Majority of the recipients of these treatments are women within the reproductive age group, who according to literature may be at risk of adverse pregnancy outcomes. This pilot study is part of a study investigating adverse pregnancy outcomes among women who received Cryotherapy, Thermal ablation and Loop Electrosurgical Excision Procedure compared to the untreated women in Zambia. Materials and Methods: This descriptive study analyzed records of 886 (n = 443 treated and n = 443 untreated) women aged 15 - 49 years. The women were either screened with Visual Inspection with Acetic Acid or treated for Cervical Intraepithelial neoplasia at the Adult Infectious Disease Centre between January 2010 and December 2020. Women meeting the criteria were identified using the Visual Inspection with Acetic Acid screening records and telephone interviews to obtain the adverse pregnancy outcome experienced. Data were analysed using STATA version 16 to determine the prevalence and obtain frequency distribution of outcomes of interest. Univariate and multivariable binary logistic regression estimated odds of adverse pregnancy outcomes across the three treatments. Results: The respondents were aged 15 to 49 years. Adverse pregnancy outcomes were observed to be more prevalent in the treatment group (18.5%) compared to the untreated group (5.4%). Normal pregnancy outcomes were lower in the treated (46.3%;n = 443) than the untreated (53.7%;n = 443). The treated group accounted for the majority of abortions (85.2%), prolonged labour (85.7%) and low birth weight (80%), whereas, the untreated accounted for the majority of still births (72.7%). Women treated with cryotherapy (aOR = 2.43, 95% CI = 1.32 - 4.49, p = 0.004), thermal ablation (aOR = 6.37, 95% CI = 0.99 - 41.2, p = 0.052) and Loop Electrosurgical Excision Procedure (aOR = 9.67, 95% CI = 2.17 - 43.1, p = 0.003) had two-, six- and ten-times higher odds of adverse pregnancy outcomes respectively, relative to women who required no treatment. Conclusion: Adverse pregnancy outcomes are prevalent among women who have received treatment in Zambia. The findings indicate that treating Cervical Intraepithelial Neoplasia has been linked to higher chances of experiencing abortion, delivering low birth weight babies and enduring prolonged labor that may result in a caesarean section delivery. Cervical neoplasia treatments, particularly Loop Electrosurgical Excision Procedure, are associated with significantly increased odds of adverse pregnancy outcomes. It is essential to include information about prior Cervical Intraepithelial neoplasia treatment outcomes in obstetric care.展开更多

Its prevalence in pregnancy is estimated at 14% in Cameroon. Objective: The main objective of this study was to determine the adverse pregnancy outcomes associated with obesity in the Regional Hospital Bamenda. Methodology: This was a hospital-based cross-sectional study. We recruited 283 participants and their BMIs were used to classify them as underweight ( - 24.9), overweight (25 - 29.9) and obese (≥30). Ethical clearance, administrative authorisation and consent of participants were obtained. Data was collected using a pretested questionnaire. We collected data on sociodemographic characteristics, anthropometric characteristics, and adverse pregnancy outcomes. Data was analysed using Microsoft Excel version 2010. Fisher’s test was used to determine relative risk on bivariate logistic regression. P-values < 0.05 were considered statistically significant. Results: Most participants were in the age group 20 - 34 years, and were multigravida and multipara. The prevalence of maternal obesity was 31.4%. Obesity was associated with an increased risk of hypertensive disorders [RR: 7.7, 95% CI (2.13 - 42.39), p = 0.0003], caesarean section [RR: 2.9, 95% CI (1.11 - 4.01), p = 0.017] and macrosomia [RR: 7.3, 95% CI (3.03 - 19.61), p Conclusion: Maternal obesity is associated with hypertensive disorders, caesarean section and macrosomia.展开更多

The presence of COVID-19 in a pregnant patient can raise concerns, as other types of coronaviruses were associated with many adverse outcomes. This study aims to study the effect of COVID-19 on pregnancy outcomes. Methods: A prospective cross-sectional cohort study within Central First Health Care Cluster (multicentric), Riyadh, included all pregnant women with a singleton pregnancy diagnosed as COVID-19-positive. The primary outcome is the severity of COVID during pregnancy in terms of ICU admission and mortality. The participants were divided into three groups (preterm less than 37 weeks, the term from 37 - 40 weeks, and late-term after 40 weeks. In addition, parameters included: Gestational age at diagnosis, symptoms at presentation (cough, fever), presence of congenital anomalies, IUFD, mode of delivery, presence of PPH, newborn Apgar score, cord PH, need for NICU admission, and the newborn becoming infected with COVID-19 were also measured as secondary outcomes. Results: One hundred pregnant, COVID-19-positive women met the inclusion criteria;the average age of participants was 31.2 years (SD ± 6.4). Asymptomatic patients represented 54% of participants. Most of the deliveries occurred at 36 weeks or less as preterm delivery. Cesarean sections represented 55% of our population. Four-term mothers (12.5%), more than 37 weeks, need ICU admission compared to 13 (25%) preterm cases diagnosed with preeclampsia. No maternal death. Conclusion: COVID-19 during pregnancy can increase ICU admission. A high rate of preterm labor, miscarriage, cesarean section, and newborn testing positive for COVID-19 were observed among our population. No congenital anomalies related to COVID-19 were observed.展开更多

