Genetic optimism:Framing genes and mental illness in the news

Over the past two decades the pace and specificity of discoveries associating genetics with mental illness has accelerated, which is reflected in an increase in news coverage about the genetics of mental disorder. The news media is a major source of public understanding of genetics and a strong influence on public discourse. This paper examines the news coverage of genetics and mental illness (i.e., bipolar illness and schizophrenia) over a 25 year period, emphasizing the peak period of 1987-1994. Using a sample of 110 news stories from 5 major American newspapers and 3 news magazines, we identify the frame of "genetic optimism" which dominated the reporting of genetics and mental illness beginning in the mid-1980s. The structure of the frame is comprised of 3 elements: a gene for the disorder exists; it will be found; and it will be good. New discoveries of genes were announced with great fanfare, but the most promising claims could not be replicated or were retracted in short order. Despite these disconfirmations, genetic optimism persisted in subsequent news stories. While the scientific accuracy of the gene stories is high, the genetic optimism frame distorts some of the findings, misrepresents and reifies the impact of genes on mental disorder, and leaves no space for critics or an examination of potential negative impacts. The stances of reporters, scientists and editors may all in different ways contribute to the perpetuation of genetic optimism. Genetic optimism presents an overly sanguine picture of the state of genetics; as we enter the genetic age it is important to balance the extraneous "hype and hope" contained in news stories of genetics and mental illness.

Mental health needs of children and youth with learning disabilities:Overview of a community needs assessment

The purpose of the present report is to describe a community needs assessment that puts the process and choice of a suitable approach into a context. The study examined the mental health needs of children and youth with learning disabilities and their families and how they fit within the continuum of services in Metropolitan Toronto. A series of recommendations was developed for the Ministry of Community and Social Services. The recommendations emphasize: prevention, training and consultation, and research. The study illustrates the importance of involving relevant constituencies in both the planning of a needs assessment and the formulation and implementation of recommendations based on the investigation.

Combating the mental health stigma with nostalgia

We report research implicating nostalgia as an intrapersonal means of warding off the stigmatization of persons with mental illness. We hypothesized and found that nostalgia about an encounter with a person with mental illness improves attitudes toward the mentally ill. In Experiment 1, undergraduates who recalled an encounter with a mentally ill person while focusing on central (vs. peripheral) features of the nostalgia prototype reported a more positive outgroup attitude. This beneficial effect of nostalgia was mediated by greater inclusion of the outgroup in the self (IOGS). In Experiment 2, undergraduates who recalled a nostalgic (vs. ordinary) interaction with a mentally ill person subsequently showed a more positive outgroup attitude. Results supported a serial mediation model whereby nostalgia increased social connectedness, which predicted greater IOGS and outgroup trust. IOGS and outgroup trust, in turn, predicted more positive outgroup attitudes. We ruled out alternative explanations for the results (i.e., mood, perceived positivity, and typicality of the recalled outgroup member). The findings speak to the intricate psychological processes underlying the prejudice-reduction function of nostalgia and their interventional potential. Copyright © 2013 John Wiley & Sons, Ltd.

The impact of hyperemesis gravidarum on maternal mental health and maternal-fetal attachment

In addition to physical health risks, it has been postulated that hyperemesis gravidarum (HG) - severe and persistent nausea and vomiting during pregnancy - can adversely affect maternal mental health and maternal-fetal attachment.

Quantitative estimation of retinal nerve fiber layer height in glaucoma and the relationship with optic nerve head topography and visual field

Purpose: The authors estimated the retinal nerve fiber layer height (RNFLH) measurements in patients with glaucoma compared with those in age-matched healthy subjects as obtained by the laser scanning tomography and assessed the relationship between RNFLH measurements and optic and visual field status. Methods: Parameters of optic nerve head topography and RNFLH were evaluated in 125 eyes of 21 healthy subjects and 104 patients with glaucoma using the Heidelberg Retina Tomograph ([HRT] Heidelberg Engineering GmbH, Heidelberg, Germany) for the entire disc area and for the superior 70°(50°temporal and 20°nasal to the vertical midline) and inferior 70°sectors of the optic disc. The mean deviation of the visual field, as determined by the Humphrey program 24-2 (Humphrey Instruments, Inc., San Leonardo, CA, U.S.A) was calculated in the entire field and in the superior and inferior Bjerrum area. Result: Retinal nerve fiber layer height parameters (mean RNFLH and RNFL cross-sectional area) were decreased significantly in patients with glaucoma compared with healthy individuals. Retinal nerve fiber layer height parameters was correlated strongly with rim volume, rim area, and cup/disc area ratio. Of the various topography measures, retinal nerve fiber layer (RNFL) parameters and cup/disc area ratio showed the strongest correlation with visual field mean deviation in patients with glaucoma. Conclusion: Retinal nerve fiber layer height measures were reduced substantially in patients with glaucoma compared with age-matched healthy subjects. Retinal nerve fiber layer height was correlated strongly with topographic optic disc parameters and visual field changes in patients with glaucoma.

