Not only Body Weight Perception but also Body Mass Index is Relevant to Suicidal Ideation and Self-Harming Behavior in Japanese Adolescents

Whether a low body mass index (BMI) is directly associated with a high risk of suicidal ideation or self-harming behavior in adolescents is still inconclusive. This study has, therefore, evaluated the relevance of BMI to suicidal ideation and self-harming behavior after controlling for body weight perception (BWP) and other potential confounding factors. BMI, BWP, suicidal ideation, and self-harming behavior were all assessed using a self-report questionnaire administered to 18,104 Japanese adolescents. Potential confounding factors were also evaluated. The data were then analyzed using bi-variate and multivariate logistic regression. Low BMI was associated with suicidal ideation and deliberate self-harm when controlling for sex, age, drug use, emotional distress, and BWP. Low BMI may be an independent risk factor for suicidal ideation and deliberate self-harming behavior in Japanese adolescents.ArticleJOURNAL OF NERVOUS AND MENTAL DISEASE. 200(4):305-309 (2012)journal articl

Fear of negative evaluation is associated with delusional ideation in non-clinical population and patients with schizophrenia

Purpose: A number of recent studies suggest that delusions may be explained as a continuum from normal beliefs. Fear of negative evaluation from others (FNE) is one of potential factors that might describe this psychological process of delusions. Methods: In order to examine whether FNE is associated with delusional ideation in both non-clinical population and patients with schizophrenia, two sets of data [from a non-clinical student sample (n = 282) and from patients with schizophrenia (n = 117)] were collected to examine whether Brief Fear of Negative Evaluation Scale (BFNE) score and the 21-item Peters Delusions Inventory (PDI-21) score were associated with each other. Linear regression analyses were carried out to assess if the BFNE score still remained associated with the PDI-21 scores once the confounding effects of depression were controlled. RESULTS: BFNE scores were significantly related to PDI-21 scores in both non-clinical [Pearson product-moment correlation coefficient (r) = 0.37, 95% confidence Interval (CI) = 0.25-0.48] and patient (r = 0.33, 95% CI = 0.14-0.49) samples. These associations were still significant when confounding effects of depression were controlled. Standardised coefficients for the BFNE scores in the linear regression model were 0.21 in the student sample and 0.19 in the clinical sample. Conclusions: FNE was associated with delusional ideation both in non-clinical population and in patients with schizophrenia. FNE might be a potential target for both pharmacological and psychological interventions for patients with delusions

A semi-structured clinical interview for psychosis sub-groups (SCIPS): development and psychometric properties

BACKGROUND: Clinical sub-groups of schizophrenia, namely drug related, traumatic, anxiety and stress sensitivity sub-types, have been proposed for use in research, training and practice. They were developed on the basis of clinical observation but have not yet been used in research or clinical practice to any great extent. AIMS: To develop a semi-structured clinical interview for psychosis sub-groups (SCIPS) and determine the best diagnostic criteria with the highest inter-rater reliability, test-retest reliability and concurrent validity for sub-grouping patients with schizophrenia according to a newly developed classification scheme. METHODS: The SCIPS was developed based upon discussion with the clinician researchers who had developed and were using the sub-groups. Kappa coefficients were calculated between two independent diagnostic assessments with the SCIPS (for inter-rater reliability and test-retest reliability, n = 20) and between the SCIPS diagnosis and the sub-groupings as determined independently with highest achievable validity (for concurrent validity, n = 21) for patients with schizophrenia. These inter-rater reliability and concurrent validity were compared among five different sets of diagnostic criteria to determine which was most reliable and valid. RESULTS: A set of diagnostic criteria with the highest inter-rater reliability and concurrent validity was determined. Kappa coefficients (95% confidence interval) for the inter-rater reliability and concurrent validity were 0.93 (0.66-1.20) and 0.73 (0.47-1.00), respectively, with these diagnostic criteria. CONCLUSIONS: The SCIPS is a promising tool with which to sub-group patients with schizophrenia according to this recently developed classification scheme. The semi-structured interview achieves acceptable inter-rater and test-retest reliability and concurrent validity

Semipermanent Volumization by an Absorbable Filler: Onlay Injection Technique to the Bone

Background: Hyaluronic acid (HA) fillers have become the most popular tool for wrinkle treatment and volumization, although HA is generally absorbed within 6–12 months and requires repeated treatments to maintain the effects. Methods: HA was injected onto the bone for volumization with a small 30-gauge needle to examine the long-lasting effects. Of the 63 Japanese patients with 97 treated sites followed up more than 12 months, 51 had HA injections for cosmetic purposes and 12 were treated for reconstructive volumization of facial deformity such as localized scleroderma and postsurgical bony deformity. Treated sites included the forehead, temple, nasal root, mentum, tear trough, and infraorbital sulcus. Results: After long-term follow-up (12–93 months, mean = 21.6), persistent volumizing effects were observed in most patients. In fact, 86.6% of the treated sites showed >50% volume retention and 49.5% showed >75% retention. Magnetic resonance imaging analyses revealed that the injected space was well maintained, capsulated, and filled with heterogeneous content. Magnetic resonance imaging quantitative T2 maps indicated that much of the injected HA was replaced with other materials. Together with clinical inspection, these findings suggest that onlay injection of HA on the bone induced formation of capsule, fibrosis, and/or calcification/ossification, which contributed to persistent volumization. Conclusions: Semipermanent volumizing effects can be achieved by HA injection if the target area has an underlying bony floor. Periosteal stem cells may be activated by HA injection and may contribute to persistent volumizing effects. This treatment may be a much less invasive alternative to fat or bone grafting
