Birthing ball for reducing labor pain: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: Multiple factors are thought to affect a woman's sensation of pain during the process of labor. Birthing balls are round exercise balls upon which a woman sits during labor and performs different movements such as rocking back and forth and pelvic rotation. Midwives and nurses have been using birthing balls (also known as Swiss balls) to increase maternal comfort, widen the pelvic outlet, and facilitate progression of labor for women laboring without an epidural. Therefore, the aim of this systematic review and meta-analysis of randomized controlled trials is to assess whether the use of the birthing ball in labor decreases maternal pain during labor. DATA SOURCES: Research was conducted using PubMed, Scopus, ClinicalTrial.gov, OVID and Cochrane Library as electronic databases. Randomized controlled trials were identified using the following search strategy: "birthing ball" OR "birth ball" OR "swiss ball" OR "exercise ball" AND labor from the inception of each database to June 2019. No restrictions for language or geographic location were applied. STUDY ELIGIBILITY CRITERIA: Selection criteria included randomized trials of pregnant women with a singleton, cephalic fetus who were randomized to either birthing ball or control group (i.e. no birthing ball) for use in labor. STUDY APPRAISAL AND SYNTHESIS METHODS: Seven trials with 533 pregnant women were included. 287 (53.8%) were randomized to the intervention group (birthing ball) and 246 (46.2%) were randomized to the control group (no birthing ball). All analyses were done using an intention-to-treat approach, evaluating women according to the treatment group to which they were randomly allocated in the original trials. The primary outcome was labor pain in the first stage of labor. The summary measures were reported as summary relative risk (RR) or as summary mean difference (MD) with 95% of confidence interval (CI) using the random-effects model of DerSimonian and Laird. RESULTS: Labor pain significantly decreased by 1.70 points in the birthing ball group compared to the control group (MD -1.70 points; 95% CI -2.20 to -1.20). Use of the birthing ball versus no birthing ball did not result in a significant difference in incidence of spontaneous vaginal delivery, operative vaginal delivery, cesarean delivery, or perineal lacerations. CONCLUSION: The birthing ball is an effective method of pain reduction during labor for women laboring without an epidural.

Obstetric A&E unit admission and hospitalization for obstetrical management during COVID-19 pandemic in a third-level hospital of southern Italy.

BACKGROUND: The COronaVIrus Disease 2019 (COVID-19) has spread in Italy since February 2020, inducing the government to call for lockdown of any activity, apart primary needs, during the months March-May 2020. During the lockdown, a reduction of admissions and hospitalizations for ischemic diseases was noticed. Purpose of this study was to observe if there has been the same reduction trend in Accident & Emergency (A&E) unit admissions also for obstetric-gynecological conditions. METHODS: Medical records and electronic clinical databases were searched for all patients who were admitted to the obstetric A&E department or hospitalized at the Gynecology and Obstetrics Unit of University hospital of Naples Federico II, during the quarter March-May in the years 2019 and 2020. The mean ± standard deviation (SD) of monthly admission to the obstetric A&E department and hospitalization of the year 2020 was compared with that of the year 2019, using the unpaired T test with α error set to 0.05 and 95% confidence intervals (95% CI). RESULTS: Admissions were 1483 in the year 2020 and 1786 in 2019. Of total, 1225 (37.5%) women were hospitalized: 583 in the year 2020, 642 in 2019. Mean ± SD of patients monthly admitted to our obstetric A&E department was 494 ± 33.7 in the year 2020, and 595.3 ± 30.9 in 2019, with a mean difference of - 101.3 (95% CI - 103.5 to - 99.1; p < 0.0001). Mean ± SD of patients monthly hospitalized to our department was 194 ± 19.1 in the year 2020, 213.7 ± 4.7 in 2019, with a mean difference of - 19.7 (95% CI - 23.8 to - 15.6; p < 0.0001). CONCLUSION: A significant decrease in the mean of monthly admissions and hospitalizations during the COVID-19 pandemic when compared to the previous year was found also for obstetric-gynecological conditions. Further studies are necessary to assess COVID-19 impact and to take the most appropriate countermeasures.

