    Profound changes occur in the cervix during pregnancy. In particular, the connective tissue is remodelled. To elucidate the mechanisms behind this process, the metabolism of cervical connective tissue was studied using tissue cultures. Cervical biopsies from non-pregnant and pregnant women were incubated with [35S]sulphate. The proteoglycans of the tissue specimens were purified by ion-exchange and gel chromatography and characterized by SDS/PAGE and by enzymic degradation. In the non-pregnant cervix, the incorporation of [35S]sulphate into the proteoglycans was linear for 48 h. During the first 6 h of incubation the accumulation of chiefly one small labelled proteoglycan (apparent Mr 110,000) substituted with dermatan sulphate was recorded. This is in accordance with the known proteoglycan composition of non-pregnant cervical tissue. In addition, small amounts of two larger radioactive dermatan/chondroitin sulphate proteoglycans (apparent Mr values 220,000 and greater than 500,000) were recorded. After longer periods of incubation the proportion of heparan sulphate proteoglycans increased considerably. The pregnant tissue showed a clearly different composition of labelled proteoglycans. An increased accumulation of the two larger dermatan/chondroitin sulphate proteoglycans was seen in addition to the dominant small dermatan sulphate proteoglycan of the non-pregnant cervix. The rate of accumulation of these two proteoglycans was about 3 times higher in the pregnant tissue, whereas that of the small dermatan sulphate proteoglycan was only increased 2-fold. The fact that the concentration of proteoglycans in the pregnant cervix is approximately one-half of that in the non-pregnant cervix indicates that the turnover of proteoglycans in pregnant cervical tissue is significantly increased. The major effect of this profound change of metabolism was a 50% decrease in proteoglycan content and a 2-fold increased proportion of a dermatan sulphate proteoglycan with an

    The influence of multiple human papillomavirus (HPV) types on detection of concordant incident HPV infections of the cervix or anus following infection at the other anatomic site was examined in a cohort of 897 women. Multiple HPV infections at the anus were not significantly associated with subsequent acquisition of a concordant cervical infection, whereas prior coinfections in the cervix increased risk of a new cervical HPV infection. Incident anal HPV infections following concordant cervical HPV infections increased significantly among women with preexisting cervical or anal coinfections. Potential synergy in acquisition of cervical and anal HPV infections has implications for prophylactic vaccine effectiveness.

    Data about the prevalence of human papillomaviruses (HPV) in African women with normal and abnormal cervical cytology are still scarce. Current HPV vaccines contain HPV types, which mainly represent the HPV epidemiology of industrial countries. As further developments of HPV vaccines are going on, it is necessary to regard regional differences in HPV type prevalence to ensure optimal protection by the vaccine. Vaginal swabs of Ghanaian pregnant women, routinely collected before delivery to rule out bacterial infections causing early onset sepsis, were screened for 12 high-risk (HR), 13 probably/possibly (pHR), and 18 low-risk (LR) HPV types. Most pregnant women come for delivery to the hospital. This was considered as appropriate possibility to have an unselected group of women. HPV DNA were detected in 55/165 women (33.3, 95 % CI 26.3-41.1 %). Thirty-four out of fifty-five (61.8, 95 % CI 47.7-74.3 %) of HPV-positive women were infected with HR and/or pHR HPV types. The five most prevalent HR or pHR HPV types were HPV-52 and HPV-67 (7 women each, 4.2, 95 % CI 1.9-8.9 %), HPV-53 (six women, 3.6, 95 % CI 1.5-8.1 %), HPV-45 (five women, 3.0, 95 % CI 1.1-7.3 %), and HPV-18 (four women, 2.4, 95 % CI 0.8-6.5 %), respectively. HPV-16 was found in two women only (1.2, 95 % CI 0.2-4.8 %). Future HPV vaccine research may devote special interest to HPV-67 and HPV-53 provided further studies confirm their high prevalence in the general population of Sub-Saharan African countries. The true carcinogenic potential of HPV-67, which is a member of species alpha9 including HPV-16, and so far categorized as pHR, should be clarified.

    A sensitive and specific double-antibody enzyme-linked immunoassay, using a synthetic analogue of human relaxin for standard and immunogen, was developed for the measurement of human relaxin (hRLX) in serum and plasma. No cross-reactivity was observed for human insulin, human insulin-like growth factor-I, hGH, human chorionic gonadotropin, hFSH, hLH or human prolactin. The assay was used to monitor RLX concentrations in samples from men, non-pregnant and pregnant women, and in pregnant rhesus monkeys infused with hRLX. RLX was not detected in serum from men nor from non-pregnant women, while a concentration of 600 ng/l was measured in pooled sera from two pregnant women (pregnancies achieved by in-vitro fertilization). Immunoreactive RLX (1.1 micrograms/g) was found in human corpora lutea taken from ectopic pregnancies at 7 weeks. In an experiment with a pregnant rhesus monkey infused with human RLX analogue, less than 1.5% of the maternal concentration was measured in the fetal circulation. Even though preliminary, these data suggest a low level of transfer of human analogue relaxin across the placenta in a rhesus monkey. Further studies of the physiology of RLX in human pregnancy will be facilitated by the availability of this immunoassay.

    AIMS: The purpose of this work– was to study the dynamics of biochemical parameters of human saliva and analyze the features of the chemical composition of the saliva of women with abnormal pregnancy and in periodontitis against pregnancy. MATERIALS AND METHODS: The study included four groups of women: a control group of nonpregnant women of childbearing age (10), pregnant women with physiological pregnancy (24-28 weeks) without any signs of periodontal disease (10), pregnant with a generalized periodontitis I--II degrees in remission (10), women with pathological pregnancy with no signs of periodontal inflammation (10). In each of the groups over two samples of saliva were collected, the first collection of saliva in the morning on an empty stomach. Then mouthwash 0.9% sodium chloride solution was assigned and after 30 minutes the second portion of saliva. By enzyme immunoassay in samples of saliva of control groups of nonpregnant and pregnant women, as well as women with signs of a pathological course of pregnancy, the content of estriol, testosterone, and dehydroepiandrosterone sulfate was determined. STATISTICAL ANALYSIS USED: Statistical data analysis was performed by the standard technique using Student's t-test. RESULTS: The results of biochemical analysis of saliva samples collected before rinsing the mouth with saline in groups of healthy nonpregnant and pregnant women were compared. It was established that during pregnancy the concentration of salivary estriol increases, but in pregnant women with periodontitis, the amount of this hormone in the saliva was significantly reduced. The highest content of testosterone in saliva samples, observed in healthy pregnant women, was significantly higher than nonpregnant women. In pregnant women with periodontitis concentration of testosterone in saliva is reduced, while remaining significantly higher than its level in the saliva of nonpregnant women. The highest concentration of testosterone is observed in the

  4. The regulation of myosin phosphatase in pregnant human myometrium.

    PubMed

    Hudson, Claire A; Bernal, Andrés López

    2012-02-01

    Myometrial smooth muscle contractility is regulated predominantly through the reversible phosphorylation of MYLs (myosin light chains), catalysed by MYLK (MYL kinase) and MYLP (MYL phosphatase) activities. MYLK is activated by Ca2+-calmodulin, and most uterotonic agonists operate through myometrial receptors that increase [Ca2+]i (intracellular Ca2+ concentration). Moreover, there is substantial evidence for Ca2+-independent inhibition of MYLP in smooth muscle, leading to generation of increased MYL phosphorylation and force for a given [Ca2+]i, a phenomenon known as 'Ca2+-sensitization'. ROCK (Rho-associated kinase)-mediated phosphorylation and inhibition of MYLP has been proposed as a mechanism for Ca2+-sensitization in smooth muscle. However, it is unclear to date whether the mechanisms that sensitize the contractile machinery to Ca2+ are important in the myometrium, as they appear to be in vascular and respiratory smooth muscle. In the present paper, we discuss the signalling pathways regulating MYLP activity and the involvement of ROCK in myometrial contractility, and present recent data from our laboratory which support a role for Ca2+-sensitization in human myometrium.

    The consumption of probiotics by pregnant and lactating women may prevent the onset of allergic disorders in their children by increasing the concentrations of immunoactive agents such as cytokines in breast milk. Prebiotics such as fructo-oligosaccharides (FOS) increase the number of beneficial organisms such as bifidobacteria. Thus, prebiotics may have an effect similar to that of probiotics. The objective of the present study was to carry out a comprehensive analysis of mRNA expression in human milk cells to identify changes in the concentrations of cytokines in breast milk after the consumption of FOS (4 g × 2 times/d) by pregnant and lactating women. The microarray analysis of human milk cells demonstrated that the expression levels of five genes in colostrum samples and fourteen genes in 1-month breast milk samples differed more than 3-fold between the FOS and control groups (sucrose group). The mRNA expression level of IL-27, a cytokine associated with immunoregulatory function, was significantly higher in 1-month breast milk samples obtained from the FOS group than in those obtained from the control group. In addition, the protein concentrations of IL-27 in colostrum and 1-month breast milk samples were significantly higher in the FOS group than in the control group. In conclusion, the consumption of FOS by pregnant and lactating women increases the production of IL-27 in breast milk. Future studies will address the association of this phenomenon with the onset of allergic disorders in children.

    The aim of this study was to compare the effect of two known spasmogens, oxytocin and the stable thromboxane receptor mimetic, U46619, on human myometrium treated with the prostaglandin E receptor (EP2) agonist, butaprost (selective for the EP2 receptor). Strips of myometrium from pregnant and non-pregnant donors were set up in a superfusion apparatus. Butaprost was administered as a bolus dose and via infusion. During the infusion of 10(-6) M butaprost, spasmogens were administered as bolus doses. Butaprost caused dose-related inhibition of myometrial activity when administered as a bolus dose (3-100 nmol) and concentration-dependent inhibition during infusion studies (10(-8)-10(-5 )M). Butaprost (10(-6 )M) attenuated the response to U46619 (0.l-10 nmol) in pregnant myometrium, but this difference was not statistically significant. Responses of pregnant myometrium to oxytocin (0.01-0.1 nmol) were significantly attenuated (P<0.05) in the presence of butaprost (10(-6)M). Butaprost physiologically antagonised the oxytocin response, possibly by increasing intracellular cAMP levels. This antagonism was much more marked than that seen with butaprost and U46619. It is unclear why these two types of antagonism differ and this effect is currently being investigated further using other prostanoid and non-prostanoid agents.

    The structural integrity of the cervix in pregnancy is necessary for carrying a pregnancy until term, and the organization of human cervical tissue collagen likely plays an important role in the tissue’s structural function. Collagen fibers in the cervical extracellular matrix exhibit preferential directionality, and this collagen network ultrastructure is hypothesized to reorient and remodel during cervical softening and dilation at time of parturition. Within the cervix, the upper half is substantially loaded during pregnancy and is where the premature funneling starts to happen. To characterize the cervical collagen ultrastructure for the upper half of the human cervix, we imaged whole axial tissue slices from non-pregnant and pregnant women undergoing hysterectomy or cesarean hysterectomy respectively using optical coherence tomography (OCT) and implemented a pixel-wise fiber orientation tracking method to measure the distribution of fiber orientation. The collagen fiber orientation maps show that there are two radial zones and the preferential fiber direction is circumferential in a dominant outer radial zone. The OCT data also reveal that there are two anatomic regions with distinct fiber orientation and dispersion properties. These regions are labeled: Region 1—the posterior and anterior quadrants in the outer radial zone and Region 2—the left and right quadrants in the outer radial zone and all quadrants in the inner radial zone. When comparing samples from nulliparous vs multiparous women, no differences in these fiber properties were noted. Pregnant tissue samples exhibit an overall higher fiber dispersion and more heterogeneous fiber properties within the sample than non-pregnant tissue. Collectively, these OCT data suggest that collagen fiber dispersion and directionality may play a role in cervical remodeling during pregnancy, where distinct remodeling properties exist according to anatomical quadrant.

    OBJECTIVES: to analyze the spatial distribution of reported cases of pregnant women infected by the human immunodeficiency virus and to identify the urban areas with greater social vulnerability to the infection among pregnant women. METHOD: ecological study, developed by means of spatial analysis techniques of area data. Secondary data were used from the Brazilian National Disease Notification System for the city of Recife, Pernambuco. Birth data were obtained from the Brazilian Information System on Live Births and socioeconomic data from the 2010 Demographic Census. RESULTS: the presence of spatial self-correlation was verified. Moran's Index was significant for the distribution. Clusters were identified, considered as high-risk areas, located in grouped neighborhoods, with equally high infection rates among pregnant women. A neighborhood located in the Northwest of the city was distinguished, considered in an epidemiological transition phase. CONCLUSION: precarious living conditions, as evidenced by the indicators illiteracy, absence of prenatal care and poverty, were relevant for the risk of vertical HIV transmission, converging to the grouping of cases among disadvantaged regions.

    Through the theoretical-methodological support of the Liberation Pedagogy, this convergent-care study identified the expectations of pregnant women and their respective partners concerning their participation in humanized birth. Five categories emerged during an educational intervention carried out with groups: choosing the type of delivery; selecting the type of obstetrical care; acknowledging oneself as a critical subject of ones own reality; negotiating with the health team; and acquiring knowledge concerning the delivery process. The study reveals that even though power relations permeate the interactions experienced within healthcare facilities, liberating educational practices can strengthen individuals so they are able to overcome the status quo and transform their obstetrical situation.

    The objectives of this study were to evaluate emtricitabine (FTC) pharmacokinetics in pregnant women and their neonates and to determine the optimal prophylactic dose for neonates after birth to prevent mother-to-child transmission of human immunodeficiency virus (HIV). A total of 38 HIV-infected pregnant women were administered tenofovir disoproxyl fumarate (300 mg)-FTC (200 mg) tablets—two tablets at the initiation of labor and one daily for 7 days postpartum. By pair, 11 maternal, one cord blood, and two neonatal FTC concentrations were measured using a high-performance liquid chromatography-tandem mass spectrometry validated method and analyzed by a population approach. Model and mean estimates (interpatient variability) were a two-compartment model for mothers, with an absorption rate constant of 0.54 h−1 (61%), apparent elimination and intercompartmental clearances of 23.2 (17%) and 6.04 liters·h−1, and apparent central and peripheral volumes of 127 and 237 liters, respectively; an effect compartment linked to maternal circulation for cord blood and a neonatal compartment disconnected, after delivery, with a 10.6-h half-life (30%). After the 400-mg FTC administration, the median population area under the concentration-time curve and the minimal and maximal plasma FTC concentrations in pregnant women were 14.3 mg·liter−1·h and 1.68 and 0.076 mg/liter, respectively. At delivery, median (range) predicted maternal and cord blood FTC concentrations were, respectively, 1.16 (0.14 to 1.99) and 0.72 (0.05 to 1.19) mg·liter−1. We concluded that the 400-mg FTC administration in pregnant women produces higher exposition than does the 200-mg administration in other adults, at steady state. FTC was shown to have good placental transfer (80%). Administering 1 mg FTC/kg as soon as possible after birth or 2 mg/kg 12 h after birth should produce neonatal concentrations comparable to the concentrations observed in adults. PMID:19104016

    The mechanisms governing maintenance of quiescence during pregnancy remain largely unknown. The current study characterizes a stretch-activated, tetraethylammonium-insensitive K(+) current in smooth muscle cells isolated from pregnant human myometrium. This study hypothesizes that these K(+) currents can be attributed to TREK-1 and that upregulation of this channel during pregnancy assists with the maintenance of a negative cell membrane potential, conceivably contributing to uterine quiescence until full term. The results of this study demonstrate that, in pregnant human myometrial cells, outward currents at 80 mV increased from 4.8 ± 1.5 to 19.4 ± 7.5 pA/pF and from 3.0 ± 0.8 to 11.8 ± 2.7 pA/pF with application of arachidonic acid (AA) and NaHCO3, respectively, causing intracellular acidification. Similarly, outward currents were inhibited following application of 10 μM fluphenazine by 51.2 ± 9.8% after activation by AA and by 73.9 ± 4.2% after activation by NaHCO3. In human embryonic kidney (HEK-293) cells stably expressing TREK-1, outward currents at 80 mV increased from 91.0 ± 23.8 to 247.5 ± 73.3 pA/pF and from 34.8 ± 8.9 to 218.6 ± 45.0 pA/pF with application of AA and NaHCO3, respectively. Correspondingly, outward currents were inhibited 89.5 ± 2.3% by 10 μM fluphenazine following activation by AA and by 91.6 ± 3.4% following activation by NaHCO3. Moreover, currents in human myometrial cells were activated by stretch and were reduced by transfection with small interfering RNA or extracellular acidification. Understanding gestational regulation of expression and gating of TREK-1 channels could be important in determining appropriate maintenance of uterine quiescence during pregnancy.

    The incidence of infection with the human immunodeficiency virus (HIV) is increasing among women of childbearing age. Women now account for 18% of the total number of cases of the acquired immunodeficiency syndrome (AIDS), compared with 9% a decade ago. The medical care of pregnant HIV-infected women must take into account the high prevalence of substance abuse, preceded and often accompanied by significant levels of physical, emotional, and sexual trauma, and the concomitant stigmatization of these women in their families and communities. Pregnancy is often a time when women are motivated to make major positive behavioral and life-style changes. To do this, they need ongoing, multidisciplinary counseling and support, with recognition that progress may be intermittent and slow. The Special Prenatal Care Program at Bellevue Hospital is described to show the level of resource commitment that is needed as well as the nearly universal acceptance of voluntary HIV counseling and testing in these conditions. Trends in permanency planning for the children of HIV-infected women are described. Future research needs are outlined, including female-specific drug treatment and more effective contraceptive technology for both men and women.

    The appearance of gap junctions (GJs) between myometrial smooth muscle cells is one of the major events associated with the onset of labor. We have employed dye-coupling and electrical-current injection techniques to study the mechanisms by which steroid hormones regulate GJs in term pregnant myometrium of women before labor. Progesterone (P4) did not alter the input resistance (Ro) of the tissues when added to Tyrode's solution, which was used as control treatment. Octanol, the putative gap junctional uncoupling agent, increased the Ro of the cells compared to the control and P4-treated groups. The membrane potential (Em) did not differ between these groups. However, when P4 was applied after the tissue was perfused with estradiol (E2), the results changed dramatically: the Em hyperpolarized, and the Ro increased. Octanol increased the Ro in E2-treated tissues, but did not affect the Em. Consecutive application of E2, octanol, E2, and P4 resulted in rapid changes in the Ro of the cells. Dye-coupling was mostly detected between cells from controls and E2-treated tissues. These results indicate that P4 exerts its effects in the presence of E2 and that P4 has rapid effects on the intercellular communication between human myometrial cells.

    After the 2010 Haiti earthquake, Zanmi Lasante, a local health care organization, implemented a collaborative stepped-care model to address depression in community and primary care settings in rural Haiti. Specialized community health workers, the ajans santé, collaborate with local psychologists and primary care doctors to offer home-based evaluation, support, and follow-up. The services include brief interpersonal psychotherapy (IPT) and/or medication to persons who met locally defined criteria for depression. A cross-national (Haiti-United States) expert mental health team has been overseeing the program. The present IPT supervision case of a severely depressed, physically abused, and pregnant young woman illustrates the U.S.-based supervisor's internal struggle to reconcile awareness of and respect for local norms while maintaining a human rights-based framework. It also highlights the critical role of community health workers in addressing the mental health treatment gap in regions plagued by extreme poverty and adversity.

    Two experimental mouse models were tested for their suitability in measuring virulence of two human and two bovine isolates (types Ia and III) of group B streptococci. In the first model, the kinetics of the number of bacteria in the spleen, liver, and placenta of mice inoculated intravenously on day 16 of pregnancy were monitored for 48 h after infection. In the second model, lethality and abortion were recorded for mice inoculated on day 13 of pregnancy. Levels of colonization in spleens or livers and lethality were significantly greater (P less than 0.001) for human isolates than for bovine isolates. In contrast, no statistically significant differences in the ability to colonize placentas and to induce abortions were noted between human and bovine isolates. The results showed that pregnant mice were more sensitive than nonpregnant mice to a challenge with group B streptococci. The results also suggest that placental colonization and abortion could be a suitable mouse model in evaluating the virulence of human and bovine isolates of group B streptococci. PMID:3880731

    Prematurity is the most important complication contributing to neonatal morbidity and mortality. It is the untimely activation of the terminal events of human parturition that lead to preterm birth, with inflammation playing a driving role in initiating uterine contractions. The purpose of this study was to investigate the role of Forkhead box O1 (FOXO1), a pro-inflammatory modulator, during human parturition. FOXO1 mRNA expression was quantified using qRT-PCR, and protein expression using Western blotting in myometrial biopsies from pregnant non-labouring and labouring women at term. In addition, the effect of FOXO1 knockdown in human myometrial cells on IL-β-stimulated expression of pro-inflammatory mediators was investigated. Levels of FOXO1, at both the gene and protein levels, were higher in myometrium obtained from women in labour compared with samples taken from non-labouring women. FOXO1 deletion in myometrial cells attenuated the capacity of IL-1β to induce inflammatory gene expression. Specifically, FOXO1 knockdown significantly decreased IL-1β-induced IL-6 and IL-8 expression; production and COX-2 expression and subsequent prostaglandin (PGE2 and PGF2α) release; and MMP-9 mRNA expression and activity. In summary, this study demonstrates for the first time the potential role of FOXO1 inflammatory events of both physiological and pathological labour in human myometrium, and may provide a therapeutic target in the management of preterm labour.

    Prostaglandins (PG) E2, PGF2alpha and thromboxane (TX) mediate uterine contractility by targeting prostonoid EP, FP and TP receptors respectively. The aim of this study was to elucidate the function of these receptors in isolated human myometrium taken at term gestation prior to and following labour onset. Lower segment myometrial strips were immersed in organ baths in oxygenated Krebs' solution at 37 degrees C and connected to isometric force transducers. After equilibration, spontaneous activity and concentration responses to PGE2, PGF2alpha and U46619 (a stable TX mimetic) were measured as area under the curve and expressed as a percentage of the final contraction induced by hypotonic shock. Results were expressed as arithmetic means+/-s.e.m. and analysed using two-way ANOVA with Bonferroni's post hoc test. Myometrium excised at late gestation displayed the greatest spontaneous activity compared with the tissues taken during labour (P<0.001). Excitation evoked by PGF2alpha (P<0.01) and PGE2 at 10(-5) mol/l were attenuated after labour onset. U46619 consistently stimulated concentration-dependent contractions (P<0.001) and selective antagonists confirmed TP-mediated effects. The maintained responses to TX indicate crucial roles for TP receptors in the muscular tonus of the parturient uterus. This receptor and its secondary messenger system represent effective myometrial targets for tocolytic agents in both pregnancy and labour-associated disorders.

  18. Endocrine-Immune Interactions in Pregnant Non-Human Primates With Intrauterine Infection

    Preterm birth remains the most common cause of perinatal mortality. Although the causes of preterm labor are multifactorial and vary according to gestational age, preterm labor and term labor share common cellular and molecular mechanisms, including stimulation of the fetal hypothalamic-pituitary-adrenal (HPA) axis and endocrine/immune system interactions. We have developed a non-human primate experimental model for intrauterine infection and preterm labor using chronically instrumented rhesus monkeys (Macaca mulatta) with timed gestations. We have documented the temporal and quantitative relationships among intrauterine infection, the synthesis and release of proinflammatory cytokines, prostaglandins, and fetal-placental steroid biosynthesis in this model. Infection-induced preterm parturition is characterized by significant elevations in amniotic fluid proinflammatory cytokines and by increases in fetal adrenal steroid biosynthesis, but not by corresponding increases in placental estrogen biosynthesis characteristic of spontaneous parturition. This suggests that activation of the fetal HPA axis by the stress of infection is accompanied by placental dysfunction and also that infection-induced preterm parturition is not dependent upon the increased estrogen biosynthesis observed in spontaneous parturition. These different endocrine and immune responses have important diagnostic and therapeutic implications in the management of preterm labor. PMID:18476167

    Human parechovirus type 3 (HPeV3) can cause serious conditions, such as sepsis and encephalitis, in neonates, but available data are lacking in adults. Here, we report a case of pregnancy with HPeV3 infection. A 28-year-old woman at 36 weeks' gestation was admitted because of myalgia and muscle weakness. The grip strength was 6.0kg on her right hand, and 2.5kg on her left hand. The symptoms, probably due not to myositis but to fasciitis, gradually improved with conservative treatment, but labor pains with genital bleeding unexpectedly developed three days after admission. Obstetric consultation was obtained and cesarean section was performed with no complication. A real-time polymerase chain reaction assay for the detection of viral genomic ribonucleic acid against HPeV showed positive results in pharyngeal swabs, feces, and blood, and negative results in the placenta, umbilical cord, umbilical cord blood, amniotic fluid, and breast milk. The HPeV3 was genotyped by sequencing of the VP1 region. She had recovered fully and was discharged with her infant in a stable condition.

    We measured serum dBPA in non-pregnant and pregnant female rhesus monkeys, fetuses and amniotic fluid. dBPA was administered by a daily oral bolus or sc implantation of Silastic capsules; both resulted in daily average serum unconjugated dBPA concentrations of <1ng/ml. We observed lower serum concentrations of unconjugated dBPA in pregnant females relative to pre-pregnancy values, and generally lower concentrations in fetal serum than in maternal serum. Differences in pharmacokinetics of dBPA were evident between pre-pregnancy, early and late pregnancy, likely reflecting changes in maternal, fetal and placental physiology. The serum ratio of conjugated to unconjugated dBPA after continuous sc release of dBPA was similar to values reported in human biomonitoring studies and markedly lower than with oral administration, suggesting oral bolus exposure is not an appropriate human exposure model. We report elsewhere that there were numerous adverse effects on fetuses exposed to very low serum dBPA in these studies.

    Background Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) are the two most important agents of infectious diseases. Both HBV and HIV share common modes of transmission and have serious effects on both pregnant women and infants. In Bahir Dar city administration, there is a scarcity of information on sero-prevalence of HIV and HBV infection among pregnant women. The main objective of this study was to assess sero-prevalence and risk factors of HIV and HBV infection among pregnant women attending antenatal care in Bahir Dar city, Northwest Ethiopia. Methods A cross-sectional study was conducted from March 2013 to April 2013. Socio-demographic and explanatory variables were collected using a structured questionnaire by face to face interview. Hepatitis B surface antigen (HBsAg) was detected using an enzyme linked immunosorbent assay (ELISA). HIV infection was also detected using the national HIV test algorithms. The results were analyzed with descriptive statistics and binary logistic regression. The odds ratio and 95% Confidence intervals were calculated. Results A total of 318 pregnant women with the mean age of 25.72 (SD. ±5.14) years old were enrolled. Overall, 21/318 (6.6%) and 12 /318 (3.8%) of the pregnant women were positive for HIV and HBsAg, respectively. Of these, HIV/HBV co-infection rate was 4 (19.0%). Previous history of blood transfusion (AOR = 3.7, 95% CI, 9.02-14.84), body tattooing (AOR = 5.7, 95% CI, 1.24-26.50), history of surgery (AOR = 11.1, 95% CI, 2.64-46.88) and unsafe injection (AOR = 5.6, 95% CI, 1.44-22.19) were significantly associated with HBV infection. Previous history of piercing with sharp materials (AOR = 3.0, 95% CI 1.17-7.80) and history of abortion (AOR = 6.6, 95% CI 2.50-17.71) were also statistically significant for HIV infection. Conclusions This study indicates that HIV and HBV infections are important public health issues in our region that need to be addressed. All pregnant women need

    Pre-eclampsia, the development of hypertension and proteinuria or end-organ damage during pregnancy, is a leading cause of both maternal and fetal morbidity and mortality, and there are no effective clinical treatments for pre-eclampsia aside from delivery. The development of pre-eclampsia is characterized by maladaptation of the maternal immune system, excessive inflammation and endothelial dysfunction. We have reported that detection of extracellular RNA by the Toll-like receptors (TLRs) 3 and 7 is a key initiating signal that contributes to the development of pre-eclampsia. PLacental eXpanded (PLX-PAD) cells are human placenta-derived, mesenchymal-like, adherent stromal cells that have anti-inflammatory, proangiogenic, cytoprotective and regenerative properties, secondary to paracrine secretion of various molecules in response to environmental stimulation. We hypothesized that PLX-PAD cells would reduce the associated inflammation and tissue damage and lower blood pressure in mice with pre-eclampsia induced by TLR3 or TLR7 activation. Injection of PLX-PAD cells on gestational day 14 significantly decreased systolic blood pressure by day 17 in TLR3-induced and TLR7-induced hypertensive mice (TLR3 144-111 mmHg; TLR7 145-106 mmHg; both P<0.05), and also normalized their elevated urinary protein:creatinine ratios (TLR3 5.68-3.72; TLR7 5.57-3.84; both P<0.05). On gestational day 17, aortic endothelium-dependent relaxation responses improved significantly in TLR3-induced and TLR7-induced hypertensive mice that received PLX-PAD cells on gestational day 14 (TLR3 35-65%; TLR7 37-63%; both P<0.05). In addition, markers of systemic inflammation and placental injury, increased markedly in both groups of TLR-induced hypertensive mice, were reduced by PLX-PAD cells. Importantly, PLX-PAD cell therapy had no effects on these measures in pregnant control mice or on the fetuses. These data demonstrate that PLX-PAD cell therapy can safely reverse pre-eclampsia-like features during

    Since the introduction of drugs to prevent vertical transmission of HIV, the purpose of and approach to HIV testing of pregnant women has increasingly become an area of major controversy. In recent years, many strategies to increase the uptake of HIV testing have focused on offering HIV tests to women in pregnancy-related services. New global guidance issued by the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) specifically notes these services as an entry point for provider-initiated HIV testing and counseling (PITC). The guidance constitutes a useful first step towards a framework within which PITC sensitive to health, human rights and ethical concerns can be provided to pregnant women in health facilities. However, a number of issues will require further attention as implementation moves forward. It is incumbent on all those involved in the scale up of PITC to ensure that it promotes long-term connection with relevant health services and does not result simply in increased testing with no concrete benefits being accrued by the women being tested. Within health services, this will require significant attention to informed consent, pre- and post-test counseling, patient confidentiality, referrals and access to appropriate services, as well as reduction of stigma and discrimination. Beyond health services, efforts will be needed to address larger societal, legal, policy and contextual issues. The health and human rights of pregnant women must be a primary consideration in how HIV testing is implemented; they can benefit greatly from PITC but only if it is carried out appropriately.

  4. HIV testing among pregnant women living with HIV in India: are private healthcare providers routinely violating women’s human rights?

    PubMed Central

    2014-01-01

    Background In India, approximately 49,000 women living with HIV become pregnant and deliver each year. While the government of India has made progress increasing the availability of prevention of mother-to-child transmission of HIV (PMTCT) services, only about one quarter of pregnant women received an HIV test in 2010, and about one-in-five that were found positive for HIV received interventions to prevent vertical transmission of HIV. Methods Between February 2012 to March 2013, 14 HIV-positive women who had recently delivered a baby were recruited from HIV positive women support groups, Government of India Integrated Counseling and Testing Centers, and nongovernmental organizations in Mysore and Pune, India. In-depth interviews were conducted to examine their general experiences with antenatal healthcare; specific experiences around HIV counseling and testing; and perceptions about their care and follow-up treatment. Data were analyzed thematically using the human rights framework for HIV testing adopted by the United Nations and India’s National AIDS Control Organization. Results While all of the HIV-positive women in the study received HIV and PMTCT services at a government hospital or antiretroviral therapy center, almost all reported attending a private clinic or hospital at some point in their pregnancy. According to the participants, HIV testing often occurred without consent; there was little privacy; breaches of confidentiality were commonplace; and denial of medical treatment occurred routinely. Among women living with HIV in this study, violations of their human rights occurred more commonly in private rather than public healthcare settings. Conclusions There is an urgent need for capacity building among private healthcare providers to improve standards of practice with regard to informed consent process, HIV testing, patient confidentiality, treatment, and referral of pregnant women living with HIV.

    Background Herpes simplex virus 1 (HSV-1) is normally associated with orofacial (orolabial) infections and encephalitis, whereas HSV-2 usually causes genital infections and can be transmitted from infected mothers to neonates. The evidence suggesting that HSV is facilitating the spread of the global human immunodeficiency virus (HIV) epidemic and the risk posed by these synergies to neonates in developing countries informed this study. Objectives To determine the seroprevalence and co-infection of HIV and HSV, as well as their associated risk factors, in Lokoja, Nigeria. Methods This was a hospital-based cross-sectional, prospective study, which was carried out among pregnant women attending the antenatal clinic at the federal medical centre in Lokoja, Nigeria. sociodemographic characteristics and HIV-HSV status were determined by the use of a structured questionnaire and immunoassay kits, respectively. All data were analyzed using Stata statistical software (version 12), and the level of significance was determined to be P < 0.05 using the chi-square test. Results Of the 250 pregnant women screened for HIV and HSV, 154 (61.6%) were in the 2nd trimester of gestation, and all of the co-infected respondents were in their 2nd trimester. Only six (2.4%) of the respondents tested positive for HIV, with all six (100%) showing positivity for HSV so the co-infection rate was six (2.4%). Co-infection was found to occur between the ages of 15 and 35 years, while higher age groups did not show any co-infection. Parity, level of education, and history of painful genital ulcers had no significant association with co-infection. Conclusions Advocacy and publicity to raise awareness of the potential public health impact of HSV and HIV co-infection in Nigeria, where anti-HSV testing is not generally performed in all populations, is therefore recommended.

    This study investigated the rate of human papillomavirus (HPV) persistence, associated risk factors, and predictors of cytological alteration outcomes in a cohort of human immunodeficiency virus-infected pregnant women over an 18-month period. HPV was typed through L1 gene sequencing in cervical smears collected during gestation and at 12 months after delivery. Outcomes were defined as nonpersistence (clearance of the HPV in the 2nd sample), re-infection (detection of different types of HPV in the 2 samples), and type-specific HPV persistence (the same HPV type found in both samples). An unfavourable cytological outcome was considered when the second exam showed progression to squamous intraepithelial lesion or high squamous intraepithelial lesion. Ninety patients were studied. HPV DNA persistence occurred in 50% of the cases composed of type-specific persistence (30%) or re-infection (20%). A low CD4+T-cell count at entry was a risk factor for type-specific, re-infection, or HPV DNA persistence. The odds ratio (OR) was almost three times higher in the type-specific group when compared with the re-infection group (OR = 2.8; 95% confidence interval: 0.43-22.79). Our findings show that bonafide (type-specific) HPV persistence is a stronger predictor for the development of cytological abnormalities, highlighting the need for HPV typing as opposed to HPV DNA testing in the clinical setting.

    Uterine contractions are tightly regulated by the electrical activity of myometrial smooth muscle cells (MSMCs). These cells require a depolarizing current to initiate Ca2+ influx and induce contraction. Cationic leak channels, which permit a steady flow of cations into a cell, are known to cause membrane depolarization in many tissue types. Previously, a Gd3+-sensitive, Na+-dependent leak current was identified in the rat myometrium, but the presence of such a current in human MSMCs and the specific ion channel conducting this current was unknown. Here, we report the presence of a Na+-dependent leak current in human myometrium and demonstrate that the Na+-leak channel, NALCN, contributes to this current. We performed whole-cell voltage-clamp on fresh and cultured MSMCs from uterine biopsies of term, non-laboring women and isolated the leak currents by using Ca2+ and K+ channel blockers in the bath solution. Ohmic leak currents were identified in freshly isolated and cultured MSMCs with normalized conductances of 14.6 pS/pF and 10.0 pS/pF, respectively. The myometrial leak current was significantly reduced (P < 0.01) by treating cells with 10 μM Gd3+ or by superfusing the cells with a Na+-free extracellular solution. Reverse transcriptase PCR and immunoblot analysis of uterine biopsies from term, non-laboring women revealed NALCN messenger RNA and protein expression in the myometrium. Notably, ∼90% knockdown of NALCN protein expression with lentivirus-delivered shRNA reduced the Gd3+-sensitive leak current density by 42% (P < 0.05). Our results reveal that NALCN, in part, generates the leak current in MSMCs and provide the basis for future research assessing NALCN as a potential molecular target for modulating uterine excitability.

    Background. It is widely assumed that the uterine cavity in non-pregnant women is physiologically sterile, also as a premise to the long-held view that human infants develop in a sterile uterine environment, though likely reflecting under-appraisal of the extent of the human bacterial metacommunity. In an exploratory study, we aimed to investigate the putative presence of a uterine microbiome in a selected series of non-pregnant women through deep sequencing of the V1-2 hypervariable region of the 16S ribosomal RNA (rRNA) gene. Methods. Nineteen women with various reproductive conditions, including subfertility, scheduled for hysteroscopy and not showing uterine anomalies were recruited. Subjects were highly diverse with regard to demographic and medical history and included nulliparous and parous women. Endometrial tissue and mucus harvesting was performed by use of a transcervical device designed to obtain endometrial biopsy, while avoiding cervicovaginal contamination. Bacteria were targeted by use of a barcoded Illumina MiSeq paired-end sequencing method targeting the 16S rRNA gene V1-2 region, yielding an average of 41,194 reads per sample after quality filtering. Taxonomic annotation was pursued by comparison with sequences available through the Ribosomal Database Project and the NCBI database. Results. Out of 183 unique 16S rRNA gene amplicon sequences, 15 phylotypes were present in all samples. In some 90% of the women included, community architecture was fairly similar inasmuch B. xylanisolvens, B. thetaiotaomicron, B. fragilis and an undetermined Pelomonas taxon constituted over one third of the endometrial bacterial community. On the singular phylotype level, six women showed predominance of L. crispatus or L. iners in the presence of the Bacteroides core. Two endometrial communities were highly dissimilar, largely lacking the Bacteroides core, one dominated by L. crispatus and another consisting of a highly diverse community, including Prevotella spp

    Teenagers who are pregnant face many difficult issues, and counseling by physicians can be an important source of help. We suggest guidelines for this counseling, beginning with a review of the scope and consequences of adolescent pregnancy. Communication strategies should be aimed at building rapport with techniques such as maintaining confidentiality, avoiding judgmental stances, and gearing communication to cognitive maturity. Techniques for exploring family relationships are useful because these relationships are key influences on subsequent decisions and behaviors. We discuss topics related to abortion and childbearing, such as safety, facilitation of balanced decision making, the use of prenatal care, and the formulation of long-term plans. Physicians who can effectively discuss these topics can help pregnant teenagers make informed decisions and improve their prospects for the future.

  14. Vaccinations for pregnant women.

    In the United States, eradication and reduction of vaccine-preventable diseases through immunization has directly increased life expectancy by reducing mortality. Although immunization is a public priority, vaccine coverage among adult Americans is inadequate. The Institute of Medicine, the Community Preventive Services Task Force, and other public health entities have called for the development of innovative programs to incorporate adult vaccination into routine clinical practice. Obstetrician-gynecologists are well suited to serve as vaccinators of women in general and more specifically pregnant women. Pregnant women are at risk for vaccine-preventable disease-related morbidity and mortality and adverse pregnancy outcomes, including congenital anomalies, spontaneous abortion, preterm birth, and low birth weight. In addition to providing direct maternal benefit, vaccination during pregnancy likely provides direct fetal and neonatal benefit through passive immunity (transplacental transfer of maternal vaccine-induced antibodies). This article reviews: 1) types of vaccines; 2) vaccines specifically recommended during pregnancy and postpartum; 3) vaccines recommended during pregnancy and postpartum based on risk factors and special circumstances; 4) vaccines currently under research and development for licensure for maternal-fetal immunization; and 5) barriers to maternal immunization and available patient and health care provider resources.

    Sedentary behavior has been associated with adverse health outcomes among pregnant women; however, few studies have characterized sedentary behavior patterns in this population. We described patterns of accelerometer-determined indicators of sedentary behavior among a national sample of US pregnant (n = 234) women and non-pregnant (n = 1146) women participating in the NHANES 2003-06 cycles. We included women with ≥ 4 days of accelerometer wear of ≥ 10 h/day. A count threshold of < 100 cpm was used to describe sedentary behavior as: 1) total accumulated sedentary time by bout length categories; 2) accumulated sedentary time within discrete bout length categories; 3) mean, median, and usual bout length; and 4) and bout frequency. Both non-pregnant and pregnant women spent up to 60% of their accelerometer wear time in sedentary behavior depending on the minimum bout threshold applied. Sedentary time was higher among pregnant women compared to non-pregnant women when lower bout thresholds (i.e. 10 min or less) were applied. The majority of total sedentary time was accumulated in bouts lasting < 10 min. The women averaged less than two prolonged sedentary bouts (i.e., ≥ 30 min) per day, which accounted for nearly 20% of total accumulated sedentary time. When applying a minimum threshold of at least 15 min, sedentary time increased across pregnancy trimesters, while sedentary time was similar across trimesters when using lower thresholds. These findings provide the first characterization of accelerometer-determined indicators of sedentary behavior in pregnant women. The minimum bout threshold applied influenced estimates of sedentary time and patterns sedentary time accumulation across pregnancy trimesters.

    Aim. The aim of this study was to evaluate the efficacy of lymph drainage to reduce edema of pregnant women. Method. Pregnant women (30 limbs) from the Obstetrics Outpatient Clinic of the Medical School of Santa Casa in São Paulo in the period December 2009 to May 2010 were enrolled in this quantitative, prospective study. The patients, in the 5th to 8th months of gestation, were submitted to one hour of manual lymph drainage of the legs. The volume of the legs was measured by water displacement volumetry before and after one hour of drainage using the Godoy & Godoy manual lymph drainage technique. The paired t-test was used for statistical analysis with an alpha error of 5% being considered significant. Results. Manual lymph drainage significantly reduced swelling of the legs of pregnant women during the day (P = 0.04). Conclusion. Manual lymph drainage helps to reduce limb size during the day of pregnant women.

  2. Antithrombotic therapy for pregnant women.

    Coagulability increases during pregnancy, and thromboembolism can easily occur. Venous thromboembolism is a cause of death in pregnant women, but arterial thrombosis such as ischemic stroke in pregnancy is also not uncommon. In pharmacotherapy for thromboembolism in pregnant women, fetal toxicity and teratogenicity must be carefully considered. As anticoagulants in pregnant women, unfractionated heparin and low-molecular-weight heparin are recommended, but warfarin is not recommended since it has a low molecular weight and crosses the placenta. Various types of new oral anticoagulant drugs have been available in Japan since 2011. However, the Japanese package inserts for these anticoagulants advise quite cautious administration in pregnant women. The guidelines on pregnant women include less information about antiplatelet drugs than anticoagulant drugs. Aspirin may cause teratogenicity and fetal toxicity, and perinatal mortality is increased. However, when low doses of aspirin are administered as antiplatelet therapy, the US Food and Drug Administration has assigned pregnancy category C, and treatment is relatively safe. Neurosurgeons and neurologists commonly encounter pregnant women with thromboembolism, such as ischemic stroke. Up-to-date information and correct selection of drugs are necessary in consultation with specialists in perinatal care.

    The binding of prostaglandins E1 and F2 alpha has been studied in the human myometrium and cervix during the menstrual cycle and in the myometrium of pregnant patients at term before and during labor. Tritium-labeled prostaglandin E1 and F2 alpha binding was saturable and reversible. Scatchard analysis of tritium-labeled prostaglandin E1 binding was linear, which suggests a single class of high-affinity binding sites with an estimated apparent equilibrium dissociation constant of 2.5 to 5.4 nmol/L and inhibitor affinities of 0.9, 273, 273, and 217 nmol/L for prostaglandins E2, A1, B1, and F2 alpha, respectively. Scatchard analysis of tritium-labeled prostaglandin F2 alpha, binding was also linear, but the affinity of these binding sites was much lower, with an average dissociation constant of 50 nmol/L and inhibitor affinities of 1.6, 2.2, and 11.2 nmol/L for prostaglandins E1, E2, and A1, respectively. In nonpregnant patients, the concentrations and affinities of tritium-labeled prostaglandin E1 binding sites were similar in the myometrium during the proliferative and secretory phases of the menstrual cycle, but the concentration of these sites was much lower in the cervix. The concentration of the tritium-labeled prostaglandin E1 binding sites was significantly lower in the myometrium of pregnant patients at term than in the myometrium of nonpregnant patients. The concentrations and affinities of tritium-labeled prostaglandin E1 binding sites were not significantly different in the upper and lower myometrium of pregnant patients at term or in the myometrium of such patients before and during labor. The concentrations of the tritium-labeled prostaglandin F2 alpha binding sites during the menstrual cycle and in pregnancy at term were similar to those of tritium-labeled prostaglandin E1 binding sites.

    The aglycone forms of three steroidal glycoalkaloids-solanidine (derived by hydrolytic removal of the carbohydrate side chain from the potato glycoalkaloids alpha-chaconine and alpha-solanine), solasodine (derived from solasonine in eggplants) and tomatidine (derived from alpha-tomatine in tomatoes)-were evaluated for their effects on liver weight increase (hepatomegaly) in non-pregnant and pregnant mice and on fecundity in pregnant mice fed for 14 days on a diet containing 2.4 mmol/kg of aglycone. In non-pregnant mice, observed ratios of % liver weights to body weights (%LW/BWs) were significantly greater than those of the control values as follows (all values in % vs matched controls+/-S.D.): solanidine, 25.5+/-13.2; solasodine 16.8+/-12.0; and tomatidine, 6.0+/-7.1. The corresponding increases in pregnant mice were: solanidine, 5.3+/-10.7; solasodine, 33.1+/-15.1; tomatidine, 8.4+/-9.1. For pregnant mice (a) body weight gains were less with the algycones than with controls: solanidine, -36.1+/-14.5; solasodine, -17.9+/-14.3; tomatidine, -11.9+/-18.1; (b) litter weights were less than controls: solanidine, -27.0+/-17.1; solasodine, -15.5+/-16.8; tomatidine, no difference; (c) the %LTW/BW ratio was less than that of the controls and was significant only for solasodine, -8.7+/-13.7; and (d) the average weight of the fetuses was less than the controls: solanidine, -11.2+/-15.2; solasodine, -11.4+/-9.4; tomatidine, no difference. Abortion of fetuses occurred in five of 24 pregnant mice on the solanidine and none on the other diets. To obtain evidence for possible mechanisms of the observed in vivo effects, the four glycoalkaloids (alpha-chaconine, alpha-solanine, solasonine and alpha-tomatine) mentioned above and the aglycones solanidine and tomatidine were also evaluated in in vitro assays for estrogenic activity. Only solanidine at 10 microM concentration exhibited an increase in the MCF-7 human breast cancer cell proliferation assay. Generally, the biological

    The pharmacokinetics and safety of hyperimmune anti-human immunodeficiency virus (HIV) intravenous immunoglobulin (HIVIG) were evaluated in the first 28 maternal-infant pairs enrolled in a randomized, intravenous immunoglobulin (IVIG)-controlled trial of HIVIG maternal-infant HIV transmission prophylaxis. Using 200 mg/kg, mean half-life and volume of distribution (Vd) in women were 15 days and 72 mL/kg, respectively, after one and 32 days and 154 mL/kg after three monthly infusions, with stable 4 mL/kg/day clearance. Transplacental passage occurred. Newborn single-dose half-life, Vd, and clearance were 30 days, 143 mL/kg, and 4 mL/kg/day, respectively. HIVIG rapidly cleared maternal serum immune complex-dissociated p24 antigen, and plasma HIV-1 RNA levels were stable. Mild to moderate adverse clinical effects occurred in 2 of 103 maternal and 2 of 25 infant infusions. No adverse hematologic, blood chemistry, or immunologic effects were seen. HIVIG is well-tolerated in HIV-infected pregnant women and their newborns, clears antigenemia, crosses the placenta, and exhibits pharmacokinetics similar to those of other immunoglobulin preparations.

    Reasoning well about risk is most challenging when a woman is pregnant, for patient and doctor alike. During pregnancy, we tend to note the risks of medical interventions without adequately noting those of failing to intervene, yet when it’s time to give birth, interventions are seldom questioned, even when they don’t work. Meanwhile, outside the clinic, advice given to pregnant women on how to stay healthy in everyday life can seem capricious and overly cautious. This kind of reasoning reflects fear, not evidence.

    This study report documents the development of a finite element (FE) model for analyzing trauma in pregnant women involved in road accidents and help the design of a specific safety device. The model is representative of a 50th percentile pregnant woman at 26 weeks of pregnancy in sitting position. To achieve this, the HUMOS 2 model, which has been validated in a wide range of dynamic tests, was scaled to the morphology of a woman in the 50th percentile and coupled with a model of gravid uterus. During scaling, special attention was paid to the pelvic region which is known to differ considerably in morphological terms between men and women. The gravid uterus model includes a placenta, a fetus, uterosacral ligaments and the amniotic fluid by means of fluid structure interaction formulation. The uterus and the female model were coupled using an original method whereby the growth of an uterus was simulated to compress the abdominal organs in a realistic manner. The model was validated based on experimental tests described in the literature. Additional tests based on abdominal loadings with a seatbelt on Post Mortem Human Surrogates (PMHS) coupled to silicone uterus were also performed. Results highlighted the role of the possible interaction of the fetus in the pregnant woman abdominal response. Experimental corridors taking into account the presence of this fetus could therefore be proposed.

    Rapid HIV test in labour provide an opportunity for the identification of HIV positive pregnant women who should benefit from interventions to reduce the risk of mother-to-child transmission (MTCT) of HIV. Between November 2013 and June 2014 we conducted rapid HIV testing of pregnant women in labour at the National Hospital Abuja to determine the HIV seroconversion rate in pregnancy and the prevalence of HIV in pregnant women in labour with previously unknown status. HIV testing and counseling (HTC) was acceptable to 224 (99.6%) of the pregnant women who met the study criteria. The mean 'turnaround' time for test result was 288 minutes and 16.2 minutes for tests performed in the hospital laboratory and those performed at the point-of-care (labour ward) respectively. HIV seroconversion was detected in 2(1.2%) of the 165 parturients with initial HIV negative result early in the index pregnancy. HIV infection was detected in four (2.7%) of the 59 parturients with unknown HIV status. Secondary school level education was significantly associated with HIV seroconversion in pregnancy P < 0.001. HTC in labour using rapid testing strategy is feasible and acceptable in our setting. The introduction of HCT will lead to the diagnosis of HIV positive women in labour, appropriate interventions and prevention of MTCT of HIV.

    As use of imaging in the evaluation of pregnant and lactating patients continues to increase, misperceptions of radiation and safety risks have proliferated, which has led to often unwarranted concerns among patients and clinicians. When radiologic examinations are appropriately used, the benefits derived from the information gained usually outweigh the risks. This review describes appropriateness and safety issues, estimated doses for imaging examinations that use iodizing radiation (ie, radiography, computed tomography, nuclear scintigraphy, and fluoroscopically guided interventional radiology), radiation risks to the mother and conceptus during various stages of pregnancy, and use of iodinated or gadolinium-based contrast agents and radiotracers in pregnant and lactating women. Maternal radiation risk must be weighed with the potential consequences of missing a life-threatening diagnosis such as pulmonary embolus. Fetal risks (ie, spontaneous abortion, teratogenesis, or carcinogenesis) vary with gestational age and imaging modality and should be considered in the context of the potential benefit of medically necessary diagnostic imaging. When feasible and medically indicated, modalities that do not use ionizing radiation (eg, magnetic resonance imaging) are preferred in pregnant and lactating patients. Radiologists should strive to minimize risks of radiation to the mother and fetus, counsel patients effectively, and promote a realistic understanding of risks related to imaging during pregnancy and lactation.

