ABSTRACT

Objective:To study the past 10 years' experiences of neonatal hydrocephalus in a single-center.Methods:From January 2010 to December 2019, clinical data of infants with hydrocephalus admitted to Neonatology Department of our hospital were retrospectively analyzed. The infants were assigned into different groups according to gestational age, different etiologies and treatments. Their clinical characteristics and outcomes were compared.Results:A total of 223 infants with hydrocephalus were included. 136 (61.0%) infants were in the preterm group and 87 (39.0%) in the full-term group. The incidence of post-intracranial hemorrhage (ICH) hydrocephalus in preterm infants was significantly higher than full-term infants ( P<0.001). According to the etiologies, 58 infants (26.0%) had congenital hydrocephalus (congenital group), 82 cases (36.8%) developed post-ICH hydrocephalus (ICH group), 48 cases (21.5%) had post-CNS-infection hydrocephalus (infection group) and 35 cases (15.7%) had post-ICH+CNS-infection hydrocephalus (ICH+infection group). The incidences of perinatal asphyxia, neonatal resuscitation and endotracheal intubation within 3 d after birth in the ICH group were significantly higher than the other groups ( P<0.05). Among the four groups, the infection group had the highest incidence of neonatal sepsis, the congenital group had the highest incidence of patent ductus arteriosus and the ICH group had the highest incidence of respiratory diseases (all P<0.05).137 cases (61.4%) received non-surgical therapy, 48 cases (21.5%) had temporary drainage, 37 cases (16.6%) with permanent shunt and 1 case (0.4%) intracranial hematoma removal. The congenital group and ICH group with permanent shunt showed significantly higher rate of improvement than temporary drainage group and non-surgical group ( P<0.001). Conclusions:The main etiologies of neonatal hydrocephalus are ICH and CNS infection. The incidence of post-ICH hydrocephalus in premature infants was quite high. Hydrocephalus of different etiologies have different comorbidities. Maternal and infant care during pregnancy and delivery, prevention of neonatal sepsis and ICH are crucial in the prevention of hydrocephalus. More studies are needed for better treatment.

ABSTRACT

Objective:To analyze the changes of peripheral perfusion index (PPI) with late-onset sepsis (LOS) in very low birth weight infants during hospitalization.Methods:Very low birth weight infants admitted to the neonatal intensive care unit of Children′s Hospital of Fudan University from August 1, 2021 to August 31, 2022 were consecutively included.Infants with admission age ≥three days and unstable circulation, or positive blood culture within three days after birth were excluded.From the day of admission, the PPI values of the right hand and either foot of the infants were measured with Masimo SET Radical-7 everyday while whether LOS occurred during hospitalization was observed.The mean PPI curve of very and extremely low birth weight infants without LOS was plotted.For those with LOS confirmed by blood culture, the PPI change trajectory three days before and after the occurrence of LOS was drawn, and the change trend of PPI before the occurrence of LOS was analyzed by trend chi-square test.Non-parametric test was used to analyze the effect of LOS on pre- and post-ductal PPI values.Results:A total of 107 very low birth weight infants were included in the final analysis.Among them, there were 11 infants confirmed as LOS by blood culture, 37 infants diagnosed as clinical LOS, and 59 infants without LOS.Pre-and post-ductal PPI values of very low birth weight infants without LOS were 2.06±1.30 and 1.72±0.92, respectively; those with clinical LOS were 1.90±0.94 and 1.58±0.83, respectively; those with LOS confirmed by blood culture were 1.92±1.11 and 1.62±0.82, respectively.For infants with LOS confirmed by blood culture, the pre-and post-ductal PPI values showed a continuous downward trend during three days before the onset of disease, with the lowest PPI values on the first day before the diagnosis of blood culture.The downtrend of pre-ductal PPI was statistically significant ( χtrend2=5.57, P<0.05). Conclusion:The PPI value of very low birth weight infants show a downward trend when LOS occurs.It should be observed dynamically in clinical practice, which is helpful to suspect or identify LOS as early as possible.

