ObjectivesUsing systematic literature review to analyze the effects of levetiracetam (LEV) on neonatal safety during early pregnancy.MethodsThe scope of the literature must be English literature, published from 1997 to 2018. Meta-analysis was performed by random effects models.ResultsSeven literatures were included. A total of 672 cases exposed to LEV in treatment group and 772 234 cases in control groups were selected for meta-analysis. There was no significant difference in neonatal malignancy between treatment group and control group［OR=1.05, 95% CI (0.54, 2.02), P=0.37］. Further, we evaluated the effect of LEV monotherapy and polytherapy on neonatal safety, a total of 464 monotherapy cases and 632 polytherapy cases respectively were selected for meta-analysis. The results showed that there was no significant difference between these two therapies in neonatal malignancy ［OR=0.54, 95% CI(0.31, 0.96), P=0.32］.ConclusionsAs the papers we included, levetiracetam in the treatment of epilepsy during pregnancy is relatively safe for newborn.
ObjectiveTo sum up experiences of precaution and provide evidence to prevent such accidents in the future via analyzing the nosocomial infection in newborn babies who were infected by rotavirus.
MethodsWe investigated and monitored the 8 cases of nosocomial infection occurred between July 7th and July 14th, 2012 by epidemiologic and environmental hygienic methods, and analyzed the existing risk factors and took measures to control.
ResultsThere were 8 nosocomial infected cases among the 45 newborn babies who were hospitalized. The infection rate was 17.8% and the accident lasted for 7 days. The distribution of space, time and population was clustered. Environment and hands were the main media to spread the virus.
ConclusionThe accident was a suspected nosocomial infection caused by rotavirus in the hospital. It can be controlled effectively through intensive cleaning and sterilizing, isolated touching, and improving the medical staff's compliance and accuracy rate of hand sanitation.
In October 2020, the American Heart Association issued the 2020 edition of guidelines for cardiopulmonary resuscitation and cardiovascular first aid, which comprehensively revised cardiopulmonary resuscitation and emergency cardiovascular care guidelines related to adults, children, newborns, resuscitation education science and treatment system. According to the latest edition of International Liaison Committee on Resuscitation’s classes of recommendation and levels of evidence, relevant suggestions are put forward. This article interprets the main updated and revised content, including children’s basic and advanced life support and neonatal resuscitation, in order to better guide emergency personnel and improve the quality of cardiopulmonary resuscitation and cardiovascular first aid.
ObjectiveTo study the phenotype of children with KCNQ2 gene related epilepsy.MethodsForty epilepsy children who were detected with KCNQ2 gene variants were enrolled. Their genotype and phenotype were analyzed.ResultsThirty-six KCNQ2 variants were identified. Twenty variants were novel. Twelve patients had inherited variants, and 28 patients had de novo variants. The age of seizure onset was from one day to 9 months. 80.0% patients had their seizure onset in neonates (32/40). Multiple seizure types were observed. Focal seizure was observed in 38 patients (95.0%). Epileptic spasm was observed in 10 patients (25.0%). Myoclonic seizure was observed in 4 patients. Tonic spasm seizure was observed in 3 patients. In all patients, seizures manifested in clusters. In 28 patients with de novo KCNQ2 variants, 24 had development delay (85.7%), the other 4 patients had normal development. In 12 patients with inherited KCNQ2 variants, one had development delay, the other 11 patients had normal development (91.7%). The most common interictal EEG changes were local epilepsy discharges (31/40). The MRI of brain was abnormal in 14 patients with de novo KCNQ2 variants and developmental delay. The agenesis of corpus callosum was identified in 10 patient (25.0%). Enlargement of subarachnoid spaces in the frontal and temporal region was identified in 11 patients (27.5%). Cortial dysplasia in the bilateral frontal and temporal region was identified in 2 patients. Sulus deepening was identified in 4 patients. Enlargement of bilateral lateral ventricle was identified in 3 patients. In 40 patients with KCNQ2 variants, 3 were diagnosed as benign familial neonatal epilepsy (BFNE), 2 were diagnosed as benign familial neonatal-infantile epilepsy (BFNIE), 3 were benign familial infantile epilepsy (BFIE), 3 were benign infantile epilepsy (BIE), 5 were benign neonatal epilepsy (BNE), 3 wer Ohtahara syndrome (OS), 9 were West syndrome (WS), 12 were unclassified early infantile epileptic encephalopathy (EIEE), one was epilepsy with autism. Sodium channel blockers oxcarbazepine was the most effective among antiepileptic drugs, with a effective rate of 90.9%.ConclusionsMost KCNQ2 variants are missense variants. De novo variants are more common in patients with KCNQ2 variants. The clinical features of patients with KCNQ2 variants including that mainly with seizure onset in neonate, the main seizure type is focal seizures, seizures occur in clusters. Patients with de novo KCNQ2 variants often had developmental delay, and about half of them had frontal and temporal lobe dysplasia and agenesis of corpus callosum. Sodium channel blockers are effective agents for epilepsy patients with KCNQ2 variants.
