- PURPOSE: The purpose of this study is to investigate placental ghrelin and leptin expression as well as cord blood ghrelin and adiponectin levels in maternal obesity and associations between placental ghrelin expression, cord blood ghrelin levels and maternal and infant variables.MATERIALS AND METHODS: Placental ghrelin and leptin expression were analyzed by RT-PCR in 32 severely obese and 32 matched normal-weight women. Cord blood ghrelin, adiponectin, leptin, and C-peptide concentrations were analyzed by ELISA.RESULTS: Neither ghrelin nor leptin expression and neither cord blood ghrelin nor adiponectin levels differed between the groups. Placental ghrelin expression was associated with BMI at delivery in the obese women (r = 0.424, p = .016) and in the infants born to normal-weight women with their weight z-scores at six (r = -0.642, p = .010), nine (r = -0.441, p = .015), and 12 months of age (r = -0.402, p = .028).CONCLUSIONS: Placental ghrelin and leptin expression as well as cord blood ghrelin and adiponectin levels do not seem to be altered in severe maternal obesity. Placenta-derived ghrelin may influence the infants' postnatal weight gain, but possibly only when the mother has normal weight.

- Boys born small for gestational age (SGA) are at increased risk of testicular dysgenesis syndrome, and girls born SGA face the risk of polycystic ovary syndrome later in life. Our aim was to study whether neonates born SGA have an altered profile of steroid hormones at birth.A total of 168 singletons (99 boys, 69 girls) born at 32.0-36.9 gestational weeks were recruited to a population-based, university hospital, single-center study. Of these, 31 infants (17 boys, 14 girls) were born SGA. The concentrations of dehydroepiandrosterone sulfate (DHEAS), androstenedione, testosterone, dihydrotestosterone, estrone, estradiol, cortisone, and cortisol were analyzed in umbilical cord serum with mass spectrometry.Girls born SGA had higher levels of androstenedione than girls born appropriate for gestational age (AGA) (4.0 versus 2.6nmol/L, p = 0.002). Boys born SGA had lower levels of estrone than boys born AGA (33822 versus 62471pmol/L, p = 0.038). Infants born SGA had lower levels of cortisone than infants born AGA, both in girls (340 versus 579nmol/L, p = 0.010) and in boys (308 versus 521nmol/L, p = 0.045). Furthermore, boys born SGA had a higher cortisol/cortisone ratio than boys born AGA (0.41 versus 0.25, p = 0.028). Gestational age correlated with DHEAS (boys r = 0.48, p = 0.000, girls r = 0.35, p = 0.013), and cortisol (boys r = 0.48, p = 0.000, girls r = 0.29, p = 0.039).In moderate-to-late preterm infants born SGA we observed a different steroid hormone profile in cord serum. Girls born SGA show increased levels of androstenedione and boys born SGA show decreased levels of estrone in cord serum, which could be related to placental aromatase deficiency in intrauterine growth restriction.

- Objective. The purpose of this experimental study was to elucidate alterations in fetal energy metabolism in relation to ECG changes during extreme fetal asphyxia, postnatal resuscitation and the immediate post-resuscitatory phase. Study design. Five near-term fetal sheep were subjected to umbilical cord occlusion until cardiac arrest followed by delivery, resuscitation and postnatal pressure-controlled ventilation. Four sheep served as sham controls and were delivered immediately after ligation of the umbilical cord. Fetal ECG was analysed online for changes of the ST segment. Fetal metabolism was monitored by intracerebral and subcutaneous microdialysis catheters. Results. Fetal ECG reacted on cord occlusion with an increase in the T-wave height followed by changes in intracerebral levels of oxidative parameters. Cerebral lactate/pyruvate ratio and glutamate increased to median (range) of 240 (200-744) and 34.0 (22.6-60.5) mmol/l, respectively; both parameters returned to baseline after resuscitation. Cerebral glucose decreased to 0.1 (0.08-0.12) mmol/l after occlusion and increased above baseline upon resuscitation. In subcutaneous tissue as well as blood the increase in lactate occurred with a delay compared to cerebral levels. Conclusion. The fetal ECG changes related to asphyxia preceded the increase in excitotoxicity as determined by increase in cerebral glutamate during asphyxia. Cerebral lactate increase was superior to subcutaneous lactate increase.

- AIM: The primary objective was to describe the incidence, symptoms, clinical signs, and time of onset of neonatal pneumothorax in Örebro County during 2011-2017. Secondary objectives were to describe risk factors, diagnostic procedures, treatments, and mortality and to compare preterm with term/post-term neonates.MATERIALS AND METHODS: This retrospective population-based descriptive study included all neonates born in Örebro County during 2011-2017 and admitted to the neonatal intensive care unit at Örebro University Hospital at age <28 days with an x-ray verified diagnosis of "Pneumothorax originating in the perinatal period" in their medical record.RESULTS: Seventy-five neonates matched the inclusion criteria. The incidence of neonatal pneumothorax in Örebro County during the study period was 3.1 (95% CI: 2.5-3.8) per 1000 live births. All neonates were <48 h at debut of respiratory symptoms and the most common symptom was tachypnea. Twelve (16%) received invasive treatment. The mortality rate was 2 (3%), none due to pneumothorax.CONCLUSION: The incidence of 3.1 per 1000 live births was relatively high, but the frequency of invasive treatment and mortality was low, indicating a high proportion of mild pneumothoraces. The lack of patients aged >48 h indicates that most neonatal pneumothoraces now occur very early in life.

