The majority of early term elective cesarean sections can be postponed.

To access publisher's full text version of this article click on the hyperlink belowIntroduction: To minimize the risk of neonatal respiratory morbidity it is recommended that elective cesarean sections should not be done before 39-week gestation unless medically indicated. However, elective cesarean sections are still being performed at early term (at 370-386 weeks gestation) without sound medical indications. In this study, we evaluated the indications for elective cesarean sections performed at early term to assess the proportion of procedures that could possibly have been postponed until ≥39 weeks to avoid neonatal respiratory morbidity.Material and methods: Maternal and neonatal information was collected from medical records on all elective cesarean sections performed in singleton pregnancies at ≥370 weeks gestation over a 20-year period in a population with secure ultrasound gestational age assignment. Indications were grouped and uterine scar, breech, or transverse presentation and maternal request classified as nonurgent.Results: There were 3411 elective cesarean sections performed at ≥37-week gestation, of which 790 (23.2%) were at 370-386 weeks. Medical indications were present for 34% (272/790), but 65.6% (518/790) could possibly have been postponed until ≥390 weeks. Of the neonates 5.7% developed respiratory morbidity if delivery was at 370-386 weeks gestation compared to 2.4% at 390-421 weeks gestation (p < .001).Conclusion: Of elective cesarean sections before 39-week gestation two-thirds were done without a clear medical indication, thereby exposing the newborn to an increased risk of respiratory morbidity. Scheduling elective cesarean sections at ≥39-week gestation is important to minimize the risk of neonatal respiratory morbidity, unless a clear medical indication dictates earlier delivery.Landspitali University Hospital Research Fun

The potential for organ donation in Iceland: A nationwide study of deaths in intensive care units.

To access publisher's full text version of this article click on the hyperlink belowBackground: The deceased organ donation rate in Iceland has been low compared with other Western countries. The aim of this study was to explore the potential for organ donation after brain death in Iceland. Methods: Observational cohort study of patients with catastrophic brain injury who died in intensive care units (ICUs) at hospitals in Iceland in 2003-2016. Medical records were retrospectively reviewed to identify potential donors (PDs), using the WHO Critical Pathway for Deceased Donation. Trends in annual incidence of PDs, conversion to actual donors, and family refusals were assessed. Results: Among 1537 patients who died in the ICU, 125 (8.1%) were identified as PDs. Of 103 PDs who were declared brain dead, consent for organ donation was pursued in 84 cases and granted in 63. Fifty-six became actual donors. The annual donation rate averaged 13 per million population (pmp), but rose abruptly in the final 2 years to 36 and 27 pmp, respectively. This was paralleled by an increase in annual incidence of PDs from an average of 28 pmp to 54 and 42 pmp, respectively. The donor conversion rate increased during the study period (P = .026). Twenty-three PDs (18%) were not pursued without an apparent reason. Conclusions: The donation rate increased markedly in the last 2 years of the study period after remaining low for more than a decade. This change can largely be explained by a high incidence of PDs and a low family refusal rate. Missed donation opportunities suggest a potential to maintain a high donation rate in the future.Landspitali University Hospital Research Fun

Children may need higher vancomycin doses to achieve therapeutic levels.

To access publisher's full text version of this article click on the hyperlink belowAim: Vancomycin is frequently used in paediatric hospitals. Data suggest trough levels of 10-20 mg/L are needed to achieve bacterial killing. This study aimed to evaluate if commonly used dosing regimens are efficient in reaching these levels and if therapeutic drug monitoring (TDM) was appropriately used. Methods: All children receiving intravenous vancomycin at the Children´s Hospital Iceland between 2012 and 2016 were included. Vancomycin trough levels were registered. Student t test, Wilcoxon test and regression models were used for statistical analysis. Results: A total of 105 children received 163 vancomycin treatments (55/105 neonates). Average daily dose in neonates was 23.4 mg/kg/day and 38.4 mg/kg/day for older children. No TDM was done in 58 treatments (35.6%). First trough levels were <10mg/L in 52.4% and <15mg/L in 92% of cases. Therapeutic levels were less likely achieved in children with malignancy (11.8%) compared with others (36.8%, p = 0.09). Conclusions: In more than half of the cases, trough drug levels were <10 mg/L and malignancy was associated with the lowest probability of reaching therapeutic levels. This study suggests that starting doses of vancomycin in children should be higher, especially in relation to malignant diseases and supports the importance of antibiotic stewardship to ensure optimal antibiotic use.

