Objective: To determine whether change in paternity changes recurrence risk of hyperemesis gravidarum (HG). Study design: Survey data on recurrence of HG was compared between cases who had a paternity change between pregnancies and cases who did not. Results: The percentage of HG pregnancies in women with the same partner for all pregnancies was not significantly different from the percentage of HG pregnancies in women who changed partners for at least one pregnancy (78% vs 71%, p?>?0.05). Participants who did and did not change partners between their first and second pregnancies, were asked to rate their first and second pregnancy in regards to symptoms of HG. Neither the ratings nor the change in rating between pregnancies was significantly different between the two groups. Conclusion: Women reported HG in over 70% of their pregnancies regardless of a paternity change. Paternal genes expressed through the fetus do not have a significant effect on incidence or recurrence of HG. This study supports a strong maternal genetic factor involved in HG. However, because the recurrence risk is not 100%, other factors play a role. Identification of the predisposing gene(s) and other factors will determine the cause of this poorly understood complication of pregnancy.  相似文献

OBJECTIVE: To establish the role of clinical chorioamnionitis as an independent risk factor for recurrence in a subsequent pregnancy. METHOD: This was a historical cohort study of pregnant women who had their first and second deliveries at our institution between January 1988 and May 2005. The index pregnancy was restricted to those who delivered vaginally. Data were collected from a continuously updated obstetric database and included demographic and labor characteristics and neonatal outcomes. Chorioamnionitis was diagnosed clinically. RESULTS: The study population consisted of 23,397 women. During the index pregnancy, 10% of women developed chorioamnionitis. This group was significantly different from the rest of the cohort in terms of age, ethnicity, length of labor, epidural analgesia, use of internal monitors, and incidence of prolonged rupture of membranes. In the second pregnancy, 6% of those women again developed chorioamnionitis compared with 2% of women who did not have chorioamnionitis in the first pregnancy (odds ratio 2.93, 95% confidence interval 2.40-3.57). After adjusting for the above confounders, the increased risk of recurrence persisted (odds ratio 1.85, 95% confidence interval 1.49-2.30). CONCLUSION: Women delivering vaginally who were diagnosed with chorioamnionitis during their first pregnancy are at increased risk for chorioamnionitis in a subsequent pregnancy. This supports the concept that there may be a predisposition to chorioamnionitis that should be further investigated. LEVEL OF EVIDENCE: II-2.  相似文献

OBJECTIVE: Parity and hormonal contraceptives modify the risk of reproductive cancers and cardiovascular disease. However, clinicians may not obtain reproductive histories from patients who self-identify as lesbian. We report lifetime pregnancy-related outcomes and hormonal contraception for 392 women who reported sexual activity with another woman in the preceding year. STUDY DESIGN: Among self-referred volunteers, previous pregnancy, pregnancy outcome, contraceptive use, and sexual identity were assessed with self-administered questionnaire. RESULTS: One in 4 subjects had been pregnant, and more than 50% of the women had used oral contraceptives (mean duration, 40 months). Sixteen percent of all subjects and 63% of those who had been pregnant previously reported having 1 or more induced abortions. The most common pregnancy outcome for women younger than 25 years was induced abortion (59% of pregnancies). Identifying as "lesbian" or "bisexual" predicted neither the duration of oral contraceptive use nor a report of induced abortion. CONCLUSION: Previous pregnancy, induced abortion, and hormonal contraceptive use are common among women who report sex with women, regardless of self-identification as lesbian.  相似文献

OBJECTIVE: To confirm that leukocyte immunotherapy stimulates the production of cardiolipin antibodies and to relate changes to pregnancy outcome. PATIENTS: Fifty patients with idiopathic recurrent abortion were studied. Thirty-six patients received injections of their partners' leukocytes; 14, injected with their own cells, served as controls. DESIGN: Cardiolipin antibodies were measured a month before and after leukocyte immunization. Patients who became pregnant were immunized a second time in early pregnancy, and cardiolipin antibodies were again measured a month later. RESULTS: Thirty-six patients immunized with their partners' leukocytes showed no appreciable change in cardiolipin antibody levels a month after vaccination. Twenty-nine of them subsequently became pregnant and were immunized again in early pregnancy: again, no change in cardiolipin antibody level was observed. There was no difference between the minority who aborted again and the majority who subsequently had successful pregnancies nor between those who responded to immunotherapy by producing cytotoxic antilymphocyte antibodies and those who did not. CONCLUSION: Leukocyte immunotherapy does not stimulate cardiolipin antibody production in women with normal pretreatment levels of the autoantibody.  相似文献