- The study aimed to determine the cervical calreticulin and cathepsin-G concentrations in pregnancies complicated by preterm prelabor rupture of membranes (PPROM) with respect to the presence of microbial invasion of the amniotic cavity (MIAC) and intra-amniotic inflammation (IAI).Eighty women with singleton pregnancies complicated by PPROM were included in this study. Cervical and amniotic fluids were obtained at the time of admission, and concentrations of calreticulin and cathepsin-G in cervical fluid were determined using ELISA. The MIAC was defined as a positive PCR analysis for Ureaplasma species, Mycoplasma hominis, and/or Chlamydia trachomatis and/or by positivity for the 16S rRNA gene. IAI was defined as amniotic fluid bedside IL-6 concentrations ≥745pg/mL Result: Neither women with MIAC nor with IAI had different cervical fluid concentrations of calreticulin (with MIAC: median 18.9pg/mL vs. without MIAC: median 14.7pg/mL, p=0.28; with IAI: median 14.3pg/mL vs. without IAI: median 15.6pg/mL, p=0.57;) or of cathepsin-G (with MIAC: median 30.7pg/mL vs. without MIAC: median 24.7pg/mL, p=0.28; with IAI: median 27.3pg/mL vs. without IAI: median 25.1pg/mL, p=0.80) than women without those complications. No associations between amniotic fluid IL-6 concentrations, gestational age at sampling, and cervical fluid calreticulin and cathepsin-G concentrations were found.Cervical fluid calreticulin and cathepsin-G concentrations did not reflect the presence of MIAC or IAI in women with PPROM.

Ingår i: The Journal of Maternal-Fetal & Neonatal Medicine. - : Informa UK Limited. - 1476-7058 .- 1476-4954. ; 27:14, s. 1502-1506

Forskningsöversikt (refereegranskat)abstract
- Muenke is a fibroblast growth factor receptor 3 (FGFR-3)-associated syndrome, which was first described in late 1990s. Muenke syndrome is an autosomal dominant disorder characterized mainly by coronal suture craniosynostosis, hearing impairment and intellectual disability. The syndrome is defined molecularly by a unique point mutation c.749C>G in exon 7 of the FGFR3 gene which results to an amino acid substitution p. Pro250Arg of the protein product. Despite the fact that the mutation rate at this nucleotide is one of the most frequently described in human genome, few Muenke familial case reports are published in current literature. We describe individuals among three generations of a Greek family who are carriers of the same mutation. Medical record and physical examination of family members present a wide spectrum of clinical manifestations. In particular, a 38-year-old woman and her father appear milder clinical findings regarding craniofacial characteristics compared to her uncle and newborn female child. This familial case illustrates the variable expressivity of Muenke syndrome in association with an identical gene mutation.

- Objective: The aim of the present study was to assess the impact of different maternal Body Mass Index (BMI) classes on the risk of postpartum endometritis, wound infection, and breast abscess after different modes of delivery. Secondly to estimate how the risk of postpartum infection varies with different maternal BMI groups after induction of labor and after obstetric anal sphincter injuries.Methods: A population-based observational study including women who gave birth during eight years (N = 841,780). Data were collected from three Swedish Medical Health Registers, the Swedish Medical Birth Register, the Swedish National Patient Register, and the Swedish Prescribed Drug Register. Outcomes were defined by ICD-10 codes given within eight weeks postpartum. The reference population was uninfected women. Odds ratios were determined using Mantel-Haenszel technique. Year of delivery, maternal age, parity and smoking in early pregnancy were considered as confounders.Results: There was a dose-dependent relationship between an increasing maternal BMI and a higher risk for postpartum infections. Women in obesity class II and III had an increased risk for endometritis after normal vaginal delivery aOR 1.45 (95% CI: 1.29-1.63) and for wound infections after cesarean section aOR 3.83 (95% CI: 3.39-4.32). There was no difference in how maternal BMI affected the association between cesarean section and wound infection, regardless of whether it was planned or emergent. Women in obesity class II and III had a lower risk of breast abscess compared with normal-weight women, aOR 0.47 (95% CI: 0.38-0.58). The risk of endometritis after labor induction decreased with increasing maternal BMI. The risk of wound infection among women with an obstetrical sphincter injury decreased with increasing BMI.Conclusion: This study provides new knowledge about the impact of maternal BMI on the risk of postpartum infections after different modes of delivery. There was no difference in how BMI affected the association between cesarean section and wound infections, regardless of whether it was a planned cesarean section or an emergency cesarean section.
