Comparing 7-Day Versus 6-8-Day Penicillin Treatment Intervals Among Pregnant People With Syphilis of Late or Unknown Duration: No Difference Found in Incidence of Congenital Syphilis.

Background: Guidelines recommend that pregnant patients with syphilis of late/unknown duration be treated with benzathine penicillin G, dosed as 3 weekly intramuscular injections (BPGx3) given ideally at strict 7-day intervals. Given limited pharmacokinetic data, it is unknown whether more flexible BPG treatment intervals might be effective in preventing congenital syphilis (CS). Methods: We used California surveillance data to identify birthing parent/infant dyads wherein the pregnant parent had syphilis of late/unknown duration between January 1, 2016 - June 30, 2019. We divided the dyads into 3 groups based on prenatal treatment: (1) BPGx3 at strict 7-day intervals, (2) BPGx3 at 6-8 day intervals, and (3) no/inadequate treatment. We then compared CS incidence among infants in each group. Results: We analyzed 1,092 parent/infant dyads: 607 (55.6%) in the 7-day treatment group, 70 (6.4%) in the 6-8 day treatment group, and 415 (38.0%) in the no/inadequate treatment group. The incidence proportion of infants meeting CS criteria in each group was, respectively, 5.6%, 5.7%, and 36.9%. Compared with BPGx3 at 7-day intervals, the odds of CS were 1.0 [95% CI 0.4-3.0] in the 6-8 day group and 9.8 [95% CI 6.6-14.7] in the no/inadequate treatment group. Conclusions: Prenatal BPGx3 at 6-8 days was no more likely to lead to CS in infants than 7-days. These findings hint that 6-8-day intervals might be adequate to prevent CS among pregnant people with syphilis of late/unknown duration. Consequently, it is possible that CS evaluation beyond an RPR at delivery may be unnecessary in asymptomatic infants whose parents received BPGx3 at 6-8 days.

Sexually Transmitted Human Papillomavirus: Update in Epidemiology, Prevention, and Management.

This review presents the epidemiology, pathophysiology, prevention, and management of sexually transmitted human papillomavirus (HPV) and its associated diseases. HPV is the most common sexually transmitted infection worldwide. Prevalence varies regionally. Low-risk strains cause anogenital warts, which can be managed with patient- or provider-applied therapies. High-risk strains cause lower anogenital cancers. Primary and secondary prevention strategies include vaccination and screening for precancerous lesions, respectively. Management of abnormal screening results vary by test result, anatomic site, and individual cancer risk. Approaches include close rescreening, high-resolution visualization with biopsy, and-when biopsy-proven precancer is identified-removal or destruction of the lesion.

Second and Third Trimester Fetal Death in the Setting of COVID-19: A California 2020 Case Series.

Maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the second and third trimesters of pregnancy may impact fetal development via vertical transmission, complications of coronavirus disease 2019 (COVID-19), or placental injury. However, potential associations between prenatal SARS-CoV-2 infection and fetal loss are not well understood. This case series of thirteen second and third trimester fetal losses reported by local public health departments to California's state public health surveillance included maternal clinical and demographic characteristics as well as placental pathology, fetal autopsy reports, and coroner report. There was no evidence that maternal COVID-19 disease severity, placental injury, or SARS-CoV-2 vertical transmission contributed to pregnancy loss. However, this case series is a limited sample; more research is needed to identify factors of prenatal SARS-CoV-2 that may contribute to fetal death in the second and third trimesters.

Geospatial Social Determinants of Health Correlate with Disparities in Syphilis and Congenital Syphilis Cases in California.

Syphilis and congenital syphilis (CS) are increasing in California (CA). From 2015 through 2019, for example, CA cases of early syphilis among reproductive-age females (15−44) and CS each increased by >200%. Certain populations­including people experiencing homelessness, using drugs, and/or belonging to certain racial/ethnic groups­have been disproportionately impacted. We hypothesized that geospatial social determinants of health (SDH) contribute to such health inequities. To demonstrate this, we geospatially described syphilis in CA using the Healthy Places Index (HPI). The HPI is a composite index that assigns a score to each CA census tract based on eight socioeconomic characteristics associated with health (education, housing, transportation, neighborhood conditions, clean environment, and healthcare access as well as economic and social resources). We divided CA census tracts into four quartiles based on HPI scores (with the lowest quartile having the least healthy socioeconomic and environmental conditions), then used 2013−2020 CA sexually transmitted diseases surveillance data to compare overall syphilis (among adults and adolescents) and CS case counts, incidence rates (per 100,000 population or live births), and incidence rate ratios (IRRs) among these quartiles. From 2013 to 2020, across all stages of syphilis and CS, disease burden was greatest in the lowest HPI quartile and smallest in the highest quartile (8308 cases (representing 33.2% of all incidents) versus 3768 (15.1%) for primary and secondary (P&S) syphilis; 5724 (31.6%) versus 2936 (16.2%) for early non-primary non-secondary (NPNS) syphilis; 11,736 (41.9%) versus 3026 (10.8%) for late/unknown duration syphilis; and 849 (61.9%) versus 57 (4.2%) for CS; all with p < 0.001). Using the highest HPI quartile as a reference, the IRRs in the lowest quartile were 17 for CS, 4.5 for late/unknown duration syphilis, 2.6 for P&S syphilis, and 2.3 for early NPNS syphilis. We thus observed a direct relationship between less healthy conditions (per HPI) and syphilis/CS in California, supporting our hypothesis that SDH correlate with disparities in syphilis, especially CS. HPI could inform allocation of resources to: (1) support communities most in need of assistance in preventing syphilis/CS cases and (2) reduce health disparities.

