The Importance of Community-Based and Community-Partnered COVID-19 Testing for Reducing Disparities Among African American Populations.

Background: Health inequalities in African American communities have been further exacerbated by COVID-19. Public health departments and other safety-net providers across the United States have partnered with community-based organizations to address barriers to COVID-19 testing in disproportionately impacted communities. This narrative review summarizes lessons learned from published examples of these community-based COVID-19 testing efforts. Methods: We searched online databases for peer-reviewed articles on community-based COVID-19 testing interventions in the United States aimed at increasing COVID-19 testing among African American populations. We abstracted information about each example and synthesized the primary lessons learned and key aspects that contributed to their success. Results: Seven examples of community-based COVID-19 testing aimed at increasing testing among African Americans and other underserved populations were identified and described, across various U.S. locations and involving multiple types of partners (1) St. Paul, MN (faith, health centers, Mayo Clinic); (2) Chicago, IL (university hospital and health centers); (3) NC (health centers, Community Advisory Board); (4) Baltimore, MD (hospitals, community clinic, mobile clinic); (5) Marion County, FL (health department and community partners); (6) New Orleans, LA (health department and health system); and (7) New York City, NY health and hospital system, mobile clinic). Discussion: Several key aspects of the COVID-19 testing models included the following: (1) close proximity of the testing site to affected communities and availability of walk-up and drive-through testing options; (2) partnerships between safety-net providers and broad community networks, which facilitated outreach and trust; (3) increased resources for safety-net providers; and (4) the use of data to identify areas of need and track impact. The merging of resources and relationships among well-equipped, safety-net providers and other health care institutions and culture-rich, community-centered organizations, to jointly address structural and systemic inequities, is key to cultivating health equity in the distribution of COVID-19 testing and other essential public health services.

Resident microbes shape the vaginal epithelial glycan landscape.

Epithelial cells are covered in carbohydrates (glycans). This glycan coat or "glycocalyx" interfaces directly with microbes, providing a protective barrier against potential pathogens. Bacterial vaginosis (BV) is a condition associated with adverse health outcomes in which bacteria reside in direct proximity to the vaginal epithelium. Some of these bacteria, including Gardnerella, produce glycosyl hydrolase enzymes. However, glycans of the human vaginal epithelial surface have not been studied in detail. Here, we elucidate key characteristics of the "normal" vaginal epithelial glycan landscape and analyze the impact of resident microbes on the surface glycocalyx. In human BV, glycocalyx staining was visibly diminished in electron micrographs compared to controls. Biochemical and mass spectrometric analysis showed that, compared to normal vaginal epithelial cells, BV cells were depleted of sialylated N- and O-glycans, with underlying galactose residues exposed on the surface. Treatment of primary epithelial cells from BV-negative women with recombinant Gardnerella sialidases generated BV-like glycan phenotypes. Exposure of cultured VK2 vaginal epithelial cells to recombinant Gardnerella sialidase led to desialylation of glycans and induction of pathways regulating cell death, differentiation, and inflammatory responses. These data provide evidence that vaginal epithelial cells exhibit an altered glycan landscape in BV and suggest that BV-associated glycosidic enzymes may lead to changes in epithelial gene transcription that promote cell turnover and regulate responses toward the resident microbiome.

Correlates of HIV-Related Stigmas Among African American Church-Affiliated Populations in Kansas City.

HIV-related stigmas contribute to disparities, and contact with HIV-positive individuals has been suggested to reduce stigma. Faith-based organizations have been recognized as important to stigma reduction efforts among African American populations; however, relatively few church-based studies have measured HIV-related stigma. This study uses baseline data (N = 1,448) from a study with 14 African American churches in Kansas City, Missouri and Kansas, to examine correlates of HIV-related stigmas among church members and community members accessing church social services using two previously validated scales that measure discomfort interacting with individuals with HIV and anticipated stigma or rejection. Knowing someone with HIV was associated with lower discomfort, even after adjusting for sociodemographic characteristics and sexual risk, HIV knowledge, previous communication about HIV at church, and mean drug and homosexuality stigmas. Knowing someone with HIV was not associated with anticipated stigma or rejection after adjustment. Contact-based interventions hold promise for reducing discomfort around people with HIV among church-affiliated populations.