It was unclear whether untreated PTB would affect pregnancy outcomes after IVF-ET.Method We conducted a retrospective cohort study of 14,254 infertile patients who had received IVFET at Peking University Third Hospital in 2017. Prior PTB was defined as the presence of signs suggestive of old or inactive PTB on CXR, with or without a clinical TB history. Patients who had prior PTB on CXR but had not received a clinical diagnosis and anti-TB therapy were included for analysis. Live birth,clinical pregnancy, and miscarriage rates were compared between the untreated PTB and non-PTB groups.Results The untreated PTB group had significantly lower clinical pregnancy(31.7% vs. 38.1%) and live birth(23.8% vs. 30.6%) rates than the non-PTB group(both P < 0.001). Multivariate analysis revealed that untreated PTB was a risk factor for decreased live birth rate [odds ratio(OR), 0.80;95% confidence interval(CI), 0.66–0.98;P = 0.028] in all patients and for increased miscarriage(OR, 4.19;95% CI,1.69–10.39;P = 0.002) and decreased live birth(OR, 0.45;95% CI, 0.24–0.83;P = 0.011) rates in patients with unexplained infertility.Conclusions Untreated PTB was associated with adverse pregnancy outcomes after IVF-ET, especially in patients with unexplained infertility, highlighting the clinical significance of PTB in this specific patient population.展开更多

Also, the association between HBV-related risk factors and HBV status was studied.Methods: A total of 100 HBV positive pregnant women were recruited and the pregnancy outcomes were compared with 301 HBV negative women. Blood samples were collected and tested for HBV by HBs Ag ELISA. Data were collected for recruited subjects using interview questionnaire.Results: Data analysis showed that 51/100(51%) of the HBV-positive subjects gave a history of HBV in the family which was significantly higher than that of HBV-negative patients [41/301(13.6%) P = 0.001]. A significant association was found between positive history of surgery and HBs Ag positivity(P = 0.009). Then, pregnancy outcomes were stratified according to the HBV positivity. No significant association was found between HBV status and pregnancy outcomes(P > 0.05 for all).Conclusions: Positive family history of HBV and previous surgical procedures are associated with higher rate of HBV positivity. No association is found between HBV positivity and pregnancy outcomes.展开更多

This continuous unacceptably high maternal mortality justifies a need for progressive research to better understand the predictors of the preventive behaviors of women towards adverse pregnancy outcomes. This study was conducted to assess levels of knowledge, attitudes about adverse pregnancy outcomes and preventive practices among women of reproductive age in Nassarawa local government area, Kano State, Nigeria. <strong>Methodology:</strong> The study was a cross-sectional descriptive study that employed a four-sectioned pretested researcher administered questionnaire to collect data on knowledge, attitude and practice of adverse pregnancy outcomes prevention among 164 consenting respondents in Kano State, Nigeria between November 2020 and December 2020. Responses were transformed and computed using SPSS version 26 to generate descriptive statistics. Regression analysis was done to test the degree of association between the predictors and practice of adverse pregnancy outcomes prevention with the level of significance set at a cut-off of p ≤ 0.05. <strong>Results:</strong> The findings showed that the majority of the respondents were between 20 - 24 years of age and had secondary educational attainment. Results further revealed that knowledge and attitude about adverse pregnancy outcomes which were both measured on 18-point scales, reported for the respondents’ mean scores of 9.46 (9.07 ± 9.85) and 10.72 (9.79 ± 10.62) respectively. The practice of adverse pregnancy outcomes prevention when assessed on a 15-point scale shows that respondents scored a mean of 7.42 ± 8.30 which denotes 53.4% of the level of prevention practice anticipated from the respondents. The study also showed a significant positive association between the level of knowledge (p = 0.010), attitude (p < 0.001) and prevention practice of adverse pregnancy outcomes.<strong> Conclusions:</strong> The findings reported an average but inadequate knowledge and neutral attitude that predicted unsatisfactory adverse pregnancy outcomes prevention practices among the examined reproductive-aged women, which calls for targeted health education on adverse pregnancy outcomes within the community in order to inform better prevention practices.展开更多

