Smartphone apps hold promise for neonatal emergency care in low-resource settings.

AIM: Many countries risk failing the Sustainable Development Goal to reduce neonatal mortality to 12 in 1000 live births before 2030, necessitating intervention. This scoping review assesses available evidence from studies implementing smartphone application-based education and clinical decision support in neonatal emergency care in low- and middle-income countries and describes applied assessment tools to highlight gaps in the current literature. METHODS: A systematic search on 28 March 2024 of PubMed, Web of Science, and EMBASE identified original research papers published in peer-reviewed journals after 2014 in English. The evaluation was based on Kirkpatrick's framework. RESULTS: In total, 20 studies assessing eight different smartphone applications were included. Participants found applications acceptable and feasible in 11 of 14 studies. Knowledge and/or skills were improved in 11 of 12 studies. Behaviour was assessed in 10 studies by tracking app usage. Patient outcome was assessed in four studies, focusing on perinatal mortality, Basic Newborn Care outcomes and correct assessment of newborns. CONCLUSION: Data from included studies further strengthens hope that smartphone applications can improve neonatal mortality rates in low- and middle-income countries. However, further research into the effectiveness of these applications is warranted. This review highlights gaps in the current literature and provides guidance for future trials.

Decision and economic evaluation of abortion availability in the United States military.

BACKGROUND: Active-duty service women rely on the civilian sector for most abortion care due to limits on federal funding for abortion. Abortion is now banned in many states with large military presences. The Department of Defense has implemented policies to assist active-duty service women in accessing abortion, but there is debate to reverse this support. OBJECTIVE: Our goal was to compare the cost-effectiveness and incidence of adverse maternal and neonatal outcomes of a hypothetical cohort of active-duty service women living in abortion-restricted states comparing restricted abortion access (abortion not available cohort) to abortion available with Department of Defense travel support (abortion available cohort). STUDY DESIGN: We developed a decision tree model to compare abortion not available and abortion available cohorts for active-duty service women living in abortion-restricted states. Our cohorts were subdivided into normal pregnancies and those with a major fetal anomaly. Cost estimates, probabilities, and disability weights of various health conditions associated with abortion and pregnancy were obtained and derived from the literature. Effectiveness was expressed in disability-adjusted life years and the willingness to pay threshold was set to $100,000 per disability-adjusted life year gained or averted. We completed probabilistic sensitivity analyses with 10,000 simulations to test the robustness of our results. Secondary outcomes included numbers of stillbirths, neonatal deaths, neonatal intensive care unit admissions, maternal deaths, severe maternal morbidities, and first and second trimester abortions. RESULTS: The abortion not available cohort had a higher annual cost to the military ($299.1 million, 95% CI 239.2 - 386.6, vs. $226.0 million, 95% CI 181.9 - 288.5) and was associated with 203 more disability-adjusted life years compared to the abortion available cohort. The incremental cost effectiveness ratio was dominant for abortion available. Abortion not available resulted in an annual additional 7 stillbirths, 1 neonatal death, 112 neonatal intensive care unit admissions, 0.016 maternal deaths, 24 severe maternal morbidities, 27 less second trimester abortions, and 602 less first trimester abortions. Probabilistic sensitivity analysis revealed that the chance of the abortion available cohort being the more cost-effective strategy was greater than 95%. CONCLUSION: Limiting active-duty service women's access to abortion care increases costs to the military, even with costs of travel support, and increases adverse maternal and neonatal outcomes. This analysis provides important information for policymakers about economic and health burdens associated with barriers to abortion care in the military.

Effect of interface dead space on the time taken to achieve changes in set FiO2 during T-piece ventilation: is face mask the optimal interface for neonatal stabilisation?

