Abstract
Background Congenital syphilis (CS) is associated with significant perinatal morbidity and mortality. The study objectives were to compare risk factors among women with syphilis infection whose pregnancies did and did not result in CS cases and to evaluate other geographic and socioeconomic characteristics of county of residence as a measure of healthcare inequity. Methods This study linked maternal and congenital syphilis data from the Georgia Department of Public Health (DPH), 2008-2015. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline was followed. Demographic, behavioral, and case characteristics were compared among women with syphilis infection who did and did not have an infant with CS. Chi-square, Fisher's exact, and multivariate regression analyses were performed using STATA 14.2 (College Station, TX). Results Of 505 women with syphilis infection, 23% had an infant with CS, while 77% did not. After adjusting for race/ethnicity, factors associated with CS outcome were age greater than 35 years (adjusted odds ratio (aOR) 3.88; 95% confidence interval (CI) 1.01-14.89), hospital/emergency department diagnosis of syphilis (aOR 3.43; 95% CI 1.54-7.62), and high-risk behaviors such as exchanging sex for money or drugs (aOR 3.25; 95% CI 1.18-8.98). There were no associations between characteristics of county of residence and CS outcome. Conclusions This study highlights risk factors that may be associated with CS incidence and the adverse pregnancy outcomes associated with CS. Further work is needed to study improved data collection systems, contributing factors related to CS as well as prevention measures in the United States.

Abstract
BACKGROUND The persistence of congenital syphilis (CS) remains an important concern in the United States. We use the 2018 data to refine a previous predictive model that identifies US counties at elevated risk for CS in 2018. METHODS Using county-level socioeconomic and health-related data from various sources, we developed a logistic regression predictive model to identify county-level factors associated with a county having had 1 or more CS case reported to the National Notifiable Diseases Surveillance System in 2018. We developed a risk scoring algorithm, identified the optimal risk score cutpoint to identify counties at elevated risk, and calculated the live birth to CS case ratio for counties by predicted risk level to compare counties at elevated risk with counties not at elevated risk. RESULTS We identified several county-level factors associated with a county having 1 or more CS case in 2018 (area under the curve, 88.6%; Bayesian information criterion, 1551.1). Using a risk score cutoff of 8 or higher (sensitivity, 83.2%; specificity, 79.4%), this model captured 94.7% (n = 1,253) of CS cases born in 2018 and identified 850 (27%) counties as being at elevated risk for CS. The live birth to CS case ratio was lower in counties identified as at elevated risk (2,482) compared with counties categorized as not at elevated risk (10,621). CONCLUSIONS Identifying which counties are at highest risk for CS can help target prevention efforts and interventions. The relatively low live birth to CS case ratio in elevated risk counties suggests that implementing routine 28-week screening among pregnant women in these counties may be an efficient way to target CS prevention efforts.

Abstract
ABSTRACT We reviewed all cases of syphilis reported among pregnant women in Florida in 2018 for syphilitic reinfection. Nineteen (7.3%) of 261 pregnant women with syphilis were reported as reinfected during the same pregnancy. Timely rescreening and treatment prevented 6 (31.6%) of 19 reinfected women from delivering infants with congenital syphilis.

Abstract
BACKGROUND The Centers for Disease Control and Prevention (CDC) recommends that all women with a stillbirth have a syphilis test after delivery. Our study seeks to evaluate adherence to CDC guidelines for syphilis screening among women with a stillbirth delivery. METHODS We used data recorded in electronic health records for women who gave birth between January 1, 2014, and December 31, 2016. Patients were included if they were 18 to 44 years old and possessed an International Classification of Diseases, Ninth Revision or Tenth Revision, Clinical Modification diagnosis of stillbirth. Stillbirth diagnoses were confirmed through a random sample of medical chart reviews. To evaluate syphilis screening, we estimated the proportion of women who received syphilis testing within 300 days before stillbirth, women who received syphilis testing within 30 days after a stillbirth delivery, and women who received syphilis testing both before and after stillbirth delivery. RESULTS We identified 1111 stillbirths among a population of 865,429 unique women with encounter data available from electronic health records. Among a sample of 127 chart-reviewed cases, only 35 (27.6%) were confirmed stillbirth cases, 45 (35.4%) possible stillbirth cases, 39 (30.7%) cases of miscarriage, and 8 (6.3%) cases of live births. Among confirmed stillbirth cases, 51.4% had any syphilis testing conducted, 31.4% had testing before their stillbirth delivery, 42.9% had testing after the delivery, and only 22.9% had testing before and after delivery. CONCLUSIONS A majority of women with a stillbirth delivery do not receive syphilis screening adherent to CDC guidelines. Stillbirth International Classification of Diseases codes do not accurately identify cases of stillbirth.

Abstract
OBJECTIVES Congenital syphilis (CS) is the result of antepartum transmission from mother to fetus of the spirochete Treponema pallidum. Although preventable through timely screening and treatment, the incidence of CS in the United States is increasing. This review describes the epidemiological trends in CS in the United States from 1980 to 2019 and characteristics of mothers of infants with CS. METHODS We performed a narrative review of epidemiological studies of CS following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for reporting of observational studies in epidemiology. Quality and bias of included studies were assessed using the Newcastle-Ottawa Scale. Studies that described the demographics and characteristics of pregnant women with syphilis or who delivered an infant with CS in the United States were identified from PubMed and Embase. RESULTS We identified a total of 2771 studies, of which 309 were selected for further review and 27 were included in the final analysis. Substance use during pregnancy was a risk factor for CS in 16 studies. Maternal cocaine use was described in 11 of the 16 studies, 10 of which were published between the years 1980 and 1999. No prenatal care was a risk factor for CS in 17 studies. Evidence of inadequate syphilis testing (i.e., no maternal screen, first screen after the first trimester, or no repeat screen in third trimester) or treatment (i.e., no treatment, treatment <30 days before delivery, or nonpenicillin treatment) was significantly associated with CS in 13 studies. Finally, higher rates of CS were reported among African American women in 11 studies. CONCLUSIONS Infection with and antepartum transmission of syphilis disproportionately affect certain subgroups of women. Women who report substance use during pregnancy are more likely to give birth to an infant with CS. No prenatal care and evidence of inadequate syphilis testing and treatment during pregnancy are also significantly associated with giving birth to an infant with CS. Finally, cases of CS disproportionately affect African American women. Addressing the CS epidemic will require identification and targeted allocation of resources to communities at elevated risk for syphilis, removal of barriers to prenatal care, and ensuring timely treatment and adequate partner notification of identified cases.