This study aims at exploring the outcomes of pregnancy and associated factors in hypertensive pregnant women in Comè district hospital from 2014 to 2016. <strong>Methods:</strong> This is a retrospective, analytical study carried out in June 2016, involving a total of 345 hypertensive patients. Socio-demographic and medical features, including pregnancy and foetal outcomes parameters, were recorded in the case files. Top-down stepwise logistic regression was performed at the 5% threshold. <strong>Results:</strong> The frequency of hypertensive disorders during pregnancy was estimated at 7.32% and unfavourable outcomes at 35.65%. The adverse maternal outcomes recorded were postpartum death and haemorrhage whereas adverse foetal issues were prematurity, low birth weight, low Apgar scores, stillbirth and death. Factors statistically associated with pregnancy outcome were paucigravida (OR = 2.01 ([1.05 - 3.88]), p = 0.035), history of stillbirth (OR = 4.75 ([1.01 - 22.1]), p = 0.048) and anticonvulsant therapy (OR = 0.32 ([0.19 - 0.54]), p < 0.001). <strong>Conclusion:</strong> Adequate monitoring via Antenatal Care (ANC) check-ups, timely recourse to care and an effective communication strategy should reduce hypertensive disorders incidence and adverse outcomes in pregnant women.展开更多

Healthy workplaces include addressing the unique needs of nurses who work while pregnant. The purpose of this descriptive study, summarizing information from 120 pregnancies reported by 95 nurses, was to determine if the workload of obstetrical nurses was associated with negative pregnancy outcomes, including preterm delivery and birth weight. Full-time obstetrical nursing work is a predictor of reduced birth weight, but not of preterm birth when compared to outcomes of obstetrical nurses working part time. One third of nurses reported pregnancy complications and most nurses experienced work-related and personal stress. Further research evaluating work modifications during pregnancy is indicated to improve birth outcomes.展开更多

Methods A total of 156 women were given randomly in double blind 5mg/d (group A, GPA, n=37),10mg/d (group B, GPB, n=40), 30mg (group C, GpC, n = 39) Of zinc supplement or placebo (group D, GpD, n = 40 ) starting from, the first visit at the prenatal clinic (average 9-week gestation ) till the delivery. Results Mean dietary zinc intake of these women was about 10mg/d, and more than 65% of dietary zinc were taken from cereals, grains and vegetables. Serum zinc concentrations at 25-and 32-gestation in GpC and in the umbilical cord blood of their babies at birth significantly increased. Infants in GpC had a significantly heavier birth weight (283. 079, P = 0. 016 ) and larger head circumference(0. 63cm, P = 0. 035) than infants in GpD. The incidence of low birth weight, preterm and intrauterine growth retardation infants was significantly reduced in GpC. As compared to GpD (38. 34 ± 1. 34 weeks), the duration of gestation in GpD(39. 12± 1. 11 weeks) was prolonged (P= 0. 032). Serum zinc concentration at 25-weeks gestation was negatively correlated with duration of gestation (P = 0. 009 ). Apgar score of the infants in GpC was significantly higher than that in GpD, and serum zinc concentration at 32-weeks gestation was positively associated with infant Apgar score (P = 0. 015 ). Conclusion Zinc supplementation in 30mg/d to Chinese rural women during pregnancy could significantly improve their pregnancy outcome. Both 5mg/d and 10mg/d of zinc supplementation had no detected benefits to them.展开更多

文摘Objective:To evaluate the effect of bilateral hypogastric artery ligation(BHGAL)on women's pregnancy outcomes and fertility rates in cases with severe postpartum hemorrhage.Methods:Patients hospitalized in a tertiary care center between 2007 and 2018 were included in the study.The records of cases were obtained from the hospital database,retrospectively.Maternal demographic data,morbidities or complications associated with BHGAL surgery,any additional haemostatic interventional or surgical procedures,preoperative admission and lowest postoperative haematocrit-hemoglobin values,blood products given,type of anaesthesia,intensive care unit(ICU)and length of hospital stay were recorded.In cases without surgical sterilization,future fertility and subsequent pregnancy outcomes were assessed for at least two years after operation.Information was obtained through face-to-face or telephone interviews with patients whose long-term fertility and subsequent pregnancy outcomes were assessed.Results:Sixty-eight patients with BHGAL surgery history were included in the study.26 Of 37 cases(70%)that did not undergo surgical sterilization had a desire for pregnancy after the surgery.Six of these cases(23%)were diagnosed with secondary infertility.The fertility rate of these cases was 77%,and subsequent pregnancy was detected in 20 women.A total of 25 pregnancies,including first and second pregnancies,developed,and 15 of these pregnancies resulted in term delivery,six preterm births,one stillbirth,and three abortions.Conclusions:The postoperative pregnancy rate was found to be higher than the rate of women with infertility problems,and this surgery does not seem to adversely affect pregnancy outcomes.This is a tertiary center experience and cohort studies with large patient series are needed.
