Objective: Emotional stress reactivity may be a mediating factor in the association between trauma and psychosis. This review aimed to i) identify, summarise and critically evaluate the link between emotional stress reactivity and psychotic experiences ii) examine evidence for a ‘dose-response’ relationship between stress reactivity and psychosis in the wider psychosis phenotype (i.e. sub-clinical symptoms).Method: Electronic database searches (PsychINFO, MEDLINE, EMBASE) were conducted for studies which investigated the link between stress reactivity and psychosis, psychotic symptoms, or a vulnerability to developing psychosis (wider phenotype). Cross-sectional, experimental and experience sampling method study designs were eligible for inclusion. Results: 45 eligible articles were identified (N participants= 8830). Meta-analysis (k=4, n=383) showed increases in emotional stress reactivity was associated with higher negative affect in response to event-related stress, in those with psychosis compared to controls (mean difference in beta coefficients = 0.05, 95% CI 0.02 to 0.08, p=0.004). However, this difference was small with a considerable degree of heterogeneity (p=.001, I² = 81%) so results should be interpreted with caution. Narrative synthesis showed that increased emotional stress reactivity was associated with psychosis and subclinical psychotic experiences across all study designs, however, findings were inconsistent across studies. Conclusions: The results show emotional stress reactivity is associated with both clinical and subclinical psychosis symptoms. Overall, the evidence suggests that the link between emotional stress reactivity and psychosis and emotional stress reactivity is plausible mediator between trauma and psychosis. Further longitudinal research is needed to assess this.

IntroductionOxytocin has been related to traumas and sociability.ObjectiveTo do a systematic review on the relationship between oxytocin and early (ET), current trauma (CT) and PTSD.MethodsThe Pubmed, Psycinfo, Web of Science, Lilacs and Scielo database were researched until to April 2016, using the keywords: oxytocin, early trauma, childhood maltreatment, emotional trauma, emotional stress, neglect, adversity, sexual abuse, emotional abuse, physical abuse and PTSD, and Boolean operators. We used a priori protocol based on PRISMA to select observational and quasi/experimental studies in both gender subjects, who suffer ET, CT, or PSTD. A full review was done, and meta-analysis was carried out when possible to estimate the strength of the association. Strobe, trend and consort statements were used for qualitative assessment.ResultsTwenty-eight studies where included:15 observational, 3 quasi/experimental and 10 RCT. Quality assessment was 60–70%. Due heterogeneity between studies we analysed them in four groups. Meta/analysis of studies of oxytocin endogenous concentration showed a negative correlation with ET (r = -0.35; 95%CI = -0.46/–0.22). Association studies of genetic polymorphism of oxytocin gene receptor (rs53576) showed that subjects with ET, CT and GG genotype had higher vulnerability to develop later psychopathology (P < 0.05). Quasi/experimental studies measuring pre/post oxytocin concentration after a stress reactivity test in subject with ET, CT or PTSD showed any significant results. Finally, RCT studies showed that acute administration of oxytocin increased the levels of anxiety and flashback in subjects with CT; and decreased in PTSD or ET. These results were in parallel with brain and connectivity activation.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The purpose of the systematic review and meta-analysis was to determine if low-ratio n-6/n-3 long-chain polyunsaturated fatty acid (PUFA) supplementation affects serum inflammation markers based on current studies.

Abstract. Backgrounds: Central obesity, as a pivotal component of metabolic syndrome is associated with numerous co-morbidities. Dietary factors influence central obesity by increased inflammatory status. However, recent studies didn’t evaluate the association between central obesity and dietary inflammation index (DII®) that give score to dietary factors according to their inflammatory potential. In the current systematic review and meta-analysis, we summarized the studies that investigated the association between DII® with central obesity indices in the general populations. Methods: In a systematic search from PubMed, SCOPUS, Web of Sciences and Cochrane electronic databases, we collected relevant studies written in English and published until 30 October 2019. The population of included studies were apparently healthy subjects or individuals with obesity or obesity-related diseases. Observational studies that evaluated the association between DII® and indices of central obesity including WC or WHR were included. Results: Totally thirty-two studies were included; thirty studies were cross-sectional and two were cohort studies with 103071 participants. Meta-analysis of observational studies showed that higher DII® scores were associated with 1.81 cm increase in WC (Pooled weighted mean difference (WMD) = 1.813; CI: 0.785–2.841; p = 0.001). Also, a non-significant increase in the odds of having higher WC (OR = 1.162; CI: 0.95–1.43; p = 0.154) in the highest DII category was also observed. In subgroup analysis, the continent, dietary assessment tool and gender were the heterogeneity sources. Conclusion: The findings proposed that adherence to diets with high DII® scores was associated with increased WC. Further studies with interventional designs are necessary to elucidate the causality inference between DII® and central obesity indices.
