ABSTRACT

Abstract Objectives: to determine the prevalence and factors associated with recurrent wheezing in the first year of life among premature newborns from Neonatal Intensive Care Units, in the city of Montes Claros, northern Minas Gerais. Methods: cross-sectional study, with data collection from medical records of a follow-up clinic, interviews with mothers and, eventually, search in hospital records. Bivariate analyzes were carried out between sociodemographic and clinical characteristics and recurrent wheezing. Variables associated up to the level of 20% were analyzed by binary logistic regression, and associations defined by the Odds Ratio and respective 95% confidence intervals. Only variables associated with a 5% significance level were maintained in the final model of logistic regression. Results: among 277 infants studied, about one fifth (21.3%) were extremely low birth weight preterm and more than half (60.7%) had birth weight below 1500 grams. The prevalence of recurrent wheezing was 14.4% (CI95% = 10.3-18.4). Mechanical ventilation (OR = 2.12; CI95% = 1.09-4.76; p = 0.030) and oxygen therapy time ≥ 15 days (OR = 2.49; CI95%= 1.12-5.00; p = 0.010) were the risk factors for the event. Conclusions: there is a high prevalence of recurrent wheezing in the evaluated group and the associated variables reiterate the risk of prolonged oxygen therapy and mechanical ventilation for premature newborns.


Resumo Objetivos: determinar a prevalência e fatores associados à sibilância recorrente no primeiro ano de vida entre recém-nascidos prematuros egressos de Unidades de Terapia Intensiva Neonatais, na cidade de Montes Claros, norte de Minas Gerais. Métodos: estudo transversal, com coleta de dados em prontuários de ambulatório de seguimento, entrevistas com mães e, eventualmente, consultas aos prontuários hospitalares. Foram realizadas análises bivariadas entre as características sociodemográficas e clínicas e a sibilância recorrente. As variáveis associadas ao desfecho até um nível de significância de p ≤20% foram analisadas por regressão logística binária e as associações definidas pelas Odds Ratios e respectivos intervalos de confiança de 95%. Somente variáveis associadas a um nível de significância de 5% foram mantidas no modelo final de regressão logística. Resultados: entre 277 crianças estudadas, cerca de um quinto (21,3%) eram prematuros de extremo baixo peso e mais da metade (60,7%) tinha peso de nascimento abaixo de 1500 gramas. A prevalência de sibilância recorrente foi de 14,4% (IC95%=10,3-18,4). Ventilação mecânica (OR=2,12; IC95%= 1,09-4,76; p=0,030) e tempo de oxigenioterapia ≥15 dias (OR=2,49; IC95%=1,12-5,00; p=0,010) foram os fatores de risco para o evento. Conclusão: existe uma elevada prevalência de sibilância recorrente no grupo avaliado e as variáveis associadas reiteram o risco do uso prolongado de oxigenioterapia e da ventilação mecânica para recém-nascidos prematuros.

ABSTRACT

Abstract Objectives: to describe the epidemiology of invasive candidiasis in a neonatal intensive care unit. Methods: cross-sectional study that included all neonates with invasive candidiasis confirmed by blood culture from April 2015 to June 2018. Demographic, clinical and microbiological data were analyzed, comparing neonates with extreme low birth weight (ELBW) with neonates ≥ 1000g birth weight, considering a p <0.05 as statistically significant. Results: there were 38 cases of invasive candidiasis, resulting in an overall incidence of 2.5%. Twelve (32%) were ELBW neonates and 26 (68%) neonates ≥ 1000g birth weight, an incidence of 4.4% and 2.0%, respectively. Abdominal surgery was more frequent among neonates with birth weight ≥ 1000g compared to ELBW neonates (85% vs. 17%; p <0.01), as well as the median in days of antibiotics use (18 vs. 10.5; p = 0.04). The median in days of mechanical ventilation was more frequent among ELBW neonates (10 vs. 5.5; p = 0.04). The majority of Candida species were non-albicans (64%). Fatality rate was 32%. Conclusions: the incidence of invasive candidiasis among neonates with birth weight ≥ 1000g was higher than that found in the literature. This group has a higher proportion of gastrointestinal malformations that require surgery. Thus, fluconazole prophylaxis may be necessary for a broader group of neonates.