    Background Silver nanoparticles (AgNPs) have attracted much interest and have been used for antibacterial, antifungal, anticancer, and antiangiogenic applications because of their unique properties. The increased usage of AgNPs leads to a potential hazard to human health. However, the potential effects of AgNPs on animal models are not clear. This study was designed to investigate the potential impact of AgNPs on pregnant mice. Methods The synthesis of AgNPs was performed using culture extracts of Bacillus cereus. The synthesized AgNPs were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and transmission electron microscopy. AgNPs were administrated into pregnant mice via intravenous infusion at 1.0 mg/kg doses at 6.5 days postcoitum (dpc). At 13.5, 15.5, and 17.5 dpc, the pregnant mice were euthanized, and the embryo and placenta were isolated. The meiotic status of oocytes was evaluated. DNA methylation studies were performed, and aberrant imprinting disrupted fetal, placental, and postnatal development. Quantitative real-time polymerase chain reaction analysis and Western blot were used to analyze various gene expressions. Results The synthesized AgNPs were uniformly distributed and were spherical in shape with an average size of 8 nm. AgNPs exposure increased the meiotic progression of female germ cells in the fetal mouse ovaries, and maternal AgNP exposure significantly disrupted imprinted gene expression in 15.5 dpc embryos and placentas, such as Ascl2, Snrpn, Kcnq1ot1, Peg3, Zac1, H19, Igf2r, and Igf2; DNA methylation studies revealed that AgNPs exposure significantly altered the methylation levels of differentially methylated regions of Zac1. Conclusion The results from this study indicated that early exposure to AgNPs has the potential to disrupt fetal and postnatal health through epigenetic changes in the embryo and abnormal development of the placenta. These results can contribute to research involved in the safe use of

    Influenza A H1N1 is an acute respiratory illness caused by a new strain of H1N1. Human influenza is a subtype of influenza Avirus, from the family of Orthomyxoviridae. This strain is the cause of new influenza pandemic declared by the World Health Organization in June, 2009. This paper reports the first case occurred in Mexico: a 39-year-old woman with a history of diabetes mellitus type 2 and obesity grade II, which suffered atypical and aggressive pneumonia positive to coronavirus. Patient died 98 hours after her admission to the hospital unit. Due to the clinical presentation of the case, the doctors sent samples to the Instituto Nacional de Diagnóstico y Referencia Epidemiológica that sent an aliquot of the National Center for Immunization and Respiratory Diseases of theAgency of Public Health in Canada, that reported positivity to influenza virus, and catalogued it as a new global strain called influenza A virus H1N1. The notice of 229E/NL63 coronavirus and its relationship to the recent outbreaks of avian influenza in humans and the clinical presentation of the case were the epidemiological circumstances that prevented the nation epidemiology system to establish global containment strategies to prevent the spread of this emerging infection. The consequence was the declaration of WHO pandemic alert level 6. Its behavior in pregnancy, reported by Assistant General Direction of Epidemiology in Mexico, has placed this infection as a risk factor for women.

Results Six hundred forty-four transcripts from 633 known genes were differentially expressed (false discovery rate (FDR) <0.1; fold-change >1.5), while 42 exons from 36 genes showed differential usage (difference in FIRMA scores >2 and FDR<0.1) between the visceral and subcutaneous fat of pregnant women. Fifty-six known genes were differentially expressed between pregnant and non-pregnant subcutaneous fat and three genes in the visceral fat. Enriched biological processes in the subcutaneous adipose tissue of pregnant women were mostly related to inflammation. Conclusion The transcriptome of visceral and subcutaneous fat depots reveals pregnancy-related gene expression and splicing differences in both visceral and subcutaneous adipose tissue. Furthermore, for the first time, alternative splicing in adipose tissue has been associated with regional differences and human parturition. PMID:26636677

    A physiologically based pharmacokinetic (PBPK) model was developed to predict the concentration of flumioxazin, in the blood and fetus of pregnant humans during a theoretical accidental intake (1000 mg/kg). The data on flumioxazin concentration in pregnant rats (30 mg/kg po) was used to develop the PBPK model in pregnant rats using physiological parameters and chemical specific parameters. The rat PBPK model developed was extrapolated to a human model. Liver microsomes of female rats and a mixed gender of humans were used for the in vitro metabolism study. To determine the % of flumioxazin absorbed after administration at a dose of 1000 mg/kg assuming maximum accidental intake, the biliary excretion study of [phenyl-U-{sup 14}C]flumioxazin was conducted in bile duct-cannulated female rats (Crl:CD (SD)) to collect and analyze the bile, urine, feces, gastrointestinal tract, and residual carcass. The % of flumioxazin absorbed at a dose of 1000 mg/kg in rats was low (12.3%) by summing up {sup 14}C of the urine, bile, and residual carcass. The pregnant human model that was developed demonstrated that the maximum flumioxazin concentration in the blood and fetus of a pregnant human at a dose of 1000 mg/kg po was 0.86 μg/mL and 0.68 μg/mL, respectively, which is much lower than K{sub m} (202.4 μg/mL). Because the metabolism was not saturated and the absorption rate was low at a dose of 1000 mg/kg, the calculated flumioxazin concentration in pregnant humans was thought to be relatively low, considering the flumioxazin concentration in pregnant rats at a dose of 30 mg/kg. For the safety assessment of flumioxazin, these results would be useful for further in vitro toxicology experiments. - Highlights: • A PBPK model of flumioxazin in pregnant humans was developed. • Simulated flumioxazin concentration in pregnant humans was relatively low. • The results would be useful for further in vitro toxicology experiments.

    We have investigated the prevalence of antibodies against Toxoplasma gondii, Trypanosoma cruzzi, Hepatitis B virus, cytomegalovirus, rubella virus, and human immunodeficiency virus in 139 adolescent pregnant women and in their high risk newborn children. The methods employed were the Sabin and Feldman reaction, complement fixation reaction, ELISA, and xenodiagnostic 30.9% of the pregnant group were seropositive for T. gondii, both mothers and newborns were IgM-negative. Two mothers (1.4%) presented anti T. cruzii antibodies, and one newborn child had circulating parasites. Related to the virological studies, 93.5% of the population were anti CMV antibodies positive and all their newborns were IgM (-) 90.6% of the adolescents were rubella positive and one was seropositive to VIH. We conclude that the prevalence found in this group of adolescent pregnant women are not significantly different to the one reported for the general pregnant women population.

    Despite the fact that obesity is a major risk factor for preeclampsia (PE), the pathophysiological mechanisms whereby obesity and metabolic factors such as leptin increase this risk are unclear. While human data have shown that hyperleptinemia is associated with PE, the long-term effect of hyperleptinemia on blood pressure during pregnancy is unknown. Thus we tested the hypothesis whether chronic circulating leptin elevations in pregnant rats increase blood pressure and placental factors known to play a role in PE. On gestational day (GD)14, rats were assigned to the normal pregnant group with food intake ad libitum (control), leptin-treated (0.5 μg·kg(-1)·min(-1) ip) pregnant group with food intake ad libitum (pregnant+LEP), and normal pregnant group with food intake adjusted to the food intake of pregnant+LEP rats (pregnant-FR). On GD19, mean arterial pressure (MAP) was assessed and tissues were collected. Serum leptin concentration was elevated in pregnant+LEP compared with control and pregnant-FR (18.0 ± 2.8 vs. 0.8 ± 0.1 vs. 0.3 ± 0.1 ng/ml; P < 0.05), which was associated with increased MAP (121.3 ± 8.1 vs. 102.4 ± 2.4 vs. 101.3 ± 1.8 mmHg; P < 0.05). Food intake and body weight were reduced in pregnant+LEP and pregnant-FR by the end of gestation. Additionally, placentas and fetuses of these groups were lighter than those of control. However, placental expression of tumor necrosis factor-α was significantly greater in pregnant+LEP compared with controls (1.6 ± 0.1 vs. 1.1 ± 0.1 pg/mg; P < 0.05). In conclusion, leptin increases blood pressure and placental tumor necrosis factor-α during pregnancy despite its effect of reducing food intake and body weight, and represents a mechanism whereby obesity can promote the development of hypertension in PE.

    The epidemiologic and sociodemographic characteristics of human deficiency virus (HIV) infection vary from one country to another. The objective of this study was to determine the prevalence of HIV infection in pregnant women in Dakar and associated factors. Systematic anonymous screening was performed in pregnant women admitted to the maternity ward. Women whose seropositivity was confirmed by Western blot retroviral serology were included. One woman out of four was assigned by simple random selection to the case control group. Over a 24 month period, 12,498 women were tested. 104 were seropositive (44 HIV1, 58HIV2, and 2 HIV1-HIV2 giving a prevalence of 0.8%. Factors associated with HIV1 and HIV2 were different: mean age 21.7 years for HIV1 versus 30.6 for HIV 2 (p = 0.05); origin in Guinea-Bissau for HIV2 (p = 0.001); mean number of pregnancies 2.6 for HIV1 versus 5.9 for HIV2 (p = 0.001); mean parity 1.5 for HIV1 versus 4.5 for HIV2 (p < 0.01); vitality of the conception product in 85.1% for HIV2 versus 67.5% for HIV1 (p = 0.0001). These data confirm the low prevalence of HIV infection in pregnant women, with a predominance for HIV2. The factors identified in associated with virus type suggest a different mode of transmission and/or reduced virulence or HIV2 compared with HIV1. Knowledge of these factors helps orient management strategies, especially in pregnant women.

    Clinical pharmacology studies that describe the pharmacokinetics and pharmacodynamics of drugs in pregnant women are critical for informing on the safe and effective use of drugs during pregnancy. That being said, multiple factors have hindered the ability to study drugs in pregnant patients. These include concerns for maternal and fetal safety, ethical considerations, the difficulty in designing appropriate trials to assess the study objectives, and funding limitations. This document summarizes the recommendations of a panel of experts convened by the Division of Microbiology and Infectious Diseases at the National Institute of Allergy and Infectious Diseases, National Institutes of Health. These experts were charged with reviewing the issues related to the development of preclinical and clinical drug studies in pregnant women and to develop strategies for addressing these issues. These findings may also be utilized in the development of future drug studies involving pregnant women and their fetus/neonate. PMID:25425722

    2014-01-01

    Background: Investigations across the world confirm dramatic increment in the use of complementary and alternative medicine in pregnant women. The most important aspect is lack of awareness of pregnant women about potential effects of using traditional medicine on fetus; some herbal products may be teratogenic in human and animal models. In this area, so far, no research has been conducted in Ethiopia to assess traditional medicine use in pregnant women. Objectives: Therefore, the main objective of this study was to investigate the prevalence and use of herbal drugs among pregnant women attending Nekemte Hospital to provide baseline information for future studies. Patients and Methods: A cross-sectional descriptive study was conducted by quantitative and qualitative approaches to identify the prevalence of using herbal medicines among pregnant women. About 50.4% of study participants used herbal drugs during their pregnancy. The proportion of herbal drug usage was gradually decreased along with the first, second and third trimesters of pregnancy. The most and least commonly used herbs were ginger (44.36%) and tenaadam (9.15 %), respectively. The common indications of herbal remedies use during pregnancy were nausea (23.90%) and morning sickness (21.05%). Results: The result of the present study confirmed wide use of herbal drugs use during pregnancy that need to report the safety concerns of these drugs during pregnancy. Conclusions: To achieve the requirements of pregnant women, it is vital for health care workers to be familiar with the effect of herbal medicine in pregnancy. PMID:25625049

  13. Immunohistochemical localization of specific relaxin-binding cells in the cervix, mammary glands, and nipples of pregnant rats.

    Previously, we demonstrated that endogenous circulating relaxin promotes the growth and softening of the cervix, the development of the mammary glands, and the growth and development of nipples. Due to the remarkably similar modifications in the histological appearance of the extracellular matrix in the cervix, mammary glands, and nipples, we hypothesized that there may be a common mechanism(s) of action of relaxin in these tissues. A fundamental step toward understanding this mechanism is to identify specific cells that contain relaxin receptors, that is to identify those cells that initiate relaxin's effects within relaxin target tissues. To identify specific relaxin-binding cells in the cervix, mammary glands, and nipples of the pregnant rat, a biologically active biotinylated relaxin probe was prepared. This probe for putative relaxin receptors was administered to intact rats on day 18 of pregnancy. After 1 h, the animals were killed, and tissues were fixed by immersion in 4% paraformaldehyde for 10 h. Fixed tissues were rinsed in 0.1 M phosphate buffer (pH 7.4) and cryoprotected in an ascending series of 5%, 10%, and 20% sucrose solutions. The tissues were frozen in Tissue-Tek O.C.T. compound and stored at -70 C until sectioning. Frozen sections (12 microns) were cut on a Tissue Tek II cryostat at -24 C and thaw mounted on slides coated with 0.01% poly-l-lysine (mol wt, 300-6000). The biotinylated relaxin was localized in cryosections with an antibiotin immunoglobulin G conjugated to colloidal gold, which was subsequently visualized for light microscopy with silver intensification. Specific binding of the biotinylated relaxin was localized in the epithelial and smooth muscle cells of the cervix, the epithelial cells of the mammary glands, and the epithelial cells, smooth muscle cells, and skin of the nipples. We conclude that those cells exhibiting specific relaxin binding probably contain relaxin receptors and, therefore, mediate relaxin's effects in these

    The beta 2-sympathomimetic drug fenoterol (fenoterol hydrobromide, CAS 1944-12-3, Partusisten) is routinely used to inhibit uterine contractions (tocolysis). Investigations of plasma concentrations of those receiving i.v. or oral tocolysis often show different results, both within particular groups of pregnant women and in comparison with non-pregnant persons. The aim of this study was to determine the pharmacokinetics of fenoterol in pregnant women, an important factor which so far had not been known. Four healthy pregnant women with similar weight and gestational age and all with premature labor were administered a continuous intravenous infusion of 4 micrograms fenoterol/min. During and up to 24 hours after the end of the infusion, venous blood samples were taken in order to determine the fenoterol plasma concentrations by radioimmunoassay. From a steady state concentration (css) of 2242 +/- 391 pg/ml (x +/- S.E.), a non-linear two-phased plasma elimination was seen with half-lives t1/2 of 11.40 min and 4.87 h. The area under the plasma concentration-time curve (AUC0-12h) was 6.27 ng/ml x h. The total clearance (Cltot) was 114.8 l/h. These data are nearly the same as the data already known for healthy non-pregnant (male) volunteers. The deviations which are seen in the plasma concentrations in pregnant women in comparison to non-pregnant persons during or after continuous i.v. infusion can therefore not be caused by differences in the pharmacokinetics. Other factors, however, such as body weight and/or gestational age, might influence the results.

    Bisphenol A (BPA) is a weakly estrogenic monomer used to produce polymers for food contact and other applications, so there is potential for oral exposure of humans to trace amounts via ingestion. To date, no physiologically based pharmacokinetic (PBPK) model has been located for BPA in pregnant mice with or without fetuses. An estimate by a mathematical model is essential since information on humans is difficult to obtain experimentally. The PBPK model was constructed based on the pharmacokinetic data of our experiment following single oral administration of BPA to pregnant mice. The risk assessment of bisphenol A (BPA) on the development of human offspring is an important issue. There have been limited data on the exposure level of human fetuses to BPA (e.g. BPA concentration in cord blood) and no information is available on the pharmacokinetics of BPA in humans with or without fetuses. In the present study, we developed a physiologically based pharmacokinetic (PBPK) model describing the pharmacokinetics of BPA in a pregnant mouse with the prospect of future extrapolation to humans. The PBPK model was constructed based on the pharmacokinetic data of an experiment we executed on pregnant mice following single oral administration of BPA. The model could describe the rapid transfer of BPA through the placenta to the fetus and the slow disappearance from fetuses. The simulated time courses after three-time repeated oral administrations of BPA by the constructed model fitted well with the experimental data, and the simulation for the 10 times lower dose was also consistent with the experiment. This suggested that the PBPK model for BPA in pregnant mice was successfully verified and is highly promising for extrapolation to humans who are expected to be exposed more chronically to lower doses.

    The objective of this study was to provide specific characteristics of injuries and crash characteristics for pregnant occupants from the National Automotive Sampling System/Crashworthiness Data System (NASS/CDS) database for pregnant women as a group, broken down by trimester, and compared to non-pregnant women. Using all NASS/CDS cases collected between the years 2000 and 2012 with at least one pregnant occupant, the entire pregnant data set included 321,820 vehicles, 324,535 occupants, and 640,804 injuries. The pregnant occupant data were compared to the characteristics of NASS/CDS cases for 14,719,533 non-pregnant females 13-44 years old in vehicle crashes from 2000 to 2012. Sixty five percent of pregnant women were located in the front left seat position and roughly the same percentage of pregnant women was wearing a lap and shoulder belt. The average change in velocity was 11.6 mph for pregnant women and over 50% of crashes for pregnant women were frontal collisions. From these collisions, less than seven percent of pregnant women sustained MAIS 2+ injuries. Minor differences between the pregnant and non-pregnant occupants were identified in the body region and source of injuries sustained. However, the data indicated no large differences in injury or crash characteristics based on trimester of pregnancy. Moreover, the risk of an MAIS 2+ level injury for pregnant occupants is similar to the risk of injury for non-pregnant occupants based on the total vehicle change in velocity. Overall this study provides useful data for researchers to focus future efforts in pregnant occupant research. Additionally, this study reinforces that more detailed and complete data on pregnant crashes needs to be collected to understand the risk for pregnant occupants.

    To discriminate between primary (PI) and remote (RI) human cytomegalovirus (HCMV) infection, several immunological parameters were monitored for a 2-year period in 53 pregnant women with PI, and 33 pregnant women experiencing HCMV PI at least 5 years prior. Cytokine (IFN-γ and IL-2) production by and phenotype (effector/memory CD45RA(+)) of HCMV-specific CD4(+) and CD8(+) T-cells as well as the lymphoproliferative responses (LPR) were evaluated, with special reference to the comparison between a group of women transmitting (T) and a group of non-transmitting (NT) the infection to fetus. While HCMV-specific CD4(+) T-cells reached at 90 days post-infection (p.i.) values comparable to RI, CD8(+) T-cells reached at 60 days p.i. levels significantly higher and persisting throughout the entire follow-up. Instead, IL-2 production and lymphoproliferative responses were lower in PI than RI for the entire follow-up period. Effector memory CD45RA(+) CD4(+) and CD8(+) HCMV-specific T-cells increased until 90 days p.i., reaching and maintaining levels higher than RI. The comparison between T and NT women showed that, at 30 days p.i., in NT women there was a significantly higher IL-2 production by HCMV-specific CD4(+) T-cells, and at 60 days p.i. a significantly higher frequency of both specific CD4(+) and CD8(+) CD45RA(+) T-cells. HCMV T-cell response appears to correlate with virus transmission to fetus and some parameters (CD4(+) lymphoproliferation, and frequency of HCMV-specific CD8(+) IL2(+) T-cells) may help in dating PI during pregnancy.

    Disasters are natural or man-made life-altering events that require preplanning to save lives. Pregnant women are a particularly vulnerable population in such events, because they have special physical and psychosocial needs. Preparations made for labor and birth might have to be drastically altered in the event of an emergency, especially if a woman is separated from her familiar healthcare providers and facilities. The issue of breastfeeding also must be considered in disaster planning for pregnant women, along with occurrences such as food shortages and outbreak of illnesses caused by overcrowding of displaced persons. Recent events such as hurricane Katrina have demonstrated that maternal/child nurses need to become more aware of disaster planning and help to empower pregnant women with knowledge of how to handle their special needs in times of crisis.

    This work uses cartography as a method for mapping the trajectory of primary healthcare provided to pregnant women. The scope of the study comprises 9 Basic Healthcare Units located in the city of Juazeiro do Norte in the State of Ceará. In all, fifteen women in the 37th to 39th week of pregnancy were selected. Interviews were conducted with these women during the period from January to June 2010. The cartographic findings were depicted in stages in the flowchart, which exposed lacunas in prenatal healthcare, such as the low number of oncotic cytology exams conducted and the lack of educational counseling. Nevertheless, in the interviews, a significant number of pregnant women expressed satisfaction with the prenatal care provided. The good relationships developed between the healthcare professionals and the pregnant women were the main reason that led them to continue the treatment. This fact reinforces the importance of dialogue between these two actors for the success of prenatal healthcare.

    Stroke during pregnancy is rare, but after occurring, most patients develop serious neurological conditions. Hemorrhagic stroke, including intracerebral hemorrhage and subarachnoid hemorrhage, often requires emergency surgical intervention. In addition to significant maternal physiological changes, the potential for fetal harm should be considered during anesthetic management of these patients. Whether cesarean section or neurosurgical intervention should be prioritized or performed simultaneously in pregnant women with stroke is an important issue. Whether the patients receive general or spinal and epidural anesthesia is another clinically significant issue. Finally neurosurgeons, anesthesiologists, and obstetricians should cooperate to manage pregnant women with stroke.

    QUESTION: One of my patients is planning pregnancy and has started taking multivitamin supplements. She is experiencing gastric discomfort. What are the alternatives? ANSWER: Gastric discomfort is usually related to iron intake; pregnant women could use supplements with less iron. Pregnant women need 0.4 to 1.0 mg of folic acid daily. If they have a family history of neural tube defects (NTDs), insulin-dependent diabetes mellitus, or epilepsy, or are currently taking valproic acid, carbamazepine, or antifolates (eg, sulfonamides), they are at intermediate-to-high risk of having babies with NTDs and need 4.0 to 5.0 mg of folic acid daily.

    Hepatitis C virus (HCV) affects about 3% of the world's population, with the highest prevalence in individuals under 40. The prevalence in pregnant women varies with geographical distribution (highest in developing countries). Prevalence also increases in sub-populations of women at high risk for blood-transmitted infections. HCV infection in pregnancy represents a non-negligible problem. However, most of the past antiviral regimens cannot be routinely offered to pregnant or breastfeeding women because of their side effects. We briefly reviewed the issue of treatment of HCV infection in pregnant/breastfeeding women focusing on the effects of the new direct-acting antivirals on fertility, pregnancy and lactation in animal studies and on the potential risk for humans based on the pharmacokinetic properties of each drug. Currently, all new therapy regimens are contraindicated in this setting because of lack of sufficient safety information and adequate measures of contraception are still routinely recommended for female patients of childbearing potential.

  4. Heat produces uteroplacental circulatory disturbance in pregnant rats through action of corticotropin releasing hormone (CRH).

    2000-01-01

    There is some evidence showing an existence of corticotropin releasing hormone (CRH) and opioid peptides, including beta-endorphin (betaEP), in human placenta, whereas physiological roles of the placental peptides in response to stress remain to be elucidated. To clarify the involvement of CRH and opioid system in the uteroplacental circulation in the pregnant rats exposed to heat, we examined the effects of heat and intravenous administration of CRH receptor antagonist alpha-helical CRH (9-41) on the uteroplacental blood flow, as well as blood CRH, and blood and placental betaEP in pregnant rats. Heat did not change uterine blood flow in virgin rats, but reduced uteroplacental blood flow in pregnant rats. The reduced uteroplacental blood flow induced by heat in pregnant rats was reversed by the administration of alpha-helical CRH. Independent of the status of pregnancy, heat increased blood CRH, which was not reversed by alpha-helical CRH. Although heat did not change placental betaEP, alpha-helical CRH reduced blood and placenta betaEP in pregnant rats. These results suggest that the uteroplacental circulatory disturbance caused by heat is mediated by CRH, possibly through the involvement of CRH receptor in rat placenta. The placental opioid system seems unlikely to be involved in the mediation of uteroplacental circulation.

    Preeclampsia is a common disease of pregnancy characterised by maternal hypertension and proteinuria. Abnormal placentation in early pregnancy and abnormal cytokine and anti-angiogenic factor expression are thought to contribute to the clinical syndrome of endothelial dysfunction evident in the second half of gestation. The mechanisms underlying both the placental pathology and its translation to the maternal clinical syndrome are not fully understood. A model of preeclampsia manifest by clinically evident endothelial dysfunction (increased blood pressure and proteinuria) was induced by administration of low-dose TNF-α for 2weeks at mid-gestation in pregnant baboons (Papio hamadryas). Blood pressure was monitored continuously and remotely by intra-arterial radiotelemetry. Following TNF-α infusion, there was an increase in systolic and diastolic blood pressure and development of proteinuria in pregnant treated animals, but not in pregnant saline controls nor in non-pregnant TNF-α treated animals. The treated pregnant animals also developed elevated plasma soluble FMS-like tyrosine kinase-1 (sFLT-1) and increased placental mRNA expression of sFLT-1 and soluble endoglin (sEng). These results clearly demonstrate that the cytokine TNF-α can induce the clinical and biochemical features of human preeclampsia. The results identify a link between cytokines, placental dysfunction and endothelial dysfunction resulting in a loss of maternal blood pressure control.

    Exposure to antibiotics during pregnancy can pose a systematic effect on human health. A few bio-monitoring studies have demonstrated an extensive exposure of children to antibiotics, but there is still lack of data for pregnant women. To assess the exposure of pregnant women to antibiotics and potential health risk, we investigated 536 pregnant women aged 16-42 years from two geographically different study sites in Eastern China in 2015. We measured 21 antibiotics of five categories (seven fluoroquinolones, three phenicols, four tetracyclines, three macrolides, and four sulfonamides) in urines by using the isotope dilution ultra-performance liquid chromatography coupled to quadrupole time of-flight mass spectrometry. Hazard index (HI) was calculated based on estimated daily exposure dose and acceptable daily intakes. Sixteen antibiotics were found in urines with detection frequencies between 0.2% and 16.0%. Antibiotics were overall detected in 41.6% of urines, and two or more antibiotics were detected in 13.1% of urines. Ciprofloxacin, ofloxacin, and trimethoprim were most frequently detected in urine with detection frequencies between 10% and 20%. The majority of the antibiotics tested had an estimated daily exposure dose less than 1μg/kg/day and 4.3% of pregnant women had a HI value more than one. These findings indicated that pregnant women were frequently exposed to antibiotics and some individuals were in the potential risk of adverse microbiological effects induced by antibiotics.

    Ethical and human rights concerns have been expressed regarding the global shift in policies on HIV testing of pregnant women. The main purpose of this research was to conduct a policy analysis using a human rights-based approach of national policies for HIV testing of pregnant women. We collected HIV testing policies from 19 countries including: Cambodia, China, Guyana, Haiti, India, Jamaica, Kenya, Moldova, Papua New Guinea, Russian Federation, South Africa, Sudan, Swaziland, Tanzania, Ukraine, United States, Uzbekistan, Zambia and Zimbabwe. We analysed the HIV testing policies using a standardised framework that focused on government obligations to respect, protect and fulfil. Our results highlight the need for more attention to issues of pregnant women's autonomy in consenting to HIV testing, confidentiality in antenatal care settings and provision of counselling and care services. We conclude with a discussion about potential implications of the current testing policies and provide recommendations for ways that HIV testing policies can more effectively uphold the human rights of pregnant women.

    For the first time, a population approach was used to describe abacavir (ABC) pharmacokinetics in HIV-infected pregnant and nonpregnant women. A total of 266 samples from 150 women were obtained. No covariate effect (from age, body weight, pregnancy, or gestational age) on ABC pharmacokinetics was found. Thus, it seems unnecessary to adapt the ABC dosing regimen during pregnancy.

    Muscle sympathetic nerve activity is increased during normotensive pregnancy while mean arterial pressure is maintained or reduced, suggesting baroreflex resetting. We hypothesized spontaneous sympathetic baroreflex gain would be reduced in normotensive pregnant women relative to nonpregnant matched controls. Integrated muscle sympathetic burst incidence and total sympathetic activity (microneurography), blood pressure (Finometer), and R-R interval (ECG) were assessed at rest in 11 pregnant women (33 ± 1 wk gestation, 31 ± 1 yr, prepregnancy BMI: 23.5 ± 0.9 kg/m2) and 11 nonpregnant controls (29 ± 1 yr; BMI: 25.2 ± 1.7 kg/m2). Pregnant women had elevated baseline sympathetic burst incidence (43 ± 2 vs. 33 ± 2 bursts/100 heart beats, P = 0.01) and total sympathetic activity (1,811 ± 148 vs. 1,140 ± 55 au, P < 0.01) relative to controls. Both mean (88 ± 3 vs. 91 ± 2 mmHg, P = 0.4) and diastolic (DBP) (72 ± 3 vs. 73 ± 2 mmHg, P = 0.7) pressures were similar between pregnant and nonpregnant women, respectively, indicating an upward resetting of the baroreflex set point with pregnancy. Baroreflex gain, calculated as the linear relationship between sympathetic burst incidence and DBP, was reduced in pregnant women relative to controls (−3.7 ± 0.5 vs. −5.4 ± 0.5 bursts·100 heart beats−1·mmHg−1, P = 0.03), as was baroreflex gain calculated with total sympathetic activity (−294 ± 24 vs. −210 ± 24 au·100 heart beats−1·mmHg−1; P = 0.03). Cardiovagal baroreflex gain (sequence method) was not different between nonpregnant controls and pregnant women (49 ± 8 vs. 36 ± 8 ms/mmHg; P = 0.2). However, sympathetic (burst incidence) and cardiovagal gains were negatively correlated in pregnant women (R = −0.7; P = 0.02). Together, these data indicate that the influence of the sympathetic nervous system over arterial blood pressure is reduced in normotensive pregnancy, in terms of both long-term and beat-to-beat regulation of arterial pressure

    Recent literature suggests that exposure to low concentrations of heavy metals may affect both maternal and child health. This study aimed to determine the biological heavy metals concentrations of pregnant women as well as environmental and dietary factors that may influence exposure concentrations. One hundred and seventy three pregnant women were recruited from Western Australia, each providing a sample of blood, first morning void urine, residential soil, dust and drinking water samples. Participants also completed a questionnaire which included a food frequency component. All biological and environmental samples were analysed for heavy metals using ICP-MS. Biological and environmental concentrations of lead and mercury were generally low (Median Pb Drinking Water (DW) 0.04 µg/L; Pb soil <3.0 µg/g; Pb dust 16.5 µg/g; Pb blood 3.67 µg/L; Pb urine 0.55; µg/L Hg DW <0.03; Hg soil <1.0 µg/g; Hg dust <1.0 µg/g; Hg blood 0.46 µg/L; Hg urine <0.40 µg/L). Cadmium concentrations were low in environmental samples (Median CdDW 0.02 µg/L; Cdsoil <0.30 ug/g; Cddust <0.30) but elevated in urine samples (Median 0.55 µg/L, creatinine corrected 0.70 µg/g (range <0.2–7.06 µg/g creatinine) compared with other studies of pregnant women. Predictors of increased biological metals concentrations in regression models for blood cadmium were residing in the Great Southern region of Western Australia and not using iron/folic acid supplements and for urinary cadmium was having lower household annual income. However, these factors explained little of the variation in respective biological metals concentrations. The importance of establishing factors that influence low human exposure concentrations is becoming critical in efforts to reduce exposures and hence the potential for adverse health effects. -- Highlights: • Biological heavy metals concentrations in women in their 3rd trimester of pregnancy. • Exposure assessment including environmental, lifestyle and activity

    Proper nutrition during gestation is important to prevent adverse pregnancy outcomes. Eggs contain many important nutrients necessary for fetal development and human survival. Three focus groups were conducted with Latina women living in Connecticut to identify cultural beliefs toward egg consumption during pregnancy, traditional egg dishes, and methods of preparation. A cross-sectional study was then carried out with a sample of predominately Puerto Rican pregnant Latinas (N = 241) to identify the frequency of consumption of eggs and egg-containing dishes as well as methods of preparation using a tailored food frequency questionnaire modified for this population. Paired sample t-tests were used to examine if there were differences in weekly mean egg intake patterns between the year prior to the pregnancy and during pregnancy based on a Food Frequency Questionnaire. Women were categorized into eggs consumers and non-consumers if they consumed or did not consume eggs during the previous day based on 24-hour recall data. Independent-sample t-test and chi-square cross-tabulation analyses were conducted to examine the association between egg consumption and nutrient intake categories. Results showed that eggs and egg-containing traditional dishes are consumed by Latinas before and during pregnancy. Egg consumers had higher intakes of protein, fat, vitamin K, vitamin E, selenium, beta carotene, lutein and zeaxanthin, cholesterol, total polyunsaturated fatty acids, and docosahexaenoic acid. Eggs contribute significantly to the diet of pregnant Latinas. PMID:21883065

    Objective: The rates of seropositivity, seroconversion and fetal infection with human cytomegalovirus were analyzed in pregnant women and newborn cord blood in this study. The relationships between maternal age, parity, cytomegalovirus serology and polymerase chain reaction results were evaluated. Materials and Methods: A total of 217 pregnant women attended our pregnancy clinic between April 2004 and October 2005. During each trimester, 5 cc of maternal blood was obtained and 5 cc of cord blood was collected after birth. An enzyme-linked immunosorbent assay (ELISA) was used to assess these samples for the presence of human cytomegalovirus protein pp65 antigen (in leukocytes) and cytomegalovirus DNA (in plasma). Results: The mean age of the pregnant women in our study was 28.1±5.3 years. No seroconversion was observed. Among the pregnant women, 212 (97.7%) were IgG positive, and 29 (13.4%) were IgM positive. Five of the pregnant women were positive for IgM alone (2.3%), whereas 24 (11.3%) were positive for both IgM and IgG. The 29 IgM-positive patients were reevaluated using the polymerase chain reaction, and no seropositivity was found. None of the cord blood samples were IgM positive, whereas 211 (97.3%) were IgG positive. There was no significant correlation between parity and seropositivity (p=0.487). The relationship between human cytomegalovirus seropositivity and maternal age was evaluated by dividing the pregnant women into two groups, with a cut-off age of 35 years. There was a significant difference in seropositivity between these two groups (p=0.045). Conclusion: Clearly, there is no need to screen pregnant women for Human cytomegalovirus (HCMV) in the Malatya region. Confirming serology results using the polymerase chain reaction and antigenemia testing to detect false positive results offers the advantage of avoiding unnecessary invasive interventions.

    The aims of this study were to identify dental caries and gingivitis among pregnant women, and to compare it with those in non-pregnant women in Chiang Mai, Thailand. Data were collected from 197 women (94 pregnant and 103 non-pregnant) from June to August, 2008. Dental caries and gingivitis was defined clinically according to the World Health Organization (WHO) diagnostic criteria. Over 74.0% of pregnant women had caries, and 86.2% had gingivitis. There were significant differences between pregnant and non-pregnant women with regard to dental caries (p < 0.001) and gingivitis (p = 0.021). The pregnant women were 2.9 times more likely to suffer from dental caries (95% confidence intervals (CI), 1.6-5.4), and 2.2 times more (95% CI, 1.1-4.7) from gingivitis compared to non-pregnant women. Farmers (Odd ratio (OR), 7.0; 95% CI, 1.8-26.3), high school graduation (OR, 3.0; 95% CI, 1.2-7.3), and universal health insurance coverage (OR, 2.1; 95% CI, 1.0-4.3) were significant predictors for gingivitis. Only high school graduates were found to be significant predictors of dental caries with an OR of 2.8 (95% CI, 1.2-6.3). Poor oral hygiene (OR, 2.2; 95% CI, 0.8-6.5), lack of knowledge (OR, 2.0; 95% CI, 0.6-6.3), and poor oral hygiene habits (OR, 3.0; 95% CI, 1.1-8.6) were important risk factors for dental caries. Similarly, inadequate oral hygiene status (OR, 24.8; 95% CI, 5.5-112.2), and poor oral health habits (OR, 5.2; 95% CI, 1.1-25.2) were found to be significant risk factors for gingivitis among pregnant women indicating, that most women should be trained in proper oral hygiene practices. Community awareness programs should be conducted to increase women's awareness of such hygienic practices.

    Oral naltrexone is used to treat alcohol and heroin dependence but is associated with poor patient compliance. Sustained-release preparations have been developed to overcome noncompliance. Many sustained-release preparations are composed of polymers combined with naltrexone. Limited data indicate that polymers induce variable levels of tissue reactivity and that naltrexone may increase this effect. A slow-release subcutaneous naltrexone-poly (DL-lactide) implant is currently being trialed to treat heroin dependence in Western Australia. A minority of women fall pregnant and, although tissue reactivity in nonpregnant humans is relatively minor, detailed chronological data during pregnancy are lacking. Histological changes in pregnant rats were assessed; a single active tablet containing poly[trans-3,6-dimethyl-1,4-dioxyane-2,5-dione] (DL-lactide) loaded with 25 mg of naltrexone was implanted subcutaneously, and tissue response was compared with inactive polymer implantation. Rats were timed mated at 13-26 days postimplant. Tissue assessment up to 75 days by a pathologist showed that naltrexone induced chronic inflammatory response in a dose-dependent manner, although still at a low level. Furthermore, for inactive implants, minimal foreign body reaction and fibrosis, together with low-level inflammation, suggested good long-term biocompatibility. We conclude that the Australian naltrexone-poly(DL-lactide) implant is tolerated in pregnant rats, reinforcing its potential role for managing alcohol and heroin dependence in pregnant humans.

    Case reports of 16 crashes involving pregnant occupants are presented that illustrate the main conclusions of a crash-investigation program that includes 42 crashes investigated to date. Some unusual cases that are exceptions to the overall trends are also described. The study indicates a strong association between adverse fetal outcome and both crash severity and maternal injury. Proper restraint use, with and without airbag deployment, generally leads to acceptable fetal outcomes in lower severity crashes, while it does not affect fetal outcome in high-severity crashes. Compared to properly restrained pregnant occupants, improperly restrained occupants have a higher risk of adverse fetal outcome in lower severity crashes, which comprise the majority of all motor-vehicle collisions.

    The Army Medical Services are responsible for promoting health in the military workplace. A survey of the potential health risks in the workplace to British Army servicewomen who are pregnant, or who breastfeed, was carried out. It was found that there was a total of 30 major workplace hazards to pregnant or breastfeeding servicewomen, and that medical guidance in this area was lacking. A Medline literature search on these hazards, was compiled, and an overview of the nature and extent of the military problem, together with a brief policy recommendation applying to each hazard. Guidelines based on these recommendations were distributed to primary care and obstetric unit medical officers in all three Armed Services. It is intended that the guidelines will assist Service doctors in giving informed advice on the avoidance of military occupational risks to pregnancy and to lactation.

    This study demonstrates the normal technetium-99m diethylenetriaminepentaacetic acid ((/sup 99m/Tc)DTPA) renal scan in pregnant patients with transplanted kidneys. Five pregnant renal transplant patients had seven (/sup 99m/Tc)DTPA renal studies to assess allograft perfusion and function. All scans showed the uteroplacental complex. The bladder was always compressed and distorted. The transplanted kidney was frequently rotated to a more vertical position. In all patients allograft flow and function were maintained. There was calyceal retention on all studies and ureteral retention activity in three of five patients. Using the MIRD formalism, the total radiation absorbed dose to the fetus was calculated to be 271 mrad. This radiation exposure is well within NRCP limits for the fetus of radiation workers and an acceptable low risk in the management of these high risk obstetric patients.

    Aiming at getting to know the work of nurses concerning pregnant adolescents, we have opted to develop a study to identify the characteristics of scientific production made by nurses about adolescence pregnancy by means of national and international indexed articles, between 1996 and 2000. The bibliographic survey resulted in a sample of 27 indexed articles. The participation of nurses in assisting pregnant adolescents is highlighted by taking part in adolescence pregnancy prevention programs, by assisting in the gravidic-puerperal period and by providing social support. As possibilities of participation for nurses, we have identified the important role of sexual education and adolescence pregnancy prevention programs, prenatal and post-delivery assistance programs. Also, we have emphasized the need to organize the nurse's work to facilitate access to contraceptive methods and to prevent sexually transmissible diseases.

    ABSTRACT Background: Women’s empowerment programs during pregnancy focus primarily on increasing women’s health goals and psychological empowerment has been considered important in most issues related to pregnant mothers’ mental health. Using path analysis, this study aims to examine the direct and indirect components of psychological empowerment of pregnant mothers. Methods: This model-testing study was conducted in Gorgan, northwest of Iran during three months in spring of 2015. Through random cluster sampling, a total number of 160 pregnant women were selected from 10 urban medical centers and clinics as primary centers. We used Spritzer’s Psychological empowerment scale. Suitable sampling based on Nunally and Bernstein was followed in the model. The relationships between the dependent variables were then examined by means of path analysis using Amos 18. Results: The psychological empowerment of pregnant mothers (PEPW) model is impacted by individual factors, such as marriage age and employment, including some subjectively rated factors such as marital satisfaction and experience of violence. The PEPW model was deemed appropriate as optimum conditions indicators of goodness of fit; low index of χ2/df shows little difference between the conceptual model and observed data, while RMSEA value indicated the goodness of fit. Other indicators such as CMIN=0.957, CMIN/DF=0.957, P-CLOSE=0.418, χ2=0.957 and probability level=0.328 the fact that the model is ideal. The mothers’ employment had the highest coefficient in the PEPW path model .731 (0.443, 0.965) bootstrap confidence intervals by 95%, and with a p-value of less than 0.05. Conclusions: The mothers’ employment is the most important factor in psychological empowerment, but it cannot be addressed quickly. Programming to increase marital satisfaction followed by a decrease in family violence and prevention of early marriage are necessary for promotion of psychological empowerment during pregnancy.

    Pain of lumbosacral segment of the vertebral column and the pelvis concerns about 45% of all pregnant women. The change of the body posture during pregnancy is the result of gravity centre relocation, which affects the musculosceletal system. Development of the joint, ligament and myofascial dysfunctions, as well as the pain in the lumbosacral segment and the pelvis, are the most common reasons of spine pain. The aim of this review is to present the current state of knowledge about lumbar spine pain in pregnant women with special focus on the pain connected with muscular, joint and ligament disorders. Pregnancy is a serious burden for the female osteo-skeletal system. Lumbar pain with different location and intensification is the negative consequence of the position changes during pregnancy. Pharmacotherapy could be useful only in cases of intensive low back pain, with possible application of small spectrum of drugs that are safe during pregnancy. Physical therapy including manual therapy exercises, massage and techniques of local anesthesia are alternative methods in case of low back pain in pregnant women.

    Pregnancies in renal transplant patients are considered to be high risk. Anemia is one of the major complications of pregnancy occurring among 65% to 85% of cases in this setting, especially since these patients carry additional risk factors. Herein we have presented five renal transplant recipients who were women who were treated with human recombinant erythropoietin due to severe anemia that developed during pregnancy. Hemoglobin levels below 9 g/dL after 3 weeks of oral iron administration were assumed to be qualifying criteria for erythropoietin treatment. No complication was observed to be associated with the treatment. Two of the five patients required blood transfusions despite erythropoietin administration. Two cases delivered small for gestational fetus age. Erythropoietin therapy in pregnant kidney transplant recipients should be considered to be a safe method to reduce the need for blood transfusions.

    Immunoreactive relaxin was measured in plasma samples obtained from human volunteers utilizing the RIA procedure of Sherwood et al., as modified by O'Byrne and Steinetz for heterologous plasma samples. Immunoreactive hormone was not detected in samples obtained from men, and only rarely in plasma of nonpregnant women. Immunoreactive relaxin was present as early as the fourth week of pregnancy and was detectable throughout the course of gestation. Immunoreactive relaxin tended to be higher early in pregnancy, and there was no peak just before parturition as occurs in many other species. Our results are at variance with those of Bryant and coworkers, who reported high levels of immunoreactive relaxin in men and nonpregnant as well as pregnant women. The possible reasons for this discrepancy are presented.

    Relaxin was measured in serum and amniotic fluid of 136 pregnant women between the 12th and 38th gestational week by means of a new human relaxin-RIA. The pregnancies consisted of 111 pathology-free single fetuses, 10 with rhesus incompatibility, 7 with chromosomal aberration and 8 with sonographic diagnosed abnormalities. Relaxin could be detected in all samples tested the levels being ten times lower in amniotic fluid compared to serum. Serum relaxin levels showed a slight but not statistically significant decrease with increasing gestational age, in amniotic fluid relaxin values were consistent over the course of pregnancy. The ratio of amniotic fluid to serum relaxin displayed a statistically significant increase from the 12th to 23rd week of pregnancy. Individual courses of relaxin concentration in amniotic fluid revealed only low intra-individual variations but distinct inter-individual differences.

    Aims Adiponectin is an adipokine that has anti-diabetic, anti-atherogenic, anti-inflammatory and angiogenic properties. This hormone has been implicated in both the physiological adaptation to normal pregnancy and obstetrical complications. The aims of this study were to determine normal maternal plasma concentrations of adiponectin throughout gestation and to explore the relationships between plasma adiponectin concentration, pregnancy, and maternal overweight. Study design A cross-sectional study was designed to include normal pregnant women (normal weight and overweight; 11–42 weeks of gestation), and non-pregnant women. Plasma adiponectin concentration was determined by immunoassay. Non-parametric statistics were used for analysis. Results (1) Adiponectin was detectable in the plasma of all patients; (2) there was no significant difference in the median adiponectin concentrations between pregnant and non-pregnant women; (3) plasma adiponectin concentrations were negatively correlated with gestational age only among normal weight pregnant women; and (4) overweight patients had significantly lower adiponectin concentrations than normal weight women. Conclusion Consistent with the increased insulin resistance and weight gain that occur in pregnancy, adiponectin concentrations were negatively correlated with gestational age. The results of this study and the nomogram herein presented can serve as the basis to explore the relationship between adiponectin and pregnancy complications and facilitate the clinical use of this important adipokine. Condensation Plasma adiponectin concentrations decrease with advancing gestational age only in nonobese women. PMID:17919116

    The trichothecene mycotoxin deoxynivalenol (DON) is a contaminant of crops worldwide and known to cause adverse health effects in exposed animals and humans. A small survey reported the presence of DON in maize samples in Bangladesh, but these data are insufficient to assess human exposure, and also, biomonitoring data are still scarce. The present study applied biomarker analysis to investigate the DON exposure of pregnant women in Bangladesh. Urine samples were collected from pregnant women living in a rural (n = 32) and in a suburban (n = 22) area of the country. Urines were subjected to enzymatic hydrolysis of glucuronic acid conjugates and to immunoaffinity column clean-up prior to LC-MS/MS analysis of DON and its de-epoxy metabolite DOM-1. The limits of detection (LOD) for DON and DOM-1 in urine were 0.16 ng/mL and 0.10 ng/mL, respectively. DOM-1 was not detected in any of the urines, whilst DON was detectable in 52% of the samples at levels ranging from 0.18-7.16 ng/mL and a mean DON concentration of 0.86 ± 1.57 ng/mL or 2.14 ± 4.74 ng/mg creatinine. A significant difference in mean urinary DON levels was found between the rural (0.47 ± 0.73 ng/mL) and suburban (1.44 ± 2.20 ng/mL) cohort, which may be related to different food habits in the two cohorts. Analysis of food consumption data for the participants did not show significant correlations between their intake of typical staple foods and DON levels in urine. The biomarker concentrations found and published urinary excretion rates for DON were used to estimate daily mycotoxin intake in the cohort: the mean DON intake was 0.05 µg/kg b.w., and the maximum intake was 0.46 µg/kg b.w., values lower than the tolerable daily intake of 1 µg/kg b.w. These first results indicate a low dietary exposure of pregnant women in Bangladesh to DON. Nonetheless, further biomonitoring studies in children and in adult cohorts from other parts of the country are of interest to gain more insight into DON exposure in the

    Zika virus is a cause of microcephaly and brain abnormalities (1), and it is the first known mosquito-borne infection to cause congenital anomalies in humans. The establishment of a comprehensive surveillance system to monitor pregnant women with Zika virus infection will provide data to further elucidate the full range of potential outcomes for fetuses and infants of mothers with asymptomatic and symptomatic Zika virus infection during pregnancy. In February 2016, Zika virus disease and congenital Zika virus infections became nationally notifiable conditions in the United States (2). Cases in pregnant women with laboratory evidence of Zika virus infection who have either 1) symptomatic infection or 2) asymptomatic infection with diagnosed complications of pregnancy can be reported as cases of Zika virus disease to ArboNET* (2), CDC's national arboviral diseases surveillance system. Under existing interim guidelines from the Council for State and Territorial Epidemiologists (CSTE), asymptomatic Zika virus infections in pregnant women who do not have known pregnancy complications are not reportable. ArboNET does not currently include pregnancy surveillance information (e.g., gestational age or pregnancy exposures) or pregnancy outcomes. To understand the full impact of infection on the fetus and neonate, other systems are needed for reporting and active monitoring of pregnant women with laboratory evidence of possible Zika virus infection during pregnancy. Thus, in collaboration with state, local, tribal, and territorial health departments, CDC established two surveillance systems to monitor pregnancies and congenital outcomes among women with laboratory evidence of Zika virus infection(†) in the United States and territories: 1) the U.S. Zika Pregnancy Registry (USZPR),(§) which monitors pregnant women residing in U.S. states and all U.S. territories except Puerto Rico, and 2) the Zika Active Pregnancy Surveillance System (ZAPSS), which monitors pregnant women

    The concerns of people on possible adverse health effects of radiofrequency radiation (RFR) generated from mobile phones as well as their supporting transmitters (base stations) have increased markedly. RFR effect on oversensitive people, such as pregnant women and their developing fetuses, and older people is another source of concern that should be considered. In this study, oxidative DNA damage and lipid peroxidation levels in the brain tissue of pregnant and non-pregnant New Zealand White rabbits and their newborns exposed to RFR were investigated. Thirteen-month-old rabbits were studied in four groups as non-pregnant-control, non-pregnant-RFR exposed, pregnant-control and pregnant-RFR exposed. They were exposed to RFR (1800 MHz GSM; 14 V/m as reference level) for 15 min/day during 7 days. Malondialdehyde (MDA) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels were analyzed. MDA and 8-OHdG levels of non-pregnant and pregnant-RFR exposed animals significantly increased with respect to controls (p < 0.001, Mann-Whitney test). No difference was found in the newborns (p > 0.05, Mann-Whitney). There exist very few experimental studies on the effects of RFR during pregnancy. It would be beneficial to increase the number of these studies in order to establish international standards for the protection of pregnant women from RFR.