A random sample of women in the Midwestern United States was studied in order to provide a fuller picture of the ways in which US women responded to subfecundity. Using a biomedical definition of infertility, we examined women who did not conceive within 12 months of unprotected intercourse whether they were trying to get pregnant or not. Of the 196 ever‐subfecund women in our sample, 123 experienced subfecundity while trying to get pregnant; we called these ‘subfecund with intent’. Another 73 women experienced subfecundity while not actively trying to get pregnant; we called these ‘subfecund without intent’. Of the 196 subfecund women, 39% reported having sought treatment. Treatment‐seekers had clearer intentions to get pregnant, were more likely to seek infertility information on their own, and were more likely to self‐define as having fertility problems. Those with more income, more education and lower internal locus of control were more likely to seek medical help. Among the subfecund with intent who pursued medical help, about a fourth had received treatment. The few women who had sought spiritual counselling or non‐conventional help often combined these actions with medical help‐seeking. This study supported the conclusion that common‐sense understandings among subfecund women play an important role in help‐seeking behaviour. From a practical point of view, there is a large unmet need for infertility services and infertility counselling in the United States.  相似文献

Research question: Although the impact of cystic fibrosis on male fertility is well known, very few studies have investigated its effect on female fertility. This study aimed to evaluate the fertility status of women with cystic fibrosis.Design: A questionnaire was sent to 220 women with cystic fibrosis. The questions concerned their desire to become a parent, achievement or not of a pregnancy, the time to become pregnant, the means of achieving pregnancy (spontaneously or with medical assistance) and the outcome of the pregnancy. Ninety-eight patients responded to the questionnaire.Results: Of the 46 women who sought pregnancy, 25 (54%) had at least one live birth without treatment, while 11 (24%) required infertility treatment to obtain a live birth and 10 (22%) had no delivery. The mean time-to-pregnancy was 12 months (1–180). The reasons for preferring not to become pregnant were mainly fear of the interaction between cystic fibrosis and pregnancy and of the transmission of cystic fibrosis to children.Conclusions: Fertility seems to be slightly impaired in women with cystic fibrosis, because 37% of them failed to become pregnant without medical assistance. Because the outcome of pregnancies appears normal, patients should be informed about the possibility of becoming mothers and be made aware of the risk of unwanted pregnancies.  相似文献

OBJECTIVE: To evaluate central nervous system abnormalities in a group of otherwise healthy pregnant women with hyperemesis gravidarum (HG) during the first trimester. STUDY DESIGN: In a case-control study, 17 pregnant women with HG during the first trimester (study group) were compared with 18 pregnant women without nausea and vomiting in pregnancy (NVP). The latter group included women who were planning first-trimester termination of pregnancy for reasons other than health (control group). All the pregnant women enrolled in the study answered a questionnaire and underwent a physical examination, blood tests, urinalysis, EEG, and visual evoked potential (VEP) and brainstem auditory evoked response (BAER) tests. RESULTS: An abnormal EEG was found in 5 of the 17 women in the study group (29.4%), whereas none of the 18 women in the control group had an abnormal EEG (p = 0.013). The VEP and BAER tests were normal among the women in both groups. There were no clinically significant differences between the 2 groups with regard to maternal age, gravidity, parity, weeks of gestational age, blood count, renal function, liver function or electrolytes. Low thyroid stimulating hormone levels were found in 6 of the 17 women in the study group (35.3%) as compared to 1 of the 18 in the control group (5.5%) (p = 0.028). None of the women in either group had hyperthyroidism. HG in previous pregnancies was a significant risk factor for HG in the present pregnancy. CONCLUSION: In pregnant women with HG during the first trimester, the frequency of abnormal EEG findings is significantly higher as compared to that in pregnant women without NVP. However, the mechanism and implications of these findings are yet to be clarified.  相似文献

