RESUMEN
BACKGROUND: Implementing innovative approaches to vascular access can be challenging in the newborn intensive care unit (NICU). PURPOSE: The purpose of this project was to describe the implementation of extended dwell peripheral intravenous (EPIV) catheters, a vascular access device not widely used in the NICU. The implementation involved (1) designing clinical criteria for EPIV catheter use, (2) education of vascular access NICU nurses, and (3) comparing clinical outcomes between vascular access devices (ie, PIV and EPIV catheters). METHODS: We developed evidence-based clinical criteria guiding the use of vascular access devices. We then developed an educational plan for NICU nurses focused on vascular access. Finally, we collected and compared demographic characteristics and clinical data on catheter type and placement attempts, dwell time, and clinical complications associated with each catheter. RESULTS: EPIV catheters were implemented according to evidence-based criteria by a vascular access NICU nursing team. Fifteen percent of PIV catheter placements required 3 or more attempts compared with just 1% of EPIV catheter placement attempts. EPIV catheters had a longer median dwell time (3.5 vs 1 day) and fewer complications than PIV catheters (P < .001). IMPLICATIONS FOR PRACTICE AND RESEARCH: Implementation of an evidence-based approach to vascular access by a team of NICU nurses may improve clinical outcomes. EPIV catheters may be an appropriate alternative device to PIV catheters due to fewer placement attempts, longer dwell times, and overall fewer complications during use. Future vascular access research in the NICU may include a greater focus on innovative placement strategies, optimal maintenance and infection control, and prevention of complications.

BACKGROUND: While a growing body of literature has established the role of human milk as a mechanism of protection in the formation of the infant gut microbiome, it remains unclear the extent to which this association exists for infants with neonatal opioid withdrawal syndrome. PURPOSE: The purpose of this scoping review was to describe the current state of the literature regarding the influence of human milk on infant gut microbiota in infants with neonatal opioid withdrawal syndrome. DATA SOURCES: CINAHL, PubMed, and Scopus databases were searched for original studies published from January 2009 through February 2022. Additionally, unpublished studies across relevant trial registries, conference proceedings, websites, and organizations were reviewed for possible inclusion. A total of 1610 articles met selection criteria through database and register searches and 20 through manual reference searches. STUDY SELECTION: Inclusion criteria were primary research studies, written in English, published between 2009 and 2022, including a sample of infants with neonatal opioid withdrawal syndrome/neonatal abstinence syndrome, and focusing on the relationship between the receipt of human milk and the infant gut microbiome. DATA EXTRACTION: Two authors independently conducted title/abstract and full-text review until there was consensus of study selection. RESULTS: No studies satisfied the inclusion criteria, which resulted in an empty review. IMPLICATIONS FOR PRACTICE AND RESEARCH: Findings from this study document the paucity of data exploring the associations between human milk, the infant gut microbiome, and subsequent neonatal opioid withdrawal syndrome. Further, these results highlight the timely importance of prioritizing this area of scientific inquiry.

OBJECTIVE: The aim of the study was to assess intestinal inflammatory measures, urinary intestinal fatty acid-binding protein (IFABP), and fecal calprotectin (FC) by gestational age (GA) and postmenstrual age (PMA) and determine the association between intestinal inflammation and growth in preterm infants from birth to hospital discharge. We hypothesized that intestinal inflammation is associated with adverse growth in preterm infants. METHODS: We assayed repeated measures of IFABP and FC in 72 hospitalized preterm infants (<34 weeks' gestation). We calculated weight and length z scores at birth and discharge using the Fenton growth reference. Associations between mean IFABP or FC, growth z scores at discharge, and growth faltering (weight or length z score difference <-0.8 from birth to discharge) were assessed using mixed linear and logistic regression models, adjusted for intrafamilial correlation and potential confounders: GA, sex, birth z score, race/ethnicity, and maternal age. RESULTS: Mean IFABP was greater among infants born at earlier GA and decreased with increasing PMA. Mean FC did not vary by GA or PMA. Higher mean IFABP and FC were associated with lower discharge growth z scores and greater likelihood of growth faltering significant only for mean IFABP and discharge length z score (ßâ=â-0.353, 95% confidence interval [CI]: -0.704 to -0.002) and mean IFABP and length faltering (odds ratio [OR] 1.99, Pâ=â0.018). CONCLUSIONS: Intestinal inflammation, measured by IFABP, was associated with lower length z scores and length faltering at discharge. Interventions to prevent intestinal inflammation may improve linear growth among preterm infants.