    In late pregnancy, maternal insulin resistance occurs to support fetal growth but little is known about insulin-glucose dynamics close to delivery. This study measured insulin sensitivity in mice in late pregnancy, day (D) 16, and near term, D19, (term 20.5D). Non-pregnant (NP) and pregnant mice were assessed for metabolite and hormone concentrations, body composition by dual energy X-ray absorptiometry, tissue insulin signalling protein abundance by Western blotting, glucose tolerance and utilisation, and insulin sensitivity using acute insulin administration and hyperinsulinaemic-euglycaemic clamps with 3H-glucose infusion. Whole body insulin resistance occurred in D16 pregnant dams in association with basal hyperinsulinaemia, insulin-resistant endogenous glucose production and downregulation of several proteins in hepatic and skeletal muscle insulin signalling pathways relative to NP and D19 values. Insulin resistance was less pronounced at D19 with restoration of NP insulin concentrations, improved hepatic insulin sensitivity and increased abundance of hepatic insulin signalling proteins. At D16, insulin resistance at whole body, tissue and molecular levels will favour fetal glucose acquisition while improved D19 hepatic insulin sensitivity will conserve glucose for maternal use in anticipation of lactation. Tissue sensitivity to insulin, therefore, alters differentially with proximity to delivery in pregnant mice with implications for human and other species. PMID:26740602

    A visiting nurse agency created the Pregnant and Parenting Team Program, an innovative program for serving pregnant and parenting teen mothers to promote family and child health and family self-sufficiency. Public health nurses (PHNs) provide home visits that offer social, emotional, educational, and health care support to pregnant and parenting teen mothers 19 years of age and younger and their children. Foundational program pillars include: (1) a trusting relationship between teen mothers and a PHN through home visits; (2) outreach and coordination with schools, hospital, clinics, and human service agencies; (3) a comprehensive and intensive maternal mental health curriculum; and (4) community support and caring through provision of essential items needed for success in parenting. Measures of program effectiveness included identification of pregnant and parenting adolescent mothers, birth outcomes, active enrollment in school, delay of repeat pregnancy, maternal-infant bonding and attachment, use of community resources, and infant growth and development. Participants in the program were more likely to be enrolled in school and had better birth outcomes in comparison with nonparticipants. Outcome data collected from January 1, 2008 to July 23, 2010 demonstrated progress toward stated goals.

    Although an excess of human adult blood adherent cells inhibits the pokeweed mitogen- (PWM) induced normal adult lymphocyte proliferation and B cell maturation into immunoglobulin-containing cells (ICC), adherent cells collected from newborn infants or pregnant women at time of delivery were unable to exert a similar suppressor activity. After activation by Concanavalin A (Con A), newborns' and pregnant women's adherent cells acquired a suppressor activity comparable to that of control adult adherent cells. The adherent suppressor cell was shown to be radioresistant (3000 rad), indicating its probable monocytic orgin. Both monocyte-suppressor activities (MSA) observed in adulthood (spontaneously) and in the neonatal period (after activation) were dependent on prostaglandin E/sub 2/ (PGE/sub 2/) secretion, because they were abolished by indomethacin or a specific anti-PGE/sub 2/ anti-serum. Expression of MSA appeared to be under a negative regulation exerted by naturally occurring T suppressor lymphocytes present in the blood of newborns or pregnant women, because incubation of adult monocytes or Con A-activated newborn monocytes with newborns' or pregnant women's T lymphocytes resulted in a dramatic decrease of their MSA. These results strongly suggest that the lack of MSA in the neonatal period and in late pregnancy is a consequence of activation of T suppressor lymphocytes.

    We compared the levels of cell-free human placental lactogen (hPL) messenger RNA (mRNA) in maternal plasma at 28 to 32 weeks of gestation between women with diagnosis of placenta previa or invasive placenta and women with an uneventful pregnancy. Sensitivity and specificity of hPL mRNA for the prediction of invasive placenta were further explored. Plasma hPL mRNA were quantified by real-time reverse-transcriptase polymerase chain reaction in women with placenta previa (n = 13), invasive placenta (n = 5), and normal pregnancies (n = 92). Median (range) hPL mRNA was significantly higher in women with placenta previa, 782 (10-2301) copies/mL of plasma, and in those with invasive placenta, 615 (522-2102) copies/mL of plasma, when compared to normal pregnancies, 90 (4-4407) copies/mL of plasma, P < .01 and P < .05, respectively. We found a sensitivity of 100% and a specificity of 61.5% for the prediction of invasive placenta among women with placenta previa. In conclusion, expression of hPL mRNA is increased in plasma of women with placenta previa and invasive placenta at 28 to 32 weeks of gestation.

    About 20000 gastrointestinal endoscopies are performed annually in America in pregnant women. Gastrointestinal endoscopy during pregnancy raises the critical issue of fetal safety in addition to patient safety. Endoscopic medications may be potentially abortifacient or teratogenic. Generally, Food and Drug Administration category B or C drugs should be used for endoscopy. Esophagogastroduodenoscopy (EGD) seems to be relatively safe for both mother and fetus based on two retrospective studies of 83 and 60 pregnant patients. The diagnostic yield is about 95% when EGD is performed for gastrointestinal bleeding. EGD indications during pregnancy include acute gastrointestinal bleeding, dysphagia > 1 wk, or endoscopic therapy. Therapeutic EGD is experimental due to scant data, but should be strongly considered for urgent indications such as active bleeding. One study of 48 sigmoidoscopies performed during pregnancy showed relatively favorable fetal outcomes, rare bad fetal outcomes, and bad outcomes linked to very sick mothers. Sigmoidoscopy should be strongly considered for strong indications, including significant acute lower gastrointestinal bleeding, chronic diarrhea, distal colonic stricture, suspected inflammatory bowel disease flare, and potential colonic malignancy. Data on colonoscopy during pregnancy are limited. One study of 20 pregnant patients showed rare poor fetal outcomes. Colonoscopy is generally experimental during pregnancy, but can be considered for strong indications: known colonic mass/stricture, active lower gastrointestinal bleeding, or colonoscopic therapy. Endoscopic retrograde cholangiopancreatography (ERCP) entails fetal risks from fetal radiation exposure. ERCP risks to mother and fetus appear to be acceptable when performed for ERCP therapy, as demonstrated by analysis of nearly 350 cases during pregnancy. Justifiable indications include symptomatic or complicated choledocholithiasis, manifested by jaundice, cholangitis, gallstone

    Oxidized low density lipoproteins (oxLDL) formed in vivo induce a humoral immune response. Oxidative modification of LDL renders it immunogenic and a heterogeneous population of specific anti-oxLDL antibodies is produced. These antibodies could represent a biological marker of oxidative stress and serve as markers of atherosclerosis. Autoantibodies against oxLDL (oLAb) have been detected in human subjects practically of every age. oLAb also appear in the blood of pregnant women. Some studies have shown that the levels of antibodies to oxLDL were elevated in women with established preeclampsia. The present study was aimed to estimate the oLAb IgG levels in the first and second trimester of pregnancy. Furthermore, we estimated the correlation between maternal serum (MS) levels of oLAb and alpha-1-fetoprotein (MS AFP), human chorionic gonadotrophin (MS HCG) and trophoblast-specific-beta-1-glycoprotein (MS SP1), because these proteins are determined as a part of prenatal biochemical screening for fetal congenital abnormalities. Our study deals with the oLAb changes in women with pregnancy-induced hypertension. We also investigated the correlation between oLAb IgG and anticardiolipin antibodies IgG (ACA) in the serum of pregnant women. We examined 40 pregnant women attending Institute for Mother and Child Care for their antenatal care as outpatients. Routine blood samplings between the 9-13th week of pregnancy and 16-18th week of pregnancy were performed as a part of biochemical prenatal screening for fetal congenital abnormalities (Group 1). Their mean age was 27 +/- 4.1 years. Furthermore, we examined 26 women in the second or third trimester with pregnancy-induced hypertension (Group 2). Group 2 was compared with 49 pregnant women in the second or third trimester who were normotensive (Group 3). We used commercial standardized ELISA kits for determination of oLAb IgG, ACA IgG, MS AFP and MS HCG, MS SP1 was analyzed by single radial immunodiffusion. We did not find

    Between 1988 and 1991, we treated 595 women with breast cancer in the Breast Disease Section of the Cancer Research Foundation of Pakistan. We report here on 61 patients who were pregnant or lactating. Most patients presented at a late stage of disease because of ignorance, social taboos, or fear of hospitalization and operation. The largest diameter of the breast mass at presentation was 15 cm. Lymph nodes were involved in 70.5% of cases. Multiparity, young marriages, malnutrition, and unhygienic conditions are ripe in the rural environment of Pakistan. No oral contraceptives are used. Modern and conventional methods of treatment did not increase the survival rate of these cancer patients.

    Fluoxetine is used to treat a number of psychiatric conditions in humans and behavioral problems in animals. Its use in pregnancy must balance maternal benefit with potential risk to the fetus. Knowledge of adult and fetal drug disposition can assist clinicians in selecting therapy that minimizes adverse effects to the fetus. Nonhuman primate models are used frequently in drug dose-translation studies, and pregnancy in baboons has many similarities to human pregnancy. Accordingly, pharmacokinetic analysis of a series of fluoxetine and norfluoxetine administrations to pregnant baboons was performed. The mean maternal baboon steady-state clearance of fluoxetine (42 mL/min/kg) was considerably higher than that in humans. Norfluoxetine, the major active metabolite, had a higher metabolite-to-drug ratio (8.7) than that found in humans, particularly with oral dosing. These results are consistent with more extensive metabolism in baboons than in humans and leads to a higher clearance than would be expected from allometric scaling. Fetal-to-maternal fluoxetine and norfluoxetine ratios under steady-state conditions were similar to those in humans, with fetal concentrations of fluoxetine 42% and norfluoxetine 47% of maternal concentrations. The fetal clearance of fluoxetine (303 ± 176 mL/min) and norfluoxetine (450 mL/min) exceeded reported placental blood flow. Understanding these species-associated differences in metabolism is a prerequisite to extrapolating data between species. Nonetheless, nonhuman primates are likely to remain valuable models for pharmacokinetic studies during pregnancy, particularly those directed toward fetal neurodevelopmental effects. Our results also are applicable to determining appropriate dosing of nonhuman primates in clinical settings.

    From a feminist perspective, research on childbirth and women's health is a means to a positive change that is conducted in partnership with women for their benefit. A patient-led National Health System (NHS) (Hillan, 1999) also calls for consultation with patients and the wider public for shaping the current and future health services. This study was aimed at exploring and describing the expectations that pregnant women have regarding antenatal care service by the midwife practitioner. In-depth interviews were conducted in an antenatal unit of an Academic Hospital in Gauteng Povince. Data saturation was reached with a sample of eighteen pregnant women who were conveniently selected. Data analysis ran concurrently with data collection. A manual content analysis as described by Tesch was used. Lincoln and Guba's method of ensuring trustworthiness was adopted (Lincoln & Guba, 1985:328) Literature was undertaken to compare the findings of this study with those of other previous studies. Women displayed several common expectations that led to the saturation of data. It also became apparent from the findings that each woman had varied expectations. There were also some commonalities within the women's expectations. Health care, as the major expectation and a basic human right, appeared to be basically fulfilled, with the exception of interactional characteristics such as the communication of information, guidance, involvement, the understanding and explanation of aspects, freedom of choice, punctuality, individualized care and continuity of care. The conclusions that were reached let to recommendations for nursing practice, education, research and the formulation of guidelines for the midwife practitioner for the implementation of effective antenatal care, based on the identified expectations.

    Fetal glucocorticoids have an important role in the pre-partum maturation of physiological systems essential for neonatal survival such as glucogenesis. Consequently, in clinical practice, synthetic glucocorticoids, like dexamethasone, are given routinely to pregnant women threatened with pre-term delivery to improve the viability of their infants. However, little is known about the effects of maternal dexamethasone treatment on the glucogenic capacity of either the fetus or mother. This study investigated the effects of dexamethasone treatment using a clinically relevant dose and regime on glycogen deposition and the activities of glucose-6-phosphatase (G6Pase) and phosphoenolpyruvate carboxykinase (PEPCK) in the liver and kidney of pregnant ewes and their fetuses, and of non-pregnant ewes. Dexamethasone administration increased the glycogen content of both the fetal and adult liver within 36 h of beginning treatment. It also increased G6Pase activity in the liver and kidney of the fetuses but not of their mothers or the non-pregnant ewes. Neither hepatic nor renal PEPCK activity was affected by dexamethasone in any group of animals. These changes in glycogen content and G6Pase activity were accompanied by rises in the plasma glucose and insulin concentrations and by a fall in the plasma cortisol level in the fetus and both groups of adult animals. In addition, dexamethasone treatment raised fetal plasma tri-iodothyronine (T(3)) concentrations and reduced maternal levels of plasma T(3) and thyroxine, but had no effect on thyroid hormone concentrations in the non-pregnant ewes. These findings show that maternal dexamethasone treatment increases the glucogenic capacity of both the mother and fetus and has major implications for glucose availability both before and after birth.

    Iron homeostasis in pregnancy compensates for increased iron requirements and in women of child-bearing age for iron loss in menses. Oral administration of ferrous sulfate, prescribed to cure iron deficiency (ID) and ID anemia (IDA), often fails to increase hematological parameters and causes adverse effects. Recently, we demonstrated safety and efficacy of bovine lactoferrin (bLf) in pregnant women suffering from ID/IDA. Two clinical trials were conducted on pregnant and non-pregnant women of child-bearing age suffering from ID/IDA. In both trials, women received oral administration of bLf 100 mg/twice/day (Arm A), or ferrous sulfate 520 mg/day (Arm B). Hematological parameters, serum IL-6 and prohepcidin were assayed before and after therapy. Unlike ferrous sulfate, bLf increased hematological parameters (P less than 0.0001). In pregnant women, bLf decreased serum IL-6 (P less than 0.0001), and increased prohepcidin (P=0.0007). In non-pregnant women bLf did not change the low IL-6 levels while it increased prohepcidin (P less than 0.0001). Ferrous sulfate increased IL-6 (P less than 0.0001) and decreased prohepcidin (P=0.093). bLf established iron homeostasis by modulating serum IL-6 and prohepcidin synthesis, whereas ferrous sulfate increased IL-6 and failed to increase hematological parameters and prohepcidin. bLf is a more effective and safer alternative than ferrous sulfate for treating ID and IDA.

    We evaluated a two-rapid-test serial algorithm using the Determine and Genie II rapid assays, performed on-site in four peripheral laboratories during the French Agence Nationale de Recherches sur le SIDA (ANRS) 1201/1202 Ditrame Plus cohort developed for prevention of mother-to-child transmission of human immunodeficiency virus (HIV) infection in Côte d'Ivoire. A total of 1,039 specimens were retested by two commercial enzyme-linked immunosorbent assays (ELISAs). The following specimens were tested: 315 specimens found on-site to be infected with HIV type 1 (HIV-1), 8 specimens found on-site to be infected with HIV-2, 71 specimens found on-site to be infected with both HIV-1 and HIV-2, 40 specimens found on-site to have indeterminate results for HIV infection, and 605 specimens taken during a quality assurance program. For HIV discrimination, 99 positive serum samples (20 with HIV-1, 8 with HIV-2, and 71 with HIV-1 and HIV-2 on the basis of our rapid test algorithm) were retested by the Peptilav test, Western blot (WB) assays, and homemade monospecific ELISAs. Real-time DNA PCRs for the detection of HIV-1 and HIV-2 were performed with peripheral blood mononuclear cells from 35 women diagnosed on-site with HIV-1 and HIV-2 infections. Compared to the results of the ELISAs, the sensitivities of the Determine and Genie II assays were 100% (95% lower limit [95% LL], 99.1%) and 99.5% (95% confidence interval [95% CI], 98.2 to 99.9%), respectively. The specificities were 98.4% (95% CI, 96.9 to 99.3%) and 100% (95% LL, 99.3%), respectively. All serological assays gave concordant results for infections with single types. By contrast, for samples found to be infected with dual HIV types by the Genie II assay, dual reactivity was detected for only 37 samples (52.1%) by WB assays, 34 samples (47.9%) by the Peptilav assay, and 23 samples (32.4%) by the monospecific ELISAs. For specimens with dual reactivity by the Genie II assay, the rates of concordance between the real

    Maternal weight gain is the most important, manageable determinant of infant birth weight among adolescents. Negative attitudes toward weight gain may adversely affect maternal weight gain. We hypothesized that (a) negative attitudes toward pregnancy weight gain are more common among younger pregnant adolescents, and (b) negative attitudes toward pregnancy weight gain adversely affect adolescent maternal weight gain. The study subjects, 99, radially diverse, pregnant 13 through 18 year olds, completed the 18-item, Likert-format, Pregnancy and Weight Gain Attitude Scale. Responses to the questionnaire indicated that most (83.8%) of the adolescents we interviewed had a positive attitude toward pregnancy weight gain when they entered prenatal care. Univariate analyses revealed that attitudes toward weight gain were unrelated to the respondents' ages but inversely related to their prepregnant weights (-0.16; p = 0.06) and the severity of their symptoms of depression (r = -0.26; p = 0.004). Attitudes toward weight gain were also directly related to their family support (r = 0.17; p = 0.06). Weight gain was significantly related to 4 of the 18 scale items but not to the total attitude scale score. We conclude that (a) the developmental task of formulating a positive body image does not foster more negative attitudes toward pregnancy weight gain among younger adolescents; (b) negative weight gain attitudes are most common among heavier adolescents, depressed adolescents, and adolescents who do not perceive their families as supportive; and (c) negative weight gain attitudes could adversely affect pregnancy weight gain.

    Three women, aged 27, 32 and 30 years, respectively, suffered from headache, nausea and neurological abnormalities and were found to have an intracranial arteriovenous malformation (AVM). One of them after diagnosis had two pregnancies, both ended by caesarean section with good results. Another woman was 32 weeks pregnant when the AVM manifested itself with a haemorrhage; she recovered well and was delivered by caesarean section. After the AVM proved radiologically to have been obliterated, she delivered after her subsequent pregnancy by the vaginal route with vacuum extraction. The third woman was 15 weeks pregnant when major abnormalities developed. There was a large intracerebral haematoma with break-through to the ventricular system; this patient died. Intracranial haemorrhage during pregnancy is rate. It can result in maternal and foetal morbidity and mortality. It appears that pregnancy does not increase the rate of first cerebral haemorrhage from an AVM. The management of AVM rupture during pregnancy should be based primarily on neurosurgical rather than on obstetric considerations. Close collaboration with a team of neurologists, neurosurgeons, obstetricians and anaesthesiologists is mandatory.

    Pregnancy is a major life change for many women. The related biological changes, especially complications in its course and in the course of delivery, carry a risk of developing a variety of psychological problems and mental disorders. However, their treatment is challenging due to the teratogenic effects of most psychoactive drugs and specific requirements for entering different psychotherapeutic programs. Mental disorders during pregnancy are undoubtedly an important issue for both gynecology and psychiatry. There is still a discussion considering the question whether psychotherapy during pregnancy is safe, although no scientifically valid data contradicting the safety of psychotherapy during pregnancy has been published so far. Together with psychotherapy - as a treatment of choice - clinicians approve some other relatively safe treatment methods for psychiatric disorders in pregnant women. Light therapy, limited pharmacotherapy, ECT are included. The goal of this paper is to review current opinions of clinicians and researches concerning possibilities, indications and outcome of psychological treatments as a way to help pregnant women who suffer from different psychiatric conditions, and also because this subject is not yet present in Polish psychiatric journals.

    This review main purpose is to show nursing the present knowledge about cardiopulmonary resuscitation (CPR) in pregnant women because of the scarce information published by Spanish Nursing Publications. The bibliographical research was made using both the Medline (from January 1982 to March 1998) and Index de Enfermería databases. There, we can find 32 references from which only 23 were selected (all of them belong to the Medline database) in spite of 3 chapters that had already been selected from other different books. Although maternal cardiac arrest rarely happens during pregnancy, it is very important for sanitary staff to be familiarized with the specifics thecnics and equipment (ultrasound and cardiotocograph monitoring). This review describes the physiological changes that take place during pregnancy and have an incidence into CPR. The article also includes the conclusions about the checked papers and the peculiarities that have to be taken into account in each CPR, such as the fetal viability evaluation, right CPR position, airway and breathing, desfibrillation, external cardiac compression and use of pharmacologic therapy and intravenous fluids. Moreover, there is a special mention of the perimortem cesarean delivery features: antecedents, foetus-maternals consequences and managements, due to the fact that this surgical operation should be included inside the CPR protocols of the pregnant.

    Acute kidney injury (AKI) is costly and is associated with increased mortality and morbidity. An understanding of the renal physiologic changes that occur during pregnancy is essential for proper evaluation, diagnosis, and management of AKI. As in the general population, AKI can occur from prerenal, intrinsic, and post-renal causes. Major causes of pre-renal azotemia include hyperemesis gravidarum and uterine hemorrhage in the setting of placental abruption. Intrinsic etiologies include infections from acute pyelonephritis and septic abortion, bilateral cortical necrosis, and acute tubular necrosis. Particular attention should be paid to specific conditions that lead to AKI during the second and third trimesters, such as preeclampsia, HELLP syndrome, acute fatty liver of pregnancy, and TTP-HUS. For each of these disorders, delivery of the fetus is the recommended therapeutic option, with additional therapies indicated for each specific disease entity. An understanding of the various etiologies of AKI in the pregnant patient is key to the appropriate clinical management, prevention of adverse maternal outcomes, and safe delivery of the fetus. In pregnant women with pre-existing kidney disease, the degree of renal dysfunction is the major determining factor of pregnancy outcomes, which may further be complicated by a prior history of hypertension.

    Tuberculosis is a major cause of morbidity and mortality in women of childbearing age (15-44 years). Despite increased tuberculosis risk during pregnancy, optimal clinical treatment remains unclear: safety, tolerability, and pharmacokinetic data for many tuberculosis drugs are lacking, and trials of promising new tuberculosis drugs exclude pregnant women. To advance inclusion of pregnant and postpartum women in tuberculosis drug trials, the US National Institutes of Health convened an international expert panel. Discussions generated consensus statements (>75% agreement among panelists) identifying high-priority research areas during pregnancy, including: (1) preventing progression of latent tuberculosis infection, especially in women coinfected with human immunodeficiency virus; (2) evaluating new agents/regimens for treatment of multidrug-resistant tuberculosis; and (3) evaluating safety, tolerability and pharmacokinetics of tuberculosis drugs already in use during pregnancy and postpartum. Incorporating pregnant women into clinical trials would extend evidence-based tuberculosis prevention and treatment standards to this special population.

    Background: Human infection with avian influenza A H7N9 has emerged in China since February, 2013. The immunologic changes in pregnant women infected with H7N9 are not known. Objective: To report the clinical data and kinetic changes of immunity in a pregnant woman infected with H7N9 virus in Zhenjiang, Jiangsu, China. Methods: The clinical data were collected and immunity status was monitored in this patient. Results: H7N9 virus became undetectable in sputum from 14 days since onset of symptoms after effective antiviral therapy with oseltamivir and symptomatic/supporting treatments. The symptoms and signs in this patient gradually improved from 15 days since onset of symptoms. Peripheral lymphocytes initially decreased and gradually increased. The percentage of CD4+ T cells increased since 16 days after onset of symptoms. The kinetic changes of cytokines including IFN-γ, IFN-α, TNF-α, IL-10 and TGF-β1 matched the development and recovery of illness. Her family members, including her parents exposed to H7N9 positive materials in poultry market, were H7N9 negative. Conclusions: Our results indicate that pregnant women are susceptible to H7N9 virus and H7N9 infection in pregnant women is curable without significant impact on fetus. Kinetic changes of pro-inflammatory and anti-inflammatory cytokines play a role in the pathogenesis and clinical outcome in the pregnant patient with H7N9 infection. PMID:25126178

    The enzyme FASN (fatty acid synthase) is potentially related with hypertension and metabolic dysfunction. FASN is highly expressed in the human placenta. We aimed to investigate the relationship circulating FASN has with blood pressure, maternal metabolism and newborn parameters in healthy pregnant women. Circulating FASN was assessed in 115 asymptomatic pregnant women in the second trimester of gestation along with C-peptide, fasting glucose and insulin, post-load glucose lipids, HMW-adiponectin and blood pressure (the latter was assessed in each trimester of gestation). At birth, newborns and placentas were weighed. FASN expression was also able to be assessed in 80 placentas. Higher circulating FASN was associated with lower systolic blood pressure (SBP), with a more favourable metabolic phenotype (lower fasting glucose and insulin, post load glucose, HbAc1, HOMA-IR and C-peptide), and with lower placental and birth weight (all p < 0.05 to p < 0.001). Placental FASN expression related positively to circulating FASN (p < 0.005) and negatively to placental weight (p < 0.05). Our observations suggest a physiological role of placental FASN in human pregnancy. Future studies will clarify whether circulating FASN of placental origin does actually regulate placental and fetal growth, and (thereby) has a favourable influence on the pregnant mother’s insulin sensitivity and blood pressure.

    Potential sanitary effects related to electromagnetic fields exposure raise public concerns, especially for fetuses during pregnancy. Human fetus exposure can only be assessed through simulated dosimetry studies, performed on anthropomorphic models of pregnant women. In this paper, we propose a new methodology to generate a set of detailed utero-fetal unit (UFU) 3D models during the first and third trimesters of pregnancy, based on segmented 3D ultrasound and MRI data. UFU models are built using recent geometry processing methods derived from mesh-based computer graphics techniques and embedded in a synthetic woman body. Nine pregnant woman models have been generated using this approach and validated by obstetricians, for anatomical accuracy and representativeness.

    Prevalence of antibodies against Toxoplasma gondii was studied in 534 pregnant women and 40 domestic cats in Grenada, West Indies. Antibodies (IgG) for T. gondii were sought in human sera by an enzyme-linked immunosorbent assay and in cat sera by using the modified agglutination test (MAT). Antibodies were found in 57 % of pregnant women. Seroprevalence increased with age; 51% of 15- to 19-yr-old women (100 total) had antibodies versus 60% of 20- to 24-yr-old women (127 total). Antibodies to T. gondii (MAT, 1:25 serum dilution) were found in 35% of cats; titers were 1:25 in 7 cats, 1:50 in 4 cats, and 1:500 in 3 cats. Epidemiological data suggested that the ingestion of food or water contaminated with oocysts was an important mode of transmission of T. gondii to women.

    The biotin-avidin immunoperoxidase staining method and antisera against highly purified porcine relaxin were used to localize relaxin in the genital tract of pregnant and nonpregnant women. Formalin-fixed tissue specimens from normal placenta, decidua, myometrium, vagina, corpus luteum, and Fallopian tubes were studied. In pregnant women, relaxin was found in the placental syncytiotrophoblast, decidua, and corpus luteum. In nonpregnant women, relaxin was identified in the corpus luteum and endometrium in the secretory, but not in the proliferative, phase. Myometrium, cervix, vagina, and Fallopian tubes were negative for relaxin. This is the first report describing relaxin in the nonpregnant corpus luteum, and we also confirm results of an early disputed study claiming that endometrium in the secretory phase contains relaxin. The origin and biological role of human endometrial relaxin remain to be studied.

  6. What are pregnant women's information needs and information seeking behaviors prior to their prenatal genetic counseling?

    As a result of the Human Genome Project, more genetic diagnostic tests have become available to the public and genetic-related information has also grown exponentially. Pregnant women are now routinely offered tests for chromosomal disorders and screenings for genetic conditions that are relevant to their situations. In order to facilitate the information system (IS) development to support their informed decision-making, it is imperative for the IS designer to recognize their unique information needs and patterns of information seeking behavior (ISB) first. This paper presents results of a pilot study that examined pregnant women's information needs, ISBs, and information resources used prior to their prenatal genetic counseling. Findings suggest three distinctive areas, content, format, and timing, for IS design considerations.

    This paper presents the computational electromagnetic dosimetry inside an anatomically based pregnant woman models exposed to electromagnetic wave during magnetic resonance imaging. The two types of pregnant woman models corresponding to early gestation and 26 weeks gestation were used for this study. The specific absorption rate (SAR) in and around a fetus were calculated by radiated electromagnetic wave from highpass and lowpass birdcage coil. Numerical calculation results showed that high SAR region is observed at the body in the vicinity of gaps of the coil, and is related to concentrated electric field in the gaps of human body such as armpit and thigh. Moreover, it has confirmed that the SAR in the fetus is less than International Electrotechnical Commission limit of 10W/kg, when whole-body average SARs are 2W/kg and 4W/kg, which are the normal operating mode and first level controlled operating mode, respectively.

    2007-05-01

    At times, obstetricians are called upon to assist pregnant women in making clinical choices between options that may selectively disadvantage either the mother or the fetus. If a mother chooses a therapeutic course that disadvantages the fetus the physician may feel distressed. In this paper we argue that the choices made by mothers are almost always in the interests of the fetus, and supported by physicians. When there is disagreement it is often due to poor communication. While acknowledging that the rare circumstances in which the physician and patient wish to pursue different clinical paths can be stressful for the provider, we explain why obstetricians should accept the judgment of their patient in all instances. Finally, we will maintain that positing a choice between maternal and fetal interests is, in fact, creating a false choice, in as much as options are presented as being exclusive, when in fact that is not the case.

    Heroin misuse in pregnancy is a significant health and social problem, and it can have an adverse effect on the mother and the baby. Although heroin and methadone have no specific teratogenic potential, 48–94% of children exposed in utero will have neonatal abstinence syndrome (NAS). The primary aim of this case report is to raise awareness of NAS among clinicians and to remind them that although very common, it is not inevitable. The risk of NAS can be further minimised by offering comprehensive and co-ordinated antenatal care that addresses the various biopsychosocial needs of the pregnant woman. Further, a brief description of NAS and a review of evidence in the field of management of opioid misuse in pregnancy, as relevant to this case, are provided. We have also included the patient’s own reflections on her pregnancy and treatment. PMID:22328902

    AIM: To correlate gastric contractility, gastrointestinal transit, and hormone levels in non-pregnant (estrous cycle) and pregnant rats using noninvasive techniques. METHODS: Female rats (n = 23) were randomly divided into (1) non-pregnant, (contractility, n = 6; transit, n = 6); and (2) pregnant (contractility, n = 5; transit, n = 6). In each estrous cycle phase or at 0, 7, 14, and 20 d after the confirmation of pregnancy, gastrointestinal transit was recorded by AC biosusceptometry (ACB), and gastric contractility was recorded by ACB and electromyography. After each recording, blood samples were obtained for progesterone and estradiol determination. RESULTS: In the estrous cycle, despite fluctuations of sex hormone levels, no significant changes in gastrointestinal motility were observed. Days 7 and 14 of pregnancy were characterized by significant changes in the frequency of contractions (3.90 ± 0.42 cpm and 3.60 ± 0.36 cpm vs 4.33 ± 0.25 cpm) and gastric emptying (168 ± 17 min and 165 ± 15 min vs 113 ± 15 min) compared with day 0. On these same days, progesterone levels significantly increased compared with control (54.23 ± 15.14 ng/mL and 129.96 ± 30.52 ng/mL vs 13.25 ± 6.31 ng/mL). On day 14, we observed the highest level of progesterone and the lowest level of estradiol compared with day 0 (44.3 ± 15.18 pg/mL vs 24.96 ± 5.96 pg/mL). CONCLUSION: Gastrointestinal motility was unaffected by the estrous cycle. In our data, high progesterone and low estradiol levels can be associated with decreased contraction frequency and slow gastric emptying. PMID:27433089

    Sexually transmitted infections (STIs) are major public health challenge especially in developing countries. This study was designed to determine the prevalence of Hepatitis B virus (HBV), Hepatitis C Virus (HCV), Human immunodeficiency virus (HIV), and Human T-cell lymphotropic Virus type I (HTLV-I) among pregnant women attending antenatal clinic, in Ladoke Akintola University Teaching Hospital, Osogbo, and South-Western Nigeria. One hundred and eighty two randomly selected pregnant women were screened for HBsAg, anti-HCV, anti-HIV and HTLV-1 IgM antibodies using commercially available ELISA kit. Of the 182 blood samples of pregnant women screened whose age ranged from 15-49 years, 13 (7.1%), 5 (2.7%), 9 (4.9%), and 44 (24.2%) were positive for HBsAg, anti-HCV, anti-HIV, and HTLV-1 IgM antibodies, respectively. The co-infection rate of 0.5% was obtained for HBV/HCV, HBV/HIV, HIV/HTLV-1, and HCV/HTLV-1 while 1.1% and 0% was recorded for HBV/HTLV-1 and HCV/HIV co-infections, respectively. Expected risk factors such as history of surgery, circumcision, tattooing and incision showed no significant association with any of the viral STIs (P > 0.05). This study shows that there is the need for a comprehensive screening of all pregnant women for HBsAg, anti-HCV, anti-HIV and HTLV-1 to prevent mother to child transmission of these viral infections and its attending consequences.

    Listeriosis, a severe disease that results from exposure to the foodborne pathogen Listeria monocytogenes, is responsible for approximately 2500 illnesses and 500 deaths in the United States each year. Pregnant women are 20 times more likely to develop listeriosis than the general population, with adverse pregnancy outcomes that include spontaneous abortions, stillbirths, and neonatal meningitis. The objective of this study was to determine an infective dose that resulted in stillbirths and infectivity of selected tissues in pregnant guinea pigs. Pregnant guinea pigs were exposed orally on gestation day 35 to 10(4) to 10(8) L. monocytogenes CFU in sterile whipping cream. L. monocytogenes was recovered at 64, 73, 90, and 100% from the livers of animals infected with 10(5), 10(6), 10(7), and 10(8) CFU, respectively. In dams exposed to > or =10(6) CFU, L. monocytogenes was cultured from 50% of the spleen samples and 33% of the gallbladder samples. Eleven of 34 dams infected with > or =10(6) CFU delivered stillborn pups. L. monocytogenes was cultured from the placenta, liver, and brain tissue of all stillbirths. Dams that delivered nonviable fetuses after treatment with > or =10(7) L. monocytogenes CFU had fecal samples positive for L. monocytogenes at every collection posttreatment. On the basis of a log-logistic model, the dose that adversely affected 50% of the pregnancies was approximately 10(7) L. monocytogenes CFU compared with that estimated from a human outbreak of 106 CFU. Listeriosis in pregnant guinea pigs can result in stillbirths, and the overall disease is similar to that described in nonhuman primates and in humans.

    Sixteen Wistar rats were studied in the last week of pregnancy. Another group of 6 nonpregnant animals served as control. Eight pregnant and 6 control ratas were kept in the cold room at 4 degrees C for 4 days, while 8 pregnant rats remained at 22 degrees C. After blocking the thyroid gland with potassium perchlorate to prevent iodine reutilization, a dose of 4 microCi of 125I-T3 was injected i.p. Thereafter, animals were placed in individual metabolic cages for separate 24 h collection of urine and feces. Heparinized blood samples were obtained at 4, 14, 24 and 28 h following tracer injection. Pregnant rats exposed to cold had a significant increase in T3 fractional turnover as compared to pregnants at 22 degrees C (p < 0.005) and to controls at 4 degrees C (p < 0.02). No changes were observed in space of distribution, serum concentration and body pool of T3. Degradation of this hormone, however, was significantly augmented (p < 0.05) in pregnants at 4 degrees C as compared to pregnants at 22 degrees C, although not when compared to controls at 4 degrees C. The urinary excretion of 125I was increased in pregnants in the cold (p <0.005) versus pregnants at 22 degrees C. The metabolic (p < 0.005), urinary (p < 0.001) and fecal (p < 0.05) clearances in pregnants at 4 degrees C were augmented with respect to the other two groups.(ABSTRACT TRUNCATED AT 250 WORDS)

    To evaluate attitudes and policies toward pregnant radiology residents, a questionnaire was sent to the chiefs of radiology residency programs across the country. A return rate of 76.4% and a response rate of 75.4% were achieved. A large majority of the respondents indicated that schedule changes would be made to avoid excessive exposure of a pregnant resident to radiation. The accommodations they suggest are reviewed, and suggestions are made that would help alleviate some of the stress and conflicts that invariably arise when a resident becomes pregnant.

    The fetal stress responses in sows euthanized by electrical current during their second and last trimester of pregnancy (G1 and G2) were evaluated. Three methods of euthanasia of pregnant sows generally applicable to cases of epizootic or emergency slaughter were investigated: 1. conventional application of electrical current to the head and heart (HH); 2. application of electrical current to the head, heart and the uterus (HHU); 3. application of electrical current to the head, heart and from the upper body to the vagina (HHV). Fetuses were delivered by cesarean section at intervals of 3 to 4 minutes and remained attached to the sow by the umbilical cord. Fetal vitality, reflexes, heart rate, blood pressure, rectal body temperature, intracardial arteriovenous pCO2, pH and lactic acid were monitored for a period of 30 minutes. No method was found to kill the fetal pigs immediately. In fetuses at G1 there were no significant differences between the HH and HHU and HHV methods. Fetuses at G2 showed a significantly faster decrease in heart rate and blood pressure as well as a shorter period of time for the absence of fetal body movements and reflexes for the HHT method, compared to the other methods. Since it is not yet known to what extent the fetal pig experiences pain and suffering, the prolonged process of dying for the in utero fetus due to hypoxia which includes struggling and gasps is inconsistent with criteria for humane euthanasia and animal welfare.

    Hepatitis C virus (HCV) affects about 3% of the world’s population, with the highest prevalence in individuals under 40. The prevalence in pregnant women varies with geographical distribution (highest in developing countries). Prevalence also increases in sub-populations of women at high risk for blood-transmitted infections. HCV infection in pregnancy represents a non-negligible problem. However, most of the past antiviral regimens cannot be routinely offered to pregnant or breastfeeding women because of their side effects. We briefly reviewed the issue of treatment of HCV infection in pregnant/breastfeeding women focusing on the effects of the new direct-acting antivirals on fertility, pregnancy and lactation in animal studies and on the potential risk for humans based on the pharmacokinetic properties of each drug. Currently, all new therapy regimens are contraindicated in this setting because of lack of sufficient safety information and adequate measures of contraception are still routinely recommended for female patients of childbearing potential.

    Inhibition of fetal movement is one mechanism behind the development of multiple congenital contracture-type defects in developing fetuses of humans and animals. We tested the alkaloids anabasine, lobeline, and myosmine for agonist actions, and sensitivity to alpha conotoxins EI and GI blockade at fetal muscle-type nicotinic acetylcholine receptors (nAChR) expressed by TE-671 cells. We also determined if the alkaloids decreased fetal movement in an IV dosed, day 40 pregnant goat model. In TE-671 cells, all three alkaloids elicited concentration-dependent changes in membrane potential sensing dye fluorescence. 1.0 μM alpha conotoxin GI shifted the concentration-effect curves of anabasine and myosmine to the right, and decreased maximal responses. Neither of the conotoxins blocked the actions of lobeline in TE-671 cells. In the day 40 pregnant goats, 0.8 mg/kg anabasine abolished fetal movement at 30 and 60 min after dosing and fetal movement was reduced by lobeline and myosmine. The blockade of anabasine and myosmine actions in TE-671 cells by alpha conotoxin GI indicates that they are agonists at fetal muscle-type nAChR. All three alkaloids did significantly decrease fetal movement in the day 40 pregnant goat model suggesting a potential for these alkaloids to cause multiple congenital contracture-type defects in developing fetuses.

Six putative periodontopathic bacteria (Porphyromonas gingivalis [Pg], Aggregatibacer actinomycetemcomitans [Aa], Fusobacterium nucleatum [Fn], Prevotella intermedia [Pi], Tannerella forsythia [Tf], and Treponema denticola [Td]) and three herpesviruses (Epstein-Barr virus [EBV], human cytomegalovirus [HCMV], and herpes simplex virus [HSV]) were detected. Socio-demographic data and oral health related behaviors, and salivary estradiol and progesterone levels were also collected. The results showed no significant differences in socio-demographic background, oral health related behaviors, and salivary estradiol and progesterone levels between the two groups (all P > 0.05). The detection rates of included periodontopathic microorganisms were not significantly different between the two groups (all P > 0.05), but the coinfection rate of EBV and Pg was significantly higher in the case group than in the control group (P = 0.028). EBV and Pg coinfection may promote the development of chronic periodontitis among pregnant women. PMID:27301874

    Body skin temperature is a useful parameter for diagnosing diseases and infrared thermography can be a powerful tool in providing important information to detect body temperature changes in a noninvasive way. The aim of this work was to study the pattern of skin temperature during pregnancy, to establish skin temperature reference values and to find correlations between these and the pregnant population characteristics. Sixty-one healthy pregnant women (mean age 30.6 ± 5.1 years) in the 8th-40th gestational week with normal pregnancies were examined in 31 regions of interest (ROI). The ROIs were defined all over the body in order to determine the most influenced by factors such as age or body mass index (BMI). The results obtained in this work highlight that in normal pregnant women the skin temperature is symmetrically distributed, with the symmetrical areas differing less than 0.5 °C , with a mean value of 0.25 ± 0.23 °C . This study identified a significant negative correlation between the BMI and temperature. Age has been shown to have great influence on the skin temperature, with a significant increase of temperature observed with age. This work explores a novel medical application of infrared thermography and provides a characterization of thermal skin profile in human pregnancy for a large set of ROIs while also evaluating the effects of age and BMI.

    Pregnancy malaria (PM) is associated with poor pregnancy outcomes, and can arise due to relapse, recrudescence or a re-infection with heterologous parasites. We have used the Plasmodium chabaudi model of pregnancy malaria in C57BL/6 mice to examine recrudescence and heterologous infection using CB and AS parasite strains. After an initial course of patent parasitemia and first recrudescence, CB but not AS parasites were observed to recrudesce again in most animals that became pregnant. Pregnancy exacerbated heterologous CB infection of AS-experienced mice, leading to mortality and impaired post-natal growth of pups. Parasites were detected in placental blood without evidence of sequestration, unlike P. falciparum but similar to other malaria species that infect pregnant women. Inflammatory cytokine levels were elevated in pregnant females during malaria, and associated with intensity of infection and with poor outcomes. Pups born to dams during heterologous infection were more resistant to malaria infections at 6–7 weeks of age, compared to pups born to malaria-experienced but uninfected dams or to malaria-naïve dams. In summary, our mouse model reproduces several features of human PM, including recrudescences, heterologous infections, poor pregnancy outcomes associated with inflammatory cytokines, and modulation of offspring susceptibility to malaria. This model should be further studied to explore mechanisms underlying PM pathogenesis. PMID:27467392

  2. Characterization and differential expression of microRNAs in the ovaries of pregnant and non-pregnant goats (Capra hircus)

    PubMed Central

    2013-01-01

    Background Ovarian follicular development and hormone secretion are complex and coordinated biological processes which will usually be altered during pregnancy. Ovarian function is tightly regulated by a multitude of genes, and also by some specific miRNAs. It is necessary to identify the differentially expressed miRNAs in the ovaries of pregnant and non-pregnant mammals, in order to further understand the role of miRNA-mediated post-transcriptional regulation in mammalian reproduction. Here, we performed a comprehensive search for hircine miRNAs using two small RNA sequencing libraries prepared from the ovaries of pregnant and non-pregnant goats. Results 617 conserved and 7 putative novel miRNAs were identified in the hircine ovaries. A total of 471 conserved miRNAs (76.34%) were co-expressed in both pregnant and non-pregnant libraries, and 90 pregnancy-specific and 56 non-pregnancy-specific conserved miRNAs were identified. Additionally, 407 unique miRNAs (65.96%) were significantly differentially expressed in the pregnant and non-pregnant libraries, of which 294 were upregulated and 113 were downregulated in the pregnant library compared to the non-pregnant library. Further analysis showed that miR-143 was predicted to bind to the target sequences of Frizzled-6 and -3 receptor genes in the Wnt/beta-catenin signaling pathway, and let-7b may target the Activin receptor I and Smad 2/3 genes in the TGF-beta signaling pathway. The expression level of 5 randomly selected miRNAs were analyzed by quantitative real-time PCR (q-PCR), and the results demonstrated that the expression patterns were consistent with the Solexa sequencing results. Conclusions The identification and characterization of differentially expressed miRNAs in the ovaries of pregnant and non-pregnant goats provides important information on the role of miRNA in the regulation of the ovarian development and function. This data will be helpful to facilitate studies on the regulation of miRNAs during

  3. Reducing morbidity and mortality among pregnant obese.

    Harper, Ann

    2015-04-01

    Obesity is increasing; in the UK, almost 20% of pregnant women have a body mass index (BMI) of ≥30 kg/m(2). Obese mothers have increased risks of pregnancy complications including miscarriage, congenital anomaly, gestational diabetes, pre-eclampsia, macrosomia, induction of labour, caesarean section, anaesthetic and surgical complications, post-partum haemorrhage, infection and venous thromboembolism. Complications tend to be greater in those with the highest BMIs. In recent triennia, obesity (27-29%) was over-represented in maternal mortality figures. Strategies to reduce morbidity and mortality include calculating BMI at booking visit to identify obese mothers and plan their antenatal care and delivery. This should include nutritional and lifestyle advice, screening for gestational diabetes and pre-eclampsia, thromboembolism risk assessment, antenatal anaesthetic review if BMI is ≥ 40 kg/m(2), ensuring availability of robust theatre tables and other equipment and involving senior doctors, especially in the labour ward. Afterwards, continuing weight reduction should be encouraged to reduce future pregnancy and health risks.

    2011-05-01

    This descriptive-exploratory study using a qualitative approach was undertaken to describe the perceptions of pregnant adolescents in relation to social support provided during pregnancy. Twelve adolescents in their first pregnancy who frequented the outpatient health service in Passo Fundo in the state of Rio Grande do Sul (Brazil) participated in the study. The data was obtained by semi-structured interviews, genograms and ecomaps and was assessed by thematic analysis. It highlighted the need for support to overcome the fears and challenges of motherhood. The mothers and partners were perceived as the main sources of support in affective and material terms. Common sense knowledge prevailed in the information dimension and pregnancy as a mediator in the reconciliation with the father fulfilled the emotional dimension. The perception of the dimension of positive social interaction was blurred by self-imposed isolation. Thus the adolescent's perception of the social support received is clear in relation to the family nucleus and includes the people in the family circle. The network of care outside the family, including the healthcare services, is tenuous and generated the perception of psychosocial difficulties. This reveals the need for greater investment of primary healthcare professionals in the inclusion of first-time-pregnancy adolescents in social care groups, which ensure the healthy progress of the pregnancy.

    The management of acne vulgaris in the setting of pregnancy raises important clinical considerations regarding the efficacy and safety of acne treatments in this special patient population. Particular challenges include the absence of safety data, discrepancy in safety data between different safety rating systems, and lack of evidence-based recommendations for the treatment of acne during pregnancy. Nonetheless, many therapeutic options exist, and the treatment of acne in pregnant women can be safely and often effectively accomplished. For mild or moderate disease, patients can be treated with topical antimicrobial agents, anti-inflammatory agents, as well as glycolic and salicylic acid. Several topical agents, notably benzoyl peroxide, previously viewed as potentially dangerous are cited by many sources as being considered safe. When necessary, systemic therapies that can be safely added include penicillins, amoxicillin, cephalosporins, erythromycin, clindamycin, and tetracyclines or sulfonamides, depending on the stage of fetal development. Adjunct therapy may include phototherapy or laser treatments. Physicians should work with this often highly motivated, safety-conscious patient population to tailor an individualized treatment regimen. This treatment regimen will likely shift throughout the different stages of fetal development, as distinct safety considerations are raised prior to conception as well as during each of the trimesters of pregnancy. Important considerations regarding acne management in breast-feeding mothers is also discussed.

    MeHg is a well-documented neurotoxicant even at low levels of exposure. Developing brain, in particular, is vulnerable to that. Through bioaccumulating to differing degrees in various fish species, it can have serious adverse effects on the development and functioning of the human central nervous system, especially during prenatal exposure. Therefore, the purpose of this study was to investigate mercury concentration in hair samples of pregnant women living in Mahshahr located in Khuzestan province, Iran. It assessed the association between fish consumption and specific characteristics that can influence exposure. From April to June 2008, 149 pregnant women were invited to participate in this study. An interview administered questionnaire was used to collect information about age, body weight, height, fish (fresh, canned and shrimp) consumption, pregnancy stage, residence duration, education level, family income and number of dental amalgam fillings. The obtained results showed that the geometric mean and range for hair total Hg concentration was 3.52 microg/g (0.44-53.56 microg/g). About 5.4% of mothers had hair total Hg levels in excess of 10 microg/g. Maternal hair mercury level was less than threshold level of WHO (5 microg/g). As expected, there was a clear increase in hair Hg with reported fresh marine fish consumption (p=0.04). The highest mean for hair mercury level in a group who consumed fish several times per week, was 4.93 microg/g. Moreover, a significant effect of age and residential time on Hg concentration in the hair of the women was found. Pregnant women in Mahshahr consumed large amounts of fish; consequently, most of their offspring were prenatally exposed to moderately high levels of mercury. The results found suggest that pregnant women should decrease their fish consumption.

    A biokinetic model for strontium (Sr) for the pregnant woman and fetus (Sr-PWF model) has been developed for use in the quantification of doses from internal radiation exposures following maternal ingestion of Sr radioisotopes before or during pregnancy. The model relates in particular to the population of the Techa River villages exposed to significant amounts of ingested Sr radioisotopes as a result of releases of liquid radioactive wastes from the Mayak plutonium production facility (Russia) in the early 1950s. The biokinetic model for Sr metabolism in the pregnant woman was based on a biokinetic model for the adult female modified to account for changes in mineral metabolism during pregnancy. The model for non-pregnant females of all ages was developed earlier with the use of extensive data on (90)Sr-body measurements in the Techa Riverside residents. To determine changes in model parameter values to take account of changing mineral metabolism during pregnancy, data from longitudinal studies of calcium homeostasis during human pregnancy were analysed and applied. Exchanges between maternal and fetal circulations and retention in fetal skeleton and soft tissues were modelled as adaptations of previously published models, taking account of data on Sr and calcium (Ca) metabolism obtained in Russia (Southern Urals and Moscow) relating to dietary calcium intakes, calcium contents in maternal and fetal skeletons and strontium transfer to the fetus. The model was validated using independent data on (90)Sr in the fetal skeleton from global fallout as well as unique data on (90)Sr-body burden in mothers and their still-born children for Techa River residents. While the Sr-PWF model has been developed specifically for ingestion of Sr isotopes by Techa River residents, it is also more widely applicable to maternal ingestion of Sr radioisotopes at different times before and during pregnancy and different ages of pregnant women in a general population.

    Choline is an essential nutrient for humans and its availability during pregnancy is important for optimal fetal development. The Food and Nutrition Board of the Institute of Medicine in the United States of America has set the adequate choline intake during pregnancy at 450 mg/day. There is limited data available on normal plasma choline concentrations in pregnancy. Moreover, there are neither documented studies of choline intake among pregnant women in the Jamaican population nor of free plasma choline concentrations during pregnancy. Sixteen women presenting to the antenatal clinic of the University Hospital of the West Indies (UHWI) at 10−15 weeks of gestation were selected for this pilot study. A food frequency questionnaire was administered to estimate frequency of consumption of foods rich in choline. Fasting blood samples were collected by venepuncture and plasma assayed for choline using liquid chromatography electrospray ionization isotopic dilution mass spectrometry. Most of the women reported consumption of diets that delivered less than the recommended choline intake (mean ± SEM, 278.5 ± 28.9 mg). Mean plasma choline concentration was 8.4 ± 0.4 μmol/L. This falls below the normal concentration (10 μmol/L) reported for individuals that are not pregnant and pregnant (14.5 μmol/L). The results of this study may be an indication that the choline included in the diet of pregnant women in Jamaica may not be adequate to meet both the needs of the mother and fetus and that further studies are warranted to determine clinical implications.