Abstract
Guidelines can help healthcare practitioners manage syphilis in pregnancy and prevent perinatal death or disability. We conducted systematic reviews to locate guidance documents describing management of syphilis in pregnancy, 2003–2017. We compared country and regional guidelines with current World Health Organization (WHO) guidelines. We found 64 guidelines with recommendations on management of syphilis in pregnancy representing 128 of the 195 WHO member countries, including the two WHO guidelines published in 2016 and 2017. Of the 62 guidelines, 16 were for countries in Africa, 21 for the Americas, two for Eastern Mediterranean, six for Europe and 17 for Asia or the Pacific. Fifty-seven (92%) guidelines recommended universal syphilis screening in pregnancy, of which 46 (81%) recommended testing at the first antenatal care visit. Also, 46 (81%) recommended repeat testing including 21 guidelines recommended this during the third pregnancy trimester and/or at delivery. Fifty-nine (95%) guidelines recommended benzathine penicillin G (BPG) as the first-line therapy for syphilis in pregnancy, consistent with WHO guidelines. Alternative regimens to BPG were listed in 42 (68%) guidelines, primarily from Africa and Asia; only 20 specified that non-penicillin regimens are not proven-effective in treating the fetus. We identified guidance recommending use of injectable penicillin in exposed infants for 112 countries. Most guidelines recommended universal syphilis testing for pregnant women, repeat testing for high-risk women and treatment of infected women with BPG; but several did not. Updating guidance on syphilis testing and treatment in pregnancy to reflect global norms could prevent congenital syphilis and save newborn lives.

Abstract
OBJECTIVE To describe recent syphilis trends among pregnant women and to evaluate the prevalence of reported high-risk behaviors in this population. METHODS We analyzed U.S. national case report data for 2012-2016 to assess trends among pregnant women with all stages of syphilis. Risk behavior data collected through case interviews during routine local health department investigation of syphilis cases were used to evaluate the number of pregnant women with syphilis reporting these behaviors. RESULTS During 2012-2016, the number of syphilis cases among pregnant women increased 61%, from 1,561 to 2,508, and this increase was observed across all races and ethnicities, all women aged 15-45 years, and all U.S. regions. Of 15 queried risk factors, including high-risk sexual behaviors and drug use, 49% of pregnant women with syphilis did not report any in the past year. The most commonly reported risk behaviors were a history of a sexually transmitted disease (43%) and more than one sex partner in the past year (30%). CONCLUSION Syphilis cases among pregnant women increased from 2012 to 2016, and in half, no traditional behavioral risk factors were reported. Efforts to reduce syphilis among pregnant women should involve increasing health care provider awareness of the Centers for Disease Control and Prevention and the American College of Obstetricians and Gynecologists' recommendations, which include screening all pregnant women for syphilis at the first prenatal visit and rescreening high-risk women during the third trimester and at delivery. Health care providers should also consider local syphilis prevalence in addition to individual reported risk factors when deciding whether to repeat screening.

Abstract
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.

Abstract
BACKGROUND Congenital syphilis occurs when a pregnant woman with syphilis is not diagnosed or treated and the infection is passed in utero, causing severe infant morbidity and mortality. Congenital syphilis is easily prevented if women receive timely and adequate prenatal care. Cases of congenital syphilis are considered indicators of problems in the safety net. However, maternal social and behavioral factors can impede women's care, even when providers follow guidelines. METHODS We reviewed case interviews and maternal records for 23 congenital syphilis cases reported to the Centers for Disease Control and Prevention from Indiana between 2014 and 2016. We used qualitative methods to analyze narrative notes from maternal interviews to learn more about factors that potentially contributed to congenital syphilis cases. RESULTS All providers followed Centers for Disease Control and Prevention and state recommendations for screening and treatment for pregnant women with syphilis. Twenty-one of 23 women had health insurance. The number of prenatal care visits women had was suboptimal; more than one third of women had no prenatal care. Nearly one third of women's only risk factor was sex with a primary male sex partner. The majority of women suffered social vulnerabilities, including homelessness, substance abuse, and incarceration. CONCLUSIONS Despite provider adherence to guidelines and health insurance availability, some pregnant women with syphilis are unlikely to receive timely diagnosis and treatment. Pregnant women at high risk for syphilis may need additional social and material support to prevent a congenital syphilis case. Additional efforts are needed to reach the male partners of vulnerable females with syphilis.