Resumo Objetivos: descrever a epidemiologia de candidíase invasiva em uma unidade de terapia intensiva neonatal. Métodos: estudo transversal que incluiu todos recém-nascidos com candidíase invasiva confirmada por hemocultura de abril de 2015 a junho de 2018. Foi analisado dados demográficos, clínicos e microbiológicos, comparando recém-nascidos de extremo baixo peso ao nascer (EBPN) com os recém-nascidos com peso ao nascer ≥1000g, considerando um valor de p<0,05 como estatisticamente significativo. Resultados: houve 38 casos de candidíase invasiva, resultando em uma incidência global de 2,5%. Doze (32%) eram neonatos de EBPN e 26 (68%) neonatos com peso ao nascer ≥1000g, resultando em uma incidência de 4,4% e 2,0%, respectivamente. A realização de cirurgia abdominal foi mais frequente nos neonatos com peso ao nascer ≥1000g em comparação com os neonatos de EBPN (85% vs. 17%; p<0,01), assim como a mediana dos dias de uso de antibióticos (18 vs. 10,5; p =0,04). Já o a mediana dos dias de ventilação mecânica foi mais frequente entre recém-nascido de EBPN (10 vs. 5,5; p = 0,04). A maioria das espécies de Candida eram não-albicans (64%). A letalidade foi de 32%. Conclusões: a incidência de candidíase invasiva entre os recém-nascidos ≥1000g ao nascer foi superior ao encontrado na literatura. Este grupo tem uma maior proporção de malformações gastrointestinais que requerem cirurgia. Assim, a profilaxia com fluconazol pode ser necessária para um grupo mais amplo de recém-nascidos.

ABSTRACT

BACKGROUND@#Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China.@*METHODS@#The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD.@*RESULTS@#A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05).@*CONCLUSION@#Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.

ABSTRACT

OBJECTIVE@#To investigate the incidence rate and risk factors for metabolic bone disease of prematurity (MBDP) in very low birth weight/extremely low birth weight (VLBW/ELBW) infants.@*METHODS@#The medical data of 61 786 neonates from multiple centers of China between September 1, 2013 and August 31, 2016 were retrospectively investigated, including 504 VLBW/ELBW preterm infants who met the inclusion criteria. Among the 504 infants, 108 infants diagnosed with MBDP were enrolled as the MBDP group and the remaining 396 infants were enrolled as the non-MBDP group. The two groups were compared in terms of general information of mothers and preterm infants, major diseases during hospitalization, nutritional support strategies, and other treatment conditions. The multivariate logistic regression analysis was used to investigate the risk factors for MBDP.@*RESULTS@#The incidence rate of MBDP was 19.4% (88/452) in VLBW preterm infants and 38.5% (20/52) in ELBW preterm infants. The incidence rate of MBDP was 21.7% in preterm infants with a gestational age of < 32 weeks and 45.5% in those with a gestational age of < 28 weeks. The univariate analysis showed that compared with the non-MBDP group, the MBDP group had significantly lower gestational age and birth weight, a significantly longer length of hospital stay, and a significantly higher incidence rate of extrauterine growth retardation (@*CONCLUSIONS@#A lower gestational age, hypocalcemia, extrauterine growth retardation at discharge, and neonatal sepsis may be associated an increased risk of MBDP in VLBW/ELBW preterm infants. It is necessary to strengthen perinatal healthcare, avoid premature delivery, improve the awareness of the prevention and treatment of MBDP among neonatal pediatricians, and adopt positive and reasonable nutrition strategies and comprehensive management measures for preterm infants.

