    Objective: To compare the efficacy and safety of flow-driver-generated synchronized nasal intermittent positive-pressure ventilation (SNIPPV) and biphasic positive airway pressure (BiPAP) after extubation in preterm infants. Hypothesis: SNIPPV delivered via a flow-driver device improves post-extubation outcomes compared with non-synchronized BiPAP. Study Design: This single-center, retrospective, observational cohort study was conducted in the neonatal intensive care unit of Nagoya University Hospital, Nagoya, Japan. Patient Selection: Preterm infants born at < 34 weeks of gestation who underwent endotracheal ventilation after birth and were subsequently supported with either BiPAP (from October 2017 to March 2020) or SNIPPV (from April 2020 to September 2022) after extubation. Infants with major anomalies or surgical ventilator dependence were excluded. Methodology: Data on demographic and clinical characteristics, respiratory outcomes, and complications were collected. The primary outcome was reintubation within 72 h. Secondary outcomes were bronchopulmonary dysplasia (BPD), respiratory support duration, and major complications. Results: Sixty-seven infants were included (BiPAP n = 37, SNIPPV n = 30). Reintubation within 72 h occurred in 6.7% and 29.7% of infants in the SNIPPV and BiPAP groups, respectively (p = 0.028). The incidence of respiratory distress-related failure was significantly lower in the SNIPPV group (3.3% vs. 24.3%, p = 0.019). There were no significant differences in BPD at 36 or 40 weeks, oxygen therapy duration, or complications such as necrotizing enterocolitis, retinopathy of prematurity, or severe neurological injury. Conclusion: Flow-driver-generated SNIPPV significantly reduces early extubation failure in preterm infants compared to BiPAP without increasing the rate of adverse outcomes. This is a practical and effective alternative to noninvasive respiratory support.

    Background: Effective treatments for cerebral palsy caused by Hypoxic-ischemic encephalopathy are urgently needed. Current therapies primarily include prevention or acute intervention, leaving a major gap in the options for reversing established neurologic damage. Because of their ease of collection and unique trophic factor profile, stem cells from human exfoliated deciduous teeth (SHED) are promising candidates for cell-based therapy targeting neurological disorders. In this study, we examined the therapeutic potential of SHED in a rat model of cerebral palsy, focusing on neurogenic and functional recovery. Methods: Hypoxic–ischemic encephalopathy was induced in neonatal rats using the Rice–Vannucci method. Rats with motor impairments received intravenous SHED injections, whereas the control group received a vehicle solution. Behavioral tests assessed motor coordination and cognitive performance. Proteomic analyses and immunohistochemistry were performed to examine the underlying mechanisms. The migration and biodistribution of SHED were tracked using quantum dot-labeled SHED with in vivo imaging. Neural stem cells were cocultured with SHED to evaluate neurogenesis, followed by RNA sequencing and the analysis of trophic factors in the conditioned media. Results: SHED treatment significantly ameliorated motor coordination, memory, and learning. Proteomic analysis revealed increased expression of proteins associated with neurogenesis in the SHED group. Histopathologic evaluations revealed enhanced neurogenesis in the hippocampal dentate gyrus and subventricular zone 2 weeks posttreatment, with increased NeuN-positive cells in the hippocampus and cortex at ten weeks. In vivo imaging revealed the migration of quantum dot-labeled SHED to the brain. Neural stem cells co-cultured with SHED in vitro exhibited higher proliferation rates. The SHED-conditioned medium contained increased levels of hepatocyte growth factor (HGF), and HGF-neutralizing antibodies suppressed the enhanced cell proliferation. RNA sequencing revealed significant alterations in genes associated with the PI3K–Akt signaling pathway. Conclusions: SHED treatment ameliorated motor, memory, and learning impairment in a rat model of cerebral palsy. These improvements were accompanied by enhanced neurogenesis, likely mediated by HGF secretion and activation of the PI3K–Akt signaling pathway. SHED is a promising candidate for postsymptom-onset treatment of cerebral palsy. Further studies to confirm these findings and examine the clinical utility of SHED are warranted.