文摘Background: Cervical Intraepithelial neoplasia treatments have become essential interventions to manage cervical lesions. Majority of the recipients of these treatments are women within the reproductive age group, who according to literature may be at risk of adverse pregnancy outcomes. This pilot study is part of a study investigating adverse pregnancy outcomes among women who received Cryotherapy, Thermal ablation and Loop Electrosurgical Excision Procedure compared to the untreated women in Zambia. Materials and Methods: This descriptive study analyzed records of 886 (n = 443 treated and n = 443 untreated) women aged 15 - 49 years. The women were either screened with Visual Inspection with Acetic Acid or treated for Cervical Intraepithelial neoplasia at the Adult Infectious Disease Centre between January 2010 and December 2020. Women meeting the criteria were identified using the Visual Inspection with Acetic Acid screening records and telephone interviews to obtain the adverse pregnancy outcome experienced. Data were analysed using STATA version 16 to determine the prevalence and obtain frequency distribution of outcomes of interest. Univariate and multivariable binary logistic regression estimated odds of adverse pregnancy outcomes across the three treatments. Results: The respondents were aged 15 to 49 years. Adverse pregnancy outcomes were observed to be more prevalent in the treatment group (18.5%) compared to the untreated group (5.4%). Normal pregnancy outcomes were lower in the treated (46.3%;n = 443) than the untreated (53.7%;n = 443). The treated group accounted for the majority of abortions (85.2%), prolonged labour (85.7%) and low birth weight (80%), whereas, the untreated accounted for the majority of still births (72.7%). Women treated with cryotherapy (aOR = 2.43, 95% CI = 1.32 - 4.49, p = 0.004), thermal ablation (aOR = 6.37, 95% CI = 0.99 - 41.2, p = 0.052) and Loop Electrosurgical Excision Procedure (aOR = 9.67, 95% CI = 2.17 - 43.1, p = 0.003) had two-, six- and ten-times higher odds of adverse pregnancy outcomes respectively, relative to women who required no treatment. Conclusion: Adverse pregnancy outcomes are prevalent among women who have received treatment in Zambia. The findings indicate that treating Cervical Intraepithelial Neoplasia has been linked to higher chances of experiencing abortion, delivering low birth weight babies and enduring prolonged labor that may result in a caesarean section delivery. Cervical neoplasia treatments, particularly Loop Electrosurgical Excision Procedure, are associated with significantly increased odds of adverse pregnancy outcomes. It is essential to include information about prior Cervical Intraepithelial neoplasia treatment outcomes in obstetric care.
文摘BACKGROUND Intrahepatic cholestasis of pregnancy(ICP)is a liver disorder that occurs in pregnant women and can lead to a range of adverse pregnancy outcomes.The condition is typically marked by pruritus(itching)and elevated levels of liver enzymes and bile acids.The standard treatment for ICP has generally been ursodeoxycholic acid and ademetionine 1,4-butanedisulfonate,but the efficacy of this approach remains less than optimal.Recently,polyene phosphatidylcholine has emerged as a promising new therapeutic agent for ICP due to its potential hepatoprotective effects.AIM To evaluate the effect of polyene phosphatidylcholine/ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate on bile acid levels,liver enzyme indices,and pregnancy outcomes in patients with ICP.METHODS From June 2020 to June 2021,600 patients with ICP who were diagnosed and treated at our hospital were recruited and assigned at a ratio of 1:1 via randomnumber table method to receive either ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate(control group,n=300)or polyene phosphatidylcholine/ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate(combined group,n=300).Outcome measures included bile acids levels,liver enzyme indices,and pregnancy outcomes.RESULTS Prior to treatment,no significant differences were observed between the two groups(P>0.05).Post-treatment,patients in both groups had significantly lower pruritus scores,but the triple-drug combination group had lower scores than the dual-drug combination group(P<0.05).The bile acid levels decreased significantly in both groups,but the decrease was more significant in the triple-drug group(P<0.05).The triple-drug group also exhibited a greater reduction in the levels of certain liver enzymes and a lower incidence of adverse pregnancy outcomes compared to the dual-drug group(P<0.05).CONCLUSION Polyene phosphatidylcholine/ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate effectively relieves pruritus and reduces bile acid levels and liver enzyme indices in patients with ICP,providing a positive impact on pregnancy outcome and a high safety profile.Further clinical trials are required prior to clinical application.