BACKGROUND: T-piece is recommended for respiratory support during neonatal stabilisation. Bench studies have shown a delay >30 s in achieving changes in fraction of inspired oxygen (FiO2) at the airway when using the T-piece. Using a face mask adds dead space (DS) to the patient airway. We hypothesised that adding face mask to T-piece systems adversely affects the time required for a change in FiO2 to reach the patient. METHODS: Neopuff (Fisher and Paykel, Auckland, New Zealand) and rPAP (Inspiration Healthcare, Croydon, UK) were used to ventilate a test lung. DS equivalent to neonatal face masks was added between the T-piece and test lung. Additionally, rPAP was tested with nasal prongs. Time course for change in FiO2 to be achieved at the airway was measured for increase (0.3-0.6) and decrease (1.0-0.5) in FiO2. Primary outcome was time to reach FiO2+/-0.05 of the set target. One-way analysis of variance was used to compare mean time to reach the primary outcome between different DS volumes. RESULTS: In all experiments, the mean time to reach the primary outcome was significantly shorter for rPAP with prongs compared with Neopuff and rPAP with face mask DS (p<0.001). The largest observed difference occurred when testing a decrease in FiO2 with 10 mL tidal volume (TV) without leakage (18.3 s for rPAP with prongs vs 153.4 s for Neopuff with face mask DS). The shortest observed time was 13.3 s when increasing FiO2 with 10 mL TV with prongs with leakage and the longest time was 172.7 s when decreasing FiO2 with 4 mL TV and added face mask DS without leak. CONCLUSION: There was a delay in achieving changes in oxygen delivery at the airway during simulated ventilation attributable to the mask volume. This delay was greatly reduced when using nasal prongs as an interface. This should be examined in clinical trials.

Clinical features of neonatal testicular torsion: A retrospective analysis of 24 cases.

OBJECTIVES: To analyze the clinical characteristics, surgical management decisions, and outcomes of Neonatal testicular torsion (NTT) in order to offer guidance for future clinical practice. METHODS: Retrospectively analyzed the clinical data of patients with NTT who were admitted and underwent surgery from January 2008 to October 2023. RESULTS: A total of 24 neonates were enrolled in this study, all of whom were unilateral cases. Age of onset was 0 d (IQR: 0-1.8), while the median duration of symptoms was 73 h (IQR: 26-199). Clinical manifestation included enlarged scrotum (75 %), changes in scrotal color (79 %), and crying upon palpation (17 %). All patients underwent urgent bilateral exploration and performed by orchiectomy and contralateral orchiopexy. CONCLUSION: NTT primarily occurs prenatally with insidious manifestations, often leading to omission or misdiagnosis. The testicular salvage rate is extremely low. Physicians need to attach importance to neonatal testicular examination, improve the vigilance of NTT. Early bilateral exploration does not necessarily save the affected testes, but it is more important to prevent damage to the contralateral one.

Determining the relationship between severity of proteinuria and adverse maternal and neonatal outcomes in patients with preeclampsia.

OBJECTIVES: To investigate the relationship between the severity of proteinuria and adverse maternal and neonatal outcomes in patients with preeclampsia (PE). DESIGN: Prospective cohort study conducted in Gauteng, South Africaover 12 months. Patientswith PE 18 years or olderwith singleton pregnancieswere recruited. Weincluded248in the final analysis. METHODS: Proteinuria was quantified using urine protein: creatinine ratio (UPCR). Preeclamptic patients' outcomeswere compared according to the UPCR values using regression models and by generating receiver operator characteristic (ROC) curves. Primary maternal outcomes were gestational age (GA) at diagnosis, GA at delivery, development of eclampsia, development of severe features and the need for more than one antihypertensiveagent. Neonatal outcomes were admission to neonatal unit, 5-min APGAR score, need for ventilatory support and early neonatal death. RESULTS: There was a weak but significant negative correlation between GA at delivery and UPCR (Spearman's correlation coefficient (SCC) -0.191, p = 0.002). Most patients (77 %) required >1 agent to control their blood pressure, however there was no correlation between UPCR and the need for additional agents (SCC -0.014, p = 0.828). There was a statistically significant correlation between UPCR and severe features, especially the development of haemolysis, elevated liver enzymes and low platelet (HELLP) syndrome (p = 0.005). There was no significant correlation between neonatal outcomes and UPCR. CONCLUSION: Severity of proteinuria correlated with earlier delivery and development of severe features, specifically HELLP syndrome and pulmonary oedema. There was no correlation between UPCR and requiring additional antihypertensiveagentsor neonatal outcomes.

