Effect of family integrated ward on maintaining optimal oxygen saturation targets in premature infants with bronchopulmonary dysplasia: a single-center retrospective cohort study / 中国新生儿科杂志

Objective:To study the application effect of family integrated ward in maintaining the optimal target pulse oxygen saturation (SpO 2) in premature infants with bronchopulmonary dysplasia (BPD). Methods:This was a retrospective cohort study. Premature infants with BPD admitted to the neonatal intensive care unit of Children's Hospital of Nanjing Medical University from June 2019 to January 2022 were enrolled. Based on whether to stay in family integrated ward and implement family integrated care (FICare), these premature infants were divided into the family ward group and the control group. The ratio of optimal target SpO 2 within 24 h before discharge, the duration of home oxygen therapy, and ratio of readmission due to respiratory disease within 6 months after discharge were analyzed between the two groups. Results:During the study period, a total of 167 premature infants with BPD were admitted, including 101 in the family ward group and 66 in the control group. Compared with the control group, the family ward group showed a higher proportion of achieving the optimal target SpO 2 within 24 h before discharge (58.0% vs. 24.0%), shorter duration for home oxygen therapy (7.0 d vs. 12.0 d), and a lower readmission rate within 6 months after discharge (16.5% vs. 30.2%), which had statistically significant difference (all P<0.05). Further regression analysis showed that participating in the family integrated ward significantly reduced the demand for home oxygen therapy and the duration of home oxygen therapy, but had no significant impact on the readmission rate within 6 months after discharge. Conclusions:Family integrated ward can effectively increase the proportion of achieving the optimal target SpO 2 for premature infants with BPD within 24 h before discharge, reduce the demand for home oxygen therapy, and shorten the time of home oxygen therapy after discharge, which is beneficial for improving the living quality of premature infants with BPD.

Clinical application and complication analysis of umbilical arterial catheterization in premature infants / 中国新生儿科杂志

Objective:To study the clinical application and complications of umbilical arterial catheterization (UAC) in premature infants.Methods:From January 2021 to December 2022, premature infants with UAC successfully inserted in NICU of our hospital were enrolled. According to birth weight (BW), the infants were assigned into three groups: <1 000 g, 1 000~1 499 g and ≥1 500 g. The perinatal data, UAC usage, UAC-related complications and risk factors of UAC-related complications were retrospectively analyzed.Results:A total of 39 premature infants received UAC, with gestational age 29.3(27.3, 30.4) weeks and BW 1 100 (900, 1 310) g. The insertion length (IL) of UAC was calculated using the average value of two formulas: a, IL (cm) =4×BW (kg) +7; and b, IL(cm) =3×BW (kg)+9. The accuracy of tube end position was determined using chest/abdomen radiography. 30(76.9%) cases had accurate position, 6(15.4%) had higher position and 3(7.7%) had lower position. The proportion of appropriately positioned tube end in <1 000 g, 1 000~1 499 g and ≥1 500 g groups were 80.0%, 76.5% and 71.4%, respectively, without statistically significant differences ( P>0.05) .No significant differences existed among the three groups in UAC duration and UAC routinely removal rate ( P>0.05). 9 cases (23.1%) of UAC were removed for specific reasons, including 4 cases of arterial spasm, 2 cases of withdrawal of treatment, 1 case of tube end displacement, 1 case of abdominal distension and 1 case of death. 21 cases received 1 U/ml heparin (0.9%NaCl solution) 0.5~1 ml/h arterial infusion. 23.8% (5/21) had hypernatremia and the level of sodium became normal after reducing the concentration of NaCl solution. Arterial vasospasm occurred in 4 patients with skin color changes of one side of the lower extremities. After UAC removal, the skin color returned to normal. Conclusions:UAC is helpful and safe for preterm infants, however, its complications should be alerted to.

