J Perinatol 2024:10.1038/s41372-024-01981-9. [PMID: 38678081 DOI: 10.1038/s41372-024-01981-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 04/14/2024] [Accepted: 04/17/2024] [Indexed: 04/29/2024]
Abstract
OBJECTIVE This prospective study compared PIVKA-II and PT-INR levels in infants who received two vitamin K (VK) prophylactic regimens. METHODS A single institution administered 119 healthy newborns 2 mg of VK syrup. Infants were assigned to a 3-time regimen (n = 56) with VK at birth, five days (5D), and 1-month-old (1 M), or a 13-time regimen (n = 63) with VK at birth, 5D, and then weekly for 11 weeks. RESULTS The 13-time regimen significantly lowered PIVKA-II and reduced PT-INR at 1 M in both breastfed (PIVKA-II: 18-16 mAU/mL, p = 0.02; PT-INR: 1.37-1.13, p < 0.01) and formula-fed infants (PIVKA-II: 18-15 mAU/mL, p = 0.01; PT-INR: 1.54-1.24, p < 0.01), compared to baseline measurements taken at 5D. The 3-time regimen did not significantly alter PIVKA-II levels and only improved PT-INR (2.00-1.50, p < 0.01) in formula-fed infants. CONCLUSION The 13-time VK regimen significantly enhanced coagulation profiles more effectively than the 3-time regimen.

Abstract
BACKGROUND/AIM Late vitamin K deficiency bleeding (VKDB) during early infancy is a serious problem worldwide. Vitamin K (VK) deficiency commonly occurs in newborns who are exclusively breastfed. Protein Induced by VK Absence (PIVKA-II) has been identified as an early indicator of subclinical VK deficiency in neonates, surpassing prothrombin time. To assess PIVKA-II levels at 48 h, 1 and 3 months of age in full-term newborns who were exclusively breastfed and received varying VKDB prophylaxis regimens. METHODS A prospective observational study was conducted in four hospitals, enrolling 105 newborns. PIVKA-II levels were measured using a sandwich-type enzyme-linked immunosorbent assay. RESULTS At 48 h of age, there was no significant difference in PIVKA-II concentrations between newborns who received intramuscular administration of 1 mg of phylloquinone (VK1) and those who received oral administration of 2 mg of VK1 at birth. At 1 and 3 months of life, infants who received any supplementation regimen between 2 and 14 weeks exhibited significantly lower PIVKA-II concentrations compared to infants who received only 1 mg of intramuscular VK1 at birth. The prophylaxis involving a dose of 1 mg of intramuscular VK1 at birth followed by oral administration of 150 μg/day of VK1 from the 2nd to the 14th week of life showed the lowest PIVKA-II blood concentrations. CONCLUSIONS Oral supplementation of VK1 after discharge significantly reduced PIVKA-II concentrations in exclusively breastfed term infants. These findings suggest the importance of oral VK1 supplementation in exclusively breastfed infants during their first 3 months of life to avoid the risk of VK insufficiency.

Abstract
Newborns are prone to hemorrhagic disease due to vitamin K deficiency for multiple reasons, including vitamin K absence in breast milk and formula preparation, sterile gut with limited absorption, and lack of placental transfer. Despite the importance of vitamin K administration at birth in preventing hemorrhagic disease in infants, some parents still refuse administration to their newborns. One of the unexpected but preventable reasons is the language barrier related to special dialects, resulting in misunderstanding the benefits of vitamin K administration and complications related to vitamin K deficiency. We present a case of hemorrhagic disease of the newborn due to vitamin K deficiency following the parental refusal of postnatal prophylactic vitamin K due to a language barrier that resulted in miscommunication. Although appropriate education was provided to the family via Spanish interpreter as requested, it was later revealed that the family was speaking a special dialect, and they did not fully understand the importance of vitamin K prophylaxis. The patient experienced intracranial hemorrhage with full recovery after treatment and surgical intervention. Upon reviewing the case, the parents were speaking a rare dialect of Spanish, that was not known to the Spanish medical interpreters. A combination of a Spanish medical translator and a family friend was necessary for effective communication with the family.

