RESUMO
BACKGROUND: Congenital syphilis disproportionately affects individuals impacted by adverse social determinants of health. Understanding these determinants may help facilitate holistic care. METHODS: We performed a retrospective review of mother-infant dyads with potential congenital syphilis in a Missouri hospital system. Cases were classified per Centers for Disease Control and Prevention clinical scenarios. Information was collected regarding demographics, prenatal care, substance use, and other social factors. Dyads with confirmed/highly probable or possible congenital syphilis ("congenital syphilis outcomes") were compared to those with less likely/unlikely congenital syphilis ("non-congenital syphilis outcomes") using descriptive statistics. RESULTS: We identified 131 dyads with infant dates of birth from 12/2015-6/2022: 74 (56%) with congenital syphilis outcomes and 56 (43%) with non-congenital syphilis outcomes. Most mothers were Black/African American (n = 84, 65%) and lived in areas with high Social Vulnerability Indices. Many had inadequate prenatal care (n = 61, 47%) and/or substance use histories (n = 55, 42%). Significant associations with congenital syphilis outcomes included limited prenatal care (OR 3.01, 95% CI 1.38-6.56), no prenatal care (OR 16.08, 95% CI 1.96-132.11), substance use (OR 3.42, 95% CI 1.61-7.25), housing instability (OR 3.42, 95% CI 1.39-8.38), and justice system interactions (OR 2.29, 95% CI 1.00-5.24). Substance use correlated with prenatal care adequacy (p < 0.001). 30% of infants with congenital syphilis outcomes were taken into protective custody. CONCLUSIONS: Adverse social determinants of health are common in dyads impacted by congenital syphilis. Health systems should consider interdisciplinary programming to improve testing and linkage to care. Future studies should evaluate social support for congenital syphilis prevention and management.
RESUMO
Objective. To compare HIV drug resistance in pregnant women with perinatal HIV (PHIV) and those with nonperinatal HIV (NPHIV) infection. Methods. We conducted a multisite cohort study of PHIV and NPHIV women from 2000 to 2014. Sample size was calculated to identify a fourfold increase in antiretroviral (ARV) drug resistance in PHIV women. Continuous variables were compared using Student's t-test and Wilcoxon rank-sum tests. Categorical variables were compared using χ (2) and Fisher's exact tests. Univariate analysis was used to determine factors associated with antiretroviral drug resistance. Results. Forty-one PHIV and 41 NPHIV participants were included. Women with PHIV were more likely to have drug resistance than those with NPHIV ((55% versus 17%, p = 0.03), OR 6.0 (95% CI 1.0-34.8), p = 0.05), including multiclass resistance (15% versus 0, p = 0.03), and they were more likely to receive nonstandard ARVs during pregnancy (27% versus 5%, p = 0.01). PHIV and NPHIV women had similar rates of preterm birth (11% versus 28%, p = 0.08) and cesarean delivery (47% versus 46%, p = 0.9). Two infants born to a single NPHIV woman acquired HIV infection. Conclusions. PHIV women have a high frequency of HIV drug resistance mutations, leading to nonstandard ARVs use during pregnancy. Despite nonstandard ARV use during pregnancy, PHIV women did not experience increased rates of adverse pregnancy outcomes.