The correlation between adverse outcomes during hospitalization and early postnatal weight loss in extremely premature infants / 中国新生儿科杂志

Objective:To study the correlation between adverse clinical outcomes and early postnatal weight loss(representing the results of fluid management) during hospitalization in extremely premature infants(EPIs).Methods:From January 2019 to March 2023, EPIs (gestational age (GA)<28 weeks) admitted to neonatal intensive care unit(NICU) of our hospital were retrospectively analyzed. According to weight loss (WL) within the first 3 d after birth, the infants were assigned into no-WL group, WL<6% group, WL 6%-10% group and WL>10% group. The following items were compared among the four groups: fluid intake within the first 7 d after birth, the incidences of hemodynamically significant patent ductus arteriosus (hsPDA), PDA requiring surgical ligation, duration of invasive mechanical ventilation, ≥stage II necrotizing enterocolitis(NEC), grade 3-4 intraventricular hemorrhage(IVH), moderate bronchopulmonary dysplasia (BPD), severe BPD, mortality rates and total length of hospital stay.Results:A total of 119 EPIs were enrolled, including 41 in no-WL group, 22 in WL<6% group, 31 in WL 6%-10% group and 25 in WL>10% group. Among the four groups, no significant differences existed in fluid intake on d1 and d5-d7 after birth ( P>0.05). WL 6%-10% and >10% groups had significantly lower fluid intake during d2-d4 than no-WL group ( P<0.05).On d4, WL 6%-10% and >10% groups had lower fluid intake than WL <6% and no-WL groups( P<0.05).WL 6%-10% and >10% groups showed lower incidences of hsPDA than no-WL group ( P<0.05).WL>10% group had lower incidences of ≥stage II NEC, moderate BPD, shorter duration of invasive mechanical ventilation and total hospital stay than no-WL group( P<0.05). No significant differences existed in the incidences of PDA requiring surgical ligation, grade 3-4 IVH, severe BPD and mortality rates among the four groups ( P>0.05). Conclusions:For EPIs, a certain degree of WL within the first 3 d after birth is beneficial to reduce the incidences of hsPDA, NEC, moderate BPD, duration of invasive mechanical ventilation and total hospital stay. Focusing on body weight is helpful for a more optimal fluid management strategy in the early postnatal period.

Factors Affecting Early-onset Sepsis in Preterm Infants and Construction of Nomogram Model / 医学研究杂志

Objective To analyze the factors influencing early-onset sepsis in preterm infants and construct nomogram model.Methods A total of 124 neonates with premature sepsis admitted to Shanxi Children's Hospital(Shanxi Maternal and Child Health Hos-pital)from January 2020 to December 2021 were collected.According to gestational age,the neonates were divided into premature group(n=33)and full-term group(n=91),and the clinical characteristics of the two groups were compared,and nomogram model was es-tablished to internally validate the predictiveness and accuracy of the model.Results Compared with the full-term group,the proportion of females in premature group was higher(x2=7.147,P＜0.05),the 1min Apgarscore in premature group was lower(x2=-3.398,P＜0.05),the proportion of perinatal mothers with pregnancy complications in premature group was higher(x2=7.846,P＜0.05),the incidence of pneumonia and poor response in preterm infants of premature group were higher(x2=18.210,P＜0.05;x2=14.814,P＜0.05),but the incidence of jaundice in premature group was lower(x2=10.400,P＜0.05).Multivariate Logistic regression analysis showed that female and pneumonia were risk factors for early-onset sepsis in preterm infants(P＜0.05).The results of the nomogram model showed that the C-index of the model was 0.886.The predicted incidence was generally consistent with the actual incidence,the area under the receiver operator characteristic curve was 0.886,and the decision curve showed a high net benefit value at threshold proba-bilities of 4％-100％.Conclusion Female,preterm infants with pneumonia have a higher risk of early-onset sepsis.The nomogram model of premature sepsis constructed in this study has high clinical value and can provide a reference basis for clinical prevention of early-onset sepsis in preterm infants.

