ABSTRACT

BACKGROUND: The impact of ankyloglossia (tongue-tie) on breastfeeding outcomes may be overestimated and surgical treatment in newborns remains a controversial topic. The aim of the present study was to assess and quantify the impact of ankyloglossia in newborns on breastfeeding self-efficacy at 14 days of life. METHODS: A birth cohort study was conducted involving mothers and newborns soon after childbirth at a public hospital in the city of Canoas, southern Brazil. At the hospital, the lingual frenum of newborns were clinically examined and classified using the Bristol Tongue Assessment Tool. For every newborn with defined or suspected ankyloglossia, two newborns without ankyloglossia were co-enrolled for the study. At 14 days of the children's lives, the mothers were interviewed at home to collect data on breastfeeding self-efficacy using the Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). Poisson regression with robust variance was conducted to quantify differences in the Breastfeeding Self-Efficacy scores between exposed and nonexposed newborns after adjusting for maternal sociodemographic variables (mother's completed years of schooling, mother's age, family structure, progenitor status of child, mother's smoking status), the gestational variables (number of prenatal appointments, gestational age, comorbidities, type of childbirth), and child related variables (sex, birth weight, birth length) as confounders. RESULTS: The final sample was composed of 31 children with ankyloglossia (exposed) and 57 without ankyloglossia (nonexposed). No significant differences were found in the BSEF-SF scores between the 31 children with ankyloglossia (mean BSEF-SF scores: 56.0; median BSEF-SF scores: 60; 95% CI: 51.9-60.1) and the 57 children without ankyloglossia (mean BSEF-SF scores: 59.6; median BSEF-SF scores: 60; 95% CI: 57.5-61.7). The Poisson regression analysis showed no significant difference in the BSEF-SF scores between newborns with ankyloglossia and those without ankyloglossia (Ratio = 0.95; 95% CI: 0.88-1.02; p = 0.139). CONCLUSION: Ankyloglossia at birth exerted no clinically relevant impact on breastfeeding self-efficacy in children at 14 days of life.

ABSTRACT

OBJECTIVE: To identify the maternal characteristics associated with the diagnosis of fetal macrosomia at the Regional Hospital of Talca in the period between January 2017 and December 2023. MATERIALS AND METHODS: An observational, descriptive and analytical, retrospective study was carried out among the years 2017 and 2023. The population studied were pregnant women with a diagnosis of fetal macrosomia treated in the Prepartum service of the Regional Hospital of Talca, clinical variables of mothers and newborns were collected from the digital database of the Prepartum Unit of the Maule Hospital and Health System. The data were processed using the IBM SPSS Statistics v27 program. RESULTS: A total of 24,409 births were analyzed, among which 61 cases were excluded due to lack of maternal information and 48 cases due to lack of newborn data, leaving a total of 24,300 newborns for the analysis. Maternal age varies between 12 years and 58 years, average age 28.4 years. An association was found between fetal macrosomia and the factors: pregnancy in the process of prolongation and post-term, sex of the newborn and age of the mother at the time of delivery. CONCLUSIONS: The maternal characteristics associated with the diagnosis of fetal macrosomia are post-term delivery, gestational diabetes, excessive weight gain during pregnancy and sex of the newborn.

ABSTRACT

Objectives: To determine the prevalence of episiotomy over a 14-year period and to explore its association with maternal, delivery, and neonatal variables using administrative data. Material and methods: This is a cross-sectional study. Women who had a vaginal delivery with a live newborn at a referral hospital for obstetric care in Ecuador were included. Consecutive sampling was employed. ICD-10 records and the perinatal information system (PIS) were utilized. Sociodemographic, gestational, delivery, and neonatal variables were assessed. Descriptive analysis was performed. The overall and yearly prevalence was determined. Exploratory bivariate and multivariate analyses were conducted. The study was approved by the Human Research Ethics Committee of the Universidad Central del Ecuador. Results: A total of 11,862 records were analyzed. The overall prevalence of episiotomy was 36.69 %, with a maximum of 42 % and a minimum of 28 %. There is an implied trend towards a reduction in frequency from 2019 to 2022. A positive association was found between episiotomy and maternal age under 20 years, previous cesarean section, absence of a companion during delivery, term newborns, and large for gestational age newborns. A negative association was found with previous vaginal deliveries. Conclusions: The prevalence of episiotomy exceeds the recommendation of the World Health Organization (WHO). Clinical practice guidelines should consider potentially modifiable maternal and neonatal factors in their recommendations. Prospective studies should be conducted to evaluate the safety of the procedure, confirm these observations, and use robust methodologies to assess if there is a real decrease in its practice.