Abstract
BACKGROUND There is no consensus on optimal nutrition for preterm infants, leading to substantial practice variation. We aimed to assess the quality of nutrition guidelines for preterm infants, the consistency of recommendations, and the gaps in recommendations. METHODS We searched databases and websites for nutrition guidelines for preterm infants before first hospital discharge, which were endorsed, prepared, or authorized by a regional, national, or international body, written in English, and published between 2012 and 2023. Two reviewers independently screened articles and extracted the recommendations. Four reviewers appraised the included guidelines using Appraisal of Guidelines, Research, and Evaluation II. RESULTS A total of 7051 were identified, with 27 guidelines included, 26% of which were high in quality. Most guidelines lacked stakeholder involvement and rigor of development. We found considerable variation in recommendations, many of which lacked details on certainty of evidence and strength of recommendation. Recommendations for type of feed and breastmilk fortification were consistent among high-quality guidelines, but recommendations varied for intakes of almost all nutrients and monitoring of nutrition adequacy. Different guidelines gave different certainty of evidence for the same recommendations. Most gaps in recommendations were due to very low certainty of evidence. CONCLUSION Future development of nutrition guidelines for preterm infants should follow the standard guideline development method and ensure the rigorous process, including stakeholders' involvement, to improve the reporting of strength of recommendation, certainty of evidence, and gaps in recommendation. Evidence is needed to support recommendations about macro and micronutrient intakes, breastmilk fortification, and markers on adequacy of intake of different nutrients.

Abstract
Hemorrhagic disease of the newborn, more aptly termed "Vitamin K Deficiency Bleeding (VKDB)," has long been recognized as a cause of significant morbidity and mortality in early infancy. A single intramuscular dose of vitamin K administered at birth has virtually eliminated VKDB, and this prophylactic regimen has been recommended by the American Academy of Pediatrics since 1961. Although most newborns in the United States receive vitamin K at birth, a growing number of parents are hesitant about this intervention, citing concerns about harm from the injection, preservatives contained in the medication, and clashes with personal belief systems. Ultimately, there is distrust in the medical establishment as many of these parents also opt out of newborn ophthalmic prophylaxis and importantly, childhood vaccinations, establishing a dangerous public health precedent that will lead to resurgence of vaccine-preventable diseases. Various shared decision making models and educational efforts can assist newborn health care professionals in addressing these parental concerns so that VKDB can be effectively prevented in all newborns.

Abstract
Studies from the past 50 years have contributed to the expanding knowledge regarding developmental hemostasis. This is a dynamic process that begins in the fetal phase and is characterized by physiological variations in platelet counts and function, and concentrations of most coagulation factors and the native coagulation inhibitors in early life, as compared with adulthood. The developmental hemostasis studies since the 1980 to 1990s established the laboratory reference values for coagulation factors. It was only a decade or two later, that thromboelastography (TEG) or (rotational thromboelastometry [ROTEM]) as well as thrombin generation studies, provided special pediatric reference values along with the ability to evaluate clot formation and lysis. In addition, global whole blood-based clotting assays provided point of care guidance for proper transfusion support to children hospitalized in intensive care units or undergoing surgery. Although uncommon, thrombosis in children and neonates is gaining increasing recognition, typically as a secondary complication in sick children. Bleeding in children, and particularly intracerebral hemorrhage in newborns, still represent a therapeutic challenge. Notably, our review will outline the advancements in understanding developmental hemostasis and its manifestations, with respect to the pathophysiology of thrombosis and bleeding complications in young children. The changes of transfusion policy and approach to thrombophilia testing during the last decade will be mentioned. Subsequently, a brief summary of the data on anticoagulant treatments in pediatric patients will be presented. Finally, we will point out the 10 most cited articles in the field of pediatric and neonatal hemostasis.

Abstract
BACKGROUND The American Academy of Pediatrics recommends birth doses of vitamin K, erythromycin ointment, and the hepatitis B vaccine, but the relationship between birth medication administration and childhood immunization compliance is understudied. The objective of this study is to evaluate rates of newborn medication administration, and risk factors for refusal in military beneficiaries and determine the relationship between medication refusal and under-immunization at 15 months. METHODS A retrospective chart review was completed for all term and late preterm infants born at Brooke Army Medical Center, San Antonio, TX, from January 1, 2016, to December 31, 2019. The electronic medical record was queried for birth medication administration, maternal age, active-duty status, rank, and birth order. Childhood immunization records were extracted for all patients who continued care at our facility. A patient was considered completely immunized if they had received at least 22 vaccines by 15 months: three doses of the hepatitis B vaccine [PediarixTM], two doses of the rotavirus vaccine [RotarixTM], four doses of the DTAP vaccine [PediarixTM and Acel-ImmuneTM], three doses of Haemophilus influenza B vaccine [PedvaxhibTM], four doses of pneumococcal [Prevnar 13TM], three doses of IPV [PediarixTM], one dose of measles, mumps, and rubella [MMRTM], one dose of varicella [VarivaxTM] and one dose of hepatitis A vaccine [HarvixTM]. RESULTS Seven thousand one hundred and forty infants were included; 99.3% received vitamin K, 98.8% received erythromycin ointment, and 93.8% received the hepatitis B vaccine. Refusal of the erythromycin ointment and hepatitis B vaccine was associated with older maternal age and higher birth order. Childhood immunization records were available for 607 infants; 7.2% (n = 44) were under-immunized by 15 months, with no infants being non-immunized. Refusal of the hepatitis B vaccine (RR: 2.9 (CI 1.16-7.31)) only at birth was associated with a higher risk of being under-immunized. CONCLUSIONS Refusal of the hepatitis B vaccine in the nursery is associated with a risk of being under-immunized in childhood. Obstetric and pediatric providers should be aware of this association for appropriate family counseling.

