An investigation of the umbilical artery N-terminal proBrain natriuretic peptide levels of fetuses due to fetal distress in term pregnancies.

OBJECTIVE: This study aimed to investigate umbilical artery N-terminal proBrain natriuretic peptide (NT-proBNP) in fetuses delivered by cesarean section due to fetal distress in term pregnancies. METHODS: This prospective case-control study was conducted at the Antalya Training and Research Hospital Obstetric Department, Turkiye. A total of 140 pregnant women, 70 underwent elective cesarean sections between weeks 37 and 40 of gestation (Group 1, the control group) and 70 underwent cesarean sections due to fetal distress (Group 2, the study group), were included. The participants' sociodemographic and obstetric data and fetal umbilical blood NT-proBNP levels were recorded in a database. RESULTS: Age, body mass index, gestational age, prenatal diagnostic tests, fetal anatomical scanning, and baby gender ratios were comparable between the groups (p>0.05), while statistically significant differences were observed in terms of gravidity (3.0 vs. 1.0, p≤0.001) and parity numbers (2 vs. 0, p≤0.001), baby height (50.36±0.88 vs. 49.80±0.86, p≤0.001) and weight (3422.43±409.16 vs. 3239.86±293.74, p=0.003), 1-min Apgar (9.0±0.1 vs. 8.5±1.3, p≤0.001) and 5-min Apgar (10.0±0.1 vs. 9.8±0.4, p=0.026) scores, umbilical artery pH (7.32±0.05 vs. 7.25±0.07, p≤0.001), umbilical artery base deficit (-2.48±1.23 vs. -4.36±1.09. p≤0.001), and NT-proBNP levels [8.77 (7.72-9.39) vs. 12.35 (9.69-12.92), p<0.001]. CONCLUSION: This study showed that NT-proBNP can be used as an important marker in the diagnosis of fetal distress. Prospective studies with more participants are now needed to confirm the accuracy of our results.

Anquilobléfaro filiforme congênito / Ankyloblepharon filiforme adnatum

RESUMO O anquiloblefáro filiforme congênito é uma rara anomalia congênita, caracterizada por uma fusão palpebral, parcial ou completa, cuja incidência é de 4,4 por 100 mil recém-nascidos. Normalmente, o anquiloblefáro filiforme congênito constitui uma malformação solitária, de ocorrência esporádica, no entanto, pode estar associado a outras malformações. O pediatra possui papel imprescindível para observar as alterações clínicas do recém-nascido e dar orientação para o tratamento adequado. O objetivo deste estudo foi relatar o caso de recém-nascido de termo que teve diagnóstico precoce de anquiloblefáro filiforme congênito associado a outras malformações congênitas, tendo desfeito as aderências em procedimento cirúrgico oportuno, evitando-se a evolução para futuras complicações visuais do paciente.

ABSTRACT Ankyloblepharon filiforme adnatum is a rare congenital anomaly, characterized by partial or complete palpebral fusion, with an incidence of 4.4 per 100,000 newborns. Normally, ankyloblepharon filiforme adnatum constitutes a solitary malformation, with sporadic occurrence, however, it can be associated with other malformations. Pediatricians play an essential role in observing clinical changes in newborns and providing guidance on appropriate treatment. The this study aims to report the case of a full-term newborn who had an early diagnosis of ankyloblepharon filiforme adnatum associated with other congenital malformations.

Intended delivery mode and neonatal outcomes in pregnancies with fetal growth restriction.

Objective: To compare neonatal outcomes in pregnancies with fetal growth restriction (FGR) by intended delivery mode.Methods: This is a retrospective cohort study of singleton pregnancies with FGR that were delivered ≥34.0 weeks gestation. Neonatal outcomes were compared according to the intended delivery mode, which the attending obstetrician determined. Of note, none of the subjects had a contraindication to labor. Crude and adjusted odds ratios (ORs) and corresponding confidence intervals (CIs) were calculated via logistic regression models to assess the potential association between intended delivery mode and neonatal morbidity defined as a composite outcome (i.e. umbilical artery pH ≤7.1, 5-min Apgar score ≤7, admission to the neonatal intensive care unit, hypoglycemia, intrapartum fetal distress requiring expedited delivery, and perinatal death). A sensitivity analysis excluded intrapartum fetal distress requiring emergency cesarean delivery from the composite outcome since only patients with spontaneous labor or labor induction could meet this criterion. Potential confounders in the adjusted effects models included maternal age, body mass index, hypertensive disorders, diabetes, FGR type (i.e. early or late), and oligohydramnios.Results: Seventy-two (34%) patients had an elective cesarean delivery, 73 (34%) had spontaneous labor and were expected to deliver vaginally, and 67 (32%) underwent labor induction. The composite outcome was observed in 65.3%, 89%, and 88.1% of the groups mentioned above, respectively (p < 0.001). Among patients with spontaneous labor and those scheduled for labor induction, 63% and 47.8% required an emergency cesarean delivery for intrapartum fetal distress. Compared to elective cesarean delivery, spontaneous labor (OR 4.32 [95% CI 1.79, 10.42], p = 0.001; aOR 4.85 [95% CI 1.85, 12.66], p = 0.001), and labor induction (OR 3.92 [95% CI 1.62, 9.49] p = 0.002; aOR 5.29 [95% CI 2.01, 13.87], p = 0.001) had higher odds of adverse neonatal outcomes.Conclusion: In this cohort of FGR, delivering at ≥34 weeks of gestation, pregnancies with spontaneous labor, and those that underwent labor induction had higher odds of neonatal morbidity than elective cesarean delivery.

