Maternal and perinatal complications in pregnant women with urinary tract infection caused by Escherichia coli.

AIM: The incidence of urinary tract infection (UTI) in pregnant women may vary from 5-10% and depends on parity, race, socioeconomic status and anatomical and functional changes in pregnancy. In Mexico, preterm birth accounts for 75% of perinatal deaths and 50% of the neurological sequelae attributable directly to prematurity. The objective of the present study is to describe maternal and perinatal complications in pregnant women with UTI caused by Escherichia coli and to find out the antimicrobial susceptibility pattern. METHODS: A descriptive and longitudinal study of pregnant women admitted to the Women's Hospital in Culiacan, Sinaloa, Mexico, was carried out from January 2013 to December 2014. Patients with E. coli infection were included, and infections caused by other microorganisms were excluded. The sociodemographic variables, causes of hospitalization and the type of maternal and perinatal complications were determined. RESULTS: The causes of admission to the hospital were threatened preterm labor, and fever and threatened abortion. Of 38 patients with threatened preterm labor, 33 went on to delivery, four were preterm births and two were neonatal deaths. E. coli was sensitive to over 90% of piperacillin-tazobactam, amikacin, nitrofurantoin and carbapenems. CONCLUSION: According to this study in a Mexican population, the number one admission diagnosis in women with UTI due to E. coli was threatened preterm labor, and fever and threatened abortion. E. coli was sensitive to more than 90% of piperacillin-tazobactam, amikacin, nitrofurantoin and carbapenems.

Alterted SLIT2/ROBO1 signalling is linked to impaired placentation of missed and threatened miscarriage in early pregnancy.

AIMS: Two-thirds of early pregnancy failures present with reduced trophoblast invasion, and SLIT2/ROBO1 signalling is considered to play an important role in trophoblast function during pregnancy. We investigated SLIT2/ROBO1 signalling associated with missed and threatened miscarriage during early gestation. METHODS AND RESULTS: Human placenta samples were collected from women with missed miscarriage (n = 25), threatened miscarriage (n = 22) and termination of pregnancy controls (n = 32). Corresponding decreases in beta human chorionic gonadotrophin (ß-hCG) levels and shallow trophoblast invasion were observed in patients with missed and threatened miscarriage, immunohistological staining revealed abnormal Slit2 and Robo1, as well as E-cadherin and activating protein-2 alpha (AP-2α) expression in villi and extravillous trophoblasts, and the expression of these proteins were confirmed in villi and decidua of miscarriage material by Western blotting. Using HTR8/SVneo cells, blocking SLIT2/ROBO1 signalling promoted cell migration, proliferation and suppressed differentiation. Moreover, blocking SLIT2/ROBO1 signalling in HTR8/SVneo cells altered trophoblast differentiation-related and angiogenesis-related gene mRNA expression, which also occurred in the tissues of missed and threatened miscarriage. CONCLUSIONS: SLIT2/ROBO1 signalling may regulate trophoblast differentiation and invasion causing restricting ß-hCG production, shallow trophoblast invasion and inhibiting placental angiogenesis in missed and threatened miscarriage during the first trimester.

[Partial molar pregnancy. A case report and literature review]. / Embarazo molar parcial: reporte de un caso y revisión de la bibliografía.

We report the case of a 17 year old patient with partial molar pregnancy and coexistent live fetus of 13 gestational weeks diagnosed by ultrasound, which required the termination of pregnancy for maternal decompensation.

Does the fibrinogen/albumin ratio predict the prognosis of pregnancies with abortus imminens?

OBJECTIVES: To investigate the fibrinogen/albumin ratio (FAR) of pregnant women with abortus imminens (AI) and its prognostic value for predicting spontaneous abortion. METHODS: A total 102 early pregnancies, 52 had been diagnosed with AI and 50 ages and body mass index matched healthy control pregnant women were included in this prospective observational study conducted in the Research and Training Hospital, Balikesir University, Balikesir, Turkey between September 2019 and August 2020. Fibrinogen/albumin values were compared between AI and control group. RESULTS: The rate of spontaneous abortion in AI pregnancies was 26.9% in our study population. Fibrinogen/albumin ratio levels were higher in AI pregnancies than in controls (p=0.0088). The regression analysis have shown that the increased FAR value (odds ratio [OR]: 7.3116 [95% CI: 1.3119 to 40.7507]; p=0.0232) was an independent marker for spontaneous abortion prediction in AI pregnancies. CONCLUSION: Pregnancies with AI have increased levels of FAR compared to healthy pregnancies. Fibrinogen/albumin ratio is an independent marker for predicting spontaneous abortion.