ABSTRACT

Pellionia scabra belongs to the genus Pellionia in the family of Urticaceae, and is a high-quality wild vegetables with high nutritional value. In this study, high-throughput techniques were used to sequence, assemble and annotate the chloroplast genome. We also analyzed its structure, and construct the phylogenetic trees from the P. scabra to further study the chloroplast genome characteristics. The results showed that the chloroplast genome size was 153 220 bp, and the GC content was 36.4%, which belonged to the typical tetrad structure in P. scabra. The chloroplast genome encodes 130 genes, including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes in P. scabra. Among them, 15 genes contained 1 intron, 2 genes contained 2 introns, and rps12 had trans-splicing, respectively. In P. scabra, chloroplast genomes could be divided into four categories, including 43 photosynthesis, 64 self-replication, other 7 coding proteins, and 4 unknown functions. A total of 51 073 codons were detected in the chloroplast genome, among which the codon encoding leucine (Leu) accounted for the largest proportion, and the codon preferred to use A and U bases. There were 72 simple sequence repeats (SSRs) in the chloroplast genome of P. scabra, containing 58 single nucleotides, 12 dinucleotides, 1 trinucleotide, and 1 tetranucleotide. The ycf1 gene expansion was present at the IRb/SSC boundary. The phylogenetic trees showed that P. scabra (OL800583) was most closely related to Elatostema stewardii (MZ292972), Elatostema dissectum (MK227819) and Elatostema laevissimum var. laevissimum (MN189961). Taken together, our results provide worthwhile information for understanding the identification, genetic evolution, and genomics research of P. scabra species.

ABSTRACT

Congenital heart disease (CHD) is the most common congenital malformations, and critical CHD is one of the main causes of neonatal death and poor prognosis.Early screening and detection of congenital heart disease in newborns is helpful to early intervention and improve prognosis.At present, pulse oximetry alone, pulse oximetry combined with physical examination or pulse oximetry combined with cardiac murmur auscultation in early postnatal screening can detect most of critical CHD, but there are still some false negative results.Peripheral perfusion index (PPI) may have a certain value in finding left ventricular obstructive CHD that can not be found in the current screening methods.Therefore, this review summarized the technical principle and influence factors of PPI, its feasibility and effectiveness in neonatal CHD screening, and the possible threshold of screening, in order to provide a certain basis for PPI screening of neonatal CHD in the future.

ABSTRACT

Objective:To explore the types of venous access, indwelling time and the correlation with catheter-related bloodstream infection (CRBSI) of very and extremely low birth weight infants (VLBW & ELBW) in NICU.Methods:The self-designed venous access data collection form was used to collect the venous access data of VLBW & ELBW infants who were admitted to NICU of Children′s Hospital of Fudan University from January to December 2019. SPSS 22.0 software was used for data analysis, description and binary Logistic regression analysis.Results:A total of 218 cases were collected, including 9 cases of peripheral intravenous (PIV), 30 cases of PIV+ umbilical vein catheter (UVC), 43 cases of PIV+PICC, 136 cases of PIV+UVC+PICC. The average indwelling time of UVC was 6 days, the average indwelling time of PICC was 22 days. There were 23 cases (10.55%) got CRBSI and 195 cases (89.45%) without CRBSI. Binary Logistic regression analysis showed that birth weight ( OR=1.003, 95% CI 1.000-1.006, P<0.05) and combination form of venous access ( OR=0.139, 95% CI 0.023-0.834, P<0.05) of VLBW & ELBW infants were associated with CRBSI. Conclusions:In NICU, PIV, UVC and PICC are the three main ways to indwell venous access for VLBW & ELBW infants. The occurrence of CRBSI is closely related to the type and combination of indwelling venous access.

