Glucose, relational memory, and the hippocampus
Conclusions The discussion considers the cognitive processes and hippocampal basis for paired associate learning and retention and the implications for glucose’s mode of action. It is proposed that glucose during encoding serves to make the delayed memories initially more available, whereas its influence during delayed retrieval makes available memories temporarily more accessible.

Changes in serotonin transporter (5-HTT) gene expression in peripheral blood cells after MDMA intake
Conclusions Preliminary results show that MDMA causes substantial regulatory changes in the expression of serotonergic markers, likely being modulated by the 5-HTTLPR polymorphism. Changes in 5-HTT gene expression may play an important role in the regulation of mood state. (Source: Psychopharmacology)

Shifting from policy relevance to policy translation: do housing and neighborhoods affect children’s mental health?
This article offers guidance on interpreting evidence from observational studies for translation into policy, related to three policy-relevant elements of housing: receipt of affordable housing subsidies, the target population to which results generalize, and operationalization and modeling of neighborhood context. Policy translation is imperative for understanding which levers outside the health sector can be manipulated to change fundamental causes of mental health related to housing and neighborhood. Shifting from policy relevance to policy translation may be challenging, especially for understanding social causation in...

Inappropriate treatments for patients with cognitive decline
Conclusions Polypharmacy should be avoided, if it is not essential, especially in elderly patients and those with cognitive impairment. Benzodiazepines, opioids and anticholinergics often elicit cognitive and behavioural disorders. Moreover, systolic blood pressure must be kept above 130mmHg, total cholesterol levels over 160mg/dL, and HDL-cholesterol over 40mg/dL in this population. (Source: Neurologia)

Bioinformatic analyses and conceptual synthesis of evidence linking ZNF804A to risk for schizophrenia and bipolar disorder
Advances in molecular genetics, fueled by the results of large‐scale genome‐wide association studies, meta‐analyses, and mega‐analyses, have provided the means of identifying genetic risk factors for human disease, thereby enriching our understanding of the functionality of the genome in the post‐genomic era. In the past half‐decade, research on neuropsychiatric disorders has reached an important milestone: the identification of susceptibility genes reliably associated with complex psychiatric disorders at genome‐wide levels of significance. This age of discovery provides the groundwork for follow‐up studie...

Propranolol, post-traumatic stress disorder, and intensive care: incorporating new advances in psychiatry into the ICU
Post-traumatic stress disorder (PTSD) is a common complication of an ICU admission. Rarely is there a continuation of care, which is aimed at screening for and treating this debilitating disease. Current treatment options for PTSD are held back by inconsistent efficacy, poor evidence, and a lack of understanding of its psychopathology. Without ‘gold standard’ assessment techniques to diagnose PTSD after an ICU admission, the development of care pathways is hindered. This paper advocates for two interwoven advances in psychiatric care (specifically for PTSD) after ICU: (1) incorporate the monitoring and treating of psyc...

The longitudinal course of sleep timing and circadian preferences in adults with bipolar disorder
ConclusionsDisturbances of sleep timing are prominent in individuals with BP. These disturbances are worse during mood episodes, but still apparent during euthymic periods. Evening preference was not associated with polarity type, or mood state in BP, suggesting that this characteristic may be a trait marker. (Source: Bipolar Disorders)

Factor structure of the Spanish version of the Patient Health Questionnaire‐9 in Mexican women
We report the factor structure of the PHQ‐9 in 55,555 women from the Mexican Teachers' Cohort (MTC). Factor structure of the PHQ‐9 was assessed by exploratory and confirmatory factor analyses in two sub‐samples (n = 27,778 and 27,777 respectively). A one‐factor model of the PHQ‐9 was the solution with the best fit to the data, exhibiting strong factor loadings (0.71 to 0.90) and high internal consistency (Cronbach's alpha = 0.89). A prevalence rate of moderate to high severity of depressive symptoms of 12.6% was identified. Results suggest that a global score is an appropriate measure of depressive sympto...

The Relationship Between Stress and Social Functioning in Adults With Autism Spectrum Disorder and Without Intellectual Disability
Adults with autism spectrum disorder (ASD) face substantial challenges accomplishing basic tasks associated with daily living, which are exacerbated by their broad and pervasive difficulties with social interactions. These challenges put people with ASD at increased risk for psychophysiological distress, which likely factors heavily into social functioning for adults with ASD, as suggested by a growing literature on stress in children that indicates that children with ASD have differential responses to stress than healthy children. We hypothesized that adults with ASD and without intellectual disability (n = 38) would ...

Familial 1q22 microduplication associated with psychiatric disorders, intellectual disability and late-onset autoimmune inflammatory response
Conclusions: The rearrangement segregates with the neurological clinical features observed in our patients, suggesting that dosage imbalance of one or more genes in this genomic region may lead to the observed phenotype. The association between the microduplication and the inflammatory disease is much less evident. Additional reported patients carrying similar microduplications are needed to clarify this aspect.