Lactate and pH values in newborns with a history of acute fetal distress.

BACKGROUND: Acute fetal distress (AFD) is a condition that requires timely diagnosis because it generates hypoxia, acidosis, and even intrauterine death. This study aimed to determine lactate and pH values in the umbilical cord in full-term newborns (NBs) with a history of AFD. METHODS: We conducted a cross-sectional study in full-term NBs of mothers with at least one perinatal, neonatal, or gasometric AFD antecedent. Neonatal morbidity was considered: if 1-min Apgar ≤ 6, or advanced neonatal maneuvers, or neonatal intensive care unit (NICU) admissions were necessary. The cutoff points were lactate > 4mmol/L and pH < 7.2. RESULTS: Of 66 NBs, 33.3% of mothers presented at least one antecedent for developing AFD; 22.7% presented hypertensive pregnancy disease, 13.6% oligohydramnios, and 63.6% other factors. Perinatally, 28.7% required advanced neonatal resuscitation maneuvers and 7.5% admission to the NICU. In the gasometry, the lactate and pH values for the neonatal morbidity of the NBs' group were 4.726 ± 1.401 and 7.293 ± 0.056, respectively, versus 2.240 ± 0.318 and 7.359 ± 0.022 (p < 0.05) for the group without associated neonatal morbidity. CONCLUSIONS: Lactate values in the umbilical cord increased by 25%, and pH decreased by one percent in NBs with a history of AFD and associated morbidity.

INTRODUCCIÓN: El sufrimiento fetal agudo (SFA) es una condición que amerita un diagnóstico oportuno debido a que genera hipoxia, acidosis e incluso la muerte intrauterina. El objetivo de este estudio fue determinar los valores de lactato y pH en cordón umbilical en recién nacidos de término con antecedente SFA. MÉTODOS: Se llevó a cabo un estudio transversal, en recién nacidos a término, de madres que tuvieron al menos un antecedente para SFA de tipo perinatal, neonatal o gasométrico. Se consideró morbilidad neonatal cuando presentaron Apgar al minuto ≤ 6, o requirieron maniobras avanzadas de reanimación neonatal, o ingreso a Unidad de Cuidados Intensivos Neonatales (UCIN). El punto de corte fue > 4 mmol/L para los valores de lactato y pH < 7.2. RESULTADOS: De un total de 66 recién nacidos, el 33.3% de las madres presentaron al menos un antecedente para desarrollar SFA; el 22.7% presentó enfermedad hipertensiva del embarazo, el 13.6%, oligohidramnios, y el 63.6%, otros factores. El 28.7% requirieron maniobras avanzadas de la reanimación neonatal y el 7.5%, el ingreso a la UCIN. En la gasometría, el valor de lactato y pH para el grupo de recién nacidos con morbilidad neonatal fue de 4.726 ± 1.401 y 7.293 ± 0.056 respectivamente, versus 2.240 ± 0.318 y 7.359 ± 0.022 (p < 0.05) para el grupo sin morbilidad neonatal asociada. CONCLUSIONES: Se observó un incremento del 25% de los valores de lactato en cordón umbilical y una disminución del 1% del pH en los recién nacidos con antecedente de SFA y morbilidad asociada.

Saúde mental e abortamento voluntário na audiência pública da ADPF442/STF / Mental health and voluntary abortion in the public hearing of ADPF442/STF / Salud mental y aborto voluntario en la audiencia pública del ADPF442/STF

