Specialized inpatient treatment for young people with early psychosis: acute-treatment and 12-month results.

The objective of the study was to investigate the development of clinical outcomes of young people with early psychosis in a specialized inpatient treatment and assess the feasibility of such an intervention in an inpatient setting. The study was a prospective cohort study of patients with early psychosis treated at the specialized inpatient treatment "Fühinterventions-und Therapiezentrum, FRITZ" (early intervention and therapy center) in Berlin, Germany. The primary outcomes were attitudes towards psychiatric medication and patient satisfaction with treatment after 6 weeks.

Clinical Risk Constellations for the Development of Bipolar Disorders.

The early recognition of psychiatric disorders has been a focus of research in the last decades and has led to improvements in clinical care, especially in the area of early psychosis. Like non-affective psychosis, bipolar disorders are often diagnosed with a delay that can lead to long periods of untreated illness and impact long-term outcomes. This article presents the rationale for early recognition in bipolar disorder and presents the current evidence for the identification of risk factors, their assessment and validity in predicting the onset of bipolar disorder.

The relationship between cannabis use and cognition in people diagnosed with first-episode psychosis.

Cannabis use is highly prevalent among young people diagnosed with first-episode psychosis (FEP), however, its impact on cognition is still unclear. The aim of the present study was to examine the association of cannabis use with cognition in people diagnosed with FEP. We extended previous research findings by operationalising the comorbid cannabis use, considering recency of cannabis use and use of other illicit substances and including people with a broad spectrum of psychotic diagnoses.

Creativity in persons at-risk for bipolar disorder-A pilot study.

Aim: The association between bipolar disorder and creativity may be related to symptoms of the disorder itself or personality traits present before the onset. To further explore the relationship between creativity and clinical risk for bipolar disorder, creativity among individuals with a history of depressive disorder and varying risk for future (hypo-)manic episodes was assessed and compared.

Methods: Thirty-eight participants completed the diagnostic process, including Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) Diagnosis, Hamilton Depression Scale and Young Mania Rating Scale.

[Service Use of an Early Intervention Centre, Clinical and Sociodemographic Characteristics of Young Adults with Early Psychosis with and without Migration Background].

Background: The present study evaluated service use of our newly established Early Intervention and Treatment Centre (FRITZ) in Berlin for young adults with first or early psychosis with and without migration background.

Methods: We conducted a retrospective chart review of in-patients with early psychosis who were admitted to FRITZ between May 2014 and May 2015. We investigated the proportion of patients with migration background, sociodemographic and clinical characteristics of patients.

Effects of intravitreal insulin and insulin signaling cascade inhibitors on emmetropization in the chick.

Purpose: Intravitreal insulin has been shown to be a powerful stimulator of myopia in chickens, in particular if the retinal image is degraded or defocused. In most tissues, the insulin receptor activates two main signaling pathways: a) the mitogen-activated protein kinase (MAPK) cascade (e.g.

Ultrasonography and optical low-coherence interferometry compared in the chicken eye.

Purpose: To compare ocular biometry [anterior chamber depth (ACD), lens thickness (LT), vitreous chamber depth (VCD), and axial length (AL)] using A-scan ultrasonography and optical low-coherence interferometry (OLCI) in the chicken eye.

Methods: Two-week-old chicks (n = 42) were measured. Bland-Altman plots and repeatability and correlation analyses were calculated for both methods.

Relative axial myopia in Egr-1 (ZENK) knockout mice.

Purpose: Experiments in chickens have implicated the transcription factor ZENK (also known as Egr-1, NGFI-A, zif268, tis8, cef5, and Krox24) in the feedback mechanisms for visual control of axial eye growth and myopia development. ZENK is upregulated in retinal glucagon amacrine cells when axial eye growth is inhibited by positive spectacle lens wear and is downregulated when it is enhanced by negative spectacle lens wear, suggesting that ZENK may be linked to an inhibitory signal for axial eye growth. This study was undertaken to determine whether a Egr-1(-/-) knockout mouse mutant, lacking ZENK completely, has longer eyes and more myopic refraction, than do Egr-1(+/)(-) heterozygous and Egr-1(+/+) wild-type mice with near-identical genetic backgrounds.

Regulation of Egr-1, VIP, and Shh mRNA and Egr-1 protein in the mouse retina by light and image quality.

Purpose: To analyze mRNA expression changes of Egr-1, VIP, and Shh under different light and treatment conditions in mice. The mRNA expression levels of the three genes and additionally the Egr-1 protein expression were compared in form deprived eyes and eyes with normal vision. Moreover, the influence of dark to light and light to dark transitions and of changes in retinal illumination on mRNA levels was investigated.

Pupillographic evaluation of the time course of atropine effects in the mouse eye.

Purpose: The nonselective muscarinic antagonist atropine is currently the most potent drug against myopia development in both humans and animal models. However, the mechanism by which myopia is suppressed is still unknown, and the time course of its action is not well documented. Therefore, we have studied the duration of mydriasis in the mouse, a new model of myopia, after topical application of a single eye drop with different doses of atropine.

Localization and regulation of glucagon receptors in the chick eye and preproglucagon and glucagon receptor expression in the mouse eye.

Myopia is a condition in which the eye is too long for the focal length of cornea and lens. Analysis of the messengers that are released by the retina to control axial eye growth in the animal model of the chicken revealed that glucagon-immunoreactive amacrine cells are involved in the retinal image processing that controls the growth of the sclera. It was found that the amount of retinal glucagon mRNA increased during treatment with positive lenses and pharmacological studies supported the idea that glucagon may act as a stop signal for eye growth.

Measurement of refractive state and deprivation myopia in two strains of mice.

Purpose: The mouse eye has a bright retinal image (f/number <1) but low optical quality (visual acuity about 0.5 cpd) that may render emmetropization unnecessary. However, this species is potentially a powerful model to study eye growth and myopia because its genome can be readily manipulated and has been completely sequenced.