Abstract
BACKGROUND Louisiana has had the highest rates of congenital syphilis (CS) in the nation since 2012. Congenital syphilis case review boards were established statewide in 2016 to study CS cases and identify interventions. METHODS We summarized the findings of CS review boards, assessed which cases were preventable by prenatal care providers, reviewed recommended interventions, and assessed subsequent improvement in provider practices. RESULTS All 79 CS cases reported from January 2016 to July 2017 were reviewed by boards during August 2016 to August 2017. Twenty-six (33%) cases that could have been prevented by prenatal care providers had: lack of rescreening at 28 to 32 weeks (n = 15), lack of any screening (n = 5), treatment delay (n = 4), or incorrect interpretation of test results (n = 2). Twenty-one (27%) cases were possibly preventable by providers including: mother did not return for follow-up and treatment (n = 19), late third trimester reactive test with premature delivery (n = 1), or incomplete treatment and lack of follow-up by health department staff (n = 1). Thirty-two (40%) cases that were unlikely to be prevented by providers had: nonreactive test at 28-32 weeks then reactive test <30 days before delivery (n = 10), no prenatal care (n = 9), mother adequately treated, case by infant criteria (n = 8), first/second trimester nonreactive, reactive at preterm delivery (n = 4), or mother adequately treated, reinfected before delivery (n = 1). Providers were advised to adhere to CDC recommended syphilis screening and treatment protocols and rapidly report pregnant women with syphilis. Many providers changed their procedures. CONCLUSIONS Congenital syphilis case review boards identified practices with inadequate screening, treatment, or reporting. Sharing these findings with providers changed practices and may prevent future cases.

Abstract
BACKGROUND Congenital syphilis can be prevented if syphilis is treated early in pregnancy. Identifying women with syphilis who are pregnant facilitates prioritization for follow-up. In 2016, Florida reported 1062 female syphilis cases, aged 15 to 44 years, and 160 (15%) cases were missing pregnancy status. The Florida Department of Health developed a system-generated weekly email notification sent to local program staff for all female syphilis investigations with unknown pregnancy status. We describe the outcome of these efforts to reduce unknown pregnancy status among women with syphilis. METHODS Review of the frequency and outcomes (reduction in investigations flagged and change in pregnancy status variable) of the first email notification (October 2, 2017) were compared with subsequent notifications through June 25, 2018. In addition, we reviewed pregnancy status of reported female syphilis cases (age, 15-44 years) from 2013 to 2018. RESULTS The first email notification listed 76 investigations with unknown pregnancy status. This number decreased to 40 in 1 week and to 22 by 1 month. The decreased volume continued through June 2018 (n = 13). Of the original 76 investigations, 3 women were pregnant, and 38 (50%) were determined to meet the syphilis case definition (including 1 who was pregnant). In 2017, pregnancy ascertainment for female syphilis cases reached 98%. CONCLUSIONS Focused efforts using email notification to obtain pregnancy status improved ascertainment in large sexually transmitted disease (STD) programs with minimal effort. Most but not all women with unknown pregnancy status were identified as not pregnant.

Abstract
BACKGROUND The success of an intervention to prevent syphilis will depend on the context and the goal of the intervention. To help programs choose interventions, we reviewed major changes in context and types of interventions that may be effective. METHODS We reviewed the literature on the changing context of syphilis in the United States and interventions to prevent syphilis, focusing on articles that included evidence of effectiveness. RESULTS Populations acquiring syphilis are constantly changing. Currently, incidence is very high among men who have sex with men (MSM). Among adults, late disease caused by syphilis has become rare. Congenital syphilis incidence has been low but is increasing, and morbidity and mortality remain high when babies are infected. Congenital syphilis now causes more deaths than syphilis among adults.Routine screening of MSM can identify and treat infections before they progress to disease (secondary prevention). Screening rates are highest when done as part of routine standing orders. Partner notification effectiveness has decreased, partly because many partners are anonymous. Most congenital syphilis can be prevented by screening pregnant women; it has been eliminated in areas where intense primary prevention efforts eliminated syphilis among women. CONCLUSIONS So far, no program has stopped the increasing rates of infection among MSM, but secondary prevention efforts have prevented most disability. Congenital syphilis is increasing, and can be decreased by screening pregnant women and stopped by intensive efforts to prevent infection among women.

Abstract
BACKGROUND From 2012 to 2014, rates of congenital syphilis increased in Louisiana and Florida. We evaluated the effectiveness of early (first or second) and third trimester syphilis screening for the prevention of congenital syphilis in these high-morbidity states. METHODS Reported syphilis cases among pregnant women in Louisiana and Florida during January 1, 2013, to December 31, 2014, were reviewed for documented screening for syphilis in the first 2 trimesters and third trimester. Pregnant women with syphilis were linked to congenital syphilis records and stratified by whether the pregnancy led to a reported congenital syphilis case. RESULTS Seven hundred ten pregnant women with syphilis in Louisiana and Florida were linked to 155 congenital syphilis cases. Three hundred seventy (52%) pregnant women with syphilis were staged as early syphilis (n = 270) or high-titer late or unknown duration-latent syphilis (n = 100), and 109 (70% of the total) were linked to congenital syphilis cases. Screening in the first 2 trimesters identified 513 pregnant women who tested positive for syphilis, and 470 (92%) potential congenital syphilis were averted. One hundred nine pregnant women tested positive for syphilis in the third trimester, and 85 (78%) had babies without congenital syphilis. During their pregnancy, 85 (12%) women tested negative at least once, and 55 (65%) had babies with congenital syphilis. Thirty-nine women had no reported syphilis screening 30 days or longer before delivery. CONCLUSIONS Screening for syphilis both early and in the third trimester prevented many pregnant women with syphilis from having a baby with congenital syphilis. Preventing all congenital syphilis would likely require preventing all syphilis among women.

