Impact of COVID-19 on maternal and neonatal outcomes: a systematic review and meta-analysis.

BACKGROUND: Previous outbreaks of severe acute respiratory syndrome coronavirus 1 (SARS-CoV-1) and Middle East respiratory syndrome coronavirus (MERS-CoV) have been associated with unfavourable pregnancy outcomes. SARS-CoV-2 belongs to the human coronavirus family, and since this infection shows a pandemic trend it will involve many pregnant women. AIMS: This systematic review and meta-analysis aimed to assess the impact of coronavirus disease 19 (COVID-19) on maternal and neonatal outcomes. SOURCES: PubMed, EMBASE, MedRxiv, Scholar, Scopus, and Web of Science databases were searched up to 8th May 2020. Articles focusing on pregnancy and perinatal outcomes of COVID-19 were eligible. Participants were pregnant women with COVID-19. CONTENT: The meta-analysis was conducted following the PRISMA and MOOSE reporting guidelines. Bias risk was assessed using the Joanna Briggs Institute (JBI) manual. The protocol was registered with PROSPERO (CRD42042020184752). Twenty-four articles, including 1100 pregnancies, were selected. The pooled prevalence of pneumonia was 89% (95%CI 70-100), while the prevalence of women admitted to the intensive care unit was 8% (95%CI 1-20). Three stillbirths and five maternal deaths were reported. A pooled prevalence of 85% (95%CI 72-94) was observed for caesarean deliveries. There were three neonatal deaths. The prevalence of COVID-19-related admission to the neonatal intensive care unit was 2% (95%CI 0-6). Nineteen out of 444 neonates were positive for SARS-CoV-2 RNA at birth. Elevated levels of IgM and IgG Serum antibodies were reported in one case, but negative swab. IMPLICATIONS: Although adverse outcomes such as ICU admission or patient death can occur, the clinical course of COVID-19 in most women is not severe, and the infection does not significantly influence the pregnancy. A high caesarean delivery rate is reported, but there is no clinical evidence supporting this mode of delivery. Indeed, in most cases the disease does not threaten the mother, and vertical transmission has not been clearly demonstrated. Therefore, COVID-19 should not be considered as an indication for elective caesarean section.

Meconium-stained amniotic fluid: a risk factor for postpartum hemorrhage.

BACKGROUND/AIM: Clinical data with respect to the impact of meconium on the risk of maternal hemorrhage are scarce. Therefore, in this study, we aimed to determine whether meconium-stained amniotic fluid (MSAF) represents a risk factor for postpartum hemorrhage (PPH) after vaginal delivery in a large unselected population. PATIENTS AND METHODS: A retrospective cohort study evaluated 78,542 consecutive women who had a vaginal delivery between 24th and 44th weeks of gestation. The women who had undergone cesarean section were excluded to avoid possible bias. Postpartum blood loss was measured with graduated blood sack. Postpartum blood loss between 1,000 and 2,000 mL and >2,000 mL were classified as moderate and severe PPH, respectively. RESULTS: A total of 74,144 patients were available for analysis. According to the color of amniotic fluid (AF), two groups of patients were identified: MSAF (n=10,997) and clear AF (n=63,147). The rates of severe and massive PPH were found to be significantly higher in the MSAF group than that of clear AF group (OR=1.3, 95% CI: 1.2-1.5, p<0.001 and OR=2.5, 95% CI: 1.5-4.2, p<0.001). Operative vaginal delivery rate was found to be higher in the MSAF group than that of clear AF group, but the difference was only borderline significant (OR=1.5, 95% CI: 1.0-2.2, p=0.05). There were no significant differences between the MSAF and the clear AF groups with respect to episiotomies, second- or third-degree perineal tears, vaginal-perineal thrombus, cervical lacerations, vaginal births after cesarean section, twin deliveries, and placental retention rates. CONCLUSION: To the best of our knowledge, this is the first clinical study that has investigated the role of MSAF as a risk factor for PPH after vaginal delivery in an unselected population. Our results suggest that MSAF is significantly associated with higher risk of moderate and severe PPH than clear AF.

Hysteroscopic chasing for endometrial cancer in a low-risk population: risks of overinvestigation.

PURPOSE: To evaluate the appropriateness of the indications for hysteroscopy done, in fertile and postmenopausal women, for the detection of endometrial cancer. METHODS: A retrospective analysis of 2673 consecutive women who underwent office hysteroscopy chasing for endometrial cancer between January 2012 and June 2014. According to their medical history only low-risk women entered the study. RESULTS: A total of 1070 patients entered the study. The main outcome measure was the appropriateness of the indications for hysteroscopy. Appropriateness was assessed on the basis of guidelines of scientific societies and histologic report. According to the algorithm developed for appropriateness, 44 % of procedures resulted in being inappropriate. In reproductive-aged women 57 % of hysteroscopies were inappropriate. In postmenopausal women inappropriate hysteroscopies were 45 %. In reproductive-aged women, the reasons for inappropriateness were: absence of abnormal uterine bleeding (AUB) or AUB without a trial of progestin therapy. In postmenopausal women, the reasons for inappropriateness were: ultrasound report of endometrial thickening or polyp without bleeding. CONCLUSIONS: Hysteroscopy is often recommended for inappropriate indications. More evidence is needed to identify the risks of overinvestigation, overdiagnosis, and related overtreatment and to better identify the threshold beyond which benefits are likely to outweigh harms.

