RESUMO

OBJECTIVE: Pregnancy is a unique challenge for the immune system. Any disturbance in the immune system in the first trimester could result in further pregnancy complications. In this regard, the current study aimed to investigate the association between serum levels of a group of cytokines in the first trimester of pregnancy with the onset of preeclampsia (PE) and fetal growth restriction (FGR). MATERIALS AND METHODS: Serum samples were collected from 550 pregnant women at their 11th - 13th weeks of pregnancy and followed up to delivery. Out of all cases, 15 women complicated with preeclampsia and 15 ones diagnosed with FGR were included in the study. The serum levels of IFN-γ, CCL2, IL-10, IL-35 and IL-27 were checked in the collected sera of mentioned patients and compared to 60 women with normal pregnancy outcomes. RESULTS: In the preeclampsia group, the mean level of IFN-γ was significantly higher (p < 0.001) while the CCL2 serum level was significantly lower (p < 0.003) as compared to control group. There was no significant difference between the preeclampsia group and controls regarding other cytokines. In the FGR group, the mean serum level of IFN-γ was significantly higher compared to the healthy pregnancy group (p < 0.001) but other cytokines showed no significant differences. In the FGR group, a significant positive correlation was found between IL-10 level and neonates' weight (p < 0.05). CONCLUSION: Based on the results of the present study, an elevated level of IFN-γ and a reduced level of CCL2 at the first trimester of pregnancy could lead to complications such as PE and/or FGR.

RESUMO

OBJECTIVE: Management of pregnancy complicated by severe early-onset fetal growth restriction (FGR) is one of the most challenging obstetrical issues. So far, there has not been a proven option for the treatment or improvement of this condition. Improper immune response during placentation leads to inadequate trophoblast invasion and impaired utero-placental perfusion. Pentoxifylline improves the endothelial function and induces vasodilation by reducing the inflammatory-mediated cytokines. We have evaluated the effect of Pentoxifylline on fetal-placental perfusion, neonatal outcome, and the level of oxidative stress markers before and after the intervention in the setting of severe early-onset FGR. MATERIALS AND METHODS: This study is a pilot randomized clinical trial on 40 pregnant women who had developed early-onset growth restricted fetus. Pentoxifylline and placebo were given with a dose of 400 mg per os two times daily until delivery. Serial ultrasound examination regarding fetal weight, amniotic fluid and also utero-placenta-fetal Doppler's were done. For the assessment of serum Antioxidant level, blood sampling was done once at the beginning of the study and again, at least, three weeks after the investigation. After delivery, umbilical-cord blood gas analysis, APGAR score at 1 and 5 min, NICU admission, and neonatal death were recorded and compared between the two groups. RESULTS: Utero-placenta-fetal Doppler's in the Pentoxifylline group did not significantly change compared to the control group. Fetal weight gain was significantly higher in the Pentoxifylline group before (996.33 ± 317.41) and after (1616.89 ± 527.90) treatment (P = 0.002). Total serum antioxidant capacity significantly increased in the Pentoxifylline group (p < 0.036). Average 5 min Apgar score was significantly higher (P < 0.036) and the percentage of babies admitted to NICU was significantly lower (P < 0.030) in the treated group. CONCLUSION: Using Pentoxifylline in pregnancy affected by FGR might show promising effects. In this study, Pentoxifylline improved the neonatal outcome, increased fetal weight gain, and reduced neonatal mortality by decreasing the level of oxidative stress markers and cutting down the inflammatory cascade.

