    The study was conducted to examine effects of a selective copper(I) chelator, neocuproine on the spontaneous or oxytocin-induced contractions in isolated ovariectomized non-pregnant rat, pregnant rat and pregnant human uterus. Uterus activity was evaluated in tissues obtained from bilaterally ovariectomized non-pregnant rats on the 21st day of the operation (n = 24), pregnant rats on the 19-21st day of gestation (n = 24) and women undergoing caesarean section at 38-42 weeks of pregnancy (n = 15). Neocuproine (100 microM) significantly suppressed the amplitude and frequency of the spontaneous contractions in the ovariectomized non-pregnant rat uterus while this agent facilitated the frequency of the spontaneous or oxytocin-induced contractions in the pregnant rat and human uterus without altering the amplitude of these contractions. At high concentration of 200 microM, neocuproine could enhance the amplitude of the contractions in the pregnant uterus. These effects were blocked by a purinergic receptor antagonist, suramin (100 microM) and did not occur following the administration of neocuproine-copper(I) complex or copper(II) chelator cuprizone. alpha, beta-methylene ATP increased the amplitude and frequency of contractions in the pregnant uterus, but not affected the contractions in the ovariectomized non-pregnant rat uterus, and neocuproine potentiated this facilitation effect. However, the suppressive effect of neocuproine on the ovariectomized non-pregnant rat uterus increased in the presence of alpha,beta-methylene ATP. Beta-adrenoceptor blocker, propranolol or nitric oxide synthase inhibitor, L-nitroarginine did not affect the responses to neocuproine. These findings suggest that neocuproine can affect the uterus contractile activity by modulation purinergic excitatory responses and that copper(I)-sensitive mechanisms may play a role in this effect.

    Data are limited on hereditary angioedema (HAE) in pregnant women and the safety and efficacy of therapies for treatment and prevention of HAE attacks during pregnancy. Prospective studies are unlikely given the rarity of HAE and ethical considerations regarding enrollment of pregnant female subjects in clinical trials. A retrospective analysis of clinical trial and compassionate-use data was conducted to identify subjects who received nanofiltered C1 esterase inhibitor (C1 INH-nf; human) during pregnancy. This study evaluates the efficacy and safety of human C1 INH-nf for treatment and prevention of HAE attacks in pregnant women. Data from pregnant subjects enrolled in either open-label extensions of two randomized, double-blind, placebo-controlled trials of C1 INH-nf or in a compassionate-use program were retrospectively analyzed for efficacy (e.g., total attacks, attack frequency during prophylaxis, and monthly attack rates) and safety (e.g., pregnancy outcomes and adverse events). C1 INH-nf was administered as acute treatment, preprocedural prophylaxis, or routine prophylaxis. C1 INH-nf prophylaxis substantially reduced monthly attack rates. Of 16 subjects, 13 delivered 14 healthy neonates (1 set of twins). Two adverse fetal outcomes were reported; neither was considered by the principal investigator to be related to C1 INH-nf. One subject's pregnancy outcome was unknown. This analysis shows a favorable risk-benefit profile for C1 INH-nf for managing HAE during pregnancy. NCT Identifier: NCT00438815; NCT00462709.

    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.

  20. Changes in adrenergic receptors in the pregnant human uterine cervix following mifepristone or placebo treatment in the first trimester.

    PubMed

    Kovács, L; Falkay, G

    1993-01-01

    There is increasing evidence that the antiprogesterone mifepristone (RU-486) can dilate the cervix of pregnant women. The uterine and cervical smooth muscle contractile response to adrenergic agonists is regulated by the steroidal environment. This study was undertaken to assess the effects of treatment with RU-486 on the concentrations of alpha- and beta-adrenoceptors in cervical crude membranes from pregnant women using a radioligand binding assay. A special needle biopsy technique was used for human cervical specimens. The probable relative oestrogen dominance due to the antiprogesterone treatment selectively decreased the alpha-2 adrenoceptor in human cervix at an early stage of gestation. This finding was similar to that reported earlier in pregnant rabbits. The existence of a functionally distinct alpha-2 adrenergic receptor subtype will have important implications for our understanding of the contractile activity of the cervix.

  1. Regulation of matrix metalloproteinase-9 transcription in squamous cell carcinoma of uterine cervix: the role of human papillomavirus gene E2 expression and activation of transcription factor NF-kappaB.

    Matrix metalloproteinase-9 (MMP-9) plays an important role in initiation and progression of squamous cell carcinoma (SCC) of human uterine cervix. Regulation of MMP-9 expression in such tumors is insufficiently studied. Involvement of the human papillomavirus (HPV) gene E2 and transcription factor NF-kappaB in the regulation of MMP-9 transcription has been shown in some model systems and types of malignant tumors. The present work was mainly designed to reveal a possible role of the HPV gene E2 and transcription factor NF-kappaB in the induction of MMP-9 expression in SCC. Specimens of tumor and corresponding adjacent normal tissue from 26 patients with SCC of the uterine cervix were studied. The intact E2 frame was observed in 19 of 26 (73.1%), the E2 gene mRNA was expressed in 10 of 15 (66.7%), NF-kappaB was activated in 17 of 23 (73.9%), and the expression of MMP-9 mRNA was recorded in 10 of 20 (50%) of the informative cases. The MMP-9 transcription did not correlate with gene E2 status, but in all cases correlated with the activation of NF-kappaB transcription factor (10 of 10 vs. 5 of 10 MMP-9-negative cases, p = 0.016). Thus, the NF-kappaB role has been proved in the regulation of MMP-9 transcription in SCC. There was no correlation of the E2 status and MMP-9 expression with clinical/morphological characteristics of the tumors: size, local invasiveness, metastasizing into regional lymph nodes, and level of differentiation. The high intensity of NF-kappaB activation correlated with low degree of differentiation of the tumors studied (p = 0.044). These findings suggested that NF-kappaB should be a molecular factor of the poor prognosis of human SCC.

    Smooth muscle cells isolated from the myometrium of a pregnant woman at term were infected with a replication-defective adenovirus vector expressing the E6/E7 proteins of human papilloma virus 16. A clonal line, PHM1-41, was selected by resistance to Geneticin and examined for maintenance of smooth muscle phenotype and response to oxytocin. The immortalized cell line retained morphological characteristics of proliferating smooth muscle cells in culture for up to 22 passages and has been used for over 2 years. The cells expressed smooth muscle-specific alpha-actin and retained estrogen receptors. Oxytocin receptors were present, as measured by whole cell binding assay using the oxytocin antagonist 125I-d(CH2)5[Tyr-(Me)2,Thr4,-Orn8,Tyr9-NH2] as ligand and oxytocin as competitor. The data were best described by a one-site binding model, with a Kd of 0.36 nM and a binding site concentration of 37 fmol/microgram DNA. PHM1-41 cells responded to oxytocin with an increase in intracellular free calcium (EC50 15 nM) and an increase in phosphatidylinositol turnover. Oxytocin-stimulated phosphatidylinositol turnover was inhibited by preincubation with the cAMP analog CPT-cAMP. This immortalized myometrial cell line should prove useful for studies relating to human myometrial function. PMID:8828850

    The serological testing algorithm for recent human immunodeficiency virus (HIV) seroconversion (STARHS) was employed to estimate HIV incidence among pregnant women from São Paulo, Brazil. A cross-sectional study (1999 to 2002) showed an incidence of infection of 0.2 per 100 pregnant women per year (95% confidence interval, 0.041 to 0.608). Western blot profiles suggested an association between results of the STARHS analysis and gp41/gp31 bands. PMID:15750127

    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.

  5. Effect of isoproterenol on uptake of calcium-45 by pregnant human and rat myometrium.

    1976-05-01

    Rat and human myometria contract is response to substitution of external Na+ with Li+. This contraction was accompanied by elevation of 45Ca uptake in rat but not human uterus. The lanthanum technique failed to demonstrate elevation of cellular 45Ca in human myometrium by Li+ substitution. It also failed to demonstrate reduction of Li-elevated 45Ca uptake by isoproterenol or drugs considered to inhibit calcium influx, in rat myometrium although these drugs prevented Li-induced contraction. In human myometrium, isoproterenol increased 45Ca uptake. This probably represents increased extracellular calcium binding. Isoproterenol relaxed depolarized human myometrium provided that the external calcium had been removed for 15 minutes.

    Background: Research says that diabetes may develop in over 10% of non-diabetic pregnant women. Diabetes which generally occurs late in second trimester and third trimester of pregnancy, it is called gestational diabetes. Overweight or suffering from obesity before pregnancy is type 2 diabetes risk factor. In most cases, diabetic symptoms disappear after delivery. HLA-G has an important role both in mother and fetus tolerance during pregnancy, it may also be effective in the protection of pancreatic islet cells. In this study, concentration of these molecules in pregnant women with gestational diabetes in comparison with normal pregnant women was investigated. Methods: In this case-control study, we measured serum HLA-G levels in 24 pregnant women with gestational diabetes compared with 30 normal pregnant women using sandwich ELISA. Results: HLA-G levels were significantly low in pregnant women with gestational diabetes in contrast to normal pregnant women (P=0.001). Conclusion: In this study, we found that HLA-G levels were reduced in women with gestational diabetes compared with control group. Therefore, it is suggested that measurement of HLA-G in pregnant women can be considered as an indicator in prognosis of gestational diabetes. PMID:27757202

    Problem CD11cHI human decidual macrophages express several isoforms of CD1 molecules. Their expression pattern and function required investigation. Method of Study CD11cHI macrophages were isolated from decidua. Expression of CD1 isoforms and their ability to present lipid antigens to T cells was studied. Results CD1a, CD1c, and CD1d were all expressed on CD11cHI dMϕ, a pattern differing from those previously observed. Exposure of peripheral monocytes and dendritic cells to lipid isolates from decidua led to increased surface CD1a levels only. The CD1a and CD1c on dMϕ were able to present the appropriate lipid antigens to lipid antigen-specific T cells. Finally, autoreactivity of decidual T cells to CD1a was observed. Conclusion The unique pattern of expression of CD1 isoforms on CD11cHI dMϕ is consistent with organ-specific roles of CD1 in human T cell responses. dMϕ are able to present lipid antigens to both peripheral and decidual T cells and are major antigen presenting cells in human de-cidua.

    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.

    Summary Human T-cell lymphotropic virus type 1(HTLV-1) is associated with adult T-cell leukemia, tropical spastic paraparesis, and other immune-mediated diseases. There are reports of groups with high prevalences of HTLV-1 infection in Peru, but there is limited knowledge of the epidemiology of infection or which routes of infection are most important. We studied 2492 women presenting to a large maternity hospital in Lima for prenatal, delivery, or abortion services. HTLV-1 seropositivity was confirmed in 42 women (1.7%; 95% confidence interval, 1.2–2.2). Seroprevalence increased with age but did not vary by region of birth or recency of migration to Lima. Age greater than 30 years and sexual intercourse before 20 years of age were strongly and independently associated with infection. History of abortion and history of transfusion were of borderline significance. Women whose male partner had a characteristic that might be a marker for risk of sexually transmitted infections were also more likely to be infected. HTLV-1 is common among Peruvians throughout the country and is maintained by a low level of neonatally acquired infection that is amplified by sexual transmission. In addition to screening of the blood supply, instituted in 1997, programs designed to reduce neonatal and sexual transmission should be effective. PMID:16773029

    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 T-cell lymphotropic virus type 1(HTLV-1) is associated with adult T-cell leukemia, tropical spastic paraparesis, and other immune-mediated diseases. There are reports of groups with high prevalences of HTLV-1 infection in Peru, but there is limited knowledge of the epidemiology of infection or which routes of infection are most important. We studied 2,492 women presenting to a large maternity hospital in Lima for prenatal, delivery, or abortion services. HTLV-1 seropositivity was confirmed in 42 women (1.7%; 95% confidence interval, 1.2-2.2). Seroprevalence increased with age but did not vary by region of birth or recency of migration to Lima. Age greater than 30 years and sexual intercourse before 20 years of age were strongly and independently associated with infection. History of abortion and history of transfusion were of borderline significance. Women whose male partner had a characteristic that might be a marker for risk of sexually transmitted infections were also more likely to be infected. HTLV-1 is common among Peruvians throughout the country and is maintained by a low level of neonatally acquired infection that is amplified by sexual transmission. In addition to screening of the blood supply, instituted in 1997, programs designed to reduce neonatal and sexual transmission should be effective.

  15. Optimisation of an oviposition protocol employing human chorionic and pregnant mare serum gonadotropins in the Barred Frog Mixophyes fasciolatus (Myobatrachidae)

    Background Protocols for the hormonal induction of ovulation and oviposition are essential tools for managing threatened amphibians with assisted reproduction, but responses vary greatly between species and even broad taxon groups. Consequently, it is necessary to assess effectiveness of such protocols in representative species when new taxa become targets for induction. The threatened genus Mixophyes (family Myobatrachidae) has amongst the highest proportion of endangered species of all the Australian amphibians. This study developed and optimised the induction of oviposition in a non-threatened member of this taxon, the great barred frog (Mixophyes fasciolatus). Methods Gravid female M. fasciolatus were induced to oviposit on one or more occasions by administration of human chorionic gonadotropin (hCG) with or without priming with pregnant mare serum gonadotropin (PMSG). Treatments involved variations in hormone doses and combinations (administered via injection into the dorsal lymph sacs), and timing of administration. Pituitary homogenates from an unrelated bufonid species (Rhinella marina) were also examined with hCG. Results When injected alone, hCG (900 to 1400 IU) induced oviposition. However, priming with two time dependent doses of PMSG (50 IU, 25 IU) increased responses, with lower doses of hCG (200 IU). Priming increased response rates in females from around 30% (hCG alone) to more than 50% (p = 0.035), and up to 67%. Increasing the interval between the first PMSG dose and first hCG dose from 3 to 6 days also produced significant improvement (p<0.001). Heterologous pituitary extracts administered with hCG were no more effective than hCG alone (p = 0.628). Conclusions This study found that M. fasciolatus is amongst the few amphibian species (including Xenopus (Silurana) and some bufonids) that respond well to the induction of ovulation utilising mammalian gonadotropins (hCG). The optimal protocol for M. fasciolatus involved two priming doses of

    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

  18. 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.

    To establish current seroprevalence of human T cell leukaemia/lymphoma virus type I (HTLV-I) infection in some low- and high-risk populations from Slovenia, 10,369 and 869 serum samples collected during Slovenian 1994 unlinked surveys of human immunodeficiency viruses seroprevalence in pregnant women and patients attending venereological outpatient services, respectively, and 219 serum samples collected from Slovenian intravenous drug abusers during 1995 and 1996, were screened for the presence of anti-HTLV-I antibodies using commercial particle agglutination test Serodia HTLV-I (Fujirebio, Tokyo, Japan). Only one sample obtained from a pregnant woman was found repeatedly positive in the screening test. Presence of anti-HTLV-I antibodies in the reactive sample was undoubtedly confirmed with supplemental Western blot test. The prevalence of antibodies to HTLV-I in the Slovenian population might be somewhere between one in 10,000 (0.01%) and one in 15,000 (0.0066%), which is similar or even higher to prevalence rates in other European countries.

    Inflammatory mediators, including prostaglandins, cytokines, and chemokines, are strongly implicated in the mechanism of human labor, though their precise roles remain unknown. Here we demonstrate that interleukin 1 beta (IL-1beta) significantly increased the expression and release of interleukin-8 (CXCL8), monocyte chemotactic protein-1 (CCL2), and granulocyte macrophage colony-stimulating factor (CSF2) by primary human myometrial cells. However, this effect was repressed by prostaglandin E(2) (PGE(2)). As PGE(2) can activate four distinct PGE(2) receptors (EP(1), EP(2), EP(3), and EP(4)) to elicit various responses, we sought to define the EP receptor(s) responsible for this repression. Using selective EP receptor agonists and a selective EP(4) antagonist, we show that PGE(2) mediates the repression of IL-1beta-induced release of CXCL8, CCL2, and CSF2 via activation of the EP(2) and EP(4) receptors. The use of siRNA gene-specific knockdown further confirmed a role for both receptors. Real-time RT-PCR demonstrated that EP(2) was the most highly expressed of all four EP receptors at the mRNA level in human myometrial cells, and immunocytochemistry showed that EP(2) protein is abundantly present throughout the cells. Interestingly, PGE(2) does not appear to reduce mRNA expression of CXCL8, CCL2, and CSF2. Our results demonstrate that PGE(2) can elicit anti-inflammatory responses via activation of the EP(2) and EP(4) receptors in lower segment term pregnant human myometrial cells. Further elucidation of the EP receptor-mediated signaling pathways in the pregnant human uterus may be beneficial for optimizing the maintenance of pregnancy, induction of labor or indeed treatment of preterm labor.

    Background In Sub-Saharan Africa, prevalence estimates of hepatitis C virus (HCV) vary widely. Objectives To assess the prevalence of HCV infection among HIV-infected, pregnant women screened for a large clinical trial in Lilongwe, Malawi. Study design Plasma from 2041 HIV-infected, pregnant women was screened for anti-HCV IgG using a chemiluminiscent immunometric assay (CIA). Specimens with a signal-cut-off ratio ≥ 1.00 were considered reactive and those with S/Co ratio < 1.00 non-reactive. All CIA-reactive specimens were tested by a recombinant immunoblot assay (RIBA) for anti-HCV and by PCR for HCV RNA. Results Of 2041 specimens, 110 (5.3%, 95% CI: 4.5–6.5%) were CIA reactive. Of the 109 CIA reactive specimens available for RIBA testing, 2 (1.8%) were positive, 28 (25.7%) were indeterminate, and 79 (72.5%) were negative. All CIA-reactive specimens were HCV RNA negative (n = 110). The estimated HCV prevalence based on the screening assay alone was 5.3%; based on supplemental RIBA testing, the status of HCV infection remained indeterminate in 1.4% (28/2040, 95% CI: 0.1–2.0) and the prevalence of confirmed HCV infections was 0.1% (2/2040, 95% CI: 0–0.4%). Conclusions HCV seroprevalence among HIV-infected, pregnant women in Malawi confirmed by supplemental RIBA HCV 3.0 is low (0.1%); CIA showed a high false-reactivity rate in this population.

    In 3 adult female cheetahs, induced-superovulation treatment was conducted, by means of 200 IU of pregnant mare serum gonadotropin (PMSG) and 100 IU of human chorionic gonadotropin (hCG) 80 hr after PMSG. The administration of PMSG created a sharp increase in the estradiol-17beta concentration, resulting in 232 pg/ml 8 hr later in one specimen out of three. The hCG administration showed an increase in the progesterone concentration of 2.29 ng/ml 46 hr later. In addition, after direct observation of the ovary surface by laparoscopy, 5 follicles in the right ovary over 2 mm in diameter, and 7 corpora lutea (5 in the right ovary and 2 in the left) were found. It is assumed that ovulation can be induced with hCG after 80 hr on PMSG during a cheetah's diestrus or proestrus.

    Human T-cell leukemia virus type 1 (HTLV-1) is the causative agent of adult T-cell leukemia-lymphoma (ATL), which is difficult to cure. In Japan, a nationwide HTLV-1 screening test in pregnant women has been recommended since 2011. A 30-year-old woman was diagnosed as being an HTLV-1 carrier in her previous pregnancy. During the current pregnancy, she had persistent fever and cough. Although she had treatment with antibiotics, peripheral white blood cell count remained high, with an abnormal lymphocyte count. Given that she was an HTLV-1 carrier, she was diagnosed with unfavorable chronic ATL (aggressive ATL) at 12 weeks gestation. After pregnancy termination, her ATL status became favorable chronic ATL (indolent ATL). Therefore, watchful waiting was performed until disease progression. This is the first case report of chronic ATL in early pregnancy, in a woman already diagnosed as an HTLV-1 carrier on screening test. PMID:26663442

    Nifedipine is a dihydropyridine calcium channel blocker used for the treatment of hypertension in pregnant women. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for analysis of nifedipine in human plasma and amniotic fluid. Separation of nifedipine and nitrendipine (IS) was performed using a LiChroCART(®) RP-Select B column and a mixture of water:acetonitrile:glacial acetic acid (30:70:0.5 v/v) as the mobile phase. Aliquots of 500μL of biological samples were extracted at pH 13 using dichloromethane:n-pentane (3:7 v/v). The validated method was applied to a study of the pharmacokinetics of nifedipine in human plasma and amniotic fluid samples collected up to 12h after administration of the last slow-release nifedipine (20mg/12h) dose to 12 hypertensive pregnant women. The estimated pharmacokinetic parameters of nifedipine showed a mean AUC(0-12) of 250.2ngh/mL, ClT/F of 89.2L/h, Vd/F of 600.0L and t1/2 5.1h. The mean amniotic fluid/plasma concentration ratio was 0.05. The methods proved to be highly sensitive by showing a lower quantification limit of 0.1ng/mL for both matrices. And this study reports for the first time the complete development and validation of the method to quantify nifedipine in amniotic fluid using LC-MS-MS.

    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.

    Objective To determine the stiffness of the pregnant uterine cervix in vivo. Method Five women in early pregnancy and six women in late pregnancy were included. The EndoFlip is a 1-m-long probe with a 12-cm-long bag mounted on the tip. The tip of the probe was inserted into the cervical canal. Sensors spaced at 0.5-cm intervals along the probe were used to determine 16 serial cross-sectional areas of the bag. The diameter of the cervical canal could thereby be determined during inflation with up to 50 ml saline solution. Tissue stiffness was calculated from the geometric profiles and the pressure-strain elastic modulus (EP) at each sensor site. Three parts of the cervix were defined: the uterus-near part, the middle and the vaginal part. The EPmax was defined as the highest EP detected along the cervical canal. Results The EPmax was always found in the middle part of the cervix. The median EPmax was 243 kPa (IQR, 67–422 kPa) for the early pregnant women and 5 kPa (IQR, 4–15 kPa) for those at term. In the early pregnant women the stiffness differed along the cervical length (p<0.05) whereas difference along the cervix was not found for late pregnant women. A positive correlation coefficient (Spearman’s rho) was established between the EPs of the uterus-near and the middle part (0.84), between the vaginal and the middle part (0.81), and between the uterus-near and the vaginal part (0.85). Conclusion This new method can estimate the stiffness along the cervical canal in vivo. This method may be useful in the clinical examination of the biomechanical properties of the uterine cervix.

    Uterine contractions are tightly regulated by the electrical activity of myometrial smooth muscle cells (MSMCs). These cells require a depolarizing current to initiate Ca(2+) 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 Gd(3+)-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 Ca(2+) 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 Gd(3+) 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 Gd(3+)-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.

    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.

  15. Correlation between selective inhibition of the cyclic nucleotide phosphodiesterases and the contractile activity in human pregnant myometrium near term.

    The present study was carried out to determine the ability of various pharmacological agents to selectively inhibit each cytosolic form of phosphodiesterase isolated from the longitudinal layer of human myometria near term. Among the drugs tested, zaprinast specifically inhibits the first form of PDE which hydrolyses both substrates (cAMP and cGMP) and is stimulated by the Ca2+-calmodulin complex. A second form of PDE specific for cAMP hydrolysis and Ca2+-calmodulin insensitive is only present during pregnancy. Rolipram is the most potent and selective inhibitor of this second form. It is also the most efficient compound to inhibit in vitro the spontaneous contractions of near term myometria. The double effect of rolipram suggests an important role of the second form of PDE in the mechanisms of contractility during the pregnancy. In addition rolipram or other derivatives might be of a therapeutic interest in the prevention of prematurity in so far as they are devoid of undesirable maternal and fetal side effects.

    Neonatal alloimmune thrombocytopenia (NAIT) is a clinical syndrome that resembles hemolytic disease of the newborn, affecting the platelets only. The thrombocytopenia results from the maternal alloantibodies reacting with specific human platelet antigens (HPAs) on the fetal platelets. Forty-four maternal plasma samples were screened for platelet alloantibodies using qualitative solid phase enzyme-linked immunosorbent assay (ELISA) commercial kit (LIFECODES Pakplus, Hologic Gen-Probe GTI Diagnostics, Waukesha, WI, USA), and both the maternal and the corresponding cord blood samples were genotyped (LIFECODES ThromboType, Hologic Gen-Probe GTI Diagnostics, Waukesha, WI, USA). HPA genotyping results correlated with the genetic frequencies in the Taiwan population. A total of 34 newborns (77.3%) had partial HPA genotyping mismatches with the corresponding mothers. The most common partial mismatches between mothers and neonates in HPA genotypes were 13 (29.5%) in both HPA-3b and HPA-15a, followed by 12 (27.3%) in HPA-15b, and 8 (18.2%) in HPA-3a. The frequencies of homozygotic mother with heterozygotic neonate were 15.9% in both HPA-3a and HPA-15b, 9.1% in HPA-15a, 6.8% in HPA-3b, and 2.3% in both HPA-2a and HPA-6a. In this study, maternal HPA antibodies were found in five samples, whereas HLA class I antibodies were found in seven maternal plasma samples from the antibody screen. The results from this study have demonstrated that HPA mismatch is not the main cause for the production of HPA alloantibodies.

    The Pregnant Guppy is a modified Boeing B-377 Stratocruiser used to transport the S-IV (second) stage for the Saturn I launch vehicle between manufacturing facilities on the West coast, and testing and launch facilities in the Southeast. The fuselage of the B-377 was lengthened to accommodate the S-IV stage and the plane's cabin section was enlarged to approximately double its normal volume. The idea was originated by John M. Conroy of Aero Spaceliners, Incorporated, in Van Nuys, California. The former Stratocruiser became a B-377 PG: the Pregnant Guppy. This photograph depicts the Pregnant Guppy in flight.

  18. Effects of ethanol on superovulation in the immature rat following pregnant mare's serum gonadotropin (PMSG) or PMSG and human chorionic gonadotropin treatment.

    We sought to determine whether superovulation could occur in immature rats on a 5% ethanol diet and treated with pregnant mare's serum gonadotropin (PMSG) alone or with human chorionic gonadotropin (hCG). Holtzman female rats were divided into five groups at 20 days of age. Six rats (Group I) were killed at that age. Ten rats (Group II) were placed on an ad libitum laboratory chow diet and killed on Day 33. Twenty-four rats (Group III) were placed on an ad libitum laboratory chow diet. Twenty-four rats (Group IV) were placed on 5% ethanol liquid diet, while 24 rats in Group V were pair-fed with the animals in Group IV. At 30 days of age, 12 rats from each Group, III, IV, and V, received 25 IU of PMSG s.c. and were killed 74-76 h later. The remaining 12 rats from each Group, III, IV and V, received 25 IU of PMSG and 54-56 h later received 10 IU of hCG and were killed 20 h later. Ovulation occurred in all the rats of Groups III and V that received PMSG alone or with hCG. In the ethanol-treated rats that received PMSG alone, 75% ovulated, while 92% ovulated that received PMSG and hCG. The number of ova shed in the ethanol-PMSG-treated rats was significantly less than in the ethanol-PMSG-hCG-treated animals and in the controls. The uterine weights and morphology of the animals in Group IV were similar to those in Groups III and V. The study indicates that ethanol does not have a direct gonadotoxic effect on the ovary but indicates that ethanol has an effect on the hypothalamus and/or the pituitary, thereby disrupting the synthesis and/or release of luteinizing hormone releasing hormone (LHRH) or luteinizing hormone (LH).

    To assess the prevalence and incidence of human T-cell lymphotropic virus type I (HTLV-I), 4,234 pregnant women of different ethnic origins were tested before each delivery between 1991 and 1997 in a high HTLV-I endemic area of French Guiana. HTLV-I was significantly more prevalent among ethnic groups of African descent as the Noir-Marrons (4.8%, 95% confidence interval [CI]: 4.0-5.6) and Haitians (5%, 95% CI 1.6-8.4). An age dependence of HTLV-I seroprevalence was observed. The mean age of Noir-Marron HTLV-I seronegative women was lower than for HTLV-I seropositive women (24. 7 vs. 28.6, p < 0.001). A decline in HTLV-I seroprevalence was observed, particularly in the Noir-Marron younger than 21 years old (p = 0.04). For five HTLV-I seroconversions observed, the incidence per 100 women-years in the Noir-Marron group was 0.19 (95% CI 0.02-0. 35) for all women, 0.32 in those 25 years old or younger (95% CI 0-0. 64), and 0.07 in those older than 25 years (95% CI 0-0.2). This observation was inconsistent with HTLV-I seroprevalence observed for those 25 years old or younger (2.8%) and those older than 25 (8.3%). These data demonstrate, for the first time outside Japan, a birth cohort effect for HTLV-I in a highly endemic ethnic group.