ABSTRACT

Objective:To investigate the safety, efficacy and application indication of intra-operative cell salvage (IOCS) in cesarean section.Methods:A total of 1 265 pregnant women who received IOCS blood transfusion during cesarean section in 11 tertiary A hospitals from August 2016 to January 2019 were collected and divided into <1 500 ml group (796 cases) and ≥1 500 ml group (469 cases) according to the amount of blood loss during cesarean section. The general clinical data, ultrasonic imaging data, perinatal and puerperium indicators were analyzed retrospectively. The risk factors of intraoperative blood loss ≥1 500 mL using IOCS transfusion were analyzed by logistic multivariate regression.Results:(1) A total of 848 001 ml of blood was recovered and a total of 418 649 ml of blood was transfused in 1 265 pregnant women who received IOCS transfusions, which was equivalent to 23 258 U red blood cell suspension, greatly saving medical resources. The intraoperative blood loss in <1 500 ml group and ≥1 500 ml group was 800 ml (300-1 453 ml) and 2 335 ml (1 500-20 000 ml), respectively. No amniotic fluid embolism, severe adverse reactions, shock and death occurred in the two groups. (3) Multivariate regression analysis showed that age ≥35 years ( OR=1.5, 95% CI: 1.1-1.9), prenatal hemoglobin level <110 g/L ( OR=1.7, 95% CI: 1.3-2.2), history of uterine surgery ( OR=1.8, 95% CI: 1.3-2.6), placenta previa ( OR=1.9, 95% CI: 1.1-3.1), placenta accreta ( OR=2.6, 95% CI: 1.8-3.9), blood pool in the placenta ( OR=1.6, 95% CI: 1.1-2.3), abnormal posterior placenta muscle wall ( OR=1.8, 95% CI: 1.2-2.6), placenta projecting to the anterior uterine wall ( OR=3.0, 95% CI: 1.3-7.0) were risk factors for blood loss ≥1 500 ml in obstetric transfusion using IOCS technique, with statistical significance (all P<0.05). Conclusion:IOCS is safe and effective in cesarean section, which could save the medical resources and reduces medical expenses, however, it is necessary to strictly master the application indication.

ABSTRACT

Objective@#To observe the changes in cerebral regional oxygen saturation (CrSO2) during neonatal blood exchange transfusion(BET) and its effect on the level of bilirubin in neonates with severe hyperbilirubinemia.@*Methods@#From January 2017 to March 2018, 52 newborns with severe hyperbilirubinemia were hospitalized in the Department of Neonatology, Children′s Hospital of Fudan University.Every newborn was treated with BET.Near infrared spectroscopy was used to monitor CrSO2 in the process of BET.The monitoring lasted from 2 hours before the beginning of BET to 2 hours after the completion of BET.The CrSO2 were recorded every 2 minutes and total surem bilirubin (TSB) and transcutaneous bilirubin(TCB) was measured.During this period, it is accompanied by the monitoring of neonatal body temperature, heart rate, respiration and bolld oxygen saturation(SpO2). The differences in CrSO2 changes at different time points during BET were compared.At the same time, the correlations between CrSO2 and blood oxygen saturation, TSB and TCB levels were analyzed.The results of repeated measurement analysis of variance compared between the two groups were corrected by Bonfferoni.@*Results@#Among the 52 children, there were 33 males (63.46%) and 19 females (36.54%). The gestational age, average birth weight and average head circumference of newborns were (38.6±2.1) weeks, (3 338±444) g and (33.6±3.2) cm, respectively.The Apgar score of newborn was (8.1±1.6) scores at 1 minute after birth.The level of TSB detected for the first time after admission was (457.9±97.8) μmol/L.The CrSO2 after BET (74.6%-76.0%) was significantly higher than that before BET (69.4%-69.0%), and the difference was statistically significant (P<0.05). Correlation analysis showed that during BET, CrSO2 showed a gradual upward trend, SpO2 also showed a synchronous increase, while the level of bilirubin showed a downward trend, and the downward trend of TSB level was more obvious than that of TCB.@*Conclusions@#CrSO2 can reflect the improvement of cerebral oxygenation during neonatal blood exchange transfusion and avoid cerebral hypoxia in the course of treatment.

