Nomogram for predicting early hypophosphatemia in term infants.

BACKGROUND: Physiological processes rely on phosphate, which is an essential component of adenosine triphosphate (ATP). Hypophosphatasia can affect nearly every organ system in the body. It is crucial to monitor newborns with risk factors for hypophosphatemia and provide them with the proper supplements. We aimed to evaluate the risk factors and develop a nomogram for early hypophosphatemia in term infants. METHODS: We conducted a retrospective study involving 416 term infants measured serum phosphorus within three days of birth. The study included 82 term infants with hypophosphatemia (HP group) and 334 term infants without hypophosphatemia (NHP group). We collected data on the characteristics of mothers, newborn babies, and childbirth. Furthermore, univariate and multivariate logistic regression analyses were performed to identify independent risk factors for hypophosphatemia in term infants, and a nomogram was developed and validated based on the final independent risk factors. RESULTS: According to our analysis, the multivariate logistic regression analysis showed that male, maternal diabetes, cesarean delivery, lower serum magnesium, and lower birth weight were independent risk factors for early hypophosphatemia in term infants. In addition, the C-index of the developed nomogram was 0.732 (95% CI = 0.668-0.796). Moreover, the calibration curve indicated good consistency between the hypophosphatemia diagnosis and the predicted probability, and a decision curve analysis (DCA) confirmed the clinical utility of the nomogram. CONCLUSIONS: The analysis revealed that we successfully developed and validated a nomogram for predicting early hypophosphatemia in term infants.

EUROPEAN ASSOCIATION OF PERINATAL MEDICINE (EAPM) EUROPEAN MIDWIVES ASSOCIATION (EMA) Joint position statement: Caesarean delivery rates at a country level should be in the 15-20 % range.

While cesarean deliveries performed for health indications can save lives, unnecessary cesareans cause unjustifiable health risks for the mother, newborn, and for future pregnancies. Previous recommendations for cesarean delivery rates at a country level in the 10-15% range are currently unrealistic, and the proposed concept that striving to achieve specific rates is not important has resulted in a confusing message reaching healthcare professionals and the public. It is important to have a clear understanding of when cesarean delivery rates are deviating from internationally acceptable ranges, to trigger the implementation of healthcare policies needed to correct this problem. Based on currently existing scientific evidence, we recommend that cesarean delivery rates at a country level should be in the 15-20% range. This advice is based on the demonstration of decreased maternal and neonatal mortalities when national cesarean delivery rates rise to circa 15%, but values exceeding 20% are not associated with further benefits. It is also based on real-world experiences from northern European countries, where cesarean delivery rates in the 15-20% range are associated with some of the best maternal and perinatal quality indicators in the world. With the increase in cesarean delivery rates projected for the coming years, experience in provision of intrapartum care may come under threat in many hospitals, and recovering from this situation is likely to be a major challenge. Professional and scientific societies, together with healthcare authorities and governments need to prioritize actions to reverse the upward trend in cesarean delivery rates observed in many countries, and to strive to achieve values as close as possible to the recommended range.

Third-trimester fetoscopic ablation therapy for types II and III vasa previa.

BACKGROUND: Vasa previa is an obstetrical condition in which fetal vessels located near the cervix traverse the fetal membranes unprotected by underlying placenta. Type I vasa previa arises directly from a velamentous cord root, whereas types II and III arise from an accessory lobe or a distal lobe of the same placenta, respectively. Fetoscopic laser ablation for types II and III vasa previa is a novel therapeutic option with benefits that include surgical resolution of the vasa previa, avoidance of prolonged hospitalization, and opportunity for a term vaginal delivery. The potential risks of fetoscopy can be mitigated by delaying laser surgery until a gestational age of 31 to 33 weeks, immediately before anticipated hospitalized surveillance. OBJECTIVE: This study aimed to assess feasibility and outcomes of types II and III vasa previa patients treated via fetoscopic laser ablation in the third trimester. STUDY DESIGN: This is a retrospective study of singleton pregnancies with types II and III vasa previa treated with fetoscopic laser ablation at a gestational age ≥31 weeks at a single center between 2006 and 2022. Pregnancy and newborn outcomes were assessed. Continuous variables are expressed as mean±standard deviation. RESULTS: Of 84 patients referred for vasa previa, 57 did not undergo laser ablation: 19 either had no or resolved vasa previa, 25 had type I vasa previa (laser-contraindicated), and 13 had type II or III vasa previa but declined laser treatment. Of the remaining 27 patients who underwent laser ablation, 7 were excluded (laser performed at <31 weeks and/or twins), leaving 20 study patients. The mean gestational age at fetoscopic laser ablation was 32.0±0.6 weeks, and total operative time was 62.1±19.6 minutes. There were no perioperative complications. All patients had successful occlusion of the vasa previa vessels (1 required a second procedure). All patients were subsequently managed as outpatients. The mean gestational age at delivery was 37.2±1.8 weeks, the mean birthweight was 2795±465 g, and 70% delivered vaginally. Neonatal intensive care unit admission occurred in 3 cases: 1 for respiratory distress syndrome and 2 for hyperbilirubinemia requiring phototherapy. There were no cases of neonatal transfusion, intraventricular hemorrhage, sepsis, patent ductus arteriosus, or death. CONCLUSION: Laser ablation for types II and III vasa previa at 31 to 33 gestational weeks was technically achievable and resulted in favorable outcomes.