"GINEXMAL RCT: Induction of labour versus expectant management in gestational diabetes pregnancies".

BACKGROUND: Gestational diabetes (GDM) is one of the most common complications of pregnancies affecting around 7% of women. This clinical condition is associated with an increased risk of developing fetal macrosomia and is related to a higher incidence of caesarean section in comparison to the general population. Strong evidence indicating the best management between induction of labour at term and expectant monitoring are missing. METHODS/DESIGN: Pregnant women with singleton pregnancy in vertex presentation previously diagnosed with gestational diabetes will be asked to participate in a multicenter open-label randomized controlled trial between 38+0 and 39+0 gestational weeks. Women will be recruited in the third trimester in the outpatient clinic or in the Day Assessment Unit according to local protocols. Women who opt to take part will be randomized according to induction of labour or expectant management for spontaneous delivery. Patients allocated to the induction group will be admitted to the obstetric ward and offered induction of labour via use of prostaglandins, Foley catheter or oxytocin (depending on clinical conditions). Women assigned to the expectant arm will be sent to their domicile where they will be followed up until delivery, through maternal and fetal wellbeing monitoring twice weekly. The primary study outcome is the Caesarean section (C-section) rate, whilst secondary measurements are maternal and neonatal outcomes. A total sample of 1760 women (880 each arm) will be recruited to identify a relative difference between the two arms equal to 20% in favour of induction, with concerns to C-section rate. Data will be collected until mothers and newborns discharge from the hospital. Analysis of the outcome measures will be carried out by intention to treat. DISCUSSION: The present trial will provide evidence as to whether or not, in women affected by gestational diabetes, induction of labour between 38+0 and 39+0 weeks is an effective management to ameliorate maternal and neonatal outcomes. The primary objective is to determine whether caesarean section rate could be reduced among women undergoing induction of labour, in comparison to patients allocated to expectant monitoring. The secondary objective consists of the assessment and comparison of maternal and neonatal outcomes in the two study arms. .

Tubercular endometritis visualized as endometrial micropolyps during hysteroscopic procedure.

Female genital tuberculosis is a rare disease in developed countries but it is a frequent cause of chronic pelvic inflammatory disease and infertility in undeveloped countries. A rare case of tubercular endometritis diagnosed at hysteroscopy and successfully treated in a woman with secondary infertility, is presented. As far as we know this is the first case that shows the association between endometrial micropolyps and tubercular endometritis.

Resectoscopic treatment of atypical endometrial polyps in fertile women.

OBJECTIVE: The purpose of this study was to evaluate the long-term efficacy and prognosis of hysteroscopic resection and coagulation of the base of endometrial polyps with focal atypia in fertile women with or without progestin suppression. STUDY DESIGN: We conducted a quasi-randomized trial in which conservative treatment was offered to 21 patients who had endometrial polyps with focal atypia and a surrounding normal endometrium. The polyps were analyzed separately from their bases. Random biopsy specimens were taken from 4 standard places of the endometrium. RESULTS: Eighteen women (10 women with an intrauterine device and 8 women with no intrauterine device) completed the follow-up procedure. After 5 years, we found no difference in the 2 groups regarding recurrence of atypical polyps. CONCLUSION: Conservative resectoscopic treatment may be considered in fertile women with atypical polyps if polyp base and surrounding endometrium are benign. If women want to become pregnant at short term, the use of progestins can be delayed, with a strict follow-up procedure. Larger studies should be encouraged.

Is resectoscopic treatment of atypical endometrial polyps a safe option?

OBJECTIVE: This study was undertaken to evaluate the long-term efficacy and prognosis of hysteroscopic resection and coagulation of the polyp base of endometrial polyps with focal atypia in postmenopausal women. STUDY DESIGN: In this observational noncomparative study, conservative treatment was offered to 16 patients, with high anesthesiologic risk, who had endometrial polyps with focal atypia and a surrounding atrophic endometrium. To confirm the focality of the lesion, the polyps were analyzed separately from their bases. Patients with atypia in the polyp base were excluded. RESULTS: After 5 years of follow-up, 13 patients are disease free, 2 underwent vaginal hysterectomy and annessiectomy due to other causes, and 1 died for cardiac disorders. CONCLUSION: Adenomatous polyps with atypia can be treated resectoscopically if the treatment is associated with an accurate histologic examination of the polyp base and its eventual involvement and the features of the remaining uterine mucosa. A thorough follow-up is recommended. Studies on wider casuistries of patients are needed.