ABSTRACT

Objective To investigate oral feeding progression and its influencing factors in very-low-birth-weight infants. Methods Investigation was conducted among 114 infants with the Gestational age≤30 weeks,birth weight≤1 500 g using very low birth weight infants clinical information questionnaire and oral feeding survey. Results The very low birth weight infants started enteral nutrition(20.61±4.67) h after admission, achieved a total enteral nutrition (41.47 ± 15.53) days after birth with the correct gestational age was (34.35 ± 2.76) weeks. The infants started oral feeding (41.47 ± 15.53) days after birth with the correct gestational age(34.58±1.98)weeks.The infants achieved full oral feeding(55.19±16.30) days after birth with the correct gestational age(36.40 ±1.99)weeks.Single factor and multiple regression analysis showed that birth weight,gestational age,BPD were significant factors of oral feeding progression. Conclusions The smaller gestational age, birth weight, the longer duration the infants reach the oral feeding milestones, Infants with BPD have obvious oral feeding progression. The medical staffs should learn that the very low birth weight have oral feeding difficulties and thus take positive and effective measures to promote the advancement of oral feeding.

ABSTRACT

Objective To investigate the incidence of the peripherally inserted central catheter (PICC) complications in neonates. Methods A retrospective analysis of PICC in 201 cases in our neonatal intensive care unit (NICU) from January 2015 to October 2016, who were divided into the central group and non-central group according to the position of the catheter tip. Compare unplanned extubation rate, catheter-related bloodstream infection rate, catheter indwelling time of PICC catheter and removing reasons between these two groups. Results One hundred and sixty-five cases in central group and thirty-six cases in non-central group. The unplanned extubation rate of the central group was 18.2% (30/165) while 22.2% (8/36) of non-central group, the difference wasnot statistically significant (χ2=0.315, P=0.639). The difference of the catheter-related bloodstream infection rate (P=0.471), the catheter indwelling time and removing reasons between these two groups were not statistically significant(P>0.05). Conclusions Even if the position of PICC tip is not in superior or inferior vena, it still can be used in neonatal population, but should pay attention to safe medical care.

ABSTRACT

Objective To investigate the incidence and clinical presentation of breast milk transmitted cytomegalovirus (CMV) infection among preterm infants with birth weight≤1500 g.Methods Preterm infants enrolled in this study met the following inclusion criteria: birth weight≤1500 g, fed with CMV-positive breast milk and admitted into Neonatal Intensive Care Unit of Children's Hospital of Fudan University within 72 hours after birth from October 2015 to July 2016. And those with congenital digestive tract malformation or congenital CMV infection were excluded. Breast milk and infants' urine samples were regularly screened for CMV DNA by fluorescent quantitative polymerase chain reaction. Symptoms and laboratory findings in infants with CMV infection transmitted via breast milk were documented and analyzed. Differences in relevant parameters were analyzed usingChi-square test, Fisher's exact test,t test or Mann-WhitneyU test where appropriately.Results Sixty preterm infants breastfed with CMV DAN-positive milk were recruited. Among them, 19 (31.7%) developed breast milk-acquired CMV infection as their urine samples were positive for CMV DNA, while the others were negative for CMV DNA (infected group:n=19; non-infected group:n=41). The average CMV copies in breast milk, gestational age and birth weight of the infected group were all significantly higher than those of the non-infected group [3.76 (3.18-4.50) vs 3.47 (3.00-4.88) Log10 copies/ml,Z=-2.042;(30.4±2.1) vs (28.4±2.3) weeks,t=3.175; 1290 (750-1500) vs 1110 (575-1480) g,Z=-2.837; all P0.05]. Four infants (21.1%, 4/19) had severe organ damage and/or positive IgM antibodies to CMV in serum, and were treated with antiviral therapy. Two had mild symptoms and were not given antiviral therapy. All of the six symptomatic infants were followed-up for one to six months, during which time the complete blood cell count and results of biochemical test and fundus examination were back to normal.Conclusions The incidence of breast milk-acquired CMV infection among preterm infants with birth weight≤ 1500 g was 31.7%, and no severe symptoms were reported in this study.