Uterine carcinosarcoma vs endometrial serous and clear cell carcinoma: A systematic review and meta-analysis of survival.

BACKGROUND: It is unclear whether uterine carcinosarcoma (UCS) is more aggressive than endometrial serous carcinoma (SC) and clear cell carcinoma (CCC). OBJECTIVES: To compare the prognosis of UCS to that of endometrial SC and CCC, through a systematic review and meta-analysis. METHODS: Four electronic databases were searched from January 2000 to October 2020. All studies assessing hazard ratio (HR) for death in UCS vs SC and/or CCC. HRs for death with 95% confidence interval were extracted and pooled by using a random-effect model. A significant P-value <0.05 was adopted. RESULTS: Six studies with 11 029 patients (4995 with UCS, 4634 with SC, 1346 with CCC and 54 with either SC or CCC) were included. UCS showed a significantly worse prognosis than SC/CCC both overall (HR = 1.51; P = 0.008) and at early stage (HR = 1.58; P < 0.001). Similar results were found for UCS vs SC (HR = 1.53; P < 0.001) and UCS vs CCC (HR = 1.60; P < 0.001). CONCLUSIONS: Compared to SC and CCC, UCS has a significantly worse prognosis, with a 1.5-1.6-fold increased risk of death. This might justify a more aggressive treatment for UCS compared to SC and CCC. Further studies are necessary to define the prognostic impact of different molecular subgroups.

Worldwide beliefs among pregnant women on SARS-CoV-2 vaccine: a systematic review.

BACKGROUND: SARS-CoV-2 vaccine has been recommended to pregnant women, but survey studies showed contrasting findings worldwide in relation to the willingness to accept vaccination during pregnancy. OBJECTIVE: To evaluate the evidence from the literature regarding the acceptance rate of the SARS-CoV-2 vaccine in pregnant and breastfeeding women. STUDY DESIGN: We performed a systematic review on the main databases (MEDLINE (PubMed), Scopus, ISI Web of Science) searching for all the peer-reviewed survey studies analyzing the eventual acceptance rate of the SARS-CoV-2 vaccine among pregnant and breastfeeding women. To combine data meta-analyses of proportions and pooled proportions with their 95% confidence intervals (CI) were calculated. RESULTS: 15 studies including 25,839 women were included in the analysis. The proportion of women actually willing to be vaccinated during pregnancy is 49.1% (95% CI, 42.3-56.0), and the proportion of breastfeeding women is 61.6% (95% CI, 50.0-75.0). CONCLUSION: The cumulative SARS-CoV-2 vaccine acceptance rate among pregnant women appears still low. Vaccinal campaign are urgently needed to drive more confidence into the vaccine to help reducing the spread of the infection and the possible consequences during pregnancy.

Being an obstetrics and gynaecology resident during the COVID-19: Impact of the pandemic on the residency training program.