Breastfeeding progression in late preterm infants from birth to one month.

This study aimed to describe and compare breastfeeding progression, infants' feeding behaviours, maternal feeding difficulties, and mothers' usage of breastfeeding interventions for singleton late preterm (LPT) and term infants. A further aim was to identify associated factors for exclusive breastfeeding at breast at 1 month in LPT infants. This was a cohort study where mothers of LPT infants from a neonatal unit (n = 60), LPT infants from a maternity unit (n = 62), and term infants from a maternity unit (n = 269) answered a questionnaire approximately 1 month after delivery. Findings showed no significant differences in exclusive breastfeeding at breasts between LPT infants admitted to the neonatal unit compared with the maternity unit, during the first week at home (38% vs. 48%), or at 1 month of age (52% vs. 50%). Term infants were more likely to be exclusively breastfed at the breast (86% and 74%, p &lt; 0.05) compared with LPT infants. Multiple regression analysis showed that usage of a nipple shield, not feeding breast milk exclusively during the first week at home, or feeding less than 10 times per day at 1 month were statistically significant for not exclusively breastfeed at the breast. A protective factor was the mothers' experience of having an abundance of milk during the first week at home. In conclusion, LPT infants are less likely to be exclusively breastfed at the breast than term infants, highlighting the need for further research to guide interventions aimed at optimising exclusive breastfeeding rates

Please click on the hyperlink in Additional Links field.To examine survival and outcome of extremely low-birth-weight (ELBW) children (birth weight < 1000 g) in two 5-year periods, 10 years apart. In a retrospective population-based study, information on all ELBW children born in Iceland in 1991-1995 and in 2001-2005 was obtained from the National Birth Registry, hospital charts and medical records. The two periods were compared. In 1991-1995, 102 of 22.261 newborn children (0.5%) were extremely low birth weight compared with 70 of 20.923 newborns (0.33%) in 2001-2005 (p = 0.04). At 5 years of age, 52% (35/67) of live-born children born in 1991-1995 were alive compared with 63% (31/49) of children born in 2001 - 2005 (p = 0.2). Six ELBW children (17%) born 1991-1995 were diagnosed with disabilities at 5 years of age, three with major neurodevelopmental disabilities compared with six (19%) born 2001-2005, thereof one with severe neurodevelopmental disabilities (p = 0.57). The incidence of childhood disabilities in ELBW children in Iceland remains stable despite an increase in survival rate. The severity of neurodevelopmental disabilities has decreased

Cesarean birth, obstetric emergencies, and adverse neonatal outcomes in Iceland during a period of increasing labor induction.

To access publisher's full text version of this article click on the hyperlink belowBackground: The rate of labor induction has risen steeply throughout the world. This project aimed to estimate changes in the rates of adverse maternal and neonatal outcomes in Iceland between 1997 and 2018, and to assess whether the changes can be explained by an increased rate of labor induction. Methods: Singleton live births, occurring between 1997 and 2018, that did not start by prelabor cesarean, were identified from the Icelandic Medical Birth Register (n = 85 971). Rates of intrapartum cesarean birth (CB), obstetric emergencies, and neonatal outcomes were calculated, and adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) were estimated with log-binomial regression (reference: 1997-2001). Adjustments were made for: (a) maternal characteristics, and (b) labor induction and gestational age. Results: The rate of labor induction increased from 13.6% in the period 1997-2001 to 28.1% in the period 2014-2018. The rate of intrapartum CB decreased between the periods of 1997-2001 and 2014-2018 for both primiparous (aRR 0.76, 95% CI: 0.69 to 0.84) and multiparous women (aRR 0.55, 95% CI: 0.49 to 0.63). The rate of obstetric emergencies and adverse neonatal outcomes also decreased between these time periods. Adjusting for labor induction did not attenuate these associations. Conclusions: The rates of adverse maternal outcomes and adverse neonatal outcomes decreased over the study period. However, there was no evidence that this decrease could be explained by the increased rate of labor induction.

