Julia Z Zheng, Yangyi Li, Tuo Lin, Angelica Estrada, Xiang Lu, Changyong Feng
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...

In clinical research, comparisons of the results from experimental and control groups are often encountered. The two-sample t-test (also called independent samples t-test) and the paired t-test are probably the most widely used tests in statistics for the comparison of mean values between two samples. However, confusion exists with regard to the use of the two test methods, resulting in their inappropriate use. In this paper, we discuss the differences and similarities between these two t-tests. Three examples are used to illustrate the calculation procedures of the two-sample t-test and paired t-test...

Compulsive water drinking or psychogenic polydipsia is now increasingly seen in psychiatric populations. Effects of increased water intake can lead to hyponatremia causing symptoms of nausea, vomiting, seizures, delirium and can even be life threatening if not recognized and managed early. Here we present a 35-year old adult who was diagnosed with psychogenic polydipsia and was successfully managed with a combination of pharmacotherapy, fluid restriction and psychosocial management.

Hyponatremia is a rare, yet potentially life threatening complication of antipsychotics. Here, we report a case of a 45-year-old female diagnosed with schizophrenia who developed hyponatremia soon after addition of olanzapine to the existing treatment. This prompted us to evaluate the relationship between hyponatremia and olanzapine, as timely management is crucial. Naranjo algorithm established a "probable" causal relation between olanzapine and hyponatremia. Possible etiological reasons of this clinically significant and life threatening adverse event have been discussed...

Hashimoto's thyroiditis is a rare condition associated mainly with neurological symptoms. It contains an abundant amount of auto-antibodies in the blood. Only a few cases of behavioral symptoms without significant neurological disturbances have been recorded in the literature. In this view, our case is unique as it was not associated with overt hypothyroid manifestations.

The etiology of Major Depressive Disorder (MDD) is still unclear. We reviewed the literature for the relationship between inflammatory signaling and cytokines in the pathogenesis of MDD. In addition, we provid evidence for adjunctive treatment using anti-inflammatory drugs to improve the therapeutic effect and prognosis. Finally, we explore the possible relationship between the pathogenesis of MDD and immune disturbances.

BACKGROUND: Pregnancy is a period of transition, which makes women more vulnerable and in unfavorable conditions may lead to psychopathology in both mother and infant. It is essential to outline factors adversely affecting the resolution of this period. Early interventions and why they matter: Interventions during pregnancy can provide important improvement in the outcome for both maternal and infant mental health. AIM: The aim of the study is to evaluate the risk factors of antenatal anxiety and depression focusing particularly on maternal representations of the relationship towards the fetus and her own parents during pregnancy and the early postpartum period...

BACKGROUND: Schizophrenia is characterized by abnormal perception, thinking, emotions, and behaviors. Cognitive dysfunction is acknowledged as one of the most pivotal symptoms in schizophrenia. In addition to positive or negative symptoms, which had been proposed by Gallhofer in the early 1970s, schizophrenia patients suffered from cognitive impairments as well. Many studies show that there is genetic susceptibility in the first grading kinship of patients with schizophrenia. Patients with schizophrenia have cognitive impairment not only in the acute phase but also in the stable phase...