O estudo teve como objetivo identificar os argumentos da estratégia de persuasão dos discursos apresentados na audiência pública sobre a Arguição de Descumprimento de Preceito Fundamental-ADPF 442, realizada em 2018, cujo propósito era discutir sobre a interrupção voluntária da gravidez até a 12ª semana. Para tal, foi realizada uma pesquisa de abordagem qualitativa, analítico-descritiva e documental. O objeto de análise foi o registro da audiência, apresentado em vídeo, disponibilizado na plataforma digital YouTube, e em ata lavrada pelo STF, ambos de acesso público. A partir de uma análise do discurso, identificou-se os argumentos utilizados na estratégia de persuasão, que foram sistematizados em quatro categorias de argumentos para cada um dos dois grupos identificados: o grupo pró e o grupo contra a descriminalização do aborto. As três primeiras categorias, Saúde mental, Direito e Saúde pública, mesmo com diferenças na forma de apresentar o argumento, se repetem nos dois grupos. Todavia, a quarta categoria, Pressupostos, se diferenciou. No grupo pró descriminalização do aborto, apresentou-se como Pressupostos filosóficos e científicos, e no grupo contra, como Pressupostos morais. Por fim, a defesa da saúde mental das mulheres foi o principal argumento numa forma de humanizar o sofrimento vivido pelas que desejam abortar e não encontram o suporte do Estado para assegurar sua dignidade, cidadania e efetiva igualdade, garantidas constitucionalmente.(AU)

The study aimed to identify the arguments of the persuasion strategy of the speeches presented at the public hearing on the Action Against the Violation of Constitutional Fundamental Rights -ADPF 442, held in 2018, whose purpose was to discuss the voluntary interruption of pregnancy until the 12th week. To this end, a qualitative, analytical-descriptive, and documentary research was carried out. The object of analysis was the video recording of the hearing available on the YouTube platform, and in minutes drawn up by the STF, both of which are public. Based on a discourse analysis, the arguments used in the persuasion strategy were identified, which were systematized into four categories of arguments for each of the two identified groups: the group for and the group against the decriminalization of abortion. The first three categories, Mental Health, Law and Public Health, even with differences in the way of presenting the argument, are repeated in both groups. However, the fourth category, Assumptions, differed. In the group for the decriminalization of abortion, it was presented as Philosophical and Scientific Assumptions, whereas the group against, as Moral Assumptions. Finally, the defense of women's mental health was the main argument in a way of humanizing the suffering experienced by those who wish to have an abortion and do not find the support of the State to guarantee their dignity, citizenship, and effective equality, constitutionally guaranteed.(AU)

El estudio tuvo como objetivo identificar los argumentos de la estrategia de persuasión de los discursos presentados en la audiencia pública sobre el Argumento por Incumplimiento de un Percepto Fundamental -ADPF 442, realizada en 2018, con el objetivo de discutir la interrupción voluntaria del embarazo hasta la 12.ª semana. Para ello, se llevó a cabo una investigación cualitativa, analítico-descriptiva y documental. El objeto de análisis fue la grabación de la audiencia, que está disponible en la plataforma digital YouTube, y actas levantadas por el Supremo Tribunal Federal -STF, ambas de acceso público. A partir de un análisis del discurso se identificaron los argumentos utilizados en la estrategia de persuasión, los cuales se sistematizaron en cuatro categorías de argumentos para cada uno de los dos grupos identificados: el grupo pro y el grupo en contra de la despenalización del aborto. Las tres primeras categorías ("salud mental", "derecho" y "salud pública") aún con diferencias en la forma de presentar el argumento se repiten en ambos grupos. Pero difiere la cuarta categoría "supuestos". En el grupo a favor de la despenalización del aborto se presentó como "supuestos filosóficos y científicos", y en el grupo en contra, como "supuestos morales". Finalmente, la defensa de la salud mental de las mujeres fue el principal argumento en un intento por humanizar el sufrimiento que viven aquellas que desean abortar y no encuentran el apoyo del Estado para garantizar su dignidad, ciudadanía e igualdad efectiva, preconizadas por la Constitución.(AU)

Escore de Apgar e indicação de cesárea por sofrimento fetal em um hospital público do Distrito Federal / Apgar score and indication of cesarean section due to fetal distress at a public hospital in the Federal District

Objetivo: Avaliar as indicações de cesárea por sofrimento fetal (SF), pelo escore de Apgar, em um hospital público. Métodos: Estudo de corte transversal e retrospectivo que incluiu todos os partos realizados no período de estudo. A análise estatística foi realizada no software IBM SPSS Statistics v.22 com teste do qui-quadrado de Pearson para o cálculo do p-valor. A estimativa de risco foi definida pela razão de chances comum de Mantel-Haenszel, com cálculo de odds ratio (OR), intervalo de confiança de 95% (IC95%) e limite de significância de 95% (p < 0,05). Resultados: Dos 2.205 partos, 1.084 (49,1%) foram cesáreas e 1.121 (50,9%), partos vaginais. Escore de Apgar < 7 no primeiro minuto foi evidenciado em 5,9% do total de partos. A diferença entre os escores de Apgar no primeiro minuto entre os dois tipos de parto foi estatisticamente significante (p < 0,05), e esses recém-nascidos (RNs) tiveram a chance 1,4 vez maior de Apgar < 7 nas cesáreas em relação ao parto vaginal (OR: 1,4; IC95%: 1-2,05). No quinto minuto, Apgar < 7 ocorreu em 0,7% em todos os tipos de partos. O SF foi a terceira causa de indicação de cesárea (22,8%), e o Apgar < 7 não diferenciou das cesáreas por demais causas. Conclusão: Este estudo demonstrou alta taxa de cesárea e maior risco de Apgar < 7 no primeiro minuto para esses partos. A ausência de diferença estatisticamente significante entre o Apgar dos RNs de cesárea por SF e demais indicações revela a necessidade local de rever esse diagnóstico e consequente conduta.(AU)

