Prevalência de nascimentos prematuros como desfechos de infecções pela COVID-19 na gestação / Prevalence of Preterm Birth as an Outcome of COVID-19 Infections during Pregnancy / Prevalencia de nacimientos prematuros producto de la infección por COVID-19 durante el embarazo

Objetivo: estimar a prevalência de nascimento prematuro em gestantes infectadas pela Covid-19, comparar índices de prematuridade entre infectadas e não infectadas e elucidar fatores associados à prematuridade. Métodos: coorte retrospectiva, com coleta de dados por inquérito online, de abril a dezembro de 2022, com mulheres que estiveram gestantes durante a pandemia, com acesso à internet, idade superior a 18 anos e que preencheram o primeiro inquérito online. Protocolo de pesquisa aprovado pelo Comitê de Ética. Resultados: primeiro inquérito respondido por 304 gestantes/puérperas, e o segundo por 82 (27%), compondo a amostra final. O índice de prematuridade no primeiro inquérito foi de 7,2% (n=14), já no segundo, 8,5% (n=7). A infecção pela Covid-19 não foi associada à prematuridade. A prematuridade associou-se a baixo peso, à necessidade de internação em centros de terapia intensiva neonatal e internações após o nascimento. Conclusão: a infecção pela Covid-19 não influenciou no aumento de nascimentos prematuros.

Objective: to estimate the prevalence of preterm birth in pregnant women infected with Covid-19, compare prematurity rates between infected and non-infected, and elucidate factors associated with prematurity. Methods: a retrospective cohort study was conducted using online survey data collected from April to December 2022, involving women who were pregnant during the pandemic, had internet access, were over 18 years old, and completed the initial online survey. The research protocol was approved by the Ethics Committee. Results: the initial survey was completed by 304 pregnant/postpartum women, and the follow-up survey by 82 (27%), comprising the final sample. The preterm birth rate in the initial survey was 7.2% (n=14), and in the follow-up survey, it was 8.5% (n=7). Covid-19 infection was not associated with prematurity. Prematurity was associated with low birth weight, the need for neonatal intensive care unit admission, and postnatal hospitalizations. Conclusion: Covid-19 infection did not influence an increase in preterm births.

Factors associated with early initiation of breastfeeding

Introduction: Early initiation of breastfeeding (EIBF) is still little stimulated in several hospitals in Brazil. Objective: To estimate the prevalence and factors associated with Early initiation of breastfeeding (EIBF). Methods: Cross-sectional, quantitative study with retrospective secondary data collection in hospital records of 250 full-term newborns, regardless of the type of delivery, with no history of maternal gestational risk, seen in the last six months. Data collection period in a public maternity hospital in Greater São Paulo. Data collection was performed between November 2018 and January 2019, with approval from the hospital and the FMABC Research Ethics Committee under register n. 2,924,393. Results: The prevalence of EIBF was 66%. BFH is associated with anesthesia at childbirth (p<0,001), APGAR less than or equal to 8 in the 1st and 5th minutes (p<0,001), and with c-section (p<0,001), which represented 29.2% of deliveries in the sample. Respiratory distress (38.82%), hypotonia (24.70%), followed by unfavorable maternal conditions (18.82%), were shown to be impeding factors for EIBF, although 90% of newborns received Apgar 9 /10 in the 5th minute. Conclusion: The prevalence of early breastfeeding is lower than recommended, but compatible with the most recent national frequency proportions.

Repensando o Nascimento como um Direito Integral na Luta contra a Violência Obstétrica no Brasil / Rethinking Birth as a Comprehensive Right in the Fight against Obstetric Violence in Brazil / Reconsiderando el Nacimiento como un Derecho Integral en la Lucha contra la Violencia Obstétrica en Brasil

Objetivo: analisar o impacto da ausência de legislação federal e normativas na mitigação da violência obstétrica no Brasil, por meio de uma análise crítica, com ênfase na regulação legal. Metodologia: inicialmente, realizou-se uma revisão narrativa de abordagem qualiquantitativa e exploratória-descritiva nas bases de dados da Biblioteca Virtual em Saúde e da Scientific Electronic Library Online, no período entre 2018 e 2023. Os artigos foram selecionados utilizando descritores do Medical Subject Headings, como "obstetric violence" e "violence against women", combinados através do operador booleano "AND". Posteriormente, foi conduzida uma pesquisa documental buscando consultar a legislação estadual vigente no Brasil e identificar possíveis lacunas. Resultados: Identificou-se uma lacuna considerável em relação à violência obstétrica e à conscientização limitada sobre os direitos à autonomia das mulheres, que são preocupações evidentes. Em relação às legislações estaduais analisadas, 14 fazem menção à "violência obstétrica" e 8 abordam a "humanização do parto". Dessas, 19 têm caráter informativo, 28 são preventivas e 2 são punitivas. Considerações Finais: A ausência de consenso na definição da violência obstétrica e a escassa capacitação dos profissionais de saúde resultam em práticas obsoletas. A elevada taxa de cesarianas desnecessárias e a carência de estudos sobre mulheres quilombolas e indígenas são preocupantes. No âmbito jurídico, a falta de compreensão por parte dos magistrados e a fragmentação das legislações estaduais representam desafios significativos. Torna-se crucial adotar uma abordagem multidisciplinar e políticas públicas claras para prevenir essa violência e assegurar uma assistência ao parto segura e centrada nas necessidades das mulheres.