RESUMO

OBJECTIVES: Preterm birth (PTB) is the common cause of neonatal mortality nationwide. The present study aimed to evaluate the efficacy of different doses of aspirin in preventing PTB in high-risk pregnant women. As secondary outcomes, other perinatal complications were compared. METHODS: This double-blind randomized clinical trial was conducted on high-risk pregnant women with impaired placental perfusion diagnosed in the first trimester of pregnancy referring to the perinatal centers affiliated to Shiraz university of Medical Sciences between February 2020 and March 2021. The subjects were randomly divided in two groups administered with 150 or 80 mg aspirin every night from 11 to 13+6 weeks until 36 weeks or delivery. This study is registered in the Iranian Registry of Clinical Trials (IRCT20140317017035N6; http://www.irct.ir/). Univariate and multiple logistic regressions were applied using SPSS 22. RESULTS: A total of 101 subjects received 80 mg aspirin and 89 ones received 150 mg aspirin. The results of multiple analysis revealed a significantly lower odds of PTB (OR 0.4 (0.19, 0.99)) in the 150 mg group compared to the 80 mg group. As secondary outcomes, preeclampsia (PEC) and PEC with severe features (PECsf) were lower (OR 0.2 (0.06, 0.82) and 0.1 (0.01, 0.92), respectively); however, fetal age and neonatal weight were higher in the 150 mg group (OR 1.2 (1.04, 1.33) and 1.001 (1-1.001), respectively). CONCLUSIONS: The study findings indicated that, compared with 80 mg of aspirin, taking 150 mg of aspirin reduced PTB and perinatal complications in high risk pregnant women.

RESUMO

BACKGROUND: Natural delivery is distressing, and the mother's anxiety in this condition can have negative impacts on the fetus, mother, and the delivery process. Hence, many women tend to use pharmacological or nonpharmacological methods for reduction of labor stress and anxiety. The aim was to assess the effect of supportive care and acupressure during labor on the mother's anxiety level and arterial oxygen pressure of the umbilical cord of infants. MATERIALS AND METHODS: This performed on 150 pregnant women were randomly assigned to two interventions and a control group in the delivery ward of the selected educational center of Shiraz University of Medical Sciences (Shoushtari Hospital) in Iran. Mothers' anxiety scores before (beginning of the active stage of labor) and after intervention (the end of the first stage of labor) were measured using Spielberger's questionnaire. Then, infants' cord blood samples for arterial blood gas and hematologic analyses were sent to the hospital's laboratory. After all, the data with SPSS version 16 and using Pearson's correlation coefficient, one-way ANOVA, were analyzed. RESULTS: The mean of anxiety score in the control group was 21.1% and in the supportive group and the acupressure group, respectively, decreased by 37.5% and 34.8%, respectively (P < 0.001). The mean of PO2 was also reported in the maternal supportive, acupressure, and control groups, 40.4 ± 8.8, 27.4 ± 2.8, and 18.1 ± 3.7, respectively. Additionally, a significant correlation was found between mothers' anxiety scores after the intervention and the mean of PO2 (P = 0.014). CONCLUSION: The supportive care and acupressure at BL32 acupoint reduced mothers' anxiety and consequently improved fetal oxygenation. Therefore, these methods are recommended to be used during labor for improving birth outcomes.

RESUMO

AIM: To compare the success rate of vaginal misoprostol versus intravenous (IV) oxytocin in termination of pregnancy in the second trimester intrauterine fetal death (IUFD). METHODS: This was an open-label randomized controlled study for 106 women with second trimester IUFD. Patients were randomly divided into two groups: women given vaginal misoprostol (400 mcg every 6 h up to 48 h) versus those given IV oxytocin (starting with 50 units up to a maximum of 300 units). When the first-line treatment (as mentioned above) failed, treatment methods were replaced with each other. When the second-line treatment failed, the patients underwent dilation and evacuation. RESULTS: The first-line treatment yielded the successful rate of 88.7% versus 73.7% for misoprostol versus oxytocin, respectively (p = 0.047). Among those with first-line treatment failure, the second-line treatment yielded success rate of 85.7% versus 83.3% for misoprostol versus oxytocin (p = 0.891). The mean duration of induction to delivery in women with successful response to first-line treatment was 28.72 and 20.55 h after initially receiving misoprostol versus oxytocin, respectively (p < 0.001). While during second-line treatment, this mean interval was not significantly different among those with misoprostol versus oxytocin (p = 0.128). No severe adverse events were observed. CONCLUSION: Vaginal misoprostol was associated with higher termination rate than oxytocin without adverse events when used as the first-line treatment. Both methods yielded the same success rate when used as the second-line treatment.