    This study investigates dietary behaviour and the perceived role of food for health of pregnant versus non-pregnant women. Data were collected between 15 January 2003 and 15 March 2003 in Belgium. One hundred and forty-eight pregnant and 130 non-pregnant women aged between 20 and 40 years completed a self-administered questionnaire about their dietary behaviour and nutritional attitudes. Both sub-samples match with respect to individual factors such as relevant socio-demographics and general food perceptions. Pregnant women report higher consumption of fruits, which results in a better score for fibre intake. They also report higher consumption of beef and dairy products, as well as a higher fat intake. No difference in fish consumption between pregnant and non-pregnant women is observed. In line with recommendations, pregnant women report reduced consumption of food products with heightened safety-related risks, lower use of alcohol and tobacco, and safer food handling practices. Reduced intake of raw vegetables for food safety reasons is not compensated by higher intake of cooked vegetables. Pregnant women also report a lower frequency of moderate physical activity. Most differences in food choice by pregnant versus non-pregnant women pertain to the avoidance of specific, potentially harmful food groups. A substantial share of pregnant women does not follow upon recommendations with respect to alcohol use and exposure to tobacco. Personal medical sources for pregnant women and personal social sources for non-pregnant women are reported as the most attended sources of diet-related information. The perceived role of food for health is not different between pregnant and non-pregnant women, and there were no significant interaction effects between pregnancy and presence of children, which indicates that the observed differences in dietary behaviour can be attributed to the state of being pregnant.

    Smoking remains a major public health concern during pregnancy and is associated with numerous adverse effects. Recently the clearance of nicotine (NIC) and cotinine (COT) was shown to be substantially increased in pregnant women compared to non-pregnant controls. The present study investigated the usefulness of the rabbit for studying the molecular basis for the observed changes in NIC and COT disposition during pregnancy. NIC was largely metabolized to COT in rabbit liver microsomes (approximately 50% of total metabolism) with significant amounts of nicotine-N’-oxide and nornicotine also being detected. The conversion of NIC to COT was also detected in rabbit placental and fetal liver microsomes albeit at only a fraction of the rate in adult rabbit liver microsomes. The major products of COT metabolism in rabbit liver microsomes were 5’-hydroxycotinine, cotinine-N’-oxide and norcotinine. Differences between human and rabbit liver were most apparent for COT, with the major human metabolite 3’-hydroxycotinine, being formed at only low levels in rabbit liver microsomes. Pregnancy had no effect on the metabolism of NIC or on the expression of CYP2A6 immunoreactive proteins in rabbit liver microsomes. These studies provide a complete quantitative assessment of NIC metabolism in rabbit liver microsomes and suggest that the rabbit may not be an appropriate animal model to study the effects of pregnancy on NIC and COT metabolism. However, a molecular understanding of these effects is essential for prediction of the pharmacological and toxicological consequences of smoking during pregnancy. PMID:18686186

    Approaches employed in counseling pregnant adolescents at the Crittenton Clinic in Boston are described. Concentrating on concrete issues of management of the pregnancy -- supplying information and exploring the pros and cons of various alternatives are advocated; probing into the psychological and emotional background of the pregnant adolescent is discouraged. Counseling about contraceptives and taking into account each individual situation are considered essential. Case studies are reviewed and figures representing the attitudes and contraceptive use of patients 1 year after abortion are presented. It is considered important to establish a trusting relationship with the adolescent, which will increase the likelihood that she will return for follow-up and additional help if she needs it.

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).

    2014-09-01

    Through their ability to reveal and record abnormal chromosomes, whether inherited or accidentally altered, chromosomal studies, known as karyotyping, became the basis upon which medical genetics was constructed. The techniques involved became the visual evidence that confirmed a medical examination and were configured as a material culture for redefining health and disease, or the normal and the abnormal, in cytological terms. I will show that the study of foetal cells obtained by amniocentesis led to the stabilisation of karyotyping in its own right, while also keeping pregnant women under the vigilant medical eye. In the absence of any other examination, prenatal diagnosis by foetal karyotyping became autonomous from the foetal body. Although medical cytogenetics was practiced on an individual basis, data collected about patients over time contributed to the construction of population figures regarding birth defects. I study this complex trajectory by focussing on a Unit for Cytogenetics created in 1962 at the Clínica de la Concepción in Madrid. I incorporate the work and training of the clinicians who created the unit, and worked there as well as at other units in the large new hospitals of the national health care system built in Madrid during the mid-1960s and early 1970s.

    According to the Canadian Association of Family Planning 85% of adolescents are unprotected at their 1st intercourse, and 16% become pregnant; only 20% of those having a regular sex life use contraception. Women below 20 contributed to 17% of births in 1976 in Canada; in the same year 41.5% of all new mothers were unmarried, and only 27.5% of new fathers accepted responsibility for their paternity. These figures give an idea of the extent of the problem of unwanted pregnancy among adolescents, a problem shared by all Western countries. The adolescent mother is too young to know what she wants, not to mention to accept responsibility for the caring of an infant. Risk of maternal mortality is twice as great among teenage mothers, and so is risk of infant death, mostly due to prematurity. Nurses can play a very important role in helping adolescent mothers, and they must never project their moral values on their young patients.

    2000-12-01

    This article is excerpted from a report by Amnesty International, entitled "Not Part of My Sentence": Violations of the Human Rights of Women in Custody, March 1999. The article describes violations of the human rights of pregnant women and mothers who are incarcerated in prisons and jails in the United States. Many of the practices employed are not in compliance with international standards and are also prohibited by federal and state laws in the United States. In 1997-1998, more than 2200 pregnant women were imprisoned and more than 1300 babies were born in prisons. In at least 40 states, babies are taken from their imprisoned mothers almost immediately after birth or at discharge from the hospital. International standards restrict the use of restraints to limited situations. Restraints are used as a matter of course in the United States, including on women in labor or immediately after birth, who may be taken to a hospital in handcuffs and chained by a leg to the bed. Amnesty International calls for governments and authorities to take urgent action that will ensure that the laws, regulations, policies, and practices for which they are responsible rigorously conform to international standards and respect the human rights of women deprived of their liberty.

    1985-12-15

    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.

  20. Comparison of a Baculovirus-Based VP2 Enzyme Immunoassay (EIA) to an Escherichia coli-Based VP1 EIA for Detection of Human Parvovirus B19 Immunoglobulin M and Immunoglobulin G in Sera of Pregnant Women

    A split-sample study was conducted to evaluate the clinical performance of an enzyme immunoassay that detects the human parvovirus B19 virus (B19V) immunoglobulin M (IgM) or IgG in the sera of pregnant women. The initial study compared a baculovirus-expressed VP2 enzyme immunoassay (BVP2 EIA) (Biotrin International Inc., Dublin, Ireland) with the currently available and commonly used Escherichia coli-expressed VP1 enzyme immunoassay (EVP1 EIA) (MRL Diagnostics, Cypress, Calif.). There was a high degree of agreement between the two assays in the detection of IgM antibodies (283 of 307 [92.2%]) or IgG antibodies (279 of 311 [89.7%]), with the majority of discrepancies (IgM, 17 of 24 [71%]; IgG, 16 of 31 [50%]) being due to equivocal data obtained with the EVP1 EIA. Specimens with discordant BVP2 EIA and EVP1 EIA results (23 of 24 IgM and 32 of 32 IgG results) were analyzed further by baculovirus-based VP1 immunofluorescence assays (BVP1 IFAs) (Biotrin International). The BVP2 EIA and BVP1 IFA results for 20 of 23 and 28 of 32 specimens for IgM and IgG, respectively, were concordant. In contrast, the EVP1 EIA and BVP1 IFA data for only 3 of 23 and 4 of 32 specimens for IgM and IgG, respectively, were in agreement, despite the fact that the same capsid antigen was used. Both the BVP2 EIAs and BVP1 IFAs utilize a conformational viral capsid antigen, while the EVP1 EIA uses a denatured viral capsid antigen. In conclusion, the BVP2 EIAs produced far fewer equivocal results for IgM and IgG, correlating more closely to the confirmatory BVP IFAs, than did the EVP1 EIAs and proved to be more accurate for detecting B19V antibodies in the sera of pregnant women.

    A Prospective pharmacovigilance survey of adverse drug reactions (ADRs) in pregnant women was performed in collaboration with gynaecologists and obstetricians of Midi-Pyrenees area (south west of france). The aim of the study was to evaluate the incidence of adverse drug reactions in pregnant women. The incidence of ADRs in pregnant women was low: 0.3%. Moreover, a retrospective pharmacoepidemiological study was conducted to characterize ADRs in pregnant women. Reports of ADRs collected in the Midi-Pyrenees pharmacovigilance centre from 1982 to 2002 were used: type of ADRs, drugs involved and potential risk factors were compared for pregnant women and for age-matched non pregnant women. Forty seven and 94 reports of ADRs were collected in pregnant and non-pregnant women respectively. Anaphylactic reactions were only observed in pregnant women (3 cases, p = 0.04). We observed 1 ADR related stillbirth (due to anaphylactic reaction) in pregnant women. Drugs for gynaecological and cardiovascular systems were more frequently involved in ADRs in pregnant women than in controls. ADRs mainly occurred during the third trimester of pregnancy. The incidence of ADRs is very low in pregnant women. However, one must pay attention on the risk of anaphylactic reactions in pregnant women. PMID:18206108

    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.

    To describe characteristics, referrals, service utilization, and self-reported quit rates among pregnant and non-pregnant women enrolled in a smoking cessation quitline. This information can be used to improve strategies to increase pregnant and non-pregnant smokers' use of quitlines. We examined tobacco use characteristics, referral sources, and use of services among 1,718 pregnant and 24,321 non-pregnant women aged 18-44 years enrolled in quitline services in 10 states during 2006-2008. We examined self-reported 30-day quit rates 7 months after enrollment among 246 pregnant and 4,123 non-pregnant women and, within groups, used Chi-square tests to compare quit rates by type of service received. The majority of pregnant and non-pregnant callers, respectively, smoked ≥10 cigarettes per day (62 %; 83 %), had recently attempted to quit (55 %; 58 %), smoked 5 or minutes after waking (59 %; 55 %), and lived with a smoker (63 %; 48 %). Of callers, 24.3 % of pregnant and 36.4 % of non-pregnant women were uninsured. Pregnant callers heard about the quitline most often from a health care provider (50 %) and non-pregnant callers most often through mass media (59 %). Over half of pregnant (52 %) and non-pregnant (57 %) women received self-help materials only, the remainder received counseling. Self-reported quit rates at 7 months after enrollment in the subsample were 26.4 % for pregnant women and 22.6 % for non-pregnant women. Quitlines provide needed services for pregnant and non-pregnant smokers, many of whom are uninsured. Smokers should be encouraged to access counseling services.

  13. 1: Infections in pregnant women.

    Gilbert, Gwendolyn L

    Some infections are more serious in pregnant than non-pregnant women because of the potential for vertical transmission to the fetus or infant (eg, varicella, rubella, cytomegalovirus infection, toxoplasmosis and listeriosis). Pre-pregnancy or routine antenatal screening for presence of, or susceptibility to, some of these infections and appropriate management can prevent adverse fetal or perinatal outcomes; screening should include rubella IgG, hepatitis B surface antigen, serological tests for syphilis and HIV antibody. If certain other vertically transmissible infections are suspected because of a positive antenatal test result, confirmatory tests for maternal and, if indicated, fetal infection are essential before intervention is considered (eg, cytomegalovirus infection). For some vertically transmissible infections that are not readily preventable, appropriate management of maternal infection can reduce fetal damage (eg, toxoplasmosis). PMID:11999241

    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.

    Paracoccidioidomycosis (PCM), caused by the dimorphic fungus Paracoccidioides brasiliensis (Pb), is the most prevalent systemic mycosis in Latin America. There are few reports in the literature about the disease damages during pregnancy and the consequences to the fetuses and breeding. This study evaluated the implications of PCM during pregnancy on offspring and mothers in Wistar rats. Groups of rats were submitted to systemic Pb infection, by intraperitoneal infusion, and mated 30 days after the infection date. Immediately after birth, rats and neonates were sacrificed to obtain organs for standard histological examination, morphometric analysis, fungi recovery by plating (CFU) and dosing of anti-Pb antibodies by ELISA. There were no stillbirths or miscarriages, however, the fetuses from infected pregnant rats had lower body and organ weight but the fertility rate was 100%. The largest number of CFU was recovered from the organ of pregnant rats, the pathological examination revealed more severe infection in the same group, further on the largest number of granulomas and fungal field. It can be concluded that the PCM was more severe in the group of pregnant rats, with implications to the weight of offspring.

    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.

    Objective. To assess the use of cell phones and email as means of communication between pregnant women and their gynecologists and family physicians. Study Design. A cross-sectional study of pregnant women at routine followup. One hundred and twenty women participated in the study. Results. The mean age was 27.4 ± 3.4 years. One hundred nineteen women owned a cell phone and 114 (95%) had an email address. Seventy-two women (60%) had their gynecologist's cell phone number and 50 women (42%) had their family physician's cell phone number. More women contacted their gynecologist via cell phone or email during pregnancy compared to their family physician (P = 0.005 and 0.009, resp.). Most preferred to communicate with their physician via cell phone at predetermined times, but by email at any time during the day (P < 0.0001). They would use cell phones for emergencies or unusual problems but preferred email for other matters (P < 0.0001). Conclusions. Pregnant women in the Negev region do not have a preference between the use of cell phones or email for medical consultation with their gynecologist or family physician. The provision of the physician's cell phone numbers or email address together with the provision of guidelines and resources could improve healthcare services. PMID:25132848

  20. Craving and Withdrawal Symptoms During Smoking Cessation: Comparison of Pregnant and Non-Pregnant Smokers.

    Berlin, Ivan; Singleton, Edward G; Heishman, Stephen J

    2016-04-01

    Although pregnant smokers are aware of the negative peri- and postnatal health consequences of smoking, the cessation rate in pregnancy is low, raising the question of why pregnant smokers have difficulty quitting. Reasons might be that pregnant smokers experience more intense craving and withdrawal symptoms than non-pregnant smokers. We compared craving and withdrawal in 306 pregnant smokers versus 93 non-pregnant women using data from two smoking cessation trials. Complete data were analyzed using pre-quit and post-quit (2 weeks after quit date) craving and withdrawal measured by the 12-item French Tobacco Craving Questionnaire (FTCQ-12) and French Minnesota Nicotine Withdrawal Scale (FMNWS). Pregnant smokers started smoking and smoked regularly earlier and succeeded far less at quitting smoking by week 2 than the general population of smokers (11% versus 43%). Post-quit date FTCQ-12 general score was higher in pregnant smokers compared to comparison groups, and was driven by elevated emotionality and expectancy. FMNWS decreased significantly less among pregnant smokers than among non-pregnant smokers. Insufficient reduction of craving and withdrawal symptoms in response to a quit attempt may partially explain why pregnant smokers may have more difficulty quitting than non-pregnant smokers. Because this was a historical comparison, findings are preliminary; however, they might foster further investigation of differences in craving and withdrawal symptoms in pregnant versus non-pregnant smokers.

    2014-01-01

    Background This study was undertaken to characterize the vaginal microbiota throughout normal human pregnancy using sequence-based techniques. We compared the vaginal microbial composition of non-pregnant patients with a group of pregnant women who delivered at term. Results A retrospective case–control longitudinal study was designed and included non-pregnant women (n = 32) and pregnant women who delivered at term (38 to 42 weeks) without complications (n = 22). Serial samples of vaginal fluid were collected from both non-pregnant and pregnant patients. A 16S rRNA gene sequence-based survey was conducted using pyrosequencing to characterize the structure and stability of the vaginal microbiota. Linear mixed effects models and generalized estimating equations were used to identify the phylotypes whose relative abundance was different between the two study groups. The vaginal microbiota of normal pregnant women was different from that of non-pregnant women (higher abundance of Lactobacillus vaginalis, L. crispatus, L. gasseri and L. jensenii and lower abundance of 22 other phylotypes in pregnant women). Bacterial community state type (CST) IV-B or CST IV-A characterized by high relative abundance of species of genus Atopobium as well as the presence of Prevotella, Sneathia, Gardnerella, Ruminococcaceae, Parvimonas, Mobiluncus and other taxa previously shown to be associated with bacterial vaginosis were less frequent in normal pregnancy. The stability of the vaginal microbiota of pregnant women was higher than that of non-pregnant women; however, during normal pregnancy, bacterial communities shift almost exclusively from one CST dominated by Lactobacillus spp. to another CST dominated by Lactobacillus spp. Conclusion We report the first longitudinal study of the vaginal microbiota in normal pregnancy. Differences in the composition and stability of the microbial community between pregnant and non-pregnant women were observed. Lactobacillus spp. were the

    2004-01-01

    A split-sample study was conducted to evaluate the performances of three enzyme immunoassays (EIAs) utilizing one or more conformational antigens to detect human parvovirus B19 (B19V)-specific immunoglobulin M (IgM) or IgG in the sera of 198 pregnant women. We compared EIAs available from Biotrin International, Inc. (Dublin, Ireland), Medac Diagnostika (Wedel, Germany), and Mikrogen (Martinsried, Germany). Specimens with discordant results were analyzed further using an immunofluorescence assay (Biotrin). Equivocal data accounted for close to half of all the discrepant results for both IgM and IgG, with 7 of 15 discrepant results from the Medac and Mikrogen kits involving equivocal data and the Biotrin kit giving a single equivocal result. For each specimen, a consensus was established from the four test results if agreement occurred among at least three of four results. Overall, the highest percentage of agreement with the consensus results was seen when Biotrin kits were used; 194 (100%) of 194 and 194 (99.5%) of 195 results for IgM and IgG, respectively, agreed with the consensus results. When Medac kits were used, 189 (97.4%) of 194 and 191 (97.9%) of 195 results for IgM and IgG, respectively, agreed with the consensus, and when Mikrogen kits were used, 179 (92.3%) of 194 and 193 (99%) of 195 results for IgM and IgG, respectively, agreed with the consensus. Given the consensus results, the Medac EIA appeared to generate presumed false-positive results for IgM and the Mikrogen EIA appeared to generate presumed false-positive results for IgG and IgM. In summary, the Biotrin EIAs produced far fewer equivocal results than the other assays and results of the Biotrin EIAs agreed more often with the consensus results than did those of the other commercially available EIAs for detecting B19V-specific IgM and IgG antibodies.

    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

    Courts and legislatures are increasingly being called upon to restrict the autonomy of pregnant women by requiring them to behave in ways that others determine are best for the fetuses they carry. The state should not attempt to transform pregnant women into ideal baby-making machines. Pregnant women make decisions about their behavior in the context of the rest of their lives, with all the attendant complexities and pressures. Our interest in helping future children by improving prenatal care would best be furthered by helping pregnant women to make informed, less constrained choices, not by punishing women or depriving them of choices altogether.

    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.

  11. Pregnancy zone protein analogue in pregnant and non-pregnant primates, and its decrease during pregnancy in some monkey species.

    Rabbit antiserum to human pregnancy zone protein (PZP) cross-reacted with analogous proteins in several species of primates. The chimpanzee PZP showed reactions of identity with human PZP, while the PZP analogue in the orangutan, in four species of old world monkeys (pig-tailed, rhesus, cynomolgus and stump-tailed) and in a species of new world monkey (squirrel) showed equivalent reactions of partial identity with human PZP. In the chimpanzee and orangutan, the PZP analogue was present in low concentrations in non-pregnant animals, but as in the human, it increased quite appreciably during gestation. In the chimpanzee, this increase in pregnancy was about four-fold greater than in the human. In sharp contrast, in the old and new world monkeys, the PZP analogue was present in much higher concentrations in non-pregnant animals than it is in humans. In addition, during pregnancy the PZP analogue in these monkey species actually decreased during pregnancy. In the few cases studied, normal levels were regained about 1 month after delivery. A normal plasma protein, alpha2-macroglobin, was also studied in these primate species, because this protein shares some characteristics with PZP. Analogous alpha2-macroglobulin serum proteins were found in all the primates tested, but the observed gel diffusion identity patterns suggested that this protein was phylogenetically older than PZP. alpha2-macroglobulin increased slightly during human pregnancy, but in all the other primates studied, the alpha-macroglobulin analogue was either unchanged or slightly decreased during gestation.

    Objective The purpose of this study was to compare the transcriptome of visceral and subcutaneous adipose tissues between pregnant and non-pregnant women. Study Design The transcriptome of paired visceral and abdominal subcutaneous adipose tissues from pregnant women at term and matched non-pregnant women (n = 11) was profiled with the Affymetrix Human Exon 1.0 ST array. Differential expression of selected genes was validated with the use of quantitative reverse transcription–polymerase chain reaction. 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

    This paper addresses common questions that clinicians face when treating pregnant women with opioid dependence. Guidance is provided to aid clinical decision-making, based on both research evidence and the collective clinical experience of the authors which include investigators in the Maternal Opioid Treatment: Human Experimental Research (MOTHER) project. MOTHER is a double-blind, double-dummy, flexible–dosing, parallel-group clinical trial examining the comparative safety and efficacy of methadone and buprenorphine for the opioid dependence treatment among pregnant women and their neonates. The paper begins with a discussion of appropriate assessment during pregnancy, and then addresses clinical management stages, including maintenance medication selection, induction and stabilization, opioid agonist medication management before, during and after delivery, pain management, breast-feeding, and transfer to aftercare. Lastly, other important clinical issues including managing co-occurring psychiatric disorders and medication interactions are discussed. PMID:18248941

    2014-06-15

    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.

    Trauma continues to be a leading cause of nonobstetric maternal and fetal mortality worldwide. Caring for the pregnant trauma patient requires a systematic and multidisciplinary approach. It is important to understand the anatomic and physiologic changes that occur during pregnancy. Accepted trauma guidelines for imaging and interventions should generally not be deviated from just because a patient is pregnant. Focus should be placed on injury prevention and education of at risk patients to decrease the morbidity and mortality associated with traumatic injuries in pregnant patients.

    There is much pressure on the airlines to allow stewardesses to fly while pregnant. Some of them want to fly in quite advanced stages of pregnancy. This paper offers a survey of the problem, the hazards that may occur and some guidelines for the physician. The author outlines the normal changes to be expected with advancing pregnancy and those factors that could have an adverse effect on a pregnant stewardess and her fetus, such as hypoxia, trauma, abortion, the hazards of travel, and flying itself. Certain legal problems of unemployment and medical disability also are discussed. Travel alone offers no real danger to the pregnant stewardess in the first trimester of pregnancy; however, because of the changing mechanics of her size, posture, and increasing unsteadiness, it would be wisest to require a pregnant stewardess to cease flying at 13 weeks, with an absolute prohibition of flying after the 20th week.

    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

    Serotonin (5-HT) can stimulate the cholinergic system of the uterus by indirect actions on the modulation of reflexes and a direct action on smooth muscles. We investigated the role of 5-HT in the regulation of the cholinergic activity in the uterine parts of non-pregnant rabbits. The right vagus or pelvic nerve and the left sympathetic trunk were stimulated by an electrical field, and the uterine contractile activity was evaluated by measuring the amplitude and frequency of slow wave electromyogram (EMG), with the surface of microelectrodes applied to the uterus bottom, body, and cervix, respectively. Double stimulation of the vagus or pelvic nerve and the sympathetic trunk increased the frequency and the amplitude of the slow wave EMG in all the uterine parts. Furthermore, the administration of exogenous 5-HT increased the vagus or pelvic induced EMG activity in all parts of the uterus. Overall our results demonstrate that 5-HT enhances the vagus contractile activity with a magnitude of the effect decreasing from the bottom to the cervix, whereas 5-HT enhances the pelvic nerve contractile functions with a magnitude of the response increasing from the bottom to the cervix. The administration of droperidol, a 5-HT3 and 4 receptor inhibitor, and spiperone, a 5-HT2 receptor antagonist, inhibited the effect of the serotoninergic fibers of the sympathetic trunk to increase the vagus and pelvic nerve EMG activity. These data suggest that 5-HT stimulation of the parasympathetic nerves results in the induction of uterine contraction via the activation of 5-HT2, 3, and 4 receptor subfamilies. PMID:24892885

    Tuberculosis (TB) is a significant contributor to mortality in HIV-infected patients. Concurrent TB infection is also a significant contributing factor to maternal mortality in human immunodeficiency virus (HIV)-infected pregnant women. Studies addressing the outcomes of TB and HIV co-infection among pregnant women are generally infrequent. Although limited, the records maintained by the Revised National Tuberculosis Control Programme (RNTCP) and the National AIDS Control Programme (NACP) in Karnataka State, Southern India provide information about the numbers of pregnant women who are co-infected with TB and HIV and their pregnancy outcomes. We reviewed the data and conducted this study to understand how TB-HIV co-infection influences the outcomes of pregnancy in this setting. We sought to determine the incidence and treatment and delivery outcomes of TB-HIV co-infected pregnant women in programmatic settings in Karnataka State in southern India. The study participants were all the HIV-infected pregnant women who were screened for tuberculosis under the NACP from 2008 to 2012. For the purposes of this study, the program staff in the field gathered the data regarding on treatment and delivery outcomes of pregnant women. A total of seventeen pregnant women with TB-HIV co-infection were identified among 3,165,729 pregnant women (for an incidence of 5.4 per million pregnancies). The median age of these pregnant women was 24 years, and majority were primiparous women with WHO HIV stage III disease and were on a stavudine-based ART regimen. The maternal mortality rates were 18% before delivery and 24% after delivery. The abortion rate was 24%, and the neonatal mortality rate was 10%. The anti-tuberculosis treatment and anti-retroviral treatment outcome mortality rates were 30% and 53%, respectively. Although the incidence of TB among the HIV-infected pregnant women was marginally less than that among the non-HIV-infected women, the delivery outcomes were relatively

    The purpose of the study was to test a model based on the product of value and belief, called expected utility (EU), on the addictive behaviour of smoking. A total of 40 pregnant and 40 non-pregnant women over a period of 2 weeks performed judgements on values and beliefs about consequences related to smoking for the conditions of continuing and stopping smoking. There were no differences between pregnant and non-pregnant women in the EU of smoking. Differences in expected utility between the conditions of continuing and stopping smoking were larger for health consequences compared with psychological and social consequences and consequences related to pregnancy. Expected utility gives a good description of judgements over time. Values as well as beliefs related to health consequences should be stressed in smoking cessation programmes, especially among pregnant women.

    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.

    Converging evidence indicates that pregnant women report experiencing problems with memory, but the results of studies using objective measures are ambiguous. The present study investigated potential reason(s) for the discrepancy between findings of subjective and objective memory deficits, as well as potential source(s) of pregnant women's problems with memory. Sixty-one pregnant and 24 nonpregnant women completed a series of memory tests which included field and laboratory measures of prospective memory. Three standardized questionnaires were used to assess subjective aspects of memory. The influence of cortisol, depressed mood, anxiety, physical symptoms, sleep/fatigue, and busyness on pregnancy-related deficits was also examined. The findings revealed objective pregnancy-related deficits on two of the field measures of prospective memory. Pregnancy-related subjective deficits were also detected on all of the questionnaires. In contrast, no objective pregnancy-related deficits were found on the laboratory measures of memory. Increased physical symptoms accounted for one of the objective deficits in memory, while depressed mood and physical symptoms accounted for two of the subjective memory deficits. Collectively, these findings suggest that pregnant women experience everyday life problems with memory that are not readily detected in the laboratory environment. The predominant use of laboratory tests may explain the myriad of previous failures to detect objective deficits in pregnant women's memory.

    Background Thrombocytopenia is a common problem during pregnancy that is not frequently detected and as a result is often inappropriately managed. The obvious concern with thrombocytopenia during pregnancy is the risk of significant bleeding at the time of delivery. This study was designed to determine the prevalence of gestational thrombocytopenia in pregnant women reporting for ante-natal care at a Ghanaian primary health care centre. Methods Platelet count was evaluated in 300 blood samples from pregnant women and 100 non pregnant female blood donors. The platelet counts were performed using Sysmex KX-21N automated hematology analyzer. The study design was cross sectional. Proportions were analyzed for statistical significance with the Chi square, Odds ratio was also calculated Results The prevalence of thrombocytopenia in pregnant women in this study was 15.3% compared with 4% in controls. This was statistically significant with a P value of 0.003. Odds ratio was 4.31 (95% CI: 1.52-12.04). Most cases of thrombocytopenia were mild (76%), only 4% of the women with thrombocytopenia had severe thrombocytopenia. Conclusion The frequency of thrombocytopenia in this study was higher than that reported from more developed parts of the world. This may be due to undetected malaria infection in our patients. Pregnant women should be routinely screened for thrombocytopenia. Those found to be thrombocytopenic should have both thick and thin blood films done to exclude the presence of malaria parasites.