Congenital syphilis prevention in the context of methamphetamine use and homelessness.

BACKGROUND AND OBJECTIVES: Congenital syphilis (CS) is increasing in the United States and is associated with intersecting social and structural determinants of health. This study aimed to delineate birthing parent characteristics associated with CS in an adjusted model. METHODS (N = 720): People diagnosed with syphilis during pregnancy from 2017 to 2018 who were interviewed and linked to infants in the California state surveillance system were included (herein, "birthing parents"). Sociodemographic and clinical CS risk factors informed a stepwise multivariable logistic regression model in which the outcome of interest was infants born with CS. CS prevention continuums delineated the proportion of pregnant people with syphilis who completed steps (e.g., prenatal care entry, syphilis testing, treatment) needed to prevent CS; the outcome was delivering an infant without CS. We stratified continuums by homelessness and methamphetamine use to explore differences in CS outcomes. RESULTS: Of 720 birthing parents, 245 (34%) delivered an infant with CS. Although CS was initially associated with homelessness (odds ratio [OR] = 2.5, 95% confidence interval [CI]: 1.6, 4.0) and methamphetamine use (OR = 2.1, 95% CI: 1.4, 3.1), the addition of prenatal care into a final adjusted model attenuated these associations to not significant. In CS prevention continuums, delivering an infant without CS was less likely for people who reported methamphetamine use (p < .001) and/or homelessness (p < .001). However, when examining only those who received prenatal care, statistical differences for these predictors no longer existed. In the final adjusted model the following were associated with CS: no prenatal care (OR = 16.7, 95% CI: 9.2, 30.3) or late prenatal care (OR = 2.9, 95% CI: 1.9, 4.2); early stage of syphilis (OR = 2.6, 95% CI: 1.8, 3.7); living in Central California (OR = 2.1, 95% CI: 1.1, 4.2). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: This is the first analysis to explore birthing parent characteristics associated with delivering an infant with CS in an adjusted model. We demonstrate that prenatal care, when accessed, can result in effective CS prevention among people who are unhoused and/or using methamphetamine equally well compared to counterparts without these risk factors.

Provider preferences for anal cancer prevention screening: Results of the International Anal Neoplasia Society survey.

OBJECTIVE: This study explores provider preferences regarding anal cancer screening indications, initiation age, tools, and referral threshold to high resolution anoscopy (HRA). METHODS: International Anal Neoplasia Society affiliates were invited to complete an online survey. Options for initiation age and tools were delineated by sub-groups. HRA referral thresholds separately queried recommendations by patient immune status. RESULTS: One hundred forty respondents participated. Although consensus was lacking with regard to specific screening initiation age, more respondents recommended younger initiation ages for men who have sex with men (MSM) living with HIV (LWH) compared with MSM not LWH (p < 0.01). "No age threshold" ranged 44-55% among sub-groups with lower genital tract disease. Cytology and digital anorectal exam (DARE) were the most frequently selected tools for all sub-groups (ranges 77-90% and 74-86%, respectively). HRA was recommended significantly more frequently for MSM LWH (58%) and patients with vulvar cancer (52%) compared to others (p < 0.01). "Any [test] abnormality" was more often selected as indication for HRA for immunocompromised (56%) and immunocompetent (46%) patients than a specific cytology test result (29%, 36% respectively). CONCLUSION: Cytology and DARE were preferred screening tools; screening initiation age and HRA referral threshold showed less consensus. Evidence-based guidelines are needed and may lead to more consistent screening practices.

Neurosyphilis Surveillance: Exploring the Use of Multiple Data Sources to Better Understand Morbidity in California.

ABSTRACT: Accurate reporting of neurosyphilis diagnoses is important to quantify and monitor severe outcomes associated with infection of Treponemal pallidum. This analysis compared the demographic distribution of neurosyphilis diagnoses in sexually transmitted disease surveillance data with administrative hospital data in the California Project Area from 2016 to 2018. Although neurosyphilis morbidity was similar, significant differences were noted by sex, age group, race/ethnicity, and region. Both sexually transmitted disease surveillance and administrative hospital data may be imperfect systems to understand the true morbidity of neurosyphilis.

