ABSTRACT

Objective:To analyze the distribution of ages at the interhospital transfer of outborn very preterm infants in China and to compare their perinatal characteristics and outcomes at discharge and neonatal intensive care unit (NICU) treatment.Methods:A total of 3 405 outborn very premature infants with a gestational age of 24-31 +6 weeks who were transferred to the NICUs of the Chinese Neonatal Network (CHNN) in 2019 were included in this retrospective study. According to the age at transfer, they were divided into three groups: early transfer (≤1 d), delayed transfer (>1-7 d) and late transfer (>7 d) groups. Analysis of variance, t-test, Chi-square test (Bonferroni correction), Kruskal-Wallis test and Wilcoxon rank-sum test were used to compare the general clinical condition, treatment, and outcomes at discharge among the three groups. Results:The median gestational age was 29.7 weeks (28.3-31.0 weeks) and the average birth weight was (1 321.0 ± 316.5) g for these 3 405 infants. There were 2 031 patients (59.6%) in the early transfer group, 406 (11.9%) in the delayed transfer group and 968 (28.4%) in the late transfer group. Infants who received continuous positive airway pressure ventilation and tracheal intubation in the delivery room accounted for 8.4% (237/2 806) and 32.9% (924/2 805), respectively. A total of 62.7% (1 569/2 504) of the mothers received antenatal glucocorticoid therapy and the ratio in the early transfer group was 68.7% (1 121/1 631), which was higher than that in the delayed transfer group [56.1% (152/271), χ2=16.78, P<0.017] and the late transfer group [49.2% (296/602), χ2=72.56, P<0.017]. The total mortality rate of very premature infants was 12.7% (431/3 405), and the mortality rates in the early, delayed and late transfer groups were 12.4% (252/2 031), 16.3% (66/406) and 11.7% (113/968), respectively ( χ2=5.72, P=0.057). The incidences of severe intraventricular hemorrhage, late-onset sepsis, necrotizing enterocolitis, and bronchopulmonary dysplasia at the corrected gestational age of 36 weeks or discharge were all higher in the delayed and late transfer groups than in the early transfer group, respectively. The incidences of retinopathy of prematurity, retinopathy of prematurity requiring treatment and bronchopulmonary dysplasia at the corrected gestational age of 36 weeks or discharge in the late transfer group were significantly higher than that in the delayed transfer group (Bonferroni correction, all P<0.017). In the late transfer group, the median age of very premature infants at discharge was 66.0 d (51.0-86.0 d), and the corrected gestational age at discharge was 38.9 weeks (37.1-41.2 weeks), and both were greater than those in the early transfer [48.0 d (37.0-64.0 d), Z=260.83; 36.9 weeks (35.7-38.3 weeks), Z=294.32] and delayed transfer groups [52.0 d (41.0-64.0 d), Z=81.49; 37.4 weeks (36.1-38.7 weeks), Z=75.97] (all P<0.017). Conclusions:Many very premature infants need to be transferred to higher-level hospitals after birth. The later the very premature infants are transferred, the higher the incidence of complications will be. It is suggested that intrauterine or early postnatal transport may improve the prognosis of very premature infants.

ABSTRACT

OBJECTIVE@#To explore the clinical features and genetic basis for a child with 3-methylglutaconic aciduria type VII.@*METHODS@#A child who was diagnosed at the Gansu Provincial Maternity and Child Health Care Hospital on August 9, 2019 was selected as the study subject. Clinical data of the child, including urine gas chromatography and mass spectrometry, were collected. The child and her parents were subjected to whole exome sequencing.@*RESULTS@#The child, a female neonate, had presented mainly with intermittent skin cyanosis, convulsions, hypomagnesemia, apnea, neutropenia after birth. Her urine 3-methylpentenedioic acid has increased to 17.53 μmol/L. DNA sequencing revealed that she has harbored compound heterozygous variants of the CLPB gene, namely c.1016delT (p.L339Rfs*5) and c.1087A>G (p.R363G), which were respectively inherited from her mother and father. Both variants were unreported previously. Based on the standards from the American College of Medical Genetics and Genomics (ACMG), the variants were respectively predicted to be pathogenic and likely pathogenic.@*CONCLUSION@#The child was diagnosed with 3-methylglutenedioic aciduria type VII. Discovery of the c.1016delT and c.1087A>G variants has enriched the mutational spectrum of the CLPB gene.

ABSTRACT

We report the diagnosis and treatment of two cases of fetal intestinal volvulus. Case 1 presented to Gansu Provincial Maternity and Child-care Hospital due to reduced fetal movements at 33 +4 weeks of gestation. Case 2 was referred to our hospital from a local hospital because of fetal bowel dilatation by ultrasound at 32 +5 weeks. Both cases were found to have fetal bowel dilatation with typical "whirlpool" or "coffee bean" signs on ultrasound after admission. After multidisciplinary consultation and discussion, an emergency cesarean section was performed, during which the two neonates underwent surgical operation and resection of necrotic bowel loops after confirming the diagnosis of volvulus and intestinal necrosis. Case 2 suffered from pulmonary artery thrombosis after the bowel surgery, and underwent pulmonary artery incision and embolectomy within 24 hours. Both newborns recovered well after the operation, whose growth parameters and nervous system development was normal for follow-up.

ABSTRACT

Due to the improvement of infant survival rates,Candidas have been proved to be the third most common pathogen of late-onset sepsis in NICU,and invasive fungal infection of high-risk infants is in-creasing attention. As the diagnosis is difficult,treatment is often delayed,high mortality and severe disability are also caused,it's becoming a research hot spot to assess whether antifungal prophylaxis is beneficial. Now a number of studies have been performed to discuss the prophylactic role of fluconazole and nystatin,but has not yet reached a consensus. This review described the influence of chemoprophylaxis on fungal infection, colonization and drug resistance.

