RESUMO
CONTEXT: The Qualineo Strategy is an effective measure for reducing neonatal mortality in regions with the highest death rates. In addition, it is a relevant Brazilian tool for strengthening teamwork and neonatal assistance. This study aims to analyze the predictors of neonatal death in the indicators of care provided by the Qualineo Strategy at a reference maternity hospital in Piauí, in the years 2021 to 2022. METHODS: This is a retrospective study of 1856 newborn records. Pearson's chi-squared test was used to assess the association between the variables; a predictive regression model was used to identify the variables that predict neonatal mortality. RESULTS: There was a significant association between all neonatal variables and the outcome of death (p < 0.05). The predictor variables for death in term newborns were the use of drugs by the mother and admission to the Neonatal Intensive Care Unit. For premature newborns, the predictor variables were, as follows: the use of cannula ventilation, an Apgar score in the 1st minute <7; and admission to the Neonatal Intensive Care Unit. CONCLUSIONS: The results will make it possible to visualize better strategies for the reality analyzed and reinforce the importance of prenatal care.

INTRODUCTION: Neonatal mortality is a global public health challenge. Guatemala has the fifth highest neonatal mortality rate in Latin America, and Indigenous communities are particularly impacted. This study aims to understand factors driving neonatal mortality rates among Maya Kaqchikel communities. METHODS: We used sequential explanatory mixed methods. The quantitative phase was a secondary analysis of 2014-2016 data from the Global Maternal and Newborn Health Registry from Chimaltenango, Guatemala. Multivariate logistic regression models identified factors associated with perinatal and late neonatal mortality. A number of 33 in-depth interviews were conducted with mothers, traditional Maya midwives and local healthcare professionals to explain quantitative findings. RESULTS: Of 33 759 observations, 351 were lost to follow-up. There were 32 559 live births, 670 stillbirths (20/1000 births), 1265 (38/1000 births) perinatal deaths and 409 (12/1000 live births) late neonatal deaths. Factors identified to have statistically significant associations with a higher risk of perinatal or late neonatal mortality include lack of maternal education, maternal height <140 cm, maternal age under 20 or above 35, attending less than four antenatal visits, delivering without a skilled attendant, delivering at a health facility, preterm birth, congenital anomalies and presence of other obstetrical complications. Qualitative participants linked severe mental and emotional distress and inadequate maternal nutrition to heightened neonatal vulnerability. They also highlighted that mistrust in the healthcare system-fueled by language barriers and healthcare workers' use of coercive authority-delayed hospital presentations. They provided examples of cooperative relationships between traditional midwives and healthcare staff that resulted in positive outcomes. CONCLUSION: Structural social forces influence neonatal vulnerability in rural Guatemala. When coupled with healthcare system shortcomings, these forces increase mistrust and mortality. Collaborative relationships among healthcare staff, traditional midwives and families may disrupt this cycle.

OBJECTIVES: To identify predictors of outcomes in severe twin oligo-polyhydramnios sequence (TOPS) with or without twin anemia-polycythemia sequence (TAPS) and/or selective fetal growth restriction (SFGR) treated by laser ablation of placental vessels (LAPV). METHODS: Analysis of cases treated from 2011 to 2022. Variables evaluated Prenatal predictors: stages of TOPS, presence of TAPS and/or SFGR; pre-LAPV fetal ultrasound parameters; peri-LAPV variables. Perinatal predictors: GA at birth; birthweight; Apgar scores; transfontanellar ultrasonography (TFUS). OUTCOME VARIABLES: fetal death, neonatal survival, infant's neurodevelopment. Binary logistic regression analyses were performed to detect predictors of outcomes. RESULTS: 265 cases were included. Predictors of post-LAPV donor fetus' death were delta EFW (p:0.045) and absent/reverse end-diastolic flow in the umbilical artery (AREDF-UA) (p < 0.001). The predictor of post-LAPV recipient fetus' death was hydrops (p:0.009). Predictors of neonatal survival were GA at birth and Apgar scores. Predictors of infant's neurodevelopment were TFUS and pre-LAPV middle cerebral artery Doppler (MCAD) for the donor twin; and pre-LAPV ductus venosus' flow and MCAD for the recipient twin. CONCLUSIONS: Prediction of fetal death, neonatal survival and infant's neurodevelopment is possible in cases of TOPS associated or not with SFGR and/or TAPS that were treated by LAPV.

