Aim: To investigate the impact of immediate skin‐to‐skin contact with a parent after birth on thermal regulation in very preterm infants.Methods: This clinical trial was conducted in three neonatal intensive care units in Scandinavia from 2018 to 2021. Infants born between 28 + 0 and 32 + 6 weeks and days of gestation were randomised to immediate skin‐to‐skin contact or conventional care in an incubator during the first 6 postnatal hours. We report on a secondary outcome: serial measurements of axillary temperature.Results: Ninety‐one infants were randomised to skin‐to‐skin contact or conventional care. Mean (range) gestational ages were 31 + 2 (28 + 6, 32 + 5) and 31 + 0 (28 + 4, 32 + 6) weeks and days, mean birth weights were 1572 (702, 2352) and 1495 (555, 2440) grams, respectively. Mean (95%CI, p‐value) temperatures were within the normal range in both groups, 0.2°C (−0.29, −0.14, p < 0.001) lower in the skin‐to‐skin contact group. The skin‐to‐skin contact group had a lower relative risk (95%CI, p‐value) of developing events of hyperthermia, RR = 0.70 (0.50, 0.99, p = 0.04).Conclusions: Very preterm infants, irrespective of clinical stability, do not develop hypothermia during immediate skin‐to‐skin contact after birth. Immediate skin‐to‐skin contact did protect against events of hyperthermia. Concerns about thermal regulation should not limit implementation of immediate skin‐to‐skin contact in high‐resource settings.

Objective: To compare the accuracy of heart rate detection properties of a novel, wireless, dry-electrode electrocardiogram (ECG) device, NeoBeat®, to that of a conventional 3-lead gel-electrode ECG monitor (PropaqM®) in newborns. Results: The study population had a mean gestational age of 39 weeks and 2 days (1.5 weeks) and birth weight 3528 g (668 g). There were 950 heart rate notations from each device, but heart rate was absent from the reference monitor in 14 of these data points, leaving 936 data pairs to compare. The mean (SD) difference when comparing NeoBeat to the reference monitor was -0.25 (9.91) beats per minute (bpm) (p = 0.44). There was a deviation of more than 10 bpm in 7.4% of the data pairs, which primarily (78%) was attributed to ECG signal disturbance, and secondly (22%) due to algorithm differences between the devices. Excluding these outliers, the correlation was equally consistent (r² = 0.96) in the full range of heart rate captured measurements with a mean difference of − 0.16 (3.09) bpm. The mean difference was less than 1 bpm regardless of whether outliers were included or not.

Klebsiella pneumoniae sequence type (ST) 17 is a global problem clone that causes multidrug-resistant (MDR) hospital infections worldwide. In 2008–2009, an outbreak of MDR ST17 occurred at a neonatal intensive care unit (NICU) in Stavanger, Norway. Fifty-seven children were colonized. We observed intestinal persistence of ST17 in all of the children for up to two years after hospital discharge. Here, we investigated the within–host evolution of ST17 in 45 of those children during long-term colonization and compared the outbreak with 254 global strains. Ninety-two outbreak-related isolates were whole-genome sequenced. They had capsule locus KL25, O locus O5 and carried yersiniabactin. During within–host colonization ST17 remained stable with few single nucleotide polymorphisms, no acquisition of antimicrobial resistance (AMR) or virulence determinants, and persistent carriage of a bla _CTX-M-15-encoding IncFII(K) IncFIB(K) plasmid (pKp2177_1). The global collection included ST17 from 1993 to 2020 from 34 countries, that were from human infection (41.3%), colonization (39.3%) and respiratory specimens (7.3%), from animals (9.3%), and from the environment (2.7%). We estimate that ST17 emerged mid-to-late 19th century (1859, 95 % HPD 1763–1939) and diversified through recombinations of the K and O loci to form several sublineages, with various AMR genes, virulence loci and plasmids. There was limited evidence of persistence of AMR genes in any of these lineages. A globally disseminated sublineage with KL25/O5 accounted for 52.7 % of the genomes. It included a monophyletic subclade that emerged in the mid-1980s, which comprised the Stavanger NICU outbreak and 10 genomes from three other countries, which all carried pKp2177_1. The plasmid was also observed in a KL155/OL101 subclade from the 2000s. Three clonal expansions of ST17 were identified; all were healthcare-associated and carried either yersiniabactin and/or pKp2177_1. To conclude, ST17 is globally disseminated and associated with opportunistic hospital-acquired infections. It contributes to the burden of global MDR infections, but many diverse lineages persist without acquired AMR. We hypothesize that non-human sources and human colonization may play a crucial role for severe infections in vulnerable patients, such as preterm neonates.

