Every year more than 20 million neonates worldwide are born with low birth weight (LBW) per year. Ninety-five percent of LBW births occur in developing countries. The aim of this study was to determine Immediate Seven Day Outcomes and Risk Factors of Low Birth Weight Neonates at Referral Hospitals in Mwanza City. MATERIALS AND METHODS This was a hospital based observational prospective cohort study of neonates with LBW whom were followed up for seven days in the neonatal wards at referral hospitals in Mwanza city. Maternal social-demographic, newborns clinical data and vitality outcomes were collected. Categorical and continuous variables were summarized and presented in tables or bar charts. Any p-value of < 0.05, at 95% confidence interval was regarded as statistically significant. RESULTS Total of 200 neonates with median age of 0.8 days at baseline were enrolled. Amongst 148 (74 %) had prolonged hospitalization; due to sickness 88 (59%), and 60 (40%) due to poor weight gain. Whereas, the remaining 42 (21%) were discharged and 10 (5%) died within seven days. Prolonged hospitalization was associated with family income (p-value= <0.001) and place of delivery (p-value = <0.001). African Journal of Health Sciences Volume 34, Issue No.4, July- August 2021 452 Neonatal death was associated with family income (p-value =0.035) and birth weight (p-value = 0.019). Early discharge associated with gestational age at first antenatal visit, family income, mode of delivery, APGAR score at one minute, time interval between delivery and admission and timing of medication initiation. CONCLUSION LBW neonates are at high risk of death and prolonged hospitalization due to sickness or due to poor weight gain. Associated factors of these outcomes were family income, place of delivery, birth weight, gestation age during first antenatal visit, mode of delivered and low APGAR score.

OBJECTIVE@#To assess the impact of confined placental mosaicism (CPM) on non-invasive prenatal testing (NIPT) and pregnancy outcomes.@*METHODS@#Copy number variation sequencing (CNV-seq) and single nucleotide polymorphism array (SNP-array) were carried out on placental specimen sampled from eight pregnancies with confirmed false-positive NIPT results. The impact of CPM on NIPT and pregnancy outcomes were analyzed based on the laboratory tests and clinical characteristics.@*RESULTS@#Five of the eight cases with false-positive NIPT results were proven to be CPM involving trisomy 9, 13, 21, 22, and X, respectively. The mosaic ratios for different placental regions have varied from 4% to 80%. Two fetuses with confirmed CPM showed fetal growth restriction (FGR) and additional ultrasound abnormalities, 1 fetus showed only FGR. The remaining two fetuses showed normal growth.@*CONCLUSION@#NIPT is highly sensitive to CPM, whilst CPM is an important cause for false-positive NIPT result. CPM may be associated with FGR. Investigation of the presence of CPM is important for both pre- and post-test genetic counseling and management of the pregnancy.

Gestational diabetes mellitus(GDM)can cause blood glucose disorders in pregnant women and result in adverse maternal-neonatal outcomes.Vitamin D(VD)can improve glucose tolerance and insulin sensitivity,and thus theoretically,VD supplementation during pregnancy could improve glycemic control as well as maternal-neonatal outcomes in GDM patients.Although studies have shown that VD deficiency is associated with poor maternal-neonatal outcomes in GDM patients,no solid conclusion has been drawn with regard to the effects of VD supplementation on these patients.Therefore,here we summarized the research progress of the effects of VD supplementation on glycemic control and adverse maternal-neonatal outcomes in GDM patients,in an effort to guide the clinical VD supplementation during pregnancy.

Objective@#Prior pulmonary tuberculosis (PTB) on chest X-ray (CXR) was commonly found in infertile patients receiving examinations before @*Method@#We conducted a retrospective cohort study of 14,254 infertile patients who had received IVF-ET at Peking University Third Hospital in 2017. Prior PTB was defined as the presence of signs suggestive of old or inactive PTB on CXR, with or without a clinical TB history. Patients who had prior PTB on CXR but had not received a clinical diagnosis and anti-TB therapy were included for analysis. Live birth, clinical pregnancy, and miscarriage rates were compared between the untreated PTB and non-PTB groups.@*Results@#The untreated PTB group had significantly lower clinical pregnancy (31.7% @*Conclusions@#Untreated PTB was associated with adverse pregnancy outcomes after IVF-ET, especially in patients with unexplained infertility, highlighting the clinical significance of PTB in this specific patient population.

Gestational hypertension and pre-eclampsia are important causes of perinatal morbidity. The objective of the present study was to determine the increase in relative risk for developing hypertensive disorders of pregnancy based on the evaluation of pregnant women between 20 and 25 weeks of gestation, and to correlate the findings at this period with the outcome of pregnancy. We conducted a prospective cohort study, with a convenience sample of 1417 patients evaluated at this gestational age, of which 1306 were contacted at childbirth. We detected an increased relative risk of 2.69 (95%CI: 1.86 to 3.89) associated with pulsatility index of the uterine arteries, a 2.8 increase (95%CI: 1.58 to 5.03) in relative risk attributed to maternal age above 35 years, a 1.68 increase (95%CI: 1.17 to 2.40) attributed to parity greater than or equal to 3, and a 5.35 increase (95%CI: 4.18 to 6.85) attributed to chronic hypertension and obesity, with a progressive increase in relative risk according to the degree of overweight, i.e., grades 1, 2, 3, and morbid obesity (2.58, 3.06, 5.84, and 7.28, respectively).