ABSTRACT

OBJECTIVE@#To study the clinical effect of multi-oil fat emulsion for parenteral nutrition support in extremely low birth weight (ELBW) infants.@*METHODS@#A retrospective analysis was performed for 49 ELBW infants who were admitted from January 1, 2018 to July 30, 2020, with an age of ≤14 days on admission and a duration of parenteral nutrition of > 14 days. According to the type of lipid emulsion received, the ELBW infants were divided into two groups: soybean oil, medium-chain triglycerides, olive oil, and fish oil (SMOF) (@*RESULTS@#The 49 ELBW infants had a mean birth weight of (892±83) g and a mean gestational age of (28.2±2.3) weeks. There was no significant difference between the two groups in the incidence rates of hemodynamically significant patent ductus arteriosus, intraventricular hemorrhage, neonatal necrotizing enterocolitis, retinopathy of prematurity, bronchopulmonary dysplasia (BPD), grade Ⅲ BPD, sepsis, and pneumonia (@*CONCLUSIONS@#The application of multi-oil fat emulsion in ELBW infants does not reduce the incidence rate of complications, but compared with MCT/LCT emulsion, SMOF can reduce the severity of PNAC in ELBW infants.

ABSTRACT

OBJECTIVES@#To assess the growth of preterm infants up to a corrected age of 24 months, and to understand the growth trend and pattern of preterm infants.@*METHODS@#A preterm infant follow-up database was established based on the Internet Plus follow-up system. A total of 3 188 preterm infants who were born from April 2018 to April 2021 were enrolled. Their length, weight, and head circumference were recorded at birth and at the corrected ages of 1, 3, 6, 12, 18, and 24 months. The preterm infants were grouped by perinatal factors. The growth curves of these infants were plotted and compared with the International Fetal and Newborn Growth Consortium for the 21st Century (INTERGROWTH-21st) standard and World Health Organization (WHO) standard.@*RESULTS@#The weight, length, and head circumference curves of each group of preterm infants grouped by various perinatal factors all rose rapidly within the corrected age of 6 months, but the growth rate slowed down after the corrected age of 6 months. Based on the actual age for the groups of preterm infants with different gestational ages (<28 weeks, 28-31@*CONCLUSIONS@#The physical growth rate of preterm infants is faster within the corrected age of 6 months, and the growth rate slows down after the corrected age of 6 months. Preterm infants with a smaller gestational age need longer time to catch up in weight and head circumference. More attention should be paid to the physical growth of extremely preterm infants, extremely low birth weight infants, and small-for-gestational-age infants.

ABSTRACT

PURPOSE: Necrotizing enterocolitis and intestinal perforation are the most common surgical emergency in the neonatal intensive care unit. The purpose of this study is to evaluate if peritoneal drainage (PD) is beneficial in extremely low birth weight infants with intestinal perforation.METHODS: Retrospective cohort study of extremely low birth weight infants with a diagnosis of intestinal perforation. They were received primary PD (n = 23, PD group) or laparotomy (n = 13, LAP group). Laboratory and physiologic data were collected and organ failure scores calculated and compared between preprocedure and postprocedures. Data were analyzed using appropriated statistical tests.RESULTS: Between January 2005 and December 2015, 13 infants (male:female = 9:4) received laparotomy. Of 23 infants (male:female = 16:7) received PD, 20 infants received subsequent laparotomy. There were no demographic differences between PD and LAP groups. And there were no differences in total organ score in either group (PD, P = 0.486; LAP, P = 0.115). However, in LAP group, respiratory score was statistically improved between pre- and postprocedure organ failure score (P = 0.02). In physiologic parameter, PD group had a statistically worsening inotropics requirement (P = 0.025). On the other hand, LAP group had a improvement of PaO₂/FiO₂ ratio (P = 0.01).CONCLUSION: PD does not improve clinical status in extremely low birth weight infants with intestinal perforation.