Objective: To evaluate the cesarean indications for fetal distress (FD), using the Apgar score, in a public hospital. Methods: Cross-sectional and retrospective study, which included all the deliveries performed during the period of study. Statistical Analysis was performed using the IBM SPSS Statistics v.22 software with Pearson's Chi-square test to calculate the p-value. The risk estimate for Apgar < 7 was defined by the common odds ratio (OR) of Mantel-Haenszel, with calculation of OR and 95% confidence interval and significance limit of 95% (p < 0.05). Results: Of the 2,205 deliveries, 1,084 (49.1%) were cesarean and 1,121 (50.9%) were vaginal deliveries. Apgar score < 7 in the 1st minute was seen in 5.9% of total deliveries. The difference between the Apgar Scores in the 1st minute between the two types of delivery was statistically significant (p < 0.05), and these newborns (NBs) had 1.4 times more chance of Apgar < 7 in cesarean in relation to vaginal delivery (OR: 1,4; IC95%: 1-2,05). In the 5th minute, Apgar < 7 occurred in 0.7% of all types of births. FD was the third cause of cesarean indication (22.8%) and the Apgar < 7 wasn't different from the cesareans performed for other causes. Conclusion: This study demonstrated a high cesarean rate and a bigger risk of Apgar < 7 in the 1st minute for this type of delivery. The absence of statistically significant difference between the Apgar of NBs of cesarean due to FD and other indications reveal the need to review this diagnosis e it's conduct.(AU)

Fetal distress during the last third of pregnancy in bitches - evaluation by Doppler ultrasound imaging

Background: Diagnostic ultrasound has revolutionized obstetric practice. Doppler techniques provided in vivo studies of the fetus-placental and uterus-placental circulations, in an increasingly precise manner. The assessment of fetal well-being is essential in obstetric practice, however, in veterinary medicine, there is a deficit of ultrasound parameters related to fetal distress. The main of this research was to determine the hemodynamic characteristics and behavior, through Doppler ultrasonography, of maternal-fetal vessels during the final third of gestation in bitches with fetuses under stress, as well as correlating them with each other and with fetal distress. Materials, Methods & Results: An observational, prospective study was carried out, in which 30 healthy bitches were examined, during the last third of pregnancy, with fetuses under fetal distress. Fetuses were evaluated in 2 stages: (1st): 50-54 days and (2nd): 55-60 days of gestation. All fetuses were calmly assessed, one by one, and fetal heart rate (FHR) was measured 5 times, for at least 3 min, to identify and confirm fetal distress. At least 3 fetuses were evaluated in each bitch and each measurement was performed in triplicate, setting a hemodynamic mean for each value evaluated. The flow pattern in the middle cerebral artery (MCA), internal carotid artery (ICA) and umbilical artery (UA) was evaluated. The analyzed vessel was initially visualized in B mode, followed by evaluation by color and spectral Doppler. The variables observed were: peak systolic velocity (PSV), end diastolic velocity (EDV) and the resistivity (RI) and pulsatility (PI) index, as well as the systole/diastole ratio (S/D). The analysis of RI and PI of the umbilical artery showed a statistically significant difference between the mean values found for the times studied, increasing from time 1 to time 2. For middle cerebral and internal carotid arteries, PI, RI and the relationship systole/diastole (S/D), showed a statistically significant difference between the mean values found for the times studied, decreasing from time 1 to time 2. Discussion: Fetal heart rate (HR) findings are considered normal above 200 beats per minute (bpm), only if preceded by acceleration and deceleration. This fact confirms the presence of fetal stress, by this parameter, for the fetuses in the present study. Corroborating the picture of fetal distress, another study concluded that HR tends to increase up to 20 days before delivery, a fact that did not occur in the study in question, where animals in the same gestational period were evaluated. Recent research has concluded that an elevated umbilical artery PI at 28 weeks of gestation, in the absence of fetal growth restriction or prematurity, is associated with some adverse cognitive findings in 12-year-olds children. In the present study, a progressive increase in this index was observed throughout the final third of pregnancy. Although the pups were not monitored after birth, this data serves as a warning for veterinarians, and can be useful in the assessment and diagnosis of possible postnatal nervous alterations. Like what was found in the present study, a study reported that from the 4th week to birth, the PSV of the umbilical artery (UA) increased almost linearly, with high significance. For the middle cerebral arteries, the PI showed a statistically significant difference between the mean values found for the times studied, however, decreasing throughout the final third of pregnancy.