OBJECTIVE: to evaluate the impact of the COVID-19 pandemic on the obstetrics and gynecology residency training program in Italy. STUDY DESIGN: This was a cross-sectional survey study aimed to assess the impact of the COVID-19 pandemic on the obstetrics and gynecology residency training program in Italy. An online survey with 45 questions was sent and completed anonymously by residents after accepting an informed consent. The invitation to the online survey was sent to all the Italian residents in obstetrics and gynecology. Those on maternity leave at the time of the study were excluded. Residents were asked about their routinely activity before the COVID-19 pandemic, and to report the reduction in their clinical practice. They were also asked about psychological impact of COVID-19 on their clinical practice. RESULTS: 933 Italian residents in obstetrics and gynecology, were invited for this survey study. Four-hundred and seventy-six (51 %) completed the survey and were included in the study. Three-hundred and eighty-seven (81.3 %) were female, and 89 (18.7 %) were male. Residents age ranged from 25 to 42. In 71,8 % (342/476) of the cases residents work in a COVID-19 reference Hospitals. One-hundred and eighty-four out of 76 residents (38.6 %) were tested on RT-PCR assay of nasal and pharyngeal swab specimens, and of them 12/184 (6.5 %) were positive to SARS-COV-2. Regarding the use of personal protective equipment (PPE), 267 (56.1 %) reported to receive adequate device, and 379 (79.6 %) felt to be well informed about prevention and management protocols. Three-hundred and thirty-one residents (69.5 %) reported to have managed COVID-19 positive patients. For 54,7 % of respondent residents, training activity in general decreased significantly during the COVID-19 epidemic. A one-third reduction was reported in 31,4 % of the cases, whereas a total suspension of the training in 9,9 % of the cases. In 89,3 % of cases the reduction was caused by the reorganization of work. Anxiety about the professional future was reported in 84 % of the residents, and 59 % of them had the perception that their training was irreversibly compromised. CONCLUSIONS: Among Italian residents in obstetrics and gynecology, COVID-19 pandemic was associated with a significant training impairment.

Fetal Movement Counting and Perinatal Mortality: A Systematic Review and Meta-analysis.

OBJECTIVE: To assess the association of fetal movement counting with perinatal mortality. DATA SOURCES: Electronic databases (ie, MEDLINE, ClinicalTrials.gov, ScienceDirect, the Cochrane Library at the CENTRAL Register of Controlled Trials) were searched from inception until May 2019. Search terms used were: "fetal movement," "fetal movement counting," "fetal kick counting," "stillbirth," "fetal demise," "fetal mortality," and "perinatal death." METHODS OF STUDY SELECTION: We included all randomized controlled trials comparing perinatal mortality in those women randomized to receive instructions for fetal movement counting compared with a control group of women without such instruction. TABULATION, INTEGRATION AND RESULTS: The primary outcome was perinatal mortality. Five of 1,290 identified articles were included, with 468,601 fetuses. Definitions of decreased fetal movement varied. In four of five studies, women in the intervention group were asked to contact their health care providers if they perceived decreased fetal movement; the fifth study did not provide details. Reported reduction in fetal movement usually resulted in electronic fetal monitoring and ultrasound assessment of fetal well-being. There was no difference in the incidence of perinatal outcome between groups. The incidence of perinatal death was 0.54% (1,252/229,943) in the fetal movement counting group and 0.59% (944/159,755) in the control group (relative risk [RR] 0.92, 95% CI 0.85-1.00). There were no statistical differences for other perinatal outcomes as stillbirths, neonatal deaths, birth weight less than 10th percentile, reported decreased fetal movement, 5-minute Apgar score less than 7, neonatal intensive care unit admission or perinatal morbidity. There were weak but significant increases in preterm delivery (7.6% vs 7.1%; RR 1.07, 95% CI 1.05-1.10), induction of labor (36.6% vs 31.6%; RR 1.15, 95% CI 1.09-1.22), and cesarean delivery (28.2% vs 25.3%; RR 1.11, 95% CI 1.10-1.12). CONCLUSION: Instructing pregnant women on fetal movement counting compared with no instruction is not associated with a clear improvement in pregnancy outcomes. There are weak associations with some secondary outcomes such as preterm delivery, induction of labor, and cesarean delivery. SYSTEMATIC REVIEW REGISTRATION: PROSPERO, CRD42019123264.