    A pregnant patient presenting to interventional radiology (IR) has a different set of needs from any other patient requiring a procedure. Often, the patient's care can be in direct conflict with the growth and development of the fetus, whether it be optimal fluoroscopic imaging, adequate sedation of the mother, or the timing of the needed procedure. Despite the additional risks and complexities associated with pregnancy, IR procedures can be performed safely for the pregnant patient with knowledge of the special and general needs of the pregnant patient, use of acceptable medications and procedures likely to be encountered during pregnancy, in addition to strategies to protect the patient and her fetus from the hazards of radiation.

    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.

    The objective of this study was to provide trained labor support (doulas) to pregnant women in jail. A multiagency intervention project provided doula birth services to pregnant women in urban jails. Program evaluation included interviews with women and written satisfaction surveys of providers and correctional officers. A convenience sample of 18 incarcerated women received doula services. A doula visited each woman in jail antepartum to review expectations for labor and birth; during hospitalization, the doula provided continuous support throughout labor and birth. Doulas visited women postpartum to review birth events. Surveys administered to providers and officers demonstrated high satisfaction with the program. Qualitative interviews with 14 women indicated unanimous support for the services and documented women's major concerns. Findings support offering doula services to all pregnant women in custody and expanding doula services to include early and comprehensive intervention coordinated by nurses.

    The authors describe, for the first time, bilateral, sequential large dacryocystoceles during pregnancy and review the literature for this presentation. A 26-year-old, 15-week pregnant woman presented with OD epiphora, diplopia, and pain in the setting of an inferomedial orbital mass. Surgical exploration and histopathology were consistent with a dacryocystocele, and a dacryocystorhinostomy was curative. She returned at 34-week gestation, with an identical presentation on the left side. Review of the literature reveals that dacryocystoceles occasionally present in adults; however, bilateral involvement may be unusual. Bilateral dacryocystoceles have not been previously reported in a pregnant woman.

    From among 4200 chemical compounds contained in the tobacco smoke, nicotine and carbon monoxide are responsible for changes in the heart-vessel system to the greatest extent. Additionally, other toxic compounds, including the carcinogenic ones, have a significant impact on the biological activity in the tissues of blood vessels. A particularly complex picture of the detrimental impact of the tobacco smoke is presented in case of pregnant women, fetuses and newborns. The aim of the research was to assess the impact of tobacco smoke on the permeability of capillaries in different tissues of rats (lungs, brain, liver, kidneys) and testing of the potentially protective impact of rutine (3-rutinozide of quercetin). The research on the permeability of capillaries has been carried out applying Evans blue. The animals were divided into 8 research groups: pregnant animals--"control", "rutine", "tobacco smoke", "rutine+tobacco smoke", and non-pregnant animals--"control", "rutine", "tobacco smoke", "rutine+tobacco smoke". In the first stage of research (pregnant, non-pregnant-- groups: "rutine" and "rutine+tobacco smoke"), the water rutine solution in a dose of 40 mg/kg of body weight was administered. The non-pregnant and pregnant animals from groups "tobacco smoke" and "rutine+tobacco smoke" were exposed to tobacco smoke via inhalation (1500 mg CO/m3 of air) for 21 days. All the animals were injected with the water Evans blue solution in a dose of 30 mg/kg of body weight. After 30 minutes, the animals were killed by cutting the abdominal aorta, and lungs, brain, liver and kidneys were taken for further testing. The cotinine in the urine was determined by the HPLC method, using norephedrine as the internal standard, after the preceding extraction by means of the liquid-liquid technique. The concentration of cotinine in case of non-pregnant and pregnant females was respectively 11.8 +/- 1.9 pg/ml of urine and 12.0 +/- 2.5 microg/ml of urine. In case of the rats, which

    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.

    Tissue distribution studies of human activated protein C (CAS 42617-41-4, APC) were performed in mice after single or repeated administration, and placental transfer and milk passage study were investigated. At 15 min after a single intravenous administration of 125I-APC, radioactivity was mainly distributed to the blood and blood rich organ, such as liver, and then rapidly eliminated. The radioactivity distributed to tissues was almost negligible at 24 h after administration except for the thyroid. The qualitative study of the distribution of radioactivity to tissues by whole body autoradiography demonstrated the correspondence to the result of the quantitative assay of distribution of radioactivity after single administration of 125I-APC. The influence of repeated administration of APC on its pharmacokinetic disposition was studied by administering 125I-APC once a day to mice for 14 days. Though plasma radioactivity at 15 min in mice during repeated administration of 125I-APC was almost similar to that at 15 min after a single administration, the radioactivity at 24 h after administration was 2 times higher than that after a single administration. The profile of plasma radioactivity during and after repeated administration corresponded to the simulation curve which was described with the pharmacokinetic parameters obtained previously after the single administration. Distribution profile after repeated administration at 15 min after the 4th, 7th, 10th and 14th administration was almost similar to that at 15 min after a single administration except for the thyroid and spleen. In the thyroid, the radioactivity was 500 times higher than that after a single administration, and HPLC analysis demonstrated that the radioactivity was attributed to thyroglobulin. As to the spleen, the radioactivity was about 52% of that after a single administration. During the repeated administration, the spleen became larger than that after a single administration and the final weight

    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.

    Bisphenol A is a chemical that is present in a number of products and types of food packaging. Prenatal exposure to bisphenol A may cause behavioural changes in young children. The aim of this study was to investigate exposure to bisphenol A in pregnant Australian women as a surrogate of neonatal exposure. First morning void urine samples were collected from 26 pregnant women at around week 38 of gestation. Bisphenol A was detectable in 85% of the samples analysed. The median concentration in this group of women was 2.41μg/L with a range of pregnant women have measured biological concentrations of urinary bisphenol A similar to those reported for pregnant women in other developed countries. Given the potential impacts of prenatal bisphenol A exposure, further research in this area is warranted.

    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

  10. Ethical challenges of treating the critically ill pregnant patient.

    Most ethical issues in obstetrics, both in the critical care and non-emergency situations, hinge around the maternal-fetal relationship. With access to the necessary information and support, most women strive to improve their chance of having healthy babies. However, there could be situations where their interests do not correspond with fetal interests, thereby giving rise to conflict situations. At the centre of the debate about a possible conflict is the notion of the fetus as a patient. A pregnant woman's autonomy and informed refusal should be respected. Where she is not competent to make an informed decision, proxy consent should be obtained or the doctrine of substituted judgement be applied. A decision to withhold or withdraw treatment in the intensive care unit (ICU) should only occur once a definitive diagnosis of terminal illness is made. Standards for the management of the human-immunodeficiency-virus-positive woman in the obstetric ICU situtation should be no different from standards employed to manage a critically ill pregnant patient in ICU with a chronic medical disease.

    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

    The aim of the study was to determine the distribution of different volumes of methylene blue solution injected into the epidural space in anaesthetized pregnant and non-pregnant sheep, to evaluate its cranial distribution and to compare between them. Fifteen pregnant and fifteen non-pregnant sheep were included in the study. Sheep were anaesthetized and received 0.05, 0.1, or 0.2 mL/kg of a lumbosacral epidural solution containing 0.12% methylene blue in 0.9% saline. Thirty minutes after the epidural injection, the ewes were euthanized. The extension of the dye within the epidural space was measured, and the correlation between the volume of the dye injected and the number of stained vertebrae was evaluated. The cranial migration of the dye between pregnant and non-pregnant sheep was also compared. The results show that the volume of methylene blue injected epidurally into pregnant and non-pregnant sheep correlated directly with its cephalic distribution into the epidural space; and a volume of 0.1 mL/kg or 0.2 mL/kg stained up to the first lumbar segment in pregnant and non-pregnant sheep, respectively. Also, the results suggest that the volume of drugs administered into the epidural space of pregnant sheep should be half the volume that would be used in non-pregnant sheep. PMID:24709655

    Background: Q fever is a zoonotic disease caused by Coxiella burnetii. There is no information about this disease in pregnant women in Iran. The aim of this study was to investigate the seroprevalence of C. burnetii infection among pregnant women in southwestern (Ahvaz) and northern (Parsabad) Iran and further to comparison its prevalence in normal and abnormal pregnancies. Methods: A total of 400 samples were collected randomly from pregnant women who referred to diagnostic laboratories of Ahvaz and Parsabad in 2014. An indirect ELISA kit, designed in Veterinary Faculty, was used to detect the specific antibodies against phase II humanC. burnetii in serum samples. Results: The overall prevalence of C. burnetii in sera from pregnant women was 29.3% (95% confidence interval (CI): 25–34%). The prevalence of C. burnetii infection was significantly different in Ahvaz and Parsabad with, respectively, 22 (95% CI: 16–28%) and 36.5% (95% CI: 30–43%). Total prevalence of C. burnetii infection in serum was significantly higher in women with abnormal pregnancy history (39.8%) compared with normal pregnancies (23.8%). Furthermore, maternal age had significant association with seropositivity and the prevalence increased with maternal age. This could be due to higher probability of encountering C. burnetii in older women. Conclusion: The present study demonstrated ahigh seroprevalence of C. burnetii infection among pregnant women in Iran for the first time. Seropositivity was associated with adverse pregnancy outcomes and maternal age. The pregnant women who experienced abnormal pregnancy had higher seroprevalence of C. burnetii compared to women with normal pregnancy. PMID:27252922

  14. Medical risk: implicating poor pregnant women.

    1994-03-01

    Since 1987 the United States courts have increasingly relied on medical testimony to prosecute women labeled 'high risk' for failure to comply with medical advice when their fetuses or babies die. Drawing on fieldwork in a public prenatal clinic in Northern California, it is argued that risk does not represent scientific certainty. While the assessment and management of risk is not standardized or consistently applied in the clinic, health care providers and the legal system make decisions as if risk is unambiguous 'fact'. Consequently, labeling poor pregnant women 'high risk', implicitly and explicitly makes them accountable if they are unable to change their behavior as prescribed by health professionals. Through an examination of the dilemmas facing poor pregnant women seeking prenatal care, this paper suggests how attempts to prosecute women may discourage rather than encourage them to seek care. Overall, there is a need for understanding the complexities of risk and its usages in medical and legal settings.

It changes in accordance with the growth of the fetus in the womb and at the same time ensures health of the mother. One can find remnants of this dietics with midwives and older women, but a detailed and comprehensive diet plan is being practiced only by the vaidyas of the classical medical tradition. In this paper we are giving a broad expanse of the month wise diet, which can be modified according to the age, season, place, constitution and the digestive fire of the pregnant woman.

    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.

    Providing needed dental treatment, managing oral infection, and controlling pain are essential functions of dentists for helping patients maintain overall health during pregnancy. Medications commonly required for dental care consist of local anesthetics and associated vasoconstrictors, centrally and peripherally acting analgesics, sedative and anxiolytic agents, and antibiotics. Therapeutic drugs routinely used in dental practice are selected because of their known safety and effectiveness. However, for a pregnant patient requiring dental care, the agents routinely prescribed should be reevaluated for potential risks to the mother and/or fetus. The decision to administer a specific drug requires that the benefits outweigh the potential risks of the drug therapy. This article reviews and updates the recommendations for using dental therapeutic agents, thereby enabling general practitioners to select the safest drugs when treating pregnant dental patients.

    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.

It is rarely implicated in hemolytic transfusion reaction; however, it can lead to potentially severe transfusion reactions. Anti S is also capable of causing mild to severe fatal hemolytic disease of newborn. We report a case of anti S antibody in a pregnant patient with complicated falciparum malaria.

    Aim: To compare pregnant and non-pregnant females for vitamin D level and periodontal status and to determine if there is any association between the periodontal health and hypovitaminosis D in pregnant women. Materials and Methods: A cross-sectional study was conducted in Jhelum, Pakistan. Participants were pregnant females at ~ 12 weeks of gestation (n = 36) and non-pregnant (n = 35) females selected from the same locality. Periodontal parameters such as probing depth, bleeding on probing, and attachment loss were recorded. Serum samples were taken to measure blood indices and vitamin D levels. Chi-square test and Odds ratio were applied to determine the association between hypovitaminosis D and periodontal status. Results: Vitamin D deficiency was common in the pregnant group compared to non-pregnant (P < 0.001). Blood indices (hemoglobin, hematocrit, mean corpuscular volume) were significantly lower among the pregnant compared to the non-pregnant group (P < 0.001). However, there was no significant difference between the two groups for probing depth and attachment loss. Conclusions: Pregnant women were more deficient in Vitamin D than non-pregnant women. However, no association between low vitamin D levels and periodontal disease was seen in the studied population. PMID:27382540

    Work reported in this chapter describes the potential role of relaxin in resetting cardiovascular thresholds in pregnant rats. Relaxin, a polypeptide produced primarily by the ovary in pregnant animals in many species, is also produced in the brain. Exogenous administration of relaxin into the brain causes a profound drinking response which is negated by pretreatment with a specific monoclonal antibody to rat relaxin when the antibody is injected into the brain. Neutralizing the action of endogenous brain relaxin in pregnant rats also blocks the normal increase in drinking that is observed in rats at night during the second half of pregnancy. Relaxin acts through the forebrain angiotensin system at the level of the subfornical organ (an important interface between the blood, the brain and the cerebrospinal fluid) as blockade of the angiotensin II receptor action negates several central actions of relaxin. Expression of angiotensin II AT1 receptors in the subfornical organ increases in parallel with the increase in circulating relaxin seen in the second half of pregnancy. Neutralizing the effects of endogenous brain relaxin, using central injections of the monoclonal antibody, blocks this increase in the expression of angiotensin II AT1 receptors in subfornical organ. These data imply that relaxin in the brain may act to affect central cardiovascular thresholds in rats and this may be important for the normal physiology of pregnancy.

    Extramarital pregnancies among adolescent girl is not only an obstetrical, but also a socio-psychological problem. By use of special methods (questionnaires, a scala for gravity of psycho-social stress. Eysenck's [correction of Isenk's] test and self score diagnostic test), 63 adolescent pregnant girls were studied aged 13-16, of which 33 delivered and 30 terminated their pregnancies at will. Almost half of the girls were gypsies with little or no education and relatively healthy live style. In 70% of the cases family climate was saturated with conflicts. 48% of the pregnant girls accepted their pregnancy calmly, in 79% of the cases it was decided, 87% of the girls expected to marry the father of their children, and in 30% the children were left for adoption. 33% of the patient were victims of rape and had negative relationship towards their pregnancy. In 41% the pregnant women exhibited introversion and in 38%--extroversion and in those who delivered the ratio was almost the same In this same group moderate to intense stress was almost the rule, while among those who terminate their pregnancies light stress was observed. Neurotic tendencies among those who delivered was also observed, likely due to the reaction towards the process of difficult adaptation to the fact of the extramarital delivery. In the studied group we didn't observe extreme cases of social disadaptation reached crises of the pregnancy, abortion or delivery PMID:8743835

    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.

    Because of the high incidence of congenital syphilis at the University Teaching Hospital, Lusaka, Zambia, the potential risks of congenital infection and fetal loss due to syphilis were assessed by screening 202 antenatal patients, 340 pregnant women admitted to the hospital whose pregnancies ended in either spontaneous abortion or stillbirth, and 469 consecutive babies delivered at the hospital. Primary serological screening was performed with the rapid plasma reagin test, and reactive sera were confirmed by the Treponema pallidum haemagglutination test. In all cases detailed histories were obtained and patients were examined for clinical signs of syphilis. The TPHA test result was reactive in 12.5% of antenatal patients and in 42% of women who aborted in the later half of pregnancy. Among 469 consecutive babies delivered at the hospital, 30 had reactive results to the TPHA test; of these two were stillborn and four had signs of congenital syphilis at birth.

    Cell-free fetal DNA in maternal circulation is higher during preeclampsia. It is unclear whether it is the cause or the consequence of the disease. The aim of this study was to prove whether injected rat fetal DNA induces preeclampsia-like symptoms in pregnant Wistar rats. They received daily i.p. injections of water or rat fetal DNA (400 μg) from gestation day 14 to 18. Blood pressure, proteinuria, placental and fetal weight were measured at gestation day 19. Plasma DNase activity, proteinuria and creatinine clearance were assessed. There was no significant difference in any of the measured parameters. The results of this study do not confirm the hypothesis that fetal DNA might induce preeclampsia. This is in contrast to others using human fetal DNA in mice. Further studies should be focused on the effects of fetal DNA from the same species protected from DNase activity.

    Protein turnover was studied in nine non-pregnant (NP) women, eight pregnant (P) and two gestational diabetic (GDM) women. Whole body protein turnover, synthesis and catabolism rates were measured using a single oral dose of /sup 15/N-glycine followed by measurement of enrichment of urinary ammonia. Urinary 3-methylhistidine (3MH) excretion was measured for three consecutive days, including the day of the protein turnover study. Whole body protein turnover and synthesis rates did not differ between the P and NP women, although the synthesis rates tended to be higher in the P group. Gestational diabetic women appeared to have considerably higher rates of both turnover and synthesis. Pregnant women excreted significantly more urinary 3MH than did non-pregnant women. GDM women appeared to have lower 3MH excretion than the P women. Correlation between 3MH excretion and protein turnover rates was nearly significant (p = .06) in the NP women, but was poorly correlated (p = .43) in the P women, suggesting that muscles may be a less important site of whole body protein turnover in pregnancy than in the non-pregnant state.

    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.

    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.

    In their work in human services organizations and community agencies across service sectors, social workers encounter pregnant and postpartum women experiencing mental health challenges. This article offers an evidence-informed Decision Support Guide designed for use by social workers working with pregnant and postpartum women who are struggling with complicated decisions about psychiatric medication use. The guide is built on contemporary notions of health literacy and shared decision making and is informed by three areas: (1) research into the lived experiences of pregnant and postpartum women and health care providers around psychiatric medication decision making, (2) a critical review of existing decision aids, and (3) feedback on the strategy from social work practitioners who work with pregnant and postpartum women. Emphasizing the relational nature of social work in supporting effective health-related decision making, the guide relies on maintaining a collaborative practice milieu and using a decision aid that engages clients in discussions about mental health during and around the time of pregnancy. The guide offers social workers a practice tool to support responsive and compassionate care by embracing their roles in problem solving and decision making, providing emotional and psychosocial support, and making appropriate referrals to prescribers.

    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.

    The care of pregnant travelers requires clinical information and skills that are derived from many disciplines. Issues to be considered include the safety of both mother and fetus during commercial air travel, vigorous exercise, scuba diving, and even high-altitude trekking. Immunizations require a balanced approach to the risk of disease versus the risks of vaccine complications. Safe or treated water sources are of paramount importance to prevent unnecessary exposure to antimicrobial and antiparasitic agents during pregnancy. Malaria prophylaxis is made even more difficult by an increasingly widespread resistance of Plasmodium species to chloroquine.

Through clinical illustrations taken from a weekly analytical group, the developmental processes and resonances found in such groups are discussed, alongside the technical challenges they pose on the leader. The scant literature on this topic and how it impacts on the therapeutic space is reviewed from individual and group analytic literature. This paper then extends the figuration of groups as types of metaphorical maternal container (Foulkes, 1964). In particular, this view is developed using the concept of primary maternal preoccupation (Winnicott, 1956) and simultaneously challenged with that of enclaves (O'Shaughnessy, 1992).

    2014-11-01

    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.

    The metabolism and disposition of a suspected human teratogen, trimethadione (TMO), was studied in pregnant rats following administration of the drug at doses of 60 and 240 mg/kg/day during 6 to 15 days of gestion, with a view to understanding the fetotoxicity of the drug. Following the last dose, animals were sacrificed at 6, 12, and 24 hr, and the fetuses were removed by caesarean section. The concentrations of TMO and its N-demethylated metabolite, dimethadione (DMO), were determined by a specific GLC procedure in maternal plasma, urine, brain, and liver, as well as in placenta and whole fetus. The plasma and liver concentrations of TMO and DMO suggested that the parent drug is rapidly converted to DMO. Total 24 hr urinary recoveries of the unchanged drug and the metabolite were 61 and 82% following 240 and 60 mg/kg/day doses of TMO, respectively. The DMO concentrations in brain and all other tissues analyzed were far greater than those of TMO. The fetus to maternal plasma concentration ratios of TMO suggested that the placental transfer of the drug was greater than the clearance from the fetus over the periods examined, whereas the transfer of the metablite seemed to be independent of dose. Furthermore, the rate of decline of DMO in fetus was far slower than that of the placenta and maternal plasma, causing accumulation of DMO in the fetus. The results suggest that the fetotoxic effects produced by TMO when given to pregnant rats could be due to accumulation of DMO in fetus.

  6. Achieving Body Weight Adjustments for Feeding Status and Pregnant or Non-Pregnant Condition in Beef Cows

    Background Beef cows herd accounts for 70% of the total energy used in the beef production system. However, there are still limited studies regarding improvement of production efficiency in this category, mainly in developing countries and in tropical areas. One of the limiting factors is the difficulty to obtain reliable estimates of weight variation in mature cows. This occurs due to the interaction of weight of maternal tissues with specific physiological stages such as pregnancy. Moreover, variation in gastrointestinal contents due to feeding status in ruminant animals is a major source of error in body weight measurements. Objectives Develop approaches to estimate the individual proportion of weight from maternal tissues and from gestation in pregnant cows, adjusting for feeding status and stage of gestation. Methods and Findings Dataset of 49 multiparous non-lactating Nellore cows (32 pregnant and 17 non-pregnant) were used. To establish the relationships between the body weight, depending on the feeding status of pregnant and non-pregnant cows as a function of days of pregnancy, a set of general equations was tested, based on theoretical suppositions. We proposed the concept of pregnant compound (PREG), which represents the weight that is genuinely related to pregnancy. The PREG includes the gravid uterus minus the non-pregnant uterus plus the accretion in udder related to pregnancy. There was no accretion in udder weight up to 238 days of pregnancy. By subtracting the PREG from live weight of a pregnant cow, we obtained estimates of the weight of only maternal tissues in pregnant cows. Non-linear functions were adjusted to estimate the relationship between fasted, non-fasted and empty body weight, for pregnant and non-pregnant cows. Conclusions Our results allow for estimating the actual live weight of pregnant cows and their body constituents, and subsequent comparison as a function of days of gestation and feeding status.

    This study investigated the expression and function of transient receptor potential vanilloid type-3 ion channels (TRPV3) in uterine radial arteries isolated from non-pregnant and twenty-day pregnant rats. Immunohistochemistry (IHC) suggested TRPV3 is primarily localized to the smooth muscle in arteries from both non-pregnant and pregnant rats. IHC using C' targeted antibody, and qPCR of TRPV3 mRNA, suggested pregnancy increased arterial TRPV3 expression. The TRPV3 activator carvacrol caused endothelium-independent dilation of phenylephrine-constricted radial arteries, with no difference between vessels from non-pregnant and pregnant animals. Carvacrol-induced dilation was reduced by the TRPV3-blockers isopentenyl pyrophosphate and ruthenium red, but not by the TRPA1 or TRPV4 inhibitors HC-030031 or HC-067047, respectively. In radial arteries from non-pregnant rats only, inhibition of NOS and sGC, or PKG, enhanced carvacrol-mediated vasodilation. Carvacrol-induced dilation of arteries from both non-pregnant and pregnant rats was prevented by the IKCa blocker TRAM-34. TRPV3 caused an endothelium-independent, IKCa-mediated dilation of the uterine radial artery. NO-PKG-mediated modulation of TRPV3 activity is lost in pregnancy, but this did not alter the response to carvacrol.

  8. Symptom control in the pregnant cancer patient.

    While much attention has been devoted to cytotoxic drugs and radiation therapy in the pregnant cancer patient, the drugs used for management of symptoms and complications related to cancer during pregnancy have been overlooked. There is substantial overlap between the symptoms of cancer and cancer management and the symptoms related to pregnancy. The mainstay of symptom management is drug therapy and the potential for a drug to be embryotoxic or teratogenic depends on when it is given. In general, drugs not proven safe in pregnancy should be withheld, especially during the first trimester. The few drugs that have been proven to be teratogenic are alcohol, thalidomide, the folic acid antagonists (which includes methotrexate), diethylstilbestrol, and the vitamin A isomers, but there is a good deal of uncertainty about many other therapeutic agents. Placental transport of drugs from mother to fetus must be taken into consideration from the fifth week of gestation to parturition. Although the first trimester is the time of most organ development in the fetus, the brain continues to develop throughout pregnancy and may be damaged later in pregnancy, resulting in diminished intelligence or behavioral problems. This review will focus on the treatment of the most common symptoms of cancer in a pregnant patient and the potential for fetal damage. PMID:11130478

    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.

  10. Identifying and helping battered pregnant women.

    This article highlights strategies in identifying and helping battered pregnant women. Studies report that 40-60% of battered women were abused during pregnancy inflicted in the form of blows to the abdomen, injuries to the breasts and genitals, and sexual assault. Because battering during pregnancy has been a prevalent occurrence, assessment during prenatal visits is most critical. This paper outlines several assessment approaches in dealing with battered pregnant women in specific circumstances, giving important consideration to her safety due to the potential risk of homicide. A Danger Assessment tool is utilized in assessing for potential homicide. Intervening with victims of abuse is difficult. The role of the nurse is to assist in the development of problem-solving and decision-making skills while the woman is still in extreme confusion or feeling of conflicting loyalties. Routine assessment for physical and sexual abuse during the prenatal period is recommended in order to prevent further abuse thus promoting maternal-child well being. PMID:2056861

    Human parvovirus B19 is a very common viral infection especially in school-aged children. The infection during pregnancy can affect the fetus due to lack of mother's immunity. Although, there is still no evidence of fetal teratogenic effects with parvovirus B19, but non-immune fetal hydrops and abortion may be caused by vertical transmission of the virus during pregnancy. This study was aimed to assess the prevalence of parvovirus B19-specific antibody (IgM) in pregnant women who had a spontaneous abortion. This cross-sectional study was carried out in all pregnant women who referred due to a spontaneous abortion. All demographic information such as age, occupation, and gestational age, last history of abortion, gravity, and presence of children below the age of six was recorded and a blood sample was provided for all the women. Then, the blood samples were tested to assay parvovirus B19-specific antibody (IgM) by EuroImmune ELISA kit. Among 94 pregnant women with the mean age of 28.4 years who had a spontaneous abortion, parvovirus B19 specific antibody (IgM) was detected in 17 participants (18.1%). Meanwhile, 14 women (14.9%) were suspected for presence of the antibody in their blood sample. There was no significant difference between the presence of antibody and age of pregnant women, occupation, gestational age, number of previous abortion, presence of children below the age of six and number of pregnancy. These findings revealed that a high percentage of pregnant women are probably non-immune against parvovirus B19, and also there might be a number of spontaneous abortions in which parvovirus infection caused fetal death.  However, more studies are needed to prove the absolute role of parvovirus B19 in these abortions.

    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. PMID:26658057

  18. Sustained increases in plasma C-type natriuretic peptides fail to increase concentrations in cerebrospinal fluid: Evidence from pregnant sheep.

    2015-07-01

    C-type natriuretic peptide (CNP) is a paracrine growth factor with high abundance in CNS tissues and cerebrospinal fluid (CSF). Consistent with findings of CNP transcripts in the cerebral microvasculature and hypothalamus, CNP increases the permeability of the blood-brain barrier and reduces food intake when administered intracerebroventricularly in rodents. Whether high concentrations of CNP in plasma can affect CSF levels is unknown. Accordingly we have studied changes (days 4, 87 and 116) in concurrent plasma and CSF concentrations of CNP peptides in pregnant sheep - a physiologically unique setting in which plasma CNP is elevated for prolonged periods. Preliminary studies in non pregnant sheep showed stable CNP levels in CSF during repetitive sampling. Compared with values in non pregnant controls, plasma concentrations of CNP peptides were markedly raised (30-fold) at days 87 and 116 in pregnant sheep, yet CSF levels in the two groups did not differ. CNP peptides in CSF decreased from day 4 to day 87 in pregnant sheep, possibly reflecting an adaptive response of the cerebral vasculature to increased hemodynamic load. We conclude that sustained high concentrations of CNP - far exceeding levels encountered in human pathophysiology - fail to affect CNP peptide levels in CSF.

    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.

