Sociodemographic determinants and mortality of premature newborns in a medium and low-income population in Colombia, 2017-2019 / Factores determinantes sociodemográficos y de mortalidad en recién nacidos prematuros en población de medianos y bajos ingresos en Colombia, 2017-2019

Introduction. The birth of premature babies is a public health problem with a high impact on infant morbidity and mortality. About 40% of mortality in children under five years occurs in the first month of life. Objective. To identify the association between maternal sociodemographic factors, premature birth, and mortality in newborns under 37 weeks in Santiago de Cali, 2017-2019. Materials and methods. We conducted a descriptive, cross-sectional study. We evaluated the records of Cali's Municipal Public Health Office. We calculated the crude and adjusted odd ratios and confidence intervals (95%) using the logistic regression model, data processing in Stata 16, and georeferencing the cases in the QGIS software. Results. From 2017 to 2019, premature babies in Cali corresponded to 11% of births. Poor prenatal care increased 3.13 times the risk of being born before 32 weeks (adjusted OR = 3.13; 95% CI = 2.75 - 3.56) and 1.27 times among mothers from outside the city (adjusted OR = 1.27; 95% CI = 1.15-1.41). Mortality was 4.29 per 1,000 live births. The mortality risk in newborns weighing less than 1,000 g increased 3.42 times (OR = 3.42; 95% CI = 2.85-4.12), delivery by cesarean section in 1.46 (OR = 1.46; CI 95% = 1.14-1.87) and an Apgar score - five minutes after birth- lower than seven in 1.55 times (OR = 1.55; CI 95% = 1.23-1.96). Conclusions. We found that less than three prenatal controls, mothers living outside Cali, afro-ethnicity, and cesarean birth were associated with prematurity of less than 32 weeks. We obtained higher mortality in newborns weighing less than 1,000 g.

Introducción. El nacimiento de bebés prematuros es un problema de salud pública con gran impacto en la morbimortalidad infantil: cerca del 40 % de las muertes de niños menores de cinco años sucede en el primer mes de vida. Objetivo. Identificar la asociación entre los factores sociodemográficos maternos, el parto prematuro y la mortalidad en recién nacidos menores de 37 semanas en Santiago de Cali, 2017-2019. Materiales y métodos. Se hizo un estudio descriptivo transversal. Se evaluaron los registros de la Secretaría de Salud Pública Municipal de Cali. Se calcularon las razones de probabilidad y los intervalos de confianza (95 %) crudos y ajustados mediante el modelo de regresión logística, en tanto que los datos se procesaron en Stata 16 y los casos se georreferenciaron con el programa QGIS. Resultados. Entre el 2017 y el 2019, los nacimientos de bebés prematuros en Cali correspondieron al 11 %. El control prenatal deficiente aumentó 3,13 veces el riesgo de nacer con menos de 32 semanas (OR ajustado = 3,13; IC95% = 2,75-3,56) y, en madres de municipios fuera de la ciudad, 1,27 veces (OR ajustado = 1,27; IC95% = 1,15-1,41). La mortalidad fue de 4,29 por 1.000 nacidos vivos. Nacer con un peso menor de 1.000 g aumentó el riesgo de mortalidad en 3,42 veces (OR = 3,42; IC95% = 2,85-4,12) y, un puntaje Apgar menor de siete a los cinco minutos del nacimiento, en 1,55 veces (OR=1,55; IC95% = 1,23-1,96). Conclusiones. Se encontró que tener menos de tres controles prenatales, la procedencia de la madre fuera de Cali, ser afrodescendiente y el parto por cesárea, estaban asociados significativamente con la prematuridad de menos de 32 semanas. Hubo mayor mortalidad en los recién nacidos con menos de 1.000 gramos al nacer.

Especificidades técnicas no tamponamento uterino com balões e algumas dificuldades técnicas / Technical specificities in uterine tamponade with balloons and some technical difficulties

A mortalidade materna é inaceitavelmente alta. A hemorragia pós-parto encontra- se na primeira posição no mundo, tendo como principal causa específica a atonia uterina. Eventualmente, as medidas iniciais e a terapia farmacológica não são efetivas no controle do sangramento, impondo a necessidade de tratamentos invasivos, cirúrgicos ou não. Entre esses, o tamponamento uterino com balão requer recursos locais mínimos e não exige treinamento extensivo ou equipamento muito complexo. Entretanto, algumas dificuldades podem ocorrer durante a inserção, infusão ou manutenção do balão na cavidade uterina, com especificidades relacionadas à via de parto. Após o parto vaginal, a dificuldade mais prevalente é o prolapso vaginal do balão. Na cesárea, as principais dificuldades são a inserção e o posicionamento do balão na cavidade uterina, principalmente nas cesáreas eletivas. Este artigo revisa e ilustra as principais dificuldades e especificidades relacionadas ao tamponamento uterino com balões.

