We conducted a systematic review evaluating the efficacy of rivastigmine augmentation for treatment-refractory posttraumatic stress disorder (PTSD). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. The databases Ovid MEDLINE, PubMed, CINAHL, and EMBASE were searched using key words: 'rivastigmine' OR 'Exelon' OR 'rivastigmine augmentation' OR 'Exelon augmentation' AND 'posttraumatic stress disorder*' OR 'post-traumatic stress disorder*' OR 'PTSD' OR 'combat disorder*' OR 'post-traumatic symptoms'. The asterisk specified plural forms of the relevant word. Four papers were identified, comprising one double-blind randomised controlled trial, one non-controlled open trial, one case series (presenting three case studies), and one paper with two case studies. The randomised controlled trial found no statistically significant difference in efficacy, using the PTSD CheckList-Military Version as the relevant outcomes measure, between the active add-on rivastigmine interventions and placebo or treatment as usual. The open trial, although reporting relatively positive outcomes, had a weak study design and lacked reporting of key information, including participant sex and age and pre-rivastigmine PTSD measures. The assessment of efficacy was based on participants' reporting of subjective benefits, and clinician-rating using a Clinical Global Impression, rather than established PTSD assessments scales. Although the five case studies reported improvement in PTSD symptoms, there were confounding factors and limitations in clinical and demographic data, warranting caution regarding attributed benefits. There is a lack of methodologically robust evidence supporting the efficacy of add-on rivastigmine for the treatment of refractory PTSD. Additional research may help in further evaluating its possible clinical efficacy.

Background: There is evidence suggesting that autistic traits are associated with schizotypal traits. This study examined the factor structure of the Autism Spectrum Quotient 10 (AQ-10) and its associations with schizotypal traits (measured by the Schizotypal Personality Questionnaire-Brief [SPQ-B]) in a cohort of Chinese adolescents and young adults.

Methods: Invitation letters, stratified by locations and housing types, were randomly sent to individuals aged 15 to 24 years for participation. Assessments were made using face-to-face or online interviews. Autistic traits were assessed using the Chinese version of the AQ-10. Schizotypal personality traits were assessed using the Chinese version of the 22-item SPQ-B.

Results: In total, 395 male and 536 female participants (mean age, 19.93 years) were recruited between July 2020 and May 2021. Exploratory factor analysis of the AQ-10 yielded three factors (theory of mind, task switching, and attention deficits) explaining 55.11% of the total variance. Autistic traits were positively correlated with schizotypal traits of disorganised features (r = 0.21, p < 0.001), interpersonal relationship deficits (r = 0.19, p < 0.001), and cognitive-perceptual deficits (r = 0.11, p = 0.001).

Conclusion: In Chinese adolescents and young adults, autistic traits, especially task switching and attention deficits (compared with theory of mind) are more closely correlated with schizotypal personality traits. Disentangling the overlapping and diametrical structure of autistic traits and schizotypal traits may help understand their aetiologies, assessment, and interventions.

Background: Asthma is a common respiratory disease in children. Family factors play a role in its incidence and severity. This study investigated the effect of parental psychological flexibility, parental psychological adjustment to the child's illness, and parental psychological distress on the severity of asthma symptoms of children through mediating child anxiety.

Methods: A total of 216 parents of children with asthma were asked to complete the Acceptance and Action Questionnaire, the Parent Experience of Child Illness, the Depression, Anxiety and Stress Scale - 21 Items, and the parent-report Spence Children's Anxiety Scale. Severity of asthma symptoms was assessed by spirometry.

Results: The highest path coefficient was between parental psychological flexibility and the severity of paediatric asthma symptoms (β = 0.34). Parental psychological distress was found to affect the severity of asthma symptoms of children (β = -0.21) and also mediate child anxiety and then affect the severity of asthma symptoms of children (β = -0.25).

Conclusion: Parental psychological flexibility, parental psychological adjustment to the child's illness, and parental psychological distress had significant effects on the severity of asthma symptoms of children through mediating child anxiety.