Effects of the aroma of lemone verbena (Aloysia citriodora Paláu) essential oil on anxiety and the hemodynamic profile before cesarean section: A randomized clinical trial.

Background: Aromatherapy is a noninvasive method used for alleviating anxiety. Lemon verbena (Aloysia citriodora Paláu, LV) has been frequently used in traditional medicine as an anxiolytic agent due to its pharmacological ingredients. Objective: This randomized controlled trial aimed to assess the effects of inhaling essential oil of LV on the level of anxiety and subsequent hemodynamic changes before cesarean section. Methods: The recent study was a randomized single-blind trial. Participants (n = 84) were randomly divided into two groups: LV essential oil (group A) and placebo (group B). The intervention group underwent aromatherapy using three drops of LV essential oil at a distance of 10 cm for 30 min. The placebo group received aromatherapy in a similar fashion. The State-Trait Anxiety Inventory of Spielberger questionnaire was administered before and 5 min after aroma inhalation. Vital signs were recorded before and after aromatherapy. Likewise, pain severity was assessed using the Numeric Rating Scale and vital signs were recorded. Data were analyzed using t-test, χ 2, and the Kolmogrov-Smirnov test through SPSS21 software. Results: Anxiety level was significantly attenuated in group A after aromatherapy. Heart rate, respiratory rate, and blood pressure decreased after inhalation; but no significant variation of pain scores was observed after inhalation in both groups. Conclusion: We concluded that LV decreased preoperative anxiety in this recent study, therefore, aromatherapy with LV essential oil as a preemptive adjuvant to relieve anxiety before cesarean section is recommended by us; although more studies are required to endorse the results.

Self-monitoring of blood glucose two-weekly versus weekly in gestational diabetes on nutrition therapy: A randomized trial.

OBJECTIVE: To evaluate 4-point per day self-monitoring of blood glucose (SMBG) every 2 weeks compared with every week. METHODS: A total of 104 patients with lifestyle-controlled gestational diabetes (GDMA1) were randomized to 2-weekly or weekly 4-point per day (fasting on awakening and 2-h post-meals) SMBG. Primary outcome was the change in glycated hemoglobin (HbA1c) level from enrollment to 36 weeks of pregnancy across trial arms. The non-inferiority margin was an HbA1c increase of 0.2%. RESULTS: The mean difference for change in HbA1c from enrollment to 36 weeks was 0.003% (95% confidence interval [CI] -0.098% to +0.093%), within the 0.2% non-inferiority margin. The change in HbA1c level increased significantly within both trial arms-0.275% ± 0.241% (P < 0.001) in 2-weekly arm versus 0.277% ± 0.236% (P < 0.001) in the weekly arm. Participants randomized to 2-weekly SMBG were significantly less likely to receive anti-glycemic treatment-5/52 (9.6%) versus 14/50 (28.0%) (relative risk 0.34, 95% CI 0.13-0.88; P = 0.017). All secondary outcomes-maternal weight gain, preterm delivery, cesarean delivery, birthweight, and neonatal admission-were not significantly different. CONCLUSIONS: In GDMA1, 2-weekly is non-inferior to weekly SMBG on the change in HbA1c level. Two-weekly SMBG appeared to be adequate for monitoring women with GDMA1. CLINICAL TRIAL REGISTRATION: This study was registered in ISRCTN registry on March 25, 2022 with trial identification number: ISRCTN13404790 (https://doi.org/10.1186/ISRCTN13404790). The first participant was recruited on April 12, 2022.

Live birth prevalence of hemolytic disease of the fetus and newborn in the United States from 1996 to 2010.