    Peripartum cardiomyopathy is a rare but important cause of maternal morbidity and mortality. Women with peripartum cardiomyopathy often present with symptoms and signs of heart failure. The diagnosis of peripartum cardiomyopathy is made after all other causes of heart failure are excluded. Emphasis is on the immediate recognition of an unwell pregnant or recently pregnant woman, early diagnosis with the use of echocardiography, and the correct treatment of heart failure.

    Hemorrhages from arteriovenous malformations (AVMs) in pregnant females are rare, but they are known to lead to high maternal and infant mortality. There are no standards for AVM treatment in pregnant females. Many authors believe that AVM resection before delivery improves the prognosis for life and health of the mother and fetus. In this paper, we present a case of successful surgical treatment of a female patient with AVM hemorrhage at 20 weeks and address management issues of these patients.

    The introduction describes the series of manuscripts resulting from the Hungarian Project for monitoring suicide attempts in pregnant women, as well as a history of the project, its various phases and participating individuals. This unique database contains information on all patients who attempted suicide by "self-poisoning" and were cared for at central toxicological inpatient clinic in Budapest, between 1960 and 1993. A total of 1044 patients were pregnant women, of which 19 died and 411 delivered live-born babies. Of these 411 live-born children, 367 exposed children were examined and/or evaluated. This is the first report of data on the human teratogenic potential of 93 medicinal products separately used for a suicide attempt during pregnancy. Each manuscript presents results for drugs used by at least 10 pregnant women for a suicide attempt, whereas the final paper summarizes the data of drugs used rarely for suicide attempt by pregnant women. Each patient consented to participate in the study. Critical information collected under medical supervision included examination of the patients upon admittance, stage of pregnancy at suicide attempt, blood levels of the drug(s) taken for the suicide attempt (at admittance), evaluation of the infant at birth for gestational age, weight and congenital abnormalities, and follow-up studies for 2 years after a child's birth. These studies provide insight into the potential effects of a high dose of a drug or drugs taken during pregnancy because it is well accepted that "pulse high doses" of a drug during the initial susceptible period of pregnancy are those most likely to result in congenital abnormality. Although it is obvious that these data are not sufficient to ensure safety, and that it is necessary to have a larger population of exposed children, to achieve better statistical power, as well as to include data on other populations, this collection of papers provides an important introduction of the so-called disaster

    Clinical research in the pregnant population allows for delivery of quality, evidence-based care in obstetrics. However, in recent years, the field of obstetrics has faced severe challenges in the recruitment of the pregnant population into clinical trials, a struggle also shared by several other medical disciplines. We candidly describe our failure to recruit a healthy population of overweight and obese pregnant women in their first trimester. We were then able to glean unsuccessful and successful recruitment approaches and improve our recruitment effort by autopsy of failed strategies and with guidance from a survey disseminated to improve our understanding of community feelings about participating in research while pregnant. These "lessons learned" taught us that active recruitment within this population is a necessity; that is, direct (face-to-face discussions at obstetric appointments) compared with indirect (flyers and general emails) modalities and that prenatal care provider support of the proposed research study is vital to a patient's willingness to participate. By implementation of "lessons learned," we describe how we successfully recruited a similar pregnant population 1 year later. The Clinical Trials related to our article are as follows: 1) Expecting Success: NCT01610752, https://clinicaltrials.gov/ct2/show/NCT01610752; 2) MomEE: NCT01954342, https://clinicaltrials.gov/ct2/show/NCT01954342; and 3) Participate While Pregnant Survey: NCT02699632, https://clinicaltrials.gov/ct2/show/NCT02699632.

    2015-01-01

    Background and Objectives. Pregnancy triggers a wide range of changes in a woman's body leading to various musculoskeletal dysfunctions. Most commonly reported musculoskeletal discomforts by pregnant women are low back pain and symphysis pubis pain. The culture and the environmental factors may influence the discomforts experienced by a pregnant woman. There is a dearth of literature in India, regarding the common musculoskeletal dysfunctions experienced by a pregnant woman, and hence this study. Method. A questionnaire to identify the musculoskeletal dysfunction was developed; content was validated and was translated to local languages through parallel back translation. 261 primiparous pregnant women participated in the study and filled the questionnaire in their native language. Results. Among the musculoskeletal dysfunctions reported by the pregnant women, 64.6% reported calf muscle cramps, 37.1% reported foot pain, and 33.7% experienced low back pain in their third trimester. In the second trimester, common musculoskeletal dysfunctions experienced by the women were that of calf pain (47.8%), low back pain (42%), and pelvic girdle pain (37%). Conclusion. Musculoskeletal dysfunctions and general discomforts very commonly affect the activities of daily living of pregnant women. Understanding the common discomforts during various trimesters of pregnancy will help to develop a comprehensive program for prevention and cure. PMID:25642349

    Obese pregnant women are the focus of numerous dietary and lifestyle intervention studies, however there is a paucity of literature examining the habitual dietary and lifestyle habits of this population. This paper aims to assess maternal dietary and lifestyle habits in an obese cohort, in order to identify priority areas to be addressed in future studies and in clinical practice. This prospective observational study recruited 100 pregnant women with a body mass index 30.0-39.9 kg/m(2) from routine antenatal clinics. Dietary intakes were assessed using a 3-day food diary and a structured lifestyle questionnaire assessed physical activity levels, smoking and alcohol habits and wellbeing. Macronutrient intakes as a percentage of total energy were not compliant to healthy eating guidelines with an inadequate intake of carbohydrate and excess intake of saturated fat. Compliance to recommended intakes of calcium, iron, folate and vitamin D was poor from diet alone. The consumption of energy dense food groups high in fat and sugar was greater than for published pregnant populations and the general female non-pregnant population. One-third of women reported engaging in weekly physical activity that would comply with recommendations for pregnant women while 25 % reported low mood status indicating potential depression. High intakes of energy-dense processed foods and poor compliance to micronutrient recommendations are critical dietary issues of concern among obese pregnant women. Low mood is a barrier to motivation for changing behaviour which would also need to be addressed in future lifestyle intervention studies.

    OBJECTIVE Metformin has been reported to reduce the risk of gestational diabetes (GD) in women with polycystic ovarian syndrome (PCOS). However, little is known about the mechanisms of action of this drug during pregnancy. In the attempt to fill this gap, we performed a prospective longitudinal study providing a detailed examination of glucose and insulin metabolism in pregnant women with PCOS undergoing metformin therapy. RESEARCH DESIGN AND METHODS We enrolled 60 women with PCOS who conceived while undergoing metformin treatment. An oral glucose tolerance test and a euglycemic-hyperinsulinemic clamp were performed at each trimester of gestation in 47 ongoing pregnancies. RESULTS Twenty-two of the study subjects had development of GD despite the treatment. At baseline, insulin sensitivity was comparable between women who had development of GD and women who did not. A progressive decline in this parameter occurred in all subjects, independently of the trimester of GD diagnosis. Insulin secretion was significantly higher during the first trimester in patients with an early failure of metformin treatment. Women with third trimester GD and women with no GD exhibited a significant increase in insulin output as gestation proceeded. All newborns were healthy and only one case of macrosomia was observed. CONCLUSIONS Women with PCOS who enter pregnancy in a condition of severe hyperinsulinemia have development of GD earlier, independently of metformin treatment. The physiologic deterioration of insulin sensitivity is not affected by the drug and does not predict the timing and severity of the glycemic imbalance. Despite the high incidence of GD observed, the drug itself or the intensive monitoring probably accounted for the good neonatal outcome. PMID:23315599

    Objectives Prenatal psychosocial stress has been associated with adverse pregnancy outcomes, even after controlling for known risk factors. This paper aims to evaluate correlates of high perceived stress among Hispanic women, a group with elevated rates of stress during pregnancy. Methods We conducted this analysis among 1426 pregnant Hispanic women using data from Proyecto Buena Salud, a prospective cohort study conducted in Western Massachusetts. Cohen’s Perceived Stress Scale (PSS-14) validated in English and Spanish was administered in early (mean=12.4 wks gestation), mid (mean=21.3 wks gestation) and late (mean=30.8 wks gestation) pregnancy at which time bilingual interviewers collected data on socio-demographic, acculturation, behavioral, and psychosocial factors. High perceived stress was defined as a PSS score>30. Results Young maternal age (odds ratio (OR) =0.6; 95% confidence interval (CI) 0.4-0.9 for <19 vs. 19-23yrs), pre-pregnancy consumption of alcohol (OR=2.2; 95% CI 1.4-3.5 for >12 drinks/mo. vs. none) and smoking (OR=2.2; 95% CI 1.3-3.7 for >10 cigarettes/day vs. none) were associated with high perceived stress during early pregnancy. Furthermore, higher annual household income (OR=0.4; 95% CI 0.1-0.9 for >$30,000 vs. <$15,000), greater number of adults in the household (OR=1.8; 95% CI 1.1-3.0 for ≥3 vs. 1) and language preference (OR=0.6; 95% CI 0.4-0.9 for Spanish vs. English) were associated with high stress during mid-pregnancy. Likewise, annual household income was inversely associated with high stress during late pregnancy. Conclusion Our results have important implications for incorporation of routine screening for psychosocial stress during prenatal visits and implementation of psychosocial counseling services for women at high risk.

    Simple Summary Social licking is often associated with good animal welfare, but little is known about this behavior in cattle. Licking behavior was compared in heifers housed indoors versus on pasture. Licking frequency was four-fold higher when heifers were indoors. However, when considering all social interactions recorded (licking and aggressions) licking events represented about 10% of all interactions regardless of housing. This behavior happened more frequently between heifers that were observed more repeatedly in close vicinity of each other. Provision of smaller indoor floor spaces likely brought animals into closer proximity thus facilitating social interactions. Abstract Housing affects social behaviors, such as competition, but little work has addressed affiliative behaviors. This study compared social licking (SL) in pregnant heifers housed indoors (in a free-stall barn) versus outdoors (on pasture), and relationships with competition, feeding and physical proximity to others. Six heifer groups were observed during two six-hour-periods in both treatments. The total number of social events (SL and agonistic interactions) was four times higher when heifers were housed indoors compared to pasture (546 ± 43 vs. 128 ± 7 events/group; P < 0.05). SL as a ratio of the total number of social events was similar in the two treatments (12% vs. 8% of interactions, free-stall and pasture, respectively; P > 0.05). Housing did not affect how the SL bout was initiated and terminated, the duration, the body part licked and behavior preceding licking (P > 0.05). Animals in close proximity showed higher rates of SL (P < 0.0001) but not agonistic interactions (P > 0.05). A previous agonistic event did not predict occurrence or the role of heifers in the following licking event. The higher stocking density indoors likely resulted in increased social interactions.

    Background: Smoking is considered the most important preventable risk factor in relation to the development of complications during pregnancy and delivery. The aim of this study was to evaluate the effectiveness of an intensive 6-week gold standard programme (GSP) on pregnant women in real life. Methods: This was a prospective cohort study based on data from a national Danish registry on smoking cessation interventions. The study population included 10,682 women of a fertile age. The pregnancy status of the study population was identified using the National Patient Registry. Results: The response rate to follow up was 76%. The continuous abstinence rate for both pregnant and non-pregnant smokers was 24–32%. The following prognostic factors for continuous abstinence were identified: programme format (individual/group), older age, heavy smoking, compliance with the programme, health professional recommendation, and being a disadvantaged smoker. Conclusions: The GSP seems to be as effective among pregnant smokers as among non-pregnant smoking women. Due to the relatively high effect and clinical significance, the GSP would be an attractive element in smoking cessation intervention among pregnant women. PMID:23959083

    Di-(2-ethylhexyl)-phthalate (DEHP) is a ubiquitous environmental pollutant and endocrine disruptor (ED) that causes serious adverse effects on animal and human health. The harmful effects of DEHP on human reproduction are increasingly recognized, especially in women. However, it is not known how endometrial receptivity and embryo implantation, which play important roles in the establishment of pregnancy, are affected by DEHP. This study was aimed towards investigating the effects of DEHP on endometrial receptivity and embryo implantation in pregnant mice. The pregnant mice received DEHP at 0, 250, 500 and 1000 mg/kg/day from day 1 (D1) of gestation until sacrifice. Administration of DEHP led to compromised endometrial receptivity and decreased number of implantation sites. The mRNA and protein expression levels of ERα, PR and E-cadherin, but not those of HoxA10 and MMP-2, were up-regulated by DEHP in the mouse endometrium. The results further suggested that DEHP disrupts the MAPK and NF-κB signaling pathways. This was maybe one of paths which influenced the E-cadherin expression. In conclusion, DEHP reduced endometrial receptivity and impaired embryo implantation by influencing the expression of hormone receptors and E-cadherin. Therefore, determining the full extent of the hazards of DEHP to human reproduction will be vital to developing and implementing effective protective measures.

    Geophagy, the regular and deliberate consumption of soil, is prevalent among pregnant women in sub-Saharan Africa. We examined the associations of geophagy with anemia and helminth infection among 971 human immunodeficiency virus (HIV)-positive pregnant women in Tanzania. About 29% of pregnant women regularly consumed soil. Occupation, marital status, and gestational age were associated with geophagy. Ascaris lumbricoides infection was associated with the prevalence of geophagy (adjusted-prevalence ratio 1.81; 95% confidence interval [CI] = 1.37-2.40); however, hookworm, Trichuris trichiura, and Strongyloides stercoralis showed no association. Anemia and red blood cell characteristics suggestive of iron deficiency were strongly correlated with geophagy at baseline. In longitudinal analyses, we found evidence suggesting that soil consumption may be associated with an increased risk of anemia (adjusted-relative risk 1.16; 95% CI = 0.98-1.36) and a lower hemoglobin concentration (adjusted-mean difference -3.8 g/L; 95% CI [-7.3, -0.4]). Pregnant women should be informed about the potential risks associated with soil consumption.

    Recent in vitro data obtained in our laboratory revealed similarities between baboons and humans in the biotransformation of bupropion (BUP) by both hepatic and placental microsomes. These data supported the use of baboons to study BUP biotransformation during pregnancy. The aim of this investigation was to determine the pharmacokinetics of BUP in baboons during pregnancy and postpartum, as well as fetal exposure to the drug after intravenous administration. Pregnant baboons (n = 5) received a single intravenous bolus dose of bupropion hydrochloride (1 mg/kg) at gestational ages 94-108 days (midpregnancy), 142-156 days (late pregnancy), and 6 weeks postpartum. Blood and urine samples were collected for 12 and 24 hours, respectively. The concentrations of BUP, hydroxybupropion (OH-BUP), threohydrobupropion, and erythrohydrobupropion in plasma were determined by liquid chromatography-tandem mass spectrometry. Relative to the postpartum period, the average midpregnancy clearance of BUP trended higher (3.6 ± 0.15 versus 2.7 ± 0.28 l/h per kg) and the average C(max) (294 ± 91 versus 361 ± 64 ng/ml) and the area under the curve (AUC) of BUP values (288 ± 22 versus 382 ± 42 h·ng/ml) trended lower. AUC(OH-BUP) also tended to be lower midpregnancy compared with postpartum (194 ± 76 versus 353 ± 165 h·ng/ml). Whereas the observed trend toward increased clearance of BUP during baboon pregnancy could be associated with a pregnancy-induced increase in its biotransformation, the trend toward increased renal elimination of OH-BUP may overshadow any corresponding change in the hydroxylation activity of CYP2B.

    Objective. To describe the pharmacokinetics of maraviroc in human immunodeficiency virus (HIV)–infected women during pregnancy and post partum. Methods. HIV-infected pregnant women receiving maraviroc as part of clinical care had intensive steady-state 12-hour pharmacokinetic profiles performed during the third trimester and ≥2 weeks after delivery. Cord blood samples and matching maternal blood samples were taken at delivery. The data were collected in 2 studies: P1026 (United States) and PANNA (Europe). Pharmacokinetic parameters were calculated. Results. Eighteen women were included in the analysis. Most women (12; 67%) received 150 mg of maraviroc twice daily with a protease inhibitor, 2 (11%) received 300 mg twice daily without a protease inhibitor, and 4 (22%) had an alternative regimen. The geometric mean ratios for third-trimester versus postpartum maraviroc were 0.72 (90% confidence interval, .60–.88) for the area under the curve over a dosing interval (AUCtau) and 0.70 (0.58–0.85) for the maximum maraviroc concentration. Only 1 patient showed a trough concentration (Ctrough) below the suggested target of 50 ng/mL, both during pregnancy and post partum. The median ratio of maraviroc cord blood to maternal blood was 0.33 (range, 0.03–0.56). The viral load close to delivery was <50 copies/mL in 13 women (76%). All children were HIV negative at testing. Conclusions. Overall maraviroc exposure during pregnancy was decreased, with a reduction in AUCtau and maximum concentration of about 30%. Ctrough was reduced by 15% but exceeded the minimum Ctrough target concentration. Therefore, the standard adult dose seems sufficient in pregnancy.

    Pregnancy results in many physiologic changes that can alter the pharmacokinetic profiles of medications used during pregnancy. One of the primary factors leading to these pharmacokinetic changes is altered activity of drug-metabolizing enzymes. Ondansetron is a substrate of cytochrome P450 (CYP) 3A4 (primary metabolic pathway), 2D6, and 1A2, all of which are altered during pregnancy. We evaluated the pharmacokinetics of ondansetron at three different gestational time points in a 26-year-old, pregnant, Caucasian woman with normal liver and kidney function, who was maintained on ondansetron 8 mg administered orally 3 times/day throughout her pregnancy. Serial plasma samples were collected from the subject over one 8-hour dosing interval at 14, 24, and 35 weeks' gestation (representing early-, mid-, and late-pregnancy time points, respectively). Ondansetron plasma concentrations were determined using liquid chromatography-tandem mass spectrometry. Ondansetron area under the plasma concentration-time curve decreased progressively across gestation (634 ng hr/ml in early pregnancy, 553 ng hr/ml in mid-pregnancy, and 387 ng hr/ml in late pregnancy), with a corresponding increase in apparent oral clearance (12.6 L/hr in early-pregnancy, 14.5 L/hr in mid-pregnancy, and 20.7 L/hr in late-pregnancy). The decreased area under the plasma concentration-time curve and exposure to ondansetron across gestation is likely due to increased activity of CYP3A4 and CYP2D6 during pregnancy. We were not able to study this patient during the postpartum period; however, as with other CYP3A4 and CYP2D6 substrates, the apparent activities of these isoenzymes are likely return to baseline. To our knowledge, this is the first report to describe ondansetron pharmacokinetics across gestation. Additional pharmacokinetic and pharmacodynamic data are needed to confirm our results and to evaluate clinical impact; however, in the meantime, clinicians should be aware of these pharmacokinetic changes in

    Study objectives: Evaluate the prevalence and phenomenology of dream-associated behaviors affecting pregnant and postpartum mothers. Episodes consist of anxious dreams and nightmares about the new infant that are accompanied by complex behaviors (motor activity, speaking, expressing emotion). Design: Three-group design (postpartum, pregnant, null gravida), self-report, and repeated measures. Setting: Pregnancy and postpartum groups: completion of questionnaires in hospital room within 48 hours of giving birth and home telephone interviews; null gravida group: completion of questionnaires and interview in person or by telephone. Participants: Two hundred seventy-three women in 3 groups: postpartum: n = 202 (mean age = 29.7 ± 4.94 years; 95 primiparas, 107 multiparas); pregnant: n = 50 (mean age = 31.1 ± 5.44 years); null gravida: n = 21 (mean age = 28.5 ± 6.34 years). Interventions: Subjects completed questionnaires about pregnancy and birth factors, personality, and sleep and participated in interviews concerning the prevalence of recent infant dreams and nightmares, associated behaviors, anxiety, depression, and other psychopathologic factors. Measurements and Results: Most women in all groups recalled dreams (88%-91%). Postpartum and pregnant women recalled infant dreams and nightmares with equal prevalence, but more postpartum women reported they contained anxiety (75%) and the infant in peril (73%) than did pregnant women (59%, P < 0.05 and 42%, P < 0.0001). More postpartum (63%) than pregnant (40%) women reported dream-associated behaviors (P < 0.01), but neither group differed from null gravida women (56%). This was due to different distributions over groups of the behavior subtypes. Motor activity was present in twice as many postpartum (57%) as pregnant (24%) or null gravida (25%) women (all P < 0.0001). Expressing emotion was more prevalent among null gravida (56%) than postpartum women (27%) (P < 0.05) but was not different from pregnant women (37

  10. Severe embryotoxicity of artemisinin derivatives in experimental animals, but possibly safe in pregnant women.

    Preclinical studies in rodents have demonstrated that artemisinins, especially injectable artesunate, can induce fetal death and congenital malformations at a low dose range. The embryotoxicity can be induced in those animals only within a narrow window in early embryogenesis. Evidence was presented that the mechanism by which embryotoxicity of artemisinins occurs seems to be limited to fetal erythropoiesis and vasculogenesis/ angiogenesis on the very earliest developing red blood cells, causing severe anemia in the embryos with higher drug peak concentrations. However, this embryotoxicity has not been convincingly observed in clinical trials from 1,837 pregnant women, including 176 patients in the first trimester exposed to an artemisinin agent or artemisinin-based combination therapy (ACT) from 1989 to 2009. In the rodent, the sensitive early red cells are produced synchronously over one day with single or multiple exposures to the drug can result in a high proportion of cell deaths. In contrast, primates required a longer period of treatment of 12 days to induce such embryonic loss. In humans only limited information is available about this stage of red cell development; however, it is known to take place over a longer time period, and it may well be that a limited period of treatment of 2 to 3 days for malaria would not produce serious toxic effects. In addition, current oral intake, the most commonly used route of administration in pregnant women with an ACT, results in lower peak concentration and shorter exposure time of artemisinins that demonstrated that such a concentration-course profile is unlikely to induce the embryotoxicity. When relating the animal and human toxicity of artemisinins, the different drug sensitive period and pharmacokinetic profiles as reviewed in the present report may provide a great margin of safety in the pregnant women.

    Many phthalates, parabens and phenols are suspected to have endocrine-disrupting properties in humans. They are found in consumer products, including food wrapping, cosmetics and building materials. The foetus is particularly vulnerable and exposure to these chemicals therefore is of concern for pregnant women. We investigated current exposure to several commonly used phthalates, parabens and phenols in healthy, pregnant Danish women. A total of 200 spot urine samples were collected between 8 and 30 weeks of gestation and analysed for metabolites of ten phenols, seven parabens and 16 phthalate by liquid chromatography-tandem mass spectrometry representing 26 non-persistent compounds. The majority of analytes were present in the urine sample collected from most women who participated. Thus, in 174 of the 200 women, metabolites of more than 13 (>50%) of 26 compounds were detected simultaneously. The number of compounds detected per woman (either as the parent compound or its metabolite(s)) ranged from 7 to 21 with a median of 16. The majority of compounds correlated positively with each other within and between chemical groups, suggesting combined exposure sources. Estimated daily intakes (DIs) of phthalates and bisphenol A (BPA) were below their individual tolerable DI (TDI) and with hazard quotients below 1. In conclusion, we found detectable levels of phthalate metabolites, parabens and phenols in almost all pregnant women, suggesting combined multiple exposures. Although the estimated DI of phthalates and BPA for an individual was below TDI, our results still raise concern, as current toxicological risk assessments in humans do not take into account simultaneous exposure. The true cumulative risk for the foetus may therefore be underestimated.

    Zika virus presents risk of physical harm to pregnant women, but the fear of infection is also affecting women around the world. There is a gap in the research on Zika virus in the areas involving the impact on the psychosocial well-being of pregnant women. Therefore, this study is aimed at the investigation of the psychosocial adjustment of pregnant women to the risks of Zika virus infection during pregnancy. We investigated 14 pregnant women who were classified in three different groups: six in the first trimester, five in the second trimester and three in the third trimester, aged from 28 to 40 years (33.43 ± 3.76 years). Content analysis was used to interpret data. Our results show that the psychosocial adjustment of participants was significantly negative and included five aspects: (1) negative feelings, (2) changes in family planning, (3) adopting new customs (avoiding places of risk, use of specific clothes and use of repellent), (4) changed attitudes regarding body image and (5) feeling of external demand regarding prevention. The fear of Zika virus infection and all its associated risks have a negative biopsychosocial impact on the pregnant women in this study.

    Background: Quality of life differs for different people in different situations and is related to one's self-satisfaction with life. Quality of life is affected by health status. Objectives: The current study examined the relationship between quality of life and depression in pregnant women in Kashan city. Patients and Methods: A Case - control study was performed on 112 depressed pregnant women (Case Group) and 353 Non-depressed pregnant women (Control Group) who referred to the prenatal health care centers of Kashan University of Medical Sciences .They completed Short Form 36 Health Survey (SF-36) to assess the quality of life and the Beck Depression Inventory to assess the level of depressive symptoms. T-test, chi-square and Pearson correlation coefficient statistical tests were used for data analysis. Results: The findings showed that there was an inverse relationship between quality of life and depression in pregnancy (P = 0.0001). Average scores in all eight domains of quality of life were significantly lower in depressed pregnant women compared to non- depressed women. The strongest relationship was observed between depression and vitality (r =-0.52, P = 0.0001), mental health (r = -0.50, P = 0.001) and social functioning (r =-0.38, P = 0.001). Conclusion: Depressed pregnant women had a lower quality of life. The proper management of depression during pregnancy can improve the quality of life in women. It is recommended that antenatal services integrate screening for depression into routine antenatal care. PMID:25414858

    This study described the nutritional status of 228 pregnant women and the influence of this on birth weight. This is a retrospective study, developed in a health center in the municipality of São Paulo, with data obtained from medical records. Linear regression analysis was carried out. An association was verified between the initial and final nutritional status (p<0.001). The mean of total weight gain in the pregnant women who began the pregnancy underweight was higher compared those who started overweight/obese (p=0.005). Weight gain was insufficient for 43.4% of the pregnant women with adequate initial weight and for 36.4% of all the pregnant women studied. However, 37.1% of those who began the pregnancy overweight/obese finished with excessive weight gain, a condition that ultimately affected almost a quarter of the pregnant women. Anemia and low birth weight were uncommon, however, in the linear regression analysis, birth weight was associated with weight gain (p<0.05). The study highlights the importance of nutritional care before and during pregnancy to promote maternal-infant health.

    Introduction. Intestinal parasitic infections, especially due to helminths, increase anemia in pregnant women. The results of this are low pregnancy weight gain and IUGR, followed by LBW, with its associated greater risks of infection and higher perinatal mortality rates. For these reasons, in the setting of no large previous studies in Venezuela about this problem, a national multicentric study was conducted. Methods. Pregnant women from nine states were studied, a prenatal evaluation with a coproparasitological study. Univariated and multivariated analyses were made to determine risk factors for intestinal parasitosis and related anemia. Results. During 19 months, 1038 pregnant women were included and evaluated. Intestinal parasitosis was evidenced in 73.9%: A lumbricoides 57.0%, T trichiura 36.0%, G lamblia 14.1%, E hystolitica 12.0%, N americanus 8.1%, E vermicularis 6.3%, S stercoralis 3.3%. Relative risk for anemia in those women with intestinal parasitosis was 2.56 (P < .01). Discussion. Intestinal parasitoses could be associated with conditions for development of anemia at pregnancy. These features reflect the need of routine coproparasitological study among pregnant women in rural and endemic zones for intestinal parasites. Further therapeutic and prophylactic protocols are needed. Additional research on pregnant intestinal parasitic infection impact on newborn health is also considered. PMID:17093349

    Objective Intrahepatic cholestasis of pregnancy (ICP) is a rare liver disorder, usually manifesting in the third trimester and associated with increased perinatal morbidity and mortality. The hallmark laboratory abnormality in ICP is elevated fasting serum bile acids; however, there are limited data on whether a nonfasting state affects a pregnant woman's total bile acids. This study assesses fasting and nonfasting bile acid levels in 10 healthy pregnant women after a standardized glucose load to provide insight into the effects of a glucose load on bile acid profiles. Study Design Pilot prospective cohort analysis of serum bile acids in pregnant women. A total of 10 healthy pregnant women from 28 to 32 weeks' gestation were recruited for the study before undergoing a glucose tolerance test. Total serum bile acids were collected for each subject in the overnight fasting state, and 1 and 3 hours after the 100-g glucose load. Results There was a statistically significant difference between fasting versus 3-hour values. There was no statistically significant difference between fasting versus 1-hour and 1-hour versus 3-hour values. Conclusion There is a difference between fasting and nonfasting total serum bile acids after a 100-g glucose load in healthy pregnant women. PMID:26495178

    The objective of this in vitro study was to evaluate and compare the effects of xylazine on basal uterine contractility of bovine pregnant uterine strips and that of lidocaine on xylazine-sensitized bovine pregnant uterine strips, at different stages of pregnancy. Basal contractility was evaluated in an isolated organ bath and the functionality of the strips throughout the experiment was evaluated using a dose of carbachol (10(-5)M). Uterine motility, expressed with amplitude, frequency of contractions as well as the area under the curve, was recorded in different stages of pregnancy and data were collected at 15-min intervals (5-min before and 5-min after xylazine administration and 5-min after lidocaine addition on the plateau contraction induced by xylazine). Uterine motility increased in all the stages of pregnancy after xylazine addition and gradually decreased after treatment with lidocaine. These data suggest that lidocaine might decrease the tonic effect induced by xylazine on bovine pregnant uteri.

    Children in early infancy do not mount effective antibody responses to many vaccines against commons infectious pathogens, which results in a window of increased susceptibility or severity infections. In addition, vaccine-preventable infections are among the leading causes of morbidity in pregnant women. Immunization during pregnancy can generate maternal immune protection as well as elicit the production and transfer of antibodies cross the placenta and via breastfeeding to provide early infant protection. Several successful vaccines are now recommended to all pregnant women worldwide. However, significant gaps exist in our understanding of the efficacy and safety of other vaccines and in women with conditions associated with increased susceptible to high-risk pregnancies. Public acceptance of maternal immunization remained to be improved. Broader success of maternal immunization will rely on the integration of advances in basic science in vaccine design and evaluation and carefully planned clinical trials that are inclusive to pregnant women.

    SUMMARY Introduction: Group B streptococcus (GBS) or Streptococcus agalactiae can colonize the gastrointestinal and genitourinary tracts and has been considered one of the most important risk factors for the development of neonatal disease. The present study evaluated the antimicrobial susceptibility of GBS isolates from pregnant women who were attended at a public health service in Northern Paraná, Brazil. Methods: A descriptive analytical cross-sectional study was performed with 544 pregnant women, at ≥ 35 weeks of gestation. One hundred and thirty-six GBS isolates from pregnant women were tested for antimicrobial susceptibility. Results: All of the GBS isolates showed susceptibility to the drug that is most frequently used for intrapartum prophylaxis: penicillin. Resistance to clindamycin and erythromycin was detected, thus decreasing the options of prophylaxis in women who are allergic to penicillin. Conclusions: Additional studies should be conducted to increase the knowledge of GBS sensitivity profile to antimicrobials in other health centers. PMID:27828624

  20. Improving Nutrition in Pregnant Adolescents: Recommendations for Clinical Practitioners

    PubMed Central

    2003-01-01

    Pregnancy represents an ideal time for health promotion activities. Many women, including adolescents, are interested and willing to change health behaviors to improve the chance that they will deliver a healthy infant. This paper focuses on improving nutrition in pregnant adolescents. Seven recommendations are presented to help achieve this goal: 1) Focus on foods, not nutrients; 2) individualize and work within the pregnant adolescent's current eating habits; 3) consider the context of family and peer groups; 4) reward efforts; 5) make it easy; 6) focus on weight gain patterns for optimal birth outcomes; and 7) refer to a dietician, as needed. Use of these recommendations comprehensively addresses adolescent developmental needs to improve nutrition during pregnancy. These recommendations are not meant to be all-inclusive; rather, they are meant to serve as a guide for clinical management of nutrition for pregnant adolescents. PMID:17273337

  1. Should all pregnant women be screened for syphilis?

    2007-09-01

    In industrialized countries, the incidence of syphilis has decreased dramatically since the discovery of penicillin in the 1940s. However, syphilis and congenital syphilis are far from eradicated, especially in low- and middle-income countries. Syphilis in pregnant women is a cause of adverse pregnancy outcomes that can be prevented by screening for syphilis and early treatment in pregnancy. Several studies have found screening of pregnant women for syphilis to be a highly cost-effective intervention, even if the prevalence of syphilis is low. Obstacles to universal screening of pregnant women include low awareness of syphilis and low quality of antenatal care and healthcare in general in many low- and middle-income countries. For these settings, we need simpler and more reliable serological tests for syphilis, but we also need to strengthen health services in general to ensure sustainable antenatal care services to ensure sustainability of syphilis screening programmes.

    Abstract Chronic hepatitis B is a worldwide disease, with significant burden on health care systems. While universal vaccination programs have led to an overall decrease in incidence of transmission of hepatitis B, unfortunately, there remain large areas in the world where vaccination against hepatitis B is not practiced. In addition, vertical transmission of hepatitis B persists as a major concern. Hepatitis B treatment of the pregnant patient requires a thorough assessment of disease activity and close monitoring for flares, regardless of initiation of antiviral therapy. We discuss, in this article, the current and emergent strategies which aim to reduce the rate of transmission of hepatitis B from the pregnant mother to the infant and we review the updated guidelines regarding management of liver disease in pregnant women with hepatitis B.

    The current research targets 4 potential stereotypes driving hostile attitudes and discriminatory behaviors toward pregnant women: incompetence, lack of commitment, inflexibility, and need for accommodation. We tested the relative efficacy of reducing concerns related to each of the stereotypes in a field experiment in which female confederates who sometimes wore pregnancy prostheses applied for jobs in a retail setting. As expected, ratings from 3 perspectives (applicants, observers, and independent coders) converged to show that pregnant applicants received more interpersonal hostility than did nonpregnant applicants. However, when hiring managers received (vs. did not receive) counterstereotypic information about certain pregnancy-related stereotypes (particularly lack of commitment and inflexibility), managers displayed significantly less interpersonal discrimination. Explicit comparisons of counterstereotypic information shed light on the fact that certain information may be more effective in reducing discrimination than others. We conclude by discussing how the current research makes novel theoretical contributions and describe some practical organizational implications for understanding and improving the experiences of pregnant workers.

    Parabens have been used in multiple products including personal care products, pharmaceuticals, and foods for more than 50 years but increasing numbers of studies have raised concerns on their safety. The present study was designed to determine urinary paraben levels among pregnant women and their matching newborn infants (<48 h after delivery), and the association between paraben levels and stress markers. Pregnant women (n=46) and their matching newborn infants were recruited from four university hospitals located in Seoul, Ansan and Jeju of Korea, 2011. Parabens including methyl paraben (MP), ethyl paraben (EP), n-propyl paraben (PP), and n-butyl paraben (BP) were measured in the urine using an automatic, high throughput online SPE-LC-MS/MS method. Urinary concentrations were normalized with specific gravity (SG). Free cortisol, malondealdehyde (MDA) and 8-hydroxydeoxyguanosine (8-OHdG) were measured in the urine as stress marker. Urinary MP was detected as the highest, and BP was detected as the lowest paraben in the urine samples of both pregnant women and their infants. Significant correlations between paraben concentrations of maternal and their newborn infant's urine were observed. The levels of urinary parabens among Korean pregnant women are comparable to those reported elsewhere, except for EP which were 4-9 folds higher than pregnant women of other countries. The ratios of infant to maternal urinary paraben concentrations varied between 0.5 and 0.6 for MP and PP, but approximately 10 fold lower for EP. Urinary MP or EP levels were associated with several oxidative stress related biomarkers such as urinary 8-OHdG and MDA, even after the adjustment of relevant covariates such as maternal age, mode of delivery, pre-pregnancy BMI, gestational age and parity. This is the first study that reported the levels of major parabens in the first urine of newborn infants. Further studies are warranted to understand the implications of paraben exposure among

    To assess support for 12 potential smoking cessation strategies among pregnant Australian Indigenous women and their antenatal care providers. Cross-sectional surveys of staff and women in antenatal services providing care for Indigenous women in the Northern Territory and New South Wales, Australia. Respondents were asked to indicate the extent to which each of a list of possible strategies would be helpful in supporting pregnant Indigenous women to quit smoking. Current smokers (n = 121) were less positive about the potential effectiveness of most of the 12 strategies than the providers (n = 127). For example, family support was considered helpful by 64 % of smokers and 91 % of providers; between 56 and 62 % of smokers considered advice and support from midwives, doctors or Aboriginal Health Workers likely to be helpful, compared to 85-90 % of providers. Rewards for quitting were considered helpful by 63 % of smokers and 56 % of providers, with smokers rating them more highly and providers rating them lower, than most other strategies. Quitline was least popular for both. This study is the first to explore views of pregnant Australian Indigenous women and their antenatal care providers on strategies to support smoking cessation. It has identified strategies which are acceptable to both providers and Indigenous women, and therefore have potential for implementation in routine care. Further research to explore their feasibility in real world settings, uptake by pregnant women and actual impact on smoking outcomes is urgently needed given the high prevalence of smoking among pregnant Indigenous women.

    Self-concept has been recognized and researched as a powerful variable in relation to teenage pregnancy. Low self-concept frequently has been identified as a cause and consequence of teenage pregnancy as well as a factor in participation and compliance with health care recommendations. Most of the research on self-concept and teenage pregnancy occurred in the 1970s to mid-1980s, and all found lower self-concept in pregnant and parenting teens when compared with their nonpregnant contemporaries and normative data. This study found the opposite to be true. The 126 pregnant and parenting teens in this study had higher self-concepts than the reported normative group. Also, important variations in self-concept were found in relation to sociodemographics. This potentially suggests that what was once known about this aggregate is no longer true, and a reinvestigation is warranted. The purpose of this study was to reinvestigate the self-concept of pregnant and parenting teens and compare them with published normative data and to examine the relationship between sociodemographics and self-concept. The study employed a survey methodology. Data were analyzed using frequencies, percentages, measures of central tendency and dispersion, t test, chi-square test, and analysis of variance. This study found that pregnant and parenting teens had a higher self-concept than the normative data on nonpregnant teens reported by the research instrument authors. Furthermore, this older sample of pregnant and parenting teens (mean age, 17.83 years) had self-concepts more similar to the junior high school normative sample than their senior high school-age contemporaries. Also, this study found that self-concept varies according to the pregnant and parenting teens; ages, years of schooling, types of schools attended, income sources, and receipt of public assistance. This study has implications for health care providers, health and public educators, and nursing researchers in terms of program

    Like antibacterial agents, antiparasite drugs for pregnant women and children must be chosen in function of the stage of pregnancy, age of the child, and expected benefit-risk ratio. While no agent is totally safe, there are few absolute contraindications. Most zones of serious endemic parasite disease are located in developing countries where parasite, bacterial, or viral conditions combined with poor nutrition treatment make it necessary to treat disease in a complex pathogenic environment that weakens pregnant women and children with multiple parasite infections. In both temperate and tropical zones, there have been few real therapeutic advances involving release of new products on the market or development of new indications for existing products. Constant appearance and extension of hematozoa resistance to conventional and even more recent antimalarial agents have prompted research to find new active drugs and long-lasting treatment combinations. Real therapeutic breakthroughs have resulted from the need to develop safe drugs without substantial side-effects for single-dose use in control programs against endemic parasite diseases in mass populations including pregnant women and young children in tropical zones. There are several notable examples in the field of major verminous diseases. Ivermectin is a versatile drug that can be used against filariasis as well as for management of intestinal worms or ectoparasitosis in temperate and tropical countries. Praziquantel is an important advance in platyhelminthiasis, especially bilharziais. Triclabendazole, the latest addition to the benzimidazole family, has shown promise as a substitute for bithionol, that is difficult to procure and not recommended in pregnant women, for treatment distomiasis occurring in pregnant women and children. Other examples include albendazole against giardiasis, nitazoxamide against cryptosporidiosis, artemisinine against bilharziasis, and paramomycine, not recommended in pregnant women

    Objective Physical activity generally declines during pregnancy, but barriers to activity during this time period are not well understood. The objective was to examine barriers to physical activity in a large cohort of pregnant women and to explore these barriers in more depth with qualitative data derived from a separate focus group study using a socioecologic framework. Method A total of 1535 pregnant women (27–30 weeks’ gestation) enrolled in the Pregnancy, Infection, and Nutrition Study were asked an open-ended question about their primary barrier to physical activity; responses were coded into categories according to the socioecologic framework. To further elucidate, 13 focus groups of a total of 58 pregnant women (20–37 weeks’ gestation) were conducted among Hispanic, African American, and White participants. Results Among the 1535 pregnant women participating in the survey, 85% reported an intrapersonal barrier to physical activity, of which almost two-thirds were health related. Only 2% of the women reported their main barrier to physical activity as interpersonal and 3% reported a neighborhood or environmental barrier. These results were supported by the focus group data, overall and by race/ethnicity and body mass index. Although women discussed barriers to physical activity at a variety of levels, the intrapersonal level was the most frequently cited and discussed factor in both studies. Conclusions Since pregnancy may trigger the development of obesity and since physical activity is recommended for healthy pregnant women, it is imperative to promote physical activity in a more relevant way. These quantitative and qualitative studies revealed many barriers to physical activity among pregnant women and some suggestions for interventions. PMID:18478322

    AIM To investigate choroidal thickness in pregnant women and compare the measurements with those of normal nonpregnant women. METHODS Using enhanced depth imaging optical coherence tomography (EDI-OCT), choroidal thickness was measured at the fovea and at 1 mm and 3 mm superior, inferior, temporal, and nasal to the fovea in both healthy pregnant women and nonpregnant women. Pearson correlation analysis was performed to evaluate the relationships between subfoveal choroidal thickness (SFCT) and the demographic and ocular parameters. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using fixed-effects model when Meta-analyses were conducted. RESULTS Comparison of choroidal thickness between the groups showed that it was significantly greater in healthy pregnant women's eyes than in normal nonpregnant women's eyes at all locations except at 3 mm superior and 3 mm temporal from the fovea (P<0.05). The mean SFCT was 344.13±50.94 µm in healthy pregnant women's eyes and 315.03±60.57 µm in normal nonpregnant women's eyes, with a statistically significant difference (P=0.008). Pearson correlation analysis showed that age and axial length were significantly related to SFCT in healthy pregnant women, normal nonpregnant women, and all subjects. The results of our cross-sectional study were consistent with the results of the further Meta-analysis, with a pooled weighted mean difference (WMD) of 33.66 µm (95% CI: 26.16 to 41.15) for SFCT. CONCLUSION Our results, along with the comprehensive Meta-analysis, suggest that choroidal thickness in healthy pregnant women is greater than that in normal nonpregnant women. PMID:27588276

    Thyroid hormones are essential for fetal development. Normal thyroid function in pregnant women adjusts by itself in cases of pregnancy, phenomenon that is deficient in cases of previous maternal thyroid disease. The study group was represented by 120 females, with reproductive age, with known thyroid disease, that had a up to delivery pregnancy. Thyroid ultrasound parameters and functional parameters were follow-up during the 9-month of gestation. The study proposes a mathematical model of predicting the need and the amount of tetraiodothyronine treatment in pregnant women with prevalent thyroid disease.

    In Morocco, the seroprevalence of toxoplasmosis in pregnant women living in Rabat, was estimated by analyzing antibodies (IgG, IgM) levels using an ELISA test. The analysis of 2456 serums at the Institut National d'Hygiène showed that the seroprevalence of toxoplasmosis is about 50.6%. According to the questionnaire, the lack of knowledge about this disease and soil contact could be the main causes of toxoplasmosis infection. The use of IgG avidity test has excluded a recent infection in 93.5% of pregnant women with IgM positive sera.

    Benefits of physical exercise on the physical and psychological health lead to specifics guidelines during pregnancy. For pregnant women, to take part in aerobics exercise (walking, biking) (i.e. 30 minutes, three times per week at 60-90% of the maximal heart rate) and strength training (i.e. one to two times per week) is recommended. Physical exercise programs during pregnancy have shown benefits for preventing and treating complications pregnancy (e.g. gestational diabetes mellitus, overweight). Benefits of exercise and risks associated with sedentary should be widely diffused among pregnant women and prenatal caregivers.

    Anti N-methyl-D-aspartate (NMDA) receptor encephalitis is one of the most common types of autoimmune synaptic encephalitis. Anti-NMDA receptor encephalitis commonly occurs in young women with ovarian teratoma. It has variable clinical manifestations and treatment responses. Sometimes it is misdiagnosed as a psychiatric disorder or viral encephalitis. To the best of our knowledge, anti-NMDA receptor encephalitis is a rare condition in pregnant women. We report a case of anti-NMDA receptor encephalitis in a pregnant woman who presented with abnormal behavior, epileptic seizure, and hypoventilation.

No clinical symptoms of infection of this system were observed in particular trimesters of pregnancy. It was found that, despite the lack of symptoms of the urinary tract infection, the infection as such did occur-most frequently in the 2nd trimester. The most common bacteria in pregnant women with insulin-dependent diabetes (lasting over 10 years) were Staphylococcus epidermidis and Staphylococcus saprophiticus.

    In this paper, we introduce a study that we carried out in order to validate the use of a simplified pregnant woman model for the assessment of the fetus exposure to radio frequency waves. This simplified model, based on the use of a homogeneous tissue to replace most of the inner organs of the virtual mother, would allow us to deal with many issues that are raised because of the lack of pregnant woman models for numerical dosimetry. Using specific absorption rate comparisons, we show that this model could be used to estimate the fetus exposure to plane waves.

    Heavy alcohol consumption during pregnancy has been associated with retardation of fetal growth and abnormal fetal development. Pregnant women whose offspring are at risk because of alcohol abuse can be identified and counselled by health professional providing prenatal care. Offspring born to women who had been drinking heavily and subsequently abstained from or reduced their intake of alcohol before the third trimester demonstrated improvements in growth and in regulation of sleep-awake states. The existing health care delivery system can be modified in a cost-effective manner to treat pregnant women who are problem drinkers. Physicians' attitudes and behaviour are critical for the success of this strategy. PMID:7272865

    Bacterial vaginosis (BV), candidiasis, and trichomoniasis were the three established types of vaginal conditions until aerobic vaginitis (AV) was defined in the early 2000s. We sought to study the prevalence of abnormal vaginal flora (AVF) with inflammation in our hospital and to correlate it with AV. We prospectively collected vaginal smear specimens originated from symptomatic women who were examined at Iaso Obstetrics, Gynecology and Children's Hospital of Athens from April 2014 until September 2015. Amsel's criteria were used for the diagnosis of BV. The presence of leukocytes and lactobacillary grade were evaluated to classify a condition as AVF with inflammation; subsequently, bacterial cultures were performed. A total of 761 women were included. Five hundred and seventy-nine women were diagnosed with candidiasis, BV, trichomoniasis, or other types of vaginitis in which no pathogenic bacterial growth occurred in cultures. One hundred and eighty-two women (23.9 %) were diagnosed with AVF with inflammation (116 non-pregnant, 66 pregnant). Escherichia coli was the most common pathogen among these women (non-pregnant: 45.7 %, pregnant: 34.8 %). Other common pathogens were Group-B-Streptococcus (non-pregnant: 20.7 %, pregnant: 22.7 % respectively), Enterococcus faecalis (14.7 %, 18.2 %), and Klebsiella pneumoniae (6.9 %, 12.1 %). The prevalence of AVF with inflammation may be high. Since inflammation criteria were applied, most cases of BV were eliminated and the majority of cases of AVF are AV. Therefore, clinicians should include AV in the differential diagnosis of vaginitis, while microbiologists should take into account the growth of aerobic bacteria in vaginal cultures originating from women with microscopic findings of AV.

    RU 486 is a synthetic steroid which acts as an antiprogestin at the receptor level. The clinical usefulness of the compound for menstrual regulation and termination of early pregnancy is currently being evaluated. The aim of the present study was to determine the plasma levels of RU 486 following the oral administration of the compound to 42 pregnant and 10 non-pregnant women. The levels of RU 486 were measured by a radioimmunoassay method which uses chromatography on Sephadex LH 20 columns. The identity of the compound assayed as RU 486 was confirmed, but the presence of small amounts of two highly cross-reacting metabolites (monodemethyl and didemethyl RU 486) in the analyzed fractions could not be excluded. Following the ingestion of a single tablet containing 25 and 50 mg of the compound, a peak plasma value of approximately 3.5 to 4.0 mumol/l in both the pregnant and non-pregnant subjects was reached one to two hours later. The half-lives of elimination were about 20 hours in both the pregnant and the non-pregnant women. Following the repeated oral administration of 50, 100 or 200 mg of RU 486 daily for four days, maximum plasma levels of 2.9, 4.5 and 5.4 mumol/l, respectively, were found. Thus, the increase in plasma levels was not directly proportional to the increase in the dose. No accumulation of RU 486 in the plasma was found, even when the duration of treatment was prolonged to six days. The data partly explain the reported lack of relation between ingested dose and frequency of induced abortion and they may be useful for designing future studies on the use of compound to prevent implantation, induce menstruation or terminate an early pregnancy.

    Objectives To determine the prevalence of sexually transmitted infections (STIs) and other reproductive tract infections (RTIs) among pregnant women in Moshi, Tanzania and to compare the occurrence of STIs/RTIs among human immunodeficiency virus (HIV)-infected and uninfected women. Methods Pregnant women in their 3rd trimester (N = 2654) were recruited from two primary health care clinics between June 2002 and March 2004. They were interviewed, examined and genital and blood samples were collected for diagnosis of STIs/RTIs and HIV. Results The prevalence of HIV, active syphilis and herpes simplex virus – type 2 (HSV-2) were 6.9%, 0.9% and 33.6%, respectively, while 0.5% were positive for N gonorrhoeae, 5.0% for T vaginalis and 20.9% for bacterial vaginosis. Genital tract infections were more prevalent in HIV-seropositive than seronegative women, statistically significant for syphilis (3.3% vs 0.7%), HSV-2 (43.2% vs 32.0%), genital ulcers (4.4% vs 1.4%) and bacterial vaginosis (37.2% vs 19.6%). In comparison with published data, a declining trend for curable STIs/RTIs (syphilis, trichomoniasis and bacterial vaginosis) was noted. Conclusion Rates of STIs and RTIs are still high among pregnant women in Moshi. Where resources allow, routine screening and treatment of STIs/RTIs in the antenatal care setting should be offered. Higher STIs/RTIs in HIV-seropositive women supports the expansion of HIV-counseling and testing services to all centers offering antenatal care. After identification, STIs/RTIs need to be aggressively addressed in HIV-seropositive women, both at antenatal and antiretroviral therapy care clinics. PMID:19243592

    Introduction: Toxoplasma gondii (T. gondii) is an intracellular protozoan that can infect all mammals, who serve as intermediate host. It causes congenital, neurological, eyes complications and mild or asymptomatic infections in humans. Purpose of this study: To investigate not only the prevalence of T. gondii, but also to find out its genotyping using multiple sequential molecular methods to predict exactly the precise genotyping of T. gondii among Saudi pregnant women. Methods: A cross-sectional study was conducted using multi-stage methods. Initial stage involved enrolment of 250 Saudi pregnant women from multi-centre healthcare and community based settings in the capital of Saudi Arabia Riyadh. The second stage was embracement of the laboratory investigation that included Enzyme immunoassay (ELISA), DNA extraction, PCR, nested-PCR assay, and genotyping of the seropositive cases. Results: 203 women agreed to take part in our study with a response rate of 81.2% (203/250). Using ELISA, we found that the prevalence of Toxoplasma gondii IgG and IgM antibodies was 32.5% and 6.4%, respectively. We found that 29 samples (80.6%) were of genotype II; however 7 samples (19.4%) were of genotype III. Conclusion: Defining the population structure of T. gondii from Saudi Arabia has important implications for transmission, immunogenicity, pathogenesis, and in planning preventive strategies. Relationship between such variation in structure and disease manifestation in pregnant women is still difficult to assess due to the role of host immune status and genetic background on the control of infection, and of other parasitic features such as the infecting dose or parasite stage. Our finding of the genotyping of T. gondii might facilitate and inform future studies on comparative genomics and identification of genes that control important biological phenotypes including pathogenesis and transmission among Saudi women.