RESUMO

OBJECTIVE: ß-thalassemia is a prevalent disease in Iran. The adverse effects of anemia on placental and neonatal outcomes have previously been shown. Women require additional iron during pregnancy and the anemia of women with ß-thalassemia may adversely affect the neonatal outcome and increase placental abnormalities. In this study, we compared the placental histology and neonatal outcomes among pregnant women with and without ß-thalassemia. MATERIAL AND METHODS: In this population-based cross-sectional study, 144 pregnant women with ß-thalassemia minor (case group) were compared to 142 women without ß-thalassemia (control group). Women with singleton pregnancies over 20 weeks of gestation without pregnancy complications, anemia, collagen vascular diseases, or other hemoglobinopathies, all referred to hospitals affiliated to Shiraz University of Medical Sciences from March 2014 to February 2016, were included and maternal and neonatal data were extracted from medical records. After child birth, the placenta was evaluated for macroscopic and microscopic changes. RESULTS: The frequency of LBW was significantly higher in the case group than that in the control group (19.7 vs. 9.7%, respectively) (p = .019). Six in the case group had gross abnormalities of placenta, while none in the control group (p = .03) and the case group had a higher frequency of chorangiosis, calcification, syncytial knot, and umbilical cord position (p < .05). CONCLUSION: As ß-thalassemia increases the chance of placental abnormalities, it is recommended to pay more attention to patients with ß-thalassemia, especially during pregnancy, to prevent placental and neonatal adverse outcomes.

RESUMO

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.

RESUMO

BACKGROUND: The efficacy of maintenance tocolytic therapy after successful arrest of preterm labor remains controversial. The purpose of this study was to evaluate the efficacy of 400 mg of daily vaginal progesterone (cyclogest) after successful parenteral tocolysis to increase latency period and improvement of neonatal outcomes in women with threatened preterm labor. MATERIALS AND METHODS: In this randomized, double-blind, placebo-controlled trial, 85 participants were randomly allocated to either 400 mg daily of vaginal progesterone (n = 45) or placebo (n = 40) until 34 weeks of gestation. The primary outcomes were the time until delivery (latency period) and cervical length after 1 week of treatment. Secondary outcome were GA on delivery, type of delivery, incidence of low birth weight, perinatal morbidity and mortality. RESULTS: Longer mean latency until delivery (53.6 ± 16.8 versus 34.5 ± 12.9) days p = .0001; longer mean of gestational age on delivery (37.5 ± 2.2 versus 34.2 ± 2.1) weeks p = .0001; cervical length after 1 week of treatment (27.5 ± 5.5 versus 20.7 ± 3.1) mm p = .0001; low birth weight 12 (29.3%) versus 19 (57.6%) p = .01; and NICU admission 9 (22%) versus 15 (45.5%), were significantly different between the two groups. No significant differences were found between neonatal death 1 (2.4%) versus 2 (6.1%), p = .43; RDS 5 (12.2%) versus 8 (24.2%), p = .17; and need to mechanical ventilator 2 (5.4%) versus 6 (18.2%) p = .136, for the progesterone and placebo groups, respectively. CONCLUSION: Daily administration of 400 mg vaginal progesterone after successful parenteral tocolysis may increase latency preceding delivery and improves cervical shortening and neonatal outcome in women with preterm labor. Further confirmatory studies are warranted.

RESUMO

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 = .022 and p < .001). The overall proportions of vertical transmission, still birth, and neonatal death were zero, 0.002, and, 0.002, respectively (p = 1, p = .86, and p = .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 = .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.