BACKGROUND: Hemolytic disease of the fetus and newborn (HDFN) is mediated by maternal alloantibodies, a consequence of immune sensitization during pregnancy with maternal-fetal incompatibility with ABO, Rhesus factor (Rh), and/or other red blood cell antigens. RhD, Kell, and other non-ABO alloantibodies are the primary cause of moderate to severe HDFN, whereas ABO HDFN is typically mild. HDFN live birth prevalence owing to Rh alloimmunization among newborns in the United States was last estimated to be 106 per 100,000 births in 1986. HDFN live birth prevalence owing to all alloantibodies was estimated to be 817 to 840 per 100,000 in Europe. There is a need for updated prevalence estimates in the United States and a better understanding of disease demographics, severity, and treatments. OBJECTIVE: This study aimed to estimate the live birth prevalence of HDFN and the proportion of severe cases of HDFN in the United States, to describe the associated risk factors, and to compare the clinical outcomes and treatments among healthy newborns, newborns with HDFN, and newborns who are sick without HDFN using a nationally representative hospital discharge database. STUDY DESIGN: In this retrospective, observational cohort study, we used data from the 1996 to 2010 National Hospital Discharge Survey to identify live births, defined by inpatient visits with the newborn flag, with and without a diagnosis of HDFN across 200 to 500 sampled hospitals (≥6 beds) per year. Patient and hospital characteristics, alloimmunization status, disease severity, treatment, and clinical outcomes were evaluated. Frequencies and weighted percentages were calculated for all variables. Logistic regression was used to compare the characteristics between newborns with HDFN and other newborns using odds ratios. RESULTS: Of 480,245 live births identified, 9810 HDFN cases were recorded. When weighted to the United States population, this corresponded to a live birth prevalence of 1695 per 100,000 live births. Compared with other newborns, newborns with HDFN were more likely to be female, Black, living in the South (vs the Midwest or West), and treated at larger (>100 beds) and government-owned hospitals. ABO and Rh alloimmunization accounted for 78.1% and 4.3% of newborns with HDFN, respectively, whereas HDFN caused by other antigens, such as Kell and Duffy, accounted for 17.6% of the cases. Among newborns with HDFN, 22% received phototherapy, 1% received simple transfusions, and 0.5% received exchange transfusions or intravenous immunoglobulin. Newborns affected by HDFN caused by Rh alloimmunization were more likely to require medical interventions, including simple or exchange transfusions, and more likely to be delivered by cesarean delivery. Overall, HDFN was associated with a longer hospital length of stay in the neonatal intensive care unit when compared with healthy and other sick newborns, a higher rate of cesarean delivery, and a higher rate of nonroutine discharge than healthy newborns. CONCLUSION: Overall, the live birth prevalence of HDFN was higher than those previously reported, whereas Rh-induced HDFN live birth prevalence was similar to those previously reported. HDFN live birth prevalence owing to Rh alloimmunization decreased over time, likely because of continued Rh immune globulin prophylaxis. Treatment patterns for newborns with HDFN and the comparative clinical outcomes when compared with healthy newborns confirm the continued clinical needs of this population.

Midwifery care during labor and birth in the United States.

The intrapartum period is a crucial time in the continuum of pregnancy and parenting. Events during this time are shaped by individuals' unique sociocultural and health characteristics and by their healthcare providers, practice protocols, and the physical environment in which care is delivered. Childbearing people in the United States have less opportunity for midwifery care than in other high-income countries. In the United States, there are 4 midwives for every 1000 live births, whereas, in most other high-income countries, there are between 30 and 70 midwives. Furthermore, these countries have lower maternal and neonatal mortality rates and have consistently lower costs of care. National and international evidences consistently report that births attended by midwives have fewer interventions, cesarean deliveries, preterm births, inductions of labor, and more vaginal births after cesarean delivery. In addition, midwifery care is consistently associated with respectful care and high patient satisfaction. Midwife-physician collaboration exists along a continuum, including births attended independently by midwives, births managed in consultation with a physician, and births attended primarily by a physician with a midwife acting as consultant on the normal aspects of care. This expert review defined midwifery care and provided an overview of midwifery in the United States with an emphasis on the intrapartum setting. Health outcomes associated with midwifery care, specific models of intrapartum care, and workforce issues have been presented within national and international contexts. Recommendations that align with the integration of midwifery have been suggested to improve national outcomes and reduce pregnancy-related disparities.

Chinese Medicine Plaster as A New Treatment for Surgical Site Infection in Patients with Cesarean Delivery: A Randomized, Double-Blind, Controlled Trial.