Abstract
This study aimed to estimate the prevalence of syphilis and HIV infection during pregnancy, the mother to child transmission of syphilis and the incidence of congenital syphilis in incarcerated women in Brazil; to compare these rates to those observed in pregnant women outside of jail; and to verify the maternal factors associated with syphilis infection during pregnancy in free and incarcerated women. We used data from two nationwide studies conducted during the period 2011-2014. The Birth in Brazil study included 23,894 free women cared for in 266 hospitals. The Maternal and Infant Health in Prisons study included 495 incarcerated pregnant women or mothers living with their children, according to a census conducted in 33 female prisons. The same case definitions and data collection methods were used in both studies. The chi-square test was used to compare the characteristics of incarcerated and free women with a significance of 0.05. For incarcerated women, the estimated prevalence of syphilis during pregnancy was 8.7% (95%CI: 5.7-13.1) and for HIV infection 3.3% (95%CI: 1.7-6.6); the estimated mother to child transmission of syphilis was 66.7% (95%CI: 44.7-83.2) and the incidence of congenital syphilis was 58.1 per 1,000 living newborns (95%CI: 40.4-82.8). Incarcerated women had a greater prevalence of syphilis and HIV infection during pregnancy, lower quality of antenatal care and higher levels of social vulnerability. Syphilis infection showed to be an indicator of social vulnerability in free women, but not in incarcerated women. Health initiatives in prison are necessary to reduce healthcare inequalities and should include adequate antenatal and birth care.

Abstract
OBJECTIVES In 2009, due to increasing congenital syphilis rates, prenatal syphilis tests (PST) at both mid-gestation and delivery were added to first trimester prenatal screening in the province of Alberta. We sought to determine the proportion of mothers who had all three recommended PSTs during this period and to identify factors associated with incomplete PST. METHODS A cohort of all pregnancies resulting in a live or stillborn infant in Alberta for 2010 and 2011 was developed from Vital Statistics and linked with prenatal screening data to determine the number and timing of PSTs for pregnant women. The proportion of women who had PSTs at the three recommended time points in pregnancy and associated correlates were identified using basic statistics and logistic regressions. RESULTS Of 99,609 pregnancies, 20.7% had all three PSTs at the recommended time points. Overall, 98.5% (98,162) had at least one PST, 1.5% only had PST at delivery and 1.5% had no PST performed. Independent risk factors for not having the three recommended PSTs included First Nations status (adjusted odds ratio [AOR]: 1.78 [95% CI: 1.62-1.96]), rural remote residence (AOR 3.61 [95% CI: 3.10-4.20]) and sole use of a midwife for prenatal care (AOR 13.70 [95% CI: 9.20-20.39]). CONCLUSIONS Nearly all pregnant women in Alberta received a PST at least once during their pregnancy, however far fewer received PSTs at the recommended time points. Interventions that target those who are less likely to be prenatally screened may help to ensure that pregnant women get early and appropriate care for syphilis during pregnancy.

Abstract
In industrialized countries, the incidence of syphilis has decreased dramatically since the discovery of penicillin in the 1940s. However, syphilis and congenital syphilis are far from eradicated, especially in low- and middle-income countries. Syphilis in pregnant women is a cause of adverse pregnancy outcomes that can be prevented by screening for syphilis and early treatment in pregnancy. Several studies have found screening of pregnant women for syphilis to be a highly cost-effective intervention, even if the prevalence of syphilis is low. Obstacles to universal screening of pregnant women include low awareness of syphilis and low quality of antenatal care and healthcare in general in many low- and middle-income countries. For these settings, we need simpler and more reliable serological tests for syphilis, but we also need to strengthen health services in general to ensure sustainable antenatal care services to ensure sustainability of syphilis screening programmes.

Congenital syphilis: trends in mortality and morbidity in the United States, 1999 through 2013. Am J Obstet Gynecol 2016; 214:381.e1-9.

Abstract
BACKGROUND Congenital syphilis (CS) results when an infected pregnant mother transmits syphilis to her unborn child prior to or at delivery. The severity of infection can range from a delivery at term without signs of infection to stillbirth or death after delivery. OBJECTIVE We sought to describe CS morbidity and mortality during 1999 through 2013. STUDY DESIGN National CS case data reported to Centers for Disease Control and Prevention during 1999 through 2013 were analyzed. Cases were classified as dead (stillbirths and deaths up to 12 months after delivery), morbid (cases with strong [physical, radiographic, and/or nonserologic laboratory] evidence of CS), and nonmorbid (cases with a normal physical examination reported, without strong evidence of infection). Annual rates of these cases were calculated. Cases were compared using selected maternal and infant criteria. RESULTS During 1999 through 2013, 6383 cases of CS were reported: 6.5% dead, 33.6% morbid, 53.9% nonmorbid, and 5.9% unknown morbidity; 81.8% of dead cases were stillbirths. Rates of dead, morbid, and nonmorbid cases all decreased over this time period, but the overall proportions that were dead or morbid cases did not significantly change. The overall case fatality ratio during 1999 through 2013 was 6.5%. Among cases of CS, maternal race/ethnicity was not associated with increased morbidity or death, although most cases (83%) occurred among black or Hispanic mothers. No or inadequate treatment for maternal syphilis, <10 prenatal visits, and maternal nontreponemal titer ≥1:8 increased the likelihood of a dead case; risk of a dead case increased with maternal nontreponemal titer (χ(2) for trend P < .001). Infants with CS born alive at <28 weeks' gestation (relative risk, 107.4; P < .001) or born weighing <1500 g (relative risk, 43.9; P < .001) were at greatly increased risk of death. CONCLUSION CS remains an important preventable cause of perinatal morbidity and mortality, with comparable case fatality ratios during 1999 through 2013 (6.5%) and 1992 through 1998 (6.4%). Detection and treatment of syphilis early during pregnancy remain crucial to reducing CS morbidity and mortality.

Abstract
In many parts of the world particularly sub-Saharan Africa, congenital syphilis is a significant public health problem. Though it is rare in most affluent countries there has been a slight resurgence recently in several European countries. The diagnosis of suspected cases and management of congenital syphilis may be confusing and the potential for severe disability is high when cases are missed. The cornerstone of congenital syphilis control is antenatal screening and treatment of mothers with penicillin and in affluent countries it should be strengthened among those at high risk. In developing countries antenatal care screening needs to be strengthened by implementing point-of-care decentralised screening and treatment, also alternative novel approaches to control congenital syphilis should be looked at and utilized. International health agencies and political parties should take steps urgently to support focused approaches to tackling the problem of continuing congenital syphilis.