    In humans, fetal cerebellar development peaks during the final stages of pregnancy. Preterm infants experience hyperoxia (excessive oxygen) outside the uterus. Hyperoxia exposure causes neurological deficits in preterm infants. However, detailed mechanisms underlying hyperoxia-induced neurological deficits remain unclear. Previous studies on neurological deficits have focused on cerebral lesions. However, recently, cerebellar lesions have been observed on brain magnetic resonance imaging in preterm infants. We herein aimed to investigate behavioral and cerebellar tissue–level changes in Sprague–Dawley rat neonates exposed to 83% hyperoxia from within 24 h of birth to 14 days of age. In rats, cerebellar development peaks in the first postnatal week. We elucidated the mechanism by which hyperoxia exposure causes neurological deficits in these rats. We found that prolonged hyperoxia exposure, starting within 24 h of birth, induces behavioral impairments (such as motor, cognitive and memory, and social interaction deficits) in rats. At the tissue level, delayed granule cell migration and abnormal Purkinje cell dendritic development combined with impaired myelination were observed in the acute and chronic hyperoxia exposure phases, respectively. Thus, hyperoxia exposure may cause abnormalities in cerebellar morphology and function, resulting in neurological deficits in preterm infants.

    Background: To evaluate the efficacy and safety of gastric lavage (GL) in neonates with coffee-ground hematemesis due to swallowing maternal blood by postnatal day 1. Methods: This multicenter, randomized controlled trial included term neonates presenting coffee-ground hematemesis by postnatal day 1. Patients were randomly assigned to GL or non-GL groups. The primary outcome was the rate of feeding intolerance (FI) within 24 h. Secondary outcomes included onset of FI, residual gastric volume, vomiting episodes, weight changes, and bilirubin levels. Adverse events were monitored. Results: Eighty neonates were analyzed (40 per group). FI occurred in 15.0 % of the GL group and 27.5 % of the non-GL group (p = 0.17). However, in the subgroup of neonates exclusively fed with formula, FI was significantly lower in the GL group than in the non-GL group (16.0 % vs. 47.4 %, p = 0.02). GL significantly reduced residual gastric volume but showed no significant differences in other secondary outcomes. No adverse events related to GL were observed. Post hoc analysis indicated that a larger sample size would be needed to detect statistical significance; and subgroup findings suggested potential benefit in selected populations. Conclusions: GL did not significantly reduce the incidence of FI in neonates with coffee-ground hematemesis and thus it cannot be considered superior based on current results. However, it was well tolerated, and the study may have been underpowered. Exploratory analyses suggested potential benefits, particularly among formula-fed neonates, warranting further investigation.

    Background: An association between total hydrocortisone (HC) dosage in infants with extremely low birth weight (ELBW) and subsequent neurodevelopmental outcomes up to school age remains unclear. Method: We conducted a retrospective longitudinal cohort study across eight centers in Japan, including ELBW infants born between 2015 and 2017. We investigated the association between total HC dosage administered up to 36 weeks postmenstrual age and neurodevelopmental outcomes to school age. Results: Linear mixed model analysis showed a significant association between higher HC dosage and lower developmental and intelligence quotient (DQ/IQ) scores. This trend persisted at 6 years of age, suggesting a sustained effect of HC on cognitive outcomes. For every 10 mg increase in HC dosage, IQ scores decreased by 2.82 points (95% CI: −3.89 to −1.06, p = 0.001). The interaction term between HC dosage and time was not statistically significant (0.10, 95% CI: −0.18 to 0.37, p = 0.481), suggesting the association of HC dosage on DQ/IQ did not vary substantially throughout the study period. Conclusions: We found a relationship between total neonatal HC dosage in ELBW infants and DQ/IQ scores over time that persisted at school age. Clinicians should be aware of this potential dose-dependent effect on neurodevelopmental outcomes. Impact: As neonatal dexamethasone administration is known to affect neurodevelopment outcomes, hydrocortisone (HC) is considered an alternative to dexamethasone as a glucocorticoid treatment. In infants with extremely low birth weight (ELBW), a relationship has been noted between total HC dosage and neurodevelopment in early childhood. We confirmed the association between total HC dosage in infants with ELBW and poor developmental and intelligence quotients to school age. Although HC is commonly used in the management of ELBW infants, clinicians should be aware of its potential dose-dependent effects on neurodevelopmental outcomes.

