Importance: Recent conceptualizations in Research Domain Criteria have indicated that anhedonia, 1 of 2 core symptoms of depression, which can be treatment resistant, is associated with deficits in the positive valence system, and inaudible high-frequency sound therapy has been shown to enhance reward-related brain circuitry. Hence, cognitive behavioral therapy focusing on the positive valence system enhanced with sound therapy could have a synergistic effect on anhedonia. Objective: To test the augmentation effect of inaudible high-frequency sounds on the efficacy of positive valence system-focused cognitive behavioral therapy to treat anhedonia. Design, Setting, and Participants: In this individual-level allocation, exploratory, single-center randomized superiority pilot trial, patients, therapists, and evaluators will be masked to intervention or placebo assignment. The trial will take place at a national psychiatric referral hospital in Tokyo, Japan, among 44 adult patients with clinically significant anhedonia and moderate to severe depression. Outcomes will be analyzed following the intent-to-treat principle using a repeated-measures mixed model. Intervention: The intervention group will participate in 8 weekly sessions of positive valence system-focused cognitive behavioral therapy with in-session exposure to an inaudible high-frequency sound; the comparison group will undergo cognitive behavioral therapy with in-session exposure to a placebo sound. Main Outcomes and Measures: The primary outcome is anhedonia assessed using the self-reported Snaith-Hamilton Pleasure Scale. The secondary outcome is anhedonia assessed using the clinician-administered version of the Snaith-Hamilton Pleasure Scale. Discussion: Recruitment for this study began in May 2018, and the projected date of final allocation is January 2020. A total of 21 eligible patients were registered for participation as of May 30, 2019. To date, treatments for depression do not guarantee clinically successful outcomes. This pilot trial will provide preliminary evidence of the augmentation effect of high-frequency inaudible sounds on cognitive behavioral therapy for anhedonia. Overall, exposure to an inaudible high-frequency sounds does not require attentional or cognitive effort from either patients or therapists; therefore, results from a future confirmative trial could indicate that cognitive behavioral therapy can be augmented in an effortless manner.

Photoinduced electron transfer (PeT)-based hybridization probe is a linear and quencher-free oligonucleotide (ON) probe for DNA or RNA detection. In this report, we designed and synthesized novel adenosine analogues for PeT-based hybridization probe. In particular, the analogue containing a piperazinomethyl moiety showed effective quenching property under physiological conditions. When the probe containing the analogue was hybridized with a complementary DNA or RNA, the fluorescence increased 3- or 4-fold, respectively, compared to the single-stranded state.

Social anxiety disorder (SAD) is characterized by strong fear and anxiety during social interactions. Although ventrolateral prefrontal cortex (VLPFC) activity in response to emotional stimuli is related to pathological anxiety, little is known about the relationship between VLPFC activity and social anxiety. This study aimed to investigate whether VLPFC activity was involved in SAD and whether VLPFC activity was related to the level of social anxiety. Twenty-four drug-naïve patients with SAD and 35 healthy controls underwent near-infrared spectroscopy (NIRS) scanning while performing a verbal fluency task (VFT). Results indicated that, compared to the healthy controls, the SAD patients exhibited smaller changes of oxygenated hemoglobin (oxy-Hb) concentrations in the VLPFC during the VFT. Furthermore, the right VLPFC activation was negatively correlated with social avoidance. In contrast to the latter, the healthy controls exhibited a positive correlation between changes of oxy-Hb concentrations in the bilateral VLPFC and social fear. Our findings provide evidence for VLPFC dysfunction in SAD, and indicate that the VLPFC dysfunction may contribute to the difference between normal and abnormal social anxiety.

BACKGROUND: The place where a patient experiences his/her first panic attack (FPA) may be related to their agoraphobia later in life. However, no investigations have been done into the clinical features according to the place where the FPA was experienced. In particular, there is an absence of detailed research examining patients who experienced their FPA at home. In this study, patients were classified by the location of their FPA and the differences in their clinical features were explored (e.g., symptoms of FPA, frequency of agoraphobia, and severity of FPA). METHODS: The subjects comprised 830 panic disorder patients who were classified into 5 groups based on the place of their FPA (home, school/office, driving a car, in a public transportation vehicle, outside of home), The clinical features of these patients were investigated. Additionally, for panic disorder patients with agoraphobia at their initial clinic visit, the clinical features of patients who experienced their FPA at home were compared to those who experienced their attack elsewhere. RESULTS: In comparison of the FPAs of the 5 groups, significant differences were seen among the 7 descriptors (sex ratio, drinking status, smoking status, severity of the panic attack, depression score, ratio of agoraphobia, and degree of avoidance behavior) and 4 symptoms (sweating, chest pain, feeling dizzy, and fear of dying). The driving and public transportation group patients showed a higher incidence of co-morbid agoraphobia than did the other groups. Additionally, for panic disorder patients with co-morbid agoraphobia, the at-home group had a higher frequency of fear of dying compared to the patients in the outside-of-home group and felt more severe distress elicited by their FPA. CONCLUSION: The results of this study suggest that the clinical features of panic disorder patients vary according to the place of their FPA. The at-home group patients experienced "fear of dying" more frequently and felt more distress during their FPA than did the subjects in the other groups. These results indicate that patients experiencing their FPA at home should be treated with a focus on the fear and distress elicited by the attack.
RESUMO
The number of suicides in Japan has increased from approximately 22,000 per year in 1988-1997 to over 30,000 per year since then. The number has also increased in Mie Prefecture during this period. According to many reports, suicide attempts are one of the risk factors of suicide. In the present study, we investigated the incidences and circumstances of all suicide cases between 1996 and 2002, focusing in detail on the frequency of suicide attempts and general differences in the frequency of all suicide cases. During the 7 years, 1979 male and 969 female suicides were reported to Mie Prefectural Police Headquarters. During the test period, there were suicide attempts in 13.4% of all suicidal cases, 10.7% for men and 18.9% for women. The average age was 48.98 years (SD 17.68), 47.07 years (SD 16.32) for men, and 51.19 years (SD 18.89) for women. Among men, we discovered the risk factors of suicide attempts in completed suicides, which were "single time" of suicide attempts, "living with family" for the family constitution, and "visiting treatment" of the admission statuses. Among women, the risk factors were "living with family" and "visiting treatment". We must pay attention to those risk factors.

The number of suicides in Japan has increased from approximately 22 000 per year from 1988 to 1997 to >30 000 per year since 1998. Likewise, the number of suicides has been increasing in Mie Prefecture. The purpose of the present study was to examine the incidence of and circumstances surrounding all suicide cases during 1996-2002 in Mie Prefecture and to compare the data with those from 1989 to 1995. In Mie Prefecture, the age-specific suicide rate during the second 7-year period included marked increases among men aged 50-59 and 60-69 years. Among women, the age-specific suicide rate increased with age during both 7-year periods. During the second period, psychiatric disorders as causative factors increased in all generations. They were especially important for women of the younger generation, whereas economic problems were the most common causative factor among men aged 40-64. Physical illness as a causative factor in suicide was high among the elderly, but among the other age groups this factor trailed behind economic difficulties for men and psychiatric disorders for women. To prevent suicide, social cooperation as well as a plenitude of visiting nurses and psychiatric care is required, and early detection and treatment are also important.