[ABSTRACT]. Objective. To analyze temporal trends and inequalities in neonatal mortality between 2000 and 2020, and to set neonatal mortality targets for 2025 and 2030 in the Americas. Methods. A descriptive ecological study was conducted using 33 countries of the Americas as units of anal- ysis. Both the percentage change and average annual percentage change in neonatal mortality rates were estimated. Measurements of absolute and relative inequality based on adjusted regression models were used to assess cross-country social inequalities in neonatal mortality. Targets to reduce neonatal mortality and cross-country inequalities were set for 2025 and 2030. Results. The estimated regional neonatal mortality rate was 12.0 per 1 000 live births in 2000–2004 and 7.4 per 1 000 live births in 2020, representing a percentage change of –38.3% and an average annual per- centage change of –2.7%. National average annual percentage changes in neonatal mortality rates between 2000–2004 and 2020 ranged from –5.5 to 1.9 and were mostly negative. The estimated excess neonatal mor- tality in the 20% most socially disadvantaged countries, compared with the 20% least socially disadvantaged countries, was 17.1 and 9.8 deaths per 1 000 live births in 2000–2004 and 2020, respectively. Based on an extrapolation of recent trends, the regional neonatal mortality rate is projected to reach 7.0 and 6.6 neonatal deaths per 1 000 live births by 2025 and 2030, respectively. Conclusions. National and regional health authorities need to strengthen their efforts to reduce persistent social inequalities in neonatal mortality both within and between countries.
[RESUMEN]. Objetivo. Analizar las desigualdades en la mortalidad neonatal y las tendencias en el transcurso del tiempo entre el 2000 y el 2020, y establecer metas en materia de mortalidad neonatal para el 2025 y el 2030 en la Región de las Américas. Métodos. Se realizó un estudio ecológico descriptivo con información de 33 países de la Región de las Américas que se usaron como unidades de análisis. Se calculó tanto la variación porcentual como la varia- ción porcentual anual media de las tasas de mortalidad neonatal. Se utilizaron mediciones de la desigualdad absoluta y relativa basadas en modelos de regresión ajustados, para evaluar las desigualdades sociales en los diversos países en cuanto a la mortalidad neonatal. Se establecieron metas de reducción de la mortalidad neonatal y de las desigualdades en los diversos países para el 2025 y el 2030. Resultados. La tasa de mortalidad neonatal en la Región fue de 12,0 por 1 000 nacidos vivos en el período 2000-2004 y de 7,4 por 1 000 nacidos vivos en el 2020, lo que representa una variación porcentual del –38,3% y una variación porcentual anual media del –2,7%. Las variaciones porcentuales anuales medias de las tasas de mortalidad neonatal a nivel nacional entre el período 2000-2004 y el 2020 oscilaron entre –5,5 y 1,9, y fueron en su mayor parte negativas. El exceso de mortalidad neonatal estimado en el 20% de los países más desfavorecidos socialmente, en comparación con el 20% de los países menos desfavorecidos socialmente, fue de 17,1 muertes por 1 000 nacidos vivos en el período 2000-2004 y de 9,8 muertes por 1 000 nacidos vivos en el 2020. Al extrapolar las tendencias más recientes, se prevé que la tasa de mortalidad neonatal de la Región alcance valores de 7,0 y 6,6 muertes neonatales por 1 000 nacidos vivos en el 2025 y el 2030, respectivamente. Conclusiones. Las autoridades de salud nacionales y regionales deben fortalecer las medidas para reducir las desigualdades sociales que aún persisten en materia de mortalidad neonatal, tanto entre los distintos países como dentro de cada país.

BACKGROUND: Foreign bodies (FBs) are a common emergency in medical institutions, that can occur in any area and among people of any age, which are common public health problems. Understanding the epidemiological characteristics of FBs is crucial for their prevention and control. The purpose of this study was to analyze the epidemiological characteristics of FBs worldwide through the data from the Global Burden of Disease Study 2019 (GBD 2019). METHODS: We obtained data from the GBD 2019, which is an important public database to understand the disease burden of FBs. Joinpoint was used to analyze temporal trends in the incidence and death trends of FBs, which is widely used to study the long-term temporal trend of the burden of diseases. SaTScan was used to detect spatial-temporal clusters of pulmonary aspiration and foreign body in the airway (PAFBA), which is based on a Poisson model, scanning the number of people and diseases in the study area to obtain the spatial-temporal clusters of diseases. RESULTS: Globally, the age-standardized incidence rate (ASIR) and the age-standardized death rate (ASDR) of FBs in 2019 were 869.23/100,000 (679.92/100,000-1120.69/100,000) and 1.55/100,000 (1.41/100,000-1.67/100,000), respectively. The ASIR and ASDR showed downtrends with average annual percent changes (AAPCs) of -0.31% and - 1.47% from 1990 to 2019. Of note, the ASIR showed an uptrend during 2010-2019, especially in high, high-middle, and middle SDI regions. Stratified analysis by age group showed that ASIR increased in each age group in recent years. From 1990 to 2019, the ASDR in the over-70 age group showed an uptrend worldwide, especially in high and high-middle SDI regions. In different types of FBs, the ASDR of PAFBA was the highest. The death burden of PAFBA was mainly clustered in 82 countries during 1993-2007, such as Canada, Cuba, and Mexico. CONCLUSION: The most important goal is to improve public awareness and emergency knowledge of FBs through publicity methods, such as the internet or offline activities, and to improve laws and regulations. Additionally, different age groups need different targeted measures, such as strengthening the care of children, caring for elderly individuals, improving necessary monitoring programs and reporting systems, conducting effective hazard assessments, and publicity and education activities.