Objective To assess the effectiveness of intravenous immunoglobulin G (IVIG) in reducing the need for exchange transfusion in neonates with proven haemolytic disease due to Rh and/or ABO incompatibility. To evaluate the effectiveness of IVIG in reducing the duration of phototherapy and hospital stay. Methods We electronically searched CENTRAL, MEDLINE (1966 to May 2008), EMBASE (1992 to May 2008), CBMdisc (November 1979 to May 2008), and also checked the reference lists of all papers identified. According to the Cochrane Handbook for Systematic Reviews of interventions, randomized controlled trials comparing IVIG and phototherapy with phototherapy alone in neonates with Rh and/or ABO incompatibility were identified and analyzed. Results Six RCTs were included. The meta-analysis showed that, IVIG can significantly decrease the requirements of exchange transfusion (RR=0.27, 95%CI 0.18 to 0.42), the duration of hospitalization (WMD= –1.11, 95%CI –1.60 to –0.63) and the duration of phototherapy (WMD= –0.82, 95%CI –1.16 to –0.47). Conclusions Intravenous immunoglobulin (IVIG) is recommended for treating hemolytic disease of the newborn because it is effective in decreasing the requirements of exchange transfusion, the duration of hospitalization and phototherapy. Well designed studies with large sample in multi-center are required for further proving.
In November 2019, the American Heart Association updated guidelines for cardiopulmonary resuscitation (CPR) and emergency cardiovascular care. This update is not a comprehensive revision of the 2015 version. The updates for children and newborns mainly include three aspects: ① Pediatric basic life support: A. It is recommended that emergency medical dispatch centers offer dispatcher-assisted CPR instructions for presumed pediatric cardiac arrest. B. It is recommended that emergency dispatchers provide CPR instructions for pediatric cardiac arrest when no bystander CPR is in progress. ② Pediatric advanced life support: A. The bag-mask ventilation is reasonable compared with advanced airway interventions (endotracheal intubation or supraglottic airway) in the management of children during out-of-hospital cardiac arrest (OHCA). B. The extracorporeal CPR may be considered for pediatric patients with cardiac diagnoses who have in-hospital cardiac arrest (IHCA) in settings with existing extracorporeal membrane oxygenation protocols, expertise, and equipment. C. Continuous measurement of core temperature during targeted temperature management is recommended; for infants or children between 24 hours and 18 years of age who remain comatose after OHCA or IHCA, targeted temperature management is recommened. ③ Neonatal resuscitation: A. In term and late-preterm newborns (≥35 weeks of gestation) receiving respiratory support at birth, the initial use of 21% oxygen is reasonable. B. One hundred percent oxygen should not be used to initiate resuscitation because it is associated with excess mortality. C. In preterm newborns (<35 weeks of gestation) receiving respiratory support at birth, it may be reasonable to begin with 21% to 30% oxygen.
Objective To investigate the method and conditions of isolation，proliferation of multipotent mesenchymal stem cells（MSCs）from human umbilical cord blood in vitro, and to induce osteogenic and adipogenic differentiation directly for identification. Methods Human umbilical cord blood was collected in asepsis condition, isolated by density gradient centrifugation,or sedimented red cell with methylcellulose, and then the same centrifugation was done, or obtained by negative immunodepletion of CD34+. These isolated mononuclear cells were used to carry on plastic adherent culture. To obtain single cellderived colonies, these cells were proliferated clonally in medium which consists of L-DMEM orMesencultTM medium and 10% fetal calf serum（FCS） respectively, then their differentiation potentiality to osteoblasts and lipoblasts was tested. Results The mononuclear cells isolated by sedimented and centrifugated way cultured in MesencultTM medium and 10%FCS were most available. These adhesive cells could become obviously short rodshape or shuttle-shape cells after 5-7 days.The colonies form well in 3rdpassage cells. The mononuclear cells obtained by onlycentrifugalized in density gradient were hard to form colony, isolated by immunomagnetic beads were hard to culture. The surface antigens of these colonies cells presented CD29, CD59, CD71 but not CD34,CD45 and HLADR etc. The colony cells differentiating into osteoblasts that produce mineralized matrices, stained by alizarin red, and differentiating into adipocytes that accumulate lipid vacuoles, stained by oil red. Conclusion MSCs can be isolated from human umbilical cord blood and proliferate it in vitro. The way that mononuclear cells are sedimented red cell by methylcellulose and cultured by MesencultTM medium and 10% FCS is the valid method of isolation. Proliferation colonies cells present matrix cell immunophenotypes, and candifferentiate into osteoblasts and adipocytes.
