Abstract
BACKGROUND The olfactory bulb has a key role for nasal delivery of drugs to the brain by its access from the nasal mucosa and its connection to the subventricular zone. The aim of this study was to investigate the neuromodulatory capacity of human milk of premature infants on the olfactory bulb. METHODS Olfactory bulbs from P1 mice were embedded in a collagen I gel and incubated with DMEM supplemented with the aqueous phase of human colostrum (Col) of five mothers after very preterm birth, mature milk (Mat) of the same mothers or without supplement (Ctrl). After 7 days, the neurite outgrowth was quantified. Proteome analysis of the milk samples was performed using unlabeled mass spectrometry. RESULTS Outgrowth increased significantly in bulbs exposed to Col but not when exposed to Mat. Mass spectrometry revealed profound differences in the proteome of Col versus Mat. Among 21 upregulated proteins in Col were proteins involved in neurite outgrowth, axon guidance, neuromodulation and longevity. CONCLUSIONS A high bioactivity of human preterm colostrum on murine neonatal neurogenic tissue is demonstrated to be associated with a proteome profoundly differing from mature milk. IMPACT The hypothesis has been raised that neonatal brain damage in a preterm infant could potentially be ameliorated by intranasal application of maternal breast milk. In an in-vitro model using neonatal murine olfactory bulb explants a significant stimulatory effect by human preterm colostrum is observed. Proteomics reveals upregulated neuroactive proteins in human colostrum compared to mature milk. A confirmation of this exploratory study would indicate that preterm colostrum stimulates neurogenic tissue. Early intranasal colostrum application might attenuate perinatal loss of neurogenic tissue thereby contributing to reducing complications such as cerebral palsy.

Front Neurol 2023; 13:993985. [PMID: 36742049 PMCID: PMC9889932 DOI: 10.3389/fneur.2022.993985] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 12/19/2022] [Indexed: 01/19/2023] Open
Abstract
Objective To investigate the protective effect of high-proportion breast milk feeding (>50%) on intraventricular hemorrhage (IVH) in very preterm infants (VPIs). Methods This was a retrospective secondary analysis of a prospective multi-center study, which included 604 VPIs from six hospitals in eastern China between September 2019 and December 2020. The 604 VPIs were divided into two groups according to whether IVH occurred. High-proportion breast milk feeding was defined as breast milk accounting for 51-100% of the total feeding amount both within 7 days and throughout the hospitalization. The IVH grades and the rate of high-proportion breast milk feeding were analyzed. Furthermore, to explore the relationship between high-proportion breast milk feeding and IVH grading, the VPIs' general information, perinatal factors, growth, and nutritional status during hospitalization, and related complications were compared between the two groups. Results High-proportion breast milk feeding was reported in 63.41% of the VPIs. Furthermore, IVH grades I-II and III-IV were noted in 39.73% (240/604) and 1.66% (10/604) of the VPIs, respectively. Univariate analysis revealed that IVH occurrence in VPIs is influenced by perinatal factors, invasive respiratory therapy, high-proportion breast milk feeding, start feeding with breast milk, the cumulative amount of early parenteral nutrition, postnatal complications, physical growth, and other factors (P < 0.05). After adjustments for gestational age, birth weight, and possible influencing factors through binary logistic regression analysis, the results revealed that high-proportion breast milk feeding and and start feeding with breast milk were associated with a lower total incidence of IVH. Further stratification showed that high-proportion breast milk feeding was associated with a lower incidence of grade I-II IVH. Similarly, after adjusting for the same factors, breast milk feeding >50% in the 1st week was associated with a decreased incidence of total IVH and further stratification showed that it was associated with a lower incidence of grade I-II IVH. Conclusion High-proportion breast milk feeding and breast milk feeding more than 50% of total intake during the 1st week might be protective factors for IVH grade I-II in VPIs, which further verified the neuroprotective effect of breast milk. In clinical practice, the construction of breast milk banks should be strengthened, breast milk feeding should be encouraged in neonatal intensive care units, and efforts should be made to increase breast milk feeding rates to improve the outcomes of VPIs.

Exclusive human milk diet reduces incidence of severe intraventricular hemorrhage in extremely low birth weight infants. J Perinatol 2021; 41:535-543. [PMID: 32999446 DOI: 10.1038/s41372-020-00834-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Revised: 08/25/2020] [Accepted: 09/18/2020] [Indexed: 12/19/2022]
Abstract
OBJECTIVE Compare the incidence of severe (grade III/IV) intraventricular hemorrhage (IVH) and/or periventricular leukomalacia (PVL) between two groups of ELBW infants based on diet until 34 weeks corrected gestational age (CGA): (1) Exclusive human milk (EHM)-mother's own and/or pasteurized donor human milk, human milk-derived fortifier, and oral care with colostrum/human milk vs. (2) non-EHM-bovine formula or mother's own milk with bovine-derived fortifier. STUDY DESIGN Retrospective observational study of two groups of ELBW infants based on diet until 34 weeks CGA. RESULT There were n = 306 infants, 127 EHM and 179 non-EHM. Demographics and morbidities were similar except higher antenatal steroids and NEC in EHM group. The rate of severe IVH/PVL was lower in EHM compared to non-EHM group (7 vs. 18%, p < 0.006). CONCLUSION EHM diet had an independent neuroprotective effect and was associated with decreased incidence of severe IVH/PVL, supporting the need of EHM in ELBW infants.

Association between serum levels of caspase-cleaved cytokeratin-18 and early mortality in patients with severe spontaneous intracerebral hemorrhage. BMC Neurosci 2018; 19:23. [PMID: 29661155 PMCID: PMC5902924 DOI: 10.1186/s12868-018-0424-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2017] [Accepted: 04/06/2018] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Apoptotic changes after cerebral hemorrhage in brain samples of humans have been found. Caspase-cleaved cytokeratin (CCCK)-18 could be detected in the bloodstream during apoptosis. Higher circulating CCCK-18 levels have been associated with 6-month mortality in patients with basal ganglia hemorrhage. The aim of our study was to determine whether there is an association between serum CCCK-18 levels and early mortality of spontaneous intracerebral hemorrhage (SIH) patients. We performed an observational, prospective and multicentre study. There were included patients with severe SIH defined as Glasgow Coma Scale (GCS) lower than 9. We determined serum CCCK-18 levels at the severe SIH diagnosis moment. RESULTS We found that non-surviving SIH patients (n = 46) showed lower GCS, and higher serum CCCK-18 levels and APACHE-II score than survivor ones (n = 54). In ROC analysis was found that the area under the curve of serum CCCK-18 levels for 30-day mortality prediction was 90% (95% CI 82-95%; p < 0.001). In the multiple logistic regression analysis, we found an association between serum CCCK-18 levels and 30-day mortality (OR 1.034; 95% CI 1.013-1.055; p = 0.002). CONCLUSIONS The novel finding of our study was that there is an association between high serum CCCK-18 levels and 30-day mortality in severe SIH patients.