Influencing factors for healthcare-associated infection in premature infants in a maternal and child health hospital:2016-2021 / 中国感染控制杂志

Objective To understanding the current situation and influencing factors of healthcare-associated infec-tion(HAI)in premature infants,provide theoretical and practical basis for the prevention and control of HAI in pre-mature infants.Methods Premature infants who were admitted to the neonatal ward of a hospital from January 2016 to December 2021 were investigated and analyzed retrospectively.Medical records of premature infants were consulted to collect basic information as well as diagnosis and treatment information of premature infants during hos-pitalization.Results A total of 3 559 premature infants were included in analysis,including 1 964 males and 1 595 females.The average birth weight was(2 108.66±631.17)g.109(3.06％)infants had HAI infection.The main infection types were lower respiratory tract infection(44.04％),bloodstream infection(28.44％),and gastrointestinal tract infection(14.68％).38 strains of HAI-related pathogens were detected,including 33 strains(86.84％)of Gram-negative bacteria,3 strains of Gram-positive bacteria,and 2 strains of fungi.The main isolated pathogens were Enterobacter aero genes(28.95％)and Klebsiella pneumoniae(28.95％).Univariate and unconditional multivariate logistic regression analysis showed that amniotic fluid contamination,birth weight＜2 500 g,ventilator use,and central venous catheterization were independent risk factors for HAI in premature infants(OR values were 2.424,3.805,3.776,5.412,respectively,all P＜0.05).Cesarean section was a protective factor for HAI in premature in-fants(OR=0.362,P＜0.05).Conclusion Premature infants have a high risk of HAI and multiple influencing fac-tors.Clinical attention should be paid,evidence-based prevention and control measures should be actively adopted to reduce exposure to risk factors and protect the health of premature infants.

Design and application of a warming fixation device for premature infants / 中华危重病急救医学

Objective:A warming fixation device for premature infants was made and its clinical application effect was discussed.Methods:The warming fixation device for premature infants was designed and used in clinic. Sixty premature infants admitted to the neonatal ward of Baoding Hospital, Beijing Children's Hospital, Capital Medical University from January to June 2022 were selected as the control group, and 60 premature infants admitted from July to December 2022 were selected as the experimental group. In the control group, umbilical vein catheterization or central vein catheterization were performed using Astro Boy heating box, restraint band or artificial restraint. The preterm infants in the experimental group were radiated into the Astro Boy warm box with self-designed preterm warming fixation device for catheterization. The time of catheterization, the number of limb protrusion, the number of participants in catheterization operation, and the body temperature from 20 minutes of catheterization operation to the end of catheterization operation were recorded in the two groups. The frequency of hypothermia (< 36.5?℃) was calculated, and the differences in various indexes between the two groups were compared.Results:① The warming fixation device for premature babies consists of two parts: warm sleeping bag and soft pad. The warm sleeping bag includes 4 parts: head, arm, chest and abdomen, and lower limbs. The chest and abdomen were designed with rectangular covering cloth, which can be opened to facilitate umbilical vein puncture for premature infants. There were 3 groups of restraint belts on the rectangular soft pad, which can respectively fix the arms, chest and abdomen of the warm sleeping bag and the lower limbs. During the catheterization operation, use Velcro to secure the warm sleeping bag to the cushioned surface, and select the area of exposed skin according to the piercing site. ② There were no significant differences in gender, body weight and gestational age between the experimental group and the control group [male: 48.3% vs. 46.7%, body weight (kg): 1.86±0.06 vs. 1.82±0.06, gestational age (weeks): 31.33±0.31 vs. 32.25±0.34, all P > 0.05]. Compared with the control group, the catheterization time of experimental group was significantly shortened (minutes: 21.30±0.43 vs. 30.02±0.64, P < 0.01), the number of limb protrusion was significantly reduced (0 time: 70.0% vs. 33.3%, 1 time: 26.7% vs. 50.0%, P < 0.01), and the number of participants in catheterization operation was significantly reduced (people: 1.77±0.06 vs. 2.37±0.06, P < 0.01). The frequency of hypothermia in experimental group was significantly lower than that in the control group [6.12% (6/98) vs. 26.50% (31/117), χ2 = 15.536, P < 0.01]. Conclusion:The warming fixation device for premature infants is convenient to use, which can effectively shorten the tube placement time, save human resources, and reduce the incidence of hypothermia in premature infants.