    Background Studies on salivary variables and pregnancy in Latin America are scarce. This study aimed to compare salivary flow rate, pH, and concentrations of calcium, phosphate, and sIgA of unstimulated whole saliva in pregnant and non-pregnant Brazilians. Methods Cross-sectional study. Sample was composed by 22 pregnant and 22 non-pregnant women attending the Obstetrics and Gynecology Clinics, São Lucas Hospital, in Porto Alegre city, South region of Brazil. Unstimulated whole saliva was collected to determine salivary flow rate, pH, and biochemical composition. Data were analyzed by Student t test and ANCOVA (two-tailed α = 0.05). Results No difference was found for salivary flow rates and concentrations of total calcium and phosphate between pregnant and non-pregnant women (p > 0.05). Pregnant women had lower pH (6.7) than non-pregnant women (7.5) (p < 0.001), but higher sIgA level (118.9 mg/L) than the latter (90.1 mg/L) (p = 0.026). Conclusion Some of the tested variables of unstimulated whole saliva were different between pregnant and non-pregnant Brazilians in this sample. Overall, the values of the tested salivary parameters were within the range of international references of normality. PMID:17132167

    Recent evidence has indicated that bacteria-derived extracellular vesicles (EVs) are important for host–microbe communication. The aims of the present study were to evaluate whether bacteria-derived EVs are excreted via the urinary tract and to compare the composition of bacteria-derived EVs in the urine of pregnant and non-pregnant women. Seventy-three non-pregnant and seventy-four pregnant women were enrolled from Dankook University and Ewha Womans University hospitals. DNA was extracted from urine EVs after EV isolation using the differential centrifugation method. 16S ribosomal RNA (16S rRNA) gene sequencing was performed using high-throughput 454 pyrosequencing after amplification of the V1–V3 region of the 16S rDNA. The composition of 13 taxa differed significantly between the pregnant and non-pregnant women. At the genus level, Bacillus spp. EVs were more significantly enriched in the urine of the pregnant women than in that of the non-pregnant women (45.61% vs 0.12%, respectively). However, Pseudomonas spp. EVs were more dominant in non-pregnant women than in pregnant women (13.2% vs 4.09%, respectively). Regarding the compositional difference between pregnant women with normal and preterm delivery, EVs derived from Ureaplasma spp. and the family Veillonellaceae (including Megasphaera spp.) were more abundant in the urine of preterm-delivered women than in that of women with normal deliveries. Taken together, these data showed that Bacillus spp. EVs predominate in the urine of pregnant women, whereas Pseudomonas spp. EVs predominate in the urine of non-pregnant women; this suggests that Bacillus spp. EVs might have an important role in the maintenance of pregnancy.

At the genus level, Bacillus spp. EVs were more significantly enriched in the urine of the pregnant women than in that of the non-pregnant women (45.61% vs 0.12%, respectively). However, Pseudomonas spp. EVs were more dominant in non-pregnant women than in pregnant women (13.2% vs 4.09%, respectively). Regarding the compositional difference between pregnant women with normal and preterm delivery, EVs derived from Ureaplasma spp. and the family Veillonellaceae (including Megasphaera spp.) were more abundant in the urine of preterm-delivered women than in that of women with normal deliveries. Taken together, these data showed that Bacillus spp. EVs predominate in the urine of pregnant women, whereas Pseudomonas spp. EVs predominate in the urine of non-pregnant women; this suggests that Bacillus spp. EVs might have an important role in the maintenance of pregnancy.

    Background: The healthcare and socio-economic burden resulting from influenza A (H1N1) pdm09 in Spain was considerable. Our aim was to estimate and compare the management (resource utilization) and economic healthcare impact in an at-risk group of unvaccinated pregnant women with an unvaccinated group of non-pregnant woman of childbearing age (15–44 yr old). Methods: We addressed this question with a longitudinal, observational, multicentre study. Inputs were the requirements in managing both groups of women. Outcome measures were healthcare costs. Direct healthcare (including medical utilisation, prescriptions of antivirals, medication, diagnostic tests, and hospitalisation) costs and indirect (productivity loss) costs were considered. Unit of cost was attributed to the frequency of health service resources utilisation. The mean cost per patient was calculated in this group of women. Results: We found that the influenza clinical pattern was worse in non-pregnant women as they had a high medical risk of 20.4% versus 6.1% of pregnant women. Non-pregnant required more antipyretics and antibiotics, and needed more health service resource utilisation (338 medical visits in non-pregnant women vs. 42 in pregnant women). The total cost of non-pregnant women was higher (€4,689.4/non-pregnant and €2,945.07/pregnant). Conclusions: Cost per (H1N1) pdm09 was lower for pregnant women, probably due to more preventive measures adopted for their protection in Spain. The highest costs were incurred by hospitalisations/day and work absenteeism for non-pregnant than for pregnant women. These data will allow better future pandemic influenza planning. PMID:27252911

    Background Vaginal yeast infection refers to irritation of the vagina due to the presence of opportunistic yeast of the genus Candida (mostly Candida albicans). About 75% of women will have at least one episode of vaginal yeast infection during their lifetime. Several studies have shown that pregnancy and uncontrolled diabetes increase the infection risk. Reproductive hormone fluctuations during pregnancy and elevated glucose levels characteristic of diabetes provide the carbon needed for Candida overgrowth and infection. The goal of this study was to determine the prevalence of vaginal yeast infection among pregnant women with and without diabetes. Methods This was a case-control study using cases reports from Kepala Batas Health Clinic, Penang State, Malaysia from 2006 to 2012. In total, 740 pregnant ladies were chosen as sample of which 370 were diabetic and 370 were non-diabetic cases. Results No relationship between diabetes and the occurrence of vaginal yeast infection in pregnant women was detected, and there was no significant association between infection and age group, race or education level. Conclusion In conclusion, within radius of this study, vaginal yeast infection can occur randomly in pregnant women. PMID:27540323

  17. Pregnant Women in Louisiana Are Not Meeting Dietary Seafood Recommendations

    PubMed Central

    Lammi-Keefe, C. J.

    2016-01-01

    Background. The 2015–2020 Dietary Guidelines for Americans recommend that pregnant women and women of childbearing ages consume 8–12 oz. of seafood per week. Fish are the major dietary source of omega-3 long chain polyunsaturated fatty acids, which have benefits for the mother and fetus. Methods. In this observational study, we investigated dietary habits of pregnant women in Baton Rouge, Louisiana, USA, to determine if they achieve recommended seafood intake. A print survey, which included commonly consumed foods from protein sources (beef, chicken, pork, and fish), was completed by pregnant women at a single-day hospital convention for expecting families in October 2015. Women (n = 221) chose from six predefined responses to answer how frequently they were consuming each food. Results. Chicken was consumed most frequently (75% of women), followed by beef (71%), pork (65%), and fish (22%), respectively. Consumption frequency for the most consumed fish (catfish, once per month) was similar to or lower than that of the least consumed beef, chicken, and pork foods. Consumption frequency for the most consumed chicken and beef foods was at least once per week. Conclusion. Our data indicate that pregnant women in Louisiana often consume protein sources other than fish and likely fail to meet dietary seafood recommendations. PMID:27504202

    Background and Objective: Vitamin D deficiency during pregnancy is a worldwide problem. Studies have reported prevalence ranged 18-84% in pregnant women. Receiving adequate calcium and vitamin D during pregnancy period is necessary for calcium homeostasis, fetal growth and bone mineralization. This study was aimed to determine the prevalence of vitamin D deficiency in pregnant women and their neonates in Shahroud city in the northeast Iran. Methods: In this cross-sectional study, 284 pregnant women and their neonates referred to Fatemiyeh Hospital of Shahroud were included. Blood samples of mothers and umbilical cords were collected during the delivery and were sent to laboratory in order to measure calcium and 25-hydroxy vitamin D. Findings: Amounts of Vitamin D insufficiency (20-30 ng/mL) and deficiency (<20 ng/mL) in (mothers, neonates) were found to be (60.2%, 48.9%) and (1.1%, 2.5%) respectively. Calcium deficiency (<8.5 mg/dL) was present in 33.5% of mothers and 25% of neonates. There was a weak correlation between maternal serum and cord blood 25-hydroxy vitamin D (r=0.12, p=0.053). Conclusion: More than half of the mothers and their neonates had some degrees of vitamin D deficiency. It is recommended to evaluate the nutritional status of vitamin D in pregnant women along with public health interventions to be carried out. PMID:27157170

    2016-02-04

    Vitamin D deficiency has emerged as a public health problem worldwide due to its important role in health and disease. The present work is intended to examine prevalence of vitamin D deficiency among pregnant Saudi women and related risk factors. A cross-sectional study was carried out at King Fahad Medical City in Riyadh, Saudi Arabia. Serum 25-hydroxy vitamin D (25(OH)D) was measured by enzyme-linked immunosorbent assay in 160 pregnant women during the first trimester of pregnancy. Socio-demographic, lifestyle and maternal characteristics were collected and vitamin D intake was assessed using a 24-h dietary recall. Weight and height were measured using standardized methods. Vitamin D deficiency (25(OH)D < 50 nmol/L) and insufficiency (25(OH)D = 50-74 nmol/L) were reported in 50% and 43.8% of the study sample, respectively. Median serum 25(OH)D concentration was 49.9 nmol/L. Adequate vitamin D intake (≥600 IU/day) was reported among only 8.1% of pregnant women. Age group, educational level, sun exposure frequency and daytime and daily practice of exercise were significantly associated with vitamin D status. Overall, vitamin D deficiency was common among pregnant Saudi women in Riyadh. Steps should be taken to address the current situation, including increased sunlight exposure, consumption of fatty fish, and vitamin D supplements.

    Background While hepatitis E virus (HEV) mostly causes self-limited disease in general population, it is more severe in pregnant women. Objectives This study aimed to investigate the seroprevalence of anti-HEV IgG among a population of pregnant women in West Azerbaijan of Iran . Patients and Methods One hundred thirty six pregnant women referred to urban health centers of Urmia for pursuing pregnancy-related health services were enrolled in a descriptive, cross-sectional study. Anti-HEV IgG antibody was evaluated using enzyme-linked immunosorbent assay (enzyme-linked immunosorbent assay, ELISA; Dia.Pro; Diagnostic Bioprobes). Results Only five (3.6%) of 136 cases had positive results for anti-HEV IgG. There was no significant difference between age (P=0.88), and income level (P = 0.19) of the two seropositive and seronegative groups. All seropositive cases were from urban areas. Conclusions The seroprevalence of anti-HEV IgG is low in the population of pregnant women in , similar to the rates reported from developed countries. Effective health services and provision of safe water supplies in Urmia may take role in this low prevalence rate. PMID:24348644

    In this study concentration level of calcium, cadmium, copper, iron, magnesium, manganese, nickel, lead and zinc were determined in the amniotic fluid of pregnant women, aged 15 - 45 years enrolled at the Obafemi Awolowo University Teaching Hospitals Complex Ile - Ife. This was with a view to predict the body burden of the metals in the pregnant women and assess the health implications of the toxic elements to the pregnant women and their fetuses. Fifty samples of the amniotic fluid were collected from the pregnant women. The efficiency of extraction of trace metals using conventional wet acid digestion method (CDM) and microwave induced acid digestion method (MWD) was determined by recovery experiments. Levels of trace metals were determined using Atomic Absorption Spectrophotometry. The high percentage recoveries obtained from MWD made it a more efficient method than the CDM and hence its adoption for sample digestion. Statistical analysis of data using descriptive and inferential statistics revealed that age; education and profession have effects on the levels of the trace metals. The mean levels of most of the toxic metals obtained in this study were lower than the recommended limits of trace metals in women whole blood.

    The purpose was to determine if running 30 m/min on a 10 degrees incline, 60 min/day for 5 days/ week altered fetal glycogen storage in prepregnancy trained rats. Animals that exercised for 3 weeks prior to pregnancy either continued the same exercise program until Day 19 of gestation (pregnant running group [PR]), or ceased exercising at conception (pregnant controls [PC]). A separate set of animals did not exercise either before or during pregnancy (pregnant nonrunning control group [PNRC]). On Day 20 of gestation, fetal organs and placenta were weighted and analyzed for glycogen concentration. Glycogen concentrations were not different in either fetal liver, heart, or placenta of PR rats compared to PNRC animals. However, fetal liver glycogen concentration was significantly lower in the fetal heart and liver of PC animals compared to glycogen measured in both PNRC and PR animals (p < .05). These results suggest that exercise of this intensity does not compromise fetal glycogen storage in trained pregnant rats. However, chronic prepregnancy exercise and then abrupt cessation of exercise at conception may compromise fetal growth and development.

  19. Increased Glyburide Clearance in the Pregnant Mouse Model

    PubMed Central

    Zhou, Lin; Zhang, Yi; Hebert, Mary F.; Unadkat, Jashvant D.

    2010-01-01

    Glyburide (GLB) is an oral sulfonylurea, commonly used for the treatment of gestational diabetes mellitus. It has been reported that the clearance of GLB in pregnant women is significantly higher than that in nonpregnant women. The molecular mechanism by which pregnancy increases the clearance of GLB is not known, but it may be caused by increased CYP3A activity. Because liver tissue from pregnant women is not readily available, in the present study, we investigated the mechanism of such pregnancy-related changes in GLB disposition in a mouse model. We demonstrated that the systemic clearance of GLB in pregnant mice was increased approximately 2-fold (p < 0.01) compared with nonpregnant mice, a magnitude of change similar to that observed in the clinical study. Plasma protein binding of GLB in mice was not altered by pregnancy. The half-life of GLB depletion in hepatic S-9 fractions of pregnant mice was significantly shorter than that of nonpregnant mice. Moreover, GLB depletion was markedly inhibited by ketoconazole, a potent inhibitor of mouse Cyp3a, suggesting that GLB metabolism in mice is primarily mediated by hepatic Cyp3a. These data suggest that the increased systemic clearance of GLB in pregnant mice is likely caused by an increase in hepatic Cyp3a activity during pregnancy, and they provide a basis for further mechanistic understanding and analysis of pregnancy-induced alterations in the disposition of GLB and drugs that are predominantly and extensively metabolized by CYP3A/Cyp3a.

    2008-03-01

    Herpes simplex virus type 2 (HSV-2) is considered as a major co-factor of both sexual transmission and acquisition of the human immunodeficiency virus (HIV). The HIV epidemic in Senegal is characterized by a remarkable and stable low prevalence. Whether HSV-2 may also constitute a possible co-factor favouring the spreading of HIV epidemic in Senegal is yet unknown. This prompted us to evaluate the HSV-2 seroprevalence in the sentinel population of pregnant women in Senegal. Two hundred and sixty pregnant women attending Roi Baudouin maternity in the capital city Dakar (n = 14; 135) and the antenatal clinic in Kaolack (n = 125), the third city of Senegal, were prospectively recruited between March and August 2003. Fifty-six women (22%) were positive for HSV-2 serology. The prevalence of HSV-2 seropositivity was higher in women living in Dakar (26%) than in those living in Kaolack (16%) (P < 0.01). Only two women from Dakar and two other from Kaolack were found to be HIV-1-infected. Our observations suggest a seemingly low seroprevalence of HSV-2 infection in adult women Senegal, comparable with those usually reported in Western countries. Further, epidemiological surveys are needed to confirm these results in the general population.

    Aim To determine the prevalence rate and resistance profile of Streptococcus agalactiae (S. agalactiae) in vaginal swabs of pregnant and adult non-pregnant women in the Tuzla region, Bosnia and Herzegovina (B&H), as well as its association with other aerobic bacteria. Methods This prospective study included 200 women, 100 pregnant and 100 adult non-pregnant. The research was conducted at the Institute of Microbiology, University Clinical Center Tuzla from October to December 2015. Standard aerobic microbiological techniques were used for isolation and identification of S. agalactiae and other aerobic bacteria. Antimicrobial susceptibility was determined by the disk diffusion and microdilution method(VITEK 2/AES instrument). Results Among 200 vaginal swabs, 17 (8.50%) were positive for S. agalactiae, e. g., 7% (7/100) of pregnant and 10% (10/100) of adult non-pregnant women. In the pregnant group, 71.4% (5/7) of S. agalactiae isolates were susceptible to clindamycin and 85.7%(6/7) to erythromycin. In the adult non-pregnant group, only resistance to clindamycin was observed in one patient (1/10; 10%). S. agalactiae as single pathogen was isolated in 57.14% (4/7) of pregnant and 60% (6/10) of adult non-pregnant S. agalactiae positive women. In mixed microbial cultures S. agalactiae was most frequently associated with Enterococcus faecalis and Escherichia coli. Conclusion The rate of S. agalactiae positive women in the population of pregnant and adult non-pregnant women of Tuzla Canton, B&H is comparable with other European countries. Large studies are needed to develop a common national strategy for the prevention of S. agalactiae infection in B&H, especially during pregnancy.

    Insulin resistance (IR) has been reported to play an important role in recurrent spontaneous abortion (RSA) among patients with polycystic ovary syndrome (PCOS). However, scanted materials exist regarding the independent effect of IR on RSA. The aim of this study is to investigate the status of IR in first trimester pregnant patients with normal pre-pregnant glucose tolerance and history of RSA. This two-center case-control study enrolled totally 626 first trimester pregnant women including 161 patients with a history of recurrent spontaneous abortion, who were pre-pregnantly glucose-tolerant according to oral glucose tolerance test (OGTT), and 465 women with no history of abnormal pregnancies of any kind. Clinical, biochemical and hormonal parameters were simultaneously measured in all participants. Serum beta-HCG, estradiol, progesterone, fasting plasma glucose and fasting plasma insulin levels, as well, the calculated homeostasis model assessment of insulin resistance index (HOMA-IR), fasting plasma glucose/insulin ratio(G/I) and pregnancy outcome were analyzed and compared. Serum beta-HCG and progesterone were found to be significantly lower in RSA group compared to controls. Subjects in RSA group were found to have higher HOMA-IR and lower G/I ratio than those in control group. Serum beta-HCG and progesterone were negatively correlated with HOMA-IR, and positively with G/I ratio even after adjustment for BMI. The spontaneous abortion rate within first trimester pregnancy of RSA patients was significantly higher than that in controls. In conclusion, woman with recurrent spontaneous abortion and normal pre-pregnant glucose metabolism tends to be more insulin resistant during first trimester pregnancy than healthy controls, no matter whether she has PCOS or not. Insulin resistance might be one of the direct causes that lead to recurrent abortion.

    Dietary deficiency in iron and to a lesser extent folic acid is the principle cause of anemia in the world. Reproductive aged women and growing children are the principle groups at risk of anemia. About half of nonpregnant reproductive aged women in tropical countries have hemoglobin levels lower than 12 g/100 ml, the level used by the World Health Organization to define anemia. Nutritional anemia is even more widespread among pregnant and lactating women because of the increased needs for iron during those periods. Pregnant women need almost 500 mg of iron for their increased red blood cell mass, 220 mg for routine iron loss through the urine, bile, sweat, and other routes; 290 mg for the fetus, and almost 25 mg for the placenta. In all, the pregnant women theoretically requires over 1000 mg of iron through diet or bodily reserves. Healthy, well-nourished women have total iron reserves of 2500 mg, but according to published data almost 2/3 of pregnant women even in favorable circumstances end their pregnancies with no remaining iron reserves. In tropical regions the lack of iron reserves is aggravated by parasites and infections, closely spaced pregnancies that do not allow restoration of reserves, and poor dietary availability of iron. Anemia during pregnancy is associated with elevated risks of maternal morbidity and mortality. Fatigue, dyspnea, palpitations and tachycardia, vertigo, loss of appetite and cravings for soil or other inappropriate substances are frequently observed in anemic women. The risks of prematurity and low weight are increased for infants of anemic women. Fetal malformation may be associated with folic acid deficiency. Nutrition education is needed for pregnant women. Local foods may be enriched with iron, and pregnant women may be given iron and vitamin B12 supplements directly. Iron supplements may rapidly increase iron reserves, but they are poorly tolerated by many women. The supplements should be avoided if possible early in the

    An oxidative burst occurs during pregnancy due to the large consumption of oxygen in the tissues and an increase in metabolic demands in response to maternal physiological changes and fetal growth. This study aimed to determine the oxidative profile and activity of δ-aminolevulinate dehydratase (δ-ALA-D) in pregnant women who received iron supplementation. Oxidative stress parameters were evaluated in 25 pregnant women with iron supplementation, 25 pregnant women without supplementation and 25 non-pregnant women. The following oxidative stress parameters were evaluated: thiobarbituric acid reactive substances (TBARS), protein thiol groups (P-SH), non-protein thiol levels (NP-SH), vitamin C levels, catalase and δ-ALA-D activity. Markers of oxidative stress and cell damage, such as TBARS in plasma were significantly higher in pregnant women without supplementation. Levels of P-SH, NP-SH and δ-ALA-D activity were significantly lower in pregnant women without supplementation compared to non-pregnant and pregnant women with supplementation, while vitamin C levels were significantly lower in pregnant women without supplementation when compared to non-pregnant women. The increase in the generation of oxidative species and decrease of antioxidants suggest the loss of physiological oxidative balance during normal pregnancy, which was not observed in pregnant women with iron supplementation, suggesting a protective effect of iron against oxidative damage.

    We aimed to evaluate the diagnostic accuracy of serum D-dimer levels in pregnant women with adnexal torsion (AT). The pregnant women with ovarian cysts who suffered from pelvic pain were divided into two groups; the first group consisted of the cases with surgically proven as AT (n = 17) and the second group consisted of the cases whose pain were resolved in the course of follow-up period without required surgery (n = 34). The clinical characteristics and serum D-dimer levels were compared between the groups. Patients with AT had a higher rate of elevated serum white blood cell (WBC) count (57% vs. 16%, p = 0.04) and serum D-dimer levels (77% vs. 21%, p < 0.01) on admission in the study group than in the control group. Elevated D-dimer and cyst diameter larger than 5 cm yielded highest sensitivity (82% for each); whereas the presence of nausea and vomiting and elevated CRP had the highest specificity (85% and 88%, respectively). This is the first study that evaluates the serum D-dimer levels in humans in the diagnosis of AT, and our findings supported the use of D-dimer for the early diagnosis of AT in pregnant women.

    Genital human papillomavirus (HPV) infection is the most common sexually transmitted infection. Most HPV infections are benign and resolve on their own, but some women develop persistent HPV infections. Persistent HPV infection with certain high-risk HPV genotypes is the necessary cause of most epithelial lesions of the uterine cervix. The importance of latent or quiescent HPV, waning immunity, hormonal milieu, microbiota, and other factors modifying the natural history of HPV infections across a woman's lifetime deserves further study. Promising biomarkers are emerging that may aid in defining which HPV-infected women are at risk of developing invasive cervical cancer.

    As women and families join the ranks of the homeless in increasing numbers, many women find themselves confronting both pregnancy and homelessness. When pregnancy accompanies the precarious state of homelessness, the need for adequate shelter is not being met during one of the most critical periods of a woman's life. This article focuses on the unique health needs of homeless pregnant women. Detailed accounts of the daily life experiences of African American, Anglo, and Latina homeless pregnant women were derived from an ethnographic study conducted in a large metropolitan area in southern California. Their pregnancies were difficult because normal physiological changes of pregnancy often became pathological, signs of potential complications went unnoticed or unattended, and minor discomforts of pregnancy were exacerbated by the women's environment. Nursing therapeutics that support health maintenance and coping strategies of the women while on the streets or in shelters were explicated.

    Urinary excretion of free and total (free plus conjugated) forms of methyl, ethyl, n-propyl and n-butyl parabens (MP, EP, PP and BP, respectively) and their metabolite p-hydroxybenzoic acid were measured for 111 pregnant Japanese women. Frequent detection of parabens and their metabolite indicated that exposure takes place daily for pregnant Japanese women. The estrogenic potency of PP was 20 times higher than those of the other 3 parabens for the present subjects when both abundance in the urine and the relative estrogenic activity of each compound was considered. Detection of free parabens suggested dermal exposure, probably from their inclusion in personal care products. No statistical association was found between the anogenital index (birth weight-adjusted AGD) of male offspring and the concentrations of any parabens in the urine of the mothers suggesting that the parabens were not apparently estrogenically active at the exposure level of the present subjects.

    This study examines the decisions of rural pregnant women who sought obstetric care elsewhere, especially in an urban area. The principal data source was the "Patients' Survey of 1988", a nationwide data collection. Among 4091 rural pregnant women, 3090 women left their home counties for obstetric care; 1946 women went to small or medium-sized cities, 645 to large cities. Multivariate techniques were used to examine the factors related to selecting urban obstetric care. The analysis shows that younger, abnormally delivered women were more likely to seek urban obstetrical facilities. In addition, medical insurance, the number of registered cars/1000, the number of general hospitals in the county, and the distance to the nearest large city were positively related to the decision to go to any city. However, distance to the nearest small or medium-sized city had a negatively significant effect on urban obstetrical service utilization. (author's modified)

    The aim of this study was to systematically review the safety and efficacy of inhaled beclomethasone for asthma treatment in pregnant women. We performed a systematic review in Medline, LILACS and SciELO electronic databases in December 2012. A total of 3433 articles were found by using the keywords asthma, pregnancy and beclomethasone. Among these, 1666 were from Medline, via PubMed, and 1767 were from LILACS and SciELO. Nine of these articles were selected. Only one paper suggested an increased foetal risk for congenital malformations, and one other for offspring endocrine and metabolic disturbances. Data are mostly reassuring, supporting the use of glucocorticoid inhalants during pregnancy, and we found no evidence of inferiority in relation to efficacy and safety of beclomethasone compared to other drugs used in pregnant asthmatic women.

    The Internet is an innovative strategy to increase public participation. It is important to include pregnant and parenting teens' perspectives when planning programs to meet their needs. This qualitative study explored online discussions as a strategy to enhance participation by this population. Findings showed that online communication was preferred over face-to-face group discussions. Being anonymous online encouraged open and honest feedback. Participants experienced various forms of social support, however, there was an overall lack of teen involvement online. Strategies to engage adolescents in online discussions and reduce barriers are discussed. Strategies included the use of teen moderators, home computer access, technical support, and engagement in naturally flowing online discussions to meet social support needs. Blending researchers' with teens' needs for social support in an online environment is encouraged. With careful planning and design, online communications can result in mutual benefits for researchers, service providers, and pregnant and parenting adolescents.

    A 32-year-old patient who was 17 weeks of pregnant referred to our hospital due to a lesion on the eyelid and swelling on her face. Patient's history revealed that she helped her husband for slaughtering of a sick animal and contacted with the meat. A scabby lesion was detected on the inferior eyelid with hyperaemia around, central necrotic appearance and swelling. The diagnosis of anthrax was performed based on her epidemiological data, physical examination findings, and Bacillus anthracis were seen on direct preparation. This case was considered worthy to present since she was pregnant, the disease was located on the inferior eyelid, which is a rare place for location, and caused no complication or sequel either in mother or in baby.

    A two-year-old pregnant Gordon setter presented with acute onset of flaccid tetraparesis and respiratory distress. Neurological examination revealed diffuse lower motor neuron dysfunction. Clostridium botulinum neurotoxin B was isolated from the dog's serum. The dog was hospitalised and received supportive care; respiratory function was monitored but positive-pressure ventilation was not required. Recovery was complete within 1 month and parturition occurred without complication 49 days after admission. The puppies delivered lacked any obvious congenital defects and development during the first few months of life was normal. The source of contamination was suspected to be poorly conserved dry food. To the authors' knowledge, this is the first report of C. botulinum neurotoxin B isolation in a dog and the first report of botulism in a pregnant bitch.

    Introduction Pregnancy during the adolescent period is challenging mainly because of the nutritional demands of both the adolescent and pregnancy period. The risk for anaemia increases especially in developing countries such as Ghana where malaria is endemic and the practice of pica is common. In this study, we sought to determine the prevalence of anaemia, pica practice and malaria infection among pregnant adolescent girls and assess the extent to which these factors are associated. Methods Two hundred and sixty five (265) pregnant adolescent girls were recruited from three hospitals in Accra. Haemoglobin levels, malaria infection and the practice of pica were assessed. Pearson's Chi squared tests were used to determine associations and logistic regression analysis was used to determine the odds of being anaemic. Significance was set at p≤0.05. Results Anaemia prevalence was 76% with severity ranging from mild (47.8%) to severe (0.8%). About 27.5% were moderately anaemic. Pica was practiced in only 9.1% of the girls. Malaria infection was prevalent in 17.7% of the girls. The logistic regression analysis indicated that pregnant girls with malaria infection were 3.56 times more likely to be anaemic when compared to those without malaria. Also, those who practiced pica were 1.23 times more likely to be anaemic when compared to those who did not practice pica. Conclusion Anaemia is very prevalent in pregnant adolescent girls and is a public health problem. Drastic measures should be taken to reduce the high prevalence. PMID:27642435

    In the pregnant patient when visualization of the ureters is requested, excretory urography is often ordered. We propose the use of digital radiography using single exposure as an alternative to conventional urography. This technique allows significant dose reduction while visualizing the entire urinary tract. It can be performed on most current-generation computerized tomographic scanners. In addition to dose reduction, the ability to manipulate, magnify, and avoid repeat exposures makes this an attractive alternative to the conventional film-screen technique.

    This paper reports the ethnographic findings from a study of cannabis use by pregnant women in rural Jamaica. The perceived functions of ganja in reducing the physiological symptoms of pregnancy and associated psychological stress are described in relation to the sociocultural context of pregnancy in low-income rural communities. The data suggest that distinguishing life-style characteristics of cannabis-smoking women may actually mitigate the potentially harmful effects of marihuana.

  19. Listeriosis Prevention Knowledge Among Pregnant Women in the USA

    2005-01-01

    Background: Listeriosis is a food-borne disease often associated with ready-to-eat foods. It usually causes mild febrile gastrointestinal illness in immunocompetent persons. In pregnant women, it may cause more severe infection and often crosses the placenta to infect the fetus, resulting in miscarriage, fetal death or neonatal morbidity. Simple precautions during pregnancy can prevent listeriosis. However, many women are unaware of these precautions and listeriosis education is often omitted from prenatal care. Methods: Volunteer pregnant women were recruited to complete a questionnaire to assess their knowledge of listeriosis and its prevention, in two separate studies. One study was a nationalmore » survey of 403 women from throughout the USA, and the other survey was limited to 286 Minnesota residents. Results: In the multi-state survey, 74 of 403 respondents (18%) had some knowledge of listeriosis, compared with 43 of 286 (15%) respondents to the Minnesota survey. The majority of respondents reported hearing about listeriosis from a medical professional. In the multi-state survey, 33% of respondents knew listeriosis could be prevented by not eating delicatessen meats, compared with 17% in the Minnesota survey ( p = 0.01). Similarly, 31% of respondents to the multi-state survey compared with 19% of Minnesota survey respondents knew listeriosis could be prevented by avoiding unpasteurized dairy products (p = 0.05). As for preventive behaviors, 18% of US and 23% of Minnesota respondents reported avoiding delicatessen meats and ready-to-eat foods during pregnancy, whereas 86% and 88%, respectively, avoided unpasteurized dairy products. Conclusions: Most pregnant women have limited knowledge of listeriosis prevention. Even though most respondents avoided eating unpasteurized dairy products, they were unaware of the risk associated with ready-to-eat foods. Improved education of pregnant women regarding the risk and sources of listeriosis in pregnancy is needed.« less

    Abstract Aims This study estimated the prevalence of twenty-two 12-month and lifetime psychiatric disorders in a sample of 744 low-income pregnant women and the frequency that women with psychiatric disorders received treatment. Method To identify psychiatric disorders, the Diagnostic Interview Schedule (DIS) was administered to Medicaid or Medicaid-eligible pregnant women enrolled in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC). The sample was stratified by the rural or urban location of the WIC sites in southeastern Missouri and the city of St. Louis. Eligible women were enrolled at each site until their numbers were proportional to the racial distribution of African American and Caucasian pregnant women served there. Results The 12-month prevalence of one or more psychiatric disorders was 30.9%. Most common were affective disorders (13.6%), particularly major depressive disorder (8.2%) and bipolar I disorder (5.2%). Only 24.3% of those with a psychiatric disorder reported that they received treatment in the past year. Lifetime prevalence of at least one disorder was 45.6%, with affective disorders being the most frequent (23.5%). Caucasian women were more likely than African Americans to have at least one 12-month disorder, with the difference largely accounted for by nicotine dependence. Higher prevalence of lifetime disorders was also found in Caucasian women, particularly affective disorders and substance use disorders. There were no differences in the prevalence of 12-month or lifetime psychiatric disorders by the urban or rural residence of subjects. Conclusions With nearly one third of pregnant women meeting criteria for a 12-month psychiatric disorder and only one fourth receiving any type of mental health treatment, comprehensive psychiatric screening during pregnancy is needed along with appropriate treatment.

    Background Smoking during pregnancy has deleterious health effects for the fetus and mother. Given the high risks associated with smoking in pregnancy, smoking cessation programs that are designed specifically for pregnant smokers are needed. This paper summarizes the current landscape of mHealth cessation programs aimed at pregnant smokers and where available reviews evidence to support their use. Methods A search strategy was conducted in June–August 2015 to identify mHealth programs with at least one component or activity that was explicitly directed at smoking cessation assistance for pregnant women. The search for text messaging programs and applications included keyword searches within public health and medical databases of peer-reviewed literature, Google Play/iTunes stores, and gray literature via Google. Results Five unique short message service programs and two mobile applications were identified and reviewed. Little evidence was identified to support their use. Common tools and features identified included the ability to set your quit date, ability to track smoking status, ability to get help during cravings, referral to quitline, and tailored content for the individual participant. The theoretical approach utilized was varied, and approximately half of the programs included pregnancy-related content, in addition to cessation content. With one exception, the mHealth programs identified were found to have low enrollment. Conclusion Globally, there are a handful of applications and text-based mHealth programs available for pregnant smokers. Future studies are needed that examine the efficacy of such programs, as well as strategies to best promote enrollment. PMID:27110146

    There have been an association between systemic diseases and hormonal changes particularly diabetes which has been cited as a risk factor in the progression of periodontitis in pregnant women. The incidence and severity of periodontal diseases are increasing at a higher rate and a common condition in pregnant diabetic women among Bangladeshi population. This cross sectional study included 200 pregnant women who were selected from gynecological department and examined at the dental unit. The clinical parameters used were the Silness and Loe plaque index (PI), gingival scores and periodontal status and any relationship to socio demographic variables (age, occupation, level of education and urban or rural residence) and clinical variables (gestation period, previous pregnancy, type of diabetes and periodontal maintenance) were evaluated. The results showed that these clinical parameters increased concomitantly with an increase in the stage of pregnancy and in women with multiple pregnancies. Increased age, lower level of education, unemployment and patients residing in rural areas were associated with significantly higher gingival scores and periodontal measures. Women with increased age and multiple pregnancies usually have less interest to frequent periodontal maintenance showing a significant statistical relation between an increased age and changes in gingival and periodontal status; however no significant association was found between increased age and plaque index. It is concluded that gingival inflammatory symptoms are aggravated during pregnancy in diabetic women and are related to different clinical and demographic variables.

    Objective The bidirectional nature of mother-child interaction is widely acknowledged during infancy and childhood. Prevailing models during pregnancy focus on unidirectional influences exerted by the pregnant woman on the developing fetus. Prior work has indicated that the fetus also affects the pregnant woman. Our objective was to determine whether a maternal psychophysiological response to stimulation of the fetus could be isolated. Methods Using a longitudinal design, an airborne auditory stimulus was used to elicit a fetal heart rate and motor response at 24 (n = 47) and 36 weeks (n = 45) gestation. Women were blind to condition (stimulus versus sham). Maternal parameters included cardiac (heart rate) and electrodermal (skin conductance) responses. Multilevel modeling of repeated measures with 5 data points per second was used to examine fetal and maternal responses. Results As expected, compared to a sham condition, the stimulus generated a fetal motor response at both gestational ages, consistent with a mild fetal startle. Fetal stimulation was associated with significant, transient slowing of maternal heart rate coupled with increased skin conductance within 10 s of the stimulus at both gestational ages. Nulliparous women showed greater electrodermal responsiveness. The magnitude of the fetal motor response significantly corresponded to the maternal skin conductance response at 5, 10, 15, and 30 s following stimulation. Conclusion Elicited fetal movement exerts an independent influence on the maternal autonomic nervous system. This finding contributes to current models of the dyadic relationship during pregnancy between fetus and pregnant woman. PMID:24119937

    Managing orthopedic conditions in pregnant patients leads to challenges that must be carefully considered so that the safety of both the mother and the fetus is maintained. Both perioperative and intraoperative considerations must be made based on physiologic changes during pregnancy, risks of radiation, and recommendations for monitoring. Operative timing, imaging, and medication selection are also factors that may vary based on trimester and clinical scenario. Pregnancy introduces unique parameters that can result in undesirable outcomes for both mother and fetus if not handled appropriately. Ultimately, pregnant patients offer a distinct challenge to the orthopedic surgeon in that the well-being of 2 patients must be considered in all aspects of care. In addition, not only does pregnancy affect the management of orthopedic conditions but the pregnant state also causes physiologic changes that may actually induce various pathologies. These pregnancy-related orthopedic conditions can interfere with an otherwise healthy pregnancy and should be recognized as possible complications. Although the management of orthopedic conditions in pregnancy is often conservative, pregnancy does not necessarily preclude safely treating pathologies operatively. When surgery is considered, regional anesthesia provides less overall drug exposure to the fetus and less variability in fetal heart rate. Intraoperative fluoroscopy can be used when appropriate, with 360° fetal shielding if possible. Lateral decubitus positioning is ideal to prevent hypotension associated with compression of the inferior vena cava.

    Fifty years ago, when a woman became pregnant, she was expected to stop working. Today, however, most women who work are the primary, sole, or co-breadwinner for their families, and their earnings during pregnancy are often essential to their families' economic well-being. Medical data about working during pregnancy are sparse but generally show that both low-risk and high-risk women can tolerate work-related duties well, although some work accommodations (eg, providing a chair for sitting, allowing snacks, or modifying the work schedule) may be necessary. However, some employers refuse to accommodate pregnant women who need adjustments. This can result in a woman being forced to make the choice between working without accommodations and losing her income and health insurance or even her job. Prenatal care providers can play an important role by implementing changes in their own practice, shaping public policy, and conducting research to increase protections for pregnant women and to ensure that they receive medically recommended accommodations while continuing to earn income for their growing families.

    Background and purpose While remifentanil can be used either during labour or fetal surgery, more should be known about the transplacental transfer of this opioid. The aim of this study was to investigate the placental transfer and haemodynamic effects of remifentanil after i.v. administration to pregnant ewes. Experimental approach Seven pregnant ewes received a continuous infusion of remifentanil (0.33 µg·kg−1·min−1) for 1 h, and maternal and fetal arterial blood samples were drawn at regular intervals during and up to 1 h after the discontinuation of the infusion. Haemodynamic parameters were monitored continuously. Blood gas samples were drawn at baseline and once during the infusion. Key results Peak maternal remifentanil plasma levels of 4.0 ± 0.9 ng·mL−1 (mean ± SD) and peak fetal plasma levels of 0.4 ± 0.3 ng·mL−1 were obtained. Remifentanil plasma levels dropped rapidly after the discontinuation of the infusion. The continuous infusion of remifentanil did not result in significant maternal or fetal haemodynamic changes. Conclusions and implications Remifentanil rapidly passes through the placenta of pregnant ewes and although remifentanil concentrations stay significantly lower in the fetus compared with those in the mother, remifentanil can be detected in significant amounts in the fetus.

    The objective of the study was to survey non-pregnant women regarding their preference for obstetric delivery route and to assess their awareness of the maternal and fetal risks of obstetric delivery. We wished to determine the percentage of non-pregnant women who would choose elective cesarean section and to correlate demographic factors. We compared women who elected cesarean delivery versus vaginal delivery. All patients presenting for routine gynecologic care were asked to complete an anonymous survey. Demographic variables analyzed were patient age, race, employment, insurance type and household income. Secondary data regarding knowledge of the risks and benefits of cesarean and vaginal delivery were assessed with a Likert Scale. Of patients surveyed, 13.3% preferred cesarean section. The only significant demographic factor was was race, with 21.7% of non-whites and 7.8% of whites choosing cesarean section. Most patients agreed that elective cesarean sections should be performed and reimbursed by insurance. The majority of women answered neutral regarding the maternal and neonatal risks of obstetrical delivery. The unique feature of this observational study is the sole participation of non-pregnant patients. The percentage of women who would elect cesarean section has significant public health implications. The only difference noted between demographic groups is that non-white women had a stronger preference for cesarean. Without counseling, most women are unsure of the risks of delivery route on maternal and neonatal health.

The sample consisted of 73 Latina adolescent females between the ages of 14 and 20 who were referred to a community-based organization for case management, education, and psychosocial support for pregnant and parenting adolescents. They completed the Conflict Tactics Scale (CTS-2) as part of a pretest to evaluate this intervention program. A small number (12 out of 73; 16%) reported no use of aggressive conflict tactics. Eighty-four percent (61 out of 73) of the study respondents reported using at least one form of minor psychological aggression and 62% (45 out of 73) reported using at least one form of minor physical assault over the past 6 months. Mutuality of conflict was high, especially in cases of minor assault by partner. There was no difference in severity or chronicity of conflict between those who were pregnant and those who were not. Female respondents reported that they and their partners engaged in comparable levels of sexual coercion. Discussion of the context of psychological, physical, and sexual aggression in adolescent relationships suggests alternative approaches to prevention of intimate partner violence among adolescents.

    There are limited data on acute HIV infection (AHI) prevalence during pregnancy. Malawian pregnant women admitted in the third trimester and meeting eligibility criteria underwent dual HIV rapid antibody testing. AHI prevalence was retrospectively detected through HIV RNA pooling of seronegative plasma. Among 3,825 pregnant women screened, dual HIV rapid testing indicated that 30.2% were HIV positive, 69.7% were HIV negative, and 0.1% were indeterminate. Sensitivity and specificity of dual rapid testing was 99.0% and 98.7%, respectively. Of 2,666 seronegative specimens, 2,327 had samples available for HIV RNA pooling; 5 women (0.21%) (95% confidence interval, 0.03-0.40%) had AHI with a median peripartum viral load of 1,324,766 copies/mL. Pregnant women are at risk for AHI, warranting counseling of all women and their sexual partners about incident HIV during pregnancy. Dual HIV rapid tests have high sensitivity and specificity. HIV testing should be repeated in the third trimester and/or at delivery.

    The nature, impact, and treatment of substance use during pregnancy are well described for women living in urban settings. Less is known about pregnant substance-using women living in rural communities. The objective of this review is to describe the existing evidence for the management of substance use in pregnant women living in rural areas. A systematic review of the literature was conducted using PubMed, Embase, and the Cochrane Database of Systematic Reviews, and the quality of the evidence was assessed using the GRADE system. Twenty-two articles that met the inclusion criteria were identified. Descriptive studies document high rates of smoking, marijuana, and polysubstance use among rural, substance-using pregnant women compared to their urban counterparts. Management of substance use disorders is limited by access to and acceptability of treatment modalities. Several innovative, integrated addiction and prenatal care programs have been developed, which may serve as models for management of substance use during pregnancy in rural settings. PMID:27375357

    Currently, at least 18,000 women die every year in Indonesia due to pregnancy or childbirth. It means that every half hour a woman dies due to pregnancy or childbirth. As a result, every year 36,000 children became orphans. The high maternal mortality rate was put Indonesia on top in ASEAN. The main causes of maternal mortality are high-risk pregnancy. Mothers who have diseases like high blood pressure, pre-eclampsia, diabetes, hyperthyroidism, and already over 40 years old and infectious diseases such as rubella, hepatitis and HIV can be factors that lead to high-risk pregnancy. This paper will discuss the development of a blood pressure monitoring device that is suitable for pregnant women. It is based on convenience for pregnant women to get the equipment that is flexible with her presence. Results indicate that the equipment is in use daily support for pregnant women therefore, one of the causes of maternal mortality can be detected earlier.

    Toxoplasmosis is caused by an intracellular protozoan, Toxoplasma gondii, which has a wide geographical distribution. The congenital form results in a gestational form that can present a temporary parasiteamia that will infect the fetus. For this reason early diagnosis in pregnancy is highly desirable, allowing prompt intervention in cases of infection. The aim of this study was to determine the seroprevalence of Toxoplasma gondii antibodies among pregnant women attending the Douala General Hospital. The study was carried out between March and July 2009, whereby 110 pregnant women were tested for IgG and IgM antibodies and information about eating habits and hygienic conditions was collected using a questionnaire. These women's ages ranged from 20–44 years old with an average of 29.9 years; the overall IgG and IgM seroprevalence was 70% and 2.73 % respectively. Seroprevalence was significantly high amongst women who ate raw vegetables (76.39%, P<0.05) and there was a significant trend towards a higher seroprevalence in women who did not have a good source of water (75.58%, P<0.05). This research showed that consumption of raw vegetables and poor quality drinking water are two risk factors associated with Toxoplasma gondii infection amongst pregnant women attending the Douala General Hospital in Cameroon.

    ObjectivesTo describe the degree of annoyance caused by air pollution and noise in pregnant women in a birth cohort; to determine the modifying factors and their relation with exposure to ambient nitrogen dioxide (NO 2). MethodsThe study population was 855 pregnant women in Valencia, Spain. Annoyance caused by air pollution and noise, and explanatory factors were obtained from 786 pregnant women through a questionnaire. NO 2 levels were determined combining measurements at 93 points within the area of study and using geostatistical techniques (kriging). ResultsIn all 7.9% of the women reported high annoyance caused by air pollution and 13.1% high annoyance caused by noise. There was a significant difference in the degree of annoyance due to both air pollution and noise depending on the area where the women lived and their working status. The degree of annoyance correlated better with measured NO 2 at the municipality level (air pollution: r=0.53; noise: r=0.44) than at the individual level (air pollution and noise: r=0.21). On multivariate analysis, being a housewife, higher NO 2 levels and high traffic density were associated with higher degrees of annoyance. ConclusionsThere was a high percentage of women who perceived medium-high annoyance due to noise and air pollution. Annoyance caused by environmental pollutants could lead to some psychological effects, which impair the quality of life, or even physiological ones, which affect prenatal development.

    The aim this study was to determine the in vitro susceptibility to fosfomycin of bacteria isolated from urine samples of pregnant women with urinary tract infection. Samples of urine culture with bacterial growth of pregnant women were collected from clinical laboratories in Tubarão, state of Santa Catarina, Brazil, between September 2012 and May 2013. In the experimental stage, the colonies were tested for sensitivity to fosfomycin by using the Kirby-Bauer method. The following information relating to the samples was also collected: patients' age, colony count, type(s) of identified bacterial(s) and result of the antimicrobial sensitivity test. Student's t-test was used for mean comparison. A total of 134 samples were selected for the study. The age of the subjects ranged from 15 to 40 years (mean 26.7). Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive) were the most commonly identified species. In 89% of cases, the microorganisms were sensitive to fosfomycin. E. coli and S. aureus were the main species of bacteria responsible for urinary tract infections in women in the study area. The most prevalent microorganisms in pregnant women with urinary tract infection were susceptible to fosfomycin.

    Based on the theory of social representations, a qualitative investigation was conducted in order to assess social representations in oral heath in pregnant mothers living in an urban environment. Twenty-eight pregnant adult women attending a prenatal program at a health institution in the city of Medellín, Colombia, were interviewed. The interviews were recorded and transcribed; analysis was performed through open, axial and selective coding, in line with grounded theory. Findings revealed that although pregnant mothers are not greatly concerned about oral health after birth and in early childhood, it increases in importance during growth and development of the child when, besides chewing and feeding aspects, it acquires a socially important role. Analysis revealed how social representations anchored in tradition, with new elements from health professional discourses as well as mass media influences coexist in mothers in an urban environment. These include the close relationship between oral health and teeth, health linked to healthy practices as well as recourse to health services and oral health as a social advantage, related to esthetic aspects.

    Our study revealed that refugee status increases the risks and worsens the outcome of pregnancy among Georgian refugees. 125 Georgian refugee women participated in this study. The study included examinations of the psychological status of expecting mothers, clinical development of pregnancy, complications of labor, functional status of the fetus, and EEG and neuro-ultrasound data of newborns. The control group comprised 125 pregnant women who experienced no stress during pregnancy. An examination of the psycho-emotional status of pregnant refugee women revealed high percentage indicators (82%) for hypochondria, depression, psychopathy, hysteria and psychoastenia in contrast to the control group. The deterioration of psycho-emotional status and biochemical indicators in pregnant refugee women was directly proportional to the worsening of functional and clinical conditions in fetuses. Prolonged stress is the cause of increased morbidity and mortality during pregnancy and child birth in refugee women. Infants born to refugee women also faced increased risks and belong to the group of special premature care and observation.

    Carbon monoxide (CO) is the leading cause of death due to poisoning. Although uncommon, CO poisoning does occur during pregnancy and can result in fetal mortality and neurological malformations in fetuses who survive to term. Uncertainty arises regarding the use of hyperbaric oxygen (HBO) as a treatment for the pregnant patient because of possible adverse effects on the fetus that could be induced by oxygen at high partial pressures. While the dangers of hyperoxia to the fetus have been demonstrated in animal models, careful review of animal studies and human clinical experience indicates that the short duration of hyperoxic exposure attained during HBO therapy for CO poisoning can be tolerated by the fetus in all stages of pregnancy and reduces the risk of death or deformity to the mother and fetus. A case is presented of acute CO poisoning during pregnancy that was successfully treated with HBO. Recommendations are suggested for the use of HBO during pregnancy.

    Despite the fact that fetal drug exposure is common, the disposition of drugs in the fetus is poorly understood. This study aimed to investigate fetal placental and non-placental disposition of rosiglitazone in the pregnant ewe. Steady state was reached after day 5 of fetal infusion, and were ∼1.8 fold higher than maternal concentrations (P<0.001). The AUC for fetal rosiglitazone concentration throughout the infusion was inversely correlated with placental and fetal weight. Metabolic activity of the fetal liver microsomes were ∼25 fold lower than maternal microsomes (P<0.001). The findings suggest that trans-placental transfer is the major route through which rosiglitazone is cleared from the fetal compartment, while non-placental hepatic elimination makes only a minor contribution. This supports a limited capacity of the fetus for eliminating this class of drugs, and highlights the potential for drug toxicity when administering pharmacotherapy to the mother/fetus in human pregnancy.