Abstract
Vitamin K is essential for the process of coagulation. In its absence, severe and sometimes fatal bleeding events can occur, especially in newborns. Vitamin K prophylaxis at birth has been shown to prevent morbidity and mortality associated with vitamin K deficiency bleeding (VKDB) and is recommended by multiple organizations including the American Academy of Pediatrics and the World Health Organization. Pediatricians should feel comfortable explaining the risks and benefits of vitamin K prophylaxis to families and should be equipped to recognize signs of VKDB, especially given increasing rates of parental refusal. This article aims to improve understanding of VKDB, including prevention, early recognition, and treatment. [Pediatr Ann. 2023;52(2):e42-e45.].

Abstract
Newborns are susceptible to postnatal Vitamin K deficiencies from limited placental transfer, gastrointestinal absorption, and bioavailability in breast milk and formula preparations. For over 50 years, the American Academy of Pediatrics has recommended prophylactic vitamin K to prevent hemorrhagic disease in newborns. Yet, public skepticism contributes to increasing refusal rates. We present three cases of vitamin K-dependent bleeding following parental refusal of postnatal prophylaxis. Two patients experienced intracranial hemorrhage with resultant neurological devastation and mortality, respectively. The third child presented with symptomatic hematuria. Perinatal providers must partner with families and advocate vitamin K prophylaxis to limit unnecessary morbidity and mortality.

Abstract
BACKGROUND There is near-global consensus that all newborns be given parenteral vitamin K1 (VK1 ) at birth as prophylaxis against VK deficiency bleeding (VKDB). Breastmilk has a low VK content and cases of late VKDB are reported in exclusively breastmilk-fed preterm infants despite VK prophylaxis at birth. OBJECTIVES To assess the prevalence of functional VK insufficiency in preterm infants based on elevated under-γ-carboxylated (Glu) species of Gla proteins, factor II (PIVKA-II), and osteocalcin (GluOC), synthesized by liver and bone, respectively. PATIENTS/METHODS Prospective, multicenter, observational study in preterm infants born <33 weeks' gestation. Blood samples and dietary history were collected before hospital discharge, and after discharge at 2-3 months' corrected age. Outcome measures were serum VK1 , PIVKA-II, and %GluOC (GluOC as a percentage of the sum of GluOC plus GlaOC) compared between exclusively breastmilk-fed and formula/mixed-fed infants after discharge. RESULTS After discharge, breastmilk-fed babies had significantly lower serum VK1 (0.15 vs. 1.81 μg/L), higher PIVKA-II (0.10 vs. 0.02 AU/ml) and higher %GluOC (63.6% vs. 8.1%) than those receiving a formula/mixed-feed diet. Pre-discharge (based on elevated PIVKA-II), only one (2%) of 45 breastmilk-fed infants was VK insufficient. After discharge, eight (67%) of 12 exclusively breastmilk-fed babies were VK insufficient versus only one (4%) of 25 formula/mixed-fed babies. CONCLUSIONS Preterm infants who remain exclusively or predominantly human breastmilk-fed after neonatal unit discharge are at high risk of developing subclinical VK deficiency in early infancy. Routine postdischarge VK1 supplementation of breastfed infants to provide intakes comparable to those from formula milks should prevent this deficiency.