COVID-19 Testing in African American Churches Using a Faith-Health- Academic Partnership.

Increasing access to COVID-19 testing in influential, accessible community settings is needed to address COVID-19 disparities among African Americans. We describe COVID-19 testing intervention approaches conducted in Kansas City, Missouri, African American churches via a faith-health-academic partnership. Trained faith leaders promoted COVID-19 testing with church and community members by implementing multilevel interventions using a tailored toolkit and standard education information. The local health department conducted more than 300 COVID-19 tests during or after Sunday church services and outreach ministry activities. (Am J Public Health. 2022;112(S9):S887-S891. https://doi.org/10.2105/AJPH.2022.306981).

The Role of Labor Induction in Racial Disparities in Cesarean Delivery.

We examined the interaction between race and labor induction in cesarean delivery in a cohort of 600,000 deliveries in the Cerner Health Facts database. Black women had higher likelihood cesarean (28.9 vs. 26.5%) and lower likelihood of induction of labor at delivery compared to white women (27.2 vs. 32.5%). Induction modified the association between race and cesarean-Black women (odds ratio=1.36, 95% confidence interval 1.30, 1.43) who were induced had significantly increased odds of cesarean delivery.

The effect of race and supplementation on maternal and umbilical cord plasma folates.

OBJECTIVE: The purpose of this study is to test the hypothesis that race and supplementation affect the concentration and correlation of various folate species in maternal and umbilical cord blood. METHODS: This is a single-center, prospective, cross-sectional cohort of cord blood samples obtained from 40 uncomplicated term pregnancies as a pilot study, following a protocol approved by the Institutional Review Board. High performance liquid chromatography mass spectrometry quantitated the following concentrations in extracted plasma samples: 5-methyltetrahydrofolate (5MTHF), 5,10-methenyl-tetrahydrofolate (5,10-MeTHF), tetrahydrofolate (THF), and unmetabolized folic acid. RESULTS: Folate concentrations in the umbilical cord plasma were consistently higher than maternal samples for 5MTHF (p < .001), 5,10-MeTHF (p < .001), and THF (p < .001); cord blood folic acid levels, however, were lower than maternal samples (p < .03). While 5MTHF was the most prevalent folate, ratios comparing cord blood to maternal blood folates suggests a fourfold preponderance of THF in cord blood folate signature, a trend unchanged by supplementation. Prenatal supplementation increased the concentrations of 5MTHF, for both maternal (p < .01) and cord blood samples (p < .005). In comparison to the other two racial groups, African American 5MTHF concentration demonstrated a lower total folate concentration in both maternal samples and cord blood samples, in addition to a relatively blunted response to supplementation. A significantly positive correlation between maternal and cord blood 5MTHF concentration was noted in all three racial groups. Supplementation resulted in a positive correlation between maternal and cord blood 5MTHF concentrations (r = 0.85, p < .0001). CONCLUSIONS: 5MTHF is the most prevalent folate in both cord and maternal plasma, and race and supplementation primarily affect variations in maternal and fetal 5MTHF concentrations and their correlation with each other. However, the greater concentration of THF in cord blood relative to maternal blood offers preliminary insight into the importance of how folate metabolism differs in the specific context of fetal development and physiology, with greater emphasis on DNA synthesis and stability. Furthermore, supplementation appeared to not have as great an impact on African American maternal or cord blood folates, suggesting a variable benefit of current repletion strategies to certain subsets of the population. Future studies that further elucidate these differences and their impact on birth outcomes may help inform supplementation protocols that are more personalized, with greater efficacy in promoting positive perinatal outcomes.

Menstruation and contraception patterns of female adolescent transplant recipients.