Early amniotomy after cervical ripening for induction of labor: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE DATA: Timing of artificial rupture of membranes (ie, amniotomy) in induction of labor is controversial, because it has been associated not only with shorter labors, but also with fetal nonreassuring testing, at times necessitating cesarean delivery. The aim of this systematic review and metaanalysis of randomized trials was to evaluate the effectiveness of early amniotomy vs late amniotomy or spontaneous rupture of membranes after cervical ripening. STUDY: The search was conducted with the use of electronic databases from inception of each database through February 2019. Review of articles included the abstracts of all references that were retrieved from the search. STUDY APPRAISAL AND SYNTHESIS METHODS: Selection criteria included randomized clinical trials that compared early amniotomy vs control (ie, late amniotomy or spontaneous rupture of membranes) after cervical ripening with either Foley catheter or prostaglandins at any dose. The primary outcome was the incidence of cesarean delivery. The summary measures were reported as summary relative risk with 95% of confidence interval with the use of the random effects model of DerSimonian and Laird. RESULTS: Four trials that included 1273 women who underwent cervical ripening with either Foley catheter or prostaglandins and then were assigned randomly to either early amniotomy, late amniotomy, or spontaneous rupture of membranes (control subjects) were included in the review. Women who were assigned randomly to early amniotomy had a similar risk of cesarean delivery (31.1% vs 30.9%; relative risk, 1.05; 95% confidence interval, 0.71-1.56) compared with control subjects and had a shorter interval from induction to delivery of approximately 5 hours (mean difference, -4.95 hours; 95% confidence interval, -8.12 to -1.78). Spontaneous vaginal delivery was also reduced in the early amniotomy group, but only 1 of the included trials reported this outcome (67.5% vs 69.1%; relative risk, 0.78; 95% confidence interval, 0.66-0.93). No between-group differences were reported in the other obstetrics or perinatal outcomes. CONCLUSION: After cervical ripening, routine early amniotomy does not increase the risk of cesarean delivery and reduces the interval from induction to delivery.

Sexual Intercourse for Induction of Spontaneous Onset of Labor: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

INTRODUCTION: Sexual intercourse during pregnancy is commonly believed to trigger the onset of contractions and, therefore, labor. However, in low-risk pregnancies, there is neither association with preterm birth, premature rupture of membranes, or low birth weight, nor with spontaneous onset of labor at term. AIM: To evaluate the effectiveness of sexual intercourse for spontaneous onset of labor at term in singleton pregnancies. METHODS: The systematic search was conducted using electronic databases from inception of each database to June 2019. Review of articles also included the abstracts of all references retrieved from the search. Inclusion criteria were randomized controlled trials comparing sexual intercourse in singleton low-risk pregnancies at term with controls (either reduced number of coitus or no coitus) for spontaneous onset of labor. Estimates were pooled using random-effects meta-analysis. MAIN OUTCOME MEASURES: The primary outcome was the incidence of spontaneous onset of labor. The summary measures were reported as summary relative risk with 95% CI using the random-effects model of DerSimonian and Laird. RESULTS: Data extracted from 3 trials, including 1,483 women with singleton pregnancy at term and cephalic presentation, were analyzed. Women who were randomized in the sexual intercourse group had similar incidence of spontaneous onset of labor compared with control subjects (0.82% vs 0.80%; relative risk 1.02, 95% CI 0.98-1.07). CLINICAL IMPLICATION: Sexual intercourse should not be restricted in low-risk term pregnancies. Further studies are needed to properly evaluate the impact of orgasm, penetration, condom use, frequency of intercourse and other factors on induction of labor at term. STRENGTH & LIMITATIONS: Our study has several strengths. The three included trials had low risk of allocation bias; intention-to-treat analysis was used; this is the first meta-analysis on this issue so far. Limitations mainly depend on the design of the included studies. Firstly, compliance to the protocol relied on self-reporting by patients; in addition, not all the features of sexual intercourse could be adequately assessed (orgasm, nipple stimulation, sexual positions, etc.). CONCLUSION: In women with singleton, cephalic, low-risk pregnancies, sexual intercourse at term does not significantly increase the incidence of spontaneous onset of labor.

The Genetics of Non-Syndromic Primary Ovarian Insufficiency: A Systematic Review.

