (P = .05) and a trend toward an interaction of condition and device on time (P = .07). Excess weight may impact how neurobiological signals from the vagus nerve affect appetite and eating. Future research is needed to further elucidate this relationship.

Appealing Features of Vocational Support Services for Hispanic and non-Hispanic Transition Age Youth and Young Adults with Serious Mental Health Conditions

Tue, 09/16/2014 - 2:18pm

Transition age youth and young adults (TAYYAs) diagnosed with serious mental health conditions (SMHCs) are at greater risk of being unemployed compared to their peers without SMHCs. Job counseling and job placement services are the greatest predictor of competitive employment, yet we have limited knowledge about what TAYYAs believe they need to obtain gainful employment. In person, qualitative interviews were conducted with 57 non-Hispanic and Hispanic TAYYAs with SMHCs enrolled in three vocational support programs in MA (Vocational Rehabilitation, Individual Placement and Support; the Clubhouse Model as described by the International Center for Clubhouse Development). Six themes emerged from the data: three themes were identified as social capital (supportive relationships, readily available workplace supports, and vocational preparation), two themes related to human capital (effective educational supports and work experience), and one theme related to cultural capital (social skills training). Unique features (Spanish-speaking staff and/or familiar in Latino culture, familial-like staff support) were frequently noted by Hispanic TAYYAs.

What Happens to Mental Health Treatment During Pregnancy? Women's Experience with Prescribing Providers

Tue, 09/16/2014 - 2:18pm

This exploratory study completed interviews with 25 depressed pregnant women who had prior depression, and when becoming pregnant, were receiving depression medication or tried to get mental health care. Seventy one percent of women were more than 25 weeks gestation at the time of the interview. Thirty-five percent of women were not receiving treatment. While 94 % told their provider of their pregnancy, 36 % had no opportunity to discuss the risks and benefits of continued pharmacotherapy; 42 % had no opportunity to continue pharmacotherapy. Some providers may be reluctant to treat depressed pregnant women, creating a potential barrier to their receipt of needed care.

Medicaid lapses and low-income young adults' receipt of outpatient mental health care after an inpatient stay

Tue, 09/16/2014 - 2:18pm

OBJECTIVE: This study examined low-income young adults' use of outpatient mental health services after an inpatient mental health stay, with a focus on Medicaid enrollment lapses and public mental health safety-net coverage. METHODS: The sample included 1,174 young adults ages 18 to 26 who had been discharged from inpatient psychiatric care in a mid-Atlantic state. All were enrolled in Medicaid at the time of discharge, and all were eligible for continued outpatient public mental health services regardless of Medicaid enrollment. Administrative claims data were used to examine outpatient mental health clinic use, psychotropic medication possession, inpatient readmission, and emergency department admission during the 365-day period after the index discharge. The main independent variable was a lapse in Medicaid enrollment. An instrumental-variables regression model was used to minimize estimation bias resulting from unmeasured confounding between lapses and service use. RESULTS: Nearly a third (30%) of the young adults had an enrollment lapse. In instrumental-variables analysis, those whose coverage lapsed were less likely than those who had continuous Medicaid coverage to have at least two clinic visits (38% versus 80%); they also had a lower average psychotropic medication possession ratio (25% versus 55%). CONCLUSIONS: Age-related Medicaid enrollment lapses were common in this sample of young adults and were associated with receipt of less clinical care postdischarge despite continued eligibility for public services. States should examine opportunities to assist young adults with serious mental health problems who are aging out of Medicaid enrollment categories for children.

