Diagnosis and treatment of iron-deficiency anaemia in pregnancy and postpartum.

Iron deficiency occurs frequently in pregnancy and can be diagnosed by serum ferritin-level measurement (threshold value < 30 µg/L). Screening for iron-deficiency anemia is recommended in every pregnant women, and should be done by serum ferritin-level screening in the first trimester and regular hemoglobin checks at least once per trimester. In the case of iron deficiency with or without anaemia in pregnancy, oral iron therapy should be given as first-line treatment. In the case of severe iron-deficiency anemia, intolerance of oral iron, lack of response to oral iron, or in the case of a clinical need for rapid and efficient treatment of anaemia (e.g., advanced pregnancy), intravenous iron therapy should be administered. In the postpartum period, oral iron therapy should be administered for mild iron-deficiency anemia (haemorrhagic anemia), and intravenous iron therapy for moderately severe-to-severe anemia (Hb < 95 g/L). If there is an indication for intravenous iron therapy in pregnancy or postpartum, iron-containing drugs which have been studied in well-controlled clinical trials in pregnancy and postpartum such as ferric carboxymaltose must be preferred for safety reasons. While anaphylactic reactions are extremely are with non-dextrane products, close surveillance during administration is recommended for all intravenous iron products.

Emergence of Acquired HIV-1 Drug Resistance Almost Stopped in Switzerland: A 15-Year Prospective Cohort Analysis.

BACKGROUND: Drug resistance is a major barrier to successful antiretroviral treatment (ART). Therefore, it is important to monitor time trends at a population level. METHODS: We included 11 084 ART-experienced patients from the Swiss HIV Cohort Study (SHCS) between 1999 and 2013. The SHCS is highly representative and includes 72% of patients receiving ART in Switzerland. Drug resistance was defined as the presence of ≥1 major mutation in a genotypic resistance test. To estimate the prevalence of drug resistance, data for patients with no resistance test was imputed based on the patient's risk of harboring drug-resistant viruses. RESULTS: The emergence of new drug resistance mutations declined dramatically from 401 to 23 patients between 1999 and 2013. The upper estimated prevalence limit of drug resistance among ART-experienced patients decreased from 57.0% in 1999 to 37.1% in 2013. The prevalence of 3-class resistance decreased from 9.0% to 4.4% and was always <0.4% for patients who initiated ART after 2006. Most patients actively participating in the SHCS in 2013 with drug-resistant viruses initiated ART before 1999 (59.8%). Nevertheless, in 2013, 94.5% of patients who initiated ART before 1999 had good remaining treatment options based on Stanford algorithm. CONCLUSIONS: Human immunodeficiency virus type 1 drug resistance among ART-experienced patients in Switzerland is a well-controlled relic from the era before combination ART. Emergence of drug resistance can be virtually stopped with new potent therapies and close monitoring.

HIV-1 Transmission During Recent Infection and During Treatment Interruptions as Major Drivers of New Infections in the Swiss HIV Cohort Study.

BACKGROUND: Reducing the fraction of transmissions during recent human immunodeficiency virus (HIV) infection is essential for the population-level success of "treatment as prevention". METHODS: A phylogenetic tree was constructed with 19 604 Swiss sequences and 90 994 non-Swiss background sequences. Swiss transmission pairs were identified using 104 combinations of genetic distance (1%-2.5%) and bootstrap (50%-100%) thresholds, to examine the effect of those criteria. Monophyletic pairs were classified as recent or chronic transmission based on the time interval between estimated seroconversion dates. Logistic regression with adjustment for clinical and demographic characteristics was used to identify risk factors associated with transmission during recent or chronic infection. FINDINGS: Seroconversion dates were estimated for 4079 patients on the phylogeny, and comprised between 71 (distance, 1%; bootstrap, 100%) to 378 transmission pairs (distance, 2.5%; bootstrap, 50%). We found that 43.7% (range, 41%-56%) of the transmissions occurred during the first year of infection. Stricter phylogenetic definition of transmission pairs was associated with higher recent-phase transmission fraction. Chronic-phase viral load area under the curve (adjusted odds ratio, 3; 95% confidence interval, 1.64-5.48) and time to antiretroviral therapy (ART) start (adjusted odds ratio 1.4/y; 1.11-1.77) were associated with chronic-phase transmission as opposed to recent transmission. Importantly, at least 14% of the chronic-phase transmission events occurred after the transmitter had interrupted ART. CONCLUSIONS: We demonstrate a high fraction of transmission during recent HIV infection but also chronic transmissions after interruption of ART in Switzerland. Both represent key issues for treatment as prevention and underline the importance of early diagnosis and of early and continuous treatment.

