The objective of this study was to evaluate the impact of one abnormal fetus in a twin pregnancy, to compare impact of chorionicity and clinical outcome of intervention and expectant management. Thirty-seven dichorionic (DC) twins and 18 monochorionic (MC) twins complicated with one malformed fetus were evaluated for gestational age, birthweight and perinatal outcome. Six hundred and forty-two twin pregnancies were evaluated in the database. The control groups consisted of 429 DC and 86 MC twins without anomalous fetus. Mean birthweight and gestational age at birth for DC control group were (n= 429; 2137g and 34.71 weeks), DC study group,n= 37; 2117g (p= .338) and 33.97 weeks (p= .311), and DC study group with major malformations,n= 30; 2019g (p= .289) and 33.3 weeks (p= .01), and showed only significance for gestational age. There was no statistical significance between MC control group,n= 86; 2097g and 34.93 weeks, and MC study group,n= 18; 2237g (p= .338), and 34.42 weeks (p= .502). Because of limited data, the preliminary evaluation for expectant management and intervention, and survival of at least one normal fetus showed no impact. We conclude that, although, all DC twin pregnancies have a risk for preterm delivery, DC twins complicated with major malformation of one twin, have a lower mean gestational age at birth. Preliminary results for intervention does not improve fetal outcome for DC and MC twins and needs further evaluation with greater studies of impact or review.

Four hundred and thirty four twins occurring in 220 women were studied during a period of 11 years (1969–1979) at Notre-Dame Hospital.Perinatal mortality (< 28 days) was compared before and after 1974, and the impact of ultrasound technique upon perinatal outcome was assessed during the second period (1974–1979). The main factor associated with perinatal mortality was low birth weight caused by either prematurity or intrauterine growth retardation.While fetal mortality remained unchanged within the two study periods, neonatal mortality decreased from 68.2/1,000 to 28.9/1,000 mainly due to increased survival rate of twins below 1,500 g at birth.With identical perinatal care during the same period, perinatal mortality and incidence of intrauterine growth-retarded twins remained unchanged despite early diagnosis by ultrasound.

Abstract Study question This cross-sectional survey sought the views of women seeking fertility treatment on the impact of the COVID–19 pandemic on their fertility treatment and attitudes. Summary answer Most respondents worried the recommendations to postpone treatment would reduce their chances of pregnancy and were concerned about negative effects of SARS-Cov–2 infections on pregnancy. What is known already In spring 2020, the recommendations of ESHRE and German professional societies to postpone fertility treatments resulted in limited or closed services from mid-March to early May in many clinics. Previous studies reported that postponing fertility clinic appointments causes psychological distress, with most patients saying they would have preferred to continue treatment. While no similar studies are available from Germany, where COVID–19 incidence was relatively low, concerns of the patients about possible consequences of a treatment delay and a SARS-CoV–2 infection on fertility and pregnancy remain unknown. Study design, size, duration This cross-sectional, anonymous, online questionnaire was completed in June-December 2020 by 249 women attending fertility clinics across Germany. The women were recruited using leaflets, directly by study personnel either in person or by telephone, or via online support group forums for fertility patients. Participants/materials, setting, methods All women seeking treatment in fertility clinics were eligible to participate. The online survey covered questions about the patient’s quality of life, their opinions about the professional societies’ recommendations and their effects as well as any concerns about infection with SARS-CoV–2. Statistical analysis was conducted using SPSS Version 27. Main results and the role of chance Three-quarters of participants disagreed with the pausing of fertility treatments. Women who participated from October-December 2020, when the incidence rate was high, were as likely to disagree as participants that participated from June-September 2020 (73% vs 79%, p = 0.3). Nearly all participants (95%) were concerned that treatment delays would reduce their chances of pregnancy. 72 participants (29%) had their appointments cancelled. Nearly all (97%) reported being upset by this, with 40 (56%) reporting that they were extremely or very disappointed about the cancellation. Women coming for follow-up appointments and women who had to wait 10 weeks or longer were more likely to be upset by the postponement or cancellation of their appointment (p = 0.016 and p = 0.012, respectively). Nearly all (97%) of the participants were worried about possible negative effects a SARS-CoV–2 infection might have related to their fertility, pregnancy or unborn child. Sixty-one percent stated they were very or moderately concerned about the negative influence the infection might have on the womańs own health during pregnancy and 60% were very to moderately concerned about potential negative effects for the unborn child. However, only 26% reported they were very or moderately concerned about the potential negative effects of an infection on fertility. Limitations, reasons for caution The main limitations of this study are the possibility of selection bias as people with strong opinions are more likely to have participated and the lack of information on non-responders due to the study design. Also, the Covid–19 pandemic is evolving continuously meaning that participantś opinions may vary over time. Wider implications of the findings: Postponement of treatments increased distress among patients and should be avoided when possible. If unavoidable, follow-up patients should be prioritised for treatment and the length of postponement should be minimised. Fertility clinics must provide information about the current state of knowledge of SARS-Cov–2 infections in pregnancies and options for immunization. Trial registration number Not applicable