ABSTRACT

Background and objective As computed tomography (CT) screening for lung cancer becomes more common in China, so too does detection of pulmonary ground-glass nodules (GGNs). Although anumber of national or international guidelines about pulmonary GGNs have been published,most of these guidelines are produced by respiratory, oncology or radiology physicians, who might not fully understand the progress of modern minimal invasive thoracic surgery, and these current guidelines may overlook or underestimate the value of thoracic surgery in the management of pulmonary GGNs. In addition, the management for pre-invasive adenocarcinoma is still controversial. Based onthe available literature and experience from Shanghai Pulmonary Hospital, we composed this consensus about diagnosis and treatment of pulmonary GGNs. For lesions which are considered as adenocarcinoma in situ, chest thin layer CT scan follow-up is recommended and resection can only be adopt in some specific cases and excision should not exceed single segment resection. For lesions which are considered as minimal invasive adenocarcinoma, limited pulmonary resection or lobectomy is recommended. For lesions which are considered as early stage invasive adenocarcinoma, pulmonary resection is recommend and optimal surgical methods depend on whether ground glass component exist, location, volume and number of the lesions and physical status of patients. Principle of management of multiple pulmonary nodules is that primary lesions should be handled with priority, with secondary lesions taking into account.

ABSTRACT

Congenital central hypoventilation syndrome,also known as “Ondine′s curse”,is charac-terized by hypoventilation during sleep and impaired ventilatory responses to hypercapnia and hypoxemia. This disorder is associated with a malfunction of the nerves that control involuntary body functions and abnor-mal development of early embryonic cells that form the spinal cord. This review summarized the latest pro-gression in the pathogenesis,clinical symptoms,diagnosis,treatment and prognosis.

ABSTRACT

Objective To determine the effectiveness of endovascular embolization through pulmonary artery access in patients with refractory massive hemoptysis in whom systemic artery (SA)embolization is ineffective or contraindicated. Methods A total of 102 patients were treated with SA embolization for hemoptysis. Of the 102 patients, 6 patients had severe persistent hemoptysis despite complete SA embolization and 1 patient had severe hemoptysis following complete bronchial artery embolization and other SA embolization was contraindicated. The underlying diseases were chronic cavitary pulmonary tuberculosis (n = 3), chronic cavitary pulmonary tuberculosis complicated with aspergilloma (n=1), tuberculous bronchiectasis (n=1), severe necrotizing pneumonia (n=1) and bronchiectasis complicated with pneumatocele (n=1). The findings of SA angiography, main pulmonary angiography and selective pulmonary angiography were analyzed. Endovascular embolization was performed in patients with the detectable pathology in PA and the clinical results were observed. Results The findings of SA angiography showed bronchopulmonary shunting in all cases, and pseudoaneurysm of PA in 2 cases and hypertrophy of peripheral PA in 2 cases. The main PA angiography demonstrated pseudoaneurysm of PA in 1 case and hypoperfusion of the diseased PA in other case. The selective PA angiography demonstrated pseudoaneurysm of PA in 4 cases (1 case with extravasation of constrast medium) and hypertrophy ofperipheral PA in 2 cases. Coil embolizations of the pathologic PA were successfully performed and bleeding ceased in all patients. During follow-up, 1 patient had episodic bloody sputum after embolization, and 2 died day 6 and 15 of severe infection and respiratory failure and the remaining patients were all stable.Conclusions In patients with refractory massive hemoptysis after systemic embolization, the possibility of PA pathology, especially pseudoaneurysm of PA should be considered. Selective pulmonary angiography is necessary to demonstrate the pathology in PA. Endovascular management of the pathologic PA appears to be a safe and effective treatment.

ABSTRACT

BACKGROUND: Preliminary study has proven that adult human bone marrow-derived mesenchymal stem cells (MSCs) suppress peripheral blood lymphocytes proliferation.But the mechanism was still to be investigated.OBJECTIVE: To study the negatively regulatory effect of adult human MSCs on allogeneic lymphocyte proliferation by cell-free condition.DESIGN,TIME AND SETTING: Cytological observation in vitro,which was performed in the Lanzhou General Hospital,Lanzhou Military Area Command of Chinese PLA between October 2005 and December 2007.MATERIALS: The bone marrow sample was provided by the allo-transplantation donor.The peripheral blood lymphocytes were provided by the healthy volunteer.METHODS: Adult human MSCs were separated with Percoll + adherence method.Allogeneic peripheral blood lymphocytes were obtained from healthy donors with Ficoll solution and the cell concentration was adjusted as 2×109/L for use.100μ L MSCs culture supernatant was taken out in 96-well plates.The groups were following: A superuatant + 3-day MSCs culture media (100 μ L/well); B superuatant + phytohemagglutini (PHA; 1 g/L,5 μ L); C medium + LG-DMEM culture media containing 10% fetal bovine serum (100 μ L); D medium + PHA (1 g/L,5 μ L).The cells were incubated at 37 ℃ with 5% CO2 in a fully humidified atmosphere for three days.MAIN OUTCOME MEASURES: Effect of MSCs supematant on proliferation and transformation of variant lymphocytes.RESULTS: Peripheral blood lymphocytes proliferation was suppressed as compared with the blank control group and PHA group after MSCs culture,and the inhibition ratio was 9.00% (P < 0.05).When lymphocytes were stimulated by PHA,the suppression effects were even stronger and the inhibition ratio was 20.91% (P < 0.01).CONCLUSION: Adult human MSCs supernatant can suppress peripheral blood lymphocytes proliferation and transformation; furthermore,PHA can enhance the inhibitory effect,suggesting the negative regulation is at least in part due to indirectly inhibiting lymphocytes via soluble cytokines.