Maternal mortality is unacceptably high. Postpartum hemorrhage is ranked first in the world, with the main specific cause being uterine atony. Eventually, initial measures and pharmacological therapy are not effective in controlling bleeding, imposing the need for invasive treatments, surgical or not. Among these, uterine balloon tamponade requires minimal local resources and does not require extensive training or very complex equipment. However, some difficulties may occur during insertion, infusion, or maintenance of the balloon in the uterine cavity, with specificities related to the mode of delivery. After vaginal delivery, the most prevalent difficulty is vaginal balloon prolapse. In cesarean section, the main difficulty is the insertion and positioning of the balloon in the uterine cavity, especially in elective cesarean sections. This article reviews and illustrates the main difficulties and specificities related to uterine balloon tamponade.

Pregnant women in group A had a higher probability of cesarean section (odds ratio (OR) 1.76; 95% confidence interval (95%CI), 1.03 - 2.98), prolonged labor (OR 2.09; 95%CI, 1.23 - 3.53) and prolonged pregnancy (OR 2.30; 95%CI, 1.32 - 4.01) compared to pregnant women in group C. The pregnant women in group B did not show statistically significant differences in the frequency of obstetric variables compared to the pregnant women in group C (p = ns). Conclusion : There was a significant association between pregestational obesity and the risk of birth alterations.

The effect of Pilates on pain during pregnancy and labor: a systematic review and meta-analysis

SUMMARY OBJECTIVE: This systematic review and meta-analysis study was conducted to reveal the effect of Pilates on pain during pregnancy and labor. METHODS: The PubMed, ScienceDirect, MEDLINE, Ovid, EBSCO, CINAHL Plus, Cochrane Library databases, and Google Scholar databases were used to access the articles published in international journals, and the Dergipark, Turkish Clinics, and ULAKBİM databases were scanned to access the articles published in national journals between October 30 and November 30, 2022. The data were analyzed using Review Manager 5.4. RESULTS: This study included four articles. According to the meta-analysis results, it was elucidated that Pilates exercise during pregnancy was not statistically effective in reducing pain during pregnancy (Z=0.61, p=0.54), but it was effective in reducing pain intensity during labor (Z=11.20, p<0.00001). CONCLUSION: This study concluded that Pilates exercise was not effective in reducing pain during pregnancy but was effective in reducing labor pain. There is a need for more research on the subject.

Is it Necessary to Evaluate Fear of Childbirth in Pregnant Women? A Scoping Review / É necessário avaliar o medo do parto em gestantes? Uma revisão de escopo

Abstract Objective To review concepts, definitions, and findings about fear of childbirth (FOC). Methods A bibliographic review was carried out through the main scientific databases in 2020. Results All 32 articles considered potentially relevant were analyzed. A recent study suggests that the global prevalence of FOC can reach up to 14%. Factors such as parity, gestational age, previous birth experience, age and nationality of the woman seem to influence FOC. Conclusion Fear of childbirth could be related to an increased risk of adverse obstetric outcomes such as maternal request for cesarean delivery, preterm birth, prolonged labor, postpartum depression, and post-traumatic stress. These evidence highlight the importance of the discussion regarding this topic.

Resumo Objetivo Revisar conceitos, definições e achados sobre medo do parto (MDP). Métodos Foi realizada uma revisão bibliográfica nas principais bases de dados científicas em 2020. Resultados Foram analisados todos os 32 artigos considerados potencialmente relevantes. Um estudo recente sugere que a prevalência global do MDP pode chegar a 14%. Fatores como paridade, idade gestacional, experiência anterior de parto, idade da mulher e nacionalidade parecem influenciar o MDC. Conclusão O MDC pode estar relacionado ao aumento do risco de desfechos obstétricos adversos, como solicitação materna de cesariana, parto prematuro, trabalho de parto prolongado, depressão pós-parto e estresse pós-traumático. Estas evidências destacam a importância da discussão sobre este tema.

Índices de vascularización cervical en la predicción de parto pretérmino inminente

Objetivo. Establecer la utilidad de los índices de vascularización cervical en la predicción de parto pretérmino inminente. Diseño. Estudio de casos-controles. Institución. Hospital Central "Dr. Urquinaona", Maracaibo, Venezuela. Participantes. Pacientes con parto pretérmino en los siguientes 7 días (grupo A) y embarazadas con parto pretérmino más allá de los 7 días (grupo B). Métodos. Las embarazadas fueron evaluadas utilizando ecografía transvaginal y seguidas hasta el parto. Principales medidas de resultado. Características generales, índices de vascularización cervical (índice de vascularización, índice de flujo e índice de vascularización / flujo), parto pretérmino inminente y eficacia pronóstica. Resultados. Fueron incluidas 350 pacientes, 75 mujeres presentaron parto pretérmino inminente (grupo A) y 251 pacientes fueron consideradas como controles (grupo B). Las pacientes del grupo A tuvieron valores significativamente más bajos del índice de vascularización e índice de flujo comparado con el grupo B (p = 0,0122 y p < 0,0001, respectivamente). Las pacientes del grupo B presentaron valores significativamente más altos de índice de vascularización / flujo comparadas con las pacientes del grupo A (p = 0,0103). Los tres índices y la combinación de estos no mostraron capacidad de discriminación de parto pretérmino inminente. Conclusiones. Las pacientes con parto pretérmino inminente presentan diferencias significativas en los índices de vascularización comparado con las pacientes que presentan parto pretérmino más allá de los 7 días de la evaluación ecográfica. Sin embargo, no son útiles en la predicción del parto pretérmino inminente.