Resilience and Stress during Pregnancy: A Comprehensive Multidimensional Approach in Maternal and Perinatal Health.

This narrative review addresses resilience and stress during pregnancy, which is part of a broader concept of maternal health. Pregnancy and postpartum are opportune periods for health promotion interventions, especially because the close contact of the women with health professionals. In this way, it can be considered a useful window of opportunity to identify women at higher risk for adverse outcomes. Integrated health is a concept that aims at providing comprehensive care related to the promotion of individuals' physical, mental, and social well-being. In this context, stress during pregnancy has been targeted as a remarkable condition to be addressed whether due to individual issues, social issues, or specific pregnancy issues, since it is directly and indirectly associated with pregnancy complications. Stress is associated with preterm birth, postpartum depression, anxiety, child neurodevelopment, and fetal distress. The way that an individual faces a stressful and adverse situation is called resilience; this reaction is individual, dynamic, and contextual, and it can affect maternal and fetal outcomes. Low resilience has been associated with poorer pregnancy outcomes. The social context of pregnancy can act as a protective or contributory (risk) factor, indicating that environments of high social vulnerability play a negative role in resilience and, consequently, in perceived stress. A given stressor can be enhanced or mitigated depending on the social context that was imposed, as well as it can be interpreted as different degrees of perceived stress and faced with a higher or lower degree of resilience. Understanding these complex mechanisms may be valuable for tackling this matter. Therefore, in the pregnancy-puerperal period, the analysis of the stress-resilience relationship is essential, especially in contexts of greater social vulnerability, and is a health-promoting factor for both the mother and baby.

Risk Factors for Intrapartum Cesarean Section Delivery in Low-risk Multiparous Women Following at Least a Prior Vaginal Birth (Robson Classification 3 and 4).

OBJECTIVE: The aim of the present study was to evaluate the risk factors for cesarean section (C-section) in low-risk multiparous women with a history of vaginal birth. METHODS: The present retrospective study included low-risk multiparous women with a history of vaginal birth who gave birth at between 37 and 42 gestational weeks. The subjects were divided into 2 groups according to the mode of delivery, as C-section Group and vaginal delivery Group. Risk factors for C-section such as demographic characteristics, ultrasonographic measurements, smoking, weight gain during pregnancy (WGDP), interval time between prior birth, history of macrosomic birth, and cervical dilatation at the admission to the hospital were obtained from the charts of the patients. Obstetric and neonatal outcomes were compared between groups. RESULTS: The most common C-section indications were fetal distress and macrosomia (33.9% [n = 77 and 20.7% [n = 47] respectively). A bivariate correlation analysis demonstrated that mothers aged > 30 years old (odds ratio [OR]: 2.09; 95% confidence interval [CI]: 1.30-3.34; p = 0.002), parity >1 (OR: 1.81; 95%CI: 1.18-2.71; p = 0.006), fetal abdominal circumference (FAC) measurement > 360 mm (OR: 34.20; 95%CI: 8.04-145.56; p < 0.001)) and < 345 mm (OR: 3.06; 95%CI: 1.88-5; p < 0.001), presence of large for gestational age (LGA) fetus (OR: 5.09; 95%CI: 1.35-19.21; p = 0.016), premature rupture of membranes (PROM) (OR: 1.52; 95%CI: 1-2.33; p = 0.041), and cervical dilatation < 5cm at admission (OR: 2.12; 95%CI: 1.34-3.34; p = 0.001) were associated with the group requiring a C-section. CONCLUSION: This is the first study evaluating the risk factors for C-section in low-risk multiparous women with a history of vaginal birth according to the Robson classification 3 and 4. Fetal distress and suspected fetal macrosomia constituted most of the C-section indications.

Reporte de caso: ruptura uterina durante trabajo de parto, en útero sin cicatriz previa / Case review: uterine rupture during labor, in uterus without previous scar

Resumen La ruptura uterina es una complicación obstétrica poco frecuente con una alta morbilidad y mortalidad materna e infantil. El diagnóstico precoz y el tratamiento inmediato son factores pronósticos importantes tanto para la madre como para el feto. Se presenta el caso de una paciente multigestante, con alto riesgo por diabetes gestacional compensada y déficit de proteína S sin manejo, con embarazo a término y adecuado control prenatal, que ingresa hemodinámicamente estable, con cambios cervicales iniciales, feto en presentación longitudinal, cefálico con monitoreo fetal categoría ACOG 1 para conducción del trabajo de parto, y presenta ruptura uterina espontánea, dando lugar a un hemoperitoneo materno y sufrimiento fetal agudo con posterior tratamiento quirúrgico de urgencia mediante una cesárea e histerectomía, por atonía uterina sin control del sangrado con maniobras farmacológicas. Este caso es muy significativo por la falta de factores de riesgo y su presentación clínica atípica, tanto en síntomas y signos como en la ubicación de la ruptura. MÉD. UIS.2021;34(1): 107-12.