OBJECTIVES: This study aimed to analyze, in the São Paulo state of Brazil, time trends in prevalence, neonatal mortality, and neonatal lethality of central nervous system congenital malformations (CNS-CM) between 2004 and 2015. METHODS: Population-based study of all live births with gestational age ≥22 weeks and/or birthweight ≥400 g from mothers living in São Paulo State, during 2004-2015. CNS-CM was defined by the presence of International Classification Disease 10th edition codes Q00-Q07 in the death and/or live birth certificates. CNS-CM was classified as isolated (only Q00-Q07 codes), and non-isolated (with congenital anomalies codes nonrelated to CNS-CM). CNS-CM associated neonatal death was defined as death between 0 and 27 days after birth in infants with CNS-CM. CNS-CM prevalence, neonatal mortality, and lethality rates were calculated, and their annual trends were analyzed by Prais-Winsten Model. The annual percent change (APC) with 95% confidence interval (95%CI) was obtained. RESULTS: 7,237,628 live births were included in the study and CNS-CM were reported in 7526 (0.1%). CNS-CM associated neonatal deaths occurred in 2935 (39.0%). Isolated CNS-CM and non-isolated CNS-CM were found respectively in 5475 and 2051 livebirths, with 1525 (28%) and 1410 (69%) neonatal deaths. CNS-CM prevalence and neonatal lethality were stationary, however neonatal mortality decreased (APC -1.66; 95%CI -3.09 to -0.21) during the study. For isolated CNS-CM, prevalence, neonatal mortality, and lethality decreased over the period. For non-isolated CNS-CM, the prevalence increased, neonatal mortality was stationary, and lethality decreased during the period. The median time of CNS-CM associated neonatal deaths was 18 h after birth. CONCLUSIONS: During a 12-year period in São Paulo State, Brazil, neonatal mortality of infants with CNS-CM in general and with isolated CNS-CM showed a decreasing pattern. Nevertheless CNS-CM mortality remained elevated, mostly in the first day after birth.

BACKGROUND: Magnesium sulphate is the drug of choice for the prevention and treatment of women with eclampsia. Regimens for administration of this drug have evolved over the years, but there is no clarity on the comparative benefits or harm of alternative regimens. This is an update of a review first published in 2010. OBJECTIVES: To assess if one magnesium sulphate regimen is better than another when used for the care of women with pre-eclampsia or eclampsia, or both, to reduce the risk of severe morbidity and mortality for the woman and her baby. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (29 April 2022), and reference lists of retrieved studies. SELECTION CRITERIA: We included randomised trials and cluster-randomised trials comparing different regimens for administration of magnesium sulphate used in women with pre-eclampsia or eclampsia, or both. Comparisons included different dose regimens, intramuscular versus intravenous route for maintenance therapy, and different durations of therapy. We excluded studies with quasi-random or cross-over designs. We included abstracts of conference proceedings if compliant with the trustworthiness assessment. DATA COLLECTION AND ANALYSIS: For this update, two review authors assessed trials for inclusion, performed risk of bias assessment, and extracted data. We checked data for accuracy. We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS: For this update, a total of 16 trials (3020 women) met our inclusion criteria: four trials (409 women) compared regimens for women with eclampsia, and 12 trials (2611 women) compared regimens for women with pre-eclampsia. Most of the included trials had small sample sizes and were conducted in low- and middle-income countries. Eleven trials reported adequate randomisation and allocation concealment. Blinding of participants and clinicians was not possible in most trials. The included studies were for the most part at low risk of attrition and reporting bias. Treatment of women with eclampsia (four comparisons) One trial compared a loading dose-alone regimen with a loading dose plus maintenance dose regimen (80 women). It is uncertain whether either regimen has an effect on the risk of recurrence of convulsions or maternal death (very low-certainty evidence). One trial compared a lower-dose regimen with standard-dose regimen over 24 hours (72 women). It is uncertain whether either regimen has an effect on the risk of recurrence of convulsion, severe morbidity, perinatal death, or maternal death (very low-certainty evidence). One trial (137 women) compared intravenous (IV) versus standard intramuscular (IM) maintenance regimen. It is uncertain whether either route has an effect on recurrence of convulsions, death of the baby before discharge (stillbirth and neonatal death), or maternal death (very low-certainty evidence). One trial (120 women) compared a short maintenance regimen with a standard (24 hours after birth) maintenance regimen. It is uncertain whether the duration of the maintenance regimen has an effect on recurrence of convulsions, severe morbidity, or side effects such as nausea and respiratory failure. A short maintenance regimen may reduce the risk of flushing when compared to a standard 24 hours maintenance regimen (risk ratio (RR) 0.27, 95% confidence interval (CI) 0.08 to 0.93; 1 trial, 120 women; low-certainty evidence). Many of our prespecified critical outcomes were not reported in the included trials. Prevention of eclampsia for women with pre-eclampsia (five comparisons) Two trials (462 women) compared loading dose alone with loading dose plus maintenance therapy. Low-certainty evidence suggests an uncertain effect with either regimen on the risk of eclampsia (RR 2.00, 95% CI 0.61 to 6.54; 2 trials, 462 women) or perinatal death (RR 0.50, 95% CI 0.19 to 1.36; 2 trials, 462 women). One small trial (17 women) compared an IV versus IM maintenance regimen for 24 hours. It is uncertain whether IV or IM maintenance regimen has an effect on eclampsia or stillbirth (very low-certainty evidence). Four trials (1713 women) compared short postpartum maintenance regimens with continuing for 24 hours after birth. Low-certainty evidence suggests there may be a wide range of benefit or harm between groups regarding eclampsia (RR 1.99, 95% CI 0.18 to 21.87; 4 trials, 1713 women). Low-certainty evidence suggests there may be little or no effect on severe morbidity (RR 0.96, 95% CI 0.71 to 1.29; 2 trials, 1233 women) or side effects such as respiratory depression (RR 0.80, 95% CI 0.25 to 2.61; 2 trials, 1424 women). Three trials (185 women) compared a higher-dose maintenance regimen versus a lower-dose maintenance regimen. It is uncertain whether either regimen has an effect on eclampsia (very low-certainty evidence). Low-certainty evidence suggests that a higher-dose maintenance regimen has little or no effect on side effects when compared to a lower-dose regimen (RR 0.79, 95% CI 0.61 to 1.01; 1 trial 62 women). One trial (200 women) compared a maintenance regimen by continuous infusion versus a serial IV bolus regimen. It is uncertain whether the duration of the maintenance regimen has an effect on eclampsia, side effects, perinatal death, maternal death, or other neonatal morbidity (very low-certainty evidence). Many of our prespecified critical outcomes were not reported in the included trials. AUTHORS' CONCLUSIONS: Despite the number of trials evaluating various magnesium sulphate regimens for eclampsia prophylaxis and treatment, there is still no compelling evidence that one particular regimen is more effective than another. Well-designed randomised controlled trials are needed to answer this question.

