A servotrack writing (STW) system using dual laser scales (DLSs) has been developed. Two very small and lightweight laser scales are mounted on both the head arm and spindle motor, respectively, detecting the arm position and clock signal by the grating interferometer head. DLSSTW is a drive-level servotrack writer that eliminates the need for a clean room. A 5-nm step VCM control has been achieved by using a mechanically improved prototype small hard disk drive.

Aim: Live two‐way video, easily accessible from home via smartphones and other devices, is becoming a new way of providing psychiatric treatment. However, lack of evidence for real‐world clinical setting effectiveness hampers its approval by medical insurance in some countries. Here, we conducted the first large‐scale pragmatic, randomized controlled trial to determine the effectiveness of long‐term treatment for multiple psychiatric disorders via two‐way video using smartphones and other devices, which are currently the primary means of telecommunication. Methods: This randomized controlled trial compared two‐way video versus face‐to‐face treatment for depressive disorder, anxiety disorder, and obsessive‐compulsive disorder in the subacute/maintenance phase during a 24‐week period. Adult patients with the above‐mentioned disorders were allocated to either a two‐way video group (≥50% video sessions) or a face‐to‐face group (100% in‐person sessions) and received standard treatment covered by public medical insurance. The primary outcome was the 36‐Item Short‐Form Health Survey Mental Component Summary (SF‐36 MCS) score. Secondary outcomes included all‐cause discontinuation, working alliance, adverse events, and the severity rating scales for each disorder. Results: A total of 199 patients participated in this study. After 24 weeks of treatment, two‐way video treatment was found to be noninferior to face‐to‐face treatment regarding SF‐36 MCS score (48.50 vs 46.68, respectively; p < 0.001). There were no significant differences between the groups regarding most secondary end points, including all‐cause discontinuation, treatment efficacy, and satisfaction. Conclusion: Two‐way video treatment using smartphones and other devices, was noninferior to face‐to‐face treatment in real‐world clinical settings. Modern telemedicine, easily accessible from home, can be used as a form of health care. [ABSTRACT FROM AUTHOR]

Background: Thirty-three Japanese children and adolescents diagnosed with an anxiety disorder participated in individual or group Cognitive Behaviour Therapy (CBT) that was modelled after evidence-based intervention programs developed in Western countries. Method: The treatment consisted of: (a) building rapport and education; (b) identifying emotions and recognizing cognitive self-talk; (c) challenging anxious self-talk; (d) developing an anxiety hierarchy and in vivo exposures; and (e) planning for future challenges. Results: Three months following treatment, 20 of the 33 children and adolescents (60.91%) no longer met criteria for their principal anxiety disorders and 16 (48.48%) were free from all anxiety disorders. Self-reported anxiety, depression, and cognitive errors also decreased significantly from pre- to post-treatment and these gains were maintained at 3-month follow-up. For the most part, similar outcomes were found in both the group and individual formats of CBT. Conclusions: This study provides preliminary support for the transportability of CBT in both an individual and group format to Japan. [ABSTRACT FROM PUBLISHER]

Introduction: The search for objective biomarkers of psychiatric disorders has a long history. Despite this, no universally accepted instruments or methods to detect biomarkers have been developed. One potential exception is near-infrared spectroscopy, although interpreting the measures of blood flow recorded with this technique remains controversial. In this study, we aimed to investigate the relationship between recorded blood flow and depression severity assessed using the Hamilton depression scale in patients with various psychiatric disorders.Methods: Enrolled patients (n=43) had DSM-IV diagnoses of major depressive disorder (n=25), bipolar disorder I (n=5), schizophrenia (n=3), dysthymic disorder (n=3), psychotic disorder (n=3), panic disorder (n=2), and Obsessive Compulsive Disorder (n=2). The verbal fluency task was administered during blood flow recording from the frontal and temporal lobes.Results: We found that severity of depression was negatively correlated with the integral value of blood flow in the frontal lobe, irrespective of psychiatric diagnosis (F=5.94, p=0.02).Discussion: Our results support blood flow in the frontal lobe as a potential biomarker of depression severity across various psychiatric disorders.Limitation: Limited sample size, no replication in the second set.

The COVID-19 pandemic has had a profound impact on the mental health of people around the world. Anxiety related to infection, stress and stigma caused by the forced changes in daily life have reportedly increased the incidence and symptoms of depression, anxiety disorder and obsessive-compulsive disorder. Under such circumstances, telepsychiatry is gaining importance and attracting a great deal of attention. However, few large pragmatic clinical trials on the use of telepsychiatry targeting multiple psychiatric disorders have been conducted to date. The targeted study cohort will consist of adults (>18 years) who meet the DSM-5 diagnostic criteria for either (1) depressive disorders, (2) anxiety disorders, or (3) obsessive-compulsive and related disorders. Patients will be assigned in a 1:1 ratio to either a "telepsychiatry group" (at least 50% of treatments to be conducted using telemedicine, with at least one face-to-face treatment [FTF] within six months) or an "FTF group" (all treatments to be conducted FTF, with no telemedicine). Both groups will receive the usual treatment covered by public medical insurance. The study will utilize a master protocol design in that there will be primary and secondary outcomes for the entire group regardless of diagnosis, as well as the outcomes for each individual disorder group. This study will be a non-inferiority trial to test that the treatment effect of telepsychiatry is not inferior to that of FTF alone. This study will provide useful insights into the effect of the COVID-19 pandemic on the practice of psychiatry. jRCT1030210037, Japan Registry of Clinical Trials (jRCT). [ABSTRACT FROM AUTHOR]
