Sample size is a critical parameter for clinical studies. However, to many biomedical and psychosocial investigators, power and sample size analysis seems like a magic trick of statisticians. In this paper, we continue to discuss power and sample size calculations by focusing on binary outcomes. We again emphasize the importance of close interactions between investigators and biostatisticians in setting up hypotheses and carrying out power analyses.

Cinema, a vehicle of social transformation sheds light on different aspects of mental illness. Due to its dramatic and stigmatising depictions, it often spreads a negative aspect of psychiatric disorders and the patients who are suffering from them. Though it brings out a few positive and inspiring stories, they are sparse in comparison to its negative views. Here, we are going to describe the dual impact of cinema on psychiatry.

Obsessive-compulsive disorder (OCD) is a chronic, distressing and substantially impairing neuropsychiatric disorder, characterized by obsessions or compulsions. The current case describes a 44-year-old adult female diagnosed with OCD. The patient had an incomplete response to several SSRIs alone during her past treatment, and led a poor-quality life for at least three years. Current multidimensional approaches, including combined cognitive behavioral therapy (CBT) and the Selective Serotonin Reuptake Inhibitor (SSRI, Sertraline) with a small dose of antipsychotics (Aripiprazole) for augmentation, as well as familial support and resources from the internet were provided for the patient for six months...

Background: Tardive dyskinesia (TD) is an abnormal involuntary movement disorder caused by patients' long-term use of antipsychotic medication. It diminishes the social functioning of patients with mental disorders, thereby affecting their compliance with antipsychotic medication. The cause and nosogenesis of TD remains unclear; furthermore, because the presentation differs greatly among individuals it often goes undiagnosed or can be easily misdiagnosed. The present study aims to evaluate the abnormal movement patterns in patients with TD, and analyze the differences among different TD patterns, in order to seek effective methods of preventing, diagnosing and treating TD...

Background: Schizophrenia is a chronic debilitating disease. The pathogenesis and treatment may be associated with inflammatory cytokines. There are few studies focusing on the prediction of cytokines in response to antipsychotics. Aim: To investigate whether cytokines would predict response to antipsychotics. Methods: Cross-sectional and natural observational cohort studies were applied to:(1) compare the baseline levels of serum IL-1β, TNF-α and MCP-1 between schizophrenia (n=64) and healthy controls (n=53); (2) To investigate the impact of baseline cytokines to psychopathology following olanzapine and risperidone monotherapy...

Background: The etiology and pathomechanism of schizophrenia are unknown. The traditional dopamine (DA) hypothesis is unable to fully explain its pathology and therapeutics. The glutamate (Glu) and γ-aminobutyric acid (GABA) hypotheses suggest Glu or GABA concentrations are abnormal in the brains of patients with schizophrenia. Magnetic resonance spectroscopy (MRS) show glutamate level increases in the ventromedial prefrontal cortex (vmPFC) including the anterior cingulated cortex (ACC) in those with schizophrenia...

Background: Impairments in emotional experience and expression have been observed in patients with schizophrenia. However, most previous studies have been limited to either emotional experience (especially anhedonia) or expression. Few studies have examined both the experience and expression of emotion in schizophrenia patients at the same time. Aims: The present study aimed to examine pleasure experience and emotion expression in patients with schizophrenia. In particular, we specifically examined the relationship between emotion impairments (both pleasure experience and expression) and negative symptoms...

REVIEW
Yanbing Xiong, Xianbin Ll, Lei Zhao, Chuanyue Wang
Background: Previous meta-analysis revealed that mismatch negativity(MMN) amplitude decreased in patients with schizophrenia compared with healthy controls (Cohen's d, d about 1), leading to the possibility of mismatch negativity being used as a biomarker for schizophrenia. However, it is unknown whether MMN is reliably changed in Chinese patients. It is necessary to carry out a meta-analysis on MMN of Han Chinese patients with schizophrenia. Aim: To investigate whether MMN could be used as a biomarker for Han Chinese patients with schizophrenia...

Sample size justification is required for all clinical studies. However, to many biomedical and clinical researchers, power and sample size analysis seems like a magic trick of statisticians. In this note, we discuss power and sample size calculations and show that biomedical and clinical investigators play a significant role in making such analyses possible and meaningful. Thus, power analysis is really an interactive process and scientific researchers and statisticians are equal partners in the research enterprise...

For a long time, eating disorders were considered as culture-bound syndromes, specific to Western countries. This theory has been refuted for anorexia, but few transcultural studies have been carried out on bulimia nervosa. As a result, knowledge concerning this disorder is limited. On the basis of a clinical case involving a bulimic Chinese girl, we attempt to demonstrate the impact of cultural factors on the disorder. We discuss the atypical characteristics of her symptom profile, in particular the absence of preoccupations concerning her appearance and the psycho-pathological impact of the secrecy surrounding her adoption...

Cholinesterase inhibitors and N-methyl-D-aspartic receptor antagonists are currently the main treatments for Alzheimer's disease (AD), targeting the clinical symptoms of AD. β-amyloid (Aβ) deposition and the highly-phosphorylated Tau protein-induced neurofibrillary tangles are some of the common pathological features of AD. In the past 20 years, many new drugs that focus on the pathogenesis of Alzheimer's disease have been assessed in clinical trials. Drugs such as β-amyloid monoclonal antibody and gamma-secretase inhibitor target the Aβ pathological pathway...

BACKGROUND: Presently, the internet plays a big role in daily life, especially for adolescents. In this age group, they are more concerned about their face and body shape. Despite the numerous studies on the effect traditional media has on body image, very few have focused on the effect of newer forms of media (e.g. online media). And almost none have looked at the relationship between time spent online and body image. AIM: To study the associations between time spent on the internet, body image satisfaction and eating behaviors of students grades 7 to 12 in the Thai educational system...

BACKGROUND: Eating disorder is culture related, and the clinical symptoms are different between eastern and western patients. So the validity of feeding and eating disorders in the upcoming ICD-11 guide for Chinese patients is unclear. AIMS: To explore the latent class structure of Chinese patients with eating disorder and the cross-cultural validity of the eating disorder section of the new ICD-11 guide in China. METHODS: A total of 379 patients with eating disorders at Shanghai Mental Health Center were evaluated using the EDI questionnaire and a questionnaire developed by researchers from 2010 to 2016...