    Introduction: The effects of hydrocortisone (HDC) administration to extremely low birth weight (ELBW) infants on later development remain unclear. This study examined the association between HDC dosage during neonatal period and neurodevelopmental outcomes in ELBW infants. Methods: This study was a retrospective cohort study conducted in eight centers in Japan. The subjects of this study were ELBW infants born between April 2015 and March 2017. The association between postnatal total HDC dosage up to 36 weeks postmenstrual age and the developmental quotient (DQ) at 3 years of age was examined. Multiple linear regression evaluated the association, adjusting for weeks of gestation, birth weight, and the presence of bronchopulmonary dysplasia, late-onset circulatory collapse, intracranial hemorrhage, necrotizing enterocolitis, and sepsis. Results: This study included 218 ELBW infants, of whom 144 underwent a developmental test at 3 years of age. Simple linear regression analysis revealed a significant association between total HDC dosage and DQ at 3 years of age (coefficients: −2.65, 95% CI: −3.73, −1.57). Multiple linear regression analysis adjusted for the presence of bronchopulmonary dysplasia and late-onset circulatory collapse also revealed a significant association between total HDC dosage and DQ at 3 years of age (coefficients: −2.66, 95% CI: −3.89, −1.42). Conclusion: Higher total HDC dosage up to 36 weeks postmenstrual age in ELBW infants was associated with impaired neurodevelopmental outcomes. Although HDC is often needed in the treatment of ELBW infants, clinicians should be aware that an increased dose of HDC may be associated with impaired neurodevelopmental outcomes.

    Multilineage-differentiating stress-enduring (Muse) cells are endogenous reparative pluripotent stem cells present in the bone marrow, peripheral blood, and organ connective tissues. We assessed the homing and therapeutic effects of systemically administered nafimestrocel, a clinical-grade human Muse cell-based product, without immunosuppressants in a neonatal hypoxic–ischemic (HI) rat model. HI injury was induced on postnatal day 7 (P7) and was confirmed by T2-weighted magnetic resonance imaging on P10. HI rats received a single dose nafimestrocel (1 × 10<sup>6</sup> cells/body) or Hank’s balanced salt solution (vehicle group) intravenously at either three days (on P10; M3 group) or seven days (on P14; M7 group) after HI insult. Radioisotope experiment demonstrated the homing of chromium-51-labeled nafimestrocel to the both cerebral hemispheres. The cylinder test (M3 and M7 groups) and open-field test (M7 group) showed significant amelioration of paralysis and hyperactivity at five weeks of age compared with those in the vehicle group. Nafimestrocel did not cause adverse events such as death or pathological changes in the lung at ten weeks in the both groups. Nafimestrocel attenuated the production of tumor necrosis factor-α and inducible nitric oxide synthase from activated cultured microglia in vitro. These results demonstrate the potential therapeutic benefits and safety of nafimestrocel.

    Introduction: To investigate the mechanism underlying the increased risk of subsequent neurodevelopmental disorders in children born to mothers with preeclampsia, we evaluated the neurodevelopment of offspring of a preeclampsia rat model induced by the administration of N-nitro-L-arginine methyl ester (L-NAME) and identified unique protein signatures in the offspring cerebrospinal fluid. Methods: Pregnant rats received an intraperitoneal injection of L-NAME (250 mg/kg/day) during gestational days 15–20 to establish a preeclampsia model. Behavioral experiments (negative geotaxis, open-field, rotarod treadmill, and active avoidance tests), immunohistochemistry [anti-neuronal nuclei (NeuN) staining in the hippocampal dentate gyrus and cerebral cortex on postnatal day 70], and proteome analysis of the cerebrospinal fluid on postnatal day 5 were performed on male offspring. Results: Offspring of the preeclampsia dam exhibited increased growth restriction at birth (52.5%), but showed postnatal catch-up growth on postnatal day 14. Several behavioral abnormalities including motor development and vestibular function (negative geotaxis test: p < 0.01) in the neonatal period; motor coordination and learning skills (rotarod treadmill test: p = 0.01); and memory skills (active avoidance test: p < 0.01) in the juvenile period were observed. NeuN-positive cells in preeclampsia rats were significantly reduced in both the hippocampal dentate gyrus and cerebral cortex (p < 0.01, p < 0.01, respectively). Among the 1270 proteins in the cerebrospinal fluid identified using liquid chromatography-tandem mass spectrometry, 32 were differentially expressed. Principal component analysis showed that most cerebrospinal fluid samples achieved clear separation between preeclampsia and control rats. Pathway analysis revealed that differentially expressed proteins were associated with endoplasmic reticulum translocation, Rab proteins, and ribosomal proteins, which are involved in various nervous system disorders including autism spectrum disorders, schizophrenia, and Alzheimer's disease. Conclusion: The offspring of the L-NAME-induced preeclampsia model rats exhibited key features of neurodevelopmental abnormalities on behavioral and pathological examinations similar to humans. We found altered cerebrospinal fluid protein profiling in this preeclampsia rat, and the unique protein signatures related to endoplasmic reticulum translocation, Rab proteins, and ribosomal proteins may be associated with subsequent adverse neurodevelopment in the offspring.