    Pregnant women bear the greatest burden of malaria-human immunodeficiency virus co-infection. Previous studies suggest that interaction with antiretroviral drugs may compromise antimalarial pharmacokinetics and treatment outcomes. We conducted a preliminary clinical study to assess quinine pharmacokinetics in Malian pregnant women with acute malaria who reported taking nevirapine-based antiretroviral therapy. Of seven women, six had stable concentrations of nevirapine in the plasma and one had none. Quinine concentrations were lower, and its metabolite 3-hydroxyquinine higher, in the six women with nevirapine than in the one without, and quinine concentrations were below the recommended therapeutic range in 50% of the women. This preliminary observation warrants further research to understand the impact of long-term antiretroviral therapy on the treatment of acute malaria.

    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.

    There are numerous studies which examine the disposition of theophylline from a traditional point of view. Information about the behaviour of drugs, including theophylline, is, however, very scarce when investigating the kinetics by means of a physiological flow model. This study is concerned with the development of a predictive analytical model for the pharmacokinetics of theophylline in nonpregnant and pregnant rats. This model postulates that specific organ or tissue masses may be simulated by compartments whose elements have physiological properties, e.g., tissue volumes, blood flow, and metabolic activity. A model has been developed that has blood, brain, hepatic, muscular, pulmonary, renal, and fetal tissues. With few exceptions, the agreement was good between predicted and calculated tissue data in the pregnant and nonpregnant rats. Finally, model simulations were performed to investigate the impact of different pulmonary extraction ratios on the concentration-time profile of theophylline in a "hypothetical" human patient.

    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

    Prostaglandin or prostaglandin analogues have been shown to be luteolytic in the pregnant goat. In this study the temporal changes in the plasma concentrations of progesterone during pregnancy and after administration of PGF2a to pregnant goats are described. PGF2a administration to pregnant goats at 30 and 65 days after breeding induced abortion within 34 to 75 hours. These abortions were accompanied by estrus and profuse muco-hemorrhagic discharges. When PGF2a was administered to pregnant goats 140 or 142 days after breeding, premature parturition occurred within 42 to 76 hours. Live kids were delivered in all cases. The plasma levels of progesterone in all pregnant goats showed dramatic decreases within 24 hours after the prostaglandin injections and continued to decrease gradually until abortions or premature parturition. Thereafter, the progesterone levels remained low for several days. PMID:16725398

    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)

    Background: Thrombocytopaenia is a common haematologic abnormality during pregnancy. Pregnant women with thrombocytopenia have a higher risk of bleeding excessively during or after childbirth, particularly if they need to have a caesarean section or other surgical intervention during pregnancy, labour or in the puperium. The aim of this study was to determine the prevalence of gestational thrombocytopaenia among pregnant women reporting for antenatal care at tertiary health care centres in Lagos. Materials and Methods: Platelet count was analyzed in 274 consecutive pregnant women who gave informed consent and 70 non-pregnant female staff of the hospitals. Platelet count was performed on each sample using the Sysmex KN-21N automated haematology analyzer. The study design was cross-sectional, proportions were analyzed for statistical significance with the chi-square, and Odds ratio was also calculated. Thrombocytopaenia is classically defined as a platelet count of less than 150 × 109/L.34 Counts from 100 to 150 × 109/L are considered mildly depressed, 50 to 100 × 109/L are moderately depressed and less than 50 × 109/L are severely depressed. Results: Thirty-four (13.5%) pregnant women were thrombocytopaenic compared with three (4.3%) non-pregnant women. This was statistically significant; P = 0.03; Odds ratio: 3.5 (95% CI 1.03-11.82). Out of the 37 pregnant women who were thrombocytopaenic, most of them (78%) had mild thrombocytopenia, only 6% had severe thrombocytopaenia. Conclusion: The prevalence of gestational thrombocytopaenia in this study was 13.5%. Although majority of the pregnant women had mild thrombocytopaenia, healthcare providers should screen all pregnant women routinely for thrombocytopaenia to avoid excessive bleeding during or after childbirth.

    While female sex is a robust risk factor for posttraumatic stress disorder (PTSD), pregnant women are an understudied population in regards to PTSD symptom expression profiles. Because circulating hormones during pregnancy affect emotionality, we assessed whether pregnant women would have increased expression of the intermediate phenotypes of hyperarousal and fear-potentiated startle (FPS) compared to non-pregnant women. We examined PTSD symptom profiles in pregnant (n=207) and non-pregnant women (n= 370). In a second study, FPS responses were assessed in 15 pregnant and 24 non-pregnant women. All participants were recruited from the obstetrics and gynecology clinic at a public hospital serving a primarily African-American, low socioeconomic status, inner-city population. Our results indicate that overall PTSD symptoms were not different between the groups of women. However, pregnant women reported being more hypervigilant (p=0.036) than non-pregnant women. In addition, pregnant women showed increased FPS to a safety signal compared to non-pregnant women (p=0.024). FPS to a safety signal in pregnant women was significantly correlated with PTSD hyperarousal symptoms (r=0.731, p<0.001). Furthermore, discrimination between danger and safety signals was present in non-pregnant women (p=0.008), but not in pregnant women (p=0.895). Together, these data suggest that pregnant women show clinical and psychophysiological hyperarousal compared to non-pregnant women, and support screening for PTSD and assessment of PTSD risk in pregnant women.

    Non-immune pregnant women are at risk of severe measles. As the measles vaccination is contraindicated during pregnancy, women should be vaccinated before conception or during the postpartum period. Nevertheless, measles serology is not recommended during pregnancy in France, and there are no data available concerning measles susceptibility and its associated risk factors among pregnant women. The socio-demographic determinants of measles seronegativity have been identified in a prospective cohort of 826 pregnant women in Paris, France. Measles seronegativity was 10.41% (95% CI 8.32-12.50). Women from higher socio-economic groups, born in France after 1980, were more frequently seronegative.

    Urinary system stones can be classified according to size, location, X-ray characteristics, aetiology of formation, composition, and risk of recurrence. Especially urolithiasis during pregnancy is a diagnostic and therapeutic challenge. In most cases, it becomes symptomatic in the second or third trimester. Diagnostic options in pregnant women are limited due to the possible teratogenic, carcinogenic, and mutagenic risk of foetal radiation exposure. Clinical management of a pregnant urolithiasis patient is complex and demands close collaboration between patient, obstetrician and urologist. We would like to review current diagnosis and treatment modalities of stone disease of pregnant woman.

    Adolescent parenthood reduces the opportunities and optimal outcomes for both mother and child, yet pregnant teenagers rarely consider adoption. This paper reports a qualitative study that explored the reasons this option is so rarely examined. Twenty-one unmarried pregnant adolescents and their significant others were interviewed twice to determine the meaning adoption has for them. Four phenomena were found to be pivotal to the their willingness to consider adoption: (1) societal sanctions, (2) low level of knowledge, (3) anticipated psychological discomfort, and (4) lack of support from helping professionals. Information generated should be useful at health and social policy levels as well as to professionals who work with pregnant teenagers. PMID:8266842

    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.

    Hodgkin lymphoma (HL) presenting in patients with co-incidental advanced age, pregnancy, or human immunodeficiency virus (HIV) infection is uniquely challenging to manage. In this article we integrate recent evidence and clinical expertise to present recommendations for diagnosis and therapeutic management. Older patients with HL need to be carefully evaluated for comorbidies after which judicious choice of chemotherapy should minimize functional compromise. A pregnant patient with concurrent HL should be staged with minimal use of imaging requiring ionizing radiation and treated in an individualized manner optimally combining the strategies of treatment deferral when appropriate, use of single-agent vinblastine for symptomatic disease and reservation of multi-agent chemotherapy for the small minority of patients with aggressive clinical presentation. Treatment of HL coincident with HIV infection requires a combination of highly active anti-retroviral agents (HAART), standard multi-agent chemotherapy with meticulous attention to drug-drug interactions, and vigorous supportive care to ensure the best chance of cure.

    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.

    Recently, we showed that following pregnancy and 6 months of lactation, adolescents cease linear growth and have reduced fat and lean mass in rural Bangladesh. Here, we examined whether these changes varied by pregnancy outcomes such as fetal loss, low birthweight (LBW) and neonatal mortality. Anthropometric measurements were taken among 12-19-year-old primigravidae (n = 229) in early pregnancy and at 6 months post-partum. Never-pregnant adolescents (n = 456) matched on age and time since menarche were also measured at the same time. Change in anthropometry among pregnant vs. never-pregnant adolescents was compared by pregnancy outcome adjusting for confounders using mixed effects regression models. Pregnant girls, irrespective of birth outcome, did not gain in stature, while never-pregnant girls increased in height by 0.36 +/- 0.04 cm year(-1) (P < 0.05). Body mass index, mid-upper arm circumference (MUAC) and % body fat among pregnant adolescents whose infants survived the neonatal period had decreased at 6 months post-partum, whereas those who experienced a fetal loss or neonatal death did not change in any of the measurements. Consequently, the difference in change in ponderal size and body composition measures between pregnant and never-pregnant girls was higher among those whose neonates survived vs. those who experienced a fetal loss/neonatal death (BMI: -0.64 +/- 0.11 vs. 0.01 +/- 0.16 kg m(-2) year(-1); MUAC: -0.96 +/- 0.12 vs. -0.35 +/- 0.17 cm year(-1), both P < 0.05). LBW and preterm birth did not have a similar effect modification. Linear growth ceased among pregnant girls regardless of birth outcome. Maternal weight loss and depletion of fat and lean mass at 6 months post-partum were more pronounced when the infants survived through the neonatal period. PMID:20055928

    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.

    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

    Little is known about herpesvirus and putative periodontopathic bacteria in maternal chronic periodontitis. The present case-control study aimed to explore the potential relationship between putative periodontopathic bacteria and herpesviruses in maternal chronic periodontitis.Saliva samples were collected from 36 pregnant women with chronic periodontitis (cases) and 36 pregnant women with healthy periodontal status (controls). 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

  2. Motor activity of pregnant tethered sows.

    Continuous recording of body postures (standing or lying) using photocells connected to an event recorder was carried out on 125 pregnant sows tethered either by a thoracic girth or by a neck harness in six different farms, at different times of the year. Standing activity occupied an average of 250 min per day. This position occurred mainly during daytime, with amount of standing during the night (10 p.m. to 6 p.m.) averaging less than 2% of the total time. This mean value was found in 4 farms out of 6. However, on one farm, standing postures lasted 390 min and this hyperactivity was associated with stereotypes. In another farm, time spent standing did not exceed 180 min. In all cases, multiparous sows spent about 60% more time standing than first or second litter sows. Time spent standing was dependent on other animal characteristics such as physical condition and foot condition, and also on environmental factors. Activity rhythms were synchronized by food distribution. These results are discussed together with the potential of using motor activity to characterize adaptability of sows to tethering.

  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.

  4. Treatment of acne vulgaris in pregnant patients.

    2013-01-01

    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.

    Introduction Pyelonephritis is usually caused by ascent of bacteria (most often Escherichia coli) from the bladder, and is more likely in people with structural or functional urinary tract abnormalities. The prognosis is good if pyelonephritis is treated appropriately, but complications include renal abscess, renal impairment, and septic shock. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of antibiotic treatments for acute pyelonephritis in non-pregnant women with uncomplicated infection? We searched: Medline, Embase, The Cochrane Library, and other important databases up to November 2013 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found four studies that met our inclusion criteria. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics (intravenous), antibiotics (oral), and antibiotics (switch therapy).

    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.

    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.

    Car accident simulations involving pregnant women are well documented in the literature and suggest that intra-uterine pressure could be responsible for the phenomenon of placental abruption, underlining the need for a realistic amniotic fluid model, including fluid-structure interactions (FSI). This study reports the development and validation of an amniotic fluid model using an Arbitrary Lagrangian Eulerian formulation in the LS-DYNA environment. Dedicated to the study of the mechanisms responsible for fetal injuries resulting from road accidents, the fluid model was validated using dynamic loading tests. Drop tests were performed on a deformable water-filled container at acceleration levels that would be experienced in a gravid uterus during a frontal car collision at 25 kph. During the test device braking phase, container deformation induced by inertial effects and FSI was recorded by kinematic analysis. These tests were then simulated in the LS-DYNA environment to validate a fluid model under dynamic loading, based on the container deformations. Finally, the coupling between the amniotic fluid model and an existing finite-element full-body pregnant woman model was validated in terms of pressure. To do so, experimental test results performed on four postmortem human surrogates (PMHS) (in which a physical gravid uterus model was inserted) were used. The experimental intra-uterine pressure from these tests was compared to intra uterine pressure from a numerical simulation performed under the same loading conditions. Both free fall numerical and experimental responses appear strongly correlated. The relationship between the amniotic fluid model and pregnant woman model provide intra-uterine pressure values correlated with the experimental test responses. The use of an Arbitrary Lagrangian Eulerian formulation allows the analysis of FSI between the amniotic fluid and the gravid uterus during a road accident involving pregnant women. PMID:26592419

    The purpose of this study was to investigate how advanced maternal age influences lifestyle, nutrient intake, iron status, and pregnancy outcomes in pregnant women. The subjects of this study were 112 pregnant women who were receiving prenatal care at gynecologists located in Seoul. The subjects were divided into two groups according to their ages: those over age 35 were the advanced age group of pregnant women (AP) and those under age 35 were the young age group of pregnant women (YP). General factors, nutrient intakes, iron status, and pregnancy outcomes of the two groups were then compared. It was found that 72.5% of the YP group and 51.2% of the AP group had pre-pregnancy alcohol drinking experience; indicating that the YP group had more pre-pregnancy alcohol consumption than the AP group (P < 0.05). The only difference found in nutrient intake between the two groups was their niacin intakes which were 16.83 ± 8.20 mg/day and 13.76 ± 5.28 mg/day, respectively. When gestational age was shorter than 38.7 weeks, the average infant birth weight was 2.95 ± 0.08 kg, and when gestational age was longer than 40 weeks, it averaged at about 3.42 ± 0.08 kg. In other words, as gestational age increased, infant birth weight increased (P < 0.0001), and when maternal weight increased more than 15 kg, the infant birth weight increased significantly (P < 0.05). In conclusion, in order to secure healthy human resources, with respect to advanced aged women, it is necessary to intervene by promoting daily habits that consist of strategic increases in folate and calcium intake along with appropriate amounts of exercise.

    2010-09-15

    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. PMID:20655095

    The diagnosis of carcinoma of the breast during pregnancy poses a challenging dilemma. Although once regarded as incurable, recent reports reveal similar long term survival rates for pregnant and nonpregnant patients who have carcinoma of the breast. When referred to a surgeon, a pregnant woman with a suspicious mammary mass deserves an expedient histologic diagnosis; delay may jeopardize the chances of survival. Once the diagnosis is established, pregnant patients should be treated in a manner similar to nonpregnant patients because there is no evidence that carcinoma of the breast in pregnant women is biologically different than carcinoma of the breast in other premenopausal women. Fears of fetal exposure to radiation should not deter a physician from ordering appropriate preoperative diagnostic tests to stage the patients. Operation may be performed safely when general anesthesia is administered and postoperative adjuvant therapy should be administered when necessary. The involvement of multiple subspecialties in the management of these patients is highly recommended. 52 references.

    Annas, G J

    1987-01-01

    It has been suggested that the advance of science and technology in the West has changed both the relationship of man to nature and of man to man. With regard to human reproduction, science and technology in medicine may certainly change the relationship of man to nature and of man to man, but also the concept of what it means to be human. Efforts must be taken to guarantee the rights of all humans. The author explores developing reproductive medical technology to consider how it may change our concept of humanness and how that change may be accommodated, encouraged, or impeded by the relationship between the government and its pregnant citizens as defined by the US Constitution and the right to privacy. Sections discuss the Constitution at the beginning of life; sterilization and the right to procreate; contraception, abortion, and the right not to procreate; and surrogacy. The author also discusses constitutional issues when the interests of a pregnant woman conflict with those of the fetus in terms of fetal surgery, forced cesarean-section cases, and the fetal abuse case of Pamela Monson Stewart.

    As part of drug development, drug companies conduct experiments to gather data about the potential toxicity of medications in pregnant and lactating animals. Increasingly, physiologically based pharmacokinetic models are developed to simulate drug concentrations in pregnant and lactating women. As these women are not usually included in clinical trials, targeted postapproval safety monitoring, registries, or clinical studies may be performed to gather safety and efficacy information about drug use in these special populations.

    Infection with Clostridium difficile has been shown to have particularly poor outcomes for pregnant women, including an increased risk of death. The purpose of this study was to investigate the prevalence, genotypic distribution, and characterization of C. difficile strains isolated from pregnant women without diarrhea in China. As part of this study, 3.7% (37 out of 1009) of samples acquired from pregnant females tested positive for C. difficile. Of these positive samples, 27.0% (10) were toxigenic isolates containing both toxin A and toxin B genes (A+B+), 13.5% (5) of the variant strains contained the toxin B gene (A-B+) only, while the rest were non-toxigenic isolates (59.5%, 22 isolates). Among the non-pregnant women without diarrhea tested, 1.4% (9 of 651) contained toxigenic isolates (all of which were A+B+). Sixteen different sequence types (STs) were isolated during the course of this study. ST-37 (ribotype 017) and ST-54 (ribotype 012) were the most frequent toxigenic types observed in pregnant women. All strains showed susceptibility to the antibiotics metronidazole and vancomycin. The resistance rates of toxigenic C. difficile strains isolated from pregnant females to clindamycin, erythromycin, moxifloxacin, levofloxacin, and rifampicin were 20%, 46.7%, 13.6%, 46.7% and 13.3%, respectively. There was no significant difference between resistance rates of toxigenic and non-toxigenic strains with respect to their susceptibility to these antibiotics. However, when compared with the same data from non-pregnant women, toxigenic strains from pregnant women showed lower resistance rates to clindamycin (P < 0.05).

    Low back pain during pregnancy is a common problem with a high prevalence among pregnant athletes. The etiology of pregnancy-related low back pain remains unclear, although more evidence is supporting a biomechanical/musculoskeletal origin. This article will review the causes of low back pain in athletes and pregnant women, differentiate low back from pelvic girdle pain, and discuss the treatment and prevention of pregnancy-related low back and pelvic girdle pain.

    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. To describe the antiviral treatment patterns for chronic hepatitis B (CHB) among pregnant and nonpregnant women. Methods. Using 2011 MarketScan claims, we calculated the rates of antiviral treatment among women (aged 10–50 years) with CHB. We described the pattern of antiviral treatment during pregnancy and ≥1 month after delivery. Results. We identified 6274 women with CHB during 2011. Among these, 64 of 507 (12.6%) pregnant women and 1151 of 5767 (20.0%) nonpregnant women received antiviral treatment (P < 0.01). Pregnant women were most commonly prescribed tenofovir (73.4%) and lamivudine (21.9%); nonpregnant women were most commonly prescribed tenofovir (50.2%) and entecavir (41.3%) (P < 0.01). Among 48 treated pregnant women with an identifiable delivery date, 16 (33.3%) were prescribed an antiviral before pregnancy and continued treatment for at least one month after delivery; 14 (29.2%) started treatment during the third trimester and continued at least one month after delivery. Conclusion. Among this insured population, pregnant women with CHB received an antiviral significantly less often than nonpregnant women. The most common antiviral prescribed for pregnant women was tenofovir. These data provide a baseline for assessing changes in treatment patterns with anticipated increased use of antivirals to prevent breakthrough perinatal hepatitis B virus infection. PMID:25548510

    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.

    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.

    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

    Persistent organic pollutants such as polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and organochlorine pesticides (OCPs) are of global concern because of their widespread contamination and adverse health effects. Potential endocrine disruption, especially of thyroid status by PCBs has been repeatedly suggested in both experimental and epidemiological studies. However the associations with PBDEs or OCPs have been arguable especially in human populations. We investigated the associations between major groups of POPs and thyroid hormone balances among pregnant women. One hundred five pregnant women at delivery were recruited from four cities of Korea in 2011 and were investigated. Blood samples were collected within a day before delivery. Serum was then analyzed for 19 PCBs, 19 PBDEs, and 19 OCPs, along with five thyroid hormones (free and total T3 and T4, and TSH). Several PCBs such as PCB28, 52, and 118 showed negative associations with T3 or T4. BDE47 and total PBDEs showed significant associations with T3 or T4. For OCPs, dichlorodiphenyltrichloroethanes (DDTs) and hexachlorobenzene (HCB) were generally associated with reduction of T3 or T4. The thyroid hormone levels of all subjects were within the reference range, however exposure to several target POPs were clearly related with potential for disrupting thyroid hormone balance among pregnant women, at the current level of exposure. Although subtle, the changes in thyroid hormones should be seen with caution because even minor changes within pregnant women may have significant consequences especially on sensitive population like fetus.

    A 90-day finishing trial involving 144 feedlot heifers was conducted to compare the performance parameters and carcass characteristics of open heifers, therapeutically aborted heifers, and pregnant heifers. In the first 28 days of the trial, the aborted heifers had reduced (p < 0.05) feed intake (FI), average daily gain (ADG), and feed efficiency (FE) compared to pregnant and open heifers. Over the entire trial, on a live weight basis, the aborted group had reduced (p < 0.05) final weight, ADG, and FE compared to pregnant and open heifers. However, when the data were adjusted for total uterine weight, the aborted and open heifers had improved (p < 0.05) final weight, ADG, and FE compared to pregnant heifers. The aborted and open group had a higher (p < 0.05) carcass weight, rib eye area, dressing percentage, and cutability estimate compared to the pregnant heifers. The aborted group had lower (p < 0.05) carcass weight than the open heifers. Over the entire 90-day feeding period, there were no statistically significant differences among the groups with respect to feed intake (FI), average fat, grade fat, and carcass grades. Also, there were no significant health problems or mortality in any of the groups. In the economic analysis, aborted heifers returned $26.41 per head more than pregnant heifers. Open heifers returned $39.94 per head more than aborted heifers, and $66.35 more than pregnant heifers. Thus, aborting feedlot heifers during the second trimester was determined to be a safe and cost effective management decision. PMID:17423875

  11. A population pharmacokinetic model of piperaquine in pregnant and non-pregnant women with uncomplicated Plasmodium falciparum malaria in Sudan

    PubMed Central

    2012-01-01

    Background Pregnancy is associated with an increased risk of developing a malaria infection and a higher risk of developing severe malaria. The pharmacokinetic properties of many anti-malarials are also altered during pregnancy, often resulting in a decreased drug exposure. Piperaquine is a promising anti-malarial partner drug used in a fixed-dose combination with dihydroartemisinin. The aim of this study was to investigate the population pharmacokinetics of piperaquine in pregnant and non-pregnant Sudanese women with uncomplicated Plasmodium falciparum malaria. Method Symptomatic patients received a standard dose regimen of the fixed dose oral piperaquine-dihydroartemisinin combination treatment. Densely sampled plasma aliquots were collected and analysed using a previously described LC-MS/MS method. Data from 12 pregnant and 12 non-pregnant women were analysed using nonlinear mixed-effects modelling. A Monte Carlo Mapped Power (MCMP) analysis was conducted based on a previously published study to evaluate the power of detecting covariates in this relatively small study. Results A three-compartment disposition model with a transit-absorption model described the observed data well. Body weight was added as an allometric function on all clearance and volume parameters. A statistically significant decrease in estimated terminal piperaquine half-life in pregnant compared with non-pregnant women was found, but there were no differences in post-hoc estimates of total piperaquine exposure. The MCMP analysis indicated a minimum of 13 pregnant and 13 non-pregnant women were required to identify pregnancy as a covariate on relevant pharmacokinetic parameters (80% power and p=0.05). Pregnancy was, therefore, evaluated as a categorical and continuous covariate (i.e. estimate gestational age) in a full covariate approach. Using this approach pregnancy was not associated with any major change in piperaquine elimination clearance. However, a trend of increasing elimination

    Agrobacterium tumefaciens (radiobacter) is usually a plant pathogen, but is isolated occasionally from human clinical specimens, frequently along with other bacteria. Agrobacterium tumefaciens (radiobacter) has been isolated from blood, central intravenous catheters, peritoneal fluid, urine, and cellulitis aspirates, often in immunocompromised individuals. This report details the isolation of A. tumefaciens (radiobacter) from the blood of a pregnant woman, as well as from the blood of her stillborn, premature fetus. It is, to our knowledge, the first report of such an occurrence.

    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.

  14. Bone strontium in pregnant and lactating females from archaeological samples.

    Because plants and animals consume or absorb different amounts of strontium and calcium, anthropologists are able to use strontium/calcium (Sr/Ca) ratios from archaeologically recovered human bone to estimate the relative contributions of meat and plants to paleodiets. Often females exhibit higher Sr/Ca ratios than males, a fact usually attributed to lower meat intake among women. However, in vivo and in vitro experiments with laboratory animals show that pregnancy and lactation elevate maternal bone strontium and depress maternal bone calcium because 1) strontium is discriminated against in favor of calcium in the transport of ions to the placenta and mammary glands and 2) pregnancy and lactation facilitate absorption of alkaline earth metals from the gut. In this study, bone Sr/Ca ratios and strontium concentrations were compared between reproductive-age females, postmenopausal females, and adult males from two late prehistoric Native American sites in Georgia: the King site (N = 43) and the Etowah site (N = 51). At the King site, the mean Sr/Ca ratio of females was over 14% greater than that of males. At Etowah, the mean strontium level of reproductive-age females exceeded that of postmenopausal females by almost 25%. Most of the difference, it is argued, is due to pregnancy and lactation. A dietary preference among pregnant and lactating women for foods high in alkaline earths, particularly nuts and corn, may also be partially responsible. Until we assess the influence variables other than nutrition exert on trace element concentrations, our reconstructions of paleodiets will be suspect. PMID:2801910

    Fifty pregnant goats, inoculated intramuscularly at different gestational stages with a non-cytopathic ovine pestivirus or a cytopathic bovine pestivirus, all developed pestivirus-neutralizing antibodies within 5 weeks of inoculation. The incidence of reproductive failure was similar for the two agents. Parturition at term with only healthy kids occurred in 13 (26 per cent) of the goats. Viable kids were not born to any of the 17 goats inoculated at about day 40 of gestation. Three of the 17 delivered dead or weak kids, seven aborted and three of seven which were necropsied during pregnancy had markedly underdeveloped and autolysed or mummified fetuses in utero, while four were barren. When inoculated at around the 60th day of gestation, two of 18 animals gave birth to only healthy kids, 12 to dead and/or weak kids, two aborted and, at necropsy, a small, decomposed fetus was found in one goat while one other was barren. In this group, one kid was ataxic and seven others had body tremors characteristic of border disease. One of the latter kids was viable. Of 15 goats inoculated at around day 100 of gestation, 11 gave birth to healthy kids only, three to dead and/or weak kids and one aborted. In 23 progeny, histological changes in the central nervous system (CNS) consisted mainly of cerebral white matter necrosis, cerebellar dysplasia, hypercellular areas in white matter and lymphocytic perivascular cuffings. All seven weak-born kids with signs of border disease had CNS lesions, particularly cerebellar dysplasia and/or hypercellular areas. Non-cytopathic pestivirus was isolated from tissues from all eight progeny examined in the 40-day inoculation group, from tissues and/or serum from 10 of 23 progeny in the 60-day group, and from four of 24 in the 100-day group. Persistent infection was demonstrated in a healthy kid, in a viable shaker and in two other kids which appeared normal at birth. Examination of offspring before ingestion of colostrum revealed pestivirus

    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.

    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.

    Heat flux (conductive and convective heat) and oxygen consumption of the pregnant uterus and its content were measured simultaneously in the same group of pregnant ewes during the acute postoperative period, during a chronic resting period, and during alpha- and beta-adrenergic-receptor stimulation with norepinephrine and ritodrine. Results indicated four conclusions. First, an excellent correlation existed between heat flux and oxygen consumption in the acute and chronic resting condition as well as during increasing uteroplacental vascular resistance and decreasing blood flow produced by norepinephrine infusion; the correlation was not as good during ritodrine infusion. Second, during rest, about 85% of heat generated by the pregnant uterus is eliminated through the uteroplacental circulation while the remaining heat diffuses through the myometrium. Third, during decreasing uteroplacental blood flow and elevated resistance, the pregnant uterus is able to maintain a normal thermostasis by widening the temperature difference in the blood entering and leaving the uterus and by increasing the myometrial heat exchange; oxygen consumption also is maintained at normal level through increase in oxygen extraction. Fourth, with the exception of uteroplacental circulation, the circulatory, metabolic, and thermal conditions of the pregnant ewe are not different after 5 hours from 5 to 7 days after the surgical procedure.