Objective: To analyze the impact of the absence of federal legislation and regulations on the mitigation of obstetric violence in Brazil through a critical analysis, with emphasis on legal regulation. Methodology: Initially, a narrative review with a qualiquantitative and exploratory-descriptive approach was conducted on the databases of the Virtual Health Library and the Scientific Electronic Library Online, between 2018 and 2023. Articles were selected using Medical Subject Headings descriptors such as "obstetric violence" and "violence against women", combined with the boolean operator "AND". Subsequently, a documentary search was conducted to consult the current state legislation in Brazil and identify possible gaps. Results: A considerable gap was identified regarding obstetric violence and limited awareness of women's autonomy rights, which are evident concerns. Regarding the analyzed state laws, 14 mention "obstetric violence" and 8 address "humanization of childbirth". Of these, 19 are informative, 28 are preventive, and 2 are punitive. Final Considerations: The lack of consensus in defining obstetric violence and the scarce training of healthcare professionals result in obsolete practices. The high rate of unnecessary cesarean sections and the lack of studies on quilombola and indigenous women are concerning. In the legal sphere, the lack of understanding by judges and the fragmentation of state legislation represent significant challenges. It is crucial to adopt a multidisciplinary approach and clear public policies to prevent this violence and ensure safe and woman-centered childbirth care.

Introduction: Child health is conditioned by the circumstances of pregnancy, childbirth, and early life. Objective: To describe the maternal and neonatal characteristics of live births (LBs) in the Information System on Live Births of Santa Catarina (SC), Brazil. Materials and methods: A cross-sectional study describedthe maternal and neonatal characteristics of 940,059 LBs, from 2010 to 2019. Pearson's chi-square test and Fisher's exact test were conducted, with a statistical significance level of p < 0.05. Results: The mean values of maternal age, number of live children, and number of fetal deaths as well as abortions were 27.1 years, 0.9, and 0.2, respectively. The averages of the number of gestation weeks, number of prenatal consultations, the start date of the prenatal care, and birth weight were 38.5 weeks, 8.1 months, 2.5 monthsand 3,217.1 grams, respectively. Low birth weight (LBW) was prevalent among mothers without education (p < 0.001), including those without prenatal visits (p < 0.001). A higher prevalence of being underweight was observed among female neonates (p < 0.001) and with a maternal age of ≥ 40 years (10.8%; p < 0.001) compared to newborns with good vitality. Newborns with good vitality had a low prevalence of underweight (p < 0.001). The frequency of the variables studied increased, comparing the beginning and end of the period and whether the differences are statistically significant. Conclusions: The study draws attention to the need for interventions to improve the indicators that determine LBW(AU)

Peso al nacer en el noroeste argentino. Comparación con una referencia nacional y un estándar internacional / Birth weight in the Northwest region of Argentina. Comparison with a national reference and an international standard

Introducción. El tamaño al nacer se encuentra sujeto a influencias genéticas y ambientales; la altura geográfica es muy influyente. El peso al nacer (PN) es el indicador más utilizado para evaluarlo; existen diferentes estándares y referencias. Debido a la variabilidad de la distribución del PN en relación con la altura en la provincia de Jujuy (Argentina), este trabajo analiza la distribución percentilar del PN para tierras altas (TA) y tierras bajas (TB) jujeñas según edad gestacional (EG) y sexo, y su comparación con una referencia nacional y el estándar internacional INTERGROWTH-21st (IG-21). Población y métodos. Se analizaron los registros de 78 524 nacidos vivos en Jujuy en el período 20092014. Utilizando el método LMS, se estimaron los percentiles 3, 10, 50, 90 y 97 de PN/EG por sexo, para TA (≥2000 msnm), TB (<2000 msnm) y el total provincial, y se compararon gráficamente con la referencia poblacional argentina de Urquía y el estándar IG-21. La significación estadística se determinó mediante la prueba de Wilcoxon. Resultados. El PN en Jujuy presentó distribución heterogénea, con diferencias estadísticamente significativas (p <0,05) entre TB y TA. Al comparar con la referencia nacional y el estándar IG-21, se observaron diferencias por altitud, principalmente en los percentiles 90 y 97 para ambas regiones, y en los percentiles 3 y 10 en TA comparados con el estándar. Conclusiones. Se observó variabilidad de la distribución del PN asociada a la altura geográfica, por lo que, para evaluar el crecimiento intrauterino, resulta fundamental incluir la EG y el contexto donde transcurre la gestación.

