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]

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. DLS-STW 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. Index Terms--Grating interferometer head, hard disk drive (HDD), laser scale, servotrack writing.

Objective: Electroconvulsive therapy (ECT) is a reasonable option for intractable depression or schizophrenia, but a mechanism of action has not been established. One credible hypothesis is related to neural plasticity. Three genes (Oct4, Sox2, c-Myc) involved in the induction of induced pluripotent stem (iPS) cells are Wnt-target genes, which constitute a key gene group involved in neural plasticity through the TCF family. Klf4 is the other gene among Yamanaka's four transcription factors, and increases in its expression are induced by stimulation of the canonical Wnt pathway., Methods: We compared the peripheral blood gene expression of the four iPS genes (Oct4, Sox2, c-Myc, and Klf4) before and after modified ECT (specifically ECT with general anesthesia) of patients with intractable depression (n=6) or schizophrenia (n=6). Using Thymatron ten times the total bilateral electrical stimulation was evoked., Results: Both assessments of the symptoms demonstrated significant improvement after mECT stimulation. Expression of all four genes was confirmed to increase after initial stimulation. The gene expression levels after treatment were significantly different from the initial gene expression in all twelve cases at the following treatment stages: at the 3rd mECT for Oct4; at the 6th and 10th mECT for Sox2; and at the 3rd, 6th and 10th mECT for c-Myc., Conclusion: These significant differences were not present after correction for multiple testing; however, our data have the potential to explain the molecular mechanisms of mECT from a unique perspective. Further studie should be conducted to clarify the pathophysiological involvement of iPS-inducing genes in ECT.