Identifying young adults at risk of Medicaid enrollment lapses after inpatient mental health treatment

Tue, 09/16/2014 - 2:18pm

OBJECTIVE: This study sought to describe Medicaid disenrollment rates and risk factors among young adults after discharge from inpatient psychiatric treatment. METHODS: The sample included 1,176 Medicaid-enrolled young adults ages 18 to 26 discharged from inpatient psychiatric care in a mid-Atlantic state. Medicaid disenrollment in the 365 days postdischarge and disenrollment predictors from the 180-day predischarge period (antecedent period) were identified from administrative records. Classification and regression tree and probit regression analysis were used. RESULTS: Thirty-two percent were disenrolled from Medicaid within a year of discharge. Both analytical approaches converged on four main risk factors: being in the Medicaid enrollment category for persons with a nondisabled low-income parent or for a child in a low-income household, being age 18 or 20 at discharge, having a Medicaid enrollment gap in the antecedent period, and having no primary care utilization in the antecedent period. For the 48% of the sample continuously enrolled in the antecedent period who were in the enrollment categories for disabled adults or foster care children, the disenrollment rate was 13%. CONCLUSIONS: A substantial minority of Medicaid-enrolled young adults discharged from inpatient care were disenrolled from Medicaid within a year. About half the sample had a low disenrollment risk, but the other half was at substantial risk. Risk factors largely reflected legal status changes that occur among these transition-age youths. Identifying inpatients at high risk of disenrollment and ensuring continuous coverage should improve access to needed postdischarge supports. Regular primary care visits may also help reduce unintended Medicaid disenrollment in this population.

Posttraumatic stress disorder and substance use disorder comorbidity among individuals with physical disabilities: findings from the National Comorbidity Survey Replication

Tue, 09/16/2014 - 2:18pm

Co-occurring posttraumatic stress disorder (PTSD) and substance use disorder (SUD) affects multiple domains of functioning and presents complex challenges to recovery. Using data from the National Comorbidity Study Replication, a national epidemiological study of mental disorders (weighted N = 4,883), the current study sought to determine the prevalence of PTSD and SUD, the symptom presentation of these disorders, and help-seeking behaviors in relation to PTSD and SUD among individuals with physical disabilities (weighted n = 491; nondisabled weighted n = 4,392). Results indicated that individuals with physical disabilities exhibited higher rates of PTSD, SUD, and comorbid PTSD/SUD than nondisabled individuals. For example, they were 2.6 times more likely to meet criteria for lifetime PTSD, 1.5 times more likely for lifetime SUD, and 3.6 times more likely for lifetime PTSD/SUD compared to their nondisabled peers. Additionally, individuals with physical disabilities endorsed more recent/severe PTSD symptoms and more lifetime trauma events than nondisabled individuals with an average of 5 different trauma events compared to 3 in the nondisabled group. No significant pattern of differences was noted for SUD symptom presentation, or for receipt of lifetime or past-year PTSD or SUD treatment. Implications of these findings and recommendations for future research are discussed.

Eye-tracking measures reveal how changes in the design of aided AAC displays influence the efficiency of locating symbols by school-age children without disabilities

Tue, 09/16/2014 - 2:18pm

PURPOSE Many individuals with communication impairments use aided augmentative and alternative communication (AAC) systems involving letters, words, or line drawings that rely on the visual modality. It seems reasonable to suggest that display design should incorporate information about how users attend to and process visual information. The organization of AAC symbols can influence the speed and accuracy with which children select a target symbol on a display. This research examined why some displays facilitate responding. METHOD Eye-tracking technology recorded point-of-gaze while children without disabilities engaged in a visual search task with 2 AAC displays. In 1 display, symbols sharing an internal color were clustered together. In the other display, like-colored symbols were distributed. Dependent measures were (a) latency to fixate on the target compared with distracters and (b) the number of fixations to target and distracters. RESULTS Participants were significantly slower to fixate on the target when like-colored symbols were distributed; there was a significant increase in the number of fixations to distracters that did not share color with the target. CONCLUSIONS Efficient search was related to minimizing fixations to nonrelevant distracters. Vulnerability to distraction can be a significant problem in individuals with disabilities who use AAC. Minimizing the intrusion of such distraction may, therefore, be of importance in AAC display design.