BACKGROUND: Independent risk factors for surgical site infection (SSI) after cesarean section have not been well documented, despite the large number of cesarean sections performed and the relatively common occurrence of SSI. OBJECTIVE: To determine independent risk factors for SSI after low transverse cesarean section. DESIGN: Retrospective case-control study. SETTING: Barnes-Jewish Hospital, a 1,250-bed tertiary care hospital. PATIENTS: A total of 1,605 women who underwent low transverse cesarean section during the period from July 1999 to June 2001. METHODS: Using the International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes for SSI or wound complication and/or data on antibiotic use during the surgical hospitalization or at readmission to the hospital or emergency department, we identified potential cases of SSI in a cohort of patients who underwent a low transverse cesarean section. Cases of SSI were verified by chart review using the definitions from the Centers for Disease Control and Prevention's National Nosocomial Infections Surveillance System. Control patients without SSI or endomyometritis were randomly selected from the population of patients who underwent cesarean section. Independent risk factors for SSI were determined by logistic regression. RESULTS: SSIs were identified in 81 (5.0%) of 1,605 women who underwent low transverse cesarean section. Independent risk factors for SSI included development of subcutaneous hematoma after the procedure (adjusted odds ratio [aOR], 11.6 [95% confidence interval [CI], 4.1-33.2]), operation performed by the university teaching service (aOR, 2.7 [95% CI, 1.4-5.2]), and a higher body mass index at admission (aOR, 1.1 [95% CI, 1.0-1.1]). Cephalosporin therapy before or after the operation was associated with a significantly lower risk of SSI (aOR, 0.2 [95% CI, 0.1-0.5]). Use of staples for skin closure was associated with a marginally increased risk of SSI. CONCLUSIONS: These independent risk factors should be incorporated into approaches for the prevention and surveillance of SSI after surgery.

BACKGROUND: Disseminated mycobacterial disease is an important cause of morbidity and mortality in patients with HIV-infection. Nonspecific clinical presentation makes the diagnosis difficult and sometimes neglected. METHODS: We conducted a retrospective cohort study to compare the presentation of disseminated Mycobacterial tuberculosis (MTB) and non-tuberculous Mycobacterial (NTM) disease in HIV-positive patients from 1996 to 2006 in Brazil. RESULTS: Tuberculosis (TB) was diagnosed in 65 patients (67.7%) and NTM in 31 (32.3%) patients. Patients with NTM had lower CD4 T cells counts (median 13.0 cells/mm3 versus 42.0 cells/mm3, P = 0.002). Patients with tuberculosis had significantly more positive acid-fast smears (48.0% vs 13.6%, P = 0.01). On chest X-ray, miliary infiltrate was only seen in patients with MTB (28.1% vs. 0.0%, P = 0.01). Pleural effusion was more common in patients with MTB (45.6% vs. 13.0%, P = 0.01). Abdominal adenopathy (73.1% vs. 33.3%, P = 0.003) and splenic hypoechoic nodules (38.5% vs. 0.0%, P = 0.002) were more common in patients with TB. CONCLUSION: Miliary pulmonary pattern on X-ray, pleural effusion, abdominal adenopathy, and splenic hypoechoic nodules were imaging findings associated with the diagnosis of tuberculosis in HIV-infected patients. Recognition of these imaging features will help to distinguish TB from NTM in AIDS patients with fever of unknown origin due to disseminated mycobacterial disease.

OBJECTIVE: To examine the association of clinical chorioamnionitis on cesarean delivery in a national sample of hospital discharges. DATA SOURCE: Hospital discharge data from the 1998-2010 Nationwide Inpatient Sample. STUDY DESIGN: We performed a cross-sectional study and general linear modeling was used to determine the association of clinical chorioamnionitis on risk of cesarean delivery. PRINCIPAL FINDINGS: A total of 10,843,682 deliveries and 51,799,431 nationally weighted deliveries were identified. Clinical chorioamnionitis was present in 2.9 percent of cesarean and 1.3 percent of vaginal deliveries (p < .001). In multivariate analysis, clinical chorioamnionitis was associated with a 1.39-fold increased risk of cesarean delivery. Compared with women without clinical chorioamnionitis at an urban/teaching hospital, women with clinical chorioamnionitis at an urban/teaching, urban/nonteaching, and rural hospital were 1.4-1.5 times more likely to have cesarean delivery. Compared with women without clinical chorioamnionitis in the Midwest, the relative risk for cesarean in women with clinical chorioamnionitis was 1.54 for women in the South, 1.47 in the Northeast, 1.39 in the Midwest, and 1.34 in the West. CONCLUSIONS: Women with clinical chorioamnionitis were more likely to have cesarean delivery than those without clinical chorioamnionitis, and the risk of cesarean delivery varied significantly by hospital location, teaching status, and U.S. region.