OBJECTIVE: To evaluate the efficacy of Chinese plaster containing rhubarb and mirabilite on surgical site infection (SSI) in patients with cesarean delivery (CD) by performing a randomized controlled trial. METHODS: This randomized controlled trial included 560 patients with CD due to fetal head descent enrolled at a tertiary teaching center between December 31, 2018 and October 31, 2021. Eligible patients were randomly assigned to a Chinese medicine (CM) group (280 cases) or a placebo group (280 cases) by a random number table, and were treated with CM plaster (made by rhubarb and mirabilite) or a placebo plaster, respectively. Both courses of treatment lasted from the day 1 of CD, followed day 2 until discharge. The primary outcome was the total number of patients with superficial, deep and organ/space SSI. The secondary outcome was duration of postoperative hospital stay, antibiotic intake, and unplanned readmission or reoperation due to SSI. All reported efficacy and safety outcomes were confirmed by a central adjudication committee that was unaware of the study-group assignments. RESULTS: During the recovery process after CD, the rates of localized swelling, redness and heat were significantly lower in the CM group than in the placebo group [7.55% (20/265) vs. 17.21% (47/274), P<0.01]. The durution of postoperative antibiotic intake was shorter in the CM group than in the placebo group (P<0.01). The duration of postoperative hospital stay was significantly shorter in the CM group than in the placebo group (5.49 ± 2.68 days vs. 8.96 ± 2.35 days, P<0.01). The rate of postoperative C-reactive protein elevation (≽100 mg/L) was lower in the CM group than in the placebo group [27.6% (73/265) vs. 43.8% (120/274), P<0.01]. However, there was no difference in purulent drainage rate from incision and superficial opening of incision between the two groups. No intestinal reactions and skin allergies were found in the CM group. CONCLUSIONS: CM plaster containing rhubarb and mirabilite had an effect on SSI. It is safe for mothers and imposes lower economic and mental burdens on patients undergoing CD. (Registration No. ChiCTR2100054626).

How does the ERAS protocol work in patients who underwent cesarean section? (HERMES study).

OBJECTIVE: To assess the effect of the enhanced recovery after surgery (ERAS) protocol for cesarean deliveries (CD) on postoperative outcomes. METHODS: This multicenter prospective cohort study was conducted in six different centers between September 2020 and March 2021 and involved women who underwent either planned or unplanned CD. The primary outcome was time to the first passage of flatus following CD. Secondary outcomes included postoperative pain score, postoperative complications, and patient satisfaction. The protocol included early postoperative oral intake of ice cream and coffee, multimodal analgesia, antiemetic medications, and early ambulation. RESULTS: A total of 448 patients were included. The median time to the first passage of flatus was 10 h in the Hermes group and 18 hours in the control group (P < 0.001). Postoperative visual analog scale scores were significantly higher in the control group. Patient satisfaction scores and the frequency of postoperative complications did not differ between the groups (P = 0.08, P = 0.604, respectively). CONCLUSIONS: The ERAS protocol, including early serving of ice cream and coffee in the early postoperative period, enabled early discharge and a faster return of bowel function. Implementation of the ERAS protocol for patients who underwent planned and unplanned CD appeared to be safe and effective.

Efficacy of electroacupuncture combined with intravenous patient-controlled analgesia after cesarean delivery: a randomized clinical trial.

BACKGROUND: Electroacupuncture is a nonpharmacologic intervention for analgesia that is widely recognized as therapy for pain. However, the clinical efficacy of electroacupuncture combined with patient-controlled intravenous analgesia for postoperative analgesia after cesarean delivery remains unclear. OBJECTIVE: This study aimed to assess the efficacy of electroacupuncture + patient-controlled intravenous analgesia for postoperative analgesia after cesarean delivery, determine the optimal frequency for the best analgesic effect, and explore the underlying mechanism of action. STUDY DESIGN: This single-center, randomized, single-blinded, sham acupuncture controlled clinical trial was conducted at a tertiary university hospital in China. Female patients who underwent cesarean delivery and received fentanyl as patient-controlled intravenous analgesia for postoperative analgesia were enrolled. Patients were after surgery randomized to receive 2 Hz electroacupuncture treatment (n=53), 20/100 Hz electroacupuncture treatment (n=53), or sham electroacupuncture treatment (n=52) (controls). The 2 electroacupuncture groups received electroacupuncture treatment at 2 or 20/100 Hz at the ST36 and SP6 points, whereas, in the sham electroacupuncture group, sham electroacupuncture was performed at nonmeridian points with nonenergized electroacupuncture instruments. Of note, 4 electroacupuncture treatments were performed in all groups at 6, 12, 24, and 48 hours after surgery. The primary outcome was the number of analgesic pump compressions at 48 hours after surgery. The secondary outcomes included number of analgesic pump compressions at 6, 12, and 24 hours after surgery; pain scores at 6, 12, 24, and 48 hours after surgery; fentanyl consumption at 48 hours after surgery; interleukin 6 and procalcitonin levels at 12 and 48 hours after surgery; and time to first exhaust. RESULTS: Overall, 174 primigravida women were included in the intention-to-treat analysis. The number of analgesic pump compressions and pain scores at all 4 time points and fentanyl consumption at 48 hours after surgery were significantly lower in the electroacupuncture treatment groups than in the sham electroacupuncture group (P<.001). CONCLUSION: Electroacupuncture + patient-controlled intravenous analgesia had a significantly better analgesic effect than sham electroacupuncture + patient-controlled intravenous analgesia within 48 hours after surgery. Thus, electroacupuncture can be considered safe and effective and may improve the efficacy of patient-controlled intravenous analgesia for pain management after cesarean delivery. Electroacupuncture can be recommended as a routine complementary therapy for pain control after cesarean delivery.

