A survey of women obtaining emergency contraception: are they interested in using the copper IUD?

BACKGROUND This study aims to determine if women presenting for emergency contraception (EC) at family planning clinics may be interested in using the copper intrauterine device (IUD) for EC. STUDY DESIGN This convenience sample survey was offered to women who presented for EC at four participating clinics in urban Utah. Anonymous written questionnaires were distributed. The outcome variable of interest was interest in using the copper IUD for EC. RESULTS Of survey respondents, 320 (34.0%) of 941 said they would be interested in an EC method that was long term, highly effective and reversible. Interested women were not significantly different from noninterested women in relation to age, marital status, education, household income, gravidity, previous abortions, previous sexually transmitted infections (STIs) or relationship status. One hundred twenty women (37.5% of those interested or 12.8% of all those surveyed) would wait an hour, undergo a pelvic exam to get the method and would still want the method knowing it was an IUD. However, only 12.3% of these women could also pay

Evaluation of the use of anti-TNF-α in an LPS-induced murine model

350 or more for the device. Multivariable regression found the following predictors of interest in the IUD among EC users: non-Hispanic minorities (OR=2.12, 95% CI=1.14-3.93), desire to never be pregnant in the future (OR=2.87, 95% CI=1.38-5.66) and interest in adoption (OR=1.96, 95% CI=1.00-5.73) or abortion (OR=2.68, 95% CI=1.24-4.14) if pregnant when presenting for EC. CONCLUSION While one third of EC users surveyed at family planning clinics were interested in a long-term, highly effective method of contraception, only a small portion of all EC users may be interested in the copper IUD for EC. Cost is a potential barrier.

Risk reduction behaviors and provider communication following genetic counseling and BRCA1 mutation testing in an African American kindred.

OBJECTIVE Tumor necrosis factor alpha (TNF-alpha) may play a critical role in inflammatory-mediated preterm labor. Medications blocking the activity of TNF-alpha have been shown to be effective in the treatment of conditions such as rheumatoid arthritis; however, the use of these medications for an event like preterm birth or fetal death is unknown. We hypothesized that treatment with anti-TNF-alpha may decrease the rate of fetal death and preterm birth in a LPS-induced murine model. METHODS Pregnant C57BL/6J mice received intraperitoneal (IP) injections of either vehicle or 2mg anti-TNF-alpha. After 24h, 10 microg of LPS was administered IP. Mice were sacrificed 24h later and outcomes between groups were assessed. A second set of experiments utilizing RT-PCR was performed to determine the influence of anti-TNF-alpha on production of inflammatory cytokines in response to LPS. RESULTS There were 72 resultant pups in the LPS+saline group, and 91 in the group receiving LPS+anti-TNF-alpha. Pretreatment with anti-TNF-alpha reduced the rate of fetal death and preterm birth after LPS administration (p<0.01). Expression of IL-6, IL-1beta, TLR-2, CD14 and COX-1 were found to be significantly reduced in mice treated with anti-TNF-alpha and LPS compared to LPS alone. CONCLUSION The use of anti-TNF-alpha decreased fetal deaths and preterm deliveries in an LPS-induced model of preterm birth. In addition, there were critical gene expression alterations in the group receiving anti-TNF-alpha. Further evaluation of TNF-alpha blockade as a potential treatment for preterm labor is warranted.

Colorectal Cancer Surveillance Behaviors Among Members of Typical and Attenuated FAP Families

Little is known about the impact of cancer genetic counseling and testing on health behaviors in racial and ethnic subgroups. This prospective observational study examined use of risk reduction strategies following BRCA1 counseling and testing. Participants were female members of an African American kindred who received genetic education, counseling and testing (n = 40) and completed a 1-year follow-up interview. Mutation carriers were more likely to opt for breast (100%, 7/7) and ovarian (25%; 1 of 4) cancer surveillance than prophylactic surgery. Following genetic counseling, 71% (5/7) of the BRCA1 carriers who opted for surveillance reported having a mammogram within the year following receipt of their genetic test results. Ovarian cancer screening among mutation carriers increased from 0% at baseline to 25% (one of four) at 1 year. Compared to noncarriers (23%, 7/30), carriers (70%, 7/10) were more likely to discuss their BRCA1 test results with their primary health care providers. Surveillance for breast cancer was preferred to prophylactic surgery and chemoprevention as a way to reduce risk for these cancers. Our data indicate that patient-provider communication about BRCA1 test results is suboptimal.