Positive pressure ventilation of the non-breathing newborn is a critical and time-sensitive intervention, considered to be the cornerstone of resuscitation. Many healthcare providers working in delivery units in high-resource settings have little opportunity to practise this skill in real life, affecting their performance when called upon to resuscitate a newborn. Low-dose, high-frequency simulation training has shown promise in low-resource settings, improving ventilation performance and changing practice in the clinical situation. We performed a randomised controlled study of low-dose, high-frequency simulation training for maintenance of ventilation competence in a multidisciplinary staff in a busy teaching hospital in Norway. We hypothesised that participants training according to a low-dose, high-frequency protocol would perform better than those training as they wished. Our results did not support this, although the majority of protocol participants were unable to achieve training targets. Subgroup analysis comparing no training to at least monthly training did identify a clear benefit to regular simulation practice. Simulated ventilation competence improved significantly for all participants over the course of the study. We conclude that frequent, short, simulation-based training can foster and maintain newborn ventilation skills in a multidisciplinary delivery unit staff in a high-resource setting.

Background: Assessment of heart rate (HR) is essential during newborn resuscitation, and comparison of dry-electrode ECG technology to standard monitoring by 3-lead ECG and Pulse Oximetry (PO) is lacking. Methods: NeoBeat, ECG, and PO were applied to newborns resuscitated at birth. Resuscitations were video recorded, and HR was registered every second. Results: Device placement time from birth was median (quartiles) 6 (4, 18) seconds for NeoBeat versus 138 (97, 181) seconds for ECG and 152 (103, 216) seconds for PO. Time to first HR presentation from birth was 22 (13, 45) seconds for NeoBeat versus 171 (129, 239) seconds for ECG and 270 (185, 357) seconds for PO. Proportion of time with HR feedback from NeoBeat during resuscitation from birth was 85 (69, 93)%, from arrival at the resuscitation table 98 (85, 100)%, and during positive pressure ventilation 100 (95, 100)%. For ECG, these proportions were, 25 (0, 43)%, 28 (0, 56)%, and 33 (0, 66)% and for PO, 0 (0, 16)%, 0 (0, 16)%, and 0 (0, 18)%. All p < 0.0001. Conclusions: NeoBeat was faster to place, presented HR more rapidly, and provided feedback on HR for a larger proportion of time during ongoing resuscitation compared to 3-lead ECG and PO.

Aim: The aim was to study the prevalence of bradycardia at birth in newborns requiring positive pressure ventilation (PPV), distribution of first measured heart rate (HR), changes in HR before start of PPV and HR response to PPV.Methods: A population‐based study including newborns ≥30 weeks' gestation receiving PPV at birth. HR was captured immediately after birth and continuously throughout resuscitation using the dry‐electrode ECG device NeoBeat. Time of birth was registered in the Liveborn app. Provision of PPV was captured by video.Results: We included 98 newborns receiving PPV at birth. Among newborns with HR measured within 60 s after birth, median (quartiles) first HR was 112 (84, 149) bpm recorded 19 (14, 37) s after birth, of which 33% had first HR <100 and 10% had first HR <60 bpm respectively. First HR was widely distributed. Median HR at start PPV 69 s after birth was 129 bpm. In newborns with an initial low HR, HR typically remained low for 20 s of PPV before increasing rapidly over the next 20–30 s.Conclusions: First measured HR was ≥100 bpm in two thirds of newborns receiving PPV. In bradycardic infants, HR did not increase until after 20 s of PPV.