Abstract Uterine rupture is a rare obstetric complication with high maternal and infant morbidity and mortality. Early diagnosis and immediate treatment are important prognostic factors for both mother and fetus. The study presents the case of a multigravida patient, with high risk for compensated gestational diabetes, and uncontrolled protein S deficiency. The patient, who was full-term and had adequate prenatal control, was admitted hemodynamically stable, with initial cervical changes, fetus in longitudinal presentation, andcephalic with monitoring category ACOG 1. The patient spontaneous uterine rupture, which leads to maternal hemoperitoneum and acute fetal distress. Cesarean section and hysterectomy were performed as emergency surgical treatments due to uterine atony without bleeding control with pharmacological maneuvers. This case is great significance due to the lack of risk factors and the atypical clinical presentation, evidenced in the signs and symptoms and the rupture's location. MÉD.UIS.2021;34(1): 107-12.

Chikungunya infection in pregnancy - reassuring maternal and perinatal outcomes: a retrospective observational study.

OBJECTIVE: To evaluate pregnancy and neonatal outcomes, disease severity, and mother-to-child transmission of pregnant women with Chikungunya infection (CHIKV). DESIGN: Retrospective observational study. SETTING: Grenada. POPULATION: Women who gave birth during a Chikungunya outbreak between January 2014 and September 2015 were eligible. METHODS: This descriptive study investigated 731 mother-infant pairs who gave birth during a CHIKV outbreak. Women and infants underwent serological testing for CHIKV by ELISA. MAIN OUTCOME MEASURES: Primary outcomes: composite pregnancy complication (abruption, vaginal bleeding, preterm labour/cervical incompetence, cesarean delivery for fetal distress/abruption/placental abnormality or delivery for fetal distress) and composite neonatal morbidity. RESULTS: Of 416 mother-infant pairs, 150 (36%) had CHIKV during pregnancy, 135 (33%) had never had CHIKV, and 131 (31%) had CHIKV outside of pregnancy. Mean duration of joint pain was shorter among women infected during pregnancy (µ = 898 days, σ = 277 days) compared with infections outside of pregnancy (µ = 1064 days, σ = 244 days) (P < 0.0001). Rates of pregnancy complications (RR = 0.76, P = 0.599), intrapartum complications (RR = 1.50, P = 0.633), and neonatal outcomes were otherwise similar. Possible mother-to-child transmission occurred in two (1.3%) mother-infant pairs and two of eight intrapartum infections (25%). CONCLUSION: CHIKV infection during pregnancy may be protective against long-term joint pain sequelae that are often associated with acute CHIKV infection. Infection during pregnancy did not appear to pose a risk for pregnancy complications or neonatal health, but maternal infection just prior to delivery might have increased risk of mother-to-child transmission of CHIKV. TWEETABLE ABSTRACT: Chikungunya infection did not increase risk of pregnancy complications or adverse neonatal outcomes, unless infection was just prior to delivery.

Impact of SARS-CoV-2 (COVID-19) on pregnancy: a systematic review and meta-analysis protocol.

INTRODUCTION: The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has been growing at an accelerating rate, and has become a public health emergency. Pregnant women and their fetuses are susceptible to viral infection, and outcomes in this population need to be investigated. METHODS AND ANALYSIS: PubMed, Web of Science, Embase, CINAHAL, Latin American and Caribbean Health Sciences Literature, clinicaltrials.gov, SCOPUS, Google Scholar and Cochrane Central Controlled Trials Registry will be searched for observational studies (cohort and control cases) published from December 2019 to present. This systematic review and meta-analysis will include studies of pregnant women at any gestational stage diagnosed with COVID-19. The primary outcomes will be maternal and foetal morbidity and mortality. Three independent reviewers will select the studies and extract data from the original publications. The risk of bias will be assessed using the Newcastle-Ottawa Scale for observational studies. To evaluate the strength of evidence from the included data, we will use Grading of Recommendation Assessment, Development, and Evaluation method. Data synthesis will be performed using Review Manager software V.5.2.3. To assess heterogeneity, we will compute the I2 statistics.