BACKGROUND AND AIMS: To define the frequency of Sicilian pregnant women taking folic acid during the periconceptional period (three months before and two months after conception) and how many are familiar with the preventive effects of folic acid on NTD. METHODS: 987 pregnant women from eastern Sicily, mainly with low incomes and low levels of education, most with secondary school certificates, underwent biochemical screening for Down's syndrome and NTD in the second trimester of pregnancy. RESULTS: An anencephalous fetus was diagnosed (frequency 0.1%) in a non-risk couple who had not taken folic acid during the periconceptional period: 4.1% (41 cases) of pregnant women reported having taken folic acid before pregnancy and 12.3% (122) during the first two months of pregnancy: five (0.5%) took folic acid during the periconceptional period (three months before conception and two months after). None of the 5 patients with a positive family history of NTD had taken folic acid. In all 122 cases the intake of folic acid supplements during pregnancy started after the positive results of the pregnancy test or echographic evidence of pregnancy, namely between the fifth and eighth week of pregnancy. Only the 5 pregnant women (0.5%) who took folic acid during the periconceptional period were aware of the possibility of preventing NTD through supplements of this vitamin. CONCLUSIONS: Greater efforts must be made to increase periconceptional use of folic acid for the prevention of NTD in pregnant women in Sicily.  相似文献

OBJECTIVES: To determine the recurrence risk of a free trisomy 21 pregnancy. METHODS: Data from the National Down Syndrome Cytogenetic Register (NDSCR), which contains information on nearly all cases of Down syndrome between 1989 and 2001 in England and Wales were used. Among 11 281 women with a Down syndrome pregnancy who had had at least one previous pregnancy there were 95 women who had had a previous Down syndrome pregnancy. RESULTS: Women who have had a previous Down syndrome pregnancy have a constant absolute excess risk above their maternal age-related risk of having a subsequent affected pregnancy. This absolute excess risk is determined by the age at which the affected pregnancy occurred and is higher for younger than for older women. For example, after a Down syndrome pregnancy at age 20, this excess is 0.62% (95% CI: 0.24 to 1.15%) at early second trimester, and, after one at age 40, it is 0.04% (95% CI: 0.01 to 0.07%). CONCLUSION: More precise risk estimates by single year of maternal age for use in genetic counselling are provided, but they need validation from other studies before they are incorporated in the risk estimation routines used in Down syndrome screening programmes.  相似文献

Nausea and vomiting of pregnancy (NVP) affects 80% of pregnancies. Its severe form, hyperemesis gravidarum (HG), results in dehydration, electrolyte imbalance, the need for hospitalisation and can, rarely, be fatal. This was a prospective, open-labelled, controlled, interventional study to evaluate the effectiveness of pre-emptive treatment of NVP symptoms in women who experienced severe NVP or HG in their previous pregnancy. Twenty-five women who reported severe symptoms of NVP with or without HG in their previous pregnancy were recruited and counselled to commence the use of antiemetics as soon as they became aware of the present pregnancy, and no later than the beginning of symptoms. They were followed-up prospectively through the index pregnancy for symptoms of NVP, and were counselled continuously as to how to modify antiemetic doses based on symptoms. A comparison group consisted of randomly selected women also counselled by us for NVP, who had also had severe NVP in the previous pregnancy, but who did not call before a planned pregnancy and thus could not be offered pre-emptive therapy. The recruited women commenced pre-emptive drug therapy for NVP before conception or up to 7 weeks' gestation, before the appearance of NVP symptoms in all cases. In comparison to the previous pregnancy, only eight of these 18 women experienced a HG again in the index pregnancy (P = 0.01). The majority of study the women had an improvement in severity of NVP symptoms compared to the previous pregnancy. In the comparison group (n = 35), symptoms in the index pregnancy remained severe in 28 cases (80%), decreased to moderate in six (16.6%) and decreased to mild in five cases (13.9%). There were five cases of HG in the previous pregnancy and three in the index pregnancy. The pre-emptive group was improved significantly compared to the control group (P = 0.01). Pre-emptive symptom management appears to be effective in preventing severe NVP in general, and HG in particular. Women who have experienced severe NVP in a previous pregnancy may benefit from taking antiemetics before, or immediately at the start of symptoms in a subsequent pregnancy.  相似文献