Urgent surgical exploration for neonatal torsion under spinal anesthesia.

INTRODUCTION/BACKGROUND: The repeated or lengthy use of general anesthesia (GA) in children under three years old is cautioned against due to potential neurodevelopment effects. Spinal anesthesia (SA) has emerged as a safe and effective alternative for routine pediatric urologic procedures. In this study, we describe the use of SA in the urgent surgical treatment of neonatal testicular torsion. OBJECTIVE: We aim to evaluate the safety and efficacy of SA for urgent scrotal exploration in neonates. STUDY DESIGN: We retrospectively collected data on neonates younger than 30 days old undergoing SA for the indication of testicular torsion from May 2018 to June 2022. We recorded patient demographics, adjuvant medications use, and time points for start/stop of spinal injection, procedure, and operating room utilization. RESULTS: Six neonates, with an average age of 1.9 days of life and average weight of 3.4 kg, underwent scrotal exploration for testicular torsion using SA. Four patients (67%) required orchiectomy of the nonviable torsed testicle, and all patients underwent orchiopexy of the unaffected testicle. Mean total operative time was 45.3 (SD 11.7) minutes, including Gomco circumcision in five patients. One patient received preoperative intranasal dexmedetomidine for sedation. Mean time for SA administration was 6.3 (SD 5.5) minutes, with a mean total time in the operating room of 77.3 (SD 9.8) minutes. There were no perioperative or postoperative complications. DISCUSSION: We describe a single institution experience of surgical management of neonatal torsion under SA. In this case series, SA was safely utilized for all neonates involved without the need for conversion to GA or intravenous (IV) sedation. CONCLUSION: The use of SA is safe and efficacious for urgent scrotal exploration for testicular torsion in neonates, even those under 48 h of age. More widespread utilization requires collaboration between pediatric urologists and experienced pediatric anesthesiologists trained in SA.

Correcting Peripherally Inserted Central Catheter Placement by External Manipulation of the Upper Limb Extremity.

Peripherally inserted central catheters (PICCs) play a critical role in neonatal intensive care units (NICUs), facilitating treatment in premature and critically ill neonates. However, achieving optimal PICC placement can present challenges, requiring meticulous monitoring and adjustment. Here, we describe the case of a 52-day-old, 1.9 kg preterm infant in the NICU requiring a central venous catheter for antibiotics and antifungals. Despite initial insertion into the basilic vein of the right forearm, imaging revealed the catheter's deviation into the right internal jugular vein. Leveraging the influence of arm position on catheter tip depth, external manipulation of the infant's right arm successfully repositioned the catheter tip into the superior vena cava (SVC). This case highlights the significant impact of arm positioning on PICC placement and underscores the efficacy of external extremity manipulation as a simple, non-invasive technique to adjust catheter position. Such innovative strategies offer promising alternatives to invasive interventions, emphasizing the importance of dynamic monitoring and adjustment techniques in neonatal PICC management.

Capitalizing on Community Groups to Improve Women's Resilience to Maternal and Child Health Challenges: Protocol for a Human-Centered Design Study in Tanzania.