BACKGROUND: The burden of maternal morbidity in neonatal outcomes can vary with the adequacy of healthcare provision and tool implementation to improve monitoring. Such information is lacking in Latin American countries, where the decrease in severe maternal morbidity and maternal death remains challenging. OBJECTIVES: To determine neonatal outcomes according to maternal characteristics, including different degrees of maternal morbidity in Latin American health facilities. METHODS: This is a secondary cross-sectional analysis of the Perinatal Information System (SIP) database from eight health facilities in five Latin American and Caribbean countries. Participants were all women delivering from August 2018 to June 2021, excluding cases of abortion, multiple pregnancies and missing information on perinatal outcomes. As primary and secondary outcome measures, neonatal near miss and neonatal death were measured according to maternal/pregnancy characteristics and degrees of maternal morbidity. Estimated adjusted prevalence ratios (PRadj) with their respective 95% CIs were reported. RESULTS: In total 85,863 live births were included, with 1,250 neonatal near miss (NNM) cases and 695 identified neonatal deaths. NNM and neonatal mortality ratios were 14.6 and 8.1 per 1,000 live births, respectively. Conditions independently associated with a NNM or neonatal death were the need for neonatal resuscitation (PRadj 16.73, 95% CI [13.29-21.05]), being single (PRadj 1.45, 95% CI [1.32-1.59]), maternal near miss or death (PRadj 1.64, 95% CI [1.14-2.37]), preeclampsia (PRadj 3.02, 95% CI [1.70-5.35]), eclampsia/HELPP (PRadj 1.50, 95% CI [1.16-1.94]), maternal age (years) (PRadj 1.01, 95% CI [<1.01-1.02]), major congenital anomalies (PRadj 3.21, 95% CI [1.43-7.23]), diabetes (PRadj 1.49, 95% CI [1.11-1.98]) and cardiac disease (PRadj 1.65, 95% CI [1.14-2.37]). CONCLUSION: Maternal morbidity leads to worse neonatal outcomes, especially in women suffering maternal near miss or death. Based on SIP/PAHO database all these indicators may be helpful for routine situation monitoring in Latin America with the purpose of policy changes and improvement of maternal and neonatal health.

BACKGROUND: COVID-19 vaccines have been shown to protect pregnant individuals against mild and severe COVID-19 outcomes. However, limited safety data are available for inactivated (CoronaVac) and mRNA (BNT162b2) vaccines during pregnancy regarding their effect on birth outcomes and neonatal mortality, especially in low- and middle-income countries. METHODS: We conducted a retrospective population-based cohort study in Rio de Janeiro, Brazil, with 17â513 singleton live births conceived between 15 May 2021 and 23 October 2021. The primary exposure was maternal vaccination with CoronaVac or mRNA BNT162b2 vaccines and sub-analyses were performed by the gestational trimester of the first dose and the number of doses given during pregnancy. The outcomes were pre-term birth (PTB), small for gestational age (SGA), low birthweight (LBW), low Apgar 5 and neonatal death. We used the Cox model to estimate the hazard ratio (HR) with a 95% CI and applied the inverse probability of treatment weights to generate adjusted HRs. RESULTS: We found no significant increase in the risk of PTB (HR: 0.98; 95% CI 0.88, 1.10), SGA (HR: 1.09; 95% CI 0.96, 1.27), LBW (HR: 1.00; 95% CI 0.88, 1.14), low Apgar 5 (HR: 0.81; 95% CI 0.55, 1.22) or neonatal death (HR: 0.88; 95% CI 0.56, 1.48) in women vaccinated with CoronaVac or BNT162b2 vaccines. These findings were consistent across sub-analyses stratified by the gestational trimester of the first dose and the number of doses given during pregnancy. We found mild yet consistent protection against PTB in women who received different vaccine platforms during the third trimester of pregnancy (any vaccines, HR: 0.78; 95% CI 0.63, 0.98; BNT162b2, HR: 0.75; 95% CI 0.59, 0.99). CONCLUSIONS: This study provides evidence that COVID-19 vaccination in all trimesters of pregnancy, irrespective of the vaccine type, is safe and does not increase the risk of adverse birth outcomes or neonatal deaths.