BACKGROUND: There is a lack of knowledge regarding menstrual cycles and contraception usage for adolescent transplant patients and families. Solid organ transplant patients start teratogenic medications which have pregnancy implications. We explore adolescent female solid organ transplant recipient and guardian's contraceptive knowledge and attitudes as well as menstrual patterns. METHODS: A cross-sectional descriptive research design was utilized to collect information from adolescent female transplant patients who are on mycophenolate mofetil after solid organ transplant and their guardians within our freestanding children's hospital via a survey. The sample consisted of all female adolescent patients who have completed a solid organ transplant and are on mycophenolate mofetil from April 2016 through May 2017. RESULTS: Twenty-one patients were approached, of which nineteen patients and seventeen guardians completed the survey. The average age of the patient was 16.2 years. The average age at time of transplant was 12.2 years. The type of transplants includes renal (57.1%), heart (23.8%), and liver (4.8%). There were six patients (33.3%) who had a history of sexual activity; among these patients, the mean number of partners in the last year was 1.2. Menstrual concerns included dysmenorrhea, irregular bleeding, and heavy bleeding pre- and post-transplant, respectively. Participants reported contraceptive counseling prior to and after transplant approximately half of the time. CONCLUSIONS: Adolescent solid organ transplant patients have multiple reproductive needs including contraception, dysmenorrhea, and irregular bleeding. Integration of contraceptive knowledge into clinical care received by adolescents with solid organ transplants is supported by knowledge gained through this study.

Variability in Price of Generic Antipsychotic Medications at Community Pharmacies.

OBJECTIVE: This study aimed to examine variability in pricing of generic antipsychotic medications in a diverse metropolitan area and to determine whether prices varied by pharmacy type. METHODS: A cross-sectional survey was conducted of pharmacy-level variability in retail cash prices for a 30-day supply of one first-generation and five generically available second-generation antipsychotic medications at community pharmacies in the Kansas City metropolitan area. All community pharmacies in the area were identified (N=281), and 94% (N=265, with 147 in Missouri and 118 in Kansas) responded to phone queries between April 25 and May 25, 2017, requesting the cash price of a 30-day supply of each of the six antipsychotics. All included pharmacies were categorized as a nationwide chain (N=182), grocery store (N=53), or independent pharmacy (N=30). RESULTS: Retail cash prices varied for all antipsychotic medications, with significant differences in price by pharmacy type. Price variation across all pharmacy types was lowest for haloperidol ($20-$102.99) and highest for aripiprazole ($29.99-$1,345.00). Pairwise comparisons showed that chain pharmacies had higher prices, compared with independent pharmacies, for all medications except haloperidol. Overall, chain pharmacies had the highest prices, with prices at grocery store pharmacies averaging $180 lower than chain pharmacies, and independent pharmacies averaging $415 lower than chain pharmacies. CONCLUSIONS: This report is the first on pharmacy-level variability in the costs of generic antipsychotic treatment options for schizophrenia. Appreciable differences were found in the costs of generic antipsychotics. Understanding variability in antipsychotic pricing may be important for providers serving uninsured patients.

A Multilevel Diabetes and CVD Risk Reduction Intervention in African American Churches: Project Faith Influencing Transformation (FIT) Feasibility and Outcomes.

Wide-reaching health promotion interventions are needed in influential, accessible community settings to address African American (AA) diabetes and CVD disparities. Most AAs are overweight/obese, which is a primary clinical risk factor for diabetes/CVD. Using a faith-community-engaged approach, this study examined feasibility and outcomes of Project Faith Influencing Transformation (FIT), a diabetes/CVD screening, prevention, and linkage to care pilot intervention to increase weight loss in AA church-populations at 8 months. Six churches were matched and randomized to multilevel FIT intervention or standard education control arms. Key multilevel religiously tailored FIT intervention components included: (a) individual self-help materials (e.g., risk checklists, pledge cards); (b) YMCA-facilitated weekly group Diabetes Prevention Program (DPP) weight loss classes; (c) church service activities (e.g., sermons, responsive readings); and (d) church-community text/voice messages to promote healthy eating and physical activity. Health screenings (e.g., weight, blood pressure, blood glucose) were held during church services to identify participants with diabetes/CVD risks and refer them to their church's DPP class and linkage to care services. Participants (N = 352 church members and community members using churches' outreach ministries) were primarily female (67%) and overweight/obese (87%). Overall, FIT intervention participants were significantly more likely to achieve a > 5 lb weight loss (OR = 1.6; CI = 1.24, 2.01) than controls. Odds of intervention FIT-DPP participants achieving a > 5 lb weight loss were 3.6 times more than controls (p < .07). Exposure to sermons, text/email messages, brochures, commitment cards, and posters was significantly related to > 5 lb. weight loss. AA churches can feasibly assist in increasing reach and impact of diabetes/CVD risk reduction interventions with intensive weight loss components among at risk AA church-populations.

