    Introduction. Aplastic anemia is a rare disease caused by destruction of pluripotent stem cells in bone marrow. During pregnancy it could be life-threatening for both mother and child. The only causal therapy for aplastic anemia is bone marrow transplantation, which is contraindicated during pregnancy because of potential embryo toxicity. Treatment options are erythrocytes and platelet transfusions and immunosuppressive therapy. There is, however, no agreement about the optimal supportive care and treatment regime for this disorder during pregnancy. Case Presentation. A 26-year-old nulliparous Asian woman with an uneventful medical history was admitted to the hospital at 14 weeks' gestation because of excessive vomiting. Routine laboratory tests showed pancytopenia (Hb 3.5 mmol/L, leukocytes 3.5 *109/L, platelets 45 *109L). A bone marrow biopsy confirmed aplastic anemia. Methylprednisolon, cyclosporine A, packed cells and platelet transfusions were initiated. At 33 weeks she developed neutropenia (0.1 *109/L) for which oral colistin and tobramycin were given prophylactically. At 35 weeks labor was induced, during which she developed a fever of 38.2°C. She gave birth spontaneously to a healthy son weighing 2415 grams, who had no signs of pancytopenia. After delivery the blood count of the patient did not recover and did not respond to medication. Eighteen weeks after delivery she died of sepsis complicated by cerebral bleeding and infarction due to severe thrombocytopenia and neutropenia, despite optimal supportive treatment. Conclusion: This potential life-threatening disease has a relatively good prognosis for both mother and child after optimal treatment. Transfusion during pregnancy is the first choice treatment with recommended hemoglobin levels of 5.5 mmol/L and platelet counts of20 *109/L. Cyclosporine A seems a reasonable alternative therapy with a reported success rate in non-pregnant patients of 70% when combined with antithymocyte globuline. Our patient died 18 weeks postpartum from cerebral bleeding and infarction due to severe thrombocytopenia despite intensive supportive treatment, methylprednisolon and cyclosporine A

    __Doel:__ Het verband tussen woonwijk, etniciteit en ongunstige perinatale uitkomsten analyseren bij zwangeren in de 4 grootste steden (Amsterdam, Rotterdam, Den Haag en Utrecht; G4) en in de rest van Nederland. __Opzet:__ Descriptief, retrospectief. __Methode:__ De perinatale uitkomst van 877.816 eenlingzwangerschappen in Nederland in de periode 2002-2006, vastgelegd in de Perinatale Registratie Nederland, werd geanalyseerd op etniciteit van de zwangere (westers of niet-westers) en op woonwijk (achterstandswijk (‘prachtwijk’) of niet) in de G4-steden en daarbuiten. Een ongunstige perinatale uitkomst was gedefinieerd als perinatale sterfte, congenitale afwijkingen, dysmaturiteit, vroeggeboorte, een apgar-score na 5 minuten < 7 en/of opname op een neonatale intensivecareunit. __Resultaten:__ Het perinatale sterftecijfer was in de G4-steden hoger dan in de rest van Nederland (11,1 versus 9,3‰; p < 0,001; 95%-BI van het verschil: 1,2-2,4‰). Hetzelfde gold voor het totaal van ongunstige perinatale uitkomsten (154,9 versus 138,9‰). In de G4-steden was de perinatale sterfte in de groep niet-westerse vrouwen hoger dan in de groep westerse vrouwen (13,2 versus 9,5‰). Het wonen in een prachtwijk gaat gepaard met een hogere perinatale sterfte dan in een niet-prachtwijk (13,5 versus 9,3‰). De relatieve risico’s van het wonen in een prachtwijk zijn groter bij westerse dan bij niet-westerse vrouwen. __Conclusie:__ Vrouwen in de G4-steden hebben een sterk verhoogde kans op een ongunstige perinatale uitkomst. Wonen in een prachtwijk vormt een nog groter risico, vooral voor westerse zwangeren. Deze bevindingen zijn van belang voor het vaststellen van nieuwe strategieën ter

    Learning from failure

    We study decentralized learning in organizations. Decentralization is captured through a symmetry constraint on agents’ strategies. Among such attainable strategies, we solve for optimal and equilibrium strategies. We model the organization as a repeated game with imperfectly observable actions. A fixed but unknown subset of action profiles are successes and all other action profiles are failures. The game is played until either there is a success or the time horizon is reached. For any time horizon, including infinity, we demonstrate existence of optimal attainable strategies and show that they are Nash equilibria. For some time horizons, we can solve explicitly for the optimal attainable strategies and show uniqueness. The solution connects the learning behavior of agents to the fundamentals that characterize the organization: Agents in the organization respond more slowly to failure as the future becomes more important, the size of the organization increases and the probability of success decreases.Game theory