INTRODUCTION: Smear-negative pulmonary TB (SNPT) represents 30-60% of all pulmonary TB cases. The mortality of these patients can reach 25% in populations with high prevalence of HIV infection, and 10-20% of TB transmission at the population level are attributable to SNPT cases. METHODS: We conducted a retrospective study to evaluate epidemiological, clinical, and radiological characteristics of patients with SNPT and to compare these with patients who were diagnosed as having smear-positive pulmonary TB (SPPT). All adult patients (≥ 18 years old) with a positive culture for Mycobacterium tuberculosis, and a diagnosis of pulmonary TB were included in the study. RESULTS: 198 patients met the inclusion criteria (positive culture for Mycobacterium tuberculosis) and were included in the analysis. Of these patients, 69 (34.8%) were smear positive (SPPT) and 129 (65.2%) were smear negative (SNPT). In univariate analysis, cough, dyspnea, and hemoptysis were less frequent in SNPT patients in comparison with SPPT patients. In a multivariate model, having no cough and no radiographic pattern typical of TB were the characteristics independently associated with a diagnosis of SNPT. CONCLUSIONS: We found a very high prevalence of SNPT among patients with TB in a setting with high TB and HIV prevalence. The absence of cough in the presence of other symptoms suggestive of TB, and having no radiographic pattern typical of TB where independent predictors of SNPT.

Correct diagnosis of parasitic infections is essential for the treatment of individuals avoiding indiscriminate use of anthelmintics which increases drug resistance. In a comparative study between the spontaneous sedimentation technique and Paratest(®), 140 stool samples were analyzed for the detection of parasites. The prevalence was 12.7% obtained by the spontaneous sedimentation method but only 5.7% using Paratest(®). Paratest(®) has shown a high proportion of false-negative results, lower sensitivity and negative predictive values compared with the spontaneous sedimentation method. Further optimization and studies of the Paratest(®) method are necessary for wider use in clinical diagnosis.

Introduction: Tuberculosis (TB) persists as a severe global public health issue. The aim of the present study was to evaluate the performance of an in-house TB PCR (polymerase chain reaction) in sputum. Methods: DNA from sputum specimens were submitted to a nested-PCR protocol for the IS6110 region detection. PCR results were compared to those of the traditional methods for TB diagnosis, i.e., acid-fast bacilli (AFB) smear microscopy and culture. We analyzed sputum samples obtained from 133 patients. Results: A total of 48 (36%) cultures yielded indeterminate results due to contamination. This high contamination rate may be explained by the fact that samples from fibrocystic patients were included in this study. Additionally, other five samples were positive for nontuberculous mycobacteria (NTM). Therefore, it was possible to compare 80 patients for M. tuberculosis detection. We found 14 positive samples: five presented positive results in the three methods (5/14; 35.7%), two were positive in culture and PCR (2/14; 14.3%), one was positive in AFB and PCR (1/14; 7.1%), five were positive only in PCR (5/14; 35.7%) and 1 was positive only in culture (1/14; 7.1%). Thus, positivity rates for each technique were: 7.5% for AFB (6/80), 10% for culture (8/80) and 16.25% for PCR (13/80). Among the 48 patients who had indeterminate results in sputum culture, two samples were positive in PCR. Conclusion: Considering the limitations of the traditional methods, the use of PCR as a molecular technique could be advantageous for TB diagnosis.

BACKGROUND: Accurate data on costs attributable to hospital-acquired infections are needed to determine their economic impact and the cost-benefit of potential preventive strategies. OBJECTIVE: To determine the attributable costs of surgical site infection (SSI) and endometritis (EMM) after cesarean section by means of 2 different methods. DESIGN: Retrospective cohort. SETTING: Barnes-Jewish Hospital, a 1,250-bed academic tertiary care hospital. PATIENTS: There were 1,605 women who underwent low transverse cesarean section from July 1999 through June 2001. METHODS: Attributable costs of SSI and EMM were determined by generalized least squares (GLS) and propensity score matched-pairs by means of administrative claims data to define underlying comorbidities and procedures. For the matched-pairs analyses, uninfected control patients were matched to patients with SSI or with EMM on the basis of their propensity to develop infection, and the median difference in costs was calculated. RESULTS: The attributable total hospital cost of SSI calculated by GLS was $3,529 and by propensity score matched-pairs was $2,852. The attributable total hospital cost of EMM calculated by GLS was $3,956 and by propensity score matched-pairs was $3,842. The majority of excess costs were associated with room and board and pharmacy costs. CONCLUSIONS: The costs of SSI and EMM were lower than SSI costs reported after more extensive operations. The attributable costs of EMM calculated by the 2 methods were very similar, whereas the costs of SSI calculated by propensity score matched-pairs were lower than the costs calculated by GLS. The difference in costs determined by the 2 methods needs to be considered by investigators who are performing cost analyses of hospital-acquired infections.