Recent research related to juvenile sex offending: findings and directions for further research

Tue, 09/16/2014 - 2:18pm

Serious scholarly inquiry into juvenile sex offending represents a relatively new field, dating from the mid 1940s. During the next 4 decades, a mere handful of articles exploring aspects of juvenile sex offending were added to the available literature. By the 1980s, however, the literature began to increase rapidly, a trend that continues today. The purpose of this article is a focused review of the juvenile sex offender literature cited in PubMed over the last 5 years (2009-2013). The authors have chosen studies that will bring readers up to date on research they believe impacts our current understanding of best practices in the management of juvenile sex offending. For convenience, our review is organized into topical categories including research into characteristics and typologies of juvenile sex offenders, risk assessment and recidivism, assessment and treatment, the ongoing debate about mandatory registration of sex offenders as it applies to juveniles, and other thought provoking studies that do not fit neatly into the aforementioned categories. The studies included contain findings that both reinforce and challenge currently held notions about best practices concerning treatment and public policy, suggesting that our knowledge of the field continues to evolve in important ways.

Effect of sertraline on risk of falling in older adults with psychotic depression on olanzapine: results of a randomized placebo-controlled trial

Tue, 09/16/2014 - 2:18pm

OBJECTIVE: Observational studies report that selective serotonin reuptake inhibitor (SSRI) antidepressants are associated with an increased risk of falls in the elderly, but these studies may overestimate drug-specific risk because of confounding. A randomized controlled trial (RCT) is the optimal way to assess the causal relationship between use of an SSRI and falls. We therefore analyzed data from a RCT of the treatment of psychotic depression, to examine whether combined olanzapine and sertraline interacted with older age to increase the risk of falling compared with olanzapine plus placebo. DESIGN: Double-blind placebo-controlled RCT. SETTING: Four academic medical centers. PARTICIPANTS: Two hundred fifty-nine patients with major depressive disorder with psychotic features (N = 117 aged 18-59 years and N = 142 aged 60 years or older). INTERVENTION: Twelve weeks of randomized double-blind treatment with olanzapine plus sertraline or olanzapine plus placebo. MEASUREMENTS: Proportion of participants who fell at least once. RESULTS: Older participants were significantly more likely than younger participants to fall. Among older participants, the odds ratio of falling with olanzapine plus sertraline versus olanzapine plus placebo was 1.56 (95% confidence interval: 0.63-3.83). There was not a statistically significant treatment effect or treatment x age interaction with respect to the proportion of participants falling. These negative results may have been due to low statistical power. CONCLUSION: Evaluating the association between SSRIs and falls in a RCT is limited by the large sample size that is required. An alternative approach is to examine the effect of an SSRI on measures of postural stability and gait that are valid markers of risk of falling. Elsevier Inc. All rights reserved.

Neuropsychiatry and neuroscience education of psychiatry trainees: attitudes and barriers

Tue, 09/16/2014 - 2:18pm

OBJECTIVE: The American Association of Directors of Psychiatric Residency Training (AADPRT) Task Force on Neuropsychiatry and Neuroscience Education of Psychiatry Residents was established in 2011 with the charge to seek information about what the field of psychiatry considers the core topics in neuropsychiatry and neuroscience to which psychiatry residents should be exposed; whether there are any "competencies" in this area on which the field agrees; whether psychiatry departments have the internal capacity to teach these topics if they are desirable; and what the reception would be for "portable curricula" in neuroscience. METHODS: The task force reviewed the literature and developed a survey instrument to be administered nationwide to all psychiatry residency program directors. The AADPRT Executive Committee assisted with the survey review, and their feedback was incorporated into the final instrument. RESULTS: In 2011-2012, 226 adult and child and adolescent psychiatry residency program directors responded to the survey, representing over half of all US adult and child psychiatry training directors. About three quarters indicated that faculty resources were available in their departments but 39% felt the lack of neuropsychiatry faculty and 36% felt the absence of neuroscience faculty to be significant barriers. Respectively, 64 and 60% felt that neuropsychiatry and psychiatric neuroscience knowledge were very important or critically important to the provision of excellent care. Ninety-two percent were interested in access to portable neuroscience curricula. CONCLUSIONS: There is widespread agreement among training directors on the importance of neuropsychiatry and neuroscience knowledge to general psychiatrists but barriers to training exist, including some programs that lack faculty resources and a dearth of portable curricula in these areas.