Objective: To establish the usefulness of cervical vascularization low he in the prediction of impending preterm labor. Design: Case-control study. Institution: "Dr. Urquinaona" Central Hospital, Maracaibo, Venezuela. Participants: Patients with preterm delivery within 7 days (group A) and pregnant women with preterm delivery beyond 7 days (group B). Methods: Pregnant women were evaluated using transvaginal ultrasound and followed until delivery. Main outcome measures: General characteristics, cervical vascularity low he (vascularity index, low index and vascularity / low index), impending preterm delivery, and prognostic efficacy. Results: A total of 350 patients were included, 75 women presented imminent preterm labor (group A) and 251 patients were considered as controls (group B). Patients in group A had significantly lower values of vascularization index and low index compared to group B (p = 0.0122 and p < 0.0001, respectively). Patients in group B had significantly higher values of vascularization / low index compared to patients in group A (p = 0.0103). The three low he and the combination of these did not show the ability to discriminate imminent preterm labor. Conclusions: Patients with imminent preterm labor showed significant differences in the vascularization low he compared to patients presenting preterm labor beyond 7 days of ultrasound evaluation. However, they are not useful in predicting impending preterm labor.

Parámetros del líquido amniótico para diagnóstico de respuesta inflamatoria en parto pretérmino / Amniotic fluid parameters for the diagnosis of inflammatory response in preterm delivery

OBJETIVO: Evaluar el rendimiento del Gram, la glucosa y los leucocitos en líquido amniótico para el diagnóstico de respuesta inflamatoria fetal y materna en pacientes con parto pretérmino. MÉTODO: Estudio de rendimiento de pruebas diagnósticas. Se incluyeron 63 pacientes a quienes se les realizó amniocentesis por sospecha de infección intraamniótica. Se estudió la placenta y se comparó con el Gram, la glucosa y el recuento de leucocitos en líquido amniótico para ver su relación con la respuesta inflamatoria. Se evaluaron la sensibilidad, la especificidad, las razones de verosimilitud (LR, likelihood ratio), los valores predictivos y el valor de kappa. RESULTADOS: Las pruebas con mejor rendimiento fueron en conjunto la glucosa 50/mm3 en líquido amniótico, con una especificidad del 94,3% (intervalo de confianza del 95% [IC95%]: 84,6-98,1), LR + 8,83 (IC95%: 2,5-31,2) y kappa de 0,48 (IC95%: 0,15-0,82). También se consideró la propuesta de un nuevo punto de corte para el recuento de leucocitos en líquido amniótico en la respuesta inflamatoria fetal. CONCLUSIONES: La combinación del recuento de leucocitos en líquido amniótico y los valores de glucosa mejora el rendimiento para el diagnóstico de respuesta inflamatoria fetal en comparación con la histopatología de la placenta, lo que proporciona información útil para el enfoque de los recién nacidos.

OBJECTIVE: To evaluate the performance of Gram, glucose and leukocytes in amniotic fluid for the diagnosis of fetal and maternal inflammatory response in patients with preterm delivery. METHOD: A diagnostic performance test study was carried out. Sixty-three patients with preterm labor were included who underwent amniocentesis due to suspected intra-amniotic infection. Histopathology of the placenta was studied and compared with the Gram result, glucose and leukocyte count in amniotic fluid, and their relationship with the maternal and fetal inflammatory response. Sensitivity, specificity, likelihood ratios, predictive values, and kappa were evaluated. RESULTS: The tests with the best performance were overall glucose 50/mm3 in amniotic fluid for the diagnosis of the fetal inflammatory response, with a specificity of 94.3% (95% confidence interval [95% CI]: 84.6-98.1%), likelihood positive ratio 8.83 (95% CI: 2.5-31.2) and kappa of 0.48 (95% CI: 0.15-0.82). A new cut-off point for leukocyte count in amniotic fluid to diagnose fetal inflammatory response was proposed. CONCLUSIONS: The combination of amniotic fluid leukocyte count and amniotic fluid glucose values improves performance for the diagnosis of inflammatory response compared with placental histopathology, providing useful information for newborns approach.

¿La progesterona natural micronizada previene el trabajo de parto pretérmino?: Revisión sistemática de literatura / Does Natural Micronized Progesterone Prevent Preterm Labor?: Systematic Literature Review / A progesterona natural micronizada previne o trabalho de parto prematuro?: Revisão sistemática da literatura