OBJETIVO: determinar la prevalencia de episiotomía en un periodo de tiempo de 14 años, y explorar su asociación con variables maternas, del parto y los resultados neonatales mediante la utilización de datos administrativos. Materiales y métodos: estudio transversal. Se incluyeron mujeres que tuvieron parto vaginal con recién nacido vivo, en una institución hospitalaria de referencia en atención obstétrica en Ecuador. Muestreo consecutivo. Se utilizaron los registros CIE-10 y del sistema informático perinatal (SIP), se evaluaron las variables sociodemográficas, de la gestación, el parto y neonatales. Análisis descriptivo. Se determinó la prevalencia global y por año. Se realizó análisis exploratorio bivariado y multivariado. Estudio aprobado por el Comité de Ética en Investigación en Seres Humanos de la Universidad Central del Ecuador. RESULTADOS: se analizaron 11.862 datos. La prevalencia global de episiotomía fue del 36,69%, con un máximo del 42 % y un mínimo del 28 %. Se insinúa una tendencia a la reducción de la frecuencia desde 2019 a 2022. Se encontró una asociación positiva entre su realización y la edad materna menor a 20 años, cesárea previa, ausencia de acompañante durante el parto, recién nacido a término, y grande para la edad gestacional. Se halló una asociación negativa con partos vaginales anteriores. CONCLUSIONES: la prevalencia de episiotomía supera la recomendación de la Organización Mundial de la Salud (OMS). Las guías de práctica clínica, en sus recomendaciones, deben considerar los factores maternos y neonatales asociados, potencialmente modificables. Se deberán realizar estudios prospectivos para evaluar la seguridad del procedimiento, confirmar estas observaciones y utilizar metodologías robustas para evaluar si hay una disminución real en su práctica.

ABSTRACT

OBJECTIVE: To analyze the experience of women aged 35 or over regarding the transition to unplanned motherhood. METHOD: A descriptive qualitative study, with semi-structured interviews with six women in this age group, selected by convenience, carried out in a high-risk prenatal clinic between July 2022 and July 2023. Analysis was based on Transitions Theory. RESULTS: Three main categories were identified: Transition properties (attributes of late motherhood); Transition conditions (personal, social and community factors as facilitators or inhibitors); and Response patterns (coping and adaptation strategies). The results highlight the emotional and psychosocial complexity, including the impact of social stigma, health challenges and the duality of old age, which brings both challenges and maturity. CONCLUSION: The need for public policies and specialized support to promote mental health, well-being and social integration is emphasized, aiming for a healthier and more empowered transition to motherhood.

ABSTRACT

OBJECTIVE: The objective of this study was to investigate factors influencing intrapartum fever in parturients receiving epidural labor analgesia. METHODS: This study included 410 parturients who received epidural labor analgesia at the authors' hospital between February 2022 and February 2024. Participants were divided into a fever group (>37.5℃) and a control group (<37.5℃) based on their body temperature post-analgesia. General data, gestational comorbidities, and intrapartum-related conditions were compared. Influencing factors were analyzed using the chi-squared test and logistic regression. RESULTS: Intrapartum fever occurred in 90 parturients (22.0%). Univariate analysis indicated that maternal age (p=0.046), parity (p=0.042), oxytocin use (p=0.041), and timing of analgesia (p<0.001) were associated with intrapartum fever. Multivariate analysis revealed that the timing of analgesia (OR 3.612, 95%CI 1.533-8.510) and amniotic fluid contamination degrees I (OR 1.072, 95%CI 1.012-3.082) and II (OR 2.874, 95%CI 1.901-9.092) were independent risk factors. No significant differences were found between the fever and control groups in body mass index, gestational age, gestational comorbidities, and artificial membrane rupture (p>0.05). Intrapartum fever increased the rate of neonatal fever within 2 h after birth (41.7 vs 18.6%, p<0.05) but did not significantly affect other neonatal health indicators. CONCLUSION: Timing of analgesia and amniotic fluid contamination are significant factors influencing intrapartum fever in parturients receiving epidural labor analgesia.

ABSTRACT

BACKGROUND: Living in high-altitude regions has been associated with a higher prevalence of some birth defects. Moderate altitudes (1500-2500 m) have been associated with some congenital heart diseases and low birth weight. However, no studies have been conducted for other isolated congenital malformations. OBJECTIVES: To estimate the prevalence at birth of isolated congenital malformations in low and moderate altitudes and to determine if moderate altitudes are a risk factor, such as high altitudes, for isolated congenital malformations adjusted for other factors. METHODS: The study consisted of a case-control multicenter-multiregional study of 13 isolated congenital malformations. Cases included live births with isolated congenital malformations and controls at low (10-1433 m) and moderate altitudes (1511-2426 m) from a Mexican registry from January 1978 to December 2019. Prevalence per 10,000 (95% CI) per altitude group was estimated. We performed unadjusted and adjusted logistic regression models (adjusted for maternal age, parity, malformed relatives, socioeconomic level, and maternal diabetes) for each isolated congenital malformation. RESULTS: Hydrocephaly and microtia had a higher at-birth prevalence, and spina bifida, preauricular tag, and gastroschisis showed a lower at-birth prevalence in moderate altitudes. Moderate altitudes were a risk factor for hydrocephaly (aOR 1.39), microtia (aOR 1.60), cleft-lip-palate (aOR 1.27), and polydactyly (aOR 1.32) and a protective effect for spina bifida (aOR 0.87) compared with low altitudes. CONCLUSIONS: Our findings provide evidence that moderate altitudes as higher altitudes are an associated risk or protective factor to some isolated congenital malformations, suggesting a possible gradient effect.