    Plasmodium vivax is the most widely distributed human parasite and the main cause of human malaria outside the African continent. However, the knowledge about the genetic variability of P. vivax is limited when compared to the information available for P. falciparum. We present the results of a study aimed at characterizing the genetic structure of P. vivax populations obtained from pregnant women from different malaria endemic settings. Between June 2008 and October 2011 nearly 2000 pregnant women were recruited during routine antenatal care at each site and followed up until delivery. A capillary blood sample from the study participants was collected for genotyping at different time points. Seven P. vivax microsatellite markers were used for genotypic characterization on a total of 229 P. vivax isolates obtained from Brazil, Colombia, India and Papua New Guinea. In each population, the number of alleles per locus, the expected heterozygosity and the levels of multilocus linkage disequilibrium were assessed. The extent of genetic differentiation among populations was also estimated. Six microsatellite loci on 137 P. falciparum isolates from three countries were screened for comparison. The mean value of expected heterozygosity per country ranged from 0.839 to 0.874 for P. vivax and from 0.578 to 0.758 for P. falciparum. P. vivax populations were more diverse than those of P. falciparum. In some of the studied countries, the diversity of P. vivax population was very high compared to the respective level of endemicity. The level of inter-population differentiation was moderate to high in all P. vivax and P. falciparum populations studied. PMID:27011010

    Antiphospholipid antibodies (APAs) are characterized as a heterogeneous population of autoantibodies directed against different target antigens, predominantly anionic phospholipids or phospholipid-containing structures. The presence of APAs has been strongly associated with a variety of clinical disorders including adverse pregnancy complications such as spontaneous abortions, pregnancy-induced hypertension, preeclampsia and intrauterine growth retardation. The purpose of this study was to compare the prevalence of anticardiolipin antibodies (ACAs), which are routinely examined, with APAs directed against phosphatidylserine (APS), phosphatidylinositol (API), phosphatidylethanolamine (APE) and phosphatidylcholine (APC) in the sera of pregnant women. We examined 410 serum samples of pregnant women hospitalized in the department for pathological pregnancies. They underwent prenatal biochemical screening of fetal congenital abnormalities in the first and the second trimester of gravidity. Anticardiolipin IgG and IgM were measured using commercial ELISA kits (ImmuLisa Anti-Cardiolipin Antibody), whereas APS, APE, API and APC were determined by our modified ELISA kit. Among 410 pregnant women we found 21 patients (5.1%) positive for ACA IgG (>20 GPL) and 30 patients (7.3%) positive for ACA IgM (>10 MPL). It was found that 7.8% of pregnant women had at least one high-titer APA IgG and 9.8% high-titer APA IgM. One third of ACA IgG or IgM positive sera contained polyspecific autoantibodies reactive to at least two various phospholipids. In the group of IgG ACA positive women, 28.6% patients were positive for APS, 28.6% were positive or moderately positive for API, 23.8% for APC and 19% for APE. In the group of IgM ACA positive women, 33.3% were also positive for APS, 26.7% for APE, 26.7% for API and 23.3% for APC were present. IgG and IgM ACA negative patients exhibited a significantly lower incidence of other APA than the group of ACA positive pregnant women. It still

    Objective Promoting breastfeeding is major maternal and child health goal in India. It is unclear whether mothers receive additional food needed to support healthy breastfeeding. Methods Using the latest National Family and Health Survey (2005–2006), we applied multilevel linear regression models to document correlates of nutrition for (n = 20,764) breastfeeding women. We then compared consumption of pulses, eggs, meat, fish, dairy, fruit, and vegetables across a sample of breastfeeding, non-breastfeeding/pregnant (NBP), and pregnant women (n = 3,409) matched within households and five-year age bands. We tested whether breastfeeding women had greater advantages in the 18 high-focus states of India's National Rural Health Mission (NRHM). Results Vegetarianism, caste, and religion were the strongest predictors of breastfeeding women's nutrition. Breastfeeding women had no nutritional advantage compared to NBP women, and were disadvantaged in their consumption of milk (b = −0.14) in low-focus states. Pregnant women were similarly disadvantaged in their consumption of milk in low-focus states (b = −0.32), but consumed vegetables more frequently (b = 0.12) than NBP women in high-focus states. Conclusions Breastfeeding women do not receive nutritional advantages compared to NBP women. Targeted effort is needed to assess and improve nutritional adequacy for breastfeeding Indian women.

    During pregnancy, glycine and serine become more important because they are the primary suppliers of methyl groups for the synthesis of fetal DNA, and more glycine is required for fetal collagen synthesis as pregnancy progresses. In an earlier study, we reported that glycine flux decreased by 39% from the first to the third trimester in pregnant adolescent girls. As serine is a primary precursor for glycine synthesis, the objective of this study was to measure and compare glycine and serine fluxes and inter-conversions in pregnant adolescent girls and adult women in the first and third trimesters. Measurements were made after an overnight fast by continuous intravenous infusions of 2H2-glycine and 15N-serine in eleven adolescent girls (17·4 (se 0·1) years of age) and in ten adult women (25·8 (se 0·5) years of age) for 4 h. Adolescent girls had significantly slower glycine flux and they made less glycine from serine in the third (P<0·05) than in the first trimester. Baby birth length was significantly shorter of adolescent girls (P=0·04) and was significantly associated with third trimester glycine flux. These findings suggest that the pregnant adolescent cannot maintain glycine flux in late pregnancy compared with early pregnancy because of decreased synthesis from serine. It is possible that the inability to maintain glycine synthesis makes her fetus vulnerable to impaired cartilage synthesis, and thus linear growth.

    Introduction There is a balance between the oxidative and the anti-oxidative forces in human body. Some studies document decreased level of anti-oxidant in pre-eclampsia while other studies showed normal level of anti-oxidant in pre-eclampsia and the evidence is equivocal. Aim The aim of the present study was to assess enzymatic anti-oxidant activities in pre-eclamptic women and compare it with normotensive pregnant women with period of gestation between 28 to 36 weeks. Materials and Methods A community-based cross-sectional survey was conducted (from November 2012-December 2013) at the Ballabgarh Health and Demographic Surveillance System (HDSS) site which was managed by Centre for Community Medicine, All India Institute of Medical Sciences, New Delhi, India. All registered pregnant women with period of gestation between 28 weeks – 36 weeks were eligible for inclusion in the study. All eligible pregnant women were contacted through home visit. A total of 217 pregnant women were enrolled out of which 209 blood samples were collected from pregnant women. About three ml of blood from antecubital vein was drawn without use of tourniquet, under aseptic conditions. It was later analysed for the serum anti-oxidative measures {Malanoaldehyde, Vitamin C, Ferric Reducing Ability of Plasma (FRAP) levels}. Data were entered on Epi-Info version 3.5.4. Data management and analysis was carried out in Stata 11. The means were compared using t-test and p-value stated. Categorical data was analysed using chi-square test. Logistic regression was used and adjusted p-value was stated. Results A total of 217 pregnant women were eligible for the study and all were enrolled. Out of the 217 blood samples collected, eight samples accidently got destroyed. A total of 28 out of remaining 209 pregnant women (13.4%) had pre-eclampsia. Mean age (SD) was 22.4 (2.3) years, mean height (SD) was 156.6 (6.9) cm, mean weight (SD) was 65.1 (9.7) kg in pre-eclampsia group. In pre-eclampsia group mean

    Prenatal maternal stress (PNMS) can impact a variety of outcomes in the offspring throughout childhood and persisting into adulthood as shown in human and animal studies. Many of the effects of PNMS on offspring outcomes likely reflect the effects of epigenetic changes, such as DNA methylation, to the fetal genome. However, no animal or human research can determine the extent to which the effects of PNMS on DNA methylation in human offspring is the result of the objective severity of the stressor to the pregnant mother, or her negative appraisal of the stressor or her resulting degree of negative stress. We examined the genome-wide DNA methylation profile in T cells from 34 adolescents whose mothers had rated the 1998 Québec ice storm's consequences as positive or negative (that is, cognitive appraisal). The methylation levels of 2872 CGs differed significantly between adolescents in the positive and negative maternal cognitive appraisal groups. These CGs are affiliated with 1564 different genes and with 408 different biological pathways, which are prominently featured in immune function. Importantly, there was a significant overlap in the differentially methylated CGs or genes and biological pathways that are associated with cognitive appraisal and those associated with objective PNMS as we reported previously. Our study suggests that pregnant women's cognitive appraisals of an independent stressor may have widespread effects on DNA methylation across the entire genome of their unborn children, detectable during adolescence. Therefore, cognitive appraisals could be an important predictor variable to explore in PNMS research. PMID:25710121

    For a multitude of eminently modifiable reasons, death rates for pregnant women and girls and their newborn infants in poorly resourced countries remain unacceptably high. The concomitant high morbidity rates compound the situation. The rights of these vulnerable individuals are incompletely protected by existing United Nations human rights conventions, which many countries have failed to implement. The authors propose a novel approach grounded on both human rights and robust evidence-based clinical guidelines to create a 'human rights convention specifically for pregnant women and girls and their newborn infants'. The approach targets the 'right to health' of these large, vulnerable and neglected populations. The proposed convention is designed so that it can be monitored, audited and evaluated objectively. It should also foster a sense of national ownership and accountability as it is designed to be relevant to local situations and to be incorporated into local clinical governance systems. It may be of particular value to those countries that are not yet on target to meet the Millennium Development Goals (MDGs), especially MDGs 4 and 5, which target child and maternal mortality, respectively. To foster a sense of international responsibility, two additional initiatives are integral to its philosophy: the promotion of twinning between well and poorly resourced regions and a raising of awareness of how some well-resourced countries can damage the health of mothers and babies, for example, through the recruitment of health workers trained by national governments and taken from the public health system.

    This study aimed to describe the production process of an educational booklet focusing on health promotion of pregnant women. The action research method was used in this process composed of the following steps: choice of the content based on the needs of pregnant women, creation of illustrations, content preparation based on scientific literature, validation of the material by experts and pregnant women. This work resulted in the final version of the booklet, which was entitled "Celebrating life: our commitment with the health promotion of pregnant women". Active participation of health professionals and pregnant women through dialogue and collective strategy permeated the process of development of the booklet. The opinions of pregnant women and experts who considered the booklet enriching and enlightening justify the use of it as an additional resource of educational activities carried out during the prenatal care.

    Changing immune parameters during pregnancy have previously been reported in humans and cattle, and have been suggested to contribute to increased susceptibility to infections. However, data regarding immune parameters during pregnancy in sows are rare. In this study, we investigated the peripartal immune status of sows using phenotypical (FACS analysis) as well as functional (proliferation assays, cytokine analysis) parameters of peripheral blood mononuclear cells (PBMCs) in pregnant sows. In previous studies, we reported a modulation of the immune system after feed supplementation of the probiotic Bacillus cereus var. toyoi in piglets [Schierack, P., Wieler, L.H., Taras, D., Herwig, V., Tachu, B., Hlinak, A., Schmidt, M.F., Scharek, L., 2007. Bacillus cereus var. toyoi enhanced systemic immune response in piglets. Vet. Immunol. Immunopathol. 118, 1-11]. Here, we extended these previous studies to include investigations of possible probiotic effects on the peripartal immune status of sows and their reproductivity. We show that immune parameters of sows change during pregnancy, the proliferative response of PBMCs to several bacterial antigens in control animals decreased from days 90 to 30 ante partum. Relative numbers (%) of CD3+CD8+, CD4+, cytotoxic T, CD14+ and CD21+ cells were reduced compared to non-pregnant sows. In contrast, the proliferative response of PBMCs of probiotic-treated sows increased during pregnancy. Bacterial antigens primarily stimulated the proliferation of naïve CD21+ cells and the relative CD21+ cell numbers were elevated in the probiotic group in the absence of effects on other immune cell populations. The clinical and microbial status of both control and probiotic sows was similar, excluding pre-existing health problems or infections as responsible for the immunological changes, and feed supplementation also had no significant effects on reproductivity. The results suggest that the probiotic B. cereus var. toyoi can alter the

    Background The purpose of this study was compare of daily iron supplementation in three time frames- daily, weekly and three time weekly supplementation in preventing anemia in healthy pregnant women. Method The present study was a prospective simply randomized clinical trial. During January 2006- January 2008, 150 healthy pregnant women without anemia, in their 16th week of pregnancy were randomly allocated into three equal groups. The first group (n = 50) received a 50 mg-ferrous sulfate tablet daily, second group (n = 50) received a 50 mg-ferrous sulfate tablet three times a week, and the third group (n = 50) received two 50 mg-ferrous sulfate tablets (100 mg) weekly, respectively for 12 consecutive weeks. Serum hemoglobin, ferritin, and iron were measured before and after the supplementation. Paired t and ANOVA tests were used as appropriated. Results There were no significant differences between the pre- and post-treatment hemoglobin levels with iron supplementation in the three group (P = 0.518, P = 0.276, respectively). The mean serum iron level before and after treatment with iron supplementation in the three groups was not statistically significant (P = 0.962, P = 0.970, respectively). Although the mean serum ferritin level before and after treatment with iron supplementation was statistically significant in the three groups, no significant differences were found comparing the three groups (P = 0.827, P = 0.635 respectively). Conclusions This results suggested, three times a week or weekly iron supplementation is as effective as daily supplementation for healthy pregnant women without anemia.

    Summary Background Data on imported malaria in pregnant women are scarce. Method A retrospective, descriptive study of pooled data on imported malaria in pregnancy was done, using data from 1977 to 2014 from 8 different collaborators in Europe, the United States and Japan. Most cases were from the period 1991–2014. National malaria reference centresas well as specialists on this topic were asked to search their archives for cases of imported malaria in pregnancy. A total of 632 cases were collated, providing information on Plasmodium species, region of acquisition, nationality, country of residence, reason for travel, age, gestational age, prophylactic measures and treatment used, as well as on complications and outcomes in mother and child. Results Datasets from some sources were incomplete. The predominant Plasmodium species was P. falciparum in 72% of cases. Among the 543 cases where information on the use of chemoprophylaxis was known, 471 (74.5%) did not use chemoprophylaxis or used incorrect or incomplete chemoprophylaxis. The main reason for travelling was “visiting friends and relatives” VFR (48.6%) and overall, most cases of malaria were imported from West Africa (85.9%). Severe anaemia was the most frequent complication in the mother. Data on offspring outcome was limited, but spontaneous abortion was a frequently reported foetal outcome (n = 14). A total of 50 different variants of malaria treatment regimens were reported. Conclusion Imported cases of malaria in pregnancy are mainly P. falciparum acquired in sub-Saharan Africa. Malaria prevention and treatment in pregnant travellers is a challenge for travel medicine due to few data on medication safety and maternal and foetal outcomes. International, collaborative efforts are needed to capture standardized data on imported malaria cases in pregnant women. PMID:26227740

    Background: Sugammadex has been shown to decrease the efficiency of progesterone-containing oral contraceptive drugs which possess a steroid structure. Aims: The aim of the present study was to evaluate the effects of sugammadex on progesterone levels in pregnant rats as well as on the physiological course of the pregnancy. Study Design: Animal experiment. Methods: This study was approved by the Selçuk University Ethical Committee for Experimental Animal Research. Pregnant Winster Albino rats (n=26) were divided into three groups and administered with various intravenous injections on the 7th day of pregnancy. The control group (Group K, n=6) received 1.5 mL serum physiologic, the sugammadex group (Group S, n=10) received 30 mg/kg sugammadex and the sugammadex + rocuronium group (Group SR, n=10) received 30 mg/kg sugammadex and 3.5 mg/kg rocuronium. Progesterone levels were measured and the offspring were monitored for morphologic status. Results: Mean progesterone levels were 94.16±15.54 ng/mL in Group K, 87.86±12.48 ng/mL in Group S, and 94.53±16.10 ng/mL in Group SR (p>0.05). No stillbirth or miscarriage was observed in the rats. The mean number of offspring was 6.8±1.47 in Group K, 6.5±1.35 in Group S, and 6.4±1.17 in Group SR. The offspring appeared macroscopically normal. Conclusion: Sugammadex does not appear to affect the progesterone levels in pregnant rats in the first trimester and the clinical course. Successful completion of pregnancy and the absence of stillbirth or miscarriage will guide future studies about the use of sugammadex, particularly in the first trimester of the pregnancy.

    Introduction Considering that empowering expectant mothers is an important issue to maintain a healthy pregnancy, this study was conducted to evaluate the predictors of empowerment among Iranian pregnant women. Methods This cross sectional study was conducted in Golestan, North of Iran in 2015. A total number of 161 pregnant women were selected through random cluster sampling from urban health centers, using PASS software. The socio-political, educational, and mental-financial predictors of empowerment were measured using a self-structured questionnaire during pregnancy and was analyzed by a linear regression model using SPSS version 16. Results The findings of linear regression showed that educational dimension of empowerment had the highest coefficient in the regression model, on total empowerment (βeta standardized coefficient [β]=0.696 with DW=1.830 and means error=0). The total empowerment score of pregnant women was controlled by individual factors such as the age of marriage (β-0.228), employment (β-0.210), and educational factors such as participation in prenatal education classes (β-0.246), and moral issues such as sense of spiritual support (β-0.217). Conclusion By recognizing and observing predictors of empowerment during pregnancy, health care providers can increase women’s power over their pregnancy. Educational predictors of empowerment were the most important factors to empower women during pregnancy. The objective of childbirth education classes, therefore, should shift from simply giving information to women, towards giving them appropriate knowledge in order to provide them with empowerment during pregnancy.

    The aim of this study was to investigate gestation duration and the physiologic characteristics of pregnant dogs bearing cloned fetuses, especially in the prepartum period. A retrospective study was performed to compare gestation duration in females pregnant with cloned (somatic cell nuclear transfer) fetuses (cloned group) with those bearing noncloned fetuses (control group), and effects of litter size, birth weight, and breed of somatic cell donors on gestation duration in the cloned group were evaluated. Clinical delivery onset signs associated with serum progesterone concentration and rectal temperature were also compared in both groups. The gestation duration calculated from day of ovulation was significantly longer in the cloned (62.8 ± 0.3 days) versus the control group (60.9 ± 0.5 days; P < 0.001). There was a negative correlation between litter size and gestation duration including both groups (r = -0.59; P < 0.01), but there were no differences between birth weights or breed of cell donors and gestation duration in the cloned group. Even though the basal rectal temperature in the prepartum period was not different between control and cloned groups (36.9 ± 0.1 °C and 37.2 ± 0.1 °C, respectively), serum progesterone concentration on delivery day was significantly higher in the cloned group (2.2 ± 0.4 ng/ml) compared with the control group (0.5 ± 0.1 ng/ml; P < 0.05). The longer gestation duration of pregnant dogs bearing cloned fetuses might be because of the smaller litter size in this group. Also, the weaker drop in serum progesterone levels in the prepartum period in cloned dog pregnancies indicates that the parturition signaling process might be altered resulting in longer gestation periods.

    We assessed attitudes of a multi-ethnic sample of pregnant women in regard to participation in five data collection procedures planned for use in the National Children's Study. A cross-sectional survey was conducted in nine prenatal clinics in Kent County, Michigan between April and October 2006. Women were approached in clinic waiting rooms at the time of their first prenatal visit and 311 (91.0%) participated. Women were asked about their willingness to participate, and the smallest amount of compensation required for participation in a 45-min in-person interview, a 15-min telephone interview, maternal and infant medical record abstraction, and an infant physical examination. Percentages for willingness to participate were highest for telephone interview (83%), followed by in-person interview (60%), infant examination (57%), and maternal (56%) and infant medical records (54%). About 34-48% of women reported that no compensation would be required for participation by data procedure. Some women reported unwillingness to participate in telephone (9%) or personal (17%) interview, record abstraction (34%) or infant examination (26%), even with compensation. Education greater than high school was associated with increased odds of refusal for infant physical examination, adjusted odds ratio 2.44 [95% confidence interval 1.41, 4.23]. In conclusion, 9-34% of pregnant women, depending on procedure, stated they would not participate in non-invasive research procedures such as medical record abstraction and infant examination, even with compensation. Resistance to these research procedures was especially noted among more highly educated women. Planning for the National Children's Study will have to address potential resistance to research among pregnant women.

    Rural residence and maternal stress are risk factors for adverse maternal-child health outcomes across the globe, but rural women have been largely overlooked in maternal stress research. We recruited low-income, rural pregnant women for qualitative interviews to explore their stress exposures during pregnancy, reactions to stress, and priorities for stress reduction. We also used quantitative measures (Perceived Stress Scale, Center for Epidemiologic Studies of Depression Scale-Revised, Posttraumatic Stress Disorder Checklist-Civilian, Lifetime Exposure to Violence Scale) to describe stress exposures and reactions. We interviewed 24 pregnant rural women from a Midwestern US state, who were primarily young, white, partnered, and unemployed. Women's predominant stressor was financial stress, compounded by a lack of employment, transportation, and affordable housing options; extended family interdependence; small-town gossip; isolation/loneliness; and boredom. Quantitative measures revealed high levels of global perceived stress, violence exposure, and symptoms of depression and posttraumatic stress disorder among the sample. Women most commonly reported that employment and interventions to increase their employability would most effectively decrease their stress, but faced numerous barriers to education or job training. Tested maternal stress interventions to date include nurse-case management, teaching women stress management techniques, and mind-body interventions. Pregnant women's own priorities for stress-reduction intervention may differ, depending on the population under study. Our findings suggest that rural clinicians should address maternal stress, violence exposure, and mental health symptoms in prenatal care visits and that clinicians and researchers should include the voices of rural women in the conceptualization, design, implementation, and evaluation of maternal stress-reduction interventions.

    Gitelman syndrome is characterized by hypokalemia, metabolic alkalosis, hypocalciuria, and hypomagnesemia. The clinical course of Gitelman syndrome in pregnant women remains unclear, but it is thought to be benign. We report here the first Korean case of atypical eclampsia in a 31-year-old who was diagnosed with Gitelman syndrome incidentally during an antenatal screening test. The patient did well during pregnancy despite significant hypokalemia. At 33 weeks’ gestation, the patient exhibited eclampsia, hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome, and renal insufficiency without significant hypertension or proteinuria. We explain this unusual clinical course through a review of the relevant literature. PMID:28393002

    2000-08-01

    The objective of this study was to test the hypothesis that a decrease in renal interstitial hydrostatic pressure (RIHP) accounts for the blunted pressure natriuresis during pregnancy. RIHP was measured in nonpregnant (NP; n = 9), midterm pregnant (MP; 12-14 days after conception; n = 10), and late-term pregnant (LP; 18-21 days after conception; n = 12) female Sprague-Dawley rats at two renal perfusion pressure (RPP) levels (99 and 120 mmHg). At the lower RPP level, RIHP was 5.9 +/- 0.3 mmHg for NP, 3.4 +/- 0.4 mmHg for MP (P < 0.05 vs. NP), and 2.9 +/- 0.1 mmHg for LP (P < 0.05 vs. NP) rats. The increase in RPP from 99 to 120 mmHg resulted in pressure natriuretic and diuretic responses in all groups; however, the increases in fractional excretion of sodium (DeltaFE(Na)), urine flow rate (DeltaV), and DeltaRIHP were significantly greater (P < 0. 05) in NP compared with both MP and LP rats. DeltaFE(Na), DeltaV, and DeltaRIHP were 2.06 +/- 0.28%, 81.44 +/- 14.10 microl/min, and 3. 0 +/- 0.5 mmHg for NP; 0.67 +/- 0.13%, 28.03 +/- 5.28 microl/min, and 0.5 +/- 0.2 mmHg for MP; and 0.48 +/- 0.12%, 18.14 +/- 4.70 microl/min, and 0.4 +/- 0.1 mmHg for LP rats. In conclusion, RIHP is significantly lower in pregnant compared with nonpregnant rats at similar RPP levels. Also, the ability of pregnant rats to increase RIHP in response to an increase in RPP is blunted. These changes in RIHP may play an important role in the blunted pressure natriuresis and contribute to the conservation of sodium and water that is critical for fetal growth and development during normal pregnancy.

    Neuroendocrine tumours (NET) are a heterogeneous group of neoplasms commonly occurring in the gastrointestinal tract or lungs but can occur in other regions. Primary ovarian NET account for 5% of all NET and 0.1% of all ovarian malignancies. In metastatic disease, the therapeutic goal is to extend survival and to improve quality of life. As these tumours express somatostatin receptors, somatostatin analogues are frequently used to control symptoms. Here we present a case of a pregnant woman with an ovarian NET with liver metastases and carcinoid syndrome who was treated with the somatostatin analogue, Octreotide LAR. We also summarize reported data of the use of somatostatin analogues during pregnancy. PMID:22331988

    Key points Older pregnant women have a greater risk of operative delivery, still birth and post‐term induction.This suggests that maternal age can influence the timing of birth and processes of parturition.We have found that increasing maternal age in C57BL/6J mice is associated with prolongation of gestation and length of labour.Older pregnant mice also had delayed progesterone withdrawal and impaired myometrial function.Uterine ageing and labour dysfunction should be investigated further in older primigravid women. Abstract Advanced maternal age (≥35 years) is associated with increased rates of operative delivery, stillbirth and post‐term labour induction. The physiological causes remain uncertain, although impaired myometrial function has been implicated. To investigate the hypothesis that maternal age directly influences successful parturition, we assessed the timing of birth and fetal outcome in pregnant C57BL/6J mice at 3 months (young) and 5 months (intermediate) vs. 8 months (older) of age using infrared video recording. Serum progesterone profiles, myometrium and cervix function, and mitochondrial electron transport chain complex enzymatic activities were also examined. Older pregnant mice had a longer mean gestation and labour duration (P < 0.001), as well as reduced litter size (P < 0.01) vs. 3‐month‐old mice. Older mice did not exhibit the same decline in serum progesterone concentrations as younger mice. Cervical tissues from older mice were more distensible than younger mice (P < 0.05). Oxytocin receptor and connexin‐43 mRNA expression were reduced in the myometrium from 8‐month‐old vs. 3‐month‐old mice (P < 0.05 and P < 0.01 respectively) in tandem with more frequent but shorter duration spontaneous myometrial contractions (P < 0.05) and an attenuated contractile response to oxytocin. Myometrial mitochondrial copy number was reduced in older mice, although there were no age‐induced changes to the enzymatic

    Cerebral venous thrombosis (CVT) is a relatively rare but serious condition potentially reversible upon accurate diagnosis and adequate therapy. The peri-partum state and pregnancy are predisposing factors and TVC accounts for about 6% of maternal deaths. Its clinical symptoms depend on the the thrombus site and extension, and also on the existing collateral vessels network. We present the case of a 33 year-old woman, 13 weeks pregnant, that complained of headaches and whose cranial magnetic resonance imaging revealed a subtotal oclusión of the superior sagittal sinus. We discuss the imaging features of dural venous thrombosis in the acute phase.

    Background Racial or ethnic and economic disparities exist in terms of oral diseases among pregnant women and children. The authors hypothesized that women of a racial or ethnic minority have less oral health knowledge than do women not of a racial or ethnic minority. Therefore, the authors conducted a study to assess and compare maternal oral health knowledge and beliefs and to determine if maternal race and ethnicity or other maternal factors contributed to women’s knowledge or beliefs. Methods The authors administered a written oral health questionnaire to pregnant women. The authors calculated the participants’ knowledge and belief scores on the basis of correct answers or answers supporting positive oral health behaviors. They conducted multivariable analysis of variance to assess associations between oral health knowledge and belief scores and characteristics. Results The authors enrolled 615 women in the study, and 599 (97.4 percent) completed the questionnaire. Of 599 participants, 573 (95.7 percent) knew that sugar intake is associated with caries. Almost one-half (295 participants [49.2 percent]) did not know that caries and periodontal disease are oral infections. Median (interquartile range) knowledge and belief scores were 6.0 (5.5–7.0) and 6.0 (5.0–7.0), respectively. Hispanic women had median (interquartile range) knowledge and belief scores significantly lower than those of white or African American women (6.0 [4.0–7.0] versus 7.0 [6.0–7.0] versus 7.0 [6.0–7.0], respectively [P < .001]; and 5.0 [4.0–6.0] versus 6.0 [5.0–7.0] versus 6.0 [5.0–7.0], respectively [P < .001]). Multivariable analysis of variance results showed that being of His-panic ethnicity was associated significantly with a lower knowledge score, and that an education level of eighth grade or less was associated significantly with a lower belief score.

    The aim of this study was to investigate the experience of birth planning for pregnant women. Research in Australia and overseas has suggested that there are a number of conflicting issues with women's preparation and participation in childbirth. The researcher interviewed forty-two first time mothers in a variety of maternity settings around Victoria to ascertain the importance of birth planning in their approach to childbirth and the ways they went about making their plan and negotiating their needs with health professionals. The data from those interviews demonstrated that the means women used to negotiate their needs for childbirth with health professionals had little influence on their overall pregnancy and birth experience.

    A survey of postpartum women in Brisbane revealed that many gave up smoking just before or shortly after becoming pregnant, and that many of the remainder reduced their rate of consumption. Husbands who smoked showed no comparable changes in behaviour. Thus apparently many couples were aware of the dangers to the fetus of active smoking by the woman, but not of the dangers of her passive inhalation of smoke. Other significant findings included (i) increasing rates of consumption during successive pregnancies, (ii) high degrees of conformity for most habits (e.g. use of filters), and (iii) stronger addiction and earlier starting ages among heavy smokers than light smokers.

    Summary Background: Nitrous oxide can cause disordered blood cell proliferation and lead to pancytopenia and altered immune function. Case Report: A young pregnant female patient presented after binge nitrous oxide abuse with altered mental status and abnormal vital signs. From her initial assessment she was noted to have pancytopenia and was found to have megaloblastic, hyper-cellular changes in a subsequent bone marrow biopsy. This presentation was determined to be secondary to toxic effects after heavy use of nitrous oxide. Conclusions: Nitrous oxide exposure, including use as an inhalant, over 12 hours can lead to bone marrow abnormalities such as megaloblastic hematopoiesis. PMID:23569553

    This article provides a summary of currently available information from a broad range of disciplines aimed at guiding the physician caring for the pregnant patient who requires nonobstetric surgery. An understanding of the anatomic and physiologic alterations that occur during pregnancy will allow such procedures to be accomplished with morbidity and mortality approaching those of nonpregnant surgical patients. The presence of the fetus does impose some restraint; however, this should rarely impair appropriate diagnosis and treatment of maternal disease. This obtains from the broad range of diagnostic and therapeutic alternatives available, and from the fact that what is beneficial for maternal health is generally best for the fetus. 64 references.

    The foodborne pathogen Listeria monocytogenes can cause infection in immunocompromised humans and in the fetuses of pregnant women. We have demonstrated that one group of genetically similar L. monocytogenes strains (random amplified polymorphic DNA [RAPD] type 9) dominate and persist in several independent fish processing plants. The purpose of the present study was to determine the virulence potential of one RAPD type 9 strain (La111), one human clinical strain (Scott A), and one monkey clinical strain (12443) in a pregnant guinea pig model. Animals were orally exposed to 10(8) CFU of L. monocytogenes in whipping cream on gestation day (GD) 36 and euthanized on GD 42, 45, or 56. Strains 12443 and Scott A were shed from treated animals for 20 days, whereas La111 was shed only in the first 10 days. Strains 12443 and Scott A were recovered from maternal liver, spleen, and gallbladder on all 3 days of euthanization, whereas La111 was recovered only at GD 45 and 56. Scott A was not isolated from any placentas or fetuses. For dams treated with 12443, 22% of the fetuses were positive for L. monocytogenes, and surprisingly, treatment of dams with La111 resulted in 56% infected fetuses. L. monocytogenes was isolated from 16 and 20% of placentas for 12443 and La111, respectively. The study demonstrates that a food processing plant persistent strain of L. monocytogenes is able to cross the fetoplacental barrier in pregnant guinea pigs. Furthermore, we demonstrate that although information can be gained from model virulence assays, assessment of the virulence potential of a strain may require more complex hosts.

    A total of 5,366 pregnant Turkish women were screened for hepatitis B surface antigen (HBsAg) and 225 (4.2%) of them were found to be positive. Hepatitis B e antigen (HBeAg) was detected in 6.2% of HBsAg-positive pregnant women. the overall prevalence of HBsAg and antibody to HBsAg (anti-HBs) among the spouses, previous children, mothers and first degree relatives of the HBsAg-positive pregnant women was 56%, 49%, 79% and 74% respectively. The prevalence of HBsAg is thus high in pregnant Turkish women with familial clustering of hepatitis B virus infection.

    The study was to determine the seroprevalence of toxoplasmosis in the sera of pregnant women in central Taiwan and to investigate the levels of cytokine in the sera of pregnant women with Toxoplasma gondii infection. The 220 blood samples were collected from pregnant women. The haematological parameters of peripheral blood were analysed by a haematology analyser. Serum samples of the pregnant women were analysed by a commercially available anti-T. gondii IgM/IgG antibody enzyme-linked immunosorbent assay (ELISA) kit and FlowCytomix assays. Six (2.7%) of the sera samples had IgM anti-T. gondii antibodies, and twenty (9.1%) had T. gondii IgG seropositive. All six IgM seropositive samples had low IgG avidity, indicative of acute infection. Total white blood cells and eosinophils were statistically significantly increased (p<0.05) in pregnant women with T. gondii infection, as compared with healthy pregnant women. Th1 cytokines IFN-γ, IL-1β, IL-2 and IL-12 p70, and Th2 cytokines IL-10 in pregnant women with T. gondii IgM/IgG seropositive were significantly increased (p<0.05), as compared with healthy pregnant women. These results showed that both of Th1 and Th2 cytokines play an important role in the toxoplasmosis of pregnant women.

    The purpose of this study was to investigate the antibodies to Toxoplasma gondii in human immunodeficiency virus (HIV)-infected pregnant women and to determine the association between serological profile and the risk of congenital toxoplasmosis. The study, conducted in a public maternity ward from May 2002 to April 2005, included all HIV-infected women who delivered live infants during the 36 months, and, as a control group, all HIV-negative women that delivered live infants in the first 12 months of the study. Antibodies to T. gondii were detected in 1,624 of 2,421 HIV-negative women (67%; 95% confidence interval [CI] 65-69%) and in 121 of 168 HIV-infected patients (72%; 95% CI 65-79%). A total of 547 HIV-negative and 103 HIV-infected patients were tested at delivery and had positive T. gondii-specific IgG. In HIV-negative women, the median of the specific IgG concentration was 79 (interquartile range 38-160), and in HIV-infected patients, it was 283 (interquartile range 94-704) (P < 0.001). In the group of co-infected women, the only infant with congenital toxoplasmosis was born to a mother with acute toxoplasmosis infection acquired during pregnancy who did not have a high specific IgG concentration or a positive result for specific IgM. We concluded that high T. gondii-specific IgG values were much more frequent among HIV-infected pregnant women, but it did not translate into an increased risk of maternal-fetal transmission of toxoplasmosis.

    Although the potential risk of silver nanoparticles (AgNPs) to humans has recently increased due to widespread application, the potential effects of AgNPs on embryo-fetal development have not yet been determined. This study investigated the potential effects of AgNPs on pregnant dams and embryo-fetal development after maternal exposure on gestational days (GD) 6-19 in rats. AgNPs were administered to pregnant rats by gavage at concentrations of 0, 100, 300, and 1000 mg/kg/day. All dams were subjected to Cesarean section on GD 20 and the fetuses were examined for signs of embryotoxic and teratogenic effects. Examinations of hepatic oxidant/antioxidant balance and serum biochemistry were also added to the routine developmental toxicity study. Treatment with AgNPs caused a decrease in catalase and glutathione reductase activities at ≥100 mg/kg/day and a reduction in glutathione content at 1000 mg/kg/day in maternal liver tissues. However, no treatment-related deaths or clinical signs were observed in any of the animals treated with AgNPs. No treatment-related differences in maternal body weight, food consumption, gross findings, serum biochemistry, organ weight, gestation index, fetal deaths, fetal and placental weights, sex ratio, or morphological alterations were observed between the groups. The results show that repeated oral doses of AgNPs during pregnancy caused oxidative stress in hepatic tissues at ≥100 mg/kg/day, but did not cause developmental toxicity at doses of up to 1000 mg/kg/day. The no-observed-adverse-effect level of AgNPs is considered to be <100 mg/kg/day for dams and 1000 mg/kg/day for embryo-fetal development.

    Fetal alcohol spectrum disorders (FASD) are difficult to diagnose since many heavily exposed infants, at risk for intellectual disability, do not exhibit craniofacial dysmorphology or growth deficits. Consequently, there is a need for biomarkers that predict disability. In both animal models and human studies, alcohol exposure during pregnancy resulted in significant alterations in circulating microRNAs (miRNAs) in maternal blood. In the current study, we asked if changes in plasma miRNAs in alcohol-exposed pregnant mothers, either alone or in conjunction with other clinical variables, could predict infant outcomes. Sixty-eight pregnant women at two perinatal care clinics in western Ukraine were recruited into the study. Detailed health and alcohol consumption histories, and 2nd and 3rd trimester blood samples were obtained. Birth cohort infants were assessed by a geneticist and classified as unexposed (UE), heavily prenatally exposed and affected (HEa) or heavily exposed but apparently unaffected (HEua). MiRNAs were assessed in plasma samples using qRT-PCR arrays. ANOVA models identified 11 miRNAs that were all significantly elevated in maternal plasma from the HEa group relative to HEua and UE groups. In a random forest analysis classification model, a combination of high variance miRNAs, smoking history and socioeconomic status classified membership in HEa and UE groups, with a misclassification rate of 13%. The RFA model also classified 17% of the HEua group as UE-like, whereas 83% were HEa-like, at least at one stage of pregnancy. Collectively our data indicate that maternal plasma miRNAs predict infant outcomes, and may be useful to classify difficult-to-diagnose FASD subpopulations. PMID:27828986

    Triclosan (TCS) is a broad-spectrum antimicrobial agent that is frequently used in pharmaceuticals and personal care products. Reports have shown that TCS is a potential endocrine disruptor; however, the potential effects of TCS on placental endocrine function are unclear. The aim of this study was to investigate the endocrine disrupting effects of TCS on the placenta in pregnant rats. Pregnant rats from gestational day (GD) 6 to GD 20 were treated with 0, 30, 100, 300 and 600 mg/kg/d TCS followed by analysis of various biochemical parameters. Of the seven tissues examined, the greatest bioaccumulation of TCS was observed in the placenta. Reduction of gravid uterine weight and the occurrence of abortion were observed in the 600 mg/kg/d TCS-exposed group. Moreover, hormone detection demonstrated that the serum levels of progesterone (P), estradiol (E2), testosterone (T), human chorionic gonadotropin (hCG) and prolactin (PRL) were decreased in groups exposed to higher doses of TCS. Real-time quantitative reverse transcriptase-polymerase chain reaction (Q-RT-PCR) analysis revealed a significant increase in mRNA levels for placental steroid metabolism enzymes, including UDP-glucuronosyltransferase 1A1 (UGT1A1), estrogen sulfotransferase 1E1 (SULT1E1), steroid 5α-reductase 1 (SRD5A1) and steroid 5α-reductase 2 (SRD5A2). Furthermore, the transcriptional expression levels of progesterone receptor (PR), estrogen receptor (ERα) and androgen receptor (AR) were up-regulated. Taken together, these data demonstrated that the placenta was a target tissue of TCS and that TCS induced inhibition of circulating steroid hormone production might be related to the altered expression of hormone metabolism enzyme genes in the placenta. This hormone disruption might subsequently affect fetal development and growth. PMID:27149376

    Globally, human exposures to organophosphate (OP) insecticides may pose a significant burden to the health of mothers and their developing fetuses. Unfortunately, relevant data is limited in certain areas of the world concerning sources of exposure to OP insecticides in pregnant populations. To begin to address this gap in information for Puerto Rico, we studied repeated measures of urinary concentrations of 10 OP insecticide metabolites among 54 pregnant women from the northern karst region of the island. We also collected demographic data and self-reported information on the consumption of fruits, vegetables, and legumes in the past 48-hr before urine collection and home pest-related issues. We calculated the distributions of the urinary biomarkers and compared them to women of reproductive age from the general U.S. population. We also used statistical models accounting for correlated data to assess within-subject temporal variability of the urinary biomarkers and to identify predictors of exposure. We found that for all but two metabolites (para-nitrophenol [PNP], diethylthiophosphate [DETP]), 50th or 95th percentile urinary concentrations (the metric that was used for comparison was based on the biomarker’s detection frequency) of the other eight metabolites (3,5,6-trichloro-2-pyridinol [TCPY], 2-isopropyl-4-methyl-6-hydroxy-pyrimidine, malathion dicarboxylic acid, diethylphosphate, diethyldithiophosphate, dimethylphosphate, dimethylthiophosphate [DMTP], dimethyldithiophosphate) were somewhat lower in our cohort compared with similarly aged women from the continental United States. TCPY, PNP, DETP, and DMTP, which were the only urinary metabolites detected in greater than 50% of the samples, had poor reproducibility (intraclass correlation coefficient range: 0.19–0.28) during pregnancy. Positive predictors of OP insecticide exposure included: age; marital or employment status; consumption of cherries, grape juice, peanuts, peanut butter, or raisins; and

    Pregnancy represents a risk factor in the occurrence of vaginal candidosis. The objectives of our study were: to make determination of the microscopic findings of vaginal swab, frequency of Candida species in the culture of pregnant women and patients who are not pregnant, determine the Candida species in all cultures, and to determine the frequency and differences in the frequency of C. albicans and other non-albicans species. In one year study performed during 2006 year, we tested patients of Gynaecology and Obstetrics clinic of the Clinical Centre in Sarajevo and Gynaecology department of the General hospital in Sarajevo. 447 woman included in the study were separated in two groups: 203 pregnant (in the last trimester of pregnancy), and 244 non-pregnant woman in period of fertility. Each vaginal swab was examined microscopically. The yeast, number of colonies, and the species of Candida were determined on Sabouraud dextrose agar with presence of antibiotics. For determination of Candida species, we used germ tube test for detection of C. albicans, and cultivation on the selective medium and assimilation tests for detection of non-albicans species. The results indicated positive microscopic findings in the test group (40,9%), as well as greater number of positive cultures (46,8%). The most commonly detected species for both groups was C. albicans ( test group 40.9% and control group 23,0%). The most commonly detected non-albicans species for the test group were C. glabrata (4,2 %) and C. krusei (3,2%), and for the control group were C. glabrata (3,2%) and C. parapsilosis (3,2%). The microscopic findings correlated with the number of colonies in positive cultures. In the test group, we found an increased number of yeasts (64,3%), and the pseudopyphae and blastopores by microscopic examination as an indication of infection. In the control group, we found a small number of yeasts (64,6%) , in the form of blastopores, as an indication of the candida colonisation. Our

    Preeclampsia is one of the most common and severe pregnancy complications, which ethiology remains unclear. It is certain that endothelial dysfunction plays a key role in the development of preeclampsia. Homocysteine is an important independent cardiovascular risk factor, which might induce the endothelial dysfunction observed in preeclampsia. 26 pregnant women--14 with preeclampsia (group 1) and 12 healthy term pregnant controls (group 2) were enrolled in the study between December 2003 and August 2004. Six of the women in this group had a superimposed preeclampsia. The mean homocysteine level in the first group was 11,04 mol/l, while in the control group it was 6,24 micromol/l (p < 0.05). The women with a severe preeclampsia had a significantly higher serum homocysteine levels than those with mild form (F = 0.025). Seven of the patients (50%) gave birth before 34th weeks of gestation. The study finds a link between the serum homocysteine as an endothelial dysfunction marker and the development of preeclampsia and a relation between the severity of preeclampsia and the degree of the elevation of the serum homocysteine levels.

    The iatrogenic risk of HIV vertical transmission, calculated in initial epidemiologic studies, seemed to counterindicate invasive prenatal diagnosis (PND) procedures. The implementation of highly active antiretroviral therapy (HAART) represented a turning point in PND management, owing to a rapid and effective reduction of maternal viral load (VL). In the present study, we identified cases of vertical transmission in HIV-infected pregnant women who did amniocentesis in the second trimester of pregnancy (n = 27), from 1996 to 2011. We divided our sample into Group A--women under HAART when submitted to amniocentesis (n = 20) and Group B--women without antiretroviral therapy before amniocentesis (n = 7). We had 1 case of vertical transmission in Group B. Preconceptional or early first trimester HIV serology is essential to avoid performing an amniocentesis without antiretroviral therapy or viral suppression. When there is an indication for amniocentesis in an HIV-infected pregnant woman, it should be done if the patient is on HAART and, if possible, when VL is undetectable. Nowadays, with combined first trimester screening test to select pregnancies with high risk of aneuploidies, advanced maternal age is a less frequent indication to perform PND invasive procedures, representing an outstanding gain in prenatal diagnosis of this population.

  1. Effects of ethanol on pregnant rats and their offspring.

    Pregnant rats were intubated with either 1.0 or 2.0 g/kg of ethanol daily throughout gestation. Pair-fed vehicle-treated, and nontreated rats fed ad libitum, served as control groups for ethanol-treated animals. Ethanol treatment reduced food and water consumption and attenuated the gain in body weight of pregnant animals relative to nontreated animals fed ad libitum. Litter size, litter weight, and the mean weight per pup were reduced in both the ethanol-treated and pair-fed control groups. There was no evidence of gross malformations in any of the off-spring. Since the reduction in litter size and litter weights did not differ significantly between ethanol-treated and pair-fed controls, the effects of treatment with ethanol appeared to be related to a reduction in maternal intake of calories rather than to the direct effect of ethanol on the developing fetus. There were no significant differences between any of the groups of offspring on one-way shock avoidance learning, water maze escape learning, spontaneous alternation, or brightness discrimination learning in tests beginning at 75 days of age. Thus, at the doses of alcohol used in this study, there was no evidence of behavioral teratogenesis comparable to that reported for higher doses in animals or in man characterized by the fetal alcohol syndrome.

    OBJECTIVE: The main objective of this study was to investigate the risk factors associated with periodontitis in pregnant women. METHODS: This study was conducted in two stages. In Stage 1, a cross-sectional study was conducted to determine the prevalence of periodontitis among 810 women treated at the maternity ward of a university hospital. In Stage 2, the factors associated with periodontitis were investigated in two groups of pregnant women: 90 with periodontitis and 720 without. A hierarchized approach to the evaluation of the risk factors was used in the analysis, and the independent variables related to periodontitis were grouped into two levels: 1) socio-demographic variables; 2a) variables related to nutritional status, smoking, and number of pregnancies; and 2b) variables related to oral hygiene. Periodontitis was defined as a probing depth ≥4 mm and an attachment loss ≥3 mm at the same site in four or more teeth. A logistic regression analysis was also performed. RESULTS: The prevalence of periodontitis in this sample was 11%. The variables that remained in the final multivariate model with the hierarchized approach were schooling, family income, smoking, body mass index, and bacterial plaque. CONCLUSION: The factors identified underscore the social nature of the disease, as periodontitis was associated with socioeconomic, demographic status, and poor oral hygiene. PMID:22249477

    Introduction Primary signet-ring cell carcinoma (SRCC) of the colon and rectum are rare form, which present at an advanced stage and have poor prognosis. Different treatment policies of SRCC during different gestational age of pregnancy are explored from the literature. Case study A 26-year-old young pregnant female with 10-week gestation presented with constipation and blood in stools and on per rectal examination a tender circumferential stricture was present 2 cm above the anal verge. Magnetic resonant imaging (MRI) pelvis of the patient revealed rectal thickening, the biopsy of which revealed characteristic appearance of “linitis plastica” and diagnosed as poorly differentiated adenocarcinoma with signet ring morphology with wide spread positivity for cytokeratin & p53. With this diagnosis, patient underwent medical termination of pregnancy (MTP). Discussion SRCC of the colon comprises about only 1% of all cases of colon cancer. When compared with other types of adenocarcinoma, patients with SRCC in the colon are younger and more likely to experience lymph node metastasis. Its incidence in pregnancy is estimated to be less than 0.1%. Certainly, any pregnant patient who reports rectal bleeding or has hemoccult positive stool on examination deserves careful evaluation to rule out cancer. The complex treatment of colorectal cancer in pregnancy is based on the gestational age of the fetus, tumor stage and need for emergent vs. elective management. PMID:25830043

    The objective was to examine uterine artery hemodynamics and maternal serum profiles in pregnant heifers supplemented with dietary melatonin (MEL) or no supplementation (CON). In addition, melatonin receptor-mediated responses in steroid metabolism were examined using a bovine endometrial epithelial culture system. Twenty singleton pregnant Holstein heifers were supplemented with 20 mg of melatonin (n = 10) or no melatonin supplementation (control; n = 10) from days 190 to 262 of gestation. Maternal measurements were recorded on days 180 (baseline), 210, 240, and 262 of gestation. Total uterine blood flow was increased by 25% in the MEL-treated heifers compared with the CON. Concentrations of progesterone were decreased in MEL vs CON heifers. Total serum antioxidant capacity was increased by 43% in MEL-treated heifers when compared with CON. Activity of cytochrome P450 1A, 2C, and superoxide dismutase was increased in bovine endometrial epithelial cells treated with melatonin, whereas the melatonin receptor antagonist, luzindole, negated the increase in cytochrome P450 2C activity. Moreover, estradiol or progesterone treatment altered bovine uterine melatonin receptor expression, which could potentiate the melatonin-mediated responses during late gestation. The observed increase in total uterine blood flow during melatonin supplementation could be related to its antioxidant properties. Compromised pregnancies are typically accompanied by increased oxidative stress; therefore, melatonin could serve as a therapeutic supplementation strategy. This could lead to further fetal programming implications in conjunction with offspring growth and development postnatally.

    Cyanide is a ubiquitous chemical in the environment and has been associated with many intoxication episodes; however, little is known about its potentially toxic effects on development. The aim of this study was to evaluate the effects of maternal exposure to potassium cyanide (KCN) during pregnancy on both sows and their offspring. Twenty-four pregnant sows were allocated into four groups that orally received different doses of KCN (0.0, 2.0, 4.0, and 6.0 mg/kg of body weight) from day 21 of pregnancy to term. The KCN-treated sows showed histological lesions in the CNS, thyroid follicle enlargement, thyroid epithelial thickening, colloid reabsorption changes, and vacuolar degeneration of the renal tubular epithelium. Sows treated with 4.0 mg/kg KCN showed an increase in the number of dead piglets at birth. Weaned piglets from all KCN-treated groups showed histological lesions in the thyroid glands with features similar to those found in their mothers. The exposure of pregnant sows to cyanide thus caused toxic effects in both mothers and piglets. We suggest that swine can serve as a useful animal model to assess the neurological, goitrogenic, and reproductive effects of cyanide toxicosis.