High proportions of placental lymphocytes expressing DX5+/CD25+/FOXP3+/CD45+/CD4+ are beneficial to maintain immune tolerance and improve pregnancy outcomes. This study aimed to compare and evaluate the therapeutic effects of aspirin, vitamin D3 (VitD3), and progesterone on the autoimmune recurrent spontaneous abortion (RSA) model. The autoimmune RSA mouse model was constructed, and the embryo loss rate was calculated for each group. Then, primary mouse placental lymphocytes were isolated, and the expression of DX5+/CD25+/FOXP3+/CD45+/CD4+ was detected through flow cytometry. The serum levels of anti-cardiolipin antibody (ACA), β2-GP1, CXCL6, IFN-γ, and IL-6 were measured by ELISA to evaluate the proportion of Th1 and Th2 cells. Autoimmune RSA significantly increased the embryo loss rate, which was improved by aspirin, VitD3, and progesterone treatment, and progesterone treatment had the best effect among the three treatments. The positive expression of DX5+/CD25+/FOXP3+/CD45+/CD4+ in the VitD3 and progesterone groups was significantly higher than that in the autoimmune RSA group, and the expression was highest in the progesterone treatment group. In the plasma of autoimmune RSA mice, the ACA, β2-GP1, CXCL6, and IFN-γ levels were significantly higher and the IL-6 level was lower than the levels in control mice. All these changes could be reversed by aspirin and progesterone treatment. In conclusion, aspirin, VitD3 and progesterone treatment improved pregnancy outcomes in autoimmune RSA mice by regulating the Th1/Th2 balance and cytokines, and progesterone had the best effect of the three treatments.

ABSTRACT Introduction: twin-to-twin transfusion syndrome (TTTS), defined by combination of polyhydramnios-oligohydramnios, is the most prevalent (5%-35%) of the abnormalities due to placental vascular anastomoses and the most lethal (80%-100% mortality) if untreated. Fetoscopic laser ablation of abnormal vasculature using the Solomon technique is the gold standard approach. It consists of interrupting the intertwin blood flow. Objectives: to present our initial experience at the Fetal Surgery Service of the Hospital de Clinicas of the Federal University of Parana (HC-UFPR) and to compare our results with those reported in the literature. Methods: we conducted a retrospective analysis of pregnancies who had undergone laser ablation, assessing data on Quintero's staging, gestational age at diagnosis and at the time of the procedure, placental position, immediate post-procedure survival, and survival after the neonatal period. We then compared these data with the most recent data available in the literature. Results: we analyzed ten TTTS cases. The diagnosis was performed before the 26th week of pregnancy (median 20.8 weeks) and treatment occurred in a median of 9.5 days later. The distribution by the Quintero's staging was of three cases in stage II, five in stage III, and two in stage IV. In 50% of the gestations, at least one of the fetuses survived through the neonatal period. Conclusion: the treatment of TTTS in the HC-UFPR had a positive impact in the survival of the affected fetuses, although the results were worse than the ones reported in the literature, probably due to the delay in referencing the patients to our service, leading to a prolonged interval between diagnosis and treatment.

RESUMO Introdução: a síndrome de transfusão feto-fetal (STFF), definida pela combinação polidrâmnio-oligohidrâmnio, é a mais prevalente (5 a 35%) das anormalidades associadas às anastomoses vasculares placentárias e tem a maior letalidade (80 a 100%) se não tratada. A ablação a laser destes vasos por via fetoscópica com a técnica de Solomon é o tratamento de escolha atual para a interrupção das anastomoses vasculares. Objetivo: apresentar a experiência inicial do Serviço de Cirurgia Fetal do Hospital de Clínicas da Universidade Federal do Paraná (HC-UFPR) e comparar nossos resultados com os da literatura. Métodos: foram revisados os prontuários de todas as pacientes submetidas ao procedimento de ablação a laser, sendo analisados os dados referentes ao estadiamento de Quintero, à idade gestacional ao diagnóstico e ao procedimento, à posição placentária, à sobrevida imediata pós-procedimento e sobrevida após o período neonatal. Os dados foram então comparados com os mais recentes disponíveis na literatura. Resultados: dez casos de STFF foram analisados. Todos diagnosticados antes da 26a semana (mediana 20,79) e o intervalo diagnóstico-tratamento teve mediana de 9,5 dias. A distribuição pelo estadiamento de Quintero foi: três casos no estádio II, cinco casos no III e dois casos no IV. Em 50% das gestações pelo menos um dos fetos sobreviveu ao período neonatal. Conclusão: o tratamento da STFF no HC-UFPR impactou positivamente a sobrevida dos fetos acometidos. Entretanto, nossos resultados estão aquém dos reportados na literatura, possivelmente pelo demora no referenciamento das pacientes, com intervalo aumentado entre diagnóstico e tratamento.