Pregnancy-related substance use in the United States during 1996-1998   总被引:2,自引:0,他引:2  
OBJECTIVE: To provide a baseline estimate of the national prevalence of pregnancy-related illicit drug use and abstinence rates. METHODS: We analyzed data collected between 1996 and 1998 from the National Household Survey on Drug Abuse, a nationally representative sample survey of 22,303 noninstitutionalized women aged 18-44 years, of whom 1,249 were pregnant. RESULTS: During 1996-1998, 6.4% of nonpregnant women of childbearing age and 2.8% of pregnant women reported that they used illicit drugs. Of the women who used drugs, the relative proportion of women who abstained from illicit drugs after recognition of pregnancy increased from 28% during the first trimester of pregnancy to 93% by the third trimester. However, because of postpregnancy relapse, the net pregnancy-related reduction in illicit drug use at postpartum was only 24%. Marijuana accounted for three-fourths of illicit drug use, and cocaine accounted for one-tenth of illicit drug use. Of those who used illicit drugs, over half of pregnant and two-thirds of nonpregnant women also used cigarettes and alcohol. Among the sociodemographic subgroups, pregnant and nonpregnant women who were young (18-30 years) or unmarried, and pregnant women with less than high school education had the highest rates of illicit drug use. CONCLUSION: The continued burden of illicit drug use during pregnancy calls for policy efforts to enable primary care providers to identify and refer women who use substances to treatment and support services. Prevention of uptake of illicit drug use should be an integral part of public health programs for young women.  相似文献

A pregnant woman with acute hepatitis B virus (HBV) infection had her second pregnancy terminated at 25 weeks' gestation because of fetal ascites and ventriculitis. Meconium peritonitis was also found at autopsy. No HBV DNA but cytomegalovirus (CMV) DNA was detected in the fetal liver and ascitic fluid. Recurrent maternal CMV infection was demonstrated by pre-existing CMV IgG antibodies, high IgG avidity and low IgM levels. After abortion, the patient developed chronic active hepatitis. Nevertheless, having become pregnant again with a new partner, she had an uneventful third pregnancy and gave birth to a healthy boy.  相似文献

OBJECTIVE: To provide national estimates of knowledge about treatments available to reduce mother-to-infant human immunodeficiency virus (HIV) transmission among U.S. women of childbearing age. METHODS: We used data from 55712 women aged 18 to 44 years who responded to questions on antiretroviral treatment in the 2001 Behavioral Risk Factor Surveillance System. We obtained the percentage of women who correctly answered a question on treatment to prevent mother-to-child transmission of HIV and determined factors independently associated with such knowledge using a multiple logistic regression model. RESULTS: Overall, the percentage of women who correctly stated that treatment existed to help prevent mother-to-child transmission of HIV was 58.6% (95% confidence interval 57.9, 59.3). In the multiple logistic regression model that controlled for sociodemographics, having correct knowledge about treatment to prevent mother-to-child HIV transmission was independently associated with being black, younger age (18-34 years), college level education, and having been tested for HIV. Current pregnancy was not an independent predictor of having knowledge about the availability of treatment to prevent mother-to-child transmission. CONCLUSION: Among US women of childbearing age, just over one half had correct knowledge of effective perinatal HIV prevention strategies. Increasing the awareness of these treatments may lead to greater uptake of HIV testing among pregnant women.  相似文献

Nitrofurantoin and congenital abnormalities   总被引:1,自引:0,他引:1  
OBJECTIVE: To study human teratogenic potential of oral nitrofurantoin treatment during pregnancy. MATERIALS and METHODS: Pair analysis of cases with congenital abnormalities and matched population controls in the population-based dataset of the Hungarian Case-Control Surveillance of Congenital Abnormalities, 1980-1996. RESULTS: Of 38,151 pregnant women who had newborn infants without any congenital abnormalities (population control group), 774 (3.4%); of 22,865 case pregnant women who had newborns or fetuses with congenital abnormalities, 1079 (2.8%) and of 812 pregnant women who had newborns or fetuses with Down's syndrome (patient controls), 23 (2.8%) pregnant women were treated with nitrofurantoin. The above differences between population controls and cases may be connected with recall bias, because the case-control pair analysis did not indicate a teratogenic potential of nitrofurantoin use during the second and the third months of gestation, i.e. in the critical period for major congenital abnormalities. CONCLUSION: Treatment with nitrofurantoin during pregnancy does not present detectable teratogenic risk to the fetus.  相似文献