Preterm birth affects more than 10% of all births worldwide. Such infants are much more prone to Growth Faltering (GF), an issue that has been unsolved despite the implementation of numerous interventions aimed at optimizing preterm infant nutrition. To improve the ability for early prediction of GF risk for preterm infants we collected a comprehensive, large, and unique clinical and microbiome dataset from 3 different sites in the US and the UK. We use and extend machine learning methods for GF prediction from clinical data. We next extend graphical models to integrate time series clinical and microbiome data. A model that integrates clinical and microbiome data improves on the ability to predict GF when compared to models using clinical data only. Information on a small subset of the taxa is enough to help improve model accuracy and to predict interventions that can improve outcome. We show that a hierarchical classifier that only uses a subset of the taxa for a subset of the infants is both the most accurate and cost-effective method for GF prediction. Further analysis of the best classifiers enables the prediction of interventions that can improve outcome.

BACKGROUND: While studies from large cities affected by coronavirus disease 2019 (COVID-19) have reported on the prevalence of SARS-CoV-2 in the context of universal testing during admission for delivery, the patient demographic, social and clinical factors associated with SARS-CoV-2 infection in pregnant women are not fully understood. OBJECTIVE: To evaluate the epidemiological factors associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in women admitted for labour and delivery, in the context of universal screening at four Boston-area hospitals. METHODS: In this prospective cohort study, we reviewed the health records of all women admitted for labour and delivery at four hospitals from the largest health system in Massachusetts between 19 April 2020 and 27 June 2020. We calculated the risk of SARS-CoV-2 infection, including asymptomatic infection. We calculated associations between SARS-CoV-2 infection and demographic and clinical characteristics. RESULTS: A total of 93 patients (3.2%, 95% confidence interval 2.5, 3.8) tested positive for SARS-CoV-2 infection on admission for labour and delivery out of 2945 patients included in the analysis; 80 (86.0%) of the patients who tested positive were asymptomatic at the time of testing. Factors associated with SARS-CoV-2 infection included the following: younger age, obesity, African American or Hispanic race/ethnicity, residence in heavily affected communities (as measured in cases reported per capita), presence of a household member with known SARS-CoV-2 infection, non-health care essential worker occupation and MassHealth or Medicaid insurance compared to commercial insurance. 93.8% of patients testing positive for SARS-CoV-2 on admission had one or more identifiable factors associated with disease acquisition. CONCLUSIONS: In this large sample of deliveries during the height of the surge in infections during the spring of 2020, SARS-CoV-2 infection was largely concentrated in patients with distinct demographic characteristics, those largely from disadvantaged communities. Racial disparities seen in pregnancy persist with respect to SARS-CoV-2 infection.

BACKGROUND: Preterm infants routinely require enteral feeding via nasogastric or orogastric tubes as an alternative to oral feeding to meet their nutritional needs. Anecdotal evidence suggests variations in practice related to correct tube placement and assessment of feed intolerance. PURPOSE: To determine the current practices of enteral feeding tube placement confirmation and gastric residual (GR) aspiration of neonatal clinicians in Australia. METHODS: A cross-sectional online survey comprising 24 questions was distributed to nursing and medical health professionals working in Australian neonatal care units through 2 e-mail listservs made available by professional organizations. FINDINGS: The survey was completed by 129 clinicians. A single method was practiced by 50% of the clinicians in confirming tube placement, and most common practice was assessing the pH of GR aspirate. The majority of respondents (96%) reported that they relied on GR aspiration and clinical signs to determine feeding tolerance and subsequent decisions such as ceasing or decreasing feeds. However, the frequency of aspiration, the amount and color of aspirate considered to be normal/abnormal, and decisions on whether to replace gastric aspirate or whether aspiration should be performed during continuous tube feeding varied. IMPLICATION FOR PRACTICE: This study demonstrated considerable variability in clinical practice for enteral feeding tube placement confirmation and GR aspiration despite most respondents reporting using a unit-based clinical practice guideline. Our study findings highlight the need for not only developing evidence-based practice guidelines for safe and consistent clinical practice but also ensuring that these guidelines are followed by all clinicians. IMPLICATION FOR RESEARCH: Further research is needed to establish evidence-based methods both for enteral feeding tube placement confirmation and for the assessment of feeding intolerance during tube feeding. In addition, the reasons why evidence-based methods are not followed must be investigated.