Abstract Introduction Our study aims to evaluate the perinatal outcomes in twin pregnancies diagnosed with intrahepatic cholestasis of pregnancy (ICP) and to compare these with normal healthy twin pregnancies for perinatal outcomes. The second outcome of the study was to determine whether in vitro fertilization-embryo transfer (IVF-ET) affects the perinatal outcome in ICP patients. Materials and Methods In this study, 59 ICP and 641 healthy twin pregnancies were compared for perinatal outcomes retrospectively. According to the mode of conception, the twin pregnancies with ICP were divided into 2 groups. The twin pregnancies with ICP who were conceived with IVF were referred to as the IVF-ET group. The twin pregnancies with ICP who were conceived spontaneously or by ovulation induction and intrauterine insemination (IUI) were referred to as the non-IVF-ET group. Results Twin pregnancies with ICP give birth significantly earlier than normal twin pregnancies (p ˂ 0.001). The diagnosis of ICP occurred significantly earlier in the IVF-ET pregnancy with ICP than in the non-IVF-ET group. In twin pregnancies with IVF-ET, patients delivered significantly earlier than in the non-IVF-ET group (p=0.002). Twin pregnancies with ICP were found to have significantly higher rates of meconium-stained amniotic fluid, postnatal intubation, and admission to the neonatal intensive care unit (NICU) than healthy twin pregnancies. Conclusions ICP is a risk factor for preterm delivery in twin pregnancies. In addition, ICP develops earlier and more frequently in twin pregnancies from IVF-ET than in those from non-IVF twin pregnancies, and the disease may be more serious.

Ovine GH (oGH) is synthesized in placental tissue during maximal placental growth and development. Our objectives were to localize oGH mRNA in the placenta, and study the impact of exogenous GH on twin pregnancies during the normal window (35–55 days of gestational age; dGA) of placental expression. In situ hybridization localized oGH mRNA in uterine luminal epithelium but not in tissues of fetal origin. While maternal GH and IGF-I concentrations were increased (P<0.001) approximately tenfold, uterine, uterine fluid, placental, and fetal weights were unaffected by treatment at either 55 or 135 dGA. Fetal length, liver weight, and liver weight per kg of body weight were unaffected by maternal GH treatment. However, in the cotyledon, IGF-binding protein (BP)-1 and IGFBP-4 mRNA concentrations were increased (P<0.05), while IGFBP-2 mRNA was decreased (P<0.05). The concentration of mRNA for IGFBP-3 was unaffected by treatment. Within the caruncle, IGFBP-1 mRNA was decreased (P<0.05), while IGFBP-3 and IGFBP-4 mRNA were increased (P<0.05), and IGFBP-2 mRNA was unchanged due to GH treatment. While our data indicate that elevated maternal GH and IGF-I concentrations during early and mid-gestation do not enhance placental and fetal growth in twin pregnancies, localization of GH mRNA in uterine luminal epithelium could explain GHs transitory expression from 35 to 55 dGA, since by the end of this period the majority of the uterine luminal epithelium has fused with chorionic binucleate cells forming the placental syncytium.