Abstract
Sexually transmitted infections (STIs) in Vietnam have been increasing. Control of STIs among female sex workers (FSWs) is important in controlling the epidemic. Effective STI control requires that physicians are skilful in taking sexual history for FSW patients. Three hundred and seventy-one physicians responded to a survey conducted in three provinces in Vietnam. The respondents were asked whether they asked FSW patients about their sexual history and information asked during sexual history taking. The respondents were also asked about their barriers for taking sexual history. Over one-fourth (27%) respondents always, over half (54%) respondents sometimes and 19% respondents never obtained a sexual history from FSW patients. Multivariable analysis revealed that factors associated with always taking a sexual history were being doctor, training in STIs and working at provincial level facilities. Physician’s discomfort was found to be inversely associated with training on communication with patients, seeing 15 or fewer patients a week, working at provincial level facilities. Issues in sexual history taking among FSW patients in general practice in Vietnam were identified. These issues can help STI control for FSW patients and need due attention in order to improve STI management in Vietnam.

Abstract
OBJECTIVE We sought to determine the clinical utility and cost of repeating syphilis testing in the third trimester of pregnancy in a high-risk urban population. STUDY DESIGN A retrospective cohort analysis was performed for patients delivering from January 1993 through December 2009 with at least 1 venereal disease research laboratory (VDRL) test sent during pregnancy. Chart review was performed for patients with confirmed syphilis to determine the temporal relationship of syphilis diagnosis to the pregnancy. For patients who seroconverted during pregnancy (no antecedent history or treatment for syphilis), newborn charts were reviewed. The costs of treating seropositive neonates and the costs of implementing additional third-trimester syphilis screening were then compared. RESULTS In the 17-year cohort, 58,569 deliveries were available for analysis. In all, 113 new cases of syphilis occurred (192.9/100,000 deliveries). There were 17 detected seroconversions; 10 were not rescreened in the third trimester and tested positive at delivery. These 10 patients may have benefitted from implementing uniform VDRL testing at 28-32 weeks' gestation. All newborns were asymptomatic with a negative workup and received empiric penicillin therapy. Based on 2011 hospital charges, the cost of evaluating and treating a neonate for syphilis is $11,079. Implementing an additional VDRL screen at 28-32 weeks' gestation for each pregnant patient during the 17 years studied would cost $1,991,346. An 18-fold increase in syphilis prevalence (3500/100,000 [3.5%] deliveries) would be required for the cost of implementation of universal early third-trimester screening to be equal to the potential health care charges saved by detecting maternal seroconversion and obviating the need for neonatal therapy. CONCLUSION In this high-risk population, additional syphilis screening in the third trimester is costly and is not clinically helpful in detecting maternal seroconversion.

Abstract
OBJETIVO: Analisar a assistência pré-natal na prevenção da transmissão vertical da sífilis. MÉTODOS: Estudo transversal representativo para as gestantes de baixo risco atendidas em unidades de saúde do município do Rio de Janeiro, RJ, período de 2007 a 2008. A identificação de gestantes com diagnóstico de sífilis na gestação foi feita por meio de entrevistas, verificação do cartão de pré-natal e busca de casos notificados em sistemas públicos de informação em saúde. Os casos de sífilis congênita foram identificados por meio de busca nos sistemas de informação em saúde: Sistema de Informação de Agravos de Notificação (Sinan), Sistema de Informação sobre Mortalidade (SIM) e Sistema de Informações Hospitalares (SIH) do SUS. RESULTADOS: Foram identificados 46 casos de sífilis na gestação e 16 casos de sífilis congênita com uma prevalência estimada de 1,9% (IC95% 1,3;2,6) de sífilis na gestação e de 6/1.000 (IC95% 3;12/1.000) de sífilis congênita. A taxa de transmissão vertical foi de 34,8% e três casos foram fatais, um abortamento, um óbito fetal e um óbito neonatal, com proporções elevadas de baixo peso e prematuridade. A trajetória assistencial das gestantes mostrou falhas na assistência, como início tardio do pré-natal, ausência de diagnóstico na gravidez e ausência de tratamento dos parceiros. CONCLUSÕES: Estratégias inovadoras, que incorporem melhorias na rede de apoio diagnóstico, são necessárias para enfrentamento da sífilis na gestação, no manejo clínico da doença na gestante e seus parceiros e na investigação dos casos como evento sentinela da qualidade da assistência pré-natal.

OBJETIVOS: avaliar a adequação das ações de controle da sífilis e do HIV na assistência pré-natal realizada em unidades do Sistema Único de Saúde do Município do Rio de Janeiro, Brasil. MÉTODOS: estudo transversal, realizado em 2007-2008, por meio de entrevistas com 2353 gestantes, análise de cartões de pré-natal e dados obtidos junto a 102 profissionais de saúde. Para avaliação da adequação da assistência foi elaborado um modelo lógico-operacional, tendo como referência normativa os protocolos assistenciais dos programas de assistência pré-natal e de DST/Aids do Ministério da Saúde. Foi considerado adequado o cumprimento de 100% das ações previstas para cada idade gestacional. RESULTADOS: foram identificadas falhas no aconselhamento das gestantes, na realização dos exames sorológicos, no tratamento dos casos de sífilis e na abordagem dos parceiros. Na análise bivariada, gestantes com início tardio da assistência pré-natal e número inadequado de consultas apresentaram pior adequação de todas as ações, exceto do aconselhamento anti-HIV. CONCLUSÕES: problemas no início precoce do prénatal, na garantia do número mínimo de consultas, no manejo adequado das gestantes e seus parceiros e, principalmente, no resultado sorológico oportuno da infecção pela sífilis e pelo HIV, são barreiras ao melhor controle da transmissão vertical dessas doenças.

