Estimating Depressive Symptom Class from Voice.

Voice-based depression detection methods have been studied worldwide as an objective and easy method to detect depression. Conventional studies estimate the presence or severity of depression. However, an estimation of symptoms is a necessary technique not only to treat depression, but also to relieve patients' distress.

Detection of Major Depressive Disorder Based on a Combination of Voice Features: An Exploratory Approach.

In general, it is common knowledge that people's feelings are reflected in their voice and facial expressions. This research work focuses on developing techniques for diagnosing depression based on acoustic properties of the voice. In this study, we developed a composite index of vocal acoustic properties that can be used for depression detection.

What is necessary to shorten the operative time in initial introduction of robotic gastrectomy for gastric cancer?

Introduction: Robotic gastrectomy (RG) is a good alternative to laparoscopic gastrectomy, as it improves treatment outcomes and reduces the burden of technical difficulties; however, prolonged operative time may be a disadvantage. This study aimed to identify measures to shorten the operative time during the initial introduction of RG at an institution.

Methods: We assessed 33 patients with gastric cancer who underwent radical distal gastrectomy with Billroth-I reconstruction and divided them into three groups: laparoscopic distal gastrectomy (LDG), robotic distal gastrectomy in the early phase (RDG-E), and in the late phase (RDG-L).

Performance Evaluation of a Voice-Based Depression Assessment System Considering the Number and Type of Input Utterances.

It is empirically known that mood changes affect facial expressions and voices. In this study, the authors have focused on the voice to develop a method for estimating depression in individuals from their voices. A short input voice is ideal for applying the proposed method to a wide range of applications.

Evaluation of emotional arousal level and depression severity using voice-derived sound pressure change acceleration.

In this research, we propose a new index of emotional arousal level using sound pressure change acceleration, called the emotional arousal level voice index (EALVI), and investigate the relationship between this index and depression severity. First, EALVI values were calculated from various speech recordings in the interactive emotional dyadic motion capture database, and the correlation with the emotional arousal level of each voice was examined. The resulting correlation coefficient was 0.

Effects of long- and short-term experiences on stress during identification works of dead bodies: Rapid stress level measurement using voice.

Objective: The mental health issues of personnel dealing with the deceased at times of disasters is a problem and techniques are needed that allow for real-time, easy-to-use stress checks. We have studied techniques for measuring mental state using voice analysis which has the benefit of being non-invasive, easy-to-use, and can be performed in real-time. For this study, we used voice measurement to determine the stress experienced during body identification training workshops for dentists.

Evaluation of the Severity of Major Depression Using a Voice Index for Emotional Arousal.

Recently, the relationship between emotional arousal and depression has been studied. Focusing on this relationship, we first developed an arousal level voice index (ALVI) to measure arousal levels using the Interactive Emotional Dyadic Motion Capture database. Then, we calculated ALVI from the voices of depressed patients from two hospitals (Ginza Taimei Clinic (H1) and National Defense Medical College hospital (H2)) and compared them with the severity of depression as measured by the Hamilton Rating Scale for Depression (HAM-D).

Effectiveness of a Voice-Based Mental Health Evaluation System for Mobile Devices: Prospective Study.

Background: We developed a system for monitoring mental health using voice data from daily phone calls, termed Mind Monitoring System (MIMOSYS), by implementing a method for estimating mental health status from voice data.

Objective: The objective of this study was to evaluate the potential of this system for detecting depressive states and monitoring stress-induced mental changes.

Methods: We opened our system to the public in the form of a prospective study in which data were collected over 2 years from a large, unspecified sample of users.

Role of the uridine/cytidine kinase 2 mutation in cellular sensitiveness toward 3'-ethynylcytidine treatment of human cancer cells.

A nucleosidic medicine, 1-(3-C-ethynyl-β-D-ribo-pentofuranosyl)cytosine [3'-ethynylcytidine (ECyd)], is a potent inhibitor of RNA polymerase I and shows anticancer activity to various human solid tumors in vitro and in vivo. ECyd is phosphorylated to 3'-ethyntlcytidine 5'-monophosphate by uridine/cytidine kinase 2 (UCK2) and subsequently further to diphosphate and triphosphate (3'-ethyntlcytidine 5'-diphosphate, 3'-ethyntlcytidine 5'-triphosphate). 3'-Ethyntlcytidine 5'-triphosphate is an active metabolite that can inhibit RNA polymerase I competitively, causing cancer cell death.

A somatostatin analogue, octreotide, ameliorates intestinal ischemia-reperfusion injury through the early induction of heme oxygenase-1.

Background: Intestinal damage after ischemia followed by revascularization, referred to as "ischemia-reperfusion (I/R) injury," is a devastating complication that can occur after acute superior mesenteric obstruction, or after both elective and emergent abdominal aortic surgery. Once an entire layer of intestine is involved in severe ischemia, the mortality rate reaches 90%; no effective medical treatment has been reported to date. Here, we demonstrate that a somatostatin analogue, octreotide, but not a free-radical scavenger, MCI-186, prevented death due to surgically induced intestinal I/R injury in rats.

Long-term Results of Reconstructive Surgery for the Unilateral Aortoiliac Occlusive Disease and Future Risks of Contralateral Iliac Events.

Objective: Our experience with unilateral iliac reconstructive surgery was retrospectively reviewed, and the long-term patency and the morphological information was disclosed. In addition, the prognosis of contralateral iliac artery was examined, because future contralateral iliac events seem to be important for durability of unilateral iliac revascularizations.

Materials And Methods: 148 patients (mean age, 66.

[Intestinal tuberculosis of the terminal ileum causing obstructive ileus and tuberculous peritonitis and presenting numerous peritoneal small red nodules: a case report].

A 38-year-old woman suffering from lower abdominal pain was referred to our hospital. Abdominal computed tomography showed marked thickening of the terminal ileum to the cecum, localized collection of ascites, and multiple mesenteric lymphadenopathy. A barium contrast small bowel series showed solitary severe stenosis of the terminal ileum with marked swelling of the ileocecal valve, where colonoscopy could not pass through, suggesting that ileal stenosis was caused by intestinal tuberculosis.

Treatment of solitary iliac aneurysms: clinical review of 28 cases.

Purpose: The clinical characteristics and long-term results of patients with solitary iliac aneurysms (SIAs) were investigated.

Methods: 28 consecutive patients who underwent repair of SIAs between 1985 and 2004 were reviewed retrospectively, and compared with those of 536 patients who underwent elective repair of an abdominal aortic aneurysm (AAA) during the same period.

Results: The incidence of SIAs among all aorto-iliac aneurysms was 5.