ABSTRACT

OBJECTIVES: To evaluate the association between perinatal and obstetric factors as potential triggers for the early onset of T1DM. METHODS: This was a retrospective cohort study enrolling 409 patients diagnosed with T1DM, in Bauru, São Paulo, Brazil, from 1981 to 2023. Data were retrieved from medical records, regarding sociodemographic parameters as age, sex, ethnicity, and socioeconomic status. Perinatal and obstetric factors as delivery type, gestational age, filiation order, length of exclusive breastfeeding, maternal age, maternal and fetal blood types, and occurrence of maternal gestational diabetes were also analyzed. An adapted survival analysis was employed to gauge the impact of each assessed variable at the age of T1DM diagnosis. RESULTS: The median age of T1DM diagnosis was 10.3 years with an interquartile range between 6.4 and 15.5 years. Delivery type and filiation order were the only factors statistically significantly associated with an early age at T1DM diagnosis. Patients who were born through cesarean section and who were firstborns showed a 28.6 and 18.0 % lower age at T1DM diagnosis, respectively, compared to those born through vaginal delivery and those that were nonfirstborns. CONCLUSIONS: Being born by cesarean section and being firstborn showed to be statistically significant factors to determine an early T1DM diagnosis.

ABSTRACT

PURPOSE: To assess the impact of maternal age on the association between maternal basal FSH and aneuploidy. METHODS: A retrospective study including data from 1749 blastocysts diagnosed as euploid or aneuploid by PGT-A (preimplantation genetic testing for aneuploidy). Aneuploidy incidence was compared between embryos from mothers with high vs. low basal FSH levels (above and below the group median, respectively) in total, pre-AMA (advanced maternal age; < 35 years, 198 embryos) and AMA (≥ 35 years, 1551 embryos) patient groups, separately. To control for the interference of potentially confounding variables, the association between aneuploidy and high basal FSH levels was assessed by multivariate logistic analysis in overall, pre-AMA and AMA patient groups. RESULTS: Overall, aneuploidy rate was 9% higher (p = 0.02) in embryos from patients with high basal FSH (63.7%) compared to those with low basal FSH (58.4%). In the pre-AMA subgroup, aneuploidy incidence was 35% higher (p = 0.04) in embryos from patients with high basal FSH (53.5%) compared to those with low basal FSH (39.4%). Differently, aneuploidy occurrence did not vary between embryos from AMA patients with low (61.0%) and high (64.8%) basal FSH (p = 0.12). The multivariate analysis revealed that, in pre-AMA embryos, the association between aneuploidy occurrence and high basal FSH is independent of potential confounding variables (p = 0.04). CONCLUSION: Maternal basal FSH values are associated with embryo aneuploidy in pre-AMA but not in AMA patients. The present findings suggest that basal FSH is a useful parameter to assess aneuploidy risk in pre-AMA patients and reinforce the hypothesis that excessive FSH signalling can predispose to oocyte meiotic errors.

ABSTRACT

AIM: To investigate iron-deficiency anemia as a risk factor for dental pulp disease in children from the central Peruvian jungle. METHODOLOGY: A case-control study was carried out with 270 children, of which 90 referred to cases and 180, to controls. Patients with pulp disease were diagnosed according to the criteria of the Association of Endodontists and the American Board of Endodontics. A specific questionnaire was used to assess ferrous sulfate consumption, maternal education level, maternal age, occupation, and household income. Data were analyzed using Pearson's correlation coefficient and a binary logistic regression. RESULTS: Iron deficiency anemia offers a risk factor for pulp disease in children (OR 7.44, IC 95% 4.0-13.8). According to multivariate analysis using binary logistic regression, ferrous sulfate consumption (OR 13.8, IC 95% 5.6.33.9), maternal education level (OR 2.4, IC 95% 1.1-5.3), maternal age (OR 7.5, IC 95% 2.9-19.4), household income (OR 4.0, IC 95% 1.6-9.6), and caries (OR 10.7, IC 95% 4.5-25.7) configured independent factors that were statistically associated with pulp disease. CONCLUSION: Iron deficiency anemia, ferrous sulfate consumption, maternal education level, maternal age, household income, and dental caries were positively associated with pulp disease in children.

