Analysis of noise levels in the neonatal intensive care unit: the impact of clinical microsystems.

Reorganization of neonatal intensive care by introducing clinical microsystems may help to allocate nursing time more appropriately to the needs of patients. However, there is concern that cohorting infants according to acuity may enhance noise levels. This single-center study investigated the impact of reorganization of neonatal intensive care unit by implementing clinical microsystems in a Level III NICU on environmental noise. This prospective study measured 24-h noise levels over a period of 6 months during pre- and post-implementation of microsystems cohorting infants of similar acuity. Comparative analyses of the mixed acuity (i.e., before) and the cohorting (i.e., after) model were performed by creating daily profiles from continuous noise level measurements and calculating the length of exposure to predefined noise levels. Compared to baseline daytime measurements, noise levels were 3-6 dBA higher during physician handover. Noise levels were 2-3 dBA lower on weekends and 3-4 dBA lower at night, independent of the organizational model. The introduction of clinical microsystems slightly increased average noise levels for high-acuity pods (A and B) but produced a much more substantial decrease for low-acuity pods (E), leading to an overall reduction in unit-wide noise levels.    Conclusion: Our data show that noise levels are more driven by human behavior than by technical devices. Implementation of microsystems may help to reduce noise exposure in the lower acuity pods in a NICU. What is Known: • Excessive noise levels can lead to adverse effects on the health and development of premature infants and other critically ill newborns. • The reorganization of the neonatal intensive care unit following the clinical microsystems principles might improve quality of care but also affect noise exposure of staff and patients. What is New: • The transition from a mixed -acuity to cohorting model is associated with an overall reduction in noise levels, particularly in low-acuity pods requiring less nursing care. • Nevertheless, baseline noise levels in both models exceeded the standard permissible limits.

Nutrition of the preterm infant with persistent ductus arteriosus: existing evidence and practical implications.

The persistence of a patent ductus arteriosus (PDA) is a common condition in preterm infants with a prevalence inversely proportional to gestational age. PDA is associated with mild-to-severe gastrointestinal complications such as feeding intolerance, gastrointestinal perforation, and necrotizing enterocolitis, which represent a major challenge for the nutritional management in preterm infants. In this context, the Section on Nutrition, Gastroenterology and Metabolism and the Circulation Section of the European Society for Pediatric Research have joined forces to review the current knowledge on nutritional issues related to PDA in preterm infants. The aim of the narrative review is to discuss the clinical implications for nutritional practice. Because there is little literature on postnatal nutrition and PDA in preterm infants, further research with well-designed studies on this topic is urgently needed. Guidelines should also be developed to clearly define the implementation and course of enteral nutrition and the target nutritional intake before, during, and after pharmacologic or surgical treatment of PDA, when indicated. IMPACT: Persistent ductus arteriosus (PDA) is associated with gastrointestinal complications such as feeding intolerance, gastrointestinal perforation, and necrotizing enterocolitis, which pose a major challenge to the nutritional management of preterm infants. In PDA infants, fluid restriction may lead to inadequate nutrient intake, which may negatively affect postnatal growth and long-term health. The presence of PDA does not appear to significantly affect mesenteric blood flow and splanchnic oxygenation after enteral feedings. Initiation or maintenance of enteral nutrition can be recommended in infants with PDA.

Make Bayley III Scores Comparable between United States and German Norms-Development of Conversion Equations.

AIM: Bayley Scales of Infant and Toddler Development (Bayley-III) determines scaled scores and converts these into composite scores. It was shown that applying the German and the U.S. manual leads to different results. This study aims to systematically analyze the differences between the U.S. and German Bayley-III version and to develop conversion equations. METHODS: This simulation study generated a dataset of pairs of U.S. and German Bayley-III composite scores (cognitive: n = 4,416, language: n = 240,000, motor: n = 314,000) by converting the same number of achievable tasks for 48 age groups. Bland-Altman plot and regression analyses were performed to develop conversion equations for all age groups. RESULTS: German and US Bayley-III scores demonstrate distinct slope and interception for cognitive, language, and motor composite scores. Lower developmental performance leads to higher composite scores with U.S. norms compared with German norms (up to 15 points). These differences varied between age groups. With newly developed conversion equations, the results can be converted (R 2 > 0.98). INTERPRETATION: This study confirms systematic differences between U.S. and German Bayley test results due to different reference cohorts. Our data consider the full age range and add conversion equations. These findings need to be acknowledged when comparing Bayley Scores internationally.