Three Different Regimens for Vitamin K Birth Prophylaxis in Infants Born Preterm: A Randomized Clinical Trial. J Pediatr 2022; 255:98-104. [PMID: 36343740 DOI: 10.1016/j.jpeds.2022.10.031] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2022] [Revised: 09/30/2022] [Accepted: 10/30/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE To study the efficacy of 3 different vitamin K birth prophylaxis regimens in infants born premature. STUDY DESIGN This was an open-label, parallel-group, randomized clinical trial conducted in a tertiary neonatal care unit in India. Infants born very preterm (≤32 weeks) and/or with very low birth weight (≤1500 g) were included. In each arm, 25 babies were enrolled. Babies were randomized to receive 1.0 mg, 0.5 mg, or 0.3 mg intramuscular (IM) vitamin K1 at birth. Protein induced by vitamin K absence - II (PIVKA-II) levels were assessed at birth, and on days 5 and 28, along with the frequency of death, bleeding manifestations, intraventricular hemorrhage, necrotizing enterocolitis, bilirubin levels, and duration of phototherapy. The primary outcome was comparison of PIVKA-II levels on day 5 of life. RESULTS All the 3 regimens resulted in similar proportion of vitamin K subclinical sufficiency (PIVKA-II < 0.028 AU/mL) infants on day 5 (1 mg - 100%; 0.5 mg - 91.7%; 0.3 mg - 91.7%, P = .347), with no significant difference in median (IQR) PIVKA-II levels (AU/mL): 1 mg 0.006 (0.004, 0.009); 0.5 mg 0.008 (0.004, 0.009); 0.3 mg 0.006 (0.003, 0.009), P = .301. However, on day 28, there was a significant decrease in the proportion of vitamin K-sufficient infants in the 0.3-mg IM group (72.7%) compared with the 1.0-mg (100%) or 0.5-mg (91.3) groups. The 1.0-mg group had significantly greater bilirubin levels and duration of phototherapy. None of the other clinical outcomes were statistically different. CONCLUSIONS Both 1-mg and 0.5-mg IM vitamin K birth prophylaxis resulted in high sufficiency on follow-up, compared with 0.3 mg. The current recommendation of 0.5-1 mg IM vitamin K birth prophylaxis for infants born preterm, needs to be continued. TRIAL REGISTRATION CTRI/2022/02/040396.

[PMID: 35551587 PMCID: PMC9095437 DOI: 10.1007/s10995-022-03423-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 03/10/2022] [Accepted: 03/10/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND The American Academy of Pediatrics recommends one intramuscular (IM) vitamin K injection at birth to prevent Vitamin K Deficiency Bleeding of the Newborn (VKDB). Among factors associated with IM vitamin K refusal, investigators have reported an increased frequency of IM vitamin K refusal among parents who select midwife-assisted deliveries. Reasons behind this association are unclear. METHODS To understand the perspectives of midwives on IM vitamin K prophylaxis and approach to counseling parents using qualitative methodology, we conducted in-depth semi-structured interviews of midwives associated with 3 tertiary academic medical centers and surrounding communities in Connecticut, Iowa and Michigan. We used the grounded theory approach and the constant comparative method until saturation was reached. RESULTS We interviewed 19 white female midwives from different training pathways. Participants who were Certified Nurse Midwives (CNMs) routinely recommended IM vitamin K prophylaxis and Certified Professional Midwives (CPMs) took a more neutral approach. The following 4 themes emerged: (1) Emphasis on an educational approach to counseling that supports parents' decision-making authority; (2) Low-intervention philosophy in the midwifery model of care attracts certain parents; (3) Need for relationship building between midwives and pediatricians and (4) Opportunities for the future. CONCLUSIONS Midwives in our study perceived that the midwifery model of care, the focus on physiologic birth and prioritizing parents' decision-making autonomy appears to attract a sub-set of expectant parents with certain belief systems who question interventions such as IM vitamin K prophylaxis. There are opportunities for better collaboration between midwives and pediatricians.

Abstract
Breastfeeding and human milk are the normative standards for infant feeding and nutrition. The short- and long-term medical and neurodevelopmental advantages of breastfeeding make breastfeeding or the provision of human milk a public health imperative. The American Academy of Pediatrics (AAP) recommends exclusive breastfeeding for approximately 6 months after birth. Furthermore, the AAP supports continued breastfeeding, along with appropriate complementary foods introduced at about 6 months, as long as mutually desired by mother and child for 2 years or beyond. These recommendations are consistent with those of the World Health Organization (WHO). Medical contraindications to breastfeeding are rare. The AAP recommends that birth hospitals or centers implement maternity care practices shown to improve breastfeeding initiation, duration, and exclusivity. The Centers for Disease Control and Prevention and The Joint Commission monitor breastfeeding practices in United States hospitals. Pediatricians play a critical role in hospitals, their practices, and communities as advocates of breastfeeding and, thus, need to be trained about the benefits of breastfeeding for mothers and children and in managing breastfeeding. Efforts to improve breastfeeding rates must acknowledge existing disparities and the impact of racism in promoting equity in breastfeeding education, support, and services.
