RESUMEN
BACKGROUND: Neonatal surgery is one of the most specialized and demanding areas of pediatric surgery due to the specific anatomical and physiological characteristics of this vulnerable group of patients. This study aimed to present the experience of 10 years of neonatal surgical management in a secondary care perinatal hospital in Mexico. METHODS: We conducted a descriptive, observational, cross-sectional, and retrospective study in a perinatal hospital in Toluca, Mexico, from August 01, 2012, to July 31, 2022. We included patients who underwent surgery within the hospital facilities by the Service of Pediatric Surgery. We studied demographic, clinical, and surgical variables and performed descriptive and inferential statistics. RESULTS: A total of 551 patients underwent surgery during this period with a prevalence of 0.5%. The number of patients operated in the neonatal period was 497 (90.1%). Forty-eight pathologies were recorded, with a predominance of congenital malformations in 64.6% and prenatal diagnosis in 40.5% of cases. The survival rate was 89.7%. In the bivariate analysis of mortality, we found an inverse relationship between weight and gestational age (p < 0.05). CONCLUSION: Although not a local or national reference center, the hospital where the study was conducted treats various congenital and acquired diseases, with a mortality rate that tends to decrease, close to the international average, and lower than national reports.
INTRODUCCIÓN: La cirugía pediátrica en la atención del recién nacido es una de las ramas más especializadas y demandantes debido a las particulares características anatómicas y fisiológicas de este vulnerable grupo de pacientes. El objetivo de este estudio fue presentar la experiencia de diez años de manejo quirúrgico neonatal en un hospital perinatal de segundo nivel de atención en México. MÉTODOS: Se llevó a cabo un estudio descriptivo, observacional, transversal y retrospectivo, en un hospital perinatal de Toluca, México, del 01 de agosto de 2012 al 31 de julio de 2022. Se incluyeron los pacientes sometidos a cirugía dentro de las instalaciones del hospital por parte del servicio de Cirugía Pediátrica. Se estudiaron variables demográficas, clínicas y quirúrgicas, realizando estadística descriptiva e inferencial. RESULTADOS: Un total de 551 pacientes fueron intervenidos quirúrgicamente en este periodo, con una prevalencia de 0.5%. La cantidad de pacientes operados en el periodo neonatal fue de 497 (90.1%). Se presentaron 48 patologías con predominio de las congénitas en el 64.6% y diagnóstico prenatal en el 40.5% de los casos. La supervivencia de los pacientes fue del 89.7%. En el análisis bivariado de mortalidad se encontró una relación inversa con el peso y edad gestacional (p < 0.05). CONCLUSIONES: En el hospital donde se realizó el estudio, a pesar de no ser un centro de referencia local o nacional, se atiende una amplia diversidad de padecimientos congénitos y adquiridos, con una mortalidad con tendencia a disminuir cercana a la media internacional y menor que los reportes nacionales.

RESUMEN
COVID-19 is a severe respiratory disease threatening pregnant women, which increases the possibility of adverse pregnancy outcomes. Several recent studies have demonstrated the ability of SARS-CoV-2 to infect the mother enterocytes, disturbing the gut microbiota diversity. The aim of this study was to characterize the entero-mammary microbiota of women in the presence of the virus during delivery. Fifty mother−neonate pairs were included in a transversal descriptive work. The presence of SARS-CoV-2 RNA was detected in nasopharyngeal, mother rectal swabs (MRS) and neonate rectal swabs (NRS) collected from the pairs, and human colostrum (HC) samples collected from mothers. The microbiota diversity was characterized by high-throughput DNA sequencing of V3-16S rRNA gene libraries prepared from HC, MRS, and NRS. Data were analyzed with QIIME2 and R. Our results indicate that several bacterial taxa are highly abundant in MRS positive for SARS-CoV-2 RNA. These bacteria mostly belong to the Firmicutes phylum; for instance, the families Bifidobacteriaceae, Oscillospiraceae, and Microbacteriaceae have been previously associated with anti-inflammatory effects, which could explain the capability of women to overcome the infection. All samples, both positive and negative for SARS-CoV-2, featured a high abundance of the Firmicutes phylum. Further data analysis showed that nearly 20% of the bacterial diversity found in HC was also identified in MRS. Spearman correlation analysis highlighted that some genera of the Proteobacteria and Actinobacteria phyla were negatively correlated with MRS and NRS (p < 0.005). This study provides new insights into the gut microbiota of pregnant women and their potential association with a better outcome during SARS-CoV-2 infection.

Although COVID-19 in pregnant women and their neonates has been demonstrated, there is not enough evidence about how this vertical transmission occurs. This report describes a SARS-CoV-2 infection in a 21-year-old mother-daughter duo at the time of birth, focusing on the viral RNA detection in the stool of both and the human breast milk.
