Siderophore synthetase-receptor gene coevolution reveals habitat- and pathogen-specific bacterial iron interaction networks.

Bacterial social interactions play crucial roles in various ecological, medical, and biotechnological contexts. However, predicting these interactions from genome sequences is notoriously difficult. Here, we developed bioinformatic tools to predict whether secreted iron-scavenging siderophores stimulate or inhibit the growth of community members.

Prevalence of probable posttraumatic stress disorder and determination of its relationship with everyday functioning in children and adolescents by using generalized estimating equations.

Introduction: We investigated the prevalence rates for probable PTSD and used generalized estimating equations to identify risk factors for probable PTSD in children and adolescents exposed to the Lushan earthquake.

Methods: A total of 1623 participants completed 3 assessments, including the Children's Revised Impact of Event Scale, at 2 weeks, 3, and 6 months after experiencing the Lushan earthquake. Additionally, demographic variables and variables related to everyday functioning were evaluated at 2 weeks after the earthquake via a self-constructed questionnaire.

Prevalence and risk factors of posttraumatic stress disorder among teachers 3 months after the Lushan earthquake: A cross-sectional study.

Teachers and students often suffer from the same disaster. The prevalence of PTSD in students has been given great attention. However, in acting as mentors to students and their families, teachers are more likely to have vicarious and indirect exposure via hearing stories of their aftermath and witnessing the consequences of traumatic events.

Prevalence and Predictors of Somatic Symptoms among Child and Adolescents with Probable Posttraumatic Stress Disorder: A Cross-Sectional Study Conducted in 21 Primary and Secondary Schools after an Earthquake.

Purpose: To explore the prevalence rates and predictors of somatic symptoms among child and adolescent survivors with probable posttraumatic stress disorder (PTSD) after an earthquake.

Methods: A total of 3053 students from 21 primary and secondary schools in Baoxing County were administered the Patient Health Questionnaire-13 (PHQ-13), a short version of PHQ-15 without the two items about sexuality and menstruation, the Children's Revised Impact of Event Scale (CRIES), and the self-made Earthquake-Related Experience Questionnaire 3 months after the Lushan earthquake.

Results: Among child and adolescent survivors, the prevalence rates of all somatic symptoms were higher in the probable PTSD group compared with the controls.

Posttraumatic stress disorder and somatic symptoms among child and adolescent survivors following the Lushan earthquake in China: A six-month longitudinal study.

Objective: To explore somatic conditions in a sample of 2299 child and adolescent survivors of an earthquake and their relationship to posttraumatic stress disorder (PTSD) symptoms.

Methods: The Children's Revised Impact of Event Scale, the Patient Health Questionnaire (PHQ)-13 scale, a short version of PHQ-15 scale that omits two items involving sexual pain/problems and menstrual problems, and a project-developed questionnaire were administered to participants three and six months after the earthquake.

Results: Among child and adolescent survivors, the prevalence rates of probable PTSD were 37.