ABSTRACT

BACKGROUND: Congenital Anomalies of the Upper Limb (CAUL) are a group of structural or functional abnormalities that develop during intrauterine life and can lead to limb dysfunction. OBJECTIVES: To analyze the prevalence of congenital anomalies of the upper limbs in Brazil and assess maternal and neonatal variables. DESIGN AND SETTING: A cross-sectional, descriptive study was conducted on congenital upper limb malformations among live births across Brazil. METHODS: The study spanned from 2010 to 2019. Data were sourced from the Department of Informatics of the Unified Health System (DATASUS) and the Live Birth Information System (SINASC) portal. Analyses focused on the information reported in field 41 of the Live Birth Declaration Form entered into the computerized system. RESULTS: The most common anomaly in Brazil was supernumerary fingers, classified as ICD-Q69.0, affecting 11,708 children, with a prevalence of 4.02 per 10,000 live births. Mothers aged over 40 years had a 36% higher prevalence of having children with CAUL than mothers under 40 years old (OR = 1.36; 95% CI 1.19-1.56). Newborns weighing ≥ 2,499 g were 2.64 times more likely to have CAUL compared to those weighing ≥ 2,500 g (OR = 2.64; 95% CI 2.55-2.73). CONCLUSION: There was an observed increase in the reporting of CAUL cases over the decade studied. This trend serves as an alert for health agencies, as understanding the prevalence of CAUL and its associated factors is crucial for preventive medicine.

ABSTRACT

Background: Given the pervasive issues of obesity and diabetes both in Puerto Rico and the broader United States, there is a compelling need to investigate the intricate interplay among BMI, pregestational, and gestational maternal diabetes, and their potential impact on the occurrence of congenital heart defects (CHD) during neonatal development. Methods: Using the comprehensive System of Vigilance and Surveillance of Congenital Defects in Puerto Rico, we conducted a focused analysis on neonates diagnosed with CHD between 2016 and 2020. Our assessment encompassed a range of variables, including maternal age, gestational age, BMI, pregestational diabetes, gestational diabetes, hypertension, history of abortion, and presence of preeclampsia. Results: A cohort of 673 patients was included in our study. The average maternal age was 26 years, within a range of 22 to 32 years. The mean gestational age measured 39 weeks, with a median span of 38 to 39 weeks. Of the 673 patients, 274 (41%) mothers gave birth to neonates diagnosed with CHD. Within this group, 22 cases were linked to pre-gestational diabetes, while 202 were not; 20 instances were associated with gestational diabetes, compared to 200 without; and 148 cases exhibited an overweight or obese BMI, whereas 126 displayed a normal BMI. Conclusion: We identified a statistically significant correlation between pre-gestational diabetes mellitus and the occurrence of CHD. However, our analysis did not show a statistically significant association between maternal BMI and the likelihood of CHD. These results may aid in developing effective strategies to prevent and manage CHD in neonates.

ABSTRACT

BACKGROUND: Preterm birth (PTB) is the main condition related to perinatal morbimortality worldwide. The aim of this study was to determine the indirect effects of neighbourhood socioeconomic status (NSES) on the risk of spontaneous PTB. METHODS: We carried out a retrospective case-control study including sociodemographic and obstetric data of multigravid women who gave birth at a maternity hospital in Tucumán, Argentina, between 2005 and 2010: 949 women without previous PTB nor pregnancy loss who delivered at term and 552 who had spontaneous PTB. NSES was estimated from the Unsatisfied Basic Needs index of census data. Variables selected through penalised regressions were used to create a data-driven Bayesian network; then, pathways were identified and mediation analyses performed. RESULTS: Maternal age less than 20 years mediated part of the protective effect of high NSES on spontaneous PTB [natural indirect effect (NIE) -0.0125, 95% confidence interval (CI) (-0.0208, -0.0041)] and on few prenatal visits (< 5) [NIE - 0.0095, 95% CI (-0.0166, -0.0025)]. These pathways showed greater sensitivity to unobserved confounders that affect the variables mediator-outcome in the same direction, and exposure-mediator in the opposite direction. They did not show sensitivity to observed potential confounders, nor to the parameterization used to define NSES. Meanwhile, urinary tract infections showed a trend in mediating the effect of low NSES on spontaneous PTB [NIE 0.0044, 95% CI (-0.0006, 0.0093), P 0.0834]. CONCLUSIONS: High NSES has protective indirect effects on spontaneous PTB risk, mainly associated with a lower frequency of teenage pregnancy.