Crosslinked hydrogels for tympanic membrane repair

OBJECTIVES:Although enhanced colorectal surveillance is recommended for members of familial adenomatous polyposis (FAP) families, little is known about individual-level adherence behavior. This study examined factors associated with recent use of colorectal cancer (CRC) surveillance among FAP patients and their at-risk relatives.METHODS:This cross-sectional study conducted a computer-assisted telephone survey among 150 members of 71 extended families with classic (FAP) or attenuated adenomatous polyposis (AFAP). Participants were enrolled in a university-based hereditary CRC registry or were first-degree relatives of enrollees. Both qualitative and quantitative data were collected and analyzed.RESULTS:Surveillance behavior varied by disease status. Fifty-four percent of 71 participants with a personal history of FAP and 42% of 79 at-risk relatives reported recent use of CRC surveillance recommendations. In multiple logistic regression analysis, lack of patient recall of provider recommendation for an endoscopic examination of the colon (OR 4.8, 95% CI 1.8–13.1), lack of health insurance or no reimbursement for CRC surveillance (OR 3.6, 95% CI 1.2–10.5), and/or the belief that their relative risk of CRC is not increased (OR 3.1, 95% CI 1.2–7.1) were independently associated with not having had a recent colonoscopy or sigmoidoscopy.CONCLUSIONS:Despite the known benefits of CRC surveillance, a substantial proportion of FAP family members did not have a recent colonoscopy or endoscopy. Interventions targeted at both clinicians and patients are needed to improve surveillance behavior. These data are also important in designing decision support tools to assist clinicians in identifying and managing high-risk patients.

Effect of grand multiparity on intrapartum and newborn complications in young women

PROBLEM: To provide a less expensive and more convenient protocol for the treatment of tympanic membrane perforations (TMPs). METHODS: Several materials were prepared and compared for TMP repair including Carbylan-SX, Gelatin-DTPH-PEGDA (GX), Carbylan-S/Gelatin-DTPH (Carbylan-GSX) (injectable and sponge), Gelfoam, Epifilm, and crosslinked thiolated chondroitin sulfate (CS-DTPH-PEGDA [CS-SX]). Hartley pigmented guinea pigs (Elm Hill) underwent bilateral myringotomy with 1 ear left as a control and the other treated with one of the previously mentioned materials. RESULTS: Carbylan-GSX (injectable and sponge), Gelfoam with saline, and CS-SX had the shortest time for TMP closure. Epifilm, Carbylan, and gelatin preparations resulted in closure rates similar to controls. CS-SX showed a marked inflammatory reaction compared with controls and other materials based on neutrophil, lymphocyte, epitheloid counts, and degree of fibrosis. CONCLUSIONS: This study shows the validity of Carbylan-GSX compared with Gelfoam as a material to promote TMP closure in an acute TMP guinea pig model.

Cross-linked hydrogels for middle ear packing.

Objective: To examine the effect of high parity on complications in young women, aged 18–34 years. Methods: Seven years of Utah birth certificate data were reviewed (1995–2001). Young nulliparas and primiparas were compared with young grand and great grand multi-paras by using logistic regression. Young grand multiparas were compared with older grand multiparas. Results: Young grand multiparas were more likely to have a preterm delivery and less likely to experience fetal distress, instrumented delivery, cesarean delivery, and any intrapartum complication than young nulliparas or primiparas. Young grand multiparas were less likely to experience many complications than their older counterparts. Conclusion: Among young women, grand and great grand multiparity does not increase the risk for most intrapartum and newborn complications. Young grand and great grand multiparas are at significantly decreased risk for many complications when compared with young women of lower parity and older grand and great grand multiparas. Level of Evidence: II-2

Acceptance of genetic testing for hereditary breast ovarian cancer among study enrollees from an African American kindred.