    Study Objective: Pregnant women suffer from sleep disturbance, which may be aggravated by passive smoking. In this study we investigated the effects of passive smoking on sleep disturbance during pregnancy. Design: Two cross-sectional questionnaire surveys conducted in 2002 and 2006. Setting: Clinical institutions specializing in obstetrics and gynecology that participated in the nationwide surveys: 260 in the 2002 survey and 344 in the 2006 survey. Participants: 16,396 and 19,386 pregnant women in Japan surveyed in 2002 and 2006, respectively. Intervention: N/A. Measurements and Results: Pregnant women exposed to passive smoking were likely to have sleep disturbances, such as subjective insufficient sleep, difficulty in initiating sleep, short sleep duration, and snoring loudly/breathing uncomfortably. Smoking pregnant women had the same sleep disturbances and also experienced excessive daytime sleepiness and early morning awakening. The prevalence of 5 types of sleep disturbance (insufficient sleep, difficulty in initiating sleep, short sleep duration, excessive daytime sleepiness, and snoring loudly/breathing uncomfortably) among nonsmokers with environmental tobacco smoke showed a mean value intermediate between that of active smokers and that of nonsmokers without environmental tobacco smoke. Conclusion: Passive smoking is independently associated with increased sleep disturbance during pregnancy.

    We studied the chronic effect of exercise during water immersion, associated with thermal stress (water temperature at 22, 35 and 40 degrees C) at an intensity of 80% of maximal work load supported in pregnant rats (P) and non-pregnant female rats (NP). P and NP were subdivided into three subgroups according to water temperature during exercise (P22 and NP22; P35 and NP35; P40 and NP40). The animals were submitted to daily swimming sessions of 10-15 min, for 19 days of pregnancy (P) or experimental conditions (NP). Plasma concentration of triglycerides, cholesterol, glucose, total protein, albumin and corticosterone were determined 24 h after the last exercise session. Weight gain and rectal temperature pre- and post-swimming session were also determined. The offspring were examined just after caesarian section on the 20th day of pregnancy to check weight, length and litter size. Pregnant rats showed an increase of triglycerides, reduction of glycemia, total protein and albumin and cholesterol (at 35 degrees C) when compared to non-pregnant animals. Such effects probably lead to an adequate delivery of substrate to the fetus and prepare the mother for lactation. Daily thermal stress did not modify metabolic responses to exercise in pregnant rats. Results also show a deleterious effect on offspring when the mother is exposed daily to extreme temperatures during swimming. These results suggest that water temperature (cold and hot) in swimming have to be considered to avoid damage in fetal development.

    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

    Malaria is still a major threat to health in tropical regions. Particular attention should be directed to malaria prevention in infants and pregnant women as they are at high risk for plasmodial infection and complicated malaria. In this review, we summarize and discuss current evidence on malaria prevention in pregnant travellers. As neither anti-mosquito measures nor anti-malarial drugs have been proven to be unequivocally safe or toxic in pregnant women, the individual risk assessment should take into account the risk of transmission at the destination, the benefit of travelling despite being pregnant as well as the individual risk perception. All three factors may differ in various groups of travellers like tourist travellers, expatriate travellers as well as those visiting friends and relatives. For pregnant women, mefloquine appears to be the drug of choice for prophylaxis and stand by-therapy if no contraindications exist - despite recent renewed warnings related to prolonged side effects. In areas with high resistance against mefloquine or in women with contraindications to mefloquine, atovaquone-proguanil or artemether-lumefantrine should be considered as an option for stand-by emergency therapy. Nevertheless, evidence on the safety of anti-malarials especially during the first trimester is still insufficient.

    Aim To understand the prevalence of functional constipation in pregnant women and to analyze the impact of its risk factors. Methods We searched hospital databases for women who were 37–41 weeks pregnant (1698 cases) from July 2012 to January 2014 in four hospitals in Shanghai. We reviewed factors including general data, living and eating habits, psychological history, past history of defecation in the 6 months before pregnancy and defecation after pregnancy. Data were analyzed using SPSS software. Results Pregnant women who were more than 35 years old, with a pre-pregnancy body mass index >24, who were highly educated and employed in a sedentary occupation, showed a higher prevalence of functional constipation. Multivariate logistic regression analysis indicated that the prevalence of functional constipation among pregnant women was related to age, pre-pregnancy body mass index, diet, exercise, occupation, psychological factors, threatened abortion in early pregnancy and constipation history. Conclusion The prevalence rate of functional constipation in pregnant women was significantly higher than in the general population. PMID:26208169

    Luteal development is regulated by many locally produced mediators, e.g., prostaglandins and angiogenic factors. However, the role and function of vasoactive factors in the canine corpus luteum (CL) remain largely unknown. Consequently, expression of the endothelin (ET) receptors-A and -B (ETA and ETB, revealing vasoconstriction and vasodilator properties respectively), the ET-converting enzyme (ECE1) and ET1, -2 and -3 were investigated in CL from non-pregnant dogs (days 5, 15, 25, 35, 45 and 65 post-ovulation), and at selected stages of pregnancy (pre-implantation, post-implantation, mid-gestation), and during normal and antigestagen-induced prepartum luteolysis/abortion. The interrelationship between PGE2 and the ET system was investigated in PGE2-treated canine primary lutein cells from early CL. ET1 did not change significantly over time; ET2, ECE1 and ETB were elevated in early CL and were downregulated towards the mid/late-luteal phase. The prepartum increase of ET2 was significant. ET3 increased gradually, and was highest in late CL and/or at prepartum luteolysis. ETA remained constant until the late CL phase and increased only during prepartum luteolysis. ET1 was localized to the luteal cells, and ET2, ET3 and ETA to vascular endothelium. ECE1 and ETB were detected at both locations. Except for upregulated ET1 and lack of effect on ET2, antigestagen applied to mid-pregnant dogs evoked similar changes to those observed during normal luteolysis. PGE2 upregulated ETB in treated cells; ETA and ET1 remained unaffected, and ET2 decreased. A modulatory role of the ETs in canine CL, possibly in association with other factors (e.g., PGE2 and progesterone receptor), is strongly indicated.

    The research was aimed at describing the meaning of the rubella vaccine to women who were discovered pregnant after having received the measles-rubella vaccine during the 2001 campaign against rubella, and who lived in 10 cities within the region of DIR XX from São João da Boa Vista. The theory of Social Representation was used as a reference framework for the research, and data were collected through the Collective Subject Discourse technique, involving 18 women who either were pregnant or became pregnant within 30 days after having received the vaccine. Through their discourse, it was possible to unveil the diversity of meanings the rubella vaccine has when dispensed during pregnancy, characterized as a threat to their and their children's physical integrity and to their conjugal relationship. The meanings constitute an important source of information that allows health professionals and administrators to reflect, so they can reconsider their role as health promoters.

    The present literature review was conducted to determine what information has been published on the topic of undocumented pregnant migrants. Scientific databases and gray literature sources were searched for articles published between January 1967 and September 2010. Eighty-seven articles met the inclusion criteria and were reviewed. A final sample of 23 articles was included in the review. Existing evidence suggests that pregnant undocumented migrants living in Western societies tend to be younger, unmarried, and more likely to be employed in the domestic sector than documented migrants and permanent residents. They have less access to prenatal care and consult later in pregnancy than controls. Findings concerning delivery and birth outcomes are conflicting and subject to several biases. Little has been published on programs to address the needs of undocumented pregnant women living in Western countries. More research on the particular health and social issues faced by these women is needed.

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

    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

    The objective of this study was to identify major components of, and influential factors in, problematic tasks performed by pregnant women employed in education, health care and service areas. Seventy-two pregnant women were surveyed using specially designed questionnaires consisting of an Initial Survey, a Job Analysis Questionnaire and a Task Description Questionnaire. Forty-four subjects (60%) had difficulty performing at least one work task and reported 105 tasks that were problematic at work. Reaching above the head, bending forward, bending and twisting, pushing, repeating actions and working at a fast pace were identified as the task components requiring the greatest level of effort. Excessive effort, excessive time, getting tired, repetitive actions, stress and fear of injury were identified as factors that had strong associations with the six major task components. Findings of this study suggest that these task components and factors should be considered when designing, assigning or analysing tasks for working pregnant women. PMID:16540440

    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.

    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.

    Nurses working with pregnant Hispanic women can create barriers in the health care system by not understanding or accepting the variety of ways in which the Hispanic culture perceives and treats pregnancy. This article describes nursing care of low-income, battered Hispanic pregnant women within the context of the Hispanic culture and discusses clinical and nursing implications for interventions. To deliver effective culturally competent care to battered Hispanic pregnant women, nurses need to have a thorough understanding of the variables that influence the health care of Hispanics in the United States, such as the scope of wife abuse in the Hispanic population, sociodemographic characteristics of the Hispanic population in the United States, Hispanic women's access to health care, pregnancy in the Hispanic population, and health care practices of Hispanics in the United States. This will facilitate screening, education, and guidance without upsetting the often precarious security of this period.

    We construct a verbal and graphical theory (the “fecundity-limitation hypothesis”) about how constraints on the brooding space for embryos probably truncate individual fecundity in male-pregnant and female-pregnant species in ways that should differentially influence selection pressures for multiple mating by males or by females. We then review the empirical literature on genetically deduced rates of multiple mating by the embryo-brooding parent in various fish species with three alternative categories of pregnancy: internal gestation by males, internal gestation by females, and external gestation (in nests) by males. Multiple mating by the brooding gender was common in all three forms of pregnancy. However, rates of multiple mating as well as mate numbers for the pregnant parent averaged higher in species with external as compared with internal male pregnancy, and also for dams in female-pregnant species versus sires in male-pregnant species. These outcomes are all consistent with the theory that different types of pregnancy have predictable consequences for a parent's brood space, its effective fecundity, its opportunities and rewards for producing half-sib clutches, and thereby its exposure to selection pressures for seeking multiple mates. Overall, we try to fit these fecundity-limitation phenomena into a broader conceptual framework for mating-system evolution that also includes anisogamy, sexual-selection gradients, parental investment, and other selective factors that can influence the relative proclivities of males versus females to seek multiple sexual partners.

    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

    Earlier studies in animals have suggested an essential role for Si in connective tissues, but such works have not been replicated per se. Nonetheless, a study conducted in 2000 has reported that Si may be essential during pregnancy for the growing fetus, since serum Si concentrations in infants were approximately 300 % higher than those in older children and adults and serum Si concentrations in pregnant women were approximately 300 % lower than those in age-matched non-pregnant controls. To reproduce these potentially important findings, in the present study, serum Si concentrations were measured in fourteen pregnant women (15-24 weeks of gestation) and compared with those of seventeen non-pregnant, non-lactating female controls. Serum Si concentrations were also measured in fourteen full-term mothers at the time of delivery and in the umbilical cord (UC) vein and artery where possible. Fasting serum Si concentrations in pregnant women were not significantly different from those of the female controls and showed little change with advancing gestation (r 0·2). Mean serum Si concentrations in the UC vein samples were 52 % higher, while those in the UC artery samples were 235 % higher than those in the maternal forearm vein samples, although data were widely spread and differences were not significant. Mean maternal forearm vein Si concentrations at delivery were 50 % lower than those of pregnant women and female controls, but, again, these were not significant. Overall, we note that there are significant analytical challenges in comparing baseline Si levels between different groups; notwithstanding, our findings cannot confirm a reduction in fasting serum Si levels during pregnancy, but, equally, we cannot rule out higher serum Si levels in newborns than in their mothers, and further work is required.

    Background: Evidence for an association between exposure of pregnant women to chlorination disinfection by-products and adverse birth outcomes is inconsistent and inconclusive. Aims: To evaluate the use of a questionnaire in a population of pregnant women to assess their exposure to water, examine the validity of the questionnaire by a seven day diary, and to obtain a better understanding of the exposure of pregnant women to water in Central London. Methods: A total of 147 pregnant women were asked to complete a questionnaire. Information was requested on their exposure to water from cooking and washing up, showering and bathing, food and drink, and swimming. Demographic and socioeconomic information were also recorded. For validation purposes, women were asked to complete a seven day diary at home. Results: The average exposure duration was 338.5 min/week for cooking and washing up, 172.2 min/week for bathing and showering, and 67.9 min/month for swimming. The total fluid intake was 18.9 l/week of which, on average, 18% was cold tap water; 30% of this tap water was consumed outside the home. The correlation between questionnaire and diary data was generally good to very good, although women tended to overestimate their exposure in the questionnaire compared to the diary. Conclusions: Information was obtained on the daily exposure of pregnant women in Central London to chlorinated water at home, work, and elsewhere. The questionnaire was found to be a valid method to assess the exposure of pregnant women to water and the response rate was higher than for diaries. PMID:15090668

    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. PMID:24740724

    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

    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

    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. PMID:26157673

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. PMID:25455431

    The purpose of this study was to further knowledge of health care seeking behavior among pregnant women in rural Haiti. Eighty-two pregnant women were interviewed to assess care seeking behaviors during pregnancy, satisfaction with services, reliance on social networks, and management of pregnancy-related illness. Twenty-five percent reported not seeking care in the formal health sector for a pregnancy-related illness; 32% delayed seeking care. Women relied primarily on their husbands and mothers for health care advice during pregnancy and times of illness, and coped with illness by lying down. Strategies for improving awareness and health care access are discussed. PMID:17060181

    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.

    A case of disseminated rectal cancer in a 32-year-old pregnant woman is described. Pain was her main complaint, but this had been ascribed to haemorrhoids and treated with topical agents. She was diagnosed with rectal cancer late in the third trimester when her midwife referred her for surgical assessment. Following caesarian section, diagnostic workup showed multiple liver metastases. Rectal cancer in pregnancy is rare, while haemorrhoids are common. We recommend keeping the differential diagnoses in mind and performing a digital rectal examination if pregnant women have anal symptoms.

    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.

    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.

    Phthalates are known reproductive and developmental toxicants in experimental animals. However, in humans, there are few data on the exposure of pregnant women that can be used to assess the potential developmental exposure experienced by the fetus. We measured several phthalate metabolites in maternal urine, maternal serum, and cord serum samples collected at the time of delivery from 150 pregnant women from central New Jersey. The urinary concentrations of most metabolites were comparable to or less than among the U.S. general population, except for mono(2-ethylhexyl) phthalate (MEHP), mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP), and mono(2-ethyl-5-oxohexyl) phthalate (MEOHP), three metabolites of di(2-ethylhexyl) phthalate (DEHP). The median urinary concentrations of MEHHP (109 mug/l) and MEOHP (95.1 mug/l) were more than 5 times their population-based concentrations, whereas the median urinary concentration of MEHP was more than 20 times higher. High concentration of MEHP may indicate a recent exposure to the parent chemical DEHP in the hospital shortly before the collection of the samples. Calculation of daily intakes using the urinary biomarker data reveals that none of the pregnant women tested had integrated exposures to DEHP greater than the Agency for Toxic Substances and Disease Registry's minimal risk levels (MRLs chronic 60, intermediate 100 mug/kg/day). No abnormal birth outcomes (e .g., birth weight, Apgar Score, and gestational age) were noted in those newborns whose mothers had relatively greater exposure to DEHP during the perinatal period than others in this study. Significantly greater concentrations and detection frequencies in maternal urine than in maternal serum and cord serum suggest that the urinary concentrations of the phthalate metabolites may be more reliable biomarkers of exposure than their concentrations in other biological specimens.

    Background Pregnancy and tuberculosis treatment or prophylaxis can affect efavirenz pharmacokinetics, maternal human immunodeficiency virus type 1 (HIV-1) treatment outcomes, and mother-to-child transmission (MTCT) risk. Methods We evaluated a prospective cohort of pregnant, HIV-infected women with and without tuberculosis in Soweto, South Africa. Pharmacokinetic sampling was performed at gestation week 37 and during the postpartum period. Efavirenz trough concentrations (Cmin) were predicted using population pharmacokinetic models. HIV-viral load was measured at delivery for mothers and at 6 weeks of age for infants. Results Ninety-seven women participated; 44 had tuberculosis. Median efavirenz Cmin during pregnancy was 1.35 µg/mL (interquartile range [IQR], 0.90–2.07 µg/mL; 27% had an efavirenz Cmin of < 1 µg/mL), compared with a median postpartum value of 2.00 µg/mL (IQR, 1.40–3.59 µg/mL; 13% had an efavirenz Cmin of < 1 µg/mL). A total of 72% of pregnant women with extensive CYP2B6 genotypes had an efavirenz Cmin of <1 µg/mL. Rifampin did not reduce the efavirenz Cmin. Isoniazid (for prophylaxis or treatment), though, reduced the rate of efavirenz clearance. At delivery, median durations of ART were 13 weeks (IQR, 9–18 weeks) and 21 weeks (IQR, 13–64 weeks) for women with and those without tuberculosis, respectively; 55% and 83%, respectively, had a viral load of <20 copies/mL (P = .021). There was 1 case of MTCT. Conclusions Pregnancy increased the risk of low efavirenz concentrations, but MTCT was rare. A detectable HIV-viral load at delivery was more common among pregnant women with tuberculosis, in whom ART was generally initiated later. PMID:25081933

    The attractiveness of pregnant women for mosquitoes was investigated in a peri-urban site in New Halfa, eastern Sudan, in September-October 2003. For 20 nights, the mosquitoes feeding on nine pregnant and nine non-pregnant women sleeping under untreated bednets were collected. The women slept outdoors, in the yards of nine houses, each yard holding one pregnant and one non-pregnant woman. In general, each pregnant woman attracted significantly more Anopheles arabiensis (the main vector of Plasmodium falciparum in the area) than each non-pregnant women, with mean biting rates of 0.94 and 0.49 bites/woman-night, respectively (P = 0.005). In contrast, the two groups of women attracted similar numbers of the other mosquito species collected, which were all culicine. Impregnated bednets need to be used in the study area, at least by the pregnant women (who appear to be at particularly high risk of acquiring malaria).

    One hundred and ninety three consecutive pregnant women attending peripheral antenatal clinics attached to Ngwelezana Hospital, Empangeni, Kwa-Zulu, were examined for evidence of sexually transmitted pathogens. The following incidences were found: Trichomonas vaginalis 49.2% (95), Candida spp 38.3% (74), Chlamydia trachomatis 11.4% (22), Gardnerella vaginalis 6.2% (12), Neisseria gonorrhoeae 5.7% (11), positive syphilis serology results 11.9% (23), hepatitis B surface antigen 4.1% (eight). No woman had antibody to human immunodeficiency virus (HIV). Dyskaryotic smears were found in 20 (10.4%). Human papillomavirus (HPV) was detected cytologically in 11 (5.7%). The range of sexually transmitted pathogens found in this rural community was similar to that found in urban groups studied in South Africa. PMID:2807289

    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.

    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

    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

    Out-of-hospital cardiac arrest is a leading cause of death in the United States. Pregnant women are not immune to cardiac arrest, and the treatment of such patients can be difficult. Pregnancy is a relative contraindication to the use of therapeutic hypothermia after cardiac arrest. A 20-year-old woman who was 18 weeks pregnant had an out-of-hospital cardiac arrest. Upon her arrival at the emergency department, she was resuscitated and her circulation returned spontaneously, but her score on the Glasgow Coma Scale was 3. After adequate family discussion of the risks and benefits of therapeutic hypothermia, a decision was made to initiate therapeutic hypothermia per established protocol for 24 hours. The patient was successfully cooled and rewarmed. By the time she was discharged, she had experienced complete neurologic recovery, apart from some short-term memory loss. Subsequently, at 40 weeks, she delivered vaginally a 7-lb 3-oz girl whose Apgar scores were 8 and 9, at 1 and 5 minutes respectively. To our knowledge, this is only the 3rd reported case of a successful outcome following the initiation of therapeutic hypothermia for out-of-hospital cardiac arrest in a pregnant woman. On the basis of this and previous reports of successful outcomes, we recommend that therapeutic hypothermia be considered an option in the management of out-of-hospital cardiac arrest in the pregnant population. To facilitate a successful outcome, a multidisciplinary approach involving cardiology, emergency medicine, obstetrics, and neurology should be used. PMID:26413021

    2013-01-01

    Introduction Malaria prevention methods are diverse. Their availability sometimes does not guarantee effective usage and the use of each method in isolation may not provide the necessary results for the fight against malaria. Pregnant women are relatively more vulnerable and so it is recommended that they should be protected against malaria. Proper protection will require malaria prevention methods in combination. This study seeks to find out what methods pregnant women use and how many of them use these methods. Methods Information on the use of malaria prevention methods was collected from pregnant women attending prenatal clinics in health institutions within the Biyem Assi health district of Yaounde VI subdivision using a pretested questionnaire. Analysis was done using SPSS version 16 (Chicago IL USA). Results The study revealed that 82.5% of women used at least one method of malaria prevention; 12% used four methods (insecticides, bednets, indoor residual spraying and Sulphadoxine Pyrimethamine) in combination. The most used method was mosquito bednet, 82.5%. Some of the women 17.5% did not use any of the prevention methods. Conclusion Use of malaria prevention methods in combination is not considered a priority by pregnant women. Sensitization campaigns by governments and NGOs should give that a priority position.

    Several medical - biological and social - hygienic factors have been found to account for the definite increase in the incidence of thyroid gland disorders in reproductive age and pregnant women. Aim of our study was to identify the risk factors for development of thyroid gland pathology in outpatient pregnant women. Observational study - "case - control" study has been conducted at the base of David Gagua Hospital Ltd. Main (study) group involved 292 pregnant patients with established thyroid pathology. Control group included 58 conditionally healthy pregnant participants without any demonstrated thyroid pathology. Study of risk factors was performed by initial interviewing and specialized questionnaire recording process (so-called two-stage model of interviewing). Characteristics of diet, sleep, physical activity, including harmful habits, socio-economic and hereditary factors were studied; quantitative indices of risk for each component were calculated: odds ratio (OR) and attributable risk (AR), taking into account 95% confidence interval (CI). The Pearson's criterion χ2 with respective P value and the calculator developed by International Society of Evidence-based Medicine were used to obtain the final results. Statistically significant risk factors for development of thyroid pathology were identified, which included: Thyroid gland diseases and hereditary history of diabetes mellitus; low economic income, unfavorable living conditions, unhealthy dietary habits. Despite of the difficulty of assessment of causative relationship between above mentioned components, their strong correlation should be taken into account when defining the strategy of preventive measures, moreover the most part of identified risk factors are manageable.

    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

    To examine individual, interpersonal, family, and community correlates associated with moderate-to-severe depressive symptoms among pregnant adolescents. A total of 249 primarily African American and Hispanic pregnant adolescents ages 15-18 years were recruited into either an intervention group utilizing Centering Pregnancy prenatal care and case management, or to a comparison group receiving case management only. Moderate-to-severe depressive symptoms were defined as a score ≥16 on the Center for Epidemiologic Studies Depression Scale (CES-D). Intervention and comparison groups did not significantly differ on demographic characteristics or depression scores at baseline. A total of 115 (46.1 %) participants met criteria for moderate-to-severe depressive symptoms at entry into the program. Pregnant adolescents who were moderately-to-severely depressed were more likely to be African American, to have reported limited contact with the father of the baby, and to have experienced prior verbal, physical or sexual abuse. Depressed adolescents also experienced high levels of family criticism, low levels of general support, and exposure to community violence. A significant number of pregnant adolescents were affected by depression and other challenges that could affect their health. Comprehensive interventions addressing these challenges and incorporating partners and families are needed.

    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 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

    Teenage pregnancy and childbearing remain pressing public health issues that have garnered attention from public health officials and social services agencies. This paper reports on the initial implementation and formative evaluation of a journaling program used as a means of communicating health information to pregnant and parenting adolescents (young women age 15-19) while also providing participants with a means of self-expression. The journaling prototype was implemented in a community-based agency in the Midwest by Family Support Specialists (FSSs) who made home visits on a monthly basis to assist pregnant and parenting adolescents (n=52) with successful family planning and public health education. A mixed method approach of qualitative (analysis of journals, field notes, and responses of semi-structured interviews with FSSs) and quantitative (questionnaires from pregnant and parenting adolescent respondents) data with purposive sampling was employed to evaluate the implementation of the journaling intervention. Twenty of the 52 study participants were pregnant when the journaling intervention was implemented, while 32 were not pregnant, but recently had a child and were currently parenting. Two core themes emerged from analysis of the data after the implementation of the journals: (1) usefulness of the journal and responsiveness to participants' information needs and (2) functionality challenges. The results offer practical starting points to tailor the implementation of journaling in other contexts. Further, areas for improvement emerged regarding the distribution timeline for the journal and the content of the journal itself. As such, we discuss the lessons learned through this collaborative project and suggest opportunities for future phases of the journal intervention. PMID:24973758

    I is essential for thyroid hormone synthesis and neurological development. Various changes occur in thyroid hormone metabolism during pregnancy and I requirements increase significantly. The purpose of this study was to investigate I status among pregnant women in Trabzon, formerly a severely I-deficient area but shown to have become I sufficient following mandatory iodisation of table salt based on monitoring studies among school-age children (SAC) in the area. A total of 864 healthy pregnant women with a median age of 28 (25th-75th percentile 17-47) years participated in the study. None of them were using I-containing supplement. All of them were screened for use of iodised salt, obstetric history, thyroid function tests and urinary I concentrations (UIC), and thyroid ultrasonography was performed. Median UIC was 102 (25th-75th percentile=62-143) μg/l. Median UIC of the patients according to trimesters were 122 µg/l at the 1st, 97 µg/l at the 2nd and 87 µg/l at the 3rd trimester. UIC in the 1st trimester was higher compared with the 2nd and 3rd trimesters (P<0·017). Nodules were present in 17·7% of women (n 153). The rate of iodised salt usage among pregnant women was 90·7%. Our study demonstrates that, although the I status among SAC has been rectified, I deficiency (ID) is still prevalent among pregnant women. Current knowledge is in favour of I supplementation in this group. Until the effects of maternal I supplementation in mild ID have been clarified by large-scale prospective controlled trials, pregnant women living in borderline defficient and I-sufficient areas, such as Trabzon city, should receive 100-200 µg/d of I-containing supplements in addition to iodised salt.

    Objectives: To determine the leukocyte esterase (LE) activity in vaginal lavage fluid of women with acute and recurrent vulvovaginal candidosis (VVC and RVVC respectively), bacterial vaginosis (BV), and in pregnant and non-pregnant women without evidence of the three conditions. Also to compare the result of LE tests in women consulting at different weeks in the cycle and trimesters of pregnancy.The LE activity was correlated to vaginal pH, number of inflammatory cells in stained vaginal smears, type of predominating vaginal bacteria and presence of yeast morphotypes. Methods: One hundred and thirteen women with a history of RVVC, i.e. with at least four attacks of the condition during the previous year and who had consulted with an assumed new attack of the condition, were studied. Furthermore, we studied 16 women with VVC, 15 women with BV, and 27 women attending for control of cytological abnormalities, who all presented without evidence of either vaginitis or vaginosis. Finally, 73 pregnant women were investigated. The LE activity in vaginal fluid during different weeks in the cycle of 53 of the women was measured. Results: In the non-pregnant women, an increased LE activity was found in 96, 88, 73 and 56% of those with RVVC, VVC and BV and in the non-VVC/BV cases, respectively. In 73% of pregnant women in the second trimester, and 76% of those in the third, the LE test was positive. In all groups of non-pregnant women tested, the LE activity correlated with the number of leukocytes in vaginal smears, but it did not in those who were pregnant. There was no correlation between LE activity and week in cycle. The vaginal pH showed no correlation to LE activity in any of the groups studied. Conclusions: The use of commercial LE dipsticks has a limited value in the differential diagnosis of RVVC, VVCand BV. There is no correlation between the LE activity in vaginal secretion on one hand and vaginal pH, week in the menstrual cycle and trimester in pregnancy on the

    Zinc is an essential micronutrient and has significant effects on human growth, development, and immune function. Zinc supplementation or deficiency may affect the course of infection. Zinc enhances immune response against a wide range of viral, bacterial, and parasitic pathogens. In the present study, we investigated the effects of zinc sulphate (ZnSO(4)) supplementation (20mg/kg/day) during pregnancy in mice, Swiss Webster strain infected by the Y strain of Trypanosoma cruzi. Oral supplementation of zinc sulphate in pregnant and non-pregnant infected animals did not affect the count of blood parasites as well as tissue parasitism in the heart, liver, and spleen. Zinc supplementation did not alter female body weight, the length of fetuses and neonates, placental size/weight and mortality rate. Among zinc supplied animals, no significant plasmatic zinc concentrations were observed. Concerning to tissue zinc concentrations, only the liver displayed enhanced values as compared to other organs. For placental parasitism, zinc supplied group displayed a significant decrease in amastigote burdens (P<0.05). However due to the reduced number of parasite burdens in placenta of animals supplied with zinc, these data suggest that zinc was partially effective in up-regulating the host's immune response against parasite, probably attenuating the infection in fetuses.