ABSTRACT

To investigate the incidence and risk factors of extrauterine growth retardation (EUGR) in very low birth weight infants (VLBWI). This prospective, multicenter observational cohort study was conducted based on Shandong Neonatal Network (SNN). The clinical data of the VLBWI (=1 051), who were admitted to 27 neonatal intensive care units from January 1, 2018 to December 31, 2018, were collected and analyzed. According to the weight at discharge or 36 weeks of postmenstrual age, all the enrolled VLBWI were assigned into EUGR group and non-EUGR group. Univariate and multivariate logistic regression analyses were used to detect the risk factors for EUGR in preterm small for gestational age (SGA) and non-SGA infants. A total of 1 051 VLBWI were enrolled, with 51.7% (543/1 051) male. The incidence of EUGR in the whole group was 60.7% (638/1 051), and were 78.3% (90/115) and 46.9% (53/113) in extremely low birth weight infant (ELBWI) and extremely preterm infants (EPI), respectively. The incidence of EUGR in SGA and non-SGA infants were 87.6% (190/217) and 53.7% (448/834), respectively. Logistic regression analysis showed that, withholding feeds (1.531, 1.237, 95: 1.180-1.987, 1.132-1.353, both <0.01) and time to achieve full enteral feeding (1.090, 1.023, 95: 1.017-1.167, 1.002-1.045, 0.014, 0.034) were independent risk factors of EUGR in both SGA and non-SGA infants. For SGA infants, cesarean delivery was an independent risk factor for EUGR (8.147, 95: 2.127-31.212, 0.002); while for non-SGA infants, hypertensive disorders during pregnancy (2.572, 95: 1.496-4.421, 0.001) and the duration of invasive ventilation (1.050, 95: 1.009 - 1.092, 0.016) were independent risk factors of EUGR. Besides, moderate and severe bronchopulmonary dysplasia (2.241, 95: 1.173-4.281, 0.015), necrotizing enterocolitis (5.633, 95: 1.333-23.796, 0.019) and retinopathy of prematurity (2.219, 95: 1.268-3.885, 0.005) were associated with EUGR. The incidence of weight-defined EUGR is high in VLBWI, especially in preterm SGA infants. Avoiding delaying feeds after birth and achieving full enteral feeding early may reduce the incidence of EUGR.

ABSTRACT

OBJECTIVE@#To investigate the current status of antibiotic use for very and extremely low birth weight (VLBW/ELBW) infants in neonatal intensive care units (NICUs) of Hunan Province.@*METHODS@#The use of antibiotics was investigated in multiple level 3 NICUs of Hunan Province for VLBW and ELBW infants born between January, 2017 and December, 2017.@*RESULTS@#The clinical data of 1 442 VLBW/ELBW infants were collected from 24 NICUs in 2017. The median antibiotic use duration was 17 days (range: 0-86 days), accounting for 53.0% of the total length of hospital stay. The highest duration of antibiotic use was up to 91.4% of the total length of hospital stay, with the lowest at 14.6%. In 16 out of 24 NICUs, the antibiotic use duration was accounted for more than 50.0% of the hospitalization days. There were 113 cases with positive bacterial culture grown in blood or cerebrospinal fluid, making the positive rate of overall bacterial culture as 7.84%. The positive rate of bacterial culture in different NICUs was significantly different from 0% to 14.9%. The common isolated bacterial pathogens Klebsiella pneumoniae was 29 cases (25.7%); Escherichia coli 12 cases (10.6%); Staphylococcus aureus 3 cases (2.7%). The most commonly used antibiotics were third-generation of cephalosporins, accounting for 41.00% of the total antibiotics, followed by penicillins, accounting for 32.10%, and followed by carbapenems, accounting for 13.15%. The proportion of antibiotic use time was negatively correlated with birth weight Z-score and the change in weight Z-score between birth and hospital discharge (r=-0.095, -0.151 respectively, P<0.01), positively correlated with death/withdrawal of care (r=0.196, P<0.01).@*CONCLUSIONS@#Antibiotics used for VLBW/ELBW infants in NICUs of Hunan Province are obviously prolonged in many NICUs. The proportion of routine use of third-generation of cephalosporins and carbapenems antibiotics is high among the NICUs.