Factores de riesgo que inciden en la mortalidad neonatal en el Hospital Dr. León Becerra Camacho Del Cantón Milagro 2014-2017 / Risk factors that affect neonatal mortality in the Dr. León Becerra Hospital Camacho Del Cantón Milagro 2014-2017

Según la OMS, la mortalidad neonatal está asociada a factores que son de necesaria identificación para reducir la incidencia. El objetivo del trabajo es identificar los factores de riesgo que inciden en el evento. Se utilizó un diseño transversal, retrospectivo, descriptivo, cuantitativo, con una población de 74 neonatos que fallecieron en los servicios de neonatología del Hospital Dr. León Becerra Camacho 2014-2017. Los resultados arrojan que de los neonatos fallecidos, el mayor porcentaje es el sexo masculino, de madres con edades entre 21 y 35 años, donde la mayoría pertenecen a zonas urbanas con instrucción secundaria incompleta y dedicada a las labores del hogar. Como características maternas encontramos que la mayoría, fueron secundigestas, el 60.81% con controles mínimos, el 56,7% con parto vaginal. Las características Obstétricos encontradas revelan que el 67.5% tuvieron menos de 1-2 años de periodo intergenésico, el 100% presentaron Infecciones de vías Urinarias, 44.5% tuvieron Ruptura Prematura de Membrana, y desproporción cefálica con traumas obstétricas en un 33,7%. Como factores neonatales y fetales tenemos que el 51.3% fueron neonatos a Término con peso adecuado para edad gestacional, y el 51.3% tuvieron depresión severa y 44,5% con sufrimiento fetal, siendo la patología más frecuente la Asfixia en un 51,3% seguido del 33,7% de Membrana Hialina, y las comorbilidades más comunes son la acidosis metabólica en un 87.8%, seguidos de 48.6% con prematurez. Se propone fortalecer los protocolos para el manejo de la embarazada, que permitan mejorar la calidad de la atención, favoreciendo al binomio madre hijo(AU)

According to OMS, neonatal mortality is associated with factors that are necessary to identify the incidence. The objective of the work is to identify the risk factors that affect the event.

A historical, systematic review of handedness origins.

Handedness ontogenesis is still under debate in science. This systematic review analyzed articles regarding the theories and basis of handedness formation, highlighting the historical knowledge path that this literature underwent. Cochrane Library, LILACS, Web of Sciences, Science Direct and PubMed databases were searched. This review included review studies with handedness as the main topic. Only papers written in English with analyses exclusively in neurotypical humans (any age range) were included. Different approaches (genetic, neural, social, and behavioural) were reviewed in light of growing evidence, summarizing the current state of the art. Genetic and environmental/social impacts are common points in most of the reviews, each given more or less importance, depending on the author and theory proposed. Multifactorial, developmental approaches to handedness formation seem to be the most up to date view of the phenomenon. Different control mechanisms between hemisphere and neural asymmetries are also contributing factors to handedness formation.

Association between non-invasive nursing care technologies during childbirth and neonatal vitality: a cross-sectional study / Asociación entre tecnologías no-invasivas de cuidado en el parto y la vitalidad neonatal: estudio transversal / Associação entre tecnologias não invasivas de cuidado no parto e vitalidade do recém-nascido: estudo transversal

Abstract Objective: to compare the use of non-invasive midwifery care technologies (TNICEO) with the use of traditional care model practices, having as parameters the presence of meconium in the amniotic fluid and its repercussion on the newborn's vitality. Method: a cross-sectional study with secondary data of 10,219 parturients who delivered by midwives between September 2004 and October 2016. Logistic regression was used to assess Apgar> 8 Odds Ratio in exposure to noninvasive midwifery care technologies when compared to traditional care. Results: there were higher percentages of light amniotic fluid and neonates with good vitality in parturients who used only TNICEO compared with those exposed only to traditional care. Conclusion: nurse midwives' provision of TNICEO and its use by women are efficient strategies to reduce unfavorable neonatal outcomes. Implications of practice: investments in the performance of these experts is important, as their know-how to make them not medicalized through TNICEO confirms a process of humanized, safe and quality care that meets official recommendations and contributes to the change in the care model.

Obstrução do Trato Urinário Baixo Fetal / Fetal lower urinary tract obstruction

A obstrução do trato urinário baixo fetal (fetal lower urinary tract obstruction - LUTO) é uma patologia caracterizada por dilatação da bexiga e hidronefrose bilateral causada por obstrução do trato urinário inferior. Sua incidência é de 2,2 em cada 10.000 nascimentos. A etiologia da LUTO inclui a válvula da uretra posterior (VUP), atresia ou estenose uretral. O diagnóstico é feito por ultrassom, que mostra bexiga dilatada, com paredes espessas (megabexiga), e uretra posterior aumentada. O tratamento cirúrgico clássico (derivação vésico-amniótica guiada por ultrassom) estaria indicado quando o líquido amniótico normal começa a diminuir, com aumento da distensão vesical e da hidronefrose. O tratamento inclui a colocação de derivação vésico-amniótica guiado pelo ultrassom e fetoscópica com coagulação a laser. De acordo com a gravidade, a LUTO é classificada nos estágios 1,2 e 3.(AU)