ABSTRACT

OBJECTIVE: To describe temporal trends in the detection rates of gestational and congenital syphilis, by maternal age and health macro-region of the state of Paraná, Brazil, 2007-2021. METHODS: This was a time-series study using surveillance data; the trend analysis was performed by means of joinpoint regression, and average annual percent change (AAPC) and 95% confidence intervals (95%CI) were estimated. RESULTS: An increase in statewide detection of gestational syphilis (AAPC = 21.7; 95%CI 17.7; 32.8) and congenital syphilis (AAPC = 14.8; 95%CI 13.0; 19.7) was found; an increase was also found in the health macro-regions, with the Northwest (gestational, AAPC = 26.1; 95%CI 23.4; 31.6) and North (congenital, AAPC = 23.8; 95%CI 18.8; 48.9) macro-regions standing out; statewide rising trends were observed for young women [gestational, AAPC = 26.2 (95%CI 22.4; 40.6); congenital, AAPC = 19.4 (95%CI 17.6; 21.8)] and adult women [gestational, AAPC = 21.3 (95%CI 16.9; 31.9); congenital, AAPC = 13.7 (95%CI 11.9; 19.3)]. CONCLUSION: Maternal and child syphilis detection rates increased in the state, regardless of maternal age and health macro-region. MAIN RESULTS: Increasing trends were found for the detection rates of gestational and congenital syphilis in Paraná state and its health macro-regions, including in the analysis stratified by maternal age group; however, there was a decline during the COVID-19 period. IMPLICATIONS FOR SERVICES: There is a need for strategic and immediate action by the state health services, focusing on expanding access and linkage to care, in order to ensure maternal and child well-being and reverse the rising trends observed. PERSPECTIVES: Prevention and control actions towards the elimination of syphilis are needed to overcome these obstacles, directing efforts towards strengthening health education, early detection and appropriate treatment for pregnant women and their partners.

ABSTRACT

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)

Objetivo: Describir las características maternas y neonatales de los nacidos vivos en el Sistema de Información de Nacidos Vivos de Santa Catarina, Brasil. Materiales y métodos: Estudio transversal describiendo las características maternas y neonatales de 940.059 nacidos vivos entre 2010 y 2019. Se realizó la prueba de chi cuadrado de Pearson y exacta de Fisher y se estableció p < 0,05. Resultados: Los valores medios para la edad materna, el número de nacidos vivos y el número de mortinatos y abortos espontáneos fueron 27,1, 0,9 y 0,2, respectivamente. Las medias del número de semanas de gestación, el número de visitas prenatales, la fecha de inicio de la atención prenatal y el peso al nacer fueron 38,5 semanas (DE 2,2), 8,1 meses, 2,5 meses y 3 217,1 gramos, respectivamente. El bajo peso al nacer (BPN) fue prevalente entre las madres sin estudios (p < 0,001), incluidas las que no acudieron a una cita prenatal (p < 0,001). Hubo una mayor prevalencia de BPN en neonatos de sexo femenino (p < 0,001) con madres de edad ≥ 40 años (10,8%; p < 0,001). Los neonatos con buena vitalidad tuvieron una baja prevalencia de BPN (p < 0,001). La frecuencia de las variables estudiadas aumentó al comparar el inicio y el final del período y si las diferencias son estadísticamente significativas. Conclusiones: El estudio llama la atención sobre la necesidad de intervenciones para mejorar los indicadores que determinan el BPN(AU)

ABSTRACT

OBJECTIVE: This study aimed to evaluate the prevalence of hypertensive disorders during pregnancy among Brazilian women with preterm births and to compare the epidemiological characteristics and perinatal outcomes among preterm births of women with and without hypertension. METHODS: This was a secondary cross-sectional analysis of the Brazilian Multicenter Study on Preterm Birth. During the study period, all women with preterm births were included and further split into two groups according to the occurrence of any hypertensive disorder during pregnancy. Prevalence ratios were calculated for each variable. Maternal characteristics, prenatal care, and gestational and perinatal outcomes were compared between the two groups using χ2 and t-tests. RESULTS: A total of 4,150 women with preterm births were included, and 1,169 (28.2%) were identified as having hypertensive disorders. Advanced maternal age (prevalence ratio (PR) 2.49) and obesity (PR= 2.64) were more common in the hypertensive group. The gestational outcomes were worse in women with hypertension. Early preterm births were also more frequent in women with hypertension. CONCLUSION: Hypertensive disorders of pregnancy were frequent among women with preterm births, and provider-initiated preterm births were the leading causes of premature births in this group. The factors significantly associated with hypertensive disorders among women with preterm births were obesity, excessive weight gain, and higher maternal age.

ABSTRACT

BACKGROUND: Evaluating the ABO/RhD blood group and the direct antiglobulin Coombs test (DAT) at birth is recommended good practice, but there is variability in its universal implementation. This study aims to show the comparative results in various variables of clinical impact during the hospital stay of neonates with positive DAT compared with those with negative DAT, based on the systematic detection of the ABO/RhD group and DAT at birth. METHODS: Newborns between 2017 and 2020 in a high-risk pregnancy care hospital were included. The ABO/RhD and DAT group was determined in umbilical cord samples or the first 24 hours of life. Demographic, maternal, and neonatal variables were recorded. The association between the variables was estimated using the odds ratio (OR). RESULTS: 8721 pairs were included. The DAT was positive in 239 newborns (2.7%), with the variables associated with positive PDC being maternal age > 40 years (OR: 1.5; 95% CI: 1.0 to 2.3), birth by cesarean section (1.4; 1.1-2.0), mother group O (6.4; 3.8-11.8), prematurity (3.6; 2.6-5.0), birth weight < 2500 g (2.1; 1.6-2.8), newborn group A (15.7; 10.7-23.1) and group B (17.6; 11.4-27.2), hemoglobin at birth < 13.5 g/dl (4.5; 2.8-7.1) and reticulocytosis > 9% (1.9; 1.2 to 3.1). DISCUSSION: The frequency of neonatal positive PDC was 2.7%, with a significant association with maternal/neonatal incompatibility to the ABO and RhD group, with a substantial impact on various neonatal variables. These results support the policy of universal implementation at the birth of the ABO/RhD and DAT determination.