Energy Dense Feeding in Premature Infants and Its’ Associated Outcomes (Pemakanan Tumpat Tenaga dalam Bayi Pramatang dan Kesan Berkaitan) / Jurnal Sains Kesihatan Malaysia

@#COVID-19 infection in pregnant mothers is associated with higher risk of intrauterine growth retardation and premature births. Very low birth weight infants are more susceptible to neurodevelopmental and chronic respiratory problems. An infant delivered at 33 weeks via caesarean section to a COVID-19 Stage 5A positive mother, weighing 1.43kg at birth. She was kept nil by mouth with parenteral nutrition (PN) support since day five of life until referred to dietitian on day 22 of life for enteral nutrition (EN) establishment. Feeding was administered intermittently via oro-gastric Ryles tube. She was kept under non-invasive ventilation (NIV) mode and had difficulty in weaning from ventilation, leading to slow feeding progress. Initially, enteral trophic feeding was administered using premature infant formula fortified with modular products. In the later stage of feeding, modular products were tapered off and the formula was concentrated. Frequency of bowel output when using fortified formula is lesser compared to when using concentrated and supplemented formula. There is no significant difference in renal profile observed in both stages of feeding. Increasing energy intake using easily digestible sources is preferable as opposed to concentrating feeds even further due to concerns about osmolality and excess administration of other solutes. Intermittent bolus feeding mode may have an effect on dependency on oxygen since intermittent feeds can decrease tidal volume, minute ventilation and dynamic compliance. Additional research is necessary to establish optimal caloric density and nutritional compositions of feedings, feeding mechanisms and its’ effect on feeding tolerance.

Early-onset neonatal sepsis as a risk factor for peri-intraventricular hemorrhage in premature infants / Sepse precoce como fator de risco para hemorragia peri-intraventricular em prematuros

ABSTRACT Objective: To assess early-onset sepsis as a risk factor of peri-intraventricular hemorrhage in premature infants born at less than or equal to 34 weeks' gestation and admitted to a neonatal intensive care unit (NICU). Methods: This retrospective cohort study included premature patients born at less than or equal to 34 weeks' gestation who were admitted to the NICU of a tertiary hospital in southern Brazil, and born from January 2017 to July 2021. Data were collected from patients' medical records. Early-onset sepsis was measured according to the presence or absence of diagnosis within the first 72 hours of life, whereas the outcome, peri-intraventricular hemorrhage, was described as the presence or absence of hemorrhage, regardless of its grade. Results: Hazard ratios were calculated using Cox regression models. A total of 487 patients were included in the study, of which 169 (34.7%) had some degree of peri-intraventricular hemorrhage. Early-onset sepsis was present in 41.6% of the cases of peri-intraventricular hemorrhage, which revealed a significant association between these variables, with increased risk of the outcome in the presence of sepsis. In the final multivariate model, the hazard ratio for early-onset sepsis was 1.52 (95% confidence interval 1.01-2.27). Conclusion: Early-onset sepsis and the use of surfactants showed to increase the occurrence of the outcome in premature children born at less than or equal to 34 weeks' gestation. Meanwhile, factors such as antenatal corticosteroids and gestational age closer to 34 weeks' gestations were found to reduce the risk of peri-intraventricular hemorrhage.

RESUMO Objetivo: O objetivo do presente trabalho foi avaliar a sepse precoce como fator de risco para hemorragia peri-intraventricular (HPIV) em prematuros com 34 semanas ou menos, admitidos em Unidade de Terapia Intensiva (UTI) Neonatal. Métodos: Este estudo de coorte retrospectivo incluiu pacientes prematuros com 34 semanas ou menos, que receberam alta da UTI Neonatal de hospital terciário, no sul do Brasil, nascidos no período de janeiro de 2017 a julho de 2021. Os dados foram coletados por meio dos prontuários desses pacientes. A sepse precoce foi mensurada conforme a presença ou a ausência do diagnóstico nas primeiras 72 horas de vida. Já o desfecho, hemorragia peri-intraventricular, foi descrito conforme a presença ou ausência da hemorragia, independentemente do grau. Resultados: Hazard ratios (HR) foram calculados por meio de modelos de regressão de Cox. Foram incluídos no estudo 487 pacientes. Destes, 169 (34,7%) apresentaram algum grau de hemorragia peri-intraventricular. A sepse precoce esteve presente em 41,6% dos casos de hemorragia peri-intraventricular e apresentou associação significativa, elevando o risco do desfecho quando presente. No modelo multivariável final, o HR para a sepse precoce foi de 1,52 (intervalo de confiança de 95% — IC95% 1,01-2,27). Conclusão: Sepse precoce e uso de surfactante demonstraram aumentar a ocorrência do desfecho em crianças prematuras até 34 semanas, enquanto fatores como corticoide antenatal e idades gestacionais mais próximas a 34 semanas mostraram reduzir o risco de ocorrência hemorragia peri-intraventricular.