Introduction. Size at birth is subject to genetic and environmental influences; altitude is highly influential. Birth weight (BW) is the most widely used indicator to assess size at birth; different standards and references are available. Due to the variability in BW distribution in relation to altitude in the province of Jujuy (Argentina), the purpose of this study is to analyze the percentile distribution of BW in the highlands (HL) and the lowlands (LL) of Jujuy based on gestational age (GA) and sex and compare it with a national reference and the INTERGROWTH-21 st (IG-21) international standard. Population and methods. The records of 78 524 live births in Jujuy in the 2009­2014 period were analyzed. Using the LMS method, the 3 rd, 10 th, 50 th, 90 th, and 97 th percentiles of BW/GA by sex were estimated for the HL (≥ 2000 MASL), the LL (< 2000 MASL), and the total for Jujuy, and compared with the Argentine population reference by Urquía and the IG-21 standard using growth charts. The statistical significance was established using the Wilcoxon test. Results. BW in Jujuy showed a heterogeneous distribution, with statistically significant differences (p < 0.05) between the LL and the HL. When compared with the national reference and the IG-21 standard, differences in terms of altitude were observed, mainly in the 90 th and 97 th percentiles for both regions and the 3 rd and 10 th percentiles in the HL compared with the international standard. Conclusions. BW distribution varied in association with altitude; therefore, to assess intrauterine growth, it is critical to include GA and the environment in which the pregnancy takes place.

Renal deficit and associated factors in children born with low birth weight / Déficit renal e fatores associados em crianças nascidas com baixo peso

ABSTRACT Introduction: Kidney problems may be due to low birth weight alone or may occur in association with other conditions. The objective this study was to evaluate the association between maternal and birth characteristics, anthropometric measurements, and kidney function deficit in low birth weight infants. Methods: Cross-sectional study with children who were born weighing < 2500 grams and were under outpatient follow-up. Maternal factors investigated were prenatal care and presence of hypertension, diabetes, and infection during pregnancy. The children's variables were sex, gestational age, birth weight, Apgar score, use of nephrotoxic medications, age, body weight at the time of evaluation, height, and serum creatinine and cystatin C dosages. The glomerular filtration rate (GFR) was estimated with the combined Zapittelli equation. Multivariate logistic regression model was used for identification of associated factors, with renal function deficit (GFR < 60 mL/min/1.73 m2) as the dependent variable. Results: Of the 154 children evaluated, 34.42% had kidney function deficit. Most of them had a gestational age > 32 weeks (56.6%), a mean birth weight of 1439.7 grams, and mean estimated GFR of 46.9 ± 9.3 mL/min/1.73 m2. There was a significant association of GFR < 60 mL/min/1.73 m2 with children's current weight and use of nephrotoxic drugs. Discussion: Children born with low birth weight had a high prevalence of kidney function deficit and current normal weight was a protective factor while the use of nephrotoxic drugs during perinatal period increased the chance of kidney deficit. These findings reinforce the need to evaluate the kidney function in these children, especially those who use nephrotoxic drugs.

RESUMO Introdução: Problemas renais podem ser devido apenas ao baixo peso ao nascer ou podem ocorrer em associação com outras condições. O objetivo deste estudo foi avaliar a associação entre características maternas e de nascimento, medidas antropométricas e déficit da função renal em bebês de baixo peso ao nascer. Métodos: Estudo transversal com crianças que nasceram com peso < 2500 gramas e estavam sob acompanhamento ambulatorial. Os fatores maternos investigados foram cuidados pré-natal e presença de hipertensão, diabetes e infecção durante a gravidez. As variáveis das crianças foram sexo, idade gestacional, peso ao nascer, índice Apgar, uso de medicamentos nefrotóxicos, idade, peso corporal no momento da avaliação, altura e dosagens séricas de creatinina e cistatina C. A taxa de filtração glomerular (TFG) foi estimada com a equação combinada de Zapittelli. Utilizou-se um modelo de regressão logística multivariada para identificação de fatores associados, com déficit da função renal (TFG < 60 mL/min/1,73 m2) como variável dependente. Resultados: Das 154 crianças avaliadas, 34,42% apresentaram déficit da função renal. A maioria tinha idade gestacional > 32 semanas (56,6%), peso médio ao nascer de 1439,7 gramas, e TFG média estimada de 46,9 ± 9,3 mL/min/1,73 m2. Houve uma associação significativa da TFG < 60 mL/min/1,73 m2 com o peso atual das crianças e o uso de medicamentos nefrotóxicos. Discussão: Crianças nascidas com baixo peso apresentaram alta prevalência de déficit da função renal e o peso atual normal foi um fator de proteção, enquanto o uso de medicamentos nefrotóxicos durante o período perinatal aumentou a chance de déficit renal. Estes achados reforçam a necessidade de avaliar a função renal destas crianças, especialmente aquelas que usam medicamentos nefrotóxicos.