ABSTRACT

Mothers increasingly mention poor health of the newborn child as the reason for abandoning the child. One of the factors causing the unsatisfactory state of the child's health is the child's premature birth, a little or long before the due date. According to the data of most developed countries of the world, from 5% to 10% of children in the general population are born prematurely. In the Russian Federation, these premature births amount for around 75% of infant mortality. Moreover, the most vulnerable ones among premature infants are children with extremely low and very low body weight. In this regard, the goal of the study has been formulated to assess the state of health of the children born with very low and extremely low body weight and left without parental care. Material and Methods. For this, a retrospective analysis of the labor and delivery records has been conducted for 182 newborns abandoned by mothers in maternity hospitals in the Chelyabinsk region in the period from 2012 to 2017. Results and discussion. Over the study period, the average proportion of newborns with low and extremely low body weight was as follows: 12.1% in the big urban center, 12.0% in urban districts and 12.7% in rural municipalities of the total number of early social orphans. The proportion of newborns with very low body weight was 69.0%; 31.0% had extremely low body weight. The smallest of the examined infants was a newborn with a birth weight of 840 grams. It was found that children born with extremely low and very low body weight had from two to three pathologies already at birth. Conclusion. The identified risk factors for the birth of premature babies are the following: extragenital diseases of the mother, complicated obstetric and gynecological history, infectious diseases of the mother. A high proportion of newborns with very low and extremely low body weight (12.0-12.7%) among abandoned children indicates that the latter are at risk for this pathology.

O objetivo deste estudo foi investigar a qualidade de vida (QV) de crianças que nasceram com muito ou extremo baixo peso, na perspectiva das próprias crianças e de seus responsáveis, e identificar se há diferenças entre esses relatos. Estudo quantitativo, com amostra composta por crianças de 3 a 7 anos e seus responsáveis, advindos de um serviço de follow-up de instituição pública. Foi utilizada a Escala de Qualidade de Vida da Criança. Obteve-se escore médio de 49,75 (DP = 5,97) na avaliação das crianças e de 48,90 (DP = 6,54) na de seus responsáveis. A QV foi considerada prejudicada por 25% das crianças e por 37,5% dos responsáveis. Foram encontradas fraca correlação e pobre concordância entre os relatos das crianças e dos respectivos responsáveis. É importante avaliar a QV na percepção da criança e dos responsáveis considerando-se que pais e crianças forneceram perspectivas diferentes, o que pode direcionar a assistência à família na atenção primária.


This study aims to evaluate the quality of life (QoL) of children born with very low or extremely low birth weight from their point of view and their guardians' point of view, and at identifying if there are differences between the reports. It is a quantitative study with a sample of 3-7 years-old children and their guardians selected at a follow-up service on a public institution. The Quality of Life Scale for Children was used. An average score 49,75 (DP = 5,97) was achieved in children's evaluation and 48,90 (DP = 6,54) in their proxies' evaluation. The QoL was considered impaired by 25% of children and 37,5% of their guardians. There was a weak correlation and a poor agreement between children and guardians' reports. It is important to evaluate the QoL reports of children and guardians considering that parents and children provided different views, which may direct assistance to the family in primary health care.

ABSTRACT

PURPOSE: This study aimed to evaluate the clinical and radiologic findings suggestive of spontaneous intestinal perforation (SIP) in extremely-low-birth-weight infants (ELBWIs) with persistent gasless abdomen, and to investigate the usefulness of abdominal ultrasonography for the diagnosis of SIP. METHODS: In total, 22 infants with birth weights less than 1,000 g who showed persistent gasless abdomen on simple abdominal radiography were included. Perinatal, neonatal, and perioperative clinical findings were retrospectively reviewed, and the risk factors for intestinal perforation were evaluated. Abdominal sonographic findings suggestive of intestinal perforation were also identified, and postoperative short-term outcomes were evaluated. RESULTS: In total, eight of the 22 infants (36.4%) with gasless abdomen had SIP. The number of infants with patent ductus arteriosus who were treated with intravenous ibuprofen or indomethacin was significantly higher in the SIP group than in the non-SIP group (P<0.05). Greenish or red gastric residue, abdominal distension, or decreased bowel sound were more frequent in infants with SIP (P<0.05), in addition to gray or bluish discoloration of abdomen, suggestive of meconium peritonitis (P<0.05). Pneumoperitoneum on simple abdominal radiography was found in only one of the eight infants (12.5%) with SIP. Intramural echogenicity and echogenic extramural material on abdominal ultrasonography were exclusively observed in infants with SIP. Four infants (50%) with SIP died after surgical intervention. CONCLUSION: Intestinal perforation may occur in ELBWIs with gasless abdomen. As intramural echogenicity and extraluminal echogenic materials on abdominal ultrasonography are indicative of SIP, this technique could be useful for diagnosing SIP.