In the last 20 years, qualitative research scholars have begun to interrogate methodological and analytic issues concerning online research settings as both data sources and instruments for digital methods. This article examines the adaptation of parts of a qualitative research curriculum for understanding online communication settings. I propose methodological best practices for researchers and educators that I developed while teaching research methods to undergraduate and graduate students across disciplinary departments and discuss obstacles faced during my own research while gathering data from online sources. This article confronts issues concerning the disembodied aspects of applying what in practice should be rooted in a humanistic inquiry. Furthermore, as some approaches to online qualitative research as a digital method grow increasingly problematic with the development of new data mining technologies, I will also briefly touch upon borderline ethical practices involving data-scraping-based qualitative research.

This review describes current understandings about the nature of the very low birth weight infant (VLBW) gut microbiome. VLBW infants often experience disruptive pregnancies and births, and prenatal factors can influence the maturity of the gut and immune system, and disturb microbial balance and succession. Many VLBWs experience rapid vaginal or Caesarean births. After birth these infants often have delays in enteral feeding, and many receive little or no mother's own milk. Furthermore the stressors of neonatal life in the hospital environment, common use of antibiotics, invasive procedures and maternal separation can contribute to dysbiosis. These infants experience gastrointestinal dysfunction, sepsis, transfusions, necrotizing enterocolitis, oxygen toxicity, and other pathophysiological conditions that affect the normal microbiota. The skin is susceptible to dysbiosis, due to its fragility and contact with NICU organisms. Dysbiosis in early life may resolve but little is known about the timing of the development of the signature gut microbiome in VLBWs. Dysbiosis has been associated with a number of physical and behavioral problems, including autism spectrum disorders, allergy and asthma, gastrointestinal disease, obesity, depression, and anxiety. Dysbiosis may be prevented or ameliorated in part by prenatal care, breast milk feeding, skin to skin contact, use of antibiotics only when necessary, and vigilance during infancy and early childhood.

BACKGROUND: Intestinal colonization during infancy is important to short- and long-term health outcomes. Bacteroides, an early member of the intestinal microbiome, is necessary for breaking down complex molecules within the intestine and function to assist the body's immune system in fighting against potentially harmful pathogens. Little is known about the colonization pattern of Bacteroides in preterm infants during the early neonatal period. PURPOSE: This study measured Bacteroides colonization during the early neonatal period in a population of preterm infants, based on clinical factors including mode of birth, antibiotics, and nutrition. METHODS: Bacterial DNA was isolated from 144 fecal samples from 29 preterm infants and analyzed using quantitative real-time polymerase chain reaction. Analyses included liner mixed models to determine which clinical factors affect Bacteroides colonization of the infant gut. RESULTS: We found that infants born via vaginal canal had a higher rate of increase in Bacteroides than infants born via cesarean section (P < .001). We did not find significant associations between antibiotic administration and differences in nutritional exposures with Bacteroides colonization. IMPLICATIONS FOR PRACTICE: These findings highlight the significant influence of mode of birth on Bacteroides colonization. While mode of birth is not always modifiable, these study findings may help develop interventions for preterm infants born via cesarean section aimed at overcoming delayed Bacteroides colonization. IMPLICATIONS FOR RESEARCH: Greater study of the intestinal microbiome and the clinical factors relevant to the preterm infant is needed so that interventions may be developed and tested, resulting in optimal microbial and immune health.

Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency affecting premature infants. A better understanding of the clinical signs and symptoms associated with the disease may result in an improved ability to more effectively intervene in patient care. One of the clinical signs that have not been fully explored is the stooling pattern of preterm infants. This retrospective case-control study included 258 premature infants born prior to 29 weeks of gestation: 129 infants with NEC and 129 gestational age-matched controls. Data were collected from the medical record for the first 28 postnatal days. The relationships between the stooling pattern of premature infants and NEC were assessed via nonparametric techniques and linear mixed models. We identified few differences in the stooling pattern among infants with NEC and their unaffected counterparts. During the first week following birth, infants with NEC passed stool more frequently than controls. However, we found that these infants were taking nothing by mouth for fewer days in the first week following birth compared with controls. We also found that infants who developed NEC were fed smaller proportions of breast milk than healthy controls. Aberrant gut motility has been associated with prematurity and inflammatory bowel disease. However, our analyses did not identify any major differences in the stooling pattern among NEC case patients and controls. While further analyses may be needed, clinical suspicion for NEC should not be overwhelmingly influenced by the stooling pattern observed during the early neonatal period.