OBJECTIVE: To compare maternal and perinatal outcomes of migrant Venezuelan women with local pregnant patients in a Colombian institution in the context of a migratory crisis. STUDY DESIGN: This cross-sectional study included 11 304 deliveries from the Clínica de Maternidad Rafael Calvo in Cartagena de Indias, Colombia, a tertiary referral center on the north coast of Colombia. Data on maternal demographics and perinatal outcomes were obtained by chart review. RESULTS: In total, 595 patients were identified as Venezuelan migrants, and their perinatal outcomes were compared against those of 10 709 local pregnant patients. Despite similar baseline maternal conditions in both groups, poorer prenatal follow-up care (3 [1-5] vs. 5 [4-7] visits; P < 0.001) and severe complications were more common in Venezuelan migrant pregnant patients and their children. In addition, maternal hypertension was significantly more common in migrants (11.4% [68/595] vs. 8.3% [887/10709]; P = 0.009). Furthermore, in the group of pregnant migrant patients, the rates of severe maternal morbidity (13.4% [80/575] vs. 9.45%, [1013/10709]; P = 0.002), neonatal respiratory distress syndrome (22/595 [3.7%] vs. 237/10709 [2.23%]; P = 0.03), and perinatal mortality (11/586 [1.88%] vs. 67/10651 [0.63%]; P = 0.003) were significantly higher than in the local pregnant population. CONCLUSION: Forced migration during pregnancy may be associated with poorer prenatal care, which may predispose women and their newborns to more frequent adverse maternal and perinatal outcomes.

This study was performed during the anestrous, involving 140 Akkaraman Kangal ewes whose lambs had died in the neonatal stage due to pneumonia and enteritis. Intravaginal sponge containing progesterone was placed to the animals (Group 1, n = 70) on day 0 and removed after 7 days, following which 263 µg PGF2α and 500 IU eCG were administered to the sheep. Ram introduction was performed for 7 days (days 8-14), starting from the day after the removal of the intravaginal sponge (day 8). The animals in Group 2 (n = 70) were not exposed to any treatment. Ram introduction was performed simultaneously in both the groups. To determine the reproductive response, reproductive parameters such as estrous, pregnancy, multiple pregnancy, and embryonic mortality rates, number of births, number of offspring, and fertility, as well as their economic implications, were compared between groups. Each reproductive parameter exhibited a statistical difference between groups. An economically positive trend was observed in the study group compared with the control group. It was concluded that in case of lamb losses in commercial farms that derive profit from lambing, pregnancy of ewes can be achieved via sexual stimulation without waiting for the next breeding season.
Este estudo foi realizado durante o anestrous, envolvendo 140 ovelhas Akkaraman Kangal cujos cordeiros haviam morrido no estágio neonatal devido a pneumonia e enterite. A esponja intragaginal contendo progesterona foi colocada aos animais (Grupo 1, n = 70) no dia 0 e removida após 7 dias, após os quais 263 µg PGF2α e 500 UI eCG foram administrados às ovelhas. A introdução do carneiro foi realizada por 7 dias (dias 8-14), a partir do dia seguinte à remoção da esponja intravaginal (dia 8). Os animais do Grupo 2 (n = 70) não foram expostos a nenhum tratamento. A introdução do carneiro foi realizada simultaneamente em ambos os grupos. Para determinar a resposta reprodutiva, foram comparados entre os grupos parâmetros reprodutivos, tais como estrogênio, gravidez, gravidez múltipla e taxas de mortalidade embrionária, número de nascimentos, número de descendentes e fertilidade, bem como suas implicações econômicas. Cada parâmetro reprodutivo exibia uma diferença estatística entre os grupos. Uma tendência economicamente positiva foi observada no grupo de estudo em comparação com o grupo de controle. Concluiu-se que no caso de perdas de cordeiros em fazendas comerciais que obtêm lucros com a parição, a gravidez de ovelhas pode ser obtida através de estimulação sexual sem esperar pela próxima estação de reprodução.

Intrauterine growth restriction and prematurity determine low birth weight. The combination of the three conditions results in different neonatal phenotypes that interfere with child survival. Neonatal prevalence, survival and mortality were estimated according to neonatal phenotypes in the cohort of live births in 2021 in the state of Rio de Janeiro, Brazil. In this study, live births of multiple pregnancies, with congenital anomalies and inconsistencies in the information of weight and gestational age were excluded. The Intergrowth curve was used to classify weight adequacy. Mortality (< 24 hours, 1-6 and 7-27 days) and survival (Kaplan-Meier) were estimated. In total, 6.8%, 5.5%, and 9.5% of the 174,399 live births were low birth weight, small for gestational age (SGA), and premature, respectively. Considering low birth weight live births, 39.7% were SGA and 70% were premature. The neonatal phenotypes were heterogeneous according to maternal, delivery, pregnancy, and newborn characteristics. The mortality rate per 1,000 live births was high for low birth weight premature newborns, both SGA (78.1) and AGA (adequate for gestational age: 61.1), at all specific ages. Reductions in the survival rate were observed when comparing non-low birth weight and AGA term live births. The estimated prevalence values were lower than those of other studies, partly due to the exclusion criteria adopted. The neonatal phenotypes identified children who were more vulnerable and at higher risk of death. Prematurity contributed more to mortality than SGA, and its prevention is necessary to reduce neonatal mortality in the state of Rio de Janeiro.
A restrição do crescimento intrauterino e a prematuridade determinam o baixo peso ao nascer, e a combinação das três condições resulta em diferentes fenótipos neonatais que interferem na sobrevivência infantil. Foram estimadas a prevalência, a sobrevivência e a mortalidade neonatal, segundo os fenótipos neonatais, na coorte de nascidos vivos de 2021 no Rio de Janeiro, Brasil. Foram excluídos nascidos vivos de gravidez múltipla, com anomalia congênita, e com inconsistências nas informações de peso e idade gestacional. Foi utilizada a curva Intergrowth para classificar adequação do peso, e estimadas a mortalidade (< 24 horas, 1-6 e 7-27 dias) e sobrevida (Kaplan-Meier). Dos 174.399 nascidos vivos, 6,8%, 5,5% e 9,5% eram, respectivamente, baixo peso ao nascer, pequeno para idade gestacional (PIG) e prematuros. Entre nascidos vivos com baixo peso ao nascer, 39,7% eram PIG e 70%, prematuros. Os fenótipos neonatais foram heterogêneos segundo características maternas, do parto, da gestação e do recém-nascido. A taxa de mortalidade por 1.000 nascidos vivos foi elevada para neonatos de baixo peso ao nascer prematuros, tanto PIG (78,1) quanto AIG (adequado para idade gestacional: 61,1), em todas as idades específicas. Houve reduções significantes da sobrevida quando comparados aos nascidos vivos não baixo peso ao nascer, AIG termo. As prevalências estimadas mostraram menores valores que as de outros estudos, em parte pelos critérios de exclusão adotados. Os fenótipos neonatais identificaram crianças mais vulneráveis e com maior risco de morte. A prematuridade contribuiu mais para a mortalidade que a condição de PIG; sua prevenção é necessária para reduzir a mortalidade neonatal no Estado do Rio de Janeiro.