BACKGROUND: Maternal and neonatal deaths remain a major public health issue worldwide. Income Generation Associations (IGAs) could form a critical entry point to addressing poverty-related contributors. However, there have been limited practical interventions to leverage the power of IGAs in addressing the challenges associated with maternal care and childcare. OBJECTIVE: This study aims to co-design an intervention package with women in IGAs to improve their readiness and resilience to address maternal and child health (MCH) challenges using a human-centered design approach. METHODS: The study will use a qualitative descriptive design with purposefully selected women in IGAs and key MCH stakeholders in the Shinyanga and Arusha Regions of Tanzania. A 4-step adaptation of the human-centered design process will be used involving (1) mapping of IGAs and exploring their activities, level of women's engagement, and MCH challenges faced; (2) co-designing of the intervention package to address identified MCH challenges or needs considering the perceived acceptability, feasibility, and sustainability; (3) validation of the emerging intervention package through gathering insights of women in IGAs who did not take part in initial steps; and (4) refinement of the intervention package with MCH stakeholders based on the validation findings. RESULTS: The participants, procedures, and findings of each co-design step will be presented. More specifically, MCH challenges facing women in IGAs, a list of potential solutions proposed, and the emerging prototype will be presented. As of August 2024, we have completed the co-design of the intervention package and are preparing validation. The findings from the validation of the emerging prototype with a new group of women in IGAs and its refinement through multistakeholder engagement will be presented. A final co-designed intervention package with the potential to improve women's resilience and readiness to handle MCH challenges will be generated. CONCLUSIONS: The emerging intervention package will be discussed given relevant literature on the topic. We believe that subsequent testing and refinement of the package could form the basis for scaling up to broader settings and that the package could then be promoted as one of the key strategies in addressing MCH challenges facing women in low- and middle-income countries.

Adequacy of an In-Neonatal Intensive Care Unit 1T Magnetic Resonance Imaging Compared With 3T Magnetic Resonance Imaging for Clinical Management.

BACKGROUND: This retrospective study aims to assess the added diagnostic utility and clinical value of a 3-Tesla neonatal brain magnetic resonance imaging after obtaining a 1-Tesla magnetic resonance imaging within the neonatal intensive care unit. METHODS: A cohort of 34 infants had an initial 1-Tesla magnetic resonance imaging and repeat imaging within 14 days in a 3-Tesla scanner. All infants were admitted to the level III neonatal intensive care unit at Brigham and Women's Hospital, and all images were interpreted by pediatric neuroradiologists. RESULTS: For 31 infants (91%), the 3-Tesla magnetic resonance imaging showed similar or expected evolution of known findings found on 1 Tesla. For infants with change between the 1-Tesla and 3-Tesla imaging results, there was no clinical impact. CONCLUSION: Images from 1-Tesla magnetic resonance imaging were sufficient for characterizing a wide range of neonatal brain injuries and abnormalities and repeated 3-Tesla magnetic resonance imaging did not yield further clinical benefit.

Identification of a new bovine picornavirus (Boosepivirus) in the Republic of Korea.

IMPORTANCE: Despite advancements in herd management, feeding, and pharmaceutical interventions, neonatal calf diarrhea (NCD) remains a major global health concern. Bacteria, viruses, and parasites are the major contributors to NCD. Although several pathogens have been identified in the Republic of Korea (ROK), the etiological agents of numerous NCD cases have not been identified. OBJECTIVES: To identify, for the first time, the prevalence and impact of Boosepivirus (BooV) on calf diarrhea in the ROK. METHODS: Here, the unknown cause of calf diarrhea was determined using metagenomics We then explored the prevalence of certain pathogens, including BooV, that cause NCD. Seventy diarrheal fecal samples from Hanwoo (Bos taurus coreanae) calves were analyzed using reverse transcriptase and quantitative real-time polymerase chain reaction for pathogen detection and BooV isolate sequencing. RESULTS: The complete genome of BooV was detected from unknown causes of calf diarrhea. And also, BooV was the most frequently detected pathogen (35.7%) among 8 pathogens in 70 diarrheic feces from Hanwoo calves. Co-infection analyses indicated that most BooV-positive samples were solely infected with BooV, indicating its significance in NCD in the ROK. All isolates were classified as BooV B in phylogenetic analysis. CONCLUSIONS AND RELEVANCE: This is the first study to determine the prevalence and molecular characteristics of BooV in calf diarrhea in the ROK, highlighting the potential importance of BooV as a causative agent of calf diarrhea and highlighting the need for further research on its epidemiology and pathogenicity.

Improving care and survival of newborns with surgical conditions in Tanzania (TINY Tanzania): a focus on gastroschisis.