ABSTRACT

Objective To evaluate whether changes in neonatal intensive care have improved outcomes for extremely low birth weight (ELBW) infants in neonatal intensive care unit (NICU). Methods A prospective phase-lag cohort study was performed in a tertiary level NICU. A meticulous nursing strategy based on neonatal individual developmental care assessment program theory and feasible ELBW minimization stimulus was developed. Conventional care was applied in 2013 (period Ⅰ) and gently caring was applied in 2014 (period Ⅱ). The outcomes of ELBW between these 2 periods were compared. Results During these two periods, thirty-seven infants were included in period Ⅰ and 41 infants in period Ⅱ. In periodⅠ46.0%(17/37) of the infants needed oxygen for at least 28 days, but in period Ⅱ it decreased to 24.4%(10/41), there was significant difference (χ2=3.990, P=0.046). The rate of breastfeeding increased from 27.0%(10/37) in periodⅠto 61.0%(25/41) in period Ⅱ, there was significant difference (χ2=9.061, P=0.003). There was no significant difference in the mortality rate and chronic lung disease (P>0.05). The incidence of intracranial hemorrhage decreased from 21.6%(8/37) to 4.9%(2/41), there was significant difference(P=0.041). Conclusions Gently caring may have resulted in less intracranial hemorrhage and improve breastfeeding rate. Parents are satisfied with gentle care and in light of these findings, gentle care deserves further exploration.

ABSTRACT

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma in the Western world,and is potentially curable with standard R-CHOP chemoimmunotherapy. We are now in an era that the heterogeneity of DLBCL is defined genetically and molecularly,and rational subset-specific therapeutic targets are guiding clinical trials.Primary mediastinal DLBCL is a unique clinicopathologic entity, and alternatives to R-CHOP may confer superior outcome. Rearrangement of the myc oncogene occurs in 10%of patients with DLBCL, and confers a very poor prognosis with standard R-CHOP, particularly when there is concomitant rearrangement of bcl-2, a condition referred to as double-hit DLBCL. A larger subset of DLBCL demonstrates overexpression of both myc and bcl-2 by immunohistochemistry. Analyze the source of cells by gene expression profile, immunohistochemistry algorithms,or a novel Lymph2Cx platform,provides prognostic information, and guides therapeutic decisions in both relapsed and de novo disease. This article reviews latest research presented at the 57th American Society of Hematology (ASH) annual meeting on the definition of specific subsets of DLBCL and selection of subtype-specific treatment,including novel approaches under investigation. Understanding these key features of the pathology report, and limitations of these assays defining subsets of DLBCL, allows for a precision medicine approach to this disease.

ABSTRACT

Outcomes for patients with hemophilia have improved dramatically over the past 50 years.With the increased availability of safe clotting factor concentrates,the primary focus in clinical management is now the prevention of long-term complications,most notably the debilitating hemophilic arthropathy that is associated with severe disease.Definitive evidence of improved clinical results from primary prophylaxis started in young patients-with severe hemophilia A and a minimal bleeding history is presented.Furthermore,recent studies showing benefits for initiating prophylaxis in older adolescents and adults with established joint disease are examined.lnhibitors to factor Ⅷ are the most problematic complication of factor replacement therapy.Patient-specific and treatment-related factors that contribute to the risk of inhibitor formation are discussed and controversies and clinical evidence related to approaches for tolerance induction are reviewed.Immune tolerance induction is the proven method for eradication of inhibitors.This article reviews latest research presented at the 55th ASH annual meeting on the hemophilias and their clinical management.