Use of herbal products among 392 Italian pregnant women: focus on pregnancy outcome.

PURPOSE: The present study aimed to explore the use of herbal products among a sample of Italian pregnant women and the possible influence of herbal consumption on pregnancy outcome. METHODS: The study was conducted over a 10-month period (2 days a week, from January to October 2009) at the Maternity wards of Padua and Rovereto Hospital. Data were collected through a face-to-face interview on the basis of a prestructured questionnaire including socio-demographic characteristics of the enrolled subjects, specific questions on herbal use, information about pregnancy and newborn. RESULTS: In total, 392 interviews were considered. One hundred and nine out of 392 women (27.8%) reported to have been taking one or more herbal products during pregnancy, in the 36.7% of cases throughout all pregnancy. The most frequently herbs taken by interviewees were chamomile, licorice, fennel, aloe, valerian, echinacea, almond oil, propolis, and cranberry. Four out of 109 women (3.7%) reported side-effects: constipation after a tisane containing a mix of herbs, rash and itching after local application of aloe or almond oil. The decision to use herbal products was mainly based on personal judgement and on the conviction that these natural substances would be safer than traditional medicines. Users were more often affected by morbidities pregnancy-related and their neonates were more frequently small for their gestational age. An higher incidence of threatening miscarriages and preterm labours was observed among regular users of chamomile and licorice. CONCLUSIONS: This research underlines that the use of herbal products during pregnancy is common among Italian women, not always appropriate and in some cases potentially harmful.

The predictive role of sTWEAK levels in pregnant women with first-trimester vaginal bleeding.

PURPOSE: To investigate the relationships of TNF-related weak inducer of apoptosis (sTWEAK), a cytokine related to the TNF superfamily, its newly described soluble receptor sCD163, and the sTWEAK/sCD163 ratio with perinatal outcomes in women with first-trimester vaginal bleeding. MATERIALS AND METHODS: Seventy (41 threatened abortion and 29 control) gestational-age-matched (6-14 weeks) pregnant women were included in the study. Antenatal complications (gestational diabetes, preeclampsia, intrauterine growth restriction, oligohydramniosis, polyhydramniosis), and perinatal outcomes (delivery mode, birth weight, delivery week) were recorded. Women with vaginal bleeding were divided into subgroups by pregnancy outcome (miscarriage or live birth) and subchorionic hematoma incidence. Statistical analyses were performed using the Student's t test, Mann-Whitney U test, chi-square test, and Pearson's correlation coefficient. p Values <.05 were considered as statistically significant. RESULTS: There were no statistically significant differences in sTWEAK or sCD163 levels, in sTWEAK/sCD163 ratios, or antenatal complications between threatened abortion and control patients. Higher sTWEAK levels were significantly correlated with higher rates of miscarriage in the threatened abortion group (p = .014). sCD163 levels were significantly lower in the subchorionic hematoma subgroup of the threatened abortion group (p = .043). CONCLUSIONS: sTWEAK levels may predict the risk of miscarriage in pregnant women with first-trimester vaginal bleeding.

Vaginal bleeding before 20 weeks gestation due to placental abruption leading to disseminated intravascular coagulation and fetal loss after appearing to satisfy criteria for routine threatened abortion: a case report and brief review of the literature.

