RESUMEN
Objective To assess the value of acute gastrointestinal injury(AGI)and intestinal fatty acid-binding protein(I-FABP)in the prognosis of liver cirrhotic patients with sepsis.Methods Clinical data of 84 liver cirrhosis patients with sepsis who were admitted to the intensive care unit(ICU)of a hospital from September 2020 to March 2023 were analyzed retrospectively,and 41 patients with decompensated liver cirrhosis during the same period were selected as the control group.Serum I-FABP level in patients was determined with enzyme-linked immunosorbent assay(ELISA).Scores of the model of end-stage liver disease(MELD)and sequential organ failure assessment(SOFA)were calculated.AGI was evaluated based on medical records.30-day and 90-day survival was observed.Correlation among variables was analyzed by Spearman correlation.Risk factors for death in patients with liver cir-rhosis and sepsis was determined by multivariate Cox regression analysis.The optimal cut-off value was determined by receiver operating characteristic(ROC)curve,and the diagnostic efficacy was compared through the area under the ROC curve(AUC).Results Both AGI grading and I-FABP level in liver cirrhosis patients with sepsis were higher than those in the control group(both P<0.05).I-FABP level was correlated with procalcitonin(PCT),MELD,and SOFA scores in patients with liver cirrhosis and sepsis(all P<0.05).AGI grading was positively cor-related with SOFA score(P=0.038).The 30-day and 90-day mortality of patients in the liver cirrhosis with sepsis group were 25.0%(n=21)and 35.7%(n=30),respectively.Multivariate Cox regression analysis showed that baseline I-FABP and SOFA scores were independently correlated with 30-day and 90-day survival,and the I-FABP quartile showed good prognostic differentiation efficacy.ROC curve showed that I-FABP could significantly improve the predictive effect of SOFA score on the prognosis of patients.Conclusion AGI grading and I-FABP level in liver cirrhosis patients with sepsis are elevated significantly.Serum I-FABP is associated with the prognosis of patient and can improve the predictive efficacy of SOFA score for survival.
RESUMEN
OBJECTIVE@#To study whether there are differences in the resuscitation process and early outcomes between the extremely preterm infants delivered on off-hours (6 pm to 8 am of working days, weekends, and national holidays) and those delivered on working hours.@*METHODS@#A retrospective analysis was performed on the medical data of extremely preterm infants who were born in the Peking University Third Hospital from January 1, 2010 to December 31, 2020 and transferred to the neonatal intensive care unit (NICU). According to the time of birth, they were divided into two groups:working hours (@*RESULTS@#Compared with the working hours group, the off-hours group had a significantly lower proportion of infants with the use of full-dose dexamethasone before delivery (@*CONCLUSIONS@#Extremely preterm infants delivered on off-hours tend to have a low Apgar score at 1 minute after birth, with a higher proportion of infants requiring positive pressure ventilation or tracheal intubation during resuscitation than those delivered on working hours, and they tend to develop neonatal respiratory distress syndrome and intrauterine pneumonia. This suggests that it is important to make adequate preparations in terms of personnel and supplies for resuscitation of extremely preterm infants after birth and that NICUs should develop a detailed management plan for extremely preterm infants at each period of time before, during, and after birth.

A female infant was admitted to the hospital due to perioral cyanosis two hours after birth. The infant was born at the gestational age of 35 weeks by cesarean section with a birth weight of 2 400 g. Physical examination revealed wry mouth to the left side while crying, small auricles, and high palatal arch; fibrolaryngoscopy suggested bilateral vocal cord paralysis; echocardiography suggested ventricular septal defect; single nucleotide polymorphism testing showed 22q11.21 microdeletion. Therefore, the infant was given a definite diagnosis of asymmetric crying facies syndrome accompanied by 22q11.21 microdeletion. After 8-month follow-up, the infant still had asymmetric crying facies with presence of growth retardation.

OBJECTIVE@#To investigate the physical development, incidence of common respiratory diseases, and motor development during infancy in preterm infants with bronchopulmonary dysplasia (BPD).@*METHODS@#A retrospective analysis was performed on the clinical features and infantile outcomes of preterm infants with BPD who were admitted to the neonatal intensive care unit between January 2012 and December 2015. Preterm infants without BPD were used as controls who were admitted to the neonatal intensive care unit during the same period and had similar gestational age and birth weight. Physical development, number of hospital stays, the incidences of pneumonia and wheezing, and motor development during infancy were compared between the two groups.@*RESULTS@#Compared with the control group, BPD infants had a significantly higher incidence of extrauterine growth retardation at discharge (48% vs 41%; P<0.05); BPD infants were more susceptible to pneumonia, wheezing, eczema and rhinitis; BDP infants also had a significantly higher number of readmissions due to respiratory tract infection (P<0.05). BPD infants had a significantly smaller head circumference than the control group at corrected ages of 3, 6, and 12 months (P<0.05). BPD infants had significantly delayed gross, fine, and overall motor development than the control group at corrected ages of 6 and 9 months (P<0.05).@*CONCLUSIONS@#Infants with BPD are susceptible to extrauterine growth retardation at discharge. Their head circumference growth is relatively slow. They are susceptible to pneumonia and wheezing during infancy. Moreover, they have delayed motor development when compared with those without BPD at corrected ages of 6 and 9 months.