Cross-cultural adaptation of the Neonatal Medical Index (NMI) to Brazil / Adaptação transcultural do Neonatal Medical Index (NMI) para o Brasil

ABSTRACT Objective: To perform a cross-cultural adaptation and assess the content validity of the Neonatal Medical Index (NMI) for the Brazilian context. Methods: The cross-cultural adaptation was completed in six steps, including translation, synthesis of translations, back translation, submission to an expert committee, testing of the prefinal version, and appraisal by the original author. The expert committee assessed the equivalence between versions based on the percentage of agreement, and content validity was evaluated using the content validity index (CVI) for each item of the scale (I-CVI) and for the overall scale (S-CVI) in terms of representativeness and clarity. Participants of the prefinal version also evaluated the CVI for clarity. Results: After two evaluation rounds of the expert committee it was attained 98% agreement, attesting to the equivalence between the instrument versions, maximum values for representativeness I-CVI and S-CVI/Ave (1.00), and high values for clarity I-CVI (all items ≥0.97) and S-CVI/Ave (0.98). The expert committee members defined that the Brazilian version of the instrument would be called Índice Clínico Neonatal (NMI-Br). The NMI-Br reached high values of CVI for clarity (all I-CVI ≥0.86 and S-CVI/Ave=0.99) among the participants of the prefinal version. Conclusions: The NMI-Br is the Brazilian version of the NMI, obtained in a rigorous cross-cultural validation process, counting with adequate values of content validity.

Introduction: Necrotizing Enterocolitis is a disease that can affect the gastrointestinal tract of newborns, whose clinical manifestations can be characterized by bilious vomiting, blood in stool, abdominal distension, in addition to changes in hemodynamic parameters and thermal instability. The populations most vulnerable to this disease are low birth weight newborns exposed to the neonatal intensive care environment. Objectives: This study aimed to identify the profile of newborns and maternal and neonatal factors associated with the occurrence of deaths from necrotizing enterocolitis in a reference maternity hospital in Ceará, Brazil. Methodology: This is a retrospective cohort study seeking to describe the incidence ofa particular event over time, as well as establish causal relationships between the factors associated with the event. The study population comprised newborns who died from necrotizing enterocolitis between 2019 and 2021, who had neonatal death investigation forms filled out correctly, with no newborns being excluded, totaling a sample of 29 deaths. Results: It was identified that the profile of newborns was mostly premature, of low birth weight and with risk factors for other associated diseases such as sepsis, leading to invasive procedures and hospitalization in a neonatal intensive care environment. Conclusions: Prematurity and low birth weight were relevant variables in the study and may be associated with worsening of the newborn's clinical conditionsand development of necrotizing enterocolitis (AU).

Advances in epithelial mesenchymal transition signaling in bronchopulmonary dysplasia / 国际儿科学杂志

With the rapid development of perinatal medical technology, the survival rate of preterm infants has increased significantly, but the incidence of bronchopulmonary dysplasia(BPD)is still at a high level.BPD is a common chronic respiratory disease in preterm infants, and the incidence of other complications and death rates of preterm infants with BPD are significantly higher.Currently, the "classic BPD" characterized by lung injury has been converted to "new BPD, " but the pathophysiological mechanism of BPD has not yet been elucidated.In recent years, some experimental studies in vitro and in vivo have demonstrated that alveolar type II epithelial cells can induce epithelial mesenchymal transition(EMT)through multiple signaling pathways, including TGF-β as a hub and Wnt, SPHK1/S1P, etc., which can promote the development of pulmonary fibrosis, and thus provide a new idea for the prevention and treatment of BPD.This article reviews the mechanisms of multiple signaling pathways in EMT in BPD, in order to give a reference for the clinical treatment of BPD.