Enteral Nutrition in Preterm Infants (2022): A Position Paper From the ESPGHAN Committee on Nutrition and Invited Experts.

OBJECTIVES: To review the current literature and develop consensus conclusions and recommendations on nutrient intakes and nutritional practice in preterm infants with birthweight <1800 g. METHODS: The European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Committee of Nutrition (CoN) led a process that included CoN members and invited experts. Invited experts with specific expertise were chosen to represent as broad a geographical spread as possible. A list of topics was developed, and individual leads were assigned to topics along with other members, who reviewed the current literature. A single face-to-face meeting was held in February 2020. Provisional conclusions and recommendations were developed between 2020 and 2021, and these were voted on electronically by all members of the working group between 2021 and 2022. Where >90% consensus was not achieved, online discussion meetings were held, along with further voting until agreement was reached. RESULTS: In general, there is a lack of strong evidence for most nutrients and topics. The summary paper is supported by additional supplementary digital content that provide a fuller explanation of the literature and relevant physiology: introduction and overview; human milk reference data; intakes of water, protein, energy, lipid, carbohydrate, electrolytes, minerals, trace elements, water soluble vitamins, and fat soluble vitamins; feeding mode including mineral enteral feeding, feed advancement, management of gastric residuals, gastric tube placement and bolus or continuous feeding; growth; breastmilk buccal colostrum, donor human milk, and risks of cytomegalovirus infection; hydrolyzed protein and osmolality; supplemental bionutrients; and use of breastmilk fortifier. CONCLUSIONS: We provide updated ESPGHAN CoN consensus-based conclusions and recommendations on nutrient intakes and nutritional management for preterm infants.

[Operating models and organizational structures: opportunities and challenges for human milk banking in Germany]. / Versorgungsstrukturen und Betreibermodelle: Chancen und Herausforderungen des Frauenmilchbankwesens in Deutschland.

BACKGROUND: Donor human milk is the recommended alternative for feeding preterm infants if mother's own milk is unavailable. Human milk banks collect, screen, store and distribute donated human milk according to pre-specified standard operating procedures to premature infants without mothers own milk. AIM: Herein we characterize current operating models and the structural organisation of German milk bank institutions. The analysis of current and future opportunities and challenges may support the development of a comprehensive donor milk service within Germany. MATERIAL AND METHODS: Summary of the panel discussion entitled "Operating models and organizational structures: opportunities and risks for donor human milk bank in Germany" during the 3rd Scientific Symposium of the German Human Milk Bank Initiative (FMBI), November 25th to 26th 2022, in Nuremberg, Germany. RESULTS AND DISCUSSION: Differing operator models may facilitate the use of donor human milk by incorporating unique site-specific factors, pre-existing infrastructure, and individual needs. In addition to the establishment of milk banks serving single neonatal units, high-capacity milk banks should be enabled to provide donor human milk using several hub-and-spoke systems. This may create a nationwide network for a sustainable human milk supply for preterm infants that is based on qualified breastfeeding and lactation support.

Metabolic-endocrine disruption due to preterm birth impacts growth, body composition, and neonatal outcome.