Associations between the vaginal microbiome and Candida colonization in women of reproductive age.

BACKGROUND: The composition of bacteria within the vaginal microbiome has garnered a lot of recent attention and has been associated with reproductive health and disease. Despite the common occurrence of yeast (primarily Candida) within the vaginal microbiome, there is still an incomplete picture of relationships between yeast and bacteria (especially lactobacilli), as well as how such associations are governed. Such relationships could be important to a more holistic understanding of the vaginal microbiome and its connection to reproductive health. OBJECTIVE: The objective of the study was to perform molecular characterization of clinical specimens to define associations between vaginal bacteria (especially Lactobacillus species) and Candida colonization. In vitro studies were conducted to test the 2 most common dominant Lactobacillus species (Lactobacillus crispatus and Lactobacillus iners) in their ability to inhibit Candida growth and to examine the basis for such inhibition. STUDY DESIGN: A nested cross-sectional study of reproductive-age women from the Contraceptive CHOICE Project was conducted. Vaginal swabs from 299 women were selected to balance race and bacterial vaginosis status, resulting in a similar representation of black and white women in each of the 3 Nugent score categories (normal [0-3], intermediate [4-6], and bacterial vaginosis [7-10]). Sequencing of the 16S ribosomal gene (V4 region) was used to determine the dominant Lactobacillus species present (primarily Lactobacillus iners and Lactobacillus crispatus), defined as >50% of the community. Subjects without dominance by a single Lactobacillus species were classified as Diverse. A Candida-specific quantitative polymerase chain reaction targeting the internally transcribed spacer 1 was validated using vaginal samples collected from a second cohort of women and used to assess Candida colonization. Two hundred fifty-five nonpregnant women with sufficient bacterial biomass for analysis were included in the final analysis. Generalized linear models were used to evaluate associations between Lactobacillus dominance, sociodemographic and risk characteristics, and vaginal Candida colonization. In separate in vitro studies, the potential of cell-free supernatants from Lactobacillus crispatus and Lactobacillus iners cultures to inhibit Candida growth was evaluated. RESULTS: Forty-two women (16%) were vaginally colonized with Candida. Microbiomes characterized as Diverse (38%), Lactobacillus iners-dominant (39%), and Lactobacillus crispatus-dominant (20%) were the most common. The microbiome, race, and Candida colonization co-varied with a higher prevalence of Candida among black women and Lactobacillus iners-dominant communities compared with white women and Lactobacillus crispatus-dominant communities. Lactobacillus iners-dominant communities were more likely to harbor Candida than Lactobacillus crispatus-dominant communities (odds ratio, 2.85, 95% confidence interval, 1.03-7.21; Fisher exact test, P = .048). In vitro, Lactobacillus crispatus produced greater concentrations of lactic acid and exhibited significantly more pH-dependent growth inhibition of Candida albicans, suggesting a potential mechanism for the clinical observations. CONCLUSION: In nonpregnant women, Lactobacillus iners-dominant communities were significantly more likely to harbor Candida than Lactobacillus crispatus-dominant communities, suggesting that Lactobacillus species have different relationships with Candida. In vitro experiments indicate that Lactobacillus crispatus may impede Candida colonization more effectively than Lactobacillus iners through a greater production of lactic acid.

Risk factors for cervical ectopic pregnancy.