INTRODUCCIÓN: El SARS-CoV-2 tiene una rápida expansión por todo el mundo, sin embargo, su capacidad para causar enfermedad grave no es homogénea según sexo y edad. OBJETIVO: Determinar las características perinatales, morbilidad, mortalidad y resultados serológicos en neonatos de gestantes seropositivas para SARS-CoV-2. MÉTODOS: Estudio transversal, descriptivo y retrospectivo. Participaron todos los neonatos cuyas madres presentaron resultado seropositivo para SARS-CoV-2 antes del parto, entre el 15 de abril y 10 de mayo de 2020 en el Instituto Nacional Materno Perinatal de Perú. Se recogió información materna y neonatal a partir de sus historias clínicas. En el análisis se usó estadística descriptiva y prueba exacta de Fisher. RESULTADOS: Se identificaron 114 neonatos, el 36,8% presentó inmunoglobulinas M y G positivas para SARS-CoV-2; el 7% inmunoglobulinas G y 56,2% fue no reactivo. Las complicaciones obstétricas más frecuentes fueron rotura prematura de membranas (14,9%) y parto pretérmino (8,8%). El 8,8% de los neonatos presentaron un puntaje Apgar al minuto menor o igual a seis, y de ellos solo uno persistió a los cinco minutos; tres neonatos fallecieron. Se evidenció asociación entre el tipo de inmunoglobulina materna y la serología de su recién nacido (p < 0,05). No se observó asociación entre resultados perinatales y el tipo de inmunoglobulinas materna (p > 0,05), ni con los resultados serológicos en el neonato para SARS-CoV-2 (p > 0,05). CONCLUSIÓN: El 43,9% de neonatos de madre seropositiva a SARS-CoV-2 tuvo un resultado serológico positivo, siendo más frecuente de tipo Inmunoglobulinas M e Inmunoglobulinas G. El 10,5% de los neonatos presentó alguna morbilidad, siendo más frecuente prematuridad y bajo peso al nacer y el 2,6% falleció. Los resultados perinatales no estuvieron asociadas al tipo de inmunoglobulina de las madres seropositivas a SARS-CoV-2. De igual modo, los resultados perinatales no estuvieron asociados a los resultados serológicos en el neonato.

INTRODUCTION: SARS-CoV-2 has spread rapidly throughout the world. However, its ability to cause severe disease is not homogeneous according to sex and the different age groups. OBJECTIVE: To determine perinatal characteristics, morbidity, mortality, and serological results in neonates from seropositive pregnant women to SARS-CoV-2. METHODS: We did a retrospective, descriptive, cross-sectional study. We included all newborns from positive pregnant women to SARS-CoV-2, between April 15 and May 10, 2020, who delivered in the National Perinatal Maternal Institute of Peru. The study extracted maternal and neonatal variables collected from the medical charts. The data were analyzed using descriptive statistics and Fischer's exact test. RESULTS: One hundred fourteen neonates were identified, 36.8% IgM/IgG positive for SARS-CoV-2, 7% IgG, and 56.2% had negative serology. The obstetric complications were premature rupture of membranes (14.9%) and preterm birth (8,8%). 8.8% of newborns had an Apgar score of less than or equal to six minutes, and of those, only one persisted after five minutes; three newborns died. There was an association between the type of maternal immunoglobulin and the serology of the newborn (p < 0.05). No association was observed between perinatal results and maternal immunoglobulin type (p > 0.05) or serological results in the newborn for SARS-CoV-2 (p > 0.05). CONCLUSION: 43.9% of seropositive mothers' neonates to SARS-CoV-2 had a positive serological result, more frequently type IgM/IgG. 10.5% of the neonates had some morbidity, more frequent prematurity, low birth weight, and 2.6% died. Perinatal results were not associated with the type of immunoglobulin of mothers seropositive to SARS-CoV-2; similarly, perinatal results were not associated with serological results in the newborn.