Peripartum outcomes after combined myo-inositol, probiotics, and micronutrient supplementation from preconception: the NiPPeR randomized controlled trial.

BACKGROUND: Evidence that nutritional supplementation before and during pregnancy improves peripartum outcomes is sparse. In the Nutritional Intervention Preconception and During Pregnancy to Maintain Healthy Glucose Metabolism and Offspring Health (NiPPeR) trial, we previously reported that a combined myo-inositol, probiotics, and micronutrient supplement started at preconception showed no difference in the primary outcome of gestational glycemia, but did reduce the risk of preterm delivery, preterm prelabor rupture of membranes, and major postpartum hemorrhage. OBJECTIVE: This study aimed to examine the hypothesis that a reduction in major postpartum hemorrhage following a combined nutritional (myo-inositol, probiotics, and micronutrients) intervention is linked with promotion of labor progress and reduced operative delivery. STUDY DESIGN: This double-blind randomized controlled trial recruited 1729 women from the United Kingdom, Singapore, and New Zealand, aged 18 to 38 years, and planning conception between 2015 and 2017. The effects of the nutritional intervention compared with those of a standard micronutrient supplement (control), taken at preconception and throughout pregnancy, were examined for the secondary outcomes of peripartum events using multinomial, Poisson, and linear regression adjusting for site, ethnicity, and important covariates. RESULTS: Of the women who conceived and progressed beyond 24 weeks' gestation with a singleton pregnancy (n=589), 583 (99%) provided peripartum data. Between women in the intervention (n=293) and control (n=290) groups, there were no differences in rates of labor induction, oxytocin augmentation during labor, instrumental delivery, perineal trauma, and intrapartum cesarean delivery. Although duration of the first stage of labor was similar, the second-stage duration was 20% shorter in the intervention than in the control group (adjusted mean difference, -12.0 [95% confidence interval, -22.2 to -1.2] minutes; P=.029), accompanied by a reduction in operative delivery for delayed second-stage progress (adjusted risk ratio, 0.61 [0.48-0.95]; P=.022). Estimated blood loss was 10% lower in the intervention than in the control group (adjusted mean difference, -35.0 [-70.0 to -3.5] mL; P=.047), consistent with previous findings of reduced postpartum hemorrhage. CONCLUSION: Supplementation with a specific combination of myo-inositol, probiotics, and micronutrients started at preconception and continued in pregnancy reduced the duration of the second stage of labor, the risk of operative delivery for delay in the second stage, and blood loss at delivery.

Use of calendula ointment after episiotomy: a randomized clinical trial.

OBJECTIVE: Episiotomy is associated with an increased risk of postpartum pain, bleeding, and dyspareunia. The hypothesis of this trial was that in women with singleton pregnancy, and spontaneous labor at term, use of calendula ointment would reduce pain after episiotomy. METHODS: This was a single-center parallel group randomized trial of women with singleton pregnancies and spontaneous labor at term who were randomized to either use of calendula ointment (i.e. intervention group) or standard care (i.e. control group) after episiotomy. Eligible women were those with singleton gestations in spontaneous labor and vertex presentation at term. Women with premature rupture of membranes were excluded from the study. Women in the intervention group were recommended use of calendula ointment 4 h after the episiotomy and then every 8 h for 10 days. The primary outcome was the pain level. Pain level was self-reported and recorded using the verbal rating scale (VRS). The effect of the calendula ointment was quantified as mean difference (MD) with 95% confidence interval (CI). RESULTS: During the study, 100 women agreed to take part in the study, underwent randomization, and were enrolled in this trial. Of the 100 randomized women, 50 were randomized to the calendula ointment group, and 50 to the control group. No women were excluded after randomization or lost to follow up.Women who received calendula ointment after episiotomy compared to standard care had a significantly lower pain level starting from day two and during all the follow-up. Calendula ointment also improve wound healing in terms of redness and edema. CONCLUSIONS: Use of calendula ointment significantly reduce pain after episiotomy.