ABSTRACT

PURPOSE: This study was aimed to investigate the effect of early phosphorus intake on respiratory distress in extremely low-birth-weight infants (ELBWIs) with a high incidence of hypophosphatemia. METHODS: We performed a retrospective study to target 164 ELBWIs admitted to the neonatal intensive care unit in Seoul National University Children's Hospital. Birth characteristics, nutritional intake, and electrolyte levels during the first week were investigated as predictors that would affect the clinical outcomes. The correlations among invasive ventilation at postnatal age of 2 weeks, moderate-to-severe bronchopulmonary dysplasia (BPD), and phosphorous intake were analyzed. RESULTS: Hypophosphatemia (phosphorus level <4 mg/dL) was observed in 72.0% of the subjects. The rates of invasive ventilation (P=0.001) and moderate-to-severe BPD (P=0.005) were significantly lower in the high phosphorus intake group (≥0.7 mM/kg/day) than in the low phosphorus intake group (<0.7 mM/kg/day). Phosphorus intake during the first week was a significant factor affecting invasive ventilation at 2 weeks of age (adjusted odds ratio [OR], 8.212; 95% confidence interval [CI], 2.256 to 28.896; P=0.001) and moderate-to-severe BPD (adjusted OR, 3.402; 95% CI, 1.274 to 9.084; P=0.015). CONCLUSION: Early insufficient phosphorus intake confers a significantly higher risk with invasive ventilation at 2 weeks of age and moderate-to-severe BPD. Therefore, early sufficient phosphorus supply may improve respiratory outcomes in ELBWIs.

ABSTRACT

To analyze clinical characteristics and risk factors of very low birth weight and extremely low birth weight infants with bronchopulmonary dysplasia (BPD). A retrospective epidemiological study was performed in 768 neonates (376 males) with birth weights<1 500 g and gestational age ≤ 34 weeks who survived ≥28 days. Clinical data were obtained from the multi-center clinical database of neonatal intensive care units (NICU) in 19 hospitals of Jiangsu Province between January 1, 2017 and December 31, 2017. These infants were divided into non-BPD group and BPD group according to BPD diagnositic criteria. Clinical features and potential risk factors were compared between groups with Chi-square test or nonparametric test. Risk factors for BPD were analyzed with Logistic regression analysis. Among the total of 768 eligible neonates, 577 without BPD, 191 with BPD (24.9%). Mild, moderate and severe BPD accounted for 73.3% (140/191), 23.6% (45/191) and 3.1% (6/191) of all BPD cases respectively. There were significant differences in the average gestational age (29 (28, 30) 30 (29, 31) weeks) or the average birth weight (1 170 (990, 1 300) 1 300 (1 160, 1 400) g) between BPD group and non-BPD group (-9.959,-7.202, both 0.000). The incidences of BPD in the infants with gestational age of<28 weeks, 28-31 weeks and 32-34 weeks were 51.7% (46/89), 24.8% (139/561), 5.1% (6/118) respectively. The incidences of BPD in infants with birth weigh1 000 g, 1 000- 1 249 g and 1 250-1 500 g were 62.3% (48/77), 25.9% (70/270) and 17.3% (73/421) respectively. Proportion of male (55.5% (106/191) 46.8% (270/577)), rate and length of conventional mechanical ventilation (48.7% (93/191) 14.9% (86/577), 120 (72, 259) 80 (29, 144)h), initial inhaled oxygen concentration and maximum inhaled oxygen concentration (0.35 (0.30, 0.40) 0.30(0.25, 0.40), 0.40 (0.30, 0.50) 0.30 (0.30, 0.40)) and volume of red blood cell transfusion (53(30, 90) .38(28, 55) ml) were higher in BPD group than in non-BPD group (χ(2)=4.350, 91.640, -3.557, -2.848, -3.776, -4.677, all 0.05). Rate of continuous positive airway pressure (12.6%(24/191) 19.4%(112/577)) during neonatal resuscitation in delivery room was lower in BPD group than that in non-BPD group (χ(2)=4.614, 0.032). The incidences of complications in BPD group including severe asphyxia, neonatal respiratory distress syndrome (NRDS), persistent pulmonary hypertension in newborns (PPHN), patent ductus arteriosus, anemia of prematurity, early onset sepsis, clinical sepsis and ventilator associated pneumonia were higher than that in non-BPD group (15.2%(29/191) 4.5% (26/577), 91.1% (174/191) 56.7% (327/577), 2.6% (5/191) 0.2% (1/577), 43.5% (83/191) 34.2% (197/577), 88.0% (168/191) 58.8% (339/577), 15.7% (30/191) 9.9% (57/577), 42.9% (82/191) 18.6% (107/577), 14.1% (27/191) 2.3% (13/577); χ(2)=24.605, 74.993, 9.167, 5.373, 61.866, 4.557, 43.149, 34.315, all 0.05). Multivariate logistic regression analysis showed that NRDS (4.651, 95: 1.860-11.625), clinical sepsis (1.989, 95: 1.067-3.708), ventilator associated pneumonia (3.155, 95: 1.060-9.388), conventional mechanical ventilation (2.298, 95: 1.152-4.586), and volume of red blood cell transfusion (1.013, 95: 1.002-1.024) were risk factors of BPD. BPD is more common in very low birth weight infants of male with gestational age less than 32 weeks. Using CPAP in the delivery room, active treatment of NRDS, preventing nosocomial infection, and reducing invasive ventilation and red blood cell transfusion may decrease the incidence of BPD.

