Objective: To determine the individual learning curves for cordocentesis in a low-cost simulator for maternal-fetal medicine (MFM) fellows. Methods: This observational, descriptive, educational, and prospective study was performed from July through November 2022. After an introductory course based on a standardized technique for cordocentesis, each second-year MFM fellow who accepted to participate in the study performed this procedure using a low-cost simulation model, and experienced operators supervised the cordocenteses. Learning curves were then created using cumulative sum analysis (CUSUM). Copyright © 1999-2024 John Wiley & Sons.

Importance: Labor epidural placement can cause significant procedural anxiety for patients. Behavioral interventions, such as mindful meditation, can effectively reduce anxiety, including during pregnancy. Objective: This study aimed to assess the impact of a 10-minute mindful meditation session on anxiety and pain during labor epidural placement. Design, Setting, Participants, Intervention, and Outcome Measures: Pregnant women were recruited and randomized into 2 groups: A 10-minute guided mindful meditation, or a neutral content recording, both delivered via headphones before the epidural procedure as a recording. After the procedure, participants reported their levels of anxiety, pain, and satisfaction. Linear regression analyses were used to evaluate the main effects of the intervention on anxiety, pain, and satisfaction. Additionally, an exploratory post hoc moderation analysis assessed the role of baseline pain catastrophizing and its interaction with the intervention. Results: A total of 100 participants were included (50 per group). There were no overall main effect of mindful meditation on primary outcomes of anxiety and pain, or secondary outcome of procedural satisfaction, compared to the neutral content recording (P’s > .05). Exploratory post hoc analysis indicated a moderation of treatment effect, such that participants with higher baseline pain catastrophizing experienced greater benefits from mindful meditation compared to neutral content on anxiety (b = −0.18, P = .01) and pain (b = −0.14, P = .03). Conclusions and Relevance: While no overall group-level effects of mindful meditation were found, exploratory analysis suggested that the intervention may be more beneficial for participants with high baseline pain catastrophizing. Future studies enrolling a larger sample, or enriching for patients with these characteristics are needed to confirm these results. ©The authors ©Oxford University Press.

Introduction: Episiotomy remains a widely performed procedure in many countries, despite international recommendations favoring a restrictive approach. In Mexico, high rates persist in several settings, including public hospitals. Understanding the factors that sustain this practice is key to designing evidence-based respectful birth care strategies. This study aimed to explore healthcare professionals' perspectives on the decision-making process, performance, and perceived consequences of episiotomy, and to engage them in the co-design of behavioral science–informed interventions to promote its restrictive use. Methods: A two-phase qualitative study was conducted in two public hospitals in Mexico, as part of a broader project aimed at promoting the restrictive use of episiotomy. In Phase 1, we conducted 22 semi-structured interviews with maternal health care workers, selected through purposive sampling. Interviews were analyzed inductively using iterative coding and thematic grouping. In Phase 2, group interviews were conducted to discuss findings and collaboratively design interventions for a future pilot quasi-experimental study. Results: Episiotomy decisions are often guided by clinical and preventive considerations. Non-clinical factors, including productivity burdens and training, also contributed to the high rates of episiotomy. Despite the absence of formal institutional monitoring of episiotomy rates, professionals expressed a strong interest in receiving feedback and training. Conclusion: Episiotomy practices in this setting are influenced by clinical, systemic, and educational factors. Addressing potential overuse of episiotomy requires institutional feedback systems, evidence-based training, and strategies to improve dignity in care. Engaging stakeholders through a participatory approach helps ensure that potential interventions are contextually relevant and feasible to implement. ©the authors © Wiley.

Background: Autoimmune liver disease (AILD) recurrence is common after liver transplantation (LT). While several risk factors for recurrence have been identified, their combined predictive value has yet to be thoroughly investigated. Aim: To evaluate the combined predictive value of clinical and laboratory risk factors for AILD recurrence after LT. Methods: This retrospective cohort study included 79 patients with AILD who underwent LT at a single liver transplant center. We compared clinical and laboratory variables between patients with and without recurrent disease and assessed the predictive performance of these factors using four logistic regression models and their corresponding area under the receiver operating characteristic curve (AUC). Results: Recurrent AILD occurred in 26.58% of patients (95%CI: 17-38), the median time to recurrence was 28 months (interquartile range: 16-38). Patients with recurrent AILD had significantly higher pre-transplant Child-Pugh scores [11.61 ± 1.16 vs 10.58 ± 1.96 points; odds ratio (OR) = 1.43, 95%CI: 1.03-2.00; P = 0.032] and model for end-stage liver disease score (MELD) (22.76 ± 5.47 vs 18.81 ± 7.24 points; OR = 1.08, 95%CI: 1.01-1.16; P = 0.032), compared to those without recurrence. Additionally, baseline alanine aminotransferase (ALT) > 2 times the upper limit of normal (ULN) was significantly associated with recurrence (31% vs 57.1%; OR = 2.96, 95%CI: 1.06-8.28; P = 0.038). Our models, incorporating several risk variables, demonstrated moderate predictive ability for AILD recurrence. The AUCs were as follows: (1) Model 1 (AUC = 0.75, 95%CI: 0.58-0.87); (2) Model 2 (AUC = 0.74, 95%CI: 0.59-0.90); (3) Model 3 (AUC = 0.72, 95%CI: 0.58-0.88); and (4) Model 4 (AUC = 0.63, 95%CI: 0.40-0.76), with no statistically significant difference between the models (P = 0.488). Conclusion: Higher pre-transplant Child-Pugh and MELD scores, as well as ALT > 2 ULN, were associated with an increased risk of AILD recurrence. ©The authors ©Baishideng Publishing Group Inc.