RESUMO

This study aimed to assess the maternal features, Vascular Endothelial Growth Factor (VEGF) and Placenta Growth Factor (PLGF) in the Placenta Accreta Spectrum (PAS); then, to determine a predictive value of VEGF and PLGF in the PAS. This prospective case-control study was conducted on 90 pregnant women including 45 PAS, and 45 Normal Placenta (NP). Maternal age, gravidity, C/S, and serum levels of VEGF and PLGF were assessed between NP and PAS, and among NP and PAS sub-groups, including Placenta Accreta (PA), Placenta Increta (PI), and Placenta Percreta (PP). The Multi-gravidity, previous C/S, maternal age, and serum level of PLGF were significantly higher in the PAS group compared to the NP group OR = 42, 8.1, 1.17, and 1.002 (p-value <.05 for all); however, there was no difference regarding serum level of VEGF (p-value >.05). The same differences were seen among NP with PA, PI, and PP sub-groups (p-value <.05 for all, but p-value >.05 for VEGF). Placenta Previa was uniformly distributed across the PAS sub-groups (p-value >.05), also the VEGF and PLGF serum levels did not differ between PAS with Previa and PAS without Previa groups (p-value >.05). A valid cut-off point for PLGF was reported at 63.55. A predictive value of PLGF for the PAS patients is presented enjoying high accuracy and generalisability for the study population.Impact statementWhat is already known on this subject? The Placenta Accreta Spectrum (PAS), in which the placenta grows too deep in the uterine wall, is responsible for maternal-foetal morbidity and mortality worldwide; so, the antenatal diagnosis of PAS is an important key to improve maternal-foetal health. Normal placental implantation requires a fine balance among the levels of angiogenic and anti-angiogenic factors, such as the Placenta Growth Factor (PLGF), the Vascular Endothelial Growth Factor (VEGF), and soluble Fms-like tyrosine kinase-1. However, there is still controversy regarding The PLGF and VEGF level changes in PAS patients.What do the results of this study add? Despite traditional measuring the levels of PLGF and VEGF from the placenta at the time of delivery; in this study including 90 participants (28-34 weeks of gestation) the maternal serum levels of PLGF and VEGF were measured in advance (temporality causation), resulted in presenting a more valid cut-off point for PLGF in PAS group. In addition, the serum level of PLGF was significantly higher in the PAS and PAS sub-groups compared to the Normal Placenta group. Also, the Previa status of PAS patients did not affect the VEGF and PLGF serum levels.What are the implications of these findings for clinical practice and/or further research? PLGF cut-off point derived from the maternal serum level could predict PAS validly and, if used as a screening test in an earlier pregnancy, the maternal-foetal morbidity and mortality would decrease.

RESUMO

BACKGROUND: We aimed to investigate the risk factors of placenta accreta spectrum (PAS) disorder, management options and maternal and neonatal outcomes of these pregnancies in a resource-limited clinical setting. METHODS: All women diagnosed with placenta accreta, increta, and percreta who underwent peripartum hysterectomy using a multidisciplinary approach in a tertiary center in Shiraz, southern Iran between January 2015 until October 2019 were included in this retrospective cohort study. Maternal variables, such as estimated blood loss, transfusion requirements and ICU admission, as well as neonatal variables such as, Apgar score, NICU admission and birthweight, were among the primary outcomes of this study. RESULTS: A total number of 198 pregnancies underwent peripartum hysterectomy due to PAS during the study period, of whom163 pregnancies had antenatal diagnosis of PAS. The mean gestational age at the time of diagnosis was 26 weeks, the mean intra-operative blood loss was 2446 ml, and an average of 2 packs of red blood cells were transfused intra-operatively. Fifteen percent of women had surgical complications with bladder injuries being the most common complication. Furthermore, 113 neonates of PAS group were admitted to NICU due to prematurity of which 15 (7.6%) died in neonatal period. CONCLUSION: Our findings showed that PAS pregnancies managed in a resource-limited setting in Southern Iran have both maternal and neonatal outcomes comparable to those in developed countries, which is hypothesized to be due to high rate of antenatal diagnosis (86.3%) and multidisciplinary approach used for the management of pregnancies with PAS.

RESUMO

BACKGROUND: Prenatal corticosteroid administration is known to be an effective strategy in improving fetal pulmonary maturity. This study aimed to evaluate the impact of maternal betamethasone administration on fetal pulmonary and other arteries Doppler velocity and the correlation between RDS development and Doppler indices results. METHODS: Fifty one singleton pregnancies between 26 and 34 gestational weeks with a diagnosis of preterm labor were included in the exposed group and received betamethasone. Fifty one uncomplicated pregnancies were included in the non-exposed group. Fetal pulmonary, umbilical and middle cerebral arteries Doppler parameters were evaluated before and 24 to 48 h after steroid administration in the exposed group and two times at same intervals in the non-exposed group. Maternal records were matched to neonatal charts if delivery happened, and demographic and outcome data were abstracted. RESULTS: When compared with the nonexposed group, fetuses treated with corticosteroids demonstrated significantly decreased umbilical artery Pulsatility index (PI) and significantly increased the middle cerebral artery PI, pulmonary artery Acceleration time (AT) and pulmonary artery AT/ET (Ejection time), while all other indices remained similar. We found significantly decreased pulmonary artery AT in the fetuses with respiratory distress syndrome (RDS) compared to those that did not. CONCLUSIONS: The results of our study showed that maternal antenatal betamethasone administration caused significant changes in the fetus blood velocity waveforms and also affected the blood flow in the pulmonary artery which led to an increase in the pulmonary artery AT and AT/ET. Among those fetuses with RDS, we found a significant decrease in the pulmonary artery AT, but we did not observe any pulmonary artery AT/ET differences.