Despite optimized nutrition, preterm-born infants grow slowly and tend to over-accrete body fat. We hypothesize that the premature dissociation of the maternal-placental-fetal unit disrupts the maintenance of physiological endocrine function in the fetus, which has severe consequences for postnatal development. This review highlights the endocrine interactions of the maternal-placental-fetal unit and the early perinatal period in both preterm and term infants. We report on hormonal levels (including tissue, thyroid, adrenal, pancreatic, pituitary, and placental hormones) and nutritional supply and their impact on infant body composition. The data suggest that the premature dissociation of the maternal-placental-fetal unit leads to a clinical picture similar to panhypopituitarism. Further, we describe how the premature withdrawal of the maternal-placental unit, neonatal morbidities, and perinatal stress can cause differences in the levels of growth-promoting hormones, particularly insulin-like growth factors (IGF). In combination with the endocrine disruption that occurs following dissociation of the maternal-placental-fetal unit, the premature adaptation to the extrauterine environment leads to early and fast accretion of fat mass in an immature body. In addition, we report on interventional studies that have aimed to compensate for hormonal deficiencies in infants born preterm through IGF therapy, resulting in improved neonatal morbidity and growth. IMPACT: Preterm birth prematurely dissociates the maternal-placental-fetal unit and disrupts the metabolic-endocrine maintenance of the immature fetus with serious consequences for growth, body composition, and neonatal outcomes. The preterm metabolic-endocrine disruption induces symptoms resembling anterior pituitary failure (panhypopituitarism) with low levels of IGF-1, excessive postnatal fat mass accretion, poor longitudinal growth, and failure to thrive. Appropriate gestational age-adapted nutrition alone seems insufficient for the achievement of optimal growth of preterm infants. Preliminary results from interventional studies show promising effects of early IGF-1 supplementation on postnatal development and neonatal outcomes.

[Process for the Implementation of Evidence-Based Parenteral Nutrition in German Perinatal Centres - Outcomes of a Multidisciplinary Network]. / Prozess zur Implementierung Evidenzbasierter Parenteraler Ernährung in Deutschen Perinatalzentren ­ Ergebnisse eines Multidisziplinären Netzwerks.

INTRODUCTION: Parenteral nutrition, usually indicated for preterm infants with a birthweight<1500 g and sick newborns, enables the supply with critical nutrients. As a high degree of therapy safety is required, a European guideline provides recommendations for safe therapy procedures. The present project aimed to evaluate the implementation of the European guideline in German perinatal centers and to identify possible barriers that impede its implementation. A further goal was to develop solution approaches to overcome possible barriers. METHODS AND RESULTS: A multidisciplinary cooperation conducted an online survey questioning the current implementation procedures of the European guideline among pediatricians and hospital pharmacists. Results show barriers in the provisioning process of parenteral nutrition that hinder a guideline-compliant implementation in practice. Based on results of this survey, an expert network developed an interactive toolkit with simplified guideline recommendations, guideline-compliant advice for practice, best-practice examples, forms, and handouts. It seeks to encourage critical reflection of routine processes and provides concrete solutions to overcome barriers in practice. CONCLUSION: The current procedures related to parenteral nutrition deviate from guideline recommendations. The developed toolkit provides practice-oriented support aiming to enhance the guideline-compliant implementation of parenteral nutrition in perinatal centers.

Necrotizing enterocolitis and mortality after transfusion of ABO non-identical blood.

BACKGROUND: The relationship between ABO non-identical transfusion and the outcomes of necrotizing enterocolitis (NEC), and all-cause mortality in very-low birth weight (VLBW) neonates receiving red blood cell transfusion is unknown. STUDY DESIGN AND METHODS: A retrospective multicenter cohort study was conducted in VLBW neonates in neonatal intensive care units between 2004 and 2016. VLBW (≤1500 grams) neonates were followed until discharge or in-hospital death. The primary exposure was ABO group. Secondary exposures included platelet count, plasma transfusions, and maternal ABO group. Outcome measures were NEC (defined as Bell stage ≥ 2) and all-cause mortality. Time-dependent Cox regression models with competing risks were used to investigate factors associated with NEC and mortality. RESULTS: Thousand and sixteen neonates were included with 10.8% developing NEC (n = 110) and 14.1% mortality (n = 143). Platelet count (hazard ratio [HR] = 0.995; 95% confidence interval [CI]: 0.922-0.998) and number of plasma transfusions (HR = 2.908; 95% CI:1.265-6.682) were associated with NEC, while ABO group (non-O vs. O) was not (HR = 0.761; 95% CI: 0.393-1.471). Higher all-cause mortality occurred in neonates without NEC who were non-O compared with O (HR = 17.5; 95% CI: 1.784-171.692), but not in neonates with NEC (HR = 1.112; 95% CI: 0.142-8.841). Plasma transfusion was associated with increased mortality in both groups. DISCUSSION: ABO non-identical transfusion was not associated with NEC or mortality in neonates with NEC. It was associated with increased mortality in neonates without NEC. As many neonatal intensive care units transfuse only O group blood as routine practice, future trials are needed to investigate the association between this practice and neonatal mortality.

