- Objective: To investigate the placental gene expression of substances in the inflammatory cascade and growth factors at nine different well-defined sampling sites in full-term placentas from 12 normal weight healthy non-smoking women with an uncomplicated singleton pregnancy.Methods: All placentas (six girls and six boys) were delivered vaginally. Quantitative real-time polymerase chain reaction was used to analyze toll receptor-2 and -4, interleukin-6 and -8, tumor necrosis factor-α, leptin, ghrelin, insulin-like growth factor-1 and -2, hepatocyte growth factor, hepatocyte growth factor receptor and insulin receptor (IR).Results: The leptin gene and the IR gene showed higher expression in lateral regions near the chorionic plate compared to central regions near the basal plate (P = 0.028 and P = 0.041, respectively).Conclusion: Our results suggest that the sampling site may influence the gene expression for leptin and IR in placental tissue obtained from full-term normal pregnancies. We speculate that this may be due to differences in placental structure and perfusion and may be important when future studies are designed.

- Objective: To survey the placental gene expression of inflammatory markers and growth factors in non-smoking obese women with an uncomplicated pregnancy without associated morbidity and delivery at term compared with normal weight women.Methods: Placental tissue samples from 32 obese women (body mass index, BMI >= 35.0 kg/m(2)) were compared with samples from 94 normal weight women (BMI 18.5-25.0 kg/m(2)) matched for age (+/- 1 year), gestational age (+/- 3 days), parity and mode of delivery. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) was used to analyse toll receptor-2 and -4, interleukin-6 and -8, tumour necrosis factor-alpha, leptin, adiponectin, insulin-like growth factor-1 and -2, hepatocyte growth factor, hepatocyte growth factor receptor and insulin receptor.Results: There was no significant difference in gene expression in placental tissue samples from obese and normal weight women.Conclusion: We found no difference in the occurrence of inflammatory marker and growth factor mRNA levels in placental tissue samples from a large group of obese women without associated morbidity and with healthy infants compared to a closely matched control group of healthy normal weight women. Compared with the previous studies, this anomalous finding may be explained by the absence of associated morbidity in the obese women in our study.

- The purpose was to evaluate the association between maternal characteristics, obstetrical interventions/complications and postpartum wound infections (WI), urinary tract infection (UTI) and endometritis. Furthermore, this study aimed to determine the time from delivery to onset of infections after discharge from the hospital. Three large Swedish Medical Health Registers were scrutinized for the period 2005-2012. A total of 582,576 women had 795,072 deliveries. Women with diagnosis codes for WIs, UTIs or endometritis, from delivery to 8 weeks postpartum, were compared to non-infected women. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated. Increasing age and body mass index (BMI) were both associated with increasing prevalence of postpartum infections. WIs were most strongly associated with cesarean section (CS) (OR 17.2; 95% CI 16.1-18.3), 3rd and 4th degree tears (OR 10.7%; 95% CI 9.80-11.9) and episiotomy (OR 10.2; 95% CI 8.94-11.5). Endometritis was associated with anemia (OR 3.16; 95% CI 3.01-3.31) and manual placental removal (OR 2.72; 95% CI 2.51-2.95). UTI was associated with emergency CS (OR 3.46; 95% CI 3.07-3.89) and instrumental delivery (OR 3.70; 95% CI 3.29-4.16). For women discharged from the delivery hospital the peak occurrence of UTI was 6 days postpartum, while for WIs and endometritis it was 7 days postpartum.

- Objective:Lactate ProStudy design:A cross-sectional study was conducted at a university hospital in Sweden. A total of 113 laboring women with fetal heart rate abnormalities on cardiotocography (CTG) had FBS carried out. Lactate concentration was measured bedside with both LP1 and LP2 from the same blood sample capillary. A linear regression model was constructed to retrieve a conversion equation to convert LP2 values to LP1 values.Results:LP2 measured higher values than LP1 in all analyses. We found that 4.2 mmol/L with LP1 corresponded to 6.4 mmol/L with LP2. Likewise, 4.8 mmol/L with LP1 corresponded to 7.3 mmol/L with LP2. The correlation between the analyses was excellent (Spearman’s rank correlation, r=0.97).Conclusion:We recommend the following guidelines when interpreting lactate concentration in FBS with LP2: <6.4 mmol/L to be interpreted as normal, 6.4–7.3 mmol/L as preacidemia indicating a follow-up FBS within 20–30 min, and >7.3 mmol/L as acidemia indicating intervention.

- BackgroundMetabolic acidosis, measured in arterial umbilical cord blood at birth, is the most accepted definition of birth asphyxia. The aim of the study was to investigate the rates of metabolic acidosis across the entire range of Apgar score values (0–10) at 1, 5, and 10 min in term infants.MethodsIn a population-based Swedish cohort of births between 2008 and 2013, we included 85,076 term (≥37 weeks) non-malformed infants with information from umbilical arterial blood gas analyses and complete information on Apgar scores (0–10) at 1, 5, and 10 min.ResultsRates of metabolic acidosis generally decreased with increasing Apgar score values. For Apgar score at 1 min, this decrease was consistent from Apgar score 0 (35%) to Apgar score 10 (0%). For Apgar scores at 5 and 10 min, the decrease was consistent for Apgar score values from 6 to 10.ConclusionAlthough there is a close association between Apgar score values and rates of metabolic acidosis, Apgar score is not and should not be used as a measure of birth asphyxia.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Fetal hypoxia and preterm delivery are reported to be strongly associated with brain damage and neurodevelopmental delay. Doppler signs of fetal brain sparing have been described during chronic hypoxia, but whether they are related to brain damage is unknown. The aim of this study was to evaluate if markers of tissue injury, i.e., tumor necrosis factor-alpha. (TNF-alpha) and interleukin-6 (IL-6) are related to signs of increased perinatal vascular impedance and/or fetal brain sparing in high-risk pregnancies. Study design: TNF-alpha and IL-6 levels were evaluated in maternal blood serum of 67 high-risk pregnancies. Serum samples were taken at the time of umbilical, middle cerebral artery and uterine artery Doppler velocimetry examination. The values for TNF-alpha and IL-6 were correlated with reference median values obtained with gestational age in the form of a Z-score. Results: TNF-alpha levels showed values within the normal range in only four cases. IL-6 values were found normal in 14 cases. The Z-score for mean middle cerebral artery pulsatility index (PI) showed a significant correlation to TNF-alpha and IL-6 levels, P < 0.0001 and P < 0.003, respectively. This might suggest a strong correlation between signs of fetal brain sparing and increased maternal serum TNF-alpha and IL-6 levels. Abnormal uterine artery PI and the presence of a "notch" were also highly significantly related to TNF-alpha and IL-6 levels, which were nearly two-fold higher compared to normal uterine artery blood flow and the absence of a "notch". Abnormal cerebro/placental ratios showed significant correlations to TNF-alpha and IL-6 levels. Conclusion: The present results suggest a strong correlation between levels of TNF-a and IL-6 not only for signs of fetal brain sparing, but also for uteroplacental blood flow. This finding supports the role of tissue injury in cases of fetal brain sparing, but whether this is a reflection of brain damage or secondary to placental pathology needs further evaluation.