Introducción. La progesterona es una hormona que favorece el mantenimiento del embarazo, es la protagonista de la fisiopatología del trabajo de parto pretérmino. De esta manera, se propone realizar una revisión sistemática que permita demostrar la utilidad de la progesterona natural micronizada en la mitigación de los efectos deletéreos del trabajo de parto pretérmino. Metodología. Revisión sistemática en la que se utilizaron los términos "MeSH" y "No ­ MeSH". Se empleó el programa "Publish or Perish" y bases de datos como: Medline, PubMed, Embase, Clinical Key, Cochrane Library, Scopus y Google Scholar. Se incluyeron artículos de revisión, meta-análisis, artículos originales (publicaciones preliminares o completas), resúmenes de congresos, seminarios publicados, libros de texto, protocolos hospitalarios regionales y consensos nacionales, en donde cada autor evaluó individualmente cada artículo y aplicó la herramienta CASPE. Resultados. En la literatura no es posible encontrar pautas concisas internacionales sobre el uso de la progesterona micronizada frente a la amenaza de trabajo de parto pretérmino (TPP). En general, para la mitigación del trabajo de parto, según lo analizado por los autores, se recomienda usar progesterona natural micronizada en cápsulas de 100 a 400 mg/día vía oral o 100 a 200 mg cada 12 a 24 horas vía vaginal. Desde la semana 16 hasta la semana 36 de gestación por vía oral y desde la semana 24 a 34 de gestación por vía vaginal. Discusión. El uso de la progesterona micronizada ha demostrado mitigar complicaciones posteriores al trabajo de parto pretérmino, sin embargo, no hay consenso sobre la dosificación y las vías de administración. Sumado a lo anterior, los estudios analizados pueden contener sesgos, por lo que se deja a elección del clínico el uso este medicamento. Conclusiones. La progesterona natural micronizada podría ser empleada para mitigar el trabajo de parto pretérmino según los artículos analizados por los autores a lo largo de la revisión. Sin embargo, se necesitan más estudios para legitimar dicha hipótesis.

Introduction. Progesterone is a hormone that favors maintaining pregnancy. It is the protagonist of the physiopathology of preterm labor. In this sense, a systematic review is proposed to demonstrate the usefulness of natural micronized progesterone in mitigating the harmful effects of preterm labor. Methodology. A systematic review in which the terms "MeSH" and "No ­ MeSH" were used. The "Publish or Perish" program was used, as well as databases, such as: Medline, PubMed, Embase, Clinical Key, Cochrane Library, Scopus, and Google Scholar. Review and meta-analysis articles, original articles (preliminary or complete publications), congress summaries, published seminars, textbooks, regional hospital protocols and national consensuses were included, in which each author individually assessed each article and applied the CASPE tool. Results. It was not possible to find concise international guidelines on using micronized progesterone for the threat of preterm labor (PTL) in literature. According to what the authors analyzed, for the mitigation of labor it is generally recommended the use of natural micronized progesterone in 100 to 400 mg/day capsules orally or 100 to 200 mg every 12 to 24 hours through the vagina. From week 16 to week 36 of pregnancy orally and from week 24 to 34 through the vagina. Discussion. Using micronized progesterone has demonstrated mitigating complications subsequent to preterm labor. However, there is no consensus on dosage and routes of administration. Added to the above, the analyzed studies may contain biases, reason why using this medication is left to the physician's discretion. Conclusions. Natural micronized progesterone can be used to mitigate preterm labor according to the articles the authors analyzed throughout the review. However, more studies are needed to validate this hypothesis.

Assessing the duration of obstetric analgesia and the time elapsed between analgesia and delivery. Observational trial / Evaluación de la duración de la analgesia obstétrica y del tiempo entre la analgesia y el parto. Estudio observacional

Abstract Introduction: The duration of labor and the immediate puerperium are affected by obstetric and maternal-fetal factors. Interventions to provide obstetric analgesia may prolong the hospital stay. Objective: To characterize the procedure for obstetric analgesia and describe the time elapsed between analgesia and delivery and postpartum surveillance in healthy mothers. Methods: Observational, descriptive trial. The time elapsed between analgesia and delivery, and postpartum surveillance were measured in healthy pregnant women with vaginal delivery and a prescription of a neuraxial analgesia technique. Results: 226 patients were included. The mean time elapsed between analgesia an delivery was 4 hours (IQR 3-7). 50.7 % (n=114) received early analgesia (neuraxial technique with ≤ 4 centimeters of cervical dilatation), of which 48.2 % (n = 109) experienced a duration of analgesia until delivery longer than expected. The mean cervical dilatation at the time of the neuraxial approach was 4 centimeters (IQR 4-6) and the epidural technique was the most frequently used - 92.9 % (n = 210). The mean postpartum surveillance was 20 hours (IQR 15-27). Conclusions: Half of the patients included received early analgesia and around fifty percent of them took longer than expected in completing delivery. The postpartum surveillance time was consistent with the provisions of the Ministry of Health and with the current trend of a short postpartum surveillance aimed at early hospital discharge and the benefits thereof.