Objective: To develop an ideal supportive packing material for ossiculoplasty, tympanoplasty, or other otologic procedures. Materials and Methods: Several materials, namely, Carbylan-SX (P-C; Sentrx Surgical, Inc., Salt Lake City, UT), Gelfoam (P-GF; Pharmacia & Upjohn, Kalamazoo, MI), and Merogel (P-MG; Medtronics, Inc., Minneapolis, MN), were prepared and then placed into a Hartley guinea pigs (Elm Hill, Chelmsford, MA) middle ear cavities through a large myringotomy incision. The contralateral ear underwent a large myringotomy without packing material being placed. Preoperative and posteroperative auditory brainstem response studies were performed using Intelligent Hearing system software. The animals were examined weekly. Two weeks after packing placement, the animals were killed, and the temporal bones were harvested. Whole temporal bone sectioning was performed to analyze the presence of implant, surrounding inflammation, presence of osteoneogenesis and fibrosis, or adhesions. Results: All the materials, except the P-MG, were easy to place into the middle ear cavity. The P-MG contains woven strands that are difficult to trim into the small sizes needed for placement. The P-MG group had a smaller average amount of implant present compared with the other groups at 2 weeks. The degree of osteoneogenesis was similar among the P-GF, P-C, and P-MG groups. The P-MG and P-C groups contained the lowest amount of fibrosis between the implant and surrounding middle ear structures. Conclusion: This study demonstrates promising results with P-C as a potential supportive packing material for otologic procedures. P-C compares favorably with P-MG and P-GF in a guinea pig model with respect to ease of placement and amount of fibrosis.

Emergency contraception with a copper IUD or oral levonorgestrel: an observational study of 1-year pregnancy rates.

Clinical availability of genetic testing for cancer predisposition genes is generating a major challenge for U.S. health care systems to provide relevant genetic services to underserved populations. Here we present rates of study enrollment and utilization of genetic testing in a research study on BRCA1 testing acceptance in one large kindred. We also present data on baseline access to genetic information as well as enabling and obstructing factors to study enrollment. The study population included female and male members of an African American kindred based in the rural southern United States with an identified BRCA1 mutation. A combination of quantitative and qualitative data were collected and analyzed. Of the 161 living, eligible, and locatable kindred members, 105 (65%) enrolled in the study. Family, personal, and educational motivations were the most commonly endorsed reasons for study participation. The most commonly cited reasons for refusal to participate in the study were: lack of interest, time constraints, and negative experiences with prior participation in genetic research. Eighty three percent of the participants underwent BRCA1 testing. In multiple logistic regression analysis, age 40–49 (odds ratio (OR) = 6.9; 95% confidence interval (CI) = 1.2–39.5), increased perceived risk of being a BRCA1 mutation carrier (OR = 4.1; 95% CI = 1.1–14.6), and high cancer genetics knowledge levels (OR = 1.5; 95% CI = 1.1–2.3) were associated with BRCA1 testing acceptance. The results of this study indicate that cognitive and demographic factors may influence genetic research participation and genetic testing decisions among African Americans who are at increased risk of carrying a deleterious BRCA1 mutation.

Risk factors for recurrent preterm birth in multiparous Utah women: a historical cohort study

OBJECTIVE We investigated the 1-year pregnancy rates for emergency contraception (EC) users who selected the copper T380 intrauterine device (IUD) or oral levonorgestrel (LNG) for EC. STUDY DESIGN This prospective study followed women for 1 year after choosing either the copper T380 IUD or oral LNG for EC. The study was powered to detect a 6% difference in pregnancy rates within the year after presenting for EC. RESULTS Of the 542 women who presented for EC, agreed to participate in the trial and met the inclusion criteria, 215 (40%) chose the copper IUD and 327 (60%) chose oral LNG. In the IUD group, 127 (59%) were nulligravid. IUD insertion failed in 42 women (19%). The 1-year follow-up rate was 443/542 (82%); 64% of IUD users contacted at 1 year still had their IUDs in place. The 1-year cumulative pregnancy rate in women choosing the IUD was 6.5% vs. 12.2% in those choosing oral LNG [hazard ratio (HR) 0.53, 95% confidence interval (CI): 0.29-0.97, p=.041]. By type of EC method actually received, corresponding values were 5.2% for copper IUD users vs. 12.3% for oral LNG users (HR 0.42, 95% CI: 0.20-0.85, p=.017). A multivariable logistic regression model controlling for demographic variables demonstrates that women who chose the IUD for EC had fewer pregnancies in the following year than those who chose oral LNG (HR 0.50, 95% CI: 0.26-0.96, p=.037). CONCLUSION One year after presenting for EC, women choosing the copper IUD for EC were half as likely to have a pregnancy compared to those choosing oral LNG. IMPLICATIONS Compared to EC users who choose oral levonorgestrel, those who select the copper IUD have lower rates of pregnancy in the next year. Greater use of the copper IUD for EC may lower rates of unintended pregnancy in high-risk women.