Abstract
BACKGROUND Globally syphilis is an important yet preventable cause of stillbirth, neonatal mortality and morbidity. OBJECTIVES This review sought to estimate the effect of detection and treatment of active syphilis in pregnancy with at least 2.4 MU benzathine penicillin (or equivalent) on syphilis-related stillbirths and neonatal mortality. METHODS We conducted a systematic literature review of multiple databases to identify relevant studies. Data were abstracted into standardised tables and the quality of evidence was assessed using adapted GRADE criteria. Where appropriate, meta-analyses were undertaken. RESULTS Moderate quality evidence (3 studies) supports a reduction in the incidence of clinical congenital syphilis of 97% (95% c.i 93 - 98%) with detection and treatment of women with active syphilis in pregnancy with at least 2.4 MU penicillin. The results of meta-analyses suggest that treatment with penicillin is associated with an 82% reduction in stillbirth (95% c.i. 67 - 90%) (8 studies), a 64% reduction in preterm delivery (95% c.i. 53 - 73%) (7 studies) and an 80% reduction in neonatal deaths (95% c.i. 68 - 87%) (5 studies). Although these effect estimates were large and remarkably consistent across studies, few of the studies adjusted for potential confounding factors and thus the overall quality of the evidence was considered low. However, given these large observed effects and a clear biological mechanism for effectiveness the GRADE recommendation is strong. CONCLUSION Detection and appropriate, timely penicillin treatment is a highly effective intervention to reduce adverse syphilis-related pregnancy outcomes. More research is required to identify the most cost-effective strategies for achieving maximum coverage of screening for all pregnant women, and access to treatment if required.

Abstract
OBJECTIVE: To estimate the prevalence of missed opportunities for congenital syphilis and HIV prevention in pregnant women who had access to prenatal care and to assess factors associated to non-testing of these infections. METHODS: Cross-sectional study comprising a randomly selected sample of 2,145 puerperal women who were admitted in maternity hospitals for delivery or curettage and had attended at least one prenatal care visit, in Brazil between 1999 and 2000. No syphilis and/or anti-HIV testing during pregnancy was a marker for missed prevention opportunity. Women who were not tested for either or both were compared to those who had at least one syphilis and one anti-HIV testing performed during pregnancy (reference category). The prevalence of missed prevention opportunity was estimated for each category with 95% confidence intervals. Factors independently associated with missed prevention opportunity were assessed through multinomial logistic regression. RESULTS: The prevalence of missed prevention opportunity for syphilis or anti-HIV was 41.2% and 56.0%, respectively. The multivariate analysis showed that race/skin color (non-white), schooling (<8 years), marital status (single), income (<3 monthly minimum wages), having sex during pregnancy, history of syphilis prior to the current pregnancy, number of prenatal care visits (<6), and last prenatal visit before the third trimester of gestation were associated with an increased risk of missed prevention opportunity. A negative association with missed prevention opportunity was found between marital status (single), prenatal care site (hospital) and first prenatal visit in the third trimester of gestation. CONCLUSIONS: High rates of non-tested women indicate failures in preventive and control actions for HIV infection and congenital syphilis. Pregnant women have been discontinuing prenatal care at an early stage and are failing to undergo prenatal screening for HIV and syphilis.

Abstract
BACKGROUND To prevent congenital syphilis, the Centers for Disease Control and Prevention and professional organizations recommend universal prenatal syphilis screening. State-level or larger-scale evaluations of adherence to these guidelines have relied on administrative data. We measured prenatal syphilis screening rates in Indiana women with prenatal Medicaid coverage and also used electronic medical records to examine the completeness of syphilis screening claims in Medicaid administrative data. METHODS In statewide Indiana Medicaid claims data, diagnosis and procedure codes were used to identify women who delivered an infant between October 1, 1998, and September 30, 2002. Claims for prenatal (that is, during the 40 weeks before and including the delivery date) syphilis screens, including the "obstetric panel" of tests, and for prenatal visits were extracted. A subset of the study population received prenatal care in a large public hospital and its affiliated clinics served by an electronic medical records system. For these women, claims data were compared with laboratory reports. RESULTS Among 74,188 women with one delivery in Medicaid claims data, 60% had at least 1 prenatal syphilis screening claim, and 15% had 2 or more. Women with continuous Medicaid enrollment during pregnancy or with at least one prenatal visit claim had higher rates. Among the 3960 women for whom Medicaid claims and laboratory data were available, 49.8% had at least one prenatal syphilis screen in Medicaid claims, but 99.3% had at least one laboratory report of a syphilis screen. CONCLUSIONS Measurements made using Medicaid administrative data appear to substantially underestimate true prenatal syphilis screening rates.

Abstract
The availability of new diagnostic approaches, which are easier and faster to perform than conventional tests, offers the opportunity to improve the attention given to public health problems as syphilis. This study aimed to evaluate a rapid immunochromatographic strip test (Determine TP; Abbott Laboratories, Chicago, IL) and a nonequipment demanding particle microagglutination test (Serodia TP-PA; Fujirebio, Japan) for qualitative detection of treponemic antibodies. Sera from 548 women belonging to 3 population groups were tested; one of them showing low syphilis seroprevalence (1.5%) and the other 2 showing higher seroprevalences (>15%). By comparison with the gold standard (Venereal Disease Research Laboratories plus fluorescent treponemal antibody absorption), sensitivity and specificity values for both diagnostic tests were calculated. Sensitivity values of both tests evaluated were higher than 95% for 2 groups of 3 addressed; in one of the high syphilis prevalence groups, Serodia TP-PA showed 88.6% sensitivity. Specificity values were above 95% for all 3 groups. The use of simple/rapid treponemic tests as those included here may prove to be a suitable replacement for the traditional syphilis serology diagnosis approach, particularly at primary care settings.