The effects of smoking in pregnancy on factors influencing fetal growth

To access Publisher full text version of this article. Please click on the hyperlink in Additional Links fieldAIM: To evaluate the influence of maternal smoking during pregnancy on factors influencing fetal growth. METHODS: Thirty newborns of smoking mothers were prospectively compared with 60 newborns of non-smoking mothers. Pre-albumin, albumin, triglycerides, glucose, insulin, insulin-like growth factor I, IGF binding protein 3, pH, lactic acid, erythropoietin and hemoglobin concentrations were measured in umbilical cord blood. RESULTS: Infants of smoking mothers had a significantly lower birth weight (3418 +/- 533 vs. 3863 +/- 503 g; p < 0.001), length (50.5 +/- 2,6 vs. 52.3 +/- 1.9 cm; p < 0.001) and head circumference (34.6 +/- 1.8 vs. 35.8 +/- 1.1 cm; p < 0.001) than controls. They also had significantly lower insulin (3.2 (2.0-4.9) vs. 5.8 (4.6-7.1) mU/L; p = 0.008), insulin-like growth factor I (54.4 +/- 32.5 vs. 93.8 +/- 54.5 microg/L; p = 0.001) and IGF binding protein 3 (1664 +/- 432 vs. 1943 +/- 421 microg/L; p = 0.01) concentrations, than controls. Infants of smoking mothers also had significantly higher hemoglobin (167 +/- 14 vs. 157 +/- 13 g/L; p = 0.002) and erythropoietin (42.3 (25.1-72.4) vs. 26.3 (21.9-30.9) U/L; p = 0.03) than controls, but not pH or lactate concentrations. There was no significant difference in pre-albumin, albumin, triglycerides and glucose concentrations. CONCLUSIONS: Smoking during pregnancy causes symmetrical fetal growth impairment, possibly due to decreased oxygen transport to the fetus and decreased concentrations of fetal insulin, insulin-like growth factor I and IGF binding protein 3

Group B streptococcal infections in infants in Iceland: clinical and microbiological factors.

To access publisher's full text version of this article, please click on the hyperlink in Additional Links field or click on the hyperlink at the top of the page marked DownloadIntroduction. Group B streptococcus (GBS) is a leading cause of invasive neonatal infections. These have been divided into early-onset disease (EOD; <7 days) and late-onset disease (LOD; 7-89 days), with different GBS clonal complexes (CCs) associated with different disease presentations.Hypothesis. Different GBS CCs are associated with timing of infection (EOD or LOD) and clinical presentation (sepsis, meningitis or pneumonia).Aim. To study infant GBS infections in Iceland from 1975 to 2019. Are specific GBS CCs related to disease presentation? Is CC17 overrepresented in infant GBS infections in Iceland?Methodology. All culture-confirmed invasive GBS infections in infants (<90 days) in Iceland from 1975 to 2019 were included. Clinical information was gathered from medical records.Results. A total of 127 invasive GBS infections in infants were diagnosed, but 105 infants were included in the study. Of these, 56 had EOD and 49 had LOD. The incidence of GBS infections declined from 2000 onwards but increased again at the end of the study period. Furthermore, there was a significant increase in LOD over the study period (P=0.0001). The most common presenting symptoms were respiratory difficulties and fever and the most common presentation was sepsis alone. Approximately one-third of the cases were caused by GBS CC17 of serotype III with surface protein RIB and pili PI-1+PI-2b or PI-2b. CC17 was significantly associated with LOD (P<0.001).Conclusion. CC17 is a major cause of GBS infection in infants in Iceland. This clone is associated with LOD, which has been increasing in incidence. Because intrapartum antibiotic prophylaxis only prevents EOD, it is important to continue the development of a GBS vaccine in order to prevent LOD infections.Landspitali-University Hospital of Icelan
