Our survey emphasizes the high rate of pregnancy-related listeriosis in Israel and shows that specific clones might account for this.

BackgroundIVF cycles which result in only one good quality embryo, and a second poor quality embryo present a dilemma when the decision involves transferring two embryos. The aim of this study was to evaluate whether a poor quality embryo has a negative effect on a good quality embryo when transferred along with a good quality embryo.MethodsWe retrospectively evaluated in vitro fertilization (IVF) cycles involving single embryo transfers (SET) and double embryo transfers (DET). Embryo quality was divided into poor “P” and good “G” quality. The main outcome measures were: live birth, implantation rate, miscarriage rate, clinical pregnancy rate and multiple pregnancy ratio.ResultsSix hundred three women were included. The study group consisted of 180 (29.9%) patients who had a double embryo transfer (DET) with one poor quality embryo and one good quality embryo (P + G). Control 1 group included 303 (50.2%) patients who had DET with two good quality embryos (G + G), and control 2 group consisted of 120 (19.9%) patients who had a single embryo transfer (SET) with one good quality embryo (G). Live birth rates were not significantly different when compared between study groups: 30.8% in the SET group (G), 27.2% in the (G + P) group and 33.7% in the (G + G) group. The SET group had the highest implantation rate (33.9%) compared to the DET groups (21.8% (G + P), 25.4% (G + G)) (P =0.022). The clinical pregnancy rate was 33.3% in the SET group (G), 33.3% in the (G + P) group, and 39.3% in the (G + G) group (P =0.39). The miscarriage rate was comparable in all groups.ConclusionA poor quality embryo does not negatively affect a good quality embryo, when transferred together in a double embryo transfer.Electronic supplementary materialThe online version of this article (doi:10.1186/s13048-016-0297-9) contains supplementary material, which is available to authorized users.

BackgroundNeutrophils to lymphocytes ratio (NLR) and platelets to lymphocytes ratio (PLR) are both inflammatory ratios that can be easily calculated from a simple blood count. They are frequently reported and tested as prognostic factors in several medical disciplines. Pregnancy involves special reference values for laboratory assays.ObjectiveThe aim of this study was to define pregnancy-related reference values for NLR and PLR according to trimester, background morbidity and according to the patient's age.Study designA retrospective analysis of a large cohort undergoing community-based pregnancy surveillance between the years 2011–2016. Data were analyzed according to high-risk patient versus normal-risk patient.ResultsA total of 11,415 patients were included. Mean PLR and NLR values were 136.3±44.3, 2.6±1, respectively during the first trimester, 144.6±47.1, 4.0±1.4 respectively during the second trimester and 118.1±42.0, 3.5±1.2 respectively during the third trimester. No difference was detected between the high-risk and the normal population (P-values 0.3, 0.5 and 0.4 for PLR in each trimester respectively and 0.3, 0.4, 0.6 for NLR in each trimester, respectively). No differences were detected among parity categories. The correlation between patient’s age and either PLR and NLR was a weak positive correlation (though statistically significant). Both PLR and NLR reached a maximum value during the second trimester. The differences between mean NLR and PLR between trimesters were significant (P <0.01 for all differences tested). PLR rises in the presence of anemia, reaching statistical significance (P-value for PLR in each trimester was <0.01). NLR showed an opposite trend (P-values for NLR were 0.4, 0.005 and 0.06 in each trimester, respectively).ConclusionsIn our cohort, there were generally no differences between the high-risk and the normal population, excluding patients with a fibroid uterus or inflammatory bowel disease who presented a significantly elevated PLR through all trimesters. Both PLR and NLR reached a maximum value during the second trimester and were positively correlated with age. We anticipate that the population-based data will assist in providing accurate reference values for future research testing NLR and PLR measures during pregnancy.

Ovarian hyperstimulation syndrome (OHSS) is a serious and potentially life-threatening complication of fertility treatment. This study evaluated pregnancy outcomes of women hospitalized for severe OHSS. A case-control study was performed of 125 women who were hospitalized due to severe OHSS compared with a control group, consisting of 156 women matched by age and aetiology of infertility, who conceived via IVF and did not develop OHSS. Among women with singleton pregnancies, patients with severe OHSS delivered significantly earlier (37.96 versus 39.11 weeks) and had smaller babies (2854 g versus 3142 g) compared with the matched controls. Similarly, rates of preterm delivery (<34 weeks of gestation: 8.9% versus 0%, P < 0.01; <37 weeks of gestation: 20.5% versus 5.1%, P < 0.01) were significantly increased among patients in the study group. There were no between-group differences in the rates of gestational diabetes, gestational hypertension and intrauterine growth restriction. In contrast, twin pregnancies following OHSS were not significantly different from matched control twins, with regard to the rates of delivery <34 weeks and <37 weeks of gestation, gestational diabetes, gestational hypertension and intrauterine growth restriction. In conclusion, severe OHSS at early gestation is associated with adverse pregnancy outcome only in singleton gestations.

Diastolic dysfunction may influence perioperative outcome, early graft function, and long-term survival. We compared the outcomes of double lung transplantation (DLTx) for patients with pulmonary arterial hypertension (PAH) with preoperative left ventricular (LV) diastolic dysfunction with the outcomes of patients without diastolic dysfunction. Of 116 consecutive patients with PAH (who underwent transplantation between January 1995 and December 2013), 44 met our inclusion and exclusion criteria. Fourteen (31.8%) patients with diastolic dysfunction pretransplantation had a higher body mass index (29 [IQR 21.5-32.6] vs 22.4 [IQR 19.9-25.3] kg/m ) and mean pulmonary arterial pressure (54.6 ± 10 mmHg vs 47 ± 11.3 mmHg) and right atrial pressure (16.5 ± 5.2 mmHg vs 10.6 ± 5.2 mmHg). The patients received extracorporeal life support more frequently (33% vs 7% [p = 0.02]), had worse APACHE II scores (21.7 ± 7.4 vs 15.3 ± 5.3 [p = 0.02]), and a trend toward worse ventilator-free days (2.5 [IQR 6.5-32.5] vs 17 [IQR 3-23] [p = 0.08]). There was no effect on development of primary graft dysfunction or intensive care unit/hospital survival. One-year survival was worse (hazard ratio [HR] 4.45, 95% confidence interval [CI] 1.3-22, p = 0.02). Diastolic dysfunction was the only variable that correlated with overall survival (HR 5.4, 95% CI 1.3-22, p = 0.02). Diastolic dysfunction leads to early postoperative morbidity and worse survival in patients with PAH after DLTx.
