HIV-infection and modern antiretroviral therapy impair sperm quality

PurposeSerodiscordant couples with a human immunodeficiency virus type 1 (HIV-1)-infected man request assisted reproductive technology (ART) in order to achieve safe conception. Most of these men are on highly active antiretroviral therapy (HAART). HIV-1 infection and the antiretroviral drugs are blamed for semen alterations. The aim of our study was to investigate the semen parameters in HIV-1-infected patients with and without HAART and to compare their sperm characteristics with those of healthy men.Materials and methodsA prospective study of 226 men attended the university fertility center of Mannheim between May 1996 and July 2003. The patients were divided into three groups: HIV-infected men taking antiretroviral therapy, HIV-infected patients who did not take antiretroviral therapy until now and a control group with 93 men consulting our fertility center together with their wives because of tubal sterility. Semen samples were examined with regard to ejaculate volume, sperm concentration, motility, and morphology.ResultsThe study showed significant differences between the ejaculate of HIV-infected and non-infected men. The HIV-infected men as a whole group and the subgroup of men with HAART had a lower ejaculate volume, less slow progressive and more abnormally shaped spermatozoa compared with the control group. The HIV-infected men without an antiretroviral therapy had a significant lower ejaculate volume compared with the control group; the other parameters were not altered significantly. Differences between the subgroups with and without HAART were not significant.ConclusionThe spermiogram in HIV-1-infected men in comparison to a control group of healthy men is negatively altered. Especially in men with HAART, ejaculate volume as well as sperm morphology and motility changed significantly.

Associated malformations in congenital diaphragmatic hernia.

Congenital diaphragmatic hernia (CDH) is a severe neonatal anomaly. The aim of this study was to evaluate the frequency and types of malformations associated with CDH. The outcome was compared with that in newborns with CDH alone. The study included 362 fetuses and newborns at a single national center for CDH. Associated malformations and chromosomal aberrations were noted prenatally and postnatally. The neonatal outcome was assessed relative to the use of extracorporeal membrane oxygenation (ECMO) and the mortality rate. At least one associated malformation was diagnosed in 143 cases (39.5%). Altogether, 272 associated malformations were found. Only 50 (18.4%) anomalies were diagnosed antenatally. In 62 (17.1%) cases, 102 major malformations were found along with CDH, with a prenatal detection rate of 35.3%. The associated malformations were very heterogeneous, but cardiovascular malformations were the most common. Newborns with major anomalies, chromosomal aberrations, or syndromes additional to CDH had a significantly lower survival rate than newborns with an isolated CDH. Associated malformations did not affect the rate of ECMO treatment. Associated malformations in CDH are frequent and heterogeneous, and diligent and experienced antenatal and postnatal care is important.

Mode of delivery and its influence on women's satisfaction with childbirth

OBJECTIVE Many factors affect womens satisfaction with the experience of childbirth. Some of these are known, but most have not been fully evaluated. The influence of the mode of delivery is unclear. This study investigated the extent to which satisfaction with childbirth depends on the mode of delivery, and evaluated factors determining postpartum satisfaction. STUDY DESIGN Women with singleton pregnancies at term were included prospectively. After childbirth, all women meeting the inclusion criteria received a standardised questionnaire - the German version of Salmons Item List (SIL-Ger) - for completion before discharge to evaluate the birth experience. The chi-squared test, Fishers exact test, and Kruskal-Wallis test were used for statistical analysis. Univariate and multivariate linear regression analyses were used to assess associations between demographic and pregnancy-associated variables and variables influencing the perception of childbirth in the total SIL-Ger score. Univariate and multivariate binary logistic regression models were used to evaluate effects of demographic and clinical parameters on SIL-Ger scores of <70 versus SIL-Ger scores of ≥ 70. All covariates with a P value ≤ 0.10 in the univariate analysis were included in multivariate logistic regression models. All tests were two-sided, and P values<0.05 were considered statistically significant. RESULTS The analysis included 335 questionnaires. No differences were observed between different modes of delivery (normal 84.5 ± 14.6, primary caesarean 87.0 ± 13.5, secondary caesarean 83.2 ± 13.8, emergency caesarean 79.3 ± 7.3, operative vaginal delivery 83.9 ± 13.6; P=0.503). Multivariate analysis identified two independent factors associated with higher SIL-Ger scores: good/very good satisfaction with childbirth (P<0.001) and good/very good involvement in decision-making afterwards (P=0.005). Severe pain perception during childbirth was associated with lower SIL-Ger scores (P=0.003). Absence of a person of trust during childbirth was linked with scores<70 (P=0.005), indicating a negative experience. Good/very good satisfaction with childbirth (P<0.001) reduced the probability of a score<70. CONCLUSION Mode of delivery does not directly influence womens satisfaction with childbirth. Involvement in decision-making, support during labour and effective analgesia appear to be the most important factors that improve womens birth experience.