    周産期・新生児医療の現場では、周産期脳障害に伴う脳性麻痺などの神経発達障害が問題視されている。根本的な治療法は未確立のため新規治療法の開発は喫緊の課題であるが、中でも幹細胞治療は1つの解決策と考えられている。そのため我々の研究グループでは、採取、培養が容易な脱落乳歯歯髄幹細胞(SHED)に着目し、これまでにSHEDの急性期投与が周産期脳障害モデルに対し有効であることを証明してきた。
    一方、脳性麻痺は主に遠隔期に発症することから、脳性麻痺の症状を確認してからでも十分効果をもたらす治療法開発も必要である。
    そこで本研究では、SHEDを用いて遠隔期の神経障害発症後に効果を示す新規細胞療法の開発を行う。
    昨年度、我々は脱落乳歯由来歯髄幹細胞(SHED)を投与した脳性麻痺モデルラットを用いて免疫組織学的評価および生化学的評価を行い、SHEDの神経新生促進作用を明らかにした。今年度は、SHEDのもつ慢性期神経症状改善効果のさらなるメカニズム解明を目的として、追加解析を行った。
    網羅的遺伝子発現解析により、神経新生に関与する複数のシグナル伝達経路において、有意な変化が確認された。さらに、SHEDを量子ドットで標識し生体内でのイメージング解析を行った結果、投与後に標識細胞が脳内に移行・分布していることが明らかとなった。
    次に、SHEDや他の幹細胞(骨髄由来幹細胞、皮膚線維芽細胞など)と神経幹細胞(NSC)を48時間の共培養を行った。NSCは成獣ラット海馬歯状回からの初代培養細胞を使用した。共培養後のNSCからRNAを抽出し、RNA-seq解析を行った。その結果、他の幹細胞と比較してSHEDでは、Gene ontology 解析では細胞の発生過程に関係する遺伝子の有意な発現を認め、KEGG pathway 解析では細胞内シグナル伝達経路(PI3K-Akt signaling pathway)に関係する遺伝子の活性化を認めた。SHED投与により、NSCの分化・増殖に関与する機能が顕著に高まることが確認された。
    これらの結果から、SHEDは静脈内投与後に脳内へ移行し、内在性神経幹細胞の分化・増殖を促進することで、脳性麻痺モデルラットの神経症状を改善する可能性が示唆された。
    今年度は、量子ドットを用いたイメージング解析により、SHEDの脳内への移行・分布を解明することができた。さらに、SHEDの神経新生促進作用として、細胞発生過程や細胞内シグナル伝達経路の活性化といった新たなメカニズムの特定を行うことができた。そのため、今年度の進捗はおおむね達成することができたと考えられる。
    今後、SHEDの神経新生促進作用に関与する液性因子の同定を行うことで、慢性期神経症状改善効果のさらなるメカニズム解明を目指す。
    具体的には、SHEDとNSCの共培養上清を用いて定量抗体アレイによる液性因子の網羅的解析を行い、NSCの増殖と分化に関与する液性因子の同定を行う。さらに、同定した液性因子に対する中和抗体を用い、NSC増殖率の変化を確認していく予定である。

    Multilineage-differentiating Stress Enduring(Muse)細胞は、多能性を有し直接的に分化転換・組織修復を行うことができる間葉系幹細胞の数%を構成する細胞である。我々はHIEモデル動物で、Muse細胞が脳へ生着すること、並びに行動学的に学習及び運動障害の改善効果があることを確認した。現在HIEの治療法は、効果が限定的な低体温療法しかなく、新規治療法の開発が喫緊の課題とされている。本研究でMuse細胞を用いたHIEの新規治療法の開発を行うことにより、神経学的予後を改善する効果が期待できる。