Neonatal outcome of second-stage cesarean delivery versus vacuum extraction among neonates <34 weeks.

OBJECTIVE: Among deliveries <34 weeks, there is inconclusive evidence regarding the preferred route of delivery when there is a need to expedite delivery during the second stage of labor. As it is unreasonable that future randomized controlled trials will be conducted to settle this query, every clinical data concerning this topic, may be helpful. We aim to compare neonatal outcomes among women undergoing emergent cesarean delivery (ECD) versus vacuum-assisted delivery (VAD) during the second stage of labor among singleton gestations <34 weeks. METHODS: A retrospective cohort study including all women who underwent either ECD or VAD at the second stage of labor between 30°/7 and 336/7 weeks, during 2011-2019. The primary outcome was the rate of adverse neonatal outcomes, defined as intrapartum death, mechanical ventilation, asphyxia, respiratory distress syndrome, subgaleal hemorrhage, intraventricular hemorrhage, necrotizing enterocolitis, and phototherapy. RESULTS: Of the 153,672 live singleton deliveries during the study period, 2871 (1.9%) delivered before 34°/7. Of those 1674 (58.3%) delivered vaginally unassisted and 1137 (39.6%) delivered by a CD during the first stage of labor. A total of 60 deliveries were analyzed, with a median gestational age of 32 weeks, interquartile range (IQR) 31-33. Median birth weight at delivery was 1845 g, IQR 1574-2095. Overall 25 (42%) of women were delivered by VAD and 35 by CD (58%). Indications for expeditious delivery did not differ between the study groups. Neonates delivered by VAD had a higher median birth weight (1940 vs. 1620 g, p = .02). Second stage of labor was longer in the ECD group as compared to the VAD group (median 200 vs. 52 min, p = .01). The rate of Apgar score at 1 min <7 was higher among the CD group (10 (40%) vs. 5 (14%), OR [95% CI]: 4.0 (1.1-13.8), p = .03). Longer length of stay was evident in the CD group as compared to the VAD group (median 30 vs. 21 days, p = .001). The rate of composite neonatal adverse outcome was comparable between the study groups. Adverse outcomes were associated with lower body mass index (median 27.7 vs. 34.9, p = .04), higher rate of premature preterm rupture of membranes (40 (91%) vs. 5 (31%), OR [95% CI]: 22.0 (5.0-91.1), p < .001) and labor dystocia as the indication for expedited delivery (38 (86%) vs. 7 (44%), OR [95% CI]: 8.1 (2.1-30.1), p = .001). CONCLUSIONS: Cesarean delivery during the second stage of labor of gestations <34 weeks was associated with a higher rate of lower Apgar scores and longer length of stay. SYNOPSIS: Delivery by second stage CD of premature neonates <34 weeks is associated with a higher rate of lower Apgar score.

Manual rotation of occiput posterior or transverse positions: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: The primary objective of this systematic review was to assess the association between spontaneous vaginal delivery and manual rotation during labor for occiput posterior or transverse positions. Our secondary objective was to assess maternal and neonatal outcomes. DATA SOURCES: An electronic search of PubMed, EMBASE, ClinicalTrials.gov, and the Cochrane Register of Controlled Trials covered the period from January 2000 to September 2021, without language restrictions. STUDY ELIGIBILITY CRITERIA: The eligibility criteria included all randomized trials with singleton pregnancies at ≥37 weeks of gestation comparing the manual rotation groups with the control groups. The primary outcome was the rate of spontaneous vaginal delivery. Additional secondary outcomes were rate of occiput posterior position at delivery, operative vaginal delivery, cesarean delivery, postpartum hemorrhage, obstetrical anal sphincter injury, prolonged second stage of labor, shoulder dystocia, neonatal acidosis, and phototherapy. Subgroup analyses were performed according to types of position (occiput posterior or occiput transverse), techniques used (whole-hand or digital rotation), and parity (nulliparous or parous). METHODS: The quality of each study was evaluated with the revised Cochrane risk-of-bias tool for randomized trials, known as RoB 2. The meta-analysis used random-effects models depending on their heterogeneity, and risks ratios were calculated for dichotomous outcomes. RESULTS: Here, 7 of 384 studies met the inclusion criteria and were selected. They included 1402 women: 704 in the manual rotation groups and 698 in the control groups. Manual rotation was associated with a higher rate of spontaneous vaginal delivery: 64.9% vs 59.5% (risk ratio, 1.09; 95% confidence interval, 1.03-1.16; P=.005; 95% prediction interval, 0.90-1.32). This association was no longer significant after stratification by parity or technique used. Manual rotation was associated with spontaneous vaginal delivery only for the occiput posterior position (risk ratio, 1.08; 95% confidence interval, 1.01-1.15). Furthermore, it was associated with a reduction in occiput posterior or transverse positions at delivery (risk ratio, 0.64; 95% confidence interval, 0.48-0.87) and episiotomies (risk ratio, 0.84; 95% confidence interval, 0.71-0.98). The groups did not differ significantly for cesarean deliveries, operative vaginal deliveries, or neonatal outcomes. CONCLUSION: Manual rotation increased the rate of spontaneous vaginal delivery.

