Objective: To detect early subclinical signs of autonomic dysfunction in the cardiovascular system
and explore the mechanism of orthostatic hypotension (OH) in patients with multiple system atrophy
(MSA). Methods: Eighteen male patients with possible MSA and 10 healthy men were recruited.
The hemodynamic responses to head-up tilt and tilt-reversal were studied by an electrically-powered
tilt table and a non-invasive cardiac output measurement (NICOM) system. Results: At supine, there
was no signifi cant difference in blood pressure, heart rate (HR), stroke volume, cardiac output and
total peripheral resistance between MSA patients and healthy controls. During tilting upright, OH
developed in 5 MSA patients, with a 23.7±4.8 mmHg drop in systolic blood pressure. Patients with
OH were older and exhibited higher scores in unifi ed Multiple System Atrophy Rating Scale part I
than patients without OH. The stroke volume, cardiac output and total peripheral resistance did not
differ between groups. The controls had the most signifi cant HR elevation (6.5±2.5 bpm) during tiltup,
followed by patients without OH (2.8±1.6 bpm) and those with OH (-0.2±2.2 bpm). A similar
trend of HR decrease was observed during return to supine posture. The process of tilt-reversal altered
HR more signifi cantly than head-up tilt in controls (8.0±2.9 vs 6.5±2.5 bpm; P=0.031) and patients
without OH (4.2±2.1 vs 2.8±1.6 bpm; P=0.032), but not in patients with OH (1.2±1.5 vs -0.2±2.2
bpm; P=0.380).
Conclusions: The HR change during postural challenge showed signifi cant difference between MSA
patients and healthy controls. Impaired HR responsiveness contributed to OH in MSA. Monitoring HR
during the tilt table test may be a practical and useful method to detect early autonomic dysfunction
in patients with MSA.

Objectives:
:Based on the fact that cognitive functions decline known as comorbid symptoms of depression can precede depression, this study seeks to observe the effects of depressive symptoms and anxiety symptoms on cognitive function in healthy subjects.
Methods:
:To recruit 50 general populations to evaluate cognitive and clinical symptoms and to find out the effects of clinical symptoms on cognitive functions, Pearson correlation and multivariate regression were conducted. Correlation analysis of subdomain cognitive function was conducted for reliability analysis.
Results:
:Trail making test-B that evaluates the execution function correlates with depressive symptoms (r=0.300, p=0.03) and age (r=0.323, p=0.02). Depressive symptoms (β=0.304, p=0.03) and age (β=0.335, p=0.01) were significantly related to Trail making test -B (Adjusted R2 =0.148). Subjective cognitive tests correlates with anxiety symptoms (r=0.434, p=0.002). In the correlation between cognitive functional items, Subjective cognitive tests was found to be correlated with other test except Spotter.
Conclusions
:In this study, depressive symptoms contribute independently to executive functions in addition to demographic characteristics such as age and duration of education. Given that cognitive decline is a common long-term clinical outcome in depression, we expect active early intervention and evaluation of cognitive function to be helpful.

Background:
Circadian rhythms have gained importance in the field of psychiatry because of their involvement in overall body functions and their association with mental health. This study investigated the relationship between circadian rhythms, depressive symptoms, anxiety symptoms, and chronotype.
Methods:
Circadian rhythms, depression and anxiety symptoms, hypomanic symptoms, quality of life, hopelessness, and chronotype were evaluated in 30 healthy adults.
Results:
Multiple linear regression analysis revealed statistically significant correlations between Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) scores and certain factors. Particularly, Quick Inventory of Depressive Symptomatology (p=0.009), Beck Anxiety Inventory (p=0.03), and Morningness-Eveningness Questionnaire (p<0.001) were found to be significant predictors of the degree of circadian rhythm disruption, as measured by BRIAN. The results showed that irregularity in circadian rhythms was associated with depression and anxiety symptoms, and no significant correlation was observed between chronotype and irregularity in the circadian rhythms. The findings indicated that misalignment between an individual’s chronotype and societal norms, such as work schedules and meal times, could contribute to circadian rhythm disruption, particularly in individuals with an evening chronotype. In contrast, this disruption was associated with an increased risk of anxiety and depression.
Conclusion
These findings provide important information to better understand the impact of circadian rhythms on mental health.

OBJECTIVES: It has been reported that first episode polarity affected the course and the prognosis of bipolar disorder. However, there is remarkable paucity of information regarding first episode polarity in bipolar disorder. We investigated the clinical characteristics related to the first episode polarity of bipolar patients who had been hospitalized. METHODS: Analyses were based on the medical documents of 520 bipolar patients who had been hospitalized in 4 hospitals. We examined clinical features of the current episode, demographics, past treatment history, suicidal attempt history, family history and comorbidity. Clinical characteristics were compared between manic onset and depressive onset patients. RESULTS: The mean age of the patients was 36.7 years old; they had 2.1 number of admission history and 6.6 years of illness duration. The patients beginning with depressive onset was 39.4%, and they had more diagnosis of bipolar II disorder, more number of suicidal attempts and reported more depressive mood during index admission than manic onset patients. CONCLUSION: Depressive onset is a common presentation in bipolar disorder. It is necessary to give more attention to depressive episode in bipolar disorder. Prospective study needs to explore the correlation of first-episode of polarity and course of the illness in the future.

Endocrinology and Metabolism 2017;32(3):332-338
Discoveries of somatic mutations permit the recognition of subtypes of aldosterone-producing adenomas (APAs) with distinct clinical presentations and pathological features. Catenin β1 (CTNNB1) mutation in APAs has been recently described and discussed in the literature. However, significant knowledge gaps still remain regarding the prevalence, clinical characteristics, pathophysiology, and outcomes in APA patients harboring CTNNB1 mutations. Aberrant activation of the Wnt/β-catenin signaling pathway will further modulate tumorigenesis. We also discuss the recent knowledge of CTNNB1 mutation in adrenal adenomas.