ABSTRACT

To investigate the incidence and risk factors of severe intraventricular hemorrhage (IVH) in very low birth weight infants (VLBWI) and extremely low birth weight infants (ELBWI). The data were from "reduction of infection in Chinese neonatal intensive care units using the evidence-based practice for improving quality"study, which prospectively enrolled infants with gestational age less than 34 weeks, and were admitted within the first seven days of life in 25 tertiary neonatal intensive care units from May 2015 to April 2018. Clinical data of VLBWI and ELBWI, who had neuroimage examination during the hospitalization, were retrospectively extracted from the standard database and were secondarily-analyzed. Patients with congenital malformations were excluded. A total of 8 835 VLBWI and ELBWI were enrolled with 52.6% (4 643 cases) male, who were divided into severe IVH group and without IVH or mild IVH group. Descriptive statistics were used to analyze the incidence of severe IVH. Comparison between two groups and risk factors were analyzed with univariate and multivariate Logistic regression analysis. The incidence of severe IVH in the 8 835 infants was 7.4% (650/8 835). And the incidences of severe IVH in ELBWI and preterm infants with gestational age ≤28 weeks were 13.5% (160/1 185) and 13.1% (368/2 800), respectively. The incidences of severe IVH in preterm infants with birth weight<750 g, 750-999 g, 1 000-1 249 g, 1 250-1 499 g were 21.1% (31/147), 12.4% (129/1 038), 8.3% (246/2 966) and 5.2% (244/4 684), respectively; and were 25.2% (55/218), 12.1% (313/2 582), 5.2% (243/4 649) and 2.8% (39/1 386) in the preterm infants with gestational age<26 weeks, 26-28(+6) weeks, 29-31(+6) weeks, 32-33(+6) weeks, respectively. Logistic regression analysis revealed that gestation age (0.752, 95: 0.687-0.823, 0.000) and cesarean delivery (0.733, 95: 0.592-0.907, 0.004) decreased the risks of severe IVH; while Apgar score ≤3 at 5 minutes (1.897, 95: 1.194-3.013, 0.007), use of invasive mechanical ventilation within the first week (1.499, 95: 1.207-1.862, 0.000), use of inotropic medications within the first week (2.093, 95: 1.724-2.541, 0.000) increased the risks of severe IVH. The incidence of severe IVH is still significantly high among VLBWI and ELBWI. Low gestation age, non-cesarean delivery, Apgar score ≤3 at 5 minutes, use of invasive mechanical ventilation and inotropic medications within the first week of life will increase the risk of severe IVH.