    Analgesics which affect prostaglandin (PG) pathways are used by most pregnant women. As germ cells (GC) undergo developmental and epigenetic changes in fetal life and are PG targets, we investigated if exposure of pregnant rats to analgesics (indomethacin or acetaminophen) affected GC development and reproductive function in resulting offspring (F1) or in the F2 generation. Exposure to either analgesic reduced F1 fetal GC number in both sexes and altered the tempo of fetal GC development sex-dependently, with delayed meiotic entry in oogonia but accelerated GC differentiation in males. These effects persisted in adult F1 females as reduced ovarian and litter size, whereas F1 males recovered normal GC numbers and fertility by adulthood. F2 offspring deriving from an analgesic-exposed F1 parent also exhibited sex-specific changes. F2 males exhibited normal reproductive development whereas F2 females had smaller ovaries and reduced follicle numbers during puberty/adulthood; as similar changes were found for F2 offspring of analgesic-exposed F1 fathers or mothers, we interpret this as potentially indicating an analgesic-induced change to GC in F1. Assuming our results are translatable to humans, they raise concerns that analgesic use in pregnancy could potentially affect fertility of resulting daughters and grand-daughters. PMID:26813099

    Human leukocyte antigen-G which is an immune tolerance effecter molecule has an important role in the maintenance of fetus during pregnancy. Abortion is one of the complications of pregnancy period.  In this research, we have studied levels of HLA-G 5, HLA-G7 isoforms in the abortion-threatened pregnant women in comparison with controls. In a case-control study, 101 abortion-threatened women and 101 healthy pregnant women (healthy controls) with age range 21-32 years were studied. Gene expression of HLA-5 and HLA-7 isoforms was analyzed by real-time polymerase chain reaction after mRNA extraction and cDNA synthesis. The results indicated that HLA-G5 was significantly lower in abortion-threatened women in comparison with the control group whereas HLA-G7 was not significantly differentbetween the 2 groups. HLA-G is a vital molecule during pregnancy that can be a key factor in prevention of abortion. It is concluded that determination of HLA-G5 can be of value in pregnancy. PMID:25780888

    Circulating IGFs are important regulators of prenatal and postnatal growth, and of metabolism and pregnancy, and change with sex, age and pregnancy. Single-nucleotide polymorphisms (SNPs) in genes coding for these hormones associate with circulating abundance of IGF1 and IGF2 in non-pregnant adults and children, but whether this occurs in pregnancy is unknown. We therefore investigated associations of plasma IGF1 and IGF2 with age and genotype at candidate SNPs previously associated with circulating IGF1, IGF2 or methylation of the INS-IGF2-H19 locus in men (n=134), non-pregnant women (n=74) and women at 15 weeks of gestation (n=98). Plasma IGF1 concentrations decreased with age (P<0.001) and plasma IGF1 and IGF2 concentrations were lower in pregnant women than in non-pregnant women or men (each P<0.001). SNP genotypes in the INS-IGF2-H19 locus were associated with plasma IGF1 (IGF2 rs680, IGF2 rs1004446 and IGF2 rs3741204) and IGF2 (IGF2 rs1004446, IGF2 rs3741204 and H19 rs217727). In single SNP models, effects of IGF2 rs680 were similar between groups, with higher plasma IGF1 concentrations in individuals with the GG genotype when compared with GA (P=0.016), or combined GA and AA genotypes (P=0.003). SNPs in the IGF2 gene associated with IGF1 or IGF2 were in linkage disequilibrium, hence these associations could reflect other genotype variations within this region or be due to changes in INS-IGF2-H19 methylation previously associated with some of these variants. As IGF1 in early pregnancy promotes placental differentiation and function, lower IGF1 concentrations in pregnant women carrying IGF2 rs680 A alleles may affect placental development and/or risk of pregnancy complications.

    Although there has been long-standing reluctance to include pregnant women as clinical trial participants, increasing recognition of profound gaps in research on the safety and efficacy of drugs often prescribed to pregnant women calls into question the practice of routinely excluding them. This article presents compelling reasons for including pregnant women in clinical research, highlights certain regulatory barriers to the inclusion of pregnant women, and proposes that professional societies with expertise in obstetrics and maternal-fetal medicine can be instrumental in hastening the paradigm shift from the systematic exclusion of pregnant women in research to a one of responsible and fair inclusion.

    To determine the characteristics of pregnant women who use Ecstasy (3,4-methylenedioxymethamphetamine, MDMA), and to identify reproductive risk factors associated with this group of women. Prospective, observational study. Pregnant women who have contacted the Motherisk Alcohol and Substance Use Helpline at The Hospital for Sick Children, in Toronto, about exposure to drugs, chemicals, infection or radiation. All inquiries from December 1998 to October 2000 concerning pregnant women who reported use of MDMA, and control cases of women not exposed to MDMA selected within the same week of the MDMA callers. Age, maternal demographics, pregnancy characteristics, patterns of alcohol, tobacco, and illicit drug use, psychological/emotional status, sexually transmitted disease, MDMA method and pattern of use, and adverse drug reactions after ingestion of MDMA. The 132 pregnant women who used MDMA were significantly younger (mean 23.2 vs. 31.2 years, P<.0001), and had more unplanned pregnancies compared to 122 pregnant nonusers (84.2% vs. 54.3%, P<.05). MDMA users were also more likely to be single (57.0% vs. 18.3%, P<.001), and to be White (82.2% vs. 56.0%, P<.05). Comparably more MDMA users smoked cigarettes (53.8% vs. 19.7%, P<.0001), drank alcohol (66.4% vs. 37.3%, P<.0001), and had significantly more episodes of binge drinking during pregnancy (mean 2.12 vs. 0.05, P<.001). Illicit drugs such as cocaine, marijuana, methamphetamine, ketamine, gamma-hydroxy butyrate, and psilocybin were used more frequently among the MDMA sample. Over a third of MDMA users reported psychiatric/emotional problems, including 6.5% with a clinically diagnosed condition that was being treated with medication and/or counseling. Pregnant women who use MDMA tend to be young, single, and report psychological morbidity, and have a clustering of risk factors that may compromise the pregnancy and fetus. Smoking, heavy alcohol intake, and polydrug use, combined with a higher than expected rate of

    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.

    To guide anti-D prophylaxis, Dutch D- pregnant women are offered a quantitative fetal-RHD-genotyping assay to determine the RHD status of their fetus. This allowed us to determine the frequency of different maternal RHD variants in 37 782 serologically D- pregnant women. A variant allele is present in at least 0·96% of Dutch D- pregnant women The D- serology could be confirmed after further serological testing in only 54% of these women, which emphasizes the potential relevance of genotyping of blood donors. 43 different RHD variant alleles were detected, including 15 novel alleles (11 null-, 2 partial D- and 2 DEL-alleles). Of those novel null alleles, one allele contained a single missense mutation (RHD*443C>G) and one allele had a single amino acid deletion (RHD*424_426del). The D- phenotype was confirmed by transduction of human D- erythroblasts, consolidating that, for the first time, a single amino acid change or deletion causes the D- phenotype. Transduction also confirmed the phenotypes for the two new variant DEL-alleles (RHD*721A>C and RHD*884T>C) and the novel partial RHD*492C>A allele. Notably, in three additional cases the DEL phenotype was observed but sequencing of the coding sequence, flanking introns and promoter region revealed an apparently wild-type RHD allele without mutations.

    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.

    Sugar expressions were examined on the epithelium of both the middle portion of the vagina and the vaginal portion of the cervical canal (CC) in pregnant mice to understand the pathogenesis of bacterial infection in the female reproductive organ by using a panel of lectins. As a result, N-acetylglucosamine was positive before pregnant day (P) 7 but negative after P10 and at diestrus on both the vagina and the CC. In addition, some differences in sugar expressions were seen between them. These results suggest that sugar expressions on the mucosal surface would change not only site-specifically but also time-dependently, and these sugar differences indicate the possibility of the alteration of the settled bacterial species on the vaginal mucosa in pregnancy.

    We report a case of anaphylaxis in a 35+5 week of pregnancy patient who came to the Emergency Room with shortness of breath, hypotension and loss on fetal wellbeing. Due to her medical history and given the clinical picture at that time, an anaphylactic shock was suggested as the most probable diagnose. The administration of dexchlorpheniramine and methylprednisolone resulted in an immediate and positive reaction. Simultaneously, an improvement in the fetus cardiotocographic record was objectified. The patient was hospitalized for 48 hours, after which she was discharged. In case of suspicion of anaphylaxis in a pregnant woman, four aspects should be handled: the severity of the anaphylaxis chart, individual complications regarding a pregnant woman, unfavorable effects of the regularly used treatment during that specific gestation, and the need of fetal extraction based of gestational age.

    Malaria remains a complex problem during the pregnancy, which threatens > 35 millions pregnant women every year. Malaria pathogenesis in pregnancy results in accumulation of infected RBCs in the intervillous spaces causing severe alterations leading to the reduced materno-foetal exchanges. In this article we have revisited the current evidences of clinical implications and overall burden of malaria in pregnancy. Many adverse aftermaths including, low birth weight, intrauterine growth retardation, preterm delivery, stillbirth and anemia were found associated with malaria in pregnant women. Despite of worldwide comprehensive control programmes for malaria in pregnancy, the disease control has been a daunting task everywhere. Socio cultural, economical, lack of awareness and various logistic problems compound the disease in developing countries. Thorough evidence based information and estimates, education and awareness and strengthening of prevention programmes are needed urgently to achieve success in malaria control in pregnancy.

    Pregnant methamphetamine users who leave substance use treatment against professional advice may be at risk of poorer health outcomes. To examine the hypothesis that methamphetamine use during pregnancy may be associated with leaving substance use treatment against professional advice, the 2006 Treatment Episode Data Set was analyzed. A logistic regression adjusting for age, race, service setting, prior substance abuse treatment, criminal justice referral, and education was conducted. Inclusion criteria were met by 18,688 pregnant admissions; 26.4% identified methamphetamines as their primary substance of use. Frequency of use was identified as an effect modifier, therefore results were stratified by less than weekly use and weekly or more use. Methamphetamine use was significantly associated with leaving treatment against professional advice regardless of usage level. However, the odds of leaving treatment were greater among women using methamphetamine less than weekly. Further investigation into this association may be warranted due to the complications that may result from methamphetamine use during pregnancy.

    Progesterone is an essential hormone in the occurence and maintenance of pregnancy. Natural or synthetic progestogens are commonly used in pregnant patients or patients undergoing infertility treatments for various indications. Most frequently put indications for the use of progestogens in these patient populations are the prevention of spontaneous preterm birth, the prevention of pregnancy loss in pregnancies with an unexplained recurrent pregnancy loss and in patients with threatened abortion. It is also used in pregnant women undergoing nonobstetric surgery, for infertility or recurrent pregnancy loss that is thought to be due to luteal phase defect or as a luteal support in stimulated IVF cycles. We aimed to review the current evidence for the use of progestogens in each of these settings.

    A pregnant woman is exposed to a number of stress factors that can affect the pregnancy, maternal health and well-being of the foetus. Among these are the biological, social/environmental and psychological factors. The biological factors include medical condition of the pregnant woman, most notable is the gestational diabetes. The increased glucose levels can cause detrimental effect on the foetus and also cause maternal distress. This factor becomes more complicated if the woman is exposed to environmental stressors. The result is evident in the form of complications during pregnancy and psychological effects like depression and anxiety. Appropriate steps are important to address these issues in order to maintain the mother and prospective child\\'s well-being. PMID:27582167

    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.

    Background Improvements in antenatal vitamin D status may have maternal-infant health benefits. To inform the design of prenatal vitamin D3 trials, we conducted a pharmacokinetic study of single-dose vitamin D3 supplementation in women of reproductive age. Methods A single oral vitamin D3 dose (70,000 IU) was administered to 34 non-pregnant and 27 pregnant women (27 to 30 weeks gestation) enrolled in Dhaka, Bangladesh (23°N). The primary pharmacokinetic outcome measure was the change in serum 25-hydroxyvitamin D concentration over time, estimated using model-independent pharmacokinetic parameters. Results Baseline mean serum 25-hydroxyvitamin D concentration was 54 nmol/L (95% CI 47, 62) in non-pregnant participants and 39 nmol/L (95% CI 34, 45) in pregnant women. Mean peak rise in serum 25-hydroxyvitamin D concentration above baseline was similar in non-pregnant and pregnant women (28 nmol/L and 32 nmol/L, respectively). However, the rate of rise was slightly slower in pregnant women (i.e., lower 25-hydroxyvitamin D on day 2 and higher 25-hydroxyvitamin D on day 21 versus non-pregnant participants). Overall, average 25-hydroxyvitamin D concentration was 19 nmol/L above baseline during the first month. Supplementation did not induce hypercalcemia, and there were no supplement-related adverse events. Conclusions The response to a single 70,000 IU dose of vitamin D3 was similar in pregnant and non-pregnant women in Dhaka and consistent with previous studies in non-pregnant adults. These preliminary data support the further investigation of antenatal vitamin D3 regimens involving doses of ≤70,000 IU in regions where maternal-infant vitamin D deficiency is common.

    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

    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

    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.

    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.

    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.

    Objective To establish the Fe status of pregnant women and their neonates in the Republic of Seychelles. Design A prospective study. Setting Republic of Seychelles. Subjects Pregnant women were recruited and blood samples taken at enrolment and post-delivery along with cord blood samples. Ferritin and soluble transferrin receptor (sTfR) were measured in maternal (n 220) and cord blood (n 123) samples. Results Maternal Fe deficiency (ferritin<15 ng/ml, sTfR>28 nmol/l) was present in 6% of subjects at enrolment and in 20% at delivery. There was no significant decrease in maternal ferritin. A significant increase in sTfR was observed between enrolment and delivery (P<0·001). Maternal BMI and use of Fe supplements at 28 weeks’ gestation were associated with improved maternal Fe status at delivery, whereas parity had a negative effect on sTfR and ferritin at delivery. Conclusions Fe status of pregnant Seychellois women was, on average, within normal ranges. The incidence of Fe deficiency throughout pregnancy in this population was similar to that in a Westernised population. Increased awareness of the importance of adequate Fe intake during pregnancy, particularly in multiparous women, is warranted. PMID:19706210

    There is the report that the deaths by pellagra in women is approximately twofold excess that in men. In the present experiment, in order to clarify a factor in the etiology of pellagra in female and to get basic information how much niacin should be supplemented in pregnant state, we investigated the effects of pregnant on the metabolism of tryptophan to niacin in rats. The daily urine samples were collected from day -17 and day +6 (the delivery day was designated as day 0) and the intermediates of tryptophan to niacin were measured. The metabolites such as kynurenic acid, xanthurenic acid, anthranilic acid, 3-hydroxyanthranilic acid, quinolinic acid, N1-methylnicotinamide, N1-methyl-2-pyridone-5-carboxamide, N1-methyl-4-pyridone-3-carboxamide were increased with progress in pregnant and returned to normal levels after the delivery. The catabolism of tryptophan is accelerated during pregnancy, indicataing that pregnancy would not be an etiology of pellagra and no niacin supplement needs but tryptohan supplement would need.

    Pregnant women with an ostomy face many challenges during the prenatal period. Although these challenges may be present, pregnancy in the ostomate is presented as a continuum of health and wellness in this article. Collaborative care professionals, especially nurses and midwives, are often the most accessible professional sources for health care information, but current research and information on this topic is sparse. Ostomy-related problems that may occur during pregnancy, include: intestinal obstruction, peristomal hernia, pouching problems, including the effect of nausea and vomiting on pouch hydration, stomal retraction, stenosis, or laceration, and stomal prolapse. Three types of ostomies are discussed: continent ileostomies, urostomies and colostomies. A description of the normal characteristic appearance of each is also included. Collaborative care from pre-conception through the post partum period is described with emphasis on teaching self-help techniques such as: special nutritional considerations, how to recognize potential problems, and how to fit and adapt appliances to the changing body form of the patient as the pregnancy progresses. Phenomenologic information about the pregnant ostomate's perceptions about her pregnancy experience is also presented. Psycho-prophylaxis methods of complementary therapy alternatives alleviating nausea and vomiting within pregnancy, as well as the pain of childbirth are also presented. Although nursing/midwifery management of a pregnant ostomy patient is a challenge, those challenges are surmountable and outcomes resemble those found in the general population.

    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. PMID:27277362

    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

    2013-08-01

    Pregnancy in opioid users poses a number of problems to treating physicians. Most guidelines recommend maintenance treatment to manage opioid addiction in pregnancy, with methadone being the gold standard. More recently, buprenorphine has been discussed as an alternate medication. The use and efficacy of buprenorphine in pregnancy is still controversial. This article reviews the current database on the basis of a detailed and critical literature search performed in MEDLINE (206 counts). Most of the relevant studies (randomised clinical trials and one national cohort sample) were published in the last 2 years and mainly compared buprenorphine with methadone. Some studies are related to maternal outcomes, others to foetal, neonatal or older child outcomes. With respect to maternal outcomes, most studies suggest that buprenorphine has similar effects to methadone. Very few data from small studies discuss an effect of buprenorphine on neurodevelopment of the foetus. Neonatal abstinence syndrome is common in infants of both buprenorphine- and methadone-maintained mothers. As regards neonatal outcomes, buprenorphine has the same clinical outcome as methadone, although some newer studies suggest that it causes fewer withdrawal symptoms. Since hardly any studies have investigated the combination of buprenorphine with naloxone (which has been suggested to possibly have teratogenic effects) in pregnant women, a switch to buprenorphine monotherapy is recommended in women who become pregnant while receiving the combination product. These novel findings indicate that buprenorphine is emerging as a first-line treatment for pregnant opioid users. PMID:23775478

    Pertussis may cause death in neonates and very young infants. In these ages pertussis vaccine has not been administered yet or infants haven't received enough doses of vaccine to protect them. Cocoon strategy have been implemented in several countries and has limited efficacy because of low coverage among households. In vaccinated pregnant women transplacental transfer of pertussis antibodies starts at 32-34 weeks of pregnancy. United Kingdom, The United States of America and afterward other countries in Europe and America have adopted this strategy. Recent British research about security and effectiveness of pertussis vaccination in pregnant women to reduce pertussis incidence and fatality cases in neonate and very young infants infant support this strategy despite the fact that controlled studies about the efficacy and security in mothers and neonates have not been published. Several studies still not published or in progress are trying to answer these two questions and to evaluate possible interference between transplacentaly transferred pertussis antibodies and infants immune response to routine vaccines. Recently WHO has recommended pertussis vaccination during pregnancy in countries where neonatal pertussis is a public health problem. Nowadays, Chilean experts discuss if pertussis vaccination of pregnant women must be adopted in our country.

    The combination of heart disease and pregnancy can present a formidable challenge to the clinician entrusted to care for both the mother and fetus. Since most data is retrospective, a definitive prognosis for such a patient may be difficult to obtain. Nevertheless, certain cardiac conditions carry greater risks of maternal mortality than do others. However, even for certain preexisting conditions, a tremendous amount of debate persists with respect to risks during pregnancy and optimal peripartum management. One such area of controversy concerns anticoagulation in pregnant women with prosthetic heart valves. For patients who require anticoagulation for mechanical valves, the choice of some combination of warfarin, unfractionated heparin, and low-molecular-weight heparin (LMWH) has resulted in many small-scale trials, which have not yet provided definite guidance as to the best course of action. Even more controversial has been the recent labeling change that advises against the use of LMWH in all patients with prosthetic heart valves, as a result of two cases of prosthetic valve thrombosis in women using LMWH while pregnant. Although the latest product labeling, in the summer of 2003, was changed to a less restrictive recommendation, debate persists. A discussion of the available data on anticoagulation in pregnant women with prosthetic heart valves is presented here, to inform the clinician and the patient of the risks and benefits of the options presently available.

    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.

    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. PMID:26488781

    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.

    2006-04-12

    The seroprevalence and the risk of perinatal transmission of rubella virus (RV) and human parvovirus B19 were assessed in 439 Jordanian pregnant women. Seroprevalence data indicate that 43.7%, 48.7% and 19% of women are susceptible to RV, parvovirus B19 infections and both, respectively. A total of 12.2% and 20.2% of RV susceptible women are at the first and second trimester of gestation, respectively. They are at risk of bearing infants with congenital rubella syndrome (CRS). However, 15% and 23% of parvovirus B19 susceptible women are at the first and second trimester of gestation, respectively. They are at risk of fetal loss or hydrops fetalis. Prenatal screening for these viruses, postpartum MMR vaccination and parvovirus B19 passive immunization are recommended. PMID:16460842

    Several decades ago, diethylstilbestrol (DES) was prescribed to support the pregnancy of women who were diabetic, who had had consecutive abortions, or who were threatening to abort. The use of this estrogen substitute to support human gestation had ceased by the 1960s. In 1971, the first report was published in which DES exposure was linked with clear cell carcinoma of the vagina and cervix. Since then, many other documentations have been published on upper genital tract anomalies, poor reproductive performance, and the high incidence of fetal wastage in DES-exposed women. The author describes a case of clear cell carcinoma of the kidney in an 18-year-old pregnant woman with a prior history of vaginal adenosis who had been exposed to DES in utero.

    Rift Valley fever (RVF) causes abortion in sheep and cattle. However, the teratogenic and abortogenic potential of RVF in humans is not known. Sera from a total of 1163 pregnant women in Mozambique were tested for RVF virus antibodies by ELISA and 28 (2%) were found to be positive. Mothers experiencing fetal death or miscarriage (155) had the same RVF virus antibody prevalence as those with normal deliveries. Analysis of maternity histories showed some indication of increased fetal wastage among women positive for RVF virus antibody. The ELISA used in this study was compared with a plaque reduction neutralization test and found to be equally sensitive and specific for the detection of RVF virus IgG antibodies. PMID:3678406

    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.

    The objective of this study was to assess the iodine status of pregnant women in a metropolitan city which was stated as iodine sufficient area after salt iodination program. This multicenter, cross-sectional study was carried out on 3543 pregnant women. Age, gestational weeks, smoking, consumption of iodized salt, dietary salt restriction, history of stillbirth, abortus and congenital malformations were questioned. Spot urine samples were analyzed for urine iodine concentration (UIC). The outcomes were: (a) median UIC in three trimesters of pregnancy and (b) frequency of ID among pregnant women. The median UIC was 73 µg/L. The median UIC was 77 µg/L (1-324), 73 µg/L (1-600) and 70 µg/L (1-1650) in three trimesters of pregnancy, respectively (p: 0.14). UIC <50 µg/L was observed in 36.6% (n: 1295) and UIC<150 µg/L was observed in 90.7% (n: 3214) of pregnant women. Only 1% (n: 34) of the pregnant women had UIC levels higher than 500 µg/L. This study showed that more than 90% of the pregnant women in this iodine-sufficient city are facing some degree of iodine deficiency during their pregnancy. A salt iodization program might be satisfactory for the non-pregnant population, but it seems to be insufficient for the pregnant population.

    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.

    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.

    This study sought to compare the perception of domestic violence of women, victims of this kind of violence, with the perception of pregnant women, victims or not of domestic violence, as well as to search for elements allowing for the planning and execution of a cohort study on domestic violence among pregnant women. A qualitative exploratory research was conducted using the technique of convenience sampling for selecting a focal group. The subjects were twenty four women divided into two groups: (1) thirteen women from a follow-up group from a Referral Center for victims of domestic violence, and (2) eleven pregnant women that were participating in the pre-natal care program in a primary care unit, selected independently of suffering domestic violence or not. The data collected were transcribed, conceptually decoded and qualified for qualitative analysis. The contents of the women's discourse were analyzed on the basis of thematic categories. It was observed that domestic violence was perceived in a similar way by both studied groups, independently from the fact of having or not experienced a situation of this kind. The understanding and discussion of the topics proposed for the groups allowed developing a more appropriate approach to the studied women. The way the questions were formulated in the questionnaire was considered of easy understanding by both groups of 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.

    The effect of beryllium (Be) compounds on porphyrins was investigated in pregnant mice. The blood protoporphyrin (Proto) and zinc protoporphyrin (Zn Proto) concentrations were increased in pregnancy. Regardless of pregnancy or nonpregnancy, the Proto concentration was decreased after Be injection. Delta-aminolevulinic acid dehydratase (ALA-D) and porphobilinogen deaminase (PBG-D) activities in blood were significantly elevated in the pregnant untreated (Con-pregnant) group, compared to the nonpregnant mice untreated (Con-nonpregnant) and nonpregnant mice treated with Be (Be-nonpregnant) groups. The blood ALA-D activity of the pregnant mice treated with Be (Be-pregnant group) tended to decrease, compared to Con-pregnant group. The blood PBG-D activity in the Be-pregnant group was significantly lower compared with that of the Con-pregnant group. The ALA-D and PBG-D activities in the spleen were also significantly elevated in the Con-pregnant group, compared to nonpregnant groups. However, it was noted that these values in the Be-pregnant group were almost the same as that of the Con-nonpregnant group and were significantly lower than that in the Con-pregnant group. The elevation of AL-D and PBG-D activities in the blood and spleen, which play a role in the hematopoietic function of mice, was observed in the Con-pregnant mice compared to the nonpregnant mice. However, the phenomenon was not observed in the Be-pregnant mice, it suggesting that Be suppressed the pregnancy-induced increase in hematopoietic function. 26 refs., 3 figs., 2 tabs.

    The rate of HBsAg in 6,976 B-human chorionic gonadotropin (B-hCG)-positive specimens, as determined by the Auszyme Monoclonal assay (Abbott Laboratories, Abbott Park, Ill.), was 0.56% (39 of 6,986 repeatedly reactive [RR] and confirmed-positive specimens). All RR and confirmed specimens were hepatitis B virus positive by at least one additional test, yielding an assay specificity of 99.96%. The findings argue against unique attributes in the pregnant population that might produce inaccurate assay results. PMID:12202601

    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

    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

    Ochratoxin A (OTA) and citrinin (CIT) are both nephrotoxic and teratogenic in animals, and the occurrence of these mycotoxins in food may cause adverse health effects in humans. Data on the combined exposure to these food contaminants are still scarce, especially in pregnancy. Therefore, a biomonitoring study was conducted to determine the presence of urinary biomarkers of exposure to OTA and CIT in pregnant women in Bangladesh. In total, 54 spot urine samples were collected from residents of a rural and a suburban area of the Savar region in Dhaka district for analysis of OTA and CIT urinary biomarkers by previously validated HPLC-FD and LC-MS/MS methods. Most urines were positive for OTA and CIT biomarkers, with OTA being detected in 93 % (range 0.01-0.84 ng/mL) and CIT biomarkers in 87 % (range 0.02-6.93 ng/mL) of all samples. The mean levels of OTA were different between the rural (0.06 ± 0.07 ng/mL) and suburban (0.15 ± 0.19 ng/mL) study participants. CIT and its metabolite dihydrocitrinone (HO-CIT) were more than twofold higher in the rural (0.42 ± 1.20 and 0.55 ± 1.04 ng/mL, respectively) than the suburban (CIT 0.15 ± 0.13 ng/mL; HO-CIT 0.23 ± 0.18 ng/mL) participants. When a provisional daily intake for CIT was calculated, it exceeded the preliminary tolerable value set by European Food Safety Authority (0.2 μg/kg/day) in 9 % of the rural participants but in none of the urban participants. Urinary biomarker levels for OTA and CIT did not show significant association with intake of certain types of food consumed by the pregnant women, although total CIT biomarker levels were considerably higher among participants who consumed more rice in a day. Overall, this study indicates a frequent co-exposure to OTA and CIT among pregnant women in Bangladesh, at levels similar to those determined recently in the general population of this country.

