  • Association of high complement and low immunoglobulins with the clinical symptoms of patients with fibromyalgia

    Open AccessSatoshi Izuno, Masako Hosoi et al.ARTICLEBioPsychoSocial Medicine2025

    BACKGROUND: Fibromyalgia (FM) is a disease characterized by chronic widespread pain concomitant with various symptoms such as fatigue and anxiety. Although chronic inflammation has been implicated in the immunological abnormalities of FM, there are few human studies on complement and immunoglobulins. In this study, we investigated the immunological characteristics of FM patients and the association between their clinical symptoms and immunologica…

  • The Positive and Negative Affect Schedule (Panas)

    Open AccessDorjnambar Balgansuren, Binderiya Bayanmunkh et al.ARTICLEBMC Psychology2025

    The Mongolian PANAS is a psychometrically sound tool for assessing affective states in university students, which supports its use in research and educational settings. However, additional refinement may be needed to enhance its cultural sensitivity and applicability. Future research should explore its use in clinical populations and longitudinal studies to assess its predictive validity over time

    Open AccessTomoe Nishihara, Mao Shibata et al.ARTICLEBioPsychoSocial Medicine2023

    BACKGROUND: Previous studies have shown that patients with Coronavirus Disease 2019 (COVID-19) are likely to be affected by delirium and other psychiatric complications. We aimed to evaluate the relation between COVID-19 vaccination status and referral of patients hospitalized with COVID-19 for consultation-liaison psychiatry services. METHOD: From the medical records used for this retrospective, single hospital-based study, 576 patients were ide…

    Open AccessNobuhiro Nohara, Yukari Yamanaka et al.ARTICLEBioPsychoSocial Medicine2023

    Background The superiority of Enhanced Cognitive Behavior Therapy (CBT-E) with regard to weight gain and improvement of psychopathology of eating disorders for patients with anorexia nervosa (AN) over other psychotherapies and treatment as usual (TAU) has not been demonstrated in randomized controlled trials (RCTs). However, a previous RCT showed that patients with AN whose baseline body mass index (BMI) was less than 17.5 kg/m 2 gained more weig…

    Open AccessTomoe Nishihara, Kazufumi Yoshihara et al.ARTICLEBioPsychoSocial Medicine2023

    BACKGROUND: Psychological distress has been frequently observed in frontline healthcare workers under stress during the coronavirus disease 2019 (COVID-19) epidemic; however, it is unclear if there are differences in the stress and symptoms experienced by staff members who work exclusively in a COVID-19 ward and support staff temporarily deployed to a COVID-19 ward. The present study investigated psychosocial stress specific to the care for patie…

  • Alexithymia characteristics are associated with salience network activity in healthy participants

    Open AccessYuki Motomura, Ayaka Fukuzaki et al.ARTICLEJournal of PHYSIOLOGICAL…2023References: 39

    Background Alexithymia, a personality trait characterized by difficulties in identifying and expressing their emotions despite having a range of emotional experiences, can impact individuals' stress coping mechanisms. While many studies have investigated brain functions associated with specific tasks in relation to emotion processing, research focusing on resting-state brain functions has been limited. Thus, the aim of this study was to investiga…

  • Possible role of the gut microbiota in the pathogenesis of anorexia nervosa

    Open AccessNobuyuki SudoARTICLEBioPsychoSocial Medicine2021

    Anorexia nervosa (AN), an eating disorder, is characterized by extreme weight loss and fear of weight gain. Psychosocial factors are thought to play important roles in the development and progression of AN; however, biological factors also presumably contribute to eating disorders. Recent evidence has shown that the gut microbiota plays an important role in pathogenesis of neuropsychiatric disorders including AN. In this article, we describe the …

    BACKGROUND: Pictorial Representation of Illness and Self Measure (PRISM) is a tool that can be used to visualize and evaluate the burden of suffering caused by an illness. The aim of this study was to identify which aspects of the burden of chronic pain patients are associated with Self/illness separation (SIS), an indicator of the magnitude of suffering. We also examined the effectiveness of PRISM for evaluating changes in the relationships betw…

  • Changes in circulating microRNA after recumbent isometric yoga practice by patients with myalgic encephalomyelitis/chronic fatigue syndrome

    Open AccessShu Takakura, Takakazu Oka et al.ARTICLEBioPsychoSocial Medicine2019

    BACKGROUND: Yoga is a representative mind-body therapy. Our previous studies have demonstrated that isometric yoga (i.e. yoga programs that we developed so individuals can practice yoga poses with a self-adjustable isometric load) reduces the fatigue of patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS); however, the underlying mechanisms remain unclear. Several studies have suggested that the micro-ribonucleic acid (miRNA)…

    Open AccessTakakazu Oka, Tokusei Tanahashi et al.ARTICLEBioPsychoSocial Medicine2018

    BACKGROUND: In a previous randomized controlled trial, we found that sitting isometric yoga improves fatigue in patients with chronic fatigue syndrome (CFS) who are resistant to conventional therapy. The aim of this study was to investigate possible mechanisms behind this finding, focusing on the short-term fatigue-relieving effect, by comparing autonomic nervous function and blood biomarkers before and after a session of isometric yoga. METHODS:…

  • Predictors of successful long-term weight loss maintenance

    Open AccessRyoko Sawamoto, Takehiro Nozaki et al.ARTICLEBioPsychoSocial Medicine2017

    BACKGROUND: Weight regain is a common problem following weight loss intervention, with most people who seek treatment for obesity able to lose weight, but few able to sustain the changes in behavior required to prevent subsequent weight regain. The identification of factors that predict which patients will successfully maintain weight loss or who are at risk of weight regain after weight loss intervention is necessary to improve the current weigh…

METHODS: Two hundred and forty Japanese CHC patients (mean age 62.4 years) were assessed for behavioral patterns (Stress Inventory), QOL (Functional Assessment of Chroni…

  • Life events, emotional responsiveness, and the functional prognosis of patients with rheumatoid arthritis

    Open AccessJun Nagano, Nobuyuki Sudo et al.ARTICLEBioPsychoSocial Medicine2015

    BACKGROUND: Stressors may differently affect human physiological systems according to the host properties relevant to psycho-behavioral processes that the stressors invoke.