Resumen Introducción: La duración del trabajo de parto y del puerperio inmediato se afectan por factores obstétricos y maternofetales. Las intervenciones para brindar analgesia obstétrica pudieran prolongar el tiempo total de estancia hospitalaria. Objetivo: Caracterizar el procedimiento de analgesia obstétrica y describir los tiempos entre analgesia y parto y vigilancia posparto en maternas sanas. Métodos: Estudio descriptivo observacional. Se midieron los tiempos entre analgesia y parto y vigilancia posparto en gestantes sanas, cuya vía final del parto fuera vaginal con indicación y aplicación de alguna técnica de analgesia neuroaxial. Resultados: Se incluyeron 226 pacientes. La mediana del tiempo de analgesia hasta el parto fue de 4 horas (RIC 3-7); el 50,7 % (n = 114) recibió analgesia temprana (técnica neuroaxial a ≤ 4 centímetros de dilatación cervical), de las cuales el 48,2 % (n = 109) tuvo un tiempo de analgesia hasta el parto mayor al esperado. La mediana de dilatación cervical al momento del abordaje del neuroeje fue de 4 centímetros (RIC 4-6) y la técnica epidural fue la más frecuente, 92,9 % (n = 210). La mediana de tiempo de vigilancia posparto fue de 20 horas (RIC 15-27). Conclusiones: La mitad de las pacientes incluidas recibió analgesia temprana y cerca de la mitad tardó más de lo esperado en finalizar su gestación. El tiempo de vigilancia posparto fue acorde con lo establecido por el Ministerio de Salud y con la tendencia actual de una vigilancia posparto corta que apunte a un alta temprana y sus beneficios.

Lactobacilluscrispatus dominance in the vaginalmicrobiome reduces the occurrence of spontaneouspreterm birth in women with a short cervical length / Dominância de Lactobacillus crispatus no microbioma vaginal reduz a ocorrênciade parto prematuro espontâneo em mulheres com encurtamento do colo uterino

Introduction: The majority of pregnant women with a short cervix will deliver at term and, thus, may unnecessarily receive advanced monitoring and treatment. It is still necessary to define more accurately which sub-population of women with a short cervix is at elevated risk for early delivery. Objective: To determine if vaginal microbiome composition influenced the rate of spontaneous preterm birth in women with a short cervical length. Methods: In an exploratory, observational prospective study, vaginal secretions were obtained from 591 women at 21­24 week gestation. Vaginal microbiome composition was determined by analyzing the V1­V3 region of the bacterial 16S ribosomal RNA gene. Results: Lactobacillus crispatus was numerically dominant in the vagina in 41.7% of subjects, followed by L. iners in 32% and Gardnerella vaginalis in 12%. In women whose cervix was ≤25mm, the sensitivity to predict an spontaneous preterm birth was 11.8%. However, when L. crispatus was not the dominant vaginal bacterium, this sensitivity increased to 81.8%. Similarly, in women with a cervical length ≤30mm, the sensitivity to predict an spontaneous preterm birth increased from 21.7 to 78.3% when L. crispatus was not the dominant vaginal bacterium.In women with a prior spontaneous preterm birth and a cervix ≤25 or ≤30mm, L. crispatus dominance was also associated with a reduced rate of spontaneous preterm birth in the current pregnancy (p<0.001). Conclusion: In pregnant women with a cervix ≤25mm or ≤30mm, the risk for an spontaneous preterm birth is increased if L. crispatus is not dominant in the vagina.

Introdução: A maioria das mulheres grávidas com colo do útero curto dará à luz a termo e, portanto, pode receber desnecessariamente monitoramento e tratamento avançados. Permanece a necessidade de definir com mais precisão qual subpopulação de mulheres com colo do útero curto está em risco elevado de parto prematuro. Objetivo: Determinar se a composição do microbioma vaginal influenciou a taxa de parto prematuro espontâneo em mulheres com colo curto. Métodos: Em um estudo prospectivo exploratório observacional, os conteúdos vaginais foram obtidos de 591 mulheres com 21­24 semanas de gestação. A composição do microbioma vaginal foi determinada pela análise da região V1­V3 do gene de RNA ribossômico bacteriano 16S. Resultados: Lactobacilluscrispatus foi numericamente dominante na vagina em 41,7% dos indivíduos, seguido por L. iners em 32% e Gardnerella vaginalis em 12%. Em mulheres cujo colo do útero era <25 mm, a sensibilidade para prever uma taxa de parto prematuro espontâneo foi de 11,8%. No entanto, quando L. crispatus não era a bactéria vaginal dominante, essa sensibilidade aumentou para 81,8%. Da mesma forma, em mulheres com comprimento cervical <30 mm, a sensibilidade para prever uma taxa de parto prematuro espontâneo aumentou de 21,7 para 78,3% quando L. crispatus não era a bactéria vaginal dominante. Em mulheres com taxa de parto prematuro espontâneo anterior e colo do útero <25 ou <30 mm, a dominância de L. crispatus também foi associada a uma taxa reduzida de taxa de parto prematuro espontâneo na gravidez atual (p<0,001). Conclusão: Em mulheres grávidas com colo do útero <25 ou <30 mm, o risco de parto prematuro espontâneo é aumentado se L. crispatus não for dominante na vagina.