    Background Luteal activity is dependent on the interaction of various growth factors, cytokines and hormones, including the thyroid hormones, being that hypo- and hyperthyroidism alter the gestational period and are also a cause of miscarriage and stillbirth. Because of that, we evaluated the proliferation, apoptosis and expression of angiogenic factors and COX-2 in the corpus luteum of hypo- and hyperthyroid pregnant rats. Methods Seventy-two adult female rats were equally distributed into three groups: hypothyroid, hyperthyroid and control. Hypo- and hyperthyroidism were induced by the daily administration of propylthiouracil and L-thyroxine, respectively. The administration began five days before becoming pregnant and the animals were sacrificed at days 10, 14, and 19 of gestation. We performed an immunohistochemical analysis to evaluate the expression of CDC-47, VEGF, Flk-1 (VEGF receptor) and COX-2. Apoptosis was evaluated by the TUNEL assay. We assessed the gene expression of VEGF, Flk-1, caspase 3, COX-2 and PGF2α receptor using real time RT-PCR. The data were analyzed by SNK test. Results Hypothyroidism reduced COX-2 expression on day 10 and 19 (P < 0.05), endothelial/pericyte and luteal cell proliferation on day 10 and 14 (p < 0.05), apoptotic cell numbers on day 19 (p < 0.05) and the expression of Flk-1 and VEGF on day 14 and 19, respectively (p < 0.05). Hyperthyroidism increased the expression of COX-2 on day 19 (P < 0.05) and the proliferative activity of endothelial/pericytes cells on day 14 (p <0.05), as well as the expression of VEGF and Flk-1 on day 19 (P < 0.05). Conclusions Hypothyroidism reduces the proliferation, apoptosis and expression of angiogenic factors and COX-2in the corpus luteum of pregnant rats, contrary to what is observed in hyperthyroid animals, being this effect dependent of the gestational period.

    Background Although disaster causes distress, many disaster victims do not develop long-term psychopathology. Others report benefits after traumatic experiences (post-traumatic growth). The objective of this study was to examine demographic and hurricane-related predictors of resilience and post-traumatic growth. Methods 222 pregnant southern Louisiana women were interviewed, and 292 postpartum women completed interviews at delivery and eight weeks later. Resilience was measured by scores lower than a non-affected population, using the Edinburgh Depression Scale and the Post-Traumatic Stress Checklist (PCL). Post-traumatic growth was measured by questions about perceived benefits of the storm. Women were asked about their experience of the hurricane, addressing danger, illness/injury, and damage. Chi-square tests and log-Poisson models were used to calculate associations and relative risks (RR) for demographics, hurricane experience, and mental health resilience and perceived benefit. Findings 35% of pregnant and 34% of the postpartum women were resilient from depression, while 56% and 49% were resilient from post-traumatic stress disorder. Resilience was most likely among white women, older women, and women who had a partner. A greater experience of the storm, particularly injury/illness or danger, was associated with lower resilience. Experiencing damage due to the storm was associated with increased report of some perceived benefits. Conclusions Many pregnant and postpartum women are resilient from the mental health consequences of disaster, and perceive benefits after a traumatic experience. Certain aspects of experiencing disaster reduce resilience, but may increase perceived benefit. PMID:20123173

    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.

    AIM: The aim of this study was to assess the prevalence of chlamydial infection among pregnant women and to determine the role of this infection in the fetus. MATERIAL AND METHODS: In the first phase of this study were reported 58 pregnant women with a positive test for active chlamydial infection by applying immunofluorescence. In the second phase of the study were reported pregnant with premature burst membranes (PBM), postnatal complications associated with chlamydial infection as puerperal endometritis, and newborns are monitored for low birth weight and growth retardation at birth. RESULTS: With a positive test are 58 patients in the first trimester or pregnancy registration in our consultation. After regimen with Sumamed (2 x 500 mg for three days and after 10 days again same scheme for them and their partner) at the beginning of the third trimester, the PCR test was made again. Of these, 5 were positive again, participants are between 20 and 30 years old. With premature rupture of OM are 20 patients. There was no increased incidence of premature births. Infants born to infected mothers have a higher risk of developing respiratory symptoms in the first 60 days of life. 3 of them have low for his age bodyweight. CONCLUSIONS: The scarcity of data on manifestations of chlamydial infection during pregnancy and neonatal outcomes justifies this study. Early diagnosis for registration of pregnancy and timely treatment of chlamydial infection as well as scrutinising the infection during the third trimester of pregnancy can prevent infection of the newborn. Therefore, preventive examinations should be considered as a priority for early detection of asymptomatic chlamydial infection in the conduct of antenatal care. PMID:27703564

    Abstract Background: This observational study followed a cohort of pregnant women during the 2010–2011 influenza season to determine factors associated with vaccination. Methods: Participants were 1105 pregnant women who completed a survey assessing health beliefs related to vaccination upon enrollment and were then followed to determine vaccination status by the end of the 2010–2011 influenza season. We conducted univariate and multivariate analyses to explore factors associated with vaccination status and a factor analysis of survey items to identify health beliefs associated with vaccination. Results: Sixty-three percent (n=701) of the participants were vaccinated. In the univariate analyses, multiple factors were associated with vaccination status, including maternal age, race, marital status, educational level, and gravidity. Factor analysis identified two health belief factors associated with vaccination: participant's positive views (factor 1) and negative views (factor 2) of influenza vaccination. In a multivariate logistic regression model, factor 1 was associated with increased likelihood of vaccination (adjusted odds ratio [aOR]=2.18; 95% confidence interval [CI]=1.72–2.78), whereas factor 2 was associated with decreased likelihood of vaccination (aOR=0.36; 95% CI=0.28–0.46). After controlling for the two health belief factors in multivariate analyses, demographic factors significant in univariate analyses were no longer significant. Women who received a provider recommendation were about three times more likely to be vaccinated (aOR=3.14; 95% CI=1.99–4.96). Conclusion: Pregnant women's health beliefs about vaccination appear to be more important than demographic and maternal factors previously associated with vaccination status. Provider recommendation remains one of the most critical factors influencing vaccination during pregnancy. PMID:25874550

    Introduction: Throughout the Eastern Mediterranean region, tobacco is used primarily in 2 forms: cigarette smoking and waterpipe smoking. Despite the fact that tobacco use is considered as a global public health threat, waterpipe smoking is reported to be growing in popularity, particularly among women. The objectives of this study are to determine the prevalence and patterns of cigarette, waterpipe, and passive smoking among pregnant women in Jordan, and to assess their perception of harmful effects of cigarette and waterpipe smoking. Methods: A total of 500 pregnant women were randomly recruited from maternity clinics in North and Middle of Jordan and surveyed regarding exposure to waterpipe tobacco and cigarette smoking. Results: The results showed that 7.9% of women were current cigarette smokers and 8.7% were current waterpipe smokers. About 82.4% of all women reported that they are exposed to cigarette smoke and 32.8% reported that they are exposed to waterpipe smoke. The most common place where women are exposed to cigarette and waterpipe smoke was their house (50.4% and 48.7%, respectively) followed by public places (31.4% and 21.4%, respectively). In addition, the husband was the main source for exposure to cigarette and waterpipe smoke (48.5% and 42.7%, respectively). Approximately, 74% of women believed that cigarette smoking is addictive, whereas only 55.1% reported that waterpipe smoking leads to addiction. Conclusions: Exposure of pregnant women to tobacco smoke is a public health problem in Jordan that requires immediate action. PMID:22573726

    Cytokines present in the reproductive system play an important role both in the modulation of immune responses to infectious challenge and in the establishment and maintenance of pregnancy. Interleukin 18 (IL-18) has been regarded as an important regulator of innate and acquired immune response, but its expression and distribution in the hypothalamic-pituitary-ovarian axis remain unclear. In this paper, the expression and distribution of IL-18 in non-pregnant, pregnant, and early abortive rats were examined using an ultra-sensitive immunohistochemical streptavidin-peroxidase method, enzyme-linked immunosorbent assay, and reverse transcription-polymerase chain reaction. The results showed that IL-18 expression in the pituitary, in follicular ovaries, and in the corpus luteum of abortive rats were significantly lower than that of pregnant and non-pregnant rats. However, the staining of IL-18 in the hypothalamus, interstitial glands of the ovary, and uterus of abortive rats was strikingly stronger than those of the non-pregnant ones. IL-18 mRNA expression in rat uterus was detected in all groups, whereas IL-18 mRNA content in abortive rat uterus was significantly higher than in normal pregnant rats. Further, IL-18 in the peripheral blood serum of abortive rats was significantly lower than in same-period normal pregnant rats. The differential expression of IL-18 in early abortion suggests that IL-18 may be related to the underlying mechanisms of abortion.

    Serum concentrations of relaxin and progesterone were measured by specific radioimmunoassays in pregnant, pseudopregnant, or ovariectomized (between gestation weeks 4 and 5) pregnant Labrador Retriever bitches. Daily administration of 17 alpha-ethyl-19-nortestosterone was performed to maintain gestation in the ovariectomized pregnant bitches. This synthetic gestagen was selected because it did not interfere with the assay for endogenously secreted progesterone concentration in serum. Serum progesterone concentration was high in ovarian-intact pregnant or pseudopregnant bitches, but the mean progesterone concentration in pseudopregnant bitches (evaluated at 4 weeks after mating) was only 56% of the concentration in pregnant bitches. After ovariectomy, serum progesterone concentration decreased to undetectable values. Unlike progesterone, serum relaxin concentration increased during the latter half of pregnancy in the ovarian-intact and in the ovariectomized pregnant bitches, but relaxin was not detectable at any time in the pseudopregnant bitches. The amount of relaxin measured in the ovariectomized pregnant bitches was less (P less than 0.05) than that in ovarian-intact bitches, suggesting that the ovaries may have contributed to the total circulating relaxin concentration in the latter. Placental production of relaxin might have accounted for the serum relaxin concentration after ovariectomy; thus, the ovary and placenta each may secrete relaxin during gestation in bitches. Regardless of its source, measurement of serum relaxin concentration may offer a useful way of distinction between pregnancy and pseudopregnancy in dogs.

    The authors describe their experience in the follow-up of four patients with chronic renal failure who became pregnant while being treated with chronic hemodialysis. The outcomes were successful and each gave birth to healthy babies. The adequate nutritional condition previous to the pregnancies added more safety to their management. Special dedication to the nutritional control enabled a good outcome of their pregnancies. It stressed the importance of the intervention of the nutritionist-dietitian in the follow-up of nephrologic patients and the integration of a multidisciplinary staff. PMID:9724505

    This case report describes a pregnant woman of gestational week 37 + 2 days who was admitted to the hospital with first-time seizures. The patient was stabilized, and an acute caesarian section was performed due to the possible aetiology of eclampsia and the advanced gestational age. Because of the atypical clinical history and normal maternal blood samples a computed tomography of the cerebrum was performed demonstrating a subarachnoid haemorrhage. A computed tomography-angiography revealed an aneurism at the anterior communicating artery. The aneurism was coiled the following day to reduce the risk of rebleeding. PMID:27460576

    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. Conclusions Pregnant women have some oral health knowledge. Knowledge varied according to maternal race or

    Recent evolving trends in the United States legal system regarding how policies and laws are applied to pregnant women include concerns over the use of restraints or shackles in pregnant inmates and forced treatment or commitment of pregnant women for substance abuse. These topics raise many questions, such as: how violent are women, particularly pregnant women; what are the informed consent and treatment implications; and who is at risk of harm? In addition, questions have been raised regarding maternal versus fetal rights, especially when the mother uses substances during a pregnancy. We review legal decisions and organizational position statements and highlight ethics-related concerns. PMID:26438814

    Objective The objective of this study was to determine the effect of body mass index (BMI) during pregnancy in laboratory parameters in the serum of the three groups of pregnant women and in their newborns. Methods This prospective study is comparison between the three groups of pregnant women and their newborns categorized according to their BMI. The study included 128 pregnant women and their newborns. In this study, the concentration of blood count, iron, ferritin, and bilirubin were analyzed in the subjects. Results The pregnant women in the three groups significantly differ in the values of blood count (p < 0.001). Statistically significant difference in iron and ferritin was not found between individual three studied groups of pregnant women (p = 0.947). The newborn of the first group of pregnant women had significantly lower values of ferritin (p < 0.001), leucocytes (p < 0.001), and bilirubin (p < 0.001). Significant positive correlation between BMI of pregnant women and leucocytes, ferritin, and bilirubin of the newborn was found (p < 0.001). Conclusion In this study, the tested pregnant women do not have biochemical signs of anemia, neither do their newborns. It was noted that there was no negative correlation between individual tested biochemical parameters for anemia in pregnant women and their newborns. PMID:27119047

    The aim of this study was to use the fluorescence in situ hybridization (FISH) technique to test the hypothesis of qualitative and quantitative differences of 8 periodontopathogens between pregnant and non-pregnant women. This cross-sectional study included 20 pregnant women in their second trimester of pregnancy and 20 non-pregnant women. Probing depth, bleeding on probing, clinical attachment level, and presence of calculus were recorded. Subgingival plaque samples were collected and the FISH technique identified the presence and numbers of Aggregatibacter actinomycetemcomitans, Tannerella forsythia, Campylobacter rectus, Porphyromonas gingivalis, Treponema denticola, Fusobacterium nucleatum, Prevotella intermedia and Prevotella nigrescens. The Mann-Whitney U-test was applied to compare the data between the two groups. The mean age, ethnicity, marital status, education, and economic level in both groups were similar. The clinical parameters showed no significant differences between pregnant and non-pregnant women. The numbers of subgingival periodontopathogens were not found to be significantly different between groups, despite the higher mean counts of P. intermedia in pregnant women. Colonization patterns of the different bacteria most commonly associated with periodontal disease were not different in the subgingival plaque of pregnant and non-pregnant women.

  18. Urinary metabolites of organophosphate flame retardants and their variability in pregnant women.

    Organophosphate flame retardants (OPFRs) are commonly added to consumer products to reduce their flammability. Based on levels of OPFRs in indoor environments, human exposure is likely chronic and ubiquitous. Animal studies suggest that exposure to some OPFRs may result in adverse health impacts, particularly for Tris (1,3-dichloropropyl) phosphate (TDCPP); however, human data on the impacts of exposure to OPFRs are lacking. To design human studies, more information is needed on the stability of measured OPFRs in human samples over time. In this study, we sought to assess the degree of temporal variability of urinary TDCPP and triphenyl phosphate (TPP) metabolites throughout pregnancy in a cohort of women from central North Carolina. Eight pregnant women provided multiple urine samples: 3 during the 18th week of pregnancy, 1 during the 28th week, and 1 shortly after the child's birth. Bis (1,3-dichloropropyl) phosphate (BDCPP) and diphenyl phosphate (DPP), the respective metabolites of TDCPP and TPP, were measured in urine samples using liquid chromatography-tandem mass spectrometry. BDCPP and DPP were each detected in 38 of 39 urine samples and were not normally distributed. Geometric mean BDCPP and DPP concentrations were 1.3ng/mL (interquartile range (IQR): 0.8, 2.7ng/mL) and 1.9ng/mL (IQR: 0.9, 3.5ng/mL), respectively. BDCPP and DPP were moderately to strongly reliable over one week (intraclass correlation coefficient (ICC)=0.5; 95% confidence interval (CI): 0.4, 0.7 and ICC=0.7; 95% CI: 0.5, 0.8, respectively), and over the entire pregnancy (ICC=0.5 95% CI: 0.3, 0.7 and ICC=0.6; 95% CI: 0.4, 0.7, respectively). These data suggest that exposures to TDCPP and TPP are widespread and variable for pregnant women, and that a single measure of BDCPP or DPP, taken in the second trimester, likely captures information on the rank order of exposure throughout pregnancy.

    Many prescription medications have limited information regarding safety for use during pregnancy. In order to inform research on safer medication use during pregnancy, we examined prescription medication use among women in the United States. We analyzed data from the 1999-2006 National Health and Nutrition Examination Survey (NHANES) to estimate the prevalence of prescription medication use in the past 30 days among pregnant women and non-pregnant women of childbearing age (15-44 years) and to ascertain the most commonly reported prescription medications by women in these groups. We assessed how the most commonly reported medications differed among groups defined by selected demographic characteristics, including age, race/ethnicity, and markers of socioeconomic status. Prescription medication use in the past 30 days was reported by 22 % of pregnant women and 47 % of non-pregnant women of childbearing age. The most commonly reported prescription medications by NHANES participants differed somewhat by pregnancy status; allergy and anti-infective medications were more common among pregnant women, while oral contraceptives were more common among non-pregnant women. Use of prescription medication for asthma and thyroid disorders was reported by both groups. Although prescription medication use in the previous 30 days was less common among pregnant women than non-pregnant women, its use was reported among almost 1 in 4 pregnant women. Many of the most common medications reported were for the treatment of chronic medical conditions. Given the potential impact of medications on the developing fetus, our data underscore the importance of understanding the safety of these medications during pregnancy.

    Background Adverse pregnancy outcomes are undesirable events occurring during pregnancy and childbirth in mother or child, such as Preterm Low Birth Weight (PLBW) and preeclampsia. There is growing evidence that periodontitis may be a risk factor for preterm birth even after adjusting for known risk factors. Aim 1. To determine the knowledge and attitude of pregnant females about oral health. 2. To evaluate the oral hygiene practices of pregnant females. 3. To evaluate their awareness regarding effect of oral health on adverse pregnancy outcomes. 4. To assess whether there was any significant difference from their non pregnant counter parts. 5. To evaluate whether their awareness towards dental treatment had increased after conceiving. Materials and Methods 200 pregnant and 200 non-pregnant women filled up a validated questionnaire which comprised of questions on personal data, oral hygiene knowledge, attitude, oral hygiene practices and their awareness regarding the correlation of oral health to adverse pregnancy outcomes. Statistical Analysis Analyses were conducted using SPSS for Windows (version 15.0; SPSS Inc., Chicago, IL, USA). Results The results indicate no statistically significant differences in the variables assessed in both the groups, indicating that no further knowledge had been imparted to the women after they conceived. 96% women of both groups (p>0.05) had received no knowledge from the gynaecologist regarding the impact of oral health on pregnancy outcomes. 93.9% of pregnant women, and 89.5% of non pregnant women (p>0.05) did not go for routine dental check-ups. Only 3% of pregnant women were aware of oral health having a correlation with adverse pregnancy outcomes. Conclusion In our study, pregnancy did little to change future attitudes to dental care. To provide better oral health care, more knowledge needs to be made available to the pregnant women and the medical community. PMID:26674176

    PBDEs are a class of brominated flame retardants applied to consumer goods to reduce their flammability. These compounds are lipophilic, persistent and bioaccumulate through the food web. PBDEs have been detected in human blood, adipose tissue and breast milk. There are a small number of studies reporting concentrations of PBDEs in Australian populations. These indicate that concentrations are higher than in studies reporting concentrations from Europe but lower than those from Northern America. The aim of this paper was to determine the concentrations of PBDEs in the plasma of pregnant women participating in the Australian Maternal Exposure to Toxic Substances (AMETS) study in Western Australia. The samples comprised 164 pregnant women, aged 18 years and over, who were non-smokers and not occupationally exposed to persistent substances. Participants provided blood samples at 38 weeks gestation and these were analysed for five PBDE congeners. Maternal health and birth outcomes data were also obtained. The median for sum PBDE concentrations in plasma was 53.9 pg g(-1) (range 13.2 to 1390 pg g(-1)ww). Concentrations were adjusted for the estimated plasma lipid content. The concentrations of Σ5PBDE ranged from 2.44 to 258 ng g(-1) lipid with a median of 9.97 ng g(-1) lipid. BDE-47 was the dominant congener (median 21.4 pg g(-1), range <4.95 to 1030 pg g(-1)) followed by BDE-153 (median 12.2 pg g(-1), range <2.94 to 353 pg g(-1)). There were no significant associations between maternal, housing or dietary factors and concentrations of PBDEs in this study. Maternal PBDE concentrations were not associated with infant birth weight. This study builds upon previous Australian research and shows that concentrations in this sample of Western Australian women were higher than in parts of Europe. PMID:24973935

    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

    Cytomegaloviruses (CMV) are ubiquitous and species-specific. Humans are believed to be the only reservoir of this virus and transmission occurs by direct or indirect person-to-person contact. Vertical transmission can lead to serious congenital infections. Rubella virus causes serious disease after vertical transmission but mostly remain subclinical or cause a trivial infection that may remain unrecognized. The objective of our study was to find the prevalence of CMV and rubella infection in the vulnerable section of our population attending GTB hospital. GroupI included pregnant women with bad obstetric history (BOH) (n=1115); GroupII normal pregnant women (n=500); Group III pediatric age group (n==585) and Group IV others with varied illness (n=100). Serologically IgM antibodies against CMV and rubella were detected using commercially available Elisa kit. The percentage prevalence in groupI was (11%) and (3.6%); groupII was (4%) and (0); groupIII was (12%) and (3%); group IV was (5%) and (1%) against CMV and rubella respectively. No apparent seasonal variation was observed in the pattern of infection. Also, overall infection rates were at a much lower rate as compared to other studies. Therefore the detection of IgM antibodies in early pregnancy is an important tool to identify active infection and to provide obstetric management to avoid the risk of congenital transmission of infection. This in turn may lead to a rethinking of current immunization strategies and appropriate modifications for the prevention of vertical infection. PMID:18338691

    Fentanyl is used for pain treatment during pregnancy in human beings and animals. However, fentanyl pharmacokinetics during pregnancy has not been fully established. The aim of this study was to characterize fentanyl pharmacokinetics in pregnant sheep after intravenous and transdermal dosing during surgical procedure performed to ewe and foetus. Pharmacokinetic parameters reported for non-pregnant sheep and nominal transdermal dose rate were utilized for a priori calculation to achieve analgesic fentanyl concentration (0.5-2 ng/ml) in maternal plasma. A total of 20 Aland landrace ewes at 118-127 gestational days were used. In the first protocol, 1 week before surgery, 10 animals received 2 μg/kg fentanyl intravenous bolus, and on the operation day, transdermal fentanyl patches at nominal dose rate of 2 μg/kg/hr were applied to antebrachium, and ewes were then given a 2 μg/kg intravenous bolus followed by an intra-operative 2.5 μg/kg/hr infusion. In the second protocol, 10 animals received fentanyl only as transdermal patches on the operation day and oxycodone for rescue analgesia. The data were analysed with population pharmacokinetic modelling. Intra- and post-operative fentanyl concentrations were similar and slightly lower than the a priori predictions, and elimination and distribution clearances appeared slower during than before or after the surgery. Transdermal patches provided sustained fentanyl absorption for up to 5 days, but the absorption rate was slower than the nominal dose rate and showed a high interindividual variability. Further research is warranted to evaluate the clinical relevance of the observations made in sheep.

    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

    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

    The objective of this study was to evaluate the distribution of silver nanoparticles (NPs) in pregnant mice and their developing embryos. Silver NPs (average diameter 50 nm) were intravenously injected into pregnant CD-1 mice on gestation days (GDs) 7, 8, and 9 at dose levels of 0, 35, or 66 μg Ag/mouse. Mice were euthanised on GD10, and tissue samples were collected and analysed for silver content. Compared with control animals injected with citrate buffer vehicle, silver content was significantly increased (p < 0.05) in nearly all tissues from silver NP-treated mice. Silver accumulation was significantly higher in liver, spleen, lung, tail (injection site), visceral yolk sac, and endometrium compared with other organs from silver NP-treated mice. Furthermore, silver NPs were identified in vesicles in endodermal cells of the visceral yolk sac. In summary, the results demonstrated that silver NPs distributed to most maternal organs, extra-embryonic tissues, and embryos, but did not accumulate significantly in embryos. PMID:22023110

    Opioid misuse during pregnancy is associated with negative outcomes for both mother and fetus due not only to the physiological effects of the drug but also to the associated social, medical and mental health problems that accompany illicit drug use. An interdisciplinary approach to the treatment of opioid use disorder during pregnancy is most effective. Ideally, obstetric and substance use treatment are co-located and ancillary support services are readily available. Medication-assisted treatment with methadone or buprenorphine is intrinsic to evidence-based care for the opioid-using pregnant woman. Women who are not stabilized on an opioid maintenance medication experience high rates of relapse and worse outcomes. Methadone has been the mainstay of maintenance treatment for nearly 50 years, but recent research has found that both methadone and buprenorphine maintenance treatments significantly improve maternal, fetal and neonatal outcomes. Although methadone remains the current standard of care, the field is beginning to move towards buprenorphine maintenance as a first-line treatment for pregnant women with opioid use disorder, because of its greater availability and evidence of better neonatal outcomes than methadone. However, there is some evidence that treatment dropout may be greater with buprenorphine relative to methadone. PMID:26315948

    Background There are few studies focusing on women's experiences of early pregnancy. Medical and psychological approaches have dominated the research. Taking women's experiences seriously during early pregnancy may prevent future suffering during childbirth. Aim To describe and understand women's first time experiences of early pregnancy. Method Qualitative study using a phenomenological hermeneutic approach. Data were collected via tape-recorded interviews in two antenatal care units in Sweden. Twelve first time pregnant women in week 10–14, aged between 17 and 37 years participated. Results To be in early pregnancy means for the women a life opening both in terms of life affirming and suffering. The central themes are: living in the present and thinking ahead, being in a change of new perspectives and values and being in change to becoming a mother. Conclusions The results have implications for the midwife's encounter with the women during pregnancy. Questions of more existential nature, instead of only focusing the physical aspects of the pregnancy, may lead to an improvement in health condition and a positive experience for the pregnant woman.

    Pregnancy adds many sources of concerns to women's daily life worries. Excessive worry can affect maternal physiological and psychological state that influences the pregnancy outcomes. The aim of this study was to validate the Cambridge Worry Scale (CWS) in a sample of Iranian pregnant women. After translation of the CWS, ten experts evaluated the items and added six items to the 17-item scale. In a descriptive cross-sectional study, 405 of pregnant women booked for prenatal care completed the Farsi CWS. We split the sample randomly. Exploratory factor analysis (EFA) was conducted on the first half of the sample to disclose the factorial structure of the 23-item scale. The results of the EFA on the Farsi CWS indicated four factors altogether explained 51.5% of variances. Confirmatory factor analysis (CFA) was done on the second half of the sample. The results of the CFA showed that the model fit our data (chi-square/df = 2.02, RMSEA = 0.071, SRMR = 0.071, CFI = 0.95, and NNFI = 0.94). Cronbach's alpha coefficient for the Farsi CWS was 0.883. The Farsi CWS is a reliable and valid instrument for understanding common pregnancy worries in the third trimester of pregnancy in Iranian women.

    A pregnant, non-Japanese-speaking Peruvian, and, thus, with communication difficulty, suffered hyperemesis gravidarum and had respiratory arrest, requiring cardiopulmonary resuscitation. The obese pregnant woman (prepregnancy weight: 107 kg) had vomited and lost 15 kg in bodyweight over appropriately 2 weeks prior to the arrest but had not complained due to communication difficulty, which, together with her obesity, prevented a Japanese obstetrician from noticing her severe condition. 1,000 mL of low potassium fluid plus thiamine was administered. She became unable to stand, suggesting lower-extremity-proximal-muscle weakness, and then respiratory arrest occurred. Hypopotassemia (2.3 mEq/L), pulseless electrical activity, and muscle weakness suggested the presence of severe potassium deficiency, which may have caused respiratory muscle paralysis, leading to the respiratory arrest. Hypercapnea was severer than expected for compensatory hypoventilation, indicating the presence of concomitant severe hypoventilation, which may also have contributed to respiratory arrest. She recovered with electrolyte and volume replacement. Respiratory arrest can occur with hyperemesis gravidarum, and obesity and communication difficulties can prevent the early detection of severe conditions. PMID:26693367

    Introduction: Down syndrome is one of the most prevalent genetic diseases. Screening methods for this syndrome are easy and safe and are recommended to all pregnant women particularly mothers over 35 years of age. This study aimed to review the status of Down syndrome screening and related factors in Iranian pregnant women. Methods: This descriptive analytical study was carried out in 2011. It included 400 women who were randomly selected from those referring to Alzahra Hospital (Tabriz, Iran) during their third trimester of pregnancy. Data was collected through a question-naire whose reliability and validity have been approved. The data was analyzed by chi-square test in SPSS13. Results: The results showed that while 28 and 26 women imple-mented screening tests during the first and second trimesters, respectively, only 5 sub-jects benefited from both (integrated test). Chi-square test showed significant correla-tions between the implementation of screening methods and age, education level, in-come, and the location of prenatal care (p < 0.05). Conclusion: The findings of the present study showed women to poorly implement Down syndrome screening methods. Therefore, the necessity of providing appropriate educational programs for health staff and mothers seems undeniable. Moreover, paying attention to the related factors such as income, educational level, and adequate training of mothers during pregnancy is essential. PMID:25276689

    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.

