Background: The new SARS-CoV-2 originated from Wuhan, China is spreading rapidly worldwide. A number of SARS-CoV-2 positive pregnant women have been reported. However, more information is still needed on the pregnancy outcome and the neonates regarding COVID-19 pneumonia. Material and Methods: A systematic search was done and nine articles on COVID-19 pneumonia and SARS-CoV-2 positive pregnant women were extracted. Some maternal-fetal characteristics were extracted to be included in the meta-analysis. Results: The present meta-analysis was conducted on 87 SARS-CoV-2 positive pregnant women. Almost 65% of the patients reported a history of exposure to an infected person, 78% suffered from mild or moderate COVID-19, 99.9% had successful termination, 86% had cough, and 68% had fever (p ¼ .022 and p < .001). The overall proportions of vertical transmission, still birth, and neonatal death were zero, 0.002, and, 0.002, respectively (p ¼ 1, p ¼ .86, and p ¼ .89, respectively). The means of the first-and fifth-minute Apgar scores were 8.86 and 9, respectively (p < .001 for both). The confounding role of history of underlying diseases with an estimated overall proportion of 33% (p ¼ .03) resulted in further investigations due to sample size limitation. A natural history of COVID-19 pneumonia in the adult population was presented, as well. Conclusion: Currently, no evidence of vertical transmission has been suggested at least in late pregnancy. No hazards have been detected for fetuses or neonates. Although pregnant women are at an immunosuppressive state due to the physiological changes during pregnancy, most patients suffered from mild or moderate COVID-19 pneumonia with no pregnancy loss, proposing a similar pattern of the clinical characteristics of COVID-19 pneumonia to that of other adult populations.
Objective: This is the first comprehensive review to focus on currently available evidence regarding maternal, fetal and neonatal mortality cases associated with Coronavirus Disease 2019 (COVID-19) infection, up to July 2020. Methods: We systematically searched PubMed, Scopus, Google Scholar and Web of Science databases to identify any reported cases of maternal, fetal or neonatal mortality associated with COVID-19 infection. The references of relevant studies were also hand-searched. Results: Of 2815 studies screened, 10 studies reporting 37 maternal and 12 perinatal mortality cases (7 fetal demise and 5 neonatal death) were finally eligible for inclusion to this review. All maternal deaths were seen in women with previous co-morbidities, of which the most common were obesity, diabetes, asthma and advanced maternal age. Acute respiratory distress syndrome (ARDS) and severity of pneumonia were considered as the leading causes of all maternal mortalities, except for one case who died of thromboembolism during postpartum period. Fetal and neonatal mortalities were suggested to be a result of the severity of maternal infection or the prematurity, respectively. Interestingly, there was no evidence of vertical transmission or positive COVID-19 test result among expired neonates. Conclusion: Current available evidence suggested that maternal mortality mostly happened among women with previous co-morbidities and neonatal mortality seems to be a result of prematurity rather than infection. However, further reports are needed so that the magnitude of the maternal and perinatal mortality could be determined more precisely.
Background: The coronavirus disease of 2019 (COVID-19) pandemic has become the most challenging issue for healthcare organizations and governments all over the world. The lack of evidence-based data on the management of COVID-19 infection during pregnancy causes an additional stress for obstetrics healthcare providers (HCPs). Therefore, this study was undertaken to evaluate depression, perceived social support, and quality of life among obstetrics HCPs. Materials and Methods: This cross-sectional multicenter study was conducted in eight cities in Iran. During the study period, 599 HCPs were separated into direct, no direct, and unknown contact groups according to their exposure to COVID-19-infected pregnant patients. The Patient Health Questionaire-9 (PHQ-9), Multidimensional Scale of Perceived Social Support (MSPSS), and Short Form-36 (SF-36) were used to assess depression, perceived social support, and quality of life. Results: Obstetrics and gynecology specialists had significantly higher social functioning and general health scores compared to other HCPs (residents/students or nurses/midwives). Depression was negatively correlated with most of the domains of quality of life, regardless of the COVID-19 contact status of the study participants. Social support, however, was positively correlated with some domains of quality of life, such as physical functioning, energy/fatigue, and emotional well-being, among staff members who had either direct contact or no contact with COVID-19 patients. Conclusion: During the COVID-19 outbreak, the depression score among obstetrics HCPs was negatively associated with quality of life. Social support, however, had a reinforcing effect on quality of life.