Mortalidad infantil en la provincia de Santiago de Cuba durante el período 2008-2022

Introducción: La tasa de mortalidad infantil es un indicador importante y sensible del bienestar y la calidad de vida de una población, muy usado para medir su estado de salud. Objetivo: Caracterizar la mortalidad infantil según semestres en la provincia de Santiago de Cuba durante 2008-2022. Métodos: Se realizó un estudio observacional descriptico y transversal sobre la mortalidad infantil en la provincia de Santiago de Cuba durante los años 2008-2022. Para ello se analizó la relación existente entre los semestres de cada año respecto a los nacimientos, las defunciones y su incidencia en la tasa del país. Resultados: Se observó una disminución de los nacimientos y un incremento de las defunciones en cada quinquenio estudiado respecto al anterior. El número de fallecidos menores de un año fluctuó, con una tendencia al aumento a partir del 2019; asimismo, los indicadores de mortalidad infantil fueron inestables, con propensión al incremento, sobre todo en el segundo semestre, y peores resultados en el 2021 y 2022. Existió un descenso mantenido de los nacimientos a partir del 2011, que alcanzó 25,6 % en el 2022. Respecto a los semestres, en el segundo hubo mayor número de nacimientos, defunciones y tasas. Conclusiones: La provincia de Santiago de Cuba influye de forma directa en los resultados de la mortalidad infantil nacional, con una tasa superior a la exhibida por el país. El segundo semestre es el período en el que se incrementan los nacimientos y las defunciones, lo que incide en la elevación de las tasas respectivas.

Introduction: The infant mortality rate is an important and sensitive indicator of the well-being and life quality of a population, very used to measure the health state. Objective: To characterize the infant mortality in Santiago de Cuba province during the period 2008-2022. Methods: An observational descriptive and cross-sectional study about the infant mortality was carried out in Santiago de Cuba during the years 2008-2022. The existent relationship among the semesters of every year regarding births, deaths and their incidence in the country rate was analyzed. Results: A decrease of births and an increment of deaths were observed in each five year period studied regarding the previous one. The number of deceased children under one year fluctuated, with a tendency to the increase starting from 2019; also, the indicators of infant mortality were unstable, with tendency to the increment, mainly in the second semester, and worse results in 2021 and 2022. There was a maintained decrease of births since 2011 that reached 25.6% in 2022. In relation to semesters, in the second one there was a higher number of births, deaths and rates. Conclusions: Santiago de Cuba province influences in a direct way on the results of national infant mortality, with a superior rate to the one exhibited by the country. The second semester is the period in which births and deaths are increased, what impacts in the elevation of the respective rates.

Asociación del bajo peso al nacer con el control prenatal, la anemia materna y ser madre soltera

Fundamento: la elevada frecuencia de recién nacidos con peso inferior al adecuado, en relación con la anemia materna, la atención prenatal insuficiente y la condición de madre soltera, puede tener importantes repercusiones en la salud de las madres y los niños. Objetivo: identificar la relación entre el control prenatal, la anemia materna y la condición de ser madre soltera con el bajo peso al nacer de los infantes. Método: se realizó un estudio observacional, analítico y retrospectivo de casos y controles en gestantes atendidas en un hospital de la región Sierra de Ecuador durante el año 2022. La muestra fue de 280 pacientes. El grupo de casos lo conformaron las gestantes con hijos con bajo peso al nacer (n = 70) y el grupo de control por gestantes con recién nacidos con peso normal (n = 210). Se realizó la prueba de Chi cuadrado de independencia y se calculó el Odds Ratio y su intervalo de confianza del 95 % para el nivel de asociación entre las variables. Resultados: la relación de la variable asistencia a controles prenatales con respecto al bajo peso al nacer mostró una asociación protectora (OR = 0,5). Se identificaron como factores de riesgo, la anemia materna (OR = 3,1) y la condición de madre soltera (OR = 2,3) por sus altos valores de asociación positiva y directa. Conclusiones: el control prenatal, la anemia materna y la condición de madre soltera resultaron tener un nivel de asociación significativa con el bajo peso al nacer.

