Review Meta AnalysisBrain gray matter alterations and associated demographic profiles in adults with autism spectrum disorder: A meta-analysis of voxel-based morphometry studies.
There is increasing evidence that children with autism spectrum disorder are accompanied by specific anatomical alterations. However, the anatomical abnormalities in adults with autism spectrum disorder are poorly understood. This study was aimed to identify the neuroanatomical substrates underlying the pathophysiology of adults with autism spectrum disorder. We also investigated the relationship between neuroanatomical alterations and clinical and demographic characteristics. ⋯ These findings confirmed that the neuroanatomical alterations in the fronto-temporal cortices, limbic system and cerebellum in adult individuals with autism were different from the children and young adolescent's autism. The effects of demographic characteristics on the brain morphological changes allow us to further clarify the neurobiological mechanisms and developmental trajectory in adult population with autism spectrum disorder.

Review Meta AnalysisMortality associated with anxiolytic and hypnotic drugs-A systematic review and meta-analysis.
Use of hypnotics or anxiolytic drugs is common and various studies have reported increased mortality with hypnotics or anxiolytic use. ⋯ This meta-analysis suggests that hypnotics or anxiolytics drugs use is associated with increased mortality and hence should be used with caution. Future studies focused on underlying mechanism of increased mortality with hypnotics or anxiolytics use are required.

Observational StudyPsychiatric comorbidities of adults with early- and late-onset attention-deficit/hyperactivity disorder.
We evaluated the psychiatric comorbidities in adults who were diagnosed with Diagnostic and Statistical Manual of Mental disorders, 5th edition attention-deficit/hyperactivity disorder as a function of recalled symptom onset before and after the age of 7 years and whether the childhood attention-deficit/hyperactivity disorder symptoms were associated with psychiatric comorbidities. ⋯ Our findings suggest that elevating the threshold of age of onset to 12 years in Diagnostic and Statistical Manual of Mental disorders, 5th edition would not over-diagnose attention-deficit/hyperactivity disorder in the adult population. Recalled childhood attention-deficit/hyperactivity disorder symptom severity was correlated with conduct disorder, oppositional defiant disorder, dysthymia and sleep disorders.

Menstrual cycle characteristics in women with persistent schizophrenia.
Oestradiol has been implicated in the pathogenesis of schizophrenia. Women with schizophrenia often suffer with menstrual dysfunction, usually associated with low oestradiol levels, but whether menstrual dysfunction has an effect on their psychiatric symptoms is not well researched. The aim of this study is to document the menstrual characteristics of women with chronic schizophrenia with focus upon menstrual regularity, menstrual cycle length and menstrual symptoms. To determine which patient characteristics are associated with irregular menses and whether irregular menses are associated with the severity of psychotic symptoms, menstrual symptoms or depressive symptoms. ⋯ Regular menses are associated with higher oestradiol levels and higher rates of cyclical mood symptoms but are not associated with Positive and Negative Syndrome Scale scores. Understanding the effect the menstrual cycle can have on psychiatric illness, such as premenstrual exacerbations, is important for the holistic care of women with schizophrenia.

Practice GuidelineRoyal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the management of schizophrenia and related disorders.
This guideline provides recommendations for the clinical management of schizophrenia and related disorders for health professionals working in Australia and New Zealand. It aims to encourage all clinicians to adopt best practice principles. The recommendations represent the consensus of a group of Australian and New Zealand experts in the management of schizophrenia and related disorders. This guideline includes the management of ultra-high risk syndromes, first-episode psychoses and prolonged psychoses, including psychoses associated with substance use. It takes a holistic approach, addressing all aspects of the care of people with schizophrenia and related disorders, not only correct diagnosis and symptom relief but also optimal recovery of social function. ⋯ This clinical practice guideline for the management of schizophrenia and related disorders aims to improve care for people with these disorders living in Australia and New Zealand. It advocates a respectful, collaborative approach; optimal evidence-based treatment; and consideration of the specific needs of those in adverse circumstances or facing additional challenges.