    Contains fulltext : 69574.pdf (publisher's version ) (Open Access)OBJECTIVE: To investigate the prevalence of detectable jugular lymphatic sacs in a setting for first trimester screening for Down syndrome, and to evaluate the influence of jugular lymphatic sacs on the screening performance for chromosomal abnormalities. METHODS: A prospective single center study (Erasmus University Medical Center, Rotterdam, The Netherlands) over a period of one year (January 2003-February 2004). First trimester nuchal translucency measurement was performed in a study population of 415 fetuses. Additionally, the transversal plane with the spine and mandible was visualized to verify the presence of jugular lymphatic sacs. The jugular lymphatic sacs were measured anterior-posterior. The association between nuchal translucency and jugular lymphatic sacs was tested. RESULTS: Follow-up was complete in 406 cases (97.8%). Jugular lymphatic sacs could be visualized in 98 out of 415 (23.5%). The nuchal translucency thickness and the mean of the left and right jugular lymphatic sac were significantly correlated. CONCLUSION: The sonographic visualization of jugular lymphatic sacs significantly predicts chromosomal abnormalities, although nuchal translucency is a better predictor. Nuchal translucency and jugular lymphatic sacs are strongly correlated and therefore not applicable in a combination test

    In Curaçao a systematic and comprehensive investigation of numerous factors, potentially associated with an increased risk of foetal and neonatal mortality, was carried out in a 2-year period (1984-1985). The inquiry was restricted to singleton births. Data on 205 women who experienced pregnancy loss were compared with those on 913 women who did not sustain foetal or neonatal loss. Data comprised information on maternal characteristics, clinical course of pregnancy and delivery, and neonatal characteristics. Of 130 factors measured, 14 were entered into a multivariate analysis. From the analysis 5 risk factors emerged as significant predictors of mortality: gestational age, birth weight, sex, foetal presentation and congenital anomalies. Factors such as social class, marital status, maternal age and parity were not associated with an increased risk of foetal and neonatal mortality in Curaçao.foetal mortality neonatal mortality risk factors Curacao West Indies

    Ethnic differences in informed decision-making about prenatal screening for Down's syndrome

    BACKGROUND: The aim of this study was to assess ethnic variations in informed decision-making about prenatal screening for Down's syndrome and to examine the contribution of background and decision-making variables. METHODS: Pregnant women of Dutch, Turkish and Surinamese origin were recruited between 2006 and 2008 from community midwifery or obstetrical practices in The Netherlands. Each woman was personally interviewed 3 weeks (mean) after booking for prenatal care. Knowledge, attitude and participation in prenatal screening were assessed following the 'Multidimensional Measure of Informed Choice' that has been developed and applied in the UK. RESULTS: In total, 71% of the Dutch women were classified as informed decision-makers, compared with 5% of the Turkish and 26% of the Surinamese women. Differences between Surinamese and Dutch women could largely be attributed to differences in educational level and age. Differences between Dutch and Turkish women could mainly be attributed to differences in language skills and gender emancipation. CONCLUSION: Women from ethnic minority groups less often made an informed decision whether or not to participate in prenatal screening. Interventions to decrease these ethnic differences should first of all be aimed at overcoming language barriers and increasing comprehension among women with a low education level. To further develop diversity-sensitive strategies for counselling, it should be investigated how women from different ethnic backgrounds value informed decision-making in prenatal screening, what decision-relevant knowledge they need and what they take into account when considering participation in prenatal screenin

    Item does not contain fulltextOBJECTIVE: To evaluate seroprevalence of anti-parvovirus B19 IgG immunoglobulins and the rate of seroconversion in seronegative pregnant women. DESIGN: Prospective assessment of anti-parvovirus B19 IgG immunoglobulins in an unselected population of pregnant women booked for antenatal care from 1998 to 2000. SETTING: Maternity departments of an academic hospital and four affiliated teaching hospitals in the Netherlands. SUBJECTS: Two thousand five hundred and sixty seven pregnant women. MAIN OUTCOME MEASURES: Seroprevalence of anti-parvovirus B19 IgG immunoglobulin in the first trimester of pregnancy and subsequent seroconversion in those women who were tested negative for parvovirus B19 antibodies in the first trimester of pregnancy. RESULTS: The estimated seroprevalence of anti-parvovirus B19 IgG immunoglobulins among the study population is 70% (95% CI: 68-71) in the first trimester of pregnancy. Seven hundred and seventy nine women tested negative for parvovirus B19 antibodies in the first trimester of pregnancy. Paired testing in these women confirmed 18 seroconversions. Based on these findings the estimated incidence of maternal parvovirus B19 infection in this population among seronegative Dutch women is 2.4% (95% CI: 1.4-3.7). CONCLUSION: Maternal infection with parvovirus B19 is relatively common. However, it is argued that in the Netherlands routine assessment of parvovirus antibodies in pregnant women is not warranted as there is a low risk of adverse fetal outcome and measures to prevent the parvovirus B19 infection and its consequences are very limited