We present a case of placental abruption with concomitant disseminated intravascular coagulation in a woman who presented with vaginal bleeding. A 32-year-old pregnant woman at 17 and 4/7 weeks gestation with a 1-month history of intermittent abdominal pain presented to our Emergency Department (ED) with 1 h of vaginal bleeding. Upon initial history, the patient reported that she was diagnosed with "blood behind the placenta" the day before and was discharged on pelvic precautions. An ED ultrasound confirmed the sub-amniotic hematoma with placental hematoma and a viable intrauterine fetus. A low fibrinogen level was suggested for disseminated intravascular coagulation and increasing hemorrhage necessitated dilation and evacuation and multiple units of blood products on an emergent basis. Only a few cases have been described in the literature demonstrating disseminated intravascular coagulation in patients at fewer than 20 weeks gestation with routine ultrasound findings of live intrauterine pregnancy and subchorionic hemorrhage.

von Willebrand disease in pregnancy.

von Willebrand disease is the most prevalent inherited bleeding disorder, affecting up to 1.3% of the population. It is caused by a defect or deficiency of the von Willebrand factor. Women with the condition may not be aware of their condition at the time of childbirth, but they are at high risk of postpartum hemorrhage even days after birth. In this article we briefly review the condition and specific considerations for the antepartum, intrapartum, and postpartum phases. It is important for nurses who care for women during childbirth to have a keen understanding of this condition.

A randomized double-blind controlled trial of the use of dydrogesterone in women with threatened miscarriage in the first trimester: study protocol for a randomized controlled trial.

BACKGROUND: Miscarriage is a common complication of pregnancy occurring in 15-20 % of all clinically recognized pregnancies. Currently, there is still no good scientific evidence to support the routine use of progestogens for the treatment of threatened miscarriage because the existing studies were not large enough to show a significant difference and some of them were not randomized or double-blind. METHODS: This is a double-blind, randomized controlled trial. A total of 400 patients presenting with first-trimester threatened miscarriage will be enrolled. They will be randomized to take dydrogesterone 40 mg per os, followed by 10 mg per os three times a day or placebo until twelve completed weeks of gestation or 1 week after the bleeding has stopped, whichever is longer. The primary outcome is the percentage of miscarriage before 20 weeks of gestation. DISCUSSION: We postulate that the dydrogesterone therapy will significantly reduce the risk of miscarriage in women with threatened miscarriage. TRIAL REGISTRATION: This study is registered at ClinicalTrials.gov, NCT02128685 . Registered on 29 April 2014.

Alpha Lipoic Acid (ALA) effects on subchorionic hematoma: preliminary clinical results.

OBJECTIVE: The clinic use of alpha Lipoic Acid (ALA) is linked to its capability to exert antioxidant effects and, more interestingly, to counteract the pathologic changes of complex networks of cytokines, chemokines and growth factors, restoring their physiological state. The aim of this randomized controlled clinical trial was to test the contribution of oral supplementation of ALA to the standard treatment with Progesterone vaginal suppositories, in healing subchorionic hematomas in patients with threatened miscarriage. Controls were administered only Progesterone suppositories. PATIENTS AND METHODS: Nineteen pregnant women in the first trimester of gestation, with threatened miscarriage and ultrasound evidence of subchorionic hematoma, were included in the trial and randomly divided in two groups: controls, treated with 400 mg Progesterone (200 mg 2 times per day), given by vaginal suppositories, and case study treated with the same Progesterone dosage, plus ALA, given orally at the dose of 600 mg (300 mg 2 times per day, DAV®, Lo.Li. Pharma srl, Italy). Sixteen patients completed the trial. Treatment was performed until complete resolution of the clinical picture. RESULTS: In both groups, the subjects improved significantly but, in general, a better and faster evolution in the major signs of threatened miscarriage was observed in the subjects treated with ALA and Progesterone. In these patients, the speed of resorption of subchorionic hematoma was significantly (p ≤ 0.05) superior compared to controls. The ALA and Progesterone group showed a faster decrease or disappearance of all symptoms than that observed in the control group, however the difference was not significant. CONCLUSIONS: These preliminary results suggest that ALA supplementation significantly contributes to speed up the process of restoration of physiological conditions in threatened miscarriage and ameliorates the medical conditions of both the mothers and the foetus, probably modulating the networks of cytokines, growth factors and other molecules.

Ultrasound signs in threatened abortion and their prognostic significance.