INTRODUCCIÓN Y OBJETIVOS: El Síndrome Respiratorio Agudo Grave Coronavirus 2 (SARSCoV-2) es una enfermedad altamente contagiosa y que puede ser transmitida por pacientes asintomáticos. Por esto surge el interés de poder determinar la prevalencia de la infección por SARS-Cov-2 en pacientes embarazadas que ingresan para interrupción de la gestación. MÉTODOS: Se realizó un análisis descriptivo, retrospectivo en el Servicio de Obstetricia y Ginecología de Hospital de Carabineros de Chile entre el 15 de mayo y el 30 junio del 2020. Se incluyeron todas las mujeres embarazadas que ingresaron para interrupción de la gestación, a las que se les realizó el examen PCR SARS-CoV-2; y una encuesta de signos y síntomas sugerentes de la enfermedad. RESULTADOS: Se realizaron 73 interrupciones de la gestación, con toma de PCR a 72 mujeres; de estas pacientes 65 (90.3%) fueron negativas, 5 (6.9%) positivas y 2 (2.8%) indeterminadas; los resultados indeterminados fueron considerados como positivos, por lo que la prevalencia de positividad fue de 9,5%. De estas pacientes, sólo 1 de ellas tenía síntomas sugerentes de la enfermedad, todas las demás (6) eran pacientes asintomáticas, y se mantuvieron así durante toda la hospitalización. CONCLUSIÓN: La realización del examen PCR para SARS-CoV-2 a todas las embarazadas que ingresan a un servicio de Ginecología y Obstetricia ayuda a identificar a las pacientes asintomáticas contagiadas con el virus. Ya que la consulta por presencia de signos y síntomas no permite identificar los casos positivos, es necesario considerar la realización de este examen en los protocolos de ingreso hospitalario a lo largo de nuestro país.

INTRODUCTION AND OBJECTIVES: Severe Acute Respiratory Syndrome Coronavirus (SARSCoV-2) is a highly contagious disease that can be transmitted by asymptomatic patients. Therefore, is of interest to determine the prevalence of SARS-Cov-2 infection in pregnant patients entering for interruption. METHODS: A descriptive, retrospective analysis was performed in the Obstetrics and Gynecology Service of the Hospital de Carabineros de Chile between May 15 and June 30, 2020. Pregnant women who entered for interruption of their pregnancy and who were given the SARS-CoV-2 PCR exam were included. A survey of signs and symptoms suggestive of the disease was applied. RESULTS: There were 73 pregnancy interruptions, 72 of them were tested by SARS-CoV-2 PCR exam. Among these patients, 65 (90.3%) resulted negative, 5 (6.9%), were positive and 2 (2.8%) were indeterminate; indeterminate results were considered positive, so the prevalence of positivity was 9.5%. Of these patients only 1 had symptoms suggestive of the disease, all the others (6) were asymptomatic, and remained so throughout the hospitalization. CONCLUSION: Conducting the PCR test for SARS-CoV-2 for all pregnant women entering a Gynecology and Obstetrics service helps to identify asymptomatic patients infected with the virus. As a survey of signs and symptoms cannot identify positive patiens, it is necessary to consider conducting universal screeing in hospital admission protocols throughout our country.

INTRODUCCIÓN Y OBJETIVOS: COVID-19 es una patología producida por el virus RNA SARS-CoV-2, declarada pandemia por la OMS en marzo de 2020. La literatura mundial describe mayor incidencia de parto prematuro y cesáreas en pacientes infectadas por COVID-19 principalmente de origen iatrogénico, sin embargo, existen escasos datos del pronóstico del embarazo al decidir diferir el parto hasta después del período infeccioso del virus. Este trabajo reporta un grupo de embarazadas diagnosticadas con COVID-19 en tercer trimestre donde se decidió no interrumpir el embarazo y diferir su parto hasta recuperación de la patología. MÉTODOS: Estudio observacional retrospectivo que analiza resultados materno-perinatales en 9 casos de mujeres infectadas por COVID, diagnosticadas posterior a las 33 semanas y cuyo parto se verificó después de recuperadas del COVID. RESULTADOS: Se observó un 77% de pacientes sintomáticas, 77% requirieron hospitalización, 33% por COVID, todas ingresaron a unidad de paciente crítico, sólo una requirió ventilación mecánica no invasiva. Dos cursaron con cetoacidosis normo-glicémica y dos con neumonía por COVID-19. Un 88% resultó en parto de término, sólo una paciente tuvo parto prematuro de causa obstétrica. La vía de parto fue un 67% vaginal y 33% por cesárea, todas por indicación obstétrica. La latencia al parto promedio fue de 17.3 días. Los puntajes de Apgar fueron todos mayor a 7 al minuto y 5 minutos. CONCLUSIÓN: Los resultados de esta serie sugieren que, en casos seleccionados, los partos posteriores al período infeccioso del COVID se asocian a buenos resultados materno-perinatales, sin embargo, resulta importante aumentar la casuística.