Preparing the next generation of nursing scientists to conduct high-impact, competitive, sustainable, innovative, and interdisciplinary programs of research requires that the curricula for PhD programs keep pace with emerging areas of knowledge and health care/biomedical science. A field of inquiry that holds great potential to influence our understanding of the underlying biology and mechanisms of health and disease is omics. For the purpose of this article, omics refers to genomics, transcriptomics, proteomics, epigenomics, exposomics, microbiomics, and metabolomics. Traditionally, most PhD programs in schools of nursing do not incorporate this content into their core curricula. As part of the Council for the Advancement of Nursing Science's Idea Festival for Nursing Science Education, a work group charged with addressing omics preparation for the next generation of nursing scientists was convened. The purpose of this article is to describe key findings and recommendations from the work group that unanimously and enthusiastically support the incorporation of omics content into the curricula of PhD programs in nursing. The work group also calls to action faculty in schools of nursing to develop strategies to enable students needing immersion in omics science and methods to execute their research goals.

Necrotizing enterocolitis, characterized by sudden onset and rapid progression, remains the most significant gastrointestinal disorder among premature infants. In seeking a predictive biomarker, we found intestinal fatty acid binding protein, an indicator of enterocyte damage, was substantially increased within three and seven days before the diagnosis of necrotizing enterocolitis.

Heat waves can be lethal and routinely prompt public warnings about the dangers of heat. With climate change, extreme heat events will become more frequent and intense. However, little is known about public awareness of heat warnings or behaviors during hot weather. Awareness of heat warnings, prevention behaviors, and air conditioning (AC) prevalence and use in New York City were assessed using quantitative and qualitative methods. A random sample telephone survey was conducted in September 2011 among 719 adults and follow-up focus groups were held in winter 2012 among seniors and potential senior caregivers. During summer 2011, 79 % of adults heard or saw a heat warning. Of the 24 % who were seniors or in fair or poor health, 34 % did not own AC or never/rarely used it on hot days. Of this subgroup, 30 % were unaware of warnings, and 49 % stay home during hot weather. Reasons for not using AC during hot weather include disliking AC (29 %), not feeling hot (19 %), and a preference for fans (18 %). Seniors in the focus groups did not perceive themselves to be at risk, and often did not identify AC as an important health protection strategy. While heat warnings are received by most New Yorkers, AC cost, risk perception problems, and a preference for staying home leave many at risk during heat waves. Improving AC access and risk communications will help better protect the most vulnerable during heat waves.

Optimal nutrition during infancy is critical not only to support the dramatic growth and development that takes place during the first 12 months following birth but also for establishing a healthy immune response throughout childhood and across the life span. The normative standards for infant feeding and nutrition are breast-feeding and human breast milk. However, in cases in which human breast milk is not available, infant formula is substituted. Providing optimal patient care that results in the best clinical outcomes depends on understanding the unique attributes of the 3 main sources of nutrition for newborns. This state of the science review provides an update on the macronutrient and immunological content of human milk, donor milk, and infant formula and highlights the relevance of these sources of infant nutrition on the development of immune system.

Robust methodologies for the analysis of fecal material will facilitate the understanding of gut (patho)physiology and its role in health and disease and will help improve care for individual patients, especially high-risk populations, such as premature infants. Because lipidomics offers a biologically and analytically attractive approach, we developed a simple, sensitive, and quantitatively precise method for profiling intact lipids in fecal material. The method utilizes two separate, complementary extraction chemistries, dichloromethane (DCM) and a methyl tert-butyl ether/hexafluoroisopropanol (MTBE) mixture, alone or with high pressure cycling. Extracts were assessed by liquid chromatography-high-resolution mass spectrometry-based profiling with all ion higher energy collisional dissociation fragmentation in both positive and negative ionization modes. This approach provides both class-specific and lipid-specific fragments, enhancing lipid characterization. Solvents preferentially extracted lipids based on hydrophobicity. More polar species preferred MTBE; more hydrophobic compounds preferred DCM. Pressure cycling differentially increased the yield of some lipids. The platform enabled analysis of >500 intact lipophilic species with over 300 lipids spanning 6 LIPID MAPS categories identified in the fecal matter from premature infants. No previous report exists that provides these data; thus, this study represents a new paradigm for assessing nutritional health, inflammation, and infectious disease in vulnerable populations.