文摘BACKGROUND There are many drawbacks to the traditional midwifery service management model,which can no longer meet the needs of the new era.The Internet+continuous midwifery service management model extends maternal management from prenatal to postpartum,in-hospital to out-of-hospital,and offline to online,thereby improving maternal and infant outcomes.Applying the Internet+continuous midwifery service management model to manage women with highrisk pregnancies(HRP)can improve their psycho-emotional opinion and,in turn,minimize the risk of adverse maternal and/or fetal outcomes.AIM To explore the effectiveness of a midwife-led Internet+continuous midwifery service model for women with HRP.METHODS We retrospectively analyzed the clinical data of 439 women with HRP who underwent prenatal examination and delivered at Shanghai Sixth People's Hospital(affiliated to the Shanghai Jiao Tong University School of Medicine)from April to December 2022.Among them,239 pregnant women underwent routine obstetric management,and 200 pregnant women underwent Internet+continuous midwifery service mode management.We used the State-Trait Anxiety Inventory,Edinburgh Postnatal Depression Scale,and analysis of delivery outcomes to compare psychological mood and the incidence of adverse delivery outcomes between the two groups.RESULTS The data showed that in early pregnancy,the anxiety and depression levels of the two groups were similar;the levels gradually decreased as pregnancy progressed,and the decrease in the continuous group was more significant[31.00(29.00,34.00)vs 34.00(32.00,37.00),8.00(6.00,9.00)vs 12.00(10.00,13.00),P<0.05].The maternal self-efficacy level and strategy for weight gain management were better in the continuous group than in the traditional group,and the effective rate of midwifery service intervention in the continuous group was significantly higher than in the control group[267.50(242.25,284.75)vs 256.00(233.00,278.00),74.00(69.00,78.00)vs 71.00(63.00,78.00),P<0.05].The incidence of adverse delivery outcomes in pregnant women and newborns and fear of maternal childbirth were lower in the continuous group than in the traditional group,and nursing satisfaction was higher[10.50%vs 18.83%,8.50%vs 15.90%,24.00%vs 42.68%,89.50%vs 76.15%,P<0.05].CONCLUSION The Internet+continuous midwifery service model promotes innovation through integration and is of great significance for improving and promoting maternal and child health in HRP.

文摘Objective:To systematically evaluate the relationship between herpes simplex virus type II(HSV-2)infection in pregnant women and the adverse pregnancy outcomes(preterm delivery,spontaneous abortion,stillbirth,monstrum,low birth weight,intrauterine growth retardation,premature rupture of membranes),so as to provide clinical guidance for the prevention and treatment of adverse pregnancy outcomes caused by HSV-2 infection in pregnant women.Methods:2140 articles were collected from PubMed,China National Knowledge Infrastructure(CNKI),and other databases for the past 20 years.According to the inclusion criteria,the literatures about the relationship between HSV-2 infection of pregnant women and adverse pregnancy outcomes were screened.The effect model was determined by heterogeneity test results,and the meta-analysis was carried out by RevMan 5.3 software.Results:The results of meta-analysis showed that the positive rate of HSV-2 was higher in the adverse pregnancy group than in the control group(odds ratio[OR]:7.92,95%confidence interval[Cl]:3.91-16.01),and the difference was statistically significant.Conclusion:HSV-2 infection will increase the risk of adverse pregnancy outcomes.Prevention and effective control of HSV-2 infection in early pregnancy can reduce the rate of adverse pregnancy outcome,which is of great significance to the promotion of eugenics.
文摘Introduction: Obesity is one of the most common problems of reproductive age women and has been associated with diverse adverse pregnancy outcomes. Its prevalence in pregnancy is estimated at 14% in Cameroon. Objective: The main objective of this study was to determine the adverse pregnancy outcomes associated with obesity in the Regional Hospital Bamenda. Methodology: This was a hospital-based cross-sectional study. We recruited 283 participants and their BMIs were used to classify them as underweight ( - 24.9), overweight (25 - 29.9) and obese (≥30). Ethical clearance, administrative authorisation and consent of participants were obtained. Data was collected using a pretested questionnaire. We collected data on sociodemographic characteristics, anthropometric characteristics, and adverse pregnancy outcomes. Data was analysed using Microsoft Excel version 2010. Fisher’s test was used to determine relative risk on bivariate logistic regression. P-values < 0.05 were considered statistically significant. Results: Most participants were in the age group 20 - 34 years, and were multigravida and multipara. The prevalence of maternal obesity was 31.4%. Obesity was associated with an increased risk of hypertensive disorders [RR: 7.7, 95% CI (2.13 - 42.39), p = 0.0003], caesarean section [RR: 2.9, 95% CI (1.11 - 4.01), p = 0.017] and macrosomia [RR: 7.3, 95% CI (3.03 - 19.61), p Conclusion: Maternal obesity is associated with hypertensive disorders, caesarean section and macrosomia.