During the first and early second trimesters of pregnancy in 244 consecutive patients with uterine bleeding, ultrasound studies were conducted to determine the cause of bleeding. In 165 of the patients the fetus was alive, and the outcome of pregnancy was successful in 143 (87%) despite the fact that ultrasound scanning revealed a total of 60 abnormalities. In the 22 patients whose pregnancy outcome was unfavorable, the number of abnormalities was significantly higher (P less than .05). The most common ultrasound abnormalities were placenta covering the internal os, fetal growth delay, multiple gestation, and intrauterine hematoma. At ultrasound examination, the presence of one or more abnormalities plus bleeding for three days or more significantly increased the risk to the pregnancy. When the duration of bleeding was less than three days and the ultrasound examination was normal, the risk to the pregnancy was lower (7%) than that of patients who had bled for three days or more and had at least one abnormality on ultrasound examination (24%) (P less than .05).

Office employment, work with video display terminals, and course of pregnancy. Reference mothers' experience from a Finnish case-referent study of birth defects.

In an examination of the possible harmful effects of work in an office environment and the use of a video display terminal (VDT) on the course of pregnancy, the experience of 1,475 reference mothers from a Finnish case-referent study of birth defects was analyzed. The study was based on the national Register of Congenital Malformations, whose data were supplemented with special interviews on mothers' work conditions. The group which worked in an office environment consisted of 239 women, of whom 60 had worked with video display terminals; 805 mothers had not worked in an office. Only mothers who had worked during most of their pregnancy and who had a singleton birth were included; hence 431 women were excluded from the analysis. The information on threatened abortion, length of gestation, birthweight, placental weight, and maternal blood pressure was analyzed. Office work involved no elevated risk of threatened abortion when compared with nonoffice work, and among the VDT users the proportion with symptoms related to an impending early termination of pregnancy was similar to that of other office workers. No unfavorable effects on the length of gestation were observed between the compared groups, and there were no differences in the birthweight of the babies when adjustment was made for gestational age or the other aspects under consideration. Thus the results did not suggest that office employment or work with video display terminals would be harmful for pregnancy.

Physical work load, fetal development and course of pregnancy.

The effects of physical work load during pregnancy were analyzed in connection with a nationwide case-referent study that screened for associations between selected structural malformations and occupational exposures. The strain of the occupational activities of 1475 mothers of malformed infants and an equal number of mothers of noncase babies was assessed from a description of the work tasks by an expert using a standardized method reflecting energy expenditure. The noncase mothers' experience revealed a relation between physical load and growth retardation that has also been suggested by other epidemiologic studies. No relation was found between an increase in mean physical load and the occurrence of threatened abortion; yet work involving much standing had an increased risk. Mothers whose work included occasional high physical loads had more pregnancy-induced hypertension. The data showed unexpected associations between physical load and structural malformations.

Occupational noise exposure and course of pregnancy.

The study examined the possible relation of occupational noise exposure to adverse pregnancy outcomes. The experience of 1,190 reference mothers from a case-referent study based on the Finnish Register of Congenital Malformations was scrutinized. Exposure to noise was blindly assessed from a description of the mother's workday by two industrial hygienists. Women with an estimated level of noise of around 80 dB LAeq(8 h) or higher were considered exposed. Threatened abortion was not associated with noise exposure alone, but, when it was combined with shift work, the adjusted risk was over twofold. The adjusted risk of pregnancy-induced hypertension was twice as high among the mothers exposed to noise in shift work, and the duration of their pregnancy was shorter. The analyses produced indications of a relation between noise and growth retardation which was not connected with shift work. There were significantly ascending trends in the proportions of these outcomes according to increasing exposure intensity.

Velamentous insertion of the umbilical cord and vasa previa.

We report 31 cases with velamentous insertion of the umbilical cord of whom two had coexistent vasa previa. The prevalence of the former was 0.22% and of the latter 0.014%. Perinatal mortality was low, 3.2%, but there was a high rate of complications during pregnancy, such as threatened abortion, antepartum and intrapartum bleeding, premature delivery and fetal distress. Fifteen patients underwent caesarean section. Four of the term infants were small for gestational age. One infant had congenital malformations. The two cases with vasa previa are described in detail. We conclude that velamentous insertion of the umbilical cord should be kept in mind in the differential diagnosis of fetal distress accompanied with antepartum or intrapartum vaginal bleeding.

Pregnancy outcome of patients conceiving within one year after chemotherapy for gestational trophoblastic tumor: a clinical report of 22 cases.

