    Abstract Somatic Symptom Disorder is a specific disorder that is extensively defined by the Diagnostic and Statistical Manual of Mental Disorders, Fifth edition (DSM-5). Although the diagnostic criteria for somatic symptom disorder has archived breakaway from mind-body dualism and simplification for physicians, it remains vague and universally unapplicable. Moreover, despite the DSM-5 removing etiology in diagnosis, there is still a need to determine the etiology for individualized patient treatment. In particular, patients with somatic symptom disorder and relative disorders have psychological pathologies, such as somatization and anxiety about illness, all of which require psychiatric treatment. However, these patients initially visit physicians, not psychiatrists, since their symptoms are somatic, and they are anxious about the possibility of a physical disease. As such, supportive attitude and continuous treatment are important, as they can be performed even without a psychiatric consultation. Furthermore, while the effectiveness of pharmacotherapy is limited for these disorders, psychotherapy has the possibility to bring about a fundamental resolution. Particularly, cognitive behavior therapy or psychoanalytic psychotherapy has been found to be effective; however, they require high motivation and take up much time from the patients. Fortunately, the Morita therapy is especially effective for patients who pay excessive attention to somatic symptoms or are hypochondriacal, which is applicable for outpatients using a comparatively short interview that can even be performed in nonpsychiatric clinical settings.

    Abstract Objective: Corticosteroids can cause psychiatric symptoms known as corticosteroid-induced psychiatric disorders (CIPDs). Little is known regarding the relationship between intravenous pulse methylprednisolone (IVMP) and CIPDs. Therefore, we aimed to examine the relationship between corticosteroid use and CIPDs in this retrospective study.
    Methods: Patients who were prescribed corticosteroids during their hospitalization at a university hospital and referred to our consultation-liaison service were selected. Patients diagnosed with CIPDs according to the ICD-10 codes were included. The incidence rates were compared between patients receiving IVMP and those receiving any other corticosteroid treatment. The association between IVMP and CIPDs was examined by classifying patients with CIPD into three groups according to the use of IVMP and timing of CIPD onset.
    Results: Of the 14,585 patients who received corticosteroids, 85 were diagnosed with CIPDs, with an incidence rate of 0.6%. Among the 523 patients who received IVMP, the incidence rate of CIPDs was 6.1% (n = 32), which was significantly higher than that in patients receiving any other corticosteroid treatment. Among the patients with CIPDs, 12 (14.1%) developed CIPDs during IVMP, 19 (22.4%) developed CIPDs after IVMP, and 49 (57.6%) developed CIPDs without IVMP. There was no significant difference in the doses at the time of CIPD improvement among the three groups when we excluded one patient whose CIPD improved during IVMP.
    Conclusion: Patients receiving IVMP were more likely to develop CIPDs than those who did not receive IVMP. Furthermore, corticosteroid doses at the time of improvement of CIPDs were constant, regardless of IVMP use.

    Abstract Background: The coronavirus disease 2019 (COVID-19) pandemic has resulted in a total upending of our daily lives. While anxiety and depression were frequently reported among the general population, the pandemic's impact on patients with mental health problems remains unknown.
    Methods: A cross-sectional questionnaire survey involving 1,166 patients was conducted at one psychiatric hospital and one mental health clinic.
    Results: Symptom deterioration was reported in 23% to 34% of the patients and 9% to 20% reported increase in drug dosage. No significant differences were reported in these items among diagnostic categories. Patients with
    Conclusion: One third of patients reported symptom deterioration during the pandemic, which was associated with stress and daily life changes. Patients with good adaptability to environmental changes might resilient against symptom deterioration. Providing continuous support to help patients manage their daily life in this COVID-19 era may minimize the risk of symptom deterioration.

    Abstract Objective: The objective of this study was to investigate the descending neural drive to ankle muscles during gait in stroke patients using a coherence analysis of surface electromyographic (EMG) recordings and the relationships of the drive with clinical functions.
    Methods: EMG recordings of the paired tibialis anterior (TA), medial and lateral gastrocnemius (MG and LG), and TA-LG muscles were used to calculate intramuscular, synergistic, and agonist-antagonist muscle coherence, respectively, in 11 stroke patients and 9 healthy controls. Paretic motor function, sensory function, spasticity, ankle muscle strength, and gait performance were evaluated.
    Results: Paretic TA-TA and MG-LG beta band (15-30 Hz) coherences were significantly lower compared with the non-paretic side and controls. TA-LG beta band coherence was significantly higher on both sides compared with controls. Paretic TA-TA beta band coherence positively correlated with gait speed, and paretic TA-LG beta band coherence negatively correlated with paretic ankle plantar flexor muscle strength.
    Conclusions: The intramuscular and synergistic muscle neural drives were reduced during gait on the paretic side in stroke patients. The agonist-antagonist muscle neural drive was increased to compensate for paretic ankle muscle weakness.
    Significance: Descending neural drive reorganization to agonist-antagonist muscles is important for patients with paretic ankle muscle weakness.