Targeting human milk fortification to improve very preterm infant growth and brain development: study protocol for Nourish, a single-center randomized, controlled clinical trial.

BACKGROUND: Human milk is recommended for very preterm infants, but its variable macronutrient content may contribute to undernutrition during a critical period in development. We hypothesize that individually targeted human milk fortification is more effective in meeting macronutrient requirements than the current standard of care. METHODS: We designed a single-center randomized, controlled trial enrolling 130 infants born < 31 completed weeks' gestation. Participants will receive fortified maternal and/or pasteurized donor milk but no formula. For participants in the intervention group, milk will be individually fortified with protein and fat modulars to achieve target levels based on daily point-of-care milk analysis with mid-infrared spectroscopy, in addition to standard fortification. The study diet will continue through 36 weeks' postmenstrual age (PMA). Clinical staff and parents will be masked to study group. Primary outcomes include: 1) body length and lean body mass by air displacement plethysmography at 36 weeks' PMA; 2) quantitative magnetic resonance imaging-based measures of brain size and microstructure at term equivalent age; and 3) Bayley-IV scales at 2 years' corrected age. DISCUSSION: We expect this trial to provide important data regarding the effectiveness of individually targeted human milk fortification in the neonatal intensive care unit (NICU). TRIAL REGISTRATION: NCT03977259 , registered 6 June, 2019.

[Is the Quality Guideline of Care Delivery of Preterm and Mature Infants (QFR-RL) of the Federal Joint Committee (G-BA) a Quality Risk? - An Analysis of the Fulfillment Rate and the Consequences for Care Delivery to Other IC Patients and Imminent Premature Infants at a Regional Network of Perinatal Centers]. / Qualitätssicherungsrichtlinie Früh- und Reifgeborene des Gemeinsamen Bundesausschusses als Qualitätsrisiko?

BACKGROUND: The quality guideline for care delivery to preterm and mature infants (QFR-RL) places high demands on perinatal centers. In this analysis, the degree of fulfillment was determined. Additionally, care delivery to further patient groups and sufficient nursing staff capacity for care delivery to imminent preterm infants (FG) were evaluated. METHODS: A network of 4 perinatal centers (level 1) with about 10,000 births per year supplied the data on the ratio of 1:1/1:2-care infants, patients per nurse, and nursing staff capacity. This data was statistically evaluated by center, shift, and week day over a period of 5 months for compliance with QFR-RL and DGPM recommendations. Furthermore, imminent preterm infants were recorded and compared with available nursing staff capacity. RESULTS: In total, the QFR-RL was fulfilled in 88% of shifts (n=1,584). Only one center reached the required 95%. The degree of fulfillment and the number of staff nurses declined from late to night shifts (p<0.001). The ratio of 1:1-care infants was significantly higher when demands were not fulfilled (p<0.001). Only 14.1% of imminent preterm infants could have been attended in accordance with the QFR-RL. CONCLUSION: 1:1 care as well as lower nurse staffing in late and night shifts lead to non-fulfillment of requirements and poorer care delivery to other intensive care patients. This was also reflected in the lower degree of fulfillment of DGPM recommendations. Sufficient nursing staff capacity was rare with the consequence that it was almost impossible to deliver care to imminent preterm infants per the guideline.

Gastric Residual Volume in Feeding Advancement in Preterm Infants (GRIP Study): A Randomized Trial.