INTRODUCCIÓN: La determinación del grupo sanguíneo ABO/RhD y la prueba directa de Coombs (PDC) al nacimiento son una práctica recomendada, pero existe variabilidad en su implementación universal. Se presentan los resultados de la determinación al nacimiento del grupo ABO/RhD y la PDC en una cohorte institucional. MÉTODOS: Se incluyeron los recién nacidos entre 2017 y 2020 en un hospital de atención a embarazos de alto riesgo. Se determinó el grupo ABO/RhD y se realizó la PDC en muestras de cordón umbilical o en las primeras 24 horas de vida. Se registraron las variables demográficas, maternas y neonatales. Se estimó la asociación entre las variables mediante la razón de probabilidad (OR). RESULTADOS: Se incluyeron 8721 binomios. La PDC fue positiva en 239 recién nacidos (2.7%), siendo las variables asociadas a la PDC positiva la edad materna > 40 años (OR: 1.5;IC95%: 1.0-2.3), el nacimiento por vía cesárea (1.4; 1.1-2.0), la madre del grupo O (6.4; 3.8-11.8), la prematuridad (3.6; 2.6-5.0); el peso al nacer < 2500 g (2.1; 1.6-2.8); el neonato del grupo A (15.7; 10.7-23.1) o del grupo B (17.6; 11.4-27.2), la hemoglobina al nacer < 13.5 g/dl (4.5; 2.8-7.1) y la reticulocitosis > 9% (1.9; 1.2 a 3.1). DISCUSIÓN: La frecuencia de PDC positiva neonatal es del 2.7%, con asociación significativa la incompatibilidad materna/neonatal al grupo ABO y RhD, con impacto significativo en diversas variables neonatales. Estos resultados apoyan la política de implementación universal al nacimiento de la determinación de ABO/RhD y PDC.

ABSTRACT

Pregnancy, despite being a physiological process, can lead to morbidity and mortality, which is increased at risk ages, defined as younger or equal to15 years and older or equal to 35 years. For an adequate approach it is necessary to know the local reality of the population, therefore, the objective of this study is to describe and analyze the discharges of births and cesarean sections at risk age in the Maule Region from 2017 to 2021 using the database collected from the Biostatistics Unit of the Maule Health Service, which includes the hospitals of the region. Within the observed period, a total of 30,599 deliveries and cesarean sections were studied, being these a total of 5,581 at risk age, of which 0.65% corresponds to women younger or equal to 15 years and 17.57% to women older or equal to 35 years. There is a downward tendency in births in general, mostly evidenced in less or equal to 15 years, and on the contrary, a rise in births and cesarean sections of more or equal to 35 years, differing with the statistics at the country level. The tendency of increasing maternal age of pregnancies in the Maule region and its consequences are a fundamental factor when planning new public policies, so we consider it of vital importance to promote research and update the evidence, with a focus on the local population.


El embarazo a pesar de ser un proceso fisiológico puede conllevar morbimortalidad, la cual se acrecienta en edades de riesgo, definida como menor o igual a 15 años y mayor o igual a 35 años. Para el adecuado enfrentamiento se necesita conocer la realidad local, por ello, el objetivo de este estudio es describir y analizar los egresos de partos y cesáreas en edad de riesgo en la Región del Maule desde el año 2017 a 2021 utilizando la base de datos recogida desde la Unidad de Bioestadística del Servicio de Salud Maule, la cual incluye los hospitales de la región. Dentro del periodo observado se estudió un total de 30.599 partos y cesáreas, siendo estos un total de 5.581 en edad de riesgo, de los cuales 0.65% corresponde a mujeres menores o igual a 15 años y 17.57% a mujeres mayores o igual a 35 años. Existe una tendencia a la baja de los nacimientos en general, mayormente evidenciado en menores o igual a 15 años, y por el contrario, un alza en los partos y cesáreas de mayores o igual a 35 años, difiriendo con las estadísticas a nivel país. El aumento de la edad materna de los embarazos en la región del Maule y sus consecuencias son un factor fundamental a la hora de planificar nuevas políticas públicas, por lo que consideramos de vital importancia promover la realización de investigaciones y actualización de la evidencia sobre el tema, con un enfoque en la población local.