Foundation: the high frequency of newborns with less than adequate weight, in relation to maternal anemia, insufficient prenatal care and single mother status, can have important repercussions on the health of mothers and children. Objective: to identify the relationship between prenatal control, maternal anemia and the condition of being a single mother with low birth weight of infants. Method: an observational, analytical and retrospective case-control study was carried out in pregnant women treated in a hospital in the Sierra region of Ecuador during the year 2022. The sample was 280 patients. The case group was made up of pregnant women with children with low birth weight (n = 70) and the control group was made up of pregnant women with newborns with normal weight (n = 210). The Chi square test of independence was performed and the Odds Ratio and its 95 % confidence interval were calculated for the level of association between the variables. Results: the relationship between the variable attendance at prenatal check-ups and low birth weight showed a protective association (OR = 0,5). Maternal anemia (OR = 3,1) and being a single mother (OR = 2,3) were identified as risk factors due to their high values of positive and direct association. Conclusions: prenatal control, maternal anemia and single mother status turned out to have a significant level of association with low birth weight.

Anomalía de Ebstein: a propósito de un caso

La anomalía de Ebstein es una cardiopatía congénita rara y poco frecuente caracterizada por el adosamiento de los velos valvulares tricuspídeos; en la etapa prenatal se estima que su incidencia corresponde a un 3% de todas las cardiopatías diagnosticadas. Se presenta el caso de un feto con diagnóstico de anomalía de Ebstein a quien se le realizó un diagnóstico prenatal adecuado, lo que permitió planificar el nacimiento neonatal con un equipo multidisciplinario integral. Debido a la rareza del diagnóstico prenatal de esta entidad, se describe el caso clínico y los hallazgos imagenológicos representativos.

Ebsteins anomaly is a rare and infrequent congenital heart disease characterized by the attachment of the tricuspid valve leaflets; in the prenatal stage it is estimated that its incidence corresponds to 3% of all diagnosed heart diseases. We present the case of a fetus diagnosed with Ebsteins anomaly who underwent an adequate prenatal diagnosis, which made it possible to plan the neonatal birth with a comprehensive multidisciplinary team. Due to the rarity of the prenatal diagnosis of this entity, the clinical case and the representative imaging findings are described.

Prevalencia de osteopenia del prematuro antes y después de la implementación de una estrategia temprana de manejo fosfocálcico / Prevalence of osteopenia of prematurity before and after implementing an early strategy with the use of calcium and phosphate

Introducción. Con el uso de la nutrición parenteral agresiva en recién nacidos de muy bajo peso, se detectaron alteraciones del metabolismo fosfocálcico. En 2016 se implementó una estrategia de prevención a través del monitoreo fosfocálcico y su suplementación temprana. El objetivo fue estudiar si esta estrategia disminuye la prevalencia de osteopenia e identificar factores de riesgo asociados. Población y métodos. Estudio cuasiexperimental que comparó la prevalencia de osteopenia entre dos grupos: uno después de implementar la estrategia de monitoreo y suplementación fosfocálcica (01/01/2017-31/12/2019), y otro previo a dicha intervención (01/01/2013-31/12/2015). Resultados. Se incluyeron 226 pacientes: 133 pertenecen al período preintervención y 93 al posintervención. La prevalencia de osteopenia global fue del 26,1 % (IC95% 20,5-32,3) y disminuyó del 29,3 % (IC95% 21,7-37,8) en el período preintervención al 21,5 % (IC95% 13,6-31,2) en el posintervención, sin significancia estadística (p = 0,19). En el análisis multivariado, el puntaje NEOCOSUR de riesgo de muerte al nacer, recibir corticoides posnatales y el período de intervención se asociaron de manera independiente a osteopenia. Haber nacido luego de la intervención disminuyó un 71 % la probabilidad de presentar fosfatasa alcalina >500 UI/L independientemente de las restantes variables incluidas en el modelo. Conclusión. La monitorización y suplementación fosfocálcica precoz constituye un factor protector para el desarrollo de osteopenia en recién nacidos con muy bajo peso al nacer.

Introduction. With the use of aggressive parenteral nutrition in very low birth weight infants, alterations in calcium and phosphate metabolism were detected. In 2016, a prevention strategy was implemented through calcium phosphate monitoring and early supplementation. Our objective was to study whether this strategy reduces the prevalence of osteopenia and to identify associated risk factors. Population and methods. Quasi-experiment comparing the prevalence of osteopenia between two groups: one after implementing the calcium phosphate monitoring and supplementation strategy (01/01/2017­12/31/2019) and another prior to such intervention (01/01/2013­12/31/2015). Results. A total of 226 patients were included: 133 in the pre-intervention period and 93 in the post-intervention period. The overall prevalence of osteopenia was 26.1% (95% CI: 20.5­32.3) and it was reduced from 29.3% (95% CI: 21.7­37.8) in the pre-intervention period to 21.5% (95% CI: 13.6­31.2) in the post-intervention period, with no statistical significance (p = 0.19). In the multivariate analysis, the NEOCOSUR score for risk of death at birth, use of postnatal corticosteroids, and the intervention period were independently associated with osteopenia. Being born after the intervention reduced the probability of alkaline phosphatase > 500 IU/L by 71%, regardless of the other variables included in the model. Conclusion. Calcium phosphate monitoring and early supplementation is a protective factor against the development of osteopenia in very low birth weight infants.

