Risk factors associated with adverse fetal outcomes in pregnancies affected by Coronavirus disease 2019 (COVID-19): a secondary analysis of the WAPM study on COVID-19.

Objectives To evaluate the strength of association between maternal and pregnancy characteristics and the risk of adverse perinatal outcomes in pregnancies with laboratory confirmed COVID-19. Methods Secondary analysis of a multinational, cohort study on all consecutive pregnant women with laboratory-confirmed COVID-19 from February 1, 2020 to April 30, 2020 from 73 centers from 22 different countries. A confirmed case of COVID-19 was defined as a positive result on real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay of nasal and pharyngeal swab specimens. The primary outcome was a composite adverse fetal outcome, defined as the presence of either abortion (pregnancy loss before 22 weeks of gestations), stillbirth (intrauterine fetal death after 22 weeks of gestation), neonatal death (death of a live-born infant within the first 28 days of life), and perinatal death (either stillbirth or neonatal death). Logistic regression analysis was performed to evaluate parameters independently associated with the primary outcome. Logistic regression was reported as odds ratio (OR) with 95% confidence interval (CI). Results Mean gestational age at diagnosis was 30.6+/-9.5 weeks, with 8.0% of women being diagnosed in the first, 22.2% in the second and 69.8% in the third trimester of pregnancy. There were six miscarriage (2.3%), six intrauterine device (IUD) (2.3) and 5 (2.0%) neonatal deaths, with an overall rate of perinatal death of 4.2% (11/265), thus resulting into 17 cases experiencing and 226 not experiencing composite adverse fetal outcome. Neither stillbirths nor neonatal deaths had congenital anomalies found at antenatal or postnatal evaluation. Furthermore, none of the cases experiencing IUD had signs of impending demise at arterial or venous Doppler. Neonatal deaths were all considered as prematurity-related adverse events. Of the 250 live-born neonates, one (0.4%) was found positive at RT-PCR pharyngeal swabs performed after delivery. The mother was tested positive during the third trimester of pregnancy. The newborn was asymptomatic and had negative RT-PCR test after 14 days of life. At logistic regression analysis, gestational age at diagnosis (OR: 0.85, 95% CI 0.8-0.9 per week increase; pPeer reviewe

Maternal and perinatal outcomes of pregnant women with SARS-CoV-2 infection.

OBJECTIVES: To evaluate the maternal and perinatal outcomes of pregnancies affected by SARS-CoV-2 infection. METHODS: This was a multinational retrospective cohort study including women with a singleton pregnancy and laboratory-confirmed SARS-CoV-2 infection, conducted in 72 centers in 22 different countries in Europe, the USA, South America, Asia and Australia, between 1 February 2020 and 30 April 2020. Confirmed SARS-CoV-2 infection was defined as a positive result on real-time reverse-transcription polymerase chain reaction (RT-PCR) assay of nasopharyngeal swab specimens. The primary outcome was a composite measure of maternal mortality and morbidity, including admission to the intensive care unit (ICU), use of mechanical ventilation and death. RESULTS: In total, 388 women with a singleton pregnancy tested positive for SARS-CoV-2 on RT-PCR of a nasopharyngeal swab and were included in the study. Composite adverse maternal outcome was observed in 47/388 (12.1%) women; 43 (11.1%) women were admitted to the ICU, 36 (9.3%) required mechanical ventilation and three (0.8%) died. Of the 388 women included in the study, 122 (31.4%) were still pregnant at the time of data analysis. Among the other 266 women, six (19.4% of the 31 women with first-trimester infection) had miscarriage, three (1.1%) had termination of pregnancy, six (2.3%) had stillbirth and 251 (94.4%) delivered a liveborn infant. The rate of preterm birth before 37 weeks' gestation was 26.3% (70/266). Of the 251 liveborn infants, 69/251 (27.5%) were admitted to the neonatal ICU, and there were five (2.0%) neonatal deaths. The overall rate of perinatal death was 4.1% (11/266). Only one (1/251, 0.4%) infant, born to a mother who tested positive during the third trimester, was found to be positive for SARS-CoV-2 on RT-PCR. CONCLUSIONS: SARS-CoV-2 infection in pregnant women is associated with a 0.8% rate of maternal mortality, but an 11.1% rate of admission to the ICU. The risk of vertical transmission seems to be negligible. © 2020 International Society of Ultrasound in Obstetrics and Gynecology