INTRODUCTION AND OBJECTIVES: COVID-19 is a pathology produced by the RNA virus SARS-CoV-2, declared a pandemic by the WHO in March of 2020. The world literature describes more preterm birth and caesarean section in pregnant women infected by COVID-19, principally by medical indication, but it has not been described in depth what happens when we differ delivery after the infectious period. This report reviews a subgroup of patients who were diagnosed with COVID-19 in the third trimester and decided to differ birth until they recovered from the disease. METHODS: Retrospective observational study that analyzes maternal and perinatal outcome of 9 women who were diagnosed with COVID-19 after the 33 weeks of pregnancy, decided to differ delivery and had their birth recovered from the disease. RESULTS: We observed 77% of patients symptomatic, 77% required hospitalization, 33% because of COVID, all admited to critical patient care, only one required non invasive mechanical ventilation. 2 patients suffered normoglycemic ketoacidosis, 2 had COVID-19 pneumonia. An 88% resulted in term birth, only 1 was prematurely interrupted by obstetric cause. 66% patients had vaginal delivery and 33.3% caesarean section, all by obstetric cause. The average latency to birth was 17.3 days. Apgar scores were all more than 7 at minute 1 and 5. CONCLUSION: The results of this series suggest that in selected cases where the clinical characteristics allow it, to differ interruption of pregnancy until after the infectious period can associate to good outcomes of maternal and neonatal morbimortality, however, it's fundamental to continue research.

INTRODUCCIÖN Y OBJETIVOS: Describir la experiencia de los partos en gestantes con diagnóstico confirmado de COVID 19 mediante RT-PCR asintomáticas o con sintomatología leve y aquellas sin la enfermedad, y determinar la tasa de éxito de parto vaginal en inducción de trabajo de parto. MÉTODOS: Análisis retrospectivo de pacientes que tuvieron su parto entre 15 de Abril y 03 de Julio del 2020 en el Hospital San Juan de Dios. Se incluyeron las pacientes inducidas con Dinoprostona, Oxitocina o ambas de manera secuencial y se dividieron según estatus COVID 19 mediante RT-PCR al ingreso. Se caracterizó demográficamente el grupo de pacientes positivas y se determinaron los datos de ambos grupos en relación a la necesidad de inducción de trabajo de parto y su éxito para parto vaginal. RESULTADOS: De un total de 657 nacimientos, hubo un 9.7% (n=64) de pacientes con COVID 19, de las cuales un 23.4% (n=15) requirió inducción de trabajo de parto, con una tasa de éxito para parto vaginal de un 66.7% (n=10). De estas pacientes, un 50% recibió Oxitocina, un 40% Dinosprostona y un 10% ambos medicamentos de forma secuencial. En las pacientes negativas, hubo un total de 568 nacimientos, con un 29.8% (n=169) de usuarias que requirieron inducción. La tasa de éxito para parto vaginal en este grupo fue de 72.2% (n=122), utilizando un 50% Oxitocina; un 27% Dinoprostona; un 14.8% ambas; y un 8.2% Balón de Cook. CONCLUSIONES: Sabemos que los resultados de este estudio están limitados por el bajo número de pacientes incluidas, sin embargo, podemos observar que, en nuestra experiencia con las pacientes que arrojaron PCR SARS-CoV-2 positivas, asintomáticas o con enfermedad leve, se logró realizar la inducción de trabajo de parto según protocolos habituales, obteniendo porcentajes de éxito para partos vaginales, similares a las pacientes sin la enfermedad.

INTRODUCTION AND OBJECTIVES: Describe the experience of deliveries in pregnant women with a confirmed diagnosis of COVID 19 by asymptomatic RT-PCR or with mild symptoms and those without the disease, and determine the success rate of vaginal delivery in the induction of labor. METHODS: Retrospective study of patients who had their delivery between 15th April and 03rd of July, 2020 in the San Juan de Dios Hospital. Patients induced with Dinoprostone, Oxytocin or both sequentially were included, and were divided according to COVID 19 status by RT-PCR on their admission process. The group of positive patients was demographically characterized and the data of both groups was determined in relation to the need for labor induction and its success for vaginal delivery. RESULTS: Of a total of 657 births, there were 9.7% (n = 64) of patients with COVID 19, of which 23.4% (n = 15) required labor induction, with a success rate for vaginal delivery of 66.7% (n = 10). Of these patients, 50% received Oxytocin, 40% Dinosprostone and 10% both drugs sequentially. In the negative patients, there were a total of 568 births, with 29.8% (n = 169) of users requiring labor induction. The success rate for vaginal delivery in this group was 72.2% (n = 122); 50% using Oxytocin; 27% Dinoprostone; 14.8% using both; and 8.2% using Cook's Catheter. CONCLUSIONS: We know that the results of this study are limited by the low number of patients included, however, in our experience, we can observe that, in patients with SARS-CoV-2 PCR positive, asymptomatic or with mild disease, it was possible to perform induction of labor according to standard protocols, achieving success rates for vaginal deliveries, similar to patients without the disease.