OBJECTIVE: To evaluate risk factors for cervical ectopic pregnancies. METHODS: Retrospective, quasi-experimental case-control study of cervical ectopic pregnancy (CEP) cases from 2000-2013. Two groups were selected as controls, patients with tubal ectopic (TEP) and intrauterine pregnancies (IUP) without a history of TEP, matched by year of pregnancy and randomly sampled in a 1:3 case-control ratio per each study group. RESULTS: 21 cases were identified and 126 controls included, 63 TEP and IUP each. A binary logistic regression model was used to analyze whether statistically significant preceding factors from a bivariate analysis could predict CEP. Compared to patients with IUP, CEP patients had a higher history of elective abortions, D&C and cervical excisional procedures, with a high effect size (>0.7). Compared to patients with TEP, CEP patients had a higher history of D&C and cervical excisional procedures, with a high effect size (>.7). The risk of CEP was significantly higher with a prior history of D&C compared to an IUP (aOR 1.4; 95% CI, 1.1-9.1; p=0.04) and a TEP (aOR 6.1; 95% CI, 1.8-21.2; p=0.04). CONCLUSION: D&C is a strong risk factor for CEP when compared to pregnancies in other locations. These findings confirm previous associations described in case series.

Association between obesity and bacterial vaginosis as assessed by Nugent score.

BACKGROUND: Bacterial vaginosis is 1 of the most common vaginal conditions in the United States. Recent studies have suggested that obese women have an abnormal microbiota reminiscent of bacterial vaginosis; however, few studies have investigated the prevalence of bacterial vaginosis in overweight and obese populations. Moreover, despite the increased prevalence of obesity and bacterial vaginosis in black women, it is not known whether racial disparities exist in the relationship between obesity and bacterial vaginosis. OBJECTIVE: The objective of this study was to examine the relationship between body mass index and bacterial vaginosis as determined by Nugent score and to determine the influence of race in this context. STUDY DESIGN: We performed a cross-sectional study using patient data and vaginal smears from 5918 participants of the Contraceptive CHOICE Project. Gram-stained vaginal smears were scored with the Nugent method and categorized as bacterial vaginosis-negative (Nugent score, 0-3), bacterial vaginosis-intermediate (Nugent score, 4-6), or bacterial vaginosis-positive (Nugent score, 7-10). Body mass index was determined with Centers for Disease Control and Prevention guidelines, and obese individuals were categorized as class I, II, or III obese based on National Institutes of Health and World Health Organization body mass index parameters. Linear regression was used to model mean differences in Nugent scores; Poisson regression with robust error variance was used to model prevalence of bacterial vaginosis. RESULTS: In our cohort, 50.7% of participants were black; 41.5% were white, and 5.1% were of Hispanic ethnicity; the average age of 25.3 years old. Overall, 28.1% of participants were bacterial vaginosis-positive. Bacterial vaginosis was prevalent in 21.3% of lean, 30.4% of overweight, and 34.5% of obese women (P<.001). The distribution of bacterial vaginosis-intermediate individuals was similar across all body mass index categories. Compared with the scores of lean women, Nugent scores were highest among overweight and obese class I women (adjusted mean difference: overweight women, 0.33 [95% confidence interval, 0.14-0.51] and obese women, 0.51 [95% confidence interval, 0.29-0.72]). Consistent with this, overweight and obese women had a higher frequency of bacterial vaginosis compared with lean women, even after adjustment for variables that included race. Among white women, the prevalence of bacterial vaginosis was higher for overweight and class I and class II/III obese white women compared with lean white women, which is a phenomenon not observed among black women and suggests an effect modification. CONCLUSION: Overweight and obese women have higher Nugent scores and a greater occurrence of bacterial vaginosis compared with lean women. Black women have a greater prevalence of bacterial vaginosis independent of their body mass index compared with white women.

Outcomes in subsequent pregnancies after wedge resection for interstitial ectopic pregnancy: a retrospective cohort study.