Macrosomía fetal y factores de riesgo asociados en la provincia Camagüey

Introducción: La macrosomía fetal, de manera tradicional, ha sido definida por un peso arbitrario al nacer; la misma, ya sea definida por un límite de peso o grande para la edad gestacional, se asocia con numerosas complicaciones perinatales y maternas. Objetivo: Describir los factores de riesgo asociados a la macrosomía fetal en los partos del Hospital Universitario Ginecobstétrico Provincial Ana Betancourt de Mora durante el año 2019. Métodos: Se realizó un estudio observacional descriptivo de corte transversal. El universo quedó constituido por la totalidad de gestantes que tuvieron recién nacidos con peso al nacimiento mayor o igual a 4 000 gramos, el cual ascendió a 526 gestantes. Se utilizó estadística descriptiva. Se calculó media y desviación estándar a las variables cuantitativas. Resultados: Las gestantes estudiadas tenían una media de edad de 27,86 años y un IMC a la captación como promedio de 26,77 con un valor medio de ganancia de peso de 13,68 Kg. Entre los 26 y 35 años hubo 290 gestantes con recién nacidos macrosómicos, respecto a la paridad las que paren sin experiencia de este reunió a 222 grávidas. En las embarazadas catalogadas de sobrepeso con ganancia de 10 a 15 kg se reúnen 104 de los recién nacidos macrosómicos. Respecto al tipo de parto la cesárea representó el 61,4 %. Se observó en 40 gestantes la presencia de diabetes gestacional o pregestacional y preeclampsia respectivamente. Conclusiones: La ganancia excesiva de peso en gestantes con evaluación nutricional de sobrepeso u obesas tuvo la mayor incidencia en la génesis de la macrosomía en los recién nacidos.

Introduction: Fetal macrosomia has traditionally been defined by an arbitrary birth weight. Fetal macrosomia, whether defined by borderline weight or large for gestational age, is associated with numerous perinatal and maternal complications. Objective: To describe the risk factors associated with fetal macrosomia in deliveries at Ana Betancourt de Mora Provincial Gyneco-Obstetric University Hospital during 2019. Methods: A cross-sectional descriptive observational study was carried out. The study universe was made up of all pregnant women who had newborns with a birth weight greater than or equal to 4 000 grams, which amounted to 526 pregnant women. Descriptive statistics were used. Average and standard deviation were calculated for the quantitative variables. Results: The studied pregnant women had an average age of 27.86 years and an average BMI at uptake of 26.77 with an average value of weight gain of 13.68 Kg. Between 26 and 35 years there were 290 pregnant women with newborn macrosomic births, with respect to parity those who give birth without experience of this brought together 222 gravid women. In pregnant women classified as overweight with a gain of 10 to 15 kg, 104 of the macrosomic newborns are gathered. Regarding the type of delivery, cesarean section represented 61.4%. The presence of gestational or pregestational diabetes and preeclampsia, respectively, was observed in 40 pregnant women. Conclusions: The excessive weight gain in pregnant women with nutritional evaluation of overweight or obese were those that had the highest incidence in the genesis of macrosomia in newborns.

Efficacy of Doula delivery combined with painless delivery and its effects on pregnancy outcome / 中国基层医药

Objective:To investigate the efficacy of Doula delivery combined with painless delivery and its effects on pregnancy outcome.Methods:A total of 150 parturient women who underwent delivery in the First People's Hospital of Yongkang from June 2019 to June 2020 were included in this study. They were randomly assigned to undergo either conventional delivery (control group, n = 75) or Doula delivery combined with painless delivery (observation group, n = 75). Analgesic effect, mode of delivery, duration of labor and pregnancy outcome as well as mood score before and after intervention were compared between the two groups. Results:Total analgesia-effective rate in the observation group was significantly higher than that in the control group [100.00% (75/75) vs. 65.33% (49/75), χ2 = 31.45, P < 0.05]. Vaginal delivery rate in the observation group was significantly higher than that in the control group [84.00% (63/75) vs. 66.67% (50/75), χ2 = 6.60, P < 0.05]. The length of the first stage of labor, the second stage of labor, the third stage of labor and total labor length in the observation group were (398.42 ± 35.41) minutes, (43.65 ± 5.78) minutes, (8.36 ± 1.08) minutes and (450.87 ± 37.98) minutes, which were significantly shorter than those in the control group [(543.21 ± 47.87) minutes, (76.73 ± 16.56) minutes, (9.76 ± 1.23) minutes, (629.34 ± 45.26) minutes, t = 21.05, 16.33, 7.40, 26.15, all P < 0.05]. The incidence of neonatal asphyxia, fetal distress and postpartum hemorrhage in the observation group were [1.33% (1/75), 2.67% (2/75) and 2.67% (2/75), respectively, which were significantly lower than those in the control group [13.33% (10/75), 17.33% (13/75), 18.67% (14/75), χ2 = 7.94, 8.96, 10.07, all P < 0.05]. Self-rating Anxiety Scale score and Self-Rating Depression Scale score in the observation group were (43.25 ± 4.28) points and (40.28 ± 3.45) points, which were significantly lower than those in the control group [(52.12 ± 3.95) points, (47.79 ± 3.72) points, t = 13.18, 12.81, both P < 0.05). Conclusion:Doula delivery combined with painless delivery can relieve women's emotional changes, alleviate pain, shorten labor duration, and improve pregnancy outcomes.