ObjectiveTo evaluate the quality of Chinese guidelines of newborns so as to provide references for the formulation of relevant guidelines for newborns in the future.MethodsCBM, VIP, WanFang Data, CNKI and Medlive databases were systematically searched to collect clinical practice guidelines in neonatal field in China from January 1st, 2000 to June 28th, 2020. Four researchers independently screened literature, extracted data, used AGREEⅡ to evaluate the methodological quality of the guidelines, used RIGHT to evaluate the reporting quality of the guidelines, and analyzed the score and reporting rate of items in each field.ResultsA total of 35 guidelines were included, and the quantity of publications increased annually. The AGREEⅡ score showed that guidelines published after 2017 were rated higher in all areas than that prior to 2017, with clarity scoring highest (82.9%) and editorial independence scoring lowest (15.4%). The RIGHT score showed that guidelines published after 2017 had higher reporting rates in most areas than that prior to 2017. The highest proportion of reported areas was basic information (75.6% vs. 65.0%). Areas with the lowest reporting ratios in the guidelines prior to 2017 were review and quality assurance (0%), while after 2017 were other areas (4.4%).ConclusionsNeonatal guidelines in China have developed rapidly and the quality of the guideline still requires improvement.
Objective
To systematically review the diseases constitution of children in Chinese medical institutions from 2010 to 2016, and to provide evidence for establishing essential medicine list for children (EMLc) of China.
Methods
We searched PubMed, EMbase, The Cochrane Library, CBM, CNKI, VIP and WanFang Data from January 2010 to February 2016 to collect studies about diseases constitution of Chinese children. Two reviewers independently screened literature, extracted data, and assessed the risk bias of included studies, then data was descriptively analyzed.
Results
A total of 33 studies of diseases constitution were included, involving 1 797 696 children among 0 to 18 years from 17 provinces of China. Neonatal hyperbilirubinemia, neonatal pneumonia and premature were the main diseases of inpatient newborns. The main diseases of children hospitalized were pneumonia, upper respiratory tract infection and tumor. Upper respiratory tract infection, bronchopneumonia, bronchitis and diarrhea were the main diseases of outpatients. Hyperspasmia, upper respiratory tract infection and pneumonia were the main diseases of emergency patients. Diseases constitution of different medical institution: the main diseases were pathological jaundice, neonatal asphyxia and neonatal pneumonia in both tertiary and secondary medical institution in the newborn group. In the children group, the main diseases were pneumonia, upper respiratory tract infection and bronchitis in both tertiary and secondary medical institution. Besides these diseases, indigestion and fever of unknown origin were also the main diseases of primary medical institution. Disease constitution of different areas: in the newborn group, pathological jaundice, neonatal pneumonia and neonatal hyperbilirubinemia were the main diseases in coastal areas. Neonatal pneumonia, neonatal hyperbilirubinemia and premature were the main diseases in inland areas. Neonatal hyperbilirubinemia, neonatal pneumonia and neonatal hypoxic-ischemic encephalopathy were the main diseases in remote areas. In children group, pneumonia, bronchitis and premature were the main diseases in coastal areas. Pneumonia, bronchitis and hand-foot-and-mouth disease were the main diseases in inland areas. Upper respiratory tract infection, bronchopneumonia and bronchitis were the main diseases in remote areas.
Conclusion
Diseases constitutions of children vary in different medical institution, and because of extreme lack of date from primary medical institution, we suggest to carry out investigation in primary medical institution to provide evidence for EMLc. Diseases constitutions of children vary in different area, additions should be made according to local conditions when essential drugs of children selected. Newborn, as a special group of children, should be considered separately when EMLc of China established.