Detection of newly antibody-defined epitopes on HLA class I alleles reacting with antibodies induced during pregnancy.

The determination of HLA mismatch acceptability at the epitope level can be best performed with epitopes that have been verified experimentally with informative antibodies. The website-based International Registry of HLA Epitopes (http://www.epregistry.com.br) has a list of 81 antibody-verified HLA-ABC epitopes but more epitopes need to be added. Pregnancy offers an attractive model to study antibody responses to mismatched HLA epitopes which can be readily determined from the HLA types of child and mother. This report describes a HLAMatchmaker-based analysis of 16 postpregnancy sera tested in single HLA-ABC allele binding assays. Most sera reacted with alleles carrying epitopes that have been antibody-verified, and this study focused on the reactivity of additional alleles that share other epitopes corresponding to eplets and other amino acid residue configurations. This analysis led in the identification of 16 newly antibody-defined epitopes, seven are equivalent to eplets and nine correspond to combinations of eplets in combination with other nearby residue configurations. These epitopes will be added to the repertoire of antibody-verified epitopes in the HLA Epitope Registry.

[Ambulant Management in Case of Premature Rupture of Membranes (PROM) at Term: Maternal and Perinatal Outcome]. / Ambulantes Management bei vorzeitigem Blasensprung (VBS) am Termin. Eine Outcome-Analysestudie bei ambulantem vs. stationärem Management.

Introduction: It is estimated that after premature rupture of membranes (PROM) at term, 60% of all women go into labour within 48 h, 95% within 72 h. Often labour is induced after 24 h because the risk of maternal and neonatal infection rises. The majority of clinicians advise hospital care to allow monitoring and detection of problems. But for low-risk patients who meet strict inclusion criteria, sometimes home management is possible. This study examines the safety and costs of home management. Material and Methods: We included 239 patients with PROM at term, 202 of them with hospital and 37 with home management. Patients who met the inclusion criteria were checked 12 h after PROM and were induced by the end of 24 h if labour had not begun spontaneously. Results: There were no differences in maternal or neonatal outcome. Women with home management were likely to spend less time in hospital and this was associated with reduced costs. Conclusion: Women with outpatient management of PROM had a shorter hospitalization stay without negative impact on maternal or fetal outcome. In times of increasing financial pressure on the medical system, outpatient management for PROM seems to be a viable option.

Predicted Indirectly Recognizable HLA Epitopes Presented by HLA-DRB1 Are Related to HLA Antibody Formation During Pregnancy.

Pregnancy can prime maternal immune responses against inherited paternal HLA of the fetus, leading to the production of child-specific HLA antibodies. We previously demonstrated that donor-specific HLA antibody formation after kidney transplantation is associated with donor-derived HLA epitopes presented by recipient HLA class II (predicted indirectly recognizable HLA epitopes presented by HLA class II [PIRCHE-II]). In the present study, we evaluated the role of PIRCHE-II in child-specific HLA antibody formation during pregnancy. A total of 229 mother-child pairs were HLA typed. For all mismatched HLA class I molecules of the child, we subsequently predicted the number of HLA epitopes that could be presented by maternal HLA class II molecules. Child-specific antigens were classified as either immunogenic or nonimmunogenic HLA based on the presence of specific antibodies and correlated to PIRCHE-II numbers. Immunogenic HLA contained higher PIRCHE-II numbers than nonimmunogenic HLA. Moreover, the probability of antibody production during pregnancy increased with the number of PIRCHE-II. In conclusion, our data suggest that the number of PIRCHE-II is related to the formation of child-specific HLA antibodies during pregnancy. Present confirmation of the role of PIRCHE-II in antibody formation outside the transplantation setting suggests the PIRCHE-II concept is universal.