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

A case-control study was carried out to estimate risk factors for perinatal mortality in a referral hospital for high-risk pregnancies in Curitiba-PR. Sociodemographic, maternal, pregnancy and concept characteristics data were obtained from the hospital records of 316 cases and 316 controls from 2013 to 2017. A hierarchical multiple logistic regression analysis was performed, remaining in the final model variables with p < 0.05. The results show an increased risk of perinatal death in mothers with blood type B (OR = 2.82; 95%CI: 1.07-7.43), who did not undergo prenatal care (OR = 30.78; 95%CI: 4.23-224.29), fetuses with congenital malformations (OR = 63.90; 95%CI: 27.32-149.48), born under 28 (OR = 24.21; 95%CI: 1, 10-531.81) and between 28-31 weeks of gestation (OR = 6.03; 95%CI: 1.34-27.17) and birth weight below 1,000g (OR = 51.94; 95%CI: 4.31-626.46), between 1,000-1,499g (OR = 11.17; 95%CI: 2.29-54.41) and between 1,500-2,499g (OR = 2.75; 25-6.06). Concepts of pregnancies with premature outcome, low birth weight and the presence of congenital malformations are the main risk factors for perinatal death. On the other hand, adequate prenatal care is an important protective factor.
Estudo caso-controle com o objetivo de estimar os fatores de risco da mortalidade perinatal em um hospital de referência para gestações de alto risco em Curitiba-PR. Os dados de características sociodemográficas, maternas, da gestação e do concepto foram obtidos dos prontuários hospitalares de 316 casos e 316 controles do período de 2013 a 2017. Foi realizada análise de regressão logística múltipla hierarquizada, permanecendo no modelo final variáveis com p < 0,05. Os resultados mostram aumento do risco de óbito perinatal em mães com tipo sanguíneo B (OR = 2,82; IC95%: 1,07-7,43), que não realizaram pré-natal (OR = 30,78; IC95%: 4,23-224,29), conceptos com malformações congênitas (OR = 63,90; IC95%: 27,32-149,48), nascidos com menos de 28 (OR = 24,21; IC95%: 1,10-531,81) e entre 28-31 semanas de gestação (OR = 6,03; IC95%: 1,34-27,17) e peso ao nascer abaixo de 1.000g (OR = 51,94; IC95%: 4,31-626,46), entre 1.000-1.499g (OR = 11,17; IC95%: 2,29-54,41) e entre 1.500-2.499g (OR = 2,75; IC95%: 1,25-6,06). Conceptos de gestações com desfecho prematuro, baixo peso ao nascer e presença de malformações congênitas são os principais fatores de risco para o óbito perinatal. Em contrapartida, a assistência pré-natal adequada é importante fator de proteção.