Objective @#To investigate the fertility level of registered population in Baoshan District, Shanghai Municipality and the incidence of adverse birth outcomes of live births from 2013 to 2022, so as to provide the evidence for improving maternal and child health care strategies. @*Methods@#The data pertaining to live births registered in Baoshan District from 2013 to 2022 were collected through the Shanghai Birth Medical Information System, including the basic information of live births and maternal fertility. The indicators such as fertility level, parity, birth age and incidence of adverse birth outcomes of live births were descriptively analyzed. The trend of crude birth rate and total fertility rate was analyzed by annual percent change (APC). @*Results@#A total of 56 719 live births were registered in Baoshan District from 2013 to 2022. The crude birth rate was 6.54‰, the total fertility rate was 31.78‰, and the sex ratio at birth was 105.61. The crude birth rate showed a downward trend from 2016 to 2022 (APC=-11.054%, P<0.05), and the total fertility rate showed a downward trend from 2017 to 2022 (APC=-10.377%, P<0.05). The proportion of second parity and above showed an increasing trend from 2013 to 2017 (P<0.05) and a decreasing trend from 2017 to 2022 (P<0.05). The maternal childbearing age showed an increasing trend from 2013 to 2022 (P<0.05), the incidence of premature infants and low birth weight infants showed an increasing trend (both P<0.05). The incidence of premature infants and low birth weight infants increased with the rising childbearing age (both P<0.05). @*Conclusions@#The fertility level in Baoshan District was relatively low from 2013 to 2022. The proportion of second parity and above showed an upward trend followed by a downward trend. The incidence of premature infants and low birth weight infants increased with the rising childbearing age.

Low BMI is Associated with Poor OI-IUI Outcomes in Patients with Unexplained Primary Infertility / 中山大学学报(医学科学版)

ObjectiveTo evaluate the effect of women's body mass index （BMI） on pregnancy outcomes of ovulation induction intrauterine insemination （OI-IUI） in patients with unexplained primary infertility. MethodsThe study included 764 OI-IUI cycles from January 2016 to December 2022 in reproductive center of Sun Yat-sen Memorial Hospital. According to BMI，patients were divided into three groups：low BMI （BMI<18.5 kg/m2）， normal BMI （18.5 kg/m2 ≤BMI＜23.0 kg/m2）， and high BMI （BMI≥23.0 kg/m2）. Comparison of clinical data and pregnancy outcomes was performed between the groups. Logistic regression was used to analyze the association between BMI and live birth rate. ResultsFrom the low BMI group to the high BMI group， the HCG positive rate （7.08%，9.74%， 13.19%）， clinical pregnancy rate（5.51%， 7.91%， 13.19%）， and live birth rate （4.72%， 6.90%， 12.50%） increased. Among them， the live birth rate of the high BMI group was significantly higher than that of the low BMI group and the normal BMI group， with a statistically significant difference （P=0.034）. While the early miscarriage rate （14.28%， 10.26%， 5.26%） decreased from the low BMI group to the high BMI group. The binary logistic regression analysis revealed that BMI was an independent factor in live birth， and high BMI resulted in a better live birth rate than low BMI （OR=3.15，95%CI=1.191-8.329，P=0.021）. ConclusionLow BMI is associated with poor OI-IUI outcomes in patients with unexplained primary infertility. These patients are encouraged to gain weight in a healthy manner.

Maternal mid-upper arm circumference as a predictor of low birth weight outcome among newborn deliveries of adolescents in a Tertiary Level Hospital