Risk factors of respiratory distress syndrome complicated by pulmonary hemorrhage in premature infants / 中国基层医药

Objective:To investigate the risk factors of respiratory distress syndrome (RDS) complicated by pulmonary hemorrhage (PH) in premature infants.Methods:A total of 102 infant patients with RDS whose gestational age was < 37 weeks received treatment in the Department of Neonatology, Kunming Children's Hospital (Children's Hospital Affiliated to Kunming Medical University) from January 2015 to July 2021 and were included in this study. According to the diagnostic criteria of PH, these infant patients were divided into a PH group and a non-PH group. The clinical data of the two groups were compared using a t-test, non-parametric test, or χ2 test. The risk factors of PH were analyzed. The independent risk factors of RDS complicated by PH in premature infants were determined using multivariate logistic regression analysis. Results:A total of 102 premature infants with RDS were collected, including 51 in the PH group and 51 in the non-PH group. The gestational ages at birth were (32.3 ± 3.0) weeks and (31.6 ± 3.0) weeks in the PH and non-PH groups, respectively. There were 36 males (70.6%) and 33 males (64.7%) in the PH and non-PH groups, respectively. There were no significant differences in proportion of males and gestational ages at birth between the two groups (both P > 0.05). The incidence of gestational age < 32 weeks [52.9% (27/51) vs. 31.3% (16/51)], PH and RDS complicated by patent ductus arteriosus [90.5% (38/42) vs. 70.0% (35/50)], and RDS grade 3-4 [80.4% (41/51) vs. 23.5% (12/51)] in the PH group were significantly higher than those in the non-PH group ( χ2 = 5.29, 4.66, 33.03, all P < 0.05). Multivariate logistic regression analysis showed that RDS grade 3-4 was an independent risk factor of RDS complicated by PH ( OR = 9.83, 95% CI: 3.545-27.265, P < 0.05). The proportion of infants with mechanical ventilation time ≥ 7 days in the PH group was significantly higher than that in the non-PH group [56.9% (29/51) vs. 31.4% (16/51), χ2 = 6.72, P < 0.05]. Conclusion:Gestational age < 32 weeks, PH and RDS complicated by patent ductus arteriosus, and RDS grade 3-4 are the risk factors of PH in premature infants with RDS. RDS grade 3-4 is an independent risk factor.

Restrição do crescimento intrauterino, prematuridade e baixo peso ao nascer: fenótipos de risco de morte neonatal, Estado do Rio de Janeiro, Brasil / Restricción del crecimiento intrauterino, prematuridad y bajo peso al nacer: fenotipos de riesgo de muerte neonatal, estado de Río de Janeiro, Brasil / Intrauterine growth restriction, prematurity, and low birth weight: risk phenotypes of neonatal death, Rio de Janeiro State, Brazil

Resumo: A restrição do crescimento intrauterino e a prematuridade determinam o baixo peso ao nascer, e a combinação das três condições resulta em diferentes fenótipos neonatais que interferem na sobrevivência infantil. Foram estimadas a prevalência, a sobrevivência e a mortalidade neonatal, segundo os fenótipos neonatais, na coorte de nascidos vivos de 2021 no Rio de Janeiro, Brasil. Foram excluídos nascidos vivos de gravidez múltipla, com anomalia congênita, e com inconsistências nas informações de peso e idade gestacional. Foi utilizada a curva Intergrowth para classificar adequação do peso, e estimadas a mortalidade (< 24 horas, 1-6 e 7-27 dias) e sobrevida (Kaplan-Meier). Dos 174.399 nascidos vivos, 6,8%, 5,5% e 9,5% eram, respectivamente, baixo peso ao nascer, pequeno para idade gestacional (PIG) e prematuros. Entre nascidos vivos com baixo peso ao nascer, 39,7% eram PIG e 70%, prematuros. Os fenótipos neonatais foram heterogêneos segundo características maternas, do parto, da gestação e do recém-nascido. A taxa de mortalidade por 1.000 nascidos vivos foi elevada para neonatos de baixo peso ao nascer prematuros, tanto PIG (78,1) quanto AIG (adequado para idade gestacional: 61,1), em todas as idades específicas. Houve reduções significantes da sobrevida quando comparados aos nascidos vivos não baixo peso ao nascer, AIG termo. As prevalências estimadas mostraram menores valores que as de outros estudos, em parte pelos critérios de exclusão adotados. Os fenótipos neonatais identificaram crianças mais vulneráveis e com maior risco de morte. A prematuridade contribuiu mais para a mortalidade que a condição de PIG; sua prevenção é necessária para reduzir a mortalidade neonatal no Estado do Rio de Janeiro.