Colostrum IgA1 antibodies recognize antigens from Helicobacter pylori and prevent cytoskeletal changesin human epithelial cells.

Helicobacter pylori is a Gram-negative bacterium found on the luminal surface of the gastric mucosa in at least 50% of the world's human population. The protective effect of breastfeeding against H. pylori infection has been extensively reported; however, the mechanisms behind this protection remain poorly understood. Human IgA from colostrum has reactivity against H. pylori antigens. Despite that IgA1 and IgA2 display structural and functional differences, their reactivity against H. pylori had not been previously determined. We attested titers and reactivity of human colostrum-IgA subclasses by ELISA, immunoblot, and flow cytometry. Colostrum samples from healthy mothers had higher titers of IgA; and IgA1 mostly recognized H. pylori antigens. Moreover, we found a correlation between IgA1 reactivity and their neutralizing effect determined by inhibition of cytoskeletal changes in AGS cells infected with H. pylori. In conclusion, colostrum-IgA reduces H. pylori infection of epithelial gastric cells, suggesting an important role in preventing the bacteria establishment during the first months of life. As a whole, these results suggest that IgA1 from human colostrum provides protection that may help in the development of the mucosal immune system of newborn children.

The effect of music on anxiety in women undergoing cesarean delivery: a systematic review and meta-analysis.

OBJECTIVE: This study aimed to evaluate the effect of music on anxiety in patients undergoing cesarean delivery. DATA SOURCES: An electronic search of PubMed, CINAHL, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials was performed from inception to November 2020. STUDY ELIGIBILITY CRITERIA: Eligibility criteria included all randomized controlled trials of pregnant women undergoing cesarean delivery who were randomized to either the music intervention or control. Studies needed to measure preoperative, intraoperative, or postoperative anxiety via a visual analog scale, State-Trait Anxiety Inventory, or Zung Self-Rating Anxiety Scale, for inclusion. The primary outcome was intraoperative anxiety during cesarean delivery. Secondary outcomes included preoperative and postoperative anxiety, postoperative pain, postoperative opioid requirements, blood pressure, and heart rate. STUDY APPRAISAL AND SYNTHESIS METHODS: The methodologic quality of the included studies was evaluated using the Cochrane Handbook for Systematic Reviews of Interventions. A meta-analysis was performed using the random-effects model of DerSimonian and Laird to produce a summary of treatment effects in terms of mean difference with 95% confidence intervals. A prespecified subgroup analysis of patients undergoing a scheduled or an unscheduled cesarean delivery was carried out for the main outcomes. RESULTS: Of the 1296 studies screened, 15 met the inclusion criteria (n=613 music group vs n=748 controls). Three trials (n=217 music group vs n=215 controls) reported on intraoperative anxiety specifically. Among studies using a visual analog scale for anxiety assessment, women in the intervention group had lower intraoperative anxiety levels than the controls (mean difference, -0.54; 95% confidence interval, -0.87 to -0.20; I2=0%; n=2 studies). One trial used the State-Trait Anxiety Inventory and 1 trial used the Zung Self-Rating Anxiety Scale for intraoperative anxiety assessment. In both of these studies, music exposure was associated with lower anxiety levels when compared with the controls (State-Trait Anxiety Inventory: mean difference, -2.80; 95% confidence interval, -4.57 to -1.03; Zung Self-Rating Anxiety Scale: mean difference, -4.80; 95% confidence interval, -7.08 to -2.52). In the subgroup analyses, the same relationship persisted when the cesarean delivery was unscheduled and when the music was selected by the patient or by the study team. The effect of music on preoperative and postoperative anxiety varied depending on which anxiety assessment tool was used. Music was also associated with decreased opioid use (mean difference, -0.87; 95% confidence interval, -1.55 to -0.19; I2=0%). CONCLUSION: In patients undergoing a cesarean delivery, music is associated with decreased intraoperative anxiety.