OBJECTIVE: To determine independent risk factors for endometritis after low transverse cesarean delivery. STUDY DESIGN: We performed a retrospective case-control study during the period from July 1999 through June 2001 in a large tertiary care academic hospital. Endometritis was defined as fever beginning more than 24 hours or continuing for at least 24 hours after delivery plus fundal tenderness in the absence of other causes for fever. Independent risk factors for endometritis were determined by means of multivariable logistic regression. A fractional polynomial method was used to examine risk of endometritis associated with the continuous variable, duration of rupture of membranes. RESULTS: Endometritis was identified in 124 (7.7%) of 1,605 women within 30 days after low transverse cesarean delivery. Independent risk factors for endometritis included age (odds ratio [OR] for each additional year, 0.93 [corrected] [95% confidence interval {CI}, 0.90-0.97]) and anemia or perioperative blood transfusion (OR, 2.18 [CI, 1.30-3.68]). Risk of endometritis was marginally associated with a proxy for low socioeconomic status, lack of private health insurance (OR, 1.72 [CI, 0.99-3.00]); with amniotomy (OR, 1.69 [CI, 0.97-2.95]); and with longer duration of rupture of membranes. CONCLUSION: Risk of endometritis was independently associated with younger age and anemia and was marginally associated with lack of private health insurance and amniotomy. The odds of endometritis increased approximately 1.7-fold within 1 hour after rupture of membranes, but increased duration of rupture was only marginally associated with increased risk. Knowledge of these risk factors can guide selective use of prophylactic antibiotics during labor and heighten awareness of the risk in subgroups at highest risk of infection.

We used administrative and clinical data from a case-control study to calculate the costs of surgical site infection and endometritis after cesarean delivery. Attributable costs determined by multivariate generalized least-squares regression models with the 2 data sets were similar, suggesting that administrative data can be used to calculate infection costs.

OBJECTIVES: To examine demographic and behavioral characteristics in incarcerated women to determine which characteristics are associated with prevalent sexually transmitted infections (STIs). STUDY DESIGN: A cross-sectional analysis of data of 205 women entering jail in Rhode Island was performed as part of a study evaluating a family planning program. Women were recruited near time of commitment, and inclusion was limited to women at risk for an unplanned pregnancy. Incarcerated women were interviewed by a research assistant for demographic information, psychosocial and behavioral characteristics. Self-collected vaginal swabs were tested for STIs, including Neisseria gonorrhoeae and Chlamydia trachomatis by polymerase chain reaction and Trichomonas vaginalis by InPouch culture. Relative risks (RRs) were estimated using Poisson regression. RESULTS: Sixty-eight of 205 patients tested positive for an STI [33%; 95% confidence interval (CI) 27-40%]. Forty-five patients (26%) tested positive for T. vaginalis, 27 (14%) were positive for C. trachomatis, and 21 (11%) were positive for N. gonorrhoeae. On bivariate analysis, 6 or more sexual partners in the last year (RR 1.84; 95% CI 1.01-3.36), exchanging sex for drugs/money (RR 1.65; 95% CI 1.01-2.69), and homelessness (RR 1.82; 95% CI 1.07-3.09) were associated with STI. After adjustment for age, race/ethnicity, education, and other covariates, none of the factors was significantly associated with STI. CONCLUSIONS: The prevalence of STI in this jail population is high. Incarceration represents a unique opportunity to evaluate and treat this underserved population. Predictors of infection are limited and infection is common; therefore, routine screening should be considered in this population.