Prevention of preterm delivery with vaginal progesterone in women with preterm labour (4P): randomised double-blind placebo-controlled trial.

OBJECTIVE: To evaluate the effectiveness of 200 mg of daily vaginal natural progesterone to prevent preterm birth in women with preterm labour. DESIGN: Multicentre, randomised, double-blind, placebo-controlled trial. SETTING: Twenty-nine centres in Switzerland and Argentina. POPULATION: A total of 385 women with preterm labour (24(0/7) to 33(6/7) weeks of gestation) treated with acute tocolysis. METHODS: Participants were randomly allocated to either 200 mg daily of self-administered vaginal progesterone or placebo within 48 hours of starting acute tocolysis. MAIN OUTCOME MEASURES: Primary outcome was delivery before 37 weeks of gestation. Secondary outcomes were delivery before 32 and 34 weeks, adverse effects, duration of tocolysis, re-admissions for preterm labour, length of hospital stay, and neonatal morbidity and mortality. The study was ended prematurely based on results of the intermediate analysis. RESULTS: Preterm birth occurred in 42.5% of women in the progesterone group versus 35.5% in the placebo group (relative risk [RR] 1.2; 95% confidence interval [95% CI] 0.93-1.5). Delivery at <32 and <34 weeks did not differ between the two groups (12.9 versus 9.7%; [RR 1.3; 95% CI 0.7-2.5] and 19.7 versus 12.9% [RR 1.5; 95% CI 0.9-2.4], respectively). The duration of tocolysis, hospitalisation, and recurrence of preterm labour were comparable between groups. Neonatal morbidity occurred in 44 (22.8%) cases on progesterone versus 35 (18.8%) cases on placebo (RR: 1.2; 95% CI 0.82-1.8), whereas there were 4 (2%) neonatal deaths in each study group. CONCLUSION: There is no evidence that the daily administration of 200 mg vaginal progesterone decreases preterm birth or improves neonatal outcome in women with preterm labour.

[Management of postpartum hemorrhage (PPH): algorithm of the interdisciplinary D-A-CH consensus group PPH (Germany - Austria - Switzerland)]. / Management der postpartalen Blutung (PPH): Algorithmus der Interdisziplinären D-A-CH-Konsensusgruppe PPH (Deutschland - Österreich - Schweiz).

Postpartum hemorrhage (PPH) is one of the main causes of maternal deaths even in industrialized countries. It represents an emergency situation which necessitates a rapid decision and in particular an exact diagnosis and root cause analysis in order to initiate the correct therapeutic measures in an interdisciplinary cooperation. In addition to established guidelines, the benefits of standardized therapy algorithms have been demonstrated. A therapy algorithm for the obstetric emergency of postpartum hemorrhage in the German language is not yet available. The establishment of an international (Germany, Austria and Switzerland D-A-CH) "treatment algorithm for postpartum hemorrhage" was an interdisciplinary project based on the guidelines of the corresponding specialist societies (anesthesia and intensive care medicine and obstetrics) in the three countries as well as comparable international algorithms for therapy of PPH.The obstetrics and anesthesiology personnel must possess sufficient expertise for emergency situations despite lower case numbers. The rarity of occurrence for individual patients and the life-threatening situation necessitate a structured approach according to predetermined treatment algorithms. This can then be carried out according to the established algorithm. Furthermore, this algorithm presents the opportunity to train for emergency situations in an interdisciplinary team.

Frequency and determinants of pregnancy-induced child-specific sensitization.