OBJECTIVE: To evaluate the effect of not relying on prefeeding gastric residual volumes to guide feeding advancement on the time to reach full feeding volumes in preterm infants, compared with routine measurement of gastric residual volumes. We hypothesized that not measuring prefeeding gastric residual volumes can shorten the time to reach full feeds. STUDY DESIGN: In this single-center, randomized, controlled trial, we included gavage fed preterm infants with birth weights (BW) 1500-2000 g who were enrolled within 48 hours of birth. Exclusion criteria were major congenital malformations, asphyxia, and BW below the third percentile. In the study group, the gastric residual volume was measured only in the presence of bloody aspirates, vomiting, or an abnormal abdominal examination. In the control group, gastric residual volume was assessed routinely, and feeding advancement was based on the gastric residual volume. The primary outcome was the time to reach feeding volumes of 120 mL/kg per day. Secondary outcomes were time to regain BW, episodes of feeding interruptions, sepsis, and necrotizing enterocolitis. RESULTS: Eighty-seven infants were enrolled. There were no differences between the study and control groups with respect to time to reach full feeds (6 days [95% CI, 5.5-6.5] vs 5 days [95% CI, 4.5-5.5]; P = .82), time to regain BW, episodes of feeding interruptions, or sepsis. Two infants in the control group developed necrotizing enterocolitis. CONCLUSIONS: Avoiding routine assessment of gastric residual volume before feeding advancement did not shorten the time to reach full feeds in preterm infants with BW between 1500 and 2000 g. TRIAL REGISTRATION: Clinicaltrials.gov: NCT01337622.

Infrared analyzers for breast milk analysis: fat levels can influence the accuracy of protein measurements.

BACKGROUND: Currently, there is a growing interest in lacto-engineering in the neonatal intensive care unit, using infrared milk analyzers to rapidly measure the macronutrient content in breast milk before processing and feeding it to preterm infants. However, there is an overlap in the spectral information of different macronutrients, so they can potentially impact the robustness of the measurement. In this study, we investigate whether the measurement of protein is dependent on the levels of fat present while using an infrared milk analyzer. METHODS: Breast milk samples (n=25) were measured for fat and protein content before and after being completely defatted by centrifugation, using chemical reference methods and near-infrared milk analyzer (Unity SpectraStar) with two different calibration algorithms provided by the manufacturer (released 2009 and 2015). RESULTS: While the protein content remained unchanged, as measured by elemental analysis, measurements by infrared milk analyzer show a difference in protein measurements dependent on fat content; high fat content can lead to falsely high protein content. This difference is less pronounced when measured using the more recent calibration algorithm. CONCLUSIONS: Milk analyzer users must be cautious of their devices' measurements, especially if they are changing the matrix of breast milk using more advanced lacto-engineering.

Survey of noninvasive respiratory support practices in Canadian neonatal intensive care units.

AIM: To evaluate practice variation with respect to noninvasive respiratory support (NRS) use across Canadian neonatal intensive care units (NICUs). METHODS: A web-based survey was sent to all site investigators of the 30 level 3 NICUs participating in the Canadian Neonatal Network. The survey inquired about the use of five commonly described NRS modes. In addition, the presence and adherence to local guidelines were ascertained. Descriptive analyses were performed to identify variations in practice. RESULTS: In total, 28 (93%) of the 30 tertiary NICUs responded to the survey. Continuous positive airway pressure (CPAP) was employed universally (100%). High-flow nasal cannula (HFNC) was used in 89% of NICUs, biphasic CPAP in 79% and nasal intermittent positive pressure ventilation (NIPPV) in 54%, and nasal high-frequency ventilation was used in 18% of units. Only 61% of all NRS use was guided by local policies, with the lowest being for HFNC (36%). There was a wide range of settings employed and interfaces used for all NRS modes. CONCLUSION: There are significant practice variations in NRS use across Canadian NICUs. Further research is needed to evaluate the significance in relation to pulmonary outcomes to determine optimal NRS strategies.

Introduction of microsystems in a level 3 neonatal intensive care unit-an interprofessional approach.