Clinical aspects of intraoperative radiotherapy in early breast cancer: short-term complications after IORT in women treated with low energy x-rays

BackgroundTo assess postoperative complications, clinical outcome and histological findings in patients undergoing intraoperative radiotherapy with low energy x-rays for early breast cancer.MethodsWe retrospectively analysed data of 208 women who underwent intraoperative irradiation during breast conserving surgery (BCS) between 2002 and 2007. Demographic, clinical and surgical parameters as well as short-term complications within the first postoperative week and histological findings were evaluated. Toxicities were assessed using the CTC/EORTC Score.ResultsPostoperative complications were rare and the immediate toxicity low, without any grade 3/4 acute toxicity. The most frequent postoperative side effects were suggillation (24%) and palpable seroma (17.3%). In 78.6% of the axillary seroma and in 25% of the breast seroma a needle aspiration was inevitable. Erythema grade I-II of the breast was found in 27 women (13%); whereas in 7 patients (3.4%), mastitis was confirmed. In 57.7% of the cases, the pathological assessment revealed ductal invasive breast cancer and tumour size ranged between 0.1 and 4.5 cm (mean = 1.6 cm).ConclusionIORT using Intrabeam® during BCS is safe, although it is associated with postoperative adverse events such as seroma. These should be mentioned and explained to women in detail during the preoperative discussion. This explicitly clinical description is useful for daily clinical practice; especially for giving a detailed analysis of the postoperative side effects during preoperative counselling.

Combination of misoprostol and mechanical dilation for induction of labour: a randomized controlled trial.

OBJECTIVE To evaluate a combination of oral misoprostol (OM) and mechanical dilation of the cervix to improve efficacy in inducing labour. STUDY DESIGN This prospective, randomized study included 122 term pregnancies with an indication for induced labour. Each woman was randomly assigned to one of two groups. In the study group, a combination of OM and mechanical dilation with a double-balloon catheter for cervical ripening was used. In the control group, only OM was administered. The primary outcome measure was the rate of failure to induce labour, defined as no vaginal delivery within 48h. RESULTS In the study group, the rate of failure to induce labour was significantly lower in comparison with the control group (9.3% vs. 21.2%; P=0.007). The median times for inducing labour were 15.3h in the study group and 20.8h in the control group (P=0.158). There were no significant differences between the two groups with regard to other outcome parameters. As there were no failures of induced labour among women with premature rupture of membranes, the study results were also evaluated after excluding these cases. Among those women without rupture of membranes, the median times for induction were 15.8h in the study group and 32.6h in the control group (P=0.024). The rates of failure to induce labour were 10.8% vs. 28.2% (P=0.002). CONCLUSION A combination of OM and a double-balloon catheter improves the efficacy of labour induction in term pregnancies, particularly in women without premature rupture of the membranes.

What are the limits of accuracy in fetal weight estimation with conventional biometry in two-dimensional ultrasound? A novel postpartum study

Commonly used formulae for fetal weight estimation, including combinations of several biometric parameters, lack accuracy despite efforts to improve them. This study aimed to investigate the limits of fetal weight estimation based on conventional biometric parameters on two‐dimensional (2D) ultrasound by developing and evaluating new weight equations using postpartum biometric parameters.

