Abstract
Preterm birth remains the leading cause of mortality among under-5's and is a major contributor to the reduction in quality-of-life adjusted years and reduction in human capital. Globally, there are many interventions and care bundles that aim to reduce the impact of preterm birth once preterm labor has ensued and into the neonatal period; not all of these are applicable in all settings. Here, we introduce the FIGO PremPrep-5 initiative, which aims to disseminate key information on the most simple and effective interventions with the aim of increasing implementation globally. Before delivery, we recommend a course of antenatal corticosteroids, and intrapartum magnesium sulfate. At delivery, we recommend delayed cord clamping. Postnatally, we recommend early feeding with breast milk and immediate kangaroo care. While there are many other interventions that may improve outcomes at the time of labor and after preterm birth, these are clinically effective and relatively inexpensive options that can be practiced in most settings and supplemented with more advanced care. We include examples of a training video and infographics that will be used for dissemination.

BMC Pregnancy Childbirth 2024; 24:248. [PMID: 38589786 PMCID: PMC11000397 DOI: 10.1186/s12884-024-06427-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 03/14/2024] [Indexed: 04/10/2024] Open
Abstract
BACKGROUND Placental management strategies such as umbilical cord milking and delayed cord clamping may provide a range of benefits for the newborn. The aim of this review was to assess the effectiveness of umbilical cord milking and delayed cord clamping for the prevention of neonatal hypoglycaemia. METHODS Three databases and five clinical trial registries were systematically reviewed to identify randomised controlled trials comparing umbilical cord milking or delayed cord clamping with control in term and preterm infants. The primary outcome was neonatal hypoglycaemia (study defined). Two independent reviewers conducted screening, data extraction and quality assessment. Quality of the included studies was assessed using the Cochrane Risk of Bias tool (RoB-2). Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Meta-analysis using a random effect model was done using Review Manager 5.4. The review was registered prospectively on PROSPERO (CRD42022356553). RESULTS Data from 71 studies and 14 268 infants were included in this review; 22 (2 537 infants) compared umbilical cord milking with control, and 50 studies (11 731 infants) compared delayed with early cord clamping. For umbilical cord milking there were no data on neonatal hypoglycaemia, and no differences between groups for any of the secondary outcomes. We found no evidence that delayed cord clamping reduced the incidence of hypoglycaemia (6 studies, 444 infants, RR = 0.87, CI: 0.58 to 1.30, p = 0.49, I2 = 0%). Delayed cord clamping was associated with a 27% reduction in neonatal mortality (15 studies, 3 041 infants, RR = 0.73, CI: 0.55 to 0.98, p = 0.03, I2 = 0%). We found no evidence for the effect of delayed cord clamping for any of the other outcomes. The certainty of evidence was low for all outcomes. CONCLUSION We found no data for the effectiveness of umbilical cord milking on neonatal hypoglycaemia, and no evidence that delayed cord clamping reduced the incidence of hypoglycaemia, but the certainty of the evidence was low.

Abstract
BACKGROUND Placental cord drainage (PCD) after vaginal birth accelerates placental delivery by 2.85 minutes, but reduces blood loss by only 77 mL. AIMS To determine if PCD at elective caesarean section accelerates placental delivery, compared to delayed cord clamping (DCC). MATERIALS AND METHODS This randomised controlled trial randomised 100 women undergoing elective caesarean sections to receive either PCD for 60 sec after birth, or DCC for 60 sec. The primary outcome was time from birth until placental delivery. Secondary outcomes included estimated blood loss (EBL), postoperative haemoglobin drop, rates of postpartum haemorrhage (PPH), manual removal of placenta and blood transfusion. RESULTS There was no significant difference in timing of placental delivery (PCD 122 sec vs DCC 123.5 sec, P = 0.717). There were no significant differences in EBL (PCD 425 mL vs DCC 400 mL, P = 0.858), postoperative haemoglobin drop (PCD 12 g/L vs DCC 15 g/L, P = 0.297), PPH rate (PCD 45.8% vs DCC 44.4%, P = 0.893, relative risk (RR) 1.03, 95% confidence interval (CI) 0.66-1.62), manual removal rate (PCD 2.1% vs DCC 4.4%, P = 0.609, RR 0.47, 95% CI 0.04-4.99) or transfusion rate (PCD 4.2% vs DCC 0%, P = 0.495). CONCLUSIONS PCD did not accelerate placental delivery at caesarean compared with DCC. Given that both PCD and DCC groups had faster placental deliveries than quoted in the literature at caesarean (200 sec), it could be postulated that DCC is mimicking the effect of PCD through passive transfusion to the neonate. This supports routine use of DCC at elective caesarean section.