INTRODUCCIÓN: En comparación con pandemias anteriores por otros virus, el SARS-CoV-2 ha afectado a la población obstétrica en menor número, por lo que registrar la historia clínica en pacientes con COVID 19 de nuestra población se hacía imperativo. METODOLOGÍA: Se realizó un estudio descriptivo transversal no analítico en la maternidad del Hospital El Pino. Se realizaron test PCR para SARS-CoV-2 entre abril y junio del 2020 a todas las usuarias con: (1) síntomas sugerentes de COVID 19, (2) antecedente de contacto estrecho o (3) que requiera hospitalización independientemente del motivo. En ellas se analizaron variables demográficas, evolución clínica y se estimaron "outcomes" obstétricos. RESULTADOS: Se tomaron 409 PCR y de éstas 365 en población obstétrica alcanzando en ella una incidencia acumulada de positividad de 19.7%. El 55.6% (40 pacientes) asintomáticas, 4.2% (9 pacientes) contacto estrecho y 40.3% (29 pacientes) sintomáticas. De estas pacientes la mayoría resulto ser de nacionalidad chilena (79.2%) con una prevalencia de HTA y DM tipo 1 o 2 entre el 8-10%. La media de la edad gestacional en la cual se realizó el diagnóstico fue en el 3er trimestre y la del momento del parto fue de 37.1 semanas (+/-3.9). Los síntomas más comunes presentados fueron tos, cefalea y mialgias; sin embargo, 7 requirieron ingreso a unidad de cuidados intensivos. En el seguimiento de usuarias asintomáticas 6,9% y 2,8% presentaron síntomas al día 7 y 14 respectivamente. CONCLUSIONES: La pandemia SARS-CoV-2 ha afectado la población obstetrica de igual manera, presentandose en su mayoría de forma asintomática, destacando la importancia del screening universal a la hora de hospitalizar nuestras usuarias y evitar transmisión intrahospitalaria.

INTRODUCTION: Compared to previous pandemics caused by other viruses, SARS-CoV-2 has affected the obstetric population in a smaller number, thus recording the medical history in patients with COVID 19 in our population became imperative. METHODOLOGY: A non-analytical, cross-sectional descriptive study was carried out in the maternity section of Hospital El Pino. PCR tests for SARS-CoV-2 were performed between April and June 2020 to all patients with: (1) symptoms suggestive of COVID 19, (2) a history of close contact or (3) requiring hospitalization regardless of motive. In them, demographic variables, clinical evolution were analysed and obstetric outcomes were estimated. RESULTS: 409 PCR were taken, raising a cumulative incidence of positivity of 19.7%. 55.6% (40 patients) were asymptomatic, 4.2% (9 patients) were close contact and 40.3% (29 patients) symptomatic. Within these patients, the majority turned out to be Chilean (79.2%) with a prevalence of HT and DM type 1 or 2 between 8-10%. The average of the gestational age at which the diagnosis was made was in the 3rd trimester and that of the moment of delivery was 37.1 weeks (+/- 3.9). The most common symptoms presented were cough, headache and myalgia, however, 7 patients required admission to the intensive care unit. In the monitoring stage of asyntomatic patients, 6.9% and 2.8% had symptoms on day 7 and 14 respectively. CONCLUSIONS: The SARS-CoV-2 pandemic has affected the obstetric population with no difference, with the majority presenting asymptomatic, fact which highlights the importance of universal screening when hospitalizing our users and avoiding intra-hospital transmission.

INTRODUCCIÓN: En Chile, los efectos maternos y perinatales de la pandemia por SARS-CoV-2 son aún desconocidos. GESTACOVID es un estudio multicéntrico que incluye embarazadas y puérperas hasta el día 42 con COVID-19. El objetivo de este estudio es presentar un informe preliminar, describiendo el impacto de la enfermedad en las embarazadas, factores de riesgo asociados y resultados perinatales. MÉTODOS: Estudio de cohorte descriptivo que incluye 661 pacientes enroladas entre el 7 de marzo y el 6 de julio de 2020, en 23 centros hospitalarios del país. Se analizaron variables demográficas, comorbilidades, características clínicas y del diagnóstico de COVID-19 y resultado materno y perinatal. RESULTADOS: Las pacientes hospitalizadas por COVID-19 tuvieron mayor prevalencia de hipertensión arterial crónica [10% vs 3%; OR=3,1 (1,5-6,79); p=0,003] y de diabetes tipo 1 y 2 [7% vs 2%; OR=3,2 (1,3-7,7); p=0,009] que las pacientes manejadas ambulatoriamente. Un IMC >40 kg/mt2 se asoció con un riesgo dos veces mayor de requerir manejo hospitalizado [OR=2,4 (1,2 - 4,6); p=0,009]. Aproximadamente la mitad de las pacientes (54%) tuvo un parto por cesárea, y un 8% de las interrupciones del embarazo fueron por COVID-19. Hasta la fecha de esta publicación, 38% de las pacientes continuaban embarazadas. Hubo 21 PCR positivas en 316 neonatos (6,6%), la mayoría (17/21) en pacientes diagnosticadas por cribado universal. CONCLUSIONES: Las embarazadas con COVID-19 y comorbilidades como diabetes, hipertensión crónica y obesidad mórbida deben ser manejadas atentamente y deberán ser objeto de mayor investigación. La tasa de transmisión vertical requiere una mayor evaluación para diferenciar el mecanismo y tipo de infección involucrada.