    Vitamin D is linked to a number of adverse pregnancy outcomes through largely unknown mechanisms. This study was conducted to examine the role of vitamin D status in metabolomic profiles in a group of 30 pregnant, African American adolescents (17.1 ± 1.1 years) at midgestation (26.8 ± 2.8 weeks), in 15 adolescents with 25-hydroxy vitamin D (25(OH)D) ≥20 ng/mL, and in 15 teens with 25(OH)D <20 ng/mL. Serum metabolomic profiles were examined using gas chromatography–mass spectrometry and liquid chromatography–tandem mass spectrometry. A novel hierarchical mixture model was used to evaluate differences in metabolite profiles between low and high groups. A total of 326 compounds were identified and included in subsequent statistical analyses. Eleven metabolites had significantly different means between the 2 vitamin D groups, after correcting for multiple hypothesis testing: pyridoxate, bilirubin, xylose, and cholate were higher, and leukotrienes, 1,2-propanediol, azelate, undecanedioate, sebacate, inflammation associated complement component 3 peptide (HWESASXX), and piperine were lower in serum from adolescents with 25(OH)D ≥20 ng/mL. Lower maternal vitamin D status at midgestation impacted serum metabolic profiles in pregnant adolescents. PMID:25367051

    A low chronologic age (less than or equal to 15 years) and low gynecologic age (less than or equal to 2 years) have been considered factors that increase medical complications among adolescent pregnant women. Gynecologic age (GA) is defined in this study as age in years at conception minus age at menarche. Two hundred twelve consecutive pregnant teenagers were followed prospectively in the Teen OB Clinic at the University of California, San Diego Medical Center, between August 1978 and July 1981. The clinic population consisted of 37.3 percent Whites, 35.8 percent Hispanics, 20.8 percent Blacks, and 6.1 percent other (mostly Indochinese). Sixty-eight percent of the patients were funded by MediCal. The patient population was divided by chronological age (CA) at conception into those 15 years or less or 16 years or older. A low chronological age was found to be a significant risk factor for premature rupture of membranes. Teenagers with a low gynecologic age (less than or equal to 2) had a lower mean pre-pregnancy weight and body mass index (Kg/M2) than teenagers with a higher gynecologic age. In this study, we did not find that a low CA or GA was correlated with a higher frequency of pregnancy-induced hypertension, prenatal medical problems, obstetrical problems at labor or delivery, or an excessive number of low-birthweight infants.

    With the greater frequency of renal transplant surgery, more female pts are becoming pregnant and carrying to term. In the renal allograft blood vessels and ureter may be compressed resulting in impaired renal function and/or, hypertension. Toxemia of pregnancy is seen more frequently than normal. Radionuclide renal scan monitoring may be of significant value in this high risk obstetrical pt. After being maintained during the pregnancy, renal function may also deteriorate in the post partum period. 5 pregnant renal transplant pts who delivered live babies had renal studies with Tc-99m DTPA to assess allograft perfusion and function. No transplanted kidney was lost during or after pregnancy as a result of pregnancy. No congenital anomalies were associated with transplant management. 7 studies were performed on these 5 pts. The 7 scans all showed the uterus/placenta. The bladder was always distorted. The transplanted kidney was rotated to a more vertical position in 3 pts. The radiation dose to the fetus is calculated at 0.024 rad/mCi administered. This study demonstrates the anatomic and physiologic alterations expected in the transplanted kidney during pregnancy when evaluated by renal scan and that the radiation burden may be acceptable in management of these pts.

    Objective. To assess the effects of the inactivated influenza virus vaccine on influenza outcomes in pregnant women and their infants. Methods. We performed a systematic review of the literature. We searched for randomized controlled trials and cohort studies in the MEDLINE, Embase, and other relevant databases (inception to September 2013). Two researchers selected studies and extracted the data independently. We used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to assess the quality of the evidence. Results. We included eight studies out of 1,967 retrieved records. Influenza vaccination in pregnant women significantly reduced the incidence of influenza-like illness in mothers and their infants when compared with control groups (high-quality evidence) and reduced the incidence of laboratory-confirmed influenza in infants (moderate-quality evidence). No difference was found with regard to influenza-like illness with fever higher than 38°C (moderate-quality evidence) or upper respiratory infection (very-low-quality evidence) in mothers and infants. Conclusions. Maternal vaccination against influenza was shown to prevent influenza-like illness in women and infants; no differences were found for other outcomes. As the quality of evidence was not high overall, further research is needed to increase confidence and could possibly change these estimates. PMID:24971194

    Background: In human, SRY (sex-determining region of the Y chromosome) is the major gene for the testis-determining factor which is found in normal XY males and in the rare XX males, and it is absent in normal XX females and many XY females. There are several methods which can indicate a male genotype by the presence of the amplified product of SRY gene. The aim of this study was to identify the SRY gene for embryo sex determination in human during pregnancy using loop mediated isothermal amplification (LAMP) method. Methods: A total of 15 blood samples from pregnant women at eight weeks of pregnancy were collected, and Plasma DNA was extracted. LAMP assay was performed using DNA obtained for detection of SRY gene. Furthermore, colorimetric LAMP assay for rapid and easy detection of SRY gene was developed. Results: LAMP results revealed that the positive reaction was highly specific only with samples containing XY chromosomes, while no amplification was found in samples containing XX chromosomes. A total of 15 blood samples from pregnant women were seven male embryos (46.6%) and eight female embryos (53.4%). All used visual components in the colorimetric assay could successfully make a clear distinction between positive and negative ones. Conclusion: The LAMP assay developed in this study is a valuable tool capable of monitoring the purity and detection of SRY gene for sex determination. PMID:28377900

    Background Human toxocariasis is a parasitic zoonosis with a worldwide distribution but is underdiagnosed with an underestimated impact on human health. The ingestion of embryonated eggs of Toxocara spp. present on the hands or in contaminated food or water is the main mode of infection. The only record of Toxocara congenital infection in humans occurred in a premature infant. Helminth infections during pregnancy may be associated with reproductive disorders. Studies investigating the occurrence of toxocariasis in pregnancy are scarce, as is research on the possible implications of these parasites in reproductive health. The aim of this study was to determine the seroprevalence of antibodies to Toxocara spp. in pregnant women and to identify risk factors associated with its infection. Methodology/Principal Findings The cross-sectional study of the seropositivity of specific antibodies for Toxocara spp. was performed on 280 pregnant women. Serum samples were examined with enzyme-linked immunoassay. Epidemiological data were obtained through a questionnaire containing information about obstetric history, general life style choices, and the social and economic status of the women. The prevalence of Toxocara spp. IgG in pregnant women was 6.4%. Some of the risk factors associated with the infection were owning dogs (p = 0.003), living in the city centre (p = 0.028), living at the city beach (p = 0.003), and having a family income at or below minimum wage (p < 0.001). There was no association between reproductive disorders and Toxocara seropositivity. Conclusions/Significance The seroprevalence of 6.4% for Toxocara spp. in pregnant women shows that there was exposure to the parasite. The study demonstrates the need for attention for the completion of clinical diagnosis parameters, as well as the expansion of highly specific serological studies in different regions to understand the impact of toxocariasis in pregnancy.

  14. Measuring cervical dilatation in human parturition using the Hall effect.

    PubMed

    Kriewall, T J; Work, B A

    1977-01-01

    An instrument was developed to continuously measure cervical dilatation in human labor. The instrument utilizes a small magnetic field source, which is attached to one edge of the cervix while a magnetic field sensor is attached to the diametrically opposite edge of the cervix. The sensor, using two Hall generators, measures orthogonal components of the field to minimize the effects of angular orientation between the source and sensor. The instrument's characteristics indicate that it can measure dilation throughout the range of 1-10 cm, but because its clinical reliability is consistent from only 1-7 cm, the equipment needs to be improved in the ways outlined in the text. This measurement, especially when analyzed with the continous measurement of intrauterine pressure, can provide the obstetrician with new insight into the physiology of labor.

    The aim of the present study was to evaluate the influence of pregnancy in adolescents on the fatty acid composition of the erythrocyte membrane, which was used as a proxy for status of n-3 and n-6 polyunsaturated fatty acids (PUFA), and also on the composition of plasma non-esterified fatty acids (NEFA) mobilized from the adipose tissue. Two matched groups of healthy adolescents (14-19 years) from Rio de Janeiro, Brazil, were compared: pregnant (n=26; 32.7+/-3.9 weeks of gestation, mean+/-SD) and non-pregnant (n=20). Blood samples were collected after an overnight fast. Mean dietary intakes of total fat and n-3 and n-6 PUFA (energy %) were not different between pregnant and non-pregnant adolescents, and the consumption of food sources of docosahexaenoic acid (DHA) was low. Fasting total NEFA and NEFA 18:2n-6, 18:3n-6 and 20:4n-6 (g/100g fatty acids) were higher in pregnant than in non-pregnant adolescents. Although erythrocyte 20:4n-6 was lower in pregnant adolescents, there were no differences in DHA (g/100g fatty acids), in DHA status indices (22:5n-6/22:4n-6 and 22:6n-3/22:5n-6 ratios) and in the index of n-3+n-6 PUFA status ([Sigman-3+Sigman-6]/[Sigman-7+Sigman-9]) in erythrocytes as compared with those of non-pregnant adolescents. In conclusion, pregnancy did not have an adverse effect on erythrocyte DHA content or on DHA and n-3+n-6 PUFA status indices in the adolescents studied.

    The involvement of endovascular trophoblast in fibrinoid deposition, replacement of the endothelium and vascular smooth muscle breakdown is studied in spiral arteries of the mesometrial triangle from day 15 to day 21 of rat pregnancy, by examining arterial cross sections after staining for cytokeratin, PAS, CD31 and alpha-actin. From day 15 to day 18 of pregnancy, fibrinoid deposition underneath the endovascular trophoblast increases gradually, whereas the amount of endovascular trophoblast in invaded arteries remains constant. CD31 staining is significantly reduced in sub-ET (= underlying the endovascular trophoblast) as compared to extra-ET (= outside the endovascular trophoblast) and no-ET (= non-invaded arterial sections) at each time-point of pregnancy examined (P < 0.005 and P < 0.0005 at each day of pregnancy), whereas alpha-actin staining is reduced both in sub-ET and in extra-ET as compared to no-ET. During pregnancy, CD31 staining in sub-ET initially declines, but increases significantly on day 21 (P < 0.001 versus d20) suggesting re-endothelialization of the vascular wall. In conclusion, changes in spiral arteries of pregnant rats reveal striking similarities with physiological changes seen in human pregnancy, thus emphasizing the usefulness of this species as an experimental model for studying normal and complicated pregnancies in humans.

  17. Levels of Urinary Metabolites of Organophosphate Flame Retardants, TDCIPP, and TPHP, in Pregnant Women in Shanghai

    Flame retardants are widely used in consumer products to reduce their flammability. Previously used flame retardants have been sequentially banned due to their environmental and human toxicity. Currently, tris(1,3-dichloropropyl) phosphate (TDCIPP) and triphenyl phosphate (TPHP) are among the most commonly used flame retardants. TDCIPP and TPHP are reproductive toxins and have carcinogenic, neurotoxic, and endocrine-disrupting properties. Although high levels of TDCIPP and TPHP have been found in drinking water, seawater, and office air in China, data regarding human exposure are lacking. In this study, we assessed the level of urinary TPHP and TDCIPP metabolites (DPHP and BDCIPP, resp.) in a cohort of pregnant women (N = 23) from Shanghai, China, using liquid chromatography-tandem mass spectrometry. DPHP were detected in 100% urine samples, while only four urine samples had detectable level of BDCIPP in this cohort (17% detected). Geometric means of DPHP and BDCIPP concentrations were 1.1 ng/mL (interquartile range [IQR]: 0.6, 1.5 ng/mL) and 1.2 ng/mL (IQR: 0.6, 2.2 ng/mL), respectively. In this small cohort, urinary DPHP and BDCIPP levels were not significantly correlated with miscarriages, neonatal birthweight, gestational diabetes, or maternal age. These data suggest that exposure to TPHP is widespread, and they demonstrate the feasibility of using urinary biomarkers to measure exposures to modern flame-retardant chemicals. PMID:28115951

    The aim of the study was to evaluate the effect of forearm support provided by the Workplace Board on perceived tension, comfort and productivity among pregnant and non-pregnant female computer workers. Ten pregnant and 18 non-pregnant women participated in the study. Participants completed three sets of tension/discomfort questionnaires at two week intervals. The first set was completed prior to any workstation intervention; the second set was completed after two weeks working with an ergonomically adjusted workstation; the third set was completed after two weeks working with the Workplace Board integrated into the office workstation. With the Workplace Board, decreased perceived tension was reported in the left shoulder, wrist and low back in non-pregnant women only. The Board was generally liked by all participants, and increased comfort and productivity in all areas, with the exception of a negative effect on productivity of general office tasks. The board is suitable for integration in most office workstations and for most users, but has no special benefits for pregnant women.

    Fifteen pregnant Holstein cows were freely assigned to 3 experimental groups (5 cows in each group). Cows in group I were inoculated IM and intramammarily (IMm) with Ohio Agricultural Research and Development Center (OARDC) tissue culture-propagated modified-live Nebraska calf diarrhea bovine rotavirus with added adjuvant (OARDC vaccine-immunized cows). Group II cows were given IM injections of a commercial modified-live rotavirus-coronavirus vaccine (commercial vaccine-immunized cows), and the remaining 5 cows were noninoculated controls (group III). Rotavirus antibody in colostrum and milk was mainly associated with immunoglobulin (Ig)G1, and less so with IgG2, IgA, and IgM, as analyzed by the enzyme-linked immunosorbent assay (ELISA), using monospecific anti-bovine IgG1, IgG2, IgM, and IgA sera. In serum, the rotavirus antibody was distributed almost equally between IgG1 and IgG2. The same relationships appeared in both immunized and nonvaccinated cows. All OARDC vaccine-injected cows had virus-neutralization (VN) and ELISA IgG1 rotavirus antibody titers in serum and mammary secretions at significantly increased levels (at least 100-fold; P less than 0.05) compared with the titers in groups II (commercial vaccine-immunized cows) and III (controls). Serum, colostrum, and milk antibody titers from these latter 2 groups did not differ statistically. The ELISA IgG2, IgA, and IgM rotavirus antibody titers also were significantly greater in mammary secretions from OARDC vaccine-immunized cows than in groups II and III cows. There was a high correlation between ELISA IgG1 and VN rotavirus antibody titers for all samples tested (r = 0.97, P less than 0.001), but ELISA IgG1 antibody titers were consistently higher than VN titers. The ELISA IgG1 and VN antibody titers of milk samples collected from cows 30 days after parturition were higher from the OARDC vaccine-immunized cows (ELISA IgG1, geometric mean titer (GMT) = 3,511; VN GMT = 1,689) than were titers from the

    The influence of purified porcine relaxin on contractility of human cervical smooth muscle was investigated in vitro. Strips of cervical tissue were obtained by needle biopsy from pregnant and nonpregnant women and were mounted in a superfused organ chamber for isometric measurement of contractile activity. Relaxin (0.005-25 micrograms/ml) inhibited the spontaneous contractions in cervical strips from 18% of nonpregnant, 68% of early pregnant, and in 100% of term pregnant women. These results indicate that relaxin has an inhibitory action on cervical smooth muscle and that this effect is more constantly detected as pregnancy proceeds.

    2015-05-01

    The aim of the study was to identify knowledge and fear related to childbirth and the postpartum period in pregnant women. The sample consisted of 114 pregnant women. It was determined that pregnant women had insufficient levels of knowledge related to childbirth and the postpartum period. The Fear of Childbirth and Postpartum Anxiety Scale score for childbirth and the postpartum period related to 'fear regarding the action of childbirth', was found to be the highest. The highest causes for concern were determined to be 'infant-related anxiety' and 'fear regarding infant and puerperal health'. No statistically significant correlation was observed between the perceived sufficiency of the knowledge of pregnant women in terms of maintaining their own health and care, and their mean childbirth and postpartum period concern score. These findings indicate that the level of concern among pregnant women with relation to the postpartum period and childbirth is rather high.

    The constitutive androstane receptor (CAR) has been reported to decrease insulin resistance along with obesity. 6,7-dimethylesculetin (DE) is an active component of Yin Zhi Huang which is a traditional Asian medicine used to treat neonatal jaundice via CAR. In this study, we examined whether DE could affect the expression of gluconeogenic and lipogenic genes via human CAR pathway using human HepG2 cells in vitro. We also studied whether DE treatment during pregnancy could prevent maternal hypertension, glucose intolerance and hyperlipidemia, and fetal overgrowth in high-fat diet (HFD)-induced obese pregnant mice. Dimethylesculetin suppressed the mRNA expression of gluconeogenic genes, phosphoenolpyruvate carboxykinase and glucose-6-phosphatase, and lipogenic genes, sterol regulatory element-binding protein 1 and stearoyl-CoA desaturase 1, and enhanced CAR-mediated transcription. Blocking the CAR-mediated pathway abolished the effect of DE in vitro. DE treatment during pregnancy could prevent maternal hypertension, glucose intolerance and hyperlipidemia, and fetal overgrowth in HFD-induced obese pregnant mice in vivo. Our data indicate that DE might be a potential therapeutic agent for obese pregnant patients with insulin resistance through CAR to prevent the perinatal outcomes such as preeclampsia, gestational diabetes, and macrosomia. Further analysis of possible complications and side effects using animal models is required.

    OBJECTIVES: Microwaves produce various detrimental changes based on actions of heat or non-specific stress, although the effects of microwaves on pregnant organisms has not been uniform. This study was designed to clarify the effect of exposure to microwaves during pregnancy on endocrine and immune functions. METHODS: Natural killer cell activity and natural killer cell subsets in the spleen were measured, as well as some endocrine indicators in blood--corticosterone and adrenocorticotrophic hormone (ACTH) as indices of the hypothalamic-pituitary-adrenal axis--beta-endorphin, oestradiol, and progesterone in six female virgin rats and six pregnant rats (nine to 11 days gestation) exposed to microwaves at 10 mW/cm2 incident power density at 2450 MHz for 90 minutes. The same measurements were performed in control rats (six virgin and six pregnant rats). RESULTS: Skin temperature in virgin and pregnant rats increased immediately after exposure to microwaves. Although splenic activity of natural killer cells and any of the subset populations identified by the monoclonal antibodies CD16 and CD57 did not differ in virgin rats with or without exposure to microwaves, pregnant rats exposed to microwaves showed a significant reduction of splenic activity of natural killer cells and CD16+CD57-. Although corticosterone and ACTH increased, and oestradiol decreased in exposed virgin and pregnant rats, microwaves produced significant increases in beta-endorphin and progesterone only in pregnant rats. CONCLUSIONS: Microwaves at the power of 10 mW/cm2 produced activation of the hypothalamic-pituitary-adrenal axis and increased oestradiol in both virgin and pregnant rats, suggesting that microwaves greatly stress pregnant organisms. These findings in pregnant rats suggest that--with exposure to microwaves--pregnancy induces immunosuppression, which could result in successful maintainance of pregnancy. This enhancement of adaptability to heat stress with pregnancy may be mediated by

    Deep venous thrombosis of the lower extremities is an uncommon but dreaded complication of pregnancy which can present diagnostic and therapeutic problems to the treating physician. From January 1, 1985, to December 31, 1988, 7867 deliveries were performed at St. Luke's Hospital. Five of these patients were pregnant women who were treated for deep venous thrombosis of the lower extremities. The women were either in their second or third trimester of pregnancy. The clinical diagnosis in each case was confirmed with duplex ultrasonography. Each patient was treated with 7 to 10 days of intravenous heparin therapy and then discharged on subcutaneous heparin therapy. There were no bleeding complications related to the heparin therapy. No patient developed a pulmonary embolism. Each patient delivered a normal child. The only complication was a heparin induced rash in one patient which resolved when a different preparation of heparin was used. The management of deep venous thrombosis in pregnancy is discussed.

    Uterine torsion is defined as a rotation of the uterus of more than 45° along its long axis. It is a rare complication during pregnancy; a common cause of torsion can be uterine myoma. Here we describe the case of a 27-year-old G2P1+0 woman at 15 weeks 3 day pregnancy, who presented to our outpatient department as a case of acute abdomen, in a state of shock. Clinical findings did not correlate with investigation. On lapratomy she was diagnosed as a case of complete axial torsion of pregnant uterus with fundal myoma with massive abruption. Early diagnosis and timely intervention would help in improving both maternal and fetal outcome. PMID:25193815

    We conducted a review of literature related to radiation effects on pregnant women, fetuses, and children from the perspective of epidemiology, pathology, and radiobiology. During 8-25 weeks post-conception the central nervous system is particularly sensitive to radiation. Fetal doses in excess of 100 mGy can result in some reduction of IQ (intelligence quotient). Fetal doses in the range of 1000 mGy can lead to severe mental retardation and microcephaly, particularly during 8-15 weeks and to a lesser extent 16-25 weeks after conception. Recent studies of cancers and chromosome aberrations indicated less radiosensitivity in prenatally exposed A-bomb survivors compared with postnatally exposed survivors, for which we provide possible hypotheses as an explanation.

    The relationship between the vitamin B6 status of 180 pregnant women and the incidence and degree of morning sickness experienced during the first trimester was investigated. There were no significant differences in plasma pyridoxal 5'-phosphate (PLP), erythrocyte aspartate aminotransferase (AspAT) activity, and stimulation of erythrocyte AspAT activity by exogenous PLP between subjects who experienced morning sickness and those who did not. No relationship was found between these indicators of vitamin B6 status and the degree of morning sickness experienced by this group during early pregnancy. There were no differences in the number of women who experienced morning sickness or in the number with different degrees of sickness when plasma levels of PLP, erythrocyte AspAT activity or stimulation by PLP were divided into upper and lower 50th percentile groups and compared. Therefore these data show no relationship between vitamin B6 status and the incidence or degree of morning sickness.

    Many mammals save energy during food shortage or harsh weather using controlled reductions in body temperature and metabolism called torpor. However, torpor slows offspring growth, and reproductive individuals are thought to avoid using it because of reduced fitness resulting from delayed offspring development. We tested this hypothesis by investigating torpor during reproduction in hoary bats ( Lasiurus cinereus, Vespertilionidae) in southern Canada. We recorded deep, prolonged torpor bouts, which meet the definition for hibernation, by pregnant females. Prolonged torpor occurred during spring storms. When conditions improved females aroused and gave birth within several days. Our observations imply a fitness advantage of torpor in addition to energy conservation because reduced foetal growth rate could delay parturition until conditions are more favourable for lactation and neonatal survival.

    Cystic Fibrosis (CF) is a multisystem disease predominantly affecting the airways and predisposing patients to recurrent infections with various multidrug resistant organisms. Mycobacterium tuberculosis (MTB) infection is rarely seen, but considered a potential pathogen in CF patients. We report a 26 year old pregnant CF patient on Ivacaftor who was admitted with symptoms suggestive of tuberculosis. Three years prior to the current admission, she had completed four drug anti- MTB therapy for pulmonary tuberculosis and was considered cured as her sputum cultures after six months of treatment were negative. Genotype analysis revealed the current MTB strain to be different from the strain causing the previous infection. After receiving first line anti-tuberculous regimen for nine months, the patient's condition markedly improved culminating in an uneventful pregnancy and delivery. To our knowledge, this is the only reported case of reinfection tuberculosis in a CF patient. PMID:26744656

  14. Are pregnant and postpartum women: at increased risk for violent death? Suicide and homicide findings from North Carolina.

    The purpose of this study is to estimate rates of suicide and homicide death among pregnant, postpartum and non-pregnant/non-postpartum women ages 14-44, and to determine comparative rates of violent death for pregnant and/or postpartum women compared to non-pregnant/non-postpartum women. North Carolina surveillance and vital statistics data from 2004 to 2006 were used to examine whether pregnant or postpartum women have higher (or lower) rates of suicide and homicide compared to other reproductive-aged women. The suicide rate for pregnant women was 27% of the rate for non-pregnant/non-postpartum women (rate ratio= 0.27, 95% CI = 0.11-0.66), and the suicide rate for postpartum women was 54% of the rate for non-pregnant/non-postpartum women (rate ratio = 0.54, 95% CI = 0.31-0.95). Homicide rates also were lower for pregnant and postpartum women, with the homicide rate for pregnant women being 73% of the rate for non-pregnant/non-postpartum women (rate ratio = 0.73, 95% CI = 0.39-1.37), and the homicide rate for postpartum women being half the rate for non-pregnant/non-postpartum women (rate ratio = 0.50, 95% CI = 0.26-0.98). Although pregnant and postpartum women are at risk for homicide and suicide death, the highest risk group is non-pregnant/non-postpartum women. Violence prevention efforts should target all women of reproductive age, and pay particular attention to non-pregnant/non-postpartum women, who may have less access to health care services than pregnant and postpartum women.

    The mechanism of action of leptin in pregnant breeding sows, in which hyperphagia is managed through dietary strategies, is yet to be clarified. The aim of this study was to monitor leptin concentrations and their interactions with lactogenic hormones in Large White×Landrace breeding multiparous sows (n=15). All sows showed a normal body condition (mean body condition score: 2.96). Blood samples were collected the day after weaning the litters, at insemination, every 15 days up to day 45 of pregnancy and every 7 days from day 46 to farrowing. At delivery, the placenta was collected for the analysis of leptin and leptin receptor expressions. Plasma leptin levels increased from the end of mid gestation (day 72) and remained high until farrowing (P<0.05). As expected, plasma prolactin (PRL), low during most of pregnancy, increased during the 2 weeks before farrowing (P<0.05), whereas progesterone levels reached plateau at 30 days of gestation and decreased at farrowing (P<0.05). Cortisol levels peaked close to farrowing (P<0.05). Leptin was expressed in the placenta, where the receptor expression analysis showed the presence of the short form but not of the long form. A positive correlation was found between leptin and PRL concentrations during mid (r=0.430; P<0.001) and late (r=0.687; P<0.001) pregnancy, and with progesterone in early pregnancy (r=0.462; P<0.05). During late gestation, a positive correlation was observed between leptin and cortisol (r=0.585; P<0.001). Our results suggested that, in restrictively fed pregnant sows, the leptin levels increased from the end of mid pregnancy to delivery, confirming the presence of leptin resistance. We showed a correlation between leptin and lactogenic hormones during different stages of pregnancy in sows. Lactogenic hormones show pregnancy-specific changes in their secretion and all may become involved in modulating leptin signal.

    Objective The purpose of this study was to evaluate the perinatal outcomes in pregnant women who use illicit drugs. Methods A retrospective observational study of patients who, at the time of delivery, were sent to or who spontaneously sought a public maternity hospital in the eastern area of São Paulo city. We compared the perinatal outcomes of two distinct groups of pregnant women - illicit drugs users and non-users - that gave birth in the same period and analyzed the obstetric and neonatal variables. We used Student's t-test to calculate the averages among the groups, and the Chi-square test or Fisher's exact test to compare categorical data from each group. Results We analyzed 166 women (83 users and 83 non-users) in both groups with a mean of age of 26 years. Ninety-five percent of the drug users would use crack or pure cocaine alone or associated with other psychoactive substances during pregnancy. Approximately half of the users group made no prenatal visit, compared with 2.4% in the non-users group (p < 0.001). Low birth weight (2,620 g versus 3,333 g on average, p < 0.001) and maternal syphilis (15.7% versus 0%, p < 0.001) were associated with the use of these illicit drugs. Conclusions The use of illicit drugs, mainly crack cocaine, represents an important perinatal risk. Any medical intervention in this population should combine adherence to prenatal care with strategies for reducing maternal exposure to illicit drugs.

    Objectives Actively recruit and intensively follow pregnant women receiving a dose of acellular pertussis vaccine for 4 weeks after vaccination. Design and settings A prospective observational study conducted in 2 New Zealand regions. Participants Women in their 28th–38th week of pregnancy, recruited from primary care and antenatal clinics at the time of Tdap administration. Telephone interviews were conducted at 48 h and 4 weeks postvaccination. Main outcomes measures Outcomes were injection site reactions, systemic symptoms and serious adverse events (SAEs). Where available, data have been classified and reported according to Brighton Collaboration definitions. Results 793 women participated with 27.9% receiving trivalent inactivated influenza vaccine concomitantly. 79% of participants reported mild or moderate pain and 2.6% severe pain. Any swelling was reported by 7.6%, induration by 12.0% (collected from 1 site only, n=326), and erythema by 5.8% of participants. Fever was reported by 17 (2.1%) participants, 14 of these occurred within 24 h. Headache, dizziness, nausea, myalgia or arthralgia was reported by <4% of participants, respectively, and fatigue by 8.4%. During the study period, there were 115 adverse events in 113 participants, most of which were minor. At the end of the reporting period, 31 events were classified as serious (eg, obstetric bleeding, hypertension, infection, tachycardia, preterm labour, exacerbation of pre-existing condition and pre-eclampsia). All had variable onset time from vaccination. There were two perinatal deaths. Clinician assessment of all SAEs found none likely to be vaccine related. Conclusions Vaccination with Tdap in pregnant women was well tolerated with no SAE likely to be caused by the vaccine. Trial registration number ACTRN12613001045707. PMID:27091823

  18. Metabolic Equivalent in Adolescents, Active Adults and Pregnant Women

    “Metabolic Equivalent” (MET) represents a standard amount of oxygen consumed by the body under resting conditions, and is defined as 3.5 mL O2/kg × min or ~1 kcal/kg × h. It is used to express the energy cost of physical activity in multiples of MET. However, universal application of the 1-MET standard was questioned in previous studies, because it does not apply well to all individuals. Height, weight and resting metabolic rate (RMR, measured by indirect calorimetry) were measured in adolescent males (n = 50) and females (n = 50), women during pregnancy (gestation week 35–41, n = 46), women 24–53 weeks postpartum (n = 27), and active men (n = 30), and were compared to values predicted by the 1-MET standard. The RMR of adolescent males (1.28 kcal/kg × h) was significantly higher than that of adolescent females (1.11 kcal/kg × h), with or without the effects of puberty stage and physical activity levels. The RMR of the pregnant and post-pregnant subjects were not significantly different. The RMR of the active normal weight (0.92 kcal/kg × h) and overweight (0.89 kcal/kg × h) adult males were significantly lower than the 1-MET value. It follows that the 1-MET standard is inadequate for use not only in adult men and women, but also in adolescents and physically active men. It is therefore recommended that practitioners estimate RMR with equations taking into account individual characteristics, such as sex, age and Body Mass Index, and not rely on the 1-MET standard.

    Polychlorinated biphenyls (PCBs) are widespread persistent residual environmental pollutants, which affect seriously the growth and reproductive alterations in humans and animals. Aroclor 1254 is a commercial mixture of PCBs. Quercetin is a flavonoid, which acts on estrogen receptors and causes the development of estrogen-related diseases. In this paper, the primary cultured endometrial cells in the pregnant rats were isolated and Aroclor 1254 was used to induce the injured endometrial cells model. The cells were treated with gradient quercetin, the viability of the endometrial cells, the expressions of CYP450, the contents of TNF-α, IL-6, estradiol (E2), and progesterone (P4) were measured. It showed that the viability of the cultured endometrial cells, the expression of CYP1A1 and CYP2B1, and the contents of TNF-α, E2, and IL-6 in the injured endometrial cells increased with the treatment of quercetin. It shows that quercetin has protective effect on the injured endometrial cells in the pregnant rats, this provide a basis on herbal medicine protection for animal reproductive diseases caused by environmental endocrine disruptors.

    Puerto Rico has higher rates of a range of endocrine-related diseases and disorders compared to the United States. However, little is known to date about human exposures to known or potential endocrine disrupting chemicals (EDCs) in Puerto Rico. We recruited 105 pregnant women in Northern Puerto Rico who provided urine samples and questionnaire data at three times (18 ± 2, 22 ± 2, and 26 ± 2 weeks) during gestation. We measured the urinary concentrations of five phenols and three parabens: 2,4-dichlorophenol (24-DCP), 2,5-dichlorophenol (25-DCP), benzophenone-3 (BP-3), bisphenol A (BPA), triclosan (TCS), butyl paraben (B-PB), methyl paraben (M-PB), and propyl paraben (P-PB). The frequent detection of these chemicals suggests that exposure is highly prevalent among these Puerto Rican pregnant women. Urinary concentrations of TCS, BP-3, and 25-DCP were higher than among women of reproductive age in the US general population, while concentrations of BPA, 24-DCP, and parabens were similar. Intraclass correlation coefficients (ICC) varied widely between biomarkers; BPA had the lowest ICC (0.24) and BP-3 had the highest (0.62), followed by 25-DCP (0.49) and TCS (0.47). We found positive associations between biomarker concentrations with self-reported use of liquid soap (TCS), sunscreen (BP-3), lotion (BP-3 and parabens), and cosmetics (parabens). Our results can inform future epidemiology studies and strategies to reduce exposure to these chemicals or their precursors.

  10. Innate immune performance and steroid hormone profiles of pregnant versus nonpregnant cottonmouth snakes (Agkistrodon piscivorus).

    Squamates (lizards and snakes) have independently evolved viviparity over 100 times, and exhibit a wide range of maternal investment in developing embryos from the extremes of lecithotrophic oviparity to matrotrophic viviparity. This group therefore provides excellent comparative opportunities for studying endocrine and immune involvement during pregnancy, and their possible interactions. We studied the cottonmouth (Agkistrodon piscivorus), since they exhibit limited placentation (e.g., ovoviviparity), allowing comparison with squamate species hypothesized to require considerable maternal immune modulation due to the presence of a more extensive placental connection. Furthermore, the cottonmouth's biennial reproductive cycle provides an opportunity for simultaneously comparing pregnant and non-pregnant females in the wild. We document significantly elevated concentrations of progesterone (P4) and significantly lower concentrations of estradiol (E2) in pregnant females relative to non-pregnant females. Pregnant females had lower plasma bacteria lysis capacity relative to non-pregnant females. This functional measure of innate immunity is a proxy for complement performance, and we also determined significant correlations between P4 and decreased complement performance in pregnant females. These findings are consistent with studies that have determined P4's role in complement modulation during pregnancy in mammals, and thus this study joins a growing number of studies that have demonstrated convergent and/or conserved physiological mechanisms regulating viviparous reproduction in vertebrates.

    The present study aimed to evaluate the safety of the classical swine fever virus (CSFV) vaccine strain LOM in pregnant sows. Pregnant sows with free CSFV antibody were inoculated with a commercial LOM vaccine during early pregnancy (day 38; n=3) or mid-pregnancy (days 49-59; n=11). In pregnant sows vaccinated during the early stages of gestation, abortion (day 109) was observed in one case, with two stillbirths and seven mummified fetuses. The viability of live-born piglets was 34.9% in sows vaccinated during mid-pregnancy compared with 81.8% in the control group. Post-mortem examination of the organs of the sows and piglets did not reveal any pathological lesions caused by CSFV; however, CSFV RNA was detected in the organs of several vaccinated sows and their litters. The LOM strain was transmitted from sows with free CSFV antibody to their fetus, but did not appear to induce immune tolerance in the offspring from vaccinated pregnant sows. Side effects were not observed in pregnant sows with antibody to the LOM strain: transmission from sow to their litters and stillbirth or mummified fetuses. The LOM strain may induce sterile immunity and provide rapid, long-lasting, and complete protection against CSFV; however, it should be contraindicated in pregnant sows due to potential adverse effects in pregnant sows with free CSFV antibody.

  12. Pregnancy and Protection: The Ethics of Limiting a Pregnant Woman’s Participation in Clinical Trials

    Allesee, Lori; Gallagher, Colleen M.

    2011-01-01

    The call for the inclusion of pregnant women in clinical trials has received renewed attention recently. This interest springs from articles in various medical journals highlighting the gaps in medical knowledge and the need to improve health care for pregnant women. It is not a simple decision whether to include pregnant women in studies or not. The general thought is that it’s too dangerous for the baby if a pregnant woman is participating in a trial, and the absence of research on how medications work in pregnant women leave doctors guessing about how to safely and effectively treat patients through pregnancy. Excluding pregnant women from clinical trials are not automatic, not unethical nor is it arbitrarily determined. The regulatory framework is based on sound ethical and legal reasoning that demonstrates when inclusion in a clinical trial is appropriate or when clear and compelling reasons for exclusion are presented. Learning objective Readers will learn about limitations of research, history of the inclusion and exclusion of pregnant women in clinical trials, reticence for inclusions, as well as regulations designed using reasoned legal and ethical principles, such as: Principle of Autonomy, Informed Consent, and Beneficence and Nonmaleficence.

    The aim of this study is to report how pregnancy alters hematology and clinical chemistry values in rats. Female and male Sprague-Dawley rats were mated; the day of copulation was designated as Day 0. Hematology and clinical chemistry measurements were conducted on Days 7, 14, 17 and 21 in pregnant rats. Measurements were also conducted in non-pregnant rats. Red blood cells (RBC), hemoglobin (Hb), hematocrit (Ht), total protein and albumin decreased on Days 7, 14, 17 and 21; sodium, chloride and glucose decreased on Days 14, 17 and 21; iron decreased on Days 17 and 21; hemoglobin content of reticulocytes (CHr), calcium, inorganic phosphorus and the albumin/globulin ratio decreased on Day 21; and total cholesterol, phospholipid and high-density lipoprotein cholesterol decreased on Day 14 in pregnant rats compared with non-pregnant rats. Reticulocyte increased on Days 7, 14 and 17; mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, neutrophil count and rate increased on Days 14, 17 and 21; platelets, fibrinogen, triglyceride and free fatty acid increased on Days 17 and 21; and activated partial thromboplastin time was prolonged on Days 17 and 21 in pregnant rats compared with non-pregnant rats. The decreased RBC, Hb, Ht, CHr and iron in pregnant rats indicated that they suffered from iron deficiency anemia. These data can be used as background information for effective evaluation in reproductive toxicology studies.

  14. [What determines smoking habits in pregnancy? A qualitative study among pregnant smokers].

    PubMed

    Haugland, S; Haug, K; Wold, B

    1995-06-30

    In this article we present results from a qualitative study among 33 pregnant smokers, who took part in an in-depth interview in the 27th-35th weeks of pregnancy. The aim was to obtain insight into pregnant women's own experience of smoking in pregnancy. The pregnant women interviewed were concerned about their smoking habits. In spite of this, they still expressed positive attitudes towards smoking, and many did not experience pregnancy as a favourable time to stop. The study shows that pregnant women still lack important knowledge about the dangers of smoking. Pregnant smokers' attitudes towards scientific facts, and the role cigarettes play in their everyday lives, are considered to be important variables in determining smoking in pregnancy. The pregnant women experienced that their partner and health-personnel played a minor role in changing smoking behaviour. The reasons the women gave for smoking in pregnancy are discussed in the light of current theories on changing health behaviour. Four key questions are proposed which can be used by doctor and midwife to obtain knowledge of pregnant women's perception of the seriousness of smoking and the associated risks, and of the gains and barriers connected with quitting.

    Background The epidemiology of adjustment disorder in pregnant women is largely unknown. We sought to determine the prevalence and correlates of adjustment disorder in pregnant women in Durango City, Mexico. Methods Pregnant women (n = 300) attending in a public hospital in Durango City, Mexico were studied. All enrolled pregnant women had a psychiatric interview to evaluate the presence of adjustment disorder using the DSM-IV criteria. A questionnaire was submitted to obtain general epidemiological data of the pregnant women studied. Bivariate and multivariate analyses were used to assess the association of adjustment disorder with the epidemiological data of the women studied. Results Fifteen (5.0%) of the 300 women studied had adjustment disorder according to the DSM-IV criteria. Adjustment disorder was not associated with age, occupation, marital status, or education of pregnant women. In contrast, multivariate analysis of socio-demographic, clinical and psychosocial variables showed that adjustment disorder was associated with the variables lack of support from her couple (odds ratio (OR) = 3.83; 95% confidence interval (CI): 1.00 - 14.63; P = 0.04) and couple living abroad (OR = 10.12; 95% CI: 1.56 - 65.50; P = 0.01). Conclusions This is the first report about the epidemiology of adjustment disorder in pregnant women in Mexico. Results provide evidence of the presence of adjustment disorder and contributing psychosocial factors associated with this disorder in pregnant women in Mexico. Results point towards further clinical and research attention should be given to this neglected disorder in pregnant women. PMID:26346070

    Background The seroepidemiology of rubella virus infection in pregnant women in northern Mexico is largely unknown. We sought to determine the seroprevalence of rubella virus infection in pregnant women in the northern Mexican city of Durango, Mexico. Seroprevalence association with the socio-demographic, clinical and behavioral characteristics of the pregnant women was also investigated. Methods Through a cross-sectional study, we determined the seroprevalence of IgG and IgM anti-rubella virus in 279 pregnant women (mean age 29.17 ± 5.96 years; range 15 - 43 years) attending in a clinic of family medicine using enzyme-linked fluorescent assays. A questionnaire was used to obtain the socio-demographic, clinical and behavioral characteristics of the pregnant women. The association of rubella seropositivity and characteristics of the women was assessed by bivariate and multivariate analyses. Results Anti-rubella IgG antibodies (≥ 15 IU/mL) were found in 271 (97.1%) of the 279 pregnant women examined. None of the 279 pregnant women were positive for anti-rubella IgM antibodies. Multivariate analysis of socio-demographic, clinical and behavioral variables showed that seroreactivity to rubella virus was positively associated with national trips (OR = 7.39; 95% CI: 1.41 - 38.78; P = 0.01), and negatively associated with age (OR = 0.26; 95% CI: 0.06 - 0.99; P = 0.04). Conclusions Rate of rubella immunity in pregnant women in the northern Mexican city of Durango is high. However, nearly 3% of pregnant women are susceptible to rubella in our setting. Risk factors associated with rubella seropositivity found in this study may be useful for optimal design of preventive measures against rubella and its sequelae. PMID:27540439

    This study proposed to broadly examine vehicle use by pregnant women in order to improve realism of accident simulations involving these particular occupants. Three research pathways were developed: the first consisted in a questionnaire survey examining the driving habits of 135 pregnant women, the second obtained measurements of 15 pregnant women driving position in their own vehicle from the 6th to the 9th month of pregnancy by measuring distances between body parts and vehicle parts, and the third examined car accidents involving pregnant occupants. Results obtained indicate that between 90% and 100% of pregnant women wore their seat belts whatever their stage of pregnancy, although nearly one third of subjects considered the seat belt was dangerous for their unborn child. The measurements obtained also showed that the position of the pregnant woman in her vehicle, in relation to the various elements of the passenger compartment, changed significantly during pregnancy. In the studied accidents, no correlation was found between the conditions of the accident and the resulting fetal injury. Results reveal that pregnant women do not modify significantly the seat setting as a function of pregnancy stage. Only the distance between maternal abdomen and steering wheel change significantly, from 16 cm to 12 cm at 6 and 9 month respectively. Pregnant women are mainly drivers before 8 months of pregnancy, passengers after that. Car use frequency falls down rapidly from 6 to 9 months of pregnancy. Real crashes investigations indicate a low rate of casualties, i.e. 342 car accidents involving pregnant women for a period of 9 years in an approximately 1.7 million inhabitants area. No specific injury was found as a function of stage of pregnancy.

    2,3,3,3-Tetrafluoropropene (HFO-1234yf) is a novel refrigerant intended for use in mobile air conditioning. It showed a low potential for toxicity in rodents studies with most NOAELs well above 10,000 ppm in guideline compliant toxicity studies. However, a developmental toxicity study in rabbits showed mortality at exposure levels of 5,500 ppm and above. No lethality was observed at exposure levels of 2,500 and 4,000 ppm. Nevertheless, increased subacute inflammatory heart lesions were observed in rabbits at all exposure levels. Since the lethality in pregnant animals may be due to altered biotransformation of HFO-1234yf and to evaluate the potential risk to pregnant women facing a car crash, this study compared the acute toxicity and biotransformation of HFO-1234yf in male, female and pregnant female rabbits. Animals were exposed to 50,000 ppm and 100,000 ppm for 1 h. For metabolite identification by {sup 19}F NMR and LC/MS-MS, urine was collected for 48 h after inhalation exposure. In all samples, the predominant metabolites were S-(3,3,3-trifluoro-2-hydroxypropanyl)-mercaptolactic acid and N-acetyl-S-(3,3,3-trifluoro-2-hydroxypropanyl)-L-cysteine. Since no major differences in urinary metabolite pattern were observed between the groups, only N-acetyl-S-(3,3,3-trifluoro-2-hydroxypropanyl)-L-cysteine excretion was quantified. No significant differences in recovery between non-pregnant (43.10 ± 22.35 μmol) and pregnant female (50.47 ± 19.72 μmol) rabbits were observed, male rabbits exposed to 100,000 ppm for one hour excreted 86.40 ± 38.87 μmol. Lethality and clinical signs of toxicity were not observed in any group. The results suggest that the lethality of HFO-1234yf in pregnant rabbits unlikely is due to changes in biotransformation patterns or capacity in pregnant rabbits. -- Highlights: ► No lethality and clinical signs were observed. ► No differences in metabolic pattern between pregnant and non-pregnant rabbits. ► Rapid and similar metabolite

  19. Cigarette smoking in pregnant substance users: Association with substance use and desire to quit.

    Cigarette smoking is prevalent in pregnant substance users but receives low priority in substance use disorder treatment. This article reports the results of a secondary analysis of a randomized, multisite trial with 200 pregnant substance users, 145 (72.5%) of whom smoked at baseline. As predicted: (1) smokers had significantly greater substance use; (2) approximately half of smokers wanted to quit; and (3) smokers with a quit goal had significantly greater self-efficacy and lower perceived difficulty of quitting. Smoking may be associated with more severe substance use in pregnant substance-using patients, half of whom may be interested in smoking-cessation interventions.

    This is a review of Medline and PubMed articles on venomous animal bites and stings during pregnancy reported in English literature from 1966 to 2002. Eighty-five venomous snakebites were reported in pregnant women. Although there are frequent anecdotal reports of scorpion stings in pregnant women, few case reports are documented. Other venomous animal bites or stings to pregnant women that have been reported include spiders, jellyfish, and insects, and these are described. Adverse reproductive and teratogenic effects of venoms on gravid animals are also briefly reviewed. Although uncommon, venomous bites and stings during pregnancy may have significant adverse effects on the fetus and the mother.

    Following our study of attitudes, barriers, and intentions concerning the influenza vaccination among pregnant women in South Korea, we discovered that women displaying a more positive attitude toward the influenza vaccination were more likely to receive it during their pregnancy. We also found that attitudes toward vaccination were more positive among vaccinated pregnant women than among those who were unvaccinated. Furthermore, women showed a greater intention to get vaccinated if a clinician, rather than friends, recommended it. The major perceived barriers to receiving an influenza vaccination were being pregnant, fearing harm to the baby, feeling healthy, and thinking it is unnecessary.

    Pregnant women in methadone maintenance therapy may have poor nutrition during pregnancy. In 2006–2008, methadone treated pregnant women (n = 22) were recruited at an urban academic medical center and compared with non-drug using pregnant women (n = 119) at 20–35 weeks gestation. We measured adiposity using pre-pregnancy body mass index (BMI), dietary intake using a food frequency questionnaire, and micronutrient and essential fatty acid status using biomarkers. Methadone treated women had lower BMI, consumed more calories, had lower serum carotenoid concentrations and higher plasma homocysteine concentrations than controls. The study’s limitations and implications for future research are discussed. PMID:22217127

    Human phthalate exposure is ubiquitous, but little is known regarding predictors of urinary phthalate levels. To explore this, 50 pregnant women aged 18-38 years completed two questionnaires on potential phthalate exposures and provided a first morning void. Urine samples were analyzed for 12 phthalate metabolites. Associations with questionnaire items were evaluated via Wilcoxon tests and t-tests, and r-squared values were calculated in multiple linear regression models. Few measured factors were statistically significantly associated with phthalate levels. Individuals who used nail polish had higher levels of mono-butyl phthalate (P=0.048) than non-users. Mono-benzyl phthalate levels were higher among women who used eye makeup (P=0.034) or used makeup on a regular basis (P=0.004). Women who used cologne or perfume had higher levels of di-(2-ethylhexyl) phthalate metabolites. Household products, home flooring or paneling, and other personal care products were also associated with urinary phthalates. The proportion of variance in metabolite concentrations explained by questionnaire items ranged between 0.31 for mono-ethyl phthalate and 0.42 for mono-n-methyl phthalate. Although personal care product use may be an important predictor of urinary phthalate levels, most of the variability in phthalate exposure was not captured by our relatively comprehensive set of questionnaire items.

    The application of assisted reproductive technologies (ART) to nonhuman primates has created opportunities for improving reproductive management in breeding colonies, and for creation of new animal models by genetic modification. One impediment to the application of ART in Saimiri spp. has been the lack of an effective gonadotropin preparation for ovarian stimulation. Pregnant mare serum gonadotropin (PMSG) is inexpensive and readily available, but its repeated use in rhesus monkeys has been associated with induction of a refractory state. We have compared PMSG to recombinant human follicle stimulating hormone (rhFSH) for controlled ovarian stimulation in Bolivian squirrel monkeys. Groups of mature squirrel monkeys received rhFSH (75 IU daily) or PMSG (250 IU twice daily) by subcutaneous injection for 4 d during the breeding season (November to January) or nonbreeding season (March to September). Serum estradiol (E2) was measured daily. Follicular growth was monitored by abdominal ultrasound. During the breeding season, PMSG induced a higher E2 response than did rhFSH, with mean E2 levels being significantly higher within 3 d of stimulation. Superior follicular development in PMSG animals was confirmed by abdominal ultrasonography. During the nonbreeding season, PMSG elicited a similar increase in serum E2 levels despite the fact that basal serum E2 is typically low during the nonbreeding season. Repeated use of PMSG (< or = 3 cycles of administration) produced no attenuation of the E2 response. We conclude that PMSG is highly effective for repeated cycles of controlled ovulation stimulation in the squirrel monkey.

    Deoxynivalenol (DON) is one of the most commonly occurring trichothecenes, produced mainly by Fusarium graminearum. Little is known about the effect of DON exposure or the levels of DON exposure that occur during pregnancy. The project aimed to provide data on levels of total DON and de-epoxi Deoxynivalenol (DOM-1) in pregnant human urine samples analysed by liquid chromatography-mass spectrometry (LC-MS). Morning urine samples were collected over two consecutive days from 42 volunteers and associated food consumption was recorded for the 24 h prior to the sample. Spearman’s rho non-parametric test for correlation was used to assess the data. Levels of DON did not differ significantly between day 1 (mean 29.7 ng/mL urine or 40.1 ng DON/mg creatinine) and day 2 (mean 28.7 ng/mL urine or 38.8 ng DON/mg creatinine ng/mL/day) urine samples. The only significant positive correlation was found between total ng DON/mg creatinine and parity (rho = 0.307, n = 42, p < 0.005 two-tailed) and total ng DON/mg creatinine with baked goods on day 1 (rho = 0.532, n = 42, p < 0.0005 two-tailed). This study provides data on the DON levels in pregnancy in this suburban population and reassurance that those levels are within acceptable limits. PMID:27792137

    Pneumocystis sp. is transmitted through the airborne route and presents a high host-species-specificity. Occasional reports of Pneumocystis pneumonia in still births and newborn infants suggest that other routes of transmission, e.g. transplacental might occur. The latter has been reported in rabbits but available data indicate that transplacental transmission of Pneumocystis seems not to occur in corticosteroid-treated rats and in SCID mice. The present study was undertaken to evaluate transplacental transmission of Pneumocystis oryctolagi. The spontaneously-acquired pneumocystosis rabbit model using hybrid California/New Zealand white female rabbits was selected because of similarities among rabbit and human placentas. Three different experiments were conducted in France and Chile. Pneumocystis organisms were detected by microscopy in the lungs of pregnant does and Pneumocystis DNA was found in the lungs of fetuses from the multiparous does from the second week to the end of gestation. Pneumocystis DNA was not detected in fetuses from primiparous does. Detection of Pneumocystis oryctolagi--DNA in fetuses of multiparous does and not in those of primiparous ones, suggests that transplacental transmission may be favored by multiple gestations. Whether Pneumocystis-DNA in fetal tissues from multiparous does resulted from transplacental passage of viable transmissible forms requires further investigation.

