Background Data on how baseline characteristics, acuity, morbidity, and nutrition work in combination to affect the growth of very-low-birth-weight (VLBW, <1500 g) infants are limited. Objective We aimed to determine factors associated with in-hospital weight, length, and head circumference (HC) trajectories of VLBW infants. Methods VLBW infants (n = 316) from the GTA-DoMINO trial were included. Linear mixed-effects models assessed relations of baseline characteristics, acuity (at birth, across hospitalization), major morbidities, and nutrition (enteral feeding type, macronutrient/energy intakes) with changes in anthropometrics over hospitalization (days 1–8, 9–29, 30–75). Results Specific factors and the strength of their associations with growth depended on in-hospital time interval. Small-for-gestational-age infants experienced weight gain (4.3 g · kg−1 · d−1; 95% CI: 2.0, 6.5 g · kg−1 · d−1) during days 1–8, versus weight loss (−4.6 g · kg−1 · d−1; 95% CI: −5.6, −3.7 g · kg−1 · d−1) among appropriate-for-gestational-age infants (P < 0.001). Positive-pressure ventilation (versus oxygen/room air) was associated with slower weight (−1.8 g · kg−1 · d−1) and HC (−0.25 cm/wk) gain during days 9–29 (P < 0.001). Morbidities were negatively associated with growth after days 1–8, with patent ductus arteriosus (PDA) showing negative associations with weight (−2.7 g · kg−1 · d−1), length (−0.11 cm/wk), and HC (−0.21 cm/wk) gain during days 9–29 (P < 0.001). Macronutrient/energy intakes were associated with weight across hospitalization (P ≤ 0.01), with greater weight gain (1.3–3.0 g · kg−1 · d−1) among infants achieving macronutrient/energy recommendations during days 9–29 and 30–75. Macronutrient/energy intakes were associated with HC during the first month (P = 0.013–0.003), with greater HC gain (0.07–0.12 cm/wk) among infants achieving protein, lipid, and energy recommendations during days 9–29. Conclusions Baseline characteristics, acuity, morbidity, and nutrition factors were independently associated with VLBW infant growth. A focus on achieving macronutrient/energy recommendations and improving nutrient delivery to PDA-diagnosed infants may yield improvements to their growth. This trial was registered at www.isrctn.com as ISRCTN35317141.
Despite the introduction of more aggressive early feeding guidelines and improved energy and nutrient intakes compared with literature values, many VLBW infants remain below recommended nutrition goals in the first week.
Morbidity is associated with a decreased likelihood of achieving lipid and consequently energy recommendations. This and the decline in protein intakes after the early neonatal period require further investigation to ensure optimal nutrition in this vulnerable population.
Background Bovine milk-based fortifiers (BMBF) have been standard of care for nutrient fortification of feeds for very low birthweight (VLBW) infants, however there is increasing use of human milk-based fortifiers (HMBF) in neonatal care despite additional costs and limited supporting data. No randomized clinical trial has followed infants fed these fortifiers after initial hospitalization. Objective To compare neurodevelopment in infants born weighing <1250 g fed mother's milk with supplemental donor milk and either a HMBF or BMBF. Methods This is a follow-up of a completed pragmatic, triple-blind, parallel randomized clinical trial conducted in Southern Ontario between August 2014 and March 2016 (NCT02137473) with feeding tolerance as the primary outcome. Infants weighing <1250 g at birth were block randomized by an online third-party service to receive either HMBF (n = 64) or BMBF (n = 63) added to mother's milk with supplemental donor milk during hospitalization. Neurodevelopment was assessed at 18-months corrected age using the Bayley Scales of Infant and Toddler Development, Third Edition. Follow-up was completed October 2017. Results Of the 127 infants randomized, 109 returned for neurodevelopmental assessment. No statistically significant differences between fortifiers were identified for cognitive composite scores (adjusted scores 94.7 in the HMBF group and 95.9 in the BMBF group; fully adjusted mean difference, −1.1 [95% CI: −6.5 to 4.4]), language composite scores (adjusted scores 92.4 in the HMBF group and 93.1 in the BMBF; fully adjusted mean difference, −1.2 [−7.5 to 5.1]), or motor composite scores (adjusted scores 95.6 in the HMBF group and 97.7 in the BMBF; fully adjusted mean difference, −1.1 [−6.3 to 4.2]). There was no difference in the proportion of participants that died or had neurodevelopmental impairment or disability between groups. Conclusions Providing HMBF compared to BMBF does not improve neurodevelopment scores at 18-months corrected age in infants born <1250 g otherwise fed a human milk diet.