文摘Introduction: Acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was declared a pandemic by the World Health Organization (WHO) on March 11, 2020. The presence of COVID-19 in a pregnant patient can raise concerns, as other types of coronaviruses were associated with many adverse outcomes. This study aims to study the effect of COVID-19 on pregnancy outcomes. Methods: A prospective cross-sectional cohort study within Central First Health Care Cluster (multicentric), Riyadh, included all pregnant women with a singleton pregnancy diagnosed as COVID-19-positive. The primary outcome is the severity of COVID during pregnancy in terms of ICU admission and mortality. The participants were divided into three groups (preterm less than 37 weeks, the term from 37 - 40 weeks, and late-term after 40 weeks. In addition, parameters included: Gestational age at diagnosis, symptoms at presentation (cough, fever), presence of congenital anomalies, IUFD, mode of delivery, presence of PPH, newborn Apgar score, cord PH, need for NICU admission, and the newborn becoming infected with COVID-19 were also measured as secondary outcomes. Results: One hundred pregnant, COVID-19-positive women met the inclusion criteria;the average age of participants was 31.2 years (SD ± 6.4). Asymptomatic patients represented 54% of participants. Most of the deliveries occurred at 36 weeks or less as preterm delivery. Cesarean sections represented 55% of our population. Four-term mothers (12.5%), more than 37 weeks, need ICU admission compared to 13 (25%) preterm cases diagnosed with preeclampsia. No maternal death. Conclusion: COVID-19 during pregnancy can increase ICU admission. A high rate of preterm labor, miscarriage, cesarean section, and newborn testing positive for COVID-19 were observed among our population. No congenital anomalies related to COVID-19 were observed.
文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection may have harmful effects on expectant moms,labor,and newborns born to infected mothers.There is a risk of the initiation of pregnancy with infection.Even if the gametes are non-infected,pregnancies could be exposed later for infection by coronavirus.Investigations of COVID-19 during pregnancy highlighted the non-transmission or surprising transmission of SARS-CoV-2 to the offspring.However,other studies have exhibited the potential mother-to-fetus transmission.In this way,unanswered concerns about SARS-CoV-2 fetal transmission and the particular interface(s)controlling its pathogenesis throughout pregnancy persist.This review focuses on the potential effects of SARS-CoV-2 on vertical transmission,as well as the influence of the virus on pregnancy and placenta.

文摘Objective Prior pulmonary tuberculosis(PTB) on chest X-ray(CXR) was commonly found in infertile patients receiving examinations before in vitro fertilization and embryo transfer(IVF-ET). It was unclear whether untreated PTB would affect pregnancy outcomes after IVF-ET.Method We conducted a retrospective cohort study of 14,254 infertile patients who had received IVFET at Peking University Third Hospital in 2017. Prior PTB was defined as the presence of signs suggestive of old or inactive PTB on CXR, with or without a clinical TB history. Patients who had prior PTB on CXR but had not received a clinical diagnosis and anti-TB therapy were included for analysis. Live birth,clinical pregnancy, and miscarriage rates were compared between the untreated PTB and non-PTB groups.Results The untreated PTB group had significantly lower clinical pregnancy(31.7% vs. 38.1%) and live birth(23.8% vs. 30.6%) rates than the non-PTB group(both P < 0.001). Multivariate analysis revealed that untreated PTB was a risk factor for decreased live birth rate [odds ratio(OR), 0.80;95% confidence interval(CI), 0.66–0.98;P = 0.028] in all patients and for increased miscarriage(OR, 4.19;95% CI,1.69–10.39;P = 0.002) and decreased live birth(OR, 0.45;95% CI, 0.24–0.83;P = 0.011) rates in patients with unexplained infertility.Conclusions Untreated PTB was associated with adverse pregnancy outcomes after IVF-ET, especially in patients with unexplained infertility, highlighting the clinical significance of PTB in this specific patient population.
文摘Objective: To investigate the relationship between hepatitis B virus(HBV) positivity and pregnancy outcomes. Also, the association between HBV-related risk factors and HBV status was studied.Methods: A total of 100 HBV positive pregnant women were recruited and the pregnancy outcomes were compared with 301 HBV negative women. Blood samples were collected and tested for HBV by HBs Ag ELISA. Data were collected for recruited subjects using interview questionnaire.Results: Data analysis showed that 51/100(51%) of the HBV-positive subjects gave a history of HBV in the family which was significantly higher than that of HBV-negative patients [41/301(13.6%) P = 0.001]. A significant association was found between positive history of surgery and HBs Ag positivity(P = 0.009). Then, pregnancy outcomes were stratified according to the HBV positivity. No significant association was found between HBV status and pregnancy outcomes(P > 0.05 for all).Conclusions: Positive family history of HBV and previous surgical procedures are associated with higher rate of HBV positivity. No association is found between HBV positivity and pregnancy outcomes.

