Abstract
BACKGROUND Patients with bipolar disorder (BD) and patients with major depressive disorder (MDD) have relatively specific temperament and structural abnormalities of brain regions related to emotion and cognition. However, the effects of temperament factors on the structure of frontal and temporal cortex is still unclear. The aims of this study were to explore the differences and relationships between temperament characteristics and the gray matter volume of frontal and temporal cortex in patients with BD or MDD. METHODS T1-weighted magnetic resonance imaging (MRI) data, demographic and clinical information were obtained from 279 depressed patients (90 patients with BD, 189 patients with MDD) and 162 healthy controls (HC). Temperament was assessed with the Chinese short version of Temperament Evaluation of Memphis, Pisa and San Diego - Auto questionnaire (TEMPS-A). The Desikan-Killiany atlas was used for yielding gray matter volume by FreeSurfer 6.0 software suite. A total of 22 frontal and temporal regions were chosen as regions of interest (ROIs). RESULTS Compared with patients with MDD, patients with BD had higher TEMPS-A total scores and scores on cyclothymic, irritable and hyperthymic subscales. The gray matter volume in bilateral rostral middle frontal gyrus (RMFG), left temporal pole and right superior frontal gyrus were reduced in patients with BD. Patients with MDD only had lower gray matter volume in bilateral temporal pole. In the pooled patients, there were negative associations between hyperthymia and gray matter volume in right RMFG. CONCLUSION Patients with BD and MDD had different temperament characteristics. The prominent temperament subscales in patients with BD were cyclothymia, irritable and hyperthymia. Patients with greater hyperthymia had lower gray matter volume in right frontal gyrus. Temperament may reflect an endophenotype in patients with mood disorders, especially in BD.

Abstract
PURPOSE OF REVIEW To give an update on recent imaging studies probing positron emission tomography (PET) as a tool for improving biomarker-guided diagnosis of neuropsychiatric disorders. RECENT FINDINGS Several studies confirmed the value of imaging of regional neuronal activity and imaging of dopaminergic, serotonergic, and other neuroreceptor function in the diagnostic process of neuropsychiatric disorders, particularly schizophrenia, depression/bipolar disorder, substance use disorders, obsessive compulsive disorders (OCD), and attention-deficit/hyperactivity disorder. Additionally, imaging brain microglial activation using translocator protein 18 kDa (TSPO) radiotracer allows for unique in-vivo insights into pathophysiological neuroinflammatory changes underlying schizophrenia, affective disorders, and OCD. SUMMARY The role of PET imaging in the biomarker-guided diagnostic process of neuropsychiatric disorders has been increasingly acknowledged in recent years. Future prospective studies are needed to define the value of PET imaging for diagnosis, treatment decisions, and prognosis in neuropsychiatric disorders.

Abstract
INTRODUCTION Although numerous risk factors have been described, the effects of temperament, which is defined as a risk factor for certain disorders, on the outcome of patients undergoing rotator cuff surgery have not been investigated. HYPOTHESIS We investigated whether a relationship exists between affective temperament and the outcome of patients undergoing rotator cuff surgery. MATERIAL AND METHODS The outcomes of 176 patients undergoing rotator cuff surgery were examined using the Oxford and Constant questionnaires as well as visual analog scale values preoperatively and postoperatively. Inclusion criteria were defined as 1) dissatisfaction with pain despite 6 months of nonoperative treatment; 2) rotator cuff defects with full-thickness, small- to large-sized defects; 3) presence of a single dominant temperament or nondominant temperament; 4) no history of a diagnosed psychiatric disorder; and 5) a minimum of greater than 1 year of follow-up after surgery. Exclusion criteria were 1) other comorbid shoulder pathology; 2) irreparable or partial rotator cuff rupture; 3) grade 3 retractions; 4) grade 3-4 fatty infiltration; 5) other comorbid diseases such as diabetes, thyroid disorders, or inflammatory diseases; 6) history of shoulder surgery; 7) infection of the shoulder joint; 8) neurologic deficit in muscles around the shoulder; 9) two or more dominant temperaments; and 10) history of acromioclavicular joint resection and/or biceps tenodesis with cuff repair. All patient temperaments were evaluated according to the Temperament Evaluation of Memphis, Pisa, Paris and San Diego auto questionnaire version. RESULTS The mean follow-up time was 45.5 months. The outcomes of patients with depressive temperament were worse than of patients with a nondominant temperament. This situation was observed both preoperatively and postoperatively. However, a similar relationship between nondominant and anxious temperament groups was observed only postoperatively. CONCLUSION We noticed that depressive and anxious temperaments had a negative effect on patient outcomes after rotator cuff surgery; however, nondominant temperaments had a positive effect on patient outcomes. LEVEL OF EVIDENCE Level III; Retrospective Comparative Study.

Abstract
INTRODUCTION Subthreshold presentations of bipolarity (BSPs) pose a diagnostic conundrum, in terms of whether they should be conceptualized and treated similarly as traditionally defined bipolar disorders (BD). While it has been argued that BSPs are on a pathophysiologic continuum with traditionally defined BDs, there has been limited examination of biological and objective markers in these presentations to validate this assertion. Areas covered: The authors review studies examining genetic, neurobiological, cognitive and peripheral markers in BSPs, encompassing clinical and non-clinical populations with subthreshold hypo/manic symptoms. Results are placed in the context of previously identified markers in traditionally defined BDs. Expert commentary: There have been few studies of objective and biological markers in subthreshold presentations of BD, and results are mixed. While abnormalities in brain structure/functioning, peripheral inflammatory, and cognitive markers have been reported, it is unclear whether these findings are specific to BD or indicative of broad affective pathology. However, some studies suggest that increased sensitivity to reward and positive stimuli are shared between subthreshold and traditionally defined BDs, and may represent a point of departure from unipolar major depression. Further examination of such markers may improve understanding of subthreshold bipolar presentations, and provide guidance in terms of therapeutic strategies.