OBJECTIVE: The objective of this study is to evaluate pregnancy outcomes in patients with a history of wedge resection for interstitial ectopic pregnancy (WRIEP). METHODS: Retrospective cohort study of pregnancies with a history of WRIEP from 2000 to 2013 at two inner city hospitals in Detroit, MI. Pregnant-matched controls (1:3) were selected and included patients with history of surgically treated tubal ectopic pregnancy and delivered patients without history of ectopic pregnancy. Pregnancy outcomes, including a composite, were compared among the groups. RESULTS: Eighty-three cases of interstitial pregnancy were identified. Sixty-three (75.9%) underwent WRIEP from which 19 (30.2%) had a subsequent pregnancy and 11 (57.9%) carried it ≥20 weeks. No difference in subsequent pregnancy outcomes including the composite was found among patients with prior WRIEP and patients with history of surgically treated tubal ectopic pregnancy except for a longer interpregnancy interval. Compared with delivered patients without a history of ectopic pregnancy, no difference in late obstetric outcomes was found including the composite, gestational age at delivery in weeks (38.2 versus 38.1, p = .955), preterm delivery rate (30% versus 21%, p = .674), and proportion of term vaginal (40% versus 52%, p = .721) or cesarean deliveries (60% versus 30%, p = .137). The most common indication for cesarean among patients with a history of WRIEP was a history of such (5/6, 83.3%) and there were no cases of abnormal placentation. CONCLUSION: Findings suggest that a history of WRIEP is not associated with increased risk of adverse pregnancy outcomes.

Feasibility and Outcomes of an HIV Testing Intervention in African American Churches.

The updated National HIV/AIDS Strategy recommends widespread HIV education and testing and calls the faith community to assist in these efforts. Yet, limited information exist on church-based HIV testing interventions. This study examined feasibility and assessed HIV testing outcomes of Taking It to the Pews (TIPS), a multilevel HIV education and testing intervention. Four African American churches were matched and randomized to TIPS or a standard-information control arm. Intervention churches delivered the religiously-tailored TIPS Tool Kit, which included educational materials to individuals and ministry groups; pastoral activities (e.g., sermons preached, receipt of HIV testing role-modeled), responsive readings, and church bulletin inserts in church services; and HIV testing during church services and church outreach events. All churches delivered 2-3 tools/month and coordinated 3 HIV testing events. At 12 months, significant increases in receipt of HIV testing (59% vs. 42%, p = 0.008), and particularly church-based testing (54% vs. 15%, p < 0.001), relative to controls were found. TIPS has great potential to increase reach, feasibility, and impact of HIV testing in African American churches.

Differences in Contraceptive Discontinuation Among Black and White Women: Evidence from the Contraceptive CHOICE Project.

OBJECTIVE: We sought to evaluate whether differences in rates of contraceptive discontinuation exist among black and white women receiving contraceptive counseling and no-cost contraception among users of long-acting reversible contraceptive (LARC; intrauterine devices or subdermal implant) and non-LARC (oral contraceptive pills, contraceptive vaginal ring, patch, or injection) methods. MATERIALS AND METHODS: We analyzed data from a prospective cohort study of 7546 non-Hispanic black and white women who participated in the Contraceptive CHOICE Project. Among women who initiated their method within 12 weeks of enrollment, discontinuation was defined as any break in use longer than 1 month. Using Cox proportional hazards regression analysis, we estimated discontinuation stratified by use of LARC methods. RESULTS: There were no statistically significant differences in contraceptive discontinuation between black and white women at 12, 24, or 36 months among both LARC [12-month adjusted hazard ratio (HRadj-12M) 1.01 (95% confidence interval or 95% CI 0.86-1.18); HRadj-24M 1.10 (95% CI 0.97-1.24); and HRadj-36M 1.10 (95% CI 0.98-1.23)] and non-LARC users [HRadj-12M 1.08 (95% CI 0.92, 1.26); HRadj-24M 1.07 (95% CI 0.94, 1.23); and HRadj-36M 1.08 (95% CI 0.95, 1.23)] adjusting for confounders. Secondary analyses found no significant differences in discontinuation of LARC and non-LARC methods among black and white women at highest risk of pregnancy or those receiving public assistance at baseline. CONCLUSIONS: At 12, 24, and 36 months there were no differences in contraceptive discontinuation of both LARC methods and non-LARC methods when comparing white and black women.