INTRODUCTION: In Chile, effects of the SARS-CoV-2 infection in pregnant women are unknown. GESTACOVID is a multicenter collaborative study including pregnant women and those in the postpartum period (until 42 days) who have had COVID-19. The purpose of this study is to report our preliminary results describing the clinical impact of COVID-19 in pregnant women, the associated risk factors and perinatal results. METHODS: Descriptive cohort study including 661 patients between April 7th and July 6th, 2020, in 23 hospitals. Demographical, comorbidities, clinical and diagnostic characteristics of COVID-19 disease and maternal and perinatal outcomes were analyzed. RESULTS: Pregnant women with COVID-19 admitted to the hospital were more likely to have chronic hypertension [10% vs 3%; OR=3.1 (1.5-6.79); p=0,003] and diabetes type 1 and 2 [7% vs 2%; OR=3.2 (1.3-7.7); p=0.009] than those with outpatient management. A body mass index of >40 kg/mt2 was associated with two-fold higher risk of hospitalization [OR=2.4 (1.2-4.6); p=0.009]. Almost half of patients (54%) were delivered by cesarean section, and 8% of the medically indicated deliveries were due to COVID-19. So far, 38% of the patients are still pregnant. Among 316 newborns, there were 21 positive PCR tests (6.6%), mostly from asymptomatic mothers undergoing universal screening. CONCLUSIONS: Pregnant women with COVID-19 and comorbidities such as diabetes, chronic hypertension and morbid obesity need a close follow up and should be a matter for further research. Vertical transmission of COVID-19 should be thoroughly studied to define the mechanisms and type of infection involved.

Introducción: La Pandemia ocasionada por el nuevo coronavirus SARS-CoV-2 ha tenido repercusión también en nuestra región. Las embarazadas constituyen un grupo especial dentro de la población. Casos Clínicos: Se reportan 6 casos de pacientes embarazadas interrumpidas en el Hospital Carlos Van Buren hasta Julio de 2020 con PCR positivo para SARS-CoV-2, donde una cursó con neumonía grave, 3 con síntomas leves y 2 asintomáticas. El 100% fue interrumpido por cesárea. 50% de los recién nacidos fue ingresado a neonatología. En ninguno se evidenció transmisión vertical. Conclusiones: La infección por SARS-CoV-2 no constituye una indicación inmediata por cesárea, sin embargo, se ha visto un gran aumento. No se ha observado clara evidencia de transmisión vertical, pero faltan estudios de mejor calidad.

Introduction: The pandemic caused by the new SARS-CoV-2 coronavirus has also had repercussions in our region. Among others, pregnant women constitute a special group within the affected population. Clinical Cases: There are 6 reported cases of pregnant patients interrupted in Hospital Carlos Van Buren are reported until July 2020 with a positive PCR for SARS-CoV-2, where one was treated with severe pneumonia, 3 with mild symptoms and 2 were asymptomatic. The 100% was interrupted by caesarean section. 50% of the newborns were admitted to neonatology. Vertical transmission was not evident in any of them. Conclusions: SARS-CoV-2 infection is not an immediate indication for cesarean section. However, a considerable increase in the tendency for the surgery has been observed. No clear evidence of vertical transmission has been observed, but better quality studies are needed.

INTRODUCCIÓN: El diagnóstico prenatal de anomalías congénitas tiene como objetivo ofrecer consejería apropiada, identificar aquellas patologías que se benefician de terapia fetal y coordinar la derivación de estas pacientes a centros terciarios para un óptimo manejo perinatal. Para el diagnóstico y manejo de las anomalías congénitas en el Hospital Dr. Sótero Del Río contamos con un equipo multidisciplinario. El objetivo de este estudio es describir nuestra experiencia como centro de referencia en Santiago de Chile en relación al diagnostico prenatal de malformaciones congénitas, estudio genético prenatal y resultados perinatales. MÉTODOS: Estudio retrospectivo y descriptivo. Se incluyó a las pacientes registradas en las bases de datos ecográficas entre 2010 y 2019 del Hospital Dr. Sotero del Rio. Se revisaron fichas clínicas para evaluación y seguimiento postnatal. RESULTADOS: Se evaluaron 404 pacientes con sospecha de malformaciones congénitas o marcadores de aneuploidías. La edad gestacional media de la evaluación fue 29 semanas (14-38 semanas). La mediana de la edad gestacional al parto fue 37.6 semanas (20-41 semanas). Se obtuvo un 78% de recién nacidos vivos, 12% óbitos fetales y 10% mortineonatos. Las malformaciones más frecuentes fueron cardiovasculares, sistema nervioso central, hidrops, extremidades, abdomen y genitourinario. Se realizo el estudio genético en 232 pacientes; 61% resultado normal, 12.5% trisomía 21, 8% trisomía 18, 4% trisomía 13, 4% XO, 4% otras. Se analizaron las pacientes que se acogieron a la ley de interrupción voluntaria del embarazo. CONCLUSIÓN: Destacamos la importancia de derivación a centros de referencia de pacientes con sospecha de malformaciones congénitas para un adecuado diagnostico prenatal, ofrecer un manejo con equipo multidisciplinario y así mejorar los resultados neonatales.