Peripartum depression and anxiety as an integrative cross domain target for psychiatric preventative measures

Tue, 09/16/2014 - 2:18pm

Exposure to high levels of early life stress has been identified as a potent risk factor for neurodevelopmental delays in infants, behavioral problems and autism in children, but also for several psychiatric illnesses in adulthood, such as depression, anxiety, autism, and posttraumatic stress disorder. Despite having robust adverse effects on both mother and infant, the pathophysiology of peripartum depression and anxiety are poorly understood. The objective of this review is to highlight the advantages of using an integrated approach addressing several behavioral domains in both animal and clinical studies of peripartum depression and anxiety. It is postulated that a greater focus on integrated cross domain studies will lead to advances in treatments and preventative measures for several disorders associated with peripartum depression and anxiety.

A scoping review of interprofessional collaborative practice and education using the lens of the Triple Aim

Tue, 09/16/2014 - 2:18pm

The Triple Aim unequivocally connects interprofessional healthcare teams to the provision of better healthcare services that would eventually lead to improved health outcomes. This review of the interprofessional education (IPE) and collaborative practice empirical literature from 2008 to 2013 focused on the impact of this area of inquiry on the outcomes identified in the Triple Aim. The preferred reporting items for systematic reviews and meta-analyses methodology were employed including: a clearly formulated question, clear inclusion criteria to identify relevant studies based on the question, an appraisal of the studies or a subset of the studies, a summary of the evidence using an explicit methodology and an interpretation of the findings of the review. The initial search yielded 1176 published manuscripts that were reduced to 496 when the inclusion criteria were applied to refine the selection of published manuscripts. Despite a four-decade history of inquiry into IPE and/or collaborative practice, scholars have not yet demonstrated the impact of IPE and/or collaborative practice on simultaneously improving population health, reducing healthcare costs or improving the quality of delivered care and patients' experiences of care received. We propose moving this area of inquiry beyond theoretical assumptions to systematic research that will strengthen the evidence base for the effectiveness of IPE and collaborative practice within the context of the evolving imperative of the Triple Aim.

Effects of perinatal depression and anxiety on labor and delivery outcomes

Tue, 09/16/2014 - 2:18pm

INTRODUCTION: The purpose of this study was to determine how perinatal depression and anxiety effect obstetric outcomes and perceptions of labor and delivery experiences. METHODS: This prospective observational study examined the labor and delivery experiences of 25 high-risk and 25 low-risk women. The high-risk group was defined by symptoms during pregnancy as determined by the Edinburgh Postnatal Depression Scale, whereas the low-risk group reported no symptoms. Women in both groups were monitored with the Hamilton Rating Scales for depression and anxiety and filled out a questionnaire about their labor and delivery. RESULTS: The high-risk cohort had significantly more depressive symptoms than the low-risk cohort throughout pregnancy and into the postpartum period (P<.001). Similarly, the high-risk cohort had significantly more anxiety symptoms than the low-risk cohort (P<.001). The high-risk cohort was significantly more likely to report their labor and delivery was a traumatic experience (P=.046) and to have their labor induced (P=.018) as compared with the low-risk cohort. There was no significant difference in the rates of preterm labor (P=.149) or method of delivery (P=1.00) between both groups. CONCLUSIONS: Factors such as preterm labor, labor induction, and cesarean deliveries can cause women to report having traumatic deliveries. It is not known whether labor induction alone caused traumatic birth experiences or whether mood was a predisposing factor to a traumatic delivery. More research must be done to identify the mechanisms by which mood can influence labor and delivery outcomes.
