Bartonella Seroreactivity Among Persons Experiencing Homelessness During an Outbreak of Bartonella quintana in Denver, Colorado, 2020.

ABSTRACT: During a recent outbreak of Bartonella quintana disease in Denver, 15% of 241 persons experiencing homelessness who presented for severe acute respiratory syndrome coronavirus 2 testing were seroreactive for Bartonella. Improved recognition of B quintana disease and prevention of louse infestation are critical for this vulnerable population.

Project description:ImportanceShort interpregnancy intervals (SIPIs) are associated with increased risk of adverse maternal and neonatal outcomes. Disparities exist across socioeconomic status, but there is little information on SIPIs among women experiencing homelessness.ObjectiveTo investigate (1) differences in rates and characteristics of SIPIs between women experiencing homelessness and domiciled women, (2) whether the association of homelessness with SIPIs differs across races and ethnicities, and (3) whether the association between SIPIs of less than 6 months (very short interpregnancy interval [VSIPIs]) and maternal and neonatal outcomes differs between participant groups.Design, setting, and participantsThis cohort study used a Colorado statewide database linking the Colorado All Payer Claims Database, Homeless Management Information System, death records, and infant birth records. Participants included all women who gave birth between January 1, 2016, and December 31, 2021. Data were analyzed from September 1, 2022, to May 10, 2023.ExposuresHomelessness and race and ethnicity.Main outcomes and measuresThe primary outcome consisted of SIPI, a binary variable indicating whether the interval between delivery and conception of the subsequent pregnancy was shorter than 18 months. The association of VSIPI with maternal and neonatal outcomes was also tested.ResultsA total of 77 494 women (mean [SD] age, 30.7 [5.3] years) were included in the analyses, of whom 636 (0.8%) were women experiencing homelessness. The mean (SD) age was 29.5 (5.4) years for women experiencing homelessness and 30.7 (5.3) years for domiciled women. In terms of race and ethnicity, 39.3% were Hispanic, 7.3% were non-Hispanic Black, and 48.4% were non-Hispanic White. Associations between homelessness and higher odds of SIPI (adjusted odds ratio [AOR], 1.23 [95% CI, 1.04-1.46]) were found. Smaller associations between homelessness and SIPI were found among non-Hispanic Black (AOR, 0.59 [95% CI, 0.37-0.96]) and non-Hispanic White (AOR, 0.57 [95% CI, 0.39-0.84]) women compared with Hispanic women. A greater association of VSIPI with emergency department visits and low birth weight was found among women experiencing homelessness compared with domiciled women, although no significant differences were detected.Conclusions and relevanceIn this cohort study of women who gave birth from 2016 to 2021, an association between homelessness and higher odds of SIPIs was found. These findings highlight the importance of conception management among women experiencing homelessness. Racial and ethnic disparities should be considered when designing interventions.

Project description:IntroductionGiven the increasing rates of homelessness in recent years, there is an urgent need to address the ongoing discrimination and societal disinterest in preventing, reducing and ending homelessness. There is no systematic review of experiences of stigma and discrimination among persons experiencing homelessness or interventions to combat this discrimination. The objective for the proposed study is to identify ways in which persons experiencing homelessness have been stigmatised and discriminated against, the results of these experiences, and interventions to reduce stigma and discrimination towards persons experiencing homelessness.Methods and analysisWe are conducting a scoping review with guidance from the JBI Manual for Evidence Synthesis and Arksey and O'Malley's framework. From 15 to 19 July 2022, we searched the following databases from our institutional licensed years of coverage: Medline, Embase, CINAHL Complete, Academic Search Ultimate, APA PsycINFO, Science Citation Index Expanded, Social Sciences Citation Index, Arts & Humanities Citation Index, Emerging Sources Citation Index, Left, PAIS International, PILOTS, Psychology & Behavioral Sciences Collection, Sociological Abstracts, and Dissertations and Theses Global. Two independent reviewers are screening study titles/abstracts and will independently screen the full texts. Study inclusion criteria include any study type reporting primary findings of English-language research on non-refugee persons experiencing homelessness in any type of setting or service worldwide. Three reviewers will then chart data of our included studies. Data will be extracted and organised into categories and subthemes in tabular form. To understand the validity of the scoping review findings in the local context and to gather additional perspectives on the topic, we will conduct an 'expert consultation' workshop.Ethics and disseminationThis study has ethics approval from the University of Utah Institutional Review Board. Review findings will be disseminated through a peer-reviewed journal and at conferences. We plan to preregister this protocol with Open Science Framework.