Enhanced Recovery After Cesarean: Current and Emerging Trends.

PURPOSE OF REVIEW: What are the latest enhanced recovery elements for cesarean delivery? RECENT FINDINGS: Enhanced recovery after cesarean delivery (ERAC) provides an evidenced-based system to improve maternal outcomes, functional recovery, maternal-infant bonding, and patient experience. Postsurgical recovery has evolved from a one-dimensional pain score to a holistic multidimensional approach emphasizing faster functional recovery. ERAC involves multidisciplinary efforts of the anesthesiologist, obstetrician, nursing, hospital, and patient. Components of ERAC include preoperative patient education, limited fasting, carbohydrate load, limiting opioids intra- and postoperatively, using scheduled non-opioid analgesics and supplementing with advanced therapies for women at higher risk for pain. ERAC protocols reduce opioid consumption, reduce length of stay, and improve maternal and neonatal outcomes. SUMMARY: Implementing ERAC standardized care will likely be the most important change you can make in your practice to improve outcomes, improve quality care, help address racial disparities, and minimize opioid exposure and potential for addiction.

Cost of Illness in Young Children: A Prospective Birth Cohort Study.

Childhood illness is extremely common and imposes a considerable economic burden on society. We aimed to quantify the overall economic burden of childhood illness in the first three years of life and the impact of environmental risk factors. The study is based on the prospective, clinical mother-child cohort Copenhagen Prospective Studies on Asthma in Childhood (COPSAC2010) of 700 children with embedded randomized trials of fish-oil and vitamin D supplementations during pregnancy. First, descriptive analyses were performed on the total costs of illness, defined as both the direct costs (hospitalizations, outpatient visits, visit to the practitioner) and the indirect costs (lost earnings) collected from the Danish National Health Registries. Thereafter, linear regression analyses on log-transformed costs were used to investigate environmental determinants of the costs of illness. The median standardized total cost of illness at age 0-3 years among the 559 children eligible for analyses was EUR 14,061 (IQR 9751-19,662). The exposures associated with reduced costs were fish-oil supplementation during pregnancy (adjusted geometric mean ratio (GMR) 0.89 (0.80; 0.98), p = 0.02), gestational age in weeks (aGMR = 0.93 (0.91; 0.96), p < 0.0001), and birth weight per 100 g (aGMR 0.98 (0.97; 0.99), p = 0.0003), while cesarean delivery was associated with higher costs (aGMR = 1.30 (1.15; 1.47), p < 0.0001). In conclusion, common childhood illnesses are associated with significant health-related costs, which can potentially be reduced by targeting perinatal risk factors, including maternal diet during pregnancy, cesarean delivery, preterm birth and low birth weight.

Association of Maternal Hyperuricemia with Post-Spinal Hypotension in Pre-Eclamptic Parturients Undergoing Emergency Cesarean Delivery: a Prospective Observational Study.

Pre-eclampsia is commonly associated with higher serum uric acid levels, which is known to increase vascular tone. A previous retrospective study established a positive correlation between raised serum uric acid levels and reduced incidence of post-spinal hypotension. However, until date, this correlation has not been prospectively evaluated in exclusively pre-eclamptic women. Pre-eclamptic parturients undergoing emergency cesarean delivery under subarachnoid block were included. Sample for measuring serum uric acid level was obtained prior to shifting patients for cesarean delivery. Following spinal anesthesia, we recorded episodes of hypotension (fall of mean arterial pressure more than 20% from baseline values), use of vasopressors, and intraoperative blood loss. Our primary objective was to study the association between maternal hyperuricemia and incidence of post-spinal hypotension. Our secondary objectives included amount of vasopressors administered to maintain targeted mean arterial pressure before delivery of the baby, intraoperative blood loss, and immediate neonatal outcome. A total of 95% parturients had hyperuricemia, with mean serum uric acid level being 6.94 ± 0.9 mg/dl. Incidence of post-spinal hypotension was significantly lower in women who had hyperuricemia as compared with those with normal serum uric acid levels (21% vs 75%; p = 0.015). Mean serum uric acid levels were significantly high (p = 0.001) in patients not requiring any vasopressors (7.2 ± 1.2 mg/dl) than in those requiring moderate (5.70 ± 0.79 mg/dl) to high dose (5.75 ± 0.77 mg/dl) of vasopressors. There is a high incidence of hyperuricemia in pre-eclamptic parturients. In these patients, elevated serum uric acid levels is associated with lower incidence of post-spinal hypotension and reduced need of vasopressors to maintain maternal blood pressure within a normal range.