Lower corneal hysteresis in glaucoma patients with acquired pit of the optic nerve (APON)

Objective: Acquired pit-like changes of the optic nerve head (APON) are characteristic of glaucomatous damage and may be a sign of a localized susceptibility of the optic nerve. Thus, it is possible that biomechanical properties of the ocular tissues may play a pressure-independent role in the pathogenesis of glaucoma. Corneal hysteresis (CH) appears to provide information of the biomechanical properties of the ocular hull tissues. The purpose of this study was to compare CH of patients with primary open angle glaucoma (POAG) with and without APON. Methods: A prospective case control study was done. POAG patients with and without APON were measured using the Ocular Response Analyzer by masked investigators. Patients in both groups were matched for sex, age, corneal thickness, and type of glaucoma according to maximal IOP (NTG or POAG). Statistical analysis was done using ANOVA. Results: Corneal hysteresis of 16 glaucomatous eyes with APON and 32 controls (glaucoma without APON) was measured. The mean (±SD) CH in the APON group was 8.89 (±1.53) and 10.2 (±1.05) in the control group. The difference is statistically significant (p = 0.005). Conclusions: Corneal hysteresis in POAG patients with APON was significantly lower than in patients that did not have such structural changes of the optic disc. These findings may reflect pressure-independent mechanisms involved in the pathogenesis of such glaucomatous optic nerve changes. © Springer-Verlag 2007.

The effects of the Omagh bomb on adolescent mental health: a school-based study

Background: The main objective of this study was to assess psychiatric morbidity among adolescentsfollowing the Omagh car bombing in Northern Ireland in 1998.

Methods: Data was collected within schools from adolescents aged between 14 and 18 years via a selfcompletionbooklet comprised of established predictors of PTSD; type of exposure, initialemotional response, long-term adverse physical problems, predictors derived from Ehlers andClark’s (2000) cognitive model, a PTSD symptoms measure (PDS) and the General HealthQuestionnaire (GHQ).

Results:Those with more direct physical exposure were significantly more likely to meet caseness onthe GHQ and the PDS. The combined pre and peri trauma risk factors highlighted in previousmeta-analyses accounted for 20% of the variance in PDS scores but the amount of varianceaccounted for increased to 56% when the variables highlighted in Ehlers and Clark’scognitive model for PTSD were added.

Conclusions: High rates of chronic PTSD were observed in adolescents exposed to the bombing. Whilstincreased exposure was associated with increased psychiatric morbidity, the best predictors ofPTSD were specific aspects of the trauma (‘seeing someone you think is dying’), what youare thinking during the event (‘think you are going to die’) and the cognitive mechanismsemployed after the trauma. As these variables are in principle amenable to treatment theresults have implications for teams planning treatment interventions after future traumas.

Effectiveness of Criminal Justice Liaison and Diversion Services for Offenders With Mental Disorders: A Review

Objective: The authors evaluated and synthesised the best-available evidence relating to the effectiveness of CJLD service models with respect to changes in mental health status and/or criminal recidivism.Methods: Research examining the effectiveness of CJLD services when compared to traditional Criminal Justice System (CJS) responses was reviewed and systematically appraised according to Campbell/Cochrane guidelines. Key outcomes included a reduction in offending and post-intervention changes in mental health. Results: Comprehensive searches of published and unpublished literature identified 6571 studies which varied considerably in terms of their methodological approach and overall quality. Ten studies met the inclusion criteria. The synthesised findings indicated that, when compared to traditional CJS outcomes, CJLD services appeared to be effective in terms of identifying MDOs and impacting positively on criminal justice and mental health outcomes.Conclusions: Although the evidence may be deemed to be moderate in terms of methodological rigour, overall, the findings suggest that CJLD services can be beneficial. The effectiveness of services depends upon the model of service delivery, the availability of community services and the engagement of MDOs.The successful implementation of CJLD services requires a clearer recognition of the importance of system of care principles.

Nerve pathology in the type 1 diabetic dog: effects of treatment with sulindac

The purpose of this study was to define pathological abnormalities in the peripheral nerve of a large animal model of long-duration type 1 diabetes and also to determine the effects of treatment with sulindac. Detailed morphometric studies were performed to define nerve fiber and endoneurial capillary pathology in 6 control dogs, 6 type 1 diabetic dogs treated with insulin, and 6 type 1 diabetic dogs treated with insulin and sulindac for 4 years. Myelinated fiber and regenerative cluster density showed a non-significant trend toward a reduction in diabetic compared to control animals, which was prevented by treatment with sulindac. Unmyelinated fiber density did not differ among groups. However, diabetic animals showed a non-significant trend toward an increase in axon diameter (p <0.07), with a shift of the size frequency distribution towards larger axons, which was not prevented by treatment with sulindac. Endoneurial capillary density and luminal area showed a non-significant trend toward an increase in diabetic animals, which was prevented with sulindac treatment. Endoneurial capillary basement membrane area was significantly increased (p <0.05) in diabetic animals, but was not prevented with sulindac treatment. We conclude that the type 1 diabetic dog demonstrates minor structural abnormalities in the nerve fibers and endoneurial capillaries of the sciatic nerve, and treatment with sulindac ameliorates some but not all of these abnormalities.