The Fetal Lower Urinary Tract Obstruction (LUTO) is a spectrum of diseases characterized by bladder distension and bilateral hydronephrosis in consequence of the LUTO. The incidence is approximately 2.2 in 10,000 births and it is commonly diagnosed during the late first or early second trimester of pregnancy. The etiologies of LUTO include posterior urethral valves, urethral atresia and urethral stenosis. Complete bladder outlet obstruction (severe LUTO) is associated with high perinatal mortality due to pulmonary hypoplasia and severe renal impairment/damage. The prenatal intervention includes vesicoamniotic shunt placement guided by ultrasound and fetoscopic laser coagulation. It is suggested that LUTO patients could be categorized in three stages according to disease gravity: Stages 1, 2 and 3.(AU)

O papel do Doppler da artéria umbilical na decisão da interrupção da gestação em fetos com RCF: uma revisão de ensaios clínicos randomizados / Role of umbilical artery Doppler in the decision to deliver a pregnancy with a fetal growth restriction: a review of randomized trials

Introdução: O uso da ultrassonografia tem sido importante no âmbito da obstetrícia e a introdução da Dopplervelocimetria angariou vantagens no auxílio da avaliação da vitalidade fetal. O uso do Doppler da artéria umbilical tem apresentado melhores resultados perinatais, especialmente em fetos com RCF (restrição de crescimento fetal). A vigilância fetal em casos de RCF é indispensável na determinação do momento ideal para a interrupção da gestação, a fim de se minimizar o risco tanto de uma interrupção excessivamente prematura quanto o de um óbito fetal potencialmente evitável. Objetivo: Realizar uma revisão da literatura, a fim de avaliar o melhor momento da interrupção da gestação em fetos com RCF com Doppler da artéria umbilical alterado. Metodologia: Foi utilizada como fonte de pesquisa a base de dados eletrônica PubMed/Medline. Foram incluídos estudos randomizados que avaliaram especificamente o Doppler da artéria umbilical como método diagnóstico na decisão quanto ao momento da interrupção da gestação em situações de RCF. Foram localizados 89 resultados com a estratégia de busca, dentre os quais 22 foram considerados potencialmente elegíveis e revisados integralmente, e apenas 2 foram definitivamente elegíveis, ambos referentes a um único estudo. Resultados: Os dois artigos selecionados são estudos clínicos multicêntricos randomizados controlados, sendo que um revela os resultados a curto prazo, com 548 gestantes entre 24 e 36 semanas de gestação, e o outro, os resultados após 2 anos de acompanhamento, com 588 crianças que desenvolveram RCF durante a gestação. Os desfechos avaliados em ambos os estudos (óbito fetal ou neonatal e comprometimento neurológico no longo prazo) não foram significativamente diferentes entre grupos em que, após o diagnóstico de diástole umbilical comprometida, se realizou a interrupção precoce após corticoterapia versus vigilância com interrupção mais tardia, mediante piora no padrão do Doppler umbilical. Conclusão: Não é possível utilizar apenas o Doppler da artéria umbilical para indicar a interrupção da gestação em fetos com RCF, devendo-se associar outros métodos para a avaliação da vitalidade fetal. Mais ensaios clínicos randomizados são necessários para elucidar esta questão.(AU)

Introduction: The use of ultrassonography has been an important development in the field of obstetrics, and the introduction of Doppler assessment has gathered many advantages in the evaluation of fetal well-being. Umbilical artery Doppler has demonstrated the best perinatal results, especially in fetal growth restriction (FGR). Fetal surveillance, in these scenarios, is invaluable in determining the ideal moment for delivery, avoiding both an excessively and unnecessarily premature interruption, and a preventable intrauterine fetal demise due to an inappropriately delayed delivery. Objective: To perform a review of the literature, with the objective to evaluate the best moment of interruption of gestation in fetuses with FGR and an abnormal umbilical artery Doppler. Methodology: Electronic database PubMed/ MEDLINE was used to search and locate the studies. Randomized trials which specifically studied umbilical artery Doppler as a decision-making diagnostic study among fetuses with growth restriction were considered for inclusion in this review. There were 89 results retrieved with the search strategy, among which 22 were selected as potentially eligible, and only 2 were definitely included (both from a single study). Results: Both included papers are multicentric randomized controlled trials, the first reporting short term outcomes of 548 pregnancies between 24 and 36 weeks, and the second one reporting long-term outcomes of 588 children who had FGR, after two years of follow-up. Both short term outcomes (fetal or neonatal death) and long-term outcomes (death or disability) were not significantly different when, after diagnosing compromised umbilical end diastolic flow, immediate delivery was compared with expectant management and delayed delivery after worsening of the umbilical Doppler pattern. Conclusion: It is not possible to use only umbilical artery Doppler to decide whether to deliver a FGR or not, and that other fetal assessment methods should be associated. More randomized trials are needed to definitely answer this question.(AU)