    Purpose. To show whether pregnancy affects the measurements of pupillary diameter and wavefront (WF) aberrations. Methods. This was a case-control study including 34 healthy pregnant women in the third trimester and age-matched 34 nonpregnant women. Only women who had no ocular abnormalities and no refractive error were included. We measured photopic and mesopic pupil diameter and WF aberrations at the third trimester and at the second postpartum month. Measurements of the right eyes were used in this study. The differences between groups were analysed by paired t-test and t-test. Results. Pregnant women's mean photopic pupil size in the third trimester was significantly higher than in postpartum period and in control group (3.74 ± 0.77, 3.45 ± 0.53, and 3.49 ± 0.15 mm, p < 0.05, resp.). Mesopic pupil size in the third trimester was also higher than in postpartum period and in control group (6.77 ± 0.52, 6.42 ± 0.55, and 6.38 ± 0.21 mm, p < 0.05, resp.). RMS-3 and RMS-5 values were higher in pregnancy but these differences were not statistically significant. Conclusion. Pregnancy increased photopic and mesopic pupil size significantly but did not increase wavefront aberrations notably. Increased pupil size may be due to increased sympathetic activity during pregnancy. And this activity can be noninvasively determined by measuring pupil size. PMID:26998383

    Pregnancy toxemia was induced in nine pregnant goat does with twins by the stress of fasting with access to water in late pregnancy to investigate the effect of pregnancy toxemia on immunoglobulins (IgA, IgM, and IgG), cortisol, insulin, thyroid, and growth hormones and their correlations with the plasma levels of glucose and β-Hydroxybutyrate. Plasma samples were collected at 0, 12, 24, 36, 48, and 72 hours after induction of pregnancy toxemia. The result revealed that experimental animals developed neurological findings with convulsions and acetone odor from the mouth with recumbency after 72 hours. Laboratory findings showed a significant increase in β-Hydroxybutyrate, cortisol, and insulin while there were significant decreases in glucose, thyroid, and immunoglobulins (IgA, IgM, and IgG). Plasma glucose concentrations had significant negative correlations with β-hydroxybutyrate, cortisol, and insulin while the correlations were significantly positive with immunoglobulins and thyroid hormone. Plasma β-hydroxybutyrate concentration was significantly positively correlated with cortisol and negatively correlated with immunoglobulins, insulin, and thyroid hormone. From this study we can conclude that pregnancy toxemia might affect humoral immune responses as well as insulin, cortisol, and thyroid hormones. Moreover, insulin might have a compensatory role to increase suppressive effect on ketogenesis in experimentally pregnant toxemic goats. PMID:20613964

    Bacteroides fragilis is an anaerobic bacterial species that is involved in gynecological infections and pathology. The incidence of vaginal carriage is largely unknown, and in order to study this, 120 pregnant women attending a general hospital for delivery were examined. Cultures were positive for eight of these women (6.6%). Interestingly, potential clonal relatedness could be demonstrated among several of the nonenterotoxigenic B. fragilis strains. Among the strains, only one produced metalloprotease enterotoxin. The presence of the gene for the metalloprotease, giving rise to the pathogenic effect on cultured eukaryotic HT29/C1 cells, was confirmed by a newly designed specific PCR assay. The enterotoxigenic B. fragilis (ETBF) strain was analyzed with the help of arbitrarily primed PCR (AP-PCR) and PCR-mediated ribotyping. The ETBF strain was shown to be genetically different compared to several other strains obtained from diverse sources. Our data indicate a relatively high vaginal B. fragilis carriage rate among pregnant women in Warsaw, Poland. Although neither ETBF nor B. fragilis colonization presented a clinical problem, the possible genetic relatedness among the colonizing B. fragilis strains indicates the need for additional research in the field of ETBF transmission and molecular epidemiology.

    Promising clinical results suggest that umbilical cord blood (UCB) collected after delivery of a child may have many advantages over bone marrow for transplantation. As there are an increasing number of options regarding the collection of UCB, including private and public banking, more pregnant women are likely to be asked to make decisions about UCB collection. We conducted three focus groups with pregnant women to learn about their perspectives on this emerging technology. All the women in these focus groups indicated that they would choose to have UCB collected. Reasons leading to this choice were that the UCB would otherwise be discarded and altruism. Participants indicated that possible reasons to decide not to have UCB collected include concerns about the safety of the mother and neonate, beliefs about the placenta, threats against confidentiality, rejection of UCB, and the influence of fathers. While feeling confident in making an anticipatory decision about UCB collection, women expressed a clear desire to learn much more about the collection, storage (including distinctions between public and private banking), and use of UCB. In addition, they believed that recruitment for UCB collection should occur after sufficient education about UCB and certainly not after delivery and collection. These data will be useful in guiding efforts to help women make decisions about having UCB collected and in developing an appropriate recruitment and informed consent process for donating UCB to a public bank.

    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. PMID:26101526

    Freedom of information, access to and ownership of medical records are current and controversial issues in Australia. Relating to pregnancy and birth the debate provokes emotional responses and raises important questions about access to information, decision-making, responsibility, power and control. The aim of this qualitative study was to explore the impact on pregnant women of carrying their medical records throughout pregnancy Twenty-one women participated in face-to-face individual interviews, which were coded for thematic analysis. The study found the reaction of women toward carrying their own records to be overwhelmingly positive. Maternal record holding had the potential to improve the level of communication between the health care worker and the pregnant woman and provided a greater sense of sharing and communication within the family The study also established that maternal record holding was of benefit to the woman's partner who was better informed and more involved in the pregnancy All but one of the women who participated favoured carrying their records in subsequent pregnancies. A concern about the potential for losing or misplacing records was not seen in this study, as no women lost their records. A sense of ownership would argue against this possible drawback.

  5. Studies say doctors are lax in assisting pregnant women.

    1995-06-30

    In an International Clinical Conference Call, a national telephone hookup that enables people in the field to pose questions to experts, speakers agreed that doctors are not moving quickly enough to deal with the privacy, counseling and treatment issues associated with pregnant women who are HIV-positive. In two recent studies, less than half of the doctors surveyed were aware that prescribing the antiviral drug AZT during pregnancy, labor, and childbirth, could reduce by two-thirds the risk of HIV transmission to the infant. The results are alarming because research on the benefits of AZT therapy in pregnancy has been widely disseminated since August. In February, the Centers for Disease Control and Prevention (CDC) recommended that physicians counsel all pregnant women about the risk of HIV infection. Most physicians, however, seem to regard HIV counseling as too complicated or too touchy a subject to address. Another issue discussed during the June 8 telephone conference was the costs of treating a woman and infant with AZT, approximately $1,000, compared to the cost of treating HIV infection in an infant, $38,000 per year.

    This case report concerns a 25-year-old patient with 6-7 bloody stools/d, abdominal pain, tachycardia, and weight loss occurring during the third trimester of pregnancy. Severe ulcerative colitis complicated by toxic megacolon and gravidic sepsis was diagnosed by clinical evaluation, colonoscopy, and rectal biopsy that were performed safely without risk for the mother or baby. The patient underwent a cesarean section at 28+6 wk gestation. The baby was transferred to the neonatal intensive care unit of our hospital and survived without complications. Fulminant colitis was managed conservatively by combined colonoscopic decompression and medical treatment. Although current European guidelines describe toxic megacolon as an indication for emergency surgery for both pregnant and non-pregnant women, thanks to careful monitoring, endoscopic decompression, and intensive medical therapy with nutritional support, we prevented the woman from having to undergo emergency pancolectomy. Our report seems to suggest that conservative management may be a helpful tool in preventing pancolectomy if the patient's condition improves quickly. Otherwise, surgery is mandatory. PMID:26019473

    A prospective and descriptive study was done in pregnant women diagnosed with herpes zoster, to know the demographic characteristics and clinical manifestations as well as maternal and/or neonatal complications to cause by this viral infection during pregnancy. The study included all pregnant women diagnosed with herpes zoster at the Department of Infectious Diseases of the Instituto Nacional de Perinatologia México, between 1994 and 2002. A total of 17 women were included in the study. All were given clinical and ultrasound follow-up to discard any maternal or fetal complications also at the moment of birth. A review in the newborn was made to establish the demographic, anthropometric and clinical characteristics; also the data collected included mother's age, gestational age at the moment of diagnosis with herpes zoster, anatomical lesion site, treatments administered, ultrasound characteristics, newborn's gestational age, weight, height, Apgar at birth and type of delivery. The most frequent site (58.8%) for herpes zoster lesions on the mother was the intercostal area, followed by the scapular region, the lumbar region and the limbs. None of the patients experienced complications during pregnancy, including post-herpetic pain. Sixteen of the newborns had no complications and one was a stillborn due to 60% of placental separation. These findings suggest a benign evolution of herpes zoster during pregnancy, supporting similar findings in the literature. No complications during pregnancy are suggested, and no phenotypical alterations occurred in the child at the moment of birth.

    We share here our experience of recruiting pregnant women into an exercise intervention study. Recruitment challenges were anticipated owing to the study design, which required four hospital visits for cardiovascular assessment, a long-term (nine-month) commitment, and adherence to a 20-week exercise programme. Fifty-three women were assigned to one of three groups (no-exercise, land exercise or water exercise) using a 2 × 2 × 2 flexible randomisation design. Seven hundred forty-four women were screened at an antenatal clinic, of whom 501 were eligible to participate in the study. One hundred forty-five women were subsequently approached: 46 (32%) of whom agreed to participate, 42 (29%) were interested but then declined and 57 (39%) declined outright. Our study design helped recruit pregnant women as it allowed them some choice of group membership. We also noted that the participant-researcher relationship is important in reducing attrition. Our experience provides indications of likely recruitment and attrition rates for future randomised controlled trials of this type.

    Postpartum depression (PPD) is associated with debilitating effects on mothers and their infants. A previous history of depression is considered the strongest risk factor for PPD. Depressed individuals recall more negative than positive content and higher levels of stress hormones released during encoding are associated with enhanced recall of emotional stimuli. This study examined the impact of a previous history of major depressive disorder (MDD) and pregnancy on emotional memory. Seventy-seven participants completed the study [44 pregnant women in the second trimester of pregnancy with and without a lifetime history of MDD and 33 non-pregnant women with and without a lifetime history of MDD]. All completed an encoding task and provided salivary cortisol (sCORT) and alpha-amylase (sAA) samples. Participants returned one week later for a surprise incidental recognition memory task. Women with a history of MDD had worse recognition than women without a history of MDD for negative, but not positive images; this effect was independent of sCORT and sAA levels. Pregnancy did not affect emotional memory. Considering that several previous studies found enhanced memory bias for negative content during depressive states, our results suggest that clinical remission may be associated with an opposite cognitive processing of negative emotional content.

    Cocaine abuse is associated with premature labor. Although cocaine is known to competitively inhibit beta-adrenergic receptor binding, cocaine's effect on receptor downregulation is uncertain. This study was designed to determine the in vitro effect of cocaine on downregulation of beta-adrenergic receptors in pregnant myometrium. Pregnant sheep myometrium was incubated with either cocaine, isoproterenol, or a cocaine metabolite, benzoylecgonine. Membrane fractions were assayed for beta-adrenergic receptors using (125I)-cyanopindolol and the beta 2-adrenergic antagonist ICI 118,551. We found that cocaine (10(-6) to 10(-4) mol/L), but not benzoylecgonine, downregulated both beta 1- and beta 2-adrenergic receptors, but did not further augment receptor downregulation by isoproterenol. The 46% decrease in beta-adrenergic receptors seen after exposure to cocaine was similar to the 53% decrease seen after isoproterenol. We hypothesize downregulation of beta-adrenergic receptors by cocaine may play a role in the association of cocaine abuse with premature labor.

    OBJECTIVES: Hepatitis B virus (HBV) is a major blood-borne and sexually transmitted infectious agent that is a significant global public health issue. The aim of this study was to determine the seroprevalence and risk factors of HBV among pregnant women attending the antenatal clinic of the Hawassa University referral hospital in Ethiopia. METHODS: A cross-sectional study was conducted from April to May, 2015. A total of 269 consecutive pregnant women attending antenatal consultations were enrolled. Sociodemographic information and data regarding possible risk factors were collected using a structured questionnaire. Hepatitis B surface antigen (HBsAg) screening was performed using an enzyme-linked immunosorbent assay, and the data were analyzed. RESULTS: The overall seroprevalence of HBsAg among the 269 participants enrolled in the study was 7.8% (n=21). The prevalence of human immunodeficiency virus (HIV) infection was 5.2% (n=14), of whom two participants (14.2%) were also positive for HBsAg. Study participants with no formal education (odds ratio [OR], 3.68; 95% confidence interval [CI], 1.27 to 10.68; p<0.05) were more likely to be infected with HBV than those who had completed at least secondary school. Although HBsAg was detected more often in pregnant women who had multiple exposure factors (8.8%, n=13) than in pregnant women who had not experienced possible risk factors (4%, n=1), this difference was not statistically significant (OR, 2.33; 95%CI, 0.29 to 18.63). CONCLUSIONS: A high prevalence of HBV infection was detected in the study population. Neither the type of risk factors nor exposure to multiple risk factors was significantly associated with HBV infection. Hence, screening pregnant women regardless of risk factors and improving awareness of the transmission routes of HBV within this group may reduce the risk of HBV infections. PMID:27336446

This study was designed to determine the role of endogenous TNF-α in mediating changes in arterial pressure and endothelin-1 (ET-1) in RUPP rats. To achieve this goal we examined the effect of RUPP in the presence and absence of a TNF-α–soluble receptor, etanerecept (0.4 mg/kg). Mean arterial pressure increased from 102±1 mm Hg in normal pregnant (NP) rats to 134±3 mmHg (P<0.05) in RUPP rats. Serum TNF-α increased to 40±7.6 pg/mL in RUPP rats (n=24) versus 14.8±3.3 pg/mL (n=16; P<0.05) in NP rats. Administration of etanerecept decreased TNF-α in RUPP rats (n=20) to 17.2±3 pg/mL and mean arterial pressure to 118±2 mmHg (P<0.05). Tissue ET-1 decreased in etanerecept-treated RUPP rats compared with control RUPP rats. The direct effect of TNF-α blockade on endothelial activation in response to placental ischemia was examined in human umbilical vein endothelial cells. ET-1 secreted from human umbilical vein endothelial cells treated with RUPP serum was 59.2±16 pg/mg and decreased when etanerecept was added to the medium with RUPP serum (7.60±0.77 pg/mg), as well as in response to serum from etanerecept-treated RUPP rats (7.30±0.55 pg/mg; P<0.001). ET-1 secreted from human umbilical vein endothelial cells was 15.6±2 pg/mg when treated with NP serum. These data support the hypothesis that endogenous TNF-α is an important stimulus for ET-1 in response to placental ischemia and is important in mediating endothelial cell activation and hypertension during pregnancy.

    There is a heavy disease burden due to seasonal influenza in pregnant women, their fetuses, and their newborns. The main aim of this study was to review and analyze current evidence on safety, immunogenicity, and clinical benefits of the inactivated influenza vaccine (IIV) in pregnant women. Current evidence shows that in pregnant women, the seasonal and pandemic IIVs are safe and well tolerated. After vaccination, pregnant women have protective concentrations of anti-influenza antibodies, conferring immunogenicity in newborns. The best evidence, to date, suggests that influenza vaccination confers clinical benefits in both pregnant women and their newborns. Vaccination with either the seasonal or pandemic vaccine has been shown to be cost-effective in pregnancy. There are scarce data from randomized clinical trials; fortunately, new phase 3 clinical trials are under way. In the Northern and Southern Hemispheres, data suggest that the greatest clinical benefit for infants occurs if the IIV is administered within the first weeks of availability of the vaccine, at the beginning of the influenza season, regardless of the pregnancy trimester. The optimal timing to vaccinate pregnant women who live in tropical regions is unclear. Based on evaluation of the evidence, the Global Influenza Initiative (GII) recommends that to prevent seasonal influenza morbidity and mortality in infants and their mothers, all pregnant women, regardless of trimester, should be vaccinated with the IIV. For countries where vaccination against influenza is starting or expanding, the GII recommends that pregnant women have the highest priority. PMID:26256293

    1989-01-01

    The 1990 health objectives for the nation state that pregnant women should be only half as likely to smoke as nonpregnant women. To assess progress toward meeting this objective, we used cross-sectional data from the 26 states in the Behavioral Risk Factor Surveillance System in 1985 and 1986. We compared the prevalence of self-reported smoking among pregnant (N = 836) and nonpregnant (N = 18,025) women aged 18 to 45 years. Overall, pregnant women were 70% as likely to be current smokers as nonpregnant women (prevalence ratio, 0.7; 95% confidence interval, 0.6 to 0.8), while blacks showed the largest pregnancy-associated reduction in the prevalence of smoking (prevalence ratio, 0.5; 95% confidence interval, 0.3 to 0.9). Most of the difference in smoking prevalence occurred not because pregnant women were less likely to have ever smoked, but because pregnant women were more likely to have quit smoking than nonpregnant women. However, unmarried pregnant white women were 40% more likely to smoke than their nonpregnant counterparts (prevalence ratio, 1.4; 95% confidence interval, 1.1 to 1.7). We conclude from this analysis that the 1990 health objective for smoking among pregnant women is unlikely to be achieved. Clinicians providing care to pregnant women need to pay increased attention to smoking cessation.

    2005-02-01

    Antiretroviral therapy (ART) initiated on a prenatal basis in HIV-infected pregnant women is a highly effective method for preventing mother-to-child HIV transmission. We developed a decision analytic model to project the clinical and economic outcomes of alternative HIV screening strategies (voluntary prenatal screening [VPS], routine prenatal screening [RPS], and mandatory newborn screening [MNS]) for a high-risk population of incarcerated pregnant women. Data for the decision model came from the HIV voluntary counseling and testing program at Connecticut's sole correctional facility for women and a comprehensive anonymously linked serosurvey of all inmates who entered the facility during the 2-year period beginning in October 1994. Based on serosurvey results, in the absence of any HIV screening program, 2.5 cases of pediatric HIV infection would be expected per 1000 pregnancies. Multiplied by the discounted lifetime cost per case of $247,000, this translates to a cost of $624 per testing-eligible prison entrant. Entrants were considered eligible if they were pregnant and their HIV status was unknown. MNS would save money, cost $364 per eligible entrant, and simultaneously reduce the rate of infections to 1.1 per 1000 pregnancies. Doing both MNS and RPS is most effective in reducing the rate of new infections (down to 0.2 per 1000 pregnancies). It would, however, increase costs to $430 per eligible entrant. This would result in an incremental cost of $73,603 per additional pediatric HIV case averted when compared with MNS alone. If mandatory newborn testing was not considered a feasible option, RPS would dominate VPS and would be cost-saving compared with no screening. RPS compares favorably with alternative uses of HIV prevention and treatment resources. In correctional facilities where voluntary newborn screening is already in place, our findings show that there remains a small marginal benefit to be realized from switching to RPS. In settings where HIV

    AimThe aims of this study were to investigate the relationship between pregnant women's personal exposures to NOx, NO2, PM2.5 concentration and absorbance as a marker for black carbon and their indoor and outdoor concentration levels at their residence, and also to identify predictors of personal exposure and indoor levels using questionnaire and time activity data. MethodWe recruited 54 pregnant women in Barcelona who carried a personal PM2.5 sampler for two days and NOx/NO2 passive badges for one week, while indoor and outdoor PM2.5 and NOx/NO2 levels at their residence were simultaneously measured. Time activity and house characteristics were recorded. Gravimetry determinations for PM2.5 concentration and absorbance measurements were carried out on the PM2.5 filter samples. ResultsLevels of personal exposure to NOx, PM2.5 and absorbance were slightly higher than indoor and outdoor levels (geometric mean of personal NOx = 61.9 vs indoor NOx = 60.6 μg m-3), while for NO2 the indoor levels were slightly higher than the personal ones. Generally, there was a high statistically significant correlation between personal exposure and indoor levels (Spearman's r between 0.78 and 0.84). Women spent more than 60% of their time indoors at home. Ventilation of the house by opening the windows, the time spent cooking and indicators for traffic intensity were re-occurring statistically significant determinants of the personal and indoor pollutants levels with models for NOx explaining the 55% and 60% of the variability respectively, and models for NO2 explaining the 39% and 16% of the variability respectively. Models for PM2.5 and absorbance explained the least of the variability. ConclusionOur findings improve the current understanding of the characterization and inter-associations between personal, indoor and outdoor pollution levels among pregnant women. Variability in personal and indoor NOx and to a lesser extent NO2 levels could be explained well, but not the variability

    2009-01-01

    Background Thyroid function changes during pregnancy and maternal thyroid dysfunction have been associated with adverse outcomes. Our aim was to evaluate thyroid hormones levels in pregnant women resident in Aragon, Spain. Findings Samples for 1198 pregnant women with no apparent thyroid disorders were analyzed, using paramagnetic microparticle and chemiluminescent detection technologies, in order to determine levels of thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), thyroid peroxidase antibodies (TPO-Ab), and thyroglobulin antibodies (Tg-Ab). Of the women in our sample, 85.22% had normal values for TPO-Ab and Tg-Ab and 14.77% had results revealing the presence of autoimmune diseases of the thyroid. The thyroid hormone reference values obtained according to gestational age (in brackets) were as follows: for free T3, values were 3.38 ± 0.52 pg/mL (<11 weeks), 3.45 ± 0.54 pg/mL (11-20 weeks), 3.32 ± 0.43 pg/mL (21-30 weeks), 3.21 ± 0.53 pg/mL (31-36 weeks), and 3.23 ± 0.41 pg/mL (>36 weeks); for free T4, values were 1.10 ± 0.14 ng/dL (<10 weeks), 1.04 ± 0.14 ng/dL (11-20 weeks), 0.93 ± 0.12 ng/dL (21-30 weeks), 0.90 ± 0.13 ng/dL (31-36 weeks), and 0.80 ± 0.21 ng/dL (>36 weeks); and for TSH, values were (μIU/mL): 1.12 ± 0.69 (<10 weeks), 1.05 ± 0.67 (11-20 weeks), 1.19 ± 0.60 (21-30 weeks), 1.38 ± 0.76 (31-36 weeks), and 1.46 ± 0.72 (>36 weeks). Conclusion Pregnant women with normal antibody values according to gestational age had values for FT4 and TSH, but not for FT3, that differed to a statistically significant degree. The values we describe can be used as reference values for the Aragon region of Spain. PMID:19939287

    Abstract Background: Pregnant women with major depressive disorder (MDD) report that psychotherapy is a more acceptable treatment than pharmacotherapy. However, although results of several studies suggest that psychotherapy is an effective treatment for pregnant women, logistical barriers—including cost and traveling for weekly visits—can limit real-world utility. We hypothesized that computer-assisted cognitive behavior therapy (CCBT) would be both acceptable and would significantly decrease depressive symptoms in pregnant women with MDD. Methods: As a preliminary test of this hypothesis, we treated 10 pregnant women with MDD using a standardized CCBT protocol. Results: The pilot results were very promising, with 80% of participants showing treatment response and 60% showing remission after only eight sessions of CCBT. Conclusion: A larger, randomized controlled trial of CCBT in pregnant women with MDD is warranted. PMID:25268672

    The authors purpose was to determine whether renal autoregulatory capability is retained in pregnancy despite the marked renal vasodilation that occurs at this time. Renal blood flow and glomerular filtration rate (GFR) were measured in anesthetized pregnant (22-27 days gestation) and nonpregnant rabbits during step reductions in renal perfusion pressure from control (100 +/- 3 mmHg) to 50 mmHg. Control renal blood flow and GFR were significantly higher in pregnant animals. Filtration fraction was also significantly elevated in pregnant animals. During step reductions in renal perfusion pressure, renal blood flow was well autoregulated down to approx.70 mmHg in both nonpregnant and pregnant animals. Likewise, GFR was also well autoregulated, falling by 10 +/- 2 and 8 +/- 3% in nonpregnant and pregnant animals, respectively, when perfusion pressure was reduced from 90 to 70 mmHg. These results suggest that renal autoregulation is preserved in pregnancy despite the fact that the renal circulation is already markedly vasodilated.

    Objective Long-chain omega 3 fatty acids, eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3) exert potent anti-inflammatory properties in humans. This study characterized the effects of omega-3 ω-3 fatty acids supplements (ω-3 FA) on the inflammatory status in the placenta and adipose tissue of overweight/obese pregnant women. Study Design A randomized, double-masked controlled trial was conducted in overweight/obese pregnant women that were randomly assigned to receive DHA plus EPA (2g/day) or the equivalent of a placebo twice a day from week 10–16 to term. Inflammatory pathways were characterized in: 1) adipose tissue and placenta of treated vs. untreated women; and 2) adipose and trophoblast cells cultured with long chain FAs. Results The sum of plasma DHA and EPA increased by 5.8 fold and ω-3 FA/ ω-6 FA ratio was 1.5 in treated vs. untreated women (p< 0.005). Plasma CRP concentrations were reduced (p<0.001). The adipose tissue and placenta of treated women exhibited a significant decrease in TLR4 adipose and placental expression as well as IL6, IL8, and TNFα In vitro, EPA and DHA suppressed the activation of TLR4, IL6, IL8 induced by palmitate in culture of adipose and trophoblast cells. Conclusion Supplementation of overweight/obese pregnant women with dietary ω-3 FAs for >25 weeks reduced inflammation in maternal adipose and the placental tissue. TLR4 appears as a central target of the anti-inflammatory effects at the cellular level. Trial Registration ClinicalTrials.gov NCT00957476 PMID:26340264

    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

    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

    Radiographic imaging of the pregnant patient represents a diagnostic and management dilemma for the orthopaedic surgeon. Imaging is often necessary in the setting of trauma; however, in utero radiation exposure can result in deleterious developmental effects in the embryo and fetus. The likelihood of a negative effect is proportional to the radiation dose and the gestational age of the embryo or fetus at the time of exposure. Ionizing radiation doses >100 mGy in the first trimester of pregnancy may lead to spontaneous abortion, malformation, and mental retardation. Whereas plain radiographs of the extremities and cervical spine expose the fetus to minimal doses of radiation of <10 mGy, other commonly performed orthopaedic diagnostic studies, such as CT of the pelvis, emit significantly higher exposure doses of approximately 35 mGy. Non-emitting modalities, such as ultrasonography and MRI, are alternatives for evaluation in the clinical setting. PMID:26116850

    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.

  18. The prevalence and incidence of Toxoplasma antibodies in pregnant women.

    A group of 213 pregnant Jewish women of Israeli and North-African/Asian origin in the Upper Gallilee in Israel were tested for Toxoplasma antibody, first at 4-12 weeks gestation and again 5-6 months later. Immunofluorescent antibody, Sabin-Feldman tests, and specific IgM estimation were used. The prevalence rates for seropositive women were lower in both groups (total 21%) than the rate found in a 1973 study in Israel. The incidence rate for infection acquired in pregnancy was 1.4%. There were no cases of congenital toxoplasmosis, as far as is known up to 3 years of age. More information on the prevalence and incidence of seropositivity, and on congenital toxoplasmosis, is required before a policy decision can be taken as to whether an antenatal screening program for toxoplasmosis should be instituted in Israel.

  19. Management of Pregnant Patients Who Refuse Medically Indicated Cesarean Delivery

    The doctrine of informed refusal may become difficult to adhere to in obstetric practice, especially in situations in which the fetus’s life is at risk. One rare yet potentially problematic situation of informed refusal is the case of a pregnant woman who refuses to undergo a medically indicated cesarean delivery that would ensure the well-being of her fetus. Although some would argue that patient autonomy takes precedence and the woman’s informed refusal should be respected, others would argue that beneficence, justice, and doing no harm to the viable fetus should ethically overrule the refusal of a surgery. This article explores the profound conflict between maternal autonomy and the rights of the fetus, provides a framework to address when the two diverge, and poses suggestions for how providers can better navigate this dilemma.

    We realized a double-blind randomized study in 26 pregnant with clinical symptoms of lower limbs venous insufficiency. Both groups were similar and received either (n = 12) troxerutine (4 g/day) or placebo (n = 14), during 30 days. Evaluation at J0 and J30 was both clinical and rheological by mean of Myrenne aggregometer. After blood shear rate of 600 s-1, two parameters were determined: M after roughly stopping shear rate, M1 after diminishing to shear rate of 3 s-1. Results exhibited steady values in patients receiving troxerutine while a significant increasing values in patients receiving placebo for the two parameters M and M1. That result in erythrocyte antiaggregating action of troxerutine, hence lowering viscosity action, in venous insufficiency during pregnancy.