A boy aged 2 months (born at 36 weeks of gestation) was admitted due to cough and dyspnea. After admission, he was found to have persistent hypertension, proteinuria, and persistent convulsion, and imaging examination showed extensive calcification of the aorta and major branches and stenosis of local lumens of the abdominal aorta and the right renal artery with increased blood flow velocity. The boy was admitted during the neonatal period due to wet lung and pulmonary arterial hypertension and was found to have hypertension and proteinuria. High-throughput whole-exome sequencing was performed and found two compound heterozygous mutations in the ENPP1 gene from his parents, c.130C>T (p.Q44X) and c.1112A>T (p.Y371F). c.130C>T was a nonsense mutation, which could cause partial deletion of protein from 44 amino acids, and was defined as a primary pathogenic mutation. c.1112A>T was a missense mutation which had been reported as a pathogenic mutation associated with idiopathic infantile arterial calcification (IIAC). Therefore, he was diagnosed with IIAC. He was given phosphonate drugs, antihypertensive drugs, anticonvulsion treatment, and respiratory support. Blood pressure was maintained at the upper limit of normal value. There was no deterioration of arterial calcification. It is concluded that IIAC should be considered for infants with persistent hypertension and extensive vascular calcification, and imaging and genetic examinations should be performed as early as possible to make a confirmed diagnosis.

<p><b>OBJECTIVE</b>To study the relationship between the degree of white matter damage and changes in brain function in premature infants early after birth according to amplitude-integrated electroencephalogram (aEEG) and raw EEG (with burst-suppression patterns).</p><p><b>METHODS</b>Thirty-eight premature infants of less than 32 weeks' gestational age and with white matter damage, including 20 cases of mild white matter damage and 18 cases of severe white matter damage, were included in the study. Forty-two premature infants without white matter damage were selected as a control group. After birth, they were examined using aEEG and brain ultrasound once a week until four weeks after birth or a corrected gestational age of 32 weeks. The white matter damage and control groups were compared in terms of aEEG patterns and amplitudes and burst suppression ratio (BSR) on EEG.</p><p><b>RESULTS</b>The white matter damage and control groups had highly discontinuous patterns and had no complete sleep cycles. The lower amplitude was significantly smaller in the severe white matter damage subgroup than in the mild white matter damage subgroup and control group. There was alternating burst-suppression activity on the raw EEG in the white matter damage and control groups; and the severe white matter damage subgroup had a significantly longer suppression time and a significantly higher BSR on EEG compared with the mild white matter damage subgroup and control group.</p><p><b>CONCLUSIONS</b>Brain function monitoring should be performed in premature infants with white matter damage early after birth so as to detect cases of severe white matter damage in time.</p>

<p><b>OBJECTIVE</b>To investigate serum procalcitonin (PCT) concentrations in premature infants with different gestational ages at different times after birth.</p><p><b>METHODS</b>A total of 217 neonates without infection, including 102 premature infants and 115 full-term infants, were enrolled in this study. The premature infants were further divided by gestational age into three subgroups: 30-32 weeks (n=30), 33-34 weeks (n=35) and 35-36 weeks (n=37). All the infants were studied to evaluate serum PCT concentrations at 0-12, 13-24, 25-36, 37-48, 49-72, 73-96, 97-120 and 121-144 hours after birth.</p><p><b>RESULTS</b>In the newborns, serum PCT concentrations increased gradually after birth, reached peak values at about 24 hours after birth, and then gradually declined and dropped to normal values for children at about 96 hours after birth. In the premature infants, serum PCT concentrations reached peak values at about 36 hours after birth, later than in the full-term infants, then declined slowly and dropped to levels similar to the full-term infants at 96 hours after birth. Serum PCT concentrations in the 30-32 week subgroup remained at low levels after birth, and increased gradually, later than in other premature infants, at 37-48 hours after birth.</p><p><b>CONCLUSIONS</b>Early after birth, neonates have a changing serum PCT concentration, increasing first and then decreasing. Peak serum PCT levels appear later in premature infants than in full-term infants. Serum PCT concentrations of premature infants with a gestational age of under 32 weeks remain at relatively low levels within 36 hours after birth.</p>

<p><b>OBJECTIVE</b>To study the relationship between angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism and left ventricular mass (LVM) in newborns admitted to the neonatal intensive care unit (NICU).</p><p><b>METHODS</b>Seventy-two newborns admitted to the NICU were enrolled. ACE genotypes were determined by genomic DNA which was isolated from heel-prick blood. Disease status of the newborns was evaluated by the Neonatal Critical Score (draft) on postnatal day 1. LVM and LVM index (LVMI) were evaluated by echocardiography on postnatal days 1-3.</p><p><b>RESULTS</b>DD genotype was identified in 11 cases, ID genotype in 31 cases, and II genotype in 30 cases. There were no significant differences in clinical characteristics, critical score and body measurements in newborns with different genotypes. The DD genotype group showed significantly lower LVMI than the group with ID+II genotypes (29±4 g/m2 vs 35±8 g/m2; P<0.05).</p><p><b>CONCLUSIONS</b>ACE gene polymorphism is associated with the LVMI in newborns admitted to the NICU. The LVMI of DD genotype carriers is significantly lower than that of ID+II genotypes carriers, which suggests that D allele may be associated with the growth and development of left ventricular.</p>