Infants born at very low birth weight (<1500 g) are vulnerable to nutritional deficits during their first postnatal month, which are associated with poor neurodevelopmental outcomes. Despite this knowledge, the impact of early postnatal nutrition on white matter microstructure in children born very low birth weight has not been investigated. In this prospective cohort study, we employed a whole-brain approach to investigate associations between precise estimates of nutrient intake within the first postnatal month with white matter microstructure at 5 years of age. Detailed information about breastmilk, macronutrient and energy intakes during this period were prospectively recorded for all participants. Multi-shell diffusion and T1-weighted MRIs were acquired in 41 children (21 males; mean scan age: 5.75 ± 0.22 years; mean birth weight: 1028.6 ± 256.8 g.). The diffusion tensor imaging and neurite orientation dispersion and density imaging models were used to obtain maps of fractional anisotropy, radial diffusivity, orientation dispersion and neurite density indices. Tract-Based Spatial Statistics was used to test associations between metrics of white matter microstructure with breastmilk, macronutrient (protein, lipids and carbohydrate) and energy intake. Associations between white matter microstructure and cognitive outcomes were also examined. Compared to children who did not meet enteral feeding recommendations, those who achieved enteral protein, lipid and energy recommendations during the first postnatal month showed improved white matter maturation at 5 years. Thus, among the macronutrients, greater protein intake contributed to the beneficial effect of nutrition, showing widespread increases in fractional anisotropy and reductions in radial diffusivity. No significant associations were found between white matter metrics with breastmilk or carbohydrate intake. Voxel-wise analyses with cognitive outcomes revealed significant associations between higher fractional anisotropy and neurite density index with higher processing speed scores. Lower radial diffusivity and orientation dispersion index were also associated with improved processing speed. Our findings support the long-term impacts of early nutrition on white matter microstructure, which in turn is related to cognitive outcomes. These results provide strong support for early postnatal nutritional intervention as a promising strategy to improve long-term cognitive outcomes of infants born at very low birth weight.
We present a case of hemophagocytic lymphohistiocytosis (HLH) in a previously healthy 30-year-old woman. The patient presented with features consistent with HLH: persistent fever, neurological abnormalities, lymphadenopathy, anaemia, leucopoenia and markedly elevated serum lactate dehydrogenase and ferritin levels. Diagnosis was delayed for approximately 1 month beyond presentation. Once initiated on treatment, the patient rapidly improved and was discharged from the intensive care unit and subsequently sent home. Unfortunately, she succumbed to progressive HLH 5 months after her initial presentation. This case highlights key clinical features associated with HLH to help prevent late diagnosis as delayed treatment may lead to irreversible multi-organ failure and/or death.
The aim of our study was to design and evaluate the impact on informational satisfaction of a combined story and fact-based educational booklet designed for patients with multiple brain metastases. Phase A evaluated the preference of participants for combined, fact, or story-based writing style. Based on these results, a resource was developed using a combined story and fact-based approach. Patients with newly diagnosed brain metastases and their caregivers read the booklet. Satisfaction was evaluated using the Information Satisfaction Questionnaire and Client Satisfaction Questionnaire. Anxiety was evaluated before and after reading using the State Trait Anxiety Inventory. Ninety-one patients participated in this study. In Phase A, 51% of patients expressed a preference for the combined story and fact-based approach. In phase B, participants expressed high satisfaction for both the informational content and the overall satisfaction towards the pamphlet. The level of anxiety before reading the booklet was lower for caregivers than patients. Anxiety score was increased in the caregiver group after reading the booklet. This was unchanged in the patient group. Both patients and caregivers endorsed the resource. The increase in anxiety in caregivers suggests the tool has been effective in conveying serious prognostic implications.