PURPOSE: Gastroschisis is associated with over 90% mortality in many sub-Saharan African countries. The introduction of the Gastroschisis Care Bundle at Muhimbili National Hospital (MNH) increased survival up to 60%. We aim to explain the impact of using implementation science methods to decentralize the care of babies with gastroschisis to other parts of Tanzania. METHODS: We used a Step-Wedge Implementation Science design to scale up gastroschisis care through training of providers, dissemination and current revision of evidence-based care protocols, advocacy, and engagement with stakeholders. We used mixed methods for data collection. Anonymous patient and provider evaluation data were collected using a nationwide Gastroschisis Database via REDCap. We evaluated the implementation and effectiveness of the care bundle in different hospitals in Tanzania. RESULTS: Decentralizing care nationally was feasible, acceptable, and adaptable. A total of nine trainings have been conducted training 420 providers (14 Master Trainers) reaching seven regions of Tanzania. The three advocacy national campaigns have ensured community reach and patient engagement. A countrywide gastroschisis database was developed to collect data on patients with gastroschisis, hosted locally at MNH with 332 patients' data entered in 1 year. The majority (90.2%) were treated using preformed silo bags with an overall survival of 28.5% in all centers. Late presentation and infection remain to be the main challenge. CONCLUSION: To achieve quality and sustainable surgical care, there is a need to design, implement, evaluate, and continuously improve context-relevant strategies to achieve and sustain the survival of neonates with congenital anomalies. Decentralization enables clear connectedness of hospitals, bringing care closer to patients.

How can we reduce neonatal sepsis after universal group B streptococcus screening?

BACKGROUND: Group B Streptococcus (GBS) infection remains a leading cause of newborn morbidity and mortality. The study aimed to determine the adherence rate to the universal screening policy a decade after its introduction. Secondly, whether the timing of antibiotics given in GBS carriers reduces the incidence of neonatal sepsis. METHODS: Delivery records at Hong Kong Baptist Hospital in 2022 were examined to retrieve antenatal and intrapartum details regarding maternal GBS carrier status, previous maternal GBS carrier status, antibiotic treatment, timing of treatment, neonatal condition at birth and whether the neonate had sepsis. Univariate statistics was used to assess the relationship between maternal GBS carrier and neonatal sepsis overall. Incidence of neonatal sepsis was stratified according to mode of delivery and timing of antibiotic. RESULTS: The adherence rate to the universal GBS screening policy was 97%. The risk of neonatal sepsis was 5.45 (95% CI 3.05 to 9.75) times higher in women who were GBS screened positive when compared to non-GBS carriers (p < 0.001). Amongst term neonates from GBS carriers delivered by Caesarean section, the risk of neonatal sepsis significantly decreased by 70% after antenatal antibiotic treatment (p = 0.041) whereas in term neonates delivered vaginally, the risk of neonatal sepsis decreased by 71% (p = 0.022) if intrapartum antibiotic prophylaxis was given 4 or more hours. CONCLUSION: Giving antenatal antibiotic treatment before Caesarean section or intrapartum antibiotic prophylaxis for 4 or more hours before vaginal delivery may decrease the risk of neonatal sepsis in term neonates delivered from GBS carriers.

Delayed sustained lung inflation for preterm neonates in neonatal intensive care unit: a randomized controlled trial.

INTRODUCTION: Sustained lung inflation (SLI) right after birth to decrease the use of mechanical ventilation of preterm infants is controversial because of potential harm. This randomized controlled trial was conducted to evaluate the effectiveness and safety of delayed SLI in neonatal intensive care unit (NICU). METHODS: Preterm neonates requiring continuous positive airway pressure after birth were eligible for enrollment. In the experimental group, SLI with 20 cm H2O for 15 s was conducted by experienced staff in the NICU between 30 min and 24 h after birth. RESULTS: A total of 45 neonates were enrolled into this study, including 24 in the experimental group and 21 in the control group. There was no significant difference in the birth condition between the experimental and control groups, including gestational age (p = 0.151), birth weight (p = 0.692), and Apgar score at 1 min (p = 0.410) and 5 min (p = 0.518). The results showed the duration of respiratory support was shorter in the experimental group than the control group (p = 0.044). In addition, there was no significant difference in the other outcomes, such as pneumothorax, patent ductus arteriosus, and bronchopulmonary dysplasia. CONCLUSION: Our findings indicate that sustained inflation conducted by experienced staff in the NICU is safe. The data suggest that SLI conducted by experienced staff in the NICU after stabilization could serve as an alternative management for preterm infants with respiratory distress. However, the reduction in use of respiratory support should be interpreted cautiously as a result of limited sample size.