The dural puncture epidural (DPE) technique has a faster onset, better sacral spread, and improved bilateral coverage when compared to the conventional epidural (EPL) technique. Whether these qualities translate into a lower bupivacaine dose to provide initial analgesia is unknown. We sought to determine the effective dose of bupivacaine to achieve initial (first 30 minutes) labor analgesia in 90% of patients (ED90) with the DPE and EPL techniques, using a biased-coin, sequential allocation method. A total of 100 women of mixed parity with term, singleton gestation at ≤5 cm dilation with no major comorbidities were randomized to receive a DPE or an EPL technique. An experienced anesthesiologist performed these techniques and administered an allocated dose of plain bupivacaine diluted with isotonic sterile 0.9% saline to a total volume of 20 mL via the EPL catheter. Bupivacaine doses for each subject were determined by the response of the previous subject, using a biased-coin sequential allocation method, with success defined by a numeric rating scale (NRS) < 3 at 30 minutes. Outcome assessments were performed by an investigator blinded to the technique and bupivacaine dose. Sensory and motor blockade and maternal or fetal side effects were recorded every 5 minutes for the first 30 minutes. The ED90 of bupivacaine with each technique was estimated using centered isotonic regression. A total of 95 women were included in the final analysis. The ED90 of bupivacaine was estimated at 29.30 mg (90% confidence interval [CI], 28.55–31.56) with a DPE technique and 45.25 mg (90% CI, 42.80–52.03) with an EPL technique. Using a biased-coin, sequential allocation method, the DPE technique requires less bupivacaine to achieve effective initial analgesia (ED90) when compared to the EPL technique.

Objective: To assess the predictive value of abdominal circumference growth velocity (ACGV) between the second and third trimesters to predict adverse perinatal outcomes in a cohort of small-for-gestational-age fetuses without evidence of placental insufficiency (i.e. fetal growth restriction). Material and methods: This is a single-center retrospective cohort study of all singleton pregnancies with small-for-gestational-age fetuses diagnosed and delivered at a quaternary institution. Crude and adjusted odds ratios (ORs) and corresponding confidence intervals (CIs) were calculated via logistic regression models to assess the potential association between abnormal ACGV (i.e. ≤10th centile) and adverse perinatal outcomes defined as a composite outcome (i.e. umbilical artery pH <7.1, 5-min Apgar score <7, admission to the neonatal intensive care unit, hypoglycemia, intrapartum fetal distress requiring expedited delivery, and perinatal death). Furthermore, the area under the receiver-operating characteristic curve (AUC) of three logistic regression models based on estimated fetal weight and ACGV for predicting the composite outcome is also reported.

While the risk of adverse perinatal outcomes decreases with increasing fetal weight percentile, no percentile completely eliminates that risk. Objective: The aim of this study was to compare perinatal outcomes between fetuses with an EFW between the 10th and 20th percentiles and those with an EFW between the 20th and 90th percentiles (i.e., >20 and <90) at the beginning of the accelerated growth stage (28.0–30.0 weeks’ gestation). Methods: We conducted a retrospective cohort study of singleton pregnancies managed at a quaternary center in Mexico City (2017–2024). Outcomes were compared based on EFW percentiles at 28.0–30.0 weeks. The primary outcome was adverse neonatal outcome (ANeO), defined as the presence of at least one of the following: umbilical artery pH ≤ 7.1, 5 min Apgar ≤ 7, NICU admission, early neonatal hypoglycemia, non-reassuring fetal status, respiratory distress syndrome, intraventricular hemorrhage, hypoxic–ischemic encephalopathy, or perinatal death. Secondary outcomes included progression to fetal growth restriction (FGR) and low birth weight. Modified Poisson regression was used to estimate adjusted risk ratios (aRRs) with 95% confidence intervals (CIs). Results: Among 650 cases, ANeO occurred in 45.8% of fetuses in the 10th–20th percentile group vs. 29.4% in the 20th–90th percentile group (aRR: 1.51, 95% CI: 1.22–1.86; p < 0.001). FGR and low birth weight were also more frequent in the 10th–20th percentile group (21.1% and 27.6% vs. 6.4% and 5.8%, respectively; p < 0.001). Conclusions: Fetuses between the 10th and 20th percentiles at 28–30 weeks have increased risks of neonatal morbidity, FGR, and low birth weight. ©The authors ©Diagnostics © MDPI AG.
