Cesarean section prevalence based on prenatal care provider, location, and wealth index: A comparative analysis in peru's healthcare systems.

BACKGROUND: Cesarean section rates are increasing and surpassing WHO guidelines. While sometimes necessary, excessive use poses risks and additional costs to pregnant women and healthcare systems. AIM: To evaluate the prevalence of cesarean section according to healthcare professionals, facility location, and the wealth index of pregnant women in each Peruvian healthcare system. METHODS: A cross-sectional study analyzed 20,870 records of women aged 12 to 49 from the Demographic and Family Health Survey (ENDES). The evaluated healthcare systems were the Ministry of Health, Social Health Insurance, Armed Forces and National Police, and private institutions. FINDINGS: The highest cesarean section prevalence was observed in women receiving prenatal care in private hospitals or clinics (69.13%) and Social Health Insurance hospitals (51.54%). Urban settings, "richest" wealth index, and medical professional involvement increased the probability of cesarean sections. Conversely, the probability of cesarean section was reduced in Ministry of Health facilities when pregnant women belonged to the "poorest" or "poorer" wealth index category and when prenatal care was provided by a midwife in a private facility. CONCLUSION: The prevalence of cesarean sections in Peru during 2021 is 33.75%, warranting evaluation of strategies to regulate their indiscriminate use in each system.

Efecto contráctil del extracto acuoso de Artemisia absinthium (ajenjo) frente a oxitocina en útero aislado de ratas / Contractile effect of aqueous extract of Artemisia absinthium (ajenjo) against oxytocin in isolated uterus of rats

RESUMEN Introducción. El uso de Artemisia absinthium (ajenjo) en el trabajo de parto es ampliamente empleado en países de la región; sin embargo, no hay evidencia científica suficiente de su eficacia y seguridad, lo que representa un alto riesgo maternofetal. Objetivo. El propósito fue evaluar el efecto contractil de la Artemisia absinthium (ajenjo) en comparación a la oxitocina en útero aislado de ratas. Métodos. Se separaron 8 ratas Holtzman en i) Grupo experimental: Artemisia dosis 5, 10, 20, 30, 40 y 50 mg y ii) Grupo control: oxitocina 10-6 M. Se montaron los úteros en un baño de órganos aislados y se registraron contracciones por 5 minutos. Resultados. La frecuencia de contracciones con ajenjo 40 y 50 mg fueron comparables con oxitocina (p>0,05). Asimismo, dosis de 20 y 30 mg de Artemisia provocaron contracciones significativamente más duraderas que la oxitocina. La intensidad resultó ser comparable con oxitocina con dosis de 20, 40 y 50 mg de Artemisia. Conclusión. El extracto acuoso de Artemisia absinthium presentó efecto contráctil similar a la oxitocina y dependiente de la dosis en útero aislado de ratas.

ABSTRACT Introduction. The use of Artemisia absinthium (wormwood) in labour is widely used in countries in the region; however, there is no enough scientific evidence of its efficacy and safety, which represents a high maternalfetal risk. Objective. The purpose was to assess the contractile effect of Artemisia absinthium (wormwood) compared to oxytocin in utero isolated from rats. Methods. Eight Holtzman rats were separated into i) Experimental group: Artemisia dose 5, 10, 20, 30, 40, and 50 mg and ii) Control group: oxytocin 10-6 M. The uteruses were mounted in an isolated organ bath, and contractions were recorded for 5 minutes. Results. The frequency of contractions with wormwood 40 and 50 mg were comparable with oxytocin (p>0.05). Likewise, doses of 20 and 30 mg of Artemisia caused significantly longer-lasting contractions than oxytocin. The intensity was found to be comparable with oxytocin at doses of 20, 40, and 50 mg of Artemisia. Conclusion. The aqueous extract of Artemisia absinthium has a contractile effect similar to oxytocin and is dose dependent in utero isolated from rats.