Several causes for primary ovarian insufficiency (POI) have been described, including iatrogenic and environmental factor, viral infections, chronic disease as well as genetic alterations. The aim of this review was to collect all the genetic mutations associated with non-syndromic POI. All studies, including gene screening, genome-wide study and assessing genetic mutations associated with POI, were included and analyzed in this systematic review. Syndromic POI and chromosomal abnormalities were not evaluated. Single gene perturbations, including genes on the X chromosome (such as BMP15, PGRMC1 and FMR1) and genes on autosomal chromosomes (such as GDF9, FIGLA, NOBOX, ESR1, FSHR and NANOS3) have a positive correlation with non-syndromic POI. Future strategies include linkage analysis of families with multiple affected members, array comparative genomic hybridization (CGH) for analysis of copy number variations, next generation sequencing technology and genome-wide data analysis. This review showed variability of the genetic factors associated with POI. These findings may help future genetic screening studies on large cohort of women.

Induction of labor at full-term in pregnant women with uncomplicated singleton pregnancy: A systematic review and meta-analysis of randomized trials.

INTRODUCTION: The lowest incidence of perinatal morbidity and mortality occurs around 39-40 weeks. Therefore, some have advocated induction of uncomplicated singleton gestations once they reach full-term. The aim of the study was to evaluate the risk of cesarean delivery, and any maternal and perinatal effects of a policy of induction of labor in women with full-term uncomplicated singleton gestations. MATERIAL AND METHODS: We performed an electronic search from inception of each database to August 2018. All results were then limited to randomized trial. No restrictions for language or geographic location were applied. Inclusion criteria were randomized clinical trials of asymptomatic women with uncomplicated, singleton gestations at full-term (ie, between 39+0 and 40+6  weeks) who were randomized to either planned induction of labor or control (ie, expectant management). Only trials on asymptomatic singleton gestations without premature rupture of membranes or any other indications for induction evaluating the effectiveness of planned induction of labor in full-term singleton gestations were included. The primary outcome was the incidence of cesarean delivery. RESULTS: Seven randomized clinical trials, including 7598 participants were analyzed. Three studies enrolled only women with favorable cervix, defined as a Bishop score of ≥5 in nulliparous women or ≥4 in multiparous women. One trial included only women aged 35 years or older. Women randomized to the planned induction of labor, received scheduled induction usually at 39+0 to 39+6  weeks of gestation, whereas women in the control group received expectant management usually until 41-42 weeks of gestation, or earlier if medically indicated. Methods of induction usually included cervical ripening, with either misoprostol or Foley catheter, in conjunction with or followed by oxytocin for women with unfavorable cervix, and oxytocin and artificial rupture of membranes for those with favorable cervix. Five trials also used artificial rupture of membranes as a method for induction. Uncomplicated full-term singleton gestations that were randomized to receive induction of labor had similar incidence of cesarean delivery compared with controls (18.6% vs 21.4%; relative risk 0.96, 95% CI 0.78-1.19). Regarding neonatal outcomes, induction of labor at full-term was associated with a significantly lower rate of meconium-stained amniotic fluid (4.0% vs 13.5%; relative risk 0.32, 95% CI 0.18-0.57), and lower mean birthweight (mean difference -98.96 g, 95% CI -126.29 to -71.63) compared with the control group. There were no between-group differences in other adverse neonatal outcomes. CONCLUSIONS: Induction of labor at about 39 weeks is not associated with increased risk of cesarean delivery.

Expanded carrier screening: A current perspective.

Prenatal carrier screening has expanded to include a large number of genes offered to all couples considering pregnancy or with an ongoing pregnancy. Expanded carrier screening refers to identification of carriers of single-gene disorders outside of traditional screening guidelines. Expanded carrier screening panels include numerous autosomal recessive and X-linked genetic conditions, including those with a very low carrier frequency, as well as those with mild or incompletely penetrant phenotype. Therefore, the clinical utility of these panels is still subject of debate. Priority should be given to carrier screening panels that include a comprehensive set of severe childhood-onset disorders. Psychosocial support and genetic couseling should be available prior to screening and for the return of positive results. Systems are needed to reduce the risk of misinterpreting results. Finally, attention should be paid on the impact of expanded carrier screening on health care organizations and burden of cost.