文摘Objective:To investigate the influence of serum E2 level on pregnancy outcome on endometrial transformation day in hormone replacement therapy-thawed embryo transfer(HRT-FET)cycle.Methods:Totally 834 embryo transfer cycles of cleavage stage treated by HRT-FET in Reproductive Center of First Affiliated Hospital of Hainan Medical College from December 2014 to December 2019 were analyzed retrospectively.Results:The number of transplanted embryos in group A was higher than that in group B,and the difference was statistically significant(P<0.05);The thickness and serum P level of endometrial transformation day in Group B were significantly higher than those in Group A(P<0.05);There was no significant difference in clinical pregnancy rate,implantation rate,abortion rate,ectopic pregnancy rate,biochemical pregnancy rate and live birth rate between Group A and Group B(P>0.05);There was no statistical difference in general data between group A1 and group A2,group B1 and group B2(P>0.05);There was no significant difference in clinical pregnancy rate,implantation rate,abortion rate,ectopic pregnancy rate,biochemical pregnancy rate and live birth rate between group B1 and group B2(P>0.05);The clinical pregnancy rate,implantation rate and live birth rate in group A2 were significantly higher than those in group A1(P<0.05).Conclusions:Endometrial type A or B has no significant effect on pregnancy outcome in hormone replacement therapy-thawed embryo transfer cycle.;In type A endometrium,the serum E2>827 pmol/L on the day of endometrial transformation is helpful to improve the pregnancy outcome of frozen-thawed embryo transfer.
文摘<strong>Background:</strong> Adverse pregnancy outcomes continue to contribute substantially to maternal mortality as well as poor maternal and fetal health outcomes whose burden can be reduced by the initiation of preventive behaviors like the uptake of maternal health services. This continuous unacceptably high maternal mortality justifies a need for progressive research to better understand the predictors of the preventive behaviors of women towards adverse pregnancy outcomes. This study was conducted to assess levels of knowledge, attitudes about adverse pregnancy outcomes and preventive practices among women of reproductive age in Nassarawa local government area, Kano State, Nigeria. <strong>Methodology:</strong> The study was a cross-sectional descriptive study that employed a four-sectioned pretested researcher administered questionnaire to collect data on knowledge, attitude and practice of adverse pregnancy outcomes prevention among 164 consenting respondents in Kano State, Nigeria between November 2020 and December 2020. Responses were transformed and computed using SPSS version 26 to generate descriptive statistics. Regression analysis was done to test the degree of association between the predictors and practice of adverse pregnancy outcomes prevention with the level of significance set at a cut-off of p ≤ 0.05. <strong>Results:</strong> The findings showed that the majority of the respondents were between 20 - 24 years of age and had secondary educational attainment. Results further revealed that knowledge and attitude about adverse pregnancy outcomes which were both measured on 18-point scales, reported for the respondents’ mean scores of 9.46 (9.07 ± 9.85) and 10.72 (9.79 ± 10.62) respectively. The practice of adverse pregnancy outcomes prevention when assessed on a 15-point scale shows that respondents scored a mean of 7.42 ± 8.30 which denotes 53.4% of the level of prevention practice anticipated from the respondents. The study also showed a significant positive association between the level of knowledge (p = 0.010), attitude (p < 0.001) and prevention practice of adverse pregnancy outcomes.<strong> Conclusions:</strong> The findings reported an average but inadequate knowledge and neutral attitude that predicted unsatisfactory adverse pregnancy outcomes prevention practices among the examined reproductive-aged women, which calls for targeted health education on adverse pregnancy outcomes within the community in order to inform better prevention practices.
文摘<strong>Introduction:</strong> Hypertension is a major cause of maternal and perinatal morbidity and mortality. This study aims at exploring the outcomes of pregnancy and associated factors in hypertensive pregnant women in Comè district hospital from 2014 to 2016. <strong>Methods:</strong> This is a retrospective, analytical study carried out in June 2016, involving a total of 345 hypertensive patients. Socio-demographic and medical features, including pregnancy and foetal outcomes parameters, were recorded in the case files. Top-down stepwise logistic regression was performed at the 5% threshold. <strong>Results:</strong> The frequency of hypertensive disorders during pregnancy was estimated at 7.32% and unfavourable outcomes at 35.65%. The adverse maternal outcomes recorded were postpartum death and haemorrhage whereas adverse foetal issues were prematurity, low birth weight, low Apgar scores, stillbirth and death. Factors statistically associated with pregnancy outcome were paucigravida (OR = 2.01 ([1.05 - 3.88]), p = 0.035), history of stillbirth (OR = 4.75 ([1.01 - 22.1]), p = 0.048) and anticonvulsant therapy (OR = 0.32 ([0.19 - 0.54]), p < 0.001). <strong>Conclusion:</strong> Adequate monitoring via Antenatal Care (ANC) check-ups, timely recourse to care and an effective communication strategy should reduce hypertensive disorders incidence and adverse outcomes in pregnant women.