RESUMO

OBJECTIVE: Considering the role of oxidative stress in the development and progression of endometriosis, the ameliorative effect of caffeic acid treatment on ectopic, eutopic endometrial cells enzyme activities was investigated. We also determined the underlying cellular mechanisms. MATERIALS AND METHODS: Ectopic endometrial specimens were collected from women with confirmed cases of endometriosis (n = 10) and eutopic specimens from (n = 10) controls. Following endometrial cell isolation and culture, eutopic and ectopic endometrial cells were treated with caffeic acid. Then, reactive oxygen species (ROS) level, NAD(P)H quinone oxidoreductase 1 (NQO1), and Heme oxygenase 1 (HO-1) enzyme activities, nuclear factor erythroid 2-related factor 2 (Nrf-2) gene expression were measured. RESULTS: In ectopic endometrial cells, caffeic acid caused a significant elevation in Nrf-2 gene expression level, NQO1, and HO-1 enzyme activities. In addition, reduced ROS level was observed in caffeic acid-treated ectopic endometrial cells in comparison with the control. On the contrary, we did not observe any significant changes in caffeic acid-treated eutopic endometrial ones. CONCLUSION: Caffeic acid can protect the endometrial cells against oxidative stress and might be able to prevent the progression of endometriosis and its related complications, such as pain and infertility.

RESUMO

The alteration of the uterocervical angle (UCA) has been proposed to play an important role in spontaneous preterm birth (sPTB). The aim of this systematic review and meta-analysis was to evaluate the evidence on the UCA predictive role in sPTB. In this study, PubMed, Web of Science, Scopus, and Google scholar were systematically searched from inception up to June 2020. Inter-study heterogeneity was also assessed using Cochrane's Q test and the I2 statistic. Afterward, the random-effects model was used to pool the weighted mean differences (WMDs) and the corresponding 95% confidence intervals (CIs). Eleven articles that reported second-trimester UCA of 5,061 pregnancies were included in this study. Our meta-analysis results indicate that a wider UCA significantly increases the risk of sPTB in following cases: all pregnancies (WMD = 15.25, 95% CI: 11.78-18.72, p < 0.001; I2 = 75.9%, p < 0.001), singleton (WMD = 14.43, 95% CI: 8.79-20.06, p < 0.001; I2 = 82.4%, p < 0.001), and twin pregnancies (WMD = 15.14, 95% CI: 13.42-16.87, p < 0.001; I2 = 0.0%, p = 0.464). A wider ultrasound-measured UCA in the second trimester seems to be associated with the increased risk of sPTB in both singleton and twin pregnancies, which reinforces the clinical evidence that UCA has the potential to be used as a predictive marker of sPTB.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional Persian medicine manuscripts refer to plants such as Commiphora myrrha (Nees) Engl. (myrrh) and Boswellia carteri Birdw. (frankincense), which could be used to improve wound healing process. Since that time, local midwives in Iran continue to provide these herbs to precipitate episiotomy wound healing. AIM OF THE STUDY: To investigate the efficacy and safety of myrrh- and frankincense-based sitz-baths on episiotomy wound healing in primiparous women. MATERIALS AND METHODS: This randomized controlled trial was conducted on 90 primiparous women with singleton pregnancies after normal vaginal delivery at Hafez hospital affiliated to Shiraz University of Medical Sciences from July to October 2019. Study participants were randomly allocated in three groups (2 intervention groups and 1 control group). Women in intervention groups were assigned to receive either 10-min sitz-bath of myrrh extract or frankincense extract twice a day for 1 week. While the women in control group received the betadine sitz-bath for the same period of time. The main outcome was the episiotomy wound healing, which was measured using the REEDA scale before intervention, on 2nd and 7th postpartum days. RESULTS: An improvement in the episiotomy wound healing was significantly greater in patients receiving myrrh than those receiving the frankincense or betadine on 2nd (p = 0.003 and p < 0.001) and 7th (p = 0.043 and p = 0.015) postpartum days. However, the total REEDA score was not statistically different between the frankincense and betadine groups on 2nd and 7th postpartum days (p > 0.05). CONCLUSION: The present results suggest that myrrh was more efficient than frankincense and betadine in healing of the episiotomy wound and could be recommended as a safe natural therapy.

