Heart rate variability in the evaluation of the autonomic nervous system of premature infants

One way to analyze the function of the autonomic nervous system (ANS) is through heart rate variability (HRV). This approach is based on the analysis of the distance between the peaks of two consecutive R waves expressed in electrocardiograms. HRV evaluations have been developed and have become more accessible and reliable through technological advances that enable the data collection in a simpler, non-invasive, and reliable way. However, there is little information in the scientific literature on the implementation of this methodology to assess the ANS of preterm infants. In this article, we survey the barriers, potential uses, and other topics regarding the assessment of the ANS in preterm infants using HRV.

Determinants of stillbirths occurred in health facilities in Zambezia province, Mozambique (2013-2014)

Abstract Objectives: to identify the determinants of stillbirths in Zambezia province, Mozambique. Methods: a retrospective cross-sectional ecological study was carried out in 2013-2014 by using perinatal indicators captured by the health information system in Zambezia. Sequentially perinatal care indicators, bivariate analysis and multiple adjusted regression at a 5% significance level with possible explainable variables of stillbirths were described. Results: a median proportion of stillbirths was 1.6%, low birth weight and preterm birth and obstetric complications were 4.9%, 1.9% and 4.1%, respectively. The bivariate analysis demonstrated association of stillbirths with anemia (p=0.043), antepartum hemorrhage (p=0.009), dystocic delivery (p<0.001), obstructed labor (p=0.004). In the analysis of multiple adjusted regression, the obstructed labor were a predictor (ß=0.435; p=0.03) to stillbirths Conclusions: the most important factor associated to stillbirths in health facilities in Zambezia province in 2013-2014 was the obstructed labor. The strengthening of diagnostic analysis and the attempt to handle obstetric complications is still a priority in Zambezia, in being able to decrease the avoidable perinatal deaths.

Relação entre as habilidades auditivas no primeiro ano de vida e o diagnóstico de linguagem em prematuros

RESUMO Objetivo: verificar se há relação entre as habilidades auditivas no primeiro ano de vida e o diagnóstico de linguagem entre os 2 e 4 anos de idade em crianças nascidas pré-termo com peso abaixo de 2000 gramas. Métodos: foram selecionados um grupo de 54 crianças com emissões otoacústicas evocadas por estímulos transientes presentes nos primeiros três meses, com avaliação audiológica comportamental entre os 6 e 18 meses e avaliação de linguagem entre os 2 e 4 anos de idade. Resultados: não foram observadas diferenças estatisticamente significantes entre a ocorrência de reflexo cócleo palpebral e a habilidade de localização sonora entre 6 e 18 meses com resultado da avaliação de linguagem.Em relação à habilidade de reconhecimento de ordens verbais entre os 12 e 18 meses foi observada diferença estatisticamente significante.Crianças que apresentam reconhecimento de ordens verbais alterado entre 12 e 18 meses tem 12,25 vezes mais chances de apresentar linguagem alterada entre os 2 e 4 anos. Conclusão: existe uma relação entre o reconhecimento de ordens verbais alterado entre 12 e 18 meses e a alteração no resultado da avaliação de linguagem entre os 2 e 4 anos.

[Development of premature children: caregivers' understanding according to the Bioecological Theory]

OBJECTIVE

Understanding the conceptions of premature children caregivers on child development and associated factors.

METHOD

An exploratory-descriptive qualitative study of 12 families with children under three years of age. Interviews were submitted to thematic content analysis, systematized into the categories of Bioecological Theory of Human Development: Process, Person, Context and Time, and in the Functional Development category.

RESULTS

There are concerns about impairment in the current and future development of a Person/child defined as fragile as a result of premature birth (Time dimension), minimized by the scope of observable competencies such as motor skills. The Context, especially family and health services, and Proximal Processes, described as one-way caregiver interactions, are considered determinants of development. Functional Development is considered a natural consequence and result of education. The support network is crucial, supporting or limiting care.

CONCLUSION

Concerns about the development mobilize caregivers to stimulate the premature child/person and requests family and healthcare assistance.