    Abstract Background: Sunlight contains ultraviolet B (UVB) radiation that triggers the production of vitamin D by skin. Vitamin D has widespread effects on brain function in both developing and adult brains. However, many people live at latitudes (about > 40 N or S) that do not receive enough UVB in winter to produce vitamin D. This exploratory study investigated the association between the age of onset of bipolar I disorder and the threshold for UVB sufficient for vitamin D production in a large global sample.
    Methods: Data for 6972 patients with bipolar I disorder were obtained at 75 collection sites in 41 countries in both hemispheres. The best model to assess the relation between the threshold for UVB sufficient for vitamin D production and age of onset included 1 or more months below the threshold, family history of mood disorders, and birth cohort. All coefficients estimated at P ≤ 0.001.
    Results: The 6972 patients had an onset in 582 locations in 70 countries, with a mean age of onset of 25.6 years. Of the onset locations, 34.0% had at least 1 month below the threshold for UVB sufficient for vitamin D production. The age of onset at locations with 1 or more months of less than or equal to the threshold for UVB was 1.66 years younger.
    Conclusion: UVB and vitamin D may have an important influence on the development of bipolar disorder. Study limitations included a lack of data on patient vitamin D levels, lifestyles, or supplement use. More study of the impacts of UVB and vitamin D in bipolar disorder is needed to evaluate this supposition.

    Abstract Objective: Circadian rhythm disruption is commonly observed in bipolar disorder (BD). Daylight is the most powerful signal to entrain the human circadian clock system. This exploratory study investigated if solar insolation at the onset location was associated with the polarity of the first episode of BD I. Solar insolation is the amount of electromagnetic energy from the Sun striking a surface area of the Earth.
    Methods: Data from 7488 patients with BD I were collected at 75 sites in 42 countries. The first episode occurred at 591 onset locations in 67 countries at a wide range of latitudes in both hemispheres. Solar insolation values were obtained for every onset location, and the ratio of the minimum mean monthly insolation to the maximum mean monthly insolation was calculated. This ratio is largest near the equator (with little change in solar insolation over the year), and smallest near the poles (where winter insolation is very small compared to summer insolation). This ratio also applies to tropical locations which may have a cloudy wet and clear dry season, rather than winter and summer.
    Results: The larger the change in solar insolation throughout the year (smaller the ratio between the minimum monthly and maximum monthly values), the greater the likelihood the first episode polarity was depression. Other associated variables were being female and increasing percentage of gross domestic product spent on country health expenditures. (All coefficients: P ≤ 0.001).
    Conclusion: Increased awareness and research into circadian dysfunction throughout the course of BD is warranted.

    Abstract Background: Bipolar disorder is associated with circadian disruption and a high risk of suicidal behavior. In a previous exploratory study of patients with bipolar I disorder, we found that a history of suicide attempts was associated with differences between winter and summer levels of solar insolation. The purpose of this study was to confirm this finding using international data from 42% more collection sites and 25% more countries.
    Methods: Data analyzed were from 71 prior and new collection sites in 40 countries at a wide range of latitudes. The analysis included 4876 patients with bipolar I disorder, 45% more data than previously analyzed. Of the patients, 1496 (30.7%) had a history of suicide attempt. Solar insolation data, the amount of the sun's electromagnetic energy striking the surface of the earth, was obtained for each onset location (479 locations in 64 countries).
    Results: This analysis confirmed the results of the exploratory study with the same best model and slightly better statistical significance. There was a significant inverse association between a history of suicide attempts and the ratio of mean winter insolation to mean summer insolation (mean winter insolation/mean summer insolation). This ratio is largest near the equator which has little change in solar insolation over the year, and smallest near the poles where the winter insolation is very small compared to the summer insolation. Other variables in the model associated with an increased risk of suicide attempts were a history of alcohol or substance abuse, female gender, and younger birth cohort. The winter/summer insolation ratio was also replaced with the ratio of minimum mean monthly insolation to the maximum mean monthly insolation to accommodate insolation patterns in the tropics, and nearly identical results were found. All estimated coefficients were significant at p < 0.01.
    Conclusion: A large change in solar insolation, both between winter and summer and between the minimum and maximum monthly values, may increase the risk of suicide attempts in bipolar I disorder. With frequent circadian rhythm dysfunction and suicidal behavior in bipolar disorder, greater understanding of the optimal roles of daylight and electric lighting in circadian entrainment is needed.