Introdução: O luto perante a morte perinatal é específico e diferente de uma perda real, uma vez que a mãe nunca conheceu o objeto do seu luto e a morte repentina do bebê representa também a perda de uma identidade maternal. É neste momento, após o conhecimento de que algo que não aconteceu, que as expectativas e os desejos de gerarem uma vida ficam proibidos, e o sofrimento e a reação à perda tomam repercussões. Objetivo: Investigar as vivências de mães em luto perinatal. Método: Trata-se de uma pesquisa exploratória, com abordagem qualitativa, realizada com mulheres em luto perinatal acompanhadas pela equipe multiprofissional de uma maternidade pública da Paraíba, com idade maior ou igual a 18 anos. Utilizou-se a saturação dos dados para o fechamento amostral. Para a análise dos dados foi utilizada a técnica de Análise de Conteúdo de Bardin. Resultados: Participaram das entrevistas 18 mulheres em luto perinatal. A partir dos discursos das mulheres enlutadas foi possível elaborar duas categorias temáticas: categoria temática 1 processo de enlutamento; e categoria temática 2 processo de cuidar à parturiente. Discussão: De forma geral, observou-se que a maioria das mulheres elaborou a perda de seus bebês, atravessou o trabalho de luto, experimentando sentimentos de choque, negação, culpa, ambivalência, e, com isso, ressignificando suas dores, contudo, outras mulheres não conseguiram elaborar a perda do bebê morto. No que se refere ao processo de cuidar, observou-se, de forma geral, uma lacuna na assistência humanizada às mulheres, sobretudo no período intraparto e puerperal. Conclusão: Consideram-se urgente a elaboração e a implantação de uma política pública voltada para o luto perinatal, desde o puerpério imediato até o seu retorno domiciliar, a fim de assistir às mulheres no período puerperal, considerado o mais difícil no processo de enlutamento.
Introduction: Mourning perinatal death is specific and different from a real loss, since the mother never knew the object of her grief and the sudden death of the baby also represents the loss of a maternal identity. It is at this moment, after knowing that something did not happen, that the expectations and desires to generate a life are prohibited, and the suffering and the reaction to the loss take on repercussions. Objective: To investigate the experiences of mothers in perinatal mourning. Method: This is an exploratory research, with a qualitative approach, carried out with women in perinatal mourning accompanied by the multidisciplinary team of a public maternity hospital in Paraíba, aged 18 years or more. Data saturation was used for sample closing. Bardin's Content Analysis technique was used for data analysis. Results: 18 women in perinatal mourning participated in the interviews. From the speeches of the bereaved women, it was possible to elaborate two thematic categories: thematic category 1 process of mourning; and thematic category 2 process of caring for the parturient woman. Discussion: In general, it was observed that most women elaborated the loss of their babies, went through the work of mourning, experiencing feelings of shock, denial, guilt, ambivalence, and, with that, resignifying their pain, however, other women were unable to work through the loss of the dead baby. With regard to the care process, there was, in general, a gap in humanized care for women, especially in the intrapartum and puerperal period. Conclusion: It is considered urgent to elaborate and implement a public policy aimed at perinatal mourning, from the immediate puerperium to your return home, in order to assist women in the puerperal period, considered the most difficult in the grieving process.

BACKGROUND: In high- and middle-income countries, mortality associated to congenital diaphragmatic hernia (CDH) is high and variable. In Brazil, data is scarce regarding the prevalence, mortality, and lethality of CDH. This study aimed to analyze, in São Paulo state of Brazil, the temporal trends of prevalence, neonatal mortality and lethality of CDH and identify the time to CDH-associated neonatal death. METHODS: Population-based study of all live births with gestational age ≥ 22 weeks, birthweight ≥400g, from mothers residing in São Paulo State, Brazil, during 2004-2015. CDH definition and its subgroups classification were based on ICD-10 codes reported in the death and/or live birth certificates. CDH-associated neonatal death was defined as death up to 27 days after birth of infants with CDH. CDH prevalence, neonatal mortality and lethality were calculated and their annual percent change (APC) with 95% confidence intervals (95%CI) was analyzed by Prais-Winsten. Kaplan-Meier estimator identified the time after birth that CDH-associated neonatal death occurred. RESULTS: CDH prevalence was 1.67 per 10,000 live births, with a significant increase throughout the period (APC 2.55; 95%CI 1.30 to 3.83). CDH neonatal mortality also increased over the time (APC 2.09; 95%CI 0.27 to 3.94), while the lethality was 78.78% and remained stationary. For isolated CDH, CDH associated to non-chromosomal anomalies and CDH associated to chromosomal anomalies the lethality was, respectively, 72.25%, 91.06% and 97.96%, during the study period. For CDH as a whole and for all subgroups, 50% of deaths occurred within the first day after birth. CONCLUSIONS: During a 12-year period in São Paulo State, Brazil, CDH prevalence and neonatal mortality showed a significant increase, while lethality remained stable, yet very high, compared to rates reported in high income countries.

Abstract Objective: to present the epidemiological profile of infant mortality and neonatal and post neonatal components, in addition to the temporal dynamics of these events in Pernambuco State between 2009 and 2018. Methods: descriptive, ecological, temporal space study of infant mortality in Pernambuco between 2009 and 2018. Epidemiological and temporal space characteristics were described using the Sistema de Informação sobre Mortalidade (Mortality Information System) and the Sistema de Informação sobre Nascidos vivos.(Information System on Live Births) as data sources. Results: there were 19,436 infant deaths in the period; 13,546 (69.7%) in the neonatal period and 5,890 (30.3%) in the post neonatal period. Male (55.4%), non-white children (74.7%) with low birth weight (63.5%) predominated; mothers were aged between 20 and 29 years (46.6%), with 8-11 years of schooling (43.9%) and preterm pregnancy (65.2%). Although the infant mortality rate decreased during the analyzed decade, high rates persisted in cities in the Sertão (backwoods) and Vale do São Francisco and Araripe macroregions of health services. Conclusions: even though infant mortality declined over the years studied, it is necessary to achieve better rates and confront inequalities and other obstacles that perpetuate the event in Pernambuco State.
Resumo Objetivos: apresentar o perfil epidemiológico da mortalidade infantil e dos componentes neonatal e pós-neonatal, além da dinâmica espaço temporal desses eventos em Pernambuco, entre os anos de 2009 e 2018. Métodos: estudo descritivo e ecológico, de abordagem espaço temporal, da mortalidade infantil de Pernambuco entre 2009 e 2018. Foram descritas características epidemiológicas e espaço temporais, tendo como fonte de dados o Sistema de Informação sobre Mortalidade e o Sistema de Informação sobre Nascidos vivos. Resultados: ocorreram 19.436 óbitos infantis no período, sendo 13.546 (69,7%) no período neonatal e 5.890 (30,3%) no período pós neonatal. Predominaram crianças do sexo masculino (55,4%), não brancas (74,7%), com baixo peso ao nascer (63,5%), sendo as mães com idade entre 20 e 29 anos (46,6%), com escolaridade entre oito e 11 anos (43,9%) e com gestação pré-termo (65,2%). Houve decréscimo da taxa de mortalidade infantil durante a década analisada, entretanto elevadas taxas persistiram em municípios das Macrorregiões de saúde Sertão e Vale do São Francisco e Araripe. Conclusões: a mortalidade infantil apresentou cenário de queda ao longo dos anos estudados, todavia é necessário o alcance de melhores taxas, o enfrentamento às desigualdades e a outros entraves que perpetuam o evento no estado de Pernambuco.