Relationship between hepatic function recovery and postoperative cholangitis in neonates undergoing hepaticojejunostomy for biliary atresia.

OBJECTIVE: To explore the association between hepatic function recovery and the incidence of postoperative cholangitis in neonates with biliary atresia (BA) who underwent hepaticojejunostomy. METHODS: We conducted a retrospective analysis of medical records from 173 newborns diagnosed with BA and treated with hepaticojejunostomy (Kasai procedure) between February 2020 and October 2022. Participants were categorized into two cohorts: those who developed cholangitis post-surgery (cholangitis group, n=125) and those who did not (non-cholangitis group, n=48). Liver function indices pre- and post-treatment, the extent of postoperative liver function recovery, and jaundice resolution rates were compared. Risk factors for cholangitis development post-surgery were identified using univariate and multifactorial logistic regression analyses. RESULTS: The cholangitis group exhibited higher surgical weight (P=0.030) and elevated preoperative levels of total bilirubin (TB, P<0.001), direct bilirubin (DB, P<0.001), aspartate aminotransferase (AST, P<0.001), and gamma-glutamyl transferase (GGT, P<0.001). This group also showed better postoperative liver function recovery (P=0.002) and jaundice clearance rates (P=0.003). Logistic regression identified postoperative jaundice clearance (P=0.013), TB (P=0.004), DB (P=0.011), AST (P<0.001), and GGT (P<0.001) as independent risk factors for cholangitis. The nomogram model had a C-index of 0.930 with a goodness-of-fit test p-value of 0.873, and an AUC of 0.930. CONCLUSION: Postoperative jaundice clearance, TB, DB, AST, and GGT are independent risk factors for cholangitis. The nomogram model offers high predictive accuracy for cholangitis development, aiding early intervention and prognosis improvement in high-risk neonates.

Parental stress and associated factors among parents of preterm neonates admitted at neonatal intensive care unit among selected governmental hospitals Addis Ababa, Ethiopia, 2022. An institution-based cross-sectional study.

Background: The birth of a preterm infant and their subsequent admission to the Neonatal Intensive Care Unit (NICU) is a distressing and challenging experience for parents. The stress experienced by parents can have a significant impact on their mental health, parenting behaviors, and the parent-infant relationship. Recognizing and addressing the stressors faced by parents in the NICU is essential for promoting their well-being and facilitating positive parent-infant interactions. Methods: A cross-sectional study was conducted at healthcare facilities. The participants for the study were selected using a systematic sampling method, where the sampling interval (K) was calculated for each hospital. Data collection involved the use of a pretested structured questionnaire administered by interviewers. The collected data was analyzed using the Statistical Package for the Social Sciences (SPSS) version 25.0. Simple and multivariable linear regression analyses were performed. Statistical significance was determined using a p-value of less than 0.05. Results: The accompanying mother (ß = 3.094, 95% CI: 3.615, 6.550), length of NICU stay greater than 10 days (ß = 5.823, 95% CI: 1.759-9.887), the gestational week between 34 -37 weeks (ß = -3.509, 95% CI: -6.358, -.659), parents with college degrees and above (ß = -8.667, 95% CI: (-14.111,3.223), mothers who delivered via cesarean section (ß = 2.468, 95% CI: -1.822, 4.759), parents without a history of neonatal NICU admission (ß = -6.16, 95% CI: -11.69, -.63), and parents whose infant without ventilation (ß = -2.755, 95% CI:. -5.492, -.0189) were significantly associated with parental stress. Conclusion: Parent in this setting revealed high levels of stress during their premature infants' NICU admission. The gestational week, educational status of the parents, mode of admission, and mode of delivery were found to have significant associations with parental stress. It is important for healthcare providers to recognize and understand the stress experienced by parents when caring for families with preterm infants in the NICU. They should provide support and assistance to parents as they navigate the challenges and stress that come with this situation.

