Association Between Childhood Adversity and Functional Outcomes in People With Psychosis: A Meta-analysis.

BACKGROUND AND HYPOTHESIS: Despite the accepted link between childhood adversity (CA) and psychotic disorders, evidence on the relationship between CA and poor functional outcome remains less consistent and has never been reviewed quantitatively. The aim of this meta-analysis was to systematically examine the association between CA and functional outcomes in people with psychotic disorders. STUDY DESIGN: The study protocol was registered on the International Prospective Register of Systematic Reviews (CRD42021254201). A search was conducted across EMBASE, MEDLINE, PsycINFO, and Cochrane Libraries (CENTRAL) using search terms related to psychosis; CA (general, sexual abuse, physical abuse, emotional abuse, physical neglect, and emotional neglect); and functional outcomes (social, occupational, and general functioning [GF]). We conducted random-effects models, sensitivity and heterogeneity analyses, meta-regressions, and we assessed quality. STUDY RESULTS: Our meta-analysis comprised 35 studies, including 10 568 cases with psychosis. General CA was negatively associated with GF (28 studies; r = -0.109, 95%CI = -0.161 to -0.05, P < .001), with greater effects in prospective data (10 studies; r = -0.151, 95% CI = -0.236 to -0.063, P = .001). General CA was also associated with social functioning (r = -0.062, 95% CI = -0.120 to -0.004, P = .018) but not occupational outcomes. All CA subtypes except sexual abuse were significantly associated with GF, with emotional and physical neglect showing the largest magnitudes of effect (ranging from r = -0.199 to r = -0.250). CONCLUSIONS: This meta-analysis provides evidence for a negative association between general CA, specific subtypes, and general and social functional outcomes in people with psychosis.

High-resolution within-sewer SARS-CoV-2 surveillance facilitates informed intervention.

To assist in the COVID-19 public health guidance on a college campus, daily composite wastewater samples were withdrawn at 20 manhole locations across the University of Colorado Boulder campus. Low-cost autosamplers were fabricated in-house to enable an economical approach to this distributed study. These sample stations operated from August 25th until November 23rd during the fall 2020 semester, with 1512 samples collected. The concentration of SARS-CoV-2 in each sample was quantified through two comparative reverse transcription quantitative polymerase chain reactions (RT-qPCRs). These methods were distinct in the utilization of technical replicates and normalization to an endogenous control. (1) Higher temporal resolution compensates for supply chain or other constraints that prevent technical or biological replicates. (2) The data normalized by an endogenous control agreed with the raw concentration data, minimizing the utility of normalization. The raw wastewater concentration values reflected SARS-CoV-2 prevalence on campus as detected by clinical services. Overall, combining the low-cost composite sampler with a method that quantifies the SARS-CoV-2 signal within six hours enabled actionable and time-responsive data delivered to key stakeholders. With daily reporting of the findings, wastewater surveillance assisted in decision making during critical phases of the pandemic on campus, from detecting individual cases within populations ranging from 109 to 2048 individuals to monitoring the success of on-campus interventions.

Effects of stroke on informal carers.

Informal carers have a pivotal role in caring for patients who have had a stroke. Research has shown that informal carers have unmet information, psychological and social needs. There is a lack of research about how informal carers in Northern Ireland manage the role of caring for a patient who has experienced stroke, and what kind of support they need and receive. This literature review explores the experiences of informal carers providing stroke care in the home. The issues highlighted in the article are relevant worldwide, because the incidence of stroke is increasing in developed and developing countries.