Delivery is considered as one of the most painful experiences of women's life. The present study aimed to compare the effects of supportive care and acupressure on the pregnant women's pain intensity and delivery outcome. In this experimental study, 150 pregnant women were randomly divided into supportive care, acupressure, and control groups. The intensity of pain was measured using Visual Analogue Scale (VAS). The supportive care group received both physical and emotional cares. In the acupressure group, on the other hand, BL32 acupoint was pressed during the contractions. Then, the data were analyzed using descriptive and inferential statistics. The results revealed significant difference among the three groups regarding the intensity of pain after the intervention (P < 0.001). Besides, the highest rate of natural vaginal delivery was observed in the supportive care group (94%) and the acupressure group (92%), while the highest rate of cesarean delivery was related to the control group (40%) and the difference was statistically significant (P < 0.001). The results showed that maternal supportive care and acupressure during labor reduced the intensity of pain and improved the delivery outcomes. Therefore, these methods can be introduced to the medical team as effective strategies for decreasing delivery pain. This trial is registered with the Iranian Registry of Clinical Trial Code IRCT2014011011706N5.
Nowadays, acupuncture is widely used to manage pain, and childbirth is a condition requiring appropriate pain management interventions. The efficacy of acupuncture in the management of labor pain has recently been studied, but the results are not satisfactory and conflicts exist. In this study, we investigated the effects of acupuncture on labor pain, serum cortisol level, and duration of labor. We conducted a randomized, single-blind, controlled trial that included 63 nulliparous women: 32 in the study group and 31 in the control group. Acupuncture was performed at the SP-6 and the LI-4 points in the study group, and sham acupuncture was performed at the same points in the control group. Pain scores and serum cortisol levels were measured before and after the intervention. Changes in these measures and in the duration of labor were compared between the groups. No significant variations in pain scores or serum cortisol levels were observed between the two control groups. However, the duration of labor was significantly lower (p < 0.001) in the group receiving real acupuncture. Our results show that acupuncture is significantly associated with a decreased duration of labor, even though it was no better than a placebo for the treatment of labor pain.
Cigarette smoke is a complex mixture of toxic chemicals, including nicotine, carbon monoxide, and several recognized carcinogens and mutagens. Nicotine has a direct disturbing influence on steroid hormones (estrogen and progesterone), which are essential components of the female reproductive system, but the effect of nicotine on the hormone receptors is not yet clear. The aim of this study was to elucidate the effect of nicotine on the expression of estrogen receptor (ER), progesterone receptor (PR), and vascular endothelial growth factor (VEGF) in endometrial stromal cells. Expression levels of PR, ER, and VEGF in human endometrial stromal primary cells treated with nicotine (0, 10, 10, and 10μM) for 24 h were measured by quantitative real-time PCR. MTT assay demonstrated that nicotine decreased cell viability in a dose-dependent manner. Real-time PCR data showed that despite decrease in ER expression in the nicotine-treated groups compared with the control, nicotine exerted an increased inhibitory effect on PR expression compared to that on ER expression. VEGF mRNA expression in nicotine-treated endometrial stromal cells was increased. The results from this study provide novel evidence for inhibitory effects of nicotine on steroid hormones receptor expression in human primary endometrial cells. Also, our data suggest that nicotine might have angiogenesis effects on these cells.
Background and Objectives:Prolonged labor leads to increase of cesarean deliveries, reduction of fetal heart rate, and maternal as well as infantile complications. Therefore, many women tend to use pharmacological or non-pharmacological methods for reduction of labor length. The present study aimed to compare the effects of maternal supportive care and acupressure (at BL32 acupoint) on labor length and infant's Apgar score.Methods:In this clinical trial, 150 women with low-risk pregnancy were randomly divided into supportive care, acupressure, and control groups each containing 50 subjects. The data were collected using a questionnaire including demographic and pregnancy characteristics. Then, the data were analyzed using Chi-square test and one-way ANOVA.Results:The mean length of the first and second stages of labor was respectively 157.0±29.5 and 58.9±25.8 minutes in the supportive care group, 161.7±37.3 and 56.1±31.4 minutes in the acupressure group, ad 281.0±79.8 and 128.4±44.9 minutes in the control group. The difference between the length of labor stages was significant in the three study groups (P<0.001). Moreover, the frequency of Apgar score≥8 in the first and 5th minutes was higher in the supportive care and acupressure groups compared to the control group, and the difference was statistically significant (P<0.001).Conclusion:Continuous support and acupressure could reduce the length of labor stages and increase the infants’ Apgar scores. Therefore, these methods, as effective non-pharmacological strategies, can be introduced to the medical staff to improve the delivery outcomes.