    Background: Cytomegalovirus (CMV) is the most frequent cause of congenital infection and commonly associated with sensorineural deficit. At present, there is neither prophylaxis nor treatment during pregnancy. The objective of this study was to evaluate the level of awareness regarding CMV infection and its consequences in women delivering at the University of Geneva Hospitals (Geneva, Switzerland). Methods: The study consisted of a validated questionnaire completed by women in the immediate postpartum period. Results: The questionnaire was completed by 59% (314/528) of delivering women. Only 39% (123/314) knew about CMV and 19.7% (62/314) had received information about preventive measures. Women were more aware about other congenital diseases, such as toxoplasmosis (87%); human immunodeficiency virus (99%); syphilis (85.5%); rubella (92.3%); and group B Streptococcus (63%). Factors associated with CMV awareness were Swiss nationality, high education level, employment in health care or with children, and being followed by an obstetrician. Regarding quality of information, few were aware of the main CMV complications (deafness, 25.2%; mental retardation, 34.5%). Among those informed about CMV, most (74.6%) knew about preventive measures. Among these, 82.5% thought that these were easily applicable. Conclusions: Most women are unaware of CMV infection and its potential risks during pregnancy. It is crucial to improve CMV information given to pregnant women to prevent the risks for the fetus/newborn. PMID:26633451

    Sterile inflammation and infection are key mediators of inflammation and peripheral insulin resistance associated with gestational diabetes mellitus (GDM). Studies have shown endoplasmic reticulum (ER) stress to induce inflammation and insulin resistance associated with obesity and type 2 diabetes, however is paucity of studies investigating the effects of ER stress in skeletal muscle on inflammation and insulin resistance associated with GDM. ER stress proteins IRE1α, GRP78 and XBP-1s were upregulated in skeletal muscle of obese pregnant women, whereas IRE1α was increased in GDM women. Suppression of ER stress, using ER stress inhibitor tauroursodeoxycholic acid (TUDCA) or siRNA knockdown of IRE1α and GRP78, significantly downregulated LPS-, poly(I:C)- or IL-1β-induced production of IL-6, IL-8, IL-1β and MCP-1. Furthermore, LPS-, poly(I:C)- or TNF-α-induced insulin resistance was improved following suppression of ER stress, by increasing insulin-stimulated phosphorylation of IR-β, IRS-1, GLUT-4 expression and glucose uptake. In summary, our inducible obesity and GDM-like models suggests that the development of GDM may be involved in activating ER stress-induced inflammation and insulin resistance in human skeletal muscle.

    ABSTRACT This preliminary report sought to provide insight into the genetic diversity of human immunodeficiency virus drug resistance (HIVDR) in Jamaica. This was done by investigating the genetic diversity associated with drug resistance in pregnant women living with HIV attending antenatal clinics in Kingston, Jamaica. Blood samples were collected and viral RNA were extracted and analysed. The protease and reverse transcriptase (Pro-RT) genes were amplified using the nested polymerase chain reaction (PCR) method. Polymerase chain reaction amplicons were obtained for nine (56%) of 16 patients, of which five (55%) were antiretroviral (ARV) drug naïve and four (45%) were treatment experienced. Three minor protease inhibitor resistant-conferring mutations (A71AT, A71V, A71T) and five mutations conferring high to low-level resistance (K219EK, T69S, K103S, G190A and K103N) were detected in the RT region. More than 50% of the resistance mutations found were detected in ARV drug naïve individuals, implying that viruses are being transmitted with the ARV resistance. These preliminary results will inform the health practitioners of the level of drug resistance that is being transmitted as well as strengthen the need to initiate a national baseline survey on HIVDR in Jamaica.

    Background Zika virus (ZIKV) has been linked to central nervous system malformations in fetuses. To characterize the spectrum of ZIKV disease in pregnant women and infants, we followed patients in Rio de Janeiro to describe clinical manifestations in mothers and repercussions of acute ZIKV infection in infants. Methods We enrolled pregnant women in whom a rash had developed within the previous 5 days and tested blood and urine specimens for ZIKV by reverse-transcriptase-polymerase-chain-reaction assays. We followed women prospectively to obtain data on pregnancy and infant outcomes. Results A total of 345 women were enrolled from September 2015 through May 2016; of these, 182 women (53%) tested positive for ZIKV in blood, urine, or both. The timing of acute ZIKV infection ranged from 6 to 39 weeks of gestation. Predominant maternal clinical features included a pruritic descending macular or maculopapular rash, arthralgias, conjunctival injection, and headache; 27% had fever (short-term and low-grade). By July 2016, a total of 134 ZIKV-affected pregnancies and 73 ZIKV-unaffected pregnancies had reached completion, with outcomes known for 125 ZIKV-affected and 61 ZIKV-unaffected pregnancies. Infection with chikungunya virus was identified in 42% of women without ZIKV infection versus 3% of women with ZIKV infection (P<0.001). Rates of fetal death were 7% in both groups; overall adverse outcomes were 46% among offspring of ZIKV-positive women versus 11.5% among offspring of ZIKV-negative women (P<0.001). Among 117 live infants born to 116 ZIKV-positive women, 42% were found to have grossly abnormal clinical or brain imaging findings or both, including 4 infants with microcephaly. Adverse outcomes were noted regardless of the trimester during which the women were infected with ZIKV (55% of pregnancies had adverse outcomes after maternal infection in the first trimester, 52% after infection in the second trimester, and 29% after infection in the third trimester

    Oxidative stress is considered to be the main cause of diabetic complications. In the current study, we investigated the effect of selenium-vitamin E combination and melatonin on lipid peroxidation (LPO) and scavenging enzyme activity in the blood of streptozocin (STZ)-induced diabetic pregnant rats. Forty female Wistar rats were randomly divided into five groups. The first and second groups were used as the non-pregnant control and pregnant control groups, respectively. The third group was the pregnant diabetic group. Vitamin E plus selenium and melatonin were administered to the diabetic pregnant rats consisting fourth and fifth groups, respectively. Diabetes was induced on day 0 of the study by STZ. Blood samples were taken from all animals on the 20th day of pregnancy. LPO level was higher in diabetic pregnant rats than in control, although superoxide dismutase, catalase, and glutathione peroxidase activities were lower in diabetic pregnant animals than in control. LPO levels were lower both in the two treatment groups than in the diabetic pregnant rats, whereas selenium-vitamin E combination and melatonin caused a significant increase in the activities of these antioxidant enzymes (p<0.01). In conclusion, vitamin E plus selenium seems to be a more potent antioxidant compared to melatonin in diabetic pregnant rats. Melatonin did not significantly affect the elevated glucose concentration of diabetic pregnant treated with melatonin group. Vitamin E plus selenium may play a role in preventing diabetes-related diseases of pregnant subjects.

    Zearalenone (ZEN) is an oestrogenic mycotoxin commonly found in food and feed products and can affect reproduction and development in both humans and animals. This study aimed to determine the toxic effects of ZEN on maternal SD rats and the F1 female offspring. Sixty-four pregnant rats were divided into 4 groups and exposed to feed contaminated with ZEN (0, 5, 10, and 20 mg/kg feed) on gestational days (GDs) 0–21. Compared with the controls, the groups exposed to 10 and 20 mg/kg ZEN showed significantly decreased feed intake and body weight of pregnant rats and/or female offspring. Meanwhile, 20 mg/kg ZEN significantly decreased the birth weight and viability of F1 newborn rats. Moreover, 10 and 20 mg/kg ZEN diets increased follicle-stimulating hormone concentrations but decreased oestradiol in both maternal and F1 adult rats. In the F1 generation, ZEN caused no pathological changes in ovaries and uterus in weaned rats, but significant follicular atresia and a thinning uterine layer were found in F1 female adult rats in the 20 mg/kg ZEN group. These impairments concurred with the inhibited mRNA and protein levels of oestrogen receptor-alpha (Esr1) and 3β-hydroxysteroid dehydrogenase (HSD) in the adult uterus and/or ovaries. Furthermore, 10 and/or 20 mg/kg ZEN exposure significantly reduced Esr1, gonadotropin-releasing hormone receptor (GnRHr), and ATP binding cassette transporters b1 and c1 (ABCb1 and ABCc1) in the placenta and foetal and weaned F1 brains, and also produced a dose-dependent increase in 3β-HSD in the placenta. Additionally, 20 mg/kg ZEN significantly upregulated ABCc5 expression in the placenta and ovaries of weaned rats. These results suggested that prenatal ZEN exposure in rats affected maternal and foetal development and may lead to long-term reproductive impairment in F1 adult females. PMID:28067781

    OBJECTIVE Uterine overdistention is thought to induce preterm labor in women with twin and multiple pregnancies, but the pathophysiology remains unclear. We investigated for the first time the pathogenesis of preterm birth associated with rapid uterine distention in a pregnant nonhuman primate model. STUDY DESIGN A nonhuman primate model of uterine overdistention was created using preterm chronically catheterized pregnant pigtail macaques (Macaca nemestrina) by inflation of intraamniotic balloons (N = 6), which were compared to saline controls (N = 5). Cesarean delivery was performed due to preterm labor or at experimental end. Microarray, quantitative reverse transcriptase polymerase chain reaction, Luminex (Austin, TX), and enzyme-linked immunosorbent assay were used to measure messenger RNA (mRNA) and/or protein levels from monkey (amniotic fluid, myometrium, maternal plasma) and human (amniocytes, amnion, myometrium) tissues. Statistical analysis employed analysis of covariance and Wilcoxon rank sum. Biomechanical forces were calculated using the law of Laplace. RESULTS Preterm labor occurred in 3 of 6 animals after balloon inflation and correlated with greater balloon volume and uterine wall stress. Significant elevations of inflammatory cytokines and prostaglandins occurred following uterine overdistention in an “inflammatory pulse” that correlated with preterm labor (interleukin [IL]-1β, tumor necrosis factor [TNF]-α, IL-6, IL-8, CCL2, prostaglandin E2, prostaglandin F2α, all P < .05). A similar inflammatory response was observed in amniocytes in vitro following mechanical stretch (IL1β, IL6, and IL8 mRNA multiple time points, P < .05), in amnion of women with polyhydramnios (IL6 and TNF mRNA, P < .05) and in amnion (TNF-α) and myometrium of women with twins in early labor (IL6, IL8, CCL2, all P < .05). Genes differentially expressed in the nonhuman primate after balloon inflation and in women with polyhydramnios and twins are involved in tissue

    Companion animals play an important role in our society. However, pregnant women and new mothers might have specific concerns about animal-associated health outcomes because of their altered immune function and posture as well as their newborn babies. The study was conducted to collect baseline data for developing an evidence-based intervention for pregnant women and new mothers to help them adopt certain behaviors to prevent adverse animal-associated health outcomes. A survey, using the Health Belief Model as the theoretical framework, was developed and administered to 326 women attending the Women, Infants, and Children programs in Illinois and Indiana in 2015. Prevalence of dog and cat ownership was estimated to be 39% (95% CI: 33–45%) and 26% (95% CI: 21–31%), respectively. Regardless of pet ownership, 74% of the respondents reported having some type of animal contact in the past month. Pregnancy or the birth of a child altered some animal contact practices among the study participants; particularly a discontinuation or decrease in cleaning cat litter boxes. Reports of diseases contracted from animals were low (4%) in this study. By contrast, animal-associated injuries were prevalent (42%), and the majority were caused by animals the respondents owned (56%). Overall, respondents indicated that they appreciated the benefits of a program addressing animal-associated health outcomes and did not indicate strong resistance to adopt certain behaviors. The majority recognized human health-care providers as a source of information about animal contact and associated health outcomes but less frequently identified veterinarians as a source for such information. In addition, although most of the respondents felt that health-care providers and veterinarians should initiate discussions about preventing animal-associated illness and injuries, only 41% among those who had visited doctors or prenatal care services reported that their health-care providers discussed these

    The highly pathogenic avian influenza H5N1 virus is one of candidates for future pandemic. Since H5N1 viruses had previously been isolated only from avian species, the outbreak raised questions about the ability of these viruses to cause severe disease and death in humans. Pregnant women are at increased risk for influenza-associated illness and death. However, little is known about whether influenza viruses could transmit to the fetus through the placenta, and the effects of abortion and preterm delivery to maternal influenza infection are not well understood. We found that the H5N1 viruses could vertical transmit to the fetus through the placenta in the BALB/c mouse model, and the viruses could partly be evacuated by the pregnant mice during abortion or preterm delivery. This study may further our understanding about the transmission of this highly pathogenic avian influenza viruses, supply optimized clinical treatment method for pregnant women, and shed some light on better preventing and controlling for future potential outbreak of H5N1 influenza pandemic.

    Objective To describe Group B Streptococcus (GBS) prevention policies at 12 Latin American sites participating in the NICHD (Eunice Kennedy Shriver National Institute of Child Health and Human Development) International Site Development Initiative (NISDI) Longitudinal Study in Latin American Countries (LILAC) and to determine rates of rectovaginal colonization and GBS-related disease among HIV-infected pregnant women and their infants. Methods Site surveys were used to assess prevention policies and practices administered cross-sectionally during 2010. Data collected in NISDI from 2008 to 2010 regarding HIV-infected pregnant women were used to determine rates of colonization and GBS-related disease. Results Of the 9 sites with a GBS prevention policy, 7 performed routine rectovaginal screening for GBS. Of the 401 women included in the NISDI study, 56.9% were at sites that screened. The GBS colonization rate was 8.3% (19/228 women; 95% confidence interval [CI], 5.1%–12.7%). Disease related to GBS occurred in 0.5% of the participants (2/401 women; 95% CI, 0.1%–1.8%); however, no GBS-related disease was reported among the 398 infants (95% CI, 0.0%–0.9%). Conclusion Improved efforts to implement prevention policies and continued surveillance for GBS are needed to understand the impact of GBS among HIV-infected pregnant women and their infants in Latin America.

    2001-08-08

    Sick leave rates among pregnant women have been found to vary substantially over time. 8,884 woman delivered at Linköping and Värnamo Women's Clinics in 1978, 1986, 1988, 1992, 1995 and 1997 were studied. Sick leave nearly doubled between 1978 and 1986, and dropped back to the 1978 level in 1997. The somewhat paradoxical findings in our surveys indicate that attitudes, especially as observed in the youngest age groups, together with a sensible adaptation to the prevailing terms of the social security system, may well be the most plausible explanation. Studies on sick leave among women of fertile age should preferably also contain information on the proportion of sick-listed pregnant women, as a small proportion of pregnant women may have a profound impact on sick leave statistics among all insured women of fertile age.

    2016-01-01

    The left atrium is the most common location of myxomas, which are benign tumors. Only a few cases of myxomas in pregnancies have been reported. Our thorough medical literature search showed only 17 reported cases in the course of pregnancy. Myxomas during pregnancy and in the preterm period constitute a serious phenomenon that can mimic an early sign of a life-threatening pathology like severe mitral stenosis. We describe a 33-year-old woman, who presented with acute dyspnea to a gynecology center and was referred to our hospital for further evaluation of pulmonary embolism. Transthoracic echocardiography showed a huge left atrial myxoma, and computed tomography scan illustrated paradoxical pulmonary embolism in the left upper lung lobe via a large patent foramen ovale. The tumor required urgent cardiac surgery. In this article, we review causes of dyspnea in pregnancy and the cardiovascular effects of myxomas in pregnancy. We also describe the pathophysiological effects of cardiopulmonary bypass on the mother, fetus, and the feto-placental system during open-heart surgery. We performed a successful surgical resection of a myxoma in a pregnant woman. Given the rarity of such cases, individual multidisciplinary assessment and management strategies are essential.

    Intimate partner violence (IPV) during pregnancy is a major public health issue with significant implications for maternal mental health. Less studied is the association between IPV during pregnancy and suicidal ideation. This study reports the prevalence and correlates of suicidal ideation among low-income pregnant women receiving prenatal care at a university obstetrical clinic from February 2009 to March 2010. We performed a cross-sectional analysis of 166 women surveyed between 24 and 28 weeks of gestation using the Edinburgh Postnatal Depression Scale (EPDS) and the Abuse Assessment Screen (AAS). Multiple logistic regression identified factors associated with antenatal suicidal ideation. The prevalence of suicidal ideation was 22.89 %. In the fully adjusted model, antenatal depressive symptomatology (OR = 17.04; 95 % CI 2.10-38.27) and experiencing IPV (OR = 9.37; 95 % CI 3.41-25.75) were significantly associated with an increased risk of antenatal suicidal ideation. The prevalence of antenatal suicidal ideation in the current study was higher than other population-based samples though this sample was predominantly single, low-income, and 19 % experienced IPV during pregnancy. Given the strong association of antenatal suicidal ideation, depressive symptomatology, and IPV, health care providers are urged to identify those women at risk so that antenatal care can be tailored to best support optimal maternal and neonatal outcomes.

    Pregnant and breastfeeding women who eat vegetarian are a source of much controversy. This is the result of concern that eliminating some or all animal produce may lead to nutritional deficiencies and thus adversely affect the mother's and child's health. The American Dietetic Association's position is that appropriately planned vegan, lacto-vegetarian and lacto-ovo-vegetarian diets ensure a normal course of pregnancy and lactation. However, in practice the balancing of such a diet can pose certain difficulties, especially for individuals without the necessary experience or knowledge about nutrition. Nutrients to which particular attention needs to be paid to ensure their sufficient supply include: protein (essential amino acids), Omega-3 essential fatty acids, iron and calcium as well as vitamins D and B(12). The proper adherence to recommendations can be attained with a varied diet containing suitable plant products compensating for the nutritional value of the eliminated animal products. Supplementation with vitamin D and vitamin B(12) is also necessary. Research shows that infants born to vegetarian mothers are born at term and have normal birth weight. There is an increased risk of hypospadias in boys. The main difference in the composition of vegetarian mothers' milk compared to non-vegetarians' is lower content of docosahexaenoic acid and higher content of Linoleic and α-Linolenic acid.

    Deficiencies in calcium (Ca) and magnesium (Mg) are associated with various complications during pregnancy. To test the hypothesis that the status of these minerals is inadequate in pregnancy, a cross-sectional study was conducted of the dietary intake and status of Ca and Mg in pregnant women (n = 50) attending a general public university hospital in Brazil. Dietary intake was assessed from 4-day food records; levels of plasma Mg, erythrocyte Mg, and urinary Ca and Mg excretion were determined by flame atomic absorption spectroscopy; and type I collagen C-telopeptides were evaluated by enzyme-linked immunosorbent assay. Probabilities of inadequate Ca and Mg intake were exhibited by 58 and 98% of the study population, respectively. The mean levels of urinary Ca and Mg excretion were 8.55 and 3.77 mmol/L, respectively. Plasma C-telopeptides, plasma Mg, and erythrocyte Mg were within normal levels. Multiple linear regression analysis revealed positive relationships among urinary Ca excretion, Ca intake (P = .002) and urinary Mg excretion (P < .001) and between erythrocyte Mg and Mg intake (P = .023). It is concluded that the Ca and Mg status of participants was adequate even though the intake of Ca and Mg was lower than the recommended level.

    This research aimed to develop an initial understanding of the stressors, stress responses, and personal resources that impact African American women during pregnancy, potentially leading to preterm birth. Guided by the ecological model, a prospective, mixed-methods, complementarity design was used with 11 pregnant women and 8 of their significant others. Our integrated analysis of quantitative and qualitative data revealed 2 types of stress responses: high stress responses (7 women) and low stress responses (4 women). Patterns of stress responses were seen in psychological stress and cervical remodeling (attenuation or cervical length). All women in the high stress responses group had high depression and/or low psychological well-being and abnormal cervical remodeling at one or both data collection times. All but 1 woman had at least 3 sources of stress (racial, neighborhood, financial, or network). In contrast, 3 of the 4 women in the low stress responses group had only 2 sources of stress (racial, neighborhood, financial, or network) and 1 had none; these women also reported higher perceived support. The findings demonstrate the importance of periodically assessing stress in African American women during pregnancy, particularly related to their support network as well as the positive supports they receive.

    The effect of restricting placental growth on glucose metabolism in pregnant sheep in late gestation was determined by primed constant infusions of D-(U-{sup 14}C)- and D-(2-{sup 3}H)glucose and antipyrine into fetuses of six control sheep and six sheep from which endometrial caruncles had been removed before pregnancy (caruncle sheep). In the latter, placental and fetal weights were reduced, as was the concentration of glucose in fetal arterial blood. Fetal glucose turnover in caruncle sheep was only 52-59% of that in controls, largely because of lower umbilical loss of glucose back to the placenta (38-39% of control) and lower fetal glucose utilization (61-74% of control). However, fetal glucose utilization on a weight-specific basis was similar in control and caruncle sheep. Significant endogenous glucose production occurred in control and caruncle fetal sheep. Maternal glucose production and partition of glucose between the gravid uterus and other maternal tissues were similar in control and caruncle sheep. In conclusion, when placental and fetal growth are restricted, fetal glucose utilization is maintained by reduced loss of glucose back to the placenta and mother and by maintaining endogenous glucose production.

    The administration of the polyaromatic compounds {beta}-naphthoflavone ({beta}NF) and 3-methylcholanthrene (3MC) to pregnant rats during mid-gestation has been shown to produce marked feto-placental growth retardation. This study examined secretory protein synthesis in placental tissue from rats following administration of {beta}NF on gestation days (gd) 11-14 or 3MC on gd 12-14. Explants of placental basal zone tissue were cultured for 24 hours in serum-free medium in the presence of ({sup 3}H)leucine. Secreted proteins were analyzed by two-dimensional SDS-polyacrylamide gel electrophoresis followed by either fluorography or immunostaining. Total incorporation of ({sup 3}H)leucine into secreted proteins was not altered in BZ explants from {beta}NF or 3MC-treated animals. However a selective decrease was observed in ({sup 3}H)leucine incorporation into a major complex of proteins with apparent molecular weight of 25-30,000 and isoelectric point between 5.3 to 5.7. This group of proteins has been further identified as being related to rat pituitary growth hormone (GH) using N-terminal amino acid microsequencing of individual spots from 2-D SDS-PA gels. This is the first report that synthesis of GH-related proteins by rat placenta is decreased following {beta}NF and 3MC administration, a change which may underlie the feto-placental growth retardation associated with these polyaromatic compounds.

    A cross-sectional study was conducted between August and September 2010 at the antenatal care clinic of the Araba Waeshreen Hospital (Geizera), central Sudan. Sociodemographic, medical, obstetric and use of pica information were gathered. Body mass index (BMI) was calculated. Haemoglobin levels were measured and blood films and stools were examined for malaria and schistosomiasis. Out of the 292 women, 119 (40.8%) had anaemia (HB < 11 g/dl); eight (2.7%) had severe anaemia (HB < 7 g/dl). One patient had a positive blood film for malaria. A total of 38 (13.0%) out of the 292 pregnant women had S. mansoni infections. While age, parity, gestational age, education, occupation, interpregnancy interval and BMI were not associated with anaemia, pica (OR = 1.7, 95% CI = 1.0-2.9, p = 0.02) and S. mansoni infections (OR = 2.8, 95% CI = 1.2-6.7, p = 0.01) were significantly associated with anaemia using univariate and multivariate analyses. The high prevalence of anaemia among these women needs to be controlled through preventive measurement of S. mansoni infections and health education to prevent practising pica.

    Growth curve models were conducted on assessments of family functioning at four time points from the third-trimester of pregnancy through the first year postpartum for 96 Latino families in which an adolescent daughter was pregnant. Results indicated significant family-level change following an adolescent's childbearing, though there were notable differences between family members in their perceptions of family functioning. Family conflict, as perceived by parenting teens, increased in the latter half of the first year after an initial decline, and family companionship (as rated by mothers and siblings) decreased. Parenting adolescents and siblings perceived significant increases in family cohesion, whereas mothers perceived a significant decline. Unplanned pregnancies, family financial hardship, and expected stress predicted unfavorable family functioning at 1 year. Contrary to expectations, adolescents' greater prenatal efforts to prepare for parenting predicted subsequent family conflict and declines in family cohesion (particularly as rated by mothers). Family members' acculturation level and attitudes of familism, gender roles, and the status attained by parenthood also had predictive effects. Implications of study findings for family adjustment following an adolescent's childbearing are discussed.

    One hundred and sixty-five pregnant Nigerian women attending the antenatal clinic of LAUTECH teaching hospital, Ogbomoso, Nigeria between January and April 2014 were interviewed using a structured questionnaire. Socio-demographic characteristics of the respondents were obtained. Respondents were also asked: if they had had their eye examined by an eye specialist during the index pregnancy, frequencies of visit to eye care centers and indications for their visitation. A history of previous eye examination by eye care specialist/visit to eye clinic was considered as eye care utilisation. Selection of eligible subjects who consented to participate in the study was done using simple random technique. Logistic regression model was used to control sociodemographic and obstetric factors in order to determine independent covariate factor influencing the use of eye care services. Among the population studied, only 46 (32%) had eye examination during the index pregnancy. Level of education and occupational status of the respondents were found to be statistically significant factors (p = 0.001 and 0.008, respectively). There is a need for a policy that will encourage regular eye care services usage during pregnancy.

    Four groups of 12 pregnant Wistar rats each were fed with rations containing 0, 0.01, 0.015 and 0.02% of monocrotaline (MCT) from day 6 to 21 of gestation. Liver weights of the dams from the three experimental groups were significantly lower than those from the control group. Serum levels of aspartate aminotransferase; alkaline phosphatase; lactate dehydrogenase; gamma glutamyltransferase, urea and creatinine were significantly higher in dams from MCT 0.02% group. The weights of the placenta, fetuses and fetal lungs of the 0.02% MCT group were significantly lower than those of the control group. A mild to moderate interstitial pneumonia and liver lesions were observed in dams ingesting 0.02% of MCT. These results showed the toxicity of MCT to the females that ingested 0.02% and their fetuses. Because there was no differences on the weight gains and food and water consumption of the dams it is suggested that this toxic effects in the fetuses was caused by the diffusion of MCT through the placenta. No significant differences were observed in the frequency of skeletal and visceral malformation or anomalies between the control and treated groups suggesting that MCT had no teratogenic effect.

    This study set out to (1) estimate the prevalence of three forms of feeding intention among 2,178 pregnant women in six of Hong Kong's regional hospitals and (2) identify the associated demographic, socioeconomic, obstetric and relational correlates. The research design was exploratory, cross-sectional, and quantitative. The Chinese version of a self-administered questionnaire was used to collect the demographic, socio-economic, and obstetric characteristics of the women. Couples' relationships were investigated using the Dyadic Adjustment Scale. All women in the second trimester of their pregnancies who attended the target antenatal clinics within the data collection period of December 2004 to December 2006 were recruited. The prevalence rates of breastfeeding, mixed feeding and artificial feeding were 53.9%, 14.8%, and 31.3%, respectively. Women who had been born in Hong Kong, lived in accommodation that was > or = 300 feet(2) (approximately 30 m(2)), had made an early antenatal booking, had a planned pregnancy, were experiencing their first pregnancy, and had a lower level of conflict with their partners were significantly more likely to opt for breastfeeding. Women who had been born in Hong Kong and already had children were significantly more likely to choose mixed feeding, compared with the artificial group in a multinomial logistic regression model. These findings suggest that effective promotion of breastfeeding during the prenatal period must target the correlates of feeding intention.

    The toxic effects of cadmium on the thyroid gland of pregnant rats were studied with an electron microscope and an X-ray microanalyzer. Serum levels of thyroid hormones (T3 and T4) were also analyzed. Deterioration of the rough-surfaced endoplasmic reticulum occurred in the thyroid follicular epithelium on the fifth day of cadmium treatment. Large intracellular vacuoles, which arose from dilated cisternae of the rough-surfaced endoplasmic reticulum, were fused together, and marked swelling of the mitochondria was also noted. Thyroglobulin-secreting granules at the apical cytoplasm were decreased in number. By energy dispersive X-ray microanalysis, cadmium peaks were preferentially obtained from swollen mitochondria in the follicular epithelial cells. Serum levels of T3 and T4 were significantly decreased in cadmium-treated rats dams when compared to those of controls. In the present experiment, cycloheximide also caused degenerative changes in the rough-surfaced endoplasmic reticulum and the disappearance of thyroglobulin-secreting granules. Cycloheximide is a known inhibitor of protein synthesis on cytosolic ribosomes. These results indicated that accumulated cadmium in the mitochondria of thyroid follicular epithelial cells might disturb the oxidative phosphorylation of this organelle and the loss of energy supply possibly caused the inhibition of the synthesis and release of thyroid hormones.

    Objective The quality and duration of sleep is impaired during pregnancy. Our study aimed to determine whether maternal sleep deprivation occurring during the second and third trimester of pregnancy could alter fetal well-being with respect to birth weight and APGAR score by altering the inflammatory status and oxidative stress in the mothers.  Methods Sleep adequacy was assessed using the Pittsburgh Sleep Quality Index (PSQI). We investigated the inflammatory status and oxidative stress at term in the blood of pregnant subjects with and without sleep deprivation by measuring the levels of protein-bound sialic acid (PBSA), high-sensitivity C-reactive protein (hsCRP), malondialdehyde (MDA) and protein carbonyl (PCO). Homocysteine (Hcy) and its vitamin determinants were also measured. Fetal outcome with respect to birth weight and APGAR score were compared between study subjects.  Results A significant increase was observed in the levels of hsCRP, PBSA, Hcy, MDA, and PCO, in the sleep-deprived group when compared to the control group. Fetal outcome at birth showed a significant difference between the cases with high sleep deprivation and those with low sleep deprivation.  Conclusion Sleep deprivation in pregnancy leads to an increase in the inflammatory parameters, oxidative stress, and Hcy levels. Fetal outcome at birth was affected more in mothers with high sleep deprivation than those with low sleep deprivation. Follow-up in these babies are needed to reveal any differences in their growth and development. PMID:26366260

    The effects of spaceflight on mammary metabolism of 10 pregnant rats was measured on Day 20 of pregnancy and after parturition. Rats were flown on the space shuttle from Day 11 through Day 20 of pregnancy. After their return to earth, glucose oxidation to carbon dioxide increased 43% (P < 0.05), and incorporation into fatty acids increased 300% (P < 0.005) compared to controls. It is unclear whether the enhanced glucose use is due to spaceflight or a response to landing. Casein mRNA and gross histology were not altered at Day 20 of pregnancy. Six rats gave birth (on Day 22 to 23 of pregnancy) and mammary metabolic activity was measured immediately postpartum. The earlier effects of spaceflight were no longer apparent. There was also no difference in expression of beta-casein mRNA. It is clear from these studies that spaceflight does not impair the normal development of the mammary gland, its ability to use glucose, nor the ability to express mRNA for a major milk protein.

    Understanding concerns about the welfare of farm animals is important for the development of socially sustainable production practices. This study used an online survey to test how views on group versus stall housing for pregnant sows varied when Canadian and US participants were provided information about these systems, including access to scientific papers, YouTube videos, Google images, and a frequently-asked-questions page (S1 Appendix). Initial responses and changes in responses after accessing the information were analyzed from Likert scores of 242 participants and from their written comments. Participants were less willing to accept the use of gestation stalls after viewing information on sow housing. For example, initially 30.4% of respondents indicated that they supported the use of gestation stalls; this declined to 17.8% after participants were provided additional information. Qualitative analysis of comments showed that supporters of gestation stalls expressed concern about the spread of disease and aggression between animals in less confined systems, whereas supporters of group housing placed more emphasis on the sow’s ability to interact socially and perform natural behaviors. These results point to public opposition to the use of gestation stalls, and indicate that the more that the public learns about gestation stalls the less willing they will be to accept their use.

    The aims of this literature review are: to depict the main oral diseases that are related to pregnancy; to clarify some of the possible systemic mechanisms that are associated with these changes; and to address issues about oral care during pregnancy. A woman's organs undergo various physiological, neurological, and hormonal changes during pregnancy. Such changes occur gradually and are essential for the development of the fetus, providing what is needed for tissue formation and establishment of reserves for uterine and fetal life. In turn, the oral cavity shows some events during this period. Among the changes most frequently cited in the literature are pyogenic granuloma, gingivitis, and periodontitis. The inflammation of the periodontal tissues due to the formation of the biofilm increases dramatically in size and severity during the course of a normal pregnancy, even without changes in the amount of biofilm present. In addition, a decrease in salivary pH is observed in pregnant women and may lead to an increased incidence of dental caries in this period.

    Food intake of rats increases during pregnancy. This requires changes in the structure of the small intestine to absorb additional food. The aim of the present study was to investigate the morphological changes in the layers of small intestine in rats during pregnancy. Duodenum, jejunum and ileum of 18 pregnant Sprague-Dawley rats (day 7, 14 and 21 of pregnancy) were collected. Villous height and width and thickness of lamina propria, tunica muscularis entirely and separately (circular and longitudinal layers) were measured on transverse sections. During pregnancy increasing villi length and muscular layer thickness was observed in duodenum. Furthermore, along with the progress of gestation greatest histomorphometric change in small intestine was observed in the jejunum. The reduction in the ileum histomorphologic indices was observed during pregnancy. In conclusion, increase in histomorphologic indices of duodenum and jejunum supplies more capacity of duodenum to digest food intake during pregnancy and decrease in these indices in ileum controls the absorption of excess produced amino acids and glucose by hyperphagia.

Methods After IRB approval, an EMERSE search was used to identify all women treated at the University of Michigan from 1998–2010 with head and neck squamous cell carcinoma (HNSCC) during pregnancy. This identified four patients with tongue cancer. Biomarkers and HPV were assessed by immunohistochemistry and multiplex PCR/Mass spectrometry, respectively. Results Two patients responded well to therapy and are alive more than 10 years after diagnosis; two died of disease. All tumors overexpressed EGFR and Bcl-xL, three of four overexpressed c-Met, both tumors that progressed overexpressed p53. All tumors were negative for HPV, p16, ER, PR, and HER-2. Conclusions Biomarkers of aggressive tumors (high EGFR, Bcl-xL, c-Met; low p53) did not correlate with outcome. Additional studies are needed to determine whether perineural invasion, delay in diagnosis, and p53 overexpression are factors related to poorer survival. PMID:22422571

    The purpose of this research is to study the fetal head circumference (HC) biometry for local population. Retrospective study was selected, done at Hospital Pulau Pinang and 5551 files of pregnant women were collected. The HC mean values of this study (HCmean) was compared with other published studies to see whether there was any difference between the various populations in the world. Comparison of means, regression analysis and paired sample t-test in SPSS software version 11.5 were used in the analysis. A total of 9874 HC data (mm) were recorded for gestational age (GA) of 12 to 41 weeks. The HC growth rate in second trimester (11.32 mm/week) has decreased to nearly half than in third trimester (5.53 mm/week). The HCmean was found to be highly significant difference (SD) than other 9 studies and only lower than HC values of USA, UK and Zimbabwe populations. The HC values of German show close similarity with HCmean. From 45 comparisons done, more than three-quarter of the comparisons resulted as SD (37) compared to insignificant differences (8). Consequently, each country should have their own standard HC of fetus biometry of the various gestations for their own population.

    Peganum harmala L. is a plant widely distributed in the Mediterranean region. It is commonly used in traditional medicine in Morocco as sedative and abortifacient but exposes users to the risk of overdose and poisoning. The pharmacologically active compounds of this plant include a number of β -carboline and quinazoline alkaloids responsible of its pharmacological and toxicological effects. We report the case of a 24-year-old woman, 22 weeks pregnant, intoxicated with the seeds of Peganum harmala L. On admission, she had disturbance of consciousness, uterine contraction, and oliguria. Laboratory tests revealed renal failure and liver injury, and she benefited then from hemodialysis. During hospitalization, she was intubated after deterioration of consciousness and presented a spontaneous expulsion of the fetus. After extubation, she kept unusual sequelae: cerebellar ataxia and peripheral polyneuropathy. Physicians in regions using Peganum harmala L. as traditional medicine must be able to detect symptoms of its toxicity, in order to establish early gastrointestinal decontamination. The prognosis of this intoxication is variable; most cases can be managed successfully; but in high doses of intoxication, evolution can be fatal.

    2013-01-01

    Background Malaria and Soil Transmitted Helminthiasis (STH) are co-endemic and major public health problems in Ethiopia. The aim of the study was to assess the prevalence of malaria and STHs co-infection and to determine the association risk factors. Methods A cross-sectional community based study was conducted on 388 pregnant women living in three districts around Gilgel Gibe Dam area, southwestern Ethiopia. Socio-demographic and socio-economic data, single stool sample and blood sample were collected from each participant. Results The prevalence of STH and malaria was 159 (41%) and 45 (11.6%), respectively and the prevalence of STHs/malaria co-infection was 30 (7.7%). Hookworm was the most prevalent 114 (29.4%) soil transmitted helminthiasis infection followed by Ascaris lumbricoides (A. lumbricoides) 58 (15%) and Trichuris trichiura (T. trichiura) 13 (3.4%). Habit of eating soil (Adjusted Odds Ratio (AOR) = 4.64, 95% CI: 1.50-14.36, P=0.008), presence of stagnant water near study participants’ house (AOR=2.99, 95% CI: 1.28-6.99, P=0.012) and habit of using human feces as a fertilizer (AOR= 5.34, 95% CI: 1.99-14.28, P<0.001) were found to be significantly associated with malaria and STH co-infection among the pregnant women. Hookworm parasitic load was positively correlated with malaria parasitic load (r = 0.299, P<0.001) while A. lumbricoides parasitic load was negatively correlated with malaria parasitic load (r = −0.095, P<0.001). Conclusion Intestinal parasite and/or malaria co-infection is a health problem among pregnant women living around Gilgel Gibe dam area. Therefore, intervention including improving sanitation, removing stagnant water, and health education to the pregnant women should be given. PMID:23837685

    BACKGROUND Acute pulmonary edema in a pregnant patient is associated with significant morbidity and mortality. Takotsubo syndrome, or stress-induced cardiomyopathy, is a rare cause of acute pulmonary edema in a pregnant patient, especially prior to delivery of the fetus. CASE REPORT We describe a case of a pregnant patient who presented with acute pulmonary edema and eclampsia and was found to have Takotsubo syndrome. To the best of our knowledge, eclampsia as a precipitating factor for Takotsubo syndrome has not been described in literature. CONCLUSIONS Clinicians taking care of pregnant patients should be aware of the potential link between eclampsia and Takotsubo cardiomyopathy. Prompt correction of the precipitating cause along with supportive management as described is the key to a successful outcome.

    Feelings of romanticism and self-esteem among pregnant adolescents, adolescent mothers, and a control group of nonpregnant, nonparenting adolescents were investigated. The Bachman Self-Esteem Scale (Bachman, O'Malley, & Johnston, 1978) and the Dean Romanticism Scale (Dean, 1961) were distributed to 649 U.S. female adolescents--255 pregnant adolescents, 121 adolescent mothers, and 273 teenagers in the control group. For romanticism, the results indicated a significant main effect for group (pregnant teens, teen mothers, and a control group consisting of nonpregnant, nonparenting teenagers) and ethnicity (White, Hispanic, African American, and Asian) but not for age (13 to 15 years and 16 to 19 years). The pregnant teens and teen mothers thus had a higher degree of romanticism than the control group did. For self-esteem, there was a significant main effect for race, but not for group or for age. This main effect was qualified by a significant interaction between ethnicity and age.

    Though much progress has been made on inclusion of non-pregnant women in research, thoughtful discussion about including pregnant women has lagged behind. We outline resulting knowledge gaps and their costs and then highlight four reasons why ethically we are obliged to confront the challenges of including pregnant women in clinical research. These are: the need for effective treatment for women during pregnancy, fetal safety, harm from the reticence to prescribe potentially beneficial medication, and the broader issues of justice and access to benefits of research participation. Going forward requires shifting the burden of justification from inclusion to exclusion and developing an adequate ethical framework that specifies suitable justifications for excluding pregnant women from research.

    ABSTRACT Maternal immunization has the potential to reduce the burden of infectious diseases in the pregnant woman and her infant. Many countries now recommend immunization against influenza at any stage of pregnancy and against pertussis in the third trimester. Despite evidence of the safety and effectiveness of these vaccines when administered during pregnancy, uptake generally remains low for influenza and moderate for pertussis vaccine. Enhancing confidence in both immunization providers and pregnant women by increasing the evidence-base for the safety and effectiveness of vaccines during pregnancy, improving communication and access by incorporating immunization into standard models of antenatal care are likely to improve uptake. Developing a framework for implementation of vaccines for pregnant women which is cognizant of local and national cultural, epidemiological, behavioral and societal factors will enable a smooth transition and high uptake for new vaccines currently in development for pregnant women.

    We studied the effect of active cytomegalovirus infection on histidine content in peripheral blood erythrocytes of pregnant women at gestation weeks 20-22 and its involvement into hemoglobin oxygenation. Using the histochemical technique developed by us, we studied the distribution of products of specific reaction for histidine in peripheral blood erythrocytes of pregnant women. The percentage of histidine-positive erythrocytes and their area were evaluated. The relationship between the distribution of the products of the reaction for histidine in peripheral blood erythrocytes of pregnant women and the titer of anti-cytomegalovirus IgG was revealed. The histidine content in peripheral blood erythrocytes of pregnant women with active cytomegalovirus infection was reduced, which impaired heme binding to globin and decreased the formation of oxyhemoglobin.

    Introduction: Pregnant and postpartum women are especially vulnerable to natural disasters. These women suffer from increased risk of physical and mental issues including pregnant related problems. Typhoon Haiyan (Yolanda), which hit the Philippines affected a large number of people and caused devastating damages. During and after the typhoon, pregnant women were forced to live in particularly difficult circumstances. The purpose of this study was to determine concerns and problems regarding public health needs and coping mechanisms among pregnant women during and shortly after the typhoon. Methods: This study employed a cross-sectional design utilizing focus group discussions (FGDs). Participants were 53 women (mean age: 26.6 years old; 42 had children) from four affected communities who were pregnant at the time of the typhoon. FGDs were conducted 4 months after the typhoon, from March 19 to 28, 2014, using semi-structured interviews. Data were analyzed using the qualitative content analysis. Result: Three themes were identified regarding problems and concerns during and after the typhoon: 1) having no ideas what is going to happen during the evacuation, 2) lacking essentials to survive, and 3) being unsure of how to deal with health concerns. Two themes were identified as means of solving issues: 1) finding food for survival and 2) avoiding diseases to save my family. As the pregnant women already had several typhoon experiences without any major problems, they underestimated the catastrophic nature of this typhoon. During the typhoon, the women could not ensure their safety and did not have a strong sense of crisis management. They suffered from hunger, food shortage, and poor sanitation. Moreover, though the women had fear and anxiety regarding their pregnancy, they had no way to resolve these concerns. Pregnant women and their families also suffered from common health problems for which they would usually seek medical services. Under such conditions, the

    Studies in pregnant rabbits were conducted to evaluate if there are any differences in the uptake of thalidomide into the intrauterine compartment and developmental toxicity risk following oral and intravaginal administration. Thalidomide concentrations in maternal plasma, yolk sac cavity (YSC) fluid and embryo following intravaginal administration were 2- to 7-fold lower than their respective levels after oral administration. Ratios of thalidomide concentration in YSC fluid to maternal plasma were similar between these two routes, indicating no difference in uptake into the intrauterine compartment. A rabbit embryo-fetal development study using oral and intravaginal thalidomide administration at 2mg/kg/day (a dose >10,000-fold higher than the expected amount of thalidomide in human semen) did not result in any developmental abnormalities. These data demonstrated no preferential transfer mechanism of thalidomide from vagina to conceptus, and no additional embryo-fetal developmental toxicity risks with thalidomide exposure via the vaginal route.

    Objective To investigate whether elevated IFN-α early in pregnancy is associated with poor pregnancy outcomes and examine its relationship to angiogenic imbalance. Methods Women were enrolled in a case-control longitudinal study of lupus pregnancies. Serum samples obtained monthly through pregnancy were assayed for IFN-α and for antiangiogenic factor, sFlt1, and proangiogenic factor, (PlGF). Each of 28 SLE patients with poor pregnancy outcome was matched to an SLE patient with an uncomplicated pregnancy and to a pregnant healthy control. The effects of IFN-α and/or sFlt1 on-human endothelial cells and endothelial-trophoblast interactions was assessed. Results Compared to SLE patients with uncomplicated pregnancies, patients with preeclampsia had increased IFN-α before clinical symptoms. Non-autoimmune patients destined for preeclampsia did not have increased IFN-α. In SLE patients with low IFN-α, marked angiogenic imbalance (higher sFlt1, lower PlGF and higher sFlt1/PlGF ratios) precedes maternal manifestations of preeclampsia, whereas in SLE with high IFN-α, preeclampsia occurs without evidence of systemic angiogenic imbalance. Treatment of human endothelial cells with sFlt1 induced expression of sFlt1 mRNA, and IFN-α dramatically amplified responses to sFlt1. In a model of spiral artery transformation, only IFN-α and sFlt1 together disrupted the ability of trophoblast cells to remodel endothelial tube structures. Conclusions Our studies identify a new mechanism by which IFN-α induces an antiangiogenic milieu, increases the sensitivity of endothelial cells to sFlt1, and suggest that elevated IFN-α may contribute to pathogenesis of preeclampsia in some SLE pregnancies.

  13. Renal and hormonal effects of water deprivation in late-term pregnant rats.

    PubMed

    Salas, Sofía P; Giacaman, Andrea; Vío, Carlos P

    2004-09-01

    Water-retaining hormones are stimulated during pregnancy allowing normal volume expansion. Because pregnant rats actively retain water, we postulate that water deprivation (WD) would cause a greater reduction in plasma volume in pregnant than in nonpregnant rats. To test this hypothesis, Sprague-Dawley pregnant and nonpregnant rats were water-deprived for 48 hours. At day 19 of pregnancy, or in the corresponding day in nonpregnant rats, they were randomly assigned to either a WD or a control (C) pair-fed group (n=10 to 12 per group). WD significantly reduced body weight, food intake, and creatinine clearance, and increased urinary osmolality in nonpregnant and pregnant rats. WD reduced plasma volume in a similar proportion in nonpregnant and pregnant rats (nonpregnant rats C=13.1+/-0.4, WD=11.0+/-0.2; pregnant rats C=19.4+/-0.7, WD=16.8+/-0.5 mL, P<0.001). Both groups of pregnant rats had a similar reduction in blood pressure. Plasma renin activity (nonpregnant rats C=6.1+/-1.1, WD=20.5+/-2.0; pregnant rats C=49+/-9.7, WD=94+/-12 ng angiotensin I/mL per hour, P<0.001) and plasma aldosterone levels were increased by pregnancy and further increased by WD. WD significantly reduced urinary kallikrein. WD caused a significant reduction in fetal but not placental weights. Present data indicate that 48-hour WD reduced renal kallikrein and further stimulated water-retaining hormones. We speculate that these are compensatory changes contributing to the maintenance of pregnancy in response to WD.

    We have conducted a complex clinical and paraclinical study of 108 women, 78 of which had diabetes and 30 healthy women that made a control group. In 60.3% of the pregnant patients type 1 diabetes was diagnosed, in 11.5%--type 2. Gestational diabetes was found in 28.2% of pregnant women. The vast number of the surveyed pregnant women (52.6%) was diagnosed with moderate and severe (38.5%) degree of the disease. In 12.5% of them the disease was compensated, in 82.1% subcompensated, while in 5.1%--decompensated. In pregnant women with diabetes a high incidence of extragenital diseases was revealed, the most common of which was iron deficiency anemia, which complicated the pregnancy of more than half of the pregnant of the basic group (57.7%), while in the control--in 13.3% of women (p < 0.05). Thyroid diseases in the study group were more than three times more common compared to the control group (47.4% and 13.3%, p < 0.05), while in pregnant women with type 1 diabetes in 55.3% of the patients. Herewith in 29.4% of cases were diagnosed with hypothyroidism, in 52.9--subclinical hypothyroidism, in 25.5% of pregnant women were found autoimmune thyroiditis. These data indicate the need of screening of the pregnant women with diabetes to identify the pathology of the thyroid gland even if the clinical symptom are absent, particularly in the areas of iodine deficiency.

    CDC has developed interim guidelines for health care providers in the United States caring for pregnant women during a Zika virus outbreak. These guidelines include recommendations for pregnant women considering travel to an area with Zika virus transmission and recommendations for screening, testing, and management of pregnant returning travelers. Updates on areas with ongoing Zika virus transmission are available online (http://wwwnc.cdc.gov/travel/notices/). Health care providers should ask all pregnant women about recent travel. Pregnant women with a history of travel to an area with Zika virus transmission and who report two or more symptoms consistent with Zika virus disease (acute onset of fever, maculopapular rash, arthralgia, or conjunctivitis) during or within 2 weeks of travel, or who have ultrasound findings of fetal microcephaly or intracranial calcifications, should be tested for Zika virus infection in consultation with their state or local health department. Testing is not indicated for women without a travel history to an area with Zika virus transmission. In pregnant women with laboratory evidence of Zika virus infection, serial ultrasound examination should be considered to monitor fetal growth and anatomy and referral to a maternal-fetal medicine or infectious disease specialist with expertise in pregnancy management is recommended. There is no specific antiviral treatment for Zika virus; supportive care is recommended.

  20. Views of pregnant women and clinicians regarding discussion of exposure to phthalate plasticizers

    2014-01-01

    Objective This study explores the views of pregnant women and clinicians regarding discussion of exposure to phthalate plasticizers during pregnancy, subsequent to the 2011 Health Canada ban of certain phthalates at a concentration greater than 1000 mg/kg in baby toys. This occurred with no regulation of products to which pregnant women are exposed, such as food packaging and cosmetics. Methods Pregnant women, physicians and midwives were recruited through posters and pamphlets in prenatal clinics in Southwestern Ontario for a semi-structured interview. All interviews were audiotaped, transcribed, and subjected to rigorous qualitative analysis through a grounded theory approach, supported by NVIVO™ software. Themes emerged from line by line, open, and axial coding in an iterative manner. Results Theoretical sufficiency was reached after 23 pregnant women and 11 clinicians had been interviewed. The themes (and subthemes from which they arose) were: Theme I-Information Provision (IA-Sources of Information, IB-Standardization, IC-Constraints, ID-Role of Government); Theme II-Risk (IIA-Significant Risk, IIB-Perceived Relevance, IIC-Reconciliation); and Theme III- Factors Influencing Level of Concern (IIIA-Current Knowledge, IIIB-Demographic Factors). Conclusion To respond to the increasing media and research attention regarding risk of phthalates to women, and pregnant women in particular, national professional organizations should provide patient information. This could include pamphlets on what a pregnant woman should know about phthalates and how they can be avoided, as well as information to clinicians to facilitate this discussion. PMID:24952638