Application of unprotected perineum delivery technique for natural childbirth in primiparas / 中国基层医药

Objective:To investigate the application effects of unprotected perineum delivery technique for normal vaginal delivery in primiparas.Methods:A total of 260 primiparas who underwent natural childbirth in Tengzhou Central People's Hospital between January 2019 and September 2020 were included in this study. They were randomly assigned to undergo childbirth either with an unprotected perineum delivery technique (study group, n = 130) or the conventional delivery technique (control group, n = 130). Delivery-related indicators were compared between the two groups. Results:The rate of first-degree perineal tear in the study and control groups was 71.52% and 29.23%, respectively, the rate of second-degree perineal tear were 7.16% and 3.16%, respectively, and the episiotomy rate in the two groups were 21.32% and 67.51%, respectively. There were significant differences in rate of first-degree perineal tear, rate of second-degree perineal tear and episiotomy rate between the two groups ( χ2 = 7.19, 7.03, 8.35, all P < 0.05). The length of hospital stay in the study and control group was 3.27 ± 5.79 days and 5.18 ± 7.26 days, respectively. The numerical rating scale score of postpartum perineal pain in the two groups was 1.23 ± 2.51 points and 3.24 ± 2.79 points, respectively. The incidence of postpartum complications was 3.33% and 11.67%, respectively. There were significant differences in length of hospital stay, numerical rating scale score of postpartum perineal pain and incidence of postpartum complications between the two groups ( t = 2.23, 2.06, χ2 = 2.52, all P < 0.05). There were no significant differences in length of second stage of labor and Apgar score in new born infants between the study and control groups (all P > 0.05). Conclusion:Unprotected perineum delivery technique can greatly decrease episiotomy rate, alleviate perineal tear, reduce pain, reduce complications, shorten length of hospital stay, and improve quality of obstetric care.

Combined application of intraspinal analgesia, bilateral pudendal nerve block anesthesia and modified perineal protection in midwifery / 中国基层医药

Objective:To investigate the clinical efficacy of intraspinal analgesia, pudendal nerve block anesthesia and modified perineal protection in combination in midwifery.Methods:A total of 160 primiparous women who were subjected to full-term vaginal delivery in Suqian Hospital of Nanjing Drum Tower Hospital Group between January 2019 and January 2021 were included in this study. They were randomly assigned to undergo either bilateral pudendal nerve block combined with modified perineal protection (control group, n = 80) or intraspinal analgesia, pudendal nerve block anesthesia and modified perineal protection in combination (observation group, n = 80). Each clinical index was compared between the control and observation groups. Results:Duration of labor in the observation group was significantly shorter than that in the control group [(7.23 ± 2.11) hours vs. (9.35 ± 3.79) hours, t = 4.27, P < 0.05). Cesarean section rate in the observation group was significantly lower than that in the control group [8.7% (7/80) vs. 52.5% (42/80), χ 2 = 17.18, P < 0.05]. Incidence of perineal tears in the observation group was significantly lower than that in the control group [8.7% (7/80) vs. 32.5% (26/80), χ 2 = 15.48, P < 0.05]. Third-degree perineal tears occurred in neither group. Time of postpartum off-bed ambulation and length of postpartum hospital stay in the observation group were (1.37 ± 0.13) days and (3.22 ± 0.31) days, respectively, which were significantly shorter than those in the control group [(2.52 ± 0.22) days, (5.23 ± 0.62) days, t = 25.90, 25.94, both P < 0.05). The incidence of complications in the observation group was significantly lower than that in the control group [7.5% (6/80) vs. 23.7% (19/80), χ 2 = 8.01, P < 0.05]. There were no significant differences in incidence of neonatal asphayxia, 2-hour postpartum hemorrhage and postpartum hemorrhage between the two groups (all P > 0.05). Conclusion:During midwifery of full-term vaginal delivery, combined application of intraspinal analgesia, bilateral pudendal nerve block anesthesia and modified perineal protection can shorten duration of labor and decrease cesarean section rate.

Characterization of pregnant women who gave birth in 2016 at the Hospital de La Samaritana, Bogotá, Colombia / Caracterización de gestantes con atención del parto durante 2016 en el Hospital Universitario de La Samaritana, Bogotá, Colombia

Abstract Introduction: Maternal mortality and severe maternal morbidity are serious public health problems, so it is essential to work on the identification, recognition and situation analysis of patients treated at high-risk pregnancy centers. Objectives: To characterize the pregnant women treated at the Hospital Universitario de la Samaritana (HUS), Bogotá, Colombia, from a demographic, social and clinical point of view in order to identify common factors that may be intervened and, thus, avoid adverse outcomes. Materials and methods: Cross-sectional study. 785 medical records of patients with a gestational age >24 weeks treated at the HUS in 2016 were analyzed. Sociodemographic data were collected, as well as data on the following variables: history of diseases, antenatal care, biopsychosocial risk, and obstetric outcomes. A univariate analysis was performed for each variable; measures of central tendency and dispersion and absolute and relative frequencies were calculated for quantitative and qualitative variables, respectively. Maternal health indicators were also calculated. Results: 47.51% of the pregnant women had a low educational level, 34.39% were single mothers, 32.10% had a previous comorbidity, and 5.85% had insufficient antenatal care. The proportion of preterm births was 23.6 (95%CI: 20.63%-26.69%), the severe maternal morbidity ratio was 157.96/1 000 live births, and the maternal mortality rate was 246/100 000 live births. Conclusions: Pregnant women treated at the HUS are mainly young women from areas where the health system is not easily accessible, and who have insufficient antenatal care and a low schooling level. This population has a high rate of severe maternal morbidity and maternal mortality compared to the national reference value, so they would benefit from educational interventions or risk approaches that prioritize these factors in order to prevent adverse maternal outcomes.