Postnatal acquisition of the microbiome is critical to infant health. In preterm infants, empiric use of antibiotics is common, with significant health consequences. To understand the influence of antibiotics on acquisition of the microbiome over time, we longitudinally profiled microbial 16S rRNA in the stool of 79 preterm infants during their hospitalization in the intensive care unit and compared antibiotic treated and untreated infants. Despite similar clinical presentation, antibiotic treated infants had strong deviations in the content, diversity, and most dramatically, temporal stability of their microbiome. Dysbiosis and fluctuations of microbiome content persisted long after antibiotic exposure, up to hospital discharge. Microbiome diversity was dominated by a few common bacteria consistent among all infants. Our findings may inform clinical practice related to antibiotic use and targeted microbial interventions aimed at overcoming the adverse influence of antibiotics on the microbiome of preterm infants at specific developmental time points.
RESUMEN
OBJECTIVE: To compare pH of human milk types (mother's own milk (MOM), pasteurized donor human milk (PDHM), fortified MOM, and fortified PDHM) fed to preterm infants. STUDY DESIGN: This observational study consisted of 63 mother-infant dyads < 34 weeks gestation. Human milk samples (n = 245), along with maternal factors, were collected for pH analysis. pH of MOM was analyzed over the course of lactation accounting for fortification status, postpartum day, and storage conditions. RESULTS: Mean pH of MOM was slightly acidic at 6.60 ± 0.28, which was significantly higher (p < 0.05) than other milk types. pH of MOM varied by fortification, postpartum day, and maternal vegetable/fiber intake. There was a significant interaction between fortification status and postpartum day; pH of MOM decreased over time, while pH of fortified MOM increased over time. CONCLUSION: pH of human milk varied by type. pH of MOM was significantly associated with fortification status, postpartum day, and maternal vegetable/fiber intake.

Objective: To assess maternal dietary intake during pregnancy and adherence to the 2020-2025 pregnancy-specific Dietary Guidelines for Americans (DGA). Methods: This was a retrospective observational study. The study population consisted of women who gave birth to term infants (>37 weeks of gestation). Participants were given the Dietary Screener Questionnaire (DSQ) after birth and asked to recall their dietary intake in the last month of pregnancy. Participants' estimated dietary intakes were then compared to the 2020-2025 DGA which includes specific recommendations for pregnant women. Results: Out of 51 women who completed the DSQ, none consumed the recommended amounts of all surveyed dietary factors. Specifically, only one woman (2%) met the recommended intake of fruits, 11 women (22%) met the recommended intake of calcium, 25 women (49%) exceeded the recommended upper limit for added sugar intake, and none of the women (0%) met the intake of vegetables, whole grains, dairy and fiber. Conclusion: Women in our study did not adhere to the pregnancy-specific DGA recommendations in the last month of pregnancy. Our findings underscore the need to increase maternal nutritional awareness and education to improve adherence to the DGA.
RESUMEN
PURPOSE: We determined the proportion of cancer survivors who met each of five health behavior guidelines recommended by the American Cancer Society (ACS), including consuming fruits and vegetables at least five times/day, maintaining a body mass index (BMI) < 30 kg/m2, engaging in 150 min or more of physical activity weekly, not currently smoking, and not excessively drinking alcohol. METHODS: Using data from the 2019 Behavioral Risk Factor Surveillance System (BRFSS), 42,727 survey respondents who reported a previous diagnosis of cancer (excluding skin cancer) were included. Weighted percentages with 95% confidence intervals (95% CI) were estimated for the five health behaviors accounting for BRFSS' complex survey design. RESULTS: The weighted percentage of cancer survivors who met ACS guidelines was 15.1% (95%CI: 14.3%, 15.9%) for fruit and vegetable intake; 66.8% (95%CI: 65.9%, 67.7%) for BMI < 30 kg/m2; 51.1% (95%CI: 50.1%, 52.1%) for physical activity; 84.9% (95%CI: 84.1%, 85.7%) for not currently smoking; and 89.5% (95%CI: 88.8%, 90.3%) for not drinking excessive alcohol. Adherence to ACS guidelines among cancer survivors generally increased with increasing age, income, and education. CONCLUSIONS: While the majority of cancer survivors met the guidelines for not smoking and limiting alcohol drinking, one-third had elevated BMI, almost half did not meet recommended physical activity levels, and the majority had inadequate fruit and vegetable intake. IMPLICATIONS FOR CANCER SURVIVORS: Adherence to guidelines was lowest among younger cancer survivors and those with lower income and education, suggesting these may be populations where resources could be targeted to have the greatest impact.