Case

Approximately 3%‐25% of cases of endometrial carcinoma (EC) or atypical endometrial hyperplasia (AH) occur in women aged <40 years and conservative treatment with high‐dose medroxyprogesterone acetate (MPA) is administered to women who wish to preserve their fertility. Here is reported the pregnancy outcomes of patients with EC or AH who received MPA therapy at Tokushima University Hospital, Tokushima, Japan. The frequency of pregnancy and live births among the patients with EC or AH who received conservative treatment, followed by fertility treatment, were analyzed retrospectively.

Outcome

Twelve patients underwent fertility examinations and received fertility treatment immediately after the completion of conservative treatment for EC or AH. One patient had the complication of severe diabetes and total embryo cryopreservation was performed before her diabetes was treated. Among the other 11 patients, 8 (72.7%) became pregnant at least once and 6 (54.5%) experienced at least 1 live birth. Three patients (25.0%) suffered disease recurrence during or after the infertility treatment and all of the recurrences occurred in the EC cohort.

Conclusion

When patients with EC or AH wish to preserve their fertility, it is recommended that prompt and effective fertility treatment, including assisted reproductive technology, should be initiated just after conservative treatment because EC and AH exhibit relatively high recurrence rates among conservatively treated patients.  相似文献

Abstract: Background: Some guidelines encourage mothers to see and hold their babies after stillbirth, which might be traumatizing. The study objective was to investigate the effects of women seeing and holding their stillborn baby on the risk of anxiety and depression in a subsequent pregnancy and in the long term. Methods: Thirty‐seven organizations recruited women who had experienced stillbirth (N = 2,292 of whom 286 reported being pregnant). Anxiety and depressive symptoms were assessed by using the 25‐item Hopkins Symptom Check List. Results: Among nonpregnant women, seeing and holding their stillborn baby were associated with lower anxiety symptoms (OR 0.68, 95% CI 0.49–0.95) and a tendency toward fewer symptoms of depression (OR 0.72, 95% CI 0.51–1.02), compared with pregnant women. Participants who were pregnant also had less depressive symptomatology (OR 0.57, 95% CI 0.43–0.75), but more symptoms of anxiety if they had seen and held their baby (OR 3.79, 95% CI 1.42–10.1). Conclusions: Seeing and holding the baby are associated with fewer anxiety and depressive symptoms among mothers of stillborn babies than not doing so, although this beneficial effect may be temporarily reversed during a subsequent pregnancy.

Women pregnant again after prior perinatal loss fear another loss and thus protect their emotions and avoid prenatal bonding. This phenomenon, emotional cushioning, appears to be a complex self‐protective mechanism and is proposed here as a unique combination of circumstances and responses used by women to cope with the anxiety, uncertainty, and sense of vulnerability experienced in these subsequent pregnancies. Related literature is reviewed to clarify and circumscribe what emotional cushioning is. In this mixed‐methods study, a convenience sample of women pregnant after perinatal loss (N=63) completed the Pregnancy Anxiety Scale during and following pregnancy and responded to questions regarding ‘holding back their emotions’ in pregnancy. The purpose was to describe the range and prevalence of emotional cushioning, to compare pre‐ and post‐natal reports of emotional cushioning, and to examine relationships between emotional cushioning and pregnancy anxiety pre‐ and post‐natally. The majority of women (58.7%) reported some emotional cushioning. Emotional cushioning questions were significantly and positively correlated with pregnancy anxiety. Clinical and research implications are discussed.  相似文献