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Ongoing pregnancies from early retrieval of prematurely developing antral follicles after DHEA supplementation

WOS: 000273671000009PubMed: 20031022Two patients with severely diminished ovarian reserve who were refractory to aggressive ovarian stimulation conceived with oocytes from prematurely developing antral follicles after dehydroepiandrosterone supplementation. The first patient had 11 and 14.5 mm, and the second patient had 13 mm antral follicles on cycle days 2 and 3 respectively. In the first case, no ovarian Stimulation was performed, while the second case received one dose of gonadotrophins with a gonadotrophin-releasing hormone antagonist. Following very early human chorionic gonadotrophin (HCG) triggering on cycle day 5, when antral follicles reached 15 and 18.5 mm in the first case, and 19 mm in the second case, IVF intracytoplasmic sperm injection treatment resulted in pregnancies in both cases, which are currently ongoing at 35 and 14 weeks of gestation. The results in these patients show that pregnancy can be achieved in poor responder patients with prematurely developing antral follicles following early HCG triggering based on follicle size rather than cycle day, with no or minimal stimulation. Whether DHEA Supplementation had any impact on the success of these cycles remains to be determined

Who is the best candidate for oocyte cryopreservation research?

WOS: 000273601200002PubMed: 18440517Clinical studies of oocyte cryopreservation have gained momentum within the recent years; however, no guidelines have yet been established for patient selection. This article discusses the controversial aspects of selecting candidates for oocyte cryopreservation research. (Fertil Steril(R) 2010;93:13-5. (C)2010 by American Society for Reproductive Medicine.

Age-specific probability of live birth with oocyte cryopreservation: an individual patient data meta-analysis

WOS: 000322633200039PubMed: 23706339Objective: To estimate age-specific probabilities of live birth with oocyte cryopreservation in nondonor (ND) egg cycles. Design: Individual patient data meta-analysis. Setting: Assisted reproduction centers. Patient(s): Infertile patients undergoing ND mature oocyte cryopreservation. Intervention(s): PubMed was searched for clinical studies on oocyte cryopreservation from January 1996 through July 2011. Randomized and nonrandomized studies that used ND frozen-thawed mature oocytes with pregnancy outcomes were included. Authors of eligible studies were contacted to obtain individual patient data. Main Outcome Measure(s): Live birth probabilities based on age, cryopreservation method, and the number of oocytes thawed, injected, or embryos transferred. Result(s): Original data from 10 studies including 2,265 cycles from 1,805 patients were obtained. Live birth success rates declined with age regardless of the freezing technique. Despite this age-induced compromise, live births continued to occur as late as ages 42 and 44 years with slowly frozen and vitrified oocytes, respectively. Estimated probabilities of live birth for vitrified oocytes were higher than those for slowly frozen. Conclusion(s): The live birth probabilities we calculated would enable more accurate counseling and informed decisions for infertile women considering oocyte cryopreservation. Given the success probabilities, we suggest that policy makers should consider oocyte freezing as an integral part of prevention and treatment of infertility.

Assessment of ovarian stromal artery Doppler characteristics and serum hormone levels in patients with Behcet disease