BACKGROUND: Growth of neonatal intensive care units in number and size has raised questions towards ability to maintain continuity and quality of care. Structural organization of intensive care units is known as a key element for maintaining the quality of care of these fragile patients. The reconstruction of megaunits of intensive care to smaller care units within a single operational service might help with provision of safe and effective care. METHODS/DESIGN: The clinical team and patient distribution lay out, admission and discharge criteria and interdisciplinary round model was reorganized to follow the microstructure philosophy. A working group met weekly to formulate the implementation planning, to review the adaptation and adjustment process and to ascertain the quality of implementation following the initiation of the microsystem model. DISCUSSION: In depth examination of microsystem model of care in this study, provides systematic evaluation of this model on variable aspects of health care. The individual projects of this trial can be source of solid evidence for guidance of future decisions on optimized model of care for the critically ill newborns. TRIAL REGISTRATION: ClinicalTrial.gov, NCT02912780 . Retrospectively registered on 22 September 2016.

Physiological adjustment to postnatal growth trajectories in healthy preterm infants.

BACKGROUND: International guidelines suggest that growth of preterm infants should match intrauterine rates. However, the trajectory for extrauterine growth may deviate from the birth percentile due to an irreversible, physiological loss of extracellular fluid during postnatal adaptation to extrauterine conditions. To which "new" physiological growth trajectory preterm infants should adjust to after completed postnatal adaptation is unknown. This study analyzes the postnatal growth trajectories of healthy preterm infants using prospective criteria defining minimal support, as a model for physiological adaptation. METHODS: International, multi-center, longitudinal, observational study at five neonatal intensive care units (NICUs). Daily weights until day of life (DoL) 21 of infants with undisturbed postnatal adaptation were analyzed (gestational ages: (i) 25-29 wk, (ii) 30-34 wk). RESULTS: 981 out of 3,703 admitted infants included. Maximum weight loss was 11% (i) and 7% (ii) by DoL 5, birth weight regained by DoL 15 (i) and 13 (ii). Infants transitioned to growth trajectories parallel to Fenton chart percentiles, 0.8 z-scores below their birth percentiles. The new trajectory after completed postnatal adaptation could be predicted for DoL 21 with R(2) = 0.96. CONCLUSION: This study provides a robust estimate for physiological growth trajectories of infants after undisturbed postnatal adaptation. In the future, the concept of a target postnatal trajectory during NICU care may be useful.

Effect of Supplemental Donor Human Milk Compared With Preterm Formula on Neurodevelopment of Very Low-Birth-Weight Infants at 18 Months: A Randomized Clinical Trial.

Importance: For many very low-birth-weight (VLBW) infants, there is insufficient mother's milk, and a supplement of pasteurized donor human milk or preterm formula is required. Awareness of the benefits of mother's milk has led to an increase in use of donor milk, despite limited data evaluating its efficacy. Objective: To determine if nutrient-enriched donor milk compared with formula, as a supplement to mother's milk, reduces neonatal morbidity, supports growth, and improves neurodevelopment in VLBW infants. Design, Setting, and Participants: In this pragmatic, double-blind, randomized trial, VLBW infants were recruited from 4 neonatal units in Ontario, Canada, within 96 hours of birth between October 2010 and December 2012. Follow-up was completed in July 2015. Interventions: Infants were fed either donor milk or formula for 90 days or to discharge when mother's milk was unavailable. Main Outcomes and Measures: The primary outcome was the cognitive composite score on the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) at 18 months' corrected age (standardized mean, 100 [SD, 15]; minimal clinically important difference, 5 points). Secondary outcomes included Bayley-III language and motor composite scores, growth, and a dichotomous mortality and morbidity index. Results: Of 840 eligible infants, 363 (43.2%) were randomized (181 to donor milk and 182 to preterm formula); of survivors, 299 (92%) had neurodevelopment assessed. Mean birth weight and gestational age of infants was 996 (SD, 272) g and 27.7 (2.6) weeks, respectively, and 195 (53.7%) were male. No statistically significant differences in mean Bayley-III cognitive composite score (adjusted scores, 92.9 in donor milk group vs 94.5 in formula group; fully adjusted mean difference, -2.0 [95% CI, -5.8 to 1.8]), language composite score (adjusted scores, 87.3 in donor milk group vs 90.3 in formula group; fully adjusted mean difference, -3.1 [95% CI, -7.5 to 1.3]), or motor composite score (adjusted scores, 91.8 in donor milk group vs 94.0 in formula group; fully adjusted mean difference, -3.7 [95% CI, -7.4 to 0.09]) were observed between groups. There was no statistically significant difference in infants positive for the mortality and morbidity index (43% in donor milk group, 40% in formula group) or changes in growth z scores. Conclusions and Relevance: Among VLBW infants, use of supplemental donor milk compared with formula did not improve neurodevelopment at 18 months' corrected age. If donor milk is used in settings with high provision of mother's milk, this outcome should not be considered a treatment goal. Trial Registration: isrctn.org Identifier: ISRCTN35317141.