ABSTRACT

OBJECTIVE@#To study the clinical features and pathogenic bacteria of late-onset sepsis (LOS) in very low birth weight (VLBW) and extremely low birth weight (ELBW) infants.@*METHODS@#Among the VLBW/ELBW infants with a gestational age of <32 weeks who were admitted to the hospital between January 2012 and December 2016, those with LOS were enrolled as the LOS group, and those without sepsis were matched for the infant with LOS in gestational age were enrolled as the control group. According to the presence or absence of in-hospital death, the LOS group was further divided into a death subgroup and a survival subgroup. Risk factors for LOS, clinical features, distribution of pathogenic bacteria, drug resistance, and high-risk factors for LOS-related death were analyzed.@*RESULTS@#A total of 513 VLBW/ELBW infants were enrolled, and there were 65 infants in the LOS group and 130 in the control group. The incidence rate of LOS was 12.7%. In the LOS group, 6 infants died and 59 survived. Compared with the control group, the LOS group had a significantly lower birth weight (P<0.05) and significantly longer indwelling time of peripherally inserted central catheter (PICC), duration of mechanical ventilation, and length of hospital stay (P<0.05). Compared with the control group, the LOS group had a significantly higher proportion of small-for-gestational-age infants, infants undergoing mechanical ventilation, infants with neonatal necrotizing enterocolitis, or infants who died (P<0.05). Low birth weight, small-for-gestational-age infant, and long indwelling time of PICC were independent risk factors for LOS in VLBW/ELBW infants (OR=1.396, 2.550, and 1.068 respectively, P<0.05). Purulent meningitis was an independent risk factor for LOS-related death in VLBW/ELBWIs infants (OR=13.443, P<0.05). A total of 65 strains of pathogenic bacteria were cultured in the LOS group, among which there were 39 strains (60%) of Gram-negative bacteria, including 15 strains producing extended spectrum beta-lactamases (ESBLs), and antibiotics were applied for 67% (10/15) of the ESBL strains within 2 weeks before the onset of LOS. The rate of antibiotic use for ESBL strains was significantly higher than that for non-resistant strains [67% (10/15) vs 29% (7/24); P<0.05].@*CONCLUSIONS@#Low birth weight, SGA infant, and long indwelling time of PICC are independent risk factors for LOS in VLBW/ELBW infants, and death tends to occur in LOS infants with purulent meningitis. Most pathogenic bacteria of LOS are Gram-negative bacteria, and use of antibiotics within 2 weeks before disease onset may increase the risk of ESBL strain infection.

ABSTRACT

OBJECTIVE@#To examine blood concentrations of free carnitine (FC) in preterm infants with different gestational ages (GA) and birth weights (BW).@*METHODS@#A total of 3 368 preterm infants were enrolled as subjects. According to GA, they were divided into extremely preterm birth (EPTB) group (GA <28 weeks; n=39), very preterm birth (VPTB) group (28 ≤GA <32 weeks; n=405), moderately preterm birth (MPTB) group (32 ≤GA <34 weeks; n=507), and late preterm birth (LPTB) group (34 ≤GA <37 weeks; n=2 417); according to BW, they were divided into extremely low birth weight (ELBW) group (BW <1 000 g; n=36), very low birth weight (VLBW) group (1 000 g ≤BW <1 500 g; n=387), low birth weight (LBW) group (1 500 g ≤BW <2 500 g; n=1 873), and normal birth weight (NBW) group (2 500 g ≤ BW <4 000 g; n=1 072). Blood concentrations of FC were measured between 72 hours and 7 days after birth.@*RESULTS@#The EPTB and VPTB groups had significantly higher FC concentrations than the MPTB and LPTB groups (P<0.05), and the MPTB group had significantly higher FC concentrations than the LPTB group (P<0.05). The lower limit of the 95% medical reference range of FC increased with the reduction in GA. The ELBW and VLBW groups had significantly higher FC concentrations than the LBW and NBW groups (P<0.05). The LBW group had significantly higher FC concentrations than the NBW group (P<0.05). The lower limit of the 95% medical reference range of FC increased with the reduction in BW.@*CONCLUSIONS@#There is a significant increase in blood FC concentrations in very/extremely preterm infants and very/extremely low birth weight infants, and tend to decrease with the increases in GA and BW.