WOS: 000285038500007PubMed: 19821250PURPOSE The aim of the study was to examine serum hormone levels, ovarian volume, stromal artery Doppler parameters of patients with Behcet disease (BD) to assess whether there are vascular changes in the gonads of these patients. MATERIALS AND METHODS Twenty patients with BD and 31 healthy controls aged between 18-45 years were examined in the early follicular phase of the menstrual cycle (day 2-3) with transvaginal ultrasound to evaluate ovarian volume and ovarian stromal artery Doppler parameters. On the same day, blood was drawn for determining serum hormone levels. RESULTS Patients with BD and the controls were comparable with regard to age and body mass index at study inclusion. Although comparison of the ovarian stromal artery Doppler velocimetric parameters did not show significant differences, resistivity, pulsatility indexes and systolic/diastolic ratio were higher, while peak systolic and end diastolic velocities were lower, in BD patients compared to controls. The mean ovarian volume of patients with BD was smaller than the controls but this difference did not reach statistical significance. There were no statistically significant differences between serum hormone levels of either group. We did not find any correlations between hormone levels and mean ovarian stromal artery Doppler parameters of patients with BD. CONCLUSION Ovarian stromal artery Doppler parameters of patients with BD did not show any significant differences compared to healthy controls. Therefore, we conclude that ovarian stromal artery is not involved in patients with BD as assessed by transvaginal Doppler ultrasound and serum hormone levels do not differ from the levels of healthy controls

Breast cancer diagnosis following ovarian stimulation: Are the tumours different?

WOS: 000281172300016PubMed: 20615755Demographic data and tumour characteristics of 18 patients (study group) diagnosed with breast cancer within 24 months of undergoing ovarian stimulation with either gonadotrophins or clomiphene citrate were evaluated and compared with similar 102 age-matched women diagnosed with breast cancer without prior infertility treatment (control group). Eight out of 17 (47.1%) patients in the study group and 35/95 (36.8%) patients in the control group had positive family history for breast cancer. Median tumour size was similar in the study and control groups (both 1.3 cm). Both groups were comparable regarding tumour histological types and oestrogen receptor, progesterone receptor and Her2/Neu expression status. Albeit not significant, stage 0 tumours were more prevalent in the study group compared with the control group (22.2% versus 10.5%), and there were no stage III tumours in the study group as opposed to 7/95 in the control group. In conclusion, breast cancer diagnosed within the first 2 years following infertility treatment is similar in tumour characteristics compared with those occurring in patients without prior infertility treatment.

Diagnosis and management of vaginal mullerian cyst in a virgin patient

WOS: 000254751000023PubMed: 18008018Benign cystic lesions of the vagina are uncommon and may become symptomatic. We describe two symptomatic anterior vaginal wall cysts in a virgin patient and the usefulness of imaging modalities. A 36-year-old virgin woman presented with a complaint of vaginal bulging and pelvic pressure. Pelvic examination revealed a cystic mass protruding from the vagina surrounded by the intact hymen. The initial abdominopelvic ultrasound showed a hypoechoic cystic mass measuring 42 x 20 mm in the vagina. She then had a pelvic magnetic resonance imaging (MRI) that revealed two anterior vaginal wall cysts with no communication with the urethra or bladder. The cysts were excised and histologic examination with mucicarmine revealed mucin-secreting tall columnar cells consistent with a diagnosis of mullerian cyst. While both ultrasonographic examination and MRI are helpful in localizing vaginal cysts, MRI is superior in showing multiple cystic lesions of the vagina and their communication with the surrounding structures

Outcome of vasectomies performed at a Turkish metropolitan maternity hospital

WOS: 000246483100004PubMed: 17455040Objective To determine prospectively the outcome of vasectomies performed by two trained surgeons over a 9-month period at the Ministry of Health Ankara Etlik Maternity and Women's Health Teaching and Research Hospital Family Planning Centre. Methods The demographic data, source of information concerning the method, sexual function before and after voluntary no-scalpel vasectomy, compliance with the postvasectomy follow-up program of men applying for a vasectomy were analyzed. All patients were contacted by telephone and invited for follow-up visits for counseling, inquiry regarding sexual dysfunction, and performance of a semen analysis. Results The patients were married men, mostly primary school graduates, with more than one child. Sources of information were health services and/or health personnel for 89 0 of the patients. Of the 279 men who underwent a vasectomy and who were later contacted by phone, 131 (47%) came for a follow-up assessment. There was only one post-vasectomy pregnancy (0.8%). The incidence of reported sexual problems did not change after the procedure. Vasectomy did not affect the sexual function of men in our study. Conclusion Compliance with follow-up after vasectomy, which is extremely important for assessment of its successful outcome, is low
