Notification rates for syphilis in women of reproductive age and congenital syphilis in Australia, 2011-2021: a retrospective cohort analysis of national notifications data.

OBJECTIVES: To estimate notification rates for infectious syphilis in women of reproductive age and congenital syphilis in Australia. STUDY DESIGN: Retrospective cohort study; analysis of national infectious syphilis and enhanced congenital syphilis surveillance data. SETTING, PARTICIPANTS: Women aged 15-44 years diagnosed with infectious syphilis, and babies with congenital syphilis, Australia, 2011-2021. MAIN OUTCOME MEASURES: Numbers and rates of infectious syphilis notifications, by Indigenous status and age group; numbers and rates of congenital syphilis, by Indigenous status of the infant; antenatal care history for mothers of infants born with congenital syphilis. RESULTS: During 2011-2021, 5011 cases of infectious syphilis in women aged 15-44 years were notified. The notification rate for Aboriginal and Torres Strait Islander women rose from 56 (95% confidence interval [CI], 45-65) cases per 100 000 in 2011 to 227 (95% CI, 206-248) cases per 100 000 population in 2021; for non-Indigenous women, it rose from 1.1 (95% CI, 0.8-1.4) to 9.2 (95% CI, 8.4-10.1) cases per 100 000 population. The notification rate was higher for Aboriginal and Torres Strait Islander women than for non-Indigenous women (incidence rate ratio [IRR], 23.1; 95% CI, 19.7-27.1), lower for 15-24- (IRR, 0.7; 95% CI, 0.6-0.9) and 35-44-year-old women (IRR, 0.6; 95% CI, 0.5-0.7) than for 25-34-year-old women, and higher in remote regions than in major cities (IRR, 2.7; 95% CI, 2.2-3.8). During 2011-2021, 74 cases of congenital syphilis were notified, the annual number increasing from six in 2011 to a peak of 17 in 2020; the rate was consistently higher among Aboriginal and Torres Strait Islander infants than among non-Indigenous infants (2021: 38.3 v 2.1 per 100 000 live births). The mothers of 32 infants with congenital syphilis (43%) had not received antenatal care. CONCLUSIONS: The number of infectious syphilis notifications for women of reproductive age increased in Australia during 2011-2021, as did the number of cases of congenital syphilis. To avert congenital syphilis, antenatal screening of pregnant women, followed by prompt treatment for infectious syphilis when diagnosed, needs to be improved.

Care of the Postpartum Patient in the Emergency Department: A Systematic Review with Implications for Maternal Mortality.

OBJECTIVE: Approximately one-third of maternal deaths occur postpartum. Little is known about the intersection between the postpartum period, emergency department (ED) use, and opportunities to reduce maternal mortality. The primary objectives of this systematic review are to explore the incidence of postpartum ED use, identify postpartum disease states that are evaluated in the ED, and summarize postpartum ED use by race/ethnicity and payor source. STUDY DESIGN: We searched PubMed, Embase, Cumulative Index of Nursing and Allied Health Literature (CINAHL), ClinicalTrials.gov, Cochrane CENTRAL, Social Services Abstracts, and Scopus from inception to September 19, 2019. Each identified abstract was screened by two authors; the full-text manuscripts of all studies deemed to be potential candidates were then reviewed by the same two authors and included if they were full-text, peer-reviewed articles in the English language with primary patient data reporting care of a female in the ED in the postpartum period, defined as up to 1 year after the end of pregnancy. RESULTS: A total of 620 were screened, 354 records were excluded and 266 full-text articles were reviewed. Of the 266 full-text articles, 178 were included in the systematic review; of these, 108 were case reports. Incidence of ED use by postpartum females varied from 4.8 to 12.2% in the general population. Infection was the most common reason for postpartum ED evaluation. Young females of minority race and those with public insurance were more likely than whites and those with private insurance to use the ED. CONCLUSION: As many as 12% of postpartum women seek care in the ED. Young minority women of lower socioeconomic status are more likely to use the ED. Since approximately one-third of maternal deaths occur in the postpartum period, successful efforts to reduce maternal mortality must include ED stakeholders. This study is registered with the Systematic Review Registration (identifier: CRD42020151126). KEY POINTS: · Up to 12% of postpartum women seek care in the ED.. · One-third of maternal deaths occur postpartum.. · Maternal mortality reduction efforts should include ED stakeholders..

PCSK9 loss-of-function variants and risk of infection and sepsis in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort.

BACKGROUND: Elevated proprotein convertase subtilisin/kexin type 9 (PCSK9) levels have been associated with adverse outcomes in patients hospitalized for sepsis. PCSK9 loss-of-function (LOF) variants area associated with lower low-density lipoprotein cholesterol (LDL-C) levels. Decreased LDL-C is a biomarker of acute and chronic infection and sepsis risk. We examined the association between presence of two genetic PCSK9 LOF variants and risk of infection and sepsis in community-dwelling adults. METHODS: We analyzed data from 10,924 Black participants tested for PCSK9 LOF variants in the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort. The primary endpoint was hospitalization for a serious infection. Within serious infection hospitalizations, we defined sepsis as ≥2 system inflammatory response syndrome criteria. Using multivariable Cox and logistic regression, we investigated the association between LOF variants and hospitalization for infection and sepsis events, adjusting for sociodemographics, health behaviors, chronic medical conditions and select biomarkers. RESULTS: Among 10,924 Black participants, PCSK9 LOF variants were present in 244 (2.2%). Serious infection hospitalizations occurred in 779 participants (14 with PCSK9 variants and 765 without). The presence of PCSK9 variants was not associated with infection risk (adjusted HR 0.68; 95% CI: 0.38-1.25). Among participants hospitalized for a serious infection, the presence of PCSK9 variants was not associated with sepsis (adjusted OR 7.31; 95% CI = 0.91-58.7). CONCLUSIONS: PCSK9 LOF variants are not associated with increased risk of hospitalization for a serious infection. Among those hospitalized for a serious infection, PCSK9 LOF variants was not associated with odds of sepsis.