ABSTRACT

Breastfeeding (BF) is a human right, and it must start from birth. The adequacy of Rede Cegonha (RC) strategies can contribute to the promotion of BF. The objective was to identify factors associated with BF in the first and 24 hours of live births at full-term maternity hospitals linked to CR. Cross-sectional study with data from the second evaluation cycle 2016-2017 of the RC that covered all of Brazil. Odds ratios were obtained through binary logistic regression according to a hierarchical model, with 95% confidence intervals and p-value < 0.01. The prevalence of BF in the first hour was 31% and in the 24 hours 96.6%. The chances of BF in the first hour increased: presence of a companion during hospitalization, skin-to-skin contact, vaginal delivery, delivery assistance by a nurse and accreditation of the unit in the Baby-Friendly Hospital Initiative. Similar results at 24 hours, and association with maternal age below 20 years. BF in the first hour was less satisfactory than in the 24 hours, probably due to the high prevalence of cesarean sections, a factor associated with a lower chance of early BF. Continuous training of professionals about BF and the presence of an obstetric nurse during childbirth are recommended to expand BF in the first hour.


O aleitamento materno (AM) é um direito humano e deve ser iniciado desde o nascimento. A adequação das estratégias da Rede Cegonha (RC) pode contribuir na promoção do AM. O objetivo foi identificar os fatores associados ao AM na primeira e nas 24 horas de nascidos vivos a termo em maternidades vinculadas à RC. Estudo transversal com dados do segundo ciclo avaliativo 2016-2017 da RC, que abrangeu todo o Brasil. Foram obtidas razões de chance por meio de regressão logística binária segundo modelo hierarquizado, com intervalos de confiança a 95% e p-valor < 0,01. A prevalência de AM na primeira hora foi de 31%, e nas 24 horas, de 96,6%. Aumentaram as chances de AM na primeira hora: presença de acompanhante na internação, contato pele a pele, parto vaginal, assistência ao parto por enfermeira e acreditação da unidade na Iniciativa Hospital Amigo da Criança. Resultados semelhantes nas 24 horas, e associação com idade materna inferior a 20 anos. O AM na primeira hora foi menos satisfatório do que nas 24h, provavelmente pela elevada prevalência de cesariana, fator associado à menor chance de AM precoce. A capacitação dos profissionais sobre AM de forma contínua e a presença de enfermeiro obstetra no parto são recomendadas para ampliar o AM na primeira hora.

ABSTRACT

OBJECTIVE: The aim of this study was to analyze the outcomes of newborns with Down syndrome admitted to three neonatal intensive care units in the city of Rio de Janeiro, Brazil. METHODS: A retrospective cohort study was conducted by analyzing the medical records between 2014 and 2018 of newborns with Down syndrome admitted to three neonatal intensive care units. The following variables were analyzed: maternal and perinatal data, neonatal malformations, neonatal intensive care unit intercurrences, and outcomes. RESULTS: A total of 119 newborns with Down syndrome were recruited, and 112 were selected for analysis. The most common maternal age group was >35 years (72.07%), the most common type of delivery was cesarean section (83.93%), and the majority of cases were male (53.57%). The most common reasons for neonatal intensive care unit hospitalization were congenital heart disease (57.66%) and prematurity (23.21%). The most common form of feeding was a combination of human milk and formula (83.93%). The second most common malformation was duodenal atresia (9.82%). The most common complications during neonatal intensive care unit hospitalization were transient tachypnea of the newborn (63.39%), hypoglycemia (18.75%), pulmonary hypertension (7.14%), and sepsis (7.14%). The mean length of stay in the neonatal intensive care unit was 27 days. The most common outcome was discharge (82.14%). Furthermore, 12.50% of newborns were transferred to an external neonatal intensive care unit, and 6% died. CONCLUSION: Newborns with Down syndrome are more likely to be admitted to the neonatal intensive care unit, and the length of hospital stay is longer due to complications related to congenital malformations common to this syndrome and prematurity.