INTRODUCTION: The objectives of prenatal diagnosis of fetal malformations are to offer the patient and her family the proper counseling, identify those conditions that benefits of prenatal therapy and to coordinate the referral to tertiary centers to improve neonatal survival. Our hospital counts with a multidisciplinary team who evaluate the patients together. The objective of this study is to describe our experience as a referral center in prenatal diagnosis, management and neonatal outcomes in Santiago de Chile. METHODS: Retrospective and descriptive study. Patients registered in our prenatal diagnosis database between September 2010 and July 2019 were included. Clinical files were reviewed for neonatal outcomes. OUTCOMES: 404 patients with congenital malformations or aneuploidy markers were evaluated. The average gestational age of the evaluation was 29 weeks. Median gestational age to delivery was 37 weeks plus 6 days. 78% of livebirth, 12% fetal demise and 10% of neonatal death were obtained. The most frequent fetal malformations were cardiovascular, central nervous system, fetal hydrops, extremities, abdominal wall defects and urinary system. Fetal karyotype was performed in 232 patients; 61% normal karyotype, 12.5% trisomy 21, 8% trisomy 18, 4% trisomy 13, 4% monosomy X, 4% others. We also analyze the patients who agreed to termination of pregnancy according to Chilean legislation. CONCLUSION: We highlight the importance of referral of patients with suspected fetal malformations to tertiary centers for an adequate evaluation by a multidisciplinary team of specialists, to improve the survival and neonatal outcome.

La utilización de técnicas de reproducción asistida (TRA) ha aumentado en todo el mundo, incluyendo procedimientos como la donación de gametos, la subrogación y el diagnóstico genético preimplantacional. Creciente evidencia confirma que los embarazos de pacientes sometidas a estos tratamientos tienen un mayor riesgo de complicaciones perinatales. No queda claro si la causa de estos hallazgos se debe a la infertilidad subyacente o los tratamientos en sí. Esta revisión tiene como objetivo resumir la evidencia actual acerca de los efectos sobre los resultados maternos y perinatales tanto de los diferentes procedimientos propios de la fecundación in vitro como de algunos tipos de TRA especiales.

The use of assisted reproduction techniques (ART) has increased worldwide, including procedures such as gamete donation, subrogation and preimplantation genetic diagnosis. Growing evidence confirms that pregnancies following these treatments have an increased risk of adverse perinatal outcomes. It is not clear whether the cause of these findings is due to the underlying infertility or the treatments themselves. This review aims to summarize the current evidence regarding the effects of both the different ART procedures and some special types of ART on maternal and perinatal outcomes.

This project was designedto explore the effects of ritodrine hydrochloride combined with magnesium sulfate in the prevention of preterm delivery of patients with threatened premature birth. 128 cases of threatened premature birth were randomly divided into two groups according to the number table method. The control group was treated with magnesium sulfate, while the study group was treated with ritodrine hydrochloride combined with magnesium sulfate. The data (p > 0.05) was analyzed using SPSS 18.0 and was subjected to Chi-square and t-test. The onset time and prolonged gestation time of the study group were shorter than those of the control group (p < 0.05). There was no difference in the incidence of myocardial ischemia between the study group and the control group (p > 0.05). The heart rate per minute of the study group was higher than that of the control group (p < 0.05). There was no difference in blood pressure between the study group and the control group. Nevertheless, the neurological function, pregnancy outcome, and neonatal status of the group were better than those of the control group (p < 0.05).(AU)

Este projeto foi desenvolvido para explorar os efeitos do cloridrato de ritodrina combinado com sulfato de magnésio na prevenção do parto prematuro de pacientes com risco de nascimento prematuro. 128 casos de nascimento prematuro ameaçado foram divididos aleatoriamente em dois grupos, de acordo com o método da tabela numérica. O grupo de controle foi tratado com sulfato de magnésio, enquanto o grupo de estudo foi tratado com cloridrato de ritodrina combinado com sulfato de magnésio. Os dados (p > 0,05) foram analisados pelo SPSS 18.0 e submetidos ao teste do qui-quadrado e ao teste t. O tempo de início e o tempo prolongado de gestação do grupo de estudo foram menores que os do grupo de controle (p < 0,05). Não houve diferença na incidência de isquemia miocárdica entre o grupo de estudo e o grupo de controle (p > 0,05). A frequência cardíaca por minuto do grupo de estudo foi superior à do grupo controle (p < 0,05). Não houve diferença na pressão arterial entre o grupo de estudo e o grupo de controle. No entanto, a função neurológica, o resultado da gravidez e o status neonatal do grupo foram melhores do que os do grupo de controle (p < 0,05).(AU)
