The Somatic Symptom Disorder - B Criteria Scale (SSD-12): Factorial structure, validity and population-based norms.

2017

The Somatic Symptom Disorder - B Criteria Scale (SSD-12) assesses the psychological features of DSM-5 Somatic Symptom Disorder (SSD). The present study investigates the dimensionality and psychometric properties in a general population sample and provides norm values.Test dimensionality was evaluated via confirmatory factor analysis and nonparametric item response theory. Correlational analyses and logistic regression models based on related measures (SSS 8, PHQ-2, GAD-2, Health Care Utilization) were used to derive predictive validity. Age and gender specific norms were derived via quantile regression.The SSD-12 has good item characteristics and excellent reliability (Cronbach's α=0.95). C…

Ferroptosis Meets Cell–Cell Contacts

2021

Ferroptosis is a regulated form of cell death characterized by iron dependency and increased lipid peroxidation. Initially assumed to be selectively induced in tumour cells, there is increasing evidence that ferroptosis plays an important role in pathophysiology and numerous cell types and tissues. Deregulated ferroptosis has been linked to human diseases, such as neurodegenerative diseases, cardiovascular disorders, and cancer. Along these lines, ferroptosis is a promising pathway to overcoming therapy resistance of cancer cells. It is therefore of utmost importance to understand the cellular signalling pathways and the molecular mechanisms underlying ferroptosis regulation, including cont…

Early Adverse Effects of Behavioural Preventive Strategies During the COVID-19 Pandemic in Germany: An Online General Population Survey

2022

Background Quarantine and physical distancing represent the two most important non-pharmaceutical actions to contain the COVID-19 pandemic. Comparatively little is known about possible adverse consequences of these behavioural measures in Germany. This study aimed at investigating potential early adverse effects associated with quarantine and physical distancing at the beginning of the countrywide lockdown in Germany in March 2020. Method Using a cross-sectional online survey (N = 4,268), adverse consequences attributed to physical distancing, symptoms of psychopathology, and sociodemographic variables were explored in the total sample as well as in high-risk groups (i.e., people with a ph…

Überprüfung der zeitlichen Stabilität medizinisch nicht erklärter Beschwerden und somatoformer Störungen vor dem Hintergrund unterschiedlicher Diagno…

2011

OBJECTIVE: The aim of this study was to determine and to compare the stability of medically unexplained symptoms and somatoform disorders within the context of different diagnostic concepts (SSI4/6, DSM-IV, DSM-V). METHOD: In a 2-stage follow-up study, 620 consecutive patients were first of all screened using the PHQ-15 questionnaire. In the second stage, 308 selected persons were then interviewed in detail. 12 months later, 89,9% of participants could be interviewed again. RESULTS: Medically unexplained symptoms and somatoform disorders showed weak stability coefficients. In regard to Complex Somatic Symptom Disorder (DSM-V), the prevalence rates were smaller than expected. Within a year, …

Quejas somáticas, conciencia emocional e inadaptación en población escolar

2015

Resumen: Introducción: Las quejas somáticas son frecuentes en la infancia. La investigación ha puesto de manifiesto su relación con la conciencia emocional y la inadaptación. El estudio tuvo 3 objetivos: 1) analizar la prevalencia de las quejas somáticas; 2) explorar las relaciones entre las variables evaluadas: quejas somáticas, diferenciar emociones, comunicar verbalmente emociones, no esconder emociones, conciencia corporal, atender emociones de otros, análisis de las propias emociones, inadaptación personal, inadaptación social, inadaptación familiar e inadaptación escolar, y 3) identificar variables predictoras de las quejas somáticas. Pacientes y métodos: Los participantes, selecciona…

Psychopathology, Dissociation and Somatic Symptoms in Adolescents Who Were Exposed to Traumatic Experiences

2018

Background: The direct and long-term effects of children’s exposure to traumatic events can be seen in a complex continuum, based first of all on the type of trauma. Children’s reactions to trauma may have different manifestations from the clinical picture of the PTSD, exhibiting dissociative, somatic, depressive or anxiety symptoms, and/or disruptiveness. Aim: we conducted a cross-sectional study in a psychiatric patients sample to determine the extent to which complex trauma history is associated with disease-related characteristics (diagnosis, dissociative symptoms, somatic symptomatology, impairment degree). Methods: We have enrolled 107 subjects, aged between 12 and 18 years, who conse…

Neuroimaging correlates of insight in non-affective psychosis: A systematic review and meta-analysis.

2022

Abstract Objective Neurological correlates of impaired insight in non-affective psychosis remain unclear. This study aimed to review and meta-analyze the studies assessing the grey matter volumetric correlates of impaired insight in non-affective psychosis. Methods This study consisted of a systematic review of 23 studies, and a meta-analysis with SDM-PSI of the 11 studies that were whole-brain and reported maps or peaks of correlation of studies investigating the grey matter volumetric correlates of insight assessments of non-affective psychosis, PubMed and OVID datasets were independently reviewed for articles reporting neuroimaging correlates of insight in non-affective psychosis. Qualit…

Effect of methyl jasmonate in gene expression, and in hormonal and phenolic profiles of holm oak embryogenic lines before and after infection with Ph…

2022

The dieback syndrome affecting Quercus ilex and other oak species impels the search for tolerant plant genotypes, as well as methods of plant immunization against such infections. Elicitation treatments can be an effective strategy to activate plant defense response and embryogenic lines represent a promising tool to generate new tolerant genotypes and also to study early markers involved in defense response. The aim of the presented work was to investigate changes in gene expression, and in hormonal and phenolic profiles induced in three holm oak embryogenic lines (ELs) elicited with methyl jasmonate (MeJA) before and after infection with the oomycete Phytophthora cinnamomi, which is the m…

Receiver-operating characteristic curves for somatic cell scores and California mastitis test in Valle del Belice dairy sheep.

2013

Using receiver-operating characteristic (ROC) curve methodology this study was designed to assess the diagnostic effectiveness of somatic cell count (SCC) and the California mastitis test (CMT) in Valle del Belice sheep, and to propose and evaluate threshold values for those tests that would optimally discriminate between healthy and infected udders. Milk samples (n = 1357) were collected from 684 sheep in four flocks. The prevalence of infection, as determined by positive bacterial culture was 0.36, 87.7% of which were minor and 12.3% major pathogens. Of the culture negative samples, 83.7% had an SCC < 500,000/mL and 97.4% had <1,000,000 cells/mL. When the associations between SC score (SC…