Resumen: La restricción del crecimiento intrauterino y la prematuridad determinan el bajo peso al nacer, y la combinación de las tres condiciones da como resultado diferentes fenotipos neonatales que interfieren en la supervivencia infantil. Se estimó la prevalencia, supervivencia y mortalidad neonatal según los fenotipos neonatales, en la cohorte de nacidos vivos en 2021 en el Estado de Río de Janeiro, Brasil. Se excluyeron nacidos vivos de embarazo múltiple, con anomalía congénita y con inconsistencias en la información sobre el peso y edad gestacional. Se utilizó la curva Intergrowth para clasificar la adecuación de peso, y se estimó la mortalidad (< 24 horas, 1-6 y 7-27 días) y supervivencia (Kaplan-Meier). De los 174.399 nacidos vivos, 6,8%, 5,5% y 9,5% fueron, respectivamente, bajo peso al nacer, pequeños para la edad gestacional (PIG) y prematuros. Entre los bacidos vivos com bajo peso al nacer, el 39,7% eran PIG y el 70% prematuros. Los fenotipos neonatales fueron heterogéneos según las características maternas, del parto, del embarazo y del recién nacido. La tasa de mortalidad por 1.000 nacidos vivos fue alta para los neonatos bajo peso al nacer prematuros, tanto PIG (78,1) como AIG (apropiado para la edad gestacional: 61,1), en todas las edades específicas. Hubo reducciones significativas en la supervivencia en comparación con el término AIG bajo peso al nacer nos nacidos vivos. Las prevalencias estimadas mostraron valores inferiores a los de otros estudios, en parte debido a los criterios de exclusión adoptados. Los fenotipos neonatales identificó a los niños más vulnerables y con mayor riesgo de muerte. La prematuridad contribuyó más a la mortalidad que la condición PIG, y su prevención es necesaria para reducir la mortalidad neonatal en el Estado de Río de Janeiro.

Abstract: Intrauterine growth restriction and prematurity determine low birth weight. The combination of the three conditions results in different neonatal phenotypes that interfere with child survival. Neonatal prevalence, survival and mortality were estimated according to neonatal phenotypes in the cohort of live births in 2021 in the state of Rio de Janeiro, Brazil. In this study, live births of multiple pregnancies, with congenital anomalies and inconsistencies in the information of weight and gestational age were excluded. The Intergrowth curve was used to classify weight adequacy. Mortality (< 24 hours, 1-6 and 7-27 days) and survival (Kaplan-Meier) were estimated. In total, 6.8%, 5.5%, and 9.5% of the 174,399 live births were low birth weight, small for gestational age (SGA), and premature, respectively. Considering low birth weight live births, 39.7% were SGA and 70% were premature. The neonatal phenotypes were heterogeneous according to maternal, delivery, pregnancy, and newborn characteristics. The mortality rate per 1,000 live births was high for low birth weight premature newborns, both SGA (78.1) and AGA (adequate for gestational age: 61.1), at all specific ages. Reductions in the survival rate were observed when comparing non-low birth weight and AGA term live births. The estimated prevalence values were lower than those of other studies, partly due to the exclusion criteria adopted. The neonatal phenotypes identified children who were more vulnerable and at higher risk of death. Prematurity contributed more to mortality than SGA, and its prevention is necessary to reduce neonatal mortality in the state of Rio de Janeiro.