Identifying gaps in maternal knowledge and care-seeking for neonatal health: A mixed methods study in rural pregnant women.

BACKGROUND: Knowledge of neonatal danger signs is crucial for timely care-seeking and improved newborn survival. This study assessed this knowledge among pregnant women in rural western Gujarat. MATERIALS AND METHODS: A mixed methods study was conducted among 390 pregnant women selected through a two-stage sampling procedure. Quantitative data were collected using a structured questionnaire. Qualitative data were gathered via in-depth interviews with 20 purposively sampled women. Logistic regression identified determinants of knowledge. Thematic analysis was done for qualitative data. RESULTS: The majority of women were young (220, 56.5% ≤25 years), literate (333, 85%), and from rural backgrounds (320, 82%). Overall, 232 (59.5%) knew about cord care, and 301 (77.2%) correctly identified breastfeeding initiation time. Recognition of key danger signs such as fever (311, 79.7%), vomiting (292, 74.8%), and jaundice (275, 70.5%) was high, but only 70 (18%) identified chest in-drawing. Multiparity (adjusted odds ratio (AOR): 1.4, 95% confidence interval (95% CI): 1.2-3.9), lower age (AOR: 3.8, 95% CI: 2.4-5.8), education (AOR: 3.1, 95% CI: 1.5-6.4), inadequate counseling (AOR: 2.2, 95% CI: 1.82-5.190), and normative delivery (AOR: 2.4, 95% CI: 1.16-5.006) were associated with poor knowledge. Qualitative findings revealed reliance on informal sources, family elders, and financial constraints as key barriers along with limited comprehension of some danger signs. CONCLUSION: Focused interventions via health workers, family members, and community platforms are needed to increase neonatal danger signs awareness among vulnerable women in the region to enable timely care-seeking.

Delivery mode and maternal gestational diabetes are important factors in shaping the neonatal initial gut microbiota.

Background: The infant gut microbiome's establishment is pivotal for health and immune development. Understanding it unveils insights into growth, development, and maternal microbial interactions. Research often emphasizes gut bacteria, neglecting the phageome. Methods: To investigate the influence of geographic or maternal factors (mode of delivery, mode of breastfeeding, gestational diabetes mellitus) on the gut microbiota and phages of newborns, we collected fecal samples from 34 pairs of mothers and their infants within 24 hours of delivery from three regions (9 pairs from Enshi, 7 pairs from Hohhot, and 18 pairs from Hulunbuir) using sterile containers. Gut microbiota analysis by Shotgun sequencing was subsequently performed. Results: Our results showed that geographic location affects maternal gut microbiology (P < 0.05), while the effect on infant gut microbiology was not significant (P = 0.184). Among the maternal factors, mode of delivery had a significant (P < 0.05) effect on the newborn. Specific bacteria (e.g., Bacteroides, Escherichia spp., Phocaeicola vulgatus, Escherichia coli, Staphylococcus hominis, Veillonella spp.), predicted active metabolites, and bacteriophage vOTUs varied with delivery mode. Phocaeicola vulgatus significantly correlated with some metabolites and bacteriophages in the early infant gut (P < 0.05). In the GD group, a strong negative correlation of phage diversity between mother and infants was observed (R = -0.58, P=0.04). Conclusion: In conclusion, neonatal early gut microbiome (including bacteria and bacteriophages) colonization is profoundly affected by the mode of delivery, and maternal gestational diabetes mellitus. The key bacteria may interact with bacteriophages to influence the levels of specific metabolites. Our study provides new evidence for the study of the infant microbiome, fills a gap in the analysis of the infant gut microbiota regarding the virome, and emphasizes the importance of maternal health for the infant initial gut virome.