RESUMO

BACKGROUND: Animals can play an important role in preparing tissues for human through the development of xenotransplantation protocols. The most common problem with liver transplantation like any other organ transplantation is organ supply shortage. OBJECTIVE: To evaluate the in utero xenotransplantation of mouse bone marrow-derived stromal/stem cells (BMSCs) to the liver of rat fetus to produce mouse liver tissue. MATERIALS AND METHODS: BMSCs were isolated and confirmed from enhanced green fluorescent protein (eGFP)-genetic labeled mice. Using a microinjection protocol, mice BMSCs were injected into the liver of rat fetuses in utero on day 14 of pregnancy. After birth, livers were collected and the presence of mice eGFP-positive cells in rat livers was evaluated through polymerase chain reaction. RESULTS: The eGFP mRNA was detected in the liver of injected infant rats. BMSCs of adult mice were capable to remain functional probably as hepatocyte-like cells in liver of infant rats after in utero xenotransplantation. CONCLUSION: BMSCs have the potential for intrauterine xenotransplantation for the treatment of liver dysfunction before birth. This method can also be used for xenoproduction of liver tissue for transplantation.

RESUMO

BACKGROUND: Due to the significance of preeclampsia (PE) and its adverse outcomes in the health of both mother and newborn, the present study was carried out to investigate the effect of aspirin on preventing the occurrence of PE, intrauterine growth restriction (IUGR), and preterm delivery in women with a previous history of PE. METHODS: The present clinical trial was conducted on 90 pregnant women with a previous history of PE referred to the Khalij Fars Hospital in Bandar Abbas, Hormozgan Province Iran from April 2017 to August 2018. The subjects of the study were randomly assigned into two groups of intervention and control to receive either 80 mg of aspirin or placebo daily during the pregnancy. Patients' information was obtained and recorded upon entering the study, follow-up visits, and childbirth. RESULTS: Among participants who entered the clinical trial, 86 patients (95.6%) completed the study. During the pregnancy, systolic blood pressure increased by 8.25 ± 14.83 and 19.06 ± 18.33 mmHg in aspirin and placebo groups, respectively (p = 0.001). Also, the same happened with diastolic blood pressure (6.12 ± 11.46 vs 13.48 ± 13.95 mmHg, p = 0.010). The rate of PE was equal to 27 (62.8%) and 38 (88.4%) in the aspirin and placebo groups, respectively (aOR = 0.23, p = 0.013). In the aspirin group, the rate of IUGR was equal to 27.9% compared with 25.6% of newborns in the control group (aOR = 1.18, p = 0.750). Similarly, there was no significant difference in the rate of preterm delivery between the two groups (p = 0.061). CONCLUSION: The findings of the present study conducted exclusively on women with previous documented PE revealed that taking aspirin may have a preventive effect on PE in the current pregnancy.

RESUMO

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.

RESUMO

Cervical cancer is among the most common causes of cancer-related deaths in low- and middle-income countries (LMICs). Despite the strong evidence regarding cervical cancer screening cost-effectiveness, its utilization remains low especially in high risk populations such as HIV-positive women. The aim of this review was to provide an overview on the patient-reported factors influencing cervical cancer screening uptake among HIV-positive women living in LMICs. We systematically searched EMBASE, PUBMED/MEDLINE and Web of Science databases to identify all quantitative and qualitative studies investigating the patient-reported barriers or facilitators to cervical cancer screening uptake among HIV-positive population from LMICs. A total of 32 studies met the inclusion criteria. A large number of barriers/facilitators were identified and then grouped into three categories of personal, social and structural variables. However, the most common influential factors include knowledge and attitude toward cervical cancer or its screening, embarrassment, fear of cervical cancer screening and test results, patient-healthcare provider relationship, social support, screening costs and time constraints. This review's findings highlighted the need for multi-level participation of policy makers, health professionals, patients and their families in order to overcome the barriers to uptake of cervical cancer screening among HIV-positive women, who are of special concern in LMICs.
