OBJECTIVE: To examine the acceptability of five nonoxynol-9 (N-9) spermicides. METHODS: We analyzed data from a randomized trial of five products, including three gels containing different amounts of N-9 per dose, a film and a suppository. In the trial, 1536 participants were asked to use the assigned spermicide for 7 months and to complete questionnaires 4 weeks after admission and at discontinuation. RESULTS: Overall, 43% of participants liked their spermicide "very much." This proportion was higher in the three gel groups than in the suppository and film groups. Difficulty with insertion, messiness and discontent with timing of insertion were common complaints in all groups. After adjustment for selected baseline factors, acceptability on the first questionnaire was not related to duration or consistency of subsequent spermicide use or to subsequent time to pregnancy. CONCLUSIONS: In this study, all five spermicides were considered acceptable by most users. Acceptability did not appear to influence spermicide use or pregnancy risk.  相似文献

OBJECTIVE: It is recognized that pregnant teenagers have higher levels of psychological symptomatology compared to older pregnant women. However, there are limited data on fathers in the setting of teenage pregnancy. The aim of this study was to compare levels of psychological symptomatology in fathers in the setting of teenage as compared to non-teenage pregnancy. METHOD: A cross-sectional cohort study was undertaken. Data from interviews with consecutive fathers in the setting of teenage (Teenage) and non-teenage (Control) pregnancy were compared during the antenatal period. Subjects were interviewed to obtain information covering demographic and family information, the Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire-28 (GHQ-28). RESULTS: Significantly more fathers in the setting of teenage pregnancy met the case criteria for HADS-A and HADS-D subscales compared to older fathers. They had significantly higher GHQ-28 totals and all subscale scores and were more likely predictive of a young age of death compared to older fathers. However, formal contact with psychiatric services was similar between groups. Interestingly, 14% of fathers in the setting of teenage pregnancy reported losing their own father as a child. In multivariate analysis, a high HADS score was significantly associated with younger age of onset of fatherhood and exposure to domestic violence as a child, whereas having their own father alive was significantly protective against a high HADS score. CONCLUSION: Fathers, in the setting of teenage pregnancy, have unrecognized psychological symptomatology and require services along with teenage mothers.  相似文献

A total of 45 primary head and neck squamous cell carcinomas were analysed by comparative genomic hybridisation to identify regions of chromosomal deletion and gain. Multiple regions of copy number aberration were identified including gains affecting chromosomes 3q, 8q, 5p, 7q, 12p and 11q and deletion of material from chromosomes 3p, 11q, 4p, 5q, 8p, 10q, 13q and 21. Kaplan-Meier survival analysis revealed significant correlations between gain of 3q25-27 and deletion of 22q with reduced disease-specific survival. In addition, gain of 17q and 20q, deletion of 19p and 22q and amplification of 11q13 were significantly associated with reduced disease-free survival. A Cox proportional hazards regression model identified deletion of 22q as an independent prognostic marker. The data presented here provide further evidence that the creation of a genetically based tumour classification system will soon be possible, complementing current histopathological characterisation.  相似文献

Objective: This study was performed to test the hypothesis that an increased prevalence of activated protein C (APC) resistance in women with polycystic ovary syndrome (PCOS) puts them at increased risk of miscarriage and thrombosis.

Design: Case control study.

Setting: A district general hospital in the United Kingdom.

Patient(s): Forty-one women with PCOS and 25 controls.

Intervention(s): Clinical histories, ultrasound scans, and venepunctures.

Main Outcome Measure(s): Diagnosis of PCOS or control, clinical histories, APC resistance according to an activated partial thromboplastin time–based assay.

Result(s): There was no significant difference in the proportion of women with APC resistance in both groups (three women in the PCOS group [7%] vs. one woman in the control group [4%]). The prevalence of APC resistance in the entire study population was 6.5%. In the PCOS group, 29% (12/41) gave a positive family history of thrombosis compared with 8% (2/25) in the control group. None of the women with a positive family history of thrombosis had abnormal antithrombin 111, protein C, or protein S levels.

Conclusion(s): This study suggests that women with PCOS may have the same prevalence of APC resistance as the background population and that APC resistance may not put them at a higher risk of thrombosis or miscarriage compared with the case of the general population.  相似文献

OBJECTIVE: To assess the impact that education through participation in a depression screening program has on mental health literacy and help seeking behavior in perinatal women. METHODS: Responses to a hypothetical case of depression, help seeking behavior, and screening levels for risk of depression using the Edinburgh Postnatal Depression Scale were compared between two groups of postnatal women; one group who had participated in a screening program and the other who had not. Those who participated in the screening program were also asked to evaluate the educational material they had received. RESULTS: A total of 1309 women, broadly representative of postnatal women, answered one or more questionnaires. Those who had participated in the screening program were better able to recognize depression in a hypothetical case, and also assess their own mental state more appropriately. Those women who had been part of the program and did not score high on the EPDS were less likely to seek help, were more satisfied when they did and tended to benefit more from the educational booklet. CONCLUSIONS: Participation in a screening program with educational material had significant benefits for mental health literacy and the health service use for perinatal women at risk for depression.  相似文献