A national sample of 533 teenage mothers in England and Wales was interviewed in 1979 about their lives, their babies, and their partners. 70 (13%) reported that they had thought about having an abortion. All but 9 of this group talked to someone about this possibility. More than half of these women decided not to pursue, or were deterred from pursuing an abortion after initial discussion with their partner, parents, a doctor, or a friend. 25 women, 5%, of the sample had sought an abortion. Discussion focuses on why none of these women obtained an abortion. At the time they became pregnant, nearly all these women were single. They described their pregnancy as unplanned. They reported that they were initially upset (25%) or had mixed feelings (75%) about the pregnancy. None said that they were pleased about it. 4 of the women interviewed were only 15 or 16 when they became pregnant. 1 women stated that she had no intention of having an abortion and only applied for one to pacify her father who was outraged by her pregnancy. 8 women changed their minds and decided not to pursue the abortion mostly because they decided they wanted to have a baby after all, or for reasons of inertia. The views of their boyfriends prevailed with 2 women. Of the remaining 15 women, 3% of the initial sample, 10 were informed by their doctors that they had come "too late." 6 of these 10 women had visited their doctor before they were 10 weeks pregnant. This may give some cause for concern. 5 women reported that they were refused abortions by their general practitioners or gynecologists without further explanation or on "medical" grounds.  相似文献

The incidence of asymptomatic bacteriuria is reported as 2-14% during pregnancy. Fetal and maternal complications like acute pyelonephritis, hypertension, anemia, preterm labor, low-birth-weight infants and intrauterine growth retardation can be expected. The purpose of this study was to determine the incidence of asymptomatic bacteriuria during pregnancy and its relation to pregnancy complications. The study involved 270 pregnant women up to 32 gestational weeks during a 9-month period. At the initial visit, they were screened with urine culture in order to detect asymptomatic bacteriuria. A control group was formed in a retrospective manner from the first day of the study with 186 pregnant women who delivered in our clinic and who were not screened for asymptomatic bacteriuria. The incidence of asymptomatic bacteriuria was 9.31%. Escherichia coli accounted for 79%, which was the most frequent of the isolates. We observed recurrence and had to apply treatment again to 21.7% of the women. The sensitivity, specificity, positive predictive and negative predictive values of leucocyturia as a screening test for asymptomatic bacteriuria were 91.3%, 83.6%, 45.6% and 98.5%, respectively. We diagnosed preterm labor in six of 23 (26%) with asymptomatic bacteriuria and 16 in 163 (9.3%) women in the urine culture negative group. The ratio acute pyelonephritis in the group which was routinely screened and treated for asymtomatic bacteriuria was 0.5% while the prevalence was 2.1% in the nonscreened group. Considering the relatively high incidence of asymptomatic bacteriuria during pregnancy and the relevant complications, we propose to screen and treat asymptomatic bacteriuria routinely in all pregnant women.  相似文献

ABSTRACT: Background: Actions taken after a stillbirth can affect long‐term psychological morbidity. Our objective was to study how infant bonding and maternal actions after stillbirth are associated with ensuing depressive symptoms. Methods: Using the population‐based Swedish Medical Birth Register, we identified all 380 Swedish‐speaking women who gave birth to singleton stillborn infants in Sweden in 1991. Of these, 314 (83%) completed a postal questionnaire 3 years after the stillbirth. Items included actions taken to bond with the baby and demographics. The association between care‐related factors and later maternal depressive symptoms was quantified using relative risks estimated using multivariable regression. Results: We observed an almost sevenfold increased risk of depressive symptoms for mothers who reported not being with their babies as long as they wished (adjusted risk ratio [RR] 6.9, 95% CI 2.4–19.8). Compared with women who became pregnant again within 6 months, those with no later pregnancy were at higher risk of depressive symptoms (adjusted RR 2.8, 95% CI 0.9–8.4). In addition, compared with women who experienced a stillbirth in their first pregnancy, stillbirth occurring with an infant who was third in the birth order was related to a twofold risk of elevated depressive symptoms (adjusted RR 2.2, 95% CI 0.8–6.4). Furthermore, stillbirth occurring in a fourth or later pregnancy was associated with an almost sevenfold risk of depressive symptomatology (adjusted RR 6.7, 95% CI 2.2–20.5). No evidence of an association was found between other care‐related actions and subsequent maternal depressive symptoms. Conclusions: Our results suggest that a mother being with the stillborn baby for as long as desired and the birth order of the stillbirth may influence her later depressive symptomatology. Compared with mothers who became pregnant again within 6 months, those who did not have a subsequent pregnancy were at higher risk of depressive symptoms at 3 years’ follow‐up.