ABSTRACT

Resumo: A saúde sexual e reprodutiva é um pilar fundamental do sistema de saúde brasileiro, assinalando a importância das políticas públicas e programas voltados para a promoção dos direitos sexuais e reprodutivos. Nessas políticas, mulheres com 35 anos ou mais recebem pouca ou nenhuma atenção em relação a esse tema, pois as políticas estão voltadas para prevenção de doenças. Há uma crescente prevalência de gravidezes não planejadas nessa faixa etária e estudos não têm conseguido apreender conhecimentos acerca das experiências de mulheres que vivenciam a transição para a maternidade não planejada em idade avançada, a fim de aprimorar o cuidado a essas e promover uma transição bem-sucedida. Assim, o objetivo deste estudo foi desenvolver uma Teoria de Situação Específica para o cuidado de Enfermagem à mulher com 35 anos ou mais em transição para a maternidade de uma gestação não planejada, a partir da Teoria das Transições. O estudo caracteriza-se como teórico-exploratório de natureza qualitativa, que utilizou a Abordagem Integrativa para o desenvolvimento de Teorias de Situação Específica em enfermagem, guiada pela estratégia teoria-pesquisa-teoria, de Afaf Meleis. O processo metodológico envolveu um exercício reflexivo dedutivo, iniciando com a derivação dos conceitos centrais da Teoria das Transições. Seguiu-se a indução por meio de pesquisa de campo qualitativa, com entrevistas semiestruturadas de seis gestantes que não planejaram a gestação, com média de idade de 41 anos, ocorridas entre julho de 2022 a julho de 2023 no prénatal de alto risco de um hospital universitário do Sul do Brasil. Ainda indutivamente, produziuse dados a partir da reanálise de uma dissertação de Mestrado do grupo de pesquisa, bem como de revisão integrativa da literatura e da experiência com pesquisas prévias no tema, a fim de fundamentar o desenvolvimento da Teoria de Situação Específica. Foram desenvolvidas a partir disso declarações do metaparadigma, pressupostos e proposições. A teoria desenvolvida explica a transição para a maternidade não planejada em mulheres com 35 anos ou mais, contextualizando-a como um fenômeno social complexo, influenciado por fatores socioeconômicos, culturais, individuais e coletivos. A teoria explica como a maternidade tardia, especialmente quando não planejada, emerge como um papel em constante transformação, permeado por percepções diversas sobre o significado de ser mãe nessa fase da vida, desafiando frequentemente expectativas e crenças prévias. À medida que a experiência se amplia, concepções anteriores sobre a maternidade são questionadas, e novas são formadas, conduzindo a um processo de empoderamento e redefinição pessoal. Esta transição para a maternidade, marcada pela pluralidade de perspectivas e experiências, destaca a complexidade e a individualidade de cada mulher. Foi desenvolvida uma representação gráfica com as relações entre as declarações do metaparadigma., assim como nove proposições e cinco pressupostos. Esta teoria se baseia em vertentes do conhecimento científico atual para justificar sua construção, ressaltando a importância de compreender as experiências humanas e os contextos sociais onde ocorrem. A Teoria de Situação Específica atingiu o objetivo na medida em que propõe uma estrutura teórica em que o cuidado de enfermagem facilita os processos de transição e promove a interação entre cliente, ambiente, saúde e enfermagem. Além disso, possibilita que o enfermeiro provoque e estimule mudanças significativas nos resultados das transições por meio das terapêuticas de cuidado de enfermagem, evidenciando a necessidade de um cuidado personalizado e contextualizado, que leve em consideração a complexidade das experiências de maternidade tardia não planejada.


Abstract: Sexual and reproductive health is a fundamental pillar of the Brazilian healthcare system, highlighting the importance of public policies and programs aimed at promoting sexual and reproductive rights. In these policies, women aged 35 and older receive little or no attention regarding this issue, as the policies are focused on disease prevention. There is an increasing prevalence of unplanned pregnancies in this age group, and studies have not been able to capture knowledge about the experiences of women undergoing the transition to unplanned motherhood at an older age, in order to improve care for these women and promote a successful transition. Therefore, the aim of this study was to develop a Specific Situation Theory for nursing care of women aged 35 and older transitioning to motherhood from an unplanned pregnancy, based on the Transition Theory. The study is characterized as theoretical-exploratory with a qualitative nature, using the Integrative Approach for the development of Specific Situation Theories in nursing, guided by Afaf Meleis's theory-research-theory strategy. The methodological process involved a deductive reflective exercise, starting with the derivation of the central concepts of the Transition Theory. This was followed by induction through qualitative field research, with semi-structured interviews of six pregnant women who had unplanned pregnancies, with an average age of 41 years, conducted between July 2022 and July 2023 in the high-risk prenatal care of a university hospital in Southern Brazil. Inductively, data was also generated from the reanalysis of a master's thesis from the research group, as well as from an integrative literature review and experience with previous research on the topic, to support the development of the theory. From this, metaparadigm statements, assumptions, and propositions were developed. The developed theory explains the transition to unplanned motherhood in women aged 35 and over, contextualizing it as a complex social phenomenon, influenced by socioeconomic, cultural, individual, and collective factors. The theory elucidates how late motherhood, especially when unplanned, emerges as a role in constant transformation, permeated by diverse perceptions about the meaning of being a mother at this stage of life, often challenging previous expectations and beliefs. As the experience broadens, previous conceptions about motherhood are questioned, and new ones are formed, leading to a process of empowerment and personal redefinition. This transition to motherhood, marked by a plurality of perspectives and experiences, highlights the complexity and individuality of each woman. A graphic representation of the relationships between the metaparadigm statements was developed, along with nine propositions and five assumptions. This theory is based on strands of current scientific knowledge to justify its construction, emphasizing the importance of understanding human experiences and the social contexts in which they occur. The Specific Situation Theories achieved its objective insofar as it proposes a theoretical framework in which nursing care facilitates transition processes and promotes the interaction between client, environment, health, and nursing. Moreover, it enables the nurse to provoke and stimulate significant changes in transition outcomes through nursing care therapeutics, highlighting the need for personalized and contextualized care that considers the complexity of the experiences of unplanned late motherhood.