Background@#Maternal malnutrition is a major cause of low birth weight (LBW) newborn outcome especially among adolescent mothers. It is one of the key drivers of child stunting and initiates the vicious cycle of intergenerational malnutrition. The body mass index prior to pregnancy or at the initial trimester is currently being used to establish the desired weight gain throughout pregnancy. However, Filipino adolescents often delay their first antenatal visit at a later stage of pregnancy. Without a baseline weight, the establishment of appropriate weight gain and nutritional status is often challenging. Mid-upper arm circumference (MUAC) was proven to be a good proxy measure of acute malnutrition, however, there was no global consensus on what MUAC cut-off point to use to identify pregnant adolescents at risk for delivering LBW babies. Finding the optimal cut-off could facilitate early identification and intervention of pregnant adolescents who are nutritionally at risk and could eventually break the cycle of intergenerational malnutrition.@*Objectives@#The study aims to determine the association of maternal MUAC and the birth weight outcomes among newborn deliveries of adolescents in a tertiary hospital for a period of six months and to identify the optimal maternal MUAC cut-off point that can be used to predict low birth weight outcome among newborn deliveries of adolescents in a tertiary hospital. Methods. A cross-sectional study was conducted among adolescents ages 10 to 19 years who delivered babies in a tertiary hospital in the Philippines for a period of six months. Maternal MUAC and LBW outcome were documented, and their association was determined using a logistic regression analysis. To measure diagnostic accuracy, the sensitivity, specificity, and the area under the curve were taken for each MUAC point. A receiver operating characteristic (ROC) curve was used to aid the MUAC cut-off determination.@*Results@#Out of 237 newborn deliveries, 35% were noted with low birth weight while 65% had normal birth weight. Most of the mothers were in their late adolescence at 78%. The crude association for the MUAC cut-offs ≤23.00 cm, ≤23.50 cm, and ≤24.00 cm and LBW showed a significant value of 2.19, 2.25, and 2.39 at 95% CI, respectively. However, it is only the cut-off ≤24.00 cm that showed significant results for adjusted association by the logistic regression analysis. The MUAC cut-off ≤24.00 cm also showed a better trade-off value between the sensitivity and specificity. Furthermore, the optimal maternal MUAC measurement that predicts LBW newborn outcome points to ≤24.00 cm cut-off based on the ROC curve.@*Conclusion@#This study shows that the maternal MUAC is predictive of LBW outcome among adolescent deliveries.A MUAC cut-off of ≤24.00 cm was superior to lower cut-offs studied. The pregnant adolescents might need a higher MUAC cut-off than adults to allow timely intervention and prevention of poor neonatal outcomes. By doing this simple screening test, suspected pregnant adolescents can be easily identified and referred for further confirmatory testing.

Overview of the establishment of Shanghai twin birth cohort / 上海预防医学

ObjectiveTo establish the Shanghai twin birth cohort （STBC） and analyze the effects of genetic factors， shared environment， and non-shared environment interactions on birth health and growth and development of newborns. MethodsBased on the population-wide birth cohort in Shanghai， a comprehensive survey was conducted on the families with double and multiple babies born after January 1， 2015 to collect information on birth health， growth and development， and the family environment of the babies. ResultsBy December 31， 2021， a total of 7 195 pairs （14 405 cases） of twins were successfully included in the STBC survey. The average birth length of twins was 47.2 cm and average birth weight was 2 465.3 g. Heterozygous twins accounted for 69.05% and preterm babies accounted for 57.07%. The average age of the mothers of twins was 31.82 years， and the average age of the fathers was 33.87 years， with more than 80% of the parents having a college degree or above. 44.50% of the mothers used assisted reproductive technologies， 7.40% had illnesses during pregnancy， and 15.90% were exposed to passive smoking during pregnancy. During the survey period， the average monthly increase in the length of the twin infants was 2.09 cm， and the average monthly weight gain was 0.53 kg. ConclusionThe incidence of adverse outcomes such as maternal cesarean section rate， preterm birth， and low birth weight is higher in the twin birth population. Information on birth health as well as growth and development in childhood and adolescence in the twin birth population is collected based on STBC， which can provide a solid data foundation for studying children’s chronic non-communicable diseases， psychological and behavioral disorders and other complex health problems caused by the combined effects of genetics and the environment.

Design and baseline characteristics of a population-based birth cohort in Shanghai / 上海预防医学

ObjectiveTo introduce the basic design， development plan and objectives of a population-based birth cohort in Shanghai， and further present the main data and baseline characteristics of enrolled participants in the cohort， and to provide key information for reproductive health-related studies. MethodsThe Shanghai population-based birth cohort initiated on January 1， 2005， included newborns born in Shanghai every year and their parents， and collected information on reproductive health， reproductive treatment， birth characteristics， growth and development status， as well as the incidence， treatment and death of diseases by employing data linkage technology and investigations. This formed a birth cohort spanning the entire life cycle. ResultsAs of October 2022， a total of 2 978 538 newborns and their parents were included in the cohort. Among them， 2 905 135 （97.54%） were naturally conceived （NC）， and 73 403 （2.46%） were born through assisted reproductive technologies （ART）. The average age of parents was （32.56±4.12） years old for females and （34.62±5.34） years old for males in the ART group， which was higher than （28.02±4.71） years and （30.07±5.54） years for parents in the NC group. Among parents， females and males aged 30 and above accounted for 77.12% and 85.08%， respectively， which were higher than that of parents （35.28% for females and 49.66% for males） in the NC group. Furthermore， the percentage of parents with a college degree or above in the ART group was 73.23% for females and 73.66% for males， which were higher than those in the NC group （49.98% and 50.91%， respectively）. The multiple births rate in the ART group was 33.81%， which was higher than that in the NC group （1.88%）. The incidence of premature birth and low birth weight in the ART group were 24.47% and 19.08%， respectively， which was higher than that in the NC group （5.47% and 3.73%）. ConclusionThe comprehensive collection of reproductive health-related information in the birth cohort in Shanghai can provide essential resources to determine the influence of genetics， environment， reproductive treatment and other related factors on the health of offspring after birth.