Knowing What We Do Not Know: Analysis of an Online Consultation Service to Identify Provider Knowledge Gaps in Sexually Transmitted Disease Care.

The national Sexually Transmitted Diseases (STD) Clinical Consultation Network receives requests regarding complex STD cases. A total of 927 requests from Western states, 2017 to 2019, were analyzed for STD of inquiry and syphilis-specific subtopics. Syphilis requests accounted for most queries, and the number and proportion of syphilis-related requests increased significantly over time.

SARS-CoV-2-Associated Deaths Among Persons Aged <21 Years - United States, February 12-July 31, 2020.

Since February 12, 2020, approximately 6.5 million cases of SARS-CoV-2 infection, the cause of coronavirus disease 2019 (COVID-19), and 190,000 SARS-CoV-2-associated deaths have been reported in the United States (1,2). Symptoms associated with SARS-CoV-2 infection are milder in children compared with adults (3). Persons aged <21 years constitute 26% of the U.S. population (4), and this report describes characteristics of U.S. persons in that population who died in association with SARS-CoV-2 infection, as reported by public health jurisdictions. Among 121 SARS-CoV-2-associated deaths reported to CDC among persons aged <21 years in the United States during February 12-July 31, 2020, 63% occurred in males, 10% of decedents were aged <1 year, 20% were aged 1-9 years, 70% were aged 10-20 years, 45% were Hispanic persons, 29% were non-Hispanic Black (Black) persons, and 4% were non-Hispanic American Indian or Alaska Native (AI/AN) persons. Among these 121 decedents, 91 (75%) had an underlying medical condition,* 79 (65%) died after admission to a hospital, and 39 (32%) died at home or in the emergency department (ED).† These data show that nearly three quarters of SARS-CoV-2-associated deaths among infants, children, adolescents, and young adults have occurred in persons aged 10-20 years, with a disproportionate percentage among young adults aged 18-20 years and among Hispanics, Blacks, AI/ANs, and persons with underlying medical conditions. Careful monitoring of SARS-CoV-2 infections, deaths, and other severe outcomes among persons aged <21 years remains particularly important as schools reopen in the United States. Ongoing evaluation of effectiveness of prevention and control strategies will also be important to inform public health guidance for schools and parents and other caregivers.

Congenital Syphilis Prevention: Strategies, Evidence, and Future Directions.

BACKGROUND: Congenital syphilis (CS)-the preventable transmission of Treponema pallidum from infected mother to fetus-remains a significant problem worldwide. METHODS: From July through November 2017, 239 articles relevant to CS prevention were identified via keyword searches in PubMed and Google Scholar, ancestry searches, and expert recommendation. Articles were then assessed for (1) measurement of a specified CS or adverse pregnancy outcomes (APOs) and (2) geographic setting in high/upper middle income countries according to United Nations criteria. In total, 119 articles met inclusion criteria. These were then vetted for 1 of 3 arms of CS prevention, after which additional ancestral searches were conducted within each arm to arrive at the final collection of articles per CS prevention strategy-maternal prenatal treatment (n = 33), prenatal screening (n = 24), and public health interventions that support screening and treatment (n = 15). RESULTS: Of the 7 studies that evaluated treatment with benzathine penicillin G (BPG) use within the context of a modern health care system, all showed BPG to be highly effective in CS prevention; 3 additional studies demonstrated BPG effectiveness in preventing APOs. Ten studies revealed early disease detection through prenatal screening significantly reduces CS and APOs when paired with BPG. There was limited literature evaluating public health interventions, such as partner notification, surveillance, and prenatal screening laws. CONCLUSIONS: Congenital syphilis is a preventable disease, effectively avoided with appropriate prenatal screening and BPG therapy. Increasing syphilis rates among all adults, accompanied by gaps in the provision of prenatal care to women at high risk of infection, are major contributors to CS persistence.

Childhood sexual and physical abuse histories, PTSD, depression, and HIV risk outcomes in women injection drug users: a potential mediating pathway.

We explored links between childhood sexual abuse (CSA), childhood physical abuse (CPA), posttraumatic stress disorder (PTSD)/depression, and women injection drug users' (IDUs') risk in 113 women recruited from two syringe exchange sites. More than half (56%) reported CSA, 68% CPA, 23% likely were depressed-only, and 53% likely had PTSD/depression. CSA was associated with sexual (p = 0.003) and drug risk (p = 0.05); CPA was not. CSA was associated with PTSD/depression (p = 0.03); PTSD/depression was associated with sexual (p < 0.01) and drug (p < 0.03) risk. After PTSD/depression adjustment, CSA was no longer associated with sexual or drug risk. These results suggest that women IDUs' CSA-to-risk path is mediated by PTSD/depression.