The aim of this study was to define the frequency and determinants of pregnancy-induced child-specific sensitization shortly after full-term delivery using sensitive single HLA-antigen beads (SAB) and high resolution HLA-typing of the mothers and their children (n = 301). A positive SAB result was defined by a background normalized ratio >1 or a mean fluorescence intensity (MFI) >300, >500 and >1000, respectively. The overall frequency of pregnancy-induced sensitization determined by SAB shortly after full-term delivery was between 45% (MFI > 1000 cut-off) and 76% (ratio cut-off). The rate of child-specific sensitization at the HLA-A/B/C/DRB1 loci was between 28% (MFI > 1000 cut-off) and 38% (ratio cut-off). The number of live birth was associated with a higher frequency of sensitization, which was driven by child-specific, but not third party HLA-antibodies. There was a clear hierarchy of sensitization among the investigated loci (B-locus: 31%; A-locus: 26%; DRB1-locus: 20%; C-locus: 15%; p < 0.0001). Some mismatched paternal HLA-antigens led to a significantly higher rate of sensitization than the average (e.g. HLA-A2, HLA-B49, HLA-B51, HLA-C*15). Furthermore, the mother's own HLA-phenotype--especially HLA-A/B homozygosity--was associated with a higher rate and broadness of sensitization. The number of mismatched HLA-A/B/C eplets strongly correlated with the rate of child-specific class I sensitization.

[New aspects of obstetric anesthesia]. / Neues aus der geburtshilflichen Anästhesie.

BACKGROUND: The risk profile of patients in obstetric anesthesia has substantially changed. Even more so than other disciplines, obstetric anesthesia is therefore in the true sense of the word dependent on the close coordination of all concerned and a good interdisciplinary cooperation. AIM: This article explains the important anesthesiological risks connected with parturition and presents the corresponding concepts for prevention, diagnosis and management of peripartum complications. MATERIAL AND METHODS: The increase in the number of high risk pregnancies, which are mostly due to an increase in obesity, require clearly defined guidelines and interdisciplinary concepts which are described and discussed in this article. The neuraxial block is still the most effective procedure for treatment of birth pain and offers a promising new method with the programmed intermittent epidural boluses presented in this article. Finally, the German speaking countries Germany, Austria and Switzerland have developed a treatment algorithm for the management of postpartum hemorrhage which is presented here. RESULTS: The anesthesiological components of a risk pregnancy must be recognized early and include obesity, preeclampsia and drug-induced coagulopathy. Epidural analgesia is the most effective analgesic procedure in obstetrics. Patient-controlled remifentanil analgesia currently represents the best alternative in cases of contraindications for a neuraxial procedure. CONCLUSION: In risk situations, such as pre(eclempsia), emergency cesarean section, massive blood loss or other peripartum emergency situations, optimal interdisciplinary cooperation between midwives, obstetricians and anesthetists is required. However, not only emergency situations require a good interdisciplinary cooperation. Just as important is the cooperation to recognize risk pregnancies and a timely joint planning of the approaching birth.

High specificity of line-immunoassay based algorithms for recent HIV-1 infection independent of viral subtype and stage of disease.

BACKGROUND: Serologic testing algorithms for recent HIV seroconversion (STARHS) provide important information for HIV surveillance. We have shown that a patient's antibody reaction in a confirmatory line immunoassay (INNO-LIA HIV I/II Score, Innogenetics) provides information on the duration of infection. Here, we sought to further investigate the diagnostic specificity of various Inno-Lia algorithms and to identify factors affecting it. METHODS: Plasma samples of 714 selected patients of the Swiss HIV Cohort Study infected for longer than 12 months and representing all viral clades and stages of chronic HIV-1 infection were tested blindly by Inno-Lia and classified as either incident (up to 12 m) or older infection by 24 different algorithms. Of the total, 524 patients received HAART, 308 had HIV-1 RNA below 50 copies/mL, and 620 were infected by a HIV-1 non-B clade. Using logistic regression analysis we evaluated factors that might affect the specificity of these algorithms. RESULTS: HIV-1 RNA < 50 copies/mL was associated with significantly lower reactivity to all five HIV-1 antigens of the Inno-Lia and impaired specificity of most algorithms. Among 412 patients either untreated or with HIV-1 RNA ≥ 50 copies/mL despite HAART, the median specificity of the algorithms was 96.5% (range 92.0-100%). The only factor that significantly promoted false-incident results in this group was age, with false-incident results increasing by a few percent per additional year. HIV-1 clade, HIV-1 RNA, CD4 percentage, sex, disease stage, and testing modalities exhibited no significance. Results were similar among 190 untreated patients. CONCLUSIONS: The specificity of most Inno-Lia algorithms was high and not affected by HIV-1 variability, advanced disease and other factors promoting false-recent results in other STARHS. Specificity should be good in any group of untreated HIV-1 patients.