Abstract
OBJECTIVES Black and Hispanic infants are 19.9 and 10.3 times more likely, respectively, than white infants to develop congenital syphilis (CS), a disease that is preventable with timely prenatal screening and treatment. We examined racial/ethnic group differences in prenatal syphilis screening among pregnant women with equal financial access to prenatal care through Medicaid. METHODS We used Florida claims data to examine any, early, and repeat screening among non-Hispanic white, non-Hispanic black, and Hispanic women with Medicaid-covered deliveries in FY1995 (n=56,088) and FY2000 (n=54,073). We estimated screening rates for each group, and used logistic regression to assess whether screening disparities remained after controlling for other factors, including Medicaid enrollment characteristics and prenatal care source, and associations between access-related factors and screening odds for each group. RESULTS Between FY1995 and FY2000, rates of any and early syphilis screening increased, while repeat screening rates decreased. In FY1995, any, early, and repeat rates were highest for blacks and lowest for Hispanics. In FY2000, any and early screening rates were highest for whites and lowest for blacks, while repeat screening rates were similar across groups. Racial/ethnic differences in any and early screening remained for non-Hispanic blacks after adjustment. In general, Medicaid enrollment early in pregnancy, primary care case management participation, and use of a safety net clinic were associated with higher screening odds, though results varied by test type and across groups. CONCLUSIONS Unexplained racial/ethnic disparities in prenatal syphilis screening remain for blacks, but not Hispanics. Individual, provider, and program factors contribute to differences across and within groups.

Abstract
In every society, congenital syphilis (CS) has significant medical, economic, societal and emotional burdens; these are poorly characterized but high. Inexplicably, the elimination of CS has failed to attract international attention. Yet, the cornerstones of programs to do this universally are in place, the recent development of new diagnostic tools offers the now-practical possibility of testing every pregnant woman, testing is cost-effective, and programs for the elimination of CS can be joined with other programs to enhance efficiency. The magnitude of the CS burden, globally, rivals that of HIV infection in neonates yet receives little attention. The newly proposed World Health Organization Strategy for the Global Elimination of Congenital Syphilis aims to mobilize resources and provide a plan to address this under-recognized health problem.

Abstract
BACKGROUND AND OBJECTIVES Building upon a critical assessment of national policies, programs, and treatment options, the World Health Organization (WHO) recently developed an action plan for the elimination of congenital syphilis (CS). The objective of the review was to identify areas of commonality or divergence between the national strategies and the WHO plan, thereby helping to target the development of national-level policies in light of the forthcoming recommendations of the proposed WHO action plan to eliminate CS. STUDY DESIGN The 4 strategic pillars of the proposed WHO action plan were used as a comparative framework to examine the policy, programmatic, and monitoring components of a sample of 14 existing national-level congenital or maternal control policies. The countries were chosen to represent a range of resource and prevalence levels. RESULTS The majority of countries do not meet every element proposed in the WHO action plan. Political commitment (pillar 1) across the 14 countries is varied. CS elimination goals were rare but all had universal screening. Linkages to appropriate case management services were identified in 11 countries, although a national governing body was not generally evident. Efforts to increase and improve access to care (pillar 2) were noted in 8 countries with recommendations to ensure all pregnant women were screened and treated. Low-resource settings have formed international partnerships. Guidelines for the diagnosis and treatment of pregnant women and partners (pillar 3) found in high-resource settings were lacking in low-resource and high CS prevalence countries. Surveillance programs were active in 10 countries while comprehensive details on monitoring and evaluation (pillar 4) components including proxy CS indicators were unavailable for nearly all. CONCLUSIONS The elimination of CS can be achieved through the implementation of a series of proven measures but requires technical support, funding, and a commitment among political forces, health officials, and the public to prevent and treat all CS cases and help countries reach their Millennium Development Goals. Stronger partnerships with clearly defined responsibilities should be developed among agencies responsible for national STI control, HIV/AIDS control, and Making Pregnancy Safer initiatives to ensure the universal coverage of CS control interventions.

Abstract
OBJECTIVE The objective of this study was to assess the rate of prenatal syphilis screening and compliance with clinical guidelines on the receipt of early and repeat screening in a Medicaid population before and after implementation of the National Plan to Eliminate Syphilis. STUDY DESIGN Rates of office- and clinic-based prenatal syphilis screening among pregnant women with Medicaid-covered deliveries in Florida in fiscal years (FYs) 1995 and 2000 are analyzed using Medicaid claims data. RESULTS The proportions of women receiving any, early, and repeat prenatal syphilis screening increased sharply between FY 1995 and FY 2000 but remain well below recommended levels. Screening is highly correlated with timing of prenatal care and Medicaid enrollment duration. CONCLUSIONS Further efforts to improve screening rates will need to both increase the proportion of women who receive timely prenatal care and ensure that providers comply with guidelines to provide syphilis screening as a component of prenatal care for all women.

Abstract
OBJECTIVES AND GOAL This study was designed to evaluate the extent to which pregnant women in a community with a high syphilis incidence were screened for syphilis according to standard recommendations of twice during prenatal care and at labor and delivery. STUDY DESIGN Labor and delivery records from 4 hospitals in Miami-Dade County, Florida, were abstracted to obtain maternal and prenatal care characteristics and syphilis screening practices. RESULTS Of the 1991 women, records indicated that 1655 (83%) were screened at least once during prenatal care, 220 (11%) were screened twice during prenatal care before delivery, and 184 (9%) were screened twice during prenatal care and at delivery. Attending a private clinic, having more than adequate prenatal care and having private insurance were associated with not being screened at least twice before delivery. CONCLUSIONS Few women were screened according to standard recommendations, and provider or institutional-related factors affected adequacy of screening.