Effects of kinesiology taping on swallowing functions in newborns with swallowing difficulties: a randomized controlled pilot study

SUMMARY OBJECTIVE: This study investigated the efficacy of kinesiology taping application in premature infants with dysphagia. METHODS: A total of 60 premature newborns (born ≤37weeks' gestational age who reached the age ≥34 weeks of postmenstrual age) with sucking and swallowing problems were randomly assigned to the kinesiology taping group [n=31; 18 males, 13 females; mean postmenstrual age 35.4 weeks (SD 0.9 weeks, range 34-38 weeks)] or control group without kinesiology taping application [n=29; 16 males, 13 females; mean postmenstrual age age 35.6 weeks (SD 1.4 weeks, range 34-40 weeks)]. RESULTS: Kinesiology taping group yielded significant improvement in the oral reflexes (p<0.001) and in the sucking functions including tongue movement, sucking power, number of sucks and sucking pause, maintenance of alertness, jaw movement, tongue cupping, and maintenance of rhythm (p<0.001, p=0.011, p=0.002, and p=0.001, respectively). There was a significant difference in favor of the taping group with respect to the number of neonates whose feeding improved (26 (84%) vs. 7 (24%), p<0.001). CONCLUSION: The results of this study show that kinesiology taping can be applied as a safe and effective method to improve feeding functions in premature infants with sucking and swallowing difficulties.

Early death, morbidity and pharmacotherapy in extremely premature and very premature in neonatal intensive care units / Morte precoce, morbidade e farmacoterapia em prematuros extremos e muito prematuros em unidades de terapia intensiva neonatal

Abstract Objectives: to evaluate the evolution of extremely preterm and very preterm infants admitted to neonatal intensive care units, regarding the use of ventilatory support, morbidities, medication use, death, survival and viability. Methods: a non-concurrent cohort study, with 163 very premature and extreme newborns hospitalized in three neonatal intensive care units, during 2016 and 2017. A descriptive analysis of the data obtained from the medical records was performed. The outcomes studied were the use of ventilatory support, morbidities, medication use, death and causes of death. A survival curve was constructed and a viability limit was defined. Results: in the study, 28.2% were extreme and 71.8% were very premature. In this order of subgroups, the need for mechanical ventilation was higher for the extremes (65.2% and 41.0%) and the main diagnosis was early sepsis (78.6% and 82.6). Off-label (60.5% and 47.9%) and off-license (25.3% and 29.0%) medications were used. Most deaths (57.8%) occurred between the extremes, mainly due to septic shock. Survival was lower for the lowest gestational ages and the limit of viability was between 26 and 27 weeks. Conclusions: the main morbidities were from the respiratory system, with high use of off-label and unlicensed medications. Extremes had a greater demand for intensive care in addition to needing more drugs and progressing more to death.

Resumo Objetivos: avaliar a evolução dos prematuros extremos e muito prematuros internados em unidades de terapia intensiva neonatais, quanto ao uso de suporte ventilatório e de medicamentos, óbito, sobrevida e viabilidade. Métodos: estudo de coorte não concorrente, com 163 recém-nascidos muito prematuros e extremos internados em três unidades de terapia intensiva neonatais, durante 2016 e 2017. Realizou-se análise descritiva dos dados obtidos dos prontuários. Os desfechos estudados foram o uso de suporte ventilatório, morbidades, uso de medicamentos, óbito e causas de óbito. Foi construída curva de sobrevivência e delimitado um limite de viabilidade. Resultados: no estudo, 28,2% eram extremos e 71,8% muito prematuros. Nessa ordem de subgrupos, a necessidade de ventilação mecânica foi maior para os extremos (65,2% e 41,0%) e o principal diagnóstico foi sepse precoce (78,6% e 82,6).Medicamentos off-label (60,5% e 47,9%) e sem-licença (25,3% e 29,0%) foramutilizados. A maioria dos óbitos (57,8%) ocorreu entre os extremos, principalmente por choque séptico. A sobrevivência foi menor para as menores idades gestacionais e o limite de viabilidade ficou entre 26 e 27 semanas. Conclusões: as principais morbidades foram do sistema respiratório, com alto uso de medicamentos off-label e sem licença. Extremos tiveram maior demanda de cuidados intensivos além de necessitarem de mais medicamentos e evoluírem mais ao óbito.