[Severe neonatal blood loss due to umbilical cord rupture in an underwater birth]. / Hämorrhagischer Schock eines Neugeborenen aufgrund Nabelschnurruptur während Unterwassergeburt.

BACKGROUND: We present the case of an intrapartum umbilical cord rupture in an underwater birth with severe neonatal blood loss. CASE REPORT: A healthy 25-year-old gravida I with an uneventful pregnancy had an underwater birth. A completed rupture of the umbilical cord was diagnosed immediately after the newborn surfaced from the water and was laid on the mother's chest. The newborn suffered from severe haemorrhage with bradycardia and respiratory distress. It was immediately resuscitated by the neonatologist. Intravenous donation of volume and red blood cell transfusion could stabilise the vital parameters. The newborn was discharged in a state of well-being 6 days postnatally. DISCUSSION: Cases of umbilical cord rupture are reported in relationship to land and water births. Common causes of a cord rupture include haematoma of the cord vessels, trauma from an operative vaginal delivery, funisitis with localised cord necrosis, velamentous cord insertions, tumours of the umbilical cord and a short umbilical cord. A suspicious foetal heart rate might be absent. In the case of a water birth complications bear serious consequences. Proper team work between obstetricians and neonatologists is essential. CONCLUSION: Although water birth is restricted to low risk patients, unforeseen complications may occur. Because of the special situation in an underwater birth complications may be diagnosed late and their management will be more difficult. Obstetricians should be aware of this risk.

["STUMP" (smooth muscle tumour of uncertain malignant potential), a tumour of the uterus in pregnancy--a diagnostic and therapeutic challenge]. / "STUMP" (smooth muscle tumor of uncertain malignant potential), ein Uterustumor in der Schwangerschaft, eine diagnostische und therapeutische Herausforderung.

We present the case of a preterm birth in the 27 (th) week of gestation, probably due to a chorionamnionitis, with the coincidental finding of a STUMP (smooth muscle tumour of uncertain malignant potential). The STUMP is a rare tumour entity characterised by smooth muscle cells which is difficult to classify by means of histology. The WHO classification of mesenchymal tumours allocates STUMP as an intermediate tumour between a benign leiomyoma and a malignant leiomyosarcoma. If histological criteria of malignancy are not fulfilled because the type of necrosis is in doubt or the interpretation of mitotic figures is ambiguous and the tumour cannot reliably be classified as a leiomyoma, it is classified as a STUMP. Compared to malignant leiomyosarcoma, STUMP has a superior prognosis, but the biological potential of the tumour remains unclear; lymphogenic and haematogenic dissemination seems possible even after a long period of time. STUMP represents a challenge in diagnosis and treatment recommendations. We present the first description of a case of STUMP during pregnancy, raising the question of whether the histological finding in tumours of the uterus during pregnancy are important.

Ropivacaine versus bupivacaine 0.125% with fentanyl 1 microg/ml for epidural labour analgesia: is daily practice more important than pharmaceutical choice?

UNLABELLED: Ropivacaine might be superior to bupivcaine for epidural labour analgesia because it appears to induce less lower extremity motor blockade. The clinical relevance of this difference is not yet clear. METHODS: In a double-blind randomised trial bupivacaine and ropivacaine each at 0.125% with 1 microg/ml fentanyl were compared for epidural labour analgesia. This study was performed in two university hospitals. RESULTS: Sixty-three nulliparous women with singleton pregnancies at term were included. There were no differences between bupivacaine and ropivacaine as far as motor blockade, analgesic outcome, mode of delivery and neonatal outcome are concerned. However, the clinical management of epidural analgesia differed significantly between the two institutions involved. Parturients of one institution had their epidural catheter placed earlier, needed less top-up medication, and had more successful mobilisations, when compared to the other institution. CONCLUSIONS: Institutional clinical practice can be significantly different. Pharmacological differences between bupivacaine and ropivacaine at 0.125% with 1 microg/ml fentanyl seem to be less important than differences between institutions in terms of clinical practice.

[Recent advances in prenatal diagnostics]. / Neue Möglichkeiten in der pränatalen Diagnostik.