Ethnic/racial differences in gastrointestinal symptoms and diagnosis associated with the risk of Helicobacter pylori infection in the US.

BACKGROUND: In the US, neither the prevalence nor the gastrointestinal (GI) diagnosis/symptoms associated with Helicobacter pylori (HP) have been examined in different racial/ethnic groups. AIM: To determine the racial/ethnic differences in HP infection associated with GI diagnoses/symptoms using the Cerner Health Facts® database. METHODS: This cross-sectional study collected data during the period of 2000-2015 from the following ethnic/racial groups: 8,236,317 white, 2,085,389 black, 426,622 Hispanic, 293,156 Asian Pacific/Islander (APIs), and 89,179 Native American/Alaskan Native (NA/AN) patients aged 21-65 years old; the data were then analyzed. The primary dependent variable was a diagnosis of HP (ICD-9-Clinical Modification/ICD-10 classification). SAS version 9.4 was used for the statistical analysis. The statistical analysis was performed on 11,130,663 patients with GI symptoms, and of these, 152,086 patients were positive for the infection. RESULTS: Hispanics and NA/ANs had the highest prevalence of HP associated with upper GI symptoms/diagnosis. Nevertheless, blacks and APIs presented the highest relative risk (RR) of HP associated with dyspepsia (RR [95% CI] =11.2 [10.7-11.9] and 14.2 [12.8-15.6]), peptic ulcer (RR =13.8 [13.3-14.5] and 10.7 [9.3-12.3]), and atrophic gastritis (RR =9 [8.5-9.6] and 7.4 [6.4-8.5]), respectively. In all racial/ethnic groups, HP was also associated with inflammatory bowel diseases, liver diseases, and celiac diseases. CONCLUSION: Black and API populations had the highest risk of HP associated with upper GI symptoms/diagnosis. Black patients also had the highest risk for HP associated with GI cancer.

Effects of intrauterine contraception on the vaginal microbiota.

OBJECTIVES: There have been conflicting reports of altered vaginal microbiota and infection susceptibility associated with contraception use. The objectives of this study were to determine if intrauterine contraception altered the vaginal microbiota and to compare the effects of a copper intrauterine device (Cu-IUD) and a levonorgestrel intrauterine system (LNG-IUS) on the vaginal microbiota. STUDY DESIGN: DNA was isolated from the vaginal swab samples of 76 women using Cu-IUD (n=36) or LNG-IUS (n=40) collected prior to insertion of intrauterine contraception (baseline) and at 6 months. A third swab from approximately 12 months following insertion was available for 69 (Cu-IUD, n=33; LNG-IUS, n=36) of these women. The V4 region of the bacterial 16S rRNA-encoding gene was amplified from the vaginal swab DNA and sequenced. The 16S rRNA gene sequences were processed and analyzed using the software package mothur to compare the structure and dynamics of the vaginal bacterial communities. RESULTS: The vaginal microbiota from individuals in this study clustered into 3 major vaginal bacterial community types: one dominated by Lactobacillus iners, one dominated by Lactobacillus crispatus and one community type that was not dominated by a single Lactobacillus species. Changes in the vaginal bacterial community composition were not associated with the use of Cu-IUD or LNG-IUS. Additionally, we did not observe a clear difference in vaginal microbiota stability with Cu-IUD versus LNG-IUS use. CONCLUSIONS: Although the vaginal microbiota can be highly dynamic, alterations in the community associated with the use of intrauterine contraception (Cu-IUD or LNG-IUS) were not detected over 12 months. IMPLICATIONS: We found no evidence that intrauterine contraception (Cu-IUD or LNG-IUS) altered the vaginal microbiota composition. Therefore, the use of intrauterine contraception is unlikely to shift the composition of the vaginal microbiota such that infection susceptibility is altered.