Sequential use of double‐balloon catheter and oral misoprostol versus oral misoprostol alone for induction of labour at term (CRBplus trial): a multicentre, open‐label randomised controlled trial

To evaluate the efficacy of inducing labour using a double‐balloon catheter and oral misoprostol sequentially, in comparison with oral misoprostol alone.

Periodic MRI Lung Volume Assessment in Fetuses With Congenital Diaphragmatic Hernia: Prediction of Survival, Need for ECMO, and Development of Chronic Lung Disease

OBJECTIVE The purpose of the study was to investigate the ability to predict survival, need for extracorporeal membrane oxygenation (ECMO), and incidence of chronic lung disease in patients with congenital diaphragmatic hernia in the context of a classification into three different times of gestation (< 28, 28-32, and > 32 weeks) by assessing the ratio between observed and expected MRI fetal lung volume. MATERIALS AND METHODS The data analysis included 226 fetuses with congenital diaphragmatic hernia. MRI was performed at different times of gestation with a T2-weighted HASTE sequence. Receiver operating characteristic curve analysis was performed to investigate the prognostic value of assessment of the ratio between observed and expected MRI fetal lung volumes at different stages of fetal growth. RESULTS For all reviewed times of gestation, the ratio between observed and expected MRI fetal lung volumes had almost equivalent statistically significant differences for neonatal survival (p ≤ 0.0029), need for ECMO therapy (p ≤ 0.0195), and development of chronic lung disease (p ≤ 0.0064). Results with high prognostic accuracy for early and for medium and late times in gestation also were obtained. Receiver operating characteristic analysis showed the highest area under the curve (≥ 0.819) for neonatal survival. CONCLUSION In patients with congenital diaphragmatic hernia, the relation between observed and expected MRI fetal lung volume is a valuable prognostic parameter for predicting neonatal mortality, morbidity represented by the development of chronic lung disease, and the need for ECMO therapy in early gestation (< 28 weeks) as well as later gestation with no statistically significant differences.

Single deepest vertical pocket or amniotic fluid index as evaluation test for predicting adverse pregnancy outcome (SAFE trial): a multicenter, open‐label, randomized controlled trial

To determine whether the amniotic fluid index (AFI) or the single deepest vertical pocket (SDP) technique for estimating amniotic fluid volume is superior for predicting adverse pregnancy outcome.

MRI-based ratio of fetal lung volume to fetal body volume as a new prognostic marker in congenital diaphragmatic hernia.

OBJECTIVE The objective of our study was to evaluate the prognostic accuracy of the MRI-based ratio of fetal lung volume (FLV) to fetal body volume (FBV) for predicting survival and the need for extracorporeal membrane oxygenation (ECMO) therapy in fetuses with congenital diaphragmatic hernia (CDH). MATERIALS AND METHODS MRI was performed in 96 fetuses (34 females and 62 males; mean gestational age, 33 ± 5 [SD] weeks; range, 23-39 weeks) with CDH and 44 healthy control subjects. FLV and FBV were measured for each fetus by one of three investigators, and we calculated the FLV/FBV ratio. Additionally, a subgroup analysis of growth-restricted fetuses was performed. Logistic regression analysis was used to model the dependence of survival and ECMO requirement on the FLV/FBV ratio. Prognostic accuracy was evaluated by applying the area under the curve (AUC). RESULTS Seventy-eight of the 96 (81%) fetuses survived and 35 (36%) neonates needed ECMO therapy. The FLV/FBV ratio was significantly higher in fetuses who survived (p < 0.0001; AUC = 0.829). Neonates who received ECMO therapy showed a significantly lower prenatal FLV/FBV ratio (p = 0.0001; AUC = 0.811) than neonates who did not need ECMO therapy. A subgroup analysis (n = 13) showed a trend toward a higher FLV/FBV ratio of survivors in comparison with nonsurvivors (p = 0.065; AUC = 0.875). CONCLUSION In our study, the MRI-based FLV/FBV ratio was able to predict neonatal survival and ECMO requirement in children with CDH with high accuracy. Unlike other prognostic parameters, FLV/FBV ratio is independent of a reference to a control group and may enhance prognostic accuracy particularly in growth-restricted neonatal patients.