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.

Sociodemographic, behavioral, obstetric, and healthcare factors associated with low weight at birth: a case-control study

ABSTRACT BACKGROUND: Understanding social determinants is crucial for implementing preventive strategies, especially for low birth weight (LBW)—a public health issue that severely increases the risk of morbimortality in children. OBJECTIVE: This study aimed to identify the factors associated with LBW among newborns, assisted by the Brazilian Unified Health System. DESIGN AND SETTING: It analyzed data from newborns and their mothers. The sample was selected by convenience from users of the public health system in Francisco Beltrão (Paraná, Brazil). METHODS: Cases (n = 26) were babies weighing ≤ 2,500 g and controls (n = 52) > 2,500 g. All babies were assessed and paired by sex and date of birth in a 1:2 proportion. Statistical power was computed a posteriori, revealing a power of 87% (α = 0.05). RESULTS: Strong and significant differences were found in the bivariate analysis, in which the number of current smokers or those who quit during pregnancy was higher among mothers of babies with LBW. Moreover, the gestational weeks were lower among these cases. Logistic regression models indicated that the gestational week (odds ratio [OR] = 0.17, 95% confidence interval [CI]:0.05-0.54) and fathers' educational level (high school or above; OR = 0.22, 95% CI:0.06-0.99) were related to lower chances of low birth weight. CONCLUSIONS: Our findings confirm previous investigations on LBW's multi-causality, showing that the gestational week could reduce up to 82% chances of a baby being born with ≤ 2,500 g. Its association with paternal education underlines the importance of comprehensive policies to protect newborns.

A systematic review to investigate whether birth weight affects the autonomic nervous system in adulthood / Uma revisão sistemática para investigar se o peso ao nascer afeta o sistema nervoso autônomo na vida adulta

ABSTRACT Objective: To evaluate the relationship between birth weight and the autonomic nervous system in adulthood through a systematic review. Data source: This is a systematic review of publications without limitation of year and language. We included studies involving the autonomic nervous system and birth weight in adults. Manuscripts were selected based on electronic searches of Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science Cochrane Library and Scopus databases, using "Autonomic Nervous System" OR "Heart Rate" OR "Heart Rate Variability" AND "Birth Weight" as a search strategy. This review is registered on the International Prospective Register of Systematic Reviews — PROSPERO (ID: CRD42020165622). Data synthesis: We found 894 articles; 215 were excluded for duplicity. Of the remaining 679 studies, 11 remained. Two were excluded because they did not specifically treat the autonomic nervous system or birth weight. There were nine publications, two cohort and seven cross-sectional studies. The main findings were that extreme, very low, low or high birth weight may have some impact on the autonomic nervous system in adult life. Conclusions: Birth weight outside the normality rate may have a negative influence on the autonomic nervous system, causing autonomic dysfunction and increasing the risk of cardiovascular diseases in adult life. Thus, the importance of the follow-up of health professionals from pregnancy to gestation and throughout life, with preventive care being emphasized.

RESUMO Objetivo: Avaliar a relação entre o peso ao nascer e o sistema nervoso autônomo na vida adulta por meio de uma revisão sistemática. Fontes de dados: Esta é uma revisão sistemática de publicações, sem limitação de ano e idioma. Incluímos estudos envolvendo o sistema nervoso autônomo e peso ao nascer em adultos. Os manuscritos foram selecionados das bases de dados eletrônicos Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science Cochrane Library e Scopus, utilizando "Autonomic Nervous System" OR "Heart Rate" OR "Heart Rate Variability" AND "Birth Weight" como estratégia de busca. Esta revisão está registrada pelo International Prospective Register of Systematic Reviews — PROSPERO (ID: CRD42020165622). Síntese dos dados: Nós encontramos 894 artigos. Deles, 215 foram excluídos por duplicidade. Entre os 679 remanescentes, 11 permaneceram, dos quais dois foram excluídos por não tratarem especificamente do sistema nervoso autônomo ou do peso ao nascer. Restaram nove publicações, sendo duas longitudinais e sete transversais. Os principais achados foram que o peso extremo baixo, muito baixo, baixo ou alto ao nascer pode ter algum impacto no sistema nervoso autônomo na vida adulta. Conclusões: O peso ao nascer fora da normalidade pode influenciar negativamente o sistema nervoso autônomo, causando disfunção autonômica e aumentando o risco de doenças cardiovasculares na vida adulta. Assim, ressalta-se a importância do acompanhamento dos profissionais de saúde desde a gravidez até a gestação, pré-natal e ao longo da vida, com cuidados preventivos para esta situação.