During the last years, technical improvements have increased the possibilities in prenatal ultrasound. During the eighties and nineties, fetal malformations were increasingly detected and specified. Since a few years, the measurement of the fetal nuchal translucency between 11 and 14 weeks of gestation has been implemented to calculate the individual risk, in combination with most recent biochemical markers. Today, the sonographic measurement of the nuchal translucency is regarded as a valuable screening tool for chromosomal anomalies in prenatal medicine. Beside standardized examinations, a profound information and counseling of the pregnant women should be emphasized. With the improvement of the specific maternal risk calculation, using the sonographic measurement of the nuchal translucency, the biochemical markers and the maternal age, unnecessary invasive examinations may be prevented and their overall number can significantly be reduced. The same trend is seen in the whole field of prenatal medicine, illustrated by the detection of the fetal rhesus D status from the maternal blood and the use of Doppler ultrasound in the management of fetal anemia.

Increases in Condomless Sex in the Swiss HIV Cohort Study.

Condomless sex is a key driver of sexually transmitted diseases. In this study, we assess the long-term changes (2000-2013) of the occurrence of condomless sex among human immunodeficiency virus (HIV)-infected individuals enrolled in the Swiss HIV Cohort study. The frequencies with which HIV-infected individuals reported condomless sex were either stable or only weakly increasing for 2000-2008. For 2008-2013, these rates increased significantly for stable relationships among heterosexuals and men who have sex with men (MSM) and for occasional relationships among MSM. Our results highlight the increasing public health challenge posed by condomless sex and show that condomless sex has been increasing even in the most recent years.

Strong Impact of Smoking on Multimorbidity and Cardiovascular Risk Among Human Immunodeficiency Virus-Infected Individuals in Comparison With the General Population.

Background. Although acquired immune deficiency syndrome-associated morbidity has diminished due to excellent viral control, multimorbidity may be increasing among human immunodeficiency virus (HIV)-infected persons compared with the general population. Methods. We assessed the prevalence of comorbidities and multimorbidity in participants of the Swiss HIV Cohort Study (SHCS) compared with the population-based CoLaus study and the primary care-based FIRE (Family Medicine ICPC-Research using Electronic Medical Records) records. The incidence of the respective endpoints were assessed among SHCS and CoLaus participants. Poisson regression models were adjusted for age, sex, body mass index, and smoking. Results. Overall, 74 291 participants contributed data to prevalence analyses (3230 HIV-infected; 71 061 controls). In CoLaus, FIRE, and SHCS, multimorbidity was present among 26%, 13%, and 27% of participants. Compared with nonsmoking individuals from CoLaus, the incidence of cardiovascular disease was elevated among smoking individuals but independent of HIV status (HIV-negative smoking: incidence rate ratio [IRR] = 1.7, 95% confidence interval [CI] = 1.2-2.5; HIV-positive smoking: IRR = 1.7, 95% CI = 1.1-2.6; HIV-positive nonsmoking: IRR = 0.79, 95% CI = 0.44-1.4). Compared with nonsmoking HIV-negative persons, multivariable Poisson regression identified associations of HIV infection with hypertension (nonsmoking: IRR = 1.9, 95% CI = 1.5-2.4; smoking: IRR = 2.0, 95% CI = 1.6-2.4), kidney (nonsmoking: IRR = 2.7, 95% CI = 1.9-3.8; smoking: IRR = 2.6, 95% CI = 1.9-3.6), and liver disease (nonsmoking: IRR = 1.8, 95% CI = 1.4-2.4; smoking: IRR = 1.7, 95% CI = 1.4-2.2). No evidence was found for an association of HIV-infection or smoking with diabetes mellitus. Conclusions. Multimorbidity is more prevalent and incident in HIV-positive compared with HIV-negative individuals. Smoking, but not HIV status, has a strong impact on cardiovascular risk and multimorbidity.

Incident Hepatitis C Virus Infections in the Swiss HIV Cohort Study: Changes in Treatment Uptake and Outcomes Between 1991 and 2013.