Impact of interprofessional education on noninvasive ventilation in a tertiary neonatal intensive care unit.

OBJECTIVE: To evaluate the impact and effectiveness of an experiential interprofessional education workshop on noninvasive ventilation (NIV) in the setting of a neonatal intensive care unit. METHODS: In the present cross-sectional study, a full-day workshop, consisting of didactic and hands-on components, was developed to assess knowledge and perceptions, and to disseminate the latest evidence and practical aspects of NIV use. All health care professionals (HCPs) were asked to participate. Pre- and post-participation questionnaires and knowledge tests were used to assess the effectiveness of knowledge transfer, and to seek participants' reflections on the utility of the workshop. RESULTS: Among 214 participants, 206 (96%) and 195 (91%) completed the pre- and post-participation questionnaires, respectively. The majority agreed (14%) or strongly agreed (75%) that NIV education was important for their role. Participants scored their perceived comfort with NIV following the workshop highly (median 5 [interquartile range (IQR) 1]) on a five-point Likert scale and 96% would recommend it to a colleague. Median knowledge scores on NIV, assessed as percent correct responses, increased from 74% (IQR 16) to 86% (IQR 11) (P<0.05). CONCLUSIONS: A focused, context-specific workshop helped improve understanding and comfort among HCPs while reducing misconceptions about NIV. Further research to assess optimal delivery of NIV education and impact on patient outcomes is required.

Les effets d'une formation interprofessionnelle sur la ventilation non invasive dans une unité de soins intensifs néonatals de niveau tertiaire. OBJECTIF: Évaluer les effets et l'efficacité d'un atelier expérimental de formation interprofessionnelle sur la ventilation non invasive (VNI) dans une unité de soins intensifs néonatals. MÉTHODOLOGIE: Dans la présente étude transversale, les chercheurs ont créé un atelier d'une journée comportant des volets magistraux et pratiques pour évaluer les connaissances et les perceptions et pour faire connaître les données probantes les plus récentes et les aspects pratiques de la VNI. Ils ont invité tous les professionnels de la santé (PdS) à y participer. Ils ont utilisé des questionnaires avant et après la participation et des tests de connaissances pour évaluer l'efficacité de l'application du savoir et pour obtenir les réflexions des participants sur l'utilité de l'atelier. RÉSULTATS: Parmi les 214 participants, 206 (96 %) et 195 (91 %) ont rempli le questionnaire avant et après la participation, respectivement. La majorité étaient d'accord (14 %) ou tout à fait d'accord (75 %) pour affirmer que la formation sur la VNI était importante dans leur rôle. Les participants avaient une perception élevée de leur aisance à l'égard de la VNI après la formation (médiane 5 [plage interquartile (PIQ) 1]) sur une échelle de Likert de cinq points, et 96 % l'auraient recommandée à un collègue. Les indices de connaissances médians sur la VNI, évalués selon le pourcentage de bonnes réponses, sont passés de 74 % (PIQ 16) à 86 % (PIQ 11) (P<0,05). CONCLUSIONS: Un atelier ciblé et adapté au milieu a contribué à accroître la compréhension et l'aisance des PdS tout en réduisant les idées fausses quant à la VNI. D'autres recherches s'imposent pour évaluer la prestation optimale de la formation sur la VNI et les effets sur les résultats cliniques des patients.

Microbiota at Multiple Body Sites during Pregnancy in a Rural Tanzanian Population and Effects of Moringa-Supplemented Probiotic Yogurt.