Abstract Objectives: to estimate the burden of parturients, fetuses and neonate's severe morbidity and mortality and investigate the association between maternal and their conceptus outcomes. Methods: retrospective cohort of 546 parturients and their conceptus in a university hospital, reference for high-risk pregnancy, in the metropolitan region II of Rio de Janeiro State from 2015 to 2017. We classified parturients according to obstetric morbidity (OM) in direct, indirect, or mixed, and their outcomes as: 1) no severity, 2) severe complication (SC), 3) critical intervention/Intensive Care Unit, and 4) greater severity -maternal near-miss (MNM) or death. We evaluated the conceptus as neonatal near-miss (NNM) and fetal and neonatal deaths. We estimated morbimortality indicators and associated factors (multinomial logistic regression). Results: OM was frequent: 29.3% indirect, 22.3% direct, and 15.8% mixed. There were eight cases of NMM, seven with direct MO. Among the conceptus: 7.5% were NNM cases and 4.4%, deaths. The risk of severe maternal outcomes was 16.8 and neonatal, 102.6/1000 live births. Mixed race, inadequate prenatal care, CG and NMM/death, were associated with NNM. Inadequate prenatal care and maternal NM/death were associated with conceptus deaths. Conclusion: even in a reference unit, sociodemographic, and health care inequalities negatively affect mothers and, consequently, their children.
Resumo Objetivos: estimar a carga de morbidade grave e mortalidade em parturientes, fetos e neonatos e investigar a associação entre os desfechos maternos e de seus conceptos. Métodos: coorte retrospectiva de 546 parturientes e seus conceptos no hospital universitário referência para gravidez de alto risco da região metropolitana II do estado do Rio de Janeiro (ERJ), de 2015 a 2017. Classificamos as parturientes segundo morbidade obstétrica (MO) em direta, indireta e mista, e seus desfechos como: 1) sem gravidade, 2) complicação grave (CG), 3) intervenção crítica/ Unidade Terapia Intensiva e 4) maior gravidade-near miss materno (NMM) ou óbito. Avaliamos os conceptos quanto a near miss neonatal (NMN), óbitos fetais e neonatais. Estimamos indicadores de morbimortalidade, e fatores de associação (regressão logística multinomial). Resultados: MO foi frequente: 29,3% indiretas, 22,3% diretas e 15,8% mista. Ocorreram oito casos de NMM, sete com MO direta. Entre os conceptos,7,5% foram casos de NMN e 4,4%, óbitos. O risco de desfecho grave materno foi 16,8 e neonatal, 102,6 p/1000 nascidos vivos. Estiveram associados ao NMN: cor parda, pré-natal inadequado, CG e NMM/óbito; e ao óbito do concepto: pré-natal inadequado e NMM/óbito. Conclusão: mesmo em situação de referência, desigualdades sociodemográficas e assistenciais afetam negativamente mães e, consequentemente, seus conceptos.

OBJECTIVE: To analyze the causes of age-specific neonatal deaths and death-associated factors in the 2021 state of Rio de Janeiro birth cohort. METHODS: Retrospective cohort of live births (LB) followed up to 27 days of delivery (<24hs, 1-6 and 7-27 days). Data obtained from the Information Systems on Live Births (2021) and Mortality (2021/2022). We described the distributions of maternal and newborn characteristics and causes of death. We used multinomial regression models with hierarchical levels of determination of neonatal death. RESULTS: Of the 179,837 LB, 274 died within 24 hours, 447 within 1-6 days and 324 within 7-27 days. The neonatal mortality rate was 5.8 LB (CI 95%: 5.5-6.2). Neonatal survivors and deaths were heterogeneous according to the analyzed characteristics, except for the reproductive history (p<0,05). 78% of causes of death were avoidable. Causes reducible by adequate care for pregnant women (<24 hours and 1-6 days) and newborns (7-27 days) predominated. Low schooling showed a significant association for deaths between 7-27 days (ORajusted=1.3); mixed race, for deaths between 1-6 days (ORajusted=1.3), and black color for both age groups (1-6 days: ORajusted=1.5 and 7-27 days: ORajusted=1.8). Health care and biological factors of LB (intermediate and proximal levels) remained strongly associated with neonatal death, regardless of age. CONCLUSION: Causes of death, factors associated with neonatal death, and strength of association differed according to death-specific age. Preventive actions for neonatal death should consider sociodemographic vulnerabilities and intensify adequate prenatal and perinatal care.