Background. The hepatitis C virus (HCV) epidemic is evolving rapidly in patients infected with human immunodeficiency virus (HIV). We aimed to describe changes in treatment uptake and outcomes of incident HCV infections before and after 2006, the time-point at which major changes in HCV epidemic became apparent. Methods. We included all adults with an incident HCV infection before June 2012 in the Swiss HIV Cohort Study, a prospective nationwide representative cohort of individuals infected with HIV. We assessed the following outcomes by time period: the proportion of patients starting an HCV therapy, the proportion of treated patients achieving a sustained virological response (SVR), and the proportion of patients with persistent HCV infection during follow-up. Results. Of 193 patients with an HCV seroconversion, 106 were diagnosed before and 87 after January 2006. The proportion of men who have sex with men increased from 24% before to 85% after 2006 (P < .001). Hepatitis C virus treatment uptake increased from 33% before 2006 to 77% after 2006 (P < .001). Treatment was started during early infection in 22% of patients before and 91% after 2006 (P < .001). An SVR was achieved in 78% and 29% (P = .01) of patients treated during early and chronic HCV infection. The probability of having a detectable viral load 5 years after diagnosis was 0.67 (95% confidence interval [CI], 0.58-0.77) in the group diagnosed before 2006 and 0.24 (95% CI, 0.16-0.35) in the other group (P < .001). Conclusions. In recent years, increased uptake and earlier initiation of HCV therapy among patients with incident infections significantly reduced the proportion of patients with replicating HCV.

Oral misoprostol for third stage of labor: a randomized placebo-controlled trial.

OBJECTIVE: To investigate whether orally administered misoprostol during the third stage of labor is efficient in reducing postpartum blood loss. METHODS: In a double-masked trial, during vaginal delivery women were randomly assigned to receive a single oral dose of misoprostol (600 microg) or placebo in third stage of labor, immediately after cord clamping. The third stage of labor was managed routinely by early cord clamping and controlled cord traction; oxytocin was administered only if blood loss seemed more than usual. Blood loss was estimated by the delivering physician and differences in hematocrit were measured before and after delivery. RESULTS: Mean (+/- standard error of the mean) estimated blood loss (345 +/- 19.5 mL versus 417 +/- 25.9 mL, P = .031) and hematocrit difference (4.5 +/- 0.9% versus 7.9 +/- 1.2%, P = .014) were significantly lower in women who received misoprostol than those who received placebo. Fewer women in the misoprostol group had postpartum hemorrhage (blood loss of at least 500 mL), but that difference was not statistically significant (7% versus 15%, P = .43). Additional oxytocin before or after placental separation was used less often in the misoprostol group (16% versus 38%, P = .047). There were no differences in the length of third stage of labor (8 +/- 0.9 minutes versus 9 +/- 1 minutes, P = .947). There were no differences in pain during third stage of labor, postpartum fever, or diarrhea, but shivering was more frequent in the misoprostol group. CONCLUSION: Oral misoprostol administered in the third stage of labor reduced postpartum blood loss and might be effective in reducing incidence of postpartum hemorrhage.

Birth as a multidimensional experience: comparison of the English- and German-language versions of Salmon's Item List.

Results concerning satisfaction with the birth experience in different trials are difficult to compare, owing to a lack of internationally used research scales. Salmon's Item List (SIL) is easy-to-handle and would therefore be very helpful for research as well as for obstetric clinic quality control. Two hundred and fifty-one patients were investigated using a German-language version of SIL (SIL-ger); the statistical evaluation was carried out by means of a principal components analysis. Principal components analysis revealed two major findings: (1) as stated by other authors the birth experience is multidimensional, each aspect influencing the others in a non-linear way; (2) in addition to Salmon's dimensions (i.e. postnatal 'fulfillment', intranatal 'physical discomfort' and intranatal 'emotional distress') another postnatal dimension labeled 'negative emotional experience' was detected. Not only are intranatal experiences multidimensional, but so too are evaluative feelings afterwards. In addition to fulfillment, as developed by Salmon, a dimension of negative emotional experience needs to be taken into account. This dimension does not correlate in a linear way with fulfillment. It is appropriate to use SIL in research. Before using it for purposes of clinical quality control, however, larger samples need to be evaluated in order to prove the stability of the factor structure.