Effects of Metabolic Syndrome on Pregnancy Outcomes in Women Without Polycystic Ovary Syndrome.

Context: Metabolic syndrome (MetS) is a cluster of metabolic risk factors that predict cardiovascular disease. Previous studies suggested that MetS impaired clinical outcomes in women with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF). Objective: To evaluate the effects of MetS on IVF/intracytoplasmic sperm injection (ICSI) outcomes in women without PCOS. Methods: This retrospective study collected 8539 eligible women without PCOS who came for their first cycle of IVF/ICSI to the Institute of Women, Children and Reproductive Health, Shandong University, from 2017 to 2020, including 1147 subjects in the MetS group and 7392 in the control group. The primary outcome was live birth. Secondary outcomes included other pregnancy outcomes and the risk of maternal and neonatal complications. Results: Women in the MetS group had a lower live birth rate (50.6% vs 54.9%, adjusted odds ratio [aOR] 0.87, 95% CI 0.75-1.00, P = .045) and higher risks of late miscarriage (5.8% vs 3.3%, aOR 1.52, 95% CI 1.02-2.27, P = .041), gestational diabetes mellitus (13.7% vs 7.0%, aOR 1.84, 95% CI 1.30-2.60, P = .001), hypertensive disorder of pregnancy (7.8% vs 3.5%, aOR 1.79, 95% CI 1.14-2.83, P = .012), and preterm birth (9.0% vs 4.4%, aOR 2.03, 95% CI 1.33-3.08, P = .001). Singleton newborns in the MetS group were at higher risk of large for gestational age (33.3% vs 20.5%, aOR 1.66, 95% CI (1.31-2.13), P < .001) but at lower risk of small for gestational age (2.7% vs 6.2%, aOR 0.48, 95% CI 0.25-0.90, P = .023). Conclusion: MetS was associated with adverse IVF/ICSI outcomes in women without PCOS.

Impact of targeted neonatal echocardiography consultations for critically sick preterm neonates.

RATIONALE: Preterm neonates needing rescue treatments with inotropes and/or inhaled nitric oxide (iNO) (acute critical illnesses, ACIs) in neonatal intensive care units (NICUs) are at high risk of mortality. While targeted neonatal echocardiography consultations (TNE) are increasingly used to guide management, its clinical impact need evaluation. OBJECTIVES: To investigate clinical outcomes in relation to TNE utilisation during episodes of ACIs among preterm neonates. METHODS: This retrospective cohort study, conducted at two tertiary NICUs over 10 years, included neonates<37 weeks gestational age (GA) who developed ACIs. Patients receiving TNE-guided care (TNE within 24 hours of treatment initiation) were compared with non-TNE management. Outcomes included predischarge mortality, episode-related mortality (<7 days) and a new diagnosis of intraventricular haemorrhage≥grade 3 (IVH-3). Inverse probability of treatment weighting (IPTW) using propensity score was used to account for confounders, including site, birth years and baseline illness severity. MEASUREMENTS AND MAIN RESULTS: Of 622 included patients, 297 (48%) had TNE; median (IQR) GA at ACI was 26.4 (25.0-28.4) weeks. TNE group demonstrated higher baseline mean airway pressure, oxygen requirement and heart rate and frequently received both inotrope and iNO during ACI. IPTW analysis revealed TNE was associated with lower mortality (adjusted OR (95% CI) 0.75 (0.59 to 0.95)), episode-related mortality (0.54 (0.40 to 0.72)) and death or IVH-3 (0.78 (0.62 to 0.99)). TNE group received more varied inotropic agents, demonstrated earlier improvements in blood pressures, without increasing overall inotrpoic burden. CONCLUSIONS: Among preterm neonates requiring rescue treatments with inotropes/iNO, TNE utilisation to guide clinical management may be associated with improved survival.