Resumen Introducción. La mortalidad materna y la morbilidad materna extrema son serios problema de salud pública, por lo que es fundamental trabajar en la identificación, reconocimiento y análisis situacional de las pacientes que acuden a los centros de alto riesgo obstétrico. Objetivos. Caracterizar las gestantes atendidas en el Hospital Universitario de la Samaritana (HUS), Bogotá, Colombia, desde el punto de vista demográfico, social y clínico con el fin de identificar factores en común potencialmente intervenibles y, de esta forma, evitar desenlaces adversos. Materiales y métodos. Estudio transversal. Se analizaron 785 historias clínicas de pacientes con edad gestacional >24 semanas atendidas durante 2016 en el HUS. Se recolectaron datos sociodemográficos y sobre las siguientes variables: antecedentes patológicos, controles prenatales, riesgo biopsicosocial y desenlaces obstétricos. Se realizó análisis univariado de cada variable: para las variables cuantitativas se calcularon medidas de tendencia central y de dispersión, mientras que para las cualitativas, frecuencias absolutas y relativas. También se calcularon indicadores de salud materna. Resultados. 47.51% de las gestantes tenían un bajo nivel educativo, 34.39% eran madres solteras, 32.10% tenían comorbilidad previa y 5.85% no asistieron a ningún control prenatal. La proporción de parto pre-término fue de 23.6 (IC95%:20.63%-26.69%), la razón de morbilidad materna extrema fue 157.96/1 000 nacidos vivos y la tasa de mortalidad materna, 246/100 000 nacidos vivos. Conclusiones. Las gestantes atendidas en el HUS son predominantemente mujeres jóvenes, provenientes de áreas con difícil acceso al sistema de salud, con insuficiente atención prenatal y con bajo nivel educativo. Esta población presenta una alta razón de morbilidad materna extrema y mortalidad materna comparada con el valor de referencia nacional y se beneficiaría de intervenciones educativas o enfoques de riesgo que prioricen estos factores con el fin de prevenir desenlaces maternos adversos.

Complicaciones obstétricas y perinatales en mujeres infértiles que se embarazan / Obstetric and perinatal complications in infertile women who become pregnant

Las pacientes infértiles tienen un riesgo aumentado de resultados obstétricos y perinatales adversos que dependen de los factores de infertilidad subyacentes previos y de factores inherentes a los tratamientos recibidos para lograr el embarazo. La edad materna, las patologías previas ginecológicas, hormonales, endocrinológicas, metabólicas y anatomo funcionales son reconocidas como factores de riesgo para resultados adversos obstétricos y perinatales. Los tratamientos como la hiperestimulación ovárica y los tratamientos de reproducción asistida condicionan riesgos adicionales, especialmente por el aumento de embarazos múltiples que se generan con estas terapias. El aumento de la edad materna de pacientes tratadas por infertilidad y la necesidad creciente de tratamientos de reproducción asistida determinan probablemente, un mayor riesgo futuro de complicaciones obstétricas y perinatales. Muchos de estos factores de riesgo pueden ser modificados y manejados antes de iniciar los tratamientos con la finalidad de mejorar el pronóstico para la madre y el recién nacido. La consideración de estos factores de riesgo y sus consecuencias en el embarazo son parte esencial del consejo reproductivo que debiera recibir toda paciente que se somete a tratamientos por infertilidad.El objetivo de esta revisión es mostrar la relación existente entre las pacientes que consultan por infertilidad, los tratamientos usados y los potenciales riesgos obstétricos y perinatales cuando se produce el embarazo.

Infertile patients have an increased risk of adverse obstetric and perinatal outcomes that depend on underlying infertility factors and on those treatments recieved to become pregnant. Maternal age, hormonal, endocrinologial, metabolic and anatomic/functional gynecological diseases are widely recognized risk factors for adverse obstetric and perinatal outcomes. Infertility treatments like controlled ovarian hyperstimulation and assisted reproductive technologies add aditional risks, specially related to multiple pregnancies that are associated to. The higher maternal age of patients seeking for infertility treatment and the increasing need of assisted reproductive technologies probably determines a higher and increasing risk of obstetric and perinatal adverse outcomes. In many cases risk factors can be adequately modified and controlled before treatments are initiated thus improving maternal and neonatal prognosis. This risk factors and their consequences in pregnancy have to be strongly considered in reproductive counselling that should recieve every patient treated for infertility.The aim of this article is to show the relation between infertile patients seeking for treatment and their potential risks of obstetric and perinatal adverse outcomes when they get pregnant.