文摘The Registered Nurses Association of Ontario Healthy Work Environments Best Practice Guideline recommends that employers promote safe, healthy workplaces. Healthy workplaces include addressing the unique needs of nurses who work while pregnant. The purpose of this descriptive study, summarizing information from 120 pregnancies reported by 95 nurses, was to determine if the workload of obstetrical nurses was associated with negative pregnancy outcomes, including preterm delivery and birth weight. Full-time obstetrical nursing work is a predictor of reduced birth weight, but not of preterm birth when compared to outcomes of obstetrical nurses working part time. One third of nurses reported pregnancy complications and most nurses experienced work-related and personal stress. Further research evaluating work modifications during pregnancy is indicated to improve birth outcomes.
文摘Objective:The relationship between serum beta human chorionic gonadotropin(β-hCG)levels of patients(7 days after the transplantation of frozen-thawed embryos)and the pregnancy outcomes was investigated.Methods:This study was designed as a retrospective clinical trial of 366 women who underwent frozen-thawed embryo transfers(FETs)in artificial cycles.Patients were divided into three groups:clinical pregnancy group,biochemical pregnancy group,and non-pregnant group according to their pregnancy outcomes.Serumβ-hCG levels were tested on day 4,7,9,11 and 14 after FET.Results:In the clinical pregnancy group,the serumβ-hCG levels after 7-day post-transplantation were significantly elevated(16.20 IU/L vs.3.07 vs.0.1 IU/L;P<0.05)compared with the other two groups.Furthermore,it was found that Area Under Curve(AUC=0.96)was significant with cut-off value higher than 4.26 IU/L(sensitivity=92.3%,specificity=90.2%)to predict the clinical pregnancy outcomes in the receiver operating characteristic(ROC)analysis ofβ-hCG concentrations on day 7 of post-transplantation.Conclusion:Our results suggested that the elevated serumβ-hCG levels on day 7 of post-transplantation could predict the positive clinical pregnancy outcomes in artificial FET cycles.
文摘Objective: TO assess the effects of zinc supplementation to Chinese rural pregnant with cereal-based diet and their pregnancy outcome. Methods A total of 156 women were given randomly in double blind 5mg/d (group A, GPA, n=37),10mg/d (group B, GPB, n=40), 30mg (group C, GpC, n = 39) Of zinc supplement or placebo (group D, GpD, n = 40 ) starting from, the first visit at the prenatal clinic (average 9-week gestation ) till the delivery. Results Mean dietary zinc intake of these women was about 10mg/d, and more than 65% of dietary zinc were taken from cereals, grains and vegetables. Serum zinc concentrations at 25-and 32-gestation in GpC and in the umbilical cord blood of their babies at birth significantly increased. Infants in GpC had a significantly heavier birth weight (283. 079, P = 0. 016 ) and larger head circumference(0. 63cm, P = 0. 035) than infants in GpD. The incidence of low birth weight, preterm and intrauterine growth retardation infants was significantly reduced in GpC. As compared to GpD (38. 34 ± 1. 34 weeks), the duration of gestation in GpD(39. 12± 1. 11 weeks) was prolonged (P= 0. 032). Serum zinc concentration at 25-weeks gestation was negatively correlated with duration of gestation (P = 0. 009 ). Apgar score of the infants in GpC was significantly higher than that in GpD, and serum zinc concentration at 32-weeks gestation was positively associated with infant Apgar score (P = 0. 015 ). Conclusion Zinc supplementation in 30mg/d to Chinese rural women during pregnancy could significantly improve their pregnancy outcome. Both 5mg/d and 10mg/d of zinc supplementation had no detected benefits to them.

文摘Objective:To evaluate cervical function and pregnancy outcomes after hysteroscopic resection of the complete uterine septum,duplicate cervix and vaginal septum with Metzenbaum scissors.Methods:Between January 2010 and December 2016,13 patients admitted to the Department of Obstetrics and Gynecology of Sir Run Run Shaw Hospital with complete uterine septum,duplicate cervix and vaginal septum,were enrolled into this study.The cervical and corporal septum was cut by Metzenbaum scissors,and residual septum was cut by micro scissors under hysteroscopy.The vaginal septum was cut with the unipolar electric knife.Results:The operation time was about 10±1.31 min.All the 13 patients present normal uterine cavities without scar formation under hysteroscopy at 3 months after operation,there was mild adhesions between anterior and posterior intrauterine wall on 2 cases.After operation,there were 13 pregnancies naturally conceived in 11 patients,10 deliveries.The live birth rate was 76.92%,the early miscarriage rate was 23.08%.The cesarean section ratewas 30%,the vaginal delivery ratewas 70%,and all were term births.Conclusion:The operation was simple,convenient,and fast,without any complications and cervical insufficiency.It was easy to have vaginal deliveries.