Abstract
Charts of newborn infants were reviewed for documentation of maternal risk factors and prenatal screening test results. Physician documentation was incomplete in most infants. Nearly half of all infants were discharged without documentation regarding maternal status of hepatitis B, syphilis, and group B streptococcus. These lapses in newborn assessment have a potential for significant medical errors.

Abstract
OBJECTIVES To measure the coverage of antenatal syphilis screening and identify factors related to women not being screened. GOAL To assess the syphilis control program in Mongolia. STUDY DESIGN Antenatal care records of women in 16 antenatal care clinics of 6 districts were reviewed. Additionally, postpartum women were interviewed to identify potential factors for not being screened. RESULTS Among 3,519 antenatal records, the coverage of syphilis screening was 77.7%. Of 2,735 screened women, 54 (2.0%) had reactive serological results and subsequently received treatment. Four late antenatal care comers delivered infants with congenital syphilis. Being unscreened was significantly associated with late antenatal care (odds ratio OR=2.6), lack of knowledge (OR=5.5), history of previous sexually transmitted infection (OR=3.7), and living far from screening services (OR=4.9). CONCLUSIONS The coverage of antenatal syphilis screening is still low, with poor contact tracing. More efforts are needed to promote early antenatal care visit and improve syphilis screening systems.

Abstract
OBJECTIVE To describe the incidence of maternal syphilis and the corresponding rate of infection in exposed neonates in British Columbia before and after a serious outbreak of infectious syphilis in the heterosexual population. METHODS We conducted a retrospective chart review of pregnant women with positive syphilis serology and reported cases of congenital syphilis in British Columbia from 1994 to 2003. Clinical charts were reviewed for demographic information, staging of maternal syphilis, and stage of pregnancy when treatment was received. The primary outcome measure was the number of cases of congenital syphilis. We conducted a 2-sided z-test and Fisher's exact test to determine differences in the proportion of infectious syphilis in mothers and the number of cases of congenital syphilis before and during the major outbreak. RESULTS In 389 478 live births in British Columbia between 1994 and 2003, 77% of mothers had prenatal syphilis serology. A diagnosis of syphilis was made in 183 mothers, resulting in 5 cases of congenital syphilis. Four of these were in infants whose mothers did not undergo prenatal syphilis testing. The proportion of pregnant women with infectious syphilis was significantly higher after the onset of a major outbreak of syphilis in the community than it was before (P = 0.001), but there was no significant difference in the number of cases of congenital syphilis (3 before and 2 after the outbreak, P = 0.36). CONCLUSION Although syphilis rates in British Columbia during the study period rose steadily, the prevalence of congenital syphilis remained low. Our findings suggest that, in the context of a major outbreak, universal screening and prenatal syphilis testing may contribute to controlling rates of congenital syphilis.

Abstract
BACKGROUND Behavioral and socioeconomic factors create considerable obstacles to the elimination of congenital syphilis. A clear understanding of maternal risk factors is important to define interventions in every community. GOAL The goal of this study was to investigate maternal risk factors for congenital syphilis. STUDY DESIGN We conducted a case-control and descriptive analysis of 3 groups of live born infants and their mothers consisting of: group I (cases of congenital syphilis), group II (neonates without congenital syphilis whose mothers had been adequately treated for syphilis), and group III (random sample of newborn infants whose mothers have not had syphilis). Data were prospectively collected from personal interview and antenatal records. RESULTS In the case-control study, including groups I and III, the maternal characteristics independently associated with congenital syphilis in the logistic regression were monthly per capita income under 30 US dollars (odds ratio [OR], 2.8; 95% confidence interval [CI], 1.1-7.4), single status (OR, 2.8; 95% CI, 1.1-7.8), and less than 6 prenatal visits (OR, 3.2; 95% CI, 1.3-8.1). Comparison between groups I and II (only mothers who have had syphilis) showed a strong protective association of prenatal care with congenital syphilis (OR, 0.05; 95% CI, 0.00-0.39). Additional analysis identified 2 separate profiles of maternal characteristics, one consisting of low socioeconomic status and the other of risk behaviors. Some women who had syphilis before or during pregnancy received adequate prenatal care and delivered infants without congenital syphilis. Most of these women had high-risk behaviors but they were, in general, less poor, older, and more educated than mothers of infants with congenital syphilis. CONCLUSIONS Risk behaviors and low socioeconomic characteristics constituted 2 separate maternal profiles associated with congenital syphilis. Socioeconomic risk factors interfered more with prenatal care. To become more effective, the strategies for prevention of congenital syphilis should be targeted to each maternal profile.

Abstract
OBJECTIVE The purpose of this study was to assess the frequency and pattern of state laws or regulations regarding prenatal syphilis serologic screening in the United States in 2001. STUDY DESIGN We surveyed the United States for existing laws and regulations regarding serologic screening for syphilis during pregnancy. Testing was compared with 2000 state rates of syphilis in women and newborn infants, with states that had syphilis high morbidity areas, and with national 2000 and 2010 objectives for rates of syphilis. RESULTS Forty-six of the 50 states (90%) and the District of Columbia have laws regarding antenatal syphilis screening. Thirty-four of the 46 statutes (76%) mandate one prenatal test, usually at the first prenatal visit or early in pregnancy. Twelve laws (26%) include third-trimester testing for all or high-risk women. The presence of high morbidity areas, incidence of early syphilis in women, and rates of congenital syphilis are associated with increasing frequency of legislated antepartum screening. CONCLUSION Only 90% of states have statutes that require antepartum syphilis screening, and there is variation in the content of the statutes about the number and timing of tests. States with a heavy burden of infectious syphilis in women tend to require more prenatal testing.