The nutritional status of pregnant women is vital for healthy outcomes and is a concern for a large proportion of the world's population. The role of the microbiota in pregnancy and nutrition is a promising new area of study with potential health ramifications. In many African countries, maternal and infant death and morbidity are associated with malnutrition. Here, we assess the influence of probiotic yogurt containing Lactobacillus rhamnosus GR-1, supplemented with Moringa plant as a source of micronutrients, on the health and oral, gut, vaginal, and milk microbiotas of 56 pregnant women in Tanzania. In an open-label study design, 26 subjects received yogurt daily, and 30 were untreated during the last two trimesters and for 1 month after birth. Samples were analyzed using 16S rRNA gene sequencing, and dietary recalls were recorded. Women initially categorized as nourished or undernourished consumed similar calories and macronutrients, which may explain why there was no difference in the microbiota at any body site. Consumption of yogurt increased the relative abundance of Bifidobacterium and decreased Enterobacteriaceae in the newborn feces but had no effect on the mother's microbiota at any body site. The microbiota of the oral cavity and GI tract remained stable over pregnancy, but the vaginal microbiota showed a significant increase in diversity leading up to and after birth. In summary, daily micronutrient-supplemented probiotic yogurt provides a safe, affordable food for pregnant women in rural Tanzania, and the resultant improvement in the gut microbial profile of infants is worthy of further study.

Challenges in breast milk fortification for preterm infants.

PURPOSE OF REVIEW: To outline new evidence published from 2013 to 2014 about breast milk fortification in preterm infants. RECENT FINDINGS: Breast milk is the feeding choice for preterm infants because of its immunoprotective properties. However, breast milk's nutrient content is not sufficient for preterm infants, and interindividual variation is high. The variation challenges standard fortification, which assumes a standard breast milk composition. Two new fortification strategies (adjustable fortification and target fortification) optimize macronutrient intake and improve growth. Adjustable fortification uses blood urea nitrogen levels to adjust fortifier strength. Target fortification analyzes breast milk and fortifies macronutrients individually to achieve targeted intake. Its feasibility is shown in clinical routine. Current breast milk analyzers used for target fortification achieve acceptable precision for protein and fat but not for lactose and energy. Evidence of benefits for postdischarge breast milk fortification is lacking. Eliminating cow's milk products and feeding exclusively breast milk may decrease the occurrence of feeding intolerance and necrotizing enterocolitis. To facilitate exclusively breast milk diets, a collaboration of prenatal, nutrition and lactation stakeholders is key. Fortification increases osmolality; however, safety cutoffs to prevent necrotizing enterocolitis are unclear. There is also new evidence that composition and structure of various macronutrients and micronutrients affect growth and development, and might play a role in future fortification concepts. SUMMARY: Recent research focuses on the variability of breast milk composition, its impact on postnatal growth patterns and the usefulness of target fortification. As well, diets exclusively composed of human milk are a promising approach to improve feeding tolerance. For safe fortification, osmolality cutoff levels are needed.

Target fortification of breast milk: levels of fat, protein or lactose are not related.

AIM: Target fortification (TFO) of breast milk has the potential to improve the nutritional outcomes of preterm infants. However, the primary logistic constraint in introducing TFO is analysers that rapidly and accurately analyse macronutrients (fat, protein and lactose). In this prospective observational study, we aim to evaluate whether the levels of fat, protein and carbohydrate could be predicted from one key macronutrient. METHODS: Macronutrient components were measured in 543 breast milk samples using validated chemical micro-methods. Correlation analysis for fat versus protein, fat versus lactose and lactose versus protein was computed using Pearson's correlation. RESULTS: The concentration of the macronutrients ranged from 0.7 to 10.3 g/100 mL (3.7 ± 1.2, mean ± SD) for fat, 0.7 to 3.2 g/100 mL (1.3 ± 0.3) for protein and 4.0 to 8.8 g/100 mL (5.8 ± 0.7) for lactose, respectively. There was no correlation between the three macronutrients. CONCLUSION: This lack of correlation underlines the importance of routine and accurate analysis of all three macronutrients in breast milk prior to TFO.