PLoS One 2024; 19:e0295929. [PMID: 38165946 PMCID: PMC10760750 DOI: 10.1371/journal.pone.0295929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 12/01/2023] [Indexed: 01/04/2024] Open
Abstract
BACKGROUND Delayed cord clamping (DCC) is a proven beneficial intervention, but the suggested timings of DCC vary from 30 to 300 seconds after birth or until cord pulsation stops. This study aimed to find the optimum timing of DCC to maximize the benefits such as an increase in hemoglobin, and hematocrit without increasing the risks of polycythemia and hyperbilirubinemia. METHODS We conducted a single-center prospective observational cohort study. All singleton neonates with gestational age ≥ 28 weeks born at the center in the 17 months of the study period from November 2020 to March 2022 were enrolled. Participants were divided into four groups based on DCC time: group A: <60 sec, group B: 60-119 sec, group C: 120-180 sec, and group D: >180 sec. The primary outcome was the levels of hemoglobin, hematocrit, and bilirubin at 48 hours of life. RESULTS Four hundred and eight neonates were enrolled. They were divided into four groups based on the timing of DCC (group A: n = 52, group B: n = 137, group C: n = 155, group D: n = 64). With an increase in the duration of DCC, there was an increase in the level of hemoglobin and hematocrit without an increase in the risk of polycythemia or neonatal hyperbilirubinemia. The benefits were best in group C (120-180 sec) and group D (>180 sec). CONCLUSIONS DCC of ≥ 120 seconds appears to be optimal where hemoglobin and hematocrit are highest without an increase in the risk of neonatal hyperbilirubinemia. The risk of adverse effects like polycythemia or neonatal hyperbilirubinemia requiring phototherapy did not increase even after extending the time of cord clamping to >180 seconds.

Abstract
OBJECTIVE This narrative review was performed to evaluate the correct timing of umbilical cord clamping for term infants. It was intended to determine any advantages or disadvantages from early or delayed cord clamping for newborns, infants or mothers. METHODS A systematic search on two databases was conducted using the PICO pattern to define a wide search. Out of 43 trials, 12 were included in this review. Three of the included studies are meta-analyses, nine are randomized controlled trials. RESULTS Early or delayed cord clamping was defined differently in all the included trials. However, there are many advantages from delayed cord clamping of at least > 60 s for newborns and infants up to 12 months of age. The trials showed no disadvantages for newborns or mothers from delayed cord clamping, except for a lightly increased risk of jaundice or the need for phototherapy. CONCLUSION Delayed umbilical cord clamping for term infants should be performed. Further research is needed to improve knowledge on physiological timing of umbilical cord clamping in term infants, which also leads to the same advantages as delayed cord clamping.

Socioeconomic and education-based inequality in suspected developmental delays among Nepalese children: a subnational level assessment. Sci Rep 2023; 13:4750. [PMID: 36959346 PMCID: PMC10036624 DOI: 10.1038/s41598-023-31629-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Accepted: 03/15/2023] [Indexed: 03/25/2023] Open
Abstract
Failure to meet early childhood developmental milestones leads to difficulty in schooling and social functioning. Evidence on the inequality in the burden of developmental delays across population groups, and identification of potential risk factors for suspected developmental delays (SDD) among younger children, are essential for designing appropriate policies and programs. This study explored the level of socioeconomic and maternal education-based inequality in the prevalence of SDD among Nepalese children at subnational level and identified potential risk factors. Individual-level data from the 2019 Nepal Multiple Indicator Cluster Survey was used to estimate the prevalence of SDD among children aged 3-4 years. Regression-based slope index of inequality (SII) and relative index of inequality were used to measure the magnitude of inequality, in terms of household socioeconomic status (SES) and mother's education, in the prevalence of SDD. In addition, a multilevel logistic regression model was used to identify potential risk factors for SDD. The national prevalence of SDD was found to be 34.8%, with relatively higher prevalence among children from rural areas (40.0%) and those from Karnali Province (45.0%) followed by Madhesh province (44.2%), and Sudhurpashchim Province (40.1%). The prevalence of SDD was 32 percentage points higher (SII: -0.32) among children from the poorest households compared to their rich counterparts at the national level. At the subnational level, such inequality was found to be highest in Lumbini Province (SII = -0.47) followed by Karnali Province (SII = -0.37), and Bagmati Province (SII = -0.37). The prevalence of SDD was 36 percentage points higher (SII: -0.36) among children whose mother had no formal education compared to children of higher educated mothers. The magnitude of education-based absolute inequality in SDD was highest in Lumbini Province (SII = -0.44). Multilevel logistic regression model identified lower levels of mother's education, disadvantaged SES and childhood stunting as significant risk factors for SDD. One in each three children in Nepal may experience SDD, with relatively higher prevalence among children from rural areas. Subnational level variation in prevalence, and socioeconomic and education-based inequality in SDD highlight the urgent need for province-specific tailored interventions to promote early childhood development in Nepal.