Forced entrainment by using light therapy, modafinil and melatonin in a sighted patient with non-24-hour sleep-wake disorder
A 20-year-old female presented with sleep disturbances and daytime fatigue. She had been suffering from an irregular sleep-wake rhythm for 14 years. Her irregular sleep onset and wake-up times led to difficulty in falling asleep and waking up at the socially desired times. However, once asleep, she slept well for approximately 7 to 8 h. She had no medical illness or obvious head trauma, and no family history of such symptoms. Her neurological examination was unremarkable and vision was normal. Psychiatric disorders were screened with the Minnesota Multiphasic Personality Inventory (MMPI); there was no evidence of psychiatr...

Emotion recognition in unaffected first-degree relatives of individuals with first-episode schizophrenia
Impairments in recognising negative emotions are found in individuals with first-episode and chronic schizophrenia and also in those at ultra-high risk for the illness. Whether these impairments are an endophenotype for schizophrenia is unclear. To examine the heritability of emotion recognition, the aim of this study was to examine whether facial and prosody emotion recognition deficits, particularly for negative emotions, are also present in unaffected first-degree relatives of people with schizophrenia.

Insight in inpatients with schizophrenia: Relationship to symptoms and neuropsychological functioning
Lack of insight into illness has long been recognized as a central characteristic of schizophrenia. Although recent theories have emphasized neurocognitive dysfunction as a central impairment in schizophrenia it remains unclear whether the lack of insight in schizophrenia is more strongly associated with measures of symptom severity or neuropsychological dysfunction.

What is more familiar than I? Self, other and familiarity in schizophrenia
Familiarity disorders (FDs) critically impact social cognition in persons with schizophrenia. FDs can affect both relationships with people familiar to the patient and the patient's relationship with himself, in the case of a self-disorder. Skin conductance response (SCR) studies have shown that familiar and unknown faces elicit the same emotional response in persons with schizophrenia with FD. Moreover, in control subjects, one's own face and familiar faces have been shown to activate strongly overlapping neural networks, suggesting common processing. (Source: Schizophrenia Research)

No Evidence for Development of Tolerance after Repeated Use of Propofol for Electroconvulsive Therapy
Conclusions: In our study patients did not appear to develop tolerance to propofol after repeated administration. Although the lack of a systematic dosing scheme in our study limits the conclusions that can be drawn, recent studies in animal models indicate that tolerance development is rather unlikely with propofol. Further studies are required to clarify the question of whether repeated use of propofol leads to tolerance.[...]© Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents  |  Abstract  |  Full text (Source: Pharmacopsychiatry)

Changes in Brain-derived neurotrophic factor (BDNF) during abstinence could be associated with relapse in cocaine-dependent patients
Brain-derived neurotrophic factor (BDNF) is involved in cocaine craving in humans and drug seeking in rodents. Based on this, the aim of this study was to explore the possible role of serum BDNF in cocaine relapse in abstinent addicts. Forty cocaine dependent subjects (DSM-IV criteria) were included in an inpatient two-weeks abstinence program. Organic and psychiatric co-morbidities were excluded. Two serum samples were collected for each subject at baseline and at after 14 abstinence days. After discharge, all cocaine addicts underwent a 22 weeks follow-up, after which they were classified into early relapsers (ER) (resum...

Relationship between the Rorschach perceptual thinking index (PTI) and the positive and negative syndrome scale (PANSS) in psychotic patients: A validity study
The aim of this study is to demonstrate the validity of the Rorschach Perceptual Thinking Index (PTI) in the assessment of reality testing in patients with psychosis. We evaluated the relationship between the PTI criteria and the Positive and Negative Syndrome Scale (PANSS) scores in 98 psychotic disorder affected patients. 34 were evaluated during the acute episode (AP) and 64 were chronically treated and stable (CP). The PANSS positive score resulted significantly higher in AP than in CP group, but no significant difference was found in the PTI score. (Source: Psychiatry Research)

Temperament and character as predictors of recurrence in remitted patients with major depression: a four-year prospective follow-up study
The aim of the present study was to examine whether the specific personality traits, Harm-Avoidance (HA) and Self-Directedness (SD) as measured by the Temperament and Character Inventory (TCI), was predictive for subsequent depressive episodes in remitted patients with major depressive disorders (MDD) over a four-year follow-up. A total of 109 inpatients with MDD participated in this study. The subjects completed the TCI when they were assessed to be in remission. They were divided into high or low HA groups and high or low SD groups, as discriminated by the quartile value. (Source: Psychiatry Research)

Effects of remission speed and improvement of cognitive functions of depressed patients
Major depressive disorder (MDD) presents neuropsychological alterations which improve after the treatment, but it might be mediated by clinical variables. Our goal is to study whether the speed of remission of MDD bears any relation to the improvement of the patients’ cognitive functioning after a successful treatment. We carried out clinical and neuropsychological assessments of 51 patients with MDD. After these procedures they underwent a 24-week treatment with fluoxetine, and were assessed again with the same battery used prior to treatment. (Source: Psychiatry Research)
