Vaginal Birth after Cesarean after Zavanelli Maneuver: A Woman’s Right to Choose

引用

Open Journal of Obstetrics and Gynecology 2024年第7期14卷 1091-1095页

作者： Nicole Jenkins Gregory Vurture jonathan d. Baum department of Obstetrics and Gynecology Jersey Shore University Medical Center Neptune NJ USA

Introduction: Vaginal birth after cesarean (VBAC) plays an essential role in lowering cesarean rates. despite endorsement, trial of labor after cesarean (TOLAC) attempt rates remain low, in part due to fear of lawsuits. Zavanelli maneuver is a last resort procedure in the management of shoulder dystocia. We discuss a case of a woman determined to have a vaginal birth after her prior birth was complicated by shoulder dystocia requiring a Zavanelli maneuver. Her physicians were reluctant to allow her a TOLAC given her prior obstetric history. Case: A 34-year-old para 1 with prior cesarean delivery due to shoulder dystocia that required Zavanelli maneuver presents determined to pursue VBAC in her current pregnancy. She considered her delivery route options and addressed her modifiable risk factors. She consulted with multiple perinatologists who agreed that a TOLAC was reasonable, however she had to travel more than 70 miles (from Pennsylvania to New Jersey) to find an obstetrical practice and hospital willing to consider VBAC. She transferred care and the remainder of her prenatal course was uncomplicated. She went into labor at 41 weeks and had a successful VBAC without complication. In a thank you letter to her obstetrician, she described her birth experience as euphoric. Conclusion: This case illustrates how a woman’s choice of delivery route may be impacted by fear of litigation. Local providers focused on her prior delivery instead of her overall improved risk profile. delivery route decisions should be based on a thorough evaluation of all risk factors and individualized to meet the reproductive goals of each woman. .

CAOSA-extracted lignin improves enzymatic hydrolysis of cellulose

Green Energy & Environment 2024年第7期9卷 1101-1111页

The conversion of biomass into sugar platform compounds is very important for the biorefinery industry. Pretreatment is essential to the biomass of the sugar platform, however, the lignin obtained by pretreatment, as a key part of lignocellulose, generally has a passive effect on the enzymatic hydrolysis of cellulose into sugars. In this study, p-TsOH(p-toluenesulfonic acid), dES(deep eutectic solvent) and CAOSA(cooking with active oxygen and solid alkali) pretreatment ways were used to fraction lignin from bamboo biomass. After CAOSA treatment, the hydrolysis efficiency of the pulp was 95.57%. Moreover, the effect of different treatment methods on lignin properties was studied and the promotion effect of lignin was investigated by adding it to the cellulose enzymatic hydrolysis system. In this work, the results showed that CAOSA-extracted lignin with lower ?(1.31–1.25) had a better adsorption effect on the enzyme protein. p-TsOH-extracted lignin with a larger S/G ratio enhanced the inhibition of enzymatic hydrolysis. In addition, the presence of-COOHs in lignin could reduce its inhibitory effect on cellulose saccharification.
