Introduction Total adverse childhood experiences (ACEs) are gaining prominence as a risk factor for preterm birth (PTB). The emerging literature examining this relationship reports inconsistent findings. The purpose of this systematic review was to summarize the available evidence exploring whether total ACEs predict PTB. Methods A total of 386 studies were returned from searches on PubMed, PsycINFO, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). Nine studies were selected for final analysis and synthesis based on reporting of total ACEs and preterm birth gestational weeks or standard definition of birth before 37 weeks' gestational age. A systematic review rather than meta-analysis was selected to present the findings given the clinical and methodological (e.g., sample studied, measurement tools) heterogeneity of the retrieved studies and pregnancy outcomes measured. Results The nine studies report on birth outcomes for 6,087 women from a range of sociodemographic and ethnic backgrounds. Despite a wide range of study designs, measurement tools, and timings of ACEs exposure across studies, seven of the nine included studies showed significant relationships between ACEs and PTB. Conclusion Systematic review of the literature suggests that total ACEs are associated with PTB and provides an overview on the known associations. However, to date only nine studies have assessed this link, and more studies are needed, to explore the associations between ACEs and PTB using appropriate and valid instruments and doing so among more diverse populations.

A retrospective cohort study of people living with human immunodeficiency virus in Ontario, Canada which found no association between previous syphilis and neurocognition. Background: About 40% to 60% of people living with human immunodeficiency virus (HIV) experience neurocognitive impairments, irrespective of antiretroviral status. We hypothesized that a history of syphilis or neurosyphilis would be associated with worse neurocognitive outcomes in this population. Methods: Among health care–engaged people living with HIV in Ontario older than 16 years enrolled in the OHTN Cohort Study, neurocognitive outcomes were as follows: (1) self-reported Medical Outcome Study–HIV Health Survey 4-item cognitive scale; (2) average T score summary scores based on objective neuropsychological testing of complex attention, speed of processing, and learning/memory; and (3) global deficit score dichotomized into impaired/unimpaired neurocognitive status. Syphilis history was determined by laboratory data or chart review. Univariable and multivariable generalized linear mixed models assessed the association between each of: syphilis, number of episodes of syphilis, and years since syphilis diagnosis with these neurocognitive outcomes controlling for age, sex, race, education, income, years of HIV, nadir and most recent CD4 count, most recent HIV viral load, substance use, depression, and number of prior neurocognitive tests. Results: Of 1288 eligible participants, 218 (16.9%) had a history of syphilis at baseline and an additional 53 were diagnosed during follow up for a total of 271 (21.0%) at the most recent visit. Of those with past infection at baseline, 179 (82.1%) had 1 and 39 (17.9%) had 2 or more episodes of syphilis. In longitudinal multivariable models, we observed no relationship between syphilis diagnosis or years since syphilis diagnosis and any of the neurocognitive outcomes. Conclusions: In this sample, prior syphilis was not associated with worse neurocognitive outcomes over time according to self-reported scales or objective neuropsychological testing.