OBJECTIVE: To determine the risk of pregnancy for patients who conceive within one year after successful chemotherapy for gestational trophoblastic tumor (GTT). METHODS: We followed up and analysed retrospectively 22 patients who conceived within one year after receiving chemotherapy for GTT from 1966 through 1996. RESULTS: Of 22 patients, 9 had term delivery, 1 had premature birth, 6 requested induced abortion, and 6 experienced therapeutic abortion because of repeated hydatidiform mole (1 patient), intrauterine death (1), inevitable abortion (1), or threatened abortion (3). The fetal wastage rate was 27.3% (6/22). The incidence of gestational trophoblastic disease (GTD), including hydatidiform mole, was 9.1% (2/22). The incidence of GTT was 4.5%. The average interval between completion of chemotherapy and pregnancy was 9.78 months in the group of term pregnancy and 6.50 months in the group of fetal wastage (P < 0.05). CONCLUSIONS: Patients conceiving within one year after successful chemotherapy for GTT are at higher risk for recurrence of GTD and fetal wastage. Therefore, patients with preserved fertility should practice contraception for at least one year after chemotherapy to get better pregnancy outcome.

[Thrombolytic therapy with rt-PA for thrombosis of tricuspid valve prosthesis during pregnancy]. / Traitement thrombolytique par rt-PA d'une thrombose de prothèse valvulaire tricuspidienne chez une femme enceinte.

The authors report the case of a woman with thrombosis of a tricuspid Saint Jude prosthesis during the fourth month of pregnancy. A first course of thrombolytic therapy with rt-PA reestablished normal prosthetic valve function but was followed by a threatened abortion and severe uterine haemorrhage. An early rethrombosis of the prosthetic valve led to interruption of the pregnancy after failure of a second course of thrombolysis, and to replacement of the tricuspid valve prosthesis. This case illustrates the problems of pregnancy in women with mechanical cardiac prosthetic valves and the difficulties of treatment.

[Repeated cesarean section]. / Il taglio cesareo ripetuto.

Pregnancies after repeated cesarean sections are often considered to carry high maternal and fetal risks. The pregnancy course, intraoperative and postoperative complications and conditions of newborns were compared between 53 patients who had two or more previous cesarean sections and 58 women sectioned for the second time. No statistical difference was found between the two groups except for intraoperative complications.

Pregnancy outcome of threatened abortion with subchorionic hematoma: possible benefit of bed-rest?

BACKGROUND: Bleeding in the first trimester of pregnancy is a common phenomenon, associated with early pregnancy loss. In many instances a subchorionic hematoma is found sonographically. OBJECTIVE: To evaluate the possible benefit of bed-rest in women with threatened abortion and sonographically proven subchorionic hematoma, and to examine the possible relationship of duration of vaginal bleeding, hematoma size, and gestational age at diagnosis to pregnancy outcome. METHODS: The study group consisted of 230 women of 2,556 (9%) referred for ultrasound examination because of vaginal bleeding in the first half of pregnancy, who were found to have a subchorionic hematoma in the presence of a singleton live embryo or fetus. All patients were advised bed-rest at home; 200 adhered to this recommendation for the duration of vaginal bleeding (group 1) and 30 continued their usual lifestyle (group 2). All were followed with repeated sonograms at 7 day intervals until bleeding ceased, the subchorionic hematoma disappeared, or abortion occurred. The groups were compared for size of hematoma, duration of bleeding, and gestational age at diagnosis in relation to pregnancy outcome (spontaneous abortion, term or preterm delivery). RESULTS: The first bleeding episode occurred at 12.6 +/- 3.4 weeks of gestation (range 7-20 weeks) and lasted for 28.8 +/- 19.1 days (range 4-72 days). The women who adhered to bed-rest had fewer spontaneous abortions (9.9% vs. 23.3%, P = 0.006) and a higher rate of term pregnancy (89 vs. 70%, P = 0.004) than those who did not. There was no association between duration of vaginal bleeding, hematoma size, or gestational age at diagnosis of subchorionic hematoma and pregnancy outcome. CONCLUSIONS: Fewer spontaneous abortions and a higher rate of term pregnancy were noted in the bed-rest group. However, the lack of randomization and retrospective design of the outcome data collection preclude a definite conclusion. A large prospective randomized study is required to confirm whether bed-rest has a real therapeutic effect.
